Roles of Practitioners in Industry-Government Research Collaborations of South African Clothing, Textiles, Leather, and Footwear Industry: Implications for SDGs and Agenda 2063
Authors: Mbatha Sipho
Published: July 2022

This study explores the roles of industry and government in research collaborations from the context of the clothing, textiles, leather, and footwear (CTLF) industry of South Africa. This study further seeks to highlight the implications of the roles of industry and government in SDGs and the African Union Commission Agenda 2063 (hereafter Agenda 2063). Through mixed methods, this study conducted 12 interviews with participants from universities, industry, and government, as well as 22 correctly filled-in questionnaires to address the research questions of this study. The findings highlight that government performs its roles more than the industry when engaging in research collaborations in the South African CTLF industry. The implications of the roles of industry and government to the achievement of SDGs and Agenda 2063 show that the South African CTLF industry contributes to SDGs and Agenda 2063. However, the CTLF industry can contribute even more to SDGs and Agenda 2063 if they take advantage of opportunities presented by research collaborations. This study highlights science, technology and innovation policy gaps that undermine development in the CTLF industry of South Africa and negatively affect the attainment of SDGs and Agenda 2063. This study contributes new knowledge by providing empirical findings on the role of industry and government in research collaborations in the context of the CTLF industry of South Africa.

Proportionality: A Principle to be Re-evaluated in Albanian Criminal Law
Authors: Furramani Emanuela , Guli Hoti Pulina
Published: July 2022

The numerous amendments to the Albanian Criminal Code introduced over the years have continuously toughened penalties for criminal offences, raising doubts about the legislator's adherence to the proportionality principle. This issue has aroused an interest in treating proportionality as a fundamental principle of criminal law, particularly in guiding the legislator in determining appropriate punishments for criminal offences. Doctrine and jurisprudence constantly emphasize that disproportional sanctions, on the one hand, affect the re-educational and re-socialization processes, and on the other hand, they affect the discretion of the judge who, during the process of individualization of punishment, must adapt the penalty to the social danger of the criminal offence. The Albanian Constitutional Court's jurisprudence has addressed proportionality issues in a significant judgment that opened the possibility of control over the legislator's political discretion. In this regard, the Albanian Constitutional Court considered some provisions of the Criminal Code in breach of Article 17 of the Constitution because the punishment provided for the criminal offence was disproportionate, affecting in this way the re-educational process of the perpetrator. On this occasion, the Court stated that the penalty is determined by weighing the social danger of the crime and the perpetrator's level of culpability. Furthermore, the Court considered that since criminal punishment restricts fundamental rights, it should be limited to those actions or omissions that, according to the principle of proportionality, are comparable in importance to the values they safeguard.

Teachers’ Experiences in Contextualising the CAPS Curriculum Life Skills in Intermediate Phase Classrooms in the Johannesburg North Region
Authors: Frazenburg Urshula , Mabalane Valencia
Published: July 2022

The teaching and contextualisation of Life Skills as required by the Curriculum and Assessment Policy Statement (CAPS) document in the intermediate Grades 4-6 have been experienced differently by teachers. The CAPS requires teachers to make the curriculum and content relevant to the varied needs and lives of learners from different backgrounds. Resultantly, the paper is driven by three objectives a) exploration of teachers’ training background; b) understanding and implementation of the CAPS requirements, and c) teachers’ conceptualisation of contextualising Life Skills in the Intermediate Phase. The study employs the constructivist theory by Vygotsky and Piaget with the emphasis on knowledge construction, individually and socially. The study was qualitative in nature. Five Life Skills Intermediate Phase teachers were selected, observed, and interviewed using semi-structured interviews. The findings indicated that each teacher had different ways of interpreting and implementing the CAPS Life Skills. The experiences were both positive and negative due to many contextual factors that influenced the contextualisation of the content. Considering the findings, the study suggests that Life Skills should be prioritised in schools as are other subjects and be taught by specialist teachers. Further studies can be conducted to explore the impact of contextualisation of the Life Skills subject on the life of learners.

Authors: Mahlangabeza Luyolo
Published: July 2022

Human Resources Management (HRM) processes, working conditions and leadership have attracted the attention of researchers and practitioners due their importance for organisations. The study investigated the influence that HRM processes, working conditions and leadership have on retention of public service rehabilitation staff in South Africa. A quantitative research approach was adopted by distributing 82 self-constructed questionnaires of which 51 were returned. The results of the study found that HRM processes were significant and positively (r = 0.67, p < 0.05) related to staff retention. These processes included recruitment, staff development and renumeration. Leadership and changes in the working conditions will not lead to a significant retention of rehabilitation staff.  The study provides guidelines for organisations to consider retaining staff in the rehabilitation services of the healthcare sector by applying effective HRM processes.

Published: July 2022

This study aims to evaluate the level of Indigofera zollingeriana with Pennisetum purpureum cv. Mott  in ration on rumen fermentation characteristics (total VFA, NH3 and protozoa population) in vitro. The study used a completely randomized design (CRD), consisting of 5 treatments and 4 replications. P1 = 60% Pennisetum purpureum cv. Mott, P2 = 45% Pennisetum purpureum cv. Mott + 15% Indigofera zollingeriana, P3 = 30% Pennisetum purpureum cv. Mott + 30% Indigofera zollingeriana, P4 = 15% Pennisetum purpureum cv. Mott + 45% Indigofera zollingeriana, P5 = 60% Indigofera zollingeriana. All treatments received an additional 40% fine ricebran. The results showed that the level of Indigofera zollingeriana flour with Pennisetum purpureum cv. Mott had no significant effect on total VFA and NH3.  Total VFA and NH3 ranged from 131.65 mM-143.24 mM and 12.61 mM-13.74 mM, respectively. Meanwhile, the population of protozoa had a significant effect (P<0.05). DMRT further test results showed that P3 was significantly  (P<0.05) lower than P1, P2, P4 and P5. The average population of the protozoa ranged from 53.125 cells/ml to 90,625 cells/ml. Based on the results of the study, it can be concluded that the administration of Indigofera zollingeriana leaves by 30% was able to reduce the protozoan population in the rumen of FH cattle but had no significant effect on total VFA production and ammonia (NH3) concentration.

Analysis of Interior Permanent Magnet Synchronous Motor according to Winding Method
Authors: Lee Chung-Hui , Shin Hui-Seong , Kim Ki-Chan
Published: July 2022

In this paper, the hairpin method is applied to an Electric Vehicle (EV) driving motor with a stator winding designed with a round copper wire. The hairpin method is a method to secure a high space factor by using round copper wire instead of round copper wire for the stator winding. The applicable model is a 300kW Interior Permanent Magnet Synchronous Motor (IPMSM), and the cooling method is water cooling. The current density has a proportional relationship with the thermal characteristics, and in the case of a round copper wire, a method of lowering the current density by using the stator winding as a stranded wire is used. However, when the hairpin method is applied, it is expected that the current density will be low as the area of the conductor is increased, but in reality, this is not the case in most cases. Accordingly, thermal characteristics are supplemented by using oil cooling rather than water cooling as the cooling method. However, in this paper, the thermal characteristic change is analyzed using the same cooling method.

The process of applying the hairpin method from the round copper wire method is sequentially described, and changes in the main electromagnetic characteristics of the motor are compared and analyzed. Additionally, by selecting an operating point, the thermal characteristics are also analyzed. In this study, the analysis is based on the finite element method (FEM)-based electromagnetic simulation.

Testing of models of explosion protection system for highvoltage oil-filled electrical equipment
Authors: Darian Leonid A. , Polistchook Vladimir P. , Shurupov Alexey V.
Published: July 2022

Explosions of high voltage oil-filled electrical equipment (OFEE) lead to a significant material damage. These explosions occur under action of an arc discharge (AD) which arises after internal short circuit. Modernization of OFEE design and protection systems is the possible way to achieve significant reduction of potential explosion and substantial reduction of material losses. Examination of perspective explosion-proof OFEE designs and new explosion protection systems demands the effective test methods. In present work results of development and application of an arcless source of pulse pressure (ASPP) are described. In ASPP the testing impulse is produced by the jet of powder gases (JPG) which arises at the combustion of explosive materials. In this work results of experimental researches of AD in transformer oil (TO) at conditions typical for AD initial stage have been presented: current rise time was 3-5 ms, the maximum arc current was up to 30 kA, AD burning time was 3-20 ms. The energy released in AD amounted to 0.1 MJ. It was established, that electric field strength in AD column was about 0.2 kV/сm, gas producing factor in AD was 110 l/MJ, growth rate of pressure in TO was about 0.3 MPa/ms. These results allowed to create an ASPP with demanded parameters. Experiments proved that TO flow under action of AD and JPG are similar given that the same influence duration of the energy released in AD is equalled enthalpy of JPG at liquid inlet. In this work the transformer fracturing behavior after explosion has been analyzed; and the requirements for protection systems have been formulated. By means of ASPP the breadboard model tests of two well-known OFEE explosion protection methods were carried out. In the first method it is assumed that the protection is reached due to fast dump of pressure inside of OFEE case when special membranes are opened. In the second protection method it is offered to establish porous coverings on internal surfaces of OFEE cases. Experiments were carried out on OFEE model with the characteristic size of 1 m at action energy up to 1.5 MJ. It was shown, that these systems cannot protect the transformer body from significant damages. The dynamic protection system of transformer (DPS) has been described. The efficiency of this new system using ASPP has been verified in experiments with autotransformer of 25 MW. It was shown that DPS protects the transformer from considerable damages at least at dynamic impulse of about 3 MJ.

Published: July 2022

This paper presents in detail numerical methods and techniques for lightning impulse (LI) modeling and simulation of power and distribution transformers. The modeling methods are based on equivalent circuits of transformer winding entities resulting from the initial winding discretization determined by the required accuracy. The parameters of the equivalent circuit such as resistances and self- and mutual capacitances and inductances are obtained from field simulations (FEM). The circuit equations of the transformer’s equivalent circuit written in the state space form yield a large system of differential equations that is solved in time-domain by using the standard Runge-Kutta numerical integration technique. The obtained solution represents the voltage distribution over the winding in each moment of the LI-time (50μs). The results verification by comparison against measurements is presented in detail.
Barriers to pneumococcal conjugate 13 vaccination recommendations among physicians in Lagos
Authors: Ojo Oluwafemi
Published: July 2022

Objective: Vaccination rates among risk groups vary between different countries. There are gaps in the implementation of the acceptable recommended guidelines on adult pneumococcal immunization in Nigeria. This study aims to evaluate the barriers for physicians in recommending pneumococcal vaccines.
Methods: This was a descriptive cross-sectional survey involving 97 physicians. Self-administered questionnaires were sent electronically to the physicians to understand the barriers to adult pneumococcal vaccine recommendations among adult physicians in Lagos. The sample size was based on estimation using the Cochrane formula.
Results: Ninety-seven (97) physicians completed the questionnaire with a male to female ratio of 1:1.3. The mean age of the responders was 39.54±6.2 years. About 73(81.1%) of physicians recommended the pneumococcal vaccine and most physicians recommended the vaccine for patients with chronic lung diseases.  The common barriers for vaccine recommendation include: unavailability (53; 54.6%), poor reminder systems (43; 44.3%), inadequate insurance coverage (33; 34%), and Vaccine shortage (31; 32%).
Conclusions: This study suggests that the majority of physicians recommend pneumococcal conjugate vaccines. The major barriers to vaccination include poor access, availability, and cost. There is a need to increase access, cost, and availability of pneumococcal vaccine if the narrative must change.

Published: July 2022

The USNO Bright Star Catalog (UBSC) is a new astrometric catalog of the 1423 brightest stars covering the entire sky, which is published online. It is nearly complete to V = 3 mag except for three stellar systems. A combined astrometric solution of the Hipparcos Intermediate Astrometry Data and two dedicated ground-based campaigns in 2013–2020 is the basis for this catalog. The astrometric parameters for each star include position coordinates, parallax, and proper motion components, and their covariances on the Hipparcos mean epoch 1991.25. 64% of the catalog are flagged as known or suspected double or binary stars. UBSC lists 68 stars missing in Gaia EDR3 and another 114 stars without Gaia parallaxes or proper motions. The formal precision achieved for proper motions is comparable to that of Gaia.
SPORK That Spectrum: Increasing Detection Significances from High-resolution Exoplanet Spectroscopy with Novel Smoothing Algorithms
Authors: Rasmussen Kaitlin C. , Brogi Matteo , Rahman Fahin , Beltz Hayley , Currie Miles , Rauscher Emily , Ji Alexander P.
Published: July 2022

Spectroscopic studies of planets outside of our own solar system provide some of the most crucial information about their formation, evolution, and atmospheric properties. In ground-based spectroscopy, the process of extracting the planets signal from the stellar and telluric signal has proven to be the most difficult barrier to accurate atmospheric information. However, with novel normalization and smoothing methods, this barrier can be minimized and the detection significance dramatically increased over existing methods. In this paper, we take two examples of CRIRES emission spectroscopy taken of HD 209458 b and HD 179949 b, and apply SPORK (SPectral cOntinuum Refinement for telluriKs) and iterative smoothing to boost the detection significance from 5.78 to 9.71σ, and from 4.38σ to 6.89σ, respectively. These methods, which largely address systematic quirks introduced by imperfect detectors or reduction pipelines, can be employed in a wide variety of scenarios, from archival data sets to simulations of future spectrographs.

Changing-look active galactic nuclei (AGNs) present an important laboratory to understand the origin and physical properties of the broad-line region (BLR). We investigate follow-up optical spectroscopy spanning ∼500 days after the outburst of the changing-look AGN 1ES 1927+654. The emission lines displayed dramatic, systematic variations in intensity, velocity width, velocity shift, and symmetry. Analysis of optical spectra and multiband images indicates that the host galaxy contains a pseudobulge and a total stellar mass of

. Enhanced continuum radiation from the outburst produced an accretion disk wind, which condensed into BLR clouds in the region above and below the temporary eccentric disk. Broad Balmer lines emerged ∼100 days after the outburst, together with an unexpected, additional component of narrow-line emission. The newly formed BLR clouds then traveled along a similar eccentric orbit (e ≈ 0.6). The Balmer decrement of the BLR increased by a factor of ∼4–5 as a result of secular changes in cloud density. The drop in density at late times allowed the production of He i and He ii emission. The mass of the black hole cannot be derived from the broad emission lines because the BLR is not virialized. Instead, we use the stellar properties of the host galaxy to estimate

AstroSat View of the Newly Discovered X-Ray Transient MAXI J1803–298 in the Hard-intermediate State
Authors: Chand Swadesh , Dewangan G. C. , Thakur Parijat , Tripathi Prakash , Agrawal V. K.
Published: July 2022

We perform comprehensive temporal and spectral analysis of the newly discovered X-ray transient MAXI J1803–298 using an AstroSat target of opportunity observation on 2021 May 11 during its outburst. The source was found to be in the hard-intermediate state. We detect type C quasi-periodic oscillations (QPOs) at the frequencies of ∼5.4 and ∼6.3 Hz along with a subharmonic at ∼2.8 Hz in the 3–15 keV band. The frequency and fractional rms amplitude of the QPO in the 15–30 keV band are found to be higher than those in the 3–15 keV band. We find soft lags of ∼3.8 and ∼6.8 ms for the respective QPOs at ∼5.4 and ∼6.3 Hz, whereas a soft lag of ∼4.7 ms is found at the subharmonic frequency. The increase in the soft lags at the QPO frequencies with energy is also observed in other black hole transients and attributed to the inclination dependence of the lags. The rms energy spectra indicate the power-law component to be more variable than the disk and reflection components. We find a broad iron line with an equivalent width of ∼0.17–0.19 keV and a reflection hump above ∼12 keV in the energy spectrum. Based on the X-ray spectroscopy and considering the distance to the source as 8 kpc, the estimated mass (∼8.5–16 M
⊙) and spin (a ≳ 0.7) of the black hole suggest that the source is likely to be a stellar mass Kerr black hole X-ray binary.
Tidal Heating at Europa Using the Multifrequency Analysis of Tidal Heating Toolkit
Authors: Walker Matthew E. , Rose Rhoden Alyssa
Published: July 2022

We evaluate the thermal response of Europa’s ice shell to the gravity perturbation of Jupiter using a comprehensive toolkit (dubbed Multifrequency Analysis of Tidal Heating, MATH) that evaluates tidal heating and heat flow in planetary bodies. The tidal heating source is radially resolved and can capture the temperature-dependent pattern of heat production with depth. We use MATH to examine the steady-state thermal profiles through a conductive Europan ice shell, considering the tidal effects of long-term eccentricity variations, obliquity, libration, and nonsynchronous rotation (NSR). In each case, we vary the shell thickness, calculate the combination of tidal heating generated within the shell and heat flux into the shell base that would maintain that thickness, and track the resulting surface heat flux. We find that Europa’s ice shell should be, on average, no more than 12–17 km thick, due to long-term eccentricity variations, and could be even thinner if the basal heat flux is nonnegligible. These results are more consistent with inferences from Europa’s surface geology than previous tidal heating studies that used simplified interior models, a globally averaged tidal heating rate, and/or constant eccentricity. We also find that, for a given stable shell thickness, the surface heat flow remains fairly consistent even as other parameters are varied, perhaps providing an additional method for constraining ice shell thicknesses on ocean-bearing moons. Although Europa’s tidal heat budget and shell thickness seem relatively insensitive to constant obliquity, libration, and NSR, moons in closer-in orbits may be more sensitive to these other effects and should be further explored.

BACKGROUND: Human immunodeficiency virus (HIV) is a big threat to Indonesia and the rest of the world. People with HIV are more prone to opportunistic diseases like tuberculosis (TB) because HIV damages the immune system. AIM: This study aims to determine the prevalence and risk factors (age and gender) that contribute to pulmonary TB among HIV/AIDS patients admitted to Genteng Hospital Banyuwangi. METHODS: This research uses the Observational Analytical, Cross-Sectional method. We collected data from 372 new diagnosed HIV patients between 2019 and 2021. HIV diagnosis was obtained with a rapid test method. At the same time, a pulmonary TB diagnosis was obtained with Xpert MTB/RIF. RESULTS: We found that 372 individuals were HIV positive, and 63 patients among them were also positive for TB (16.93%). The majority of individuals were male (53.22%), in the age group of adults (26–45 years old) (62.1%). While HIV-TB patients were found among those in adult age group (16.13%), all patients positive with HIV-TB still susceptible to rifampicin treatment. The prevalence of TB among HIV patients did not differ significantly by gender or age. CONCLUSION: We found TB co-infection in newly diagnosed HIV patients. Individuals at risk of HIV infection should be screened early to minimize co-infection with other diseases that can aggravate their condition. As a result, the severity and death rate of HIV patients can be reduced in the long run.

Traduction des modèles et prescriptions internationales d’enseignement supérieur et de recherche : analyse comparée des communautés belges
Authors: Fallon Catherine
Published: July 2022

La Belgique est, depuis les dernières décennies, engagée dans un double processus de transformation constitutionnelle, associant fédéralisation et européanisation. Depuis que les régions et communautés ont hérité des compétences en matière d’enseignement supérieur et de recherche (ESR), les deux principales régions, Flandre et Wallonie, affichent des trajectoires spécifiques et présentent aujourd’hui deux régimes différents. Cet article entend retracer les évolutions de ces deux territoires, dessinant, à partir du modèle historique belge, des projets collectifs spécifiques tout en les inscrivant dans des courants sectoriels plus larges, voire mondialisés : les acteurs participent à des réseaux variés qu’ils contribuent à créer, associant universitaires et industriels aux projets des responsables politiques. L’approche socio-historique aborde les transformations des instruments d’action publique (Lascoumes, 2007) : cette décomposition de l’analyse permet de suivre et comparer des mécanismes d’ajustement complexes, propres à chaque territoire, mettant en évidence la différence de la mobilisation des acteurs, la stabilité et la plasticité des institutions face à l’accélération de l’internationalisation et la mise en place de nouveaux projets politiques régionaux.
A geometria aplicada à Évora romana: da malha urbana às termas
Authors: De Morais Sarmento Ricardo
Published: July 2022

Las termas romanas de la ciudad de Évora, descubiertas en 1987 e integradas en el edificio actual de los Paços do Concelho, resultaron ser uno de los ejemplos más importantes de esta tipología a nivel nacional. Esta estructura estaba ubicada cerca del Foro y se afirmó como uno de los edificios públicos más importantes de la ciudad. Con la intervención arqueológica de 2019, se lograron registrar y estudiar nuevas estructuras en el complejo. Varias investigaciones sugieren que la arquitectura de este periodo utiliza un vasto conjunto de reglas geométricas y espaciales para hacer que el espacio sea armonioso y sensorialmente agradable para la experiencia humana. En este sentido, el presente estudio se propone analizar este conjunto termal, utilizando la geometría para tratar de comprender mejor su organización espacial y volumétrica y también la forma en que dicho conjunto se relacionaba con el contexto urbano de la época.[pt] As termas romanas da cidade de Évora, descobertas em 1987 e integradas no actual edifício dos Paços do Concelho, revelaram-se um dos mais importantes exemplares desta tipologia a nível nacional.

On the application of the forming limit diagrams for quality control of blanks for wheelbarrow of ASTM A1008 carbon steel
Authors: Cruz-González Celso , Vargas-Arista Benjamín , León-Méndez Iván , Guzmán-Flores Isidro
Published: July 2022

The effectivity of the forming limit diagrams in manufacturing wheelbarrow by deep-drawing is shown because of the high material scrap rate which reduces productivity. Several chemical, mechanical testing and microstructural analysis were performed to examine sheet quality and their impact on these diagrams. Chemical analysis revealed that Steel 1 and Steel 3 sheets fulfilled the specification without assuring adequate forming process. However, the higher titanium content of Steel 2 improved its formability since it promoted the formation of fine precipitates, thus refining the grain size. This steel had the highest ASTM grain size number G (9.11), which is the lowest average grain size (13 µm) compared to the other steels, which had G values in the range 8.7 to 9.11. Moreover, Steel 2 sheets had the greatest plastic strain ratio (rm = 1.80), the highest strain-hardening exponent (n = 0.250), the lowest anisotropy ∆r = 0.31), yielding better results in deep-drawing strain distribution, the highest forming limit strain (28%) and the highest uniform elongation zone, favoring that failure sites did not occur.
“All the wealth of the world will be in your hands”
Authors: Couto Dejanirah
Published: July 2022

Intended to provide accurate knowledge of the Red Sea at the dawn of the 16th century, the Letters of Afonso de Albuquerque (1452‑1515), appointed first governor of the “Estado da Índia” (1509‑1515) do not deal exclusively with the commercial and geopolitical dynamics of the region. In spite of the significance of these issues, they also contain valuable geographical descriptions of the insular world and the shores of the Red Sea (“Mar Roxo”), explored in 1513 by Albuquerque in his attempt to conquer Aden. This article examines the most significant information about this area – coastal morphologies, ports, anchorages –, navigation practices and political geography, reported in the wake of the 1513 campaign, which, as it should be recalled, intended to gather strategic information to block the entrance of the Red Sea, which was largely dominated by the Mamluk sultanate, the fierce enemy of the Portuguese, at the beginning of the 16th century.
The integration of the island of Ikaros into “international” and regional networks

Published: July 2022

Our recent research on the settlement of Ikaros in the Arab/Persian Gulf brings a new contribution to the knowledge of the networks to which the island belonged from the Hellenistic period to the Parthian period: Seleucid, regional or “international”. In particular, the study of the fortifications, which confirms the foundation of the fortress by the Seleucids, highlighted the existence of phases of abandonment which show that the island should then be excluded from the Seleucid kingdom. At the same time, the perennial breeding and consumption of pigs, a practice that we believe to have been introduced on the island by the Seleucids, did not stop even during the phases of absence of this political power. The pottery clearly indicates a coexistence of practices linked to both “Greek” and regional influences.
Promouvoir les applications mobiles de sport et d’activité physique : des promesses d’empowerment teintées d’enjeux stratégiques
Authors: SOULÉ Bastien
Published: July 2022

Le nombre de personnes ayant recours à des objets connectés ou applications mobiles dans le cadre de leur activité physique va croissant. Cet article analyse la manière dont ces trackers et applications sont présentés par leurs producteurs, avec une focalisation sur deux pionnières (Fitbit et Strava). Leurs modèles de revenus exercent une influence majeure : il faut optimiser la vente de wearables, le téléchargement des applications et le recueil de données d’activité, tout en donnant l’impression que l’utilisateur est le principal bénéficiaire. Le storytelling à l’œuvre conduit donc à survaloriser les promesses de ces dispositifs, tout en occultant la compréhension de modèles d’affaires qui dépendent pour partie de l’exploitation secondaire des données. Les promesses en question sont façonnées pour cadrer avec les intérêts stratégiques des éditeurs d’applications.

Authors: Yaegashi João Gabriel , Otero Cleber Sanfelici , Yaegashi Solange Franci Raimundo , Huete Juan Carlos Sánchez , Nader Michele
Published: July 2022

O cyberbullying tem despertado a atenção de pesquisadores de diferentes áreas, havendo uma preocupação em compreender porque esse fenômeno tem aumentado entre os adolescentes. Por meio de uma revisão integrativa da literatura buscou-se conhecer como o cyberbullying é compreen­dido e conceituado pela comunidade científica, e especialmente, quais os seus impactos na vida dos adolescentes. Foram utilizadas três bases de dados: Periódicos Eletrônicos de Psicologia (PePsic), Scientific Electronic Library Online (Scielo) e Periódicos da Capes. O recorte temporal abrange o período de 2011 a 2020. Foram encontrados inicialmente 32 artigos. Aplicados os critérios de inclusão e de exclusão, restaram 9 estudos que foram analisados. Os resultados revelam que as vivências de cyberbullying podem causar impactos de ordem emocional e comportamental na vida dos jovens, contribuindo para o surgimento de sintomas como ansiedade, tristeza, medo, depressão, baixa autoestima, isolamento social, agressividade contra outros ou contra si, dificuldades de aprendizagem, evasão escolar, doenças psicossomáticos, uso de substâncias psicoativas, ideação suicida, suicídio e homicídio. Chegou-se à conclusão que é necessário a realização de pesquisas sobre prevenção e intervenção em relação ao cyberbullying, envolvendo a família, a escola e também os responsáveis pela elaboração e execução de políticas públicas.
On the minor problem and branching coefficients
Authors: Zuber Jean-Bernard
Published: July 2022

The minor problem, namely the study of the spectrum of a principal submatrix of a Hermitian matrix taken at random on its orbit under conjugation, is revisited, with emphasis on the use of orbital integrals and on the connection with branching coefficients in the decomposition of an irreducible representation of

\operatorname{U}(n)

, resp.

\operatorname{SU}(n)

, into irreps of

\operatorname{U}(n-1)

, resp.

\operatorname{SU}(n-1)

. As is well known, the branching coefficients are trivial (equal to

0

or

1

) for the branchings of

\operatorname{U}(n) \supset \operatorname{U}(n-1)

, while they are not for

\operatorname{SU}(n) \supset \operatorname{SU}(n-1)

, where multiplicities may appear. In the latter case, the problem is shown to be related to the distribution of
spacings
in the minor problem. An explicit expression is obtained for the multiplicities, in terms of an integral stemming from the minor problem, and an Ansatz is given for a closed form expression for arbitrary

n

.
