A framework for understanding citizens' political participation in social media

Purpose The purpose of this paper is to explore how the use of social media by citizens has impacted the traditional conceptualization and operationalization of political participation in the society. Design/methodology/approach This study is based on Teorell et al.’s (2007) classification of political participation which is modified to suit the current context of social media. The authors classified 15,460 tweets along three parameters suggested in the framework with help of supervised text classification algorithms. Findings The analysis reveals that Activism is the most prominent form of political participation undertaken by people on Twitter. Other activities that were undertaken include Formal Political participation and Consumer participation. The analysis also reveals that identity of participant does not play a classifying role as expected from the theoretical framework. It was found that the social media as a platform facilitates new forms of participation which are not feasible offline. Research limitations/implications The current work considers only the microblogging platform of Twitter as the data source. For a more comprehensive insight, analysis of other social media platforms is also required. Originality/value To the best of the authors’ knowledge, this is one of the few analyses where such a large database covering multiple social media events has been created and analysed using supervised text classification algorithms. A large proportion of previous studies on social media have been based on case study and have limited analysis to only a particular event on social media. Although there exist a few works that have studied a vast and varied collection of social media data (Gaby and Caren, 2012; Shirazi, 2013; Rane and Salem, 2012), such efforts are few in number. This study aims to add to that stream of work where a wider and more generalized set of social media data is studied.
Effect of iron and zinc supplementation in the treatment of malaria in children

Iron and zinc administration for children with malaria in endemic area were known to decrease parasitemia but data on their effectiveness when given together to increase reticulocytes as erythropoiesis parameter and hemoglobin is insufficient. Objective To determine the effect of zinc to increase iron absorption in the treatment of Plasmodium falciparum malaria in children. Methods Children with positive Plasmodium falciparum on their blood smear (n=86) examination were randomly assigned to daily supplementation of iron 6 mg per kg body weight per day plus placebo or iron plus zinc 10 mg per day for 30 days. Venous blood specimens were collected at the start and at the end of the study. Results Sixty-nine children completed the supplementations and had both baseline and follow-up blood specimen study. After 30- day supplementation, the iron plus placebo and iron plus zinc groups showed significant difference on hemoglobin concentration (0.58 and 0.09 g/dl; P<0.05). There was no significant difference in reticulocyte production index and reticulocyte count before and after intervention in both groups. There was only significant difference in red blood cells concentration after supplementation of iron plus placebo and iron plus zinc (4.7 in 4.5 million/μl; P<0.05). Conclusions Iron supplementation with or without zinc shows significant increase of hemoglobin concentration. It is slightly higher in iron plus placebo group. (Paediatr Indones 2007; 47:256-260).
Specifics of communication skills in medicine

Communication in medicine is considered a core skill of the doctor on the way to successful diagnosis and treatment, and establishing an adequate relationship with the patient. In a similar way, should take place and the communication process between physician-patient and nurse - patient, and between all actors of the medical team and patients. Good communication skills, patience and sensitivity to the problems of the patient are necessary to create mutual trust. It is important to be in communication with the patient never imposing your own views, even when we are deeply convinced that whatever we do, we do it for their own good. Communication in health care requires knowledge, competence and technical skills, including the need for continuing active learning and practicing communication skills of all members of the medical team, both doctors and nurses and other staff who work with patients.
A deep learning approach for quality enhancement of surveillance video

Abstract The growing number of surveillance cameras imposes great demand on high efficiency video coding. Although modern video coding standards have significantly improved the video coding efficiency, they are designed for general video rather than surveillance video. The special characteristics of surveillance video leave a large space for further performance improvement. In this paper, we leverage a deep learning approach to enhance the quality of compressed surveillance video. More specifically, we formulate the problem of frame enhancement as a regression problem and design a Residual Squeeze-and-Excitation Network (RSE-Net), to address it. RSE-Net extensively exploits the non-linear mapping between the reconstructed frame and the ground truth, with only a small number of parameters. Moreover, By improving You Only Look Once (YOLO) network, we successfully detect the grouped vehicles within a frame. A novel model training scheme is then developed through learning from the grouped vehicles. With the proposed scheme, we train a global model for both foreground and background of surveillance video. Experimental results show that our method achieves average 0.40 dB, 0.22 dB and 0.24 dB PSNR gains over H.265/HEVC anchor in AI, LDP and RA configurations, and produces visually pleasing results when applied to compressed surveillance video.

Objectives: To assess the health of a group of employees from the nursing staff, who work in the fields of gynecology and obstetrics, surgical center, medical clinic and pediatrics, with respect to the signs and symptoms of Burnout Syndrome in a hospital in the state of Rio de Janeiro; to identify predicting factors for burnout syndrome, citing the somatic symptoms of burnout indicated by the research subjects and to present the three correlating factors present for burnout syndrome: emotional exhaustion, depersonalization, professional achievement. Method: Descriptive and quantitative approach, with 40 subjects, using the nursing staff of a hospital. A structured questionnaire was used, MBI (Maslach Burnout Inventory), with Likert scaling, given the period from April to May 2010. Results: Following the evaluation of the MBI, 55% (N = 22) had a low Burnout rate, 40% (N = 16) displayed an average rate, and 5% (N = 2) had a high rate. Conclusion: Burnout causes problems for the health care professional and also for the institution as a whole, as this syndrome is involved directly and indirectly in the cause of absenteeism, causing financial and organizational losses for the institution. Descriptors: Burnout, Occupational nursing, Occupational stress. RESUMO
Measurement-based V2V radio channel analysis and modelling for bridge scenarios at 5.9 GHz

In this study, vehicle-to-vehicle (V2V) radio channel measurements at 5.9 GHz were conducted on a suspension bridge and a beam bridge. Given that a different structure of the two bridges will result in different channel properties, the authors study small-scale and large-scale propagation characteristics for the bridge scenarios based on measurement data. By using Akaike's information criteria, the study determines optimal small-scale fading distribution. Owing to that Ricean distribution occupies the dominant position, Ricean K-factors in the two bridge scenarios are modelled separately and compared with each other. Afterwards, power delay profiles, Doppler power spectral densities, root-mean-square (RMS) delay spread and RMS Doppler spread are estimated and analysed in different cases. They employ bimodal Gaussian mixture distribution (BGMD) to model the RMS delay spreads and the RMS Doppler spreads. Fitting results of the BGMDs show good matching levels. For the large-scale propagation characteristics, path loss model for the beam bridge scenario is proposed based on the two-ray theory. On the other hand, path loss for the suspension bridge scenario is modelled by using an empirical function derived from WINNER II. Finally, grey relational grade–mean absolute percentage error, and RMS error criteria prove the effectiveness of the two proposed path loss models.
Integrated Coupled Inductors With Functionality of Current Balancing Transformer for Two-Phase Synchronous DC–DC Converters

With the emerging technology of wide-band-gap power semiconductors and modern ferrite materials, the switching frequency of dc–dc converters can be pushed to mega-hertz range to achieve higher power density. In order to deal with a high conduction current, multiphase converters are adopted to distribute the current for both power devices and windings. However, the current unbalance among phases may cause unexpected power loss to the converters. In this letter, the current unbalance issue is addressed by an integrated current balancing transformer for a two-phase dc–dc converter. The current of two phases in the converter can be automatically compensated to be identical by the proposed structure, which also reduces the complexity of the control system. A 1-MHz GaN-based two-phase buck converter is built to verify the proposed structure and its efficiency achieves 97.5% at 4 V/6 A output with the ZVS turn-on of the switches.

Control Strategies for Floating Offshore Wind Turbine: Challenges and Trends

The offshore wind resource has huge energy potential. However, wind turbine floating structures have to withstand harsh conditions. Strong wind and wave effects combine to generate vibrations, fatigue, and heavy loads on the structure and other elements of the wind turbine. These structural problems increase maintenance requirements and risk of failure, while reducing availability and energy production. Another challenge for wind energy is to reduce production costs in order to be competitive with other alternatives. From the control point of view, the objective of lowering costs can be achieved by operating the turbine close to its optimum point of operation under partial load, guaranteeing reliability by reducing structural loads and regulating the power generated in strong wind regimes. In this typical and challenging context, this paper proposes a critical state-of-the-art review, discussing challenges and trends on floating offshore wind turbines control.
Diabetes: A tale of two cultures

If this trend continues, one cannot help but predict future diabetes rates in the country not different from those seen in ethnic populations such as Pima Indians whereby nearly 50% of their adult population is dia-betic. We had predicted such an outcome many years ago and had urged the local community to take action against the rising tide of diabetes
Improved Model Predictive Control for High-Power Current-Source Rectifiers Under Normal and Distorted Grid Conditions

This article proposes an improved model predictive control (MPC) method for high-power current-source rectifiers (CSR). Instead of introducing the virtual impedance based active damping notion into MPC framework, the predefined cost function directly takes grid-side current and capacitor voltage as the regulating objectives to suppress the $LC$ resonance and grid current distortions. The relationship and differences between the proposed cost function and its form with active damping function are analyzed in detail under normal grid conditions. Moreover, the number of discrete candidate vectors during each predictive horizon in the proposed scheme is reduced from nine to five by considering the constraint of switching states transition. Therefore the computational burden is relieved compared with conventional MPC under normal grid conditions. Finally, in order to keep sinusoidal grid current for CSR even working under severe distorted supply voltage, specific harmonic orders of grid current suppression items are added into the proposed cost function subsequently. The performance of proposed methods at low switching frequency ($\leq$1 kHz) under normal and distorted grid conditions are tested through both simulation and experiments. For the implementation of all MPC methods, capacitor voltage is estimated by an observer to save hardware expense instead of using transducers.
Mood state and human evaluation of the thermal environment using virtual settings

Many complaints about indoor conditions are related to unsatisfactory thermal environments. Most research on thermal comfort (TC) considered physical parameters for settings and users yet marginalized the influence of user’s psychological aspects in the process of thermal sensation. Immersive virtual reality (VR) has been used in the built environment to simulate real scenarios. This research examines the effect of mood states on human evaluation of the thermal environment in virtual settings. Forty-four university students from Jordan participated. The experiment followed the ‘Experimental Design Method’ using thermally controlled chamber and TC evaluation using psychological responses developed by Fanger. The participants completed the PANAS-X pre-mood test before watching a video that targeted eliciting predetermined mood states: anger and happiness. The participants were then immersed in two virtual environments and asked to complete ASHRAE 7-point scale of TC. General Linear model was used to analyse the data. The results revealed a relationship between TC, mood state and quality of the indoor environment. Humans’ judgment on TC is a variable mental reaction. The research presents differences between the evaluation of angry and happy people to their thermal environments. This study expands research on the indoor environment quality and develops TC evaluation strategies.
MALADIE COELIAQUE : PARTICULARITÉS AFRICAINES A PROPOS DE 8 CAS À DJIBOUTI

La maladie coeliaque est meconnue en Afrique intertropicale. Nous en rapportons 8 observations colligees de facon retrospective entre janvier 2003 et janvier 2006, au Groupement Medico-Chirurgical Bouffard a Djibouti. Elles ont concerne 5 filles et 3 garcons dont l'âge varie de 9 mois a 17 ans (âge moyen : 48 mois), d'ethnie Somali 6 fois et Yemenite 2 fois, issus des classes moyennes de la population 6 fois et des classes les plus defavorisees 2 fois. Il s'agissait toujours de formes symptomatiques : alteration de l'etat general constante associee a des troubles digestifs (diarrhee ou vomissements). Le diagnostic a ete retenu dans ce contexte sur la presence d'anticorps anti-gliadine de type IgA et IgG, associes a des anticorps anti-endomysium ou anti-transglutaminase respectivement realises dans 75% et 25% des cas. Une endoscopie gastroduodenale realisee 3 fois avec biopsies duodenales a montre deux fois une atrophie villositaire totale associee a une augmentation de la lymphocytose intra epitheliale. Un regime sans gluten, instaure chez 5 malades, a entraine une reponse clinique favorable dans 4 cas avec un recul de 8,25 mois. La maladie coeliaque existe en Afrique intertropicale dans la region de la Corne de l'Afrique ou elle ne presente pas de particularite, en dehors de difficultes diagnostiques liees a une meconnaissance de l'affection et des moyens diagnostiques souvent insuffisants. La reponse favorable au regime sans gluten d'epreuve peut constituer une alternative diagnostique d'autant que ce regime parait moins astreignant a suivre a Djibouti qu'en occident en raison d'habitudes alimentaires differentes.
Novel sunflower MIMO fractal antenna with low mutual coupling and dual wide operating bands

Abstract A novel multiple-input and multiple-output (MIMO) fractal antenna excited by a coplanar waveguide was investigated in this study. A novel technique was used to improve the isolation of 20 dB between the dual radiating elements by inserting a strip line into the outer edges of the ground plane. A sunflower structure was used to configure the antenna in three steps. At each step, an additional sunflower structure was added with half the size of that used in the previous step to enhance the impedance bandwidth. The measured values of envelop correlation coefficient and total active reflection coefficient indicated that the proposed MIMO antenna has high-diversity performance between radiating elements. Wide dual operating bands of 2–2.9 and 5–10 GHz were obtained, which can support different wireless communications, such as 3G, LTE (2.6 GHz), WLAN (2.4 GHz/5 GHz), WiMAX (2.4 GHz/5GHz), ISM (2.4 GHz/5 GHz), 5G (5–6 GHz), and satellite communications (6–8 GHz). The MIMO fractal antenna with a small size achieved a maximum efficiency of 85% and a peak value gain of 6 dBi, low-channel capacity loss of 0.15–0.4 b/s/Hz, and high isolation between radiating elements is suitable for portable communication devices.
A High Voltage Gain DC–DC Converter Based on Three Winding Coupled Inductor and Voltage Multiplier Cell

This article introduces a single-switch, high step-up, dc–dc converter based on coupled-inductor with three winding and voltage multiplier cell to obtain a very high-voltage conversion ratio. A passive clamp circuit is applied in the converter to recycle the energy of leakage inductance and reduce voltage stress of the main power switch. This leads to utilize a power switch with low on-state resistance and low voltage rating that decreases the conduction losses. Several advantages include low operating duty cycle, high voltage conversion ratio, low turn ratio of the coupled inductor, leakage inductance reverse recovery, reduced voltage stress of semiconductors, alleviation of diodes reverse recovery issue and high efficiency, which make the presented topology appropriate for sustainable energy applications such as photovoltaic systems. The operation principle and steady-state analysis of the suggested topology in continuous conduction mode are expressed in detail. Also, design procedure and theoretical efficiency analysis of the proposed topology are presented. Moreover, a comparison study is performed to demonstrate the superiority of the presented converter over several similar recently proposed dc–dc converters. Finally, the proposed dc–dc converter feasibility and performance are justified through a fabricated 216-W laboratory prototype at 50 kHz switching frequency.
