When Do Expert Teams Fail to Create Impactful Inventions?

We investigate the salience of expertise in creating high impact inventions and question experts’ ability to deploy novel ideas. Specifically, we examine the relationships between expertise, component originality, and a team's structural holes’ position in the collaborative network and propose that, in relative terms, expert teams create lower impact inventions if they deploy more original components and if they occupy structural holes. We test and confirm our hypotheses in a sample of semiconductor firms. In post‐hoc analyses, we find a three‐way interaction where the negative effect of structural holes almost disappears when an expert team experiments with original components whereas an increase in non‐redundancy is detrimental when teams with high expertise use familiar components. Our findings inform a foundational view of the invention process and provide novel insights into the contingent benefits of domain expertise.     

The fraying modern map: Failed states and contraband capitalism

Inter‐relationships between markets and states are re‐making the world political map but in some instances these interactions have created zones of political conflict where the world political map is fraying and coming undone. In certain ‘wild zones’ of the world, state failure and illegal exchange are the prevalent processes conditioning civil and nationalist wars. This paper considers the general relationships between turbo‐globalisation, contraband capitalism, and failed states. Using the case of Russia and Chechnya, it seeks to illustrate and describe the illegal and illicit forms of governance that are fraying the ‘modern map’ and contributing to the complexity of the story of ‘nationalism in a globalising world.’     

Segmented trend modelling of the US GNP series

Structural changes in economic time series are modelled as piecewise linear trends. A statistical method is considered to estimate and select the number and location of trend-breakks simultaneously. The method is applied to the GNP series of the US.     

A strategic implementation of the Average Tree solution for cycle-free graph games

In this note we provide a strategic implementation of the Average Tree solution for zero-monotonic cycle-free graph games. That is, we propose a non-cooperative mechanism of which the unique subgame perfect equilibrium payoffs correspond to the average hierarchical outcome of the game. This mechanism takes into account that a player is only able to communicate with other players (i.e., to make proposals about a division of the surplus of cooperation) when they are connected in the graph.     

Depoliticisation,the Management of Money and the Renewal of Social Democracy: New Labour's Keynesianism and the Political Economy of ‘Discretionary Constraint’

Pointing to its radical underpinnings in so-called ‘Open Marxism’ and its theory of the state (one that subsumes the state in the capital relation), this article critically scrutinises Peter Burnham's thesis of ‘depoliticisation’ as a dominant accumulation strategy and regime. The article identifies ambiguities around Burnham's depiction of New Labour in power as committed to depoliticisation. It addresses these by drawing a distinction between regime of accumulation and mode of regulation, characterising New Labour's political economy in terms of the latter as a form of depoliticised Keynesianism framed by ‘discretionary constraint’. Contra-Burnham, the article points to the continued efficacy of Keynesian and social democratic political agency in the context of a dialectic of depoliticisation and repoliticisation focused on the role and power of the state. This dialectic is symptomatic of the contested regulation of capitalism around the defence of the value of money, on the one hand, and its broader management and redistribution, on the other.     

IPv6的地址结构特点与管理机制分析

本文主要介绍了有关IPv6互联网的网络地址结构及其管理机制。与现行的IPv4地址相比，IPv6在地址的长度、分类方法、表示方法和类型等方面均不同相同。它可有效地解决IP地址枯竭与路由效率低下的问题，同时具有地址聚类性、多播性、任播性和接口多址性等特点；而在IPv6地址管理方面则采用层次化路由选择策略，支持QoS路由协议，将地址解析通过领导发现协议来实现，新增了无态地址的自动配置，使得网络地址的重新编号变得更加简单快速。最后通过模拟仿真的方法，进一步分析说明了IPv6网络的性能。     

Understanding the Role of Identity in the Constraint Negotiation Process

Sociological theory related to identity was adapted to explore the influence of identity on respondents’ perceived leisure constraints and constraint negotiation. We hypothesized that perceived constraints to recreational golf and efforts to negotiate constraints would be predicted by the degree to which respondents embraced their leisure-related identity of “golfer.” It was also hypothesized that the perception of constraints and constraint negotiation would depend upon the degree to which respondents perceive that the identities they embrace facilitate or conflict. Findings showed support for the hypothesized model.     

Place Meanings Ascribed to Marine Settings: The Case of the Great Barrier Reef Marine Park

Using data collected from in-depth interviews of recreational visitors to Australia's Great Barrier Reef Marine Park, place-related meanings ascribed to a marine environment are described. The usefulness of using symbolic interactionism to understand the creation of these meanings is also assessed. Ten meaning-themes emerged (aesthetic beauty, lack of built infrastructure/pristine environment, abundance and diversity of coral and other wildlife, unique natural resource, facilitation of desired recreation activity, safety and accessibility, curiosity and exploration, sense of connection to the natural world, escape from the everyday, and experiences with family and friends), and evidence supporting the utility of symbolic interactionism was identified. Using these findings, researchers may be better able to identify place meanings and the processes that create them.
