Analyses of data from 600 households in the province of Lubin, Poland, five years after the economic transformation indicated the transfers of goods and services between households to be quite prevalent, with households with high levels of resources giving goods and services and those with low levels of resources receiving goods and services. The receipt of such transfers does not improve the living conditions of the receiving households relative to those who do not receive help; in fact, those receiving help report lower levels of satisfaction than those not receiving assistance. 相似文献

This study examines the role of individual- and family-level factors in predicting the length of shelter stays for homeless families. Interviews were conducted with all families exiting one of six emergency family shelters in Worcester, Massachusetts, between November 2006, and November 2007. Analyses, using an ordinary least squares regression model, find that families with a positive alcohol or drug screen in the year prior stay 85 days longer than those without a positive screen; families leaving shelter with a housing subsidy stay 66 days longer than those leaving without a subsidy. Demographic factors, education, employment, health, and mental health are not found to predict shelter stay duration. Consistent with prior research, housing resources relate to families' time in shelter; with the exception of a positive substance abuse screen, individual-level problems are not related to their time in shelter. Efforts to expand these resources at the local, state, and national levels are a high priority. 相似文献

The study explored whether perceived shared experience with a media portrayal could influence various cognitions—such as concern, sense of personal involvement, and desire to learn more—that are important for behavior change. This research used the situational theory of publics in order to evaluate whether perceived shared risk is an antecedent to the factors leading to communication behavior. In general, the findings from this experiment supported the idea that shared risk experience with portrayals in news coverage has the potential to influence problem recognition, involvement recognition, and a new variable that combines information seeking and processing: that of information gaining. 相似文献

In this paper D- and V-optimal population designs for the quadratic regression model with a random intercept term and with values of the explanatory variable taken from a set of equally spaced, non-repeated time points are considered. D-optimal population designs based on single-point individual designs were readily found but the derivation of explicit expressions for designs based on two-point individual designs was not straightforward and was complicated by the fact that the designs now depend on ratio of the variance components. Further algebraic results pertaining to d-point D-optimal population designs where d≥3 and to V-optimal population designs proved elusive. The requisite designs can be calculated by careful programming and this is illustrated by means of a simple example. 相似文献

This article provides evidence of the prevalence of wills and the principles underpinning the intended distribution of estates in Australia. Intentions around wealth transfers and the social norms that underpin them occur in the context of predicted extensive intergenerational transfers from the ageing baby boomer generation, policies of self provision and user pays for care in old age, broader views on what constitutes ‘family’, the increased importance of the not‐for‐profit sector in the delivery of services, and the related need for philanthropy. A national telephone survey conducted in 2012 with 2,405 respondents aged 18 and over shows that wills are predominantly used to distribute assets to partners and/or equally to immediate descendants. There is little evidence that will makers are recognising a wider group of relationships, obligations and entitlements outside the traditional nuclear family, or that wills are being replaced by other mechanisms of wealth transfer. Only a minority consider bequests to charities as important. These findings reflect current social norms about entitlements to ‘family’ money, a narrow view of what and who constitutes ‘family‘, limited obligation for testators to recompense individuals or organisations for care and support provided, and limited commitment to charitable organisations and civil society. 相似文献

Primary objective: To determine the relative uses of neural action potential (‘spike’) data versus local field potentials (LFPs) for modeling
information flow through complex brain networks. Hypothesis: The common use of LFP data, which are continuous and therefore more mathematically suited for spectral information-flow
modeling techniques such as Granger causality analysis, can lead to spurious inferences about whether a given brain area ‘drives’
the spiking in a downstream area. Experiment: We recorded spikes and LFPs from the forelimb motor cortex (M1) and the magnocellular red nucleus (mRN), which receives
axon collaterals from M1 projection cells onto its distal dendrites, but not onto its perisomatic regions, as rats performed
a skilled reaching task. Results and implications: As predicted, Granger causality analysis on the LFPs—which are mainly composed of vector-summed dendritic currents—produced
results that if conventionally interpreted would suggest that the M1 cells drove spike firing in the mRN, whereas analyses
of spiking in the two recorded regions revealed no significant correlations. These results suggest that mathematical models
of information flow should treat the sampled dendritic activity as more likely to reflect intrinsic dendritic and input-related
processing in neural networks, whereas spikes are more likely to provide information about the output of neural network processing. 相似文献
