Does treating the permanent workforce well matter to temporary employees?
The article focuses on a study by Bard Kuvaas and Anders Dysvik testing their hypothesis that the development opportunities for permanent employees affect how temporary employees view their positions, their job behavior, and their social exchange relationship with the organization. The authors note that Kuvaas and Dysvik employ a social information processing perspective in which the social climate of an organization is a factor. The authors report that this hypothesis was validated in Kuvaas and Dysvik's survey of 375 temporary employees
Don't Pay Attention to the Noise: Learning Self-supervised Representations of Light Curves with a Denoising Time Series Transformer
Astrophysical light curves are particularly challenging data objects due to the intensity and variety of noise contaminating them. Yet, despite
the astronomical volumes of light curves available, the majority of algorithms used to process them are still operating on a per-sample
basis. To remedy this, we propose a simple
Transformer model –called Denoising Time Series Transformer (DTST)– and show that it excels
at removing the noise and outliers in datasets of
time series when trained with a masked objective, even when no clean targets are available.
Moreover, the use of self-attention enables rich
and illustrative queries into the learned representations. We present experiments on real stellar light
curves from the Transiting Exoplanet Space Satellite (TESS), showing advantages of our approach
compared to traditional denoising techniques1
Public Access Defibrillation
The single most important cause of death in the adult population of the industrialized word is sudden cardiac death (SCD) due to coronary artery disease (CAD). In a population based study the overall yearly incidence of SCD was 1 per 1000 persons aged20 to 75 years of age. Overall 21% of deaths in men and 15% in women were sudden and unexpected. The vast majority of out of hospital deaths occur at home and about 15% in a public place or on the street. Forty percent of SCDs were unwitnessed. Themajority of patients have ventricular tachycardia or fibrillation as the first recorded rhythm after patients collapse
Automatic External Defibrillator: Training and Practical Issues
Sudden cardiac death is the single most important cause of death in the industrialized countries. In general, traditional Emergency Medical Systems (EMS) have been only minimally effective in treating out-of-hospital cardiac arrest, and this occurred mainly due to unacceptably long times from patient collapse to defibrillation. The use of automated external defibrillators (AED) by non-medical personnel, offers an appealing solution of this problem. It can be used safely and effectively by a variety of crews of social security services and public responders who have the potential of approaching the victims of cardiac arrest earlier than the ambulance crews. Therefore time to defibrillation may be shortened. For public access defibrillation (PAD) programs to be effective, they should be integrated into an emergency medical system strategy for treating patients with cardiac arrest. All aspects of implementation should be planned very carefully. Recommended elements for PAD programs include a planned and practiced approach, training of anticipated rescuers in cardiopulmonary resuscitation (CPR) / AED, link with the local EMS, continuous program review and quality improvement. Emphasis should be placed not only on making potential rescuers familiar with CPR/AED practice, but also in giving detailed directives for successful resuscitation of cardiac arrest victims in the specific location where the PAD program has been implemented

Prevention of fish photobacteriosis. Comparison of the efficacy of intraperitoneally administered commercial and experimental vaccines
Two commercial multivalent vaccines against vibriosis, caused by Vibrio anguillarum serotype(s) and photobacteriosis, caused by Photobacterium damsela subsp. piscicida, one with oil adjuvant (AJ) and the other,being an aqueous solution (AV), and an experimental monovalent (Ph. damselae subsp. piscicida) vaccine inactivated with formalin or heat, namely EVF and EVH, were tested in laboratory trials on sea bass (Dicentrarchus labrax) in respect to their efficacy against experimentally induced photobacteriosis. The first trial aiming at high bacterial pressure was carried out 34 days post-vaccination and resulted in 90% mortalities in the control. The relative per cent survival (RPS) of vaccinated fish was calculated at 24, 3.7, 0 and 0 for the AJ, AV, EVF and EVH formulations, respectively. The second trial aiming at medium bacterial pressure was carried out 49 days post-vaccination and resulted in 45% mortalities in the control. The relative per cent survival (RPS) of vaccinated fish was calculated at 100, 92.7, 77.8 and 66.7 for the AJ, EVF, EVH and AV, formulations, respectively. Apparently, under both these high and medium bacterial pressure conditions, the commercial vaccine AJ performed better than the commercial vaccine AV, while under medium pressure there was no statistical difference between the performance of EVF and AJ. The measurement of specific antibody titers in sera collected from all fish groups 49 days post-vaccination, showed high levels in the fish vaccinated with the AJ vaccine, almost three times lower levels for the AV and EVF vaccines and even lower levels for the EVH vaccine. Results are discussed in respect to the choices mariculture companies have in selecting a commercial vaccine against photobacteriosis and possible alternatives, which, if commercially developed, may reduce vaccine cost
Predicting Landslide Risk Combining Space Measurements and Geotechnical Modeling: Application at Kerasia Slide
The work developed and applied a methodology combining (a) space measurement of past displacement and (b) geotechnical modelling of displacement to predict and mitigate the risk of ground displacement cased by progressive slope instability. The area of study is in Kerasea village in Plastiras Lake Municipality. The problem under treatment is a creeping landslide in an inhabited area. Mitigation measures were analyzed
Klotho and the treatment of human malignancies
Klotho was first discovered as an anti-ageing protein linked to a number of age-related disease processes, including cardiovascular, renal, musculoskeletal, and neurodegenerative conditions. Emerging research has also demonstrated a potential therapeutic role for Klotho in cancer biology, which is perhaps unsurprising given that cancer and ageing share similar molecular hallmarks. In addition to functioning as a tumour suppressor in numerous solid tumours and haematological malignancies, Klotho represents a candidate therapeutic target for patients with these diseases, the majority of whom have limited treatment options. Here, we examine contemporary evidence evaluating the anti-neoplastic effects of Klotho and describe the modulation of downstream oncogenic signalling pathways, including Wnt/β-catenin, FGF, IGF1, PIK3K/AKT, TGFβ, and the Unfolded Protein Response. We also discuss possible approaches to developing therapeutic Klotho and consider technological advances that may facilitate the delivery of Klotho through gene therapy

Occupational health and safety disclosures in sustainability reports: An overview of trends among corporate leaders
The purpose of this study is to assess the comprehensiveness of voluntary occupational health and safety (OHS) disclosures of large business entities. We devise a composite disclosure index, relying on well‐established performance indicators, and focus on the information found in the sustainability reports of corporations pertaining to the oil and gas, chemical, airline, and construction industries, in an attempt to shed light on the current status and emerging trends in OHS reporting from a diverse group of business entities. The findings indicate that companies tend to place emphasis on their overall management approach to OHS, but fall short in reporting quantitative and qualitative information beyond the ‘conventional’ metrics of occupational injury rates. OHS issues within the supply chain and relevant monitoring systems/mechanisms in place are topics that are underreported, while OHS training programmes are an aspect that is inadequately analyzed in quantitative terms, being the least reported indicator in the sample reports. In contrast, companies from all four industries seek assurance for the OHS information that they report and place emphasis on the externally developed management standards/initiatives that they subscribe to, support, or have adopted
