What You See is What You Get: Sustainable Tourism Practices and Behavioral Intention in Ecotourism of Bongabon, Nueva Ecija, Philippines
Authors: Dela Cruz Donelyne , Cabiles Desirie , Cerissa Velasco Leah , Hyde Dela Cruz Glenn
Published: September 2024

The study aimed to assess the sustainable tourism practices and behavioral intention among tourists in Camp Paraiso Hotel and Resort in Bongabon, Nueva Ecija. This study used the three dimensions of sustainable development by the Food and Agriculture Organization (2023) such as economic aspect, social aspect and environmental aspect. The behavioral intention variable was patterned after the study of Borbon et. al 2022 entitled “Tourist Behavioral Intention in Visiting Tourist Attraction in Batangas Province” which includes willingness to pay more, intention to recommend, revisit intention and loyalty.The researchers employed convenience sampling, involving 80 respondents who were tourists at Camp Paraiso in Bongabon, Nueva Ecija. The study utilized Likert-scale questionnaires and applied statistical treatments such as ranking, frequency and percentage analysis, weighted mean calculation, t-tests, and Pearson-R correlation for data analysis. This study adopted a quantitative descriptive correlational research approach. The majority of the respondents were male, and most tourists were from within Nueva Ecija, with many visiting Camp Paraiso only once or twice. The findings indicate that tourists strongly agree the sustainable practices at Camp Paraiso, suggesting high adherence to sustainability which include economic aspect (3.51), social aspect (3.52) and environmental aspect (3.55). While the study found areas for improvement in sustainable practices and overall sustainable tourism development, enhancing indicators that received strong agreement from tourists is recommended. Analysis of demographic profiles revealed no significant differences in perceptions of sustainability aspects (economic, social, environmental) based on sex. Similarly, there were no significant differences between types of tourists concerning economic aspect and environmental aspects, but there was a notable difference in the social aspect. Age and frequency of visits did not significantly correlate with tourists’ assessment of sustainable practices. Overall, the study concluded a significant relationship between Camp Paraiso’s sustainable practices in terms of economic, social and environmental (r value = 0.00001), and tourists’ behavioral intentions. The researchers proposed an action plan to enhance sustainable tourism practices specifically at Camp Paraiso.
Western Military Expatriates in the Armed Forces of the UAE
Authors: Yates Athol
Published: September 2024

Today, the United Arab Emirates (UAE) Armed Forces is recognised as the most proficient military set-up in the Arab world, recently engaged in operations in Afghanistan, Libya and Yemen, and in the fight against ISIS. This book examines a pivotal component in how the UAE built such effectiveness: Western military professionals embedded in the Emirati forces. Some of these expatriates have commanded major military formations, others served as high-ranking staff, piloted front-line aircraft, developed and delivered training, or advised senior Emirati officers. The first such individuals arrived in 1965, when they were engaged to establish the state’s initial professional military force. Expatriates have since served continuously to the present day. This volume traces their history through 14 case studies, covering the period between 1965 and 2023. It offers a comprehensive picture of the expatriates’ backgrounds, the rationale behind their recruitment, and how they have been utilized. This information provides the foundation for the book’s key research question: to what degree and how have such individuals helped to generate a sustained military advantage for the Emirati military? The implications arising from this study are important, particularly for the UAE as it contemplates the potential replacement or phasing out of Western expatriates. They are equally consequential for Western defence policy-makers seeking innovative ways to develop the capabilities of friendly advanced nations, and for the more than a thousand expatriates currently serving in the Gulf who aspire to increase their influence.
On the status and occurrence of the foraminiferal genera Nubecularia and Sinzowella in the late Middle Miocene of the Paratethys Sea
Authors: Piller Werner E. , Harzhauser Mathias
Published: September 2024

“Nubecularia bioherms” represent unique foraminifera dominated buildups which are restricted to the late Middle Miocene (late Serravallian) of the Paratethys. They occur in the Central Paratethys in the late Sarmatian and in the Eastern Paratethys in the Volhynian–Bessarabian, both regional stages of the respective Paratethyan areas. The generic assignment of the main constituent of the bioherms changed in time from Spirorbis to Nubecularia and Sinzowella. No clear diff erential diagnosis has been provided for the establishment of the genus Sinzowella by Cushman (1933) and the diff erence between both porcelaneous taxa was reported to be the agglutination of foreign particles in Nubecularia (Loeblich and Tappan 1964, 1987). Since in studied Central Paratethyan material agglutinated particles occur frequently in the test wall a separation of Sinzowella from Nubecularia is not justifi ed based on this character and Sinzowella is considered synonymous with Nubecularia. At the species level the situation is even more confusing since a variety of species (nodulus, novorossica, caespitosa), subspecies or/and “types” (e.g., nodulus, solitaria, deformis) have been described. All these taxa are considered to be subjective junior synonyms of Nubecularia nodulus which is the only Nubecularia species in the Central Paratethys since all described morphotypes co-occur even in a single rock thin section.

O Olhar de quem esteve lá: imagem e etnografia
Authors: Bittencourt Pires Chaves Andréa
Published: September 2024

O presente texto propõe uma discussão sobre o uso da imagem no trabalho de campo etnográfico. Para tanto, foi necessário, primeiramente, conceituar a antropologia como ciência discorrendo sobre o histórico de sua formação científica e o trabalho de campo etnográfico enfatizando o uso da fotografia como recurso inerente a coleta de dados. Por conseguinte, o enfoque foi direcionado para o debate da fotografia em uma pesquisa etnográfica no interior da Amazônia no início dos anos de 1990 desenvolvida em um Projeto de Pesquisa denominado Controle Ambiental da Garimpagem no Rio Tapajós. O relato desta experiência de pesquisa etnográfica apresenta uma relevância para a reflexão da imagem como elemento importante na relação entre o pesquisador, o pesquisado e o leitor da pesquisa. Neste caso, a imagem atua como mecanismo de aproximação entre os componentes desta tríade (pesquisador, pesquisa e leitor) na experiência vivenciada no campo de pesquisa. O leitor que não esteve lá visualiza o recorte feito por quem lá esteve. Assim como, a imagem permite uma relação de confiança e troca entre o pesquisador e o pesquisado.

“A casa pode ser dele, mas o lar é meu”: crossdressing, relações familiares, conflitos e cuidado
Authors: Vencato Anna Paula
Published: September 2024

Este trabalho discute dados coletados em pesquisa etnográfica com mulheres que se identificam como “esposas” ou “S/O’s” de homens que “praticam crossdressing”. É, ainda, um desdobramento de pesquisa anterior, sobre como homens que se identificam como crossdressers negociavam esta prática em suas vidas cotidianas. Busco refletir sobre como o crossdressing de seus companheiros impacta suas vidas privadas, suas sociabilidades, suas relações afetivo-sexuais/conjugal, bem como as relações familiares mais amplas. Importa compreender como tensões relativas às convenções sobre gênero e sexualidade e o manejo de segredo impactam essas relações conjugais/familiares e a questão do cuidado, assim como por vezes se desdobram em opressões/violências e interferem na dinâmica dos afetos e do companheirismo, implicando por vezes em renegociações ou rupturas.

Published: September 2024

Education is a fundamental right that should be accessible to all members of the society. However, one of the major contemporary social problem confronting most African Countries in the world is the Teenage Pregnancy. Teenage pregnancy limits girls’ access to higher education in developed and developing countries. Teenage parenthood and pregnancy during adolescence are risk factors for school dropout. Despite the numerous interventions put in place to address the challenge of teenage pregnancy among secondary school students, this problem continues witnessed in Kenyan secondary schools, particularly in Tharaka Nithi County. The low effectiveness in combating teenage pregnancy can be attributed to many factors among them parental influence. Therefore, the purpose of this study was to investigate parental influence on teenage pregnancy among secondary school students in Tharaka Nithi County. Descriptive research design adopted for the study. Data gathered from 15 secondary schools based on school categories using the Cluster sampling procedure. Clusters based on the school national ranking. The target population was 11,936 form three students in Public and Private secondary in schools in Tharaka Nithi, County. A sample size of 410 respondents comprising 30 teachers, and 380 students (300 girls and 80 boys) used. The instruments for data collection used were structured questionnaires and personal interviews. Pilot testing done in two schools in Meru County. The overall reliability coefficient of instruments using Cronbach’s alpha yielded 0.754. Data were analysis by use of descriptive statistics (frequencies, percentages, and standard deviation) and inferential statistics (Chi-square). Data analysis undertaken with the help of the Statistical package for Social Sciences (SPSS) version 26.0 software. The study established that there is a strong positive significant influence of parental influence on teenage pregnancy among secondary school students in Tharaka Nithi County, Kenya. The study recommends that the National and Tharaka Nithi county governments should engage parents in workshops to train them on comprehensive sex education and provide them with educational materials and guidelines. The research findings of the present study can shed light on secondary schools administrators, the Ministry of education policymakers, teachers, parents, and other stakeholders on teenage pregnancy among secondary schools in Tharaka Nithi County, Kenya.

Green Financing for Sustainable Development in Infrastructure Projects in Kenya
Authors: Amolo, PhD Dr. Amolo Elvis Juma
Published: September 2024

Transitioning into a decarbonized economy requires an unprecedented level of new capital investment, particularly in the form of green finance. Market and regulatory trends indicate that there is an increased interest in green and sustainable finance among investors and policymakers. However, capital mobilization for green investments has been constrained by microeconomic obstacles including maturity mismatches between long-term green investments; the typically short-term time horizons of investors and disintegrated financial and environmental policy approaches. It’s against this backdrop that the study intended to assess the green finance trends, green finance instruments and the challenges on green finance adoption.The study adopted desk review also known as Meta-analysis method to extract information concerning green finance trends, instruments and adoption challenges. The study established that to achieve sustainable development goals (SDGs), its necessary to open-up green projects and scale up the financing of investments that provide environmental benefits through innovative financial instruments and new policies such as green bonds, green banks, carbon market instruments, fiscal policy, green central banking, financial technologies and community-based green funds. However, Financial institutions show more interest in fossil fuel projects than green projects because of the low returns and risks associated with green investment compared to brown investment. To reduce the risk of green investment and increase the rate of return to the investors, the creation of green credit guarantee schemes and tax return on revenue generated from the green energy spillover effect is necessary. In conclusion green finance market is well structured in developed economies unlike developing economies due to underdeveloped capital markets, regulatory gaps and unstandardized green taxonomy.Thus the study recommends the development of green finance database and incorporation of green agenda in public policy institutions’ mandates and procurement;Standardization and information disclosure regarding Green investment risks, green taxonomy and commoditization of environmental factors into tradable assets; Raising awareness; Offering tax incentive on green projects; Developing Carbon Capital Markets; Stock Trading of Green finance products; Strengthen the social responsibilities of investors and Technology adoption.

Published: September 2024

Background: Humanitarian missions and mobile camp surgeries have pivotal roles in cataract surgery in areas with limited resources. Ocular biometry is an important preoperative evaluation tool for cataract surgery candidates. Herein, we report the distributions of ocular biometric values among cataract surgery candidates in camp settings in southern Nigeria.
Methods: In this cross-sectional study, we retrieved data from consecutive patients scheduled for cataract surgery. All patients underwent a full ophthalmic examination using a slit-lamp biomicroscope. Age, sex, and preoperative biometric values, including anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), and axial length (AL), together with intraocular lens (IOL) power, were documented. Biometric values were obtained using A-mode ultrasonography.
Results: Records of 567 patients with a mean (standard deviation) age of 66.0 (13.4) years revealed a male-to-female sex ratio of 1:1.24. Most participants were in the 66–70-year age group. Mean IOL power was significantly different between males and females (P < 0.001). However, the biometric values were comparable between sexes (all P > 0.05). There were significant differences in the mean IOL power (P < 0.001) and ACD (P < 0.05) between the age groups, indicating a decrease in ACD with age. However, the other biometric parameters were comparable between the age groups (all P > 0.05). ACD had a significant weak negative correlation with LT (r = - 0.16; P < 0.001) and IOL power (r = - 0.22; P < 0.001) and a positive correlation with AL (r = + 0.24; P < 0.001). LT had a significant weak negative correlation with VCD (r = - 0.16; P < 0.001) and a positive correlation with AL (r = + 0.09; P < 0.05). VCD had significant moderate positive and negative correlations with AL (r = + 0.39; P < 0.001) and IOL power (r = - 0.34; P < 0.001), respectively. AL had a significant strong negative correlation with IOL power (r = - 0.78; P < 0.001).
Conclusions: This study presents the mean distributions of ocular biometric parameters among cataract surgery candidates in camp settings in southern Nigeria. Age and sex were important determinants of IOL power and should be considered when planning eye camp supplies. AL had a strong inverse correlation with IOL power. Further multicenter national studies are required to verify these preliminary findings.

Background: Band keratopathy is a chronic, degenerative corneal disease resulting from gradual calcium deposition in the superficial cornea. Herein, we report the spectrum of causes, treatment outcomes, and recurrence rates of band keratopathy at a tertiary referral center throughout one decade.
Methods: This retrospective study included patients with clinical diagnoses of band keratopathy who were treated with combined ethylenediaminetetraacetic acid (EDTA) and superficial keratectomy with or without amniotic membrane transplantation (AMT). Patient medical records were reviewed, and detailed demographic and ophthalmological data, such as baseline and last follow-up best-corrected distance visual acuity (BCDVA), ocular or medical comorbidities, type of intervention, postoperative follow-up duration, relevant complications, and recurrence were recorded.
Results: A total of 32 eyes of 29 patients with 3 (10.3%) bilateral and 26 (89.7%) unilateral cases of treatment-requiring bank keratopathy were included. The mean (standard deviation [SD]) (range) age was 39.4 (22.4) (2–74) years, and most patients were female. The most common secondary cause was previous vitreoretinal surgery with silicone oil tamponade (15.6%); however, idiopathic cases were the most common (18.8%). Systemic comorbidities were present in 27.6% of patients, consisting of hypertension, diabetes mellitus, epilepsy, coronary artery disease, Behcet’s disease, and juvenile idiopathic arthritis; however, none of the patients had systemic diseases associated with hypercalcemia. Two of the 3 patients with bilateral involvement had chronic uveitis secondary to systemic rheumatological disease. The mean (SD) follow-up duration was 5.6 (4.0) years, and no serious postoperative complications occurred. The mean (SD) baseline and final BCDVA in logarithm of the minimum angle of resolution (logMAR) were 1.98 (1.0) and 1.7 (1.0), respectively (P > 0.05). Combined EDTA chelation and superficial keratectomy with and without AMT were performed in 12.5% and 87.5% of eyes, respectively. Recurrence was observed in 37.5% of eyes within the mean (SD) (range) follow-up of 9.4 (9.1) (1–32) months. Seven of the 12 eyes with recurrence underwent re-EDTA chelation combined with superficial keratectomy and AMT; however, 5 patients managed conservatively.
Conclusions: In this study, band keratopathy requiring intervention more commonly affected female individuals and was unilateral. Most cases were idiopathic. Systemic comorbidities were present in approximately one-third of cases. Managing band keratopathy using a combination of EDTA chelation and superficial keratectomy with or without AMT could be a potential treatment modality. Further large-scale studies are required to provide robust conclusions regarding the efficacy and safety of this management approach.

O presente resumo é mostrar a importância do Estágio em Ensino de Biologia 2, onde os alunos da disciplina começam com a introdução à docência, visando um futuro profissional, assim como métodos de ensino de Biologia, que em muitas escolas possuem o tipo de ensino tradicional (em que os alunos são passivos no processo de aprendizagem, tendo o professor como fonte única de transmissão do conhecimento) e serão mostrados métodos de ensino alternativos ao ensino tradicional. O estágio baseou-se em uma escola particular no Recife, localizada no bairro do Ipsep, a referida escola é uma das maiores do bairro, tendo uma grande parcela de estudantes de próprio bairro e também das redondezas, a escola preocupa- se muito com o ensino de qualidade e com a disciplina (pois os relatos de maus comportamentos e de pichações são quase nulos). A escola também fez uma parceria com a editora Moderna para ter-se os melhores materiais como lousas digitais e livros. Os alunos são muito proativos, gostam muito de aprender coisas novas (que estão relacionadas com o assunto), são interessados e gostam de novidades! O segundo estágio em ensino de biologia mostrou como resume-se a educação e também mostrou as diversas possibilidades que o ensino têm e também o que pode-se melhorar no ensino (foi utilizado o recurso de metodologias ativas no ensino, em que os alunos são totalmente ativos no processo de ensino/aprendizagem, foi utilizado no 6° e 9° anos o recurso, pois possui um coeficiente de aprendizagem muito alto em relação à uma aula totalmente expositiva, no caso do 6° ano, foi demonstrado o experimento da anilina no copo, que teve como assuntos a atmosfera da terra e no caso do 9° ano foi mostrado com uma bola de tênis como ocorre o processo energético dos corpos, evidenciando assim a Energia Potencial Gravitacional e Energia Conservada. O Estágio propiciou também a observação da gestão escolar, a escola utiliza a gestão democrática, pois todos do ambiente interno (funcionários de limpeza e professores) e do externo (comunidade extraescolar) a escola, a cada início de semestre, faz um panorama dos altos e baixos do ano anterior para que os erros cometidos no ano sejam concertados e implantados no próximo ano letivo. O colégio preocupa-se com o bem-estar dos alunos, tanto que os estudantes possuem um acompanhamento pela direção quando as notas não são satisfatórias que em seguida será comunicado aos pais ou/e responsáveis.

O Estágio Curricular Supervisionado, fundamental na formação de docentes nos cursos de licenciatura é um método de aprendizagem necessário a um profissional que deseja atuar e precisa estar preparado para encarar os desafios de uma carreira. Os professores têm convivido com o discurso constante da necessidade de atualização permanente. O objetivo deste resumo é relatar as experiências vivenciadas no Estágio de Ensino em Biologia 4 da Universidade Federal de Pernambuco na escola Estadual Professora Generosa Gil Perez (Paulista-PE). Foram utilizadas como estratégias didáticas, jogos pedagógicos como o dominó ecológico, o bingo dos vermes e o baralho do conhecimento para a Genética Humana. Tais estratégias didáticas foram aplicadas nas turmas do 6º ano do Ensino Fundamental II, no 2º ano do Ensino Médio e 3º ano do Ensino de Jovens e adultos respectivamente. Os jogos que envolvem peças com imagens e definições para serem relacionadas com o assunto Introdução a Ecologia, foi denominado como dominó ecológico. O bingo dos vermes foi realizado com os filos Platelmintos e Nematelmintos com cartelas que contém definições e o professor fazendo perguntas com relacionado com o tema. Nas cartelas há definições variadas com outros assuntos para o aluno identificar a resposta correta com o conteúdo proposto. O baralho do conhecimento para a Genética Humana, envolve cartas com definições e outras com termos com teoria, devem estar relacionadas com o conteúdo. Estes jogos pedagógicos, foram utilizados para o ensino de ciências e biologia. A partir do uso dos instrumentos didáticos, foi possível observar que os alunos se empenharam para a realização das atividades propostas, sendo um momento de bastante interação e entusiasmo. A atividade foi motivadora, levando-os ao aprendizado de conceitos científicos e exemplificações, proporcionando uma aproximação com a ciência. Percebe-se que através destas atividades educativas, como jogos pedagógicos, pode-se aproximar o aluno do conhecimento.
