基于主体能动性理论,通过229份有效问卷调查分析,探讨工作连通对工作退缩行为的影响及作用机制。研究发现：工作连通与工作退缩行为、工作连通与角色超载均正相关;角色超载工作连通和工作退缩之间起中介作用;辱虐型领导调节了工作连通和工作退缩行为之间的关系,当辱虐型领导越强,工作连通与工作退缩的正向关系越强。     

Strategies for Introducing Organizational Innovation to Public Service Organizations

As social systems, organizations need to ensure connectivity between established and deviant communication streams to accomplish organizational innovation. This article explores elements and systemic strategies of connectivity formation for the introduction of an organizational innovation such as the concept of crowd innovation in the public sector. For public administrations, crowd innovation represents an organizational innovation since it implies broad participation and the integration of external ideas, and thus often opposes prevalent organizational structures. Our findings contribute to the knowledge on systemic innovation management and suggest that public managers can enhance connectivity formation by addressing semantics, routines, practices, roles, and redundancies.

Impact of urban developments on the functional connectivity of forested habitats: a joint contribution of advanced urban models and landscape graphs

The impacts of urban growth on biodiversity vary according to the form and the intensity of urbanisation. However, there is a lack of knowledge about the consequences of the type of urban structure (e.g. monocentric vs polycentric), the shape of urban boundaries, the local density of residential development, on the habitats of wildlife species. In this context, this paper focuses on the relationship between forms of urbanisation and functional connectivity of ecological habitats. In the urban region of Besançon (eastern France), three emblematic protected species were selected to represent forest mammals. From the initial state describing current land cover, five prospective residential development scenarios were simulated, corresponding to the form currently most commonly found (e.g. compact development, transit-oriented development, polycentric development). For each scenario, we also simulate the volume of traffic on the road network to allow for the barrier effect of roads on habitat connectivity. Then, for each development scenario, we model the functional connectivity of habitats of the various target species using landscape graphs. Results show that compact city maintains more functional connectivity for all the species considered whereas urban sprawl leads to much more marked impacts. Moderately compact and regulated periurban scenarios have intermediate levels of impact. The transit-oriented development scenario produces specific impact values according to the species. An interesting point is that the decline in functional connectivity of forest habitats is more due to increased traffic than residential development proper. This outlines the relevance of integrated models for simulating both land use and transport at a fine scale.     

A comparison of indirect connectivity in Chinese airport hubs: 2010 vs. 2015

Airport hubs’ indirect connectivity is important for any aviation network. Indirect connectivity describes the capacity of airport hubs to provide indirect connections over the airline network. As the Chinese aviation industry has experienced development, this paper offers a comparative analysis of indirect connectivity for Chinese airport hubs between 2010 and 2015. We investigate wave-system structures, weighted indirect connectivity (WIC) and indirect connections of the top ten airport hubs in China. In the spatial analysis, this paper surveys the spatial patterns of indirect connections at four important airport hubs. Beijing-Capital airport has strong indirect connectivity worldwide. Pudong and Hongqiao airports worked together to maximize the spatial coverage of Shanghai. Guangzhou-Baiyun airport has sufficient indirect connections across southern China, and it intends to expand its spatial influence into northern cities.     

Food tourists’ connectivity through the 5A journey and advocacy: comparison between generations Y and X

ABSTRACT

By adopting the new 5A model of Marketing 4.0, which conceptualizes a consumer-driven paradigm shift in digital marketing, this study empirically investigated food tourists’ connectivity throughout the 5A process (aware, appeal, ask, act, and advocate). Furthermore, we compared the 5A journeys of Generation Y and Generation X. Along the 5A path, both generations indicated the strongest social connectivity in the ask stage. Generation Y showed stronger social connectivity than Generation X, while there was no significant difference in channel connectivity. The social connectivity in the advocate stage was most strongly correlated with that in the act stage. Within each generation, active netizens were more strongly engaged in sharing and positive/negative advocacy. Based on these findings, we discuss the theoretical and practical implications.     

Liberalization and changing spatial configurations in Nigeria’s domestic air transport network

In realization of the increasingly important role played by air transport, the Nigerian government followed the global trend of deregulation in reforming its domestic airline industry in 1985. Some of the effects of deregulation have been consistent with observed trends in other countries but others have been quite different. The abandonment of less profitable routes in the short term as well as the unfolding core-periphery structures following the emergence and dominance of certain core control centers replicates what obtained in the United States. However, evidence from literature suggesting that liberalization in practice has often resulted in the rising concentration of connectivity in a limited number of nodes and links rather than in its dispersal over the network at large does not hold yet in Nigeria’s domestic air network. This paper shows that the shifting balance between concentration and dispersal in Nigeria’s domestic network is generally skewed towards dispersal. Passenger traffic is more dispersed among nodes as gleaned from diminishing standard deviation values with increasing number of nodes. Generally speaking, overall connectivity also tends towards more evenness in the network since deregulation.     

Capacities,innovation and feedbacks in production networks in Argentina

This paper is based on an application of the complex systems approach to economics with the objective of exploring the micro- and meso-mechanisms of development. Under this approach, innovation can be seen as an emergent property that depends on micro interaction and on specificities of macro structure. This study emphasizes that the micro interactions can be described by the feedback mechanisms between the absorption and connectivity capacities of firms, and the macro structure by processes of creative destruction, knowledge appropriation and structural change. The paper presents empirical evidence on the feedback loops between absorption and connectivity capacities in production networks in Argentina and their impact on innovation results. This paper concludes that the restrictions on absorption capacity and mainly on connectivity capacity in several production networks in Argentina condition the development of positive feedbacks between the two capacities, and hence the scope of the innovation path.     

Trade and transport connectivity: a spatial approach

This article aims to analyse whether transport connectivity affects trade flows using a spatial approach. We consider first-order contiguity and incorporate logistics network structure dependence in a spatial autoregressive model. The results provide evidence regarding the role of the location of logistics platforms for satisfying existing demand for transport structure in Spain.     

Connectivity analysis of transshipments at a cargo hub airport

The paper investigates the interconnectivity of airfreight networks as temporal concentrations at airport. The connectivity of freight transshipments depends on both the quality of connections at hub airports and the quality of indirect flights compared to direct flights. Here connectivity of flight schedules is analyzed using a temporal wave structure to estimate the degrees of connectivity and the quality of connectivity.
