Studying the influence of technology on the social connectedness of students : a hybrid university learning environment (HULE)

Student social connectedness is indicated to be changing as universities are becoming more digitalised. Although social connectedness is shown to have a significant influence on the learning process, little is understood about the relationship between student social connectedness and the hybrid university learning environment (HULE). This empirical study aims to develop understandings by exploring student social connectedness in a hybrid-style class at a Swiss university. The study applies theories of placemaking and socio-materiality to explore students’ self-reported and observed perceptions of individual social connectedness at the start of a university master’s level course. The qualitative study is conducted using questionnaire data and observational data collected over the first month of a new course starting in the Autumn semester. The findings indicate that although students favour flexibility to design their learning space, they require the appropriate tools and guidance in which to make effective decisions for their social connectedness. Understanding the correct implementation of co-design for the HULE is therefore deemed important to facilitate social connectedness, this is particularly necessary for the liminal space. These findings are preliminary as part of a larger research project and offer a basis for further research to be developed. This study offers an innovative perspective of the HULE based on student social connectedness, impacting the existing pedagogical approach for university courses

The representation of voluntourism in search engines: The case of South Africa

© 2015, © 2015 Government Technical Advisory Centre (GTAC). This paper responds to the paucity of research on the linkages between voluntourism and digital technology and seeks to understand the online representation of the phenomenon in a developing context. In particular, the researchers investigate the so-called ‘online domain’ of voluntourism in South Africa. The researchers collected a series of web results from search engines and analysed the presence of traditional and social media websites, the most relevant presented topics, and the type of argumentation found. Results identify the context and representation of voluntourism as it transpires virtually. This will contribute to the understanding of the interplay between voluntourism and digital technology, with specific emphasis on web presence. Ultimately, results will shed light on how digitally accessible voluntourism is in South Africa and will set the basis for future investigations

Consumer behaviour in tourism: Concepts, influences and opportunities

Although consumer behaviour (CB) is one of the most researched areas in the field of tourism, few extensive reviews of the body of knowledge in this area exist. This review article examines what we argue are the key concepts, external influences and opportune research contexts in contemporary tourism CB research. Using a narrative review, we examine the CB literature published in three major tourism journals from 2000 to 2012. Of 519 articles identified and reviewed, 191 are included in this article. We examine the development of and scope for future research on nine key concepts, including decision-making, values, motivations, self-concept and personality, expectations, attitudes, perceptions, satisfaction, trust and loyalty. We then examine three important external influences on tourism behaviour, technology, Generation Y and the rise in concern over ethical consumption. Finally, we identify and discuss five research contexts that represent major areas for future scholarship: group and joint decision-making, under-researched segments, cross-cultural issues in emerging markets, emotions and consumer misbehaviour. Our examination of key research gaps is concluded by arguing that the hedonic and affective aspects of CB research in tourism must be brought to bear on the wider CB and marketing literature

Lessons learned from a faulty transoral endoscopic thyroidectomy vestibular approach

Background: Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) is currently considered the most promisingly scarless approach to the thyroid and has gained more acceptance. Materials and Methods: We described a case of faulty TOETVA. Results: The faulty TOETVA resulted in pneumomediastinum, diffuse subcutaneous emphysema, prolonged surgery, and anesthesia. Conclusions: The important technical considerations during TOETVA, including the use of external retraction, the identification of the subplatysmal plane of dissection, CO 2 insufflation settings, the learning curve, and patient selection, were described and discussed

Early intact PTH (iPTH) is an early predictor of postoperative hypocalcemia for a safer and earlier hospital discharge: An analysis on 260 total thyroidectomies

Background: Hypocalcemia is the most frequent complication after thyroidectomy. Serum calcium levels are reliable only 48-72 hours postoperatively. Early intact PTH (iPTH) has been proposed as early predictor of postoperative hypocalcemia. Our aim is to assess the ability of iPTH in predicting postoperative hypocalcemia. Methods: Two hundred and sixty patients underwent thyroidectomy with postoperative iPTH evaluation. The iPTH samplings were early performed after thyroidectomy. The calcium levels were dosed postoperatively. Age, sex, clinical diagnosis, obesity, comorbidities, previous neck surgery, preoperative therapy, type of surgery, dissectors used, lymphadenectomy, post-operative complications, reoperation and histological diagnosis were considered. The primary end-point was the postoperative hospital stay. The secondary end-points were serum calcium and iPTH. Three iPTH cut-offs were tested to assess which was the best value (10.0, 15.0, and 20.0 pg/mL). Results: The iPTH cut-off value of 10.0 pg/mL was the most accurate and specific for hypocalcemia. Comparing the iPTH value with the different values of calcium respectively 24 and 48 hours after surgery, a statistically stronger association with the serum calcium levels 48 hours postoperatively has been shown. iPTH 65 10 pg/mL 3-6 hours after surgery was strongly correlated to early discharge. Conclusions: The correlation of iPTH with hypocalcemia is significant since a few hours after surgery and the value of iPTH 65 10 pg/mL is able to select those patients for a safe and early discharge. The use of the iPTH might avoid unnecessary extensions of hospitalization

Thyroidectomy in elderly patients aged 6570 years

Worldwide, the indications for thyroid surgery have been continuously extended among elderly patients in the last 20 years. The balance between treatment indication and surgical risk is certainly an interesting topic for every thyroid surgeon. This paper is a review of recent literature from January 2005 up to April 2017. We analyzed three principal subjects: indications for surgical treatment, medical complications and surgical complications. We can summarize the conclusions of our analysis, stating that age could not be considered as an absolute factor, but in relation to the comorbidities and the general clinical condition of the patient. Special risk indices dedicated to geriatric patients could be very useful in order to facilitate the decision-making process; however, relying on the current knowledge, we could state that there is value in providing surgery to geriatric patients in highly specialized and high-volume centers, where access to technology and its systematic use, coupled with surgeons' experience, could certainly avail the geriatric patient management

Peri-operative blood transfusion in gastric cancer surgery: prognostic or confounding factor?

Background and Purpose: The relationship between peri-operative blood transfusions (PBTs) and poor prognosis in gastric cancer (GC) patients is still debated. The aim of this study is to examine the real prognostic impact of PBTs in comparison to well-known prognostic factors. Methods: We retrospectively analyzed a series of 224 patients who underwent surgery with curative intent for GC from January 1995 to December 2011. Among 224 patients, 46 (20%) required PBTs. Results: The overall 5-year survival was 77% in non-transfused patients and 65% in patients who received PBTs (p = 0.03). PBTs did not further stratify any recognized prognostic category (such as pT or pN according to the 7th edition of the TNM staging system). Multivariate analysis including all known prognostic variables (both cancer- and non-cancer-related) did not select PBTs as an independent prognostic factor. Only preoperative hemoglobin and albumin level, pT and operative time were significantly associated with the requirement for PBTs. Conclusions: The study showed a worse prognosis for transfused patients, but PBTs seem a confounding factor more than a prognostic indicator, as they are obviously affected by other variables
