Beyond the Incidence of Training: Evidence from a National Employers Survey

This paper seeks to provide new insight into how school and post school training investments are linked to employer workplace practices and outcomes using a unique nationally representative survey of establishments in the U.S., the Educational Quality of the Workforce National Employers Survey (EQW-NES). We go beyond simply measuring the incidence of formal or informal training to examine the determinants of the types employers invest in, the relationship between formal school and employer provided training, who is receiving training, the links between investments in physical and human capital, and the impact that human capital investments have on the productivity of establishments. We find that the smallest employers are much less likely to provide formal training programs than employers from larger establishments. Regardless of size, those employers who have adapted some of the practices associated with what have been called `high performance work systems' are more likely to have formal training programs. Employers who have made large investments in physical capital or who have hired workers with higher average education are also more likely to invest in formal training and to train a higher proportion of their workers, especially in the manufacturing sector. There are significant and positive effects on establishment productivity associated with investments in human capital. Those employers who hire better educated workers have appreciably higher productivity. The impact of employer provided training differs according to the nature, timing and location of the employer investments.

Aerosol studies in mid-latitude coastal environments in Australia

The results of the evaluation of several inversion procedures that were used to select one which provides the most accurate atmospheric extinction profiles for small aerosol extinction coefficients (that often predominate in the maritime airmass) are presented. Height profiles of atmospheric extinction calculated by a two component atmospheric solution to the LIDAR equation will be compared with corresponding in-situ extinction profiles based on the size distribution profiles obtained in Western Australia. Values of the aerosol backscatter to extinction ratio obtained from multi-angle LIDAR measurements will be used in this solution

Bulk photonic metamaterial with hyperbolic dispersion

In this work, we demonstrate a self-standing bulk three-dimensional metamaterial based on the network of silver nanowires in an alumina membrane. This constitutes an anisotropic effective medium with hyperbolic dispersion, which can be used in sub-diffraction imaging or optical cloaks. Highly anisotropic dielectric constants of the material range from positive to negative, and the transmitted laser beam shifts both toward the normal to the surface, as in regular dielectrics, and off the normal, as in anisotropic dielectrics with the refraction index smaller than one. The designed photonic metamaterial is the thickest reported in the literature, both in terms of its physical size 1cm x 1cm x 51 mm, and the number of vacuum wavelengths, N=61 at l=0.84 mm.Comment: 6 pages, 4 figur

Neutron spectroscopic factors of Ni isotopes from transfer reactions

177 neutron spectroscopic factors for nickel isotopes have been extracted by performing a systematic analysis of the angular distributions measured from (d,p) transfer reactions. A subset of the extracted spectroscopic factors are compared to predictions of large-basis shell models in the full pf model space using the GXPF1A effective interaction, and the (f5/2, p3/2, p1/2, g9/2) model space using the JJ4PNA interaction. For ground states, the predicted spectroscopic factors using the GXPF1A effective interaction in the full pf model space agree very well with the experimental values, while predictions based on several other effective interactions and model spaces are about 30% higher than the experimental values. For low-energy excited states (<3.5 MeV), the agreement between the extracted spectroscopic factors and shell model calculations is not better than a factor of two.Comment: 18 pages, 4 figures, 2 tables. accepted for publication in PR

Isospin fractionation and isoscaling in dynamical nuclear collisions

Isoscaling is found to hold for fragment yields in the antisymmetrized molecular dynamics (AMD) simulations for collisions of calcium isotopes at 35 MeV/nucleon. This suggests the applicability of statistical considerations to the dynamical fragment emission. The observed linear relationship between the isoscaling parameters and the isospin asymmetry of fragments supports the above suggestion. The slope of this linear function yields information about the symmetry energy in low density region where multifragmentation occurs.Comment: 11 pages, 6 figure

Codesigned Shared Decision-Making Diabetes Management Plan Tool for Adolescents With Type 1 Diabetes Mellitus and Their Parents: Prototype Development and Pilot Test

Background: Adolescents with type 1 diabetes mellitus have difficulty achieving optimal glycemic control, partly due to competing priorities that interfere with diabetes self-care. Often, significant diabetes-related family conflict occurs, and adolescents’ thoughts and feelings about diabetes management may be disregarded. Patient-centered diabetes outcomes may be better when adolescents feel engaged in the decision-making process. Objective: The objective of our study was to codesign a clinic intervention using shared decision making for addressing diabetes self-care with an adolescent patient and parent advisory board. Methods: The patient and parent advisory board consisted of 6 adolescents (teens) between the ages 12 and 18 years with type 1 diabetes mellitus and their parents recruited through our institution’s Pediatric Diabetes Program. Teens and parents provided informed consent and participated in 1 or both of 2 patient and parent advisory board sessions, lasting 3 to 4 hours each. Session 1 topics were (1) patient-centered outcomes related to quality of life, parent-teen shared diabetes management, and shared family experiences; and (2) implementation and acceptability of a patient-centered diabetes care plan intervention where shared decision making was used. We analyzed audio recordings, notes, and other materials to identify and extract ideas relevant to the development of a patient-centered diabetes management plan. These data were visually coded into similar themes. We used the information to develop a prototype for a diabetes management plan tool that we pilot tested during session 2. Results: Session 1 identified 6 principal patient-centered quality-of-life measurement domains: stress, fear and worry, mealtime struggles, assumptions and judgments, feeling abnormal, and conflict. We determined 2 objectives to be principally important for a diabetes management plan intervention: (1) focusing the intervention on diabetes distress and conflict resolution strategies, and (2) working toward a verbalized common goal. In session 2, we created the diabetes management plan tool according to these findings and will use it in a clinical trial with the aim of assisting with patient-centered goal setting. Conclusions: Patients with type 1 diabetes mellitus can be effectively engaged and involved in patient-centered research design. Teens with type 1 diabetes mellitus prioritize reducing family conflict and fitting into their social milieu over health outcomes at this time in their lives. It is important to acknowledge this when designing interventions to improve health outcomes in teens with type 1 diabetes mellitus

Results of 1/4-Scale Experiments. Vapor Simulant And Liquid Jet A Tests

A quarter-scale engineering model of the center wing tank (CWT) of a 747-100 was constructed. This engineering model replicated the compartmentalization, passageways, and venting to the atmosphere. The model was designed to scale the fluid dynamical and combustion aspects of the explosion, not the structural failure of the beams or spars. The effect of structural failure on combustion was examined by using model beams and spars with deliberately engineered weak connections to the main tank structure. The model was filled with a simulant fuel (a mixture of propane and hydrogen) and ignited with a hot wire. The simulant fuel was chosen on the basis of laboratory testing to model the combustion characteristics (pressure rise and flame speed) of Jet A vapor created by a Jet A liquid layer at 50C at an altitude of 13.8 kft. A series of experiments was carried out in this model in order to: (a) investigate combustion in a CWT geometry; and (b) provide guidance to the TWA 800 crash investigation. The results of the experiments were observed with high-speed film, video, and still cameras, fast and slow pressure sensors, thermocouples, photodetectors, and motion sensors. A special pseudo-schlieren system was used to visualize flame propagation within the tank. This report describes the test program, facility, instrumentation, the first 30 experiments, comparisons between experiments, and performance of the instrumentation; then examines the significance of these results to the TWA 800 crash investigation. The key results of this study are: Flame Motion: The motion of flame was dominated by the effects of turbulence created by jetting through the passageways and vent stringers. A very rapid combustion event (lasting 10 to 20 ms) occurred once the flame traveled outside of the ignition bay and interacted with the turbulent flow. Most of the gas within the tank was burned during this rapid event. Compartments: The combustion time decreased with an increasing number of compartments (bays) within the tank. With six bays, combustion took only 100 to 150 ms to be completed from the time of ignition until the end of the rapid combustion phase. The total combustion event was three to four times shorter with compartments than without. Venting: Venting to the outside of the tank through the model vent stringers had a negligible effect on the combustion progress or on the peak pressure reached at the end of the burn. Ignition Location: Variation of the ignition location produced distinctive pressure loads on the structural components. Liquid Fuel: Lofting of a cold liquid fuel layer was produced by the combustion-induced gas motion. Although this spray of liquid eventually ignited and burned, it did not contribute to the pressure loading. Structural Failure: Structural failure resulted in flame acceleration, decreasing the overall combustion time. TWA 800 Investigation: The pressure loads were sufficiently high, up to 4 bar, and the combustion events were sufficiently short, that the forward portion (spanwise beam 3, front spar) of the CWT structure would fail as a direct consequence of the explosion. A combination of pressure loads was produced in some tests consistent with the TWA 800 wreckage. Replica tests, structural modeling, and sensitivity studies on fuel concentration are needed before any conclusions can be drawn about probable ignition locations. Cargo Bay: Tests with a simplified model of a half-full cargo bay indicated that repeated pressure waves with an amplitude of 1 bar or less are produced when an explosion scenario similar to TWA 800 is tested. Future Testing: Future studies should include replica tests, tests with Jet A vapor and warm liquid Jet A layers, and sensitivity tests to examine ignition location, fuel concentration, and vent area perturbations. Summary: Explosion tests in a 747-100 CWT model reveal that a very complex pattern of combustion occurs due the interaction of the flame and the flow-generated turbulence. A wide range of structural load patterns occur, depending on the location of the ignition source. Some of these load patterns are consistent with damage believed to be associated with the initial explosion event in TWA 800. Sensitivity of the loading to the ignition location indicates that narrowing down the ignition location in TWA 800 may be possible. However, the complexity of the combustion and structural failure processes in the actual center wing tank mandates extremely careful consideration of the uncertainties that enter into this process

EMPOWERCARE: EMPOWERing individuals & communities to manage their own CARE

EMPOWERing individuals and communities to manage their own CARE (EMPOWERCARE) was a 3-year social innovation project involving 13 cross border European partners. EMPOWERCARE developed a holistic community asset approach to respond to current gaps in the care of people in the target group (those aged 65+ and those aged 50+ with at least one chronic condition). It aimed to address challenges facing our societies concerning the care of our ageing populations and when older people are not being involved in decisions concerning their own health and wellbeing. The project ensured that older people are at the forefront of improved technology and better care from within their communities. This sought to improve their situation but also tackle the financial issues of an ageing population and improve social cohesion. The main key messages from the evaluation of the project initiatives were: • Self-efficacy – Across all sites, ‘inactive’ participants at baseline showed a statistically significant increase in self-efficacy at the end of the initiatives. Qualitative data confirmed end-users’ increased levels of selfconfidence and self-efficacy around taking action in relation to their own health. • Emotional and social wellbeing - When considering all project sites, there was no significant decrease of the level of reported loneliness, overall and by type (emotional and social), for participants who reported feeling lonely at the start of the initiative. For participants from philosophically focused initiatives, who reported being lonely at the start of the initiative, there was a slight decrease in emotional loneliness from baseline, although this change was not statistically significant. Overall, there was no decrease, but for initiatives that were philosophically focused there was a negative trend. Qualitative data evidenced the positive impact initiatives had in tackling end-users’ loneliness. • Digital literacy - When analysing survey responses from all sites, end-users reported internet healthseeking behaviour did change at the end of initiatives. Nonetheless, for the sites focusing more on technology, internet health-seeking behaviour increased from baseline to end of initiative, although the positive change was not statistically significant. Qualitative data from end-users confirms the survey results that those participating in the initiatives felt more digitally literate and confident in using technology for their physical and mental health needs and to keep connected with their social networks. • Internet health-seeking behaviour – There was no significant change in this area for end-users. This could be explained by them receiving help in-person and therefore they felt less need to go online for help with their health. For technology focused initiatives there was still no significant change, but there was a positive trend for technology enthusiasm. Anxiety around technology use remained and the qualitative data relating to this indicated there was room to build on technology skills. • Person centred care - Across all sites, for those that had a baseline of below average person-centredness or lower, mean scores increased from baseline to end of initiatives, and this improvement was statistically significant, indicating that the project initiatives significantly increased workforce person-centeredness. There were also similar significant improvements in the specific areas of this scale of Climate of Safety, Climate of Everydayness, Climate of community and Climate of Comprehensibility, indicating that the project initiatives significantly increased workforce feelings of whether the workplace is a place where the patients are in safe hands, staff use language that the patients can understand, it is easy for patients to talk to the staff and where the patients have someone to talk to if they so wish. Qualitative data reflected these results, talking about the transformation in people’s lives that was possible through being focused on the needs of the individuals and what matters to them. • Workforce technology uptake - Across all sites, survey results from workforce attitudes towards technology did not show any change from baseline to end of initiatives. Similarly, there was no difference between workforce participants in technology-focused and philosophical initiatives. Qualitative data from the workforce showed an understanding of the need to embrace technology in their work and that some of the drive for that need came from the implementation of COVID-19 restrictions. • Job satisfaction and workforce training embeddedness – for job satisfaction there was no significant change, although there was a positive trend for those who started below the top 15%. The context of working through COVID-19 may have had a negative impact on job satisfaction. Across all sites, there were higher average scores on certain areas of efficacy in relation to workforce training in implementing, embedding, and integrating a complex healthcare initiative, such as reflective monitoring and collective action compared to coherence, and cognitive participation findings suggest that overall workforce members showed they are willing to engage in reflexive monitoring and collective action across all sites – so they were willing to self-monitor and take time to think about their behaviour and work together to take action. The qualitative data indicated that embedding training has enabled the workforce to understand the value of taking time, reflecting and connecting, which are some of the key person-centred competencies and attributes you would want to see in a transformed workforce. The Cost Benefit Analysis showed: • Contingent Valuation Method (CVM) evaluation indicate that individuals are willing to pay (WTP) on average €10.31 per month from their own out of pocket expenses to use and obtain the health benefits and wellbeing effects of participating in the EMPOWERCARE initiatives. • WTP is positively influenced by the value individuals place on the technically focused initiatives, willingness to participate in an alternative initiative along with improvements gained in emotional and social loneliness because of the EMPOWERCARE initiatives. • The WTP estimates defined in this evaluation provide significant insights for decision makers and healthcare commissioners on the value that previous participants place on the services provided through the EMPOWERCARE initiatives in local communities. • Insights from the ‘Good Ancestor’ principles in FGD promotes the deliberation of long-term thinking which can lead to the power of change, reshaping decisions to take account of future generations, while promoting and encouraging sustainability in respect for future generations. The evaluation results provide some positive results on the success of the EMPOWERCARE initiatives across the 4 countries. More analysis has been done per site to understand the different aspects of the EMPOWERCARE Strategy, Workforce Transformation Package and Technology Blueprint that made a positive difference to end-users and members of the workforce. This further analysis will provide a more comprehensive picture of the impact of the EMPOWERCARE initiatives, as well as inform the next stages of work
