Linear and spatial variability of eucalyptus dendrometric attributes correlated with the properties of a Typic Haplustox soil (Oxisol) in the Brazilian savannah

Effects of soil attributes using the geostatistical tool improves the interpretation of specific soil management. Thus, this study aimed to evaluate the physical, chemical, and microbiological properties of a Typical Haplustox (Oxisol), identifying those with the best linear and spatial correlation with eucalyptus (Eucalyptus spp.) vegetative growth. The experiment was conducted at the Teaching, Research, and Extension Farm (FEPE) of the Universidade Estadual Paulista (UNESP), Campus of Ilha Solteira. Thirty-five points spaced 13 meters apart were demarcated for analysis, which were distributed in 5 rows of 7 points each. From each point, 2 soil samples were collected from the 0-10 cm depth layer. The physical, chemical, and microbiological soil properties evaluated were: sand, silt, and clay contents; penetration resistance (PR), gravimetric moisture (GM), real density (RD), microbial biomass carbon (MBC), respirometry (CO2-C), metabolic quotient (qCO2), organic matter content (OM), and hydrogenionic potential (pH). The eucalyptus attributes assessed were: plant height (PH) and circumference at breast height (CBH). Each attribute was analyzed by descriptive statistics using the SAS software. Data frequency distribution was verified by the Shapiro Wilk method, and geospatial changes were analyzed by the GS+ software. The soil property that best explained the variability in eucalyptus dendrometric attributes was real density (RD). Except for RD, all properties did not show spatial dependence (i.e., pure nugget effect), which significantly represents eucalyptus vegetative performance.

CULTURAL SUSTAINABILITY OF THE HEARTH CONCEPT IN TURKISH SHELTERS

From the cave to today's residence, in addition to the need for shelter in every place, nutrition has been another important need. While the nutritional needs were met, the concept of the hearth was formed with the discovery of fire and the emergence of the act of cooking. The hearth, which continues to exist in different forms in shelters; It has also had an important place in Turkish culture over time. The cultural sustainability of the concept of the hearth, which can still exist today under different names and places, is a matter of debate. The aim of the study is to examine the spatial and structural changes of the concept of hearth and its cultural sustainability. In this context, a literature review on the use of the concept of hearth in four different periods has been made and its position in the space has been examined. In addition, online and face-to-face surveys were conducted with age groups in three different generations (X, Y and Z generations) in order to evaluate the cultural sustainability of the concept of hearth. The questionnaire form was prepared on a Likert type scale, and the data at the end of the questionnaire were analyzed using the SPSS 23.0 program. While evaluating the data, frequency, percentile distribution and arithmetic mean were used. As a result of the examinations, the change of the concept of the hearth in the Turkish shelters was tried to be revealed, and inferences were made about the cultural sustainability of the hearth.

Workplace Violence Against Police Officers and The Effect of Workplace Violence on Mental Health

Aim: The aim of the research is to reveal the prevalence of violence against police officers and to examine the effect of being subjected to violence on their mental health. Methods: The sample of the research consists of 339 police officers working in different duty areas. Questionnaire technique was used to collect data in the study. The questionnaire form consists of two parts. In the first part of the questionnaire, there are questions to determine the demographic characteristics of the participants (age, gender, marital status, education level, working year, etc.). In the second part of the questionnaire, there are questions to measure workplace violence and the Depression-Anxiety-Stress Scale. SPSS 23.0 package program was used in the analysis of the research data. Frequency distribution, descriptive statistics and t-test were used in the analysis of the data. Results: In the current study, it has been determined that 39.2% of police officers have been exposed to at least one type of workplace violence in the last 1 year. It was observed that the most common type of violence was verbal violence (28.9%). The results show that exposure to workplace violence negatively affects the stress and depression levels of police officers. Conclusion: Research results show that workplace violence is an important risk factor for police officers. Being exposed to violence also negatively affects the mental health of police officers. These results show the importance of implementing policies to prevent violence against police officers. Keywords: Police Officers, Workplace Violence, Stress, Depression And Anxiety

MEASURING VALUE AT RISK USING GARCH MODEL - EVIDENCE FROM THE CRYPTOCURRENCY MARKET

There is a growing interest in the activities of the crypto market by various stakeholders. These stakeholders generally include investors, entrepreneurs, governments, fund managers, climate activists, institutional managers, employees with surplus funds, and crypto miners. This study aims to investigate the accuracy of the GARCH models for measuring and estimating Value-at-risk (VaR) using the Cryptocurrency index for future investment and managerial decision making. Because of this, the present study uses the top 30 Cryptocurrencies index in terms of Market capitalization excluding stable coins to determine the best GARCH models. Many entrepreneurs, institutional managers, fund managers, and other stakeholders have recently included cryptocurrency in their investment portfolio because of the increase in transactions and high returns growth in the global financial market with its associated high returns and volatility. Information communication technology has paved the way for such activities in the global markets. The daily data frequency was applied because of the availability of the data. The empirical analysis has been carried out for the period from January 2017 to December 2020 for a total of 1461observation. The returns volatility is estimated using SGARCH and EGARCH models. The findings evidenced that, using both normal distribution and Student t distribution, EGARCH provides a better measure and estimate than SGARCH concerning high persistence and volatility. Against this background, the present study also examined Backtesting to estimate Value at Risk. Interestingly, the findings of the available study would provide industry players, practitioners, entrepreneurs, and investors the maximum edge on how to use or measure such variables against others to make investment decisions. Also, the findings would subsequently contribute more insight into academia on the study area.

Bilateral neurorethinovasculitis associated with COVID-19 infection in a girl 17 years old

Despite dominant lung lesions, new coronavirus infection (COVID-19) can influence almost any organ, including eyes. According to modern data, frequency of eye damage by COVID-19 reaches 32%, and spectrum of clinical manifestations is diverse. Changes are observed both in the anterior (mainly conjunctivitis) and posterior (mostly retinal vascular thrombosis, optic neuritis, neuroretinitis) segments of the eye, and the timing of their occurrence varies from the first (sometimes the only) clinical symptoms of the disease to the development at the peak or during the period of convalescence from COVID-19. In children symptomatic COVID-19 infection is diagnosed less frequently than in adults, and ophthalmic manifestations are less investigated. This article describes a case of bilateral neuroretinovasculitis in a 17-year-old girl with a mild course of COVID-19, that arose 3 weeks after the onset of the disease, which broadens the understanding of ocular manifestations of COVID-19 in children. We emphasize that an ophthalmologist should know ocular manifestations of COVID-19, which can help in the diagnosis and further study of the frequency and spectrum of ophthalmic symptoms, especially in children

Gender Roles on Salt Farming Practices in Western Pangasinan

Men and women have been compared and contrasted for years on many different topics and on different places. Today, regardless certain behaviors both can almost do the same activities. This study aimed to determine the gender roles on salt farming practices in Western Pangasinan , the benefits from salt farming and some problems encountered by the farmers. The study made use of the descriptive survey research design. Respondents were selected through simple random sampling technique employing questionnaires to collect the needed data. Frequency, percentage, average weighted mean and t-test were used for data analysis. A total of 132 respondents (73 males and 59 females) were interviewed from salt farms situated in Alaminos City, Dasol, Bani and BolinaoPangasinan. Results showed that 34.84% of the respondents are working in the farm for almost 11 to 15 years now, that aside from salt farming 25.75% go for fishing during rainy season.. Findings also revealed that male salt farmers (AWM=3.83) in Western Pangasinan conduct salt bed preparation more frequently than female (AWM=2.69) salt farmers. On the other hand, salt farming practices of the male (AWM=3.74) and female (AWM=2.89) salt farmers are not significantly different. Hence, male and female salt farmers in Western Pangasinan have similar salt farming practices. Most of the male and female salt farmers were benefited because they were able to send their children to their college/vocational education and they were able to deliver salt to other places and that some of them were able to put up a warehouse. It is therefore recommended that in order to have a continuous salt production a technology which help salt farmers will be created.

Model Updating of a Hydraulic Chain Oscillator

A hydraulic system in form of a chain oscillator has been set up, measured and described by a mathematical model in the frequency domain. By analysing the hydraulic circuit, it is possible to derive a suitable mathematical model, with the focus on keeping it as simple as possible, but still representing all the important properties. Unknown system parameters are identified with the help of a two-step procedure using a non-linear optimization task. Excited hydraulically, by adjusting the flow rate, the pressures in this setup are measured. From this data, frequency responses between flow rate and the pressures can be calculated, which are used to validate the mathematical model and the identification strategy. Different system configurations were investigated to further confirm the validity of the model and the identification methodology.

Do we eat what we buy? Relative validity of grocery purchase data as an indicator of food consumption in the LoCard study

The validity of grocery purchase data as an indicator of food consumption is uncertain. This paper investigated 1) the associations between food consumption and grocery purchases using automatically accumulated purchase data, and 2) whether the strength of the associations differed in certain sub-populations. The participants filled in a food frequency questionnaire (FFQ), and a major Finnish retailer issued us with their loyalty-card holders grocery purchase data covering the 1- and 12-month periods preceding the FFQ. We used gamma statistics to study the association between thirds/quarters of FFQ and grocery purchase data (frequency/amount) separately for 18 food groups among the 11,983 participants. Stratified analyses were conducted for subgroups based on gender, family structure, educational level, household income and self-estimated share of purchases from the retailer. We also examined the proportion of participants classified into the same, adjacent, subsequent and opposite categories using the FFQ and purchase data. The gammas ranged from 0.12 (cooked vegetables) to 0.75 (margarines). Single households had stronger gammas than two-adult families, and participants with >60% of purchases from the retailer had stronger gammas. For most food groups, the proportion of participants classified into the same or adjacent category was >70%. Most discrepancies were observed for fresh/cooked vegetables, berries, and vegetable oils. Even though the two methods did not categorize all food groups similarly, we conclude that grocery purchase data are able to describe food consumption in an adult population, and future studies should consider purchase data as a resource-saving and moderately valid measure in large samples.
