Vizuālā tēla neaizskaramības sociāli bioloģiskie apsvērumi
Authors: Krilova Sabīne , Ziemelis Andris
Published: August 2020

Cilvēka vizuālais tēls iemanto apjomīgu sociāli bioloģiskās informācijas daudzumu. Tas norāda uz dzimumu, vecumu, rasi, veselības stāvokli, auglību, hormonu līmeni un pat uz paredzamo uzvedību un dzīves ilgumu. Tā ir būtiska privātā informācija, kas ikdienā nav aizsargāta un kas ir eksponēta apkārtējiem. Latvijā katrs trešais skolēns saskaras ar mobingu, un tas ir viens no augstākajiem rādītājiem starp Ekonomiskās sadarbības un attīstības organizācijas valstīm. Piemēram, visticamāk, tieši mobings bijis par iemeslu 16 gadu veca puiša pašnāvībai, kas notika 2019. gadā. Zināms, ka pašnāvība ir sociālās atstumtības rezultāts, un Latvijā ir trešais lielākais pašnāvību izdarījušo cilvēku skaits Eiropas Savienībā. ﻿﻿Rakstā tiek analizēta vizuālā tēla sociāli bioloģiskā koncepcija, sniegti argumenti tā aizsardzībai un nozīmīgumam sabiedrībā kopsakarā ar spēkā esošajām tiesību normām un judikatūru. Nobeigumā ir priekšlikums, kas attiecināms uz likumprojektu “Sejas aizsegšanas ierobežojuma likums”, kā arī uz sejas atpazīšanas videonovērošanas sistēmas iespējamu ieviešanu.

﻿﻿Visual image of a man is a considerable amount of socially biological information. This includes gender, age, race, health, fertility, hormone levels, even behavior, and life expectancy. It is essentially private information that is not protected day-to-day basis and is rather exposed to the surrounding individuals. In Latvia, every third pupil faces bullying, which is one of the highest rates among OECD countries. For example, in 2019, it was more likely that bullying had been the reason for suicide of a 16-year-old boy. It is known that suicide is the result of social exclusion, and Latvia possesses the third largest number of people who have committed suicide in the European Union. ﻿﻿The article analyses socio-biological concept of visual image, arguments for its protection and its importance in society, compliance with existing legal provisions and case law. A proposal has been made for the establishment of legal provisions relating to the draft of the Facial Masking Limitation Law, as well as for the possible introduction of a facial recognition video surveillance system.
Consumer Rights and Personalised Advertising: Risk of Exploiting Consumer Vulnerabilities
Authors: Dāvida Zanda
Published: August 2020

Have you ever received a frighteningly personalised advertisement with a specific product at the moment when you are thinking about buying that product? Digital technologies have huge positive potential, but their uncontrolled use poses many risks. However, the notion that the current direction of technological development is unavoidable and that the problematic aspects of technology simply need to be tolerated poses a much greater threat to the future. Therefore, this paper discusses one of the risks – personalised advertising that seeks to exploit consumer vulnerabilities. Thereby, the aim of the article is to analyse legal problems of targeted and personalised advertising that seeks to exploit consumer vulnerabilities and to propose ways to solve the identified problems. In the article, the author puts forward a thesis (hypothesis) that consumers should be protected from personalised and targeted online advertisements that seek to exploit their vulnerabilities. The hypothesis of the article is confirmed. Therefore, the article identifies four ways that, in the author’s opinion, will improve or will provide consumer protection from personalised advertising that seeks to exploit consumer vulnerabilities. In addition, to fully reach the aim of the article, the author analyses the concept of consumer vulnerability. In brief, the article affirms that all of us can be vulnerable in a situation. Therefore, the article applies to all of us.

Vai Jūs kādreiz esat saņēmis biedējoši personalizētas reklāmas ar konkrētu preču vai pakalpojumu piedāvājumiem tieši tajā brīdī, kad Jūs domājat par šīs preces vai pakalpojuma iegādi? Digitālajām tehnoloģijām ir liels pozitīvs potenciāls, bet vienlaikus tās rada daudzus to nekontrolējamas izmantošanas riskus. Tomēr daudz lielākus draudus nākotnei rada uzskats, ka pašreizējais tehnoloģiju attīstības virziens ir neizbēgams un ka tehnoloģiju lietošanas negatīvās blaknes ir vienkārši jāpieņem. Šī raksta ietvaros tiek analizēts viens no šiem riskiem, proti, tehnoloģiskā prakse attiecībā uz personalizētajām reklāmām, kuras balstās vai ir tendētas uz patērētāja mazaizsargātības (ievainojamības) izmantošanu, kā arī analizēta šīs prakses tiesiskā problemātika un piedāvāti identificēto problēmu risinājumi. Rakstā tiek izvirzīta hipotēze, ka patērētāji ir jāaizsargā no šādām personalizētām reklāmām, un piedāvāti četri tiesību izpratnes veidi, kas varētu uzlabot patērētāju tiesību aizsardzību no tām. Lai pilnībā atklātu raksta mērķi, papildus tiek analizēts patērētāja mazaizsargātības koncepts, savukārt secinājumos apstiprināts, ka mēs visi varam būt mazaizsargāti kādā konkrētā situācijā. Līdz ar to šis raksts ir aktuāls mums visiem.
Blessing’s (Life) Story: An Adolescent in Residential Care Living with HIV
Authors: Chiba Jenita , Schmid Jeanette
Published: August 2020

The lifespan of perinatally HIV-infected children in South Africa has increased owing to the availability of antiretroviral treatment, allowing growth into adolescence and beyond. There is limited knowledge of the lived realities of adolescents with HIV. This paper, using life story methodology and based on Blessing’s narrative, provides an intersectional, complex view of the experience of one such teenager who is perinatally HIV-positive, was abandoned by his family and is living in a residential care facility. His story powerfully illuminates the specific construction of adolescence in this context, focusing on identity formation and the need for connection. The narrative also points to service providers’ practice when engaged with such youths.
Social Work Services by Non-Profit Organisations for Adults with Substance Use Disorders
Authors: Carelse Shernaaz , Green Sulina
Published: August 2020

Social work services globally started as a result of society’s response to basic human needs, and thus facilitated alleviating, based on doing good, the plight of those in need. Since its inception as a professional discipline, social work has always been associated with poverty relief and services to persons with substance use disorders (SUDs). The high prevalence of SUDs in South Africa makes it one of the top 10 substance abusing countries globally. As such, the demand for social work services, aimed at substance abuse intervention, has increased rapidly over the past 20 years, resulting in the emergence of many non-profit organisations (NPOs). However, there are gaps in evidence-based research on social work services provided by NPOs to persons with SUDs. The focus of the article is on the nature and scope of social work services provided by NPOs to adults with SUDs. The population for the study was supplied by NPOs across the Cape Metropole, offering services to persons with SUDs. Semi-structured interviews were conducted with 10 social workers, purposively selected from 10 NPOs across the Cape Metropole. Thematic data analysis was done and yielded three main themes, namely theoretical approaches, levels of intervention, and methods in social work practice when delivering services to adults with SUDs.
Childhood Family Environment and Depression in Early Adulthood in Botswana
Authors: Mongale Neo , Amone-P'Olak Kennedy
Published: August 2020

The childhood family environment is a determinant of mental health outcomes later in life. Yet, few studies have examined its role in outcomes such as depression in early adulthood, especially in low- and middle-income countries such as Botswana. This study explores the relationship between childhood family environmental factors and depression among young adults in Botswana. A sample of 351 students at the University of Botswana was surveyed through a self-administered questionnaire, which included various childhood environmental factors, the Beck Depression Inventory-II and socio-demographic items. Descriptive statistics, t-tests and regression models were used in the data analyses. About one in four young adults reported moderate to severe symptoms of depression with about one in ten in the severe category. Childhood alcohol use, parental drug and alcohol use, physical assault, and psychological aggression towards parents or guardians during childhood, all significantly predicted symptoms of depression in early adulthood. Altogether, the childhood family environmental factors and gender explained significant variance in depressive symptoms. Multiple adverse childhood environments constitute significant risk factors for depression in early adulthood and the next generation. Preventive and early intervention services for vulnerable children, evaluation of mental health, childhood family experiences, and creating awareness of the need for treatment are critical. Cognitive behavioural therapy and mindfulness training are possible strategies to reduce the life-course effects of adverse childhood family environmental factors on depression in young adults.
Volunteers as Enablers or Disablers of Community Development in Chegutu District, Zimbabwe
Authors: Kabonga Itai
Published: August 2020

This paper analyses the potential contributions of volunteers to community development. Little is known about the contribution of volunteers to community development although almost every non-governmental organisation in Zimbabwe relies on volunteers. This research used a qualitative approach with in-depth interviews, key informant interviews and focus group discussions to collect data from community volunteers, officials of non-governmental organisations, and government officials. Community volunteers play an important role in driving and sustaining community development. The researcher established that volunteers act as an intermediary between the community and non-governmental organisations. Moreover, activities like the targeting of beneficiaries and the implementation of activities are unthinkable without the involvement of volunteers. Despite volunteers’ importance, there are serious drawbacks that influence the effective contribution of volunteers to community development. Volunteers disable community development through corruption, polarisation, falsifying reports and a lethargic approach to work. These drawbacks contradict the ubuntu value system that underlines the concept of volunteerism. Some of the drawbacks can be rectified by incentivising community volunteers, and by recruiting volunteers with acceptable levels of literacy.

Published: August 2020

Rheumatoid arthritis (RA) is an autoimmune disease causing severe joint damage, disability and decreased quality of life. Pathologically, numerous blood-derived cells infiltrating in synovium and cytokine secret necessitating formation of new blood vessels to generate pannus together form an inflammatory microenvironment. Triptolide with immunosuppressive activities is a potential drug to treat RA. However, it is still lack of an effective targeting system to deliver triptolide to RA site safely. Herein an inflammatory microenvironment targeting and remodeling nanoplatform is developed to achieve significantly effective RA treatment. In this system we synthesized a self-assembling triptolide nanoparticles (TPNs) mediated by dipeptide diphenylalanine which is the simplest self-assembly building block, then TPNs were entrapped by mannose-modified erythrocyte membranes to form engineering manRTPNs. For targeting, the immunological molecule of erythrocytes was firstly introduced to target T cells by ligand binding of LFA-3/LFA-2, and the coated mannose modified erythrocyte membrane also conferred the capacity of targeting to macrophages by mannose and its receptor CD206; for remodeling inflammatory microenvironment, TPNs could selectively exert its suppressive effects on different cells of RA including lymphocytes and synovial fibroblasts. In collagen

induced arthritis mice, manRTPNs showed excellent targeting effect and prolonged accumulation at inflamed joint. After manRTPNs treatment, swollen paws of CIA considerably shrunk to normal, boss loss even recovered healthy level and cartilage preserved at synovium cavity, because of systemically conventional cytokine reduction and expression shift of core genes in networks of RA microenvironment. Therefore, this well-defined manRTPNs might be a well promising systematic therapeutic agent for RA.

Published: August 2020

Polymeric carbon nitrides (PCNs) have emerged as promising heterogeneous photocatalysts for organic transformations as they are metal-free, inexpensive, and possess suitable bandgaps, and excellent chemical- and photo-stability. However, current application of PCNs in organic synthesis is rather limited to several well-established materials, which limits the scope of reaction patterns and efficiency. We herein report the synthesis and fabrication of two new PCN nanosheets by incorporating nanostructure construction, element doping, and vacancy engineering into one hybrid platform. The heteroatom doped PCN nanosheets with vacancies feature highly porous structures with extremely large substrate-catalyst interface areas, enhanced charge separation, and improved lipophilicity. The generated heterogeneous catalysts demonstrate impressive photoredox catalytic performances in a variety of organic transformations (e.g., defluoroborylation, [2+2] cycloaddition, C-N, C-S, and C-O cross couplings), providing efficiencies comparable to reported optimized homogeneous catalysts and exceeding those with commonly utilized PCNs.

Nutritional and functional properties of dried Momordica cochinchinensis Spreng. fruit aril and its application in cheese spread production
Authors: Carbonera A.F.A. , Tayobong R.R.P. , Barrameda L.I.C. , Miranda A.M.V.
Published: August 2020

Momordica cochinchinensis Spreng. is an underutilized fruit-bearing indigenous plant in
the Philippines with great potential due to its reported nutritional properties. The aril
portion of the fruit was used because of its high carotenoid content. The aril was dried
using oven drying (60°C) and freeze drying methods to a final moisture content of 15%,
and then compared in terms of its lycopene, β-carotene, and Vitamin A contents as well as
antioxidant activity. To determine the potential of the dried aril as an additive to produce a
fortified product, it was added at an amount of 4 g per 100 g of cheese spread then its
nutritional properties were evaluated. Results showed that freeze dried aril has high βcarotene (2090.28 µg/g) and Vitamin A (3483.80 IU/g) but is not significantly different
than the oven-dried aril while the oven-dried aril has significantly higher lycopene content
(405.22 µg/g) than the freeze dried aril (325.84 µg/g). Furthermore, the freeze dried aril
has significantly higher antioxidant activity (29.81%) than the oven-dried aril (16.27%).
The addition of the dried aril to cheese spread resulted to a product with significantly
higher lycopene (30.15 µg/g), β-carotene (24.93 µg/g), Vitamin A (41.55 IU/g), and
Vitamin C (1.20 mg/100 g) compared to the cheese spread with no aril powder. Thus,
a serving size of 1 tbsp (20 g) of the cheese spread with aril powder can provide 17% daily
value for Vitamin A and has satisfied the definition of fortified food as well as the USDA
standard reference for Vitamin A. This functional ingredient can therefore address
concerns on Vitamin A deficiency.

Published: August 2020

ABSTRAKPengurangan gaya prategang yang diperlukan pada suatu penampang beton prategang penuh (full prestressed) menyebabkan diperlukannya baja tulangan, dan beton prategang berperilaku menjadi beton prategang parsial. Pengurangan gaya prategang akan menimbulkan tegangan tarik yang bilamana tegangan tarik yang terjadi melampaui kuat tarik lentur beton maka akan terjadi retak. SNI 03-2847-2002 membolehkan penggunaan beton prategang parsial namun belum mensyaratkan batasan persentase prategang yang harus digunakan. Oleh karena itu dilakukan studi analisis untuk mengetahui persentase prategang minimal yang dapat digunakan. Studi kasus dilakukan pada persentase prategang 50, 60, 70, 80, dan 90. Dari hasil studi kasus didapatkan bahwa persentase prategang yang semakin kecil akan berakibat tegangan tarik dan lebar retak yang terjadi semakin besar. Persentase prategang harus dipilih sedemikian rupa sehingga lebar retak yang terjadi tidak melampaui lebar retak yang diizinkan. Pada kelima variabel penelitian, batasan minimal persentase prategang yang lebar retaknya tidak melebihi lebar retak yang diizinkan adalah 60%.Kata kunci:  beton prategang parsial, persentase prategang, tegangan tarik, lebar retak ABSTRACTReducing the required prestressing force on a full prestressed concrete section requires the need for reinforcing steel, and prestressing concrete behaves to partial prestressed concrete. Reduction of the prestressing force will cause tensile stress when the tensile stress that goes beyond the tensile strength of the concrete will result in cracking. SNI 03-2847-2002 allows the use of partial prestressed concrete but does not require the limitation of the prestress percentage to be used. Therefore, an analytical study was conducted to determine the minimum prestressed percentage that can be used. The case study was carried out at 50, 60, 70, 80, and 90 prestressed percentages. From the case study it was found that the smaller the prestress percentage would result in greater tensile stress and crack width. The percentage of prestress shall be chosen so that the crack width does not exceed the allowable crack width. In the five research variables, the minimum limit of prestressing percentage whose crack width does not exceed the allowable crack width is 60%.Keywords: partial prestressed concrete, prestress percentage, tensile stress, crack width
