Abstract

The article by McDonald and Jones raises some very important issues for Australian social work, and identifies some of the key decisions that social workers in Australia will be required to make if their practice is to maintain some degree of relevance in the changing context of the early twenty-first century.  相似文献

The paper attempts to describe the similarities and differences between organizational development (OD) and human resource development (HRD). While it is argued that HRD practitioners need to acquire some of the skills of OD consultants, these are likely to be limited to the development of personal skills and learning in the attempt to achieve intrapreneurialism and personal transformations. We argue that HRD is living in the shadow of OD because it is slow to recognize its roots in the debates of that discipline. It is therefore suggested that HRD will recognize its true potential only when it identifies its core knowledge and skills. We argue that HRD can find its essential identity in four main ways: by focusing on the organization's business strategy; by devolving responsibility to line managers; by adopting an employee-centred approach to learning; and by emphasizing workplace learning. However, a wider behavioural understanding and a greater degree of reflectiveness in relation to the politics of change and the skills of the change agent must inform this identity.  相似文献

There is much social gerontological research suggesting that the aged in our society constitute a minority group or separate stratum. This separateness, in combination with a lack of a clear conception of the elderly role, has led to a preponderance of stereotyped images of the elderly. A mailed questionnaire was returned by 224 retirees of a large utility company in the Southwest and provided a data base to test a conceptual model of the dynamics of the process of acceptance or denial of age‐appropriate behavioral expectations. The model, grounded in the reference group theoretical approach, was concerned expressly with the operationalization of factors thought to influence whether the elderly accept age‐appropriate behavioral expectations as pertinent to their life situation. Whether the people in this particular population accept others' expectations for their behavior was found to be affected by their perception of the expectations of family members and friends and whether the respondents characterized themselves as subject to age‐related shortcomings. In addition, friends were found to be a more salient reference group in conveying age‐appropriate behavioral expectations than family members. The analysis provided general support for the reference group approach and suggested a broader application of the concept in the gerontological literature.  相似文献

One of the most established approaches to explain attitudes toward immigration is group conflict theory. However, even though the theory was articulated in dynamic terms, previous research has almost exclusively tested it through cross‐sectional analyses. The aim of this study is to disentangle the dynamic character of ethnic competition from more permanent determinants of ethnic threat. The findings show that a remarkable variation of concern over immigration, usually attributed to permanent positions of economic vulnerability, disappears when within‐person variation is modeled. In line with a dynamic approach of ethnic competition, becoming unemployed or being laid off increases concern over immigration. This effect is independent of social class.  相似文献

Urban greening contributes notably to quality of life and ecosystem services in cities. Compact cities in developing and developed countries are commonly beset by greenspace deficit. Based on literature review supplemented by field studies in different cities, a sustainable urban greening strategy is proposed. Urban renewal and new developments without a greening vision could miss the opportunities to bring relief. The public and private sectors can join hands to insert plantable spaces into the urban fabric. Urban greenspaces (UGS) with good connectivity forming a green network to permeate the city constitute the hallmarks of a naturalistic design. Preservation and creation of natural areas with rich biodiversity offer a new dimension to UGS design. Greening benefits could be expressed in economic terms to complement conventional ecological-environmental emphasis. Outstanding trees could receive high-order conservation efforts, and trees in construction sites warrant enhanced protection. Tree transplanting demands an overhaul in concepts and skills. Improving roadside tree planting and maintenance offers a cost-effective way to upgrade the townscape. Ameliorating widespread soil limitations could remove a major hindrance to tree growth. Innovative ideas of development right transfer, street pedestrianization, river and canal revitalization, green roofs and green walls could mobilize hitherto underused plantable resources. Lacking appropriate institutional setup and scientific capability pose intractable bottlenecks. Innovative public policies and greening technologies are needed for sustained improvements. Amalgamating natural and social sciences in a multidisciplinary approach and reinforcing the link between science and public policies could overhaul greening.  相似文献

This study examines how exploiting biases in probability judgment can enhance deterrence using a fixed allocation of defensive resources. We investigate attacker anchoring heuristics for conjunctive events with missing information to distort attacker estimates of success for targets with equal defensive resources. We designed and conducted a behavioral experiment functioning as an analog cyber attack with multiple targets requiring three stages of attack to successfully acquire a target. Each stage is associated with a probability of successfully attacking a layer of defense, reflecting the allocation of resources for each layer. There are four types of targets that have nearly equal likelihood of being successfully attacked, including one type with equally distributed success probabilities over every layer and three types with success probabilities that are concentrated to be lowest in the first, second, or third layer. Players are incentivized by a payoff system that offers a reward for successfully attacked targets and a penalty for failed attacks. We collected data from a total of 1,600 separate target selections from 80 players and discovered that the target type with the lowest probability of success on the first layer was least preferred among attackers, providing the greatest deterrent. Targets with equally distributed success probabilities across layers were the next least preferred among attackers, indicating greater deterrence for uniform-layered defenses compared to defenses that are concentrated at the inner (second or third) levels. This finding is consistent with both attacker anchoring and ambiguity biases and an interpretation of failed attacks as near misses.  相似文献

High rates of mortality on long term carcinogenicity studies can often result in challenges when it comes to the statistical analysis of tumor incidence. The current regulatory advice often results in treated groups being terminated earlier than the control group. However, this advice rarely considers the impact of this action on the statistical analyses. The nature of these analyses means that groups terminated at different times may not be directly comparable due to age differences of the animals. Here we discuss the issues related to this and investigate several approaches of how to incorporate these groups within the statistical analyses. Although no single method appears to resolve these issues consistently, inclusion of the early terminated group is still informative. Depending on the timing of the early termination, either pooling of the groups into a single terminal kill (TK) interval or reassignment of intervals based purely on time of death (ie, no separate TK interval) appear preferable. However, to draw meaningful conclusions the time of onset of a given tumor must also be considered alongside incident rates and any statistical findings.  相似文献

The spread of COVID‐19 acutely challenges and affects not just economic markets, demographic statistics and healthcare systems, but indeed also the politics of organizing and becoming in a new everyday life of academia emerging in our homes. Through a collage of stories, snapshots, vignettes, photos and other reflections of everyday life, this collective contribution is catching a glimpse of corona‐life and its micro‐politics of multiple, often contradicting claims on practices as many of us live, work and care at home. It embodies concerns, dreams, anger, hope, numbness, passion and much more emerging amongst academics from across the world in response to the crisis. As such, this piece manifests a shared need to — together, apart — enact and explore constitutive relations of resistance, care and solidarity in these dis/organizing times of contested spaces, identities and agencies as we are living–working–caring at home during lockdowns.  相似文献
