Prisoners' Perception of Treatment: A Pilot Study in Serbian Prisons
No full textThe paper focuses on prisoners' perception of the quality of treatment in Serbia. The study took place in all six prisons in the Vojvodina region of the Republic of Serbia, where surveying was conducted in 2020. The sample consists of 237 prisoners from open, semi-open, and closed prison regimes. The results of regression analyses showed that prisoners' perception of the quality of treatment in Serbian prisons is influenced by their satisfaction with prison workers, perception of fairness in life, and the environment in which they grew up. Perception of fairness in life was the strongest predictor of prisoners' perception of the quality of treatment, followed by satisfaction with prison workers. Overall findings suggest that prisoners' outlook on fairness in life and the quality of relations between them and prison workers are the essential components in the treatment process, which should be considered in studying resocialisation of prisoners. In conclusion, the significance of these findings for the treatment of prisoners is discussed
Local self-government in a crisis caused by the Covid-19 pandemic: the case of Serbia
No full textThis research examined whether there is an elaborate system of protocols, protection, and prevention in place at the local self-government level in the event of a crisis caused by an epidemic or pandemic. The core idea of this paper was to evaluate the protocol's effectiveness at the local self-government. Analysis was conducted using responses of 16 local self-government authorities. During a crisis caused by an epidemic/a pandemic of infectious illnesses, surveys were done as a cross-section documenting and detecting the current state of local self-government functioning. Methods used in the study are defining the objectives of the research, conceptualization, analysis of legal regulations, economic analysis, and decomposition of the problem. Key results and arguments of this paper expanded existing research thus there are only certain empirical data from areas that have been affected by the infectious disease caused by the epidemic/pandemic. Data was collected, processed, and systematized to serve in model formulation. As a brief conclusion, this study suggested protocol effectiveness at the local self-government level representing the idea that emergency and crisis management should be organized to preserve the health and livelihood of the population in the area affected by the pandemic of infectious diseases and thus enable the functioning of economic activities and society as a whole
Species-Level Differences in Osmoprotectants and Antioxidants Contribute to Stress Tolerance of Quercus robur L., and Q. cerris L. Seedlings under Water Deficit and High Temperatures
No full textThe general aim of this work was to compare the leaf-level responses of different protective components to water deficit and high temperatures in Quercus cerris L. and Quercus robur L. Several biochemical components of the osmotic adjustment and antioxidant system were investigated together with changes in hormones. Q. cerris and Q. robur seedlings responded to water deficit and high temperatures by: (1) activating a different pattern of osmoregulation and antioxidant mechanisms depending on the species and on the nature of the stress; (2) upregulating the synthesis of a newly-explored osmoprotectant, dimethylsulphoniopropionate (DMSP); (3) trading-off between metabolites; and (4) modulating hormone levels. Under water deficit, Q. cerris had a higher antioxidant capacity compared to Q. robur, which showed a lower investment in the antioxidant system. In both species, exposure to high temperatures induced a strong osmoregulation capacity that appeared largely conferred by DMSP in Q. cerris and by glycine betaine in Q. robur. Collectively, the more stress-responsive compounds in each species were those present at a significant basal level in non-stress conditions. Our results were discussed in terms of pre-adaptation and stress-induced metabolic patterns as related to species-specific stress tolerance features
Employee job satisfaction as an element of the quality of work life
No full textIn this paper, the authors aimed to examine the relationship between the process of employee job satisfaction and the quality of work life. The main hypothesis, which is confirmed in the paper, is that there is a statistically significant correlation between the elements of job satisfaction and the quality of work life. Based on the suggested hypothesis, the main objective of the paper was to identify the concerns within the job satisfaction processes in the organizations where the research was conducted. The research involved 127 respondents who are employed at all three management levels in the organization (top management, middle management and the first-line management) in 86 business entities in the Rasina District. For the purpose of implementing this research, a questionnaire was used and its results were subsequently processed by using several statistical methods. The results of the research indicate, among other things, the concerns in the job satisfaction process, which are the basis for measuring and improving the quality of work life
Influence of foliar nutrition on yield and yield components of durum wheat (triticum durum desf.) Grown in system of organic production
No full textThis paper examines the effect of foliar nitrogen nutrition on seven durum wheat genotypes produced according to the principles of organic production. The experiments were performed during two growing seasons on organic farm in Cacak, Serbia. Three different N fertilization strategies have been compared: T1-control without N application after the stem elongation stage; T2-foliar N fertilization at the beginning of heading, one spray with 0.3% organic fertilizer Trainer (5% N and 31% amino acids); T3-foliar N fertilization in both stages, heading and anthesis with 0.3% organic fertilizer Trainer (5% N) each. Analysis of grain yield and yield components (number of spikes m(-2), number of grains per spike and thousand grain weight (TGW) was performed. The number of spikes per square meter, number of grains spike-1, TGW, and grain yield significantly increased (P LT = 0.01) with different levels of fertilizers. Foliar fertilization had a significant effect on yield in both growing seasons. Grain yield, on average for all genotypes and years after spraying were 22% (one N treatment), and 54% (two N treatments) higher than in the control. Grain yield was about 26% higher in two N treatments than in one N treatment. Grain yield was positively correlated with other traits (TGW, number of spikes m(-2) and number of grains/spike)
Praćenje odgovora hrasta lužnjaka (Quercus robur L.) na sušu analizom antioksidativnog sistema
No full textThe influence of different groundwater table depths on pre-dawn water potential (PWP), soil moisture content and antioxidant activity (FRAP, RSC against DPPH·, NO and ABTS radicals) of adult pedunculate oak (Quercus robur L.) trees was assessed in three managed stands (localities 1-3) and one unmanaged (locality 4 - forest reserve). The study sites were located within single forest complex at different distances from the Sava riverbed. The measurements were performed during July 2015, when the first evidence of drought was evidenced. We hypothesised that the trees at locations farther from the river would be more drought-stressed due to lower groundwater depth and will show higher antioxidant capacity. Indeed, trees at localities 2 and 3 were more drought-stressed as compared to trees at locations 1 and 4, as indicated by the PWP results. Since antioxidant capacity can be directly correlated to drought tolerance, the present results
indicate a higher antioxidant capacity in leaf extracts from locality 3, but also good oxidative adaptation in leaf extracts from locality 4, where the obtained values for almost all examined antioxidant tests were without statistically significant differences compared to those on locality 3. Obtained results may help to explain differences in biochemical responses to water deficit stress of pedunculate oak trees from different microsites within the single forest complex and provide us
valuable information about intra-species drought resistance. Therefore, this can be an important tool for the improvement of breeding strategies and artificial regeneration plans for pedunculate oak in dry lowland regions.U ovom radu, procenjen je uticaj različitih dubina podzemnih voda na vodni potencijal lista (PWP), sadržaj vlage u zemljištu i antioksidativnu aktivnost (FRAP, inhibicija DPPH,·NO i ABTS radikala) odraslih stabala hrasta lužnjaka (Quercus robur L.) u tri gazdovne sastojine (lokaliteti 1-3) i u jednoj neuređenoj (lokalitet 4 – šumski rezervat). Lokacije istraživanja su se nalazile u okviru jedinstvenog šumskog kompleksa na različitim udaljenostima od korita Save. Merenja su obavljena tokom jula 2015. godine, kada su zabeleženi prvi dokazi o suši. Pretpostavili smo da će drveće na lokacijama
udaljenim od reke biti pod većim sušnim stresom zbog manje dubine podzemne vode i da će pokazati veći antioksidantni kapacitet. Zaista, drveće na lokalitetima 2 i 3 bilo je pod većim stresom od suše u poređenju sa drvećem na lokacijama 1 i 4, kao što pokazuju rezultati PWP. Obzirom da antikosidativni kapacitet može biti direktno povezan sa tolerancijom na sušu, sadašnji rezultati ukazuju na veći antioksidativni kapacitet u ekstraktima listova sa lokaliteta 3 ali i na dobru
oksidativnu adaptaciju listova sa lokaliteta 4, gde su dobijene vrednosti za skoro sve ispitivane antioksidativne testove bile su bez statistički značajnih razlika u odnosu na vrednosti dobijene na lokalitetu 3. Dobijeni rezultati mogu pomoći da se objasne razlike u biohmeijskim odgovorima na stres vodnog deficita kod stabala hrasta lužnjaka sa različitih mikrolokacija u okviru jedinstvenog šumskog kompleksa i daju nam dragocene informacije o intra-specijskoj otpornosti na sušu. Stoga,
ovo može biti važna alatka za unapređivanje strategije oplemenjivanja i planova veštačke regeneracije hrasta lužnjaka u suvim ravničarskim regionima
Response of two tomato cultivators to Trichoderma spp. assessed by non-destructive measurements
No full textBiofertilizers have great potential to improve crop yields through environmentally save mechanisms. Fungi of the genus Trichoderma, as potential components of biofertilizers, have a positive effect on plant growth and inhibit the growth of pathogenic microorganisms through several antagonistic mechanisms. In this study, commercially available tomato genotypes (Narvik and Gruzanski zlatni) and strains of two Trichoderma species (T. afroharzianum SZMC 25231 and T. rodmanii SZMC 25217) were selected to examine the effects of Trichoderma spp. on morpho-physiological parameters of tomato plants grown under organic production system.
The experiment was conducted in a randomized block design under greenhouse conditions. In total, 15 plants of two tomato cultivars per treatment were transplanted in soil: NC – control Narvik, GZC – control Gruzanski zlatni, NT1 – T. afroharzianum; NT2 – T. rodmanii; GZT1 – T. afroharzianum; GZT2 - T. rodmanii. The suspensions of Trichoderma isolates were applied in the root zone of tomato plants in the phase of four established leaves. Measurements of relative chlorophyll (Chl), flavonol (Flav) and anthocyanin (Ant) content were performed in vivo on fully developed leaves of the tomato plants using Dualex optical sensor (Force-A, Orsay, France). NBI (Nitrogen Balance Index) was calculated as Chl/Flav ratio. Plant height was measured as a plant growth parameter. Measurements were performed once per week during 35 days of plant growth (5 weeks) and conducted in 10 replications on 10 plants per treatment.
Compared to the control, significant increase of Chl and Flav content was observed on genotype GZ after treatment with both Trichoderma species in the 3rd and 4th week, which resulted in decreased value of the NBI. Also, for the same genotype, Trichoderma positively affected plant height. On the other hand, combination of Trichoderma and genotype Narvik hasn’t showed stimulative effect on examined morpho-physiological parameters. These results indicated genotype-species dependence of tomato-Trichoderma interaction.
The obtained results indicate that non-destructive measurements with Dualex sensor could serve as starting point to better understand plant responses to Trichoderma presence
Evaluation of gene effects in the grain yield and kernel oil content in maize (Zea mays l.)
No full textSelection of the best breeding technique for the development of new maize
hybrids is based on knowledge of gene effects type responsible for the
expression of quantitative traits. Thus, the goal of this study was to evaluate
gene effects on the grain yield, as the most important agronomic trait, as
well as for kernel oil content. one of the major characteristics of maize
quality.
Genetic material used for the determination of gene effects consisted of
four inbred lines: 1109/1V NS, 56811 NS, 922 NS and A-l. Inbred line
1109/1V NS is high oil inbred line, and 568/11 NS, 922 NS A-1 are lines
with a different type of seed: dent, semi-dent and flint, respectively. Six
basic generations were produced: parental inbred lines (Pi, Pa), first and
second filial generations (Fy, F2) and backcross generations (BC), BC2).
Two years experiment was performed at the experimental field of the
Institute of Field and Vegetable Crops, Novi Sad, Serbia (Rimski Sangevi)
using a completely randomized design with eight replicates. Evaluation of
gene effects was performed by generation mean analysis.
Obtained results indicated that dominant gene effect had a higher influence
than additive in inheritance of the grain yield. The significant presence of
duplicate type of epistasis was recorded in all test-cross combinations. For
kernel oil content dominance was more important than additive gene action
for almost all studied test-crosses. Additive gene effect was higher than
dominance only for hybrid 1109/IV NS = 56811 NS. Morcover, a
significant presence of duplicate type of cpistasis also was detected for
kernel oil content.
The significant role of the dominant gene effect in the inheritance of grain
vield and kernel oil content in almost all test-cross combinations indicates that inbreding-hybridization method is a useful method for the development of
better hybrids
Циркуларна економија и запошљавање у Европској унији
No full textМонографија Циркуларна економија и запошљавање у Европској унији, резулат је дугогодишњег истраживања политика рада и запошљавања на подручју Европске уније (ЕУ), као и потребе да се привредни системи земаља чланица, али и земаља кандидата за чланство у ЕУ ускладе са циљевима одрживог развоја. Стање које је планету, а пре свега човечанство затекло крајем 2019. године, дало је времена да се запитамо да ли као економска бића задовољавајући потребе, прекомерно експлоатишемо ограничене природне ресурсе, те се из тога јавила идеја ауторке да у свом домену истраживања политике рада и запошљавања Европске уније и Србије, ову публикацију посвети циркуларној економији, која кореспондира и са предлозима ЕУ у циљу опоравка од ефеката изазваних пандемијом корона вируса. Кроз поглавља: циркуларна економија, циркуларна економија у Европској унији и запосленост у секторима циркуларне економије Европске уније, у монографији је дата анализа ове материје, актуелне како на глобалном, нивоу ЕУ, тако и земаља кандидата за чланство у ЕУ. Монографија се завршава препорукама ауторке, након чега је дат списак доступне литературе, коришћене и консултоване за израду публикације, као и аутоцитата из радова објављених из области одрживог развоја. Питање Брегзита и АП Косова и Метохије неће бити предмет разматрања у овој публикацији, због својих комплексности, а према релевантним подацима званичне статистике. Велика Британија биће представљена у оквиру другог поглавља, још увек као саставни део ЕУ, обзиром да се у анализи и посматра период пре изласка ове чланице из Уније (подaци су за период 2008-2018 године). Прикупљање података за издраду монографије, трајало је од пролећа 2020 године, до краја 2021 године
