New development: Private finance over public good? Questioning the value of impact bonds

This article contrasts the proposed benefits of social impact bonds (SIBs) with the more mixed performance of initial projects, and reviews the early literature, revealing a similar divide between initial optimism and subsequent critique. Despite this, SIBs continue to receive high-level support, while expanding their reach through controversial new ‘development’ and ‘environmental’ impact bonds. This situation deserves more scrutiny in the accounting literature.

Local Powers of Optimal One‐sample and Multi‐sample Tests for the Concentration of Fisher‐von Mises‐Langevin Distributions

One‐sample and multi‐sample tests on the concentration parameter of Fisher‐von Mises‐Langevin distributions on (hyper‐)spheres have been well studied in the literature. However, only little is known about their behaviour under local alternatives, which is due to complications inherent to the curved nature of the parameter space. The aim of the present paper therefore consists in filling that gap by having recourse to the Le Cam methodology, which has recently been adapted from the linear to the spherical setup. We obtain explicit expressions of the powers for the most efficient one‐ and multi‐sample tests. As a nice by‐product, we are also able to write down the powers (against local Fisher‐von Mises‐Langevin alternatives) of the celebrated Rayleigh test of uniformity. A Monte Carlo simulation study confirms our theoretical findings and shows the empirical powers of the above‐mentioned procedures.     

第三方支付相关基础法律问题探讨

第三方支付不是单纯的货币转移支付,而是与商业交易密切相关。互联网支付是典型的"担保支付",第三方为付款人的货币支付和收款人的货物交付进行了担保,有效保证了交易合同的全面履行,付款人支付的货币资金具有反担保保证金性质;预付卡支付和银行卡收单支付都是委托代理支付,预付卡支付第三方收到付款人的货币资金属于保管行为。

Inked: historic African-American beach site as collective memory and group ‘Third Place’ sociability on Martha’s Vineyard

Using data gained from ethnographic research and interviews, this article examines ‘third place’ sociability in the social interactions of the Polar Bears of Martha’s Vineyard, a group of predominantly but not exclusively middle-aged and senior African-American men and women who swim, exercise and socialise together each morning at ‘the Inkwell’ beach. Using Georg Simmel’s concept of sociability and Ray Oldenburg’s third-place theoretical framework, this study explores the key role of the Monday communal breakfast and the function of conversation in establishing bonds between individuals. It further investigates the promotion of strong feelings of social connectedness, belonging, social support, social capital gains and community among its group members. The ongoing sociability and informal rules of the Polar Bears of Martha’s Vineyard has enabled it to become a model group demonstration of third-place community building. The importance of race, class and place is socio-historically investigated within the broader social context of the popular racialised section of the beach, ‘the Inkwell’, of African-American community life, and within the sub-community milieu of group social interaction.
