BRIDGING A SUPPOSEDLY UNBRIDGEABLE GAP: ELABORATING SCIENTIFIC KNOWLEDGE FROM AND FOR PRACTICE

This article aims at advancing the still on-going conversations about the so-called research/practice gap. Some academics argue that it is not possible to develop knowledge that is both academically valuable and helpful for practice, while others hold the opposite view, justifying it on the basis of works published in top tier journals. The paper argues that the main reason scholars hold such contradictory views on this topic central to management science is the lack of explicitness of a number of founding assumptions which underlie their discourses, in particular the lack of explicitness of the epistemological framework in which the parties' arguments are anchored. The paper presents methodological guidelines for elaborating scientific knowledge both from and for practice, and illustrates how to use these guidelines on examples from a published longitudinal research project. In order to avoid the lack of explicitness pitfall, the paper specifies scientific and epistemological frameworks in which the knowledge elaborated in this methodological approach, when properly justified, can be considered as legitimate scientific knowledge.collaborative research ; constructivist epistemological paradigm ; sciences of the artificial ; organizational design science; rigor; actionability

Loyal after the End: The Endurance of Organizational Identification

This paper develops and tests a model of the role of organizational identification in members’ propensity to express loyalty to a defunct organization through participation in activities that sustain its most valued elements. It also identifies four antecedent factors to organizational identification that can explain its persistence after formal organizational membership ends as well as the effects of loyalty behaviors. Survey results were analyzed using confirmatory factor analysis and structural equation modeling procedures. The resulting model demonstrated strong fit with the data according to several goodness-of-fit indices

Intracoronary EnalaPrilat to Reduce MICROvascular Damage During Percutaneous Coronary Intervention (ProMicro) study.

Intracoronary angiotensin-converting enzyme inhibitors have been shown to relieve myocardial ischemia in stable patients and to improve epicardial flow in patients with ST-segment elevation myocardial infarction. Yet, it is still unclear whether these effects are mediated by a modulation of the coronary microcirculation. Methods We randomly assigned 40 patients to receive either an intracoronary bolus of enalaprilat (50 g) or placebo before elective PCI. The index of microvascular resistance was measured at baseline, 10 minutes after study drug administration, and after PCI. High-sensitivity cardiac troponin T was measured as a marker of myocardial injury. Results Infusion of enalaprilat resulted in a significant reduction in index of microvascular resistance (27 11 at baseline vs. 19 9 after drug vs. 15 8 after PCI), whereas a significant post-procedural increase in index of microvascular resistance levels was observed in the placebo group (24 15 at baseline vs. 24 15 after drug vs. 33 19 after PCI). Index of microvascular resistance levels after PCI were significantly lower in the enalaprilat group (p 0.001). Patients pre-treated with enalaprilat also showed lower peak values (mean: 21.7 ng/ml, range: 8.2 to 34.8 ng/ml vs. mean: 32.3 ng/ml, range: 12.6 to 65.2 ng/ml, p 0.048) and peri-procedural increases of high-sensitivity cardiac troponin T (mean: 9.9 ng/ml, range: 2.7 to 19.0 ng/ml vs. mean: 26.6 ng/ml, range: 6.3 to 60.5 ng/ml, p 0.025). Conclusions Intracoronary enalaprilat improves coronary microvascular function and protects myocardium from procedurerelated injury in patients with coronary artery disease undergoing PCI. Larger studies are warranted to investigate whether these effects of enalaprilat could result into a significant clinical benefit.

Designing a complex intervention for dementia case management in primary care

Background: Community-based support will become increasingly important for people with dementia, but currently services are fragmented and the quality of care is variable. Case management is a popular approach to care co-ordination, but evidence to date on its effectiveness in dementia has been equivocal. Case management interventions need to be designed to overcome obstacles to care co-ordination and maximise benefit. A successful case management methodology was adapted from the United States (US) version for use in English primary care, with a view to a definitive trial. Medical Research Council guidance on the development of complex interventions was implemented in the adaptation process, to capture the skill sets, person characteristics and learning needs of primary care based case managers. Methods: Co-design of the case manager role in a single NHS provider organisation, with external peer review by professionals and carers, in an iterative technology development process. Results: The generic skills and personal attributes were described for practice nurses taking up the case manager role in their workplaces, and for social workers seconded to general practice teams, together with a method of assessing their learning needs. A manual of information material for people with dementia and their family carers was also created using the US intervention as its source. Conclusions: Co-design produces rich products that have face validity and map onto the complexities of dementia and of health and care services. The feasibility of the case manager role, as described and defined by this process, needs evaluation in ‘real life’ settings

Cell Therapy for Cardiovascular Disease: A Comparison of Methods of Delivery

The field of myocardial regeneration utilizing novel cell-based therapies, gene transfer, and growth factors may prove to play an important role in the future management of ischemic heart disease and cardiomyopathy. Phases I and II clinical trials have been published for a variety of biologics utilizing four methods of delivery: systemic infusion, intracoronary infusion, transvenous coronary sinus, and intramyocardial. This review discusses the advantages and disadvantages of the delivery approaches above

Ambidexterity for corporate social performance

The literature on corporate social performance advocates that firms address social issues based on instrumental as well as moral rationales. While both rationales trigger initiatives to increase corporate social performance, these rest on fundamentally different and contradicting foundations. Building on the literature on organizational ambidexterity and paradox in management, we propose in this conceptual article that ambidexterity represents an important determinant of corporate social performance. We explain how firms achieve higher levels of corporate social performance through the ambidextrous ability to simultaneously pursue instrumentally and morally driven social initiatives. We distinguish between a balance dimension and a combined dimension of ambidexterity, which both enhance corporate social performance through distinct mechanisms. With the balance dimension, instrumental and moral initiatives compensate for each other – which increases the scope of corporate social performance. With the combined dimension, instrumental and moral initiatives supplement each other – which increases the scale of corporate social performance. The article identifies the most important determinants and moderators of the balance and the combined dimension to explain the conditions under which we expect firms to increase corporate social performance through ambidexterity. By focusing on the interplay and tensions between different types of social initiatives, an ambidextrous perspective contributes to a better understanding of corporate social performance. Regarding managerial practice, we highlight the role of structural and behavioral factors for achieving higher corporate social performance through the simultaneous pursuit of instrumental and moral initiatives

Left ventricular systolic dysfunction, heart failure, and the risk of stroke and systemic embolism in patients with atrial fibrillation : insights from the ARISTOTLE trial

We examined the risk of stroke or systemic embolism (SSE) conferred by heart failure (HF) and left ventricular systolic dysfunction (LVSD) in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation Trial (ARISTOTLE), as well as the effect of apixaban versus warfarin

What we talk about when we talk about "global mindset": managerial cognition in multinational corporations

Recent developments in the global economy and in multinational corporations have placed significant emphasis on the cognitive orientations of managers, giving rise to a number of concepts such as “global mindset” that are presumed to be associated with the effective management of multinational corporations (MNCs). This paper reviews the literature on global mindset and clarifies some of the conceptual confusion surrounding the construct. We identify common themes across writers, suggesting that the majority of studies fall into one of three research perspectives: cultural, strategic, and multidimensional. We also identify two constructs from the social sciences that underlie the perspectives found in the literature: cosmopolitanism and cognitive complexity and use these two constructs to develop an integrative theoretical framework of global mindset. We then provide a critical assessment of the field of global mindset and suggest directions for future theoretical and empirical research
