Effect of Entrepreneurship Education on Students’ Entrepreneurial Intentions Educators' Perspectives at Universities in Norway and Russia

Master thesis Business Administration- University of Agder, 2015Øyvind Gustavsen (2013) explains that entrepreneurs, as creators of the employment places, are the most important drivers of economy development. Just in the period 2002-2007 in Norway, 248,000 new job places were developed in the companies younger than 5 years old, while 181,000 jobs disappeared at the companies older than 5 year. Therefore, when aiming to inspire entrepreneurship behavior (EB) and improvement of the quality of new start-ups and innovation, governments create programs, which strive to develop a cooperation between universities, schools, business and research institutions (Gustavsen, 2013 ). Bakotic and Kruzic (2010) state, that students are generators of the future economic development. Their entrepreneurial attitudes and behavior determine the future business activities and sustainability of economy (Bakotic & Kruzic, 2010). The Global Report (2014) of the Global Entrepreneurship Monitor (GEM) states that proactive approach in the developing of EB and enhancing entrepreneurial intentions requires consistent improving of entrepreneurship education (Singer, Amorós, & Arreola, 2015). The research literature within entrepreneurial intentions confirms that entrepreneurship education programs are the right and effective tool to enhance entrepreneurial intentions. However, researchers are inconsistent about their findings. One of the possible reasons to the inconsistency is the lack of any qualitative exploratory research papers within this particular topic. The other reason is the complexity of the “entrepreneurship” phenomenon. As a result, methodological biases and self-assessed questionnaires of students lead to the incomparable research findings. This master thesis deals with entrepreneurial intentions of students because of its potential effect on future context of entrepreneurship and economics impact. Educators’ perspective was chosen to view the entrepreneurship education – entrepreneurial intentions relationship from the other perspective based on instructors’ work and experience. It allowed finding variables which were neglected by the research based only on the students’ perspective. Two countries, Russia and Norway, research allowed to separate common for EE and dependent from the culture variables. The qualitative multiple case study design was chosen as a tool for the theory development study.

Genetic diversity of Tulipa suaveolens Roth populations in Volgograd Province

Background. The current natural habitat of Tulipa suaveolens Roth rapidly decreases. In order to work out the strategy of the species’ preservation, evaluation of its intraand interpopulation polymorphism is required.Materials and methods. Molecular-genetic ISSR markers were used to analyze 125 samples from 10 populations of T. suaveolens occurring in Volgograd Province and 4 populations from Saratov Province.Results. ISSR analysis revealed high intrapopulation polymorphism (73–89%) in T. suaveolens populations form Volgograd Province. AMOVA attributed the largest proportion of variability (74.3%) to intrapopulation polymorphism. Interpopulation differences account for 25.7%. Total subdivision of populations (FST) was 0.257; total gene flow (Nm) between populations was 0.723. According to Bayesian analysis and clustering with both UPGMA and Neighbor Joining methods, all the studied T. suaveolens samples from Volgograd Province make up a large genetic group: within that group none of the potential subgroups may be associated with a particular place of collecting. The NewHybrids software was applied, and the results pointed to the hybrid nature of most samples. Samples of three populations from Saratov Province made up a separate genetic group; those samples fell under the category of parent forms.Conclusion. Considering that genetic subdivision of T. suaveolens populations within the administrative borders of Volgograd Province is insignificant, while all the province’s natural parks and a number of protected natural areas undertake measures to preserve the species, the existing conservation strategy may be recognized as effective and sufficient

Стандарты обеспечения законности осуществления негласной деятельности в уголовном процессе: правовые позиции Европейского Суда по правам человека и компаративное исследование

The subject of research is the implementation of covert activities in criminal proceedings through the prism of international acts, decisions of the European Court of Human Rights.The purpose of the work is to formulate common standards for ensuring the legality of implementing covert activities in criminal process through the prism of legal positions of the European Court Of Human Rights.The methodological basis or research isthe totality of general and special scientific methods of scientific cognition. The formal-legal (legal-technical) method was used to study the rules of law, to analyze the features of legal technique; and the hermeneutical method revealed the legal content of the norms, legislative proposals and defects in legal regulation. The statistical method helped to generalize judicial practice of ECHR. While building up the system of the standards for the ensuring the legality of implementing covert activities in criminal process we used the system-structural method.The main results and conclusions. The analysis of the legal positions of the ECHR made it possible to conditionally single out the following standards for ensuring the legality of the implementation of covert activity in criminal proceedings:– predictability. Its essence lies in the fact that the grounds, procedural order, conditions, timing, the circle of persons and crimes in relation to which it is allowed to carry out covert activities should be as detailed, clear and accurate as possible in the criminal procedural legislation. Moreover, any person had the opportunity to familiarize himself with the relevant regulatory prescriptions and foresee the actions that can be carried out in relation to him;– warranty against abuse. The content of this standard can be disclosed by more detailed highlighting of clarifying provisions ("substandards"). These include: control of interference in human rights and freedoms; the certainty of the circle of persons in relation to whom it is possible to carry out secret activities; limited corpus delicti, for the purpose of investigation or prevention of which covert activity is allowed; the existence in national legislation of procedures that facilitate the law of the implementation of covert activity in criminal proceedings; the temporary nature of the implementation of secret activities in the criminal process;– verifiability. The essence of this standard can be disclosed through the establishment of judicial control over the decision of the issue regarding the possible destruction of information obtained in the course of conducting covert activities, which is not relevant to criminal proceedings, as well as the requirement for the mandatory opening of decisions that were the basis for conducting covert investigative actions;– exclusivity. The main content of this standard is that covert activity in criminal proceedings can be carried out only in cases where the disclosure or prevention of a crime in another way is impossible or is too complicated;– proportionality of the intervention and its expediency. The essence of this standard is that the implementation of certain covert coercive actions that are associated with the restriction of human rights and freedoms must be proportionate to the goals for which such actions are directed. Moreover, these goals and the applied coercion must be necessary in a democratic society;– inadmissibility of tacit interference in the communication of some subjects. First of all, this requirement concerns the need to legislatively guarantee non-interference in communication between a lawyer and his client, a priest and an accused, etc., which means a ban on targeted control over the communication of certain subjects, as well as the obligation to destroy information obtained in the course of an accidental, situational interfering with their communication.Анализируются правовые позиции Европейского Суда по правам человека, касающиеся процессуального порядка проведения негласных следственных действий в уголовном процессе. Выделяются стандарты обеспечения их законности. С целью всестороннего раскрытия данной проблематики также используется компаративный подход к исследованию, который способствовал выяснению особенностей воплощения выделенных стандартов в законодательстве некоторых стран

A subharmonic mixer for the 220–325 GHz frequency range

We have made a subharmonic mixer (SHM) for the 220–325 GHz frequency range with conversion losses lower than 30 dB at the intermediate frequency 3 GHz. The subharmonic mixer design was based on a GaAs mixer Schottky barrier diode with beam leads on a quartz 25-μm thick microwave board. The microwave board was placed in a package with a waveguide channel of local oscillator input (cross-sectional area 1.2×2.4 mm) and waveguide channel of signal input (cross-sectional area 0.4×0.8 mm² ). The IF signal goes out through a subminiature A-connector, wave impedance of which is 50 Ohm

Frequency dependence of magnetothermal properties for magnetic fluid and magnetically functionalized implants

Heating of the magnetic nanoparticles in AC magnetic field is the effect promising for application in medicine. The mechanisms of heating in AC-magnetic field implies nontrivial dependence of the power dissipated by magnetic nanoparticles on frequency. With the use of a reconfigurable experimental setup, this frequency-dependent magnetic heating was measured on two characteristic examples: the magnetite nanoparticles conventionally used in medicine and polymer coating with micrometer sized magnetite particles. The saturation of the heating power with frequency is shown that is more pronounced for the second case of microparticles

СТАТИСТИЧЕСКИЙ АНАЛИЗ ВЛИЯНИЯ Ge НА РАДИАЦИОННУЮ И ТЕРМИЧЕСКУЮ СТАБИЛЬНОСТЬ ЭЛЕКТРОФИЗИЧЕСКИХ ХАРАКТЕРИСТИК ПРИБОРНЫХ n—p—n—p–СТРУКТУР НА ОСНОВЕ CZ–Si

The characteristics of low−power and high−power thyristors basen of dislocation−free single crystal silicon doped with ger- manium to the concentration range NGe ~ (0.05—1.5) • 1020 cm−3 have been investigated. The criterial parameters of thyristors exposed to radiation and high temperature gradients have been estimated using experimental data processing methods in the STATISTICA and MathCAD environments. We show the appropriateness of using germanium doped silicon for increasing the thermal stability and radiation strength of the devices exposed to γ−radiation in the range of doses of up to 2.94 • 106 mSv.Исследованы характеристики мало- мощных и силовых тиристоров на основе бездислокационных монокристаллов кремния, легированных германием в диапазоне концентраций NGe ~ (0,05÷1,5) ⋅ 1020 см−3. С использованием методов обработки экспериментальных данных в среде STATISTICA и MathCAD оценены критериальные параметры тиристоров при действии облучения и высоких температурных градиентов. Показана целесообразность использования кремния, легированного германием, для повышения термической стабильности и радиационной стойкости приборов, подвергнутых действию γ−облучения в диапазоне доз до 2,94⋅ 106 мЗв.

The ecological and coenotic features of plant communities containing Colchicum bulbocodium subsp. versicolor (Colchicaceae) in the Lower Volga region

The article presents a phytocoenotic description of 23 plant communities with Colchicum bulbocodium subsp. versicolor studied during the period of mass fl owering in 2014–2018. It was found that, across the Lower Volga region, the studied communities with C. bulbocodium subsp. versicolor are mostly confi ned to the slopes of south- and east-facing arroyos and more seldom to the southern and northern hill slopes, plains, arroyo and liman bases, and fl oodmeadows. During the period of mass fl owering, 207 vascular plants were detected in the studied communities. Every community description included 9 to 36 species. Biological diversity was assessed with the Shannon index and polydominance index; the degree of dominance was measured with the Simpson index. The species similarity of the communities was evaluated through pairwise comparison with the Jaccard coeffi cient. It was revealed that C. bulbocodium subsp. versicolor occurs in communities varying in diversity and species composition. The subspecies is not confi ned to specifi c phytocoenoses. It usually grows on rich and, more seldom, fairly rich and slightly saline soils. Their alluviality is more often weak rather than moderate. Watering usually corresponds to the dry steppe or semi-desert climate type, rarely to the middle steppe type, being moderately variable and in some cases highly variable. The impact of grazing is usually weak, but it is either moderate or strong in some communities. The communities with C. bulbocodium subsp. versicolor are dominated by hemicryptophytes: mostly tap-root, short-rhizome and long-rhizome herbaceous perennials. In phytocoenotic terms, most species belong to the zonal type of vegetation, namely steppe vegetation. The participation of meadow species is prominent. The share of weed species is rather high, which indicates a signifi cant anthropogenic load on the studied communities
