Simpler multicoloring of triangle-free hexagonal graphs
Petra Šparl, Janez Žerovnik, Ignasi Sau Walls, 2012, objavljeni znanstveni prispevek na konferenci

Opis: Preslikavo ▫$f colon V(G)to 2^{{1,.,n}}$▫, za katero velja ▫$|f(v)| ge p(v)$▫ za vsako točko ▫$v in V(G)$▫ in ▫$f(v) cap f(u) = emptyset$▫ za poljubni sosedi ▫$u$▫ in ▫$v$▫ grafa ▫$G$▫, imenujemo dobro ▫$n-[p]$▫barvanje grafa ▫$G$▫. Najmanjše naravno število, za katero obstaja dobro ▫$n-[p]$▫barvanje grafa ▫$G$▫, ▫$chi_p(G)$▫, imenujemo uteženo kromatično število grafa ▫$G$▫. Iskanje uteženega kromatičnega števila za inducirane podgrafe trikotniške mreže (imenovane heksagonalni grafi) ima aplikacije v celičnih mrežah. Uteženo kromatično število grafa ▫$G$▫, ▫$omega_p(G)$▫, je enako maksimalni uteži klike grafa ▫$G$▫, kjer utež klike predstavlja vsoto uteži njenih točk. McDiarmid in Reed (2000) sta postavila domnevo, da za poljuben heksagonalen graf brez trikotnikov velja ▫$chi_p(G) le (9/8)omega_p(G) + C$▫. V članku je podan algoritem, ki poda dobro ▫$7-[3]$▫barvanje poljubnega heksagonalnega grafa brez trikotnikov, ki aplicira neenakost ▫$chi_p(G) le (7/6)omega_p(G) + C$▫. Naš rezultat podaja krajšo alternativo induktivnega dokaza Haveta (2001) in izboljša kratek dokaz Sudepa in Vishwanathana (2005), ki sta dokazala obstoj ▫$14-[6]$▫barvanja. (Omeniti je potrebno, da v sklopu našega dokaza uporabimo izrek o štirih barvah.) Vsi koraki algoritma so linearni glede na ▫$|V(G)|$▫, razen 4-barvanje ravninskega grafa. Novi pristop lahko v prihodnje pripomore k dokazovanju domneve McDiarmida in Reeda (2000).

Impact of fixed choice design on blockmodeling outcomes
Anja Žnidaršič, 2012, izvirni znanstveni članek

Opis: The main goal of blockmodeling is to reveal the essential structure of the network based on patterns of relationships. Social network data usually contain different types of errors and one of them is caused by some limitation of number of selected actors in the research design. The impact of fixed choice design compared to free choice design on the results of blockmodeling are studied through simulations. The resulting blockmodels are compared with two indices where position membership of actors and the structure of the blockmodels are examined. Limiting the number of actors that can be selected has an impact on delineated blockmodel structure where the deletion of ties has higher effect than addition of them.

Absent ties in social networks, their treatments, and blockmodeling outcomes
Anja Žnidaršič, Anuška Ferligoj, Patrick Doreian, 2012, izvirni znanstveni članek

Opis: An absent tie is one for which we have no information regarding its nature. Absent ties for a network is a set of such ties. This lack of information can be present anywhere in network data and has the potential to compromise the results of all network analytic tools. To assess this impact, we used real networks and based simulations on them by introducing varying amounts of absent ties. They were treated with four treatments of absent ties. Blockmodeling, using structural equivalence, was applied to the known networks and then to every treated network. The results were compared. The amount of absent ties, their treatments, the block structure of a network, and the level of reciprocity all have an effect of the adequacy of the results of blockmodeling. Reconstruction combined with imputation based on modal values was the best overall treatment. However, treatments of absent ties can work for some networks but not others and we recommend treatments of absent ties based on the form of networks.

Telework in Slovenia
Miro Gradišar, Eva Jereb, 1998, znanstvena monografija

Opis: Čeprav je raziskav teledela veliko, pa je večina omejenih le na ZDA in države Evropske skupnosti. V državah centralne in vzhodne Evrope pa do zdaj še ni bilo tovrstnih raziskav. V prispevku so prikazani rezultati raziskave teledela v Sloveniji, ki je bila izvedena v letu 1997. Podana je tudi primerjava stanja v Sloveniji s stanjem v nekaterih drugih evropskih državah.

Cost-effective restructuring based on process approach
Ivan Todorović, Stefan Komazec, Miha Marič, Jovan Krivokapić, 2013, izvirni znanstveni članek

Opis: Different authors agree that designing the organizational structure in accordance with the business processes can bring numerous advantages, which improve business performance of the organizational system. This article aims to show how cost-effective restructuring, through modification of organizational structure according to business processes that exist in the organization, can bring numerous benefits. Successful implementation of process organizational model does not necessarily demand large investments, but only adequate structural changes and internal reorganization. The data used in this paper were gathered during the project of restructuring one transportation company from Belgrade, which consulting team from Faculty of Organizational Sciences, University of Belgrade, performed in year 2012.

Human resource development in a small company
Dušanka Kermc, Mojca Bernik, 2013, izvirni znanstveni članek

Opis: The small business sector is often overlooked in human resource development researches, despite representing a large portion of the total economy. Very few studies exist on the subject of human resources development needs analysis in small organisations. Development plans remain mostly unwritten, which can lead to the impression that development is not being implemented or planned and is therefore not valid. This paper presents case study of the existing human resource development system in a small company PAN -JAN d.o.o. The research included 80% of all employees, which is 20 out of 25. The research examined the correlation between the additional education and better business performance, analysis of variance on age and number of courses and discriminant analysis on age, years of service, levels of education and legally required education and training programmes. In discussion are proposed changes or improvements, as well as a human resource development model.
