In Fair Trade (FT), as well as in other ‘mixed-form’ fields (Becchetti & Huybrechts 2008; Marwell & McInerney 2005), non-profit organizations and social enterprises have been partnering with large corporations over long time periods despite the presence of conditions that might be expected to destabilize such relationships. These conditions include striking differences in size, economic power, and organizational goals or ‘logics’. Given these asymmetries, the collaborations are typically seen as problematic and temporary because the stronger party (the corporation) will impose its (market) logics upon the weaker one (the social enterprise), leading to either instrumentalizing and corrupting the latter or to the breakdown of the collaboration. Whilst some of the literature on FT and other market-oriented social movements has tended to depict corporate participation as a threat to the original goals of the social movement and to the integrity of partnering social enterprises (e.g. Fridell et al. 2008; Reed 2009), there is evidence of a set of social enterprise-corporate relationships that persist over time and cannot be simply summarized as dominated by the sole corporate, market logic. These examples illustrate the emergence of new working relationships across the conventional divides between distinct sectors – the public, private, and civil society – that offer new approaches to managing power asymmetries and apparently conflicting logics – typically, in FT and more generally in social entrepreneurship, market and social justice/welfare logics (Battilana & Lee 2014; Defourny & Nyssens 2006; Huybrechts & Nicholls 2012; Smith et al. forthcoming). This leads to the following research question: Under what conditions can inter-organizational relationships emerge and be sustained despite power asymmetries and the presence of distinct, potentially conflicting, institutional logics? The analysis in this paper aims to extend theory by providing an alternative to more deterministic analyses of inter-organizational relationships that suggest that the more powerful actor will always impose its logics upon the less powerful organization thus undermining the persistence of the relationship over time. In the process, this research adds a new construct to existing theory around the resolution of conflict in institutional logics by suggesting that dynamic persistence is also evident in contrast to examples of conflict resolution through dominance, compromise, hybridization, synthesis, or relationship breakdown. Based on the analysis of the relationships between commercial buyers and FTOs, initially embodying market and social justice logics respectively, this paper proposes a set of key conditions under which dynamic persistence can be observed even in the presence of power asymmetries.

Fine operating rules for security control and an automatic system for their online discovery were developed to adapt to the development of smart grids. The automatic system uses the real-time system state to determine critical flowgates, and then a continuation power flow-based security analysis is used to compute the initial transfer capability of critical flowgates. Next, the system applies the Monte Carlo simulations to expected short-term operating condition changes, feature selection, and a linear least squares fitting of the fine operating rules. The proposed system was validated both on an academic test system and on a provincial power system in China. The results indicated that the derived rules provide accuracy and good interpretability and are suitable for real-time power system security control. The use of high-performance computing systems enables these fine operating rules to be refreshed online every 15 min. [less ▲]

We discuss raditiative-induced neutrino mass mechanisms. We first briefly discuss systematic one-loop level classifications, and then discuss two-loop classification schemes based on a diagrammatic decomposition of the Weinberg operator. We point out that both, the one and two-loop order systematic sorting provides an exhaustive guide for radiative neutrino mass models. [less ▲]

Solar-like oscillations have now been characterized for a large number of stars, thanks to asteroseismic data obtained recently by space missions. This has led to the determination of the global and internal properties of these stars. In particular, core rotation rates have been obtained for red-giant stars, which is of prime importance to progress in the modelling of the dynamical processes at work in stellar interiors. In this presentation, we discuss which constraints can be brought by these asteroseismic measurements on stellar models that include rotational effects. Similarly to the solar case, we show that an efficient mechanism is required for the transport of angular momentum in the radiative zones of red giants. The efficiency of this transport process can be determined by asteroseismic observations of red-giant stars. [less ▲]

Very large nonlinear unconstrained binary optimization problems arise in a broad array of applications. Several exact or heuristic techniques have proved quite successful for solving many of these problems when the objective function is a quadratic polynomial. However, no similarly efficient methods are available for the higher degree case. Since high degree objectives are becoming increasingly important in certain application areas, such as computer vision, various techniques have been recently developed to reduce the general case to the quadratic one, at the cost of increasing the number of variables. In this paper we initiate a systematic study of these quadratization approaches. We provide tight lower and upper bounds on the number of auxiliary variables needed in the worst-case for general objective functions, for bounded-degree functions, and for a restricted class of quadratizations. Our upper bounds are constructive, thus yielding new quadratization procedures. Finally, we completely characterize all ``minimal'' quadratizations of negative monomials. [less ▲]
