Burnout and Engagement in Health Profession Students: The Relationships Between Study Demands, Study Resources and Personal Resources

Burnout has been related to increased suicidal thoughts, lower self-esteem and dropout in university students. Engagement in students, however, has been underexplored. This study uses the Job Demands-Resources (JD-R) model and the Conservational of Resources (COR) model to contribute to the knowledge about burnout and engagement in health profession university students. In particular, the role of personal resources, including psychological flexibility, was examined. Participants were 260 nursing, social work, occupational therapy and psychology students from 10 Australian universities. Regression analyses were used to test the JD-R model with a health profession student sample. The model was extended by including personal resources and testing mediation and moderation hypotheses. Personal resources contributed significant additional variance to the model. Mediation effects of study demands and resources with psychological flexibility were found, while moderation effects were not. The results indicate the validity of the JD-R model in a health profession student population and the important role of personal resources. Further design and evaluation of interventions targeting personal resources and study demands and resources are indicated.
Object relatives made easy: A cross-linguistic comparison of the constraints influencing young children's processing of relative clauses

We present the results from four studies, two corpora and two experimental, which suggest that English- and German-speaking children (3;1–4;9 years) use multiple constraints to process and produce object relative clauses. Our two corpora studies show that children produce object relatives that reflect the distributional and discourse regularities of the input. Specifically, the results show that when children produce object relatives they most often do so with (a) an inanimate head noun, and (b) a pronominal relative clause subject. Our experimental findings show that children use these constraints to process and produce this construction type. Moreover, when children were required to repeat the object relatives they most often use in naturalistic speech, the subject-object asymmetry in processing of relative clauses disappeared. We also report cross-linguistic differences in children's rate of acquisition which reflect properties of the input language. Overall, our results suggest that children are sensitive to the same constraints on relative clause processing as adults.
Holocene Bowhead Whale (Balaena mysticetus) Mortality Patterns in the Canadian Arctic Archipelago

Changes according to elevation in frequencies of naturally stranded bowhead whale ( Balaena mysticetus ) remains on Holocene beaches in the Canadian Arctic Archipelago (CAA) closely parallel previously reported temporal changes in frequencies of independently radiocarbon-dated bowhead remains from these same beaches. Specifically, on the basis of emergence curves determined for 10 localities surveyed in the CAA, stranded whale remains tend to be relatively common in beaches dating to approximately 2500-5500 B.P. and those older than 8000 B.P., but relatively rare in beaches dating to 0-2500 B.P. and 5500-8000 B.P. The former beaches apparently developed primarily during periods of relatively ice-free summer conditions, while the latter developed during periods of relatively pervasive summer sea ice that prevented bowheads from entering the region. Length-based mortality profiles of the stranded whale assemblages suggest that random processes, such as ice entrapment, were responsible for the death of most whales found on these beaches.
Petrology and geochemistry of lunar granite 12032,366-19 and implications for lunar granite petrogenesis

Abstract Apollo 12 sample 12032,366-19 is a 21.3 mg granite fragment that is distinct from any other lunar granite or felsite. It is composed of barian K-feldspar, quartz, sodic plagioclase, hedenbergite, fayalite, and ilmenite, with trace amounts of zirconolite, baddeleyite, apatite, and merrillite. The texture of 12032,366-19 is largely a micrographic intergrowth predominantly of K-feldspar and quartz and, to a lesser extent, plagioclase and quartz. Hedenbergite, fayalite, and ilmenite are present in minor but significant quantities-6.0, 3.1, and 1.7 wt%, respectively-and are scattered throughout the feldsparquartz intergrowths. Trace amounts of Zr-bearing phases are found including zirconolite (0.6 wt%) and baddeleyite (0.04 wt%). Incompatible trace-element concentrations are high in 12032,366-19, particularly the high-field-strength elements, e.g., Zr, Sm, and Th (1500, 25, and 61 μg/g, respectively). The chondrite-normalized, rare-earth-element concentrations form a “V-pattern” that is characteristic of other lunar granitic material. By modeling 12032,366-19 as a derivative from a KREEP-like parent melt, the composition and mineral assemblage can be obtained by extended fractional crystallization combined with separation of the low-density minerals plus trapped melt components prior to final solidification. However, this model cannot quantitatively account for the relatively sodic composition of the plagioclase (An34-50) and requires that the starting melt has Na2O of 1.2-1.4 wt%, which is higher than most KREEP compositions. Formation of this assemblage by silicate-liquid immiscibility is neither required nor indicated by petrogenetic modeling.
Regression test selection for TizenRT

Regression testing - running tests after code modifications - is widely practiced in industry, including at Samsung. Regression Test Selection (RTS) optimizes regression testing by skipping tests that are not affected by recent code changes. Recent work has developed robust RTS tools, which mostly target managed languages, e.g., Java and C#, and thus are not applicable to large C projects, e.g., TizenRT, a lightweight RTOS-based platform. We present Selfection, an RTS tool for projects written in C; we discuss the key challenges to develop Selfection and our design decisions. Selfection uses the objdump and readelf tools to statically build a dependency graph of functions from binaries and detect modified code elements. We integrated Selfection in TizenRT and evaluated its benefits if tests are run in an emulator and on a supported hardware platform (ARTIK 053). We used the latest 150 revisions of TizenRT available on GitHub. We measured the benefits of Selfection as the reduction in the number of tests and reduction in test execution time over running all tests at each revision (i.e., RetestAll). Our results show that Selfection can reduce, on average, the number of tests to 4.95% and end-to-end execution time to 7.04% when tests are executed in the emulator, and to 5.74% and 26.82% when tests are executed on the actual hardware. Our results also show that the time taken to maintain the dependency graph and detect modified functions is negligible.
An isoperimetric inequality for Laplace eigenvalues on the sphere

We show that for any positive integer k, the k-th nonzero eigenvalue of the Laplace-Beltrami operator on the two-dimensional sphere endowed with a Riemannian metric of unit area, is maximized in the limit by a sequence of metrics converging to a union of k touching identical round spheres. This proves a conjecture posed by the second author in 2002 and yields a sharp isoperimetric inequality for all nonzero eigenvalues of the Laplacian on a sphere. Earlier, the result was known only for k=1 (J. Hersch, 1970), k=2 (N. Nadirashvili, 2002; R. Petrides, 2014) and k=3 (N. Nadirashvili and Y. Sire, 2017). In particular, we argue that for any k>=2, the supremum of the k-th nonzero eigenvalue on a sphere of unit area is not attained in the class of Riemannian metrics which are smooth outsitde a finite set of conical singularities. The proof uses certain properties of harmonic maps between spheres, the key new ingredient being a bound on the harmonic degree of a harmonic map into a sphere obtained by N. Ejiri.
Panofsky ’ s Integral Similarity Function — At Fifty

Fifty years ago, Hans A. Panofsky published a paper entitled Determination of stress from wind and temperature measurements. In his famous paper, he presented a new profile function for the mean horizontal wind speed under the condition of diabatic stratification that includes his integral similarity function. With his integral similarity function, he opened the door for Monin-Obukhov scaling in a wide range of micrometeorological and microclimatological applications. In a historic survey ranging from the sixties of the past century down to the present days, we present integral similarity functions for momentum, sensible heat, and water vapor for both unstable and stable stratification, where on the one hand free convection condition and on the other hand strongly stable stratification are addressed.
Tungsten carbide nanoparticles in simulated surface water with natural organic matter: dissolution, agglomeration, sedimentation and interaction with Daphnia magna

Even though anthropogenic nano-sized tungsten carbide nanoparticles (WC NPs) have been found in the environment, there are currently no investigations on their environmental fate. This work studies the interaction between natural organic matter (NOM) and WC NPs, as well as the potential uptake by the aquatic model organism Daphnia magna. We here show that the affinity between WC NPs and humic acid or dihydroxybenzoic acid (DHBA), which are model molecules of NOM, is very low with no observed surface adsorption. The lack of a stabilizing effect of these organic molecules, in combination with a relatively high effective density of WC NP agglomerates in humic acid, resulted in the substantial agglomeration and sedimentation of the WC NPs. A higher stability of the smaller sized WC NP agglomerates (<150 nm) means that this fraction is mobile and can be transported to other settings, suggesting that this particle fraction should be considered in further studies. The dissolution of tungsten from WC NPs was continuous and the relatively slow dissolution rate (on the order of 0.03 mg m−2 h−1) implies that particle transport will not be severely limited from a dissolution perspective. Uptake of tungsten (dissolved tungsten and WC particles) by D. magna was observed although this did not induce any acute toxic effects.
Factors Affecting the Observed Densities of Ringed Seals, Phoca hispida , in the Alaskan Beaufort Sea, 1996-99

Aerial surveys were conducted during late May and early June 1996-99 in the central Beaufort Sea of Alaska, using strip-transect methods. The purpose of these surveys was to quantify and model the effects of environmental covariates on ringed seal counts and to provide density estimates that would be useful for evaluating trends in seal abundance. Total survey effort included 40-88 transect lines per year covering 1198-2701 km². Observed densities ranged from 0.81 seals/km² in 1996 to 1.17 seals/km² in 1999. We examined the effects of habitat, weather, and time of day on observed seal densities, using univariate chi-square goodness-of-fit tests. We also used a multivariate generalized linear model to estimate the relationship between seal counts and covariates. Three habitat-related variables - water depth, location relative to the fast ice edge, and ice deformation - had substantial and consistent effects. The highest densities occurred at depths between 5 and 35 m. Densities were also highest in relatively flat ice and near the fast ice edge, declining both shoreward and seaward of that edge. Univariate analysis suggested that observed densities were generally highest at about 1200 h Alaska daylight time, but time was not a significant variable in the generalized linear models. Analyses of the effects of weather factors on seal counts were inconclusive. This was likely at least partially because temperature and wind speed were measured at survey altitude, rather than on the ice surface, and surveys were conducted only in weather considered suitable for hauling out. The final multivariate model did not account for a substantial proportion of the variation in seal counts. We think this result was largely due to date-related variation in the proportion of seals hauling out, an issue our surveys were not suited to address.
Aspects of Early Thule Culture as Seen in the Architecture of a Site on Victoria Island, Amundsen Gulf Area

The early Thule culture site Co-op, situated at the east end of Amundsen Gulf, along the route to the eastern Arctic, offers excellent conditions for documenting the Thule expansion from Alaska, across the area of western Canadian Thule, and as far as the High Arctic. Whereas the markers most often retained to define cultures and their respective areas of expansion are movable artifacts, this paper focuses exclusively on unmovable architectural features. Detailed analyses of data obtained at the Co-op site yielded significant information about the techniques of thermoregulation of the semisubterranean dwellings. Comparisons with other Thule dwellings revealed greater stability in the architectural concept during the early phases of the Thule expansion than one would expect, given the technical constraints imposed by local raw materials and their fluctuating availability. Dwellings may therefore constitute one of the most useful identifying cultural elements.
Identifying indicator traits for breech strike in Merino sheep in a Mediterranean environment

Data from 2833 unmulesed Merino lambs from 49 sires and 1535 dams that were born from 2005 to 2009, were used to identify indicator traits for breech strike in a Mediterranean environment. Sheep were managed in a normal production environment where no preventative treatments were applied to protect them from being struck by flies, but were immediately treated when found to be fly struck. Seventy-seven skin, body conformation, wool, disease and production traits that may contribute to breech strike and that could qualify as potential indicator traits were recorded on progeny at birth, weaning, post-weaning, yearling, spring and at pre- and post-hogget age at ~18 months of age. In all, 31% of ewes and 22% of rams were fly struck in the breech area between birth and hogget shearing. The heritability of and the phenotypic and genetic correlations between the potential indicator traits and breech strike were estimated. The results showed that breech strike is a heritable trait (h2 = 0.51 ± 0.10), and that the most important indicator traits for breech strike were dags, scored at any time, especially at hogget age (rg = 0.81 ± 0.15), spring (rg = 0.77 ± 0.13) or at weaning (rg = 0.64 ± 0.00), urine stain scored at weaning (rg = 0.54 ± 0.13) and marking (rg = 0.51 ± 0.15), neck wrinkle at hogget age (rg = 0.46 ± 0.13) and breech cover (rg = 0.32 ± 0.15) scored at post-weaning shearing. These traits could be used to select indirectly for breech strike resistance in a Mediterranean environment.
A Psychological Comparison Between Ordinary Children and Those Who Claim Previous-Life Memories

It has been proposed that some normal-psychological factors may explain why some children speak of having had a previous life. Some of these and other psychological factors, which may further our understanding of children claiming prcvious-life memories, =ere ihe siibjeci of this siudy. Psychological tests were administered to 30 children in Sri Lanka, aged 7 to 13, who at an earlier age had claimed to remember a previous life, and a con- trol group of equal size. Children claiming previous-life memories show a higher level of cognitive functioning; perform much better in school, have a larger vocabulary, obtain higher scores on the Raven Progressive Matrices (brief test of intelligence), have better memory, and are not more suggestible than their peers. As a group they are gifted children. Parents found them to argue a lot, prefer being alone, be more nervous and stubborn than their peers, more perfectionistic, and more concerned about cleanliness. Teachers found them excellent to be pupils. As research continues the alleged memories of these children are found to be only one part of a pattern of characteristics that so far seem to defy a normal explanation.
Impact of Glutamine in Drinking Water on Performance and Intestinal Morphology of Broiler Chickens under High Stocking Density

This work sought to look into the impacts of glutamine in drinking water on performance, intestinal morphology and corticosterone level of chickens under different stocking densities. A total 300 male chicks randomly were divided to battery cages as 10 birds/(normal stocking density) and 15 birds/(high stocking density). The chicks received feed as (i) control diet and (ii) control diet + 5g glutamine/ liter in drinking water under normal and high stocking density for the whole experiment. On d 42, 3 chicks from each cage were randomly selected and slaughtered to collect blood and duodenal samples. The results showed significant improvement in growth performance and longer villi when chicken were supplemented with glutamine via drinking water. High stocking density impaired performance of chicks in the control diet, but not in chicken supplemented with glutamine under high stocking density condition. Moreover, high stocking density increased the level of corticosterone in the both groups. More interestingly, the rate of mortality significantly decreased in chickens fed with glutamine supplemented diet (2% when supplemented with glutamine and 5.33% without supplementation). In conclusion, glutamine supplementation via drinking water resulted in better growth performance of birds subjected to high stocking density.
The Superfluous Load Queue

In an out-of-order core, the load queue (LQ), the store queue (SQ), and the store buffer (SB) are responsible for ensuring: i) correct forwarding of stores to loads and ii) correct ordering among loads (with respect to external stores). The first requirement safeguards the sequential semantics of program execution and applies to both serial and parallel code; the second requirement safeguards the semantics of coherence and consistency (e.g., TSO). In particular, loads search the SQ/SB for the latest value that may have been produced by a store, and stores and invalidations search the LQ to find speculative loads in case they violate uniprocessor or multiprocessor ordering. To meet timing constraints the LQ and SQ/SB system is composed of CAM structures that are frequently searched. This results in high complexity, cost, and significant difficulty to scale, but is the current state of the art. Prior research demonstrated the feasibility of a non-associative LQ by replaying loads at commit. There is a steep cost however: a significant increase in L1 accesses and contention for L1 ports. This is because prior work assumes Sequential Consistency and completely ignores the existence of a SB in the system. In contrast, we intentionally delay stores in the SB to achieve a total management of stores and loads in a core, while still supporting TSO. Our main result is that we eliminate the LQ without burdening the L1 with extra accesses. Store forwarding is achieved by delaying our own stores until speculatively issued loads are validated on commit, entirely in-core; TSO load→load ordering is preserved by delaying remote external stores in their SB until our own speculative reordered loads commit. While the latter is inspired by recent work on non-speculative load reordering, our contribution here is to show that this can be accomplished without having a load queue. Eliminating the LQ results in both energy savings and performance improvement from the elimination of LQ-induced stalls.
Multi-View Silhouette and Depth Decomposition for High Resolution 3D Object Representation

We consider the problem of scaling deep generative shape models to high-resolution. Drawing motivation from the canonical view representation of objects, we introduce a novel method for the fast up-sampling of 3D objects in voxel space through networks that perform super-resolution on the six orthographic depth projections. This allows us to generate high-resolution objects with more efficient scaling than methods which work directly in 3D. We decompose the problem of 2D depth super-resolution into silhouette and depth prediction to capture both structure and fine detail. This allows our method to generate sharp edges more easily than an individual network. We evaluate our work on multiple experiments concerning high-resolution 3D objects, and show our system is capable of accurately predicting novel objects at resolutions as large as 512$\mathbf{\times}$512$\mathbf{\times}$512 -- the highest resolution reported for this task. We achieve state-of-the-art performance on 3D object reconstruction from RGB images on the ShapeNet dataset, and further demonstrate the first effective 3D super-resolution method.
Impact of Diet Supplemented by Coconut Milk on Corticosterone and Acute Phase Protein Level under High Stocking Density

The purpose of this study was to investigate effects of coconut milk supplementation on corticosterone and acute phase protein level under high stocking density. A total 300 Cobb 500 male chicks were placed in cages and stocked as 10 birds/cage (normal stocking density) and 15 birds/cage (high stocking density). The treatments were as (i) control diet and stocked at 10 and 15 birds/cage (ii) control diet + 3% coconut milk from 1-42 day and stocked at 10 and 15 birds/cage (iii) control diet + 5% coconut milk from 1-42 day and stocked at 10 and 15 birds/cage. On day 42, 20 birds per treatment were slaughtered to collect blood samples. The results showed higher level of corticosterone and acute phase protein level in control diet compare to other supplemented diets with coconut milk. In conclusion, coconut milk decreased the level of corticosterone and acute phase protein when chicks were subjected to high stocking density.
Minimizing Burnout through Reflection: The Rocky Road ahead of EFL Teachers

Teacher reflection has been recently promoted based on the claim that it positively affects various aspects of teaching and provides solutions to some of the challenges teachers encounter in their career. However, these arguments are mainly theory-driven with little empirical evidence indicating the constructive role of teachers' involvement in reflection. Inspired by this scarcity of research, the first objective of this mixed-methods study was to examine how English as a foreign language (EFL) teachers' engagement in reflective practice can be associated with their burnout. To this end, 223 Iranian EFL teachers completed reflection and burnout inventories. The results indicated that reflection is negatively correlated with burnout implying that involvement in reflective practice is associated with less burnout. Having found this, we conducted some interviews to explore the factors which impede teachers' reflection. Analysis of interview data revealed that impediments to reflection can be divided into the four categories of teacher related, job related, curriculum related and student related issues. Implications of this study for teacher education research and practice are discussed.
