Productivity and economic growth in the European Union
Andreja Nekrep, Sebastjan Strašek, Darja Boršič, 2018, izvirni znanstveni članek

Opis: This paper focuses on investment in research and development as a factor of labour productivity and economic growth. Our analysis confirms the link between expenditure for research and development (expressed in % of GDP) and labour productivity (expressed in the number of hours worked) based on selected data for EU Member States in the period 1995-2013. A causal link between variables of the concave parabola was confirmed, and the value of expenditure for research and development (2.85% of EU GDP) maximising productivity (per hour of work) was determined based on the examined data. In accordance with these findings, EU’s target of reaching 3% of GDP spent on research and development to be achieved by 2020 seems in support of reaching maximum productivity in the EU.

Use of ergonomic principles in manual order picking systems
Nina Labus, Brigita Gajšek, 2018, izvirni znanstveni članek

Opis: Successful companies are continually striving to streamline costs and optimize processes, enabling them to grow progress, develop and ensure competitiveness on the market. A large part of the costs arises in warehouses, where up to 55% of total costs are generated by order- picking, which makes it important and interesting in terms of research. The paper explores "picker to part" order- picking concept, which enables flexible work and is the optimal choice for most companies. The concept is associated with a high level of work- related injuries and work -related illnesses. Work requires physical efforts resulting from handling heavy goods, performing repetitive movements and using manipulative means. Hum an as the main actor of the concept affects the costs caused by picking and the quality of work done, which depends on technological support, physically and psychologically capable and motivated people. Due to the high costs of service, the focus on time planning and productivity increases. Contrary, the lack of attention is paid to the working conditions and the health status of the pickers. To overcome this gab, a review of scientific and professional literature on ergonomic principles in picking concept "picker to part" was carried out, followed by a quantitative survey of ergonomic properties in warehousing activities. Results revealed that more than 60% of the surveyed order-pickers associate problems with health with the characteristics of work, about 24% of them associate health problems with the use of a particular means of transport, and all agree that provided measures to reduce physical effort and greater support of technologies influence on increased speed of work and better health status of order-pickers.

Information technology and organizational effectiveness
Markku Sääksjärvi, 2010, izvirni znanstveni članek

Opis: The idea of this paper is to review and summarize the complex interplay between information technology (IT) and organization in stages that impacted radically both the organizational structure and the evolution of effectiveness and economic performance. We could identify five major stages where the underlying technology, the typical organizational structure, and the criteria of performance or business success changed, increasing the complexity of evaluation models proposed. It seemed that the effectiveness impacts of IT escalated from the individual to the team level, from the organizational to the virtual ecosystem level, and from the corporate to the national or global level. Therefore, the IT productivity paradox could not be refuted until 2003.

Analyzing the process of patent aubmission with a special emphasis on the phases of the research process
Mitja Ruzzier, Tine Nagy, Robert Ravnihar, 2009, izvirni znanstveni članek

Opis: This article presents some findings about the process of patenting of Slovenian and foreign researchers in scientific research. Based on the reviewed literature and with help of our conceptual model, we establish that the patenting process can be divided into three separate phases: knowledge detection phase, knowledge dissemination phase and knowledge transfer phase. During the process of researching and patenting, a variety of factors affect the results, which can be divided into two groups: internal and external factors. In Slovenia, patents are statistically significant for researchers working and exploring in the fields of natural science and engineering. Research results in the form of a patent largely depend on financial support and work experiences of individual researchers or research groups. The commercialization of a patent means a successful ending of the research process, as many positive benefits are expected.

Seaport efficiency and productivity based on Data Envelopment Analysis and Malmquist Productivity Index
Joanna Baran, Aleksandra Górecka, 2015, izvirni znanstveni članek

Opis: Seaport efficiency and productivity are the critical factors for handling of goods in the international supply chains and plays an important role in trade exchange with other countries. It is important to evaluate efficiency and productivity of seaports to reflect their status and reveal their position in competitive environment. The main purpose of this article is to use Data Envelopment Analysis and Malmquist Productivity Index to measure the technical efficiency and total factor productivity of container ports. DEA analysis enables one to assess how efficiently a seaports uses the available inputs to generate a set of outputs relative to other units in the data set. This article presents the use CCR and BCC DEA model, to determine overall technical efficiency, pure technical efficiency and scale efficiency of container ports. The analysis gives a possibility to create a efficiency ranking of seaports. The study also applies the Malmquist Productivity Index (MPI), which was used to analyze changes in seaports productivity. The study indicated that technological progress had a greater impact on the change in productivity of container ports than changes in technical efficiency.

Growth performance, productivity and diseases susceptibility of barley varieties in Slovenia within the Cobra project's site comparison
Silva Grobelnik Mlakar, Manfred Jakop, Martina Robačer, Martina Bavec, Franc Bavec, 2016, izvirni znanstveni članek

Opis: Different plant genotypes react differently in different climates. A field experiment was carried out to estimate the growth performance, productivity and diseases susceptibility of spring barley varieties in the Slovenian climate. We received some varieties, mainly of Nordic origin, from the Technical University of Denmark, a COBRA project partner, which were previously tested in estimated future climate in RERAF phytotron. Varieties of the highest grain yield (3,993 kg ha$^{-1}$ in ‘Evergreen’ to 5,146 kg ha$^{-1}$ in ‘Sebastian’) were rather shorter (58.7 cm to 67.1 cm) and mostly had the highest specific grain weight (54.3 to 58.6 kg 100 L$^{-1}$) and 1000-kernel weight (30.2 to 37.1 g). They developed 1,561 to 2,532 tillers m$^{-2}$ and 515 to 840 ears m$^{-2}$ and reached a heading stage between 13th and 25th of May. The tested varieties seem rather insusceptible to most common diseases, but susceptible to cereal leaf beetle attacks.

Experimental investigation of the quality and productivity of software factories based development
Andrej Krajnc, Marjan Heričko, Črt Gerlec, Uroš Goljat, Gregor Polančič, 2012, izvirni znanstveni članek

Opis: Software organizations are always looking for approaches that help improve the quality and productivity of developed software products. Quality software is easy to maintain and reduces the cost of software development. The Software Factories (SF) approach is one of the approaches to provide such benefits. In this paper, the quality and productivity benefits of the SF approach were examined and evaluated with an experiment involving two treatments - the traditional and the SF approach. For the purposes of this experiment, the Goal – Question – Metric (GQM) approach was used. Participants were grouped into thirty two teams. There were sixteen projects available. The results were evaluated and presented through quality and productivity criteria, which were used for the experimental study. The results showed that the Software Factories approach was significantly better than the traditional approach.
