The present study aimed to evaluate the effects of endogenous compared to commercial probiotics on the growth, digestive enzyme activity, and non-specific immunity of sandfish juveniles. Treatments were: A. diet without probiotic; B. diet supplemented with endogenous probiotics Gamma proteobacterium strain M-4, Bacillus subtilis strain Q-1, Bacillus sp. strain E-2; C. diet supplemented with a commercial probiotic containing B. subtilis, B. licheniformis, and B. pumilus. The research was conducted for 4 months using 12 plastic containers, 30 juveniles each (initial weight of 2.72±0.37 g, mean ± standard deviation). From each container, ten samples were taken randomly every 14 days and weighed and three intestine samples at initial and every following month to analysis enzyme activities. At the end the study, all juveniles were counted and weighed individually, and performed a challenge test by injected a 106 CFU ml-1 Vibrio azureus strain 4C-1 at 0.1 ml/ind. Immune response observed were: total coelomate and gene expression (SOD, CAT, LZM) by Quantitative real-time PCR. The specific growth rate of juveniles fed by diet B was significantly different from treatment A (P<0.05), its final weight was higher compared to diets A and C (P<0.05). Protease, lipase, and amylase activity in treatment B was higher compared to C and A (P<0.05). The survival rate, total coelomocyte count, gene expression after being challenged were higher in treatment B compared to C and A (P<0.05). The present study showed endogenous probiotics promote growth, improve digestion enzyme activity, and stimulate non-specific immune responses.

Published: July 2023

Cyclocheilichthys apogon (Beardless Barb fish) and Cyclocheilichthys armatus (Hihgfin Barb fish) in West Sumatra is known by the local name Turiak and Catua fish, respectively, are economically important species. Reducing populations and limited biological information about these fishes make their genetic diversity and phylogenetic relationships crucial. The genetic variation was investigated by analyzing the sequencing of a part of mitochondrial DNA Cytochrome b (Cyt b) and Cytochrome oxidase-I (COI) genes of 23 individuals collected from West Sumatra populations. Phylogenetic analysis revealed the monophyletic lineage of the Cyclocheilichthys group and supported Anematichthys as the synonym of Cyclocheilichthys. C. armatus was closely related to C. janthochir and separated from C. apogon with sequences divergence were 12.7-14.0% (Cyt b) and 9.4%-10.0% (COI). C. apogon and C. armatus have low haplotype diversity and genetic diversity, respectively. Genetic diversity within and among populations with sequences divergence was 0.0-0.8% (Cyt b) and 0.0%-0.7% (COI), respectively. The low-level diversity may signify a possibility of gene flow within and among populations. The current data suggests all populations as a single stock unit. Present genetic information is important to establishing effective population management, conservation, and breeding strategies for Turiak and Catua fish.

Asiatic palm weevil Rhynchophorus vulneratus Panzer is one of the key pests of coconut in Indonesia. Information regarding the spatial distribution of R. vulneratus is needed to support Integrated Pest Management and can be analyzed using Geographic Information System (GIS). Initial studies on the interaction between R. vulneratus and Oryctes rhinoceros were also studied in this study. This research aimed to analyze the spatial distribution of R. vulneratus using GIS and its interaction with the Coconut beetle Oryctes rhinoceros. The research was conducted in Yogyakarta as a habitat model (0-1,000 masl). R. vulneratus and O. rhinoceros were catched by installing aggregation pheromone traps hanging to coconut plants at 1.7 m above ground. The research was conducted during the rainy and dry seasons. The spatial distribution of R. vulneratus was analyzed by IDW interpolation using QGIS 3.22, whereas its interaction with O. rhinoceros was analyzed by the Pearson correlation test using SPSS 22. The results showed low number of R. vulneratus captured in the Yogyakarta area during the rainy season at 0-1,000 masl. However, the number of R. vulneratus during the dry season has increased, and the distribution rate was dominated by medium to very high levels, especially at an altitude of 0-300 masl. The study also showed that the number of R. vulneratus was not influenced by the number of O. rhinoceros, which suggested that the abundance of O. rhinoceros cannot accurately predict the abundance of R. vulneratus.

Published: July 2023

The contribution of halophilic microorganisms to the quality of salts produced in solar salterns has recently been recognized but not clearly understood. Using metagenomic 16S rRNA gene sequencing approach, we showed the microbial composition difference between the Tuban crystallization pond (CP-Tuban) that produces low-quality salt and CP-Sampang as a representative solar saltern that yields high-quality salt. Dominant classes in both traditional salterns were represented by γ-proteobacteria and halobacteria that occurred at higher prevalence in CP-Sampang. Microbial taxa, including beneficial genera, in CP-Sampang were more diverse and abundant compared to CP-Tuban. Among 180 genus-level OTUs identified in CP-Sampang, 127 of them were considered unique due to their absence in CP-Tuban. Higher levels of dissolved oxygen (DO) and nutrient (phosphate, nitrate, and ammonia) in the seawater reservoir (SR) of Sampang may contribute to more diverse phytoplankton genera, which could support the growth of beneficial heterotrophic microbes that positively affect the salt quality of the CP-Sampang. Low number of Dunaleilla sp. in both CPs do not seem to influence the quality of salts produced. The outcome of these comparative studies provides new insights into the contribution of diverse microbial taxa in correlation with physico-chemical parameters and phytoplankton communities to the high quality of salts produced in traditional solar salterns. The presence of beneficial genera in the enriched microbial cultures could provide an important basis for further applications, such as improving the quality of salt produced and producing unique compounds and enzymes.

Purwoceng (Pimpinella pruatjan) is an Indonesian native plant but difficult to cultivate. Hydroponics can be used as a solution for purwoceng cultivation. Hydroponic types and nutrient concentrations can affect purwoceng’s productivity. This study aimed to determine total phenolic content (TPC) and total flavonoid content (TFC), changes in steroid, and antioxidant capacity due to two hydroponic types (nonrecirculating and recirculating drip) and three nutrient concentrations (1,000, 1,500, and 2,000 ppm). Purwoceng was determined for its moisture content, ash content, and dry weight, and extracted with ethyl acetate for gas chromatography-mass spectrometry analysis and with ethanol for TPC, TFC, and antioxidant capacity. The data were analyzed statistically and grouped using principal component analysis (PCA) and heat map analysis (HMA). Nonrecirculating drip with high nutrient concentration at the aerial part was the best treatment to produce high TPC, TFC, and antioxidant capacity. There were no significant changes in steroid content. PCA showed that purwoceng extracts could be grouped in to two groups, i.e. aerial and root groups. HMA showed that purwoceng extracts could be distinguished from the abundance of palmitic acid and stigmasterol. The antioxidant capacity of purwoceng was directly proportional to the TPC value and also related to the presence of phytol, stigmasterol, and palmitic acid.

The article is devoted to the analysis of administrative and other measures in Ukraine aimed at reducing the number of coronavirus disease. Considerable attention is paid to administrative proceedings in the context of the spread of coronavirus disease. The state of the legislation that exists today in Ukraine is analysed. It is noted that most of the regulations are quite positive and in compliance with their requirements, it was possible to stop the spread of coronavirus disease. However, despite the fact that the number of infected people has decreased significantly compared to previous years, the risk that the coronavirus will gain momentum remains high. The reasons for this phenomenon in most cases are, firstly, non-compliance with the requirements of quarantine, wearing masks and other measures, and secondly, the small number of people who are vaccinated and thus spread the coronavirus. This problem is global, it is probably necessary to develop appropriate regulations at the United Nations level and implement the requirements of such regulations in the legislation of all countries.
Relevant Market - Digital Challenges
Authors: Kalesná Katarína
Published: July 2023

Market definition is a specific and important tool used in European competition enforcement practice to identify boundaries of competition between undertakings; it is used both in antitrust and merger cases. The EU Market Definition Notice was adopted in 1997 in conditions of conventional markets with relatively stable market structures. With respect to recent development, especially digitalisation and globalisation of economy, the Commission launched the process of evaluation of the Notice in March 2020, and the revised notice has to be published in Q3 2023. Having in mind profound changes challenging various aspects of the original market definition, the article lists at first the most important features of digital economy, especially importance of innovation conditioning rapid changes of the market. Regarding the fact that the main principles of market definition were confirmed as sound until now, the short characteristics of the relevant market follow. The core part of the article aims to present and discuss different approaches to market definition, methods of market assessment included, taking into account the corresponding case law and legal writings reflecting digital circumstances making markets interconnected like never before. The article confronts also sometimes differing opinions of theory and practice in approach to market definition. Analysis is carried out with the ambition to find out whether it is possible – based on case specific approach of competition authorities – to draw general conclusions necessary for coherent conception of the revised market definition, or at least unifying recommendations for the legal practice for the sake of legal certainty. Outcomes of the analysis are summarised in the conclusion, in context with the draft market definition notice.

Published: July 2023

K3 surfaces have been studied from many points of view, but the positivity of the cotangent bundle is not well understood. In this paper we explore the surprisingly rich geometry of the projectivised cotangent bundle of a very general polarised K3 surface $S$ of degree two. In particular, we describe the geometry of a surface $D_S \subset \mathbb{P}(\Omega_S)$ that plays a similar role to the surface of bitangents for a quartic in $\mathbb{P}^3$.

The minimum covering energy is the summation of singular values of the minimum covering matrix. Upper and lower bounds for minimum covering energy are established and also derive some relationship between minimum covering energy and energy of semigraph G.
Staunen: Eine Poetik
Authors: Gess Nicola
Published: July 2023

Keine Kunst ohne Staunen? Zur Begründung von Ästhetik und Poetik in einer doppelbödigen Emotion. Dass das Staunen der Anfang der Philosophie sei, ist ein akademischer Gemeinplatz. Dass es aber auch grundlegend für die Begründung der modernen Ästhetik und Poetik ist, zeigt Nicola Gess in ihrem neuen Buch. Anhand von Beispielen aus Literatur und Philosophie vom 18. Jahrhundert bis zur Gegenwart (z.B. Breitinger, Burke, Kant, Tieck, Bloch, Brecht, Benjamin, Schrott, Hoppe) fragt sie: Staunen - was heißt das heute, was hieß das damals? Was wollten die Dichter und Denker damit befördern? Moralische Besserung, Hochachtung für den Künstler, Erkenntnissuche, Training der Nerven, Belebung der Phantasie, oder gar politischen Protest? Welche rhetorischen und literarischen Tricks setzten sie ein, um ihr Publikum zum Staunen zu bringen? Und was ist die Relevanz des Staunens für Kunst und Kunstreflexion heute? Auf Tuchfühlung mit einer Ästhetik der Affirmation ist das Staunen immer auch der anhaltenden Irritation, dem Zweifel und der Kritik verpflichtet.

The effect of aerodynamic factors on the rolling stock and railway infrastructure has been analysed. The formation of air mass structure in tunnel structures during the movement of high-speed rolling stock has been investigated. The processes of aeroelastic interaction of rolling stock with tunnel portal structures are analysed by means of numerical simulation. The description of mathematical models and the ways of their three-dimensional realization in the Solid Works Flow Simulation software complex are presented. Methods of finite elements and volumes for the solution of the set tasks are used. The results of the numerical research of velocity fields near the tunnel portal area obtained with the help of the developed mathematical models for the cases of entry and exit of the rolling-stock into the tunnel are given. The complex structure of air masses formation in the gap between the train body and tunnel lining which leads to increased resistance to the train movement in the tunnel is revealed. The patterns in the changes of pressure dynamics on the surface of the head fairing when the train enters the tunnel are found. The fact of negative effect of high and low pressure zones, as well as their abrupt difference, on the locomotive crew and passengers has been established.

Today, the technological, scientific and industrial use of micro- or nano-scale products has rapidly expanded. Nanoparticles are added to metal, ceramic and polymer materials to produce nanocomposite materials. Polymer matrix nanocomposites have advantages over other materials in terms of weight, performance and price. As known from the literature, imparting electrical conductivity to thermoplastic materials such as polylactic acid (PLA) is possible. The industrial use of thermoplastic matrix has been the focus of nanocomposites due to its low cost, ease of production and recycling. Research on the use of 3D printers in the production of nanoscale-doped thermoplastics has been less common. 3D printing is an additive manufacturing method compared to traditional processing methods. Additive manufacturing is based on adding layer by layer to reduce production costs and reduce the production cycle. This study prepared nanocomposite material by adding nano-sized graphene and Si3N4 to PLA material at 0.5, 1, 2 and 3 wt. %. The prepared polymer matrix nanocomposite groups were produced using a fused filament fabrication (FFF-3D) printer and their electrical conductivity was examined at the five different points by the four-point probe method. According to the test results, the electrical conductivities of 1 and 2 % doped PLA are very close. But the 1 % doped samples is the composite group with the best conductivity with a value of 153.44 S/m. A value of 151.25 S/m followed this for 2 % doped PLA and 138.57 S/m for 3 % doped PLA. Thus, it was concluded that the electrical conductivity was reduced with the increased dope rate. Also, all samples' hardness was measured by the Shore D test. Although the increase in the hardness value of the samples did not affect as much as the increase in the dope ratio, the hardness values increased with the increase in the nanoadditive ratio.

Authors: Anggarani Pribudi Anggarani Pribudi
Published: July 2023

The study aims to identify the implementation of Community-based Tourism to sustain Giriloyo Batik Tourism Village as a sustainable tourism destination. The identification analysis of the Community-based approach is based on thirteen fundamental factors of the ideal Community-based Tourism developed and adopted from related existing literature. This study is a qualitative study with an in-depth interview and a thematic analysis method.  The results of the study showed that tourism development began after Yogyakarta’s earthquake through supports from NGOs and the Government. Community-based Tourism is implemented which has the characteristics of the thirteen factors of the ideal model of Community-based Tourism I identified. However, there is a difference between the ideal and the fact. The most remarkable gap is in community participation, which in Giriloyo is limited and very active within the Batik Association led by the core members. Stakeholders’ roles are crucial in enabling tourism to flourish in Giriloyo Village. The primary stakeholders are Village Government, Local and Regional Tourism Offices Department, and NGOs. Community-based Tourism has positive impacts, mainly in terms of socio-cultural, economic, and environment. Despite the positive impacts, the community is still struggling with several issues, such as regeneration within the organization, domestic waste management, and product innovation. Concrete efforts are needed to ensure the sustainability of Giriloyo Batik Tourism Village in the long-term.

Published: July 2023

To discover the geopolitical orientation and opinions of the Armenia’s youth regarding Russia’s war in Ukraine in the context of regional security issues, a sociological study was conducted in Yerevan and Armenia’s provinces in 2022. It was carried out by specialists from the Faculty of Sociology of the Yerevan State University, in cooperation with the Konrad Adenauer Foundation office in Armenia, and Socies expert center. The study aimed to discover the youth’s perceptions of the reasons for Russia’s war in Ukraine, which started on February 24, 2022, including its possible impact on the region. The research was carried out from October 22, 2022 to November 22, 2022 with youth (18-35 age group) residing in Yerevan (the capital of Armenia) and all provinces of Armenia, using the focus group discussion method. In this paper, we discuss conclusions drawn from focus group discussions with Yerevan residents. The perceptions of the Russian-Ukrainian conflict by Armenia’s youth refers to its geopolitical nature, to the interests of Russia, NATO, EU, USA, Turkey in the post-Soviet space, as well as to personal qualities, approaches, and issues of the leaders of Russia and Ukraine. In general, according to Armenian young people, Armenia should remain as neutral as possible in its position on the war in Ukraine, taking no side in this conflict.

Published: July 2023

Introduction: This study determines the sensitivity and specificity of positron emission tomography/magnetic resonance imaging (PET/MRI) parameters in predicting treatment response in patients with localised rectal cancer who have undergone preoperative chemoradiotherapy (CRT).

Method: Patients with stage I–III adenocarcinoma of the rectum planned for preoperative CRT followed by surgery were recruited. Patients had PET/MRI scans at baseline and 6–8 weeks post-CRT. Functional MRI and PET parameters were assessed for their diagnostic accuracy for tumour regression grade (TRG). Nonparametric receiver operating characteristic analysis was employed to determine the area under the ROC curve (AUC), and the sensitivity and specificity of each quantile cut-off.

Results: A total of 31 patients were recruited, of whom 20 completed study protocol. All patients included had mid or lower rectal tumours. There were 16 patients (80%) with node-positive disease at presentation. The median time to surgery was 75.5 days (range 52–106 days). Histopathological assessment revealed 20% good responders (TRG 1/2), and the remaining 80% of patients had a poor response (TRG 3/4). When predicting good responders, the AUC values for percent maximum thickness reduction and percent apparent diffusion coefficient (ADC) change were 0.82 and 0.73, respectively. A maximum thickness reduction cut-off of >47% and a percent ADC change of >20% yielded a sensitivity and specificity of 75%/95% and 75%/73%, respectively.

Conclusion: Parameters such as percent maximum thickness reduction and percent ADC change may be useful for predicting good responders in patients undergoing preoperative CRT for rectal cancer. Larger studies are warranted to establish the utility of PET/MRI in rectal cancer staging.

Introduction: Non-Government Organization (NGO) is Non-Profit Organization founded to create social impact without looking for profit. NGOs are generally funded through charitable donations, however, many of those sources of funds have dried up. For sustainability, NGOs need to find ways to enhance their sustainability, diversify their income source and become less dependent on donors. This research will study Global Peace Foundation Indonesia using Gap Analysis to find how to transform an NGO into a Social Enterprise and the innovation of the business model needed. Literature Review: This research benchmarks Fowler’s steps of social enterprise, Ann Mei Chang’s hybrid organization, and Burkett’s social business model. Research Methodology: This research collects primary and secondary data through interviews, FGD, and desk research. The data obtained data from the collection methods will be processed and analyzed with a qualitative approach: logic model, PESTEL Analysis, and SWOT Analysis. Result and Discussion: From the logic model of Global Peace Foundation Indonesia, can be seen that some projects can potentially be transformed into a social enterprise, and the nearest industry to those projects are Tourism Industry. Continuing the logic model analysis, PESTEL Analysis was done, and the result showed some positive opportunity in the tourism industry that relate to what Global Peace Foundation Indonesia value. As there’s a positive opportunity, SWOT Analysis was used to find the strategies to implement. Those Analyses were used to produce the Value Proposition Canvas and Social Business Model of Global Peace Foundation Indonesia. Conclusion and Recommendation: Fowler’s steps of Social Enterprise are slightly different from the transforming steps of Global Peace Foundation Indonesia. This research can be used by other field affiliates of the Global Peace Foundation and other NGOs who want to transform into social enterprises too. Future research can focus on the assigning human resource and leadership to the transformation process.

Published: July 2023

Propõe-se com este trabalho uma reflexão sobre o modo como as populações indígenas têm se colocado enquanto sujeitos históricos diante daqueles que se esforçam pela manutenção de seu silenciamento e objetivação. Os dados foram gerados no evento “Direitos indígenas e a atual conjuntura política brasileira”, promovido pela Associação dos Estudantes Indígenas da Universidade Federal de Santa Catarina (AEIUFSC), organizado imediatamente após a confirmação de Jair Bolsonaro como presidente do Brasil. A partir dos discursos do candidato eleito cujas afirmações evidenciam uma ameaça aos povos indígenas no que diz respeito principalmente ao direito à demarcação de suas terras, estudantes indígenas da UFSC sentiram a emergente necessidade de problematizar as situações a que poderiam vir a ser expostos. A terra, para esses povos, é local sagrado e onde as práticas linguístico-culturais são realizadas, portanto, essas discussões se fazem urgentemente necessárias.
The Faces of Hacktivism by the Anonymous Collective in the Context of Russian War Against Ukraine. Comparison Between 2014 and 2022
Authors: Betlej Alina
Published: July 2023

Hacktivism is a social phenomena which evokes different social assessments. The definitions of a term differ in many respects. This theoretical model of hacktivism has not yet been implemented into an empirical strategy for sociological research. The paper describes the the main initiatives taken by Anonymous collective during the 2014 conflict in Ukraine, which is considered by many researchers to be the first stage of preparation for the war triggered by Russia in 2022. Author analyses the collective’s activity in 2022, after the war started, in order to identify similarities and differences in the creation of information messages about the situation. The comparative analysis covers information published in Anonymous’ tweets and selected online news services. She asks the question about the possible consequences of Anonymous actions in the open cyber field for the social moods around the world. To what extent these media messages and their construction have reflected the social perception and/or social attitudes towards Russia’s aggression? The theoretic explorations were embedded mainly on two methods: criticism of writing and the analytical and comparative one.
The Moderating Role of Visitors’ Nationality on the Relationship between Service Quality and Behavioural intentions in Star Rated Game Lodges
Authors: Njagi Caroline , Mutinda Rayviscic , Mwangi Benson
Published: July 2023

Purpose: Tourists from different nationalities manifest differing cultural values that influence service quality perceptions that subsequently elicit their behavioural intentions. However, the moderating role of nationality in the relationship between service quality and behavioural intention from the game lodges’ perspective has not been sufficiently examined. Hence, this study aims to examine the moderating role of nationality on the relationship between service quality and behavioural intentions.

Methodology: The study adopted a cross- section survey and data was collected using structured questionnaires from 312 tourists from 29 different nationalities residing in star rated game lodges at Masai Mara national reserve and its conservancies in Kenya. Data were analyzed using both descriptive and inferential statistics. To test whether or not the nationality of the respondents influenced the study hypothesis, structural equation modelling (SEM) and a multi-group analysis approach were conducted. Data was presented in the form of tables and figures.

Findings: The study found that there was a positive and significant relationship between service quality and behavioural intentions. Similarly, the results indicated that the tourists’ nationality moderates the relation between service quality and behavioural intentions.

Recommendations: The study findings contribute to the body of knowledge in service marketing and more specifically on the role of customers’ nationality on service quality perceptions and behavioural intentions. The research findings provide a strong foundation for policy support in governance to the tourism stakeholders for the growth of different tourism markets in Kenya. Further, the study findings inform the stakeholders on the nature of service quality needed based on tourists’ cultural differences to maximise the potential from the existing and emerging tourism market.

Published: July 2023

The importance of public safety and the responsibility of the government and its citizens in ensuring it. The study highlights the vulnerabilities of seaports and the challenges faced in securing them. The Philippine Ports Authority (PPA) is tasked with ensuring the safety and security of cargo, personnel, and passengers in PPA-managed ports in the country, including the Ozamiz City Port. The Ozamiz City Port security personnel are responsible for maintaining a safe and secure environment in the port, including preventing crimes such as theft, unauthorized entry, and drug trafficking. The research aims to understand the daily experiences of security personnel in Ozamiz City Port and collect data on the methods and strategies employed to perform their duties and responsibilities. This study utilized the qualitative research approach, specifically the phenomenological design. The process of analyzing the data to come up with a meaningful theme follows Moustakas’ transcendental phenomenology. This approach focuses on the wholeness of experiences and searches for the essence of experiences; it attempts to eliminate everything that represents a prejudgment or presupposition. The researchers recommend training port security personnel on effective communication and conflict resolution techniques, assisting travelers, and creating a supportive environment. The study highlights the significance of having a positive mindset and resilience in dealing with challenges in the workplace.

In the Philippines, the National Service Training Program (NSTP) is a law that must be followed. This study explored the perception of senior high school students towards the implementation of the ROTC. It was conducted at one of the higher educational institutions in Ozamiz City, situated in Misamis Occidental in the Northern part of Mindanao during the school year 2022-2023. The study utilized the descriptive-correlational research design. Two hundred and fifty-six respondents were included in this research study; they were chosen at random by the researchers to participate in the survey using random stratified sampling. The researchers used adapted research questionnaires. The statistical tools used were mean and standard deviation and t-test. The quantitative study results revealed that the perception of senior high students towards the implementation of ROTC showed very high in terms of physical capabilities and psychological capabilities. And only high for extent knowledge and attitude. This only shows that the students tend to give more importance to the aspect of physical and psychological capabilities compared to having extent knowledge and attitude in the implementation of ROTC. Moreover, it shows that there is a significant relationship between physical and psychological capabilities toward attitude. But for extent knowledge and attitude, it has been shown that there is no significant relationship between them. It signifies that physical and psychological capabilities can impact the attitude of the students compared to the extent knowledge which shows that the students will be more focused or will give more attention to their academics than ROTC. The researchers recommend that in terms of administrative support, such as office, training ground, logistics, funding, and registration of grades and graduates, schools should continuously examine and enhance the ROTC program as part of their annual program.

Authors: U Amaleshwari , R Jeevitha
Published: July 2023

The idea of a circular economy is becoming more popular in academia, business, and public policy. A circular economy is an alternative economic model that reduces waste, pollution, and the lack of resources. On the other hand, numerous studies have been studied under Entrepreneurial Orientation (EO). The dimensions of EO, such as risk-taking, innovativeness and proactivity, are studied to draw a relationship with Circular Practices. The literature study examined the theories' ideas and ways of thinking about them. It also gave a framework that pointed out the problems and the research gaps. The research design comprises of developing a hypothetical model with Entrepreneurial Orientation as the exogenous variable to test the endogenous variable of Firms Performance. In addition, Circular Practice targets Performance as a mediating variable. The methodology used in this study is quantitative that contains a random sample of Entrepreneurs in Tamil Nadu, India. The questionnaire is suggested for collecting and analysing data with SPSS version 18.0 and Partial Least Squares Structural Equation Modelling (PLS-SEM) 3.0.

The Role of Religion in Shaping Gender Norms and Attitudes: A Case Study of Tanzania
Authors: Huberman Philomena
Published: July 2023

Purpose: The purpose of this study was to investigate the role of religion in the shaping of gender norms and attitudes in the Tanzanian culture.

Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.

Findings: The findings revealed that there exists a contextual and methodological gap relating to the role of religion in the shaping of gender norms and attitudes.

Unique Contribution to Theory, Practice and Policy: The Social Constructionism theory, Symbolic Interactionism theory and the Intersectionality model may be used to anchor future studies on the role of religion in the shaping of gender norms and attitudes. Religious beliefs, teachings, and practices have a profound influence on societal expectations, reinforcing traditional gender roles and contributing to the perpetuation of gender inequalities. The findings highlight the complex interplay between religion and gender, with religious affiliation often associated with more conservative gender attitudes and the acceptance of gender-based violence. Recommendations drawn from the study include the promotion of gender sensitive religious education, engaging religious leaders and institutions, fostering interfaith dialogues, strengthening women’s empowerment programs, supporting grassroots initiates amongst others.
“Sempre ajuntando o governo espiritual com o temporal”: os escritos programáticos da Missão do Maranhão (século XVII)
Authors: Arenz Karl Heinz
Published: July 2023

Fundada oficialmente em 1639, a Missão da Companhia de Jesus no Estado do Maranhão e Grão-Pará levou mais de meio século para se consolidar. Nesse processo, diversos escritos de conteúdo programático, redigidos ou inspirados pelos padres Luís Figueira, Antônio Vieira e João Felipe Bettendorff, foram de fundamental importância. Embora escritos em contextos diferentes, os textos (um memorial, um regulamento interno e uma lei régia) reclamam a “dupla administração” (espiritual e temporal) dos missionários inacianos sobre os aldeamentos na região amazônica. A análise desses escritos possibilita compreender a organização da vasta rede de missões, tanto no que diz respeito à mediação cultural que ocorreu internamente quanto no que se refere à sua função coestruturante para a formação da sociedade regional e, de forma mais ampla, do projeto colonial na Amazônia portuguesa no século XVII.

Peat composes of organic matter and easily drying out during the dry season. This situation will result in a smouldering fire in peat swamp forest especially with the help of El-Nino phenomenon and eventually will destroy home for endangered species such as Orangutan. It is important in order to study the effect of forest fire on peat thermal properties. The study was conducted in Binsuluk Forest Reserve, Sabah, Malaysia, The aims of this study were to measure the heat of content and burning time of peat at a different level and to find the relationship of the heat of content in Binsuluk Forest Reserve. Samples of burnt peat were taken using an auger at 1.5 m, 2.0 m, 2.5 m and 3.0 m depths. The peat samples were tested for heat of content (MJ Kg-1) and burning time (minutes). Results shown that peat has a higher heat of content at a depth of 3.0 m with 51.652.07 MJ Kg-1 and lower heat of content at 2.5 m depth with 49.600.46 MJ Kg-1. Burnt peat takes longer time recorded at 3.0 m peat depth with mean value of 127.201.88 minutes and the shorter time recorded at the depth of 1.5 m with mean 101.400.51 minutes. Thus, these data suggest that increases in the heat of content of the peat can increase the time for the peat to completely burnt. The heat content and burning time were perhaps influenced by the moisture content of the peat in Binsuluk Forest Reserve with range of moisture content between 209.880.18 % to 1013.511.39 % . The information on thermal properties of peat in Sabah is important for the forest managers and researchers to get an idea of the impact of forest fire on peat and can create better management on the peat swamp forest area.

Published: July 2023

The demand for chitosan polymer in domestic and industrial use is increasingly rising. The applications are widely used in the fields of nutrition, cosmetics, biomedical, pharmaceutical, water treatment and agriculture. Normally, the preparation of chitin comes from a bio-waste source and requires three chemical processes including demineralisation, deproteinisation, and discolouration. Meanwhile, the preparation of chitosan from chitin is through the process of deacetylation. The production of chitosan and its derivatives have covered various fields, including synthetic polymers. It has also become a medium and alternative material helping to solve many problems including being able to save time, cost and energy in the production of a material. Then, there will be a positive impact on environmental sustainability and biomedical engineering. The chitin derivatives resulting from deacetylation of chitosan are also flexible enough to be lysosomal enzymes, which can be used as carriers of active drug substances in the body system. Various efforts and research have been carried out on the development of chitosan-based polymeric materials, in particular organic polymers. Chitosanbased polymers can be used as an alternative to replace petroleum and natural gas resources. Besides, it is easy to dispose of, degrades quickly, has a short shelf life and is environmentally friendly. It is proven as many previous reports and studies on the synthesis, characteristics and use of these polymers around the world. The purpose of this review is to explain the properties, methods of preparation and use of chitin, chitosan and its derivatives.
