Background

Extended-spectrum beta-lactamase (ESBL) producing bacteria present an ever-growing burden in the hospital and community settings. Data on the prevalence of ESBL fecal carriage remain scarce in Ethiopia. Therefore, this study aimed to determine the prevalence of ESBL producingEscherichia coliandKlebsiella pneumoniaefecal carriage among children under five years in Addis Ababa, Ethiopia.

Methods

A facility-based cross-sectional study was conducted from April to May 2017. A total of 269 fecal/rectal swab samples were cultured on MacConkey agar. All positive cultures were characterized by colony morphology, Gram stain, and standard biochemical tests. Further, bacteria identification, antimicrobial susceptibility testing, and phenotypic detection of ESBL production were performed using VITEK 2 Compact as per the instruction of the manufacturer. Socio-demographic and risk factors data were collected using questionnaires. Data were entered by EPI INFO version 7.2.1.0 and analyzed by SPSS version 20.

Results

The overall prevalence of ESBL-producingE.coliandK.pneumoniaewas 17.1% (46/269; 95% CI: 12.9%–22.7%). A total of 47 isolates were ESBL-positive, of which, 83.0% wereE.coliand 17.0% wereK.pneumoniae. ESBL producingE.coliandK.pneumoniaeisolates were also showed high levels of MDR (93.6%) and high rates of co-resistance to aminoglycosides, fluoroquinolones, and trimethoprim-sulfamethoxazole. However, all isolates were carbapenem susceptible. In the risk factors analysis, Children’s mothers who had lower educational level (primary school) (OR: 2.472, 95% CI: 1.323–4.618, P = 0.0062) and children who used tap water for drinking (OR: 1.714, 95% CI: 1.001–3.659, P = 0.048) were found to be significantly associated with higher ESBL fecal carriage.

Conclusions

In this study, the high prevalence rate of ESBL producingE.coliandK.pneumoniaefecal carriage and high level of multidrug resistance among ESBL producingE.coliandK.pneumoniaewere demonstrated. This suggested that the necessity of routine screening of ESBL is crucial for the early detection and appropriate antibiotics selection for infection caused by ESBL producing pathogens.

Introduction

PDL1 and its interaction with PD1 is implicated in immune dysfunction in TB and HIV. The expression of PDL1 on multiple subsets of monocytes as well as their associations with cytokines and microbial products have not been well studied.

Method

HIV (TB-HIV+), TB (TB+HIV-) and TB/HIV co-infected (TB+HIV+) patients as well as apparently healthy controls (TB-HIV-) were recruited. TB and HIV patients were treatment naïve while TB/HIV patients were both ART naïve and experienced but not yet started TB therapy. Monocyte subsets were evaluated for PDL1 expression by flow cytometry; plasma TNFα, IL6, IP10, IFNγ and IL10 were measured by Luminex; and cytokine mRNA from purified monocytes quantitated by qPCR. The association of PDL1 with cytokines, clinical and microbial indices, including HIV viral load, TB smear microscopy and TB urinary lipoarabinomannan (LAM) were assessed.

Results

Monocyte expression of PDL1 was significantly higher in TB, HIV and TB/HIV co-infected patients compared with healthy controls (p = 0.0001), with the highest levels in TB/HIV co-infected patients. The highest expression of PDL1 was on intermediate (CD14+CD16+) monocytes in all participant groups. PDL1 strongly correlated with HIV viral load in TB/HIV while weakly correlated in HIV. PDL1 levels moderately correlated with plasma TNFα, IL6, IP10, IFNγ and IL10 level in TB subjects whereas weakly correlated with TNFα and IP10 in HIV patients. However, cytokine mRNA from purified monocytes showed no association with either plasma cytokines or monocyte PDL1 expression, implying that if cytokines modulate PDL1, they are likely not originating from circulating monocytes themselves. These results underscore the importance of further characterization of multiple monocyte subsets and their phenotypic and functional differences in different disease states.

Published: October 2021

The study aimed at a quantitative evaluation of macular vasculature after primary repair of rhegmatogenous retinal detachment (RRD) in correlation with the elapsed postoperative time. Optical coherence tomography angiography (OCT-A) was performed in 66 eyes of 33 patients in a retrospective case-control study: superficial and deep retinal vessel density (VD) of the whole image, fovea, parafovea, non-flow area, and foveal avascular zone (FAZ) were measured. Data of eyes with RRD were compared to the healthy fellow eyes in 3 groups according to the elapsed time after surgery: RD1: 6–12 months (n = 10), RD2: 1–2 years (n = 10), and RD3: 2–10 years (n = 13). In RD1 VD was significantly lower in the superficial parafoveal, deep parafoveal, and deep whole area compared to the fellow eyes. In RD3 VD was significantly lower in the superficial fovea, parafovea, whole image, and deep fovea, the non-flow area was significantly enlarged. OCT-A demonstrated a significant reduction in the superficial and deep regions of the macular vasculature after the repair of RRD. The deep area is more affected in the early postoperative period and the superficial region and the extent of the non-flow area are more involved after a longer postoperative time.
The availability of psychological support following road travel injuries in Namibia: A qualitative study
Authors: Chatukuta Mitchel , Groce Nora , Mindell Jenny , Kett Maria
Published: October 2021

Road traffic injuries (RTIs) are a major problem worldwide with a high burden of mental health problems and the importance of psychological support following road injury is well documented. However, globally there has been very little research on the accessibility of psychological services following road injury. Namibia is one of the countries most affected by RTIs but no previous studies have been done on this. In this qualitative study we investigated the availability of psychological services to RTI injured in Namibia. Our study findings are in line with those of other global studies in showing inadequate access to psychological support for injury survivors and we discuss the reasons. It is hoped these findings will help policymakers develop ways of enhancing access to psychological support for the many people injured in RTIs in Namibia. The models they develop may also be of use to other LMICs countries with high RTI rates.
La conflictividad obrera en la empresa textil asturiana Obrerol (1979-2009): la división sexual e internacional del trabajo
Authors: González de Arriba Nerea
Published: October 2021

Narramos la conflictividad laboral protagonizada por la plantilla de la empresa textil gijonesa Obrerol, a partir de las entrevistas a las propias trabajadoras, y a la labor de investigación en hemerotecas y archivos. Reivindicaciones, huelgas y pleitos encabezados por mujeres contra la patronal textil asturiana y que tratamos rescatar del olvido de la memoria sindical. Concretamente en 1984 tuvo lugar su huelga más cruenta, en cuyo trasfondo residía la denuncia a la externalización de la producción intrínseca al sector. Lo que nos lleva a visualizar y a relacionar la conflictividad obrera de un estudio de caso particular con los procesos globalizados capitalistas de deslocalización de la producción y la acentuación de la división sexual e internacional del trabajo.
El tiempo de Madariaga y la idea de Europa: Salvador de Madariaga en el Congreso de Europa en La Haya (1948)
Authors: Gavín Munté Víctor
Published: October 2021

La idea de Europa en Salvador de Madariaga se fundamentaba en el convencimiento que, sin la creación previa de una conciencia europea, entendida como la capacidad de pensar los problemas de Europa sin tomar en cuenta las fronteras que dividen a los diferentes estados que la conforman, cualquier proyecto de integración política o económica estaría incompleto. La solidaridad de hecho, es decir, aquella derivada de las inevitables interrelaciones político – económicas entre los estados, debería completarse con la solidaridad subjetiva que une a las personas más allá de los intereses materiales, convirtiendo así sus problemas en comunes sólo solucionables con planes también comunes. Ello sería posible con la existencia de una conciencia europea que debería ser asumida por una élite encargada de dotar de ‘alma europea’ a las instituciones que se crearan. Esta idea la defenderá Salvador de Madariaga en el Congreso de Europa en La Haya (1948) y tendrá su plasmación práctica en el Colegio de Europa en Brujas (1949) fundado a iniciativa suya y al cual estará vinculado como presidente de su Consejo de Administración hasta el año 1972. Un año después recibiría el Premio Carlomagno por su labor en favor de la construcción de Europa.
Estrategias de comunicación y de intervención frente a desastres en la Monarquía Hispánica bajo Carlos II
Authors: Cecere Domenico
Published: October 2021

Este estudio reconstruye la circulación de información entre diferentes territorios de la Monarquía Hispánica sobre dos calamidades ocurridas a fines del siglo XVII: el terremoto de Lima de 1687 y el terremoto de Sannio de 1688. En el centro del análisis se sitúa la transmisión de noticias y opiniones, tanto dentro de los órganos de gobierno, como en el ámbito más amplio de la comunicación externa de los circuitos institucionales. Se analizan las formas en que las informaciones sobre los dos eventos se sometieron a un proceso de reelaboración y se fijaron en un esquema interpretativo único, cargándose de significados morales, políticos, religiosos. Esta reconstrucción permite, por un lado, observar las diferentes fases de los procesos de elaboración de eventos traumáticos colectivos, mientras que, por el otro, pone en evidencia los mecanismos de recogida y difusión de la información, que muchas veces conectaban entre sí los grandes centros urbanos de la Monarquía, más allá del esquema centro-periferia.
Factores climáticos de las variaciones históricas de los precios de los cereales en el Nordeste de la península Ibérica en el siglo XVII.

Published: October 2021

El siglo XVII conoció en España varios periodos de crisis agrarias que provocaron escasez de productos de primera necesidad y un aumento del precio de los cereales. Las fluctuaciones de los precios del trigo, cebada y centeno están relativamente bien documentadas en muchas zonas del país; sin embargo, el conocimiento de la influencia que sobre estas variaciones pudieron tener factores climáticos y ambientales es aún muy limitado. En este trabajo se presentan los registros históricos del coste de los cereales de cuatro ciudades de diferentes entornos geográficos del Nordeste de la península Ibérica durante el periodo 1630-1660 y se comparan con los índices de sequía reconstruidos a partir de fuentes proxy documentales y dendroclimáticas. Se observa que las variaciones de los precios coinciden con anomalías regionales en la sequía de primavera-verano. Las correlaciones directas entre ambos son bajas, apenas superan r = 0,19; sin embargo, si el análisis se centra en los valores extremos, la influencia del clima aumenta: los precios son altos durante los periodos más secos y descienden durante los periodos considerados normales o húmedos; aunque con respuestas espacialmente variables. Esta correspondencia es mayor en los años anteriores y posteriores a la Guerra dels Segadors, lo cual indica que el intercambio de bienes y la coherencia de los datos estaban controlados tanto por factores sociopolíticos como ambientales, siendo estos últimos más influyentes en tiempos de paz.

Gênero e valores morais: uma análise na adesão de meninas e meninos aos valores da justiça e da solidariedade
Authors: Fanis Eduardo , Bicudo Bomfim Sanderli Aparecida
Published: October 2021

Nosso artigo relaciona-se à diferença na adesão aos valores justiça e generosidade pelos gêneros masculino e feminino. O objetivo foi verificar qual dos dois gêneros apresenta a adesão mais evoluída a cada um dos valores pesquisados. Utilizamos para isso dados de uma pesquisa que investigou alunos e alunas de 11 a 14 anos, por meio de situações hipotéticas. Por vivermos em uma sociedade sexista e isso afetar diretamente a educação das crianças, nossa hipótese foi que os meninos apresentariam um percentual maior na adesão à justiça, e as meninas apresentariam percentual maior quanto ao valor solidariedade, mas isso não se confirmou. Nossos resultados apontaram que as meninas apresentaram percentuais maiores de adesão a ambos valores.

Jogar como prática para favorecer a cooperação e o desenvolvimento moral
Authors: Ghisalberti Lucia
Published: October 2021

Para a abordagem psicogenética piagetiana, a consciência e a prática das regras são fundamentais para o desenvolvimento moral. Os contextos que envolvem o jogar com regras possibilitam a construção do conhecimento e estimulam interações cooperativas, auxiliando na superação do egocentrismo moral e intelectual, indispensável à construção de juízos morais autônomos. Os jogos de tabuleiro estimulam habilidades lúdicas, intelectuais e socioculturais. Esta pesquisa tem o objetivo de fazer uma análise bibliográfica de estudos que utilizaram jogos de tabuleiro na prática escolar, favorecendo a cooperação, a coordenação de perspectivas, a descentração e a autorregulação, fundamentais para a aprendizagem de regras e o desenvolvimento moral.
A concepção de H. Daly sobre o desenvolvimento sem crescimento em Marx nos tempos de pandemia
Authors: De Mello Liodoro
Published: October 2021

Desde meados do século XIX, a palavra progresso assumiu a forma de pensar e agir economicamente da sociedade contemporânea. Era o início da Revolução Industrial. O pensamento positivista, cujo principal mentor teria sido o sociólogo e filósofo francês Augusto Comte, perpassa por essa postura. O progresso foi considerado a principal forma de desenvolvimento, regendo o mundo capitalista e também moldando parte das políticas dos países que adotaram o socialismo real. Para ilustrar esse tema são apresentadas partes das teses de Herman Edward Daly, crescimento sem desenvolvimento, e de Karl Heinrich Marx, crescimento com equidade social fora do capitalismo.

Published: October 2021

Fundado em 1968 em Buenos Aires, o Colégio Aletheia desde seu início esteve sempre vinculado à vanguarda educacional. Aqueles eram tempos de agitação na Europa, de manifestações contra a Guerra do Vietnã nos Estados Unidos, de florescimento da contracultura e, na América Latina, de radicalização política e supressão da democracia. Ano de AI-5 no Brasil, que decretou o fim das liberdades individuais. Mas a Argentina ainda respirava ares de tumulto e liberdade naquele fim de década em que Maria Victoria Alfieri trabalhava em seu primeiro emprego, no equivalente naquele país ao jardim da infância. E foi ali que a jovem estudante de medicina, que havia iniciado um curso pensando em cuidar da saúde das crianças como pediatra, descobriu sua verdadeira vocação: cuidar de crianças, sim, mas como professora. Em especial, sua atenção se dirigiu às crianças pequenas.

Published: October 2021

Este trabalho discute resultados de atividades lúdicomatemáticas provenientes da realização de uma oficina pedagógica com jogos educativos com mulheres idosas frequentadoras de um Grupo de Convivência Clube de Mães (Campina Grande-PB). A proposta é baseada em reivindicações próprias evidenciadas ao participarem de ações socioeducativas desenvolvidas no Projeto de Extensão “Práticas de letramentos de pessoas idosas no cotidiano: traçando letras, esculpindo textos” (UEPB-PB), como o uso da Matemática para estimular a memória. Pretende-se suscitar reflexões sobre a questão: Os jogos matemáticos (“Jogo da velha”, “Caça números”, “Hexágono mágico” e “Corrida aos trinta”) estimulam as funções cognitivas das participantes? Essa discussão funda-se nas contribuições da Educação Gerontológica (KACHAR, 2001; CACHIONI, 2003) e da Educação Inclusiva (CARVALHO, 2004), ao considerar saberes da Matemática que, usado em jogos, estimulam a memória e compartilham aprendizagens. A discussão norteia-se pela abordagem qualitativa interpretativa ao analisar a participação lúdica das idosas quanto ao desempenho individual e avaliação coletiva. Os encontros revelaram expectativas em relação ao exercício da memória, com atividades lúdico-matemáticas e a reelaboração de saberes matemáticos compartilhados na interação.

Portal vein thrombosis (PVT) is a common complication in liver cirrhosis, especially in advanced cirrhosis. It may be related to a higher risk of liver-related events and liver function deterioration. Imaging examinations can not only provide an accurate diagnosis of PVT, such as the extent of thrombus involvement and the degree of lumen occupied, but also identify the nature of thrombus (i.e., benign/malignant and acute/chronic). Evolution of PVT, mainly including development, recanalization, progression, stability, and recurrence, could also be assessed based on the imaging examinations. This article briefly reviews the pathophysiology, diagnosis, classification, and evolution of PVT with an emphasis on their computed tomography imaging features.

A single server Markovian queuing system with limited buffer and reverse balking
Authors: Saikia Girin , Choudhury Amit
Published: October 2021

The phenomena are balking can be said to have been observed when a customer who has arrived into queuing system decides not to join it. Reverse balking is a particular type of balking wherein the probability that a customer will balk goes down as the system size goes up and vice versa. Such behavior can be observed in investment firms (insurance company, Mutual Fund Company, banks etc.). As the number of customers in the firm goes up, it creates trust among potential investors. Fewer customers would like to balk as the number of customers goes up. In this paper, we develop an M/M/1/k queuing system with reverse balking. The steady-state probabilities of the model are obtained and closed forms of expression of a number of performance measures are derived.

A paraszti önigazgatás középkori eredete és rétegei
Authors: Kurucz Ildikó
Published: October 2021

The peasant society had special autonomy from the Middle Ages. The local communities elected their own leaders, coordinated the common agricultural works of the land community, they judged on their own. Some characteristic attributes of these early autonomy survived the historical, political and social changes and remained dominant in the long run. In my study I present the genesis of the Hungarian villages and communities, the different components and layers of the traditional self-government. These questions are inseparable from the development of serfdom and its current situation. I point to the dichotomy inside of the communities, which stemmed from the property difference of the peasant society and from the conflicts of the individual and collective interests, which ones remained dominant till the end of 20. century.

Furuhashi, Y, Hioki, Y, Yoshimoto, S, and Hayashi, R. The effect of neutral, internal, and external focus on drop jump performance: is drop jump performance affected by plyometric training experience? J Strength Cond XX(X): 000–000, 2021—Providing an external focus of attention through verbal instructions can improve the drop jump (DJ) performance, which differs based on the skill level of athletes. The purpose of this study was to assess the effect of change of focus of attention on the performance of DJs in experienced and inexperienced athletes. Thirty-eight male collegiate athletes divided into the experienced group (E group: age, 21.5 ± 1.4 years; height, 173.4 ± 5.7 cm; and body mass, 65.7 ± 6.2 kg) and the inexperienced group (I group: age, 21.9 ± 1.5 years; height, 172.8 ± 5.1 cm; and body mass, 68.7 ± 5.5 kg) performed 2 trials of DJs after listening to instructions designed to evoke a neutral, internal, or external focus of attention. Contact time (CT), jump height (JH), reactive strength index (RSI), and leg-spring stiffness (kvert) were recorded during DJ and compared between the 2 groups using a repeated-measures analysis of variance. In the E group, the neutral condition was associated with a significantly higher RSI, JH, and kvert than the internal and external conditions (p < 0.05). In the I group, the external condition was associated with significantly higher RSI and kvert and shorter CT than other conditions (p < 0.05). Therefore, this suggests that attentional focus strategies need to be selected depending on DJ experience: A neutral focus may be preferable for athletes experienced in DJs, whereas an external focus may be more suitable for athletes with lesser DJ experience.
O USO DE PARÓDIAS NO ENSINO DE BIOLOGIA: relato de experiência
Authors: Paixão Beatriz Dos Santos , Hohl Rodrigo , Mourão Júnior Carlos Alberto
Published: October 2021

O aprendizado de tópicos em biologia requer o entendimento de nomenclatura específica e não coloquial. As paródias podem aproximar a semântica cultural do aluno aos termos próprios da biologia, promovendo a aprendizagem significativa. O uso de paródias foi analisado durante dois anos (2017-2019) em turmas de ensino fundamental e médio de cinco escolas públicas. Concluímos que a paródia é um instrumento didático de rememoração dos significados e da nomenclatura própria da biologia. É uma metodologia de baixo custo que trabalha de forma criativa conceitos não coloquiais e os significados associados. Entretanto, a paródia em si não gera motivação intrínseca sendo fundamental a exposição incisiva do professor trazendo segurança para o aluno e credibilidade à proposta didática.

Published: October 2021

A crise gerada pelo novo coronavírus traz preocupações cada vez maiores entre as nações de todos os continentes e já altera profundamente as relações políticas e econômicas em escala global. Os impactos causados pela pandemia do coronavírus têm feito com que os países revejam as suas políticas publicas e levantem questionamentos sobre o sistema capitalista enquanto sistema social predominante. Há um reposicionamento de alguns Estados no sentido de adotar um modelo social, político e econômico  que garanta a todos os cidadãos padrões mínimos de saúde e seguridade social. Destarte, o presente artigo tem como objetivo apontar a importância do Estado de Bem-estar Social, seus benefícios em relação às políticas públicas, como é o caso do serviço de saúde pública. Nesse artigo, partimos do pressuposto de que a pandemia gerada pelo coronavírus expõe a fragilidade do modelo neoliberal brasileiro na contenção da crise, uma vez que esse modelo preconiza uma drástica redução do papel do estado na economia favorecendo o setor privado. Com o objetivo de abrir caminho para uma reflexão acerca desta problemática tomaremos como base o materialismo dialético que propõe busca pela explicação dos fenômenos da realidade a partir de condições estritamente concretas. O artigo foi desenvolvido a partir de pesquisa bibliográfica com abordagem qualitativa.

Diante da atual conjuntura de lacunas deixadas pelo Poder Legislativo e da inércia apresentada pelo Poder Executivo, abre-se espaço para o aumento crescente do Ativismo Judicial. O presente trabalho apresentará de forma simples como o ativismo judicial deverá ser exercido pelo Supremo Tribunal Federal em matéria tributária, porém, antes, será apresentado a Teoria da Separação dos Poderes e sua definição concebida por Montesquieu além de fazer ligação entre a democracia e a separação dos poderes. Trazer o conceito de ativismo judicial – movimento que tem ganhado contornos expressivos no cenário judicial brasileiro - controle de constitucionalidade e o elo entre esses dois elementos com a função precípua do STF, a saber, Guardião da Constituição Federal. E por fim, falar brevemente sobre os contornos do ativismo judicial no que tange a matéria tributária.
Exchanging a “Gnawing Thought for “Taking a Pill Once a Day”: Examining Sexual Minority Men's Experiences With PrEP and Mental Health in a Universal PrEP Access Context
Authors: Gagliano Nick , Black Stéphanie , Mniszak Caroline , Morgan Jeffrey , Lachowsky Nathan , Knight Rod
Published: October 2021

This study explores how universal access to and taking no-cost preexposure prophylaxis (PrEP), which effectively prevents HIV acquisition, may impact the mental health-related experiences of sexual minority men, including HIV-related anxiety. We employed community-based and participatory methods to conduct and analyze 27 interviews with sexual minority men in British Columbia, Canada. Before starting PrEP, participants’ experiences with sex were highly associated with HIV-related anxiety. Participants stated they did not explicitly initiate PrEP to reduce HIV-related anxiety, yet many described significant reductions of HIV-related anxiety after starting PrEP. Participants described feeling that the sex they were having was safer following their initiation of PrEP, which resulted in increased ability to access heightened experiences of pleasure, desire, and intimacy. PrEP's capacity to impact HIV stigma and health broadly should continue to be explored, particularly given the mental health inequities faced by those who may acquire HIV.

Very few studies have focused on the relationship between cognitive functions and clinical features in borderline personality disorder (BPD). Subjects with BPD and healthy controls were administered the Repeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test A and B, and the Wisconsin Card Sorting Test. The Brief Symptom Inventory (BSI-53) was used to assess the severity of current symptoms. Attachment style was assessed with the Experiences in Close Relationship Questionnaire, identity integration with the Personality Structure Questionnaire, and other domains of personality dysfunction with the RUDE Scale for Personality Dysfunction. Patients with BPD performed significantly worse than healthy controls in all cognitive domains. Cognitive functions, particularly delayed memory and visuospatial abilities, displayed meaningful associations with trait-like clinical features, above the effect of global cognition and state psychopathology. These findings highlight the need to evaluate effects of cognitive rehabilitation on trait features among individuals with BPD.

Borderline personality disorder (BPD) typically has an onset in adolescence. Nonsuicidal self-injury (NSSI) could be associated with its subsequent development. The aim of this study was to examine whether NSSI among adolescents in the community is associated with a risk for BPD in emerging adulthood. Sixty-nine adolescents (11-13 years old) with a history of NSSI and 61 matched controls were assessed for NSSI and then reassessed between ages 18 to 20 years. Findings showed that continuation of NSSI over time was associated with higher ratings of BPD symptomatology and greater impairment in psychosocial functioning. Both of these relations were mediated by deficits in emotion regulation. These results suggest that adolescents who engage in NSSI may need to be assessed for problems regulating emotions and to be provided with early interventions to help prevent continuation of NSSI.
Enhancing Assessment Literacy in Professional Counseling: A Practical Overview of Factor Analysis
Authors: Kalkbrenner Michael T.
Published: October 2021

Assessment literacy is an essential competency area for professional counselors who administer tests and interpret the results of participants’ scores. Using factor analysis to demonstrate internal structure validity of test scores is a key element of assessment literacy. The underuse of psychometrically sound instrumentation in professional counseling is alarming, as a careful review and critique of the internal structure of test scores is vital for ensuring the integrity of clients’ results. A professional counselor’s utilization of instrumentation without evidence of the internal structure validity of scores can have a number of negative consequences for their clients, including misdiagnoses and inappropriate treatment planning. The extant literature includes a series of articles on the major types and extensions of factor analysis, including exploratory factor analysis, confirmatory factor analysis (CFA), higher-order CFA, and multiple-group CFA. However, reading multiple psychometric articles can be overwhelming for professional counselors who are looking for comparative guidelines to evaluate the validity evidence of scores on instruments before administering them to clients. This article provides an overview for the layperson of the major types and extensions of factor analysis and can serve as reference for professional counselors who work in clinical, research, and educational settings.

There is a very high demand for the American Petroleum Institute (API) grade baryte in Nigeria due to the continuous massive drilling in oil and gas fields. Considering the presumption that local baryte is of low quality, processed baryte is imported, leading to great national revenue losses. Some baryte deposits in the Northern Cross River, Nigeria were sampled and studied in field and laboratories, based on API standard requirements (2004 and 2010), to ascertain their suitability for use as weighting additive in drilling fluids. Furthermore, flame testing of the samples yielded yellowish-green flame indicating barium presence; X-ray diffraction (XRD) and X-Ray fluorescence (XRF) analyses confirmed the mineralogy and chemical composition of the samples, respectively. The results revealed the Specific Gravity, SG range of 4.37 to 4.52; concentration of alkali earth metals as calcium 8.40mg/kg to 62.10mg/Kg; the residue >75micron and particle sizes <6microns processed had normal range, respectively below 3% and 30%; and the samples’ BaSO4 %weightcomposition was over 90%. The chemical analysis indicated no significant undesired minerals. Galena gangue with baryte was observed in three locations though these could be easily beneficiated through physical separation. The tests and analyses result qualified the Northern Cross River baryte samples as high-grade API standard baryte, suitable for oilfield drilling fluid. Further estimation of the baryte reserves in this region was highly recommended, as this might proffer a substantial solution to the sustainable supply of excellent local quality drilling baryte in Nigerian oilfields.

Expansion of industrial areas, aquaculture, settlements, and limited knowledge of the community about the function of mangroves allegedly led to the conversion of mangrove functions in the early 1990s. This study aimed to map the condition of mangroves from 1988, 1990, 1995, 2008, to 2021 and their effect on the widespread of tidal flooding in three villages (Mangkang Kulon, Mangunharjo, Mangkang Wetan) in Tugu subdistrict, Semarang City. The research method was carried out by using spatiotemporal analysis of Landsat 5 and Landsat 8 imagery through the supervised approach (Maximum Likelihood algorithm). In order to map the correlation of mangrove damage with the widespread impact of tidal flooding, an overlay analysis of land use maps was carried out in 1988, 1990, 1995, 2008 and 2021. The results of the study showed that mangrove damage is correlated with the widespread of tidal flooding that drowns settlements, ponds, and agricultural land. Data analysis showed that the mangrove area in three villages has decreased from 1988 to 2021, covering an area of 242.66 ha. This condition is one of the triggers for the increase in tidal flooding area from 1988 to 2021, covering an area of 253.135 ha. As a natural barrier to prevent abrasion and tidal flooding, mangrove conservation is very necessary, considering the impact of tidal flooding on the coast of Semarang City is increasingly widespread.

Land degradation is currently a major environmental problem that can lead to decreasing biomass productivity. The causes of land degradation have been widely reported. However, the soil morphological characteristics and its detailed properties related to land degradation need to be investigated further. The research was conducted in North Halmahera Regency in March-April 2020. The study started with an overlay of basic maps such as rainfall, land use, topography, and soil types to map the degraded land units. Several land units classified from slightly damaged to severely damaged will be validated based on field observations and supported by laboratory measurements. Characterization of soil morphology and soil sampling was carried out according to USDA international standards. Sentinel 2A image and SRTM image from March to April 2020 were used to determine NDVI and TRI. The characteristics of the soils that have not been degraded tend to be found in volcanic landscapes, while those of the degraded soils tend to be found in structural and karst hills. The thickness of the degraded soil horizons tends to be shallower with an incomplete horizon arrangement, and many rock fragments are found in the soil surface layer. SOC gradually decreases in degraded soils, while the essential nutrients (N, P, and K) are relatively more varied across soil types. The improper land use without conservation on steep slopes causes the soils to be easily degraded. The soil degradation index has a linear relationship with NDVI and TRI. Thus, the revitalization of degraded lands needs to pay attention to the layout and types of vegetation with different slope levels according to the geomorphological zone.
Getting Freaky with Missy
Authors: Powell Elliott H.
Published: October 2021

This article analyzes the music of Black female rapper Missy Elliott in order to consider performative challenges to the politics of visibility and visuality of Black queerness in hip hop. While mainstream media lauds the recent increase in and representation of out Black LGBTQ rappers, scholars such as C. Riley Snorton caution such praise for the unique ways visibility and surveillance are entangled formations that render Black queer communities vulnerable to violence. This article draws on Elliott’s songs “Get Ur Freak on” and “Pussycat” to present alternative ways of navigating the violence of visibility for Black queers and queerness. It argues that Elliott musically inhabits, expresses, and produces queerness through a set of cultural practices that this article calls the “musical aesthetics of impropriety.” The musical aesthetics of impropriety are performative expressions that are developed and deployed at the level of the sound recording, and that exploit the gaps and fissures of what qualifies as proper sexual subjects (e.g., LGBT) and how we come to perceive them as such (i.e., “evidence“) in order to produce alternative sexual and sonic formations. It is, thus, through the musical aesthetics of impropriety that we might imagine and articulate racialized queerness in hip hop differently.

Inappropriate corpus luteum (CL) regression can produce pregnancy loss. An experimental model was utilized to investigate regression of accessory CL during pregnancy in dairy cows. Cows were bred (day 0) and treated with gonadotrophin-releasing hormone 6 days later to form accessory CL. Transrectal ultrasound (every other days) and blood samples for progesterone (P4; daily) were performed until day 56 of pregnancy. On day 28, 13 cows were confirmed pregnant, and accessory CL were found contralateral (n = 9) or ipsilateral (n = 4) to previous ovulation. On day 18, CL biopsy was performed to analyze mRNA expression for interferon-stimulated genes (ISGs). Luteolysis occurred more frequently in cows that had contralateral accessory CL (88.9% (8/9)) than in cows with ipsilateral accessory CL (0% (0/4)). Luteolysis of contralateral accessory CL occurred either earlier (days 19–23; 2/8) or later (days 48–53; 6/8) in pregnancy and occurred rapidly (24 h), based on daily P4. After onset of earlier or later accessory CL regression, circulating P4 decreased by 41.2%. There was no difference in luteal tissue mRNA expression for ISGs on day 18 between accessory and original CL and between CL that subsequently regressed or did not regress. On day 56, an oxytocin challenge dramatically increased prostaglandin F2α metabolite (PGFM) in all cows but produced no pregnancy losses, although cows with previous accessory CL regression had greater PGFM. In summary, ipsilateral accessory CL did not regress during pregnancy, whereas most contralateral CL regressed by 63 days of pregnancy, providing evidence for local mechanisms in regression of accessory CL and protection of CL during pregnancy.
