Extending the Models of Employee Turnover to Include External Drivers such as Client-related Factors: A Multi-country, Qualitative Assessment
Authors: Radford Katrina , Stephenson Amber L.
Published: November 2019

The employee turnover literature to date is teeming with process models that assume only organizational and personal factors contribute to employees’ intentions to leave and stay. However, with the average percentage variance explained still only around 50%, it is clear that other factors play a substantial role in these decision-making processes. One possible explanation is to explore the unique role that clients play in employees’ intentions to stay or leave. This paper extends the conceptualization of the role that clients play on employee’s intentions to stay and leave their roles, particularly within service industries such as health care. This paper presents the results of two qualitative studies that examine employees’ decision-making process for turnover and retention intentions. The first study explores the factors influencing employees’ intentions to stay and leave the Australian aged care sector (N = 420) and the second study explores prison health care nurses in the United States (N = 175). The results of both studies reveal that client-related factors affect the choice to stay within a job and, in some cases, are the favoured aspect of the role. Therefore encouraging client-staff relationships will expand job satisfaction and therefore increase retention of employees within both contexts.

Published: November 2019

Evaluasi merupakan kesatuan sistem manajemen baik itu perencanaan, pelaksanaan, maupun monitoring. Bendung merupakan salah satu dari sekian banyak aset negara yang seringkali dilakukan evaluasi guna mengetahui kondisi asset tersebut. Evaluasi tingkat pelayanan Bendung Tomatoppe dilakukan untuk mengetahui tingkat pelayanan Daerah Irigasi Bajo dengan membandingkan tingkat pelayanan rencana atau desain awal pada tahun 2009/2010 dan tingkat pelayanan pada tahun 2016 dan 2018. Di Sulawesi Selatan tepatnya Kecamatan Bajo Kabupaten Luwu sebagian besar mayoritas penduduknya merupakan petani, untuk menjamin ketersediaan air di daerah mereka pada tahun 2010 Pemerintah Pusat telah melakukan membangun Bendung Tomatoppe yang berpotensi mengaliri lahan persawahan sebesar 5.829 Ha yang tersebar di beberapa Kecamatan. Prosedur evaluasi dilakukan dengan pengamatan dan pengambilan debit pada saluran primer, sekunder dan tersier terpilih guna mengetahui perbedaan debit rencana dan debit evaluasi. Hasil penelitian menunjukkan pelayanan Bendung Tomatoppe pada tingkat luas tanam dengan jumlah maksimum sebesar 5.691 Ha. Hal ini berbeda dengan rencana awal pembangunan pada tahun 2009 sebesar 5.829 ha. Perubahan nilai debit penelitian dengan dengan debit rencana dapat di sebabkan oleh beberapa faktor yaitu adanya proses sedimentasi, kehilangan air irigasi yang di sebabkan oleh penguapan (evaporasi), serta adanya perubahan desain awal terhadap saluran dan luas area layanan.

Escrituras más allá de las palabras: vocabulario “islámico” en las primeras traducciones árabes de la Biblia
Authors: HJÄLM Miriam L.
Published: November 2019

Este artículo discute el uso de vocabulario “islámico” en traducciones árabes de la Biblia, compuestas en torno al siglo IX. El artículo sugiere la existencia de un vínculo entre dicho uso y la dependencia y función de la traducción Vorlage, y de la traducción técnica general atestiguada en ella. El artículo además propone que una función de las traducciones, que contienen un uso aparentemente notable y deliberado del vocabulario de sonido islámico, fue mostrar que las Escrituras cristianas podían absorber el mensaje del Islam, al igual que los primeros teólogos cristianos árabes promulgaron la idea de que los dogmas cristianos calaron en El Corán. Por lo tanto, en lugar de proteger sus Escrituras de una religión competidora, vistiéndolas en un registro lingüístico más neutral, estos traductores y autores presentaron un cristianismo esencialmente elevado más allá de las palabras y los contextos y por lo tanto representable en cualquiera de ellos.

Published: November 2019

Milling is of important process to improve nutritional and palatability of sorghum seeds for human consumption. This study investigated the effect of milling process on protein fraction of sorghum flour and the bran. The result showed that dry milled sorghum flour contained higher protein than those of wet milled sorghum flour, and the highest protein content was found on sorghum bran.  Dry-milled sorghum flour has protein fraction in albumin, globulin, kafirin and glutelin higher than those of wet-milled sorghum flour. Wet-millled sorghum flour contained high protein fraction in cross link kafirin and cross link glutelin.  Different of protein fractions noticed among the samples suggested that the samples contained different in amount of extractable protein and this was due to the differences in total protein.

Published: November 2019

There is a substantial amount of literature dealing with many aspects of synthesis and characterization of pure and doped binary compounds including Mn-doped ZnO which has been widely studied due to its superb properties as a dilute magnetic semiconductor (DMS).Aspects concerning doping limits for these compounds is an important stage in the search for new materials. Samples of Zn1-xMnxO nanocrystal were synthesized at temperatures of 180 °C and 200 °C using wet or liquid phase synthesis method. Dopant concentrations x=0.5, 1, 1.5, 2, 2.5, 5, 10, 20, 30, 40 and 50 per cent were studied. Powder x-ray diffraction (PXRD) patterns of the samples were analyzed with a view to determining the onset of secondary phases and hence the solubility limit of the dopant. The solubility limit for Mn in ZnO samples synthesized at temperature of 200 °C is realized at x <20%. For samples synthesized at temperature of 180 °C, the solubility limit is x <0.5%.
Quenching the Kitaev honeycomb model
Authors: Rademaker Louk
Published: November 2019

I studied the non-equilibrium response of an initial Néel state under
time evolution with the Kitaev honeycomb model. With isotropic
interactions (J_x = J_y = J_zJx=Jy=Jz)
the system quickly loses its antiferromagnetic order and crosses over
into a steady state valence bond solid, which can be inferred from the
long-range dimer correlations. There is no signature of a dynamical
phase transition. Upon including anisotropy
(J_x = J_y \neq J_zJx=Jy≠Jz),
an exponentially long prethermal regime appears with persistent
magnetization oscillations whose period derives from an effective toric
code.

A educação rural concebida por Renato Sêneca Fleury em meados da década de 1930
Authors: Celeste Filho Macioniro
Published: November 2019

O artigo estuda a concepção de educação rural formulada por Renato Sêneca Fleury em meados da década de 1930. Este autor de vasta obra didática não via contradições entre a educação escolarizada no campo e os princípios de educação ativa da Escola Nova. Assim, a sua abordagem constitui-se como possibilidade interpretativa de uma Escola Nova rural. É objetivo do atual estudo compreender como formulações educacionais envolvendo o homem do campo tiveram em Renato Fleury uma concepção alternativa para a educação rural brasileira. Os procedimentos metodológicos utilizados privilegiaram a análise de sua principal obra teórica sobre o tema, o livro Educação rural, de 1936. Com propósitos ilustrativos, o artigo exemplifica como isto ocorreu em partes do instrumento de letramento publicado por ele em 1935, o livro Na roça: cartilha rural para alfabetização rápida. Os textos de outros autores que estudaram a produção de Renato Fleury subsidiaram a análise aqui executada.
Convolutional Neural Network Visualization for Identification of Risk Genes in Bipolar Disorder
Authors: Yue Qixuan , Yang Jie , Shu Qian , Bai Mingze , Shu Kunxian
Published: November 2019

Background :

Bipolar disorder (BD) is a type of chronic emotional disorder
with a complex genetic structure. However, its genetic molecular mechanism is still
unclear, which makes it insufficient to be diagnosed and treated.

Methods and Results:

In this paper, we proposed a model for predicting BD based on
single nucleotide polymorphisms (SNPs) screening by genome-wide association study
(GWAS), which was constructed by a convolutional neural network (CNN) that predicted
the probability of the disease. According to the difference of GWAS threshold, two sets
of data were named: group P001 and group P005. And different convolutional neural
networks are set for the two sets of data. The training accuracy of the model trained with
group P001 data is 96%, and the test accuracy is 91%. The training accuracy of the
model trained with group P005 data is 94.5%, and the test accuracy is 92%. At the same
time, we used gradient weighted class activation mapping (Grad-CAM) to interpret the
prediction model, indirectly to identify high-risk SNPs of BD. In the end, we compared
these high-risk SNPs with human gene annotation information.

Conclusion:

The model prediction results of the group P001 yielded 137 risk genes, of
which 22 were reported to be associated with the occurrence of BD. The model
prediction results of the group P005 yielded 407 risk genes, of which 51 were reported to
be associated with the occurrence of BD.
The Association Between Keratoconus and Mitral Valve Prolapse: A Meta-Analysis
Authors: Siordia Juan A. , Franco Jimena C.
Published: November 2019

Objective:

The debate pertaining to the association between Keratoconus (KC) and Mitral Valve Prolapse (MVP) continues to occur among physicians. The results of cross-sectional studies attempting to present the co-existing prevalence of these two diseases remain indeterminate. We compiled the first meta-analysis to determine the pattern of prevalence between the two diseases.

Methods:

Two separate literature searches for cross-sectional studies were performed for this metaanalysis. The first search encompassed finding literature comparing the prevalence of KC between patients with MVP and a control group. The second search pertained to finding studies comparing the prevalence of MVP patients with KC and a control group.

Results:

Six studies reported the prevalence of MVP in patients with KC and a control group. The prevalence was 41.6% in patients with KC and 11.5% in patients without KC (OR = 7.06 [95% CI = 2.41-20.64]). There was a significant heterogeneity among the studies (I2 = 84%). Two studies showed the prevalence of KC in patients with MVP and a control group. The prevalence was 17.0% in patients with KC and 2.9% in the control group (OR = 5.07 [95% CI = 1.08-23.83]). There was no heterogeneity within the analysis (I2 = 0%).

Conclusion:

There is a statistically significant co-existing prevalence between MVP and KC. Patients with KC are more likely to present with MVP, and patients with MVP are more likely to present with KC.

use. Subsequently, imidazole constitutes a new class of compounds for new drug development as the
presence of this nucleus in diverse therapeutic categories viz; antimicrobial, anti-inflammatory, anticancer,
immunomodulator, antiviral etc. has made it an interesting moiety for the design and development
of new pharmacological agents. Thus, this review aims to summarize the reported molecular
entities which were synthesized by using conventional as well as microwave processes, chemistry
and biological potential of imidazole containing heterocyclic molecules while identifying potential
areas of further research on imidazole.

Results:

The review comprises literature pertaining to the evidence-based pharmacological or therapeutic
potential of imidazole using published articles and worldwide databases. Various pharmacological
experiments using different models exclusively proved the potential of imidazole.

Focusing on the discovery and development of new imidazole nucleus based molecules
at a faster rate, there is a need to search previous information available in the market in the field of
medicinal chemistry. Therefore, the present review aims to elaborate the therapeutic worth of imidazole
and its analogs.

Published: November 2019

Background

Weight loss interventions using mobile phone apps have recently shown promising results.

Objective

This study aimed to analyze the short-term weight loss effect of a mobile coaching intervention when it is integrated with a local public health care center and a regional hospital’s antiobesity clinic as a multidisciplinary model.

Methods

A total of 150 overweight or obese adults signed up to complete an 8-week antiobesity intervention program with human coaching through a mobile platform. Paired t tests and multiple linear regression analysis were used to identify the intervention factors related to weight change.

Results

Among the 150 participants enrolled in this study, 112 completed the 8-week weight loss intervention. Weight (baseline: mean 77.5 kg, SD 12.9; after intervention: mean 74.8 kg, SD 12.6; mean difference −2.73 kg), body mass index, waist circumference, fat mass (baseline: mean 28.3 kg, SD 6.6; after intervention: mean 25.7 kg, SD 6.3; mean difference −2.65 kg), and fat percentage all showed a statistically significant decrease, and metabolic equivalent of task (MET) showed a statistically significant increase after intervention. In multiple linear regression analysis, age (beta=.07; P=.06), △MET (beta=−.0009; P=.10), number of articles read (beta=−.01; P=.04), and frequency of weight records (beta=−.05; P=.10; R2=0.4843) were identified as significant factors of weight change. Moreover, age (beta=.06; P=.03), sex (female; beta=1.16; P=.08), △MET (beta=−.0009; P<.001), and number of articles read (beta=−.02; P<.001; R2=0.3728) were identified as significant variables of fat mass change.

Conclusions

The multidisciplinary approach, combining a mobile health (mHealth) care app by health care providers, was effective for short-term weight loss. Additional studies are needed to evaluate the efficacy of mHealth care apps in obesity treatment.
Lifestyle Disease Surveillance Using Population Search Behavior: Feasibility Study
Authors: Memon Shahan Ali , Razak Saquib , Weber Ingmar
Published: November 2019

Background

As the process of producing official health statistics for lifestyle diseases is slow, researchers have explored using Web search data as a proxy for lifestyle disease surveillance. Existing studies, however, are prone to at least one of the following issues: ad-hoc keyword selection, overfitting, insufficient predictive evaluation, lack of generalization, and failure to compare against trivial baselines.

Objective

The aims of this study were to (1) employ a corrective approach improving previous methods; (2) study the key limitations in using Google Trends for lifestyle disease surveillance; and (3) test the generalizability of our methodology to other countries beyond the United States.

Methods

For each of the target variables (diabetes, obesity, and exercise), prevalence rates were collected. After a rigorous keyword selection process, data from Google Trends were collected. These data were denormalized to form spatio-temporal indices. L1-regularized regression models were trained to predict prevalence rates from denormalized Google Trends indices. Models were tested on a held-out set and compared against baselines from the literature as well as a trivial last year equals this year baseline. A similar analysis was done using a multivariate spatio-temporal model where the previous year’s prevalence was included as a covariate. This model was modified to create a time-lagged regression analysis framework. Finally, a hierarchical time-lagged multivariate spatio-temporal model was created to account for subnational trends in the data. The model trained on US data was, then, applied in a transfer learning framework to Canada.

Results

In the US context, our proposed models beat the performances of the prior work, as well as the trivial baselines. In terms of the mean absolute error (MAE), the best of our proposed models yields 24% improvement (0.72-0.55; P<.001) for diabetes; 18% improvement (1.20-0.99; P=.001) for obesity, and 34% improvement (2.89-1.95; P<.001) for exercise. Our proposed across-country transfer learning framework also shows promising results with an average Spearman and Pearson correlation of 0.70 for diabetes and 0.90 and 0.91 for obesity, respectively.

Conclusions

Although our proposed models beat the baselines, we find the modeling of lifestyle diseases to be a challenging problem, one that requires an abundance of data as well as creative modeling strategies. In doing so, this study shows a low-to-moderate validity of Google Trends in the context of lifestyle disease surveillance, even when applying novel corrective approaches, including a proposed denormalization scheme. We envision qualitative analyses to be a more practical use of Google Trends in the context of lifestyle disease surveillance. For the quantitative analyses, the highest utility of using Google Trends is in the context of transfer learning where low-resource countries could benefit from high-resource countries by using proxy models.
Web Comparison of Three Contingent Valuation Techniques in Women of Childbearing Age: The Case of Ovulation Induction in Quebec
Authors: Dieng Aissata , He Jie , Poder Thomas G
Published: November 2019

Background

In Canada, 11.5% to 15.7% of couples suffer from infertility. Anovulation, or failed ovulation, is one of the main causes of infertility in women. In Quebec, the treatment for ovulation induction and other services related to assisted reproductive technology (ART) have been partially reimbursed by the government since 2010.

Objective

This study aimed to compare the willingness to pay (WTP) of women of childbearing age to receive drug treatment in the event of failed ovulation according to 3 different contingent valuation methods.

Methods

The following elicitation techniques were used: simple bid price dichotomous choice (DC), followed by an open-ended question (DC-OE), and a simplified multiple-bounded discrete choice (MBDC). Each participant was randomly assigned to 1 of 3 elicitation techniques. Bid prices ranged from Can $200 to Can $5000. Of the 7 bid prices, 1 was randomly proposed to each participant in the DC and DC-OE groups. For the DC-OE group, if the answer to the DC bid price was no, respondents were asked what was the maximum amount they were willing to pay. For the MBDC group, each respondent was offered an initial bid price of Can $1500, and the subsequent bid price offer increased or decreased according to the answer provided. “Do not know” responses were considered as a “no”, and each individual was questioned as to their certainty after each choice. WTP values were estimated using probit and bivariate models; the Welsh and Poe model was also performed for the MBDC group.

Results

The survey was conducted from 2009 to 2010 with a total sample of 680 women. Analyses were performed on 610 respondents (199 DC, 230 DC-OE, and 181 MBDC). Of the 70 respondents who were excluded, 6 did not meet the age criterion, 45 had an annual income less than Can $2500, and 19 did not respond to the WTP question. Mean WTP values were Can $4033.26, Can $1857.90, and Can $1630.63 for DC, DC-OE, and MBDC, respectively. The WTP for MBDC “definitely yes” and “probably yes” values were Can $1516.73 and Can $1871.22, respectively. The 3 elicitation techniques provided WTP value differences that were statistically significant (P<.01). The MBDC was the most accurate method, with a lower confidence interval (Can $557) and a lower (CI/mean) ratio (0.34).

Conclusions

A positive WTP for ovulation induction was found in Quebec. Adding a follow-up question resulted in more accurate WTP values. The MBDC technique provided a more accurate estimate of the WTP with a smaller and, therefore, more efficient confidence interval. To help decision making and improve the effectiveness of the fiscal policy related to the ART program, the WTP value elicited with the MBDC technique should be used.

This paper will discuss the perspectives of the marine medicine in the Crimean region, outlining key achievements from the collaboration between the Medical Academy Named after S. I. Georgievsky (Simferopol) and Sanatorium Sudak. As a result integral diagnostic approach of navy military personnel was provided by the research team ensuring that early most physical and psychic functional changes are revealed in time. Given approach with the main focus on most efficient measures is aimed to provide person-oriented rehabilitation techniques in terms of health resort accounting for the specific professional activity. Current research consists of a series of examinations made in accordance with the standardized methods for the functional state examination followed by the medical and psychological rehabilitation recommended by the Ministry of Defense of the Russian Federation as well as own approaches were applied for the assessment of adaptive responses. At this stage examination of the submarines’ crew members that was carried out during the entire health resort rehabilitation period suggests that for differentiation approach to be successful the assessments should consider the condition of the autonomic nervous system and highly sensitive parameters of the electroencephalographic recordings. As comparison of current standards and recommendations of medical and psychological rehabilitation with the efficiency of electroencephalography and heart rate variability recordings along with the psychological tests suggests that the latter provide better insights into the efficiency of rehabilitation and they should be included into the examination protocols. Assessment and further appropriate correction of microelement status should be also implemented as it ensures better functional and adaptive capacity.
