Exploring Workers' Subjective Experiences of Habit Formation in Cybersecurity:A Qualitative Survey

Employee behaviors remain at the center of the cybersecurity of workplaces, despite the challenges they face in doing so. Time pressures and competing demands mean that users tend to rely on habitual behaviors that often run counter to good cybersecurity practice. One possible solution may be to encourage positive habit formation. Designing such interventions, however, relies on knowledge of the perception and experience of habit formation in the context of cybersecurity. To this end, a qualitative survey containing open-ended questions was completed by 195 participants (mean age = 35.51, 53 percent female) recruited via an online participant panel. Participants were asked what cybersecurity behaviors they perform at work and how they believe any habits were prompted, formed, and maintained. Thematic analysis identified three over-arching themes: (a) forming habits unavoidably or unconsciously (some were mandated, or formed without conscious awareness), (b) consciously cultivating habits (including the roles of intrinsic motivation and external prompts), and (c) social and organizational influences (including the influence of occupational culture, social modeling, previous experiences, and information gathering practices). Based on these findings, we present guidelines for supporting workplace cybersecurity habit formation reflecting these subjective experiences, namely introducing automatic solutions, facilitating external cues, fostering interest in cybersecurity issues among employees, creating a positive cybersecurity occupational culture and highlighting positive behavior, and providing access to accessible cybersecurity information to employees. These results constitute a first step in identifying how habits can be exploited for positive cybersecurity behavior change in a way that accounts for the reliance on habitual behaviors in busy, time-pressured workplaces

Welcome to the motherland. An exploration into how experience is storied through generations of African Caribbean immigrants

My research explores the ways in which African Caribbean families communicate with each other and the outside world in the context of living in England. This research interest is heavily influenced by my experience of migration to England. As an African Caribbean person on arrival in England my voice was met with mockery and often resulted in confusion. My professional experience of working within a Child and Adolescent Mental Health service highlighted a limited understanding of African Caribbean migrants and their descendants, and the extent to which they have to negotiate their lived experience. My research questions are: How do first generation Caribbean migrants tell their stories of migration and integration? How do they construct, contest, negotiate identities within this? What if any stories, sayings from the Caribbean do they draw on to help them navigate their new context? How does the next generation negotiate, construct, context identities within these stories/experiences? The methodology section is divided into two distinct areas, the theory and the practical application. The focus is on post-modernist ideas of social construction and the critique of power in relation to the research process. In this I acknowledge the constitutive role of storytelling for the human experience. Using a semi-structured schedule, I interviewed two generations in an intergenerational dyad. The requirements were that one generation had to be a first generation migrant and the other had to be a second generation migrant or later. This allowed for sharing of stories in the presence of the next generation where meaning could be made together. The data has been analysed using the Big and Small Story in Narrative Inquiry. This process is akin to the therapeutic process where we engage both the story of how we came to therapy (presenting issue) but pay attention to the manner and style in which this story is told, what identities are being claimed, what’s being deferred or avoided in the telling. I discovered that the African Caribbean person is a highly politicised human being for whom the racialised and cultural context is a significant part of life. I set out my key findings using the positions of three types of archetypal themes: the trickster, passer/conformer and resister/revolutionary. These were used to capture different ways people responded to power within their daily life. The most significant part of my findings is Dubois’ (1903) concept of double consciousness. This idea describes the way black people carry their negotiations with power. There is a sense that they are constantly having to think about what is acceptable to the power base and how can this be negotiated. Interestingly, the African Caribbean people in my study didn’t name racism, oppression, or politics, so the practitioner has to. I invite practitioners to support what is being called ‘anti colonial practice’ (Heath, 2018). This practice acknowledges that the colonial presence is still active and to really undo this we have to engage in purposeful direct action. This requires a kind of “self-reflexivity plus”. This means engaging in the language of the clients, thinking about your actions with other critical thinkers, questioning your questions with yourself and others, and working with a transparency where we can see whether you have been helpful

FUNCTIONAL EFFECTS OF DIET INDUCED OBESITY ON PERMEABLIZED RAT MUSCLE FIBRES

INTRODUCTION Muscle performance is determined by the metabolic, calcium handling, and sarcomeric characteristics of its constituent fibres. Diet induced obesity (DIO) may influence contractile performance in whole muscle, but little is known about the effects of DIO at the single fibre level. Particularly, how DIO might influence the contractile characteristics of single fibres free from the influence of metabolic or calcium handling properties is not established. There is some limited evidence to suggest that DIO may influence the sarcomeric proteins. For example, troponin T, an important regulatory protein found on the thin filament, exhibits a shift from the fast T3 isoform, to the slow T1 isoform, in mouse soleus muscle following high fat feeding, with no associated change in myosin heavy chain isoform [1]. These results suggest that DIO may cause fast fibres to express slow isoforms of sarcomeric proteins in postural muscles of mixed fibre-type. The purpose of this study was to assess the force-calcium and force-velocity relationships of skinned fast and slow fibres of vastus intermedius, a mixed fibre-type postural muscle [2], in chow-fed rats and a rat model of DIO. It was hypothesized that fast fibres from DIO rats would exhibit characteristics associated with a slower fibre phenotype, including increased calcium sensitivity and lower shortening velocities. METHODS Individually housed male Sprague-Dawley rats, aged 10-12 weeks, were randomized to undergo diet induced obesity (DIO) where they were fed a high fat, high sugar diet (n = 6) or a standard chow diet (n = 6) for 12 weeks. The caloric content of DIO diets was 40% fat and 45% sucrose, compared to chow diets which consisted of 12% fat and 0% sucrose. Both vastus intermedius muscles were collected from each rat. Similar to the mouse soleus, the fibre type distribution of rat vastus intermedius is approximately 50% type I and 50% type IIa fibres [2]. Muscles were chemically skinned in a glycerol-rigor solution for 2 weeks.  Two fast and two slow fibres per animal were then isolated and mounted in a model 802B skinned fibre test system (Aurora Scientific) at 2.4 µm sarcomere length for testing.  Preliminary fibre type assessment was made using a strontium sensitivity test [3].  The force-pCa relationship was assessed from pCa 7.2 to pCa 4.2. The force-velocity relationship was assessed by measuring the shortening velocity during isotonic contractions.  Maximal shortening velocity (Vmax) was assessed by a slack test protocol. Statistical differences were determined using Student’s t-test or a two-way factorial ANOVA and Newman-Keuls post-hoc analysis as appropriate, α = 0.05. RESULTS Dual-energy X-ray absorptiometry scans revealed DIO rats had significantly higher body mass, fat mass, and greater percent body fat than chow fed rats (all p<0.05), while lean mass was not significantly different between groups. DIO did not affect the force per cross-sectional area (CSA) of skinned fibres (Table 1). Fast DIO fibres had significantly lower maximum shortening velocities when compared to fast chow fibres (p<0.05; Table 1). No such differences were observed in slow fibres. Independent of fibre type, DIO fibres had significantly higher calcium sensitivity than chow fibres (p<0.01, Table 1).  While the Hill coefficient of the force pCa relationship was different between fast and slow chow fibres, no differences were seen in DIO fibres (p<0.05; Table 1).DISCUSSION AND CONCLUSIONS Consistent with a fast to slow phenotype transition, Vmax was lower in fast DIO fibres. However, DIO influenced the force-calcium relationship of both fast and slow fibres. Therefore, adaptations are not limited to fast fibres, but rather influence contractility on a larger scale. Whether this influence is global or localized to postural muscles remains to be determined. The specific isoforms of contractile proteins expressed in single fibres should be assessed following DIO

Executive Pay and Performance:The Moderating Effect of CEO Power and Governance Structure

This paper examines the crucial question of whether chief executive officer (CEO) power and corporate governance (CG) structure can moderate the pay-for-performance sensitivity (PPS) using a large up-to-date South African dataset. Our findings are three-fold. First, when direct links between executive pay and performance are examined, we find a positive, but relatively small PPS. Second, our results show that in a context of concentrated ownership and weak board structures; the second-tier agency conflict (director monitoring power and opportunism) is stronger than the first-tier agency problem (CEO power and self-interest). Third, additional analysis suggests that CEO power and CG structure have a moderating effect on the PPS. Specifically, we find that the PPS is higher in firms with more reputable, founding and shareholding CEOs, higher ownership by directors and institutions, and independent nomination and remuneration committees, but lower in firms with larger boards, more powerful, and long-tenured CEOs. Overall, our evidence sheds new important theoretical and empirical insights on explaining the PPS with specific focus on the predictions of the optimal contracting and managerial power hypotheses. The findings are generally robust across a raft of econometric models that control for different types of endogeneities, pay, and performance proxies

An analysis of trends, frequencies and factors influencing the development of resistance to phosphine in the red flour beetle Tribolium castaneum (Herbst) in Australia

Although resistance to phosphine, the key disinfestant used worldwide in the stored grain environment has been an ongoing industry issue, studies on its trend over large geographic region and over long period of time is very limited. In this study, we critically analysed 20 years' phosphine resistance diagnosis data for the red flour beetle Tribolium castaneum (Herbst) stored in the Australian Grain Insect Resistance Database. Resistance diagnosis on a staggering 6336 samples, along with information on storage types and treatment history was interrogated to establish trends and frequencies of resistance development in this species and factors that may have contributed towards these resistance occurences. Using descriptive statistics, linear and trend analysis and a well established Bayesian hurdle model, we determined that strong resistance in T. castaneum was significantly more prevalent in quarantine intereceptions than in central storages and on farms. The strong resistance incidences had been confined to eastern states of Queensland, New South Wales, Victoria and South Australia, whereas it is yet to be detected in the state of Western Australia. We could not establish any significant correlation between the strong resistance development and any commodity or treatments. After an initial increasing trend in incidences since the first detection of strong resistance in 1997 in this species, the frequency was stabilised during 2001–08; after which there had been an upward trend since 2009 till the last survey in 2013. The conclusions derived from this analyses highlighted the importance of a resistance monitoring program with relevant information being used in Australia as the basis for ongoing and future phosphine resistance management strategies. This research may also proved valuable towards devising similar strategies in overseas countries with phosphine resistance problems

Provision of Outdoor Nature-Based Activity for Older People with Cognitive Impairment: A Scoping Review from the ENLIVEN Project

© 2023 Rachel Collins et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.The health and well-being benefits of outdoor nature-based activity are increasingly recognised, but older people with cognitive impairment face significant barriers to access. The ENLIVEN project aims to promote access by gathering evidence and coproducing guidance for activity providers. As part of this project, we conducted a scoping review to characterise the types of outdoor nature-based activity for older people with dementia and other forms of cognitive impairment for which research evidence is available and the range of outcomes is examined. The protocol is available online. We systematically searched relevant databases from 1st January, 2009, to 20th October, 2022, and screened articles against the following criteria: participants were older people aged 65 and above with cognitive impairment arising from dementia or another health condition. The study described the formal provision of outdoor nature-based activity away from the person’s usual place of residence, and at least one outcome of participation in the activity was evaluated. Twenty-eight articles met inclusion criteria, all focused on people living with dementia. In most cases, participants were attending day care or living in residential care, and sample sizes ranged from 4 to 136. Activities fell into three groups: green day care (fifteen articles), equine-assisted interventions (seven articles), and community nature-based activities (six articles). Outcome domains explored were connection with nature, activity engagement, impacts on clinical symptoms, functional ability, physical, psychological, and social health, and quality of life. Outdoor nature-based activity can be offered as an opportunity for meaningful occupation to enrich daily life, as a framework for day care provision, or as an intervention to address clinical needs. The evidence base for green day care is relatively established, but the potential for addressing specific clinical needs remains to be explored. The paucity of evidence regarding community provision, especially for those not attending formal care settings, suggests the need for effective knowledge exchange to stimulate initiatives in this area.Peer reviewe

Is it feasible to conduct a randomised controlled trial of pretransplant exercise (prehabilitation) for patients with multiple myeloma awaiting autologous haematopoietic stem cell transplantation? Protocol for the PREeMPT study

Introduction While myeloma is an incurable malignancy, developments in disease management have led to increased life expectancy in recent years. Treatment typically involves stem-cell transplantation. Increased survival rates equate to more patients living with the burden of both the disease and its treatment for increasing number of years, rendering myeloma a long-term condition. Evidence exists to demonstrate the benefits of exercise for patients recovering from stem-cell transplantation, and prehabilitation—exercise before treatment—has been shown to be effective in other disease areas. To date there has been no research into prehabilitation in patients with myeloma awaiting transplantation treatment. Our objective is to determine whether it is feasible to conduct a randomised controlled trial into pretransplant exercise for patients with multiple myeloma who are awaiting autologous stem-cell transplantation. Methods and analysis This mixed methods study identifies patients with diagnosis of multiple myeloma who have been assigned to the autologous transplantation list and invites them to participate in six weekly sessions of individualised, supervised exercise while awaiting transplantation. Quantitative data to determine feasibility targets include rates of recruitment, adherence and adverse events, and outcome measures including 6 min walking distance test and quality of life. Qualitative interviews are undertaken with a purposive sample of patients to capture their experiences of the study and the intervention. Ethics and dissemination Ethics committee approval has been obtained. Dissemination will be through open-access publications and presentations and will seek to reach multiprofessional bases as well as patients and carer groups, addressing the widespread interest in this area of research.

Data on incidence of resistance to phosphine over the last 20 years and factors associated with insect sample collection are stored in the Australian Grain Insect Resistance Database. The database was analysed using descriptive statistics, linear trend analysis and Bayesian hurdle modelling to gain insights into factors contributing to the development of strong resistance in Rhyzopertha dominica. Descriptive statistics indicated that strong resistance was significantly more common in central storages, particularly bunker storages, than on farms. Strong resistance in R. dominica was also associated with wheat, barley and sorghum but there was no significant link to any grain protectant or storage treatment chemical, other than phosphine. Highest frequency of strong resistance was found in northern New South Wales and no detections were made in Western Australia. In eastern Australia, trend analysis indicated that strong resistance detections increased steadily from the first detection in 1997 to about 8% of samples containing resistant insects in 2014. Weak resistance was detected in about 10% of samples in eastern Australia in the early 1990s but this increased rapidly to 40–50% by 1990, at the same time that industry use of phosphine greatly increased, and then to about 80% in 1995. Strong resistance was first detected in this species when weak resistance was diagnosed in close to 80% of population samples. The Bayesian hurdle model identified bunkers, silos and unsealed storages as being associated with development of strong resistance and sheds with a lower frequency. This model also identified an accelerated increase in resistance frequency of strong resistance from 2011 to present. The information gained from this analysis is being used to inform current and future management of resistance to phosphine
