Abstract

Purpose

The aim of the study is the question, that is, which evaluation method for the measured temperature profile is more suitable and feasible for quantitative thermometry (QT): A simple measurement setup based on 3-point temperature sensing by means of semiconductor sensors (NTCs) or thermographic methods which offer 2-dimensional (2D) temperature measurements of the sample with good spatial resolution but an inferior temperature sensitivity. What experimental effort is required to adjust the test setup to satisfy the boundary conditions of the underlying thermodynamic equations?

Design/methodology/approach

In this paper results of both methods are contrasted and the error of QT measurement is assessed by finite element analysis (FEA) in this follow-up.

Findings

The low-cost NTC method allows a straightforward determination of a lower estimate of the fatigue strength with only a very small measurement error. Even asymmetries in the thermal boundary conditions of the test setup are broadly tolerated, as well as a lack of thermal isolation.

Practical implications

The method is restricted to metallic materials without phase transitions during fatigue in the fatigue strength regime.

Originality/value

QT is not a new method. The assessment of the methods proposed in the literature regarding their practicability in terms of accuracy is innovative focus of this work. Nevertheless, highly accurate thermometric measurements can be performed by using simple commercial sensors in combination with a standard digital multimeter.

Abstract

Purpose

Literature on packaged food consumption and associated factors in Kerala is limited. This study aims to find out consumption pattern of packaged food and the factors associated with it among young adults in Kerala.

Design/methodology/approach

The authors conducted a cross-sectional survey among 384 young adults aged 18–30 years selected using multistage cluster sampling. Information on packaged food consumption and sociodemographic factors was collected using a structured, pre-tested interview schedule. Binary logistic regression analysis was done to find out the factors associated with packaged food consumption.

Findings

Among the participants, 85.7% (95% CI = 81.9%–88.9%) reported consuming packaged food at least once a week, and 45% (95% CI = 40.4%–50.3%) reported consuming packaged food more than two times a week. Individuals who were employed [adjusted odds ratio (AOR) = 1.71, 95% CI = 1.06–2.76], who consume packaged food without a fixed routine (AOR = 2.24, 95% CI = 1.18–4.28), those without previous attempts to reduce packaged food consumption (AOR = 3.45, 95% CI = 1.72–6.91) and those who preferred packaged food for their taste and flavor (AOR = 1.73, 95% CI = 1.09–2.74) had greater odds of consuming packaged food more than two times a week compared to their counterparts.

Originality/value

Packaged food is frequently consumed by more than 40% of young adults in Kerala. Efforts focused on individuals (such as building awareness and taxing packaged foods) are warranted to control packaged food consumption among young adults.

Abstract

Purpose

COVID-19 vaccinations face a backdrop of widespread mistrust in their safety and effectiveness, specifically via social media platforms which constitute major barriers for the public health sector to manage COVID-19 (and future) pandemics. This study provides a more nuanced understanding of the public's engagement behavior toward COVID-19 vaccinations.

Design/methodology/approach

Using Netnography, this study explores the public's interactions with vaccine communications by the WHO via Facebook. From WHO posts about the COVID-19 vaccination 23,726 public comments on Facebook were extracted and analyzed.

Findings

Building on crisis communication, health and engagement literature, this paper identifies and conceptualizes seven patterns of engagement behavior toward the COVID-19 vaccination and develops the first framework of relationships between these patterns and the extant vaccine attitudes: vaccine acceptance, hesitancy and refusal.

Practical implications

This paper helps policymakers identify and adapt interventions that increase vaccine confidence and tailor public health services communications accordingly.

Originality/value

This research offers the first typology of patterns of engagement behavior toward COVID-19 vaccinations and develops a framework of relationships between these patterns and the existing understanding in health literature. Finally, the study provides data-driven communication recommendations to public health service organizations.

Abstract

Purpose

This paper aims to carry out a literature review on the implementation of digital preservation policies, strategies and actions by institutional repositories. The objective is to identify, out of the published experiences, at which level they are fulfilling the function of ensuring the long-term availability of the deposited materials.

Design/methodology/approach

Using a systematic literature review methodology, a total of 21 articles from international refereed journals published between 2009 and 2020 are reviewed.

Findings

The research production on this subject is very limited. The scarce number of published articles proves that the interest of repository managers has been focused on issues other than to assure the long-term availability of the assets they store. The literature review has not found clear evidence about how institutional repositories are implementing digital preservation. It is particularly striking the lack of works focused on the situation in European countries. More field studies are needed. They would allow to extract conclusions and produce best practices to help managers to improve preservation strategies.

Originality/value

This study has shown that one of the main functions of repositories is not being dealt with as promised by repository managers. More work in this area is needed. In particular, it is necessary for a study at the European level to gather detailed data that will allow to draw a portrait of the current situation, extract conclusions and produce best practices to help managers to improve or develop preservation strategies.
