Conditioning as disintegration

Conditional probability distributions seem to have a bad reputation when it comes to rigorous treatment of conditioning. Technical arguments are published as manipulations of Radon–Nikodym derivatives, although we all secretly perform heuristic calculations using elementary definitions of conditional probabilities. In print, measurability and averaging properties substitute for intuitive ideas about random variables behaving like constants given particular conditioning information.
One way to engage in rigorous, guilt-free manipulation of conditional distributions is to treat them as disintegrating measures—families of probability measures concentrating on the level sets of a conditioning statistic. In this paper we present a little theory and a range of examples—from EM algorithms and the Neyman factorization, through Bayes theory and marginalization paradoxes—to suggest that disintegrations have both intuitive appeal and the rigor needed for many problems in mathematical statistics.     

Managing five paradoxes of knowledge exchange in networked organizations: new priorities for HRM?

The life‐blood of most organizations is knowledge. Too often, the very mechanisms set up to facilitate knowledge flow militate against it. This is because they are instituted in a top‐down way, they are cumbersome to manage and the bridges of trust fail to get built. In their thirst for innovation, the tendency is for firms to set up elaborate transmission channels and governance systems. As a result, staff are drowned in a deluge of mundane intranet messages and bewildered by matrix structures, while off‐the‐wall ideas and mould‐breaking insights are routinely missed. Added to this is the challenge of operating across professional, cultural, regional and linguistic boundaries, where ways of sharing knowledge differ markedly, even within the same project team. Drawing upon extensive research with scientists in the ATLAS collaboration (a high‐energy particle physics experiment comprising 3,500 scientists from 38 countries), we explore five paradoxes associated with knowledge exchange in global networks. Each paradox leads to a proposition which takes the theory and practice of knowledge management in a fresh direction. We conclude by outlining a number of HRM priorities for international knowledge‐intensive organizations.     

Wine Tourism as an Opportunity for Tourism Development: Examples of Good Practice in Slovenia

The authors discuss wine tourism activities in the context of general tourism development in Slovenia. The country’s winegrowing areas have developed traditionally important viticulture, a relatively intensive production of typical grape varieties and in some cases also a distinct entrepreneurial spirit, which consequently reflects in tourism and regional development, based on diverse cultural heritage and natural values. Three Slovene wine regions are divided into nine wine districts with their own identities and more or less distinct terroirs. Despite a several centuries’ long tradition and a rich wine culture, it is evident that in national tourism strategies and development plans, wine tourism still does not occupy the position that it probably deserves, although most of the documents stress its potential for local or regional development. On the other hand, the authors recognize a significant interest among winemakers and tourism professionals for strategic cooperation and systematic approach to develop wine tourism in the selected destinations. The authors therefore focus on some paradoxes and emphasize examples of good practice at the national, regional, and local levels.

A framework for the analysis of global, regional and local business networks

In this article we are dealing with the global, regional and local questions of the business. We raise the following question: is there a relation between network management (networking) and the spatial type of the network. We make a cross analysis of networking and spatial types of the network. The paper builds on the model of networking (Ford et al., 2002; Ford et al., 2003; Håkansson et al., 2009), the network paradoxes (Håkansson and Ford, 2002) and the model of 6 Cs (Ritter & Ford, 2006). We emphasize the strategic importance of the interpretation of network pictures. In order to answer the research question we create a theoretical conceptual frame called the Spatial Networking Matrix. We use the method of explorative expert interview in order to introduce some experiences of company leaders and managers concerning networking and spatiality. We conclude that after further development, the Spatial Networking Matrix can help to analyze networking and spatial types of networks at once, deepen the understanding of the real business world and through all of these, be a useful tool for business practice.     

Telework paradoxes and practices: the importance of the nature of work

Research on telework often focuses on the outcomes of telework, investigating if telework is ultimately a ‘good’ or a ‘bad’ thing for teleworkers and their organisations. However, findings across telework research studies are often inconclusive, requiring deeper engagement with potential explanations for contradictory and paradoxical results. This study uses virtual ethnography (netnography) to investigate naturally occurring data. By analysing online debates related to Yahoo!'s decision to ban telework for its employees, this study surfaces aspects currently overlooked by telework research. These findings suggest that the diversity of the nature of work undertaken by knowledge workers and perceived differences in the suitability of different tasks for telework are of critical importance for understanding telework from a practice perspective. However, deeper engagement with the different kinds of work activities of knowledge workers is currently missing in the telework research literature. This study therefore contributes to better understanding of telework and paradoxical findings in telework research.     

Utility of gambling II: risk,paradoxes, and data

We specialize our results on entropy-modified representations of event-based gambles to representations of probability-based gambles by assuming an implicit event structure underlying the probabilities, and adding assumptions linking the qualitative properties of the former and the latter. Under segregation and under duplex decomposition, we obtain numerical representations consisting of a linear weighted utility term plus a term corresponding to information-theoretical entropies. These representations accommodate the Allais paradox and most of the data due to Birnbaum and associates. A representation of mixed event-and probability-based gambles accommodates the Ellsberg paradox. We suggest possible extensions to handle the data not accommodated.      

Unsettling aspects of voting theory

Summary. Voting procedures are known to be plagued with a variety of difficulties such as strategic voting, or where a voter is rewarded with a better election outcome by not voting, or where a winning candidate can lose by receiving more support. Once we know that these problems can occur, the next objective should be to completely understand how, why, and where they arise. Namely, for each election procedure, the new goal is to determine when such problems can occur, all voter types who can cause these difficulties, and the actions they must take. This paper develops an easily used approach to handle all of these issues for standard voting methods. New intuitive explanations for these various oddities follow from this approach.

Sustainability and integration – the principal challenges to tourism and tourism research

ABSTRACT

What are the biggest challenges facing tourism and tourism research? This paper answers this question by canvasing the opinions of recognized experts in the field. The analysis is based on 30 interviews with fellows of the International Academy for the Study of Tourism. Two key thematic issues were identified. First, the pragmatic issue of how to operationalize sustainability and its various sub-elements, such as climate change, overtourism, and tourisation to ensure the long-term future of tourism. Second, the need for further integration between disciplines within the tourism field, between tourism and other fields, and between research and practice.     

模块化悖论与模块化战略

模块化不仅是一种创新方法,也是一种战略手段。模块化设计过程是一个包括“决策之决策”、“并行性改进”和“选择之选择”的三个阶段模式,需要相应地支付“沉没成本”、“变动成本”和“周期成本,”并形成了“结构价值”、“试验价值”和“创新价值;”模块化深化完善伴随着三大发展悖论:模块化发展与系统控制悖论、模块化无量纲设计与制造过程模块化悖论以及知识模块化与物理模块化悖论;模块化发展过程孕育着三类战略管理手段:模块化引导战略、模块化控制战略以及模块化匹配战略。模块化贯穿于设计和制造全过程,模块化发展动力根源于设计、制造和消费各自内部以及三者之间战略互动。
