Social Networks in Higher Education: A Study of the Relationship of Social Structural and Proximity Factors to Teacher Credibility and Perceived Quality of Academic Life

As Berge (1998) tells us, learning is a lifelong process that is important to effective participation in cultural and economic life in a democratic society. In their research on cultural issues in distance education, Enoch and Soker (2006) note one of the major concerns of modern societies today is to ensure increased access to higher education, and to include members of formerly under-represented social groups and categories, such as ethnic and racial minorities, women and people who live in distant rural or disadvantaged areas or who have to combine their studies with full-time or part-time jobs. Building on the work of Enoch and Soker, this paper looks at race, gender, age, course lcoation and job status and their relationship to teacher credibility and perceived quality of academic life. The data for this study was provided by students attending a community college located in a metropolitan area of the Midwest

Empowering Non-Traditional Students to Succeed in Online Programs

In their research on student learning Rieh and Hilligoss (2008) study the proximal factors of today’s students and how they interact with technology, in their pursuit of information. This paper looks at how race, age and job status are related to students’ perception of their in

Student Engagement: A Study of the Relationship between Teacher Credibility and Student Self-Efficacy

Given the current economic and subsequent employment uncertainty, people are returning to college to update their skills and acquire the credentials they need to be competitive in today\u27s workforce. As a result, faculty must be prepared to facilitate the learning process for an ever-changing and more diverse student body. The purpose of this research is to further the extant body of research in the area of effective student engagement. The variables being used to represent credibility are competence, goodwill and trustworthiness. They were measured using McCroskey and Teven\u27s (1999) Source Credibility Questionnaire. The data for this study were provided by students attending a community college located in the metropolitan area of a Midwestern city. Using competence, trustworthiness and goodwill as the antecedents to represent instructor credibility, this research tests the relationship between instructor credibility and student self-efficacy. Conducting a study of this type will provide faculty and administrators looking for new approaches to teacher leadership with data to help them enhance student engagement and increase their rate of persistence to graduation

Analyzing Critical Factors: Motivating Project Managers

The concept of project management has evolved tremendously over the years. In addition to the technostructure changes that have taken place, the recent pandemic and sociocultural events and subsequent reflection that has occurred have impacted how people live and work. The purpose of this research study was to investigate the factors that create a culture of modern-day multigenerational project managers to be fully emotionally engaged when managing and leading organization projects. One hundred twenty practicing project managers working in a variety of industries representing different countries were interviewed. The findings identify the top six most frequently cited factors. The paper then explores ways to assist organizational leaders in design work environments that support modern-day multigenerational project managers to be fully emotionally engaged when managing and leading organization projects

Issues and progress in the prediction of ocean submesoscale features and internal waves

Data-constrained dynamical ocean modeling for the purpose of detailed forecasting and prediction continues to evolve and improve in quality. Modeling methods and computational capabilities have each improved. The result is that mesoscale phenomena can be modeled with skill, given sufficient data. However, many submesoscale features are less well modeled and remain largely unpredicted from a deterministic event standpoint, and possibly also from a statistical property standpoint. A multi-institution project is underway with goals of uncovering more of the details of a few submesoscale processes, working toward better predictions of their occurrence and their variability. A further component of our project is application of the new ocean models to ocean acoustic modeling and prediction. This paper focuses on one portion of the ongoing work: Efforts to link nonhydrostatic-physics models of continental-shelf nonlinear internal wave evolution to data-driven regional models. Ocean front-related effects are also touched on.United States. Office of Naval Research (United States. Dept. of Defense.

Influence of sex, migration distance, and latitude on life history expression in steelhead and rainbow trout (Oncorhynchus mykiss)

In partially migratory species, such as Oncorhynchus mykiss, the emergence of life history phenotypes is often attributed to fitness trade-offs associated with growth and survival. Fitness trade-offs can be linked to reproductive tactics that vary between the sexes, as well as the influence of environmental conditions. We found that O. mykiss outmigrants are more likely to be female in nine populations throughout western North America (grand mean 65% female), in support of the hypothesis that anadromy is more likely to benefit females. This bias was not related to migration distance or freshwater productivity, as indicated by latitude. Within one O. mykiss population we also measured the resident sex ratio and did not observe a male bias, despite a high female bias among outmigrants in that system. We provide a simulation to demonstrate the relationship between sex ratios and the proportion of anadromy and show how sex ratios could be a valuable tool for predicting the prevalence of life history types in a population

Field and laboratory validation of remote rover operations Science Team findings: The CanMars Mars Sample Return analogue mission

The CanMars Mars Sample Return Analogue Deployment (MSRAD) was a closely simulated, end-to-end Mars Sample Return (MSR) mission scenario, with instrumentation, goals, and constraints modeled on the upcoming NASA Mars 2020 rover mission; this paper reports on the post-mission validation of the exercise. The exercise utilized the CSA Mars Exploration Science Rover (MESR) rover, deployed to Utah, USA, at a Mars-analogue field site. The principal features of the field site located near Green River, Utah are Late Jurassic inverted, fluvial paleochannels, analogous to features on Mars in sites being considered for the ESA ExoMars rover mission and present within the chosen landing site for the Mars 2020 rover mission. The in-simulation (“in-sim”) mission operations team worked remotely from The University of Western Ontario, Canada. A suite of MESR-integrated and hand-held spectrometers was selected to mimic those of the Mars 2020 payload, and a Utah-based, on-site team was tasked with field operations to carry out the data collection and sampling as commanded by the in-sim team. As a validation of the in-sim mission science findings, the field team performed an independent geological assessment. This paper documents the field team's on-site geological assessment and subsequent laboratory and analytical results, then offers a comparison of mission (in-sim) and post-mission (laboratory) science results. The laboratory-based findings were largely consistent with the in-sim rover-derived data and geological interpretations, though some notable exceptions highlight the inherent difficulties in remote science. In some cases, available data was insufficient for lithologic identification given the absence of other important contextual information (e.g., textural information). This study suggests that the in-sim instruments were largely adequate for the Science Team to characterize samples; however, rover-based field work is necessarily hampered by mobility and time constraints with an obvious effect on efficiency but also precision, and to some extent, accuracy of the findings. The data show a dearth of preserved total organic carbon (TOC) – used as a proxy for ancient biosignature preservation potential – in the fluvial-lacustrine system of this field site, suggesting serious consideration with respect to the capabilities and opportunities for addressing the Mars exploration goals. We therefore suggest a thorough characterization of terrestrial sites analogous to those of Mars rover landing sites, and in-depth field studies like CanMars as important, pre-mission strategic exercises

Herschel Exploitation of Local Galaxy Andromeda (HELGA) III: The Star Formation Law in M31

We present a detailed study of how the Star Formation Rate (SFR) relates to the interstellar medium (ISM) of M31 at ~140pc scales. The SFR is calculated using the far-ultraviolet and 24um emission, corrected for the old stellar population in M31. We find a global value for the SFR of 0.25+/-0.05Msun/yr and compare this with the SFR found using the total far-infrared (FIR) luminosity. There is general agreement in regions where young stars dominate the dust heating. Atomic hydrogen (HI) and molecular gas (traced by carbon monoxide, CO) or the dust mass is used to trace the total gas in the ISM. We show that the global surface densities of SFR and gas mass place M31 amongst a set of low-SFR galaxies in the plot of Kennicutt (1998b). The relationship between SFR and gas surface density is tested in six radial annuli across M31, assuming a power law relationship with index, N. The star formation law using total gas traced by HI and CO gives a global index of N=2.03+/-0.04, with a significant variation with radius; the highest values are observed in the 10kpc ring. We suggest that this slope is due to HI turning molecular at ~10Msun/pc2. When looking at H2 regions, we measure a higher mean SFR suggesting a better spatial correlation between H2 and SF. We find N~0.6 with consistent results throughout the disk - this is at the low end of values found in previous work and argues against a superlinear SF law on small scales.Comment: 12 pages, 10 figure
