Intrinsic plasticity of cerebellar Purkinje cells in motor learning circuits
Authors: Jang Dong Cheol , Shim Hyun Geun , Kim Sang Jeong 
Published: January 2019

AbstractIntrinsic plasticity of cerebellar Purkinje cells (PCs) is recently highlighted in the cerebellar local circuits, however, its physiological impact on the cerebellar learning and memory remains elusive. Using a mouse model of memory consolidation deficiency, we found that the intrinsic plasticity of PCs may be involved in motor memory consolidation. Gain-up training of the vestibulo-ocular reflex produced a decrease in the synaptic weight of PCs in both the wild-type and knockout groups. However, intrinsic plasticity was impaired only in the knockout mice. Furthermore, the observed defects in the intrinsic plasticity of PCs led to the formation of improper neural plasticity in the vestibular nucleus (VN) neurons. Our results suggest that the synergistic modulation of intrinsic and synaptic plasticity in PCs is required for the changes in following plasticity in the VN, thereby contributes to the long-term storage of motor memory.

AbstractSafety and health of astronauts in space is one of the most important aspects of space exploration, however, the genomic research about how a weightless space can affect astronaut’s health was limited. In this study, we sequenced 25 transcriptomic, 42 metabolomic and 35 metagenomic data of 15 rhesus macaques (Macaca mulatta) spanning seven simulated weightlessness experiment stages. We identified 84 genes, 1911 features and 55 genera which are significantly changed in blood and muscle, hippocampal region, dorsomedial prefrontal cortex as well as fecal, respectively. Furthermore, performing the integrated analysis of three omics data, we found several pathways which were related to regulation of immune system process, glucose uptake, reaction to threatens, neurotoxic and bone or joints damage, such as tyrosine metabolism and tryptophan metabolism. Our results provided an initial attempt of “multi-omics” approaches which combined transcriptomics, metabolomics and metagenomics to illustrate some molecular clues for simulated weightlessness effect on the rhesus macaques and potential sight of microgravity’s effect on astronauts’ health.

Published: January 2019

ABSTRACTAimTo better understand and more realistically predict future species distribution ranges, it is critical to account for local adaptation and phenotypic plasticity in populations’ responses to climate. This is challenging because local adaptation and phenotypic plasticity are trait-dependent and traits co-vary along climatic gradients, with differential consequences for fitness. Our aim is to quantify local adaptation and phenotypic plasticity of vertical and radial growth, leaf flushing and survival across Fagus sylvatica range and to estimate each trait contribution to explain the species occurrence.LocationEuropeTime period1995 – 2014; 2070Major taxa studiedFagus sylvatica L.MethodsWe used vertical and radial growth, flushing phenology and mortality of Fagus sylvatica L. recorded in BeechCOSTe52 (>150,000 trees). Firstly, we performed linear mixed-effect models that related trait variation and co-variation to local adaptation (related to the planted populations’ climatic origin) and phenotypic plasticity (accounting for the climate of the plantation), and we made spatial predictions under current and RCP 8.5 climates. Secondly, we combined spatial trait predictions in a linear model to explain the occurrence of the species.ResultsThe contribution of plasticity to intra-specific trait variation is always higher than that of local adaptation, suggesting that the species is less sensitive to climate change than expected; different traits constrain beech’s distribution in different parts of its range: the northernmost edge is mainly delimited by flushing phenology (mostly driven by photoperiod and temperature), the southern edge by mortality (mainly driven by intolerance to drought), and the eastern edge is characterised by decreasing radial growth (mainly shaped by precipitation-related variables in our model); considering trait co-variation improved single-trait predictions.Main conclusionsPopulation responses to climate across large geographical gradients are trait-dependent, indicating that multi-trait combinations are needed to understand species’ sensitivity to climate change and its variation across distribution ranges.
The “I” in government archives: the individual as stakeholder
Authors: Peterson Trudy Huskamp 
Published: January 2019

Purpose
The purpose of this paper is to discuss the critical reasons why citizens need government archives, with an elaboration on why managing electronic records is crucial.

Design/methodology/approach
The paper offers a philosophical framework that argues that not managing records harms individuals. Examples from several countries are reviewed to find the relevance of the records relationships between people and governments, and the nexus between human rights and archives through an examination of the first three articles of the Universal Declaration of Human Rights is analyzed.

Findings
The paper identifies a strong relationship between human rights and archives and the way lives are reflected in the records in government archives. This reinforces the argument that governments need clearly established and legally empowered archival institutions.

Originality/value
Critical examination of the “I” in government archives is relatively rare in the literature, particularly when linked to the human rights implications of government records. The study is a constructive beginning for further academic discussions to explore this dimension, which in turn is related to both the efficiency of governance and the public trust in government.
Social and psychological determinants of value co-creation behavior for South Korean firms
Authors: Yoon Sungjoon , Lee Eun-Mi 
Published: January 2019

PurposeIn view of the increasing importance of creating values that require shared societal responsibilities to be borne by not just firms but customers as well, the purpose of this paper is to empirically investigate whether customers’ social capital plays a role in creating shared values for South Korean firms directly or indirectly through social identity and corporate authenticity.Design/methodology/approachTo understand the effects of social capital on value co-creation, the authors conducted a face-to-face questionnaire survey with a selected group of 400 adult respondents aged more than 20 years. To verify precision in wording and sentence structure and the validity of questions in reflecting the study objective, the authors conducted a pretest on 40 respondents before administering the main survey. Ultimately, 50 questionnaires considered inappropriate and with inconsistent response patterns were discarded, leaving 350 questionnaires for the statistical analysis.FindingsThis research adopts the consumer-centric as well as societal perspectives to conceptualize value co-creation behavior, and tests the moderating roles of psychometric measures of self-monitoring and corporate trust. Next, the research confirms whether social identity and perceived corporate authenticity mediate the relationship between social capital and value co-creation.Originality/valueThe study results shed new insights into the societal, psychological and normative aspects of value co-creation.
Extending a TAM–TTF model with perceptions toward telematics adoption
Authors: Chen Nai-Hua 
Published: January 2019

Purpose
The purpose of this paper is to examine a framework integrating the technology acceptance model (TAM), individuals’ task–technology fit (TTF) and perceptions toward adopting automobile telematics devices.

Design/methodology/approach
This study integrated the TAM with TTF to understand individual perceptions of a technology’s value. In addition, the intrinsic motivational factors toward technology usage, including positive perceptions (perceived enjoyment, personal innovation and perceived uniqueness) and negative perceptions (perceived risk and performance gap), were considered in the model. Furthermore, the moderating effect of driving experience was examined.

Findings
The perceived usefulness (PU) of telematics as well as perceived ease of use (PEOU) affected drivers’ adoption intentions. PEOU had a greater effect on adoption intentions than PU, and technology characteristics had a greater effect on TTF than task characteristics. Moreover, individuals’ perceptions of perceived enjoyment and uniqueness affected PU and PEOU. The negative perceptions of perceived risk and performance gap affected PU and PEOU, respectively. Furthermore, driving experience significantly weakened the relationship between PU and intentions.

Originality/value
Telematics is a niche market due to the development of the Internet of Things, but users’ adoption intentions remain unknown. This study constructed a more comprehensive model and tested the impacts of certain variables on telematics adoption, with driving experience as a crucial moderator.
Food insecurity amongst older people in the UK
Authors: Purdam Kingsley , Esmail Aneez , Garratt Elisabeth 
Published: January 2019

PurposeThe purpose of this paper is to present findings from research into food insecurity amongst older people aged 50 years and older in the UK.Design/methodology/approachThis paper uses secondary analysis of national-level survey data and semi-structured interviews with older people receiving emergency food from foodbanks.FindingsThere is a forgotten care gap in the UK where a substantial number of older people are living in food insecurity. Many older people live alone and in poverty, and increasing numbers are constrained in their spending on food and are skipping meals. Food insecurity amongst older people can be hidden. Within families a number of older people were trying to ensure that their children and grandchildren had enough to eat, but were reluctant to ask for help themselves.Research limitations/implicationsThe broad categorisation of older people aged 50 and above comprises people in very different circumstances. The qualitative component of the research was undertaken across various sites in a single city in England. Despite these limitations, the analysis provides important insights into the experiences of the many older people enduring food insecurity.Practical implicationsAn increased public and professional awareness of food insecurity amongst older people is needed. Increased routine screening for under-nutrition risk is a priority. Policy initiatives are needed that are multifaceted and which support older people across a range of age groups, particularly those living alone.Social implicationsFood insecurity amongst older people in the UK raises questions about the present policy approach and the responsibilities of the government.Originality/valueThe research provides important new insights into the experiences of the many older people experiencing food insecurity in the UK by drawing on survey data and interviews with older people using foodbanks.
Career chance experience of Korean women workers
Authors: Kim Namhee , Jang Suh Young , Baek Pyounggu 
Published: January 2019

Purpose
The purpose of this paper is to understand Korean women’s lived experience with career chance given the unique cultural traditions.

Design/methodology/approach
This study adopted a basic qualitative research design. The data from semi-structured person-to-person, in-depth interviews were analyzed using a constant comparative method.

Findings
The findings revealed that the participants dealt with their career chance events to maintain harmony. Their experienced chance events were scattered over a period of time, but as a whole, these events became meaningful for their career development. The lessons learned through their experiences transformed their priorities in career decisions and life values.

Research limitations/implications
This study yielded insightful theoretical and practical implications. From a theoretical perspective, this study identified the key elements of career chance events and interactions among these experiences, which can be further developed for future theory building.

Practical implications
From a practical perspective, this study sheds light on career education and counseling programs for adult women in an educational setting. In an organizational setting, this study recommends creating an employee career development culture where women employees are encouraged to take advantage of unpredicted career chance experiences.

Originality/value
This study provides culturally unique contributions to the body of literature on career chance events experienced by Korean women, which may not be adequately accounted for in most existing theories driven by western individualistic ideas of careers.
Too painful to think about: chemsex and trauma
Authors: Morris Stephen 
Published: January 2019

Purpose
Whilst chemsex is a relatively new phenomenon, trauma is not. Freud borrowed the word from physical medicine, where it was used to describe tissue damage, and applied it, for the first time, as a metaphor to a psychological process by which the protective functioning of the mind can too be pierced and wounded by events. The chemsex environment hosts a myriad of potentially traumatising scenarios and experiences, though perhaps disguised as exhilaration or excitement. The paper aims to discuss these issues.

Design/methodology/approach
The paper is a practitioner’s experience.

Findings
These experiences piled on top of childhood experiences of being “less than” for being gay, can be responsible for widespread undiagnosed post-traumatic stress disorder (PTSD) among those who engage in chemsex. This paper explores this possibility and offers solutions.

Originality/value
Compounded trauma and PTSD symptoms amongst MSM who engage in chemsex has to date, not been researched.
Spatial combined cable element for cable-supported bridges
Authors: Wei Jiandong , Guan Manyu , Cao Qi , Wang Ruibin 
Published: January 2019

Purpose
The purpose of this paper is to analyze the cable-supported bridges more efficiently by building the finite element model with the spatial combined cable element.

Design/methodology/approach
The spatial combined cable element with rigid arms and elastic segments was derived. By using the analytical solution of the elastic catenary to establish the flexibility matrix at the end of the cable segment and adding it to the flexibility matrix at the ends of the two elastic segments, the flexibility matrix at the end of the cable body is obtained. Then the stiffness matrix of the cable body is established and the end force vector of cable body is given. Using the displacement transformation relationship between the two ends of the rigid arm, the stiffness matrix of the combined cable element is derived. By assigning zero to the length of the elastic segment(s) or/and the rigid arm(s), many subdivisions of the combined cable element can be obtained, even the elastic catenary element.

Findings
The examples in this field and specially designed examples proved the correctness of the proposed spatial combined cable element.

Originality/value
The combined cable element proposed in this study can be used for the design and analysis of cable-stayed bridges. Case studies show that it is able to simulate cable accurately and could also be used to simulate the suspenders in arch bridges as well in suspension bridges.
The global carbon budget and the Paris agreement
Authors: Alcaraz Olga , Buenestado Pablo , Escribano Beatriz , Sureda Bàrbara , Turon Albert , Xercavins Josep 
Published: January 2019

Purpose
The main purpose of this paper is to introduce the concept of global carbon budget (GCB) as a key concept that should be introduced as a reference when countries formulate their mitigation contributions in the context of the Paris Agreement and in all the monitoring, reporting and verification processes that must be implemented according to the decisions of the Paris Summit.

Design/methodology/approach
A method based on carbon budget accounting is used to analyze the intended nationally determined contributions (INDCs) submitted by the 15 countries that currently head the ranking of global emissions. Moreover, these INDCs are analyzed and compared with each other. Sometimes, inadequate methodologies and a diverse level of ambition in the formulated targets are observed.

Findings
It is found that the INDCs of those 15 countries alone imply the release into the atmosphere of 84 per cent of the GCB for the period 2011-2030, and 40 per cent of the GCB available until the end of the century.

Originality/value
This is the first time the INDCs of the top 15 emitters are analyzed. It is also the first analysis made using the GCB approach. This paper suggests methodological changes in the way that the future NDCs might be formulated.

Data collected were subjected to correlation and regression analyses in pursuance of the study’s stated objective.FindingsThe results of this study found that top management support, customer data and customer information processing are positively related to organizational performance, while other variables of customer orientation, training orientation and integration of CRM have no significant influence on organizational performance.Originality/valueThe paper addresses CRM dimensions issues specifically for telecommunication companies in Kuwait.
Collaboration in reverse: a conceptual framework for reverse logistics operations
Authors: Mahadevan Kumaraguru 
Published: January 2019

PurposeThe purpose of this paper is to present the research carried out on the development of a conceptual framework termed as the reverse collaboration framework (RCF) to provide supply chain (SC) visibility and information sharing to practitioners in a reverse logistics (RL) operations.Design/methodology/approachThe research methodology used in this research is a combination of concept mapping, and the extension of the work of other researchers (deductive approach) to develop a RCF that connects tools, techniques, systems and RL processes.FindingsThis research shows that by integrating tools, systems, tools and techniques with RL processes by means of the RCF will increase performance and productivity of a RL operations. This is demonstrated by applying the RCF to a consumer electronics business that proves that the time taken for the end to end RL operations is reduced by 20%.Research limitations/implicationsThe RCF has been demonstrated with the data from a consumer electronics organisation. Literature points out that there are many different mathematical models for RL across a number of industries. Thus, at this stage, it is not clear if the RCF developed in this research will work in other industries, such as the newspaper, plastic bottles and online retailers industry where product returns are high. This research work can be extended in developing an IT solution by future researchers that can be linked to the main ERP system of an organisation.Practical implicationsSC managers can use the RCF in the extended form of an IT solution to manage the RL operations of their organisations.Originality/valueThere is a lack of research in the space of reverse collaboration in the broader field of SC management. This paper has fulfilled that gap.
Cloud-based sustainable management of electrical and electronic equipment from production to end-of-life
Authors: Conti Massimo , Orcioni Simone 
Published: January 2019

Purpose
The purpose of this paper is to describe a system and a database structure for the tracing of the waste of electric and electronic equipment (WEEE) using radio-frequency identification tags.

Design/methodology/approach
The problems related to the management of WEEE and the international directives have been presented and analyzed. The authors propose a traceability system to extend the tracing in the reverse logistics.

Findings
The proposed systems allow a more efficient management of the reuse, repair and recycle phase of the products and components, thus reducing the disposal of the electric and electronic equipment. There are many possible positive impacts of the system. The authors investigate, in particular, the impact of the single component tracing on the disposal cost reduction and on the reliability improvement using reused components.

Research limitations/implications
The system has been tested in the production chain of a company that produces electronic equipment for elevators. Up to now, the results and impact are limited to the company.

Practical implications
The system has been applied in the management of reused components of a specific company. The immediate result was that the system allowed the redesign of the electronic product with a cost reduction and reliability improvement.

Social implications
The authors think that the proposed solution allows a step forward in the reduction of WEEE.

Originality/value
The database structure and the web application, used to track the entire working life of an electronic appliance, are original. Original is also the idea of tracing all the single components of the electronic products.
From humanitarianism to family building
Authors: Onayemi Olayinka Modupe 
Published: January 2019

Purpose
Adoption practice is originally designed as a live-saving option for some category of children. In recent times, this purpose has been challenged by several social, biological and cultural exigencies. Hence, a notable morphing of the practice to satisfying adopters’ need has been observed, however, requiring further interrogations. The paper aims to discuss these issues.

Design/methodology/approach
Data were collected through sessions of interviews with six adoption officials (social workers), four orphanage managers, three legal practitioners and 13 prospective and successful adopters, across three selected states.

Findings
The study records contemporary adoption practices as mostly a management strategy for infertility by bringing to fore diverse narratives that reveal adoption as now primarily construed, subconsciously implemented and ultimately serving in many ways as the social security mechanism for adopters than for securing the children who are to be adopted.

Social implications
This by implication results in poor adoptive parent–child bonding, disservice and maltreatments in diverse ways.

Originality/value
This study heralds the “rebranded” security benefits of adoption and enlarges the scope and genres of social security implications of child adoption in the contemporary Nigerian society.
