Authors: Jiang Lina , Zhong Jingdong
Published: May 2024

Walden is a literary masterpiece written by American writer Henry David Thoreau (1817-1862), which records his living alone in Walden Pond, far away from money-obsessed society, embracing the simple life of nature with his heart, and demonstrating the harmonious ecological beauty of Walden Pond. In this novel, Thoreau vividly shows the harmonious and interdependent relationship between man and nature through the ecological pictures of the delicious evening and red squirrel in the Walden Pond, and emphasizes the unique spiritual value given by nature to human beings. This paper attempts to use literature research and graphic marking ways to appreciate the harmonious atmosphere of delicious night in Walden Pond and the lively state of red squirrels in winter from the Angle of plot and animal description. By combining theory with practice, the conclusion of this paper is: human beings should overcome the limitations of anthropocentrism, protect animals, respect nature, and establish a “community of love” with nature, the concept of harmonious coexistence between humans and nature, or they will be punished by nature. In-depth exploration and interpretation of Walden Pond is of great significance for enhancing people’s awareness of ecological crisis, promoting ecological governance, helping people rationally view the relationship between man and nature, and respecting and protecting nature.

Plant pathogens are a significant and urgent issue mainly in agricultural countries. Disease control using chemicals and antibiotics can cause widespread negative impacts, particularly on fresh vegetables and agricultural raw materials. These could affect national food insecurity. Antimicrobial peptides (AMPs) are one of the effective solutions because of theirs remarkable antimicrobial action mostly on bacteria and fungi, the primary causes of plant-infected diseases. AMPs are present in common living things, both in prokaryotes and eukaryotes, these are the natural defenses in organisms. Each type of AMPs exhibits distinct microbial targets through various mechanisms. Some AMPs kill microbes in a few seconds after contact with target cells, some AMPs stimulate the antibiotic effects, while some AMPs exhibit superior results than antibiotics. AMPs work by two different mechanisms: the direct bactericidal mechanism that involves interaction with the bacterial membrane and results in cell lysis, and the indirect bactericidal mechanism that involves penetration without causing cell lysis but inhibiting the synthesis of DNA, RNA, and proteins. Current AMPs research reveals promising outcomes at the laboratory level. Further studies will focus on the actual environment and the outbreak area respectively.

Published: May 2024

This study investigates how work motivation and competency impact employee performance at a marketing-related organization. The research focused on work motivation and competence because these factors are critical in determining an individual's success within the organization's framework. The regression analysis method examines Employee performance in connection to these variables.
Based on the research findings, motivation has a total influence of 40.7% on employee performance, making it the most significant factor. Motivation is an innate desire that propels people to accomplish the objectives they set for themselves at work. A high level of motivation can boost workers' morale, commitment, and work ethic. Managers must comprehend and use the elements that inspire workers, such as rewards for accomplishments, chances for professional growth, and suitable incentives.
However, with a total influence of 27.3%, work competency also has a noteworthy impact on employee performance. Job competencies are the set of abilities, attitudes, and knowledge required to succeed in a specific work. Workers with solid work abilities are typically better equipped to perform their jobs quickly and effectively. As a result, the organization's management must be dedicated to enhancing worker competency through development, training, and ongoing education.
With a coefficient of determination value of 68.1%, the analysis demonstrates that the influence of both job competence and motivation significantly influences variations in employee performance. Nonetheless, these two factors account for just about 31.9% of the variability in performance. External variables like the workplace, organizational policy, external economic situations, and internal employee considerations may also impact employee performance.
These results give the organization's management helpful information for creating plans and policies that enhance worker performance. Enhancing work competence and staff motivation can be a significant starting point. To improve effectiveness, businesses must also consider other aspects affecting employee performance.
The study highlights the significance of work motivation and competence as critical elements influencing employee performance in a marketing-related organization. Enterprises are expected to enhance their total performance, production, and efficiency by comprehending and controlling these aspects. To improve knowledge of the variables affecting worker performance and to pinpoint more targeted approaches to boosting competence and motivation at work, further study can be done.

Maatregelen tegen antidemocratische politieke partijen: de ‘escalatieladder’ ontleed

Er bestaat een arsenaal aan maatregelen die genomen kunnen worden tegen politieke partijen die antidemocratische opvattingen huldigen. Oplopend in sterkte vormen deze maatregelen gezamenlijk een escalatieladder. Het gaat dan om achtereenvolgens (1) het vervolgen van individuele partijleden, (2) het nemen van bestuurlijke maatregelen tegen partijen (subsidieontzegging en zendtijdontneming) en (3) het opleggen van een partijverbod. Deze maatregelen fungeren echter alleen als escalatieladder voor zover het gaat om het bestrijden van antidemocratische uitingen die strafbaar zijn gesteld. Men denke in dat kader aan opruiing (art. 131 Sr), groepsbelediging (art. 137c Sr) en aanzetten tot haat, geweld en discriminatie (art. 137d Sr). Antidemocratische uitingen die niet strafbaar zijn, zoals een oproep tot het afschaffen van vrije en eerlijke verkiezingen, kunnen in een uiterst geval alleen met het zwaarste middel in de kiem gesmoord worden: het partijverbod is daarvoor de enige mogelijkheid. Dat is een (extra) reden om de proportionaliteit van de verbodsregeling in de aangekondigde Wet op de politieke partijen te versterken.

Kamerdebat geeft geen reden voor staatsrechtelijke ontoelaatbaarheid van de motie van het lid Yeşilgöz-Zegerius c.s

In deze bijdrage wordt de staatsrechtelijke kritiek besproken die in de Tweede Kamer is geuit op de motie van het lid Yeşilgöz-Zegerius c.s., waarin een beroep gedaan werd op het kabinet en de Eerste Kamer om een pas op de plaats te maken met het wetsvoorstel voor de Spreidingswet. Ten eerste wordt besproken dat deze motie inbreuk zou maken op de zelfstandige positie van de Eerste Kamer. Dat is niet het geval omdat de motie juridisch niet bindend is voor de Eerste Kamer. Ten tweede wordt besproken dat de motie – ook al is ze niet juridisch bindend – toch een ontoelaatbare inmenging zou zijn in de wetsprocedure bij de Eerste Kamer. Dat is niet het geval gelet op het politieke primaat van de Tweede Kamer en op de overeenkomsten tussen deze motie en de novellepraktijk. Ten derde wordt besproken dat een demissionaire minister die tevens Kamerlid is vanwege de homogeniteitsregel geen recht zou hebben om een motie in te indienen die tot het kabinet is gericht. Ook dat is niet het geval, omdat de homogeniteitsregel slechts eist dat de minister zich neerlegt bij het besluit dat de ministerraad over de motie neemt, of aftreedt.

W.J.M. Voermans, Onze Constitutie. De geschreven en ongeschreven regels van het Nederlandse staatsbestel

Na meer dan 122 jaar is ‘Onze Constitutie’ weer terug van weggeweest. Dit keer niet van Alexander de Savornin Lohman, maar van de hand van Wim Voermans. De ambitie van het boekwerk is groots: het toegankelijk maken van het constitutionele recht voor iedereen, in het bijzonder voor de doorsnee Nederlandse burger.

Het boekwerk is een amalgaam van de constitutionele geschiedenis van Nederland, een inleiding tot het constitutionele recht, de Nederlandse staatsrechtwetenschap en Voermans’ kritiek daarop, in combinatie met grondwetscommentaar. Daarbij worden (onder meer) de belangrijkste historische momenten van constitutionele betekenis op bondige en handzame wijze beschreven. Ook wordt een indruk gegeven van de centrale vragen van de Nederlandse staatsrechtwetenschap. Dat is véél voor één boek en tegelijkertijd een witte raaf onder de handboeken over het constitutionele recht. In deze boekbespreking worden onderdelen van het boek besproken en enkele kanttekeningen geplaatst, onder meer over de ambitie om het constitutionele recht voor iedereen toegankelijk te maken: is dat gelukt?

Published: May 2024

The concept of ‘comparative advantage’ has always been at the heart of national economic development policy. It refers to the export goods that one country produces better than other countries and the trading of such goods for products that other countries produce best. Mongolia is a small, landlocked country, situated at great distances from the world’s major transport channels and seaports. It mainly exports agricultural and mining products to world markets and depends on imported goods for its domestic consumption. Landlocked countries are primarily affected not only by high transportation costs but also by low competitiveness in the global market.

Historically, Mongolia has benefited from the export of its raw agricultural materials, such as cashmere, wool and meat. However, rapid urbanisation, growing population needs and high import prices in recent years, especially during the COVID-19 pandemic, means the country must shift from its static comparative advantage of an economy to a dynamic one. Mongolia must pursue a trade policy aimed at creating value-added end products capable of meeting the demands of its domestic consumption and competing in the international arena based on development potentials and comparative advantages of the country. The objective of this paper is to illustrate how tariff optimisation could potentially be used to protect domestic industry, specifically focussing on the dairy production industry.

Published: May 2024

Background: A life-saving procedure is a blood transfusion, but there is often a shortage in blood supply due to various factors. Despite the enormous advancements in medical research, there is still no substitute for blood, making blood transfusions a crucial component of contemporary healthcare. The study aimed to evaluate the discard reasons for blood components, particularly Fresh Frozen Plasma, Platelet Concentration, and Red Cell Concentration and to suggest possible strategies to reduce wastage. Methods: The Retrospective analysis of discarded blood components was carried out from July, 1st 2023 to December 31st 2023 in the blood bank of Parul Sevashram. Data was collected using a discard register and computer data of discard available in blood bank and was analysed in SPSS software version 26.0 and Microsoft Excel. The wastage rate was calculated with a percentage of total number of units wastage against the total number of collections. Results: A total of 4990 blood component were prepared out of which 706 blood component was discarded. The total discard ratio of the study was 14.14%. Total replacement donors were 83.91% and 16.31% were voluntary donations. The discard rate for PC, RCC, and FFP was 86.30%, 6.82%, and 2.01%. HbsAg was the most common reason for the discard due to seropositivity of TTIs. Conclusion: The Most common component discarded was platelet and the reason for discard was the date of expiry due to non-utilization. Seropositivity was the reason for discarding red cell concentration and leakage was the most common reason for fresh frozen plasma. The wastage can be reduced by implementing proper strategies such as FIFO policy, avoiding Mega camps, proper staff training and wastage reduced protocol.

Este artigo tem por objetivo compreender a construção e estrutura do conhecimento em comunidades coletoras de Castanha-do-Brasil localizadas em duas Unidades de Conservação do tipo Florestas Nacionais (FLONA), FLONA Mapiá-Inauiní e FLONA Purus, no estado do Amazonas, Brasil. Adotou-se uma abordagem exploratória, mediante o emprego de procedimentos qualitativos e quantitativos nas análises. Os resultados indicam que os conhecimentos tácitos dos coletores de Castanha-do-Pará influenciam na forma como eles percebem os problemas e as oportunidades de seu ambiente de atuação e determinam, também, processos de socialização do conhecimento. O conhecimento tácito os habilita no “como fazer” as atividades de coleta. Porém nem todos sabem a razão pelo qual executam determinadas atividades de uma determinada maneira. O estudo demonstrou que não estão acontecendo processos de construção de saberes relevantes a partir de interações comunitárias, nem do compartilhamento de saberes técnico-cientifico exógenos. A estruturação desse processo evidenciou os possíveis níveis de intervenção que o Estado poderia realizar ao contatar e instruir esses grupos de coletores extrativistas quanto à sua atividade laboral.

Devido ao grande número de fábricas no Polo Industrial de Manaus e o aumento da concorrência comercial, as empresas estão em busca de minimizar seus custos de produção, otimizar processo e diminuir o tempo de resposta para possíveis alterações do mercado. Dentre os métodos utilizados para alcançar esse objetivo, muitas empresas utilizam o método de Lean Manufactoring (Produção Enxuta) que tem como meta diminuir todo desperdício dentro dos seus processos organizacionais.  Nesse contexto, o estudo de caso aplicado nesta empresa de fabricação de ar-condicionado se justifica devido a necessidade da redução de custo no processo de aquisição da matéria prima suporte fixador do IDU, pois antes a peça era importada e a matéria prima era metal o que deixava seus valores menos competitivos. Após estudos notou-se ser viável a alteração desta peça para matéria prima plástica podendo a sua fabricação ser nacionalizada e dentro da própria empresa. Após os estudos, todas as peças foram aprovadas nos testes de qualidade e engenharia e no final calculou-se uma redução de custo de 50% na aquisição da matéria prima além de maior controle interno de demanda.

O estudo do crescimento controlado de filmes finos tem despertado um considerável interesse para uma ampla gama de aplicações, principalmente no ramo de dispositivos eletrônicos. Moléculas que podem levar à otimização das propriedades eletrônicas e óticas quando dispostas na forma de filmes finos vem sendo estudadas, como é o caso das ftalocianinas metálicas. Por serem compostos macrocíclicos planares têm alta estabilidade térmica e química, ainda possuem intensa coloração verde ou azul. Os filmes finos se enquadram na categoria de materiais bidimensionais, podendo ser obtidos por diversas técnicas já difundidas na literatura. Porém, as ftalocianinas apresentam baixa solubilidade em solventes orgânicos e água, se não substituídas nos anéis. Foi então realizado um estudo prévio da solubilidade dos compostos usados neste trabalho, ftalocianina de gadolínio na forma mono (GdPc), em diferentes solventes: dimetilformamida (DMF), dimetilsulfóxido (DMSO), tetraidrofurano (THF), clorofórmio (CHCl3) e acetona. Para deposição dos filmes de ambos os compostos, preparados sobre substratos de vidro e vidro recoberto com óxido de estanho dopado com flúor (FTO), foi utilizada a técnica de aerografia. Os solventes para o preparo das soluções foram aqueles onde as ftalocianinas apresentaram melhor solubilidade, DMF e CHCl3 para a GdPc. Soluções das ftalocianinas nos solventes DMF, DMSO, THF, CHCl3 e acetona foram caracterizadas por espectroscopia de absorção na região do ultravioleta-visível (UV-Vis), mostrando a influência do solvente nas bandas características das ftalocianinas, B e Q. A alteração nas características dessas bandas indica diferentes arranjos das moléculas, formas chamadas a e b, e apresentaram diferentes arranjos para os solventes utilizados. Os filmes formados foram analisados antes e após annealing para verificar a morfologia e as possíveis mudanças ocorridas com o annealing, como alteração da fase a para a fase b. Essas análises foram realizadas por UV-Vis. Após annealing, as alterações observadas sugerem uma reordenação das moléculas para a GdPc em acetona quando o substrato é vidro. Os demais filmes possivelmente não completaram esta mudança de fase por falta de material depositado sobre os substratos.

Results of the experimental studies of the force resistance and deformation of compressed elements from porous concrete of 1200-1600 kg/m3 density of various structural modifications (fine grain and micro grain) are presented. On the basis of research date, mechanical properties are complexly characterized; a criterion number of strength and deformation characteristics of porous concretes with due regard for the influence of longtime processes due to concrete hardening and external force factors is proposed. On the basis of data on the long-term resistance of porous concrete and change in its strength in time, calculation characteristics and coefficients of operation conditions of porous concrete are established for calculation and design of structures. It is shown that according to structural indicators, porous concretes meet normative requirements and occupy the intermediate place between cellular and light concretes of equal strength with porous fillers.
