Memes and their Meaning for the Study of Adult Learners: Civic Engagement in Chilean For-Profit Graduate Education
The civic engagement commitment and mission among the growing number of forprofit higher education enterprises remains empirically unexplored. Spiral Dynamic Theory (SDT) is proposed as a theoretical framework to examine levels of civic engagement in complex contexts associated with private for-profit, graduate-level education
Bifurcated polarization rotation in bismuth-based piezoelectrics
ABO3 perovskite-type solid solutions display a large variety of structural and physical properties, which can be tuned by chemical composition or external parameters such as temperature, pressure, strain, electric, or magnetic fields. Some solid solutions show remarkably enhanced physical properties including colossal magnetoresistance or giant piezoelectricity. It has been recognized that structural distortions, competing on the local level, are key to understanding and tuning these remarkable properties, yet, it remains a challenge to experimentally observe such local structural details. Here, from neutron pair-distribution analysis, a temperature-dependent 3D atomic-level model of the lead-free piezoelectric perovskite Na0.5Bi0.5TiO3 (NBT) is reported. The statistical analysis of this model shows how local distortions compete, how this competition develops with temperature, and, in particular, how different polar displacements of Bi3+ cations coexist as a bifurcated polarization, highlighting the interest of Bi-based materials in the search for new lead-free piezoelectrics
Teachers Who Left the Teaching Profession: A Qualitative Understanding
In this study, the researchers investigated public school teacher attrition in the State of Texas. The study examined the problem by focusing on the predominant reasons teachers give for leaving the profession after working only one year as a teacher. Eight persons who had left the teaching profession after one year teaching were contacted and interviewed concerning their reasons for leaving. The three most influential factors found were lack of administrative support, difficulties with student discipline, and low salary levels. Study findings and implications for policy are discussed
A Quantitative Correlational Study on Diversity Management, Career Planning, and Career Advancement for Women
Gender disparity is a pervasive problem in the United States automotive industry particularly in critical decision-making positions where male employees dominate the field. Three significant issues were addressed in this study: Diversity management, career planning, and women’s career advancement. The quantitative correlational study investigated how diversity management and career planning are related to women’s advancement in the US automotive industry to improve the representation of women in management and senior-level positions. The gender gap in management was examined through the organizational justice theory and grounded by the glass ceiling metaphor. Ninety-two full-time employees from an automotive company in Atlanta participated through Survey Monkey. Perceived Facilitators to Career Advancement Scales, the Perceived Barriers to Career Advancement Scales, and the Job Descriptive Index Scales were analyzed using multiple regression. The research questions addressed the individual and combined relationship between diversity management and career planning to career advancement
Supporting play exploration and early developmental intervention versus usual care to enhance development outcomes during the transition from the neonatal intensive care unit to home: a pilot randomized controlled trial
Background While therapy services may start in the Neonatal Intensive Care Unit (NICU) there is often a gap in therapy after discharge. Supporting Play Exploration and Early Development Intervention (SPEEDI) supports parents, helping them build capacity to provide developmentally supportive opportunities starting in the NICU and continuing at home. The purpose of this single blinded randomized pilot clinical trial was to evaluate the initial efficacy of SPEEDI to improve early reaching and exploratory problem solving behaviors. Methods Fourteen infants born very preterm or with neonatal brain injury were randomly assigned to SPEEDI or Usual Care. The SPEEDI group participated in 5 collaborative parent, therapist, and infant interventions sessions in the NICU (Phase 1) and 5 at home (Phase 2). Parents provided daily opportunities designed to support the infants emerging motor control and exploratory behaviors. Primary outcome measures were assessed at the end of the intervention, 1 and 3 months after the intervention ended. Reaching was assessed with the infant supported in an infant chair using four 30 s trials. The Early Problem Solving Indicator was used to evaluate the frequency of behaviors during standardized play based assessment. Effect sizes are including for secondary outcomes including the Test of Infant Motor Performance and Bayley Scales of Infant and Toddler Development. Results No group differences were found in the duration of toy contact. There was a significant group effect on (F1,8 = 4.04, p = 0.08) early exploratory problem-solving behaviors with infants in the SPEEDI group demonstrating greater exploration with effect sizes of 1.3, 0.6, and 0.9 at the end of the intervention, 1 and 3 months post-intervention. Conclusions While further research is needed, this initial efficacy study showed promising results for the ability of SPEEDI to impact early problem solving behaviors at the end of intervention and at least 3 months after the intervention is over. While reaching did not show group differences, a ceiling effect may have contributed to this finding. This single blinded pilot RCT was registered prior to subject enrollment on 5/27/14 at ClinicalTrials.Gov with number NCT02153736
Imaging Sources with Fast and Slow Emission Components
We investigate two-proton correlation functions for reactions in which fast
dynamical and slow evaporative proton emission are both present. In such cases,
the width of the correlation peak provides the most reliable information about
the source size of the fast dynamical component. The maximum of the correlation
function is sensitive to the relative yields from the slow and fast emission
components. Numerically inverting the correlation function allows one to
accurately disentangle fast dynamical from slow evaporative emission and
extract details of the shape of the two-proton source.Comment: 13 pages, 4 figure
Diversity Management, Career Planning, and Career Advancement for Women
Gender disparity in the United States automotive industry is a pervasive problem, and the most significant gender gap is in critical decision-making positions. This study addressed diversity management, career planning, and women’s career advancement in the United States automotive industry. The quantitative correlational study aimed to investigate how diversity management and career planning are related to women’s advancement in the United States automotive industry to improve the representation of women in management and senior-level positions. The gender gap in management was examined through the organizational justice theory and grounded by the glass ceiling metaphor. The sample was 92 full-time employees of a mid-Atlantic region automotive company. Data were collected through SurveyMonkey using the Perceived Facilitators to Career Advancement Scales, the Perceived Barriers to Career Advancement Scales, and the Job Descriptive Index Scales. Multiple regression analysis was used to analyze the data. The research questions addressed the individual and combined relationship between diversity management and career planning to career advancement. The results indicated a significant relationship between the linear combination of diversity management and career planning to the advancement of women. The individual relationship between career planning and career advancement was found to be significant. However, there was no significant relationship between diversity management and career advancement. The implication for positive social change is that the study provided collective baseline data on the women’s advancement in the automotive industry. As a result, this study expands current knowledge about women in male-dominated industries in the United States
Intentional Self Regulation and Positive Youth Development: Implications for Youth Development Programs
Character education programs are mission-aligned with the positive youth development (PYD) perspective, which, in research with American youth suggests that intentional self-regulation (ISR) develops through mutually beneficial interactions between youth and their environment. Cross-cultural studies of Western youth suggest an adolescence-specific ISR process may exist. We begin to extend this work to assess the relationship between ISR and positive development in young Scottish adolescents (approximately 7th grade, N = 82; 50% male), a previously unexamined group. ISR was correlated with the Five Cs of PYD and OLS regression analyses demonstrated that ISR predicted two of the Five Cs: Character and Connection. We discuss implications for youth development programs of the findings that ISR and some indices of PYD were linked in a sample of Scottish youth
Age validation of quillback rockfish (Sebastes maliger) using bomb radiocarbon
Rockfishes (Sebastes spp.) support one of the most economically important f isheries of the Pacific Northwest and it is essential for sustainable management that age estimation procedures be validated for these species. Atmospheric testing of thermonuclear devices during the
1950s and 1960s created a global radiocarbon (14C) signal in the ocean environment that scientists have identified
as a useful tracer and chronological marker in natural systems. In this study, we first demonstrated that fewer samples are necessary for age validation using the bomb-generated 14C signal by emphasizing the utility of the time-specific marker created by the initial rise of bomb-14C. Second, the bomb-generated 14C signal retained in fish otoliths was used to validate the age and age estimation method of the quillback rockfish (Sebastes maliger) in the
waters of southeast Alaska. Radiocarbon values from the first year’s growth of quillback rockfish otoliths were plotted against estimated birth year to produce a 14C time series spanning 1950 to 1985. The initial rise in bomb-14C from prebomb levels (~ –90‰) occurred in 1959 [±1 year]
and 14C levels rose relatively rapidly to peak Δ14C values in 1967 (+105.4‰) and subsequently declined through the end of the time series in 1985 (+15.4‰). The agreement between the year of initial rise of 14C levels from the quillback rockfish time series and the chronology determined for the waters of southeast Alaska from yelloweye rockfish (S. ruberrimus) otoliths validated the aging method for the quillback rockfish. The concordance of the entire quillback rockfish 14C time series with the yelloweye rockfish time series demonstrated the effectiveness of this age validation
technique, confirmed the longevity of the quillback rockfish up to a minimum of 43 years, and strongly confirms higher age estimates of u
