The Great Barrier Reef Marine Park: Conflict and Consensus in Marine Conservation
Authors: Woodley Simon
Published: November 2024

When it was formed in 1975, the Great Barrier Reef Marine Park (GBRMP) was a unique example of a multiple use marine protected area (MPA). Today it is often used as a model for other countries looking to establish similar MPAs. This case study looks at the historical context of the GBR; the physical, biological, social, economic, and cultural settings; and the processes of implementing and managing the park (including conflict between federal and state power). A focus is given to the key issues affecting zoning implementation, such as the balancing of interests for indigenous interests, fisheries, and tourism. The case study also reflects on management lessons learned and looks ahead to future problems the GBRMP faces.
Forest Ecosystem Management: A New Paradigm for Preserving Forest Biodiversity
Authors: McGee Gregory
Published: November 2024

Forest ecologists have developed a more complete understanding of the ecological impacts of traditional forest management practices and the need to integrate knowledge of structure-biodiversity linkage into modern management techniques. This has led to the development of forest ecosystem management (FEM), which has been adapted by various public and private land managers, in hopes to improve the ecological conditions of the world’s forests. This module provides a review of the history of forest management and silviculture systems leading to the developing of FEM. In addition, the process of adapting and developing FEM is explored through a case study based on northern hardwood forests in eastern North America.

En cada parte encontrará preguntas o ejercicios para facilitar la reflexión sobre el tema desarrollado.
Conservation of Vernal Pools: Lessons from State and Local Action
Authors: Calhoun Aram , Morgan Dawn
Published: November 2024

Vernal pools are seasonal local wetlands that are vital primary breeding habitat for amphibians and fairy shrimp. They are also often threatened by development and are difficult to conserve with usual regulations. This case study examines vernal pool conservation policy in Maine, particularly in the town of Falmouth. It also provides a review of U.S. history and attitude towards wetlands and takes a look at the role of federal and state protection for vernal pools. Maine has the strongest regulations for vernal pool habitats in the Northeast United States, and Falmouth leads towns in further strengthening state protections. By understanding the challenges and successes of these initiatives, students can learn more about effecting conservation on private lands for any resource or species.

Published: November 2024

Restoring wildlife populations requires locating, protecting, and connecting areas where species can thrive under both ecological and anthropological conditions. Addressing these spatial needs may be difficult, as required habitats may have been lost, fragmented, or altered prior to restoration. Changes in land use may also lead to increased human-animal interactions that impact restoration outcomes. In this exercise, students consider these issues in a case study of Florida panthers (Puma concolor coryi), a currently federally protected carnivore that has a growing population in the state of Florida, USA. Students will use Google Earth to view, manipulate, and create maps related to the growth of panther populations and related habitat needs and human interactions from the early 1990s to 2021. In doing so they will explore how stakeholders interact with each other and with panthers regarding both their hopes for species restoration and the areas they represent or occupy. Students will also consider various ways stakeholders may be engaged to provide panthers with increased protection and expanded ranges, including land acquisition, conservation easements and banking, and wildlife corridors.
Changes in Protease Activity of Ginger Rhizome during Postharvest Storage
Authors: Tsumura Kazunobu , Yamada Norihiro
Published: November 2024

It has been reported that ripe ginger rhizomes contain proteolytic enzymes. In this study, we investigated the fluctuations in protease activity from ginger rhizomes stored after harvest for the utilization of proteases. The juice from ginger rhizomes that had been stored for 4 months after harvest exhibited the highest specific protease activity. Additionally, juices with high specific protease activity could form soymilk and cow milk gels. Electrophoresis experiments revealed that the protein bands in ginger rhizome juice were degraded by the proteases contained in the juice. This degradation was prevented by adding the cysteine protease inhibitor E-64.
Beside Marriage Equality: Conversations on Supriyo
Authors: Sheikh Danish , Samuel Rupali
Published: November 2024

This case comment takes the form of an epistolary exchange between the authors as they reflect on the Indian Supreme Court’s 2023 judgment in Supriyo @ Supriya Chakraborty & Anr v Union of India, which denied the existence of a constitutional right to marriage and deferred the responsibility of legalising same-sex marriage to the legislature. Through a staged conversation, the comment explores personal subject positions, legal frameworks, and the intricate entanglements of intimacy and state recognition. The authors consider how the law leaves imprints on our bodies and, in turn, how our embodied lives reshape the law through acts of resistance and reinterpretation. The dialogue moves beyond legal critique to ask whether marriage can be queered or reimagined in ways that foster liberation. In doing so, we foreground the generative potential of conversation as a space of freedom—one that reflects the authors’ lived experiences and the ongoing struggles for queer recognition and justice.

Authors:   Danubius International University, Galati, Romania, Tanasă Florentin-Emil , Nuță Florian Marcel ,   Danubius International University, Galati, Romania
Published: November 2024

In the last 20 years, the road infrastructure in Romania has expanded considerably and affected a significant number of natural and legal persons, owners of real estate located on the expropriation corridor. According to the Rejust database, in the last 10 years, annually, on average, approximately 4,000 files were created before the courts with expropriation as their object. In this article, we propose to present the legislative framework and particularities of the evaluation process of real estate properties subject to expropriation for reasons of public utility. The importance and actuality of such a theme was generated by the very large number of cases pending before the courts as a result of the dissatisfaction of the owners of buildings subject to expropriation for public utility reasons regarding the amount of compensation values granted. Also, at the level of the courts, there is a non-uniform practice regarding the method of drawing up evaluation reports. The study aims to review the procedures related to public interest expropriation and to create the premises for future research in the field.

Authors:   Durban University of Technology, Durban, South Africa, Mvunabandi Jean Damascene
Published: November 2024

The lack of empirical evidence on key drivers of financial illiteracy among financial managers within non-governmental organisations (NGOs) sector can be the trigger of the current rate of NGOs collapsing in South Africa. Using a quantitative research strategy, this study investigated the role of financial literacy in improving the level of financial knowledge, financial skills and financial responsibility among 53 NGOs finance staff who were purposively and conveniently sampled. The respondents comprise financial managers, accountants, and senior managers and project managers. Data generated were analysed using descriptive and inferential statistics. The results of the study revealed that all the independent variables of the study correlated between .247 and .569. The findings of the study revealed that the ability to prepare a strategic business plan and the respondents’ capability to cope with their organisations’ financial shortfalls have a positive and significant relationship with their level of financial literacy. The study further found that (1) dealing with financial diversification (2) comparing their organisations’ financial performance against the financial objectives (3) writing financial objectives and (4) their ability to raise funds from different funders for their organisations have a positive and significant influence with their financial literacy. This article is the first to explore the financial literacy status among NGOs financial managers in KwaZulu-Natal (KZN). Relying on these empirical findings for the financial literacy variables. This study will fill a gap in understanding the variables identified that drive the financial literacy of NGOs financial managers. These findings will help NGOs financial managers to choose the financial literacy practices model to improve their financial knowledge, skills and responsibilities and eventually enhance the financial viability and sustainability of their entities. This study contributes to the current body of knowledge and further offer insight into constructs for measures of financial literacy among NGOs context.

This study was carried out to evaluate the effects of thermal processing techniques on the nutrient and antinutrient contents of pigeon pea (Cajanus cajan) flours. The pigeon pea seeds were sorted, cleaned and divided into five equal lots of 0.5kg each. Four lots of pigeon pea seeds were processed into blanched, boiled, roasted, and autoclaved pigeon pea flours, while the fifth lot was processed raw and used as control. The raw and thermally processed samples obtained were analysed for nutrient and antinutrient composition using standard methods. The proximate composition of the samples showed that the flours had a range of 8.61 - 11.46 % moisture, 21.13 - 23.94 % crude protein, 1.26 - 1.68 % fat, 5.12 – 6.10 % crude fibre, 1.74 – 2.97 % ash, 55.56 – 60.41 % carbohydrate and 333.45 - 342.75 kJ/100g energy, respectively. The mineral composition showed that the flours contained 86.24 – 144.72 mg/100g calcium, 137.80 – 170.33 mg/100g magnesium, 125.86 - 156.76 mg/100g potassium, 66.66 – 95.62 mg/100g sodium, 4.38 – 6.64 mg/100g iron and 130.27 – 178.29 mg/100g phosphorus, respectively. The vitamin content of the flours were 3.09 - 4.33 mg/100g ascorbic acid, 0.05 - 0.17 mg/100g thiamine, 0.03 - 0.21 mg/100g riboflavin, 0.13 - 0.28 mg/100g niacin, 3.21 - 6.25 mg/100g vitamin A and 1.10 - 2.70 mg/100g vitamin E, respectively. The antinutrient composition of the flours also showed that the levels of trypsin inhibitor, tannin, phytate, oxalate, saponin and haemagglutinin ranged from, 2.30 – 5.61 Tiu/mg, 0.81 – 1.5mg/100g, 1.12 - 4.18mg/100g, 0.48-4.01 mg/100g, 1.28 – 3.66 mg/100g and 1.30 – 7.44 Hiu/g, respectively.

Authors: Guimarães Patrik de Oliveira , Nunes Andrei Caíque Pires , Silvestre Marcela Aparecida de Moraes , Cerqueira Amanda Freitas , Romão Kethlin de Carvalho Santos
Published: November 2024

Knowledge of the pollen dispersal distance (PDD) is crucial for delimitating the collection radius of subpopulations in seed collection areas used as germplasm sources for genetic breeding, conservation, and restoration projects. Some studies have reported the PDD of trees, but these are scattered throughout the literature. Therefore, the objective of this study was to systematically review and report as many PDDs as possible found in the literature on native Brazilian tree species. In the present study, we identified the most and least studied species, temporal trends in publications, geographic distribution of studies, mating systems, and pollinator types for each species. A systematic review protocol was established, and the search criteria were improved, resulting in 543 articles. Forty-four articles contained information on native species, and 319 PDD from 41 tree species were extracted. The most investigated species for pollen dispersal were Cariniana estrellensis (Raddi) Kuntze (Jequitibá-branco) and Araucaria angustifolia (Bertol.) Kuntze (Araucária). The PDD values ranged from 9 m to 5229 m, averaging 543.9273 m. The five species with the highest average PDDs were Centrolobium tomentosum Guill. ex Benth. (Araribá), Swietenia macrophylla King (Mogno-brasileiro), Hymenaea courbaril L. (Jatobá), Dipteryx alata Vogel (Baru) and Hymenaea stigonocarpa Mart. Ex-Hayne (Jatobá do Cerrado) at 3191 m, 1472 m, 1450 m, 1215.12 m, and 1086.81 m, respectively. Theobroma cacao L. and Ilex paraguariensis A.St.-Hil. had the shortest PDDs averages at 28 m and 15.9 m, respectively. This work provides a valuable PDD database that will expand the possibilities for new research and guide projects related to seed collection, forest restoration, germplasm conservation, and genetic breeding of native Brazilian trees.

Renewable Energy and Tourism: Conflict and Compatibility Between Iceland’s Major Economic Sectors
Authors: Cook Kaelan
Published: November 2024

Both the tourism and energy sectors in Iceland are key drivers of economic growth highlighting the importance of understanding how they grow together. This review will explore the conflict and compatibility that the tourism and energy sectors have with one another. Tourism in Iceland focuses on the importance of preserving the natural beauty of the landscapes people visit which inadvertently disrupts energy development in those same areas. The dispute between the two sectors ultimately revolves around the best use of land. The energy sector has fortunately found somewhat of a middle-ground by which tourists visit the power facilities themselves for industrial sightseeing. There are initiatives in place that foster compromise between the two sectors to help shed light on the importance of the issues at hand. Ultimately, more people must understand the interplay between tourism and energy in Iceland so that policymakers can move forward in making the best decisions for the country.

SIMPLIFIED METHOD FOR ESTIMATING A DYNAMIC LOADRATING FOR ROLLING BEARINGS
Authors: Libera Michał
Published: November 2024

The method for calculating the dynamic load ratings of rolling bearings is described in the ISO 281 standard.The calculation procedure presented there requires reading appropriate values from many tables, dependingon the geometry of the bearing components. This approach makes numerical calculations and quick estimationof the dynamic load ratings for various bearing design variants difficult. Moreover, the tables are discrete(they provide selected values, e.g. for nominal bearing contact angles every 15), and intermediate values,in accordance with the commentary included in the ISO 281 standard, should be calculated using linearinterpolation. However, in reality, the parameters given in the tables are not linearly dependent on each other,which makes this interpolation inaccurate. In the context of the mentioned imperfections of the ISO 281standard, the aim of the work is to simplify the calculation procedure, adapt it to numerical applications,and replace linear interpolation with an appropriate non-linear function. The difference between the valuescalculated according to the proposed formula and the value calculated according to the ISO 281 standard is onaverage less than 0.5%.

Authors: Niedźwiedź Mateusz , Bara Marek , Korzekwa Joanna , Kaptacz Sławomir , Sowa Maciej , Olesiński Aleksander , Simka Wojciech
Published: November 2024

The article discusses the effect of Plasma Electrolytic Oxidation (PEO) on the tribological properties of oxidelayers produced on the AZ31B magnesium alloy. The layers were formed using PEO (AC+DC) in an alkalineelectrolyte with a current density of 10 A/dm. The oxidation parameters (process time, cathodic voltage) wereselected based on a research plan. The tribological properties of the samples were tested on a T-17 tester in apin-on-plate test under technically dry friction conditions, using a pin made of PEEK-HPV polymer. The testsallowed the determination of the coefficient of friction, linear wear, and changes in the mass of the sampleand pin. Profilometric measurements were also made before and after the friction process. An increase in theoxidation time and cathodic voltage led to an increase in the thickness and roughness of the oxide layer. Thesample oxidized under the highest parameters exhibited the greatest thickness, as well as the highest amplitudeand Abbott–Firestone bearing ratio parameters. It was found that with increasing process time and cathodicvoltage, the coefficient of friction (μ) and polymer pin wear increased. Sample C, which had the highestprocessing parameters, showed the best tribological properties, with a coefficient of friction of 0.253 and a linearwear of 0.057 mm. Due to friction, a significant amount of opaque tribofilm was deposited on sample C, resultingin the highest mass wear of the pin (5.33 mg) and an increase in the mass of the sample by 0.74 mg.

This is a meta-synthesis study that aims to understand, through the trajectories of black women, the characterization of the impostor phenomenon in scientific publications, based on the intersectionality between race and gender. The study was developed based on five phases, namely, Exploration, Refinement, Cross-referencing, Description and Analysis. The results indicate that most of the documents discuss issues related to black women in the job market, without discussing the specificities of the impostor phenomenon. The analysis of the documents indicates that: despite the achievements, the fight for spaces and rights continues to be constant and daily; racial and gender oppression is historical and structural, which is why it falls on specific groups. This demonstrates the importance of looking at social determinants. It is understood that it is impossible to look at the characteristics of the impostor phenomenon in black women, considering it only an individualized mental health issue, but, above all, as a historical legacy.

This research investigated the intersection between neuroscience and late literacy, focusing on how neuroscientific advances can inform and improve pedagogical practices in this context. The central problem analyzed was how neuroscience knowledge can be applied to improve literacy processes in young people and adults. The overall objective was to examine the contributions of neuroscience to the development of effective strategies for late literacy, considering the neurological specificities of this population. The methodology used was a systematic literature review, with a qualitative approach, analyzing recent publications in cognitive neuroscience, youth and adult education, and literacy methodologies. The results indicated that understanding the neural mechanisms involved in learning to read and write in adults can support more efficient pedagogical practices. Insights on neural plasticity, phonological processing, and memory strategies specific to late learners stood out. The research highlighted the importance of multisensory and contextualized approaches, considering the previous experiences of the students. The final considerations pointed to the need for greater integration between neuroscience and education in the training of literacy teachers, as well as the development of methodologies adapted to the neurocognitive particularities of young people and adults in the process of learning to read and write. Longitudinal studies were recommended to evaluate the long-term effectiveness of neuroscience-based interventions in late literacy.

Introduction: Russian aggression against Ukraine has revealed the need not only to counter direct military aggression, but also in the development of effective programs for psychological support of those soldiers who directly performed their duties on the contact line. The purpose of the article is to explore approaches to the development of psychological support programs for military personnel (on the example of Ukraine).Methods: To realize this goal, the method of content analysis of professional scientific literature and the method of comparison were used, that allowed us to trace changes in the understanding of the ways of reintegrating veterans of into society and peaceful life.Results: It was found that the inclusion of educational elements in psychological support programs will contribute to accelerate the recovery process and allow for the partial involvement of  servicemen to their rehabilitation. The main components of psychological support programs psychological support programs include individual and group psychotherapy, psychotherapeutic interventions, reintegration programs, educational activities, and accessibility of assistance. The experience of Ukraine has shown that the use of collective support and active involvement of specialists in the development and testing of reintegration programs has a positive impact.Conclusions: To further implement effective programs of psychological support and reintegration psychological support and reintegration programs, it is necessary to provide additional social guarantees to help servicemen find their place in civilian life after completing their service.

Autorzy postawili sobie w artykule zadanie przedefiniowanie rachunku Ordered Fuzzy Numbers wprowadzonego przez Witolda Kosińskiego. Przyczynkiem do zamieszczonych rozważań była ostatnia dekada badań. podczas której autorzy często musieli odpierać zarzuty kierowane przez niektórych badaczy wobec tego systemu obliczeń na liczbach rozmytych. W artykule przedefiniowano zatem sama liczbę OFN z podejścia funkcyjnego na podejście wektorowe tworząc vOFN (Vectorial Ordered Fuzzy Numbers). Autorzy przedstawili rozwiązanie problemu tzw. niewłaściwych liczb OFN, czyli liczb o niewypukłych kształtach. Rozwiązali nierozwiązany przez Kosińskiego problem porównywania liczb OFN. Zniwelowali również niezrozumiałą dla wielu badaczy cechę przyrastania stopnia wielomianów funkcji zboczy narastających i opadających, jaki miał miejsce podczas wykonywania działań iloczynu i ilorazu liczb OFN, co skutkowało krzywoliniowymi wykresami funkcji tych zboczy. Dzięki redefinicji wszystkie pozytywne właściwości OFN zostają zachowane, a niedogodności zniwelowane. Autorzy wyrażają przekonanie, że dzięki podejściu vOFN arytmetyka ta znajdzie jeszcze więcej zastosowań jako prosta, niezawodna, jednoznaczna i niezwykle łatwa w implementacji.

La inteligencia artificial ofrece grandes ventajas y beneficios a las ciencias empresariales en especial en la reducción de tiempo en varias operaciones, desde la atención al cliente, proceso de producción, hasta la elaboración de estudios e investigaciones para toma de decisiones.   También hay algunas desventajas, como la poca implementación, por los costos elevados y la posible reducción de fuentes laborales, por la automatización de procesos. Las ciencias empresariales abarcan disciplinas, incluidas economía, finanzas, ingeniería comercial, contabilidad, ingeniería en comercio internacional, derecho e incluso informática aplicada a los negocios, necearías para iniciar proyectos comerciales y administrar organizaciones desde una perspectiva integradora, global y estratégica. Las empresas que adoptan la IA, la utilizan en tres áreas primordialmente: la transformación de la empresa, la mejora en la toma de decisiones y la modernización de sistemas y procesos.  En otras palabras, la empresa puede ser más rentable, la toma de decisiones puede ser mucho más acertada y también la empresa puede modernizarse a la par del avance tecnológico.

The transcendence of wild xoconostle prickly pear species -wild or cultivated in semi arid zones- dates to its Mexican origin, historical, gastronomic, cultural and medicinal customs and potentially a product of interest for rural areas due to its demand in regional and international markets. A few studies have been carried out on climate influence and arid conditions on fruit quality and no regulations exist, which allows more competitive advantages in the market. The objective of this study was to know the impact of different characteristics of arid zones, specially on morphometric differentiation in wild xoconostle prickly pear species. The study was performed in three cardinal points, Northeastern, Southern and Western of Mezquital Valley, Hidalgo, Mexico. A total of 1,000 fruits were collected, 25 and 10 per location with four replications. The morphometric variables evaluated were fruit shape and weight, equatorial and longitudinal diameter, shell thickness, areole density, developed seed number, fruit surface color uniformity, juiciness and pulp color. Three main xoconostle variants were found geographically and identified according to the region. In the northeast, Opuntia matudae (cv. Blanco) predominates in spherical prickly pear shape; in the West, a greater O. matudae (cv. Cuaresmeño) abundance is observed with predominant characteristics from elongated to ovoid shapes; in the South, more predominant O. joconostle (burrona type) is observed with a typical elliptical fruit shape. The morphometric characteristics in fruit showed significant differences among sites (P ? 0.01); O. joconostle had higher values in quantitative variables, unlike O. matudae Blanco and Cuaresmeño. The semi-arid zone impact in Valle del Mezquital have influenced the morphometric characterization of wild xoconostle prickly pear species.
