Divine powers and exchange with ‘others’ in Melanesia

In memory of Marshall Sahlins. Marshall Sahlins described divine king forms for a wide range of societies from Southeast Asia, Africa, and the Paciﬁc, among others. In this article, I document a divine king form among the Fuyuge people of the Papuan highlands, revising my previous understanding of this powerful ﬁgure. At the same time, I argue there is an inextricable connection between Sahlins’s theory of divine power and Marilyn Strathern’s model of Melanesian gift exchange: both operate according to distinct ideas of otherness. The capacity to engage in transaction derives from cosmological sources while evidence of cosmological power is provided by the ability to engage in transactions with others in effective and powerful ways. More generally, I argue that conventional Melanesian ﬁgures of big-men, great men, and chiefs are all versions of the alterity of power in related political forms; each instantiates the mutual relations between cosmological and transactional otherness.
Broadband circularly polarized antenna with moon‐shaped parasitic element

A broadband circularly polarized (CP) circular patch antenna with an L‐shaped ground plane and parasitic element is studied. The use of this L‐shaped ground is to achieve short probe feed connection to the circular patch, while maintaining a certain height between the circular patch and ground plane, so that good impedance matching and bandwidth enhancement can be attained. To achieve CP radiation, two notches are initially loaded diagonally into the circular patch, and to further enhance the CP bandwidth, a novel technique of loading a small size moon‐shaped parasitic element into the notched circular patch is proposed. By doing so, the CP bandwidth of proposed antenna can be tremendously increased by approximately 10%. The experimental results show that the proposed CP antenna can yield impedance bandwidth and CP bandwidth of 835–1150 MHz and 839–968 MHz, respectively, with good gain level of 7.6 dBic. Therefore, this proposed wideband CP antenna can be used for UHF (ultrahigh frequency) RFID (radio frequency identification) reader antenna that operates within the universal RFID bands (840 − 960 MHz). © 2016 Wiley Periodicals, Inc.

The Effect of Inclination on the Passive cooling of the solar PV panel by using Phase change Material

A two-dimensional (2D) numerical model was used to simulate the use of a phase change material and inner fins incorporated to a PV panel, in order to control the temperature rise of the PV cells at various inclination angles from 0 o to 90o with respect to vertical at increments of 15°. The PCM (RT25) is placed in a cavity directly in contact with the PV panel. This cavity enclosed on both sides by aluminum layers, and contains extended surfaces (fins). This PV-PCM system is studied numerically using finite volume method. The predicted temperatures have been compared with experimental and numerical data of the literature and a good agreement was obtained for both the isothermal contours and time evolution of the temperature. The bulk of the PCM melting within the system is dominated by natural convection for angle inclination lower than 45 o. In other hand, for the inclinations higher than 45o the heat transfer in conduction mode increases until at 90o, where natural convection disappears completely and the conduction manifests alone. The obtained results reveals that the temperature of the PV panel increases with the increase of the inclination and that small inclinations (lower than 45 o) allow for a better cooling of this panel.
An Unfortunate Case of Takotsubo Cardiomyopathy During Plasmapheresis for Myasthenia Crisis

A literature review shows scarce reports of myasthenic crises (MC) complicated by Takotsubo cardiomyopathy (TC). This patient cohort (0.11%) has higher all-cause mortality and prolonged in-hospital course. We present a rare case of a 72-year-old man who developed cardiogenic shock post-plasmapheresis for myasthenia crisis. He became hemodynamically unstable and developed acute respiratory failure requiring intubation 30 minutes after completion of plasma exchange. Serum troponin peaked at 3.19 ng/mL while an emergent 12-lead electrocardiogram (EKG) showed new-onset diffuse ST-segment elevation. Hypokinesis of the entire apex, anterior septum, mid-and apical inferior septum, and mid-and apical inferior wall consistent with Takotsubo cardiomyopathy was seen on bedside echocardiogram. The patient received a continuous infusion of norepinephrine and vasopressin. The hospital course was complicated by multiorgan failure and eventual demise. This case highlights MC and the potential of plasma exchange therapy to induce TC.
Validation of Fiber-Based Distributed Plasticity Approach for Steel Bracing Models

Nonlinear analysis approach is not anymore limited only to research purposes, but becoming more popular as a tool that can be used during design, thanks to the increased efficiency of computer software and hardware. An accurately calibrated numerical model may simulate the behaviour of buildings in a quite realistic way, which helps designers understand better the performance of their structures. However, the feasibility of the nonlinear analysis approach is limited by the complexity of the numerical model, and the aim of any researcher or engineer is to obtain the most useful information in a reasonable amount of time. This study focuses on the validation of a simplified numerical modelling approach to simulate the nonlinear behaviour of steel bracings. The paper presents a comparison between two different modelling approaches; a refined finite element model using volumetric elements, and fiber-based model using beam elements with distributed plasticity. The numerical models calibrated with the experimental result from existing literature, reproduce the behaviour of cold formed square, and hot rolled open section steel elements under inelastic cyclic loading. The hysteresis loops obtained from two models show that the accuracy obtained by simpler fiber-element formulation is quite close to the more refined volumetric model. Finally, in order to assess the accuracy of the fiber-based modelling approach to estimate the nonlinear cyclic response of full-scale braced frame configurations, two real scale frames are analysed, and the results are compared with the results of the experiments performed on the test frames. In terms of computation time and accuracy, distributed plasticity model is much more efficient, and can be a good option to perform nonlinear analysis of multi-level buildings, which would be quite cumbersome with volumetric modelling approach. This study has been realized thanks to the research fund received from European commission with the contract MEAKADO RFSR-CT-2013-00022.
Effect of Applying Cold Plasma on Structural, Antibacterial and Self Cleaning Properties of α-Fe2O3 (HEMATITE) Thin Film

Objective: In this study, α-Fe2O3 thin film was formed on a glass substrate to study the impact of adding cold plasma on the self-cleaning and antibacterial properties of the samples. Method: The samples were synthesized using the chemical spray pyrolysis (CSP) method at 450°C. X-ray powder diffraction (XRD), scanning electron microscope (FESEM), energy-dispersive X-ray spectroscopy (EDS), and atomic force microscope were used to investigate the morphological and structural characteristics of α-Fe2O3 thin layers prior to and following plasma injection. Finding: The degree of wettability and antibacterial characteristics of iron oxide (hematite) thin film were evaluated in the presence of gram-negative and gram-positive bacteria prior to and following plasma injection, given the great potential of plasma injection in the surface modification of thin films. Novelty: The findings indicate that exposing plasma to α-Fe2O3thin film produces substantial changes in morphology, self-cleaning, and antibacterial characteristics.

The effect of financial and non-financial performance on investors’ reactions: The role of corporate governance mechanisms as moderating

The purpose of this study is to examine the effect of financial and non-financial performance on investor reactions and the role of corporate governance mechanisms as moderating. The analysis technique used is the moderated regression analysis (MRA). The research population is manufacturing sector companies listed on the Indonesia Stock Exchange (IDX). Based on the purposive sampling method, 78 companies were selected as the samples (390 firm-year observations). The results of this study provide empirical evidence that the existence of financial and non-financial performance in a company can increase investor reactions. Institutional ownership plays a role in the relationship between financial performance and investor reactions. Meanwhile, independent commissioners, boards of directors, and audit committees have no role in the relationship between financial performance and investor reactions. And independent commissioners and institutional ownership can moderate the influence of non-financial performance on investor reactions. Meanwhile, the board of directors and audit committee cannot moderate the influence of non-financial performance on investor reactions.
A Preliminary Investigation into Cognitive Aptitudes Predictive of Overall MQ-1 Predator Pilot Qualification Training Performance

Abstract : United States Air Force MQ-1 Predator remotely piloted aircraft pilots are critical assets in a challenging, high-risk, and rapidly evolving aviation career field. However, the Air Force has had difficulties over the past decade recruiting candidates with the right stuff and filling Predator pilot vacancies. The purpose of this study was to evaluate computer-based intelligence and neuropsychological testing on training candidates (n = 235) obtained during medical flight screening and prior to training that distinguishes elite vs. adequate MQ-1 qualification training performance. Findings reveal a combination of cognitive aptitudes that distinguish elite levels of training performance among those selected for this career field. Results may be utilized to improve personnel selection and aeromedical screening procedures for identifying suitable candidates for this high-risk, high-demand occupation.
Prediction of wrinkle types in tube hydroforming under pulsating hydraulic pressure with axial feeding

Wrinkling frequently occurs in tube hydroforming, resulting in an undesirable loss of quality and precision of the formed workpiece, and is generally regarded as a defect. However, wrinkling can also be utilised to improve the formability of tubular materials if it can be gradually reduced or even flattened in the follow-up tube hydroforming. For this reason, wrinkling is classified into two types—harmful wrinkle and useful wrinkle. In this paper, two prediction methods, geometry-based prediction method and mechanics-based prediction method, are proposed to predict the wrinkle type occurring in tube hydroforming under pulsating hydraulic pressure with axial feeding. Then, the corresponding tube hydroforming experiments are presented, which were carried out to validate the two proposed prediction methods by comparing the deformation and wrinkling behaviours. Finally, the characteristics of the two approaches are compared and discussed. The results indicate that the wrinkle type occurring in the present tube hydroforming experiments under pulsating hydraulic pressure with axial feeding could be predicted by both prediction methods, with the geometry-based prediction method providing more accuracy than the mechanics-based prediction method.
Computer simulation study of human locomotion with a three-dimensional entire-body neuro-musculo-skeletal model: (II. Biomechanical relationship between walking stability and neuro-musculo-skeletal system)

It is essential for the biomechanical study of human walking motion to consider not only in vivo mechanical load and energy efficiency but also aspects of motor control such as walking stability. In this study, walking stability was investigated using a three-dimensional entire body neuro -musculo skeletal model in the computer simulation. In the computational experiments, imaginary constraints, such as no muscular system, were set in the neuro-musculo-skeletal model to investigate their influence on walking stability. The neuronal parameters were adjusted using numerical search techniques in order to adapt walking patterns to constraints on the neuro musculo-skeletal system. Simulation results revealed that the model of the normal neuro-musculo-skeletal system yielded a higher stability than the imaginary models. Unstable walking by a model with a time delay in the neuronal system suggested significant unknown mechanisms which stabilized walking patterns that have been neglected in previous studies.
Conceptual Study of Production Technology of Free-Form Concrete Segments

Free-form designs are increasing which is beyond a simple design form to meet the requirements of clients wishing to improve the building value and of the government for symbolic buildings. Furthermore, development of construction technologies, materials and equipment has led to production and installation of free-form concrete. However, unlike the fixed form, free-form concrete requires more time and manpower. In particular, mold for production of free-form materials can be used only once, which implies that excessive resources are input for mold manufacturing. This may result in reduced productivity, increased cost and extended construction duration. It is necessary to develop technologies that can solve the limitation in relation to cost, time, quality and safety so as to ensure economic feasibility and constructability of the free-form buildings. In this regard, the study intends to analyze the problems of producing free-form concrete and construction using such concrete, and to conduct a conceptual study on the technology that is capable of solving the problems. The study draws the requirements of production technology of free-form concrete, and proposes the production technology that can solve the existing problems.
Infection Control Practices among Laboratory Healthcare Workers in an Urban Local Government Area of Lagos State, Nigeria

Background: Laboratory healthcare workers do handle a wide range of potentially dangerous materials which exposes them to numerous hazards. This study aimed to assess the practices of laboratory health care workers towards safety, infection control and the associated factors to its practices. Case Presentation: A cross-sectional study was conducted among 181 laboratory healthcare workers in all registered 33 laboratory facilities in Ikeja Local Government Area in 2017. Data were collected with pre-tested, structured self-administered questionnaires. Data analysed with SPSS version 20 and p-value of < 0.05. The mean age of respondents was 35.0 ± 2.45 years, most of whom were females (57.7%) and married (61.1%). The majority (98.9%) demonstrated good knowledge of infection control. A total of 62.3% identified hand washing as the most important infection control practice while HIV and Tuberculosis were diseases respondents majorly considered as high risk of contracting. A total of 84.6% of the respondents showed good practices. Limited availability of personal protective equipment in the laboratories was a major barrier identified by 98.1% of respondents. Respondents displayed good knowledge, attitude and practice of infection control. Discussion and Conclusion: Barrier to infection control was the limited availability of personal protective equipment. Therefore, concerted efforts should be mustered to ensure continuous training and retraining with the provision of personal protective equipment.
Mobile Technologies in the Field: iPads – Rescuer or Rescuee?

Universities are being swamped by waves of emergent technologies and the emergence of iPads is the latest state-of-the-art‘ mobile device to receive attention. While a number of iPad trials and initiatives have been conducted within the confines of classrooms, for example, Bond University, University of Melbourne and Adelaide University (Brand & Kinash, 2010; Jennings et al 2010; Cross, 2010); far fewer have been conducted in the field, see Duke University‘s use of iPad as a field research tool (Winograd, 2010). This study reports a faculty‘s trial to explore how far iPads could be integrated into a field setting for training of paramedic students in Wilderness Medicine. As it turned out, the remote setting for the exercise presented a number of challenges for the coordinators. Questions that needed to be considered included how ―mobile‖ is the iPad? , How can it be used to support and enhance students‘ learning in the field? , How far could the iPad be extended where Internet connectivity is intermittent? The iPad trial highlighted a lack of a ―common language‖ within the faculty as a basis to collaborate and design learning activities. It provided impetus for an ongoing series of conversations amongst the coordinators and others in the Faculty about design approaches and the need for a pedagogical framework to integrate technologies that support teaching and learning activities. Introduction Since its release in early 2010, iPads have been a phenomenal success for Apple and made significant inroads into consumer and business markets, and now the education sector. Articles with headlines like ―Will iPads transform Med school? ‖ (White, 2010) and statements such as ―DOMINIC RISI was once reluctant to pick up a
Peritraumatic Stress From a Disaster Increases Risk for Onset of Chronic Diseases Among Older Adults

Abstract Background and Objectives Our understanding of the impact of disaster exposure on the physical health of older adults is largely based on hospital admissions for acute illnesses in the weeks following a disaster. Studies of longer-term outcomes have centered primarily on mental health. Missing have been studies examining whether exposure to disaster increases the risk for the onset of chronic diseases. We examined the extent to which 2 indicators of disaster exposure (geographic exposure and peritraumatic stress) were associated with new onset of cardiovascular disease, diabetes, arthritis, and lung disease to improve our understanding of the long-term physical health consequences of disaster exposure. Research Design and Methods We linked self-reported data collected prior to and following Hurricane Sandy from a longitudinal panel study with Medicare data to assess time to new onset of chronic diseases in the 4 years after the hurricane. Results We found that older adults who reported high levels of peritraumatic stress from Hurricane Sandy had more than twice the risk of experiencing a new diagnosis of lung disease, diabetes, and arthritis in the 4 years after the hurricane compared to older adults who did not experience high levels of peritraumatic stress. Geographic proximity to the hurricane was not associated with these outcomes. Analyses controlled for known risk factors for the onset of chronic diseases, including demographic, psychosocial, and health risks. Discussion and Implications Findings reveal that physical health effects of disaster-related peritraumatic stress extend beyond the weeks and months after a disaster and include new onset of chronic diseases that are associated with loss of functioning and early mortality.

Are Love of Work, Perceived Organizational Support, and Psychological Well-Being Predictors of Work Engagement?

Job engagement is an essential factor in an organization because its ’ effect on individual and organizational performance is relatively large. Therefore, researchers need to understand the determinants of work engagement. This study aims to determine the relationship between love of work, perceived organizational support, and psychological well-being with work engagement. As many as 433 Polda Metrojaya police officers participated in this study. The participants came from all work units with a minimum service period of one year. The analysis technique used is multiple linear regression. Our findings reveal that love of work, perceived organizational support, and psychological well-being have a significant relationship with work engagement (R=.632), with the effective contribution of the three variables reaching 39.9%. This four measurement tools: The love of work perceived organizational support psychological well-being scale, and work engagement scale. Love for work is measured using the dimensions of love for work by Aulia (2019), which includes dimensions of zeal, emotional closeness, loyalty, and heartiness. The reliability coefficient of the love of work measuring instrument obtained is rtt 0.918. Furthermore, perceived organizational support is measured using the perceived organizational support scale by Aulia using dimensions from Rhoades and Eisenberg consisting of a sense of justice, superior support, and rewards from the organization and working conditions. The reliability coefficient for this measurement is rtt=0.9. Next is the measurement of psychological well-being variables using the dimensions of self-acceptance, positive relationships with others, independence, environmental mastery, life goals, and self-growth Rohimah The reliability coefficient of this measuring is rtt=0.913. Work engagement is measured using the Utrecht Work Engagement Scale (UWES) from Schaufeli & Bakker which has been modified by Aulia This measuring tool represents three measurement dimensions which include the dimensions of vigor, absorption, and dedication. The reliability coefficient of this modified UWES is rtt=0.850.
