This study uses survey data collected from members of the International Economic Development Council (IEDC) to assess gender differences in the perceptions of female economic developers involved in the policy process. The analysis reveals women are more likely than their male counterparts to believe access to capital serves as a barrier to economic development in the communities they serve. This finding is important because bureaucratic perceptions are anticipated to have a gendered dimension, because there is ample evidence that women-owned businesses less frequently obtain external financing than do those owned by men. This obstacle to growing a business may therefore resonate more strongly with female economic developers if their perceptions reflect experiences and socialization processes shared with the women they represent. Results of an ordinal logistic regression model support this contention and contribute to the study of economic development and the role of women in the policy process.  相似文献

Business planning is a popular managerial practice, especially in the SME context. Yet, literature presents diverging perspectives regarding business planning and the role it fulfills for the individuals leading these organizations. To advance research, we focus on evidence regarding factors that determine whether and how individuals engage in business planning. Drawing on human capital concepts and the theory of planned behavior, we scrutinize how education and different prominent work experience types influence business planning behaviors. We use meta-analysis to aggregate data on 8095 observations leading SMEs from 31 independent data sets. We find critical differences in planning behaviors relating to human capital types, as well as to whether individuals engage in substantive planning processes or the specific preparation of a formal business plan. Implications of our findings for research on business planning are discussed.  相似文献

The authors feel that Japanese personnel and training methods need to be examined from a specifically personnel and training viewpoint and their article represents their analysis and conclusions based on discussions with a variety of large and medium size companies and with individuals. Their study had three main objectives—to understand how Japanese policies contribute to their economic success; to assess the effect of cultural factors; and to consider how Japanese practices might be applied to the U.K.  相似文献

Markowitz (Journal of Political Economy 60:151–158, 1952) identified a fourfold pattern of risk preferences in outcome magnitude: When outcomes are large, people are risk averse in gains and risk seeking in losses, but risk preferences reverse when the outcomes are small, with people exhibiting risk seeking in gains and risk aversion in losses. This fourfold pattern was not addressed by either version of prospect theory (Kahneman and Tversky Econometrica 47:363–391, 1979; Tversky and Kahneman Journal of Risk and Uncertainty 5:297–323, 1992). We show how prospect theory can accommodate the pattern by combining an overweighting of low probabilities with a decreasingly elastic value function. We then examine the performance of prospect theory with two decreasingly elastic value functions: Prospect theory performs better, both quantitatively and qualitatively, with a normalized logarithmic value function than with a normalized exponential value function. We discuss several issues, and speculate about why Tversky and Kahneman did not address Markowitz’s fourfold pattern.  相似文献

Consider the random sampling of a discrete population. The observations, as they are collected one by one, are enhanced in that the probability mass associated with each observation is also observed. The goal is to estimate the population mean. Without this extra information about probability mass, the best general purpose estimator is the arithmetic average of the observations, XBAR. The issue is whether or not the extra information can be used to improve on XBAR. This paper examines the issues and offers four new estimators, each with its own strengths and liabilities. Some comparative performances of the four with XBAR are made.The motivating application is a Monte Carlo simulation that proceeds in two stages. The first stage independently samples n characteristics to obtain a configuration of some kind, together with a configuration probability p obtained, if desired, as a product of n individual probabilities. A relatively expensive calculation then determines an output X as a function of the configuration. A random sample of X could simply be averaged to estimate the mean output, but there are possibly more efficient estimators on account of the known configuration probabilities.  相似文献

Abstract

Objective: “Pregaming”—drinking alcohol prior to going out—is believed to be common, yet empirical examinations are scarce. In this study, we examined who is at risk for pregaming, consequences resulting from it, and motives behind it. Participants: Participants (N = 159, 52% female) were drinkers, aged 18 to 24, recruited from introductory psychology classes. Methods: In 2005 and 2006, interview measures of drinking and pregaming and self-report demographic, motivational, and reasons for pregaming measures were administered. Results: Two-thirds of students pregamed. Younger age, but not Greek affiliation, was associated with heavier pregaming drinking. We found minimal support for the prediction of pregaming by general drinking motives. Specific reasons for pregaming were identified, including saving money and obtaining alcohol when under 21. Conclusions: Findings highlight the risk associated with pregaming, due to selection effects and to event characteristics. The unique reasons for pregaming must be further understood and addressed in targeted interventions.  相似文献

ABSTRACT

Objective: The Circle of Six (Co6) phone application (app), winner of the White House's Apps Against Abuse Challenge, seeks to incorporate friends into sexual victimization risk reduction. Despite its growing presence on college campuses, the feasibility/acceptability of the app to college women is unknown. This mixed methods study sought to fill this gap. Participants: College women (n = 44) participated in summer/fall 2015. Methods: Participants completed questionnaires, used the Co6 app for 2 months, and returned to report their experiences. Results: Consistent with the app's aim, women reported greater intentions to help friends versus strangers in sexually aggressive situations. However, app use was low over follow-up. Reasons women gave for not using the app included redundancy with existing smart phone features and discomfort with group messaging. Some saw the app as an emergency only resource. Conclusions: The Co6 app may not meet the real world needs of college women.  相似文献

U.S. racial and ethnic populations can be defined by a number of census questions—race/ethnicity, ancestry, place of birth, and/or language—but little is known about how using alternative definitions of identity affect the size and characteristics of different groups. This article examines this question using combined data from the 1 % and 5 % Public Use Microdata Samples in census 2000, using Mexicans and Arabs as case studies. The analysis uses the standard method of classifying these groups (Hispanic origin and Arab ancestry) as a baseline to explore differences across the range of possible permutations of ethnic identity. In the Arab case, persons captured using alternative definitions of identity (Arabic language at home and/or born in an Arab country) are lesser educated, more likely to be in poverty, and more likely to identify as non-white or multi-racial than the Arab population as a whole. In contrast, persons in the Mexican alternative definition group (Mexican ancestry and/or born in Mexico) are more highly educated, less likely to be in poverty, and more likely to identify as white than the Mexican population as a whole. The article concludes with research and policy implications of these findings.  相似文献
