Accessibility Challenges of Using Podcasts and Vodcasts in a South African Distance Learning University

Academic writing presents a range of challenges for students, particularly those enrolled in distance university institutions. These challenges encompass various facets such as understanding citation and referencing, developing a distinctive writer’s voice, mastering academic discourse, paraphrasing, summarising, and adhering to academic conventions. Notably, deficiencies in academic writing skills often trace back to inadequate preparation during high school education, potentially leading to qualification deferment and high dropout rates. To tackle these challenges, podcasts and vodcasts emerged as essential tools to bridge academic gaps, catering to diverse learning styles and offering flexibility beyond traditional teaching methods. However, the efficacy of supplemental multimedia tools warrants exploration, considering uncertainties regarding student acceptance. Thus, this study aimed to identify accessibility challenges, to reduce existing barriers and enhance accessibility in open distant institutions. Utilising qualitative research methodologies, including focus group discussions and literature analysis, data collection was conducted. The study drew upon Moore’s theory of transactional distance and Garrison et al.’s community of inquiry framework to create collaborative online interactions and meaningful lecturer-student engagement, culminating in the construction of new knowledge. Findings revealed that students did not encounter accessibility challenges and expressed preference for shorter podcasts and vodcasts. These multimedia formats alleviated boredom, clarified complex concepts, prevented monotony, enhanced attention and comprehension, stimulated interest, facilitated active learning, and accommodated various learning styles. Podcasts and vodcasts reduced transactional distance and created a sense of community. Contrary to prevailing literature, students did not encounter accessibility challenges, shifting the focus towards shorter, high-quality multimedia content rather than accessibility concerns.

A Privacy-Preserving Distributed Medical Data Integration Security System for Accuracy Assessment of Cancer Screening: Development Study of Novel Data Integration System

Big data useful for epidemiological research can be obtained by integrating data corresponding to individuals between databases managed by different institutions. Privacy information must be protected while performing efficient, high-level data matching. Privacy-preserving distributed data integration (PDDI) enables data matching between multiple databases without moving privacy information; however, its actual implementation requires matching security, accuracy, and performance. Moreover, identifying the optimal data item in the absence of a unique matching key is necessary. We aimed to conduct a basic matching experiment using a model to assess the accuracy of cancer screening. To experiment with actual data, we created a data set mimicking the cancer screening and registration data in Japan and conducted a matching experiment using a PDDI system between geographically distant institutions. Errors similar to those found empirically in data sets recorded in Japanese were artificially introduced into the data set. The matching-key error rate of the data common to both data sets was set sufficiently higher than expected in the actual database: 85.0% and 59.0% for the data simulating colorectal and breast cancers, respectively. Various combinations of name, gender, date of birth, and address were used for the matching key. To evaluate the matching accuracy, the matching sensitivity and specificity were calculated based on the number of cancer-screening data points, and the effect of matching accuracy on the sensitivity and specificity of cancer screening was estimated based on the obtained values. To evaluate the performance, we measured central processing unit use, memory use, and network traffic. For combinations with a specificity ≥99% and high sensitivity, the date of birth and first name were used in the data simulating colorectal cancer, and the matching sensitivity and specificity were 55.00% and 99.85%, respectively. In the data simulating breast cancer, the date of birth and family name were used, and the matching sensitivity and specificity were 88.71% and 99.98%, respectively. Assuming the sensitivity and specificity of cancer screening at 90%, the apparent values decreased to 74.90% and 89.93%, respectively. A trial calculation was performed using a combination with the same data set and 100% specificity. When the matching sensitivity was 82.26%, the apparent screening sensitivity was maintained at 90%, and the screening specificity decreased to 89.89%. For 214 data points, the execution time was 82 minutes and 26 seconds without parallelization and 11 minutes and 38 seconds with parallelization; 19.33% of the calculation time was for the data-holding institutions. Memory use was 3.4 GB for the PDDI server and 2.7 GB for the data-holding institutions. We demonstrated the rudimentary feasibility of introducing a PDDI system for cancer-screening accuracy assessment. We plan to conduct matching experiments based on actual data and compare them with the existing methods.

Ecosystem-based management of coral reefs from afar – A guide for remote scientists and remote places

Modern-day coral reef conservation requires connections between researchers, decision-makers and stakeholders to achieve holistic ecosystem-based management (EBM), rooted in and supported by local communities. However, the COVID-19 pandemic, global political and financial instability and growing concerns over emissions from air travel have meant that face-to-face meetings and in-person fieldwork are increasingly difficult for many researchers at distant institutions. In this paper we discuss how to achieve EBM remotely, using a combination of freely available online data, remote fieldwork techniques and virtual communication and engagement tools. We highlight resources that have been useful in our work for components of overseas EBM and discuss lessons learned from those experiences.There are benefits to remote working, including reduced carbon emissions and travel costs, the ability to record and re-use electronic training materials, the ability to reach a wider audience than through face-to-face meetings and an increased reliance and division of labour with local researchers and stakeholders. However, developing new relationships and gaining a deeper contextual understanding of the local site and culture is not easily replaced by online or remote methods. Post-COVID-19, it is likely that some aspects of remote working within coral reef conservation will continue, as in many other aspects of global collaboration. We propose a blended approach where much of the work and collaboration is conducted online, but with some in-person visits to develop the key relationships or decisions are needed.

Predictors of Chronic Combat-Related Post-Traumatic Stress Disorder Group Psychotherapy Favorable Outcomes; A Prospective Cohort Study in Croatia.

Combat-related chronic post-traumatic stress disorder (PTSD) is a therapeutically resistant disorder of the fluctuating course. The success of a group psychotherapy is partial. The aim of this paper is to determine baseline characteristics of veterans for whom a group psychotherapy will be the effective psychotherapeutic treatment. We performed this prospective cohort study in two geographically distant institutions: Regional Psychotrauma Center at the Psychiatric Clinic Split, and the Daily Hospital of the Psychiatric Hospital "Sveti Ivan" Zagreb, Croatia. We selected a consecutive sample of 86 veterans with combat-related chronic PTSD admitted to the group psychotherapy during 2009-2012. The primary outcome was ≥5% improvement in PTSD symptoms severity measured by Mississippi Scale for Combat-Related PTSD and adjusted for the baseline Mississippi scale score. Predictors were participants' 17 baseline sociodemographic and clinical characteristics and psychological features like personality traits, stress-coping mechanisms, and depression. We identified two patients' segments with significantly higher likelihood for the favorable treatment outcome. The first one were patients with the low score (≤8) on the phobia scale and high score (≥7) on the hysterical personality scale. In this segment 100% of patients experienced a favorable treatment outcome. The second one were the patiens with a higher score (>8) on the phobia scale, the low score (≤12) on the free-floating anxiety scale and the high score ≥8) on the obsession scale. In this segment, 64% experienced the favorable treatment outcome. The favorable outcome of the group psychotherapy of PTSD symptoms severity in patients with combat-related chronic PTSD can be predicted before the start of the treatment. The favorable outcome should be expected in patients with the low phobia and pronounced hysteria personality traits, or in patients with higher phobia, but with low free-floating anxiety and low obsession.

Headache Education Adaptation During the COVID-19 Pandemic: Impact on Undergraduate and Graduate Medical Education.

Purpose of ReviewOur goal was to describe the changes to headache and neurological education that occurred as a result of the COVID-19 pandemic, and the impact this had on medical learners. We also discuss subsequent implications for the future of education in the field of headache medicine.Recent FindingsBoth educators and learners faced many challenges during the pandemic. These include the following: cancellation of in-person educational meetings, limited in-person networking and wellness events, disengagement from virtual didactic curricula, limitations in procedure-based learning, redeployment to inpatient settings with a decrease in outpatient exposures, and blurred boundaries between home and work life due to more virtual collaboration and home computer use. The development of telehealth programs and trainee wellness initiatives, improved collaboration opportunities among geographically distant institutions, and greater access to conferences for learners are among the many improvements forged by these challenging times in medical education.SummaryGiven the high prevalence of headache disorders and the paucity of headache specialists, training new clinicians with competency in headache medicine is essential. There were many educational challenges and opportunities identified in the literature that resulted from the pressures of the pandemic. Educators need to develop assessments that capture any gaps in learning that may have occurred during this tumultuous time and be vigilant of remediation needs in our learners over the coming years. It is imperative to intentionally design curricula for the future by harnessing new pedagogical tools, innovations, and perspectives gleaned from our experience with the COVID-19 pandemic.

Identification of early invisible acute ischemic stroke in non-contrast computed tomography using two-stage deep-learning model.

Rationale: Although non-contrast computed tomography (NCCT) is the recommended examination for the suspected acute ischemic stroke (AIS), it cannot detect significant changes in the early infarction. We aimed to develop a deep-learning model to identify early invisible AIS in NCCT and evaluate its diagnostic performance and capacity for assisting radiologists in decision making.Methods: In this multi-center, multi-manufacturer retrospective study, 1136 patients with suspected AIS but invisible lesions in NCCT were collected from two geographically distant institutions between May 2012 to May 2021. The AIS lesions were confirmed based on the follow-up diffusion-weighted imaging and clinical diagnosis. The deep-learning model was comprised of two deep convolutional neural networks to locate and classify. The performance of the model and radiologists was evaluated by the area under the receiver operator characteristic curve (AUC), sensitivity, specificity, and accuracy values with 95% confidence intervals. Delong's test was used to compare the AUC values, and a chi-squared test was used to evaluate the rate differences.Results: 986 patients (728 AIS, median age, 55 years, interquartile range [IQR]: 47-65 years; 664 males) were assigned to the training and internal validation cohorts. 150 patients (74 AIS, median age, 63 years, IQR: 53-75 years; 100 males) were included as an external validation cohort. The AUCs of the model were 83.61% (sensitivity, 68.99%; specificity, 98.22%; and accuracy, 89.87%) and 76.32% (sensitivity, 62.99%; specificity, 89.65%; and accuracy, 88.61%) for the internal and external validation cohorts based on the slices. The AUC of the model was much higher than that of two experienced radiologists (65.52% and 59.48% in the internal validation cohort; 64.01% and 64.39% in external validation cohort; all P < 0.001). The accuracy of two radiologists increased from 62.00% and 58.67% to 92.00% and 84.67% when assisted by the model for patients in the external validation cohort.Conclusions: This deep-learning model represents a breakthrough in solving the challenge that early invisible AIS lesions cannot be detected by NCCT. The model we developed in this study can screen early AIS and save more time. The radiologists assisted with the model can provide more effective guidance in making patients' treatment plan in clinic.

ECMO therapy in COVID-19: An experience from Zurich.

The current coronavirus disease 2019 (COVID-19) pandemic has a huge impact on society and the economy and represents one of the biggest challenges for healthcare systems all over the world. Reports from healthcare institutions in different countries show a variety of crisis exit strategies. The following is a review and update of the situation and crisis management in Zürich and Switzerland with a special focus on the impact on the cardiac surgery program and extracorporeal membrane oxygenation (ECMO)-therapy in COVID-19. Regional and national measures had avoided thecollapse of the health system in Switzerland. There was a reduction of over 50% of the surgical and transcatheter caseload during the first wave of the pandemic. Twenty-three ECMO devices, 150 oxygenators, and more than 300 different cannulas were atour disposal. Between March and May 2020, nine COVID-19 patients were treated by us with ECMO-therapy. Three patients were transported by us from distant institutions. Median age at ECMO implantation was 59 years. Two patients died on support. Measures to prevent a collapse of the healthcare system were effective. Our local ECMO-Program on the ongoing COVID-19 pandemic has proven to be a useful tool to control mortality and organ failure in critically ill patients.

A quantitative imaging biomarker for predicting disease-free-survival-associated histologic subgroups in lung adenocarcinoma.

Classification of histologic subgroups has significant prognostic value for lung adenocarcinoma patients who undergo surgical resection. However, clinical histopathology assessment is generally performed on only a small portion of the overall tumor from biopsy or surgery. Our objective is to identify a noninvasive quantitative imaging biomarker (QIB) for the classification of histologic subgroups in lung adenocarcinoma patients. We retrospectively collected and reviewed 1313 CT scans of patients with resected lung adenocarcinomas from two geographically distant institutions who were seen between January 2014 and October 2017. Three study cohorts, the training, internal validation, and external validation cohorts, were created, within which lung adenocarcinomas were divided into two disease-free-survival (DFS)-associated histologic subgroups, the mid/poor and good DFS groups. A comprehensive machine learning- and deep learning-based analytical system was adopted to identify reproducible QIBs and help to understand QIBs' significance. Intensity-Skewness, a QIB quantifying tumor density distribution, was identified as the optimal biomarker for predicting histologic subgroups. Intensity-Skewness achieved high AUCs (95% CI) of 0.849(0.813,0.881), 0.820(0.781,0.856) and 0.863(0.827,0.895) on the training, internal validation, and external validation cohorts, respectively. A criterion of Intensity-Skewness ≤ 1.5, which indicated high tumor density, showed high specificity of 96% (sensitivity 46%) and 99% (sensitivity 53%) on predicting the mid/poor DFS group in the training and external validation cohorts, respectively. A QIB derived from routinely acquired CT was able to predict lung adenocarcinoma histologic subgroups, providing a noninvasive method that could potentially benefit personalized treatment decision-making for lung cancer patients. • A noninvasive imaging biomarker, Intensity-Skewness, which described the distortion of pixel-intensity distribution within lesions on CT images, was identified as a biomarker to predict disease-free-survival-associated histologic subgroups in lung adenocarcinoma. • An Intensity-Skewness of ≤ 1.5 has high specificity in predicting the mid/poor disease-free survival histologic patient group in both the training cohort and the external validation cohort. • The Intensity-Skewness is a feature that can be automatically computed with high reproducibility and robustness.

A Bloody Tale of Two Cities: A Study of an Online Hematopathology Course among Students in Toronto and Nairobi

Introduction: To provide comprehensive hematopathology teaching, a web-based virtual microscopy unknown case conference series was created, shared and evaluated for pathology trainees at two geographically distant institutions. This study aimed to determine if web-based simulation of pathology unknown case conferences enhanced the learning of hematopathology trainees based on their own perceptions. Methods: An 8-week web-based unknown case conference series was created and linked to virtual microscopy images. A survey was distributed to participants and focus group interviews were conducted at each institution and qualitative analysis of the responses was undertaken. Results: Residents from hematological, anatomic and clinical pathology residency training programs at a Canadian university and a Kenyan university teaching hospital participated in the study. All active participants experienced an enhancement of their learning. They found virtual microscopy to be a convenient method to learn hematopathology. The design of the unknown case conference series was felt to help them keep focused on the content. Discussion: The online unknown case study approach using virtual microscopy enhanced learning for the residents and in the case of the Kenyan group, provided a learning opportunity not previously present. Residents found the virtual microscopy approach to be convenient and acceptable. Residents were reluctant to participate in the online conference unless they could be sure that their responses were correct, which limited beneficial discourse.

The Geography of Institutional Investors, Information Production, and Initial Public Offerings

We analyze how the geographical locations of institutions affect their investments in IPOs and various characteristics of the IPOs that they invest in. We argue that institutions geographically close to each other may influence each other’s investment decisions in IPOs. Further, they may also free-ride on each other's information when evaluating IPOs, resulting in IPOs dominated by geographically clustered institutions reflecting less accurate information signals compared to those dominated by geographically dispersed institutions. We test the implications of the above hypotheses using a measure of institutions' geographical dispersion. Our results can be summarized as follows. First, the equity holdings of institutions in IPOs are influenced more by the investments made by neighboring institutions than by those of distant institutions. An increase in the geographical dispersion of the institutions investing in an IPO is associated with higher IPO price revisions; higher IPO and immediate secondary market firm valuations; larger IPO initial returns; and greater long-run post-IPO stock returns. Further, consistent with an information channel driving the above results, we find that the extent of information asymmetry facing an IPO firm is decreasing in the geographical dispersion of institutions investing in its IPO. Finally, the predictive power of institutional trading post-IPO for subsequent long-run stock returns and earnings surprises for the first fiscal-year end after the IPO is greater for geographically isolated institutions compared to those that are geographically clustered.

Market Definition in Banking: Recent Evidence

Antitrust analysis of bank mergers defines banking markets to be geographically local and to consist of the cluster of financial products supplied by commercial banks. This definition is based on assumptions about households' and small businesses' behavior in purchasing banking services. This article utilizes data from the Survey of Consumer Finances to examine how households' use of financial services and institutions changed between 1989 and 1998. We investigate the extent to which households still focus their purchases of financial services at local depository institutions, as opposed to non-depository or distant institutions, and examine the extent to which purchases are clustered at a single institution. Overall, the results indicate that households continue, to a substantial degree, to obtain certain key asset services, notably checking accounts, at local depository institutions.

HPV-type distribution and reproducibility of histological diagnosis in cervical neoplasia in Poland.

This study was performed to assess attribution of high grade cervical intraepithelial neoplasia (HG-CIN) and invasive cervical cancer (ICC) to human papillomavirus (HPV) genotypes and secondarily to assess reproducibility of HG-CIN/ICC diagnosis obtained in Poland. Formaldehyde fixed, paraffin embedded blocks of HG-CIN/ICC from two distant institutions were sent to a central laboratory together with original histological diagnoses. Central/expert review of histopathological specimens was performed and agreement between local and central/expert diagnoses was calculated. HPV detection and genotyping in the samples was carried out with the use of SPF10-LiPA25 technology. Results were analyzed for 205 HG-CIN and 193 ICC cases with centrally confirmed diagnoses. Kappa coefficients and 95 % confidence intervals for HG-CIN and ICC diagnoses were: 0.13 (0.09;0.17) and 0.19 (0.11;0.26) respectively. Cohen’s kappa coefficients for lesions with representative number of samples ranged from 0.01 for cervical intraepithelial neoplasia grade 2 to 0.75 for adenocarcinoma. HPV DNA was detected in 96.1 and 91.2 % of the confirmed HG-CIN and ICC specimens respectively. HPV positive HG-CIN was most commonly attributed to HPV types: 16 (62.8), 33 (7.8), 31 (6.6), 52 (3.7), 45 (2.6) and 58 (2.6 %). HPV positive ICC was most commonly attributed to HPV types: 16 (72.1), 18 (10.8), 33 (5.7), 45 (3.4) and 31 (1.7 %). Reproducibility of histological diagnosis of HG-CIN/ICC obtained in Poland generally increases with the severity of lesion and is lowest for cervical intraepithelial neoplasia grade 2 and highest for adenocarcinoma. Over 80 % of ICC cases are vaccine-preventable in Poland.

Use of a Data Management System to Provide Glycemic Control Instructions to Diabetic Patients Based on Patient Self-Measured Blood Glucose

To make the treatment for diabetes more effective, we assessed the effects of a data management system for glycemic control. This system enables physicians at distant medical institutions to obtain the fluctuations in blood glucose (BG) measured daily by patients themselves at home and then to give instruction for treatment based on the BG. Use of the system for 2 months resulted in decreases in the hemoglobin A1c (HbA1c) level (from 6.8% ± 0.9% to 6.6% ± 0.8% [ M ± SD], p &lt; .05) and the incidences of preprandial hypoglycemia and postprandial hyperglycemia. These effects can be concluded to have resulted from the fact that physicians become able to give patients appropriate instructions quickly. Also, these effects are considered to have resulted from patient awareness of the importance of self-management of BG.

Template-guided implantation of the Bonebridge: clinical experience.

The surgical procedure for Bonebridge implantation cannot be done in some cases without exposing the dura mater or sigmoid sinus. Surgical simulation technology can help to identify such difficulties prior to surgery and be used to clarify the optimal location and orientation of the device to be implanted. However, there has not been a simple strategy to drill the temporal bone at exactly the same location as that simulated on the computer. Based on our previous development of the surface template-assisted marker positioning (STAMP) method for performing image-guided otologic surgery, we recently developed a noninvasive guiding method, the BB-STAMP method, for performing image-guided Bonebridge implantation. Three patients underwent Bonebridge implantation at our surgical center during the years of 2013-2014. The authors in the simulation center supported the surgery using the BB-STAMP method. The time and effort required to prepare for the surgery were evaluated. In addition, a postoperative analysis was performed to assess the accuracy of placing the device in the planned location. The BB-STAMP method enabled the surgeon to precisely replicate the computer simulation in the real patient with submillimetric accuracy without complexity. Thus, the use of experienced and elaborative simulation coupled with the creation of a tailor-made three-dimensional template (BB-STAMP) enables surgeons to perform quick, precise and safe surgical procedures at distant institutions.

Collaboration through Flickr &amp;amp; Skype: Can Web 2.0 Technology Substitute the Traditional Design Studio in Higher Design Education?

Technology has not only changed the work practice of designers but also how design is taught and learned. The emergence of digital technology has made computer labs a central learning space for design students. Since this change, studio-based learning in its traditional sense appears to be in decline in higher education institutions. This is in spite of the fact that characteristics of the studio have been identified as supporting interaction, active learning, and social engagement. These, however, are also characteristics connected to the use of Web 2.0 technologies such as Facebook, Flickr, and Skype. Could these services be utilized to revitalize studio culture in a contemporary sense? How can new technologies be used to facilitate interactions between students inherent to traditional studio culture? These questions were explored in practice by documenting student reactions to using Flickr and Skype during a five week project requiring collaboration between first year creative arts students at two geographically distant institutions in Australia. Findings provide a better understanding of how to expand the studio idea into the digital environment, in particular regarding the challenging task of offering the media design major fully online in the near future.

58 OVARIAN DOWN-REGULATION WITH ORAL PROGESTIN FOR FIXED-TIME LAPAROSCOPIC OVIDUCTAL ARTIFICIAL INSEMINATION WITH FRESHLY COLLECTED AND FROZEN–THAWED SPERMATOZOA IN DOMESTIC CATS

Laparoscopic oviductal AI (LO-AI) with low numbers of freshly collected or frozen-thawed spermatozoa has resulted in high pregnancy success (50–70%) in domestic cats. However, proper timing of AI depends on identifying anestrual, non-luteal queens before exogenous gonadotropin injection, confounding AI scheduling and limiting applicability with felids housed at distant institutions. Recent research (Stewart et al. 2012 Biol. Reprod. 87, 1–11) has shown that daily oral progestin treatment is effective for down-regulating ovarian activity in cats and allowing synchronized stimulation with exogenous gonadotropins. Our study objectives were to (1) assess the effect of oral progestin treatment on pregnancy success following LO-AI in domestic cats and (2) compare relative fertility following LO-AI of each female with low numbers of freshly collected versus frozen-thawed spermatozoa. Young (&lt;2 years old), nulliparous domestic cats were assigned to either control (Con; n = 8) or oral progestin (OP; n = 7) treatment groups. Con females were monitored daily for behavioural oestrus and blood samples from anestrual females assessed for progesterone concentration to confirm non-luteal status before exogenous gonadotropin treatment [100 IU of eCG followed 85 h later with 1000 IU of porcine LH (pLH)]. Oral progestin females were fed altrenogest (Regu-Mate; 0.088 mg kg–1 of body weight) mixed in moist cat food for 38 consecutive days and then treated with exogenous gonadotropins 6 days after altrenogest cessation. At 31 to 33 h post-pLH treatment, each female was inseminated via laparoscopy in 1 oviduct with freshly collected sperm (motile) from 1 male and frozen-thawed sperm (motile; frozen in a soy lecithin-based cryomedium) from a second male. Ultrasonography was conducted approximately Day 21 post-AI for pregnancy diagnosis. Pregnant females were spayed immediately and recovered fetuses assessed for paternity using short tandem repeat molecular marker analysis to determine relative fertility of fresh versus frozen semen. All females ovulated following gonadotropin treatment, averaging ( ± standard error of the mean) 20.6 ± 1.7 corpora lutea per queen. Most [12/15 (80%)] females conceived following LO-AI, producing an average of 8.1 ± 1.4 implantations and 5.9 ± 1.2 fetuses per pregnancy. There was no difference (P &gt; 0.05) between Con and OP cats in pregnancy success [Con: 6/8 (75%); OP: 6/7 (86%)] or in mean implantation number (Con: 6.0 ± 1.8; OP: 10.2 ± 2.0) or fetal number (Con: 4.3 ± 1.6; OP: 7.5 ± 1.6) in pregnant cats. Paternity assessment revealed that freshly collected and frozen-thawed spermatozoa were equally effective (P &gt; 0.05) in producing pregnancies (fresh: 11/15 (73%); frozen: 10/15 (67%)], with no difference (P &gt; 0.05) in total fetal numbers [fresh: 37/69 (54%); frozen: 32/69 (46%)]. These results indicate that oral progestin treatment may be used to down-regulate ovarian function in felids for fixed-time AI without compromising fertility in vivo, and that LO-AI with low numbers of cat sperm frozen in a soy lecithin medium may produce high pregnancy percentages and normal litter sizes.

The severe shortage of skilled maternity care providers in countries with low resources results in a staggering number of maternal and newborn deaths annually. University nursing and nurse-midwifery programs are especially well-equipped to participate in multi-lateral and bi-lateral education collaborations to address this shortage. This paper presents a perspective on how universities in well-resourced settings especially can share their education capacity with globally distant institutions with chronic unmet needs for well-prepared nurse faculty and skilled midwifery professionals. Start-up administrative, operational and initial site visit considerations were described. Best practices for academic programs and accreditation requirements were reviewed, as well as recommendations for selecting students who are likely to be successful participants. Guides to program success are promoted such as cultural humility, mutual respect, courtesy, and close attention to health, safety, and emotional balance. Key words: Global midwifery, education collaboration, ethics, best practices, education system strengthening.

Rotational Transport of Islets: The Best Way for Islets to Get around?

Islet transplantation is a valid treatment option for patients suffering from type 1 diabetes mellitus. To assure optimal islet cell quality, specialized islet isolation facilities have been developed. Utilization of such facilities necessitates transportation of islet cells to distant institutions for transplantation. Despite its importance, a clinically feasible solution for the transport of islets has still not been established. We here compare the functionality of isolated islets from C57BL/6 mice directly after the isolation procedure as well as after two simulated transport conditions, static versus rotation. Islet cell quality was assessed using real-time live confocal microscopy. In vivo islet function after syngeneic transplantation was determined by weight and blood sugar measurements as well as by intraperitoneal glucose tolerance tests. Vascularization of islets was documented by fluorescence microscopy and immunohistochemistry. All viability parameters documented comparable cell viability in the rotary group and the group transplanted immediately after isolation. Functional parameters assessed in vivo displayed no significant difference between these two groups. Moreover, vascularization of islets was similar in both groups. In conclusion, rotary culture conditions allows the maintenance of highest islet quality for at least 15 h, which is comparable to that of freshly isolated islets.

Transcending the Classroom: A Practical Guide to Remote Role Plays in Teaching International Negotiation

This article discusses the pedagogical value of using remote role plays in cross‐cultural negotiations between two classes taught simultaneously at different and geographically distant institutions. We argue that remote role‐play simulations provide valuable teaching and learning experiences, and are particularly helpful for managing issues associated with outside‐group negotiation and cultural differences, the prenegotiation stage, electronic negotiations and distorted communication, and one‐shot settings in which the negotiator lacks previous knowledge of the partner. The article begins with a discussion of some critical limitations of “traditional” in‐class role plays, followed by a practical guide to remote role plays and a report of our experiences with them. Finally, we discuss the advantages and disadvantages of remote role plays as a teaching tool for international negotiation classes and the key lessons for the participating students.
