Over the past decades, many studies have dealt with Anglicisms in Spanish, not only in science and technology, but also in other areas such as business, fashion and even sports. However, in spite of the large number of works on Spanish Anglicisms in sports, these have often disregarded the distinction between Anglicisms and false Anglicisms. Given their importance as evidence of the particular relationships between languages, this article focuses on the use of false Anglicisms in the Spanish language of sports, which has not only adopted English words giving them new meanings and usage, but has also either imported items with an English appearance from other languages or created its own forms based on English patterns. Although these false Anglicisms, which have proven extremely popular in various European languages (not only Spanish), have frequently been used and disseminated, as some examples will prove, little attention has been paid to their differences with the English term or their non-English origin.

The overall purpose of this collected papers dissertation was to examine the utility of a cognitive apprenticeship-based instructional coaching (CAIC) model for improving the science teaching efficacy beliefs (STEB) of preservice and inservice elementary teachers. Many of these teachers perceive science as a difficult subject and feel inadequately prepared to teach it. However, teacher efficacy beliefs have been noted as the strongest indicator of teacher quality, the variable most highly correlated with student achievement outcomes. The literature is scarce on strong, evidence-based theoretical models for improving STEB.^ This dissertation is comprised of two studies. STUDY #1 was a sequential explanatory mixed-methods study investigating the impact of a reformed CAIC elementary science methods course on the STEB of 26 preservice teachers. Data were collected using the Science Teaching Efficacy Belief Instrument (STEBI-B) and from six post-course interviews. A statistically significant increase in STEB was observed in the quantitative strand. The qualitative data suggested that the preservice teachers perceived all of the CAIC methods as influential, but the significance of each method depended on their unique needs and abilities. ^ STUDY #2 was a participatory action research case study exploring the utility of a CAIC professional development program for improving the STEB of five Bahamian inservice teachers and their competency in implementing an inquiry-based curriculum. Data were collected from pre- and post-interviews and two focus group interviews. Overall, the inservice teachers perceived the intervention as highly effective. The scaffolding and coaching were the CAIC methods portrayed as most influential in developing their STEB, highlighting the importance of interpersonal relationship aspects in successful instructional coaching programs. The teachers also described the CAIC approach as integral in supporting their learning to implement the new inquiry-based curriculum. ^ The overall findings hold important implications for science education reform, including its potential to influence how preservice teacher training and inservice teacher professional development in science are perceived and implemented. Additionally, given the noteworthy results obtained over the relatively short durations, CAIC interventions may also provide an effective means of achieving improvements in preservice and inservice teachers’ STEB more expeditiously than traditional approaches.^

In recent years, there has been an enormous growth of location-aware devices, such as GPS embedded cell phones, mobile sensors and radio-frequency identification tags. The age of combining sensing, processing and communication in one device, gives rise to a vast number of applications leading to endless possibilities and a realization of mobile Wireless Sensor Network (mWSN) applications. As computing, sensing and communication become more ubiquitous, trajectory privacy becomes a critical piece of information and an important factor for commercial success. While on the move, sensor nodes continuously transmit data streams of sensed values and spatiotemporal information, known as ``trajectory information". If adversaries can intercept this information, they can monitor the trajectory path and capture the location of the source node. This research stems from the recognition that the wide applicability of mWSNs will remain elusive unless a trajectory privacy preservation mechanism is developed. The outcome seeks to lay a firm foundation in the field of trajectory privacy preservation in mWSNs against external and internal trajectory privacy attacks. First, to prevent external attacks, we particularly investigated a context-based trajectory privacy-aware routing protocol to prevent the eavesdropping attack. Traditional shortest-path oriented routing algorithms give adversaries the possibility to locate the target node in a certain area. We designed the novel privacy-aware routing phase and utilized the trajectory dissimilarity between mobile nodes to mislead adversaries about the location where the message started its journey. Second, to detect internal attacks, we developed a software-based attestation solution to detect compromised nodes. We created the dynamic attestation node chain among neighboring nodes to examine the memory checksum of suspicious nodes. The computation time for memory traversal had been improved compared to the previous work. Finally, we revisited the trust issue in trajectory privacy preservation mechanism designs. We used Bayesian game theory to model and analyze cooperative, selfish and malicious nodes' behaviors in trajectory privacy preservation activities.

The evolution of knowledge and technology in recent decades has brought profound changes in science policy, not only in the countries but also in the supranational organizations. It has been necessary, therefore, to adapt the scientific institutions to new models in order to achieve a greater and better communication between them and the political counterparts responsible for defining the general framework of relations between science and society. The Federationon of Scientific Societies of Spain (COSCE, Confederación de Sociedades Científicas de España) was founded in October 2003 to respond to the urgent need to interact with the political institutions and foster a better orientation in the process of making decisions about the science policy. Currently COSCE consists of over 70 Spanish scientific societies and more than 40,000 scientists. During its twelve years of active life, COSCE has developed an intense work of awareness of the real situation of science in Spain by launching several initiatives (some of which have joined other organizations) or by joining initiatives proposed from other groups related to science both at the Spanish level and at the European and non-European scenarios.

Suggesting that the political diversity of American science fiction during the 1960s and early 1970s constitutes a response to the dominance of social liberalism throughout the 1940s and 1950s, I argue in Making the Men of Tomorrow that the development of new hegemonic masculinities in science fiction is a consequence of political speculation. Focusing on four representative and influential texts from the 1960s and early 1970s, Philip K. Dick’s The Three Stigmata of Palmer Eldritch and Ubik, Robert A. Heinlein’s The Moon Is a Harsh Mistress, and Ursula K. Le Guin’s The Dispossessed, this thesis explores the relationship between different conceptions of hegemonic masculinity and three separate but related political ideologies: the social ethic, market libertarianism, and socialist libertarianism. In the first two chapters in which I discuss Dick’s novels, I argue that Dick interrogates organizational masculinity as part of a larger project that suggests the inevitable infeasibility of both the social ethic and its predecessor, social liberalism. In the next chapter, I shift my attention to Heinlein’s The Moon Is a Harsh Mistress as a way of showing how, unlike Dick, other authors of the 1960s and early 1970s sought to move beyond social liberalism by imagining how new political ideologies, in this case market libertarianism, might change the way men see themselves. Having demonstrated how the libertarian potential of Heinlein’s novel is ultimately undermined by its insistent and uncompromising biological determinism, I then discuss how Le Guin’s The Dispossessed uses the socialist libertarianism of the moon Anarres to suggest a more egalitarian form of masculinity, one that makes possible, to some extent at least, a future in which men might embrace not only the mutual aid of socialism, but also the primacy of individual rights that is at the heart of all forms of libertarianism and liberalism.

How does an archaeological museum understand its function in a digital environment? Consumer expectations are rapidly shifting, from what used to be a passive relationship with exhibition contents, towards a different one, in which interaction, individuality and proactivity define the visitor experience. This consumer paradigm is much studied in fast moving markets, where it provokes immediately measurable impacts. In other fields, such as tourism and regional development, the very heterogeneous nature of the product to be branded makes it near to impossible for only one player to engage successfully. This systemic feature implies that museums, acting as major stakeholders, often anchor a regional brand around which SME tend to cluster, and thus assume responsibilities in constructing marketable identities. As such, the archaeological element becomes a very useful trademark. On the other hand, it also emerges erratically on the Internet, in personal blogs, commercial websites, and social networks. This forces museums to enter as a mediator, authenticating contents and providing credibility. What might be called the digital pull factor poses specific challenges to museum management: what is to be promoted, and how, in order to create and maintain a coherent presence in social media? The underlying issue this paper tries to address is how museums perceive their current and future role in digital communication.
