Different strategies for improving summer thermal comfort in heavyweight traditional buildings

In order to exploit the passive energy potential of the building envelope, it is important to provide a right combination of insulation thickness, heat capacity and night-time ventilation. In this paper, this issue will be tackled with reference to an historic building in Catania (Southern Italy). The building was built at the end of the XIX century, and its opaque envelope is entirely made with lava stones, which is typical of traditional architecture in this area. Starting from the current configuration of the building, many hypotheses for refurbishment are considered, combined with different strategies for passive cooling, such as night-time ventilation, use of shading devices and adoption of highly-reflective coatings. The effectiveness of each solution in terms of summer thermal comfort is evaluated through dynamic thermal simulations carried out with EnergyPlus. The results show the synergic effect of these strategies, as well as their individual impact, and allow to draw some general conclusions about the behaviour of heavyweight buildings under moderately hot weather conditions.

Global, local, or regional? The locus of MNE strategies

This paper provides an overview of the main insights arising from the ‘regional strategy’ literature. It also develops the contours of a new, rich research agenda for future international strategy scholarship, whereby the region should be introduced as an explicit, third geographic level of analysis, in addition to the country-level and the global level. Regional strategy analysis requires a fundamental rethink of mainstream theories in the international strategy sphere. This rethink involves, inter alia, internalization theory, with its resource-based view and transaction cost economics components, as well as the integration (I) – national responsiveness (NR) framework.

Flipped classroom and learning strategies

This paper seeks to answer the research question "How does the flipped classroom affect students’ learning strategies?" In e-learning research, several studies have focused on how students and teachers perceive the flipped classroom approach. In general, these studies have reported pleasing results. Nonetheless, few, if any, studies have attempted to find out the potential effects of the flipped classroom approach on how students learn. This study was based on two cases: 1) a business modelling course and 2) a research methodology course. In both cases, participating students were from information systems courses at Dalarna University in Sweden. Recorded lectures replaced regular lectures. The recorded lectures were followed by seminars that focused on the learning content of each lecture in various ways. Three weeks after the final seminar, we arranged for two focus group interviews to take place in each course, with 8 to 10 students participating in each group. We asked open questions on how the students thought they had been affected and more dedicated questions that were generated from a literature study on the effects of flipped classroom courses. These questions dealt with issues about mobility, the potential for repeating lectures, formative feedback, the role of seminars, responsibility, empowerment, lectures before seminars, and any problems encountered. Our results show that, in general, students thought differently about learning after the courses in relation to more traditional approaches, especially regarding the need to be more active. Most students enjoyed the mobility aspect and the accessibility of recorded lectures, although a few claimed it demanded a more disciplined attitude. Most students also expressed a feeling of increased activity and responsibility when participating in seminars. Some even felt empowered because they could influence seminar content. The length of and possibility to navigate in recorded lectures was also considered important. The arrangement of the seminar rooms should promote face-to-face discussions. Finally, the types of questions and tasks were found to affect the outcomes of the seminars. The overall conclusion with regard to students’ learning strategies is that to be an active, responsible, empowered, and critical student you have to be an informed student with possibilities and mandate to influence how, where and when to learn and be able to receive continuous feedback during the learning process. Flipped classroom can support such learning.

Comprehension strategies of above average English as a foreign language (EFL) readers

The study reported in this thesis is a single-shot case study, which aims to provide a detailed description ofthe reading comprehension strategies used by fifteen student teachers ofEnglish from Indonesian- and Javanese-speaking backgrounds in the last year of their four-year Strata-One study at a university In Yogyakarta, Indonesia. These readers were above average among their peers in that their average indexes of grades in Reading and Speaking classes were 3.22 and 3,34 respectively, while the average indexes ofthe peer group were 271 and 2.63, respectively, out ofa scale of 0 to 400. In addition, while students in this university may complete their study by course work or by research, these readers were all enrolled as research students. As studying comprehension strategies involves complex issues, a multi-method approach is required, not only for breadth of coverage, but also to allow for a check on the validity of individual methods. To achieve the goal of the study, thinka1oud tasks, retellings, a reading comprehensIon test, indepth interviews and observations were employed to explore the strategies used. An analysis of the recorded data indicates that these readers used thirty strategies classified under five clusters: infomiation gathering, information processing, text interpretation, comprehension monitoring, and comprehension utilisation. In general, readers started gathering information by silent reading, interpreted the text by an inference or a paraphrase, and ended the task by making selfreflections relevant to the text. Most readers managed to identify problems when they occurred, and monitored their comprehension when they doubted their interpretation, as could be seen from their rereading the text or vocalising its pail(s). When direct interpretation was difficult, readers associated the text with prior knowledge or interrelated parts of the text, The readers in this study share characteristics of both poor and good native readers, in the sense that there was evidence ofgood strategy use butthe readers did not manage to maintain it consistently. As a result, even the successful readers were not able to maximise their potential. The implication is that in order to develop students into independent readers, strategy instruction should be part of and appropriately embedded in, the reading instruction. There is a need not merely to teach strategies as such, but rather to teach flexibility in strategy use. While there was sufficient evidence that thinkaloud tasks and their complementary methods worked to achieve the goals ofthe present study, similar studies with different cohorts are suggested for crosschecks.

Web-text : perceptions of digital reading skills in the ESL classroom

New strategies required in Web reading and digital writing cause previous notions of literacy to be reshaped and compel teachers to rethink classroom reading practice. The aim of this paper is to compare student perceptions of reading skills needed in the traditional print- text mode with the skills needed to read and gather information on the Web. Do students perceive reading as different on the Web? Are there implications for reading classroom teachers? This research was conducted in a medium-sized suburban government primary school of 580 students from 72 different countries. The participants were 48 students in two grade-six classes, with a focus on 12 English as second language (ESL) students' responses. These students came from Taiwan, China, India, Malaysia, Poland and Bhutan. The study was replicated in an adult ELICOS language centre environment with the authors own class of 18 students from China, Indonesia, Korea, Taiwan, Thailand and Japan. Different student expectations of Web-text compared to paper-text were evident. This research adds to our constantly evolving notions of literacy embracing technology and can be applied to primary, secondary and tertiary levels of ESL teaching practice.

Reading, writing, crafting – Innovations in first year tertiary writing pedagogy

This paper will outline some of the rationale behind, and strategies contributing to, curriculum revision in first-year creative writing at Deakin University in 2012 – delivered in that year and currently running in 2013. The process aimed to produce two consecutive offerings, with distinct but strategically scaffolded preoccupations. This paper deals with the first of these. The design process for this offering, named ‘Writing Craft’, involved addressing two central concerns: (a) the need to unhook the initial encounter with tertiary creative writing pedagogy from a preoccupation with ‘genres’ or the ‘forms’ of creative writing (such as prose fiction, creative nonfiction, script, poetry, and so on) and instead to reorient efforts towards establishing an engagement with craft per se; (b) to address a perceived impoverishment in the range of texts to which students had been exposed prior to commencing study – in other words, to emphasise the practice of reading to facilitate the practice of writing. The curriculum design also involved reimagining assessment, noting the ‘messages about making’ sent to students via the framing of tasks and rubrics. Aiming instead to deemphasise the role of inspiration and ‘work arriving fully formed’, it sought to offer assessment that provided clear – and bounded – prompts for incidents of making and the practice of craft, as well as to provoke conversation with a broad range of texts as a way of courting intertextual inspiration and aesthetic formation.

Patient engagement strategies used for hypertension and their influence on self-management attributes

Background. Several effective methods to facilitate patient self-management of hypertension are available in primary care. These include direct support from community pharmacists and general practice, and the use of home blood pressure (BP) monitoring. The aim of this study is to establish the prevalence of use of key strategies and to determine their independent relationship with patient self-management attributes.

Methods. A survey of patients with treated hypertension was undertaken in 27 community pharmacies. This established recent use of BP monitoring and advice from health professionals. Patient awareness of BP and targets, appropriateness of BP targets and adherence to anti-hypertensive medications were assessed as indicative self-management outcomes. Predictors of outcomes were determined using binary logistic regression.

Results. Overall, 215 surveys were returned. Two-thirds of patients were aged >65 years, and 45% had conditions warranting tighter BP control (<130/80 mmHg). Almost all patients reported monitoring of their BP in the previous year and 63% could report their most recent BP reading. Just 36% reported knowing a target BP, and 78% of reported targets were within guidelines recommendations. One-fifth (22%) monitored their own BP, and 15% reported non-adherence to medication. Doctors provided the large majority of professional advice. Self-monitoring or documentation of BP readings was independently associated with increased likelihood of BP and target BP being known.

Conclusions. Regular monitoring of BP does not automatically translate to professional advice. Increased uptake of patient self-monitoring should be promoted as a means of enabling self-management.

Focus group discussions of literacy assessment and world wide web-based reading intervention

Focus groups provide a means for participants in research to take on a greater role in the evaluation of the research and planning of its various stages. The role and outcomes of focus groups conducted with participants in a World Wide Web Project in literacy assessment and intervention are reported. Thirteen individuals with severe communication impairments participated in one of three focus groups. The groups were held after an assesment of reading skills and a trial period of intervention as part of the Web Project. The aim of the focus groups was to obtain feedback from participants about their involvement in the project and to discuss strategies for the next stage of the intervention. The focus groups offered a forum for participants to talk about what they did and did not like about the assessment and trial intervention. The discussions provided information about issues of both a practical and emotional nature that might have otherwise been unavailable to the researchers. Brainstorming of strategies provided valuable input for the next stage of the project and involved both the researchers and participants in a form of participatory action research.

Effectiveness, costs, and cost-effectiveness of recruitment strategies for a mammographic screening program to detect breast cancer

BACKGROUND AND PURPOSE: Since effective and affordable recruitment methods are essential for the widespread implementation of mammographic screening for detection of breast cancer, we studied the effectiveness, the costs, and the cost-effectiveness of various recruitment strategies in the population targeted by a pilot Australian program that offered free mammography screening between 1988 and 1990. METHODS: We evaluated three public recruitment strategies--local newspaper articles, community promotion, and promotion to physicians--and five personal strategies--invitation letters with or without specified appointment times, either alone or with a follow-up letter, or telephone call to nonattenders. The effectiveness of public recruitment strategies was estimated from monthly attendance rates by Poisson regression analysis, while the probability of attendance in response to personal strategies was calculated using logistic regression analysis. Costs were determined by resource usage studies. The cost-effectiveness ratios for personal strategies were determined using decision analysis. RESULTS: The costs in 1988-1989 Australian dollars per woman recruited were $22 for local newspaper articles and $106 for community promotion. No detectable increase in attendance resulted from promotion to physicians. When the cost of reserving an appointment was considered, the most cost-effective personal recruitment strategy was an invitation letter without a specified appointment time, followed by a second letter to nonattenders. This strategy recruited 35.6% of women in the sample targeted and cost $10.52 per attendee. In comparison, the most effective personal recruitment strategy was a letter with a specified appointment time followed by a second letter to nonattenders, which recruited 44.1% of women at an average cost of $19.99 and a marginal cost of $59.71 per additional attendee. CONCLUSIONS: Personal recruitment strategies were more cost-effective than public strategies. The most cost-effective personal strategy was an invitation letter without a specified appointment time, followed by a second letter to nonattenders.

Library Privacy Policies in 2015: Strategies for Renewed Relevance

In recent decades, library associations have advocated for the adoption of privacy and confidentiality policies as practical support to the Library Code of Ethics with a threefold purpose to (1) define and uphold privacy practices within the library, (2) convey privacy practices to patrons and, (3) protect against potential liability and public relations problems. The adoption of such policies has been instrumental in providing libraries with effective responses to surveillance initiatives such as warrantless requests and the USA PATRIOT ACT. Nevertheless, as reflected in recent news stories, the rapid emergence of data brokerage relationships and technologies and the increasing need for libraries to utilize third party vendor services have increased opportunities for data surveillers to access patrons’ personal information and reading habits, which are funneled and made available through multiple online library service platforms. Additionally, the advice that libraries should “contract for the same level of privacy reflected in their privacy policies” is no longer realistic given that the existence of multiple vendor contracts negotiated at arms length is likely to produce varying privacy terms and even varying definitions of what constitutes personal information (PII). These conditions sharply threaten the effectiveness and relevance of library privacy policies and privacy initiatives in that such policies increasingly offer false comfort by failing to reflect privacy weaknesses in the data sharing landscape and vendor contracts when library-vendor contracts fail to keep up with vendor data sharing capabilities. While some argue that library privacy ethics are antiquated and rendered obscure in the current online sharing economy PEW studies point to pronounced public discomfort with increasing privacy erosion. At the same time, new directions in FTC enforcement raise the possibility that public institutions’ privacy policies may serve as swords to unfair or deceptive commercial trade practices – offering the potential of renewed relevance for library privacy and confidentiality policies. This dual coin of public concern and the potential for enhanced FTC enforcement suggests that when crafting privacy polices libraries must now walk the knife’s edge by offering patrons both realistic notice about the limitations of protections the library can ensure while at the same time publicly holding vendors accountable to library privacy ethics and expectations. Potential solutions for how to walk this edge are developed and offered as a subject for further discussion to assist the modification of model policies for both public and academic libraries alike.

Annual Report of Nebraska's Reading First

Thi report summarizes the results of the first year of the Reading First Initiative in Nebraska. Results show that teachers and schools have made a real effort to change. Student performance in the earlier grades has shown great promise for the following years, however, growth in fluency and comprehension in grades 2 and 3 were not as impressive and require additional attention. Overall, students make at least a year’s progress in most schools and most demographic groups. Schools can make much better use of the data they were collecting and need further direction in this area The assessment results were triangulated by observations in the classrooms, interviews, and teacher responses to professional development- teachers know how to teach PA and the alphabetic principle but were still struggling with: finding time and effective strategies for fluency training teaching comprehension strategies teaching self monitoring. Growing gaps for SPED, Ethnic minorities, and ELL students suggest an emphasis on the secondary and tertiary levels of intervention in the schools.

Seeing beyond reading: a survey on visual text analytics

We review recent visualization techniques aimed at supporting tasks that require the analysis of text documents, from approaches targeted at visually summarizing the relevant content of a single document to those aimed at assisting exploratory investigation of whole collections of documents.Techniques are organized considering their target input materialeither single texts or collections of textsand their focus, which may be at displaying content, emphasizing relevant relationships, highlighting the temporal evolution of a document or collection, or helping users to handle results from a query posed to a search engine.We describe the approaches adopted by distinct techniques and briefly review the strategies they employ to obtain meaningful text models, discuss how they extract the information required to produce representative visualizations, the tasks they intend to support and the interaction issues involved, and strengths and limitations. Finally, we show a summary of techniques, highlighting their goals and distinguishing characteristics. We also briefly discuss some open problems and research directions in the fields of visual text mining and text analytics.

New enhancement strategies for plasmon-enhanced fluorescence biosensors

This thesis investigates metallic nanostructures exhibiting surface plasmon resonance for the amplification of fluorescence signal in sandwich immunoassays. In this approach, an analyte is captured by an antibody immobilized on a plasmonic structure and detected by a subsequently bound fluorophore labeled detection antibody. The highly confined field of surface plasmons originates from collective charge oscillations which are associated with high electromagnetic field enhancements at the metal surface and allow for greatly increased fluorescence signal from the attached fluorophores. This feature allows for improving the signal-to-noise ratio in fluorescence measurements and thus advancing the sensitivity of the sensor platform. In particular, the thesis presents two plasmonic nanostructures that amplify fluorescence signal in devices that rely on epifluorescence geometry, in which the fluorophore absorbs and emits light from the same direction perpendicular to the substrate surface.rnThe first is a crossed relief gold grating that supports propagating surface plasmon polaritons (SPPs) and second, gold nanoparticles embedded in refractive index symmetric environment exhibiting collective localized surface plasmons (cLSPs). Finite-difference time-domain simulations are performed in order to design structures for the optimum amplification of established Cy5 and Alexa Fluor 647 fluorophore labels with the absorption and emission wavelengths in the red region of spectrum. The design takes into account combined effect of surface plasmon-enhanced excitation rate, directional surface plasmon-driven emission and modified quantum yield for characteristic distances in immunoassays. Homebuilt optical instruments are developed for the experimental observation of the surface plasmon mode spectrum, measurements of the angular distribution of surface plasmon-coupled fluorescence light and a setup mimicking commercial fluorescence reading systems in epifluorescence geometry.rnCrossed relief grating structures are prepared by interference lithography and multiple copies are made by UV nanoimprint lithography. The fabricated crossed diffraction gratings were utilized for sandwich immunoassay-based detection of the clinically relevant inflammation marker interleukin 6 (IL-6). The enhancement factor of the crossed grating reached EF=100 when compared to a flat gold substrate. This result is comparable to the highest reported enhancements to date, for fluorophores with relatively high intrinsic quantum yield. The measured enhancement factor excellently agrees with the predictions of the simulations and the mechanisms of the enhancement are explained in detail. Main contributions were the high electric field intensity enhancement (30-fold increase) and the directional fluorescence emission at (4-fold increase) compared to a flat gold substrate.rnCollective localized surface plasmons (cLSPs) hold potential for even stronger fluorescence enhancement of EF=1000, due to higher electric field intensity confinement. cLSPs are established by diffractive coupling of the localized surface plasmon resonance (LSPR) of metallic nanoparticles and result in a narrow resonance. Due to the narrow resonance, it is hard to overlap the cLSPs mode with the absorption and emission bands of the used fluorophore, simultaneously. Therefore, a novel two resonance structure that supports SPP and cLSP modes was proposed. It consists of a 2D array of cylindrical gold nanoparticles above a low refractive index polymer and a silver film. A structure that supports the proposed SPP and cLSP modes was prepared by employing laser interference lithography and the measured mode spectrum was compared to simulation results.rn

Three Strategies for Promoting Intellectual Engagement in Advanced Undergraduate Seminars

With the humanities increasingly contested, we must adopt pedagogical approaches that promote the integral role of humanistic inquiry in student academic achievement. Whether they explore the eighteenth-century novel, cultural artifacts of the Third Republic, or sociopolitical controversies in contemporary literature, the three models described in this article propose innovative learning strategies for advanced undergraduate French and Francophone Studies seminars that fulfill the humanistic goals of the American university. From directed close reading exercises to analysis of the historical archive to creative exploratory writing, these activities engage students intellectually with complex cultural and narrative materials from diverse traditions and periods.
