Facilitators and barriers to pregnant women’s participation in research: A systematic review

Background

Although there is consensus among many that exclusion of pregnant women from clinical research should be justified, there is uncertainty as to whether and why pregnant women themselves would be willing to participate even if they were found to be eligible. The objective was to identify the reasons why pregnant women participate in clinical research and thereby to distinguish between facilitators and barriers.

Measuring Well-being Across Europe: Description of the ESS Well-being Module and Preliminary Findings

It has become customary to judge the success of a society through the use of objective indicators, predominantly economic and social ones. Yet in most developed nations, increases in income, education and health have arguably not produced comparable increases in happiness or life satisfaction. While much has been learned from the introduction of subjective measures of global happiness or life satisfaction into surveys, significant recent progress in the development of high-quality subjective measures of personal and social well-being has not been fully exploited. This article describes the development of a set of well-being indicators which were included in Round 3 of the European Social Survey. This Well-being Module seeks to evaluate the success of European countries in promoting the personal and social well-being of their citizens. In addition to providing a better understanding of domain-specific measures, such as those relating to family, work and income, the design of the Well-being Module recognises that advancement in the field requires us to look beyond measures which focus on how people feel (happiness, pleasure, satisfaction) to measures which are more concerned with how well they function. This also shifts the emphasis from relatively transient states of well-being to measures of more sustainable well-being. The ESS Well-being Module represents one of the first systematic attempts to create a set of policy-relevant national well-being accounts.

Generationenbeziehungen

The different persons involved in social relationships perceive the same relationship quite differently. This assumption, called the ?intergenerational stake hypothesis“ in intergenerational relations research, is tested by an investigation of emotional closeness, perception of conflicts, and the exchange of support among familial generations. In these data, parents tend to perceive greater emotional closeness and less conflict than their children. In the perception of exchanges of support, however, both parents and children impute greater weight to support received than to support given. Given that some differences among generations are observable, the fact that both parties of the same relationship are rarely captured in survey data presents a potential problem for empirical social research. What kinds of skewing or bias can be expected when not all perspectives are accounted for? The constructed models indicate that the bias so produced is marginal, thus the current practice of surveying only one side of the relationship would appear to be adequate.     

A nuclear medicine patient/instrument scheduling model

The problem of scheduling patients and clinical instruments for each physician-requested Nuclear Medicine study, in a clinical environment, is resolved through the development of a computerized heuristic model. The study schedule was determined by minimizing such factors as elapsed instrument time, instrument idle time, and maximizing instrument utilization. The heuristic scheduling procedure was developed and evaluated for scheduling thirteen different Nuclear Medicine study types on a daily basis. The analysis showed that this heuristic can be utilized to provide a good basic schedule for use in Clinical Nuclear Medicine.     

Symbolic Interaction and Transformation of Class Structure: The Case of China

So far, research on the shaping and change of class stratification has remained a territory for Marxist and Weberian scholars and, to a lesser degree, for functionalist scholars. The outcome in the explanatory domain is the production of a tremendous amount of knowledge concerning the relevance of structural conditions and power. Unfortunately, however, the significance of meaning as an independent explanatory variable has been neglected. This article attempts to tackle the neglected dimension empirically, using a revised macro‐level symbolic interactionist approach. Its objectives are twofold: to reveal the crucial impact of meaning on the radical change of class structure in the context of China's economic reform and to demonstrate the potential of symbolic interactionism for studying macro‐level sociological phenomena such as class stratification.     

The Folk Theorem for Games with Private Almost‐Perfect Monitoring

We prove the folk theorem for discounted repeated games under private, almost‐perfect monitoring. Our result covers all finite, n‐player games that satisfy the usual full‐dimensionality condition. Mixed strategies are allowed in determining the individually rational payoffs. We assume no cheap‐talk communication between players and no public randomization device.     

Modeling Risk‐Related Knowledge in Tunneling Projects

Knowledge on failure events and their associated factors, gained from past construction projects, is regarded as potentially extremely useful in risk management. However, a number of circumstances are constraining its wider use. Such knowledge is usually scarce, seldom documented, and even unavailable when it is required. Further, there exists a lack of proven methods to integrate and analyze it in a cost‐effective way. This article addresses possible options to overcome these difficulties. Focusing on limited but critical potential failure events, the article demonstrates how knowledge on a number of important potential failure events in tunnel works can be integrated. The problem of unavailable or incomplete information was addressed by gathering judgments from a group of experts. The elicited expert knowledge consisted of failure scenarios and associated probabilistic information. This information was integrated using Bayesian belief‐networks‐based models that were first customized in order to deal with the expected divergence in judgments caused by epistemic uncertainty of risks. The work described in the article shows that the developed models that integrate risk‐related knowledge provide guidance as to the use of specific remedial measures.     

Re-distributed manufacturing and the food-water-energy nexus: opportunities and challenges

Abstract

Addressing the intersection of two important emerging research areas, re-distributed manufacturing (RDM) and the food-energy-water (FEW) nexus, this work combines insights from engineering, business and policy perspectives and explores opportunities and challenges towards a more localized and sustainable food system. Analysis centred on two specific food products, namely bread and tomato paste reveals that the feasibility and potential of RDM vary with the type of food product and the supply chain (SC) components. Physically, energy efficiency, water consumption and reduction of waste and carbon footprint may be affected by scale and location of production activities and potentials of industrial symbiosis. From the business perspective, novel products, new markets and new business models are expected in order for food RDM to penetrate within the established food industry. Studies on policies, through the lens of public procurement, call for solid evidence of envisioned environmental, social and economic benefits of a more localized food system. An initial integrated framework is proposed for understanding and assessing food RDM and the FEW nexus.
