Published: June 2021

The goal is to examine the risk of conception mode-type-1 diabetes using different survival analysis modelling approaches and examine if there are differentials in the risk of type-1 diabetes between children from fresh and frozen-thawed embryo transfers. We aimed to compare the performances and fitness of different survival analysis regression models with the Cox proportional hazard (CPH) model used in an earlier study. The effect of conception modes and other prognostic factors on type-1 diabetes among children conceived either spontaneously or by assisted reproductive technology (ART) and its sub-groups was modelled in the earlier study. We used the information on all singleton children from the Swedish Medical Birth Register hosted by the Swedish National Board of Health and Welfare, 1985 to 2015. The main explanatory variable was the mode of conception. We applied the CPH, parametric and flexible parametric survival regression (FPSR) models to the data at 5% significance level. Loglikelihood, Akaike and Bayesian information criteria were used to assess model fit. Among the 3,138,540 singletons, 47,938 (1.5%) were conceived through ART (11,211 frozen-thawed transfer and 36,727 fresh embryo transfer). In total, 18,118 (0.58%) of the children had type-1 diabetes, higher among (0.58%) those conceived spontaneously than the ART-conceived (0.42%). The median (Interquartile range (IQR)) age at onset of type-1 diabetes among spontaneously conceived children was 10 (14–6) years, 8(5–12) for ART, 6 (4–10) years for frozen-thawed embryo transfer and 9 (5–12) years for fresh embryo transfer. The estimates from the CPH, FPSR and parametric PH models are similar. There was no significant difference in the risk of type-1 diabetes among ART- and spontaneously conceived children; FPSR: (adjusted Hazard Ratio (aHR) = 1.070; 95% Confidence Interval (CI):0.929–1.232, p = 0.346) vs CPH: (aHR = 1.068; 95%CI: 0.927–1.230, p = 0.361). A sub-analysis showed that the adjusted hazard of type-1 diabetes was 37% (aHR = 1.368; 95%CI: 1.013–1.847, p = 0.041) higher among children from frozen-thawed embryo transfer than among children from spontaneous conception. The hazard of type-1 diabetes was higher among children whose mothers do not smoke (aHR = 1.296; 95%CI:1.240–1.354, p<0.001) and of diabetic mothers (aHR = 6.419; 95%CI:5.852–7.041, p<0.001) and fathers (aHR = 8.808; 95%CI:8.221–9.437, p<0.001). The estimates from the CPH, parametric models and the FPSR model were close. This is an indication that the models performed similarly and any of them can be used to model the data. We couldn’t establish that ART increases the risk of type-1 diabetes except when it is subdivided into its two subtypes. There is evidence of a greater risk of type-1 diabetes when conception is through frozen-thawed transfer.

Based on several lines of evidence, numerous investigators have suggested that acetaminophen exposure during early development can induce neurological disorders. We had previously postulated that acetaminophen exposure early in life, if combined with antioxidants that prevent accumulation of NAPQI, the toxic metabolite of acetaminophen, might be innocuous. In this study, we administered acetaminophen at or below the currently recommended therapeutic dose to male laboratory rat pups aged 4–10 days. The antioxidants cysteine and mannitol were included to prevent accumulation of NAPQI. In addition, animals were exposed to a cassette of common stress factors: an inflammatory diet, psychological stress, antibiotics, and mock infections using killed bacteria. At age 37–49 days, observation during introduction to a novel conspecific revealed increased rearing behavior, an asocial activity, in animals treated with acetaminophen plus antioxidants, regardless of their exposure to oxidative stress factors (2-way ANOVA; P < 0.0001). This observation would suggest that the initial hypothesis is incorrect, and that oxidative stress mediators do not entirely eliminate the effects of acetaminophen on neurodevelopment. This study provides additional cause for caution when considering the use of acetaminophen in the pediatric population, and provides evidence that the effects of acetaminophen on neurodevelopment need to be considered both in the presence and in the absence of oxidative stress.
Being mindful in the tax context in Italy: Examining whether and how mindfulness relates with tax evasion intentions and support for tax progressivity
Authors: De Cristofaro Valeria , Giacomantonio Mauro , Pellegrini Valerio , Salvati Marco , Leone Luigi
Published: June 2021

Two studies explored whether and how mindfulness relates with citizens’ tax evasion intentions and support for progressive tax rates. Based on theoretical and empirical grounds, in Study 1 (N= 1,175) we proposed that mindfulness would be negatively related with tax evasion intentions through decreased social dominance orientation. Drawing on Duckitt’s dual-process motivational model, in Study 2 (N= 722) we proposed that mindfulness would be positively related with support for progressive taxation through the mediation of lower competitive-jungle beliefs, and then lower social dominance orientation. Instead, we did not expect to find mediation of the link between mindfulness and support for progressive taxation through dangerous-world beliefs and right-wing authoritarianism. These studies inform about the motivational pathways through which mindfulness relates with tax evasion intentions and support for progressive taxation.

Published: June 2021

A living-donor kidney transplant (LDKT) is one of the best treatments for kidney failure. The UK’s LDKT activity falls behind that of many other countries, and there is evidence of socioeconomic inequity in access. We aimed to develop a UK-specific multicomponent intervention to support eligible individuals to access a LDKT. The intervention was designed to support those who are socioeconomically-deprived and currently disadvantaged, by targeting mediators of inequity identified in earlier work. We identified three existing interventions in the literature which target these mediators: a) the Norway model (healthcare practitioners contact patients’ family with information about kidney donation), b) a home education model, and c) a Transplant candidate advocate model. We undertook intervention development using the Person-Based Approach (PBA). We performed in-depth qualitative interviews with people with advanced kidney disease (n = 13), their family members (n = 4), and renal and transplant healthcare practitioners (n = 15), analysed using thematic analysis. We investigated participant views on each proposed intervention component. We drafted intervention resources and revised these in light of comments from qualitative ‘think-aloud’ interviews. Four general themes were identified: i) Perceived cultural and societal norms; ii) Influence of family on decision-making; iii) Resource limitation, and iv) Evidence of effectiveness. For each intervention discussed, we identified three themes: for the Norway model: i) Overcoming communication barriers and assumptions; ii) Request from an official third party, and iii) Risk of coercion; for the home education model: i) Intragroup dynamics; ii) Avoidance of hospital, and iii) Burdens on participants; and for the transplant candidate advocates model: i) Vested interest of advocates; ii) Time commitment, and iii) Risk of misinformation. We used these results to develop a multicomponent intervention which comprises components from existing interventions that have been adapted to increase acceptability and engagement in a UK population. This will be evaluated in a future randomised controlled trial.
Restrictive versus liberal fluid resuscitation strategy, influence on blood loss and hemostatic parameters in mild obstetric hemorrhage: An open-label randomized controlled trial. (REFILL study)

Published: June 2021

Background

Evidence for optimal hemostatic resuscitation in postpartum hemorrhage (PPH) is lacking. Liberal fluid administration may result in acidosis, hypothermia and coagulopathy.

Objective

We hypothesize that in early PPH a restrictive fluid administration results in less progression to moderate PPH.

Study design

In four Dutch hospitals we recruited women of 18 years and over, and more than 24 weeks pregnant. Exclusion criteria were: anticoagulant therapy, known coagulation disorders, pre-eclampsia, antenatal diagnosis of abnormally adhesive placenta, and a contraindication for liberal fluid therapy. We blindly randomized participants at 500 mL and ongoing blood loss in the third stage of labor between restrictive fluid administration (clear fluids 0.75–1.0 times the volume of blood lost) and liberal fluid administration (clear fluids 1.5–2.0 times the volume of blood lost). The primary outcome was progression to more than 1000 mL blood loss. Analyses were according to the intention-to-treat principle.

Results

From August 2014 till September 2019, 5190 women were informed of whom 1622 agreed to participate. A total of 252 women were randomized of which 130 were assigned to the restrictive group and 122 to the liberal group. In the restrictive management group 51 of the 130 patients (39.2%) progressed to more than 1000 mL blood loss versus 61 of the 119 patients (51.3%) in the liberal management group (difference, -12.0% [95%-CI -24.3% to 0.3%], p = 0.057). There was no difference in the need for blood transfusion, coagulation parameters, or in adverse events between the groups.

Conclusions

Although a restrictive fluid resuscitation in women with mild PPH could not been proven to be superior, it does not increase the need for blood transfusion, alter coagulation parameters, or cause a rise in adverse events. It can be considered as an alternative treatment option to liberal fluid resuscitation.

Published: June 2021

Background

COVID-19’s pulmonary manifestations are broad, ranging from pneumonia with no supplemental oxygen requirements to acute respiratory distress syndrome (ARDS) with acute respiratory failure (ARF). In response, new oxygenation strategies and therapeutics have been developed, but their large-scale effects on outcomes in severe COVID-19 patients remain unknown. Therefore, we aimed to examine the trends in mortality, mechanical ventilation, and cost over the first six months of the pandemic for adult COVID-19 patients in the US who developed ARDS or ARF.

Methods and findings

The Vizient Clinical Data Base, a national database comprised of administrative, clinical, and financial data from academic medical centers, was queried for patients ≥ 18-years-old with COVID-19 and either ARDS or ARF admitted between 3/2020-8/2020. Demographics, mechanical ventilation, length of stay, total cost, mortality, and discharge status were collected. Mann-Kendall tests were used to assess for significant monotonic trends in total cost, mechanical ventilation, and mortality over time. Chi-square tests were used to compare mortality rates between March-May and June-August.

110,223 adult patients with COVID-19 ARDS or ARF were identified. Mean length of stay was 12.1±13.3 days and mean total cost was $35,991±32,496. Mechanical ventilation rates were 34.1% and in-hospital mortality was 22.5%. Mean cost trended downward over time (p = 0.02) from $55,275 (March) to $18,211 (August). Mechanical ventilation rates trended down (p<0.01) from 53.8% (March) to 20.3% (August). Overall mortality rates also decreased (p<0.01) from 28.4% (March) to 13.7% (August). Mortality rates in mechanically ventilated patients were similar over time (p = 0.45), but mortality in patients not requiring mechanical ventilation decreased from March-May compared to June-July (13.5% vs 4.6%, p<0.01).

Conclusions

This study describes the outcomes of a large cohort with COVID-19 ARDS or ARF and the subsequent decrease in cost, mechanical ventilation, and mortality over the first 6 months of the pandemic in the US.
Is personality linked to season of birth?
Authors: Lee Hoseon , Lee Hye-Kyung , Lee Kounseok
Published: June 2021

The environment is a very significant factor in early childhood development. Season of birth (SOB) is a proxy viable for the environment to which the babies are exposed, thus also significant in early development. This study investigates the association between SOB and personality. A total 2,962 college students were included as study participants. The participants were classified into four seasonal groups based on their birth month and underwent a personality assessment using the Temperament and Character Inventory (TCI). Statistical analysis was performed using one-way analysis of variance (ANOVA) and multinomial logistic regression analysis. The male participants born in autumn scored high on the Disorderliness (NS4) subscale (β = 0.055,P= 0.042) and the male participants born in summer and winter scored high on the Extravagance (NS3) subscale (summer: β = 0.072,P= 0.01, winter: β = 0.078,P= 0.003). The difference observed indicates a relationship between the SOB and temperament, especially NS. Our findings suggest that environmental factors may affect temperament in early development, although further research is likely needed to clarify the causality between them.
Directed closure coefficient and its patterns
Authors: Jia Mingshan , Gabrys Bogdan , Musial Katarzyna
Published: June 2021

The triangle structure, being a fundamental and significant element, underlies many theories and techniques in studying complex networks. The formation of triangles is typically measured by the clustering coefficient, in which the focal node is the centre-node in an open triad. In contrast, the recently proposed closure coefficient measures triangle formation from an end-node perspective and has been proven to be a useful feature in network analysis. Here, we extend it by proposing the directed closure coefficient that measures the formation of directed triangles. By distinguishing the direction of the closing edge in building triangles, we further introduce the source closure coefficient and the target closure coefficient. Then, by categorising particular types of directed triangles (e.g., head-of-path), we propose four closure patterns. Through multiple experiments on 24 directed networks from six domains, we demonstrate that at network-level, the four closure patterns are distinctive features in classifying network types, while at node-level, adding the source and target closure coefficients leads to significant improvement in link prediction task in most types of directed networks.
Highly-potent, synthetic APOBEC3s restrict HIV-1 through deamination-independent mechanisms
Authors: McDonnell Mollie M. , Karvonen Suzanne C. , Gaba Amit , Flath Ben , Chelico Linda , Emerman Michael
Published: June 2021

The APOBEC3 (A3) genes encode cytidine deaminase proteins with potent antiviral and anti-retroelement activity. This locus is characterized by duplication, recombination, and deletion events that gave rise to the seven A3s found in primates. These include three single deaminase domain A3s (A3A, A3C, and A3H) and four double deaminase domain A3s (A3B, A3D, A3F, and A3G). The most potent of the A3 proteins against HIV-1 is A3G. However, it is not clear if double deaminase domain A3s have a generalized functional advantage to restrict HIV-1. In order to test whether superior restriction factors could be created by genetically linking single A3 domains into synthetic double domains, we linked A3C and A3H single domains in novel combinations. We found that A3C/A3H double domains acquired enhanced antiviral activity that is at least as potent, if not better than, A3G. Although these synthetic double domain A3s package into budding virions more efficiently than their respective single domains, this does not fully explain their gain of antiviral potency. The antiviral activity is conferred both by cytidine-deaminase dependent and independent mechanisms, with the latter correlating to an increase in RNA binding affinity. T cell lines expressing this A3C-A3H super restriction factor are able to control replicating HIV-1ΔVif infection to similar levels as A3G. Together, these data show that novel combinations of A3 domains are capable of gaining potent antiviral activity to levels similar to the most potent genome-encoded A3s, via a primarily non-catalytic mechanism.

Published: June 2021

This research was conducted through two studies, the purposes of the first study were to assess tension and self-awareness levels among the tenth-grade male and female students in Qalqilia city in Palestine, and to examine the impact of gender on tension and self-awareness. To achieve these goals a descriptive method was used, the sample consisted of (158) male and (152) female students age 16 years old. They were stratified randomly selected. This study found tension appears to be a broad problem in Palestine among respondents, and it is chronically existent with a high level. On the other hand, this study proved that self-awareness among Palestinian adolescents is low. No significant differences in tension and self-awareness due to gender were found. The objective of study 2 was, to examine the effect of psychodrama on the levels of tension and self-awareness of tenth-grade male students in Qalqilia city using the two-matching group pretest-posttest design. The experimental group consisted of (10) students and they received a psychodrama group counseling program, in order to reduce tension and enhance self-awareness. While the control group received nothing. Based on the results psychodrama is an effective tool to treat tension and enhance self-awareness. It is suggested that for future studies to be from different grades and both gender with larger sample size. It is also recommended to assess tension and self-awareness in different regions in Palestine.

Background and Aim: Broiler meat is susceptible to lipid oxidation due to its high content of unsaturated fatty acids, especially when stored for a long time. Concerning with that problem, we can add natural compounds to the animal feed, as the plant essential oils, which have antioxidant, antimicrobial, and antifungal activities. The objective of this study was to evaluate the antioxidant activity, fatty acid profile, and chemical composition of the meat of broilers fed with diets containing different essential oil, including lemongrass (Cymbopogon flexuosus) and pedestrian tea (Lippia aff. rotundifolia).

Materials and Methods: The experimental design used was a 4×4 factorial scheme (storage time×diets), and each treatment was repeated thrice. The treatments were applied as negative control (without antimicrobial); positive control (ration supplemented with 10 ppm of enramycin and 42 ppm of salinomycin), lemongrass (ration with 120 mg of essential oil of lemongrass for each kilogram of live weight of the animals), and pedestrian tea (ration with 120 mg of essential oil of pedestrian tea for each kilogram of live weight of the animals). Storage was performed after slaughter and evaluated monthly for 4 months.

Results: The inclusion of lemongrass oil and pedestrian tea in the broiler diet did not change the ether extract content of the meat sample obtained from thigh and drumstick. The storage time promotes an increase in the moisture loss of the meat from the 2nd month in all treatments. There was an interaction between the additive and storage time for moisture loss. In the 2nd month of storage, the meat from broilers fed the antibiotic-containing feed had a lower moisture loss than those from broilers in the other treatment groups. The fatty acid profile did not differ statistically between the different treatment groups. The inclusion of additives in the food dropped the lipid oxidation at the 2nd month of storage. From the 3rd month, however, only the essential oils showed antioxidant effect.

Conclusion: Antioxidant activity was positive for treatments that included essential oils. The lemongrass oil and pedestrian tea can be used as antioxidant additives in broiler diets to improve the oxidative stability of thigh-drumstick meat during storage. The results of the study suggest a good prospective for further research with profitability of usage essentials oils examined, for their economical application as feed components in broiler nutrition.

No artigo apresentamos discussões à luz dos pensamentos e contribuições do Grupo de Estudos de Educação e Relações de Gênero – GEERGE, da Universidade Federal do Rio Grande do Sul, referentes à Pedagogia Queer, sexualidades, relações de gênero e normatização presentes nos espaços escolares. Refletimos sobre uma padronização das pedagogias escolares, voltando o olhar para as crianças pequenas, às quais de alguma maneira tendem a resistir a essas normatizações hegemônicas e heteronormativas, difundidas como única e possível forma de viver e constituir as sexualidades. Buscamos compreender como ocorre a educação de meninos e meninas que subvertem essas fronteiras de padrões impostos, como estes corpos tornam-se invisíveis ao não se encaixarem na norma heterossexual. Quais as estratégias que a Pedagogia Queer oferece para tornar visíveis estes corpos, trazendo-os para ordem discursiva, do dizível.

Resumo: Este artigo objetiva entender em que condições históricas emerge a certificação por terminalidade específica (CTE) na Rede Federal de Educação Profissional, Científica e Tecnológica (RFEPCT). Trata-se de uma pesquisa assentada nos Estudos Culturais em Educação, que utiliza como lente analítica a noção de representação cultural, de Stuart Hall. O corpus empírico foi constituído de documentos oficiais sobre CTE. A análise mostrou a CTE – instrumento até então permitido apenas para o ensino fundamental no Brasil - adentrando historicamente a RFEPCT no final da primeira década do século XXI. Isso se produziu a partir do elo entre educação especial e educação profissional e tecnológica, que compartilham representações sobre a profissionalização e o autoempreendedorismo como caminhos para a garantia da inclusão dos sujeitos com deficiência mental grave e múltipla no mundo do trabalho.

Política de inclusão escolar e a modulação das condutas dos sujeitos com deficiência
Authors: Kraemer Graciele Marjana
Published: June 2021

O objetivo do presente estudo é analisar e problematizar como a política de inclusão escolar aciona tecnologias de modulação das condutas dos sujeitos com deficiência. A analítica que sustenta a problematização foi desenvolvida a partir do conceito foucaultiano de governamento. Verifica-se, por meio de pesquisa documental, que os investimentos operacionalizados via programas governamentais para promover a inclusão escolar potencializam um quadro político, econômico e social em que os efeitos da exclusão passem a ser atenuados. Como tecnologia de modulação das condutas das pessoas com deficiência, a participação é uma das condições elementares para a promoção da autonomia; essa condição, segundo a política de inclusão escolar, desenvolve-se a partir da configuração de investimentos na promoção da participação e do desenvolvimento individual.

Published: June 2021

Este artigo analisa as estratégias de governamento e as práticas de in/exclusão presentes no Projeto Assistencial Acreditar é Investir desenvolvidas sobre os estudantes do Ensino Fundamental, no contexto da Escola Municipal de Ensino Fundamental Cidade do Rio Grande. Em termos metodológicos a pesquisa organizou-se em três momentos: 1. análise de documentos que norteiam as ações do Centro e do Projeto; 2. entrevistas realizadas com profissionais que ocuparam distintas posições dentro do mesmo e 3. rede de narrações com estudantes que participam do projeto na condição de bolsistas ou aprendizes. A discussão e problematização teve como questão central: que estratégias são utilizadas pelo Projeto Acreditar é Investir para conduzir as condutas destes sujeitos dentro e fora da escola? Tendo como suporte os estudos foucaultianos, foi possível visualizar dois movimentos analíticos: num primeiro eixo, discutimos o processo de seleção dos jovens estudantes para participarem do projeto. Neste processo visualizamos as implicações na inclusão de alguns alunos no projeto e na exclusão de tantos outros que não são selecionados. Esses processos de in/exclusão subjetivam os sujeitos e produzem determinados comportamentos sociais adequados ao projeto. Num segundo eixo de análise, percebemos que as práticas de in/exclusão ocorrem não só no processo de seleção, mas persistem durante a permanência dos jovens que são selecionados. Isso ocorre por meio da imposição de condicionalidades, assim como das práticas de punição.

Web based Augmented Reality for Information Delivery Services A Performance Study
Authors: Roy Samrat Guha , Kanjilal Uma
Published: June 2021

Augmented Reality (AR) is the overlapping of the real world and the virtual world. AR is an evolving technology, and its implementation opens up a new direction to multiple types of information access services rendered to the users. The digital library section of the central library IIT Kharagpur has a rich collection of several items like CD/DVD ROMs, Digital Scanners, and VR Devices. Library developed in-house WebAR programs using “ar.js” that support “three.js” and “A-Frame” for Augmented Reality rendering on the web. This study tried to evaluate web-based AR programs’ performance on mobile devices with low-end hardware configuration supporting WebGL and WebRTC. We conducted quantitative research to find the performance of the web-based AR applications using the four independent variables, namely frames per second (fps), request animation frame (raf), load time (lt), entity object (eo). The paper is also helpful to the academic librarians who think about implementing augmented reality library services with no cost involved. The AR-based information service is beneficial to library users with new COVID norms1, as the user does not need to touch anything to get the information. Instead, it gets into his/ her mobile device.
Role of Librarians and Information Scientists in Plagiarism Control A Study of NIRF Ranked Engineering Institutions Ranked in 2020
Authors: Jilani Gulam , Ahmad Naved
Published: June 2021

The study was conducted to ascertain the role played by librarians and information scientists in controlling plagiarism in NIRF ranked engineering institutions ranked in 2020. With the application of knowledge of various types of resources and technological tools, librarians and information scientists play vital roles in making the awareness and fighting the disease of plagiarism. The students, research scholars and more importantly the faculty should be aware of plagiarism and its detrimental effects on their practices on their study & research and future career as well. The major objective of this study was to recognise the role played by librarians and information scientists in curbing plagiarism. Keeping this in view, a few research questions were framed. The study surveyed 200 NIRF ranked engineering institutions ranked in 2020 where engineering programs are being conducted. The researchers of this study found that majority of the librarians and information scientists (81.82 %) think that awareness about plagiarism is quite important while 89.92 per cent of them also ascertained that their institutions have plagiarism policy, and most of the institutions are using Turnitin and/or Urkund Anti-Plagiarism detection tool as well. The Librarians and Information Scientists make their users aware about plagiarism by promulgating the information through various activities through the library portals/websites as well as social media services. It was found that total 68.18 per cent respondents believe that ‘Orientation Programs and training’ is quite significant methods to make them aware about regulations against plagiarism and can discourage such intellectual theft and infringement. The study also reveals that the librarians should frequently conduct meetings with Head of Department, Faculty members and educators to discuss the issue and also deliver lectures to the faculty members, researchers as well as students.

We present various results about the combinatorial properties of line arrangements in terms of the Chern numbers of the corresponding log surfaces. This resembles the study of the geography of surfaces of general type. We prove some new results about the distribution of Chern slopes, we show a connection between their accumulation points and the accumulation points of linear H-constants on the plane, and we conclude with two open problems in relation to geography over ℚ and over ℂ.

Objectives

An increase in the incidence of congenital hypothyroidism (CH) with eutopic gland has been reported worldwide due to neonatal screening programs. In this study, we aimed to determine the prevalence of transient CH (TCH) and to investigate predictive factors that could distinguish between permanent and transient CH in patients with eutopic thyroid glands.

Methods

We retrospectively reviewed 508 children treated for CH with eutopic thyroid glands between June 1998 and June 2020 in Jiangxi Newborn Screening Center. All patients were treated with levothyroxine and underwent Diagnostic re-evaluation after 2–3 years of age. Patients were classified as having TCH or permanent CH (PCH) during follow-up.

Results

Of the 508 patients initially treated for CH with a normally located gland, 335 patients (65.9%) were classified in the TCH group and 173 (34.1%) in the PCH group based on the defined criteria. Multivariate analysis revealed that TCH was associated with a lower levothyroxine dose at 24 months of age (p<0.001) and a lower likelihood of having a first-degree family history of CH (p=0.026) than PCH. Gender, prematurity, low birth weight, initial CH severity such as serum TSH and FT4 levels, or bone maturation delay at diagnosis had no effect. Receiver operating characteristics curve analysis showed that a cutoff of 2.3 μg/kg/day for levothyroxine dose requirement at 24 months of age had a sensitivity of 71% and a specificity of 70% for predicting transient CH, with values below this threshold considered predictive of transient CH.

Conclusions

TCH presents a significant portion of patients with CH. The levothyroxine dose requirement at 24 months of age has a predictive role in differentiating TCH from PCH in CH patients with eutopic thyroid glands.

Objectives

Aldolase A deficiency also known as glycogen storage disease (GSD) XII, is an ultra rare autosomal recessively inherited GSD, associated with hemolytic anemia and rhabdomyolysis.

Case presentation

Here, we first report a patient with dermatological findings, hemodialysis requirement for rhabdomyolysis, and a novel likely pathogenic c.971C>T (p.A324V) mutation in the ALDOA gene.

Conclusions

Episodes of rhabdomyolysis can be triggered by febrile illnesses and catabolic processes. Diagnosis should be confirmed by the mutation analysis of ALDOA gene. Treatment includes management of hemolytic anemia and administration of antipyretics during febrile episodes to avoid hemolysis and rhabdomyolysis.
Rechtsfälle in der juristischen Ausbildung der Pandektenwissenschaft

Case studies as part of pandectistic legal education in 19th century Germany. The traditional image of the pandectistics rested on the assumption that legal education in this area, which inspired students from all over the world, relied exclusively on the logicsystematic pandect textbooks. These days we know that case studies, too, played an important role in addition to the primarily systematic pandect lectures. The pandectists studied the interpretation of legal problems, which were mainly inspired by court practise. This paper is unprecedented in using actual lecture notes to evaluate those solutions developed during the lectures which were not included in the printed case collections. It becomes clear that the technique used for solving legal problems differs as much from the relation method, which was applied by the courts in that period, as it differs from the so-called claim method, which is common in German legal education today.

Because of frequent high-temperature weather and increased traffic volume, the rutting of asphalt pavement has become the main technical problem to be resolved. In this paper, seven types of anti-rutting asphalt mixtures, including masterbatch hard asphalt mixture with high-modulus, additive-type anti-rutting asphalt mixture, styrene-butadiene-styrene modified asphalt, and intersection anti-pushing asphalt mixtures A, B, C, and D were proposed. The Chinese and French rutting tests, the flow number test, the evaluation method of anti-pushing performance, and the structural depth attenuation test were used to evaluate the applicability of the following anti-rutting test methods: the evaluation methods and indicators of anti-displacement performance and the evaluation methods and indicators of structural depth attenuation under high-temperature conditions. The test results showed that the dynamic stability (DS) index of the Chinese rutting test was more suitable for evaluating the first stage of rutting development, and the DS index was more suitable for evaluating the second stage of rutting development than the creep rate of the French rutting test. It was reasonable to use the French evaluation method for asphalt concrete (AC) mixtures. The Chinese rutting test was more suitable for the high-modulus asphalt mixture. In addition, improving the high-temperature stability of the asphalt mixture can slow down the attenuation of the anti-slipping property.
The Globalization of Production, Industrial Upgrading, and Collective Labor Rights in the Global South
Authors: Roberts Anthony
Published: June 2021

The impact of globalization on the enactment and practice of collective labor rights (CLR) in the global South remains a contested issue in the global political economy literature. Some scholars suggest southern firms and states suppress CLR to maintain global competitiveness in labor-intensive manufacturing. Other scholars contend that globalization improves CLR as globally integrated firms increasingly “upgrade” to more capital- and skill-intensive manufacturing. This study empirically adjudicates these claims by examining whether the integration of southern firms into global production networks indirectly affects CLR through the skill upgrading of the industrial labor force. I test this proposition using unbalanced panel data on collective labor laws and practices in 55 low- and middle-income countries from 1985 to 2002. Estimates from generalized path models show that greater manufacturing exports to northern countries and inward foreign direct investment stock are directly associated with a decrease in collective labor practices net of institutional, political, and macroeconomic conditions. Most importantly, I find that manufacturing exports indirectly reduce collective labor practices by decreasing the skill composition of the industrial labor force. Overall, this study provides novel evidence that the globalization of production directly reduces collective labor practices in the global South and indirectly reduces these practices through hindering skill development in industrial labor.
Cari açık ve doğrudan yabancı yatırımlar arasındaki ilişki: MIST ülkeleri için ampirik bir analiz
Authors: Ürüt Saygın Serap
Published: June 2021

Ülkelerin karşılaştıkları birçok temel makroekonomik sorun söz konusudur. Bu sorunlar arasında cari açık sorunu serbestleşme süreci ile birlikte ülkelerin oldukça sık karşılaştıkları sorunların başında gelmektedir. Özellikle gelişmekte olan ülkelerin ara malı ithalatına bağımlılığı yüksek cari açıklar verilmesini getirmektedir. Bu açıkların giderilmesinde ise doğrudan yabancı yatırımlar (DYY) ön plana çıkmaktadır. Bu çalışmada da, cari açıklar ve doğrudan yabancı yatırımlar arasındaki ilişkinin ampirik olarak incelenmesi hedeflenmiştir. Çalışmada, 1990-2019 dönemi verileriyle MIST (Meksika, Endonezya, Güney Kore ve Türkiye) ülkeleri özelinde panel eşbütünleşme testi yapılmıştır. Analiz sonucunda değişkenler arasında uzun dönemli bir ilişki tespit edilmiştir. Uzun dönemli ilişkinin etkisini ortaya koyabilmek amacı ile de ortalama grup dinamik en küçük kareler (DOLSMG) tahmincisinden yararlanılmıştır. Analiz sonucunda incelenen ülkelerden G. Kore hariç doğrudan yabancı yatırımların cari açığı negatif yönlü etkilediği sonucuna ulaşılmıştır. Panel DOLSMG test sonucuna göre panel genelinde DYY’nin esneklik katsayıs 1.22 dir. Yani DYY’deki 1 birimlik artış cari açığı 1.22 birim azaltmaktadır. Analizde incelenen diğer bir değişken olan ticari açıklığın ise cari açığı arttırdığı bulgusu elde edilmiştir. Ticari açıklıktaki 1 birimlik artışın cari açığı 0.11 birim arttırdığı sonucuna ulaşılmıştır.
A panel causality analysis of the relationship between financial development and economic growth in OECD countries
Authors: Küçüksakarya Sevilay
Published: June 2021

This study examines the relationship between financial development and economic growth. Thus, this study aims to find empirical shreds of evidence for the direction of the causality between financial development proxied by domestic credit to the private sector and per capita GDP growth by using the panel granger causality test of the Dumitrescu-Hurlin Test. For this purpose, we used a panel of 16 OECD countries from 2008 to 2019 to provide evidence of whether the supply leading hypothesis or demand following hypothesis or both holds. All econometric exercises are carried out for whole countries and high-income countries, and upper-middle-income country groups in the sample. Due to cross-sectional dependence among the sample countries, we determine the degree of integration of each variable by employing the second-generation panel unit root tests of CIPS. We continue our analysis with the panel causality test developed by Dumitrescu and Hurlin (2012) to determine the direction of the causality between variables. For this purpose, we performed three sets of causality analyses. In the first one, we include all countries in the panel. We then divided the countries into two sub-groups based on the income classification and the level of financial development in these countries proxied by domestic credit to the private sector. The causality test results, including all countries in the sample, indicate that the hypothesis holds the supply leading hypothesis during the sample period. This means that even though this panel contains countries with a development level, financial development still seems to be a pre-condition for economic growth for these nations. We also obtain the same results when we include high-income countries in the sample. The study results provide compelling evidence for the relationship between economic growth and financial development since the sample includes countries with different levels of financial development with different degrees of per capita GDP growth.
