The available statistical data are analyzed to appraise the success of Canada's Pacific salmon fleet rationalization program, in terms of the extent to which it has prevented fishing costs from rising in pace with the value of the catch. It is found that while the fleet's revenues increased at about the same rate before and after the scheme was introduced in 1969, the real capital employed increased more slowly under the controls than earlier. The program has, nevertheless, failed in its purpose of preventing further expansion of redundant capital in the fleet. The reasons for this failure, and for certain apparent shifts in the structure of the fleet, are discussed. Key words: Pacific salmon fishery, capitalization, economic rationalization, resource rent

Aims: To evaluate the real-life effect of photocatalytic surfaces on the air quality at two test-sites in Denmark. Background: Poor air quality is today one of the largest environmental issues, due to the adverse effects on human health associated with high levels of air pollution, including respiratory issues, cardiovascular disease (CVD), and lung cancer. NOx removal by TiO2 based photocatalysis is a tool to improve air quality locally in areas where people are exposed. Methods: Two test sites were constructed in Roskilde and Copenhage airport. In Roskilde, the existing asphalt at two parking lots was treated with TiO2 containing liquid and an in-situ ISO 22197-1 test setup was developed to enable in-situ evaluation of the activity of the asphalt. In CPH airport, photocatalytic concrete tiles were installed at the "kiss and fly" parking lot, and NOx levels were continuously monitored in 0.5 m by CLD at the active site and a comparable reference site before and after installation for a period of 2 years. Results: The Roskilde showed high stability of the photocatalytic coating with the activity being largely unchanged over a period of 2 years. The CPH airport study showed that the average NOx levels were decreased by 12 % comparing the before and after NOx concentrations at the active and reference site. Conclusion: The joined results of the two Danish demonstration projects illustrate a high stability of the photocatalytic coating as well as a high potential for improvements of the real-life air quality in polluted areas.

Contact width is important design parameter for optimizing design of new metal gasket. The contact width was found have relationship with helium leak quantity. Increasing axial force, the contact width will increase and helium leakage will decrease. This study we conducted the surface roughness evaluation of 25A-size metal gasket before and after use. The results denote the real contact width after contact with flange having different surface roughness. The real contact width for the flange having smoother surface roughness is wider than the rougher one.

- This study analyses 37 questionnaires administered to the same number of auxiliaries of the Judge for the preliminary investigations with reference to the probatory incident on alleged minor victims of sexual abuse. The research wants to examine the real care and protection measures of the alleged victims during the period of time that goes from revelation to judicial hearing and to the moment of the same hearing. Besides, it aims to verify to what extent hearing is a hardship for the child and the eventual correlations between that and some variables about the procedures for the collection of witness, the need of protection and the setting features. The results show, even within the judicial course, a low, late or failed activation of the assistance, protection and care already provided by national rules and international conventions.Key words: auxiliary, probatory procedure, protected hearing, interview.Parole chiave: ausiliario, incidente probatorio, audizione protetta, intervista.

Salmon Fishery

Pink salmon (Oncorhynchus gorbuscha) adults are the smallest of the five Pacific salmon native to the western Pacific Ocean. Pink salmon are also the most abundant of these species and account for a large proportion of the commercial value of the salmon fishery worldwide. A strict two-year life-history of most pink salmon generates temporally isolated populations that spawn either in even-years or odd-years. To uncover the influence of this genetic isolation, reference genome assemblies were generated for each year-class and whole genome re-sequencing data was collected from salmon of both year-classes. The salmon were sampled from six Canadian rivers and one Japanese river. At multiple centromeres we identified peaks of Fst between year-classes that were millions of base-pairs long. The largest Fst peak was also associated with a million base-pair chromosomal polymorphism found in the odd-year genome near a centromere. These Fst peaks may be the result of centromere drive or a combination of reduced recombination and genetic drift, and they could influence speciation. Other regions of the genome influenced by odd-year and even-year temporal isolation and tentatively under selection were mostly associated with genes related to immune function, organ development/maintenance, and behaviour.

There are two main areas of pacific salmon fishing in the Magadan region: Shelikhova Gulf and Tauiskaya Bay. The main fishing species is pink salmon in the region. Its share of total salmon catch by odd-year returns reaches 85 %. Data on the dynamics of escapement to the spawning grounds of pink salmon of the Shelikhova Gulf and Tauiskaya Bay are presented. The displacement of the level of spawning returns of pink salmon into the Shelihova Gulf with the simultaneous reduction of its returns to the Tauiskaya Bay is shown. Data on the dynamics of the fishing indicators of pink salmon for the two main fishing areas are provided. The Tauiskaya Bay as the main pink salmon fishery area loses its importance is shown. Graphical data on the escapement of producers pink salmon to the spawning grounds are presented and the optimal values of spawning escapements are estimated. Chum salmon is the second largest and most fishing species. Information on the dynamics of the number of returns, catch and escapement to the spawning grounds of chum salmon is given. The indicators of escapement to the spawning areas and their compliance with the optimal passes of salmon producers are analyzed. The issues of the dynamics of returns number, catch and the escapement to the spawning grounds of coho salmon producers are considered. The level of the escapement to the spawning areas is shown and the ratio of actual to optimal values of passes is estimated. The role of coho salmon as an object of industrial fishing and amateur fishing is shown. The extent of fishing press on individual groups of salmon populations is discussed. It is concluded that it is necessary to remove the main salmon fishery from the Tauiskaya Bay to the Shelikhova Gulf.

Resumen: La doctrina de Spinoza constituye una de las principales inspiraciones del más célebre entre los idealistas británicos, F.H. Bradley, cuya filosofía se caracteriza a su vez por elementos típicos del idealismo alemán y, en particular, de Hegel. Según A. Seth Pringle-Pattison, la presencia de estas dos tendencias conflictivas reduce el planteamiento de Appearance and Reality a una disposición filosófica esencialmente mística. Sin embargo, a pesar de las reales influencias de Spinoza y Hegel en el contexto del idealismo británico, los cimientos de la metafísica bradleyana (la incognoscibilidad de lo Absoluto, su transcendencia respecto al pensamiento, el rechazo del panteísmo y del panlogismo) sugieren una postura difícilmente identificable con Spinoza o Hegel, o con ambos. Palabras clave: Absoluto - Idealismo británico – Monismo – Panlogismo - Panteísmo.Abstract: Spinoza’s doctrine represents one of the greatest inspirations for the most well-known representative of the British Idealism, F.H. Bradley, whose philosophy is also marked by some of the most typical elements of German Idealism, especially those of Hegel. According to Seth Pringle-Pattison, the presence of these conflictive tendencies reduce the standpoint of Appearance and Reality to an essentially mystic philosophical attitude. However, despite the real influences of Spinoza and Hegel in the context of British Idealism, the foundations of Bradley’s metaphysics (the unknowability of the Absolute and its transcendence, as well as the rejection of pantheism and panlogism) suggest that Bradley is defending a perspective that can hardly be identified with Spinoza or Hegel, or with both of them. Key words: Absolute - British Idealism – Monism – Panlogism - Pantheism.

Contextual Dimension

Understanding the perspectives of knowledge users and the demands of their decision-making environment would benefit researchers looking to enhance the utility of the knowledge they generate. Using the Fraser River Pacific salmon fishery as a case study, we investigate the views of 49 government employees and stakeholders regarding the barriers to incorporating new knowledge into fisheries management. Our study uses analysis of qualitative data structured by a knowledge–action framework, which revealed that 90% of respondents perceived the contextual dimension (e.g., institutional structures and norms) as a barrier for incorporating new knowledge, followed by barriers related to the characteristics of knowledge actors (52% of respondents), characteristics of the knowledge (27%), time and timing (27%), knowledge transfer strategies (17%), and relational dimension (8%). The identified barriers have indirect–direct relationship with knowledge producers and appear hierarchical in nature. We note that informal relationships can enable conditions whereby knowledge users can access new knowledge, and knowledge producers can gain insights on users’ needs. We discuss lessons learned from the case, which we believe can be applied more beyond fisheries.
