The study examines the relationship between media content about war violence victims and the cultivation of victim mentality within the framework of cultivation theory. Cultivation theory presupposes ...the individuals who watch a great deal of television, i. e., who are exposed to media violence for a long period of time, believe the world to be violent. Victim mentality is a psychological condition of persons who see themselves as victims of others or of the environment in which they live. Such persons feel and behave as victims even when they have not directly experienced physical or mental violence. Victim mentality can be acquired in the family or in the social or media environment. Frequent consequences of the victim mentality are defensiveness, blaming others for personal maladies and a negative stance towards others and their social environment. The main assumption of this study – that the individuals who watch a great deal of television in RS, which contains a significant amount of content about the remembrance of violence victims from previous wars, demonstrate victim traits – has been partially confirmed. The study reports the results of content analysis of the news shows for RTRS and RTVBN as well as of the survey research of RS adults on the population of greater city of Banja Luka, conducted May through July 2015. The study also considers the circumstances and consequences of this vicarious victimization of sorts.
•Preparation method had impact on differences in the compost products’ composition.•Compost products demonstrated a diverse effect on plant species’ germination.•Compost products application has a ...potential in the suppression of plant pathogens.•Green waste composting represents a promising approach in sustainable horticulture.
Besides ecological and environmental benefits of green open spaces, horticultural waste management has various environmental consequences. Green waste composting represents promising environmentally friendly alternative which gives valuable products with positive soil and plants impact. Composting products’ quality determinates their application and depends on the particular waste material and process parameters. The aim of this paper was to estimate the chemical and microbiological quality of green waste compost and compost products (compost tea, compost extract and the solid phase after extraction), and their biopotential based on germination rate, germination index and inhibition of phytopathogenic fungi growth. Higher germination rate of examined plant seeds was noticed on the solid phase after extraction, and compost extract, compared to compost, and compost tea, respectively. Plants with low germination rate grown on compost showed higher fresh and dry biomass. Compost products strongly inhibited the growth of plant pathogens Fusarium oxysporum, Rhizoctonia sp., and Pythium debaryanum. Presented results show that composted biodegradable waste from urban green spaces contribute to the plant growth and phytopathogenic fungi suppression, and thus improve the overall environmental quality.

The first experimental results of the indoor air quality in two kindergartens located in the Republic of Srpska are presented in this paper. Kindergarten representatives for the year of construction ...(old and new), building materials, and energy efficiency have been chosen. Indoor air quality measurements (air temperature, relative humidity, ventilation rate, CO2, and radon concentration) were performed during the winter of 2015/2016. Measured indoor air quality parameters are discussed and compared to the international standards BAS EN 16798-1, ASHRAE 62.1, and ISO 7730. The average measured radon concentrations for both buildings have not exceeded the level of 200 Bq/m3, but for reliable results, long-term measurement needs to be performed. The CO2 concentration in the old kindergarten fulfills the BAS EN 16798-1 requirement for Category I during 62.43% of total occupancy time, while for the new kindergarten, it is only 5.79% of full occupancy time. Results of CO2 concentration confirm that good sealing of the envelope of new buildings and user behavior (number of users and natural ventilation) does affect air quality. Furthermore, a high correlation between CO2 concentration and relative humidity in both buildings and a more considerable correlation for the new building have been observed.

Overburden waste dumps represent a huge threat to environmental quality. The reduction of their negative impact can be achieved by vegetation cover establishment. Usually, this action is complicated ...due to site-specific characteristics, such as nutrient deficiency, elevated metal concentration, low pH value, lack of moisture and lack of organic matter. Establishment of vegetation can be facilitated by inoculation with plant growth promoting bacteria (PGPB) which improve the physicochemical and biological properties of degraded substrates and make them more hospitable for plants. In this study we selected several strains based on the ability to produce ammonia, indole-3-acetic acid, siderophores and lytic enzymes, and to solubilize inorganic phosphates. This selection resulted in microbial consortia consisting of Serratia liquefaciens Z-I ARV, Ensifer adhaerens 10_ ARV, Bacillus amyloliquefaciens D5 ARV and Pseudomonas putida P1 ARV. The effects of PGPB consortia on one-year-old London plane (Platanus × acerifolia Aiton Willd.) seedlings replanted into overburden waste from Kolubara Mine Basin were examined. After seven months, inoculated seedlings were 32% higher with 45% wider root collar diameter and over 80% higher total dry biomass compared to uninoculated seedlings grown in Kolubara’s overburden. Inoculation resulted in higher amounts of total soluble proteins, higher chlorophyll and epidermal flavonoids content and higher total antioxidative capacity in the leaves. This study represents a successful search for effective PGPB strains and shows that microbial consortia have an important role in enhancing the growth of seedlings in nutrient deficient and degraded substrates such as overburden waste from open-pit coal mines. Positive response of London plane seedlings suggest that inoculation may help widening the opus of species for reforestation of post mining areas and speed up natural succession processes and recovery of degraded landscapes.
