Onečišćenje tla kao posljedica odlaganja neopasnog otpada iz procesa proizvodnje čelika
Investigated was the soil at an old metallurgical landfill site of CMC Sisak Ltd. which has been exposed to the direct influence of metallurgical nonhazardous waste for many years. Concentrations of heavy metals (Cd, Cr, Cu, Hg Ni, Pb, and Zn) after extraction in aqua regia were determined. Heavy metal concentrations, except Hg, were determined by inductively coupled optical emission spectrometry and inductively coupled plasma mass spectrometry (ICP-OES, ICP-MS). Concentration of Hg was determined by atomic absorption spectrometry.
Our objective was to assess the pollution level according to the potentially unacceptable risk limit levels for industrially used soil prescribed by the Croatian Soil Monitoring Program, and levels permitted by some EU member countries.
The results of heavy metal concentrations in composite samples of landfill soil were also compared with the results obtained from the reference sample taken in the nearby park, outside the battery limits. The obtained results qualify the analysed landfill soil as contaminated with Cu according to the legislation of all observed EU countries, with Cd according to the legislation of Italy, Poland, and Belgium (Wallonia), and with Cr according to the legislation of Finland and Poland. To allow future use of the landfill certain measures of soil treatment will be necessary.Ispitano je tlo starog metalurškog odlagališta tvornice CMC Sisak d. o. o., koje je dugi niz godina bilo izloženo različitim utjecajima neštetnog metalurškog otpada. Sadržaj teških metala Cd, Cr, Cu, Hg, Ni, Pb i Zn u tlu određen je u uzorcima tla nakon njihove ekstrakcije metala zlatotopkom. Određivanje sadržaja svih navedenih metala osim žive provedeno je metodom optičke emisijske spektrometrije induktivno vezane plazme (ICP-OES), dok je sadržaj žive određen spektrometrijom atomske apsorpcije (AAS) primjenom hidridne tehnike.
Da bi se procijenila razina onečišćenja tla, napravljena je usporedba rezultata sadržaja teških metala u analiziranim uzorcima tla s propisanim vrijednostima za potencijalno neprihvatljiv rizik za tlo upotrebljavano u industriji prema Programu trajnog motrenja tla Republike Hrvatske kao i prema propisanim vrijednostima u nekim zemljama EU. Rezultati određivanja sadržaja teških metala u kompozitnim uzorcima tla uspoređivani su s njihovim koncentracijama u referentnom uzorku tla uzetom s prostora obližnjeg parka, izvan tvorničkog kruga. Dobiveni rezultati svrstavaju analizirano tlo s odlagališta kontaminiranim prema propisima svih promatranih zemalja EU-a s bakrom, Italije i Poljske s kadmijem i Belgije (Valonija), Finske i Poljske s kromom. Za buduću upotrebu tla u istu svrhu moraju se poduzeti odgovarajuće mjere
Sukob radnih i obiteljskih uloga i zadovoljstva u medicinskih sestara u Hrvatskoj s različitim sustavima smjenskoga rada
The objective of this study was to examine the perception of conflict between work and family roles and job, family, and life satisfaction among nurses in Croatia. One hundred and twenty-nine nurses (married mothers) working in hospitals in Zadar, Šibenik, and Split were divided in four groups according to their worktime schedule. The participants completed a survey, which included a set of sociodemographic-type questions, questions about the level and allocation of family responsibilities between spouses, and scales measuring the perceived negative effects of worktime, psychological demands of the work, work-family conflict, and semantic differential scales for measuring the affective and cognitive-evaluative component of job, family, and life satisfaction. This was the first study in Croatia to deal with work-family conflict among nurses or workers with different shift systems. The results of this study indicate that nurses working morning shifts only experienced less conflict between work and family than other groups of nurses, who worked the morning, afternoon, and the night shift. The cognitive-evaluative component of job satisfaction was the highest among morning shift nurses and the lowest in nurses who worked 12-hour shifts, while the affective component of life satisfaction was the lowest in nurses working irregular and backward rotated shifts. These results confi rm that shiftwork makes the work-family role conflict even worse. They also support the view that the type of shift rotation matters.Cilj je ovoga istraživanja bio ispitati percepciju sukoba između radnih i obiteljskih uloga i radno, obiteljsko i životno zadovoljstvo kod medicinskih sestara s obzirom na različite vrste organizacije radnoga vremena. 129 udatih medicinskih sestara majki koje rade u bolnicama u Zadru, Šibeniku i Splitu podijeljeno je u 4 skupine s obzirom na vrstu organizacije radnoga vremena. Sudionice su ispunile upitnik koji je uključivao set pitanja sociodemografskoga tipa, pitanja o količini i raspodjeli obiteljskih odgovornosti među supružnicima i skale koje mjere percipirane negativne efekte radnoga vremena, psihološke zahtjeve posla, sukob između radne i obiteljske uloge te skale semantičkoga diferencijala za mjerenje afektivne i kognitivnoevaluativne komponente radnog i obiteljskog zadovoljstva i života općenito. Ovo je prvo istraživanje provedeno u Hrvatskoj u kojem je ispitivan sukob radne i obiteljske uloge kod medicinskih sestara ili općenito radnika s različitim sustavima smjenskoga rada. Rezultati pokazuju da sestre koje rade u stalnim jutarnjim smjenama doživljavaju manje sukoba zbog ometajućih utjecaja rada na obitelj od grupe medicinskih sestara koje su radile u tri smjene (u koje je uključena noćna smjena). Kognitivno-evaluativna komponenta zadovoljstva poslom bila je najviša kod medicinskih sestara s jutarnjim smjenama, a najniža kod onih koje su radile u 12-satnim smjenama. Afektivna komponenta zadovoljstva životom bila je najniža kod medicinskih sestara koje su radile u iregularnim i unatrag rotiranim smjenama. Ovi su rezultati dodatan pokazatelj različitih i više ili manje negativnih efekata smjenskoga rada na sukob između radnih i obiteljskih uloga te dodatno upozoravaju na važnost uzimanja u obzir vrste rotacije smjena
Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age.
The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.

Paleogeographic evolution of the Southern Pannonian Basin: 40Ar/39Ar age constraints on the Miocene continental series of notthern Croatia
The Pannonian Basin, originating during the
Early Miocene, is a large extensional basin incorporated
between Alpine, Carpathian and Dinaride fold-thrust belts.
Back-arc extensional tectonics triggered deposition of up to
500-m-thick continental fluvio-lacustrine deposits distributed
in numerous sub-basins of the Southern Pannonian
Basin. Extensive andesitic and dacitic volcanism accompanied
the syn-rift deposition and caused a number of
pyroclastic intercalations. Here, we analyze two volcanic
ash layers located at the base and top of the continental
series. The lowermost ash from Mt. Kalnik yielded an
40Ar/39Ar age of 18.07 ± 0.07 Ma. This indicates that the
marine-continental transition in the Slovenia-Zagorje
Basin, coinciding with the onset of rifting tectonics in the
Southern Pannonian Basin, occurs roughly at the Eggenburgian/
Ottnangian boundary of the regional Paratethys
time scale. This age proves the synchronicity of initial
rifting in the Southern Pannonian Basin with the beginning
of sedimentation in the Dinaride Lake System. Beside
geodynamic evolution, the two regions also share a biotic
evolutionary history: both belong to the same ecoregion,
which we designate here as the Illyrian Bioprovince. The
youngest volcanic ash level is sampled at the Glina and
Karlovac sub-depressions, and both sites yield the same
40Ar/39Ar age of 15.91 ± 0.06 and 16.03 ± 0.06 Ma,
respectively. This indicates that lacustrine sedimentation in
the Southern Pannonian Basin continued at least until the
earliest Badenian. The present results provide not only
important bench marks on duration of initial synrift in the
Pannonian Basin System, but also deliver substantial
backbone data for paleogeographic reconstructions in
Central and Southeastern Europe around the Early–Middle
Miocene transition
Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age
Abstract
The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset – with data collected between 2020 and 2022 – to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research
Exposure and connectedness to natural environments: An examination of the measurement invariance of the Nature Exposure Scale (NES) and Connectedness to Nature Scale (CNS) across 65 nations, 40 languages, gender identities, and age groups
Detachment from nature is contributing to the environmental crisis and reversing this trend requires detailed monitoring and targeted interventions to reconnect people to nature. Most tools measuring nature exposure and attachment were developed in high-income countries and little is known about their robustness across national and linguistic groups. Therefore, we used data from the Body Image in Nature Survey to assess measurement invariance of the Nature Exposure Scale (NES) and the Connectedness to Nature Scale (CNS) across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). While multi-group confirmatory factor analysis (MG-CFA) of the NES supported full scalar invariance across gender identities and age groups, only partial scalar invariance was supported across national and linguistic groups. MG-CFA of the CNS also supported full scalar invariance across gender identities and age groups, but only partial scalar invariance of a 7-item version of the CNS across national and linguistic groups. Nation-level associations between NES and CNS scores were negligible, likely reflecting a lack of conceptual clarity over what the NES is measuring. Individual-level associations between both measures and sociodemographic variables were weak. Findings suggest that the CNS-7 may be a useful tool to measure nature connectedness globally, but measures other than the NES may be needed to capture nature exposure cross-culturally
