Closing the circle: participant views of a 360 degree feedback programme

The use of 360 degree feedback is becoming increasingly commonplace in organisations. It is claimed that this programme offers a more rounded diagnosis of development needs resulting in more effective development plans for individuals and more strategically focused investment in training for the organisation as a whole. These claims are tested in a qualitative and quantitative field study of participants in a 360 degree programme for middle and senior managers at a UK university. Some elements of the programme are found to work better than others, but participants rate their experience of almost all aspects of training and development as significantly better than a matched sample of non‐participants, and this leads to more positive global evaluations of the employer. The implications for the use of 360 degree programmes are discussed with regard to the critical HRM literature.

Knowledge-sharing rewards in enterprise social networks: effects of learner types and impact of digitisation

ABSTRACT

The era of total digitisation demands companies to seek innovative approaches in managing digital assets. This paper presents and studies an analytical model of an enterprise social network (ESN) employed by organisations in facilitating knowledge sharing and learning. Exploring the design of reward systems that motivate workers to share knowledge, we focus on how the dominant type of learners (avid or impressionable), the network structure of the ESN, and digitisation affect the reward systems. This research provides valuable insights for practitioners to implement appropriate reward systems to promote knowledge sharing and learning in ESNs.     

Fitting the mould: the role of employer perceptions in immigrant recruitment decision-making

Human capital theory presumes that skill-accredited immigrant professionals can access positions in the labour market to match their skills and qualifications. It implies that employers have little power to influence the labour market outcomes of immigrant professionals. Using social identity theory, we examine the influence of similarity effect in recruitment decision-making involving immigrant information technology (IT) professionals in New South Wales, Australia. We assess how decision makers (N = 331) hiring IT professionals need to associate and identify with people that resemble themselves in some way more than those that do not, can influence their perception of the immigrant candidate's fit into their organisation. Particularly, we examine how the level of exposure to diversity, the decision maker's origin and the diversity of clientele can moderate the assessment of the candidate's fit to the organisation. We also assess how attire, name, accent and any overtly expressed religious affiliations influence employer perceptions. The findings indicate decision makers with lower levels of exposure to diversity or working in organisations with mostly Anglo clients tend to be more concerned of the fit regarding the Indians, South-east Asians and the Chinese. They were also more likely to be negatively influenced by the non-Anglo personal attributes.     

On becoming a sociomaterial researcher: Exploring epistemological practices grounded in a relational,performative ontology

What is the role of the researcher in a world that is continuously enacted and reconfigured in sociomaterial practices, a world in which subject and object, structure and agency, body and mind, knower and known, are assumed to be ontologically inseparable? In this article, I explore this question by drawing on my own experiences of reconsidering essentialist and representationalist assumptions, and becoming a sociomaterial researcher. My exploration draws on my experiences of conducting a qualitative longitudinal case study at the Swedish Migration Board. Specifically, I show what it can mean to ‘invite materiality’ into interviews, examine the conditions of possibility to become in certain ways by tracing the genealogy of practices, and engage with data relationally rather than categorically. By accounting for my experience of working through these practices, I aim to develop and articulate an understanding of what the ontological position underlying a sociomaterial approach implies for epistemology, and of how we can act (or, rather, intra-act) more creatively and responsibly as sociomaterial researchers. Moreover, I highlight differences in the kinds of knowledge that a sociomaterial approach grounded in relational and performative onto-epistemologies, as opposed to a socio-material approach, grounded in critical realism, produce about the unfolding of organizational practices—specifically, the practices unfolding in the reception area of the Swedish Migration Board. The paper contributes to the current debate on sociomaterial approaches, and in particular to the development of practices available to draw upon for researchers taking a sociomaterial approach.     

Fitting Regional Income Distributions in the European Union*

Cross‐sectional distribution of per capita (log) GDP across the European Union regions from 1977 to 1996 is analysed. Kernel density estimates reveal a multimodal structure of the distribution during the 1970s and early 1980s, and a tendency towards unimodality since the mid‐1980s. The distribution is further analysed by a mixture of normal densities. A two well‐separated component mixture fits the distributions in the 1970s and early 1980s. These two clusters tend to converge, supporting the idea of a process of catching up. In the mid‐1990s, a small group of very rich regions is generated by a separated component.

GPS在桥梁与隧道工程中拟合模型实例分析

本文结合工程实例数据对比分析两种方法,通过拟合结果可知:当纵横向跨度比较小、地形变化比较平缓时,对于两种拟合方法来说,通常情况下都可以达到三等水准精度;但是三次样条拟合法不适应测区较大、地形条件变化比较复杂的情况,对于移动曲面拟合法来说,通常能够达到等外水准要求,进而在一定程度上满足桥梁工程、隧道工程的施工需要。     

Fitting circles to scattered data: parameter estimates have no moments

We study a nonlinear regression problem of fitting a circle (or a circular arc) to scattered data. We prove that under any standard assumptions on the statistical distribution of errors that are commonly adopted in the literature, the orthogonal regression estimators of the circle center and radius have infinite (absolute) moments. We also discuss methodological implications of this fact.

Solving Multicollinearity in the Process of Fitting Regression Model Using the Nested Estimate Procedure

In the practical cases, we are usually faced with the more difficult problem of multicollinearity in our fitted regression model. Multicollinearity will arise when there are approximate linear relationships between two or more independent variables. It may cause some serious problems in validation, interpretation, and analysis of the model, such as unstable estimates, unreasonable sing, high-standard errors, and so on. Although there are some methods to solve or avoid this problem, we will propose another alternative from the practical view in this paper, called nested estimate procedure. The first half of the paper explains the concept and process of this procedure, and the second half provides two examples to illustrate this procedure’s suitability and reliability.     

Fitting and Forecasting Sovereign Defaults using Multiple Risk Signals

In this article, we try to realize the best compromise between in‐sample goodness of fit and out‐of‐sample predictability of sovereign defaults. To do this, we use a new regression‐tree based approach that signals impending sovereign debt crises whenever pre‐selected indicators exceed specific thresholds. Using data from emerging markets and Greece, Ireland, Portugal and Spain (GIPS) over the period 1975–2010, we show that our model significantly outperforms existing competing approaches (logit, stepwise logit, noise‐to‐signal ratio and regression trees), while balancing in‐ and out‐of‐sample performance. Our results indicate that illiquidity (high short‐term debt to reserves) and default history, together with real GDP growth and US interest rates, are the main determinants of both emerging market country defaults and the recent European sovereign debt crisis.
