Authors: Kim Jieun , Hwang Dong-Uk , Son Edwin J. , Oh Sang Hoon , Kim Whansun , Kim Youngkyung , Kwon Gusang
Published: November 2022

We report a deep learning-based emotion recognition method using EEG data collected while applying cosmetic creams. Four creams with different textures were randomly applied, and they were divided into two classes, “like (positive)” and “dislike (negative)”, according to the preference score given by the subject. We extracted frequency features using well-known frequency bands, i.e., alpha, beta and low and high gamma bands, and then we created a matrix including frequency and spatial information of the EEG data. We developed seven CNN-based models: (1) inception-like CNN with four-band merged input, (2) stacked CNN with four-band merged input, (3) stacked CNN with four-band parallel input, and stacked CNN with single-band input of (4) alpha, (5) beta, (6) low gamma, and (7) high gamma. The models were evaluated by the Leave-One-Subject-Out Cross-Validation method. In like/dislike two-class classification, the average accuracies of all subjects were 73.2%, 75.4%, 73.9%, 68.8%, 68.0%, 70.7%, and 69.7%, respectively. We found that the classification performance is higher when using multi-band features than when using single-band feature. This is the first study to apply a CNN-based deep learning method based on EEG data to evaluate preference for cosmetic creams.
Survival status and predictors of mortality among low-birthweight neonates admitted to KMC units of five public hospitals in Ethiopia: Frailty survival regression model
Authors: Debere Mesfin Kote , Haile Mariam Damen , Ali Ahmed , Mekasha Amha , Chan Grace J.
Published: November 2022

Background

Low birth weight (LBW) and preterm birth are leading causes of under-five and neonatal mortality globally. Data about the timing of death and outcomes for LBW and preterm births are limited in Ethiopia and could be used to strengthen neonatal healthcare. This study describes the incidence of neonatal mortality rates (NMR) stratified by newborn size at birth for gestational age and identifies its predictors at five public hospitals in Ethiopia.

Methods

A prospective follow-up study enrolled 808 LBW neonates from March 2017 to February 2019. Sex-specific birthweight for gestational age percentile was constructed using Intergrowth 21stcharts. Mortality patterns by birthweight for-gestational-age-specific survival curves were compared using the log-rank test and Kaplan-Meier survival curves. A random-effects frailty survival model was employed to identify predictors of time to death.

Results

Among the 808 newborns, the birthweight distribution was 3.2% <1000 g, 28.3% <1500 g, and 68.1% <2000 g, respectively. Birthweight for gestational age categories were 40.0% both preterm and small for gestational age (SGA), 20.4% term SGA, 35.4% appropriate weight for gestational age, and 4.2% large for gestational age (LGA). The sample included 242 deaths, of which 47.5% were both preterm and SGA. The incidence rate of mortality was 16.17/1000 (95% CI 14.26–18.34) neonatal-days of observation.

Neonatal characteristics independently related to increased risk of time-to-death were male sex (adjusted hazards ratio [AHR] 3.21 95% CI 1.33–7.76), born preterm (AHR 8.56 95% CI 1.59–46.14), having been diagnosed with a complication (AHR 4.68 95% CI 1.49–14.76); some maternal characteristics and newborn care practices (like lack of effective KMC, AHR 3.54 95% CI 1.14–11.02) were also significantly associated with time-to-death.

Conclusions

High mortality rates were measured for low birthweight neonates–especially those both preterm and SGA births–even in the context of tertiary care. These findings highlight the need for improved quality of neonatal care, especially for the smallest newborns.
Plasma parathyroid hormone response to vitamin D3 supplementation among women of reproductive age: A randomized double-blind placebo-control trial
Authors: Zan Megan Chong Hueh , Ying Melissa Leong En , Cheong Loke Seng , Lin Khor Geok
Published: November 2022

While vitamin D inadequacy occurs worldwide, there is a lack of consensus internationally on the optimum plasma levels of 25(OH)D to maximally suppress the level of parathyroid hormone toward reducing bone loss. This study aimed to investigate the response of intact parathyroid hormone (iPTH) to vitamin D3 supplementation among Malaysian women of reproductive age in a randomised double-blind placebo-control trial [NMRR-15-479-25680]. A total of 106 women who fulfilled the study inclusion criteria were randomly assigned to receive daily one of these three supplement doses (i) 600 IU vitamin D3 + 500 mg calcium; (ii) 1200 IU vitamin D3 + 500 mg calcium; or (iii) 4000 IU vitamin D3 + 500 mg calcium. The placebo group received daily 500 mg calcium. The outcome examined was change in plasma iPTH concentration in response to daily vitamin D3 supplementation for 16 weeks. Fasting blood sample was obtained at baseline and post-supplementation. A total of 78 subjects (73.6%) completed the intervention. None of the supplementation groups brought about any detectable suppression of iPTH concentration post-supplementation. Vitamin D3 supplementation resulted in overall increase in plasma 25(OH)D levels, but only the 4000 IU/day group showed a significant dose effect post-supplementation (mean 49.7 ± 26.5 nmol/L) compared to placebo (29.3 ± 13.3 nmol/L). The lack of iPTH suppression is attributed to high prevalence of vitamin D insufficiency at baseline and the supplementation regimen was inadequate to raise the 25(OH)D level to cause PTH suppression. Inadequate calcium intake of the participants was also a likely contributing factor to the result. As prolonged vitamin D insufficiency and hypocalcaemia could lead to a compensatory rise in PTH resulting in accelerated bone loss, as well as posing increasing risks of non-skeletal morbidities, further clinical trials with an adequately powered sample size should be undertaken over an appropriate study duration to verify the results obtained in this study.
What do people write about COVID-19 and teaching, publicly? Insulators and threats to newly habituated and institutionalized practices for instruction
Authors: Martinez Mario Antonio
Published: November 2022

Covid represents major changes in teaching across the world. This study examined some of those changes through tweets that contained threats and insulators to habitualization of newer teaching practices. The investigator harvested tweets to determine sentiment differences between teaching and schools and teaching and online. Topic modeling explored the topics in two separate corpora. Omnibus Yuen’s robust bootstrapped t-tests tested for sentiment differences between the two corpora based on emotions such as fear, anger, disgust, etc. Qualitative responses voiced ideas of insulation and threats to teaching modalities institutionalized during the pandemic. The investigator found that ‘teaching and school’ was associated with higher anger, distrust, and negative emotions than ‘teaching and online’ corpus sets. Qualitative responses indicated support for online instruction, albeit complicated by topic modeling concerns with the modality. Some twitter responses criticized government actions as restrictive. The investigator concluded that insulation and threats towards habitualization and institutionalization of newer teaching modalities during covid are rich and sometimes at odds with each other, showing tension at times.
Modelling the health and economic impact of sugary sweetened beverage tax in Canada
Authors: Liu Siyuan , Veugelers Paul J. , Maximova Katerina , Ohinmaa Arto
Published: November 2022

Background

With the increasing concerns about the health and economic burden attributed to sugar-sweetened beverages (SSBs) consumption, SSB taxation has been proposed and implemented in many countries. Many previous economic evaluations of SSB taxation have shown that this kind of policy is cost-effective. However, the magnitude of impact varies. This study aims to design a comprehensive model to estimate the impact and cost-effectiveness of the SSB tax in Canada.

Methods

A proportional multi-state life table-based Markov model was chosen to estimate the impacts of SSB tax in Canada. The health-related quality of life (including disability-adjusted life years (DALYs) and quality-adjusted life years (QALYs)), the costs (including health care costs and intervention costs), and the tax revenue were the main health and economic outcomes. We compared the simulated SSB tax with the current practice from the public health care payer perspective, and the tax was applied to the 2015 adult Canadian population up to 100 years. The economic model was built following guidelines from the Canadian Agency for Drugs and Technologies in Health.

Results

After implementing a CAD$0.015/oz SSB tax, 282,104 cases of overweight and obesity, 210,542 cases of diseases, and 2,189 deaths could be prevented. The simulated SSB tax has the potential to avert 2.3 million DALYs, gain 1.5 million QALYs, and save CAD$32,583 million in health care costs in a lifetime period. The incremental cost-effectiveness ratio for the SSB tax was CAD$ -24,933/QALY. The SSB tax with different tax levels (CAD$0.01/oz and CAD$0.02/oz) remained cost-effective.

Conclusion

Implementing the SSB tax in Canada is a potential cost-effective policy option for reducing obesity and related chronic diseases. The model built in this study provides a more accurate estimate of health and economic impact of SSB tax and could be used to estimate other sugar tax options.
Relationship between early-career collaboration among researchers and future funding success in Japanese academia
Authors: Tsugawa Sho , Kanetsuki Takuya , Sugihara Junichi
Published: November 2022

Academia is becoming more and more competitive, especially for young scientists, so it is important to understand the factors that affect success in academic careers. To survive in academia, it is crucial to obtain research funding. Previous studies have investigated factors that affect the funding success of researchers. In this paper, we focus on research collaboration structure as a factor affecting funding success. More specifically, we investigate the effects of participation in joint research projects, number of joint research projects, and centrality in the collaborative network on the future funding success of junior researchers in Japan. Our results show that participation in joint research projects and the number of such projects significantly affect the future funding success of junior researchers. Furthermore, the median number of years of funding received by researchers involved in joint research projects was found to be about 1.5 times greater than that of researchers not involved in joint research projects, and the average amount of research funding received after 10 years is about 2–4 times more, suggesting that researchers with collaboration ties with other researchers in the early stages of their career tend to be more successful in the future.
Mediators and the vitality of matter in drawing practices
Authors: Mellor Jemma Naomi
Published: November 2022

Materials are a vital collaborator in building human and non-human worlds and yet are often cast as simply assistants or props in art practice. This project report looks at an experimental drawing exercise, which gives non-traditional drawing materials a crucial position in the drawing and mark-making discipline. This exercise is part of a larger methodology that seeks to give materiality a more central role in wider arts practice in order to bring individual material or object into a closer working relationship with the artist. Through such practices we can learn more about our material collaborates, from how matter reveals itself when used as a mark marker to how tacit and sensorial knowledge can be developed between material and artist. The drawing exercise, which is explored in this report, utilizes alternatives to the traditional tools of drawing practices (e.g. pens, pencils or brushes) to explore how material can be used as both illustrator and illustrated to develop a deeper relational knowledge of the materials which surround us. In recent theoretical, political and technological fields, through movements such as New Materialism, the role of materials in research is being re-examined and this report applies this call for a more collaborative relationship with the material world specifically to art and design pedagogies. This approach has the potential to transform our knowledge of specific materials through personal sensorial experience and an acknowledgement of material’s own vitality, and I have already witnessed something of the realization of this in my own practice.
Three Turns: A dialogue across disciplines
Authors: Munnelly Lisa
Published: November 2022

On 21 February 2021 at 9.00 p.m., the performance Three Turns was featured as part of a curated series of works in The Performance Arcade (PA2021), a festival that brought together live art, music and performance on Wellington’s Waterfront. In a shipping container transformed into a temporary stage, three artists: a drawer, a dancer and a musician, celebrated the immediacy of their mediums. In an hour-long performance, a dialogue across disciplines was formed, a dialogue that evolved intuitively. Over three turns, each artist took the lead, with a note, a mark and a gesture offered up as provocation – forms, actions, colours and chords followed. The sonic surface, the stage and the page merged into a single space in which the artists explored velocity, rhythm and repetition. This encounter created a place where gravity and levity pushed and pulled, space was devoured and patterns emerged, accumulated and dissipated. The collaborative performance of Three Turns allowed three artists to form a dialogue across disciplines and ask: what new knowledge can emerge from a conversation between drawing, dance and music? This report, written in the first person from the drawer’s perspective, with contributions from The Dancer/Sacha Copland and The Musician/Simon Eastwood, reflects upon the event and posits that whilst on an individual level the performance produced new drawings, new sounds and new movements that individually had value, it was the relation between the three artists and their mediums, that emerged to be the most significant aspect of the work.

Inguruneko ezaugarriek eragina izan dezakete herritarron portaera osasungarrietan. Badirudi bizi garen tokiaren eta gure elikadura-ohituren artean erlazioa dagoela. Beraz, ingurunea bizilagunen ikuspegitik ezagutzea beharrezkoa da biztanleriaren elikaduran eragina duten determinatzaileak baloratzeko. Ikerketa gutxik aztertu dituzte hiri-inguruneak herritarren ikuspuntutik. Horregatik, azterlan honen helburua Bilboko auzo bateko elikadura-ingurunearen diagnostiko komunitarioa egitea izan zen, eta horretarako Photovoice Partaidetza-Ekintza Ikerketa metodologia erabili zen. Proiektu honetarako parte-hartzaileak Auzo Elkarteen bidez bildu ziren. Photovoice-rako, inklusio-irizpideak betetzen zituzten gizon eta emakumeez osaturiko talde heterogeneoa sortu zen. 2017ko apiriletik uztailera, aukeratutako 6 auzotarrek bi orduko iraupeneko 5 talde-saiotan parte hartu zuten, eta haiek ateratako argazkiei buruzko eztabaida kritikoak egin ziren. Auzoko elikadura-ingurunea deskribatzeko 30 argazki batu ziren guztira. Adostasun-prozesu baten ondoren, parte-hartzaileek 9 kategoria identifikatu zituzten eta horiei lotutako 13 argazki adierazgarri aukeratu zituzten. Amaitzeko, emaitza horietan nabarmendutako ezaugarriak 6 gai kontzeptualetan batu ziren: 1) Ohitura txarrak, 2) Kultura-aniztasuna, 3) Harreman sozialak, 4) Iraunkortasuna, 5) Merkataritzaren eraldaketa, 6) Ohitura osasungarriak. Herritarrek beren elikadura-ingurunea hobetzeko proposatutako gomendioak Bilboko arduradun politikoei aurkeztu zitzaizkien. Photovoice proiektuaren bitartez herritarrek beren elikadura-inguruneari buruz zuten ikuspegia ezagutu zen. Auzotarren eskutik lortutako ondorioak lagungarriak izan daitezke tokian tokiko politika eta esku-hartzeak gidatzeko, elikadura-ingurune osasungarriagoak sustatzeko helburuarekin.
Gizakiaren aurpegiaren ezaugarri fenotipikoei loturiko aldakortasun genetikoaren analisia
Authors: Cabrejas Amaia , Alonso Santos , Izagirre Neskuts
Published: November 2022

Aurpegiaren morfologia ezinbestekoa da banakoak euren artean ezberdindu ahal izateko. Lan honetan, aurpegiko ezaugarrietan eragina duten SNPak aztertu ditugu. Populazioen historia demografikoak aurpegiaren morfologiaren aldakortasunaren proportzio handia azaltzen duela aurkitzen dugu. Hala ere, aurpegiaren aldakortasunean hautespen sexuala bezalako beste faktore batzuek ere eragina izan dezakete, nahiz eta maila txikiagoan. Sudurraren morfologian arreta jarriz, Asia ekialdeko eta Afrikako populazioek sudur zabalagoa dute oro har, eta europarrek estuagoa. Bestalde, aurpegiaren ezaugarriei loturiko SNPen azterketa auzitegi-zientzietan ere erabilgarria izan daiteke, nahiz eta gaur egun DNAtik abiatuta banako baten identifikazio fenotipikoa konplexua den. Lan honen helburua da giza populazioak aurpegiaren morfologiari loturiko datu genetikoetatik (SNPak) abiatuta desberdintzea posible den egiaztatzea.
Há vila além da Costa. Urbanidade(s) em Cabo Verde no século XIX
Authors: Pires Fernando
Published: November 2022

É dado adquirido que os principais núcleos urbanos em Cabo Verde formaram-se e desenvolveram-se em torno de um porto de mar. Considerando que se trata de ilhas, que dependem do mar para comunicação e comércio, tal afirmação não parece ser contestável. Contudo, e sem negar a imprescindível relação com o mar, a urbanização das ilhas não ocorre apenas na costa. Fruto de um longo processo de ruralização, outros núcleos de povoamento despontaram no interior de outras ilhas. São povoações de base agrária, que já no século XVIII pareceram suficientemente populosas para receberem o título de vilas e que ao longo do século XIX se pretendem afirmar como tais. Este livro discute o processo de afirmação e de criação de novas vilas em Cabo Verde no século XIX apresentando os casos da Vila da Ribeira Brava, na ilha de São Nicolau, da Vila da Ribeira Grande, na ilha de Santo Antão e da Vila Nova Sintra, na ilha Brava. Cada um destes exemplos problematiza de maneira específica algumas das vicissitudes dos processos de transformação urbana no arquipélago. Estes retomam métodos e formas longamente utilizados no urbanismo português, onde a persistência dos resultados é significativa e para os quais os exemplos de Cabo Verde trazem dados relevantes, que não são tão discretos quanto parecem.

Background and Aim: Indonesia's farming practices are a perfect setting for establishing an infection with Fasciola gigantica which can result in economically detrimental. The objectives of the current study were to describe and analyze the transmission dynamics of fasciolosis (F. gigantica) in Prafi District, to provide information on effective control strategies and to identify risk factors associated with fasciolosis in cattle.

Materials and Methods: Fecal samples were purposively collected from the rectum of 60 beef cattle in Prafi District, Manokwari Regency, West Papua Province, Indonesia. The samples were collected once a month for 8 months from April 2019 to November 2019. Furthermore, the samples were taken from two rearing system groups: 30 stall cattle and 30 cattle in a palm oil garden. The presence of F. gigantica eggs in the fecal samples was examined using a modified Danish Bilharziasis Laboratory technique-sedimentation. Meanwhile, the antigenic diagnosis of Fasciola in the fecal samples was analyzed using an enzyme-linked immunosorbent assay kit to perform an indirect sandwich assay on feces. Snails were collected from an irrigation canal, rice field, and palm oil garden canal around Prafi District. These snails were examined for infection with cercariae larvae of F. gigantica by cercarial shedding and crushing techniques.

Results: The peak occurrence of F. gigantica infection was identified in August (65.00%) and the lowest in June (35.00%). The highest prevalence of fasciolosis in cattle was recorded in August and November (90.00%) and the lowest was in May (40.00%). Moreover, the highest prevalence of fasciolosis in cattle exposed to the palm oil garden was recorded in April (53.33%) and the lowest prevalence of F. gigantica infection was recorded in June (23.33%). In total, 2046 snails were screened by the cercarial shedding and crushing method; of these, 426 (20.82%) were found to be positive for trematode cercariae. The prevalence of F. gigantica infection in Lymnaea spp. snails was highest in November (47.46%) and lowest in April (9.28%).

Conclusion: The current study shows that beef cattle grown in two types of rearing systems in Prafi District were infected with F. gigantica during the dry and rainy season. It was revealed that Lymnaea spp. are common snails found in and around Prafi District, and can act as intermediate hosts with an infective stage of trematode. The transmission to cattle was highly effective, despite the short activity period, the low infection rate of snails, and the incidental anthelminthic treatment.
Family Court in England and Wales: An Effective Safety Net?
Authors: Mant Jessica
Published: November 2022

This article contributes an insight into how the decline of legal aid in family law has transformed the role of the family court in England and Wales, and how this is, in turn, is affecting the sustainability of the family justice system as a whole. It will begin by setting out some of the pressures that have historically characterized the legal aid system in England and Wales, focusing specifically on how family law advice and representation has been uniquely and particularly targeted by a host of intersecting political efforts to minimize people’s use of family lawyers and the family court when their relationships break down. The article will then turn to consider the consequences of this for the family court. Here, the article will reflect upon how these pressures have constrained capacity and altered working practices within the family court. In sum, it will examine how the decline of legal aid has impaired the extent to which the family court can effectively operate as a safety net for families in crisis, and what the future may hold for family justice.

Keywords: legal aid; access to justice; family law; litigants in person.
Beyond Advice Deserts: Strategic Ignorance and the Lack of Access to Asylum Legal Advice
Authors: Wilding Jo
Published: November 2022

This essay explores the role of strategic ignorance in relation to access to legal advice in England and Wales, drawing on the work of Linsey McGoey (2012; 2019; 2020), taking areas of extreme shortage of immigration and asylum legal advice as an example of the wider phenomenon in access to justice. It argues that there is a misplaced belief in market-based procurement to meet advice needs, which leads to a failure to collect evidence to understand whether the market does in fact achieve this. This avoidance of evidence about market functioning and the relationship between demand and provision is facilitated by fragmentation of both policy and operational responsibilities, leaving large gaps for ignorance, in which the accounts and concerns of advice-users are dismissed as not credible. It argues that, in failing to collect adequate evidence about the functioning of the market, the Lord Chancellor is ignoring a statutory duty to secure the availability of legal aid.

Keywords: legal aid; advice deserts; strategic ignorance; asylum and immigration; LASPO Act 2012 section 2.
Sleep-Facilitated Sexual Assault
Authors: Rumney Philip N S , McPhee Duncan
Published: November 2022

This note addresses a form of rape that is neglected in the scholarly literature. This form of offending occurs when a male uses his penis to vaginally, orally or anally penetrate a female or male who is sleeping at the time of the penetration. The data on which this note is based is gathered from a total sample of 441 police rape investigation case files, from which 39 of these sleep cases are identified. The note examines some of the characteristics of these cases, investigative trajectories through the criminal justice process and the behaviour of suspects. Given the neglect with which this issue has been treated, it is argued that further research would be beneficial so as to improve our understanding of the rape of those who are sleeping and the criminal justice and police response to this problem.

Keywords: rape; victims; suspects; sleep; police investigations.
