Situation awareness measurement: A review of applicability for C4i environments

The construct of situation awareness (SA) has become a core theme within the human factors (HF) research community. Consequently, there have been numerous attempts to develop reliable and valid measures of SA but there is a lack of techniques developed specifically for the assessment of SA in command, control, communication, computers and intelligence (C4i) environments. During the design, development and evaluation of novel systems, technology and procedures, valid and reliable situation awareness measurement techniques are required for the assessment of individual and team SA, in order to determine the improvements (or in some cases decrements) resulting from proposed design and technological interventions. The paper presents a review of existing situation awareness measurement techniques for their suitability for use in the assessment of SA in C4i environments. Seventeen SA measures were evaluated against a set of HF methods criteria. It was concluded that current SA measurement techniques are inadequate by themselves for use in the assessment of SA in C4i environments, and a multiple-measure approach utilising different approaches is recommended

In the Groove: A Documentary about Vinyl

The goal of this thesis project, ‘In the Groove’ is to tell the story of why vinyl records, a music format written off as a casualty to the digital age is experiencing a cultural resurgence. In the last several years vinyl records have been the only musical format to record positive sales growth. For many musicians today, pressing their music to vinyl records yields the greatest return on investment. However, vinyl remains a niche market, supported by a devoted fan base. This film focuses on a group of artists and vinyl enthusiasts as they navigate this new marketplace

The [OIII]++Hβ\beta Equivalent Width Distribution at z≃\simeq7: Implications for the Contribution of Galaxies to Reionization

We quantify the distribution of [OIII]+H$\beta$ line strengths at z$\simeq$7 using a sample of 20 bright (M$_{\mathrm{UV}}$ $\lesssim$ $-$21) galaxies. We select these systems over wide-area fields (2.3 deg$^2$ total) using a new colour-selection which precisely selects galaxies at z$\simeq$6.63$-$6.83, a redshift range where blue Spitzer/IRAC [3.6]$-$[4.5] colours unambiguously indicate strong [OIII]$+$H$\beta$ emission. These 20 galaxies suggest a log-normal [OIII]$+$H$\beta$ EW distribution with median EW = 759$^{+112}_{-113}$ $\mathrm{\mathring{A}}$ and standard deviation = 0.26$^{+0.06}_{-0.05}$ dex. We find no evidence for strong variation in this EW distribution with UV luminosity. The typical [OIII]+H$\beta$ EW at z$\simeq$7 implied by our sample is considerably larger than that in massive star forming galaxies at z$\simeq$2, consistent with a shift toward larger average sSFR (4.4 Gyr$^{-1}$) and lower metallicities (0.16 Z$_\odot$). We also find evidence for the emergence of a population with yet more extreme nebular emission ([OIII]+H$\beta$ EW$>$1200 $\mathrm{\mathring{A}}$) that is rarely seen at lower redshifts. These objects have extremely large sSFR ($>$30 Gyr$^{-1}$), as would be expected for systems undergoing a burst or upturn in star formation. While this may be a short-lived phase, our results suggest that 20% of the z$\simeq$7 population has such extreme nebular emission, implying that galaxies likely undergo intense star formation episodes regularly at z$>$6. We argue that this population may be among the most effective ionizing agents in the reionization era, both in terms of photon production efficiency and escape fraction. We furthermore suggest that galaxies passing through this large sSFR phase are likely to be very efficient in forming bound star clusters.Comment: 20 pages, 11 figures.

Does Experiential Learning Add Value in Financial Literacy Education: A Qualitative Investigation

According to Marketwatch.com the lack of financial literacy among U.S. citizens has cost upwards of $200 billion over the last twenty years. Besides racking up student loan debt that averaged about$37,172 per student in 2016 (Marketwatch.com) millennials and those in Generation Z are also the most likely to engage in risky financial behaviors like payday loans, pawnshops and tax refund advances (PwC, 2016; Mottolla, 2014). Being financially vulnerable as young adults compounded with today’s increasingly complex financial environment (Batty et al., 2015), make fertile ground for mistakes that have lifelong impact. Over the last 20 years, much has been done to better educate students so that they can be financially capable adults. Many states have mandated financial literacy education before high school graduation and there is no lack of programs dedicated to getting students more financially prepared for the real world. Despite all of these efforts, financial knowledge scores of young adults have remained the same (Friedline & West, 2016). At the heart of this study was finding a high impact way to teach financial literacy. This study’s purpose was to examine whether experiential education added value to a financial literacy program. Focus groups were used to explore whether fifth graders had more positive attitudes, increased interest and motivation and greater feelings of self-efficacy after the experiential portion of a financial literacy program, Junior Achievement BizTown
