Emotional connections to books and technological innovations : an e-book perspective

E-book devices are a technological innovation that has been mass marketed to consumers as a revolution in the way that books will be read and stored. This paper extends previous research on technology adoption behaviour of individuals by focusing on the role of emotional connections people have towards e-books. A number of technology adoption models can explain the adoption of e-book devices such as the technology acceptance model, theory of planned action, theory of reasoned action and social cognitive theory. Due to the increased importance of social learning on a person’s behaviour, social cognitive theory is identified in this paper as being the most appropriate theoretical lens to understand the emotional connections a person has towards e-books. The findings from this paper may help to fill the gaps in academic discussion about what theory best explains a person’s behavioural intention towards technological innovations and the impact of marketing on this behaviour. In addition, the paper has a number of managerial implications including identifying the importance of an emotional connection to a technological innovation that influences the adoption process. The emphasis on emotional connection as mediating the way a person receives information about e-book devices may help to influence future marketing efforts of new technologies.

Historiographic foodways: a survey of food and drink histories in Australia

This essay is a survey of the field of food and drink history in Australia since the 1970s. It discusses the range of research and picks out key historiographic aspects: the search for an Australian cuisine; regional food cultures; connection between sources and historical interpretation; and the interdisciplinarity of food and drink history. It suggests that as food and drink histories have broadened beyond a search for culinary traditions and a gastronomic sensibility, so our understanding of food and drink in Australian history has deepened. It also argues that food and drink history is more than textual knowledge in books and articles: television programs and exhibitions held in museums and libraries, for example, have enhanced our understanding of food and drink histories.

Infrared face recognition: a comprehensive review of methodologies and databases

Automatic face recognition is an area with immense practical potential which includes a wide range of commercial and law enforcement applications. Hence it is unsurprising that it continues to be one of the most active research areas of computer vision. Even after over three decades of intense research, the state-of-the-art in face recognition continues to improve, benefitting from advances in a range of different research fields such as image processing, pattern recognition, computer graphics, and physiology. Systems based on visible spectrum images, the most researched face recognition modality, have reached a significant level of maturity with some practical success. However, they continue to face challenges in the presence of illumination, pose and expression changes, as well as facial disguises, all of which can significantly decrease recognition accuracy. Amongst various approaches which have been proposed in an attempt to overcome these limitations, the use of infrared (IR) imaging has emerged as a particularly promising research direction. This paper presents a comprehensive and timely review of the literature on this subject. Our key contributions are (i) a summary of the inherent properties of infrared imaging which makes this modality promising in the context of face recognition; (ii) a systematic review of the most influential approaches, with a focus on emerging common trends as well as key differences between alternative methodologies; (iii) a description of the main databases of infrared facial images available to the researcher; and lastly (iv) a discussion of the most promising avenues for future research. © 2014 Elsevier Ltd.

Accommodating taboo language in English language teaching: issues of appropriacy and authenticity

Culturally specific language practices related to vernacular uses of taboo language such as swearing represent a socially communicative minefield for learners of English. The role of classroom learning experiences to prepare learners for negotiation of taboo language use in social interactions is correspondingly complicated and ignored in much of the language teaching research literature. English language teachers confront not only obstacles to effective development of sociolinguistic and cultural knowledge in classroom instruction, and failure of course-books to address taboo language, but also uncertainties they themselves have about addressing such obstacles and omissions. In this paper, we draw on interview data from three experienced teachers of English as an additional language, to explore their perceptions and classroom practices in relation to taboo language. In particular, we explore the situational appropriateness of mild taboo swearing using the lexical item, bloody, which has a strong positioning in Australian language culture. Dilemmas surrounding this potentially troublesome item of Australian English are foregrounded in relation to the extent to which often neglected, but widely used taboo language is actually ‘taboo’ in the classroom.

Catálogo dos livros de Horas da Biblioteca Nacional do Brasil

O presente trabalho objetivou identificar a coleção dos livros de horas da Biblioteca Nacional do Brasil, com vistas a produzir um catálogo. A coleção abrange nove livros manuscritos iluminados; neste trabalho, porém, foram identificados apenas os oito livros produzidos na segunda metade do século XV. Quatro desses livros são provenientes da Real Biblioteca – Casa do Infantado, que veio para o Brasil em 1808 com a família real portuguesa, tornando-se o núcleo inicial da Biblioteca Nacional brasileira. Na primeira parte apresentamos as considerações teóricas situando o período no qual o livro de horas se inscreve, destacando a sua importância, tanto na sociedade quanto no desenvolvimento da piedade do homem na cristandade medieval.

Effects of maturation and scarification on seed germination of Syagrus schizophylla (Mart.) glass. (Arecaceae)

Syagrus schizophylla (Mart.) Glass. belongs to the Arecaccae family. This palm is native of Brazil and presents great potential for use in gardens and cultivation in pot. Palms species, with relatively few exceptions, can only be propagated from seeds; even so, there are no reports in the literature about the germination of this palm seeds. The seed maturity is a factor that interferes in the success of the germination process. For some species, studies showed that palm seeds germinated better when the fruits were completely ripe (showing full color) and for other, when they were with green coloration. Several species of the Arecaccae family presents physical dormancy of seeds in varied degrees, demanding treatments for improve germination. The objective of this work was to study the effects of maturation and of the scarification on seed germination of S. schizophylla. The experimental design used was a factorial 3 x 2 (3 maturation stadiums: green, half-ripe - yellow and completely ripe - red; and mechanical scarification: with and without), entirely casualized, with four replications of 15 seeds per plot. The seeds (with 32,43% of humidity) were placed in plastic boxes with sand (60% of humidity, placing water according to weight in each three days), under controlled conditions of alternated temperature of 25-35 degrees C, photoperiod of 12 hours. The percentage of germination and the speed germination index (SGI) were evaluated until 79 days. It was observed that, so much for germination percentage as for SGI, there was not significant difference for the interaction among the two factors, maturation stadium and scarification, however, there were significant differences among the maturation stadiums and between seeds scarified or not. The seeds from green fruits presented lower germination percentage and slower germination when compared with seeds from yellow or red fruits; the seeds from yellow or red fruits didn't differ statistically to each other. To seeds scarificated, independently of the maturation stadium, presented germination percentage significantly larger and the germination was significantly faster when compared with the seeds without scarification.

Effect of type of cuttings and indolbutyric acid on the rooting of rose (Rosa sp. 'Red success') leafy cuttings during two seasons

The objectives of this study were to evaluate the effect of type of cuttings (apical, intermediate and basal) and different concentrations of IBA (indole-3-butyric acid) on rooting of Red success rose (Rosa sp.) leafy cuttings, during two season of cuttings collection (summer and winter). The investigation was carried out in the farm Irmaos Van Schaik in Holambra-SP, Brazil, from February to April and August to October/1993. The experimental design was a randomized block in a factorial arrangement. It consisted of 12 treatments (3 types of cuttings combined with IBA powder in 4 different concentrations - 0, 1000, 2000 and 4000 ppm) with 3 replicates during 2 seasons. The investigation permitted the following conclusions: the apical and intermediate cuttings showed better results in general when compared to the basal ones in both seasons; the average rooting at the transplanting time were 76%, 70% and 47% (summer) and 80%, 69% and 33% (winter) for apical, intermediate and basal cuttings, respectively; the utilization of IBA did not stimulate rooting. The average rooting for the control cuttings reached 85% (summer) and 78% (winter), regardless the type of cuttings.

Influence of organic and chemical fertilization on the yield of flowers, contents and composition of essential oil of (Chamomilla recutita (L.) Rauschert)

A field experiment was conducted with chamomile (Chamomilla recutita [L.] Rauschert), in an area of the Olericulture and Medicinal Plants of the Horticulture Department at UNESP - Jaboticabal Campus, with the aim to evaluate the influence of organic and chemical fertilization on the yield of flowers, and content and composition of the essential oil of chamomile. The experimental design for the yield of flowers consisted of randomized blocks with 7 treatments and 4 replications, for the analysis of the contents and composition of the oil, the completely randomized block was used and for analysis of the correlation between harvesting and treatment, the split-plot design into randomized blocks was used. The treatments tested were: no fertilization, green manure (Mucuna aterrima + Crotalaria spectabilis), green manure (plant cocktail), organic fertilizer (farmyard manure), N as urea, N as ammonium sulphate, NPK with N supplement as ammonium sulphate. There was no influence of the treatments on the yield of flowers nor on the essential oil content; on the other hand both characteristics did show significant differences in harvesting times (Tukey 5%). The main yield was 885.90 kg/ha dry flowers and the mean oil content was 0,86%. The green manure treatment (M. aterrima + C. spectabilis) showed a higher percentage of chamazulene content, with a highly significant difference in harvesting times (Tukey 1%). The a-bisabolol percentages did not evidence significant differences between treatments. However, among harvesting times, there was a variation. A negative correlation was verified between the chamazulene and abisabolol percentages; the first increasing - from 21.02 to 36.17% - and the latter decreasing - from 14.12 to 8.72 % - from the first to the sixth harvest. The observed mean content of chamazulene was 14.64 % and a-bisabolol was 16.72 %.

Diurnal and seasonal variations of CWSI and non-water-stressed baseline with nectarine trees

The work described was part of the programme, Innovative biological indicators to improve the efficiency of water and nitrogen use and the fruit quality in tree crops Project, a partnership between ISA and INRA. Field studies were conducted in Portugal on different irrigated plots of nectarine trees; a fully irrigated (unstressed plot) and a plot that was not irrigated for some days (stressed plot). The aim of this work was to investigate the effects of plant water stress on canopy temperature, to determine the nonwater-stressed baseline and to observe diurnal and seasonal variations of Crop Water Stress Index (CWSI). Canopy temperature, psychrometric and wind speed data were taken each half-hour, between 9:30 and 15:30 h. Results showed that canopy temperature was higher during the daytime, for both unstressed and stressed plots. A linear regression of canopy-air temperature differential and the vapor pressure deficit (non-water-stress baseline) showed a r2= 0.65. During the stress period, the average canopy temperature of the stressed plot was up to 5.4°C higher than the unstressed plot. Diurnal and seasonal average of CWSI values showed differences between unstressed and stressed plots, during the stress period.

Productivity of beet and roquette cultivation as a function of time of establishing intercropping

With the aim of evaluating the effect of intercropping on the productivity of beet and roquette crops, a study was conducted in the Section of Vegetable and Aromatic-Medicinal Plants, FCAV-UNESP, Jaboticabal/SP. The treatments consisted of co-cultivations of roquette (Cultivada) and beets (Early Wonder) established at 0, 7, 14 and 21 days after the transplanting of beets, and as monocultures of beets and roquette. The experiments were delineated in a randomized block design. The productivity of beets in monoculture was not superior to that obtained with intercropping with roquette. The production of dry mass of roquette with intercropping was less than that with monoculture and the reduction was more marked with more delayed establishment of co-cultivation. Intercropping established at 0 and 7 days after the transplanting of beets was the most efficient, with indices of efficient use of land of 1.26 and 1.27, respectively.
