Rad je dio projekta Specifična obilježja obitelji u riziku: doprinos razvoju kompleksnih intervencija, koji se provodi na Edukacijsko-rehabilitacijskom fakultetu Sveučilišta u Zagrebu, a financiran ...je od Hrvatske zaklade za znanost u okviru natječaja Istraživački projekti 2014. Cilj rada je istražiti, predstaviti i prodiskutirati različita razumijevanja kompleksnih intervencija i uz njih vezanih konstrukta i teorijskih pristupa. Krajnji cilj tog predstavljanja je konstruiranje operacionalne definicije koje će se u projektu koristiti. Pregled literature obuhvatio je radova koji se bave s jedne strane kompleksnim potrebama, problemima i populacijama, a s druge strane kompleksnim sustavima i intervencijama u području odgoja i obrazovanja, socijalne skrbi, pravosuđa i zdravstva. Nakon analize postavljene su operacionalne definicije pojmova kompleksne (indiviualne i obiteljske) potrebe i kompleksne intervencije te su generirane smjernice za planiranje i provedbu istraživačkog dijela projekta.
This article is part of the project Specific characteristics of families at risk: contribution to complex interventions planning which is conducted at The University of Zagreb, Faculty of Education and Rehabilitation Sciences. The project is fully financially supported by Croatian Scientific Foundation under the Research Projects 2014. The aim of this paper is to find out, present and discuss different meanings and understandings of complex interventions, as well as theories and models they are based on. The final purpose of that presentation is to construct operational definition of complex interventions that is going to be used in this project. Literature on complex needs, problems and populations was reviewed parallel to literature covering complex intervention and complex interventional systems in the domain of education, health, especially mental health, social welfare and justice. After that, operational definitions of the notions of complex (individual and family) needs and complex interventions, as well as recommendations for planning and implementing research procedure were presented.
U cilju procjene stavova studenata medicine u odnosu na sudjelovanje vulnerabilnih subjekata u kliniÄkim ispitivanjima, proveli smo studiju presjeka (N = 174, studenti dodiplomskih studija ...Medicinskog fakulteta, Univerziteta u Beogradu). Studija presjeka provedena je tijekom jednog dana, na sluÄajno odabranim uzorcima studenata 3. godine (95/493 studenata) i 6. godine (79/510 studenata). Ukupno je odgovoreno na 83 % postavljenih pitanja. Rezultati studije pokazali su da studenti naÅ¡eg fakulteta uglavnom nisu voljni sudjelovati kao dobrovoljci u kliniÄkim ispitivanjima, niti raditi u nehigijenskim romskim naseljima. Studenti su naglasili važnost dobivanja pristanka i djeteta i roditelja za sudjelovanje u kliniÄkom ispitivanju. Kada su u pitanju ispitivanja novih lijekova na populaciji starijih dementnih bolesnika, većina ispitanika smatra da informirani pristanak treba biti sliÄan pristanku za bilo koju drugu populaciju. U zakljuÄku, tekući medicinski kurikulum treba biti viÅ¡e usmjeren na procjenu sigurnosti lijekova u vulnerabilnim skupinama. Posebno je potrebno unaprijediti rad s pripadnicima marginaliziranih skupina (npr. dodatna edukacija, posjeti nehigijenskim romskim naseljima i zajedniÄki projekti).
Abstract The paper summarizes current knowledge on the population size, habitat, conservation status and conservation measures for the White-backed Woodpecker Dendrocopos leucotos in Slovenia. The ...species is an extremely rare forest specialist species. It inhabits mostly Dinaric beech Fagus sylvatica forests from Trnovski gozd, Nanos, Javorniki Mts and Mt Snežnik to the Kočevsko region and Gorjanci Mts. The species is also present in the Zasavje region and Mt Boč. The majority of the population (80%) inhabits the altitudinal belt between 700 and 1400 m a.s.l. The size of the Slovenian breeding population is currently estimated at 100-150 breeding pairs. Using the new survey playback method, we expect to find the species at additional sites. The highest densities were recorded on Mt Snežnik (0.7 breeding pairs/km 2 in the Zatrep - Planinc forest reserve, 0.6 breeding pairs/km 2 at Gomance) and in the Gorjanci Mts (0.6-0.9 breeding pairs/km 2 in the Kobile forest reserve). The species inhabits beech and mixed forests with an important percentage of dead trees. The volume of dead trees was measured only at few sites inhabited by the species and ranged from 42 to 283 m 3 /ha. Signs of foraging were detected mainly on beech snags and stumps; all nests were found in upright beech snags. In Slovenia, the species is threatened by the low percentage of dead deciduous trees in forests, the construction of new forest roads, the increased annual timber harvest and a weak network of forest reserves. The proposed conservation measures include increasing the amount of dead deciduous trees in managed forests, increasing the area of forest reserves and halting the construction of new forest roads.
The aim of the presented investigation was to estimate the genetic diversity, and correlation analysis among yield and quality traits in twenty local maize populations. The experiment was based on ...randomized complete block design (RCBD) with three replications. In the study we compared grain yield, and quality traits such as protein, oil and starch content in grain. The results showed that there were significant differences among populations. The overall mean grain yield was 79.33 g plant-1 with the highest grain yield in population GBK-7 (105.13 g plant-1). The protein and oil contents ranged between 11.02 to 13.02% and 2.56 to 5.57%, respectively. The starch content varied from 68.58 to 70.92%. The first two canonical discriminant functions were significant at p < 0.01. It is important to point out the great relevance of the first two discriminant functions justifying 95.80% of the variability among populations. There were also big differences regarding phenotypic correlations. The study suggests that the quality traits are phenotypically and genotypically highly variable and therefore very useful for breeding process
Namen raziskave je bil proučiti genetsko raznolikost in korelacije med pridelkom in nekaterimi kakovostnimi lastnostmi zrnja (vsebnost beljakovin, olja, škroba in pepela v zrnju) 20 lokalnih populacij koruze na Kosovem. Poskus je bil postavljen po metodi naključnih blokov v 3 ponovitvah. Za vse lastnosti so ugotovljene statistično značilne razlike med proučevanimi populacijami. Povprečni pridelek zrnja vseh populacij je znašal 79,33 g rastlino-1, najvišji pridelek je imela populacije GBK-7 (105,13 g rastlino-1). Vsebnost beljakovin se je gibala med 11,02 in 13,02 %, olja med 2,56 in 5,57 % in škroba med 68,58 in 70.92 %. Z diskriminantno analizo je ugotovljeno, da sta prvi dve komponenti pojasnili 95,80 % varabilnosti med populacijami. Med nekaterimi lastnostmi so za proučevane populacije ugotovili signifikantne korelacije. Glede na veliko genetsko variabilnost smatramo, da bi proučevane lokalne populacije lahko bile koristne v nadaljnjem žlahtnjenju genotipov koruze z dobrimi kakovostnimi lastnostmi zrnja.

Kao testni primjer uzet je problem predviđanja izlaznih vrijednosti rješenja ...parametarski ovisne diferencijalne jednadžbe prvog reda. Dobiveni rezultati potvrđuju sposobnost neuronske mreže da brzo i pouzdano reproducira tražene vrijednosti bez potrebe rješavanja same jednadžbe.
Cilj je ovoga rada bio utvrditi proizvodni potencijal i veličinu populacije ugroženih pasmina ovaca u Republici Hrvatskoj i Crnoj Gori. U Republici Hrvatskoj se uzgaja 9 izvornih pasmina ovaca od ...kojih je samo jedna visoko ugrožena (dubrovačka ruda: 702 grla), a 5 su potencijalno ugrožene (cigaja, rapska ovca, creska ovca, istarska ovca i krčka ovca). Najveću tjelesnu masu i veličinu legla ima cigaja (74,64 kg i 1,21), a najmanju krčka ovca (35,44 kg i 1,06). Najviše mlijeka u laktaciji proizvedu istarska ovca i cigaja, a najmanje creska ovca i rapska ovca. Završni dnevni prirast i prosječni dnevni prirast muške janjadi u field uvjetima bili su najveći u cigaje (307 g i 35,77 kg), a najmanji u janjadi krčke ovce. U Crnoj Gori se uzgaja 6 izvornih pasmina ovaca. Zetska žuja je najmalobrojnija pasmina ovaca u Crnoj Gori i ima status kritično ugrožene pasmine (oko 150 grla), dok su pivska pramenka, sora i ljaba potencijalno ugrožene pasmine. Najbolje proizvodne rezultate (mliječnost) imaju pivska i bardoka (106,8 i 110 kg), a najlošije zetska žuja (49,6 kg). Proizvodni potencijal ugroženih pasmina ovaca u obje zemlje ukazuje na opravdanost značaj¬nijih ulaganja u širenje njihovih uzgoja, što će pridonijeti i podizanju profitabilnosti uzgoja kao i povećanju interesa za navedene pasmine ovaca.
The most common form of the Brassica napus L. is oilseed rape. Because of its physical characteristics the seed is very mobile and therefore disposed to spillage. Uncontrolled seed loss represents ...the potential for the appearance of volunteer and feral populations of B. napus inside and outside production areas; B. napus seed remains viable in the soil for several years. The appearance dynamics of these plants is dependent on the soil seed bank potential and complex interactive characteristics of the genotype seeds and soil and agro-climatic factors. The presence of undefined pollinating resources originated from soil seed bank in the nature presents the potential for spontaneous intra- and inter-species pollination of B. napus reflected also in its genetic structure.
