Detecting Item Preknowledge Using Revisits With Speed and Accuracy
Authors: Demirkaya Onur , Bezirhan Ummugul , Zhang Jinming
Published: February 2023

Examinees with item preknowledge tend to obtain inflated test scores that undermine test score validity. With the availability of process data collected in computer-based assessments, the research on detecting item preknowledge has progressed on using both item scores and response times. Item revisit patterns of examinees can also be utilized as an additional source of information. This study proposes a new statistic for detecting item preknowledge when compromised items are known by utilizing the hierarchical speed–accuracy revisits model. By simultaneously evaluating abnormal changes in the latent abilities, speeds, and revisit propensities of examinees, the procedure was found to provide greater statistical power and stronger substantive evidence that an examinee had indeed benefited from item preknowledge.

Published: February 2023

Introduction. The paper presents the results of a hygienic assessment of the intensity levels of electric and magnetic fields of industrial frequency and the functional state of the human body when using shielding personal protective equipment against electric fields of industrial frequency on open switchgears with a voltage of 220-750 kV in the warm season. The study aims to explore the functional state of the human body using personal protective equipment against industrial frequency electric fields during work on open switchgears with a voltage of 220-750 kV, and the possibility of their regulation depending on the thermal load of the environment. Materials and methods. The specialists measured the levels of electric and magnetic fields of industrial frequency in accordance with MUK 4.3.2491-09. Eight volunteers took part in the study to assess the functional state of the human body when using personal protective equipment against industrial frequency electric fields. Volunteers performed the work of electrical personnel for 60 minutes followed by a 30-minute recovery. We monitored environmental parameters based on measurements of the environmental heat load index and recorded indicators such as skin temperature and humidity, temperature and humidity under clothing, moisture loss. Results. At the considered electric grid facilities, the researchers recorded the excess of remote adjustment of the electric field of industrial frequency up to 30 kV/m, in this regard, the use of personal protective equipment is mandatory. The obtained results of studies of the functional state of the human body revealed a tendency to increase the voltage of the mechanisms of thermoregulation of the human body using personal protective equipment against electric fields of industrial frequency when working on open switchgear. Limitations. The number of volunteers was due to limited access to production facilities. Conclusion. The regulation of work and rest modes of personnel when working in an open area during the warm season according to the index of the thermal load of the environment requires adjustment, since the studies have shown the need for stricter time regulation when operating personal protective equipment against an electric field of industrial frequency in a heating environment, taking into account their influence on the thermal and functional state of the human body. Ethics. The study was approved by the Local Ethics Committee of the Izmerov Research Institute of Occupational Health (extract from the minutes of the meeting No. 3 dated 03/23/2022).

The methodology can be used to conduct research on the influence of personal protective equipment for various purposes, design, configuration, composition of the package of materials on the thermal condition of those working in a heating environment, including in comparative terms.
A Case for Information Retrieval Systems
Authors: Brandenburg Jan Gerit
Published: February 2023

Many steganographers would agree that, had it not been for consistent hashing, the study of link-level acknowledgements might never have occurred. Given the current status of decentralized algorithms, information theorists clearly desire the study of link-level acknowledgements, which embodies the theoretical principles of cryptoanalysis. In our research we disconfirm not only that the much-touted large-scale algorithm for the refinement of red-black trees by Wang and Maruyama runs in $\Theta$($ ( \sqrt{\log \log ( n + \sqrt{n} )} + n ) $) time, but that the same is true for DHTs.

Published: February 2023

Background: Adherence to adjuvant endocrine therapy (AET) is low in women with breast cancer. Negative beliefs about the necessity of AET and high concerns are barriers to adherence.Purpose: To use the multiphase optimization strategy to optimize the content of an information leaflet intervention, to support AET beliefs. Methods: We conducted an online screening experiment using a 2^5 factorial design to optimize the leaflet. The leaflet had five components, each with two levels; 1) diagrams about AET mechanisms (on/off); 2) infographics displaying AET benefits (enhanced/basic); 3) AET side-effects (enhanced/basic); 4) answers to AET concerns (on/off); 5) breast cancer survivor (patient) input: quotes and photographs (on/off). Healthy adult women (n=1604), recruited via a market research company, were randomized to one of 32 experimental conditions, which determined the levels of components received. Participants completed the beliefs about medicines questionnaire before and after viewing the leaflet. Results: There was a significant main effect of patient input on beliefs about medication (β=0.063, p<0.001). There was one significant synergistic two-way interaction between diagrams and benefits (β=0.047, p=0.006), and one antagonistic two-way interaction between diagrams and side-effects (β=-0.029, p=0.093). There was a synergistic three-way interaction between diagrams, concerns and patient input (β=0.029, p=0.085), and an antagonistic four-way interaction between diagrams, benefits, side-effects and concerns (β=-0.038, p=0.024). In a stepped approach, we screened in four components and screened out the side-effects component. Conclusion: The optimized leaflet did not contain enhanced AET side-effect information. Factorial experiments are efficient and effective for refining the content of information leaflet interventions.
PROPAGANDA ANALYSIS OF INDEPENDENT PAPUA ORGANIZATIONS: PREVENTIVE EFFORTS FOR NATION DISINTEGRATION
Authors: Suryawijaya Tito Wira Eka
Published: February 2023

The Armed Criminal Group (KKB) in Papua is still conducting acts of terror such as burning public facilities, killing people, and spreading propaganda through social media, which could threaten the integrity of Papua as part of Indonesia. This study used a critical discourse analysis approach to identify various propaganda for Free Papua, collected from uploads on Facebook owned by KKB Papua and its sympathizers. The propaganda claims that TNI and Polri conduct open operations, form militias, and commit violence and torture against the Papuan people. Non-Papuan Indonesians are labeled with derogatory words, while Papuan students are persecuted. Independence is seen as a way to liberate Papua from Indonesian colonialism, with demands for a referendum and termination of special autonomy. KKB also proclaimed a provisional Constitution (UUD) and rejected Indonesian legal products. The propaganda techniques used by KKB include card stacking, name calling, glittering generalities, and bandwagons. To overcome this propaganda, efforts are needed to provide correct and reliable information, education, and instill a sense of belonging to Indonesia for the Papuan people. By doing so, acts of propaganda and separatism by the Free Papua Movement can be overcome, and the integrity of the nation can be maintained.

Authors: Mournet Annabelle , Bal Vanessa , Selby Edward A. , Kleiman Evan
Published: February 2023

This study aims to develop a measure to assess different facets of social connection that is valid among both autistic and non-autistic adults. The sample consisted of 200 participants recruited online. Participants completed an initial set of 35 items. Exploratory factor analyses and confirmatory factor analyses were performed. Four-factor models were produced by the EFAs. Item reduction resulted in the development of two 8 item versions of the Connections With Others Scale (CWOS), one of which is intended for autistic populations (CWOS-AV). Both scales include factors for value, similarity, and time spent. Factor four was difference in the CWOS and member in the CWOS-AV. Autistic participants had significantly greater motivation/desire to connect with others compared to non-autistic participants (t(195)=3.39; p <.001). These measures will allow for greater ability to assess the motivation to connect with others, resulting in improved ability to produce research that clarifies theories and describes psychological phenomenon.
Submission to Senate Inquiry into the Housing Australia Future Fund Bill 2023 and other bills
Authors: Murray Cameron
Published: February 2023

The proposed Housing Australia Future Fund (HAFF) is a bad policy. Its main outcome is to unnecessarily pay millions each year in fees for financial management.If the objective is to make homes cheaper for Australians, it is not clear why the HAFF is better than doing nothing. The basic problem is that the HAFF does not produce new below-market housing of any sort. It instead uses money to buy non-housing assets.Just like forcing households to buy non-housing assets with their income makes it harder for them to buy a home to live in, so too does the HAFF make it harder for governments to invest in housing. The $10 billion could be spent on building or acquiring new public housing directly, or via state public housing agencies rather than on non-housing assets. If financial trickery is desired, these funds can be swapped for equity shares for accounting purposes.What seems to be overlooked it that housing, including public housing, is a financial asset that makes a high return over time. In fact, the total return on the typical Australian home has exceed the total return on the Future Fund, which would manage HAFF investments, since its inception in 2006. The bulk of this housing return comes from capital gains, which are returns that also accrue to public housing agencies who rent far below market prices. This is why public housing is well known to be the most cost-efficient way to provide below-market priced housing to residents, and why instead of a HAFF these funds should be used to directly build more public housing dwellings.

Published: February 2023

Bahasa pemrograman adalah kumpulan aturan yang diatur sedemikian rupa untuk memungkinkan pengguna komputer membuat program yang dapat dijalankan dengan aturan tersebut. Bahasa pemrograman dapat dikelompokkan dalam berbagai cara. Salah satu pengelompokan bahasa pemrograman adalah pendekatan notasi bahasa pemrograman, apakah lebih dekat dengan bahasa mesin atau bahasa manusia. Dengan demikian, bahasa pemrograman dapat dikelompokkan menjadi dua, yaitu bahasa tingkat rendah dan bahasa tingkat tinggi. Bahasa tingkat tinggi adalah bahasa yang mudah dipahami oleh manusia, c++ adalah contoh bahasa tingkat tinggi. Contoh bahasa tingkat tinggi lainnya adalah Pascal, Perl, Java, dan sebagainya. Sedangkan bahasa tingkat rendah adalah bahasa mesin atau bahasa rakitan. Secara sederhana, komputer hanya dapat menjalankan program yang ditulis dalam bahasa mesin. Oleh karena itu, jika suatu program ditulis dalam bahasa tingkat tinggi, program tersebut harus diproses terlebih dahulu sebelum dapat dijalankan di komputer. Ini adalah salah satu kelemahan bahasa tingkat tinggi di mana dibutuhkan waktu untuk memproses sebuah program sebelum dieksekusi. Namun, bahasa tingkat tinggi memiliki banyak keuntungan. Bahasa tingkat tinggi mudah dipelajari, mudah ditulis, mudah dibaca dan tentunya mudah ditemukan kesalahannya. Pada makalah ini akan dibahas salah satu bahasa tingkat tinggi yaitu C++. Bahasa ini diciptakan oleh Bjarne Stroustrup pada tahun 1980-an. Sebagai bahasa berorientasi objek, C++ memudahkan pembuatan aplikasi berskala besar. Sebagai bahasa tingkat tinggi, yang menggunakan perintah-perintah yang mudah dipahami orang, C++ memiliki kelebihan karena sifatnya yang universal. Sebagai bahasa universal, C++ dapat ditemukan di berbagai platform (Linux, Unix, Windows, Mac, dan lainnya). Artinya, jika kita menguasai C++ di platform PC, sangat mudah untuk beralih ke Linux atau sistem operasi lain.
The global recurrence and variability of kinship terminology structure
Authors: Passmore Sam
Published: February 2023

The extent to which kinship terminology varies between linguistic groups is a long-debated but unresolved social and linguistic puzzle. Contemporary research shows that a six-category typology is overly simplistic, but no alternatives have reached broad acceptance. This paper takes a data-driven solution to this problem. Using data from the release of Kinbank, a global database of 1,156 kinship terminology, I quantitatively review the global diversity of kinship terminology to derive a more granular typology of kinship terminology. In a two-part analysis, I show that kinship terminology structure is more diverse than is often assumed across three metrics. Firstly, more than six types are needed to represent the global diversity of kinship terminology. Secondly, typological categories are not equally variable. Some categories may contain identically structured terminology. Others may contain languages that only share a single feature. Finally, different subsets of kin (e.g. cousins vs grandparents) show different levels of variability. In the second part of the analysis, I explore the global distribution of the new typological categories, identifying globally and locally recurring structures. My analysis demonstrates how data can carve this semantic domain at its joints to identify observed clusters of diversity.
Daily arousal variation has little effect on sustained attention performance
Authors: Johnson Katherine , Bond Isobel , Machida Keitaro
Published: February 2023

Sustaining attention is an important cognitive process for everyday functioning and arousal is thought to underpin its performance. Primate studies depict an inverted-u relation between sustained attention and arousal, in which sustained attention performance is most affected at the extreme levels of arousal and peak performance aligns with moderate arousal. Human research findings are, however, inconsistent. This study aimed to investigate the effects of arousal on sustained attention performance in humans using two approaches - a small-N study with an inbuilt replication to test within-participant variation, and a larger sample assessing between-participant variation. The Sustained Attention to Response Task (SART) was used to measure sustained attention performance and the Karolinska Sleepiness Scale (KSS) was used to measure arousal. In the small-N study five participants completed the SART and KSS once an hour between 7 a.m. and 7 p.m., repeated two weeks later. Significant, curvilinear variation in KSS across time-of-day was found. A linear association between SART response time variability (sigma) and KSS was noted, however no other consistent associations between the SART and KSS were found. In the large-N study, 161 participants completed the SART and KSS once, at a time of day of their choosing. There were no significant relations between SART measures and the KSS, indicating that subjective sleepiness was not related to sustained attention performance. Overall, the hypothesized inverted-u relation between arousal and sustained attention performance was not found. The results suggested that diurnal arousal variation does not modify sustained attention performance in adults.

What is a behavioral spillover? How can a spillover be uncovered from the data? What is the precise link between the underlying psychological theory of a spillover and the econometric assumptions which are necessary to estimate it? This paper draws on recent advancements in causal inference, behavioral economics, psychology, and neuroscience to develop a framework for the causal evaluation and interpretation of behavioral spillovers. A novel research design is suggested. The paper challenges existing empirical strategies and reevaluates of existing empirical results.
Memorability Effects Emerge in Incidental Visual Working Memory
Authors: Green Taryn , Tam Joyce , O'Donnell Ryan Edward , Wyble Brad
Published: February 2023

Memorability denotes a stimulus-intrinsic property that results in stimuli being more likely to be remembered or forgotten. The effect is consistent across observers and can be measured in various stimuli such as faces and scene images. Long-term memory (LTM) paradigms have been used to measure memorability with studies demonstrating long-term memorability effects via incidental and intentional encoding mechanisms. The current study expands the understanding of memorability and examines whether memorability modulates the ability to unexpectedly report an image at short intervals. Three sets of experiments (using faces and scenes) with replications used an Attribute Amnesia (AA) paradigm to measure the effect of memorability on incidental visual working memory (VWM) processes while controlling attentional priorities. When participants had to identify the target image in the immediate trial unexpectedly, we observed that memorable targets yielded a higher accuracy compared to forgettable targets, suggesting that people incidentally remember more information about memorable stimuli even across very short intervals. This memorability benefit was observed for both stimulus types but was greater for faces compared to scenes. Thus, memorability modulates the ability to remember stimuli in an incidental VWM task. These results expand our understanding of the mechanisms behind memorability effects, and how attentional filters impact memory traces.
Predicting Juvenile Delinquency and Criminal Behavior in Adulthood Using Machine Learning
Authors: Schroeders Ulrich , Mariss Antonia , Sauter Julia , Jankowsky Kristin
Published: February 2023

By violating social norms, deviant behavior is an important issue that affects society as a whole and has serious consequences for its individuals. Different scientific disciplines have proposed theories of deviant behavior that often fall short of predicting actual behavior. In this registered report, we used data from the longitudinal National Study of Adolescent to Adult Health (Add Health) to examine the predictability of juvenile delinquency (Wave I) and adult criminal behavior (Wave V), distinguishing between drug, property, and violent offenses. Comparing the predictive accuracy of traditional regression models with different machine learning algorithms (elastic net regression and gradient boosting machines), we found the elastic net regressions with item-level data performed best. The prediction of juvenile delinquency was relatively accurate for drug offenses (R² = .57), violent offenses (R² = .44), and property offenses (R² = .39), while the performance declined significantly for adult delinquency, with R² values ranging from .16 to .13. Key predictors of juvenile delinquency versus adult criminal behavior were clearly different from each other. Early risk factors for adult criminal behavior included prior juvenile delinquency, particularly drug-related offenses, sex, and school-related issues such as suspension or expulsion. We discuss the findings in the context of relevant theories on the causes and development of criminal behavior and explore potential approaches for prevention and early intervention, particularly within the framework of the “Central Eight”.
It Is Not Real Until It Feels Real. Testing New Method for Simulation of Eyewitness Experience with Virtual Reality Technology and Equipment
Authors: Glomb Kaja
Published: February 2023

Laboratory research in the psychology of witness testimony is often criticized for its lack of ecological validity, including the use of unrealistic artificial stimuli to test memory performance. The purpose of our study is to present a method that can provide an intermediary between laboratory research and field studies or naturalistic experiments that are difficult to control and administer. It uses Video-360° technology and virtual reality equipment, which cuts subjects off from external stimuli and gives them control over the visual field. This can potentially increase the realism of the eyewitness's experience. To test the method, we conducted an experiment comparing the immersion effect, emotional response, and memory performance between subjects who watched a video presenting a mock crime on a head-mounted display (VR goggles; n = 57) and a screen (n = 50). The results suggest that, compared to those who watched the video on a screen, the VR group had a deeper sense of immersion, that is, of being part of the scene presented. At the same time, they were not distracted or cognitively overloaded by the more complex virtual environment, and remembered just as much detail about the crime as those viewing it on the screen. Additionally, we noted significant differences between subjects in ratings of emotions felt during the video. This may suggest that the two formats evoke different types of discrete emotions. Overall, the results confirm the usefulness of the proposed method in witness research.
Translating Intersectionality to Fair Machine Learning in Health Sciences
Authors: Lett Elle , La Cava William
Published: February 2023

Machine learning (ML)-derived tools are rapidly being deployed as an additional input in the clinical decision-making process to optimize health interventions. However, ML models also risk propagating societal discrimination and exacerbating existing health inequities. The field of ML fairness has focused on developing approaches to mitigate bias in ML models. To date, the focus has been on the model fitting process, simplifying the processes of structural discrimination to definitions of model bias based on performance metrics. Here, we reframe the ML task through the lens of intersectionality, a Black feminist theoretical framework that contextualizes individuals in interacting systems of power and oppression, linking inquiry into measuring fairness to the pursuit of health justice. In doing so, we present intersectional ML fairness as a paradigm shift that moves from an emphasis on model metrics to an approach for ML that is centered around achieving more equitable health outcomes.
Gender inequalities in participation in social clubs in Europe: the role of country-level women’s empowerment
Authors: Solé-Auró Aïda , Arpino Bruno
Published: February 2023

This study examines gender inequalities in intensive engagement in participation in social clubs among older people and how this relates to country-level women’s empowerment. Combined individual-level data from the Survey of Health, Ageing and Retirement in Europe (SHARE) and country-level data on Women’s Political Empowerment Index (WPEI) are used to conduct the analysis among 41,185 non-working individuals aged 65–84 across 19 countries. Multilevel regression analyses are conducted to address our aims. We detect notable between-country variations in the levels of participation. Substantial differences in the WPEI reflect marked contextual cross-country differences in gender equality. In about half of the countries gender differences in participation in social clubs are not encountered. However, we see that women are more likely to participate in social clubs in more gender egalitarian countries such as France, Denmark, Luxembourg and the Netherlands; while in 3 countries more men than women are engaged in social clubs (Italy, Czech Republic and Croatia). Cross-country gender differences in participation in social clubs point to the importance of cultural factors in influencing opportunities for active ageing.

Understanding the changes in land use and land cover (LULC) is essential in managing and monitoring the resources and planning. This study has analyzed the LULC changes in the years between 1992 and 2017 in Manamati watershed, Kathmandu district. Google Earth Engine Java Script API has been used to prepare LULC database. The supervised classification of a maximum likelihood algorithm is also used to prepare LULC database. The result shows that more than 6% land of the cultivated area has been converted into built-up area from 1992 to 2017, and 2.43 km2 area has increased in built-up area. The forest-covered area seems to be constant, and it is not a significant change over the last 25 years. However, proper watershed management practice and land use planning require to control the threats to watershed resources. The results of this study could be a reference to the future planning of watershed resource management.

El enfrentamiento a las adicciones desde la promoción de salud, precisa de la actuación conjunta de profesionales que incidan en los jóvenes de la comunidad universitaria. El objetivo de esta investigación consistió en diagnosticar el modo de actuar de los jóvenes universitarios frente a las adicciones, de forma tal que por medio de acciones de promoción de salud se contribuya a prevenir dichas adicciones, y así fomentar una cultura saludable en la comunidad universitaria villaclareña cubana. Teniendo en cuenta la flexibilidad metodológica, se empleó como métodos los correspondientes a la vía inductiva, técnicas cualicuantitativas, desde el nivel teórico al empírico. La investigación se desarrolló en la Facultad de Tecnología de la Salud y Enfermería de la Universidad de Ciencias Médicas de Villa Clara, Cuba, durante los meses de febrero 2020 a marzo 2021. Los resultados obtenidos del diagnóstico corroboraron el predominio del consumo de tabaco y alcohol sobre la combinación de medicamentos con bebidas alcohólicas, donde los primeros contactos con drogas se produjeron durante la segunda década de vida, a partir de los 16 años de edad, con un comportamiento similar en relación con la edad de inicio en ambos sexos. Se concluye que, aunque el consumo de drogas no constituye un agudo problema de salud en la comunidad universitaria villaclareña, si es preciso incrementar las acciones de promoción de salud para prevenir dichas adicciones y fomentar una cultura saludable con mayor calidad de vida.

El objetivo del estudio fue describir, la bioética social durante la pandemia COVID-19 y su uso o retiro de las mascarillas después de la vacunación. El estudio se realizó en agosto de 2021 donde se seleccionó mediante un muestreo no probabilístico intencional, 97 personas (45 hombres y 52 mujeres) que residen en las ciudades de Ica, Puno y Tacna (Perú) y para lo cual, mostraron una segunda administración de dosis vacunal contra la COVID-19. Se estableció, cuatro intervalos de clases de edades: I) 45-50, II) 51-55, III) 56-60, y IV) 61-65, diferenciados por sexo donde se les preguntó lo siguiente: “¿Si usted, está vacunado (a), cree que debería usar la mascarilla? Si __ No __” “¿Usa usted, doble mascarilla en las vías públicas o en espacios públicos? Si __ No __” “¿Con frecuencia consume alimentos en lugares públicos con su familia? Si __ No __”. Asimismo, la relación entre usar y retirar la mascarilla por sexo correspondió a: hombres (si = 24; no = 21), mujeres (si = 35; no = 17) donde en ambos sexos se indicó, que usar la mascarilla es la preferencia. La proporción para ambos sexos fue: hombres = 1,1 y mujeres = 2,1. Se concluye, que la acción de vacunarse, no argumenta retirarse la mascarilla y así se observó desde la preferencia mayor para su uso como medio de protección en hombres y mujeres desde los 45 hasta 65 años lo cual mostró, una bioética social para el cuidado de la salud humana.

El estadio larvario es una fase compleja en la acuicultura y se necesita de organismos vivos para la supervivencia y el desarrollo de los peces. El objetivo del estudio fue describir la longitud del suche (Trichomycterus rivalatus Valenciennes, 1846) con alimentación viva en el Lago Titicaca, Perú. El estudio se realizó en el laboratorio de cultivo prototipo de la Fundación Titicaca Perú (FUNTI-PERU), Centro Poblado de Ichu, Puno. Se utilizó como material biológico, 900 pre-larvas de T. rivulatus donde se distribuyó en tres tratamientos experimentales con tres réplicas de 100 individuos cada uno. Las pre-larvas se obtuvieron después que transcurrieron las 24 horas post-eclosión que pertenecieron al mismo desove. Se midió la temperatura, el oxígeno disuelto y pH como parámetros físico-químicos de calidad del agua. Se evaluó la sobrevivencia ante el consumo del saco vitelino, nauplios de Artemia salina y cladóceros. Se midió la longitud total al 5to día de eclosión. La temperatura del agua fue 14°C, el oxígeno disuelto se encontró entre 6,18-6,23 y el pH alrededor de 7,6. La sobrevivencia fue casi del 100% y la mayor longitud se observó con alimentación de A. salina (8,5 > 8,0 mm), donde existió diferencias estadísticamente significativas. Se concluye, que la longitud de 8,5 mm en T. rivalatus durante el periodo pre-larvario requiere que las condiciones experimentales físico-químicas con temperatura de 14°C, oxígeno disuelto en el rango 6,18-6,23 y pH alrededor de 7,6 lo cual, garantizará una sobrevivencia casi total, si la estrategia eficiente de alimentación es con nauplios de artemia.

Los humedales proveen múltiples servicios ecosistémicos que garantizan el desarrollo social, económico y ambiental de la población; sin embargo, estos sufren diversos impactos ambientales que aceleran el proceso de la eutrofización. El presente trabajo evalúa los estados tróficos de la laguna principal del Área de Conservación Regional Albufera de Medio Mundo (ACRAMM), Huaura, Lima, Perú. Para ello, se utilizó el Índice de Estado Trófico de Carlson modificado por Toledo (IETM) y se formuló un modelo matemático predictivo para el fósforo total del agua; donde la variable dependiente fue representada por el parámetro, y las independientes, por las reflectancias de imágenes Sentinel-2. El ACRAMM, según el modelo para el fósforo, resultó eutrófico en las cinco primeras fechas evaluadas (IETMPT > 65,56) y oligotrófico a eutrófico con tendencia de incremento de sur a norte en la última evaluación (IETMPT = 38,29-56,99). Estos resultados permiten concluir que el estado trófico del ACRAMM se encuentra en la clasificación más alta del índice, principalmente por las siguientes fuentes contaminantes: desagüe agrícola, vertimiento de aguas residuales industriales, poza de oxidación del Centro Poblado de Medio Mundo, actividades de pastoreo, instalaciones turísticas y las estaciones de bombeo de agua instaladas en áreas adyacentes.

La rabia canina es un problema de salud vigente, muy importante para la salud pública, la producción ganadera y la economía. El objetivo de esta investigación fue evaluar la distribución espacio-temporal de la rabia canina en el periodo 2009-2018 en La Habana, Cuba. Se realizó un estudio observacional descriptivo, retrospectivo de forma pasiva y de corte transversal. Para el análisis estadístico se empleó el software Epidat, versión 3.1, basado en matriz de Microsoft Excel. Se determinaron los indicadores epidemiológicos: prevalencia de casos, serie temporal mensual y tendencia acumulada de focos. Mientras que, para el análisis espacial, se calcularon las coordenadas geográficas a partir del centroide de cada municipio. Para la visualización se utilizó el programa QGIS versión 3.0.1 y las bases cartográficas de GEOCUBA. Se realizó la comparación de proporciones para los casos positivos entre las áreas periféricas y centrales, las que se graficaron en el paquete estadístico BlueSky Statistics versión 6.0.7. Como resultado se obtuvo que la mayor densidad poblacional de caninos/km2 se encuentra en el conjunto de los municipios 10 de Octubre - Centro Habana-Habana Vieja; seguido en orden decreciente del conjunto del Oeste (La Lisa-Playa-Marianao-Regla) y la menor densidad poblacional en el grupo Cotorro-Guanabacoa-Habana del Este. Se reveló proporciones altamente significativas de focos en las áreas geográficas periféricas, respecto a las centrales. Se mostró en la serie temporal mensual de focos rábicos, un comportamiento paralelo en el tiempo desde el año 2009 hasta el 2013, con incremento entre febrero de 2014 hasta octubre de 2015, y un pico en el mes de agosto, además hubo una disminución en el mes de noviembre del 2018. Se concluye que existe una tendencia a variaciones significativas en la distribución espacial y temporal de la rabia canina en La Habana en el periodo 2009-2018.

El objetivo del estudio fue describir la función intelectual de la capacidad de memoria de trabajo (CMT) en estudiantes universitarios desde un caso de estudio. Se realizó, el estudio de junio a julio de 2022 y de forma probabilística aleatoria se seleccionaron, seis estudiantes de semilleros de investigación que pertenecen a la Universidad Nacional “San Luis Gonzaga” (Ica, Perú). El análisis de la CMT fue mediante dos tipos de juegos didácticos (JD) con diferentes grados de complejidad: 1ro) adivinanza de cubos de colores y 2do) marcaje y reconocimiento de tres conchas de mar entre un número total de 100 conchas. Cada JD se replicó dos veces siendo preparatorio el primero para la estimulación de la concentración mental ante el análisis de la CMT. Los JD se replicaron dos veces y en caso del segundo se midió el tiempo (s) inmediato de reconocimiento donde la comparación de las medianas fue, a través de la prueba U de Mann-Whitney. Se observó, que el tiempo de cada réplica y el error de coincidencia en el JD del marcaje y reconocimiento de las tres conchas fue: U = 11,0 y p = 0,25. Aunque, disminuyó el error de coincidencia en la réplica 2 y denotó mayor CMT. Se concluye, que la función intelectual de la CMT se posibilita desde los JD, pues representan un estímulo emocional. Sin embargo, se necesitan prácticas que mejoren el aprendizaje y particularmente, desde la observación para la comprensión sobre objetos a seleccionarse.

La identidad de un territorio se cimenta día a día y se ve reflejada a través de su historia mediante la expresión de cultura y lenguaje. Por tanto, la preservación lingüístico-cultural representa un pilar para la propia identidad de la nación. Sin embargo, coexisten hechos contrarios a las buenas políticas culturales que protegen lo autóctono y la identidad nacional: la invasión y divulgación de culturas foráneas globalizadas, así como la penetración de un léxico contaminante para la lengua materna. Se suman otros fenómenos lingüísticos ―agramaticales―, sustentados por cierto “lenguaje estereotipado de moda”. Penosamente, gran responsabilidad de ello recae en los medios de comunicación masiva, donde se desempeñan profesionales que utilizan ese tipo de lenguaje, el cual se impregna y se hace eco en la sociedad; inclusive, en el ámbito científico, académico. Esto puede constatarse en la oralidad y en documentos escritos por profesores de la Universidad de Ciencias Médicas de Villa Clara, Cuba. Consecuentemente, para afrontar y revertir esta situación, se realizó el presente estudio cuyo objetivo fue defender las normas y principios del idioma para la preservación de la identidad lingüística en la academia. Metodológicamente, constituye un estudio cualitativo, descriptivo y sincrónico, el cual se enmarca entre 2019 y primer semestre de 2022. La muestra textual estuvo integrada por 12 ponencias pertenecientes a profesores de distintas especialidades impartidas en la universidad mencionada. También se registraron datos significativos tomados de la oralidad. Se emplearon los métodos teóricos análisis-síntesis e inducción-deducción, por ser significativos en el proceso, además, los métodos empíricos de observación y revisión documental para descubrir y acumular los datos necesarios. Un aspecto indispensable fue la observación y registro sistemático del lenguaje utilizado por periodistas y profesionales que desempeñan su labor en distintos medios de difusión masiva. En los resultados se recogieron 216 hechos que constituyen insuficiencias en el lenguaje de los universitarios participantes en la investigación ―138 de ellos recaen en el plano oral (63%), mientras 78, en la escritura (36%)―. Ello se debe a que el lenguaje oral es espontáneo, rápido y situacional, mientras que la escritura está más expuesta a la revisión y corrección. Una conclusión insoslayable: en los fenómenos mostrados se constata lo permeado de carencias en que se encuentra el lenguaje de dichos docentes, así como la influencia ejercida por los medios de difusión masiva en los hechos descritos.

Background: P-element induced wimpy testis (PIWI)-interacting RNAs (piRNAs) are the most mysterious class of small non-coding RNAs. They limit gene expression in gonads and sequence diversity. Dysregulated piRNAs can led to all kinds of cancers. Recently, piRNAs were postulated to be potentially useful biomarkers for tumor diagnosis and prognosis. However, there lack a systematic review of prognostic and diagnostic piRNAs in neoplasms. The study aimed to decipher the relationships between piRNAs expression, diagnostic and prognostic outcome in tumors.
Methods: This study systematically searched Google Scholar, MEDLINE, Scopus, PubMed, Embase, ScienceDirect, Ovid-Medline, Chinese National Knowledge Infrastructure, WanFang and SinoMed databases for relevant articles published before July 13, 2022. The study is registered in PROSPERO (CRD42020208717).
Results: Thirty relevant studies were included in the meta-analysis: 19 on diagnosis and 23 on prognosis. The pooled adds ratio, 95% confidence intervals (Cl) and hazard ratios (HR) of the studies were used to investigate the clinical parameters and overall survival (OS) of cancer patients. The area under the curve (AUC), sensitivity, and specificity was 0.82, 79%, and 77% in tumors, respectively. Though abnormally expressed piRNAs were associated with poor and unfavorable impacts on the OS time of cancer patients (HR=1.00, 95% Cl: 1.00-1.00, P<0.00001). Meanwhile, piRNAs in the breast cancer had favorable impacts on the OS (HR=0.70, 95% CI:0.45-1.09). However, the piRNAs in cell renal cell carcinoma, colorectal cancer, diffuse large B-cell lymphoma and gastric cancer had bad favorable impacts on the OS (HR=1.46, 95% CI:1.37-1.55; HR=1.56, 95% CI:1.24 -1.95; HR=2.19, 95% CI:1.25-3.86; HR=1.01, 95% CI:0.97-1.04, respectively).
Conclusions: The results strongly suggested that piRNAs were potential novel prognostic and diagnostic indicators in tumors.
