Population dynamics with threshold effects give rise to a diverse family of Allee effects
Authors: Fadai Nabil T. , Simpson Matthew J. 
Published: April 2020

AbstractThe Allee effect describes populations that deviate from logistic growth models and arises in applications including ecology and cell biology. A common justification for incorporating Allee effects into population models is that the population in question has altered growth mechanisms at some critical density, often referred to as athreshold effect. Despite the ubiquitous nature of threshold effects arising in various biological applications, the explicit link between local threshold effects and global Allee effects has not been considered. In this work, we examine a continuum population model that incorporates threshold effects in the local growth mechanisms. We show that this model gives rise to a diverse family of Allee effects and we provide a comprehensive analysis of which choices of local growth mechanisms give rise to specific Allee effects. Calibrating this model to a recent set of experimental data describing the growth of a population of cancer cells provides an interpretation of the threshold population density and growth mechanisms associated with the population.

Authors: Liu Kai-di , Yang Duo-Gui , Yang Guoliang , Zhou Zhi-Tian 
Published: April 2020

Purpose
This paper aims to investigate the situation and evolution of sustainability performance in China.

Design/methodology/approach
This paper adopts the global Malmquist-Luenberger (GML) productivity index based on data envelopment analysis and Tobit regression for analysis.

Findings
The results indicate the following: China’s sustainability performance has been improving since 2005 and is closely related to the national development strategy and supportive policy; regional gaps in sustainability are a prominent problem represented by the fact that South Central China is becoming a sustainability collapse zone; interprovincial heterogeneity is evident with the varying development speed and conditions; and the level of sustainability performance has a significantly positive correlation with the urbanization rate, investment completed in the treatment of industrial pollution, government appropriation for education and per capita area of paved roads, but it has a negative correlation with the possession of private vehicles.

Originality/value
As an application, this study assessing the GML productivity index of 30 provinces in China from 2005 to 2015 and analyse the sustainability performance on three regional levels (i.e. country level, regional level and provincial level). Tobit regression is also applied to recognize the factors related to the GML index with the results taken as references for policy suggestions. The results have implications for a comprehensive understanding of China's sustainability performance and policymaking in this field.
Past behaviour, financial literacy and investment decision-making process of individual investors
Authors: Raut Rajdeep Kumar 
Published: April 2020

PurposeThis study aims to explore the importance of past behaviour and financial literacy in the investment decision-making of individual investors and examines the validity of the theory of planned behaviour in this context.Design/methodology/approachThe study used a self-administered questionnaire and adopted the convenience sampling technique followed by a snowball sampling method for the survey to collect data from the individual investors covering the four distinct states of India. Collected data were analysed on AMOS 20.0 using two-step structural equation modelling (SEM).FindingsResults indicated a significant effect of all the predictive variables. Past behaviour showed no significant direct impact on investor's intention; however, it had an indirect significant relationship while mediated by the attitude of investors. The multiple squared correlation (R2) showed that the final model could explain 36% of the variance in investors' intention towards stock investment which signified a successful implementation of the TPB model along with external variables added to it. Moreover, Indian investors were found to be highly influenced, primarily, by social pressure which could be curbed through financial literacy.Practical implicationsA significant importance of subjective norms was found on stock market participation which could be a strategic theme for the government and the policymakers to educate investors through their opinion leaders for increasing their participation. Moreover, by doing so investors could control their behaviour and take rational decisions.Originality/valueThis study extended the understandings of investor's decision-making behaviour using TPB by incorporating the two external variables viz., Financial literacy and past behaviour. The addition of past behaviour is perhaps the novelty of this article since such examination has not been conducted empirically especially in the case of developing countries like India.

Published: April 2020

PurposeIn highlighting brain wave responses of emotional processing, the purpose of this study is to investigate (1) the effect of sport participation involvement on affective reaction in viewing photos; and (2) the association between affective reaction and behavioral intentions.Design/methodology/approachUsing lateralized event-related potentials, the authors examined how brain wave reactions are different based on different sport involvement between two groups where one group had varsity sport experience while the other expressed that they were not fans of the sport.FindingsResults indicated a significant difference in lateralization between groups. Brain responses were greater in the high involvement group and positively correlated with the intention to attend future games.Originality/valueThe findings in this study elucidate the linkage between one's history of sport involvement and affective brain wave responses. Implications from neurophysiological evidence provide means to further dissect the multifaceted construct of involvement in the field of sport marketing.
Australian office workers' response to sedentary behaviour messaging
Authors: Chapman Janine , Fletcher Chloe , Corsini Nadia , de Cure Georgina 
Published: April 2020

PurposeTo provide insight into how office workers respond to sedentary health messages following the introduction of the Australian Physical Activity and Sedentary Behaviour Guidelines.Design/methodology/approachVia online survey, office workers (n = 185) reported awareness of the Guidelines and sedentary risk, availability of workplace movement-based initiatives, and measures of sitting time, intention, self-efficacy, and perceived barriers to sedentary behaviour. Participants then viewed one of two brief messages (“Occupational Risk” or “Strategies”); indicated their message receptivity and provided written recommendations. Participants who consented to a second survey (n = 126) completed sitting time and psychological measures again after four weeks.FindingsOnly 23% were aware of the Guidelines; willingness to follow public health guidance was mixed. Barriers to adoption were apparent for existing initiatives. Message receptivity was high for both messages. For the follow-up survey, an improvement in psychological variables and workplace sitting was reported in those who viewed the Occupational Risk compared to the Strategies message. Qualitative analysis revealed lack of organisational support and called for increased employer responsibility.Research limitations/implicationsAs participants self-selected into the study, the sample may be more health-conscious than the typical office worker.Practical implicationsWorkers are receptive to brief messages and the Occupational Risk message showed promise in promoting change. However, sedentary exposure is viewed as an organisational-level issue. A “whole of workplace” approach is needed with co-designed strategies tailored to the culture and working practices within the organisation.Originality/valueThis study offers insight into avenues for improving the management of prolonged sitting and workplace sedentary behaviour.
Structural network embeddedness and firm incremental innovation capability: the moderating role of technology cluster
Authors: Shi Xiaoxiao , Lu Lu , Zhang Wei , Zhang Qingpu 
Published: April 2020

Purpose
This paper aims to propose the following questions: How do structural network embeddedness influence firms’ incremental innovation capability? Does technology cluster moderate the relationships between them?

Design/methodology/approach
In this empirical research, the authors collected a sample of patent data in the smartphone industry over the period of 2000-2018. Then, the authors examined the direct roles of structural network embeddedness on firms’ incremental innovation capability and the moderating role of technology cluster by using ordinary linear squares regression.

Findings
The empirical results show that occupying the central position positively affects firms’ incremental innovation capability, and clustering strengthens this linear relationship. Furthermore, bridging structural holes has an inverted U-shaped effect on incremental innovation capability, and clustering positively moderated this nonlinear relationship, while bridging ties across different clusters plays a negative moderation role in this relationship.

Originality/value
This empirical research provides new insights into whether and how firms can grasp the benefits of structural network embeddedness to conduct incremental innovations and the moderation effects of technology cluster contingencies. It further contributes to the structural network embeddedness–incremental innovation capability issue by extending its research context to the smartphone industry.
Ideological leadership in public schools
Authors: Eyal Ori , Schwartz Talya R. , Berkovich Izhak 
Published: April 2020

PurposeThis study aims to explore the conception and construct of ideological leadership (IL) as it relates to public organizations, such as public schools, and to validate a tool for its measurement in this setting.Design/methodology/approachData was collected from 633 teachers working at 69 randomly-sampled Israeli public schools. In each school, an average of nine (SD = 2) randomly-sampled teachers completed questionnaires that measure IL, transformational leadership, organizational commitment, leader-member exchange and motivational factors. The data underwent validity and hypotheses tests.FindingsThe hypothesized presence of the personalized and socialized IL orientations among public-school principals has been confirmed. Only personalized IL predicted teachers' outcomes above and beyond transformational leadership, affecting measures of organizational commitment, leader-member exchange and controlled motivation.Originality/valueNew evidence supports the validity of this proposed measurement tool. New evidence also suggests that although ideology has been known to be a factor of charismatic leadership, IL in close public-school settings accentuates practices of control, rather than proselytizing coherent worldviews to teachers. This, in turn, may have a deleterious influence on work outcomes and outweigh the possible benefits of IL. Accordingly, it is suggested that school leaders should critically consider the desirability of embracing ideological zeal as part of their leadership tools.
What drives organizations to switch to cloud ERP systems? The impacts of enablers and inhibitors
Authors: Chang Yu-Wei 
Published: April 2020

PurposeSwitching to public cloud enterprise resource planning (ERP) systems not only provides financial and functional benefits to organizations, but also results in sunk costs of incumbent systems and uncertainty costs of cloud systems. The purpose of this study is to investigate the enablers and inhibitors concerning switching to cloud ERP systems at the organizational level.Design/methodology/approachData were collected from 212 top managers and owners of the enterprises in Taiwan, and 10 hypotheses were examined using structural equation modeling.FindingsTechnological (system quality), organizational (financial advantage), and environmental contexts (industry pressure) are found to be the antecedents of switching benefits. Perceived risk of cloud ERP systems and satisfaction with and breadth of use of incumbent ERP systems are found to be the predictors of switching costs. Switching benefits positively affect switching intention, but switching costs negatively affect switching intention.Research limitations/implicationsThis study develops a theoretical model grounded in a set of theoretical foundations, including two-factor theory, technology-organization-environment (TOE) framework, information systems (IS) success model, and expectation confirmation theory (ECT). Two-factor theory is used to characterize switching benefits and costs that affect switching intention. Technological factors come from IS success model, and the factors affecting benefits are organized based on TOE framework. Sunk costs of incumbent ERP systems are developed based on ECT.Originality/valueDifferent from previous studies on cloud computing adoption, this study provides insights into switching intention to cloud computing. The study also proposes an integrated model grounded in multiple perspectives to explain organizations' decisions to switch to cloud ERP systems. These findings help cloud service providers better understand how to promote cloud ERP adoption from technical, organizational, and environmental perspectives.
Determinants of mandatory disclosure compliance in Swedish municipalities
Authors: Donatella Pierre 
Published: April 2020

PurposeThe purpose of this article is to examine whether, and if so, to what extent, noncoercive isomorphism determines mandatory disclosure compliance at a later stage of an accounting reform.Design/methodology/approachThe analysis of compliance is based on data from 289 Swedish municipalities for 2016, which is nearly two decades after the initial legal reform in which mandatory requirements were imposed by the Swedish government in an effort to harmonize financial reporting practice. Following the standard approach in the literature, an unweighted compliance index was used as dependent variable. Proxies for municipal accounting networks and involvement in professional government accounting associations were used to explain individual municipalities' levels of compliance.FindingsDifferences in individual municipalities' levels of compliance were strongly related to the financial reporting practice of other municipalities in their accounting network. These results suggest that normative and mimetic isomorphic pressure stemming from these local networks, where accounting departments continually meet and share experiences, is a very potent force. In contrast, isomorphic pressure stemming from involvement in activities offered by professional government accounting associations is generally not a potent force at this stage.Practical implicationsIn settings where municipal accounting networks exist, it may be effective to stimulate de facto harmonization by directing information, education and other efforts toward the professional environment in which these networks operate.Originality/valueUnlike prior literature, the data in this study are from a later stage of a public sector accounting reform.

Published: April 2020

PurposeThe purpose of this study is to assess the drivers, practices and policies for implementing sustainable construction in Nigeria. This is with a view towards increasing the rate of implementation and diffusion of sustainable construction practice, so that more Nigerians can benefit from its environmental, social and economic dividends.Design/methodology/approachThis study adopted a qualitative research design with the use of face-to-face oral interviews. Interviewees were selected using a purposive sampling technique. Data from the interview were analysed using thematic analysis. Descriptive statistics of frequencies, percentages and rankings were also used to present the data and complement the thematic analysis.FindingsThe study identified five major drivers of sustainable construction: clients' demand, international pressure, corporate social responsibility, competitiveness and cost-effectiveness. The common sustainable practices adopted by the interviewees are compliance with health and safety regulation, waste management, energy efficiency and material reuse. The most appropriate policies for implementing sustainable construction as suggested by the interviewees were government regulations, provision of tax relief and subsidies and public awareness. A combination of regulatory policies, market-based policies and voluntary participation of stakeholders will enhance the attainment of sustainability transformations in the construction industryOriginality/valueThe study is based on the findings of construction participants who have practical experience with sustainable construction in Nigeria. The study also provides empirical evidences which could guide the design and implementation of policies that will further promote the diffusion of sustainable construction in Nigeria
The effect of Bi addition on the electrical and microstructural properties of SAC405 soldered structure
Authors: Soares Delfim , Sarmento Manuel , Barros Daniel , Peixoto Helder , Figueiredo Hugo , Alves Ricardo , Delgado Isabel , Teixeira José C. , Cerqueira Fátima 
Published: April 2020

Purpose
This study aims to investigate the effect of bismuth addition (up to 30 Wt%) on the microstructure and electrical conductivity of a commercial lead-free alloy (SAC405) near the solder/substrate soldered joint. The system under study is referred in this work as (SAC405 + xBi)/Cu, as Cu is the selected substrate in which the solder was casted. The electrical resistivity of this system was investigated, considering Bi addition effect on the local microstructure and chemical composition gradients within that zone.

Design/methodology/approach
Solder joints between Cu substrate and SAC405 alloy with different levels of Bi were produced. The electrical conductivity along the obtained solder/substrate interface was measured by four-point probe method. The microstructure and chemical compositions were evaluated by scanning electron microscopy/energy dispersive spectroscopy analysis.

Findings
Two different electrical resistivity zones were identified within the solder interface copper substrate/solder alloy. At the first zone (from intermetallic compound [IMC] until approximately 100 μm) the increase of the electrical resistivity is gradual from the substrate to the solder side. This is because of the copper substrate diffusion, which established a chemical composition gradient near the IMC layer. At the second zone, electrical resistivity becomes much higher and is mainly dependent on the Bi content of the solder alloy. In both identified zones, electrical resistivity is affected by its microstructure, which is dependent on Cu and Bi content and solidification characteristics.

Originality/value
A detailed characterization of the solder/substrate zone, in terms of electrical conductivity, was done with the definition of two variation zones. With this knowledge, a better definition of processing parameters and in-service soldered electronic devices behavior can be achieved.
How off-season tourism promotion affects seasonal destinations? A multi-stakeholder perspective in Tibet
Authors: Senyao Sang , Wei He , Ma Ni 
Published: April 2020

Purpose
Taking Tibet as a case study, this paper aims to develop an in-depth understanding of the influence that off-season tourism promotion (OTP) has on seasonal destinations from a multi-stakeholder perspective.

Design/methodology/approach
A qualitative research method was designed using participatory observation, in-depth interviews and focus group interviews in Tibet from March 2018 to February 2019.

Findings
The results revealed the different effects of OTP on destinations from a multi-stakeholder perspective. Residents report place change as a perceived threat from off-season tourists. Additionally, the irregular nature of seasonal employment can lead to service provider–related failures. While traditional seasonal tourists viewed OTP promotions as the destruction of place identity, promotion-motivated tourists presented a lesser degree of place loyalty. The prospect of off-season tourism has also led to concerns among scholars regarding deteriorating environmental sustainability.

Practical implications
This paper can help destination managers and policymakers re-assess the effects of seasonality and off-season tourism policies.

Originality/value
This paper discusses the phenomenon of seasonality from a multi-stakeholder perspective. The study explores residents’ perception of OTP-related place change, the causes of seasonal employment and how the market segments in off-season tourism, all of which complement existing research. Lastly, using a mixed data collection and analysis method, the study provides a feasible approach to analyze tourism phenomena.
Dutch care environments for people with dementia: impressions from the perspectives of an architect and a gerontologist
Authors: Shannon Kay , Jurgenhake Birgit 
Published: April 2020

Purpose
The purpose of this paper is to discuss Dutch innovative care environments for older people, including those living with dementia, from the perspectives or an architect and a social gerontologist.

Design/methodology/approach
The authors visited three care environments for older people, each offering an innovative approach to living housing older people, including people with dementia. The settings are discussed from two disciplinary perspectives, facilitating an understanding of the influence of the built environment on daily life for residents.

Findings
The three facilities were all architecturally varied and resembled “real” homes to varying degrees. Additionally, each entrance offered a different welcome to the external community, ranging from full accessibility to a closed and fortified appearance. Within each facility, the built environment afforded residents opportunities to participate in valued activities, including interacting with members of the wider community.

Originality/value
The inclusion of two disciplinary perspectives offers a richer discussion of the physical and social aspects of the care environments that would be offered by one perspective alone.
