Comparison of Contemporary Protocols for High-speed Data Transport via 10 Gbps WAN Connections

This work is dedicated to comparison of open source as well as proprietary transport protocols for highspeed data transmission via IP networks. The contemporary common TCP needs significant improvement since it was developed as general-purpose transport protocol and firstly introduced four decades ago. In nowadays networks, TCP fits not all communication needs that society has. Caused of it another transport protocols have been developed and successfully used for e.g. Big Data movement. In scope of this research the following protocols have been investigated for its efficiency on 10Gbps links: UDT, RBUDP, MTP and RWTP. The protocols were tested under different impairments such as Round Trip Time up to 400 ms and packet losses up to 2%. Investigated parameters are the data rate under different conditions of the network, the CPU load by sender andreceiver during the experiments, size of feedback data, CPU usage per Gbps and the amount of feedback data per GiByte of effectively transmitted data. The best performance and fair resources consumption was observed by RWTP. From the opensource projects, the best behavior is showed by RBUDP.

Spatial relational learning and memory abilities do not differ between men and women in a real-world, open-field environment

This study assesses gender differences in spatial and non-spatial relational learning and memory in adult humans behaving freely in a real-world, open-field environment. In Experiment 1, we tested the use of proximal landmarks as conditional cues allowing subjects to predict the location of rewards hidden in one of two sets of three distinct locations. Subjects were tested in two different conditions: (1) when local visual cues marked the potentially-rewarded locations, and (2) when no local visual cues marked the potentially-rewarded locations. We found that only 17 of 20 adults (8 males, 9 females) used the proximal landmarks to predict the locations of the rewards. Although females exhibited higher exploratory behavior at the beginning of testing, males and females discriminated the potentially-rewarded locations similarly when local visual cues were present. Interestingly, when the spatial and local information conflicted in predicting the reward locations, males considered both spatial and local information, whereas females ignored the spatial information. However, in the absence of local visual cues females discriminated the potentially-rewarded locations as well as males. In Experiment 2, subjects (9 males, 9 females) were tested with three asymmetrically-arranged rewarded locations, which were marked by local cues on alternate trials. Again, females discriminated the rewarded locations as well as males in the presence or absence of local cues. In sum, although particular aspects of task performance might differ between genders, we found no evidence that women have poorer allocentric spatial relational learning and memory abilities than men in a real-world, open-field environment.

Application of Open Innovation Paradigm in Small and Medium Enterprises in Russia

The objective of this study is to explore how the Open Innovation paradigm is applied in by small and medium-size enterprises in Russia. The focus of the study is to understand how the processes of research and development and commercialization proceed in these kind of companies and to which extent they apply open innovation principles. Russian leadership makes certain steps for transition from the export of raw materials to an innovative model of economic growth. The research aims to disclose actual impact of these attempts. The closed innovation model and the erosion factors which lead to the destruction of an old one and emergence of new model are described. Features of open innovation implementation and intellectual property rights protection in small and medium enterprises are presented. To achieve the objective, a qualitative case study approach was chosen. Research includes facts and figures, views and opinions of management of studied companies related to innovation process in the company and in Russia in general. The research depicts the features of Open Innovation implementation by SMEs in Russia. A large number of research centers with necessary equipment and qualified personnel allow case companies to use external R&D effectively. They cooperate actively with research institutes, universities and laboratories. Thus, they apply inbound Open Innovation. On the contrary, lack of venture capital, low demand for technologies within the domestic market and weak protection of intellectual property limit the external paths to new markets. Licensing-out and creation of spin-off are isolated cases. Therefore, outbound Open Innovation is not a regular practice.

Applying andragogy to the open college learner

Questionnaires were sent to 703 Open College students. The questionnaire asked questions regarding personal demographics, how they felt about andragogy as postulated by Malcolm Knowles, and invited responses pertaining to the institutional practices of Open College. Two hundred and ninety-four responses were received. The information was synthesized and used descriptively. The information regarding andragogy was also used descriptively and analyzed using chi-square. The statistics were compared by gender. No significant difference was found. Students rejected the concept of self-directed learning. They did use their past experience when preparing assignments, however. They also entered Open College in order to learn how to do something better rather than for esoteric reasons. In fact, their whole orientation to learning was very practical in nature. The factors motivating these learners were internal rather than external. In addition, institutional practices were identified that could further enhance the Open College experience.

International volunteers at a Costa Rican organic farm : sheepish volunteers, proud tourists and unwitting developers

This thesis analyzes the practices and experiences of two groups of Canadian volunteers who visited the organic fanning and "alternative development" project ofFinca la Flor (FLF) in central Costa Rica. Using both participant observation and in-depth interviews with volunteers and other people involved with FLF, I examine volunteers' understandings of their involvement with the fann. I argue that three discursive fonnations are instrumental in shaping this particular volunteering encounter. Specifically, interpretation of these Canadian volunteers' experiences inspires the argument that the emerging practice of international volunteering (or voluntourism) exists at the intersection of discourses of development, volunteering and tourism, all of which both reflect and maintain problematic North-South relationships. The analysis shows that in spite ofFLF's construction as an (alternative / sustainable) international-development project, and in spite of volunteers' initial conceptualization of their trip as "volunteering," volunteers tend to act and describe their time at FLF in ways that look more like tourism than like volunteer labor or international development. Likewise, although FLF claims to principally be focused on alternative development, and merely to open up this authentic development space to volunteers for their participation, the organization in both practice and discourse seems primarily to construct a tourist experience and cater to the needs of foreigners as tourists. Discourses of development and volunteering do infonn the practices offann personnel and volunteers at FLF, but they become subordinated to the more dominant discourse of tourism as the volunteers' and fann management's ideals of development and volunteering capitulate to become focused on satisfying volunteers' (perceived or "real") touristic desires. The FLF participants I studied may have entered the encounter as volunteers, but they departed the site having been tourists.

Finding the Open Spaces in Closed Systems: An Exploration of Critical Pedagogy with a Social Justice Directive in an Ontario Secondary School Classroom

This study examines the first experience of students, teachers, and an administrator in implementing a teacher-designed Leadership in Social Justice Program at a large urban Ontario secondary school. The program aimed to infuse a Freirean concept of critical pedagogical praxis (Freire, 1970/1993) in a grade 12 integrated educational experience with a social justice directive. Data were collected through two questionnaires and eight in-depth interviews. The data identified three areas of awareness that described ways in which student participants were impacted most profoundly (a) developing self-awareness, (b) understanding a new educational paradigm, and (c) finding a place in the world. The study found that the program was successful in highlighting the possibility for more meaningful education and engaged many students deeply; however, its success was limited by the lead teacher’s failure to fully grasp and implement tenets of Freirean critical pedagogy that involved the role of the teacher in pedagogical processes.
