Assessing the impact of affective feedback on end-user security awareness

A lack of awareness regarding online security behaviour can leave users and their devices vulnerable to compromise. This paper highlights potential areas where users may fall victim to online attacks, and reviews existing tools developed to raise users’ awareness of security behaviour. An ongoing research project is described, which provides a combined monitoring solution and affective feedback system, designed to provide affective feedback on automatic detection of risky security behaviour within a web browser. Results gained from the research conclude an affective feedback mechanism in a browser-based environment, can promote general awareness of online security

Reducing risky security behaviours:utilising affective feedback to educate users

Despite the number of tools created to help end-users reduce risky security behaviours, users are still falling victim to online attacks. This paper proposes a browser extension utilising affective feedback to provide warnings on detection of risky behaviour. The paper provides an overview of behaviour considered to be risky, explaining potential threats users may face online. Existing tools developed to reduce risky security behaviours in end-users have been compared, discussing the success rate of various methodologies. Ongoing research is described which attempts to educate users regarding the risks and consequences of poor security behaviour by providing the appropriate feedback on the automatic recognition of risky behaviour. The paper concludes that a solution utilising a browser extension is a suitable method of monitoring potentially risky security behaviour. Ultimately, future work seeks to implement an affective feedback mechanism within the browser extension with the aim of improving security awareness

Create Differentiation: Rugby for Recruiting Student-Athletes

Universities in the U.S. are competing aggressively for every student, especially students paying most, if not all, their tuition, minimizing discounts or scholarships, and increasing the student R.O.I. Traditionally, institutions have used athletics to recruit students. However, recruiting in this manner is lost in the noise today. Institutions need to differentiate themselves while protecting their profitability and creating separation between them and their competition. Rugby is the fastest-growing full-contact sport for men and women in the U.S. and it is also the only full-contact sport for women. A well-developed and executed rugby program can be that differentiation. This paper suggests a model that implements this differentiation

Diabatic balance model for the equatorial atmosphere

Using an asymptotic expansion, a balance model is derived for the shallow-water equations (SWE) on the equatorial beta-plane that is valid for planetary-scale equatorial dynamics and includes Kelvin waves. In contrast to many theories of tropical dynamics, neither a strict balance between diabatic heating and vertical motion nor a small Froude number is required. Instead, the expansion is based on the smallness of the ratio of meridional to zonal length scales, which can also be interpreted as a separation in time scale. The leading-order model is characterized by a semigeostrophic balance between the zonal wind and meridional pressure gradient, while the meridional wind v vanishes; the model is thus asymptotically nondivergent, and the nonzero correction to v can be found at the next order. Importantly for applications, the diagnostic balance relations are linear for winds when inferring the wind field from mass observations and the winds can be diagnosed without direct observations of diabatic heating. The accuracy of the model is investigated through a set of numerical examples. These examples show that the diagnostic balance relations can remain valid even when the dynamics do not, and the balance dynamics can capture the slow behavior of a rapidly varying solution

Effective strategies to strengthen the mental health and wellbeing of Aboriginal and Torres Strait Islander people

Introduction: The purpose of this paper is to draw on Aboriginal and Torres Strait Islander (Indigenous) perspectives, theoretical understandings, and available evidence to answer questions about what is required to effectively address Indigenous people’s mental health and social and emotional wellbeing. Social and emotional wellbeing is a multifaceted concept. Although the term is often used to describe issues of ‘mental health’ and ‘mental illness’, it has a broader scope in that Indigenous culture takes a holistic view of health. It recognises the importance of connection to land, culture, spirituality, ancestry, family and community, how these connections have been shaped across generations, and the processes by which they affect individual wellbeing. It is a whole-of-life view, and it includes the interdependent relationships between families, communities, land, sea and spirit and the cyclical concept of life–death–life. Importantly, these concepts and understandings of maintaining and restoring health and social and emotional wellbeing differ markedly to those in many non-Indigenous-specific (or mainstream) programs that tend to emphasise an individual’s behavioural and emotional strengths and ability to adapt and cope with the challenges of life. This paper explores the central question of ‘what are culturally appropriate mental health and social and emotional wellbeing programs and services for Indigenous people, and how are these best delivered?’. It identifies Indigenous perspectives of what is required for service provision and program delivery that align with Indigenous beliefs, values, needs and priorities. It explores the evidence and consensus around the principles of best practice in Indigenous mental health programs and services. It discusses these principles of best practice with examples of programs and research that show how these values and perspectives can be achieved in program design and delivery. This paper seeks to provide an evidence-based, theoretically coherent discussion of the factors that influence the effective development, implementation and outcomes of initiatives to address Indigenous mental health and wellbeing issues. It seeks to assess whether the current investment in Indigenous people’s mental health is aligned with available evidence on what works. To this end, the paper reviews Australian literature and government health, mental health and social and emotional wellbeing policies and programs. The scope of programs and their criteria for inclusion in this paper are informed by the Key Result Area 4, Social and Emotional Wellbeing objectives, within the National Strategic Framework for Aboriginal and Torres Strait Islander Health 2003–13: Australian Government Implementation Plan 2007–2013. This paper acknowledges the holistic nature of health, mental health and wellbeing, and the effects of Australia’s colonial history and legacy on the contemporary state of Indigenous social and emotional wellbeing. It recognises that there is a complex relationship between social and emotional wellbeing, harmful substance misuse, suicide, and a range of social and economic factors. Although this paper encompasses the broad priorities identified within the key Indigenous mental health policies and frameworks, it does not provide a detailed discussion of programs and resources that, although relevant here, are covered in a number of existing Closing the Gap Clearinghouse resource sheets and issues papers (see Appendix 1). These interweavings and overlaps are not surprising given the complexity and interconnectedness of the issues and determinants that are being addressed to strengthen Indigenous mental health and wellbeing

Canvas Five Year LMS Accreditation Reporting Using Rubrics and Assignments

There is a surprisingly large gap between measuring inputs to a program and outputs from that program. Accreditation requirements have added an increasingly burdensome workload to degree-plan and course administration. The ease with which one can design assignments and their corresponding rubrics does not freely translate to assessing student response to those assignments. The challenge is to deploy assessment tools that are easy to understand, administer, deploy, and learn from. This paper focuses on the assessment of assignments evaluated by detailed rubrics. We describe tools and processes that enable us to examine years of data at a granularity not directly supported by our LMS

The therapeutic effect of dietary nitrate supplementation in healthy adults, individuals with type 2 diabetes mellitus and chronic obstructive pulmonary disease.

Introduction and aim Increases in the bioavailability of nitric oxide have been shown to reduce the oxygen (O2) cost of exercise, improve exercise performance, alter gastric blood flow and mediate glucose uptake in healthy individuals. Aim; does dietary nitrate reduce the O2 cost of exercise, improve walking performance in individuals with type 2 diabetes mellitus (T2DM) and chronic obstructive pulmonary disease (COPD) or alter hepatic diffusion and positively affect glucose homeostasis in healthy adults? Methods Experimental chapters utilised a double-blind, placebo-controlled, randomised, experimental design. Breath by breath pulmonary gas analysis was utilised to assess the O2 cost of exercise in 48 individuals with T2DM and 13 with COPD. Walking performance was assessed via the six minute walk test (6MWT) in cohorts 1 and 2. Magnetic resonance imaging was used to assess portal vein flux, velocity and the apparent diffusion coefficient, in order to assess hepatic microvascular diffusion (apparent diffusion coefficient (ADC)). Blood pressure (BP) was measured in all trials. Results Relative to placebo, beetroot juice resulted in a significant increase in plasma nitrate and nitrite. There were no differences between placebo vs. beetroot juice for the O2 cost of walking (T2DM: placebo; 946 ± 221 vs. beetroot juice; 939 ± 223 ml.min-1; P=0.59) or cycling (COPD: placebo; 933 ± 323 vs. beetroot juice; 939 ± 302 ml: min-1; P=0.88), distance covered in the 6MWT (T2DM: placebo; 550 ± 83 vs. beetroot juice; 554 ± 90m; P=0.17 or COPD: placebo; 456 ± 86 vs. beetroot juice; 449 ± 79 m; P=0.37) or BP (T2DM: systolic: placebo; 134 ± 10 vs. beetroot juice; 132 ± 12 mmHg, P=0.17; diastolic: placebo; 77 ± 7: vs. beetroot juice; 76 ± 11 mmHg, P=0.27. COPD: systolic: placebo; 123 ± 14 vs. beetroot juice; 123 ± 14 mmHg; P=0.91; diastolic: placebo; 77 ± 9 vs. beetroot juice; 79 ± 9 mmHg; P=0.27). No differences were seen between placebo and beetroot juice for ADC (young adults: F(3, 45) = 0.25, P = 0.74; older adults; F(3, 42) = 1.3, P = 0.28), portal vein flux (young adults: F(3, 45) = 0.339, P = 0.79; older adults; F(3, 42) = 1.65, P = 0.19) however, there was an interaction effect in the young adults: (F(3, 45) = 2.9, P = 0.04) but not in the older adults; F(3, 42) = 1.8, P = 0.16) between visits for portal vein velocity. Nitrate supplementation did not reduce plasma glucose concentrations (young adults: F(3, 45) = 0.96, P = 0.42; older adults; F(3, 42) = 0.04, P = 0.99). Nitrate supplementation did not reduce systolic blood pressure (young adults: F(3, 45) = 0.20, P = 0.89; older adults; F(3, 42) = 1.7, P = 0.18) or diastolic blood pressure (young adults: F(3, 45) = 0.25, P = 0.86; older adults; F(3, 42) = 0.45, P = 0.72). Conclusion Dietary nitrate supplementation does not alter the O2 cost of exercise, improve walking performance or reduce BP in individuals with T2DM or COPD. Nitrate supplementation does not alter hepatic diffusion, glucose homeostasis or BP.University of Exete

Is RAS the Link Between COVID-19 and Increased Stress in Head and Neck Cancer Patients?

The COVID-19 pandemic emerged as a largely unexplained outbreak of pneumonia cases, in Wuhan City, China and rapidly spread across the world. By 11th March 2020, WHO declared it as a global pandemic. The resulting restrictions, to contain its spread, demanded a momentous change in the lifestyle of the general population as well as cancer patients. This augmented negative effects on the mental health of patients with head and neck cancer (HNC), who already battle with the stress of cancer diagnosis and treatment. The causative agent of COVID-19, SARS-CoV2, gains entry through the Angiotensin converting enzyme 2 (ACE2) receptor, which is a component of the Renin Angiotensin System (RAS). RAS has been shown to influence cancer and stress such that it can have progressive and suppressive effects on both. This review provides an overview of SARS-CoV2, looks at how the RAS provides a mechanistic link between stress, cancer and COVID-19 and the probable activation of the RAS axis that increase stress (anxiogenic) and tumor progression (tumorigenic), when ACE2 is hijacked by SARS-CoV2. The mental health crises brought about by this pandemic have been highlighted in many studies. The emerging links between cancer and stress make it more important than ever before to assess the stress burden of cancer patients and expand the strategies for its management

Cancer and Stress:Does It Make a Difference to the Patient When These Two Challenges Collide?

A single head and neck Cancer (HNC) is a globally growing challenge associated with significant morbidity and mortality. The diagnosis itself can affect the patients profoundly let alone the complex and disfiguring treatment. The highly important functions of structures of the head and neck such as mastication, speech, aesthetics, identity and social interactions make a cancer diagnosis in this region even more psychologically traumatic. The emotional distress engendered as a result of functional and social disruption is certain to negatively affect health-related quality of life (HRQoL). The key biological responses to stressful events are moderated through the combined action of two systems, the hypothalamus–pituitary–adrenal axis (HPA) which releases glucocorticoids and the sympathetic nervous system (SNS) which releases catecholamines. In acute stress, these hormones help the body to regain homeostasis; however, in chronic stress their increased levels and activation of their receptors may aid in the progression of cancer. Despite ample evidence on the existence of stress in patients diagnosed with HNC, studies looking at the effect of stress on the progression of disease are scarce, compared to other cancers. This review summarises the challenges associated with HNC that make it stressful and describes how stress signalling aids in the progression of cancer. Growing evidence on the relationship between stress and HNC makes it paramount to focus future research towards a better understanding of stress and its effect on head and neck cancer
