LEGALITY OF DECISIONS TAKEN BY THE SUBJECTS OF OPERATIONAL AND INVESTIGATIVE ACTIVITIES: ON THE QUESTION OF THE LEGAL NATURE
Authors: Babichev Dmitriy A.
Published: August 2020

The article deals with the problem of determining the legal nature of the decisions taken by the bodies engaged in operational investigative activities. Stating the amorphousness in the relevant scientifi c research, the author refers to the doctrinal ideas about the essence of legality in the fi eld of operational and investigative activities. On the basis of a critical analysis of the provisions set forth in the most cited dissertations, monographs, textbooks, as well as in the comments to the Laws of the Russian Federation «On the Prosecutor’s offi ce of the Russian Federation», «On operational investigative activities», a number of judgements are put forward. It is stated that the rule of law is a social and legal phenomenon, which can be considered to be a principle, a method or regime. Legality as a phenomenon develops and changes together with society, law and the state. Understanding and interpreting the rule of law often does not take into account the conceptual shifts in the architectonics of legal regulation that have occurred in post-Soviet Russian legislation. The author comes to
the conclusion that the modern conditions for the implementation of operational and investigative tasks dictate the urgent need to clarify and even revise the essence of legality by moving from a narrow to a broad understanding of its legal nature.
In particular, preference is given to the legal approach, which implies subordination of the rule of law to higher legal principles and ideals, for example, justice.

TAKING INTO ACCOUNT THE VISCOELASTIC PROPERTIES OF THE CONTACT WHEN MODELLING DAMPING IN TEXTILE MATERIALS
Authors: Bukina S. V. , Gromova E. I.
Published: August 2020

An attempt is made to determine the mechanical properties of a static contact by studying it dynamically by means of tangential stresses and strains, which is, according to the authors, the most appropriate, since tangential stresses and strains are the result of a complex of processes occurring on the contact and they depend on the load, contact temperature , the actual contact area, as well as the mechanical properties of the surface layers of the friction pair, etc. Taking into account the viscoelastic properties of the contact allows one to increase the accuracy of modelling the processes of energy loss in the contact of textile materials and inside textile structures, such as wound body tissues, etc. The proposed approach will be of interest to specialists in the field of mechanical engineering, as well as specialists in the field of textile technologies.

Authors: Naganathan Hariharan , Sauer Aaron D , Chong Oswald , Kim Jonghoon
Published: August 2020

Transportation sustainability is centered on being the linchpin to cultivate innovations and enhance safer environmental standards. The public and private agencies adopt sustainable practices integrating their policies in order to elevate sustainability performances. There is an advent need of developing a tool for quantifying the transportation policies and practices. This paper explains (1) the fundamental practices adopted by different transportation agencies; (2) the impacts of three pillars on developing the sustainable indicators; (3) the selection of indicators and their grouping; and (4) the statistical relationship between indicators with the real-time variables population and GDP. This performance benchmark aims to quantify the sustainability practices of the state and its transportation agencies by assessing their environmental, social, and economic practices. The paper examines the relationship between the selected sustainable indicators and establishes the framework for the sustainability of transportation. This framework is a starting point for adding more relevant indicators to measure the sustainability of transportation when data become available.
Caregiver Burden among the Caregivers of Older Adults with Palliative Care Needs
Authors: Humera Khojji , Ali Sathiq , Bhat Shruthi , Adhikari Prabha
Published: August 2020

Objective: To examine caregiver burden among caregivers of hospitalised geriatric patients with palliative care design. Method: Caregivers of 330 geriatric patients with various chronic end-stage diseases were assessed using BSFC-s questionnaire. Results: Majority of caregivers were spouses (26%). The caregiver burden across the categories was more than 60% across all the questions asked in the BSFC-s questionnaire. Maximum in the caregiver with end-stage renal disease (60.3%) and a minimum of frail elderly (50.2%).
Conclusion: Caregiver burden was common in caregivers of geriatric patients with end-stage chronic diseases. The burden was associated with the caregiver’s report of need for greater help with daily tasks but not with objective measures of the patient’s need for assistance, such as symptoms or functional status, suggesting that burden may be a measure of the caregiver’s ability to adapt to the caregiving role.

Authors: Masood Syed Mohammed , Adhikari Prabha
Published: August 2020

Objectives: To study the prevalence of Geriatric giants among elderly attending Geriatric clinic of YMCH and
to study the various factors (like Age, gender, co-morbidity, etc.) associated with these Geriatric giants.
Method: This retrospective study was conducted in a tertiary care referral centre, from the year 2018 to 2019,
Ethics committee approval was taken wide letter no. YEC-1/29/2020 (Protocol YEC2/162). Two hundred two
geriatric patients, presenting to the geriatric clinic with geriatric giants, with various co-morbidities, their
data was recorded. Falls in the previous year and urinary incontinence were recorded. Polypharmacy is
considered as concurrent use of more than four drugs. Diagnosis of dementia and depression was conducted
according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition diagnostic criteria. All
the proportions were expressed as percentages; mean ± SD were used for Numerical Data. Factors such as age
group, gender, morbidity index (number of morbidity present) which are related to geriatric giants were
assessed using the Chi-square test. Results: The frequency of urinary incontinence was 75.7%, depression
was 69.3%, falls were 67.3%, dementia was 47.5%, and polypharmacy was 33.6%. When all the participants
were divided into four groups age-wise, respectively (60-69, 70-79, 80-89, 90-99 years), all syndromes were
significantly increased with age. While a significant number of cases in the 60-69 years age group did not have
any syndromes, more than 50% of cases in ≥80 years had more than three geriatric syndromes simultaneously.
Conclusion: The frequency and coincidence of geriatric giants, except for polypharmacy, increases with age.
Therefore, clinicians other than the geriatricians taking care of older people should be aware of these
syndromes as well as their treatment mechanisms

Community Perception about Children with Hydrocephalus in Lagos State, Nigeria
Authors: Bakare Mistura A.
Published: August 2020

This study which was anchored in Health Belief Model and Functionalism investigated the perceived cause of hydrocephalus and the influence of socio-demographic characteristics on such perception. Data were collected through questionnaire survey, Focus group discussions (FDGs), In-depth Interviews (IDIs) and Key Informant Interviews (KIIs). Results indicate that perception about the cause of the condition included that it is a kind of punishment for sin (50%), spiritual attacks (27.3%), genetic (13.7%) and infection (9%). Community perception was higher especially with respondents age 42-47 (OR=1.32), female (OR=1.47), tertiary education (OR=0.69), punishment for sin (OR=0.61), spiritual attacks (OR=0.26) and infection (OR=0.48) than genetic factor. Community belief that hydrocephalus does not require medical attention negatively affected seeking medical help early. Other limiting factors were fear of surgical complications, inability of mothers to take responsibility; poor family social supports system and stigmatisation. There is need for stakeholders and agencies to enlighten community members on hydrocephalus and provide social support for children with the condition.
Are we not Reinventing the Wheel?: Reviewing Literature in Social Science Scholarship and the Imperatives of Aligning with Global Best Practices
Authors: Nwokocha Ezebunwa E.
Published: August 2020

This paper examines the contexts of literature reviewing among scholars in Africa, particularly social scientists. It argues quite forcefully that reviews are becoming increasingly characterized by avoidable gaps and therefore represent some form of enigma, which remain largely unrecognized. The implications are not only debilitating but also alienating from the global intellectual milieu. The paper chronicles the issues and suggests the path to achieving standard reviews in contemporary academic scenery, rather than reinventing the wheel and, by implication, demeaning the essence of knowledge production and propagation.
Migration Status, Reproductive Behaviour and Fertility in the City of Port Harcourt, Rivers State, Nigeria
Authors: Akpandara Tarilaifa P. , Isiugo-Abanihe Uche C. , Fayehun Olufunke
Published: August 2020

This paper examined migration status and reproductive behaviour and fertility of women in Port-Harcourt, Rivers State, Nigeria. The study contends that fertility behaviour of urban women is better understood when examined within the contexts of system and voluntary social action analysis. The study reveals that migrants have lower fertility than non-migrants. This is in the expected direction even though the relationship is not statistically significant. Among the reasons, migrants are generally more progressive and tend to exhibit higher levels of motivation with respect to family and lifestyle matters, being better educated and with higher levels of aspiration. The major childbearing behaviours, such as age at first marriage, ideal birth interval, ideal length of breastfeeding and knowledge, attitudes and contraceptive use, were found to be relatively higher among migrants than non-migrant women. Again, these differences are hardly significant, partly due to the small sample size analysed here.The result of this study could warrant a possible future fertility decline among migrants, but also not excluding the non-migrants, if the current level of use of contraceptives continues to improve. The effects of these factors may translate into low urban fertility desires and the adoption of small family size norms in the nearest future
“She was neither unduly fat nor lanky”: Representation of body size and beauty in the novels of Daniel O. Fágúnwà
Authors: Ibrahim Fausat Motunrayo , Jegede Ayodele S.
Published: August 2020

The climate of thought regarding beauty characterization among Africans and other people of colour portrays the large body as beautiful. This reflects that body size and beauty is racially and culturally expressive, making it apposite to be disparate in advancing related discourses. This is particularly important because such discourses can influence Africans’ evaluation of their self-worth. The concerns generated by the global rise in obesity further create interest in these issues. African literature offers a fine and disparate platform to understand social realities. Consequently, relevant contents of the five precedent Yorùbá novels of Daniel Fágúnwà including Igbó Olódùmarè, Ìrèké Oníbùdó,Ògbójú ọdẹ nínú Igbó Irúnmọlè, Ìrìnkèrindò nínú Igbó Elégbèje and Àdììtú Olódùmarè were extracted and analyzed to examine association of beauty with body sizes. Findings reflect more of bipolarity in the definition of beauty, such that the none-fat/none-thin structure is conveyed as beautiful. Concurrently, the fat and the thin is also portrayed as beautiful, making ‘body size’ definition of beauty to be elusive, and strongly suggesting neutrality to body size among the Yorùbá. This is strongly borne out of Fágúnwà’s and indeed, Yorùbá construction of beauty from a ‘character’ perspective. Character (ìwà) is staunchly expounded as constituting beauty. The beautiful body size is indeterminate in Fágúnwà’s narratives and indeed, in Yorùbá thought.
Randomized heuristic for the maximum clique problem
Authors: Shah Shalin
Published: August 2020

A clique in a graph is a set of vertices that are all directly connected

to each other i.e. a complete sub-graph. A clique of the largest size is

called a maximum clique. Finding the maximum clique in a graph is an

NP-hard problem and it cannot be solved by an approximation algorithm

that returns a solution within a constant factor of the optimum. In this

work, we present a simple and very fast randomized algorithm for the

maximum clique problem. We also provide Java code of the algorithm

in our git repository. Results show that the algorithm is able to find

reasonably good solutions to some randomly chosen DIMACS benchmark

graphs. Rather than aiming for optimality, we aim to find good solutions

very fast.
Analysis of E-Commerce Product Graphs
Authors: Shah Shalin
Published: August 2020

Consumer behavior in retail stores gives rise to product graphs based on copurchasing

or co-viewing behavior. These product graphs can be analyzed using

the known methods of graph analysis. In this paper, we analyze the product graph

at Target Corporation based on the Erd˝os-Renyi random graph model. In particular,

we compute clustering coefficients of actual and random graphs, and we find that

the clustering coefficients of actual graphs are much higher than random graphs.

We conduct the analysis on the entire set of products and also on a per category

basis and find interesting results. We also compute the degree distribution and

we find that the degree distribution is a power law as expected from real world

networks, contrasting with the ER random graph.
