Impact of proximity to cell phone tower base stations on residential property prices in the City of Johannesburg, South Africa
Authors: Cheruiyot Koech , Mavundla Nosipho , Siteleki Mncedisi , Lengaram Ezekiel
Published: April 2024

Purpose

With revolutions in the telecommunication sector having led to wide unprecedented consequences in all facets of human life, this paper aims to examine the relationship between cell phone tower base stations (CPTBSs) and residential property prices within the City of Johannesburg (CoJ), South Africa.

Design/methodology/approach

The authors align their work with global literature and assess how the impact of CPTBSs influences residential property values in South Africa. The authors use a semi-log hedonic pricing model to test the hypothesis that proximity of CPTBSs to residential properties does not account for any variation in residential property prices.

Findings

The results show a significant impact that proximity of CPTBS has on residential property sale prices. However, the impact of CTPBSs’ proximity on residential property prices depends on their distance from the residential properties. The closer a residential property is to the CTPBS, the greater the impact that the CTPBS will have on the selling price of the residential property.

Originality/value

With international studies offering mixed findings on the impact of CPTBSs on residential property values, there is limited research on their impact in South Africa. The findings of this study offer crucial insights for the real estate practitioners, property owners, telecommunications companies and the public, providing a nuanced understanding of the relationship between CPTBSs and property values. This research helps property owners understand the effects of CPTBSs on their properties, and it assists property valuers in gauging the impact of CPTBSs on property values.
Putting the cart behind the horse: conceptualising the “emotionality” of mentoring in initial teacher education
Authors: Relihan Mary Clare , O'Donovan Richard
Published: April 2024

Purpose

This conceptual paper explores the complex, and neglected, area of mentor development in initial teacher education (ITE) in Australia. It focuses on the emotionality of mentoring, drawing on concepts of emotional labour and emotional intelligence to develop a framework of effective mentoring that helps explain the essence of a mentor’s role in supporting preservice teachers.

Design/methodology/approach

This conceptual paper draws together mentor-support practice wisdom and research literature from several relevant areas. It draws on constructive developmental theories and complex stage theory to reaffirm the intricate nature of mentor learning and development. This paper critiques the current utilitarian emphasis on mentoring as a way to improve student outcomes without first having clarity on how to improve mentoring itself.

Findings

We introduce the mentoring as emotional labour framework as a way to better understand the nature of mentoring within ITE and as a tool for developing more effective mentor supports. We present “exemplar cases”, which are amalgamations of field observations to illustrate aspects of the framework – however, we do not claim they provide evidence of the utility or accuracy of the framework.

Originality/value

Previous research and policy have tended to gloss over the skills required for effective mentoring, whereas this paper places the emotional labour of mentoring front and centre, explicitly conceptualising and describing the personal and interpersonal skills required in a way that aims to support and empower mentors to recognise existing strengths and areas of potential growth.
How does supply chain transparency influence idiosyncratic risk in newly public firms: the moderating role of firm digitalization
Authors: Zheng Leven J. , Islam Nazrul , Zhang Justin Zuopeng , Wang Huan , Au Kai Ming Alan
Published: April 2024

Purpose

This study seeks to explore the intricate relationship among supply chain transparency, digitalization and idiosyncratic risk, with a specific focus on newly public firms. The objective is to determine whether supply chain transparency effectively mitigates idiosyncratic risk within this context and to understand the potential impact of digitalization on this dynamic interplay.

Design/methodology/approach

The study utilizes data from Initial Public Offerings (IPOs) on China’s Growth Enterprise Board (ChiNext) over the last five years, sourced from the CSMAR database and firms’ annual reports. The research covers the period from 2009 to 2021, observing each firm for five years post-IPO. The final sample comprises 2,645 observations from 529 firms. The analysis employs the Hausman test, considering the panel-data structure of the sample and favoring fixed effects over random effects. Additionally, it applies the high-dimensional fixed effects (HDFE) estimator to address unobserved heterogeneity.

Findings

The analysis initially uncovered an inverted U-shaped relationship between supply chain transparency and idiosyncratic risk, indicating a delicate equilibrium where detrimental effects diminish and beneficial effects accelerate with increased transparency. Moreover, this inverted U-shaped relationship was notably more pronounced in newly public firms with a heightened level of firm digitalization. This observation implies that firm digitalization amplifies the impact of transparency on a firm’s idiosyncratic risk.

Originality/value

This study distinguishes itself by providing distinctive insights into supply chain transparency and idiosyncratic risk. Initially, we introduce and substantiate an inverted U-shaped correlation between supply chain transparency and idiosyncratic risk, challenging the conventional linear perspective. Secondly, we pioneer the connection between supply chain transparency and idiosyncratic risk, especially for newly public firms, thereby enhancing comprehension of financial implications. Lastly, we pinpoint crucial digital conditions that influence the relationship between supply chain transparency and idiosyncratic risk management, offering a nuanced perspective on the role of technology in risk management.
Service quality attributes on customers’ perceived value and behavioral intention of district health centres: a moderating effect of health-care subsidy
Authors: Tavitiyaman Pimtong , Law Tin-Sing Vincent , Fong Yuk-Fai Ben , Ng Tommy K.C.
Published: April 2024

Purpose

This study aims to explore the influence of health-care service quality on customers’ perceived value, satisfaction, effectiveness and behavioural intention concerning district health centres (DHCs) in Hong Kong. This research also intends to assess customers’ perception of the subsidy scheme and its influence on the relationships amongst the aforementioned constructs.

Design/methodology/approach

The convenience and snowball sampling approaches were adopted, and the self-administered questionnaire was sent to 309 customers of DHCs.

Findings

Service quality attributes in terms of staffing and procedures positively increased customers’ perceived value and staffing, procedures and operations. Physical facilities positively promoted customers’ satisfaction, consequently improving DHCs’ effectiveness and behavioural intention. However, core treatments and services of DHCs did not impact customers’ perceived value and satisfaction. Furthermore, customers receiving subsidies exhibited a more positive perception than those without subsidies.

Practical implications

Health-care organisations are advised to strategically allocate resources (staffing, facilities and procedures and operations management) to optimise overall performance outcomes. DHC operators could reinforce the core services of DHCs and health-care voucher subsidies to local citizens so as to enhance the effectiveness of DHCs and behavioural intention of customers.

Originality/value

This study integrates the input–process–output approach in measuring the effectiveness of and customers’ behavioural intention towards newly established DHCs.
COVID-19 crisis – coping up strategies of companies to sustain in markets
Authors: Guttena Revanth Kumar , Atmaja Ferry Tema , Wu Cedric Hsi-Jui
Published: April 2024

Purpose

Pandemics are frequent events, and the impact of each pandemic makes a strong and long-term effect on companies and markets. Given the potential impact of the COVID-19 pandemic, it is important to investigate the crisis from a different perspective to know how companies have sustained growth in markets. The purpose of this paper is to understand how profit-oriented customer-centric companies (small, medium and large) have responded and adapted to COVID-19 crisis, using the complexity theory.

Design/methodology/approach

Drawing upon the complexity theory, a humble attempt is made to develop theoretical propositions by conceptualizing companies as complex adaptive systems. The paper examines companies from three dimensions (i.e. internal mechanism, environment and coevolution).

Findings

Companies self-organize, emerge into new states and become adaptive to the changing environment. Companies create knowledge to understand the dynamic anatomy and design survival and growth strategies during and post COVID-19 era. Complex adaptive systems perspective provides companies with insights to deal with complex issues raised due to COVID-19 pandemic. They can handle the impact of pandemic efficiently with complex adaptive systems by developing and implementing appropriate strategies post-COVID-19.

Originality/value

The study reveals how companies evolve and emerge into as complex adaptive systems to adapt themselves to the highly dynamic environment, which are uncertain, unpredictable, nonlinear and multifaceted, in the context of COVID-19. Implications for theory and practice of viewing companies as complex adaptive systems and coevolving structures in the COVID-19 context are discussed.
The estimate of PTSD symptoms among the residents of violent LOC area of Azad Kashmir
Authors: Batool Hajira
Published: April 2024

Purpose

The purpose of this study aims to investigate the estimated symptoms of posttraumatic stress (PTSD) among the residents of the violent line of control (LoC) of Azad Kashmir.

Design/methodology/approach

This study is a quantitative, exploratory study. The sample comprised 235 males and 225 females, aged 18–35years (N = 460). The traumatic appraisal questionnaire (TAQ) was applied to the determined sample and their responses were statistically analyzed.

Findings

It was identified through quantitative research that people living near the LoC had higher PTSD symptoms as compared to those living farther away. Moreover, females exhibited higher PTSD than males. Religious beliefs were identified as the most common coping mechanism used by residents of LoC.

Practical implications

Awareness sessions and seminars will be conducted with the help of mental health professionals in those areas with high estimated PTSD symptoms. This research will also help mental health professionals in Azad Kashmir to understand PTSD issues of LoC people.

Originality/value

This study focuses on estimating PTSD symptoms among residents living near the LoC in Azad Kashmir, an area characterized by violence and conflict. This research offers practical implications for mental health interventions, such as conducting awareness sessions and seminars with the help of mental health professionals. Furthermore, the study can enhance the understanding of PTSD among LoC residents, aiding mental health professionals in providing more effective support and care.
A product’s connection to self-threat domain determines self-control impairment consequences of within-domain compensatory consumption
Authors: Rustagi Nimish , Shrum L.J.
Published: April 2024

Purpose

Studies have shown that within-domain compensatory consumption can successfully repair the damaged self, but other research indicates that it can undermine self-control because such consumption causes self-threat rumination that impairs self-regulatory resources. This paper aims to identify a boundary condition that reconciles and explains these contradictory findings.

Design/methodology/approach

The authors conducted three experiments to show that within-domain compensatory consumption undermines self-control, but only in some situations. They test a boundary condition (i.e. type of connections between within-domain products and self-threat domain) for the effects of such consumption on self-threat rumination and self-control.

Findings

This paper demonstrates that within-domain (but not across-domain) compensatory consumption induces rumination and reduces subsequent self-control, but only when the product’s connection to the self-threat domain is made explicit through brand names or slogans. When the connection is merely implicit, rumination and self-control deficits are not observed.

Practical implications

Consumers may seek certain products to bolster threatened aspects of their self-concept. Marketing tactics that explicitly highlight connections to such self-aspects can lower a consumer’s self-control resulting in stronger purchase intent, while at the same time hindering the possibility of self-concept repair. Managers need to be wary of ethical concerns.

Originality/value

This research qualifies the existing findings by presenting “type of product connection” as a key determinant of within-domain compensatory consumption’s impact on self-control. Researchers need to be conscious of the type of products (explicitly vs implicitly connected to the self-threat domain) they use in compensatory consumption studies, because this may influence their findings.
Transformative advertising: well-being Instagram messaging
Authors: Dodds Sarah , Palakshappa Nitha , Bulmer Sandy , Harper Sarah
Published: April 2024

Purpose

The purpose of this study is to examine well-being messaging on Instagram to understand what constitutes transformative social media advertising with potential to enhance consumer lives and create change at a community and societal level.

Design/methodology/approach

A novel-phased approach using transformative advertising research and positive psychology is adopted for an in-depth examination of Lululemon, a well-being brand advocate. The study combines secondary case data, analysis of brand messaging on Instagram, interviews with brand followers, and six months of Instagram posts consumer responses.

Findings

Four themes – inspiring personal journeys and potential, encouraging mindfulness and gratitude, supporting connection and community and advancing diversity and equity – are used to develop a typology of well-being advertising message elements on Instagram.

Originality/value

This study contributes to the call for research on transformative advertising by establishing that Instagram is a powerful platform for well-being messages, particularly from brands committed to social issues. Practical implications for brands and avenues for future research are provided.
Intellectual capital information via Twitter: the effect on firm value
Authors: Schiuma Giovanni , Raimo Nicola , Bresciani Stefano , Ricciardelli Alessandra , Vitolla Filippo
Published: April 2024

Purpose

Social media are emerging as the ideal channel for building one-to-many communication and disseminating intellectual capital (IC) information. Their rise is bringing out new research challenges to investigate the implications of their use. However, there needs to be more research contributions relating to the financial benefits of using social media for IC disclosure (ICD). This study aims to bridge this gap by analyzing, under the lens of signaling theory, the effect of ICD through Twitter on firm value.

Design/methodology/approach

This study is based on a content analysis of tweets disseminated by 262 companies aimed at examining the amount of IC information disclosed and on a regression analysis aimed at analyzing the impact of this type of information on firm value.

Findings

Empirical results show that a large ICD via Twitter favors an increase in firm value. They also demonstrate that disclosing information relating to the three IC dimensions positively affects the firm value. These findings suggest that actively and comprehensively communicating IC information via Twitter can help improve the perception and evaluation of the company by investors and other stakeholders.

Research limitations/implications

This study offers empirical evidence about the financial benefits associated with using social media as disclosure tools by companies. It also enriches the literature on the relationship between ICD and firm value and consolidates the goodness of the signaling theory as an ideal theoretical perspective to frame the relationship between IC information and firm value.

Practical implications

This study offers important managerial implications for firms and investors. In light of the significant financial benefits, firms should use social media to disclose IC information and should seek to increase their visibility on such platforms to convey the information to a greater number of users. Investors should also heed social media when gathering IC information, combining the analysis of these platforms with that of traditional corporate documents.

Originality/value

This study enriches the limited literature on ICD via social media and extends knowledge about the relationship between IC information and firm value. In this regard, the originality also lies in the individual analysis of the impact of the three IC dimensions on firm value.
Benefits of a collaborative liquidity management approach: a simulation study for the Indian auto value chain
Authors: Ambadapudi Hariprasad , Matai Rajesh
Published: April 2024

Purpose

Liquidity is a primary concern for businesses. The purpose of this study is to understand the impact of the collaborative liquidity management within the supply chain. Larger firms prescribe favorable trade terms in the transactions and do not engage in value chain vision sharing with their smaller counterparts. Smaller firms encounter challenges with liquidity and often face the risk of bankruptcy. Such practice can threaten the entire supply chain. Instead, collaborative liquidity management can offer a win–win scenario to both parties. In that case, what are the benefits of implementing a collaborative liquidity management approach across the value chain, and what is the reward?

Design/methodology/approach

The authors selected key liquidity metrics that matter most to the organizations from a cohort of 307 firms from the Indian automobile industry for 10 years (2012–2021). The authors classified the businesses into five distinct revenue-based categories. They emphasized the importance of expanded supply chain finance adoption and demonstrated how collaborative liquidity management strategies boosted return on assets.

Findings

The research confirms the tangible benefits of greater adoption of supply chain finance in realizing supply chain members’ shared vision. The authors challenged the age-old practice of power-based relationships in the supply chain. They recommended a win–win scenario through practical cooperation and increased adoption of SCF by value chain members.

Originality/value

Existing research predominantly focuses on dyadic relationships and is restricted to Europe and China. According to the authors, no comprehensive investigation has been conducted in India. This application of simulation techniques to improve the liquidity performance of companies in developing economies is innovative.
Is the exchange rate exposure puzzle really a puzzle? International evidence
Authors: Tai Chu-Sheng
Published: April 2024

Purpose

Given the difficulties in finding significant exchange rate exposure in the extant literature, this paper attempts to resolve the so-called “exposure puzzle” by investigating whether currency movements have any significant impact on international industry returns.

Design/methodology/approach

This paper utilizes the multivariate Generalized AutoRegressive Conditional Heteroskedasticity (MGARCH) methodology to estimate both symmetric and asymmetric exchange rate exposures for each industry common across 12 countries simultaneously.

Findings

The empirical results show that exchange rate exposure is not only statistically significant but also economically important based on the estimation of an asymmetric three-factor exposure model using MGARCH methodology. This is an extremely important finding as it suggests that the “exposure puzzle” may not be a puzzle at all once a better methodology is utilized in the estimation.

Research limitations/implications

Because this study tries to resolve the exchange rate exposure puzzle by focusing on whether exchange rate movements affect ex-post returns as opposed to ex ante expected returns and given the significant exposures with respect to different risk factors found in the study, it is interesting to see if any of these risk factors commands a risk premium. In other words, a natural extension of this study is to test whether any of these risk factors is priced in international industry returns.

Practical implications

The findings of the study have interesting implications for international investors who would like to diversify their portfolios across different industries and are concerned about whether the unexpected movements in the bilateral exchange rates will affect their portfolio returns in addition to its interest rate and world market risk exposures.

Originality/value

The study utilizes the MGARCH methodology, which has not been fully exploited in the exchange rate exposure literature.
Rational versus intuitive cognition and influence of dynamic managerial capabilities on SMEs’ perceived international performance: evidence from emerging economy
Authors: Karaca Volkan , Bağış Mehmet
Published: April 2024

Purpose

This study aims to investigate the relationships between managers’ cognitive styles, dynamic managerial capabilities and firms’ perceived international performance. The study is based on cognitive-experiential self-theory, dynamic managerial capabilities and international entrepreneurship.

Design/methodology/approach

Data were collected from 283 managers of small medium enterprises (SMEs) in Türkiye, an emerging economy. The research was conducted using quantitative methods, and Smart partial least squares (PLS) 4 software was used for data analysis. The data were examined through structural equation modelling and mediation analyses.

Findings

Findings indicate that rational cognitive styles positively influence managerial human capital, managerial social capital, managerial cognition and perceived international performance. However, the effect of intuitive cognitive styles was confirmed only on managerial cognition. Additionally, it was found that managerial cognition positively affects perceived international performance, whereas managerial social capital has a negative impact. However, the effects of managerial human capital could not be confirmed. Moreover, a full mediation relationship of managerial cognition between intuitive cognitive styles and perceived international performance was identified.

Originality/value

This research carves out a unique niche by synergizing cognitive-experiential self-theory with dynamic managerial capabilities to investigate their conjoined effect on firms’ international performance, an area previously underexplored. Unveiling insights from burgeoning economies like Türkiye enriches the existing body of knowledge, offering substantial contributions to the field of international business.
The role of edible mushrooms in the Brazilian diet: a comprehensive analysis
Authors: Carvalho Ana Júlia Souto , Zárate-Salazar Jhonatan Rafael , Jacob Michelle Cristine Medeiros , Araújo Patrícia Lima , Gomes Sávio Marcelino , Pereira Fillipe De Oliveira
Published: April 2024

Purpose

This study aims to examine the role of edible mushrooms in the Brazilian diet, considering their strategic significance in meeting nutritional goals within sustainable development. Despite their potential in the nutrition of the Brazilian population, significant knowledge gaps still exist. To address this, the authors formulated this study into five main sections: the consumption of edible mushrooms in Brazil, the factors influencing the consumption, the occurrence of edible mushrooms in Brazil, the nutritional contribution of mushrooms consumed in Brazil and sustainable mushroom production in Brazil.

Design/methodology/approach

The authors compiled current literature to develop this viewpoint paper using systematic review, systematic search and narrative review search methods.

Findings

Mushrooms are sporadically consumed in Brazil, primarily by the urban population, with challenges in estimating the most used species. Social, economic and cultural factors, health considerations and reduced meat consumption influence mushroom consumption behavior. While Pleurotus ostreatus, Lentinula edodes and Agaricus bisporus are primary species, ethnomycological studies highlight a more diverse consumption among traditional indigenous communities. Brazil hosts approximately 133 wild mushroom species safe for human consumption. Some can be sustainably cultivated using substrates derived from agricultural and urban waste, offering high-protein, high-fiber, low-fat foods with bioactive compounds holding antioxidant and prebiotic potential.

Originality/value

To the best of the authors’ knowledge, no previous study has investigated how edible mushrooms contribute to the food and nutrition of the Brazilian population. This study emphasizes the crucial role of edible mushrooms in preserving Brazil’s cultural heritage, contributing to food and nutritional security and enhancing the overall diet quality.
Service quality assessment in a Greek teacher training program: a cultural perspective
Authors: Athanasiadis Anastasios , Papadopoulou Vassiliki , Tsakiridou Helen , Iordanidis George
Published: April 2024

Purpose

This paper aims to investigate the relationship between prospective teachers’ cultural profiles and service quality expectations in a pedagogical training program in Greece.

Design/methodology/approach

Using the EppekQual scale and an alternative Hofstede’s cultural scale, 113 prospective teachers in a Greek training program were surveyed. The study uses descriptive statistics, correlation analysis and multiple regression, validating measurements through confirmatory factor analysis.

Findings

Prospective teachers exhibit a low-power orientation and a preference for feminine values. Rejecting hierarchy correlates with quality expectations, especially in the curriculum dimension, emphasizing student-centric education. A positive correlation with acceptance/avoidance of uncertainty is observed, notably in learning outcomes and administrative services. The cultural aversion to ambiguity shapes individuals’ prioritization of all quality dimensions. A realistic long-term perspective correlates positively with expectations in learning outcomes, aligning with Greek culture’s emphasis on security. Contrary to expectations, a predilection for feminine values positively impacts service quality expectations, particularly in curriculum, learning outcomes and academic staff dimensions. The hypothesis related to individualism/collectivism is not substantiated, indicating a negative association with the curriculum dimension.

Practical implications

Tailoring program designs to embrace student-centric and collaborative learning environments is recommended. Acknowledging cultural aversions to uncertainty, program flexibility and clarity are essential. Integrating career planning and mentorship aligns with realistic long-term perspectives. The need for a balanced approach to personal and intellectual development is also suggested.

Originality/value

This study uncovers specific cultural dimensions that shape quality expectations within a Greek teacher training context.
Cutaneous manifestations of adult‐onset Still's disease: A comparative study between young‐onset and elderly‐onset groups
Authors: Sato Mayu , Yamamoto Toshiyuki
Published: April 2024

We investigated the detailed characteristics and proportions of typical and atypical rashes in 28 patients with adult‐onset Still's disease (AOSD) by retrospectively examining the clinical symptoms and pathological features. The patients consisted of six males and 22 females aged between 23 and 85 years. The skin rashes observed in the study population were as follows: (i) typical rash in six cases, (ii) atypical rash in 19, and (iii) both typical and atypical rash in three cases (in all three cases, typical rash preceded atypical rash). Furthermore, we classified atypical rashes into persistent pruritic papules and plaques (PPPP) and others. In 22 cases of atypical rashes, 10 cases had PPPP. In a comparison between young‐onset (<65 years) (n = 16) and elderly‐onset (≥65 years) (n = 12) AOSD cases, typical rashes were observed more frequently in the young‐onset cases. Regarding atypical rashes, PPPP was significantly more common in the elderly‐onset cases.
Looking at the bid picture: A framework for identifying reverse auctions in ecological systems
Authors: Fowler Katherine J. , Potratz Emily J. , Malone Margaret , Halloway Abdel , Peplinski Joy , Brown Joel S.
Published: April 2024

Biological market theory can be used to explain intraspecific cooperation, interspecific mutualism, and sexual selection through models of game theory. These models describe the interactions between organisms as two classes of traders (buyers/sellers) exchanging commodities in the form of goods (e.g. food, shelter, matings) and services (e.g. warning calls, protection). Here, we expand biological market theory to include auction theory where bidding serves to match buyers and sellers.

In a reverse auction, the seller increases the value of the item or decreases the cost until a buyer steps forward. We provide several examples of ecological systems that may have reverse auctions as underlying mechanisms to form mutualistic relationships.

We focus on the yellow baboon (Papio cynocephalus) mating system as a case study to propose how the mechanisms of a reverse auction, which have the unintended but emergent consequence of producing a mutually beneficial outcome that improves collective reproductive benefits of the troop in this multi‐female multi‐male polygynandrous social system. For the yellow baboon, we posit that the “seller” is the reproductively cycling female, and the “buyer” is a male looking to mate with a cycling female. To the male, the “item for the sale” is the opportunity to sire an offspring, the price is providing safety and foraging time (via consortship) to the female. The “increasing value of the item for sale” is the chance of conception, which increases with each cycle since a female has resumed cycling post‐partum. The female's sexual swelling is an honest indicator of that cycle's probability of conception, and since resident males can track a female's cycle since resumption, there is transparency. The males presumably know the chance of conception when choosing to bid by offering consortship.

Across nature, this reverse auction game likely exists in other inter‐ and intraspecific social relationships. Considering an ecological system as a reverse auction broadens our view of social evolution and adaptations through the lens of human economic structures.
Design principles for multi‐species productive grasslands: Quantifying effects of diversity beyond richness
Authors: Finn John A. , Suter Matthias , Vishwakarma Rishabh , Oram Natalie J. , Lüscher Andreas , Brophy Caroline
Published: April 2024

Productive grasslands in temperate regions have relied strongly on low plant diversity with high management intensity and fertiliser inputs. Increasing plant diversity can provide high yields of digestible forage for livestock production with lower environmental impacts, and thus represents a diversity‐dependent nature‐based solution that can deliver multiple ecosystem functions.

Sharing lessons from the design of managed, productive grassland communities, we address the following questions: how can we identify combinations of plant species that best deliver a selected function or multiple functions? and; when is community composition more important than species richness?

We describe approaches that separate plant diversity into its underlying components: species richness, composition and relative abundance. Disentangling these three components facilitates a more nuanced understanding of how diversity can contribute to the design of diversity‐dependent nature‐based solutions.
Overview of the distinctive characteristics of strawberry, raspberry, and blueberry in berries, berry wines, and berry spirits
Authors: Bezerra Mário , Ribeiro Miguel , Cosme Fernanda , Nunes Fernando M.
Published: April 2024

Red berries have gained popularity as functional and nutritious food due to their health benefits, leading to increased consumer demand and higher production, totaling over 11,000 ktons for strawberries, raspberries, and blueberries combined in 2021. Nutritionally, strawberries, raspberries, and blueberries present high levels of vitamin C (9.7–58.8 mg/100 g dry weight [dw]), folates (6–24 µg/100 g dw), and minerals (96–228 mg/100 g dw). Due to their perishable nature, producers have utilized alcoholic fermentation to extend their shelf life, not only increasing the lifespan of red berries but also attracting consumers through the production of novel beverages. Strawberry, blueberry, and raspberry wines possess low alcohol (5.5–11.1% v/v), high acidity (3.2–17.6 g/L), and interesting bioactive molecules such as phenolic compounds, carotenoids, polysaccharides, and melatonin. Distillation holds tremendous potential for reducing food waste by creating red berry spirits of exceptional quality. Although research on red berry spirits is still in the early stages, future studies should focus on their production and characterization. By incorporating these factors, the production chain would become more sustainable, profitable, and efficient by reducing food waste, capitalizing on consumer acceptance, and leveraging the natural health‐promoting characteristics of these products. Therefore, this review aims to provide a comprehensive overview of the characteristics of strawberry, blueberry, and red raspberry in berries, wines, and spirits, with a focus on their chemical composition and production methods.
COVID‐19’s effects on sense of place and pro‐environmental behaviour
Authors: Li Guangzhen , Evensen Darrick , Stedman Rich
Published: April 2024

COVID‐19 substantially disrupted daily life globally. Human geography and environmental psychology scholars have argued that dramatic shifts in how people used urban environments during the pandemic could have important implications for those studying human–environment relationships and for planners designing urban spaces. Nevertheless, empirical data that examine shifts in human–environment relationships in urban areas during the pandemic are still limited. We explored how COVID‐19 influenced sense of place and investigated how sense of place and changes to daily life because of the pandemic affected environmentally friendly behaviours. A case study involved working with 10 interview participants and 302 survey respondents in Wuhan, China—the city where the pandemic started, and which experienced very strict lockdowns. Data collection occurred in June 2021. The results reveal three main findings. First, stronger emotions directed towards the pandemic and heightened pandemic responses positively affected sense of place, with response behaviours including taking disease prevention measures, spending more time with families/friends, and helping others during the crisis. Second, sense of place and behavioural response to the pandemic were both associated with environmentally friendly behaviours, but not with environmentally friendly attitudes. Third, the nation and city, rather than the community level, are the geographic scales most consonant with respondent notions of place; sense of place grew most at these scales during the pandemic. We conclude that contrary to some speculation, sense of place was enhanced during the pandemic, at least in Wuhan. The pandemic also provided an opportunity for behaviour transitions, but not necessarily via changes in sense of place.
Unravelling the role of the group 6 soluble di‐iron monooxygenase (SDIMO) SmoABCD in alkane metabolism and chlorinated alkane degradation
Authors: Ferrari Eleonora , Di Benedetto Giulio , Firrincieli Andrea , Presentato Alessandro , Frascari Dario , Cappelletti Martina
Published: April 2024

Soluble di‐iron monooxygenases (SDIMOs) are multi‐component enzymes catalysing the oxidation of various substrates. These enzymes are characterized by high sequence and functional diversity that is still not well understood despite their key role in biotechnological processes including contaminant biodegradation. In this study, we analysed a mutant of Rhodoccocus aetherivorans BCP1 (BCP1‐2.10) characterized by a transposon insertion in the gene smoA encoding the alpha subunit of the plasmid‐located SDIMO SmoABCD. The mutant BCP1‐2.10 showed a reduced capacity to grow on propane, lost the ability to grow on butane, pentane and n‐hexane and was heavily impaired in the capacity to degrade chloroform and trichloroethane. The expression of the additional SDIMO prmABCD in BCP1‐2.10 probably allowed the mutant to partially grow on propane and to degrade it, to some extent, together with the other short‐chain n‐alkanes. The complementation of the mutant, conducted by introducing smoABCD in the genome as a single copy under a constitutive promoter or within a plasmid under a thiostreptone‐inducible promoter, allowed the recovery of the alkanotrophic phenotype as well as the capacity to degrade chlorinated n‐alkanes. The heterologous expression of smoABCD allowed a non‐alkanotrophic Rhodococcus strain to grow on pentane and n‐hexane when the gene cluster was introduced together with the downstream genes encoding alcohol and aldehyde dehydrogenases and a GroEL chaperon. BCP1 smoA gene was shown to belong to the group 6 SDIMOs, which is a rare group of monooxygenases mostly present in Mycobacterium genus and in a few Rhodococcus strains. SmoABCD originally evolved in Mycobacterium and was then acquired by Rhodococcus through horizontal gene transfer events. This work extends the knowledge of the biotechnologically relevant SDIMOs by providing functional and evolutionary insights into a group 6 SDIMO in Rhodococcus and demonstrating its key role in the metabolism of short‐chain alkanes and degradation of chlorinated n‐alkanes.
Prevalence of left atrial appendage thrombus and spontaneous echo contrast on transesophageal echocardiography in patients scheduled for pulmonary vein isolation
Authors: Mannewald Christine , Roijer Anders , Platonov Pyotr G. , Holmqvist Fredrik
Published: April 2024

Background

To avoid causing a thromboembolic event in patients undergoing catheter ablation for atrial fibrillation (AF), patients are treated with oral anticoagulants (OAC) prior to the procedure. Despite being on anticoagulants, some patients develop a left atrial appendage thrombus (LAAT). To exclude the presence of LAAT, transesophageal ultrasound (TEE) is performed in all patients prior to the procedure. We hypothesized continuous treatment with anticoagulants would result in a low prevalence of LAAT, in patients with low CHA2DS2‐VASc score.

Method

Medical records of consecutive patients planned to undergo AF ablation at Lund University Hospital during the years 2018–2020 were reviewed retrospectively. Examination protocols from transesophageal and transthoracic echocardiography were examined for LAAT and spontaneous echo contrast (SEC). Patients with LAAT and SEC were compared to patients without using Mann–Whitney U‐test and Pearson Chi‐squared analysis to test for correlation.

Results

Of 553 patients, three patients (0.54%) had LAAT, and 18 (3.25%) had spontaneous contrast (SEC). Patients with LAAT or SEC had a higher CHA2DS2‐VASc score, more often presented in AF at TEE and less often had a normal sized left atrium.

Conclusion

There is a low prevalence of LAAT and SEC in patients with AF scheduled for pulmonary vein isolation. Patients with SEC or LAAT tend to have paroxysmal AF less often and more often presented in AF at admission. No patients with CHA2DS2‐VASc 0, paroxysmal AF, normal sized left atrium and sinus rhythm at TEE were found to have LAAT or SEC.

Aim

With the rise of structured, remote follow‐up of colorectal cancers, there is the potential risk of underdiagnosing and undermanaging low anterior resection syndrome (LARS). This cohort study aims to determine the rate of LARS and its patterns of care, with the aim of generating a risk‐stratified management algorithm that can be employed for nurse‐led follow‐up.

Method

Patients who underwent elective anterior resection for the management of colorectal cancer between 1 January 2017 and 31 December 2021 were sent quality‐of‐life questionnaires (EORTC‐QLQ‐CR29 and LARS score) and surveyed for LARS symptoms and management utilized.

Results

Out of 70 patients who completed questionnaires, 71.4% had LARS and 42.9% had major LARS. The international Delphi consensus definition identified more patients (n = 50) with LARS than the LARS score (n = 41). Tumours located <8 cm from the anal verge, ULAR, and temporary stoma were predictive of major LARS on univariate analysis. However, only temporary stoma was predictive for LARS (OR 7.89 (1.15–53.95), P = 0.035) and majors LARS (8.14 (1.79–37.01), P = 0.007) on multivariate analysis. Forty‐four percent of patients with LARS did not have input from any health professional for this condition. Consultation with specialist allied health and/or colorectal surgeons ranged from 4% to 22%.

Conclusions

Our study highlights that with the current remote follow‐up system focused on cancer outcomes a significant proportion of patients with LARS are overlooked, resulting in the underutilization of relevant health professionals and management options. We propose a nurse‐led management algorithm to address this issue while still minimizing surgical outpatient load.

This case study examines the use of X‐ray fluorescence (XRF) as an effective method for defining distinct chemical compositions of local basalt stone from different sources in the Roman period, even when their quarries have not been identified. It also deals with the archaeological question if public and monumental structures from a village and urban site shared the same stone sources and stonemason's workshops. Ninety‐six samples from the Hippos Territorium, mainly from the polis of Hippos and the village of Majduliyya, were analyzed. XRF was found to be an effective method for defining distinct chemical compositions of local basalt materials from different sources. The distinct composition of the basalt stones between the two sites provided valuable insights into socio‐economic relationships, shedding light on the nature of city–village dynamics in the region. Additionally, it aids in discerning whether diverse basalt sources were utilized in both private and public constructions, as well as installations within a single site. Methodological questions and the application of this method in the archaeological research of basalt‐based architecture are also addressed.

Polycystic ovary syndrome or PCOS is an endocrine disorder in women of reproductive age. It is a diversified multi factorial disorder and diagnosis is very complicated because of its overlapping symptoms some of which are irregular menstrual cycle, acne in face, excess level of androgen (AE), insulin resistance, obesity, cardiovascular disease, mood disorder and type 2 diabetes (T2DM). PCOS may be caused by hormonal imbalance, genetic and epigenetic vulnerability, hypothalamic and ovarian troubles. PCOS is essentially hyperandrogenimia with oligo‐anovulation. This review explains the abnormal regulation of autophagy related genes and proteins in different cells at various stages which leads to the genesis of PCOS. During nutrient starvation cells face stress condition, which it tries to overcome by activating its macroautophagy mechanism and by degrading the cytoplasmic material. This provides energy to the cell facilitating its survival. Downregulation of autophagy related genes in endometria has been observed in PCOS women. PCOS can be managed by maintaining proper lifestyle and medical treatment. Healthy meals and regular exercise can prevent the excessive weight and also reduce the PCOS complications. Medicines such as metformin, clomiphene, and the oral contraceptive pill can also balance the hormonal level. The imbalance in regulation of autophagy genes has been discussed with correlation to PCOS. The different management strategies for PCOS have also been summarized.
AdipoRon promotes amyloid‐β clearance through enhancing autophagy via nuclear GAPDH‐induced sirtuin 1 activation in Alzheimer's disease

Background and Purpose

Amyloid‐β (Aβ) peptide is one of the more important pathological markers in Alzheimer's disease (AD). The development of AD impairs autophagy, which results in an imbalanced clearance of Aβ. Our previous research demonstrated that AdipoRon, an agonist of adiponectin receptors, decreased the deposition of Aβ and enhanced cognitive function in AD. However, the exact mechanisms by which AdipoRon affects Aβ clearance remain unclear.

Experimental Approach

We studied how AdipoRon affects autophagy in HT22 cells and APP/PS1 transgenic mice. We also investigated the signalling pathway involved and used pharmacological inhibitors to examine the role of autophagy in this process.

Key Results

AdipoRon promotes Aβ clearance by activating neuronal autophagy in the APP/PS1 transgenic mice. Interestingly, we found that AdipoRon induces the nuclear translocation of GAPDH, where it interacts with the SIRT1/DBC1 complex. This interaction then leads to the release of DBC1 and the activation of SIRT1, which in turn activates autophagy. Importantly, we found that inhibiting either GAPDH or SIRT1 to suppress the activity of SIRT1 counteracts the elevated autophagy and decreased Aβ deposition caused by AdipoRon. This suggests that SIRT1 plays a critical role in the effect of AdipoRon on autophagic induction in AD.

Conclusion and Implications

AdipoRon promotes the clearance of Aβ by enhancing autophagy through the AdipoR1/AMPK‐dependent nuclear translocation of GAPDH and subsequent activation of SIRT1. This novel molecular pathway sheds light on the modulation of autophagy in AD and may lead to the development of new therapeutic strategies targeting this pathway.
