Rare Pride is a social marketing program that stimulates human behavior change in order to promote biodiversity conservation in critically threatened regions in developing countries. A series of formal evaluation studies, networking strategies, and evaluative inquiries have driven a 20-year process of adaptive management that has resulted in extensive programmatic changes within Pride. This paper describes the types of evaluation that Rare used to drive adaptive management and the changes it caused in Pride's theory-of-change and programmatic structure. We argue that (a) qualitative data gathered from partners and staff through structured interviews is most effective at identifying problems with current programs and procedures, (b) networking with other organizations is the most effective strategy for learning of new management strategies, and (c) quantitative data gathered through surveys is effective at measuring program impact and quality. Adaptive management has allowed Rare to increase its Pride program from implementing about two campaigns per year in 2001 to more than 40 per year in 2009 while improving program quality and maintaining program impact.  相似文献

ABSTRACT

Examining the territorial and logistical factors surrounding the leasing of the Greek port of Piraeus to a subsidiary of the Chinese state-owned enterprise COSCO, this paper responds to calls to investigate variations in experiences of precarity. The article is based on research conducted in 2014 when the container processing area at Piraeus was divided between two terminals: the first run by the Piraeus Port Authority (OLP) and the second run by COSCO’s subsidiary Piraeus Container Terminals (PCT). By contrasting the threatened unionized labour regime at OLP with the highly precarious labour conditions at PCT, the paper asks how the operative dimensions of capital condition precarity’s intensification and spread. In this light, precarity emerges not simply as a form of labour insecurity or an unevenly shared condition of human vulnerability but as a relational nexus that links questions of political economy to matters of subjectivity, space, power, and governance.  相似文献

Professional options traders priced risky prospects as well as uncertain prospects whose outcomes depended on future values of various stocks. The prices of the risky prospects coincided with their expected value, but the prices of the uncertain prospects violated expected utility theory. An event had greater impact on prices when it turned an impossibility into a possibility or a possibility into a certainty than when it merely made a possibility more or less likely, as predicted by prospect theory. This phenomenon is attributed to the subadditivity of judged probabilities.  相似文献

Narrative and its potential contribution to disability studies   总被引:2,自引:2,他引:0  
This article seeks to expand our understanding of narrative and the analysis of stories researchers invite and collect in the domain of disability studies. What narrative inquiry is and various reasons why researchers might opt to choose to turn to narratives are highlighted. Painting with broad strokes, narrative analysis is then considered before a typology of different ways in which stories can be analysed is offered. Illuminated by the typology are two contrasting standpoints on narrative analysis (storyteller and story analyst) and three specific methods (structural, performative, and autoethnographic creative analytic practices) that each standpoint might use to analyse the whats and hows of stories. The article closes by suggesting that researchers might consider using a variety of analyses in order to assist us to understand the complexities of the social world in diverse ways.  相似文献

The accessibility of dementia services to two groups of marginalised service users (people under 65 years of age and people from minority ethnic groups) was examined as part of a UK field study. In 61 interviews with a purposeful sample of professionals and paid carers in dementia care, the main issue in service access related to the small numbers of potential service users and their geographical dispersal. Other issues reflected those faced by people with dementia in general. At present, it seems as though decisions on care are based mainly on financial considerations and perceptions of the risk and dangerousness posed by people with dementia. These findings are linked to broader debates within the social model of disability about the need to address issues relating to people with learning impairments.  相似文献

There is widespread agreement in the natural sciences that observed increases in average global temperatures over the past century are due in large part to the anthropogenic (human generated) emission of greenhouse gases, primarily stemming from fossil fuel combustion and land use changes (e.g., deforestation). Many social processes have been identified for their contribution to climate change. However, few theoretical approaches have been used to study systematically the relations of the social with the biosphere. Our goal is to illustrate how the theory of metabolic rift provides a powerful approach for understanding human influence on the carbon cycle and global climate change. We extend the discussions of metabolism (the relationship of exchange between nature and humans) and metabolic rift to the biosphere in general and to the carbon cycle in particular. We situate our discussion of the metabolic rift in the historical context of an expanding, global capitalist system that largely influences the organization of human interactions with the environment. The general properties of a metabolic rift between nature and society include the disruption or interruption of natural processes and cycles, the accumulation of waste, and environmental degradation. Due to capitalism's inherent expansionary tendencies, technological development serves to escalate commodity production, which necessitates the burning of fossil fuels to power the machinery of production. As this process unfolded historically, it served to flood carbon sinks and generate an accumulation of carbon dioxide in the atmosphere. Technological “improvements” have actually increased the amount of resources used, since expansion in production typically outstrips gains in efficiency – a situation known as the Jevons paradox. The theory of the metabolic rift reveals how capital contributes to the systematic degradation of the biosphere.  相似文献

Robust methods for estimating rates of population change ( u ) are necessary for applied and theoretical goals in conservation and evolutionary biology. Traditionally, u has been calculated from either ratios of population counts (observed u or u obs ), or population models based on projection matrices (asymptotic u or u asy ,). New mark-recapture methods permit calculation of u from mark-resighting information alone (realized u or u rea ), but empirical comparisons with other methods are rare. In this paper, rates of population change were calculated for a population of green-rumped parrotlets ( Forpus passerinus ) that have been studied for more than a decade in central Venezuela. First, a ratio method based on counts of detected birds was used to calculate u obs. Next, a temporal symmetry method based on mark-recapture data (i.e. the u -parameterization introduced by Pradel, 1996) was used to calculate u rea . Finally, a stage-structured matrix model based on state-specific estimates of fecundity, immigration, local survival, and transition rates was used to calculate u asy . Analyses were conducted separately for females and males. Overall values of u from the three methods were consistent and all indicated that the finite rate of population change was not significantly different from 1. Annual values of u from the three methods were also in general agreement for a majority of years. However, u rea from the temporal symmetry method had the greatest precision, and apparently better accuracy than u asy . Unrealistic annual values of u asy could have been due to poor estimates of the transitional probability of becoming a breeder ( é ) or to a mismatch between the actual and the asymptotic stable stage distribution. In this study, the trade-off between biological realism and accuracy was better met by the temporal symmetry than the matrix method. Our results suggest that the temporal symmetry models can be applied with confidence to populations where less information may be available.  相似文献

There is a growing understanding that preventative child welfare efforts can be both more cost effective and are more desirable philosophically than strictly remedial programs. The Family Preservation Act provides funds to assist communities in strengthening and preserving at-risk families. In order to implement this program effectively, local communities must design new programs and procedures which will be both attractive to consumers and effective in meeting their needs. This study it identifies problems with contemporary child and family services and suggests solutions to those problems. This study uses a focus group format and presents ideas generated by those individuals who will be most directly affected by this legislation; front line service providers and service consumers. Several areas of weakness in the current service delivery system are identified, including bureaucratic barriers, limited resources, problematic consumer/provider relations and a range of collaborative issues, both within and between agencies and the communities they serve.  相似文献
