Public Health Psychology: A Conceptual and Practical Framework

Introduction For many years concern for public health has transcended the boundaries of the medical sciences and epidemiology. For the last 50 years or so psychologists have been increasingly active in this field. Recently, psychologists have not only begun to see the need to take action to mould health promoting behaviours in individuals, but have also pointed out the need to join in an effort to develop appropriate social, political, economic and institutional conditions which would help to improve the state of public health. Psychologists have postulated the need to distinguish a new subdiscipline of psychology called public health psychology which, together with other disciplines, would further the realization of this goal. In the following article the historical and international context of health psychology and the changing nature of public health are put forward as having important implications for the establishment of a ‘public health psychology’. These implications are addressed in later sections of the article through the description of conceptual and practical framework of public health psychology in which theory, methods and practice are considered. Many aspects of the conceptual and practical framework of public health psychology have relevance to the health social sciences more generally and forming a basis for interdisciplinary work. The framework of public health psychology, together with the obstacles that need to be overcome, are critically examined within an overall approach that contends it is necessary to increase and improve the contribution of health psychology to public health.

Quantifying the state of populations and effects of disturbances at large spatio-temporal scales: The case of coral populations in the great barrier reef

This project was a step forward in applying statistical methods and models to provide new insights for more informed decision-making at large spatial scales. The model has been designed to address complicated effects of ecological processes that govern the state of populations and uncertainties inherent in large spatio-temporal datasets. Specifically, the thesis contributes to better understanding and management of the Great Barrier Reef.

IgE-Associated IGHV Genes from Venom and Peanut Allergic Individuals Lack Mutational Evidence of Antigen Selection

Antigen selection of B cells within the germinal center reaction generally leads to the accumulation of replacement mutations in the complementarity-determining regions (CDRs) of immunoglobulin genes. Studies of mutations in IgE-associated VDJ gene sequences have cast doubt on the role of antigen selection in the evolution of the human IgE response, and it may be that selection for high affinity antibodies is a feature of some but not all allergic diseases. The severity of IgE-mediated anaphylaxis is such that it could result from higher affinity IgE antibodies. We therefore investigated IGHV mutations in IgE-associated sequences derived from ten individuals with a history of anaphylactic reactions to bee or wasp venom or peanut allergens. IgG sequences, which more certainly experience antigen selection, served as a control dataset. A total of 6025 unique IgE and 5396 unique IgG sequences were generated using high throughput 454 pyrosequencing. The proportion of replacement mutations seen in the CDRs of the IgG dataset was significantly higher than that of the IgE dataset, and the IgE sequences showed little evidence of antigen selection. To exclude the possibility that 454 errors had compromised analysis, rigorous filtering of the datasets led to datasets of 90 core IgE sequences and 411 IgG sequences. These sequences were present as both forward and reverse reads, and so were most unlikely to include sequencing errors. The filtered datasets confirmed that antigen selection plays a greater role in the evolution of IgG sequences than of IgE sequences derived from the study participants.

Validation and reliability of a Spanish version of Simple Shoulder Test (SST-Sp)

Background: The Simple Shoulder Test (SST-Sp) is a widely used outcome measure. Objective: The purpose of this study was to develop and validate a Spanish-version SST (SST-Sp). Methods: A two-stage observational study was conducted. The SST was initially cross-culturally adapted to Spanish through double forward and backward translation and then validated for its psychometric characteristics. Participants (n = 66) with several shoulder disorders completed the SST-Sp, DASH, VAS and SF-12. The full sample was employed to determine factor structure, internal consistency and concurrent criterion validity. Reliability was determined in the first 24–48 h in a subsample of 21 patients. Results: The SST-Sp showed three factors that explained the 56.1 % of variance, and the internal consistency for each factor was α = 0.738, 0.723 and 0.667, and reliability was ICC = 0.687–0.944. The factor structure was three-dimensional and supported construct validity. Criterion validity determined from the relationship between the SST-Sp and DASH was strong (r = −0.73; p < 0.001) and fair for VAS (r = −0.537; p < 0.001). Relationships between SST-Sp and SF-12 were weak for both physical (r = −0.47; p < 0.001) and mental (r = −0.43; p < 0.001) dimensions. Conclusions: The SST-Sp supports the findings of the original English version as being a valid shoulder outcome measure with similar psychometric properties to the original English version.

Quantification of stability in an agility drill using linear and nonlinear measures of variability

This study implemented linear and nonlinear methods of measuring variability to determine differences in stability of two groups of skilled (n = 10) and unskilled (n = 10) participants performing 3m forward/backward shuttle agility drill. We also determined whether stability measures differed between the forward and backward segments of the drill. Finally, we sought to investigate whether local dynamic stability, measured using largest finite-time Lyapunov exponents, changed from distal to proximal lower extremity segments. Three-dimensional coordinates of five lower extremity markers data were recorded. Results revealed that the Lyapunov exponents were lower (P < 0.05) for skilled participants at all joint markers indicative of higher levels of local dynamic stability. Additionally, stability of motion did not differ between forward and backward segments of the drill (P > 0.05), signifying that almost the same control strategy was used in forward and backward directions by all participants, regardless of skill level. Furthermore, local dynamic stability increased from distal to proximal joints (P < 0.05) indicating that stability of proximal segments are prioritized by the neuromuscular control system. Finally, skilled participants displayed greater foot placement standard deviation values (P < 0.05), indicative of adaptation to task constraints. The results of this study provide new methods for sport scientists, coaches to characterize stability in agility drill performance.

An alternative approach to describing agility in sports through establishment of a relationship between velocity and radius of curvature

Agility is an essential part of many athletic activities. Currently, agility drill duration is the sole criterion used for evaluation of agility performance. The relationship between drill duration and factors such as acceleration, deceleration and change of direction, however, has not been fully explored. This paper provides a mathematical description of the relationship between velocity and radius of curvatures in an agility drill through implementation of a power law (PL). Two groups of skilled and unskilled participants performed a cyclic forward/backward shuttle agility test. Kinematic data was recorded using motion capture system at a sampling rate of 200 Hz. The logarithmic relationship between tangential velocity and radius of curvature of participant trajectories in both groups was established using the PL. The slope of the regression line was found to be 0.26 and 0.36, for the skilled and unskilled groups, respectively. The magnitudes of regression line slope for both groups were approximately 0.3 which is close to the expected 1/3 value. Results are an indication of how the PL could be implemented in an agility drill thus opening the way for establishment of a more representative measure of agility performance instead of drill duration.

Real-time wind speed estimation and compensation for improved flight

This paper presents the development and experimental validation of a prototype system for online estimation and compensation of wind disturbances onboard small Rotorcraft unmanned aerial systems (RUAS). The proposed approach consists of integrating a small pitot-static system onboard the vehicle and using simple but effective algorithms for estimating the wind speed in real time. The baseline flight controller has been augmented with a feed-forward term to compensate for these wind disturbances, thereby improving the flight performance of small RUAS in windy conditions. The paper also investigates the use of online airspeed measurements in a closed-loop for controlling the RUAS forward motion without the aid of a global positioning system (GPS). The results of more than 80 flights with a RUAS confirm the validity of our approach.

Media business studies as we see it: Why does it matter, for whom, and how do you get published? [editorial]

To the delight of the renewed editorial team, the Journal of Media Business Studies (JOMBS) receives an increasing number of submissions every week. Given the growing interest in the study of media business, whether from the angle of economics, management, strategy, organisation studies, marketing, consumer behaviour, innovation and entrepreneurship or other contributing disciplines, this editorial aims to clarify how we look at the field and wish to move the journal forward. In particular, we want to address a few questions that we believe are central for those who wish to publish their research with us and thereby contribute to the academic discussion. This article gives a more elaborate explanation to the aims and scope of JOMBS.

A new intelligent algorithm for online voltage stability assessment and monitoring

This paper presents a new approach for assessing power system voltage stability based on artificial feed forward neural network (FFNN). The approach uses real and reactive power, as well as voltage vectors for generators and load buses to train the neural net (NN). The input properties of the NN are generated from offline training data with various simulated loading conditions using a conventional voltage stability algorithm based on the L-index. The performance of the trained NN is investigated on two systems under various voltage stability assessment conditions. Main advantage is that the proposed approach is fast, robust, accurate and can be used online for predicting the L-indices of all the power system buses simultaneously. The method can also be effectively used to determining local and global stability margin for further improvement measures.

Artificial Neural Network Based Automatic Emergency Landing Site Selection for UAVs and Highly Automated Aircraft

In this report an artificial neural network (ANN) based automated emergency landing site selection system for unmanned aerial vehicle (UAV) and general aviation (GA) is described. The system aims increase safety of UAV operation by emulating pilot decision making in emergency landing scenarios using an ANN to select a safe landing site from available candidates. The strength of an ANN to model complex input relationships makes it a perfect system to handle the multicriteria decision making (MCDM) process of emergency landing site selection. The ANN operates by identifying the more favorable of two landing sites when provided with an input vector derived from both landing site's parameters, the aircraft's current state and wind measurements. The system consists of a feed forward ANN, a pre-processor class which produces ANN input vectors and a class in charge of creating a ranking of landing site candidates using the ANN. The system was successfully implemented in C++ using the FANN C++ library and ROS. Results obtained from ANN training and simulations using randomly generated landing sites by a site detection simulator data verify the feasibility of an ANN based automated emergency landing site selection system.

Self-love and self-liking in the moral and political philosophy of Bernard Mandeville and David Hume

This work offers a novel interpretation of David Hume’s (1711–1776) conception of the conjectural development of civil society and artificial moral institutions. It focuses on the social elements of Hume’s Treatise of human nature (1739–40) and the necessary connection between science of man and politeness, civilised monarchies, social distance and hierarchical structure of civil society. The study incorporates aspects of intellectual history, history of philosophy and book history. In order to understand David Hume’s thinking, the intellectual development of Bernard Mandeville (1670–1733) needs to be accounted for. When put into a historical perspective, the moral, political and social components of Treatise of human nature can be read in the context of a philosophical tradition, in which Mandeville plays a pivotal role. A distinctive character of Mandeville and Hume’s account of human nature and moral institutions was the introduction of a simple distinction between self-love and self-liking. The symmetric passions of self-interest and pride can only be controlled by the corresponding moral institutions. This is also the way in which we can say that moral institutions are drawn from human nature. In the case of self-love or self-interest, the corresponding moral institution is justice. Respectively, concerning self-liking or pride the moral institution is politeness. There is an explicit analogy between these moral institutions. If we do not understand this analogy, we do not understand the nature of either justice or politeness. The present work is divided into two parts. In the first part, ‘Intellectual development of Bernard Mandeville’, it is argued that the relevance of the paradigmatic change in Mandeville’s thinking has been missed. It draws a picture of Mandeville turning from the Hobbism of The Fable of the Bees to an original theory of civil society put forward in his later works. In order to make this change more apparent, Mandeville’s career and the publishing history of The Fable of the Bees are examined comprehensively. This interpretation, based partly on previously unknown sources, challenges F. B. Kaye’s influential decision to publish the two parts of The Fable of the Bees as a uniform work of two volumes. The main relevance, however, of the ‘Intellectual development of Mandeville’ is to function as the context for the young Hume. The second part of the work, ‘David Hume and Greatness of mind’, explores in philosophical detail the social theory of the Treatise and politics and the science of man in his Essays. This part will also reveal the relevance of Greatness of mind as a general concept for David Hume’s moral and political philosophy.

Aristotle on the Perception of Perception : Seeing, Remembering, and Sleeping

This study is an inquiry into three related topics in Aristotle’s psychology: the perception of seeing, the perception of past perception, and the perception of sleeping. Over the past decades, Aristotle’s account of the perception of perception has been studied in numerous articles and chapters of books. However, there is no monograph that attempts to give a comprehensive analysis of this account and to assess its relation and significance to Aristotle’s psychological theory in general as well as to other theories pertaining to the topics (e.g. theories of consciousness), be they ancient, medieval, modern, or contemporary. This study intends to fill this gap and to further the research into Aristotle’s philosophy and into the philosophy of mind. The present study is based on an accurate analysis of the sources, on their Platonic background, and on later interpretations within the commentary tradition up to the present. From a methodological point of view, this study represents systematically orientated research into the history of philosophy, in which special attention is paid to the philosophical problems inherent in the sources, to the distinctions drawn, and to the arguments put forward as well as to their philosophical assessment. In addition to contributing many new findings concerning the topics under discussion, this study shows that Aristotle’s account of the perception of perception substantially differs from many later theories of consciousness. This study also suggests that Aristotle be regarded as a consistent direct realist, not only in respect of sense perception, but also in respect of memory.

Public Open Spaces in Kathmandu Valley: A Review of Contemporary Problems and Historic Precedents

The current growth of Kathmandu Valley has been malignant in many ways which suggests a decline of public realm in the city. As the current efforts for planning and design of public open space exhibit numerous problems related to both physical and social aspects of city building, this book examines the shortcomings with contemporary urban development from urban planning and design point of view and attempts to suggest methods to overcome such shortcomings based on the study of historic urban squares. This book identifies the inherent urban design qualities of the historic urban squares in order to learn from them and also attempts to put forward the principles and guidelines for contemporary public space design based on such findings.
