An environmental life cycle optimization model for the European pulp and paper industry 总被引:1,自引:0,他引:1
Will paper recycling reduce the environmental impact of the European pulp and paper sector? If so, is maximal paper recycling the best policy to optimize the life cycle of the pulp and paper sector? We explore these questions using an approach that combines materials accounting methods and optimization techniques. Environmental impact data are inputs for a linear programming network flow model to find optimal configurations for the sector. These configurations consist of a mix of different pulping technologies, a geographical distribution of pulp and paper production, and a level of recycling consistent with the lowest environmental impacts. We use the model to analyse scenarios with different recycling strategies. Recycling offers a reduction in environmental impact in regions with a high population and a large production of paper and board products. Regions with a large production of graphic products should focus on cleaner virgin pulp production with energy recovery. We conclude that relocation of paper production also offers a reduction in environmental impact. However, the severe effects on the economy make this policy less attractive than a combination of recycling, cleaner pulp production and energy recovery. 相似文献

With the recent increase in social work leadership literature, a few issues in research and practice have come to light. Social work research employs leadership theory derived from military leadership principles adjusted for application in corporate entities, which have decidedly different goals and processes than social work organisations. These models may be influencing the methods of social work leadership research such that study outcomes reflect business-based rather than human service processes and goals. A dearth of leadership education in social work schools and in professional social work settings contributes to a paucity of social workers in upper level administrative roles. A systematic theoretical literature review on social work leadership is conducted in order to generate a working definition of social work leadership and a series of multi-level social work leadership principles. Implications for future research and practice are discussed. 相似文献

New data from a prevention curriculum project on officer-involved domestic violence reveals significant differences in the reported job stress of Florida's correctional officers when compared to police officers who took the same surveys. The significantly higher reported levels of organizational stress in particular—especially those related to staff and resource shortages and attitudes about leadership—raise concerns about the relationship between organizational stress and the reported drastic budget cuts, hiring freezes, and layoffs experienced by the Department of Corrections in 2009. The surprising disparity has significant implications for policy makers, who should be aware of the high cost of stress in officer health and well-being when making budgetary decisions about the state's rapidly increasing inmate population. 相似文献

This article evaluates how evolving social policies for very young children and their families affect the marginalisation of Roma children from mainstream Bulgarian society. The Roma (or 'gypsies') have long been ostracised by various societies and since the fall of communism in 1989 have become increasingly vulnerable to income poverty and social exclusion. The exclusion of Roma threatens Bulgaria's economic and political growth because the Roma constitute an increasing proportion of the population. The article compares the effects of current child and family policies on modifying the social and economic differences between very young Roma children under the age of three and those of majority Bulgarian children. It demonstrates how both universal social policies directed at helping all children and policies targeted on helping the most deprived children in a population, can, because of previous employment and other factors, further marginalise the most disadvantaged children in a population. 相似文献

AbstractObjective: A Haddon Matrix analysis was used to systematically review literature evaluating college campus sexual assault prevention programs to identify research gaps and intervention opportunities. Methods: Articles included were published from January 1, 2001 to December 31, 2017; indexed in PubMed, PsycInfo, or Scopus; involving English-speaking undergraduate students in the US; with experimental or quasi-experimental design. Results: All 31 eligible studies evaluated educational programing; all relied on self-report measures; and three-quarters had follow-up periods ≤ 6?months. Significant positive effects were reported by 6 of 10 studies that measured bystander behavior, 6 of 10 that educated potential victims and assessed victimization, and one of four that educated potential perpetrators and measured perpetration. Conclusion: The Haddon Matrix analysis identified the need for interventions that address perpetrators and the post-assault period, as well as studies of the impact of enforcing existing policies and new environmental and situational approaches to sexual assault prevention. 相似文献

This article provides experiential evidence on the transportability of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) screening tool and brief intervention in a mental health clinic. There is very little published information on implementing screening and brief intervention (SBI) in a mental health setting. Moreover, few SBI projects have reported on clinicians' experiences using the ASSIST. The article documents a successful attempt at implementing the ASSIST and discusses the benefits and challenges of doing SBI in a mental health setting. 相似文献

Those engaged in community‐based participatory research often comment on tensions between social scientific and community values, yet little systematic evidence exists about the relationship between social science research methodologies and community participation. We analyze nearly 500 peer‐reviewed articles published between 2005 and 2015 on Indigenous issues in Canada, where policies encourage participatory research methods with disempowered groups. We find that research that includes Indigenous participation is more likely to include Indigenous epistemologies and participatory evidence sources and analysis methods. We also find that peer‐reviewed research involving Indigenous participants often fails to go beyond minimum levels of consultation required by policies. 相似文献

Given global demographic and social trends, the need for new policy and program responses is essential. This article identifies and describes new and traditional social risks affecting children and their families in both industrialized and developing countries by region. Traditional risks continue in the developing as well as the industrialized countries but the extent and scale are very different and the problems are far more severe in developing countries. In addition, new risks are now evident and new policy responses are emerging. Attention to the new risks is increasing, with growing investment in services and policies facilitating the reconciliation of work and family life and non-traditional families. The citizens of many developing countries experience new risks as well, but their capacity to confront and address these risks is also more limited. 相似文献

Abstract This article introduces the idea of social defence, which is nonviolent community resistance to aggression as an alternative to military defence. An outline is given of some connections between the grassroots orientation to social defence and strands within community development. A community research project on telecommunications is described to illustrate the possible connections that can be forged between social defence and community empowerment. 相似文献
