Offshore but on track? Hypermobile and hyperflexible working lives

In the spring 2011, and again during summer 2012, the small coastal town of Hirtshals (approx. 6000 inhabitants) on the north-western shore of Denmark was home to two spectacular symbols of the success of an emergent offshore sector in the region, namely the upgrading and overhauling of two gigantic oil rigs. Providing temporary work for an estimated 800 persons who literally worked day and night for the 100 days each rig was at dock, these events affected the entire community. The paper presents evidence from seven biographical interviews with local men whose working lives were directly or indirectly affected by these events. As the interviews illuminate, respondents are often extremely mobile and flexible in terms of their jobs, in some cases ‘bungy jumping’ through working life in an apparent effort to retain local ties while pursuing global opportunities. The paper contributes to qualifying more general sociological discussions about the push for increased mobility and flexibility in a presumably increasingly globalising labour market reality. Ultimately, it seems that the multiple ways in which Hirtshals is marked as marginal – in terms of geography, socio-economic profile and discourse – may serve to normalise demands for flexibility and mobility, at least amongst parts of the local working population.     

When is Condorcet's Jury Theorem valid?

Existing proofs of Condorcet's Jury Theorem formulate only sufficient conditions for its validity. This paper provides necessary and sufficient conditions for Condorcet's Jury Theorem. The framework of the analysis is the case of heterogeneous decisional competence, but the independence assumption is maintained. Received: 23 January 1997/Accepted: 8 March 1997     

Couple Forgiveness and its Moderating Role in the Intergenerational Transmission of Veterans’ Posttraumatic Stress Symptoms

This study examined the moderating effect couple forgiveness (as perceived by the wives/mothers) may have on the intergenerational transmission of posttraumatic stress symptoms (PTSS) among families of combat veterans and former prisoners of war (ex‐POWs). The sample included 123 (79 ex‐POWs and 44 control combatants) Israeli father–mother–adult offspring triads. Self‐report measures were administered at 2008 to veterans, at 2010–2011 to wives, and at 2013–2014 to offspring. The findings indicated that ex‐POWs’ PTSS were positively related to their offspring's PTSS, while couple forgiveness buffered this effect, particularly, and detrimentally, when couple forgiveness was low. These findings imply that apprehending the quality of the forgiving atmosphere within the marital relationship may be important for understanding the apparatus of intergenerational transmissions of trauma.     

A General Approach To Nonparametric Histogram Estimation

We note that some classical functional estimation problems may be reduced to a general unique framework and study an estimator within this general framework that reduces to the classical histogram type estimators in various examples presented. The convergence in probability and the almost complete convergence of this general estimator are studied obtaining convergence conditions which reduce to the classical conditions in each case. Finally, this general framework provides conditions for the convergence of the finite dimensional distributions of the associated empirical process.     

Local linear regression with adaptive orthogonal fitting for the wind power application

Short-term forecasting of wind generation requires a model of the function for the conversion of meteorological variables (mainly wind speed) to power production. Such a power curve is nonlinear and bounded, in addition to being nonstationary. Local linear regression is an appealing nonparametric approach for power curve estimation, for which the model coefficients can be tracked with recursive Least Squares (LS) methods. This may lead to an inaccurate estimate of the true power curve, owing to the assumption that a noise component is present on the response variable axis only. Therefore, this assumption is relaxed here, by describing a local linear regression with orthogonal fit. Local linear coefficients are defined as those which minimize a weighted Total Least Squares (TLS) criterion. An adaptive estimation method is introduced in order to accommodate nonstationarity. This has the additional benefit of lowering the computational costs of updating local coefficients every time new observations become available. The estimation method is based on tracking the left-most eigenvector of the augmented covariance matrix. A robustification of the estimation method is also proposed. Simulations on semi-artificial datasets (for which the true power curve is available) underline the properties of the proposed regression and related estimation methods. An important result is the significantly higher ability of local polynomial regression with orthogonal fit to accurately approximate the target regression, even though it may hardly be visible when calculating error criteria against corrupted data.     

Boundary and Bias Correction in Kernel Hazard Estimation

A new class of local linear hazard estimators based on weighted least square kernel estimation is considered. The class includes the kernel hazard estimator of Ramlau-Hansen (1983), which has the same boundary correction property as the local linear regression estimator (see Fan & Gijbels, 1996). It is shown that all the local linear estimators in the class have the same pointwise asymptotic properties. We derive the multiplicative bias correction of the local linear estimator. In addition we propose a new bias correction technique based on bootstrap estimation of additive bias. This latter method has excellent theoretical properties. Based on an extensive simulation study where we compare the performance of competing estimators, we also recommend the use of the additive bias correction in applied work.     

Attachment insecurities and under-commitment in distressed couples: The role of positive and negative partner behaviors

Research has rarely considered intermediate variables in the association between attachment insecurities and relationship commitment. Based on attachment theory and Rusbult's Investment Model, we tested whether positive and negative partner behaviors explain this association in 91 distressed couples undergoing therapy. Path analyses based on the Actor–Partner Interdependence Model revealed that individuals with attachment avoidance reported perceiving fewer positive behaviors from their partner, which was associated with their own higher under-commitment. Partners of individuals with avoidance also reported perceiving fewer positive partner behaviors, which was in turn associated with their own higher under-commitment. Partners of individuals with attachment anxiety perceived more positive behaviors from their partner, which was associated to their own lower under-commitment. Perceived negative partner behaviors were only directly associated with higher under-commitment. These findings imply that perceived positive partner behaviors may be a key aspect to target in relationship therapy in couples who present with high attachment insecurities.     

Challenges and boundaries in implementing social return on investment: An inquiry into its situational appropriateness

Nonprofit organizations (NPOs) and social enterprises are increasingly under pressure to justify their use of resources and report their impact on society. Frameworks that monetize social value such as social return on investment (SROI) have emerged as a response. The existing literature highlights many benefits and technical challenges of SROI, but largely ignores strategic and organizational learning aspects. This paper explores the use of SROI in an NPO conducting cultural heritage preservation. By analyzing the challenges managers face in agreeing on a reliable (“correct”) computation of SROI and in assessing the validity and relevance (“appropriateness”) of SROI, we seek to understand the challenges and boundaries of SROI. Challenges with a reliable computation of SROI are identifying stakeholders, the choice of proxies, the time horizons, and deadweight factors. Challenges with an appropriate SROI calculation are comparability, subjectivity, legitimacy, and resource utility. We argue that SROI calculations might not be reliable or appropriate in organizations with fuzzy purposes, broad value creation goals, broad target groups, very individual or subjective proxies, strongly lagged outcomes, complex or unobservable causality, and with lack of legitimacy among stakeholders. Organizations should not trustingly adopt SROI without being aware of these limitations.     

Systematically collected information at encounters with HIV-positive students: A review of 10 years of electronic medical records

Abstract

Objective: The objective of this study was to examine clinical and epidemiological information collected by Student Health Center (SHC) providers on HIV-positive students, and benchmark this information against Infectious Disease Society of America guidelines. Participants: Students who utilized the SHC and had an ICD-9 code indicating positive HIV status between 2005 and 2015 (3?=?7). Methods: In June 2016, we accessed the free-form provider notes of the SHC’s electronic medical records to identify specific, recorded epidemiological and clinical information. Results: Seven unique students sought care at the SHC during the study period. Current sexual risk taking and other known behavioral risk factors were absent from all records, along with CD4 count and viral load. ART status was only available for one patient, and he was not on ART. The information collected failed to meet IDSA benchmarks. Conclusion: Clinically- and epidemiologically-relevant information is not systematically collected from HIV-positive students at SHCs.     

What Determines the Substantive Influence of Public Participation? An Investigation of Planners’ Views on Conditions for Participatory Practices in Denmark

Conditions that enable successful public participation have received increased attention in research and practice. This paper contributes with an empirical study of the conditions that determine the substantive influence of public participation processes. We explore a list of conditions in a Danish context through a survey of practitioners’ perceptions of practice and through interviews with practitioners. The findings support the growing criticism of the widespread notion that the choice of methods is a fundamental determinant of the success of public participation. The findings lead us to propose a more prominent role of contextual conditions in practice.
