Published: February 2023

Review question / Objective: The treatment of choice for patients of Parkinson's disease is levodopa. However, levodopa has been suggested to decrease Vit B12 level in these patients. Thus, the research question for this systematic review is whether vit B 12 supplementation in Parkinson's disease(PD) patients on treatment with levodopa improves vit B12 level effecting the Cognition, Motor functions and Mood instability among them in comparison to PD patients on levodopa treatment who are not supplemented with Vit B12. Condition being studied: Parkinson disease is the progressive degeneration of dopaminergic neurons present within the substantia nigra that can lead to altered movements along with the prevalence of cognitive and mood instability as a result of dopamine(neurotransmitter) deficiency. The most effective treatment for the Parkinson's disease is the administration of levodopa, a dopamine precursor . Long term treatment with levodopa causes an increase in homocysteine levels and tissue deficiency of vitamin B12 and folate may occur. Vitamin B12 supplementation is administered as after management regime, in Parkinson patient on levodopa treatment . This study aims to conduct a systematic review, of studies , randomized control trials investigating the ability of vitamin B12 supplementation to enhances the recovery/reduce the decline, if any, of the symptoms of cognitive, motor, mood impairments associated with Parkinson's disease patient on levodopa treatment.

A STUDY ON RESILIENCE DURING THE FIRST WAVE OF COVID-19 IN INDIA
Authors: Adak Chayan , Panda Bijoy Krishna , Sinha Muktipada
Published: February 2023

The coronavirus outbreak in early 2020 caused havoc on those directly afflicted, giving a chance to investigate the role of a variety of variables (protective behaviours) in resilience for individuals who were indirectly exposed. In an Internet convenience sample of 615 people, indices of assessed resilience were linked to mental relaxation strategies, involvement in household chores, confidence in survival, change in sleeping habits, and personal attribution during India's first countrywide lockdown. At the same time, perceived resilience was linked to survival and educational confidence. These findings emphasize the importance of education, survival thinking, family cohesiveness, and personal habits in helping people become stronger, more durable, and resilient people.
COMMUNITY RELATIONS MANAGEMENT IN CONTEMPORARY CORPORATE HOUSES
Authors: K P Divya Kumari
Published: February 2023

Modern organizations receive land, labor, capital, investors, distributors, consumers, image builders, events managers and other facilitators of organizational development. They are required to establish and maintain a mutually beneficial relationship with the communities since they are at the receiving end. Community relationship management is an important activity undertaken by the modern organizations. These organizations must cultivate civic responsibility and repay their gratitude to the local community. Community involvement is necessary to foster a sense of community teamwork for the sustainable development of the organization. A comprehensive community relations program enhances the visibility of organizations and brings the community closer to the organizational mainstream. Good community relations programs generate series of advantages to the organizations. New business opportunities also crop up on the basis of effective community relations programmes implemented by the modern organizations. The salient features of community relations management are primarily discussed in this paper on the basis of qualitative research methodology.

Published: February 2023

A produção tradicional de indicadores socioeconômicos, predominantemente atrelada aos produtores de estatísticas oficiais e públicas, tem a aferição da sua qualidade consolidada ao longo das últimas décadas com diversas publicações relativas a frameworks e manuais de orientações ou boas práticas. Entretanto, o fenômeno da Revolução dos Dados vem colocando uma série de desafios aos produtores ao trazer o big data como possibilidade de fonte de dados a servir de insumo para os processos de produção. Entre os desafios está o de como garantir a qualidade dos produtos estatísticos. Nesse contexto, este artigo se propõe a resumir a produção técnico-científica sobre a qualidade de indicadores socioeconômicos produzidos a partir de big data. Para tanto, é conduzida uma revisão sistemática integrativa. Como resultados, o artigo apresenta uma percepção sobre: quais os principais agentes envolvidos com o tema; quais dimensões e frameworks de qualidade têm sido considerados e propostos; e quais as lacunas de pesquisa – direcionando esforços e trabalhos futuros.
The Most wretched and the most blissful individuals in Brazil
Authors: Golgher André Braz , Coutinho Raquel Zanatta
Published: February 2023

Este artigo aborda os indivíduos mais desafortunados e mais felizes do Brasil por meio da World Values Survey de 2014. Esses grupos foram definidos com base em autoavaliações relativas à felicidade geral e satisfação com a vida. Compararam-se esses grupos com o restante da população brasileira por meio de análise de aglomerados e respostas a questões relacionadas a importância dada à família, a autoavaliação do estado de saúde, a religiosidade, a autodeterminação, a confiança e a situação financeira. Além disso, descreveram-se perfis particulares de indivíduos mais desafortunados e de pessoas mais bem-aventuradas. Por meio de modelos de regressão logit multinomial, investigou-se quais grupos sociodemográficos tinham maior chance de estar em cada perfil. Embora altamente heterogêneos, os indivíduos mais desarfortunados desfrutam de algumas características comuns, e o mesmo acontece com os indivíduos bem-aventurados. Enquanto os primeiros apresentavam uma situação financeira autoavaliada frágil e tinham baixos níveis de confiança, indivíduos bem-aventurados tinham altos níveis de autodeterminação e de religiosidade.
Análise do Programa de Subvenção ao Prêmio do Seguro Rural e seu impacto na área plantada e na produtividade agrícola dos segurados no Brasil
Authors: Tabosa Francisco José Silva , Vieira Filho José Eustáquio Ribeiro
Published: February 2023

Este estudo buscou avaliar o impacto do Programa de Subvenção ao Prêmio do Seguro Rural (PSR) na área plantada e na produtividade dos produtores assegurados no Brasil. Para isso, utilizaram-se informações estaduais sobre número de produtores, número de apólices, área plantada, importância assegurada e produtividade dos produtores assegurados entre os anos de 2006 a 2018. O procedimento metodológico baseou-se em vetores autorregressivos (VAR) para dados em painel. Os resultados mostraram que, no programa avaliado, existe uma grande concentração de produtores e de apólices contratadas nas regiões Sul, Sudeste e Centro-Oeste, principalmente nos estados do Paraná, Santa Catarina, Rio Grande do Sul, São Paulo, Minas Gerais, Goiás e Mato Grosso. Além disso, o número de produtores e a importância assegurada impactaram positivamente, no curto prazo, a produtividade do assegurado, sendo esse efeito prorrogado até seis anos, em média. No que se refere à área plantada, somente a importância assegurada teve um efeito positivo. O número de apólices, contudo, obteve um impacto negativo, tanto na área plantada, quanto na produtividade do assegurado.
Segurança alimentar, composição domiciliar e pobreza no Brasil : um estudo a partir dos microdados da PNAD para o período 2004-2013
Authors: Tavares Lucas Hermanny da Silva , Lima Ana Carolina da Cruz
Published: February 2023

O artigo analisa os microdados sobre segurança alimentar da Pesquisa Nacional por Amostra de Domicílios (PNAD) nos anos de 2004, 2009 e 2013, com o objetivo de evidenciar as especificidades das dinâmicas de domicílios com crianças e adolescentes em comparação àqueles nos quais há somente adultos. São analisadas as relações entre insegurança alimentar e programas de transferências de renda. Observa-se uma redução significativa nos níveis de insegurança alimentar dos domicílios com crianças e adolescentes no período analisado, porém a situação ainda é desfavorável nessas unidades domiciliares que, de modo geral, têm renda per capita inferior ao grupo de comparação, o que sugere uma maior vulnerabilidade de renda. Nos modelos de regressão logística, os efeitos das transferências de renda reduzem a probabilidade de insegurança alimentar grave, o que sugere que as transferências de renda são capazes de amenizar a insegurança alimentar, porém não são suficientes para erradicá-la. Observa-se que a situação é mais crítica nos domicílios com crianças em idade de primeira infância.
Does proximity matter? The effect of financial sector development on economic growth in the EAC and SADC regional blocs
Authors: Alananga Samwel , Mutasa Felician
Published: February 2023

This study examines the finance-growth nexus among countries in the Southern African Development Community and East Africa Community regional blocs. We aim to see if small economies can rely on expansionary monetary policies to stimulate economic growth given the illusive nature of such policies. The panel error correction model is applied to analyze the aggregated data, which were obtained from the World Development Indicators and the Comité Européen d'Etudes des Polyphosphates. The results indicate that proximity to trading giants jeopardizes the freedom to use monetary expansionary policies among relatively small countries. If such policies are adopted, it will be a significant impact on countries located in regions where trading powers are evenly distributed.

Published: February 2023

Building information Modeling (BIM) has been applied to the whole life cycle planning of construction projects, becoming the latest “engineering brain”. Currently, researches on BIM involve various stages, but most of the review fields are relatively single and lack of systematic review and analysis. In order to comprehensively analyze the research trend of BIM in the field of engineering management, this paper takes the holistic analysis method as the framework. In the first stage, 2066 research projects were quantitatively analyzed by bibliometrics to clarify their research environment. In the second stage, scientometric analysis method is adopted to identify scholars, countries, key words and journal sources that have achieved fruitful results and influence in BIM research, and to clarify the research environment. In the last stage, indepth qualitative discussion is carried out to achieve three objectives: (1) to divide the whole life cycle of the article and summarize the research hotspots in each stage; (2) identify BIM application problems; (3) determine the future research direction. This work is helpful for researchers and practitioners in this field to quickly find influential and fruitful research or journals, and to understand the current research hot spots and trends for the next research planning.

We present an 870 μm continuum survey of 300 protostars from the Herschel Orion Protostar Survey using the Atacama Compact Array (ACA). These data measure protostellar flux densities on envelope scales ≤8000 au (20″) and resolve the structure of envelopes with 1600 au (4″) resolution, a factor of 3–5 improvement in angular resolution over existing single-dish 870 μm observations. We compare the ACA observations to Atacama Large Millimeter/submillimeter Array 12 m array observations at 870 μm with ∼0.″1 (40 au) resolution. Using the 12 m data to measure the fluxes from disks and the ACA data within 2500 au to measure the combined disk plus envelope fluxes, we calculate the 12 m/ACA 870 μm flux ratios. Our sample shows a clear evolution in this ratio. Class 0 protostars are mostly envelope-dominated with ratios <0.5. In contrast, Flat Spectrum protostars are primarily disk-dominated with ratios near 1, although with a number of face-on protostars dominated by their envelopes. Class I protostars span the range from envelope to disk-dominated. The increase in ratio is accompanied by a decrease in the envelope fluxes and estimated mass infall rates. We estimate that 80% of the mass is accreted during the envelope-dominated phase. We find that the 12 m/ACA flux ratio is an evolutionary indicator that largely avoids the inclination and foreground extinction dependence of spectral energy distribution-based indicators.
Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
Authors: Li Shuo , Zhong Shiyan , Berczik Peter , Spurzem Rainer , Chen Xian , Liu F. K.
Published: February 2023

By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how different stellar components evolve during the merger, we generate evolved stellar distributions with an initial mass function. Special schemes have also been developed to deal with some rare but interesting events, such as the tidal disruption of main-sequence stars, plunging low-mass stars, white dwarfs, neutron stars and stellar-mass black holes, and the partial tidal disruption of red giants or asymptotic giant branch stars. Our results indicate that the formation of a bound SMBH binary will enhance the capture rates of stellar objects by SMBHs. Compared to the equal stellar mass model, the multi-mass model tends to result in a higher average mass of disrupted stars. Instead of being tidally disrupted by the SMBH, roughly half of the captured main-sequence stars will directly plunge into the SMBH because of their small stellar radii. Giant stars, on the other hand, can be stripped of their envelopes if they are close enough to the SMBH. Though most remnants of the giant stars can survive after the disruption, a small fraction still could plunge into the SMBH quickly or after many orbital periods. Our results also indicate significant mass segregation of compact stars at the beginning of the merger, and then this effect is destroyed as the two SMBHs form a bound binary.
FEASTS: IGM Cooling Triggered by Tidal Interactions through the Diffuse H i Phase around NGC 4631

We use the single-dish radio telescope Five-hundred meter Aperture Spherical Telescope (FAST) to map the H i in the tidally interacting NGC 4631 group with a resolution of 3.′24 (7 kpc), reaching a 5σ column density limit of 1017.9 cm−2 assuming a line width of 20 km s−1. Taking the existing interferometric H i image from the Hydrogen Accretion in LOcal GAlaxieS project of Westerbork Synthesis Radio Telescope as a reference, we are able to identify and characterize a significant excess of large-scale, low-density, and diffuse H i in the group. This diffuse H i extends more than 120 kpc across, and accounts for more than one-fourth of the total H i detected by FAST in and around the galaxy NGC 4631. In the region of the tidal tails, the diffuse H i has a typical column density above 1019.5 cm−2, and is highly turbulent with a velocity dispersion of around 50 km s−1. It increases in column density with the dense H i, and tends to be associated with the kinematically hotter part of the dense H i. Through simple modeling, we find that the majority of the diffuse H i in the tail region is likely to induce cooling out of the hot intragalactic medium (IGM) instead of evaporating or being radiatively ionized. Given these relations of gas in different phases, the diffuse H i may represent a condensing phase of the IGM. Ongoing and past active tidal interactions may have produced the wide-spreading H i distribution, and triggered the gas accretion to NGC 4631 through the phase of the diffuse H i.
Stability of Parker's Steady Solar Wind Solution in the Subcritical Region
Authors: Shivamoggi Bhimsen K.
Published: February 2023

Parker’s steady solar wind solution (PSSWS) is a physically acceptable solution describing a smooth acceleration of the solar wind to supersonic speeds. Parker proposed that PSSWS possesses an intrinsic stability, like a “stable attractor” of this dynamical system. With a view to give a systematic analytical development, we restrict ourselves to the subcritical region inside the Parker critical point (PCP) where the solar wind goes through sonic flow conditions. This enables one to avoid the singularity at PCP plaguing the linear stability problem. Following Parker, we approximate the corona in the subcritical region by a static atmosphere and amend it to include an azimuthal flow and a weak radial flow. These physical simplifications enable us to pose a Sturm–Liouville problem for linearized perturbations about PSSWS. PSSWS is shown to have an intrinsic stability in the subcritical region, while leaving the solar coronal base in a state of (1) rest, (2) corotation with the Sun, and (3) slow radial motion. This result is also shown to hold when a diabatic flow in near-isothermal conditions is included in Parker’s model to explicitly account for the extended coronal heating. The isothermal gas assumption in Parker’s model is then relaxed, and a more realistic barotropic fluid representing variable extended active coronal heating conditions is considered for the gas flow. The stability of PSSWS, as the solar wind flow emerges from a state of rest at the solar surface, is shown to continue to hold.
Solar-cycle and Latitude Variations in the Internetwork Magnetism
Authors: Trelles Arjona J. C. , Martínez González M. J. , Ruiz Cobo B.
Published: February 2023

The importance of the quiet-Sun magnetism is that it is always there to a greater or lesser extent, being a constant provider of energy, independently of the solar cycle phase. The open questions about the quiet-Sun magnetism include those related to its origin. Most people claim that the local dynamo action is the mechanism that causes it. This fact would imply that the quiet-Sun magnetism is nearly the same at any location over the solar surface and at any time. Many works claim that the quiet Sun does not have any variation at all, although a few of them raise doubt on this claim and find mild evidence of a cyclic variation in the the quiet-Sun magnetism. In this work, we detect clear variations in the internetwork magnetism both with latitude and solar cycle. In terms of latitude, we find an increase in the averaged magnetic fields toward the solar poles. We also find long-term variations in the averaged magnetic field at the disk center and solar poles, and both variations are almost anticorrelated. These findings do not support the idea that the local dynamo action is the unique factory of the quiet-Sun magnetism.

Introduction: Covid Convalescent Plasma (CCP) failed to demonstrate its efficacy in severe and life-threatening coronavirus disease 2019 (COVID-19) cases. However, the role of CCP in hospitalized moderate cases is unclear. This study aims to examine the efficacy of administering CCP to hospitalized moderate coronavirus disease 2019 patients.
Methodology: An open-label randomized controlled clinical trial design was used from November 2020 – August 2021 at two referral hospitals in Jakarta, Indonesia, and the primary outcome was mortality at 14 days. The secondary outcomes were mortality at 28 days, the time-to-discontinuation of supplemental oxygen, and the time-to-hospital discharge.
Results: This study recruited 44 subjects, and the intervention arm consisted of 21 respondents who received CCP. The control arm consisted of 23 subjects who received standard-of-care treatment. All subjects survived during the fourteen-day follow-up period, and the 28-day mortality rate in the intervention group was lower than the control (4.8% vs 13.0%; p = 0.16, HR = 4.39 (95% CI = 0.45-42.71). There was no statistically significant difference in the time-to-discontinuation of supplemental oxygen and time-to-hospital discharge. During the total follow-up period (41 days), the mortality rate in the intervention group was also lower than the control (4.8% vs 17.4%, p = 0.13, HR = 5.47, 95% CI = 0.60–49.55).
Conclusions: This study concluded that in hospitalized moderate COVID-19 patients, CCP did not reduce 14-day mortality compared to the control. Mortality during 28 days and total length of stay (41 days) were lower in the CCP group compared to the control, although they did not reach statistical significance.
The Association between Coffee Consumption and Non-Alcoholic Fatty Liver Disease: Is there a Protective Role?
Authors: Nadi Anass , Oulammou Zineb , Maizi Meryem , Delsa Hanane , Rouibaa Fedoua
Published: February 2023

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease. Several studies have suggested a protective role of coffee in chronic liver disease, but their results remain controversial.
AIM: The purpose of the study was to investigate the association between coffee consumption and the prevalence and severity of NAFLD in a non-diabetic and non-alcoholic population.
METHODS: This study involved 157 participants. Cases were defined by the presence of steatosis on liver ultrasound, the severity of which was assessed by the Bright Liver Steatosis Score. Controls were defined by the absence of steatosis on liver ultrasound. All patients with cytolysis and/or cholestasis had an etiological investigation (serologic testing for Hepatitis B virus and hepatitis C virus infection, and autoimmune investigation). All participants underwent liver ultrasound, clinical assessment (blood pressure, waist circumference, and body mass index (BMI)), and biological assessment (Complete Blood Count, lipid profile test, liver function tests, and Fasting Blood Glucose [FBG]). Dietary assessment was conducted using a food frequency questionnaire, coffee consumption was dichotomized into present or absent and then categorized according to the number of cups consumed per day.
RESULTS: The study included 94 NAFLD and 63 controls, the two groups were comparable in demographic characteristics. The means of systolic blood pressure, BMI, waist circumference, Aspartate Transaminase, Alanine Transaminase (ALT), Gamma-Glutamyl transferase (GGT), alkaline phosphatase, and FBG were significantly higher in the NAFLD group. The study of the association between coffee consumption and NAFLD showed a significant decrease in the risk of its occurrence (Odds Ratios [OR] = 0.39) and its severity (OR = 0.32) in coffee consumers, mainly in those consuming 3 or more cups. In multivariate analysis, the following factors were associated with increased prevalence of NAFLD: Metabolic syndrome, high mean levels of alkaline phosphatase, GGT, ALT, FBG, BMI, and waist circumference. However, Green tea consumption was not associated with either prevalence or severity of NAFLD (OR = 1.02, p = 0.82).
CONCLUSION: Coffee consumption is inversely associated with the prevalence and severity of NAFLD. Further prospective studies are needed to establish a cause-effect relationship between coffee and NAFLD.
Evolution of pollen grain morphology in Amorimia W.R. Anderson and allies (Malpighiaceae)
Authors: Silva Carolina Prandi , Almeida Rafael Felipe , Gasparino Eduardo
Published: February 2023

Background and aims: The genus Amorimia W.R. Anderson (Malpighiaceae), was recently segregated from species previously treated as the genus Mascagnia Bertero and then subdivides into two subgenera Amorimia subgenus Amorimia and Amorimia subgenus Uncinae, based on morphological and molecular data. Pollen grains have been used to improve the taxonomic classification of many ranks (i.e., species, genus, family) over the past two centuries. The pollen grains of the species of Amorimia were not previously analyzed. Therefore, we  descibe in detail the pollen morphology of 13 (out of 15) species of Amorimia, 1 species of Mascagnia Bertero and 1 species of Ectopopterys W.R. Anderson and reconstruct the phylogeny framework to understand the patterns of micromorphological pollen evolution in the genus. 

Material and Methods: The pollen grains were acetolysed, measured and photographed under light microscope. The quantitative data were submited to a multivariate analysis and were also made a character-mapping to identify which pollen characters are important in distinguishing species.

Key Results: The pollen grains of the analyzed species are monads, apolar, medium to large, with circular amb, oblate-spheroidal to prolate-spheroidal, presenting apertures that may be 3-colporate, with long and narrow colpi and circular endoaperture (Ectopopterys), 6- porate (Amorimia) or 8-porate (Mascagnia). Exine presenting a rugulate  ornamentation which may or may not have areolate or psilate areas close to the pore or distributed by the surface of the pollen grain.

Conclusion: According to the results of this study, Amorimia is a stenopolinic genus and the characteristics of the pollen grains are importante to segregate the genus. Nonetheless, there characteristics do not corroborate with the subdivision of this genus.
A Phenome-Wide Association Study of Drugs and Comorbidities Associated With Gastrointestinal Dysfunction in Systemic Sclerosis
Authors: Maclean Rory H. , Ahmed Fiza , Ong Voon H. , Murray Charles D. , Denton Christopher P.
Published: February 2023

Objective

To explore the causes of and contributors to gastrointestinal (GI) dysfunction in systemic sclerosis (SSc) in a phenome-wide association study (PheWAS), using real-world clinical records data.

Methods

Twelve thousand five hundred thirty-five documented clinical assessments of 2058 consenting individuals with SSc at the Royal Free Hospital (UK) were available for detailed phenotyping. Diagnoses and drugs were mapped to structured dictionaries of terms (Disease Ontology project and DrugBank Open Data, respectively). A PheWAS model was used to explore links between 6 important SSc-GI domains (constipation, diarrhea, dysmotility, incontinence, gastroesophageal reflux, and small intestinal bacterial overgrowth [SIBO]) and exposure to various comorbidities and drugs. “Hits” from the PheWAS model were confirmed and explored in a subcohort reporting quantitative GI symptom scores from the University of California Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract Instrument 2.0 (GIT 2.0) questionnaire.

Results

One thousand five hundred forty-six individuals were entered into the PheWAS analysis. Six hundred seventy-three distinct diagnoses and 634 distinct drugs were identified in the dataset, as well as SSc-specific phenotypes such as antinuclear antibodies (ANA). PheWAS analysis revealed associations between drugs, diagnoses, and ANAs with 6 important SSc-GI outcomes: constipation, diarrhea, dysmotility, incontinence, reflux, and SIBO. Subsequently, using GIT 2.0 symptom scores links with SSc-GI were confirmed for 22 drugs, 4 diagnoses, and 3 ANAs.

Conclusion

Using a hypothesis-free PheWAS approach, we replicated known, and revealed potential novel, risk factors for SSc-GI dysfunction, including drug classes such as opioid, antimuscarinic, and endothelin receptor antagonist, and ANA subgroup.
Engagements et processus de politisations au sein de la Convention citoyenne pour le climat
Authors: Blanc Nathalie , Granchamp Laurence
Published: February 2023

Notre propos est d’éclairer l’engagement citoyen au cours de la Convention citoyenne pour le climat (France, 2019-2021). Cette assemblée instaure un cadre original d’action collective et invite à réfléchir à ses effets sur les « engagements », soit la propension des participant·es à adopter le sujet débattu comme cause d’investissement personnel. Dans un premier temps, nous étudions les « processus » d’engagement afin d’élargir la compréhension des formes et des discours de l’engagement, en associant les aspects personnels et intimes, à la participation aux débats en vue d’élaborer les mesures à transmettre au gouvernement. Dans un deuxième temps, l’article rend compte des politisations à l’œuvre, entre autres à travers deux exemples de mesures : l’éthique alimentaire et l’écocide, emblématiques de ce « débordement » qui relève, comme nous le montrons, d’une politisation. Dans un troisième temps, nous nous intéressons aux effets de la Convention sur les formes et les dynamiques d’engagement a posteriori . Le travail d’enquête, fondé sur des observations conduites notamment au sein du groupe Se nourrir et des entretiens réalisés après la Convention, s’ancre dans une perspective pragmatiste d’étude des mobilisations, accordant de l’importance aux situations d’engagement.
Une participation entre technique et politique . Typologie des mesures de la Convention citoyenne pour le climat
Authors: Tilikete Selma
Published: February 2023

L’homogénéité formelle des six cents pages du rapport final de la Convention citoyenne pour le climat française (CCC) donne peu d’indices sur ce qu’a pu être le processus d’élaboration des propositions. Pourtant, différentes formes de répartition des rôles entre citoyen·nes et expert·es ont eu lieu pour répondre au mandat, donnant lieu à des mesures allant de la révision constitutionnelle à l’élaboration de seuils et au calendrier de rénovation énergétique des bâtiments. Cet article propose une typologie des mesures de la Convention, construite à partir de plusieurs critères : leur origine, le nombre et la motivation des porteuses et porteurs de la mesure, les types d’arguments utilisés, l’existence de désaccords et leur traitement, la fréquence et la nature de l’appui des expert·es. Grâce à ces critères, des mesures de cinq types ont été distinguées que nous avons choisi de nommer : génériques sectorielles, techniques, de sobriété, de régulation économique, et fondamentales. Si les procédures de la CCC ont été assez souples pour faire émerger cette diversité de réponses au problème climatique, toutes n’ont pas connu un terrain également favorable. Nous en discutons les enjeux politiques, en montrant comment chaque type coproduit à la fois une conception de l’environnement, et une conception de la participation des citoyen·nes tiré·es au sort aux décisions politiques pour répondre au défi climatique.
Les marges du dicible dans et hors d’un dispositif de participation instituée : les audits citoyens de la dette à Madrid
Authors: Bailly Jessy
Published: February 2023

Cet article interroge à nouveaux frais les dynamiques à l’œuvre dans les dispositions de participation instituée, à partir de ce qu’il est possible d’y dire et d’y faire entendre. On part de l’expérience d’un collectif d’audit citoyen de la dette à Madrid qui, s’il voit le projet militant dont il est porteur s’institutionnaliser par le nouvel exécutif élu en 2015, s’en estime pourtant insatisfait. Alors que la consécration du dispositif a permis de reformuler la manière de parler de la dette publique, les auditeurs-citoyens et auditrices-citoyennes considèrent que l’ordre du discours institutionnel, certes renouvelé, s’est heurté à leurs tentatives d’imposer leur propre lecture du problème de la dette publique.

This methodology allows proposing a conceptualization of the SSC and incorporate new elements of analysis.Findings: The results show that much of the innovation and instrumentalization of supply chains involves incorporating digital services to expand their functionalities, especially in terms of agility and connectivity. The servitization of supply chains is therefore a key new feature.  Put in relation to other characteristics identified in the literature, a cycle of continuous improvement is proposed as a conceptual structure for the SSC.Originality/value: This study contributes to strengthening the theoretical foundations of SSCs and serves as a guide for researchers and practitioners.
Long-time analysis of a stochastic chemostat model with instantaneous nutrient recycling
Authors: Guo Xiaoxia , Ruan Dehao
Published: February 2023

This paper presents long-time analysis of a stochastic chemostat model with instantaneous nutrient recycling. We focus on the investigation of the sufficient and almost necessary conditions of the exponential extinction and persistence for the model. The convergence to the invariant measure is also established under total variation norm. Our work generalizes and improves many existing results. One of the interesting findings is that random disturbance can suppress microorganism growth, which can provide us some useful control strategies to microbiological cultivation. Finally, some numerical simulations partly based on the stochastic sensitive function technique are given to illustrate theoretical results.

Authors: Fox Joanna , Videmšek Petra
Published: February 2023

In this article we discuss the nature of service user involvement in Higher Education (HE) social work programmes in both England and Slovenia. This discussion is based on our experiences of supporting such programmes alongside evidence derived from the literature. Firstly, we present a discussion of the effective development of service user involvement in the respective HEIs in our two countries. Secondly, we explore how the involvement of experts-by-experience in HEIs benefits the learning of social work students. Thirdly, we investigate how the emergence of Covid-19 has influenced the delivery of social work education and the involvement of service users in our respective social work programmes. We conclude by noting that our social work programmes have been forced to adapt to the needs of students in an online community and have embraced inclusive education. As a result of this, we suggest that the needs of experts-by-experience should inform the development of social work education and that they should be consulted on how they choose to be involved in educational practice. Key words experiential knowledge, expertise-by-experience, service user involvement, England, Slovenia
The Role of Quizlet Learning Tool in Learners' Lexical Retention: A Quasi-Experimental Study
Authors: Nguyen Long Quoc , Le Ha Van
Published: February 2023

The integration of technologies into education, especially language learning, has become more prevalent in this information age. One of the widely used tools for supporting second language (L2) vocabulary acquisition is Quizlet. Despite its increased popularity, empirical research on the effectiveness of Quizlet in enhancing L2 learners' lexical retention is still limited. Furthermore, most works primarily used conventional statistical methods such as t-tests or ANOVA, which might generate errors of Type I and II. This study aims to fill in these gaps by examining the impact of Quizlet on the lexical gains of EFL students at a private institution in Vietnam. Fifty-nine undergraduates participated in the study and were separated into two groups. The control group (n=28) did not utilize Quizlet during the in-class lessons, while the experimental group (n=31) revised vocabulary using Quizlet on a weekly basis. During four weeks, the experimental group reviewed thirty-two target words, divided into four sets (one set including eight items). Each set was utilized for one week in class under the supervision of the teacher. The data from the pretest and posttest were analyzed using Generalized Linear Mixed Model to generate more reliable statistics. The results demonstrated that learners in the experimental group achieved significantly better scores than those in the control group. Therefore, it could be concluded that Quizlet should be implemented in the classroom as a review or practice activity on a regular basis.

The prefabricated building course is a highly theoretical and practical specialized course with strong professionalism and extensive teaching contents. The teaching of prefabricated concrete structures is a significant link in prefabricated building construction and an important direction of cultivating talents applied to prefabricated building construction. Previous teaching features single teaching models, focuses on teaching materials, and highlights theoretical teaching, resulting in students’ low learning initiatives and poor practical ability. In order to improve the teaching effect and students' practical ability, Building Information Modeling (BIM) simulation technology was integrated into the teaching and practice of the prefabricated building courses. Then, the three-stage (guidance of real-scene cases, practical operation based on division of project work, and drawing cross-review) course teaching approach was proposed. With the construction of a prefabricated concrete structure in Hefei Metro of China as an example, students were asked to perform component modeling, assembly, and construction simulation via BIM. Results show that the teaching contents are completed, and the teaching effect is evidently strengthened. Students’ abilities to understand, analyze and practice actual engineering problems are evidently improved, and their problem-solving and practical ability in the aspect of prefabricated buildings is cultivated.

This experiment conducted using 20 Rahmani ewes at the last third of pregnancy in two equal groups. One group served as control, while the other group received Spirulina platensis (SP) at the rate of 0.5 gm 10 kg-1 live body weight. The objective was to find out the effect of adding Spirulina platensis algae to small ruminant rations on reproductive and productive traits and blood components of sheep. The experiments lasted for 120 days for both dams and their lambs after weaning. The findings proved that adding SP in ewes' diets had no effect on the average of live body weight change. Average milk yield was significantly (p <0.01) higher in the treatment group than the control. Lamb's birth weight and daily body gain of the treated group were significantly (p <0.01) higher than the control. Blood and serum picture profile of ewes were significantly higher when fed SP additive than the control. It could be concluded that the addition of SP to the ration of sheep positively preserved their health, productive and reproductive status as well as their lambs' growth rate. Also the additive improved the economic efficiency of treated animals by about 53.13%.
Using canonical correlation analysis to understand the rumen biohydrogenation patterns of linoleic and alpha-linolenic acids in the rumen fluid of bovines
Authors: Castillo Vargas Julián Andrés
Published: February 2023

The objective of this study was to determine the multivariate relationship among linoleic acid, alpha-linolenic acid, and their main rumen biohydrogenation (BH) intermediates and products in bovine rumen fluid using canonical correlation analysis (CCA). A dataset consisting of 1177 observations generated by 107 in vitro rumen incubation systems of pure and mixed linoleic acid (18:2-c9, c12) and alpha-linolenic acid (18:3-c9, c12, c15) was gathered. Two canonical variates were defined: A: composed of the nine main BH intermediates and products (18:2-c9, t11; 18:2-t11, c15; 18:1-t11; 18:1-t9; 18:1-t6; 18:1-c11; 18:1-c6; 18:1-c9; 18:0) of 18:2-c9, c12 and 18:3-c9, c12, c15 and B: composed of 18:2-c9, c12 and 18:3-c9, c12, c15. Two canonical functions between A and B with significant canonical correlations (R1=0.990 and R2=0.738; p <0.01) were obtained. However, only the first function was selected for CCA. Exploration of canonical loadings for first function, revealed the following quantitative significance (absolute value) order for fatty acids (FA) within their respective canonical variates: A: 18:0(0.958)>18:1-t9(0.837)>18:1-c11(0.835)>18:1-c6(0.824)>18:1-t11(0.747)>18:1-c9(0.738)>18:1-t6(0.415)>18:2-t11, c15(0.387)> 18:2-c9, t11(0.239); B: 18:2-c9, c12(0.667)>18:3-c9, c12, c15(0.488). The CCA showed that 18:2-c9, c12 has a greater contribution than that of 18:3-c9, c12, c15 on the production of the aforementioned BH intermediates, in which 18:0, as well as the groups of 18:1 cis and trans-FA were mainly affected.
Nutrient compositional variation and interrelationship in the muscle of wild and plastic-reared brachyuran
Authors: Moruf Rasheed Olatunji
Published: February 2023

Edible brachyurans are recognized as a popular source of food due to their delicious taste and nutritional quality. This study investigated the nutrient compositional variation and interrelationship in the muscle of wild and plastic-reared Cardisoma armatum. The plastic-reared crab had 27.81 ± 2.29 g 100 g-1 protein while crab from the wild contained 22.45 ± 2.65 g 100 g-1 protein. The difference in protein content of plastic-reared and its counterpart from the mangrove swamp was not significantly different (p > 0.05). This is also true of other proximate composition except that wild crabs were slightly higher in both crude fat (2.68 ± 0.35 g 100 g-1) and carbohydrate (5.89 ± 3.05 g 100 g-1). Generally, the total energy contributed due to protein, carbohydrate and fat in the tissues of both wild and plastic-reared C. armatum are similar. In the wild crab, contents of calcium (16083.27 ± 2127.90 mg 100 g-1) and phosphorus (1191.42 ± 199.21) were relatively higher, while contents of magnesium (368.69 ± 111.05 mg 100 g-1), sodium (125.30 ± 11.18 mg 100 g-1) and potassium (87.36 ± 7.27 mg 100 g-1) were relatively higher in plastic-reared crabs. All significant mineral ratios in wild and plastic-reared C. amartum fall within acceptable range. The positive relationship in the nutritional quality indicates that changes in proximate composition are associated with changes in mineral contents of the crab tissue.
