Psychological taxing in Flemish municipalities

We analyse whether the psychological pricing in the private sector has a public sector counterpart in tax policy. Analysing the main theoretical arguments for the existence of price points, and applying them to the public sector, suggests that psychological taxing reveals itself by the use of non-0 ending tax rates. The tax rate endings of the local income taxes, which are set by 308 Flemish municipalities in the fiscal year 1998, suggests the presence of psychological taxing. Non-0 endings occur more frequently in municipalities where demand for public policy is more elastic (and where, therefore, the benefits to the politicians from setting a tax just below a tax point is higher). The pre-tax income inequality and the level of the tax rate positively affect psychological taxing. The latter effect is reinforced in those municipalities where the existing tax rate is above the average tax rate in neighbouring municipalities and below their neighbours’ minimum, although this effect has a limited effect and is offset the further below the minimum the tax is set.     

Knowledge sharing for innovation performance improvement in micro/SMEs: an insight from the creative sector

Abstract

As economies become more reliant on innovative, knowledge-intensive firms, understanding the interaction between knowledge and improving innovation performance is increasingly important. Although most UK businesses are micro, small or medium-sized enterprises (micro/SMEs), knowledge management research has tended to focus on large companies Knowledge sharing can be critical for innovation performance, especially for smaller players with limited resources. Our study presents an insight from micro/SMEs operating in the highly knowledge-intensive and innovative games/entertainment software development sector. Using a mixed method approach, we investigate knowledge sharing and its contribution to firm innovation performance improvements. Our findings suggest that micro/SMEs are at the forefront of the creative sector precisely because of their smaller size. Our study reveals evidence of knowledge donation but limited evidence of knowledge collection in the knowledge sharing process. We develop a model highlighting the importance of industry context, individual knowledge and organizational size in knowledge sharing for innovation performance.     

The Challenge of Activist Coalition Governance: Accommodating Diversity to Create Institutions—An Approach Via the Inter-Relationships Between Action,Project and Instrument

This paper addresses the governance of hybrid forms of organisation arising in new social movements, characterised by diverse institutional logics and democratic decision making. Our theoretical framework encompasses the governance theory of Kooiman with insights from new developments in institutional theory. This framework allows us to examine governance as the capacity to link together disparate institutions from the perspective of interactions between action, project and instrument, and to explore the institutional work that results from these interactions. By studying a French activist coalition, we explore the micro-processes that make it possible to accommodate diversity in an organisation intended to produce solid institutions. Our results show that the three elements of governance—action, project and instrument—have an impact on the cohesion of diversity-based organisations and on building and consolidating institutions. When these elements are flexible and versatile enough, and when they mutually nurture each other, a plurality of logics is possible, the coalition goes forward, and true institutional work can be accomplished. When one of these elements of governance—instruments in particular—becomes autonomous and rigid, diversity is more difficult to achieve and one logic is likely to prevail over the others, compromising the very survival of the coalition and impeding the emergence of a new institution.     

Contributions of participatory ergonomics to the improvement of safety culture in an industrial context

This paper presents the results of an ergonomic intervention conducted within a blast furnace plant. As part of its risk prevention program, the company decided to set up an action plan, in a participatory manner, by setting up working groups to solve health & safety issues. This field mission involved 230 employees, 80 of whom participated actively by being incorporated into working groups. After four months of intervention, a questionnaire survey has been conducted among employees to study the effects of participation on the safety climate. The results seem promising and show that the benefits of participation are numerous: a more positive safety climate associated to safer attitudes and behaviors. However, rather than just participation, it seems to be the employee involvement in the working groups and the satisfaction they derive from their participation that guarantee these positive results. Hence, participatory ergonomics seems to be an effective way to decrease the number of unsafe behaviors at work, provided that the type of participation has been previously well defined and organized according to the specific context of each organization.     

The New Chinese Migrants in France

Like the United Kingdom and the Netherlands, France is one of the major centres of Chinese migration in Europe. Chinese sojourners arrived in France at the beginning of the twentieth century and the 1911 census showed the presence of 238 Chinese in the country. From 1900 to World War I, this little community remained heterogeneous in its socio‐economic and professional composition (Archaimbault, 1952). Changes in this community occurred during World War I when the lack of labourers led the French Government to recruit 140,000 Chinese workers (Wou, 1939). The 2,000 to 4,000 Chinese who remained in France after the war constituted the basis of a Chinese community in France. In the 1920s, they were joined by some 2,000 student labourers (Wang, 2001; Bailey, 1988). From the 1920s to the 1940s, Zhejiang immigration in France rose until World War II and the rise of the communist party in China stopped the movement. Yet, Chinese immigration did not cease. Migrants of Chinese origin arrived essentially from the old French Indochina (Viet Nam‐Laos‐Cambodia) (Le, 1995). Immigration from these countries increased in the 1970s when different conflicts occurred. From the late 1970s to the early 1980s, France also saw the arrival, albeit in smaller numbers, of Chinese from Hong Kong and Taiwan, family members of citizens of the People's Republic of China (PRC). The new wave of Chinese migration from PRC started in the mid‐1980s and grew steadily until now, with some peaks, e.g. in the mid‐1990s. Recent fieldwork in France approached this community, in particular, those living in France with a precarious administrative status (asylum seekers or clandestine migrants). In general, the situation of the population covered by this fieldwork was still precarious. Although the paper does not include other categories such as students, entrepreneurs, or researchers, it is nevertheless possible to gather some details on the basis of French official data and reports. The following sections deal with the growing Chinese presence in France, and their precarious status. Most recent research tends to show a diversified Chinese migrant population profile; it also shows that they are still primarily active in the French ethnic Chinese market. In the initial stages of migration, the Chinese migrants continue to maintain links with China and sometimes with Chinese communities in Europe.     

Zero-spiked regression models generated by gamma random variables with application in the resin oil production

Zero-inflated data are more frequent when the data represent counts. However, there are practical situations in which continuous data contain an excess of zeros. In these cases, the zero-inflated Poisson, binomial or negative binomial models are not suitable. In order to reduce this gap, we propose the zero-spiked gamma-Weibull (ZSGW) model by mixing a distribution which is degenerate at zero with the gamma-Weibull distribution, which has positive support. The model attempts to estimate simultaneously the effects of explanatory variables on the response variable and the zero-spiked. We consider a frequentist analysis and a non-parametric bootstrap for estimating the parameters of the ZSGW regression model. We derive the appropriate matrices for assessing local influence on the model parameters. We illustrate the performance of the proposed regression model by means of a real data set (copaiba oil resin production) from a study carried out at the Department of Forest Science of the Luiz de Queiroz School of Agriculture, University of São Paulo. Based on the ZSGW regression model, we determine the explanatory variables that can influence the excess of zeros of the resin oil production and identify influential observations. We also prove empirically that the proposed regression model can be superior to the zero-adjusted inverse Gaussian regression model to fit zero-inflated positive continuous data.     

Quasi- and pseudo-maximum likelihood estimators for discretely observed continuous-time Markov branching processes

This article deals with quasi- and pseudo-likelihood estimation for a class of continuous-time multi-type Markov branching processes observed at discrete points in time. “Conventional” and conditional estimation are discussed for both approaches. We compare their properties and identify situations where they lead to asymptotically equivalent estimators. Both approaches possess robustness properties, and coincide with maximum likelihood estimation in some cases. Quasi-likelihood functions involving only linear combinations of the data may be unable to estimate all model parameters. Remedial measures exist, including the resort either to non-linear functions of the data or to conditioning the moments on appropriate sigma-algebras. The method of pseudo-likelihood may also resolve this issue. We investigate the properties of these approaches in three examples: the pure birth process, the linear birth-and-death process, and a two-type process that generalizes the previous two examples. Simulations studies are conducted to evaluate performance in finite samples.
