Individuals with Parkinson’s Disease Retain Spatiotemporal Gait Control With Music and Metronome Cues
Authors: Chawla Guneet , Wygand Madelon , Browner Nina , Lewek Michael D 
Published: July 2019

AbstractBackgroundParkinson’s disease (PD) is marked by a loss of motor automaticity, resulting in decreased control of step length during gait. Rhythmic auditory cues (metronomes or music) may enhance automaticity by adjusting cadence. Both metronomes and music may offer distinct advantages, but prior attempts at quantifying their influence on spatiotemporal aspects of gait have been confounded by altered gait speeds from overground walking. We hypothesized that when gait speed is fixed, individuals with PD would experience difficulty in modifying cadence due to the concomitant requirement to alter step length, with greater changes noted with metronomes compared to music cues.Research QuestionCan a metronome or music promote spatiotemporal adjustments when decoupled from changes in gait speed in individuals with PD?Methods21 participants with PD were instructed to time their steps to a metronome and music cues (at 85%, 100%, and 115% of overground cadence) during treadmill walking. We calculated cadence, cadence accuracy, and step length during each cue condition and an uncued control condition. We compared the various cue frequencies and auditory modalities.ResultsAt fixed gait speeds, participants were able to increase and decrease cadence in response to auditory cues. Music and metronome cues produced comparable results in cadence manipulation with greater cadence errors noted at slower intended frequencies. Nevertheless, the induced cadence changes created a concomitant alteration in step length, with music and metronomes producing comparable changes. Notably, longer step lengths were induced with both music and metronome during slow frequency cueing.SignificanceThis important change conflicts with conventional prescriptive approaches, which advocate for faster cue frequencies, if applied on a treadmill. The music and metronome cues produced comparable changes to gait, suggesting that either cue may be effective at overcoming the shortened step lengths during treadmill walking if slower frequencies are used.
OHNOLOGS v2: A comprehensive resource for the genes retained from whole genome duplication in vertebrates
Authors: Singh Param Priya , Isambert Hervé 
Published: July 2019

ABSTRACTAll vertebrates including human have evolved from an ancestor that underwent two rounds of whole genome duplication (2R-WGD). In addition, teleost fish underwent an additional third round of genome duplication (3R-WGD). The genes retained from these genome duplications, so-called ohnologs, have been instrumental in the evolution of vertebrate complexity, developmental patterns and susceptibility to genetic diseases. However, the identification of vertebrate ohnologs has been challenging, due to lineage specific genome rearrangements since 2R- and 3R-WGD. We have previously identified vertebrate ohnologs using a novel synteny comparison across multiple genomes. Here, we refine and apply this approach on 27 vertebrate genomes to identify ohnologs from both 2R- and 3R-WGD, while taking into account the phylogenetically biased sampling of available species. We assemble vertebrate ohnolog pairs and families in an expanded OHNOLOGS v2 database, which also includes non-protein coding RNA genes. We find that teleost fish have retained most 2R-WGD ohnologs common to amniotes, which have also retained significantly more ohnologs from 3R-WGD, whereas a higher rate of 2R-WGD ohnolog loss is observed in sauropsids compared to mammals and fish. OHNOLOGS v2 should allow deeper evolutionary genomic analysis of the impact of WGD on vertebrates and can be freely accessed at http://ohnologs.curie.fr.
Sex differences in innate and adaptive neural oscillatory patterns predict resilience and susceptibility to chronic stress in rats
Authors: Thériault Rachel-Karson , Manduca Joshua D. , Perreault Melissa L. 
Published: July 2019

AbstractMajor Depressive Disorder (MDD) is a chronic illness with higher incidence in women. Dysregulated neural oscillatory activity is an emerging mechanism underlying MDD, however whether sex differences in these rhythms contribute to the development of MDD symptoms is unknown. Using the chronic unpredictable stress model, we found that stress-resilient and susceptible animals exhibited sex-specific oscillatory markers in the prefrontal cortex, cingulate cortex, nucleus accumbens and hippocampus. Resilient females were predominantly characterized by increased hippocampal theta power and coherence, while resilient males exhibited increased system-wide gamma coherence. In susceptible animals, the females displayed a widespread increase in delta and reduced theta power, however males showed few within-sex differences that could delineate stress susceptibility from resilience. Finally, stress responses were mediated by the temporal recruitment of specific neural pathways, culminating in system-wide changes that correlated with the expression of depression-like behaviours. These findings show that neurophysiological responses can serve as predictive markers of behaviours linked to depression in a sex-specific manner.

Laser deposited high temperature thin film sensors for gas turbines
Authors: Yang Dongfang , Pankov Vladimir , Zhao Linruo , Patnaik Prakash 
Published: July 2019

PurposeAccurate measurements of the temperature distributions in hot section components are indispensable for the prognostic and health management of gas turbines. Thin film thermocouple (TFTC) sensors, directly fabricated on the surface of a component, add negligible mass and create little or no disturbance to airflow, and therefore, can provide accurate measurements of fast temperature fluctuations of gas turbines. The purpose of this paper is to evaluate TFTC sensors fabricated by combining pulsed laser deposition (PLD) and micromachining techniques (LM).Design/methodology/approachThe “dry” PLD/LM fabrication approach allows for excellent control of the chemical composition and physical characteristics of the constituent layers and their interfaces, thus achieving good adhesion of the layers to the substrate.FindingsThe results of thermal cyclic durability testing of the fabricated TFTC sensors demonstrated that the proposed PLD-based approach can be used to fabricate sensors that are fully functional at temperatures up to 750°C. Analyses of the sensor performance during durability testing revealed: the existence of a threshold temperature below which accurate temperature measurements were achieved; an abrupt drop in the sensor output occurring when the sensor temperature exceeded the threshold value, with a fast recovery of the sensor output once the temperature was reduced below the threshold level; and sensor “training” capable of increasing the threshold value of the TFTC through its exposure to above-the-threshold temperatures.Originality/valueThe work is the first time to demonstrate that simple PLD and LM processes can be used to fabricate TFTC that are fully functional at temperatures up to 750°C.

Published: July 2019

PurposeEthnic food is a pivotal polysemic artifact, yet commonly studied based on experience. This leaves an eclipse in understanding its overall significance and implications. The purpose of this paper is to explore the interactions of experience, intimacy and embodiment from the lens of alternative tourism and Asia as a destination image.Design/methodology/approachThe authors conducted four focus group that include Asians who take experiential learning trips and spiritual journeys across Asia-Pacific.FindingsAlternative tourists promote the growth of ethnic foodies who value impact which they determine as quality food-scape, longitudinal caring interactions with and the constant assurance of consuming food which are safe and healthy to their physical, emotional and spiritual well-being.Research limitations/implicationsAlthough our research does not employ any quantitative technique and devoid of inferential analysis, the rich qualitative data offer insights for further work that benefit ethnic food industry.Practical implicationsIndustry and policy makers are encouraged to generate contextual solutions for management of the ethnic food industry. Ethnic food consumption may flourish if the industry leads its growth through a post-modernist approach.Social implicationsA broad perspective in growing the frontiers of ethnic food tourism beyond the landscape of an economic or consumerism-dominated approach would benefit the cross-mobility of quality talents and skills as this fosters cross-cultural literacy.Originality/valueThe authors develop the Ethnic Foodies Perspective-Ethnic Food Destination Image Matrix as a pathway to further motivate knowledge cross-fertilization in ethnic food tourism studies and leverage on the transdisciplinary science, innovation, socio- and sensuous geographic arena. A constellation of ethnic food innovation should link the economic side of exotic differentiation and heritage with food processing, safety and traceability.
Community leadership and the Triple Helix model as determinants of the constitution of science parks
Authors: Bencke Fernando Fantoni , Dorion Eric Charles Henri , Prodanov Cleber Cristiano , Olea Pelayo Munhoz 
Published: July 2019

Purpose
The purpose of this paper is to analyze and understand the condition that lead to a constitution’s path of Brazilian Science Parks, in the State of Rio Grande do Sul, and consequently to propose a new dimension of analysis to the Triple Helix.

Design/methodology/approach
A qualitative approach was used to elaborate a descriptive and exploratory research design, where a case study method was applied on six science parks.

Findings
The use of the Triple Helix model could not explain the Brazilian Science Park development realities. A new element, related to the innovation model, was considered as a determinant in the constitution of the Brazilian parks, and is represented as the community leadership category, as the Fourth Helix.

Research limitations/implications
Since it is a qualitative study, the results obtained have a strong relation with the local, cultural and historically constructed contexts. Bias from the researchers’ subjectivity in the data collection procedures is present, although the validity and reliability measures were performed.

Practical implications
The construction of designed and implemented specific “fertile models,” which are capable of developing the necessary conditions for the constitution and the consolidation of science parks in Brazil.

Social implications
Such empirical contribution comes from data referring to spontaneous and endogenous local community development movements.

Originality/value
The identification of a new element of the Triple Helix innovation model is represented as the community leadership category and is considered as a key determinant in the constitution of the Brazilian Science Parks.
Potentials of top management team career development and corporate social responsibility
Authors: Hu Yelin , Zhang Qiwang , Wang Xin 
Published: July 2019

PurposeThe purpose of this paper is to explore the relationship between potentials of top management teams’ (TMT) career development and corporate social responsibility (CSR) by examining listed manufacturing companies in China. More importantly, it tried to contribute to the understanding of the senior executive’s career development in the trend of upgrading the manufacturing industry.Design/methodology/approachThe sample firms in this paper were selected from the China A-listed companies in the manufacturing industry. It collected CSR and TMT data from the Rankins CSR Ratings (RKS) Database and CSMAR database and applied the multiple regression to test the hypotheses. Moreover, it implemented the robustness test by using the standard regression method and the structural equation model.FindingsThe findings indicate that a firm’s CSR performance is significantly associated with TMT’s educational level and overseas background. The government background, academic background and financial background of high-level managers, instead, have a negative relationship with CSR performance. In addition, firm’s ownership moderates the relationship between TMT and CSR initiatives – the career development potential of TMT has different effects on promoting CSR in the context of different ownership. These relationships remain significant when the managers’ tenure, gender, age, wage and firm size are controlled.Research limitations/implicationsThe empirical research on the potentials of executive career development and CSR is limited to linear assumptions. Since there are fewer overseas holding companies in Chinese state-owned and private enterprises, it failed to reflect international differences.Practical implicationsFirst, CSR is related to the potentials of TMT career development and also the potentials of TMT career development are associated with the structure of the TMT. Second, to improve CSR, it is necessary to distinguish the different ownership of companies and then adjust the TMT structure correspondingly. Last, senior executives should choose their career direction according to their own distinct and inherent career development potentials.Originality/valueThis study explores the relationship between potentials of TMT career development and CSR. It not only expands the research in the field of CSR but also enriches the research on the career development of top executives.
Collective efforts of people to reduce disasters in the Indian Sundarban islands
Authors: Bera Mohan Kumar 
Published: July 2019

PurposePeople from chronic flood-affected areas in the Sundarban islands understand that individual efforts are not sufficient to deal with the floods of increasing magnitude caused by tidal waves in coastal areas and take proactive measures to minimise the impact of floods before turning to the government for support. Their perception of disaster risk influences them to engage in collective activities and develop strategies to mitigate flood disasters. However, many villagers do not participate in collective disaster management activities. The purpose of this paper is to explore the factors of homogeneity that motivate people to work together to reduce the impact of natural hazards.Design/methodology/approachQualitative research has been conducted in Sibpur and Gobordhanpur villages of Indian Sundarban islands. Participant observation and in-depth interview have been applied to explore the collective activities of disaster reduction. Affected, non-affected villagers, representatives of the local government and government administrative officers have been interviewed to understand the disaster management efforts of the government and local people.FindingsThe research has found that drivers of homogeneity and leadership are important for collective activities in disaster management. Threat of disasters, potential loss of livelihood and damages of properties, emotional attachment with the village and ties with extended family members influence villagers to engage in collective activity. Collective activities of villagers help to address the local needs of disaster reduction to the government in a better way.Originality/valueThe study has revealed that strong leadership is required in effective collective activities to manage disaster in the Indian Sundarban islands.
Reimagining local studies in Devon
Authors: Maxted Ian 
Published: July 2019

Purpose
The purpose of this paper is to examine the effect that government austerity policies has had on local studies in Devon and suggest a possible alternative means of maintaining local studies’ collections.

Design/methodology/approach
This paper presents an historical survey of local studies provision in the county since the nineteenth century and outlines the present local studies’ landscape.

Findings
The findings show that local studies’ provision has been severely affected by eight years of progressive cuts to public library funding and that present publications, both printed and digital, are no longer being adequately recorded.

Practical implications
This paper suggests that in Devon, the museum sector may be a more appropriate home for local studies’ library provision than are archive services.

Social implications
Volunteers in libraries, museums and archives across Devon will be involved in maintaining a union catalogue and a bibliography of local publications.

Originality/value
While this is a suggested solution for Devon, it may not be applicable in regions with different traditions of heritage provision.
Roles of cataloguing librarians in the digital era
Authors: Al Hijji Khalfan Zahran , Al-Busaidi Mohammad Khamis 
Published: July 2019

Purpose
This study aims to explore the roles and skills of Omani academic cataloguing librarians in facilitating access to various kinds of traditional and digital information resources and challenges confronting them in fulfilling that task.

Design/methodology/approach
Data for this research were gathered from 37 academic libraries in the country through a questionnaire sent to their cataloguing librarians. Google Docs format was used for cumulating and presenting quantitative data, whilst content analysis was utilized for gathering the qualitative data in specific themes according to the research questions.

Findings
The obvious findings are that Omani academic cataloguers still perform the traditional cataloguing functions, including copy and original cataloguing, and maintain authority files. Moreover, more than half of the respondents have the skills required for working in groups and are familiar with cataloguing tools such as RDA rules and BIBFRAME. However, cataloguers lack familiarity with computer languages (XML, PMH, OAI, RDF) and metadata.

Practical implications
The research concludes with suggestions to libraries for improving librarians’ skills and performance through such as provision of proficient training and establishment of a collaborative body.

Originality/value
This research addresses an area of interest to most librarians. However, few researchers in the authors’ region have focused on this topic. The study, therefore, aims to contribute to filling this gap through assessing whether cataloguers in Oman have the skills and roles required for organizing various information resources in the digital era.
Replacing a delisted brand with premium and standard private labels
Authors: Lessassy Léopold 
Published: July 2019

Purpose
The purpose of this paper is to examine the moderating effect of brand preference and type of shopping trip on the relationship between replacing a delisted national brand (NB) with a retailer’s private label (PL) brand (premium vs standard) and private label switching (PLS), that is switching from NB to PL.

Design/methodology/approach
Inside a major French retail chain store, an experiment with 1,392 NB buyers tested the impact of replacing NB with PL on PLS.

Findings
Results stress the positive contribution of PL replacements after NB delisting on buyers’ switching behaviour at different brand preference levels and shopping trip types. A main-choice NB for a major trip shopping benefits a PLS to premium PL. However, when a fill-in shopper looks for a secondary brand, competition between PL standard and NB may not be as weak as suggested in earlier studies.

Research limitations/implications
The limitation of this study is that respondents reported their purchases instead of actually buying.

Practical implications
This study highlights that the retailers that delist some NB brands in the category should adopt a strategy either to develop premium or standard PLs, depending on consumers’ brand preference and shopping trip type.

Social implications
Delisting is an opportunity to question the NB product competitiveness towards PL.

Originality/value
The study is based on actual delisting and replacement, combined with a large sample, unlike previous studies. Moreover, it bridges two important areas of research: conflict in marketing channels and PL introduction in retailers’ assortment decisions.
