Connecting Native Students to STEM Research Using Virtual Archaeology
Authors: Cannon Molly Boeka , Cohen Anna S. , Jimenez Kelly N. 
Published: April 2021

ABSTRACTUniversities struggle to provide meaningful education and mentorship to Native American students, especially in STEM fields such as archaeology and geography. The Native American Summer Mentorship Program (NASMP) at Utah State University is designed to address Native student retention and representation, and it fosters collaboration between mentors and mentees. In spring 2020, as university instruction went online due to the COVID-19 pandemic, NASMP mentors were faced with adapting hands-on activities and face-to-face interaction to an online format. Using our Water Heritage Anthropological Project as a case study, we show how virtual archaeological, archival, spatial, and anthropological labs can be adapted for online delivery. This approach may be especially useful for reaching students in rural settings but also for engaging students in virtual or remote research in the field sciences.
IS TRADING WITH CHINA DIFFERENT? SELF-INTEREST, NATIONAL PRIDE, AND TRADE PREFERENCES
Authors: Yen Wei-Ting , Kay Kristine , Chen Fang-Yu 
Published: April 2021

AbstractDespite increasing economic integrations with China, worries exist in China's neighboring countries about China's implicit political intention. Do people view trading with China differently? In this article, we incorporate the political context of trade agreements by showing that trade with partners who come with political costs is less likely to be supported. Using a nationally representative survey experiment from Taiwan, we find that trading with China garners less support than trading with Japan or Malaysia, and nationalism suppresses self-interest when the proposed trading partner is China. We show that national attachment, which is neither a proxy for political identification nor a proxy for national chauvinism, becomes a stronger predictor of trade preferences toward China. While the political tension between China and Taiwan is unique, many countries see at least one other country posing a negative externality. Our finding suggests strongly identified nationalists would oppose engaging with a hostile outsider regardless of their self-interest.
What's law got to do with it? Is consumer law the solution to problems faced by student tenants?
Authors: Walsh Emily 
Published: April 2021

AbstractThis paper examines the extent to which law and regulation protects students renting from private individuals or private companies, as opposed to universities, in both of the main types of student accommodation, the private rented sector (PRS) and purpose-built student accommodation (PBSA). It first examines the different problems faced by students in both tenure types, notably issues of repair and the failure of PBSA providers to complete accommodation in time for the beginning of term. Secondly, it considers consumerisation of private renting and the extent to which a consumer protection law approach can assist tenants generally, and students specifically. Thirdly, the paper explains how power relationships between students and landlords and issues with access to legal advice restrict access to justice for student as tenants. It is argued that whilst consumer contract law and consumer protection law have something to offer student tenants (particularly in PBSA) a generic consumer approach to the rights of tenants is insufficient because the nature of the landlord and tenant relationship inhibits access to legal redress. It is concluded that in addition to improved consumer protections, a proactive approach by both local authorities and universities could significantly improve the experiences of students.
Neither-And Thinking: Understanding James March's Unique Solution to Paradox
Authors: Li Xin 
Published: April 2021

ABSTRACTIn this article, I propose a typology of thinking pattern that helps us understand the variants of the so-called ‘both/and thinking’ shared by many organizational paradox scholars in the West and China. The variants are distinguished by the ‘primary thinking-secondary thinking’ structure between the combined elementary thinking. One of the variants, i.e., Neither-And thinking, is associated with James March's discussion of logic of consequences and logic of appropriateness. An examination of March's writings reveals an additional ‘principle-practice’ structure underlining March's unique solution to paradox. Incorporating the ‘principle-practice’ structure into the proposed typology in turn helps us better understand the other variants of ‘both/and thinking’ such as ambidexterity, contingency, and Zhong-Yong. The typology shows March's Neither-And solution is unique because it embraces a primary neither/nor thinking while all the other variants do not. To demonstrate the value of March's unique solution, I apply Neither-And thinking characterized by the ‘principle-practice’ relationship to paradoxes outside organization studies, e.g., in Deconstruction, Buddhism, and quantum physics. The wide application of Neither-And thinking implies that James March's unique solution to organizational paradox may have provided a key to understanding paradox in general.

AbstractSCFA increase serotonin (5-hydroxytryptamine, 5-HT) synthesis and content in the colon in vitro and ex vivo, but little is known in vivo. We tested whether dietary indigestible saccharides, utilised as a substrate to produce SCFA by gut microbiota, would increase colonic 5-HT content in mice. Male C57BL/6J mice were fed a purified diet and water supplemented with 4 % (w/v) 1-kestose (KES) for 2 weeks. Colonic 5-HT content and enterochromaffin (EC) cell numbers were lower in mice supplemented with KES than those without supplementation, while monoamine oxidase A activity and mRNA levels of tryptophan hydroxylase 1 (Tph1), chromogranin A (Chga), Slc6a4 and monoamine oxidase A (Maoa) genes in the colonic mucosa, serum 5-HT concentration and total 5-HT content in the colonic contents did not differ between groups. Caecal acetate concentration and Bifidobacterium pseudolongum population were higher in KES-supplemented mice. Similar trends were observed in mice supplemented with other indigestible saccharides, that is, fructo-oligosaccharides, inulin and raffinose. Intragastric administration of live B. pseudolongum (108 colony-forming units/d) for 2 weeks reduced colonic 5-HT content and EC cell numbers. These results suggest that changes in synthesis, reuptake, catabolism and overflow of 5-HT in the colonic mucosa are not involved in the reduction of colonic 5-HT content by dietary indigestible saccharides in mice. We propose that gut microbes including B. pseudolongum could contribute to the reduction of 5-HT content in the colonic mucosa via diminishing EC cells.
Height and quality of life among older adults (50+) in India: a cross-sectional study

Published: April 2021

AbstractAdult height is a summary measure of health and net nutrition in early childhood. This study examines the association between height and quality-of-life outcomes in older adults (50+) in India. Cross-sectional data from Wave 1 of the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) conducted in 2007 were analysed. The association between height and quality of life was assessed using bivariate and multivariate logistic and linear regression models. The mean WHO quality-of-life score (WHO-QoL) increased from 45.2 among the older adults in the lowest height quintile to 53.2 for those in the highest height quintile. However, the prevalence of self-rated poor quality of life declined from 16.4% in the lowest height quintile to 6.1% in the highest height quintile. In the fully adjusted regression model, height was found to be positively associated with quality-of-life outcomes among both men and women, independent of socioeconomic and physical health confounders. The association was particularly strong for women. Women in the highest height quintile had a 2.65 point higher WHO-QoL score than those in the lowest height quintile. Similarly, the likelihood of reporting a poor quality of life was lower among women in the highest height quintile. Furthermore, measures of economic status, handgrip strength, cognitive ability and poor self-rated health were significantly associated with WHO-QoL and self-rated poor quality of life. Overall, this study revealed a significant association between height and quality of life among older adults in India, suggesting a significant role of childhood circumstances in quality of life in later life.

AbstractOf the five nominal species in the genusCaranxLacepède 1801 distributed throughout the Eastern Central Pacific,Caranx caballusandCaranx sexfasciatusare the only two that have formal fish larval descriptions based on diagnostic characteristics (morphology, meristics and pigmentation). In this study, the diagnostic characteristics of threeCaranxspecies larvae were validated using DNA barcoding analysis cytochromecoxidase subunit I (COI; 651 bp). For the first time, the morphological taxonomic assignation ofC. caballusfish larvae was confirmed using COI gene partial sequences of adults, with a genetic similarity between 99.8–100%. However, molecular evidence demonstrated that fish larvae previously described asC. sexfasciatushad high genetic similarity (99.7–100%) and low genetic distance (<1%) toCaranx caninusadults. An undescribed larval morphotype collected in the present study genetically matched (100%) with COI sequences ofC. sexfasciatusadults. The diagnostic characteristics of this new morphotype were a lack of pigmentation in the supraoccipital crest, over the gut, and at the terminal region of the gut. The combination of diagnostic characteristics and DNA barcoding evidence allowed the discrimination and validation ofC. caballus,C. caninusandC. sexfasciatuslarvae. The diagnostic characteristics and COI sequences ofCaranx lugubrisandCaranx melampyguslarvae, which are also distributed in the Eastern Central Pacific, remain to be investigated.
Assessing the effectiveness of public awareness-raising initiatives for the Hainan gibbon Nomascus hainanus

Published: April 2021

AbstractMany protected areas conduct awareness-raising activities to increase local knowledge and support conservation programmes, but the effectiveness of such activities is rarely assessed. Public awareness-raising has been carried out since the early 2000s around Bawangling National Nature Reserve, Hainan, China, to improve conservation knowledge about the Critically Endangered Hainan gibbon Nomascus hainanus, one of the rarest mammals. We conducted 207 interviews in 25 villages around Bawangling National Nature Reserve to evaluate the outcome of previous conservation education, through comparison of variation in local respondent knowledge and attitudes, and specific enquiries about sources of knowledge acquisition. Likelihood of accurate responses to most of our questions regarding the species was positively correlated with local exposure to gibbon-themed billboards and murals, and respondents exhibited greater knowledge about several key conservation indices for gibbons compared to their knowledge about sympatrically occurring rhesus macaques Macaca mulatta. Many respondents specifically reported they knew about local existence, population size, conservation status, and threats to gibbons from past awareness-raising activities, with village education sessions and billboards widely identified as key sources of information. However, other known awareness-raising approaches have had little detectable effect on shaping local conservation awareness. Although educational activities have improved awareness about gibbons and their conservation requirements in relative terms, overall levels of knowledge remain low in many important areas and ongoing improvement of local awareness is still needed, in particular around poorly-understood topics such as gibbon conservation status, rarity and threats, and for socio-demographic groups possessing less conservation knowledge.

AbstractBackgroundThe goal of the present study was to investigate the association between PTSD and the onset of hypertension in previously normotensive individuals in a population living in the stressful environment of the urban slums while controlling for risk factors for cardiovascular disease (CVD).MethodsParticipants were 320 normotensive individuals who lived in slums and were attending a family doctor program. Measurements included a questionnaire covering sociodemographic characteristics, clinical status and life habits, the Posttraumatic Stress Disorder Checklist – Civilian Version, and the Beck Depression Inventory. Incident hypertension was defined as the first occurrence at the follow-up review of the medical records of (1) systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher, (2) the participant started taking antihypertensive medication, or (3) a new diagnosis of hypertension made by a physician. Differences in sociodemographic, clinical, and lifestyle characteristics between hypertensive and non-hypertensive individuals were compared using the χ2 and t tests. Multivariate Cox proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI).ResultsSix variables – age, educational level, body mass, smoking, diabetes, and PTSD diagnosis – showed a statistically significant (p ≤ 0.20) association with the hypertensive status. In the Cox regression, only PTSD diagnosis was significantly associated with incident hypertension (multivariate HR = 1.94; 95% CI 1.11–3.40).ConclusionsThe present findings highlight the importance of considering a diagnostic hypothesis of PTSD in the prevention and treatment of cardiovascular diseases.

AbstractBackgroundAuditory frequency modulation learning (‘auditory learning’) is a key component of targeted cognitive training (TCT) for schizophrenia. TCT can be effective in enhancing neurocognition and function in schizophrenia, but such gains require significant time and effort and elude many patients.MethodsAs a strategy to increase and/or accelerate TCT-induced clinical gains, we tested the dose- and time-course effects of the pro-attentional drug, amphetamine (AMPH; placebo, 2.5, 5 or 10 mg po; within-subject double-blind, order balanced) on auditory learning in schizophrenia patients [n = 32; M:F = 19:13; age 42.0 years (24–55)]. To understand predictors and/or mechanisms of AMPH-enhanced TCT, we also measured auditory fidelity (words-in-noise (WIN), quick speech-in-noise (QuickSIN)) and neurocognition (MATRICS comprehensive cognitive battery (MCCB)). Some measures were also acquired from age-matched healthy subjects (drug free; n = 10; M:F = 5:5).ResultsPatients exhibited expected deficits in neurocognition. WIN and QuickSIN performance at low signal intensities was impaired in patients with low v. high MCCB attention/vigilance (A/V) scores; these deficits were corrected by AMPH, maximally at 2.5–5 mg (d's = 0.79–1.29). AMPH also enhanced auditory learning, with maximal effects at 5 mg (d = 0.93), and comparable effects 60 and 210 min post pill. ‘Pro-learning’ effects of AMPH and AMPH-induced gains in auditory fidelity were most evident in patients with low MCCB A/V scores.ConclusionsThese findings advance our understanding of the impact of pro-attentional interventions on auditory information processing and suggest dose- and time-course parameters for studies that assess the ability of AMPH to enhance the clinical benefits of TCT in schizophrenia patients.

AbstractAim:Stereotactic ablative body radiotherapy (SABR) for spine metastases is associated with a risk of vertebral compression fracture (VCF). The aim of this study was to determine the rate of VCF at one UK institution and evaluate the use of the Spinal Instability Neoplastic Score (SINS) to predict these.Materials and methods:A retrospective analysis of all patients who underwent SABR for spinal metastases between 2014 and 2018 at one UK institution was performed. Basic demographic data were collected, and SINS prior to SABR was calculated. The primary outcome was VCF rate. Secondary outcomes included time to VCF and need for surgical intervention following VCF.Results:A total of 48 oligometastases were treated with a median follow-up of 20·5 months. A maximum of two vertebral bodies were treated. The median baseline SINS was calculated as 3. The median dose was 26 Gy in three fractions. Two patients were reported to have VCF and both were successfully conservatively managed.Findings:SABR for spine oligometastases is being performed safely with low VCF rates which are comparable with those in international publications. This may be as a result of strict adherence to criteria for delivery of SABR with low pre-treatment SINS.

Published: April 2021

AbstractAim:To compare the acute radiation-induced bowel and bladder toxicities of two hypofractionated radiotherapy (HFRT) regimens in localised prostate cancer (PCa).Materials and methods:This trial consists of patients with histologically confirmed stage T1-T3aN0M0 PCa, a prostate-specific antigen concentration of 40 ng/mL or lower, and Eastern Cooperative Oncology Group performance status of 0–2. Participants were randomly assigned (1:1) to 56 Gy in 16 fractions over 4 weeks (arm A) or 70·2 Gy in 26 fractions over 5 weeks (arm B). Acute bowel and bladder toxicities were assessed using Radiation Therapy Oncology Group criteria.Results:Between June 2018 and December 2019, 40 patients were randomly assigned to treatment with 4-week (n = 20) and 5-week HFRT (n = 20). In the third month after completion of radiotherapy, the cumulative incidence of acute bowel and bladder toxicities of arms A and B was 20 versus 5% and 70 versus 85%, respectively. The cumulative incidence of grade 2 or worse bowel and bladder toxicities of the 5-week regimen was non-inferior to 4-week HFRT [bowel toxicity: 5% (arm A) versus 5% (arm B), bladder toxicity: 50% (arm A) versus 60% (arm B), p = 0·52).Findings:The 5-week regimen of HFRT is non-inferior to 4-week HFRT in terms of acute bowel and bladder toxicities.
Trade Law in a Data-Driven Economy: The Need for Modesty and Resilience
Authors: Shaffer Gregory 
Published: April 2021

AbstractThis article examines the social challenges posed by the data-driven economy, their implications for international trade law, the current trade negotiating context involving distinct models advanced by the United States, European Union, and China, and a way forward that can both enhance trade and regulatory efficacy. It examines seven interrelated risks. They are the rise of ‘winner-take-all’ companies; social control through public and private surveillance; social polarization; premature deindustrialization; national security threats; cybersecurity risks; and threats to personal privacy. In response to these risks, the article contends that trade agreements should be deferential to national regulation, while supporting mechanisms for regulatory learning and adaptation. In this spirit, the article advances a governance framework that goes beyond ‘liberalization' and that foregrounds the importance of building resilience and engaging in regulatory problem solving.
Whispering-gallery microlasers for cell tagging and barcoding: the prospects for in vivo biosensing

Published: April 2021

AbstractResearchers in the field of whispering-gallery-mode (WGM) microresonators have proposed biointegrated low-threshold WGM lasers, to enable large-scale parallel single-cell tracking and barcoding. Although the reported devices have so far been primarily investigated in model applications, most recent results represent important steps towards the development of in vivo tags and sensors that utilize the unique and narrow spectral features of miniature WGM lasers.

Published: April 2021

AbstractAlthough trauma-focused cognitive behavioural therapy (TF-CBT) is the frontline treatment for posttraumatic stress disorder (PTSD), up to one half of patients do not respond optimally to this treatment. Inhibitory functions are important for successful management of PTSD, yet there is a dearth of knowledge regarding the extent to which neural mechanisms unpinning response inhibition are associated with TF-CBT response. Treatment-seeking PTSD patients (n = 40) were assessed during a response inhibition task (the Go/No-Go task) while undergoing functional magnetic imaging (fMRI) and event-related potentials (ERP) in separate sessions. PTSD symptom severity was assessed with the Clinician-Administered PTSD Scale, before undergoing nine sessions of TF-CBT. They were then reassessed post-treatment to estimate reduction in fear and dysphoric symptoms of PTSD. Although neural responses during the inhibitory task did not predict overall symptom change, reduced activation in the left precuneus and the right superior parietal cortex predicted greater improvement in dysphoric symptoms. ERP responses during response inhibition indicated that lower P3 peak latency predicted greater reduction of dysphoric symptoms. There were no significant predictors of changes of fear symptoms. These findings indicate that neural activity associated with response inhibition can act as a predictive biomarker of TF-CBT response for PTSD symptoms. This pattern of findings underscores the importance of delineating the role of biomarkers to predict remission of subtypes of PTSD.
