To analyse the role of self-efficacy in goal setting in public administrations, this study combines goal-setting theory, public service motivation literature and cognitive theory. Using partial least squares structural equation modelling (PLS-SEM), survey data from 105 German civil servants are analysed. The results underline the role of goal setting (represented by goal difficulty and specificity) in determining the self-efficacy of public servants. Public service motivation and goal specificity both increase public servants’ work performance; however, the effects of goal difficulty are negatively mediated by the employee’s self-efficacy. That finding reflects the central role of self-efficacy, which should not be ignored in the goal-setting processes of public administrations. 相似文献

This article presents a flood risk analysis model that considers the spatially heterogeneous nature of flood events. The basic concept of this approach is to generate a large sample of flood events that can be regarded as temporal extrapolation of flood events. These are combined with cumulative flood impact indicators, such as building damages, to finally derive time series of damages for risk estimation. Therefore, a multivariate modeling procedure that is able to take into account the spatial characteristics of flooding, the regionalization method top‐kriging, and three different impact indicators are combined in a model chain. Eventually, the expected annual flood impact (e.g., expected annual damages) and the flood impact associated with a low probability of occurrence are determined for a study area. The risk model has the potential to augment the understanding of flood risk in a region and thereby contribute to enhanced risk management of, for example, risk analysts and policymakers or insurance companies. The modeling framework was successfully applied in a proof‐of‐concept exercise in Vorarlberg (Austria). The results of the case study show that risk analysis has to be based on spatially heterogeneous flood events in order to estimate flood risk adequately. 相似文献

Within the debate about the future of the welfare state a guaranteed social minimum income is often discussed as an alternative to the current social security system. One objection to such a proposal argues that a social minimum income lacks social acceptance and normative recognition. Starting from the thesis that the standard instruments of survey research have little to offer for giving a detailed account of the attitudes towards a social minimum, we deploy the more complex method of Factorial Survey Design. The study sample consists of 121 employed persons. Within the study, the focus is on the criteria used and the differentiations made when people are asked to evaluate a just minimum income. It can be shown that a uniform and flat-rate social minimum possesses less legitimacy than a transfer system that differentiates entitlements according to the beneficiaries relation to the employment sphere and certain need criteria. In addition, we find support for the idea of low income subsidies as suggested by the negative income concept. Though the results give evidence of the normative attraction of a social minimum, it is also apparent that the social judgments of the respondents are influenced by in the normative principles of the existing social security arrangements. 相似文献

人的因素是高校思想政治工作的核心因素 ,基于这一客观实际 ,高校思想政治工作应当树立起以人为本的理念 ,并将其置于核心的地位。以人为本的理念既是一种价值观 ,对高校思想政治工作起着价值导向、判断和调控作用 ;又是一种方法论 ,要求高校思想政治工作要从人的实际出发 ,并充分发挥人的作用。对于高校思想政治工作而言 ,树立并实践以人为本的理念具有现时的紧迫性 ,本文主张从观念、环境创造和实践渗透三个着眼点去促进以人为本的理念与高校思想政治工作的结合 相似文献

Barro-type endogenous growth models propose a nonmonotonic relationship between productive public spending and growth. Under this so-called nonlinearity hypothesis the size and direction of growth effects due to an increase in public spending depend on the share of public spending in GDP. Employing German time-series data we examine the validity of the nonlinearity hypothesis. We estimate growth effects by using models whose coefficients are allowed to vary with the share of public spending in GDP. Our results support the hypothesis for public consumption but not for public investment data. (JEL H54 , E62 , C22 ) 相似文献
