We present integral field, far-infrared (FIR) spectroscopy of Mrk 54, a local Lyman continuum emitter, obtained with FIFI-LS on the Stratospheric Observatory for Infrared Astronomy. This is only the second time, after Haro 11, that [C ii] 158 μm and [O iii] 88 μm spectroscopy of the known LCEs have been obtained. We find that Mrk 54 has a strong [C ii] emission that accounts for ∼1% of the total FIR luminosity, whereas it has only moderate [O iii] emission, resulting in the low [O iii]/[C ii] luminosity ratio of 0.22 ± 0.06. In order to investigate whether [O iii]/[C ii] is a useful tracer of f
esc (LyC escape fraction), we examine the correlations of [O iii]/[C ii] and (i) the optical line ratio of O32 ≡ [O iii] 5007 Å/[O ii] 3727 Å, (ii) specific star formation rate, (iii) [O iii] 88 μm/[O i] 63 μm ratio, (iv) gas-phase metallicity, and (v) dust temperature based on a combined sample of Mrk 54 and the literature data from the Herschel Dwarf Galaxy Survey and the LITTLE THINGS Survey. We find that galaxies with high [O iii]/[C ii] luminosity ratios could be the result of high ionization (traced by O32), bursty star formation, high ionized-to-neutral gas volume filling factors (traced by [O iii] 88 μm/[O i] 63 μm), and low gas-phase metallicities, which is in agreement with theoretical predictions. We present an empirical relation between the [O iii]/[C ii] ratio and f
esc based on the combination of the [O iii]/[C ii] and O32 correlation, and the known relation between O32 and f
esc. The relation implies that high-redshift galaxies with high [O iii]/[C ii] ratios revealed by the Atacama Large Millimeter/submillimeter Array may have f
esc ≳ 0.1, significantly contributing to the cosmic reionization.
In the Trenches of the Solar–Stellar Connection. VII. Wilson–Bappu 2022
Authors: Ayres Thomas
Published: April 2023

The Wilson–Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the Ca ii 3934 Å K line and stellar absolute visual magnitude over an astonishing range, from diminutive red dwarfs to bloated yellow supergiants. The WBE signifies a deep connection between the nonclassical, mechanically heated chromosphere and fundamental stellar properties. The present study considers the parallel WBE in the analogous Mg ii k line at 2796 Å, utilizing near-ultraviolet spectra from Hubble Space Telescope (HST), and stellar parameters mainly derived from Gaia. The final sample is 300 stars (301 including the Sun). The high cosmic abundance of magnesium allowed Mg ii k emissions to be recovered in the warmer F-types, at the edge of convection and chromospheric activity, and in low-activity Sunlike dwarfs—situations in which Ca ii K might be too weak to measure. Nevertheless, the derived slope of the Mg ii WBE was similar to previous reports based on the K line; as well as other Mg ii efforts with smaller samples of pre-HST spectra. Further, a decomposition of the Mg ii WBE in temperature, gravity, activity, and metallicity yielded similar results to previous Ca ii work, but with the greater clarity afforded by the large, diverse HST sample. Parametric dependences of the k-line WBE match, tolerably well, predictions based on the “ionization-valve” theory of chromospheric structure. In the end, the WBE is not merely an astrophysical curiosity, but rather informs the question of how chromospheres—arguably the central bastion of nonclassical heating—have come to be.
Two strains Neocosmospora stercicola (Sordariomycetes, Nectriaceae) with high nematicidal activity, isolated from the cysts of Globodera sp. (Heteroderidae) in China

Published: April 2023

Plant-parasitic nematodes (PPNs) are significant pests that result in considerable economic losses in global crop production. Due to the high toxicity of chemical nematicides, there is a need to develop new strategies for nematode control. In this context, nematophagous fungi may offer a viable option for biological control. Two fungal strains (GUCC2212 and GUCC2232) were isolated from cysts of Globodera sp., identified as Neocosmospora stercicola. The fungal filtrates of the strains were evaluated for their nematicidal activity against three species of PPNs: Aphelenchoides besseyi, Bursaphelenchus xylophilus and Ditylenchus destructor. The fermentation filtrates of two strains exhibited substantial toxicity towards the evaluated nematodes, with mortality rates reaching up to 100% within 72 h. Concurrently, N. stercicola also demonstrated predatory and parasitic behavior. The eggs of Globodera sp. were parasitized by the two strains. N. stercicola represents a newly recorded species in China and a novel nematophagous species. In conclusion, the two strains of N. stercicola show promise as biocontrol agents for PPNs management.

Fossil species of bethyline wasps from Dominican amber are revised. Based on a cladistic analysis of female morphological data we recognize a new genus and species, †Crassibethylus dominicanusgen. et sp. nov., which came out as sister group of the clade Odontepyris + Prosierola. We also transfer to Bethylidae a fossil taxon originally described in Sclerogibbidae, placing †Pterosclerogibba Olmi as a new junior synonym under Goniozus Förster, in the new combination †Goniozus antiquus (Olmi). Additionally, the third species of Bethylinae known from Dominican amber, †Goniozus respectus Sorg, is diagnosed and illustrated with color images of the holotype. An identification key to the species of Bethylinae from Dominican amber is provided.
Le goût, l’art et le temps. Culture, individu et société dans la « Critique de la faculté de juger esthétique »
Authors: Lories Danielle
Published: April 2023

L’angle sous lequel Kant aborde le jugement esthétique (de goût) est transcendantal, il s’agit d’établir la possibilité qu’un tel jugement soit de validité universelle et nécessaire. On est donc loin d’une perspective historique sur les arts que développera Hegel. Cependant, les conditions de possibilité recherchées sont celles de jugements appartenant à l’expérience d’individus humains et à celle de l’humanité au cours des siècles. C’est sur la présence de cet aspect temporel du jugement réfléchissant esthétique et de la production des beaux-arts dans la première partie de la troisième Critique et sur ses enjeux que se centre le propos de ce texte.
L’oiseau mazouté : usages et construction d’un symbole (1934-1991)
Authors: Dupuy Michel
Published: April 2023

L’oiseau mazouté fait partie des figures classiques de la marée noire. Affiché au moment de la catastrophe, il finit cependant par être effacé. Son émergence a été lente. Constaté dans les années 1920, victime de pollution chronique, il ne s’impose qu’avec le naufrage de l’Amoco Cadiz en 1978 et après l’épisode du Torrey Canyon en 1967. L’image et l’expression d’« oiseau mazouté » ont donc fini par s’imposer, tout en étant porteur d’un discours qui diffère selon les périodes. Ainsi il devient tour à tour la victime du progrès, d’une société de consommation, d’une manipulation, etc.
Les exclusions de l’antispécisme sur Radio Libertaire, la radio de la Fédération anarchiste
Authors: Patiès Félix
Published: April 2023

L’article propose d’analyser une forme originale de controverse autour de la représentation de la question animale sous sa forme antispéciste sur les ondes de Radio Libertaire, la radio de la Fédération anarchiste à Paris. Cette controverse a généré de nombreuses traces dans les bulletins intérieurs de la Fédération anarchistes ainsi que sur des blogs antispécistes. Des témoignages de militants anarchistes permettent d’étoffer ce corpus. L’étude détaillée de ces sources permet de comprendre les tensions théoriques qui animent les membres de la Fédération anarchiste, à la recherche d’alliés dans la lutte contre toutes les formes d’autorité (Églises, État, Capitalisme), et les militants antispécistes à la recherche de débouchés pour leurs idées, loin des médias dominants qu’ils jugent complices de l’exploitation des animaux. Ces tensions débouchent sur l’exclusion à deux reprises des émissions radiophoniques se réclamant de l’antispécisme sur les ondes de la FA.
Investigation of metallurgical properties of Al-Si-Mg casting alloys with integrated computational materials engineering for wheel production
Authors: Yağcı Tuğçe , Cöcen Ümit , Çulha Osman , Armakan Elvan
Published: April 2023

In this study, integrated computational materials engineering, which is one of the new generation approaches in materials science, was used in the production of aluminum alloy wheels by low pressure die casting method. In casting alloys, the efficiency of grain refinement provided by master alloys added to the melt decreases with increasing silicon content of the alloy. In this context, as-cast properties of silicon reduced (Si: 5.0 wt.%) alloys with different Mg ratios (Mg: 3.0, 5.0, 7.0 wt.%) are discussed using integrated computational materials engineering approaches. It has been evaluated whether the examined alloys can be an alternative to the AlSi7Mg0.3 alloy, which is currently used traditionally in the production of aluminum-based wheels, with their microstructural and mechanical properties. The study consists of three stages which are computer-aided production, pilot production, testing and characterization studies. In computer-aided production, original sub-eutectic compositions were determined in types and amounts of alloying elements, alloy designs were realized and a database was created with a computational materials engineering software. Then, low pressure die casting analysis were performed in a virtual environment by transferring these data directly to the casting simulation software. Thus, the microstructural and mechanical properties of the wheel were obtained computationally on the basis of the varying alloy composition. In the second stage, the virtually designed alloy compositions were prepared and sample wheels were manufactured by the low pressure die casting method on an industrial scale. In the testing and characterization phase, spectral analyses, macro and microstructural examinations, hardness measurements and tensile tests were carried out. As a result of this study, it was determined that the studied alloys could be used in the production of wheels by the low pressure die casting method considering the metallurgical properties expected from the wheel. In addition, it is thought that the mathematical design of the material with integrated computational materials engineering approaches before casting simulations will play an active role in the competitiveness and sustainability of the aluminum industry in technological conditions.

Published: April 2023

The equilibrium isotherms of hexavalent chromium adsorption from water on potassium hydroxide (KOH) activated for mangosteen shell as an adsorbent by carbonization at 400 °C for 2 hours has been researched. The effective specific surface area of a biochar adsorbent is 164 m2/g, and its hexavalent chromium adsorption capacity can be encountered to be replied to on the pH 2.0 with initial feed concentration and temperature. The equilibrium adsorption isotherm models based on the Freundlich, Langmuir, Temkin, Hurkins-Jura, Halsay, Dubinin-Radushkevich, and Jovanovic models have been accompanied to compare the sorbate-sorbent system. The Freundlich isotherm model indicated a good fit with the experimental data for the system studied.
Reference Ranges and Control Limits that are Resistant to Baseline Outliers
Authors: Amaratunga D.
Published: April 2023

Reference ranges and control limits are used in many settings – for example, to assess a person’s health or to monitor the stability of a manufacturing process. Such ranges are established based on a baseline sample of what is considered normal data, but it is not possible to always avoid a few outliers being present even in this sample. If, as is common, the range is calculated using statistics, such as the mean and standard deviation, which could be influenced by outliers, then the use of such a range could adversely affect the decisions made. This can be avoided by constructing the reference range using statistics that are resistant to outliers. In this paper, we studied possible approaches and found two methods that had superior performance overall: one based on MM-estimation and one based on a form of Winsorization.

Authors: Epaarachchi E. A. K. , De Silva B. S. S.
Published: April 2023

Endometriosis is a progressive stirring disease marked by the appearance of endometrial glands and stroma exterior of the uterus. It affects 8%–10% of reproductive-age women and is linked to developing primary or secondary infertility in 30% of these women. The main objective of this systematic review was to critically analyse the current related literature to explore the maternal and neonatal adverse outcomes of pregnancies diagnosed with endometriosis. Pregnant women with endometriosis are more likely to develop negative pregnancy outcomes and complicated neonatal outcomes, and therefore they may benefit from extra screening and early detection. Therefore, eight studies are critically analysed in terms of study design, sample size, sample type, exclusive criteria, comprehensive criteria, data analysis, and key findings based on data availability to identify common adverse outcomes of pregnancies with endometriosis. After critically analysing the eight studies, authors explored that pregnant women diagnosed with endometriosis are at elevated risk to develop Placenta previa, hypertensive disorders, postpartum hemorrhage, emergency caesareans and preeclampsia as common maternal outcomes and premature birth, Low birth weight and stillbirth as common neonatal outcomes. In conclusion, women with endometriosis are at elevated risk of developing adverse maternal and neonatal outcomes in their pregnancies.
An Analysis of Vocabulary Learning Strategies Used by Sri Lankan IT Undergraduates: Frequency, Technology Usage and Performance at a Formative Assessment
Authors: Kalinga J. C.
Published: April 2023

Learning vocabulary is an integral part in language acquisition and acquisition of academic vocabulary is a determinant for the success in an academic context. Therefore, many studies have been conducted to formulate academic vocabulary lists and identifying vocabulary learning strategies. This study seeks to explore the vocabulary learning strategies employed by IT undergraduates when studying academic vocabulary and to examine their performance on academic vocabulary related questions at the mid-term examination which is one of their formative assessments. The sample of the study includes 276 first year IT undergraduates who follow the module English for Academic Purposes in a Sri Lankan non-state university. A questionnaire is used as the research tool to obtain data from the sample and the result of the formative exam is used to examine the performance related to academic vocabulary. According to the data analysis, most of the students often use either monolingual or bilingual dictionary as a strategy for the discovery of a new word meaning. This is more emphasized as they have mentioned that they prefer using dictionary apps as a vocabulary strategy using online. A significant number of students study the spelling, meaning and form of a word and ask for help from their friends as strategies for consolidating a word once it has been encountered. When comparing the marks obtained for the vocabulary related questions at the exam, it is noted that the students have obtained less marks to the question in which they had to replace the underlined word/phrases with a more academic alternative. Thus, students need to adopt more effective strategies to acquire mastery of academic vocabulary. Moreover, they should reflect on the current strategies used by them.
Influences on strategic functioning of the public universities of Sri Lanka: challenges and ground realities
Authors: Vivek Ramakrishnan , Nanthagopan Yogarajah
Published: April 2023

It is considered that the university system of Sri Lanka is less efficient in providing degree programs to suit contemporary societal, economic, and political needs and fails to face the current dynamic environmental changes precipitated by issues such as the COVID-19 pandemic. Researchers have realised that the recent pandemic highly affects the execution of universities in Sri Lanka. Simultaneously, experts have noted the severe lack of focus on identifying the causes of university administration failures. Amidst these claims, this study, as its primary objective, strives to explore the factors that affect the implementation of the strategic initiatives made by public universities in Sri Lanka, adopting a qualitative approach with a multimethod sequential design under a thematic model developed based on a detailed literature review. Accordingly, the first qualitative phase of the study was conducted using archival sources, and the second phase used in-depth interviews. The purposive sampling method was used to conduct the seven interviews with the Registrars and Strategic Directors of selected universities. As a result, the study explores and confirms sixteen factors that affect the implementation of strategic initiatives by public universities in Sri Lanka. The theoretical contribution expected from this exercise is to explore new factors that affect the strategic functioning of public universities, with the support of the Open System Theory (OST) and Resource-Based Theory (RBT) that have monetary value in institutional analysis mechanisms, and help to streamline the universities’ decision-making processes with a focus on enhancing the strategic management practices.
Gendered Narratives in British Immigration Policy: Forced Marriage Policy and the British South Asian Diaspora
Authors: Sahni Anisha
Published: April 2023

Theories surrounding public policy, feminism, and neocolonialism intersect to produce an understanding of the gendered narratives used by politicians to advance their policy agendas. This paper explores how the use of these gendered narratives in British immigration policy toward South Asians—by the government, activists, and the media—reinforces racial bias and co-opts issues of gender-based violence to promote alternate, sometimes racially charged, policy goals. Through a case study on forced marriage, this paper explores how stakeholders perpetuate gendered narratives in forced marriage, security, and immigration policy. This analysis concludes that using an intersectional intimate partner violence policy, rather than specific forced marriage or immigration policies, is a more culturally sensitive approach to addressing the issue. Considering alternate policy approaches to forced marriage demonstrates how gendered narratives subvert attention from issues of gender to those of other, often racialized, policy issues.

Published: April 2023

Objective:

To explore the cardioprotective effect of hesperidin against arsenic trioxide-induced cardiac toxicity in rats.

Methods:

Cardiac toxicity was induced by oral administration of 4 mg/kg arsenic trioxide for 30 days. Hematological, biochemical, electrocardiography, echocardiography, and histopathological examinations were performed.

Results:

Hesperidin decreased the neutrophil-to-lymphocyte ratio, calcium, creatine kinase-myoglobin binding, lactate dehydrogenase, IL-6, and lipid peroxidation, as well as increased sodium and potassium concentration and superoxide dismutase and catalase activity in arsenic trioxide-intoxicated rats. Moreover, it reduced peak systolic velocity and end-diastolic velocity while increasing heart rate. Arsenic trioxide-induced histopathological damage to cardiac tissue was prominently alleviated by hesperidin treatment.

Conclusions:

Hesperidin attenuates arsenic trioxide-induced cardiac toxicity in rats. Therefore, it can be further explored as a cardioprotective agent.

Coronavirus disease 2019
Authors: Boulet Andre P.
Published: April 2023

Coronavirus disease 2019 (COVID-19) pandemic has caused the millions of deaths worldwide. Much of the mortality has been associated with a cytokine storm syndrome in patients admitted to the hospital with acute respiratory distress syndrome. Vast arrays of anti-inflammatory therapies are being explored to decrease the cytokine storm to save the lives. None of these therapies have demonstrated efficacy at all stages of the disease thus underlining its complexity. The current vaccine approach is challenged by the emerging virus variants. A multi-target approaches have been used with success for human immunodeficiency virus and some types of cancer. It has been recently proposed to use the same strategy for COVID-19. With their polymolecular structure, botanical drugs may offer an option within that strategy. Thykamine™, a novel botanical drug, with demonstrated anti-inflammatory, antioxidant, and immunomodulatory effects may become the part of the therapeutic arsenal against COVID-19.
The Application of Internet of Things for the Elderly Health Safety: A Systematic Review
Authors: Dorri Sara , Zabolinezhad Hedieh , Sattari Mohammad
Published: April 2023

The elderly population is projected to increase from 8.5% in 2015 to 12% in 2030 and 16% in 2050. This growing demographic is chronically vulnerable to various age-related diseases and injuries like falling, leading to long-term pain, disability, or death. Thus, there is a need to use the potential of novel technologies to support the elderly regarding patient safety matters in particular. Internet of Things (IoT) has recently been introduced to improve the lifestyle of the elderly. This study aimed to evaluate the studies that have researched the use of the IoT for elderly patients' safety through performance metrics, accuracy, sensitivity, and specificity. We conducted a systematic review on the research question. To do this, we searched PubMed, EMBASE, Web of Science, Scopus, Google Scholar, and Science Direct databases by combining the related keywords. A data extraction form was used for data gathering through which English, full-text articles on the use of the IoT for the safety of elderly patients were included. The support vector machine technique has the most frequency of use compared to other techniques. Motion sensors were the most widely used type. The United States with four studies had the highest frequencies. The performance of IoT to ensure the elderly's safety was relatively good. It, however, needs to reach a stage of maturity for universal use.
Q-Methodology as a Research Design
Authors: Kumar L Manoj , George Rinu J , Kunjavara Jibin , Anisha PS
Published: April 2023

Scientific research uses objective facts to build evidence. Due to restrictions in collecting objective data from study subjects and study aims, researchers may need to acquire subjective data. In such cases, qualitative and mixed-method designs are essential in medicine and allied fields. Medical and nursing research increasingly uses qualitative and mixed-method techniques. Mixed methods assess study participants' perspectives, opinions and outlooks on specific occurrences. Subjective data collection is like searching in the sea; potential data may be overlooked. Q-technique collects and analyses subjective data from study participants on a given topic. Q-methodology, Q-sort and Q-techniques are commonly used interchangeably, but they have different meanings. Q might be a data-gathering method or a study approach. This article discusses the basic process of using Q-methodology as a research design for novice researchers.
Sclerosing Perivascular Epithelioid Cell Tumor of the Uterus
Authors: Kundu Reetu , Saha Pradip Kumar , Dey Pranab
Published: April 2023

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal uterine tumor and the histological variant, sclerosing PEComa is exceedingly rare. Sclerosing PEComas preferentially occur in the retroperitoneum and occurrence in the uterine corpus is seldom seen. These tumors pose a diagnostic challenge and need distinction from morphological mimickers such as epithelioid smooth muscle tumors, endometrial stromal sarcoma, and metastatic carcinoma. Accurate diagnosis can be established coupling histomorphology with immunostaining. The distinction from other entities is of prime importance considering the therapeutic and prognostic implications. Herein, we describe a case of uterine sclerosing variant of PEComa with diagnostic difficulties and key to diagnose this entity.
Physical Activity Levels, Motivators and Barriers to Exercise among Men and Women Aged 30 to 50 Years in Rourkela, India
Authors: Aneesh Mitravinda , Mahanta Nirupama
Published: April 2023

Background:

Literature suggests that middle age is a period with increasing sedentary behavior and health risks.

Objective:

We conducted the present study to assess physical activity levels of the adults aged 30–50 years and understand the motivators and barriers to regular physical activity.

Materials and Methods:

A cross-sectional study was conducted among 100 adults aged 30–50 years residing in Rourkela, Odisha. The physical activity levels of the adults were assessed using Bouchard’s Physical Activity Record. Height, weight, and waist circumference of the participants were measured using standard procedures. A self-administered questionnaire was prepared to identify the motivators and barriers to physical activity/exercise behavior.

Results:

Nearly half of the participants were obese, 23.3% were overweight and 28% had a normal body mass index. Based on WC and waist-to-height ratio (WHtR), 84% and 79.3% of the participants had metabolic risk, respectively. Over half of the participants were physically inactive. Predominantly, low-intensity activities (yoga, slow walking) were performed as it was assumed to be sufficient. The main motivators of physical activity/exercise behavior were health scare, health benefits, weight loss, availability of resources at convenient time, and better looks. The chief barriers for exercise behavior were lack of motivation, weather, safety concerns, and lack of time.

Conclusion:

Despite over two-third of participants being overweight/obese, 90% of the physically active participants failed to meet the World Health Organization recommendations. Government, community, and individual participation are imperative to formulate interventions strategies to reduce the barriers to physical activity.
Dyslipidaemia in Sri Lanka
Authors: Matthias Anne Thushara , Ekanayake Ruvan , Arambepola Carukshi
Published: April 2023

Cardiovascular diseases (CVDs) are the leading cause of mortality in South Asia. Although well-recognized as a major risk factor, dyslipidemia in such populations is not well-reviewed. To review the trends in dyslipidemia, phenotypes, underlying causes, treatment modalities, and management gaps in Sri Lanka. A narrative review was undertaken on published literature on dyslipidemia in Sri Lanka from 2000 to 2020, extracted using PubMed, Google Scholar, and locally published literature. Out of the 33 documents reviewed, only a limited number was available on large-scale population-based studies. High prevalence of metabolic syndrome along with moderately high low-density lipoprotein-cholesterol, low high-density lipoprotein-cholesterol, high triglycerides, and high ApoB and Lp(a) concentrations was seen. Familial hypercholesterolemia was an understudied area with a need for a national screening program. With dyslipidemia guidelines limited to the management of special disease groups, there is a chasm between guidelines and practice at present in Sri Lanka. Unlike in primary prevention, prescribing high-dose statins in secondary prevention of CVD has been satisfactory. Treatment gaps are identified, with room for improvements in lipid screening and achieving lipid goals. Considering the substantial burden identified, education of physicians, optimizing lipid testing, and aggressive treatment of lipids are key initiatives toward optimizing management of dyslipidemia.
Effect of nutrition education package on dietary modification and anthropometry among attendees of a noncommunicable disease clinic at a rural primary health-care facility in Delhi
Authors: Katre Rohit , Banerjee Bratati , Lal Panna , Sharma Pragya
Published: April 2023

Context:

The global burden and threat of noncommunicable diseases (NCDs) constitutes a major public health challenge that undermines social and economic development throughout the world. NCDs are one of the leading causes of adult morbidity and mortality globally. The disease burden in India due to NCDs has increased from 30% to 55% between 1990 and 2016.

Aims:

We aimed to assess the effect of nutrition education intervention on dietary awareness, practices, and anthropometry.

Settings and Design:

This design was a facility-based before-and-after intervention study without control.

Materials and Methods:

This study was conducted in five phases: planning and recruitment, preintervention, intervention, washout, and postintervention. Data were collected using a pretested, semi-structured interview schedule under the following heads – personal, sociodemographic, and behavioral risk factors of NCDs. Anthropometric examination included weight, height, waist, and hip circumference measurement.

Statistical Analysis:

Collected data were entered into MS Excel and analyzed using IBM SPSS 25 for descriptive and inferential statistics.

Results:

There was a significant increase in mean score for dietary practices and knowledge regarding different food items in the study group. The mean number of servings of fruits and vegetables increased significantly following intervention in the study group (P = 0.001). Significant change in body mass index before and after intervention was found to be in the age group of >60 years (P = 0.041).

Conclusions:

The study has shown the usefulness of intervention aimed at improving dietary behavior among patients of NCDs. With growing burden, there is a need for such innovative and cost-effective measures for halting the rising burden.

Descriptive statistics and probit regression were used to ascertain the influences of the constituents of political economy using individual's dietary intakes.

Results:

The present study found that, differences in income levels (P < 0.05), residential place of stay (P < 0.05), and access to mass media (P < 0.05) were statistically significant to dietary practices and had major implications for NCDs occurrence. The qualitative outcome revealed that, educational and occupational status of individuals may influence dietary practices. The regression revealed that females are exposed to unhealthy dietary practices by 6.2% points. Moreover, rural dwelling had moderate influence on unhealthy dietary practices (3.3% points) than urban dwelling. Again, professionals, sales, and service categories have 5.8%, 5.7%, and 7.6% points unhealthy practices, respectively.

Introduction:

Most adults who should be screened for dyslipidemia do not undergo lipid testing in low- to middle-income countries due to lack of resources and clinical inertia. Those eligible for statin therapy for cardiovascular disease (CVD) prevention are under treated possibly due to clinical inertia. This study aimed to find out the present lipid screening practices and prescribing of statins for primary prevention in a low- to middle-income country.

Methods:

This study was conducted at medical wards of Colombo South Teaching Hospital in patients with a first-time acute coronary syndrome (ACS), who have not been on treatment with statins and not diagnosed with dyslipidemia prior to this admission. Eligibility for lipid screening was assessed using U.S. preventive services task force recommendations. CVD risk prior to ACS was assessed by QRISK2 score. Lipid profile was done within 24 h.

Results:

Out of 125 participants, 70.4% had a QRISK2 >10 and were eligible for statins prior to their first episode of ACS. Eighty-four percent have not had a lipid screening and 91.4% were not aware of the need for it. 54.4% were not aware that the elevation of certain types of cholesterol leads to ACS. Of 125 patients (100 males/25 females), mean age 55.78 (26–82). Body mass index >23kg/m2 in 65.6%. 65.6% had some lipid abnormality. Total cholesterol >200 in 29.6%, low-density lipoprotein cholesterol >130 in 28.8%, triglyceride >150 in 31.2%, high-density lipoprotein cholesterol suboptimal in 67.2%.

Discussion:

Lipid screening is suboptimal. Most patients who were eligible for statins based on their CVD risk prior to their first episode of ACS, were not receiving statins prior to their first ACS. Patients should have their CVD risk estimated and statins should be given to eligible patients for prevention of ACS.
Exploration of barriers to self-care practices among diabetic patients attending chronic disease clinic in an urban slum

Published: April 2023

Background:

Glycemic control in diabetes can be achieved by adopting self-care practices. It also leads to reduction of complications and improvement in the quality of life. Identification of barriers to adopting these practices can help devise strategies to overcome them. This study was conducted to understand the self-care practices among diabetics and the barriers affecting those practices among diabetics in the urban slum area.

Materials and Methods:

This qualitative study using Focus Group Discussions (FGDs) was conducted in a chronic disease Outpatient clinic in Mumbai, in November 2020. Four FGDs with 32 participants were conducted. Thematic analysis of the transcripts was done.

Results:

Three major themes were identified – living with diabetes, practices to maintain glycemic control, and potential barriers. Barriers for self-care practices were - confusing advice provided by family and doctors, feeling rejected (stigmatized), lack of motivation for exercise, complications of diabetes, lack of family cooperation, lack of knowledge on foot care, physical constraints, nonavailability of medications, lack of social and financial support, suboptimal knowledge regarding diabetes, and misconceptions.

Conclusions:

Motivating diabetic patients for regular physical activity by starting from simple indoor exercises to outdoor exercises are necessary. Counseling the family members on the complications of diabetes due to inappropriate dietary practices should be advocated. Improvement in doctor-patient communication and providing information on the foot care practices is the need of the hour.
Primary epithelial–myoepithelial carcinoma of the lung

Published: April 2023

Epithelial–myoepithelial carcinoma (EMC) of the lung is a rare neoplasm, constituting about 0.1%–1% of all primary lung cancers. EMC usually has an indolent course with occasional distant metastasis. A 52-year-old male presented with an unresectable lesion in the upper lobe of the right lung with mediastinal lymph nodes. Bronchoscopic biopsy and detailed histopathological examination revealed an EMC of the lung. Due to advanced disease and poor performance status of the patient, he was treated with palliative radiation followed by palliative chemotherapy. However, the patient succumbed to the disease after two cycles of palliative chemotherapy. Experience with EMC of the lung is limited and optimal treatment protocols have not been defined, with current treatment mainly extrapolated from EMC of the salivary glands from the head and neck. We add another case to the limited literature of EMC of the lung.
PREDICTION OF PARKING SPACE AVAILABILITY USING ARIMA AND NEURAL NETWORKS

It may be critical for drivers to have information about the occupancy rates of the parking spaces around their destination in order to reduce the traffic density, a non-negligible part of which caused by the trips to find an available parking space. In this study, we predict parking occupancy rates (and thus, space availability) using three different techniques: (i) auto-regressive integrated moving average model, (ii) seasonal auto-regressive integrated moving average model and (iii) neural networks. In the implementation phase, we use the data set of the on-street parking spaces of the well-known “SFpark” project carried out in San Francisco. We take into account not only the past occupancy rates of parking spaces, but also exogenous variables that affect the corresponding occupancy rates as day type and time period of the day. We make predictions with different model structures of each of the considered methods for each parking space with different parking occupancy patterns in the data set and then compare the results to find the best model design for each parking space. We also, evaluate the results in terms of the superiority of the methods over each other and note that the performance of neural networks is better than those of the other approaches in terms of the mean squared errors.

Authors: Santeliz Aristides
Published: April 2023

Este ensayo presenta un breve razonamiento sobre los comienzos de los estudios superiores en el mundo con algo de historia sobre las universidades y de los sistemas educativos y niveles de estudios en el contexto venezolano. El objetivo es contribuir a divulgar iniciativas en espacios educativos para dar a conocer el origen de los estudios superiores en suelo venezolano, a través de un pequeño recorrido por la historia. Tiene un enfoque investigativo documental que busca comunicar los elementos significativos de las raíces de la educación universitaria, para complementar la construcción del significado de la acreditación académica hasta la aparición de las universidades en el mundo. Esta investigación refleja la aceptación en la historia de la humanidad, el antes y después de los estudios superiores en diferentes países; concluyéndose que las antiguas civilizaciones enseñaban o preparaban a estudiantes o discípulos para grados o cargos oficiales antes que aparecieran las universidades.
La modalidad discursiva y la evidencialidad. Una perspectiva para analizar materiales instruccionales
Authors: Rada Blanco Neudys María
Published: April 2023

utilizado en las asignaturas que componen la oferta académica de la Universidad Nacional Abierta (UNA). El presente trabajo tiene como propósito hacer un estudio lingüístico enmarcado en una investigación de campo sobre el discurso académico usado del plan de curso de la asignatura Lengua y comunicación, perteneciente al Área de Estudios Generales, tomando en consideración la modalidad discursiva, los actos de habla y la evidencialidad (Dottori 2019; Sologuren y Venegas; 2022 López, 2005; Alvarado 2017). Se pudo llegar a la conclusión de que en este predomina como modalidad de la enunciación la imperativa y el acto de habla directivo, para establecer las estrategias instruccionales y de evaluación. Además, se pudo constatar que la modalidad epistémica asertiva y la evidencialidad se manifiestan mediante el grado de certeza imputable al saber, con el uso de verbos de conocimiento, de comunicación o presentadores de información.
La voluntad en Kant y Nietzsche: Clave para comprender la acción moral
Authors: Monasterios María Andreina
Published: April 2023

La voluntad es clave para comprender la acción moral. Por ello, conviene examinarla a la luz de la Fundamentación de la metafísica de las costumbres de Kant y La voluntad de poder de Nietzsche. Estas reflexiones presentarán las generalidades del formalismo ético kantiano; contrario al proyecto amoral de Nietzsche, cuyas aspiraciones ponderan el lado natural de los valores. Segundo, mostrará cómo Kant privilegia el uso moral de la razón, determinante de la buena voluntad; a diferencia de Nietzsche, quien sostiene que la razón es un impulso en lucha. Por último, referirá la noción kantiana sobre la voluntad autónoma, facultad de elegir aquello necesario, bueno y conforme al “deber ser”; contrariamente, Nietzsche expresa la voluntad de poder como impulso vital y libre que invita al sujeto a responsabilizarse de su propia ley y transformarla en destino propio. Enfrentar estas posiciones invita al lector a conciliarlas en algún punto.
