A Systematic Framework of Experiential Learning: Challenging Educators to Make College more than an Aggregation of Credits  [PDF]
Alana Dillette, Lori Sipe
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.99106
Abstract: This article examines experiential learning within the context of leader development in a hospitality and tourism management program. First, we present findings about high impact experiences from student blogs (n = 60) and discuss key themes within the context of Kolb’s four phases of experiential learning. This is followed by a discussion about how these findings influence the systematic redesign of our core leadership curriculum. Findings suggest strong consideration be given to providing contexts for authentic practice, encouraging exploration and personalization, mentoring both ways, and the value of integrated and well-timed facilitation. A four-year framework is presented detailing specific high impact experiences and outcomes aligned with a progression of leader development for undergraduates.

Abstract: the objective of this work was to evaluate the effects of boron rates on dry matter yield and root morphologic parameters of two varieties of upland rice. the experiment was carried out from april to july of 2004, in a greenhouse, in botucatu, s?o paulo state, with two varieties of rice, caiapó and brs talento. the seeds were germinated in a controlled chamber, and five days later, the plants were transplanted in plastic pots of 8 l, being supported by cleaned sand, being kept four plants per pot. the boron rates were 0.0; 0.5; 1.0; 2.0; 4.0 and 8.0 mg of b l-1, applied via nutrient solution. the harvest was accomplished 70 days after planting, being collected separately the shoot and root, and being determined their dry matter and n and b concentrations, as length, surface area and medium diameter of the roots. it was not able to get to the positive effects of boron application, evidencing that, for the rice cropping the optimum rate was lower than 0.5 ml l-1 of b. the application of 3.4 and 3.8 mg l-1 of b caused toxic effects to the caiapó and talento cvs., respectively. the toxic limit for the two cvs. roots is the 2.7 mg l-1 of b concentration. under several boron toxic, the plants of rice reduced drastically the length and increased the radicular diameter, resulting in a smaller absorption nutrients area.
Expression of PKC Iota Affects Neuronal Differentiation of PC12 Cells at Least Partly Independent of Kinase Function  [PDF]
Alana Doonachar, Alan R. Schoenfeld
CellBio (CellBio) , 2014, DOI: 10.4236/cellbio.2014.31001
Abstract: Atypical PKC (aPKC) plays a role in establishing cell polarity and has been indicated in neuronal differentiation and polarization, including neurite formation in rat pheochromocytoma PC12 cells, albeit by unclear mechanisms. Here, the role of the aPKC isoform, PKC iota (PKCι), in the early neuronal differentiation of PC12 cells, was investigated. NGF-treated PC12 cells with stably expressed exogenous wild-type PKCι showed decreased expression of a neuroendocrine marker, increased expression of a neuronal marker and increased neurite formation. Stable expression of a kinase-inactive PKCι, but not constitutively active PKCι lacking a regulatory domain, had similar though less potent effects. Pharmacological inhibition of endogenous aPKC kinase activity in parental PC12 cells did not inhibit neurite formation, suggesting that some of the observed effects of PKCι expression on neuronal differentiation are kinase-independent. Interestingly, exogenous expression of wild-type and kinase-inactive PKCι had little effect on overall PKCι activity, but caused a decrease in PKC zeta (PKCζ) kinase activity, suggesting an interplay between the two isoforms that may underlie the observed results. Overall, these findings suggest that in PC12 and perhaps other neuroendocrine precursor cells, PKCι influences an early differentiation decision between the neuroendocrine (chromaffin) and sympathetic neuron cell lineages, potentially by affecting PKCζ function.
Communicating the right to food sovereignty: The voice of the Campesino in the Global Campaign for Agrarian Reform
Alana Mann
PRism Online PR Journal , 2009,
Abstract: Historically, the ‘campesino’ or peasant farmer has been marginalised from the public sphere. This paper explores how La Via Campesina, the world’s largest independent social movement, has employed framing techniques to legitimise the claims of a diverse membership through its Global Campaign for Agrarian Reform. It is proposed that frame strategists within the movement are effectively challenging dominant paradigms of land reform by engaging in public relations activities, including relationship management, alliance-building and strategic repositioning within a broader network or ‘counterpublic’ of social justice organisations.
Spaces for Talk: Information and Communication Technologies (ICTs) and Genuine Dialogue in an International Advocacy Movement
Alana Mann
Asian Social Science , 2009, DOI: 10.5539/ass.v4n10p3
Abstract: Despite the digital divide that exists between the developed and developing world, communication technologies such as the Internet are providing new opportunities for transnational advocacy. This paper explores issues of identity and co-operation between actors participating in the Global Campaign for Agrarian Reform (GCAR), led by the peoples’ movement La Via Campesina, focusing on the application of Internet-based services. While the movement has successfully reframed the land reform debate within the global public sphere, and makes use of the World Wide Web in its role as a strategic bridge-builder within the Campaign, digital connectivity does not necessarily overcome challenges of participation and representation.
Una aproximación a la importancia de la elección lingüística en la configuración de la identidad hispánica en los Estados Unidos
Alana Jackson
Sintagma : Revista de Lingüística , 2007,
Abstract: In today's globalised world, advances in international travel and communication have led to higher rates of migration and intercultural contact. Therefore, communication between different groups sharing a space is of paramount importance. This article offers an insight into the link between culture and language in society, with a focus on multilingual groups, and, more specifically, Spanish-English bilingual groups who find themselves subject to generalisations and marginalisation by wider society. Theoretical investigation casts light on the inextricable link between language and identity, showing that Spanish-English bilingual groups use bilingualism, and in particular code-switching, as a means of differentiation from the dominant group. They also implement these same strategies to distinguish themselves from Spanish-speaking communities that they consider to be unlike themselves as a response to wider society's generalisation of all Spanish-speaking groups, usually under the term `latino'. Identities are fluid, and in many cases contain elements of different cultures. It is therefore important to take into account the different components, not just language, but also gender, ethnicity, and socioeconomic situation, and how these vary between groups.
Um estudo de possíveis correla??es entre representa??es docentes e o ensino de Ciências e Matemática para surdos
Borges, Fábio Alexandre;Costa, Luciano Gonsalves;
Ciência & Educa??o (Bauru) , 2010, DOI: 10.1590/S1516-73132010000300005
Abstract: throughout this paper, we have investigated some teachers' representations about issues related to the teaching of the deaf. teachers who have worked in such educational contexts in the cities of maringa and londrina were recorded while different topics were addressed such as: pre-service teaching education, training, sign language, interpreters, infrastructure, prejudice, science teaching, learning assessment, and others. for data analysis, we have used qualitative textual analysis. the expectation is that, through the teachers' representations, we can raise the discussion about this phenomenon: the teaching of mathematics and science to deaf students. five out ten teachers were categorized for the purposes of this paper. several issues were raised and all were worthy to be discussed in trying to find a way for a better education in science and mathematics for the deaf.
Generalized space and linear momentum operators in quantum mechanics
Bruno G. da Costa,Ernesto P. Borges
Physics , 2013, DOI: 10.1063/1.4884299
Abstract: We propose a modification of a recently introduced generalized translation operator, by including a $q$-exponential factor, which implies in the definition of a Hermitian deformed linear momentum operator $\hat{p}_q$, and its canonically conjugate deformed position operator $\hat{x}_q$. A canonical transformation leads the Hamiltonian of a position-dependent mass particle to another Hamiltonian of a particle with constant mass in a conservative force field of a deformed phase space. The equation of motion for the classical phase space may be expressed in terms of the generalized dual $q$-derivative. A position-dependent mass confined in an infinite square potential well is shown as an instance. Uncertainty and correspondence principles are analyzed.
