Long-term changes in habitat and trophic level of Southern Ocean squid in relation to environmental conditions
Long-term studies of pelagic nekton in the Southern Ocean and their responses to ongoing environmental change are rare. Using stable isotope ratios measured in squid beaks recovered from diet samples of wandering albatrosses Diomedea exulans, we assessed decadal variation (from 1976 to 2016) in the habitat (δ13C) and trophic level (δ15N) of five important Southern Ocean squid species in relation to indices of environmental conditions—Southern Oscillation Index (SOI) and Southern Annular Mode (SAM). Based on δ13C values, corrected for the Suess effect, habitat had changed over the last 50 years for Taonius sp. B (Voss), Gonatus antarcticus, Galiteuthis glacialis and Histioteuthis atlantica but not Moroteuthopsis longimana. By comparison, mean δ15N values were similar across decades for all five species, suggesting minimal changes in trophic levels. Both SAM and SOI have increased in strength and frequency over the study period but, of the five species, only in Taonius sp. B (Voss) did these indices correlate with, δ13C and δ15N values, indicating direct relationships between environmental conditions, habitat and trophic level. The five cephalopod species therefore changed their habitats with changing environmental conditions over the last 50 years but maintained similar trophic levels. Hence, cephalopods are likely to remain important prey for top predators in Southern Ocean food webs, despite ongoing climate change

Tratamientos Psicológicos Empíricamente Apoyados Para Adultos: Una Revisión Selectiva [Evidence-Based Psychological Treatments for Adults: A Selective Review]
Antecedentes: los tratamientos psicológicos han mostrado su efi cacia,
efectividad y efi ciencia para el abordaje de los trastornos mentales; no
obstante, considerando el conocimiento científi co generado en los últimos
años, no se dispone de trabajos de actualización en español sobre cuáles
son los tratamientos psicológicos con respaldo empírico. El objetivo fue
realizar una revisión selectiva de los principales tratamientos psicológicos
empíricamente apoyados para el abordaje de trastornos mentales en personas
adultas. Método: se recogen niveles de evidencia y grados de recomendación
en función de los criterios propuestos por el Sistema Nacional de Salud
de España (en las Guías de Práctica Clínica) para diferentes trastornos
psicológicos. Resultados: los resultados sugieren que los tratamientos
psicológicos disponen de apoyo empírico para el abordaje de un amplio
elenco de trastornos psicológicos. El grado de apoyo empírico oscila de bajo
a alto en función del trastorno psicológico analizado. La revisión sugiere
que ciertos campos de intervención necesitan una mayor investigación.
Conclusiones: a partir de esta revisión selectiva, los profesionales de la
psicología podrán disponer de información rigurosa y actualizada que les
permita tomar decisiones informadas a la hora de implementar aquellos
procedimientos psicoterapéuticos empíricamente fundamentados en
función de las características de las personas que demandan ayuda.
// Evidence-Based Psychological Treatments for Adults: A Selective Review. Background: Psychological treatments have shown their effi cacy,
effectiveness, and effi ciency in dealing with mental disorders. However,
considering the scientifi c knowledge generated in recent years, in the
Spanish context, there are no updating studies about empirically supported psychological treatments. The main goal was to carry out a selective
review of the main empirically supported psychological treatments for
mental disorders in adults. Method: Levels of evidence and degrees of recommendation were collected based on the criteria proposed by the Spanish National Health System (Clinical Practice Guidelines) for different
psychological disorders. Results: The results indicate that psychological
treatments have empirical support for the approach to a wide range of
psychological disorders. These levels of empirical evidence gathered range from low to high depending on the psychological disorder analysed.
The review indicates the existence of certain fi elds of intervention that
need further investigation. Conclusions: Based on this selective review,
psychology professionals will be able to have rigorous, up-to-date information that allows them to make informed decisions when implementing
empirically based psychotherapeutic procedures based on the characteristics of the people who require help

Opening the black box of accounting for Greenhouse Gas Emissions: The different views of institutional bodies and firms
This paper highlights the current accounting approaches to greenhouse gas (GHG) emissions. In
particular, it explores and critically discusses the treatment of emission rights (ER) under carbon trading
schemes from two distinct angles. On the one hand, it reviews the domestic solutions adopted by accounting
bodies and, on the other, it examines current practices followed by firms in the European
Energy Exchange (EEX). Regarding the former group, there are substantial differences, which would
suggest some potential difficulties in finding a common solution for the future. Not surprisingly, there is
still a diversity of approaches with regard to how firms report ER. Although the most common practice is
not to include free ER in the main financial statements, the proportion of firms that recognize both ER
and liabilities is larger than in prior studies (Warwick and Ng, 2012; Lovell et al., 2010; Ascui and Lovell,
2012; Black, 2013). Leaving aside sample differences, the new auctioning system introduced by Phase 3 of
the European Emission Trading Scheme (EU ETS) may have affected firm behavior. Furthermore, it is also
worth pointing out the decrease in non-disclosure. Interestingly, we show that local accounting rules on
ER issued by EU bodies do not generally affect corporate financial reporting. To the extent this study
updates the knowledge about current institutional developments and company practices on ER, it could
help the International Accounting Standard Board (IASB) to develop a standard
