Embedded performers: The relational foundations of record production

This article discusses some network mechanisms that may facilitate involvement in artistic production. More specifically, it explores the nature of the collaborative networks in which musicians are embedded, and looks for the structural configurations that are most conducive to individual creativity. Drawing upon a dataset consisting of 253 music teachers in the Italian region of Trentino, and focusing in particular on record production, the article shows productivity and artistic vitality to be highest among musicians with a balanced combination of ties to other musicians in the local music schools system, and ties to musicians with different territorial locations. These findings contribute to established lines of research on the network determinants of individual productivity and creativity in various domains.     

Power indices and minimal winning coalitions

The Penrose–Banzhaf index and the Shapley–Shubik index are the best-known and the most used tools to measure political power of voters in simple voting games. Most methods to calculate these power indices are based on counting winning coalitions, in particular those coalitions a voter is decisive for. We present a new combinatorial formula how to calculate both indices solely using the set of minimal winning coalitions.     

Minimal winning coalitions in weighted-majority voting games

Riker's size principle for n-person zero-sum games predicts that winning coalitions that form will be minimal in that any player's defection will negate the coalition's winning status. Brams and Fishburn (1995) applied Riker's principle to weighted-majority voting games in which players have voting weights w ₁≥w ₂≥...≥w _n,and a coalition is winning if its members' weights sum to more than half the total weight. We showed that players' bargaining power tends to decrease as their weights decrease when minimal winning coalitions obtain, but that the opposite trend occurs when the minimal winning coalitions that form are “weight-minimal”, referred to as least winning coalitions. In such coalitions, large size may be more harmful than helpful. The present paper extends and refines our earlier analysis by providing mathematical foundations for minimal and least winning coalitions, developing new data to examine relationships between voting weight and voting power, and applying more sophisticated measures of power to these data. We identify all sets of minimal and least winning coalitions that arise from different voting weights for n≤6 and characterize all coalitions that are minimal winning and least winning for every n. While our new analysis supports our earlier findings, it also indicates there to be less negative correlation between voting weight and voting power when least winning coalitions form. In this context, players' powers are fairly insensitive to their voting weights, so being large or small is not particularly important for inclusion in a least winning coalition.     

Power indices expressed in terms of minimal winning coalitions

A voting situation is given by a set of voters and the rules of legislation that determine minimal requirements for a group of voters to pass a motion. A priori measures of voting power, such as the Shapley–Shubik index and the Banzhaf value, show the influence of the individual players in a voting situation and are calculated by looking at marginal contributions in a simple game consisting of winning and losing coalitions derived from the legislative rules. We introduce a new way to calculate these measures directly from the set of minimal winning coalitions and derive explicit formulae for the Shapley–Shubik and Banzhaf values. This new approach logically appealing as it writes measures as functions of the rules of the legislation. For certain classes of games that arise naturally in applications the logical shortcut drastically simplifies the numerical calculations to obtain the indices. The technique generalises directly to all semivalues.     

Occupational rhetoric and ideology: A comparison of copy and original music performers

This study focuses on similarities and differences between occupational rhetorics and ideologies of two groups of local level popular musicians, those who compose and perform their own music and those who perform music made commercially successful by other bands/performers. The analysis of in-depth interviews with twenty-five local level musicians demonstrates that the latter have developed an ideology which legitimates definitions of themselves as audience-oriented technicians who view the performance of music as an economic enterprise; musicians who perform original music share an ideology which stresses creativity over economic reward and legitimates a definition of themselves as primarily artists. Both types of musicians and their ideologies are discussed in relation to larger structural forces of the popular entertainment industry.Revised version of a paper presented at the annual meeting of the Popular Culture Association in the South, Knoxville, TN (October, 1988). The author wishes to thank the two anonymous reviewers for helpful suggestions made on an earlier draft. The author also wishes to thank the Faculty Research Committee at Western Kentucky University for their support during the course of this project.     

Growing up is hard to do: Rock and roll performers as cultural heroes

This paper describes the changing nature of the rock and roll artist as a cultural symbol. The first rock stars (e.g., Elvis) were heroes for the young but decidedly antiheroic to adult society. Transitional ones (e.g., Beatles, Bob Dylan) contributed to the commercial viability of rock and more sharply defined their antiheroism in the 1960's. Contemporary artists are drawn from a wider variety of backgrounds (e.g., Tina Turner, Michael Jackson, Bruce Springsteen) and their cultural significance extends beyond their musical talents. The Live Aid, USA for Africa, and Farm Aid efforts illustrate the latter point. The contemporary heroic status of rock stars is due to two factors: 1) Over the years rock and roll has gradually become pop music; and 2) The antiheroic protests that rock was originally identified with have become more acceptable, even institutionalized. Rock stars are a kind of “new” hero. Their link to the mass media ensures visibility and discloses their antiheroism as well. In a complex process of social typing (also involving media and various audiences), they may reinforce cultural dreams and values, suggest deviant modes of expression, or aid in the development of new cultural forms.     

On the structure of minimal winning coalitions in simple voting games

According to Coleman’s index of collective power, a decision rule that generates a larger number of winning coalitions imparts the collectivity a higher a priori power to act. By the virtue of the monotonicity conditions, a decision rule is totally characterized by the set of minimal winning coalitions. In this paper, we investigate the structure of the families of minimal winning coalitions corresponding to maximal and proper simple voting games (SVG). We show that if the proper and maximal SVG is swap robust and all the minimal winning coalitions are of the same size, then the SVG is a specific (up to an isomorphism) system. We also provide examples of proper SVGs to show that the number of winning coalitions is not monotone with respect to the intuitively appealing system parameters like the number of blockers, number of non-dummies or the size of the minimal blocking set.     

Minimum winning versus oversized coalitions in public finance: the role of uncertainty

This paper extends Persson et al.’s (J Polit Econ 108:1121–1161, 2000) simple legislature in the context of public finance with certainty to uncertainty. In our uncertain world, oversized coalitions (OSCs) as well as minimum winning coalitions (MWCs) may arise in equilibrium, and the agenda setter’s proposed policy may fail to receive a majority support. This is in marked contrast to the certain world, in which only MWCs can arise in equilibrium and the agenda setter’s proposal never fails to pass. When OSCs arise, we show that both public good provision and redistribution are likely to achieve their first-best solution, even if the legislature is simple.     

胜兵先胜而后求战——企业战略竞争的最高法则

《孙子兵法》中有条战略原则是“胜兵先胜而后求战”,意思是打胜仗的军队总是先有了胜利的把握才寻求战机同敌人交战。战前要有准备,要创造必胜的各种条件,清除影响胜利的各种风险,造成未战先胜的局面,然后再战,则战无不胜。这一战略原则,高屋建瓴,也可作为企业战略竞争的最高指导原则。企业制度的战略改革为了适应市场经济发展的需要,为了实现企业战略目标,企业必须进行制度的改革和创新。现代企业制度应能够迅速应对瞬息万变的市场环境,就像军队制度是为了适应战争需要而建立的一样。孙子兵法《九地篇》指出:“善用兵者,譬如率然。率然者,…     

Benchmarking to the world's best in mathematics. Quality control in curriculum and instruction among the top performers in the TIMSS

This article describes the education quality control systems (for mathematics) used by those countries that performed best on the Third International Mathematics and Science Study (TIMSS). Enforced quality control measures are defined as "decision points"--where adherence to the curriculum and instruction system can be reinforced. Most decision points involve stakes for the student, teacher, or school. They involve potential consequences for failure to adhere to the system and to follow the program at a reasonable pace. Generally, countries with more decision points perform better on the TIMSS. When the number of decision points and TIMSS test scores are adjusted for country wealth, the relationship between the degree of (enforced) quality control and student achievement appears to be positive and exponential. CONCLUSION: The more (enforced) quality control measures employed in an education system, the greater is students' academic achievement.     

Allocation of resources in asymmetric competitions: How do the weak maintain a chance of winning?

To maintain a chance of occasionally beating a stronger player in a competition waged over several fields, a weaker player should give up on some of the fields and concentrate resources on the remaining ones. But when do weak players actually do this? And which fields do they give up when the fields differ in their likelihood of being assessed? We report an experimental study of resource allocation in which asymmetric pairs of players compete over asymmetric fields. Symmetric players and symmetric fields are used for control. We find that players behave as follows: (1) Average wins are the same in the symmetric and asymmetric fields conditions and correspond to relative player strength. (2) The proportion of fields given up on decreases with a player’s greater relative strength, increases for asymmetric field likelihoods, and increases when competitions are framed in meaningful context; this proportion is related to wins. (3) When field likelihoods are asymmetric, players’ resource allocation is correlated with likelihood. Wins generally increase with that correlation but the relation is different for players of different strength. (4) The proportion of fields given up on and the correlation with likelihood change with experience towards the values corresponding to higher wins.     

When winning is the only thing: pure strategy Nash equilibria in a three-candidate spatial voting model

It is well known that there are no pure strategy Nash equilibria (PSNE) in the standard three-candidate spatial voting model when candidates maximize their share of the vote. When all that matters to the candidates is winning the election, however, we show that PSNE do exist. We provide a complete characterization of such equilibria and then extend our results to elections with an arbitrary number of candidates.     

The Human‐Environment Dialog in Award‐winning Children’s Picture Books*

Picture books often play an important role in childhood socialization. Given the seriousness of environmental problems, we ask how natural, modified, and built environments have been portrayed in children’s books. To answer this question, we analyze the 296 books receiving Caldecott awards from 1938 to 2008. Two possibilities are explored with respect to content change. Growing concern about critical environmental problems, such as decline in biodiversity and deforestation, may have led to an increase in illustrations and stories about wild animals and the natural environment. Alternatively, the increasing isolation of people from the natural world may have resulted in a decline in the perceived relevance of these environmental issues and resulted in fewer stories and depictions. Our findings support the isolation hypothesis. There have been significant declines in depictions of natural environments and animals while built environments have become much more common. These findings suggest that today’s generation of children are not being socialized, at least through this source, toward an understanding and appreciation of the natural world and the place of humans within it.     

A group, a network and the winning of church union in Canada: a case study in leadership

Au cours du premier quart du xxe siècle, un mouvement oecuménique au sein des Eglises protestantes canadiennes a menéà leur fusion, et à la création de ľEglise Unie du Canada. Au moyen de documents ďarchives, j'étudie dans cet article le leadership du mouvement social qui a produit cette fusion. J'analyse ďabord comment la structure du leadership a évolué, du groupe fondateur à un réseau étendu et de faible densité. Les actions du leadership à divers niveaux de ľEglise et de la société sont ensuite examinées, ainsi que les activités dissidentes de plusieurs membres du groupe fondateur.
This paper, based on archival data, is a study of pro-change leadership in a social movement: namely, the ecumenical movement within the Canadian Protestant churches during the first quarter of this century which succeeded in merging several denominations into the United Church of Canada. First, the structure of the leadership is traced from a founding group to a dispersed and enlarged network, then the leadership is displayed in action at various levels of the church and society. Finally, the dissident activity of several of the original group members is investigated.
