Unobserved heterogeneity across the travelers should be taken into consideration to prevent biasedness and inconsistency in the estimated parameters in the stop frequency models. Additionally, previous studies on the stop frequency have mostly been done in larger metropolitan areas and less attention has been paid to the areas with less population. This study addresses these gaps by using 2012 travel data from a medium sized U.S. urban area using the work tour for the case study. Stop in the work tour were classified into three groups of outbound leg, work based subtour, and inbound leg of the commutes. Latent Class Poisson Regression Models were used to analyze the data. The results indicate the presence of heterogeneity across the commuters. Using latent class models significantly improves the predictive power of the models compared to regular one class Poisson regression models. In contrast to one class Poisson models, gender becomes insignificant in predicting the number of tours when unobserved heterogeneity is accounted for. The commuters are associated with increased stops on their work based subtour when the employment density of service-related occupations increases in their work zone, but employment density of retail employment does not significantly contribute to the stop making likelihood of the commuters. Additionally, an increase in the number of work tours was associated with fewer stops on the inbound leg of the commute. The results of this study suggest the consideration of unobserved heterogeneity in the stop frequency models and help transportation agencies and policy makers make better inferences from such models.展开更多

Many studies' subjects are concentrated on the higher learning institutions. However, few of them are concerned about application-oriented university students' ICC. So the behavior and role of students' ICC in the overseas study tours in 2016 and 2017 in one of the application-oriented universities in Zhejiang province becomes the main focus. It exams from three aspects: intercultural attitudes, knowledge and behaviors. Basically, students benefit a lot from study tours, especially in the aspect of practical communication, among which, they change from shy, inexperienced learners to be brave, confident, and skilled in the tours. Also, considering the problems of host school are existed, the suggestions proposed by participants that practical courses of destination countries had better be arranged for students to understand and adapt to it beforehand. Besides, more communication and interactions between students and teachers should be increased to create a more active and relaxed classroom atmosphere, which contribute to mobilize students' initiative and enthusiasm to better become a complementary influence to promote students' ICC.展开更多

The aim of our study was to study the epidemiological, clinical and etiological aspects of hepatomegaly in the hepato-gastroenterology department (HGE) of the Gabriel Touré university hospital. This was a cross-sectional study that took place from September 2021 to October 2022 in the department. All patients aged 18 years and older with hepatomegaly, hospitalized or examined by physicians were included. We collected 100 cases of hepatomegaly, representing 3.7% of 2661 patients examined or hospitalized in the HGE department during the study period. These patients had a mean age was 46.7 ± 16.10 years with extremes of 18 and 76 years. The sex ratio was 2.7. Jaundice was the most commonly reported history with a frequency of 26%. Pertaining to patients’ lifestyle, alcohol consumption was the most common feature with 6%. The most common associated clinical signs were jaundice, ascites, and edema of the lower limbs. Painful hepatomegaly (86%), with a sharp lower edge (74%), a firm consistency (69%), and an irregular surface (52%) was frequently observed. Cytolysis (75.5%), increased alphafetoprotein levels (70%), microcytic anemia (37%), hyperleukocytosis (54.3%), and biological hepatocellular insufficiency syndrome (low albumin with 30.4%, high bilirubinemia with 61.2% and low platelets with 33.9%) were the most common observed laboratory abnormalities. Hepatitis B virus markers (61%) were the most frequently found in the study patients. At ultrasound examination, heterogeneous hepatomegaly was observed in 87.3% of the patients. Esophageal varices (43.1%) were more commonly seen than other varices during upper gastrointestinal endoscopy. The dominant etiology was hepatocellular carcinoma on cirrhosis with 66% followed by cirrhosis. Conclusion: Painful hepatomegaly was quite frequently in our urban setting hospital with several etiologies. HCC was the most common etiology, therefore measures to prevent it in the community need to be established by the concerned stakeholders to improve adult population health in Bamako.展开更多

A formulation of the problem based on vehicle indices is proposed in the form of a mixed integer linear program (MILP). The mathematical model of the problem is solved using a branch and cut (B&C) algorithm. The results of the tests are compared to the results of a branch and price (B&P) algorithm from the literature on 2E-IRP with a classical distribution policy. The results of the tests show that the B&C algorithm solves 197 out of 200 instances (98.5%). The comparison of the B&C and B&P results shows that 185 best solutions are obtained with the B&C algorithm on 197 instances (93.9%). Overall, the B&C algorithm achieves cost reductions ranging from 0.26% to 41.44% compared to the classic 2E-IRP results solved with the B&P algorithm, with an overall average reduction of 18.08%.展开更多
