Young Seasonal Employees : How Work Conditions and Burnout Contribute to Turnover Intentions

To date there has been little research conducted on young seasonal workers, leaving a dearth in the literature regarding such things as how they react to their work environment and the outcomes of those reactions. This study focuses on burnout in young seasonal workers in the amusement park industry, using the job demands-resource model to make predictions. Surveys from 155 young seasonal workers at six amusement parks on the eastern coast of the US responded to surveys at two points in time measuring job demands, job resources, burnout, and intention to turnover. Hypotheses were tested using moderated regression to investigate how job demands moderated by job resources influences burnout and how burnout influences turnover intention. While burnout was strongly related to turnover intention, the results challenged the notion that job resources moderates the relationship between job demands and burnout. A reinterpretation of the results suggests that job resources directly influence burnout and this is moderated job demands such that as job resources were low and job demand increased, burnout also increased. Results suggest that studying this population is important as young adults may react differently to their environment than mature adults working in fulltime jobs. In addition, as job lack of job resources was related to burnout, it is suggested interventions targeting managers could be used to mitigate burnout in this population

If Only They Tried; The Complicated Crusade for Salvation in the Post-Katrina Education Reform Movement

Education reform is shifting the landscape of New Orleans public schools, where alternative certification programs are thriving and changing the demographics of core teachers. This study follows a Teach for America (TFA) Corps Member from 2007 (just after the historic flooding from Hurricane Katrina) who brought a promise of innovation through idealism and green wisdom. The teacher’s preparation and motivations are shown to be problematic. Examining the assumptions and privileges that underlie the import of inexperienced talent to urban education systems, this study considers the ways that community voices have been lost or undervalued in New Orleans schools. The thesis tracks five unique student experiences in two schools over nine years, with accounts of the daily life of students and educators, some of whom are effective and make marked contributions to the community. The study concludes that care should be taken as reform continues to make schools better for kids

Hydroclimate variability from western Iberia (Portugal) during the Holocene: insights from a composite stalagmite isotope record. Holocene, (2020): 095968362090864, doi:10.1177/0959683620908648.Iberia is predicted under future warming scenarios to be increasingly impacted by drought. While it is known that this region has experienced multiple intervals of enhanced aridity over the Holocene, additional hydroclimate-sensitive records from Iberia are necessary to place current and future drying into a broader perspective. Toward that end, we present a multi-proxy composite record from six well-dated and overlapping speleothems from Buraca Gloriosa (BG) cave, located in western Portugal. The coherence between the six stalagmites in this composite stalagmite record illustrates that climate (not in-cave processes) impacts speleothem isotopic values. This record provides the first high-resolution, precisely dated, terrestrial record of Holocene hydroclimate from west-central Iberia. The BG record reveals that aridity in western Portugal increased secularly from 9.0 ka BP to present, as evidenced by rising values of both carbon (δ13C) and oxygen (δ18O) stable isotope values. This trend tracks the decrease in Northern Hemisphere summer insolation and parallels Iberian margin sea surface temperatures (SST). The increased aridity over the Holocene is consistent with changes in Hadley Circulation and a southward migration of the Intertropical Convergence Zone (ITCZ). Centennial-scale shifts in hydroclimate are coincident with changes in total solar irradiance (TSI) after 4 ka BP. Several major drying events are evident, the most prominent of which was centered around 4.2 ka BP, a feature also noted in other Iberian climate records and coinciding with well-documented regional cultural shifts. Substantially, wetter conditions occurred from 0.8 ka BP to 0.15 ka BP, including much of the ‘Little Ice Age’. This was followed by increasing aridity toward present day. This composite stalagmite proxy record complements oceanic records from coastal Iberia, lacustrine records from inland Iberia, and speleothem records from both northern and southern Spain and depicts the spatial and temporal variability in hydroclimate in Iberia.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported, in part, by the US National Science Foundation (Grants: #1804528 to ADW; #1804635 to RD; #1804132 to CCU; #1806025 to YA and VP; #1805163 to DPG; BCS-0455145, BCS-0612923, and BCS-1118155 to JAH)

NEGLIGENCE-LIABILITY OF PUBLIC AMUSEMENT OPERATORS FOR DANGEROUS PREMISES

While a patron at a dog race track, plaintiff suffered injuries when she slipped on an empty beverage bottle left in the aisle of the grandstand. In an action against the proprietor, a motion for directed verdict in favor of defendant was granted on the theory that plaintiff had failed to show defendant\u27s actual or constructive knowledge of the presence of the bottle; the trial court further stated that if constructive knowledge were relied on, the plaintiff must prove that the bottle had been in the grandstand long enough for the owners, in the exercise of reasonable care, to have discovered and removed it. Held, reversed; while this may be the correct rule with respect to ordinary places of business, it is not applicable in the case of a public amusement park, where many patrons fill the aisles and are permitted to purchase and drink bottled beverages and to set the empty bottles anywhere. The question of whether defendant exercised ordinary care should have been submitted to the jury. Wells v. Palm Beach Kennel Club, (Fla.1948) 35 S. (2d) 720

CLARK: fast and accurate classification of metagenomic and genomic sequences using discriminative k-mers.

BackgroundThe problem of supervised DNA sequence classification arises in several fields of computational molecular biology. Although this problem has been extensively studied, it is still computationally challenging due to size of the datasets that modern sequencing technologies can produce.ResultsWe introduce CLARK a novel approach to classify metagenomic reads at the species or genus level with high accuracy and high speed. Extensive experimental results on various metagenomic samples show that the classification accuracy of CLARK is better or comparable to the best state-of-the-art tools and it is significantly faster than any of its competitors. In its fastest single-threaded mode CLARK classifies, with high accuracy, about 32 million metagenomic short reads per minute. CLARK can also classify BAC clones or transcripts to chromosome arms and centromeric regions.ConclusionsCLARK is a versatile, fast and accurate sequence classification method, especially useful for metagenomics and genomics applications.

A Late Holocene Reconstruction of Ocean Climate Variability in the Gulf of Maine, USA, Based on Calibrated Isotope Records and Growth Histories from the Long-lived Ocean Quahog (Arctica islandica L.)

Understanding regional patterns of interannual to decadal-scale climate variability over the past 1000 years is critical for evaluating recently observed trends in atmosphere/ocean conditions, particularly in highly-productive ecosystems such as the Gulf of Maine (GOM) that are sensitive to minor changes in climate and/or changes in slope water input. To develop quantitative relationships between bivalve shell chemistry (d18Oc) and growing conditions, aquaculture-based experiments were developed using Mytilus edulis collected in the GOM and Greenland. These experiments yielded a highly accurate and precise paleothermometer [e.g., T °C = 16.28 (± 0.10) - 4.57 (± 0.15) {d18Oc VPBD – d18Ow VSMOW} + 0.06 (± 0.06) {d18Oc VPBD – d 18Ow VSMOW}2; r2 = 0.99; N= 323; p \u3c 0.0001] for M. edulis, and the techniques were applied to the long-lived bivalve species Arctica islandica. To examine ocean variability in the Western GOM during the last millennium, a 142-year-old living A. islandica and three fossil A. islandica shells (corrected 14CAMS = 1030 ± 78 AD; 1320 ± 45 AD; 1357 ± 40 AD) were collected for d18O and growth increment analysis. The standardized annual growth index (SGI) of the modern shell is significantly correlated with continuous GOM plankton recorder data (1961 – 2003; Calanus finmarchicus; r2 = 0.55; p \u3c 0.0001), and SGIs during the late Holocene contain significant periods of 2-6 years, suggesting that slope water variability coupled with North Atlantic Oscillation (NAO) dynamics is primarily responsible for productivity variability. Mean shell-derived isotopic changes were + 0.47 ‰ from 1000 AD to present, and likely reflect a 2 °C cooling caused by an increase in Labrador Current (LC) transport of ~ 0.7 Sv (1 Sv = 106 m3 s-1) and a corresponding decrease in Gulf Stream influence on GOM water temperatures during the past millennium. This hypothesis is consistent with modern observational relationships among the LC, GOM water temperatures, NAO, and Atlantic Multi-Decadal Oscillation (AMO). These results corroborate recent evidence of a large-scale cooling of slope waters and/or dynamical oceanographic changes outside the GOM during the Holocene, and suggest that a direct link exists between the GOM and Northwestern Atlantic
