Are data repositories fettered? A survey of current practices, challenges and future technologies
Authors: Khan Nushrat , Thelwall Mike , Kousha Kayvan 
Published: August 2021

PurposeThe purpose of this study is to explore current practices, challenges and technological needs of different data repositories.Design/methodology/approachAn online survey was designed for data repository managers, and contact information from the re3data, a data repository registry, was collected to disseminate the survey.FindingsIn total, 189 responses were received, including 47% discipline specific and 34% institutional data repositories. A total of 71% of the repositories reporting their software used bespoke technical frameworks, with DSpace, EPrint and Dataverse being commonly used by institutional repositories. Of repository managers, 32% reported tracking secondary data reuse while 50% would like to. Among data reuse metrics, citation counts were considered extremely important by the majority, followed by links to the data from other websites and download counts. Despite their perceived usefulness, repository managers struggle to track dataset citations. Most repository managers support dataset and metadata quality checks via librarians, subject specialists or information professionals. A lack of engagement from users and a lack of human resources are the top two challenges, and outreach is the most common motivator mentioned by repositories across all groups. Ensuring findable, accessible, interoperable and reusable (FAIR) data (49%), providing user support for research (36%) and developing best practices (29%) are the top three priorities for repository managers. The main recommendations for future repository systems are as follows: integration and interoperability between data and systems (30%), better research data management (RDM) tools (19%), tools that allow computation without downloading datasets (16%) and automated systems (16%).Originality/valueThis study identifies the current challenges and needs for improving data repository functionalities and user experiences.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-04-2021-0204
Advancing empowerment research in management control: the effects of access to information and deadlines
Authors: Bicudo de Castro Vincent , Sridharan VG 
Published: August 2021

PurposeThis paper aims to capture the effects of access to information and deadlines on empowerment and subordinate managers’ effectiveness. The purpose is to contribute to the growing empowerment-related discourse within the management control discipline.Design/methodology/approachTo test the hypotheses derived from empowerment theory, this paper collects survey data from 103 middle-level managers. Using a path model that describes all the potential theoretical relations, this study tests the survey data using a boot-strapped linear regression approach.FindingsThis study finds evidence for both direct and indirect positive effects between access to information and subordinate managers’ performance, which supports the view that empowerment has a partial mediating effect on performance. The study also finds that though the effect of access to information on empowerment is not moderated by the specification of deadlines, empowerment is negatively affected when priorities change with new deadlines.Originality/valueThis study offers two new insights as follows: First, in addressing the concern relating to the lack of clarity in the extant literature on the role of empowerment, this study finds that empowerment partially mediates the relation between access to information and performance. Second, the study finds that time-based performance targetsper sedo not affect empowerment as much as the task uncertainty, which arises with frequent changes to such a target.
The effect of change readiness of economies on international M&A flows
Authors: Moeini Gharagozloo M. Mahdi , Chen Chen , Sabz Ali Pour Farinaz 
Published: August 2021

PurposeThe purpose of this paper is to examine how a country’s change readiness impacts international mergers and acquisitions (M&A) capital flows on a national level toward host countries. The authors unpack the construct of change readiness and identify how its different dimensions impact international M&As (IMA). The authors provide a theoretical framework based on the resource-based view to facilitate an understanding of this concept.Design/methodology/approachThe authors used a fixed-effect analysis to study a sample of 2,970 IMAs announced by publicly traded US companies during 2013–2017.FindingsThe authors propose that higher levels of change readiness would help foreign firms to cope with risks and uncertainties generated by the changes and shocks in the environment of a host country. The authors find support for their hypotheses showing that higher levels of change readiness increase the number of IMAs that a country receives every year. This characteristic of the host country shows a significant influence, especially in technology-intensive IMA flows.Practical implicationsThis study provides implications for business executives and policymakers both in terms of risk mitigation strategies and investment attraction. Understanding the fact that when it comes to foreign investment in the form of IMAs business executives are aware of the importance of change readiness in host countries might lead to motivate the governments and host country officials to provide better infrastructure to boost the change readiness in their economy.Originality/valueOverall, this study improves our knowledge about mechanisms through which change readiness of host countries might impact firms' strategies for international expansion. As we are indeed living in the era of global disruptions and strong shocks caused by political turmoil, climate change and the spread of new diseases, this study contributes to the literature on risk mitigation in international business and is one of the first to look closely at the role of host countries' change readiness and the effect it might have on attracting international M&As.

Authors: Wu Lifang , Liu Zechao , Guan Yupeng , Cui Kejian , Jian Meng , Qin Yuanyuan , Li Yandong , Yang Feng , Yang Tianqin 
Published: August 2021

Purpose
This paper aims to address the problem of uncertain product quality in digital light processing (DLP) three-dimensional (3D) printing, a scheme is proposed to qualitatively estimate whether a layer is printed with the qualified quality or not cured .

Design/methodology/approach
A thermochromic pigment whose color fades at 45°C is prepared as the indicator and it is mixed with the resin. A visual surveillance framework is proposed to monitor the visual variation in a period of the entire curing process. The exposure region is divided into 30 × 30 sub-regions; gray-level variation curves (curing curves) in all sub-regions are classified as normal or abnormal and a corresponding printing control strategy is designed to improve the percentage of qualified printed objects.

Findings
The temperature variation caused by the releasing reaction heat on the exposure surface is consistent in different regions under the homogenized light intensity. The temperature in depth begins to rise at different times. The temperature in the regions near the light source rises earlier, and that far from the light source rises later. Thus, the color of resin mixed with the thermochromic pigment fades gradually over a period of the entire solidification process. The color variation in the regions with defects of bubbles, insufficient material filling, etc., is much different from that in the normal curing regions.

Originality/value
A temperature-sensitive organic chromatic chemical pigment is prepared to present the visual variation over a period of the entire curing process. A novel 3D printing scheme with visual surveillance is proposed to monitor the layer-wise curing quality and to timely stop the possible unqualified printing resulted from bubbles, insufficient material filling, etc.

Authors: Fé-Perdomo Iván La , Ramos-Grez Jorge Andres , Beruvides Gerardo , Mujica Rafael Alberto 
Published: August 2021

PurposeThe purpose of this paper is to outline some key aspects such as material systems used, phenomenological and statistical process modeling, techniques applied to monitor the process and optimization approaches reported. All these need to be taken into account for the ongoing development of the SLM technique, particularly in health care applications. The outcomes from this review allow not only to summarize the main features of the process but also to collect a considerable amount of investigation effort so far achieved by the researcher community.Design/methodology/approachThis paper reviews four significant areas of the selective laser melting (SLM) process of metallic systems within the scope of medical devices as follows: established and novel materials used, process modeling, process tracking and quality evaluation, and finally, the attempts for optimizing some process features such as surface roughness, porosity and mechanical properties. All the consulted literature has been highly detailed and discussed to understand the current and existing research gaps.FindingsWith this review, there is a prevailing need for further investigation on copper alloys, particularly when conformal cooling, antibacterial and antiviral properties are sought after. Moreover, artificial intelligence techniques for modeling and optimizing the SLM process parameters are still at a poor application level in this field. Furthermore, plenty of research work needs to be done to improve the existent online monitoring techniques.Research limitations/implicationsThis review is limited only to the materials, models, monitoring methods, and optimization approaches reported on the SLM process for metallic systems, particularly those found in the health care arena.Practical implicationsSLM is a widely used metal additive manufacturing process due to the possibility of elaborating complex and customized tridimensional parts or components. It is corroborated that SLM produces minimal amounts of waste and enables optimal designs that allow considerable environmental advantages and promotes sustainability.Social implicationsThe key perspectives about the applications of novel materials in the field of medicine are proposed.Originality/valueThe investigations about SLM contain an increasing amount of knowledge, motivated by the growing interest of the scientific community in this relatively young manufacturing process. This study can be seen as a compilation of relevant researches and findings in the field of the metal printing process.
Workplace spirituality, self-compassion and mindfulness as antecedents of employee mental wellbeing
Authors: K Jnaneswar , Sulphey M.M. 
Published: August 2021

PurposeMental wellbeing brings in multiple benefits to employees and their organizations like better decision-making capacity, greater productivity, resilience and so on. The purpose of this paper is to examine the relationship of a few antecedents of mental wellbeing like workplace spirituality, mindfulness and self-compassion, using structural equation modeling (SEM).Design/methodology/approachUsing the convenience sampling method, data were collected from 333 employees of various organizations in India and SEM was performed using the R Program to test the hypotheses.FindingsResults suggest that mindfulness and self-compassion influenced the mental wellbeing of employees. It was also observed that workplace spirituality has a significant influence on both mindfulness and self-compassion.Originality/valueAn in-depth review of the literature revealed that no previous studies had examined the complex relationship between workplace spirituality, mindfulness, self-compassion and the mental wellbeing of employees. This research suggests that workplace spirituality, mindfulness and self-compassion are important factors that influence employees' mental wellbeing, and it empirically tests this in a developing country context. The present study enriches the literature studies on mental wellbeing, mindfulness, self-compassion and workplace spirituality by integrating “mindfulness to meaning theory”, “socio-emotional selectivity theory”, and “broaden and build theory”.
Pharmaceutical supply chains and management innovation?
Authors: Papalexi Marina , Bamford David , Nikitas Alexandros , Breen Liz , Tipi Nicoleta 
Published: August 2021

Purpose
This paper aims to evaluate the implementation of innovative programmes within the downstream domain of the pharmaceutical supply chain (PSC), with the aim of informing improved service provision.

Design/methodology/approach
A mixed-method approach was used to assess to what extent innovation could be adopted by hospital and community pharmacies to improve the delivery process of pharmaceutical products. Unstructured interviews and 130 questionnaires were collected and analysed to identify factors that facilitate or prevent innovation within PSC processes.

Findings
The analysis led to the creation of the innovative pharmaceutical supply chain framework (IPSCF) that provides guidance to health-care organisations about how supply chain management problems could be addressed by implementing innovative approaches. The results also indicated that the implementation of Lean and Reverse Logistics (RL) practices, supported by integrated information technology systems, can help health-care organisations to enhance their delivery in terms of quality (products and service quality), visibility (knowledge and information sharing), speed (response to customers and suppliers needs) and cost (minimisation of cost and waste).

Practical implications
The study’s recommendations have potential implications for supply chain theory and practice, particularly for pharmacies in terms of innovation adoption. The IPSCF provides guidance to pharmacies and health-care organisations to develop more efficient and effective supply chain strategies.

Originality/value
This research contributes to the academic literature as it adds novel theoretical insights to highly complex delivery process innovation.
Chineseness and behavioural complexity: rethinking Chinese tourist gaze studies
Authors: Li Mohan , Tucker Hazel , Chen Ganghua 
Published: August 2021

Purpose
This study aims to reconsider Chinese tourist gaze studies, examining the extent to which extant studies and theoretical models relating to the Chinese tourist gaze have overcome the Eurocentric limits of John Urry’s concept of the tourist gaze and elaborated the complexity of Chinese tourists’ gazes and visual practices.

Design/methodology/approach
Content analysis is carried out, examining research articles, books, book chapters and PhD and MSc theses collected from multiple English and Chinese databases.

Findings
The research results manifest that, overall, the previous studies, mobilise cultural essentialism, with an overestimation of the “Chineseness” of Chinese tourists’ behavioural patterns, which are widely believed to be framed by, but also constituting of, unique Chinese culture. Overdependence on Chinese cultural values and traditional philosophies as sources for rationale has resulted in a handful of theoretical frameworks, which appear to be of insufficient magnitude both in terms of their contribution to the original tourist gaze model and in their manifesting of the complexity of Chinese tourists’ visual behaviour. Indeed the divide that once deliberately set apart West and East, or more precisely Western and Chinese tourist gazes, seems to become accentuated in most attempts to study and write about Chinese tourist gaze(s). The previous studies thus largely serve to mirror the Eurocentrism of Urry’s gaze, rather than challenging it.

Research limitations/implications
This study has a few limitations, especially, as this study only reviews and analyses the studies of the Chinese tourist gaze. It means that the conclusion might not well be generalised to either the investigation of the tourist gaze in another culture or the Chinese tourist studies, at large, which might exhibit a different pattern deserving more academic attention in future. Moreover, the authors recommend the future researchers, who are eager to probe Chinese tourists’ behavioural pattern, to seek for new pathways and alternative paradigms, which would be useful in overcoming the limits of cultural representations and in reducing the problematic Sino-Western divide.

Originality/value
Despite not aiming to reconceptualise the Chinese tourist gaze, this review paper contributes to the field of tourist gaze studies by engaging critically with the bias and theoretical insufficiencies that have emerged, while this concept is appropriated and re-formulated to explain Chinese tourists’ gazes and visual practices. On this basis, the authors suggest a critical redirection of the extant Chinese tourist gaze studies, which would be rather significant to those researchers in future with an interest to research what the Chinese tourists prefer to see in travel and how they engage with the gazee.
The impact of contextual information on decision‐making in footwear examination: An eye‐tracking study
Authors: Yu Yang , Luo Yaping , Huang Lu , Quan Yongzhi 
Published: August 2021

AbstractIn order to investigate whether context factors and expectations might potentially influence the decision‐making of forensic footwear examiners, we collected the gaze process of experts examining the shoeprint image sets through the eye‐tracking recorder. Additional to eye movement data as an objective measure, questionnaires were completed, and survey was conducted afterwards. Twenty‐three qualified examiners assessed the similarity among shoe images for 22 different cases, including three sets were laterally reversed. We divided the experiment into two sessions, and then compared the examiners’ performance with and without contextual information. The results showed the effects of contextual bias manipulate on both behavioral data and eye tracking data. The consensus and accuracy of examiners with contextual information were higher than those without contextual information. In the eye‐tracking data, there is a significant difference between fixation counts and saccadic counts under contextual information. In addition, we found that the contextual information produced significant changes in inter‐examiner consistency as measured by the Earth Mover Distance metric. However, there is no significant statistic differences in saccadic amplitude and total fixation duration of the examiners after exposure to contextual information. Our research results are instructive for understanding the cognitive process of shoeprint examination involved in real cases. In this process, stimuli related to context factors may affect decision‐making and behavior. Implications for contextual effect causes are discussed.
The uneven distribution of futurity: Slow emergencies and the event of COVID‐19
Authors: Grove Kevin , Rickards Lauren , Anderson Ben , Kearnes Matthew 
Published: August 2021

AbstractThe ongoing COVID‐19 pandemic strains conventional temporal imaginaries through which emergencies are typically understood and governed. Rather than a transparent and linear temporality, a smooth transition across the series event/disruption–response–post‐event recovery, the pandemic moves in fits and starts, blurring the boundary between normalcy and emergency. This distended temporality brings into sharp relief other slow emergencies such as racism, poverty, biodiversity loss, and climate change, which inflect how the pandemic is known and governed as an emergency. In this article, we reflect on COVID‐19 responses in two settler colonial societies—Australia and the United States—to consider how distinct styles of pandemic responses in each context resonate and dissonate across the racially uneven distribution of futurity that structures liberal order. In each case, the event of COVID‐19 has indeed opened a window that reveals multiple slow emergencies; yet in these and other responses this revelation is not leading to meaningful changes to address underlying forms of structural violence. In Australia and the United States, we see how specific slow emergencies—human‐induced climate change and anti‐Black violence in White supremacist societies, respectively—become intensified as liberal order recalibrates itself in response to the event of COVID‐19.
Epigenetic age prediction
Authors: Simpson Daniel J. , Chandra Tamir 
Published: August 2021

AbstractAdvanced age is the main common risk factor for cancer, cardiovascular disease and neurodegeneration. Yet, more is known about the molecular basis of any of these groups of diseases than the changes that accompany ageing itself. Progress in molecular ageing research was slow because the tools predicting whether someone aged slowly or fast (biological age) were unreliable. To understand ageing as a risk factor for disease and to develop interventions, the molecular ageing field needed a quantitative measure; a clock for biological age. Over the past decade, a number of age predictors utilising DNA methylation have been developed, referred to as epigenetic clocks. While they appear to estimate biological age, it remains unclear whether the methylation changes used to train the clocks are a reflection of other underlying cellular or molecular processes, or whether methylation itself is involved in the ageing process. The precise aspects of ageing that the epigenetic clocks capture remain hidden and seem to vary between predictors. Nonetheless, the use of epigenetic clocks has opened the door towards studying biological ageing quantitatively, and new clocks and applications, such as forensics, appear frequently. In this review, we will discuss the range of epigenetic clocks available, their strengths and weaknesses, and their applicability to various scientific queries.

AbstractSenescent astrocytes accumulate with aging and contribute to brain dysfunction and diseases such as Alzheimer's disease (AD), however, the mechanisms underlying the senescence of astrocytes during aging remain unclear. In the present study, we found that Yes‐associated Protein (YAP) was downregulated and inactivated in hippocampal astrocytes of aging mice and AD model mice, as well as in D‐galactose and paraquat‐induced senescent astrocytes, in a Hippo pathway‐dependent manner. Conditional knockout of YAP in astrocytes significantly promoted premature senescence of astrocytes, including reduction of cell proliferation, hypertrophic morphology, increase in senescence‐associated β‐galactosidase activity, and upregulation of several senescence‐associated genes such as p16, p53 and NF‐κB, and downregulation of Lamin B1. Further exploration of the underlying mechanism revealed that the expression of cyclin‐dependent kinase 6 (CDK6) was decreased in YAP knockout astrocytes in vivo and in vitro, and ectopic overexpression of CDK6 partially rescued YAP knockout‐induced senescence of astrocytes. Finally, activation of YAP signaling by XMU‐MP‐1 (an inhibitor of Hippo kinase MST1/2) partially rescued the senescence of astrocytes and improved the cognitive function of AD model mice and aging mice. Taken together, our studies identified unrecognized functions of YAP‐CDK6 pathway in preventing astrocytic senescence in vitro and in vivo, which may provide further insights and new targets for delaying brain aging and aging‐related neurodegenerative diseases such as AD.
