Evaluating decontamination methods for mobile devices
Introduction
The use of mobile devices within healthcare settings by staff, patients and visitors is widespread and growing. DoH guidance states that patients should be allowed the widest possible use of mobile phones. For staff mobile devices have become an essential aspect of their day-to-day professional and personal lives. There is, however, clear evidence that phones/tablets can be contaminated with pathogens, which may survive for prolonged periods before being transferred onto hands or other surfaces. This quantitative study evaluates the ability of a range of technologies to decontaminate iPads.
Â
Methods
The front, back and sides of iPads were contaminated with a standard suspension of Staphylococcus aureus. Half of these surfaces were sampled to provide pre-values, whilst the other half was decontaminated with either alcohol wipes, detergent wipes, quaternary ammonium impregnated wipes, or exposure to Ultraviolet light for either 30 or 60 seconds. As a control, a microfibre cloth impregnated with sterile water was also tested.
Â
Results
Alcohol based wipes were most effective, generating on average a 2 log reduction on the back of the iPad and a 3 log reduction on the front. The cleaning of the front surface of the iPad was consistently easier to clean that the back. However, all of the wipes were less effective than UV exposure, where a 60 second exposure generated a 4 log reduction on the front and a 3.5 log reduction on the back.
Â
Discussion
The results indicate that commercial wipes are unable to effectively decontaminate the high touch surfaces of an iPad. However, the application of a UV decontamination technology was a much more effective method for the removal of bacteria from these surfaces. This suggests that UV based decontamination technology would provide a quick, efficient and economical method for the disinfection of mobile devices such as iPads in healthcare settings
Do Borrower Rights Improve Borrower Outcomes? Evidence from the Foreclosure Process
We evaluate laws designed to protect borrowers from foreclosure. We find that these laws delay but do not prevent foreclosures. We first compare states that require lenders to seek judicial permission to foreclose with states that do not. Borrowers in judicial states are no more likely to cure and no more likely to renegotiate their loans, but the delays lead to a build-up in these states of persistently delinquent borrowers, the vast majority of whom eventually lose their homes. We next analyze a âright-to-cureâ law instituted in Massachusetts on May 1, 2008. Using a difference-in-differences approach to evaluate the effect of the policy, we compare Massachusetts with neighboring states that did not adopt similar laws. We find that the right-to-cure law lengthens the foreclosure timeline but does not lead to better outcomes for borrowers.
The Engineering Hubs and Spokes Project - institutional cooperation in educational design and delivery
The emergence of blended learning techniques that embrace a combination of face-to-face and
online learning environments offers a raft of opportunity for flexibility in education. While much
writing has focused on the opportunities for flexibility for the students and teachers, this paper
focuses on the opportunities for effective sharing of expertise and effort between institutions.
The Engineering 'Hubs and Spokes' project is a collaboration between The Australian National
University and the University of South Australia. It draws on the strengths of each to improve the
range and quality of educational opportunities for students. Two components of the project are
underpinned by blended teaching and learning techniques: sharing of courses at the advanced
undergraduate level; and development of an integrated graduate development program.
We describe choices made, benefits identified, and the challenges encountered in the early stages
of the project. We discuss recommendations for the future of cooperation in educational design
and delivery, and comment on the opportunities that arise for structural reform of the higher
education sector
No evidence for a culturable bacterial tetrodotoxin producer in Pleurobranchaea maculata (Gastropoda: Pleurobranchidae) and Stylochoplana sp. (Platyhelminthes: Polycladida)
Tetrodotoxin (TTX) is a potent neurotoxin found in the tissues of many taxonomically diverse organisms. Its origin has been the topic of much debate, with suggestions including endogenous production, acquisition through diet, and symbiotic bacterial synthesis. Bacterial production of TTX has been reported in isolates from marine biota, but at lower than expected concentrations. In this study, 102 strains were isolated from Pleurobranchaea maculata (Opisthobranchia) and Stylochoplana sp. (Platyhelminthes). Tetrodotoxin production was tested utilizing a recently developed sensitive method to detect the C9 base of TTX via liquid chromatographyâmass spectrometry. Bacterial strains were characterized by sequencing a region of the 16S ribosomal RNA gene. To account for the possibility that TTX is produced by a consortium of bacteria, a series of experiments using marine broth spiked with various P. maculata tissues were undertaken. Sixteen unique strains from P. maculata and one from Stylochoplana sp. were isolated, representing eight different genera; Pseudomonadales, Actinomycetales, Oceanospirillales, Thiotrichales, Rhodobacterales, Sphingomonadales, Bacillales, and Vibrionales. Molecular fingerprinting of bacterial communities from broth experiments showed little change over the first four days. No C9 base or TTX was detected in isolates or broth experiments (past day 0), suggesting a culturable microbial source of TTX in P. maculata and Stylochoplana sp. is unlikely
Coworker Influence
What is coworker influence? Coworkers are the individuals in an organization that regularly work with a given employee, often performing similar tasks or collaborating in some way. Coworkers are typically in a similar hierarchical position in the organizational structure, differentiating them from subordinates, supervisors, or managers. Coworker influence is about how coworkers impact a given employeeâs work experiences. There are two facets of coworker influenceâcoworker support and coworker antagonism (Chiaburu & Harrison, 2008). Coworker support is a positive influence, including desirable actions and behaviors. More specifically, there are two types of coworker supportâinstrumental and affective (Chiaburu & Harrison, 2008). Instrumental support is provided through information or behavioral means, whereas affective support is provided through emotional means. Instrumental support can take the form of helping with a task or problem, and emotional support can include positive emotions such as friendliness or encouragement (Chiaburu & Harrison, 2008). Coworker antagonism is the negative side of influence, involving undesirable actions and behaviors, such as incivility and social undermining (Chiaburu & Harrison, 2008). There is no primary measure for assessing all dimensions of coworker influence. Instead, there are a variety of measures that assess different types of influence, sometimes using different labels. Examples of items assessing instrumental support include âgives me helpful feedback about my job performanceâ (Aryee & Luk, 1996) and âprovides me with work-related informationâ (Liaw, Chi, & Chuang, 2010). Affective support measures include items such as âprovides me with encouragementâ (Bacharach, Bamberger, & Biron, 2010) and âwe talk about the good things in our workâ (Zellars & Perrewe, 2001). Finally, antagonism measures include items such as âgives me incorrect or misleading informationâ and âbelittles me or my ideasâ (Duffy, Ganster, & Pagon, 2002). Why is coworker influence important? Coworker Support Coworker influence is important because it is associated with many job attitudes, stress indicators, and behaviors. More specifically, coworker support is moderately associated with job satisfaction and organizational commitment (Chiaburu & Harrison, 2008; Mathieu, Eschleman, & Cheng, 2018; Ng & Sorensen, 2008). It is also moderately associated with thriving October 14, 2020 at work, which means feeling energized and experiencing continual growth (Kleine, Rudolph, & Zacher, 2019). With respect to stress indicators, coworker support is moderately associated with various types of role stress (i.e., role conflict, role overload, and role ambiguity; Chiaburu & Harrison, 2008; Mathieu et al., 2018) and with burnout (Halbesleben, 2006; Mathieu et al., 2018). Coworker support is most strongly connected with role ambiguity, such that employees with coworker support are less likely to be unclear about their job expectations and responsibilities (Chiaburu & Harrison, 2008; Mathieu et al., 2018;). In terms of behavior, coworker support is moderately associated with task performance and modestly associated with citizenship behaviors, which are discretionary extra-role behaviors, such as such as volunteering, helping others, and making suggestions for improvement, that benefit the group and organization (Chiaburu & Harrison, 2008). However, there is a stronger connection between coworker support and one specific type of citizenship behaviorâbehaviors that are focused on creating or adapting to change (e.g., solving problems, creating improvements in processes or services, or effectively coping with changing demands; Chiaburu, Lorinkova, & Van Dyne, 2013). That relationship is further strengthened when coworker support is specific, versus just general or generic (i.e., just being generally supportive; Chiaburu et al., 2013). Finally, though coworker support is moderately associated with turnover intentions (Chiaburu & Harrison, 2008; Kim & Kao, 2014; Mathieu et al., 2018; Ng & Sorensen, 2008), it is only modestly associated with actual turnover (Chiaburu & Harrison, 2008; Rubenstein, Eberly, Lee, & Mitchell, 2018). Looking across the various connections, it has been established that affective support is more strongly tied to job attitudes, whereas instrumental support is more strongly tied to employee effectiveness (i.e., task performance and citizenship behaviors; Chiaburu & Harrison, 2008). In addition, many of the connections are stronger in jobs that involve a lot of interpersonal interaction (Chiaburu & Harrison, 2008) or customer service (Ng & Sorensen, 2008). Finally, contrary to some common beliefs about the prominent importance of leaders, many of the comparative findings show that coworker support is either equally or more strongly connected to employee outcomes than leadership support (Chiaburu & Harrison, 2008). Coworker Antagonism Less is known about the negative side of coworker influence, but what is known is consistent with the findings for coworker support. Coworker antagonism is moderately associated with lower job satisfaction, lower organizational commitment, and greater intentions to quit (Chiaburu & Harrison, 2008). Similarly, coworker antagonism is associated with fewer citizenship behaviors, more counterproductive work behaviors, and poorer task performance (Chiaburu & Harrison, 2008). These connections are more pronounced when the antagonism is more severe (e.g., harassment and interpersonal abuse, versus incivility or social undermining; Chiaburu & Harrison, 2008). Overall Considering all the evidence, the strongest findings are such that when employees have coworker support, they are more likely to (a) engage in change-oriented citizenship behaviors (especially when the support is specific, rather than generic), (b) experience job satisfaction (especially in jobs that involve a lot of social interaction), (c) feel energized and experience growth, and (d) be more clear about their job expectations and responsibilities. It is important to note that research on coworker influence thus far has focused on assessing factors that are merely associated with coworker influence, not on testing strategies for improving it or on examining whether improving it affects outcomes like job satisfaction. It is therefore not appropriate to conclude that coworker support causes these outcomes, but they are nonetheless moderately strong connections. Research is needed to explore strategies to boost coworker support (and reduce coworker antagonism) and examine the effect of such changes on employee outcomes. These four outcomes may show the most promise for coworker influence.
