Perpetrator and incident characteristics were studied in regard to incidents of emotional, physical, and sexual mistreatment of older adults (age 60+) in a national sample of older men and women. Random digit dialing across geographic strata was used to compile a nationally representative sample; computer assisted telephone interviewing was used to standardize collection of demographic, mistreatment, and perpetrator and incident characteristics data. The final sample size consisted of 5,777 older adults. Approximately one in ten adults reported at least one form of mistreatment, and the majority of incidents were not reported to authorities. Perpetrators of physical mistreatment against men had more “pathological” characteristics compared to perpetrators of physical mistreatment against women. Perpetrators of physical mistreatment (compared to emotional and sexual mistreatment) also evidenced increased likelihood of legal problems, psychological treatment, substance use during incident, living with the victim, and being related to the victim. Implications for future research and social policy are discussed. 相似文献

Internationalization, innovation and entrepreneurship: business models for new technology-based firms 总被引:3,自引:0,他引:3

New technology-based firms, particularly those that develop their business around a new technological platform, are likely to be impacted by globalization, in terms of both pace of innovation and pressure of competition. For these firms, strategic decisions and growth processes are characterized by a deep inter-relationship amongst the processes of internationalization, innovation and entrepreneurship; processes which have tended to be examined independently in distinct bodies of literature. In practice strategic decisions concern each of these processes and address issues such as organizational boundaries, location of the operational activities, what activities to focus on and selection of value partners. The business model by which firms operate needs also to accommodate the spatial dimensions indicated by globalization; and the emergence of global technology markets. Little is known to date about the extent to which business models accommodate or are adapted to internationalization, innovation and entrepreneurship. This paper presents a review of the business model literature from which a generic business model framework is derived, identifying and introducing the main elements of these processes as the firms?? focus, modus and locus. This contribution makes a clear distinction between the business model and the strategy concepts and highlights the relevance of location decisions??not considered by extant business model literature to date. While our discussion draws on the high technology new venture as our primary example, we believe our business model conceptualization has general applicability. 相似文献

In this paper we propose an extension of the generalized half-normal distribution studied in Cooray and Ananda (Commun Stat 37:1323–1337, 2008). This new distribution is defined by considering the quotient of two random variables, the one in the numerator being a generalized half normal distribution and the one in the denominator being a power of the uniform distribution on \((0,1)\) , respectively. The resulting distribution has greater kurtosis than the generalized half normal distribution. The density function of this more general distribution is derived jointly with some of its properties and moments. We discuss stochastic representation, maximum likelihood and moments estimation. Applications to real data sets are reported revealing that the proposed distribution can fit real data better than the slashed half-normal, generalized half-normal and Birnbaum–Saunders distributions. 相似文献

Objective. This study explores whether the earnings of U.S.‐born cross‐border workers differ from those of their U.S.‐employed counterparts. We also analyze whether the cross‐border/non‐cross‐border wage differential changed during the 1990s—a decade when U.S.‐Mexico trade intensified and the maquiladora industry expanded. Methods. Employing decennial U.S. Census data from 1990 and 2000, this article estimates earnings functions and uses wage decomposition analysis to study changes in the earnings of U.S.‐born Hispanic and non‐Hispanic cross‐border workers. Results. The number of U.S.‐native cross‐border workers, while relatively small, increased significantly between 1990 and 2000, as did their earnings. A closer examination reveals that this cross‐border earnings premium only developed among non‐Hispanics. Conclusions. These findings indicate that some U.S. natives find lucrative employment opportunities on the Mexican side of the border, which might be diminished by additional restrictions for U.S.‐born residents to easily cross back and forth into Mexico. 相似文献

This article aims to offer an ex ante evaluation of the impact of a parametric reform of the Spanish pension system that would involve increasing the reference period used to calculate benefits, an approach proposed many times by various actors in the socio‐economic field. Such gradual change may be categorized as a non‐structural reform of the pension system. This contrasts with reforms of a structural nature that have been very popular in Latin America and elsewhere, involving the creation of defined contribution individual account schemes. As regards the parametric reform proposed in this article, the main findings indicate that it would have a small but negative impact on pension income for pensioners and would reduce income distribution. 相似文献

The evaluation of social programs constitutes an important aspect in the modeling of economic policies. On the basis that the measurement of well being through subjective measures provides a broader perspective than through objective economic variables, this paper first identifies the determinants of deprivation in Spain, in monetary terms, and in non-monetary terms using satisfaction variables. In addition to establishing that the more unequal the income distribution within a group, the less income-satisfied is the individual, we find that unemployment is one of the main determinants of deprivation and satisfaction. Accordingly, we propose a reform of unemployment benefit policy that maintains individuals at the same utility level as when employed, rather than applying the current benefit system. Our policy conclusions reveal that the public budget dedicated to paying benefits to restore satisfaction levels, during the period 1994-1999, would have increased by €2,536,165.13 thousand on an average annually. It could be a desirable policy in good times but, since it increases public spending and thus public deficit, economic policy makers should decide whether it is adequate in rainy days. 相似文献

This paper reports estimates of the effects of JTPA training programs on the distribution of earnings. The estimation uses a new instrumental variable (IV) method that measures program impacts on quantiles. The quantile treatment effects (QTE) estimator reduces to quantile regression when selection for treatment is exogenously determined. QTE can be computed as the solution to a convex linear programming problem, although this requires first‐step estimation of a nuisance function. We develop distribution theory for the case where the first step is estimated nonparametrically. For women, the empirical results show that the JTPA program had the largest proportional impact at low quantiles. Perhaps surprisingly, however, JTPA training raised the quantiles of earnings for men only in the upper half of the trainee earnings distribution. 相似文献

Abstract. Moving off from the lessons of the Italian incomes policy experience of the 1980s, this paper presents a new framework to interpret the performance of incomes policy (LP) agreements and institutions, and propose new strategies for the 1990s. IP is viewed as a cooperative outcome that evolves from a non-cooperative long-term game between several players (workers, unions, firms, government, parliament, etc.), along the lines of the model drawn up by Brunetta and Carraro (1988). The paper is divided into three sections. The first summarizes the history of IP in Italy, starting from the phase of the predetermination of disinflation (1983-84). We firstly outline some of the fundamental features of recent Italian development (the “Italian model”), noting how new IP measures could be taken to create an adequate response to the new European and international deadlines. The difficulties and uncertainties that presently exist at both national and international level make the introduction of IP in new, cooperative and evolutive terms, necessary. The second section examines the various topics and new objectives of a “strategic” IP resumption, particularly relevant to the concerted action on the cost of labour, presently being discussed. The topics we consider are: the link between wage reform and IP; the recent concerted agreements reached on fiscal drag (26.1.89) and on the cost of labour (25.1 and 6.7.90); the importance of the role of productivity gain-sharing; programmed inflation and price control; indexation of gross wages and safeguarding the net wage; increase of the tax base; profit-sharing. The third and final section presents a few observations which further investigate the distribution of productivity gains between sectors and uses: how it is articulated amongst the various bargaining levels (central, sectoral or enterprise). Redistribution amongst sectors is dealt with in terms of “protected” and “unprotected” areas of the economy, showing the need of a concerted regulation at the central level. Sharing between factors and allocations presents a very different case, and is dealt with at sectoral and firm level. 相似文献

Periods of assessed learning in practice settings are common requirements for social work students worldwide. The ‘practice learning opportunity’ as it is known in the UK, and ‘tirocinio di servizio sociale’ as it is referred to in Italy, are important sites of gatekeeping in preventing unsuitable people from becoming social workers. The experience of assessing failing students in practice learning settings, however, has been found to be particularly stressful and challenging for practice educators. This article documents findings from two qualitative studies that explored field educators’ experiences of working with struggling or failing social work students in Italy and England. The study finds both similarities and differences in the narratives of the assessors from the two countries. Similarities include, unpleasant emotional experience of working with a failing student, internalisation of the students’ failing as the practice educators’ own failing, perceptions that the universities may hide negative information about students and lack of acknowledgement of the gatekeeping function inherent in the practice educator role. Differences include the level of emotionality experienced by educators, the way students are spoken about and the perceived role and responses of the university. Further comparative European research that focuses on practice education is indicated. 相似文献

The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local. 相似文献
