The antecedents and consequences of value co-creation behaviors in a hotel setting: a two-country study
Get PDFThis study examines the antecedents and consequences of value co-creation behavior in a hospitality context. An online questionnaire with samples of hotel patrons in the United States and Australia was used to obtain data and partial least square modeling was used in the analysis. The results suggest patron fairness perception enhances trust and identification with a hotel, which encourage engagement in the value co-creation behavior. Furthermore, this behavior enhances patron well-being and respect for the hotel. The study contributes to the literature by suggesting a value co-creation behavior model in the hospitality context and empirically examining the antecedents and consequences of this behavior. The results have important implications for managers designing service encounters that can encourage hotel patrons to engage in the value co-creation behavior
Effect of dissolution rate and subsequent ion release on cytocompatibility properties of borophosphate glasses
Get PDFPresent work explores the relationship between the composition, dissolution rate, ion release and cytocompatibility of a series of borophosphate glasses. While, the base glass was selected to be 40mol%P2O5-16mol%CaO-24mol%MgO-20mol%Na2O, three B2O3 modified glass compositions were formulated by replacing Na2O with 1, 5 and 10 mol% B2O3. Ion release study was conducted using inductively coupled plasma atomic emission spectroscopy (ICP-AES). The thermal scans of the glasses as determined by differential scanning calorimetry (DSC) revealed an increment in the thermal properties with increasing B2O3 content in the glasses. On the other hand, the dissolution rate of the glasses decreased with increasing B2O3 content. To identify the effect of boron ion release on the cytocompatibility properties of the glasses, MG63 cells were cultured on the surface of the glass discs. The in vitro cell culture study suggested that glasses with 5 mol% B2O3 (P40B5) showed better cell proliferation and metabolic activity as compares to the glasses with 10 mol% (P40B10) or with no B2O3 (P40B0). The confocal laser scanning microscopy (CLSM) images of live/dead stained MG63 cells attached to the surface of the glasses also revealed that the number of dead cells attached to P40B5 glasses were significantly lower than both P40B0 and P40B10 glasses
Sensor networks and data management in healthcare: emerging technologies and new challenges
Get PDFSmart pervasive sensor networks are becoming an important part of our daily lives. Low-power, high-availability and high-throughput 5G mobile networks provide the necessary communication means for highly pervasive sensor networks, introducing a technological disruption to health monitoring. The meaningful use of large concurrent sensor networks in healthcare requires multi-level health knowledge integration with sensor data streams. In this paper, we highlight some software engineering and data-processing issues that can be addressed by metamorphic testing. The proposed solution combines data streaming with filtering and cross-calibration, use of medical knowledge for system operation and data interpretation, and IoT-based calibration using certified linked diagnostic devices. © 2019 IEEE
Reading collocations in an L2: do collocation processing benefits extend to non-adjacent collocations?
Get PDFVarious studies have consistently shown that collocations are processed faster than matched control phrases, both in L1 and in L2. Most of these studies focused on adjacent collocations (e.g., provide information). However, research in corpus linguistics normally uses a span to identify collocations (e.g., ± 4 words), and these non-adjacent collocations (e.g., provide some of the information) occur very frequently in language. Nevertheless, how they are processed is less established. A recent study on reading non-adjacent collocations seems to suggest similar processing advantages as for adjacent collocations (Author 2016), but this study was limited to the performance of native speakers. The present study addresses the question of whether advanced non-native speakers also show processing advantages for nonadjacent collocations as native speakers do. Forty advanced non-native speakers of English read collocations in either adjacent or non-adjacent conditions, and their eye-movements were recorded. Mixed-effects analysis of their eye-movements was carried out. The results suggest that non-native speakers read adjacent collocations faster than non-formulaic controls, but this facilitation almost disappears for non-adjacent collocations
Technological catching-up, sales dynamics, and employment growth: evidence from China’s manufacturing
Get PDFThis article investigates the microeconomics of employment dynamics, using a Chinese manufacturing firm-level data set over the period 1998-2007. It does so in the light of a scheme of "circular and cumulative causation," whereby firms' heterogeneous productivity gains, sales dynamics and innovation activities ultimately shape the patterns of employment dynamics. Using firm's productivity growth as a proxy for process innovation, our results show that the latter correlates negatively with firm-level employment growth. Conversely, relative productivity levels, as such a general proxy for the broad technological advantages/disadvantages of each firm, do show positive effect on employment growth in the long-run through replicator-type dynamics. Moreover, firm-level demand dynamics play a significant role in driving employment growth, which more than compensate the labor-saving effect due to technological progress. Finally, and somewhat puzzlingly, the direct effects of product innovation and patenting activities on employment growth appear to be negligible. © The Author(s) 2018.

Social Comparisons, Self-Conceptions, and Attributions: Assessing the Self-Related Contingencies in Leader-Member Exchange Relationships
Get PDFResearch on leader-member exchange (LMX) has demonstrated that, in addition to the value of LMX as an indicator of quality relationships with leaders, employees also evaluate how their relationship with the leader compares to other employees’ relationship with the leader. This finding led to the emergence of LMX social comparison (LMXSC). This study examines how LMX vs. LMXSC relates to work outcomes and considers the employee and perceived supervisor self-concept levels as moderators. We posit that LMX predicts work performance through increased organizational commitment. We further suggest that the relational and collective levels of the self-concept act as contingencies of the relationships among LMX, LMXSC, commitment, and performance. A sample of 250 employee-supervisor dyads was used to test the hypotheses. LMX predicted commitment and, indirectly, performance. The employee and perceived supervisor relational self-concepts acted as moderators of LMXSC, and the perceived supervisor collective self-concept acted as a moderator of LMX and LMXSC. However, not all moderation hypotheses were supported. Unexpected moderating effects involving the employee and perceived supervisor individual self-concepts, as well as main effects, were also uncovered. This study helps differentiate LMX from LMXSC and understand the role of self-conceptions, including self-conceptions attributed by employees to the leader, in leader-member relationships
Can direct union elections increase workers’ economic wellbeing in China?: testing effects and explaining mechanisms
Get PDFDirect union elections, a new institutional arrangement in grassroots trade unions in China, have been introduced experimentally in coastal regions since 2000. Using matched employer–employee data, this study examines the effects of direct union elections on workers’ economic wellbeing. Results reveal that 1) union members with directly elected leaders receive higher wages than those without and 2) direct union elections are positively correlated with worker satisfaction. Additional evidences suggest that effects of direct elections work through stronger union leadership and harmonious industrial relations, resembling the voice-response face of unionism. The effect of direct elections significantly weakens or disappears when we exclude the large firms from the analysis. Meanwhile, the effect of union membership regains its significance. We argue that direct elections are a government-sponsored experiment in which large firms are selected to form an incentive-compatible framework among local governments, firms, and workers for explaining union effects with Chinese characteristics
Juggling multiple identities: the untold stories behind a PhD ethnographic study
Get PDFThis article explores the fluidity and dynamicity of a Chinese PhD student’s research experience in negotiating her identities in a longitudinal ethnographic study, first in China and then in the UK. It adopts retrospective and reflexive document analysis of research journals written by her over a 5-year period of overseas study. The analytical framework for the critical reflection of knowledge production synthesizes key concepts of ontology, epistemology, reflexivity, positionality, serendipity, and intersectionality to describe and interpret the researcher’s struggles between insider and outsider, uncertain feelings about different values and beliefs, and emotions due to changing circumstances of family life. The reflexive analysis indicates that PhD students who undertake qualitative studies would function in a far more fluid manner than the often simplistically documented binary roles between an “insider” participant and an outsider researcher in their theses. The article argues that this fluidity in identity shifts and complexity in data collection and analysis are in most cases part and parcel of the research process, which is crucial for researchers to be aware of. Researchers should feel confident to tell the “messy stories” reflexively so as to enhance credibility and trustworthiness of the research findings
Assessing plain and intelligible language in the Consumer Rights Act: a role for reading scores?
Get PDFUnder the Consumer Rights Act 2015 consumer contracts and consumer notices are required to be expressed in plain and intelligible language. This is a difficult concept to capture. Determining whether a contract is expressed in plain and intelligible language involves resource intensive work by regulators and difficult adjudications by courts. This paper explores whether reading scores present a viable alternative. Can a simple computer program tell a consumer, a business, a regulator or the court that a particular contract is not expressed in plain and intelligible language? The paper begins by exploring the concept and role of plain and intelligible language in the Consumer Rights Act, before considering the ways that reading scores have developed and been used in legal contexts. We then report on the findings of an experimental examination of insurance contracts using a basket of reading scores, using our findings to draw conclusions about the utility of reading scores in determining whether a contract is expressed in plain and intelligible language. We find that reading scores can play a role in such determinations, but that further work is needed to provide appropriate tools for business, regulators and courts to use in assessing plain and intelligible language
