An investigation on the influence of sintering temperature on microstructural, physical and mechanical properties of Cu-SiC composites
Authors: Somani Nalin , Tyagi Y. K. , Gupta Nitin Kumar 
Published: December 2021

Purpose
The purpose of this study is to investigate the effect of the sintering temperature on the microstructural, mechanical and physical properties of Cu-SiC composites.

Design/methodology/approach
The powder metallurgy route was used to fabricate the samples. Cold compaction of powders was conducted at 250 MPa which was followed by sintering at 850°C–950°C at the interval of 50 °C in the open atmospheric furnace. SiC was used as a reinforcement and the volumetric fraction of the SiC was varied as 10%, 15% and 20%. The processed samples were metallurgically characterized by the scanning electron microscope (SEM). Mechanical characterization was done using tensile and Vickers’ micro-hardness testing to check the hardness and strength of the samples. Archimedes principle and Four-point collinear probe method were used to measure the density and electrical resistivity of the samples.

Findings
SEM micrograph reveals the uniform dispersion of the SiC particles in the Cu matrix element. The results revealed that the Hardness and tensile strength were improved due to the addition of SiC and were maximum for the samples sintered at 950 °C. The addition of SiC has also increased the electrical resistivity of the Cu-SiC composite and was lowest for Cu 100% while the relative density has shown the reverse trend. Further, it was found that the maximum hardness of 91.67 Hv and ultimate tensile strength of 312.93 MPa were found for Cu-20% SiC composite and the lowest electrical resistivity of 2.017 µ- Ω-cm was found for pure Cu sample sintered at 950 °C, and this temperature was concluded as the optimum sintering temperature.

Research limitations/implications
The powder metallurgy route for the fabrication of the composites is a challenging task as the trapping of oxygen cannot be controlled during the compaction process as well as during the sintering process. So, a more intensive study is required to overcome these kinds of limitations.

Originality/value
As of the author’s best knowledge, no work has been reported on the effect of sintering temperature on the properties of the Cu-SiC composites which has huge potential in the industries.
A broad analysis of short-term overreactions in the market for cryptocurrencies
Authors: Kellner Tobias , Maltritz Dominik 
Published: December 2021

PurposeThe purpose of this study is to analyze market inefficiencies in the market for cryptocurrencies by providing a comprehensive analysis of short-term (over)reactions that follow significant price changes of such currencies.Design/methodology/approachThis study identifies and analyzes overreactions and mispricing in markets for cryptocurrencies by applying a broad set of thresholds that depend on market-specific dynamics and volatilities. This study also analyzes the returns on days following abnormal returns and identifies significant differences from normal returns using the t-test and the Mann–Whitney U-test. The researchers further complement the literature by using end-of-the-day returns in addition to high-low returns. Additionally, this study considers a broad sample of 50 cryptocurrencies for an expanded time span (2015–2020) that includes the big currencies as well as smaller currencies.FindingsFindings detect the existence of overreactions and, thus, market inefficiencies in crypto markets. The findings for different methodological approaches are similar, which underpins the robustness of the findings. By considering a broad sample that includes small and big currencies, we can show the existence of a market size effect. By considering a broad set of thresholds, the authors further found evidence for a magnitude effect, which means that higher initial abnormal returns are related to higher inefficiencies.Practical implicationsThis paper has practical implications. Market inefficiencies were detected, which can be used in practical trading to obtain excess returns. In fact, methodological approach of this study and its results can be used to derive a strategy for trading in cryptocurrencies that can be easily implemented. Based on the study’s findings, the authors can expect positive access returns by applying this trading strategy.Originality/valueThe authors complement the literature on market inefficiencies and mispricing in crypto markets by analyzing price patterns after initial abnormal returns. Researchers contribute by applying different methodological approaches in addition to the approaches used so far, by considering a set of different thresholds and by applying a much broader data set that enables the study to analyze additional aspects.
Rhetorical history and strategic marketing: the example of Starbucks
Authors: Volle Pierre 
Published: December 2021

Purpose
This study aims to illustrate how firms engage in rhetorical history, i.e. “the process by which managers skillfully impose meaning on a firm’s past as a persuasive and agentic process” (Suddaby et al., 2010). The case study shows that the connection of past events to specific and schematic narratives allows external events to be appropriated and used by Starbucks as assets to achieve its organizational goals (e.g. legitimacy).

Design/methodology/approach
The study is based on a close reading and coding of 1,852 “stories” (2,470 pages) published by Starbucks between 2003 and 2020.

Findings
The authors first show that Starbucks’ language relies heavily on terms referring to temporality. The authors then highlight the organization’s efforts to assert its history, to emphasize its heritage and to inscribe itself in local and national histories. With this case study, the authors contribute to the ongoing debate on history as an organizational resource. The study shows how brands that are not necessarily “historical” can mobilize rhetorical history in their strategic marketing.

Research limitations/implications
This case study illustrates four heritage implementation strategies: narrating, visualizing, performing and embodying. Further research could contribute to the discussion of rhetorical history production practices, in particular how heritage elements are validated, articulated, related and adopted by organizations (Burghausen and Balmer, 2014).

Originality/value
The research shows that the main mechanism for constituting social memory assets does not lie in the accumulation of narratives, but in the coupling of narratives at different levels, and in the inclusion of several stakeholders within the narratives. The research also highlights that the affirmation of the historicity of the firm is a prerequisite for the constitution of social memory assets. The research shows that there are a wide variety of ways to convey historical narratives, in particular the essential role leadership plays in the rhetorical process of historicization. The research also shows that the issues of identity and legitimacy are more closely linked than previous research has suggested. In a way, rhetorical history serves strategic management as much as marketing. The porosity between the different audiences allows for a strong alignment between stakeholders, thus consolidating a competitive advantage that lies at the heart of Starbucks’ success, and which notably contributes to reinforcing its core value proposition (i.e. access to a “welcoming, safe and inclusive” third place) and its relational business model. Finally, the case shows that the mobilization of social memory assets does not necessarily lead to the use of nostalgic associations. In this case, for Starbucks, it is not a matter of cultivating memories of the “good old days” but of drawing inspiration from the past, of maintaining traditions to remain culturally relevant and of relying on these assets to project itself into the future.

Impact on staff attitudes of brief personality disorder training for acute psychiatric wards
Authors: McDonald Claire , Seaman-Thornton Fiona , Mok Che Ling Michelle , Jakobsen Hanne , Riches Simon 
Published: December 2021

Purpose
Negative attitudes towards “personality disorder” are common among mental health professionals. This study aims to design a psychoeducational training targeting attitudes to “personality disorder” for staff working in a London psychiatric hospital. Its impact on staff attitudes was evaluated.

Design/methodology/approach
Mental health clinicians were recruited from five acute psychiatric wards. Feasibility of implementing the training was measured. A free-association exercise explored baseline attitudes to “personality disorder” and visual analogue scales assessed staff attitudes pre- and post-training. Content analysis of staff feedback was carried out.

Findings
Psychoeducational training was found to be feasible, well-attended and highly valued by ward staff (N = 47). Baseline results revealed negative perceptions of “personality disorder”. Post-training, significant improvements in understanding, levels of compassion and attitudes to working with service users with a diagnosis of a “personality disorder” were observed. Staff feedback highlighted desire for further training and support.

Research limitations/implications
The sample size was relatively small and there was no control group, so findings should be interpreted with caution.

Practical implications
The findings highlight the need for support for staff working with service users with diagnoses of “personality disorder” on acute psychiatric wards. Providing regular training with interactive components may promote training as a resource for staff well-being. Planning to ensure service users’ and carers’ views are incorporated into the design of future training will be important.

Originality/value
This study is innovative in that it investigates the impact of a brief psychoeducational training on “personality disorder” designed for mental health staff on acute psychiatric wards.
COVID fear and work-family conflict: a moderated mediated model of religiosity, COVID stress and social distancing
Authors: Naveed Shabana , Lodhi Rab Nawaz , Mumtaz Muhammad Usman , Mustafa Faisal 
Published: December 2021

Purpose
Based on the arguments of conservation of resource theory (COR), this study aims to investigate the mechanism underlying the linkage of COVID fear, work-family conflict (W-FC) and family-work conflict (F-WC) while investigating the mediating role of COVID stress and social distancing. The study also tests the moderating role of religiosity in these relationships.

Design/methodology/approach
In total, 401 survey responses from doctors and university teachers are collected through online and personally administrated questionnaires. Partial least square-based structural equation modeling technique is applied using Smart PLS software.

Findings
This study finds that COVID fear has a positive and significant impact on COVID stress and social distancing while religiosity negatively impacts COVID fear. Further, COVID stress and social distancing mediates the relationships between COVID fear and W-FC/ F-WC. However, the study found that COVID stress is a more effective mechanism as compared to social distancing in explaining the mediation process. It is also found that religiosity significantly moderates the nexus between COVID stress and both W-FC and F-WC negatively.

Practical implications
Findings imply that the teachers, as well as doctors, must be immediately be provided with the proper facilitation to maintain their work from home operations with the best of the institutional facilities. Moreover, the recruitment policy in such professions can also consider religious practices to be the indicators of problem-solving and stress management in such a challenging context.

Originality/value
This study provides timely and novel insight into the interplay between the domains of work and family during the period of stressful COVID outbreak. By distinguishing W-FC and F-WC, it provides a detailed understanding of the process during the COVID period. The groundbreaking finding in the research is with the moderation of religiosity.
Optimization and analysis of dry sliding wear process parameters on cellulose reinforced ABS polymer composite material
Authors: S. Ponsuriyaprakash , P. Udhayakumar , R. Pandiyarajan 
Published: December 2021

Purpose
This study aims to the optimization using three factors and three-level parameters (sliding speed [rpm], sliding distance [m/s] and load [N]) of design matrix were adapted to Box–Behnken design using design expert v8.0 software. Based on the parameters, to develop the linear regression equation and to find the significant considerable wear process parameters based on output responses like wear loss (WL) and coefficient of friction (COF) value of polymer matrix composites (PMC) specimen of Acrylonitrile-butadiene-styrene (ABS)/cellulose composite (80 wt% of ABS and 20 wt% of cellulose).

Design/methodology/approach
The fabrication of the ABS/cellulose composite sample was carried out by the simple hands-on stir process method. As per the American Society for Testing and Materials G99 standard, the sample was made by the molding process. The wear analysis was made by multi tribotester TR25 machine and validated the developed model by using statistical software design expert v.8.0 and numerical tools like analysis of variance. The surface morphology [field emission scanning electron microscopy (FESEM) analysis] of the sample was also observed using the Quanta FEG-250 FESEM instrument.

Findings
The parameters like sliding speed, sliding distance and load are independently affected the COF value and WL of the 80% of ABS matrix and 20% cellulose reinforced composite material. The regression equations were generated by the coefficient of friction value and WL, which predicted the minimum WL of 80% of ABS matrix and 20% of cellulose reinforced composite material. The worn surface analysis result exposes the worn path and equal distribution of reinforcement and matrix on the surface of composite material.

Originality/value
The literature survey revealed a small number of studies available regarding wear analysis of ABS matrix and cellulose reinforced composite materials. In the present work, to fabricate and evaluate the wear performance of PMC (80% of ABS and 20% of cellulose) depends on the WL and COF value. The maximum and minimum COF value (µ) of 80% of ABS and 20% of cellulose composite material is 4.71 and 0.28 with the optimized wear process parameter by 1,000 mm of sliding distance, 0.25 (m/s) of sliding speed and 9 N of load.
An empirical study on entrepreneurial traits and their impact on enterprise success
Authors: Pattanayak Sthitaprajnya , Kakati Munindra 
Published: December 2021

Purpose
Enterprise success is driven by enterprise actions, which, in turn, is influenced by entrepreneurial behaviours. Behaviours are guided by traits. Hence, it is highly likely that personality traits of entrepreneur are critical to enterprise success. This paper aims at finding the relationship between entrepreneurial traits and enterprise success, identify underlying construct and examine how successful and unsuccessful entrepreneurs differ across traits. It also attempts enterprise profiling based on these traits and test predictive validity of entrepreneurial traits on enterprise success.

Design/methodology/approach
In this study, 396 micro, small and medium enterprises comprising both successful and unsuccessful ones are studied together across 11 personality traits. Data was analysed using various statistical techniques like co-relation, t-test, factor analysis, cluster analysis and regression to test hypothesis and arrive at given findings.

Findings
This study finds there is strong positive co-relations between traits and enterprise success. It establishes that successful and unsuccessful enterprises display distinct traits and significantly differ from each other. Entrepreneurial traits affect enterprise success, and the former has significant predictive value on the later (R-squared = 0.866).

Practical implications
The findings have implications to entrepreneurs in relation to enriching the existing traits and inculcating new ones. Financial institutions like banks can peruse the findings and include traits and behavioural aspects in borrower selection, credit appraisal, evaluation and credit decisioning, to make it more holistic. It also generates scope for further academic research.

Originality/value
This study contributes to existing literature and validates existing findings. It also finds that traits are contagious in nature, together of which can be grouped to build an entrepreneurs’ traits index which exerts strong influence on enterprise success.

Authors: Walsh Philip , Singh Ranjita 
Published: December 2021

PurposeThis study aims to investigate the evolution of factors that influence the current and future use of video streaming applications by Millennial consumers.Design/methodology/approachCombining technology acceptance, perceived values and user identity theory this study used factor analysis and multiple regression to examine data from a survey of 292 university undergraduates.FindingsMillennial’s current and future use of video streaming services remains driven more by social and emotional values and their effect on identity salience with their choice of content. Ease of use, convenience and monetary value remains less of an influence currently but may become more important in the future with the continued maturity of the industry.Practical implicationsThe results of this study suggest that video streaming service providers should be developing business models that recognize the increasing importance of emotional appeal and self-identity of their service offerings as the industry matures and competition increases.Originality/valueThe research is novel in addressing future video streaming service provision by examining changes in young consumer behaviour over time within a similar sample population and considering the growth and technological advancement of video streaming services. The results are significant in addressing the gap that exists in understanding whether perceived values for technology adoption of the same product or service by millennials change over time and the implications that have for product and service providers.
What approach and avoidance factors drive Gen-Z consumers to buy bubble tea? An exploratory study
Authors: Istijanto Istijanto , Handoko Indria 
Published: December 2021

Purpose
Bubble tea has become a popular beverage among the Gen-Z population in recent years, not only in Asia where this beverage originated, but also worldwide. This research aims to understand the motivational factors of Gen-Z consumers in Indonesia in purchasing bubble tea products.

Design/methodology/approach
This research adopts a qualitative methodology by interviewing 22 Gen-Z consumers living in Indonesia. A thematic-analysis approach and NVivo software are applied for the data analysis.

Findings
Eight factors, i.e. taste, texture, packaging, store, price, health, trend and brand, play important roles in explaining how the emotional dimensions (pleasure, arousal and dominance) created by the environmental stimuli of bubble tea were approached or avoided within the purchasing behaviors of Gen-Z consumers. This study also identified affiliation behaviors as the result of interactions between the three dimensions.

Research limitations/implications
As a qualitative study, this research used a particular and limited context to gain insights. Hence, a broader scale of research using a quantitative approach is recommended to validate the factors influencing purchasing behavior among the Gen-Z population.

Practical implications
This study can help practitioners to gain a better understanding of Gen-Z consumers’ behaviors on beverage products and to formulate effective marketing strategies.

Originality/value
To the best of the authors’ knowledge, by adopting a qualitative approach, this study is among the first to explore more deeply the emotional dimensions that drive Gen-Z’s decisions regarding whether to purchase a bubble tea product or not.
From crypsis to masquerade: Ontogeny changes the colour defences of a crab spider hiding as bird droppings
Authors: Yu Long , Xu Xin , Li Fan , Zhou Wei , Zeng Hua , Tan Eunice J. , Zhang Shichang , Li Daiqin 
Published: December 2021

Abstract

Selection imposed by visually hunting predators has driven the evolution of colour‐based antipredator defence strategies such as crypsis, masquerade, mimicry and aposematism. Individuals of many animals are generally considered to rely on a single type of defence strategy, but individuals of some species use multiple colour‐based defences. Many animals switch between colour‐based defences against visually hunting predators during ontogeny. However, why this occurs remains poorly understood.

The crab spider Phrynarachne ceylonica is an often‐cited example of a bird dropping masquerade. It has recently been demonstrated that P. ceylonica crab spiders gain protection from their predators by being misidentified as bird droppings by their predators. P. ceylonica females show an ontogenetic shift in colour defences: early instars possess a dark and cryptic form, while at later instars and as adults, the spiders resemble bird droppings. We hypothesised that this shift may be driven by differential changes in predation risk of two defence strategies with increasing body size due to ontogeny.

We tested this hypothesis by presenting naïve domestic chicks with 3D printed artificial spiders of two different sizes (small, large) and two colours (dark, bird dropping‐like), and determined whether larger bird dropping‐like spiders are more readily found and attacked than cryptic forms by chicks. We found that small cryptic spiders were more difficult to detect than small bird dropping masquerading spiders, but large cryptic spiders were attacked much more quickly and more frequently than large bird dropping masquerading spiders.

Increasing predation pressure on larger, cryptic spiders during ontogeny suggests that switching to bird dropping masquerade may be a more effective defence as spiders increase in size. We thus conclude that the ontogenetic shift from crypsis to masquerade is adaptive.
