This study examined the relationship between the adoption of bio-fortified provitamin- A cassava varieties and farming households’ health outcomes using cross sectional data obtained from 318 cassava farmers in southeast Nigeria. The data was analysed using binary logistic regression, propensity score matching of treatment effects and percentages. The study found that number of children under five, household size, education of head of household, extension service, ownership of television, radio, mobile phone and tricycle, membership of cooperative societies, and access to credit were the significant predictors of adoption of pro-vitamin-A bio-fortified cassava varieties in the States. The study also found that the main constraints militating against adoption of pro-vitamin-A bio-fortified cassava include decaying of roots immediately after maturation,high cost of cassava stem, and high moisture content. The estimate of the effect of the adoption of bio-fortified pro-vitamin-A cassava varieties onincidence of vitamin-A deficiency related diseases was significant with an average treatment effect on the adopters of -0.463. The adoption of bio- fortified pro-vitamin-A cassava varieties has substantial effect on the reduction of vitamin-A deficiency related health outcomes. There is need for wider awareness and dissemination of the varieties among cassava farmers, while interventions should target the promotion of both production and consumption of such cassava varieties.
Key words: adoption of bio-fortified cassava varieties; vitamin A deficiency related diseases

Published: October 2020

The study assessed the factors influencing the involvement of youths in poultry production in Abia State, Nigeria. Specifically, the study assessed the extent of youth’s involvement in poultry production; and ascertained the perceived factors that influence the involvement of youths in poultry production. Multistage sampling procedure was employed in selecting 120 young poultry farmers. Data collected were analyzed using percentage, and mean, as well as ordinary least square regression analysis. Results revealed that the youths in the study area participated moderately in poultry production and the foremost poultry production activities being participated by the youths included feeding ( x̄ = 2.81), packing and replacement of litters ( x̄ = 2.59), and vaccination/medication ( x̄ = 2.54). Moreover, the perceived factors influencing the youths’ involvement in poultry production were income ( = 3.69), cost of feed ( = 3.45), and availability of land ( x̄ = 3.33). The coefficients of age (0.013), membership to co-operative (0.042), years of experience (0.016), and extension contact (0.015) were positive and significantly influenced the involvement of the youths in poultry production. Enabling youths’ access to credits, subsidizing the cost of feed, and organizing training for the youths on poultry production were recommended.

CADERNOS NEGROS E AMERICANAH: CABELOS CRESPOS, AFIRMAÇÃO IDENTITÁRIA E OUTROS ANSEIOS
Authors: Oliveira Bárbara Maria de Jesus , Oliveira Maria Anória J. 
Published: October 2020

O objetivo do presente texto é refletir sobre o processo de negação e/ou afirmação identitária das protagonistas em Impressões de uma infância (Cadernos Negros, no 36), de autoria de Silvana Martins (2013) e no romance Americanah, de Chimamanda Adichie (2014), a partir da relação com os seus cabelos crespos. Para tanto, realizamos a pesquisa bibliográfica e nos norteamos em estudos oriundos da literatura em interface com outras áreas do conhecimento. Com base nos estudos de Cuti, Florentina Souza, Jailma Moreira, Ana Rita Santiago e Eduardo Duarte, situamos a noção de literatura negra/afro-brasileira e destacamos a relevância das abordagens que visibilizam as vozes/linguagens das margens (HALL, 2005; hooks, 2019). Dentre estas, as referidas obras e respectivas fundamentações. À guisa da conclusão, refletimos acerca do impacto do padrão estético brancocêntrico (cabelos lisos ou alisados) para a re/constituição identitária das protagonistas culminando-se, por fim, com a “autorrecuperação” (hooks, 2019) e, por conseguinte, a reexistência.

UMA LEITURA SOCIOLÓGICA DE “ANA DAVENGA”, DE CONCEIÇÃO EVARISTO
Authors: Araújo Leticia da Rocha de , Sá Michele Eduarda Brasil de 
Published: October 2020

O presente trabalho tem como foco realizar uma leitura sociológica do conto “Ana Davenga”, de Conceição Evaristo, publicado no livro Olhos d’água em 2014, apresentando reflexões preliminares a respeito da condição da mulher negra tal como retratada no conto. Parte-se da concepção da literatura como instrumento de humanização: abordar a literatura afro-brasileira contribui não só para o conhecimento da sociedade brasileira, mas também minimiza preconceitos contra o povo negro. A análise conduzida apoia-se ainda em um recorte interdisciplinar com a sociologia, tangenciando com os estudos feministas (especialmente o feminismo negro), na medida em que considera a mulher negra como alvo de duplo preconceito. Apesar da narrativa contundente de Evaristo e do trágico desfecho, o conto se encerra com uma imagem de alento em meio ao sofrimento e à desigualdade. Como resultados esperados, temos a reflexão sobre o papel da literatura afro-brasileira no combate ao preconceito racial e a interpretação de um personagem emblemático que representa a condição da mulher negra e pobre no Brasil.

Published: October 2020

Abstract. The purpose of this work is to study the subsoil structure of the Campi Flegrei area using both spectral ratios and array techniques applied to seismic noise. We have estimated the dispersion curves of Rayleigh waves by applying the Frequency–Wavenumber (f–k hereinafter) and Modified Spatial Autocorrelation (MSPAC) techniques to the seismic noise recorded by the underground short period seismic Array “ARF”, by the broadband stations of the UNREST experiment and by the broadband stations of the seismic monitoring network of INGV – Osservatorio Vesuviano. We have performed the inversion of a dispersion curve (obtained averaging the f–k and MSPAC dispersion curves of seismic noise and single phase velocity values of coherent transient signals) jointly with the H∕V spectral ratio of the broadband station CELG, to obtain a shear wave velocity model up to 2000 m depth. The best-fit model obtained is in a good agreement with the stratigraphic information available in the area coming from shallow boreholes and deep wells drilled for geothermal exploration. In active volcanic areas, such as Campi Flegrei, the definition of the velocity model is a crucial issue to characterize the physical parameters of the medium. Generally, a high quality characterization of the medium properties helps to separate the contributions of the volcanic source, path and site in the geophysical observables. Therefore, monitoring possible variations in time of such properties in general can help to recognize anomalies due to the volcano dynamics, i.e. fluid migration connected to the volcanic activity.
John Maynard Keynes, cuantitativista renegado
Authors: Méndez Ibisate Fernando 
Published: October 2020

El giro radical dado por John Maynard Keynes en su Teoría General de 1936 tuvo raíces en su teoría y política monetarias que, más que un proceso evolutivo, resultó un abandono completo de la teoría cuantitativa monetaria, sobre la que había asentado sus obras previas, y la renuncia al objetivo de estabilidad de precios y la política monetaria como instrumento para encauzar las perturbaciones de la actividad y desempleo de recursos. En la Teoría General, Keynes centra el problema en el sistema económico de mercado, que produce tales resultados desastrosos de forma inherente y persistente.
El trabajo explica este cambio teórico radical, analizando su contenido o fondo y sus posibles razones, cuya catálisis establezco en los acontecimientos de 1925.
Eudaimon in the Rough: Perfecting Rand’s Egoism
Authors: Bissell Roger E. 
Published: October 2020

Abstract
The author argues that Rand’s ethical theory is much closer in essence to the eudaimonist, self-perfectionist perspectives of Aristotle and the neo-Aristotelians, Douglas Den Uyl and Douglas Rasmussen, than to the “selfish,” egoistic ethics many assume to be her basic position. He discusses Rand’s anti-hedonist and pro-rational selfishness positions as corollaries of man’s life as the standard of moral value, as well as Rand’s point that treating either happiness or personal benefit as the standard of moral value is a reversal of cause and effect. He also identifies the oppressive negativism in Rand’s discussion of the seven canonical Objectivist virtues.
Bondades y Limitaciones de la Operacionalización de Objetivos en los Programas Educativos o de Intervención Social: un Ejemplo al Interior de la Psicología Educacional.
Authors: López Ulloa Susana 
Published: October 2020

Se investigó el comportamiento de la variable “nivel de especificidad en la redacción de objetivos educacionales de socialización”. El análisis de los datos recopilados por tres entrevistas aplicadas a 51 educadores revelaron coeficientes de correlación que, aunque moderados, son estadísticamente significativos e indican que los profesores tienden a redactar objetivos de mayor nivel de especificidad mientras menor sea la edad de sus alumnos, el nivel de escolaridad y el numero de alumnos de su curso. Por otra parte, el nivel de especificidad alcanzado por los profesores en la redacción de sus objetivos educativos está positivamente correlacionado con una experiencia exitosa de aplicación de técnicas conductuales en el salón de actividades. Finalmente, ni el número de cursos en los cuales los educadores han recibido instrucción respecto a condicionamiento operante, ni la utilidad que los profesores le atribuyen a estas técnicas mostraron una correlación estadísticamente significativa con el nivel de especificidad de los objetivos que redactaron. El estudio concluye analizando la necesaria complementariedadde la relación entre lo general y lo específico.
La Psicopatología Evolutiva y los Factores de Riesgo y Protección: el Desarrollo de una Mirada Procesual
Authors: Cova Solar Félix 
Published: October 2020

La psicopatología evolutiva es considerada actualmente el paradigma dominantede la investigación psicopatológica. El desarrollo de esta disciplina ha tenido unimpacto importante en la investigación de los factores de riesgo de trastornos mentales, obligando a generar enfoques más procesuales que presten atención no sólo a la identificación de estos factores sino a comprender sus modos de actuar. Este artículo analiza algunos de los desafíos que enfrenta hoy la investigación en psicopatología evolutiva y presenta dos modelos que tratan de lograr una comprensión más procesual de los determinantes psicosociales de la psicopatología infanto-juvenil.
A rare cutaneous lesion in the neonatal period: The non-Langerhans cell histiocytosis
Authors: BARUTCU Adnan , OZLU Ferda , YAPICIOGLU YILDIZDAS Hacer , SATAR Mehmet 
Published: October 2020

The non-Langerhans cell histiocytosis (non-LCH) is a group of diseases characterized by cutaneous involvement in the neonatal
period. The non-LCH affects less than 1 in 200,000 children born each year. A definitive diagnosis is important for the treatment of
the disease. Therefore, skin biopsies should be performed in neonates with cutaneous lesions as early as possible. Only in the presence
of cutaneous involvement without systemic involvement, it does not require any treatment, because the lesions can mostly self-heal.
Here, we present a neonate diagnosed with non-LCH following a skin biopsy.

Étude qualitative descriptive sur l’expérience des patients avec réactions cutanées induites par la radiothérapie pour un cancer de la tête et du cou
Authors: McQuestion Maurene , Cashell Angela 
Published: October 2020

La majorité des patients recevant de la radiothérapie auront une réaction cutanée radio-induite allant d’un érythème léger à une desquamation humide étendue. Les réactions cutanées attendues varieront en fonction du diagnostic de cancer, de la dose et de la taille du champ d’irradiation ainsi que d’autres facteurs liés au traitement et au patient. Récemment, la recherche a dissipé les mythes longtemps entretenus sur les produits pour le soin de la peau qui auraient été à éviter avant le traitement, tout comme le déodorant et l’antisudorifique durant les traitements contre le cancer du sein (on craignait une surdose accrue pour la peau causée par l’utilisation de ces produits). Cette limitation a été levée. Or, la plupart des recherches sur les réactions cutanées radio-induites ont été menées auprès de femmes atteintes d’un cancer du sein; aucune n’a été trouvée sur les patients atteints de cancer de la tête et du cou, alors que de tous les groupes de patients, ce sont très souvent ceux-ci qui présentent les réactions cutanées les plus graves. Nous avons fait appel à la méthode descriptive interprétative qualitative basée sur le travail méthodologique de Thorne (1997) pour interroger neuf participants sur leurs réactions cutanées par suite de radiations pour leur cancer de la tête et du cou. Trois thèmes sont ressortis des entretiens : 1) l’expérience des symptômes; 2) la comparaison avec d’autres; 3) l’expérience du soutien et de l’information. Les implications comprennent des recommandations pour la pratique et l’éducation des patients.
Triple-Positive Breast Carcinoma: Histopathologic Features and Response to Neoadjuvant Chemotherapy
Authors: Zeng Jennifer , Edelweiss Marcia , Ross Dara S. , Xu Bin , Moo Tracy-Ann , Brogi Edi , D'Alfonso Timothy M. 
Published: October 2020

Context.—
It is unclear whether HER2+ tumors expressing both estrogen receptor (ER) and progesterone receptor (PR), that is, triple-positive breast carcinomas (TPBCs), show unique morphologic and clinical features and response to neoadjuvant chemotherapy (NAC).

Objective.—
To study the morphologic and immunohistochemical features of TPBCs from patients who underwent NAC.

Design.—
We retrospectively reviewed core biopsy and post-NAC slides of 85 TPBCs. H-scores were calculated for ER and PR. HER2 slides and fluorescence in situ hybridization (FISH) reports were reviewed. Residual cancer burden was calculated for post-NAC specimens.

Results.—
Eighty-one of the 85 tumors (95.3%) showed ductal histology, 3 (3.5%) were invasive lobular carcinomas, and 1 (1.2%) showed mixed ductal and lobular features. A subset showed mucinous (n = 7, 8.2%), apocrine (n = 5, 5.9%), and/or micropapillary (n = 4, 4.7%) differentiation. Fifty-four TPBCs (63.5%) showed high ER expression (H-score &gt;200), including 27 (31.8%) with high expression of ER and PR. Fifty-two tumors (61.1%) showed HER2 3+ staining. Mean HER2/CEP17 ratio by FISH was 3.6 (range, 2–12.2) and mean HER2 signals per cell was 8 (range, 3.7–30.4). Pathologic complete response (pCR) rate was 35.3% (30 of 85). HER2 3+ staining was the only significant predictor of pCR on multivariate analysis (odds ratio = 9.215; 95% CI, 2.401–35.371; P &lt; .001). The ER/PR expression did not correlate with response to therapy.

Conclusions.—
TPBCs are heterogeneous with some showing mucinous, lobular, or micropapillary differentiation. The pCR rate of TPBCs is similar to that reported for ER+/PR−/HER2+ tumors. HER2 overexpression by IHC was associated with significantly better response to therapy and may help select patients for treatment in the neoadjuvant setting.
Copper Ferrite Superparamagnetic Nanoparticle-Catalyzed Cross-coupling Reaction to Form Diindolylmethane (DIM): Effect of Experimental Parameters
Authors: Nguyen Oanh T.K. , Pha Ha Trong , Khoa Huynh Dang , Nguyen Duy Chinh , Tam Nguyen Thi Hong 
Published: October 2020

Superparamagnetic copper ferrite (CuFe2O4) nanoparticles were utilized as a heterogenous catalyst for the cross-coupling reaction of indole to form 3,3’-diindolylmethane (DIM) as the desirable product. High reaction yield, at around 82%, was achieved under optimal conditions. The CuFe2O4 material could be easily separated from the reaction mixture by an external magnetic field and could be reutilized several times without a significant decrease in catalytic activity. We also showed that no sites of catalyst material leached into reaction solution was detected. To our best knowledge, the above cross-coupling reaction was not previously conducted under catalysis of superparamagnetic nanoparticles. Copyright © 2021 by Authors, Published by BCREC Group.

Study of the Interaction of Heavy Metals (Cu(II), Zn(II)) Ions with a Clay Soil of the Region of Naima-Tiaret-Algeria
Authors: Mohamed Taibi , Abdelkader Elaziouti , Nadjia Laouedj , Abdelkader Dellal 
Published: October 2020

The RM (RM stands for the pristine clay) collected from sites in the Naima-Tiaret-Algeria and its purified phase TM (TM stands for the treated clay) were characterized using XRF, XRD, FT−IR, SEM−EDX, and DC electrical conductivity techniques. The as-prepared clays were used as potential adsorbents for the removal of Cu2+ and Zn2+ metals ions. Highly purified clay TM, exhibiting a basal, spacing of 25.83 Å and CEC of 51 meq/100 g, was obtained. The type of interstratified I/M in the studied sites is S=1, based on the calculation method of Watanabe. The percentage of illite type S=1 is between 80−85% illite. The adsorption equilibrium was established in 60 min with the capacities of 28.57 and 24.39 mg/g for Cu2+ onto RM, 32.25 and 4.95 mg/g for Zn2+ in the presence of TM. D-R isotherm model was more suitable with the adsorption process than Freundlich and Langmuir models suggesting the ion exchange nature of the retention mechanism in most cases (E > 8 kJ/mol). Pseudo second-order model best described the kinetics of adsorption process. The adsorption mechanism was mainly monitored by ion exchange mechanism between exchangeable interlayer cations (Na) in the interstratified I/M and Cu2+ or Zn2+ metals from aqueous matrix. Further, the release of H+ ions from the edge of the layer structure in acidic environments promote the adsorption of heavy metals onto the surfaces interstratified I/M clay soils via electrostatic attraction.

Published: July 2002

AbstractObjectives: Polycystic ovary syndrome (PCOS) presents a high risk of developing type 2 diabetes mellitus. We studied a group of women with PCOS and evaluated this defect in insulin action. Methods: The study population consisted of nine PCOS women, six obese type 2 diabetic patients, and five controls whose body mass index (BMI) was similar to that of the nine PCOS women. The 75‐g oral glucose tolerance test (OGTT) and the hyperinsulinemic euglycemic glucose clamp test were performed. Clinical characteristics and the metabolic profiles, including the insulin sensitivity index (ISI), were compared. Results: PCOS women showed significantly elevated insulin responses during OGTT, but their blood glucose levels were comparable with the controls. The subjects with PCOS had more insulin resistance than the other groups. There was no difference among the groups in terms of clinical characteristics and metabolic profiles, except age, luteinzing hormone (LH), testosterone, and sex hormone binding globulin (SHBG). Conclusion: We conclude that PCOS women have significant insulin resistance which is independent of adiposity.
Single dose methotrexate therapy: application to interstitial ectopic pregnancy
Authors: Borgatta L , Burnhill M , Stubblefield P 
Published: July 2002

AbstractA woman with a small (6‐mm gestational sac) interstitial pregnancy had complete resolution after medical therapy alone. A single cycle of methotrexate 50 mg/m2 was used as outpatient treatment without any operative procedure either for diagnosis or intervention. The guidelines that have evolved for selection of women for single dose methotrexate treatment for both intrauterine and tubal ectopic pregnancies may be applicable to interstitial ectopic pregnancy as well. A suggested framework for treatment decisions is presented.
Medical ethics and the judicial coerced treatment of sexual abusers
Authors: Cosyns P 
Published: July 2002

SummaryThe increasing demand for judicial coerced treatment of sexual abusers constitutes a new challenge for mental health professionals. The discussed controversial ethical issues are the influence of coercion on the treatment, the motivation of patient as well as therapist, confidentiality and hormonal treatment. Social control is not the primary concern of therapists and any treatment must be beneficial to the individual patient. The coerced treatment of sexual abusers requests an agreement between psychiatric and judicial authorities with respect for their respective professional ethics.
