If governance has become, for many years, as a matter of paramount importance in traditional companies (Berle & Means, 1932), microfinance institutions have also not escaped this need (Rock et al. 1998), there are about thirty years. Considered essential to address issues related to economic and social development (Wélé, 2009), governance is also emerging as an undeniable factor for to strengthen the financial performance and to increase awareness in microfinance institutions (Rock et al., 1998; Labie, 2001 Helms, 2006). Several authors have contributed to the understanding of corporate governance by using a variety of theoretical approaches (Jensen & Meckling (1976), Fama and Jensen (1983a) for Shareholders approach, Freeman (1984), Donaldson & Preston (1995) Hung (1998) for the stakeholder approach, Meyer and Rowan (1977), Mertens (2010), Muth & Donaldson (1998), Berle & Means (1932); Labie (2005a) for alternative approaches). Applied individually in cooperatives and organizations, these approaches have proved rather one-dimensional and illuminate one aspect of the Boards of Directors (Cornforth, 2004). Hence the need for an approach that integrates the insights of these perspectives has been felt. Thus, a perspective in terms of paradox (Cornforth, 2004) helped to highlight the dilemmas, paradoxes and tensions that boards of directors are facing. Several researchers have used this paradox perspective in different organizations (Demb & Neubauer, 1992 Wood, 1996; Sundaramurthy & Lewis, 2003), but it also did not take long. Criticized for focusing only on the board, this perspective paradox is also alleged to ignore the role of contextual factors. However, as argued by DiMaggio & Powell (1983), Meyer and Rowan (1977), environmental factors play an undeniable role in the way organizations make isomorphic. Rijpens & Adam (2011) also point out that the internal and external factors to the organization involved in the debate on the governance model adopted. Hudon and Seibel (2007) argue that conflicts and disasters seriously affect the socio-economic institutions, public governance, networks and social relations of citizens, including those related to the exchange or transfer of financial resources. This article examines the influence of armed conflict on the cooperatives’ governance. It is built around three fundamental questions. (1) What overlay the systems of cooperatives governance? (2) What is the theoretical model of governance adapted to cooperatives working in conflict situations? (3) How an armed conflict does it influence the cooperatives governance? To answer these questions, this article assumes, first, the confrontation of existing theoretical approaches in the literature on corporate governance in general and cooperatives in particular. It then develops a model of governance adapted to the conflict. Finally, that model will be tested after data collect from a qualitative field study based on the triangulation of information resources and interviews with key players in organizations under study in a country where microfinance institutions have evolved conflict situations. The results will be presented in another article. [less ▲]

Several studies on the sources of funding for local NGOs in Africa highlight their dependence on foreign donors, while in developed countries, these organizations have multiple resources. Investigations previously done show that the majority of resources of local NGOs come from foreign donors, and most of them are dead at inception due to lack of funding. Before reaching the beneficiaries, financing goes through several players who are related by an explicit contract: Foreign donors - International NGOs - Local NGOs - Endogenous groups - beneficiaries populations. The literature points to the existence of a contractual relationship between the one who runs the activities and the one that funds them. Yet despite this explicit contract, some actors in this chain of relationships are influenced by other factors and / or their interests and make decisions that have no direct links with the mission of the organization. This leads us to ask ourselves two questions: first, the question about the factors that characterize the relationship between actors and secondly whether at all levels, the actors involve other stakeholders. The present paper aims to provide a conceptual and theoretical framework to characterize the agency chain relationship between these different actors. Although there are studies on the application of the agency theory in the governance of Nonprofit organizations, there have been very few studies done on the agency chain relationship between these organizations. It is then necessary to make new theoretical developments on how local NGOs in Africa in general, and Burundi in particular, are funded and governed; and that, in the case where the actors in the chain relationship are in different contexts. To do this, we will first mobilize and apply the agence theory and others theories of governance at this agency chain relationship. We conclude by showing the peculiarity of Africa in general, and Burundi in particular with additional elements that enhance this agency relationship, making then the conceptual model complex.

Senegalese consumers seem to prefer local fresh milk-based dairy products rather than the ones produced with imported powder. However, market prices of both products do not appear to be different. This paper addresses this puzzle. First, I confirm the preference for local products. Using choice-based-conjoint data, I evaluate that Senegalese consumers are willing to pay a positive and significant premium for these products. Then, I identify the determinants of prices, based on a unique dataset of milk products characteristics. Evidence suggests that consumers' misinformation regarding the product composition prevents them from allocating a higher price to local milk-based products. [less ▲]

IT organization design, consisting of IT governance (decision rights) and IT organization structure, is believed to affect organizational performance. This paper describes the IT organization design choices of the 50 U.S. state governments. Significant movement toward greater centralization was observed (particularly for IT services). States appeared to have adopted IT organization design innovations previously pioneered in the private sector, contrary to conventional wisdom founded on well-documented differences between the two sectors. Two commonly used explanations of IT organization design choices were examined for their ability to account for the unexpected findings — contingency and institutional theories. Both explanations were partially successful in explaining the results, but further theoretical development is needed to integrate those theories and more empirical research is needed to advance the field’s knowledge of IT organization design.

Ce 1er juillet 2013, après six années de négociations avec l’Union européenne (UE) et de réformes laborieuses, la Croatie deviendra le 28ème État membre à part entière de la famille européenne. Après la Slovénie, membre depuis 2004, il s’agit du deuxième pays sortant de la dissolution violente de l’ex-Yougoslavie à rejoindre l’UE. Contrairement à son voisin slovène où les hostilités n’ont duré que quelques jours, la Croatie a connu plusieurs années de guerre et de destruction. Raison pour laquelle elle a été confrontée à une longue période de transition. Depuis son indépendance en 1991, tous les gouvernements croates ont engagé, un processus de consolidation de leur État. Ensuite ils ont consacré leur force à l’adhésion de leur pays à l’Organisation du traité de l’Atlantique Nord (OTAN), concrétisée en 2009, enfin ils ont travaillé à leur entrée dans l’UE.

The meter-per-second precision achieved by today velocimeters enables the search for 1-10 M_Earth planets in the habitable zone of cool stars. This paper reports on the detection of 3 planets orbiting GJ163 (HIP19394), a M3 dwarf monitored by our ESO/HARPS search for planets. We made use of the HARPS spectrograph to collect 150 radial velocities of GJ163 over a period of 8 years. We searched the RV time series for coherent signals and found 5 distinct periodic variabilities. We investigated the stellar activity and casted doubts on the planetary interpretation for 2 signals. Before more data can be acquired we concluded that at least 3 planets are orbiting GJ163. They have orbital periods of P_b=8.632+-0.002, P_c=25.63+-0.03 and P_d=604+-8 days and minimum masses msini = 10.6+-0.6, 6.8+-0.9, and 29+-3 M_Earth, respectively. We hold our interpretations for the 2 additional signals with periods P_(e)=19.4 and P_(f)=108 days. The inner pair presents an orbital period ratio of 2.97, but a dynamical analysis of the system shows that it lays outside the 3:1 mean motion resonance. GJ163c, in particular, is a super-Earth with an equilibrium temperature of T_eq = (302+-10) (1-A)^(1/4) K and may lie in the so called habitable zone for albedo values (A=0.34-0.89) moderately higher than that of Earth (A_Earth=0.2-0.3).

Today, personal computers are part of our life either at home, at work or at school. Even if the computer power increases, the software are more and more complicated, asking more and more time for learning it or for obtaining a result. It becomes important to have in labs as well as at school small fast software using empirical equations. We report here about the use but more particularly the algorithms, the equations and the data sets of three software belonging to the Gabriel package. The first one, Gabriel Nathalie II, is a calculator with many functionality's. It is possible to calculate the pKa or to simulate the chemical shift in 31P NMR of amino-phosphonate. Moreover it is also able to dertimine the thermodynamics data of bisphosphonate binding to human bones. The second one, Gabriel Calculatrice Savon, is used to calculate the amount of alkali needed for making a soap according to the amount and the nature of fat but also the viscosity of some oils at a desired temperature. And at least Gabriel Data Analysis is a software devoted to data analysis. Today, software for research can be used for educational and educational software can be useful for research. [less ▲]

We consider a special class of axial multi-dimensional assignment problems called multi-dimensional vector assignment (MVA) problems. An instance of the MVA problem is defined by $m$ disjoint sets, each of which contains the same number $n$ of $p$-dimensional vectors with nonnegative integral components, and a cost function defined on vectors. The cost of an $m$-tuple of vectors is defined as the cost of their component-wise maximum. The problem is now to partition the $m$ sets of vectors into $n$ $m$-tuples so that no two vectors from the same set are in the same $m$-tuple and so that the total cost of the $m$-tuples is minimized. The main motivation comes from a yield optimization problem in semi-conductor manufacturing. We consider two classes of polynomial-time heuristics for MVA, namely, hub heuristics and sequential heuristics, and we study their approximation ratio. In particular, we show that when the cost function is monotone and subadditive, hub heuristics, as well as sequential heuristics, have finite approximation ratio for every fixed $m$. Moreover, we establish better approximation ratios for certain variants of hub heuristics and sequential heuristics when the cost function is monotone and submodular, or when it is additive. We provide examples to illustrate the tightness of our analysis. Furthermore, we show that the MVA problem is APX-hard even for the case $m=3$ and for binary input vectors. Finally, we show that the problem can be solved in polynomial time in the special case of binary vectors with fixed dimension $p$. [less ▲]

It is generally thought that galaxies are embedded in dark matter halos extending well beyond their luminous matter. The existence of these galactic halos is mainly derived from the larger than expected velocities of stars and gas in the outskirts of spiral galaxies. Much less is known about dark matter around early-type (elliptical or lenticular) galaxies. We use gravitational lensing to derive the masses of early-type galaxies deflecting light of background quasars. This provides a robust measurement of the total mass within the Einstein ring, a circle whose diameter is comparable to the separation of the different quasar images. We find that the mass-to-light ratio of the lensing galaxies does not depend on radius, from inner galactic regions out to several half-light radii. Moreover, its value does not exceed the value predicted by stellar population models by more than a factor two, which may be explained by baryonic dark matter alone, without any need for exotic matter. Our results thus suggest that, if dark matter is present in early-type galaxies, its amount does not exceed the amount of luminous matter and its density follows that of luminous matter, in sharp contrast to what is found from rotation curves of spiral galaxies.

Entre 2010 et 2012, une étude complexe a été menée pour apporter des éléments qualitatifs et quantitatifs fiables sur l’évolution de la ressource ligneuse sur le bassin d’approvisionnement en bois énergie de Kinshasa. Cette étude pluridisciplinaire (Figure 1) a mobilisé l’analyse d’images satellites, la cartographie, les inventaires forestiers, la dendrométrie, des études sur la carbonisation traditionnelle et la compréhension des dynamiques sociales et économiques des zones d’étude. En plus d’analyser l’évolution de la couverture forestière sur la période de suivi (1984-2012), ce travail a permis de quantifier pour la première fois, sur des bases scientifiques et des méthodologies solides, les stocks de biomasse aérienne et de carbone ainsi que leur évolution. Après calage avec les standards REDD+, ces informations devraient se révéler très utiles dans la perspective des futurs projets REDD+ en Afrique centrale. Cette étude couvre une superficie de 900 000 ha située sur le plateau Batéké et au Bas Congo.

This paper focuses on an apparent disconnect between the literatures on 1) the governance of IT decisions and the organization of IT activities inside organizations and 2) IT outsourcing decisions and IT outsourcing governance arrangements between client organizations and IT service providers. We hypothesize that centralization of IT activities within organizations is a necessary precondition for outcomes such as IT consolidation (leading to large cost efficiencies) and outsourcing deals and possibly also for successful consolidation and outsourcing. We investigate this hypothesis through an exploratory, mixed-method investigation of changes in IT governance arrangements and outcomes in a single, well-defined population of organizations — the executive branches of US State governments.

Cross-sectional sampling is often used when investigating inter-event times, resulting in left-truncated and right-censored data. In this paper we consider a semiparametric truncation model in which the truncating variable is assumed to belong to a certain parametric family, while nothing is assumed on lifetime and censoring distributions. The novelty of this work is in the fact that it introduces estimators of this semiparametric model in the presence of censoring. Two alternative methods are considered, based on conditional and full likelihood considerations. Asymptotic representations of the estimators for the lifetime distribution are obtained, and their weak convergence is established. The finite sample performance of the new estimators is explored through simulations, and two real data illustrations are provided. One of the conclusions of our research is that both estimators perform better than Wang's NPMLE when the parametric family for the truncation variable is valid) in the sense of the integrated mean squared error, and that the full likelihood approach is preferable to the conditional likelihood approach for the estimation of the lifetime distribution but not necessarily for the estimation of the truncation distribution.

This paper is divided into two sections. The first aims to offer a thorough discussion of the agyieus and of types of altar for Arsinoe Philadelphos as well as of the offerings devoted to her in the Ptolemaic kingdom. The second explores the relationship that exists between the agyieus and the creation of cultic double names of Arsinoe in the streets of Alexandria. By combining the evidence on Arsinoe’s altars with a set of legal papyri attesting her divine names in Alexandria, I argue that in the Ptolemaic capital, the agyieis had a twofold function. They served firstly, as cult places for Arsinoe and secondly, as city landmarks. I will also argue that the second function of the agyieis, as city landmarks, survived the Ptolemaic cult of the Philadelphos and was ultimately preserved in long-lasting toponyms. [less ▲]

The postal sector has undergone dramatic changes over the recent years under the double effect of ongoing liberalization and increased competition with alternative communication channels (e-substitution). As a result, the mail volume handled by the historical operator has declined sharply while the latter's ability to match the same standard of universal service may be under threat. Thus, a reform of the postal universal service is on the agenda. This paper examines possible reforming options ranging from keeping universal service within the postal sector to redefining universal service as spanning postal and electronic technologies.

Traditional economic theories of social enterprises rely on new institutional economics. Although these theories have an undeniable explanatory power, they display a series of non-negligible flaws. Evolutionary and complexity approaches in economics may help overcome these limits. The object of this article is, in a first time, to review the different new institutional theories applied to non-profits and cooperatives and, in a second time, to present some criticisms addressed to new institutional economics. We concentrate on two controversial aspects of the latter: on the one hand, its underlying hypotheses about individuals and, in particular, bounded rationality and opportunism; on the other hand, its neglect of the emergent and evolving nature of economic phenomena and of the importance of history and the environment in agents’ institutional choices. For each criticism, we make proposals, mainly inspired by evolutionary and complexity approaches in economics, in order to overcome these limits. [less ▲]

There is strong scientific interest in Ganymede (Jupiter's third Galilean moon) and its surrounding environment, which stems from the likely presence of a liquid water ocean underneath its icy crust and from its internally driven magnetic field. The interaction of the latter with Jupiter's magnetospheric plasma and its magnetic field gives rise to a unique situation in our solar system implying a mini-magnetosphere embedded within a giant-magnetosphere. This interaction generates Ganymede's ultraviolet auroral footprint in Jupiter's atmosphere. We propose to investigate the strong auroral connection between Jupiter and Ganymede and the variable characteristics of Ganymede's magnetosphere with an innovative approach, taking advantage of the large scale north-south asymmetries of Jupiter's magnetic field. The results obtained for Ganymede will be compared with the case of small injected hot plasma bubbles observed by the Galileo spacecraft and whose size and location are similar to those of Ganymede's magnetosphere. HST is currently the sole instrument capable of obtaining this information which pins down the proposed mechanisms linking the source and sink regions of auroral particles in the giant planets' magnetospheres.

Many Belgian retire well before the statutory retirement age. Numerous exit routes from the labor force can be identified: old‐age pensions, conventional early retirement, disability insurance, and unemployment insurance are the most prominent ones. We analyze the retirement decision of Belgian workers adopting an option value framework, and pay special attention to the role of health status. We estimate probit models of retirement using data from SHARE. The results show that health and incentives matter in the decision to exit from the labor market. Based on these results, we simulate the effect of potential reforms on retirement. [less ▲]

We propose a Dynamic Hierarchical Factor Model using Asset classes to predict mutual funds excess returns. We use different forecast combination schemes of bivariate model considering each asset class factor in isolation. Primary analysis highlights the importance to account for asset class specific variations together with between classes or common variations. Further refinements of the a priori repartition are however in order. Forecasting performance of the model outperforms the historical mean benchmark both in terms of MSPE and utility based criteria. A forecasting exercise matching more closely real-time conditions must be undertaken to validate these initial results. [less ▲]

Abstract : Belgian family luxury Houses are increasingly confrontated to a problem of independence caused by the growing influence of great financial groups and of private investment funds, on the one hand, and by a problem of image due to their Belgian origin, on the other hand. Nevertheless, their growing need for internationalization in order to counter the threats of the market and to seize opportunities leads them to concede one part of their control to institutional investors. The interest of this research is to study the potential impact, as perceived by the leaders of Belgian luxury Houses, of the venue of public institutional investors in their capital structure. We show that this perceived impact oscillates between sacralization and diabolisation of public institutional investors. [less ▲]

In this paper, we compare Morningstar ratings with those obtained using the same methodology of rating attribution with a set of commonly used performance measures. We look at three types of investment horizons: 3-year, 5-year and 10-year ratings. Our analysis focuses on Open-End US Mutual Funds available in Morningstar Direct Database from which we create three sets of 16,617, 13,505 and 7,992 funds corresponding respectively to the three investment horizons analyzed. Our results show that Morningstar ratings are very close (correlation around 80%) to ratings obtained with Sharpe’s alpha, Jensen’s alpha, Four-factor alpha and Excess returns. And less significantly, we also observe that ratings given by the Sortino ratio, Sharpe MVaR, M-squared, Sharpe ratio, One-factor information ratio, Four-factor information ratio, Prospect ratio and Stutzer index are quite similar to Morningstar’s ratings (correlation lying between 70% and 78%). At the other end of the spectrum, however, ratings obtained with Annual return diverge widely from Morningstar ratings. We also analyse which explanatory variables can explain the differences between ratings computed with Morningstar as compared with the alternative performance measures using a probit regression. We find that Load adjustments, tax and risk included by Morningstar in the computation of MRAR are often determining. Expense ratio, Return Skewness and the three factors of the Fama-French model (Beta, Size load and Book-to-market loading) can be significant determinants depending on the performance measure analyzed and on the selected investment horizon. Fund characteristics such as Age, Fund size, Turnover rate and Manager tenure are not statistically significant in determining the differences in ratings. Besides, we analyze differences between ratings (in terms of number of STARs) and we confirm previous results (i.e. the link between Morningstar’s and the alternative performance measures, but also the explanatory capacity of the load for lots of differences between ratings). Finally, we test all possible combinations of our set of performance measures, and observe that Sharpe’s alpha, excess return, Sharpe MVaR, Four-factor alpha and Jensen’s alpha are part of the best combinations. As a conclusion, Morningstar ratings can be replicated using simple and traditional performance measures but the replication is less accurate when tax and loads features are important. Therefore, Morningstar data management and access bring the most of its ratings’ value added. [less ▲]

This paper examines the potential of economies of scale and scope among the African central securities depository institutions. We address whether the consolidation of settlement and custody activities of securities make these institutions efficient in light of the costs of service parameter. To do this, we rely on the translog cost function [introduced by Christensen et al. (1971)] and the constant elasticity of substitution of seven central securities depositories in Africa over the period 2004-2009. The results show the existence of significant economies of scale and scope in these institutions. The extent of these economies differs upon the size of the institution and the level of automation mechanisms to combine securities settlement and custody activities. Our findings also indicate that, unlike large institutions in countries such as South Africa and Mauritius, which have heavily invested in automation mechanisms, smaller institutions have higher service costs, which implies a need for consolidation of activities to reduce these costs.

The paper proposes an equilibrium asset pricing model that accounts of the incomplete information on returns distribution and investors' preferences. Only moments up to order four of unknown unconditional distribution can be observed, and the model does not impose that portfolio diversi fication or moments preference should hold. Using Chebyshev-type of inequalities, an intuitive risk measure (risk horizon) is introduced with reference to the speed of convergence of a security's mean return to its expectations. By an arbitrage argument, this risk measure is related to the horizon of treasury securities in a system of equations that allows the calibration of the model parameters using term structure information. In particular, the expected return on the market portfolio can be endogenously estimated inside this system. The model calibration on U.S. market data provides plausible parameters estimates and interesting cyclical patterns in the time series of the expected return. The empirical relevance of these estimates is examined with tests of statistical and economic predictive ability for stock excess returns. The results provide signi ficant evidence on the added value of the estimates when compared to popular predictors found in the literature (see a.o. Lettau and Ludvigson, 2001; Rapach and Wohar, 2006; Goyal and Welch, 2008). [less ▲]

The success of e-government is believed to depend in part on the organizational and institutional arrangements that governments enact for the management of their IT resources. This paper develops the conceptualization of IT management arrangements by considering possible interactions between two dimensions — 1) the organization of IT activities and 2) control over decisions about IT activities (also known as governance) — for each of two categories of IT activities — 1) IT projects (such as website development) and 2) IT services (such as the operation of networks). In addition, the paper provides preliminary empirical evidence obtained from applying this expanded conceptualization in the context of American state governments. Many states appear to employ centralization of IT activities to offset decentralization of IT control and vice versa. Consequently, neither dimension alone provides a good characterization of governmental IT management arrangements. These findings have the potential to enhance our understanding of the barriers to, and enablers of, e-government success. [less ▲]

This paper investigates the effect of market-wide liquidity on optimal portfolio allocations across US equity portfolios sorted by size and book-to-market characteristics. In particular, we consider a single-period investor with a relative risk aversion of 5, and use the nonparametric approach of Brandt (1999) to directly express optimal portfolio weights as functions of market-wide liquidity innovations. We find, first, that the effect of market-wide liquidity is a decreasing function of investment horizon. Second, this effect is stronger in allocations in the small stock portfolio and gets weaker as we move towards the large stock portfolio. Third, conditional allocations in risky asset(s) decrease and exhibit shifts towards more liquid and less risky assets as market-wide liquidity worsens. Overall, our results show that allocations based on market-wide liquidity as a signal capture many phenomena that have been identified by researchers in the US market, such as the so-called “flight-to-safety”, flight-to-quality” and “flight-to-liquidity” episodes. Furthermore, in an out-of-sample test, results demonstrate the superior performance of a strategy based on market-wide liquidity compared to a benchmark strategy. [less ▲]

Monitoring the hospital’s performance is evolving over time in search of more efficiency by integrating additional levels of care, reducing costs and keeping stuff up-to-date. To fulfill these three potentially divergent aspects and to monitor performance, healthcare administrators are using dissimilar management control tools. To explain why, we suggest to go beyond traditional contingent factors to assess the role of the different stakeholders (governments, patients, authorities, personnel and administrators) that are at the heart of any healthcare organization. So, the main interest of our empirical study is to appraise how healthcare managers can foster strategic “alignment” in chaotic environments. To investigate this subject, we rely first on seminal studies to appraise the role of the main healthcare players and their influence on some organizational attributes (essentially size, lifecycle, structure, climate and technology in use). We then consider the managerial awareness and the perception of a suitable management control system (MCS) to promote a strategy-focused organization. Our methodology is based on a qualitative approach of twenty-two case studies, lead in two heterogeneous environments (Belgium and Lebanon). This method allows to illustrate, for each healthcare player, its positioning within the healthcare systems. Thus, we define how its role, its perception and its responsiveness manipulate the organization’s internal climate and shape the design of the performance monitoring systems. Our findings are expected to add knowledge on the reasons of the choice of adequate management systems, within three different healthcare organizational structures: university, general/university and general hospitals.
