Technology deployment process model

Organisations frequently deploy a range of new or improved technologies in order to improve their performance (efficiency and effectiveness). However, the literature has thus far primarily investigated Information Technology (IT) deployment issues and success factors, which may not be relevant or sufficient in the context of other technology types. Moreover, the literature usually discusses high-level success factors without identifying relevant low-level activities and their interdependencies. Specific guidance on how such activities may best be arranged in a process model is also lacking. Based on a one-year-long ethnographic study and one in-depth case study in the Australian Defence Organisation, this paper presents a normative technology-neutral process model comprising 61 activities thought to be necessary and sufficient for effective technology deployment.     

Risk factor and industry effects in the cross-country comovement of momentum returns

This paper examines the sources of cross-country comovement of momentum returns over the 1975–2004 period. Using data on more than 17,000 individual firms across 100 industries from 40 countries, we document the profitability of country-neutral individual firm, industry, and industry-adjusted return momentum. We show that country-neutral momentum returns are significantly correlated across countries, the correlation is time-varying, and that comovement among industries cannot explain the comovement of country-neutral momentum returns. However, we find that standard risk factor models do explain a significant portion of the cross-country comovement of momentum returns, even though they do not explain average momentum returns.     

Geographic Portfolio Allocations,Property Selection and Performance Attribution in Public and Private Real Estate Markets

This article examines the effects of geographic portfolio concentrations on the return performance of U.S. public real estate investment trusts versus private commercial real estate over the 1996–2013 time period. Adjusting private market returns for differences in geographic concentrations with public markets, we find that core private market performance falls. Using return performance attribution analysis, we find that the geographic allocation effect constitutes only a small portion of the total return difference between listed and private market returns, whereas individual property selection within geographic locations explains, in part, the documented outperformance of listed versus private real estate market returns.     

联邦制森林治理:分权管理经验和潜在影响

80%以上的发展中国家和经济转轨国家正在进行着某种形式的分权试验。以11个国家(拥有全球森林总量60%以上)为例,简要描述了实施联邦制的主要林业国家当前的森林行政管理类型以及施政形式,认为分权后强化了跨部门联系的重要性,许多政府机构都介入了有关森林资源的各项决策;有效的森林治理取决于各种管理机构的能力;私营部门和民间组织在成功治理各种森林资源中也发挥着重要作用。从11国经验中分析了各种潜在优势、潜在危险,指出分权管理减少了中央政府的官僚和决策障碍,但会使全国性的政策协调、实施和监督变得困难。     

A quantitative analysis of poverty and livelihood profiles: The case of rural Rwanda

The paper applies a quantitative methodology to study poverty and livelihood profiles on the basis of a large set of variables. It takes the context of post-conflict rural Rwanda for a case study. By means of exploratory tools (i.e. principal component and cluster analysis), it combines variables that capture natural, physical, human, financial and social resources together with environmental factors to identify household groups with varying livelihoods. The paper further explores how these clusters differ with regards the incidence of poverty, livelihood strategies and their respective crop preferences. The paper concludes that Rwandan rural policies should adopt distinct and appropriate interventions for impoverished peasant groups, each having their own particular livelihood profiles.     

Partnership with and without trade unions in the UK financial services: filling or fuelling the representation gap?

Partnership theory proposes that an appropriate integration of direct and indirect employee participation mutually benefits the workers and the company. This study explores the putative employee voice gains and the risks for union effectiveness by comparing employees' evaluation of partnership practices at two financial service companies with non‐union and union employee representation, respectively.     

The Cross Section of Expected REIT Returns

In this study, we examine the cross-sectional determinants of expected REIT returns. We examine both the pre- and post-1990 periods, since the structure of the REIT market changed substantially around 1990. The determinants of expected returns differ between the two subperiods. In the pre-1990 subperiod, momentum, size, turnover and analyst coverage predict REIT returns. In the post-1990 period, momentum is the dominant predictor of REIT returns. Given the strength of the momentum effect in the post-1990 period, we examine it in great detail. For the whole period, and for the post-1990 period where the momentum profit is strongest, our evidence is generally consistent with the studies on common stocks other than REITs. The only striking exception is that we find that momentum is stronger for the larger REITs rather than for the smaller REITs. In our multiple regressions that include the characteristics as well as interactions between past returns and firm characteristics, the turnover–momentum interaction effect provides the most significant results. More specifically, momentum effects are stronger for more liquid REITs.     

Inter‐industry Wage Differences and Individual Heterogeneity*

Two well‐established findings are apparent in the analyses of individual wage determination: cross‐section wage equations can account for less than half of the variance in earnings and there are large and persistent inter‐industry wage differentials. We explore these two empirical regularities using longitudinal data from the British Household Panel Survey (BHPS). We show that around 90% of the variation in earnings can be explained by observed and unobserved individual characteristics. However, small – but statistically significant – industry wage premia do remain, and there is also a role for a rich set of job and workplace controls.
