The relationship of organizational politics and support to work behaviors,attitudes, and stress

The purpose of this paper is to report two studies that investigated the consequences of organizational politics and organizational support on two separate samples of employees. Study 1 surveys 69 full-time employees, while Study 2's sample includes 185 part-time workers. Four major findings were observed. First, the present studies replicated prior findings concerning the relationships of politics and support to such variables as withdrawal behaviors, turnover intentions, job satisfaction and organizational commitment. In general, politics is related to negative work outcomes while support is related to positive ones. Consistent results were obtained within both the full- and part-time samples. Second, we elaborated upon previous work concerning the relationship of politics and support to job involvement. Third, we found in both samples that politics and support did predict above and beyond each other, suggesting that they should be viewed as separate constructs rather than opposite ends of a single continuum. Lastly, Study 2 extended the research on politics and support by analyzing their relationships to four work stress variables: job tension, somatic tension, general fatigue, and burnout. Each of these four variables was predicted by both politics and support. © 1997 by John Wiley & Sons, Ltd.     

Using a Systematic Approach to Select Flagship Species for Bird Conservation

Conservation marketing campaigns that focus on flagship species play a vital role in biological diversity conservation because they raise funds and change people's behavior. However, most flagship species are selected without considering the target audience of the campaign, which can hamper the campaign's effectiveness. To address this problem, we used a systematic and stakeholder‐driven approach to select flagship species for a conservation campaign in the Serra do Urubu in northeastern Brazil. We based our techniques on environmental economic and marketing methods. We used choice experiments to examine the species attributes that drive preference and latent‐class models to segment respondents into groups by preferences and socioeconomic characteristics. We used respondent preferences and information on bird species inhabiting the Serra do Urubu to calculate a flagship species suitability score. We also asked respondents to indicate their favorite species from a set list to enable comparison between methods. The species’ traits that drove audience preference were geographic distribution, population size, visibility, attractiveness, and survival in captivity. However, the importance of these factors differed among groups and groups differed in their views on whether species with small populations and the ability to survive in captivity should be prioritized. The popularity rankings of species differed between approaches, a result that was probably related to the different ways in which the 2 methods measured preference. Our new approach is a transparent and evidence‐based method that can be used to refine the way stakeholders are engaged in the design of conservation marketing campaigns.     

Risk Factors for Death in the 27 March 1994 Georgia and Alabama Tornadoes

Field surveys were made one week after tornadoes killed 40 persons and injured over 300 in rural regions of Alabama and Georgia, USA, on 27 March 1994. Surveys were completed for samples of 20 persons who were killed and 31 persons who were in the paths of the tornadoes but survived to determine whether there were differences in personal characteristics, behavior or location between the two groups. Persons who died were significantly older than persons who survived, more likely to be in mobile homes or in rooms above ground with windows, less likely to be watching television before the tornado, and were aware of the approaching tornado for less time than survivors. There was no difference in gender, race, marital status, education, disability or previous experience with tornadoes between those who died and survivors.     

Oil: 'Market Forces'

The traditional concept of price dependence on supply and demand does not apply fully to the oil industry where price and supply is often the result of agreements between the major oil companies and the major suppliers. As a result, prices respond very slowly to changes in demand and supply. Government intervention for political reasons or for reasons of national security acts to further lessen the effect of market forces. In the absence of true market forces some government intervention may be justified.
Le concept traditionnel qui stipule que les prix sont fonction de l'offre et de la demande ne s'applique pas dans son entier à l'industrie pétrolière où les prix et l'approvisionnement sont souvent le résultat d'accords entre les grandes compagnies pétroliéres et les principaux fournisseurs. En conséquence, les prix s'adaptent très lentement aux changements enregistrés dans l'offre et la demande. L'intervention du gouvernement pour des raisons politiques ou de sécurité nationale a pour effet de diminuer encore davantage la portée des forces du marché. En l'absence de forces de marché effectives, une intervention gouvernementale limitée peut se justifier.
El concepto tradicional de la fijación de precios por el juego de la oferta y la demanda no es completamente aplicable a la indùstria del petróleo donde el precio es mas bien consecuencia de los acuerdos entre los grandes productores y consumidores de petróleo. Como resultado, los precios responden muy lentamente a los cambios en la oferta y demanda. La intervención del gobierno por razones poliíticas o de seguridad nacional debilita aun más las fuerzas del mercado. En ausencia de estas fuerzas, alguna forma de intervención gubernamental es justificable.     

Biological Effects of Fine Sediment in the Lotic Environment

/ Although sedimentation is a naturally occurring phenomenon inrivers, land-use changes have resulted in an increase in anthropogenicallyinduced fine sediment deposition. Poorly managed agricultural practices,mineral extraction, and construction can result in an increase in suspendedsolids and sedimentation in rivers and streams, leading to a decline inhabitat quality. The nature and origins of fine sediments in the loticenvironment are reviewed in relation to channel and nonchannel sources andthe impact of human activity. Fine sediment transport and deposition areoutlined in relation to variations in streamflow and particle sizecharacteristics. A holistic approach to the problems associated with finesediment is outlined to aid in the identification of sediment sources,transport, and deposition processes in the river catchment. The multiplecauses and deleterious impacts associated with fine sediments on riverinehabitats, primary producers, macroinvertebrates, and fisheries are identifiedand reviewed to provide river managers with a guide to source material. Therestoration of rivers with fine sediment problems are discussed in relationto a holistic management framework to aid in the planning and undertaking ofmitigation measures within both the river channel and surrounding catchmentarea.KEY WORDS: Sedimentation; Fine sediment; Holistic approach; Ecologicalimpact; River restoration     

A Landscape Approach to Biodiversity Conservation of Sacred Groves in the Western Ghats of India

Abstract:  Although sacred groves are important for conservation in India, the landscape that surrounds them has a vital influence on biodiversity within them. Research has focused on tree diversity inside these forest patches. In a coffee-growing region of the Western Ghats, however, landscape outside sacred groves is also tree covered because planters have retained native trees to provide shade for coffee plants. We examined the diversity of trees, birds, and macrofungi at 58 sites—10 forest-reserve sites, 25 sacred groves, and 23 coffee plantations— in Kodagu district. We measured landscape composition and configuration around each site with a geographic information system. To identify factors associated with diversity we constructed multivariate models by using a decision-tree technique. The conventional measures of landscape fragmentation such as patch size did not influence species richness. Distance of sacred groves from the forest reserve had a weak influence. The measures of landscape structure (e.g., tree cover in the surroundings) and stand structure (e.g., variability in canopy height) contributed to the variation in species richness explained by multivariate models. We suggest that biodiversity present within sacred groves has been influenced by native tree cover in the surrounding landscape. To conserve this biodiversity the integrity of the tree-covered landscape matrix will need to be conserved.     

Social Capital in Biodiversity Conservation and Management

Abstract:  The knowledge and values of local communities are now being acknowledged as valuable for biodiversity conservation. Relationships of trust, reciprocity and exchange, common rules, norms and sanctions, and connectedness in groups are what make up social capital, which is a necessary resource for shaping individual action to achieve positive biodiversity outcomes. Agricultural and rural conservation programs address biodiversity at three levels: agrobiodiversity on farms, nearby nature in landscapes, and protected areas. Recent initiatives that have sought to build social capital have shown that rural people can improve their understanding of biodiversity and agroecological relationships at the same time as they develop new social rules, norms, and institutions. This process of social learning helps new ideas to spread and can lead to positive biodiversity outcomes over large areas. New ideas spread more rapidly where there is high social capital. There remain many practical and policy difficulties, however, not least regarding the need to invest in social capital formation and the many unresolved questions of how the state views communities empowered to make their own decisions. Nonetheless, attention to the value of social relations, in the form of trust, reciprocal arrangements, locally developed rules, norms and sanctions, and emergent institutions, has clearly been shown to deliver a biodiversity dividend in many contexts. This suggests a need to blend both the biological and social elements of conservation.     

Mapping Hotspots of Threatened Species Traded in Bushmeat Markets in the Cross–Sanaga Rivers Region

Bushmeat markets exist in many countries in West and Central Africa, and data on species sold can be used to detect patterns of wildlife trade in a region. We surveyed 89 markets within the Cross–Sanaga rivers region, West Africa. In each market, we counted the number of carcasses of each taxon sold. During a 6‐month period (7594 market days), 44 mammal species were traded. Thirteen species were on the International Union for Conservation of Nature (IUCN) Red List or protected under national legislation, and at least 1 threatened species was traded in 88 of the 89 markets. We used these data to identify market groups that traded similar species assemblages. Using cluster analyses, we detected 8 market groups that were also geographically distinct. Market groups differed in the diversity of species, evenness of species, and dominant, prevalent, and characteristic species traded. We mapped the distribution of number of threatened species traded across the study region. Most threatened species were sold in markets nearest 2 national parks, Korup National Park in Cameroon and Cross River in Nigeria. To assess whether the threatened‐species trade hotspots coincided with the known ranges of these species, we mapped the overlap of all threatened species traded. Markets selling more threatened species overlapped with those regions that had higher numbers of these. Our study can provide wildlife managers in the region with better tools to discern zones within which to focus policing efforts and reduce threats to species that are threatened by the bushmeat trade.

Planning for Long, Wide Conservation Corridors on Private Lands in the Oak Ridges Moraine, Ontario, Canada

Abstract:  We explored the role of conservation biology in the planning of a natural-heritage system that includes long, wide conservation corridors situated primarily on private lands, and established to connect natural core areas in the Oak Ridges Moraine of Ontario, Canada. We based our review on government documents, semi-structured interviews with participants involved in this land-use planning process, and our involvement with the issue from 1990 through 2002. Conservation biology had a major influence on the outcome of the land-use planning process for this moraine. The landform was identified as an area of value by the environmental movement within the context of a number of ongoing government studies that began in the late 1980s and early 1990s. Conservation biologists and planners in government, the environmental movement, and the private sector carried out work related to conservation biology, including inventories and the development and application of criteria for the delineation of core areas and conservation corridors. Once the political timing was favorable (2001–2002), decision makers linked the science of conservation biology to planning policies and law in Ontario. The Oak Ridges Moraine land-use planning process was precedent setting in Canada, and possibly internationally. To our knowledge this is the first time long, wide conservation corridors on private lands were regulated through land-use-planning legislation and led to restrictions on urban development and aggregate resource extraction.
