Abstract In this paper a very natural generalization of the two-way analysis of variance rank statistic of F riedman is given. The general distribution-free test procedure based on this statistic for the effect of J treatments in a random block design can be applied in general two-way layouts without interactions and with different numbers of the continuous observations per cell provided the design scheme is connected. The asymptotic distribution under the null hypothesis of the test statistic is derived. A comparison with the method of m rankings of B enard and van E lteren is made. The disadvantage of B enard and van E lteren's test procedure is that the number of observations per block does influence the statistic twice, namely firstly by the number itself, as it should, and see ondly by the level of the ranks which will be different in different blocks if the numbers of observations per block are different. The proposed test statistic is not sensitive to differences in the levels of the ranks caused by the different numbers of observations per block. The test is derived from considerhg the K ruskal -W allis statistics per block.
Finally, the results of simulation experiments are given. The simulation is carried out for three designs and a number of normal location alternatives and gives some information about the power of the suggested test procedure. A comparison is made with B enard and van E lteren's test and with the classical analysis of variance technique. For some simple orthogonal designs the exact null distributions of B enard and van E lteren's test and the proposed test are compared. 相似文献

Institutional, or sector-by-sector input–output tables have traditionally been used in regional and interregional modelling. This paper examines the origins of this tradition and argues instead, both theoretically and empirically, for the integration of make and use submodels within models of production, demand and interregional trade, outlining the manner in which they can be integrated. Further, it is argued that structural rather than reduced-form models represent a sounder theoretical base. Finally, a Danish interregional model (LINE) based on a social accounting matrix framework that employs these principles is presented. The paper also deals with the issue of data construction at the regional and interregional levels, based on the make and use approach. It is argued that when data are constructed at a low level of sectoral and spatial aggregation under accounting consistency constraints, data quality and validity are high. 相似文献

ABSTRACTBalancing social and economic missions in the pursuit of growth is one of the greatest challenges faced by social ventures. Although social ventures strive for growth to scale their social impact, pursuing growth often results in mission drift and the sacrifice of social objectives, which in turn eventually undermine the ventures’ raison d’être. In this study, we investigate how and with what outcomes social ventures that pursue growth can manage the balance of social and economic missions. Through a comparative case study of six for-profit social ventures, we find significant differences in how dual missions are selected, connected, and intertwined, leading to varying degrees of mission spillover effects between social and economic missions. Our findings show that two-sided mission spillover effects are a central mechanism in dual mission management, enabling social ventures to pursue balanced growth, avoid mission drift, and achieve social impact. With these findings, this study adds to the emergent literature on social entrepreneurship, dual mission management, and social venture growth. 相似文献

We apply the ethnographic tools of economic anthropology to analyse a particular ritual performed by the high priest of the Arbee sub‐tribe in the South Pacific island group of Aotearoa. (In other island groups, this high priest is sometimes known as the Governor of the Reserve Bank of New Zealand.) The ritual is considered by many within Aotearoa to be the cause of The Imbalance in The Economy. We analyse this claim and show that it has similarities (and equal validity) to claims of other cargo cults within the South‐West Pacific region. 相似文献

Previous studies that have assessed the short-run and the long-run effects of exchange rate changes on Turkey’s trade balance with its major partners relied upon a linear adjustment process that could not find much support for favorable effects of exchange rate changes. In this paper, once we separate real appreciations from real depreciations via the partial sum concept and introduce nonlinearity into the estimation and testing procedure, we show that the effects of exchange rate changes are asymmetric. More precisely, while lira appreciation does not have any significant effects on Turkey’s bilateral trade balances, lira depreciation has significantly favorable effects on Turkey’s trade balance with its European partners (France, Germany, Italy, Portugal, and Great Britain). 相似文献

Past studies in supply chain management have focused on dyadic relationships (e.g., buyer–supplier), as all relationships in a network begin with a dyad. However, dyads do not capture the essence of a network. We posit in this paper that triads are the fundamental building blocks of a network. To begin considering triads in supply networks, we build on two extant bodies of literature — the buyer–supplier relationship and supplier–supplier relationship literature which offer us the context of buyer–supplier–supplier triads. By doing so, we are taking the first step toward cracking the internal dynamics of triads in supply networks. To build theoretical propositions, we apply balance theory and the structural‐hole concept. We identify nine triadic archetypes of buyer–supplier–supplier relationships and state key propositions that aid in decision making in supply networks. 相似文献

While an increasing number of studies focus on work–family balance (WFB), little research has examined WFB in China. We aim to fill this gap by exploring the antecedents to WFB for Chinese employees. On the basis of the WFB model, we propose that servant leadership positively influences WFB through identification with the leader and work‐to‐family positive spillover (WFPS). We conducted a field survey in an insurance company in Shanghai. Two hundred salespersons with an average age of 32.5 were surveyed (116 women and 84 men). The results indicate that perceived servant leadership indirectly promotes WFB. The positive relationship between servant leadership and WFB is mediated by identification with the leader and WFPS, which operate in tandem. We discuss the theoretical and managerial implications of our findings. 相似文献
