The demand for biodiversity data is increasing. Governments require standardised, objective data to underpin planning and conservation decisions. These data are produced by large numbers of (volunteer) natural historians and non-governmental organisations. This article analyses the interface between the state and the volunteer naturalists to understand the emerging patterns of information flow between them. Our results are based on research in the UK and the Netherlands. These two countries have a long history in volunteer biodiversity recording and are facing similar issues in relation to the increasing demand for standardised data. Our findings demonstrate that citizens who become involved in recording do so because they value nature and biodiversity. Recording is for them a way to enact their relationship with nature and contribute to its protection. Our findings also show that they are concerned about the increasing rationalisation in the process of data flow and about the way in which the government treats them and ‘their’ data. Our paper concludes by discussing this tension and the challenges and opportunities for biodiversity recording.  相似文献

The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at Weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < .05) improvements relative to those in CG (Barthel Index at Weeks 0 and 36: 73.41 (± 2.35) and 77.0 (± 2.38) for the FCT and 70.79 (± 2.53) and 66.73 (± 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults.  相似文献

This short‐term longitudinal study examined whether the social resources of important nonparental adults (VIPs) perceived by youth during their senior year of high school had a significant relation to their educational and socioemotional adjustment 1 year later. One month before their high school graduation, a multiethnic sample of youths (N=754) reported on their grades, educational expectations, and selected psychosocial characteristics (i.e., depressed mood and misconduct); the educational attainment and perceived psychosocial characteristics of an important nonparental adult in their lives; and the educational plans and perceived psychosocial characteristics of their close friends. Key measures were included in a mailed survey 1 year later. VIP characteristics (particularly their educational attainment) were associated with post‐high school adjustment, even after controlling for previous level of youth adjustment and contributions from demographic and peer characteristics.  相似文献

In this article, we show how to use administrative data from the Matrícula Consular de Alta Seguridad (MCAS) identification card program to measure the joint distribution of sending and receiving locations for migrants from Mexico to the United States. Whereas other data sources cover only a small fraction of source or destination locations or include only very coarse geographic information, the MCAS data provide complete geographic coverage of both countries, detailed information on migrants’ sources and destinations, and a very large sample size. We first confirm the quality and representativeness of the MCAS data by comparing them with well-known household surveys in Mexico and the United States, finding strong agreement on the migrant location distributions available across data sets. We then document substantial differences in the mix of destinations for migrants from different places within the same source state, demonstrating the importance of detailed substate geographical information. We conclude with an example of how these detailed data can be used to study the effects of destination-specific conditions on migration patterns. We find that an Arizona law reducing employment opportunities for unauthorized migrants decreased emigration from and increased return migration to Mexican source regions with strong initial ties to Arizona.  相似文献

As new and more effective human reproductive genetic technologies (RGTs) rapidly develop, religious voices remain an important part of public discussion about the moral standing of such technologies. Here, we compare how individuals from different religious traditions evaluate disease RGTs (detecting genetic diseases in vitro) when compared to enhancement RGTs, allowing parents to select features of a child. Findings are gleaned from analysis of 270 interviews with individuals from 23 Christian, Muslim, and Jewish religious organizations, with supporting data from a national survey of more than 10,000 Americans. We find that respondents engage in clearly defined discursive moral reasoning to evaluate the propriety of disease RGTs while moral intuitions manifest themselves in responses to enhancement RGTs. We argue that schemas provide resources for moral discourses while also shaping moral intuitions expressed through emotions. Our results have implications for how religious people respond to new technologies when their institutional and denominational structures do not have readily discernable moral frameworks to guide responses.  相似文献

This study's main objective was to explore whether beliefs legitimizing dating violence predict dysfunctional social information processing (SIP) when adolescents deal with ambiguous dating situations, and whether this more proximal cognitive processing acts as a mediator between acceptance of violence beliefs and dating violence perpetration. Participants were 855 high school students who completed self‐report measures at three time points, with a 1‐year interval between them. SIP did not act as a mediator, but the emergence of anger emotions in dating conflict situations, along with aggression‐justifying beliefs, were revealed as essential in explaining dating violence. Previous aggression also explained a subsequent higher anticipation of positive consequences for aggressive acts. We discuss the implications for prevention and treatment strategies with adolescents.  相似文献

Significant non-parental adults likely play an important role in the lives of children and adolescents. This study explores the frequency and quality of contact youth have with non-parental adults and the relationship of this contact with child behavior. An instrument designed to measure contact with non-parental adults in a sensitive and inclusive manner is also presented. Seventy-five mothers were surveyed regarding their childs contact with non-parental adults and their childs behavior. Results indicate that children with more frequent and high quality contact with non-parental adults have fewer behavior problems. Relationships with specific categories of adults are examined and implications for social work practice are discussed.  相似文献

The optimism regarding opportunities for women to enter the professionalization process in software development during the past years has not been fully realized and the gender gap in Germany's information technology (IT) sector still persists. Women are almost completely unrepresented in the technical fields of the German software industry, particularly in small enterprises. In this article, I firstly offer an overview of the German IT sector's development and current status. Secondly, I discuss the construction of expertise and gendered meanings in the practice of software development and related implications for the enrolment of women in this field. Gender stereotypical assumptions about expertise in the practice of software development and structural factors related to the lack of life–work balance programmes, as well as the lack of internal training in most IT companies, contribute to organizational segregation  相似文献

In this study, nine roles and responsibilities of boards of directors in nonprofit organizations in Israel are examined and perceptions of these roles and responsibilities by chairpersons of the boards and the executive directors are compared. Four groupings of board roles were found: senior human resource management, maintenance of relationships with the task environment, policymaking, and fiscal management and fundraising. The findings show that in most organizations boards fulfill all these roles and play a significant role in decision making. A significant consensus exists between chairpersons and executive directors in respect to most of the boards' roles, whereas significant differences in perceptions were found in respect to financial matters and maintenance of relationships with the task environment.  相似文献
