This prospective, longitudinal study investigated the moderating role of pubertal timing on reciprocal links between adolescent appraisals of parent–child relationship quality and girls' (N=1,335) and boys' (N=1,203) cigarette and alcohol use across a 12‐month period. Reciprocal effects were found between parent–child relations and on‐time maturing boys and girls' cigarette and alcohol use, after estimating stability in these constructs across time. Parent–child relationship quality was associated with increased alcohol use 12 months later for early maturing girls. Cigarette and alcohol use were associated with increased problems in the parent–child relationship for late maturing girls. No effects were observed for early and late maturing boys in the pathways between parent–child relationship quality and substance use. Pubertal timing moderated the pathway linking parent–child relationship quality with cigarette use 1 year later such that the association was stronger for late maturing girls compared with early and on‐time maturing girls. The findings indicate interplay between the psychosocial aspects of maturation, family relationships, and adolescent substance use and highlight possible gender‐specific influences. 相似文献

This study identified factors influencing family business survival using National Family Business Panel and Spatial Hazard
Events and Losses data. Sustainable Family Business Theory guided the use of a parametric duration model of long-term survival.
Community characteristics, family achievements, family processes during change, business and owner characteristics, and business
processes during stability affected long-term survival. Economic vulnerability of rural counties, family income from business,
hiring temporary help, business size, viewing business as a way of life, and owner experience were associated with increased
duration of business survival. Being home-based, a female owner, and customer-focused were associated with decreased duration
of survival. Some family processes and achievements increased the duration of business survival; none decreased it. 相似文献

Freedom of information laws are intended to illuminate how governments operate. However, the operations of governments increasingly involve algorithms, such as those used to recommend criminal sentencing and determine eligibility for social services. Algorithms function as ‘black boxes’ that turn inputs into outputs using processes that are often, by design, not transparent. Freedom of information laws allow one potential means for algorithmic transparency. However, whether such laws can be used to access algorithms is unclear. This research examines, in two ways, the availability of government algorithms to the public. First, this study examines laws, regulations, advisory opinions, and court rulings relevant to the disclosure of algorithms. The second part of this study analyzes actual responses by US government agencies to Freedom of Information Act requests for algorithms. This study concludes that governmental policies and practices related to algorithmic disclosure are inconsistent. Such inconsistencies suggest a need for better mechanisms to hold government algorithms accountable. 相似文献

Tax data suggest that the population of adult dependents—adults relying on the support of others for the majority of their financial needs—has more than doubled over the last decade. However, little is known about how taxes affect the labor supply decisions of this population. This paper provides an initial investigation, studying the impact of the Earned Income Tax Credit (EITC) expansions of the early 1990s on the labor supply of adult dependents living with their relatives. I find that dependent individuals who were not a part of the nuclear family responded to the EITC expansions, increasing labor force participation by about 5 percentage points. For adult children, I show that the absence of a net response is likely due to an unexpected consequence of the EITC: expanded family credits led to a decrease in their labor force participation. 相似文献

Local emergency managers are charged by the U.S. Department of Homeland Security to increase the number of community members with emergency plans and kits. This outcome remains unrealized in part based upon in-depth interviews with 37 emergency managers in eight states revealing that emergency managers conceptualize communication as dissemination rather than as a process of research and evaluation. This study calls for local emergency managers to conduct outcome evaluations of risk communication campaigns to increase public participation. 相似文献

The Rohingya have faced discriminatory policies and actions by the Myanmar government since independence in 1948, with many within the state seeing them as foreigners. This paper uses historical process tracing from pre-British colonialism to present day to argue that the persistent persecution of the Rohingya stems from the divergent experiences under British colonialism for the Rohingya and majority Burman population and, as a result of this, Burmese national identity forming around the dominant Burman ethnic group and the Buddhist faith. The government following independence, then, institutionalized this national identity, excluding the Rohingya as a part of the nation and denying their identity, arguing instead that they are “illegal Bengali immigrants”. As shown through this case study, the resiliency of these anti-Rohingya policies and attitudes within the Myanmar government through successive regime changes is a result of national identity being defined as both Burman and Buddhist, which remained constant. It also helps to explain how the political opening provided by the democratization process resulted in a number of anti-Muslim and anti-Rohingya operations by Buddhist monks and other Buddhist nationalists, government policies, and even military operations. 相似文献

We address the issue of performing testing inference in the class of zero-inflated power series models. These models provide a straightforward way of modelling count data and have been widely used in practical situations. The likelihood ratio, Wald and score statistics provide the basis for testing the parameter of inflation of zeros in this class of models. In this paper, in addition to the well-known test statistics, we also consider the recently proposed gradient statistic. We conduct Monte Carlo simulation experiments to evaluate the finite-sample performance of these tests for testing the parameter of inflation of zeros. The numerical results show that the new gradient test we propose is more reliable in finite samples than the usual likelihood ratio, Wald and score tests. An empirical application to real data is considered for illustrative purposes. 相似文献

The FDA released the final guidance on noninferiority trials in November 2016. In noninferiority trials, validity of the assessment of the efficacy of the test treatment depends on the control treatment's efficacy. Therefore, it is critically important that there be a reliable estimate of the control treatment effect—which is generally obtained from historical trials, and often assumed to hold in the current setting (the assay constancy assumption). Validating the constancy assumption requires clinical data, which are typically lacking. The guidance acknowledges that “lack of constancy can occur for many reasons.” We clarify the objectives of noninferiority trials. We conclude that correction for bias, rather than assay constancy, is critical to conducting valid noninferiority trials. We propose that assay constancy not be assumed and discounting or thresholds be used to address concern about loss of historical efficacy. Examples are provided for illustration. 相似文献

Earned income tax credit (EITC) benefit income is paid out in a lump‐sum around tax time. We investigate whether savings and debt among EITC‐eligible families reflect the timing of payments. Using nationally representative, individual‐level data on self‐reported debt and savings outcomes, we search for differences in monthly behavior between EITC‐eligible and ‐ineligible households. We find evidence that credit card and unsecured debt holding among EITC‐eligible families reflects the timing of the EITC, with low debt levels at tax time relative to other months. Debt holding among ineligible families with children does not exhibit a similar pattern. We find limited evidence of intrayear patterns in savings behavior among EITC‐eligible families.
