Published: December 2019

Aim of study: Main objective of this research was to predict some of the processes (soil loss, runoff and sediment yield) related to soil erosion with the help of WEPP (Water Erosion Prediction Project) model.
Area of study: The WEPP model was applied to the Düz Creek Watershed (1059 ha in size). It is a sub-watershed flowing into the greater Çoruh River Basin near the district of Borçka, Artvin.
Material and methods: As required by the WEPP model, four large-data files of soil, climate, slope and plant cover/management were created for the watershed using the data gathered from in-field samplings (soil), laboratory analyses and GIS (Geographical Information Systems) assessments. For easier run and detailed investigation of soil erosion process of the research area, the studied watershed was divided into eight small hydrological units (SHUs) and the program was run on these SHUs.
Main results: At the end of GeoWEPP’s run, the results revealed that a total of about 735 mm annual precipitation was fell within the study area. The model also predicted that there was approximately 207 mm as runoff out of this amount of precipitation, which, in turn, generated an annual total soil loss and sediment amounts as 2815.2 t and 2720.9 t, respectively. In addition, the sediment yield per unit area was estimated to be around 2.57 ton/ha/yr while the sediment delivery ratio (SDR) was found to be as 0.977. Lastly, the model predicted that the particle distribution of eroded sediment were 20%, 25% and 55% of clay, silt and sand, respectively, while the mean organic matter (OM) amount of the lost sediment was about 5% for the studied watershed.
Highlights: Soil loss and sediment yield can be calculated for large areas in a short time and with little cost.

Business travel decisions and high-speed trains: an ordered logit approach
Authors: Rossi Federica , Maggi Rico 
Published: December 2019

The paper studies the potential impact on business travel of the new high-speed railway line project, called AlpTransit, which will link Lugano, the small economic hub of the southern part of Switzerland, with Zurich, one of the major Swiss economic centres, situated north of the Alps. Thanks to this infrastructure, travel time between the two cities will decrease considerably from about three hours to less than two hours by the end of 2020.
The question that we pose in this paper is what impact high-speed trains could have, in the short to medium term, on business travel between the two hubs (ex-ante evaluation). Indeed, given the travel time, firms could increase their business-to-business one-day trips, boosting face-to-face interactions within and among enterprises. Our curiosity more specifically regards the potential impact of the change in travel time on the propensity to travel of employees with different functions in various types of firms.
An on-line survey was conducted among firms located in Ticino, the Swiss Canton that includes Lugano. The data are analysed using four ordered logit models, one for each employee category (CEO, administrative staff, sales personnel, specialists), since hierarchical position and professional status influence business travel characteristics. Results show that internal firm characteristics, such as sector, frequency and destination of current business travels significantly influence the propensity to travel to Zurich more often thanks to AlpTransit.

Authors: Golkhandan Abolghasem 
Published: December 2019

Background: Many previous empirical studies indicated appropriate implementation of the fiscal decentralization and transfer of resources and expenses from the central government to local governments was an important factor to improve health outcomes in developing countries. Accordingly, the major purpose of this study was to evaluate the impact of fiscal decentralization indicators on the mortality rate (as an indicators of health measurement) in Iranian provinces.
Methods: This study uses the statistical data of variables affecting the mortality rate in provinces of Iran to study the spatial effects of fiscal decentralization indicators on the mortality rate during 2006-2015. To this end, the spatial econometric approach was used. Furthermore, the statistical analyses were performed using the Matlab software.
Results: Findings of the model's estimation indicate that indicators of the fiscal decentralization and mortality rate had a negative and significant relationship. In this regard, 1 % increase in fiscal decentralization indicators of income and expenditure decreased the mortality rate by 0.19 % and 0.10 % in provinces of Iran, respectively. Other results showed that the spatial proximity effect between provinces of Iran had a positive and significant effect on the mortality rate.
Conclusion: By providing the necessary conditions for expansion of fiscal decentralization, the health level can be promoted in provinces of Iran.

Background: The optimal management of hospitals as the most important centers for providing health services has always been the focus of decision makers and policymakers. The present study aimed to evaluate the technical efficiency of hospitals affiliated to Ardebil University of Medical Sciences using Artificial Neural Network (ANN) method.
Methods: The present descriptive, applied, and cross-sectional study was conducted in 2017. The study population consisted of 8 educational and therapeutic centers affiliated to Ardabil University of Medical Sciences and Health Services. Census sampling method was applied to select the participants and researcher-made checklists were used to collect the data. The artificial neural network method was also used to investigate the study objectives. The applied network was a multi-layer prospectron with a Levenberg Marquardt optimization function, a sigmoid tangent transfer function in the middle layer, and a linear function in the output layer. For processing and preparing data, Excel spreadsheet was used and Matlab software were used for analyzing and designing the network.
Results: The results showed that the average technical efficiency of the studied hospitals was 0.75. Ardabil Bou Ali, Khalkhal Imam Khomeini, and Meshkinshahr Valiasr hospitals had the highest technical efficiency (1.00). With regard to the hospital bed occupancy rate, Germi Velayat hospital had the lowest efficiency rate (0.75). Furthermore, Parsabad Imam Khomeini hospital had the lowest efficiency in the number of discharged healthy patients (0.69) in 2017. Finally, the improvement space of each variable was calculated to achieve the total technical efficiency.
Conclusion: According to the results, one of the factors that decreases the technical efficiency of the educational centers is the low rate of hospital beds' utilization and occupancy rate. In other words, lack of full-capacity operation by the hospital centers and the low rates of active hospital bed imposed costs and consequently reduced the hospitals' performance.

La filière laitière occupe une place importante à l’échelle mondiale, en termes de contribution à l’occupation des surfaces agricoles, aux emplois et à la création de richesse. La production laitière, qui résulte de modèles productifs très variés d’un pays à l’autre et qui relève d’espèces animales aux caractéristiques différentes, a considérablement augmenté au cours des dernières décennies. Le développement futur de la production laitière est soumis à différentes contraintes qui interrogent sur les voies à privilégier dans une optique de durabilité. Dans ce cadre, la première partie de cet article présente la dynamique du secteur laitier, en termes de consommation et de production, et ce, pour différentes grandes zones géographiques ; la seconde traite de la durabilité du secteur laitier, principalement dans les pays en développement, au travers d’une sélection de trois thèmes : la dimension sociale (souvent oubliée) et la nécessité d’intégrer les questions de genre ; l’usage durable des ressources hydriques en l’illustrant au travers de deux situations contrastées, celle du Maroc et de l’Inde ; la biodiversité et l’importance de la contribution des laits non bovins au développement local. La troisième partie rappelle que les échanges internationaux permettent, pour de nombreux pays déficitaires en lait, de satisfaire la demande intérieure.

Le déclenchement de l’ovulation peut se faire selon deux modes chez les mammifères : spontané et provoqué. L’ovulation spontanée intervient au cours du cycle œstral sous l’effet de facteurs internes hormonaux. L’ovulation provoquée est déclenchée par l’accouplement avec un mâle. Dans les deux cas, c’est une augmentation de la sécrétion de GnRH qui conduit à l’augmentation de LH qui provoque l’ovulation. Les facteurs qui conduisent à l’augmentation de sécrétion de GnRH sont différents selon les deux modalités : principalement la kisspeptine (ovulation spontanée) et le b-NGF (ovulation provoquée). Les protocoles d’induction de l’ovulation actuels reposent sur une action directe sur l’ovaire, grâce à l’utilisation de gonadotropines hétérologues, ou bien par une action sur l’hypophyse grâce aux agonistes du GnRH. Ces protocoles présentent différents inconvénients : perte d’efficacité dans le temps, stimulation supra-physiologique qui peut être délétère, problème éthique posé par l’obtention de certaines molécules. De nouveaux paradigmes d’induction de l’ovulation ciblant l’hypothalamus, et favorisant un déclenchement physiologique de l’ovulation sans supplémentation en hormones sont en cours de développement. Cette revue a pour objectif de présenter au lecteur les mécanismes intimes impliqués dans la régulation et le déclenchement de l’ovulation ainsi que deux approches nouvelles respectueuses de la physiologie de l’animal et de l’environnement.

Abstract
Background
A large number of students at a school in Guangzhou city developed a sudden onset of symptoms of diarrhea and vomiting. To help control the outbreak, we conducted an epidemiological investigation to determine the causative agent, sources, role of transmission and risk factors of the infections.
Methods
The study population consisted of probable and confirmed cases. An active search was conducted for cases among all students, teachers and other school staff members. A case control study was carried out using standardized online questionnaires. Data were obtained regarding demographic characteristics, gastrointestinal symptoms, personal hygiene habits, history of contact with a person who had diarrhea and/or vomiting and dining locations during the past 3 days. Rectal swabs or stool samples of the cases and, food handlers, as well as environmental samples were collected to detect potential intestinal viruses and bacteria. We calculated odds ratios and 95% confidence intervals (CIs).
Results
A total of 157 individuals fit the definition of a probable case, including 46 with laboratory-confirmed norovirus infection between March 8 and March 22, 2018. The proportion of students who had eaten delivery food 3 days before the onset of illness in the case group was 2.69 times that in the control group (95% CI: 1.88-3.85 ). Intake of take-out food 3 days earlier, and exposure to similar cases 72 hours before onset and case in the same dormitory were risk factors. A total of 20 rectal swab samples from students, 10 rectal swabs from food handlers and 2 environmental swab samples from the out-campus restauranttested positive for norovirus (G Ⅱ , genogroup Ⅱ strain ).
Conclusions
We investigated an outbreak of norovirus infectious diarrhea. Food handling practices carry potential risk of acute gastroenteritis outbreaks owing to a lack of surveillance and supervision. Greater attention should be paid to the monitoring and supervision of food handlers in off campus restaurant to reduce the incidence of norovirus-related acute gastroenteritis associated with delivery food.
