The solution to the errors-in-variables problem computed through total least squares is highly nonlinear. Because of this, many statistical procedures for constructing confidence intervals and testing hypotheses cannot be applied. One possible solution to this dilemma is bootstrapping. A nonparametric bootstrap technique could fail. Here, the proper nonparametric bootstrap procedure is provided and its correctness is proved. On the other hand, a residual bootstrap is not valid and suitable in this case. The results are illustrated through a simulation study. An application of this approach to calibration data is presented.  相似文献

This study adopted the theoretical framework of Schaefer and Moos (1992) to identify the resources that contributed to the personal growth and quality of life of 56 grandparents of childhood cancer survivors and compare them with 60 grandparents of healthy children. Participants filled out questionnaires addressing sense of coherence, social support, personal growth, and quality of life. A significant difference was found only with regards to personal growth. Hierarchical regressions revealed that health, economic status, higher levels of sense of coherence, and support contributed to quality of life, whereas being a grandparent of a child who survived cancer, lower sense of coherence, support, and past experience of the Holocaust contributed to personal growth. It seems that though they are both positive dimensions, quality of life and personal growth represent different entities in grandparents’ lives. This study sheds light on the experiences and perspectives of grandparents, indicating that alongside the physical and emotional toll taken by their grandchild’s illness, there are also positive implications that can lead to personal growth. Strengthening grandparents could enable families to take advantage of the potential contribution of one of the most committed support providers in the family.  相似文献

This paper studies two processes of civil service reform in Slovakia during the period of 2014–2015 in order to reflect on the involvement of an ‘outsider-academic’ and her strategies to achieve policy impact. The context of such involvement are multi-level processes permeated by political interests and poor on evidence, which favour strategic interests, bargaining and political pressure and contestation (the mode of ‘powering’) and a mode of legal-based ‘puzzling’ as opposed to a conceptual, intellectual search for solutions friendly towards outside academics—and achieving only incremental results. We theorise on the success of these strategies (including helping serendipity, throwing ideas to see what sticks, mobilising allies, anchoring a non-binding concept, and finding and developing long-term connections) and sketch analogies and differences between the position of an outsider-academic and a policy entrepreneur. We rely on auto-ethnographic data and documentation of the work of the committees involved and their outputs.  相似文献

It is well established that acquiring financial skills during childhood is linked with better savings in adulthood. Little is known, however, about the relationship between parental teaching of money management early in life and children's financial outcomes in adulthood. This is particularly true for low- and moderate-income (LMI) households. Using data from Community Advantage Program survey data for 2,389 LMI homeowners, we find that adults who report receiving high levels of money-management teaching in childhood from their parents are associated with higher credit scores and lower credit card debt in adulthood. We also find that the level of parental financial teaching influences the relationship between children's later educational attainment and credit scores. These findings suggest implications for initiatives promoting financial capability for parents and children.  相似文献

Morality is a prominent guide of both action and perception. We argue that non-emotional gestures can prime the abstract concept of honesty. Four studies demonstrated that the emblematic gesture associated with honesty (putting a hand on one’s heart) increased the level of honesty perceived by others, and increased the honesty shown in one’s own behavior. Target persons performing this gesture were described in terms associated with honesty, and appeared more trustworthy to others than when the same targets were photographed with a control gesture. Persons performing the hand-over-heart gesture provided more honest assessments of others’ attractiveness, and refrained from cheating, as compared to persons performing neutral gestures. These findings suggest that bodily experience associated with abstract concepts can influence both one’s perceptions of others, and one’s own complex actions. Further, our findings suggest that this influence is not mediated by changes in affective states.  相似文献

In the current study, a curvilinear association was examined between differential parenting and children's social understanding as measured using standardized assessments and behavioral observations. Social understanding was comprised of theory‐of‐mind and behavior indicating understanding of others’ minds (i.e., cognitive sensitivity and internal state talk and reasoning during sibling interactions). Data came from a community sample of 372 children (51.6% males; M age = 5.57, SD = 0.77), their younger siblings (M age = 3.14, SD = 0.27), and their mothers who were observed in their homes. We hypothesized that in families with higher levels of differential parenting, both favored and disfavored older siblings would display poorer social understanding, but that disfavored children would be more negatively impacted. Results from a hierarchical regression analysis indicated an inverse linear effect, rather than a curvilinear relationship, between being favored by mother and siblings’ social understanding. Specifically, disfavored older children showed higher levels of social understanding when interacting with their favored younger sibling. This relationship remained significant after controlling for variables such as age, SES, and language. Findings suggest that differential parenting plays a role in children's ability to understand others.  相似文献
