O perfeccionismo direcionado à aparência física considera haver preocupação com a imperfeição e esperança para a perfeição em relação à aparência. O objetivo dessa pesquisa foi validar a versão em português Brasileiro da Physical Appearance Perfectionism Scale em uma amostra de praticantes de exercícios resistidos. A amostra não-probabilística foi constituída por 534 homens e mulheres com idades entre 18 a 39 anos. Foi utilizadaanálise fatorial confirmatória, para gerar evidencias psicométricas para a amostra de referencia. O modelo estrutural bifatorial alcançou índices de ajuste satisfatório, tanto na amostra geral, quanto na amostra por sexo. Em relação à validade convergente, quase todos os valores das cargas fatoriais estavam acima do aceitável, mas a variância média extraída foi adequada apenas na escala masculina. Quanto à validade discriminante, todos os valores da AVE estiveram acima do valor da variância compartilhada nos modelo geral, feminino e masculino, demonstrando haver alguma diferença as duas variáveis latentes. A confiabilidade de constructo foi estabelecida tanto na escala geral, quanto na escala feminina e masculina. O presente instrumento obteve evidencias psicométricas adequadas para a versão brasileira da Physical Appearance Perfectionism Scale, o que permite recomendar seu uso no Brasil.
Perfectionism towards physical appearance considers to be concern about imperfection and hope for perfection in appearance. The aim of this research was to validate the Brazilian Portuguese version of Physical Appearance Perfectionism Scale in a sample of exercise resistance practitioners. The non-probabilistic sample consisted of 534 men and women aged 18 to 39 years. Confirmatory factorial analysis was used to generate psychometric evidence for the reference sample. The two-factor structural model achieved satisfactory adjustment indices, both in the general sample and in the sample by sex. Regarding convergent validity, almost all values of factorial loads were above acceptable, although the average variance extracted (AVE) was adequate only in the male scale. Regarding the discriminant validity, all the AVE values were above the value of the shared variance in the general model, female and male, showing that there are some differences between the two latent variables. Construct reliability was established on both the general scale and the female and male scale. This instrument achieved adequate psychometric evidence for the Brazilian version of Physical Appearance Perfectionism Scale, which allows recommending its use in Brazil.
Organizational development with torture rehabilitation programs
Authors: Rendahl Kristi , Kriege Santoso Pamela 
Published: January 2020

Torture rehabilitation has emerged as a field over the past several decades and much of the literature has focused on clinical interventions, related evaluation, and documentation of torture. Less discussed are organizational development initiatives that seek to strengthen organizational effectiveness in order to improve mental health outcomes for torture survivors. Based on applied experience in organizational development with torture rehabilitation programs in post-conflict contexts, the authors explore key organizational development needs in the field of torture rehabilitation, areas of future consideration for international agency donors, and additional future considerations for torture rehabilitation programs themselves. A case is made fo organizational development efforts that prioritize time for strategic thinking that includes participation from stakeholders across the organization’s functions; staff care policies that prevent secondary trauma and promote wellbeing and retention; clarity surrounding organizational structure and roles; financial management systems that position the organization for growth and fund diversification strategies beyond the project-based international agency funding model. The work requires longterm commitment in terms of technical and subgrant assistance, including an ongoing process of assessing and adjusting approaches. The case examples included are representative of certain key challenges that may be addressed to some degree within the parameters of a similar project. While the work of torture rehabilitation is urgent by nature, the authors emphasize the need for practical approaches for the important (but not urgent) work of organizational development.

Aims: The lower susceptibility of the Fulani to malaria compared to Mossi was previously described in Burkina Faso in West Africa. The mature gametocyte stage of Plasmodium falciparum is known to be the only stage capable of infecting the mosquito though this process is disrupted by the action of immunity and other factors as well. Our study aims to assess the ability of two sympatric ethnic groups known to have different susceptibility to Plasmodium falciparum malaria, to infect mosquitoes through an experimental membrane feeding assay.
Methodology: Study participants were gametocyte carriers aged from 2 to 12 years recruited in the village of Barkoundouba where Fulani and Mossi are living in sympatric. A venous blood was obtained from each participant for direct membrane feeding assay of insectary reared mosquitoes. Blood fed mosquitoes were stored for 7 days with sugar water as the only food source, then dissected for the microscopic detection for oocysts.
Results: A total of 1050 mosquitoes were used for the experimental infections. Eight day after feeding, a total of 897 mosquitoes were dissected, 275 from the Fulani and 622 from the Mossi group. With an average of 43 stomachs examined by experimentation, the mosquito infestation rate was 10.5% in Fulani and 13.2% in Mossi group (p=0.569). The fed mosquito rate was 95 % and 95.6% in Fulani and Mossi ethnic group respectively (p=0.241). The rate of survival mosquitoes after the feeding was 96.5% and 87.5% in Fulani and Mossi ethnic group respectively (p=0.088). The proportion of dissected mosquitoes was 100% and 99.2% in Fulani and Mossi ethnic group respectively (p=0.138) leading to an average oocystic load of 249 in Fulani and 21 in Mossi group. The success rate of DMFA in both groups combined was 57.14%. Indeed, this rate was 33.33% and 66.67% in Fulani and Mossi group respectively.
Conclusion: Our study showed that there is no significant difference found between the two ethnic group with the fed, survival, dissected and the infested mosquitoes rate. However, the average of oocystic load was higher in Fulani than the Mossi group despite the low infection in Fulani group. There is a need to explore the mechanism underlying such difference between the two ethnic groups.

Aims: The study was aimed to investigate the effect coloured polythene bags on fruit quality of ‘Himsagar’ mango grown in New Alluvial Zone of West Bengal, India.
Methodology: Field experiment was conducted at Regional Research Station, New Alluvial Zone, Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, India (22°56″ N, 88°31″ E and 9.75 m above mean sea level) during the period from 2017 to 2018. The experiment was laid out in completely randomized block design (RBD) having six distinct bagging treatments (T1- Blue polythene bag, T2- Green polythene bag, T3- Yellow polythene bag, T4-Red polythene bag, T5- White polythene bag, and one control i.e. T6- No bag), replicated four times. Fruit physical parameters, bio-chemical parameters, physiological loss in weight and disease incidence % at different days of storage were analyzed in this experiment.
Results: Experimental findings showed that among different colour of bags, green colour (T2) proved most effective as most physical parameters and bio-chemical constituents of fruit were improved in this treatment. Fruits at 8 days storage at ambient room temperature showed maximum total soluble solids, total sugar and β-carotene content with the application of green colour bag. This treatment also exhibited less physiological loss in weight (PLW) with minimum incidences of post harvest diseases during storage at ambient room temperature.
Conclusion: Findings from this study show that fruit bagging with green polythene bag proved most effective in increasing the fruit weight and bio-chemical constituents of mango with less incidence of diseases that ultimately leading to better consumer acceptance and gives higher return to the growers.

Published: January 2020

The constituents of wastes generated from abattoir activities create conducive environment for microbial proliferation, most of which are pathogenic. Infections caused by these microorganisms could result to zoonoses. This study was to determine the distribution of bacterial isolates and their biomass from different abattoirs in Port Harcourt. Samples like waste blood, table swab, service water, faecal matter, soil and wastewater from abattoirs in Iwofe, Rumuodomaya and Trans-Amadi were collected from October 2017 to November, 2018 and analysed using standard microbiological procedures. Results obtained revealed that the total heterotrophic bacterial count of blood samples ranged from 8.33x101 to 3.33x102 cfu/ml for Trans-Amadi and Iwofe abattoirs, table swabs ranged from 6.74x104 to 4.88x106 cfu/ml, water samples ranged from 1.56x104 to 2.07x104 cfu/ml; faecal matter had THB counts ranging from 9.97x107 to 1.06x108 cfu/g; and soil samples ranged from 1.11x1010 to 1.17x1010 g, while wastewater counts ranged from 1.03x108 to 1.08x108 cfu/ml. The predominant Bacterial isolates were of the genera Micrococcus, Staphylococcus, Serratia, Pseudomonas, Proteus, Klebsiella, Escherichia and Chromobacterium, Serratia sp. only was isolated from Iwofe and Rumuodomaya abattoirs within April to October while Chromobacterium sp. was isolated in Trans-Amadi and Rumuodomaya abattoirs within the months of May to October. Among the isolates, Escherichia coli and Klebsiella species occurred more compared to others in all the three locations. A higher percentage of microorganisms were recorded in the month of May compared to other months. It is presumed that abattoir wastes harbour many microorganisms of public health importance. The occurrence of these microbes, most of which are enteric pathogens, poses a public health challenge as infections by them could result in illnesses such as gastroenteritis, septicaemia and pneumonia especially in the absence of good hygiene around abattoirs. Proper sanitation in abattoirs as well as management of abattoir wastes is important in reducing the spread of these microorganisms.

Published: January 2020

AbstractPurposeTreatment planning system (TPS) dose calculation is sensitive to multileaf collimator (MLC) modeling, especially when treating with intensity‐modulated radiation therapy (IMRT) or VMAT. This study investigates the dosimetric impact of the MLC leaf‐tip model in a commercial TPS (RayStation v.6.1). The detectability of modeling errors was assessed through both measurements with an anthropomorphic head‐and‐neck phantom and patient‐specific IMRT QA using a 3D diode array.Methods and MaterialsAn Agility MLC (Elekta Inc.) was commissioned in RayStation. Nine IMRT and VMAT plans were optimized to treat the head‐and‐neck phantom from the Imaging and Radiation Oncology Core Houston branch (IROC‐H). Dose distributions for each plan were re‐calculated on 27 beam models, varying leaf‐tip width (2.0, 4.5, and 6.5 mm) and leaf‐tip offset (−2.0 to +2.0 mm) values. Doses were compared to phantom TLD measurements. Patient‐specific IMRT QA was performed, and receiver‐operating characteristic (ROC) analysis was performed to determine the detectability of modeling errors.ResultsDose calculations were very sensitive to leaf‐tip offset values. Offsets of ±1.0 mm resulted in dose differences up to 10% and 15% in the PTV and spinal cord TLDs respectively. Offsets of ±2.0 mm caused dose deviations up to 50% in the spinal cord TLD. Patient‐specific IMRT QA could not reliably detect these deviations, with an ROC area under the curve (AUC) value of 0.537 for a ±1.0 mm change in leaf‐tip offset, corresponding to >7% dose deviation. Leaf‐tip width had a modest dosimetric impact with <2% and 5.6% differences in the PTV and spinal cord TLDs respectively.ConclusionsSmall changes in the MLC leaf‐tip offset in this TPS model can cause large changes in the calculated dose for IMRT and VMAT plans that are difficult to identify through either dose curves or standard patient‐specific IMRT QA. These results may, in part, explain the reported high failure rate of IROC‐H phantom tests.

ObjectiveTo evaluate the association between adherence to antimalarials and type 2 diabetes mellitus (DM) in patients with systemic lupus erythematosus (SLE).MethodsUsing administrative health databases in British Columbia, Canada, we conducted a retrospective, longitudinal cohort study of patients with incident SLE and incident antimalarial use. We established antimalarial drug courses by defining a new course when a 90‐day gap is exceeded between refills and we calculated proportion of days covered (PDC) for each course. We categorized medication taking as: 1) adherent (PDC ≥0.90), 2) nonadherent (0 < PDC < 0.90), and 3) discontinuer (no drug). Type 2 DM outcomes were based on outpatient or inpatient visits, or antidiabetic medication use. We used multivariable Cox proportional hazards models with time‐dependent variables.ResultsOver a median of 4.62 years of follow‐up in our incident cohort of 1,498 patients with SLE (90.8% women), we recorded 140 incident cases of type 2 DM. Multivariable hazard ratios were 0.61 (95% confidence interval [95% CI] 0.40–0.93) for adherent and 0.78 (95% CI 0.50–1.22) for nonadherent, respectively, as compared to discontinuers.ConclusionOur findings of a protective effect of adherence to antimalarials in preventing type 2 DM provides further support for the importance of adherence to antimalarials to obtain the benefits of therapy.

ObjectiveTo assess the relation of symptomatic knee osteoarthritis (OA), knee pain, and radiographic knee OA to All‐cause mortality and to identify mediators in the causal pathway.MethodsParticipants from the Osteoarthritis Initiative were divided into 4 groups: 1) symptomatic knee OA (i.e., both radiographic knee OA [Kellgren/Lawrence grade ≥2] and knee pain); 2) knee pain only; 3) radiographic knee OA only; and 4) neither radiographic knee OA nor knee pain. We examined the relation of knee OA status to All‐cause mortality using a multivariable Cox proportional hazards model and assessed the extent to which the association was mediated by disability, physical component summary (PCS) and mental component summary (MCS) scores for quality of life (QoL), and use of oral pain‐relief medications (i.e., nonsteroidal antiinflammatory drugs and opioids).ResultsAmong 4,796 participants, 282 died over the 96‐month follow‐up period. Compared with those with neither radiographic knee OA nor knee pain, multivariable‐adjusted hazard ratios (HRs) of mortality were 2.2 (95% confidence interval [95% CI] 1.6–3.1) for symptomatic knee OA, 0.9 (95% CI 0.6–1.4) for knee pain only, and 2.0 (95% CI 1.4–2.9) for radiographic knee OA only, respectively. Indirect effects (HRs) of symptomatic knee OA on mortality via disability and PCS of QoL were 1.1 (95% CI 1.0–1.4) and 1.2 (95% CI 1.0–1.4), respectively. No apparent mediation effect was observed through either MCS of QoL or oral pain‐relief medications use.ConclusionParticipants with either symptomatic or radiographic knee OA were at an increased risk of All‐cause mortality. Increased risk of mortality from symptomatic knee OA was partially mediated through its effect on disability and PCS of QoL.

AbstractSpatial electromagnetic (EM) radiation, big data, is both an opportunity and a challenge. Harvesting and converting waste EM energy for high‐efficient recycling has a huge significance in the energy field. Herein, a new and effective patching engineering method using conductive polymers to repair magnetic graphene (NF‐P) is proposed, tailoring the microstructure network controllably, including conductive network and relaxation genes. It realizes the precise tuning of EM property, and the EM response shows a significant increase of 52%. The energy transformation inside materials is surveyed, and a revolutionary mode of energy conversion is constructed, ingeniously utilizing the stored electrical energy and the converted heat energy inside the material with the theoretical utilization of absorbed EM energy up to 100%. The NF‐P patching network serves as a prototype for a potential cell device with the EM energy conversion improved by ≈10 times and effective bandwidth increased by 13 GHz that covers the entire research frequency band (2–18 GHz). This research opens up a new idea for energy utilization inside materials, providing a novel and effective path for harvesting, converting and delivering spatial EM energy.

AbstractRechargeable sodium‐ion batteries (SIBs) are considered attractive alternatives to lithium‐ion batteries for next‐generation sustainable and large‐scale electrochemical energy storage. Organic sodium‐ion batteries (OSIBs) using environmentally benign organic materials as electrodes, which demonstrate high energy/power density and good structural designability, have recently attracted great attention. Nevertheless, the practical applications and popularization of OSIBs are generally restricted by the intrinsic disadvantages related to organic electrodes, such as their low conductivity, poor stability, and high solubility in electrolytes. Here, the latest research progress with regard to electrode materials of OSIBs, ranging from small molecules to organic polymers, is systematically reviewed, with the main focus on the molecular structure design/modification, the electrochemical behavior, and the corresponding charge‐storage mechanism. Particularly, the challenges faced by OSIBs and the effective design strategies are comprehensively summarized from three aspects: function‐oriented molecular design, micromorphology regulation, and construction of organic–inorganic composites. Finally, the perspectives and opportunities in the research of organic electrode materials are discussed.

AbstractFire retardant coatings have been proven effective at reducing the heat release rate (HRR) of structural materials during burning; yet effective methods for increasing the ignition temperature and delay time prior to burning are rarely reported. Herein, a strong, fire‐resistant wood structural material is developed by combining a densification treatment with an anisotropic thermally conductive flame‐retardant coating of hexagonal boron nitride (h‐BN) nanosheets to produce BN‐densified wood. The thermal management properties created by the BN coating provide fast, in‐plane thermal diffusion, slowing the conduction of heat through the densified wood, which improves the material's ignition properties. Compared with densified wood without the BN coating, a 41 °C enhancement in ignition temperature (Tig), a twofold increase in ignition delay time (tig), and a 25% decrease in the maximum HRR of BN‐densified wood can be achieved. As a proof of concept for scalability, the pieces of the BN‐densified wood are fabricated with a length larger than 25 cm, width greater than 15 cm, and thickness more than 7 mm. The improved thermal management, fire resistance, mechanical strength, and scalable production of BN‐densified wood position it as a promising structural material for safe and energy‐efficient buildings.

Published: January 2020

AbstractRational design of unique pre‐catalysts for highly active catalysts toward catalyzing the oxygen evolution reaction (OER) is a great challenge. Herein, a Co‐derived pre‐catalyst that allows gradual exposure of CoOOH that acts as the active center for OER catalysis is obtained by both phosphate ion surface functionalization and Mo inner doping. The obtained catalyst reveals an excellent OER activity with a low overpotential of 265 mV at a current density of 10 mA cm−2 and good durability in alkaline electrolyte, which is comparable to the majority of Co‐based OER catalysts. Specifically, the surface functionalization produces lots of Co‐PO4 species with oxygen vacancies which can trigger the surface self‐reconstruction of pre‐catalyst for a favorable OER reaction. Density functional theory calculations reveal that the Mo doping optimizes adsorption‐free energy of *OOH formation and thus accelerates intrinsic electrocatalytic activity. Expanding on these explorations, a series of transition metal oxide pre‐catalysts are obtained using this general design strategy. The work offers a fundamental understanding toward the correlation among surface‐structure‐activity for the pre‐catalyst design.
