Novice principal mentoring and professional development
Authors: Pariente Nirit , Tubin Dorit
Published: July 2021

Purpose

This article explores the contribution of mentoring to the professional development of novice principals. Based on Abbott’s (1988) framework, the authors suggest that effective mentoring depends on the extent it develops professional core knowledge, which includes the skills of diagnosis, intervention and inference that are heavily based on academic knowledge, practical experience, self-awareness and reflective ability.

Design/methodology/approach

An exploratory qualitative methodology was applied to discover principals’ perceptions of their mentoring. The authors interviewed 15 novice principals about their mentoring events and conducted a category-based analysis to find out how these events reflect contributions to their diagnosis, intervention and inference skills.

Findings

The study found that most of the mentoring events provided support for the intervention skill, while ignoring the skills of diagnosis and inference. We suggest that to develop novice principals professionally, mentors should place similar emphasis on all three skills.

Research limitations/implications

The small research population and its possible bias toward positive mentoring experience may present only part of the picture. Still, the data provided important insights into how mentoring supports (or not) professional skills development, even in the best cases. Using professional skills in a large sample survey of effective and less effective mentoring relationships would help to validate this framework.

Practical implications

First, the findings serve as a guideline for mentor training programs to help develop mentors’ ability to support all three professional skills. Second, the findings may help novice principals to evaluate their mentoring relationships and their contribution to developing professional core knowledge skills.

Originality/value

The professional skills framework adds to the principal mentoring literature by emphasizing the importance of diagnosis, intervention and inference skills, in addition to certain content and specific conditions.
Gender disparity in leadership boosts affective commitment and tacit knowledge sharing about libraries
Authors: Sharif Shahbaz , Lodhi Rab Nawaz , Iqbal Khurshed , Saddique Fahad
Published: July 2021

Purpose

This study aims to use an authentic leadership style to explore that whether male or female leadership of private academic institutions highly influences affective organizational commitment and tacit knowledge sharing among the library teachers. Additionally, this study encompasses the trust of library teachers and justifies whether the trust under male or female leadership highly moderates the effect on tacit knowledge sharing.

Design/methodology/approach

By using structural equation modeling, this study tests two leadership models (e.g. male and female leadership models). Using a convenient sampling approach, the researcher collects data from library teachers of private academic institutions in district Sheikhupura, Pakistan through face-to-face interaction. The study administered 650 survey questionnaires among the library teachers; however, 403 questionnaires were answered validly and reliably. The response rate was 62%.

Findings

The study found the direct and indirect effect of authentic leadership on affective organizational commitment and tacit knowledge sharing however, male authentic leadership influence on affective organizational commitment and tacit knowledge sharing was quite higher than female authentic leadership. Resultantly, the library teachers were more committed to sharing tacit knowledge under male leadership than female. Nevertheless, the moderating role of trust was found in female leadership but not in male leadership. Simply, the library teachers under male leadership were hesitant to trust others, so the chain of sharing hidden ideas and image of libraries was not found in male leadership.

Practical implications

Private academic institutions need authentic leaders to shape the knowledge economy of libraries and the structure of the academic institutions. For this reason, this study provides practical implications for managers that male leadership should be hired in academic institutions because it has a higher influence on librarians’ commitment and tacit knowledge sharing among peers as compare to female leadership.

Originality/value

To the best of the authors’ knowledge, this was the first study that differentiates the capabilities and skills of male and female authentic leadership in private academic institutions. Further, it suggests hiring male leaders in these institutions.

Factors influencing health anxiety: the stimulus–organism–response model perspective
Authors: Yang Xuejie , Gu Dongxiao , Wu Jiao , Liang Changyong , Ma Yiming , Li Jingjing
Published: July 2021

Purpose

With the popularity of the internet, access to health-related information has become more convenient. However, the easy acquisition of e-health information could lead to unfavorable consequences, such as health anxiety. The purpose of this paper is to explore a set of important influencing factors that lead to health anxiety.

Design/methodology/approach

Based on the stimulus–organism–response (S-O-R) framework, we propose a theoretical model of health anxiety, with metacognitive beliefs and catastrophic misinterpretation as the mediators between stimulus factors and health anxiety. Using 218 self-reported data points, the authors empirically examine the research model and hypotheses.

Findings

The study results show that anxiety sensitivity positively affects metacognitive beliefs. The severity of physical symptoms has a significant positive impact on catastrophic misinterpretation. Metacognitive beliefs and catastrophic misinterpretation have significant positive impacts on health anxiety.

Originality/value

Based on the S-O-R model, this paper develops a comprehensive model to explain health anxiety and verifies the model using firsthand data.
From CAD design to robot models and simulation tools. Test-case example using the Kassow 810 collaborative robot
Authors: Pires J. Norberto , Zhu Carlos Ye
Published: July 2021

Purpose

This paper aims to introduce, in a tutorial form, a collection of procedures, tools and applications that can be used to explore robotics fundamentals and automatically generate kinematic and dynamic models from computer-aided design (CAD) packages, to create representations of the robot manipulator understudy so that a user can generate trajectories and to simulate and visualize the robot motion using several programming, simulation and developing tools. In this paper, the authors are particularly interested in advanced three-dimensional design packages such as Inventor and SolidWorks, interactive mathematical and simulation environments such as Matlab, Simulink, Simscape Multibody and Robot Operating System, and several application development languages such as C# and Python. A few of them will be used throughout the paper in a collection of examples that use the new Kassow 810 collaborative robot as a test-case demonstration. In the process, the authors expect readers to fully understand how to use all these tools to other machines and to their own designs.

Design/methodology/approach

Consequently, the paper follows a step-by-step practical procedure, fully tested and explained using the already mentioned state-of-the-art collaborative robot, guiding the reader from the design, modeling, simulation and application development phases, which may be applied to other machines and robotic designs.

Findings

The results clearly show that the procedure of starting from a CAD design to generate the kinematic and dynamic models of a robot manipulator create representations of the robot, generate trajectories and simulate/visualize the robot motion is feasible and accessible to a general user (using standard tools).

Research limitations/implications

Although the paper uses a few particular software packages, the concepts and kept general, which means that they can be used with other equivalent tools. With that objective in mind, the paper introduces the basic robotics concepts involved, further increasing in this way its tutorial structure.

Originality/value

Consequently, the presented procedure has the inherent value of introducing robotics fundamentals in a practical way, but also of demonstrating how readers can build and explore advanced robotic designs using common design, simulation and programming tools.
A parallel-series hybridization of seasonal intelligent based statistical model for demand forecasting
Authors: Bahrami Maryam , Khashei Mehdi , Amindoust Atefeh
Published: July 2021

Purpose

The purpose of this paper, because of the complexity of demand time series and the need to construct a more accurate hybrid model that can model all relationships in data, is to propose a parallel-series hybridization of seasonal neural networks and statistical models for demand time series forecasting.

Design/methodology/approach

The main idea of proposed model is centered around combining parallel and series hybrid methodologies to use the benefit of unique advantages of both hybrid strategies as well as intelligent and classic seasonal time series models simultaneously for achieving results that are more accurate for the first time. In the proposed model, in contrast of traditional parallel and series hybrid strategies, it can be generally shown that the performance of the proposed model will not be worse than components.

Findings

Empirical results of forecasting two well-known seasonal time series data sets, including the total production value of the Taiwan machinery industry and the sales volume of soft drinks, indicate that the proposed model can effectively improve the forecasting accuracy achieved by either of their components used in isolation. In addition, the proposed model can achieve more accurate results than parallel and series hybrid model with same components. Therefore, the proposed model can be used as an appropriate alternative model for seasonal time series forecasting, especially when higher forecasting accuracy is needed.

Originality/value

To the best of the authors’ knowledge, the proposed model, for first time and in contrast of traditional parallel and series hybrid strategies, is developed.

Authors: Karani Anushree , Trivedi Payal , Thanki Heena
Published: July 2021

Purpose

The purpose of the current research is to examine the impact of psychological contract fulfillment on work outcomes i.e. organizational commitment and job satisfaction during the COVID-19 pandemic. It also aims to check the mediating role of co-worker support and work engagement on organizational outcomes.

Design/methodology/approach

The current study has adopted a quantitative approach and a cross-sectional research design has been used with a snowball sampling technique. Data were collected via a structured questionnaire through Google Docs from 926 respondents working at different capacities in the service sector. The study includes those respondents who are working from home during the COVID-19 pandemic situation. The hypotheses were tested using structural equation modeling (SEM).

Findings

Results indicated that psychological contract fulfillment was positively impacting work outcomes i.e. organizational commitment and job satisfaction. Co-worker support and work engagement positively mediated the relationship between psychological contract fulfillment and work outcomes during the COVID-19 pandemic situation. Multi-group analysis proved that there was a difference in opinion regarding the impact of psychological contract fulfillment on organizational commitment and job satisfaction amongst males and females.

Originality/value

The novel contribution of the study is integrating social exchange theory, organization support theory and social information processing theory during the pandemic situation. The results highlighted meticulous empirical evidence, which answers the question as to how the met expectations cause an advantageous effect on the employees as well as the organizations in this COVID-19 pandemic situation.
Why should you respond to customer complaints on a personal level? The silent observer's perspective
Authors: López-López Inés , Palazón Mariola , Sánchez-Martínez José Antonio
Published: July 2021

Purpose

This paper analyzes the effect of company response style and complaint source on silent observers' reactions to a service failure episode vented on Twitter.

Design/methodology/approach

In a 2 × 2 experimental design, company response style (personalized vs automatic) and complaint source (ordinary Twitter user vs influencer) were manipulated to test the hypotheses.

Findings

Complaint source moderates the effect of company response style on brand image, purchase intention and electronic word-of-mouth (eWOM). Thus, the authors found that a personalized response to a complaint, compared to an automatic response, leads to a more favorable brand image as well as purchase intention and eWOM intention when the complainant is an ordinary Twitter user. However, the automatic response, compared to the personalized one, is better perceived when the complainant is an influencer. The authors also found that service failure response attribution and the emotions elicited during the firm–complainant interaction mediate the previous effects.

Research limitations/implications

This paper deals with the company's initial reaction after a complaint is posted on Twitter; however, the complaint-handling process is longer, and both the customer and silent observers await a resolution. Future research could tackle subsequent stages of the process and different recovery strategies.

Practical implications

The study offers meaningful insights regarding complaint handling on Twitter and how the effectiveness of the company response style depends on the complaint source. Marketers should offer adapted personalized responses to prompt positive behavioral intentions for ordinary Twitter users, who represent prospective consumers. However, a personalized response given to an influencer may be perceived more negatively, as silent observers may interpret that the company offers such a response just because the complaint comes from a well-known person who can reach many users and not because of an honest interest in serving consumers.

Originality/value

This research focuses on the underresearched area of the impact of online complaints on silent observers, a large group of prospective consumers quietly exposed to complaints aired on Twitter. The underlying mechanisms are also identified.
Firm-level attributes of inflationary expectations of entrepreneurs: evidence from the Pakistan economy
Authors: Qayyum Waqqas , Malik Wasim Shahid
Published: July 2021

Purpose

The purpose of this research is to bring upfront some unconventional attributes of inflationary expectations of entrepreneurs. Firm-level attributes are instrumental in shaping the behavior of entrepreneurs, which affect the way in which they form their expectations regarding some key economic variables, like inflation. Inflationary expectations are considered important based on their significant role in affecting decisions taken by individuals, firms and policy makers. Among all economic segments, it is vital to account the inflationary expectations of entrepreneurs representing firms because their decisions critically define the future path of actual inflation and inflation inertia. This basic purpose of this paper is to offer a deterministic framework for these expectations contingent upon the firm-level attributes.

Design/methodology/approach

This paper provides survey-based evidence on inflationary expectations of entrepreneurs of the selected manufacturing, trading and service sector firms from Pakistan. Additionally, the study has focused on identifying some firm-level attributes, including market experience of the firm, scale of production, myopia in price setting behavior, forward and backward-looking behavior, rationality of the entrepreneur and the entrepreneur's relative firm-level experience as determinants of these expectations. The specified variables are constructed based on responses captured through a structured questionnaire.

Findings

Within an ordinal logistic framework, the study finds that the said attributes including market experience of the firm, scale of production, myopic tendency of entrepreneur in price setting, forward and backward-looking behavior, rationality of the entrepreneur and the entrepreneur's relative firm-level experience play a pivotal role in explaining differentials and heterogeneity in reported level of inflationary expectations.

Originality/value

The study brings upfront some unconventional attributes of inflationary expectations at entrepreneurial level. The work is unique in a sense that it provokes researchers to account behavioral and individualistic attributes within a deterministic framework for inflationary expectations.
What drives e-hailing apps adoption? An analysis of behavioral factors through fuzzy AHP
Authors: Arora Manoj , Singh Harpreet , Gupta Sanjay
Published: July 2021

Purpose

In the era of digitalization and technology, tremendous changes have taken place in the taxi industry worldwide. The traditional taxi service has transformed into the latest innovative technology-based e-hailing service. There are innumerable factors that drive the user adoption of e-hailing apps. This study aims to primarily concentrate on identifying, analyzing and ranking these factors which have an impact on the user intention toward using e-hailing apps.

Design/methodology/approach

The e-hailing app users in the state of Punjab and Chandigarh are the target population for the study. A fuzzy analytical hierarchy process technique has been applied to analyze and codify the determinants that influence the user intention of adopting e-hailing apps. The primary factors that have been considered for the study are social influence, perceived usefulness, facilitating conditions, perceived ease of use, self-efficacy, perceived risk, compatibility and trust.

Findings

The study revealed that “Perceived Usefulness” is the factor that influences user intention to use e-hailing apps the most, while “Perceived Risk” the least. The sub-criteria codified in the top priority was as follows: “Overall, I find the e-hailing app useful in booking a taxi (C15)”; “I do not need some people to use e-hailing apps (C52); “I believe e-hailing app is compatible with existing technology (C61).” The sub-criterion “E-hailing app service provider keeps its promise (C72)” was demonstrated to have the least impact on the user intention of adopting e-hailing apps.

Research limitations/implications

The study has been confined to only eight factors selected from the extended technological acceptance model framework and some related technology acceptance theories. Some more other factors may have an impact on user adoption of e-hailing apps, which need to be added further. Also, the scope of the study should be enhanced by expanding the geographical area beyond the selected region.

Practical implications

The findings of the study enable the e-hailing service providers and marketers to understand the users’ intention in a better way, to make improvements in e-hailing apps and formulate strategies accordingly.

Originality/value

The previous literature provides the base to the present study for identifying the factors affecting user behavioral intention toward e-hailing apps and information technology. The findings and results of the present research make value addition to the existing knowledge base.
Market orientation and firm performance: can there be too much of a good thing?
Authors: Jancenelle Vivien , Storrud-Barnes Susan F. , Buccieri Dominic
Published: July 2021

Purpose

Past research has generally purported that market orientation (MO) leads to superior firm performance, despite emerging evidence suggesting that the highest levels of MO are not always rewarded. Drawing on resource-based view and MO literature, the authors posit that too much MO may be as detrimental as too little for firms seeking to achieve better performance, and that moderate MO capabilities may be the most beneficial. Furthermore, the authors propose and test for organizational confidence as a first potential moderator of the MO-performance inverted U-shaped link.

Design/methodology/approach

The authors use Computer-Assisted-Text-Analysis (CATA) methodology assess constructs from annual reports matched with a 5-year longitudinal dataset of 2,245 firm-year observations drawn from the S&P 500.

Findings

The results not only support the presence of an inverted U-shaped link between MO and firm performance, but also identify organizational confidence as an important moderator of this newly uncovered curvilinear relationship.

Practical implications

When it comes to the effect of MO on firm performance, there can be indeed be “too much of a good thing,” and managers should be aware of the trade-offs that come attached with overcommitting to a MO strategy.

Originality/value

The authors contribute to extant research on the MO–performance link by moving beyond simple linear relationships and identifying an inverted U-shaped relationship between MO and firm performance. This newly found curvilinear relationship may explain and reconcile prior contradicting findings on the benefits of MO. Organizational confidence is also found to trigger a shape-flip of the MO–performance link, thereby suggesting a new boundary condition.
Productivity dispersion in the Italian knowledge-intensive business services (KIBS) industry: a multilevel analysis
Authors: Campisi Domenico , Mancuso Paolo , Mastrodonato Stefano Luigi , Morea Donato
Published: July 2021

Purpose

This paper aims to provide an analysis of the productivity evolution of a sample of 18,459 knowledge-intensive business services (KIBS) firms operating in Italy over the period 2012–2018. The interaction between productivity heterogeneity firm localization and firm sector of business are also analyzed.

Design/methodology/approach

The empirical setting is based on data envelopment analysis (DEA) to measure the multifactor productivity index (MPI) and on the multilevel models to investigate if the source of productivity heterogeneity among the Italian KIBS are due to the geographic location and/or to the specific business sectors in which firms operate. Data have been gathered from the AIDA database, which contains financial data of all Italian firms.

Findings

The empirical results show that MPI heterogeneity in the Italian KIBS firms' is sensitive to the regional context in which firms operate to the specific KIBS sector and above all at the interactions arising between region and sector.

Originality/value

The paper contributes to identify the source of productivity dispersion in the Italian KIBS.
The practices of Shariah governance systems of Islamic banks in Bangladesh
Authors: Alam Md. Kausar , Rahman Md. Mizanur , Islam Fakir Tajul , Adedeji Babatunji Samuel , Mannan Md. Abdul , Sahabuddin Mohammad
Published: July 2021

Purpose

The purpose of this study is to explore the practices of Shariah governance (SG) systems in terms of their guidelines, current operational procedures, internbal policies and structures and regulatory framework of Islamic banks in Bangladesh from the viewpoints of Shariah, Tawhidic approach/ontological approach and Shuratic process of Islamic corporate governance and institutional theory.

Design/methodology/approach

A semi-structured interview tactic has been applied to attain the objective. Overall, data has been collected from the regulators, Shariah supervisory board members, Shariah department executives and experts from the central bank and Islamic banks of Bangladesh.

Findings

The study finds that Islamic banks do not follow complete Shariah principles in all aspects of SG nor violate them fully in their overall functions due to less accountability, which contradicts the concept of the Tawhidi epistemological process of Islamic corporate governance. Islamic banks announce that they are following Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) guidelines, but in practice, they do not follow the instructions accurately because all of the standards and policies of AAOIFI and the Islamic Financial Services Board are not applicable in Bangladesh due to its cultural, legal and regulatory structures. It is found that Islamic banks in Bangladesh have a lower practice of maqasid as-Shariah and Tawhidic approach and Shuratic process.

Research limitations/implications

The study significantly contributed to the central bank of Bangladesh and Islamic banks by exploring the SG systems for their further enhancement. The research provides some suggestions for improving existing SG systems and enhancing more application of SG guidelines and Shariah principles in the overall operations of the Islamic banks in Bangladesh.

Originality/value

This research extends the literature regarding the Islamic banks’ SG practices in Bangladesh. The study also contributes to Shariah, Tawhidic approach/ontological approach and Shuratic process of Islamic corporate governance and institutional theory by exploring the Islamic banks’ existing SG practices in Bangladesh.
Dynamics of millennial employees' communicative behaviors in the workplace: the role of inclusive leadership and symmetrical organizational communication
Authors: Lee Yeunjae
Published: July 2021

Purpose

With a focus on millennial employees, this study investigates how employees engage in two types of employees' communicative behaviors (ECBs), that is, their voluntary communicative efforts to acquire and circulate tasks and managerial information (i.e. scouting) and to share and discuss positive and negative aspects of their organization with internal members (i.e. internal megaphoning). Through the lens of social exchange theory (SET) and symmetrical communication model, this study examines the effects of inclusive leadership and internal communication on active information behaviors of employees within their companies.

Design/methodology/approach

An online survey was conducted with fulltime millennial employees working across various industry sectors in the US.

Findings

Symmetrical internal communication influenced by inclusive leadership enhances employees' scouting behavior as well as positive internal megaphoning behavior. Positive and negative internal megaphoning with supervisors increases the scouting behavior of employees, whereas negative internal megaphoning with peers does not have a significant effect.

Originality/value

This study is among the first attempts to examine the effectiveness of leadership and strategic internal communication on millennial employees' diverse types of communicative behaviors.
Topology optimization for infill in MEx
Authors: Schmitt Matt , Kim Il Yong
Published: July 2021

Purpose

In furthering numerical optimization techniques for the light-weighting of components, it is paramount to produce algorithms that closely mimic the physical behavior of the specific manufacturing method under which they are created. The continual development in topology optimization (TO) has reduced the difference in the optimized geometry from what can be physically realized. As the reinterpretation stage inevitably deviates from the optimal geometry, each progression in the optimization code that renders the final solution more realistic is beneficial. Despite the efficacy of material extrusion (MEx) in producing complex geometries, select manufacturing constraints are still required. Thus, the purpose of this paper is to develop a TO code which demonstrates the incorporation of MEx specific manufacturing constraints into a numerical optimization algorithm.

Design/methodology/approach

A support index is derived for each element of the finite element mesh that is used to penalize elements, which are insufficiently supported, discouraging their existence. The support index captures the self-supporting angle and maximum allowable bridging distance for a given MEx component. The incorporation of the support index into a TO code is used to demonstrate the efficacy of the method on multiple academic examples.

Findings

The case studies presented demonstrate the methodology is successful in generating a resulting topology that is self-supporting given the manufacturing parameters specified in the code. Comparative to a general TO problem formulation, the optimal material distribution results in a minimally penalized design on a compliance normalization metric while fully adhering to the MEx specific parameters. The methodology, thus, proves useful in generating an infill geometry is fully enclosed regions, where support material extraction is not a possibility.

Originality/value

The work presented is the first paper to produce a novel methodology that incorporates the manufacturing-specific constraint of bridging distance for MEx into TO code. The results generated allow for the creation of printed components with hollow inclusions that do not require any additional support material beyond the intended structure. Given the advancement, the numerical optimization technique has progressed to a more realistic representation of the physical manufacturing method.
Broker-dealer leverage volatility and the US stock prices
Authors: Istiak Khandokar
Published: July 2021

Purpose

Broker-dealer leverage volatility increases during booms and crisis periods, but its impact on stock prices is relatively unexplored. This paper aims to investigate whether broker-dealer leverage volatility is a key driver for stock prices.

Design/methodology/approach

This paper collects the US quarterly data of broker-dealer book leverage and three leading stock market indicators (S&P 500, DJIA and Nasdaq) for the period of 1967–2018. The research uses a multivariate GARCH-in-mean VAR to examine the impact of leverage volatility on each of the stock market indicators. A split-sample analysis (pre-1990 and post-1990) has also been performed to show the robustness of the result.

Findings

The research finds that broker-dealer leverage volatility does not have any significant impact on stock prices.

Originality/value

Broker-dealers are important financial intermediaries, and there is a huge literature exploring the relationship between their leverage and asset prices. But, the relationship between broker-dealer leverage volatility and asset prices is not explored yet. This study fills the gap and provides the first evidence that broker-dealer leverage volatility does not play any major role in the theory of stock pricing. The research proposes that the stock holding decisions of the investors should depend only on the first moment of leverage and not on the second moment of leverage. The study concludes that high broker-dealer leverage volatility is not a sinister signal for the US stock market.
The impact of the intrapersonal, interpersonal and ecological factors on pre-service second language teachers' identity construction
Authors: El Masry Taghreed , Alzaanin Eman I.
Published: July 2021

Purpose

This article reports on the intrapersonal, interpersonal and ecological factors that shaped the professional identity (PI) construction of five ESL Malaysian pre-service teachers (PSTs) during microteaching classes and teaching practicum.

Design/methodology/approach

The study is qualitative in nature aiming to give voice to ESL PSTs and allow them share their personal experience while constructing their professional identity. The semi-interview data were supported by observation data to validate what PSTs report in their interview. The researchers chose junctural points in the PI construction journey to follow the developmental line of PI growth and to live the experience with the participant. The project was a co-construction of knowledge and enabled a more comprehensive understanding of the phenomenon.

Findings

This inquiry revealed that PI is dynamic and changing constantly as one reinterprets and reevaluates self and interact and react to the various intrapersonal, interpersonal and ecological factors in their context. At the intrapersonal level, lack of practical experience and intrinsic motivation and sense of low self-efficacy created a perception of low PI in the beginning of the simulated practice. The findings also show that supportive interpersonal relationships developed within a facilitating context such as the simulated teaching class smoothed the emergence of high PI. However, when the interpersonal relationships and ecological context in the practicum settings were challenging, they hindered PI development and led to a PI crisis.

Practical implications

The article offers recommendations to enhance the pivotal role of teaching practice during PSTs' journey of becoming.

Originality/value

This study was conducted in one of the understudied contexts in regards of PI construction. It captured a holistic view of the PI construction. It showed that the interplay of interpersonal and intrapersonal factors, in addition to ecological factors, is not isolated from each other. On the contrary, they were like a cycle circumscribing the PSTs and impact their PI construction. Hence, the authors believe that the study contributed with a comprehensive understanding of pre-service PI construction.
Is this mine? Psychological ownership and the social media follower
Authors: Tan Caroline S.L.
Published: July 2021

Purpose

The purpose of this study is to examine psychological ownership (PO) experienced by followers of social media influencers toward both influencer and the product.

Design/methodology/approach

Data were collected using face-to-face semi-structured interviews that were conducted with 30 respondents and analyzed using thematic analysis.

Findings

The study demonstrated that the PO experienced by the follower changes under different conditions resulting from perceived value, social currency and follower activity. Social currency plays a vital role in determining the target of PO, often affecting the narrative by the follower.

Originality/value

To the best of the author’s knowledge, this is the first paper to examine the transference of PO between product and influencer as experienced by the follower. It provides an understanding on PO that is experienced in different levels of intensity and changes depending on the motive of the follower; hence, transference of PO occurs and it is not a static.
Efficacy of hydroxychloroquine for treating annular erythema associated with Sjögren’s syndrome
Authors: Arakawa Hiroki , Tanese Keiji , Tanaka Ryo , Murakami Kaori , Sujino Kazuyo , Miyamoto Julia , Amagai Masayuki , Tanikawa Akiko
Published: July 2021

Annular erythema is one of the cutaneous manifestations of Sjögren’s syndrome (SS). Topical corticosteroids and tacrolimus, and oral corticosteroids, have been used as treatments for this condition. However, the safety and efficacy of these treatments remains unsatisfactory, and further development of therapies are desired. In this study, we performed a retrospective analysis of 16 annular erythema associated with SS (AESS) patients treated with hydroxychloroquine (HCQ). Disease activity was assessed using a modified version of the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI), which we termed the modified CLASI (m‐CLASI). HCQ treatment improved AESS lesions in all 16 patients. The mean m‐CLASI score was reduced by 85.6% at the 12‐week follow‐up relative to baseline (p < 0.01). Notably, 60% (6/10 cases) of patients with AESS lesions limited to the facial area achieved complete remission within 4 weeks. In the analysis of six patients who had taken oral prednisolone before starting HCQ, all were able to reduce the dose within 52 weeks without relapse. Particularly, 75% (3/4 cases) of patients with prednisolone dose of more than 5 mg/day could reduce their dose to less than 5 mg/day in combination with HCQ. For the safety concerns, two patients experienced grade 1 diarrhea during the 52‐week observation period. However, neither serious adverse events nor adverse events requiring discontinuation of treatment occurred. The results of the present study suggest that HCQ may not only be highly effective as a single agent, but may also be useful as a steroid‐sparing agent in refractory case requiring long‐term steroid administration, making it a good treatment option for AESS.
‘And I Hereby Declare the Runner‐Up to be the Winner’: The Extraordinary 2021 DUP Leadership Election
Authors: Tonge Jonathan
Published: July 2021

The first‐ever election for the leader of the Democratic Unionist Party (DUP) in May 2021 proved eventful in terms of both its instigation and outcome. Founded in 1971, the DUP's three previous leaders had either been self‐appointed (Ian Paisley, the party's founder) or nominated without a rival opponent (Peter Robinson and Arlene Foster). Foster's unseating in an internal coup triggered a contest between Northern Ireland Executive minister Edwin Poots and Westminster MP Sir Jeffrey Donaldson. The outcome was determined by one of the smallest selectorates of any party in the UK or Ireland, twenty‐eight DUP members of the Northern Ireland Assembly (MLAs) and the party's eight Westminster MPs. They voted narrowly to elect Edwin Poots as their new party leader. Yet, Poots lasted merely twenty‐one days in the job, replaced by Donaldson, who was unopposed when the leadership vacancy re‐arose. This article analyses an extraordinary saga.
The COVID‐19 pandemic and cause of death
Authors: Armstrong David
Published: July 2021

This article explores the emergence and development of Death Certificates as a means of establishing the cause of death for individuals and populations. The difficulty in choosing which disease caused death when several are described on the Certificate explains why the number of COVID‐19‐related deaths has been difficult to determine. This problem also draws attention to the dominant biomedical explanation for the cause of death that both promote and circumscribe what can be recognised as a valid cause.
Rehydration and restoration of fingerprint ridge detail in mummified post‐mortem tissue: Literature review and investigation of a simplified formulation
Authors: Marais Adriaan A. S. , van den Dool Adri H.
Published: July 2021

Mummified tissue presents challenges for fingerprinting due to rigidity, shrinkage, and other features obscuring epidermal ridge detail. A new cost‐effective in‐house solution was developed to obtain good quality fingerprints from mummified remains. The simplified procedure uses a sodium carbonate:sodium acetate mixture easily prepared using commonly available chemical products. An overview of the methods and solutions utilized to date for rehydration and restoration illustrates the main benefits of the developed formulation: the solution provided better tissue pliability and turgor than the sodium carbonate:ethanol formulation of Rüffer previously employed; the prepared solution proved stable for weeks at room temperature and poses minimum hazard risk to users. It functions as a weak base (pH 9.3) and is sufficiently corrosive to allow tissue softening over a flexible timeframe of 1–5 days without causing any damage. The degree of effectiveness for rehydration of mummified tissue and restoration of ridge detail is attributed to three synergistic aspects: increased turgor as provided by a penetrating humectant and water; softening and pliability as a result of pH and any specific chemical interaction that affects calcium in collagen; ridge detail definition as a function of turgor and softening, with some secondary corrosive dependency related to the pH of a solution.

Trait specialization often comes at the expense of original trait function, potentially causing evolutionary tradeoffs that may render specialist populations vulnerable to extinction. However, many specialized adaptations evolve repeatedly, suggesting selection favors specialization in specific environments. Some garter snake (Thamnophis) populations possess specialized mutations in voltage‐gated sodium channels that allow them to consume Pacific newts (Taricha) defended by a highly potent neurotoxin (tetrodotoxin). These mutations, however, also decrease protein and muscle function, suggesting garter snakes may suffer evolutionary tradeoffs. We measured a key physiological process, standard metabolic rate (SMR), to investigate whether specialized adaptations in toxin‐resistant garter snakes affect baseline energy expenditure. In snakes, skeletal muscles influence metabolism and power ventilation, so inefficiencies of sodium channels in these muscles might impact whole‐animal energy expenditure. Further, because sodium channels are membrane‐bound proteins, inefficiencies of channel kinetics and performance might be exacerbated at suboptimal temperatures. We measured SMR in 2 species, Thamnophis atratus and Thamnophis sirtalis, that independently evolved tetrodotoxin resistance through unique mutations, providing replicate experiments with distinct underlying genetics and potential physiological costs. Despite our expectations, neither resistance phenotype nor sodium channel genotype affected metabolism and resistant snakes did not perform worse under suboptimal body temperature. Instead, T. atratus and T. sirtalis show nearly identical rates of mass‐adjusted energy expenditure at both temperatures, despite differing eco‐morphologies, life histories, and distant phylogenetic positions. These findings suggest SMR may be a conserved feature of Thamnophis, and that any organismal tradeoffs may be compensated to retain whole‐animal function.
Vegetation cover and occurrence of salamanders in the western Mediterranean

The Mediterranean region possesses a rich diversity of salamanders, which also exhibit a high degree of ecological diversification. It is assumed that the presence of salamanders is dependent on the level of vegetation cover in terrestrial habitats, but the strength of this association is likely to vary among species. In this study, we investigated the patterns of habitat utilization for Mediterranean salamanders based on 589 records of 33 species. We tested the hypothesis that the association between salamander presence and vegetation density varies among genera or reproductive modes (i.e. terrestrial vs aquatic). The results show that vegetation cover has similar influences on terrestrial and aquatic groups but important differences are identified for lotic and lentic aquatic species. Our findings also indicate that the aquatic lotic, terrestrial, and small‐body species deviate significantly from that expected from the background range of variation.

In this study, we estimate consumers’ willingness to pay (WTP) for ready meals preserved using microwave assisted pasteurization systems (MAPS)—a novel pasteurization technology, compared to frozen, ready meals. We conducted a laboratory multi‐round experimental auction for two samples of ready meal jambalaya in which appearance and sensory evaluation along with extrinsic information was sequentially disclosed to panelists. Our results suggest that when participants tasted the meals and formed an opinion from the meal itself, the liking of appearance and sensory attributes were the most impactful factors for participants’ WTP regardless of other available extrinsic (name of the preservation technology and environmental impacts of each technology) attributes. The words “microwave” and “pasteurization” did not negatively impact the WTP. The order in which intrinsic and extrinsic attributes were evaluated and presented did not impact absolute WTP values, but the order did impact the weight of each attribute type on the WTP.

Practical Application

The sensory perceptions had a larger effect than the name of the preservation technology and environmental impacts on the willingness to pay (WTP) for ready meals. The order of presented information to panelists did not impact absolute values of WTP. The words “microwave” and “pasteurization” did not have a negative effect on WTP.

Exorbitant outputs of waste xylose mother liquor (WXML) and corncob residue from commercial‐scale production of xylitol create environmental problems. To reduce the wastes, a Saccharomyces cerevisiae strain tolerant to WXML was conferred with abilities to express the genes of xylose reductase, a xylose‐specific transporter and enzymes of the pentose phosphate pathway. This strain showed a high capacity to produce xylitol from xylose in WXML with glucose as a co‐substrate. Additionally, a simultaneous saccharification and fermentation (SSF) process was designed to use corncob residues and cellulase instead of directly adding glucose as a co‐substrate. Xylitol titer and the productivity were, respectively, 91.0 g l‐1 and 1.26 ± 0.01 g l‐1 h‐1 using 20% WXML, 55 g DCW l‐1 delignified corncob residues and 11.8 FPU gcellulose‐1 cellulase at 35° during fermentation. This work demonstrates the promising strategy of SSF to exploit waste products to xylitol fermentation process.
