Features of Legal Regulation of Employment Contracts with Seasonal and Temporary Employees

The article is focused on studying peculiarities of employment contracts with seasonal and temporary employees in Ukraine. The employment contract as the basis of the origin of labor relations with seasonal and temporary employees has been researched. The norms of the decrees of the Presidium of the Supreme Rada of the USSR “On working conditions of temporary employees and officials” dated from September 24, 1974 No. 311-09 and “On working conditions of employees and officials engaged in seasonal work” dated from September 24, 1974 No. 310-09 have been analyzed .&#x0D; It has been noted that peculiarities of legal regulation of employment contracts with temporary and seasonal employees relate primarily to their conclusion and termination, as well as content. It has been proved that some provisions of regulatory acts that regulate the employment of temporary and seasonal employees are outdated; others require some revision.&#x0D; It has been offered to develop modern regulatory acts on the application of temporary and seasonal work. These acts must first of all establish the concept: “seasonal employees – individuals hired under an employment contract for work that as a result of natural and climatic conditions performed not through a year, but during a certain period (season), not exceeding six months”; “temporary employees – individuals hired under an employment contract for a period up to two months, and for the replacement of temporarily absent employees, who retain their place of work (position) – up to four months”. It has been substantiated that the List of Seasonal Works and Seasonal Industries needs to be updated, based on the realities of the present day.

A Carcinogenicity Bioassay of Isobutyl 2-Cyanoacrylate (IBC) in Fischer-344 Rats -- One-Year Interim Sacrifice Report. Volume 2. Part 1

Abstract : This report covers the results from the first year of a two-year carcinogenicity bioassay of the tissue adhesive, isobutyl 2-cyanoacrylate (IBC). Four hundred seven 6-week old Fischer-344 rats were randomized into three groups (control, 10 ul IBC, and 100 ul IBC), each group containing both male and female animals. The IBC was administered by surgical implantation of liquid monomer directly onto the ventral capsule of the liver. The monomer was allowed to polymerize before two-layer closure of the abdominal incision. Control animals received 100 ul of isotonic saline also by surgical implantation. Results of this study indicate that IBC has no effect on survival, weight gain, or the clinical condition of rats during the first year following its implantation. The only gross or histopathological finding observed in the first year attributed to the IBC treatment was the presence of adhesions on and a granulomatous reaction of the liver and those adjacent organs that came in contact with the IBC. No tumors were observed during the first year that could be attributed to IBC treatment. Keywords: Adhesives, Neoplasmas, Surgery.

Temperature and pH-Responsive Release Behavior of PVA/PAAc/PNIPAAm/MWCNTs Nanocomposite Hydrogels

A drug delivery system (DDS) was prepared with a temperature and pH-responsive hydrogel. Poly(vinyl alcohol) (PVA)/poly(acrylic acid) (PAAc)/poly(N-isopropylacrylamide) (PNIPAAm)/multi-walled carbon nanotube (MWCNT) nanocomposites were prepared by radical polymerization for the temperature and pH-responsive hydrogels. MWCNTs were employed to improve both the thermal conductivity and mechanical properties of the PVA/PAAc/PNIPAAm/MWCNT nanocomposite hydrogels. Various amounts of MWCNTs (0, 0.5, 1 and 3 wt%) were added to the nanocomposite hydrogels. PVA/PAAc/PNIPAAm/MWCNT nanocomposite hydrogels were characterized with a scanning electron microscope. The mechanical properties were measured with a universal testing machine. Swelling and releasing properties of nanocomposite hydrogels were investigated at various temperatures and pHs. Temperature and pH-responsive release behavior was found to be dependent on the content of MWCNTs in nanocomposite hydrogels.

Metabolic Tumor Profiling with pH, Oxygen, and Glucose Chemosensors on a Quantum Dot Scaffold

Acidity, hypoxia, and glucose levels characterize the tumor microenvironment rendering pH, pO2, and pGlucose, respectively, important indicators of tumor health. To this end, understanding how these parameters change can be a powerful tool for the development of novel and effective therapeutics. We have designed optical chemosensors that feature a quantum dot and an analyte-responsive dye. These noninvasive chemosensors permit pH, oxygen, and glucose to be monitored dynamically within the tumor microenvironment by using multiphoton imaging.

COLOR SCREENING EFFECT IN THE QUARK POTENTIAL MODEL

By using the color confinement potential which includes the color screening effect, we studied the baryon spectra and the nucleon-nucleon interaction. The results show that the color screening effect not only improves the baryon spectrum calculation, but also can solve the long-tail problem of the color Van der Waals force. A part of the medium attraction of the nuclear force can be obtained from the color Van der Waals force.

[Research on the extracorporeal cytocompatibility of a composite of HA, carbon fiber and polyetheretherket-one].

The present research was to study the biocompatibility of a composite of hydroxyapatite (HA), carbon fiber (CF) and polyetheretherket-one (PEEK) by co-culturing with the osteoblasts in vitro. Cell relative growth (RGR) was used as a quantitative assessment for cytotoxicity of the biomaterials by CCK-8. The proliferation index of the co-cultured cells and ALP activity was measured to study the effect of PEEK-HA-CF composites. Morphological properties of the osteoblast cells in vitro were observed by scanning electro-microscopy (SEM). The PEEK-HA-CF materials have no cytotoxicity to osteoblasts. The proliferation index of PEEK-HA-CF was higher than that of Ti alloy group, but these was no significant difference compared to that of control group. The ALP activity was the highest on PEEK-HA-CF composites surface after 7 days. The osteoblast cells co-cultured with the PEEK-HA-CF composite were adhered well to the biomaterial as observed under the SEM. The results suggested that the PEEK-HA-CF composites had good biocompatibility in vitro and might be a novel orthopedic implanted material.

Fast Deterministic Sampling for Mean and Covariance Estimation in Stochastic Load Flow

This paper proposes a new method for stochastic load flow (SLF) by using deterministic sampling based on sigma-point selection. In stead of conducting time-consuming Monte Carlo simulation, the proposed method can efficiently estimate the mean and covariance of state variables and branch power flow by conducting only 2k+ chosen deterministic power flow for a power system with k normally distributed uncertain parameters. The benefits of the proposed method are: 1) it has accuracy at least to the second order of truncated Taylor series; 2) it needs no derivatives; 3) it is not limited to the size of uncertain parameters. The effectiveness of the proposed method is demonstrated in an example of IEEE 14-bus power system.

Secrets and Lies: The Power of Thetis in Roman Culture

Slatkin has taught us that an awareness of the hidden tradition of the cosmological power of Thetis is crucial to understanding the Iliad; it is no less important for understanding the subsequent literary tradition. Apollonius expanded upon Homer's hints at the unhappiness of Thetis to depict the Nereid as disgusted with the marriage that has thwarted her destiny, even as Hera continues to claim blithely that her wedding was a happy occasion. Catullus 64 is built upon this contrast between the official, mendacious version of the wedding as a happy occasion and the secret, darker story in which the bride's grand destiny was sacrificed to ensure the hegemony of Jupiter. Virgil takes a broader view of cosmic history. In Eclogue 4, he embeds Catullus' narrative of irreversible decay into a cyclical framework while in the Aeneid the trajectory of Venus pointedly inverts the decline of Thetis' power. Ovid and Statius bring out further elements of Thetis' stymied power. In each case, readers had to bring to bear their extra-textual knowledge of the real reason for Thetis' marriage and of its consequences; and even Roman wall painters could presuppose that viewers knew her secret history.

A Study of the Correlation between Brain-type Natriuretic Peptide (BNP) Levels &amp; Left Ventricular Ejection Fraction (LVEF) in Heart Failure

Background: A significant proportion of patients diagnosed as heart failure have preserved ejection fraction. However, the differentiation between heart failure with reduced &amp; preserved ejection fraction is difficult. The objectives of the study include: To assess the BNP levels in both patients with Heart failure with preserved LV ejection fraction and those with reduced LV ejection fraction. To study the correlation between the BNP levels and LVEF in both the groups and to ascertain whether BNP can be an useful tool in diagnosis of Heart failure with preserved LV ejection fraction]. Methods: The medical records of young patients (20–40 years) admitted during the two years 2014 &amp; 2015 and diagnosed with Heart Failure were scrutinized in an attempt to determine the proportion of patients with preserved vs reduced ejection fraction and to assess the relationship between their Brain-type Natriuretic Peptide (BNP) levels &amp; Left Ventricular Ejection Fraction (LVEF) in both the groups.&nbsp; Results: After Statistical analysis, it was found that around 36% of heart failure patients had preserved ejection fraction. There was a negative correlation between BNP levels &amp; LVEF in both heart failure with reduced ejection fraction (HFrEF) as well as that with preserved ejection fraction (HFpEF). Majority of patients in HFpEF group were females. Mean BNP level in HFpEF group was significantly lower than that in the HFrEF group.&nbsp; Conclusion: Around one third of patients had Heart Failure with preserved systolic function, of which majority are females. There is a strong negative correlation between BNP levels and LVEF% in both the groups. Thus BNP levels can be used in the differentiation of HFpEF and HFrEF.

Hydrogen production from biomass by integrating thermochemical and biological processes

The purpose of this research was to contribute to the development of H\\(_2\\) production technologies from biomass. The study integrated thermochemical processes to achieve biomass hydrolysis with biological methods to then obtain H2 by the fermentation of these hydrolysates using E. coli.&#13;\nDifferent strains of E. coli were tested under controlled conditions in 3 L scale fermentations with the aim to find the most useful strain for the fermentation process in terms of H\\(_2\\) produced and the subsequent hydrogen production potential of the organic acid co-products in a downstream photofermentation. Among the strains tested FTD89, FTD67 and RL009 gave the best results, however ethanol was successfully abolished by strain RL009 making this strain more suitable for long term fermentations.&#13;\nModel polysaccharide compounds such as starch and cellulose, and representative food and lignocellulosic wastes were hydrolysed in hot compressed water in the presence of CO\\(_2\\) under pressure and various temperatures to produce hydrolysates with high sugar content suitable for fermentation for H\\(_2\\) production. Optimum hydrolysis conditions for maximum sugar yields for each compound were determined. Fermentation of the obtained hydrolysates yielded acceptable amounts of H\\(_2\\) after their ‘detoxification’ with activated carbon (AC), comparable to H\\(_2\\) yielded by the glucose controls in all cases. The maximum yield of glucose after HCW treatment was obtained from starch at 200 °C yielding 548 g C.kg C initial starch\\(^{-1}\\); maximum glucose yield from cellulose was 225 g C.Kg C initial cellulose\\(^{-1}\\) obtained from cellulose hydrolysis at 250 °C, and the glucose yield from food waste was 45.5 g.g food waste\\(^{-1}\\). The main degradation product (DP) from these hydrolysates was 5 Hydroxymethylfurfural (5-HMF), whereas the main DP obtained from the lignocellulosic wastes was Furfural. Both were successfully removed by AC treatment.&#13;\nThe best hydrolysate obtained from wastes was evaluated for H\\(_2\\) production at 3 L scale. Despite obtaining low H\\(_2\\) yields improvements would be possible and are discussed. Fermentations for H\\(_2\\) production at pilot plant scale were also trialled, indicating key areas for future development for successful scale up.

Contrasting and altitude‐specific temporal trends in functional, phylogenetic, and species diversity in Austrian butterfly communities

Climate change and anthropogenic alteration of landscapes negatively impact the abundance and species diversity of plant and animal communities worldwide. Much less is known about the effects on phylogenetic diversity and community functioning. Here we use long‐term butterfly data (1980–2022) from the Austrian Alps along an elevation gradient. We assessed how communities adjust structures and functionality to increasing temperatures, and how these changes are linked to trait expression and community functioning. Species diversity decreased at low and intermediate altitudes, and increased at high ones. Functional diversity was lower than expected by a random model at intermediate and high altitudes and increased with time at high, but not at intermediate and low altitudes. Phylogenetic diversity did not show significant temporal trends at low altitude, but increased with time at intermediate and high altitudes. Multifunctionality significantly decreased at intermediate and high altitudes and was not significantly correlated with functional diversity, but was negatively correlated with phylogenetic diversity. We argue that the ongoing homogenisation of Alpine butterfly communities strongly affects species, functional and phylogenetic diversity. The assessment of species richness and diversity alone, as provided by common species surveys, might give a false impression about the state and functional diversity of Alpine insect communities in the course of climate change. The directions of faunal changes heavily depend on altitude and therefore on specific climatic conditions. Higher altitudes face decreasing butterfly multifunctionality despite of increasing species richness due to climate induced altitudinal up‐hill shifts of many species. We conclude that studies on community time series should include phylogenetic and functional diversity besides of being focused on richness and endangerment. Red lists might be extended by categories on functional importance and phylogenetic distinctness.

Essays on Crime and Public Policy

This dissertation consists of three chapters. The first chapter analyzes the impact of sanctuary policies on criminal behavior. Sanctuary policies may attract criminals and lower the opportunity cost of crime, while these policies produce a spiral of trust that supports police and raises informal social control over crime. I estimate the dynamic effects of sanctuary policies on crime rates at city level. This chapter finds (1) no evidence that sanctuary policies cause an increase in any crime, (2) some evidence that they may lead to a decrease in property crime, and the effect is strengthened over time after the adoption, (3) the increased trust between residents and police is likely the reason for the negative effect. The second chapter analyzes the relationship between visitation experience and recidivism outcomes. Visitation in prison is associated with a low recidivism rate after release. However, in the literature, it is not clear whether visitation has a causal effect. This chapter tries to estimate the effect of visitation experience on the recidivism outcome of state prisoners in Missouri, using an instrumental variable approach. The instrumental variable used for identification is the distance from a prison to an address before incarceration, since prisoners are less likely to be visited when they are assigned to prisons far from home. The results support that visitation has a causal effect on recidivism. The visitation effect within one year is robust to different samples, control variables, and specifications, but becomes ambiguous after one year. Hence, the key difference from other studies is the timing of the measured recidivism outcome. Moreover, visitation improves employment outcomes; therefore, employment is an important channel of the visitation effect. However, no discernible effect on housing stability is found. The third chapter analyzes the relationship between health conditions and criminal behavior. Health has a significant impact on labor market outcomes, and thus on criminal decisions. We document that better health is associated with a lower probability of committing a crime. To study the economic mechanism behind this finding, we build an equilibrium search model of health, crime, and the labor market. We perform policy experiments in the model and study their impacts on crime and the labor market. The calibrated model shows that by introducing Medicare-for-all, the economy's crime rate would decrease by one percentage point while the aggregate output would increase by more than 10%.
