    This study investigated Romania's early 1960s policy change towards the Soviet Union, focusing on two questions why the change occurred and what actually changed. Calling it detachment from Moscow, dissidence, new state security strategy, independent or autonomous line, historiography focuses from an objectivist perspective on the external permissive conditions that allowed the change. It works within a paradigm which maintains that after the war Romania allied (balanced) with the USSR against the Western threat but contends that Romania s alliance with the USSR and its (post-1960) opposition to the USSR were mutually exclusive. In tackling this dichotomy, some scholars argue that the change was simulated or apparent, while others acknowledge a partial, incomplete detachment but pay little attention to what actually changed. Drawing from recently declassified archive materials, this study used a perceptual approach and a paradigm which argues that post-war Romania allied not against the threat but with the (perceived) threat the USSR. It focused on the proximate causes triggering the change and explained what changed. It investigated the emergence of Romania s opposition to the USSR mainly through two case studies (the CMEA reform process and the Sino-Soviet dispute) and covered the period between 1960 and 1964 between Romania s first categorical (albeit non-public and indirect) opposition to the USSR and the issuing of the Declaration marking Romania s first public and official (although indirect) acknowledgement of the disagreements with the USSR. This study found that the proximate causes of Romania s policy change towards the Soviet Union resided in the Romanian leaders perceptions of the threats posed to Romania s interests by various specific Soviet policies, such as the attempts to impose the CMEA integration or a strong collective riposte against China. The Romanian leaders considered that such Soviet policies had to be blocked, but they feared that opposition risked triggering even bigger threats or even the ultimate (perceived) threat to Romania s security an open confrontation with the USSR. Thus, they responded to the perceived threats by conceptualising the change in Romania s policy towards the USSR not in terms of breaking off the alliance, but in terms of finding practical ways (tactics) to block specific (perceived) less-than-ultimate Soviet threats, without provoking a confrontation with the USSR. Through its findings, this study opens new research perspectives on the Romanian-Soviet post-war relations and on the role of the leaders beliefs in Romania s foreign policy choices. It may also be a starting point to understand the unusual present-day relations between Romania and the Russian Federation.

    Howick et al. have reported the findings of a survey that addressed the use of placebos among primary care practitioners in the United Kingdom. They adopted methodology similar to that used in previous studies performed in other countries; however, the use of this approach also means that they repeated the conceptual confusion of the previous surveys. Therefore the findings are not useful. ... The paper’s main finding “placebos are commonly used in UK primary care” is not correct. Only 0.9% of the responding general practitioners reported using pure placebos frequently. The frequency with which impure placebos are used is irrelevant because the concept is useless, as described above. Misleading a patient by administering inert substances without the explicit consent of the patient is unethical. The authors' proposal to “develop ethical and cost-effective placebos” is not possible because saving money by misleading patients is unethical. There is substantial conceptual confusion in the area of placebo and placebo-effect research, and the paper by Howick et al. does not help to reduce this confusion.

    In this paper we will present results from field measurements at the River Kymijoki gathered during winter 2011/2012. River Kymijoki research project was started in fall 2011 and these results are part of the results that were made for master’s thesis of Tom Kokkonen. River Kymijoki is located in southeast Finland, it freezes annually, and the catchment area of the river is 37 107 km2 which is about 11 % of the area of Finland. The lake percentage of the river catchment is 19 %. Aim of this first stage of the research project was to select measurement points and evaluate their suitability to present the River Kymijoki ice and water quality phenomena. Other goal for the project was to examine the collected data and process a comprehensive image of the River Kymijoki ice phenomena and water quality.

    Cloud-based infrastructure has been increasingly adopted by the industry in distributed software development (DSD) environments. Its proponents claim that its several benefits include reduced cost, increased speed and greater productivity in software development. Empirical evaluations, however, are in the nascent stage of examining both the benefits and the risks of cloud-based in-frastructure. The objective of this paper is to identify potential benefits and risks of using cloud in a DSD project conducted by teams based in Helsinki and Ma-drid. A cross-case qualitative analysis is performed based on focus groups con-ducted at the Helsinki and Madrid sites. Participants’ observations are used to supplement the analysis. The results of the analysis indicated that the main ben-efits of using cloud are rapid development, continuous integration, cost savings, code sharing, and faster ramp-up. The key risks determined by the project are dependencies, unavailability of access to the cloud, code commitment and inte-gration, technical debt, and additional support costs. The results revealed that if such environments are not planned and set up carefully, the benefits of using cloud in DSD projects might be overshadowed by the risks associated with it.

    We present a distributed 2-approximation algorithm for the minimum vertex cover problem. The algorithm is deterministic, and it runs in (Δ + 1)2 synchronous communication rounds, where Δ is the maximum degree of the graph. For Δ = 3, we give a 2-approximation algorithm also for the weighted version of the problem.
  • CowLog 
    Hänninen, Laura; Pastell, Matti (2009)
    We have developed CowLog, which is open-source software for recording behaviors from digital video and is easy to use and modify. CowLog tracks the time code from digital video files. The program is suitable for coding any digital video, but the authors have used it in animal research. The program has two main windows: a coding window, which is a graphical user interface used for choosing video files and defining output files that also has buttons for scoring behaviors, and a video window, which displays the video used for coding. The windows can be used in separate displays. The user types the key codes for the predefined behavioral categories, and CowLog transcribes their timing from the video time code to a data file. CowLog comes with an additional feature, an R package called Animal, for elementary analyses of the data files. With the analysis package, the user can calculate the frequencies, bout durations, and total durations of the coded behaviors and produce summary plots from the data.
