Bayesian factor analysis for spatially correlated data: application to cancer incidence data in Scotland

A hierarchical Bayesian factor model for multivariate spatially correlated data is proposed. Multiple cancer incidence data in Scotland are jointly analyzed, looking for common components, able to detect etiological factors of diseases hidden behind the data. The proposed method searches factor scores incorporating a dependence within observations due to a geographical structure. The great flexibility of the Bayesian approach allows the inclusion of prior opinions about adjacent regions having highly correlated observable and latent variables. The proposed model is an extension of a model proposed by Rowe (2003a) and starts from the introduction of separable covariance matrix for the observations. A Gibbs sampling algorithm is implemented to sample from the posterior distributions.     

Applying a longitudinal interpretive multi-case research method to study the employee impact of operations management systems in a micro firm setting

Abstract

While many operations management journals are now publishing interpretive studies, there is still a need for more material on how to carry out such work under the interpretive gestalt. By offering a research account of a longitudinal interpretive multi-case study, this paper seeks to contribute to the literary gap in ‘how to do it [interpretive research]’. The purpose of this paper is to document a longitudinal operations management study in three micro-firms, where the catalyst for this study is the implementation of an electronic operations management system in each case. The paper chronicles the authors’ experience in a four-year multi-case study, and as such provides insight into design, development and execution of longitudinal interpretive operations management research, and the building of a theoretical model. While blueprints are not the purpose of such reflections, they can provide insight and advice to researchers, which is the underlying goal of this paper.     

Developing management capability within a horizontal supply chain in performance measurement deployment and evolution: a Dynamic Capabilities and Goal Theory perspective

Abstract

Complex collaboration in rapidly changing business environments create challenges for management capability in Utility Horizontal Supply Chains (UHSCs) involving the deploying and evolving of performance measures. The aim of the study is twofold. First, there is a need to explore how management capability can be developed and used to deploy and evolve Performance Measurement (PM), both across a UHSC and within its constituent organisations, drawing upon a theoretical nexus of Dynamic Capability (DC) theory and complementary Goal Theory. Second, to make a contribution to knowledge by empirically building theory using these constructs to show the management motivations and behaviours within PM-based DCs. The methodology uses an interpretive theory building, multiple case-based approach (n = 3) as part of a USHC. The data collection methods include, interviews (n = 54), focus groups (n = 10), document analysis and participant observation (reflective learning logs) over a five-year period giving longitudinal data. The empirical findings lead to the development of a conceptual framework showing that management capabilities in driving PM deployment and evolution can be represented as multilevel renewal and incremental Dynamic Capabilities, which can be further understood in terms of motivation and behaviour by Goal-Theoretic constructs. In addition, three interrelated cross-cutting themes of management capabilities in consensus building, goal setting and resource change were identified. These management capabilities require carefully planned development and nurturing within the UHSC.     

Dignity in dementia: Person-centered care in community

Drawing on Kitwood's [Ageing Soc. 13 (1993) 51] theory of person-centered care and the interpersonal process of caregiving, this article offers an alternative to the image of the family caregiver as victim through an exploration of the lived experience of caring for a person with dementia in community. Extending care beyond coping, the act of giving care is promoted as a worthy activity and reciprocal social opportunity. Three nonfamily caregiver “portraits” are offered in an arts-informed representational form. The relational processes of caregiving are explored from the vantage point of personal experience and theoretical knowledge. Dignity emerges as the resonant quality, essential value, and guiding principle in an ethic of dementia care. Implications about the direction of research about care and caregiving and research accessibility and usefulness are explored.     

Maternal Silence

Interpellation is not only a function of public life. It is also at home. Here Maura Sheehy works with Melissa, a young mother, who, just like her analyst, struggles with the multiple interpellations of motherhood. Abjected as well as idealized, motherhood produces both exaltation and utter confused misery for both. As the treatment proceeds, we witness analyst's and patient's common search for intelligibility, a parallel process in which the analyst finds/sees how both her patient and she locate themselves in and wrestle with discourse, an engagement that effects change in both.     

Virginity Loss Narratives in “Teen Drama” Television Programs

A number of studies have described different preference patterns typically found for men and women when choosing romantic mates. These vary according to the involvement level expected in the relationship. Despite the number of investigations on the topic, one must be careful not to generalize because most studies use samples composed of North American university undergraduates. This study sought to determine if the preference patterns typically found in other countries also occur among Brazilian undergraduates. The importance of characteristics and modifications in preference patterns under gradually restrictive conditions was also investigated. In general, the results obtained suggest that the preferences found in a number of countries also occur in Brazil. In short-term relationships, men prioritize physical attributes, whereas personal traits gain importance when involvement increases. Women in short-term relationships value physical and personal traits, whereas in the long term, they emphasize personal characteristics and their mate's desire to acquire resources. Resource-related traits were less important than the other traits, and were more important for women than for men.     

The role of Lean at the interface with between operations management and applied services within a large aerospace organisation: a boundary spanning perspective

Increased complexity in large design and manufacturing organisations requires improvements at the operations management (OM)–applied service (AS) interface areas to improve project effectiveness. The aim of this paper is explore the role of Lean in improving the longitudinal efficiency of the OM–AS interface within a large aerospace organisation using Lean principles and boundary spanning theory. The methodology was an exploratory longitudinal case approach including exploratory interviews (n = 21), focus groups (n = 2), facilitated action-research workshops (n = 2) and two trials or experiments using longitudinal data involving both OM and AS personnel working at the interface. The findings draw upon Lean principles and boundary spanning theory to guide and interpret the findings. It was found that misinterpretation, and forced implementation, of OM-based Lean terminology and practice in the OM–AS interface space led to delays and misplaced resources. Rather both OM and AS staff were challenged to develop a cross boundary understanding of Lean-based boundary (knowledge) objects in interpreting OM requests. The longitudinal findings from the experiments showed that the development of Lean Performance measurements and lean Value Stream constructs was more successful when these Lean constructs were treated as boundary (knowledge) objects requiring transformation over time to orchestrate improved effectiveness and in leading to consistent terminology and understanding between the OM–AS boundary spanning team.     

Methods for Measuring Mechanisms of Contention

A substantial intellectual movement has been growing in the social sciences around the adoption of mechanism- and process-based explanations as complements to variable-based explanations, or even as substitutes for them. But once we have recognized the validity and dignity of studying mechanisms and processes, what is the next step? Recently, both political scientists’ and sociologists’ discussions have begun to turn away from correlation to mechanism-based approaches to causation. But there is still a widespread assumption that mechanisms are unobservable. We maintain that ways can be developed to observe the presence or absence of mechanisms either directly or indirectly. In this paper, by way of example, we put forward four methods—two direct and two indirect—for measuring mechanisms of contention.     

Vital Connections: Using Literature to Illustrate Social Work Issues

Abstract

This paper introduces a four stage teaching model which encourages students to use fiction as a source of mental imagery and insight into social work issues. Teachers can use the stages flexibly for different courses and levels of student expertise. The model has been developed by the authors during three years of formally implementing it in a range of undergraduate and graduate syllabi. The authors present this approach following detailed observation of the quality of written assignments, classroom interaction and student feedback. This is an exciting way of teaching traditional courses which generates a lively atmosphere for learning.

The Dutch East and West India Companies established colonies in the Caribbean, Brazil and at the Cape of Good Hope. The resulting townscapes can be read as artefacts of domination ‐ attempts to stamp order on the chaos of newly‐colonized lands. But at the same time, such built forms incorporated knowledge of the “low‐other” ‐ the underclasses in highly hierarchical colonial worlds. As a result, the experience of resistance (rarely directly visible in such public constructions as street grids and building fagades) was incorporated into the symbolic language of dominance, setting up a dialectical relationship between the High and the Low.
