Authors: Servaramuthu Balakrishnan , Nagendraraj Thavasilingam , Annaraj Jamespandi
Published: May 2023

Mononuclear copper(II) complexes based on the symmetric tridentate N3-donor ligands bis(pyridin-2-yl)methyl)amine (HBPA, L1) and its methylated counterpart, di(2-pyridylmethyl)amine (MeDPA, L2) have been prepared, characterized, and demonstrated as the functional models for lytic polysaccharide monooxygenase. These complexes disrupt the synthetic substrate, such as p-nitrophenyl--D-glucopyranoside (-PNPG) into p-nitrophenol (PNP) and D-allose via oxidative cleavage as LPMOs do in nature. The observed spectroscopic and kinetic analysis have revealed that the reaction proceeds via copper(II) hydroperoxide as intermediate, whose electronic spectral signature has appeared at 350 nm in the electronic absorption spectra with the formation rate of 1.61 and 9.06 × 10-3 s1 respectively for complexes 1 and 2. Especially the obtained product was newly appeared at 400 nm, indicates the formation of p-nitrophenol with the rate of 7.52 and 5.45 × 10-3 s1.for complexes 1 and 2 respectively. These results affirm the ability of copper complexes as the functional models of LPMOs.

Authors: Arora Bhawana , Mishra Pallavi
Published: May 2023

The mandelic acid oxidation has been carried out by benzimidazolium fluorochromate (BIFC), morpholinium fluorochromate (MFC), benzimidazolium dichromate (BIDC), morpholinium chlorochromate (MCC) and tetraethylammonium chlorochromate (TEACC) using different solvents as dimethyl sulphoxide (DMSO), dimethyl formamide (DMF), chloroform (CF), acetone, dichloromethane (DCM) and 1,2-dichloroethane (DCE) at 308K, which results in the corresponding oxoacids formation. By using the TOPSIS method, we analysed the solvent effect and found the order by the solvent’s performance score for the reaction as DMSO>DMF>DCE>ACETONE>DCM>CF. The oxidation with all the oxidants resulted in the formation of corresponding oxo acid. The mechanism involved the construction of a cyclic chromate ester in a fast pre-equilibrium and then the decomposition of the ester in a subsequent slow step via a cyclic concerted symmetrical transition state leading to the formation of corresponding oxo acid in all the cases.

Authors: Jepsen S. Dee , Kilanowski Jill F. , Drerup Emilee A. , Brinkman Patricia , Duffy Sonia A.
Published: May 2023

Highlights

Most farmers never had a skin cancer assessment by a health professional, but almost 20% had a skin cancer diagnosis.

While at risk for skin cancer, Ohio farmers have not widely adopted sun safety protection behaviors.

Understanding sun safety practices of farmers may guide development of appropriate resources and interventions.

Abstract. The purpose of the study was to identify sun exposure risk factors and sun protection behaviors from a sample of Ohio farmers. A convenience sample of farmers was invited to complete a self-report survey, either online or by paper and pencil at annual pesticide training courses and community-based safety programs. This cross-sectional and descriptive study used public domain survey questions by Glanz et al. and Oh et al. Respondents totaled 505 and self-identified primarily as male, married or with a domestic partner, white, non-Latino, with very fair to fair skin, and worked full-time mostly in field crops. Over 50% of farmers applied or reapplied sunscreen. Between 50% and 70% wore a shirt with sleeves, sunglasses, and/or a hat; a baseball cap was the preferred headwear. Farmers (67%) reported 0-1 sunburns last year, and 83% said they sit in the sun to get a tan. Younger farmers (<44 years old) spent more time in the sun to tan and reported fewer painful sunburns. Most farmers (58%) never had a professional skin cancer assessment, but 17% had a skin cancer diagnosis. While at risk for skin cancer, Ohio farmers have not widely adopted sun safety protection behaviors. Data may direct future multidisciplinary health and safety educational programming by state Extension outreach and healthcare providers.

Published: May 2023

The compound CyNH3[HOOC(CH)2COO]·H2O has been obtained using one pot-synthesis process by mixing, in methanol, HOOC(CH)2COOH, CyNH2 and SnPh3Cl in a 1:1:1 molar ratio. X-ray diffraction analysis of the compound reveals that in the crystal structure, hydrogen maleate [HOOC(CH)2COO]- in cis configuration interacts with [CyNH3]+ cations and water molecules to generate an R66(22) ring. The interconnections of the rings via simple (N–H··O and O–H··O) and bifurcated (N–H···(O, O)) hydrogen bonds give rise to a 2D supramolecular structure.

Published: May 2023

: Cancer is one of the fastest-growing epidemics that affect millions yearly. A handful of anticancer drugs are available on the market, but they produce undesirable side effects. Currently, tubulin inhibitors targeting the colchicine binding site are considered an important target due to their structural simplicity and favorable pharmacokinetics with fewer side effects. Different researchers conducted many studies to discover a novel tubulin inhibitor targeting the colchicine binding site with high safety and potency. In the present study, we performed computational analysis of 48 styrylquinolines analogs obtained from literature using different drug designing tools. The pharmacophore mapping study was conducted to identify the important pharmacophoric features essential for biological activity. Atom-based 3D-QSAR (3-dimensional quantitative structure-activity relationship) analysis was carried out to know the contribution of different atoms to model development. The generated model showed a statistically significant coefficient of determinations for the training and test sets. The best QSAR model was selected based on R2 (0.8624) and Q2 (0.6707) values. Contour plot analysis of the developed model unveiled the chemical features necessary for tubulin inhibition. A docking study was performed on potent styrylquinoline analog 9VII-f(46), which shows the highest SP docking scores (-5.494). ADME (Absorption, distribution, metabolism, and excretion) analysis provides valuable information about the drugability of newly designed compounds.
Influence of the activation method on the activity of the nickel catalyst
Authors: Zeynalov Elshan Tofig
Published: May 2023

The results of a comparative analysis of the influence of the activation method on the catalytic properties of a nickel diatomaceous earth catalyst during the conversion of isopropyl alcohol to acetone are presented. Studies of the activity of the catalyst in the reaction of gas-phase dehydrogenation of isopropyl alcohol were carried out on a flow-type laboratory installation at a temperature of 150-350ºC. The mechanical activation of the nickel diatomaceous earth catalyst was carried out in a planetary mill. Traditional activation included pre-heat treatment of nickel diatomaceous earth catalyst in an atmosphere of O2 and H2 at 250°C; IR radiation was carried out using an incandescent lamp. It is shown that the nature of the activator determines the features of the formed surface nickel complexes. The activity of samples of the nickel diatomaceous earth catalyst subjected to activation by thermal reduction and thermal oxidation, as well as IR irradiation, testified to the low efficiency of these methods. A comparison of the activity of industrial nickel diatomaceous earth catalyst samples subjected to different activation methods showed that processing of samples by thermal reduction and thermal oxidation slightly increases the yield of acetone. In contrast, the original catalyst's IR irradiation and mechanical activation decreased its activity. Thus, thermal reduction and oxidation methods are promising for further research to increase the industrial nickel diatomaceous earth catalyst activity in dehydrogenating isopropyl alcohol into acetone.

Published: May 2023

The purpose of this study was to determine whether FABP1 and FAS regulate expression of collagen and its crosslinking via lysyl oxidase in isolated adipocytes from Zongdihua pigs. We aimed to identify biochemical processes affecting meat quality using molecular tools to provide a basis for breeding improvement of these animals. We measured expression levels of FABP1 and related genes using qRT-PCR in longissimus dorsi muscle and subcutaneous adipose tissues. Primary adipocytes from fat tissues were isolated and FABP1 and FAS were over-expressed from recombinant plasmids. Sequence analysis of the cloned genes indicated that FABP1 encodes a hydrophobic protein of 128 amino acids and contained 12 predicted phosphorylation sites and no transmembrane regions. The basal levels of FABP1 and FAS expression in pig tissues were 3–3.5-fold higher in subcutaneous fat compared with muscle (P < 0.01). Recombinant expression plasmids were successfully transfected into the cloned preadipocytes and (a) over-expression of FAS resulted in significantly increased expression of COL3A1 (P < 0.05) and significantly inhibited lysyl oxidase LOX expression (P < 0.01); (b) over-expression of FABP1 significantly increased COL3A1 expression (P < 0.01) and significantly inhibited LOX expression (P< 0.05) and significantly reduced lysyl oxidase activity (P < 0.01). Therefore, FAS enhanced FABP1 expression resulting in increased collagen accumulation and this preliminarily suggested that FAS and FABP1 can serve as fat-related candidate genes and provide a theoretical basis for the study of fat deposition in Zongdihua pigs.
Flow chamber staining modality for real-time inspection of dynamic phenotypes in multiple histological stains
Authors: Li Zhongmin , Muench Goetz , Goebel Silvia , Uhland Kerstin , Wenhart Clara , Reimann Andreas
Published: May 2023

Traditional histological stains, such as hematoxylin-eosin (HE), special stains, and immunofluorescence (IF), have defined myriads of cellular phenotypes and tissue structures in a separate stained section. However, the precise connection of information conveyed by the various stains in the same section, which may be important for diagnosis, is absent. Here, we present a new staining modality—Flow chamber stain, which complies with the current staining workflow but possesses newly additional features non-seen in conventional stains, allowing for (1) quickly switching staining modes between destain and restain for multiplex staining in one single section from routinely histological preparation, (2) real-time inspecting and digitally capturing each specific stained phenotype, and (3) efficiently synthesizing graphs containing the tissue multiple-stained components at site-specific regions. Comparisons of its stains with those by the conventional staining fashions using the microscopic images of mouse tissues (lung, heart, liver, kidney, esophagus, and brain), involving stains of HE, Periodic acid–Schiff, Sirius red, and IF for Human IgG, and mouse CD45, hemoglobin, and CD31, showed no major discordance. Repetitive experiments testing on targeted areas of stained sections confirmed the method is reliable with accuracy and high reproducibility. Using the technique, the targets of IF were easily localized and seen structurally in HE- or special-stained sections, and the unknown or suspected components or structures in HE-stained sections were further determined in histological special stains or IF. By the technique, staining processing was videoed and made a backup for off-site pathologists, which facilitates tele-consultation or -education in current digital pathology. Mistakes, which might occur during the staining process, can be immediately found and amended accordingly. With the technique, a single section can provide much more information than the traditional stained counterpart. The staining mode bears great potential to become a common supplementary tool for traditional histopathology.

Published: May 2023

Objective

Investigate the association between adverse childhood experiences and pre-pregnancy body mass index (BMI) in a population-based cohort in Trøndelag county, Norway.

Materials and methods

We linked data from the third (2006–2008) or fourth (2017–2019) survey of the Trøndelag Health Study (HUNT) and the Medical Birth Registry of Norway for 6679 women. Multiple logistic regression models were used to examine the association between adverse childhood experiences and pre-pregnancy BMI. Adverse childhood experiences were self-reported in adulthood and included perceiving childhood as difficult, parental divorce, parental death, dysfunctional family environment, bad childhood memories and lack of support from a trusted adult. Pre-pregnancy BMI was derived from the Medical Birth Registry of Norway or BMI measurement from the HUNT survey conducted within 2 years prior to the woman’s pregnancy.

Results

Perceiving childhood as difficult was associated with higher odds of pre-pregnancy underweight (OR 1.78, 95%CI 0.99–3.22) and obesity (OR 1.58, 95%CI 1.14–2.2). A difficult childhood was positively associated with obesity with an adjusted OR of 1.19, 95%CI 0.79–1.81 (class I obesity), 2.32, 95%CI 1.35–4.01 (class II obesity) and 4.62, 95%CI 2.0–10.65 (class III obesity). Parental divorce was positively associated obesity (OR 1.34, 95%CI 1.10–1.63). Bad childhood memories were associated with both overweight (OR 1.34, 95%CI 1.01–1.79) and obesity (OR 1.63, 95%CI 1.13–2.34). Parental death was not associated with pre-pregnancy BMI.

Conclusions

Childhood adversities were associated with pre-pregnancy BMI. Our results suggest that the positive associations between childhood adversities and pre-pregnancy obesity increased with increasing obesity level.

Published: May 2023

Objective of the study: this editorial aims to present an overview of Brazilian quantitative research in entrepreneurship, as well as describing possibilities for advancing this methodological approach. Methodology and approach: the article consists of an editorial publication, built from bibliographic research of entrepreneurship literature and theoretical reflections. Main Results: Most national entrepreneurship research follows a qualitative approach. Despite its relevance, quantitative research also has multiple potentialities, especially associated with the use of data originating from secondary sources. Main theoretical and methodological contributions: We present public databases that can be used by entrepreneurship researchers to advance theory. Some strategies for using these bases are exemplified through a brief tutorial in R language. We further debate about strategies to strengthen quantitative research in the area. Finally, we bring a research agenda. Relevance/Originality: contents that are still little explored in the national literature are presented, such as the use of secondary data and machine learning. Social and managerial contributions: some of the databases presented in the study come from government sources and can be used to support the construction of public policies for entrepreneurship. In addition, the precepts on quantitative research presented in this editorial can support managers who work with data analysis to perform more robust studies, regardless of the area, whether practical or academic.
Effects of photovoltaic systems on the behavior of harmonic components in low voltage network
Authors: Lipták Róbert , Bodnár István
Published: May 2023

Renewable energy sources, especially solar systems, have become increasingly important energy sources in recent times. Connecting large PV systems to utility networks can cause a number of operational problems for distribution networks. The extent of these problems depends directly on the percentage of PV penetration and the geographical location of the installation. Possible problems caused by PV systems: over-voltage, output power fluctuation, harmonic distortion, frequency fluctuation

Harmonic distortion is a serious energy quality problem which can occur in photovoltaic systems due to the use of power inverters that convert direct current to alternating current. The resulting harmonics can cause parallel and series resonances, transformer overheating, and protection device malfunctions, which can reduce the reliability of power supply systems.

Analysis Of The Influence Of Company Size, Economic Performance, Leverage, And Foreign Ownership On Corporate Social Responsibility Disclosure
Authors: Rasyid Dwiyan Al
Published: May 2023

Purpose: This research aims to analyze the relationship between leverage, profitability, and foreign ownership on the disclosure of Corporate Social Responsibility in the mining sector listed on the Indonesia Stock Exchange (IDX). This study was conducted because, nowadays, companies globally are not only oriented toward high performance profits, but also towards social and environmental issues.

Methodology: The population of this research was 114 mining companies listed on the IDX during 2013-2015, with purposive sampling techniques resulting in 87 mining companies. Multiple linear regression analysis was used to determine the effect of independent variables (company size, economic performance, leverage, and foreign ownership) on the dependent variable of Corporate Social Responsibility. The Corporate Social Responsibility index was measured using indicators disclosed by companies with the number of indicators set out in the G4 by the Global Reporting Initiative (GRI). Company size was determined by the amount of assets, Economic Performance was defined by return on assets (ROA), leverage was defined by the debt-to-asset ratio (DAR), and Foreign Ownership was defined by the amount of foreign ownership divided by the number of outstanding shares.

Findings: The results of this research show that Company Size, Economic Performance, and Foreign Ownership influence the disclosure of Corporate Social Responsibility, in contrast, Leverage does not influence the disclosure of Corporate Social Responsibility.

Novelty: This research uses a more comprehensive measurement standard for CSR disclosure than previous research, which used the G3 version 3.0 standard with 79 disclosure items. In this research, the G4 version 4.0 standard released by the Global Reporting Initiative (GRI) is used, which has 91 disclosure items

Keywords:  Corporate Social Responsibility, Company Size, Economic Performance, Leverage, and Foreign Ownership.

Published: May 2023

The purpose of this research was to examine the perspectives of academicians on distance education activities during the pandemic from various aspects. The research study was carried out using a case study design, which is one of the qualitative research methods. The perspectives of 24 academicians working at a state university were explored, and the data collected through an online platform using a structured interview form were analyzed by utilizing the content analysis method. The findings were reported in the form of themes, sub-themes, and codes, supported by participant expressions. Results indicated that academicians faced infrastructure-related problems during the pandemic process, which arose from various aspects. They expressed that distance education applications would be appropriate to use, especially in social sciences, theoretical courses, and crowded classrooms in the post-pandemic period. However, using distance education in math, sciences, and engineering may be inconvenient and create an inequality of opportunity. Academicians also stated that they experienced technical issues during the distance education process, open-to-abuse exams, low participation in classes, and problems in accessing education for students. They emphasized that encountering cases of cheating and plagiarism regarding the measurement and evaluation processes is an important deficiency. Furthermore, academicians made suggestions regarding distance education applications such as maintaining the hybrid teaching model, examining the practices of leading universities, introducing a new model, integrating virtual classroom applications into the process, or introducing existing interactive systems into the system.

Xanthomonas campestris pv. campestris merupakan bakteri penyebab penyakit busuk hitam (black rot) pada kubis. Petani masih mengandalkan pestitida sintetis azoksistrobin dan difenokonazol untuk mengendalikan penyakit pada tanaman kubis yang dikhawatirkan akan berdampak pada keanekaragaman X. campestris pv. campestris. Tujuan penelitian ialah mendapatkan data keanekaragaman secara genetik dan fenotipik isolat bakteri X. campestris pv. campestris, serta mendapatkan data respons resistensi isolat bakteri tersebut terhadap campuran bahan aktif azoksistrobin dan difenokonazol. Penelitian terdiri atas lima tahapan, yaitu (1) pengambilan sampel pada lahan yang terdapat gejala busuk hitam; (2) isolasi bakteri menggunakan teknik penanaman jaringan; (3) seleksi isolat dengan uji sifat Gram, hipersensitif, hidrolisis pati, dan patogenesitas; (4) identifikasi menggunakan primer spesifik dan universal 16S rRNA; dan (5) analisis keanekaragaman genotipe dengan metode RFLP in silico dan keragaman fenotipe dengan mengukur bobot eksopolisakarida. Hasil karakterisasi dan identifikasi secara molekuler diperoleh lima isolat bakteri X. campestris pv. campestris, yaitu CLT01, CDA08, SDA02, SDA22, dan SDA26. Hasil analisis keanekaragaman genotipe menunjukkan bahwa kelima isolat memiliki keanekaragaman berdasarkan pemotongan fragmen DNA gen 16S rRNA, sedangkan keragaman fenotipe ditunjukkan dengan nilai inhibition consentration (IC) yang berbeda-beda. Isolat SDA22 memiliki nilai IC50 paling tinggi dan keanekaragaman secara genetik yang berbeda dibandingkan dengan  isolat X. campestris pv. campestris lainnya. Penggunaan pestitida sintetis azoksistrobin dan difenokonazol secara terus-menerus dalam jangka waktu lama dikhawatirkan berdampak pada patogen seperti X. campestris pv. campestris. Oleh karena itu, alternatif pengendalian yang lain diperlukan agar tidak terjadi resistensi pada X. campestris pv. campestris.

Introduction: Fatigue is a characteristic symptom and is often found in CHF patients and has a negative effect on daily activities, disease prognosis, and patient's quality of life. However, fatigue is a common symptom that is often overlooked and ignored. Limited study explored fatigue in CHF patients. The aim of this study was to explore fatigue in CHF patients. Methods: The research design is a descriptive survey. The total research sample is 85 respondents. Data were taken using a Multidimensional Assessment Fatigue (MAF) questionnaire with univariate data analysis in the form of a frequency distribution. Respondents involved in the study were patients aged >18 years who suffered from CHF based on a doctor's diagnosis and confirmed by medical records. Results: The majority of respondents are elderly with female gender, work as household workers, and heve income less than Rp1,500,000/month. Examination of vital signs performed on the majority of CHF patients showed normal temperature (36.5℃ - 37.5℃), pre-hypertensive blood pressure (120/80 - 139/89 mmHg), normal pulse (60-100x/min), and normal respiratory rate (12-20x/minute). Most patients have a CHF duration of 1–3 years, and are in grades 2 and 3 based on the New York Association (NYHA) classification. The results of this study were 65.9% of CHF patients experienced moderate fatigue, 17.6% severe fatigue, and 16.5% mild fatigue. Conclusion: Health services can consider efforts to improve the quality of nursing services in overcoming or minimizing fatigue experienced by CHF patients. These efforts can be a therapy, evidence-based health education, or fatigue monitoring for preventing a worsening of disease prognosis and improving the patient's quality of life. Keywords: CHF, Fatigue, Multidimensional Assesment Fatigue.

Stocks are evidence of equity participation in a company. Investors need to know the quality of stock prices so that they can minimize losses when investing. Technical analysis can be used by investors to decide when to buy or sell a stock. One of the technical analysis that can be used on stock prices is using quality control. Control charts can be used to make decisions in stock trading activities. The Exponentially Weighted Moving Average control chart is very useful for detecting small shifts such as in financial data. The assumption that must be fulfilled in using the EWMA control chart is that the data is normally distributed. The non-fulfillment of the normal distribution assumption causes the EWMA control chart produces plots that are far from the control limits. This problem can be solved using the nonparametric EWMA Sign control chart. The construction of the nonparametric EWMA Sign control chart on stock prices is expected to overcome the limitations of the standard EWMA control chart and provide a signal to investors to know the best time to trade stocks. The data used in this study is the daily closing price data of PT Bumi Serpong Damai Tbk on March 1, 2021 to March 4, 2022 with a total of 250 data. The nonparametric EWMA Sign control chart shows that the daily closing price data is out of control because it produces plots that are spread out non-randomly and shows a relatively similar pattern.
The Effect of Perceived Value, Brand Image, Satisfaction, Trust and Commitment on Loyalty at XYZ Hospitals, Tangerang
Authors: Trisno Anggreini Oktavia , Berlianto Margaretha Pink
Published: May 2023

Patient loyalty is a significant aspect of marketing strategies in the health industry, including hospitals. Loyal patients will return for treatment and recommend the hospital to others, and this can reduce marketing expenditure. Patient loyalty can be influenced by several factors, such as satisfaction, perceived value, commitment, trust, and brand image. If the patient's necessity meets their expectation, they will be loyal to the hospital. This study aims to find the positive effect of the independent variable, in the form of perceived value and brand image, towards the dependent variable, i.e., loyalty. Furthermore, the mediating variables are trust, commitment, and satisfaction, which can affect loyalty in private hospitals accredited by KARS and JCI. This research was conducted by distributing questionnaires via a google form. The data collected in this study were 261 respondents treated at XYZ Hospital, using a purposive sampling technique. The data in this study were analyzed using partial lease square-structural equation modeling (PLS-SEM) with the SmartPLS application. The results of this study showed that brand image, commitment, and satisfaction have a positive impact on loyalty; the brand image has a positive impact on satisfaction; Perceived value has a positive impact on trust and satisfaction; satisfaction has a positive impact on trust and commitment. Moreover, perceived value and trust do not demonstrate a positive impact on the study.

This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive design approach, including various reinforcement materials and arrangements, was employed to attain the desired foil pitching, while minimising other undesirable deformation modes. The design process involved iterative computational analysis using finite element analysis and a deformation mode analysis based on foil shape parameters. The research showed that the proposed design approach effectively found options to improve the desired foil parameter pitch, while minimising undesirable deformation modes such as blade deflection and foil shape change. Furthermore, the proposed blade design was tested in thruster steering operational conditions and was found to have a pitch change well matched, potentially countering some changes in fluid flow. When compared to Kumar and Wurm’s design, which only focused on the angular orientation of glass reinforcement, the proposed design was found to outperform the twisting by achieving the same twist for a blade half the length. This study provides valuable insights into the utilisation of composite materials in ship propeller design and highlights the potential for further improvement through a composite engineering design approach.
Natural transformations for quasigroupoids
Authors: González Rodríguez Ramón
Published: May 2023

In this paper, we introduce the notions of natural transformation between morphisms of quasigroupoids and between morphisms of weak Hopf quasigroups. Also, we prove that natural transformations between morphisms of finite quasigroupoids come from natural transformations between morphisms of weak Hopf quasigroups and, on the other hand, we obtain that every natural transformation for morphisms defined between pointed cosemisimple weak Hopf quasigroups comes from a natural transformation between finite quasigroupoids.
Convergence properties for coordinatewise asymptotically negatively associated random vectors in Hilbert space
Authors: He Qihui , Pan Lin
Published: May 2023

In this work, the authors study some convergence results including weak law of large numbers, strong law of large numbers, complete convergence, and complete moment convergence for weighted sums of coordinatewise asymptotically negatively associated random vectors in Hilbert spaces. These results improve or extend some corresponding ones in the literature.
Qualitative Analysis of Multiple Sources and Dimensions of Stigma Among Older Adults Living With HIV Infection Released From Corrections
Authors: Kim Sage J. , Ahn Anna , Hu Elise , Peterson Caryn E.
Published: May 2023

While sources of stigma associated with HIV, incarceration, and aging have been explored separately, the concurrent effects of these multiple sources have been understudied. We conducted in-depth interviews with 48 older adults over 50 years of age with HIV infection who were returning from correctional settings concerning their experiences of stigma. Participants described HIV-related stigma substantially more often than incarceration-related stigma and a greater number of stigma experiences as time passed from release. Anticipated stigma experiences were frequently associated with HIV. Enacted stigma was often related to incarceration. Internalized stigma was associated with both HIV and incarceration. However, participants often described aging as a positive experience of gaining wisdom and control over their life. The findings indicated that multiple sources of stigma affect different dimensions of stigma. Postrelease interventions may benefit from addressing increasing experiences of stigma in the rapidly growing population of older adults living with HIV with a history of incarceration.

Residential substance use disorder treatment is designed to treat more severe substance use disorders. Considering the strong association between substance use and HIV, providing HIV prevention services during residential substance use disorder treatment is imperative. However, not all treatment facilities offer the same services, and differences in residential substance use disorder treatment facilities providing HIV prevention services might stem from facility-level characteristics. Using 3 years (2018-2020) of cross-sectional data from the National Survey of Substance Abuse Treatment Services, we examined which treatment facility characteristics were associated with having HIV prevention services. Using a logistic regression model with HIV prevention services as the outcome, we found that facilities that were accredited, engaged in community outreach, and offered assistance with housing and transportation were more likely to provide HIV prevention services. Furthermore, facilities in the Midwest and West were less likely to provide HIV prevention services than those in the South.
Recovering Identity
Authors: Rumpf Cesraéa
Published: May 2023

Recovering Identity examines a critical tension in criminalized women’s identity work. Through in-depth qualitative and photo-elicitation interviews, Cesraéa Rumpf shows how formerly incarcerated women engaged recovery and faith-based discourses to craft rehabilitated identities, defined in opposition to past identities as “criminal-addicts.” While these discourses made it possible for women to carve out spaces of personal protection, growth, and joy, they also promoted individualistic understandings of criminalization and the violence and dehumanization that followed. Honoring criminalized women’s stories of personal transformation, Rumpf nevertheless strongly critiques institutions’ promotion of narratives that impose lifelong moral judgment while detracting attention from the structural forces of racism, sexism, and poverty that contribute to women’s vulnerability to violence.
Michigan’s PBB Disaster
Authors: Fremion Brittany B. , Matyn Marian
Published: May 2023

In 1973, Michigan Chemical Company accidentally shipped a fire retardant (polybrominated biphenyl or PBB) in place of a nutritional supplement to a livestock feed mill, which resulted in one of the largest episodes of contamination in US history. Researchers estimate that eight million people were exposed to PBB. This report from the field explores the ways in which community members with public and academic partners documented and shared this history, finding new ways to commemorate environmental disasters. The evolving and collaborative nature of this work highlights the multiple and fluid forms commemoration can take, providing an example and rationale for how the PBB disaster and other large-scale contaminations might be commemorated.
Clipping for the Commission
Authors: De Ridder Bram
Published: May 2023

This Report from the Field discusses the methodology of “clipping history” developed by the European Union-funded research initiative RETOPEA (Religious Toleration and Peace). This project, launched in 2018, uses the history of religious toleration to stimulate educational and policy-related reflection on contemporary religious coexistence. The article discusses the initial doubts about doing public history within conditions pre-set by the European Commission; the difficulties faced by the academically trained researchers in handling the educational and digital ambitions of the project; and the eventual strategies that the researchers followed to produce sufficiently contextualized “clippings,”—short pieces of historical information that European teenagers could use to reflect on the topic of religious coexistence.
EDUARDO LOURENÇO: UM POETA DA FILOSOFIA
Authors: Natário Celeste
Published: May 2023

En este estudio, Tempo e Poesia fue la obra de Eduardo Lourenço que más utilizamos para nuestras consideraciones. No sólo porque fue en esta obra donde su ensayismo cobra mayor expresión, sino, al mismo tiempo, porque tiempo-poesía es el binomio o el binomio temático, que, tanto a nivel existencial como ontológico, esclarece mejor el pensamiento de nuestro autor.

Los ensayos de Eduardo Lourenço tienen siempre o casi siempre un ritmo existencial y ontológico, ya sea cuando vuelve la mirada a la definición de cultura, con sus mitos y aventuras (sin análisis equivalente en otro autor portugués del siglo XX), o cuando analiza la expresión del pensamiento de sus primeros interlocutores más cercanos como Kierkegaard y Camus, o incluso cuando lee críticamente la obra de la mayoría de los poetas del siglo XX en Portugal.
Dialéctica y kénosis kafkiana
Authors: Proto Gutierrez F.
Published: May 2023

Intentaremos una interpretación de Die Verwandlung de Franz Kafka, a la luz de los instrumentos teóricos que conforman el corpus marxiano, y en relación con la dialéctica master-slave esbozada por Hegel. Nos serviremos para tal propósito del ensayo de Rodolfo Lemos Morgan El tema del hombre en Franz Kafka y de la antología de ensayos compendiada por el Centro de Estudios Germánicos de Buenos Aires, a 100 años del nacimiento del escritor de Praga.
Un formalismo estético viable
Authors: Zangwill N.
Published: May 2023

En este artículo, sostengo que hay mucho de verdadero en el formalismo. Ofrezco una explicación de cómo los valores estéticos no-formales se relacionan con los valores formales y otros aspectos de la obra de arte. Mi explicación de las propiedades formales hace uso de la noción kantiana de belleza adherente, y nos permite formular una posición de “formalismo moderado”. Examino el modo como dicha explicación procede con respecto a las artes de la pintura representacional, la arquitectura, la literatura y la música. En cada uno de estos casos, mostraré que el mejor modo de entender los fenómenos propios de cada una de estas artes es en términos de un formalismo moderado.
