Razlog za pisanje prispevka je pomen uvedbe statusa pooblaščenega gospodarskega subjekta, ki je zagotavljanje varnosti celotne dobavne verige in njenih posameznih členov – gospodarskih subjektov. Cilj prispevka je predstavitev procesa pridobivanja statusa pooblaščenega gospodarskega subjekta z vidika zahtev, ki jih mora gospodarski subjekt izpolnjevati, da ustreza merilom za podelitev statusa, s poudarkom na varnostnih in varstvenih zahtevah

Skrito nasilje na delovnem mestu - med zanikanjem in trpljenjem

Razlog za pisanje prispevka je dejstvo, da je psihično nasilje (mobbing/bullying) dandanes postalo realnost marsikaterega zaposlenega in delovnih okolij povsod po svetu. Ima resne in uničujoče posledice, tako za žrtev kot tudi za ostale sodelavce, celotno organizacijo in družbo nasploh. Cilj prispevka je opisati fenomenologijo psihičnega nasilja na delovnem mestu in poudariti resnost posledic mobbinga na vseh ravneh

Quantum limit transport and destruction of the Weyl nodes in TaAs

Weyl fermions are a new ingredient for correlated states of electronic matter. A key difficulty has been that real materials also contain non-Weyl quasiparticles, and disentangling the experimental signatures has proven challenging. We use magnetic fields up to 95 tesla to drive the Weyl semimetal TaAs far into its quantum limit (QL), where only the purely chiral 0th Landau levels (LLs) of the Weyl fermions are occupied. We find the electrical resistivity to be nearly independent of magnetic field up to 50 tesla: unusual for conventional metals but consistent with the chiral anomaly for Weyl fermions. Above 50 tesla we observe a two-order-of-magnitude increase in resistivity, indicating that a gap opens in the chiral LLs. Above 80 tesla we observe strong ultrasonic attenuation below 2 kelvin, suggesting a mesoscopically-textured state of matter. These results point the way to inducing new correlated states of matter in the QL of Weyl semimetals

Scale-invariant magnetic anisotropy in RuCl3_3 at high magnetic fields

In RuCl$_3$, inelastic neutron scattering and Raman spectroscopy reveal a continuum of non-spin-wave excitations that persists to high temperature, suggesting the presence of a spin liquid state on a honeycomb lattice. In the context of the Kitaev model, magnetic fields introduce finite interactions between the elementary excitations, and thus the effects of high magnetic fields - comparable to the spin exchange energy scale - must be explored. Here we report measurements of the magnetotropic coefficient - the second derivative of the free energy with respect to magnetic field orientation - over a wide range of magnetic fields and temperatures. We find that magnetic field and temperature compete to determine the magnetic response in a way that is independent of the large intrinsic exchange interaction energy. This emergent scale-invariant magnetic anisotropy provides evidence for a high degree of exchange frustration that favors the formation of a spin liquid state in RuCl$_3$.Comment: arXiv admin note: substantial text overlap with arXiv:1901.09245.

Project-based learning - area of improving the quality of school

U traženju najboljih načina za ostvarivanje ciljeva nastave, jedno od mogućih didaktičkih rješenja pronalazimo u projektnoj nastavi. Ravitz i sur. (2012) opisuju projektnu nastavu kao koncept stvaranja uvjeta u kojima učenici mogu učiti složenija znanja i vještine koja su im nepohodna za život u 21. stoljeću. Ona predstavlja brojne izazove za učitelje i škole, a poteškoće na koje nailaze pri njezinoj implementaciji su brojne. Za učinkovito rješavanje problema implementacije projektne nastave u radu škole, neophodno je omogućiti učiteljima samovrednovanje nastavnog procesa. Samovrednovanje je proces koji sustavno prati, analizira i procjenjuje uspješnost rada kako bi se trajno unaprijedila kvaliteta i stvorilo poticajno radno okruženje. U ovom je radu prikazan primjer Školskog razvojnog plana, kao sastavnog dijela procesa samovrednovanja, kojim je projektna nastava definirana kao prioritetno područje unaprjeđenja rada škole i razvojnih ciljeva koji proizlaze iz njih.In finding the best ways to accomplish learning goals one of the possible didactic solutions would be project-based learning. Ravitz et al. (2012) describe project-based learning as a concept that involves creating conditions which would help students learn more complex knowledge and skills vital for the life in the 21st century. This concept holds many challenges for both teachers and schools, and many issues arise in its implementation. The effective solution for the implementation problems of project-based learning in schools necessary involves self-evaluation of the teaching process. Self-evaluation is a process that systematically monitors, analyses and assesses the work performance in order to permanently achieve better quality and create a more productive working surroundings. This paper shows an example of a school development plan, as an integral part of the self-evaluation process, that defines the project-based learning as a priority area in improving the school processes and development goals which derive from them

Resonant torsion magnetometry in anisotropic quantum materials

Unusual behavior of quantum materials commonly arises from their effective low-dimensional physics, which reflects the underlying anisotropy in the spin and charge degrees of freedom. Torque magnetometry is a highly sensitive technique to directly quantify the anisotropy in quantum materials, such as the layered high-T$_c$ superconductors, anisotropic quantum spin-liquids, and the surface states of topological insulators. Here we introduce the magnetotropic coefficient $k=\partial^2 F/\partial \theta^2$, the second derivative of the free energy F with respect to the angle $\theta$ between the sample and the applied magnetic field, and report a simple and effective method to experimentally detect it. A sub-$\mu$g crystallite is placed at the tip of a commercially available atomic force microscopy cantilever, and we show that $k$ can be quantitatively inferred from a shift in the resonant frequency under magnetic field. While related to the magnetic torque $\tau=\partial F/\partial \theta$, $k$ takes the role of torque susceptibility, and thus provides distinct insights into anisotropic materials akin to the difference between magnetization and magnetic susceptibility. The thermodynamic coefficient $k$ is discontinuous at second-order phase transitions and subject to Ehrenfest relations with the specific heat and magnetic susceptibility. We apply this simple yet quantitative method on the exemplary cases of the Weyl-semimetal NbP and the spin-liquid candidate RuCl$_3$, yet it is broadly applicable in quantum materials research.Comment: 7 pages including 6 figures and methods sectio

Spatial control of heavy-fermion superconductivity in CeIrIn5

M.D.B. acknowledges studentship funding from EPSRC under grant EP/I007002/1.Although crystals of strongly correlated metals exhibit a diverse set of electronic ground states, few approaches exist for spatially modulating their properties. In this study, we demonstrate disorder-free control, on the micrometer scale, over the superconducting state in samples of the heavy-fermion superconductor CeIrIn5. We pattern crystals by focused ion beam milling to tailor the boundary conditions for the elastic deformation upon thermal contraction during cooling. The resulting nonuniform strain fields induce complex patterns of superconductivity, owing to the strong dependence of the transition temperature on the strength and direction of strain. These results showcase a generic approach to manipulating electronic order on micrometer length scales in strongly correlated matter without compromising the cleanliness, stoichiometry, or mean free path.PostprintPeer reviewe

Stališča policistov in državljanov do zagotavljanja varnosti v lokalnih skupnostih v Sloveniji

Main purpose of the dissertation is to compare police officers’ and citizens’ attitudes toward various aspects of local safety provision, with the emphasis on community policing, which is currently the main philosophy of policing in Slovenia. Data for the study comes from a survey administred to a sample of police officers and citizens to assess their attitudes on a broad range of issues regarding the provision of safety on the local level as related to Slovene police in general, police effectiveness in various activities, legality of police work and citizens’ willingness to cooperate with the police among others. Within the comparison between citizens’ and police officers’ attitudes, areas of the highest and the lowest degree of concordance between attitudes were identified and examined. Attitudes of police officers and citizens were found to be most dissimilar regarding legality of police work, effectiveness in protecting life, personal safety and property, general perceptions of police and effectiveness in community policing. Overall level of concordance between attitudes of both groups was found to be low. The foci of our further analysis were the factors which influence citizens’ and police officers’ attitudes toward police effectiveness in community policing. Effects of gender, age, education, fear of crime and residency characteristics on citizens’ attitudes were examined, and effects of age, education, participatory management, organizational support, job satisfaction and community support on police officers’ attitudes were examined. Results of regression analysis showed that police visibility, trust in the government, age, fear of crime and length of residency affect citizens’ attitudes toward police effectiveness in community policing, however these variables account only for 30.1 percent of the variation in citizens\u27 attitudes toward community policing. Police officers’ attitudes toward police effectiveness in community policing are affected by age, education, organizational support, job satisfaction and community support. These variables were found to account only for 28.7 percent of the variation in police officers\u27 attitudes toward community policing. Majority of the variation in both groups’ attitudes toward community policing thus remains unexplained. Suggestions for further research and policy implication are provided, focused on inclusion of additional variables into model of police officers’ attitudes and model of citizens’ attitudes. Variables found to affect citizens of both groups toward police effectiveness in community policing by the findings of present research should be taken into consideration by police administrators and local safety policy makers.Glavni cilj doktorske disertacije je primerjava stališč policistov in državljanov do nekaterih vidikov zagotavljanja varnosti na lokalni ravni, s poudarkom na policijskem delu v skupnosti, ki je bilo v Sloveniji uvedeno po letu 1990 kot del procesa demokratizacije in prenosa idej o policijskem delu z Zahoda. Glavno raziskovalno vprašanje se tako glasi: Kakšna je stopnja skladnosti med stališči policistov in stališči državljanov do zagotavljanja varnosti na lokalni ravni, s poudarkom na policijskem delu v skupnosti, ki zahteva dobršno mero sodelovanja med policisti in državljani? Primerjali smo stališča policistov in državljanov glede različnih vidikov zagotavljanja varnosti na lokalni ravni, in sicer splošen vtis o policiji in njihovem deluuspešnost policije pri varovanju življenja, osebne varnosti in lastninezakonitost policijskega delauspešnost policije pri odkrivanju in preiskovanju kaznivih dejanjuspešnost policije pri policijskem delu v skupnostipripravljenost državljanov za sodelovanje s policijousmerjenost v skupnost in tradicionalna usmerjenost. Drugi del raziskave se nanaša na proučevanje dejavnikov, ki vplivajo na stališča policistov in državljanov do policijskega dela v skupnosti. Identifikacija dejavnikov namreč omogoča vpogled v oblikovanje stališč posamezne skupine z možnostjo vplivanja na spreminjanje stališč v želeni smeri. Glavne ugotovitve doktorske disertacije se nanašajo na primerjavo stališč policistov in državljanov glede različnih vidikov zagotavljanja varnosti v lokalnih skupnostih. Stališča policistov in državljanov so v veliki meri različna, torej je stopnja skladnosti med stališči policistov in stališči državljanov do policijskega dela v skupnosti nizka. Področja, ki so s tega vidika najbolj »problematična«, so: zakonitost policijskega dela, uspešnost policistov pri varovanju življenja, osebne varnosti in lastnine, splošen vtis o policiji in njihovem delu ter uspešnost policistov pri policijskem delu v skupnosti. Na tem mestu izpostavljamo zakonitost policijskega dela, kjer so stališča policistov in državljanov najbolj neskladna. Državljani izražajo dvom v zakonitost policijskega dela, kar v praksi lahko pomeni veliko težavo, še posebej z vidika policijskega dela v skupnosti, ki temelji na sodelovanju prebivalcev njihova pripravljenost je ob upoštevanju izraženega dvoma v zakonitost policijskega dela zagotovo vprašljiv
