Abstract We argue that attempts to superimpose park regulatory regimes on existing land uses in the tropics represent conflicts between alternative cultural models of natural resource management. The results of such conflicts are unique regulatory regimes emerging from distinctive processes that redefine the terms and limits of natural resource use. In creating a scarcity of available resources, parks encourage social differentiation and greater awareness of societal patterns of inequality, establishing a potential for the articulation of demands for social and environmental equity. We evaluate these claims with a case study of the Cerro Azul Meambar National Park in Honduras. We base our analysis on 54 indepth interviews of Park residents in five Park communities.  相似文献

If we accept that social research is not simply a matter of representation, but involves actively intervening in and constructing our current social and political conditions, we are then presented with a set of problems about representation and intervention. The methodology, memory‐work, is introduced here as one specifically developed for the purposes of undertaking politically engaged social research. In this paper, I describe the rationale and method of memory‐work, emphasizing the ways in which it involves undoing the subject of linear, causal, biographical narratives and a notion of the subject as collectively constituted. I elucidate the method by drawing on an example from research about HIV subjectification in which the notion of individual responsibility arose as a problem for memory‐workers—it simultaneously enables and constrains actively working on oneself and one's world. Discussing this research leads to a consideration of the ways in which the methodology needs to be adapted to reflect the specific concerns of one's time and place. I conclude with a discussion of the important but limited notion of history entailed in the original conception of memory‐work.  相似文献

When appropriately used, simulations are powerful educational tools for the social work educator. A simulation permits the student to experience an approximation of reality, thereby generating interest and a more relevant classroom environment When it is not feasible to use extant simulation games, educators need to design their own—ones adapted to particular time limitation and course objectives. Two examples of “homemade” simulations are presented. One focuses on community power, the other on grant writing.  相似文献

While two-stage designs in problem gambling research are expensive and relatively difficult to execute, they have the potential to yield more accurate prevalence estimates as well as valuable additional information about gambling and problem gambling in the community. However, gains in precision are heavily dependent on the accuracy of the screening methods used and the sample sizes involved. Sound practice requires reliable information about the variances and confidence levels associated with different screens. In the spirit of contributing to the ongoing dialog about ways to improve the measurement of problem gambling, we examine several reasons to question whether the revised estimates offered by Gambino are in fact an improvement.  相似文献

A population of 72 bifocal wearers was studied to determine the relationship between VDT (video display terminal) placement for those who reported musculoskeletal pain and those who did not. The mean hours worked was 50.4 minutes (p=0.003) greater for those who reported head/neck pain versus those who did not and 48.6 minutes (p=0.004) greater for those who reported shoulder/arm pain that those who did not. There was no statistically significant difference between the means of monitor height, distance, or angle for those who reported pain symptoms versus those who did not. This study indicates that, self reported pain symptoms are correlated with hours of VDT work and that there appears to be a threshold at approximately five hours for pain symptoms among bifocal wearers. No such correlation can be made for monitor placement  相似文献
