Published: June 2022

Se estudiaron algunos parámetros poblacionales de Liomys pictus en tres áreas del bosque tropical subcaducifolio con diferente tiempo de regeneración: 1) bosque tropical subcaducifolio (BTS), 2) vegetación secundaria con 32 años de regeneración (VS32) y 3) vegetación secundaria con 7 años de regeneración (VS7). El ciclo anual se dividió en tres temporadas climáticas con base en datos de precipitación y temperatura registradas en el área de estudio: seca-cálida (febrero-mayo), seca-fría (octubre-enero) y lluvias (junio- septiembre). Los muestreos se realizaron en cuadrantes, dos en BTS (C1, C2), dos en VS32 (C3, C4) y uno en VS7 (C5), usando la técnica de captura-recaptura. La densidad (ind/ha) se calculó mediante el método de Jolly- Saber. Durante la temporada seca-cálida se presentó diferencia significativa en el número de capturas totales y recapturas entre los cuadrantes, así como en la densidad, siendo el C5 diferente (P < 0.05), del resto de los cuadrantes. Los individuos juveniles fueron registrados principalmente al inicio de la temporada de lluvias en los cinco cuadrantes. Solo el número de hembras adultas fue diferente significativamente entre los cuadrantes durante la temporada seca-cálida, siendo el C5 diferente de los restantes (P < 0.05). La proporción de sexos fue de 1:1 en C1, C3 y C4 (P> 0.05), de 1:0.5 en C2 (P< 0.05) y de 0.5:1 en C5 (P< 0.05). El registro de actividad reproductiva fue mayor en machos que en hembras, en ambos casos en el C5 se registró la mayor actividad. Menos del 40% (n=116) en los cuadrantes C1, C2, C3 y C4 y el 60% (n=56) en C5, de los machos adultos capturados estuvieron activos reproductivamente, presentando la mayor actividad en la estación seca-fría. En hembras, menos del 20% (n=51) en C1, C2, C3 y C4 y el 20% (n=25) en C5, fueron activas reproductivamente, esta actividad se concentró entre las temporadas seca-cálida y al principio de la temporada de lluvias. Se observó mayor estabilidad poblacional en el cuadrante de VS7, ya que el número de individuos recapturados fue mayor, así como la longevidad y la residencia de hembras. Fue clara la diferencia en algunos de los parámetros poblacionales de L. pictus en el cuadrante de VS7 con respecto a los cuadrantes de BTS y de VS32.
DISTRIBUCIÓN DE ROEDORES RESERVORIOS DEL VIRUS CAUSANTE DEL SÍNDROME PULMONAR POR HANTAVIRUS Y REGIONES DE POSIBLE RIESGO EN MÉXICO
Authors: Sánchez Cordero Víctor , Peterson A. T. , Martínez Meyer Enrique , Flores Rita
Published: June 2022

Se determinó la distribución geográfica de los roedores identificados como reservorios del virus Sin Nombre y otros posibles hantavirus en México, causante del síndrome pulmonar por hantavirus (SPH). Ante la ausencia de casos de SPH documentados en México, este estudio pretende identificar posibles regiones de riesgo, considerando la distribución geográfica de los roedores reservorios. Se modeló el nicho ecológico de las especies de roedores reservorios del virus, y se proyectó en mapas para estimar distribuciones potenciales, usando localidades de colecta, mapas ambientales digitales, el algoritmo genético de cómputo GARP (Genetic Algorithm for Rule-set Prediction, por sus siglas en inglés) y un sistema de información geográfico. Se incluyeron distribuciones potenciales de tres especies conocidas como reservorios importantes de hantavirus en Estados Unidos, cuatro especies de roedores que se consideran reservorios potenciales del virus en México y de todas las demás especies del género Peromyscus. Las localidades geográficas de los casos de SPH detectados en humanos en los Estados Unidos coincidieron de forma significativamente mayor que en un modelo al azar, con las distribuciones potenciales de los tres roedores reservorios. En México, los roedores reservorios y los roedores potencialmente reservorios, cubren extensas zonas geográficas, identificándose amplias regiones de posible riesgo de transmisión de hantavirus. La población potencialmente expuesta a la infección, considerando las características de vivienda rural y la distribución potencial de especies de roedores reservorios del virus, se estimó entre 650,000 y 1’750,000 personas. La coincidencia geográfica significativa entre la distribución de roedores reservorios con los casos de SPH reportados en los Estados Unidos, sugiere que la distribución de los roedores reservorios se correlaciona con áreas de riesgo de SPH. Ante la similitud entre México y las regiones de riesgo en los Estados Unidos respecto a sus condiciones biológicas, ecológicas y sociales propicias para la transmisión de SPH, predecimos que (1) en México se detectarán casos de SPH en amplias zonas geográficas, las cuales coinciden con las distribuciones de roedores reservorios y, (2) se va a registrar una mayor tasa de transmisión de SPH en México que en los Estados Unidos.

Published: June 2022

El presente trabajo tuvo como objetivo analizar las diferencias morfológicas entre mamíferos, aves y batracios, por lo que se realizó una comparación de la trompa de Eustaquio (TE) en tres especies animales diferentes: cobayo, gallo doméstico y rana. Para el estudio se utilizaron 30 cabezas (10 por especie) de los animales antes mencionados. Se determinó que en estas tres especies la TE está adaptada al hábitat, en el caso de los cobayos los torus tubarios se encuentran en la rinofaringe, en las aves se encuentra un torus tubario (que se bifurca hacia el oído medio) en el techo de la cavidad oral y en las ranas está en la porción lateral de la orofaringe y está permanentemente abierto. La trompa difiere en tamaño y forma en las diferentes especies.
Movilidad y especialización ecológica como variables que afectan la abundancia y distribución de lepidópteros papilionidos en el sumidero, Chiapas, México
Authors: Molina-Martínez Arcángel , León-Cortés Jorge Leonel
Published: June 2022

Este trabajo explora los patrones de distribución y abundancia de la Familia Papilionidae en un paisaje fragmentado del Sur de México. Basado en la ejecución de transectos fijos distribuidos de forma estratificada en un paisaje heterogéneo, se cuantificaron las asociaciones especie-hábitat y abundancias locales por hábitat para las especies de la comunidad de Papilionidae. Relacionamos los datos de abundancia y ocupación local con datos de distribución nacional, movilidad y especialización ecológica (obtenidos a partir de la consulta a los especímenes depositados o referidos en colecciones entomológicas nacionales y datos publicados) para las especies de Papilionidae registradas en San Fernando, Chiapas. Se ejecutaron un total de 1,319 transectos, durante 18 meses de muestreo entre 2001 y 2002. Durante este periodo se registraron 15 especies de Papilionidae, aunque la información sobre datos de distribución nacional y regional registrados para el grupo sugieren que cuatro especies más (Battus ingenuus, Parides erithalion, Parides photinus y Mimoides thymbraeus) podrían registrarse en el paisaje de estudio. La abundancia local ejerció un efecto positivo sobre la distribución local (r2=0.925 y P=0.001). La especialización ecológica ejerció un efecto significativo sobre la distribución nacional (r2=0.510, P=0.030), pero no sobre la distribución local (r2=0.409, P=0.092). En contraste, la movilidad no ejerció influencia alguna sobre la distribución nacional o local ni sobre la abundancia local (r2=0.307, P=0.216; r2=0.100, P=0.692 y r2=0.046 P=0.857 respectivamente). En tanto, no se identificó una relación significativa entre la distribución local y la distribución nacional de las especies (r2=0.313 y P=0.256). Los patrones de distribución-abundancia reconocidos para la comunidad de Papilionidae en San Fernando son comparables con lo citado para otros taxones en otras regiones del mundo. Sin embargo, el efecto de la especialización ecológica y la movilidad sobre la distribución y abundancia es poco claro y puede ser el resultado de un efecto combinado entre la percepción de las especies y la estructura y composición del paisaje actual. El paisaje fragmentado actual puede afectar la distribución de los recursos y áreas de reproducción de los Papilionidae, y con ello modificar la percepción de las especies –aun las móviles y relativamente comunes, respecto de aquellas especies que ocurren en sitios relativamente conservados.

VARIACIÓN TEMPORAL DE LA ABUNDANCIA EN FAMILIAS DE MOSCAS CARROÑERAS (DIPTERA, CALYPTRATAE) EN UN VALLE ANDINO ANTROPIZADO DE COLOMBIA
Authors: Amat Eduardo , Ramírez-Mora Manuel A. , Buenaventura Eliana , Gómez-Piñerez Luz Miryam
Published: June 2022

Estudios sobre el ensamblaje de moscas descomponedoras en regiones templadas, registran a las familias Calliphoridae, Sarcophagidae, Muscidae y Fanniidae como las más importantes de acuerdo con su abundancia. Se estudia la variación mensual de la abundancia de las familias mencionadas en el ensamblaje de moscas carroñeras del Valle del Aburrá, departamento de Antioquia. Se realizaron dos muestreos mensuales durante un año, utilizando trampas Van Someren-Rydon cebadas con vísceras de pollo y cabeza de pescado en los 4 puntos cardinales y cada uno con diferente vocación de uso. Se encontró un total de 33834 moscas, Calliphoridae (39%), Sarcophagidae (23%), Fanniidae (18%), Muscidae (16%), otras familias (4%). La tendencia de sus frecuencias se mantuvo a través del año excepto en marzo, mayo y agosto donde la familia más abundante fue Sarcophagidae; se destaca la alternancia semestral de la abundancia de Muscidae y Fanniidae durante el año. No se evidencian diferencias significativas de abundancia entre época climática, ni entre las localidades de muestreo y sí por mes de muestreo en donde se evidencia un comportamiento creciente, se encontraron diferencias significativas según la familia siendo Calliphoridae la más frecuente. La proporción acumulada de la familia Sarcophagidae durante el año contrasta con los resultados de otros estudios en ambientes tropicales donde la familia Muscidae es la segunda más frecuente; esta variación podría deberse al tipo diferente de cebo utilizado y a su estado de descomposición.

Published: June 2022

Los humedales costeros e interiores de México son un hábitat importante para las aves. La pérdida y degradación de los humedales, ha sido una de las principales amenazas para la avifauna. En la actualidad se desconoce el número de individuos de las especies de aves que se encuentran en la mayoría de los humedales. Considerando lo anterior, el objetivo de este trabajo fue determinar la diversidad y abundancia de aves en un humedal del norte de Veracruz, el manglar de Tumilco, en Tuxpan. Se utilizó el método de muestreo a distancia y la observación directa para determinar la diversidad y abundancia del total de aves presentes en el manglar. En total se realizaron 63 muestreos con 386 horas efectivas de esfuerzo, llevándose a cabo 274 transectos lineales con longitud de 1 km, en toda el área de estudio. Se registraron 56 especies de aves pertenecientes a 23 familias. Se observaron seis especies que se encuentran dentro de la NOM-059-SEMARNAT-2010, de las cuales la especie más abundante fue Anas platyrhynchos diazi y la menos representativa Falco peregrinus. La abundancia total estimada de las especies observadas para toda el área de estudio fue de 5945 individuos (intervalo de confianza al 95% = 5035; C.V. = 7.25%) y una densidad de 0.53 organismos/ha (intervalo de confianza al 95% = 0.49; C.V. = 7.25%). Este estudio demuestra que el manglar de Tumilco es fundamental para la conservación de la avifauna de Veracruz.

Published: June 2022

La mosca mexicana de la fruta, Anastrepha ludens (Loew) es una plaga de importancia económica en cultivos de cítricos y mango en México. Estudios del comportamiento sexual en cepas mutantes pueden contribuir en la selección de insectos con potencial para liberación en campo. En este estudio se evaluó la respuesta visual del mutante ojos amarillos de A. ludens mediante experimentos de elección de color para determinar posibles deficiencias visuales. Las pruebas de laboratorio se realizaron utilizando esferas de color verde, naranja y blanco, comparando la cepa mutante con moscas de cría del tipo silvestre utilizadas como testigo. Los resultados indicaron que las moscas mutantes no presentan discriminación en la elección del color, evidenciando posibles deficiencias visuales.

Published: June 2022

Se determinó la composición anual y estacional de la diversidad de anfibios y reptiles de Montecillo Santa Cruz, municipio de San Francisco del Mar, Oaxaca, en el Istmo de Tehuantepec. Entre noviembre de 2010 y noviembre de 2011, a lo largo de 48 días de muestreo (24 en la temporada seca y 24 durante la temporada húmeda), se establecieron transectos diurnos y nocturnos de 500 metros de longitud y ancho aproximado de 10 metros en pastizal abierto, nanchal, selva baja caducifolia y vegetación riparia. En un área de 20 km2 se registró un total de 49 especies (10 especies de anfibios y 39 especies de reptiles), lo que representa el 11.52% de la herpetofauna total para Oaxaca. De éstas, 46 especies se registraron en la temporada húmeda (10 anfibios y 36 reptiles) y 37 en la temporada seca (4 anfibios y 33 reptiles). El 30.61% del total se encuentra en alguna categoría de riesgo en la NOM-059-SEMARNAT-2010, una especie está catalogada como críticamente en peligro (Ctenosaura oaxacana) en la lista roja de la UICN, y cuatro más están en el apéndice II de la CITES. A lo largo del estudio, la selva baja caducifolia fue la asociación vegetal que presentó la mayor diversidad alfa (H´ = 3.2900, 1/D = 20.6), mientras que el pastizal presentó la menor diversidad (H´ = 3.1664, 1/D = 17.14). Para las dos temporadas monitoreadas, la selva baja caducifolia presentó la mayor diversidad (H´ = 3.2900, 1/D = 20.6; H´ = 3.0850, 1/D = 17.71, respectivamente), mientras que la menor diversidad se presentó en la vegetación riparia durante la temporada húmeda (H´ = 3.1009, 1/D = 16.61), y en el pastizal (H´ = 2.7095, 1/D = 11.40) durante la temporada seca. A lo largo de todo el estudio, las asociaciones vegetales que compartieron mayor número de especies fueron la selva baja caducifolia y la vegetación riparia (J = 0.7045 y S = 0.5613), coincidiendo con los resultados estacionales (J = 0.6500 y S = 0.4921 temporada húmeda; J = 0.6333 y S = 0.4489 temporada seca). Se registró una alta diversidad en un área relativamente pequeña, por lo que puede considerarse a la zona como de importancia para la distribución de anfibios y reptiles, de ahí que sea indispensable el establecimiento de medidas de manejo y conservación para estas especies y sus hábitats.
Psychological condition of the elderly in the nursing home
Authors: Silvia Efnida , Yarni Linda
Published: June 2022

Individuals who have good psychological conditions will commonly be able to create social relatedness and good moral feelings. The purpose of this study was to determine the social and moral feelings of the elderly in the Ikhwanus Shafa Lasi Mudo nursing home in Canduang District, Indonesia. This research used descriptive approach taking six key informants who are elderly residents aged 60 years and over, and the supporting informants consisted of two caregivers. The observation and interview results were analysed by reduction, presentation, verification, and comparison of the results. Specifically, this study focused on social feelings, sense of brotherhood, sympathy for friends who are in the orphanage environment, and sense of affection for others. It was found that in general, there showed a lack a sense of solidarity among others, a lack sense of help and respect. The elderly in this study informed that they developed such feelings that they are too close to the people in the orphanage compared to their family members. However, the moral feeling of the elderly has shown a good relationship between values and ethics (morals), where the elderly were able to take responsibility, feel guilty when violating norms, and feel at ease when obeying norms.

A two-part multi-algorithm concurrency control optimization strategy for distributed database systems
Authors:   Department of Computer Science, Northern Border University, Arar, Saudi Arabia, Shebka Nasser ,   Computer Science College, Al Neelian University, Khartoum, Sudan
Published: June 2022

In this paper, we propose a novel holistic approach to address the issues of concurrency control after an exhaustive examination of the problem and the various forms it can transpire. The proposed strategy was formulated depending on different perspectives that are based on exploring a wide range of algorithms, methods, and strategies proposed in practice and theory that attempted to address the problem and its forms, but only partially succeeded in doing so. Here we proposed a two-part holistic strategy to optimize concurrency control in distributed environments that address a wide range of concurrency control anomalies by taking advantage of several concurrency control algorithms' strengths while minimizing their weaknesses. The novelty of our approach transpires from two interconnected parts that can be applied regardless of the type of distributed database environment. The first is a structured tier-based data classification system based on data sensitivity with respect to serializability requirements and ranges from strict to very relaxed forms of serializability constraints. The second is a concurrency management algorithm that allocates the appropriate concurrency control algorithm to each transaction depending on the type of transaction and/or type of data being accessed from the aforementioned tier-based classification method. Our proposed method also incorporates a priority allocation mechanism within the concurrency management algorithm. Priority is allocated to different tier transactions depending on the tier's level, which in turn reflects data importance and sensitivity. Although our proposed strategy remains an algorithmic approach as we encountered various challenges regarding performance testing of a novel multi-algorithm approach for handling concurrency control in distributed database systems. However, future work involves testing the performance of our proposed strategy either through real-time systems after considerable adjustments or by constructing an appropriate customized simulation framework. Finally, the potentials of the strategy presented here are very promising, hence, we recommend as we are also optimistic that other scholars are encouraged to further exploit the concept of using multiple concurrency control algorithms within the same distributed database environment.
DSS fertirrigation system: An Italian case study
Authors: Cosoli Gabriele , Magaletti Nicola , Leogrande Angelo , Massaro Alessandro
Published: June 2022

The proposed paper deals with a Decision Support System (DSS) conceived for agronomists and farm managers involved in the fertirrigation (FER) process. The DSS has been developed within the Smart District 4.0 (SD 4.0) project, funded with the contribution of the Italian Ministry of Economic Development (MISE), aiming to sustain the digitization process of the Italian Small and Medium Enterprises (SMEs). The DSS is part of an integrated framework, mainly including advanced services for blockchain traceability and agriculture planning, optimizing the cooperation among different actors, such as farmers, agronomists and fertilizer suppliers. The most relevant and challenging part of the platform consists of Machine Learning (ML) supervised and unsupervised algorithms with high performance, to optimize production and quality in viticulture. Specifically, the Probabilistic Neural Network (PNN) model provides the performance about time shortage prediction when compared with other ML algorithm performance. Finally, the clustering k-Means algorithm is applied to extract information about active substances, doses, time of shortage, adversities, and pathogen elements, useful to optimize a FER plan. All the analyzed algorithms are applied to an experimental dataset. The work starts with the design of the processes and of the information flow able to optimize grape supply chain and traceability, and then focuses on data analysis. The data analysis approach is suitable to formulate precision farming rules.

Authors: Chekin Nasrin , Ayatollahi Haleh , Karimi Zarchi Mojgan
Published: June 2022

Background

Cervical cancer has been recognized as a preventable type of cancer. As the assessment of all the risk factors of a disease is challenging for physicians, information technology and risk assessment models have been used to estimate the degree of risk.

Objective

The aim of this study was to develop a clinical decision support system to assess the risk of cervical cancer.

Methods

This study was conducted in 2 phases in 2021. In the first phase of the study, 20 gynecologists completed a questionnaire to determine the essential parameters for assessing the risk of cervical cancer, and the data were analyzed using descriptive statistics. In the second phase of the study, the prototype of the clinical decision support system was developed and evaluated.

Results

The findings revealed that the most important parameters for assessing the risk of cervical cancer consisted of general and specific parameters. In total, the 8 parameters that had the greatest impact on the risk of cervical cancer were selected. After developing the clinical decision support system, it was evaluated and the mean values of sensitivity, specificity, and accuracy were 85.81%, 93.82%, and 91.39%, respectively.

Conclusions

The clinical decision support system developed in this study can facilitate the process of identifying people who are at risk of developing cervical cancer. In addition, it can help to increase the quality of health care and reduce the costs associated with the treatment of cervical cancer.

Authors: Mekhael Mario , Lim Chan Ho , El Hajjar Abdel Hadi , Noujaim Charbel , Pottle Christopher , Makan Noor , Dagher Lilas , Zhang Yichi , Chouman Nour , Li Dan L , Ayoub Tarek , Marrouche Nassir
Published: June 2022

Background

Patients with COVID-19 have increased sleep disturbances and decreased sleep quality during and after the infection. The current published literature focuses mainly on qualitative analyses based on surveys and subjective measurements rather than quantitative data.

Objective

In this paper, we assessed the long-term effects of COVID-19 through sleep patterns from continuous signals collected via wearable wristbands.

Methods

Patients with a history of COVID-19 were compared to a control arm of individuals who never had COVID-19. Baseline demographics were collected for each subject. Linear correlations among the mean duration of each sleep phase and the mean daily biometrics were performed. The average duration for each subject’s total sleep time and sleep phases per night was calculated and compared between the 2 groups.

Results

This study includes 122 patients with COVID-19 and 588 controls (N=710). Total sleep time was positively correlated with respiratory rate (RR) and oxygen saturation (SpO2). Increased awake sleep phase was correlated with increased heart rate, decreased RR, heart rate variability (HRV), and SpO2. Increased light sleep time was correlated with increased RR and SpO2 in the group with COVID-19. Deep sleep duration was correlated with decreased heart rate as well as increased RR and SpO2. When comparing different sleep phases, patients with long COVID-19 had decreased light sleep (244, SD 67 vs 258, SD 67; P=.003) and decreased deep sleep time (123, SD 66 vs 128, SD 58; P=.02).

Conclusions

Regardless of the demographic background and symptom levels, patients with a history of COVID-19 infection demonstrated altered sleep architecture when compared to matched controls. The sleep of patients with COVID-19 was characterized by decreased total sleep and deep sleep.

Published: June 2022

BACKGROUND

Some Canadians have limited access to longitudinal primary care, despite its known advantages for population health. Current initiatives to transform primary care aim to increase access to team-based primary care clinics. However, many regions lack a reliable method to enumerate clinics, limiting estimates of clinical capacity and ongoing access gaps. A region-based complete clinic list is needed to effectively describe clinic characteristics and to compare primary care outcomes at the clinic level.

OBJECTIVE

The objective of this study is to show how publicly available data sources, including the provincial physician license registry, can be used to generate a verifiable, region-wide list of primary care clinics in British Columbia, Canada, using a process named the Clinic List Algorithm (CLA).

METHODS

The CLA has 10 steps: (1) collect data sets, (2) develop clinic inclusion and exclusion criteria, (3) process data sets, (4) consolidate data sets, (5) transform from list of physicians to initial list of clinics, (6) add additional metadata, (7) create working lists, (8) verify working lists, (9) consolidate working lists, and (10) adjust processing steps based on learnings.

RESULTS

The College of Physicians and Surgeons of British Columbia Registry contained 13,726 physicians, at 2915 unique addresses, 6942 (50.58%) of whom were family physicians (FPs) licensed to practice in British Columbia. The CLA identified 1239 addresses where primary care was delivered by 4262 (61.39%) FPs. Of the included addresses, 84.50% (n=1047) were in urban locations, and there was a median of 2 (IQR 2-4, range 1-23) FPs at each unique address.

CONCLUSIONS

The CLA provides a region-wide description of primary care clinics that improves on simple counts of primary care providers or self-report lists. It identifies the number and location of primary care clinics and excludes primary care providers who are likely not providing community-based primary care. Such information may be useful for estimates of capacity of primary care, as well as for policy planning and research in regions engaged in primary care evaluation or transformation.

BACKGROUND

Using a personal cell phone in clinical settings by nurses is one of the emerging concerns in care delivery that can affect the quality of patients’ care.

OBJECTIVE

This study aimed to explore the experiences of nurses, patients, and patients’ relatives about using a personal cell phone by nurses.

METHODS

A qualitative inductive approach was used. This study used a purposive sampling method to interview 22 individuals, including nursing staff and patients and their relatives, at xxx Educational Hospital in XXX. Data were collected through semi-structured interviews and were continued to achieve the saturation point. The conventional content analysis method was used to analyze the data.

RESULTS

Our analysis revealed three main categories of 'Emotionless care,' 'Impaired professional behavior,' and 'Neglect in care.' The main theme extracted from this study was personal cell phone is a barrier to effective nursing care.

CONCLUSIONS

The health promotion of patients might be adversely influenced when nurses use a personal cell phone at the workplace. This study found that using a personal cell phone while working could jeopardize patients’ safety and tarnish the professional image. Nurses must formulate guidelines on how to use a personal cell phone while working in clinical settings.

Authors: Pekarsky Chloe , Skiffington Janice , Metcalfe Amy
Published: June 2022

BACKGROUND

The use of social media for study recruitment is increasingly common. Previous studies have typically focused on using Facebook; however, there is limited data to support the use of other social media platforms for participant recruitment, notably in the context of a pregnancy study.

OBJECTIVE

This study aimed to evaluate the effectiveness of Facebook, Twitter, and Instagram for recruiting a representative sample of pregnant women into a longitudinal pregnancy cohort study in Calgary, Alberta between September 27, 2021 and April 24, 2022.

METHODS

Paid advertisements were targeted to 18 to 50 year-old women in Calgary with interests in pregnancy. Data regarding reach, link clicks and cost were collected through Facebook Ads Manager and Twitter Analytics. The feasibility of each platform for recruitment was assessed based on recruitment rate and cost-effectiveness. Demographic characteristics of the participants recruited through each source were compared using chi-square tests.

RESULTS

Paid advertisements reached 159,778 social media users, resulting in 2390 link clicks and 324 recruited participants. Facebook reached and recruited the most participants, while Instagram saw the highest number of link clicks relative to the number of users who saw the advertisement (2.11%). Facebook and Instagram advertisements were cost-effective with an average cost-per-click of $0.61 and cost-per-completer of $7.89. Twitter advertisements were less successful in terms of recruitment and cost. Demographic characteristics of participants did not differ based on recruitment source except for educational attainment and income, where more highly educated and higher income participants were recruited through Instagram or Twitter.

CONCLUSIONS

Paid social media advertisements (especially Facebook and Instagram) were feasible and cost-effective methods for recruiting a large sample of pregnant women for survey research. However, future researchers should be aware of the potential for fraudulent responses when using social media for recruitment.
Materiality and Relevance in Financial Reporting. Interpretation Problems and Solutions Adopted Internationally.
Authors: Avi Maria Silvia
Published: June 2022

The concepts of relevance and materiality have, for decades now, been the subject of in-depth study by both doctrine and the bodies whose task it is to issue accounting standards. The aforementioned terms have different meanings in the various countries, although, in general, the difference in interpretation is only a nuance of concept that is often difficult even to identify. When moving from international standards to national standards issued by organisations within individual countries, translation issues can be identified that lead to the use of terms other than relevance and materiality but which, when reading the documents, essentially refer to those standards. As will be seen in the following pages, in Italy these concepts, although identified by different terms than relevance and materiality, have also been adopted by the criminal law concerning evasion and accounting. These concepts therefore transcend the issue of financial reporting to affect both auditing principles and the position of the judiciary, which, applying current legislation, appeals to the tenuity of the fact to reduce or cancel penalties connected with tax offences such as evasion of value added tax.

Background: Well-being at the workplace influences health and productivity and a negative work environment may lead to physical and mental health problems. Objectives: The current study aimed to measure the attitude and perception of the workforce towards work place environment and to identify key factors affecting workplace health and employee engagement and wellness. Methods: A survey study was conducted over a period of three months at Ras Al Khaimah Medical and Health Science University, United Arab Emirates. The Mental health America’s Workplace Mental Health Survey was used to collect data from a random sample of employees in the study settings. The objective of the study was adequately explained to participants and their informed consent was obtained with assured confidentiality. Results: The overall mean score of respondents satisfaction was 61.0 ± 8.1 SD. Employees responses towards workplace was significantly lower among full time university personnel than those at affiliated teaching hospitals (59.3±6.9 vs. 62,3±8.7, p=0.01). Work insecurity was the only item which was negatively correlated with the overall score (r= -0.72; p=0.02). The rate of absenteeism, Engaging in unhealthy behavior due to workplace stress and Speaking poorly about the workplace were strongly correlated with overall workplace health score (r=0.5;P=0.001). Support from colleagues and supervisor were correlated with overall job satisfaction (r=0.3 and r= 0.2; p=0.01 respectively). Conclusion: Respondents were generally happy with the state of their workplace. However, workplace perquisites such as open door policies, flexible time arrangement; opportunities for professional development promote more positive attitude and perceptions.

Since they offer an opportunity to create value for shareholders, a company's capital structure decision is crucial for its existence and performance and, therefore, has been addressed by several studies in the finance area. However, there is no unanimous answer determining the most efficient capital structure for a given organization and there is a lack of evidence regarding the use of optimal structure models in the daily lives of companies. The methodology in this work is composed of four phases to propose a practical method for decision-making on a company’s structure. First, it is defined the problem that will be simulated. Then, using the FCD and SMC techniques, the company's value is calculated and the insolvency risk is quantified. And finally, in the fourth phase, discussions are developed regarding the ideal capital structure for the company. The results simulated through the selection of an object study show the increase in the company's value from indebtedness, presenting opportunities to create value for its managers.The model has as a limitation the case study of only one segment, and can be expanded to other sectors in future works.Still, the proposal must be understood as beneficial for all stakeholders involved, since more competitive companies can provide products and/or services with superior quality and lower prices, being, therefore, a direct social contribution of the present proposal.

Published: June 2022

Abstract: Even in today's contemporary environment, anyone who mentions mental health is not taken seriously. When it comes to mental health, the person is portrayed as either aggressive or unstable. However, people with serious mental disorders are almost 10 times more likely than the general population to be victims of violent crime. Because many persons with psychological state difficulties are very engaged and valuable members of our communities, you most likely know someone with a psychological state problem and are not even tuned in to it[1]. This project intended to help people track their mental health without needing to consult a professional regularly. Javascript, CSS, HTML, Xampp, and PHP were used to develop the online portal.

Abstract: For an 3D IMAGE PROCESSING robot to truly succeed, there must be a variety of ways for robot to interpret its surrounding environment, both quickly and accurately. This report focuses on investigating improvements for a sub- problem of environmental perception, namely 3D image processing, referring to localizing and classifying objects of interests in a specified environment. The objects of interests in a process security scan of baggage or to analyse scans of materials to understand their structure. Recently python3 & machine learning programming approaches have made significant progress in the field of 3d object detection. Thus, several techniques have been developed for the real time tasks such as the autonomous robot. However, as images lack some information about depth which is essential for environmental perception for autonomous robot, they struggle a lot to preserve distance between object and robot. So, in this project in order to avoid such delays we have used high quality camera OF 1080p. This Report investigates the performance of both the minicomputers and as well as the cameras being mounted on the robot for 3d analysis which uses the state-of-the-3d image processing models. The end-to-end models of python3 and OpenCV are ultimately performed and experimented various times to perform 3D Detections. The models were trained and evaluated on the recently released data set and the most promising model was able to detect the 3d image of the object

Abstract: Fake news is incorrect information that is spread through a social network to harm individuals, authorities or organizations. The spread of fake news poses great challenges to society. Fake news is difficult to detect, but it is easy to spread and have widespread effects. Automated analysis of the reliability of articles is the subject of ongoing research. To address this issue, we offer a model that detects fake information and communications using deep learning and natural language processing. This paper presents a fake news detection model based on LSTM (Long Short-Term Memory) and Bi-LSTM (Bidirectional Long Short-Term Memory). In the first place, we want to present a dataset containing both fake news and genuine news, and perform various tests to sort out a fake news detector. The model was prepared and assessed utilizing a fake news dataset got from Kaggle.
Study of Sustainable Techniques for Effective Risk Management and Control: A Review

Published: June 2022

Abstract: A geological disturbance is a broader term that refers to a variety of ground motions such as rock falls, slope failure, and shallow debris flows. The study of landslides has fetched a lot of interest recently, owing to a growing awareness of the socioeconomic consequences associated. The land in the mountainous region is especially susceptible to landslides due to its complicated geological context. Landslides are generally caused by the slope changing from a stable to an unstable condition, which can be caused by a variety of factors such as pore water pressure destabilising the slopes, loss or absence of vertical vegetative structure (after a wild fire or fire in forests lasting two or four days), erosion of toe of slopes by river, significant rain falls, earthquakes causing liquefaction of slope, blasting, earth work which alters the slope and imposes new load on it. If the slope is not stable and must support a large soil mass, the entire wedge may slide, resulting in the second type of landslide. Although climate change has also contributed to the occurrence of such disasters like landslides. As we all are aware about the relative causes of landslides, still it is a major concern for governmental organisations, authorities, geotechnical engineers and sub-urban planners for both public and structural safety. Landslides are a major issue in hilly areas especially in Himalayan region of India, where populace is more dependent on native resources and are prone to landslides too.

Published: June 2022

Abstract: Energy has become the most vital part of the lives of all the people in the entire world. Power consumption is very high in highly populated countries like India and China. Thus, the increasing energy demand has made companies around the world invest more in the research and development of eco-friendly harvesting of energy. Solar, wind, and nuclear energy have been successful to some extent. Humans can produce electricity through their day-to-day activities but all this energy is getting wasted. In this modern life, hitting the gym has been increasing. Since the majority of the people spend their time in the gym this human energy can be used to generate power i.e., by modifying the gym equipment. This project harnessed the mechanical energy of the machine and converted it to electrical energy by the means of a generator-based system. This is the time to think of alternative sources of energy. This project uses the rack and pinion method along with the alternator to generate electricity.
