SDN-based dynamic resource management and scheduling for cognitive industrial IoT
Authors: Chandramohan S. , Senthilkumaran M.
Published: December 2021

Purpose

In recent years, it is imperative to establish the structure of manufacturing industry in the context of smart factory. Due to rising demand for exchange of information with various devices, and huge number of sensor nodes, the industrial wireless networks (IWNs) face network congestion and inefficient task scheduling. For this purpose, software-defined network (SDN) is the emerging technology for IWNs, which is integrated into cognitive industrial Internet of things for dynamic task scheduling in the context of industry 4.0.

Design/methodology/approach

In this paper, the authors present SDN based dynamic resource management and scheduling (DRMS) for effective devising of the resource utilization, scheduling, and hence successful transmission in a congested medium. Moreover, the earliest deadline first (EDF) algorithm is introduced in authors’ proposed work for the following criteria’s to reduce the congestion in the network and to optimize the packet loss.

Findings

The result shows that the proposed work improves the success ratio versus resource usage probability and number of nodes versus successful joint ratio. At last, the proposed method outperforms the existing myopic algorithms in terms of query response time, energy consumption and success ratio (packet delivery) versus number of increasing nodes, respectively.

Originality/value

The authors proposed a priority based scheduling between the devices and it is done by the EDF approach. Therefore, the proposed work reduces the network delay time and minimizes the overall energy efficiency.
Determinants of continuance intention to use mobile self-scanning applications in retail
Authors: Ferreira Andreia , Silva Graça Miranda , Dias Álvaro Lopes
Published: December 2021

Purpose

Retailers are increasingly using self-service technologies to improve customer experience and reduce costs. The purpose of this study is to identify factors that could explain the level of continuance intention of mobile self-scanning applications in retail. Based on previous theoretical streams, the present study integrates technology readiness (TR) and service quality into the technology acceptance model.

Design/methodology/approach

Using data collected through an online survey of 217 users of a mobile self-scanning application of a large supermarket chain operating in Portugal, the study uses partial least squares structural equation modeling to test the proposed hypotheses.

Findings

The results indicate that the continuance usage of the self-scanning apps is directly driven by users' satisfaction and perceived usefulness. Findings also show that TR has a positive and significant impact on ease of use and perceived usefulness. Ease of use has a positive impact on users' satisfaction and perceived usefulness but has no direct effect on the continuance intention to use the application. Perceived quality has a positive direct effect on satisfaction and a positive indirect effect on continuance intention. Finally, need for interaction has a negative effect on TR.

Originality/value

This work contributes to a better understanding of the emerging market for mobile self-scanning applications in retail applications, particularly relevant in a digital transition context.
Knowledge management and modern digital transformation of the property management industry in China
Authors: Shen Qiang , Hua Yukun , Huang Yuxing , Ebstein Richard , Yu Xiaofen , Wu Zhihua
Published: December 2021

Purpose

In the current urban and increasingly digital/information era, the service of property management towards residents is of key importance to the well-being of society, which is especially well reflected in its role during the COVID-19 pandemic in China. However, professional knowledge management (KM) has yet to be applied to the daily operation of the property management companies in this sector. The authors posit that introduction of KM concepts to property management at this time would significantly help facilitate the transition of traditional property management towards a higher and more effective value-added service model. From the perspective of KM, this study aims to offer both a theoretical and practical analysis of such a novel business model for companies in the property management industry.

Design/methodology/approach

Given the current status quo of property management, the authors integrate theories from both KM and information-digital management to qualitatively analyse the challenges and difficulties companies are facing and importantly offer practical suggestions for the centralization, digital-information platform establishment and service innovation.

Findings

Following the analysis of KM and digital-information modeling, the authors identify three main challenges facing property management services offered in the current digital society including market fragmentation, lack of digital platforms and the absence of a unitary service model. Therefore, the authors propose strategic solutions to resolve these aforementioned problems. Specifically, the authors suggest centralizing property management service, the establishment of a KM-based digital platform and the upgrading of the service model, towards offering a new impetus for the development of companies in property management.

Research limitations/implications

The authors offer essential guidelines derived from knowledge and information management and explore their implications both from a theoretical, as well as pragmatic/practical perspective that overall would support property management companies’ crucial transition from the traditional service model to a more digital-based foundation, and hence, provide a higher value-added service for the residents.

Originality/value

The current study is one of the first attempts to analyse property management services from the perspective of KM with digital transformation enabling its transition to an information-based internet of things infrastructure. The study not only offers practical guidance to the business of property management but importantly, also contributes to the theoretical underpinnings of KM especially as related to secure serviceability, well-being, security and efficiency of the residential environment by integrating people, place, process and technology.
Dynamics of the ideal self
Authors: Boyatzis Richard , Dhar Udayan
Published: December 2021

Purpose

The ideal self has had a place in management literature in recent years with reference to identity and role change. However, except for a JMD article in 2006, there has been little theorizing on the ideal self, which is often treated as a static construct. The purpose of this article is to update and refine the concept and explain the dynamic nature of the construct.

Design/methodology/approach

This conceptual paper is based on a review of the recent management and psychology literature related to the ideal self and its components.

Findings

The authors propose a dynamic theory of the emerging ideal self and delineate how its components evolve over time.

Research limitations/implications

The ideal self, or one's personal vision, is a major motivator of learning and change and the sustainability of such efforts. The time dynamic theory would encourage and guide longitudinal research using better variables and measures as well as help in conceptualizing the role of socialization, social identity and life/career stages.

Practical implications

With a better theory of the ideal self, trainers, consultants, coaches and teachers can help people update their deep sense of purpose and the sustaining driver of learning and change the ideal self. It could help people and organizations address a major determinant of engagement.

Originality/value

This theory offers a temporal understanding of how the ideal self can motivate learning and change at different life and career eras, which can help in designing future research on identity-related transitions.
Organizational creativity and sustainability-oriented innovation as drivers of sustainable development: overcoming firms' economic, environmental and social sustainability challenges
Authors: Souto Jaime E.
Published: December 2021

Purpose

Sustainable development is key to firms' competitiveness, survival, growth and profitability, although sustainability emerges as a great challenge. The aim of this study is to analyze the links between organizational creativity (which integrates sustainability orientation), sustainability-oriented innovation and the multidimensionality of firms' sustainability performance.

Design/methodology/approach

A total of 417 valid responses from manufacturing SMEs were collected through a questionnaire. PLS-SEM is the statistical technique used in the hypothesis testing.

Findings

Organizational creativity (which integrates sustainability orientation) and sustainability-oriented innovation are positively associated with economic sustainability performance, environmental sustainability performance and social sustainability performance; sustainability-oriented innovation has a partial mediation effect on the relationship between organizational creativity and economic, environmental, and social sustainability performance; and organizational creativity (which integrates sustainability orientation) has a positive effect on sustainability-oriented innovation.

Originality/value

Sustainability orientation is integrated into organizational creativity without limiting it, sustainability-oriented innovation encompasses innovation and sustainability in all its breadth without forgetting the innovation process openness, and firm's sustainability performance has a multidimensional approach. Such innovation and creativity contribute – in an interconnected way – to sustainable development, as well as overcoming sustainability challenges and firms' barriers to sustainability. Likewise, the aforementioned creativity must be implemented throughout the company, even beyond its contribution to the innovation process. Thus, the implementation of new ideas, thoughts, perspectives, views, and mental models – fruit of the described creative process – will generate new models and paths in which firms' profitability, growth and survival are related with overcoming environmental and social problems.
Performance management and hybridization of healthcare – case of the accountable care organization
Authors: Kokko Petra , Laihonen Harri
Published: December 2021

Purpose

The article seeks to explain whether and how value-based healthcare principles lead to hybridization. The public management literature has been increasingly interested in hybrid forms of governance and hybrid performance management, but empirical studies are still rare. Further, the article studies the design of performance management and accounting systems as healthcare organizations reorganize their care processes applying value-based healthcare principles.

Design/methodology/approach

This article first connects the theoretical discussions on value-based healthcare and performance management for hybrids. The conceptual understanding of performance management in hybrid healthcare uses a case study of a Finnish healthcare organization with documentary data and transcribed interviews with healthcare professionals from both the strategic and operative levels of healthcare.

Findings

The article illustrates and analyses how new policy-level objectives and principles of value-based healthcare led to hybridity in healthcare, manifest in mixed ownership of a particular care path and new forms of social and financial control. Further, the article provides empirical evidence of how increased hybridity necessitated new organizational modes and roles, new managerial tools for performance management and created a need to develop the capability to account and measure entire integrated care processes. Important enabling factors for the integration of care and hybrid performance management were commitment created in dialogue, voluntary-based trust and technology to generate factual shared information.

Practical implications

The study is informative for stakeholders, funders and managers of healthcare organizations, namely new knowledge for the discussion of hybrid governance in healthcare, including a critical account of the applicability and impact of a hybrid service model in healthcare management. Moreover, the article illustrates what needs to be reconsidered in performance management and accounting practices when reorganizing care processes according to the principles of value-based healthcare.

Originality/value

The article extends the analysis of performance management in hybrids and sheds new light on hybridization in healthcare. It also provides much-needed empirical evidence on the processes and practices of accounting and performance management after implementing a value-based healthcare strategy.
Study on the law of aging in Library and Information Science
Authors: Song Yanhui , Shen Xukang , Qiu Junping
Published: December 2021

Purpose

Aging research has traditionally been an important research topic in the field of Library and Information Science(LIS). The study of aging enables us to grasp the extent of development and the status of aging in LIS. The purpose of this paper is to explore the current law of aging in LIS and to research the impact of interdisciplinary citations on the aging of the discipline.

Design/methodology/approach

By using citation analysis methods and fitting them using the Barnett aging model, the aging law of LIS is explored with the help of aging indicators such as citing half-life and Price Index. For interdisciplinary study, the authors explore the pattern of interdisciplinary citations distribution by distinguishing LIS and non-LIS citations by journal name.

Findings

The results show that LIS is currently aging slowly and has reached a relatively mature stage. It has a high reliance on archival literature. The interdisciplinary citations distribution is broadly consistent with the overall citation distribution, and interdisciplinary citations can increase the age of applicability of the literature.

Originality/value

Based on LIS journal citation data, the paper validates the rationality of Barnett model applied in the field of literature aging research using nonlinear regression analysis, which can effectively reflect the aging law of literature and enable scholars to predict its development trend more accurately. In addition, according to the current trend of interdisciplinary citation, this paper explores the impact of interdisciplinary citations on the aging of the literature and provides a new idea for future aging research.
The mediating role of relational capital for the academic performance effect of IC: the influence of digital technologies
Authors: Arena Claudia , Catuogno Simona , Crisci Anna , Naciti Valeria
Published: December 2021

Purpose

Different mechanisms allow intellectual capital (IC) to affect performance. This paper aims to analyze the value of relations for the academic performance effect of IC and explore how the university’s reliance on digital technologies facilitates the contribution of IC to the overall academic performance.

Design/methodology/approach

The authors develop a model linking elements of IC to academic performance in the form of teaching, research and entrepreneurial activity. The model is centered on relational capital (RC) that is supposed to directly fuel performance and mediate the link between the other two IC dimensions and performance. From a methodological point of view, the authors base the empirical investigation on a sample of Italian public universities and applied structural equation modeling to test the mediation and a group comparison to disentangle the effect of universities’ digitalization.

Findings

The authors find a significant and positive effect of RC on performance. RC fully mediates the relationship between structural capital and academic performance, whereas it only partially mediates the link between human capital and academic performance. The authors also suggest that digital technologies guide the prominence of the relationship in the university’s ability to fulfill teaching, research and entrepreneurship missions through IC.

Originality/value

This study offers a representation of how the relational dimension of IC is the mean through which the stock of knowledge inside IC can be translated into entrepreneurial, education and research achievements and how digital technologies are essential for the exploitation of the performance effect of IC in the digital era.
Job satisfaction of women employees of the public sector of Afghanistan
Authors: Mehrzad Arezo , Rostan Pierre
Published: December 2021

Purpose

This paper focuses on job satisfaction of women employees in the public sector of Afghanistan and identifies factors and challenges influencing women's job satisfaction in their workplace.

Design/methodology/approach

The survey data were gathered from 92 employees working at the Ministry of Finance at different position levels.

Findings

The findings indicate that women employees highly prioritize salary increment and job promotion as their main job satisfaction factors while mentioning low salary, delay in salary payment and unsuitable workplace as the biggest challenges. Among recommendations, the research suggests to launch workshops for male employees to improve their behavior with women employees in the workplace, to promote employees based on their merit regardless of gender, to standardize salary scales, to develop a chart of female rights highlighting how they should be treated in their workplace and to support the female employees by eliminating gender discrimination and providing a secure work environment free of gender bias.

Social implications

The findings and recommendations may help public sector organizations as well as the private sector of Afghanistan to improve women employees' job satisfaction.

Originality/value

This article represents an added value for the literature which lacks references about the satisfaction of women working in the public sector of Afghanistan.
Career stages in management studies: a systematic review of scientific production from 2011 to 2020
Authors: Vilela Nágila Giovanna Silva , Casado Tania
Published: December 2021

Purpose

The purpose of this article is to present a systematic review of scientific production on career stages in the last decade (2011–2020). More specifically, it seeks to understand the methodological approaches, how career stages have been operationalized in research in the Management field, and the main results of these researches.

Design/methodology/approach

The authors searched articles about career stages on the Web of Science database published between 2011 and 2020. The final portfolio for the systematic review included 20 article based on pre-established criteria for the selection.

Findings

The results present an overview of these articles, as well as the methodological approaches used. The authors confirmed that there is no consensus on the operationalization of the career stage. Five topics associated with career stages were discussed: workers' attitudes and behaviors; training and mentoring; intentions; perception of success and work-life balance; and work values.

Originality/value

The authors found no other studies concerning the review of scientific production on career stages and divergences in the operationalization of the theme. However, considering the large number of research studies that deal with careers and their stages, it is relevant to discuss how the career stages can be operationalized and whether their operationalization is valid.
Added value for sponsors: a study of network in football 2011–2018
Authors: Erichsen Morten , Stiklestad Trond , Holum Marthe , Jakobsen Tor Georg
Published: December 2021

Purpose

This study identifies the outcomes prioritised by the sponsors of a sport, specifically football. The authors’ novel thesis is that the network collaboration between sponsors as well as with the sponsorship object (i.e. the football club) is a significant determinant of sponsor satisfaction and the likelihood of renewing the sponsorship deal. This perspective has not been adequately addressed in existing sponsorship research.

Design/methodology/approach

The authors use an original dataset to empirically analyse networks and their business value for football sponsors. Our data covers sponsors of the Norwegian football club Rosenborg Ballklub (RBK) from 2011 to 2018, which we analyse using regression models.

Findings

The results indicate that network effects are extremely important for sponsors in the RBK network. The authors’ analyses also indicate that network effects are more important than exposure.

Practical implications

When planning, sponsors must analyse their motives for being a sponsor and assess how well their network functions by exploring its cohesiveness and scope. It is also very important that the sponsorship object be aware of the value of the network and enable interaction between the sponsors.

Originality/value

This study confirms that functioning networks contribute to the satisfaction and renewal of sponsorships and can attract a growing number of sponsors for sports clubs, thus serving as an important source of income.
Children’s consumption culture development through Christmas myths: ethical implications
Authors: Kennedy Ann-Marie , Waiguny Martin K.J. , Lockie Maree Alice
Published: December 2021

Purpose

This paper seeks to explore the functions of Christmas mythemes for children’s consumption culture development. In addition, the purpose of this study is to provide an insight on the development of Central European Children into customers and how mythemes are associated with the wishing behaviour.

Design/methodology/approach

Levi-Strauss’ (1955) structural analysis was used to uncover the mythemes of the Christmas story for Austrian children. These mythemes then informed a thematic analysis of 283 Austrian children’s Christmas letters. Campbell’s (1970) functions of myths were used to reflect on the findings.

Findings

The Christmas mythemes uncovered were found to encourage materialism by linking self-enhancement (good acquirement) with self-transcendent (good behaviour) values. The role of myths to relieve the tension between the incongruent values of collective/other-oriented and materialistic values is expanded upon. Such sanctification of selfish good acquisition is aided by the mythemes related especially to the Christkind and baby Jesus. Instead, marketers should use Christmas mythemes which emphasise family and collective/other-centred values.

Originality/value

By first uncovering the “mythemes” related to Christmas, the authors contribute to the academic understanding of Christmas, going beyond origin or single myth understandings and acknowledging the multifaceted components of Christmas. The second contribution is in exploring mytheme’s representation in children’s Christmas letters and reflecting on their functions. This differs from previous literature because it looks at one of the main cultural vehicles for Christmas socialisation and its intersection with the mythemes that feed children’s consumption culture formation. Through the authors’ presentation of a conceptual framework that links mytheme functions with proximal processes using a socioecological viewpoint, the authors demonstrate the guidance of mythemes in children’s development. The third contribution is a reflection on the potential ethical implications for children’s formation of their consumer culture based on the functions of the mythemes. Furthermore, the authors add to the existing body of research by investigating a Central European context.
Topography in tropical forests enhances growth and survival differences within and among species via water availability and biotic interactions
Authors: O'Brien Michael J. , Escudero Adrián
Published: December 2021

Topography is associated with variation in soil water, biogeochemical properties and climate, which drive diversity by filtering species and promoting niche differences. However, the potential for topography to promote fitness differences and diversity among tree species and populations remains poorly tested in tropical rainforests, especially at small spatial scales in everwet climates.

We reciprocally transplanted tree seedlings between ridge and riparian sites and manipulated neighbour abundance and water availability to assess growth and survival differences both among species and between populations within species in response to changes in biotic interactions and soil water gradients associated with topographic heterogeneity.

Seedling growth rates were higher on the ridge, but probability of survival was lower on the ridge than the riparian site. Topography also altered growth and survival responses to water availability such that seedlings in the inundated soils in the riparian site had the lowest growth and survival but increased rapidly with moderate soil drying. By contrast, growth and survival on the ridge were generally unresponsive to drying, although severe drought on the ridge reinforced differences among species in growth rates and probability of survival.

The patterns of growth and survival within species did not provide evidence of local adaptation between seedlings from lowland and upslope origins. However, within species, topographic seed‐origin determined the response of seedling growth and survival to increasing neighbour abundance, indicative of divergent selective pressures between individuals growing in different topographic environments.

Combined, these results suggest that topographic heterogeneity promotes tropical forest diversity both at the species level via environmental filtering due to water availability and at the population level via functional responses to the density of neighbouring vegetation.

The active mouse rests within: Energy management among and within individuals
Authors: Abdeen Aly , Agnani Paul , Careau Vincent
Published: December 2021

The relationship between daily energy expenditure (DEE) and resting metabolic rate (RMR) provides insight into how organisms allocate energy to maintenance versus energetically expensive activities such as locomotor activity.

Three models have been devised to describe energy management: the allocation, independent and performance models, which, respectively, predict a DEE–RMR slope of b < 1, b = 1 and b > 1.

Here, we took paired repeated metabolic and behavioural measurements in 51 female white‐footed mice to (a) evaluate which energy management models apply at the among‐ and within‐individual levels and to (b) quantify the relationship between metabolic traits and two energetically expensive behaviours.

The DEE–RMR slope was different at the among‐ versus within‐individual levels, with values supporting the performance and allocation models at the among‐ and within‐individual levels, respectively. Accordingly, the relationship between voluntary wheel running and RMR was positive at the among‐individual level (r = 0.40 ± 0.21), but negative at the within‐individual level (r = −0.23 ± 0.10).

To our knowledge, this is the first study to simultaneously partition the relationship between RMR and behaviour at the among‐ versus within‐individuals levels while determining which energy management models apply at each of these levels. In doing so, we have identified a mechanism through which compensation occurs at the within‐individual level.

Precipitation temporal repackaging into fewer, larger storms delayed seasonal timing of peak photosynthesis in a semi‐arid grassland
Authors: Zhang Fangyue , Biederman Joel A. , Pierce Nathan A. , Potts Daniel L. , Devine Charles John , Hao Yanbin , Smith William K.
Published: December 2021

Against a backdrop of rising temperature, large portions of the western United States are experiencing fewer, larger and less frequent precipitation events. How such temporal ‘repackaging’ of precipitation alters the magnitude and timing of seasonal maximum gross primary productivity (GPPmax) remains unknown. Addressing this knowledge gap is critical, since changes to GPPmax magnitude and timing can impact a range of ecosystem services and management decisions.

Here we used a field‐based precipitation manipulation experiment in a semi‐arid mixed annual/perennial bunchgrass ecosystem with mean annual precipitation ~384 mm to investigate how temporal repackaging of a fixed total seasonal precipitation amount impacts seasonal GPPmax and its timing.

We found that temporal repackaging of precipitation profoundly influenced the seasonal timing of GPPmax. Many/small precipitation events advanced the seasonal timing of GPPmax by ~13 days in comparison with climatic normal precipitation. Conversely, few/large events led to deeper soil water infiltration, which delayed the timing of GPPmax by up to 16 days in comparison with climatic normal precipitation, and altered end‐of‐season community composition by increasing the diversity of shallow‐rooted annual plants. While GPPmax magnitude did not differ across precipitation treatments, it was positively correlated with the abundance and biomass of deeper‐rooted perennial bunchgrasses. The sensitivity of plant growth, biomass accumulation and plant life histories to the timing and magnitude of precipitation events and the resulting temporal patterns of soil moisture regulated ecosystem responses to altered precipitation patterns.

Our results highlight the sensitivity of semi‐arid grassland ecosystem to the temporal repackaging of precipitation. We find that already‐observed and model‐forecasted shifts toward few/large precipitation events could drive significant delays in the timing of peak productivity for this ecosystem. Adaptive land management frameworks should consider these findings since shifts in peak ecosystem productivity would have major implications for multiple land user communities. Additional research is needed to better understand the role of climate, community composition and soil properties in mediating variability in the seasonal timing of maximum ecosystem productivity.

S.
Published: December 2021

Ecosystem restoration is a global priority, currently promoted by several ambitious commitments. Most of the research to guide restoration practices was so far put on the recovery of above‐ground functions and services, although soil health is increasingly recognized as a fundamental condition to restoration success. Soil restoration is particularly needed in mining areas, in which the surface soil layers are removed and the left over, highly deprived substrate does not support vegetation recovery.

Here, we evaluated the potential of active restoration to recover soil attributes after bauxite mining in the Brazil's Atlantic Forest. We specifically studied how physical, chemical and microbiological soil attributes down to 40 cm depth respond to restoration (i.e. topsoil spreading and tree planting) by comparing newly mined areas, areas undergoing restoration for ~7 years and conserved forests. We further explored the associations between microbiological and physico‐chemical soil attributes.

Restoration interventions resulted in a 10‐fold increase in the soil organic matter content compared to mined areas, as well as in the recovery of P content. Restoration was also shown to be associated with the recovery of the activity and diversity of soil bacterial communities, reaching similar levels to those observed in conserved forest. Restored and conserved forests were characterized by a higher proportion of Acidobacteria, Planctomycetes and Verrucomicrobia. All bacterial attributes were correlated with soil physical attributes, except for microporosity, and with organic matter and cation exchange capacity.

Within a few years, restoration allowed recovering crucial physical, chemical and microbiological soil attributes, reaching levels comparable to those found in conserved forests.

Synthesis and applications. We demonstrate that intensive management can result in the fast restoration of tropical forest soils after mining, at least at small scales. Our results stress the need to consider soil recovery both as a driver and a measure of ecosystem restoration success, and support the development of more holistic monitoring protocols to be used during the United Nations Decade on Ecosystem Restoration.
THE ZOONOTIC CITY: Urban Political Ecology and the Pandemic Imaginary
Authors: Gandy Matthew
Published: December 2021

In the context of the Covid‐19 pandemic this article takes a longer view of the evolving relationship between urbanization and the range of zoonotic diseases that have spread from animals to humans. I suggest that the existing interpretation of epidemiological transitions remains overly Eurocentric and requires a more nuanced conception of global environmental history. Similarly, the conceptualization of urban space within these teleological schemas has relied on a narrow range of examples and has failed to fully engage with networked dimensions to urbanization. At an analytical level I consider the potential for extending the conceptual framework offered by urban political ecology to take greater account of the epidemiological dimensions to contemporary urbanization and its associated pandemic imaginary. I examine how contemporary health threats intersect with complex patterns of environmental change, including the destruction of biodiversity (and trade in live animals), the co‐evolutionary dynamics of viruses and other pathogens, and wider dimensions to the global technosphere, including food production, infrastructure networks, and the shifting topographies of peri‐ or ex‐urban contact zones.
The current situation and the cultural background of psychological type theory in China
Authors: Cai Chenghou
Published: December 2021

As analytical psychology in China develops, especially with the China Society for Analytical Psychology approved for membership in the International Association for Analytical Psychology (IAAP), many Chinese, who are already familiar with MBTI®‐based personality testing in corporations, are interested in learning more about Jungian theory and practice with regard to psychological types. The author, a Chinese psychologist, emphasizes current problems standing in the way of this development, such as the common opinion that MBTI is equal to psychological types. He reports his recent research that highlights the present understanding of psychological types within China. Noting that Jung combined two attitudes with four functions to form eight function‐attitudes of consciousness, the author explores the possible connection between Jung’s eightfold system and the eight trigrams that organize the wisdom that the I Ching brings to emergent situations requiring exceptionally conscious decision‐making. He compares I Ching translator Richard Wilhelm’s naming and description of these eight Gua with Jungian analyst John Beebe’s descriptions of the eight function‐attitudes and finds striking parallels. This amplification sheds light on the archetypal nature of psychological consciousness as well upon the typology of it that Jung advanced.
Type development in childhood and beyond
Authors: Murphy Elizabeth
Published: December 2021

This article defines and explains type development across the lifespan and summarizes what other researchers have presented as a reference. A timeline for development is identified, and ways to differentiate development of a function from the development of other personality characteristics are described. Type development is about the dispersion of energy from an unconscious level to a managed conscious level. This development occurs in a spiral pattern, so development of each function occurs repeatedly but at higher levels of use and understanding each time. Although the dominant function develops most because of its innate drive to be the lead, each function can develop throughout the lifespan. The relative energy associated with each function always exists. When the energy is in the unconscious, it drives behavioural responses, but these are not within the individual’s control. The ideal is to develop the conscious awareness of each of the functions so each can be consciously used as needed to match a situation. Because development of the functions is essential, this article examines potential interferences with development and then offers some suggestions for ways to promote developmental opportunities.

Authors: Nata Naowanit , Bunpeth Wasin , Tasanavipas Pamila , Varothai Narittaya , Supasyndh Ouppatham , Satirapoj Bancha
Published: December 2021

ABTRACT

Background

Hyperkalemia is common among end‐stage renal disease (ESRD) patients, and consequently contributes to an increased risk of cardiac arrhythmia. Senna glycoside may decrease colonic transit time and potassium colonic reabsorption.

Methods

Patients on hemodialysis were randomized to receive either oral senna glycoside (n = 37) or control (n = 36) for 8 weeks. The primary outcomes were predialysis serum potassium and prevalence of hyperkalemia.

Results

At the end of the study, significantly reduced serum potassium concentrations were observed in the senna glycoside compared with the control (−0.32 [95%CI −0.43, −0.04] vs. −0.02 [95%CI −0.12, 0.05] mEq/L, p < 0.001, respectively). The prevalence of hyperkalemia during the study occurred at 13.8% in the control and 5.4% in the senna glycoside (p = 0.309). No serious adverse events were observed.

Conclusion

Among patients with ESRD on hemodialysis, senna glycoside significantly decreases serum potassium level. Senna glycoside is a safe and possibly effective alternative treatment for hyperkalemia in ESRD.
Implementing the 2020–2025 Dietary Guidelines for Americans: Recommendations for a path forward
Authors: Sanders Lisa M. , Allen Jonathan C. , Blankenship Jeanne , Decker Eric A. , Christ‐Erwin Mary , Hentges Eric J. , Jones Julie M. , Mohamedshah Farida Y. , Ohlhorst Sarah D. , Ruff John , Wegner Jill
Published: December 2021

The Dietary Guidelines for Americans (DGA) provide science‐based recommendations for healthy dietary patterns to promote health and reduce risk of chronic diseases. Yet, since their inception in 1980 and updates every 5 years, Americans fall short of meeting dietary recommendations and diet‐related chronic diseases continue to be a public health concern. In May of 2021, the Institute of Food Technologists and the Department of Food Science at the University of Massachusetts, Amherst, convened a diverse group of thought leaders in health, nutrition, and food science to identify opportunities and approaches to improve consumer adoption of the DGA recommendations. The invited leaders collaborated in roundtable discussions to develop recommendations and strategies to promote adoption of the DGA recommendations after hearing sessions on the latest consumer trends, advances in food science and technology, and effective communications approaches. Participants agreed that changes in consumer behaviors and heightened interest in health due to the novel coronavirus pandemic have created an opportune time to engage consumers about healthy eating. Communications must be simple, tailored to the consumer, and delivered by influencer(s)/spokesperson(s) who are credible sources and share personal values. Innovations in food science and technology have enabled improvements in the safety, health, acceptability, affordability, and availability of foods but opportunities to provide more options to enhance consumption of desired food groups, such as fruits, vegetables, and whole grains, remain. Moving Americans toward healthier dietary patterns aligned with DGA recommendations will require collaborations within the food sector and beyond to achieve broad scale amplification and investment.
Empirical properties of diversion ratios
Authors: Conlon Christopher , Mortimer Julie Holland
Published: December 2021

The diversion ratio for products and is the fraction of consumers who leave product after a price increase and switch to product . Theoretically, it is expressed as the ratio of demand derivatives from a multi‐product firm's Bertrand‐Nash first‐order condition. In practice, diversion ratios are also measured from second‐choice data or customer‐switching surveys. We establish a LATE interpretation of diversion ratios, and show how diversion ratios are obtained from different interventions (price, quality, or assortment changes) and how those measures relate to one another and to underlying properties of demand.

Data on children that had undergone a drug provocation test for a suspected antibiotic allergy were compiled retrospectively for the period from 2007–2018. The median age at the first provocation was 2.25 years (1.5–5.7). Standardised questionnaires, the children's parents had answered before the provocation, were used to evaluate the originally suspected allergic reaction, previous health, atopic diseases and family history.

Results

Ninety‐two (6.4%) of the 1440 children showed a possible mild allergic reaction. Sixty‐four of the 92 children underwent a second drug provocation test 1–2 years later. At that time, only eleven developed a positive‐ or a possible‐delayed reaction.

Conclusion

An immediate moderate or severe allergic reaction was excluded in all cases of suspected antibiotic allergy in this study. Our study indicates that an oral drug provocation test is safe. It may be appropriate to wait for 6 months or more after the initial event of ADR before these tests are performed. A second oral provocation 1–2 years after the first one shows that ADRs are outgrown in most children.
Frustration in technology‐rich learning environments: A scale for assessing student frustration with e‐textbooks

Published: December 2021

e‐Textbooks and e‐learning technologies have become ubiquitous in college and university courses as faculty seek out ways to provide more engaging, flexible and customizable learning opportunities for students. However, the same technologies that support learning can serve as a source of frustration. Research on frustration with technology is limited, especially in educational settings. This study examined student frustration with e‐textbooks and the factors contributing to the frustration within undergraduate general biology courses through the development of an E‐Text Frustration scale (ETFS). Exploratory factor analysis of the ETFS revealed a three‐factor structure that provides quantified support for frustration with (1) e‐textbook interactions on the screen, (2) problems with technology and (3) e‐text curriculum integration. This structure was supported by a confirmatory factor analysis. The construct validity of the scale was established using a correlation analysis that revealed significant relationships among the three e‐text frustration measures, cognitive load and motivation variables. Furthermore, the measurement invariance analyses indicated that the scale measures the same construct in the same way in males and females. Overall, the study findings suggest that the ETFS is a useful instrument with high reliability and validity evidence that can be used by researchers and practitioners. Implications for future research on frustration in technology‐rich learning environments are discussed.

Practitioner notes

What is already known about this topic

Prolonged student frustration can be harmful to learning.

Educational technology may introduce an additional layer of factors that contribute to end‐user frustration with technology.

Research on frustration with educational technology is scarce.

What this paper adds

We developed and validated a scale for assessing students' frustration with e‐textbooks.

TheE‐Text Frustrationscale includes three factors: frustration with technology, e‐text screen interactions and e‐text curriculum.

The three factors correlated with students' e‐text cognitive load and motivation to learn.

Implications for practice and/or policy

The identified factors represent barriers to students' successful learning with e‐textbooks.

Educators can reduce student frustration by aligning the curriculum with e‐text materials.

Student sources of frustration with technology should be studied systematically to reduce frustration in technology‐rich learning environments.
Cross‐modal impression updating: Dynamic impression updating from face to voice and the other way around

Published: December 2021

Research has shown that faces and voices shape impression formation. Most studies have examined either the impact of faces and voices in isolation or the relative contribution of each source when presented simultaneously. However, only a few studies have questioned whether and how impressions formed via one source can be updated due to incremental information gathered from the alternative source. Yet, cross‐modal impression updating is key to shed light on person perception. Thus, we tested whether positive and negative face‐ and voice‐based impressions could be updated by inconsistent cross‐modal information. In Experiment 1 (N = 130), we tested whether face‐based impressions could be updated by (in)consistent voices. In Experiment 2 (N = 262), we compared face‐to‐voice and voice‐to‐face impression updating. In Experiment 3 (N = 242), we favoured a more direct comparison of the two types of stimuli (i.e., the co‐occurrence of both cue types when the new information is revealed). Results showed that voices have the greatest updating impact and that the updating effect of faces was halved when voices co‐occurred for a second time. We discussed these results as evidence of the dynamical evolution of cross‐modal impressions.
