Annealing effects on the optical and electrochemical properties of tantalum pentoxide films
Authors: Ren Wei , Yang Guang-Dao , Feng Ai-Ling , Miao Rui-Xia , Xia Jun-Bo , Wang Yong-Gang
Published: March 2021

Tantalum pentoxide (Ta2O5) has attracted intensive attention due to their excellent physicochemical properties. Ta2O5 films were synthesized via electron beam evaporation (EBE) and subsequently annealed at different temperatures ranging from 300 to 900 °C. X-ray diffraction (XRD) results show that amorphous Ta2O5 thin films form from 300 to 700 °C and then a phase transition to polycrystalline β-Ta2O5 films occurs since 900 °C. The surface morphology of the Ta2O5 films is uniform and smooth. The resulted Ta2O5 films exhibit excellent transmittance properties for wavelengths ranging from 300 to 1100 nm. The bandgap of the Ta2O5 films is broadened from 4.32 to 4.46 eV by annealing. The 900 °C polycrystalline film electrode has improved electrochemical stability, compared to the other amorphous counterparts.

Published: March 2021

Recently, there has been much interest in applying the color changes of nano-patterned structures to sensor technology. However, the lithographic nano-patterning process is not environmentally friendly, and it is difficult to fabricate large areas of color due to limitations associated with this approach. In this study, we realized a highly tunable structural coloration based on a Fabry–Perot interferometer design that does not require nano-patterning processes. To increase the reflected color change according to the angle, a color element using an asymmetric metal–insulator–metal structure was applied, fabricated using silver–silicon dioxide–tin (Sn), respectively. Using the optical properties of Sn, we maximized the change in reflection color and realized three primary colors of subtractive color of cyan, magenta and yellow according to the angle of designed MIM structure. Theoretical and experimental results revealed that the color and intensity of the reflectance depended strongly on the angle of the reflective surfaces. The manufacturing process is simple and yields large surfaces of high quality. Based on this premise, we fabricated a soft robot capable of color camouflage, and an angle-detecting color sensor for inspecting the three-dimensional shape quality of curved glass with a high sensitivity of 1.8 nm/degree. In addition, we propose a shape evaluation method by color, spectrometry, and monochromatic light.
Optimization studies on turbidity removal from cosmetics wastewater using aluminum sulfate and blends of fishbone
Authors: Ovuoraye Prosper E. , Ugonabo Victor I. , Nwokocha Gina F.
Published: March 2021

This research is centered on the optimization of coagulation–flocculation treatment of cosmetic wastewater. It analyzes blends of fishbone (BFB) and aluminum-based coagulant (ABC) to determine the efficacy of BFB as a potential coagulant–flocculants aid at optimum conditions using response surface methodology (RSM). The experiment was carried out employing the standard nephelometric procedure at 1000 rpm stirring rate. The central composite design (CCD) was used to examine the interactions of pH, dosage, and settling time to maximize the turbidity removal efficiency of the ABC- and BFB-driven coag–flocculation. The optimal pH, dosage, and settling time for ABC were obtained as 10, 0.1 g/L, and 2 min, while pH 6, 0.4 g/L, and settling time of 4 min were recorded for BFB following the established quadratic model of the RSM. The removal efficiency of ABC and BFB plots 80% and 88%, respectively; this corresponds to 262 NTU and 288 NTU of removal from the wastewater at optimal conditions. The kinetics result indicated that the rate constant (Kf) 3 × 10−3 (L/g min) of BFB surpassed 5 × 10−5 (L/g min) recorded for ABC following second-order coag–flocculation reaction, with correlation coefficients (R2) values of 0.999 and 0.9985, respectively. The research also applied cost–benefit analysis for the determination of the efficacy of BFB. The figure obtained shows that the benefit of using BFB will save $5.50 compared to ABC based on this work. At optimal conditions, BFB satisfied the environmental protection agency pH standard for industrial wastewater discharge, promising coagulant–flocculants aid for industrial wastewater purification purpose and the preservation of the environment.
Barriers in Implementation of Wastewater Reuse: Identifying the Way Forward in Closing the Loop

Published: March 2021

The business case for circular economy in water management perspective has gain relevance in the recent times. By 2030, it is estimated that 160% of global total available water will be required to satisfy demand of anthropogenic-related activities and increasing waste-related water will be produced. Gaps on the conceptual framing of water reuse within supply chain management are clearly emerging and the demand for decision support systems helping at assessing effective water consumption in industrial setting is pressing. Despite the numerous local initiatives towards wastewater resource usage, barriers remain for its implementation in practice. Through a systematic review of previous studies in this field, the barriers towards the uptake of wastewater use in agriculture were classified according to the PESTEL (political, economic, social, technological, environmental and legal) framework. Alongside political and legal support, it is identified that for an economically and environmentally sustainable scheme for incentivising the deployment of feasible technologies, there is also a need to gain acceptance for wastewater usage in society in order to enhance the deployment of existing technological solutions. Addressing these factors in tandem can aid the development towards a circular economy for wastewater.
The Languages of Mainland Southeast Asia
Authors: Enfield N. J.
Published: March 2021

Mainland Southeast Asia is one of the most fascinating and complex cultural and linguistic areas in the world. This book provides a rich and comprehensive survey of the history and core systems and subsystems of the languages of this fascinating region. Drawing on his depth of expertise in mainland Southeast Asia, Enfield includes more than a thousand data examples from over a hundred languages from Cambodia, China, Laos, Malaysia, Myanmar, Thailand, and Vietnam, bringing together a wealth of data and analysis that has not previously been available in one place. Chapters cover the many ways in which these languages both resemble each other, and differ from each other, and the diversity of the area's languages is highlighted, with a special emphasis on minority languages, which outnumber the national languages by nearly a hundred to one. The result is an authoritative treatment of a fascinating and important linguistic area.
The Science of Consciousness
Authors: Harley Trevor A.
Published: March 2021

Consciousness concerns awareness and how we experience the world. How does awareness, a feature of the mental world, arise from the physical brain? Is a dog conscious, or a jellyfish, and what explains the difference? How is consciousness related to psychological processes such as perception and cognition? The Science of Consciousness covers the psychology, philosophy, and neuroscience of consciousness. Written for introductory courses in psychology and philosophy, this text examines consciousness with a special emphasis on current neuroscience research as well as comparisons of normal and damaged brains. The full range of normal and altered states of consciousness, including sleep and dreams, hypnotic and meditative states, anesthesia, and drug-induced states, as well as parapsychological phenomena and their importance for the science of consciousness is covered, as well as the 'higher' states and how we can attain them. Throughout the text attempts to relate consciousness to the brain.
Numerical study of geometric morphing wings of the 1303 UCAV
Authors: Nugroho B. , Brett J. , Bleckly B.T. , Chin R.C.
Published: March 2021

Unmanned Combat Aerial Vehicles (UCAVs) are believed by many to be the future of aerial strike/reconnaissance capability. This belief led to the design of the UCAV 1303 by Boeing Phantom Works and the US Airforce Lab in the late 1990s. Because UCAV 1303 is expected to take on a wide range of mission roles that are risky for human pilots, it needs to be highly adaptable. Geometric morphing can provide such adaptability and allow the UCAV 1303 to optimise its physical feature mid-flight to increase the lift-to-drag ratio, manoeuvrability, cruise distance, flight control, etc. This capability is extremely beneficial since it will enable the UCAV to reconcile conflicting mission requirements (e.g. loiter and dash within the same mission). In this study, we conduct several modifications to the wing geometry of UCAV 1303 via Computational Fluid Dynamics (CFD) to analyse its aerodynamic characteristics produced by a range of different wing geometric morphs. Here we look into two specific geometric morphing wings: linear twists on one of the wings and linear twists at both wings (wash-in and washout). A baseline CFD of the UCAV 1303 without any wing morphing is validated against published wind tunnel data, before proceeding to simulate morphing wing configurations. The results show that geometric morphing wing influences the UCAV-1303 aerodynamic characteristics significantly, improving the coefficient of lift and drag, pitching moment and rolling moment.
Experiencing default nudges: autonomy, manipulation, and choice-satisfaction as judged by people themselves
Authors: Michaelsen Patrik , Johansson Lars-Olof , Hedesström Martin
Published: March 2021

Criticisms of nudging suggest that nudges infringe on decision makers’ autonomy. Yet, little empirical research has explored whether people who are subjected to nudges agree. In three between-group experiments (N = 2083), we subject participants to contrasting choice architectures and measure experiences of autonomy, choice-satisfaction, perceived threat to freedom of choice, and objection to the choice architecture. Participants who received a prosocial opt-out default nudge made more prosocial choices but did not report lower autonomy or choice satisfaction than participants in opt-in default or active-choice conditions. This was the case even when the presence of the nudge was disclosed, and when monetary choice stakes were introduced. With monetary choice stakes, participants perceived the threat to freedom of choice as slightly higher in the nudge condition than in the other conditions, but objection to the choice architecture did not differ between the conditions. Taken together, our results suggest that default nudges are less manipulative and autonomy-infringing than sometimes feared. We recommend that policymakers include measures of choice experiences when testing out new interventions.
Mental health stigma in Ukraine: cross-sectional survey
Authors: Quirke Eleanor , Klymchuk Vitalii , Suvalo Orest , Bakolis Ioannis , Thornicroft Graham
Published: March 2021

Background and study objectives

This study aimed to assess among Ukrainian adults: (1) knowledge of mental disorders; (2) attitudes towards people with mental health disorders, and to the delivery of mental health treatment within the community; and (3) behaviours towards people with mental disorders.

Methodology

A cross-sectional survey of Ukrainian adults aged 18–60 was conducted. Stigma-related mental health knowledge was measured using the mental health knowledge schedule. Attitude towards people with mental health disorders was assessed using the Community Attitudes towards Mental Illness scale. The Reported and Intended Behaviour scale was used to assess past and future intended behaviour towards people with mental health disorders.

Results

Associations between gender, age, and educational level and the knowledge and attitudes measures were identified. There was evidence of a positive association between being male and positive intended behaviours towards people with mental health disorders [mean difference (MD) = 0.509, 95% confidence interval (CI) 0.021–0.998]. Older age was negatively associated with positive intended behaviours towards people with mental health disorders (MD = −0.017, 95% CI 0.0733 to −0.001). Higher education was positively associated with stigma-related mental health knowledge (MD = 0.438, 95% CI 0.090–0.786), and negatively associated with authoritarian (MD = 0.755, 95% CI 0.295–1.215) attitudes towards people with mental health problems.

Conclusion

Overall, the findings indicate a degree of awareness of, and compassion towards, people with mental illness among Ukrainian adults, although this differed according to gender, region, and education level. Results indicate a need for the adoption and scaling-up of anti-stigma interventions that have been demonstrated to be effective.

Published: March 2021

Traversodontidae is a group of Triassic herbivorous/omnivorous cynodonts that represents the most diversified lineage within Cynognathia. In southern Brazil, a rich fossil record of late Middle/mid-Late Triassic cynodonts has been documented, withExaeretodon riograndensisAbdala, Barberena, and Dornelles, 2002 andSiriusgnathus niemeyerorumPavanatto et al., 2018 representing two abundant and well-documented traversodontids. The present study provides a comparative analysis of the morphology of the nasal cavity, nasal recesses, nasolacrimal duct, and maxillary canals of both species using computed tomography, highlighting the changes that occurred in parallel to the origin of mammaliaforms. Our results show that there were no ossified turbinals or a cribriform plate delimiting the posterior end of the nasal cavity, suggesting these structures were probably cartilaginous as in nonmammaliaform cynodonts. Both species show lateral ridges on the internal surface of the roof of the nasal cavity, but the median ridge for the attachment of a nasal septum is absent.Exaeretodon riograndensisandS. niemeyerorumshow recesses on the dorsal region of the nasal cavity, which increase the volume of the nasal cavity, potentially enhancing the olfactory chamber and contributing to the sense of smell. On the lateral sides of the nasal cavity, the analyzed taxa show a well-developed maxillary recess. AlthoughE. riograndensisandS. niemeyerorumhave roughly similar nasal cavities, in the former taxon, the space between the left and right dorsal recesses of the nasal cavity is uniform along its entire extension, whereas this space narrows posteriorly inS. niemeyerorum. Finally, the nasolacrimal duct ofS. niemeyerorumis more inclined anteroposteriorly than inE. riograndensis.
Tipping the scale: the role of a national nutritional supplementation programme for pregnant mothers in reducing low birth weight and neonatal mortality in India

Published: March 2021

With over 1·3 million Anganwadi centres (AWC) (meaning ‘courtyard shelter’), the Indian government runs a nationwide intervention providing nutrition supplement to pregnant mothers to improve the health of their children. Using two successive rounds of the nationally representative cross-sectional National Family Health Survey data (collected during 2005–2006 and 2015–2016) of India, we assessed whether nutrition supplements given to pregnant mothers through AWC were associated with select child health indicators – extremely low birth weight (ELBW), very low birth weight (VLBW), low birth weight (LBW) and neonatal mortality (death during day 0–27) stratified by death during day 0–1, day 2–6 and day 7–27. A total of 148 019 children and 205 593 children were eligible for analysing birth weight and neonatal mortality, respectively. OR with 95% CI, estimated from multivariate logistic regression models, suggest that receipt of nutrition supplements was associated with decreased risk of VLBW (OR: 0·73, 95% CI 0·63, 0·83, P < 0·001), LBW (OR: 0·92, 95% CI 0·88, 0·96, P < 0·001), but not ELBW (OR: 0·80, 95% CI 0·56, 1·15, P = 0·226). Women who always received nutrition supplements during their pregnancy saw lower risk of death of their neonates (OR: 0·67, 95% CI 0·61, 0·73, P < 0·001), including death on day 0–1 (OR: 0·66, 95% CI 0·58, 0·74, P < 0·001), day 2–6 (OR: 0·69, 95% CI 0·58, 0·82, P < 0·001) and day 7–27 (OR: 0·68, 95% CI 0·53, 0·87, P = 0·002). Therefore, nutritional supplementation to pregnant mothers appears to be helpful in deterring various stages of neonatal mortality, VLBW and LBW, though it might not be effective in mitigating ELBW. Findings were discussed considering possible limitations of the study.
Transcriptional identification of differentially expressed genes during the prepupal–pupal transition in the oriental armyworm,Mythimna separata(Walker) (Lepidoptera: Noctuidae)

Published: March 2021

The oriental armyworm,Mythimna separata(Walker) is a serious pest of agriculture that does particular damage to Gramineae crops in Asia, Europe, and Oceania. Metamorphosis is a key developmental stage in insects, although the genes underlying the metamorphic transition inM. separataremain largely unknown. Here, we sequenced the transcriptomes of five stages; mature larvae (ML), wandering (W), and pupation (1, 5, and 10 days after pupation, designated P1, P5, and P10) to identify transition-associated genes. Four libraries were generated, with 22,884, 23,534, 26,643, and 33,238 differentially expressed genes (DEGs) for the ML-vs-W, W-vs-P1, P1-vs-P5, and P5-vs-P10, respectively. Gene ontology enrichment analysis of DEGs showed that genes regulating the biosynthesis of the membrane and integral components of the membrane, which includes the cuticular protein (CP), 20-hydroxyecdysone (20E), and juvenile hormone (JH) biosynthesis, were enriched. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated that DEGs were enriched in the metabolic pathways. Of these DEGs, thirty CP, seventeen 20E, and seven JH genes were differentially expressed across the developmental stages. For transcriptome validation, ten CP, 20E, and JH-related genes were selected and verified by real-time PCR quantitative. Collectively, our results provided a basis for further studies of the molecular mechanism of metamorphosis inM. separata.

John Lennon'sPlastic Ono Bandas ‘first-person music’: notes on the politics of self-expression in rock music since 1970
Authors: Tochka Nicholas
Published: March 2021

In late 1970, John Lennon began promoting his first post-Beatles solo album,Plastic Ono Band, which he described as ‘first-person music’ toRolling Stoneeditor Jann Wenner. This essay situates the album and two of Lennon's promotional interviews within an emergent politics of individualism in order to explore how self-expression became an aesthetic practice and critical value in rock music. The album's reception and promotion help reveal how key political values – on individualism, rebellion and self-expression – began to be newly articulated to certain kinds of rock musicians after 1970. By understanding that process of articulation, popular music scholars may consider the contradictory political consequences of the broader valorisation of ‘first-person music’ since the 1970s.
From rage to riches: swag and capital in the Tanzanian hip hop industry
Authors: Pierson Michael
Published: March 2021

This article traces how Tanzanian Bongo Flava hip hop has shifted from a politically conscious genre at the dawn of democratization and liberalization to its contemporary articulations, more commonly aligned with glamorous, geographically abstracted Western pop sensibilities. It argues that ‘swag’, as an intimately embodied and musically performed charisma, has served as a connective thread across political and economic transformations because of its capacity to generate phantasmatic deferrals to common experiences of dispossession. These fetishistic qualities mediate the attachments of artists and consumers within the splintering musical genre, holding open space to reach for a diversity of desired futures.
Challenges facing regional live music venues: A case study of venues in Armidale, NSW
Authors: Bennett Cary
Published: March 2021

This article draws from a wider research project undertaken in 2018 in Armidale, a small regional city in New South Wales (NSW) Australia, to explore the challenges commercial venues face in presenting and maintaining a regular live music programme. An analysis of the main themes suggests that the issues regional venues encounter are often qualitatively and/or quantitatively different from those facing their urban counterparts. This research found that regulatory issues, such as licensing, planning and noise, were not considered major impediments to regularly hosting live music. Rather, finding and accessing affordable quality bands in the numbers and styles needed to keep audiences coming to gigs, and getting audiences to regularly attend and spend money in the numbers needed to sustain the gigs, were identified as ongoing difficulties. Although venues in larger metropolitan cities are often confronted with similar problems, these are not the sort of issues that stand out in the research in this area. Rather the regulatory environment is emphasised. By drawing attention to the non-regulatory challenges regional venues face, important new avenues of research are opened up that will benefit live music scenes across Australia.
The logic of distinctions in the Hungarian jazz field: a case study
Authors: Havas Ádám
Published: March 2021

This study aims to make the contemporary Hungarian jazz field the focus of a sociological investigation, based on a critical reinterpretation of Bourdieu's relational theory of artistic fields. It aims to grasp the logic of symbolic distinctions by analysing the free/mainstream dichotomy. This dichotomy of historically constituted poles is understood as a system of structuring oppositions that play a decisive role in the position-takings and prestige-construction of jazz musicians. The analysis of qualitative data shows how different evaluations and interpretations of shared musical references are instrumentalised in order to occupy positions in the field. Further, this article argues that such a qualitative analysis of local jazz fields transcends the national context, since culturally hybrid jazz diasporas offer an excellent terrain for analysing how the circulation of transnational artistic references influences the cultural dynamism of local fields that are embedded within global networks of cultural production.
‘The Rains of Castamere’: medievalism, popular culture, and the music ofGame of Thrones
Authors: Cuenca Esther Liberman
Published: March 2021

This article closely examines the song ‘The Rains of Castamere’, from the television series Game of Thrones (2011–19), to draw broader conclusions about how ‘medieval’ music manifests in contemporary popular culture and how music for television has become increasingly important in the last few decades. This article argues for the relevance of ‘The Rains of Castamere’ in popular music from three perspectives: first, as a musical adaptation of the ‘medieval’ world of 'folk’ music popularised in George R.R. Martin's A Song of Ice and Fire novels (1996–); second, as a song embedded in the rich tradition of modern ‘medieval’ music, which itself is a modern reconstruction influenced by cinematic and literary tropes; and lastly, as a track that exemplifies the influence of fan culture in both shaping and responding to popular medievalist music.
The Salut les copains generation
Authors: Morin Edgar , Hawkins Peter , Lebrun Barbara
Published: March 2021

In Paris on 22 June 1963, the French youth magazine Salut les copains celebrated its first year in print by organising a free outdoor concert on the Place de la Nation. The artists headlining the gig were young male and female pop singers who had been propelled to the top of the French charts thanks to the regular broadcasting of their music on the show Salut les copains (on private radio station Europe 1 since 1959), and extensive coverage in the weekly magazine of the same name (since 1962). The 150,000-strong crowd at the concert exceeded all expectations, but also generated a sense of moral panic in the media as worried commentators speculated on the dangerous mindlessness of such ‘rhythmic’ music for impressionable French youngsters.
A CROSSLINGUISTIC STUDY OF THE PERCEPTION OF EMOTIONAL INTONATION
Authors: Cho Christine MoonKyoung , Dewaele Jean-Marc
Published: March 2021

Pitch perception plays a more important role in emotional communication in English than in Korean. Interpreting the semantic aspects of pitch levels therefore presents a challenge for Korean learners of English. This study investigated how 49 Korean learners of English perceived 20 English emotional utterances. Participants were asked to complete a congruency task in which they indicated whether the category of the semantic valence was congruent with the intonation type. They also described each emotional utterance by providing an adjective. The task results of Korean participants were compared with those of a control group of 49 Anglo-American students. Statistical analyses revealed that the incongruence between the semantic meaning and the intonation type interfered with American participants’ performance more than Korean participants. The adjective task results also showed that American participants were more attuned to the interplay between the semantic meaning and the intonation type than Korean participants.
On the (Im)possibilities of a Free Theatre: Theatre Against Development in Palestine
Authors: NICHOLSON RASHNA DARIUS
Published: March 2021

The focus of this article is a critical evaluation of the impact of international development and conflict-resolution funding on theatre in the Occupied Palestinian Territories. The article complicates the predominant narrative of theatre as ‘cultural resistance’ in conflict zones by historicizing the Ford Foundation's role in the institutionalization of Palestinian drama; delineating the effects of neo-liberal state building and development on Palestinian modes of performance; and subsequently, analysing the Freedom Theatre's imbrication in a normative, humanitarian logic. Aid, while ensuring the material conditions for the growth of the Palestinian performing arts, promoted a structural dependency that emptied the language of anti-colonial resistance of emancipatory potential, generating a soft, phantom sovereignty for the audience of the international community. By reimagining ‘freedom’ as liberation from a backward, conservative society, the language of the human rights industry and its attendant cultural economy spawns a spectral ‘cultural resistance’ where freedom and nationhood appear real and unreal – visions refracting, but not existing in, reality.
Performing Protest and Protesting Performance: The International Circuits of Touring Political Theatre
Authors: LEFFLER ELLIOT
Published: March 2021

From 1980 to 1981, the Baxter Theatre of Cape Town, South Africa, produced a multi-racial Waiting for Godot that garnered vastly different reactions in the various cities to which it toured. With a cast led by John Kani and Winston Ntshona, icons of anti-apartheid theatre, it was sometimes hailed as a scathing anti-apartheid polemic, sometimes admired for its ‘universality’, and in one case denounced and shut down by anti-apartheid activists as a piece of pro-apartheid propaganda. Based on both archival research and interviews, this essay investigates the artists’ intentions and the public's reception in order to illuminate how the international theatrical circuits dovetailed with international activist circuits, sometimes supporting one another, and occasionally tripping each other up.
Truth, Discussion, and Free Speech in On Liberty II
Authors: Macleod Christopher
Published: March 2021

In this article, I offer a reading of On Liberty II which focuses on the structural features of the argument that Mill presents. Mill's argument, I suggest, is grounded on an appeal to the value of truth, and is divided into three sub-arguments, treating true, false and partially true opinion respectively. In section 1, I consider what constraints the teleological orientation of Mill's argument places on the case he makes, before examining in section 2 what the division of Mill's argument into three exhaustive sub-arguments tells us about the nature of ‘discussion’ as Mill uses the term. I go on, in section 3, to suggest that although On Liberty II does not offer a defence of free speech in the broad sense in which the term is often now used, we should be optimistic about the chances of finding such a defence in On Liberty III.
The Birth of the Cultural Treaty in Europe's Age of Crisis
Authors: Martin Benjamin G.
Published: March 2021

Bilateral treaties are an age-old tool of diplomacy, but before the First World War they were only rarely applied to the world of intellectual and cultural relations. This article explores the process by which diplomatic agreements on intellectual and cultural exchange came instead to be a common feature of interwar European international relations by contrasting two types of agreements identified by period observers: ‘intellectual’ accords, typified by the agreements France signed in the 1920s, and ‘cultural’ treaties, advanced by fascist Italy in the 1930s. Comparing France and Italy's use of such agreements in Central-Eastern Europe reveals that Italy's fascist regime responded to the crises and opportunities of the interwar period by developing a distinctive model of ‘cultural treaty’ that applied state power to international cultural exchange, and mobilised the idea of ‘culture’ itself, in a new and influential manner.

Recurrent implantation failure (RIF) is considered to be one of the major limiting factors of assisted reproductive technology (ART) programme success. The current study focused on the investigation of matrix metalloproteinases (MMPs), tissue inhibitors of MMPs (TIMPs), cytokines and cell adhesion molecules in peripheral blood (PB) and follicular fluid (FF) obtained from 44 women aged between 25 and 39 years old and undergoing intracytoplasmic sperm injection (ICSI). These women were divided into two groups: 22 RIF women with embryo implantation failures after the transfer of at least four fresh or frozen–thawed good quality embryos in a minimum of three ICSI cycles, and 22 ICSI success women (controls) who achieved a clinical pregnancy at their first ICSI attempt. The PB and FF samples were obtained from each patient on the day of oocyte retrieval. MMP-1, -2, -3, -7, -9, TIMP-1, -2, vascular endothelial growth factor (VEGF), leukaemia inhibitory factor (LIF), vascular cell adhesion molecule 1 (VCAM1) and intercellular adhesion molecules 1 (ICAM1) were analyzed using enzyme-linked immunosorbent assay of PB and FF. Our results showed significant decreases in PB MMP-7 and PB VEGF in the RIF group compared with controls [281.11 (33–614) pg/ml vs 119.92 (27–441) pg/ml;P-value = 0.030] and [82.54 (25.94–210.20) pg/ml vs 30.93 (13.62–193.33) pg/ml;P-value = 0.022; respectively]. Receiver operating characteristic (ROC) curve analysis showed informative area under the curve values for PB MMP-7, as well as for PB VEGF, making them able to be proposed as biomarkers of the RIF. Therefore, circulating MMP-7 and VEGF seem to play an interesting role in embryo implantation inin vitrofertilization (IVF)/ICSI cycles and could be proposed as circulating biomarkers of the RIF. These results could be helpful for clinicians and patients to choose the best rescue strategy and treatment to minimize implantation failure in women undergoing IVF/ICSI procedures after the first attempt.

This article proposes that nearly all of the sculpted frieze of the Arch of Constantine in Rome, generally regarded as Constantinian, derives from a triumphal monument of Diocletian commissioned shortly after his Vicennalia in 303 CE. The basis of the argument is the sculptural technique evinced by the frieze, especially the separately-worked heads of the emperor in four of the frieze slabs, together with the missing legs and feet of several of the other figures. These anomalies suggest that much of the frieze was spoliated from another monument that had honored a different man; Diocletian is the only emperor whose career fits the iconography. A Diocletianic date for most of the frieze blocks necessitates a reconsideration of long-standing interpretations of the spolia on the arch and, in turn, its historiography.

Published: March 2021

Background and objectives:

Left ventricular assist devices enable recovery from severe heart failure and serve as a bridge to heart transplantation. However, chronic mechanical unloading can impair myocardial recovery. We aimed to assess myocyte size, fibrosis, apoptosis, and β-adrenoreceptor levels after rats with left ventricle unloading induced by heterotopic heart transplantation were administered carvedilol and metoprolol.

Methods:

Thirty rats with heart transplants were divided randomly into control, carvedilol treatment, and metoprolol treatment groups. Follow-up was conducted after 2 and 4 weeks of unloading.

Results:

Carvedilol and metoprolol treatments did not prevent the decrease in myocyte diameter in unloaded left ventricles. Metoprolol significantly decreased the ratio of the fibrotic area in the unloaded heart, measured using Masson’s trichrome staining after 2 weeks. However, carvedilol and metoprolol did not reduce apoptosis, based on measurements of terminal deoxynucleotidyl-transferase-mediated dUTP nick end-labelling positive cells and the expression of caspase-3 in unloaded hearts after 2 and 4 weeks. Metoprolol treatment did not significantly decrease the mRNA expression of myocardial SERCA2a in the unloaded heart after 2 weeks.

Conclusions:

Compared to carvedilol treatment, metoprolol treatment improved myocardial fibrosis and SERCA2a expression to a greater extent; however, neither drug prevented myocardial apoptosis.

Introduction:

Music festivals are popular events often including camping at the festival site. A mix of music, alcohol, drugs, and limited hygiene increases health risks. This study aimed to assess the use of medical supplies at a major music festival, thereby aiding planning at similar events in the future.

Method:

The Medical Health Care Organization (MHCO) at Roskilde Festival 2016 (Denmark) collected prospective data on disposable medical supply use and injuries and illnesses presenting to the MHCO.

Results:

A total of 12,830 patient presentations were registered by the MHCO and a total of 104 different types of disposable medical supplies were used by the MHCO from June 25, 2016 through July 3, 2016. Out of 12,830 cases, 594 individuals (4.6%) had a potential or manifest medical emergency, 6,670 (52.0%) presented with minor injuries, and 5,566 (43.4%) presented with minor illnesses. The overall patient presentation rate (PPR) was 99.0/1,000 attendees and the transport-to-hospital rate (TTHR) was 2.1/1,000 attendees. For medical emergencies, the most frequently used supplies were aluminum rescue blankets (n = 627), non-rebreather masks (n = 121), and suction catheters for an automatic suction unit (ASU) for airway management (n = 83). Most used diagnostic equipment were blood glucose test strips (n = 1,155), electrocardiogram electrodes (n = 960), and urinary test strips (n = 400). The most frequently used personal protection equipment were non-sterile gloves (n = 1,185 pairs) and sterile gloves (n = 189).

Conclusion:

This study demonstrates a substantial use of disposable medical supplies at a major music festival. The results provide aid for planning similar mass-gathering (MG) events.
The effect of motivational interviewing on ambivalence in social anxiety disorder
Authors: Romano Mia , Peters Lorna
Published: March 2021

Background:

One reason that motivational interviewing (MI) is thought to translate well to a variety of treatment domains is due to the focus on client ambivalence.

Aims:

Therefore, the current study aimed to explore the construct of ambivalence in the context of MI and cognitive behavioural therapy (CBT) for social anxiety disorder (SAD).

Method:

Participants were 147 individuals diagnosed with SAD who were randomised to receive either MI or supportive counselling prior to receiving group CBT for SAD.

Results:

The results suggested that MI was not related to decreases in general ambivalence or treatment ambivalence, although an indicator of treatment ambivalence was found to predict worse treatment outcome.

Conclusions:

The findings suggest that three sessions of MI prior to CBT may not decrease ambivalence in participants with SAD, which may underscore the potential importance of tackling ambivalence as it arises during CBT.

Objective:

The current cross-sectional study examined cognition and performance-based functional abilities in a continuing care senior housing community (CCSHC) that is comparable to other CCSHCs in the US with respect to residents’ demographic characteristics.

Method:

Participants were 110 older adult residents of the independent living unit. We assessed sociodemographics, mental health, neurocognitive functioning, and functional capacity.

Results:

Compared to normative samples, participants performed at or above expectations in terms of premorbid functioning, attention span and working memory, processing speed, timed set-shifting, inhibitory control, and confrontation naming. They performed below expectation in verbal fluency and verbal and visual learning and memory, with impairment rates [31.4% (>1 SD below the mean) and 18.49% (>1.5 SD below the mean)] well above the general population (16% and 7%, respectively). Within the cognitive test battery, two tests of delayed memory were most predictive of a global deficit score. Most cognitive test scores correlated with performance-based functional capacity.

Conclusions:

Overall, results suggest that a subset of older adults in the independent living sector of CCSHCs are cognitively and functionally impaired and are at risk for future dementia. Results also argue for the inclusion of memory tests in abbreviated screening batteries in this population. We suggest that CCSHCs implement regular cognitive screening procedures to identify and triage those older adults who could benefit from interventions and, potentially, a transition to a higher level of care.
Emotion Recognition Deficits in the Differential Diagnosis of Amnestic Mild Cognitive Impairment: A Cognitive Marker for the Limbic-Predominant Phenotype

Published: March 2021

Objective:

Late-onset amnestic mild cognitive impairment (aMCI) with long disease course and slow progression has been recently recognized as a possible phenotypical expression of a limbic-predominant neurodegenerative disorder. Basic emotion recognition ability crucially depending on temporo-limbic integrity is supposed to be impaired in this group of MCI subjects presenting a selective vulnerability of medio-temporal and limbic regions. However, no study specifically investigated this issue.

Methods:

Hereby, we enrolled 30 aMCI with a biomarker-based diagnosis of Alzheimer’s disease (i.e., aMCI-AD, n = 16) or a biomarker evidence of selective medio-temporal and limbic degeneration (aMCI-mTLD, n = 14). Ekman-60 Faces Test (Ek-60F) was administered to each subject, comparing the performance with that of 20 healthy controls (HCs).

Results:

aMCI-mTLD subjects showed significantly lower Ek-60F global scores compared to HC (p = 0.001), whose performance was comparable to aMCI-AD. Fear (p = 0.02), surprise (p = 0.005), and anger (p = 0.01) recognition deficits characterized the aMCI-mTLD performance. Fear recognition scores were significantly lower in aMCI-mTLD compared to aMCI-AD (p = 0.04), while no differences were found in other emotions.

Conclusions:

Impaired social cognition, suggested by defective performance in emotion recognition tasks, may be a useful cognitive marker to detect limbic-predominant aMCI subjects among the heterogeneous aMCI population.
Scaling up and zooming in: global history and high-definition archaeology perspectives on the longue durée of urban–environmental relations in Gerasa (Jerash, Jordan)

Published: March 2021

Combining global perspectives with localized case studies and integrating scientific and material evidence of environmental change in historical narratives are amongst the main challenges for the field of global history in addressing the dawn of the Anthropocene. In this article, we trace the relationship of the city of Gerasa (Jerash, Jordan) with its riverine hinterland, from the first millennium BCE until the nineteenth century CE. We argue that the study of long-term historical trajectories of microregions not only depends on context from regional and global history timelines, but also has the potential to provide insights relevant to those scales in return. Zooming in and scaling up must go hand in hand in order for global history perspectives to be properly informed, and archaeology and natural sciences have crucial insights to offer – although importantly only when evidence comes from well-contextualized frameworks.
Let's do it Frank's way: general principles and historical specificity in the study of entrepreneurship
Authors: Hudik Marek , Bylund Per L.
Published: March 2021

Formal economic models of entrepreneurship have two characteristics: they model entrepreneurship as an allocation of resources, and they identify common factors affecting this allocation. These common factors are represented as parameters of optimization models, and they are evaluated at the market level. We argue that although these models are useful, they are incomplete because certain aspects of entrepreneurial behavior, such as judgment, alertness, or innovativeness, cannot be easily transformed into allocative problems. Moreover, entrepreneurial acts involve idiosyncratic elements, which limit the applicability of the market-level analysis to individual cases. Thus, the traditional economic methods have to be complemented by approaches highlighting the role of individual and historical specificity. The study of entrepreneurship, therefore, requires a synthesis of both general theory and historicist approaches, as envisioned a century ago by Frank Knight.

Previous research has shown that individuals suffering from depression and generalized anxiety disorder (GAD) seem to have inhibitory control deficits compared with healthy controls. However, few studies have been conducted in Spanish-speaking countries. Thus, this study aims to analyze the performance on the Stroop Color and Word Test (SCWT) between groups of Colombian participants with clinical levels of depression and GAD symptoms and a nonclinical control group. According to previous research, we expected to find significant differences in inhibitory control among groups. An ex post facto design was implemented. The SCWT was administered to a total sample of 105 individuals (64.8% women, M = 22.94 years, SD = 4.62), including 27 depressed and 15 anxious participants according to their scores on the Personal Health Questionnaire–9 and the Generalized Anxiety Disorder–7, respectively. Bayesian t-tests showed that depressed participants showed the same processing speed but lower scores on inhibitory control than healthy controls, BF = 13.70, δ = 0.50, 95% CI [0.08, 0.94]. Conversely, anxious participants showed deficits in processing speed, SCWT-Word: BF = 16.19, δ = 0.68, 95% CI [0.15, 1.24]; SCWT-Color: BF = 5.98, δ = 0.50, 95% CI [–0.01, 1.04], but not in inhibitory control compared with the nonanxious counterparts. This study provides preliminary evidence concerning the inhibitory control deficits in Colombian depressed individuals and processing speed deficits in those experiencing clinical levels of GAD symptoms.
