Impact of Economic Progress, Energy Consumption and Carbon Dioxide Emissions on Life Expectancy: Evidence from Asia and Africa

In today's society, determining living standards requires taking into account life expectancy. Thus, a key concern for policymakers is the analysis of life expectancy characteristics. The life expectancy is evaluated using the panel quantile regression model across many quantile ranges, including 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 0.95. From 2000 through 2018, the study examines the effects of economic progress, energy use, and carbon dioxide releases on life expectancy across Asia and Africa. The analysis shows that CO2 emanations and life expectancy are intimately linked across all life expectancy quantiles. The impact of economic progress on life expectancy is negative in all except 0.95 quantiles. Additionally, except for the higher quantile (0.95), there is a negative and significant correspondence between hydroelectricity usage and life expectancy in the low and higher quantile series. The findings have thus shown beneficial impacts on life expectancy in low, medium, and greater quantities of petroleum and other liquid consumption. The outcomes suggest boosting the corporate structure to increase productivity and development. However, implementing a clean form of energy sources, i.e., renewable energy and technological efforts, need to employ excellently, contributing to environmental sustainability and a healthy ecosystem.

Lessons Learned From Clinicians and Stroke Survivors About Using Telerehabilitation Combined With Exergames: Multiple Case Study.

BackgroundIn Canada, stroke survivors have difficulty accessing community-based rehabilitation services because of a lack of resources. VirTele, a personalized remote rehabilitation program combining virtual reality exergames and telerehabilitation, was developed to provide stroke survivors an opportunity to pursue rehabilitation of their chronic upper extremity (UE) deficits at home while receiving ongoing follow-up from a clinician.ObjectiveWe aimed to identify the behavioral and motivational techniques used by clinicians during the VirTele intervention, explore the indicators of empowerment among stroke survivors, and investigate the determinants of VirTele use among stroke survivors and clinicians.MethodsThis multiple case study involved 3 stroke survivors with chronic UE deficits and their respective clinicians (physiotherapists) who participated in the VirTele intervention, a 2-month remote rehabilitation intervention that uses nonimmersive virtual reality exergames and telerehabilitation aimed at improving UE deficits in stroke survivors. Study participants had autonomous access to Jintronix exergames and were asked to use them for 30 minutes, 5 times a week. The VirTele intervention included 1-hour videoconference sessions with a clinician 1 to 3 times a week, during which the clinician engaged in motivational interviewing, supervised the stroke survivors’ use of the exergames, and monitored their use of the affected UE through activities of daily living. Semidirected interviews were conducted with the clinicians and stroke survivors 4 to 5 weeks after the end of the VirTele intervention. All interviews were audiorecorded and transcribed verbatim. An abductive thematic analysis was conducted to generate new ideas through a dynamic interaction between data and theory.ResultsThree stroke survivors (n=2, 67%, women and n=1, 33%, man), with a mean age of 58.8 (SD 19.4) years, and 2 physiotherapists participated in the study. Five major determinants of VirTele use emerged from the qualitative analyses, namely technology performance (usefulness and perception of exergames), effort (ease of use), family support (encouragement), facilitators (considerations of the stroke survivors’ safety as well as trust and understanding of instructions), and challenges (miscommunication and exergame limits). During the VirTele intervention, both clinicians used motivational and behavioral techniques to support autonomy, competence, and connectivity. All these attributes were reflected as empowerment indicators in the stroke survivors. Lessons learned from using telerehabilitation combined with exergames are provided, which will be relevant to other researchers and contexts.ConclusionsThis multiple case study provides a first glimpse into the impact that motivational interviewing can have on adherence to exergames and changes in behavior in the use of the affected UE in stroke survivors. Lessons learned regarding the supportive role caregivers play and the new responsibilities clinicians have when using the VirTele intervention may inform the use of exergames via telerehabilitation. These lessons will also serve as a model to guide the implementation of similar interventions.International Registered Report Identifier (IRRID)RR2-10.2196/14629

Knowledge of Network-Based Market Orientation for the Internationalization of Disruptive Innovation in SMEs

Purpose: This study explores the knowledge development of network-based market orientation (MO) for the internationalization of disruptive innovation (DI) by small and medium-sized enterprises (SMEs). Methodology: To manage knowledge development for DI internationalization, a business model was applied to a case study of an individual example. The studied company participated in a series of workshops and allowed on-site visits and interviews for two years in a European Union-funded project. The workshops helped the company to gather MO and networking knowledge and then apply that knowledge internally in the organization and externally, in interactions with suppliers, buyers, and other members of the buyer chain. Findings: Although technological and market efforts usually proceed separately, this study shows that technical and MO knowledge can go together through external and internal networking. Research limitations/implications: To overcome the limitation of having just one example in a case study, several SMEs can be included in future research to produce a comparative analysis. A further study can investigate how technical and market networks can be integrated in the knowledge development process to speed up internationalization. Managers can learn to internationalize DI by collaborating, knowledge sharing, and networking with other SMEs, suppliers, and firms in the buyer chain. Originality: The current study contributes to DI literature by highlighting knowledge generation in SMEs from a process perspective as well as by integrating technical and MO efforts for internationalization.

The price of sustainability: How consumers trade-off conventional packaging benefits against sustainability

Sustainable food packaging alternatives represent an ever-expanding trend on supermarkets' shelves. Despite the technological efforts, a higher sustainability level often comes at the expense of other (perceived) benefits which consumers might not want to sacrifice. While the balance between the benefits and drawbacks of “cleaner” packaging production is central to the designers’ perspective, it is generally overlooked in consumer research. This paper investigates how European consumers cope with product-packaging decisions, when these involve a compromise. Through an online survey with 5035 consumers in five different European countries, our results show that the sustainability appreciation can spill-over to other conventional benefits, such convenience, aesthetic quality or the perceived ability of the packaging to preserve the content. By contributing to sustainability literature and, in particular, to the understanding of the halo and spill-over effect of sustainability, this study shows that positive associations triggered by eco-design elements (e.g., a biodegradable and compostable material) absorb and filter out negative experiences, preventing consumers from perceiving certain drawbacks. This research also provides valuable practical implications to marketers and product designers, by demonstrating how different product categories, packaging types and consumer characteristics, in terms of gender, age, nationality, values and lifestyle, influence product-packaging decisions and their inherent trade-offs.

Shape‐Controlled Solution‐Epitaxial Perovskite Micro‐Crystal Lasers Rivaling Vapor Deposited Ones

AbstractEpitaxial growth methods usually need dedicated equipment, high energy consumption to maintain pure vacuum conditions and evaporation of source materials, and elevated substrate temperatures. Solution epitaxial growth requires nothing of that but is rarely used because the achieved microstructures are of low quality, not homogeneous, and finally exhibit worse performances in devices. Here, an antisolvent‐vapor‐assisted‐crystallization of metal‐halide‐perovskites as a method overcoming these disadvantages is demonstrated. The methylammonium lead tribromide exhibits van‐der‐Waals type of epitaxial growth on mica substrates, resulting in micro‐crystallites whose shape can be controlled to be either triangular micro‐prism or micro‐cuboid. These micro‐crystallites act as optical resonators supporting various optical modes and lasing is achieved under optical excitation with low thresholds and record high environmental stability. Selecting suitable resonators from a large variety of sizes allows control of mode spacing and finally mono‐mode operation, considered to be an important feature of semiconductor laser devices. The achieved results are essentially competitive to those obtained by vapor phase epitaxial microstructures, highlighting that epitaxy of high‐quality optoelectronic device structures is feasible by minimum technological efforts and energy consumption, which are of increasing importance considering issues such as global warming and the current energy crisis.

Disentangling the Effect of Green Manufacturing Practices on a Firm’s Economic Performance

This article explores the impact of green manufacturing practices, in the form of green activities, green investments, and the type of product made, on the economic performance of firms. Using survey data from European small- and medium-sized enterprises (SMEs), we investigate the extent to which the number of green activities, green investments and type of product made affects a firm’s economic performance. Our results reveal that while the number of green activities has a positive effect on economic performance, the amount of green manufacturing investments has an inverted U-shaped relationship to economic performance, and that this effect is positively moderated if a company also sells non-green products. Building on self-determination theory, we argue that consumers react positively to green business practices because they accurately assess technological efforts that seek to mitigate the environmental type of “grand societal challenges” that we are currently facing. Our study contributes to the literature on green manufacturing by dissecting the effect of green manufacturing practices on a company’s economic performance. Our study findings also provide managers with advice on the right balance of green practices that most benefit their companies.

Improving problem-solving skills through technology assisted collaborative learning in a first year engineering mathematics course

PurposeThe purpose of this research study is to explore simple collaborative technique for teaching mathematics and thus improving the problem solving skills of the students. Better pedagogic activities are required to motivate the students to perceive mathematics as a subject that stimulates problem-solving skills required for engineers.Design/methodology/approachThis paper presents a research study on the application of technology-supported collaborative learning in improving the problem-solving skills of first-year engineering students in a mathematics course.

Practice of collaborative learning is made easy with simple technology. The solutions recommended are practically feasible and does not require any special infrastructure or specific training.

Definitions and implications of climate-neutral aviation

To meet ambitious climate targets, the aviation sector needs to neutralize CO2 emissions and reduce non-CO2 climatic effects. Despite being responsible for approximately two-thirds of aviation’s impacts on the climate, most of aviation non-CO2 species are currently excluded from climate mitigation efforts. Here we identify three plausible definitions of climate-neutral aviation that include non-CO2 forcing and assess their implications considering future demand uncertainty, technological innovation and CO2 removal. We demonstrate that simply neutralizing aviation’s CO2 emissions, if nothing is done to reduce non-CO2 forcing, causes up to 0.4 °C additional warming, thus compromising the 1.5 °C target. We further show that substantial rates of CO2 removal are needed to achieve climate-neutral aviation in scenarios with little mitigation, yet cleaner-flying technologies can drastically reduce them. Our work provides policymakers with consistent definitions of climate-neutral aviation and highlights the beneficial side effects of moving to aircraft types and fuels with lower indirect climate effects. Non-CO2 effects must be addressed for climate-neutral aviation but are currently ignored in international climate policies. The authors provide a framework with different definitions of climate neutrality, then show how technological and demand-side mitigation efforts can help to achieve these targets.

Global Sustainability Index (GSI) construction: an evaluation tool for public policies directed at sustainable milk production in contemporary time

Sustainable development refers to agricultural and industrial activities and the understanding of sustainability assumes greater complexity, which requires economic, social, environmental, institutional, technological, cultural and geographical emphasis to be considered, because what is sustainable for one region may not be for another. The article aims to show methodological criteria for the construction of the Global Sustainability Index (GSI) and its importance in the evaluation of public policies of sustainable milk production in contemporary times. The methodology considers the economic, social, environmental, institutional and technological dimensions, for better assessing the sustainable of economically active activities. The survey took place in Rondônia with 400 dairy farmers, where we obtained the GSI that achieved average sustainability, GSI = 0.42. The economic dimension presented an index of 0.52, being the most sustainable among the analyzed dimensions. Following the decreasing order, comes the social and environmental, with average sustainability of 0.44 and 0.41, and, with low sustainability, was the technological dimension, which showed an index of 0.39, and, the institutional with 0.32 decimal points of sustainability. This result indicates the need for political and technological efforts for better performance in the sector.

Progress towards enhanced access and use of technology during the COVID-19 pandemic: A need to be mindful of the continued digital divide for many rural and northern communities.

The COVID-19 pandemic produced unprecedented adoption and deployment of technology in rural and northern areas; however, this expansion widened the digital divide for many. Evidence shows that older adults’ use of technology has increased. Coupled with an increasing number of available technologies to enhance healthcare delivery, social engagement, meaningful activities, and support to carers, we are at a crossroads for change. Emerging strategies used by organizations to promote technology and support efforts to bridge and close the digital divide are discussed. In a post-pandemic society, policy-makers can play a critical role to ensure that improvements, efficiency gains, and lessons learned are fully leveraged to reap the benefits of technology use by older adults, care partners, and the healthcare system. Recommendations are given for policy-makers to capitalize on this opportunity to narrow the digital divide for those in rural and northern communities.

Analysis of User Acceptance of Open Source Software (OSS) Using Task Technology Fit (TTF) and Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) Model

OSS OPAC UNTAN is a joint catalog used to carry out the collection search process at the Tanjungpura University library. However, there are still many shortcomings of the system that are felt by users and librarians, such as a less interactive display and less accurate information. This indirectly affects users in using the system, so this research was conducted to determine the extent of user acceptance of OSS OPAC UNTAN and what factors influence users in using OSS OPAC UNTAN. The model used is the integration of the Task Technology Fit (TTF) model and the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2). The data analysis technique uses the Partial Least Square–Structural Equation Modeling (PLS-SEM) approach with the help of SmartPLS 3 tools. The results of this study indicate that there are 5 accepted hypotheses from 12 hypotheses that have been built with the Habit model factor, Task Technology Fit, Effort Expectancy, Performance Expectancy, and Technology Characteristics have a significant effect on user acceptance. The results of the research are an evaluation of the UNTAN OPAC OSS in the hope that it can be used as a decision-making for the developer in improving the characteristics of technology, features, and services so that they can be utilized by users and operate optimally.Keywords: User Acceptance, OPAC, PLS-SEM, TTF, UTAUT 2

A qualitative system dynamics perspective on the contribution of information technology credibility towards business and information technology alignment

Purpose: The dynamic interdependence between the deployment of technological assets and organisational performance remains a challenge for modern enterprises. Organisations reinforce competitiveness and improve performance when business activities and information technology (IT) efforts are aligned. The credibility of the IT organisation is an important influence on alignment. This research guides managers and directs future research to improve IT credibility.Design/methodology/approach: Interviews with senior leaders about factors influencing IT credibility provided rich data for analyses. The dynamic complexity of creating a credible IT function to ensure alignment was captured using qualitative system dynamic diagrams. A causal loop diagram was constructed to identify feedback loops and leverage points.Findings: The analysis confirms the impact of three factors identified by prior research. It provides a new perspective on portfolio-level IT governance’s contribution to establishing credibility. The value of using past failure to develop credibility through ownership and resolution emerged from the analysis.Practical implications: The results provide guidelines to improve the IT organisation’s credibility to improve business and IT alignment. Leverage points to improve credibility are provided, and research into resolving past failure as a mechanism to success is suggested.Originality/value: While most of the extant literature focused on static alignment factors, causal loop diagrams provided insight into IT credibility’s systemic nature. A new factor (resolving past failure), a new perspective (portfolio level governance), and confirmation of existing factors and identifying leverage points contribute to practice and science.

Dietary Change and Global Sustainable Development Goals

Food production for human consumption is a leading cause of environmental damage in the world and yet over two billion people suffer from malnutrition. Several studies have presented evidence that changes in dietary patterns across the world can lead to win-win outcomes for environmental and social sustainability and can complement ongoing technological and policy efforts to improve the efficiency of agricultural production. However, the existing evidence have been compiled in “silos” by a large range of researchers across several disciplines using different indicators. The aim of this quantitative review is to bring together the existing knowledge on heterogeneity of current dietary patterns across the world and how a transition toward healthy diets in different countries can aid in progress toward multiple global Sustainable Development Goals (SDGs). We first summarize the nutritional quality, economic cost, and environmental footprint of current diets of over 150 countries using multiple indicators. Next, we review which shifts in dietary patterns across different world regions can help toward achievement of SDG2 (Zero hunger), SDG3 (Good health and wellbeing), SDG 6 (Clean water and sanitation), SDG13 (Climate action), SDG14 (Life below water), and SDG15 (Life on land). Finally, we briefly discuss how to enable the shift toward sustainable dietary patterns and identify the research and data gaps that need to be filled through future efforts. Our analysis reveals that dietary change is necessary in all countries as each one has unique priorities and action items. For regions such as Sub-Saharan Africa and South Asia, increased intake of nutrient dense foods is needed to address deficiency of essential nutrients like folate, potassium, and vitamin A. For North America and Europe, shifting toward more plant-based diets would be healthier and simultaneously reduce the per capita environmental footprints. The results can be useful for policymakers in designing country-specific strategies for adoption of sustainable dietary behaviors and for food industry to ensure the supply of sustainable food items customized with regions' need.

Impacts of green and preservation technology investments on a sustainable EPQ model during COVID-19 pandemic

Carbon and Sulfur dioxides emissions are the key issues of global warming that affects on human health. Emissions cap- and -trade policy is a key mechanism implemented in several countries to reduce the emissions. Nowadays, public gathering is restricted due to the pandemic situation caused by COVID-19. As a result, people are facing huge problems in their regular activities and lifestyle. During the lockdown periods, demands for few merchandises decrease and the deterioration rate increases. Moreover, because of the unavailability of raw materials and labours during the lockdown, shortages occur at the manufacturing company. Keeping these problems in mind, a multi-objective sustainable economic production quantity model is proposed with partially back-ordering shortages, in which the effects of sustainability are investigated. To handle the demand fluctuation throughout the current pandemic, emergency level dependent demand rate is assumed. To reduce greenhouse gases emissions and deterioration rate, investments in green technology and preservation technology efforts are used. The objectives of this study are to maximize the manufacturer’s profit and minimize the greenhouse gases emissions for producing green products. The multi-objective model is solved by utilizing the fuzzy goal programming approach. The mathematical model is illustrated by four numerical examples. The main finding of the work is that under both green and preservation technologies investments, a sustainable model with partially back-ordering shortages and lockdown level dependent demand rate decreases justifiable greenhouse gases emissions and increases the product’s greening level. The results indicate that the system profit is increased by 16.1% by investing in both preservation and green technology. Furthermore, a sensitivity analysis is performed along with some managerial insights for practitioners. Finally, the paper is ended with conclusions and future research tips.

Doped silica sol layer coatings on evanescent field fiber Bragg gratings for optical detection of nitroaromate based explosives

Evanescent field etched fiber Bragg gratings (eFBG) were prepared with doped and non-doped nanoporous silica sol coatings for optical detection of the nitroaromatic explosives 2,4-dinitrotoluene (DNT), 1,3-dinitrobenzene (DNB) and trinitrotoluene (TNT). We used 3-aminopropyltrimethoxysilane (APTMS) and tetrabutylammonium hydroxide based receptors (TBAH, C16H37NO) as dopants in order to increase the specific identification of the nitroaromates. In nitroaromatic trace gas atmosphere the induced wavelength shift of the Bragg reflection signal was highest for the sensor with TBAH-doped silica sol receptor coating. Within the first two minutes during exposure the change of the signal intensity, reflecting the adsorption dynamics of the nitroaromatic explosives, was most significant and characteristically depending on the type of receptor dopant used. The cross sensitivities of the sensor with TBAH-doped silica sol receptor coating with four common solvents like acetone, ethanol, 2-propanol and tetrahydrofuran (THF) in comparison to the sensitivity of the tested explosives was more than six orders of magnitude (106) lower than that of solvents, indicating a very high selectivity of the sensor. By applying a simplified diffusion model correlated to a series of measurements with different distances to the target we estimated the limit of detection for a sensor coated with TBAH doped silica sol with 35.8 ± 0.9 ppb for DNB and 140.2 ± 1.8 ppb for DNT in air at room temperature. Using a more etched FBG (but mechanically less robust) sensor we were able to detect TNT as well at concentrations about 5 ppb at room temperature in air. A major result of our investigations was to demonstrate, that the nanoporous silica sol host matrix is suited for fast adapting with low technological effort the affinity of the receptor coating for silica-based evanescent field sensors. For future applications a set of sensors of silica-sol coatings with different dopants in combination with pattern recognition of the sensor signals could be used for clear identification of explosives.

Big data, big changes? The technologies and sources of data used in science classrooms

AbstractWith improving technology and monitoring efforts, the availability of scientific data is rapidly expanding. The tools that scientists and engineers use to analyse data are changing in response. At the same time, science education standards have shifted to emphasize the importance of students making sense of data in science classrooms. However, it is not yet known whether these exciting new datasets and tools are used science classrooms, and what it would take to facilitate their use. To identify opportunities, research is needed to capture the data practices currently performed in classrooms, and the roles of technology for student learning. Here, we report findings from a survey conducted in the United States of 330 science teachers on the data sources, practices and technologies common to their classroom. We found that teachers predominantly involve their students in analysing relatively small data sets that they collect. In support of this work, teachers tend to use the technologies that are available to them—namely, calculators and spreadsheets. In addition, we found that a subset of teachers used a wide variety of data sources of varying complexity. We discuss what these findings suggest for practice, research and policy, with an emphasis on supporting teachers based on their needs.Practitioner notesWhat is already known about this topic Collecting and analysing data are central to the practice of science, and these skills are taught in many science classrooms at the pre‐collegiate (grades K‐12) level. Data are increasingly important in society and STEM, and types and sources of data are rapidly expanding. These changes have implications for science teachers and students. What this paper adds We found that the predominant data source science teachers use is student‐collected, small data sets. Teachers use digital tools familiar and available to them: spreadsheets and calculators. Teachers perceive the cost and time it would take to learn to use digital tools to analyse data with their students as key barriers to adopting new tools. Despite the predominance of small, student‐collected data analysed using spreadsheets or calculators, we also found notable variability in the data sources and digital tools some teachers used with their students. Implications for practice and/or policy Many of the changes called for in science education standards and reform documents, regarding how students should collect and analyse data, have not yet been fully realized in pre‐collegiate classrooms. Science teacher educators and science education researchers should build curricula and develop digital tools based on which kinds of data sources and digital tools teachers presently use, while encouraging more complex data useage in the future.

Emotions in climate change communication: An experimental investigation

AbstractWe conducted an experiment to test whether altering the saliency of information provided by experts in fictitious news stories on climate change triggered different emotions among readers. Based on appraisal theories of emotions in the psychology literature, we hypothesized that 1) news stories that presented climate change related threats as diffuse and uncertain would elicit greater levels of anxiety, while 2) stories that provided a specific target to blame would induce greater anger, and 3) those that underlined the potential of technology and human efforts to solve climate change related issues would elicit greater levels of hope. We found that while all news stories concerning climate change elicited high levels of anxiety, there were statistically significant differences between the emotions expressed by participations in the expected directions. We discuss the potential implications of these findings for climate change communication and for public opinion on climate change.
