Published: April 2020

Green marketing is growing at a rapid pace and has become the latest buzzword for the society, where firms are putting extra efforts for a greener world, while adopting latest and innovative production methodology. On the other hand, consumers are equally interested in switching brands or even paying a premium for a greener alternative with a view of indulging in a healthy and safe lifestyle. This study would emphasis on environmental marketing strategies, its sustainability as well as the 4 components of green marketing mix. This paper would highlight the nature of environmental marketing, how imperative it is to produce and sell green products, which initiates a step towards saving our nature with its benefits, while also discussing its inhibitors related to eco-marketing. Nevertheless, this research would analyse the importance and need of green marketing for growing Indian companies, deducing from the fact that not only customers are changing their buying preferences but multinational organizations are also taking mammoth steps to produce green products or services in order to protect depletion of ozone layer.

INVESTIGATION OF THE NEED TO ADJUST THE ROADS DESIGN STANDARDS OF IN QUARRIES
Authors: Loginova I. , Kruzhilko O. , Vinivitin D.
Published: April 2020

The purpose of this work is to justify the need to adjust the standards for designing roads in quarries, taking into account the Rules of labour protection in the development of minerals in an open way. The study is based on domestic (experience in Poltava GOK, Yeristovsky GOK) and foreign (mining enterprises in Australia, USA, Canada) practical experience in operating heavy-duty mining vehicles, as well as on a systematic analysis of current norms for technological design of roads in quarries. An analysis of the regulatory and legal issues related to the safety of operation of heavy-duty mining vehicles showed that the Ukrainian standards for designing roads in opencast mines have not changed 25 years. At the same time, the fleet of technological dump trucks used in quarries, technical characteristics, capabilities and prospects for their use, have significantly changed. The study and identification of the advantages of using roads with a constant slope without the installation of horizontal platforms provides the basis for developing recommendations for updating the design standards for roads in open pits, as the current standards do not meet the requirements for the safe operation of modern heavy-duty mining vehicles. It is proposed to update regulatory legal acts by reviewing them with corrective amendments, taking into account the appropriate level of safety when using heavy trucks. Implementation of the proposed standards to improve the transport scheme of the quarry will contribute to the safe operation of heavy mining vehicles.
A tale of two curricula: learning and matching in the final year of medical school
Authors: Madrazo Lorenzo
Published: April 2020

In this article, I highlight two curricula that I believe are most prominent during the final year of the Canadian medical school experience—that of learning and that of matching to residency. While these two curricula are not mutually exclusive, they can be perceived as contradictory by learners, shifting their focus away from learning towards performing well in an effort to optimize their chance of matching to their program of choice. Moreover, the increasing rates of unmatched students in recent years have likely contributed to this shift while increasing stress and anxiety associated with this final year. In addition to curricular reform, I argue that there needs to be curricular consistency among all stakeholders including undergraduate programs, postgraduate programs, and other third-party organizations.
Bromodeoxyuridine (BrdU) marker for proliferating cells in living tissues: Detection in adult avian brain
Authors: Kumari Yatinesh
Published: April 2020

Knowing how to perform cell proliferation assays is an undeniably essential skill to detect the effect of external or internal stimuli on cell genesis. Immunohistochemical staining using Bromodeoxyuridine (BrdU), enables quantification of proliferative fraction of cells in sectioned tissues. BrdU, an artificial nucleoside that substitutes for thymidine. It is currently quite popular research tool of choice for new cell genesis studies. It incorporates into the DNA during S-phase of the cell cycle that’s why used for birth dating and observing cell proliferation. BrdU immunohistochemistry is currently the most used technique for studying adult cell genesis in situ. In this article we provide a step-by step protocol for immunodetection of BrdU by light microscopy using avian species (Ploceus philippinus); starting from BrdU administration to the final analysis.
Why this time is different: The North Korea Crisis and New Zealand’s interests.
Authors: Steff Reuben
Published: April 2020

North Korea remains the ultimate international outlier: an isolated totalitarian state seeking to acquire a credible nuclear weapons program. As such, a simmering crisis between the North and the US has been playing out since the end of the Cold War. Yet, while past attempts at diplomacy have failed, change is afoot as the Trump administration seeks to shift US-North Korean relations onto a new footing. While skepticism is warranted, this article explains that new personalities and a shift in the structure of power in and around the Korean peninsula provide grounds for cautious optimism that long-term rapprochement is feasible. Small states like New Zealand have a stake in a positive outcome, as its interests dictate that it seeks a stable and secure Asia-Pacific. Furthermore, US-North Korean negotiations take place against the backdrop of intensifying US-China great power competition; a situation that complicates the picture and suggests that long-term peace on the peninsula is only possible if diplomacy takes into account all regional actors. With the above in mind, this article makes a contribution to our understanding of the North Korean issue. It provides a background to the crisis; outlines how personal and structural changes (in terms of the shifting balance of power) suggest that the outcome of diplomatic efforts could be different to failures of the past; considers whether North Korea is an ‘irrational’ actor; and offers a conceptual (and self-avowedly idealistic) framework – ‘strategic liberalism’ – to act as a guide for New Zealand as it looks to calibrate its approach to ongoing tensions and diplomacy on the Korean peninsula.

Neuronal Cell Death Induces Depressive Disorder in Rats Depression-Like Behaviors Caused by Chronic Stress
Authors: Hidayat Rachmat , Saleh Mgs Irsan , Parisa Nita
Published: April 2020

Abstract

Introduction

Depression is believed to be a disorder in which an increase in serotonin activity in the brain. This has implications for the development of various antidepressant drugs that work to increase serotonin levels, by inhibiting serotonin reuptake. However, management with antidepressants is still believed to be not optimal, there are still various problems that have not been able to be solved only by increasing serotonin levels in the brain. Therefore, it is necessary to do further exploration to find out other possible pathophysiology of depressive disorders. This study intended to explore the role of apoptosis of neuronal cells in the prefrontal cortex to answer the hypothesis that depression was not only caused by increased serotonin levels but also  there was a role of dead neuronal cells in the prefrontal cortex which will trigger the body's homeostatic efforts to compensate by increasing serotonin levels.

 

Methods

A total of 30 male Wistar rats (200 ± 20 g) were obtained from Eureka Research Laboratory (Palembang, Indonesia). Experimental animals were placed in cages under controlled conditions (12 hours of light / dark cycles with temperatures of 22 ± 1˚C and humidity of 40-60%), fed and drank ad libitum. Experimental animals with depression model were induced using Chronic Mild Stress (CMS). CMS procedures were performed with mild stressors such as repeated cold stress (4 ° C), space reduction in the homecage, changed cages and social interaction with other animals of the CMS group. To assess wether animal were being depression or not, the animal were tested using Forced Swimming Test (FST). After induction, rats were randomly divided into two groups which each contained 15 animals: the normal control group (not induced CMS) and the CMS group (negative control). Furthermore, the animal model was performed perfusion to maintain organ when evacuation was done, cell damage did not occur. To evaluate cell organ, immunohistochemistry examination and ELISA examination was performed. All data are presented as mean ± standard deviation and all statistical analyzes are performed with the SPSS 25 (IBM) program.

Result

This research showed that CMS animal model has a greater duration of immobility than the normal group and serotonin level in CMS animal models decreased almost threefold compared to the normal group. In addition, there were increased expression of caspase-3 indicates that more neuronal cells suffered from apoptosis. So, in this research, it was clearly stated that in depressive disorder, there were elevation of neuronal cell apoptosis in the prefrontal cortex.

Conclusion

Neuronal cell apoptosis in the prefrontal cortex plays a role in the pathophysiology of depression through activation of negative feedback on serotonin production.

У статті охарактеризовано сучасні глобальні міграційні тенденції в Європі загалом та Польщі зокрема. Ідентифіковано проблемні аспекти та ризики для функціонування й розвитку Польщі під час посилення еміграційних настроїв та внутрішньої мобільності населення цієї держави. Обґрунтовано аспекти виступу української міграції ресурсом вирівнювання трудодефіцтної кон’юнктури на ринку праці Польщі. Наведено офіційні дані Управління у справах іноземців Польщі, Головного управління статистики Польщі, Міністерства сім’ї, праці і соціальної політики Польщі, Департаменту статистики Національного банку Польщі, окремих організацій з вивчення міграції в рамках територіальної міграційної системи «Україна – Польща», на основі яких доведено зростаючі обсяги й масштаби зовнішньої трудової міграції українців до Польщі (показано, що сьогодні в Польщі перебуває близько 1,3 млн. осіб українців, що складає близько 3,5% населення Польщі та є суттєвим значенням), продемонстровано ключові зміни в якісно-структурних характеристиках міграції. При цьому більшість українців перебуває в м. Варшаві та прилеглих до нього регіонах (воєводство Мазовецьке), а також на територіях, які спеціалізуються переважно на сільському господарстві. Охарактеризовано головні параметри еміграції населення України до Польщі, зроблено важливий висновок, що, попри все ще невеликі обсяги, наявні позитивні тенденції та покращуються структурні характеристики еміграції українців до Польщі. Наведено результати аналізу кількісних характеристик трудової міграції українців у контексті їх зайнятості в таких видах економічної діяльності Польщі, як сільське господарство, лісництво та рибальство. Визначено особливості та проблемні аспекти міграції з України до Польщі. Зроблено висновок, що ключові економічні інтереси України та Польщі в системі україно-польської територіальної міграції системи залишаються нереалізованими. Обґрунтовано рекомендації щодо напрацювання спільних українсько-польських практик і нормативно-методичних положень, а також першочергові інструменти міграційної політики, орієнтовані на задоволення соціально-економічних інтересів обох держав.

Ця група підприємств об’єднує такі класи за класифікацією видів економічної діяльності, як виробництво електроенергії, передача електроенергії, розподілення електроенергії та торгівля електроенергією. Діяльність підприємств електроенергетики безпосередньо пов’язана з електроенергетичною системою, частиною якої вона є. Обґрунтовано, що у дефініційному значенні синонімічними є поняття «енергетичне господарство», «єдина енергетична система», «енергосистема національного господарства», «енергетичний комплекс», які застосовуються в енергетиці у значенні системної єдності виробництва, перетворення, транспортування, передачі різних видів енергії, їх розподілення, збуту та споживання. Встановлено, що об’єднує окреслені поняття застосування теорії систем щодо енергетики. Функціонування підприємств електроенергетики багато в чому залежить від управління енергетичною системою на державному рівні, що поєднує державне регулювання та ринкові механізми, включає механізми регулювання природних монополій, тарифної політики відповідно до принципів реалізації суспільних інтересів. Встановлено, що підвищення ефективності функціонування енергетичної системи є можливим тільки за умов досягнення консенсусу між усіма його учасниками, дотримання балансу інтересів між виробниками та споживачами електроенергії. Обґрунтовано, що функціонування енергетичних підприємств багато в чому залежить від створених інституціональних умов розвитку всієї енергетичної системи держави, що поєднує державне регулювання та ринкові механізми, включає механізми регулювання природних монополій, тарифної політики відповідно до принципів реалізації суспільних інтересів.
Os “empoderados” da agricultura familiar

Published: April 2020

O artigo é resultado de uma pesquisa desenvolvida em dois territórios da cidadania do Rio Grande do Norte: Sertão do Apodi e Seridó, com o objetivo de analisar as trajetórias sociais e as disputas de seus agentes por diversas formas de capital, com base nos conceitos do sociólogo Pierre Bourdieu. O campo de relações da agricultura familiar nos dois territórios foi estudado de forma a identificar os conteúdos do discurso dos agentes. O termo “empoderado” foi identificado como designando aqueles que conseguiram se destacar, sendo, de fato, os grandes beneficiados pelas redes de sociabilidade e suas instituições.

Por los caminos del mundo rural:
Authors: Avila R. Agustín
Published: April 2020

El Buen Vivir - jlekil altik para los tojolabales - forma parte de la vida cotidiana de los pueblos, del ejercicio de una territorialidad frente a los intentos de despojo de sus territorios y de los procesos de asimilación cultural. Es también referente a un mundo de vida alternativo que se reproduce y reconstruye en las relaciones sociales que los tseltales y tojolabales ponen en marcha en su vida cotidiana. Por ejemplo el “buen vivir” está muy ligado también al lajan lajan aytik, que significa estar parejos, estar iguales, y que es la aspiración comunitaria de la igualdad. Una sociedad que en la vida comunitaria pone enfásis en la satisfacción de lo necesario y el disfrute de su espiritualidad, hace frente a una economía globalizada que postula la acumulación material desenfrenada, que es causante de la crisis ecológica que vivimos y que no tiene precedentes.
Gestão comunitária de saneamento em comunidades rurais:
Authors: Silva Luciano Cipriano da , Pires Maria Luiza Lins e Silva
Published: April 2020

O presente trabalho analisa o projeto modelo de gestão comunitária de saneamento em pequenas localidades rurais da zona da mata de Pernambuco. Mais especificamente, este trabalho descreve o processo de criação/incubação de duas centrais cooperativas incumbidas, dentro do projeto, de gerir o sistema de saneamento da região da zona da mata pernambucana. Como está se dando o processo de implementação do projeto modelo de gestão comunitária e saneamento e quais as principais dificuldades enfrentadas nesse processo? Para responder a essas questões, estabeleceu-se um itinerário de pesquisa que dá particular destaque às políticas públicas voltadas para o meio rural, dentro da perspectiva de promoção da universalização do acesso ao abastecimento d ́água e ao saneamento, na relação com o desenvolvimento local. A análise revelou as tensões, dificuldades e avan- ços presentes em cada etapa de execução do projeto, as disputas políticas para a escolha da equipe diretora das centrais, a destituição de um presidente eleito e a formação de uma nova chapa, a criação do estatuto e sua aprovação pelo conjunto dos sócios, o registro dos Estatutos em cartório e a instalação provisória dos grupos nas sedes das entidades. Também foi revelada a insatisfação da direção de ambas as centrais com a morosidade na conclusão do processo. Tal problemática constitui um labo- ratório para se refletir sobre as políticas públicas no Brasil, sobretudo sobre o caráter inconcluso de muitas delas. Nesse campo, reside a importância maior deste estudo.
Ancestralidade, trabalho, terra:
Authors: Nascimento Rogério Humberto Zeferino
Published: April 2020

Neste artigo apresento aspectos históricos, sociais e da ordem do simbólico, constitutivos de dois quilombos do estado da Paraíba: Pedra D’água e Vaca Morta. Localizados, respectivamente, no agreste e sertão, ambos possuem trajetórias diferentes, mas também aspectos comuns. No primeiro quilombo, o ancestral fundador, Manuel Paulo Grande, evadiu-se para a mata dos arredores da cidade de Ingá para fugir das perseguições policiais por conta de seu envolvimento com o Movimento Quebra-Quilos (1874). No segundo quilombo, o ancestral fundador, Manuel Severino, sob ordens do patrão, saiu do estado do Ceará no ano de 1905 para administrar as terras da Paraíba. O patrão possuía vastas quantidades de terras nos dois estados. Neste caso, sua descendência estabelecida numa de suas fazendas, continuara com os patrões a relação de subalternização negociada. Mesmo com processos históricos particulares, os integrantes dos dois quilombos, de forma recorrente, evocam em suas memórias e narrativas a figura do ancestral fundador enquanto referencial primordial enlaçando, através das relações de parentesco biológico e espiritual, a vida de todos e de cada um. Ao mesmo tempo, em suas narrativas o sentimento de pertença é afirmado e reforçado pelas lembranças partilhadas quanto ao trabalho naquelas terras. Trabalho este realizado pelas gerações de seus descendentes, incluindo a atual. O trabalho produtivo e gerador de alimentos e bens das várias gerações, moldara e transformara a terra. Ainda outro elemento importante fortalecendo o sentimento de pertença diz respeito ao campo do sagrado. Nos dois quilombos, seus integrantes apontam alguns locais como marcos significativos dos que morreram como também do dever da devoção. Por fim, a dinâmica das relações interna e com a sociedade envolvente, passa por estratégias coletivas. Estas, por sua vez, são orientadas pelo parentesco, fonte importante do sentimento de grupo, como também pela memória coletiva depositada nos mais velhos e partilhada por todos.

Este artigo apresenta o turismo em Terra Indígena (TI) abrangida na rede resistência de povos e comunidades tradicionais do Ceará. Nesta parceria expande-se o turismo comunitário na Zona Costeira do estado, adverso aos projetos de turismo global implantados ao longo do litoral cearense. Destaca-se a situação dos Jenipapo-Kanindé da TI Aldeia Lagoa Encantada, que enfrentam desde 1997 o letárgico processo de demarcação da sua terra junto ao Estado Nacional. Embora a TI ainda não homologada, este povo indígena impediu a construção do Aquiraz Resort no seu território tradicional e, implantou o próprio projeto de turismo comunitário na aldeia. Os Jenipapo-Kanindé para evitar a edificação do empreendimento turístico Luso-brasileiro na TI, afirmou a identidade indígena e, expande as atividades turísticas como meio de vida e manifestação da sua afirmação étnica.
Patrimônio cultural, representação e poder:

Published: April 2020

O presente trabalho discute a atuação dos antropólogos em pesquisas que subsidiam processo de patrimonialização, especialmente nas pesquisas promovidas pelo IPHAN, no contexto do Inventário Nacional de Referências Culturais - INRC. Inicialmente, procuro situar diferentes momentos das políticas de patrimônio no Brasil, mostrando que a atuação dos antropólogos ou de uma perspectiva antropológica no campo do patrimônio cultural acompanha o próprio alargamento desse conceito, com o advento de novas narrativas nacionais sobre patrimônio e com o protagonismo dos bens de caráter imaterial. Em um segundo momento, abordo a pesquisa de campo em inventários patrimoniais, situando diferentes dimensões, quase sempre conflitantes, presentes na prática do antropólogo. Concluo o artigo apresentando alguns desafios teórico-metodológicos para o campo do patrimônio cultural, considerando que alguns conceitos nele implicados estão (há décadas) sendo repensados e o fato de não lidarmos mais com realidades fixas, localizadas e simbolizadas, mas com culturas e identidades em fluxo e trânsito constantes.
“Seguimos todos no barquinho”:
Authors: Magalhães Eloi dos Santos
Published: April 2020

O objetivo deste artigo é analisar a expressão de um tipo de comunalização religiosa aliada à compreensão do “habitus religioso” (Bourdieu, 2007) gerado segundo as injunções das relações associativas e das práticas devocionais realizadas no “Centro Espírita e Culto de Oração Casa de Jesus – Fonte de Luz”. O respectivo culto foi fundado, no ano de 1945, em Rio Branco (capital do Acre), por Daniel Pereira de Mattos, proveniente do estado do Maranhão. A pesquisa que fundamenta o presente estudo resulta de material de campo, notadamente à luz das considerações de Berreman (1975) e Clifford (1999), além das perspectivas de pesquisa histórica sugeridas por Burke (2004) e Ginzburg (2006). Considera-se, então, que o vínculo duradouro ao culto incrementa um habitus religioso particular a partir da regularidade das práticas devocionais próprias com o uso ritual da ayahuasca, assumidas, então, como compromissos canalizadores de um preparo específico.

Published: April 2020

O artigo retrata controvérsias associadas ao conceito de campesinato que se desenvolveu no Brasil no âmbito de reflexões sobre ruralidades contemporâneas. A partir de uma pesquisa bibliográfica sobre o lugar do campesinato no pensamento social brasileiro, foi privilegiada uma abordagem histórica e uma leitura sociopolítica da modernização conservadora da agricultura e de suas consequências expropriadoras. Salientou-se a trama de tensões presente sobre diferentes aspectos na questão agrária e fundiária brasileira. Partindo do rural como um espaço de diversidade social, o artigo recupera dimensões do modo de vida camponês, tomando como princípio metodológico a superação de dicotomias e de uniformidades na compreensão das experiências e dinâmicas familiares no rural brasileiro.
