    The phytochemicals including flavonoids and phenolic acids mainly contained in the outer layer of the kernels are key factors responsible for the biofunctionality of whole grains. The phytochemical profiles of twelve grain samples comprising 6 wheats, 3 barleys and 3 oats were studied for comparative evaluation of their antioxidant properties. Total phenolic content (TPC) and antioxidant activities (DPPH and ORAC) of the grain extracts were measured. The bound phenolic acids were identified and quantified using HPLC and mass spectrometry. The flavonoids in different grain were analyzed using HPLC and tandem mass spectrometric techniques. TPC in acidified methanol extracts ranged from 164 to 226, 264-391, and 308-331 mg/100 g for wheat, oats and barley, respectively. Similarly TPC in acetone extracts were 78 to 118, 223 to 351 and 367 to 433 mg/100 g. Acetone extracts had significantly (p < 0.05) higher TPC than acidified methanol extracts for barley samples. On the contrary, acidified methanol extracts from wheat and oats had higher TPC than their acetone extracts. The results showed that for both acetone and acidified methanol extracts, barley samples had significantly higher antioxidant activity than oats and wheat samples although even some of the oats had similar or even higher TPC compared to barley samples. Wheat extracts had low antioxidant activity assayed using both DPPH and ORAC assays. Oats had the highest levels of bound phenolic acids (431 to 656 mg/100 g) followed by wheat samples (91 to 153 mg/100 g). The bound phenolic acid contents of barley samples ranged from 81–105 mg/100 g. The major flavonoids in barley samples are dimers and trimers of proanthocyanidins, while flavone glucosides are the major flavonoids for wheat. The phytochemical including flavonoid profile may explain the antioxidant activity for different cereal grain rather than TPC

    Attributes of graduate entry nurses: An integrative review

    Get PDF
    Second degree graduate entry (GEN) programmes transition graduates into the nursing workforce using the candidate’s first degree to fast track a career change. This presentation explores the attributes of graduate entry nurses as background to developing a graduate entry Master of Health Science degree in nursing. A qualitative integrative review approach was used to synthesise the findings of 24 published research reports on attributes of graduate entry nurses. Data bases searched included CINAHL, Proquest, Science Direct, and open source data bases included Pubmed, DOAJ and CORE, using keywords ‘graduate entry nursing’, ‘academic performance’, ‘readiness for practice’, ‘socialisation’, and ‘perceptions’. The Critical Appraisal Programmes (CASP, 2017) Checklist was used to ascertain the quality, relevance and validity of the articles identified in the database and other search approaches. A thematic synthesis approach (Thomas & Harden, 2008) was used to analyse the qualitative information presented as findings in the articles. This approach used three levels of analysis; coding of text line by line, the identification of descriptive themes, and the creation of analytical themes. Descriptive themes were used to group statements from the text of the articles, and analytical themes were developed as interpretive explanations created in the conceptual synthesis. The analytical themes developed included; confidence, motivation, and competence as learners; emotional intelligence within relationships; focus on research-based practice; and challenges for faculty. GEN students require professional socialisation that takes account of the attributes they bring to nursing. GENs need educational approaches and supervision that offer opportunities for critical reflection and peer support

    Enacting Trust

    Small and removed from the Spanish mainland, the Enclave of Ceuta has always depended on flows of goods and labour out of the Moroccan hinterland, with individuals from different ethnic and religious groups forming informal, flexible and personal economic bonds based on mutual ‘confianza’ (trust). Since its entry into the European Union in 1986, the Spanish government has erected a border-wall around the enclave, and introduced new migration policies branding many informal workers within its borders as a threat to Spanish society. Based on my preliminary months of research, this paper compares the Ceutan context with other research recently conducted on the topics of migration and borders in the Mediterranean region. It brings into focus key theoretical issues and assumptions that constantly emerge in such literature, particularly regarding the role of ‘a-cultural’ personal ties between migrants and locals in undermining State categories and ideology. This paper observes how the Ceutan case encourages us to expand our focuses and consequently problematise our understanding of crucial concepts such as ‘trust’ and ‘integration’

    Trust Games Measure Trust

    Get PDF
    The relationship between trust and risk is a topic of enduring interest. Although there are substantial differences between the ideas the terms express, many researchers from different disciplines have pointed out that these two concepts become very closely related in personal exchange contexts. This raises the important practical concern over whether behaviors in the widely-used “trust game†actually measure trust, or instead reveal more about risk attitudes. It is critical to confront this question rigorously, as data from these games are increasingly used to support conclusions from a wide variety of fields including macroeconomic development, social psychology and cultural anthropology. The aim of this paper is to provide cogent evidence on the relationship between trust and risk in “trust†games. Subjects in our experiment participate either in a trust game or in its risk game counterpart. In the trust version, subjects play a standard trust game and know their counterparts are human. In the risk version, subjects know their counterparts are computers making random decisions. We compare decisions between these treatments, and also correlate behavior with subjects’ risk attitudes as measured by the Holt and Laury (2002) risk instrument. We provide evidence that trusting behavior is different than behavior under risk. In particular, (i) decisions patterns in our trust and risk games are significantly different; and (ii) risk attitudes correlate with decisions in the risk game, but not the trust game.trust; risk attitudes; laboratory experiments

    Isle of Gigha Heritage Trust: an innovation history

    Get PDF
    The Isle of Gigha Heritage Trust is a company limited by guarantee with a charitable status, consisting of an elected board of directors to represent the Isle of Gigha residents. Since its inception, the Isle of Gigha Heritage Trust has created three subsidiary trading companies, which operate the island’s commercial activities (such as the running of three wind turbines). These provide the Trust with financial sustainability and fund regeneration on the island. The aims of the Trust in setting up Gigha Renewable Energy Limited were, firstly, to advance community ownership and development on the island; secondly, to promote the financial, social and environmental sustainability of the island; and thirdly, to generate profits to be recycled into other community projects on the island, including housing improvements and energy efficiency measures. This innovation history traces the development of the Isle of Gigha Heritage Trust from its inception (i.e. when the community bought their island from its laird in 2002) through to its development of a portfolio of renewable and energy efficiency projects

    We propose a formal model of trust informed by the Global Computing scenario and focusing on the aspects of trust formation, evolution, and propagation. The model is based on a novel notion of trust structures which, building on concepts from trust management and domain theory, feature at the same time a trust and an information partial order

    The process of building consumer trust in E-Commerce is based on the presence of trust features or trust attributes in the websites. Consumer may examine e-Commerce websites for the existence of trust attributes. However, to date, which trust attributes contribute to the website’s trustworthiness and which trust attributes give more value to consumer has not been adequately explored. Therefore, the purpose of the paper is to look for the relevant trust attributes for e-Commerce websites and to identify the importance ranking of trust attributes that contribute significantly to the trustworthiness of e-Commerce website. Various journal papers and articles related to e-Commerce field have been referred in order to identify the trust attributes. An online survey that received 1230 respondents was carried out to investigate the importance ranking of ten trust attributes. The paper contributes to the discussion on how to build trust in e-Commerc
