Incumplimiento del salario mínimo en Europa central y oriental

En este estudio se analiza el incumplimiento del salario mínimo durante el periodo 2003–2012 en diez países de Europa central y oriental con salario mínimo obligatorio nacional. A partir de los datos de EU‐SILC y la metodología propuesta por Bhorat, Kanbur y Mayet (2013), se cuantifica la incidencia y magnitud del incumplimiento. Se realizan análisis de regresión sobre determinantes individuales, laborales y macroeconómicos. Aunque la incidencia permanece relativamente baja, los trabajadores a los que se dirigen las políticas de salario mínimo parecen los más expuestos a su incumplimiento. Con el tiempo, una mayor incidencia se asocia a una razón más alta entre salario mínimo y salario medio.     

Multinomial distributions applied to random sampling of particulate materials

When sampling a batch consisting of particulate material, the distribution of a sample estimator can be characterized using knowledge about the sample drawing process. With Bernoulli sampling, the number of particles in the sample is binomially distributed. Because this is rarely realized in practice, we propose a sampling design in which the possible samples have a nearly equal mass. Expected values and variances of the sample estimator are calculated. It is shown that the sample estimator becomes identical to the Horvitz–Thompson estimator in the case of a large batch-to-sample mass ratio and a large sample mass. Simulations and experiments were performed to test the theory. Simulations confirm that the round-off error due to the discrete nature of particles is negligible for large sample sizes. Sampling experiments were carried out with a mixture of PolyPropylene (PP) and PolyTetraFluorEthylene (PTFE) spheres suspended in a viscous medium. The measured and theoretical variations are in good agreement.     

Performance appraisal and culture: practice and attitudes in Hong Kong and Great Britain

This article compares the practice of and attitudes towards performance appraisal for managerial and professional staff in Hong Kong and Britain, and considers the extent to which actual practice and employee preferences are in alignment. Findings suggest that appraisal may be more widespread in Hong Kong than in Britain. However, British appraisal tends to be more participative and to place greater emphasis on discussing objectives, development and career plans. Hong Kong appraisals appear to be more directive and Hong Kong respondents perceive a higher level of 'negative' appraiser behaviour. In spite of this, Hong Kong respondents show if anything slightly more confidence in the utility of appraisal than do British respondents. They show stronger support for appraisal's use for reward and punishment and less support for the objectives-setting and training and development uses than do the British sample. Hong Kong respondents are more likely than their British counterparts to favour involving a more senior manager in appraisal, and they are less likely to prefer more frequent appraisals. There was little evidence that Hong Kong respondents had a stronger preference for group-based appraisal criteria, although they did show more support than the British sample for the use of personality as a basis for appraisal. Overall, the suggestion is that appraisal has been adopted in Hong Kong organizations but that the practice of appraisal has been adapted to suit the cultural characteristics of the society.     

Narrative construction of expatriate experience and career cycle: discursive patterns in Finnish stories of international

Expatriate experience is not only a disconnected occasion for cross-cultural anxiety and adjustment but also an important event in the process of self-development and learning. Following this view and arguing for a discursive approach, the paper focuses on ways in which expatriates themselves tell and interpret their development and movement across expatriate career cycle. Meaning systems connecting expatriate job with previous and following work experiences in career stories of Finnish engineers and managers were identified using a combination of narrative and discourse analysis. No evidence was found of an autonomous expatriate discourse but, in contrast, expatriate career cycle was narrated using available organizational repertoires of development and career. Describing and discussing the meaning-making properties of three identified discourses - bureaucratic, occupational and enterprising - the paper emphasizes the organizational environment of expatriate experience while acknowledging the limits of these contemporary career vocabularies in addressing individual learning and change in cross-cultural settings.     

Internet professionals: job skills for an on-line age

The paper explores the increasing popularity of the Internet technology Singapore. It argues that the diffusion of Internet technology to South-East Asia would create new duties and responsibilities for human resource (HR) managers. One such duty is the identification of the skills which professional Internet staff would need to perform their work effectively in organizations. Using a triangulation research method, empirical study has identified the new professional Internet jobs which have emerged the IT industry in Singapore and the skills that professional Internet personnel require do their jobs effectively. Analysis of the findings indicates that professional Internet skills involve both technical and creative abilities and that, in explaining or defining professional Internet skills, it is necessary to use both the technical and the social conceptions of skill. This argument is based on the view that the creative skills include tacit skills so that a definition based solely on the technical conception of skill cannot capture the various dimensions of Internet skills. The implications of the research findings for human resource managers are raised.     

Cultural Economy Planning in Creative Cities: Discourse and Practice

While a growing body of research analyses the functional mechanisms of the cultural or creative economy, there has been little attention devoted to understanding how local governments translate this work into policy. Moreover, research in this vein focuses predominately on Richard Florida's creative class thesis rather than considering the wider body of work that may influence policy. This article seeks to develop a deeper understanding of how municipalities conceptualize and plan for the cultural economy through the lens of two cities held up as model ‘creative cities’ — Austin, Texas and Toronto, Ontario. The work pays particular attention to how the cities adopt and adapt leading theories, strategies and discourses of the cultural economy. While policy documents indicate that the cities embrace the creative city model, in practice agencies tend to adapt conventional economic development strategies for cultural economy activity and appropriate the language of the creative city for multiple purposes.     

Input/output ranges and performance: an examination of US machine tool producers

Despite the establishment of high-tech multinational enterprises (MNEs) in Ireland since the late 1950s, the country did not succeed in closing the technological gap with most of its EU counterparts. The weak National System of Innovation (NSI), and in particular low business and government R&D levels, combined with a lack of research and technology linkages between MNEs and indigenous firms, explain these poor results. However, the Shannon region in the West of the country presents some specific institutional characteristics that could theoretically make the region a strong technological enclave. The various actors in the region - i.e. the administrative, financial, political and research institutions, as well as the business organizations - have indeed infused a new type of economic development. After a brief review of the available concepts and models articulated around these actors and their interrelationships, the paper analyses whether the Shannon region, taken as an illustrative example, mirrors a specific economic and technological localized setting. The study is based on a survey of indigenous and foreign firms.     

Sixty years of discrimination and diversity research in human resource management: A review with suggestions for future research directions

This article reviews discrimination and diversity research published in Human Resource Management (HRM) over the past 60 years. While discrimination and diversity are very different constructs, it is often informative to study them together, because when people recognize each other's diversity, this can result in bias, stereotyping, and discrimination. We conducted bibliographic searches for terms related to discrimination and diversity as well as a manual search through every title and abstract published in HRM over the last 60 years to assess article relevance. The search resulted in 135 research articles with 136 unique studies (i.e., samples) which are reviewed in this article. Sex and race are the demographics that have been examined the most in HRM, while religion has been examined the least. Moreover, the number of studies examining lesbian, gay, bisexual, transgender, and queer (LGBTQ) employees in the workplace in HRM has grown quickly within the past 10 years, culminating in a recent meta‐analysis. Our review looks at some of the earliest research published, the most recent research published, and the overall trends we identified in the research over the years for both discrimination and diversity articles. We then make future research suggestions and recommendations to advance the study of discrimination and diversity in the coming years.

Sister Communities: Rejecting Labels of Informality and Peripherality in Vanuatu

Some labels have dire consequences. This article takes issue with the labels commonly used to describe the physical and social location of communities living on the edge of Port Vila, Vanuatu—labels that position communities for eviction by entrenching tropes of informality and peripherality into how they are seen and represented. Such terms include informal, settlement, informal settlement, squatter and peri-urban. Based on interviews with around 100 people and two years of ethnographic engagement with urban communities in Port Vila, Vanuatu, I critique the language of policy against the lived experience of those at the urban edge. I use Bourdieu's articulation of power as an accumulation of symbolic capital that enables one to speak the world into being. I conclude that the language of policies and plans is reflective of a dominant discourse in urban studies and international aid, and non-reflective of the experience and identities of people living at the urban edge. My interviewees and interlocutors maintain their identities as sister communities—as places grounded in the formality of customary tenure, and as part of the city rather than outside it.
