UVODNIK 2016: PROMJENAMA PREMA BUDUĆNOSTI

By changing its editorial system, the Croatian Journal of Fisheries continues to move towards a more rigorous review which is slowly but surely strengthening its quality and impact. New editors-in-chief have been elected and a co-operation with De Gruyter Open publishers has been established. The official abbreviation of the Journal – CROAT J FISH – was released and it indicated an important change in the manuscript submission process. Also, this Editorial provides information on the articles published in 2015, as well as a list of reviewers who participated in the review process.Promjenom uredničkog sustava i njegovog načina rada, časopis se nastavlja kretati u pravcu rigoroznijih recenzija što, polagano ali sigurno, jača njegovu kvalitetu i utjecaj. Izabrani su novi glavni urednici časopisa i uspostavljena je suradnja s izdavačkom kućom De Gruyter Open. Objavljena je službena kratica časopisa – Croat J Fish - te je naznačena važna promjena kod prijave radova u CJF-u. Također, uvodnik daje podatke objavljenih članaka u 2015. godini prema tematskim cjelinama, kao i popis recenzenata koji su sudjelovali u recenzijskom postupku

UVODNIK 2015: NAPORI PREMA BOLJOJ KVALITETI ČASOPISA Croatian Journal of Fisheries (Ribarstvo)

By changing its editorial system, the Croatian Journal of Fisheries is moving toward more rigorous review which will sub- sequently strengthen its quality and impact. This editorial provides information on the published articles in 2014 as well as a list of reviewers who participated in the review process. Many papers were submitted as short communications to the Threatened Fishes of the World (TFW) series in 2014. To be more useful to the broader scientific community, guidelines about preparation of manuscripts for the TFW series based on The IUCN Red List of Threatened SpeciesTM is provided. Also, after having several years of experience in reviewing, processing and editing of manuscripts, it has been noted that authors repeat the same mistakes. Therefore, we present here a paper that discusses the most common mistakes encountered dur- ing manuscript preparation which can result in its rejection.Promjenom uredničkog sustava i načina rada časopis se kreće u pravcu rigoroznijih recenzija te sukladno, jačanju kvalitete i utjecaja. Ovaj uvodnik daje podatke objavljenih članaka u 2014. godini prema tematskim cjelinama kao i popis recenzenata koji su sudjelovali u recenzijskom postupku. Mnogo kratkih članaka je pristiglo iz tematike ugroženih ribljih vrsta u svijetu u 2014. Stoga su ovdje date detaljne upute za pripremu takvih članaka, baziranih na podacima navedenim u The IUCN Red List of Threatened SpeciesTM , kako bi bili korisniji za širu znanstvenu zajednicu. Također, nakon više godina praćenja pridošlih članaka, autori često i kontinuirano griješe u oblikovanju samog članka. Stoga je dat i prikaz najčešćih pogrešaka kod prijavljenih radova što može rezultirati istovremenim odbijanjem rada kao potencijalnog članka za publiciranje

Cuantificación de la Pérdida de Bienestar Asociada a la Imposición de Restricciones en la Optimización de Carteras de las Administradoras de Fondos de Retiro.

Las restricciones impuestas por organismos reguladores al diseño de carteras de administradoras de fondos de retiro, pretenden orientar el comportamiento de las administradoras, no obstante estas restricciones conllevan pérdida de bienestar por parte de los ahorristas. En el presente trabajo se cuantifica, en forma numérica, la pérdida de bienestar asociado a diferentes restricciones posibles. Para ello se utilizan técnicas de programación matemática, las que permiten a la vez obtener en forma rápida portafolios óptimos en el marco de tales restricciones. Un ejemplo numérico pretende ayudar a entender la situación creada.

Tastes and Singular Economies

The object of this paper is to show some examples of economies in which singular equilibria occur as a consequence of utility functions and where this equilibria play a crucial rolle to understand the behavior of the economy as a system. An economy will be called singular if little changes in the tastes of the consumer imply big changes in the equilibria set.
