Published: September 2021

AbstractSperm chromatin is typically transformed by protamines into a compact and transcriptionally inactive state. Flowering plant sperm cells lack protamines, yet have small, transcriptionally active nuclei with chromatin condensed by an unknown mechanism. Here we show that a histone variant, H2B.8, mediates sperm chromatin and nuclear condensation in Arabidopsis thaliana. Loss of H2B.8 causes enlarged sperm nuclei with dispersed chromatin, whereas ectopic expression in somatic cells produces smaller nuclei with aggregated chromatin, demonstrating that H2B.8 is sufficient for chromatin condensation. H2B.8 aggregates transcriptionally inactive AT-rich chromatin into phase-separated condensates, thus achieving nuclear compaction without reducing transcription. H2B.8 also intermixes inactive AT-rich chromatin and GC-rich pericentromeric heterochromatin, altering higher-order chromatin architecture. Altogether, our results reveal a novel mechanism of nuclear compaction via global aggregation of unexpressed chromatin. We propose that H2B.8 is a flowering plant evolutionary innovation that achieves nuclear condensation compatible with active transcription.Abstract Figure
Factors affecting consumer purchasing behavior of functional food: a comparative analysis for consumer management
Authors: Salvatore Fiorella Pia , Adamashvili Nino , Contò Francesco 
Published: September 2021

PurposeThe main aims are underlining the role of functional foods (FFs) for population wellbeing, investigating the reasons in the self-consciousness of the different countries' populations and exploring what influences in purchasing decisions to address the management of food-producing businesses. This information will make consumer management easier.Design/methodology/approachA two-step methodology was adopted: (1) literature review and (2) online interview. The principal component analysis (PCA) was used to facilitate and reduce the data complexity. Software Stata/SE was used for data analysis in both Italy and Georgia.FindingsCustomers' attitudes, awareness level and decision-making process are clarified through the comparative analysis between Italian and Georgian populations. They have a number of reasons that incentivize their behavior. These reasons may be used by food-producing businesses to evaluate their performance and develop ad hoc strategies for consumer management.Originality/valueThe key elements that determine the FF and motivate the consumer to buy can constitute a foundation for actions related to the development and management of food-producing businesses. Knowing the factors that consumers consider in the process of choosing FFs will help define the strategies that businesses should use for product improvement, better managing the consumer. This study can support the development of education, prevention and promotion of managerial improvements. The innovative mixed methodology applied to the topic is one of the original factors of the study.
Assessing the efficiency of the Covid-19 control measures and public health policy in OECD countries from cultural perspectives
Authors: Min Hokey , Lee C. Christopher , Joo Seong-Jong 
Published: September 2021

PurposeTo identify sources of the success and failure of COVID-19 control measures and develop best-practice public health policy in mitigating the spread of COVID-19, this paper aims to evaluate the efficiency of various combinations of government COVID-19 control measures among OECD countries. This paper also identifies which factors critically influence the efficiency of COVID-19 control measures.Design/methodology/approachThis paper employed two-stage network SBM (slacks-based measure of efficiency) models with variable returns-to-scale and constant returns-to-scale, respectively, among various forms of data envelopment analysis (DEA) models. As a post hoc analysis, the authors used Tobit regression for examining the causal relationship between a nation's cultural dimensions and its COVID-19 control measure's efficiency scores.FindingsThe authors found that the pervasive less individualistic and higher uncertainty avoiding culture positively influenced the efficient control of COVID-19 outbreaks since such a culture helped the government impose its mandatory COVID-19 control measures without people's strong resistance to those measures.Originality/valueMany public health policymakers are wondering why COVID-19 control measures are not effective in coping with the COVID-19 outbreaks. This paper helps the government find the most efficient combination of COVID-19 controls measures for curbing the spread of the stubborn coronavirus. This paper is one of the first attempts to identify pandemic risk mitigation factors from a cultural perspective.
Can we talk? Why employees fail to report negative events to their managers
Authors: Scrimpshire Alex J. , Lensges Marcia L. , Webster Brian D. , Crosby Durand H. 
Published: September 2021

PurposeThe purpose of this research is to understand why and under what conditions employees are likely to partake in a particular type of silence, known as the Hierarchical MUM Effect (HME). This phenomenon occurs when subordinates are reluctant to share bad news with their supervisors, which can lead to deleterious outcomes in organizations due to a lack of communication. The authors also seek to find which conditions minimize HME.Design/methodology/approachThe authors surveyed employees in a large healthcare organization across three weeks. The authors analyzed their results using the SPSS PROCESS macro.FindingsThe authors’ findings suggest one way to minimize a lack of upward communication is to empower employees, via a high-quality LMX relationship, and move away from a bottom-line mentality focus. Employees who are empowered show lower instances of withholding information via HME. A low bottom-line mentality enhanced this relationship.Originality/valueThe authors expand understanding of antecedents to a particular type of silence, the HME, defined as purposefully withholding information from a supervisor or sharing information in a way that silences the dirty details of a situation (i.e. equivocating). Although a wealth of research examines the deleterious consequences of a high BLM, the authors highlight the positive work outcomes associated with a low BLM.
Novel step-down topologies of star-connected autotransformer
Authors: Wang JiaRong , He Bo , Chen XiaoQiang 
Published: September 2021

Purpose
This paper aims to obtain a symmetrical step-down topology with lower equivalent capacity and wider step-down range under the condition of the same output. Two new symmetrical step-down topologies of star-connected autotransformers are proposed in this paper. Taking the equivalent capacity as the main parameter, the obtained topologies are modeled and analyzed in detail.

Design/methodology/approach
This paper adopts the research methods of design, modeling, analysis and simulation verification. First, the star-connected autotransformer is redesigned according to the design objective of symmetrical step-down topology. In addition, the mathematical model of two topologies is established and a detailed theoretical analysis is carried out. Finally, the theoretical results are verified by simulation.

Findings
Two symmetrical star-connected autotransformer step-down topologies are designed, the winding configurations of the corresponding topology are presented, the step-down ranges of these three topologies are calculated and the influence of step-down ratio on the equivalent capacity of autotransformer are analyzed. Through analysis, the target step-down topologies are obtained when the step-down ratio is [1.1, 5.4] and [1.1, 1.9] respectively.

Research limitations/implications
Because the selected research object is only a star-connected autotransformer, the research results may lack generality. Therefore, researchers are encouraged to further study the topologies of other autotransformers.

Practical implications
This paper includes the implications of the step-down ratio on the equivalent capacity of autotransformers and the configuration of transformer windings.

Originality/value
The topologies designed in this paper enable star-connected autotransformer in the 12-pulse rectifier to be applied in step-down circumstances rather than situations of harmonic reduction only. At the same time, this paper provides a way that can be used to redesign the autotransformer in other multi-pulse rectifier systems, so that those transformers can be used in voltage regulation.

Authors: Thu Nguyen N.Q. , Trang Nguyen T.M. , Tho Nguyen Dinh 
Published: September 2021

PurposeThis study, based on self-determination theory (SDT), investigates the effect of business students' future time perspective (FTP), directly and indirectly (mediated by deep learning approaches), on quality of university life.Design/methodology/approachA sample of 547 business students in Ho Chi Minh City, Vietnam, was surveyed via a two-wave process to collect data to validate the measures and to test the hypotheses using structural equation modeling (SEM).FindingsThe results produced by SEM demonstrated that FTP had no direct effect on quality of university life and that deep learning approaches fully mediated the impact of FTP on quality of university life.Practical implicationsThe study findings provide business educators with a better understanding of the role that FTP can play for business students. Increased awareness of this issue may help nurture the FTP of business students, which in turn directs them to pursue deep learning approaches to achieve a higher level of quality of university life.Originality/valueThis study is among the first to empirically investigate the overarching role that FTP plays in both deep learning approaches and quality of university life.
The tides of agencification: literature development and future directions
Authors: Waluyo Budi 
Published: September 2021

PurposeThis review frames the state of agencification studies to explore the development and results achieved to date (Q1: what has been done?) and identify future directions (Q2: what could be done?) of the studies.Design/methodology/approachA systematic approach is carried out to summarize how agencification is adopted, variability of implementation, and its effects, from literature published in the past 48 years (1973–2020). Eligibility criteria include a combination of literature quality (number of citation) and source reputation (journal impact factor). From this, 84 articles and 9 books were included in the review.FindingsThe review finds various country-specific adoptions of agencification and some similarities and differences of agencification practice across various administrative settings. Studies on the effects of agencification is limited and offer mixed results. Meanwhile, little attempt was made to reveal how micro-processes are happening in the everyday practice of agencification. The paper outlines a set of research agenda and possible alternative approaches for future studies.Research limitations/implicationsThis review provides an avenue for scholars and practitioners to pay more attention to the “street level” of agencification. Future studies may challenge New Public Management's view of agencification by proposing new perspectives based on a direct observation.Originality/valueThis study contributes to the growing amount of agencification studies by synthesizing theoretical and empirical works across countries covering developed and developing economies in local, regional, and national levels of government.
Experiences of the Hungarian criminal jurisdiction concerning the illicit trafficking of cultural properties
Authors: Kármán Gabriella 
Published: September 2021

Purpose
The special purpose of this research was to identify the current features of illicit trade of cultural properties in Hungary and the procedures dealing with it. These offences pose a significant risk of damage to cultural property and have a strong link with organised crime. This relationship underlines the need for a criminal law approach worldwide in the field of the protection of cultural goods.

Design/methodology/approach
To explore the current situation in Hungary, an empirical research was conducted in 2018 with questionnaires designed to obtain data from the criminal records. To examine the phenomenon of “illicit trafficking”, the following types of crimes against cultural goods were selected: theft, dealing in stolen goods, robbery, budget fraud and criminal offences with protected cultural goods.

Findings
As a summary, it has to be stated that even though the number of the criminal procedure of these crimes in Hungary is low, it cannot be concluded that illicit trafficking of cultural goods in Hungary occurs only rarely. A specific characteristic of the phenomenon is high latency. To examine this phenomenon, the author has drawn up a list of indicators.

Practical implications
The aim of this project is to provide background information and materials for training programs. It is necessary to develop a more comprehensive understanding of the problem. The role of the experts is outstanding in these cases; the clear definition of their tasks and competence is very important. Information to all “actors of this scene” (from the collector to the art dealers) can contribute to the prevention too.

Originality/value
This study presents the characteristics of the criminal procedures and the difficulties of both the detection and the evidentiary process to provide educational material for training. The author would like to raise awareness about the problem and draw attention to the need for unified legal practice.
Understanding the costs of interpersonal helping and governing mechanisms: an application of transaction cost economics theory
Authors: Chou Shih Yung , Ramser Charles 
Published: September 2021

PurposeUtilizing transaction cost economics (TCE) theory as the theoretical underpinning, this article aims to describe the costs of interpersonal helping and governing mechanisms that individuals may use to alleviate helping costs.Design/methodology/approachA theoretical analysis was performed by drawing upon TCE and related research.FindingsThrough the lens of TCE, the authors propose the following: First, as the costs of helping increase, interpersonal helping shifts from being triggered by an autonomous motivation to being regulated by contextual contingencies. Second, the helper is likely to utilize reciprocity to mitigate helping costs by acquiring specific assets possessed by the recipient when asset specificity is high. Third, the helper is likely to utilize organizationally sanctioned procedures and rules to mitigate helping costs by eliminating unwanted resource consumptions when outcome uncertainty is high. Finally, the helper is likely to utilize group norms to mitigate helping costs by involving others in helping or discouraging requests for recurrent help when the frequency of helping is high.Originality/valueFrom a theoretical standpoint, this article complements previous research that focuses on the dark side of interpersonal helping. Practically, the authors offer several implications that help managers minimize the costs of helping in the organization.
How does entrepreneurial orientation and SDG orientation of CEOs evolve before and during a pandemic
Authors: Yadav Hitesha , Kar Arpan Kumar , Kashiramka Smita 
Published: September 2021

PurposeAligning business innovation with the sustainable development goals (SDGs) creates immense opportunities to solve societal challenges along with business growth and productivity. This study aims to understand the evolution of Fortune firms' strategic addressing of SDG on social media as a step towards post-pandemic recovery. Using attribution theory as a theoretical lens, the authors try to investigate how entrepreneurial orientation (EO) and SDG orientation evolve with the crisis and affect the appreciation and advocacy of the SDG-related posts.Design/methodology/approachA mixed methodology of machine learning and Social media analytics such as content analysis, sentiment analysis and space–time analysis have been used, followed by multivariate analysis to validate the findings.FindingsAn evolution in CEOs’ strategic focus surrounding SDG dimensions was found, from economic in pre-pandemic phase to social and environment during the pandemic. The SDG disclosure on social media by the Fortune CEOs seems to have an influence on their social media reputation, whereas EO has no impact on social media reputation.Research limitations/implicationsWise practice of EO in information diffusion by CEOs on social media may lead to a healthy relationship with the stakeholders and better firm performance. The SDG adoption at organisation level contributes towards a sustainable society and helps tackling the challenges faced during the pandemic.Originality/valueThis study analyses the contribution of the Fortune firms to achieve a sustainable society in a pandemic environment by strategic adoption of SDGs and effective use of digital platforms.
A methodological framework for crafting situated services
Authors: Mazzarella Francesco , May Andrew , Mitchell Val 
Published: September 2021

PurposeThis paper discusses how service design can be used to activate a transition of textile artisan communities towards a sustainable future.Design/methodology/approachTwo participatory case studies were undertaken with textile artisans in the UK and South Africa. These led to the development of an original methodological framework for “crafting situated services” – services designed to be meaningful to the local communities within which they are embedded. An evaluation study assessed the originality of the framework, its relevance for tackling real-world problems, its extensibility and the rigour of the research process.FindingsThe framework brings together a variety of roles, methods and tools that designers can adopt in order to enter communities, make sense of sustainable futures, facilitate the co-design of situated services and activate legacies within communities. Building on emerging anthropological approaches, the framework makes a bridge between service management and service design for social innovation, advancing the field towards design for social entrepreneurship.Originality/valueArguing against the idea of the designer “parachuting” into communities to create services regardless of the local context, the concept of “situated services” is proposed in this paper, alongside a process for “crafting” meaningful social innovations. This requires the service designer to adopt a more situated and embedded approach to designing with communities in order to align with their needs and aspirations, interweave places, time, people and practices within the process, and co-design contextually better services.

Authors: Chen Yu Hsin , Keng Ching-Jui , Chen Ye-Li 
Published: September 2021

PurposeWith the advancements of Internet of Things (IoT) and artificial intelligence (AI) in recent years, smart objects (SOs) have been widely applied in the lives of consumers to fulfill a variety of functions. This research aims to explore the new interaction experience between consumers and a smart speaker that can create the effect of customer engagement by enhancing the gendered voice and product smartness.Design/methodology/approachThis study conducted a 2 × 2 × 2 between-subject experiment to validate the research model and the hypotheses.FindingsThe results indicate that a high level of interaction experience between the users and smart speaker devices increases customer engagement. Smart speaker devices that present female voices have a high product smartness, whereas high levels of interaction experience are more effective in customer engagement. Furthermore, the results also show a moderate effect of gendered voice and product smartness between the interaction experience levels and customer engagement.Originality/valueThis study contributes to the assemblage theory and the interaction experience levels between users and smart speaker devices in IoT. Based on the results, suggestions on enhancing the smartness ability and application services of new smart speaker devices are proposed. The findings of this study can promote a more continuous interaction between users and smart speakers.
Experimental characterization of a novel ventilation system for multi-story buildings with continuous curtain walls
Authors: Fascetti Alessandro , Palladino Alessandro 
Published: September 2021

PurposeThe purpose of this paper is to present the results of an experimental campaign conducted on a recently developed fire protection system (FPS), specifically designed for installation on continuous glass curtain walls systems typical of multi-story buildings.Design/methodology/approachThe authors will first present the theoretical derivation of the relevant parameters to characterize and predict the fire evolution and probability of flashover, according to existing codes and standards. Then, the results of two full-scale tests will be presented in terms of temperature fields, thermal gradients and position of the neutral plane.FindingsThe experimental evidence shows how the proposed system is able to dramatically reduce internal temperatures in the rooms interested by the fire, also allowing for safer evacuation procedures by increasing the height of the neutral plane.Originality/valueThe novel window frame element comprises an automatic doubly convergent aperture system that induces ventilation in the compartment by increasing internal convection in the rooms subject to the fire. This allows for an efficient dispersion of hot gases and fumes and a drastic improvement in safety for both the occupants and firefighting operators. The theoretical results are then compared to the experimental evidence to evaluate the performance of the proposed ventilation system in the context of existing standards and design procedures.

Authors: Ding Jingda , Liu Chao , Yuan Yiqing 
Published: September 2021

PurposeThis paper aims to explore the characteristics of knowledge diffusion of library and information science to reveal its development trend and influence on other disciplines.Design/methodology/approachBased on the ESI discipline classification, this paper measures the knowledge diffusion from the library and information science to other disciplines over the last 24 years using indicators in four dimensions: breadth, intensity, speed and theme of knowledge diffusion.FindingsThe results show that the knowledge diffusion breadth of library and information science is wide, spreading to 21 ESI disciplines; the knowledge spread mainly concentrates in four soft or applied disciplines, and yet partially inter-disciplinary, and the knowledge diffusion intensity to each ESI discipline is parabolic whose highest point is mostly in 2004–2005; the speed of spreading to the 21 ESI disciplines is faster and faster, and the articles at the highest speed of knowledge diffusion are basically published after 2005; the knowledge diffusion themes are becoming increasingly diverse, deepening and specialization over time.Originality/valueThis paper modifies the relevant indicators of knowledge diffusion and constructs a measurement framework of knowledge diffusion from four aspects: breadth, intensity, speed and theme. The research method can also be used to explore the characteristics of knowledge absorption of a discipline from other ones.
