Osobni fond Vladimir Poljak čuva se u Arhivskoj zbirci Hrvatskog školskog muzeja.The Croatian School Museum obtained a valuable donation in 1999 from the famous pedagogue Vladimir Poljak, Ph. D. donated from his wife Ilsa, son Željko and daughter Višnja, and upon the wish by doctor Poljak. The manuscripts left in the legacy contained different archival material and personal library, and were logged into Croatian School Museum entrance records under the number 24105. Library material was separated from the archival documentation and was submitted to Pedagogical library Davorin Trstenjak. Archival documentation was sorted by the international standards for the description of archival documentation and information tool was made under the title Analitički inventar Osobnog fonda HR HŠM Poljak Vladimir.
Vladimir Poljak (1920– 1998) was a teacher, pedagogue and faculty professor. He worked at the Faculty of Philosophy for thirty years; he was a member of different associations, institutions and media outside the faculty, as well as publishing councils. He received many rewards and awards for his work among which was the Life Achievement Award “Ivan Filipović”. Basic topics for scientific-research work were the questions of didactic and methodic starting points, educational system, teaching and school practice. His works were translated in many languages, and university handbook Didaktika was published in many editions (translated even in Chinese). Time range of the holdings is from 1939 to 1998, and contains manuscripts of monographs, articles, reviews, different notes, correspondence and newspaper articles collection. Following the standards of archiving the holdings were sorted according to works of V. Poljak, i.e. by the way the documents were created, therefore nine series and sixteen sub-series were created, which contain great number of documents for the history of pedagogy, and further research and advancement of education, upbringing and schools in Croatia

No full textVojaško vodenje in sestava vojaškega tima : diplomsko delo visokošolskega strokovnega študija Varnost in policijsko delo
No full textDiplomsko delo je sestavljeno iz petih delov. V prvem delu predstavljamo opredelitev problema diplomskega dela, cilje in teze, predpostavke ter uporabljene metode pri pisanju diplomskega dela. V drugem delu predstavljamo vojaško vodenje, v tretjem delu vojaški tim. V četrtem delu se osredotočamo na razpravo glede na opredelitev problema diplomskega dela in v zadnjem delu verificiramo predpostavke in povzemamo glavne ugotovitve.
Formiranje timov tako v civilnih kakor tudi v vojaških organizacijah je postalo eden ključnih načinov za povečanje učinkovitosti teh organizacij. Zato danes vse sodobne vojske koristijo timsko obliko organiziranosti za soočanje z izzivi, naj bo to v boju ali pa v mirnodobnem času. Izgradnja vojaškega tima ni lahka naloga in tima tudi ne moremo formirati čez noč. Da bi bil tim učinkovit, potrebuje za svoj razvoj čas.
Uspešen vojaški tim svoje naloge opravlja hitro, učinkovito in brez nepotrebnih medsebojnih zapletov. Značilnosti takega tima so: jasno vodenje, razdelitev vlog, usklajenost, kohezija, zaupanje in skupni cilj. Bistvo za njegovo sestavo je poznavanje podrejenih, poštenost in objektivnost pri delu z njimi, vodenje z zgledom in sprejemanje lastne odgovornosti poveljnika za stanje v enoti.
Ključni element za sestavo uspešnega vojaškega tima je vodja tima oziroma poveljnik tima, znanje in sposobnost vojaškega vodenja pa mu to omogočata. Poleg znanja in sposobnosti vojaškega vodenja pa potrebuje tudi določene osebne lastnosti in strokovna znanja, da lahko to delo opravlja. Pomembno je tudi dobro poznavanje samega sebe, izbor stila vodenja, postavljanje ciljev vojaške organizacije pred svoje lastne cilje, visok nivo odgovornosti in volja do dela.The thesis is composed of five parts. In the first part we define the problem addressed in the thesis and present the objectives and theses, assumptions and methods used in writing the thesis. In the second part we provide insight into military command and in the third part into the military team. In the fourth part we discuss the definition of the thesis problem, while in the last part we verify the assumptions and summarize the main findings.
The formation of teams in both civil and military organizations has become one of the key methods to increase the effectiveness of these organizations. Therefore, all modern armies today use the team-based form of organization to meet the challenges, whether in combat or in peacetime. Forming a military team is not an easy task and a team cannot be formed overnight. It requires time to develop and become effective.
A successful military team performs its tasks quickly, efficiently and without unnecessary mutual complications. The characteristics of such a team are: clear command, division of roles, coordination, cohesion, trust and a common goal. The essence of forming the team lies in subordinate knowledge, honesty and objectivity in dealing with them, guiding by example and adopting the commander\u27s own responsibility for the condition of the unit.
The key element in forming a successful military team is the team leader or team commander, mainly owing to his knowledge and ability of military command. In addition to the skills and abilities of military command, he should also possess certain personality characteristics and professional skills in order to perform that work. Moreover, it is very important to know oneself, select the leadership style, prioritize the goals of a military organization over personal goals, and show a high level of responsibility and desire to work
Gap inequalities for non-convex mixed-integer quadratic programs
No full textLaurent and Poljak introduced a very general class of valid linear inequalities, called gap inequalities, for the max-cut problem. We show that an analogous class of inequalities can be defined for general non-convex mixed-integer quadratic programs. These inequalities dominate some inequalities arising from a natural semidefinite relaxation
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Reliability analysis and assessment of the explosion risk in a hybrid collector
No full textDust removal from a gas stream is a common problem in many industrial processes (e.g. power, cement, steel plants, etc.). In the last decades, plant managers more and more often have had to face the necessity of improving de-dusting systems in order to meet more stringent law requirements, inspired by the principle of the “maximum safety technologically feasible”, but also pushed by the increased penetration of environmental issues into public opinion, and its meaning in terms of company image. Budgets for these improvements play a role in a general asset management strategy: de-dusting, being often an operation having low influence on production performances, is seen more as a “necessary cost” than a profit generator. The trend for companies, especially in the actual economical scenario, is to reuse existing de-dusting plants, enhancing their efficiencies rather than install new plants that would involve costs for the decommissioning of obsolete equipment. The obvious economic benefits of retrofits are counterbalanced by technical disadvantages. In particular, a systematic assessment of safety issues is required, not limited to the safety-oriented design of new machines, but extended in the evaluation of the impact that changes in process conditions (induced by the new equipment) can have on the existing ones.
In this work, explosion problems in the de-dusting section of a cement plant have been considered. Particularly, using fault tree analysis, it has been evaluated the changing in the overall risk (considering one year of mission time) of explosion referring to a hybrid-like collector realised by introducing a Fabric Filter (FF) downstream with respect to an Electrostatic Precipitator (ESP). Results have shown that a chain of failures in the FF section may affect relevantly the risk of explosions occurrence in the collector leading to the unavoidable need for the introduction of mitigation actions into the system
