全球化视角下的中国西部文化多样性——基于边疆与中心地位和作用的新认识

在全球化过程中,地区性与国际性同步加强,表现出有的文化体系互相配合,有的甚至发生激烈冲突.全球化不但可能导致文化的同质化(homogeniztion),而且还会伴随有意识形态的趋同,甚至使文化本身更趋多样化(diversification),直至出现对多元取向认同的意识形态趋向;文化交流与文化解构,反映了不同文化圈里的人们如何彼此相互沟通、设置动态平台的必要.其中,文化交流属于文化的横向动态,它关注的是不同的大文化体系之间的关系(inter-cultural relations),文化解构则属于文化的纵向动态,它关注的则是在同一文化体系中的不同地方亚文化之间的关系(intra-cultural relations)①.无论是纵向还是横向,不同文化关系的适当处理,不能脱离通过比较异中之同而所产生的认识,即对于中西文化或其中某种文化体系内的亚文化现象的普遍性、共性(similar feature)的认识;同时也不能脱离通过比较同中之异而所获得的认识,即对于中西文化或其中某种文化体系内的亚文化现象的特殊性、个性(specific feature)的辨别.     

Transform orders and stochastic monotonicity of statistical functionals

In some inferential statistical methods, such as tests and confidence intervals, it is important to describe the stochastic behavior of statistical functionals, aside from their large sample properties. We study such a behavior in terms of the usual stochastic order. For this purpose, we introduce a generalized family of stochastic orders, which is referred to as transform orders, showing that it provides a flexible framework for deriving stochastic monotonicity results. Given that our general definition makes it possible to obtain some well known ordering relations as particular cases, we can easily apply our method to different families of functionals. These include some prominent inequality measures, such as the generalized entropy, the Gini index, and its generalizations. We also illustrate the applicability of our approach by determining the least favorable distribution, and the behavior of some bootstrap statistics, in some goodness-of-fit testing procedures.     

Tasks,occupations and wages in OECD countries

This article investigates the links between earnings, human capital and job tasks, using internationally comparable information from the OECD Survey of Adult Skills. The authors use the theoretical framework developed by Autor and Handel (2013) and extend their empirical results to 21 OECD countries. The data allow for a richer characterization of workers' human capital by including both educational attainment and a measure of cognitive skills. Their findings confirm the predictive power of job tasks in explaining wage differences, both between and within occupations, and provide empirical support for the model's prediction in the vast majority of countries.     

The Determinants of Contract Length in Temporary Help Employment

Abstract. This paper investigates the determinants of labor contract duration in the case of temporary help employment. A simple theoretical model is developed, in order to depict the choice of contract length made by a firm that recruits temporary agency workers to deal with activity peaks. Assuming that the hiring of a new worker is associated with selection and training costs, longer contracts have an option value in face of a greater persistence of positive shocks. The model has two testable implications. First, the degree of serial correlation in market demand positively affects contract length. Second, the shortage of alternative employment opportunities negatively affects contract length. Using data on Italian temporary agency workers, both implications are confirmed by the econometric analysis.     

Accountability as a Managerial Tool in Non-Profit Organizations: Evidence from Italian CSVs

The long-term performance of NPOs is based on their ability to link and maximize social value as defined in their mission. This involves legitimacy obtained from stakeholders influenced by and influencing NPO activities, and their operational capacity or economic efficiency. Thus, NPOs have to utilize multiple level accountability systems which should be compatible with their multiple objectives and stakeholders’ claims. The accountability system of an NPO should focus on its operational capacity, because in order to maximize its efficiency, an NPO has to measure its resource use, cost structure, and financial structure. Legitimacy obtained from stakeholders is also integral. If an organization is considered a social contract between multiple stakeholders, it has to consider the social economic effects of its activities and it has the duty to account for them. However, since the mission of an NPO is to create and distribute social value to a certain specific group, its social value creation has the most important role and an NPO should measure the social value it has created. This article analyzes the accountability system of a specific type of Italian NPO called Centri di Servizio per il Volontariato (CSVs)—namely centers which provide services for voluntary associations. The aim of the research is to verify if the accountability system adopted by CSVs satisfies their need for multiple level information (operational, legitimacy, and social value) and accomplishes their stakeholder claims, and to determine its impact on the definition and implementation of their strategy and on their long-term performance. The research was carried out using the action research model, and the findings are based on the analysis of a sample of 64 CSVs situated throughout Italy.     

UNBUNDLING THE INCUMBENT: EVIDENCE FROM UK BROADBAND

We consider the impact of a regulatory process forcing an incumbent telecom operator to make its local broadband network available to other companies (local loop unbundling, or LLU). Entrants are then able to upgrade their individual lines and offer Internet services directly to customers. Employing a very detailed data set covering the whole of the United Kingdom, we find that, over the course of time, many entrants have begun to take advantage of unbundling. LLU entry only had a positive effect on broadband penetration in the early years, and no longer in the recent years as the market reached maturity. In contrast, LLU entry continues to have a positive impact on the quality of the service provided, as entrants differentiate their products upwards compared to the incumbent. We also assess the impact of competition from an alternative form of technology (cable) which is not subject to regulation, and what we discover is that inter‐platform competition has a positive impact on both penetration and quality.     

Search and Recombination Process to Innovate: A Review of the Empirical Evidence and a Research Agenda

The view of innovation as a process of searching and recombining existing knowledge elements has been adopted in several industries. The innovation management literature has recognized the fundamental role that search and recombination play in innovation development. However, the relevant research has provided complex, fragmented and mixed results. The authors aim to identify areas of convergence and provide directions for future research by collecting empirical evidence regarding how firms conduct the search and recombination process. They conducted a systematic literature review of 87 empirical articles in the innovation management field. The review reveals differences among the solutions adopted both within and across organizational boundaries. Specifically, it shows that the variety and diversity of knowledge elements are critical in creating breakthrough innovations. Therefore, this paper discusses how to provide access to a variety of knowledge elements. It also highlights other fundamental questions calling for further investigation, such as how scientific knowledge elements are successfully recombined and how recombination and search dynamics occur in small and medium‐sized firms. The review concludes by summarizing the current state of affairs and suggests promising directions for future investigation.     

Identifying Demand and Supply of Part‐time Jobs Using Personnel Data. An Application to Italy

The percentage of part‐time workers in Italy is very low compared with most European countries. In this paper we try to contribute to an explanation. We use data on the employees of a large Italian company operating in the service sector, and apply a particular econometric framework that allows identification of potential demand and supply. We find that demand and supply are potentially very large on average, but they are difficult to match at the individual worker/job level. The firm might observe a relevant employee’s characteristics that are positively correlated with the employee’s propensity to a part‐time job but are negatively correlated with the profitability of that employee on that job. The firm might also use the revealed willingness to switch to a part‐time job as a sign that the employee is likely to be unprofitable for the company.     

Who is watching? The market for prostitution services

This paper presents an economic model of prostitution that differs from the existing literature in that it makes no restrictive assumptions regarding the gender, pay, and nature of forgone earning opportunities of prostitutes and clients, and applies the same behavioural hypotheses to both. Our model gives a central role of stigma and reputation effects to both clients and prostitutes. We discuss demand, supply, and equilibrium results, indicating the possible effects of different policies on the industry and its different markets.
