Leadership and the Boy Scouts of America's High Adventure Program

Recreation programs for youth are increasingly being asked to justify their purpose beyond providing fun and games. Stakeholders (e.g., taxpayers, parents, or donors) expect youth programs to develop specific outcomes in young people that will assist them in becoming fully functional adults. More empirical evidence is needed to support the idea that recreational programs indeed provide added educational or developmental benefits. One key outcome that transcends many recreational programs, regardless of setting, is leadership development. Therefore, the purpose of this study was to evaluate leadership development in a Boy Scouts of America (BSA) High Adventure Program. Two research objectives guided this study. First, the researcher sought to determine whether youth participants in Philmont’s 12-Day Trek High Adventure Program reported increases in leadership measures as a result of their experiences. Based on the goals of this program, the researcher hypothesized that self-reported leadership qualities would increase after youth had participated in the program. Second, the study went one step further to explore what characteristics of the High Adventure Program potentially promoted or detracted from leadership development within the BSA High Adventure Program. The research design for this study was a non-experimental retrospective research design using quantitative and qualitative data obtained from a single sample of participants at the Philmont Scout Ranch. The method of data collection employed a self-administered survey instrument given to participants upon completion of their program. The survey used the Youth Leadership Life Skills Development Scale in addition to two open-ended questions designed to extract elements that promoted or detracted from leadership development. Results from the Youth Leadership Life Skills Development Scale indicated that there was a statistically significant difference between the mean of participant attitudes before the Philmont experience and the mean of participant attitudes after the Philmont experience. Results from the open-ended questions isolated nine emergent themes that participants reported to promote leadership development and four that detracted from leadership development. Overall, this study provides much needed empirical evidence to contribute to the idea that recreational youth programs, while providing fun leisure experiences, can utilize their settings to make an even bigger contribution to the lives of young people

The real-world implications of an imaginary world: A netnography of a Harry Potter based virtual community (Hogwarts Running Club)

The rapid development, growth, and diffusion of technology throughout the world today has spurred an integration with socializing and engagement that is fast becoming a part of everyday life (Baym, 2015; Blank, 2012; Consalvo & Ess, 2011). One such manifestation of this new form of social interaction is communities formed online or virtual communities (Ridings, Gefen, & Arinze, 2002). Virtual communities have been in existence for over thirty years (Ridings, Gefen, and Arinze, 2002) and existing studies of these communities have yielded powerful insights into learning, communication, marketing, relationships, benefits of participation, and more (Hiltz & Wellman, 1997; Mamonov, Koufaris, & Benbunan-Fich, 2016; Nimrod, 2014; Welbourne, Blanchard, & Boughton, 2009; Wellman & Gulia, 1999; Winkelman & Choo, 2003). However, there are still aspects of virtual communities about which little is known. Therefore, this study utilized the qualitative research technique of Netnography (Kozinets, 2010; 2015) to explore the experiences of participation in a virtual community and the meanings participants associate with membership in this group. Specific research questions focused on motivations, potential benefits, and potential implications for participants’ offline reality. The Hogwarts Running Club (HRC), a virtual community established in 2014 (HRC, 2017), on Facebook was the study setting. This Facebook group had approximately 16,000 members who engaged in online discussions and activities that focused around the Harry Potter book series and running (HRC, 2018a). The posts within the virtual community Great Hall (named for a location that is significant in the Harry Potter book series) served as the source of study data. As the researcher was a member of the HRC, four qualitative techniques were utilized to alleviate concerns surrounding “backyard” research (Glesne & Peshkin, 1992). These four techniques were member checking (Lincoln & Guba, 1985), prolonged engagement in the study setting (Creswell & Miller, 2000; Lincoln & Guba, 1985), peer debriefing (Creswell, 2009; Lincoln & Guba, 1985), and reflexive journaling (Genoe & Liechty, 2016; Walsh, 2003). Findings of the study have been presented as three manuscripts with unique foci. Sense of Community (McMillan & Chavis, 1986), Serious Leisure (Stebbins, 2007; 2012), and benefits and motivations each serve as the focus of a manuscript where implications for research and application have been discussed

Influence of biological matrix and artificial electrospun scaffolds on proliferation, differentiation and trophic factor synthesis of rat embryonic stem cells.

Abstract Two-dimensional vs three-dimensional culture conditions, such as the presence of extracellular matrix components, could deeply influence the cell fate and properties. In this paper we investigated proliferation, differentiation, survival, apoptosis, growth and neurotrophic factor synthesis of rat embryonic stem cells (RESCs) cultured in 2D and 3D conditions generated using Cultrex® Basement Membrane Extract (BME) and in poly-( l -lactic acid) (PLLA) electrospun sub-micrometric fibres. It is demonstrated that, in the absence of other instructive stimuli, growth, differentiation and paracrine activity of RESCs are directly affected by the different microenvironment provided by the scaffold. In particular, RESCs grown on an electrospun PLLA scaffolds coated or not with BME have a higher proliferation rate, higher production of bioactive nerve growth factor (NGF) and vascular endothelial growth factor (VEGF) compared to standard 2D conditions, lasting for at least 2 weeks. Due to the high mechanical flexibility of PLLA electrospun scaffolds, the PLLA/stem cell culture system offers an interesting potential for implantable neural repair devices

Model independent measurements of Standard Model cross sections with Domain Adaptation

With the ever growing amount of data collected by the ATLAS and CMS experiments at the CERN LHC, fiducial and differential measurements of the Higgs boson production cross section have become important tools to test the standard model predictions with an unprecedented level of precision, as well as seeking deviations that can manifest the presence of physics beyond the standard model. These measurements are in general designed for being easily comparable to any present or future theoretical prediction, and to achieve this goal it is important to keep the model dependence to a minimum. Nevertheless, the reduction of the model dependence usually comes at the expense of the measurement precision, preventing to exploit the full potential of the signal extraction procedure. In this paper a novel methodology based on the machine learning concept of domain adaptation is proposed, which allows using a complex deep neural network in the signal extraction procedure while ensuring a minimal dependence of the measurements on the theoretical modelling of the signal.Comment: 16 pages, 10 figure

A Randomized Controlled Clinical Trial in Healthy Older Adults to Determine Efficacy of Glycine and N-Acetylcysteine Supplementation on Glutathione Redox Status and Oxidative Damage.

Glycine and cysteine are non-essential amino acids that are required to generate glutathione, an intracellular tripeptide that neutralizes reactive oxygen species and prevents tissue damage. During aging glutathione demand is thought to increase, but whether additional dietary intake of glycine and cysteine contributes towards the generation of glutathione in healthy older adults is not well understood. We investigated supplementation with glycine and n-acetylcysteine (GlyNAC) at three different daily doses for 2 weeks (low dose: 2.4 g, medium dose: 4.8 g, or high dose: 7.2 g/day, 1:1 ratio) in a randomized, controlled clinical trial in 114 healthy volunteers. Despite representing a cohort of healthy older adults (age mean = 65 years), we found significantly higher baseline levels of markers of oxidative stress, including that of malondialdehyde (MDA, 0.158 vs. 0.136 µmol/L, p < 0.0001), total cysteine (Cysteine-T, 314.8 vs. 276 µM, p < 0.0001), oxidized glutathione (GSSG, 174.5 vs. 132.3 µmol/L, p < 0.0001), and a lower ratio of reduced to oxidized glutathione (GSH-F:GSSG) (11.78 vs. 15.26, p = 0.0018) compared to a young reference group (age mean = 31.7 years, n = 20). GlyNAC supplementation was safe and well tolerated by the subjects, but did not increase levels of GSH-F:GSSG (end of study, placebo = 12.49 vs. 7.2 g = 12.65, p-value = 0.739) or that of total glutathione (GSH-T) (end of study, placebo = 903.5 vs. 7.2 g = 959.6 mg/L, p-value = 0.278), the primary endpoint of the study. Post-hoc analyses revealed that a subset of subjects characterized by high oxidative stress (above the median for MDA) and low baseline GSH-T status (below the median), who received the medium and high doses of GlyNAC, presented increased glutathione generation (end of study, placebo = 819.7 vs. 4.8g/7.2 g = 905.4 mg/L, p-value = 0.016). In summary GlyNAC supplementation is safe, well tolerated, and may increase glutathione levels in older adults with high glutathione demand.

Higher education teachers' experiences with learning analytics in relation to student retention

This paper presents findings from a study of Australian and New Zealand academics (n = 276) that teach tertiary education students. The study aimed to explore participants’ early experiences of learning analytics in a higher education milieu in which data analytics is gaining increasing prominence. Broadly speaking participants were asked about: (1) Their teaching context, (2) Their current student retention activities, (3) Their involvement in, and aspirations for, learning analytics use, (4) Their relationship with their institution around learning analytics. The sampled teaching staff broadly indicated a high level of interest but limited level of substantive involvement in learning analytics projects and capacity building activities. Overall, the intention is to present a critical set of voices that assist in identifying and understanding key issues and draw connections to the broader work being done in the field

Accounting students' IT applicaton skills over a 10-year period

This paper reports on the changing nature of a range of information technology (IT) application skills that students declare on entering an accounting degree over the period from 1996 to 2006. Accounting educators need to be aware of the IT skills students bring with them to university because of the implications this has for learning and teaching within the discipline and the importance of both general and specific IT skills within the practice and craft of accounting. Additionally, IT skills constitute a significant element within the portfolio of employability skills that are increasingly demanded by employers and emphasized within the overall Higher Education (HE) agenda. The analysis of students' reported IT application skills on entry to university, across a range of the most relevant areas of IT use in accounting, suggest that their skills have continued to improve over time. However, there are significant differential patterns of change through the years and within cohorts. The paper addresses the generalizability of these findings and discusses the implications of these factors for accounting educators, including the importance of recognising the differences that are potentially masked by the general increase in skills; the need for further research into the changing nature, and implications, of the gender gap in entrants' IT application skills; and the low levels of entrants' spreadsheet and database skills that are a cause for concern

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

Beam test performance of a prototype module with Short Strip ASICs for the CMS HL-LHC tracker upgrade

The Short Strip ASIC (SSA) is one of the four front-end chips designed for the upgrade of the CMS Outer Tracker for the High Luminosity LHC. Together with the Macro-Pixel ASIC (MPA) it will instrument modules containing a strip and a macro-pixel sensor stacked on top of each other. The SSA provides both full readout of the strip hit information when triggered, and, together with the MPA, correlated clusters called stubs from the two sensors for use by the CMS Level-1 (L1) trigger system. Results from the first prototype module consisting of a sensor and two SSA chips are presented. The prototype module has been characterized at the Fermilab Test Beam Facility using a 120 GeV proton beam

Selection of the silicon sensor thickness for the Phase-2 upgrade of the CMS Outer Tracker

During the operation of the CMS experiment at the High-Luminosity LHC the silicon sensors of the Phase-2 Outer Tracker will be exposed to radiation levels that could potentially deteriorate their performance. Previous studies had determined that planar float zone silicon with n-doped strips on a p-doped substrate was preferred over p-doped strips on an n-doped substrate. The last step in evaluating the optimal design for the mass production of about 200 m$^{2}$ of silicon sensors was to compare sensors of baseline thickness (about 300 μm) to thinned sensors (about 240 μm), which promised several benefits at high radiation levels because of the higher electric fields at the same bias voltage. This study provides a direct comparison of these two thicknesses in terms of sensor characteristics as well as charge collection and hit efficiency for fluences up to 1.5 × 10$^{15}$ n$_{eq}$/cm$^{2}$. The measurement results demonstrate that sensors with about 300 μm thickness will ensure excellent tracking performance even at the highest considered fluence levels expected for the Phase-2 Outer Tracker
