Epidemic modeling as a means to reimagine health education and policy post-COVID
Authors: Racine Elise E. , Bryson Joanna J. 
Published: November 2021

PurposeAs illustrated by coronavirus disease 2019 (COVID-19), epidemic models are powerful health policy tools critical for disease prevention and control, i.e. if they are fit for purpose. How do people ensure this is the case and where does health education fit in?Design/methodology/approachThis research takes a multidisciplinary approach combining qualitative secondary and primary data from a literature review, interviews and surveys. The former spans academic literature, grey literature and course curriculum, while the latter two involve discussions with various modeling stakeholders (educators, academics, students, modeling experts and policymakers) both within and outside the field of epidemiology.FindingsMore established approaches (compartmental models) appear to be favored over emerging techniques, like agent-based models. This study delves into how formal and informal education opportunities may be driving this preference. Drawing from other fields, the authors consider how this can be addressed.Practical implicationsThis study offers concrete recommendations (course design routed in active learning pedagogies) as to how health education and, by extension, policy can be reimagined post-COVID to make better use of the full range of epidemic modeling methods available.Originality/valueThere is a lack of research exploring how these methods are taught and how this instruction influences which methods are employed. To fill this gap, this research uniquely engages with modeling stakeholders and bridges disciplinary silos to build complimentary knowledge.

Authors: Thuy Nguyen Thi Minh , Thi Nguyen Dinh 
Published: November 2021

PurposeThe paper aims to research the applications of topological geometry to the architectural concept design process and their combination with the modern digital technology to find novel architectural spaces and forms which are dynamic, easily adaptable to the context and surroundings.Design/methodology/approachThe article uses the method of studying the existing literature on topological geometry and architectural design theory including design thinking, architectural design methods and architectural compositions to analyze and compare them with architectural practices and suggest new topological design tools and methods. Moreover, the paper tests the proposals with a number of preliminary design research experiments. In addition, graphic design software, parametric design, building information modeling (BIM) and digital development trends in architecture were explored and experienced to reveal the application potential of topological design thinking and methods in the trend of architectural digitization.FindingsThe paper has analyzed, synthesized and systematized the basic theories of topological geometry in order to clarify their applications in the architectural concept design process. On that basis, the paper proposes a novel topological design thinking and method for finding rich diversified architectural ideas and forms based on original invariant design constraints. Finally, the paper clarifies the combination as well as the mutual, motivating relationship between topological geometry and modern digital technologies when applied to architectural design.Originality/valueThe research contributes a novel design thinking and method based on topological geometry combined with modern digital technology to the architectural design theory. It will be a valuable tool capable of suggesting architects how to think and innovate in architecture in the era of industrial revolution 4.0.
Schematizing vulnerability perceptions and understanding of drought-prone Gamo lowland communities: an evidence from Southwest Ethiopia
Authors: Tora Thomas Toma , Degaga Degefa Tolossa , Utallo Abera Uncha 
Published: November 2021

Purpose
The conceptual root of vulnerability dates back to the 1970s in the social science spheres. Vulnerability is a multi-dimensional and determinant precondition for disaster occurrence. The Gamo lowlands are exposed to a wide range of vulnerabilities. Therefore, this study aims to schematize community perceptions and understanding of vulnerability in drought-affected rural Gamo lowlands.

Design/methodology/approach
A community-based cross-sectional survey design and the mixed-methods research approach were executed. A four-staged multistage sampling was used to identify the respondent households. Into the four study sites, sample households were allocated proportionally by the lottery method. The survey data were gathered from 285 lowland households. The structured survey questionnaire, key informant interview, focus group discussion, and field observations, and transect walks were the tools used to collect the primary data. Data were analyzed deploying both qualitative and quantitative techniques. The Likert scale is used to analyze households’ vulnerability perceptions in which the item analysis approach was used for detailed analysis of the Likert-type items.

Findings
Locally, people perceive and understand vulnerability as exposure to drought hazard, rainfall inconsistency, the prevalence of human and animal diseases, livelihood insecurity, food shortfalls, poor income, lack of access to market, landholding and livestock ownership which are schematized by vulnerability perception pathways that delineate its extent. The findings also showed that the Gamo lowland inhabitants are unequally vulnerable as 96.5% of the studied households stated the differential idiosyncrasy of vulnerability. Old-aged, small-sized and female-headed households with no supportive force were found to be more vulnerable.

Practical implications
For better resilience, enhancing communities’ perceptions and understanding of vulnerability via continuous awareness creation by all the concerned stakeholders is recommended as the majority was lowly educated. It also yields input for policy debates and decision-making in the drought-prone lowland setup for building a resilient community.

Originality/value
To the best of the authors’ knowledge, this is an original work pursued by using a household survey with empirical data sourced from drought-prone rural lowland communities.
Creating customer value in the sharing economy: an investigation of Airbnb users and their tripographic characteristics
Authors: So Kevin Kam Fung , Kim Hyunsu , Min Somang 
Published: November 2021

PurposeThis paper aims to investigate the roles of different types of customer value in influencing in customer evaluations of Airbnb. In particular, this study empirically tests the roles of four value dimensions in shaping existing Airbnb users’ attitudes and future behavioral intentions along with the effects of tripographic characteristics on users’ post-purchase evaluative judgments.Design/methodology/approachThis study adopted a multi-study approach to test the hypotheses. In Study 1, theoretical relationships between constructs were proposed and empirically analyzed; and in Study 2, a different sample was used to validate the hypothesized model and enhance the external validity of the findings. After completing both studies, the two samples were combined to test for the moderating effects of several key tripographic factors among Airbnb users.FindingsThis study found that price value, emotional value, quality value and social value were critical factors exerting differential effects on customers’ evaluations of Airbnb. Further analysis of group differences revealed that Airbnb customers’ value perceptions differed significantly depending on the length of stay, group size and number of previous trips. The number of previous trips also had a significant moderating effect on the relationship between social value and attitudes.Research limitations/implicationsThe findings of this study contribute to the literature on Airbnb by presenting a comprehensive assessment of the differential effects of value components in evaluating Airbnb experiences with the consideration of tripographic characteristics. While supporting the importance of emotional, social, quality and price value to Airbnb guests, the results also show that Airbnb seems to appeal particularly to visitors who stay longer, travel with large groups and have used the platform several times in the past.Originality/valueThe findings of this study provide important insight into which customer values contribute to users’ attitudes and consequent favorable behaviors. More importantly, this study emphasized the importance of understanding the moderating effects of tripographic characteristics in the relationships between customer values and existing users’ evaluative judgment of Airbnb experiences.
What is rogue marketing? An exploration of how hard seltzer sparked a social media phenomenon
Authors: Norris Cortney L. , Taylor D. Christopher , Taylor Jr. Scott 
Published: November 2021

Purpose
This study aims to introduce, explicate, offer a framework and provide future research directions for a phenomenon herein named rogue marketing. Rogue marketing is explored vis-à-vis a phenomenon that occurred over the summer of 2019 with a new product category, hard seltzers. It is proposed that rogue marketing occurs when an unaffiliated individual creates and posts an informal message about a brand on social media that becomes viral. Although the post is not funded or endorsed by the company that owns the brand, reaching viral status results in free and unexpected advertising (positive or negative).

Design/methodology/approach
Rogue marketing is first explored through a comparative analysis with company produced advertisements. Then, the company’s response to rogue marketing is gauged through both qualitative and quantitative data. The sample of 210 respondents was recruited from students enrolled in college hospitality courses and through posts made on social media.

Findings
Rogue marketing is found to be somewhat more compelling than company produced advertisements and those who found the rogue marketing message more compelling had stronger sentiments regarding the company’s response.

Research limitations/implications
This exploratory study of rogue marketing provides a conceptualization and starting framework for future research concerning this phenomenon.

Originality/value
Rogue marketing is a new phenomenon and is distinct from influencer marketing and viral marketing in its characteristics. Additionally, the company’s response to rogue marketing messages may influence behavioral outcomes.

The response of majority employee-owned firms during the pandemic compared to other firms
Authors: Blasi Joseph , Kruse Douglas , Weltmann Dan 
Published: November 2021

PurposeThe purpose of this study is to understand how majority employee-owned firms responded to the pandemic compared to firms that were not majority employee-owned. The Employee Ownership Foundation partnered with Rutgers University and the SSRS survey firm to survey ESOP and non-ESOP firms about their responses to the COVID-19 pandemic. A key purpose of the survey was to estimate firm-level changes in employment from mid-January to August (current employment figures were adjusted to August 5 using BLS industry employment trends). The survey also looked at other forms of adjustment and responses to the pandemic as reviewed below. The focus in this study is on the differences between firms that are majority owned by ESOPs and those that are not.Design/methodology/approachThe survey included 247 executives from ESOP Association member companies and 500 executives from an SSRS business panel constructed to be representative of US companies with 50 or more employees. The survey started on August 5 and ended on September 23, 2020.Findings(1) Majority ESOP firms had employment declines from January to August that were on average only one-fourth as large as for other firms. The difference is maintained when controlling for industry membership. (2) Majority ESOP firms were more likely to be declared “essential,” but the lower employment cutbacks among majority ESOP firms remain among essential and non-essential businesses. As essential businesses, majority ESOP firms were more likely receive Paycheck Protection Program or other government pandemic assistance, but both assistance recipients and non-recipients had lower employment cutbacks among majority ESOP firms. (3) The extent of employment cutbacks was higher for non-managers than for managers, but the manager/non-manager gap was higher among other firms than among majority ESOP firms.Research limitations/implicationsThis study supports empirical findings done previously.Practical implicationsThis study suggests to non-EO firms what they can do.Social implicationsThis study suggests strengths of EO firms.Originality/valueA very original and one-of-a-kind dataset.
Performing openness: how the interplay between knowledge sharing and digital infrastructure creates multiple accountabilities
Authors: Träskman Tomas Ivan , Skoog Matti 
Published: November 2021

PurposeThe present study aims to address the emergence of platform-organized open innovation (OI). The research has the two main aims: the first is to increase the understanding of the performance of OI by investigating how the achievements of OI are measured in situated practices from a performative and strategic knowledge management (SKM) orientation. The methodological disadvantages of not pre-given case selection are partially counterbalanced by the second aim of the research, which is to extend existing SKM theory and examine how platforms create knowledge as they include actors and digital devices, thereby potentially redistributing relations of accountability.Design/methodology/approachBuilding on performativity theory, the paper studies how the achievements and knowledge created in OI are managed and evaluated in practice. The case description draws on different sources from a spiral case study, as openness is performed by platform, firm, crowd and innovation intermediaries.FindingsThe paper illustrates how a strategy of digitally enabled openness brings its own issues as platforms enable knowledge sharing and perform a redistribution of accountability. In the heterarchies studied through this research endeavor, managers and their team members were accountable not only to multiple units, or teams, across the organization, but also to the crowd. The case material demonstrates that the ecology of devices and their performative struggles create lateral accountability.Research limitations/implicationsWhile recent streams of research suggest that the context of OI (i.e. distributed sources of knowledge for innovation) shifts the unit of analysis of organization design from the individual firm to networks of actors organized on platforms, the authors find that the focal firm still remains a key conceptual parameter in SKM research, which, in turn, makes it difficult to capture the suggested radicality of OI.Practical implicationsThe authors show, that in practice, the firm has to take into account the performance of the external crowd and at times put resources into its training and education. In heterarchy, distributed authority is assumed to be facilitated through lateral accountability, whereby the traditional principles of vertical authority no longer hold, but rather, managers and their team members can be accountable to multiple units, or teams, across the organization.Originality/valueThe paper develops a performative theory of openness. OI is a model, strategy and socio-material practice whereby digital designs create an ecology of devices that can enact all kinds of openness. Ultimately, the current paper proposes that SKM and OI theory need to consider how platforms perform relations of accountability beyond the boundaries of the single organization.
Impact of different aging conditions on the IMC layer growth and shear strength of Ni-modified MWCNTs reinforced Sn-Ag-Cu composite solder
Authors: Zhai Xinmeng , Chen Yue , Li Yuefeng 
Published: November 2021

Purpose
The purpose of this paper is to develop a new composite solder to improve the reliability of composite solder joints. Nano-particles modified multi-walled carbon nanotubes (Ni-MWCNTs) can indeed improve the microstructure of composite solder joints and improve the reliability of solder joints. Although many people have conducted in-depth research on the composite solder of Ni-MWCNTs. However, no one has studied the performance of Ni-MWCNTs composite solder under different aging conditions. In this article, Ni-MWCNTs was added to Sn-Ag-Cu (SAC) solder, and the physical properties of composite solder, the microstructure and mechanical properties were evaluated.

Design/methodology/approach
In this study, the effect of different aging conditions on the intermetallic compound (IMC) layer growth and shear strength of Ni-modified MWCNTs reinforced SAC composite solder was studied. Compared with SAC307 solder alloy, the influence of Ni-MWCNTs with different contents (0, 0.1 and 0.2 Wt.%) on composite solder was examined. To study the aging characteristics of composite solder joints, the solder joints were aged at 80°C, 120°C and 150°C.

Findings
The experimental results show that the content of Ni-MWCNTs affects the morphology and growth of the IMC layer at the interface. The microhardness of the solder increases and the wetting angle decreases. After aging at moderate (120°C) and high temperature (150°C), the morphology of the Cu6Sn5 IMC layer changed from scallop to lamellar and the grain size became coarser. The following two different phase compositions were observed in the solder joints with Ni-MWCNTs reinforcement: Cu3Sn and (Cu, Ni)6Sn5. The fracture surface of the solder joints all appeared ductile dents, and the size of the pits increased significantly with the increase of the aging temperature. Through growth kinetic analysis, Ni-modified MWCNTs in composite solder joints can effectively inhibit the diffusion of atoms in solder joints. In short, when the addition amount of Ni-MWCNTs is 0.1 Wt.%, the solder joints exhibit the best wettability and the highest shear strength.

Originality/value
In this study, the effects of aging conditions on the growth and shear strength of the IMC layer of Ni modified MWCNTs reinforced SAC307 composite solder were studied. The effects of Ni MWCNTs with different contents (0, 0.1 and 0.2 Wt.%) on the composite solder were examined.
A conceptual framework for a systemic understanding of barriers during lean implementation
Authors: Puram Praveen , Sony Michael , Antony Jiju , Gurumurthy Anand 
Published: November 2021

PurposeMultiple organisations which have attempted to implement lean production/manufacturing/thinking have failed to achieve significant benefits. Practitioners and researchers have identified the barriers that hinder successful implementation. This study first consolidates such lean implementation barriers that are common across all industry sectors. Further, a systemic understanding of lean barriers is attempted by determining causal relationships between barriers and their relative causal strength.Design/methodology/approachBarriers to lean implementation were first identified from extant literature and categorised into broad barrier groups. These barrier groups were classified into four categories as specified by Liker's 4P model of lean–philosophy, people and partnership, processes and problem-solving. Additionally, interrelations between barriers, both within and among these four categories were determined.FindingsThe barriers classified under philosophy were the most critical as it affects the barriers in other groups. Similarly, barriers such as lack of leadership and top management commitment, lack of resources, shortage of lean consultants and trainers, lack of systemic understanding of lean and the need for its implementation, lack of lean expertise and training were found to be the most critical causal barriers.Research limitations/implicationsHighly critical barriers in terms of causality should be addressed with high priority, as effective measures against them may eliminate or reduce the impact of other barriers.Originality/valueThis study addresses the confusion regarding the high number of lean barriers in extant literature by providing a systemic understanding of the same. By exploring the interrelations among barriers, the most important causal barriers and barrier types (4Ps) are identified, the knowledge of which could improve lean implementation success. This is a novel attempt in the domain of lean.

SummaryUnderstanding biogeographical patterns and underlying processes of belowground community assembly is crucial for predicting soil functions and their responses to global environmental change. However, little is known about potential differences of belowground community assembly among bacteria, fungi, protists and soil animals, particularly for alpine ecosystems. Based on the combination of large‐scale field sampling, high‐throughput marker‐gene sequencing and multiple statistical analyses, we explored patterns and drivers of belowground community assembly in alpine grasslands on the Tibetan Plateau. Our results revealed that the distance–decay rates varied among trophic levels, with organisms of higher trophic level having weaker distance–decay pattern. The spatial and environmental variables explained limited variations of belowground communities. By contrast, the stochastic processes, mainly consisting of dispersal limitation and drift, played a primary role in regulating belowground community assembly. Moreover, the relative importance of stochastic processes varied among trophic levels, with the role of dispersal limitation weakening whereas that of drift enhancing in the order of bacteria, fungi, protists and soil animals. These findings advance our understanding of patterns and mechanisms driving belowground community assembly in alpine ecosystems and provide a reference basis for predicting the dynamics of ecosystem functions under changing environment.
