Consumers' use of nutrition-related endorsement symbol to help their purchase decisions: An extension of the theory of planned behaviour

Tutkimuksessa haluttiin selvittää, mitkä tekijät vaikuttavat ravintoon liittyvän suositusmerkin käyttöön kuluttajan ostopäätöksen apuna. Tutkimuksen viitekehyksen pohjaksi valittiin suunnitellun toiminnan teoria, joka on osoittautunut selittämään hyvin useaa ravintoon- ja terveyteen liittyvää käyttäytymistä. Tutkimustoteutettiin kyselytutkimuksella, jonka aineisto kerättiin Internetissä julkaistulla kyselylomakkeella. Tulokset osoittivat, että kuluttajan aikomus käyttää suositusmerkkiä oli mallin vahvin selittäjä. Lisäksi merkin käyttöä selitti kuluttajan kokema sisäinen kontrolli, johon ulkoinen kontrolli vahvasti vaikuttaa. Ostopäätössitoutumisen havaittiin vaikuttavan aikomuksen ja todellisen merkin käytön väliseen yhteyteen. Yleisesti tulokset osoittivat, että kuluttajilla on aikomusta käyttää merkkiä, mutta todellinen käyttö on huomattavasti vähäisempää.

Alcohol expectancies and alcohol outcomes: effects of the use of protective behavioral strategies.

OBJECTIVE: Alcohol expectancies (AEs) are positively associated with drinking behaviors, whereas the use of protective behavioural strategies (PBS) is negatively related to alcohol outcomes among young adults. PBS have been shown to weaken relationships between some alcohol risk factors and alcohol outcomes. This study aimed to examine longitudinally the moderating effect of PBS on the relationships between AEs and alcohol outcomes among young adults. METHOD: Participants (N = 188; 61.7% female) were U.S. young adults participating in a larger longitudinal study. Measures of PBS, AEs, alcohol use, and related consequences were used from the baseline and 12-month follow-up assessments. RESULTS: Negative binomial hurdle models found that PBS (total score) significantly moderated the relationship between positive AEs and consequences, such that among high school seniors endorsing higher positive AEs, those using more PBS in high school reported fewer negative consequences 1 year later. PBS (Manner of Drinking) also moderated the relationship between negative AEs and alcohol use, revealing the use of PBS in high school as having a protective function against later drinking among participants with high positive AEs. Last, PBS (Serious Harm Reduction) significantly moderated the associations between positive AEs and alcohol use and between negative AEs and consequences, such that participants with higher AEs and higher PBS use in high school were at greatest risk for drinking and experiencing negative consequences later. CONCLUSIONS: Overall, these findings suggest that PBS use may be protective by weakening relationships between positive AEs and alcohol outcomes. Limitations and future directions are discussed.

Use of amitriptyline for the treatment of chronic tension-type headache. Review of the literature

Amitriptyline is a tricyclic antidepressant, considered the treatment of choice for different types of chronic pain, including chronic myofascial pain. Its antinociceptive property is independent of its antidepressant effect. Although its analgesic mechanism is not precisely known, it is believed that the serotonin reuptake inhibition in the central nervous system plays a fundamental role in pain control. Although this medication is widely used in the prevention of chronic tension-type headache, few studies have investigated the efficacy of this treatment and the published results are contradictory. The objective of this article was to review the literature published on the use of amitriptyline in the prophylactic treatment of chronic tension-type headache, considering the level of scientific evidence of the different studies using the SORT criteria. From this review, 5 articles of evidence level 1, and another 5 articles of evidence level 2 were selected. Following analysis of the 10 studies, and in function of their scientific quality, a level A recommendation was made in favor of using amitriptyline in the treatment of chronic tension-type headache.

Análisis del proceso de adquisición del código audiovisual y de la intervención de los agentes que forman a los ciudadanos en el conocimiento de los medios

The research group Gre‐TICE (Grupo de investigación en tecnologías de la Información y la Comunicación en Educación) has the acquisition of the multimedia language and their use as a form of expression as one of their lines of research. During the academic year 2002‐ 2003, following previous work in the use of ICT in Education, commenced upon the project: “The acquisition of visual and sound codes and the processes related to the visual media”. The intention of this project is to study how formal or non‐formal education context can help young adults and children to acquire visual and sound codes to become ‘critical consumers’ with the media and to use the tools in a creative way. To achieve this objective, the project team has developed a partner group which includes professional from different European regions; including teachers and managers from across the age spectrum, government institutions and cultural organisations. Whilst the project will call upon qualitative analysis of the previous projects / research, it will seek to develop ‘Good Practice’ guides and other resources/ materials to be disseminated to project partners (and others) to build innovative actions throughout the European region

THE ROLE OF NANOMATERIALS IN COSMETICS: NATIONAL AND INTERNATIONAL LEGISLATIVE ASPECTS

Nanotechnology is currently one of the fastest growing scientific fields. The products of this science have become part of our everyday lives. However, to date, regulatory agencies have not yet established a single definition for nanomaterials and nanotechnology. Therefore, each country has its own definitions and legislation to control products containing nanomaterials. Being relatively new materials, there are no long-term studies showing their impact on human health and the environment. Consequently, countries control the amount of nanomaterials present in cosmetics, allowing the end consumer to choose which cosmetic to use, by choosing products with or without nanomaterials. Therefore, the primary objective of this study was to identify the most used nanomaterials in cosmetics and verify whether these formulations are in accordance with the laws in force in the United States, the European Union and Brazil, thereby determining if the cosmetics on the market are in line with the existing laws in these three economic powers. This study is unique and will contribute to furthering the discussion on existing laws pertinent to the use of nanotechnology in cosmetics.

Characterisation of Laser Beam and Paper Material Interaction

It is known already from 1970´s that laser beam is suitable for processing paper materials. In this thesis, term paper materials mean all wood-fibre based materials, like dried pulp, copy paper, newspaper, cardboard, corrugated board, tissue paper etc. Accordingly, laser processing in this thesis means all laser treatments resulting material removal, like cutting, partial cutting, marking, creasing, perforation etc. that can be used to process paper materials. Laser technology provides many advantages for processing of paper materials: non-contact method, freedom of processing geometry, reliable technology for non-stop production etc. Especially packaging industry is very promising area for laser processing applications. However, there are only few industrial laser processing applications worldwide even in beginning of 2010´s. One reason for small-scale use of lasers in paper material manufacturing is that there is a shortage of published research and scientific articles. Another problem, restraining the use of laser for processing of paper materials, is colouration of paper material i.e. the yellowish and/or greyish colour of cut edge appearing during cutting or after cutting. These are the main reasons for selecting the topic of this thesis to concern characterization of interaction of laser beam and paper materials. This study was carried out in Laboratory of Laser Processing at Lappeenranta University of Technology (Finland). Laser equipment used in this study was TRUMPF TLF 2700 carbon dioxide laser that produces a beam with wavelength of 10.6 μm with power range of 190-2500 W (laser power on work piece). Study of laser beam and paper material interaction was carried out by treating dried kraft pulp (grammage of 67 g m-2) with different laser power levels, focal plane postion settings and interaction times. Interaction between laser beam and dried kraft pulp was detected with different monitoring devices, i.e. spectrometer, pyrometer and active illumination imaging system. This way it was possible to create an input and output parameter diagram and to study the effects of input and output parameters in this thesis. When interaction phenomena are understood also process development can be carried out and even new innovations developed. Fulfilling the lack of information on interaction phenomena can assist in the way of lasers for wider use of technology in paper making and converting industry. It was concluded in this thesis that interaction of laser beam and paper material has two mechanisms that are dependent on focal plane position range. Assumed interaction mechanism B appears in range of average focal plane position of 3.4 mm and 2.4 mm and assumed interaction mechanism A in range of average focal plane position of 0.4 mm and -0.6 mm both in used experimental set up. Focal plane position 1.4 mm represents midzone of these two mechanisms. Holes during laser beam and paper material interaction are formed gradually: first small hole is formed to interaction area in the centre of laser beam cross-section and after that, as function of interaction time, hole expands, until interaction between laser beam and dried kraft pulp is ended. By the image analysis it can be seen that in beginning of laser beam and dried kraft pulp material interaction small holes off very good quality are formed. It is obvious that black colour and heat affected zone appear as function of interaction time. This reveals that there still are different interaction phases within interaction mechanisms A and B. These interaction phases appear as function of time and also as function of peak intensity of laser beam. Limit peak intensity is the value that divides interaction mechanism A and B from one-phase interaction into dual-phase interaction. So all peak intensity values under limit peak intensity belong to MAOM (interaction mechanism A one-phase mode) or to MBOM (interaction mechanism B onephase mode) and values over that belong to MADM (interaction mechanism A dual-phase mode) or to MBDM (interaction mechanism B dual-phase mode). Decomposition process of cellulose is evolution of hydrocarbons when temperature is between 380- 500°C. This means that long cellulose molecule is split into smaller volatile hydrocarbons in this temperature range. As temperature increases, decomposition process of cellulose molecule changes. In range of 700-900°C, cellulose molecule is mainly decomposed into H2 gas; this is why this range is called evolution of hydrogen. Interaction in this range starts (as in range of MAOM and MBOM), when a small good quality hole is formed. This is due to “direct evaporation” of pulp via decomposition process of evolution of hydrogen. And this can be seen can be seen in spectrometer as high intensity peak of yellow light (in range of 588-589 nm) which refers to temperature of ~1750ºC. Pyrometer does not detect this high intensity peak since it is not able to detect physical phase change from solid kraft pulp to gaseous compounds. As interaction time between laser beam and dried kraft pulp continues, hypothesis is that three auto ignition processes occurs. Auto ignition of substance is the lowest temperature in which it will spontaneously ignite in a normal atmosphere without an external source of ignition, such as a flame or spark. Three auto ignition processes appears in range of MADM and MBDM, namely: 1. temperature of auto ignition of hydrogen atom (H2) is 500ºC, 2. temperature of auto ignition of carbon monoxide molecule (CO) is 609ºC and 3. temperature of auto ignition of carbon atom (C) is 700ºC. These three auto ignition processes leads to formation of plasma plume which has strong emission of radiation in range of visible light. Formation of this plasma plume can be seen as increase of intensity in wavelength range of ~475-652 nm. Pyrometer shows maximum temperature just after this ignition. This plasma plume is assumed to scatter laser beam so that it interacts with larger area of dried kraft pulp than what is actual area of beam cross-section. This assumed scattering reduces also peak intensity. So result shows that assumably scattered light with low peak intensity is interacting with large area of hole edges and due to low peak intensity this interaction happens in low temperature. So interaction between laser beam and dried kraft pulp turns from evolution of hydrogen to evolution of hydrocarbons. This leads to black colour of hole edges.

Balises pour l’intervention avec les technologies auprès des élèves qui ont des incapacités intellectuelles

Considérées comme des moyens incontournables de participation à la société, les technologies de l’information et de la communication (TIC) constituent une piste de solution prometteuse pour l’enseignement et l’apprentissage auprès des élèves qui ont des incapacités intellectuelles. Toutefois, plusieurs auteurs dénoncent la faible utilisation des TIC en éducation de ces élèves. Pire encore, les recherches sur le sujet génèrent des résultats intéressants, mais d’une contribution limitée pour l’avancement des connaissances dans le domaine. Guidées par l’intuition et par un enthousiasme empirique évident, ces recherches s’appuient rarement sur des cadres de référence. Certes la documentation scientifique foisonne de champs de savoirs qui peuvent contribuer à ce domaine, mais ces contributions sont parcellaires et peu adaptées aux spécificités de ce dernier. L’intervention avec les TIC auprès des élèves qui ont des incapacités intellectuelles demeure donc un champ conceptuel mal défini qui n'est légitimé par aucun cadre de référence en particulier. Cette recherche doctorale se situe en phase de préconception d’un modèle de l’intervention avec les TIC auprès des élèves qui ont des incapacités intellectuelles. Elle vise à mettre en place des balises solides pouvant servir de cadre à l’élaboration d’un modèle de cette intervention. Dans cette phase de préconception, nous poursuivons deux objectifs, à savoir : 1) la mise au point d’un référentiel qui constitue un cadre intégrateur des connaissances existantes en la matière, qui servira avant tout à structurer et à organiser les informations disponibles à l’intérieur d’une synthèse validée par des experts et des intervenants oeuvrant auprès de ce type d’élèves et 2) l’élaboration d’un cahier des charges fonctionnel qui s’appuie sur le référentiel développé et qui précise les fonctions qu’un modèle idéal de l’intervention avec les TIC auprès des élèves qui ont des incapacités intellectuelles devrait remplir pour répondre pleinement aux besoins de ses différents utilisateurs. Ces balises (le référentiel et le cahier des charges fonctionnel) sont destinées, principalement, à des chercheurs, des concepteurs de technologies, des formateurs d’enseignants, etc. Les élèves, les enseignants et autres agents de l'éducation pourront en bénéficier indirectement à travers les applications dérivées de ces balises (programmes de formation, technologies, recherches, scénarios pédagogiques, etc.).

O ensino da língua portuguesa e a linguagem na comunicação virtual: alternativas e dilemas

A presente investigação tem como objetivo compreender como os professores de Língua Portuguesa integram a linguagem da comunicação pela Internet em sua prática pedagógica, uma vez que a linguagem utilizada na comunicação virtual demonstra variações linguísticas na expectativa oposta a Língua Portuguesa em sua forma padrão e, neste contexto, a escola e o professor de português representam intermédios possíveis entre o escrito padrão e o virtual. Após processo investigativo que contou com recolha de dados documentais e entrevistas semiestruturadas, constata-se que os professores de Língua Portuguesa ressaltam as diferenças da linguagem na comunicação pela Internet em relação à forma padrão na mesma precisão em que defendem o uso da tecnologia no ambiente escolar. Afirmam que, neste contexto, o papel do professor de português concentra-se no preparo do estudante para o uso da forma padrão, permitindo uma abertura em sua prática à linguagem na comunicação virtual. Neste sentido, defendem que o posicionamento adequado do professor de Língua Portuguesa diante do ensino da língua padrão e sua relação com a linguagem virtual, centraliza-se numa abertura para um estudo linguístico na perspectiva dos possíveis usos sociais da língua, possuindo como referencial a forma padrão da Língua Portuguesa.

The determinants of online loan applications from small businesses

Purpose – The purpose of this paper is to examine both the characteristics of the business customers and the types of venture which make use of online loan applications. Despite the growth in the use of technology in banking and the advent of online banking, little research has been conducted on the factors underlying online loan application behaviour amongst business banking customers. Design/methodology/approach – A multivariate analysis is conducted on a USA dataset to empirically test the hypotheses derived in this paper. The empirical evidence is drawn from the US Survey of Small Business Finances, which contains 3,561 sample ventures, representing 5.3 million small businesses in the USA. Findings – The paper finds that online loan behaviour is largely determined by the characteristics of the entrepreneur, rather than that of the venture. It is also found that factors that trust, evident in the length of the relationship between the applicants and their primary lender, is important. Moderating these effects is further evidence that suggests the number of lenders and distance between lenders and applicants has a marked effect on online loan behaviour. Originality/value – This paper identifies the factors determining small business online loan application behaviour. This is important because the nature of online loan behaviour is changing the existing relationships between banks and customers. Whilst online loan applications afford banks the opportunity to substantially reduce costs, the danger is that long term relationships with customers are harder to cement.
