Studies with e-textile sensors embedded in garments are typically performed on static and controlled phantom models that do not reflect the dynamic nature of wearables. Instead, our objective was to understand the noise e-textile sensors would experience during real-world scenarios. Three types of sleeves, made of loose, tight, and stretchy fabrics, were applied to a phantom arm, and the corresponding fabric movement was measured in three dimensions using physical markers and image-processing software. Our results showed that the stretchy fabrics allowed for the most consistent and predictable clothing-movement (average displacement of up to −2.3 ± 0.1 cm), followed by tight fabrics (up to −4.7 ± 0.2 cm), and loose fabrics (up to −3.6 ± 1.0 cm). In addition, the results demonstrated better performance of higher elasticity (average displacement of up to −2.3 ± 0.1 cm) over lower elasticity (average displacement of up to −3.8 ± 0.3 cm) stretchy fabrics. For a case study with an e-textile sensor that relies on wearable loops to monitor joint flexion, our modeling indicated errors as high as 65.7° for stretchy fabric with higher elasticity. The results from this study can (a) help quantify errors of e-textile sensors operating “in-the-wild,” (b) inform decisions regarding the optimal type of clothing-material used, and (c) ultimately empower studies on noise calibration for diverse e-textile sensing applications.

The Relationship

Abstract This study conducted in Florida examines the relationship between an individual’s social connections and their decision to evacuate during a hurricane warning. Using Hurricane Matthew in 2016 as a case study, a survey was conducted on two groups (those who evacuated and those who did not), assessing one’s social connections considering three dimensions: dependability, density, and diversity. These factors, in addition to socioeconomic variables (e.g., age, race, education), were used to better define a picture for what influences evacuation decision-making. To avoid memory decay, the surveys were completed at the time of the evacuation for those who evacuated and immediately after the passage of Matthew for those who did not evacuate. It was concluded, through statistical analyses, that the perceived dependability of a person’s social connections (i.e., their perceived access to resources and support) played a significant role in the decision to evacuate or not, with non-evacuees having more dependable relationships and having a tightknit community they can rely on during a storm event. On the other hand, the density and diversity of peoples’ social connections did not significantly impact the decision to evacuate. This study has important implications for adding to the knowledge base on community-based sustainable disaster preparedness and resilience.

The Impact

This article uses a case-study approach to discuss the effects of Chinese economic engagement on three dimensions of human capital development: local employment, training and skill building, and knowledge and technology transfer. The study findings suggests that Chinese economic engagement can and does contribute to human capital development in Africa; however, this is dependent on certain sectoral factors and contextual conditions. This study advances a working hypothesis that the human capital development impact of Chinese economic engagement will vary across countries and sectors of the African economy. This working hypothesis seeks to guide further research towards developing a theoretical framework for the study of Chinese economic engagement in Africa and its effects on human capital development. The article also identifies research areas that should be further explored in order to gain a deeper understanding of the impact of Chinese economic engagement in Africa.

Abstract Businesses establish supply chains in order to continue their activities. Choosing the suppliers to take part in these supply chains poses many challenges in rapidly changing conditions. Environmental concerns in the public, competitive market structures, and developing technological opportunities affect the decision-making processes. Different criteria are taken into consideration instead of traditional criteria such as cost and service. In this study, green, agile, and Industry 4.0 dimensions and the criteria under these dimensions are defined. According to these, the problem of selecting the supplier that responds to the expectations of the markets and enables them to increase their competitiveness was discussed. Fuzzy SWARA and fuzzy BMW methods were applied in an integrated way to solve the supplier selection problem under these three dimensions. A real case study was also presented. In the study, the results obtained by creating different scenarios were compared and sensitivity analysis was made. The results obtained show that the hybrid method developed in this study is effective in supplier selection problems. As a result of the study, the most important evaluation dimension is "agile" and the most important criterion is "delivery speed".

Case Study Data

Although efforts for developing e-democracy have been underway for over a decade, recent literature indicates that its uptake by citizens and Elected Members (EMs) is still very low. This paper explores the underlying reasons for why this is so from the perspective of local EMs in the context of UK local authorities. It draws on findings reported in earlier works supplemented with primary case study data. Findings are interpreted through the lens of Giddens structuration theory, which assists in drawing out issues related to three dimensions of human agency: communication of meaning, exercising power and sanctioning behaviour. The paper abstracts categories of agency from the findings and uses these to formulate eight propositions for creating an e-friendly democratic culture and enhancing EMs uptake of e-democracy. These propositions provide an indication for future e-democracy research direction.

Knowledge Preservation

Knowledge Management is a diverse field of study, dealing in the facilitation of knowledge sharing, the creation of knowledge systems, knowledge transfer, and knowledge preservation. Information professionals play an important role in helping these processes happen. Equally important is the preservation of Traditional Knowledge. Recognized as the knowledge Indigenous people have accrued over millennia, and formed through their interactions with their environment, Traditional Knowledge and its preservation also fall into the world of Knowledge Management. The performance of a piece of music is the manifestation of knowledge and, in the case of Jeremy Dutcher, is a form of knowledge preservation. Traditional Knowledge’s more fluid and dynamic nature is preserved in Dutcher’s 2018 album Wolastioqiyik Lintuwakonawa, where the artist creates a conversation between technical skill and the knowledge and language of the album. In the case of this paper, Dutcher’s album serves as an example of the way Traditional Knowledge can impact and provide new tools to the information profession and world of Knowledge Management.

Method Approach

Collaborative writing (CW) involves two or more students writing a single text together. Previous studies mainly focused on students’ cognitive engagement in CW and investigated their attention to various language-related problems during task interaction. However, little CW research to date has considered that engagement in language-related discussions can manifest from three dimensions: cognitive, social, and affective. Focusing on the multidimensional characteristics of engagement, this study investigated how Russian learners’ social and affective reactions influence their focus on language use while they completed a CW task. Drawing on Svalberg’s framework of engagement with language to identify the three dimensions of engagement, I conducted a mixed-method approach towards analysing the audio-recorded collaborative dialogues by three student pairs ( n = 6), along with a qualitative analysis of their responses to a five-point Likert scale questionnaire. The analyses showed that when learners were interactive and viewed the activity as useful, they noticed many linguistic problems and elaborated on them. In contrast, when learners demonstrated social disengagement and perceived disadvantages from CW, they were likely to withdraw their attention from resolving the language issues they encountered. These findings indicate the complex and dynamic nature of task engagement. They can provide second language (L2) teachers with an in-depth understanding of how to fully engage students in instructional activities to better foster their L2 learning.

Electoral Campaigns

Very little is known in broad comparative terms about the nature and content of election campaigns. In this article, we present the first systematic and comparative assessment of the electoral campaigns of candidates having competed in elections across the world along three dimensions: negative campaigning, emotional campaigning and populist rhetoric. We do so by introducing a new dataset, based on expert judgements, that allows us to retrace the content of campaigns of 97 candidates having competed in 43 elections worldwide between 2016 and 2018. To put the importance of these three dimensions of electoral campaigns into perspective, we comparatively assess the extent to which these three dimensions are more or less likely to capture the attention of news media and to determine the electoral fate of those who rely on them. Our analyses reveal that negativity and emotionality significantly and substantially drive media coverage and electoral results: more positive and enthusiasm-based campaigns increase media attention, but so do campaigns based on personal attacks and fear appeals, especially during presidential elections and when the number of competing candidates is lower. Looking at electoral success, negativity backlashes overall, and yet personal attacks can be used successfully to increase the chances of an electoral victory. Furthermore, both appeals to enthusiasm (but not when a lot of candidates compete) and fear (especially in presidential elections) work as intended to capture the attention of the public and transform it into better electoral fortunes. We also discuss the results of a case study of the 2017 French presidential election, where we compare the campaigns of four leading candidates (Emmanuel Macron, Marine Le Pen, François Fillon and Jean-Luc Mélenchon); results of the case study offer interesting insights to understand the general trends, and beyond.

Online Learning Resources

For teachers in the 21st Century it has become critical that they develop the skills to be able to teach in a world that is being transformed by technological innovations. These skills include effectively teaching in blended learning environments with high-quality online learning resources available on the internet. Chief among the challenges faced by these teachers is that mid- and late career teachers, unlike preservice teachers, do not have adequate technology knowledge. A challenge for pre-service teachers is that they do not have the pedagogical and content knowledge to be able to effectively implement their technology knowledge in the classroom. This retrospective comparative case study was undertaken to understand reciprocal mentoring (RM) relationships that can occur between in-service teachers and pre-service teachers during implementation of a technology based lesson. The transfer of knowledge between the members of the RM dyad is described through the lens of technological pedagogical content knowledge.
