In this study, polyvinyl alcohol (PVA)/poly[acrylic acid (AAc)-co-acrylamide (AM)] composite hydrogel was prepared by radical copolymerization in the presence of Fe³⁺ freezing-thawing method. The swelling behavior of the hydrogel was investigated. The novel synthesized hydrogel was used as an adsorbent for the removal of dyes from aqueous solutions. In this paper, methylene blue and maxilon blue 5G were selected as representative cationic dyes. In addition, adsorption isotherm models were used to describe the dye adsorption process.

The prepared composite hydrogel was characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy and UV–visible.

The prepared hydrogel exhibited excellent adsorption ability for both dyes. Various experimental conditions affecting the dye adsorption were explored to achieve maximum removal of both dyes. In addition, adsorption isotherm models were used to describe the dye adsorption process.

To the best of the author’s knowledge, synthesis of PVA/poly(AAc-co-AM) composite hydrogel in the presence of Fe³⁺ and investigation of the removal of methylene blue and maxilon blue 5G dyes is done for the first time successfully.

The case study is based on a series of in-depth interviews carried out with the owners and directors of the company. The data are complemented by documentary analysis, including descriptions of internal processes and industry information. For the teaching note, the authors opt for an exploratory study using the open-ended approach of grounded theory.

Arette^® is a Mexican family business dedicated to the production and sale of tequila, fusing the artisanal with the new in its production processes. Sales take place mostly in the European and American markets. The foreign market for tequila is very attractive but also very demanding both in terms of financial resources and time. Although the company has managed to enter this market through bars and restaurants, it has not yet managed to reach the final consumers (those who order margaritas in bars). Jaime, Eduardo and Lalo are wondering whether it might be time to invest more resources in ensuring that Arette^® is not just a brand for fine cocktails. Until now, their main promotional tool has been word of mouth, and they are not sure what their next step should be – to focus on the international or the domestic market.

The case study can be incorporated into undergraduate classes, where it could serve as part of an international marketing course, in particular, as an international sales strategy and implementation session. It can be used to teach basic concepts and their application.

This case study focuses on the decision that many small companies have to make at some point in their business strategy, which is to focus either on the international or domestic market: The objectives are as follows:

1. To identify the variables that increase or modify the demand for Tequila.

2. Compare the advantages and disadvantages of focusing on a domestic Tequila market or focusing on an international market.

3. Identify the critical variables that a small company faces if it wants to go international such as.

4. Identify if there are forms of diversification for Tequila Arette such as new markets or new products, or both.

The purpose of this study is to evaluate the quality and sensory properties of cookies produced from wheat flour using avocado puree as fat substitute.

Cookies were produced from wheat flour using avocado puree as fat substitute in ratio 0%, 25%, 50%, 75% and 100%, respectively. The formulation of margarine and avocado puree blends was done by using D-Optimal Mixture Design. In all, 20 samples were produced from each substitution level and analyses were done in triplicates to obtain mean values using standard methods. Means were separated by Duncan’s multiple range test, and significances were accepted at less than 5% confidence level (p < 0.05). Proximate and functional analyses were conducted on the flour samples, while cookie samples were subjected to proximate and sensory analyses.

The results of this study revealed that the values of loose bulk density, packed bulk density, oil absorption density, water absorption capacity, swelling power, solubility and dispersibility of the flours at p < 0.05 are 0.3–0.4 g/ml, 0.5–0.7 g/ml, 16.9%–94.0%, 39.7%–80.6%, 461.2%–618.2%, 6.0%–29.8% and 69.0%–82.8%, respectively. The moisture, protein, fat, total dietary fiber, total ash and carbohydrate contents of the cookies at p < 0.05 are 3.6%–16.7%, 6.5%–9.9%, 2.5%–19.2%, 1.7%–1.9%, 1.1%–3.0% and 65.0%–70.7%, respectively. The taste, color, crispiness, texture and overall acceptability of the cookies at p < 0.05 are 7.4–7.8, 6.9–7.5, 7.2–7.9, 7.3–7.7 and 7.4–8.3, respectively. The sensory scores showed that panelists preferred the taste, crispiness and texture of the cookies produced from wheat flour using avocado puree as fat substitute at varying proportion. The sensory characteristics of sample WF⁴ (100% avocado puree) were rated overall best in all the parameters tested followed by sample WF³ (75% avocado puree). Hence, this study established the possibility of producing cookies from wheat flour using avocado puree as fat substitute without a negative impact on the sensory characteristics and the consumers’ acceptability.

The cookies produced from this study are not meant for vegetarians because eggs were added in the formulations and recipes but could be valuable to ovo-vegetarians that may take food with eggs without restriction. The major challenge of this study was that avocados are very expensive in much of the world, so this is only suitable and viable where there is an excess of the fruit.

This study examined the use of avocado puree as fat substitute in cookie production. Effects of avocado puree on proximate composition and functionality of cookies produced from wheat flour were also determined. This approach was novel, and it will encourage the use of avocado for value-added in industrial food production.

This paper aims to explore the misuse of prescription opioids, associated consumption cultures and the emergence of “informal governing images” among young men in Nigeria.

Using a qualitative research approach involving purposive sampling: six in-depth interviews, one focus group discussion and key informant interviews with two health-care professionals using the transgressive theory approach, this paper explores consumption cultures, motivations and the resultant “informal governing images” associated with the misuse of prescription opioids among young local street high-risk users in Nigeria.

Findings show complex expressions of diverse consumption practices, such as grinding, sniffing and concoction of tramadol (TM)with other opioids. The “puff-puff pass” practice serves as induction for new users of opioids commonly accessed through street drug dealers and pharmacists sold via backdoors. Codeine mixtures with different brands of soft drinks for dilution are used to achieve a “lower high” while a concoction of different opioids, with alcohol, and spirits obtains a “higher high”. Manufacturers’ indelible colouring and bottling discourage the non-medical use of opioids. Desiring to be awake for nocturnal activities, mostly “yahoo-yahoo” (internet fraud), sexual enhancement and dosage competitions, are motivations for the non-medical use of prescription opioids. These consumption cultures create “misuse circuits”, leading to the emergence of “informal governing images” triggered by threats from formal controls.

This paper, therefore, concludes that pharmaceutical industries should also add colourings to TM and codeine just like they did in rophinol to discourage the non-medical use of prescription opioids among young people in Nigeria.

This paper concludes that rather than branding and packaging in such a way that concealability is difficult for high-risk users as the best way to discourage the non-medical consumption of prescription opioids in Nigeria, the focus should be on addressing youth poverty and unemployment and improving access to treatment for drug use disorders, instead of calling for more enforcement-based measures.

The COVID-19 outbreak has significant psychological effects because of reduced support system and social quarantine, making women the worst-hit population of shadow pandemic, i.e. domestic violence. While food shortages, unemployment and increased domestic-work burdens are the immediate effects of the lockdown, women at home have to bear its far-reaching impacts in the long term in the form of domestic abuse, making the study of the psychological impact of domestic violence against women imperative. This paper aims to identify the factors and causes responsible for domestic violence and its psychological impacts on women in different aspects. This paper further focuses on the reasons behind an escalation in psychological violence against women.

This paper is based on extrapolating data from various journal articles, Indian Government reports, newspaper articles and other printed materials that are recent, relevant and discuss domestic violence and mental stress during the COVID-19 pandemic. Researchers use Indian National Commission for Women’s (NCW) data on complaints received regarding violence against women and domestic abuse in the year 2020 and 15 journal articles that discuss domestic violence against women during the COVID-19 period in different countries to discuss social inequalities and power relations impact on women’ mental health.

The findings suggest that economic instability during the pandemic and social and cultural norms of India ignited psychological abuse against women during the pandemic. The number of monthly complaints of dowry death, dowry harassment and protection of women against domestic violence reflect on increased registered complaints in the postlockdown period in the year 2020. The number of monthly complaints received by the NCW from January 2020 to December 2020 in India represents that WhatsApp chat is a powerful tool for reporting domestic violence.

The pandemic lockdown has an adverse psychological impact on women, making them suffer from posttraumatic symptoms, substance abuse, panic attacks, depressions, hallucinations, eating disorders, self-harm, etc. This paper strives to reflect upon mitigation strategies to curb domestic violence in India.

A leader who inspires, facilitates and leads people to outperform themselves and bring phenomenal changes on an individual and social canvas is recognized as a transformational leader (TL). TL focuses on innovative methods and processes to improve the efficiency of subordinates. Experts believe that transformational leadership management is more effective than pragmatic leadership. This study focuses on the traits of a TL. Mr. Dhirendra Kumar, Managing Director of Jharcraft, who set out on a mission to lead people to revive the lost art and craft in the state of Jharkhand, India. The case highlights how Kumar's leadership style aligns with the four components of transformational leadership suggested by Bass (1985), i.e. idealized influence, intellectual stimulation, inspirational motivation and individual considerations.

The study employs a qualitative approach to comprehend the theory of transformational leadership. First of all, an in-depth analysis of transformational leadership theory was conducted using secondary data. The findings of several researchers on the basis of their contribution to the development of transformational leadership theory were analyzed. Based on this, the Bass transformational theory framework was selected. Primary data were collected by conducting interviews with Mr. Dhirendra Kumar, Managing Director of Jharcraft.

Transformational leadership is a leadership style that can inspire positive changes in those who follow. TLs are generally energetic, enthusiastic and passionate. As per Bass's transformational leadership components, Kumar challenged the status quo and imbibed creativity and skill into local artisans. Artisans were imparted training by experts from the National Institute of Fashion and Technology and provided intellectual stimulation. Kumar offered support and encouragement to individual followers. In order to foster supportive relationships, Kumar articulated a clear vision to the followers. Kumar served as a role model for followers. Because followers trust and respect the leader, they emulate this individual and internalize the individual's ideals.

This study only considered the traits portrayed by Dhirendra Kumar during Kumar's tenure as the Managing Director of Warcraft, and the data were collected at one single point in time. Future research may consider Kumar's entire service journey and study factors that influenced his role as a TL.

Students will be able to learn and understand how a TL can bring positive change at the grassroots level.

This case focuses on how a TL's efforts led to the societal upliftment of poor people and made them capable.

Given the importance of transformational leadership in today's organizational context, this study builds a knowledge base to understand factors for transformational leadership and traits exhibited by TLs.

Tourism acts as a stimulant in rural poverty reduction and inclusive socioeconomic development. Sustainable tourism can significantly contribute to the economic diversification and local economic development of rural areas with its ability to create jobs and encourage infrastructural development focusing on preserving the environment, culture and indigenous groups. The detrimental effects of tourism on the economy, society and culture have shifted attention to sustainable travel. As a result, terms like ‘tribal tourism’, ‘ecotourism’ and ‘sustainable tourism’ have become popular. Inclusive engagement is a crucial agenda item in future tourism development and a major concern of many international organisations, including the United Nations. This chapter focuses on exploring the tribal communities and their involvement in sustainable tourism initiatives with an overarching focus on the role of the indigenous community and their skill sets in creating sustainable livelihoods through tribal tourism. Apart from creating direct and indirect employment opportunities, tribal tourism will support the growth of locally produced goods and have significant multiplier effects as capability-building initiatives will give impetus to the community's socioeconomic development.

Additionally, the sector offers notable advancements in the development of the tribal region. Tribal tourism will help people comprehend the significance of the ecosystem, local biodiversity and emission control activities on a deeper level (Thanikkad & Saleem, 2021). This chapter explores the indigenous tribes of Kerala and their ethnic skill sets, capabilities and means of livelihood. Further, the discussion on how the tourism domain promotes inclusive engagement of these tribes and aids in mapping skill sets, livelihood and inclusive engagement through tourism initiatives is explored.

This paper explores the mechanism of organizational Pao culture in an Oriental cultural context and its impact on CSR implementation and outcomes.

Three short cases are presented to reveal how the traditional Chinese Pao culture influences CSR implementation and outcomes in Chinese firms.

The findings suggest that the traditional Chinese Pao culture is the driver behind the value orientation of the norms of passing on favors and doing good deeds will be rewarded. Knowing this can help leaders in such organizations to incentivize member participation in building organizational Pao culture.

Through the collaborative construction of the core of Pao culture and external evaluation standards of corporate social responsibility, enterprises can thus achieve the dual goals of self-development and social benefits.

Enterprises and managers can be encouraged to draw management wisdom from the essence of cultural norms, so as to achieve the goal of realizing the interests of all CSR participants.

This paper emphasizes the dynamics and outcomes of CSR implementation in the context of the traditional Chinese Pao culture and expands the boundary of CSR research beyond a Western cultural setting.
