Abordaje experimental para la enseñanza y el aprendizaje de la reacción de Maillard en química de los alimentos
Authors: Igartúa Daniela E. , Sceni Paula
Published: September 2023

El color de los alimentos es uno de los primeros atributos percibidos por el consumidor y se lo asocia con el sabor y el estado de conservación. La reacción de Maillard es un proceso complejo que genera colores en la gama del amarillento hasta marrón oscuro, aromas y sabores, característicos de alimentos cocidos que contienen hidratos de carbono y aminoácidos o proteínas. En este trabajo se analizan posibles abordajes experimentales para la enseñanza y el aprendizaje de la reacción de Maillard, basados en la experiencia en la asignatura Química de los Alimentos. El tema se analizó en forma experimental en dos instancias, la primera con un sistema simplificado (muestras en tubos de ensayos) y la segunda en un sistema real (galletitas dulces). Los efectos estudiados fueron el tipo y concentración de azúcar, el pH, el tiempo y la temperatura de cocción. A partir de los sistemas simplificados, se espera que el estudiantado sea capaz de explicar y justificar los resultados observados considerando la teoría. En el sistema real, el propósito es lograr un aprendizaje que le permita al estudiantado explicar fenómenos de su vida cotidiana. Se propone, además, una tercera actividad, donde puedan poner en práctica los conocimientos y habilidades adquiridas, para resolver experimentalmente un problema integrador, con un protocolo no pautado.
La geografía como metaciencia/metaconocimiento para el abordaje de temas de alimentación en la escuela secundaria y en carreras universitarias científico-tecnológicas
Authors: Lampert Damian , Cortizas Ludmila
Published: September 2023

La Didáctica de las Ciencias fue sufriendo a lo largo del tiempo diferentes cambios, entre ellos se incorporaron las llamadas “metaciencias” o “metaconocimientos” en la enseñanza de las Ciencias Naturales, como la sociología, la filosofía, la historia y la epistemología, como parte de la Naturaleza de la Ciencia o Naturaleza de la Ciencia y la Tecnología. En esta línea, la geografía podría también ser una metaciencia para la enseñanza de la química. En este artículo se reflexiona acerca de la geografía como metaciencia para la enseñanza de temas de alimentos, y se presentan resultados y propuestas para su inclusión en la educación química del nivel secundario y universitario. La propuesta se centra en enseñar una química de forma actualizada y contextualizada a las demandas del territorio para fomentar la alfabetización científica, y la formación de una ciudadanía crítica, para el caso del nivel secundario, y para el desarrollo de competencias profesionales acordes a las necesidades actuales, para el caso de carreras universitarias científico-tecnológicas.
Alimentos: de la quimiofobia a la quimiofilia
Authors: López Munguía Agustín
Published: September 2023

La alimentación y la industria alimentaria no han sido ajenos a los grandes avances en el conocimiento científico y la capacidad de plasmarlo en muy diversas aplicaciones. Tales avances incluyen aspectos de la ciencia de alimentos en su relación con la nutrición, la producción y transformación de alimentos, así como su impacto en la cultura y los hábitos alimentarios. Sin embargo, diversos avances en materia de la química de alimentos, se han abordado con poco entusiasmo; peor aún, se ha encontrado en la química una referencia al origen de muy diversos problemas relacionados con la salud y la seguridad alimentaria, siendo los químicos y a la industria de alimentos que los promueve, los responsables de muchos males que nos aquejan. Esta postura, esencia de la Quimiofobia, es abordada de muchas formas y desde muy diversos espacios de comunicación, en los que prevalece la opinión de activistas, fundamentalistas e incluso promotores de modas y productos alimentarios diversos. Es necesario que los químicos, vía la comunicación racional de la química de alimentos, contribuyan a crear un espacio en el que reivindiquemos la riqueza que hoy aporta el conocimiento de la química y de la química que comemos.

Arquivos contestados em contexto intranacional Em torno do caso da Região Autónoma da Madeira (Portugal)
Authors: Ascensão de Macedo L. S.
Published: September 2023

O artigo discute o fenómeno dos «arquivos deslocados», um dos problemas mais complexos da arquivística contemporânea. Embora os casos internacionais tenham sido bem estudados, o objetivo deste artigo consiste em analisar um caso subnacional, menos abordado na produção científica a partir da representação destes arquivos em instrumentos de acesso à informação. O artigo concentra-se num caso específico de disputa de custódia de arquivos entre a Região Autónoma da Madeira (ABM) e o Arquivo Nacional da Torre do Tombo (ANTT) em Portugal. Metodologicamente, este artigo carateriza-se por uma investigação qualitativa. A pesquisa utilizou fontes documentais e arquivísticas para explorar estratégias de representação de conjuntos documentais em disputa, com base em dados sobre a representação do conteúdo em instrumentos de acesso à informação publicados pelo ANTT e pelo ABM. Os resultados apontam para o facto de as entidades custodiantes não terem envidado esforços para alcançar uma representação da informação técnica e cientificamente reunificada. O estudo recomenda a concessão de novas garantias literárias para a descrição de conjuntos documentais deslocados que potenciem a sua reunificação.

Published: September 2023

A ocorrência de doenças diarreicas agudas, além de ser uma importante questão de saúde pública, está relacionada a diversos fatores, dentre os quais podem-se destacar as condições de saneamento básico, bem como aspectos socioeconômicos das localidades de sua incidência. O objetivo deste artigo é realizar estudo comparativo entre indicadores de saneamento básico e socioeconômicos e a incidência de doenças diarreicas agudas nos estados da Amazônia Oriental brasileira. Os dados utilizados são de caráter secundário, obtidos a partir de pesquisa bibliográfica e documental, entre os anos de 2010 a 2019, em bancos de dados oficiais, utilizando-se da estatística descritiva e análise de correlação, para o tratamento de dados obtidos, com o auxílio do software Minitab 18. Entre as médias anuais de ocorrências de doenças diarreicas agudas, destacam-se os estados do Pará e Maranhão, que apresentaram médias de aproximadamente 217.000 e 128.500 casos, respectivamente. O esgotamento sanitário foi maior para o estado do Mato Grosso, com 26%, seguido do Tocantins com 19%, enquanto o Amapá e o Pará apresentaram os menores indicadores de prestação do serviço, ambos com 5% de atendimento para o período. Esse contexto também não apresentou mudanças significativas nos últimos 10 anos, refletindo-se na manutenção e pouca variação na ocorrência de doenças diarreicas agudas. Os indicadores de saneamento, nem sempre acompanham em quantidade e qualidade o crescimento populacional, refletindo no aumento na ocorrência de DDAs, as quais são consideradas evitáveis mediante medidas sanitárias adequadas.
Hybrid Encryption using LSB steganography and RSA
Authors: M Vineela Reddy , G Anudeep Reddy
Published: September 2023

Abstract: In the present world of communication, computers and the internet are the major media that connects different parts of the world as one global virtual world. So we can easily exchange lots of information within seconds of time, but the confidential data that needs to be transferred should be kept confidential. Thus, in order to aid this, we have proposed a new encryption technique by combining Image steganography (LSB) with the cryptographic RSA algorithm for providing more security to our data as well as imperceptibility. The expected outcome would be a properly secure combination of encryption models that uses steganography to hide the message content in a cover image, and also encrypts the message using the cryptographic algorithm, as an additional security layer, in case the content was retrieved from the cover image.

Authors: Espinosa Jovel Camilo , Agudelo Valencia Paula , Torres Urazán Daniela
Published: September 2023

Introducción: los síntomas neuropsicológicos son una preocupación importante para los pacientes con epilepsia y pueden llegar a ser muy influyentes en la percepción de calidad de vida. En el caso de la epilepsia del lóbulo temporal, existen muchas variables que influyen en el desempeño cognitivo de los pacientes, entre las más importantes se encuentran la etiología, la edad de inicio, la duración de la enfermedad y la frecuencia de crisis; sin embargo, una de las variables más importantes es la lateralidad de la epilepsia. Está claramente demostrado que los síntomas cognitivos de la epilepsia del lóbulo temporal varían en función del hemisferio cerebral afectado.
Contenido: la epilepsia del lóbulo temporal es una de las principales epilepsias focales que es susceptible de manejo quirúrgico, y, en este sentido, el tipo de procedimiento también tiene una gran importancia en el desenlace cognitivo de estos pacientes. En este artículo, realizamos una revisión narrativa de la literatura, con el objetivo de describir el riesgo neuropsicológico relacionado no solamente con la epilepsia del lóbulo temporal per se, sino también con las intervenciones quirúrgicas que se realizan en pacientes refractarios a la medicación.
Conclusiones: es importante conocer los conceptos sobre las implicaciones del impacto cognitivo en los pacientes con epilepsia del lóbulo temporal antes de tomar decisiones quirúrgicas en pacientes refractarios, así como entender que el tipo de cirugía también influye en su desempeño cognitivo. Se debe buscar un equilibrio entre la libertad de crisis y las posibles secuelas neuropsicológicas posquirúrgicas.

O uso da máscara causou impacto na qualidade vocal. A pandemia interrompeu a relação entre paciente-terapeuta e impactou negativamente a manutenção dos hábitos de saúde vocal.
The Effect of Debt-to-Equity Ratio, Return on Asset, Current Ratio, and Total Asset Turnover on Stock Price: The Intervening Effect of Intrinsic Value in Indonesia’s Retail Business
Authors: Nurwulandari Andini , Wahid Ririan Safiadi
Published: September 2023

This study examines the effect of Debt-to-Equity Ratio (DER), return on assets (ROA), current ratio (CR), and total asset turnover (TATO) on stock prices with their Intrinsic Value as intervening variables in retail companies in Indonesia. Data regarding retail companies were obtained from the Indonesia Stock Exchange, and secondary data on these companies' financial ratios were collected from Stockbit. Stock price data were sourced from Yahoo Finance, and the intrinsic value of shares was determined using the price-to-earning ratio method. Drawing on structural equation modeling, the findings demonstrate that DER and ROA exert a positive and statistically significant effect on intrinsic value. TATO, on the other hand, exhibits a negative and statistically significant effect on intrinsic value, while CR demonstrates a negative and non-significant effect. Regarding stock prices, DER and CR have a negative and statistically significant effect, while ROA and Intrinsic Value have a positive and statistically significant effect. TATO, however, shows a negative and non-significant effect on stock prices. Furthermore, DER has a positive and non-significant effect on stock prices through intrinsic value, whereas ROA has a positive and statistically significant effect on stock prices through intrinsic value. CR, on the other hand, exhibits a negative and non-significant effect on stock prices through intrinsic value, and TATO demonstrates a negative and statistically significant effect on stock prices through intrinsic value.

Authors: Herweg Bengt , Welter-Frost Allan , Noujaim Sami , Cook Christopher J. , Mencer Nicholas , Wilson David R. , Kotch Nick , Kharod Anant , Olshansky Brian
Published: September 2023

Introduction: Inappropriate sinus tachycardia (IST), a clinical syndrome
with distressing symptoms, is characterized by paroxysmal or persistent
sinus tachycardia in the absence of any identifiable primary etiology.
Sinus node modification is not first line therapy given frequent
recurrence and high complication rates. While medical therapy may be
effective, symptoms frequently persist. Our objective is to describe the
range of arrhythmias encountered during ablation in a cohort of IST
patients refractory to medical therapy and to further the understanding
of the etiology and mechanism of IST. Methods: We present a
retrospective review of 33 patients who underwent sinus node
modification for the treatment of therapy-refractory IST. Results:
Arrhythmias included IST in 33 patients (100%), atrial tachycardia or
frequent premature atrial contractions in 16 patients (48%), atrial
fibrillation in 7 patients (21%), typical and atypical atrial flutter
in 13 (39%) and 2 patients (6%), respectively, Wolff-Parkinson-White
syndrome in 3 patients (9%), AV nodal reentry tachycardia in 3 patients
(9%), and ventricular tachycardia or premature ventricular contractions
in 4 patients (12%). Accelerated atrioventricular junctional (AVJ)
tachycardia was present in 7/33 patients (21%), was refractory to
medical therapy and caused disabling symptoms in all seven patients.
Patients with AVJ tachycardia required extensive ablation at multiple
sites, and 3/7 patients became pacemaker dependent. Conclusion: In
patients undergoing SAN modification for IST, multiple arrhythmias were
encountered. Accelerated AVJ tachycardia was frequently encountered and
required extensive ablation of up-regulated tissue in the AVJ to improve
symptoms. Thus, the pathologic process underlying IST may not be limited
to the sinus node.
Colder ambient temperatures constrain female mate preference for ornamental traits

Published: September 2023

Male ornamentation is usually costly and may show trades-offs with other
life-history traits such as paternal care, which can subsequently affect
female preference. Studies on female mate choice have mostly examined
how mate-choice cues differ in their expression or ability to be
detected in different environmental contexts. However, less focus has
been placed on examining how external forces affect female preferences.
The purpose of this study was to explore how parental investment
strategy and mate choice were mediated by ambient temperature.
Specifically, we examined how male ornamentation characteristics and
subsequent female incubation investment were impacted by ambient
temperature in four plover populations that were breeding across an
environmental gradient. We discovered that larger males had more
ornamented plumage in warmer conditions, and they were favored by larger
females who invested an elevated time into incubation. In contrast, in
cooler conditions, males’ body size and the color of their ornaments
were inversely associated, and females showed weak preference for males
with more colorful ornaments. These results imply that female preference
for male ornament can change in response to ambient temperature and
demonstrate that female preference for male ornamentation may be limited
in harsher conditions with higher parental care expenses.
A numerical study of the transient natural convective heat transfer from thin, horizontal, isothermal plates of simple and complex shapes under turbulent flow conditions
Authors: Bandyopadhyay Koustav , Oosthuizen Patrick
Published: September 2023

Natural convective heat transfer finds importance in applications such
as cooling of low power electronics, Printed Circuit Boards (PCBs) and
of components in a restricted space. The variable load on such
components also warrants the study of transient behaviour. In this
investigation, unsteady natural convection was numerically computed
around thin horizontal flat isothermal plates of different shapes using
commercial CFD solver Ansys FLUENT. The plates were maintained at 400K
and exposed to air at ambient temperature of 300K. Boussinesq
approximation was adopted. Transient heat transfer from the top and
bottom surface of the plates were presented in terms of the Nusselt
number, Rayleigh number and dimensionless time, calculated using two
length scales- 4*Total Area/Total Perimeter and square root area of
single side surface area. Rayleigh numbers between 10
-10 were considered. Analysis of
the transient heat transfer profiles, calculated using the two length
scales revealed that plate shapes had more pronounced effect on the heat
transfer process compared to the length scale. Prior to reaching the
steady state, the Nusselt number profile undergoes transition from
initial conductive phase to convective flow development. Increasing the
Rayleigh number tends to shorten the conduction and convective flow
development phases. Further investigation revealed that unlike in
laminar flow regime, the heat transfer in turbulent regime is
significantly affected by fluid flow pattern, influenced by plate shape.
Normalized Nusselt number was used to incorporate this shape effect,
which enabled obtaining a singular transient heat transfer variation
independent of plate shape and size. These profiles would assist the
designers to compute the complete transient natural convective heat
transfer characteristics of any plate shape using only the steady state
heat transfer value.
A machine learning parameterization of clouds in a coarse-resolution climate model for unbiased radiation

Published: September 2023

Coarse-grid weather and climate models rely particularly on
parameterizations of cloud fields, and coarse-grained cloud fields from
a fine-grid reference model are a natural target for a machine-learned
parameterization. We machine-learn the coarsened-fine cloud properties
as a function of coarse-grid model state in each grid cell of NOAA’s
FV3GFS global atmosphere model with 200 km grid spacing, trained using a
3 km fine-grid reference simulation with a modified version of FV3GFS.
The ML outputs are coarsened fine fractional cloud cover and liquid and
ice cloud condensate mixing ratios, and the inputs are coarse model
temperature, pressure, relative humidity, and ice cloud condensate. The
predicted fields are skillful and unbiased, but somewhat
under-dispersed, resulting in too many partially-cloudy model columns.
When the predicted fields are applied diagnostically (offline) in
FV3GFS’s radiation scheme, they lead to small biases in global-mean
top-of-atmosphere (TOA) and surface radiative fluxes. An unbiased global
mean TOA net radiative flux is obtained by setting to zero any predicted
cloud with grid cell mean cloud fraction less than a threshold of 6.5%;
this does not significantly degrade the ML prediction of cloud
properties. The diagnostic, ML-derived radiative fluxes are  far more
accurate than those obtained with the existing cloud parameterization in
the nudged coarse-grid model, as they leverage the accuracy of the
fine-grid reference simulation’s cloud properties.
Towards the Development of an Enhanced Certificate Verification System for West African Institutions
Authors:   Department of Computer Science National Open University of Nigeria Abuja, Nigeria, Nwaocha Vivian, O , Oloyede Ayodele
Published: September 2023

The current approach adopted for certificate verification in Nigeria and most West African countries rely on paper-based documentation, which makes the process extremely unreliable and clumsy, as employers need to contact the issuer of a certificate to confirm that the award is legitimate and up to date. Several researchers and vendors have come up with different approaches to using blockchain technology. However, preliminary surveys reveal that the adoption of blockchain technology could be hindered by an inadequate power supply, poor ICT infrastructure as well as poor funding. Therefore, this research explores the enhancement of the current solution to guarantee credibility and sustainability. Thus, this research seeks to propose an enhanced certificate verification system for higher educational institutions in West Africa.

Intelligence services are inherently leery of books written by former employees, but here, both Leijonhielm and Swedish intelligence come out relatively well.
East Central Europe and Communism: Politics, Culture and Society 1943–1991
Authors: Oldberg Ingmar
Published: September 2023

Trots titeln East Central Europe and Communism: Politics, Culture and Society 1943–1991 täcker denna bok alla eight Östeuropas tidigare kommunistiska länder, inklusive »vildarna» Jugoslavien och Albanien som inte kontrollerades av Moskva. I varje land granskar Ramet kronologiskt kommunisternas politik och maktkamp, ekonomiska konsekvenser som industrialisering och jordbrukskollektivisering, men inte minst politikens effekter inom kultursfären, inklusive kyrkorna, samt kvinnornas ställning, vilka är viktiga men ofta försummade ämnen. Hon konkluderar med funktionalisten Robert Mertons terminologi att det kommunistiska systemet inte fungerade i något land med växande missnöje och opposition som icke avsedda eller insedda följder. 
Despite its title, East Central Europe and Communism: Politics, Culture and Society 1943–1991, this book covers all eight ex-Communist states in Eastern Europe, including the mavericks Yugoslavia and Albania, which were not controlled by Moscow. Ramet chronologically analyses the communist policies and power struggles in each country, and consequences such as industrialization and collectivisation of agriculture. Not least, she looks at effects in the cultural sphere, including the churches, and the changing situation for women. Ramet concludes, using the sociologist Robert Merton's terminology, that the communist system did not work in any of these countries, and growing disaffection and opposition are among the unintended and actual results.

Published: September 2023

Este estudo objetivou evidenciar as conformidades e inconsistências de natureza social e ambiental praticadas pelas empresas de energia, com base na relação dos 11 critérios e da NBC T 15 do estudo de Cruz et al. (2019). Quanto a metodologia, esta foi classificada como qualitativa, documental, e, descritiva. O estudo constatou que as empresas apontam ações positivas em relação ao meio ambiente, essas evidências foram detectadas através dos gastos com preservação do meio ambiente, provisão para danos que possam ocorrer, investimentos com gastos em educação ambiental para a comunidade externa, apresentação de informações comparativas com os anos anteriores, apresentação de metas futuras na área ambiental e ações ambientais voltadas para o público externo. No entanto, essas ações não foram identificadas para o público interno. O estudo concluiu que as empresas praticam ações ambientais, sendo que a EDP Engie do Brasil é a empresa que mais investe em startups de projetos nessa área, e a empresa Light foi a que mais gerou informação de suas práticas ambientais. Esses achados corroboraram com o estudo de Pletsch et al. (2015), em que os autores evidenciaram, em sua pesquisa, que a maioria das empresas possui política ambiental estruturada.

Published: September 2023

Este artigo objetiva analisar a evolução do perfil da estrutura mínima de governança das Entidades Fechadas de Previdência Complementar (EFP). Aplicaram-se as técnicas de pesquisa quantitativa documental, com amostra de 280 entidades brasileiras, representando 93,02% da população, com dados segregados em dois períodos: (2013-2017) e (2018-2022). As variáveis qualitativas foram analisadas por meio de frequência relativa, considerando dois períodos; e teste de associação. Os resultados indicaram presença, embora minoritária, de profissionais com baixo nível de escolaridade; e predominância de homens na ocupação dos cargos, principalmente para gestão de recursos financeiros e dirigentes máximos de diretoria. A evolução evidencia redução da quantidade de gestores, como possível consequência da concentração de entidades multipatrocinadas; crescimento da participação feminina; ampliação da influência das patrocinadoras no Conselho Deliberativo e dos participantes no Conselho Fiscal. Os resultados ratificam a importância dos princípios e práticas de governança corporativa para subsidiar a mitigação dos riscos de competência técnica, de conflitos de interesses, e de desigualdade de gênero.
Practical implications of measuring at historical cost in an inflationary environment
Authors: Grecco Marta Cristina Pelucio , Silva Elisson Paulo , Geron Cecília Moraes Santostaso , Silva Fabiana Lopes da
Published: September 2023

This study aimed to analyze the impacts that can occur in the balance sheets of companies in inflationary environments when these balances sheets are not corrected, independently of whether the inflation rate reaches the level determined by IAS 29. The sample chosen consisted of companies from G20 member states that had already adhered to IFRS. The data distribution was analyzed using the ROA, ROE, EPS, and revenue weighted by total assets of the companies studied, before and after monetary correction, using statistical inference and evaluating the statistical probability distribution using the Kolmogorov-Smirnov and Shapiro-Wilk normality tests, and subsequently applying the Wilcoxon non-parametric test. The main results found were that monetary correction in the financial statements of the companies analyzed shows significance, both in countries with high inflation rates and in those with lower cumulative inflation rates. It is concluded that inflation significantly impacts the results of financial statements above a 10% cumulative rate, so measuring accounting elements at historical cost loses relevance, and it is vital to use corrected historical cost by applying a monetary correction.

Authors: Trindade Polyanne Cruz Soares Silva da , Felix Ynes da Silva
Published: September 2023

Compreendendo a necessidade de respeitar parâmetros mínimos da dignidade da pessoa humana nas relações empregatícias e implementar os direitos sociais, a ONU reconheceu que a empresa, por deter poder econômico significativo, como contrapartida e em razão da função social que exerce, está obrigada a respeitar os direitos humanos. Nesse sentido aprovou, em 2011, uma recomendação contendo os princípios orientadores das Nações Unidas sobre empresas e direitos humanos, cujos pilares são proteger, respeitar e reparar. Considerando que, dentre as finalidades do compliance trabalhista está à manutenção de todos os aspectos trabalhistas dentro da legalidade, após descrever de forma singela a respeito do surgimento do programa, a presente pesquisa busca analisar a utilização da ferramenta due diligence em direitos humanos, que é um procedimento de investigação jurídica, observando os princípios orientadores da ONU, em específico o de número 17.O estudo possui caráter descritivo e exploratório, sendo o método dedutivo, recorrendo, para tanto, aos tipos de pesquisa bibliográfico e documental, a partir de uma revisão de livros, artigos, periódicos, documentos de organizações especializadas e normas nacionais e internacionais sobre a problemática proposta.

A digital environment produces new concepts and understanding of language learning and teaching. Students are encouraged to be able to manage their goals and learning process independently. However, the success of self-regulated learning (SRL) in the digital era depends on the student's ability to explore the latest technology, which is defined as digital and information literacy. The problem comes when the use of higher technology unbalances students' digital and information literacy levels. Therefore, this research examined digital and information literacy skills as a base for ELF self-regulated learning. The researcher designed quantitative research. The questionnaires were distributed to 70 respondents from EFL students at the Department of English, Universitas Negeri Malang. Questionnaire data were analyzed using descriptive statistics to find digital literacy skills. The result showed that the students have a high level of digital literacy. There are underlying factors affecting their decisions and preferences that were explicated in the questionnaire responses, such as intake year, study load, and motivation. The findings about students' digital literacy can support teachers in planning interactive digital language learning. At the higher education level, there should be more practice and monitoring of collaborative learning activities.

Academic dishonesty/misconduct has been one of the major issues in Malaysia which is widespread in the higher learning institutions. It implies any type of fraudulent act among students such as paying another person to do the task, purchasing a class research paper, getting test questions before the date of an examination, or duplicating the finished work of another student that applies to formal academic exercises. This cross-sectional study was conducted to determine the practice of academic dishonesty among postgraduate students in the Faculty of Health Sciences, UKM KL. The McCabe Academic Integrity Questionnaire was adopted and distributed to the respondents. Results show that there is a low frequency of academic dishonesty involved among research and coursework postgraduate students and there are no significant differences between both modes of the study. Age and gender show a significant correlation with academic dishonesty practices among all four demographic factors studied.

During the critical COVID-19 pandemic period, many governments, including the Malaysian government, imposed domestic and international travel bans. People were discouraged from travelling due to safety and regulations. The hotel industry was severely affected by the COVID-19 pandemic, and the government decision impacted the nature of hospitality services. Customers interacted face-to-face with hotel employees, thus increasing the possibility of being infected as the virus is primarily transmitted between human respiratory droplets and physical contact routes. Many hotels focused on improving their safety techniques and implementing risk-reduction strategies to encourage customers to visit their hotels. Some strategies include adopting technology innovation to minimise guest contact with hotel employees (e.g., contactless check-in and check-out) and improving cleanliness to minimise health risks (e.g., regularly sanitising hotel rooms and public areas). This study investigated the influence of technology innovation adoption on customers' perceived health risks and customers’ hotel selection behaviour during the pandemic period in Malaysia. An online self-reported questionnaire was developed and conveniently distributed via social media platforms between December 2021 to February 2022. The data obtained showed that 420 individuals were interested in staying at four- or five-star hotels in Kuala Lumpur, Malaysia. Most of the respondents have had their second and third doses of vaccination. Based on the analysis, this study found that the adoption of technology innovation significantly influenced customer-perceived health risk and hotel selection behaviour. Findings from this study will benefit many stakeholders, such as hotel operators, and help them understand the influence of technology-based services on customer behaviour and in considering whether to invest in technology to maximise their businesses.

Financial statement fraud is a serious issue that can lead to far-reaching consequences for businesses, investors, and the economy. To better understand this issue, this study tries to examine the progress of research publications on financial statement fraud by analyzing data obtained from the Scopus database between 2003 and 2022. Descriptive bibliometric analysis was utilized to generate a bibliometric tabulation of research publications focused on significant financial statement fraud research. The analysis involved identifying patterns in research publications to determine the publication year, top authors, citation count, types of studies, journal sources, publishers, institutions, countries, and document types. By utilizing scientific quantitative analysis and statistics, this study will provide some valuable insights that help bridge the gap using bibliometric analysis. Additionally, it could improve the understanding of financial statement fraud for future research and facilitate the creation of a research agenda for academic scholars.

Air yang menenuhi kriteria kualitas air yang bersih menjadi salah satu standar kualitas hidup masyarakat banyak. Akan tetapi seiring dengan berkembangnya zaman, ketersediaan air yang memenuhi kualitas sangat sulit ditemukan. Masyarakat Kecamatan Sukun yang mengakses air yang sudah terjamin bersih masih sangat minim. Penyakit diare menjadi penyakit berbasis lingkungan yang disebabkan oleh konsumsi air yang yang paling banyak terjadi di Kecamatan Sukun. Penelitian ini bertujuan untuk mengetahui keterkaitan antara kualitas air tanah dangkal dengan tingkat risiko terkena penyakit pada masyarakat di Kecamatan Sukun Kota Malang. Kualitas air tanah dianalisis dengan menggunakan metode Water Quality Index. Tingkat risiko terkena penyakit dianalisis dengan metode Quantitative Microbiological Risk Assessment. Sedangkan untuk mengetahui keterkaitannya menggunakan uji korelasi Pearson Product Moment. Hasil dari penelitian menunjukkan parameter E. coli tergolong cukup tinggi, sedangkan untuk parameter pH, TDS dan suhu tergolong dalam kategori aman. Nilai indeks kualitas air berada pada kategori cukup, baik, dan sangat baik. Tingkat risiko terkena penyakit diare pada masyarakat tergolong tinggi. Keterkaitan antara kualitas air tanah dengan tingkat risiko terkena penyakit di lokasi penelitian tergolong dalam hubungan kuat negatif. Tingkat risiko terkena penyakit diare pada masyarakat tergolong tinggi, akan tetapi fakta di lapangan menujukkan bahwa masyarakat rata-rata tidak mengalami gangguan kesehatan khususnya diare. Hal ini disebabkan karena masyarakat menerapkan perilaku hidup bersih dan sehat dengan baik.
