Calpains are required for efficient microtubule detyrosination
Authors: Bär Julia , Popp Yannes , Koudelka Tomas , Tholey Andreas , Mikhaylova Marina 
Published: July 2021

AbstractDetyrosination is a major post-translational modification of microtubules (MT), which has significant impact on MT function in cell division, differentiation, growth, migration, polarity, and intracellular trafficking. Detyrosination of α-tubulin occurs via the recently identified complex of vasohibin 1/2 (vash1/2) and small vasohibin binding protein (SVBP). However, there is still remaining detyrosinating activity in the absence of vash1/2/SVBP, and little is known about the regulation of detyrosination. Using cellular and cell-free assays we showed that the calcium-dependent proteases calpains 1 and 2 regulate MT detyrosination. We identified new calpain cleavage sites in the N-terminal disordered region of vash1 using in vitro proteolysis followed by mass spectrometry. However, this cleavage did not affect the detyrosination activity of vasohibin. In conclusion, the regulation of MT detyrosination by calpains occurs via another yet unknown tubulin carboxypeptidase. Importantly, calpains’ calcium dependency could allow a fine regulation of MT detyrosination. Thus, identifying the calpain-regulated pathway of MT detyrosination can be of major importance for several basic and clinical research and should be focused on in future studies.Summary StatementThe conventional calpains 1 and 2 play an important role in the regulation of microtubule detyrosination in a vasohibin independent way. Thus, they possibly control another still unknown tubulin carboxypeptidase.

Published: July 2021

A description of the upgraded bunch-by-bunch feedback system for time-resolved experiments at Pohang Light Source II (PLS-II) is provided. The bunch-by-bunch feedback system has been upgraded to increase the single-bunch current in the hybrid fill pattern of the PLS-II facility. The project is part of the SPring-8 and PLS-II collaboration. The main features of the upgrade are to employ a single 500 MHz analog-to-digital converter (ADC) instead of the previous four 125 MHz interleaved ADCs for 500 MHz rate, to replace a single-loop two-dimensional feedback with two independent one-dimensional feedback loops, to implement the tune measurement function with a single bunch, and mainly to implement single-bunch and stretcher control. The realization of a 400 mA hybrid fill pattern including a 10 mA single bunch demonstrates the precision of the upgraded bunch-by-bunch feedback system.
Theoretical model proposal on direct calculation of wetted area and maximum lift-to-drag ratio
Authors: Durmus Seyhun 
Published: July 2021

Purpose
As measuring flight performance by experimental methods requires a lot of effort and cost, theoretical models can bring new perspectives to aircraft design. This paper aims to propose a model on the direct calculation of wetted area and L/Dmax.

Design/methodology/approach
Model is based on idea that the wetted area is proportional to aircraft gross weight to the power of 2/3 (Wg2/3). Aerodynamic underpinning of this method is based on the square–cube law and the claim that parasitic drag is related to the Swet/Swing. The equation proposed by Raymer was used to find the L/Dmax estimate based on the calculated wetted area. The accuracy of the theoretical approach was measured by comparing the L/Dmax values found in the reference literature and the L/Dmax values predicted by the theoretical approach.

Findings
Proposed theoretical L/Dmax estimate matches with the actual L/Dmax data in different types of aircraft. Among the conventional tube-wing design, only the sailplanes have a very low Swet/Swing. The Swet/Swing of flying wings, blended wing bodies (BWBs) and large delta wings are lower than conventional tube-wing design. Lower relative wetted area (Swet/Swing) is the key design criterion in high L/Dmax targeted designs.

Originality/value
The proposed model could be used in wing sizing according to the targeted L/Dmax value in aircraft design. The approach can be used to estimate the effect of varying gross weight on L/Dmax. In addition, the model contributes to the L/Dmax estimation of unusual designs, such as variable-sweep wing, large delta wings, flying wings and BWBs. This study is valuable in that it reveals that L/Dmax value can be predicted only with aspect ratio, gross weight (Wg) and wing area (Swing) data.

Published: July 2021

Purpose
Amid the expanding demand on the autism service delivery system, little knowledge is accumulated regarding access and availability of support and services in the region of Southern and South-Eastern Europe – critical for improvement of individual outcomes, as well as family quality of life. The purpose of this paper is to explore how service delivery systems are responding to the specific needs of autistic individuals with autism, as perceived by parents.

Design/methodology/approach
A qualitative exploratory descriptive method was used. Thematic analysis was used as a pragmatic method to report on the experiences of parents (92% mothers, n = 55) of children, youth and young autistic adults (76% male) across six South and South-Eastern European counties that participated in a survey involving a combination of qualitative and quantitative data collection.

Findings
Thematic analysis revealed three broad themes: challenging pathways to service utilization, insufficient service options and providers’ competences and lack of continuous and meaningful support across life span.

Originality/value
The findings from this study add to the small body of literature specific to South and South-Eastern Europe, by exposing problems related to meeting the needs of autistic children and youth and potential ways to strengthen services, as perceived by parents. The findings have potential policy ramifications for the region in which the research was conducted.
Why customers have the intention to reuse food delivery apps: evidence from China
Authors: Bao Zheshi , Zhu Yun 
Published: July 2021

PurposeFood delivery apps (FDA) have been widely adopted by customers in online-to-offline (O2O) catering businesses. This study aims to explore the mechanism regarding the stickiness of FDA and indicates why customers have the intention to reuse them.Design/methodology/approachA research model was developed based on the e-commerce system successful model (ECSS model) and social influence theory. Using the data collected from 312 customers who have FDA usage experience via an online survey, the established model was empirically assessed by partial least squares based structural equation model.FindingsThe results show that factors including information quality, ease of use, convenience and various choices perceived by FDA users are significant antecedents of customer satisfaction and perceived value, which in turn positively influence customers' intention to reuse. Besides, informational social influence and normative social influence play important roles in directly or indirectly affecting customers' intention to reuse.Originality/valueThis study extends the e-commerce system success model and enriches the literature regarding stickiness of FDA. Besides, the understanding of social influence in FDA usage has been deepened by addressing its role in the ECSS model based on the features and contexts of such apps.

Study level/applicability
This case is appropriate for the following courses in undergraduate, graduate or executive programs.

Subject area
Sustainability, strategy, inclusive business, environmental sustainability and women in leadership. Upon completion of the case study discussion successful students will be able to:

Case overview
Bilikiss Adebiyi-Abiola brought to life Wecyclers, an urban waste management company in Nigeria that started as an idea during her MBA programme at MIT. Bilikiss served as its CEO from 2012 and mobilized efforts to sign up thousands of individuals, corporate bodies and agents who turn in waste to recycle. While waste management already had a lot of private sector participants (PSPs), there was no recycling company with a focus on community engagement as at the time Wecyclers came on board. The company went through several iterations to arrive at business model, develop its peculiar infrastructure, build partnerships and raise funds. The case study documents Wecyclers roll-out under the leadership of Bilikiss, whose work with Wecyclers has been shaped by her evolution as a professional woman with a background, education and network that has enabled her excel in the face of social norms which emphasize men as leaders. The case dilemma involves strategy cross-roads Bilikiss faced in mid-2017 as Wecyclers considered expanding its operation, pushed beyond waste collection, pushed by infrastructural weaknesses in the landscape which forced the company to consider vertical integration of its inclusive business model as a way forward to meaningfully serving its stakeholders – from communities, corporates to agents.

Expected learning outcomes
• Explore the strategic contexts of doing business in emerging markets;• understand the challenges and opportunities in inclusive business model for solving a social problem such as waste management; and • Examine the growth and evolution of women’s leadership, possibilities and hurdles, in a range of contexts.

Supplementary materials
Teaching notes are available for educators only.

Social implications
In this way, the case study contributes to the limited body of knowledge about strategic and pragmatic facing social enterprises in emerging markets, including funding, community engagement, infrastructure, etc. It also gives us a view of inclusive business models and the evolution of women’s leadership.

Discussing the potential of the institutional theory to leverage service-dominant logic advancements
Authors: Gonçalves Sara Martins , Silva Rui Vinhas 
Published: July 2021

Purpose
Institutions play a central role in service-dominant logic. However, the discussion regarding how institutional theory supports service-dominant logic advancements is still insufficient. This paper aims to contribute to a discussion on the multiple service-dominant logic approaches to institutions.

Design/methodology/approach
This conceptual paper presents the characterization of the existing streams in the broad institutional literature, highlighting the differences among those streams and elaborates on how one of the discussed streams – neo-institutionalism – is suitable to support service-dominant researchers in understanding the role of institutions in markets and value co-creation.

Findings
The paper shows that the three institutional perspectives presented are used indistinctly by service-dominant logic and a greater fit between the service-dominant logic and the neo-institutionalism stands out.

Originality/value
The paper proposes that service-dominant researchers should look at the neo-institutional stream as a particularly fertile ground for furthering their research.
Exploring conflicts between stakeholders in tourism industry. Citizen attitude toward peer-to-peer accommodation platforms
Authors: Martín Martín José María , Prados-Castillo Juan F. , de Castro-Pardo Mónica , Jimenez Aguilera Juan De Dios 
Published: July 2021

Purpose
The expansion of online platforms for renting tourist accommodations has given rise to a great deal of controversy in society. Likewise, the arrival of tourists in residential settings has led to a wide range of positive and negative impacts, resulting in conflicts between different stakeholders. The purpose of this paper is to analyze whether there is variation in the perception of the impacts associated with peer-to-peer accommodation platforms among different stakeholders? Additionally, it also seeks to investigate what kind of impacts generate the highest level of conflict among stakeholders?

Design/methodology/approach
Given the relative novelty of the problem, this paper proposes an exploratory study that sheds light on some of the main issues with the purpose of supporting further research in the future. The aim is to analyze which impacts are perceived as more positive or negative by each group and to create indexes of conflict for these groups regarding their perception of the impacts. This study is based on fieldwork carried out in April 2020, which consists of 600 online surveys of local residents in the city of Granada. This city, one of Spain’s main tourist spots, suffers the highest tourist pressure in the country.

Findings
The exploratory study suggests that the greatest consensus is generated in the assessment of economic impacts, either negative or positive. The greatest conflicts are related to the assessment of the effect of this activity on housing preservation. The group comprising accommodation owners of tourist flats is the one that shows a more dissenting opinion from the rest, confronting especially the group formed by citizens whose income depends on tourism.

Originality/value
There is a lack of studies on the perception of tourism impacts associated with online tourism rental platforms. This is the first study to analyze both, how the main stakeholders associated with this activity assess the different impacts derived from this form of tourist accommodation as a whole and the conflicts derived from such an assessment. An additional innovation is that the analysis investigates the potential fear of disease transmission caused by tourists. It would be interesting to continue this research by applying the same questionnaire in different environments, such as rural areas or societies with different structures from the one analyzed here. Likewise, future in-depth analysis of some of the conflicts is recommended so as to ascertain their origin.
Why some leaders qualify for hate: an empirical examination through the lens of followers’ perspective
Authors: Sharma Gunjan , Kulshreshtha Kushagra 
Published: July 2021

Purpose
The leaders’ perception about self and the opinion of the subordinates about them is crucial to understand why some leaders qualify for hate. Much has been discussed on the positive and ethical side of leadership. However, the research on the darker side of leadership needs more attention. Therefore, the purpose of this paper is to explore the factors along with their impact responsible for hate-for-leaders, a relatively scant area of leadership. This study may facilitate understanding why some leaders become subject to hate despite many efforts by the organization.

Design/methodology/approach
For exploring the different factors responsible for hate-for-leaders, a survey was conducted by developing a scale using the focus group, Delphi technique, exploratory factor analysis and confirmatory factor analysis. The results were analysed using structural equation modelling.

Findings
The factors responsible for qualifying the leaders for hate were identified. Moreover, the results indicated that the subordinate hate the leaders for his/her unacceptable behaviour/actions which they assume the leader has control over it and exhibited otherwise intentionally on targeted employees. Moreover, some undesirable behaviour of leaders is attributed to fundamental attribution errors i.e. situational factors.

Practical implications
A fully developed scale for assessing the hate-quotient for leaders is proposed. This research will facilitate the managers/leaders as to why some of the followers/employees hate them. This scale provides an opportunity for managers and leaders to introspect themselves for improved workplace relationships and not to encourage sunflower management that seeks to get submissive and aligned-thought employees around the leader.

Originality/value
The fact that the decisions taken by managers/leaders adversely affecting the employees are not always because of malice or wrong intentions but sometimes due to situational factors i.e. fundamental attribution error. Moreover, the scale act as a reference to evaluate the hate-for-leaders in the organizational context.
The effects of professionalism and behavior by organizational citizenship (OCB) as mediating variables on the effect of personality on performance (a study on Makassar Police)
Authors: Nurrohmat Noviana 
Published: July 2021

PurposeThis study aims to determine the effect of personality on professionalism.Design/methodology/approachThis research was conducted in Makassar Police Office in Makassar City. The reason for conducting the research in the police officer was the low performance of police officers in Makassar Police while the workload was very high. The population in this study were all 1,185 police officers in Makassar Police Office. Using the probability sampling technique, there were 299 police officers selected as respondents. Further, this study employs descriptive statistical analysis and inferential statistical analysis using generalized structure component analysis (GSCA) as data analysis methods.FindingsThe result found that there is a significant effect of personality on professionalism and OCB. Different results are obtained on the effect of personality on performance, which has no significant effect. However, there is an indirect effect of personality on performance through professionalism and OCB as mediating variables. The results also found that there is a significant influence between Professionalism on OCB and performance, as well as a significant influence between OCB on Performance.Originality/valueThis study focus to determine the effect of personality on professionalism. It has never been done before, so this study will contribute a new empirical explanation on both relationships. In addition to differences in the use of constructs and measurements, this research is also different in terms of the analysis unit. This study examines the effect of organizational citizenship behavior (OCB) on the performance of members/employees. This research is different from previous researches which generally examine the effect of OCB with group performance such as performed by George and Bettenhausen (1990), Podsakoff et al. (1997), which both found a close association between OCB and group performance. This study examines the performance of individual members because the tasks of members of the police force require professional ability in individuals who are expected to give a good image to the police in general.
How management education is engaging students in the sustainable development goals
Authors: Weybrecht Giselle 
Published: July 2021

PurposeThis paper aims to explore if, and how, business schools globally have been engaging their students in the Sustainable Development Goals (SDGs), both inside and outside the classroom, since the SDGs were agreed upon in 2015 until mid-2020.Design/methodology/approachThe data is collected from information submitted as part of reporting requirements to the United Nations Principle for Responsible Management Education over the time in question. This paper outlines the range of approaches being reported on which specifically relate to students and explicitly mention the SDGs.FindingsThe results show that although there are a growing number of innovative approaches that could become the basis for the way management education approaches the SDGs moving forward, the majority of schools are not engaging their students in the SDGs. Of those schools that are, most offer limited evidence of it being embedded into the core of what students are learning or of it being approached in an interdisciplinary way. Business graduates are not being exposed to the SDGs in a way that connects them to “business as usual”. This is a missed opportunity for the students, the universities and the global community, given the important influence that management education, and the business sector by extension, has the realisation of the goals.Originality/valueThe results can help inform and inspire higher education institutions to engage students in the SDGs. A methodology to measure the degree of engagement is presented, which can then be used as a tool to benchmark progress.
The role of cultural values in consumers' evaluation of online review helpfulness: a big data approach
Authors: Filieri Raffaele , Mariani Marcello 
Published: July 2021

PurposeOnline consumer reviews are increasingly used by third-party e-commerce organizations to shed light on the positive and negative sides of the brands they sell. However, the large number of consumer reviews requires these organizations to shortlist the most helpful ones to cope with information overload. A growing number of scholars have been investigating the determinants of review helpfulness; however, little is known about the influence of cultural factors in consumer's evaluation of review helpfulness.Design/methodology/approachThis study has adopted Hofstede's cultural values framework to assess the influence of cultural factors on review helpfulness. We used a sample of 570,669 reviews of 851 hotels published by reviewers from 81 countries on Booking.com.FindingsFindings reveal that reviewers from cultural contexts that score high on power distance, individualism, masculinity, uncertainty avoidance and indulgence are more likely to write helpful reviews.Originality/valueThis is one of the first cross-cultural studies in marketing using a big data approach in examining how users of reviews from different countries evaluate the helpfulness of online reviews.
