Canada's Model Forests 20 years on: towards forest and community sustainability?

We review how Canadian Model Forests pursued forest and community sustainability over the course of two decades (1992–2012). Given its roots in the forest industry and forest science, Model Forest programming initially faced some challenges in pursuing the socio‐economic dimensions of sustainable forest management (SFM) in order to fulfil mandated community sustainability objectives. This was due, in part, to how objectives, stakeholders, and expertise were brought together to develop SFM. The programme helped to define sustainability and the SFM paradigm, advance forest science and social research, and bring together a mix of usually adversarial partners in the name of innovation. Ultimately, the termination of federal programming was linked to high‐level policy shifts, yet difficulty in delivering on the socio‐economic dimensions of SFM during a period of forest sector and community crisis was also a factor.     

Biosolids management strategies: an evaluation of energy production as an alternative to land application

Currently, more than half of the biosolids produced within the USA are land applied. Land application of biosolids introduces organic contaminants into the environment. There are potential ecological and human health risks associated with land application of biosolids. Biosolids may be used as a renewable energy source. Nutrients may be recovered from biosolids used for energy generation for use as fertilizer. The by-products of biosolids energy generation may be used beneficially in construction materials. It is recommended that energy generation replace land application as the leading biosolids management strategy.     

Psychosocial safety climate: Conceptual distinctiveness and effect on job demands and worker psychological health

Psychosocial safety climate is an emerging construct that refers to shared perceptions regarding policies, practices, and procedures for the protection of worker psychological health and safety. The purpose of the research was to: (1) demonstrate that psychosocial safety climate is a construct distinct from related climate measures (i.e., physical safety climate, team psychological safety, and perceived organizational support); and (2) test the proposition that organizational psychosocial safety climate determines work conditions (i.e., job demands) and subsequently worker psychological health. We used samples from two different cultures; an Australian sample (N = 126 workers in 16 teams within a primary health care organization) and a Malaysian sample (N = 180 workers in 31 teams from different organizations and diverse industries). In both samples confirmatory factor analysis verified that psychosocial safety climate is a construct distinct from related climate measures. Using hierarchical linear modeling, psychosocial safety climate was superior to other team level climate measures in its negative relationship to both job demands and psychological health problems. Results supported a mediation process, psychosocial safety climate → job demands → psychological health problems, corroborating psychosocial safety climate as a preeminent stress risk factor, and an efficient target for intervention. We found both physical and psychosocial safety climates were stronger in the Australian, compared with the Malaysian work context. Levels of psychosocial safety climate were significantly lower than those of physical safety climate in both countries indicating a ‘universal’ lack of attention to workplace psychological health.     

Resident Involvement in Natural Resource Management: open space conservation design in practice

The open space conservation sub-division offers an alternative to large-lot residential sub-divisions often seen as the culprit when urban sprawl transforms rural landscapes. Homes are sited on somewhat smaller lots, preserving natural areas for the local residents who share ownership of these communal areas and assume responsibility for their management. The article focuses on the experiences of residents of 13 relatively new open space communities. The interviews revealed that most of the communities have already confronted conflicting values with respect to natural areas, low resident participation and challenges in accessing appropriate information. While the open space conservation design holds great promise as a tool for innovative approaches to managing residential growth, it also calls for ways to anticipate and assist communities in caring for their local environment. Recommendations are offered for planning professionals based upon the experience of these open space community residents.     

Dealing with heterogeneous regression slopes in analysis of covariance: new methodology applied to environmental effects monitoring fish survey data

Analysis of covariance (ANCOVA) is a powerful statistical method which incorporates one or more covariates into the analysis to reduce error associated with measurement. ANCOVA (modeling response as a function of fish size) is frequently used to analyze environmental effects monitoring (EEM) fish survey data. In approximately 12% of fish survey data sets taken from cycles 1 to 3 of Environment Canada’s EEM database for pulp and paper mills, the standard assumption of parallel regression slopes is not met. For the first three cycles of the EEM program, these data sets were classified as indicating a mill effect, but for the most part were excluded from subsequent analyses aimed at quantifying the effect. We present two different methods for initially dealing with data sets that exhibit heterogeneous slopes so that they can be analyzed using the parallel slope model. The first method identifies data sets where heterogeneous slopes are forced by a few high-influence observations. The second approach identifies data sets where a model with heterogeneous slopes is statistically, but not practically, significant: with a high coefficient of determination for the parallel slope model. These new methodologies are applied to EEM pulp and paper data sets and about 55% of cases with heterogeneous slopes can be described by a parallel slope model. We also discuss a third method that can be used to describe mill effects when regression slopes remain heterogeneous even after applying the above two methods, enabling comparison with a critical effect size. These new methodologies could benefit the EEM program by enabling more data sets to be incorporated into meta-analyses and be used to make more equitable mill monitoring decisions in the future.     

The Triple Bottom Line for Sustainable Community Development

Rural communities in Australia are confronting a period of unprecedented change. They face declining commodity prices, the withdrawal of both public and private sector services, such as banks and hospitals, and the closure of small businesses. Their populations are in decline, with young people leaving for the larger regional centres. Many also face a declining resource base as soils become saline and water resources are sold to areas with higher unit returns. This paper presents a framework for sustainable community development based on emerging ideas of performance auditing and the development of progress indicators. The triple bottom line community audit approach is recast for the community level, measuring performance on improved community wellbeing, reduced environmental impact and increased economic vitality. Rural communities need to redefine their future. A sustainability focus offers a way forward. Las comunidades rurales en Australia estan afrontando un periodo de cambio sin precedente. Enfrentan disminución en los precios de los productos, retiro de servicios de ambos sectores, publico y privado, como bancos y hospitales y el cierre de pequeños negocios. Su población está disminuyendo, la gente joven emigra hacia centros regionales mas grandes. Muchos tambien enfrentan un deterioro en los recursos base ya que los suelos se tornan salinos, y los recursos de agua son vendidos a áreas con retorno de unidad mas alto. Este documento presenta una estructura para el desarrollo comunitario sostenible basado en el surgimiento de ideas de la revisión del desempeño y del desarrollo de indicadores de progreso. El enfoque de auditoria del triple resultado final esta rehecho para el nivel de la comunidad, midiendo el desempeño en el bienestar de la comunidad mejorada, el impacto ambiental reducido, y la vitalidad económica incrementada. Las comunidades rurales necesitan redefinir su futuro. Un enfoque sostenible ofrece una vía hacia adelante.     

Organization–environment adaptation: A macro‐level shift in modeling work distress and morale

We theorized that organization–environment adaptation, the interaction between external demands and personnel resources, predicts distress and morale. We tested this hypothesis in 29 stations within one state police department, and combined three data sources. We measured environmental demands for policing via census data pertaining to the station precinct (e.g., per cent unemployed; per cent in public housing). We assessed resources via personnel numbers within stations. Outcomes were employee's perceptions of staff distress and morale at the station (N = 247), assessed twice, 14 months apart. Using hierarchical linear modeling, we found that environmental demands predicted perceptions of workgroup distress and morale and that the relationships were moderated by personnel resources. For distress, when resources were low, demands were positively associated with distress; when resources were high, demands were negatively associated with distress. For morale, when resources were high, demands were positively associated with morale; there was no relationship when resources were low. Results show that aversive and pleasurable reactions at work may be traced to how resources are employed to manage external demands. Results support a macro‐level shift in modeling distress and morale, incorporating external demands, and strategic management decisions regarding personnel resourcing. Our research suggests that rather than being a result of individual failure to adapt, compromised work ability may result from an organizational failure to adapt to the environmental context.

Oviposition stimulants for the pipevine swallowtail butterfly,Battus philenor (Papilionidae), from anAristolochia host plant: Synergism between inositols,aristolochic acids and a monogalactosyl diglyceride

Aristolochia macrophylla (Lam.) is a major host of the pipevine swallowtail butterfly,Battus philenor (L.), in the eastern United States. The female butterflies use a synergistic mixture of inositols, acids and a lipid as oviposition cues in recognizing this plant on contact. The acids and lipid, all isolated from the Et₂O-CHCl₃ fraction of an alcoholic extract of fresh foliage, were identified as aristolochic acid I (1), aristolochic acid II (2) and 1,2-[di(9Z,12Z,15Z)-octadeca-9, 12, 15-trienoyl]-3-galactosyl-sn-glycerol (3). Identifications were facilitated by UV, MS (EI and FAB) and NMR (1D and 2D) spectral techniques and by analysis of the hydrolysis products of 3. The active inositols were identified as D-(+)-pinitol, reported previously, and sequoyitol. Though this is apparently the first report of oviposition responses to a diacyl glycerol glycoside by a phytophagous insect, responses to aristolochic acids and sequoyitol have been reported previously for anAristolochia-feeding swallowtail of a different genus in Japan. This indicates substantial evolutionary conservatism in chemical oviposition cues within the tribe Troidini.
