Published: February 2020

AbstractRaman imaging has become an attractive technology in molecular biology because of its ability to detect multiple molecular components simultaneously without labeling. Two major limitations in accurately accounting for spectral features, viz. background removal and spectral unmixing, have been overcome by employing a modified and effective routine in multivariate curve resolution (MCR). With our improved strategy, we have spectrally isolated seven structurally specific biomolecules without any post-acquisition spectral treatments. Consequently, the isolated intensity profiles reflected concentrations of corresponding biomolecules with high statistical accuracy. Our study reveals the changes in the molecular composition of lipid droplets (LD) inside HuH7 cells and its relation to the physiological state of the cell. Further, we show that the accurate separation of spectral components permits analysis ofin vivostructural modification of molecules after cellular uptake. A detailed discussion is presented to highlight the potential of Raman spectroscopy with MCR in semi-quantitative molecular profiling of living cells.
Safe food refrigeration knowledge, attitudes, and practices of university students
Authors: Obande David , Young Ian 
Published: February 2020

PurposeStudents living in university residence halls often have refrigerators for food storage, and are often living alone and handling food for the first time in their lives. Therefore, an investigation of their safe food storage practices is important to help prevent food-borne illness in this population. This research seeks to evaluate the food safety knowledge, attitudes and practices related to food storage and refrigeration among undergraduate students at a university campus.Design/methodology/approachA cross-sectional study was conducted by administering a questionnaire to undergraduate students (n = 93) living in two residence halls on a university campus.FindingsMany respondents (43.3 percent) were unaware of the maximum temperature a refrigerator should be set at to prevent microbial growth, while 83.7 percent reported ‘never’ or ‘rarely’ checking the temperature of their refrigerator using a thermometer. Many respondents (43.1 percent) incorrectly ‘agreed’ or ‘strongly agreed’ that the smell and appearance of food can be used as an indicator for food safety, and 64.1 percent self-reported often or always using this practice. Respondents that were born outside of Canada had more positive food storage attitudes, while those that identified as Caucasian had higher knowledge scores. A positive correlation was identified between knowledge and attitude scores (r = 0.217) but neither were significantly associated with practice scores.Originality/valueThe study revealed gaps in the knowledge, attitudes and practices of university students living in residence halls related to safe food storage. Hence, there is a need to increase awareness and education in this population on key food storage practices.

Roadblocks to university education for diploma engineers in Bangladesh
Authors: Alam Gazi Mahabubul , Forhad Md. Abdur Rahman 
Published: February 2020

PurposeDiploma Engineers (DE) mainly receive practical and skills-oriented education and training in the area of technical and vocational subjects from the polytechnic system. Globally, universities have limited DEs access to Higher Education (HE). Over the course of time, many countries have changed this situation, putting into place a decent qualification and policy framework that ensures higher education for deserving candidates. Lately, Technical and Vocational Education and Training (TVET) received special priority in developing countries, and Bangladesh is no exception to it, resulting in a massive growth of DE. This study, the first of its kind, examines the impact of this growth with a key focus on the inclusion of diploma engineers into higher education.Design/methodology/approachGiven the differentiated nature of research questions, multiple techniques are used to collect the data. However, this research uses the qualitative method. Both secondary and primary data are used. While secondary data are collected by the Bangladesh Bureau of Educational Information and Statistics (BANBEIS), primary data are collected through interviews. With standard sets of admission questions, tests are conducted with two groups of students to draw a comparison.FindingsThe number of students studying at polytechnic institutes is increasing dramatically. The growth of public polytechnic institutes remains steady. Public counterparts respond to the demand by operating both day and night shifts. Many private polytechnics are also established. The size and infrastructure of private Polytechnics are relatively insignificant. However, the mushrooming private sector covers the increased demand. The curve of DE has been increased radically with a questionable competency by the contribution of both public and private polytechnics. Only one public university provides higher education to these DE.Originality/valueA few reports have been published in the area of TVET by the development partners and the Government of Bangladesh. Only one journal article is published exploring the role of TVET on national development in Bangladesh. However, none cover the issue of access to university education for DE graduates.
TiO2-Ag/blood hybrid nanofluid flow through an artery with applications of drug delivery and blood circulation in the respiratory system
Authors: Shojaie Chahregh Hamidreza , Dinarvand Saeed 
Published: February 2020

Purpose
As transferring biological fluid through an artery is nowadays a pivotal subject, the purpose of this paper is to study the mathematical model of hybrid nanofluid flow comprising pure blood as base fluid and TiO2 and Ag as nanoparticles through the porous channel, which can be an applicable model for drug delivery.

Design/methodology/approach
Both walls of the channel have different permeability, which enables the fluid to enter and exit, and variable height, which dilates and squeezes at the uniform rate. By taking advantage of the similarity transformation technique, governing equations have been converted into a system of the non-linear ordinary differential equation. This problem is solved numerically by utilizing BVP4C built-in function in MATLAB software to explore the impacts of pertinent parameters.

Findings
The plots of velocity and temperature profile, normal pressure distribution and wall shear stress, as well as Nusselt number for involved parameters, are presented and the logic and physical reasons beyond them are highlighted. It has been observed that the asymmetry of the channel, caused by different permeability at walls, affects the nature of flow significantly.

Originality/value
To the best of the authors’ knowledge, no one has ever attempted to study the flow through a deformable porous channel with blood as a base fluid and as hybrid nanoparticles to describe medical phenomena and treatment applications. Indeed, the achievements of this paper are purely original and the numerical results were never published by any researcher.

Design/methodology/approach
In the present qualitative study, 19 policymakers in different levels of the disaster management organizations were selected based on purposive sampling. Semi-structured and face-to-face interviews were used to identify the participants’ views. The findings were analyzed using thematic analysis.

Findings
The present situation and the challenges of the mitigation phase were the main themes in this study. Risk perception, training and media were the sub-themes. Political, legal, social and cultural challenges of the mitigation phase were also sub-themes.

Originality/value
The findings of this study indicated that different aspects should be considered to minimize the risk of earthquake. In addition, all kinds of media, including visual, written, audio, instrumental, group and multimedia, should be used for enhancing public awareness so that readiness for earthquakes can be considered as a permanent mission of the citizens, who are always concerned about earthquakes.
Internship models: acknowledging social and academic expectations
Authors: Barrón Nancy Guerra 
Published: February 2020

PurposeThe paper shows an example of an internship-classroom model that increases student motivation and self-efficacy across cultural frameworks by providing opportunities for application projects.Design/methodology/approachThe author uses qualitative data collected through teacher research and focuses on the rhetorical context to show how disciplinary writing courses can be redesigned by incorporating theoretical frameworks from business management and psychology.FindingsClient projects used in disciplinary writing courses, in conjunction with national narratives on higher education as a gateway to higher pay and better skills, improve student self-efficacy if faculty redefine their roles as mediators, and if students are treated as interns and knowledge workers.Practical implicationsThe integration of non-academic approaches from business management with academic expectations of research, revision, and rehearsal for a specific client shows how purposeful client-based projects can influence student motivation, self-efficacy, and sense of self-worth that are crucial for diverse student populations. Expanding the theoretical frameworks for successful teaching is an effective model for increasing students' competence as disciplinary writers.Originality/valueAn interdisciplinary approach that draws from academic fields as well as from the business world provides new ways of working successfully with students and preparing them for writing inside and outside the classroom. Incorporating an internship approach into a classroom setting encourages teachers to reimagine student, client, and faculty roles.

Superior position equal to greater influence? The moderating role of technological complexity
Authors: Sun Yaowu , Gong Xiaoye 
Published: February 2020

PurposeTechnological standardization can promote the development of complex products and systems (CoPS) (e.g. large aircraft, high-speed trains). Many studies argue that a superior network position contributes to improving a firm's ability to innovate; however, few studies have considered the aforementioned line of research as falling under the purview of CoPS standardization. This study focuses on CoPS integrators, which hold the most important enterprise roles in CoPS manufacturing and innovation, to analyze whether the two types of superior positions (i.e. the central position and the brokerage position) help the integrator influence the standardization process in a process moderated by technological complexity.Design/methodology/approachConsidering the outstanding market performance of the railway transportation industry in China, the abundance of cooperative activities in this industry, and data availability, we adopt integrators from this industry as samples for the empirical analysis in this study. A negative binomial regression analysis with random effects was conducted to analyze the acquired panel data.FindingsThe results show that the central position has an invertedU-shaped effect on the integrator's ability to influence standardization and that the brokerage position has a positive effect. We also find that the underlying mechanism of the two types of network positions impacts the integrator's ability to influence standardization and that it has two modes: knowledge integration in related domains and knowledge integration in nonrelated domains. Moreover, technological complexity attenuates the effect of the central position and strengthens the effect of the brokerage position on the integrator's ability to influence standardization.Originality/valueThis paper contributes to the theoretical research on CoPS manufacturing and innovation and complements knowledge-based theory. The results could prove enlightening for integrators facing complex technological environments, allowing them to establish a reasonable external knowledge search strategy and choose appropriate cooperation partners according to their knowledge domains.

Authors: Smith Julie , Garriety Susan 
Published: February 2020

Purpose
Being successful in a rapidly changing world of work depends upon having very clear insights into the nature of the workforce from top leadership to lowest employee levels. Understanding generational similarities and differences provides a good starting point, as it provides the basis for examining the diversity of generational perspectives and needs and insight and instruction to open the thinking about the diverse population of employees. The purpose of this paper is to explore ways to bridge the five generations that work in today’s workforce.

Design/methodology/approach
Human resources has an especially important role to play in employee policy development and implementation, employee relations, performance evaluation, career progression and a wide range of other equally important and complex situations.

Findings
While it is important to understand these broad generations, it is critical to engage with the individuals within your organization to better understand their perspectives, what matters most to them and where they see the greatest challenges and opportunities to bridge across generations. This paper explores approaches to take in bridging these generations.

Originality/value
This paper will offer readers valuable insight into managing a multi-generational workforce.
Domain I of hepatitis C virus NS5A associates with ACBD3 in a genotype‐dependent manner
Authors: Lu Yue , Yang Xiaojie , Zhang Leiliang 
Published: February 2020

AbstractPreviously, it was found that the hepatitis C virus NS5A interacted with ACBD3 in a genotype‐dependent manner. However, the region in NS5A responsible for association with ACBD3 is not clear. Domain I of NS5A was identified as critical for ACBD3 binding. By comparing the differences of amino acids in domain I from different genotypes of NS5A, it was found that key amino acids potentially corresponded to the affinity of the NS5A‐ACBD3 interaction. The findings not only revealed that domain I of NS5A associates with ACBD3 but they also shed mechanistic light on how NS5A is associated with ACBD3 in a genotype‐dependent manner.
Timing and duration of phenological resources: Toward a mechanistic understanding of their impacts on community structure and ecosystem processes in stream food chains
Authors: Takimoto Gaku , Sato Takuya 
Published: February 2020

AbstractPhenological resources are common across many ecological communities, and can strongly affect community dynamics. Recent field manipulation experiments in stream food chains found that seasonal timing and duration of terrestrial prey inputs affected the feeding behavior, growth, and maturation of fish predators, caused predator‐mediated indirect effects on aquatic prey, and modified trophic‐cascading effects on ecosystem processes (i.e., litter decomposition). These experiments described impacts of resource phenological changes over a few month period, but long‐term impacts of continued changes in resource phenology are unknown. Here, we develop a mathematical model to extrapolate long‐term predictions about the effects of changes in resource phenology from the results of field manipulation experiments. The model predicts that advanced timing generally decreases aquatic prey and litter processing and prolonged duration will either increase or decrease aquatic prey and litter processing depending on the total amount and pre‐disturbed timing and duration of terrestrial prey inputs. Our modeling approach clarifies that stage‐specific responses of life history processes in fish (i.e., growth, maturation, and reproduction) to phenological changes in terrestrial prey inputs mediate indirect effects on aquatic prey and litter processing. We argue that stage‐specific responses of life history processes are an integral part of the mechanisms with which to predict the consequences of phenological species interactions at the community and ecosystem levels.
Executive Compensation, Sustainable Compensation Policy, Carbon Performance and Market Value
Authors: Haque Faizul , Ntim Collins G. 
Published: February 2020

AbstractWe examine the interrelationships among executive compensation, environmental‐social‐governance‐based (ESG) sustainable compensation policy, carbon performance and market value. Using one of the largest datasets to date, consisting of 4379 firm‐year observations, covering a period of 15 years (2002–2016) from 13 industrialized European countries and insights from neo‐institutional theory (NIT), our findings are fourfold. First, our results suggest that process‐oriented carbon performance is positively associated with market value, whereas actual carbon performance has no effect on market value. Second, we show that the market value–process‐oriented carbon performance nexus is moderated by executive compensation. Third, our results indicate that executive compensation has a positive effect on process‐oriented carbon performance, but has no similar effect on actual carbon performance. Fourth, we show that the process‐oriented carbon performance–executive compensation nexus is reinforced for companies that adopt ESG‐based sustainable compensation policy. Our results are generally robust to controlling for governance mechanisms, alternative measures/estimations and endogeneities. Overall, our evidence supports the legitimization aspect of NIT and suggests that the market tends to reward firms with superior process‐oriented carbon performance instead of undervaluing firms with excessive actual carbon emissions. This implies that firms appear to use incentive‐based mechanisms to symbolically improve their process‐oriented carbon performance without substantively improving their actual carbon performance.
