马克思主义人权观的基本特征

马克思主义人权观是马克思主义理论的重要组成部分.马克思主义人权观的基本特征表现在四个方面:人权来源问题上的科学性、人权属性问题上的真实性、人权内容问题上的整体性、人权发展问题上的实践性.     

结合人体运动特征的行为识别

人体运动具有马尔可夫性质,即当前状态只受前一状态的影响.目前为止,用于人体行为识别的隐马尔可夫模型（HMM）大多使用的是全连接结构（Full-Connected structure）,并且没有把状态数目的选取和状态转移条件与人体运动特性间的关系作为研究重点.本文针对这种关系提出了基于“从左到右三状态半连接HMM”的人体行为识别方法,为每个状态的输出概率引入了权重的概念.实验表明,该方法能够在降低运算复杂度的同时,提高行为识别率,从而证明了人体运动特性分析在HAR领域中的应用价值.

Towards safety improvement: implementation and assessment of new standards of competence for Electro-Technical Officers on ships

The paper deals with education of ship engineers as an integral part of maritime policy in global shipping. The central problem, how to reconcile technological advancement with training en route to improving safety, is defined. A complete conceptual model for solving a central question is formulated and described. At the beginning, a short analysis of technological advances and the need for training is presented. Next, the basic components of conceptual model, including implementation and assessment of new standards of competences for Electro-Technical Officers in the wake of Maritime Education and Training (MET) development are discussed. A key point of the assessment procedure is focused on the formulation of criterion defining the impact of new standards on the given processes characterizing a professional carrier development of seafarers. These processes, which mean certification process and recruitment of candidates to seafarer profession, are strongly linked with and influenced on MET development and improving the safety of shipping. Empirical application by pointing the Polish case study to the framework of conceptual model under consideration is shown and analysed. Finally, the future works as well as the concluding remarks are formulated and commented on.     

Transportation mode detection – an in-depth review of applicability and reliability

The wide adoption of location-enabled devices, together with the acceptance of services that leverage (personal) data as payment, allows scientists to push through some of the previous barriers imposed by data insufficiency, ethics and privacy skepticism. The research problems whose study require hard-to-obtain data (e.g. transportation mode detection, service contextualisation, etc.) have now become more accessible to scientists because of the availability of data collecting outlets. One such problem is the detection of a user's transportation mode. Different fields have approached the problem of transportation mode detection with different aims: Location-Based Services (LBS) is a field that focuses on understanding the transportation mode in real-time, Transportation Science is a field that focuses on measuring the daily travel patterns of individuals or groups of individuals, and Human Geography is a field that focuses on enriching a trajectory by adding domain-specific semantics. While different fields providing solutions to the same problem could be viewed as a positive outcome, it is difficult to compare these solutions because the reported performance indicators depend on the type of approach and its aim (e.g. the real-time availability of LBS requires the performance to be computed on each classified location). The contributions of this paper are three fold. First, the paper reviews the critical aspects desired by each research field when providing solutions to the transportation mode detection problem. Second, it proposes three dimensions that separate three branches of science based on their main interest. Finally, it identifies important gaps in research and future directions, that is, proposing: widely accepted error measures meaningful for all disciplines, methods robust to new data sets and a benchmark data set for performance validation.
