The relationships between personality, approaches to learning, and academic success in first-year psychology distance education students

[Abstract]: The first aim of this study was to examine the relationships between the big five personality traits and approaches to learning in a sample of first-year psychology distance students. Approaches to learning are the intentions a student has when faced with a learning task. A deep approach reflects an intention to understand the material, a strategic approach reflects an intention to achieve the highest grades possible, and a surface approach reflects an intention to cope with the course requirements by memorising facts. Consistent with previous research of on-campus students, the Intellect trait predicted the deep learning approach; the Conscientiousness trait predicted the strategic learning approach; and the Emotional Stability trait negatively predicted the surface learning approach. The second aim of this study was to investigate whether approaches to learning predict academic success, as measured by grade point average. As expected, the surface learning approach negatively predicted achievement. However, contrary to expectations, neither the deep nor the strategic learning approach predicted academic success. This finding may partly be explained by these first-year distance students undergoing a transition to the expectations and requirements of their flexible learning environments. Further research is warranted to establish whether the deep and strategic learning approaches become more likely to predict academic success in the latter years of study, after distance students have adapted to the flexible delivery methods. To this end, a longitudinal study that tracks the academic performance of these students until they complete their degrees or leave the university is recommended

HI Observations Towards the Sagittarius Dwarf Spheroidal Galaxy

We have measured the 21-cm line of Galactic HI over more than 50 square degrees in the direction of the Sagittarius dwarf spheroidal galaxy. The data show no evidence of HI associated with the dwarf spheroidal which might be consider analogous to the Magellanic Stream as it is associated in both position and velocity with the Large Magellanic Cloud. Nor do the HI data show evidence for any disturbance in the Milky Way disk gas that can be unambiguously assigned to interaction with the dwarf galaxy. The data shown here limit the HI mass at the velocity of the Sagittarius dwarf to <7000 solar masses over some 18 square degrees between Galactic latitudes -13 degrees and -18 degrees.Comment: 5 pages, 4 figures; accepted for publication in Astronomy & Astrophysic

Quasi-static granular flow of ice mélange

We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier. Winter velocity fields are generally steady and highly uniform. Summer velocity fields, on the other hand, tend to be much more variable and can be uniform, compressional, or extensional. We rarely observe compressional flow at Jakobshavn Isbræ or extensional flow at Helheim Glacier, while both are observed at Kangerdlugssuaq Glacier. Transverse velocity profiles from all three locations are suggestive of viscoplastic flow, in which deformation occurs primarily in shear zones along the fjord walls. We analyze the transverse profiles in the context of quasi-static flow using continuum rheologies for granular materials and find that the force per unit width that ice mélange exerts on glacier termini increases exponentially with the ice mélange length-to-width ratio and the effective coefficient of friction. Our estimates of ice mélange resistance are consistent with other independent estimates and suggest that ice mélange may be capable of inhibiting iceberg calving events, especially during winter. Moreover, our results provide geophysical-scale support for constitutive relationships for granular materials and suggest a potential avenue for modeling ice mélange dynamics with continuum models.From acknowledgments: Funding for this project was provided by the U.S. National Science Foundation (DMR-1506446 and DMR-1506307).

A study of the understanding of knowledge and learning of a cohort of mature age students

In 2005 the authors began a longitudinal research project to explore the factors that influence student success in the Master of Engineering Practice program which was offered for the first time in Semester 2, 2004. This distance education program enables experienced Engineering Technologists to use their workplace learning to gain a qualification at the Professional Engineer level. This research was initiated because the admission of some students into the program is based on the recognition of their prior workplace learning. Cantwell and Scevak (2004) highlighted the problems that students may encounter when they gain entry to a university on this basis. To explore this issue four previously validated questionnaires were used to gather data on: student approaches to learning, their epistemological beliefs, learning style preferences, and strategic flexibility. This paper reports on a preliminary analysis of the data gathered from the students who enrolled in the program during the period 2005-2009. In the longer term, when the sample size has grown and more students have graduated, the data will be analysed to explore the relationship between the measured factors and success at university

An infrared proper motion study of the Orion bullets

We report the first IR proper motion measurements of the Herbig-Haro objects in the Orion Molecular Cloud--One using a four-year time baseline. The [Fe II] emitting bullets are moving of order 0.08 arcsec per year, or at about 170 \kms. The direction of motion is similar to that inferred from their morphology. The proper motions of \h2 emitting wakes behind the [Fe II] bullets, and of newly found \h2 bullets, are also measured. \h2 bullets have smaller proper motion than [Fe II] bullets, while \h2 wakes with leading [Fe II] bullets appear to move at similar speeds to their associated bullets. A few instances of variability in the emission can be attributed to dense, stationary clumps in the ambient cloud being overrun, setting up a reverse--oriented bullet. Differential motion between [Fe II] bullets and their trailing \h2 wakes is not observed, suggesting that these are not separating, and also that they have reached a steady--state configuration over at least 100 years. The most distant bullets have, on average, larger proper motions, but are not consistent with free expansion. Nevertheless an impulsive, or short--lived ($\ll$ 1,000 years) duration for their origin seems likely.Comment: 9 pages, 8 figure

Emerging spheres of engagement: the role of trust and care in community-university research

Community-engaged research takes place at a complex social site that has both a history and a future as well as encompassing the project activities of the researchers and community members. We argue that a crucial methodological aspect of undertaking such research is the development of trust relationships between researchers and community. We propose that for each research project, this relationship can best be understood as a ‘sphere of engagement’, after Ingold’s ‘sphere of nurture’, and that trust and care are emergent and binding qualities of this sphere. Tracing the development of trust relationships in a case study, using the idea of security-based trust and harmony-based trust, we conclude that trust, and the related concept of care, bind together people, events, histories and futures beyond the dichotomous and time-delimited relationship of a research contract, and carry the sphere of engagement of researchers and community beyond the life of any one project

Good places for ageing in place : development of objective built environment measures for investigating links with older people's wellbeing

Background: There is renewed interest in the role of the built environment in public health. Relatively little research to date investigates its impact on healthy ageing. Ageing in place has been adopted as a key strategy for coping with the challenges of longevity. What is needed is a better understanding of how individual characteristics of older people’s residential environments (from front door to wider neighbourhood) contribute to their wellbeing, in order to provide the basis for evidence-based housing/urban design and development of interventions. This research aimed to develop a tool to objectively measure a large range of built environment characteristics, as the basis for a preliminary study of potential relationships with a number of ‘place-related’ functional, emotional and social wellbeing constructs. Methods: Through a review of urban design literature, design documents, and existing measures, a new tool, the NeDeCC (Neighbourhood Design Characteristics Checklist) was developed. It was piloted, refined, and its reliability validated through inter-rater tests. A range of place-related wellbeing constructs were identified and measured through interviews with 200 older people living in a wide variety of rural-urban environments and different types of housing in England. The NeDeCC was used to measure the residential environment of each participant, and significant bivariate relationships with wellbeing variables were identified. Results: The NeDeCC was found to have convincing face and construct validity and good inter-rater and test/ retest reliability, though it would benefit from use of digital data sources such as Google Earth to eliminate the need for on-site survey. The significant relationships found in the study suggest that there may be characteristics of residential environments of potential relevance for older people’s lives that have been overlooked in research to date, and that it may be worthwhile to question some of the assumptions about where and how older people want to live (e.g. villages seem to be positive). They also point to the importance of considering non-linear relationships. Conclusions: The NeDeCC provides the basis for generation of evidence-based design guidance if it is used in prospective controlled studies or ‘natural experiments’ in the future. Ultimately, this will facilitate the creation of better places for ageing in place

Is Simpler Always Better? Consumer Evaluations of Front-of-Package Nutrition Symbols

Consumers of packaged goods products in the United States recently have faced an onslaught of front-of-package (FOP) nutrition symbols and icons, including the controversial “Smart Choices” single summary indicator. In a between-subjects experiment with 520 adult consumers, the authors compare effects of the Smart Choices (SC) icon, the more complex Traffic Light–Guideline Daily Amounts (TLGDAs) icon, and a no-FOP icon control for a nutritionally moderate food that qualifies for the SC icon. Drawing from principles of heuristic processing and halo effects, the authors predict and find that the SC icon can lead to positive (and potentially misleading) nutrient evaluations and product healthfulness when compared with the TL-GDA icon or no-FOP icon control. When the Nutrition Facts Panel is not available, the TL-GDA icon results in substantially greater nutrition accuracy scores than with the SC icon or control. The authors also find that nutrition consciousness is more likely to moderate effects related to the Nutrition Facts Panel than the FOP nutrition icon information. Implications are offered for public health officials, nutrition researchers, and food manufacturers, as the Food and Drug Administration considers FOP nutrition alternatives for use in the United States
