To eat or not to eat meat: that is the question

Meat is a well accepted food with appreciable appealing. Due to its high nutritional value it plays a central role in human development. Meat/meat derivates are important sources of proteins, minerals and vitamins. Their nutritional importance is paralleled to their economic impact. Paying attention to the social alarm originated by a recent publication of WHO about the relationship between red and/or processed meat consumption and cancer, this paper reviews the following aspects: a) the present consumption of meat/meat products in Spain; b) the contribution of their macro/micronutrients to the recommended dietary allowances; c) the obliged use of additives (e.g. nitrites and nitrates) to warrant the food safety, and their daily intake. In addition health risks derived from a high consumption, as well as the most appropriate culinary uses in order to reduce the formation of toxic products (e.g. N-nitrosocompounds) are commented. Due to the huge variety of available meat products, this paper concludes that any generalization should be avoided. We also emphasize about the advantages of consuming meat/meat products in the frame of a Mediterranean diet, rich in vegetables, fruits, and bioactive compounds.

The Strange Case of Eugenics: A Subject’s Ontogeny in a Long-Lived Classification Scheme and the Question of Collocative Integrity

Classification schemes are built at a particular point in time; at inception, they reflect a worldview indicative of that time. This is their strength, but results in potential weak- nesses as worldviews change. For example, if a scheme of mathematics is not updated even though the state of the art has changed, then it is not a very useful scheme to users for the purposes of information retrieval. However, change in schemes is a good thing. Changing allows designers of schemes to update their model and serves as a responsible mediator between resources and users. But change does come at a cost. In the print world, we revise universal clas- sification schemes—sometimes in drastic ways—and this means that over time, the power of a classification scheme to collocate is compromised if we do not account for scheme change in the organization of affected physical resources. If we understand this phenomenon in the print world, we can design ameliorations for the digital world.

Motivating Students to Learn English: Intrinsic and Extrinsic Strategies to Meet the Needs of First Time Learners

Motivation is the key to learning. The present study is about the relationship between intrinsic and extrinsic motivation as they affect learning with regard to students who are learning EFL for the first time. Cape Verdean seventh grade students learning English for the first time are generally very enthusiastic about the language before they start learning it in the high school. However, that enthusiasm seems not to be maintained throughout the school year and oftentimes teachers hear them complain about the difficulties of mastering aspects of the language. It seems that for some reason their motivation is undermined. Why does that happen? Is it the students’ fault or the teacher’s? If it the teacher’s fault, which motivation strategies work best to cope with this problem: intrinsic or extrinsic? With this in mind I asked the question: What is the relationship between students’ needs, interests, goals and expectations to learn English as a foreign language and teachers’ roles as facilitators and motivators? There are many studies that have been carried out in the field of motivation, and up to now, there seems to be no consensus of which is the best. For the purposes of this paper, three main theories will be discussed that have prevailed in the field of motivational psychology: the behavioural, the cognitive and the humanistic theories. Within these theories sub-theories are discussed and their relationship is explained with intrinsic and extrinsic motivation regarding Cape Verdean students learning English for the first time.

Implementing a question-generation strategy with bilingual students: exploring the perspectives of a beginning teacher /

This study examined the challenges associated with the explicit delivery of questiongeneration strategy with 8 Arab Canadian students from the perspective of a bilingual beginning teacher. This study took place in a private school and involved 2 stages consisting of 9 instructional sessions, and individual interviews with the students. Data gathered from these interviews and the researcher's field notes from the sessions were used to gain insights about the participants' understanding and use of explicit instruction. The themes that emerged from the data included "teacher attitude," "students' enhanced metacognitive awareness and strategy use," "listening skills," and "instructional challenges." Briefly, teacher's attitude demonstrated how teacher's beliefs and knowledge influenced her willingness and perseverance to teach explicitly. Students' enhanced metacognitive awareness and strategy use included students' understanding and use of the question-generation strategy. The students' listening skills suggested that culture may influence their response to the delivery of explicit instruction. Here, the cultural expectations associated with being a good listener reinforced students' willingness to engage in this strategy. Students' prior knowledge also influenced their interaction with the question-generation strategy. Time for process versus covering content was a dominant instructional challenge. This study provides first hand information for teachers when considering how students' cultural backgrounds may affect their reactions to explicit strategy instruction.

The Money Question and the Good Life

This paper proposes a theory of the good life for use in answering the question how much money the rich should spend on fighting poverty. The paper moves from the abstract to the concrete. To begin with, it investigates various ways to get an answer to the question what is good, and finds itself drawn to objective theories of the good. It then develops, taking Bernard Williams and Martha Nussbaum as its guides, a broad outline of a theory of the good. It holds that something evil happens to people if they do not have a real choice from a reasonable number of projects that realize most of their key capacities to a certain degree, and in connection to this it points to the great importance of money. The paper goes on specifically to consider what criticisms of Nussbaum's version of the capability approach are implied in this outline of a theory of the good. Next, it gets more specific and asks how much money the rich can give -and how they can be restricted in spending their money- without suffering any evil. It does three suggestions: the tithe suggestion, the ecological (or footprint) suggestion, and the fair trade suggestion. To conclude, the paper returns to the question how much money the rich should spend on fighting poverty.

Environmental education and the health risk question: how do we educate the educators working with this theme?

Our society is presently seeing a trend of continuous increase of risk with severe consequences, especially those linked to environmental aspects. It has obligated us to reflect on this production and its effects, either positive or negative, and, after a long reflection, to think about the adopted model of civilization and the possibilities of changing such a model. The educational institution is among the social departments responsible for this revision process, since it represents one possibility to promote a more critical vision from society, providing it with tools needed for a more responsible action. However, schools are dominated by a traditional work, which does not allow for enough and proper attention to these relevant and current questions, and which involve a critical analysis of the conceptions and values established by our civilization, resulting in the present patterns of science-technology-society relations and their influence on the environment and health. Several research works have indicated a diversity of barriers that obstruct this necessary change. Since formal education plays an important role in the education of society for this theme, in this paper the possibilities and difficulty dealing with this problem are discussed, focusing on the question of teacher education, based on investigations related to teacher education programs for environmental education. The data collected show the urgency for introducing this theme in teacher training programs, taking into account the fact that educators have their own conceptions, values and attitudes that should be considered in these programs.

The Rueter-Hess Dam and Reservoir Project: A Question of Sustainable Water

Water in sufficient quantities throughout the Colorado Front Range is becoming increasingly limited. This paper examines the consequences for continued unsustainable use of water for communities of the Denver metropolitan area. This paper also looks at the effect that water law in the West has for otherwise optimum distributions of water. In addition, four regional and state water studies are reviewed for their contribution to sustainable water. Finally, the Final Environmental Impact Statement of the Rueter-Hess dam and reservoir project in Parker, Colorado is explored. Key findings conclude that the Rueter-Hess project may not, by itself, provide sustainable water for Parker; but the project will create incentive and opportunity for communities throughout the region to address the question of sustainable water.

The Catholic Question in Contemporary Portuguese Civil Society: A Case of Muted Vibrancy? CES Papers - Open Forum #14, 2012

The ‘Catholic question’ in contemporary Portugal obliges us to consider whether Catholicism will remain a force in Portuguese associational life in the next century, or whether it faces a future of slow and steady decline. On the one hand, an overall statistical drop of church membership, and the lack of religious practice by almost half of self-identified Roman Catholics, suggests that the future of the Catholic Church in Portugal will probably be very different than the past. On the other hand, the church’s support for democratic processes, the important social services it provides, and its educational establishment, have certainly been a positive factor in Portuguese associational life, and helped the larger process of democratic-regime consolidation since the Carnation Revolution of 1974. This paper suggests that social scientists need to move beyond the lens normally applied to the question of Catholicism in contemporary Europe (i.e. it is a dying, anti-modern, anti-rational, conservative institution), and instead consider the complex interplay of its demographic challenges combined with the popular sources of its theological and spiritual strength, as well as its vital societal contributions, to assess whether or not it will remain a force in Portuguese associational life in the future.

Evaluating the additionality of public sector assistance to Irish firms: a question of ownership?

This article presents an innovative approach to estimating the additionality of financial assistance awarded to firms by an Irish regional development agency. The 'self assessment approach' is used to derive estimates of deadweight and displacement for firms in the Shannon region of Ireland. Irish studies have derived high estimates of deadweight by international standards. In light of this, and the fact that successive Irish governments have placed emphasis on Foreign Direct Investment as an engine for growth, the primary objective here is to address the question of whether the type of firm ownership matters with respect to resulting deadweight and/or displacement estimates. The latter question is addressed using logistic regression analysis to test whether, ceteris paribus, firm ownership is a key-determining factor for estimates of deadweight and/or displacement. The results show that ownership does not matter in the case of deadweight, but regarding displacement there are differences between indigenous and foreign-owned firms albeit at very low levels. More precisely, as expected, indigenously owned firms are more likely to lead to higher estimates of displacement.

The role of musical aptitude in the pronunciation of English vowels among Polish learners of English

It has long been held that people who have musical training or talent acquire L2 pronunciation more successfully than those that do not. Indeed, there have been empirical studies to support this hypothesis (Pastuszek-Lipińska 2003, Fonseca-Mora et al. 2011, Zatorre and Baum 2012). However, in many of such studies, musical abilities in subjects were mostly verified through questionnaires rather than tested in a reliable, empirical manner. Therefore, we run three different musical hearing tests, i.e. pitch perception test, musical memory test, and rhythm perception test (Mandell 2009) to measure the actual musical aptitude in our subjects. The main research question is whether a better musical ear correlates with a higher rate of acquisition of English vowels in Polish EFL learners. Our group consists of 40 Polish university students studying English as their major who learn the British pronunciation model during an intense pronunciation course. 10 male and 30 female subjects with mean age of 20.1 were recorded in a recording studio. The procedure comprised spontaneous conversations, reading passages and reading words in isolation. Vowel measurements were conducted in Praat in all three speech styles and several consonantal contexts. The assumption was that participants who performed better in musical tests would produce vowels that are closer to the Southern British English model. We plotted them onto vowel charts and calculated the Euclidean distances. Preliminary results show that there is potential correlation between specific aspects of musical hearing and different elements of pronunciation. The study is a longitudinal project and will encompass two more years, during which we will repeat the recording procedure twice to measure the participants’ progress in mastering the English pronunciation and comparing it with their musical aptitude.

The Southern Brazilian shelf: general characteristics, quaternary evolution and sediment distribution

Extending from latitude 34ºS to 22ºS the Southern Brazilian shelf constitutes the only part of the Brazilian shelf with a subtropical to temperate environment. The studies on the different geological aspects of the area began in the 1960's and have recently been reassessed after studies related to the determination of the Economic Exclusive Zone. In terms of morphology, the Southern Brazilian shelf may be divided into three sectors, the São Paulo Bight, the Florianópolis-Mostardas Sector and the Rio Grande Cone, characterized by conspicuous differences in terms of geological determining factors, bathymetry, declivities and the presence of canyons and channels. Despite the existence of hundreds of radiocarbon datings the sea level changes curve of southern Brazil during the Last Glacial Cycle is still a matter of debate. A recent controversy on the Middle and late Holocene sea level changes curve raised the question of the amplitude of the oscillations which occurred in the period. Also, a few but relatively consistent radiocarbon datings suggest the occurrence of a high sea level during Isotope Stage 3. In terms of sedimentary cover the Southern Brazilian shelf exhibits a very strong hydrodynamic control, both latitudinal and bathymetrical. The sector southward from 25ºS is characterized by the influence of the plume of water carrying sediments originating from the Río de La Plata. Actually its presence is conspicuous up to 28ºS, with the area between this latitude and 25ºS constituting a transitional zone. In terms of bathymetry the outer shelf is marked by the "floor-polisher" effect of the Brazil Current, which is responsible for the maintenance of a relict facies in areas deeper than 100 meters.

On the name of the lepidophagous characid fish Roeboexodon guyanensis (Puyo) (Teleostei: Characiformes: Characidae)

The arguments for the usage of the names Gnathoplax, Roeboexodon, R. geryi, and R. guyanensis are revised. Based on the literature and museum specimens, we recommend that the neotype of Exodon guyanensis should be considered valid; that the genus Gnathoplax should be considered an objective junior synonym of Roeboexodon; and that Roeboexodon geryi should be considered an objective junior synonym of Exodonguyanensis.

Can we make a Bohmian electron reach the speed of light, at least for one instant?

In Bohmian mechanics, a version of quantum mechanics that ascribes world lines to electrons, we can meaningfully ask about an electron's instantaneous speed relative to a given inertial frame. Interestingly, according to the relativistic version of Bohmian mechanics using the Dirac equation, a massive particle's speed is less than or equal to the speed of light, but not necessarily less. That is, there are situations in which the particle actually reaches the speed of light-a very nonclassical behavior. That leads us to the question of whether such situations can be arranged experimentally. We prove a theorem, Theorem 5, implying that for generic initial wave functions the probability that the particle ever reaches the speed of light, even if at only one point in time, is zero. We conclude that the answer to the question is no. Since a trajectory reaches the speed of light whenever the quantum probability current (psi) over bar gamma(mu)psi is a lightlike 4-vector, our analysis concerns the current vector field of a generic wave function and may thus be of interest also independently of Bohmian mechanics. The fact that the current is never spacelike has been used to argue against the possibility of faster-than-light tunneling through a barrier, a somewhat similar question. Theorem 5, as well as a more general version provided by Theorem 6, are also interesting in their own right. They concern a certain property of a function psi : R(4) -> C(4) that is crucial to the question of reaching the speed of light, namely being transverse to a certain submanifold of C(4) along a given compact subset of space-time. While it follows from the known transversality theorem of differential topology that this property is generic among smooth functions psi : R(4) -> C(4), Theorem 5 asserts that it is also generic among smooth solutions of the Dirac equation.
