Collegial relationships at work have become more important now that organizations increasingly use team-based work processes. Collegiality is also facing new challenges, however: more employees are meeting heavy demands beyond the workplace and making more frequent use of flexible work arrangements. This study seeks to explain the effect of employees’ family demands on collegiality and evaluates whether the use of flexible work arrangements improves or impedes collegial behaviour. Moreover, we aim to investigate collegial behaviour as an exchange process between co-workers, and therefore also take family demands and the use of flexible work arrangements by co-workers into account as predictors of employee collegiality. Based on a sample of 1114 employees from 30 organizations, the results show that when used by the employee and co-workers, flexitime decreases collegiality. Collegiality is decreased when the employee has young children, but increased when co-workers have older children. The implications of these findings for HR practices are discussed.  相似文献

We extend the class of dynamic factor yield curve models in order to include macroeconomic factors. Our work benefits from recent developments in the dynamic factor literature related to the extraction of the common factors from a large panel of macroeconomic series and the estimation of the parameters in the model. We include these factors in a dynamic factor model for the yield curve, in which we model the salient structure of the yield curve by imposing smoothness restrictions on the yield factor loadings via cubic spline functions. We carry out a likelihood-based analysis in which we jointly consider a factor model for the yield curve, a factor model for the macroeconomic series, and their dynamic interactions with the latent dynamic factors. We illustrate the methodology by forecasting the U.S. term structure of interest rates. For this empirical study, we use a monthly time series panel of unsmoothed Fama–Bliss zero yields for treasuries of different maturities between 1970 and 2009, which we combine with a macro panel of 110 series over the same sample period. We show that the relationship between the macroeconomic factors and the yield curve data has an intuitive interpretation, and that there is interdependence between the yield and macroeconomic factors. Finally, we perform an extensive out-of-sample forecasting study. Our main conclusion is that macroeconomic variables can lead to more accurate yield curve forecasts.  相似文献

This article describes the development of an instrument to measure the quality of managerial learning on the job. The instrument can be used to analyse the quality of the individual learning process on the job. The literature shows that two factors determine the quality of the learning process: the learning potential of the job context and the way in which the manager approaches their work. So the instrument has two components. The first component measures the four types of work experience that offer potential opportunities for individual learning. These are transitions, task-related characteristics, obstacles and support. The second component, the so-called learning behaviour, analyses the way the individual approaches the potential learning opportunities present in the job. This can also be divided into four categories: emergent learning, planned learning, instruction-oriented learning and meaning-oriented learning. Based on these two components, an instrument has been developed to measure the quality of learning on the job. This has been shown to be valid and reliable in a sample of European managers.  相似文献

Neil Smith argues that in the last two decades gentrification has become a generalized global urban phenomenon. His theory is at a high level of abstraction, as it links urban gentrification to globalization, financial capitalism and neoliberalization. With these global processes, all cities have experienced ‘third wave’ gentrification. The theory, however, leaves little room for variegations of gentrification, apart from characterizing geographical differences as idiosyncrasies or as minor variations. This downplays the role of intervening mechanisms that impinge upon the pursuit and social outcomes of gentrification. This article aims to amend abstract theory by looking at Amsterdam from a historical institutional perspective. In Amsterdam, gentrification was particularly made possible by a process of neoliberalization within the housing system. However, as institutional change is incremental and based on layering and conversion, many older institutional arrangements remain in place. These arrangements tend to slow gentrification and assuage social consequences. Nevertheless, neoliberal modifications to the housing system have been accelerating the pursuit of gentrification. Current policies will very likely lead to exclusionary displacement.  相似文献

With the increasing scarcity of natural resources, the ability to maintain quality standards during resource-scarce times becomes more critical for business performance. Theories on managing resource scarcity cannot be easily tested in contexts where resources are still abundant. This study therefore turns to an emerging market context in which natural resource availability naturally varies strongly between seasons, namely, that of Ethiopian pastoralists who for many generations learned to adapt to natural resource scarcity. Central to our theory is the natural resource deployment capability, which is the ability of a business to make efficient and effective use of available resources to maintain business performance during resource-scarce times. Using three-wave longitudinal data from 120 pastoral family-based livestock businesses, the study shows that when resources are scarce or extremely scarce, market knowledge helps to better deploy the scarce natural resources, leading to higher product quality. The findings imply that businesses with a better understanding of markets have stronger natural resource deployment capability. The lesson for businesses that are confronted with approaching resource scarcity is therefore to strengthen their ability to deploy resources efficiently and effectively by strengthening their market knowledge in which such capability is rooted.  相似文献

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.  相似文献

With the development of an MCMC algorithm, Bayesian model selection for the p 2 model for directed graphs has become possible. This paper presents an empirical exploration in using approximate Bayes factors for model selection. For a social network of Dutch secondary school pupils from different ethnic backgrounds it is investigated whether pupils report that they receive more emotional support from within their own ethnic group. Approximated Bayes factors seem to work, but considerable margins of error have to be reckoned with.  相似文献

How did the biological standard of living develop in Indonesia during colonial times? Did it increase substantially after decolonization? In our study, we use four sets of anthropometric data to construct time series of average human height since the 1770s. The paper observes a significant decline in heights in the 1870s, followed by only modest recovery during the next three decades, both of which are related to a sequence of disasters. Average heights increased from the 1900s and accelerated after World War II. The World Economic Crisis, the Japanese occupation and the war of independence in the 1930s and 1940s constituted a difficult period. Average height growth thereafter is related to improvements in food supply and the disease environment, particularly hygiene and medical care.  相似文献

In the Choice Questionnaire (Neijens et al. 1992) respondents have to choose between several policy options. Within this questionnaire they are provided with information about the consequences of each option. Until now, only indirect evidence as to whether or not respondents base their preferences on the information provided was available and plausible alternative explanations for the Choice Questionnaire's effect could not be ruled out. In the present study, we demonstrate that Choice Questionnaire respondents do base their preferences on the information provided: different information resulted in significantly different choices.  相似文献

Almost every theory of human behavior is based upon some assumption of rationalty. Such an assumption is commonly believed to be necessary in order to distinguish rational behavior, which is, from non-rational behavior, which is not amenable to scientific investigation. This article presents a thorough re-examination of this assumption, an inquiry which turns out to raise all the central issues of both the methodology and the theory of behavioral inquiry generally. It leads to the somewhat surprising conclusion that the notion of rationality does not have any meaningful role to play in behavioral inquiry, and that there is no sense in distinguishing rational from non-rational or irrational behavior. It also shows that the generalization of the utility notion in terms of information makes it into a much more powerful and subtle tool of analysis than it commonly appears to be taken for.  相似文献
