This paper's focus is on the knowledge management challenges that come along with technology-based new business development (NBD). NBD thrives upon the exploration of knowledge, under radical uncertainty. Furthermore, existing knowledge may both enable and constrain the radical innovation process. These characteristics make the dominant approach of knowledge management – focusing on codifying, collecting and distributing knowledge – unsuited for NBD. We suggest that knowledge management can enhance NBD by focusing on experimenting, monitoring and integrating knowledge. This is illustrated by case study observations of radical innovation processes. 相似文献

This paper investigates the number of profiles at which a social choice function is manipulable. It is found that there is
a lower bound on this number when the social choice function is assumed non-dictatorial. Also, any number between this lower
bound and the maximal number of profiles may be obtained as the number of manipulable profiles of some social choice function.

This paper analyzes income-pooling by using a unique Danish data set that includes questions on income pooling among 1,696
couples. The analyses show that most Danish households use some kind of income pooling and that the proportion of income pooled
varies considerably according to individual characteristics (age, education, occupation, past partners, upbringing) and household
characteristics (household income, duration of marriage, location of residence and the existence of public goods, including
children). However, when all variables are evaluated in a common model, the duration of marriage and the existence of children
predominantly affect the likelihood of income pooling.

Two aspects of research on racism in Flanders (Belgium) are discussed in this article based on results from large-scale surveys between 1991 and 2003. The first relates to the (negative) attitudes of the majority toward foreigners (everyday racism) . The second relates to the vote for an extreme right-wing political party that emphasizes anti-immigrant viewpoints in its political program and propaganda (political racism) . Our main research question is how both forms of racism are related. First, theories to explain political racism are reviewed. Some theories suggest an extreme right-wing vote to be motivated by a content-related agreement with (part of) the program of these parties (e.g., racism, nationalism, or authoritarianism). Other theories suggest that this vote represents an antipolitical protest vote. From these theories, hypotheses are derived regarding the background characteristics and attitudes that are associated with an extreme right-wing vote (e.g., the Vlaams Blok). These hypotheses are tested using data from election research in 1991, 1999, and 2003. The results suggest that the vote for the party Vlaams Blok is a rational vote. Of all theories, the theory suggesting that everyday racism plays a prominent role received most support. Everyday racism thus motivates political racism in the Flemish part of Belgium. 相似文献

This paper develops a model of political consensus in order to explain the missing link between inequality and political redistribution.
Political consensus is an implicit agreement not to vote for extreme policy proposals. We show that such an agreement may
play an efficiency-enhancing role. Voters anticipate that voting for extremist parties increases policy uncertainty in the
future. A political consensus among voters reduces policy uncertainty because self-interested politicians propose non-discriminatory
policies. We study how much inequality can be sustained in a democracy and how the limits to redistribution vary with initial
inequality. The bounds of the set of political equilibria may react in a fundamentally different manner to changes in exogenous
variables than do the policy variables in the one-dimensional, one-shot game. More initial inequality need not lead to more
redistribution from the rich to the poor. The maximum amount of redistribution decreases with inequality if (and only if)
agents are sufficiently patient. In this case inequality is politically self-sustaining. 相似文献

Maternal Sensitivity Moderates the Relation between Negative Discipline and Aggression in Early Childhood 总被引:1,自引:0,他引:1
Lenneke R. A. Alink Judi Mesman Jantien van Zeijl Mirjam N. Stolk Femmie Juffer Marian J. Bakermans-Kranenburg Marinus H. van IJzendoorn Hans M. Koot 《Social Development》2009,18(1):99-120
Three models regarding the relation between maternal (in)sensitivity, negative discipline, and child aggression were examined in a sample of 117 mother–child pairs with high scores on child externalizing behavior: (1) Sensitivity and discipline are uniquely related to child aggression (the additive model); (2) the relation between discipline and aggression is moderated by maternal sensitivity (the moderating model); (3) the relation between sensitivity and aggression is mediated by maternal discipline (the mediating model). Parenting and child aggression were observed when the children were on average 26.71 months old (range of 13.58 to 41.91 months) and again one year later. Results supported the moderating model. More negative discipline was related to more child aggression one year later, but only when mothers were insensitive. This finding supports the idea that the affective context is important for the impact of negative discipline on child development. 相似文献

This article reports on qualitative research among 48 social professionals, managers and policymakers and their perceptions of activating citizenship, social work roles and responsibilities, carried out in Utrecht and Tartu. Professionals from both countries agreed to the idea of activating citizenship but stressing the perspective of personalised or lived citizenship, each person to his own capacities and embedded in the personal context. Nearly all respondents were critical about the recognition of social workers as a full profession, about the new management way of steering social work and about cooperation between different groups of professionals and services. Although both countries have quite different historical and cultural backgrounds, the authors found many similarities among social workers regarding their ideas on support, participation and commitment to the people they work for and work with. International research projects contribute to a more strongly recognised social work theory and social work practice by getting a better understanding, in particular of the way social work adapts to different contexts but from a highly recognisable international discourse within social work. 相似文献

The literature suggests that in Italy husbands contribute less to unpaid household work than in any other European country,
while women have the lowest market employment rates. Here we examine the time allocation of Italian couples on which there
are surprisingly few studies to date. We analyze simultaneously the time allocated by husband and wife to market work, childcare
and housework, allowing for various interactions. We use data drawn from the Italian national Time Use Survey 2002–2003 for
the analysis. We find that spousal time allocation is sensitive to personal and household characteristics, such as, in particular,
education and children’s age. Evidence shows that men married to more highly educated women spend more time with their children.
The husband’s own characteristics have less of an effect on women’s time allocation. We also find that patterns differ substantially
between weekends and weekdays. The estimated correlations between the unobservable factors affecting the couple’s time allocation
suggest that the time devoted by parents to childcare is complementary and that the time they devote to housework is substitutable
across weekends and other weekdays. 相似文献
