Together alone: a group-based polarization measurement

Quality & Quantity - The growing polarization of our societies and economies has been extensively studied in various disciplines and is subject to public controversy. Yet, measuring...     

Nexus between economic sanctions and inflation: a case study in Iran

Conventional studies have applied dummy variables to analyse the relationship between economic sanctions and inflation while we construct an index which is called Trade-Financial Sanctions (TF index). TF Index is a liner combination of indices which includes trade openness and foreign investment by applying the principal component model. Through the TF index and market exchange rate the impact of economic sanctions on inflation is analysed in the three phases of sanctions; free sanctions, heavy sanctions, and light sanctions. The results illustrate that the TF index decreases inflation when the Iran’s economy experiences free sanctions or light sanctions relative to when the economy is in heavy sanctions. Heavy sanctions create instability in the market exchange rates and widening the gap between the market and the official exchange rates. Furthermore, economic sanctions increase expected inflation among the people and drive higher inflation. Therefore, these results suggest that the government should work more seriously to solve the main obstacles of trade and investment inflows imposed by the economic sanctions.     

National culture, networks and ethnic entrepreneurship: A comparison of the Indian and Chinese immigrants in the US

This paper uses a combination of national cultural frameworks and social capital theory to explain the formation and management of entrepreneurial ventures among immigrant communities. The varying rates of venture formation and performance among different ethnic groups points to the role that the different dimensions of culture play in how immigrants use their social networks to start such firms. We use the specific example of the Indian and Chinese communities in the US to demonstrate this effect and explain how businesses created by members of these communities could have potentially different ways of starting and operating that can be directly traced to the differences in cultural orientation of their owners. What emerges can be summarized as: (a) different immigrant communities have different ways of accumulating and using social capital in starting and managing their ethnic ventures; (b) these dissimilarities manifest themselves in variations in the motives for forming these ventures, human resource practices and termination rates; and (c) that these variations can partly be explained by the differences in their respective national cultures.     

Guilt, Shame, and Reparative Behavior: The Effect of Psychological Proximity

Research has paid scant attention to reparative behavior to compensate for unintended wrongdoing or to the role of emotions in doing the right thing. We propose a new approach to investigating reparative behavior by looking at moral emotions and psychological proximity. In this study, we compare the effects of moral emotions (guilt and shame) on the level of compensation for financial harm. We also investigate the role of transgressors’ perceived psychological proximity to the victims of wrongdoing. Our hypotheses were tested through a scenario based questionnaire on a sample of 261 participants. Analyses indicate that (1) guilt has a stronger effect on the level of compensation than shame; (2) psychological proximity influences the level of guilt, shame, and compensation; and (3) shame interacts with psychological proximity to predict compensation, whereas guilt mediates the relationship between psychological proximity and compensation.     

Aspects of second‐order analysis of structured inhomogeneous spatio‐temporal point processes

Statistical methodology for spatio‐temporal point processes is in its infancy. We consider second‐order analysis based on pair correlation functions and K‐functions for general inhomogeneous spatio‐temporal point processes and for inhomogeneous spatio‐temporal Cox processes. Assuming spatio‐temporal separability of the intensity function, we clarify different meanings of second‐order spatio‐temporal separability. One is second‐order spatio‐temporal independence and relates to log‐Gaussian Cox processes with an additive covariance structure of the underlying spatio‐temporal Gaussian process. Another concerns shot‐noise Cox processes with a separable spatio‐temporal covariance density. We propose diagnostic procedures for checking hypotheses of second‐order spatio‐temporal separability, which we apply on simulated and real data.     

Behind the veil: an exploratory study of the myths and realities of women in the Iranian workforce

Despite significant advancements, women executives and professionals have continued to complain about the existence of a glass ceiling in the UK, the USA, Canada and other countries that espouse equal employment opportunities. Little is known about the role and plight of women in the workforce in Islamic countries. In general, Western societies perceive the participation of women in the workforce and their upward career mobility as very limited in Islamic societies. This article seeks to address this limitation in the field by unravelling some of the myths and realities pertaining to women in the Iranian labour force. Based on interviews with 12 Iranians, reality checks were performed on five widely held perceptions of the status of women in Iran, including women's participation in the labour force, appointment to managerial/professional positions, representation in higher education, segregation in the workplace, and Islam's attitude towards non‐Muslims. These issues are discussed in the contexts of foreign direct investment in Iran and other Islamic countries. Implications for international human resource management, including the assignment of women expatriates to Iran and other Islamic nations, are also addressed.     

The Effect of Acculturation on Reparative Behavior in Shame and Guilt Cultures

As the number of immigration and their later generations grow in the workforce of more developed Western countries, understanding the processes and consequences of acculturation has gained a new level of importance. An old and re-emerging issue is the morality and reparative behavior in Western versus Eastern cultures, as well as its antecedents and consequences. We examined the effects of acculturation on the perception of psychological proximity, the intensity of moral emotions of shame and guilt, and the degree of compensation to victims of one＇s wrongdoing. Our sample was comprised of a collectivistic group from a shame culture, China, and an acculturated group of Chinese living in a much less collectivistic society of a guilt culture, Canada. Our results indicated that participants＇ perception of psychological proximity to other people and the level of compensation offered to the victims of transgression were significantly different among the two samples. Furthermore, shame and guilt mediated the relationship between perceived psychological proximity and the decision to compensate differently.     

Cauchy cluster process

In this paper we introduce an instance of the well-know Neyman–Scott cluster process model with clusters having a long tail behaviour. In our model the offspring points are distributed around the parent points according to a circular Cauchy distribution. Using a modified Cramér-von Misses test statistic and the simulated pointwise envelopes it is shown that this model fits better than the Thomas process to the frequently analyzed long-leaf pine data-set.
