A Theoretical Model to Measure Managerial and Leadership Competence of Business School Managers
A theoretical model to measure managerial competence was developed by evaluating two previous models with similar aims. In addition to the original eight management competencies, another eight competencies were identified and applied to determine the management competencies needed in the Fourth Industrial Revolution with its fast-changing business environment. The article narrows down eleven management competencies and develops measuring criteria for each; in total 42 criteria. The eleven business competencies are leading change, cultural intelligence, team building, conflict management, communication skills, a global leader mindset, emotional intelligence, career awareness, personal value system, and external and ethical influences. The model is a theoretical model and presents management competencies relevant to the modern business environment. The value of this study resides in a strong theoretical basis for postmodern business environmental skills that managers need to maintain completeness of their organizations as well as providing a sound point of departure for other researchers of managerial competence. 
NGOs and government partnership for health systems strengthening: A qualitative study presenting viewpoints of government, NGOs and donors in Pakistan
<p>Abstract</p> <p>Background</p> <p>Health systems are expected to serve the population needs in an effective, efficient and equitable manner. Therefore, the importance of strengthening of public, private and community health systems has been emphasized time and again. In most of the developing countries, certain weaknesses and gaps in the government health systems have been hampering the achievement of improved health outcomes. Public sector in Pakistan has been deficient in the capacity to deliver equitable and quality health services and thus has been grossly underutilized.</p> <p>Methods</p> <p>A qualitative study comprising in-depth interviews was conducted capturing the perceptions of the government functionaries, NGO representatives and donor community about the role and position of NGOs in health systems strengthening in Pakistan's context. Analysis of the data was done manually to generate nodes, sub-nodes and themes.</p> <p>Results</p> <p>Since many years, international and local non-governmental organizations (NGOs) have endeavored to fill the gaps in health service delivery, research and advocacy. NGOs have relatively performed better and achieved the results because of the flexible planning and the ability to design population based projects on health education, health promotion, social marketing, community development and advocacy. This paper captures the need and the opportunity of public private partnership in Pakistan and presents a framework for a meaningful engagement of the government and the private and nonprofit NGOs.</p> <p>Conclusion</p> <p>Involving the NGOs for health system strengthening may eventually contribute to create a healthcare system reflecting an increased efficiency, more equity and good governance in the wake of the Millennium Development Goals. Nevertheless, few questions need to be answered and pre-requisites have to be fulfilled before moving on.</p
Confidence Sets for Ranks with Applications to Intergenerational Mobility and Neighborhoods
It is often desired to rank different populations according to the value of some feature of each population.
For example, it may be desired to rank neighborhoods according to some measure of intergenerational
mobility or countries according to some measure of academic achievement. These rankings are invariably computed using estimates rather than the true values of these features. As a result, there may be
considerable uncertainty concerning the rank of each population. In this paper, we consider the problem
of accounting for such uncertainty by constructing confidence sets for the rank of each population. We
consider both the problem of constructing marginal confidence sets for the rank of a particular population as well as simultaneous confidence sets for the ranks of all populations. We show how to construct
such confidence sets satisfying desired coverage properties under weak assumptions. An important feature of all of our constructions is that they remain computationally feasible even when the number of
populations is very large. We apply our theoretical results to re-examine the rankings of both neighborhoods in the United States in terms of intergenerational mobility and developed countries in terms of
academic achievement. The conclusions about which countries do best and worst at reading, math, and
science are fairly robust to accounting for uncertainty. By comparison, several celebrated findings about
intergenerational mobility in the United states are not robust to taking uncertainty into account
Large tunable image-charge effects in single-molecule junctions
The characteristics of molecular electronic devices are critically determined
by metal-organic interfaces, which influence the arrangement of the orbital
levels that participate in charge transport. Studies on self-assembled
monolayers (SAMs) show (molecule-dependent) level shifts as well as
transport-gap renormalization, suggesting that polarization effects in the
metal substrate play a key role in the level alignment with respect to the
metal's Fermi energy. Here, we provide direct evidence for an electrode-induced
gap renormalization in single-molecule junctions. We study charge transport in
single porphyrin-type molecules using electrically gateable break junctions. In
this set-up, the position of the occupied and unoccupied levels can be followed
in situ and with simultaneous mechanical control. When increasing the electrode
separation, we observe a substantial increase in the transport gap with level
shifts as high as several hundreds of meV for displacements of a few \aa
ngstroms. Analysis of this large and tunable gap renormalization with
image-charge calculations based on atomic charges obtained from density
functional theory confirms and clarifies the dominant role of image-charge
effects in single-molecule junctions
Finite- and Large-Sample Inference for Ranks using Multinomial Data with an Application to Ranking Political Parties
It is common to rank different categories by means of preferences that are revealed through data on choices. A prominent example is the ranking of political candidates or parties using the estimated share of support each one receives in surveys or polls about political attitudes. Since these rankings are computed using estimates of the share of support rather than the true share of support, there may be considerable uncertainty concerning the true ranking of the political candidates or parties. In this paper, we consider the problem of accounting for such uncertainty by constructing confidence sets for the rank of each category. We consider both the problem of constructing marginal confidence sets for the rank of a particular category as well as simultaneous confidence sets for the ranks of all categories. A distinguishing feature of our analysis is that we exploit the multinomial structure of the data to develop confidence sets that are valid in finite samples. We additionally develop confidence sets using the bootstrap that are valid only approximately in large samples. We use our methodology to rank political parties in Australia using data from the 2019 Australian Election Survey. We find that our finite-sample confidence sets are informative across the entire ranking of political parties, even in Australian territories with few survey respondents and/or with parties that are chosen by only a small share of the survey respondents. In contrast, the bootstrap-based confidence sets may sometimes be considerably less informative. These findings motivate us to compare these methods in an empirically-driven simulation study, in which we conclude that our finite-sample confidence sets often perform better than their large-sample, bootstrap-based counterparts, especially in settings that resemble our empirical application
Association of psychological distress, quality of life and costs with carpal tunnel syndrome severity: a crosssectional analysis of the PALMS cohort
Objectives:
The PALMS study is designed to identify prognostic factors for outcome from corticosteroid injection and surgical decompression for carpal tunnel syndrome (CTS) and predictors of cost over 2 years. The aim of this paper is to explore the cross-sectional association of baseline patient-reported and clinical severity with anxiety, depression, health-related quality of life and costs of CTS in patients referred to secondary care.
Methods:
Prospective, multi-centre cohort study initiated in 2013. We collected baseline data on patientreported symptom severity (CTS-6), psychological status (HADS), hand function (Michigan Hand Questionnaire) comorbidities, EQ5D-3L and sociodemographic variables. Nerve conduction tests classified patients into five severity grades (mild to very severe). Data were analysed using a general linear model.
Results:
753 patients with CTS provided complete baseline data. Multivariable linear regression adjusting for age, sex, ethnicity, duration of CTS, smoking status, alcohol consumption, employment status, body mass index and comorbidities showed a highly statistically significant relationship between CTS-6 and anxiety, depression and the EQ-5D (p<0.0001 in each case). Likewise, a significant relationship was observed between electrodiagnostic severity and anxiety (p=0.027) but not with depression (p=0.986) or the EQ-5D (p=0.257). NHS and societal costs in the 3 months prior to enrolment were significantly associated with self-reported severity (p<0.0001) but not with electrodiagnostic severity.
Conclusions:
Patient-reported symptom severity in carpal tunnel syndrome is significantly and positively associated with anxiety, depression, health-related quality of life and NHS and societal costs even when adjusting for age, gender, body mass index, comorbidities, smoking, drinking and occupational status. In contrast there is little or no evidence of any relationship with objectively derived CTS severity. Future research is needed to understand the impact of approaches and treatments that
address psychosocial stressors as well as biomedical factors on relief of symptoms from carpal tunnel syndrome.CJH was funded by the National Institute for Health Research (NIHR) through a NIHR Senior Research Fellowship. ECFW is funded by the NIHR Cambridge Biomedical Research Centre
Successful Reversal of Acute Kidney Failure by Ultrasound-Accelerated Thrombolysis of an Occluded Renal Artery
Purpose. To describe the treatment of renal artery thrombosis with ultrasound-accelerated thrombolysis and discuss the management of prolonged renal ischemia. Case. A 76-year-old patient with a single functional kidney, mild chronic renal impairment, and a recent history of endovascular repair of a thoracoabdominal aneurysm with an aortic branch graft presented with acute flank pain, anuria, and renal failure. The side branch from the aortic stent graft to his single, right, functional kidney appeared to be completely thrombosed. Symptoms had started after cessation of oral anticoagulants because of a planned mastectomy for breast cancer. After identification of the occlusion, ultrasound-accelerated thrombolysis was started 19 hours after the onset of anuria. Angiography, 4 hours after beginning of therapy, already showed partial dissolution of the thrombus and angiographic control after 18 hours showed complete patency of the renal artery side branch. Despite a long period of ischemia, renal function was completely recovered. Conclusion. In patients with acute renal ischemia due to thrombosis of the renal artery, complete recovery of function can be achieved with ultrasound-accelerated thrombolysis, even after prolonged periods of ischemia
