Published: July 2023

The number of described species of Brachycephalus has rapidly increased in the last decade (n = 22, which represents 56% of the total). Species of the genus Brachycephalus are mostly distributed in isolated mountaintops from Bahia (northeastern Brazil) to Santa Catarina states (southern Brazil), each one occupying only one or a few adjacent mountaintops. Herein, we described a new species of Brachycephalus of the B. pernix group, from Serra do Tabuleiro in Santa Catarina state, which also represents the southernmost known species. The new species can be distinguished from its congeners by a combination of characters, including the following: (1) “bufoniform” body; (2) small adult SVL: 9.57–11.10 mm for males and 10.88–12.70 mm for females; (3) head proportionally small (HL/SVL 19–28%) and eye proportionally large (ED/HL 36–56%); (4) dorsum texture rough; (5) snout shape rounded in dorsal and lateral views; (6) general dorsal body color olive green with head, arms and legs yellow-orangish scattered with olive green, and an orangish vertebral stripe spotted with white and brown colors; (7) skull and skeleton without hyperossification; (8) frontoparietal and sphenethmoid not fused; (9) advertisement with one or two high-frequency notes (6,115–6,562 Hz), and 2–4 pulses per note. The type locality is adjacent to Parque Estadual da Serra do Tabuleiro, a protected area, but we observed various agricultural activities in this locality, including the presence of exotic plants, which can change the amount and the quality of leaf litter, somehow compromising the population of the new species. Another aggravating factor is that the municipality of São Bonifácio has conflicts over land use with irregular occupation and unfinished expropriation processes in Parque Estadual da Serra do Tabuleiro. Considering that Brachycephalussp. nov. is probably a mountaintop microendemic species, it is paramount that future studies quantifying the new species’ full distribution and evaluating population trends to accurately assess its conservation status.

The effects of climate and soil properties on the magnitude of the visual soil quality indicators: a logistic regression approach
Authors: Teixeira Fernando
Published: July 2023

Understanding how different climates and soil properties affect the soil processes requires quantifying these effects. Visual soil quality indicators have been proposed to assess the robustness of the soil processes and infer their ability to function. The scores of the visual soil quality indicators covary with climate features and soil properties, and their magnitude is different in acid-to-neutral and alkaline soils. These variables show collinearities and interactions, and the assessment of the individual effect of each variable on the scores of the visual indicators and the selection of the best set of explanatory variables can only be made with a definite set of variables. Logistic regression was used to calculate the effects of six climate variables and four soil properties, and their interactions, on the scores of eight visual soil quality indicators. Simple models featuring climate and soil variables explained a substantial part of the variation of the visual indicators. Models were fitted for each visual indicator for acid-to-neutral and alkaline soils. The sample size needed was calculated, and the method and its validity were discussed. For two possible outcomes, the sample size using the events per variable (EPV) criterium ranges between 62 and 183 observations, while using one variable and a variance inflation factor, it ranges between 22 and 234. Except for the model of soil structure and consistency for acid-to-neutral soils, with a C statistic of 0.67, all others had acceptable to excellent discrimination. The models built are adequate, for example, for the large-scale spatial outline of the soil health indices, to couple with soil morphological-dependent pedotransfer functions, and so on. Future models should consider (test) other explanatory variables: other climate variables and indices, other soil properties and soil management practices.
On the variational principle and applications for a class of damped vibration systems with a small forcing term
Authors: Wang Shaomin , Yang Cunji , Cha Guozhi
Published: July 2023

This paper is dedicated to studying the existence of periodic solutions to a new class of forced damped vibration systems by the variational method. The advantage of this kind of system is that the coefficient of its second order term is a symmetric $N \times N$ matrix valued function rather than the identity matrix previously studied. The variational principle of this problem is obtained by using two methods: the direct method of the calculus of variations and the semi-inverse method. New existence conditions of periodic solutions are created through several auxiliary functions so that two existence theorems of periodic solutions of the forced damped vibration systems are obtained by using the least action principle and the saddle point theorem in the critical point theory. Our results improve and extend many previously known results.
Major 3 Satisfiability logic in Discrete Hopfield Neural Network integrated with multi-objective Election Algorithm
Authors: Roslan Muhammad Aqmar Fiqhi , Zamri Nur Ezlin , Mansor Mohd. Asyraf , Kasihmuddin Mohd Shareduwan Mohd
Published: July 2023

Discrete Hopfield Neural Network is widely used in solving various optimization problems and logic mining. Boolean algebras are used to govern the Discrete Hopfield Neural Network to produce final neuron states that possess a global minimum energy solution. Non-systematic satisfiability logic is popular due to the flexibility that it provides to the logical structure compared to systematic satisfiability. Hence, this study proposed a non-systematic majority logic named Major 3 Satisfiability logic that will be embedded in the Discrete Hopfield Neural Network. The model will be integrated with an evolutionary algorithm which is the multi-objective Election Algorithm in the training phase to increase the optimality of the learning process of the model. Higher content addressable memory is proposed rather than one to extend the measure of this work capability. The model will be compared with different order logical combinations $ k = \mathrm{3, 2} $, $ k = \mathrm{3, 2}, 1 $ and $ k = \mathrm{3, 1} $. The performance of those logical combinations will be measured by Mean Absolute Error, Global Minimum Energy, Total Neuron Variation, Jaccard Similarity Index and Gower and Legendre Similarity Index. The results show that $ k = \mathrm{3, 2} $ has the best overall performance due to its advantage of having the highest chances for the clauses to be satisfied and the absence of the first-order logic. Since it is also a non-systematic logical structure, it gains the highest diversity value during the learning phase.
Dynamic selection of clarification channels in rumor propagation containment
Authors: Wang Yi , Zhong Shicheng , Wang Guo
Published: July 2023

Rumors refer to spontaneously formed false stories. As rumors have shown severe threats to human society, it is significant to curb rumor propagation. Rumor clarification is an effective countermeasure on controlling rumor propagation. In this process, anti-rumor messages can be published through multiple media channels, including but not limited to online social platforms, TV programs and offline face-to-face campaigns. As the efficiency and cost of releasing anti-rumor information can vary from media channel to media channel, provided that the total budget is limited and fixed, it is valuable to investigate how to periodically select a combination of media channels to publish anti-rumor information so as to maximize the efficiency (i.e., make as many individuals as possible know the anti-rumor information) with the lowest cost. We refer to this issue as the dynamic channel selection (DCS) problem and any solution as a DCS strategy. To address the DCS problem, our contributions are as follows. First, we propose a rumor propagation model to characterize the influences of DCS strategies on curbing rumors. On this basis, we establish a trade-off model to evaluate DCS strategies and reduce the DCS problem to a mathematical optimization model called the DCS model. Second, based on the genetic algorithm framework, we develop a numerical method called the DCS algorithm to solve the DCS model. Third, we perform a series of numerical experiments to verify the performance of the DCS algorithm. Results show that the DCS algorithm can efficiently yield a satisfactory DCS strategy.

Lysippean models on two roman reliefs from Poetovio
Authors: Šmid Katarina
Published: July 2023

This contribution discusses two relief depictions, which follow the works of the Greek master Lysippus. One of the partially preserved reliefs, depicting a youth in motion, characterised by the lock of hair on the front has been in the hitherto literature differently interpreted; Josip Korošec explained it as Kairos. The depictions of that deity share the lock of hair above the front, nakedness, posture, and scales, attached to the cords of the scales, which could also be held by the Poetovian youth. Regarding the other stone relief, the direction of the movement is quite unusual and can be taken after gem depictions, which could (also due to some alterations in arm posture and lower quality) serve as the direct source.

In the lateral side of the ara (either votive or funerary) Hercules, who follows the type of Weary Hercules, ascribed to Lysippus is depicted. The latter is (in contrast to the rarely imitated Kairos) one of the most widespread types in the Imperial era. The depictions of opera nobilia in Poetovian relief sculpture doubtless attest to the fact that the cultivated inhabitants were aware of and commissioned representations of the well-known works of Greek statuary.

Najzgodnejše zanesljivo potrjene sledi poselitve najdemo na hribu Gobavica. Poseljen je bil verjetno že v pozni bronasti dobi, zanesljivo pa v starejšem halštatskem obdobju (Ha C), ko je bil utrjen s kamnitim obzidjem. Njegovi prebivalci so dočakali prihod Rimljanov.

No processo de concepção e introdução das tecnologias de precisão em meio agrícola, há uma desproporção entre os aspectos de produtividade esperada e a atenção prestada aos seus usos e aos seus efeitos na saúde dos agricultores. É esta dinâmica que a ergonomia tenta restabelecer através da análise da atividade de trabalho. Neste artigo, questionamos, através da ergonomía, a agricultura de precisão, os recursos que esta oferece aos agricultores, bem como as limitações que provoca no trabalho real. Por fim, propomos recorrer à análise da atividade a diferentes níveis para acompanhar os agricultores nas escolhas que têm de fazer e pensar de forma diferente a conceção e desenvolvimento destas novas tecnologias.
Estudo sociológico do dispositivo de inaptidão para o trabalho na função pública francesa : o caso da Câmara Municipal de Paris
Authors: Gaboriau Marion
Published: July 2023

Este artigo apresenta uma investigação de doutoramento em sociologia sobre o reconhecimento da inaptidão para o trabalho por motivos de saúde na função pública territorial francesa. Toma como caso de estudo a Câmara Municipal de Paris, que identifica todos os anos a inaptidão para o trabalho de mais de 500 trabalhadores/as e encaminha-os/as para a reclassificação profissional ou para a reforma por invalidez. O trabalho baseia-se num estudo etnográfico de três anos que combina a observação de situações de trabalho e de perícia, entrevistas com diversos profissionais e trabalhadores/as reconhecidos/as como inaptos/as para as suas funções, a análise qualitativa de processos médico-administrativos e o tratamento estatístico de bases de dados. A análise visa compreender as lógicas institucionais (jurídicas, económicas e de gestão) que sustentam o dispositivo de inaptidão, bem como o que alimenta as decisões de inaptidão numa determinada situação. Em particular, a tese explora diferentes cenários de perícia, caracterizados por relações assimétricas de poder entre médicos/as e trabalhadores/as e por um tratamento da informação que é fonte de mal-entendidos e incerteza. De igual modo, lança luz sobre o efeito de (re)produção de desigualdades sociais e de género no reconhecimento e tratamento dos problemas de saúde no trabalho, cujas causas potencialmente profissionais são muitas vezes ignoradas.
Sense of Self-Efficacy in Digital Skills During Teacher Training
Authors: Moor Marcelle , Boéchat-Heer Stéphanie
Published: July 2023

This chapter presents the results of a study of teacher education students' sense of self-efficacy in digital skills based on two almost identical questionnaires distributed before and after lockdown imposed due to the COVID-19 pandemic. Results obtained in 2019 are compared with those of 2021-22 in order to understand how students' digital skills, digital technology representations, and digital practices have evolved during their studies at the University of Teacher Education (States of Bern, Jura and Neuchâtel), Switzerland. These results show students to have globally more positive representations of digital use, an unchanged sense of self-efficacy and a real need for digital use modelling in training to facilitate digital use in future classroom practice.

Published: July 2023

The chapter focuses on the digital competence of TVET trainers and technology acceptance in the context of developing countries. Three objectives were addressed; namely, the level of digital competence of TVET trainers, challenges to the development of digital competence in TVET trainers, as well as factors that determine the acceptance of technologies in their teaching practice. Framed by the digital competence for TVET teachers and the technology acceptance model, the chapter objectives were addressed through a robust review of published articles, policy papers, theses, and dissertations among others, based on the focus of the chapter. Findings revealed the inadequacy of digital literacy of TVET trainers as well as unavailability and access to digital infrastructure among others constituted hindrances to the development of digital competence in TVET trainers. The chapter provides conclusions and recommendations.
Paediatric Mandibular Fracture Management - A Seven Year Retrospective Study
Authors: Yehorov Rostyslav , Yakovenko Lyudmila , Primak Irina
Published: July 2023

Introduction:

Mandibular fractures are one of the most frequent and complex types of traumatic injuries of the maxillofacial region in children. Given significant long-term sequelae of inappropriate healing, adequate diagnosis and choice of management, which takes into account the patient’s age and fracture characteristics, are paramount.

Methods:

The data for this study were obtained from the medical records of patients treated in the Department of Surgical Dentistry and Paediatric Maxillofacial Surgery of the Bogomolets National Medical University from 2014 to 2020. Age, gender, fracture pattern and surgical treatment methods performed in these patients were recorded and analysed.

Results:

A total of 302 children with 376 traumatic fractures of the mandible were managed during the study period. The largest number of fractures was found in the condylar processes region, 42%, and in the body of the mandible, 40%. The majority of patients were males and in the 13–17 age group (147 [49%] cases). Tigerstedt’s maxillary-mandibular fixation splint was used in the majority of cases, alone or in the combination with open or internal fixation.

Discussion:

Whilst the most common type of immobilisation in children in our series was Tigerstedt’s maxillary-mandibular fixation splint, its use is limited to the variable bite period. Alternative fixation options are discussed.
Transformation of Odontogenic Cysts to Neoplasms - A Systematic Review
Authors: Sulistyani Lilies Dwi , Iskandar Lilis , Zairinal Vaza Nadia , Arlen Antonius Kevin , Purba Fatmasari , Ariawan Dwi
Published: July 2023

Background:

Odontogenic cysts have the potential to transform into neoplasms. However, the characteristics of those which transformed to neoplastic tissues have not been well described and the exact causes of that phenomenon are not yet clear.

Objectives:

This study aims to describe characteristics of odontogenic cysts that transformed into neoplasms and to look for their potential etiologies.

Data Sources:

English-written studies indexed in PubMed, Science Direct, and Proquest were assessed using keywords verified by Medical Subject Headings: ‘Odontogenic Cyst’ and ‘Neoplastic Cell Transformation’.

Study Eligibility Criteria:

Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines were used as guidance.

Participants:

Following steps in PRISMA guidelines, 19 articles were fully reviewed (three case series and 16 case reports) with 27 subjects of 16 males (59%) and 11 females (41%) from 15 to 86 years old.

Results:

Cystic origins were eight dentigerous cysts, four odontogenic keratocysts, two residual cysts, one radicular cyst, one calcifying odontogenic cyst, one follicular cyst, one glandular odontogenic cyst, and nine unspecified odontogenic cysts that transformed to ameloblastoma (3 cases) and carcinoma (24 cases).

Limitations:

Neoplastic transformations of odontogenic cysts arose from epithelial remnants of inadequate odontogenic cyst removal and chronic inflammation due to infection. However, the exact causes of their transformations remain unclear.

Conclusions:

Therefore, careful removal of odontogenic cysts and regular postoperative follow-ups are key to prevent recurrence and neoplastic transformation. Future studies are needed to investigate potential causes of neoplastic transformation of odontogenic cysts.
Comparative evaluation of circumferential crestal bone loss after 1 year of implant placement with flapless versus flap surgery using surgical template after immediate loading in the posterior mandibular region using cone-beam computed tomography: A randomized controlled trial
Authors: Dandekar Sayali , Lahoti Krishankumar , Gade Jaykumar , Agrawal Megha
Published: July 2023

Aim:

The study was aimed to evaluate circumferential crestal bone level after one year of implant placement with flapless versus flap surgery using surgical template after immediate loading in the posterior mandibular region using CBCT.

Setting and Design:

The study was designed as a Randomized controlled trial.

Material and Methods:

32 implants were placed in single edentulous spaces in the mandibular posterior region after random allocation into two groups: Flap surgery (Group A) and Flapless surgery (Group B). Virtual implant planning was performed using Blue Sky Bio software, and static CBCT guided 3D printed surgical templates were fabricated for all participants of both the groups. Immediate non-functional temporization was performed. Circumferential crestal bone levels were assessed after surgery and one-year follow-up using CBCT and XELIS software. Vertical bone loss (VBL) and horizontal bone loss (HBL) was assessed on four sides: buccal, lingual, mesial and distal.

Statistical Analysis Used:

Data was analyzed using Statistical Package for Social Sciences IBM Corp. Released 2017, IBM SPSS Statistics for Windows, Version 25.0. (Armonk, NY: IBM Corp.) and Graph Pad Prism 7.0 version. The level of significance was chosen <0.05. Chi square test was performed to assess the difference in the age in the two groups. Mann-Whitney U test was performed to compare the two groups for outcome measure. Graphically, quantile-quantile (Q-Q) plot was made using mean and standard deviation for normality verification of data.

Results:

100% survival rate and patient compliance was observed along the one-year follow-up duration. By using Mann-Whitney U test, statistically significant difference was found in the vertical bone loss among participants of Flap surgery (Group A) and Flapless surgery (Group B) on all the four sides after one year of implant placement. However, significant results were not obtained for the difference in the horizontal bone level.

Conclusion:

Within the limitations of this study, vertical bone loss measured circumferentially was more positively correlated with the implants placed with flap surgery compared to flapless surgery after immediate loading in the posterior mandibular region after one year.

Aim:

The aim was to compare the efficacy of various herbal disinfectants on irreversible hydrocolloid impressions and to investigate the effectiveness of three herbal disinfectants and a chemical disinfectant against particular pathogens.

Settings and Design:

In vitro-a comparative study.

Materials and Methods:

The following methodology was followed to achieve the objectives. Four maxillary impressions were made for each selected patient with irreversible hydrocolloid impression material. The predisinfection swabs were taken from impression sites of teeth 17, 13, 27, and 23 (FDI system of tooth numbering). The impressions were immersed in all four different disinfectants such as 2% glutaraldehyde, Aloe vera solution, 50% neem oil, and apple vinegar solution, then the postdisinfection swabs were taken from the same sites 17,13,27,23 and then cultured onto sheep blood agar and examined for growth, and colony forming units (CFUs) ofStreptococcus viridans,Streptococcus mutans,Streptococcus sanguis, andActinomyces viscosus. The comparative analysis was done for the predisinfection and postdisinfection values in each study group.

Statistical Analysis Used:

Descriptive analysis, Kruskal Wallis test, Mann Whitney post hoc test, Wilcoxon signed rank test.

Results:

The results revealed that the mean CFUs ofS. viridans,S. mutans,S. sanguis, andA. viscosusduring postdisinfection samples were statistically significant when compared to predisinfection samples. Multiple comparison of the mean CFUs of all 4 microorganisms in the control group and in 50% Neem oil group was significantly lesser compared toA. veraand Apple Vinegar group.

Conclusion:

CFUs ofS. viridans,S. mutans,S. sanguis, andA. viscosussignificantly decreased in the 50% neem oil group as well as the control group. As a result, 50% Neem oil was a viable option for disinfecting alginate impressions.
Cosmetic Surgery Procedures Accessed by Nigerian Women at a Single Private Cosmetic Surgery Practice: A Retrospective Review
Authors: Michael AI , Oladeji FJ , Abe OO , Ethe E
Published: July 2023

ABSTRACT

Background:

Little is known about the cosmetic surgery procedures sought by Nigerian women.

Aim:

We sought to report the proportion of cosmetic surgery procedures accessed by Nigerian women and determine any associations between the demographics and cosmetic procedures accessed.

Patients and Methods:

A retrospective review was conducted between January 2020 and July 2021 of all cosmetic surgery procedures at a single private cosmetic surgery practice. Data were analyzed using means, Mann–Whitney U-test, chi square test, and Fisher’s exact test as appropriate. The statistical significance was set at P ≤ 0.05.

Results:

Of the 392 consultations for cosmetic procedures, 245 (62.5%) patients accessed cosmetic surgery. Most were women (239 (97.6%)) and single (178 (72.7%)). The median age of the patients at surgery was 29.0 years (IQR 26–33), the median weight was 78.8 kg (IQR 71.4–88.8), and the median body mass index (BMI) was 28.1 (IQR 25.7–32.3). Liposuction was the procedure accessed by nearly all the patients (224 (91.4%)). Next to this was bilateral buttock augmentation (199 (81.2%)). Other cosmetic procedures such as tummy tuck, facial cosmetic surgery, umbilicoplasty, and labiaplasty each constituted less than three percent of the patients. The abdomen (224 (91.4%)), back (219 (89.4%)), and arms (79 (32.2%)) were the most common regions of the body sought for liposuction, while the calves (2 (0.8%)) were the least. Liposuction of the arms was associated with the BMI (p < 0.003).

Conclusion:

Liposuction and bilateral buttock augmentation are the most common cosmetic surgery procedures accessed by this cohort of Nigerian women.
Cytomegalovirus Reactivation in Ulcerative Colitis Patients: Early Indicators
Authors: Altunal LN , Ozel AS , AK C
Published: July 2023

ABSTRACT

Background:

The association of cytomegalovirus (CMV) infection with ulcerative colitis (UC) still remains a controversial topic for the clinicians.

Aim:

In this study, we aimed to elucidate the CMV infection related parameters in the exacerbation of UC.

Material and Methods:

In this study, 812 UC patients who have admitted to our institution between June 2008 and November 2020 were analyzed retrospectively. CMV infection was diagnosed by the detection of CMV DNA with polymerase chain reaction (PCR) in tissue biopsies with presence of clinical colitis symptoms. CMV negative UC patient group was defined as UC activation group with negative PCR results.

Result:

A total of 153 patients met the inclusion criteria during the study period, with a median age of 41.8 years. CMV PCR positivity had been detected in tissue biopsy in 43 (28.1%) UC patients. CMV-positive patients had a statistically significant higher frequency of steroid resistance, treatment with azathioprine, longer disease duration, longer remission, and hospitalization day. The mean C-reactive protein (CRP) level, platelet to lymphocyte ratio (PLR) were higher, and mean albumin level was lower in CMV positive patients, with statistically significance. Also, colectomy and anti-tumor necrosis factor-α (TNF-α) therapy were more frequent in CMV-reactivated group in long-term follow-up. In a multivariable model, steroid resistance, treatment with azathioprine, long disease duration, low albumin value was independently associated with colonic CMV infection.

Conclusion:

Steroid resistance, treatment with azathioprine, long disease duration, low albumin levels were significant risk factors for CMV colitis, among patients with UC activation.
Analgesic Efficacy of Erector Spinae Plane Block in Pediatric Abdominal Surgery: Guidance with Conventional Method and NOL: Case Series
Authors: Ozdemir C , Isik B , Kurtipek O
Published: July 2023

ABSTRACT

Background:

Erector spinae plane (ESP) block is a regional anesthesia technique that blocks both somatic and visceral nerve fibers. Despite its high analgesic potential, its mechanism of action is not yet fully understood. The ultrasound-guided ESP block, which can be easily performed, makes important contributions to the control of intraoperative pain in pediatric patients undergoing abdominal surgery. The follow-up of pain in the intraoperative period is usually done by evaluating the changes in hemodynamic parameters. Due to physiological differences in pediatric patients, it is more difficult to do this with only hemodynamic changes than in adult patients.

Aim:

The NOL® (Nociception Level) monitor calculates the nociception/pain score by evaluating many parameters through a proprietary algorithm. Our primary aim was to demonstrate the effectiveness of ESP block with an advanced pain monitor in this patient group; our secondary aim was to investigate the necessity of pain monitors in the pediatric patient group.

Methods:

In this case series, we applied intraoperative NOL® monitoring in addition to standard monitoring (ECG, SpO2, heart rate, EtCO2) in pediatric patients (16 cases) who were scheduled for abdominal surgery and underwent ESP block.

Results:

Considering the hemodynamic data, NOL values, postoperative pain scores, side effects, and complications, it was concluded that ESP block can be used safely in this patient group. Although the hemodynamic data and the NOL® index were compatible with each other after a nociceptive stimulus, the NOL index was less affected by other variables and gave the clinician clearer information about pain.

In South Africa, as in many other Low- and Medium-Income Countries (LMICs), there is a high prevalence of mental disorders. Despite the high burden of mental illness in these countries, only a few professionals are available to provide mental healthcare. As a result, many people experiencing mental health problems are propelled to consult with their religious/spiritual healers. Amongst many religious/spiritual healers who are consulted for help regarding mental health challenges are Pentecostal pastors. Pentecostals comprise of a heterogeneous group of Christians with varied backgrounds, races, ethnicities, socioeconomic status, and educational levels. This group of Christians display an interesting difference from the public and also in most of their Christian studies. However, not much is known about the notions Black Pentecostal pastors’ have of mental illness specifically regarding what it is and how it is understood or described especially when viewed from within a South African context. This study consequently explored the perceptions of mental illness as they are held by Black Pentecostal pastors in Polokwane, South Africa. Nineteen Black Pentecostal Pentecostal pastors residing in Polokwane were interviewed using semi-structured interviews. Data were analysed using Thematic Analysis (TA). The study found that the Black pastors hold differing views of mental illness which one can refer to as a Bio-Psycho-Social-Spiritual view of mental illness. The pastors’ notions of mental illness were mainly dominated by spiritual causes although they acknowledged other sources. The study also found that the pastors’ notions of mental illness were limited to psychosis or psychotic disorders, which they referred to as “bogaswi” in Sepedi language. Mental illnesses without psychotic features were less known to Black Pentecostal pastors. Furthermore, the pastors’ notions of mental illness were influenced by their theological (Pentecostal) and cultural upbringing (Black Africans). The study has several implications for future research, and additionally for clinical psychology practice and training. Findings of this study are discussed broadly within the Bio-Psycho-Social-Spiritual model of mental illness.
“Dealing With it.” Creating External Fit in HRM Through Learning and Collaborating
Authors: Koster Ferry
Published: July 2023

Aim – The aim of the article was to begin with it explicitly adopts a best fit approach to external fit in HRM, by examining HRM innovation as the de-pendent variable. Then the article theorizes how HRM innovation relates to external developments that organizations experience. And finally, a theoret-ical framework is developed to understand how organizations to adapt to these developments. Methodology - The present study relies on a quantitative method and a deductive approach. Cross-sectional data were collected including several cases at one point in time. The responses from these cases provide the information for testing the hypotheses that state relationships among spe-cific variables. To investigate whether it was possible to reduce information and to create reliable measure of multiple items, a scale analyses were per-formed. Findings - The main findings of this study are twofold. First, the more de-velopments organizations face, the more innovate they are with regard to how they manage their human resources. Secondly, these innovations take place because organizations have organizational learning practices and co-operate more often on HR related issues with other organizations. Practical implications - Findings are basically in line with alignment ap-proaches, while adding more detail to the underlying mechanisms through which alignment is achieved according to the dynamic capabilities approach and the relational view. According to these approaches, organizations seek internal and external fit and those possessing dynamic capabilities and ex-ternal ties are better in achieving such fit. Since facing several trends means that misfits occur between the environment and the organization, organiza-tions respond by innovating their HRM through learning and collaborating. Originality/Value - This study tests the hypotheses that organizations achieve external fit via (1) the development of organizational learning prac-tices; and (2) by collaboration with other organizations. Quantitative data gathered with a survey among 711 private organizations from the Nether-lands are used to test these hypotheses.
Development of CSR and Diversity Trends in Companies: Review
Authors: Šefránek Radoslav , Mikle Lenka
Published: July 2023

Aim – The aim of the article was to summarize and analyze published scien-tific findings from 2005 to the present in the context of CSR and diversity trends, which are viewable in selected scientific databases. Publications available in the scientific databases WOS and Research Gate were used. Methodology - The method used for the research is a systematic review. Attention was paid primarily to the examination of the content and perspec-tive on the issue at hand. Analyzing changes in CSR and diversity trends in the workplace not only provides a comprehensive view of the current state of play that can help improve CSR and assist managers with diversity man-agement, but also predicts changes that may occur in these industries in the future. For this reason, the following research questions were con-structed: What changes have occurred in CSR over time? What changes have occurred in diversity trends in the work environment over time? Findings -The results section contains, among other things, a summary of the authors’ methodologies and results. The results of this work show the speed of evolution of these topics and from the given findings, predictions can be made about the future development of CSR or diversity in the work environment. The biggest factor that has stirred those waters within cor-porate diversity has been globalization, this has caused many migrant work-ers of different races and religions. If a company knows how to work with these changes, it can use diversity to its advantage, but in some places, diversity can have a rather negative effect, especially diversity of languages in the workplace. As already mentioned, diversity and CSR trends are con-stantly changing and evolving. Limitations of the study The limitation of this study is mainly dealing with the available publications on the mentioned scientific databases. Most of the studies reviewed focused with the situation in Europe and the United States. It is important to note that due to the rapid development and com-prehensiveness of the topic, not all changes in the areas of CSR and diversi-ty trends may have been listed. Practical implications - This research shows in a relatively short period of time a huge lap in the perception of employee diversity in the workplace and in the development of CSR around the world. Originality/Value -The research findings can contribute to an overall as-sessment of the current situation and to possible predictions for the future.

El presente artículo reflexiona sobre el desafío que significa construir un Estado intercultural en el Perú. Así, se defiende la tesis de que la implementación de un Estado intercultural en el Perú, teóricamente posible, es un objetivo difícil de alcanzar, pues nuestro país tiene tras de sí una larga tradición de exclusión de las poblaciones originarias y afroperuanas. Sobre la base de estudios y observaciones de destacados científicos sociales, se concluye que, convertir al Estado peruano en un Estado intercultural, es un futurible.

Published: July 2023

La sostenibilidad es el escenario actual donde convergen diferentes actores:  sociedad civil, empresas y gobiernos articulan esfuerzos para responder a los Objetivos de Desarrollo Sostenible y así ayudar a reducir los principales desafíos globales como la pobreza y los desastres ambientales. La marca como dinamizador social no es ajena a este compromiso. El propósito de este trabajo es identificar las aproximaciones teóricas sobre la marca y la sostenibilidad; para esto se estableció un protocolo de revisión descriptiva de literatura utilizando la ecuación TITLE-ABS-KEY ("sustainability AND branding"). Los documentos fueron obtenidos en el sistema de bases de datos Scopus, EBSCO, JSTOR y ScienceDirect, en un periodo de 2009 a 2022, como resultado se obtuvieron 333 referencias. Se organizaron bajo la metodología DESLIZAR de Maeda (2006), dejando un total de 88 artículos. Los resultados develan un limitado constructo teórico sobre la marca y la sostenibilidad, convirtiéndose en una oportunidad para el aporte conceptual en futuras investigaciones.

Authors: Nempeque Quinchía Alexander
Published: July 2023

El crecimiento gradual y la ubicuidad de las nuevas tecnologías de la información y la comunicación (NTIC) han desencadenado cambios en el comportamiento de los consumidores y la incorporación de elementos digitales a los modelos de negocio. Las plataformas emergentes de realidad virtual, inteligencia artificial y procesamiento avanzado de datos intervienen en la vida cotidiana de diferentes maneras. En este escenario, la antropología aplicada a los negocios se ha enfrentado al reto de remodelar e integrar lógicas de la ciencias de datos para comprender el mundo híbrido de la vida real y su expansión hacia los mundos sintéticos. Con base en la exploración de la industria de las bodas, ahora atravesada por la experiencia de la realidad extendida, este trabajo reflexiona en torno al ejercicio de la antropología en los nuevos escenarios de comportamiento del consumidor y surgimiento de negocios digitales, sus aplicaciones y desafíos en el campo tecnológico.
