Associations between social support and verbal memory: 14-year follow-up of the English Longitudinal Study of Ageing cohort
Authors: Scholes Shaun , Liao Jing 
Published: July 2020

AbstractObjectiveExamine the longitudinal associations between social support and verbal memory among community-dwelling adults.ParticipantsIn the English Longitudinal Study of Ageing, 10,837 participants aged 50-89 years were assessed at wave 1 (baseline: 2002-03) and followed-up over 14-years to wave 8 (2016-17).MethodsVerbal memory was assessed at each wave by tests of immediate and delayed word-recall. Positive and negative social support were measured across four types of relationship (spouse/partner, children, friends, extended family). Linear mixed effects modelling examined the between-person (PM) and within-person (PM) associations between social support and verbal memory. Interaction terms were fitted to estimate differences in the rate of change in verbal memory by social support.ResultsWhen we summed scores across all relationships (global social support), higher-than-average (PM) positive social support was associated with higher baseline verbal memory (βPM = 0.015; 95% Confidence Interval (CI): 0.008, 0.025; p < 0.001) and with slower decline (βPM-by-time = 0.003; 95% CI: 0.001, 0.005; p = 0.003). Longitudinal associations were gender- and source-specific. Among men, slower decline in verbal memory was associated with higher positive social support from children (βPM-by-time = 0.009; 95% CI: 0.002, 0.016; p = 0.011) and with lower negative social support from spouse/partner (βPM-by- time = −0.016; 95% CI: −0.031, 0.000; p = 0.045) and from friends (βPM-by-time = −0.021; 95% CI: −0.039, −0.004; p = 0.018). Among women, higher positive social support from extended family was associated with slower decline in verbal memory (βPM-by-time = 0.008; 95% CI: 0.000, 0.015; p = 0.049).ConclusionsBetween-person differences in social support were modestly associated with differential decline in verbal memory. Our findings can inform future research studies and intervention strategies designed to maximise the potential role of supportive relationships in promoting healthy cognitive ageing.

AbstractThe detection of viruses in sewage is a method of environmental surveillance, which allows evaluating the circulation of different viruses in a community. This study presents the first results of sewage surveillance to detect the circulation of SARS-CoV-2 virus in Santiago, Chile. Using ultracentrifugation associated with RT-qPCR, we detected SARS-CoV-2 in untreated and treated wastewater samples obtained two treatment plants, which together process around 85% of the wastewater from the city. This is the first report of detection of SARS-CoV-2 in sewage in Chile and indicates that wastewater surveillance could be a sensitive tool useful as a predictive marker of the circulation of the virus in a population and therefore, be used as an early warning tool.

Published: July 2020

PurposeCoffee in capsules consumers’ behaviour depends not only on the products’ attributes, but also the consequences perceived by them and the alignment with their values. This paper aims to investigate the impacts of the Attributes of coffees in capsules on the consequences perceived by consumers concerning their consumption and the effects of these Consequences on consumers’ Values.Design/methodology/approachThis study developed a scale for assessing the perception of consumers of coffee in capsules about Attributes, Consequences and Values (A-C-V) regarding its consumption. A link to this survey’s electronic questionnaire was posted on the social networks Facebook and Peabirus. This research sample is for convenience and accessibility and has 213 consumers of coffee in capsules. Structural Equation Modelling (SEM) was the statistical method used for data analysis.FindingsAttributes have two sub-dimensions (Own attributes and Functional attributes), while Consequences have three sub-dimensions (Handling Benefits, Rational Benefits, Convenience Benefits) and Values have just one dimension. Also, SEM has shown a statistically significant positive relationship between A-C-V perceived by consumers of coffee in capsules. These results confirm the hypotheses developed based on the Means-End Chain Theory (MEC).Originality/valueAs academic contributions, this paper develops a structural model that quantitatively demonstrates the impacts of Attributes perceived by consumers of coffee in capsules on the Consequences of consumption and its effects on their Values. The present survey is the first in the literature that uses structural models contemplating A-C-V. As managerial contributions, this survey provides relevant information to the decision-making of several stakeholders of the chain of coffee in capsules.
Humanistic paradigm in leadership practice – a case study of a Confucian entrepreneur
Authors: Chou Wan-Ju , Cheng Bor-Shiuan 
Published: July 2020

PurposeWhile current management theory is largely based on economic assumptions, there is evidence to suggest capitalism is at a crossroads. Humanistic management is accordingly proposed as an alternative new paradigm. The present study follows this approach in considering Confucianism as a humanistic practice. The purpose of this study is to explore humanistic leadership displayed by a Confucian leader and how he/she presents humanistic concern in corporate management to pursue the common good.Design/methodology/approachThis study adopted a structured–pragmatic–situational approach to conduct a case study and collected data from three sources: semi-structured interviews, consultant observations and archival data.FindingsThe findings reveal that a Confucian leader takes all stakeholders' interests into account while engaging in corporate management and displays humanistic behaviors toward the stakeholders that are in line with five Confucian virtues. The leader cultivates the employees as Confucian humanistic agents. These employees accordingly act as bridges to transmit the humanistic spirit to their customers and other industries in the same market. To initiate an industry change to achieve collective welfare, a Confucian leader must first influence his/her primary stakeholders. The primary stakeholders next collectively influence the secondary stakeholders (i.e. the industry). Consequently, the overall goal of the common good is ultimately sustained.Originality/valueThis study identifies valuable practical implications for humanistic practices in corporate management from a Confucian perspective. In addition, this study takes a significant academic step forward by illuminating the humanistic paradigm.
What should be centralized and what should not: that is the question within a school of business context
Authors: Rivas Luz Maria , Correa Stefania 
Published: July 2020

Learning outcomes
The case’s learning objectives to work on can vary according to the topic selected by the teacher. This case has been put forward with a particular interest in corporate strategy issues, specifically, on the joint management of businesses (in this case, academic programs). Therefore, students are expected to be able to understand the managerial dilemma on centralization and decentralization; recognize the peculiarities of a shared services center (SSC); and decide on which services to centralize in an SSC.

Case overview/synopsis
Centralizing or not centralizing is a frequent managerial dilemma. This is a challenge faced not only by business managers but also by corporate level areas responsible for jointly managing various businesses. Resources and capabilities allocation is an essential process for strategy execution, specifically in corporate strategy that must answer the question: How to jointly manage businesses? Sharing services is a collaborative strategy which aims to increase efficiency by centralizing some processes related to this joint business management. Mario, Dean of the Escuela de Administración in Medellín, Colombia, intends to optimize the school resource allocation processes so that there is more equitable support between the different academic programs. For this, he has thought of creating an SSC as it is a practice that he has seen in prominent companies in the city. His idea is to start operating the SSC in early 2018; however, the particular character of a management school leads him to ask himself: What to centralize and what not to centralize?

Complexity academic level
This case of decision (Ellet, 2007; Sánchez et al., 2013) can be used to promote student learning of strategy courses both at advanced undergraduate levels and in graduate programs. Likewise, it can be used in workshops with executives and administrative personnel of companies that face the centralize–decentralize dilemma. These types of topics are the subject of study by both corporate strategy theorists who address the question of how to jointly manage business (Menz et al., 2015; Michael Porter, 1987) and consultants (Deloitte, 2012). It is desirable, although not mandatory, that students have some knowledge or experience in strategic issues and challenges associated with the administration of companies made up of various businesses (multi-business firms).

Teaching as invasion: emotions, boundaries and entanglements
Authors: Stutelberg Erin B. 
Published: July 2020

Purpose
This paper aims to engage nine women English teachers in exploring their personal memories centered around the perception of their raced, classed and gendered teacher bodies, and led them to conceptualize teaching as invasion.

Design/methodology/approach
The process of collective memory work (CMW), a qualitative feminist research method, was used to structure collaborative sessions for the nine women English teachers. In these sessions, the group took up the CMW process as the memories were written, read, analyzed and theorized together.

Findings
The analyses of two memories from our group's work builds understanding of how the use of new materialism and a conceptualization of emotions as social, collective and agentic, can expand the understanding of the teacher bodies and disrupt normalizing narratives of teaching and learning. The post-humanist concept of intra-action leads one to better understand the boundaries in the teacher – student relationships that is built/invaded, and to see the ways materials, humans, emotions and discourses are entangled in the teaching encounters.

Originality/value
This study demonstrates how sustained and collective research methodologies like CMW can open space for teachers to more fully explore their identities, encounters and relationships. Further, unpacking everyday classroom moments (through the framework of literacy-as-event) can yield deep and critical understanding of how bodies, emotions and non-human objects all become entangled when teaching becomes an act of invasion.
Accountants' IT responsibilities and competencies from a student perspective
Authors: Junger da Silva Raphael , Tommasetti Roberto , Zaidan Gomes Monica , da Silva Macedo Marcelo Alvaro 
Published: July 2020

PurposeResearch question is about the perception of stricto sensu undergraduate and graduate accounting students, from the Metropolitan Region of Rio de Janeiro (Brazil) of the accountants' responsibilities and competencies required to them in assisting IT/IS strategy definition and implementation.Design/methodology/approachThis is a descriptive research, using a qualitative paper-and-pencil approach. Designed based on United Nations Accounting Model Curriculum, a questionnaire was self-applied to 361 accounting students of eight higher education institutions (HEIs) in Rio de Janeiro, whose responses are quantitatively analysed.FindingsAccounting students strongly agree on the need to acquire strategic skills that enable them to assist organizations in IT/IS issues but are quite divided about the related accountants' responsibilities, underestimating their future role in this respect.Research limitations/implicationsAlthough quantitatively adequate, the sample is non-probabilistic and, thus, results cannot be generalized. The authors expect that this paper can encourage HEIs to engage the path of multidisciplinary education and rethink their silo-based pedagogical models which have to prepare students for their forthcoming professional challenges, by introducing interdisciplinary courses, soft skills disciplines and work-integrated learning activities.Practical implicationsFindings can be useful for teachers and coordinators of the IT/IS area in accounting courses, stimulating brainstorming on the accountant's role in assisting organizations in IT/IS strategies and practices implementation. The study has relevant implications for educators through the identification and analysis of difficulties faced by students.Originality/valueThis study contributes to the research base of accountants' strategic role since the responsibility awareness identified gap can be elaborated for stimulating the discussion about the centrality of the accountant in IT processes within organizations.

Authors: Wardiningsih Wiah , Troynikov Olga 
Published: July 2020

PurposeThis study aimed to evaluate the performance attributes relevant to thermal wear comfort of the commercially available hip protective pads and materials intended for impact protection that can be used for the hip protective pad.Design/methodology/approachThe performance attributes relevant to thermal wear comfort (i.e. dry thermal resistance and evaporative resistance) of the pads were tested using MTNW Integrated Sweating Guarded Hotplate (iSGHP).FindingsIt was found that: the pad with more porous structure has more advantages in terms of evaporative resistance; the permeability index will be higher on the pad with an opening such as a segmented pad; the permeability index will be lower on the thicker and larger pad. The pocket fabric with open structure will have lower dry thermal resistance and evaporative resistance.Originality/valueThe study results showed that the properties of the utilised materials influenced thermal comfort performance. These results could be useful for designing and engineering hip protective garments.
Computer-aided diabetic retinopathy diagnostic model using optimal thresholding merged with neural network
Authors: Jadhav Ambaji S. , Patil Pushpa B. , Biradar Sunil 
Published: July 2020

PurposeDiabetic retinopathy (DR) is a central root of blindness all over the world. Though DR is tough to diagnose in starting stages, and the detection procedure might be time-consuming even for qualified experts. Nowadays, intelligent disease detection techniques are extremely acceptable for progress analysis and recognition of various diseases. Therefore, a computer-aided diagnosis scheme based on intelligent learning approaches is intended to propose for diagnosing DR effectively using a benchmark dataset.Design/methodology/approachThe proposed DR diagnostic procedure involves four main steps: (1) image pre-processing, (2) blood vessel segmentation, (3) feature extraction, and (4) classification. Initially, the retinal fundus image is taken for pre-processing with the help of Contrast Limited Adaptive Histogram Equalization (CLAHE) and average filter. In the next step, the blood vessel segmentation is carried out using a segmentation process with optimized gray-level thresholding. Once the blood vessels are extracted, feature extraction is done, using Local Binary Pattern (LBP), Texture Energy Measurement (TEM based on Laws of Texture Energy), and two entropy computations – Shanon's entropy, and Kapur's entropy. These collected features are subjected to a classifier called Neural Network (NN) with an optimized training algorithm. Both the gray-level thresholding and NN is enhanced by the Modified Levy Updated-Dragonfly Algorithm (MLU-DA), which operates to maximize the segmentation accuracy and to reduce the error difference between the predicted and actual outcomes of the NN. Finally, this classification error can correctly prove the efficiency of the proposed DR detection model.FindingsThe overall accuracy of the proposed MLU-DA was 16.6% superior to conventional classifiers, and the precision of the developed MLU-DA was 22% better than LM-NN, 16.6% better than PSO-NN, GWO-NN, and DA-NN. Finally, it is concluded that the implemented MLU-DA outperformed state-of-the-art algorithms in detecting DR.Originality/valueThis paper adopts the latest optimization algorithm called MLU-DA-Neural Network with optimal gray-level thresholding for detecting diabetic retinopathy disease. This is the first work utilizes MLU-DA-based Neural Network for computer-aided Diabetic Retinopathy diagnosis.
Spectator satisfaction model for mass participant sport events: antecedents and consequences
Authors: Duan Yanling , Liu Bing 
Published: July 2020

PurposeThe purpose of this paper is to propose and examine an integrated model of spectator satisfaction in mass participant sport events.Design/methodology/approachThe Wuhan marathon, held in the middle of China, was selected serve for the study to examine the antecedents and consequences of spectator satisfaction at mass participant sport events. Data were collected from 956 spectators of the event on the day of the race. Structural equation modeling was used to examine the research model proposed by this study.FindingsStructural equation modeling results indicate the following. First, the event image and perceived social impact of the event are important predictive factors of spectator satisfaction. Second, spectator satisfaction is positively associated with behavioral intentions toward the event and the sponsors' product. Third, spectator satisfaction plays a significant mediating role between the antecedents and consequences; specifically, compared to perceived social impacts of the event, event image has greater indirect effects on both event-related behavioral intentions and event sponsors' products.Originality/valueUntil now, there has not been an integrated research study on the sport spectator satisfaction model in the context of mass participant sport events. This paper thus extends the understanding of the spectator satisfaction in the context of mass participant sport events, and the findings provide valuable implications for holding cities and event organizers of mass participant sport events in emerging countries.
“Empathy machine”: how virtual reality affects human rights attitudes
Authors: Bujić Mila , Salminen Mikko , Macey Joseph , Hamari Juho 
Published: July 2020

PurposeThis study aims to investigate how media content consumed through immersive technology may evoke changes in human rights attitudes. It has been proposed that our inability to empathize with others could be overcome by stepping into another's shoes. “Immersive journalism” has been postulated as being able to place us into the shoes of those whose feelings and experiences are distant to us. While virtual reality (VR) and 360-degree news videos have become widely available, it remains unclear how the consumption of content through immersive journalism affects users' attitudes.Design/methodology/approachUtilizing a between-subject laboratory-controlled experiment (N = 87) this study examined participant scores on the Human Rights Questionnaire before and after consuming 360-degree video immersive journalism content via VR (n = 31), 2D (n = 29), and Article (n = 27) formats. Collected data were analysed using statistical inference.FindingsResults indicate that immersive journalism can elicit a positive attitudinal change in users, unlike an Article, with mobile VR having a more prominent effect than a 2D screen. Furthermore, this change is more strongly affected by users' higher Involvement in the content.Originality/valueThese findings are relevant for grasping the distinct effects novel and recently popularized technologies and media have on attitudinal change, as well as inform the current debate on the value of VR as “empathy machines”.
