Synergies and conflicts in the use of policy and planning instruments for implementing forest and woodland corridors and networks; a case study in NE Scotland

José Muñoz-Rojas, Maria Nijnik, Marc González-Puente, Felipe Cortines-García, more

Forest Policy and Economics > 2015 > 57 > Complete > 47-64

The policy and planning framework for land use in Scotland has undergone major changes since political devolution began in 1998. The latest reforms have set numerous objectives related to semi-natural, rural and urban landscapes, with a key role attributed to the expansion of corridors and networks. In this paper, we examine the feasibility of the Scottish forest policy and planning framework to drive...

An analytical framework for supply network risk propagation: A Bayesian network approach

Myles D. Garvey, Steven Carnovale, Sengun Yeniyurt, M.D. Garvey, more

European Journal of Operational Research > 2015 > 243 > 2 > 618-627

There are numerous examples of supply chain disruptions that have occurred which have had devastating impacts not only on a single firm but also on various other firms in the supply network. We utilize a Bayesian Network (BN) approach and develop a model of risk propagation in a supply network. The model takes into account the inter-dependencies among different risks, as well as the idiosyncrasies...

Network regulation and regulatory institutional reform: Revisiting the case of Australia

Rabindra Nepal, Flavio Menezes, Tooraj Jamasb, R. Nepal, more

Energy Policy > 2014 > 73 > Complete > 259-268

It is well-understood that the success of liberalizing the electricity supply industry depends crucially on the quality and design of the regulatory and institutional framework. This paper analyses the regulatory arrangements that underpin the work of the Australian Energy Regulator (AER). These arrangements are contrasted with the regulatory structure of electricity provision in Norway. A key difference...

International standards and international trade: Empirical evidence from ISO 9000 diffusion

Joseph A. Clougherty, Michał Grajek, J.A. Clougherty, M. Grajek

International Journal of Industrial Organization > 2014 > 36 > Complete > 70-82

Empirical scholarship on the standards–trade relationship has been held up due to methodological challenges: measurement, varied effects, and endogeneity. Considering the trade-effects of one particular standard (ISO 9000), we surmount methodological challenges by measuring standardization via national penetration of ISO 9000, allowing standardization to manifest via multiple (quality-signaling, information/compliance-cost,...

Communication in repeated network games with imperfect monitoring

M. Laclau, M. Laclau

Games and Economic Behavior > 2014 > 87 > Complete > 136-160

I consider repeated games with private monitoring played on a network. Each player has a set of neighbors with whom he interacts: a player's payoff depends on his own and his neighbors' actions only. Monitoring is private and imperfect: each player observes his stage payoff but not the actions of his neighbors. Players can communicate costlessly at each stage: communication can be public, private...

Network geometry and the urban railway system: the potential benefits to geographers of harnessing inputs from “naive” outsiders

Gabriel Dupuy, G. Dupuy

Journal of Transport Geography > 2013 > 33 > Complete > 85-94

This paper considers a form of scientific interdisciplinarity that brings the experts in one discipline or field into play with uninitiated outsiders from other, unrelated, disciplines - what Edgar Morin might call ''naive interdisciplinarity''. The discipline here is network geography and the field the urban railway system (URS), which has benefitted from some significant contributions from ''naive''...

Dantzig-Wolfe Reformulation for the Network Pricing Problem with Connected Toll Arcs

Bernard Fortz, Martine Labbé, Alessia Violin, B. Fortz, more

Electronic Notes in Discrete Mathematics > 2013 > 41 > Complete > 117-124

This paper considers a pricing problem on a network with connected toll arcs and proposes a Dantzig-Wolfe reformulation for it. The model is solved with column generation and the gap between the optimal integer value and the linear relaxation optimal value is shown to be at least as good as the one from the mixed-integer formulation proposed in the literature. Numerical results on different sets of...

Communication channels, innovation tasks and NPD project outcomes in innovation-driven horizontal networks

Adegoke Oke, Moronke Idiagbon-Oke

Journal of Operations Management > 2010 > 28 > 5 > 442-453

Inter-organizational collaborations and horizontal networks are increasingly playing a pivotal role in innovations and new product development among firms. In this study, we investigate the link between the innovation task analyzability and the richness of communications channels used in network arrangements and the link between task analyzability and ties and project development time. We investigated...

Fractal dimensions of percolating networks

Reuven Cohen, Shlomo Havlin

Physica A: Statistical Mechanics and its Applications > 2004 > 336 > 1-2 > 6-13

We use the generating function formalism to calculate the fractal dimensions for the percolating cluster at criticality in Erdos-Renyi (ER) and random scale free (SF) networks, with degree distribution P(k)=ck ^- ^λ . We show that the chemical dimension is d _l =2 for ER and SF networks with λ>4, as in percolation in d>=d _c =6 dimensions. For 3<λ<4 we show that...

Complexity organization of resting‐state functional‐MRI networks

Gabriel Trevino, John J. Lee, Joshua S. Shimony, Patrick H. Luckett, more

Human Brain Mapping > 45 > 12 > n/a - n/a

Entropy measures are increasingly being used to analyze the structure of neural activity observed by functional magnetic resonance imaging (fMRI), with resting‐state networks (RSNs) being of interest for their reproducible descriptions of the brain's functional architecture. Temporal correlations have shown a dichotomy among these networks: those that engage with the environment, known as extrinsic,...

Two‐sample testing for random graphs

Xiaoyi Wen

Statistical Analysis and Data Mining: The ASA Data Science Journal > 17 > 4 > n/a - n/a

The employment of two‐sample hypothesis testing in examining random graphs has been a prevalent approach in diverse fields such as social sciences, neuroscience, and genetics. We advance a spectral‐based two‐sample hypothesis testing methodology to test the latent position random graphs. We propose two distinct asymptotic normal statistics, each optimally designed for two different models—the elementary...

Mindfulness networks: Analyzing associations with self‐compassion, other‐compassion, need fulfillment, and satisfaction in midlife married Canadians

Christopher Quinn‐Nilas, Robin R. Milhausen

Personal Relationships > 31 > 2 > 578 - 602

Interest in mindfulness in the field of romantic relationships is growing. Drawing from a Self‐Determination Theory (SDT) perspective—which proposes that the basic psychological needs for autonomy, competence, and relatedness are foundational for well‐being—we attempted to map out the complex associations between mindfulness, self‐compassion, other‐compassion, basic need fulfillment in relationships,...

Asserting and transcending ethnic homophily: How entrepreneurs develop social ties to access resources and opportunities in socially contested environments

Christian Busch, Robert Mudida

Strategic Entrepreneurship Journal > 18 > 2 > 229 - 257

Research Summary In socially contested settings, it is often difficult to connect with (diverse) others, and it is unclear how entrepreneurs in these contexts may develop the social ties that previous research has shown to be valuable. We studied this subject matter in Kenya, an ethnically fractionalized society that recently experienced the decentralization of government, which required entrepreneurs...

Flexible parametrization of graph‐theoretical features from individual‐specific networks for prediction

Mariella Gregorich, Sean L. Simpson, Georg Heinze

Statistics in Medicine > 43 > 13 > 2592 - 2606

Statistical techniques are needed to analyze data structures with complex dependencies such that clinically useful information can be extracted. Individual‐specific networks, which capture dependencies in complex biological systems, are often summarized by graph‐theoretical features. These features, which lend themselves to outcome modeling, can be subject to high variability due to arbitrary decisions...

Offshore FDI, tax havens, and productivity: A network analysis

Soni Jha, Snehal Awate

Global Strategy Journal > 14 > 2 > 350 - 382

Research summary Multinational enterprises (MNEs) use tax havens to benefit from international tax arbitrage and increase their capital efficiency. These activities are purported to distort global financial markets, erode national corporate tax bases, and are singularly targeted in the media. Despite this, MNEs continue to increase the dispersion of their tax haven activities by investing in multiple...
