The Forgotten Password: A Solution to Selecting, Securing and Remembering Passwords
Internet passwords are required of us more and more. Personal experience
and research shows us that it is difficult to create and remember unique passwords
that meet security requirements. This study tested a unique method of password
generation based on a selection of mnemonic aids aimed at increasing the
usability, security and memorability of passwords. Fifty-one engineers,
accountants and university students aged between 17 - 61 years participated in the
study. They were randomly assigned to one of three groups: mnemonic, self-selection
and random. All passwords in the study had to meet the following
criteria: they had to be unique, at least eight characters long with a mixture of
letters and numbers, and not include complete words or personal identifiers,
sequential or repetitive numbers, and the passwords could not be written down or
recorded anywhere. The mnemonic group created passwords based on a variety of mnemonic processes, the self-selection group generated passwords that complied with the
above criteria, and the random group were assigned random
passwords generated by the experimenter. Password recall was tested online once
a week for three weeks, and then the passwords were renewed, with participants
staying within the same groups for the length of the study. The second password
was tested weekly for three weeks, then the passwords were renewed for the third
and final time and tested for a further three weeks. The expectation was that the
use of mnemonics in password creation would improve accurate recall of
passwords, more so than if the password was 'self-selected' or a random password
was assigned. The results showed that participants in the mnemonic group were
able to accurately recall all three passwords significantly more often than
participants in the self-selection and random groups. Furthermore, passwords
created by the mnemonic group were more secure than passwords created by the
self-selection group, as their passwords generated had a greater number of
characters in them, slightly larger alphabet size, and a higher degree of entropy.
The results are discussed in terms of the practical relevance of the findings
FORMULATION OF A BUSINESS PLAN FOR A NURSE PRACTITIONER-DRIVEN OUTPATIENT PALLIATIVE CARE CLINIC
Problem: Although empirical evidence demonstrates significant benefits to quality of life and reduction of 30-day hospital readmissions with the intervention of palliative care, outpatient palliative care is not sufficiently available in the targeted metropolitan area. The National Priorities Partnership report identified palliative care as one of six priority areas that would significantly improve the quality of American health care (Meier, 2011). Project Purpose: The purpose of this practice change project was to develop a business plan that determined the feasibility of an outpatient palliative care nurse practitioner-driven clinic. Project Method: Formation of a business plan according to the United States Small Business Administration model, which has six components. Current scholarly evidence related to quality of life and 30-day hospital readmissions was synthesized in preparation for development of the business plan. Project Result: The business plan supports the feasibility of a nurse practitioner outpatient palliative care clinic in addition to traditional care in the Kansas City metropolitan area as a means to increase accessibility to palliative care and to: 1) improve quality of life for patients and families, 2) reduce 30-day hospital readmissions for patients with life-limiting illness
A New, Better BET: Rescuing and Revising Basic Emotion Theory
Basic Emotion Theory, or BET, has dominated the affective sciences for decades (Ekman, 1972, 1992, 1999; Ekman and Davidson, 1994; Griffiths, 2013; Scarantino and Griffiths, 2011). It has been highly influential, driving a number of empirical lines of research (e.g., in the context of facial expression detection, neuroimaging studies and evolutionary psychology). Nevertheless, BET has been criticized by philosophers, leading to calls for it to be jettisoned entirely (Colombetti, 2014; Hufendiek, 2016). This paper defuses those criticisms. In addition, it shows that we have good reason to retain BET. Finally, it reviews and puts to rest worries that BETâs commitment to affect programs renders it outmoded. We propose that, with minor adjustments, BET can avoid such criticisms when conceived under a radically enactive account of emotions. Thus, rather than leaving BET behind, we show how its basic ideas can be revised, refashioned and preserved. Hence, we conclude, our new BET is still a good bet
Self as Teacher: Preliminary Role Identification of the Potential Teaching Candidate
In this study, the researchers used qualitative surveys to explore potential teaching candidatesâ preliminary perceptions of self as teacher and examine how roles are identified, defined and constructed in the context of a tutoring lab that provides support to English Language Learners. Prospective candidatesâ perceptions of their tutees, children whose cultural identities and backgrounds differ from their own, are also examined. Findings indicate participantsâ teaching identities and conceptualizations of their roles as teachers became more specific and elaborated over the course of the semester. Additionally, the significance of multiple practicum experiences in diverse settings for ongoing identity development and for developing knowledge about culturally and linguistically diverse school children was also clear
Interrupting the Pattern: Knowing Why and Respecting Who We Teach
Although research has identified culturally responsive pedagogy (CRP) as vitally important for educators in todayâs increasingly diverse classrooms, few studies exist to explore the development of both pre- and in-service teachersâ knowledge about and self efficacy for CRP. This mixed methods study examined pre- and in-service teachersâ perceptions of CRP as well as their CRP self-efficacy. Both pre-service and in-service teachers participated in professional development aimed at improved knowledge and self-efficacy for CRP. Dependent-samples t-tests revealed positive and statistically significant changes in participantsâ CRP self-efficacy. Qualitative analyses demonstrated participants worked to better understand their core values (know why they teach), identified a need to better understand their students (respect who they teach), and recognized high expectations for all students as a core principle of CRP
College Reconfiguration: Building Faculty Support
Following a year-long discussion, deliberation, and feedback process, faculty and staff in the College of Education and Human Development at Bowling Green State University voted overwhelmingly in support of reconfiguring from five schools and one department to three schools. We discuss our journey and outline the initial benefits, challenges, and lessons of this new configuration
Toward Suicidal Ideation Detection with Lexical Network Features and Machine Learning
In this study, we introduce a new network feature for detecting suicidal ideation from clinical texts and conduct various additional experiments to enrich the state of knowledge. We evaluate statistical features with and without stopwords, use lexical networks for feature extraction and classification, and compare the results with standard machine learning methods using a logistic classifier, a neural network, and a deep learning method. We utilize three text collections. The first two contain transcriptions of interviews conducted by experts with suicidal (n=161 patients that experienced severe ideation) and control subjects (n=153). The third collection consists of interviews conducted by experts with epilepsy patients, with a few of them admitting to experiencing suicidal ideation in the past (32 suicidal and 77 control). The selected methods detect suicidal ideation with an average area under the curve (AUC) score of 95% on the merged collection with high suicidal ideation, and the trained models generalize over the third collection with an average AUC score of 69%. Results reveal that lexical networks are promising for classification and feature extraction as successful as the deep learning model. We also observe that a logistic classifierâs performance was comparable with the deep learning method while promising explainability
Development and Implementation of an Influenza Point-of-Care Testing Service in a Chain Community Pharmacy Setting
Point-of-care testing is becoming increasingly commonplace in community pharmacy settings. These tests are often used in the management of chronic disease, such as blood sugar, hemoglobin A1c and lipid levels, but can also be used for acute conditions such as influenza infection and group A streptococcus pharyngitis. When used for these acute infections, point-of-care tests can allow for pharmacist-initiated treatment. In this study, an influenza point-of-care testing service was developed and implemented in a chain community pharmacy setting and a retrospective review was conducted to assess the service. Of patients tested, 29% tested positive for influenza A and/or B; 92% of patients testing positive received a prescription as a result. While health insurance cannot be billed for the service due to current pharmacy reimbursement practices, this did not appear to negatively affect patient willingness to participate. As point-of-care testing services become more commonplace in community pharmacy settings, patient awareness will similarly increase and allow for more widespread access to acute outpatient care
Exposure to Household Air Pollution from Biomass Cookstoves and Blood Pressure Among Women in Rural Honduras: A CrossâSectional Study
Growing evidence links household air pollution exposure from biomass cookstoves with elevated blood pressure. We assessed crossâsectional associations of 24âhour mean concentrations of personal and kitchen fine particulate matter (PM2.5), black carbon (BC), and stove type with blood pressure, adjusting for confounders, among 147 women using traditional or cleanerâburning Justa stoves in Honduras. We investigated effect modification by age and body mass index. Traditional stove users had mean (standard deviation) personal and kitchen 24âhour PM2.5 concentrations of 126 ÎŒg/m3 (77) and 360 ÎŒg/m3 (374), while Justa stove usersâ exposures were 66 ÎŒg/m3 (38) and 137 ÎŒg/m3(194), respectively. BC concentrations were similarly lower among Justa stove users. Adjusted mean systolic blood pressure was 2.5 mm Hg higher (95% CI, 0.7â4.3) per unit increase in natural logâtransformed kitchen PM2.5 concentration; results were stronger among women of 40 years or older (5.2 mm Hg increase, 95% CI, 2.3â8.1). Adjusted odds of borderline high and high blood pressure (categorized) were also elevated (odds ratio = 1.5, 95% CI, 1.0â2.3). Some results included null values and are suggestive. Results suggest that reduced household air pollution, even when concentrations exceed air quality guidelines, may help lower cardiovascular disease risk, particularly among older subgroups
