Statements About the Pervasiveness of Behavior Require Data About the Pervasiveness of Behavior

2020

Despite recent close attention to issues related to the reliability of psychological research (e.g., the replication crisis), issues of the validity of this research have not been considered to the same extent. This paper highlights an issue that calls into question the validity of the common research practice of studying samples of individuals, and using sample-based statistics to infer generalizations that are applied not only to the parent population, but to individuals. The lack of ergodicity in human data means that such generalizations are not justified. This problem is illustrated with respect to two common scenarios in psychological research that raise questions for the sorts of the…

Graphitically encapsulated cobalt nanocrystal assemblies

2010

Graphitically encapsulated cobalt nanocrystal assemblies are chemically prepared by one-pot reaction at380 degrees C followed by a reversed etching process to produce porous graphitic structure for revealing their self-assembling nature.

THE OCCURRENCE OF CHROMIUM IN RAW MATERIALS AND ITS FATE IN THE BREWING PROCESS

1987

The chromium content of raw materials, intermediate and final products in the brewing process were determined in order to evaluate the contribution of raw materials to the chromium content of beer. The contribution due to beer in the diet is considered in the light of the recommended daily intake of chromium.

IP 3 signalling regulates exogenous RNA i in C aenorhabditis elegans

2015

RNA interference (RNAi) is a widespread and widely exploited phenomenon. Here, we show that changing inositol 1,4,5-trisphosphate (IP3) signalling alters RNAi sensitivity in Caenorhabditis elegans. Reducing IP3 signalling enhances sensitivity to RNAi in a broad range of genes and tissues. Conversely up-regulating IP3 signalling decreases sensitivity. Tissue-specific rescue experiments suggest IP3 functions in the intestine. We also exploit IP3 signalling mutants to further enhance the sensitivity of RNAi hypersensitive strains. These results demonstrate that conserved cell signalling pathways can modify RNAi responses, implying that RNAi responses may be influenced by an animal's physiology…

Characterization of a Double Metal Cyanide (DMC)-Type Catalyst in the Polyoxypropylation Process: Effects of Catalyst Concentration

2014

The alkaline catalysts commonly applied to alkoxylation are characterized by a limited spectrum of activity caused by an irreversible termination of the polyether chains. The presented results show that double metal cyanide (DMC) catalysts reduce or eliminate the aforementioned adverse rearrangement of hydroxyl groups. Moreover, DMC catalysts indicate high activity at low concentrations (ppm range), as expressed by high polymerization rates. It was demonstrated that decreased concentrations of DMC catalyst irreversibly influence its reactivity and the dispersity of the obtained products, as exemplified by the production and determination of selected polyoxypropylenediols at different concen…

Gli insetti edibili alla prova del mercato. Il regolamento di esecuzione (UE) 2021/882 relativo all’immissione in commercio della larva di Tenebrio m…

2021

L’articolo analizza il Regolamento di esecuzione (UE) 2021/882 relativo all’immissione sul mercato della larva di Tenebrio molitor essiccata, ovvero il primo regolamento che autorizza l’immissione di un insetto edibile sul mercato dell’Unione Europea. La normativa in esame fa emergere delle rilevanti criticità in merito all’opportunità e alla sostenibilità delle scelte di tutela della protezione dei dati scientifici ai sensi dell’art. 26 del Regolamento (UE) n. 2283/2015 compiute dal legislatore unionale nel caso in esame. Tale regolamento, inoltre, si presenta come potenziale modello che sarà adottato per le richieste di autorizzazione attualmente al vaglio della Commissione e per le futur…

La economía social como enfoque metodológico, como objeto de estudio y como disciplina científica

1999

This article continues an article written by the same author and published by CIRIEC-España in 1997 (no. 25). It analyses social economy at three cognitive levels: first, as a social reality (Social Economy); second, as a scientific discipline which studies its previous reality (the science of Social Economy); third, as a methodological approach in social sciences (the approach of Social Economy). The author claims that, at these three levels, social economy becomes an alternative way of “making the economy”.

IMPROVEMENT OF THE ASSESSMENT CRITERIA FOR SCIENTIFIC RESEARCH PROJECTS - A PREMISE OF INCREASING THE UNIVERSITY SCIENTIFIC RESEARCH PERFORMANCE

2013

The National Plan for Research, Development and Innovation 2007 – 2013, called herein the National Plan II, represents the main instrument used to implement the National Strategy for Research, Development and Innovation. Universities play a unique role in the development of the knowledge-based society, through its contribution to knowledge generation, transmission, dissemination and utilization. The essential role of the university is to shape the highly qualified human resource, a process that implies a symbiosis between the education and research, the education system performances contributing in this way to a great extent to the society development. The highly qualified human resource re…

Linking scientific and practical knowledge in innovation systems

2011

New research indicates that firms combining the science-based STI (Science, Technology, Innovation) and the experience-based DUI (Doing, Using, Interacting) modes of innovation are more efficient when it comes to improving innovation capacity and competitiveness. With regard to innovation policy, the STI mode calls for a supply driven policy, typically aimed to commercialise research results. The DUI mode suggests a demand driven policy approach, such as supporting the development of new products or services to specific markets. This paper analyses how the two types of innovation policy and the two innovation modes can be combined in regional innovation systems. The analysis builds on studi…
