The purpose of this study is to highlight the application of sparse logistic regression models in dealing with prediction of tumour pathological subtypes based on lung cancer patients'' genomic information. We consider sparse logistic regression models to deal with the high dimensionality and correlation between genomic regions. In a hierarchical likelihood (HL) method, it is assumed that the random effects follow a normal distribution and its variance is assumed to follow a gamma distribution. This formulation considers ridge and lasso penalties as special cases. We extend the HL penalty to include a ridge penalty (called ‘HLnet’) in a similar principle of the elastic net penalty, which is constructed from lasso penalty. The results indicate that the HL penalty creates more sparse estimates than lasso penalty with comparable prediction performance, while HLnet and elastic net penalties have the best prediction performance in real data. We illustrate the methods in a lung cancer study. 相似文献

An empirically derived model of cyclical board behavior holds that following a nonrecurring founding period, a board typically progresses through a sequence of three distinct operating phases and then experiences a crisis that initiates the whole sequence over again. During each cycle, board members become progressively less interested in the agency's mission and programs and more interested in the board's bureaucratic procedures and the agency's reputation for success in the community. Although the sequence of phases is predictable, the timing of them is not. As a conceptual framework, the model integrates the results of a variety of valuable, but otherwise unrelated, studies of governing board behavior. The cyclical model can also be used as a diagnostic tool that can enable a board member, executive director, consultant, foundation officer, or public funder to analyze quickly a particular board's perspective and potential. 相似文献

Mortality among elder abuse victims in rural Malaysia: A two-year population-based descriptive study

Our study aims at describing mortality among reported elder abuse experiences in rural Malaysia. This is a population-based cohort study with a multistage cluster sampling method. Older adults in Kuala Pilah (n = 1,927) were interviewed from November 2013 to May 2014. Mortality was traced after 2 years using the National Registration Department database. Overall, 139 (7.2%) respondents died. Fifteen (9.6%) abuse victims died compared to 124 (7.0%) not abused. Mortality was highest with financial abuse (13%), followed by psychological abuse (10.8%). There was a dose-response relationship between mortality and clustering of abuse: 7%, 7.7%, and 14.0% for no abuse, one type, and two types or more, respectively. Among abuse victims, 40% of deaths had ill-defined causes, 33% were respiratory-related, and 27% had cardiovascular and metabolic origin. Results suggest a link between abuse and mortality. Death proportions varied according to abuse subtypes and gender. 相似文献

The study purpose was to develop and pilot an undue influence screening tool for California’s Adult Protective Services (APS) personnel based on the definition of undue influence enacted into California law January 1, 2014. Methods included four focus groups with APS providers (n = 33), piloting the preliminary tool by APS personnel (n = 15), and interviews with four elder abuse experts and two APS administrators. Social service literature—including existing undue influence models—was reviewed, as were existing screening and assessment tools. Using the information from these various sources, the California Undue Influence Screening Tool (CUIST) was developed. It can be applied to APS cases and potentially adapted for use by other professionals and for use in other states. Implementation of the tool into APS practice, policy, procedures, and training of personnel will depend on the initiative of APS management. Future work will need to address the reliability and validity of CUIST. 相似文献

The voices of people experiencing poverty are underrepresented in social work research, public policy development, and practice interventions. This study explored the social class attributions of clients receiving poverty-related services through qualitative interviews. Findings reveal dynamic contributions of individual, environmental, and structural factors of social class positioning and significant stress and stigmatization associated with experiencing economic hardship. Participants indicate a sense of lived contradiction, viewing social class to be the result of fate while simultaneously endorsing individualistic attributions of poverty. Results have implications for social work research and practice, as well as poverty-related policy and program development. 相似文献

A key goal in youth studies is to gain holistic understandings of what it means to be young. However, a significant impediment to achieving this has been the tendency of youth studies to develop along siloed and stratified subfields. In keeping with the goal of creating more productive dialogue between subfields in youth studies, this paper examines the intersections between research in youth citizenship and youth transitions to consider the fresh insights and cross fertilisations that such an analysis may yield. This examination reveals a sense of dissatisfaction in both subfields with traditional normative and linear models of citizenship and transitions which rely on step-wise and sequential notions of time. In response, the paper advances a new research agenda which posits more temporally, spatially and relationally-sensitive understandings of youth citizenship and transition. Drawing on Ingold (2007. Lines: A brief history. London: Routledge), this agenda proposes the use of three alternative metaphors – genealogical, wayfaring and threads – which could hold the potential to unsettle the normativity and linearity of previous youth transitions and citizenship frameworks, and thus provide deeper insights into what it means to live and to be young citizens in times of transition. 相似文献

This article evaluates a program between students at a primary school and aged care residents. The aim of the program was to increase respect and appreciation between the groups. Visiting programs between children and the elderly are well documented, and assumes that the contact will benefit both groups. However the research is contradictory. To ensure that this program was achieving its goals, pre-post test data using the Children’s Perceptions of Aging and Elderly test was collected. Significant improvements in attitude were seen in two items. Overall, there was an improvement in attitude in 12 of the 18 instrument items. 相似文献

Most cities, counties, and neighborhoods are not designed for an aging population. By providing a range of services to all residents, Lifelong Communities allow individuals to age in place. Although the Lifelong Communities Initiative is based on established guiding principles, little information exists regarding the realities of moving from policy to implementation. The Atlanta Regional Commission conducted a case study in Mableton, Georgia, and found successful implementation requires a combination of support from local citizen groups and government. The Atlanta Regional Commission is replicating these best practices in other communities and providing support to those aspiring to launch or expand Lifelong Communities. 相似文献
