‘Perverts’, ‘Terrorists’, and Business as Usual: Pether and Preventive Justice Scholarship
Authors: Tulich Tamara
Published: June 2018

In this article, I use the themes and arguments contained in Professor Penelope Pether’s unfinished monograph, ‘Perverts’, ‘Terrorists’, and Business as Usual: Comparative Indefinite Detention before and after 9/11, to reflect upon the emerging body of preventive justice scholarship. I argue that Pether’s account unsettles many of the assumptions and aspirations of preventive justice scholarship and highlights that preventive justice scholars, myself included, need to think differently about preventive justice – questioning its normative project and legal standpoint. I argue that preventive justice scholarship, while aiming to furnish the values and principles by which justice might be achieved, should be conscious of its potential role in the perpetration of injustice by legitimizing – or being used by others to legitimize – laws and practices that offend rights and liberties. In doing so, preventive justice scholarship can guard against complicity in what Pether terms ‘law’s…creation of jurisdictions of exception’.
Near infrared spectroscopy as an alternative method for rapid evaluation of toluene swell of natural rubber latex and its products
Authors: Lim Chin Hock , Sirisomboon Panmanas
Published: June 2018

Toluene swell or equilibrium swelling is universally used by rubber factories to measure the degree of crosslink of their compounded or prevulcanized latices at different stages of production. To apply near infrared spectroscopy for rapid and accurate quality control, spectral acquisition of prevulcanized latex, thin film and thick film was performed using a Fourier transform near infrared spectrometer in diffuse reflection mode across the wavenumber range of 12,500–3600 cm−1. For prevulcanized latex an effective model was developed using partial least squares regression with preprocessing (first derivative + straight line subtraction method). The coefficient of determination (r2), root mean square error of cross validation and bias of the validation set were 0.71, 3.93% and −0.005%, respectively. For the thin film model the r2, root mean square error of cross validation and bias were 0.65, 4.01% and −0.028%, respectively. Whereas for the thick film model the r2, root mean square error of cross validation and bias were 0.70, 4.00% and −0.006%, respectively. Three models including prevulcanized latex, thin film and thick film were validated by 23 unknown samples, providing standard error of prediction and bias of 5.357 and 2.494, 4.565 and 1.001 and 3.641 and −0.961%, respectively, for prevulcanized latex, thin film and thick film. The model developed for the thick film spectra gave the best results.

Published: June 2018

Objective:

Patients with hypertension tend to have a lower health-related quality of life (HRQOL) compared to normotensive patients. This study’s main objectives are to assess (1) HRQOL and factors that might impact it and (2) association between HRQOL and adherence to treatment, trust in physician, and treatment satisfaction among patients with hypertension.

Methods:

A cross-sectional study enrolled 196 patients from medical-care offices in Beirut, North and South Lebanon. Eligible patients signed a consent form and were asked to complete the Trust in Physician Scale, World Health Organization Quality of Life-brief (WHOQOL-brief) questionnaire, and Treatment Satisfaction Questionnaire (TSQM 1.4) as well as questions assessing medication adherence.

Results:

Better antihypertensive medication adherence was significantly and positively correlated with better HRQOL domains except general health where significance was not reached ( P = .089). Better adherence was also significantly related to better treatment satisfaction (side effects, convenience, and global satisfaction but not to effectiveness) and an increased trust in physicians ( P < .0001). Better treatment satisfaction (TSQM domains) was significantly and positively associated with a better overall HRQOL ( P ≤ .001). Increased trust in physician scores were significantly and positively correlated with a better psychological health, environment, and overall HRQOL domains ( P = .045, .005, and .006, respectively). Finally, TSQM effectiveness, convenience, and global satisfaction were significantly higher when trust in physician was greater ( P = .017, .035, and .002, respectively).

Conclusion:

The results of this study revealed an association between increased adherence to treatment, a higher global satisfaction, and an increased quality of life. An increased patient satisfaction with their antihypertensive treatment and trust in their physician were also correlated with a greater adherence to treatment.
Platelet Aggregation in Healthy Participants is Not Affected by Smoking, Drinking Coffee, Consuming a High-Fat Meal, or Performing Physical Exercise
Authors: Krekels Joyce P.M. , Verhezen Paul W.M. , Henskens Yvonne M.C.
Published: June 2018

Platelet aggregation can be measured using optical aggregation (light transmission aggregometry, LTA) as well as by impedance (Multiplate analyzer). The LTA (the gold standard method) can be influenced by many preanalytical variables. Several guidelines differ in recommendations for the duration patients should refrain from smoking, coffee, fatty meals, and physical exercise prior to blood collection for performing platelet function tests. In this pilot study, the influence of smoking, coffee, high-fat meal, or physical exercise on platelet aggregation was investigated to improve patient friendliness and laboratory logistics in platelet function diagnostics. Standardized blood collection was performed when participants were fasting and after each parameter (n=5 per group). As a control for diurnal fluctuations, participants (n=6) were fasting during both blood collections. Platelet aggregation was executed using standardized methods for LTA and Multiplate analyzer. Statistical analysis of the results using Wilcoxon signed-rank test did not show any significant differences in platelet aggregation in healthy participants under different preanalytical variables. Therefore, these variables are not expected to adversely affect testing, which can avoid canceling tests for those patients who inevitably did.
A biodegradable elastic stent model
Authors: Tambača Josip , Žugec Bojan
Published: June 2018

In this paper we derive and analyse a one-dimensional model of biodegradable elastic stents. The model is given as a nonlinear system of ordinary differential equations on a graph defined by the geometry of stent struts. The unknowns in the problem are the displacement of the middle curve of the struts, the infinitesimal rotation of the cross-sections of the stent struts, the contact couples and contact forces at struts and a function describing the degradation of the stent. The model is based on the one-dimensional model of a biodegradable elastic curved rod model by Tambača and Žugec (‘One-dimensional quasistatic model of biodegradable elastic curved rods’, Zeitschrift für Angewandte Mathematik und Physik 2015; 66(5): 2759–2785) and the ideas from the one-dimensional elastic stent modelling by Tambača et al. (‘Mathematical modeling of vascular stents’, SIAM Journal on Applied Mathematics 2010; 70(6): 1922–1952) used to formulate contact conditions at vertices. We prove the existence and uniqueness results for the model.

Respiratory exposure to multiwalled carbon nanotubes (MWCNT) or asbestos results in fibrosis; however, the mechanisms to reach this end point may be different. A previous study by our group identified pulmonary effects and significantly altered messenger RNA (mRNA) signaling pathways following exposure to 1, 10, 40, and 80 µg MWCNT and 120 µg crocidolite asbestos on mouse lungs over time at 1-month, 6-month, and 1-year postexposure following pulmonary aspiration. As a continuation to the above study, this current study took an in-depth look at the signaling pathways involved in fibrosis development at a single time point, 1 year, and exposure, 40 µg MWCNT, the lowest exposure at which fibrosis was pathologically evident. The 120 µg asbestos exposure was included to compare MWCNT-induced fibrosis with asbestos-induced fibrosis. A previously validated computational model was used to identify mRNAs with expression profiles matching the fibrosis pathology patterns from exposed mouse lungs. mRNAs that matched the pathology patterns were then input into ingenuity pathway analysis to determine potential signaling pathways and physiological disease functions inherent to MWCNT and asbestos exposure. Both MWCNT and asbestos exposure induced changes in mouse lungs regarding gene expression, cell proliferation, and survival, while MWCNT uniquely induced alterations in pathways involved in oxidative phosphorylation, mitochondrial dysfunction, and transcription. Asbestos exposure produced unique alterations in pathways involved in sustained inflammation. Although typically considered similar due to scale and fiber-like appearance, the different compositional properties inherent to either MWCNT or asbestos may play a role in their ability to induce fibrosis after pulmonary exposure.

Published: June 2018

Purpose:

To evaluate the outcome of second-line intravitreal ranibizumab treatment in eyes with diabetic macular edema having persistent edema following initial therapy with intravitreal bevacizumab.

Methods:

Diabetic macular edema treated with ranibizumab following bevacizumab failure in Israel was a retrospective, multi-center study. Consecutive eyes with persistent diabetic macular edema following at least three previous intravitreal bevacizumab injections prior to intravitreal ranibizumab, at least three-monthly intravitreal ranibizumab injections and at least 12 months of follow-up were included. Data collected included demographics, ocular findings, diabetes control, details of intravitreal bevacizumab and ranibizumab injections, and visual and anatomical measurements before and after intravitreal ranibizumab treatment.

Results:

In total, 202 eyes of 162 patients treated at 11 medical centers across Israel were included. Patients received a mean (±standard deviation) of 8.8 ± 4.9 intravitreal bevacizumab injections prior to the switch to intravitreal ranibizumab. A mean of 7.0 ± 2.7 intravitreal ranibizumab injections were given during the 12 months following the switch to intravitreal ranibizumab. The median central subfield retinal thickness (±interquartile range) by spectral-domain optical coherence tomography decreased from 436 ± 162 µm at baseline to 319 ± 113 µm at month 12 (p < 0.001). Median logMAR visual acuity (±interquartile range) improved from 0.40 ± 0.48 at baseline to 0.38 ± 0.40 at month 12 (p = 0.001). Linear regression suggested that higher number of intravitreal ranibizumab injections and higher pre-switch central subfield retinal thickness were associated with favorable visual outcome. Higher number of intravitreal bevacizumab injections and the presence of intraretinal fluid before the switch lessened the odds of favorable outcome.

Conclusion:

Switching from bevacizumab to ranibizumab in persistent diabetic macular edema was associated with anatomical improvement in the majority of eyes and ⩾2 lines of vision improvement in 22% of eyes.
Barriers and facilitators to participation in a health check for cardiometabolic diseases in primary care: A systematic review

Published: June 2018

Background

Health checks for cardiometabolic diseases could play a role in the identification of persons at high risk for disease. To improve the uptake of these health checks in primary care, we need to know what barriers and facilitators determine participation.

Methods

We used an iterative search strategy consisting of three steps: (a) identification of key-articles; (b) systematic literature search in PubMed, Medline and Embase based on keywords; (c) screening of titles and abstracts and subsequently full-text screening. We summarised the results into four categories: characteristics, attitudes, practical reasons and healthcare provider-related factors.

Results

Thirty-nine studies were included. Attitudes such as wanting to know of cardiometabolic disease risk, feeling responsible for, and concerns about one’s own health were facilitators for participation. Younger age, smoking, low education and attitudes such as not wanting to be, or being, worried about the outcome, low perceived severity or susceptibility, and negative attitude towards health checks or prevention in general were barriers. Furthermore, practical issues such as information and the ease of access to appointments could influence participation.

Conclusion

Barriers and facilitators to participation in health checks for cardiometabolic diseases were heterogeneous. Hence, it is not possible to develop a ‘one size fits all’ approach to maximise the uptake. For optimal implementation we suggest a multifactorial approach adapted to the national context with special attention to people who might be more difficult to reach. Increasing the uptake of health checks could contribute to identifying the people at risk to be able to start preventive interventions.
The Desired Managerial Leader Behavior: Leader Profile in the Education Sector in Iceland Examined From a Follower-Centric Perspective
Authors: Urboniene Lolita , Kristjánsdóttir Erla S. , Minelgaite Inga , Littrell Romie F.
Published: June 2018

This article presents a study of desired leadership behavior in the educational sector in Iceland. This sector has been undergoing major challenges during recent years, including restructuring and mergers of schools, strikes of teachers’ professional unions, and increasing dropout rates. This situation requires exceptional leadership together with the understanding that leadership is a culture and context contingent phenomenon. However, research on managerial leadership in the education sector in Iceland is virtually nonexistent, presenting a gap in literature as well as failure to contribute to solving issues in practice. This article contributes to closing this gap by investigating the desired leader profile from a follower-centric perspective. The results indicate that the most desired leader behaviors in this sector tend to be relationship orientated, suggesting a need to focus on the “soft” side of leadership and reconsider overemphasis on bureaucracy. Effects of gender and demographic differences are minimal, suggesting coherence with structural theory. Managerial leadership implications and future research directions are discussed.

Introduction:

Hysteroscopic management of juvenile cystic adenomyosis on a virgin patient with non-touch technique.

Description:

Juvenile cystic adenomyosis of uterus is a cyst which is surrounded by myometrium and inside of this cyst is filled with hemorrhagic fluid. A 23-year-old virgin patient admitted to endometriosis outpatient clinic. The patient complained of dysmenorrhea, chronic pelvic pain, and abnormal uterine bleeding. A submucosal adenomyotic cyst was, sized 40 mm approximately, determined at posterior wall of uterus by transrectal ultrasonography. She received daily 2 mg dienogest (Visanne®) for 6 months. At the end of 6 months of treatment, the cyst size was still 35 mm. Hysteroscopy was performed with the use of the non-touch technique (vaginoscopic approach). A rigid 2.9-mm hysteroscope with a 12° oblique lens and an outer sheath diameter of 4 mm was used. When the cystic wall was ruptured by bipolar instrument, a chocolate-colored fluid was drained. The operation lasted 10 min. Her postoperative course was uncomplicated. Postoperatively, two dose of leuprolide acetate 11.25 mg (Lucrin depot®—3M; Abbot, Istanbul, Turkey) was prescribed (6 months total). On her sixth month, there was no cyst on transrectal ultrasonography examination. The patient did not exhibit any symptoms.

Conclusions:

Because the disease affects adolescent girls, fertility issues should be kept in mind during the workup and when operating on these patients. Hysteroscopy is a mini-invasive, safe, and effective option for the treatment of juvenile cystic adenomyosis.
Japan–Iran Relations since the 2015 Iran Nuclear Deal
Authors: Nukii Mari
Published: June 2018

The US–Japan alliance has been one of the most important elements in configuring Japanese diplomacy since World War II. Accordingly, Japan’s relations with Iran always require striking a delicate balance among Japan’s security policy based on the US–Japan alliance, its energy demands, and its historically good bilateral relations with Iran. Japan welcomed the nuclear deal between Iran and the P5+1 group of nations in 2015. Iran holds the world’s second largest natural gas reserves and ranks fourth in proven crude oil reserves. Japanese companies were eager to re-enter the Iranian market with its rich natural resources and over 80 million strong population. However, the inauguration of President Trump in January 2017 and his antagonistic stance toward Iran has slowed this move. The Japanese government has taken the initiative to improve relations with Iran after lifting its sanctions against that country, while trying to mitigate possible risks. This article aims to examine relations between Iran and Japan after the Iran nuclear deal from three aspects: economic relations, nuclear cooperation, and security.

The occurrence of smectite-illite and smectite-chlorite minerals series was studied along a thick clay cap (~300 m) drilled in the Cerro Pabellón geothermal field (northern Andes, Chile). X-ray diffraction (XRD) and scanning electronic microscopy (SEM) were used to characterize the alteration mineralogy and clay mineral assemblages and their changes with depth. Cerro Pabellón is a high-enthalpy blind geothermal system, with a reservoir zone from ~500 m to 2000 m depth, with temperatures of 200–250°C. Three main hydrothermal alteration zones were identified: (1) argillic; (2) sub-propylitic, and (3) propylitic, with variable amounts of smectite, illite-smectite, chlorite-smectite, mixed-layer chlorite-corrensite, illite and chlorite appearing in the groundmass and filling amygdales and veinlets. Chemical and XRD data of smectites, I-S and illites show, with some exceptions, a progressive illitization with depth. The evolution of I-S with depth, shows a sigmoidal variation in the percentage of illite layers, with the conversion of smectite to R1 I-S at ~180–185°C. These temperatures are greater than those reported for other similar geothermal fields and might indicate, at least in part, the efficiency of the clay cap in terms of restricting the circulation of hydrothermal fluids in low-permeability rocks. Our results highlight the importance of a better understanding of clay-mineral evolution in active geothermal systems, not only as a direct (or indirect) way to control temperature evolution, but also as a control on permeability/porosity efficiency of the clay cap.

Published: June 2018

The article is devoted to actual problems of pedagogical support of personal and professional development of gifted students receiving legal education in the context of realization of the person-centered approach in modern Russian education. The analysis of various approaches to the definition of terms "giftedness", "talent" in the scientific literature was carried out. The article justifies the importance of the diagnostic activity of trainers to identify talented law students. The concept of "pedagogical support" as a basic one is considered. Attention is focused on the importance of the formation for gifted students-lawyers readiness to obtain professional knowledge for future practical activities, to constant professional self-development, skills of creative professional thinking, and communication skills. It is shown how the lecturer helps to form in this category of students emotional stability, high self-control behavior, the ability to reflective analysis, the ability to rationally get out of the conflict, adequate self-esteem and self-confidence. The article considers in details the directions of realization of pedagogical support for students-lawyers with outstanding creative and intellectual abilities and also suggests successive stages of realization of pedagogical support for gifted students at all training courses when obtaining a higher legal education.
Truthful Cheap Talk: Why Operational Flexibility May Lead to Truthful Communication
Authors: Berman Oded , Fazel-Zarandi Mohammad M. , Krass Dmitry
Published: June 2018

This paper shows that operational flexibility interacting with informational uncertainty may lead to truthful information exchange in equilibrium even when the communication is nonbinding and unverifiable, i.e., “cheap talk.” We consider a model consisting of a manufacturer releasing a new product with uncertain release date and demand, and a retailer who must determine the allocation of limited capacity between a preexisting third-party product and the manufacturer’s new product that may or may not be released on time. The manufacturer has a private forecast about the likelihood of the product release and/or about the demand, which he shares (either truthfully or not) with the retailer. We show that under the “traditional” supply chain structure (one-time opportunity to order) no truthful equilibrium can emerge. However, if (1) the supply chain structure allows for postponement, i.e., the ability to delay orders at a certain cost by the retailer, and (2) the manufacturer has informational uncertainty about the retailer’s capacity, then truthful information exchange may emerge in equilibrium, where the manufacturer transmits his true forecast and the retailer treats the transmission as truthful. The genesis of this effect is preference reversal, where the manufacturer is not sure which way to distort the forecast to best motivate the retailer to wait for the new product. Thus, we show that a truth-revealing mechanism can emerge from a relatively rich setup featuring two-sided information asymmetry interacting with postponement.

Macroeconomic Factors in Oil Futures Markets
Authors: Heath Davidson
Published: June 2018

This paper documents new evidence against perfect risk spanning in crude oil futures, and develops an affine futures pricing model that allows for unspanned macroeconomic factors. Compared to previous estimates, the oil spot premium is more volatile and strongly procyclical, which suggests that previous models miss the majority of variation in oil risk premiums. The estimates reveal a dynamic two-way relationship between oil futures and economic activity: productivity shocks are associated with higher oil prices, while oil price shocks affect economic activity by lowering future consumption spending. Unspanned macro factors also affect the valuation of real options.

Methodology to Investigate the Hydraulic Characteristics of a Water-Powered Piston-Type Proportional Injector Used for Agricultural Chemigation
Authors: Tang Pan , Li Hong , Issaka Zakaria , Chen Chao
Published: June 2018

Abstract.

The proportional injector is commonly used in agricultural chemigation due to its relatively high injection ratio. A major challenge with the proportional injector is related to its dependence on differential pressure, which is significantly influenced by changes in the viscosity, and setting injection ratio. A series of experiments were conducted to investigate the influence of differential pressures, solution viscosities, and setting injection ratios on the inlet and injection flow rates of a D25RE2 proportional injector. A mathematical model was developed to represent the hydraulic performance of this proportional injector. Finally, the mathematical model was verified using four different kinds of chemicals (humic acid, urea ammonium nitrate 32% N, fosthiazate, and colza oil). The inlet flow rate increased significantly with increasing differential pressure and decreased with increasing setting injection ratio. Results showed that the highest operating differential pressure should not be greater than 0.15 MPa for the D25RE2 proportional injector. The inlet flow rate gradually decreased with increasing viscosity, and a quadratic function relationship was derived between the inlet flow rate and the viscosity. The injection flow rate decreased with increasing viscosity. However, the viscosity had a slight influence on the injection flow rate when it was lower than 20 mPa·s. Mathematical models for calculating the inlet and injection flow rates with the influence of viscosity were developed, respectively. The coefficient of determination and the root mean square error (RMSE) for inlet flow rate calculation model were 0.8316 and 143.36 kg h-1, respectively. The coefficient of determination and the RMSE for the injection flow rate calculation model were 0.9706 and 0.9520 kg h-1, respectively. The calculating formula of inlet flow rate had a satisfactory accuracy under low differential pressure and high setting injection ratio. The calculating formula of the injection flow rate had a good accuracy, which is useful for calculating the injection flow rate when injected with different kinds of solutions. The average deviations between calculated and experimental injection flow rates with injection ratios of 0.2%, 1.2%, and 2% were obtained as 4.96%, 4.66%, and 4.1% respectively, which indicated that the average deviations decreased with increasing setting injection ratio. Results from this study are useful for both designers and users to effectively manage agricultural chemigation system with the proportional injector.

Satellite Psychrometric Formulation of the Operational Simplified Surface Energy Balance (SSEBop) Model for Quantifying and Mapping Evapotranspiration
Authors: Senay Gabriel   B
Published: June 2018

Abstract.

Remote sensing-based evapotranspiration (ET) can be derived using various methods, from soil moisture accounting to vegetation-index based approaches to simple and complex surface energy balance techniques. Due to the complexity of fully representing and parameterizing ET sub-processes, different models tend to diverge in their estimations. However, most models appear to provide reasonable estimations that can meet user requirements for seasonal water use estimation and drought monitoring. One such model is the Operational Simplified Surface Energy Balance (SSEBop). This study presents a formulation of the SSEBop model using the psychrometric principle for vapor pressure/relative humidity measurements where the “dry-bulb” and “wet-bulb” equivalent readings can be obtained from satellite-based land surface temperature estimates. The difference in temperature between the dry (desired location) and wet limit (reference value) is directly correlated to the soil-vegetation composite moisture status (surface humidity) and thus producing a fractional value (0-1) to scale the reference ET. The reference ET is independently calculated using available weather data through the standardized Penman-Monteith equation. Satellite Psychrometric Approach (SPA) explains the SSEBop model more effectively than the energy balance principle because SSEBop does not solve all terms of the surface energy balance such as sensible and ground-heat fluxes. The SPA explanation demonstrates the psychrometric constant for the air can be readily adapted to a comparable constant for the surface, thus allowing the creation of a “surface” psychrometric constant that is unique to a location and day-of-year. This new surface psychrometric constant simplifies the calculation and explanation of satellite-based ET for several applications in agriculture and hydrology. The SPA formulation of SSEBop was found to be an enhancement of the ET equation formulated in 1977 by pioneering researchers. With only two key parameters, improved model results can be obtained using a one-time calibration for any bias correction. The model can be set up quickly for routine monitoring and assessment of ET at landscape scales and beyond.

Effectiveness of Modified 1-Hour Air-Oven Moisture Methods for Determining Popcorn Moisture
Authors: Brabec Daniel , Perez-Fajardo Mayra , Dogan Hulya , Yeater Kathleen , Maghirang Elizabeth
Published: June 2018

Abstract

. Two of the most commonly used approved grain moisture air-oven reference methods for corn are the air oven method ASAE S352.2, which requires long heating time (72 h) at 103 ± 1°C for unground samples, and the AACC 44-15.02 air-oven method, which dries a ground sample for 1 h at 130 ± 1°C, but there is specific moisture measurement method for popcorn. The AACC 44-15.02 recommends a two-stage drying method for grain over 13%. But this involves more handling and drying time. The objective of this study was to develop an air-oven procedure for popcorn that requires short heating time (1h or less) based on existing reference method for ground corn (AACC 44-15.02). In the process of procedure development, two laboratory mills (Wiley Mini-Mill and Perten 3303 Mill) were optimized for mesh screen size and mill gap settings. The approved AACC method recommends using a 20-mesh screen fitted to the Wiley Mill, which failed, with wires breaking during the grinding process, possibly due to the hard nature of popcorn and/or clogging. It was replaced with the 10-mesh screen which produced larger particle size distribution with ~73% greater than 840 µm. The Perten Mill 3303 was set to gap No. 3 which produced ~68% particles that were greater than 840 µm. Additionally, this study evaluated the effectiveness of single-stage moisture measurement with the 14.5% and 16% moisture popcorn samples. Using the proposed procedure, four varieties of popcorn were tested at three different moisture contents (13%, 14.5%, and 16%). The method using the Wiley grinder and 60 min. heating time yielded oven moisture values which were statistically (p<0.05) similar to the approved ASAE S352.2 and AACC 44-15.02 (72-h, whole grain method). The moisture content of ground samples obtained from the Perten 3303 Mill had elevated moisture measurements and bias across the moisture levels when dried for 60 min. A reduction in heating time to 50 min. resulted in Perten mill samples yielding statistically (p<0.05) similar moisture measurements with the reference 72-h, whole grain method.

Seed Cotton Mass Flow Measurement in the Gin
Authors: Hardin IV Robert G.
Published: June 2018

Abstract. Seed cotton mass flow measurement is necessary for the development of improved gin process control systems that can increase gin efficiency and improve fiber quality. Previous studies led to the development of a seed cotton mass flow rate sensor based on the static pressure drop across the blowbox, which primarily results from acceleration of the seed cotton. The initial sensor did not perform satisfactorily in a gin, and modifications were made to account for air leakage through the rotary valve at the blowbox and the temperature drop occurring due to heat exchange between the seed cotton and air. Mass flow rate was predicted based on the static pressure differences across the blowbox and rotary valve, the air velocity and density at the blowbox inlet, the air density in the blowbox, and the ambient air density. The first- and second-stage seed cotton cleaning and drying systems of the commercial-scale gin at the Cotton Ginning Research Unit were instrumented to test the improved model. Air velocity, cultivar, dryer temperature, and seed cotton feed rate were varied to determine their effects on model accuracy. Mean absolute percentage errors in predicting mass flow rate were 3.89% and 2.85% for the first- and second-stage systems, respectively; however, dryer temperature had a significant effect on the regression coefficients. An additional regression parameter was added to the model to better estimate the average blowbox density, reducing the mean absolute percentage error to 2.5% for both systems and eliminating the effect of dryer temperature on the regression coefficients.

Authors: Liang Li-Fang
Published: June 2018

The myriad studies of migrant care workers adopt a rights perspective to address their liminal status and experience of exploitation. However, this perspective may fail to recognise the complexities of care and caring. Through describing the lived experiences of migrant live-in care workers and care recipients, this study illustrates the dynamics of care work and care relationships. It presents the complex dimensions of care work embedded in the intersections of labour, love, empathy, reciprocity, power and interdependency. A feminist ethics of care can be an alternative perspective in order to improve the well-being and interests of migrant care workers and care recipients.
Bullying, violencia entre iguales y Servicios Sociales. Un análisis desde la perspectiva de estudiantes de Criminología y Educación Primaria
Authors: Rodríguez Otero Luis Manuel , Gallego Jiménez Mª Gloria
Published: June 2018

El artículo presenta un estudio del bullying y de los Servicios Sociales. Dichos conceptos se describen a través de una investigación cualitativa tomando como contexto España con alumnado de Grado de Maestro de primaria y de Criminología. Se presenta una investigación cualitativa a partir del paradigma interpretativo y mediante un diseño basado en tres perspectivas teóricas: el constructivismo social, la teoría de la violencia y la teoría del estigma. Los resultados presentados confirman cómo el bullying hace referencia al tipo de violencia contextualizada dentro de la escuela y, los Servicios Sociales hacen referencia a la institución comunitaria que forma parte de la red de intervención de cualquier municipio o comarca. Es por ello que resulta de especial interés promover unas líneas básicas de prevención que favorezca entornos libres de violencia, elaborar programas específicos y coordinar el trabajo en la red comunitaria.

Authors: Lima Thales Batista de , Silva Joelma Ferreira da
Published: June 2018

A hospitalidade foi incorporada pela hotelaria e se tornou uma prática utilizada pelos hotéis para proporcionar atendimento diferenciado. Assim, o objetivo geral desta pesquisa é analizar a política de treinamento realizada por hotéis da capital paraibana para o desenvolvimento da hospitalidade. Desse modo, a fundamentação abordou os principais aspectos tipo, etapas, riscos e contribuições que envolvem treinamento, além da questão da hospitalidade e sua relevância no meio hoteleiro. Com relação à metodologia, utilizou-se a abordagem qualitativa, cujo método empregado foi o dedutivo e descritivo. Salienta-se que o estudo apresenta uma visão interpretativa dos dados. Dentre as principais constatações do estudo, observou-se que os treinamentos mais utilizados pelos hotéis são os de integração, comportamentais e técnicos, além disso, indica-se que a partir do treinamento, os gestores procuram pontuar a importância de tratar e receber bem os hóspedes. Quanto ao conhecimento dos gestores sobre o conceito de hospitalidade, percebeu-se que está relacionado ao ato do bem receber ou acolher. Portanto, conclui-se que os treinamentos aplicados pelos hotéis pesquisados contribuem para que a hospitalidade seja desenvolvida, resultando na melhoria do acolhimento dado aos hóspedes e, consequentemente, fazendo com que os empreendimentos ganhem destaque no cenário hoteleiro paraibano.

Encuestas preelectorales de las elecciones brasileñas de 2014: errores, aciertos y polémicas
Authors: G. Gramacho Wladimir
Published: June 2018

Este artículo se ocupa del análisis de encuestas preelectorales de las elecciones brasileñas de 2014, cuando estuvieron en juego los puestos de Presidente de la República y de los 27 Gobernadores de Estado. Si bien desde hace mucho no se cuestiona la fiabilidad de las votaciones en Brasil, existen crecientes quejas de diferentes actores políticos sobre la calidad y la posible influencia de las encuestas en los resultados electorales. El texto procura situar el debate tanto a nivel metodológico - al discutir diferentes alternativas para definir y mensurar los errores de las encuestas - como a nivel legislativo - al reunir informaciones sobre propuestas para limitar la acción de las empresas encuestadoras en períodos electorales.
Las elecciones de 2014 en Brasil: un análisis coyuntural del rendimiento de los partidos a nivel subnacional
Authors: Fernández Michelle , Carvalho Ernani , Rocha Enivaldo
Published: June 2018

A diferencia de lo que pasa en las elecciones a presidente en Brasil, donde PT y PSDB se alternan en la competencia por la silla presidencial, las elecciones subnacionales han enseñado a lo largo del tiempo un aspecto más diverso e, incluso, diferente de la dinámica política nacional. Por lo tanto, el presente artículo trata de dibujar el escenario y la dinámica de los partidos políticos en el contexto subnacional en Brasil en las últimas elecciones del pasado mes de octubre de 2014. Para eso, se va a analizar el resultado de las elecciones a gobernador de los estados y del distrito federal, además de observar la composición de las asambleas legislativas estaduales tomando el cuadro de los partidos como propuesta explicativa.
Pathologies osseuses des maxillaires récidivantes
Authors: Olszewski Raphael , Reychler Hervé
Published: June 2018

Plusieurs pathologies osseuses des maxillaires ont comme caractéristique une tendance à la récidive, et ce même après un traitement approprié. Il convient donc de les reconnaître afin de pouvoir les surveiller, à la fois cliniquement et par une technique d’imagerie appropriée. On distinguera ici des pathologies tumorales bénignes et malignes, métaboliques, malformatives et infectieuses. Actuellement, le CT scan est la technique d’imagerie médicale de premier choix pour établir le diagnostic différentiel et permettre la surveillance de ces pathologies osseuses. Le traitement de ces pathologies récidivantes est soit le curetage/énucléation si possible (corticales non rompues) soit une résection interruptrice ou non des maxillaires ou de la mandibule, et ce en fonction des données cliniques et surtout anatomopathologiques à discuter et envisager au cas par cas, la généralisation dans ce domaine étant impossible voire dangereuse pour le patient. Il ne peut donc être question de proposer des recommandations ni des algorithmes décisionnels.
Supporting and Mentoring New Social Work Instructors: A Formative Evaluation of the TEAM Program
Authors: Brady Shane R.
Published: June 2018

Abstract

            This study provides qualitative results from a unique mentorship and teaching support program designed, implemented, and evaluated in a school of social work at a major Midwestern research I university over a three year span. Primary qualitative data was collected through regular check-in meetings and end of the semester focus groups. Additional data was collected through orientation notes and detailed process notes from individual communications and consults with new instructors. Lessons learned point to both the importance of providing support and mentorship to new instructors as well as challenges in building and sustaining a positive culture for teaching and mentorship at a research I institution.
An Assessment of Group Size in Interteaching
Authors: Rosales Rocio , Soldner James L.
Published: June 2018

A key component of interteaching, as described by Boyce and Hineline (2002), is the opportunity for students to participate in "dyadic" or pair discussions. Although the rationale for pair discussions is evident, only one study to date has evaluated the relative effectiveness of student performance when group size is manipulated. The present investigation was designed to further evaluate the effect of group size during pair discussions on student quiz scores in an introductory psychology course with a diverse group of learners. An alternating treatments design was implemented whereby students were assigned to work in a dyad or in groups of 4-5 students to discuss a preparation guide. All of the major components of interteaching were in effect during both conditions (i.e., availability of prep guides and quality points, clarifying lectures, and frequent test probes). Results showed a small advantage for performance following discussion in dyads, although a social validity measure indicated students favored discussion in larger groups. Implications of these findings and suggestions for future work will be discussed.
Technological Innovation or Educational Evolution? A Multi-disciplinary Qualitative Inquiry into Active Learning Classrooms
Authors: Gordy Xiaoshan Zhu , Jones Ellen M , Bailey Jessica H
Published: June 2018

In recent years, many institutions have transformed traditional classrooms (TCs) into technology-rich active learning classrooms (ALCs) to accommodate the pedagogical concept of “active learning”. In order to investigate the impact of ALCs on teaching and teaching, we observed an instructor teaching in an ALC for an entire academic year, audio/video-recorded every class and took field notes. A focus group discussion was conducted with faculty from six allied health disciplines who taught weekly classes in the ALC and an online survey was distributed to students who took those classes. Data was then analysed using a qualitative constant comparative method (CCM). Findings indicated that the ALC generated greater teaching and learning enjoyment, deepened engagement, amplified interaction, enhanced group activity efficiency and fostered the development of creative ideas.  All these features were interrelated and created a synergistic effect on student learning.
A Hybrid High-Order Method for Highly Oscillatory Elliptic Problems
Authors: Cicuttin Matteo , Ern Alexandre , Lemaire Simon
Published: June 2018

We devise a Hybrid High-Order (HHO) method for highly oscillatory elliptic problems that is capable of handling general meshes. The method hinges on discrete unknowns that are polynomials attached to the faces and cells of a coarse mesh; those attached to the cells can be eliminated locally using static condensation. The main building ingredient is a reconstruction operator, local to each coarse cell, that maps onto a fine-scale space spanned by oscillatory basis functions.
The present HHO method generalizes the ideas of some existing multiscale approaches, while providing the first complete analysis on general meshes. It also improves on those methods, taking advantage of the flexibility granted by the HHO framework. The method handles arbitrary orders of approximation
