Published: February 2024

Markhor (Capra Falconeri), is notably endangered ungulate native to the northern mountains of Chitral, Pakistan, specifically within the Chitral Goal National Park and Tooshe Shaha Conservancy Area (TSC), is facing a serious threat from gastrointestinal (GI) parasites. These parasites adversely affect the health of Markhor, resulting in pathological and immunological degeneration. The conservation plan for Markhor is further complicated by climate change, introducing challenges, particularly in terms of hunting trophies. This study, conducted from October 2022 to May 2023. The primary goal was to evaluate the prevalence and distribution of gastrointestinal parasites in Markhor within the Chitral national parks. A total of n=200 fecal samples were processed and analyzed using flotation, sedimentation techniques, and the McMaster slide method to identify the prevailing parasites in these samples, 64% tested positive for various helminthes eggs and larvae. The prevalence rates for specific helminth species were identified as follows: strongyles 20%, trichostrongyles 14.5%, ostertagia 11%, haemonchus 8.5%, and trichuris 10%. Notably, 44% of positive animals exhibited co-infections. The collected fecal samples detected no eggs or larvae of trematodes (flukes) or cestodes (tapeworms). An overall protozoan infection proportion of 47.5% indicated that nearly half of the fecal samples were positive for protozoan parasites. Eimeria was present in 31.5% of the samples, while Entamoebiosis caused by Entamoeba was found in 15.5%. Gastrointestinal parasites were observed to be widely distributed among Markhor, posing a significant burden of various parasites and increasing the risks of morbidity and mortality. This research highlights the health challenges resulting from parasitic infections in the Markhor (Capra Falconeri) population as substantial contributors to poor health outcomes. It calls for collaborative efforts among stakeholders to address these challenges and ensure the long-term survival of Markhor conservation. Furthermore, it highlights the importance of preserving the natural habitat of Markhor populations in the northern Chitral region to prevent infections and habitat degradation.
Pensamiento económico de Fray Pedro de Aragón, OESA
Authors: Somavilla Dr. Enrique
Published: February 2024

Fray Pedro de Aragón, OESA, es uno de los teólogos moralistas economistas del siglo XVI. La época del Renacimiento y el Humanismo fue un período de transición entre la preponderancia de los esquemas culturales establecidos por la Iglesia, en la Edad Media, donde el carácter eclesiástico lo invadía todo a la Edad Moderna donde va a imperar los criterios seculares como eje de la cultura, aunque permanezca la Escolástica denominada segunda o tardía. Por eso será muy determinante las líneas de pensamiento como las de fray Pedro de Aragón, OESA. Con él, aparece una teoría económica independiente, en el sentido que hoy le damos; esto supone que se pueda decir que exista en su estudio, un orden económico, desde la visión ética. Dicho orden será preciso para procurar las normas morales con conocimiento de causa. Para ellos, la economía estará subordinada a la moral. Por eso, estos moralistas-economistas serán sus primeros representantes y estudiaron con carácter científico los hechos y dificultades económicas surgidas tras el descubrimiento del Nuevo Mundo.

What justice? The scope for public participation in the European Union Just Transition
Authors: Armeni Chiara
Published: February 2024

The climate crisis shapes and is shaped by inequalities. This nexus urges us to consider the justice questions arising from tackling the crisis. Against this background, the notion of “just transition” is gaining ground. Its main idea is that the socio-economic burden of climate measures requires corrective mechanisms to ensure that the climate transition is just. However, what “justice” means in this context and its consequences for legally protected rights to participate in decisions about the transition deserve more scrutiny. This article addresses these questions by exploring the conceptual understanding of justice and the space for citizens’ participation within the EU Just Transition policy and legal framework. It argues that the EU Just Transition is merely built on a distributive understanding of justice and that this constrains participation. But procedures cannot be ignored if the EU is seriously committed to a just transition. The article suggests that a closer alignment with participatory environmental rights under the Aarhus Convention could strengthen the procedural justice credentials of the EU Just Transition framework while upholding its distributive approach.

The Emergence Of EU Withdrawal Law
Authors: Wessel Ramses A. , Polak Polly R.
Published: February 2024

“EU withdrawal law” has become a sub-field ofEUlaw.Nowthat the dust of the first withdrawal of a Member State from the EU is slowly settling, one can take a step back and analyse “withdrawal law” in a more comprehensive fashion. Its main characteristics reveal the extensive, and largely exclusive, role of the EU as such in the process of negotiating and concluding both a withdrawal agreement and a future trade deal. This reflects the procedure, which may not have been given too much attention when it was included in theTreaty, but which formed the basis for extensive subsequent institutional and scholarly interpretation. EU withdrawal law reveals not only that Member States wishing to leave the Union have to follow strict rules and procedures, but also that these rules and procedures partly remain relevant after the actual withdrawal.

Authors: Bai Jiaying
Published: February 2024

Task-based Language Teaching (TBLT), emerging in the 1980s, is a new type of language teaching approach emphasizes ‘learning by doing’, focusing on the student’s main status, and achieving the teaching goal through the assistance of teachers. In the first part of this article, brief introductions of TBLT, tasks and the teaching principles are respectively given. In the second part, guided by three of the teaching principles of TBLT proposed by Nunan, including learning to communicate through interaction in the target language, focusing on the learning process and attaching importance to the learner’s own personal experiences, a reading teaching plan for the grade nine students is presented. Learners are inspired to discover rules by experiencing language, and use the target language to communicate and solve problems in the process. Under the guidance of TBLT in this reading class on tea culture, we can find that during the most of the time in class, students can not only perform communication actively about tea topic but also perceive more related linguistic knowledge and consolidate reading skills in the process of completing a series of tasks independently or in cooperative ways. Thereby, the student-centered principle can be realized.

Realizing the Emotional Crossing from “Selfishness” to “Goodness”: Realistic Reflections on Hume’S Theory of Sympathy
Authors: Ling Zhehong , Ye Hui
Published: February 2024

The essence of “sympathy” in Hume’s perspective is an emotional transmission mechanism. The exertion of its utility is affected by the relations of resemblance, contiguity and causation. In depth, this emotional transmission mechanism is composed of four links: “self-love” as the origin, “standing by” as the position, “self-reflection” as the impetus, and “goodness” as the emotional direction. Smooth and successful transmission of these four links will help to achieve the emotional crossing from “selfishness” to “goodness”. Under the enlightenment of Hume’s theory, a man needs to look on independently and objectively on the basis of natural conscience, in order to be a qualified sympathizer. At the social level, it is required to build a sympathy environment with impartiality and objectivity, which needs to strengthen sympathy education and to improve the moral reward and punishment mechanism, so as to provide sufficient internal and external conditions for the crossing from “selfishness” to “goodness”.

Authors: Liu Zonghui , Yang Rundai , Qin Liheng , Qian Zhonghua
Published: February 2024

Low concentration coal bed gas used for power generation is a better treatment scheme at present, which solves the problem of environmental pollution caused by the direct emptying of coal bed gas. Coal bed methane is a methyl alkyl fuel, and slow combustion rate will cause abnormal combustion phenomena such as large combustion cycle changes. The initial ambient gas concentration has a great influence on the development and propagation of the flame. In this paper, a constant volume bomb model is established to change the excess air coefficient of methane air premix in the initial constant volume bomb, and the change law of combustion heat release is analyzed. The results show that when hydrogen participates in the combustion stage, the combustion rate increases with the increase of excess air coefficient. When hydrogen is burned out, the combustion rate decreases with the increase of excess air coefficient.

Authors: Guo Yuefan
Published: February 2024

Lucid waters and green mountains are gold and silver mountains, and employment is the foundation of people's livelihood. Protecting the environment and promoting the employment are the important subjects of China's economic and social development. Based on the theoretical and empirical evidence, this paper finds through the provincial panel data from 2010 to 2019 that environmental regulation generally promotes employment by affecting GDP, but environmental regulation in northeast China has a negative effect on employment. Therefore, China should find the balance between the intensity of environmental regulation and economic growth, so as to protect the environment and improve people's livelihood.

Published: February 2024

Hydroxyapatite, with excellent biocompatibility, biological activity, and biological affinity, is the main inorganic component of human bones and teeth. It can promote bone tissue regeneration and has important applications in bone tissue engineering fields such as bone defect repair and bone replacement. In this study, calcium acetate solution and diammonium dihydrogen phosphate solution had been mixed to prepare calcium phosphate through aqueous precipitation reaction. The testing results of scanning electron microscopy and X-ray diffraction show that the morphology of the product can be controlled by changing the pH, the temperature, and the method of adding reactant solution dropwise. When the temperature of the reaction system is 20℃, plate-like calcium hydrogen phosphate is mainly obtained; block-like hydroxyapatite is obtained when the temperature rised to 40℃; and needle shaped hydroxyapatite is obtained at 60℃. The length and diameter of two-dimensional hydroxyapatite crystals become smaller when the temperature and the pH value of the reaction system increase.
An Empirical Study on the Short-term Impact of the Environmental Protection Fee-to-Tax Reform on Corporate Investment Efficiency
Authors: Zou Jiaxing
Published: February 2024

This paper uses non-financial A-share listed companies in China from 2010 to 2020 as research samples, utilizing the quasi-natural experiment conducted through the implementation of the "Environmental Protection Tax Law". The study investigates the short-term impact of the environmental protection fee-to-tax policy on corporate investment efficiency using a generalized difference-in-differences approach. The results indicate that the implementation of the environmental protection fee-to-tax policy significantly suppresses corporate investment efficiency in the short term and increases firms' inefficient investment. Furthermore, it is found that the policy exacerbates the problem of corporate overinvestment, whereas its impact on underinvestment is not significant. After conducting robustness tests by substituting the dependent variables, the conclusion remains valid. Subsequent heterogeneity analysis was conducted, differentiating between state-owned controlling enterprises and non-state-owned controlling enterprises based on the proportion of state capital, compared to state-owned controlling enterprises, the impact of the policy is more significant on non-state-owned controlling enterprises; Additionally, the policy effects across different economic regions of China were analyzed, revealing that the policy's effect is most significant in the eastern region, significant in the western region, but not significant in the central region. The conclusions of this study further enrich the empirical evidence of the micro-effects of environmental regulation, extending the research on the effects of the environmental fee-to-tax policy, and also provide suggestions for policymakers to formulate effective market-incentive-based environmental regulatory policies.

Authors: Liang Weimin , Cheng Lei
Published: February 2024

With the continuous increase in urbanization, the annual output of construction waste has consistently grown at a high speed. Based on extensive research and comparative analysis of relevant literature, this paper summarizes recent reinforcement methods for recycled concrete aggregate. The primary obstacle to utilizing construction waste resources is the significant amount of old cement mortar attached to the surface of recycled aggregate. This not only increases water absorption rate but also creates numerous weak interface transition zones in recycled concrete, greatly impacting its performance. By comparing and analyzing a large number of relevant literature on removing old cement mortar and enhancing the strength of recycled concrete interfaces, this paper examines their advantages, disadvantages, applicability, environmental benefits, etc., and proposes corresponding suggestions for developing recycled concrete aggregate technology. These findings aim to provide new insights into future research directions for reinforcing recycled concrete aggregates.

"Three Zones" Division of Spontaneous Combustion in Goaf of Y-type Ventilation Fully Mechanized Mining Face
Authors: Chen Yutao
Published: February 2024

The goaf of coal mine is accompanied by residual coal, and the possibility of spontaneous combustion determines whether the mine can work safely. Therefore, the division of "three zones" of spontaneous combustion in goaf under different working conditions is of great significance. This paper takes the 3154 fully mechanized coal face of Longmen Xianan Coal Mine as the research background to explore the "three belts" distribution under the Y-type ventilation mode. Based on the laboratory measured coal related spontaneous combustion characteristic parameters, the division standard of "three zones" is determined. Combined with the daily monitoring of the temperature and gas collection devices deployed on the site and the numerical simulation of the wind speed in the goaf, the comprehensive division of "three zones" in the goaf is realized. The results show that the range of "three zones" divided by temperature is similar to the range of oxygen concentration. The average width of heat dissipation zone and oxidation zone in the transport lane is 34.7m and 48.8m respectively. The asphyxiation zone is located at an average distance of more than 83.4m from the working face; The average width of the heat dissipation zone of the return air lane is 30.6m, the average width of the oxidation zone is 42.7m, and the average distance from the working face is more than 73.3m. In the numerical simulation, the width of the heat dissipation zone of the transport roadway is 35.0m, the width of the oxidation zone is 50m, and the asphyxiation zone is more than 85m from the working face. The width of the heat dissipation zone of the return air lane is 30m, the width of the oxidation zone is 40m, and the asphyxiation zone is more than 75m from the working face. The simulation results are close to the measured range of "three zones" of spontaneous combustion, and the width of "three zones" of return air roadway with Y-type ventilation is obviously different from that of transport roadway.
The Impact of Economic Policy Uncertainty on the RMB Exchange Rate
Authors: Xia Huatian
Published: February 2024

Based on the monthly data from July 2005 to August 2021, this paper analyzes the impact of economic policy uncertainty (EPU) on the RMB exchange rate by using VAR model and VECM model in stata16. The results show that there is a two-way interactive causal relationship between the economic policy uncertainty and the fluctuation of the RMB exchange rate between China and the United States. The increased uncertainty of China's economic policy will have a depreciating impact on the RMB exchange rate, and the increased uncertainty of the US economic policy will have an impact on the appreciation of the RMB exchange rate. Through the comparison of the impulse response diagram of the RMB exchange rate from the uncertainty of the economic policy of China and the United States, the impact of China's economic policy uncertainty on the change of the RMB exchange rate is greater than that caused by the uncertainty of the US economic policy, and these conclusions are consistent with the theoretical analysis. The policy implication of this paper is that government departments should strengthen the measurement and monitoring of global EPU, maintain the stability of their own macroeconomy, enhance the transparency and continuity of their own policies, and avoid the adverse impact of large changes in exchange rates on economic development.
Impact of Consumer Data Value on Pricing of Platform Enterprise
Authors: Teng Haiyun
Published: February 2024

Based on the background of digital economy, this paper mainly discusses the value of consumer data and the promotion effect of digital finance on enterprise entre-preneurship, and analyzes the differentiated choice of pricing strategy for platform enterprises under the situation that consumer data is known and unknown. Based on the linear city model, circular city model and vertical differentiation model, this paper constructs the competition system of platform enterprises in two situations: consumer data is known and consumer data is unknown, and reveals the influence of consumer data on the pricing strategy of platform enterprises. The research shows that consumer data can influence the pricing strategy of platform enterpris-es, and when consumer data is unknown to platform enterprises, they tend to choose unified pricing. At this time, consumers choose service types based on their preferences. If consumer data is known to platform enterprises, platform enter-prises will choose personalized pricing in order to compete with consumers in the market, but the price will be low, which will increase consumer welfare at the mi-cro level. Moreover, the development of digital finance based on the background of digital economy has a positive role in promoting new enterprises and affecting consumer welfare at the macro level, it has practical significance and profound re-search significance for the study of social welfare changes.

Purpose: To explore the relationship between job burnout in seafarers and subjective well-being and general self-efficacy, a structural equation model is constructed. Methods: This study conducted a questionnaire survey with seafarers as the research subjects, distributing a total of 451 questionnaires. Statistical analysis of the questionnaire data is performed using SPSS 26.0, and structural equation modeling is conducted using AMOS 24.0. Results: The constructed structural equation model demonstrated a good overall fit. Both subjective well-being and general self-efficacy are significantly negatively correlated with job burnout. Psychological resilience played a partially mediating role between subjective well-being and job burnout. Conclusion: Subjective well-being and general self-efficacy are two crucial influencing factors leading to job burnout in seafarers. Psychological resilience can mitigate job burnout levels by increasing subjective well-being, and it acts as a partial mediator between subjective well-being and job burnout.
The Role of Industrial Structure in the Impact of Environmental Regulation on Carbon Productivity
Authors: Liu Chenyang
Published: February 2024

In the context of global climate change, China has proposed the "Carbon peaking and Carbon neutrality goals" goal of carbon emissions will reach carbon peak by 2030 and carbon neutral by 2060. As a market-based environmental regulation policy to promote greenhouse gas emission reduction, carbon emission trading policy is expected to reduce carbon emissions and improve carbon productivity, among which industrial structure plays a regulatory role in the impact of carbon emission trading policy on carbon productivity. Using the provincial data of China from 2006 to 2019, this paper evaluated the influence of carbon emission trading policy on carbon emission, taking the industrial structure as the regulating variable, studied the industrial structure in the influence of environmental regulation on carbon emission, and tested the regression results of DID model through parallel trend test, placebo test and PSM-DID model regression. After the above research process, the following conclusions are drawn: the carbon emission trading policy has a significant positive promotion effect on carbon emission reduction, and it is further concluded that the industrial structure has a significant negative regulatory effect on carbon productivity under the carbon emission trading policy.

O presente estudo tem como principal objetivo investigar uso de tecnologias digitais na modernização e agilização dos processos de licitação pública presentes na literatura brasileira. A pesquisa baseia-se em uma revisão sistemática de fontes acadêmicas e literatura disponível para compreender o impacto da modernização, especialmente na eletronização dos procedimentos administrativos. Aborda a viabilização de serviços públicos digitais e a simplificação da divulgação de informações públicas. A modernização dos processos de licitação, apesar dos benefícios, enfrenta desafios, como infraestrutura sólida, capacitação e segurança digital. A inclusão digital é crucial para garantir equidade. Resulta em aprimoramento da transparência, ampliação da concorrência e redução de custos. A modernização é uma jornada contínua que traz benefícios substanciais, mas exige compromisso constante e baseado em dados. É importante garantir supervisão rigorosa e métricas de desempenho para o sucesso contínuo desse processo. Deste modo, conclui-se que a modernização dos processos de licitação pública por meio da inovação tecnológica é uma jornada contínua que traz benefícios substanciais para a administração pública e a sociedade como um todo.
Confianza social, confianza política y satisfacción con la democracia
Authors: Montero Gibert José Ramón , Zmerli Sonja , Newton Ken
Published: February 2024

Este artículo analiza las relaciones entre tres variables fundamentales dentro de la literatura sobre capital social. En él se discuten la conceptualización y operacionalización empírica de cada una de ellas y se examinan sus relaciones mutuas y el papel de algunas variables básicas, como el asociacionismo, en sus orígenes. Los datos utilizados proceden de las encuestas del proyecto Citizenship, Involvement, and Democracy (CID), realizadas en 12 países europeos entre 1999 y 2002. Los hallazgos empíricos caminan en dirección contraria a los de buena parte de la literatura en lo que hace a las relaciones entre confianza social y confianza política, entre confianza social y satisfacción con la democracia y sobre el papel de las asociaciones voluntarias para la creación de confianza social y política. Las implicaciones de estos hallazgos son metodológicas y sustantivas.
Las desigualdades de género en las ONG de desarrollo discursos, prácticas y procesos de cambio
Authors: Dema Moreno Sandra
Published: February 2024

Las ONG, como cualquier otro tipo de organizaciones sociales, reflejan las desigualdades de género en su estructura y funcionamiento interno. Este artículo va dirigido a analizar dichas desigualdades en las ONG de desarrollo, a través del estudio de las prácticas, dinámicas y discursos que se producen en el interior de las mismas. En este artículo se va a hacer especial hincapié en uno de los efectos de la desigualdad, la (in)visibilidad de las mujeres en este tipo de entidades, considerando las dos dimensiones de este fenómeno. Por un lado, se profundizará en la invisibilidad de las cuestiones de género, derivada de la desigualdad existente dentro de este tipo de organizaciones.Y, por otro, se estudiará la excesiva visibilidad de aquello que se sale de la norma, a partir de los procesos de cambio en los roles de género que se están produciendo en algunas ONGD.
