Executive function assessment: Adaptation of the Amsterdam executive function inventory using Spanish first-year university students from two knowledge areas
Authors: Escolano-Pérez Elena , Romero-Galisteo Rita Pilar , Rodríguez-Medina Jairo , Gálvez-Ruiz Pablo 
Published: August 2022

Objective
Many university students have difficulties in adapting to autonomous learning due to executive functioning deficits. In the Spanish university context, there is a lack of reliable validated instruments for the evaluation of executive functioning. In this sense, the aim of this research is to present the process of adaptation and validation of the Amsterdam Executive Function Inventory (AEFI) for the evaluation of executive functioning in the Spanish context.

Methods
This study integrates two sequential processes: questionnaire translation and back-translation, and evaluation of the psychometric properties (exploratory and confirmatory factor analysis were conducted), reliability, validity and multigroup analysis to identify factorial invariance. An online questionnaire was used for data collection and R package lavaan software was administered to a sample of 519 first-year university students (270 females and 249 males).

Results
The exploratory factor analysis evidenced an interna structure of three factors with adequate internal consistency (Cronbach’s alpha higher than 0.70), endorsed in the confirmatory factor analysis that indicated an adequate goodness-of-fit-indexes for the model. The composite reliability showed values between 0.74 and 0.82, and the convergent (average variance extracted values ranged from 0.50 to 0.61) and discriminant validity were adequate. A multigroup-analysis showed the invariance factorial through the difference in the RMSEA, CFI and TLI index, performed both in the model comparison according to gender and academic disciplines.

Conclusion
The AEFI adapted for Spanish has practical implications for the management of university students, as it can facilitate the improvement of university policies designed to foster the development of executive functions, specifically in first-year students.
Acoustic space in narration from the perspective of production
Authors: Fu Xiuyan , Cai Fang 
Published: August 2022

Abstract
A major mark of the progress of human society is its transition from the production of things in space to the production of space itself. Oral narrative covers a certain range of space with sound, and physical spaces such as theaters, cinemas, and concert halls accommodate various forms of narrative communication. Drama was the most popular form of mass communication in the pre-industrial age, and its performance required a “sound wall” around the theater to keep people focused. Comment and discussion were both significant forms of narrative consumption. Some consumers who paid more attention to “being seen” even regarded the communication arena as a social platform. In present times, commentary subtitles (Danmaku in Japanese) pop up on computer screens from time to time to make consumers feel as if they are chatting with people while watching. “Chatting” in social media groups also belongs to interaction in virtual space. Surround sound in the cinema wraps the audience and screen into a unifying auditory space, blurring or even eliminating the boundaries between them. Narrative has been an act of producing acoustic space from the very beginning. Nowadays, people adopt more abundant narrative means yet still rely on the imitation of auditory communication.
Global stability for a SEIQR worm propagation model in mobile internet
Authors: Zhang Liang , Liu Pengyan 
Published: August 2022

Abstract
Recently, propagation models of worms in the mobile environment are drawing extensive attention, particularly in the Wi-Fi scenario. Considering that worm-free equilibrium is exponential convergent means that the propagation time and control time of worms are much shorter than for other asymptotic convergence. Besides, the global asymptotic stability of the endemic equilibrium is more important than the local asymptotic stability, which reflects the more global qualitative behavior of the worm propagation. In this paper, we discuss the global dynamics of SEIQR worm propagation model in mobile internet proposed by Xiao et al. [X. Xiao, P. Fu, C. Dou, Q. Li, G. Hu, and S. Xia, “Design and analysis of SEIQR worm propagation model in mobile internet,” Commun. Nonlinear Sci. Numer. Simulat., vol. 43, pp. 341–350, 2017] to improve and complement the related results. Through a series of mathematical derivations, sufficient conditions are derived to ensure the global exponentially stability of worm-free equilibrium, and the exponential convergent rate can be unveiled. Then, by using the classical geometric approach, it is shown that the endemic equilibrium is globally asymptotically stable and the system is persistent when R
0 > 1. Moreover, numerical simulations are given to demonstrate our theoretical results.

mm2 remain out of reach even in the visible frequencies. In this work, a novel hot-electron-based, non-trench-type photodetector exploiting pure photoexcitation in a thin aluminum (Al) film and leaky plasmonic modes at and between its heterojunctions is proposed, analyzed, and experimentally demonstrated. Combining diffracted-order-resolved analytical analysis and numerical computations unravels the optical absorption mechanism of the innovative design. Leaky surface plasmon resonance (with leakage radiation into the air) produced by a propagating diffracted order and quasibound supermodes (with power leakage via coupled gap plasmon polariton and bound surface plasmon polariton modes) excited by evanescent diffracted orders are shown to significantly contribute to the absorptance in the preferred thin Al film where hot electrons are generated. At 638.9 nm and electric bias −0.9951 V, the measured per-unit-area responsivity, detectivity, and the external quantum efficiency reach 298.1444 μA/mW/mm2, 4.3809 × 109 cm Hz1/2/W, and 2.6878%, respectively, from an active area of 4.6457 × 10−2 mm2. The performance is among the best of those previously reported operating at similar wavelengths and biases. The RC time constant is estimated to be about 1.673 μs from the current-voltage measurements. The physical insight into the innovative, experimentally demonstrated device could lay the groundwork for the practical use of low-voltage, metal-based photodetection.
Study of baryogenesis in the framework of Hořava–Lifshitz cosmology with Starobinsky potential
Authors: Chakraborty Gargee , Chattopadhyay Surajit 
Published: August 2022

Abstract
Motivated by the work of Paliathanasis et al. (A. Paliathanasis and G. Leon, “Cosmological solutions in Hořava–Lifshitz scalar field theory,” ZnA, vol. 75, p. 523, 2020), this work reports the baryogenesis in Hořava–Lifshitz cosmology by taking the background evolution as modified Chaplygin gas and modified holographic dark energy. The Starobinsky potential has been selected to initiate the study. The scalar field and its potential have been reconstructed and found to be consistent with the universe’s expansion. The quintessence behaviour of equation of state parameters has been observed for both cases. Finally, baryogenesis has been studied in both cases. The baryon entropy ratio attained the observed value. It is also well explained that either the model will achieve an equal number of baryon and antibaryon densities or will satisfy the Generalized Second Law of Thermodynamics.

Published: August 2022

Abstract
Durch den Fortschritt beim selektiven Laserschmelzen (SLM-Verfahren) ist es möglich, Hilfsmassendämpfer in die Struktur einer Werkzeugmaschine zu integrieren. Die Eigenfrequenz des mit dem SLMVerfahren hergestellten Dämpfers muss hierfür einstellbar sein. Dies wurde allerdings noch nicht ausreichend erforscht. In diesem Beitrag werden Dämpfer ausgelegt und ihre ersten Eigenfrequenzen gemessen. Auf Basis der Messergebnisse wird ein Simulationsmodell des neu ausgelegten Dämpfers entwickelt. Mit diesem Simulationsmodell ist die Einstellung der ersten Eigenfrequenz in der Auslegungsphase ohne physikalischen Prototyp möglich.

Ready or Not, Here I Come: A Scoping Review of Methods Used to Assess Player Readiness Via Indicators of Neuromuscular Function in Football Code Athletes
Authors: Guthrie Brian , Jagim Andrew R. , Jones Margaret T. 
Published: August 2022

ABSTRACT
A scoping review methodology was used to assess player readiness via indicators of neuromuscular function in response to training load. Literature search included PubMed, Web of Science, SportDiscus, and CINAHL. Search strategy was based on Population-Concept-Context framework evaluating football code athletes with the focus on player readiness in the context of longitudinal monitoring across quantified training loads with an emphasis on neuromuscular function. Demographics, frequency of data collection, methods of monitoring readiness, neuromuscular function, duration of monitoring period, and quantification of training loads were reported. Authors independently reviewed articles and, in the case of disagreement, a vote determined inclusion. The sports of rugby (n = 13) and soccer (n = 11) were most frequently examined, followed by Australian Rules Football (n = 6) and American Football (n = 1). The most common methods assessed systemic readiness with the primary focus on jump and sprint testing. Findings identified limited evidence supporting structural and tissue-specific monitoring tools. Player readiness assessment strategies have evolved with advances in technology and analytics. It is recommended that future research focus on a variety of populations, including youth and women athletes. This review is the first to summarize methods of assessing player readiness using indicators of neuromuscular function in football code athletes.
EXTENSIVE EXPERTISE IN ENDOCRINOLOGY: Osteoporosis management
Authors: Reid Ian R 
Published: August 2022

AbstractFractures occur in about half of older White women, and almost a third of older White men. However, 80% of the older individuals who have fractures do not meet the bone density definition of osteoporosis, suggesting that this definition is not an appropriate threshold for offering treatment. Fracture risk can be estimated based on clinical risk factors with or without bone density. A combination of calculated risk, fracture history, and bone density is used in treatment decisions. Medications available for reducing fracture risk act either to inhibit bone resorption or to promote bone formation. Romosozumab is unique in that it has both activities. Bisphosphonates are the most widely used interventions because of their efficacy, safety, and low cost. Continuous use of oral bisphosphonates for &gt;5 years increases the risk of atypical femoral fractures, so is usually punctuated with drug holidays of 6–24 months. Denosumab is a further potent anti-resorptive agent given as 6-monthly s.c. injections. It is comparable to the bisphosphonates in efficacy and safety but has a rapid offset of effect after discontinuation so must be followed by an alternative drug, usually a bisphosphonate. Teriparatide stimulates both bone formation and resorption, substantially increases spine density, and reduces vertebral and non-vertebral fracture rates, though data for hip fractures are scant. Treatment is usually limited to 18–24 months, followed by the transition to an anti-resorptive. Romosozumab is given as monthly s.c. injections for 1 year, followed by an anti-resorptive. This sequence prevents more fractures than anti-resorptive therapy alone. Because of cost, anabolic drugs are usually reserved for those at very high fracture risk. 25-hydroxyvitamin D levels should be maintained above 30 nmol/L, using supplements if sunlight exposure is limited. Calcium intake has little effect on bone density and fracture risk but should be maintained above 500 mg/day using dietary sources.

Published: August 2022

Abstract

Background and aim
In the last two decades, the proportion of internet users has greatly increased worldwide. Data regarding internet addiction (IA) are lacking in Africa compared to other continents. This systematic review and meta-analysis aimed to estimate the pooled prevalence of IA in African countries.

Methods
We systematically sought relevant articles in PubMed/MEDLINE, EMBASE, PsycINFO and Cochrane database published before September 25, 2021. The risk of bias was assessed using the Joanna Briggs Institute tool, and we estimated the pooled prevalence of IA using a random-effects meta-analytic model. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

Results
We included 22 studies (13,365 participants), and collected data from Egypt, Ethiopia, Morocco, Nigeria, South Africa, Tanzania and Tunisia between 2013 and 2021. The mean age of participants ranged from 14.8 to 26.1 years, and the most used tool for IA screening was the Young's 20-item Internet Addiction Test. The pooled prevalence rate of IA was 40.3% (95% CI: 32.2%–48.7%), with substantial heterogeneity. The pooled prevalence for Northern Africa was 44.6% (95% CI: 32.9%–56.7%), significantly higher than the prevalence in sub-Saharan Africa, which was 31.0% (95% CI: 25.2%–37.1%). The risk of bias was moderate for most studies, the certainty was very low, and we found no publication bias.

Discussion and conclusions
Four in every ten individuals was considered to have IA in Africa. Further research with methodological optimization seems needed, especially for IA screening tools and the representativity of some subregions.
Evaluation of zero-stress temperature and cracking temperature of high performance concrete at early ages
Authors: Li Liang , Dabarera Arosha , Dao Vinh 
Published: August 2022

AbstractAssessing the risk of cracking of high performance concrete induced by restrained volume changes from early ages is of considerable significance. To estimate and control such cracking risk of high performance concrete, two characteristic temperatures, namely zero-stress temperature (Tz) and cracking temperature (Tx) are crucial. In this study, the two temperatures are investigated in-depth by both theoretical analysis and experimental studies. For predicting the evolutions of Tz and Tx from early ages, rigorous yet practical models are proposed, which crucially take the visco-elastic behaviour of concrete into account. The reliability and predictive capability of the proposed models are demonstrated through a series of comparisons between the predicted and the measured results. Based on the predicted Tz and Tx profiles, practical thermal control criteria for preventing concrete from cracking caused by restrained strain are put forward. In principle, the actual temperature (T) of concrete should be kept higher than both Tz and Tx to properly maintain the stress induced by restrained strain in compression at early ages. If T becomes lower than Tz and reduces continuously, the lower the value of T, the higher the risk of cracking of concrete induced by restrained strain. As a consequence, once the value of T reaches or becomes lower than Tx, cracking is highly likely to occur. For a given actual temperature condition, lowering Tz and Tx can mitigate the risk of the cracking of concrete. Finally, effective measures for such lowering of Tz and Tx are also proposed.

Published: August 2022

Strongyloides stercoralis es un nemátodo que se caracteriza por causar una infección intestinal, usualmente asintomática, en pacientes inmunocompetentes. Sin embargo, en aquellos que viven con VIH, y de acuerdo con su estado inmune, puede generar un síndrome de hiperinfección con complicaciones diversas por diseminación a diferentes órganos.
Se presenta el caso de un paciente de 30 años con diagnóstico de novo de infección por el virus de la inmunodeficiencia humana, con documentación de enfermedad linfoproliferativa. En los estudios complementarios se documenta la presencia de Strongyloides stercoralis de manera inusual en la médula ósea. A pesar de contar con un recuento de linfocitos T CD4+ mayor a 400 células/mL y de haberse iniciado el manejo para esta condición con ivermectina, el paciente fallece por un estado séptico asociado al síndrome de hiperinfección, por lo cual se considera que este es un caso inusitado que obliga al clínico a tener en cuenta la presencia del nemátodo en pacientes que viven con VIH.

Objective: The current study was conducted to investigate the effectiveness of group counseling on quality of life and symptom severity among university students with Premenstrual Syndrome. Method: After filling in PSST and participating in SCID-CV, 120 students answered the demographic and WHOQOL questionnaires. Using classified random sampling, they were divided into control and intervention groups. The Intervention Group participants attended six group counseling sessions. They post-tested at two moments (immediate post-test and after one month). Results: The results of the immediate post-test indicated improvements in overall quality and in some domains (p<0.005) in the Intervention Group, and the second post-test showed an improvement in two of the domains (p<0.005). One month later, some symptoms were clearly improved in the Intervention Group (p<0.005). Conclusion: Group counseling improved the students' quality of life and severity of the Premenstrual Syndrome symptoms.

A ecoinovação, modalidade de inovação objetiva um novo patamar na busca de soluções que interfiram de maneira positiva na relação com o meio ambiente, sendo um dos caminhos que podem conduzir a sustentabilidade ambiental. Nessa perspectiva, os empreendimentos que operam o turismo sustentável enxergam na ecoinovação uma oportunidade de agregar valor e atrair novos clientes. O estudo objetivou apontar os principais determinantes de ecoinovação nos empreendimentos que desenvolvem o turismo sustentável no entorno do Riacho do Talhado da Cidade de Delmiro Gouveia, Alagoas. Para tal foram realizados estudos de múltiplos casos em três empreendimentos de turismo sustentável, considerando a localização geográfica e a relevância do turismo na geração de emprego, renda, suas diversas interações e impactos sociais. Foram verificadas as tipologias de turismo que são praticadas e realizado o enquadramento dos empreendimentos como operadores de turismo sustentável, utilizando os princípios técnicos propostos pelo Conselho Brasileiro de Turismo Sustentável – CBTS; foram apontadas as práticas de ecoinovação com a adaptação de modelos teóricos utilizados para identificar a presença e tipologia de ecoinovações; para só então apontar os principais determinantes de ecoinovações nos empreendimentos pesquisados. A coleta de dados ocorreu com entrevistas semiestruturadas. O estudo teve abordagem qualitativa, foi descritivo e exploratório, o método foi dedutivo com análise de conteúdo e observação participante. Os resultados apontaram para que as organizações pesquisadas operam o turismo sustentável, são ecoinovadores e seus fatores determinantes são similares apesar de trabalharem com tipos de turismo diferentes.

Published: August 2022

Esta pesquisa tem como objetivo propor melhorias no processo de gestão de descarte de equipamentos de informática na Universidade Federal de Rondônia (UNIR), Campus José Ribeiro Filho, considerando as premissas de TI Verde para a sustentabilidade, mais especificamente, quanto a premissa que inclui o descarte responsável. Trata-se de uma pesquisa qualitativa, de natureza aplicada, finalidade descritiva, aporte do método de pesquisa Estudo de Caso, e seus procedimentos técnicos a definem como pesquisa documental e pesquisa de campo. Os dados foram obtidos mediante entrevista semiestruturada aos servidores da UNIR lotados na Reitoria, Pró-reitorias, diretorias administrativas, diretorias dos órgãos acadêmicos e diretorias de órgãos suplementares do campus de Porto Velho. Os resultados apontam que a gestão de descarte de equipamentos eletrônicos de informática na instituição não aplica os métodos sustentáveis recomendados pela TI Verde no que se refere à destinação final dos equipamentos de informática, e que o principal instrumento de descarte do lixo eletrônico é o desfazimento de bens por meio de leilão ou doação. Observou-se que a UNIR terceirizou o serviço de impressão, e adquire equipamentos cobertos por garantia de fábrica, conforme determina a Secretaria de Tecnologia da Informação – STI, mediante a Portaria MP/STI nº 20/2016. Isto posto, percebe-se que a instituição carece de uma política de descarte para destinar os equipamentos de TI inservíveis, e que a falta de uma orientação nesse sentido praticamente impõe que o descarte de periféricos e materiais de consumo de informática seja feito de qualquer maneira conforme apurou-se com os resultados.

Published: August 2022

The concept of Internet security is studied by computer science as a safe medium for exchanging data while minimizing the likelihood of online threats. The extensive use of advanced web-based software in different industries such as education, retail, medical care, and payment systems, represents a security challenge for the programmers and an opportunity for the hackers to attack through session hijacking. Based on recent OWASP guidelines, this kind of attack is indeed one of the most frequent attacks that happens lately. Session hijacking happens as a result of poorly designed websites and a lack of security mechanisms, where the user's identity and session data are exposed. This paper will present this kind of vulnerability with the respective control mechanisms and will propose an approach for avoiding hijacking threats by using one-time cookies along with other prevention strategies.

Keywords: session hijacking, vulnerability, one-time cookies.
