TAM or VFM? Which Model Matches How People Ascribe Actually Value?

The IT community has a long history of developing theory to explain when people will change their behaviors to adopt new technology systems. Two current technology adoption theories, the Technology Adoption Model and the Value Frequency Model, draw from different groups of referent theory: Reasons Theories (RTs) and Expectancy Value Theories (EVTs). RTs and EVTs make different assumptions about how people form attitudes toward behavioral changes (i.e., to adopt or not). Having a better understanding of how people make judgments that affect their behavioral choices could help guide the choice of referent theory when developing new IT theory. This study examined how people responded to attitude-shaping scenarios as a way to gain insight into the assumptions that could be guiding their choices. Their responses indicated a tendency to assign values in ways consistent with the assumptions and processes articulated in EVTs

Mechanical behavior study of plasma sprayed hydroxyapatite coatings onto Ti6Al4V substrates using scratch test

Mechanical behavior and fracture mechanisms of plasma sprayed hydroxyapatite coatings on Ti-6Al-4V substrate were assessed taking into consideration two variables: the coating thickness and the substrate roughness. The results show that the specimens having a substrate arithmetic average roughness parameter Ra = 2.29 μm is favorable with respect to Ra = 1.23 μm. For coating thickness above 105 μm, cracks can be observed in the coating/substrate interface and the higher critical load Pc2 (used generally in comparative evaluation of adherence) decreases. A 90 μm coating thickness sprayed on a substrate having an arithmetic average roughness parameter Ra equal to 2.29 μm seems to be the best compromise between microstructure, mechanical resistance (high critical loads and fairly good contact quality) and long term stability in the physiological medium (low dissolution rate) for an orthopedic application

Talent Development of Refugee Women

In almost all refugee populations approximately half are women (Martin, 2004; UNHCR, 2014). The United Nations High Commissioner for Refugees (UNHCR) describes refugees as individuals who are forced to migrate to other countries due to war, civil unrest, or fears of persecution. Not only do refugees receive no protection from their own government, it is frequently their own country that has threatened their personal security and freedom. Refugee women face particular challenges when integrating into new communities, especially industrialized countries. Young women may unexpectedly be required to assume the role of caregivers or sole breadwinners when traditional heads of household are unable to learn local languages, or have difficulties adapting to the workforce. Older or single mothers lack the traditional support and friendship networks that extended families provide (Yakushko, 2010). Often unprepared for the new work environment, many refugee women lack sufficient language skills, technological experience, or cultural competence to adequately support a household or even themselves. Past experiences of trauma may exacerbate the difficulties of transition (UNHCR, 2008). Part of claiming a rightful place in the host countries is full participation in society. Women who are alone or who are heads of household must be assisted with the tools and training that will permit them to acquire housing, transportation, healthcare, and other necessities, with the eventual goal of being fully independent and contributing members of their new communities. Preparing for the workforce through talent development is the first step on their journey of independence and empowerment (Yakushko, Backhaus, Watson, Ngaruiya, & Gonzalez, 2008). In this chapter, we will discuss how potential talent can be identified and developed during the critical stage of pre-employment of refugee women resettling in industrialized countries

Core Outcome Measures for Adults with Neurologic Conditions: Pilot Implementation in Hospital-Based Outpatient Clinic.

This residency capstone project’s objective was implementation of 3 of the core neuro outcome measures within a small outpatient clinic, as they were being used inconsistently and heterogeneously. The project included 3 phases: preparation/development, education, and implementation, followed by analyzing and reporting on the project’s and resident’s outcomes

Core Outcome Measures for Adults with Neurologic Conditions: Pilot Implementation in Hospital-Based Outpatient Clinic.

Purpose: To describe a pilot implementation project of 3 of the core neuro outcome measures (OMs) within a small outpatient clinic. Description: OMs provide standardized methods to track patient progress and functional status across levels of care. As the PT profession continues implementing standardized and evidence-based clinical practice guidelines (CPGs) to reflect expertise in the movement system, consistent use of OMs is crucial.1-3 A core set of OMs (COMs) CPG was developed for adults with neurologic conditions; tools to facilitate its use are being produced through the Academy of Neurologic PT (ANPT).4-6 PTs from new grads to clinical specialists should have adequate exposure to COMs and be able to administer them competently.7 Components of DPT education should be upheld once in the clinic. This capstone residency project is helping bridge that gap, bringing didactic and skills training into the clinic to refresh PTs’ OM exposure and facilitate standard and consistent use. Summary of Use: Needs assessment identified that the clinic (10-15 therapists) was not equipped to use COMs according to ANPT recommendations, and OMs were being used inconsistently. However, staff expressed willingness to begin adopting the CPG recommendations. Clinicians were provided ANPT administration guides and electronic medical record (EMR) documentation phrases. To introduce the CPG and COMs, an education session was given emphasizing recommended COM use, standardization of methods and interpretations, and group work for clinical decision-making with certain patient presentations. The session concluded with a departmental discussion on barriers to using OMs and a plan to address them, with the goal for intentional and consistent use beginning with 3 of the COMs. The department was equipped with a binder with laminated copies of ANPT guides, and the clinic was set up to standardize COM administration. For lab training, clinicians were provided copies of the 3 ANPT guides and a competency checklist, and each OM was demonstrated by the resident. During the lab, clinicians role-played alternating as therapist, patient, and observer for each OM to complete the checklist. Next steps of roll-out are currently in progress, beginning with a 5-week period to collect data, followed by data analysis. Implementation of the measures will occur during the 5 weeks, tracking frequency of OM use, documentation in the EMR, and incorporation into the plan of care as collected through a chart audit tool and weekly check-ins. It will also include a subjective pre/post survey to assess clinician learning outcomes and perceptions. Importance to Members: Barriers to OM administration are clinic-wide, and changing practice patterns may often be met with resistance.5,6,8-11 This pilot project may reflect a feasible way to standardize implementation of the COMs into hospital-based outpatient clinics in a way that is not overwhelming to clinicians nor overtly costly to management. This type of standardized OM implementation may also be able to aid in nation-wide outcomes tracking

Genomic epidemiology of the first epidemic wave of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Palestine.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the novel coronavirus responsible for the COVID-19 pandemic, continues to cause a significant public-health burden and disruption globally. Genomic epidemiology approaches point to most countries in the world having experienced many independent introductions of SARS-CoV-2 during the early stages of the pandemic. However, this situation may change with local lockdown policies and restrictions on travel, leading to the emergence of more geographically structured viral populations and lineages transmitting locally. Here, we report the first SARS-CoV-2 genomes from Palestine sampled from early March 2020, when the first cases were observed, through to August of 2020. SARS-CoV-2 genomes from Palestine fall across the diversity of the global phylogeny, consistent with at least nine independent introductions into the region. We identify one locally predominant lineage in circulation represented by 50 Palestinian SARS-CoV-2, grouping with genomes generated from Israel and the UK. We estimate the age of introduction of this lineage to 05/02/2020 (16/01/2020-19/02/2020), suggesting SARS-CoV-2 was already in circulation in Palestine predating its first detection in Bethlehem in early March. Our work highlights the value of ongoing genomic surveillance and monitoring to reconstruct the epidemiology of COVID-19 at both local and global scales

Reply to "Comment on `Lattice determination of Sigma - Lambda mixing' "

In this Reply, we respond to the above Comment. Our computation [Phys. Rev. D 91 (2015) 074512] only took into account pure QCD effects, arising from quark mass differences, so it is not surprising that there are discrepancies in isospin splittings and in the Sigma - Lambda mixing angle. We expect that these discrepancies will be smaller in a full calculation incorporating QED effects.Comment: 5 page

A lattice determination of Sigma - Lambda mixing

Isospin breaking effects in baryon octet (and decuplet) masses are due to a combination of up and down quark mass differences and electromagnetic effects and lead to small mass splittings. Between the Sigma and Lambda this mass splitting is much larger, this being mostly due to their different wavefunctions. However when isospin is broken, there is a mixing between between these states. We describe the formalism necessary to determine the QCD mixing matrix and hence find the mixing angle and mass splitting between the Sigma and Lambda particles due to QCD effects.Comment: 40 pages, 5 figures, published versio
