Authors: Soares Rosa L S , Saad Maria Auxiliadora N , Dos Santos Marcia S , Dos Santos Ana Maria R , Lima Giovanna Aparecida Balarini , Menezes Glauber Marcius
Published: July 2024

Background – A significant number of irritable bowel syndrome (IBS) patients report onset of symptoms after ingestion of a specific food, including those containing gluten. NCGS includes both intestinal and extra-intestinal symptoms which are related to the ingestion of gluten containing food-after exclusion of celiac disease (CD) and wheat allergy. The overlap between irritable bowel syndrome (IBS) and NCGS has been described but the knowledge of the etiopathogenesis of this clinical entity is incomplete. In Brazil, data on the prevalence of IBS and its association with food intolerance are scarce. Objective – To study the prevalence of SRGS in a group of volunteers diagnosed with IBS in a Brazilian community. Methods – A total of 400 volunteers over 18 years old were selected from students and staff of the Medical School of the Fluminense Federal University, Brazil. Participants completed a questionnaire divided in basic demographic information (age, sex), evaluation of IBS diagnosis in accordance with the Rome III criteria and self-reported food intolerance, including gluten. Results – Eighty-seven (21.7%) (Group I) [mean age 30.4±12.65 (77.4%) females] fulfilling the Rome III criteria for IBS. Twenty-six (32%) reported gastrointestinal symptoms after ingestion of food in general and 28 (32.1%) after gluten ingestion. Within the 313 volunteers non-IBS (78.2%) (Group II) [mean age 30.6±21.77, 215 (68.2%) females] 66 (21%) and 50 (15.9%) reported gastrointestinal symptoms after ingestion of food in general and gluten respectively. Demographic data (mean age and sex) were not statistically different when we compared the two groups of volunteers (p>0.05). Conclusion – The report of gastrointestinal symptoms after ingestion of food in general and gluten-containing foods were statistically different in the two groups (p<0.05). The interaction between IBS, food intolerance and NCGS needs to be better defined, since the role of diet in IBS and its feeding management is an essential condition for the treatment of most of those patients
Feline watching tourism in South America: Conservation, sustainability and impacts in the Pantanal and Patagonia
Authors: Dias Reinaldo
Published: July 2024

Tourism for the observation of large cats, such as the jaguar in the Brazilian Pantanal and the puma in Chilean Patagonia, has emerged as a powerful tool to promote biodiversity conservation and sustainable economic development. This article explores the opportunities and challenges associated with this form of tourism, highlighting best practices and strategies for maximizing benefits and mitigating negative impacts. The analysis reveals that big cat tourism can provide significant economic benefits to local communities, creating livelihoods and raising living standards. However, it is crucial to maintain a balance between economic benefits and ecological sustainability. Implementing capacity limits, strict regulations, and sustainable tourism practices are essential to prevent the degradation of natural habitats and animal stress. Tourism education plays a vital role in promoting responsible behaviors among visitors. Orientation programs and the presence of experienced guides help ensure that wildlife interactions are safe and informative. Additionally, collaborating with academic institutions to monitor and research the impact of tourism on feline populations and their habitats is critical for making informed decisions. The involvement of local communities is another critical aspect. Initiatives that ensure communities directly benefit from tourism strengthen local support for conservation efforts and create sustainable income streams. Habitat restoration projects and anti-poaching units, funded by tourism revenue, can promote ecological recovery and reduce threats to wildlife. Diversification of tourism activities is also recommended to distribute pressure on wildlife habitats and extend the stay of tourists. In addition to feline watching, cultural visits, ecological trails and other activities can promote conservation and environmental education. Jaguar and cougar sighting tourism presents a valuable opportunity to promote conservation and economic development. Adopting sustainable tourism practices, education, and community engagement are essential to ensure that this form of tourism continues to thrive, benefiting both wildlife and local communities.

Published: July 2024

In the talent cultivation system of higher education in China, the group of graduate students is at the highest level. The effectiveness of graduate ideological and political education not only affects the quality of graduate education in universities, but also relates to the rise and fall of the future socialist cause. In recent years, the annual expansion of graduate enrollment has brought enormous opportunities and severe challenges to the ideological and political education work in universities. Against the backdrop of the strong advocacy of the Party and the state for cultivating moral character, the fundamental task of cultivating moral character should be integrated into the work system of graduate ideological and political education. Cultivating moral character is the historical mission of graduate ideological and political education, and building a collaborative education system for graduate ideological and political education is also an inherent requirement for the success of graduate students.
Evaluation of Importance of Birds from Non-Tidal Wetlands: A Review
Authors: Lubal Maruti J.
Published: July 2024

Wetlands are the lands transitional between terrestrial and aquatic eco-systems where the water is usually at or near the surface or the land is covered by shallow water. They are most productive, valuable, and provide a wide range of goods and services. Wetland birds rely on waterways for survival and each bird species has its own requirements for food, shelter and breeding sites. Monitoring of wetland birds is an engaging activity that provides researchers with an insight into the functioning and health of wetlands. Despite the high value of services derived from wetlands, they have been systematically drained and filled to support agriculture, urban expansion, and other developments. Agriculture, climate change, draining, dredging, introduced species, pollution, salinization, and urbanization are the major threats to wetlands. In light of these observations, the aim of this review is to update recent information from the available literature relating with the ecosystem services provided by birds from non-tidal wetlands.

Technology as A Determinant of Mother's Knowledge About Stunting In Toddlers Aged 1-5 Years Old Tanjung Sari Natar Village Selatan
Authors: Syahroni Arfan , Nugroho Tri Adi
Published: July 2024

Stunting refers to a condition when a child experiences impaired growth and development for his age due to malnutrition. Factors that cause stunting can be found during pregnancy or the early stages of child growth. In this study, researchers wanted to find out about the use of technology as a determinant of mothers' knowledge about stunting in toddlers aged 1-5 years. This type of research is quantitative using a cross-sectional study design. The design of this study was chosen to identify the influence of variables on Android mobile phones and growth and development applications on maternal knowledge about stunting aged 1-5 years. The research population was all mothers who had toddlers aged 1-5 years in Tanjung Sari Natar Village, South Lampung. The sample size using the non-probability sampling quota sampling technique is 50 respondents. The test was carried out using the Pearson correlation test, whether ownership of an Android mobile phone and growth and development applications is related to a mother's knowledge about stunting. The results of a significance value > 0.05 (cellphone 0.195, growth and development applications 0.113) mean that there is no significant correlation between owned mobile phones and growth and development applications, with knowledge of stunting.

Objective: Biotechnological xylitol production from secondary agricultural residues is a promising approach for a sustainable and environmental purpose. Lignocellulosic biomass is a significant feedstock for biofuel and biochemical production. Its accessibility, cost-effectiveness, renewability, and environmental friendliness make it an attractive alternative to fossil fuels and other conventional sources of energy and chemicals.
Materials and methods: In this study, the conversion of xylan to xylose in a pistachio shell was provided with a novel technology of a microwave-assisted high-pressure CO2/H2O system. Xylose rich pistachio shell hydrolysate was utilized by Candida tropicalis ATCC 13803 for xylitol production. Different concentrations of xylose (50, 100, and 150 g/L) were employed for xylitol production in shake-flask.
Results and conclusion: HMF and furfural were completely removed from xylose-rich hydrolysate by activated charcoal. The improvement in yeast performance was limited with increasing xylose concentration. The highest xylitol produced by C. tropicalis from pistachio shell hydrolysate (65.15 g/L) and the maximum yield of xylitol 0.66 g/g with 100 g/L xylose were obtained in shake-flask whereas xylitol produced at 50 g/L and 150 g/L xylose were 0.65 and 0.37 g/g, respectively. Volumetric productivity at 100 g/L of xylose was 1.28 times and 1.84 times higher compared to xylose concentrations of 50 g/L and 150 g/L, respectively. Xylitol production performance (71.73 g/L) of detoxified pistachio shell hydrolysate at 100 g/L of xylose was almost identical to pure xylose. However, the yeast was not able to consume xylose at 150 g/L resulting in no xylitol production.

An Exploration of the Cinematic Adaptation of Manto’s Short Stories in the Light of Foucault’s Discourse Theory
Authors: Pratima Purwar and Prof. Alka Rani Purwar
Published: July 2024

This paper explores the cinematic adaptation ‘Mantostaan’, which is a compilation of the four short stories by Saadat Hasan Manto: ‘The Last Salute’, ‘Open It’, ‘The Assignment’, and ‘Colder than Ice’ in the light of Foucault’s Discourse theory. These works are the English translations of Manto’s Urdu works and are taken resort to for deeply observing the visual content of the film adaptation. For Foucault (1977), it is through discourse (through knowledge) that we are created; and that discourse joins power and knowledge, and its power follows from our casual acceptance of the “reality with which we are presented”. The discourse theory is applied on the dialogues exchanged by the characters of the film in the background of the horror during the partition of India occurred in 1947. It also discovers how various kinds of situations, in the turmoil of communal riots, led the characters holding the power position and thus dominating the discourse. The characters of the film thus, driven by their knowledge, create or participate in the discourse. These discourses shape out the situations, consequences of which are faced by the people. Thus, the paper taking into account the partition fracas, focuses upon the situations created by the discourse throughout the time of communal animosity and upon its bewildering aftermaths affecting people’s lives.

Published: July 2024

Actualmente en la mayoría de instituciones, incluyendo la red de salud Abancay, se utiliza estadística tradicional con el fin de determinar tendencias sobre un conjunto de datos que se centra en una sola variable, es complicado aplicar este tipo de análisis a conjunto de datos multivariados, que son los que usualmente se obtienen en los programas de control de calidad de agua y, que excluye diferencias entre las variables analizadas y sus relaciones. El objetivo del estudio es realizar una comparación entre las diferentes técnicas estadísticas multivariables y redes neuronales artificiales, con la finalidad de relacionar y clasificar las variables. Para realizar esto se eligió dos técnicas de estadística multivariada, análisis de componentes principales (ACP) y análisis discriminante (AD) y dos tipos de redes Neuronales artificiales, de aprendizaje no supervisado, hebbiano (RNAH), y de aprendizaje supervisado, perceptrón multicapa (RNAPM), el tipo de investigación que se usará en el estudio será investigación aplicada de enfoque cuantitativo, con un nivel de investigación explicativo y con un diseño transversal. Dada la comparación entre el análisis de componentes principales y la red neuronal artificial de tipo Hebbiano, se obtuvo que las redes neuronales pudieron asociar mejor las variables que el análisis de componentes principales. En la segunda comparación entre el análisis discriminante y la red neuronal artificial perceptrón multicapa los resultados fueron buenos para el análisis discriminante debido a que obtuvo un 95% de clasificación correcta, mientras que la red neuronal artificial obtuvo un 74.6%, sin embargo, debido a las limitaciones del análisis discriminante, se infiere que la red neuronal artificial perceptrón multicapa es un mejor modelo a escoger.

Fine Tuning of the BitCover Algorithm for Interactive VoD Streaming over 5G Cellular Networks
Authors: Rodrigues Carlo Kleber da S. , Rocha Vladimir
Published: July 2024

The BitCover algorithm is an adaptation of the popular BitTorrent algorithm for interactive Video-on-Demand (VoD) streaming over 5G cellular networks. This algorithm has already proven to be an effective solution for granting adequate bandwidth utilization within each cell site, which turns out to be essential for unlocking the whole potential of the 5G technology. Despite its attractive performance, we though wonder if there is still space for optimization since four of its configuration parameters are identical to those of the original BitTorrent, being set with the same numerical values. These parameters are δt (unchoking time), Np (number of neighbors a peer has), y (number of data slots a peer’s upload capacity is divided into), and z (number of peers randomly selected in optimistic unchoking). To tackle this issue, we therefore carry out simulation experiments to hopefully determine a more adequate configuration setup for the three first parameters just mentioned, leaving the specific analysis of the last parameter (i.e., z) implicit since it is directly related to the third parameter (i.e., y). Among the major findings, we highlight that BitCover’s original performance is enhanced at about 16.7% in terms of download rate, and at 50.1% in terms of discontinuity time. To complement this study, we also present a detailed competitive analysis against two other recent literature proposals, mainly to show the overall effectiveness of the optimized version of the BitCover algorithm. Within this context, our pivotal contribution is to offer helpful insights for designing protocols aimed at 5G cellular networks. Finally, this paper ends with general conclusions and outlines future directions.
A Study on Heavy Metal Contamination of Yard Soils and its Remediation Potential by Weedy Species
Authors: Garuda Ramoji , Daka Gopamma , Kolli Suresh Kumar , Namuduri Srinivas
Published: July 2024

The present study was undertaken to analyse the phytoremediation potential of weedy plants growing at dump yards. Two dump yard sites were chosen. Based on the distribution and abundance, 11 weedy species were collected bi-annually using the plot method along with soil samples. Both plants and soils were analysed for heavy metals, and the bioconcentration factor (BCF) was calculated to assess the extent of soil contamination and the remediation potential of weedy plants.
The weed plants collected from two yard sites showed an accumulation of metals, and the rate of accumulation varied among plant species. In the species at the dumping yard site, a higher accumulation of metals was observed for Panicum ciliare (As and Zn), Indigofera hirsuta (Cd and Ni), Chloris barbata (Cr), and Indigofera aspalathoides (Pb). Goiania macrocarpa has accumulated more As, Cu, Ni, and Zn metals in the industrial yard. The accumulation levels in plant tissues were assessed through BCF in the whole plant. The study results confirm that Panicum cillarae, Indigofera hirsuta, and Sida acuta at dump yard soils and Indigofera aspalathoides at industrial yard soil reported BCF values of more than one, indicating the potential of these plants for phytoremediation for selected metals.
Six of the 11 weedy species were specific to accumulating metals from yard soils. They are Indigofera aspalathodies for Cd; Sida acuta, Panicum ciliare, and Indigofera hirsuta for As; Oldenlandia corymbose for Zn and As; and Gouinia macrocarpa for Zn. The findings suggest that weedy species growing naturally in the two yards sites adopted higher concentrations of the metals and can accumulate them to a higher degree in their body parts.

Authors: Nguyen Thao P. , Hoang Ha N. , Dang Huyen T. T.
Published: July 2024

While great attention has been focused on urban waste management, waste management in rural areas is still much less concerned both at investigation and investment levels. This study aims to survey household waste generation, treatment methods, and willingness-to-pay in a low-income province in the northern part of Vietnam. The results showed that the solid waste generation rate varied depending on household size and economic conditions. Specifically, they were 0.62 kg/person/day, 0.49 kg/person/day, and about 0.25 kg/person/day, respectively, for people living in the provincial city, town, and communes. On average, the waste generation was about 0.33 kg/ person/day, which was much lower than in other provinces of Vietnam; however, this rate was at the same level as other low-income provinces internationally. The surveyees were willing to pay only about US$ 0.25/HH/month (accounting for 0.25% of HH monthly expenses). This payment rate was low, leading to many challenges in proper waste management in rural areas.
Political Budget Cycles and Mayoral Influence in Latvian Municipalities: An Examination of Revenue, Expenditure, and Electoral Dynamics
Authors: Stučka Malvine
Published: July 2024

Budget allocation and budget planning can be used in different ways. In addition, it can be part of a political budget cycle. Previous research has highlighted the political budget cycle's existence in European countries, demonstrating its impact on public revenue and expenditure near elections. However, citizens often lack awareness of this phenomenon, underscoring the need for vigilant scrutiny. In addition, elected politicians increasingly rely on voters for support, targeting them during budget allocation and election campaigns. In Latvia, the mayors have a role in budget planning because they work full-time and are the head of the financial commission. In Latvia, despite a lack of trust in local politicians, there is a tendency for most of the mayors to be re-elected. The article aims to examine what kind of role the council’s chairperson has in the local government's budget allocation process and what factors affect the budget allocation process in Latvia. The article’s scope encompasses the years 2009 to 2017, spanning two election terms (2009-2013; 2013-2017), and focuses on eight state cities in Latvia, excluding the capital city, Riga. Notably, local governments with a higher percentage of council members from the mayor's party tend to exhibit higher expenditure levels. The findings of this study suggest that various socio-economic and political factors impact the financial performance of local governments in Latvia. These results underscore the significance of population and unemployment in shaping local government expenditures. Simultaneously, this research has highlighted the importance of political factors such as the majority in the local government and time spent in the mayor’s position. Moreover, it reveals that long-serving mayors and a majority in the council also influence budget allocation decisions. This article's implications can guide policymakers in making informed decisions regarding municipal budget expenditures and revenues.
The Prerequisites for Successful Worker Takeovers and Their Implications for Organised Labour
Authors: O'Connell David
Published: July 2024

This book evaluates the effects of trade worker takeovers (WTOs)—the recuperation of workplaces by workers—on trade union power resources. Deploying a mixed methodological framework to identify the prerequisites for successful labour-strengthening WTOs and using an adaptation of the power resources approach as a theoretical framework, it critically evaluates the experiences of the National Union of Mineworkers (NUM) in the United Kingdom, the United Food and Commercial Workers Unions (UFCW) in the United States and the Sindicato dos Metalúrgicos do ABC (SMABC) in Brazil. It finds that, under certain circumstances, WTOs can strengthen the overall power resources of trade unions and identifies the prerequisites for success in that respect.

Published: July 2024

With the ongoing amendment of the European Union legislation on the treatment of municipal wastewater, stricter requirements for the removal of pollutants are expected, which calls for the need for innovative wastewater treatment technologies. Our research was focused on the removal of ammonium nitrogen from municipal wastewater by nontraditional processes based on the use of adsorption processes on zeolite (ZEO) and ozone. Adsorption, adsorption-regeneration, and adsorptive ozonation processes were applied. All processes were carried out in a completely stirred reactor (CSR) and a jet-loop reactor (JLR) with external recirculation of the reaction mixture. Experimental measurements were carried out with real municipal wastewater after mechanical treatment. The best results were achieved in the adsorption-regeneration process, which was implemented in a current loop reactor. An average ammonium nitrogen removal efficiency of 53.1% was obtained by adjusting the pH value to 10.0. Average values of 46.2% and 49.2% for chemical oxygen demand (COD) and total organic carbon (TOC) removal efficiencies are an added value of the process. The values of ammonium nitrogen, COD, and TOC removal efficiencies in individual cycles confirm the high stability of the process.
Great Expectations: Change and Continuity in Academic Roles and Tasks
Authors: Avramovic Aleksandar
Published: July 2024

This study explores the changing expectations towards the work of senior academics in Norway. By utilizing role theory concepts, as well as literature on university branding and academic recruitment, it examines how academic roles and tasks have changed, as well as the “ideal academic” depicted by universities themselves at the hiring stage. Data for this paper was collected from ten public universities in Norway over a period of 20 years and includes job advertisements (N = 1,744) for professor and associate professor positions. The study found that higher education institutions (HEIs) have become more specific when describing their expectations of academics, increasingly using job advertisements as marketing and branding artifacts. The analysis also demonstrated that universities in Norway behave strategically and have organizational goals in mind during the hiring process of new academics. The results related to role change are less conclusive but indicate that there is a general trend towards focusing on research quality and metrics, as well as acquiring research funding from external sources as part of a researcher role. Teaching expectations also increased, but more in the light of meeting organizational teaching needs, than being an integral part of academic life. Finally, there are increasing expectations towards third mission activities, while the administrative role is strategically unadvertised, as it is a less attractive part of academic job.

Published: July 2024

Teknolojinin gelişmesiyle beraber insanların dünyayı anlama, etkileme ve değiştirme biçimleri büyük oranda farklılaşmıştır. Bu farklılığın boyutunu anlamaya çalışan felsefe, teknolojinin insan yaşamını ne düzeyde etkilediğini inceler. Bu etkinin insani özgürlüğü, ulusal kimlikleri ve ahlaki değerleri hangi zemine taşıdığını ortaya koymaya çabalar. Bu değişimin gerçekleştiği bir alan da şüphesiz bireysel mahremiyet alanıdır. Teknolojinin gelişmesi kişisel verilerin toplanması, depolanması, işlenmesi ve paylaşılması gibi mahremiyet ile doğrudan ilişkili pek çok sorunu ortaya çıkarır. İnsanların dijital platformlarda yaptığı etkileşimler, izledikleri videolar, oluşturdukları profiller mahremiyet endişelerini artırmaktadır. Bu çalışmada veri madenciliği ve hesaplamalı dönüşüm çağında mahremiyetin ne durumda olduğu ve nasıl önlem alınabileceği üzerinde durulacaktır. Ayrıca devletin bireysel mahremiyeti korumak için ne tür önlemler alması gerektiği vurgulanacaktır. Son olarak mahremiyet anlayışımızın değişimi ve mevcut durumun anlaşılmasına dair bazı örnekler verilecektir.

Background: Peroxisome proliferator activated receptor gamma (PPAR-γ) agonists are beneﬁcial in the treatment of diabetes by stimulating insulin sensitivity and antagonizing hepatic gluconeogenesis. Objective: The aim of this study was to investigate the antidiabetic eﬀect of phytocompounds synthesized from crude extract and fraction of Napoleonae imperialis, using GC-MS analysis and molecular docking studies. Methods: Crude extract and fraction from N. imperialis were subjected to gas chromatography mass spectrometry (GC-MS) for identification of bioactive compounds in the plant and molecular docking of Napoleonae imperialis on human PPAR-γ protein was determined by Auto/Vina in Pymol 4.2 and compared with Glibenclamide, a known agonist of PPAR-γ. Results: Our present study reports the phytochemical analysis of the crude extract and fraction from the leaves of Napoleonae imperialis. Sixty one (61) and eighty four (84) compounds were revealed through GC-MS analysis of the crude extract and fraction of N. imperialis. Molecular docking revealed that Dibutyl phthalate, 7,9-ditert-butyl-1-oxaspiro (4,5) deca,6,9-diene,2,8-dione and Guaiol bound favourably to the target receptor involved in glucose metabolism with a binding score of -7.3 kcal/mol and -7.5 kcal/mol against PPAR-γ. Conclusions: N. imperialis methanol leaf extract and its bioactive compounds Dibutyl phthalate, 7,9-ditert-butyl-1-oxaspiro (4,5) deca,6,9-diene,2,8-dione and Guaiol had a signiﬁcant antidiabetic activity against PPAR-γ. The molecular binding interaction of an in-silico data demonstrated that Guaiol has more speciﬁcity towards the PPAR-γ binding site and could be a potent antidiabetic compound.

Published: July 2024

This paper explores benchmark tracking behavior of Country ETFs during the US market crash in March 2020, following the Covid–19 pandemic announcement by the World Health Organization (WHO). Using daily data spanning January 22, 2020, through April 17, 2020, we examine the tracking errors of 37 iShare country ETFs, 19 of which track developed markets while the remaining 18 track emerging markets.  We run one and two–factor pricing regressions for the country ETFs and measure the tracking errors from the regression residuals. We find that 17 out of 19 developed market ETFs tracked their underlying benchmarks closely during the pandemic, while only 1o out of 18 emerging market ETFs tracked their benchmarks closely during that turbulent market period. The findings indicate that the developed markets country ETFs remained more useful investment vehicles for international diversification during the Covid–19 pandemic than their emerging market counterparts.
