Grandiose Narcissism Predicts Willingness to Behave Badly, Without Proportional Tolerance for Others’ Bad Behavior

Narcissists characteristically behave badly; our study investigated how they respond to experiencing others’ bad behavior. After completing the Narcissistic Personality Inventory, a measure of grandiose narcissism, participants reported their willingness to engage in different inconsiderate or unethical common behaviors. Then they reported how bothered they would feel in response to experiencing each of the same bad behaviors—perpetrated by someone else. Participants overall reported feeling bothered by others’ bad behavior, but narcissism was unrelated to intolerance judgments. Narcissists are often highly reactive when their inflated self-views are challenged, but our study suggests that narcissists are not uniquely bothered by everyday minor offenses. However, when viewed from a different angle, narcissists’ level of intolerance could be interpreted as unjustly high, because they reported more willingness to engage in behavior that could bother others, yet did not show proportional tolerance for others’ bothersome behavior

Does the professional and working context of United Kingdom clinicians predict if they use practices to support patients with long term conditions to self manage?

INTRODUCTION: Our study examines how the professional and employment context may influence clinicians' practice self management support for patients with long term conditions (LTC). MATERIAL AND METHODS: We surveyed clinicians working with patients with depression, chronic obstructive pulmonary disorder (COPD), chronic musculo skeletal pain and diabetes. RESULTS: Clinicians most frequently endorsed items on a scale concerned with patient centeredness, and less frequently endorsed items concerned with clinical and organizational self management support. The most important factors predicting these latter activities were the intensity of working experience with patients with LTC and attending professional training addressing the principles and practice of self management support. Practicing patient centeredness was endorsed by nearly all respondents, and so was not sensitive to variation on work variables. CONCLUSIONS: The interaction of training and intensity of work with patients with LTC seems to have the most powerful effect on undertaking clinical and organizational self management support practices. To facilitate clinicians' practice of self management support for patients with LTC it is very important to provide relevant professional training and to build specialized patient care teams with professionals having complimentary skills

Assessment of the learning curve in health technologies: a systematic review

Objective: We reviewed and appraised the methods by which the issue of the learning curve has been addressed during health technology assessment in the past. Method: We performed a systematic review of papers in clinical databases (BIOSIS, CINAHL, Cochrane Library, EMBASE, HealthSTAR, MEDLINE, Science Citation Index, and Social Science Citation Index) using the search term "learning curve:" Results: The clinical search retrieved 4,571 abstracts for assessment, of which 559 (12%) published articles were eligible for review. Of these, 272 were judged to have formally assessed a learning curve. The procedures assessed were minimal access (51%), other surgical (41%), and diagnostic (8%). The majority of the studies were case series (95%). Some 47% of studies addressed only individual operator performance and 52% addressed institutional performance. The data were collected prospectively in 40%, retrospectively in 26%, and the method was unclear for 31%. The statistical methods used were simple graphs (44%), splitting the data chronologically and performing a t test or chi-squared test (60%), curve fitting (12%), and other model fitting (5%). Conclusions: Learning curves are rarely considered formally in health technology assessment. Where they are, the reporting of the studies and the statistical methods used are weak. As a minimum, reporting of learning should include the number and experience of the operators and a detailed description of data collection. Improved statistical methods would enhance the assessment of health technologies that require learning

Assessing the learning curve effect in health technologies: Lessons from the non-clinical literature

Introduction: Many health technologies exhibit some form of learning effect, and this represents a barrier to rigorous assessment. It has been shown that the statistical methods used are relatively crude. Methods to describe learning curves in fields outside medicine, for example, psychology and engineering, may be better. Methods: To systematically search non–health technology assessment literature (for example, PsycLit and Econlit databases) to identify novel statistical techniques applied to learning curves. Results: The search retrieved 9,431 abstracts for assessment, of which 18 used a statistical technique for analyzing learning effects that had not previously been identified in the clinical literature. The newly identified methods were combined with those previously used in health technology assessment, and categorized into four groups of increasing complexity: a) exploratory data analysis; b) simple data analysis; c) complex data analysis; and d) generic methods. All the complex structured data techniques for analyzing learning effects were identified in the nonclinical literature, and these emphasized the importance of estimating intra- and interindividual learning effects. Conclusion: A good dividend of more sophisticated methods was obtained by searching in nonclinical fields. These methods now require formal testing on health technology data sets

Improved Convergence Bounds For Operator Splitting Algorithms With Rare Extreme Errors

In this paper, we improve upon our previous work[24,22] and establish convergence bounds on the objective function values of approximate proximal-gradient descent (AxPGD), approximate accelerated proximal-gradient descent (AxAPGD) and approximate proximal ADMM (AxWLM-ADMM) schemes. We consider approximation errors that manifest rare extreme events and we propagate their effects through iterations. We establish probabilistic asymptotic and non-asymptotic convergence bounds as functions of the range (upper/lower bounds) and variance of approximation errors. We use the derived bound to assess AxPGD in a sparse model predictive control of a spacecraft system and compare its accuracy with previously derived bounds

Mechanisms of fractures in ankle and hind-foot injuries to front seat car occupants - an in-depth accident data analysis

An in-depth analysis of 200 Abbreviated Injury Score (AIS) 2+ injuries to the lower extremity in frontal collisions has been performed using impairment scales devised by the American Orthopaedic Foot and Ankle Society. The most important subgroup of injuries were identified as ankle/hindfoot injuries. There were 63 such injuries sustained by 53 occupants and these were analyzed in greater depth. Inversion or eversion was identified as the mechanism of injury for 40 % of injuries. However in 70% of these fractures caused by inversion or eversion, minimal or no long term impairment would be expected Injuries associated with significant long-term impairment were attributed to axial forces (i.e. loads perpendicular to the foot). Combined vehicle/injury analysis demonstrated a strong association between toe-pan intrusion and these injuries. Interaction between the occupant and the pedals was identified as a probable injury source in only 25% of injuries to the ankle and hindfoot. The results of this study are being used to plan a program of biomechanical research to establish injury risk functions for the ankle and hindfoot. © Copyright 1997 Society of Automotive Engineers, Inc

Early childhood caries, primary caregiver oral health knowledge and behaviours and associated sociological factors in Australia: A systematic scoping review

Background Early childhood caries disproportionately affects vulnerable groups and remains a leading cause of preventable hospital admissions for Western Australian children. The Western Australia State Oral Health Plan seeks to improve child oral health through universal and targeted health promotion initiatives with primary caregivers. These initiatives require evidence of primary caregiver oral health knowledge and behaviours and baseline data on early childhood caries. The objective of this systematic scoping review was to understand current oral health knowledge and practices of primary caregivers of children aged 0–4 years, identify influential socioecological determinants, and identify data on early childhood caries in the Western Australian context. Methods A systematic scoping review framework identified articles published between 2010 and 2021, using Scopus, PubMed, Medline, CINAHL, PsycINFO, selected article reference lists, and oral health websites. The lack of Western Australian specific literature prompted the inclusion of Australia-wide articles. Articles were screened via author consensus, with eight selected. Results Western Australia and nation-wide data on early childhood caries are limited and mostly dated. WA data from children aged 2–3 years, collected in 2006, suggests the prevalence is 2.9% in this state, with national data of children from 0 to 3 years, collected from 2006 and 2008, suggesting an early childhood caries prevalence of 3.4–8% of children aged 18 months, rising sharply by 36 months of age. Nationally, fewer than half the primary caregivers reported following evidence-based oral health recommendations for their young children. Perceptions of the role of dental services for young children tends to be focussed on treatment, rather than surveillance and prevention. Knowledge of dietary and oral hygiene practices is inconsistent and awareness of the Child Dental Benefit Schedule low. Young children’s oral health status is clearly associated with socioecological factors, including socioeconomic status. Conclusions Recent early childhood caries data and evidence of primary care-givers’ oral health knowledge and behaviours are unavailable in Western Australia, a similar situation exists nationwide. To realise the Western Australian and National Oral Health Plans, research is required to address this knowledge gap
