- This study examines the applicability of an extended technology acceptance model (TAM) that incorporates trust, perceived risk, and self-enhancement as antecedents to the TAM constructs. Data collected from 299 Vietnamese online consumers, through a self-administered survey, were entered into a structural equation model using AMOS 23 to establish causality. The results partially confirm the applicability of TAM to the online shopping intentions of Vietnamese consumers, though contrary to expectations, perceived ease of use does not predict behavioral intentions. Trust and self-enchantment fit well with the TAM; the inclusion of perceived risk as an antecedent is questionable. The findings offer new opportunities for explaining TAM theory in light of Schwartz’s value dimensions. This article thus concludes with a discussion of the research contributions and implications.

- Purpose – This study examines the drivers of country-level high Social Media Penetration (SMP) rate by considering the concurrent causation of cultural and socio-economic conditions.Method – Ninety-four countries across continents were analyzed using the set-theoretic configurational approach fuzzy set Qualitative Comparative Analysis (fsQCA 3.0).Findings – Results reveal that the adult literacy rate is the necessary condition and found four causal combinations for high SMP.Limitations – Limitations related to using secondary data at a single point and including only two socio-economic conditions in the design are recognized.Contributions to literature- This study is believed to be among the first to use QCA for testing and providing evidence of SMP as an outcome of cultural and social-economic conditions. It contributes to theory by advancing our knowledge of what combination of cultural and social-economic factors would result in high or low SMP.Practical Implications- This study provides managerial implications for both digital marketers and social media technology designers and suppliers. With the increasing connectedness in this digital age, global marketers should be more mindful and respectful of the expectations of their customers around the world and shape their decision-making processes accordingly. Social media can be a very effective tool to help global marketers learn about other cultures, overcome adjustment challenges, and establish as well as maintain relationships. All these can accelerate the integration into the host culture during their adaptation (Sawyer and Chen, 2012). Our study provides greater insights of what combination of cultural and social-economic conditions may facilitate or inhibit the adoption of their platforms. Our findings can also help social media managers in their global targeting initiatives. Customized social media programs can be designed to target a specific cluster of countries according to usage patterns based on technological capability and social norms.Social implications- More and more reports have been published to attest to the economic and social impact of social media. Despite the rapid growing influence on our societies, social media remains a relatively untapped source of information to catalyze policy action and social change (Yeung, 2018). Our study offers insight for social policy making by identifying multiple paths to enhance social media’s penetration as decision makers increasingly realize its potential and long-term benefits resulted from continued use of social media analytics.Originality- This study is believed to be among the first to use QCA for testing and providing evidence of SMP as an outcome of cultural and social-economic conditions. It identifies four complex antecedent paths that are responsible for high SMP, allowing for a more comprehensive explanation of our outcome of interest.

- This research integrates transaction cost and relational exchange theories to depict a more nuanced explanation of exporter-importer exchange relationships when exporters operate from a developing country. Our study examines whether exporters’ investments in specific assets directly influence perceived importer opportunism, or whether these perceptions are driven by the mediating effects of interpersonal and inter-organizational trust and power. Contrary to the general transaction cost argument, we did not find any direct effect of exporter specific assets on perceived importer opportunism. Instead, we found that perceived importer power and exporter inter-organizational trust jointly mediate the exporter specific assets – perceived importer opportunism relationship. By incorporating a dimensional view of trust, we help to resolve conflicting theoretical specifications and empirical results found in the extant literature.

Tidskriftsartikel (refereegranskat)abstract
- Background: Educational environments are considered important in strengthening students’ health status and knowledge, which are associated with good educational outcomes. It has been suggested to establish healthy universities based on a salutogenic approach – namely, health promotion. The aim of this study was to describe health-promoting resources and factors among first-semester students in higher education in healthcare and social work.Methods: This cross-sectional study is based on a survey distributed among all students in seven healthcare and social work programmes at six universities in southern Sweden. The survey was carried out in 2018 using a self-reported, web-based questionnaire focussing on general health and well-being, lifestyle factors together with three validated instruments measuring health-promoting factors and processes: the Sense of Coherence (SOC) scale, Salutogenic Health Indicator Scale (SHIS) and Occupational Balance Questionnaire (OBQ).Results: Of 2283 students, 851 (37.3%) completed the survey, of whom 742 (87.1%) were women; 722 (84.8%) were enrolled on healthcare programmes, and 129 (15.2%) were enrolled on social work programmes. Most reported good general health and well-being (88.1% and 83.7%, respectively). The total mean scores for the SOC scale, SHIS and OBQ were, respectively, 59.09 (SD = 11.78), 44.04 (SD = 9.38) and 26.40 (SD = 7.07). Well-being and several healthy lifestyles were related to better general health and higher SOC, SHIS and OBQ scores. Multiple linear and logistic regressions showed that perceived well-being and no sleeping problems significantly predicted higher general health and higher SOC, SHIS and OBQ scores. Being less sedentary and non-smoking habits were significant predictors of higher SOC.Conclusions: Swedish students in higher education within the healthcare and social work sector report good general health and well-being in the first semester, as well as health-promoting resources (i.e. SOC, SHIS and OBQ), and in some aspects, a healthy lifestyle. High-intensity exercise, no sleeping problems and non-smoking seem to be of importance to both general health and health-promotive resources. This study contributes to knowledge about the health promotive characteristics of students in the healthcare and social work fields, which is of importance for planning universities with a salutogenic approach.

- Citation is how we acknowledge our debt to those who came before; those who helped us find our way when the way was obscured because we deviated from the paths we were told to follow. Sara Ahmed reminds us that just citational practices recognize the knowledge contributions of less dominant, routinely overlooked voices. Pursuing citational justice, then, entails moving away from individualistic views of authorship and toward a shared, reciprocal understanding of how knowledge is produced. Drawing from our experiences working within HCI, we extend an invitation for a just citational practice—one that makes space for the diversity of human experience and recognizes that human-computer interactions must be responsive to cultural and geographic differences. We outline parts of our ongoing conversations as a collective to motivate a careful citation practice across our field, interrogating how we can best honor one another’s ideas and labor without alienation or appropriation.

Tidskriftsartikel (refereegranskat)abstract
- Background: Midline laparotomy is the definitive treatment for sigmoid volvulus after initial colonoscopic detorsion. We successfully adopted another technique at our center on 6 patients, treating sigmoid volvulus by left iliac fossa mini-incision. Presentation of cases: We report our experience of six non-consecutive cases of sigmoid volvulus treated by left iliac fossa mini-incision. The cases were a 33 year old Egyptian female, a 21 year old Bangladeshi male, a 58 year old Qatari male, a 30 year old Ethiopian male, a 36 year old Ugandan male, and a 58 year old Indian male. The six cases are unique in the surgical technique employed in their management. This is possibly the second case series of left iliac fossa mini-incision for sigmoid volvulus in the Middle East and North Africa Region. Discussion: All patients underwent initial colonoscopic detorsion followed by sigmoidectomy and anastomosis. The procedure was successful in treating the volvulus in five patients with no complication or recurrence over a mean follow up of 8 months (range: 1–36 months). One patient required further laparotomy and resection with anastomosis due to incompletely removed sigmoid colon. Conclusions: Left iliac fossa mini-incision for sigmoid volvulus is safe, feasible, cosmetically appealing and with low morbidity.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor that originates from the parafollicular C cells of the thyroid gland. MTC can be due to sporadic or hereditary causes due to gain of function germ line mutations in the RET proto-oncogene. MTC presenting as ocular symptoms due to choroidal mass is rare with bad prognosis. Presentation of case: A 38-year-old Sudanese male presented to Hamad General Hospital, complaining of sudden painless decrease of vision of the right eye of 3 weeks duration. After investigations using imaging methods, the patient was discovered to have metastatic MTC that presented as choroidal mass and metastasized to his lung, bone, brain, pituitary, liver and mediastinum. Discussion: In terms of investigations, serum levels of calcitonin have superior diagnostic accuracy. Our patient undertook diagnostic imaging including ultrasonography, fine needle aspiration and computerized tomography (CT) scan and/or MRI imaging. He undertook total thyroidectomy and left neck dissection followed by stereotactic radiosurgery for the right orbit and pituitary. He then received systemic anti-RET therapy (Selpercatinib). At 5 months follow up there was dramatic drop in CEA from 888 μg/L to 164 μg/L, and calcitonin from >585.2 pmol/L to 354 pmol/L. Conclusion: Choroidal metastasis as initial presentation of MTC is extremely rare and challenging to diagnose. Surgeons need a high index of suspicion when ocular symptoms accompany a neck mass or thyroid-related symptoms. MTC has a progressive course with involvement of blood vessels and neck lymph nodes. Choroidal metastasis of MTC is challenging to manage.

- Introduction: Non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP) is a recently characterized lesion with very low malignant potential. This has allowed for less aggressive management of this tumor subtype. Papillary thyroid carcinoma (PTC) has malignant potential and requires different considerations in management. Presentation of case: A 33-year-old woman presented to our Thyroid Surgery Clinic with a left neck swelling slowly enlarging over 4 years, and recent right-sided neck pain. Neck ultrasound and fine needle aspiration for cytology found bilateral thyroid nodules, labelled as ‘follicular lesion of undetermined significance’ (FLUS). Final pathology report after total thyroidectomy identified four distinct tumors: bilateral NIFTP lesions and bilateral papillary microcarcinomas. Discussion: Management of NIFTP comprises partial or total thyroidectomy without further intervention. Management of PTC is the same but with the possible addition of radioactive ablation due to the increased malignant potential. This is the first report of bilateral NIFTP lesions and bilateral papillary microcarcinomas co-occurring together in the same patient, so management was challenging. The decision was made to give the patient low dose radioactive iodine ablation and continue monitoring. Ultrasound of the neck follow up 6 months later showed no residual thyroid tissue or local recurrence. Conclusion: Although rare, NIFTP can co-occur with PTC. Bilateral NIFTP with bilateral PTC is extremely rare. Surgeons and pathologists need to be aware of this rare entity that can co-occur in both thyroid lobes. Total thyroidectomy is the definitive treatment. Post-surgery surveillance is important and follow up needs to be watchful for any recurrence or metastasis. © 2020 The Author(s)

- Introduction: Noninvasive follicular thyroid neoplasm with papillary-like nuclear (NIFTP) is a new entity. No previous study reported prospective cases, outlining using many quantitative and qualitative variables. Methods: Retrospective analysis of all (15) prospective NIFTP cases diagnosed between 2017 and 2021 at our institution. Statistical quantitative analysis outlined demographic, history, ultrasound, histopathology and treatment characteristics. Qualitative analysis examined the cases, with details provided on three cases to highlight the different possible presentations and configurations. Results: Mean age was 41.5 ± 9.91 years, 73.3% were females, and mean BMI was 29.49 ± 5.74 kg/m2. About 87% patients were symptomatic; 86.6% had neck swelling. Ultrasound (US) showed multiple nodules in 71.4% of cases. Fine-needle aspiration cytology (FNAC) showed that follicular lesion of undetermined significance (42.8%) was most common, followed by benign nodule (21.3%). Using the Bethesda System for Reporting Thyroid Cytopathology, 7 cases were category III, 3 category IV, 3 category II, and 1 category I. 60% of patients underwent total thyroidectomy. All cases were diagnosed postoperatively, 2 patients had additional papillary microcarcinoma. In 3 cases, the NIFTP site in the histopathology of resected specimen was different than the US-recommended site of the FNAC. Conclusion: We found discrepancies in the site and diagnosis of the preoperative US recommendation for the FNAC vs the postoperative histopathology of the specimen. These suggest that NIFTP might be incidentally and postoperatively diagnosed, irrespective of US or FNAC findings, hence its ‘true’ incidence might remain underestimated. As NIFTP cases higher BMI, Future research could predict preoperative diagnosis of NIFTP and explore associations with BMI.
