Heterogeneity and study size in random-effects meta-analysis

It is well known that heterogeneity between studies in a meta-analysis can be either caused by diversity, for example, variations in populations and interventions, or caused by bias, that is, variations in design quality and conduct of the studies. Heterogeneity that is due to bias is difficult to deal with. On the other hand, heterogeneity that is due to diversity is taken into account by a standard random-effects model. However, such a model generally assumes that heterogeneity does not vary according to study-level variables such as the size of the studies in the meta-analysis and the type of study design used. This paper develops models that allow for this type of variation in heterogeneity and discusses the properties of the resulting methods. The models are fitted using the maximum-likelihood method and by modifying the Paule–Mandel method. Furthermore, a real-world argument is given to support the assumption that the inter-study variance is inversely proportional to study size. Under this assumption, the corresponding random-effects method is shown to be connected with standard fixed-effect meta-analysis in a way that may well appeal to many clinicians. The models and methods that are proposed are applied to data from two large systematic reviews.     

An Adaptive Test for the Two-Sample Location Problem Based on U-Statistics

For the two-sample location problem with continuous data we consider a general class of tests, all members of it are based on U-statistics. The asymptotic efficacies are investigated in detail. We construct an adaptive test where all statistics involved are suitably chosen U-statistics. It is shown that the proposed adaptive test has good asymptotic and finite sample power properties.     

Improving patients’ satisfaction in a mobile hospital using Lean Six Sigma – a design-thinking intervention

Abstract

Lean Six Sigma (LSS) that offers a unique integration of Lean and Six Sigma has been accepted globally across services sectors. Previous studies that examined the application of LSS in healthcare were steered in traditional hospital settings. Apparently, there are no studies that highlight the application of LSS in mobile hospitals, an emerging trend in the healthcare sector. The aim of this article is to explore the applicability of LSS in a mobile hospital. The authors present a case study of improving patients’ satisfaction in a mobile hospital, through reducing turnaround time. Design-thinking intervention to LSS helped resolve a real-time problem using Define-Measure-Analyze-Design-Verify roadmap. This article contributes to the ‘healthcare quality” body of knowledge and is novel as it is the first of its kind of LSS application in a mobile hospital underpinning Design thinking. This study is unique as it demonstrates academia–industry collaboration in solving an organizational problem.     

You don’t forget where you come from: linking formation and operations in publicly funded innovation networks

Abstract

Publicly funded innovation networks (PFINs) are an increasing form of organizing joint innovation activities. Yet, little is known about this form of organization which mixes characteristics of centralized and de-centralized innovation networks. This research investigates how processes of network formation affect its operation in PFINs as a hybrid form between centralized and de-centralized networks. Presenting rich data from a PFIN in the Scandinavian maritime industry, the findings show three patterns linking network formation and operation. The first pattern – well-aligned centralized and de-centralized approaches – in network formation resulted in well-functioning network operation. The second pattern – misalignment between centralized and de-centralized approaches in network formation resulted in stagnating innovation activities during network operation. The third pattern – a pre-dominant de-centralized approach during network formation resulted in unconnected sub-activities during network operation. This research contributes by showing the importance of utilizing both centralized and de-centralized approaches and aligning them to enable well-functioning network formation and operation.     

Afghan families and health professionals’ access to health information during and after pregnancy

BackgroundHaving a baby in a new country can be challenging, especially if unable to communicate in a preferred language. The aim of this paper is to explore the provision of health information for Afghan women and men during pregnancy, childbirth and the first year after birth in Melbourne, Australia.MethodsCommunity engagement underpinned the study design. Qualitative study with bicultural researchers conducting semi-structured interviews. Interviews and focus groups were also conducted with health professionals.ResultsSixteen Afghan women and 14 Afghan men with a baby aged 4–12 months participated. Thirty four health professionals also participated. Verbal information provided by a health professional with an interpreter was the most common way in which information was exchanged, and was generally viewed favourably by Afghan women and men. Families had limited access to an interpreter during labour and some families reported difficulty accessing an interpreter fluent in their dialect. Availability of translated information was inconsistent and health professionals occasionally used pictures to support explanations. Women and men were unsure of the role of health professionals in providing information about issues other than pregnancy and infant wellbeing.ConclusionBoth individual and health system issues hinder and enable the availability and use of information. Consistent, understandable and ‘actionable’ information is required to meet the needs of diverse families. Health professionals need to be supported with adequate alternatives to written information and access to appropriate interpreters. Inconsistent provision of information is likely to contribute to low health literacy and poor maternal and child health outcomes.     

Are labour inspections effective when labour regulations vary according to the size of the firm? Evidence from Peru

This article analyses the impact of enforcement of four labour standards (pension system enrolment, minimum wage, maximum weekly working hours and written employment contract) on compliance in Peru, where labour regulations and penalties vary according to firm size. The author uses household survey data to analyse a factor not previously studied – adjustment by firms through downsizing to benefit from lower fines and less stringent regulations. The empirical findings indicate that enforcement efforts have little effect on either the degree of compliance or the size of firms.     

How do researchers perceive research misbehaviors? A transcultural case study of Chinese and Flemish researchers

China has achieved a dramatic development in scientific research over the last few decades. However, just like many other countries, it has also seen a surge of scientific misconducts. With its expansion of international publications, retractions due to suspected research misconduct are also on the rise. A transcultural case study was conducted by investigating the perception of research misbehaviors by Chinese researchers compared to their Belgian Flemish colleagues. The study was designed to find out variation in research practices in different countries and to see how research was shaped and influenced by cultural contexts. An online questionnaire was sent to 3,236 researchers by e-mails and it received a response rate of 13.09%. They were asked to score 32 research misbehaviors on a 5-point scale. The findings suggested that compared to Flemish respondents, the Chinese had a significantly higher acceptance toward most research misbehaviors. To be more specific, the Chinese respondents felt less unacceptable toward behaviors violating such values as honesty, fairness, and verifiability than the Flemish, while their perceptions of behaviors that violated such values as responsibility, objectivity, and truth were not different compared to the Flemish. This case study implies that the Chinese research community is in an urgent need of training in responsible conduct of research and strong as well as sound guidelines for responsible research practices in place.
