European debt woes stalk markets

LONDON (AP) — Worries over Europe's debt crisis kept markets on edge Monday, following a warning over Italy's credit rating and a failure by eurozone finance ministers to agree an immediate release of bailout funds to Greece.

However, a brighter than anticipated opening on Wall Street helped stocks in Europe to recover from earlier lows and shored up the euro currency — an improvement in investors' risk appetite often gives the euro a lift.

In Europe, the FTSE 100 index of leading British shares was down 0.3 percent at 5,699 while Germany's DAX fell 0.3 percent to 7,145. The CAC-40 in France was 0.9 percent lower at 3,137.

Oil Prices Fall As Inventories Jump

Oil prices fell Wednesday after the Energy Department said crude oil and gasoline supplies jumped much more than expected last week. Inventories of distillates, which include heating oil and diesel, fell less than forecast.

The Energy Information Administration report injected a dose of bearish sentiment into a market that has set new records in 11 of the past 12 sessions. Crude oil supplies jumped by 6.2 million barrels last week, more than three times the 1.6 million barrel increase analysts surveyed by Dow Jones Newswires were expecting.

It was the eight increase in crude supplies in nine weeks, putting oil inventories back on a growth track after a …

Religion News in Brief

The head of the Egyptian Coptic Church threatened to excommunicate priests who perform second marriages after a court ruled that divorced Copts could remarry.

Pope Shenouda III strongly condemned the verdict, which he said goes against the Bible. He said priests who perform these marriages, along with those requesting to remarry, will not be allowed to enter the church again as they are considered "deviants." He explained only those divorced on grounds of adultery can remarry.

"The issue of remarriage for those divorced is a specifically religious matter that only the Bible can dictate," Shenouda said Tuesday.

FDA debates over-the-counter morning-after pill

WASHINGTON (AP) — The U.S. government is considering whether it's OK for young teenagers to buy emergency contraception without a prescription.

Teva Pharmaceuticals wants its Plan B morning-after pill to become the first truly over-the-counter form of emergency contraception. The pill can prevent pregnancy if taken soon after unprotected sex. Currently, women 17 and older can buy it without a prescription if they show a pharmacist proof of age. Younger teens need a prescription.

Doctors' and women's health groups have long argued that the pill is safe even for younger teens and that lifting the age restriction would increase access for everyone. If the Food and Drug Administration agrees, Plan B One-Step could be moved from behind the counter to sell on drugstore shelves. Teva was expecting a decision on Wednesday.

Jasper Johns proofs go on view at National Gallery

The National Gallery of Art is opening an exhibit showing working proofs of artist Jasper Johns as independent pieces of art for the first time.

The two-room exhibit opens Sunday and highlights his proofs from 1962 to 1997. It includes 42 works on paper that show how Johns' refined his style over time.

The artist's working proofs are prints on which Johns drew or painted additions during the working process. Some show techniques and symbols he repeats in many works over time, such as silhouettes of his artistic predecessors Marcel Duchamp and Pablo Picasso.

Curator Ruth Fine says visitors will see the evolution of Johns' artistic mind over time.

COMPOST UTILIZATION GOES THROUGH THE ROOF

Center for Green Roof Research at Penn State University uses compost in its media studies and plans to explore microbial communities.

AT the Penn State Center for Green Roof Research in University Park, Pennsylvania, horticulturalists, plant physiologists and agricultural engineers are collaborating to study the many aspects of green roofs and their effects on the environment. From looking at broad questions of how green roofs mitigate storm water runoff to specifics in terms of modeling the evapotranspiration rates in these systems, the Center is dedicated to providing scientific answers for this fast growing sector of green technology. Fortunately for compost producers, the use of organic materials in this technology is proving essential.

A green roof can be either intensive or extensive based on the degree of maintenance required to grow plants in specially formulated green roof manufactured soils or "media" as it is often referred to in the industry. Intensive green roofs require a high degree of maintenance and can be thought of as "roof gardens". Media depths range from approximately 18 to 213 cm (7-84 inches) depending on the plant species used. Typically media depth must be greater than 25 cm (approximately 10 inches) to support an array of plant life in these systems. The additional roof load capacity needed to support such media depths is between 300 - 1,500 kg/m^sup 2^ (approximately 60-300 lbs/ft^sup 2^ or psf; pounds per square foot) depending on a number of factors such as the slope of the roof, type of manufactured soil used, whether or not irrigation systems are installed, and human traffic calculations. For comparison, typical single family homes in mild climate regions of the U.S. have additional roof load capacities between 10 and 30 psf. An intensive green roof system would not be appropriate for these types of roof structures without significant structural adjustments.

In contrast, an extensive green roof system typically requires a media depth of only 5 to 20 cm (approximately 2-8 inches) and is more functional in nature compared to an intensive green roof system; functional in the sense that its primary focus is for implementation as a Best Management Practice or BMP for storm water management. Additional roof load capacity needed for an extensive green roof system varies between 90 and 250 kg/m^sup 2^ (approximately 16-50 psf) depending on the same factors as outlined above for intensive systems). The studies carried out at Penn State all involve extensive green roof systems. It should be noted that load capacity ranges are generalized. Each green roof installation is unique and structural engineers should be consulted for the final load and design requirements.

HISTORY OF THE CENTER

The Center for Green Roof Research at Penn State began as an idea formed during a European trip that the Center's former director, Dr. David Beattie, an associate professor of Horticulture, took in the late 1990s. At the time, green roofs were not well known in North America despite over a century of usage in several European countries, mainly Germany. A car bumper manufacturer based in Malvern, Pennsylvania provided a much needed catalyst. JSP International Inc. approached Beattie and his colleague, current Center Director Dr. Robert Berghage, also an associate professor in horticulture, about additional markets for their porous expanded polypropylene or PEPP compressed plastic mats.

One possible application was as a layer in a built up green roof. Beattie and Berghage looked at two different species of plants, a sedum and a grass, planted in various mixtures of manufactured soils using the PEPP. Comparing temperatures on a conventional plastic sheeted roof, a gravel covered roof, and a green roof, they discovered just how well the green roof system did in terms of mitigating heat effects. During the summer of 2000 with an ambient temperature of 88�F, the temperature in the green roof media was 82�F. The plastic sheeting and gravel roof measured 140 and 118�F, respectively. In terms of the plant species used in the green roof system, sedum performed better than grass in terms of its ability to weather temperature and moisture extremes. Sedum, a relative of the cactus, grows low to the ground and doesn't shed much dead plant material. It also requires very little in the way of maintenance and nutrient requirements.

Because of the success of the initial partnership with JSP International Inc., the Center was able to obtain funding from other sources such as American Hydrotech and Carlisle SynTec, two green roof industry giants, and state and federal sources like the Pennsylvania Department of Environmental Protection (DEP) and the U.S. Environmental Protection Agency (EPA), respectively. The Center officially began in 2001 with a research site at the Russell E. Larson Agricultural Research Center in Rock Springs, PA, and a mission to demonstrate and promote green roof research, education, and technology transfer in the Northeastern U.S. The Center has become a leader in studying various media suitable for growing extensive green roof plants as well as providing quantifiable data necessary to answer critical questions about the effectiveness of green roofs in mitigating runoff from storm water events.

RECENT RESEARCH PROJECTS

One of the first studies carried out at the Center, and part of a master's thesis project by Julia (DeNardo) Hunt, a former graduate student in Agricultural and Biological Engineering (ABE), was an investigation into the mitigation effects green roofs have on storm water runoff. Dr. Albert Jarrett, a professor of Agricultural Engineering, was DeNardo's major advisor and supervised the study along with Beattie and Berghage. The research quantified the importance of green roofs in attenuating or reducing runoff. According to Jarrett, "The benefits of green roofs in attenuating storm water runoff are clearest if one looks at four things: 1) runoff volume reduction, 2) peak runoff rate reduction, 3) overall runoff delay, and 4) peak runoff delay in these systems." To look at these four variables, six buildings (4.65 m^sup 2^; 48 ft^sup 2^) were constructed; three with extensive green roof systems and three with conventional, standard asphalt roofs both with roof slopes of 1:12 (Figure 1). Each extensive green roof system consisted of a waterproof membrane and root barrier, a drainage layer, growth media, and vegetation (Figure 2).

The growth media had a depth of 7.8 cm (approximately 3 in.) and consisted of 12.5 percent sphagnum peat moss, 12.5 percent coir (coconut fiber), 15 percent perlite, and 60 percent hydrolite for a 75 percent mineral or inorganic material to 25 percent organic material ratio (v/v). Above the growth media was a 2.5 cm (1 in.) thick layer of PEPP into which vegetation (Sedum spurium) was transplanted.

The buildings at the Center for Green Roof Research had their own storm water collection systems installed complete with gutters, downspouts, and collection barrels.

The first event occurred on October 25, 2002, producing a cumulative rainfall total of 2.39 cm (.94 in). Green roof runoff total measured 1.93 cm (.76 in) for a runoff volume reduction of 0.46 cm (0.18 in) or 19 percent. The maximum rainfall intensity was measured at 6.6 mm/hr (0.26 in/hr) while the maximum runoff rate from the green roof was 4.1 mm/hr (0.16 in/hr) for an intensity reduction of 38 percent. In terms of delays, runoff from the green roof took 4 hours to begin and 1 hour from the time peak rainfall intensity was recorded to the time peak runoff occurred. Evidence such as this gives storm water engineers valuable information in planning storm water infrastructure for urban and suburban areas. Extra time to absolve rainfall events in these areas is critical to managing water quality and adds to the attractiveness of using green roof technology as a Best Management Practice or BMP in construction.

Other key findings from DeNardo's study were: 1) green roofs retained on average 6.5 mm (.26 in.) or approximately 45 percent of total rainfall during the period of study (two months), 2) peak runoff rates averaged 2.4 mm/hr (.09 in/hr) or 56 percent of the peak rainfall intensity, and 3) runoff from green roofs was delayed an average of 5.7 hours.

Jarrett has since expanded on DeNardo's work developing models for the way green roofs respond in two typical storm water scenarios: extreme storm events and cumulative annual rainfall. "Understanding how green roofs can help us manage storm water begins by looking closely at these additional elements," Jarrett comments. Two-year (2.6 in/day) and 100-year (5.3 in/day) extreme rain events were simulated. In addition, Jarrett used weather data from State College, PA for a 27 year period (1976 to 2003) to simulate how well a green roof would reduce the cumulative annual rainfall (mean annual rainfall = 40.3 inches). Results of Jarrett's modeling work showed that with a 2 year storm event in July with 5 dry days prior to the storm, green roofs could reduce the peak intensity of the runoff by 85 percent (compared to no green roof) and the volume of runoff by 61 percent. The 100 year rain event also in July and also with 5 dry days prior could reduce peak intensity of runoff by 60 percent and volume by 30 percent. Numbers such as these are the lifeblood of making technologies such as green roofs an attractive alternative to conventional storm water management strategies.

Other studies have followed and helped answer other critical research questions. Berghage and Beattie were interested in media depths and how different green roof plants might respond in these systems with varying drought situations. Christine Thuring, a former graduate student in the Department of Horticulture, with both Beattie and Berghage acting as her coadvisors, used this interest as part of her master's thesis project to investigate a suite of popular green roof plants grown in different types of media at varying depths and in different drought regimes. As mentioned above, plants in an extensive green roof system can be exposed to extreme temperatures and moisture levels. As extensive green roof systems are less deep than intensive systems, there is a tradeoff between using deeper media to conserve plant available water during these extremes and adding weight to the roof structure and hence cost to the project. Thuring's project looked at how five different plant species (Sedum album, S. sexangulare, Delosperma nubigenum, Dianthus deltoides, and Petrorhagia saxifraga) responded (when grown) in three different depths (3, 6, and 12 cm) of two different media (expanded shale and clay) in two different types of drought situations responded.

SWITCH TO COMPOST

The growth media for Thuring's study consisted of either 85 percent (by volume) expanded clay or shale as the mineral component and 15 percent (by volume) pelletized spent mushroom compost from Laurel Valley Soils in Avondale, PA as the organic component. The switch to composted organic material from sphagnum peat moss and coir fiber in the previous study was made to make use of a recycled waste product, spent mushroom compost, and promote sustainability issues in the region. Thuring adds that "compost usage in green roof media from a sustainability perspective makes a lot of sense and should be integrally tied to the makeup of green roof media mixes. Specifically, research in the area of water retention and the decomposition process by different composts as potential components of green roof media would be extremely beneficial." Echoing Thuring's comments, Charles Friedrich, a licensed landscape architect for Carolina Stalite Company, in a paper presented at the Greening Rooftops For Sustainable Communities in Washington, DC last year, stated that compost "is a preferred source for the organic component in green roof system media because of its high nutrient and microbial count, and it is politically correct because of its recycling value." However, he adds, "Care must be taken when selecting the source of compost; proper stability/maturity, particle size, and feedstock source of the product should be considered."

The two inorganic substrates in Thuring's study were used because of their popularity in North American green roofs and do not reflect the Center's promotion of one over the other. Thuring notes that "locally available inorganic materials from regional tile or brick manufacturers can minimize transportation costs and provide ecologically sound choices in terms of green roof media." All experiments were carried out in a 4 ? 30 m polyethylene greenhouse tunnel with all media placed in propagation flats modified to achieve the desired depth requirements. Air circulation, temperature, and irrigation were monitored and regulated throughout the study.

Key findings from Thuring's study were: 1) media depth most affected the growth of all plants, 2) herbaceous species did not survive in 3 cm (1.2 in) depths of either media, nor in 6cm expanded shale when subjected to drought conditions, 3) plant growth under drought was better in the clay compared to the shale, and 4), irrigation in the first weeks after planting is beneficial for plant establishment and performance. Indeed, initial irrigation proved vital for the herbaceous taxa and valuable for long-term performance by the succulents (not including S. album). In terms of design implications, Thuring's study showed that media depth and type, as well as water availability, are important considerations when selecting species for extensive green roofs. Succulent species performed well in 6 cm (2.4 in.) media, but always did better in clay versus shale. As for herbaceous species, green roof media depth should exceed 6 cm (2.4 in.), however more research on the use of such plants, especially native species, is needed.

CURRENT AND FUTURE STUDIES AT THE CENTER

Dr. Shazia Husain, a plant physiologist and visiting doctoral scholar, has begun experiments that expand upon the knowledge gained by previous research described above. Specifically, Husain has three areas of focus; elucidating mechanisms of evapotranspiration in green roof plants, determining plant responses to various mixtures and particle sizes of inorganic substrates and compost, and investigating potential ozone effects on green roof plants.

Using lysimeters with temperature and moisture sensors attached, Husain is working to quantify evapotranspiraton rates in Crassulacean Acid Metabolism plants or CAM for short. Husain states, "These plants, mostly succulents, have stomates that open and close during different times of the day to maximize water retention and minimize water loss. Knowing the mechanisms that are involved with these CAM plants can help scientists understand more about which plants are best suited for green roof systems and how they function to attenuate storm water runoff." In addition to studying the CAM mechanisms in these systems, acid buffering capacity, pH, electrical conductance, and nitrate levels are being monitored.

As there are numerous inorganic substances marketed for use in green roof media with equally numerous claims for their respective products' superiority, Husain is performing work on various expanded shales and clays of differing particle sizes. Additionally, Husain states, "Mixing these inorganics with organics such as compost is critical to rapid establishment of green roof vegetation. Approximately 20 percent organic material and 80 percent inorganic appears to be the best mix in terms of plant growth response to date," Husain continues, but she cautions against hard and fast volumetric percentage recommendations. "Each system is unique and the goal of each green roof system must be considered."

Husain is also working on the effects of ozone on green roof plants. While largely an unknown area of research in terms of green roofs, Husain hopes to build upon what is known about ozone formation and apply it to this "green" technology. According to the U.S. Environmental Protection Agency (EPA), ozone occurs in urban areas where expansive concrete, lack of vegetation, and fossil fuel burning are prevalent contributing to a ground level formation of ozone and localized temperature increases known as "heat islands". Heat islands can affect vegetation growing in urban areas interfering with plants' abilities to grow and store food. The use of green roof technology has been suggested as a way to mitigate the effects of heat islands in metropolitan cities, but the mechanisms involved in how green roofs do this are still not completely understood.

Ozone (O^sub 3^) is a colorless gas with a pungent odor. It's found in two layers of the atmosphere, the stratosphere and the troposphere. In the stratosphere, ozone provides a protective layer shielding the Earth from ultraviolet radiation's potentially harmful health effects. At ground level (the troposphere), ozone is a pollutant and contributes to the formation of smog (from www.epa.gov). Husain has proposed a number of experiments to look at the extreme effects of ozone on green roof plants to better understand how atmospheric conditions can be benefited by as well as cause harm to green roof systems.

In terms of future studies at the Center, a recent PhD candidate in Horticulture with experience performing bioremediation projects around the world has expressed interest in investigating the microbial community assemblages in green roof media. Nutrient cycling issues as well as the implications for green roofs to act as potential pollution treatment systems are anticipated as areas of exploration.

RECENT DEVELOPMENTS

The Center just received additional funding from American Hydrotech in September of 2005. This funding has enabled the Center to effectively double its data gathering capacity at the Rock Springs research site. Known as the HB (Hydrotech Building), its roof now boasts two 1:12 slopes, one facing north and the other south, with an effective roof area of 27.9 m^sup 2^ (288 ft^sup 2^), equal to all of the original six buildings' roof areas combined.

In the final analysis according to Berghage, "Green roofs are an excellent technology for use in rural, suburban, and urban areas where attenuating storm water runoff is critical. Green roofs are aesthetically pleasing, and there is strong evidence that they effectively mitigate storm water runoff and heat island effects in large metropolitan areas." But, Berghage adds, "in the U.S., regulatory agencies are sometimes slow to adapting new technologies and 'hard numbers' are necessary to make these same regulatory agencies take notice. Quantity right now in terms of how much green roofs can store and delay storm water and storm water runoff, respectively, is the driver for research in this area for the foreseeable future."

The Center for Green Roof Research has come far in its short five year history. From an idea that started across the Atlantic to the reality of a research center located in central Pennsylvania, scientific curiosity is a powerful force. Thankfully, with scientists like Beattie and Berghage, who carried out the first experiments at the Center before it was officially called a "Center", their collective curiosity appears to have been in large supply. And with engineering expertise from Jarrett, "hard numbers" were generated early to provide the quantification necessary to show green roofs could adequately mitigate storm water runoff. Graduate students have also proven to be an essential part of the Center's success with DeNardo, Thuring, and Rezaei answering essential and fundamental questions about this relatively new green technology in their theses. Husain's role as a plant physiologist at the Center will undoubtedly shed more light on the mechanisms of how plants in these systems work to slow storm water runoff as well as other benefits. The Center appears to be on a mission with a team of scientists dedicated to generating results that are going through the roof.

US governor signs budget, ends state shutdown

ST. PAUL, Minnesota (AP) — Minnesota Gov. Mark Dayton has signed a new budget that ends America's longest state government shutdown in the past decade.

Dayton's signature came Wednesday after lawmakers met in special session starting Tuesday afternoon to give their own approval to the deal. All sides formalized an agreement that Dayton struck with leading Republicans late last week.

The two sides argued bitterly over taxes and spending for months. When government shut down July 1, it closed state parks and rest stops, laid off 22,000 state employees, stopped road projects and much more.

The end to the shutdown began when Dayton moved last week to accept a borrowing plan offered by the Republican shortly before the stoppage began.

The process involves empowering with the skills, attitudes and knowledge to create a safe world and build a sustainable environment. The philosophy teaches nonviolence, love, compassion and reverence for all life. Peace education confronts indirectly the forms of violence that dominate society by teaching about its causes and providing knowledge of alternatives. (Harris & Morrison, 2003, p. 9)

This definition of peace education by one of the field's leading author teams provides evidence of the close alignment of principles behind peace and global education, as it is termed in North America. Other popular sources on global education at the school level also emphasize the importance of peace education (Goldstein & Selby, 2000). Both collections define peacemaking as mainly an interpersonal experience, resulting in personal conflict, racism, gender and sexual exclusions, and environmental degradation. The focus is placed on the local and the personal, rather than the international, despite ongoing concern with what Galtung (1975) called structural violence. This waning of interest in the school curriculum in the international and structural dimensions of peace studies rather than the personal uses of peace-making has clear instrumental value for the classroom and schoolyard. However, the general effect of narrowing peace education's focus to the local has been to further marginalize it. In fact, it has been persuasively argued that school-based peace education struggles for legitimacy even within its own field: peace education vs. peace research; knowledge vs. praxis of peace education (Burns, 1996). Aspeslagh (1996) notes that peace education is "condemned to the waiting room of society," where the only thing left for its proponents is to "tap at the window looking into education and the public, hoping to attract some attention" (p. 392). Not all researchers in this field would agree with Aspeslagh's assessment, but most would acknowledge the fluid relationship between peace and global education in the school system, and the difficulties of peace education to find its place. On the other hand, global education, the larger framework into which peace education is now commonly inserted, has much more often developed a broad, international scope with local applications. The relationship between peace and global education was not always defined in this way. In fact, peace education has a deeper history than does global education, having developed a pedagogy with distinctive qualities, and has provided a means for women to exercise a public role long before they were accorded civic rights through the franchise.

PURPOSE AND METHOD

This article reports on research that surveyed the literature on peace and global education for secondary schools. The goal was to explore the historical analysis and position of self-defined peace education within the broader global education field. Peace and global education were considered both for their spatial and discursive positions. We1 surveyed all available literature on peace, and what has come to be termed global education, from the 1970s to about 2000. In so doing, we created a database of materials on peace and global education for Canada, the United States, and Britain. This literature included articles in professsional and peer-reviewed periodicals, articles in published collections, monographs, and textbooks intended for classroom use. In all these secondary sources, the relative space devoted to, and the importance of peace education was weighed against the other strands in global education.2 This article reports on the results of the investigation into the literature supporting peace and global education in the United States, Britain, and Canada. It offers a brief history of peace and global education and presents conclusions reached. It argues that as a field, school-based global education has progressively redefined itself, broadening its scope each time. On the other hand, school-based peace education has narrowed. Recast in ever more personal terms, peace education is less likely to engage the structural sources of systemic inequities and violence.

PEACE EDUCATION DEFINED THROUGH THE LITERATURE - PAST AND PRESENT

As with the global education movement (most researchers agree peace education has become a part of global education), current school-based peace education encompasses a wide variety of aims and approaches, depending on the audience and socio-political and ideological context. And like global education, too, peace education overlaps and shares theoretical and practical ground with other types of "progressive educations" (Toh & Floresca-Cawagas, 2000, p. 368). These include development education, environmental, human rights, and multi-cultural education. Hicks (1988) notes that peace education shares a concern of contemporary problems with global education as the basis of its content and a belief in participatory and active learning strategies (see also Perkins, 2002). Hicks (1988) also distinguish between negative and positive peace, as well as direct and indirect (structural) violence (Galtung, 1975). Peace education has been identified as sharing common ground with citizenship education through beliefs in the interdependency of the world's citizens (Harris, 2002; Toh & Floresca-Cawagas, 2000), and through its faith in tolerance, respect for difference, and an appreciation of the rights of others as productive of peace (Mahrouse, 2006).

Within these shared frameworks, therefore, peace education has been defined as education that promotes concepts of non-violence, human rights, social justice, world-mindedness, ecological balance, meaningful participation, and personal peace (Carson & Lange,1997; Hicks, 2004). Others define peace as all those times when a nation is not actively at war, and peace education as everything supporting that condition (Thompson, 1987, p. 29). In Peace Education, an important source on this topic, Harris and Morrison (2003), who define the field as comprised of diversity education, violence-prevention, conflict resolution, and civic education, propose attacking violence on three levels: peace-keeping, peacemaking, and peace-building (p. 11). Reardon (1993, 1996, 2001) defines peace education as supported through a culture of peace at home and abroad. Hers is one of the few definitions to build a feminist perspective into her analysis.3 Finally, human rights and disarmament education figure prominently in some models of peace education (Roche, 2003).

Aside from definitions including disarmament and perhaps human rights, the burden of these definitions falls on the side of personally experienced conflict management. To explore but one of the justifications for peace education, that of Harris and Morrison (2003), peacekeeping is argued to be important "to create an orderly learning climate in schools" (p. 11), while peacemaking can often result in conflict resolution. Peacebuilding strategies, although too rarely engaged, should "create in children's minds a desire to learn how non-violence can provide the basis for a just and sustainable future" (Harris & Morrison, 2003, p. 11). As important as all these approaches to violence-prevention and management undoubtedly are, few encourage an examination of social or economic structures and the failures within these that create inequities. Thus, the meaning of peace education has become for many a form of community safety. Peace education is currently focused on anti-bullying and conflict resolution strategies (Harris & Morrison, 2003; Holden, 2000; Toh & Floresca- Cawagas, 2000). Beyond this relatively narrow, personally experienced programme, peace education in schools has been judged to be in sharp decline (Holden, 2000; Toh & Floresca-Cawagas, 2000).

The contemporary peace education movement dates from the late nineteenth century when peace societies in Europe and North America encouraged internationalism through educational programmes. Founded in 1901, the Societ� d'�ducation Pacifique set out to create a network of teachers who would incorporate peace into the curriculum. Peace societies appeared in France, Italy, Germany, Belgium, Britain, and Scandinavia. Most had the objective of educating youth to the dangers of the international system and suggesting alternatives (Cooper, 1987). In North America, peace organizations adopted an analysis of violence as rooted in both individual actions and systemic societal failures, and as changeable through education (Boutilier, 1988; Crowley, 1980; Williamson & Gorham, 1989).

By the First World War, an international network of both women's and gender-integrated peace groups had been established, and these too ultimately depended on education to further their principles. To chart women's particular involvement, the International League for Peace and Freedom (Boutilier, 1988; Cambridge Women's Peace Collective, 1984; Page, 1972; Pierson, 1987; Vellacott, 1987), the Woman's Peace Party (Degen, 1972; Gorham, 1987), and the 1915 International Conference of Women for Permanent Peace (Costin,1982; Gorham, 1987; Vellacott, 1988) all turned to education as a critical force for change (Toh & Floresca- Cawagas, 2000). In many cases, these international associations also worked through national groups promoted by women and men to lobby for peace education, such as the American School Peace League (Toh & Floresca-Cawagas, 2000), the Canadian League of Nations Society (Strong-Boag, 1987), the 1932 Disarmament Conference, which promoted moral disarmament, and the International Peace Committee, which approached peace through action-oriented methods (Burns & Aspeslagh, 1996). As noted by Strong-Boag (1987):

For all their differences, internationally-minded women of many persuasions shared both a conception of their sex's particular sensitivity to the costs of armed conflict and an essential optimism about the power of education and the limitations of prejudice. By instructing children and adults in the follies of war and the ways of peace, women could prepare the way, as surely as any diplomat, for a better world. (pp. 171-172)

But this is not to say that men were uninterested in peace education. Both men and women widely recognized that education was an important vehicle for encouraging peace (Burns & Aspeslagh, 1996; Cumming, 2001).

Peace societies for much of the past century have depended on education to alert young and old, men and women, to the international structures and systemic inequities that encourage militarism and discourage peaceful solutions. Peace education was understood to be furthered through international cooperation, and by a pedagogy that emphasized active global citizenship. Central to this pedagogy are (a) values clarification and values analysis (Reardon, 1996), (b) critical thinking strategies to uncover assumptions rooted in racism, patriarchy, and postcolonialist structures, (c) the development of an ethic of caring for others, the environment, and structures supporting justice (Toh & Floresca- Cawagas, 2000), and (d) skills associated directly with conflict management and resolution (Harris & Morrison, 2003). Despite its promising history as a separate area of study, however, by the 1970s peace education was been incorporated into the broader rubric of global education (Hanvey, 1975), to which the article now turns.

GLOBAL EDUCATION AND GLOBAL PEDAGOGY DEFINED IN THE LITERATURE

Almost from its inception in the 1970s, the reach of school-based global education (as it is termed in North America) covered a lot of territory, both in terms of the content and perspective it urged students to adopt. It is generally accepted that the first articulation of the field was offered in the 1970s by Hanvey in the United States and by the World Studies Project in Britain. Hanvey (1975) set out five elements of global education:

1. perspective consciousness in which individuals hold views, often unconsciously, according to our own cultural framework;

2. knowledge of world conditions including economic patterns, population growth and movement, natural resources and use, science and technology, political movements, law, health and security and peace;

3. cross-cultural awareness of the world's diverse value systems and societal frameworks;

4. global systems dynamics including economic, political, ecological and social systems; and

5. knowledge of choices or alternatives to current management patterns, including foreign aid, consumption patterns and security systems.

Heater, in 1980, outlined the needs of a World Studies course in Britain. A few years later, Kniep (1986) redefined the field in America, distinguishing four features:

1. the study of human values, especially those that are universal rather than particular to a region or nation;

2. global systems including economic, political, ecological and technological;

3. global issues and problems emphasizing persistent, transnational, and interconnected problems of security systems, the environment, and human rights;

4. global history in which the sources of both universal and particularist human values and experiences would be engaged (see also Tucker & Cistone, 1991).

In these foundational definitions of global education, peace was defined in terms of interlocking global systems buttressed by cultural values, and occupying an important place.

Since these early renderings, there has been much reordering and updating in response to new challenges, and quiet jettisoning of features of global education that have proved to be especially difficult to act upon or as threatening to divide a delicately constructed and maintained community. Case (1993) proposed a strengthening of the "perceptual dimension" towards increasing open-mindedness, anticipation of complexity and empathy, and resistance to stereotyping and chauvinism in understanding and decision making. In comparing various national definitions, Pike (2000) argued for "common threads" (p. 65): (a) the interdependence of all people within a global system, (b) the connectedness and diversity of universal human attributes, values and knowledge, curriculum subjects, aspects of schooling, humans and their environment, and (c) the privileging of multiple perspectives before reaching a view. Blackburn (1988) and Lamy (1987) identified the importance of the role of nongovernmental organization in global economic and educational systems and Bigelow and Peterson (2002) noted the continued record of social injustice. In addition, the importance of indigenous peoples' views (Lamy, 1987) and the emphasis of holism over particularism (Kolker, Ustinova, McEneaney, 1998) have also been forwarded as themes within global education since the late 1980s. In her synthesis of the literature by end of the twentieth century, Merryfield (1997) added the importance of analytical, evaluative, and participatory skills in private and public life (see also Kirkwood, 2001; Lapayese, 2003; Willinsky, 2005). During this period as well, anti-racism (Merryfield & Subedi, 2001) and multiculturalism (Toh, 1993; Zachariah, 1993) became strong features of global education.

Several characteristics of this burdened definition are noteworthy. First, the parameters of global education are so diffuse, and the objectives so grand, that the field has been criticized for conceptual imprecision (Lamy, 1987). Case (1993) noted that global education operates as an educational slogan rather than as a coherent framework, "a positive emotive label that creates a unity of feeling and spirit about the tasks to be confronted by schooling" (Popewitz, 1980, p. 304, as cited in Case, 1993). Although some global educators welcome the freedom to shape global education to the diversity of students' and regional interests (Lapayese, 2003; Le Roux, 2001), others argue that this much-decried "wishy-washy" nature of global education must be clarified, and that failure to do so could easily hasten withdrawal of support for its many laudable goals (Case, 1993). Second, in comparison with the founding statements, the successive redefinitions of global education at best subsume peace within discussions of value systems or multiple perspectives. However, this is not to suggest that peace and global education are at odds: the compatibility of the two strands were clear into the late 1980s when Reardon published companion volumes in the same year on global and peace education (Reardon, 1988a, 1988b) and Pike and Selby (1988) could include Peace and Conflict as one of seven objectives for global education.4 But since that time, with a few major exceptions, peace education as a separate but interconnected topic within global education has received less and less attention (Burns, 1996).

Pedagogically, global education bears testimony to its social activist and progressive roots. It arose at the same time as experiential learning and values clarification, open schools, and child-centred education (Hendrix, 1998). Part of this tradition has been the claim that content and process should be fused or at least interdependent (Le Roux, 2001). As the field has developed, strategies have emerged to encourage activitybased learning (Selby & Pike, 2000) and especially perspectivistic analysis (Pike & Selby, 1988; Teach Magazine, 2005), cooperative learning and role-playing (Holden, 2000), story-telling (Calder, 2000; Moore, 2003), simulations (Gautier & Rebich, 2005), student projects and community surveys, (Tye & Tye, 1993) community service (Willinsky, 2005), and web-based research (Risinger, 1998). New app roaches to assessment encompass cognitive, affective, and participatory domains (Diaz, Massialas, Xanthopoulos, 1999). At its most radical, strategies rooted in post-modernism and the democratic pedagogy of Aronowitz and Giroux (1991) stressing power differentials, the disabling authority of hegemonic structures, as well as the possibilities of empowering discourse (Preece, 2002; Wells, 1996) have offered much-needed emancipatory approaches to give the field renewed direction and edge.

GLOBAL EDUCATION IN THREE SITES

The literature survey carried out for this study illustrates both the distinctive forms of global education in specific national settings and the process by which peace education has been nudged to the margins. Further, the literature showed that national preoccupations have caused certain themes to be dropped in some sites from the global educational agenda (more commonly termed "world studies" in Britain), and others to be added. In all cases, however, the literature survey demonstrates that the peace constituent has become increasingly diminished. The implications of this loss are more than cosmetic; rather, they are fundamental to the issues considered important in global and peace education, and are important to the teachers and students of global education, and to society generally.

The American Case

However one defines the field of global education, Sutton (1999) asserts that its origins are found in post-World War II American experiences. Exposed to other national and ethnic combatants and world views, the loss of European colonial control, and the bracing effect of Allied military might, the United States developed markedly more interest in the international community and in the 1950s encouraged international education for its school children. Despite the challenges of McCarthy-era anti-communism and the competitiveness sparked by Sputnik for educators seeking a more internationalist focus, the communist and scientific threats also encouraged learning about the world on the principle, "know thy enemy" (Sutton, 1999, p. 10). American support for the fledgling United Nations and its specialized agencies, particularly the United Nations Educational, Scientific, and Cultural Organization (UNESCO) with its dissemination of teaching materials in favour of worldmindedness, also profiled peacemaking as a worthy topic in Social Studies and Civics courses. The horrific bombing of Nagasaki and Hiroshima brought a new urgency to demands for disarmament, a movement that continues today (Toh & Floresca-Cawagas, 2000).

Hendrix (1998) points to the important stimulus of the 1963 Second World Food Congress in Washington, D.C. for American global education. Hosted by President Kennedy, the conference positioned the United States as a leader in ending global hunger and poverty and emphasized the role of education in preparing a populace able and willing to participate in the campaign. By the late 1960s, the American Civil Rights movement, the protest against the war in Vietnam, the student riots at Kent State, the race riots in Detroit, McLuhan's notion of the "global village," and the second-wave women's movement all encouraged the reconsideration of old certainties. "International education," which referred to area studies, languages, and "hot" international topics, (Bruce, Podemski, & Anderson, 1991) became more "global" with the report by Becker and Anderson's (1969), An Examination of Objectives, Needs, and Priorities in International Education in United States Secondary Schools. Commissioned by the U.S. Office of Education, the report's main arguments found expression and support in a wide variety of official documents and monographs, including most importantly, Hanvey's (1975) An Attainable Global Perspective. As noted, Hanvey's re-articulation of internationalist into global education provided the first blueprint for this new curriculum area in North America.

Hanvey's (1975) analysis stressed an apolitical, ecologically inspired, culturally relativistic order. The perspective of the learner was as a neutral world citizen, not as one constituted with race, ethnic, class, or even gendered qualities. If national divisions were to be ignored as much as possible, so were differences created by biology, history, or culture. This perspective included progress towards peace that was rooted in national and even international crises. This ahistorical view fit easily with progressive educational pedagogy in which child-centredness trumped national educational prescriptions. Hence, with the release of the report, A Nation at Risk: The Imperative for Educational Reform (1983), in which academic excellence was proposed "to foster economic competitiveness" (National Commission on Excellence in Education), rather than global understanding and tolerance, proponents of global education found their ability to fit into the new paradigm limited. Post-Hanvey prescriptions for global education did little to quell a rising tide of criticism. Cunningham's 1986 report for the Federal Department of Education, Blowing the Whistle on 'Global Education,' alleged that global educators "indoctrinated" children with pacifism in the face of Soviet threats, "moral relativism," "free-market economics," and "redistribution" of wealth to the developing world (as cited in Sutton, 1999, p. 21). The influential Readers' Digest, which took particular exception to global education's promotion of "pacifism" (Ryerson, 1987), called into question the peace component of global education. By the late 1980s, Secretary of Education Bennett (1989) surveyed six global education textbooks and curriculum materials, finding their approach both "relativistic" and "anti-rational." Ravitch (1989) wondered if American students exposed to global education should be "encouraged to accept political, social, and economic systems and behaviors in other countries uncritically" (p. 3) or encouraged to apply the same critical standards to global education as to their own national history. Others questioned priorities and implementation strategies in times of financial constraint and evaluation methods.

Once a brave new field of holistic education dedicated to better understanding the world and its cultures, global education was accused of being witlessly uncritical, amorphous, and even un-American. Peace education in particular came to be seen as unpatriotic (Harris & Morrison, 2003, p. 166) as somehow siding with America's many enemies by poisoning children's minds. Assertions of this magnitude were not easily thrown off, and the result was for global educators to avoid controversy, and seek balance. One way to achieve balance was to reduce divisive discourse, including that which encouraged peace. What was recommended, Tye (2003b) avers, was teaching "about other peoples and countries, but do[ing] it 'patriotically'" (p. 165).

To buttress the field, global educators have made the connection of global education to school reform, claiming the general reform orientation of global education as an indication of its general utility to all who have a stake in the American educational system (Haakenson, Savukova & Mason, 1998-1999; Harris, 2002; Kolker, Ustinova, & McEneaney, 1998- 1999). But despite such attempts to find a route back into mainstream educational discourse, global education has never fully recovered its status in the United States. Since the attacks of September 11, 2001, and the War in Iraq, peace education, especially, has been at low ebb (Westheimer, 2007).

The British Case

Similar emancipatory echoes, as in the American context, influenced the global education movement in Britain, featuring the construction of Palestine and struggles in South-east Asia, idealism of the post-colonial Commonwealth and United Nations, and the slow but gradual recovery of Europe and Britain herself after the Second World War. The Council for Education in World Citizenship, established in 1939, provided firm ground for the development in the 1960s of the world studies movement (Heater, 1980.) In the late 1960s and 1970s, world studies fused the active learning movement of Rogers and Bruner (World Studies Project, 1976) with the social activism of Freire into a holistic, if informal, model promoting "knowledge, attitudes and skills that are relevant to living responsibly in a multi-cultural and interdependent world" (Fisher & Hicks, 1985, p. 8). In the same period, peace education made huge strides throughout the United Kingdom with system-wide changes in teacher education, in school organization (Toh & Floresca-Cawagas, 2000), and very importantly, in the curriculum which identified as important learning outcomes "peace and conflict, development, human rights and the environment" (Fisher & Hicks, 1985, p. 8). Key resources, such as Haavelsrud's (1976) Education for Peace: Reflection and Action and Hicks' (1988) Education for Peace helped to sustain the focus on peace education. As well, Heater's (2006) role in world studies provided essential leadership for the broader field, continuing even today with his championing of, in his words, "multiple citizenship." The Centre for Global Education (CGE) at York [St. John University] (Pike & Selby, 1988) is credited with maintaining the movement's momentum, as did the World Studies 8 - 13 Project in Lancaster.

Pedagogically, world studies became a model in its promotion of "experiential and participatory learning," including discussion, debate, reflection, and critical thinking (Hicks & Steiner, 1989). Other pedagogies favoured were small-group discussions and collaborative research, Brunerian- style problem-solving, role-play, and simulations, and the use of a broad range of cultural artifacts rather than print in the decision-making process (Holden, 2000). By the mid-1980s, over half the teachers in England and Wales were actively involved in world studies and many more used parts of the curricula and pedagogical approaches to supplement other curricula (Holden, 2000, p. 76). This included peace studies.

As in the American experience, the backlash began to gather strength from the early 1980s when global education was criticized for avoiding divisive political issues and power differentials (Mullard, 1982; Huckle, 1983). Self-esteem building and interpersonal cooperation were criticized for capturing too much attention and systemic inequities receiving too little attention (Steiner, 1992). The rich pedagogical approach came under attack as well, with claims that process overshadowed content (Lister, 1987). The implicit leftist ideology offended many (Scruton, 1985). Official unflattering assessments of the British world studies curriculum found their mark with the introduction of the National Curriculum (Department of Education, 1988). It defined 10 compulsory subjects with mandated knowledge, an Anglo-centric focus on the past rather than the future-orientation of most global education, and a centralized testing and evaluation component, with the results published and schools ranked. Whole-class instruction was recommended, disciplinary boundaries reinscribed, and authorized knowledge privileged over student-generated understandings. Content and pedagogy took a dramatic turn to the right, relatively marginalizing as well the strong programme of peace studies.

Long-range assessments suggest that teachers continued to use active learning pedagogies, especially those who learned their profession within the progressivist framework. However, issues such as peace and conflict, human rights contraventions, or racism and environmental education seem to have been cut back (Holden, 2000, p. 78). Further, the moral agency that underlay much of this approach to learning was at first side-stepped for academic excellence, and then reintroduced in the new citizenship curricula of 2002. Here, the pedagogical demands to create active citizens, able and willing to make informed and intelligent decisions about civic life and seeming to care about civic institutions, has recreated a space for the old strategies of debate, role play, and community- based research. What is missing, we found in this survey, and strikingly so, is much recognition of peace education as more than solving personal conflicts rather than systemic injustice. Where the American global education movement attempted to "hitch its cart" to the school reform horse, the British linked its reform to the new citizenship education. Learning to have "morally and socially responsible behavior" (QCA [Qualifications and Curriculum Authority], 1999, as cited in Holden, 2000, p. 77) was one of three primary goals of the new curriculum. Nevertheless, of all three countries, it could be argued that global education remains the strongest in the United Kingdom with new publications supporting theory and practice (Hicks & Holden, 2007).

The Canadian Case

It is a truism to assert that Canadian norms, educational and otherwise, owe much to both the American and British examples. So it is with the case of global education. Falling heir to both the reformist impulse of American civil rights, anti-racism, and feminism, and to the especially close alignment of women with the peace process found in both the United States and Britain, Canadian global education has developed as something of an amalgam of these national models, with strong links to the British.5 In fact, in both Canada and Britain, Pike (2000) asserts, peace education has traditionally ranked as a valued field. In this, it shares common ground with development, environmental, human rights, and multicultural education (p. 67).

The first expression in Canada of what would come to be called global education followed in the late 1960s and the early 1970s on the publication of a series of educational Royal Commission Reports of which the so-called Hall-Dennis Report (1969) in Ontario was the most influential (Gidney, 1999). Widely acclaimed for their championing of progressive education principles, including holistic rather than disciplinebased curricula, Brunerian discovery-based pedagogy, values clarification strategies, and resource-based research and decision making, the educational climate in most Canadian provinces in this era provided an accepting context for some version of global education, including peace education. Despite education being a provincial jurisdiction, by the 1970s there was an enormous expansion in the Federal Government's support for development aid and expertise through generous funding of the Canadian University Service Overseas (CUSO), the Pearson government's establishment of the Company of Young Canadians (CYC) and the Canadian International Development Agency (CIDA). By the 1980s, the latter group was funding global education, professional development centres across Canada, which in turn, placed effective pressure on provincial ministries of education to formally sanction global education topics in the mandated curriculum. Peace education also thrived; one observer described peace education as having "an almost evangelical fervor" in that period (Hargraves, 1997, p. 109). Inevitably, such enthusiasm also generated controversy.

As retrenchment occurred in Britain and the United States throughout the 1980s, so too did Canadian global education begin to lose ground by the mid-1990s, a period generally regarded as one of conservatism in Canadian education (Gidney, 1999). By 1995, most local professional development centres had been closed, and what global education remained was transferred to post-secondary institutions (Tye, 2003a, pp. 19-20). Even here, however, funding was tight and activity much reduced. Yet, the moral component of global education did find strong official support through the widespread recognition that schooling must support apparently flagging citizenship training (Gidney, 1999; Willinsky, 2005). Along with several other jurisdictions, Canadian provincial ministries of education identified character and citizenship training as goals for the new millennium, resulting in such developments as a separate Civics course in Ontario, launched in 1999. As global education had linked its programme in other places and times to school reform or citizenship training (Calder, 2000; Hendrix, 1998; Lapayese, 2003), so too in Canada, global educators sought to shore up sagging support by redefining global education as global citizenship (Reed, 1996). One result of this redefinition was the further marginalization of peace education, now transformed almost exclusively into conflict management and resolution in aid of citizenship skills (Toh & Floresca-Cawagas, 2000). Further, to criticize foreign policy in a post-9/11 world carries with it particular dangers. In a period of perceived vulnerability by many Western governments, peace talk, which is local rather than internationally positioned, is both more welcome, and in many ways, simpler for educational purposes (Cook, 2007). As well, peer pressures resulting in bullying is a major current preoccupation with most educational and many civic authorities, lending peace education as conflict resolution a renewed utility.

CONCLUSION

Peace education as personal violence prevention has a number of weaknesses. First, it tends to ignore or at least mute the structural roots of violence and war - to understand peace as a goal only for one classroom or school or community. This understanding results both in a more manageable problem, but also in one that is removed from its sources of persistent conflict, and only superficially open to resolution. Second, by narrowing the range to local community issues, the alliance between peace and global educational resources and personnel is weakened, with the field of peace education left isolated. Third, this pale and instrumental definition for peace studies has no apparent history or constituency beyond those who crave peace, and who among us does this not include?

Born in the radical 1970s, and tied to social and economic issues that surfaced in that decade, it should not be surprising that global education (or "world studies"), as a field, has remained under-theorized and heavily reliant on a political culture that has become increasingly less respectful and perhaps hostile to its fundamental principles. One way in which global education has struggled to survive in the face of growing demands for practical educational skills rather than global justice has been to regularly reinvent itself, jettisoning those elements that have the potential to weaken its political acceptability. But a global curriculum that takes on the divisive and most difficult issues - many of which are closely associated with the implications of peace and governance in conflict settings - would breathe new life into a field still struggling to find a place in the broader mainstream curriculum.

I want to underscore the fact that this article is concerned primarily with the nature and interrelationships of peace and global education in schools. At this level, peace education draws heavily from and is enriched by an increasingly robust post-secondary educational sector. This sector could, and I would argue, should influence peace and global education more at the school level in all three countries examined. These post-secondary programmes in peace studies typically combine interpersonal and structural conflict studies with international conflict resolution. The analysis and critique presented here does not apply to the postsecondary sector. However, a closer alignment of these two domains might well present a solution to the problems identified through this research. The sites were chosen because they represent different national and political systems as well as different educational systems. Nevertheless, the same general process has occurred in all three systems: peace education has incrementally lost ground to global education. Hence, a solution for one might well serve others well.

Having surveyed the literature on the history and current position of global and peace education in the United States, Britain, and Canada, it is clear that, although the specific national experience has differed to some degree in these settings, there has been a common experience of peace education's diminution in its uneasy relationship with global education or world studies. As educators survey a world rent by many of the same problems in evidence when the field first developed in the 1970s, and reflect on the capacity of the educational system to reinvigorate youth to fight as once their elders fought, we might reasonably hope that global education, with a strengthened peace education component within global education, could better inform this struggle than it is now capable of doing.
