Five focus groups substantially agreed about the lack of paternal participation in child welfare services and the reasons for low paternal involvement. The groups had considerable disagreement about whether child welfare professionals should address this issue. Some caseworkers believed that all fathers and mothers should be treated identically with respect to services to be offered and time frames for services; other caseworkers thought that the special circumstances of some fathers, such as lack of child care experience, called for service approaches that differ from those for mothers. Another disagreement was whether more fathers would be more involved if services were gender sensitive, that is, if agencies provided male caseworkers for fathers and had father-only services. Much of the debate focused on pragmatic considerations (would gender-sensitive services improve paternal participation and outcomes?), although some participants were concerned about equity (would such services give fathers an advantage in disputed custody cases?).  相似文献

Two aspects of the structure of existing social security systems limit the scope for containing costs by increasing targeting: the insurance principle, and the use of category membership to establish eligibility for benefits. The first aspect is antithetical to targeting because the most needy people are also the most likely to fail to establish an adequate contributions record. Some countries appear committed to maintaining the insurance principle because it is part of the fabric of the relationship between employers, employees and the State. The second aspect can be seen as an effective way of identifying groups whose income is likely to fall short of their needs. However, the primary function of category definition is to establish the legitimacy of claims—to examine why a shortfall of income in relation to needs has arisen, what personal responsibility the claimant bears, and what alternative mechanisms might be available. Several countries have revised category definitions in response to issues about the motivation and "deservingness" of claimants. We designate as "pseudo-targeting" reforms of this type, which are not likely to result in the allocation of a higher share of social expenditure to the worst-off. The scope for increasing targeting in existing systems is very restricted, reflecting the limitations of the concept. Non-categorical social assistance is the archetypal targeted benefit, and it has serious limitations. The obstacles to targeting are integral to the legitimation of social security. If targeting reforms undermine this legitimating structure, they risk undermining the claim on resources exercised by the social security system.  相似文献

New Public Management Is Dead--Long Live Digital-Era Governance   总被引:1,自引:0,他引:1  
The "new public management" (NPM) wave in public sector organizationalchange was founded on themes of disaggregation, competition,and incentivization. Although its effects are still workingthrough in countries new to NPM, this wave has now largely stalledor been reversed in some key "leading-edge" countries. Thisebbing chiefly reflects the cumulation of adverse indirect effectson citizens' capacities for solving social problems becauseNPM has radically increased institutional and policy complexity.The character of the post-NPM regime is currently being formed.We set out the case that a range of connected and informationtechnology–centered changes will be critical for the currentand next wave of change, and we focus on themes of reintegration,needs-based holism, and digitization changes. The overall movementincorporating these new shifts is toward "digital-era governance"(DEG), which involves reintegrating functions into the governmentalsphere, adopting holistic and needs-oriented structures, andprogressing digitalization of administrative processes. DEGoffers a perhaps unique opportunity to create self-sustainingchange, in a broad range of closely connected technological,organizational, cultural, and social effects. But there arealternative scenarios as to how far DEG will be recognized asa coherent phenomenon and implemented successfully.  相似文献

Falls can impair health and reduce quality of life among older adults. Although many factors are related to falling, few analyses examine causal models of this behavior. In this study, factors associated with falling were explored simultaneously using structural-equation modeling. A variety of cognitive, physical-performance, and health measures were administered to 694 older adult drivers from the state of Maryland. The observed and latent variables of age, cognitive ability, physical functioning, health, and falling behavior were used to create a causal model. The model revealed that being older was associated with declines in cognition, and such cognitive declines predicted increased falling. Similarly, poorer health was related to poorer physical functioning, which, in turn, also predicted increased falling. This model indicates that in addition to existing fall-prevention interventions aimed at improving physical functioning, interventions to improve cognition and health might also be effective. It is speculated that fear of falling, which often results in reduced mobility among older adults, might account for the lack of a direct relationship between age and falling. This hypothesis should be examined in further research.  相似文献

This article illustrates the use of high-resolution color graphic images obtained from raster terminals to reduce an immense amount of data into a few meaningful time series. The steps that were taken to achieve this data reduction and their appropriate images are given. The time series were analyzed using Box and Jenkins time series methods (see also McCleary and Hay 1980), and the results are discussed.  相似文献
