FEDERAL TRANSFER PAYMENTS IN AMERICA: VETERANS' PENSIONS AND THE RISE OF SOCIAL SECURITY

This paper examines the determinants of the adoption of the veterans' pension program and how it served as a prototype for the creation and administration of the federal welfare system in the United States. We provide statistical evidence in the form of an analysis of votes in the House of Representatives that state-based special interests which had supported the ongoing liberalization of the veterans' pension program provided significant support for the adoption of the Social Security Act of 1935. There is clear evidence the social security system was not adopted as a simple extension of state old-age pension programs.     

Robust estimation for linear regression with asymmetric errors

The authors propose a new class of robust estimators for the parameters of a regression model in which the distribution of the error terms belongs to a class of exponential families including the log‐gamma distribution. These estimates, which are a natural extension of the MM‐estimates for ordinary regression, may combine simultaneously high asymptotic efficiency and a high breakdown point. The authors prove the consistency and derive the asymptotic normal distribution of these estimates. A Monte Carlo study allows them to assess the efficiency and robustness of these estimates for finite samples.     

关于党与人大在国家中地位的理性分析

党政关系是政治体制改革的中心环节,党政关系之所以难分难解的根本原因之一就在于党部分地承担起本应由人大来履行的职责,所以说党政关系最重要的就是党与人大的关系。只有正确处理党与人大的关系才能从根本上克服“党政不分”的弊端。然而,正确处理党与人大的关系却是一个复杂且难度很大的问题。对党与人大在国家中地位的分析可以帮助我们更好地处理两者的关系。     

DEFINING WHO WE ARE AND WHAT WE DO: CLINICAL PRACTIVE PATTERNS OF MARRIAGE AND FAMILY THERAPISTS IN MINNESOTA

The clinical practice patterns of a representative sample of marriage and family therapists (MFTs) were studied. AAMFT clinical members from Minnesota ( N = 76 ) were surveyed for demographic characteristics, educational beckground, and practice-related issues. subjects also reported empirical data from 119 treatment cases involving 351 clients, a first in the MFT field. Among the major findings were: (a) MFTs practic relatively short-term therapy with the average case involving 11 sessions over a 4-month period; (b) therapy with families (average of 8 sessions) and couples (10 sessions) is briefer than individual therapy (14 sessions); and (c) NFTs treat a wide range of serious problems. Overall, MFT clinical practice patterns were comparable to those of other established mental health professions.     

Rota-Risk-Profile-Analysis

Abstract

In this article an update of the Rota-Risk-Profile-Analysis (RRPA) is presented. This RRPA is based on 9 rota-risk criteria that are central to a more encompassing rota theory. The RRPA allows coherent assessment of the physical and social risks of a working-time schedule (rota). comparison of schedules with one another in quantitative terms and interpretations of possible differential effects more adequately. First, a closer look at the instrument-a computer program-is taken. Afterwards the criteria and their way of implementation are discussed briefly. To get an impression of the way that RRPA functions an example will be given by applying the instrument to the working rotas from a study on shiftwork in the Netherlands.     

Dynamic Simulation as an Approach to Understanding Hurricane Risk Response: Insights from the Stormview Lab

This article investigates the use of dynamic laboratory simulations as a tool for studying decisions to prepare for hurricane threats. A prototype web‐based simulation named Stormview is described that allows individuals to experience the approach of a hurricane in a computer‐based environment. In Stormview participants can gather storm information through various media, hear the opinions of neighbors, and indicate intentions to take protective action. We illustrate how the ability to exert experimental control over the information viewed by participants can be used to provide insights into decision making that would be difficult to gain from field studies, such as how preparedness decisions are affected by the nature of news coverage of prior storms, how a storm's movement is depicted in graphics, and the content of word‐of‐mouth communications. Data from an initial application involving a sample of Florida residents reveal a number of unexpected findings about hurricane risk response. Participants who viewed forecast graphics, which contained track lines depicting the most likely path of the storm, for example, had higher levels of preparation than those who saw graphics that showed only uncertainty cones—even among those living far from the predicted center path. Similarly, the participants who were most likely to express worry about an approaching storm and fastest to undertake preparatory action were those who, ironically, had never experienced one. Finally, external validity is evidenced by a close rank‐order correspondence between patterns of information use revealed in the lab and that found in previous cross‐sectional field studies.     

Why Risk Analysis is Difficult,and Some Thoughts on How to Proceed

Risk analysis is challenged in three ways by uncertainty. Our understanding of the world and its uncertainties is evolving; indeterminism is an inherent part of the open universe in which we live; and learning from experience involves untestable assumptions. We discuss several concepts of robustness as tools for responding to these epistemological challenges. The use of models is justified, even though they are known to err. A concept of robustness is illustrated in choosing between a conventional technology and an innovative, promising, but more uncertain technology. We explain that nonprobabilistic robust decisions are sometimes good probabilistic bets. Info‐gap and worst‐case concepts of robustness are compared. Finally, we examine the exploitation of favorable but uncertain opportunities and its relation to robust decision making.

Peers,proactivity, and problem-solving: A multilevel study of team impacts on stress appraisals of problem-solving demands

ABSTRACT

To date, there is a paucity of research on team-level impacts on the individual stress appraisal process despite the recognised role of teams for solving problems. Applying a multilevel approach, this study investigates the cross-level impact of team problem prevention behaviours on employee stress appraisals of problem-solving demands. It was hypothesised that team problem prevention would moderate the individual-level relationship between problem-solving demands and stress appraisals. Data were collected from 43 work teams comprised of 192 team members including all team leaders who also provided evaluations of their team’s problem prevention behaviour. Results supported the hypothesised cross-level moderating effects on challenge appraisal, but not threat appraisal. As one of the first studies to demonstrate that stress appraisals are impacted by the group, not just by individual factors, the results support a multilevel conceptualisation of stress appraisals. The findings also highlight implications for practice, broadening the scope of possibilities for stress management interventions to utilise team-level strategies such as leadership development programmes and/or team building initiatives.
