Aggregation of media content comes as a popular form of media market activity which is supposed to facilitate access to information in the conditions of its excessive amount. It can be defined as selection and hierarchization of information and determination of its value. Aggregation can be performed with the direct participation of editorial teams, or it can be performed automatically, with the use of algorithms. The research conducted in April 2014 – April 2015 was to indicate the sources of information published by the news portals dominating on the Polish market, namely: Onet.pl and WP. pl. The research referred to the main section Wiadomosci (News). During the research 1829 sources of information were identified in Onet.pl and 2272 sources of information in WP.pl. Considering Onet.pl, there were 549 pieces of the portal news and 1239 pieces of news obtained from different sources. WP.pl presented 582 pieces of the portal news and 1690 pieces of news received from other sources. Thus, Onet.pl presented its original content more frequently. The scale of using external sources allows us to state that both portals are, first of all, the aggregators of medial contents, and they use external information sources, however the scale of the practice is differentiated. Generally, it is possible to state that only every third message placed in the most important section of both portals was created in their editorial offices.

AbstractA new methodology for estimating the depolarization ratio (DR) by dual-polarization radars with simultaneous transmission/reception of orthogonally polarized waves together with traditionally measured differential reflectivity ZDR, correlation coefficient ρhυ, and differential phase ΦDP in a single mode of operation is suggested. This depolarization ratio can serve as a proxy for circular depolarization ratio measured by radars with circular polarization. The suggested methodology implies the use of a high-power phase shifter to control the system differential phase on transmission and a special signal processing to eliminate the detrimental impact of differential phase on the estimate of DR. The feasibility of the suggested approach has been demonstrated by retrieving DR from the standard polarimetric variables and the raw in-phase I and quadrature Q components of radar signals and by implementing the scheme on a C-band radar with simultaneous transmission/reception of horizontally and vertically polarized waves. Possible practical implications of using DR include the detection of hail and the determination of its size above the melting layer, the discrimination between various habits of ice aloft, and the possible identification and quantification of riming, which is associated with the presence of supercooled cloud water. Some examples of these applications are presented.

AbstractThis article provides a framework for systematically analyzing the practice, function, and consequences of human rights references in investment arbitration. In recent years, investment arbitration witnessed an enormous increase of references to external sources. References to human rights are especially interesting as they defy the alleged inherent conflict of investment and human rights, as well as the presumed fragmentation of international law. By applying both quantitative and qualitative approaches, I analyze how and why human rights references are employed in investor-state arbitration and, ultimately, whether they are able to remedy the legitimacy crisis of investment arbitration.The empirical analysis is based on 46 awards, which include explicit references to human rights instruments. In the first part, this article examines which human rights instruments are referenced in investment arbitration and how the disputing parties as well as the tribunal engage in human rights referencing. In the second step, the article identifies two strategic functions of referencing human rights: guidance in the determination of substantive provisions and argumentative practice. This article further argues that, from a comparative law perspective, references may help to overcome the indetermination of investment treaties, provide for the balancing of investment and non-investment concerns, and ensure cross-regime consistency. In the third step, this article elaborates on whether those presumed benefits of referencing human rights can be confirmed on the basis of empirical results. It remains to be seen whether the ‘pick and choose’ approach of human rights references is capable of uncovering this legitimating potential.
