Based on in‐depth interviews with highly skilled and business Turkish nationals (HSBTN) in Canada and Germany, this study aims to explore why HSBTN decide to move and whether migration policy differences among the countries of destination affect recent migration motivations of HSBTN. It mainly focuses on the reasons and rationale of HSBTN and their explanations. This study argues that the high skilled and business migrants in general and HSBTN in particular move internationally as a consequence of individual‐level gain beyond economic prospects. 相似文献

The growth of industrial maize farming in Turkey during the first decade of this century points to the primacy of economic development over ecological concerns at a time when global nitrogen and phosphorus flows already exceeded safe limits. In this article we focus on the relations of production as the driver of an economic sector that not only has ecological but also social costs. Through a trend analysis of maize yields as our ecological indicator, we explain how relations of production influence industrial maize farming in this period and how different modes of production (e.g., simple‐commodity producers) participate in a corporate market. A “treadmill of production” perspective argues that simple commodity producers are excluded from industrial treadmills. Our findings indicate that provinces with predominantly simple commodity production experienced significant increases in maize yields and adapted to the industrial maize treadmill. However, there is a significant difference between simple‐commodity producers and large farms that widens over the decade. Our results suggest that simple‐commodity producers are included in ecologically harmful economic practices with significant obstacles. We call for a revision of the assumed relationship between the size of economic operations and their ecological impacts in the critical sociology literature and policy approaches. 相似文献

A two-stage sequential choice model is studied, the first stage being defined by q-Pareto multicriterial choice rule, and
the second stage being defined by scalar extremization model. In this model, at the first stage the q-Pareto rule choses alternatives
which are not only undominated in terms of Pareto comparison, but also includes into choice the alternatives which are dominated
by no more than q alternatives. Since the choice set of the first-stage usually contains too many elements, obtained set is used as a presentation
for the second stage constructed by a scalar extremization model. The properties of the model are studied as well as its representability
to one-stage scalar extremization model. 相似文献

Linear regression models are useful statistical tools to analyze data sets in different fields. There are several methods to estimate the parameters of a linear regression model. These methods usually perform under normally distributed and uncorrelated errors. If error terms are correlated the Conditional Maximum Likelihood (CML) estimation method under normality assumption is often used to estimate the parameters of interest. The CML estimation method is required a distributional assumption on error terms. However, in practice, such distributional assumptions on error terms may not be plausible. In this paper, we propose to estimate the parameters of a linear regression model with autoregressive error term using Empirical Likelihood (EL) method, which is a distribution free estimation method. A small simulation study is provided to evaluate the performance of the proposed estimation method over the CML method. The results of the simulation study show that the proposed estimators based on EL method are remarkably better than the estimators obtained from CML method in terms of mean squared errors (MSE) and bias in almost all the simulation configurations. These findings are also confirmed by the results of the numerical and real data examples. 相似文献

In this study, as alternatives to the maximum likelihood (ML) and the frequency estimators, we propose robust estimators for the parameters of Zipf and Marshall–Olkin Zipf distributions. A small simulation study is given to illustrate the performance of the proposed estimators. We apply the proposed estimators to a real data set from cancer research to illustrate the performance of the proposed estimators over the ML, moments and frequency estimators. We observe that the robust estimators have superiority over the frequency estimators based on classical sample mean. 相似文献

After the implementation of economic restructuring policies in Turkish agriculture, farming communities experienced significant changes in the patterns of agricultural production over the last decade. The dramatic shift from labor‐intensive field crops to maize farming represents such a change, particularly for small‐scale farmers, since high‐yield maize farming is driven by private agrifood corporate demand. In this article, I explore how this shift influences the relations of production in agriculture through a commodity‐system analysis of the maize sector in Turkey. Through the qualitative analysis of the semistructured in‐depth interviews and secondary data, I find that small‐scale farmers are able to participate in maize farming, even as their dependence on production credits to participate in industrial maize farming crucially reduces their bargaining power with private industry. I argue that the traditional Marxist approach, accumulation by dispossession, is not sufficient to explain the participation of small‐scale farmers. Instead, I propose a new concept, entrepreneurial exploitation, to describe the participation of small‐scale investors in the post‐Fordist regime. Thereby, I point to the important role of expansion of credit markets as a consequence of financialization. 相似文献

The Relationship between Marcellus Shale Gas Development in Pennsylvania and Local Perceptions of Risk and Opportunity 总被引:1,自引:0,他引:1
Recent advances in gas and oil drilling technology have led to dramatic boomtown development in many rural areas that have endured extended periods of economic decline. In Pennsylvania's Marcellus gas fields, the recent development of unconventional shale gas resources has not been without controversy. It has been variously framed as a major opportunity for economic revitalization at the local and regional levels and energy independence at the national level, but also as a significant environmental risk, with uncertain and uneven economic benefits. We use data from a survey conducted in 309 school districts located within Pennsylvania's Marcellus Shale region to study the ways local stakeholders perceive both risk and opportunity associated with gas extraction from Marcellus Shale. Our analyses indicate that there is a strong positive association between perceptions of risk and opportunity associated with gas extraction. Further, the intensity of perception of both risk and opportunity is directly associated with the amount of local drilling, suggesting the complexity of local contexts within which local stakeholders evaluate rapid boomtown‐associated community change. In total, these findings complicate the framing of unconventional gas extraction in the Marcellus Shale region, and indeed boomtown growth overall, as fundamentally polarizing issues. 相似文献
