It suggests that demographic homophily between a customer and a service provider has a positive effect on trust, thereby leading to customer loyalty. There is also a mediating effect regarding the clarity of communication and a moderating effect of cultural background on the relationship between demographic homophily and trust. This cross-cultural study compares Korean and German consumers. The moderated mediation effects by cultural background were investigated based on PROCESS, and the mediation effect of trust turned out to be significantly moderated by cultural background. Regardless of cultural background, demographic homophily turned out to be an important explanative variable for building trust with medical service providers. By investigating the significance of demographic homophily and the impact of cultural background, this research contributes to the service marketing field, both academically and practically.","PeriodicalId":17054,"journal":{"name":"Journal of Software Maintenance and Evolution: Research and Practice","volume":"28 1","pages":"130-142"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84270722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyses are based on data of the 2018 BIBB/BAuA Employment Survey, a representative sample of the German labour force. The three service sectors trading, finance, and public services varied significantly in how leaders perceive job demands, job resources, psychosomatic health complaints, and musculoskeletal health complaints. Hardly any variation was found, however, in how demands and resources are associated with psychosomatic and musculoskeletal health complaints. These findings imply that service leaders’ perceptions provide sector-specific patterns of demands and resources, which are well reflected in stress theory. The findings further imply that there is no need for sector-specific theories predicting health complaints. The article concludes with a discussion of practical implications for health promotion in the three service sectors and the promotion of leaders’ health.","PeriodicalId":17054,"journal":{"name":"Journal of Software Maintenance and Evolution: Research and Practice","volume":"50 1","pages":"103-118"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81774560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the effect of sarcopenia on the incidence of postoperative complications in patients who underwent resection interventions on the pancreas, as well as the development of a simple clinical diagnosis of sarcopenia. Material and methods. Th e study included 109 patients, including 59 (54.1 %) men and 50 (45.9 %) women. All patients included in the study were operated on with subsequent morphological examination of the removed preparations. Diagnosis of the presence of sarcopenia in a patient was carried out using computed tomography (CT) and calculating the musculoskeletal index. Also, all patients underwent calculation of the psoas major muscle index (IBPM) equal to the ratio of the area of the psoas major muscle on one side to the square of the patient’s height. Th e patients were divided into two groups. The control group (68 patients) included patients without sarcopenia. The main group consisted of 41 patients who were diagnosed with sarcopenia. Results. Among patients in the compared groups, there were no statistically signifi cant diff erences in age, sex, ASA score and body mass index. Th ere was no statistically signifi cant diff erence in the incidence of major complications (Clavien-Dindo III / IV) (p = 0.2), however, the incidence of postoperative infectious complications was signifi cantly higher in patients from the study group compared to the control group (63.4 % versus 39.7 %, respectively, p = 0.01), as well as the incidence of postoperative clinically signifi cant pancreatic fi stulas (36.6 % versus 17.6 %, respectively, p = 0.02), as well as mortality (9.8 % versus 1.5 %, respectively, p = 0.04).

Online review platforms present them with multiple cues by which to assess whether a review message is useful in their decision-making process. However, consumers are often faced with conflicting opinions from different information sources. By using the theoretical framework of dual-process theory and signaling theory, this paper examines the effect of majority and minority influences.It further investigates how expert reviewers are perceived, and the role played by the total number of available reviews. A 2 x 2 x 2 (review valence x expertise of conflicting review x number of reviews) scenario-based experiment is conducted. The results demonstrate that expert sources weaken the prominent influence of the majority, especially when majority size is small. The research contributes to existing literature by explaining how the simultaneous presence of majority and minority influences affects consumers’ decision-making process. Moreover, it examines the power of online expert reviewers.","PeriodicalId":17054,"journal":{"name":"Journal of Software Maintenance and Evolution: Research and Practice","volume":"25 1","pages":"119-129"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86013578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central indicator value of intersegmental compression-distractive kinetics and loads shift s related to these factors was also determined. When considering the objectivity of spine biomechanics video analysis, the reliability of kinetics and spinal motion segments kinematics was separately assessed. Furthermore, impropriety of the latter was established in terms of reliability and repeatability of diagnostic results. Only vertical force indicator is valid in kinetics, reflecting intersegmental compression load, due to the sufficient objectivity and weak dependence of its values on the type of computer mathematical models used by commercial systems of video motion analysis. Walking is optimal motional act for calculating vertical force by modern optoelectronic soft ware and hardware systems.","PeriodicalId":17054,"journal":{"name":"Journal of Software Maintenance and Evolution: Research and Practice","volume":"1 1","pages":"34-48"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83073505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. Three patients with purulent nonspecifi c spondylodiscitis of lumbar spine got minimally invasive surgical treatment. The essence of surgical intervention included X-ray-assisted placement of tubular retractors in the area of intervertebral disc aff ected by purulent process; debridement and irrigation with antiseptic solution of interbody space, and setting a drain tube. All patients were treated during the period from December 2016 to February 2019. They were examined before surgery and in 3 months aft er the discharge. Laboratory parameters (CBT, C-reactive protein, bacteriological analysis of intervertebral disc contents) and instrumental research methods (computer tomography, magnetic resonance imaging) were evaluated. ODI, VAS, SF-36 questionnaires helped to assess pain syndrome and life quality of patients. Results. In 100 % of studied cases infection was caused by Staphylococcus aureus. The result of treatment in all cases was assessed as good, because pain syndrome, neurological disorders and inflammatory process were arrested; there were no signs of disease progression. In all cases, life quality of patients was restored. In one case, additional surgical intervention was required (posterior instrumental fi xation of spine) because of instability signs. Conclusion. Minimally invasive surgical treatment of purulent single-level spondylodiscites can be recommended for practical use.

Th e aim of this study was to study the polymorphism of the ADRB2 gene, as well as the frequency and nature of cardiovascular complications in its presence in patients with severe pneumonia with infl uenza A/H1N1/09. Material and methods. Th e study included 100 patients with pneumonia with infl uenza A/H1N1 / 09 in 2019 in the Trans-Baikal Territory. All patients were treated in the intensive care unit. In patients, the causative agent-infl uenza virus A/H1N1 / 09 was verifi ed by PCR-detection of the pathogen in nasopharyngeal smears or hemagglutination inhibition test (HIT) with an increase in the antibody titer in paired sera. DNA was isolated from peripheral blood leukocytes; fragments were amplifi ed by polymerase reaction and genotyped by short fragment length polymorphism for Gln27Glu and Arg16Gly ADRB2. Results. The patients were divided into 2 groups: Group I (n=41) – patients with cardiovascular complications; group II (n=59) – patients without cardiovascular complications. Th e groups were comparable in gender and age. Among the cardiovascular complications prevailed: arrhythmias (n=13); decompensation of chronic heart failure (n=13); acute myocardial infarction (n=7); pulmonary embolism (n=5); myocarditis/pericarditis (n=3). When studying the ADRB2 polymorphism, it was found that the most unfavorable variant is the homozygous mutation Arg16Gly (Gly/Gly). This mutation was detected in 6 (14.6 %) patients in group I, but was not detected in group II (P=0.003). In the presence of this mutation in patients with severe secondary viral-bacterial pneumonia with infl uenza A/H1N1 / 09, the risk of developing cardiovascular complications increases (HR=2.6; CI 2.06; 3.49). Conclusion. Patients with severe pneumonia during the A/H1N1/09 infl uenza epidemic in 2019 had a high incidence of cardiovascular complications (41 %).
