Au risque de la psychanalyse…
Authors: Fournier Sébastien 
Published: April 2020

Depuis plusieurs années, il est possible d’entendre, ici et là , que la psychanalyse est en crise, qu’elle est inévitablement vouée à disparaître. Sa pratique comme sa théorie font l’objet de nombreuses critiques. La méfiance (ou plutôt la défiance) est de rigueur. Dans ce contexte, il semble plus que jamais pertinent de s’interroger : pourquoi ce rejet de la psychanalyse ? Ne faut-il pas y voir l’expression d’un symptôme ?
Non-marital childbearing of migrants and their descendants: Russians in Estonia compared with Russians in Russia and Estonians
Authors: Sakkeus Luule , Abuladze Liili , Rahnu Leen , Puur Allan 
Published: April 2020

Pour expliquer l’émergence de comportements alternatifs en matière de famille et de fécondité, l’article mobilise des cadres explicatifs concurrents : rapport à la modernité et position sociale défavorisée. À partir des données recueillies dans le cadre de l’enquête sur les générations et les rapports de genre dans les deux pays (2004-2005), notamment auprès des femmes nées entre 1924 et 1986, il saisit les modèles de fécondité au regard de la parité chez des couples mariés et non-mariés, en comparant les migrants et descendants russes en Estonie aux populations autochtones en Estonie et en Russie. L’article établit que c’est parmi les Estoniens et les Russes (migrants) en Estonie que les naissances hors mariage sont les plus fréquentes, ce qui permet à ces auteurs de conclure que la culture et la socialisation (et non la position sociale) façonnent de manière déterminante ces différences en terme de fécondité.

Published: April 2020

A contabilidade é fortemente desafiada a reconhecer e mensurar as informações de forma relevante e autêntica mantendo-as hodiernas, de acordo com o que afirma o CPC 00 para atender as necessidades dos usuários nas mais diferentes esferas de atuação. Uma vez que o Conselho de Normas Internacionais de Contabilidade, responsável pela padronização as normas internacionais, ainda não se posicionou sobre o tratamento contábil das moedas virtuais e a mesma, sendo uma moeda descentralizada, não dispõe de um órgão regulador que discipline seus usos e registros, a contabilidade deve buscar alternativas, padrões na jurisprudência contábil para solucionar essas movimentações. O presente trabalho tem como objetivo geral identificar como as atividades realizadas em Bitcoins são reconhecidas sob a perspectiva da contabilidade junto aos órgãos responsáveis pela regulamentação e incidência de tributos sobre transações econômicas. Os procedimentos técnicos adotados foram à pesquisa bibliográfica e o estudo de caso. Conclui-se pela necessidade da criação de uma lei que regularize as moedas virtuais em defesa e segurança do usuário, descartando a intervenção estatal, uma vez que esta foi a falha das moedas virtuais que vieram anteriormente e, até que isso se concretize, sugere-se fazer a cotação dos Bitcoins já em uso empregando a cotação da exchange responsável.
Evaluating the Impact of Rural Finance on Cocoa Farmers Productivity: A Case Study of Bodi District in Ghana
Authors: Attipoe Sonny Gad , Jianmin Cao , Opoku-Kwanowaa Yaa 
Published: April 2020

Background: Agricultural finance from rural and community banks play a major role in increasing both yield and income of rural farmers in agricultural-dependent economies. These finances are needed for purchasing raw materials, paying labor fees and buying farming equipment, etc. However, substantial evidence about their roles in improving farm productivity is lacking, especially in the cocoa sector in Ghana, where rural and community banks are the forerunners in advancing credit to cocoa farmers in Ghana’s deprived rural cocoa-growing communities. This research, therefore, seeks to determine the impact of rural and community banks’ credit on cocoa farmers' productivity in the Bodi District of Ghana.
Methodology: Using random sampling method, a cross-sectional data of 350 cocoa farmers from 5 operational areas (Afere, Bodi, Amoaya, Kama and Suino) located in Bodi District in the Western region. The data were analyzed using descriptive statistics and logistic regression models. Statistical software (SPSS v20 and STATA v14) were used to analyze quantitative data on cocoa productivity.
Results: The results revealed that cocoa farmers with access to credit experienced significant yield increase (p<0.05) with a mean of 359.71 kgha-1 as compared to 235.30 kgha-1 for non-credit takers. Further, only 34.3% of farmers accessed credit for farming. With Pseudo R2 value of 0.78, farm tenure system, fertilizer use, access to credit and access to extension services significantly influenced cocoa yield, while the age of cocoa farmer, age of farm trees and vulnerability of farm to natural disaster negatively affected cocoa yield. Tukey HSD results (p<0.00) indicate that rural banks credit allocations to non-agricultural activities such as trade and transport, and social loans had the highest percentage means which suggests that agriculture is treated less favorable in rural banks' credit portfolio. These findings give credence to the assertion that rural banks are deviating from their core mandate of supporting agriculture in Ghana.
Conclusion: This study reaffirms the supporting roles played by rural and community banks in increasing cocoa yield in Ghana. However, this research recommends that, the Bank of Ghana should closely monitor the activities of these unit banks to reduce the instances of diverting all their funds to non-agricultural related activities.

Published: April 2020

Background: Mentoring is key to a successful career in medicine. Mentoring is the goal of developing nurturing relationships between elder adult who is dependable and someone who is younger needs consistent support or an intervention. Mentoring has shown to be essential for the acquisition of clinical and research skills, as well as career development. A good mentor maintains sight of the overall goal of the relationship and hold the focus for mentees personnel and professional growth overtime.
Objectives: The objectives of study were to explore how faculties of medical and dental programme understand their role as mentors and to identify the perceptions of faculties regarding mentoring medical and dental students.
Methodology: Cross sectional study was conducted at Melaka Manipal Medical College and lecturers from medical and dental faculties were participated in the study. The data were analysed by using SPSS.
Results: There were total 48 faculties (38 medical and 10 dental faculties) participated in this study. Majority (39.58%) of faculties defined mentor as counsellor, (22.91%) career guide, (16.6%) role model while (8.3%) defined as research guide. Regarding perception of faculties on the mentorship program, (81.2%) of faculties perceived that mentors have positive influence on choosing future specialties options of the mentees, (75%) of the faculties were willing to discuss with the mentees regarding personal, financial issues as well as academic performance individually, (77%) perceived that time constraint is the barrier for successful programme and (62.5%) of faculties perceived that there should have a formal training prior to appointment as mentor.
Conclusion: It was concluded that the roles, tasks and communication of mentor and mentees should be standardized. Mentors should have a formal training prior to appoint as mentor.

Authors: Ajani Rotimi Sunday , Balogun Oluwafisayomi Tesleem 
Published: April 2020

Objective: The health hazards of tobacco smoking and diabetes mellitus constitute major and diverse global burden. The influence of Nicotiana tabacum (tobacco) powder and ethanolic extract on excised wound of diabetic rats was investigated.
Methods: The wounds of diabetic adult male wistar rats in groups of six were dressed with tobacco powder (TPD), tobacco ethanolic extract (TED), sofratulle (SD) and normal saline (ND) daily till healed. There were composite control groups namely TPC, TEC, SC and NC.
Every three days, the wound areas were measured in order to calculate the mean wound contraction rates. Granulation tissue was biopsied from an animal per group on day 3,6 and 9 for histopathological evaluation and after healing, the scars of the remaining animals were biopsied for histology.
Results: On day 3, the tobacco powder diabetic (TPD) group had the highest mean wound contraction rate and even higher than its control group. At day 18, the tobacco extract control group had the least mean wound contraction rate. The mean wound contraction rates of some diabetic groups were significantly higher than those of the respective control on day 3 and 12 (TPD vs TPC; TED vs TEC). The TPD mean wound contraction rates were significantly higher than those of ND on day 3,6,9 and 12. Histology of the granulation tissues of the tobacco diabetic groups was similar to those of the other groups. Sections of the wound scars revealed stratified squamous epithelia with abundant collagen fibres and blood vessels in all the groups. It was also observed that the scars were more fibrous than cellular with dermal appendages observed in some of the groups.
Conclusion: Topical application of Nicotiana tabacum (Tobacco) promotes wound healing with scars comparable to those of rats dressed with sofratulle.

AbstractAn electrochemical direct ortho‐hydroxylation of 2‐aryl‐4H‐benzo[e][1,3]oxazin‐4‐ones was developed with Pd(OAc)2 as catalyst, oxazine ring as a directing group and Oxone as the hydroxylation reagent. A series of hydroxylation products were obtained under mild conditions, and the yields were from medium to good. This method is characterized by good functional group tolerance and a wide range of substrates. More importantly, use anodic oxidation to avoid the use of potentially toxic and polluting oxidants. A gram‐scale direct electrochemical hydroxylation of 2‐phenyl‐4H‐benzo[e][1,3]oxazin‐4‐one was performed, and the hydroxylation product was applied to synthesize the drug deferasirox. In addition, the single crystal of 2‐(2‐hydroxyphenyl)‐4H‐benzo[e][1,3]oxazin‐4‐one was obtained and determined by X‐ray diffraction. Finally, the reaction mechanism was proposed and verified by cyclic voltammetry (CV). This protocol also provides an alternative electrochemical hydroxylation methodology for the functionalization of molecules.magnified image
Disparities between Antibody Occupancy, Orientation, and Cytotoxicity in Immunotherapy
Authors: Ta Angeline N. , Tennyson Rachel L. , Aceveda Diane C. , McNaughton Brian R. 
Published: April 2020

AbstractWe report fusion proteins designed to bind spatially distinct epitopes on the extracellular portion of HER2, a breast cancer biomarker and established therapeutic target, and recruit IgG (either anti‐His6 or serum IgG) to the cell surface. When the proteins were incubated with anti‐His6 antibody and various concentrations of a single HER2‐binding protein His6 fusion, we observed interference and a decrease in antibody recruitment at HER2‐binding protein concentrations exceeding ∼30 nM. In contrast, concomitant treatment with two or three distinct HER2‐binding protein His6 fusions, and anti‐His6, results in increased antibody recruitment, even at relatively high HER2‐binding protein concentration. In some instances, increased antibody recruitment leads to increased antibody‐dependent cellular cytotoxicity (ADCC) activity. While a fusion protein consisting of a HER2‐binding nanobody and Sac7d, a protein evolved to recognize the Fc domain of IgG, binds IgG from serum, antibody recruitment does not lead to ADCC activity. Rationales for these disparities are provided. Collectively, our findings have implications for the design of efficacious targeted immunotherapeutic biologics, and ensembles thereof.
Mg2+/F− Synergy to Enhance the Ionic Conductivity of Na3Zr2Si2PO12 Solid Electrolyte for Solid‐State Sodium Batteries

Published: April 2020

AbstractNa super ion conductor (NASICON) Na3Zr2Si2PO12 (NZSP) is considered to be one of the most promising solid electrolytes for solid‐state sodium batteries. However, low ionic conductivity is one of the main challenges for its practical application. Herein, we report a novel Mg2+/F− co‐assisting strategy to synthesize NZSP solid electrolyte with enhanced ionic conductivity. Mg2+/F‐ co‐assisting leads to a significant increase in the particle size and a reduction in the concentration of grain boundary. A dense microstructure is also formed with co‐assisting. Consequently, high ionic conductivity of 2.21 mS cm−1 at 300 K, low electronic conductivity of 1.76×10−5 mS cm−1 at 300 K and low activation energy of ∼0.27 eV are achieved for the optimized Mg2+/F− co‐assisted NZSP solid electrolyte. Finally, a Na/Na3V2(PO4)3 solid‐state sodium battery employing Mg2+/F− co‐assisted NZSP solid electrolyte exhibits an excellent electrochemical performance. High discharge specific capacity of 71.5 mAh g−1 is displayed at 1 C at 300 K, with 96 % retention after 100 cycles. Therefore, this cation/anion co‐assisting strategy provides inspiration for the development of other classes of ceramic solid electrolytes for solid‐state sodium batteries.

Published: April 2020

AbstractOne experiment was conducted from 2015 to 2016 on a Calloway and Dewitt silt loam soil near Pine Tree (pH 8.3) and Stuttgart (pH 6.0), Arkansas, respectively. The objective was to evaluate the potential for a benzobicyclon application to carryover from rice and cause damage to corn, cotton, grain sorghum, soybean, and sunflower planted the subsequent year. No injury or stand reduction occurred for any crop after applications of benzobicyclon at 0.22 and 0.44 lb a.i. acre−1 at either location. Grain sorghum had a 29% height reduction at Pine Tree at 12 d after planting (DAP); however, no differences in height occurred at Stuttgart, and by 40 DAP, all heights were similar between treated and nontreated plots at both locations. Plant height of corn, cotton, soybean, and sunflower was not reduced in treated plots. At Pine Tree, 53 and 56% reductions in corn yield resulted from benzobicyclon at 0.22 and 0.44 lb acre−1, respectively, whereas cotton, grain sorghum, and soybean yields were not affected by benzobicyclon residues. Yields of all crops at Stuttgart were not negatively affected by benzobicyclon application the previous year. This research shows that benzobicyclon applied to rice is unlikely to injure cotton and soybean or to have a negative impact on crop yield the in subsequent growing season.
Chiral Brønsted Acid Catalyzed Enantioconvergent Propargylic Substitution Reaction of Racemic Secondary Propargylic Alcohols with Thiols

Published: April 2020

AbstractDespite the significant progress of the enantioselective reaction using chiral catalysts, the enantioselective nucleophilic substitution reaction at the chiral sp3‐hybridized carbon atom of a racemic electrophile has not been largely explored. Herein, we report the enantioconvergent propargylic substitution reaction of racemic propargylic alcohols with thiols using chiral bis‐phosphoric acid as the chiral Brønsted acid catalyst. The substitution products were formed in high yields with high enantioselectivities in most cases. The cation‐stabilizing effect of the sulfur functional group introduced at the alkynyl terminus is the key to achieving the efficient enantioconvergent process, in which chiral information originating from not only the racemic stereogenic center but also the formed contact ion pair is completely eliminated from the present system.
