The dependence of contrail formation on the weather pattern and altitude in the North Atlantic

Aircraft flying through cold ice-supersaturated air produce persistent contrails which contribute to the climate impact of aviation. Here, we demonstrate the importance of the weather situation, together with the route and altitude of the aircraft through this, on estimating contrail coverage. The results have implications for determining the climate impact of contrails as well as potential mitigation strategies. Twenty-one years of re-analysis data are used to produce a climatological assessment of conditions favorable for persistent contrail formation between 200 and 300 hPa over the north Atlantic in winter. The seasonal-mean frequency of cold ice-supersaturated regions is highest near 300 hPa, and decreases with altitude. The frequency of occurrence of ice-supersaturated regions varies with large-scale weather pattern; the most common locations are over Greenland, on the southern side of the jet stream and around the northern edge of high pressure ridges. Assuming aircraft take a great circle route, as opposed to a more realistic time-optimal route, is likely to lead to an error in the estimated contrail coverage, which can exceed 50% for westbound north Atlantic flights. The probability of contrail formation can increase or decrease with height, depending on the weather pattern, indicating that the generic suggestion that flying higher leads to fewer contrails is not robust.

Can we predict when “dying” will be difficult?: Progressive achievements in L2 English

A large body of research has focused on the observation that second language (L2) learners are limited in their production of temporal and aspectual forms. For example, in L2 English, it has been shown learners use progressive marking with activity verbs and only rarely extend the form to telic verb phrases such as accomplishments or achievements (Bardovi-Harlig and Reynolds, 1995; Bardovi-Harlig, 2000; Robison, 1995). Shirai and Andersen (1995) proposed that activities represent the prototype for the category of progressive aspect and learners generally acquire the prototype first. However, very little research has focused explicitly on advanced learners to see if they eventually extend beyond the prototype. In addition, properties of the native language have not systematically been taken into account. Achievements such as "die" are especially interesting in that they interact differently with markers of progressive aspect across languages. The present study investigated the acquisition of progressive achievements in English by native speakers of Chinese and Korean in order to examine whether there is evidence of universal difficulty, as would be predicted by the prototype account, or whether similarity between the L1 and L2 (as in the case of English and Korean) can facilitate acquisition, as would be predicted by transfer. Our results suggest that the properties of the native language play an important role, supporting the transfer account. However, neither L1 group performs at the level of native speakers. We argue that the acquisition of aspect is influenced by both the properties of the native language and the semantic and pragmatic complexity of the target computation.

Introducing "ecoputation": a universal systems design process

A universal systems design process is specified, tested in a case study and evaluated. It links English narratives to numbers using a categorical language framework with mathematical mappings taking the place of conjunctions and numbers. The framework is a ring of English narrative words between 1 (option) and 360 (capital); beyond 360 the ring cycles again to 1. English narratives are shown to correspond to the field of fractional numbers. The process can enable the development, presentation and communication of complex narrative policy information among communities of any scale, on a software implementation known as the "ecoputer". The information is more accessible and comprehensive than that in conventional decision support, because: (1) it is expressed in narrative language; and (2) the narratives are expressed as compounds of words within the framework. Hence option generation is made more effective than in conventional decision support processes including Multiple Criteria Decision Analysis, Life Cycle Assessment and Cost-Benefit Analysis.The case study is of a participatory workshop in UK bioenergy project objectives and criteria, at which attributes were elicited in environmental, economic and social systems. From the attributes, the framework was used to derive consequences at a range of levels of precision; these are compared with the project objectives and criteria as set out in the Case for Support. The design process is to be supported by a social information manipulation, storage and retrieval system for numeric and verbal narratives attached to the "ecoputer". The "ecoputer" will have an integrated verbal and numeric operating system. Novel design source code language will assist the development of narrative policy. The utility of the program, including in the transition to sustainable development and in applications at both community micro-scale and policy macro-scale, is discussed from public, stakeholder, corporate, Governmental and regulatory perspectives.

Abilities and Cultural Understanding through Literature in the EFL Classroom : - A Literature Review

The English language can be seen as a lingua franca of contemporary times. Its spread and use in the globalized world has affected most levels of society and it can be argued that, in current times, English is synonymous with communication. This need for communication has shaped the English as a Foreign Language (EFL) syllabus, which is evident in the Swedish national steering documents for the educational system. For the upper secondary school these documents show an emphasis on communication, on cultural understanding, and also on the use of literature within the EFL classroom. The need to possess communicative abilities and cultural understanding, in connection with the use of literature, has sparked an interest to investigate if and how literature itself can be used as a tool to develop and improve EFL students’ communicative skills and cultural understanding. This literature review thesis analyzes five international research articles from different geographical parts of the Globe. The findings are categorized, compared, synthesized, and finally discussed in order to answer the research questions asked, and also compared with the English subject syllabus for the Swedish upper secondary school. The findings indicate that the analyzed articles share a consensus, to a varied degree, regarding the positive aspects of literature use in the EFL setting. The arguments are that communicative skills and cultural understanding are intertwined - enabling each other to exist, develop, and improve. One cannot exist fully without the other, and literature is a good tool to use to develop and improve these abilities. Literature can help develop all skills needed to acquire and produce both written and spoken English, and it also enables cultural understanding and a broadening of the mind. Where the articles differ somewhat is in the ideas of why literature is a good tool, how to implement literature in the classrooms, and what some of the negative aspects might be. The thesis also brings the lack of Swedish studies within EFL to the readers’ attention, as well as the need to do more research focusing on the students’ perspectives towards literature use in the EFL setting.

The impact of communications and understanding on the success of business/IT alignment

This article reports on an investigation of IS stakeholders communication and mutual understanding, and their impact on the success of business / IT alignment. In particular, by following a hermeneutic study of transcripts of two focus groups and several interviews conducted with senior business and IT executives, the paper explores the issues of modern business context and practices, project scope and structure, trust, language and nomenclature, and the barriers to the effective stakeholder communication and  understanding. The study results are finally compared against the standard model of business and IT alignment. The main unexpected finding being executives' pre-occupation with issues of "marginal" value to the alignment model, such as day-to-day management of communicative and understanding effectiveness, as opposed to the fundamental issues of strategy and infrastructure fit.

The development of knowledge about language in teacher training: what works?

Efforts have been made over many years by applied linguists in a number of English-speaking countries to raise awareness of language across the primary and secondary school curriculum, with varying degrees of success (see Denham & Lobeck, 2010). Many of these countries are sites of mass migration from non-English speaking countries, creating linguistic equity issues. In Australia, the new National Curriculum mandates that teachers of all disciplines will be required to provide pedagogy responsive to the language learning needs of English as an Additional Language (EAL) students. However, policy documents do not specify how this goal should be realized, and teachers and researchers are engaged in constant debate about what views of language could inform teacher training (e.g. structural and/or functional). This paper reports on a project which aimed to identify 1) the views of teacher educators on language in the curriculum, and 2) the language-related challenges faced by teachers in training. The current paper focuses on the language awareness of trainee teachers. Ten education students were interviewed about their understandings and experiences of language and language learning. It was found that many students experienced lack of confidence and knowledge about language (KAL), but that awareness of sociocultural elements of language provided them with ways to connect with a broader understanding of language issues. Results were analyzed from the perspective of sociocultural theory and will have implications for teacher training in any educational context where students are learning an additional language in order to integrate into a national schooling system.

Programa de capacitação de famílias de crianças, jovens e adultos usuários de comunicação alternativa

This study aimed to enter a training program for family members of children, youth and adults who use augmentative and alternative communication systems in the context of alternative languages . The study included families in the age group of 25-65 years in the period 2010- 2012. The activities were held weekly with duration of one hour in a alternative communication laboratory. All activities were videotaped and after that, the verbal participants’ reports were transcribed. The obtained categories were analyzed according to the steps of the program. The results indicated that families realized: the necessity of graphics systems for communication; the importance of adapted materials; and the need to understand their children’s different skills. The study reinforced the need for systematic and continuous guidance for families, as well as highlighted the use of graphics systems in the context of language.

Adapting health-risk communication to the specific cultural contexts of diverse populations : an assessment of malaria-treatment programs in Liberia

Drawing on theories of technical communication, rhetoric, literacy, language and culture, and medical anthropology, this dissertation explores how local culture and traditions can be incorporated into health-risk-communication-program design and implementation, including the design and dissemination of health-risk messages. In a modern world with increasing global economic partnerships, mounting health and environmental risks, and cross-cultural collaborations, those who interact with people of different cultures have “a moral obligation to take those cultures seriously, including their social organization and values” (Hahn and Inhorn 10). Paradoxically, at the same time as we must carefully adapt health, safety, and environmental-risk messages to diverse cultures and populations, we must also recognize the increasing extent to which we are all becoming part of one, vast, interrelated global village. This, too, has a significant impact on the ways in which healthcare plans should be designed, communicated, and implemented. Because communicating across diverse cultures requires a system for “bridging the gap between individual differences and negotiating individual realities” (Kim and Gudykunst 50), both administrators and beneficiaries of malaria-treatment-and-control programs (MTCPs) in Liberia were targeted to participate in this study. A total of 105 people participated in this study: 21 MTCP administrators (including designers and implementers) completed survey questionnaires on program design, implementation, and outcomes; and 84 MTCP beneficiaries (e.g., traditional leaders and young adults) were interviewed about their knowledge of malaria and methods for communicating health risks in their tribe or culture. All participants showed a tremendous sense of courage, commitment, resilience, and pragmatism, especially in light of the fact that many of them live and work under dire socioeconomic conditions (e.g., no electricity and poor communication networks). Although many MTCP beneficiaries interviewed for this study had bed nets in their homes, a majority (46.34 percent) used a combination of traditional herbal medicine and Western medicine to treat malaria. MTCP administrators who participated in this study rated the impacts of their programs on reducing malaria in Liberia as moderately successful (61.90 percent) or greatly successful (38.10 percent), and they offered a variety of insights on what they might do differently in the future to incorporate local culture and traditions into program design and implementation. Participating MTCP administrators and beneficiaries differed in their understanding of what “cultural incorporation” meant, but they agreed that using local indigenous languages to communicate health-risk messages was essential for effective health-risk communication. They also suggested that understanding the literacy practices and linguistic cultures of the local people is essential to communicating health risks across diverse cultures and populations.

Linguistic relativity and dialectical idiomatization: language ideologies and second language acquisition in the Irish language revival of Northern Ireland

A considerable number of Irish Catholics in West Belfast, originally native English speakers, have started learning the Irish language throughout the Northern Irish conflict in order to feel more Irish. Many of these have developed a strong conviction that the Irish language contains a different worldview from the one embodied in English. However, rather than constituting a plausible representation of relevant differences embodied in the languages themselves, this article puts forward the hypothesis that such a neo-Whorfian endorsement of linguistic relativity might rather be the product of dialectical idiomatization, following from the interplay of prevailing language ideologies and effects of second language acquisition.

Trypanosoma brucei RRM1 is a nuclear RNA-binding protein and modulator of chromatin structure

TbRRM1 of Trypanosoma brucei is a nucleoprotein that was previously identified in a search for splicing factors in T. brucei. We show that TbRRM1 associates with mRNAs and with the auxiliary splicing factor polypyrimidine tract-binding protein 2, but not with components of the core spliceosome. TbRRM1 also interacts with several retrotransposon hot spot (RHS) proteins and histones. RNA immunoprecipitation of a tagged form of TbRRM1 from procyclic (insect) form trypanosomes identified ca. 1,500 transcripts that were enriched and 3,000 transcripts that were underrepresented compared to cellular mRNA. Enriched transcripts encoded RNA-binding proteins, including TbRRM1 itself, several RHS transcripts, mRNAs with long coding regions, and a high proportion of stage-regulated mRNAs that are more highly expressed in bloodstream forms. Transcripts encoding ribosomal proteins, other factors involved in translation, and procyclic-specific transcripts were underrepresented. Knockdown of TbRRM1 by RNA interference caused widespread changes in mRNA abundance, but these changes did not correlate with the binding of the protein to transcripts, and most splice sites were unchanged, negating a general role for TbRRM1 in splice site selection. When changes in mRNA abundance were mapped across the genome, regions with many downregulated mRNAs were identified. Two regions were analyzed by chromatin immunoprecipitation, both of which exhibited increases in nucleosome occupancy upon TbRRM1 depletion. In addition, subjecting cells to heat shock resulted in translocation of TbRRM1 to the cytoplasm and compaction of chromatin, consistent with a second role for TbRRM1 in modulating chromatin structure. IMPORTANCE: Trypanosoma brucei, the parasite that causes human sleeping sickness, is transmitted by tsetse flies. The parasite progresses through different life cycle stages in its two hosts, altering its pattern of gene expression in the process. In trypanosomes, protein-coding genes are organized as polycistronic units that are processed into monocistronic mRNAs. Since genes in the same unit can be regulated independently of each other, it is believed that gene regulation is essentially posttranscriptional. In this study, we investigated the role of a nuclear RNA-binding protein, TbRRM1, in the insect stage of the parasite. We found that TbRRM1 binds nuclear mRNAs and also affects chromatin status. Reduction of nuclear TbRRM1 by RNA interference or heat shock resulted in chromatin compaction. We propose that TbRRM1 regulates RNA polymerase II-driven gene expression both cotranscriptionally, by facilitating transcription and efficient splicing, and posttranscriptionally, via its interaction with nuclear mRNAs.
