Authors: Silva Brenda Fernanda Pereira da , Santos-Vitti Laís , Faro André
Published: April 2021

Abstract This study aimed to present validity evidence based on internal structure of the Kessler Scale of Psychological Distress (K10), to show its relations with the Perceived Stress Scale (PSS-10), and to present a social distribution of distress in the present sample. Participated in the study 717 residents of Aracaju, State of Sergipe, by means of household data collection. A sociodemographic questionnaire, K10, and PSS-10 were used as instruments. Exploratory Factor Analysis was performed using the Factor software, which indicated the scale unidimensionality, explaining 69.9% of the variance. Cronbach’s alpha was 0.93, and the model adjustment indices were satisfactory. A positive and statistically significant association between K10 and PSS-10 was observed. Regarding the social distribution, the levels of distress were higher in women, patients with chronic diseases, users of controlled drugs, and unemployed participants. It was concluded that K10 presented robust psychometric properties for the detection of distress in general population.

Published: April 2021

ABSTRACT: Objective: To describe the socioeconomic, behavioral, clinical, and health-related characteristics of Brazilian older adults with Alzheimer's disease (AD). Methods: Baseline data from the Brazilian Longitudinal Study of Aging were analyzed. This nationwide survey interviewed 9,412 adults aged at least 50 years. Self-reported medical diagnosis of AD and exposure variables (sociodemographic, clinical, behavioral, and health-related) were assessed by face-to-face questionnaire-based interview. Multivariate analyses accounted for possible confounding factors, and values were reported in prevalence ratio (PR) and 95% confidence interval (95%CI). Results: Participants with AD have important demographic differences compared with older non-AD participants such as low education level and retirement. Clinically, these patients reported more medical appointments, falls, and higher frequency and duration of hospitalizations compared with non-AD participants. These characteristics may be related to worse physical and mental health observed in this population. Indeed, two out of five older adults with AD in Brazil reported always feeling lonely, while two out of three said they felt depressed or sad much of the time. Adjusted analyses showed that patients with AD were 95% (95%CI 1.08 – 3.50) more likely to be hospitalized in a year compared with non-AD older adults. People with AD in Brazil were more likely to be diagnosed with diabetes (PR = 1.83 [95%CI 1.08 – 3.12]), depression (PR = 3.07% [95%CI 1.63 – 5.79]), Parkinson's disease (PR = 17.63 [95%CI 6.99 – 44.51]), and stroke (PR = 3.55 [95%CI 1.90 – 6.67]) compared with non-AD participants. Conclusion: Older adults with AD in Brazil reported impaired physical and mental health compared with the non-AD population.

Authors: Abba Maria Julieta , Streck Danilo Romeu
Published: April 2021

Abstract Internationalization is a trend that, in the last two decades, has been firmly established in Latin America. However, this article argues that it is part of a historical process that has been constituted within the region with characteristics of its own. For this reason, this paper aims to identify the contributions of the 1918 Cordoba Reform to the analysis of the university internationalization process in Latin America. A bibliographical and documentary research with a historical content was carried out. Its result points out that the legacy of the reform, with regard to regional integration and the concept of university autonomy, contributes to a view of internationalization rooted in the Latin American context.

Türkiye’deki Kira Sertifikası (Sukuk) İhraçlarının Büyüme Üzerindeki Etkisine Dair Ampirik Bir Analiz: 2010-2019
Authors: ORHAN Zeyneb Hafsa , TIRMAN Nurullah
Published: April 2021

Dünyada İslâmî finans olarak anılan alan, İslâm’ın ilke ve etiğine uygun finansal hizmetler sunulmasına dayanmaktadır. Bu amaçla 1970’lerin sonundan itibaren geliştirilen bu yapı içerisinde bugün için en öne çıkan unsur, Türkiye’de katılım bankacılığı olarak bilinen İslâmî bankalardır. Bunu takiben ise yine Türkiye’de kira sertifikası olarak geçen, yurtdışında ise daha geniş anlamda sukuk olarak bilinen yapı gelmektedir. Kira sertifikası, Türkiye için de önemi giderek artan bir görünüm arz etmektedir. Fakat bu artan önemine rağmen kira sertifikalarının büyüme için ne derece önemli olduğuna dair gerek yabancı gerekse Türkçe literatürde fazla bir çalışma yapılmamıştır. Bunlardan hareketle bu makalenin amacı, İslâmî finans alanının giderek daha fazla öne çıkan bir unsuru olan kira sertifikası (sukuk) ihraçlarının büyüme üzerindeki etkisini 2010-2019 arası dönemde Türkiye için ekonometrik analize tabi tutmaktır. Çeyrek dönemlik veriler için Hazine ve Maliye Bakanlığı (HMB), Türkiye Katılım Bankaları Birliği (TKBB) ve Merkezi Kayıt Kuruluşu’ndan (MKK) faydalanılmıştır. Kira sertifikası ihraçlarının yanı sıra tahvillerin de karşılaştırmalı olarak ekonomik büyüme üzerindeki uzun dönemli ilişkisini incelemek için ARDL sınır testinden yararlanılmıştır. Analizden elde edilen sonuçlara göre hem devlet hem de katılım bankaları tarafından ihraç edilen sukukların büyüme üzerindeki etkisi anlamlı bulunmuştur fakat bunlardan ilkinin etkisi pozitif iken ikincisininki negatiftir. Her iki etki de rakamsal olarak ufak kalmıştır. Sonuçlardan hareketle özellikle devlet tarafından ihraç edilen kira sertifikalarına ağırlık verilmesi önerilebilir.

Published: April 2021

Ekonomik kamu politikası modelleri olarak teknoparkların başarısı bir yandan kamu politikalarıyla sağlanan teşvik, destek ve mevzuata, bir yandan da teknopark yönetimlerinin uyguladıkları faaliyetler ve düzenledikleri programlarla doğrudan ilintilidir. Bugün Türkiye’ de teknoparkların büyüme ve kalkınmadaki etkinliklerini ölçmek kolay olmayabilir çünkü doğrudan ve dolaylı etkiler ile bununla ilintili parametrelerin sayısı çoktur. Bu makalenin amacı Türkiye’deki teknoparkların bu anlamdaki etkinliklerini mevcut teknoloji ve inovasyon politikaları, teknopark şirketlerinin faaliyetleri ve firma potansiyelleri çerçevesinde ortaya koymak ve bunları artırmaya yönelik genel odak noktalarını tartışmaktır. Burada, kamu yönetiminin karmaşık-boyutları olsa da nesnel-değişken olarak en önemli etkenin teknoparktaki şirketlerin kapasite ve potansiyeli olduğu hipotezi vurgulanmaktadır. Çünkü şirketlerin çıktısı teknoparkların sağladığı faydanın çıktısı olarak ekonomi ve kalkınmaya yansıyacaktır.

Crime Scene Investigation Issues: Present Issues and Future Recommendations
Authors: Osman Khairul , Gabriel Gina Francesca , Hamzah Noor Hazfalinda
Published: April 2021

Crime Scene Investigation is the backbone of any criminal investigation. Expert report generated by Crime Scene Investigators are based on scientific evidence and are reported in a standard form. The content, when published should be reviewed rigorously by its peers. The expert report is a document detailing out how the investigation process of a crime scene was performed. The process of collecting and evidence processing do not only entail identifying, collecting and storing evidences for later analysis but it is a step by step process that is well structured in a document called Standard Operating Procedure (SOP) for Crime Scene Investigator. SOP is a complex document and sometimes overwhelmingly technical for the uninitiated. But if understood, it can be a good guide for law practitioners to determine if a piece of evidence should be included in a case. This article details out the SOP which entails groundwork before entering a crime scene, processing of a crime scene and wrapping up of the crime scene investigation. At each step, this paper will look at how it is adopted in current practices, its weakness and suggested improvement that should be adopted to ensure a final quality expert report.
Is Mediation a Process of ‘Law’? A Hart-Ian Perspective
Authors: Jing Zhi Wong
Published: April 2021

Mediation, as a form of dispute resolution, is widely practiced. Nations across the world recognize it as an increasingly appropriate form of dispute resolution. But the existential question remains. Can we rightly ascribe the word ‘law’ to the processes of mediation? This article makes one qualified proposition. Mediation is an extra-legal process, unless it is used to realize the law (and justice). This is for two reasons. First, mediation’s processes and mediated outcomes do not in themselves cause judges’ obeisance and adherence. Mediated settlements must rely on the law of contract for its validity and efficacy. Second, even if mediation is legislated to form part of our law, it is extra-legal. It does not comport with the minimum content of natural law in that it does not guarantee the realization of the law and access to justice. If we are to regard mediation as law, mediation must be used to realize the law and guarantee access to justice.

Autogenous grinding mill process control practices
Authors: Khaymovskiy S. S.
Published: April 2021

This paper considers pre-requisite conditions for developing grinding mill control systems and describes the main problems of control and existing constraints. The author selected a set of grinding equipment that consists of autogenous grinding mills and ball mills. The paper considers the selected mill types as control objects. It is shown that there exists a good correlation between the mill charge and its acoustic and vibration noise. The paper examines the relationship between the level of vibroacoustic noise and the mill motor power draw and defines what can be considered an extreme dependence, as well as the conditions in which a stable operation of the automatic system can be maintained excluding the mill overload mode. The paper specifies what hardware and software means would be necessary to implement such system and describes the mill charge analyzer VAZM-1M developed by Soyuztsvetmetavtomatika that was selected for this application. The author looks at certain downsides typical of the conventional control scheme when the head mill feed rate changes as the mill motor power draw changes without allowing for changing physical and mechanical properties of the ore material. The author also considers the capability of the VAZM-1M analyzer in terms of mill load estimation accuracy. This laid the basis for developing mill protection and optimization algorithms for the AG and Ball Mill comminution circuit. The paper features a block diagram of the control algorithm and its brief description. The algorithm consists of blocks, which are responsible for the following actions: they receive key process parameters from the process control system database, check them for validity, perform initial processing and filtering; after that they analyze the trends of the measured parameters and analyze if an overload condition is probable. As decided by the mill operator, the ore flow rate can be adjusted. The paper describes a case study of running an AG mill control system on the basis of the above described algorithm and using the VAZM-1M analyzer. It is noted that this algorithm can be implemented both as an adviser for the operator and for automatic control of the mill when running in overload mode.

Background. Extramedullary infiltration (EI) is relatively common in children with acute myeloid leukemia (AML) (up to 20-25 %). However, its clinical and prognostic significance remains poorly understood.

Objective: to describe clinical features and to define prognostic significance of EI in children with AML.

Materials and methods. The subjects of retrospective observational study were 228 children with de novo AML. The median age was 6.6 years. All of them were treated according to the protocol AML-MM-2006 from April 2007 to June 2018.

All patients with EI were divided into three cohorts according to the localization of the lesions: 1) central nervous system (CNS) involvement (CNS group), 2) other localizations apart from CNS (myelosarcomas (MS) group), 3) combined lesions (CNS + MS group).

Results. EI was diagnosed in 84 patients (36.84 %) with de novo AML. Among them 47 (55.95 %) had CNS involvement, 20 (23.81 %) had MS, 15 (17.86 %) had both CNS involvement and MS. 5-year overall survival (OS) rate was slightly higher in patients with CNS involvement than in children without EI - 80 ± 12 % vs 71 ± 9 %, p = 0.26, however OS in patients with MS was significantly lower - 45 ± 16 % vs 71 ± 9 %, p <0.001. In addition, OS in high-risk patients according to the protocol AML-MM-2006 who underwent allogenic hematopoietic stem cell transplantation (HSCT) without EI and with MS (± CNS involvement) was similar to OS in main groups - 81 ± 11 % and 42 ± 26 % respectively, p = 0.004. 5-year event-free survival in patients with MS was also lower than in children without EI - 38 ± 16 % vs 51 ± 8 %, p = 0.011.

Conclusion. Patients with MS had worse 5-year OS and EFS than children without EI according to our study. Moreover allogenic HSCT conducted in first clinical remission did not improve the survival rate. Neuroleukemia as the only EI was not an unfavorable prognostic factor in our cohort of AML patients and was more often associated with inv(16).

Published: April 2021

Objective: to determine antimicrobial resistance of Enterococcus faecium and Enterococcus faecalis isolated from blood culture of hematological patients during different study periods.

Materials and methods. Antimicrobial susceptibility of Enterococcus spp., collected as part of the multicenter study was tested by the broth microdilution method (USA Clinical and Laboratory Standards Institute (CLSI), 2018), to daptomycin by Etest (bioMeriéux, France). High-level gentamicin resistance (HLGR) and high-level streptomycin resistance (HLSR) was performed by the agar dilution method (CLSI (Oxoid, UK), 2018).

Results. The susceptibility of 366 E. faecium (157 in 2002-2009 and 209 in 2010-2017) and 86 E. faecalis (44 in 20022009 and 42 in 2010-2017) was studied. In the second study period (2010-2017) the rise of vancomycin-resistant E. faecium (VREF) increased from 8.3 % to 23.4 % (p = 0.0001), and two linezolid-resistant (LREF) were identified. All VREF and LREF remained susceptible to daptomycin and tigecycline. The rate of susceptible to tetracycline E. faecium remained the same (73.9 and 74.6 %), and an increase in susceptibility to chloramphenicol (74.5 and 82.3 %) was observed. Susceptibility of E. faecium to tetracycline was detected with almost the same rate and in a part of isolates, the increase of susceptibility to chloramphenicol was registered during the analyzed periods. The rise of E. faecium susceptible to HLGR and HLSR has increased significantly in 2010-2017 compared to 2002-2009. Erythromycin, levofloxacin, ampicillin and penicillin had the least activity against E. faecium (less than 5 %).

All E. faecalis were susceptible to tigecycline, linezolid, and teicoplanin. Only one of E. faecalis had intermediate resistance to vancomycin. High susceptibility to ampicillin in E. faecalis remained unchanged (97.7 and 97.6 %, respectively). In the second period of the study the rise of susceptible E. faecalis decreased significantly to penicillin (from 97.7 % to 76.2 %), to levofloxacin (from 59.1 % to 31 %), to HLSR (from 52.3 % до 31 %), and to HLGR (from 47.7 % to 26.2 %), remained unchanged to chloramphenicol (52.3 % and 50 %) and was minimal to erythromycin and tetracycline.

Conclusion. The study demonstrated higher rates of antibiotic resistance among E. faecium, which consisted of an increase in VREF and the appearance of linezolid-resistant strains. High susceptibility to ampicillin remained in E. faecalis, but there was an increase in resistance to penicillin and aminoglycosides.

Authors: Mora-Ríos Jazmín , Ortega-Ortega Miriam
Published: April 2021

Introduction. Research about stigma on mental illness in different sociocultural contexts is crucial to guide international efforts to reduce discrimination. Objective. Analyze the psychometric properties of the Perceived Devaluation and Discrimination (PDD) scale adapted for the Mexican population and its relationship with sociodemographic variables and interpersonal contact. Method. The study was based on a psychometric and cross-sectional design. The PDD scale was applied to a sample of 295 participants recruited through community programs in the south of Mexico City. Data were analyzed using confirmatory factor analysis to identify the subscales of PDDs. These subscales were compared by age, gender, and education using a univariate analysis. One-way analysis of variance (ANOVA) was then performed to determine whether there were differences in educational level between three PDDM-subscales. Results. The PDD scale obtained an adequate global internal consistency (α = .78). Three PDDs factors were identified: myths and stereotypes, favorable attitudes, and social exclusion, which explain 57.8% of the total variance. The results shows an Χ2SB = 140.88 (df = 143, p = .05, CFI = 1, RMSEA = .000, CI [.000, .029]). Other findings showed significant differences in favorable attitudes toward mental illness subscale by gender and age. The ANOVA results for the social perception of the devaluation subscale reveal that those with a higher educational level could be more aware about devaluation in society toward people with mental illness than other groups with lower education (F = 4.88, p = .005). Discussion and conclusion. The PDD-M scale adapted in Mexico is a culturally valid and reliable measure that could be useful for evaluating the variations and commonalities of public stigma in comparative studies between Latino populations and other international research contexts.

Published: April 2021

Introdution. Burnout syndrome is a social and health problem in college students. Objective. To synthesize evidence from previous studies on the prevalence of burnout syndrome in university students in their three-dimensional approach. Method. The search strategies followed the PRISMA guidelines and were based on the following descriptive terms: “burnout,” “studies,” “prevalence,” “students.” Pubmed, Web of Science Core Collection, PsicINFO, and Scielo were consulted. An evaluation of the quality of the information was carried out applying the STROBE positioning guidelines. Results. We found 1,406 studies that were reduced to 46 studies for final analysis using the STROBE statement, eventually leaving 20 studies. One study (5%) was conducted in North America, five (25%) in Asia, nine (45%) in Latin America, and five (25%) in Europe. Of the 20 studies evaluated in the systematic review, those that had the best overall evaluation in the STROBE analysis were selected for discussion, corresponding to 10 (out of 75% of STROBE). Overall prevalence of each dimension of the syndrome was estimated at 55.4% for emotional exhaustion, 31.6% for cynicism, and 30.9% for academic efficacy. Discussion and conclusion. Moderate levels of burnout syndrome prevail in the different populations of university students of different careers worldwide. In only a few studies is the prevalence low and this could be due to multiple evaluative variables.
A NEW-FANGLED CONTROLLING STRUCTURE FOR MITIGATING VOLTAGE SAG USING THE DVR
Authors: Et. al. B. Durai Babu,
Published: April 2021

Voltage mitigation in electrical power circulation systems is unique of the crucial errands in recent days, which affects the overall presentation of the distribution system. The voltage sag must be detected and mitigated by implementing a Dynamic Voltage Restorer (DVR). The current works aimed to develop some controlling structures for reducing the voltage sag in the power system. Still, it remains with increased transients, incapability to compensate the mark  voltage, and increased voltage limits. Thus, this paper intends to develop a new controlling algorithm, namely, Synchronous Reference Theory (SRF), for voltage sag mitigation. This Controller's primary considerations are to moderate the voltage sag, analyze the imbalance cutting-edge source voltage, and reduce the harmonic content. Here, the 3-phase load current obtained from the non-mark ar load is given as the input, which is transformed into dq0 reference. The DC quantities are extracted and presented as the input for the extraordinary pass purifyingmethod, eliminating the vocal contents. Then, the SRF controller produces the switching pulses for the Z-source inverter, which reduces the voltage sag. Finally, the presentation of the Controller is evaluated by analyzing the power ingesting and effectiveness.

Authors: Et. al. P.M. Venkatesh,
Published: April 2021

A semi-cylindrical forced convection type solar tunnel dryer (STD) was designed and commissioned at M/s Miraj Products Pvt. Ltd., Nathdwara for drying processed tobacco. Essentially it is based on the mixed mode with direct and indirect type of heating mechanism i.e. the heated air from different solar flat plate collectors is passed through drying cabinet. At the same time, the drying cabinet absorbs solar energy directly through the transparent walls and roofs. It consists of 16×3.75 m2 area, tunnel equipped with 12 solar flat plate collectors of 2 m2 each propelled with 2 exhaust fans of 1 kW capacity placed on both ends of the tunnel. The dryer was tested at no-load and full-load conditions.  During no-load, without flat plate collectors, temperatures inside the dryer were about18-20℃ higher than the ambient temperature during summer day-light, where as in no-load with flat plate collectors, it was about 30℃ higher than the ambient temperature.  A batch of processed tobacco of 500 kg with an initial moisture content 138% d.b. were successfully dried in full load condition to have final moisture content of about 8.7% d.b. in 8 h. It has been observed that STD has many other advantages i.e. getting rid of toxicant gas to labours during opening drying due to lime presence in material, avoidance of product expose to fly contamination and dust concentrations etc.

EFFECT OF PERSONAL BRANDING EFFORTS ON JOB PROSPECTS OF A LINKEDIN USER
Authors: Et. al. Arghyadeep Basu,
Published: April 2021

In this article, the authors examined the relation between Personal Branding efforts in LinkedIn and their job prospects. While there are other social media sites which can be taken into consideration for the study, LinkedIn is deemed to be a purely professional social networking site with content relevant to jobs, industry, economy etc. The authors found that sizable LinkedIn users do not post, share or visit content with the intent of “Building Personal Brand”, however wishes to attract the attention of potential recruiters on the platform. While the term “Personal Branding has been discussed in numerous papers, journals and articles, broader clarity is guaranteed on the same. Additionally, it was duly noted that a person looking for a job doesn’t trust LinkedIn entirely and thus signs up on various other established job portals or seek suitable referrals at the same time.

 

“Your brand has moved online. That means you need to translate who you are in the real world into a congruent bits-and-bytes version of you. First impressions are important to your career success, so whether they take place with a handshake or on a handheld device, you need to make sure yours is authentic, compelling, and relevant.”, said Mitch Joel in his book ‘Ctrl, Alt, Delete’.

 

“It is much more than a style of dress, a particular degree or credential, or the associations to which you belong. Mainly it is the unique “stamp” you put on everything you say or do. Because no one will do things and present themselves in exactly the same way that you do, your uniqueness is what people notice”- Annabelle Reitman and Caitlin Williams on Personal Branding in their periodical journal ‘Distinguish yourself and excel in the profession’.

 

Author Neal Schaffer in his journal “LinkedIn or Left Out” shares his view on LinkedIn by stating- “It is much more than a style of dress, a particular degree or credential, or the associations to which you belong. Mainly it is the unique “stamp” you put on everything you say or do. Because no one will do things and present themselves in exactly the same way that you do, your uniqueness is what people notice.”

 

Further legal trainer Avery Black feels “The most effective way to start your job search is by developing relationships with people. The Internet, through professional websites like LinkedIn and social media sites like Face-book and Twitter, allows people to start a dialogue with each other.”

 

The above quotes individually bring out the core pointers of this literature- “LinkedIn” and “Personal Branding” and “Job Search”. “Branding” which audiences still relate to tangible products have slowly seeped into individuals. Individuals are making informed decisions and suitable actions in order to attract the attention of a specific set of people which in this case are job recruiters.
INDIAN RETAIL INVESTORS AND INITIAL PUBLIC OFFERS: PRE AND POST COVID ANALYSIS
Authors: Et. al. Sreyansh Surana,
Published: April 2021

Going public is one of the most popular forms of raising funds for expansion and growth of business. Since the liberalisation of economy in 1991, more than 1500 companies have listed themselves on the exchange. And the Indian stock markets keep expanding with increasing number of public offers in both mainstream and SME category. This paper compares the IPOs of Indian markets in broadly two phases-pre covid and post covid. A sample of 242 listings across eleven years from 2010-2020 are considered for the study. A comparison based on details of listing, listing gains etc reveal a more active retail investor segment. Overoptimism and urge to synthesise short term gains contribute to such gains. This is further backed by analysis of search results in the Indian region using google trends. Tail events such as covid-19 alter the way Indian investors behave and invest in IPOs and make their investments more on basis of speculative measures such as grey market premium, than actual fundamentals of the issue under consideration.

Published: April 2021

Unparalleled development in information communication technology (ICT) has led people to live in the virtual world.  Smartphone has made peoples’ life more comfortable as they do purchase goods and services while they are on the move. People likely to buy the products online from candy to newspaper. Purchasing newspaper online is currently in a blunder stage, however, steady growth has been reported in the recent past on the purchase of e-newspaper around the world. Therefore, this study aimed to investigate the factors that influence the purchase intention of consumers towards digital/e-newspaper in Sri Lanka. Data were collected for this purpose via a structural questionnaire from those who involve online purchasing either in their home or office in Ampara districts of Sri Lanka. 305 sample response were collected and analysed further with Structural Equation Modelling (SEM) using AMOS. The results revealed that Website Quality (WEBQUAL) and Online Customer Reviews (OCR) post a significant positive influence on the Online Consumer Purchase Intention (OCPI) of the digital newspaper. Meanwhile, Paid Content (PC) was negatively associated with the purchase intention of the digital newspaper which indicates that consumer was not ready to pay the content if it is charged. On the other hand, Trust was not a significant factor as long as e-newspaper purchase is concerned which is a noteworthy finding of this study unlike in the other context such as B2B market or B2C market. The findings of this provide some useful contribution to the literature of consumer behaviour and practitioners like newspaper companies to make a strategic decision on the future business model for digital/e-newspaper in Sri Lanka.
