Migrant Children in Southern Europe
Authors: Bañon Castellón Lola
Published: June 2024

One of the growing phenomena in southern European migration is the increasing number of children travelling alone. Their stigmatisation is partly due to the discourse disseminated by some media and social networks. This study analyses the treatment of unaccompanied foreign children and adolescents, often labelled with the acronym MENA, by Spanish television news programmes. The sample of this study covers productions broadcast on the first screen and reduplicated in the digital sphere. It is concluded that, in general, there has been an evolution in professional awareness of the media treatment of their image, this being more evident in public television. However, there is a negative assignment of meaning to foreign minors due to the arguments put forward by extreme right-wing parties, which have gained presence in both traditional and digital media.

Authors: Dhungana Bharat Ram , Kunwar Subash , Ojha Deepak , Lamichane Keshav , Acharya Sujana
Published: June 2024

The paper examines the factors affecting investors’ decisions on initial public offerings with reference to Pokhara, Nepal. The five predictive variables—management quality, company goodwill, company performance, firm’s industry, and market information— have been included in the study. The primary data was collected from a field survey using a structured questionnaire from 223 respondents. Descriptive (demographic and perception-related information) and inferential statistics (correlation) were used for analysis. We find that company goodwill, company performance, firm’s industry, management quality, and market information affect investors’ IPO decisions. The legitimacy of the company, key shareholders profile, founder and CEO of the company, prestige of the board members, company’s financial position and historical background, return on equity, earnings per share, capital gains, and existing market share affect investors’ IPO decisions. Most investors select IPOs of finance, microfinance, and insurance companies as primary investment areas. These findings provide important information for companies and regulators in their assessment of investor demand and disclosure of information.
Optimal Selection of Cities of Energy Outlets in Developing Countries: An Application of Fuzzy Set Theory to Sri Lankan Solar Industry
Authors: Perera D.P. , Kumara U.A. , Yapa S.T.W.S.
Published: June 2024

The concept of benefit gains is inherently fuzzy in nature. Hence, this study seeks to propose a logic-based innovative formalism that helps in effective decision-making in dynamic, imprecise, inconclusive, and volatile business environments underpinned by technology. Such an attempt, deriving from Fuzzy Set Theory, is needed as we apply this model to the financial gain-based optimal selection of cities to establish business outlets with reference to the solar power generation industry. Modelling the perceptions of domain experts is an integral part of the fuzzy approach. However, these linguistic inputs of experts become intelligible only when quantified through similarity methods and fuzzy tolerance relations comparing the yielded values against proximity ratios. The acquisition of expert knowledge was made by interviewing five economic and finance-proficient individuals in Sri Lanka with tacit know-how. The fuzzy inference was used to transform qualitative words and quantitative data into objective crisp values. The study was operationalized through computing with words, cosine amplitude transformation, and Bellman Zadeh approach. Both the Fuzzy Inference System and Bellman Zadeh’s approach were amalgamated for data analysis. In deriving the membership values, two business goals of monetary nature were formulated. The findings reveal that the country’s politics, business owners’ financial solvency, operational maintenance, and business foresight are the constraints that impact financial gains and accomplishing defined goals at variance. Among these, politics and business foresight are external factors, while solvency and operational maintenance are internalised.

Authors: De Silva L.N. , Dhammika K.A.S
Published: June 2024

With the Generation Z taking over the workforce of Sri Lanka, as more and more of these individuals entering the job market and moving up the corporate ladder, it seems for the workplace to be prepared to not only welcoming but retaining these employees in the long run. The age-old Human Resource conundrum of dysfunctional employee turnover comes to mind in the light of this new generation. This study was carried out to find the factors affecting to the turnover of the Gen Z employees in Sri Lanka. A sample of 76 non-technical employees was drawn from the financial sector by using stratified random sampling method with 72% response rate. Data was collected by administering a questionnaire measuring the variables of the study. The questionnaire was distributed online to the respondents. It was found that life expectations have significant impact on the level of turnover intention of the Gen Z employees. However, the study found no evidence on the possible impact of job expectations on turnover intention. As expected, the Employee Value Proposition (EVP) recorded a significant impact on employee turnover intention. The findings of this study bear some theoretical and practical implications and are bounded with certain limitations. Further studies are recommended with the aim rectifying the limitations.

Authors: Udurawana Y.M.W.G.P.K.
Published: June 2024

World tourism has significantly contributed to destinations generating more social, economic and environmental benefits. Therefore, all tourist destinations have identified sustainability as their main goal of tourism. There are plenty of research to discuss the effect of experiential marketing, tourists’ satisfaction, destination image and destination loyalty than measuring these variables’ effect on sustainable tourism. In the Sri Lankan context, though Sri Lanka has many world heritage destinations to facilitate sustainable tourism, it has only a few cultural attractions. Further, there was no research to address the experiential marketing effect on sustainable tourism through image, satisfaction and loyalty. This gap has been addressed through this research with three mediating variables referenced to cultural destinations in Sri Lanka. To collect data for the study 513 tourists representing all tourists who visited Sri Lanka in 2019 conveniently interviewed. The data were analyzed through the SPSS Amos software and was able to achieve all the research objectives and answer all the research questions. The findings of the study include adaptable strategies for the attention of all the destination-marketing authorities in Sri Lanka, which may help to facilitate experiential marketing for sustainable tourism through destination image, tourists’ satisfaction, and destination loyalty for cultural destinations in Sri Lanka.
A Review of the Modern Methodological Approaches to Tracking Elephant Intrusion in Sri Lanka
Authors: Nijamir K. , Kuruppuarachchi K.A.J.M. , Madurapperuma B.D.
Published: June 2024

This review aims to address the prevailing issues of elephant intrusion and the subsequent Human Elephant Conflict (HEC) in Sri Lanka, particularly in villages where the seasonal concentration of elephants can be observed in agricultural and surrounding wetlands. The episodic gatherings of elephants in these specific areas are a serious concern due to the lack of integrated control measures. The incidents of elephant gatherings are increasing in rural villages, especially during the off-season of paddy cultivation or nearing the harvesting period, as well as during the blooming times of fresh grass in the riverbeds. These interactions with people along their range lead to the onset of HEC scenarios. If these elephant gatherings are left without solutions, it could pose a significant threat to the affected areas, settlements, and economic values, making them highly vulnerable. Therefore, this paper suggests a holistic approach that integrates modern techniques with a literature review to explore and assess existing methods and identify viable ones to control elephant intrusion and mitigate the impacts on the affected areas and Sri Lanka as a whole.
The challenges of writing the history of localities that were under colonial rule in the early phase of European expansion: An investigation into writing the history of Negombo (Sri Lanka) in the sixteenth and early seventeenth centuries
Authors: De Silva Chandra R.
Published: June 2024

Local history has been conventionally defined as a chronicle of a limited geographical area. The study of local history can have positive outcomes including reconstructing our ancestor’s everyday lives and providing opportunities for students to develop investigative research skills, develop linkages with locals and to also motivate students to improve their basic skills of reading, writing and critical thinking. Unlike in the West, however, where local historians use old records of their locality, local historians of lands colonized by Westerners have problems finding source material. For example, in Sri Lanka, the Portuguese occupying the southwest lowlands destroyed Buddhist and Hindu temples which often contained local records. They tried to replace the temples with Roman Catholic churches, but these records also seem to have been lost when they were also mostly abandoned or destroyed under Calvinist Dutch rule. This article, based on an examination of Portuguese archival material relating to an area on the western coast of Sri Lanka during the sixteenth and seventeenth centuries, argues that, despite the gaps created by the loss of local records, data from colonial archival sources when used with a critical eye, can be used to give us some insights on economic practices within localities that were colonized. They also provide at least a glimpse of both the changes and the continuities in the life of the people, as well as the economic burdens imposed on them by the state during colonial rule and the social changes that resulted from colonial policies.

Authors: Piazza Isabelle , Barcella Bruno , Cascio Michela , Group CoSMEU
Published: June 2024

At the end of October 2023, CoSMEU (Italian Society of Emergency Medicine Residents) conducted an electronic survey among the Italian Emergency Medicine (EM) residents. Technical skills, lecture programs, research, and types of employment have been investigated. 421 (21.5.%) residents from all the 34 Italian EM schools responded. Great heterogeneity of training and the lack of opportunities in research about EM topics are reported. The importance of research in EM was recognized by half of those surveyed, but only one-third are actively engaged in the EM scientific community. While one-third of EM residents have accepted a job contract, nearly all of them are against contracts with Calabria Decree from the 2nd year of residency. The ideal workplace is a combination of in-hospital and pre-hospital settings, and almost all of the EM residents believe that the most frightening part of being an EM doctor is the hard-working condition.

Published: June 2024

Short urethras make urinary tract infections (UTIs) common in women. Therefore, bacteria can enter the bladder more easily. This research aimed to determine if the neutrophil-to-lymphocyte ratio (NLR) can be used as a biomarker in UTI patients and compare C-reactive protein (CRP) and NLR to identify which is more effective in diagnosing UTI patients. This study examined urine culture, NLR, and CRP values in blood from 101 Thumbay University Hospital patients with UTI. Control group NLR and CRP values of 100 participants were also examined. NLR mean for UTI patients was 6.9881. The NLR mean for UTI-free participants was 3.0839. Comparison of NLR values between UTI patients and non-UTI patients showed significant results (P=<0.001). Thus, patients with UTI had significantly higher NLR results than those without UTI, indicating a strong correlation between UTI and higher NLR values. Our results showed that UTI patients had higher NLR and CRP values than healthy controls. In patients with UTI, clinical assessment of symptoms and complaints should be done first, followed by NLR and CRP as inflammatory markers.
Experimental and Numerical Investigations of a Dual-Fuel
Hydrogen–Kerosene Engine for Sustainable General Aviation
Authors: Reitmayr Christian , Wiesmann Frederik , Gotthard Thomas , Hofmann Peter
Published: June 2024

Reducing CO2 emissions is an increasingly important issue. In
aviation, approaches such as e-propulsion only represent a solution for special
applications due to the low energy density of batteries. Because of the low-cost
and robust design of combustion engines, this concept is still the most suitable
for general aviation. For defossilization, besides e-fuels and bio-fuels, which
represent the so-called sustainable aviation fuels (SAF), hydrogen can serve as
a promising energy carrier for CO2 reduction. For this purpose, the
combustion process of a dual-fuel hydrogen–kerosene (Jet A-1) engine was
developed and investigated for use in small aircrafts. This study explores the
influence of hydrogen addition on combustion parameters, emissions, and
efficiency.

An advantage of this special design as dual-fuel engine (hydrogen and kerosene)
is the possibility of redundancy operation in the event of a H2 fuel
system failure as well as full operational capability of the aircraft in the
event of hydrogen supply difficulties at various airports. Besides test bench
investigations, 3D CFD simulations were performed to optimize hydrogen injector
position, ensure backfire-free operation, and improve mixture formation. In
addition to a low load and high load point, a high-altitude point was
investigated based on real flight data.

The maximum achievable hydrogen energy shares, limited by abnormal combustion,
and the respective CO2 reductions are shown. Furthermore, the
influence of the hydrogen mass distribution in the inlet ports was investigated
to achieve an advantage in the homogenization of the hydrogen–air mixture.
Finally, the efficiency losses in hydrogen dual-fuel mode compared to base
kerosene operation are shown in a detailed analysis.
Motor Vehicle Technology-Progress and Harmony
Authors: Hiroshi Takahashi
Published: June 2024

The history of the automobile's progress is one of harmony with society. Automobiles have progressed by applying to the maximum degree the available technologies of each era and seeking harmony between social needs, the needs of consumers and the state of road system development. The most critical and lasting issues in the automobile world will continue to be safety, the wise use of natural resources and protection of the environment. While it is necessary for automobiles to make their own contribution to the solution of these issues, it is also vital that automobiles be developed as a part of a total system in harmony with public investment, such as road facilities. In particular, it is necessary that a radio communications link between automobiles and a traffic control network be introduced to enable driving that is safe, efficient and in good harmony with the environment. In order to overcome these problems, it is necessary to actively engage in information and technology exchanges that transcend national boundaries and the bounds of technical specialties, and at the same time introduce a wide range of advanced technologies.

The Visual Artists Rights Act in augmented and virtual realities
Authors: Windsor Casey
Published: June 2024

The expansion of augmented reality (AR) and virtual reality (VR) has brought to light the gaps in U.S. law regarding moral rights protections in the digital age. The U.S. offers limited protection of moral rights under the Visual Artists Rights Act (VARA). Although protections are limited, AR and VR programs could violate artists’ moral rights under VARA by modifying existing art used in their programs and by not giving an artist’s work attribution. Another question that has emerged is whether VARA could protect digitally produced art. VARA is a limiting statute and narrowly defined visual art to exclude most digitally produced art. Therefore, in order for digital art to be protected under VARA, the U.S. needs to modernize the statute to fit into a digital world.

The Role of Digitalization in EAEU–ASEAN Dialogue
Authors: Fedorov N. V.
Published: June 2024

The article examines the role of digitalization in EAEU–ASEAN dialogue. The EAEU tries to develop cooperation with Southeast Asia, as for separate states, so with ASEAN. The sides have made some significant steps for strengthening of their interaction for the last years. However, the EAEU and ASEAN still have no free trade agreement or other formal document for economic cooperation. One of reasons for that seems to be relatively low level of trade ties and integration between EAEU and ASEAN member-states. EAEU and ASEAN officials make focus at their dialogue for facilitation and development of their economic cooperation. The digitalization takes important position in this interaction. The EAEU and ASEAN pay special attention to digitalization in their programs of development. The EAEU and ASEAN representatives accented the importance of digitalization as an instrument of cooperation (for example, in the relation of customs regulations and electronic trade). Digitalization issues have been included into agenda of different events with participation of the EAEU and ASEAN (for instance, Petersburg International Economic Forums). Representatives of the EAEU and ASEAN, separate member-states and business-communities discussed digitalization. Although the digitalization of EAEU–ASEAN cooperation makes the first steps, but, at the same time, we can see some practical results (on the example of activities of the Russia-Singapore Business Council and Singaporean company vCargoCloud). The digitalization in the framework of EAEU–ASEAN interaction has prospects for further development and can create conditions for strengthening ties between the EAEU and ASEAN.

Oil and global politics after 24 February 2022
Authors: Stoiian Tetiana
Published: June 2024

A study of the impact of oil on global politics at this time is necessary to understand the relationship between energy security, geopolitical conflicts, and economic relations, which could substantially affect the future of the global energy landscape and international relations. The purpose of this study was to analyse the impact of the oil market on geopolitical relations and develop strategies to ensure energy security and stability in the international arena. The meth- ods employed include the analytical method, classification method, functional method, statistical method, and synthesis method. The study found that the rise in oil and other energy prices after the outbreak of geopolitical conflicts led to a considerable increase in economic pressure on importing countries. It was emphasised that the development of alterna- tive energy sources has become a vital strategic step to reduce dependence on oil. For instance, expanding the use of solar and wind power can help to balance the energy mix and reduce risks from geopolitical turbulence. The study analysed the possibilities of international cooperation in the energy sector to ensure energy security and stability in the global market. It was found that synergy between countries can help reduce the impact of geopolitical conflicts on the energy market and ensure sustainable energy supplies. It was established that the transition to alternative energy sources and the de- velopment of effective energy security strategies are key factors in supporting the sustainable development of national economies in a changing geopolitical environment. The conclusion is that there is a need to intensify efforts to develop and implement a comprehensive approach to energy regulation to ensure energy stability and maintain international peace and security. The authorities, business, and other stakeholders can use the findings of this study to make strategic decisions in the field of energy and global economic relations

Authors: Souza dos Reis Hélio , Bomfim Luciano Sérgio Ventin , Oliveira Juliana Gabriela Alves de , Fraga Araújo Jairton , Silva Marcos Antônio Vanderlei
Published: June 2024

Na região do Submédio São Francisco, as agriculturas contemporâneas têm ganhado destaque na produção de alimentos e na geração de emprego e renda para muitas famílias, especialmente a agricultura familiar, orgânica e, sobretudo, a agricultura irrigada. Embora essas agriculturas tragam os benefícios mencionados anteriormente, algumas ainda apresentam impactos negativos no ecossistema. Nesta perspectiva, por meio de uma revisão bibliográfica sistemática, buscou-se identificar e avaliar a relação entre essas agriculturas e a (in)sustentabilidade em municípios desta região. Para isso, utilizou-se uma abordagem exploratória-descritiva e qualitativa, sobre como as agriculturas contemporâneas estão impactando as dimensões social, econômica e ambiental. Foram selecionados trabalhos publicados entre os anos de 2013 e 2022 nas bases de dados Scientific Electronic Library Online (SciELO), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) e Google Scholar. Além disso, foram incluídas pesquisas de natureza empírica e teórica publicadas em língua portuguesa e inglesa. Esta análise revelou que as agriculturas promoveram mudanças significativas na região estudada, porém algumas delas de maneira insustentável. Portanto, é necessário conscientizar tanto dos produtores quanto a sociedade sobre a importância da conservação e preservação do meio ambiente, além de investir em medidas que promovam uma agricultura mais sustentável por parte do Estado.

Neste ensaio mapeamos alguns ditos, e possíveis não-ditos em aulas de Anatomia Humana, utilizando como pontos de ancoragem para esta discussão (in)certas estruturas que compõem os corpos humanos. As análises foram desenvolvidas à luz do pensamento de Paul Beatriz Preciado, sobretudo na obra intitulada Manifesto Contrassexual (2014). Nesse percurso teórico, por intermédio das seções “Entre Digerir e Gozar” e “Por que a mão não é considerada um órgão sexual?”, foram apontadas linhas de fuga para a operacionalização de outras práticas pedagógicas, mais sensíveis, acolhedoras e problematizadoras, no ensino desse componente curricular.

Published: June 2024

O artigo contém uma análise comparativa generalizada sobre a extracção e exportação da produção de matérias-primas minerais na República do Cazaquistão. No artigo são analisadas as condições, a produção e o consumo de ouro, cobre e metais no mundo. Entre os países de interesse na Ásia Central, pode-se mencionar o Cazaquistão, com a sua Kazakhmys, a maior produtora de cobre. A China, onde, de acordo com o código de novas minas chinesas, as empresas estrangeiras de mineração podem adquirir uma participação de 100% na exploração de diamantes, mas não concessões, o que poderia levar a aumento da atividade de exploração estrangeira. O ramo mínero-metalúrgico é um dos mais importantes factores de desenvolvimento económico da República do Cazaquistão. No entanto, a progressão neste campo da economia também previu que a segurança econômica, potencial de exportação, oportunidades de desenvolvimento da República do Cazaquistão em comparação com a Ásia e do mundo. O artigo representa interesse prático para os alunos, mestres, doutores e especialistas do ramo.

Neste artigo explora-se o conceito de planeamento estratégico num contexto específico, designadamente, o ensino superior português. Este artigo pretende, assim, contribuir para a sensibilização dos diversos actores que têm uma intervenção directa ou indirecta neste sector para necessidade de planear e pensar estrategicamente o ensino superior. Para isso, vão-se buscar à indústria diversos contributos que permitam desenhar um modelo conceptual de planeamento estratégico para o sector que possa reunir o consenso daqueles que o irão aplicar. O modelo referido integra, na medida do possível, os contributos das diversas escolas de formulação da estratégia, designadamente, prescritivas e descritivas e deve estar adaptado às especificidades do sector em estudo.
Knowledge of Complementary and Integrative Health among Collegiate Athletic Trainers
Authors: Flaig Amanda , Rivera Matthew J. , Eberman Lindsey
Published: June 2024

Purpose: Complementary and integrative health (CIH) interventions are non-mainstream modalities used to complement traditional care and are used by athletic trainers. Interventions encompassing CIH can help provide holistic care that is patient-centered. However, there is no previous research on the attitudes and use of CIH in everyday clinical care. The purpose of this project is to investigate athletic trainers’ use and attitudes towards CIH interventions. Methods: A cross-sectional, web-based survey including demographics, CIH integration, and the Complementary Health Belief Questionnaire (CHBQ) was sent out to a random sample of athletic trainers. Measures of central tendency were calculated to characterize the behaviors and use of CIH by athletic trainers. The scores on the CHBQ were averaged and an independent t-test was used to compare the CHBQ scores between athletic trainers who use CIH and those who do not. Results: The average total score for the CHBQ is 43.41±4.26, indicating generally positive beliefs and attitudes towards CIH interventions. There were no statistical differences in CHBQ scores between athletic trainers who use CIH interventions and those who do not, indicating both groups have positive attitudes towards CIH intervention. Further, the most common interventions used by athletic trainers were massage, yoga, and chiropractic care. Conclusion: Many collegiate athletic trainers incorporate CIH interventions into their practice and tend to have positive attitudes towards CIH. In order to treat the whole patient, athletic trainers should consider incorporating CIH interventions into their practice in order to assist in positive patient reported outcomes.

Modern food packaging no longer only plays a passive role in protecting and selling food, but actively changes the state of the packaged food in order to extend its shelf life. From that aspect, packaging based on cellulose, TEMPO-oxidized cellulose nanofibrils (TOCN), and chitosan, has great application potential. In this work, ultra-thin films (thickness below 100 nm) based on cellulose, TOCN, and chitosan were made to serve as a general model for packaging based on cellulose, TOCN, and chitosan. Using a quartz crystal microbalance with dissipation (QCM-D), it was investigated how TOCN coating affects the water absorbance capacity of cellulose-based ultra-thin films, as well as at which pH values greater chitosan adsorption occurs on ultra-thin films based on cellulose and TOCN. The bio-activity of the multilayered thin films was evaluated in vitro against Staphylococcus aureus and Escherichia coli. The multifunctionality comprising high water absorbance capacity and antimicrobial activity, recommend such polysaccharide-based thin films for food packaging applications

he pulp washing line is one of the key areas of innovation, improvement and investment, which ensures the technical efficiency of the entire technological process of pulp production (washing efficiency, reduction of alkali loss, increases the quality of produced and washed pulp, etc.), improves environmental protection, improves the degree of regeneration chemicals, greater utilization of heat, and ultimately affects the productivity, cost prices and profitability of the pulp mill. In order to achieve these goals in pulp production at Natron-Hayat, installed a DPA press last year as the final stage of washing unbleached softwood pulp. Significant results were achieved in reducing the loss of alkali and reducing the consumption of hot water, steam, and anti-foaming agents. In addition to these savings, the number of downtimes has been reduced due to washing the equiment on the paper machine.
