The International Human Rights Policies of New Democracies: Brazil and Chile in Comparative Perspective

Since the beginning of the 1990s, the majority of Latin American states have attempted to incorporate in some way or another human rights concern into their respective foreign policies, highlighting a history of human rights abuses and the return of democratic political rule as a trigger for galvanizing a commitment to assist in preventing such violations in other countries. Yet, while human rights have come to play a non-trivial role in the contemporary foreign policy of many Latin American states, there is great diversity in the ways and the extent to which they go about incorporating human rights concerns into their foreign policies. Explaining the diversity of human rights foreign policies of new Latin American democracies is at the heat of this project. The main research questions are the following: Why do new democracies incorporate human rights into their foreign policies? And what explains the different international human rights policies of new democracies? To answer these questions, this research compares the human rights foreign policies of Chile and Brazil for over two decades starting from their respective transitions to democracy. The study argues that states commitment to international human rights is the result of the intersection of domestic and international influences. At the international level, the search for international legitimacy and the desire for recognition and credibility affected the adoption of international human rights in both cases but with different degrees of impact. International values and pressures by themselves, while necessary, are an insufficient condition for human rights initiatives perceived to have not insubstantial political, economic or strategic costs. New democracies will be more or less likely to actively include human rights in their international policies depending on the following four domestic conditions: political leadership legitimizing the inclusion of human rights into a state's policies, civil society groups connected to international human rights advocacy networks with a capacity to influencing the foreign policy decisions of their government, and the Foreign Ministry's attitudes towards international human rights and the degree of influence it exercises over the outcome of the foreign policy process.

Human Motion Analysis Based on Sequential Modeling of Radar Signal and Stereo Image Features

Falls are one of the greatest threats to elderly health in their daily living routines and activities. Therefore, it is very important to detect falls of an elderly in a timely and accurate manner, so that immediate response and proper care can be provided, by sending fall alarms to caregivers. Radar is an effective non-intrusive sensing modality which is well suited for this purpose, which can detect human motions in all types of environments, penetrate walls and fabrics, preserve privacy, and is insensitive to lighting conditions. Micro-Doppler features are utilized in radar signal corresponding to human body motions and gait to detect falls using a narrowband pulse-Doppler radar. Human motions cause time-varying Doppler signatures, which are analyzed using time-frequency representations and matching pursuit decomposition (MPD) for feature extraction and fall detection. The extracted features include MPD features and the principal components of the time-frequency signal representations. To analyze the sequential characteristics of typical falls, the extracted features are used for training and testing hidden Markov models (HMM) in different falling scenarios. Experimental results demonstrate that the proposed algorithm and method achieve fast and accurate fall detections. The risk of falls increases sharply when the elderly or patients try to exit beds. Thus, if a bed exit can be detected at an early stage of this motion, the related injuries can be prevented with a high probability. To detect bed exit for fall prevention, the trajectory of head movements is used for recognize such human motion. A head detector is trained using the histogram of oriented gradient (HOG) features of the head and shoulder areas from recorded bed exit images. A data association algorithm is applied on the head detection results to eliminate head detection false alarms. Then the three dimensional (3D) head trajectories are constructed by matching scale-invariant feature transform (SIFT) keypoints in the detected head areas from both the left and right stereo images. The extracted 3D head trajectories are used for training and testing an HMM based classifier for recognizing bed exit activities. The results of the classifier are presented and discussed in the thesis, which demonstrates the effectiveness of the proposed stereo vision based bed exit detection approach.

Human Rights in the Democratic People's Republic of Korea and the Future of the Troubled State after Kim Jong-Il

Since 2008, international speculation about the viability of Kim Jong-Il's leadership in North Korea has been at the forefront of diplomatic discussions. North Korea is known to be a secretive state where human rights violations abound. This paper discusses the history of leadership and government in North Korea since World War II, the current human rights situation in the country, the role of China, and potential successors to Kim Jong-Il. The ramifications of impending regime change are discussed in terms of North Korea's human rights issues and economic problems. While current efforts at diplomacy have proved ineffective, the need for concerned nations, intergovernmental organizations, and non-governmental organizations to be prepared to engage North Korea after Kim Jong-Il is imperative.
