A hybrid-electric unmanned aerial vehicle (HE-UAV) model has been developed to address the problem of low endurance of a small electric UAV. Electric-powered UAVs are not capable of achieving a high range and endurance due to the low energy density of its batteries. Alternatively, conventional UAVs (cUAVs) using fuel with an internal combustion engine (ICE) produces more noise and thermal signatures which is undesirable, especially if the air vehicle is required to patrol at low altitudes and remain undetected by ground patrols. This paper aims to investigate the impact of implementing hybrid propulsion technology to improve on the endurance of the UAV (based on a 13.6 kg UAV).

A HE-UAV model is developed to analyze the fuel consumption of the UAV for given mission profiles which were then compared to a cUAV. Although, this UAV size was used as reference case study, it can potentially be used to analyze the fuel consumption of any fixed wing UAV of similar take-off weight. The model was developed in a Matlab-Simulink environment using Simulink built-in functionalities, including all the subsystem of the hybrid powertrain. That is, the ICE, electric motor, battery, DC-DC converter, fuel system and propeller system as well as the aerodynamic system of the UAV. In addition, a ruled-based supervisory controlled strategy was implemented to characterize the split between the two propulsive components (ICE and electric motor) during the UAV mission. Finally, an electrification scheme was implemented to account for the hybridization of the UAV during certain stages of flight. The electrification scheme was then varied by changing the time duration of the UAV during certain stages of flight.

Based on simulation, it was observed a HE-UAV could achieve a fuel saving of 33% compared to the cUAV. A validation study showed a predicted improved fuel consumption of 9.5% for the Aerosonde UAV.

The novelty of this work comes with the implementation of a rule-based supervisory controller to characterize the split between the two propulsive components during the UAV mission. Also, the model was created by considering steady flight during cruise, but not during the climb and descend segment of the mission.

This article reports on a study around a further education, blended-learning program aiming to establish globally active professional learning networks (PLNs). The questions guiding the research were: (1) What levers and barriers to establishing viable networks are identified by its members? (2) What – if any – indications of knowledge transfer within the networks can be identified?

The networking aspect of the study program was analyzed using semi-structured interviews with its recent participants and graduates (n = 22), with the objective of gaining insights into elements that supported the creation and maintenance of a global, student-centered network and community in the program. Additionally, a document analysis of the master theses of all participants since the start of the program (n = 96) was undertaken to look for indications of knowledge transfers from one cultural and/or geographical setting to another.

Blending online exchanges with face-to-face exchanges was seen as helpful in establishing a sustainable network. Additionally, having a low-barrier communication platform where it was socially acceptable to not only communicate about professional but also informal matters was described by virtually all participants as a promoting exchange and cohesion. Furthermore, about a fifth of all analyzed master theses contained indications of knowledge transfer, with instances of incorporating models or concepts from other contexts being the most prominent occurrence.

The findings offer insights into establishing sustainable blended-learning networks. They elaborate on key elements that supported and hindered the creation and viability of such networks. Furthermore, they highlight the importance of formal but also informal spaces for exchange.

This study aims to explore whether English-language learners (ELLs) who have struggled to pass a high school exit exam (HSEE) self-report that they are able to self-regulate their learning. It is of interest to find out whether, in addition to limited English proficiency, these students are struggling to exert control over their learning.

Using semi-structured interviews, the study sought the perspectives of eight ELLs who had repeatedly failed their state-mandated HSEE. Interviews were transcribed using a modified grounded theory approach, and thought units were coded with a focus on the following elements of SRL: self-understanding, goal directedness, flexibility and strategy use.

Results indicated that all interviewees demonstrated a greater, more specific awareness of their academic weaknesses than their strengths. Half the interviewees demonstrated an awareness of how they learned. Similarly, half of them verbalized that they approached learning flexibly. None of the interviewees reported using evidence-based strategies. However, all interviewees were goal-oriented.

This research approach may limit the external validity of the results. The richness of the data may also be limited because interviews were conducted in English.

The findings from this study have implications for educating ELLs in an era of standards-based education and helping them pass HSEEs.

These results also have implications for advancing social justice through informed educational policy.

This paper fills a gap in the literature by extending the theory of SRL, which is associated with academic success in diverse students, to ELLs, a rapidly growing demographic in US public schools that is struggling to achieve academic success.

Misconduct and deviance amongst police officers are substantial issues in policing around the world. This study aims to propose a prediction model for serious police misconduct by variation of the theory of planned behaviour.

Using two data sets, one quantitative and one qualitative, provided by an Australian policing agency, a random forest analysis and a qualitative content analysis was performed. Results were used to inform and extend the framework of the theory of planned behaviour. The traditional and extended theory of planned behaviour models were then tested for predictive utility.

Each model demonstrated noteworthy predictive power, however, the extended model performed particularly well. Prior instances of minor misconduct amongst officers appeared important in this rate of prediction, suggesting that remediation of problematic behaviour was a substantial issue amongst misconduct prone officers.

It is an important implication for policing agencies that prior misconduct was predictive of further misconduct. A robust complaint investigation and remediation process are pivotal to anticipating, remediating and limiting police misconduct, however, early intervention models should not be viewed as the panacea for police misconduct.

This research constitutes the first behavioural model for police misconduct produced in Australia. This research seeks to contribute to the field of behavioural prediction amongst deviant police officers, and offer an alternative methodology for understanding these behaviours.

Criminology both as a field of study and as a practice draws on a broad range of disciplines from the social, behavioural, human, natural and medical sciences. However, over recent times, the natural and medical sciences have been dismissed, overlooked and even ridiculed, largely since the rise of critical criminology and related contemporary conflict and social harm approaches from the 1960s onwards. This has led to a chasm emerging between the study of criminology and the practice of criminology such as within a policing context. This paper aims to provide a review of an emerging forensic biological method, that of neuroscience, within a criminological context, to illustrate the importance of criminology embracing and reawakening its natural and medical science roots.

The paper draws on a conceptual design to realign criminology with the full range of disciplines used to inform its theory and application.

Through illustrating the role of forensic neuroscience, the paper reawakens the scientific method and inquiry of criminology reflecting the importance of the discipline being, and remaining, multi- and trans-disciplinary in nature. The paper, while reflecting on the limitations of scientific method and inquiry, outlines the strengths this approach to criminology engenders, promoting and delivering a scientific-based research agenda that aims to support industry partners in the prevention, disruption and reduction of crime, disorder and threats to public security.

Firstly, it is important for criminology as a field of study to (re)engage with its scientific method and inquiry. Secondly, criminology, by engaging in robust scientific method and inquiry, has a significant contribution to make to professional practice and the work of industry professionals. Thirdly, while there are limitations to such scientific method and inquiry, it should not lead to this component of criminology being discarded. Fourthly, there is a need for contemporary research in the area of scientific method and inquiry and its application to criminological contexts, including that of police practice. Finally, by engaging in scientific method and inquiry that is evidence based, a chasm between the field of study and the practice associated with criminology can be addressed.

This paper addresses the gap between criminology as a field of study and as a practice by reengaging with scientific method and inquiry, illustrating the need and value of criminology being and remaining multi- and trans-disciplinary, ensuring professions underpinned by criminology are supported in their practice.

The purpose of this paper is to examine how upstream social marketing can benefit from using social media commentary to identify cognitive biases. Using reactions to leading media/news publications/articles related to climate and energy policy in Australia, this paper aims to understand underlying community cognitive biases and their reasonings.

Social listening was used to gather community commentary about climate and energy policy in Australia. This allowed the coding of natural language data to determine underlying cognitive biases inherent in the community. In all, 2,700 Facebook comments were collected from 27 news articles dated between January 2018 and March 2020 using exportcomments.com. Team coding was used to ensure consistency in interpretation.

Nine key cognitive bias were noted, including, pessimism, just-world, confirmation, optimum, curse of knowledge, Dunning–Kruger, self-serving, concision and converge biases. Additionally, the authors report on the interactive nature of these biases. Right-leaning audiences are perceived to be willfully uninformed and motivated by self-interest; centric audiences want solutions based on common-sense for the common good; and left-leaning supporters of progressive climate change policy are typically pessimistic about the future of climate and energy policy in Australia. Impacts of powerful media organization shaping biases are also explored.

Through a greater understanding of the types of cognitive biases, policy-makers are able to better design and execute influential upstream social marketing campaigns.

The study demonstrates that observing cognitive biases through social listening can assist upstream social marketing understand community biases and underlying reasonings towards climate and energy policy.

Sponsorship is a major contributor to income in the South African sports arena, and is a critical component allowing sports unions to remain financially viable and sustainable. Sports sponsoring companies, however, have long questioned the financial returns generated from these ventures. The purpose of this paper is to understand whether financial returns of companies with sports sponsorship in South Africa are significantly different to those without. This research was conducted on Johannesburg Stock Exchange (JSE) listed companies that sponsored sport consistently between 2000 and 2015 for a period of two years. A quantitative methodology was employed whereby share price, revenue and earnings growth were analysed, comparing firms that did not adopt strategies involving sports sponsorships to those that did.

A quantitative methodology was employed, whereby share price, revenue and earnings growth were analysed, comparing firms that did not adopt strategies involving sports sponsorships to those that did. South Africa is an emerging market and a member of the BRICS Forum ranked 14th in the sport sponsorship market globally (Sport Marketing Frontiers, 2011), becoming increasingly dominant in the global sports industry (Goldman, 2011). The population consisted of JSE-listed Main Board and alternative exchange companies that participated in any form of consistent sports sponsorship in the given time frame: 2000-2015, where the company’s share price, revenue and earnings per share (EPS) data for the period were available from the INET BFA database. The JSE is ranked 17th in terms of market capitalisation (over $1 trillion) in the world, being the largest stock exchange on the African continent with over $30bn being traded on average monthly. Multiple journals today publish research done on the JSE, for example the International Journal of Sports Marketing and Sponsorship, Investment Analysts Journal and the South African Journal of Accounting Research. This stock exchange is 125 years old and has over 400 listed companies of which 358 are domestic (Kruger et al., 2014).

Results show that companies involved in sports sponsorship during the period analysed did not experience enhanced share price or revenue growth in excess of those companies not involved in sports sponsorship. As a whole, sports sponsoring companies did however experience greater income growth (EPS) than those companies not involved in sports sponsorship. Enhanced revenue growth was found in the consumer services sector, indicating that sport sponsorship in this sector drives brand image and recall resulting in enhanced revenues. These results though indicate that a multitude of differing objectives may exist for companies engaging with sports sponsorship, with increased sales not the singular objective. In general it is concluded that sports sponsorship is considered to achieve a broad spectrum of outcomes that are likely to contribute to increased profitability.

The relatively small size of 40 firms on the JSE in the South African sports sponsorship market is a limitation for this research. The purely quantitative approach limited the ability to gain the required level of insight into those sectors with small samples, which a qualitative study would reveal. SABMiller as example could not be analysed against its sector peers, given that it is one of the most prominent and consistent sports sponsors in South Africa across all major sporting codes. The telecommunications sector was represented entirely by companies that were involved in sports sponsorship and, hence, no in-depth comparison could be conducted within this sector. Vodacom, a major sponsor of sport in South Africa, could not be compared with its peers utilising purely financial and statistical methods. Cell C is one of the most prominent sponsors of rugby in South Africa, through its title sponsorship of the Cell C Sharks, and was not included in this study as it is not listed on the JSE. It is suggested that such companies should be included in a qualitative study approach.

The results of the Mann-Whitney U test for the consumer services and financial sectors confirm no significant difference in EPS growth for companies utilising consistent sports sponsorship as part of their marketing mix to those that do not. The consumer services sector has seen above-average revenue growth from sports sponsorship compared with its sector peers; however, the sector was unable to convert this increased revenue growth into increased profits, suggesting that the cost of sponsoring, as well as the operating costs associated with sports sponsorship, counteract any growth in revenue.

The sample of sports-sponsoring companies experienced a larger annual mean EPS growth rate of 30.6 per cent compared to the remaining JSE Main Board companies which grew EPS annually at 27.4 per cent. The results of the Mann-Whitney U test confirm a significant difference in EPS growth for companies utilising consistent sports sponsorship as part of their marketing mix. From a practical interpretive perspective, this result reveals that those companies in South Africa involved in sports sponsorship consistently attain greater than market-related profit growth. This poses some interesting points for discussion, given that revenue growth was not statistically different, which suggests that many sponsors are utilising the sponsorships for purposes other than sales growths that result in a profitable outcome. The potential range of options is large but would likely comprise the creation of stronger supplier relationships, resulting in optimised business inputs. Sponsors might be utilising sponsorships to improve corporate social status, which assists them in creating regulatory compliance, in some instances. Additionally, these sponsorships may be utilised to maintain key client relationships that provide the highest levels of profitability, and whilst this might not grow revenue through new business acquisition, it may result in higher profitability as a result of a loyal and stable customer base.

Much of the available research focusses on the sponsorship of specific sporting events and the share price impact thereof at specific occasions like the announcement, renewal and termination. Where research is conducted across a multitude of sporting events and codes, this predominantly focusses on share price performance only, with varying and somewhat inconclusive results. There is little research focussing on wider, more comprehensive sets of sponsored events and sporting codes, and that seeks to provide an understanding of financial returns for sponsoring properties. In a study of more than 50 US-based corporations it was found that, as a group, corporations which consistently invested in sports sponsorships outperformed market averages, and that those with higher sponsorship spend achieved higher returns (Jensen and Hsu, 2011). The study utilised descriptive statistics. More analysis, utilising detailed statistical analysis, is required to better understand the effects of sponsorship on the wider set of variables analysed. In this case, a five-year compound annual growth rate was calculated for stock price appreciation, total revenue, net income and EPS, and analysed descriptively with only means and standard deviation. Measurement of such variables assists with an understanding of the materialized results of sponsorship as opposed to much of the work in this field, which analyses market reactions to sponsorship announcements.

This paper examines how contemporary workplace surveillance can simultaneously incentivize and commodify workforce behavior. Specifically, workplace surveillance is reconceptualized as rent-seeking, which offers a framework for analyzing novel employer-employee relationships stemming from alternate views of risk and reward.

The case of workplace microchipping is studied qualitatively as a backdrop for theorizing emergent labor relations in the context of surveillance capitalism and biopolitics.

Reconsidering surveillance within the context of personal risk and entrepreneurial lure offers much to 21st century discourse on labor and supervision. It is imperative that the public sector engages in appropriate regulatory protocols to manage emergent behavior in organizations.

This study departs from the popular conceptualization of human microchipping as an intersection of legal and ethical considerations of surveillance. Instead, the authors examine a different aspect of the microchipping phenomenon, taking into account employee creative reactions to employer surveillance in the context of risk and return.

Rankings have become a popular topic in the social sciences over the past two decades. Adding to these debates, the present volume assembles studies that explore a variety of empirical settings, emphasizing the importance of acknowledging that there are multiple “Worlds of Rankings.” To this end, the first part of the chapter addresses the implications of two modes of criticism that characterize much of the scholarly work on rankings and summarizes extant conceptual debates. Taking stock of what we know, the second part distinguishes three areas of empirical research. The first area concerns the activities of those who produce rankings, such as the collection of data or different business strategies. Studies in the second area focus on inter-organizational, field-level, or discursive phenomena, particularly how rankings are received, interpreted, and institutionalized. The third area covers the manifold effects that research has unveiled, ranging from the diffusion of practices and changes in organizational identities to emotional distress. Taken together, the contributions to this volume expand our knowledge in all three areas, inviting new debates and suggesting pathways forward.

This paper aims to explore the biodiversity reporting by a state-owned entity responsible for conserving and protecting biodiversity assets in South Africa, the South African National Parks (SANParks) (SOC) Limited.

This study uses content analysis to explore and investigate the disclosure themes in the SANParks reports for the period 2013–2017. The frequency of substantive disclosures is also evaluated over a five-year period. The data are presented graphically in frequency charts and supported by descriptive statistics and univariate correlations for non-normal data. This provides insights into the amount of information being disclosed and the interconnections among biodiversity reporting themes.

SANParks has increased its reporting on biodiversity over time. Disclosures are interconnected and deal with a range of issues, including species at risk of extinction, operational considerations, risk management practices and how SANParks evaluates its environmental performance. The information is detailed and included in different parts of the organisation’s annual reports suggesting a genuine commitment to protecting biodiversity. There are areas for improvement but SANParks frames biodiversity as a central part of its strategy, operations and assurance processes something which would not occur if the disclosures were only about managing impressions.

The study is among the first to explore biodiversity disclosure themes in a state-owned entity in Africa, responsible for the conservation. While the study deals with a specific case entity, the findings are broadly applicable for other organisations keen on constructing a biodiversity account.
