Based on the findings of substantial research, Western professionals today perceive corporal punishment as a threat to child well-being. They also view it as a violation of children's rights. Nonetheless, many minority groups in Western societies still consider it to be a legitimate child-rearing practice. In response to this gap, this article presents qualitative findings from an exploratory context-informed study of Ultra-Orthodox Jewish fathers in Israel, regarding their perceptions and ascribed meanings of corporal punishment. Our exploration was guided by the following research question: What are the constructions, perceptions, beliefs, and meanings associated with corporal punishment among Ultra-Orthodox Litvak fathers in Israel? The thematic analysis of 15 in-depth semi-structured interviews yielded two central themes. The first is the view of corporal punishment as an educational tool with legitimacy based on religious sources and emotion-focused rationales. The second theme deals with different limitations on and guidelines regarding this legitimacy. Children were struck as a result of behavior that parents experienced as extreme, and striking the child in response to religious wrongdoing was viewed as problematic. The fathers interviewed stressed the need to suit the punishment to the child, in terms of the intensity of the blow, frequency, and the age of the child. The fathers also emphasized the importance of the child's subjective experience being one of education as opposed to humiliation. Implications from these findings illustrate the gaps between the Ultra-Orthodox community and professionals who espouse the Western view that prohibits corporal punishment; at the same time, they portray the fathers as expressing an intricate approach toward corporal punishment, with conditions and limitations, as opposed to absolute approval. This article advocates a context-informed approach toward dealing with corporal punishment in minority groups that legitimize the practice. Adopting such an approach may contribute to better cooperation between professionals and their clients from minority groups, and advance child well-being. [ABSTRACT FROM AUTHOR]

Opioid is the second most prevalent illicit drug worldwide, whose consumption is very high in Iran, due to Iran's geographical proximity to producing countries. Methadone maintenance therapy is one of the most prevalent and accepted methods of substance abuse treatment. Nevertheless, cognitive disorders have been reported as one of its complications. This study was conducted to evaluate cognitive impairment in methadone maintenance patients (MMPs) and to compare it with abstinent opioid users (AOUs). This cross-sectional analytical study was performed on 25 MMPs and 25 AOUs. Samples were selected through convenience sampling method whereby a self-made questionnaire was distributed among them to assess demographic information, clinical variables such as methadone and opioid use history, underlying disease and medication history, as well as 13-item Beck depression inventory. Then, they were interviewed using the Montreal Cognitive Assessment (MoCA) questionnaire. Significant differences were found in MoCA questionnaire total scores (p = 0.018) and orientation to time and place dimension (p = 0.008) between the two groups, with the mean scores being higher in AOU group. Duration of opioid use was the only factor influencing cognitive assessment score in both Groups. (p = 0.029) We suggest monitoring and assessing cognition function in patients receiving methadone especially for those with a long history of opioid use. [ABSTRACT FROM AUTHOR]

Scientific research is the pillar of science and therefore the aim of every university, as well as the current university policies contemplate the development of an integral university committed to society, which is why within the quality standards University Social Responsibility (USR) is contemplated. In the research, we analysed the differences in the impact of social responsibility on the development of scientific research in Peruvian universities. Although there are several models and theories, as well as instruments to evaluate USR, the study used the questionnaires of [1]Baca et al (2017). The sample obtained is 108 theses corresponding to the periods 2017 to 2020, the design is non-experimental. The study concludes that there are significant differences between the two universities in terms of linking research with USR, and this may be due to factors related to unconnected policies between faculties.

Purpose: To ascertain the diffusion and influence of Savolainen's ELIS model and its use as a theoretical and/or methodological basis for research. Design/methodology/approach: A context citation analysis was made of the work where this researcher published his model. Analysis covered the year of publication, the type of work and the subject matter of the citing documents concerned. In-context citations were analysed for their frequency in each citing text, style, location and content cited. Findings: The ELIS model received 18.5 cites/year. 20.2 per cent of them corresponded to papers published in journals in other areas, mainly computer science. The average of cites per paper was 1.8; 64.5 percent of the citing works cited them only once. 60 per cent of the cites were considered essential. Only 13.7 per cent of these cites appear in theory or methods. 37 per cent of the citing documents contained no concept relating to the model. Research limitations/implications: The method used focuses on the most direct context of a cite (sentence or paragraph), but isolates it from the general context (full document, other documents by the author or their social capital). It has, however, allowed this research issue to be dealt with under laboratory conditions and revealed nuances hidden by the absolute number of cites. Originality/value: It has become evident that the dissemination and influence of the ELIS model are less than what the total number of cites indicates and that it has scarcely been incorporated into research design. Despite its popularity, it is not being validated and/or refuted by way of empirical data. [ABSTRACT FROM AUTHOR]

As a tribute to Ray Levitt's early computer science contributions, this paper presents the research methodology he and I in close collaboration with Barbara Hayes-Roth followed to develop the SightPlan system. This research methodology falls under the umbrella of what is known as "design science." Design science concerns itself with designing and making artefacts to fulfil a purpose, and then testing and validating that they indeed are fit-for-purpose. Design science does not belong in the category of physical science or of fundamental science; instead, it falls in the category of the sciences of the artificial. This paper describes the methodological steps pursued in design science and in parallel illustrates how these steps were instantiated and what artefacts were produced in the course of developing the SightPlan system, a blackboard expert system that lays out temporary facilities on construction sites. The aims of this paper are to recognise Ray's work as an advisor and researcher, reflect on and promote the use of design science in construction management and economics and thereby participate in the ongoing discussion on research methods in this journal, and illustrate to scholars in this field that research is an opportunistic endeavour.

This article discusses scientific alternatives to field systems analysis. According to the authors, researchers would benefit from a discussion of the philosophical foundations that various research traditions stem from, the inherent advantages and shortcomings of contemporary paradigmatic camps and the epistemological context of field systems analysis.

Objective: To investigate the effectiveness of a multi-component evidence-based education programme on disease modifying therapies in multiple sclerosis. Design: Controlled trial with two consecutive patient cohorts and a gap of two months between cohorts. Setting: Three neurological rehabilitation centres. Subjects: Patients with multiple sclerosis within rehabilitation. Interventions: Control group (CG) participants were recruited and received standard information. Two months later, intervention group (IG) participants were recruited and received a six-hour nurse-led interactive group education programme consisting of two parts and a comprehensive information brochure. Main measures: Primary endpoint was "informed choice", comprising of adequate risk knowledge in combination with congruency between attitude towards immunotherapy and actual immunotherapy uptake. Further outcomes comprised risk knowledge, decision autonomy, anxiety and depression, selfefficacy, and fatigue. Results: A total of 156 patients were included (IG=75, CG=81). The intervention led to significantly more participants with informed choice (IG: 47% vs. CG: 23%, P=0.004). The rate of persons with adequate risk knowledge was significantly higher in the IG two weeks after the intervention (IG: 54% vs. CG: 31%, P=0.007), but not after six months (IG: 48% vs. CG: 31%, P=0.058). No significant differences were shown for positive attitude towards disease modifying therapy (IG: 62% vs. CG: 71%,P=0.29) and for disease modifying therapy status after six months (IG: 61.5% vs CG: 68.6%, P=0.39). Also no differences were found for autonomy preferences and decisional conflict after six months. Conclusion: Delivering evidence-based information on multiple sclerosis disease modifying therapies within a rehabilitation setting led to a marked increase of informed choices.

Background: Presentation of confidence intervals alongside information about treatment effects can support informed treatment choices in people with multiple sclerosis. We aimed to develop and pilot-test different written patient information materials explaining confidence intervals in people with relapsing-remitting multiple sclerosis. Further, a questionnaire on comprehension of confidence intervals was developed and piloted.Methods: We developed different patient information versions aiming to explain confidence intervals. We used an illustrative example to test three different approaches: (1) short version, (2) "average weight" version and (3) "worm prophylaxis" version. Interviews were conducted using think-aloud and teach-back approaches to test feasibility and analysed using qualitative content analysis. To assess comprehension of confidence intervals, a six-item multiple choice questionnaire was developed and tested in a pilot randomised controlled trial using the online survey software UNIPARK. Here, the average weight version (intervention group) was tested against a standard patient information version on confidence intervals (control group). People with multiple sclerosis were invited to take part using existing mailing-lists of people with multiple sclerosis in Germany and were randomised using the UNIPARK algorithm. Participants were blinded towards group allocation. Primary endpoint was comprehension of confidence intervals, assessed with the six-item multiple choice questionnaire with six points representing perfect knowledge.Results: Feasibility of the patient information versions was tested with 16 people with multiple sclerosis. For the pilot randomised controlled trial, 64 people with multiple sclerosis were randomised (intervention group: n = 36; control group: n = 28). More questions were answered correctly in the intervention group compared to the control group (mean 4.8 vs 3.8, mean difference 1.1 (95 % CI 0.42-1.69), p = 0.002). The questionnaire's internal consistency was moderate (Cronbach's alpha = 0.56).Conclusions: The pilot-phase shows promising results concerning acceptability and feasibility. Pilot randomised controlled trial results indicate that the patient information is well understood and that knowledge gain on confidence intervals can be assessed with a set of six questions.Trial Registration: German Clinical Trials Register: DRKS00008561 .

Aim and objectives To examine how nurses collect and use cues from respiratory assessment to inform their decisions as they wean patients from ventilatory support. Background Prompt and accurate identification of the patient's ability to sustain reduction of ventilatory support has the potential to increase the likelihood of successful weaning. Nurses' information processing during the weaning from mechanical ventilation has not been well-described. Design A descriptive ethnographic study exploring critical care nurses' decision-making processes when weaning mechanically ventilated patients from ventilatory support in the real setting. Methods Novice and expert Scottish and Greek nurses from two tertiary intensive care units were observed in real practice of weaning mechanical ventilation and were invited to participate in reflective interviews near the end of their shift. Data were analysed thematically using concept maps based on information processing theory. Ethics approval and informed consent were obtained. Results Scottish and Greek critical care nurses acquired patient-centred objective physiological and subjective information from respiratory assessment and previous knowledge of the patient, which they clustered around seven concepts descriptive of the patient's ability to wean. Less experienced nurses required more encounters of cues to attain the concepts with certainty. Subjective criteria were intuitively derived from previous knowledge of patients' responses to changes of ventilatory support. All nurses used focusing decision-making strategies to select and group cues in order to categorise information with certainty and reduce the mental strain of the decision task. Conclusions Nurses used patient-centred information to make a judgment about the patients' ability to wean. Decision-making strategies that involve categorisation of patient-centred information can be taught in bespoke educational programmes for mechanical ventilation and weaning. Relevance to clinical practice Advanced clinical reasoning skills and accurate detection of cues in respiratory assessment by critical care nurses will ensure optimum patient management in weaning mechanical ventilation.

Breast cancer is the most frequent type of malignancy among women throughout Germany. The present analysis aimed to identify information needs and aspects of health literacy in women of working age newly diagnosed with breast cancer. PIAT is a prospective multicenter cohort study in which patients were asked about their information needs at 3 assessment points: postoperatively, after 10 weeks, and after 40 weeks. The present analysis includes data from 1,344 female patients after the first assessment point. In addition to descriptive analyses, logistic regression analyses were calculated. Results of the study show that, in addition to sociodemographic characteristics, the level of health literacy and the employment status of the women who responded to the inquiry influence specific unmet information needs. Most frequently mentioned unmet information needs relate to supplementary naturopathy, nutrition, health-promoting measures, and working during breast cancer. Patients with breast cancer are often provided with large amounts of information during their hospital stay indicating this information is not targeted to patient needs and may be overwhelming. The results show that information on everyday life needs such as supplementary naturopathy were important for the sample newly diagnosed with breast cancer. Employed women in particular have questions regarding working during cancer or tax relief. [ABSTRACT FROM AUTHOR]

This article discusses two of the most used methods of comparative case study research, namely, John Stuart Mill’s (Millian) method of agreement and the method of difference. In doing so, it claims that those methods allow social research to progress theoretically and empirically if the latter is assessed through the epistemological framework of the research program. The latter represents a series of guidelines to assay the progress of science provided by Imre Lakatos’s philosophy of science. In fact, those two methods can be used according to two methodologies, namely, concept formation and causal inference, which in turn perform specific functions essential for social research to develop theoretically and empirically in line with the guidelines established by the research program. In conclusion, a more nuanced discussion of the link between epistemology, methodology, and methods is needed to fully appreciate what comparative case study research is good for.

In the first part of this paper, I present a brief overview of contemporary research addressing key questions about General Systems Theory (GST), such as what it is, what form it might take, whether developing it is a realistic prospect, how close we are to having it and what practical activities could help us develop it further. In the second part, I consider the early general systemists' ambition to leverage GST to build a 'better world', and address the question of what could be meant by this, from a systems perspective. I argue that GST should have a key role in working towards such a world. Copyright © 2015 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Residential group care workers are frequently required to support children with extremely challenging and aggressive behaviour. Our knowledge about the tensions that may exist for workers that manage difficult behaviour is theoretically and empirically underdeveloped. The aim of this exploratory study was to contribute to our understanding of the dynamics of behaviour management in the residential environment by identifying the worker-reported tensions involved in the management of challenging and disruptive behaviour. Seventeen South Australian residential group care workers participated in semi-structured interviews in which they were asked to describe their management of behaviour. These interviews were subjected to thematic analysis. The analysis revealed several dynamics that influence workers' management of challenging behaviour: the sense of parenting at a distance, the pressure for consistency, the desire for balance between control and connection, the desire for normality and the inconsistent nature of relationships. These findings contribute to our knowledge about the interpersonal context in which behaviour is addressed in the residential group home and enhance our understanding of the unique tensions that workers' experience in managing behaviour in the residential environment. The findings have implications for the development of staff training and the support of residential care workers managing challenging behaviour. [ABSTRACT FROM AUTHOR]

This article argues that conventional quantitative and qualitative research methods have largely failed to provide policy practitioners with the knowledge they need for decision making. These methods often have difficulty handling real-world complexity, especially complex causality. This is when the mechanism of change is a combination of conditions that occur in a system such as an organisation or locality. A better approach is to use qualitative comparative analysis (QCA), a hybrid qualitative/quantitative method that enables logical reasoning about actual cases, their conditions and how outcomes emerge from combinations of these conditions. Taken together, these comprise a system, and the method works well with a whole-system view, avoiding reductionism to individual behaviours by accounting for determinants that operate at levels beyond individuals. Using logical reduction, QCA identifies causal mechanisms in sub-types of cases differentiated by what matters to whether the outcome happens or not. In contrast to common variable-based methods such as multiple regression, which are divorced from actual case realities, QCA is case-based and rooted in these realities. The use of qualitative descriptors of conditions such as ways of working engages practitioners, while their standardisation enables systematic comparison and a degree of generalisation about ‘why’ questions that qualitative techniques typically do not achieve. The type of QCA described in the article requires conditions and outcomes to be dichotomised as present or absent, which is helpful to practitioners facing binary decisions about whether to do (a) or (b), or whether or not an outcome has been achieved.

ABSTRACT Children in out-of-home care that demonstrate challenging behaviour are often thought of as 'attachment disordered'. Our understanding of what this might mean for practice is not well developed. In this study, 92 South Australian stakeholders were interviewed about how they understood extremely challenging behaviour amongst school-age children in out-of-home care. Participants consistently described behaviour as arising from attachment difficulties. Despite this, there were a variety of ways that a child's attachment needs were conceptualized, which appeared to be inconsistent with contemporary attachment theory. Thematic analysis yielded four implicit views about children's attachment: attachment as capacity that is limited, attachment as skill that children can learn and transfer to other relationships, attachment as unachievable for some children and an idealized view of attachment as a close and trusting relationship. These possible misconceptions about attachment and attachment needs and their relationship to the development of challenging behaviour are discussed in terms of attachment informed research and theory. The possible implications for placement practice and policy for children in out-of-home care are discussed. [ABSTRACT FROM AUTHOR]

Purpose – Structural equation modelling (SEM) is a method that is very frequently applied by marketing and business researchers to assess empirically new theoretical proposals articulated by means of complex models. It is, therefore, a logical thought that the quality of the new advances in marketing and business theory depends, in part, on how well SEM is applied. This study aims to conduct an extensive review and empirical analysis of a broad variety of classic and recent controversies and issues related with the use of SEM, in order to identify problematic questions and prescribe a compendium of solutions for its suitable application. Design/methodology/approach – The main analyses were conducted on a sample of 191 SEM-based papers and 472 applications, i.e. all the SEM-based studies published in four leading marketing journals during the period 1995-2007. Findings – Despite the maturity of SEM, its application in marketing research still has notable room for improvement. This is a general conclusion based on numerous problems detected and discussed here. Practical implications – The study provides plausible solutions to the problems identified, a useful guide that is easy to follow and to apply adequately to present SEM issues in marketing and business studies. Research limitations/implications – The sample of SEM-based papers and applications is limited to four publication outlets. A wider set or/and other journals different to those analyzed here may be preferred. Originality/value – This is a valuable and timely study of the application of SEM in marketing and business research, and is also useful as a guiding framework for good practice. Likewise, as the problems discussed here presumably occur in other areas of social science, this paper should be welcome beyond the borders of the business disciplines. [ABSTRACT FROM AUTHOR]

Purpose – Latent constructs represent the building blocks of marketing theory. The purpose of this paper is to provide marketing researchers with a practical procedure for writing construct definitions. Design/methodology/approach – The paper reviews important contributions to construct definition in the literature from marketing, management, psychology and the philosophy of science. The authors expound construct definition in both practical and theoretical spheres to motivate the proposed procedure. Findings – A six-step procedure for construct definition and redefinition in marketing is developed. The proposed procedure addresses important aspects of definitions including the level of abstraction, scope, nomological relationships, explanatory and predictive power, ambiguity, vagueness, and preventing construct proliferation. Research limitations/implications – While techniques for developing measures have received a great deal of attention, those for the earlier step of construct definition have not. Researchers will benefit from more precise definitions through improved model specification, better measures, and more reliable determination of the direction of causality. The role of the individual researcher's linguistic skill in construct definition must still be determined. Practical implications – Marketing practitioners can also use the procedure to define latent constructs for which they must develop measures. Originality/value – The literature on construct definition is fragmentary, scattered across disciplines and occasionally even arcane. It is further often descriptive of what a good definition looks like rather than prescriptive of how a good definition can be developed. The six steps are simple, broadly applicable, based on both theory and practical experience, consist of relatively few discrete steps, and feed directly into the modern measure development paradigm in marketing.

Purpose – The purpose of this study is to characterize construction management research at the interface of explanatory science and design science. Design/methodology/approach – The dual nature of construction management research is analyzed by relating this field of research to natural science, design science and its interface. Research at the interface of explanatory science and design science is characterized by identifying studies published on this interface in high quality construction management journals. Findings – Research at this interface should focus on technological rules developed through testing in practical contexts as in design science as well as grounding in the explanatory sciences. The nature of testing technological rules is highly similar to the replication logic recommended for comparative case studies. Research limitations/implications – Developing and testing technological rules combines the design science and the explanatory science mode of knowledge production in construction management research, while it also respects some of the methodological differences between the two modes. Originality/value – Developing and testing technological rules is the common ground on which research in construction management practice and research can meet and reduce the relevance gap between science and the world of practice.

This study identifies the practical and philosophical difficulties associated with testing strategic management and organization theories. Working from a critical realist perspective, we affirm the importance of falsification and verification efforts for progress in theory development. We advocate a four-step approach for advancing theory testing that prioritizes identifying and testing for the presence and effects of hypothesized causal mechanisms, rather than solely focusing on correlational methods to jointly test the set of effects composing a theoretical system. Going beyond prior critical realist writings, we provide practical guidance for deploying established research methods to test management theories. Copyright © 2010 John Wiley & Sons, Ltd.

The year 2011 marks the centenary of Francis Peyton Rous's landmark experiments on an avian cancer virus. Since then, seven human viruses have been found to cause 10-15% of human cancers worldwide. Viruses have been central to modern cancer research and provide profound insights into both infectious and non-infectious cancer causes. This diverse group of viruses reveals unexpected connections between innate immunity, immune sensors and tumour suppressor signalling that control both viral infection and cancer.

To understand organizational, strategic and technological change it would be helpful to resort to mechanisms that are responsible for triggering and directing deep-seated social change processes. Propositions about mechanisms have an interesting epistemological status, they take an intermediate stance between law-like and descriptive statements. On the one hand they designate concrete events and on the other they draw on the causality responsible for the emergence of these events. In this article we describe some fundamental characteristics of mechanisms, describe some important change mechanisms and articulate some desiderata for mechanisms-research. [ABSTRACT FROM AUTHOR]

This article highlights one of the major benefits of qualitative comparative methodology as applied within a “small- N” research design, namely its potential use for specifying the scope conditions of (theoretically competing) causal mechanisms. It is argued that the identification of set-theoretic relationships, multiple paths, and analytic efforts in typological mapping can make valuable contributions to the elaboration and further development of middle-range theory.
