A review of artisanal cheese making: An African perspective
Authors: Nyamakwere F. , Esposito G. , Dzama K. , Raffrenato E.
Published: August 2021

Artisanal cheeses and other fermented milk products have long been part of the diet of African rural communities. Cheese is a source of nutrients that are essential to the development and growth of children in rural areas, where intake of amino acids, vitamin A, vitamin B12, calcium, phosphate, and polyunsaturated fatty acids may be limited. Wara, Karish, Ayib, Takammart, Wagashi, Domiati, and Ras are prominent cheeses of African origin. Artisanal cheese making should be expanded to improve people’s nutritional status at low cost, stimulate the local economy, and empower small-scale farmers. This review firstly gives an overview of artisanal cheese production and consumption, and evaluates opportunities and challenges, while focusing on an African perspective. Secondly, it provides an insight into strategies that could improve cheese making at small-scale level. Possible areas of research and knowledge gaps are highlighted, particularly ways of improving cheese quality and safety.
Effects of feeding system and pre-partum supplementation on the β-carotene status of South African Holstein cows
Authors: Erasmus L.J. , Machpesh G. , Coertze R.J. , Du Toit C.J.L.
Published: August 2021

AbstractThe objectives were to investigate the β-carotene status of dairy cows under various production systems, and to determine the effect of pre-partum β-carotene supplementation on their post-partum β-carotene status. Ten farms were selected from each of the three  production systems, namely pasture-based, hay-based total mixed ration (TMR) and silage-based TMR. Twenty cows per farm were sampled in each system, and blood plasma β-carotene concentration was determined with a portable spectrophotometer (n = 200 cows per system). Mean blood β-carotene concentrations of pasture-fed cows were 5.54 mg/L, and were higher (P <0.05) than concentrations of cows on hay-based (2.98 mg/L) and maize silage-based TMR systems (1.71 mg/L); in β-carotene status, therefore, these systems were optimal, marginal, and deficient, respectively. In the second experiment, 10 cows received a hay-based control TMR, and 10 were  supplemented with 1.2 g/day of β-carotene pre-partum from day -56 to calving and monitored until day 56 postpartum. The supplemented cows were in optimal β-carotene status until calving, with a minor carry-over effect until 10 days post partum, and then declined gradually in status until they needed supplementation. The β-carotene status between the groups differed from three weeks pre-partum to two weeks post partum, with the control group being marginal to deficient from three weeks pre-partum onwards. Forage type and its β-carotene content play a major role in the β-carotene status of cows and more research is needed on the potential storage and mobilization of β-carotene in cows.
The MAMI Care Pathway Package: A resource to support the management of small and nutritionally at-risk infants under six months of age and their mothers (MAMI)
Authors: Grey Kelsey , Brennan Eilise , Kerac Marko , McGrath Marie
Published: August 2021

Globally, millions of infants under six months (u6m) are small and nutritionally at-risk, but many do not get the care they need to survive and thrive. Although the 2013 World Health Organisation (WHO) guidelines for severe malnutrition management recommend outpatient care for clinically stable infants u6m, most national guidelines still recommend inpatient care for all infants u6m. To help put the WHO recommendations into action, the MAMI Global Network has developed the MAMI Care Pathway Package – a resource to facilitate the screening, assessment, and management of small and nutritionally at-risk infants u6m and their mothers. The Package uses an integrated care pathway approach and is designed to embed within and support Integrated Management of Childhood Illness (IMCI). By improvingcontinuity of care and facilitating patient management, the MAMI Care Pathway Package aims to help health workers improve outcomes for infants and mothers worldwide while also simplifying their care.
Adaptive Directional Cubic Convolution for Integrated Circuit Chip Defect Image Interpolation
Authors: Chao Yuan , Ma Chengxia , Shan Wentao , Feng Junping , Zhang Zhisheng
Published: August 2021

An adaptive directional cubic convolution interpolation method for integrated circuit (IC) chip defect images is proposed in this paper, to meet the challenge of preserving edge and texture information. In the proposed method, Otsu thresholding technique is employed to distinguish strong edge pixels from weak ones and texture regions, and estimate the direction of strong edges, adaptively. Boundary pixels are pre-interpolated using the original bicubic interpolation method to help improve the interpolation accuracy of the interior pixels. The experimental results of both classic test images and IC chip defect images demonstrate that the proposed method outperforms the competing methods with better edge and texture preservation, interpolation quality, more natural visual effect of the interpolated images and reasonable computational time. The proposed method can provide high quality IC chip images for defect detection and has been successfully applied on practical vision inspection for IC chips

Published: August 2021

Objective: To evaluate the risk factors, chromosomal abnormalities and additional anomalies of cases diagnosed with fetal neural tube defects (NTDs).

Material and Method: The data of cases diagnosed with fetal NTDs between January 2016 and August 2020 with fetal NTD were retrieved from the hospital database. Only patients whose diagnosis confirmed after pregnancy termination and have a genetic test were included in the study.  The family and antenatal history of patients included maternal age, maternal education level, diabetes mellitus, exposed to teratogenic drugs, smoking, and folic acid intake before or during the first trimester, siblings with a congenital abnormality, consanguinity, and AFP MOMs (alpha-fetoprotein, multiple of median) was obtained. Also, the type and level of NTDs and additional anomalies were noted. The data were evaluated using version 23.0 (SPSS Inc., Chicago, IL, USA).

Results: During the study period, a total of 68 patients who met the study criteria were included in the study. A total of 27 patients diagnosed with spina bifida, 24 patients with anencephaly and 17 patients with encephalocele. The most anomalies resulted from NTDs was hydrocephaly and pes equinovarus. The most detected chromosomal abnormality was trisomy 13 (3 out of 7), and the most additional anomaly was the cleft lip and palate and detected in 4 (5.88%) patients. Pregestational DM was seen in 12/68 of pregnancies with fetal NTD.

Conclusions

The rate of additional anomalies and chromosomal abnormalities in cases diagnosed with fetal NTDs is high. Thus, a detailed ultrasonographic examination and genetic tests of fetuses with NTD is essential. The pregnancies complicated with pregestational DM have an increased risk for fetal NTD.
Face-to-Face Nursing Promotion of Cardiac Rehabilitation
Authors:   , Whitaker Maria
Published: August 2021

Practice Problem: The burden of cardiovascular disease is rising at global and national levels, and cardiac rehabilitation is recognized as one of the most beneficial and cost-effective strategies to manage it. One significant problem globally, nationally, and locally is the low numbers of eligible patients who enroll in cardiac rehabilitation. PICOT: In patients with isolated coronary artery bypass graft (CABG) (P), how does face-to-face nursing promotion of cardiac rehabilitation (I) compared to the patients who do not have face-to-face nursing promotion (C), affect the percentage of patients enrolling in cardiac rehabilitation after discharge (O) within 8 weeks (T)? Evidence: The evidence used to guide this project included the need for a healthcare organization to have a systematic process for cardiac rehabilitation enrollment, face-to-face nursing promotion, improvement of the healthcare team’s knowledge about cardiac rehabilitation, and identification of patient barriers that hinder cardiac rehabilitation enrollment. Intervention: A systematic approach for cardiac rehabilitation was developed using the interprofessional team. After the healthcare team received standardized education, nurses in various roles provided face-to-face promotion, the ARNPs endorsed cardiac rehabilitation, and the care managers addressed barriers. Outcome: The cardiac rehabilitation enrollment rate increased by 16% among all patients admitted with an isolated CABG on the pilot unit. Conclusion: Implementation of face-to-face nursing promotion, ARNP endorsement, and reducing barriers were clinically significant in increasing the cardiac rehabilitation enrollment rate.

La formación del docente en geografía y las actuales exigencias socio-educativas en Venezuela
Authors: Paradas Pérez Luis Alberto
Published: August 2021

La finalidad del trabajo es reseñar los pasos seguidos en la investigación que condujo a proponer un modelo teórico para orientar la formación de docentes en Geografía. El problema es que la escuela ha dejado de ser la instancia esencial en la transferencia del conocimiento; ella debería hacer énfasis en el sujeto como centro de todo proceso escolar y educativo. La Reforma Educativa de 1996 generó dos modelos opuestos, un desfase entre las dos primeras etapas de Educación Básica, concebidas con el constructivismo, y la Tercera Etapa de Educación Básica, junto con Educación Media, mantenidas en el conductismo. La formación del docente especialista en Geografía minimiza contenidos basados en cotidianidad, entorno y paisaje y hace énfasis en otros de poca utilidad. Se estableció un marco teórico referencial conceptual con aportes de Kant, Vico, Piaget, Vygotski, Brunner, Ausubel, Maturana, Platón, Aristóteles, Marina, Echeverría y Legendre. El método de investigación empleado fue el Comparativo Continuo de Análisis Cualitativo de Miles y Huberman el cual explica, por la vía gráfica y el análisis del discurso, las categorías estudiadas y las relaciones que existen entre ellas para determinar el modelo final.

El cambio conceptual en la transformación de las preconcepciones en las Ciencias Naturales
Authors: Mahmud Mirna , Gutiérrez Oscar
Published: August 2021

El objetivo de esta  investigación fue determinar mediante un diseño cuasiexperimental  el efecto de la estrategia didáctica basada en cambio conceptual para la transformación de las preconcepciones en el aprendizaje de las ciencias naturales, específicamente en los conceptos calor y temperatura. El estudio se realizó en la asignatura de Diseño Experimental, con una población de 40 estudiantes de la especialidad de Física del Instituto Pedagógico Luis Beltrán Prieto Figueroa de Barquisimeto. Los sujetos en estudio estuvieron conformados por dos grupos intactos que aleatoriamente se escogieron como un grupo experimental y control respectivamente. Al primero se le aplicó una estrategia didáctica basada en Cambio Conceptual y al segundo una Estratega Didáctica Tradicional de Enseñanza. El efecto de ambas estrategias fue comparado mediante el estadígrafo t de Student para muestras independientes, y el resultado obtenido (tp=11,9 >  tc =2,13) permitió rechazar la hipótesis nula y aceptar la hipótesis alterna que planteaba que en los estudiantes a los cuales se les aplicaba el tratamiento con la estrategia de cambio conceptual se producirían cambios significativos en las calificaciones obtenidas en la posprueba sobre las preconcepciones de calor y temperatura en comparación con los que recibirán el tratamiento con la estrategia tradicional. Por lo tanto, se concluye que la aplicación de Estrategia Didáctica basada en Cambio Conceptual permite mejorar la transformación de las preconcepciones  sobre calor y temperatura  que tienen los estudiantes de Física en este nivel educativo.
Agentes pedagógicos inteligentes y ambientes colaborativos como recursos estratégicos de aprendizaje
Authors: Talavera Pereira Rosalba , Marcano Aular Yelitza
Published: August 2021

Los agentes pedagógicos inteligentes actualmente son recursos que actúan para resolver problemas, realizar inferencias y determinar acciones que involucren el manejo de tareas, técnicas de comunicación, de conocimiento y colaboración en diferentes áreas del aprendizaje, formación y educación, entre otros. Ahora bien, el planteamiento de este artículo esta enfocado en brindar una reflexión teórica producto de la revisión documental,  del cual se derivaron los siguientes resultados: es propicio el uso de  los agentes pedagógicos inteligentes en ambiente de aprendizaje colaborativos, por otro lado, una de sus fortaleza es que ofrecen igual oportunidad a los estudiantes para desarrollar su crecimiento individual y grupal y su mayor debilidad està centrada en que las respuestas y explicaciones que proporciona el agente, vienen dadas a que éste comprenda las características y requerimientos de cada estudiante. En tal sentido para apoyar la labor del docente, se proponen una serie de estrategias  aplicadas en ambas perspectivas.

Preliminary Studies on Efficacy of Prolonged Nasal Cul-De-Sac with High Pressure Speech Acts (P.i.N.C.H.) on Hypernasality
Authors: Fisher Helene
Published: August 2021

Prolonged Nasal Cul-De-Sac with High Pressure Speech Acts (P.i.N.C.H.), a technique to treat hypernasality, was developed upon the basis of four physiological principles of velopharyngeal function. Preliminary experimental and clinical studies were conducted to determine the efficacy of P.i.N.C.H. in decreasing nasalance in 5 non-cleft palate subjects with velopharyngeal incompetence over a 3-week to 22 month period of time. Results revealed statistically significant decreases in nasalance for posttreatment measures immediately after treatment as well as over several months. It was concluded that P.i.N.C.H. warrants further investigation.
Recruiting and Retaining Allied Health Professionals in Rural Australia: Why is it so Difficult?
Authors: Struber Janet
Published: August 2021

Rural communities in Australia have particular health needs, and the recruitment and retention of Allied Health Professionals (AHPs) is a significant concern. Despite the increasing number of AHPs being trained, vacancy and attrition rates in rural areas continue to rise. Professional and social isolation combined with rapidly changing health service delivery structures are identified as major deterrents to long-term rural practice. While strategies are now being implemented, endeavours to resolve the issues lag well behind initiates offered to Medical and Nursing staff. Given the wealth of political, professional and health related issues underlying the recruitment and retention of AHPs to rural areas, total resolution of this issue may not be possible. A unified approach by AHPs combined with concerted effort and collaboration on the part of all the stakeholders may, however, allow management at a level required to sustain a viable rural AHP workforce.
Physical Therapists' Evaluation of the Trunk Flexors in Patients With Low Back Pain.
Authors: Rone-Adams Shari , Shamus Eric , Hileman Melissa
Published: August 2021

Study Design: This study utilized a single blind design in the observation of 20 initial low back evaluations performed by physical therapists. The physical therapists were blinded to what the researchers were observing. Objective: The objective of this study was to determine whether or not physical therapists were quantifying the strength of trunk flexors when the patient’s chief complaint was low back pain. Background: The literature has shown that there is a relationship between back pain and decreased strength in the abdominal muscles. Therefore, it appears important for physical therapists to evaluate the abdominal muscles in patients with low back pain. Methods and Measures: Twenty physical therapists participated in the study. The researchers observed if trunk flexor strength was quantified during the initial evaluation of 20 patients with low back pain. Following the observation, each physical therapist was given a questionnaire and asked to comment on their evaluation of the trunk flexors. Results: Of the evaluations that were observed, 15% of the physical therapists evaluated the trunk flexors and 85% did not. Conclusion: This study demonstrated that therapists did not consistently quantify abdominal strength when treating patients with low back pain.

Online Learning in Nutrition and Dietetics: Student Performance and Attitudes
Authors: Upton Dominic
Published: August 2021

Context: Behavioural studies can form an essential component of the Nutrition and Dietetics undergraduate degree. Aims: This study aimed to firstly produce on-line teaching material in Behavioural studies suitable for undergraduate Nutrition and Dietetic students. Secondly, to explore students’ views on the online material, and record their performance when taught through this innovative method. Methods: Nutrition and Dietetics students completed an online health psychology/sociology module and their performance compared to students who completed a traditional lecture based course. Student evaluations of the online course were also recorded. Findings: Results suggested that students taught through on-line medium performed no differently to those taught through “traditional lectures”. Students appeared to enjoy the material although there was some reluctance to develop an independent learning style. Conclusion: It was apparent that material has to be developed that can both engage and motivate learners, thereby further developing independent learning, and that this may have to be tailored dependent on a number of student factors.
Concurrent Validity Of Borg’s Rating Of Perceived Exertion In African-American Young Adults, Employing Heart Rate As The Standard
Authors: Karavatas Spiridon , Tavakol Kamran
Published: August 2021

Borg’s Rating of Perceived Exertion (RPE) is a simple and convenient method of monitoring exercise intensity; however, the correlation between RPE and heart rate (HR) is not always consistent. This pilot study examined the criterion-based validity of RPE versus heart rate. Twelve fasting, healthy African-American volunteers at ages of 21-41 years performed a supervised, 45-minute brisk walk test on a treadmill over three consecutive days. Throughout the test, each subject was asked the RPE every five minutes. The subjects' heart rates were monitored continuously and recorded every minute. The overall correlation coefficient, r, between RPE and HR for all data sets (N=360) was 0.58. The "r" values for males and females were 0.60 and 0.56, respectively. The analysis revealed that the correlation between RPE and HR was not as strong as previously reported, and that gender influenced the correlation. Also, RPE may be safely used to assess the exercise intensity in healthy subjects
The Predictive Value of Gross Motor Development, Posture and Upper Quadrant Stability for TMD in Children and Young Adults: A Preliminary Study
Authors: Nof Leah , Rosenthal Rebecca
Published: August 2021

Purpose: This study investigated the relationship of onset of independent walking, upper quadrant stability and head posture and their value as predictors of temporomandibular dysfunction (TMD). Method: Quasiexperimental nonequivalent posttest design study of forty-seven subjects, ages 9 to 29, who were symptomatic or asymptomatic for TMD. Age of independent walking was recorded; temporomandibular joint (TMJ) function was examined; strength of upper quadrant musculature was tested; scapulae distances from corresponding spinous processes were measured; and standing posture was assessed. Results: Significant differences in age of onset of walking, rhomboid strength, scapulae distance from the spinous processes, and head posture were found between groups of subjects presenting with symptomatic and asymptomatic TMD. Age of walking, scapulae distance and forward head posture correctly predicted presence or absence of TMD in 81% of study subjects.Conclusions: Early independent walking may negatively affect scapular stabilization, contributing to excessive forward head posturing, and later onset of TMD. Further research is indicated.

We investigate the relations between the proof lines of non-minimal tautologies and its minimal tautologies for the Frege systems, the sequent systems with cut rule and the systems of natural deductions of classical and nonclassical logics. We show that for these systems there are sequences of tautologies ψn, every one of which has unique minimal tautologies φn such that for each n the minimal proof lines of φn are an order more than the minimal proof lines of ψn.
ON LOCALLY-BALANCED 2-PARTITIONS OF BIPARTITE GRAPHS
Authors: Gharibyan Aram H. , Petrosyan Petros A.
Published: August 2021

A \emph{$2$-partition of a graph $G$} is a function $f:V(G)\rightarrow \{0,1\}$. A $2$-partition $f$ of a graph $G$ is a \emph{locally-balanced with an open neighborhood}, if for every $v\in V(G)$, $\left\vert \vert \{u\in N_{G}(v)\colon\,f(u)=0\}\vert - \vert \{u\in N_{G}(v)\colon\,f(u)=1\}\vert \right\vert\leq 1$. A bipartite graph is \emph{$(a,b)$-biregular} if all vertices in one part have degree $a$ and all vertices in the other part have degree $b$. In this paper we prove that the problem of deciding, if a given graph has a locally-balanced $2$-partition with an open neighborhood is $NP$-complete even for $(3,8)$-biregular bipartite graphs. We also prove that a $(2,2k+1)$-biregular bipartite graph has a locally-balanced $2$-partition with an open neighbourhood if and only if it has no cycle of length $2 \pmod{4}$. Next, we prove that if $G$ is a subcubic bipartite graph that has no cycle of length $2 \pmod{4}$, then $G$ has a locally-balanced $2$-partition with an open neighbourhood. Finally, we show that all doubly convex bipartite graphs have a locally-balanced $2$-partition with an open neighbourhood.

INVESTIGATION OF THE INFLUENCE OF AN INTERMEDIATE HINGE SUPPORT IN THE PROBLEM OF BENDING OF AN ELASTICALLY RESTRAINED ORTHOTROPIC BEAM
Authors: Stepanyan Seyran P.
Published: August 2021

In this paper, based on the refined theory of orthotropic plates of variable thickness, a system of differential equations is obtained for solving the problem of bending of an elastically restrained beam with an intermediate condition. The beam thickness is constant and is subject to a uniformly distributed load. The effects of transverse shear are also taken into account. Passing to dimensionless quantities, an analytical closed solution is obtained. The question of the influence of changing the place of application of the intermediate condition on the solution is discussed. Depending on the location of the hinge bearing, the question of optimality was posed and resolved according to the principle of minimum maximum deflection. The results are presented in both tabular and graphical form. Based on the results obtained, appropriate conclusions are drawn.

Hold
Authors: Smith Penda
Published: August 2021

This poem is inspired by Christina Sharpe's In the Wake: On Blackness and Being and Zong! by M NourbeSe Phillip. I am remembering this summer's protest against police brutality and in conjunction with Sharpe's theory on atemporality, I merge being on the streets with Zong!s incantations of Translatlantic Slavery. This poem is the genesis of what I hope to be a litany of interrogations that explores the nuances around holding, the hold, and held.

Authors: S Santha Subbulaxmi , G Arumugam
Published: August 2021

Skewed data distribution prevails in many real world applications. The skewedness is due to imbalance in the class distribution and it deteriorates the performance of the traditional classification algorithms. In this paper, we provide a Grey wolf optimized K-Means cluster based oversampling algorithm to handle the skewedness and solve the imbalanced data classification problem. Experiments are conducted on the proposed algorithm and compared it with the benchmarking popular algorithms. The results reveal that the proposed algorithm outperforms the other benchmarking algorithms.

Abstract –Today Security issue is the topmost problem in the cloud computing environment. It leads to serious discomfort to the Governance and end-users. Numerous security solutions and policies are available however practically ineffective in use. Most of the security solutions are centered towards cloud technology and cloud service providers only and no consideration has been given to the Network, accessing, and device securities at the end-user level. The discomfort at the end-user level was left untreated. The security of the various public, private networks, variety of devices used by end-users, accessibility, and capacity of end-users is left untreated. This leads towards the strong need for the possible modification of the security architecture for data security at all levels and secured service delivery. This leads towards the strong need for the possible adaption of modified security measures and provisions, which shall provide secured hosting and service delivery at all levels and reduce the security gap between the cloud service providers and end-users. This paper investigates the study and analyze the security architecture in the Cloud environment of Govt. of India and suggest the modifications in the security architecture as per the changing scenario and to fulfill the future needs for the secured service delivery from central up to the end-user level.

Assessing the Climate Change Adaptations of Upland Farmers: A Case of La Trinidad, Benguet, Philippines
Authors: Alfonso Gerryc P.
Published: August 2021

Adaptation to climate change impacts varies from country to country. It is difficult to capture the concept of adaptations because it includes government policies and the behavior of farmers. Undertaking regional and local assessments of adaptations is still informative because it serves as baseline data for government and other institutions in supporting the needs of the farmers to adapt to the impacts of climate change. Thus, the study aims to look at the institutional supports availed and needed by farmers for climate change adaptation and assess their cost, effectiveness, institutional capacity, and acceptability. Personal interview and Focus Group Discussion complemented by various data gathering techniques was done to provide ample description and understanding of the sources, cost, effectiveness, institutional capacity, and acceptability of the climate change adaptations of farmers in La Trinidad, Benguet. Various institutional supports were given to the farmers but not equally and equitably distributed to the farmers. Almost all of the adaptations were effective, the cost and degree of institutional capacity needed are low but highly acceptable to the farmers.
Cultural and Historical Preservation through Onomastic Materials: A Case of Toponyms and Anthroponyms in Kinyarwanda
Authors: Kayigema Jacques Lwaboshi
Published: August 2021

Proper names, also linguistically called toponyms and anthroponyms, embed extensive sociolinguistic, cultural, and historical aspects in the life of any nation. Thus, they have caught the researcher’s attention because of the cultural and historical heritage they preserve in the context of language contact. From one place to another, and one specific period to another, anthroponyms and toponyms offer a wide range of research because of the scientific curiosity researchers have as to know why the name of a person or place exists, where it comes from, who named it, and when it was named so. In other words, the research is carried within spatial and temporal scope. Anthroponymy is the study of proper names of human beings, both individual and collective, while toponymy is the study of proper names of places.
This paper aims at showing how place and person names embed cultural and historical features necessary to understand, explain, and preserve a people’s culture and history for a given period. The method used to research this topic is descriptive and it is based on the materials observed from various sources such as street names, hoardings, individual names, just to name a few.
Therefore, this study focuses on specific topologies and periods, i.e. names denoting locations where the Rwandan territory has extended in the precolonial, colonial, postcolonial periods, and post-genocide periods.
Migrantes Potenciales Mexicanos: Sus Motivaciones y Actitudes hacia la Aculturación
Authors: Domínguez Espinosa Alejandra , Polo Velázquez Alma
Published: August 2021

El hecho de que en algunas regiones de México la situación socioeconómica es precaria, con expectativas ocupacionales o laborales limitadas pocas oportunidades de tener un nivel socioeconómico confortable, además de la proximidad que tiene México con Estados Unidos, influencia la decisión de migrar hacia este último país. La manera en que las personas probablemente acepten o rechacen algunos aspectos de la nueva cultura puede influenciar esta decisión. Con base en lo anterior, el objetivo principal del presente trabajo es explorar qué tipo de motivaciones y actitudes hacia la aculturación están presentes en migrantes potenciales mexicanos. Utilizando una muestra no probabilística de 580 adolescentes de dos estados de la República Mexicana (de áreas con altos niveles de migración) se evaluaron las cuatro actitudes de aculturación propuestas por Berry (1992) en un formato de viñetas. Los resultados indican que la actitud más frecuente es la integración; sin embargo, el hecho de que el resto de las actitudes no sigan la orientación esperada resulta interesante.

Published: August 2021

El objetivo de esta investigación fue predecir la infidelidad sexual y emocional de hombres y mujeres a partir de un conjunto de características biológicas, psicológicas y socioculturales que involucran los patrones sexuales de la persona, conducta y personalidad sexual; su orientación socio-sexual, la satisfacción con la relación primaria y de sus conceptos y actitudes hacia la infidelidad. Para lograr este objetivo se conformó una muestra no probabilística de 151 hombres y 183 mujeres, todos los participantes tenían una relación de pareja heterosexual y 30 años en promedio. Se realizaron análisis de regresión múltiple por pasos. En general los análisis de regresión mostraron que las variables que predicen la infidelidad sexual de los hombres y de las mujeres son las variantes sexuales, la conceptualización positiva de la infidelidad y los motivos asociados a la personalidad. La infidelidad emocional de hombres y de mujeres fue predicha también por la conceptualización positiva de la infidelidad y por una personalidad sexual abierta.
