Differences in treatment strategies in the management of acute appendicitis in a county hospital in Guatemala and an academic teaching institution in the United States
Authors: Alejo Gabriela , Ruiz Maria , Hernandez-Ochoa Anny , Ortiz Cesar , Huerta Sergio
Published: December 2020

Laparoscopy and antibiotic-first (NOM) strategies have been introduced in the management of acute appendicitis in industrialised countries. Data regarding the feasibility of these strategies in low-income nations are sparse. A retrospective analysis of adult patients undergoing appendicectomy at a county non-teaching hospital in San Benito, Guatemala (Hospital Nacional (HNSB)) was compared to an academic, teaching institution in Dallas, USA (Veterans Medical Centre). Most patients at the VA (92%) underwent computed tomography prior to being operated upon while none did so at HNSB. Whilst all patients at HNSB underwent an open approach, 95% of VA patients underwent a laparoscopic appendicectomy with a 4.7% conversion rate. General anaesthesia was universally used at Veterans Medical Centre, whilst spinal anaesthesia was utilised in 88% of cases at HNSB. NOM of acute appendicitis was undertaken only rarely at the Veterans Medical Centre and never at HNSB, where it was not thought expedient.
Complex open sternal fracture with impingement of the pericardium
Authors: Tiwari Sandeep , Singh Anita , Bhandari Paras , Ghatak Debmoy , Agarwal Harshit
Published: December 2020

The incidence of sternal fracture ranges from 3 to 8%. In more than half, they are associated with other organ trauma such as blunt cardiac injuries, rib, scapular or vertebral fractures. Hence, the presence of sternal fracture is considered a marker for significant transmission of energy. The management of isolated sternal fractures is usually non-operative with surgery reserved for displaced fractures or in cases of respiratory insufficiency. However, management may become challenging when they are associated with other significant trauma. We discuss a case of sternal fracture complicated by the presence of blunt cardiac injury, open pneumothorax, rib fractures, anterior flail chest and empyema.
Malaria among migrants in a university hospital in Colombia during 2018: A case series
Authors: Carreño-Almánzar Fabián R , Coronado-Galán Adán , Cala-Gómez Sonia A , Vega-Vera Agustín
Published: December 2020

Imported malaria has increased in Colombia since 2015 and has been attributed to migrants coming from Venezuela. We present a series of malaria cases, nested in a retrospective cross-sectional study between 2017 and 2018, aimed at calculating the prevalence of medical diseases among immigrants in a University Hospital in Colombia. Among 154 immigrants admitted for medical causes between 2017 and 2018, 8 were diagnosed with malaria, all due to Plasmodium vivax. Of these, seven had uncomplicated malaria, five had a previous history of malaria, one was critically ill, but none died. We highlight that, similar to other case series of imported malaria, Latin American migrants were young, with similar clinical profiles, having a low proportion of severe cases, and P. vivax was the most frequent cause.
Personality Rights in China’s New Civil Code: A Response to Increasing Awareness of Rights in an Era of Evolving Technology
Authors: Wang Liming , Xiong Bingwan
Published: December 2020

This article explores and assesses the significance of the adoption of a separate part (or, book 编) on personality rights in China’s new Civil Code. We argue that there are profound socioeconomic meanings underlying the technical changes in the classic structure of the civil codes in civil law tradition. On one hand, the stand-alone part on personality rights is the fruit and embodiment of the rising rights consciousness of personality in Chinese civil society, which has been largely unexplored in existing China studies. On the other hand, the part provides a new legislative model to comprehensively tackle the pervasive technological challenges to the protection of personal spheres, which is entangled with the rising rights consciousness over personality in China. Yet, the robustness of the acknowledgment of personality rights in this special part in promoting the protection of such rights remains to be tested in future court judgments.
To V or Not to V: Contingencies of Going Vegan
Authors: Waters Corey
Published: December 2020

This study examines mobilization processes with a particular focus on how people come to contemplate and embrace or reject veganism. Engaging the narratives of 33 interview participants who interacted with vegan advocacy networks in Greater Philadelphia, the study accounts for how prospective vegans negotiate forces, such as social networks and ties, that activate or hinder their mobilization; and for how they prioritize veganism among other priorities. Among other manners, participants came to contemplate the prospect of becoming vegan upon recognizing veganism as congruent with their other priorities. Participants who became vegan were more likely than participants who did not to prioritize altruism, to seek information that motivated and empowered them, and to deploy strategies to attenuate antagonism. The study’s findings suggest that participation in food movements is contingent on how prospective participants prioritize, on the incentives and mindset with which they contemplate participation, and on their capacity to participate.
Relationship 2.0: A systematic review of associations between the use of social network sites and attachment style
Authors: Stöven Lynne Marie , Herzberg Philipp Yorck
Published: December 2020

Today, Social Network Sites (SNSs) offer a wide variety of functions for initiating and maintaining personal relationships (i.e. sharing private information, messaging, commenting, liking or viewing others profiles). According to the uses and gratifications approach, individuals chose how they use media in order to satisfy given needs. Regarding personal relationships, attachment style is associated with distinct needs and behaviors. Thus, SNS use should differ with distinct attachment styles. This review aims to answer the question, how attachment style is related to SNS usage pattern and provide a comprehensive overview, by identifying and integrating associations with different facets of SNS use. Results were based on a systematic review of 17 studies. Measures of SNS use could be attributed to the facets of three categories: (1) Quantitative use (i.e. time spent on SNSs, number of friends/followers), (2) qualitative use (social use, parasocial use, self-presentation, monitoring) and (3) SNS motive (anxiety reduction, avoiding closeness). Especially insecure attached individuals strive to satisfy attachment needs through SNS use. While anxious individuals aim to reduce anxiety i.e. by seeking feedback via online social interaction, avoidant users can feel connected browsing others’ profiles without facing the threat of closeness. Insecure attachment was associated with negative outcomes related to SNS use, such as addictive behaviors. Limitations and implications of the findings are discussed.
Diaphragmatic weakness after transcatheter arterial chemoembolization of the right inferior phrenic artery for treatment of hepatocellular carcinoma: a comparison of outcomes after N-butyl cyanoacrylate versus gelatin sponge embolization
Authors: Noh Seung Yeon , Gwon Dong Il , Park Suyoung , Yang Woo Jin , Chu Hee Ho , Kim Jong Woo
Published: December 2020

Background

The inferior phrenic artery (IPA) is the most common extrahepatic feeder for hepatocellular carcinoma (HCC) during transhepatic arterial chemoembolization (TACE).

Purpose

To compare the incidence of diaphragmatic weakness in patients with HCC after TACE of the right IPA conducted using either N-butyl cyanoacrylate (NBCA) or gelatin sponge particles.

Material and Methods

Medical records of 111 patients who underwent TACE of the right IPA using NBCA were retrospectively reviewed and compared with data from 135 patients with IPA embolization using gelatin sponge particles.

Results

The incidence of diaphragmatic weakness after the initial TACE procedure did not significantly differ between the groups (NBCA group 16.2%; gelatin sponge group 20.7%; P = 0.458). Five patients in the NBCA group and 11 in the gelatin sponge group showed spontaneous resolution of diaphragmatic weakness after a mean period of 3.5 months. Diaphragmatic weakness developed after the initial follow-up visit in 17 patients from the gelatin sponge group due to repeated TACE of the right IPA (mean 2.4 sessions; range 2–4 sessions), while it spontaneously developed without additional TACE procedures in one patient from the NBCA group. Permanent diaphragmatic weakness was less common in the NBCA than in the gelatin sponge group (12.6% and 25.2%, respectively; P = 0.017). The complete response rate did not significantly differ between the groups (NBCA group 16.2%; gelatin sponge group 25.9%; P = 0.065).

Conclusion

Use of NBCA rather than gelatin sponge particles for TACE of the right IPA resulted in a lower incidence of permanent diaphragmatic weakness.
Shaping Physical, Economic, and Policy Components of the Food Environment to Create Sustainable Healthy Diets
Authors: Drewnowski Adam , Monterrosa Eva C. , de Pee Saskia , Frongillo Edward A. , Vandevijvere Stefanie
Published: December 2020

Background:

Sustainable healthy diets are those dietary patterns that promote all dimensions of individuals’ health and well-being; have low environmental pressure and impact; are accessible, affordable, safe, and equitable; and are culturally acceptable. The food environment, defined as the interface between the wider food system and consumer’s food acquisition and consumption, is critical for ensuring equitable access to foods that are healthy, safe, affordable, and appealing.

Discussion:

Current food environments are creating inequities, and sustainable healthy foods are generally more accessible for those of higher socioeconomic status. The physical, economic, and policy components of the food environment can all be acted on to promote sustainable healthy diets. Physical spaces can be modified to improve relative availability (ie, proximity) of food outlets that carry nutritious foods in low-income communities; to address economic access certain actions may improve affordability, such as fortification, preventing food loss through supply chain improvements; and commodity specific vouchers for fruits, vegetables, and legumes. Other policy actions that address accessibility to sustainable healthy foods are comprehensive marketing restrictions and easy-to-understand front-of-pack nutrition labels. While shaping food environments will require concerted action from all stakeholders, governments and private sector bear significant responsibility for ensuring equitable access to sustainable healthy diets.
Territorial and Sustainable Healthy Diets
Authors: Hachem Fatima , Vanham Davy , Moreno Luis A.
Published: December 2020

The rapid changes that societies have gone through in the last few decades have led to the increase in the prevalence of malnutrition in all its forms and to the degradation of natural resources and the environment. The change in the dietary habits and production systems are responsible for much of this change. Some territorial diets have been shown as potentially capable of reversing these trends by positively contributing to the health of people and the environment such as the Mediterranean Diet and the New Nordic Diet. In this paper, we review the contribution of these 2 diets to health and nutrition and to environmental, sociocultural, and economic sustainability proposing pertinent indicators. Learning from a culturally established diet and a constructed one, tradeoff could be reached to ensure better health and sustainability outcomes. Strong factors for achieving this goal lie in building on the sociocultural appropriation of diets, having the proper tools and indicators, investing in cross-sector collaboration and policy coherence, and having the necessary political support to push the agenda of sustainability forward.
GPS Tracking Technologies to Measure Mobility-Related Behaviors in Community-Dwelling Older Adults: A Systematic Review
Authors: Chung Jane , Sargent Lana , Brown Roy , Gendron Tracey , Wheeler David
Published: December 2020

Global positioning system (GPS) technology has been increasingly used in aging research as a tool for reliably capturing the level and patterns of mobility among older adults. This article aims to systematically review the current state of GPS-based mobility research with community-dwelling older adults. Twenty-nine studies from 2008 to 2019 are included. Included studies examined various forms of temporal and spatial mobility measures. This review provides a synthesis of the current evidence on the risk factors or correlates of GPS-driven mobility limitations, such as demographic, cognitive, physical, psychological, and environmental factors. There is variability in types of GPS technology and GPS-derived mobility measures, GPS recording methods, data processing, and correlates of mobility limitation across studies. Future research should focus on identifying meaningful GPS-derived mobility measures and developing standardized protocols for GPS administration and data analytics for comparison across studies.
Rates of Presentation, Treatments and Serious Neurologic Disorders Among Children and Young Adults Presenting to US Emergency Departments With Headache
Authors: Ramgopal Sriram , Zhou Amy Z. , Hickey Robert W. , Marin Jennifer R.
Published: December 2020

Objective:

To evaluate rates of presentation, neuroimaging, therapies, and serious neurologic disorders (SNDs) among children and young adults presenting to the emergency department with headache.

Methods:

We performed a cross-sectional study of a nationally representative sample survey of visits to US emergency departments between 2002 and 2017. We identified encounters of patients ≤25 years old with chief complaint of headache. We report the rates of presentation, imaging, and treatments and report proportions having concomitant diagnoses of serious neurologic disorders.

Results:

Among encounters ≤25 years, 2.0% had a chief complaint of headache, with no change in the yearly rates of encounters ( P = .98). Overall, 20.8% had a head computed tomography (CT), with a reduction in performance between 2007 and 2016 ( P < .01). One-quarter (25.2%, 95% confidence interval [CI] 22.2%-28.3%) were given narcotics and 2.5% (95% CI 1.7%-3.2%) had serious neurologic disorders.

Conclusion:

Overall, 2.0% of emergency department encounters among patients ≤25 years were for headache, with low rates of serious neurologic disorders. CT use appeared to be declining.
Epilepsy-Related Outcomes in Children With Neonatal Cerebellar Injury
Authors: Seese Ronald R. , Cummings Dana D.
Published: December 2020

Objective:

Acute brain injury is a frequent perinatal neurologic complication that can involve the cerebellum. Although short-term outcomes of infants with neonatal cerebellar injury are well described, neurologic sequelae in older children are underreported. Here, we describe epilepsy-related outcomes in young children who suffered from neonatal cerebellar injuries.

Methods:

In-house automated software identified patients with neonatal brain injuries who were evaluated at our institution both as neonates (≤28 days) and as children (≥1 year). Neonatal hospital course, neuroimaging, and outcomes related to epilepsy were reviewed from the medical record. Patients were stratified into 2 groups based on neonatal brain injuries: those with cerebellar injury and those without cerebellar involvement.

Results:

Of the 282 neonates followed through childhood over the decade-long study period, 33 (12%) experienced neonatal brain injury. All 33 cases involved supratentorial injury, and 5 (15%) also included cerebellar injury. The development of epilepsy was significantly less likely in the group with cerebellar involvement (40%) compared to that with cerebellar sparing (82%; P = 0.043). In some cases, children with cerebellum-sparing injuries required admission for seizure control and developed drug-resistant epilepsy as well as status epilepticus. These outcomes occurred less frequently in the group with cerebellar involvement.

Conclusions:

Epilepsy-related sequelae may occur less frequently when the cerebellum is involved in neonatal brain injury. Larger prospective studies are needed to clarify how cerebellocortical networks impact functional brain connectivity and epilepsy longitudinally.
Historical droughts in Southeast Australia recorded in a New South Wales stalagmite
Authors: Scroxton Nick , Walczak Maureen , Markowska Monika , Zhao Jian-xin , Fallon Stewart
Published: December 2020

The Murray Darling Basin contains 40% of Australia’s farms and is subject to multi-year droughts that put severe pressure on southeast Australia’s freshwater resources. Yet the long-term frequency, timing and potential severity of these droughts is unknown, as there are few high-resolution paleoclimate records from the basin that extend past the instrumental era. In this study, we investigate the potential of stalagmites from Careys Cave, Wee Jasper, in the Murray-Darling Basin to record past droughts. We use a multiproxy approach of stalagmite stable isotopes, trace element data, and climate reanalysis. We show that (a) stalagmite δ18O at this site likely records either local or regional precipitation amount and (b) stalagmite δ18O shows reasonable coherence with decadal-scale wet and dry changes in regional rainfall over the last 150 years, including the Federation Drought (1895–1902). Therefore, stalagmites from Wee Jasper can be used to draw regional inferences about past rainfall and have potential to extend the record of past droughts in the Murray Darling Basin beyond the limits of historical data. Extracting such a record will enable a better understanding of the causes of multi-year droughts in the region and consequently better planning, mitigation, and resilience in the basin.
Stock Returns and Valuation Ratios at Sector Level in South Africa: The Regime-switch Modelling Approach
Authors: Chipunza Kudakwashe Joshua , Muguto Hilary Tinotenda , Muguto Lorraine , Muzindutsi Paul-Francois
Published: December 2020

There is mounting evidence of stock return predictability based on valuation ratios across various stock markets. Most studies in this regard assume that the link between stock returns and valuation ratios is constant and linear. Yet, return predictability may vary according to the prevailing market regime. Accordingly, this study investigated whether the dividend and price-earnings valuation ratios predict returns on six sector indices on the Johannesburg Stock Exchange and whether that predictability is dependent on the prevailing market regime. The study employed a Markov regime-switching model over a sample period spanning from 1996:01 to 2018:12. The results showed that in most sectors, predictability was present, and its significance was dependent on whether the market was in a bullish or bearish regime. These findings are useful to investors who use valuation ratios to predict returns and adjust portfolios in various sectors across different market regimes on the South African market.
Hashtag Activism, Politics and Resistance in Africa: Examining #ThisFlag and #RhodesMustFall online movements
Authors: Sebeelo Tebogo B.
Published: December 2020

The article examines the impact of digital technologies as emerging platforms for social activism in sub-Saharan Africa. Even though the African continent still lags behind in smartphone ownership and internet connectivity compared to other regions of the world, there is enough evidence to suggest that online-based movements have fundamentally transformed political engagement in Africa. This article uses the cases of hashtag activisms #ThisFlag (Zimbabwe) and #RhodesMustFall (South Africa), to demonstrate that social media has accentuated resistance in Africa. Particular attention is directed to the unique ways in which online-based movements have been used to enact resistance. The article provides critical insights into the centrality of context in the discussion of social media efficacy. State response and the promise of social media activism as foci for resistance is further outlined in the article.
Musical features that aid sleep
Authors: Dickson Gaelen Thomas , Schubert Emery
Published: December 2020

Background:

Music is thought to be beneficial as a sleep aid. However, little research has explicitly investigated the specific characteristics of music that aid sleep and some researchers assume that music described as generically sedative (slow, with low rhythmic activity) is necessarily conducive to sleep, without directly interrogating this assumption. This study aimed to ascertain the features of music that aid sleep.

Method:

As part of an online survey, 161 students reported the pieces of music they had used to aid sleep, successfully or unsuccessfully. The participants reported 167 pieces, some more often than others. Nine features of the pieces were analyzed using a combination of music information retrieval methods and aural analysis.

Results:

Of the pieces reported by participants, 78% were successful in aiding sleep. The features they had in common were that (a) their main frequency register was middle range frequencies; (b) their tempo was medium; (c) their articulation was legato; (d) they were in the major mode, and (e) lyrics were present. They differed from pieces that were unsuccessful in aiding sleep in that (a) their main frequency register was lower; (b) their articulation was legato, and (c) they excluded high rhythmic activity.

Conclusion:

Music that aids sleep is not necessarily sedative music, as defined in the literature, but some features of sedative music are associated with aiding sleep. In the present study, we identified the specific features of music that were reported to have been successful and unsuccessful in aiding sleep. The identification of these features has important implications for the selection of pieces of music used in research on sleep.
Staying Afloat: Planning and Managing Climate Change and Sea Level Rise Risk in Florida’s Coastal Counties
Authors: Hines Robert E. , Grandage Andrew J. , Willoughby Katherine G.
Published: December 2020

Climate change and sea level rise present significant risks to coastal governments’ fiscal and service solvency. Current lack of focus on climate change by the U.S. federal and some state governments pressures coastal governments to develop tractable solutions to manage localized risks. This research integrates adaptive governance and capital planning literatures to develop an adaptive risk management framework. Heeding the call for research of coastal county actions to plan for and respond to climate change, we conduct content analysis of planning documents, financial reports, meeting minutes, media reports, and other documentation of all coastal counties in Florida to quantify government efforts to address climate change. Risk management practices are hierarchically categorized by focus area, risk type, and tactic and placed within the adaptive risk management process framework. A well-functioning adaptive risk management process can redefine vague climate change risks into knowable, tractable problems to address.
New or Worsened Mitral Regurgitation After Surgical Aortic Valve Replacement: A Systematic Review
Authors: Kumar Nicolas , Kumar Julia E. , Hussain Nasir , Gorelik Leonid , Essandoh Michael K. , Whitson Bryan A. , Bhatt Amar M. , Flores Antolin S. , Hachem Ali , Sawyer Tamara R. , Iyer Manoj H.
Published: December 2020

Background

New or worsened mitral regurgitation (MR) is an uncommon yet serious complication after surgical aortic valve replacement (SAVR). While there have been numerous reports of its occurrence, there is little consensus regarding its presentation and management. This systematic review summarizes the evidence in the current literature surrounding new or worsened MR after SAVR and analyzes its potential implications.

Methods

Databases were examined for all articles and abstracts reporting on new or worsened MR after SAVR. Data collected included number of patients studied; patient characteristics; incidences of new or worsened MR; timing of diagnosis; and treatment.

Results

Thirty-six full-text citations were included in this review. The prevalence of new or worsened MR after SAVR was 8.4%. Sixteen percent of new MR occurrences were from an organic etiology, and 83% of new MR occurrences were that of a functional etiology. Most diagnoses were made in the late or unspecified postoperative period using echocardiography (range: 0 minutes to 18 years postoperatively). While no patients died from this complication, 7.7% of patients (16 out of 207) required emergent procedural re-intervention.

Conclusions

This systematic review underscores the importance of identifying new or worsened MR following SAVR and accurate scoring of MR severity to guide treatment. It also outlines the associated clinical measures commonly documented following this complication, and the usefulness of transesophageal echocardiography for the detection of significant MR. These results reflect the current, limited state of the literature on this topic and warrant further investigation into MR detection and management strategies in SAVR patients.
Economic uncertainty and tourism consumption
Authors: Nguyen Canh Phuc , Thanh Su Dinh , Nguyen Bach
Published: December 2020

This study examines the influence of economic uncertainty on tourism. The key hypothesis to test is that while economic uncertainty reduces outbound tourism, it may boost domestic tourism due to the economic-stagnant effects. Utilizing the framework of the theory of reasoned action to analyze a global sample of 124 countries over the period 1996–2017, we find some initial evidence showing that an increase in economic uncertainty encourages domestic tourism while reducing outbound tourism in the global sample. Notably, while these effects are consistent in the upper-middle-income economies, an increase in uncertainty has a positive impact on both domestic and outbound tourism in lower-middle-income economies and a negative impact on both domestic and outbound tourism in higher-income economies. The key implementation of this study is that tourism development is not always associated with economic development and stability; sometimes it could be a signal of economic stagnancy and inactiveness.
Digital placemaking and networked corporeality: Embodied mobile media practices in domestic space during Covid-19
Authors: Hardley Jess , Richardson Ingrid
Published: December 2020

In contemporary life, the mobile phone is integral to digital and material placemaking practices. In this article, drawing on ethnographic analysis conducted in Perth and Melbourne (Australia) in the first months of the coronavirus (Covid-19) pandemic, we explore how this relation has been recalibrated as an effect of ‘stay-at-home’ restrictions. We first provide a brief overview of our methodological and interpretative approach – drawing from postphenomenology as a useful framework for understanding the mobile–body–place relation and digital placemaking at home. Second, we consider how mobile media are ‘situated’ in the domestic environment. Third, through an analysis of participant narratives, we explore the concept of net locality (Gordon and de Souza e Silva (2011) through the lens of embodiment theory and suggest that the Covid-19 context has altered our experience of ‘networked corporeality’. Finally, we discuss the ambiguity of digital intimacy in the decoupling of mobile media and the body as a result of a rapid increase in both screen time and time spent at home. Throughout the article, we argue that mobile media use in the home is thoroughly enmeshed in the shifting boundaries of privacy, placemaking and domestic space. We question how the placemaking functionality of mobile media, the intimate body–technology relation specific to mobile media practices and ‘being-at-home’ were subsequently modified by physical distancing and isolation.
European Higher Education Students: Contested Constructions
Authors: Brooks Rachel , Abrahams Jessie
Published: December 2020

There are currently over 35 million students within Europe and yet, to date, we have no clear understanding of the extent to which understandings of ‘the student’ are shared across the continent. Thus, a central aim of this article is to investigate how the contemporary higher education student understands their own role, and the extent to which this differs both within nation-states and across them. This is significant in terms of implicit (and sometimes explicit) assumptions that are made about common understandings of ‘the student’ across Europe – underpinning, for example, initiatives to increase cross-border educational mobility and the wider development of a European Higher Education Area. Drawing on data from students across Europe – and particularly plasticine models participants made to represent their understanding of themselves as students – we argue that, in many cases, there is an important disconnect between the ways in which students are constructed within policy, and how they understand themselves. The models produced by participants typically foregrounded learning and hard work rather than more instrumental concerns commonly emphasised within policy. This brings into question assertions made in the academic literature that recent reforms have had a direct effect on the subjectivities of students, encouraging them to be more consumerist in their outlook. Nevertheless, we have also shown that student conceptualisations differ, to some extent, by nation-state, evident particularly in Spain and Poland, and by institution – most notably in England and Spain, which have the most vertically differentiated higher education systems. These differences suggest that, despite the ‘policy convergence’ manifest in the creation of a European Higher Education Area, understandings of what it means to be a student in Europe today remain contested.
The flipped classroom in second language learning: A meta-analysis
Authors: Vitta Joseph P. , Al-Hoorie Ali H.
Published: December 2020

Flipped learning has become a popular approach in various educational fields, including second language teaching. In this approach, the conventional educational process is reversed so that learners do their homework and prepare the material before going to class. Class time is then devoted to practice, discussion, and higher-order thinking tasks in order to consolidate learning. In this article, we meta-analysed 56 language learning reports involving 61 unique samples and 4,220 participants. Our results showed that flipped classrooms outperformed traditional classrooms, g = 0.99, 95% CI (0.81, 1.17), z = 10.90, p < .001. However, this effect had high heterogeneity (about 86%), while applying the Trim and Fill method for publication bias made it shrink to g = 0.58, 95% CI (0.37, 0.78). Moderator analysis also showed that reports published in non-SSCI-indexed journals tended to find larger effects compared to indexed ones, conference proceedings, and university theses. The effect of flipped learning did not seem to vary by age, but it did vary by proficiency level in that the higher proficiency the higher the effects. Flipped learning also had a clear and substantial effect on most language outcomes. In contrast, whether the intervention used videos and whether the platform was interactive did not turn out to be significant moderators. Meta-regression showed that longer interventions resulted in only a slight reduction in the effectiveness of this approach. We discuss the implications of these findings and recommend that future research moves beyond asking whether flipped learning is effective to when and how its effectiveness is maximized.
Populist contestations: Cultural change and the competing languages of sexual and gender identity
Authors: Cover Rob
Published: December 2020

There has been a vast proliferation of categories, descriptors and labels used to describe gender and sexual identity over the past few years, with terms now numbering in the hundreds. Many terms, such as heteroflexible, asexual, demigirl and sapiosexual actively contest masculine/feminine and hetero/homo binary arrangements of identity, and LGBTQ minority rights discourses and arguably represent an epochal shift in gender/sexual knowledge frameworks. The cultural conditions that make such change possible have yet to be explored. This paper draws on theoretical approaches to populism to analyse the role of popular culture, digital communication and contestation of institutional and expert knowledges in driving the emergence of new gender and sexual terminology.
Back in time for utopia: Neo-Victorian utopianism and the return to William Morris
Authors: Davidson Joe PL
Published: December 2020

When we think of the Victorian era, images of shrouded piano legs, dismal factories and smoggy streets often come to mind. However, the 19th century has been rediscovered in recent years as the home of something quite different: bold utopian visions of the future. William Morris’ great literary utopia News from Nowhere, first published in 1890, is an interesting case study in this context. Morris’ text is the point of departure for a number of recent returns to Victorian utopianism, including Sarah Woods’ updated radio adaptation of News from Nowhere (2016) and the BBC’s historical reality television series The Victorian House of Arts and Crafts (2019). In this article, I analyse these Morris-inspired texts with the aim of exploring the place of old visions of the future in the contemporary cultural imaginary. Building on previous work in neo-Victorian studies and utopian studies, the claim is made that the return to 19th-century dreams is a plural phenomenon that has a number of divergent effects. More specifically, neo-Victorian utopianism can function to demonstrate the obsolescence of old visions of utopia, prompt a longing for the clarity and radicality of the utopias of the Victorian moment, or encourage a process of rejuvenating the utopian impulse in the present via a detour through the past.
Analysis of seismic performance and research of load capacity of steel reinforced high strength concrete columns with rectangular helical hoops
Authors: Xue Jianyang , Zhang Xin , Ke Xiaojun
Published: December 2020

This paper mainly focused on the seismic performance and shear calculation method of steel reinforced high-strength concrete (SRHC) columns with rectangular helical hoops. An experimental investigation was performed in this paper. Eleven SRHC columns with rectangular helical hoops and one with ordinary hoops were constructed at the laboratory of Guangxi university. The failure modes, hysteresis loops, envelope curves, characteristic loads and displacements and cumulative damage analysis are presented and investigated. It can be seen from the test results that the failure modes of SRHC columns can be divided into three types with the shear span ratio increased, namely, shear baroclinic failure mode, flexure-shear failure mode and flexure failure mode. In addition, the specimens with rectangular helical hoops have plumper hysteretic loops. Shear span ratio is the main influencing factor of characteristic load; the axial compression ratio and concrete strength have less influence on characteristic load, while stirrup ratio has little effect on the characteristic load. Finally, a calculation method for shear capacity of SRHC columns under shear baroclinic failure and flexure-shear failure mode is proposed.
Learning about bodies and the lived consequences
Authors: Hornsey Richard , Gubby Laura
Published: December 2020

From the perspective of a final year physical education and sport and exercise science undergraduate student, this article explores the relationship between learned and lived experiences related to the body. The research uses an autoethnographic approach that focuses on the educational and social issues that the first author faced as his physical identity changed. The author reflects on the ways in which his once acceptable body experienced declining capital as his body became too ‘fat’ within the spaces that he was connected to. In an attempt to resist institutionalised understandings that imply that larger bodies are a result of neglect and poor lifestyle choices, this research demonstrates the impact of cultural understandings on the everyday life of a university student seeking an ‘acceptable body’.
Re-imagining the world: Australians’ engagement with postnationalism, or Why the nation is the problem
Authors: Fozdar Farida
Published: December 2020

Academic debate around the need for global cooperation, the anachronism of national borders, and the necessity of nurturing a cosmopolitan ethic of care for all, has strengthened over the last two decades, but it is unclear the extent to which the general population has embraced such ideas. This article explores Australians’ perspectives using data from a series of projects investigating whether Australians are moving beyond national to postnational orientations and cosmopolitan identifications. Quantitative data demonstrates robust nationalism, although elements of a postnational outlook are also evident. Discursive analyses similarly suggest that while compassion towards others and openness to difference do exist, the ideology of the nation-state remains strong, with postnational formations seen as impractical, and perceptions of the rights of others limited by nationalist thinking. The best characterisation of the Australian orientation is that of multicultural nationalism, an approach that celebrates internal diversity within limits, but remains hostile to postnational material formations and global cosmopolitan ideological formations.
Fostering self-regulated learning in higher education: Making self-regulation visible
Authors: Russell Joanne M , Baik Chi , Ryan Anna T , Molloy Elizabeth
Published: December 2020

Research associates self-regulated learning with academic achievement and lifelong learning. Although there is consensus surrounding the need for students to develop self-regulated learning skills, there is a paucity of research exploring how educators can foster student self-regulated learning. This study examines the teaching practices, beliefs and experiences of educators that foster student self-regulated learning, across a range of disciplines. It explores the characteristics of teaching that foster self-regulated learning, and the influences on educator approaches. Questionnaire and semi-structured interview data were subjected to analysis. The findings identified four types of teaching strategies used to foster self-regulated learning. This study illuminates the conditions that support educators to foster student self-regulated learning, as well as the challenges they face. Educators’ own engagement in self-regulation, often made visible to students, played a key role in promoting students’ self-regulatory capacities.

Objective:

This study aims to investigate the effect of dexmedetomidine on perioperative stress response and immune function in patients with tumors.

Methods:

Sixty patients who underwent selective radical gastrectomy for cancer were randomly divided into 3 groups: remifentanil group (group R), dexmedetomidine group (group D), and sufentanil group (group S). Remifentanil, dexmedetomidine, and sufentanil were used as general anesthetics. Endotracheal intubation and mechanical ventilation were performed after the spontaneous respiration disappeared. Then, the data were recorded, and blood samples were collected at all time points.

Results:

The heart rate significantly increased ( P < 0.05) at T1 in group S, and both heart rate and mean arterial pressure significantly increased ( P < 0.05) in group R when compared to group D. The heart rate significantly increased ( P < 0.05) at T2 in group S and group R. Furthermore, the heart rate significantly increased ( P < 0.05) at T3 and T4 in group S and group R. Intra-group comparison: The heart rate at T1–T4 and mean arterial pressure at T1–T4 significantly increased ( P < 0.05) in group S, and the heart rate at T1 and T4, and mean arterial pressure at T2–T4 significantly increased ( P < 0.05) in group R when compared to T0. The serum IL-6, IFN-γ, and β-EP significantly increased ( P < 0.05) at T0’ in group S and group R when compared to group D. Blood glucose, and serum IL-10, IFN-γ, and β-EP significantly increased ( P < 0.05), while IL-18 significantly decreased ( P < 0.05) at T1’ in group S and group R.

Conclusion:

Continuous infusion of dexmedetomidine in combination with the inhalation of sevoflurane is superior to sevoflurane + remifentanil or sufentanil in patients undergoing tumor surgery.
Cultures of Two Worlds: Štefka Cobelj’s Contribution to the Establishment of Museum Collections in Slovenia and Somalia
Authors: Petrovič Mira
Published: December 2020

Slovenian Štefka Cobelj (1923–1989) saw her work of an art historian and ethnologist as a calling, and dedicated her life entirely to it. She specialized in Baroque and Yugoslavian and international contemporary art, but was most passionate about world ethnology. As the director of the Ptuj museum in Slovenia, and later a museum consultant in Mogadishu in Somalia, she was involved in the creation of ethnology collections of national importance. On her numerous travels for both business and pleasure, she compiled a large personal collection of cultural, historical, and ethnological items. This article describes her contribution to the creation of collections in Ptuj and Mogadishu, and her personal heritage, which was bequeathed to the following Slovenian institutions: Celje Regional Museum, Maribor Art Gallery, Maribor Regional Museum, Ivan Potrč Library Ptuj, and Ptuj-Ormož Regional Museum.

Published: December 2020

Low energy availability (EA) can impair physiological function in athletes. The purpose of this study was to investigate EA status, metabolic status, and bone metabolism with biochemical analysis in Korean male soccer players. Twelve male athletes (18–20 years) completed the study. Body composition and bone mineral density were measured using dual energy X-ray absorptiometry (DXA), while VO2 max was determined by an incremental exercise test. Blood samples were taken for bone marker and hormone analyses. Resting energy expenditure (REE) was measured using the Douglas bag method and predicted using the DXA method. Food diaries and heart rates (HR) during training were recorded, and the Profile of Mood States 2 and Eating Attitude Test 26 were completed. Group differences between low EA (LEA <30 kcal/kg FFM/d, n = 5) and high EA (HEA ≥30 kcal/kg FFM/d, n = 7) were evaluated. The mean EA of the all participants was 31.9 ± 9.8 kcal/kg FFM/d with only two participants having an EA above 45 kcal/kg FFM/d. LEA showed suppressed REE (LEA: 26.0 ± 1.7 kcal/kg/d, HEA: 28.8 ± 1.4 kcal/kg/d, p = .011) with a lower REEratio (LEA: 0.91 ± 0.06, HEA: 1.01 ± 0.05, p = .008) as well as a lower insulin-like growth factor 1 (IGF-1) level (LEA: 248.6 ± 51.2 ng/mL, HEA: 318.9 ± 43.4 ng/mL, p = .028) compared to HEA. There were no group differences in bone markers or other hormone levels. Korean male athletes exhibited low EA status with suppressed metabolism, but there was limited evidence on the effect of EA on bone metabolism, endocrine system, and psychological parameters.
Psychosocial Factors Are Associated With Risk Acceptance in Upper Extremity Patients
Authors: Fatehi Amirreza , Ring David , Reichel Lee M. , Vagner Gregg A.
Published: December 2020

Background

Patients who help choose their health strategies are more adherent and achieve better health. An important role of the clinician is to verify that a patient’s expressed preferences are consistent with what matters most to the patient and not muddled by common misconceptions about symptoms or conditions. Patient choices are influenced by estimation of the potential benefits and potential harms of a given intervention. One method for quantifying these estimations is the concept of maximum acceptable risk (MAR), or the maximum risk that subjects are willing to accept in exchange for a given therapeutic benefit. This study addressed the hypothesis that misconceptions due to unhelpful cognitive bias regarding pain are associated with risk acceptance among people seeking care for an upper extremity condition.

Methods

We invited 140 new adult patients visiting an upper extremity specialist to complete a survey including demographics, pain intensity, depression and anxiety symptoms, catastrophic thinking, activity limitations, and MAR. Trauma or nontrauma diagnosis was obtained from the treating clinician and recorded by the research assistant. We used bivariate and linear regression analyses to identify factors associated with MAR among this population.

Results

Accounting for potential confounding in multivariable analysis, higher MAR was associated with older age and greater catastrophic thinking.

Conclusions

Specialists can be aware that people with more unhelpful cognitive biases may be willing to take more risk. Vigilance for common misconceptions and gentle, incremental reorientation of those misconceptions can increase the probability that people will choose options consistent with what matters most to them.
A Multimodal Pain Management Regimen for Open Treatment of Distal Radius Fractures: A Randomized Blinded Study

Published: December 2020

Background

Adequate pain control is critical after outpatient surgery where patients are not as closely monitored. A multimodal pain management regimen was compared to a conventional pain management method in patients undergoing operative fixation for distal radius fractures. We hypothesized that there would be a decrease in the amount of narcotics used by the multimodal group compared to the conventional pain management group, and that there would be no difference in bone healing postoperatively.

Methods

Forty-two patients were randomized into 2 groups based on pain protocols. Group 1, the control, received a regional block, acetaminophen, and oxycodone. Group 2 received a multimodal pain regimen consisting of daily doses of pregabalin, celecoxib, and acetaminophen up until postoperative day (POD) #3. They also received a regional block with oxycodone for breakthrough pain.

Results

From POD#3 to week 1, there was a significant increase in oxycodone use in the study group correlating with the point in time when the multimodal regimen was discontinued. The shortened Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH) scores taken at 2 weeks postoperation showed a significantly lower average score in the study group compared to the control. There was no difference in bone healing.

Conclusions

The 2 regimens yielded similar pain control after surgery. The rebound increase in narcotic use after the multimodal regimen was discontinued, and significant difference in QuickDASH scores seen at 2 weeks postoperatively supported that multimodal regimens may not necessarily lead to decreased narcotic use in outpatient upper extremity surgery, but in the short term are shown to improve functional status.
