Abstract

OBJECTIVE
To evaluate the surgical technique and subsequent clinical observations (reproductive and ultrasound findings) of left unilateral ovariectomy in 3 species of Potamotrygon rays—Potamotrygon castexi, Potamotrygon leopoldi, and Potamotrygon motoro—for reproductive management.

ANIMALS
Between 2018 and 2019, multiple Potamotrygon rays (P castexi, n = 1; P leopoldi, 1; P motoro, 6) underwent left ovariectomies to evaluate this technique for reproductive management.

PROCEDURES
At time of surgery, patient age ranged from juvenile to adult. Rays were anesthetized with MS222 buffered with sodium bicarbonate, and a left craniodorsal surgical approach was made to isolate and excise the left ovary. All rays had uneventful recoveries. Eight unilateral ovariectomized females and 6 males were combined in a mixed-species freshwater touch pool of Potamotrygon rays and teleost species.

RESULTS
In December 2020, 3 live and 1 premature autolyzed pup were noted in the habitat. The following day, the adult females were examined via ultrasound and separated from the males. Four dams were identified that produced 8 viable offspring and 4 premature abortions. A large right ovary was observed in all females, with no evidence of left ovarian tissue present via ultrasound.

CLINICAL RELEVANCE
Previous histologic evaluation of freshwater ray ovarian tissue suggests both ovaries may be functionally active yet maintain left dominance like some other elasmobranch species. This manuscript provides proof the right ovary alone can produce live offspring. Furthermore, the enlarged right ovary observed in these females suggests that removal of the left ovary may result in compensatory enlargement of the right ovary.
Environmental Compliance and Financial Performance of Shariah-Compliant Enterprises – a Data-Driven Analysis
Authors: Katterbauer Klemens , Syed Hassan , Genç Sema Yılmaz , Cleenewerck Laurent 
Published: March 2023

Purpose: Environmental, social and governance factors have gained significant traction for investors to evaluate their investment decisions and achieve higher impact investments. Societies have had a growing impact on investors to ensure that besides profitability factors, the impact on the environment, society and internal governance criteria are taken into account when allocating funds. This has led to a growing divestment from highly polluting industries and corporations that are not diverse in their workforce, or have a negative impact on the society such as using forced labor. Islamic finance encompasses the principles of Shariah law that put a strong focus on preserving the environment and support the society. Evaluating whether corporations are Shariah compliant with respect to the environment is challenging, as environmental ESG scores may not adequately represent the entire impact on the environment and the Shariah-environment compliance of corporations.

Method: This article presents a new data-driven framework for the assessment of Shariah – environmental compliance for corporations in addition to their financial performance.

Results and conclusion: An analysis based on large Islamic compliant US listed enterprises indicate strong clustering performance, and differentiation in terms of Islamic environmental compliance versus non-compliance.

Originality: The deep learning framework incorporates an unsupervised-random forest learning approach at categorizing environmental compliance while simultaneously estimating the financial performance of these corporations.

Authors: Silva Bruno Lopes , Xavier Maria Gilca Pinto , Sobral Marcos Felipe Falcão 
Published: March 2023

Purpose: This study aims to analyze the water reuse and technological innovation employed in industrial jeans processing activities in a dry region. Toritama in the Brazilian state of Pernambuco is a part of a ten-city agglomeration involved in garment production and processing. Laundries in Toritama carry out dyeing, wear, fading, and other interventions that add value to the jeans items. This activity uses large quantities of water, which is scarce in this region. Due to rising environmental concerns, the public control agencies passed legislation to ensure the laundries install a water treatment system to treat the effluents. Laundries view the requirement as a disadvantage as small non-formalized laundries are not obliged to implement reuse technology.

Method/design/approach: This study used a combined quantitative and qualitative approach to understand the complexity of the social phenomenon. The research was carried out over 2018 and 2019 in formalized laundries. The use of water in the improvement processes and the stages involved were investigated, in addition to determining the cost impact of water reuse.

Results and conclusion: the implementing an innovative water treatment system and reusing water plays a critical role in reducing environmental damage caused by industrial activities while also bringing down production costs.

Research implications: thus, the study highlights that it is possible for enterprises to gain a competitive advantage while being mindful of the environment.

Originality/value: our research fulfills the important role of clarifying the reality of organizations located in regions of peripheral economy that, despite suffering with their specificities, still have space for environmentally and socially sustainable actions.
Marketing as Seen by Different Actors: Divergences and Agreements
Authors: Bertuolo Claudemir , Minciotti Silvio Augusto 
Published: March 2023

Objective: This study investigates how teachers, managers, and consumers understand marketing and compares their answers with the literature in the area.

Theoretical framework: The perspectives about marketing are divided. On the one hand, some consider it a strategic feature with a social purpose of great importance. On the other hand, some consider it a tool for consumption’s manipulation that induces the consumers to buy what they do not need.

Method: This study consists of a mixed research method: qualitative data were collected through semi-structured interviews and addressed through content analysis. Then, in the quantitative stage, this study applied a survey based on its qualitative stage findings. The data collected were evaluated by correlation analysis.

Results and conclusion: The analyses indicate divergence between the theoretical approach to marketing and its practice. Managers’ and consumers’ definitions differ from the theoretical concepts, and the teachers’ perspectives converge with what is in the specialized literature.

Implications of the research: This topic has a significant role in organizations and society, requiring the academy to observe and debate the reality of marketing since the academy is responsible for schooling and training professionally those who teach marketing and those who take responsibility for its practical activity in companies.

Originality/value: The results contribute to the literature on the subject and the practice of marketing since it is possible to know the perspectives of the main actors involved in the theoretical construction and dissemination of marketing and those who live the application of its concepts daily.

Authors: Schreiber Dusan , Sander Silaine Carini , Vier Margarete 
Published: March 2023

Purpose: Analyze the possibility of carrying out reverse logistics in the footwear production chain, with a specific focus on the post-consumer return stage.

Theoretical background: In order to build the theoretical lens to interpret the empirical data, the authors reviewed the scientific literature that deals with waste from the footwear manufacturing process, as well as reverse logistics in the Brazilian footwear industry.

Method/design/approach: A single case study strategy was chosen, in one of the largest shoe manufacturers in Brazil, a qualitative approach, data collection through semi-structured interviews with managers of the investigated organization, directly linked to processes related to the reverse logistics of the product, in addition to a documentary survey, based on internal industry records and non-participant systematic observation.

Results and conclusion: The research results showed that the reverse logistics of footwear, in the post-consumer stage, would be feasible to be implemented, but with high initial investment and maintenance costs, which could not be supported by the industry.

Research implications: As managerial contributions, the set of empirical evidence that points to the technical viability of reverse logistics in the analyzed sector stands out, which can induce more academic research and thus benefit society.

Originality/value: This is a study that is still little explored in the scientific literature.

Published: March 2023

Purpose: To Identify and catalog the sustainable practices adopted in the Amazon Region. Sustainable development in the Amazon region is fundamental for the balance between human presence and the preservation of nature. Every productive chain that involves Amazon needs to avoid the degradation of the region.

Theoretical framework: The theoretical bases that supported the research were extracted from scientific articles indexed by SCOPUS, from books about sustainability practices in the Amazon.

Methods: We perform a Systematic Literature Review (SLR) using the PRISMA protocol. The study covered articles published in SCOPUS from 1989 to 2022. As an inclusion criterion, the articles should cover topics related to sustainable development practices in the Amazon region. The articles were cataloged by journal, study area, economic sector, and sustainability practices.

Results and conclusions: Researchers from Latin America, mainly from Brazil, are the ones who are most dedicated to studying sustainable practices and actions in the Amazon region. The studies indicate a connection between production activities and actions that seek and are concerned with environmental sustainability. The researcher's interest in the Brazilian Amazon forest was identified, with emphasis on studies of sustainable forest management, deforestation, the study of rubber, geographic information systems for better monitoring of the region to contribute to planning and management, and the study of environmental degradation driven by the deficiency of government management.

Research implications: The sustainable actions and practices characterized in the Amazon examined show what is being studied by the scientific community globally in the Amazon region and in which economic segments the practices of technological sustainability can be observed.

Originality/value: Expands understanding of sustainable actions and presents proposals and recommendations for studies up to 2050 in the Amazon.
