Full Text Available This paper describes the effect of reading strategy instruction on Second Language (L2 students’ reading comprehension in a Botswana College of Education. The intervention programme was implemented based on the observation that some trainee teachers failed to improve on their L2 proficiency after spending a year in the L2 classroom. Prior to the intervention, difficulty in reading and comprehending had been identified as one of the contributing factors to their failure to improve on their proficiency level. A reading comprehension test was used to collect data from participants who were trainee teachers at a College of Education in Botswana before and after the intervention. The six-week intervention programme focused on seven reading strategies, namely the use of background knowledge, self-questioning, inferencing, rereading, drawing conclusions, identifying main ideas and summarising. The findings suggest that strategy training can increase L2 students’ reading comprehension. Based on the findings, it is recommended that strategy training be introduced into the L2 syllabus of the primary school teacher trainees in all Botswana Colleges of Education.

Full Text Available Web-based education is facing a paradigm shift under the rapid development of information and communication technology. The new paradigm of learning requires special techniques of course design, special instructional models, and special methods of evaluation. This paper investigates the effectiveness of an adaptive instructional strategy for teaching and learning through the Web and blended learning environments. The central theme of this strategy is that instructional strategies give instructors and students a conceptual as well as a practical mode of delivery from which to teach and learn. Considering and applying new instructional strategy can help instructors to understand the uses of pedagogical content knowledge, as well as to reflect the role of technological content knowledge that can be adapted and/or adopted in teaching in all educational levels and environments. The main objective of this paper was to develop a holonomic instructional strategy for Web-based and blended learning. This strategy is guided by the non-linear and interactive features of learning environments. The strategy is consisted of four dimensions: designing, developing, delving and distributing. In this new instructional strategy, learning is holonomic and adaptive. Learning occurs in an open learning environment, in which instructors are designing a shared vision, developing a sharable e-learning task, delving students’ learning through scaffolding and salvaging students’ knowledge. The expected outcome of this instructional strategy is that each learner will develop a cognitive schema to be used to organize and construct knowledge and meaning in similar context of learning which may increase the generalizability, trustworthiness and transferability of learning. The results of applying this new strategy showed that this strategy is effective on developing both achievement and deep learning levels among a sample of graduate students.

Full Text Available Students today expect the use of technology in their classes, rather than have to listen to less-than-engaging lectures. College students are connected electronically and incessant technology consumers. As a result, they may prefer the infusion of technologies to help them learn and enjoy the process of learning, rather than having to listen exclusively to lectures. To investigate this, the authors solicited student perceptions to assess the importance of learning through technology-nested instructional strategies. Student perceptions give direction to and affirm the benefits of instructional strategies that increase student motivation to engage more actively in their learning. Based on quantitative and qualitative responses through action research in multiple courses, students perceive their learning as more engaging and enjoyable when technology-nested instructional strategies are infused into their classes.

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] The lack of knowledge about how to effectively spread and sustain the use of research-based instructional strategies is currently a significant barrier to the improvement of undergraduate physics education. In this paper we address this lack of knowledge by reporting on an interview study of 35 physics faculty, of varying institution types, who were self-reported users of, former users of, or knowledgeable nonusers of the research-based instructional strategy Peer Instruction. Interview questions included in this analysis focused on the faculty's experiences, knowledge, and use of Peer Instruction, along with general questions about current and past teaching methods used by the interviewee. The primary findings include the following: (i) Faculty self-reported user status is an unreliable measure of their actual practice. (ii) Faculty generally modify specific instructional strategies and may modify out essential components. (iii) Faculty are often unaware of the essential features of an instructional strategy they claim to know about or use. (iv) Informal social interactions provide a significant communication channel in the dissemination process, in contrast to the formal avenues of workshops, papers, websites, etc., often promoted by change agents, and (v) experience with research-based strategies as a graduate student or through curriculum development work may be highly impactful. These findings indicate that educational transformation can be better facilitated by improving communication with faculty, supporting effective modification by faculty during implementation, and acknowledging and understanding the large impact of informal social interactions as a mode of dissemination.

The mechanism linking instruction in scientific topics and instruction in logical reasoning strategies is not well understood. This study assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching adolescent students about blood pressure problems. Logical reasoning instruction for this study emphasizes the controlling-variables strategy. Science topic instruction emphasizes variables affecting blood pressure. Subjects receiving logical reasoning instruction link their knowledge of blood pressure variables to their knowledge of controlling variables more effectively than those receiving science topic instruction alone - their specific responses show how they attempt to integrate their understanding.Received: 15 April 1988

Full Text Available Comprehension is a critical part of the reading process, and yet learners continue to struggle with it and teachers continue to neglect it in their teaching. Many reasons exist for the lack of focus on reading comprehension instruction, but for the most part, teachers simply do not seem to view comprehension as part of the reading process, are not able to teach the concept, and are seemingly not taught to do so during their teacher training years. In addition to this, comprehension continues to be viewed as part of 'language teaching', and is therefore viewed as the so-called 'language teacher's' domain. In support of effective comprehension instruction in the unique, multilingual South African education environment, this article proposes a framework for reading strategy instruction, aimed specifically at teachers. The framework was developed from a research study, and refined through subsequent application in a university course as well as a further study. The framework acknowledges that reading is a multifaceted and complex process, and accordingly, provides sufficient structure for teachers. It further addresses the issue of comprehension instruction through the use of selected reading strategies, designed to be applied by all teachers in all subjects in a flexible and easy manner.

Full Text Available Investigating the efficiencies and deficiencies of reading strategies is one of the noticeable issues in the related theory and research in reading comprehension instruction. This study was to examine the impact of Directed Reading Thinking Activity (DRTA and Guided Reading (GR on reading comprehension. Sixty three Iranian students of grade one in Shahed high school in the city of Bojnourd took part in the study. They were assigned in three groups, one control and two experimental groups. The instruction lasted for ten weeks. This study utilized a pretest posttest control group in quantitative quasi- experimental design. The same reading comprehension test was administered as pre-test and post-test. The results were twofold: First, the instruction of learning strategies could foster reading comprehension skill. Second, while the explicit instruction of both strategies could improve the students' reading comprehension skill, Directed Reading Thinking Activity had a more significant positive effect than Guided Reading.

Two experiments investigated the effects of strategy knowledge and strategy training on the working memory (WM) performance in children (ages 10-11) with and without reading disabilities (RD). Experiment 1 examined the relationship between strategy knowledge (stability of strategy choices) and WM performance as a function of initial, gain (cued), and maintenance conditions. WM performance was significantly improved for both groups under cued conditions; however, the performances of children with RD were inferior to those of children without RD across all memory conditions. Measures of WM capacity rather than strategy stability or processing efficiency best predicted reading comprehension performance. Experiment 2 assessed the effects of strategy training on WM performance by randomly assigning children to strategy instruction or control conditions. Significant improvements in WM performance occurred as a function of training conditions, but the residual WM differences between the reading groups remained. Although the results showed that stable strategy choices, cued performance, and strategy instruction significantly bolstered WM performance in children with RD, their overall WM performance, however, was constrained by capacity limitations.

We aimed to investigate upper elementary children's strategy use in the domain of multidigit division in two instructional settings: the Netherlands and Flanders (Belgium). A cross-sectional sample of 119 Dutch and 122 Flemish fourth to sixth graders solved a varied set of multidigit division problems. With latent class analysis, three distinct strategy profiles were identified: children consistently using number-based strategies, children combining the use of column-based and number-based strategies, and children combining the use of digit-based and number-based strategies. The relation between children's strategy profiles and their instructional setting (country) and grade were generally in line with instructional differences, but large individual differences remained. Furthermore, Dutch children more frequently made adaptive strategy choices and realistic solutions than their Flemish peers. These results complement and refine previous findings on children's strategy use in relation to mathematics instruction. Statement of contribution What is already known? Mathematics education reform emphasizes variety, adaptivity, and insight in arithmetic strategies. Countries have different instructional trajectories for multidigit division. Mixed results on the impact of instruction on children's strategy use in multidigit division. What does this study add? Latent class analysis identified three meaningful strategy profiles in children from grades 4-6. These strategy profiles substantially differed between children. Dutch and Flemish children's strategy use is related to their instructional trajectory. © 2017 The Authors.

In longitudinal studies, measurement invariance is required to conduct substantive comparisons over time or across groups. In this study, we examined measurement invariance on a recently developed instrument capturing student preferences for seven instructional strategies related to science learning and career interest. We have labeled these seven instructional strategies as Collaborating, Competing, Caretaking, Creating/Making, Discovering, Performing, and Teaching. A better understanding of student preferences for particular instructional strategies can help educators, researchers, and policy makers deliberately tailor programmatic instructional structure to increase student persistence in the STEM pipeline. However, simply confirming the relationship between student preferences for science instructional strategies and their future career choices at a single time point is not sufficient to clarify our understanding of the relationship between instructional strategies and student persistence in the STEM pipeline, especially since preferences for instructional strategies are understood to vary over time. As such, we sought to develop a measure that invariantly captures student preference over a period of time: the Framework for Observing and Categorizing Instructional Strategies (FOCIS). We administered the FOCIS instrument over four semesters over two middle school grades to 1009 6th graders and 1021 7th graders and confirmed the longitudinal invariance of the FOCIS measure. This confirmation of longitudinal invariance will allow researchers to examine the relationship between student preference for certain instructional strategies and student persistence in the STEM pipeline.

The purpose of the study was to compare virtual microscopy with light microscopy to determine differences in learning outcomes and learner attitudes in teaching clinical microscopy to physician assistant (PA) students. A prospective, randomized, crossover design study was conducted with a convenience sample of 67 first-year PA students randomized to 2 groups. One group used light microscopes to find microscopic structures, whereas the other group used instructor-directed video streaming of microscopic elements. At the midpoint of the study, the groups switched instructional strategies. Learning outcomes were assessed via posttest after each section of the study, with comparison of final practical examination results to previous cohorts. Attitudes about the 2 educational strategies were assessed through a postcourse questionnaire with a Likert scale. Analysis of the first posttest demonstrated that students in the video-streamed group had significantly better learning outcomes than those in the light microscopy group (P = .004; Cohen's d = 0.74). Analysis of the posttest after crossover showed no differences between the 2 groups (P = .48). Between the 2 posttests, students first assigned to the light microscopy group scored a 6.6 mean point increase (±10.4 SD; p = .0011), whereas students first assigned to the virtual microscopy group scored a 1.3 mean point increase (±7.1 SD; p = .29). The light microscopy group improved more than the virtual microscopy group (P = .019). Analysis of practical examination data revealed higher scores for the study group compared with 5 previous cohorts of first-year students (P virtual microscopy to traditional light microscopy.

Whether older adults can compensate for their associative memory deficit by using memory strategies efficiently might depend on their general cognitive abilities. This study examined the moderating role of an IQ estimate on the beneficial effects of strategy instructions. A total of 142 participants (aged 18-85 years) received either intentional learning or strategy ("sentence generation") instructions during encoding of word pairs. Whereas young adults with a lower IQ benefited from strategy instructions, those with a higher IQ did not, presumably because they already use strategies spontaneously. Older adults showed the opposite effect: following strategy instructions, older adults with a higher IQ showed a strong increase in memory performance (approximately achieving the level of younger adults), whereas older adults with a lower IQ did not, suggesting that they have difficulties implementing the provided strategies. These results highlight the importance of the role of IQ in compensating for the aging-related memory decline.

Full Text Available Strategy instruction is useful in teaching contexts. This paper examines the effects of strategy instruction in an EFL reading comprehension course carried out with 26 undergraduate students at a Colombian university. As a research method, a case study was implemented. There were three instruments with which to collect data: reading comprehension tests, teacher's field notes and self-reflection in class at the strategy instruction phase, and a learning perception questionnaire. Given that students improved in reading comprehension, it would seem that reading strategy instruction is indeed very useful. Also, it was noted that when students applied reading strategies, they became more self-confident and this in turn enhanced their motivation. Finally, when students applied the reading strategy approach, the use of dictionaries decreased considerably.

Each of the Active Learning strategies employed to teach Reactor Physics material has been or promises to be instructionally successful. The Cooperative Group strategy has demonstrated a statistically significant increase in student performance on the unit exam in teaching conceptually difficult, transport and diffusion theory material. However, this result was achieved at the expense of a modest increase in class time. The Tutorial CBI programs have enabled learning equally as well as classroom lectures without the direct intervention of an instructor. Thus, the Tutorials have been successful as homework assignments, releasing classroom time for other instruction. However, the time required for development of these tools was large, on the order of two hundred hours per hour of instruction. The initial introduction of the Case-Based strategy was roughly as effective as the traditional classroom instruction. Case-Based learning could well, after important modifications, perform better than traditional instruction. A larger percentage of the students prefer active learning strategies than prefer traditional lecture presentations. Student preferences for the active strategies were particularly strong when they believed that the strategies helped them learn the material better than they would have by using a lecture format. In some cases, students also preferred the active strategies because they were different from traditional instruction, a change of pace. Some students preferred lectures to CBI instruction, primarily because the CBI did not afford them the opportunity to question the instructor during the presentation

Full Text Available Underperformance of students in EAP reading comprehension has been an issue of concern for teachers, syllabus designers, and curriculum developers in general and for EAP practitioners in particular. In spite of the fact that considerable efforts have been made to improve reading comprehension of students through strategies instruction over past decades, EAP students however have not benefited much from learning strategies. Thus, this study intended to investigate the impact of a Strategies-Based Instruction (SBI on undergraduate students’ reading strategy use in an EAP context. Taking an instructional model from strategies taxonomy of Oxford (1990; 2001, it was assumed that in contrast to conventional EAP reading methods, SBI would be more effective in encouraging reading strategy use and as a result developing reading comprehension of EAP students through encouraging the use of effective strategies and skills. To do so, 80 freshman undergraduate students were chosen as the participants of this study who were in two intact classes. After administration of a pre-test, treatment (22 sessions, 2 sessions per week, and a post-test, the collected data was analyzed using t-test to examine the effect of the proposed method of instruction. The results of the analysis showed that the teaching intervention had a significant effect on students’ reading strategy use. The findings have implications for teachers encouraging effective reading comprehension instruction through the use of strategies in EAP teaching contexts.

This study examined how instructional challenges presented by gifted students shaped teachers’ instructional strategies. This study is a qualitative research grounded in a social constructivist framework. The participants were three high school science teachers who were teaching identified gifted students in both heterogeneously- and homogeneously-grouped classrooms. Major data sources are classroom observations and interviews. Data analysis indicated that these science teachers developed content-specific teaching strategies based on their understanding of gifted students, including: (a) instructional differentiation, e.g., thematic units, (b) variety in instructional mode and/or students’ products, (c) student grouping strategies and peer tutoring, (d) individualized support, (e) strategies to manage challenging questions, (f) strategies to deal with the perfectionism, and (g) psychologically safe classroom environments.

The purpose of this proposed research study was to identify actual teaching practices/instructional strategies for online science courses. The identification of these teaching practices/instructional strategies could be used to compile a set of teaching practices/instructional strategies for virtual high school and online academy science instructors. This study could assist online science instructors by determining which teaching practices/instructional strategies were preferred for the online teaching environment. The literature reviewed the role of online and face-to-face instructional strategies, then discussed and elaborated on the science instructional strategies used by teachers, specifically at the secondary level. The current literature did not reflect an integration of these areas of study. Therefore, the connectedness of these two types of instructional strategies and the creation of a set of preferred instructional practices for online science instruction was deemed necessary. For the purpose of this study, the researcher designed a survey for face-to-face and online teachers to identify preferred teaching practices, instructional strategies, and types of technology used when teaching high school science students. The survey also requested demographic data information from the faculty members, including years of experience, subject(s) taught, and whether the teacher taught in a traditional classroom or online, to determine if any of those elements affect differences in faculty perceptions with regard to the questions under investigation. The findings from the current study added to the literature by demonstrating the differences and the similarities that exist between online and face-to-face instruction. Both forms of instruction tend to rely on student-centered approaches to teaching. There were many skills that were similar in that both types of instructors tend to focus on implementing the scientific method. The primary difference is the use of

Full Text Available The exponential development of information technology has presented many opportunities to organizations; however, it has also presented several challenges. A key challenge is how do organizations effectively use information technology and incorporate it into their strategies to make full use of its capabilities as an enabler. The fast-changing nature of information technology has resulted in little empirical evidence on how it influences organization strategy. The Strategic Alignment Model was a popular model created to assist organizations to align their information technology and their business strategy; however, the growth of technology may have made this model irrelevant in this age. Therefore, organizations need to determine what factors drive this alignment. Using hermeneutic phenomenology, 12 in-depth interviews were conducted within IBM South Africa to determine real-life drivers that help create this alignment. The themes derived from the interview texts reveal that consumers are becoming more empowered; therefore, organizations need to be more flexible in their business models and strategies. Furthermore, the integration of cross-functional roles in the organization at the management level allow for improved alignment between information technology and strategy as better integrated roles bring a combination of these two elements.

The Geoscience Affective Research Network (GARNET) quantified the relationship between classroom teaching styles, student learning, and students’ motivations and attitudes for 14 different instructors at 2 community colleges, a private college, and 4 large public universities. Instruction was characterized with the Reformed Teaching Observation Protocol (RTOP). The 0-100 scale reflects the span between traditional instructor-centered lecture and interactive, student-centered courses. Every participating instructor was observed at least twice. Student learning was measured using a 15-question concept inventory (CI) focused on geologic time and plate tectonics. Twelve questions were from the Geologic Concept Inventory of Libarkin and Anderson (2005) and 3 questions were added on relative time. Students’ affective domain was measured using the Motivated Strategies for Learning Questionnaire (MSLQ), 81 questions that define 15 motivation and cognitive subcategories. 1152 students completed both surveys in the 2nd and 14th weeks of their class during the 2008-2010 academic years. RTOP scores ranged from 19 to 87. Learning gains ranged from 18.6% to 47.4% with students learning significantly more from instructors with higher RTOP scores. Learning gains and RTOP positively covary (R2 = 0.67). Adjusting for questions on which students scored high prior to instruction (>90% correct), results in an even stronger relationship (R2 = 0.89). Higher RTOP scores correlate to significant declines in many aspects of student motivation (extrinsic and intrinsic goals, task value, control of learning, and effort regulation). Declines occur mainly in lower and/or middle performing students as measured by grades. The highest performing students only show declines with respect to their control of learning beliefs. Students’ self-efficacy also declines with increasing use of student-student interactions. Higher RTOP scores only exhibit positive correlations to a few aspects of

Although negative attitudes toward science are common among women and men in undergraduate introductory science classes, women's attitudes toward science tend to be more negative than men's. The reasons for women's negative attitudes toward science include lack of self-confidence, fear of association with social outcasts, lack of women role models in science, and the fundamental differences between traditional scientific and feminist values. Attitudes are psychological constructs theorized to be composed of emotional, cognitive, and behavioral components. Attitudes serve functions, including social expressive, value expressive, utilitarian, and defensive functions, for the people who hold them. To change attitudes, the new attitudes must serve the same function as the old one, and all three components must be treated. Instructional designers can create instructional environments to effect attitude change. In designing instruction to improve women's attitudes toward science, instructional designers should (a) address the emotions that are associated with existing attitudes, (b) involve credible, attractive women role models, and (c) address the functions of the existing attitudes. Two experimental instructional modules were developed based on these recommendations, and two control modules were developed that were not based on these recommendations. The asynchronous, web-based modules were administered to 281 undergraduate geology and chemistry students at two universities. Attitude assessment revealed that attitudes toward scientists improved significantly more in the experimental group, although there was no significant difference in overall attitudes toward science. Women's attitudes improved significantly more than men's in both the experimental and control groups. Students whose attitudes changed wrote significantly more in journaling activities associated with the modules. Qualitative analysis of journals revealed that the guidelines worked exactly as predicted

Full Text Available Nanotechnology is a rapidly emerging technology dealing with so-called nanomaterials which at least in one dimension have size smaller than 100 nm. One of the most potentially promising applications of nanotechnology is in the area of tissue engineering, including biofabrication of 3D human tissues and organs. This paper focused on demonstrating how nanomaterials with nanolevel size can contribute to development of 3D human tissues and organs which have macrolevel organization. Specific nanomaterials such as nanofibers and nanoparticles are discussed in the context of their application for biofabricating 3D human tissues and organs. Several examples of novel tissue and organ biofabrication technologies based on using novel nanomaterials are presented and their recent limitations are analyzed. A robotic device for fabrication of compliant composite electrospun vascular graft is described. The concept of self-assembling magnetic tissue spheroids as an intermediate structure between nano- and macrolevel organization and building blocks for biofabrication of complex 3D human tissues and organs is introduced. The design of in vivo robotic bioprinter based on this concept and magnetic levitation of tissue spheroids labeled with magnetic nanoparticles is presented. The challenges and future prospects of applying nanomaterials and nanotechnological strategies in organ biofabrication are outlined.

Six sequences in the development of hypothesis-testing conceptions are proposed, involving (a) interpretation of the hypothesis; (b) the distinction between using theories and testing theories; (c) the consideration of multiple possibilities; (d) the relation of theory and data; (e) the nature of verification and falsification; and (f) the relation of truth and falsity. An alternative account is then provided involving three global stages: concrete operations, formal operations, and a postformal metaconstructivestage. Relative advantages and difficulties of the stage and sequence conceptualizations are discussed. Finally, three families of teaching strategy are distinguished, which emphasize, respectively: (a) social transmission of knowledge; (b) carefully sequenced empirical experience by the student; and (c) self-regulated cognitive activity of the student. It is argued on the basis of Piaget's theory that the last of these plays a crucial role in the construction of such logical reasoning strategies as those involved in testing hypotheses.

This study examined the extent to which science teachers in Academic Year Governor's Schools were adhering to the national standards for suggested science instruction and providing an appropriate learning environment for gifted learners. The study asked 13 directors, 54 instructors of advanced science courses, and 1190 students of advanced science courses in 13 Academic Year Governor's Schools in Virginia to respond to researcher-developed surveys and to participate in classroom observations. The surveys and classroom observations collected demographic data as well as instructors' and students' perceptions of the use of various instructional strategies related to national science reform and gifted education recommendations. Chi-square analyses were used to ascertain significant differences between instructors' and students' perceptions. Findings indicated that instructors of advanced science classes in secondary schools for the gifted are implementing nationally recognized gifted education and science education instructional strategies with less frequency than desired. Both students and instructors concur that these strategies are being implemented in the classroom setting, and both concur as to the frequency with which the implementation occurs. There was no significant difference between instructors' and students' perceptions of the frequency of implementation of instructional strategies. Unfortunately, there was not a single strategy that students and teachers felt was being implemented on a weekly or daily basis across 90% of the sampled classrooms. Staff development in gifted education was found to be minimal as an ongoing practice. While this study offers some insights into the frequency of strategy usage, the study needs more classroom observations to support findings; an area of needed future research. While this study was conducted at the secondary level, research into instructional practices at the middle school and elementary school gifted science

Full Text Available This study investigated the influence of Pre-question and genre-based instructional strategies on science undergraduates’ achievement in, and attitude to, reading. Using purposive sampling,two specialised universities in Nigeria were selected and stratified sampling was employed in assigning students to research groups based on gender and performance in a verbal ability test. Two hundred and eighty-five students participated in the study. Pre-post randomised block experimental design was used with three experimental groups and one control group. The experimental procedure involving Pre-question, genre-based instruction and a combination of Pre-question and genre-based instructional strategies were used for the experimental groups for four weeks whilst the control group received normal teacher input. Data were collected through a Reading Comprehension Achievement Test and Students’ Attitude Questionnaire. Qualitative data, obtained from videotapes of classroom interactions, were subjected to conversation and interaction analyses and quantitative data were analysed with Analysis of Covariance (ANCOVA. The results indicate that although there was no significant main effect of instructional strategy on students’ achievement in reading comprehension, there was significant main effect of instructional strategy on students’ attitude to reading (F(3,231 = 30.9;p <.05. Findings from the qualitative enquiry revealed that female students were more voluble and assertive in their responses probably because of the need to resist male domination whilst male students used discourse strategies to affirm their authority. The study indicated that the combination of pre-question and genre-based approach was the most effective in enhancing the students’ attitude to reading. Reading is one of the most useful of the Language Arts skills which learners need for academic reasons and for lifelong learning. The globalised world demands that the second language
Full Text Available In the face of higher costs of operation and increasing pressures from customers for better service, the logistics organization must adapt to meet the challenge. An understanding of the factors that make organizations effective, and a knowledge of how these factors interrelate, are the first steps towards developing the system for a firm’s customers. Logistics organizations must of necessity become more cost and service efficient. An understanding of the factors that affect a firm’s organizational effectiveness, along with strategies to reveal weaknesses or deficiencies, can help create more efficient logistics systems. Organizational changes form the basis for procedural modifications that can reduce costs or improve service. Many firms have shown significant improvements in their logistics cost-service mix as a result of organizational changes. Logistics organizations are generally structured along the following lines: strategic versus operational, centralized versus decentralized and line versus staff, in various combinations. There is no single ideal organizational structure, but there are important elements that comprise an effective organization. In general, the factors contributing to organizational effectiveness can be categorized as organizational characteristics, environmental characteristics, employee characteristics, and managerial policies and practices.

Full Text Available This article presents the results of a master thesis, which aimed at investigating the impact of strategic planning instruction on the speech performance of 6 L2 Brazilian learners. The participants, Letras-Inglês students, performed three now-and-there picture-cued narrative tasks under three different conditions: (1 no planning, (2 planning before instruction, and (3 planning after instruction. In addition, the participants filled in post-task questionnaires after the performance of each task, aiming at understanding their opinion on the conditions and tasks. Quantitative and qualitative analyses were conducted in order to examine participants’ oral production and perception, respectively. In general, there was no statistical evidence supporting the impact of instruction on participants’ oral planned performance; however, some statistical results approached significance, which may suggest some positive effects. Qualitative analyses provided positive evidence of the impact of strategic planning instruction on participant perception and their use of strategies during planning time. Moreover, the results of this study can contribute to the fields of Second Language Acquisition and Language Pegadogy.

This study examined the quality of the research base related to strategy instruction priming the underlying mathematical problem structure for students with learning disabilities and those at risk for mathematics difficulties. We evaluated the quality of methodological rigor of 18 group research studies using the criteria proposed by Gersten et al. and 10 single case design (SCD) research studies using criteria suggested by Horner et al. and the What Works Clearinghouse. Results indicated that 14 group design studies met the criteria for high-quality or acceptable research, whereas SCD studies did not meet the standards for an evidence-based practice. Based on these findings, strategy instruction priming the mathematics problem structure is considered an evidence-based practice using only group design methodological criteria. Implications for future research and for practice are discussed. © Hammill Institute on Disabilities 2013.

Educators can develop innovative instructional strategies to engage students within the philosophical framework of Constructivism. To that end, the authors used films--Hollywood movies--to enhance their curriculum on neurological and psychopathological illnesses. During the fourth quarter of a seven-quarter associate degree nursing program, students developed case studies of the disorders portrayed in selected films. The authors outline the methods used to implement this approach and discuss evaluations from student and faculty perspectives.

This study examined the resources and instructional strategies effective middle school science teachers use to improve content area reading skills. Reading instruction in the middle school years should follow the natural cognitive progression that occurs in the adolescent brain from learning to read to reading to learn. Scientific reading is a different type of reading than most middle school students are accustomed to. It is important to understand that students will continue to be expected to read non-fiction critically for success in the 21st century. Effective teachers know this, and they perceive themselves as teachers of reading regardless of the content area in which their expertise lies. This qualitative research study was conducted at a rural middle school with three science teachers who employ before, during, and after literacy strategies when reading the textbook content with their students. The methodologies used in this study were interviews, observations, and document collection. The results of this study revealed the students' reading difficulties perceived by the teacher participants, the literacy strategies used by the teacher participants, the instructional resources the teacher participants used to improve comprehension, and the need for professional development in content area literacy.

The practical nature of physics and its reliance on mathematical presentations and problem solving pose a challenge toward presentation of the course in an online environment for effective learning experience. Most first-time introductory college physics students fail to grasp the basic concepts of the course and the problem solving skills if the instructional strategy used to deliver the course is not compatible with the learners' preferred learning styles. This study investigates the effect of four instructional strategies based on four learning styles (listening, reading, iconic, and direct-experience) to improve learning for introductory college physics in an online environment. Learning styles of 146 participants were determined with Canfield Learning Style inventory. Of the 85 learners who completed the study, research results showed a statistically significant increase in learning performance following the online instruction in all four learning style groups. No statistically significant differences in learning were found among the four groups. However, greater significant academic improvement was found among learners with iconic and direct-experience modes of learning. Learners in all four groups expressed that the design of the unit presentation to match their individual learning styles contributed most to their learning experience. They were satisfied with learning a new physics concept online that, in their opinion, is either comparable or better than an instructor-led classroom experience. Findings from this study suggest that learners' performance and satisfaction in an online introductory physics course could be improved by using instructional designs that are tailored to learners' preferred ways of learning. It could contribute toward the challenge of providing viable online physics instruction in colleges and universities.

BACKGROUND/STUDY CONTEXT: This study investigates whether there is a need for age-specific computer-based instructional design. The authors examined the effect of two design principles, instructional coherence and advance organizers, on learning outcomes of older and younger adults. Instructional coherence refers to the idea that people learn more deeply when information not directly relevant to learning goals is removed from training. Advance organizers are organizing frameworks for intended training content. Participants consisted of younger and older adults (mean ages were 21.7 and 75.1, respectively). Younger adults were university students and older adults were recruited from various sources, including retirement homes, senior activity centers, and online communities. We used a 2 (young, old) × 2 (low coherence, high coherence) × 2 (no advance organizer, advance organizer) between-subjects design and analyzed data using a multivariate analysis of variance (MANOVA). Analyses revealed that (1) older adults performed worse on learning outcome measures compared with younger adults; (2) instructional coherence significantly improved the learning performance of both older and younger adults (Hypothesis 1 supported); and (3) advanced organizers improved the performance of older adults but did not affect the performance of younger adults in transfer tasks (Hypothesis 4 supported). The latter finding (that advance organizers had differential effects on older and younger adults) suggests that perhaps there is a need for age-specific instructional formats. Future researchers should further explore whether and how age affects the learning process by examining the effect of different design principles on learning outcomes of older and younger adults.

This dissertation reports findings from two studies that investigated the relationship between professional development and teachers' instructional practices in Science,Technology, Engineering, and Mathematics (STEM). The first program, the Indiana Science Initiative (ISI) focused on K-8 teachers and their use of inquiry-based science instruction in conjunction with curricular modules provided by the ISI program. The second program, Research Goes to School (RGS), focused on high school STEM teachers and their use of problem-based learning (PBL) as they implemented curricular units that they developed themselves at the RGS summer workshop. In-service teachers were recruited from both programs. They were observed teaching their respective curricular materials and interviewed about their experiences in order to investigate the following research questions: 1. How do teachers implement the reform-oriented instructional strategies promoted by their professional development experiences with the ISI or RGS? 2. What are the challenges and supports that influence teachers' use of the reform-oriented instructional strategies promoted by their professional development experiences with the ISI or RGS? To investigate these questions the fidelity of implementation was it was conceptualized by Century, Rudnick, and Freeman (2010) was used as a theoretical framework. The study of the ISI program was conducted during the program's pilot year (2010-11). Five teachers of grades 3 through 6 were recruited from three different schools. Participants were observed as they taught lessons related to the modules and they were interviewed about their experiences. Based on analysis of the data from the observations, using a modified version of the Science Teacher Inquiry Rubric (STIR) (Bodzin & Beerer, 2003), the participants were found to exhibit partial fidelity of implementation to the model of inquiry-based instruction promoted by the ISI. Based on data from the interviews, the

This study aims to develop instructional tools and implement it to see the effectiveness. The method used in this research referred to Designing Effective Instruction. Experimental research with two-group pretest-posttest design method was conducted. The instructional tools have been developed is cooperative learning model with predict-observe-explain strategy on the topic of cuboid and cube volume which consist of lesson plans, POE tasks, and Tests. Instructional tools were of good quality by criteria of validity, practicality, and effectiveness. These instructional tools was very effective for teaching the volume of cuboid and cube. Cooperative instructional tool with predict-observe-explain (POE) strategy was good of quality because the teacher was easy to implement the steps of learning, students easy to understand the material and students’ learning outcomes completed classically. Learning by using this instructional tool was effective because learning activities were appropriate and students were very active. Students’ learning outcomes were completed classically and better than conventional learning. This study produced a good instructional tool and effectively used in learning. Therefore, these instructional tools can be used as an alternative to teach volume of cuboid and cube topics.

Stringent admission criteria exist for nursing programs in the United States, but better predictors of success are needed to reduce student attrition. Research indicates that organized music experiences are associated with greater academic success. This exploratory study examined the association between early music experiences and undergraduate nursing student success. Findings suggest that students with a music background were more likely to graduate, have higher grade point averages, and pass the licensure examination. Previous music education might be considered as an additional predictor of nursing student success.

Full Text Available Many proven research-based instructional strategies have been developed for introductory college-level physics. Significant efforts to disseminate these strategies have focused on convincing individual instructors to give up their traditional practices in favor of particular research-based practices. Yet evidence suggests that the findings of educational research are, at best, only marginally incorporated into typical introductory physics courses. In this paper we present partial results of an interview study designed to generate new ideas about why proven strategies are slow to integrate in mainstream instruction. Specifically we describe the results of open-ended interviews with five physics instructors who represent likely users of educational research. We found that these instructors have conceptions about teaching and learning that are more compatible with educational research than with their self-described instructional practices. Instructors often blamed this discrepancy on situational factors that favor traditional instruction. A theoretical model is introduced to explain these findings.
This dissertation examines factors which may affect the educational effectiveness of science exhibits. Exhibit effectiveness is the result of a complex interaction among exhibit features, cognitive characteristics of the museum visitor, and educational outcomes. The purpose of this study was to determine the relative proportions of field-dependent and field-independent visitors in the museum audience, and to ascertain if the cognitive style of visitors interacted with instructional strategies to affect the educational outcomes for a computer-based science exhibit. Cognitive style refers to the self-consistent modes of selecting and processing information that an individual employs throughout his or her perceptual and intellectual activities. It has a broad influence on many aspects of personality and behavior, including perception, memory, problem solving, interest, and even social behaviors and self-concept. As such, it constitutes essential dimensions of individual differences among museum visitors and has important implications for instructional design in the museum. The study was conducted in the spring of 1998 at the Adler Planetarium and Astronomy Museum in Chicago. Two experimental treatments of a computer-based exhibit were tested in the study. The first experimental treatment utilized strategies designed for field-dependent visitors that limited the text and provided more structure and cueing than the baseline treatment of the computer program. The other experimental treatment utilized strategies designed for field-independent visitors that provided hypothesis-testing and more contextual information. Approximately two-thirds of the visitors were field-independent. The results of a multiple regression analysis indicated that there was a significant interaction between cognitive style and instructional strategy that affected visitors' posttest scores on a multiple-choice test of the content. Field-independent visitors out- performed the field

This study investigated the impact of different instructional strategies on students' understanding about the cell cycle in a general education biology course. Although several studies have documented gains in students' cell cycle understanding after instruction, these studies generally use only one instructional method, often without a comparison group. The goal of this study was to learn more about students' misconceptions about the cell cycle and how those ideas change after three different evidence-based learning experiences in undergraduate general education. Undergraduate students in six laboratory sections (n = 24; N = 144) in a large public institution in the western United States were surveyed pre- and post-instruction using a 14-item valid and reliable survey of cell cycle knowledge. Cronbach's alpha for the standard scoring convention was 0.264 and for the alternate scoring convention was 0.360, documenting serious problems with inconsistent validity and reliability of the survey. Operating as though the findings are at least a proxy for actual cell cycle knowledge, score comparisons by groups of interest were explored, including pre- and post-instruction differences among demographic groups of interest and three instructional settings: a bead modeling activity, a role-playing game, and 5E instructional strategy. No significant differences were found across groups of interest or by strategy, but some significant item-level differences were found. Implications and discussion of these shifts is noted in lieu of the literature.

Strategies of presenting instructional information affect the type of cognitive load imposed on the learner's working memory. Effective instruction reduces extraneous (ineffective) cognitive load and promotes germane (effective) cognitive load. Eighty first-year students from two veterinary schools completed a two-section questionnaire that evaluated their perspectives on the educational value of a computer-based instructional program. They compared the difference between cognitive loads imposed by paper-based and computer-based instructional strategies used to teach the anatomy of the canine skeleton. Section I included 17 closed-ended items, rated on a five-point Likert scale, that assessed the use of graphics, content, and the learning process. Section II included a nine-point mental effort rating scale to measure the level of difficulty of instruction; students were asked to indicate the amount of mental effort invested in the learning task using both paper-based and computer-based presentation formats. The closed-ended data were expressed as means and standard deviations. A paired t test with an alpha level of 0.05 was used to determine the overall mean difference between the two presentation formats. Students positively evaluated their experience with the computer-based instructional program with a mean score of 4.69 (SD=0.53) for use of graphics, 4.70 (SD=0.56) for instructional content, and 4.45 (SD=0.67) for the learning process. The mean difference of mental effort (1.50) between the two presentation formats was significant, t=8.26, p≤.0001, df=76, for two-tailed distribution. Consistent with cognitive load theory, innovative computer-based instructional strategies decrease extraneous cognitive load compared with traditional paper-based instructional strategies.
Full Text Available The paper primarily stresses on exploring the teacher’s voice toward the application of metacognitive strategy with audio-visual aid in improving listening comprehension. The metacognitive strategy model applied in the study was inspired from Vandergrift and Tafaghodtari (2010 instructional model. Thus it is modified in the procedure and applied with audio-visual aids for improving listening comprehension. The study’s setting was at SMA Negeri 2 Parepare, South Sulawesi Province, Indonesia. The population of the research was the teacher of English at tenth grade at SMAN 2. The sample was taken by using random sampling technique. The data was collected by using in depth interview during the research, recorded, and analyzed using qualitative analysis. This study explored the teacher’s response toward the modified model of metacognitive strategy with audio visual aids in class of listening which covers positive and negative response toward the strategy applied during the teaching of listening. The result of data showed that this strategy helped the teacher a lot in teaching listening comprehension as the procedure has systematic steps toward students’ listening comprehension. Also, it eases the teacher to teach listening by empowering audio visual aids such as video taken from youtube.

Training dentists today is challenging as they are expected to provide a wide range of dental care. In the provision of good dental care, soft skills are equally important as clinical skills. Therefore in dental education the development of soft skills are of prime concern. This study sought to identify the development of soft skills when dental students are paired in their clinical training. In this perception study, four open-ended items were used to elicit students' feedback on the appropriateness of using clinical pairing as an instructional strategy to promote soft skills. The most frequently cited soft skills were teamwork (70%) and communication (25%) skills. However, both negative and positive behaviours were reported. As for critical thinking and problem solving skills, more positive behaviours were reported for abilities such as to explain, analyze, find ideas and alternative solutions, and make decisions. Leadership among peers was not evident as leading without legitimate authority could be a hindrance to its development. If clinical pairing is to be used as an effective instructional strategy to promote soft skills amongst students, clear guidelines need to be developed to prepare students to work in a dental team and the use of appropriate assessment tools can facilitate the development of these soft skills. © 2013 John Wiley & Sons A/S.

Recent findings concerning mathematics assessment indicate that students in Japan consistently score above international averages. Researchers have examined specific mathematics beliefs and instructional strategies associated with mathematics achievement for students in Japan. This study examined relationships among self-beliefs, classroom instructional strategies, and mathematics achievement for a large national sample of students (N=4,207) from the TIMSS 2003 international sample of fourth graders in Japan. Several significant relationships between mathematics beliefs and test scores were found; a number of classroom teaching strategies were also significantly associated with test scores. However, multiple regression using the complete set of five mathematics beliefs and five instructional strategies explained only 25.1% of the variance in mathematics achievement test scores.

Interventions and media campaigns promoting household disaster preparedness have produced mixed results in affecting behaviors. In large part, this is due to the limited application of instructional design strategies and behavior theory, such as the Transtheoretical Model (TTM). This study describes the development and evaluation of Ready CDC, an intervention designed to increase household disaster preparedness among the Centers for Disease Control and Prevention (CDC) workforce. (1) Describe the instructional design strategies employed in the development of Ready CDC and (2) evaluate the intervention's impact on behavior change and factors influencing stage progression for household disaster preparedness behavior. Ready CDC was adapted from the Federal Emergency Management Agency's (FEMA's) Ready campaign. Offered to CDC staff September 2013-November 2015, it consisted of a preassessment of preparedness attitudes and behaviors, an in-person training, behavioral reinforcement communications, and a 3-month follow-up postassessment. Ready CDC employed well-accepted design strategies, including presenting stimulus material and enhancing transfer of desired behavior. Excluding those in the TTM "maintenance" stage at baseline, this study determined 44% of 208 participants progressed at least 1 stage for developing a written disaster plan. Moreover, assessment of progression by stage found among participants in the "precontemplation" (n = 16), "contemplation" (n = 15), and "preparation" (n = 125) stages at baseline for assembling an emergency kit, 25%, 27%, and 43% moved beyond the "preparation" stage, respectively. Factors influencing stage movement included knowledge, attitudes, and community resiliency but varied depending on baseline stage of change. Employing instructional strategies and behavioral theories in preparedness interventions optimizes the potential for individuals to adopt preparedness behaviors. Study findings suggest that stage movement toward

Full Text Available This small-scale quasi-experimental study compared the effects of metacognitive strategy instruction using two pedagogical approaches on the metacognitive awareness of Malaysian ESL listeners. Embedded and direct strategy instruction was delivered using the Metacognitive Pedagogical Sequence and Cognitive Academic Language Learning Approach instructional models respectively. 45 tertiary level students were randomly selected and assigned to two treatment groups to receive metacognitive instruction over a training period of five weeks. Paired-samples t-test results on participants‟ metacognitive awareness, as measured using the Metacognitive Awareness Listening Questionnaire (MALQ were inclusive despite significant improvements in their IELTS listening scores. No significant development was recorded in the overall MALQ scores but there were significant changes in three out of the five metacognitive awareness factors. Results further layered according to participants‟ listening proficiency levels (low, intermediate and high to examine if differences existed among the listening levels similarly showed no significant difference. These results suggest that ESL listeners‟ metacognitive awareness may not be easily developed with strategy instruction, regardless of the instructional approaches.

It has been argued that an analytic approach, using a step-by-step analysis of the radiographic features of an abnormality, is ideal. Alternative research suggests that novices can successfully employ non-analytic reasoning. Many of these studies do not take instructional methodology into account. This study evaluated the effectiveness of non-analytic and analytic strategies in radiographic interpretation and explored the relationship between instructional methodology and diagnostic strategy. Second-year dental and dental hygiene students were taught four radiographic abnormalities using basic science instructions or a step-by-step algorithm. The students were tested on diagnostic accuracy and memory immediately after learning and one week later. A total of seventy-three students completed both immediate and delayed sessions and were included in the analysis. Students were randomly divided into two instructional conditions: one group provided a diagnostic hypothesis for the image and then identified specific features to support it, while the other group first identified features and then provided a diagnosis. Participants in the diagnosis-first condition (non-analytic reasoning) had higher diagnostic accuracy then those in the features-first condition (analytic reasoning), regardless of their learning condition. No main effect of learning condition or interaction with diagnostic strategy was observed. Educators should be mindful of the potential influence of analytic and non-analytic approaches on the effectiveness of the instructional method.

Full Text Available This paper addresses the question of how virtual organizations that yield strategic advantage are formed. The study uses grounded theory to investigate the organizational processes and structure that facilitate the formation of a successful virtual organization. We present a case study of one virtual organization, a university in Australia, which has gained strategic advantage from alliances supported by information and communication technologies (ICT. The university is now the fastest growing university in Australia in terms of international student enrolments. The case study suggests that this commercial success is based on responsiveness to environmental conditions and organizational factors that include a long history as a distance education provider (an early form of virtualization, sophisticated information communication technologies, and a culture of innovation and risk-taking. The development processes observed included evolutionary growth, decisive actions and management leadership at opportune moments, and examples of technological and entrepreneurial innovations led by individuals. Significant decision making occurred outside formal strategic planning processes.
Full Text Available The Global era has had a great impact on the existence of English as a global language which requires students to be good at its every skill. It is believed that students’ English could be enhanced well with the use of certain strategies, one of which is Interactive Read Aloud Instructional Strategy (IRAIS. This study was aimed at examining the efﬁcacy of IRAIS to help students to improve their English literacy achievements. Forty five out of 746 students were selected randomly as sample based on their grade levels (7th, 8th, 9th and their levels of comprehension. By using time series design, these students were given interventions for three months using IRAIS and their English achievements were obtained from pre- and post-tests of four English literacy skills. During the interventions, the progress of the students was also monitored regularly by using three formative tests.The results showed consistent progress on the students’ achievement during the interventions and upon their total English literacy achievement after the interventions. Among the four English literacy skills, the most significant improvement was in listening followed by writing, reading, and speaking. In terms of aspects of each literacy skill, the highest achievement scores were in inference of listening, narrative techniques of writing, vocabulary of reading, and vocal expression of speaking. These findings lead to the conclusion that IRAIS is an effective strategy in helping students to improve their level of English proficiency.

In order to develop an expert-like mental model of complex systems, causal reasoning is essential. This study examines the differences between forward and backward instructional strategies' in terms of efficiency, students' learning and progression of their mental models of the electronic transport chain in an undergraduate metabolism course (n = 151). Additionally, the participants' cognitive flexibility, prior knowledge, and mental effort in the learning process are also investigated. The data were analyzed using a series of general linear models to compare the strategies. Although the two strategies did not differ significantly in terms of mental model progression and learning outcomes, both groups' mental models progressed significantly. Mental effort and prior knowledge were identified as significant predictors of mental model progression. An interaction between instructional strategy and cognitive flexibility revealed that the backward instruction was more efficient than the conventional (forward) strategy for students with lower cognitive flexibility, whereas the conventional instruction was more efficient for students with higher cognitive flexibility. The results are discussed and suggestions for future research on the possible moderating role of cognitive flexibility in the area of health education are presented.

Increasingly, English Language Learners (ELLs) are mainstreamed in science classes. As a result, science teachers must assume responsibility for these students' education. Currently, state tests show a wide performance gap between ELLs and non-ELLs in science and other content area courses. For instance, the Massachusetts Comprehensive Assessment System (MCAS) shows a two years average performance of 6% for ELLs and 33% for non-ELLs in English Language Arts (ELA), Mathematics, and Science and Technology, a 27% performance gap (Lachat, 2000). The use of research based effective teaching strategies for ELLs is indispensable in order to meet ELLs' learning needs (Jarret, 1999). The purpose of this study was to determine if differences exist between ELLs and non-ELLs regarding instructional strategies that secondary science teachers employ. Four areas were examined: instructional strategies mainstreamed ELLs and non-ELLs report as being most frequently employed by their science teachers, instructional strategies ELLs and non-ELLs consider most effective in their learning, the existing differences between ELLs and non-ELLs in the rating of effectiveness of instructional strategies their teachers currently practice, and factors impacting ELLs and non-ELLs' performance on high-stakes tests. This study was conducted in two urban high schools in Southern New England. The sample (N = 71) was based on the non-probability sampling technique known as convenience sampling from students registered in science classes. The questionnaire was designed based on research-based effective teaching strategies (Burnette, 1999; Ortiz, 1997), using a Likert-type scale. Several findings were of importance. First, ELLs and non-ELLs reported similar frequency of use of effective instructional strategies by teachers. However, ELLs and non-ELLs identified different preferences for strategies. Whereas non-ELLs preferred connecting learning to real life situations, ELLs rated that strategy as least

Full Text Available Clinical reasoning is a critical and complex skill that medical students have to develop in the course of their training. Although research on medical expertise has successfully examined the different components of that skill, designing educational interventions that support the development of clinical reasoning in students remains a challenge for medical educators. The theory of medical expertise describes how students׳ medical knowledge develops and is progressively restructured during their training and in particular through clinical exposure to patient problems. Instructional strategies to foster students’ learning from practice with clinical cases are scarce. This article describes the use of self-explanation as such a strategy. Self-explanation is an active learning technique of proven effectiveness in other domains which consists of having students explaining to themselves information on to-be-learned materials. The mechanisms through which self-explanation fosters learning are described. Self-explanation promotes knowledge development and revision of mental representations through elaboration on new information, organisation and integration of new knowledge into existing cognitive structures and monitoring of the learning process. Subsequently, the article shows how self-explanation has recently been investigated in medicine as an instructional strategy to support students׳ clinical reasoning. Available studies have demonstrated that students׳ diagnostic performance improves when they use self-explanation while solving clinical problems of a less familiar clinical topic. Unfamiliarity seems to trigger more self-explanations and to stimulate students to reactivate relevant biomedical knowledge, which could lead to the development of more coherent representations of diseases. The benefit of students׳ self-explanation is increased when it is combined with listening to residents׳ self-explanation examples and with prompts. The

Family involvement is an essential element of language intervention with severely handicapped children for several reasons. First, the parent-child interaction is the focus of normal language development, and can be a powerful impetus in language learning for handicapped children. Second, limited generalization and maintenance of skills often occur when they are acquired in environments that do not also teach the appropriate use of skills. Third, parents can be successful intervention agents and may generalize their skills to other interactions with their child. Training conducted in the home must be compatible with that environment: it should involve only those skills that are of immediate use in the home. The Instructional Communication Strategy described herein represents such a program. It is a synthesis of training strategies used with normal and handicapped children, and is applicable regardless of child's level of functioning, age, or handicapping condition. This training model involves considerable modification in the role of speech-language pathologists dealing with the severely handicapped. The professional's skills are best utilized for assessment, program development, monitoring progress, and training specialized skills. The parents provide most of the direct training; however, professionals are also utilized for the child's maximum benefit.

Literature reviews on hypermedia learning have yet failed to show consistent positive effects of learner-controlled nonlinear information access. We argue that a possible reason for this lack of evidence in favor of hypermedia learning results from the fact that not sufficient attention is paid to the strategies of information utilization learners deploy. The few studies that do analyze these strategies fail to link them to an instructional approach, which hampers a deeper interpretation of s...
Does strategy instruction on the Rey-Osterrieth Complex Figure task lead to transferred performance improvement on the Modified Taylor Complex Figure task? A randomized controlled trial in school-aged children.
Resch, Christine; Keulers, Esther; Martens, Rosa; van Heugten, Caroline; Hurks, Petra
Providing children with organizational strategy instruction on the Rey Osterrieth Complex Figure (ROCF) has previously been found to improve organizational and accuracy performance on this task. It is unknown whether strategy instruction on the ROCF would also transfer to performance improvement on copying and the recall of another complex figure. Participants were 98 typically developing children (aged 9.5-12.6 years, M = 10.6). Children completed the ROCF (copy and recall) as a pretest. Approximately a month later, they were randomized to complete the ROCF with strategy instruction in the form of a stepwise administration of the ROCF or again in the standard format. All children then copied and recalled the Modified Taylor Complex Figure (MTCF). All productions were assessed in terms of organization, accuracy and completion time. Organization scores for the MTCF did not differ for the two groups for the copy production, but did differ for the recall production, indicating transfer. Accuracy and completion times did not differ between groups. Performance on all measures, except copy accuracy, improved between pretest ROCF and posttest MTCF production for both groups, suggesting practice effects. Findings indicate that transfer of strategy instruction from one complex figure to another is only present for organization of recalled information. The increase in RCF-OSS scores did not lead to a higher accuracy or a faster copy or recall.

This qualitative study aimed at exploring how health professionals use theories and models from the field of education to create ehealth and mhealth education interventions in an effort to provide insights for future research and practice on the development and implementation of health promotion initiatives. A purposeful sample of 12 participants was selected, using criterion and snowballing sampling strategies. Data were collected and analyzed from semistructured interviews, planning materials, and artifacts. The findings revealed that none of the participants used a specific learning theory or an instructional model in their interventions. However, based on participants' description, three themes emerged: (1) connections to behaviorist approaches to learning, (2) connections to cognitivist approaches to learning, and (3) connections to constructivist approaches to learning. Suggested implications for practice are (1) the design of a guidebook on the interplay of learning theories, instructional models, and health education and (2) the establishment of communities of practice. Further research can (1) investigate how learning theories and models intertwine with health behavior theories and models, (2) evaluate how the different instructional strategies presented in this study affect learning outcomes and health behavior change processes, and (3) investigate factors behind the instructional strategies choices made by health professionals. © 2016 Society for Public Health Education.
Full Text Available Nowadays, striving to find an efficient way for developing or identifying appropriate knowledge management strategies in organizations has become so critical. Researchers and practitioners have attached great importance to information pyramids in organizations and have highlighted the lack of trained and skilled staff as a serious problem. On the other hand, having more flexibility at workplace, offering better service, and fulfilling customers' demands require a strategy for managing knowledge and its consequence. Knowledge management provides a wide range of different strategies and methods for identifying, creating, and sharing knowledge in organizations. This deep insight which consists of individual, organization’s experience, knowledge, and understanding helps organization respond to both internal and external stimuli and act in harmony. One fact which has seemingly achieved a consensus is the need for different strategies of knowledge management. Among the wide range of various and often unclear knowledge management strategies one can choose a strategy in a specific situation. The aim of this paper is to respond to strategic questions which emphasize competitive intelligence and internal knowledge retrieval system. The implications are discussed in detail.
Full Text Available One of important aspects of strategic management is the instrumental aspect included in a rich set of methods and techniques used at particular stages of strategic management process. The object of interest in this study is the development of views and the implementation of strategy as an element of strategic management and instruments in the form of methods and techniques. The commonly used method in strategy implementation and measuring progress is Balanced Scorecard (BSC. The method was created as a result of implementing the project “Measuring performance in the Organization of the future” of 1990, completed by a team under the supervision of David Norton (Kaplan, Norton 2002. The developed method was used first of all to evaluate performance by decomposition of a strategy into four perspectives and identification of measures of achievement. In the middle of 1990s the method was improved by enriching it, first of all, with a strategy map, in which the process of transition of intangible assets into tangible financial effects is reflected (Kaplan, Norton 2001. Strategy map enables illustration of cause and effect relationship between processes in all four perspectives and performance indicators at the level of organization. The purpose of the study being prepared is to present methodical conditions of using strategy maps in the strategy implementation process in organizations of different nature.
Full Text Available The present paper aims at investigating the application of an instructional method specifically focused on the expansion of metacognitive awareness and its effect on Serbian EFL students’ listening comprehension. The current study is a follow-up research of a similar study by Vandergrift and Tafaghodtari (2010. However, we sought to expand the previous research by investigating the relationship between the students’ current level of L2 (target language vocabulary and listening test scores. Our study likewise differed in the sample of participants, the target language, teaching and testing material used, and the duration of the very experiment. To answer the proposed research questions we conducted an experiment with 57 Serbian secondary school EFL (English as a Foreign Language learners divided into experimental (n=27 and control group (n=30. The results of the pre- and post-tests of the two groups showed the beneficial effects of developing metacognitive strategies and the strong positive correlation between the level of vocabulary and listening comprehension. The paper underlines important pedagogical implications especially regarding the enhancement of metacognitive awareness and vocabulary proficiency of students in order to improve performance on listening comprehension tasks.

In this paper the authors discuss how the concept of dynamic (cognitive) assessment and instruction might relate to the assessment and instruction of at-risk foreign/second language learners. They describe its relevance to a diagnostic/prescriptive approach to instruction for teaching a foreign language to students with identified dyslexia and other at-risk students. They explain how to assess learners' knowledge of the native/foreign/second language through questions and guided discovery. Examples in German and English illustrate its application to foreign/second language instruction.

Throughout most of modern busi ness history, corporations have attempted to unlock value by matching their structures to their strategies: Centralization by function. Decentralization by product category or geographic region. Matrix organizations that attempt both at once. Virtual organizations. Networked organizations. Velcro organizations. But none of these approaches has worked very well. Restructuring churn is expensive, and new structures often create new organizational problems that are as troublesome as the ones they try to solve. It takes time for employees to adapt to them, they create legacy systems that refuse to die, and a great deal of tacit knowledge gets lost in the process. Given the costs and difficulties involved in finding structural ways to unlock value, it's fair to raise the question: Is structural change the right tool for the job? The answer is usually no, Kaplan and Norton contend. It's far less disruptive to choose an organizational design that works without major conflicts and then design a customized strategic system to align that structure to the strategy. A management system based on the balanced scorecard framework is the best way to align strategy and structure, the authors suggest. Managers can use the tools of the framework to drive their unit's performance: strategy maps to define and communicate the company's value proposition and the scorecard to implement and monitor the strategy. In this article, the originators of the balanced scorecard describe how two hugely different organizations--DuPont and the Royal Canadian Mounted Police-used corporate scorecards and strategy maps organized around strategic themes to realize the enormous value that their portfolios of assets, people, and skills represented. As a result, they did not have to endure a painful series of changes that simply replaced one rigid structure with another.

Full Text Available Creative Arts is a core and compulsory subject in Nigerian upper basic classes, but the students’ performance over the years indicated high failure. Instructional strategies play a pivotal role in improving students’ performance. Computer-based instructions such as animated drawings could be a possible solution. This research adopted the design and development type. The between groups repeated measure design compared pretest and post-test scores of participants to identify differences after treatment. To validate the instruments, test re-test method was used; Pearson product moment correlation co-efficient yielded a reliability value of .94. Also, 674 upper basic school students consisting of 387 public and 287 private schools students, 338 males, and 336 females were involved in the study. Seven research questions and seven corresponding hypotheses were raised and tested respectively. ANOVA and t-test were used for hypotheses testing. Findings of the study showed that computer-based animated drawings instruction enhanced performance. It was recommended among others that the classroom teacher should embrace the strategy for Creative Arts classes; authors and curriculum planners should create more opportunities for computer-based animated drawing in explaining procedures for instruction to enhance learning and improve performance.
Full Text Available The kind of realized mission inflows the sensitivity to risk. Among other factors, the risk results from decision about liquid assets investment level and liquid assets financing. The higher the risk exposure, the higher the level of liquid assets. If the specific risk exposure is smaller, the more aggressive could be the net liquid assets strategy. The organization choosing between various solutions in liquid assets needs to decide what level of risk is acceptable for her owners (or donors and / or capital suppliers. The paper shows how, in authors opinion, decisions, about liquid assets management strategy inflow the risk of the organizations and its economicalresults during realization of main mission. Comparison of theoretical model with empirical data for over 450 Silesian nonprofit organization results suggests that nonprofit organization managing teams choose more risky aggressive liquid assets solutions than for-profit firms.
Full Text Available The need for effective human resources strategies, which have a strong role in achieving goals has been a subject extensively treated in the literature. Thus, those interested in this field could learn about the stages of development of human resources strategy, the criteria necessary to be considered, features that should have a human resource strategy properly adopted and the modalities for its implementation. However, it has neglected an important aspect essential, namely, who should formulate strategy and human resources of an organization who is responsible for its implementation. In this paper we focused attention on identifying new aspects of the human resources strategy: people involved in adopting and implementing human resources strategy. The present study is one of the fundamental theoretical literature. The facts are not merely generalizing, but is analysis, opinion and personal conclusions. However, they can represent a focal point for business, prompting an awareness among the lead actors in a company, the need straightening attention to the foregoing. The overall conclusion is that it is not enough for an organization to have a human resources strategy. To be fair one, to adopt and implement them have involved those individuals who have the necessary capacity and not the responsibility of everyone. Pawns should be the main human resources manager and senior manager, followed by operational.

Unlike consumer goods industries, healthcare has been slow to implement technolo gies that support exchange of data in patients' health records. This results in avoid able medication errors, avoidable hospital readmissions, unnecessary duplicate testing, and other inefficient or wasteful practices. Community-based regional health information exchange (HIE) organizations have evolved in response to federal aims to encourage interoperability, yet little is known about their strategic approach. We use the lens of institutional and strategic management theories to empirically explore the differences in business strategies deployed in HIEs that are, to date, financially sustainable versus those that are not. We developed a 20-question survey targeted to CEOs to assess HIE business strategies. Our sample consisted of 60 community-based exchanges distributed throughout the United States, and we achieved a 58% response rate. Questions centered on competitive strategy and financial sustainability. We relied on logistic regression methods to explore relationships between variables. Our regression identified characteristics common to sustainable organizations. We defined sustainability as revenues exceeding operational costs. Seventeen of the 35 organizations (49%) defined themselves as currently sustainable. Focus and cost leadership strategies were significantly associated with sustainability. Growth strate gies, which were much more common than other strategies, were not associated with sustainability. We saw little evidence of a differentiation strategy (i.e., the basis of competition whereby the attributes of a product or service are unmatched by rivals). Most CEOs had a relatively optimistic outlook, with 60% stating they were confident of surviving over the next 5 years; however, nearly 9% of the organizations were in some phase of divestiture or exit from the market. HIEs are evolving differently based on local leadership decisions, yet their strategic approach is
The Site-Specific Waste Management Instruction (SSWMI) provides guidance for the management of waste generated from field-sampling activities performed by the Environment Restoration Contractor (ERC) Sampling Organization that are not managed as part of a project SSWMI. Generally, the waste is unused preserved groundwater trip blanks, used and expired calibration solutions, and other similar waste that cannot be returned to an ERC project for disposal. The specific waste streams addressed by this SSWMI are identified in Section 2.0. This SSWMI was prepared in accordance with BHI-EE-02, Environmental Requirements. Waste generated from field sample collection activities should be returned to the project and managed in accordance with the applicable project-specific SSWMI whenever possible. However, returning all field sample collection and associated waste to a project for disposal may not always be practical or cost effective. Therefore, the ERC field sampling organization must manage and arrange to dispose of the waste using the (Bechtel Hanford, Inc. [BHI]) Field Support Waste Management (FSWM) services. This SSWMI addresses those waste streams that are the responsibility of the field sampling organization to manage and make arrangements for disposal

Studies have shown that there is a need for pedagogical content knowledge among science teachers. This study investigates two primary teachers and their objectives in choosing inquiry- and context-based instructional strategies as well as the relation between the choice of instructional strategies and the teachers' knowledge about of students' understanding and intended learning outcomes. Content representations created by the teachers and students' experiences of the enacted teaching served as foundations for the teachers' reflections during interviews. Data from the interviews were analyzed in terms of the intended, enacted, and experienced purposes of the teaching and, finally, as the relation between intended, enacted, and experienced purposes. Students' experiences of the teaching were captured through a questionnaire, which was analyzed inductively, using content analysis. The results show that the teachers' intended teaching objectives were that students would learn about water. During the enacted teaching, it seemed as if the inquiry process was in focus and this was also how many of the students experienced the objectives of the activities. There was a gap between the intended and experienced objectives. Hardly any relation was found between the teachers' choice of instructional strategies and their knowledge about students' understanding, with the exception that the teacher who also added drama wanted to support her students' understanding of the states of water.

Full Text Available Any increase in the level of sustainable food consumption in Bangkok requires both providers and consumers to change their behavior and strategies in a more sustainable direction. This paper focuses on provider’s side and examines the strategies that food providers in Bangkok use to reach the Thai consumers with their sustainable food offers. This paper looks at the “niche” specialized shops which are the first group of organic food provider and currently provide organic food to consumers in Bangkok. A focus group discussion was organized with representatives of the specialized shops in order to discuss and to assess a number of different strategies that could be applied when trying to sell organic food to consumers in Bangkok. The study found that the specialized shops in Bangkok are “small, specialized and beautiful”. The specialized shops in Bangkok form the “Green Market Network” to work together and empower individual shop owners. The major tasks of the network are to procure sufficient sustainable food from reliable sources for the individual shops, to improve their businesses by learning from each other’s experiences and to expand the market for their products. The specialized shops are not so much focused on certification but, instead rely on trust. The specialized shops communicate with consumers in an informal and friendly way, talking directly to them in the shop and organizing activities with them.
Although innovations in space education were introduced in many developing countries with good intentions, too many changes and challenges in the existing system have often penalized those who needed them the most. Consequently, the students and teachers in the underprivileged schools face isolation, neglect and coupled with inadequate pedagogic attention, poor infrastructure and insufficient resources, inadvertently suffer. Surprisingly, these deprived school students possess cognitive capabilities of comprehending nature. One of the most compelling situations in Indian school education is that the syllabus is often modified haphazardly without the necessary groundwork and infrastructure to implement it. Apparently, there has neither been teaching nor learning on applied knowledge. Despite the growth in communication and technology applications in space education, inequalities continue to exist in developing countries. In our present society many crucial services are provided by space and it becomes imperative that students have a comprehensive knowledge of space and space based technologies. To realize these objectives, we have adopted a comprehensive and holistic capacity building mechanism which incorporates differentiated instructional strategy on teaching space education in underprivileged schools. Because differentiation and scaffolding techniques yield similar instructional goals, we have blended together both the approaches to the point of being indistinguishable and this proved successful. Initiation was done through the setting up of an Astronomy Club in a backward area in Hyderabad and necessary infrastructure was provided by one of the authors. A state of the art audio-visual room with LCD Projector for ICT mode of presentations of various astronomy and space topics, having a seating capacity of 50 students is in place. A laptop, printer and Wi-Fi connection exists. In addition, visual charts on various celestial phenomena and objects, inspirational

Full Text Available While asset markets are traditionally left to economic inquiry, the paper shows that there is both a legal possibility and an incentive for organizing within such markets and for exercising market share-based strategic maneuvering. It proposes, based on sensemaking theory, Implicit Organizations in asset markets to exploit equivocality for momentum trading strategies. An Implicit Organization fulfills the criteria of an organization, while maintaining the image of a perfect market. Its members coordinate via market signals and fixed investment time windows to ensure positive returns to strategic maneuvering in asset markets. In support of hypotheses derived from sensemaking theory, results of empirical studies from two different investment contexts (Xetra and NYSE provide evidence that equivocal analysts’ recommendations predict investment returns after a fixed time period.

The focused factory is one of the concepts that decision-makers have adopted for improving health care delivery. However, disorganized definitions of focus have led to findings that cannot be utilized systematically. The purpose of this paper is to discuss strategic options to focus health care operations. First the literature on focus in health care is reviewed revealing conceptual challenges. Second, a definition of focus in terms of demand and requisite variety is defined, and the mechanisms of focus are explicated. A classification of five focus strategies that follow the original idea to reduce variety in products and markets is presented. Finally, the paper examines managerial possibilities linked to the focus strategies. The paper proposes a framework of five customer-oriented focus strategies which aim at reducing variety in different characteristics of care pathways: population; urgency and severity; illnesses and symptoms; care practices and processes; and care outcomes. Empirical research is needed to evaluate the costs and benefits of the five strategies and about system-level effects of focused units on competition and coordination. Focus is an enabling condition that needs to be exploited using specific demand and supply management practices. It is essential to understand how focus mechanisms differ between strategies, and to select focus that fits with organization's strategy and key performance indicators. Compared to previous more resource-oriented approaches, this study provides theoretically solid and practically relevant customer-oriented framework for focusing in health care.

Debate continues over the benefits, or otherwise, of single-sex classes in science and mathematics, particularly for the performance of girls. Previous research and analyses of the circumstances surrounding the implementation of single-sex classes warn that the success of the strategy requires due consideration of the nature of the instructional environment for both boys and girls, together with appropriate support for the teachers involved. This article reports the circumstances under which teachers were able to implement gender-inclusive strategies in single-sex science classes in coeducational high schools and documents some of the difficulties faced. The study was part of the Single-Sex Education Pilot Project (SSEPP) in ten high schools in rural and urban Western Australia. Qualitative and quantitative data were gathered during the project from teachers, students and classroom observations. Overall, it was apparent that single-sex grouping created environments in which teachers could implement gender-inclusive science instructional strategies more readily and effectively than in mixed-sex settings. Teachers were able to address some of the apparent shortcomings of the students' previous education (specifically, the poor written and oral communication of boys and the limited experience of girls with 'hands-on' activities and open-ended problem solving). Further, in same-sex classrooms, sexual harassment which inhibited girls' learning was eliminated. The extent to which teachers were successful in implementing gender-inclusive instructional strategies, however, depended upon their prior commitment to the SSEPP as a whole, and upon the support or obstacles encountered from a variety of sources, including parents, the community, students, and non-SSEPP teachers.

The current study focuses on communication strategies employed by rare disease patient organizations. The aims of these organizations are: educate and inform the public about rare diseases, raise awareness of the problems related to rare diseases, and achieve social legitimacy in order give visibility to their demands. We analyzed the portrayal of rare disease and patient organizations by Spain's major media organizations in terms of circulation and viewership - the press (El País, El Mundo, La Vanguardia,ABC and El Periódico), radio (CadenaSer, Onda Cero, Cope and RNE), and television (Telecinco, Antena 3, La 1, La Sexta, Cuatro) -between 2012 and 2014.We then carried out a descriptive analysis of communication activities performed via the World Wide Web and social networks by 143 national organizations. Finally, we conducted a telephone questionnaire of a representative sample of 90 organizations in order to explore the association between media presence and funding and public image. The triangulation of quantitative and qualitative methods allowed us to meet the study's objectives. Increased visibility of the organizations afforded by an increase in the coverage of the topic by the medialed to an increase in membership - but not in donations - and increased awareness of these diseases.

Full Text Available This article reports how Hmong parents were involved in an educational research study to examine their views on a structured reading instruction protocol developed in English and then translated into Hmong for Hmong children identified with disabilities. Six Hmong female parents were interviewed using a semi-structured interview. The responses from the interviews revealed that Hmong parents of disabled children are not only very concerned about seeking education equity, but that they need more communication and knowledge about their children’s education. The research methodology revealed a process to engage Hmong parents in discussing their perceptions about schools and their relationships with schools as well as classroom instruction.
In this paper we look respectively at three specific examples showing program strategies for maintenance management, organization and planning. Starting with preventive maintenance optimization, we will look at one Bruce B Predefined task on the Reactor Regulating System to illustrate reduced maintenance requirement, a maintenance management strategy. Next discussed is the organizational strategy at Darlington to have an engineering program meet the jurisdictional requirements for maintaining certification for TSSA registered pressure vessels. The last look-see will show the earned value of the planning for the first Pickering A unit to be returned to service. Finally all the above is tied together in a compare and contrast of what works and what could be improved upon. (author)

In recent years, environmental nongovernment organizations (NGOs) have been active in alerting the public and governments to tropical forest issues. Many feel that these efforts have begun to affect the trade in tropical timber and influence the perceptions of logging in the tropics. However, the influence of environmental organizations is not restricted to tropical timber trade but has the potential to impact the global wood products industry. The wood products industry has an opportunity to address these pressures by understanding the strategies and perceptions of the environmental community on this issue and developing proactive strategies to deal with the situation. This study included a phase 1 prestudy, which reported the results of interview with over 39 environmental NGOs in both the US and Europe to develop an overview of this complex industry. A phase 2 followup fax questionnaire was administered to the most relevant US environmental NGOs in order to classify them on two important criteria: (1) their level of specialization; and (2) their organizational strategy. This paper provides an overview of the complex issues in the environmental debate regarding tropical deforestation and how environmental organizations are attempting to address these issues

CONTEXT-Most reports on organ donation have been related to the importance of support for families, explanations of brain death, and the appeal for organ donation. In contrast, no reports have addressed organ donation from the perspective of intervention in cases of "sudden mourning" and the practical aspects of how to facilitate donation in such cases. OBJECTIVE-To develop a specific strategy for professional intervention in cases of imminent death to bring the family to a state of cognitive and emotional preparedness that will enable them to accept the tragic news, donate organs, and then take leave of the deceased. METHOD-The strategy presented here was developed on the basis of the records of donor coordinators who documented their interaction with families; consultations with professionals in the fields of marketing, persuasion, and negotiating; research conducted on families who did or did not donate organs; and statements made by family members of donors in focus and support groups in more than 10 years. RESULTS-The strategic approach includes early-stage rules such as staff self-awareness, and then later, critical stages of the process that take place before and at the time of determination of brain death: preparation for and the notification of death itself and the request for organ donation, including persuasion skills, coping with resistance and expressions of anger, and physical leave-taking from the deceased. CONCLUSIONS-The flexible, strategic approach set out here is designed to maximize the chances of procuring organ donation while protecting the family's rights and welfare.

Organic cocrystals that are composed of two or more components usually exhibit novel, unpredictable, and even unique properties rather than a simple combination of the properties of their components, such as white-light emission, ambipolar charge transport, nonlinear optics, and ferroelectricity. Since cocrystal engineering represents a novel strategy for synthesizing multifunctional materials, which opens the door for molecular collaborative innovation, it has aroused much attention in recent years. However, as it is also a relatively new research field, it is only in its early stages of development. In order to provide readers with an understanding of the future design of cocrystals for potential applications, a brief review of organic cocrystals is presented here, including an introduction to organic cocrystals as well as discussions of cocrystal preparation, methods and techniques of characterization, and multifunctional applications of cocrystals. Moreover, the outlook for further studies and applications of cocrystal engineering is considered.

Many teachers believe that providing greater emotional and organizational supports in the beginning of the year strengthens their ability to teach effectively as the year progresses. Some interventions, such as the Responsive Classroom (RC) approach, explicitly embed this sequence into professional development efforts. We tested the hypothesis that earlier emotional and organizational supports set the stage for improved instruction later in the year in a sample of third- and fourth-grade teachers enrolled in a randomized controlled trial of the RC approach. Further, we examined the extent to which the model generalized for teachers using varying levels of RC practices as well as whether or not teachers were in the intervention or control groups. Teachers' emotional, organizational, and instructional interactions were observed using the Classroom Assessment Scoring System (Pianta, La Paro, & Hamre, 2008) on five occasions throughout the year. Results indicated a reciprocal relation between emotional and instructional supports. Specifically, higher levels of emotional support earlier in the year predicted higher instructional support later in the year. Also, higher levels of instructional support earlier in the year predicted higher emotional support later in the year. Classroom organization was not found to have longitudinal associations with the other domains across a year. This pattern was robust when controlling for the use of RC practices as well as across intervention and control groups. Further, teachers' use of RC practices predicted higher emotional support and classroom organization throughout the year, suggesting the malleability of this teacher characteristic. Discussion highlights the connection between teachers' emotional and instructional supports and how the use of RC practices improves teachers' emotionally supportive interactions with students.

Full Text Available The field of human resources requires the presence and action of several categories of persons and managerial structures interested in the quality of human resources and the activities developed by them. Besides managers and employees there are also the shareholders, the unions, the customers, the different national or local agencies, the local community, etc., with major interests regarding decisions in the human resources area. In order to harmonize their activities and achieve an optimal perspective within the evolution of Human Resource Management, special attention is paid to the strategy of human resources management. According to many specialists, strategies in the field of Human Resource Management show, in the first place, that personnel function adopts a broader perspective and a more dynamic view of human resources, which enables its full integration within the other functions of the organization. In the second place, strategies in the field of Human Resource Management designate the assembly of long term objectives concerning human resources, the main modalities of achieving them and the necessary resources which guarantee that the organization’s structure, value and culture as well as the utilization of its personnel contribute to fulfilling the general objectives of the organization. Therefore, we approached in this paper the problems of grounding and elaborating the Human Resource Management strategy, and we outlined their specific traits, as these are necessary aspects in order to emphasise at the end of our paper the correlation between the strategy in the field of Human Resource Management and the general strategy of the organization. Taking into account specialists and practitioners’ increased interest in knowing, substantiating and implementing strategies in the area of Human Resource Management, we consider that the aspects presented in this paper are modern issues and a starting pointing in solving the great problems of

Genetic diseases represent a significant public health challenge in China that will need to be addressed by a correspondingly large number of professional genetic counselors. However, neither an official training program for genetic counseling, nor formal board certification, was available in China before 2015. In 2009, a genetic counseling training program based on role-playing was implemented as a pilot study at the Third Military Medical University to train third-year medical students. Questionnaires on participant attitudes to the program and role-playing were randomly administered to 324 students after they had finished their training. Pre- and post-training instructional tests, focusing on 42 key components of genetic counseling, were administered randomly to 200 participants to assess mastery of each component. Finally, scores in final examinations of 578 participants from 2009 to 2011 were compared to scores obtained by 614 non-participating students from 2006 to 2008 to further assess program efficacy. Both the training program and the instructional strategy of role-playing were accepted by most participants. Students believed that role-playing improved their practice of genetic counseling and medical genetics, enhanced their communication skills, and would likely contribute to future professional performance. The average understanding of 40 of the key points in genetic counseling was significantly improved, and most students approached excellent levels of mastery. Scores in final examinations and the percentages of students scoring above 90 were also significantly elevated. Role-playing is a feasible and effective instructional strategy for training genetic counselors in China as well as in other developing countries.

During the last decade, the United States has lost competitive stature in the world. Challenged daily by a technically sophisticated and vitalized global economy, industry and Government are examining quality and productivity initiatives with which to meet the foreign competitive challenge. At stake are our quality of life and our standard of living for the remainder of this century and beyond. Being competitive is an ongoing process, tuned to an awareness and understanding of the dynamics of the world marketplace and to the changing nature of the work environment. Solutions to America's quality and productivity problems do not exist independently within any organization or industry or at any given level of society. Success depends on commitment, partnership, meshing of goals and responsibilities, mutual respect and understanding, and a desire to be first. A change in organizational management culture is required. Traditional authoritarian management practices must give way to enlightened leadership initiatives that stress employee involvement and participation. There must be a lessening of adversarial relationships between management and labor and between industry and Government. Quality and productivity are understood to be the end result of an integrated process which begins with vigorous, committed leadership and ends with a satisfied customer. The essential elements in the revitalization process are organized in this report into seven strategies which represent the major findings of the Second NASA Symposium on Quality and Productivity. Each strategy is then broken down into its principal themes which are presented as recommendations. No one strategy can stand apart from any other; all are interrelated and work together.

This study compared the effect of lecture-based instruction to that of problem-based instruction on learner performance (on near-transfer and far-transfer problems), problem solving processes (reasoning strategy usage and reasoning efficiency), and attitudes (overall motivation and learner confidence) in a Genetics course. The study also analyzed the effect of self-regulatory skills and prior-academic achievement on performance for both instructional strategies. Sixty 11th grade students at a public math and science academy were assigned to either a lecture-based instructional strategy or a problem-based instructional strategy. Both treatment groups received 18 weeks of Genetics instruction through the assigned instructional strategy. In terms of problem solving performance, results revealed that the lecture-based group performed significantly better on near-transfer post-test problems. The problem-based group performed significantly better on far-transfer post-test problems. In addition, results indicated the learners in the lecture-based instructional treatment were significantly more likely to employ data-driven reasoning in the solving of problems, whereas learners in the problem-based instructional treatment were significantly more likely to employ hypothesis-driven reasoning in problem solving. No significant differences in reasoning efficiency were uncovered between treatment groups. Preliminary analysis of the motivation data suggested that there were no significant differences in motivation between treatment groups. However, a post-research exploratory analysis suggests that overall motivation was significantly higher in the lecture-based instructional treatment than in the problem-based instructional treatment. Learner confidence was significantly higher in the lecture-based group than in the problem-based group. A significant positive correlation was detected between self-regulatory skills scores and problem solving performance scores in the problem

One hundred forty-six teens attending an urban maternity hospital's prenatal clinic completed a questionnaire designed to assist in the development of educational programs utilizing computer-assisted television instruction or interactive video. Ninety-five percent of the teens agreed that additional information about desirable health behaviors during pregnancy would be helpful. Forty-six percent preferred obtaining information from a health professional at the hospital. Although 90% said that the race of the narrator for a film show was unimportant, responses regarding racial preference corresponded to the racial distribution of participants. Seventy-six percent of the teens preferred the narrator to be younger than 35 years of age, and 54% preferred a female narrator. Race was associated with video game experiences, preferences about the narrator's age and race, and favorite television shows. Age was not associated with responses to any of the questions. Although only 19% had ever used a computer, 98% stated they would like to try a computer with assistance. More than half (55%) knew how to type and 83% had played video games; of those who had played video games, 93% said they enjoyed doing so. Eighty-three percent of the respondents always or sometimes enjoyed cartoons. Favorite television shows and cartoon characters were identified. The design implications of the teens' preferences to the development of instruction using computers coupled with other emerging technologies are discussed.

Full Text Available This study intends to find out the effect of teaching word meaning deriving strategies to EFL Students in Taiwan. The subjects were one class of the first year students attending a junior college in Taiwan. They were given a pre-test, which contained a passage, 10 vocabulary test items and 10 strategy questions. The researchers then began a two-month experiment. During the experimental period, the researcher, who was the instructor of the subjects, taught word meaning deriving strategies to students. The post-test, which was exactly the same as the pre-test, was given at the end of the experimental period. The results show significant differences of students' correct guessing rates and the strategy choice between the pre-test and the post-test. This suggests that it is worthwhile teaching EFL students word meaning deriving strategies.

During the fall of 2008 a web survey, designed to collect information about pedagogical knowledge and practices, was completed by a representative sample of 722 physics faculty across the United States (50.3% response rate). This paper presents partial results to describe how 20 potential predictor variables correlate with faculty knowledge about and use of research-based instructional strategies (RBIS). The innovation-decision process was conceived of in terms of four stages: knowledge versus no knowledge, trial versus no trial, continuation versus discontinuation, and high versus low use. The largest losses occur at the continuation stage, with approximately 1/3 of faculty discontinuing use of all RBIS after trying one or more of these strategies. Nine of the predictor variables were statistically significant for at least one of these stages when controlling for other variables. Knowledge and/or use of RBIS are significantly correlated with reading teaching-related journals, attending talks and workshops related to teaching, attending the physics and astronomy new faculty workshop, having an interest in using more RBIS, being female, being satisfied with meeting instructional goals, and having a permanent, full-time position. The types of variables that are significant at each stage vary substantially. These results suggest that common dissemination strategies are good at creating knowledge about RBIS and motivation to try a RBIS, but more work is needed to support faculty during implementation and continued use of RBIS. Also, contrary to common assumptions, faculty age, institutional type, and percentage of job related to teaching were not found to be barriers to knowledge or use at any stage. High research productivity and large class sizes were not found to be barriers to use of at least some RBIS.

This study identifies three distinct levels of text-image integration in page design in a linear relationship of lesser to greater integration: prose primary, prose subsumed, and fully integrated strategies. Science textbook pages were redesigned according to these holistic design strategies for 158 7th-grade students. There were three separate treatment tests, as well as a pre-test and post-test, and pilot tests with both undergraduate students and the subjects themselves. Subjects found the fully integrated strategy to produce the most visually interesting designs and the prose primary strategy to produce the least interesting, with prose subsumed definitively in between (according to 95% confidence intervals). The strategy employed significantly altered interest in science subject matter in one of three treatments (ANOVA, P=0.0446), where a Student's t-test revealed that the prose subsumed strategy produced higher interest in subject matter than prose primary. The strategy employed significantly altered comprehension of abstract relationships in one of three treatments (ANOVA, P=0.0202), where a Student's t-test revealed that the fully integrated strategy resulted in greater comprehension than prose primary. For the same treatment condition significant differences were found through ANOVA for factual-level knowledge (P=0.0289) but not conceptual-level knowledge ( P=0.0586). For factual-level knowledge prose primary resulted in lesser comprehension than both prose subsumed and fully integrated. Comprehension is defined according to cognitive load theory. No strategy impact on perception of task difficulty was found. This study was approved by North Carolina State University's Institutional Review Board and Wake County Public School System's Research Review Committee.

This research titled 'A Study to Determine Instructors Self-Reported Instructional Strategies Which Foster Science Literacy in an EFL (English as a Foreign Language) Environment' is an ethnographic study based on grounded theory principles and research design. The essence of the research was to answer five research questions that would ultimately create a foundation for instructional strategies allowing science instructors to foster science literacy in an EFL environment. The research attempts to conceptualize the research participants' instructional strategies that promote strong science literacy skills. Further to this, consider the complexities that this learning environment inherently offers, where the learning event is occurring in an English environment that is a second language for the learner. The research was designed to generate personal truths that produced common themes as it relates to the five research questions posed in this thesis; what instructional strategies do current post secondary science instructors at one College in Qatar believe foster science literacy in an EFL environment? As well, do science instructors believe that total immersion is the best approach to science literacy in an EFL environment? Is the North American model of teaching/learning science appropriate in this Middle Eastern environment? Are the current modes of teaching/instruction optimizing student's chances of success for science literacy? What do you feel are the greatest challenges for the EFL learner as it relates to science?

In this study, the authors examined the effects of the Teach-Model-Coach-Review instructional approach on caregivers' use of four enhanced milieu teaching (EMT) language support strategies and on their children's use of expressive language. Four caregiver-child dyads participated in a single-subject, multiple-baseline study. Children were between 24 and 42 months of age and had language impairment. Interventionists used the Teach-Model-Coach-Review instructional approach to teach caregivers to use matched turns, expansions, time delays, and milieu teaching prompts during 24 individualized clinic sessions. Caregiver use of each EMT language support strategy and child use of communication targets were the dependent variables. The caregivers demonstrated increases in their use of each EMT language support strategy after instruction. Generalization and maintenance of strategy use to the home was limited, indicating that teaching across routines is necessary to achieve maximal outcomes. All children demonstrated gains in their use of communication targets and in their performance on norm-referenced measures of language. The results indicate that the Teach-Model-Coach-Review instructional approach resulted in increased use of EMT language support strategies by caregivers. Caregiver use of these strategies was associated with positive changes in child language skills.
Full Text Available Metacognitive strategy instruction (MetSI has been shown to have a strong impact on various aspects of English as a second/foreign language instruction. The present study aimed to investigate the effect of MetSI on the improvement of listening selfefficacy among English-as-a-foreign-language (EFL learners. A group of sixty female undergraduate learners of English literature at a state-run university in Iran consented to take part in this study. After homogenizing the participants' English proficiency level using a sample section of the British Council IELTS test, 40 learners were selected whose English proficiency fell within intermediate to upperintermediate level. A listening self-efficacy questionnaire (borrowed from Rahimi and Abedini, 2009 was used to measure the participants’ level of listening selfefficacy in the pre and post-test phases of the study. The participants were randomly assigned to treatment (n=20 and control (n=20 groups. The treatment group received 8 hours of MetSI during eight sessions based on the model proposed by Vandergrift (2003 while the control group didn't receive any explicit MetSI. The control group received the usual training in listening instead.

The purpose of this study was to examine whether field-dependent/independent style awareness affects learning outcomes and learning strategies used in a hypermedia instructional module. Field-dependent/independent style was measured using the Global Embedded Figures Test. Style awareness meant that students were provided with information and explanations about their individual cognitive styles and the learning strategies that accommodate those styles. The study entailed examining students' achievement in a multiple-choice test and performance in a design task, and also their navigation patterns as they studied a science-oriented Webquest. The sample consisted of 149 eighth-grade students in 10 sections of a science class taught by two teachers in a public middle school. A two-group posttest-only design on one factor (style awareness) was used. Sixty-eight students in five sections of the class were assigned to the treatment group (field dependent/independent style awareness) while the other 81 students in five sections were assigned to the control group (no field dependent/independent style awareness). The study took place over a period of 6 days. On the first day, students in the treatment group were first tested and debriefed on their individual styles. Next, all students in both the treatment and control groups studied the hypermedia instructional module (Webquest) over a period of two days. On the fourth and fifth days students worked on the performance tasks, and on the sixth day students took the multiple-choice test and students in the control group were tested and debriefed on their individual styles. The findings indicate that style awareness significantly influenced the learning strategies of field-dependent students as they studied and carried out learning tasks in the Webquest. Field-dependent students with style awareness used hypertext links and navigated the menu sequentially a greater number of times than their counterparts with no style awareness
The United States Food and Drug Administration (FDA) Amendments Act of 2007 mandated that Risk Evaluation and Mitigation Strategies (REMS) be required of manufacturers. These REMS are strategies implemented to manage known or potential risks associated with drugs and to ensure ongoing pharmacovigilance throughout the life of a pharmaceutical product, including once the product becomes available as generic. The elements of an individual REMS program consist of three levels: medication guide or patient package insert, communication plan, and elements to assure safe use (ETASU). A medication guide or patient package insert is used to help prevent serious adverse events, aid in patient decision making, and enhance drug adherence. Communication plans are used to educate health care providers and to encourage their compliance with REMS. The ETASU is a restrictive process that is implemented when it is deemed necessary to ensure that patients have safe access to products with known serious risks that would otherwise be unavailable. To review the components of REMS and specifically assess their impact on health care providers practicing within the organ transplantation arena, a literature search of the MEDLINE database (January 2007-December 2010) was performed, and published materials from the FDA and its Web site were also reviewed. In transplantation, REMS programs exist for both everolimus (medication guide and communication plan) and sirolimus (medication guide). The FDA has stated that all mycophenolic acid derivatives will be subject to a proposed REMS that has not yet been approved; however, both branded mycophenolic acid agents already have approved medication guides. The REMS are a permanent fixture in the development and marketing of pharmaceutical agents, and their further implementation in solid organ transplantation is inevitable. Transplantation providers should take a proactive role in patient education and implementation of REMS within the therapeutic area

Sight-word instruction can be a useful supplement to phonics-based methods under some circumstances. Nonetheless, few studies have evaluated the conditions under which pictures may be used successfully to teach sight-word reading. In this study, we extended prior research by examining two potential strategies for reducing the effects of overshadowing when using picture prompts. Five children with developmental disabilities and two typically developing children participated. In the first experiment, the therapist embedded sight words within pictures but gradually faded in the pictures as needed using a least-to-most prompting hierarchy. In the second experiment, the therapist embedded text-to-picture matching within the sight-word reading sessions. Results suggested that these strategies reduced the interference typically observed with picture prompts and enhanced performance during teaching sessions for the majority of participants. Text-to-picture matching also accelerated mastery of the sight words relative to a condition under which the therapist presented text without pictures. © 2016 Society for the Experimental Analysis of Behavior.

Full Text Available This paper describes how management strategies in science learning are done by teachers in Islamic schools. This is motivated by the ranking of Indonesia which 87 percent of the population of Muslims always occupy the lowest position for the ability of science literacy. This research was conducted for four months using descriptive qualitative design with data collection technique of interview, observation and documentation. The subjects of the study were six Islamic schools in Lamongan, East Java. The six Islamic schools were chosen by purposive sampling. The results showed that the learning activities of science more dominated by teachers, students heard more explanation than the practice in verifying the process of science. The majority of teachers use lecture, question and answer methods, and assignments, and occasionally apply discussion and demonstration methods. Science laboratories in schools have not been maximally used, some have limited tools and materials, some of which lack laboratory space and even two schools without a science laboratory. Assessment of student learning progress done through pretest, posttest, daily test, question and answer during lessons, UTS and UAS. Teacher's strategy in managing student learning motivation by using animated video as apperception, integrating science materials with Islamic religious values.

Metal-Organic Frameworks (MOFs) represent an emerging new class of functional crystalline solid-state materials. In the early discovery of this now rapidly growing class of materials significant challenges were often encountered. However, MOFs today, with its vast structural modularity, reflected by the huge library of the available chemical building blocks, and exceptional controlled porosity, stand as the most promising candidate to address many of the overbearing societal challenges pertaining to energy and environmental sustainability. A variety of design strategies have been enumerated in the literature which rely on the use of predesigned building blocks paving the way towards potentially more predictable structures. The two major design strategies presented in this work are the molecular building block (MBB) and supermolecular building block (SBB) -based approaches for the rationale assembly of functional MOF materials with the desired structural features. In this context, we targeted two highly connected MOF platforms, namely rht-MOF and shp-MOF. These two MOF platforms are classified based on their topology, defined as the underlying connectivity of their respective net, as edge transitive binodal nets; shp being (4,12)-connected net and rht being (3,24)-connected net. These highly connected nets were deliberately targeted due to the limited number of possible nets for connecting their associated basic building units. Two highly porous materials were designed and successfully constructed; namely Y-shp-MOF-5 and rht-MOF-10. The Y-shp-MOF-5 features a phenomenal water stability with an exquisite behavior when exposed to water, positioning this microporous material as the best adsorbent for moisture control applications. The shp-MOF platform proved to be modular to ligand functionalization and thus imparting significant behavioral changes when hydrophilic and hydrophobic functionalized ligands were introduced on the resultant MOF. On the other hand, rht

A literature search revealed very little information on how to teach working engineers, which became the motivation for this research. Effective training is important for many reasons such as preventing accidents, maximizing fuel efficiency, minimizing pollution emissions, and reducing equipment downtime. The conceptual framework for this study included the development of a new instructional design framework called the Multimedia Cone of Abstraction (MCoA). This was developed by combining Dale's Cone of Experience and Mayer's Cognitive Theory of Multimedia Learning. An anonymous survey of 118 engineers from a single Midwestern manufacturer was conducted to determine their demographics, learning strategy preferences, verbal-visual cognitive styles, and multimedia preferences. The learning strategy preference profile and verbal-visual cognitive styles of the sample were statistically significantly different than the general population. The working engineers included more Problem Solvers and were much more visually-oriented than the general population. To study multimedia preferences, five of the seven levels in the MCoA were used. Eight types of multimedia were compared in four categories (types in parantheses): text (text and narration), static graphics (drawing and photograph), non-interactive dynamic graphics (animation and video), and interactive dynamic graphics (simulated virtual reality and real virtual reality). The first phase of the study examined multimedia preferences within a category. Participants compared multimedia types in pairs on dual screens using relative preference, rating, and ranking. Surprisingly, the more abstract multimedia (text, drawing, animation, and simulated virtual reality) were preferred in every category to the more concrete multimedia (narration, photograph, video, and real virtual reality), despite the fact that most participants had relatively little prior subject knowledge. However, the more abstract graphics were only slightly

Researchers are increasingly interested in working memory (WM) training. However, it is unclear whether it strengthens comprehension in young children who are at risk for learning difficulties. We conducted a modest study of whether the training of verbal WM would improve verbal WM and passage listening comprehension and whether training effects differed between two approaches: training with and without strategy instruction. A total of 58 first-grade children were randomly assigned to three groups: WM training with a rehearsal strategy, WM training without strategy instruction, and controls. Each member of the two training groups received a one-to-one, 35-min session of verbal WM training on each of 10 consecutive school days, totaling 5.8 hr. Both training groups improved on trained verbal WM tasks, with the rehearsal group making greater gains. Without correction for multiple group comparisons, the rehearsal group made reliable improvements over controls on an untrained verbal WM task and on passage listening comprehension and listening retell measures. The no-strategy-instruction group outperformed controls on passage listening comprehension. When corrected for multiple contrasts, these group differences disappeared but were associated with moderate to large effect sizes. Findings suggest-however tentatively-that brief but intensive verbal WM training may strengthen the verbal WM and comprehension performance of young children at risk. Necessary caveats and possible implications for theory and future research are discussed. © Hammill Institute on Disabilities 2015.

Full Text Available In this article we analyse professional police and community policing in view of professionalism, strategy and structures. We aim to find ways for synthesizing these models that are usually seen as incompatible. Unlike many earlier studies of police organizations or strategies, we view strategies in the organization at the corporate, functional and operational levels, and argue that by combining them with functional and divisional principles of structuring, it is possible to place professional strategy at the core of policing, while using the community policing strategy mainly as a component part of the strategy in the framework of divisional organization. This way it is possible to avoid the risk of alienating police from the community and to ensure the successful implementation of corporate strategy through providing professional police units that perform the narrow functions, with quick and adequate information from the community.

Full Text Available This article revisits the cognitive load theory to explore the use of worked examples to teach a selected topic in a higher level undergraduate physics course for distance learners at the School of Distance Education, Universiti Sains Malaysia. With a break of several years from receiving formal education and having only minimum science background, distance learners need an appropriate instructional strategy for courses that require complex conceptualization and mathematical manipulations. As the working memory is limited, distance learners need to acquire domain specific knowledge in stages to lessen cognitive load. This article charts a learning task with a lower cognitive load to teach Fermi-Dirac distribution and demonstrates the use of sequential worked examples. Content taught in stages using worked examples can be presented as a form of didactic conversation to reduce transactional distance. This instructional strategy can be applied to similar challenging topics in other well-structured domains in a distance learning environment.

Full Text Available Knowledge management plays an important role on the success of organizations but there are several reasons that many organizations fail to talk a full advantage of the benefits of knowledge management implementation. In this paper, we perform an empirical investigation on supreme audit court organization of Iran. The survey uses a standard questionnaire and distributes 116 questionnaires among 228 people who worked for this organization. Cronbach alpha yields 0.817, which is well above the minimum acceptable level. Kolmogorov–Smirnov test has been performed to examine the normality of the data and yields 1.71 for management attributes, 1.78 is for resource factors and 1.73 for environment factors and P-value for all three factors is 0.000. The preliminary results of our survey indicate that management is the first important factor followed by resources and environment factors.

This report describes a logical approach to resolving potential safety issues resulting from the presence of organic components in hanford tank wastes. The approach uses a structured logic diagram (SLD) to provide a pathway for quantifying organic safety issue risk. The scope of the report is limited to selected organics (i.e., solvents and complexants) that were added to the tanks and their degradation products. The greatest concern is the potential exothermic reactions that can occur between these components and oxidants, such as sodium nitrate, that are present in the waste tanks. The organic safety issue is described in a conceptual model that depicts key modes of failure-event reaction processes in tank systems and phase domains (domains are regions of the tank that have similar contents) that are depicted with the SLD. Applying this approach to quantify risk requires knowing the composition and distribution of the organic and inorganic components to determine (1) how much energy the waste would release in the various domains, (2) the toxicity of the region associated with a disruptive event, and (3) the probability of an initiating reaction. Five different characterization options are described, each providing a different level of quality in calculating the risks involved with organic safety issues. Recommendations include processing existing data through the SLD to estimate risk, developing models needed to link more complex characterization information for the purpose of estimating risk, and examining correlations between the characterization approaches for optimizing information quality while minimizing cost in estimating risk

Early brain patterning depends on proper arrangement of positional information. This information is given by gradients of secreted signaling molecules (morphogens) detected by individual cells within the responding tissue, leading to specific fate decisions. Here we report that the morphogen FGF8 exerts initially a differential signal activity along the E9.5 mouse neural tube. We demonstrate that this polarizing activity codes by RAS-regulated ERK1/2 signaling and depends on the topographical location of the secondary organizers: the isthmic organizer (IsO) and the anterior neural ridge (anr) but not on zona limitans intrathalamica (zli). Our results suggest that Sprouty2, a negative modulator of RAS/ERK pathway, is important for regulating Fgf8 morphogenetic signal activity by controlling Fgf8-induced signaling pathways and positional information during early brain development.

Full Text Available This study investigated the student performance in an inquiry learning course which integrated information literacy and reading strategies in a fourth-grade science class. The curriculum design was based on the Big6 model, which includes the stages of task definition, information seeking strategies, location & access, use of information, synthesis, and evaluation. The study duration was one semester. The data was gathered through participant observations, interviews, surveys, tests, and from documents generated in the course implementation. The results showed that the integration of information literacy and reading strategies instruction was feasible. The students performed well in information seeking strategies, locating & accessing information, using and synthesizing information. In contrast, their abilities in task definition and evaluation needed further improvement. Also, while the students did acquire various reading strategies during the inquiry process, they needed more exercises to internalize the skills. The performance on the acquisition of subject knowledge was also improved through the inquiry learning. The participating instructors considered that the collaboration between teachers of different subject matters was the key to a successful integrated instruction [Article content in Chinese

Full Text Available The paper discusses the relationship between different types of human resource management (HRM strategy and the human resource outsourcing, and impact on the size of human resource (HR department. Three HRM strategies are considered: Facilitation, accumulation and utilization. The data for the study were obtained from survey responses from 232 organizations, of which 113 were engaged in HR outsourcing. The findings suggest that organizations tend to rely on outsourcing of HR functions when they espouse facilitation and utilization HRM strategy. Concurrently, by relying on HR outsourcing, the organizations manage to experience a reduction in the size of HR department. The results show that it is important for the organizations to better understand the implications of an increased reliance on outsourcing within HR. This allows them to focus on how HR functions are delivered within organizations with the interaction of HRM strategy and the size of HR department will tend to be smaller resulting from outsourcing activities.

Postoperative organ failure is a challenging disease process that is better prevented than treated. Providers should use close observation and clinical judgment, and checklists of best practices to minimize the risk of organ failure in their patients. The treatment of multiorgan dysfunction syndrome (MODS) generally remains supportive, outside of rapid initiation of source control (when appropriate) and targeted antibiotic therapy. More specific treatments may be developed as the complex pathophysiology of MODS is better understood and more homogenous patient populations are selected for study. Copyright Â© 2012 Elsevier Inc.

The aim of this study was to highlight recent evidence on important aspects of influenza vaccination in solid organ transplant recipients. Influenza vaccine is the most evaluated vaccine in transplant recipients. The immunogenicity of the vaccine is suboptimal after transplantation. Newer formulations such as inactivated unadjuvanted high-dose influenza vaccine and the administration of a booster dose within the same season have shown to increase response rates. Intradermal vaccination and adjuvanted vaccines did not show clear benefit over standard influenza vaccines. Recent studies in transplant recipients do not suggest a higher risk for allograft rejection, neither after vaccination with a standard influenza vaccine nor after the administration of nonstandard formulation (high-dose, adjuvanted vaccines), routes (intradermally) or a booster dose. Nevertheless, influenza vaccine coverage in transplant recipients is still unsatisfactory low, potentially due to misinterpretation of risks and benefits. Annual influenza vaccination is well tolerated and is an important part of long-term care of solid organ transplant recipients.

Organic semiconducting materials based on polymers and molecular systems containing an electronically delocalized structure are the basis of emerging optoelectronic technologies such as plastic solar cells and flexible transistors. For isolated molecules, guidelines exist that rely on the molecular formula to tailor the frontier (highest occupied or lowest unoccupied) molecular orbital energy levels and optical absorption profiles. Much less control can be achieved over relevant properties, however, as one makes the transition to the ensemble behaviour characteristic of the solid state. Polymeric materials are also challenging owing to the statistical description of the average number of repeat units. Here we draw attention to the limitations of molecular formulae as predictive tools for achieving properties relevant to device performances. Illustrative examples highlight the relevance of organization across multiple length scales, and how device performances--although relevant for practical applications--poorly reflect the success of molecular design.

Vegetation which enhances in-situ biodegradation of organic compounds can play a key role in the bioremediation of such contaminants in polluted soils and groundwater. Plants may act directly on some contaminants by degrading them, but their main effect is to enhance microbial populations in the thizosphere. Microbially mediated transformations are thus indirectly facilitated by root exudates which nourish the indigenous microorganisms. Plants may also be viewed as a solar driven pump-and-treat system which can contain a plume and reduce the spread of contaminated water. Laboratory investigations carried out in a growth chamber with alfalfa plants provide evidence for the (microbially mediated) biodegradation of organic compounds such as toluene, phenol and TCE. Alfalfa plants tolerate concentrations of these organics in contaminated water up to 100 mg/L. They facilitate transfer of the contaminants from the saturated to the vadose zone. For volatile organic compounds such as TCE, vegetation provides a controlled release of compounds and hence assures dilution of the TCE evapotranspired into the atmosphere from contaminated soils. Using a range of calculated plausible scenarios, it is shown that intermedia transfer caused by volatilization associated with plants is most unlikely to lead to exceedance of standards for gas phase contamination, for most volatile contaminants. Possible action level exceedances might occur with highly toxic substances including vinyl chloride and carbon tetrachloride, if they re present in ground water at levels above kilogram amounts in a single plume of a few hectares, and released by vigorously growing plants under hot dry conditions. Information needed for the calculation and design of plant-based bioremediation systems for typical sites is discussed in this paper.

The main aim of this report is to present a picture of the current organization of nephrology in Spain. The Spanish health system offers almost universal coverage, a wide variety of services and a high-quality network of hospitals and primary care centers. Spain has a specialized health care training system that is highly developed, highly regulated, with the capacity to provide high-quality training in 54 different specialties. Nephrology is basically a hospital-based specialty. There are no private dialysis patients in Spain. Hemodialysis centers are 40% public, 15% private and 45% run by companies. The National Health System covers 95% of the population, and there is no cost to patients for treatment of renal disease (dialysis and transplant). We observed a clear decrease of nephrology in residents' election rankings, with position 29 out of 47 specialties in 2007. Some of the reasons for this are the complexity of the subject, no clear information at the university, reduction of professional posts and a very good public service with minimal private practice. In Spain, a model of organization for transplantation was adopted based on a decentralized transplant coordinating network. For cadaveric donors, it compares favorably with rates in other Western countries. Living donor transplantation is very low in Spain--just 10% of total renal transplantation activity. New programs due to financial constraints need to include reduced dialysis costs, greater cost-effectiveness of prescriptions, better handling of ethical issues related to the need for using a clinical score of chronic kidney disease patients to make decisions about conservative or renal replacement therapy and an action plan for improvement of organ donation and transplantation. Recovery of skills (acute kidney injury, biopsies, vascular access, etc.), research and advances in autonomous activities (imaging, surgical and medical vascular training, etc.) are some of the future educational paths needed in

The power conversion efficiency of organic photovoltaic (OPV) cells has been rapidly improved during the last few years and currently reaches around 10 %. The performance is evenly governed by absorption, exciton diffusion, exciton dissociation, carrier transfer, and collection efficiencies. Establishing a better understanding of OPV device physics combined with the development of new materials for each executive step contributes to this dramatic improvement. This dissertation focuses mainly on material design and development to correlate the intrinsic properties of organic semiconductors and the OPV performance. The introductory Chapter 1 briefly reviews the motivation of OPV research, its working mechanism, and representative organic materials for OPV application. Chapter 2 discusses the modulation of conjugated polymer's (CP's) absorption behavior and an efficient semi-empirical approach to predict CP's energy levels from its constituent monomers' HOMO/LUMO values. A strong acceptor lowered both the HOMO and LUMO levels of the CP, but the LUMO dropped more rapidly which ultimately produced a narrowed band-gap in the electron donating/accepting alternating copolymer system. In addition, the energy level difference between the CP and the constituent monomers converged to a constant value, providing an energy level prediction tool. Chapter 3 illustrates the systematic investigation on the relationship between the molecular structure of an energy harvesting organic dye and the exciton dissociation efficiency. The study showed that the quantum yield decreased as the exciton binding energy increases, and dipole moment direction should be properly oriented in the dye framework in order to improve photo-current generation when used in a dye sensitized photovoltaic device. Chapter 4 demonstrates the ultrasonic-assisted self-assembly of CPs in solution, rapidly and efficiently. Ultrasonication combined with dipolar media accelerated CP's aggregation, and the effect of CP

Introduction Pre-menopause in women presents with diverse symptoms, encompassing the tri-dimensional spheres of physical, social and psychological domains, which requires development of appropriate coping strategies to overcome these problems. Aim To assess level of knowledge about tri-dimensional problems in pre-menopausal women and evaluate effectiveness of self instruction module on coping strategies of these problems by pre-test and post-test analysis. Materials and Methods In a cross-sectional, community based study, in pre-menopausal women aged 40-49years baseline knowledge of tridimensional problems was assessed in 300 pre-menopausal women, selected by convenient sampling after satisfying selection criteria, by a pre-formed questionnaire. This was followed by administration of a pre-tested, Self-Instructional Module (SIM). The SIM dealt with imparting knowledge about coping strategies regarding pre-menopausal problems and the participants were required to read and retain the SIM. Post-test was conducted using same questionnaire after seven days. Statistical Analysis Chi-square test/ Paired t-test was used for comparing ratios. A ‘p-value’ <0.05 was considered statistically significant. Results Baseline knowledge of tridimensional problems was adequate in 10%, moderate in 73% and inadequate in 17% women with a pre-test mean knowledge score of 8.66±2.45. The post-test mean knowledge score was higher (19.11±3.38) compared to the pre-test score. The post-test mean knowledge difference from pre-test was -10.45 with a highly significant paired t-value of -47.45 indicating that the self-instructional module was effective in increasing the knowledge score of pre- menopausal women under study. Conclusion Administration of self instructional module was shown to significantly increase the knowledge scores in all areas of pre-menopausal tri-dimensional problems. Such self-instructional module can be used as an effective educational tool in increasing the knowledge

Productivity among organ procurement organizations varies widely in the US, and the pressure to determine critical success factors increases as the organ pool shrinks and managed care expands. This study compared three successful organ procurement organizations, identified commonalities among them in cost of doing business, and examined direct and indirect expenses, staffing, specialized requestor programs, and professional and public education programs. The three organ procurement organizations were chosen because of their performance in terms of donors per million population, complexity, and size. The following key indicators were compared and analyzed: annual operating budget, size and composition of staff, funds and resources invested in professional education versus public education, tissue recovery operations, results of minority initiatives, and employee compensation programs.
A Waste Tank Organic Safety Program (Program) Plan is to be transmitted to the U.S. Department of Energy, Richland Operations Office (RL) for approval by December 31, 1993. In April 1993 an agreement was reached among cognizant U.S. Department of Energy - Headquarters (HQ), RL and Westinghouse Hanford Company (WHC) staff that the Program Plan would be preceded by a ''Corrective Action Strategy,'' which addressed selected planning elements supporting the Program Plan. The ''Corrective Action Strategy'' would be reviewed and consensus reached regarding the planning elements. A Program Plan reflecting this consensus would then be prepared. A preliminary ''corrective action strategy'' is presented for resolving the organic tanks safety issue based on the work efforts recommended in the ISB (Interim Safety Basis for Hanford Site tank farm facilities). A ''corrective action strategy'' logic was prepared for individual SSTs (single-shell tanks), or a group of SSTs having similar characteristics, as appropriate. Four aspects of the organic tanks safety issue are addressed in the ISB: SSTs with the potential for combustion in the tank's headspace; combustion of a floating organic layer as a pool fire; surface fires in tanks that formerly held floating organic layers; SSTs with the potential for organic-nitrate reactions. A preliminary ''corrective action strategy'' for each aspect of the organic tanks safety issue is presented

Hepatitis A virus (HAV) is a positive-strand RNA virus classified in the genus Hepatovirus of the family Picornaviridae It is an ancient virus with a long evolutionary history and multiple features of its capsid structure, genome organization, and replication cycle that distinguish it from other mammalian picornaviruses. HAV proteins are produced by cap-independent translation of a single, long open reading frame under direction of an inefficient, upstream internal ribosome entry site (IRES). Genome replication occurs slowly and is noncytopathic, with transcription likely primed by a uridylated protein primer as in other picornaviruses. Newly produced quasi-enveloped virions (eHAV) are released from cells in a nonlytic fashion in a unique process mediated by interactions of capsid proteins with components of the host cell endosomal sorting complexes required for transport (ESCRT) system.

Full Text Available The new geopolitical reality that resulted from the dissolution of the USSR created the conditions for the establishment of the Shanghai Cooperation Organisation (SCO in 2001. The successful settlement of border issues between Russia and Kazakhstan, Kirgizstan and Tajikistan as well as with China also facilitated the process. With Uzbekistan joining the “Shanghai Five,” a new regional organization emerged. The SCO’s priorities were in the security sphere and the fight against the proliferation of drugs, illegal migration and organized crime, given the requirements of the times and the specific regional situation (including that in Afghanistan. As one of the active founders, Russia has always taken a leading role in the SCO’s organizational, political and legal formation, including setting specific trends and forms of cooperation, taking common measures, and holding events. During its presidency in 2008–2009 and 2014–2015, Moscow made additional efforts to strengthen cooperation among the SCO members in meeting new regional security challenges and to agree on coordinated positions on the key issues on the international and regional agenda. To increase the SCO’s credibility and political significance, Moscow emphasized its expansion, particularly with regard to the Eurasian Economic Union and the Silk Road Economic Belt. With global political and economic development growing more complicated, in order to revitalize Russia’s role in the SCO it is necessary to strengthen cooperation with China. The strategic character of bilateral relations reaffirmed at the Russian-Chinese summit in the summer of 2016 set a solid foundation.

Full Text Available Organizational knowledge has always been an important subject, but in the last years this issue has acquired a greater importance, due to factors like the development of information technologies, scientific advances and global competition, among others. Knowledge management goes beyond the identification, creation, sharing and use of knowledge within organizations; a new approach is to exchange and share experience and knowledge between organizations. The objective of this article is to present the importance of knowledge clusters as a structure and strategy to facilitate knowledge management between organizations associated to specific and interconnected sectors by common and complementary practices. According to the developed expositions and shown evidences of success in this work, it is possible to conclude that knowledge clusters represent a good strategy to manage knowledge among organizations as well as a competitiveness improvement strategy.

Studies indicate that many teachers have negative beliefs about science, which translates into low teacher efficacy, resulting in avoidance of science teaching or in ineffective science teaching behaviors. Highly efficacious teachers have been found to be more likely to use inquiry and student-centered teaching strategies, while teachers with a low sense of science-teaching efficacy are more likely to use teacher-directed strategies, such as didactic lectures and reading from the textbook (Czemiak, 1990). The purpose of this study was to investigate preservice science teachers' science-teaching self-efficacy changes and their correlation to teaching environment factors during the student teaching semester. Moreover, it explains how teaching environment factors and preservice teachers' science-teaching self-efficacy beliefs may relate to their use of teaching strategies in the science classroom during their student teacher training at teachers' colleges in Saudi Arabia. The population of this study is consisted of 184 middle and elementary preservice science teachers who were doing their student teaching at nine teachers' colleges (i.e., teachers' colleges of Riyadh, Dammam, Alrras, Almadinah, Alihsa, Jeddah, Makah, Altaief, and Abha) in Saudi Arabia during the spring semester of 2005. Three instruments were used to collect data for this study: (1) to measure science teaching self-efficacy, the researcher adapted the Science Teaching Efficacy Belief Instrument form B designed specifically for preservice teachers (STEBI-B); (2) to measure the school environment, the researcher adapted the Organizational Health Inventory (OHI), developed by Hoy, Tarter & Kottkamp (1991); and (3) to measure the type and frequency of instructional strategies that preservice science teachers use in the classroom, the researcher adapted the teaching practice subscale from The Local Systemic Change through Teacher Enhancement Science K-8 Teacher Questionnaire (Horizon Research, Inc., 2000

Organizers are regions of the embryo that can both induce new fates and impart pattern on other regions. So far, surprisingly few organizers have been discovered, considering the number of patterned tissue types generated during development. This may be because their discovery has relied on transplantation and ablation experiments. Here we describe a new approach, using chick embryos, to discover organizers based on a common gene expression signature, and use it to uncover the anterior intestinal portal (AIP) endoderm as a putative heart organizer. We show that the AIP can induce cardiac identity from non-cardiac mesoderm and that it can pattern this by specifying ventricular and suppressing atrial regional identity. We also uncover some of the signals responsible. The method holds promise as a tool to discover other novel organizers acting during development.

The purpose of this study is to propose a strategy for organ reconstruction in fluorescence molecular tomography (FMT) without prior information from other imaging modalities, and to overcome the high cost and ionizing radiation caused by the traditional structural prior strategy. The proposed strategy is designed as an iterative architecture to solve the inverse problem of FMT. In each iteration, a short time Fourier transform (STFT) based algorithm is used to extract the self-prior information in the space-frequency energy spectrum with the assumption that the regions with higher fluorescence concentration have larger energy intensity, then the cost function of the inverse problem is modified by the self-prior information, and lastly an iterative Laplacian regularization algorithm is conducted to solve the updated inverse problem and obtains the reconstruction results. Simulations and in vivo experiments on liver reconstruction are carried out to test the performance of the self-prior strategy on organ reconstruction. The organ reconstruction results obtained by the proposed self-prior strategy are closer to the ground truth than those obtained by the iterative Tikhonov regularization (ITKR) method (traditional non-prior strategy). Significant improvements are shown in the evaluation indexes of relative locational error (RLE), relative error (RE) and contrast-to-noise ratio (CNR). The self-prior strategy improves the organ reconstruction results compared with the non-prior strategy and also overcomes the shortcomings of the traditional structural prior strategy. Various applications such as metabolic imaging and pharmacokinetic study can be aided by this strategy.

Full Text Available This case study traces the evolution of library assignments for biological science students from paper-based workbooks in a blended (hands-on workshop to blended learning workshops using online assignments to online active learning modules which are stand-alone without any face-to-face instruction. As the assignments evolved to adapt to online learning supporting materials in the form of PDFs (portable document format, screen captures and screencasting were embedded into the questions as teaching moments to replace face-to-face instruction. Many aspects of the evolution of the assignment were based on student feedback from evaluations, input from senior lab demonstrators and teaching assistants, and statistical analysis of the students’ performance on the assignment.

This exploratory study examined three instructional strategies used with female high school biology students. The relative contributions of the strategies to student understanding of microbiology and motivation in science were analyzed. The science education community targeted underachievement in science by implementing changes in content and practices (NRC, 1996). Research suggested that teachers facilitate learnirig environments based on human constructivism (Mintzes, Wandersee, & Novak, 1997) that is rooted in meaningful learning theory (Ausubel, Novak & Hanesian, 1978). Teachers were advised to use both visual and verbal instructional strategies (Paivio, 1983) and encourage students to construct understandings by connecting new experiences to prior knowledge. The American Society for Microbiology supports the study of microorganisms because of their prominence in the biosphere (ASK 1997). In this study, two participating teachers taught selected microbiology concepts while focused on the cutting edge science of biofilms. Biology students accessed digitized biofilm images on an ASM web page and adapted them into products, communicated with biofilm researchers, and adapted a professional-quality instructional video for cross-age teaching. The study revealed improvements in understanding as evidenced on a written test; however, differences in learnirig outcomes were not significant. Other data, including student journal reflections, observations of student interactions, and student clinical interviews indicate that students were engaged in cutting edge science and adapted biofilm images in ways that increased understanding of microbiology (with respect to both science content and as a way of knowing) and motivation. An ASM CD-ROM of the images did not effectively enhance learning and this study provides insights into what could make it more successful. It also identifies why, in most cases, students' E-mail communication with biofilm researchers was unsuccessful

We investigated protection strategies of organs at risk (OARs) in intensity modulated radiation therapy (IMRT). These strategies apply to delivery of IMRT to moving body anatomies that show relative displacement of OAR in close proximity to a tumor target. We formulated an efficient genetic algorithm which makes it possible to search for global minima in a complex landscape of multiple irradiation strategies delivering a given, predetermined intensity map to a target. The optimal strategy was investigated with respect to minimizing the dose delivered to the OAR. The optimization procedure developed relies on variability of all parameters available for control of radiation delivery in modern linear accelerators, including adaptation of leaf trajectories and simultaneous modification of beam dose rate during irradiation. We showed that the optimization algorithms lead to a significant reduction in the dose delivered to OAR in cases where organs at risk move relative to a treatment target.

Despite efforts to dispel discrimination, workplace discrimination still occurs. We introduce two classes of identity management strategies individuals use to mitigate the negative consequences of discrimination: identity switching (i.e., deemphasizing target identities and recategorizing to a more positively valued identity) and identity redefinition (i.e., stereotype reassociation and regeneration). Organizations adopting a color-blind approach may make it more difficult for individuals to use identity switching because the policies deemphasize differences in social identities. In contrast, organizations adopting a multicultural approach may make it more difficult for individuals to use identity redefinition. Multicultural approaches, applied superficially, may celebrate group differences that might actually reinforce culturally dominant stereotypes. We explore the likelihood that individuals will adopt each strategy given these organizational approaches to diversity. We outline steps organizations can take to reduce the need for identity management strategies and to facilitate identity management when necessary.

ABSTRACT Soils play a key role in the Earth System (Keesstra et al., 2012; Brevick et al., 2015). Soils are a key resource for the human societies (Mol and Keesstra, 2012) and they are relevant to achieve the sustainability such as the United Nations Goals highlight (Keesstra et al., 2016). Agriculture soils, especially those under conventional tillage, are prone to organic matter mineralization, soil erosion, compaction and increase of greenhouse gases emission (Novara et al., 2011; Bruun et al., 2015; de Moraes et al., 2015; Choudhury et al., 2016; del Mar et al., 2016). The adoption of organic farming and sustainable management practices may provide a sustainable crop productivity, and in the meanwhile mitigate the negative impact of agriculture on ecosystem services benefits (Laudicina et al., 2015; Parras-Alcantara et al., 2015; 2016). The aim of this study was to examine, under field conditions, the long-term changes of soil organic matter under organic farming management in citrus orchards in Mediterranean environment and evaluate the ecosystem service on C sequestration in terms of economic benefits. The research was carried out at the Alcoleja Experimental Station located in the Cànyoles river watershed in the Eastern Spain on 45year old citrus plantation. Soil Organic Matter (SOM) content was monitored for 20 years at 6 different soil depth. The profitability of citrus plantation was estimated under conventional and organic management. Results showed that SOM in the 0-30 cm soil depth was the double after 20 years of organic farming management, ranging from 0.8 g kg-1 in 1995 to 1.5 g kg-1 in 2006. The highest SOM increase was in the top soil layer (368% of SOM increase in comparison to the initial SOM content) and decreased with soil depth. The effect of organic farming was relevant after 5 years since land management change, indicating that in Mediterranean environment the duration of long term studies should be higher than five years and proper policy

Research in order that artificial organs can supplement or completely replace the functions of impaired or damaged tissues and internal organs has been underway for many years. The recent clinical development of implantable left ventricular assist devices has revolutionized the treatment of patients with heart failure. The emerging field of regenerative medicine, which uses human cells and tissues to regenerate internal organs, is now advancing from basic and clinical research to clinical application. In this review, we focus on the novel biomaterials, i.e., fusion protein, and approaches such as three-dimensional and whole-organ tissue engineering. We also compare induced pluripotent stem cells, directly reprogrammed cardiomyocytes, and somatic stem cells for cell source of future cell-based therapy. Integrated strategy of artificial organ and tissue engineering/regenerative medicine should give rise to a new era of medical treatment to organ failure.
Full Text Available In organic horticultural systems, cover crops could provide several ecological services, therefore, they can be defined agroecological service crops (ASCs. The objective of this two-year research was to study the suitability on melon production of different ASC termination strategies, in combination with organic fertilisers application. In a split-block design, the main-plot was the ASC management, comparing: i green manure, in which the vetch was chopped and plowed into the soil; and ii roller-crimper (RC, in which the vetch was flattened by a roller-crimper; with iii fallow control, without vetch. The subplot consisted of offfarm organic inputs: i commercial humified fertiliser; ii anaerobic digestate fertiliser; iii composted municipal solid wastes; which were compared to iv unfertilised control (N0. At vetch termination, above soil biomass and nitrogen (N content were determined. At harvesting, crop yield performance and quality, N status and N efficiency were investigated. Also, main soil characteristics were assessed at the end of the trial. Among the ASC managements, the slightly reduced yield in the RC plots particularly in combination with N0 might have been the result of less N supplied by the vetch during the melon cycle. Anyway, no negative effects were observed for yield quality. The use of the RC showed a great potential in enhancing soil fertility. Our study suggests the suitability in organic farming of properly matching management of ASC and fertilisation strategies on melon crop.

Veterinary students are challenged to develop new, nonlinear ways of thinking as they learn diagnostic reasoning skills. To support this process, we use real-life cases in our clinical pathology course. Changes in student perceptions regarding the use of cases and changes in study strategies over time have not been previously investigated or compared to student grades. Students participated in three voluntary online surveys that included 4-point Likert scale questions and open-ended questions on the helpfulness of cases for learning and study strategies used during the course. We used Friedman tests to detect any differences in perceptions over time; McNemar's test and "Wilcoxon signed-rank tests were used to detect any differences in study strategies over time. Fisher's exact tests'were used to examine the association between the Likert scale responses and grades in quartiles. Before beginning the course, 29% of students responded that cases were very helpful to their learning, with similar "responses for helpfulness in applying course material and grasping important concepts. There was a significant trend of increasing positivity over the duration of the course, with 74% responding that cases were very helpful at the end of the course. The most-reported study strategy was working individually on cases before the midterm (74% of students), and the most helpful study strategy was attending class regularly (88% reported it as very "helpful). Study strategies did not change significantly over time. Overall, perceptions and study strategies did not vary significantly with grades.

Methods of organizing a big information retrieval system are discribed. A special attention is paid to the file organization. An adapting file structure is described in more detail. The discussed method gives one the opportunity to organize large files in such a way that the response time of the system can be minimized, when the file is increasing. In connection with the retrieval strategy a method is proposed, which uses the frequencies of the descr/iptors and the couples of the descriptors to forecast the expected number of the relevant documents. Programmes are made, on the base of these methods, which are used in the information retrieval systems of JINR

Combined strategies to control antinematicidal -resistant gastrointestinal nematodes in small ruminants on organized farms in Pakistan Antinematicidal resistance has been rooted on all the continents particularly in areas where ovine and caprine are being reared intensively due to frequent annual use of broad-spectrum dewormers. Farmers rely on mono-strategic scheme by using synthetic drugs to treat their livestock which is deemed the easier way to control gastrointestinal nematode infections as compared to the other strategies. On the other hand, recurrent employment of antinematicidal chemotherapeutics has conduced to development and prevalence of resistance among nematode populations. In this regard, other advocating strategies such as grazing management, rotation of antinematicidal drugs (although it is too late), amelioration of animal immunity, genetic approaches, biological control, nutritional supplementation, avoidance of mass treatment, improvement of management, eradication of concurrent diseases, and phytotherapy should be considered too. Although, by far there are no commercialized substantial alternatives to chemotherapy, but the current substitutes could decrease the parasitic burden, which, in turn, restrict indiscriminate use of synthetic drugs. The resistance is more rampant on organized farms as compared to non organized farms in rural areas in Asian, African and South Latin American countries because tamed animal raisers in those areas depend on ethnobotanicals to treat parasitism due to high cost of allopathic drugs. Therefore, in this review, the different strategies to control the antinematicidal resistance on organized farms in Pakistan will be elaborated. (author)

However, the scarcity of organs appropriate for transplantation has led to an organ shortage crisis. This article retrospectively reviews strategies to change negative public attitudes toward organ donation in the People's Republic of China.

The Dutch version of A Matter of Balance (AMB-NL) is a cognitive behavioral group program to reduce fear of falling and related activity avoidance in community-living older persons. This paper presents the strategy for implementation of AMB-NL in Dutch homecare organizations and the outcomes of this implementation. The aim was to implement AMB-NL in at least 50 % of 64 homecare organizations in The Netherlands in 2009 and 2010. The implementation strategy was based on the four phases of the Replicating Effective Interventions: pre-conditions, pre-implementation, implementation, and maintenance and evolution. After preparing the implementation activities, such as identifying implementation barriers, consulting stakeholders, preparing the materials involved in the implementation, and training the facilitators of the program (n = 53), AMB-NL was implemented in 16 of the 64 homecare organizations (25 %). Another five homecare organizations indicated that they would shortly include AMB-NL in their care program. These organizations conducted the intervention 19 times to a total of 178 participants. After the implementation phase another 16 facilitators were trained, and program materials were successfully disseminated. The implementation of AMB-NL was well performed. The targeted aim is not fully reached within the two-year timeframe, but the program is well received by participants, trainers and homecare organizations. Further implementation and maintenance of AMB-NL in primary health care is recommended.

Full Text Available Although developing strategic and operational plans is a difficult and complicated process, their successful implementation is much more difficult. Many organizations fail in the full implementation of their strategies. This is not due to the partial definition of strategies and organization‘s operational plan, but this is likely due to the lack of strong framework for creating alignment between employees and operational process and the organizational goals. To implement strategies effectively and to develop a comprehensive management system and to improve the performance, Robert Kaplan and David Norton introduced a modern management system which is Balanced ScoreCard. Likewise they introduced five main criteria: leadership, translation, alignment, every day process and ongoing process for a strategy oriented organization. This paper is intended to offer a systematic approach for measuring the effectiveness and efficiency of the strategic plan performance. For this study the questionnaire was distributed in a project- orientated service organization and after collection, by the use of statistical. Analysis especially factor analysis the grouping of sub-criteria under the five main criteria was confirmed. The statistical analysis showed that, two criteria of alignment and every day work had the lowest scores in terms of both implementation and effectiveness in the organization‘s senior and executive manager‘s point of view. With deep interview, studying of scorecards and meeting of the strategic committee of the studied organization, the two dimension of alignment and every day work were further examined and after identifying upgradeable areas, some suggestions for improving the effectiveness and efficiency of the studied organization were presented.

Background and objectives African Americans are disproportionately affected by ESRD, but few receive a living donor kidney transplant. Surveys assessing attitudes toward donation have shown that African Americans are less likely to express a willingness to donate their own organs. Studies aimed at understanding factors that may facilitate the willingness of African Americans to become organ donors are needed. Design, setting, participants, & measurements A novel formative research method was used (the nominal group technique) to identify and prioritize strategies for facilitating increases in organ donation among church-attending African Americans. Four nominal group technique panel interviews were convened (three community and one clergy). Each community panel represented a distinct local church; the clergy panel represented five distinct faith-based denominations. Before nominal group technique interviews, participants completed a questionnaire that assessed willingness to become a donor; 28 African-American adults (≥19 years old) participated in the study. Results In total, 66.7% of participants identified knowledge- or education-related strategies as most important strategies in facilitating willingness to become an organ donor, a view that was even more pronounced among clergy. Three of four nominal group technique panels rated a knowledge-based strategy as the most important and included strategies, such as information on donor involvement and donation-related risks; 29.6% of participants indicated that they disagreed with deceased donation, and 37% of participants disagreed with living donation. Community participants’ reservations about becoming an organ donor were similar for living (38.1%) and deceased (33.4%) donation; in contrast, clergy participants were more likely to express reservations about living donation (33.3% versus 16.7%). Conclusions These data indicate a greater opposition to living donation compared with donation after one’s death

Full Text Available This paper presents a study of strategy formation process with the following starting question: "How the strategy is shaped in an innovative company and how the factors manifesting in the process?". The research builds on a case study of a company considered innovative leader in its industry and a pioneer in providing various services in the area of mobile phone in Brazil. Data collection was through interviews semi-structured with directors and managers involved in strategy formation, supplemented by documents and direct observation. Data analysis is based on the techniques of discourse analysis, from the persuasion strategies suggested by Linhares and Faria (1993. The company's strategy studied can be defined as an entrepreneurial vision, focused on growth supported by a process of diversification of product lines from a new direction composed of three elements: (i componentization; (ii segmentation by products chain and; (iii external to finance leverage in order to resumption of innovative projects. It was concluded that the company's strategy focused on these three factors, supported by a deliberate vision of the future, conditions its historical trajectory type standard cultural, its core values, which acts as a motivator and guide for members of the organization decisions and actions.

To ensure an appropriate management of potential health risks and uncertainties from the release of trace organic chemicals (TOrCs) into the aqueous environment, many countries have evaluated and implemented strategies to manage TOrCs. The aim of this study was to evaluate existing management strategies for TOrCs in different countries to derive and compare underlying core principles and paradigms and to develop suggestions for more holistic management strategies to protect the environment and drinking water supplies from the discharge of undesired TOrCs. The strategies in different industrial countries were summarized and subsequently compared with regards to three particular questions: 1) Do the approaches different countries have implemented manage all or only specific portions of the universe of chemicals; 2) What implementation and compliance strategies are used to manage aquatic and human health risk and what are their pros and cons; and 3) How are site-specific watershed differences being addressed? While management strategies of the different countries target similar TOrCs, the programs differ in several important aspects, including underlying principles, the balance between aquatic or human health protection, implementation methods, and financing mechanisms used to fund regulatory programs.

Full Text Available Organic agriculture in Uganda is developing at a fast pace and despite this trend Uganda is still unable to produce enough fresh and dry organic fruits mainly pineapple to meet the exporters demand. This current research investigated the strategies of farmers at production level by assessing the pros and cons of fruit growing, organic agriculture and fruit drying in order to understand the underlying causal factor for the low production of organic dry fruits in a major fruit producing district of Uganda.The study was carried out in two separate and distinctive areas; one which only produces and export fresh organic pineapple and the other which exports dried fruits (mainly pineapple and papaya. About 10% of the farmers in the two study areas were surveyed using questionnaires which were further followed by semi-structured interviews and participatory rural appraisals activities with various types of farmers in order to understand the different decisions and strategies of farmers.82% and 74% of farmers in the two study areas grew fruits as it gave better economic returns and for 77% and 90% respectively in the two study areas, the reasons for growing fruit was the ease of selling compared to other crops. All the farmers were relying on coffee husk for growing organic pineapples. However, 50% of the farmers want to grow pineapples (either organic or conventional but couldn't afford to buy coffee husk. Fruit drying was mainly a strategy to utilize cheap fruits during harvesting seasons for value addition. 71% and 42% of farmers in the two study areas wanted to dry fruits but it was beyond their economic capacity to buy the driers.Decision of the farmers whether to grow fruits or cereals, organic or conventional agriculture and selling the fruits as fresh or dry were dependent mainly on the economic, knowledge and resource availability of each type of practices. It is concluded that the main barrier for an increase in the production of organic dried

Materials from Tutorials in Introductory Physics, originally designed and implemented by the Physics Education Group at the University of Washington, were used in modified form as interactive lectures under conditions significantly different from those suggested by the curriculum developers. Student learning was assessed using tasks drawn from the physics education research literature. Use of tutorials in the interactive lecture format yielded gains in student understanding comparable to those obtained through the canonical tutorial implementation at the University of Washington, suggesting that student engagement with the intellectual steps laid out in the tutorials, rather than the specific strategies used in facilitating such engagement, plays the central role in promoting student learning. We describe the implementation details and assessment of student learning for two different tutorials: one focused on mechanical waves, used at North Dakota State University, and one on Galilean relativity, used at Western Washington University. Also discussed are factors that may limit the generalizability of the results.

This paper presents a political economic framework for viewing the social organization of the delivery of health care servies and predicting a qualitatively different institutional configuration involving the health maintenance organization. The principal forces impacting American capitalism today are leading to a fundamental restructuring for increased social efficiency of the entire social welfare sector, including the health services industry. The method to achieve this restructuring involves health policy directed at raising the contribution to the social surplus from the delivery of health care services and eventual corporate domination. The health maintenance organization conceptualization is examined with suggestions as to how the HMO strategy promoted by the state leads to this corporate takeover. The mechanism and extent of the present corporate involvement are examined and implications of health services as a social control mechanism are presented.

Metal-organic polyhedra-discrete molecular architectures constructed through the coordination of metal ions and organic linkers-have recently attracted considerable attention due to their intriguing structures, their potential for a variety of applications and their relevance to biological self-assembly. Several synthetic routes have been investigated to prepare these complexes. However, to date, these preparative methods have typically been based on the direct assembly of metal ions and organic linkers. Although these routes are convenient, it remains difficult to find suitable reaction conditions or to control the outcome of the assembly process. Here, we demonstrate a synthetic strategy based on the substitution of bridging ligands in soluble metal-organic polyhedra. The introduction of linkers with different properties from those of the initial metal-organic polyhedra can thus lead to new metal-organic polyhedra with distinct properties (including size and shape). Furthermore, partial substitution can also occur and form mixed-ligand species that may be difficult to access by means of other approaches.

Developing tissues contain motile populations of cells that can self-organize into spatially ordered tissues based on differences in their interfacial surface energies. However, it is unclear how self-organization by this mechanism remains robust when interfacial energies become heterogeneous in either time or space. The ducts and acini of the human mammary gland are prototypical heterogeneous and dynamic tissues comprising two concentrically arranged cell types. To investigate the consequences of cellular heterogeneity and plasticity on cell positioning in the mammary gland, we reconstituted its self-organization from aggregates of primary cells in vitro. We find that self-organization is dominated by the interfacial energy of the tissue-ECM boundary, rather than by differential homo- and heterotypic energies of cell-cell interaction. Surprisingly, interactions with the tissue-ECM boundary are binary, in that only one cell type interacts appreciably with the boundary. Using mathematical modeling and cell-type-specific knockdown of key regulators of cell-cell cohesion, we show that this strategy of self-organization is robust to severe perturbations affecting cell-cell contact formation. We also find that this mechanism of self-organization is conserved in the human prostate. Therefore, a binary interfacial interaction with the tissue boundary provides a flexible and generalizable strategy for forming and maintaining the structure of two-component tissues that exhibit abundant heterogeneity and plasticity. Our model also predicts that mutations affecting binary cell-ECM interactions are catastrophic and could contribute to loss of tissue architecture in diseases such as breast cancer.

To review the components of the Congressional mandate for risk evaluation and mitigation strategies (REMS) managed by the Food and Drug Administration and assess their impact on health care providers practicing within the organ transplant arena. A non-date-limited search of MEDLINE and EMBASE (January 2007-June 2012) was conducted by using the following search terms: risk evaluation and mitigation strategies, REMS, and organ transplant, including a query of the individual organs. Information from the Federal Register and the Food and Drug Administration was also evaluated. REMS are strategies implemented to manage known or potential risks associated with medications and to ensure ongoing pharmacovigilance throughout the life of a pharmaceutical product. Elements of REMS programs may consist of 3 levels: a medication guide, communication plan, and elements to assure safe use. A medication guide is used to help prevent serious adverse events, aid in patients' decision making, and enhance medication adherence. Communication plans help educate health care providers and encourage adherence with REMS. The elements to assure safe use is a restrictive process implemented when it is deemed necessary to ensure safe access for patients to products with known serious risks. In transplant medicine, REMS currently exist for belatacept (medication guide and communication plan) and the mycophenolic acid derivatives (medication guide and elements to assure safe use). REMS are another step in the evolution of the development and marketing of pharmaceutical agents. Use of REMS in solid-organ transplant is becoming common. Transplant clinicians must provide required patient education and become involved with other aspects of REMS implementation to reduce the serious risks of pharmaceuticals and to improve patients' outcomes.

This study is a formative evaluation of problem-based learning as an effective course delivery strategy in a second year introductory Medical Laboratory Technician discipline-specific hematology course. This strategy can serve two purposes in this type of course: discipline specific content knowledge and process skills learning. A needs study identified that students required additional workplace skills as they entered the clinical internship. Students tested well on the national registry examinations, discipline-specific content knowledge, but group process skills needed improvement in the areas of collaboration, communication, and critical reasoning. Problem-based learning was identified as an change intervention to help provide these skills. A search of the literature revealed that the Baker College cultural and physical environment would support this intervention. Twelve cases were written, situated in a clinical laboratory environment, addressing learning issues identified in a modified Delphi survey of laboratory personnel e.g. fiscal responsibility, turn-around time, invasiveness of laboratory techniques, and holistic view of healthcare environment. A hematology class of 13 students received the intervention. The cases were structured to proceed from instructor-centered (guided) learning issues to learner-centered learning issues. Observations of the in-group collaboration processes were documented, as well as oral presentations and critical reasoning, with students given periodic feedback on these skills. Student surveys provided data about satisfaction, attitude to PBL process, and self-efficacy. Multiple choice discipline-specific content examinations were given and compared with classes from the previous four years. The study found that students receiving the PBL treatment scored as well as or better than students from previous years on traditional multiple choice exams. Recall questions showed positive significance and application/analysis questions
Full Text Available This study investigated the integrating possibilities within each creative arts subject. The objective was to optimize the limited teaching time, generally allocated to each art subject in schools, by developing a pedagogical strategy for its successful implementation. While the study was limited to South African schools, the results have global relevance and significance in the ongoing global trendsetting and discourse on arts education. In South Africa the previous National Curriculum Statement (NCS, 2002 integrated music, dance, drama and visual arts where possible, while the new Curriculum and Assessment Policy Statement (CAPS, 2011 offers two elective art subjects in the senior phase (Grades 7-9, each taught separately an hour per week during school hours and one hour per week after school, thereby attempting to extend the teaching time. This qualitative enquiry used documentary analyses, teacher interviews, and student group discussions for the collection of data. Pre-determined and emergent codes based on grounded theory showed that it is possible to integrate theory with practice within one art subject by teaching theoretical work in the context of practical work, thus optimizing the limited time allocated to arts and culture education in school timetables.
Over the last two decades, online education has become a popular concept in universities as well as K-12 education. This generation of students has grown up using technology and has shown interest in incorporating technology into their learning. The idea of using technology in the classroom to enhance student learning and create higher achievement has become necessary for administrators, teachers, and policymakers. Although online education is a popular topic, there has been minimal research on the effectiveness of online and blended learning strategies compared to the student learning in a traditional K-12 classroom setting. The purpose of this study was to investigate differences in standardized test scores from the Biology End of Course exam when at-risk students completed the course using three different educational models: online format, blended learning, and traditional face-to-face learning. Data was collected from over 1,000 students over a five year time period. Correlation analyzed data from standardized tests scores of eighth grade students was used to define students as "at-risk" for failing high school courses. The results indicated a high correlation between eighth grade standardized test scores and Biology End of Course exam scores. These students were deemed "at-risk" for failing high school courses. Standardized test scores were measured for the at-risk students when those students completed Biology in the different models of learning. Results indicated significant differences existed among the learning models. Students had the highest test scores when completing Biology in the traditional face-to-face model. Further evaluation of subgroup populations indicated statistical differences in learning models for African-American populations, female students, and for male students.

Although polar organic contaminants (POCs) such as pharmaceuticals are considered as some of today's most emerging contaminants few of them are regulated or included in on-going monitoring programs. However, the growing concern among the public and researchers together with the new legislature within the European Union, the registration, evaluation and authorisation of chemicals (REACH) system will increase the future need of simple, low cost strategies for monitoring and risk assessment of POCs in aquatic environments. In this article, we overview the advantages and shortcomings of traditional and novel sampling techniques available for monitoring the emerging POCs in water. The benefits and drawbacks of using active and biological sampling were discussed and the principles of organic passive samplers (PS) presented. A detailed overview of type of polar organic PS available, and their classes of target compounds and field of applications were given, and the considerations involved in using them such as environmental effects and quality control were discussed. The usefulness of biological sampling of POCs in water was found to be limited. Polar organic PS was considered to be the only available, but nevertheless, an efficient alternative to active water sampling due to its simplicity, low cost, no need of power supply or maintenance, and the ability of collecting time-integrative samples with one sample collection. However, the polar organic PS need to be further developed before they can be used as standard in water quality monitoring programs.

A long-standing scientific discourse on the use of health research evidence to inform policy has come to produce multiple implementation theories, frameworks, models, and strategies. It is from this extensive body of research that the authors extract and present essential components of an implementation process in the health domain, gaining valuable guidance on how to successfully meet the challenges of implementation. Furthermore, this article describes how implementation content can be analyzed and reorganized, with a special focus on implementation at different policy, systems and services, and individual levels using existing frameworks and tools. In doing so, the authors aim to contribute to the establishment and testing of an implementation framework for reports such as the World Health Organization World Report on Disability, the World Health Organization International Perspectives on Spinal Cord Injury, and other health policy reports or technical health guidelines.

The distribution of management structures in health care has been shifting from independent ownership to interorganizational relationships with other firms. A shortage of resources has been cited as one cause for such collaboration among health care entities. The resource- based view of the firm suggests that organizations differentiate between strategic alliances and acquisition strategies based on a firm's internal resources and the types of resources a potential partner organization possesses. This paper provides a review of the literature using the resource-based theory of the firm to understand what conditions foster different types of health care partnerships. A model of partnership alliances using the resource-based view is presented, strategic linkages are presented, managerial implications are outlined, and directions for future research are given.

Full Text Available The modern society, in order to reach its current stage of development, has been through stages whose patterns have been stocked as important archives, which they constituted and built up a chain of values that allow us to call/ name the modern society a society of knowledge. The knowledge has become, by far, the most important asset and resource to which we report ourselves to into the organized and non-organized fields of our nowadays society, and the nature, evolution, dynamics of these organized domains of business entities have become a subject of fundamental importance to maximize their competitive advantage. In that matter, the scientific, theoretical, practical knowledge or the one resulted from experience, is the key determiner to acquire modern corporate success, at least in the more global context of markets and business processes. This paperwork comes to complete the idea, according to which, the competitive advantage of modern business entities/ corporations can’t be reached unless the general management strategy would include: processes, principles, techniques to make/ to create this knowledge productive, meaning to include the knowledge management strategy into the general one of the specific corporation. Another important aspect we want to emphasize is the importance of reporting ourselves to knowledge as a key factor for the development of the academic environment/ domain, as well as for the one of business organizations. In the present, workers are using more and more their minds rather than their hands, and the idea of knowledge worker in the business area has its roots, as we believe, in the institutional education. The high level of absorbing individuals who own intangible active stocks/ knowledgeis bigger and bigger, and this thing wouldn’t be possible without looking towards the academic domain as the main determiner in developing the human factor, and also being the supplier that fuels the quality of employment

Organic semiconductors (OSCs) have been extensively studied as sensing channel materials in field-effect transistors due to their unique charge transport properties. Stimulation caused by its environmental conditions can readily change the charge-carrier density and mobility of OSCs. Organic field-effect transistors (OFETs) can act as both signal transducers and signal amplifiers, which greatly simplifies the device structure. Over the past decades, various sensors based on OFETs have been developed, including physical sensors, chemical sensors, biosensors, and integrated sensor arrays with advanced functionalities. However, the performance of OFET-based sensors still needs to be improved to meet the requirements from various practical applications, such as high sensitivity, high selectivity, and rapid response speed. Tailoring molecular structures and micro/nanofilm structures of OSCs is a vital strategy for achieving better sensing performance. Modification of the dielectric layer and the semiconductor/dielectric interface is another approach for improving the sensor performance. Moreover, advanced sensory functionalities have been achieved by developing integrated device arrays. Here, a brief review of strategies used for improving the performance of OFET sensors is presented, which is expected to inspire and provide guidance for the design of future OFET sensors for various specific and practical applications. © 2018 WILEY-VCH Verlag GmbH & Co.

Full Text Available The purpose of this proposal is to explore a new concept of 'Metadistrict' to be applied in a region of Southern Italy – Apulia ‐ in order to analyze the impact that the activation of a special network between different sector chains and several integrated projects may have for revitalizing the local economy; an important role is assigned to the network of relationships and so to the social capital. The Metadistrict model stems from the Local Action Groups and the Integrated Projects of Food Chain frameworks. It may represent a crucial driver of the rural economy through the realization of sector circuits connected to the concept of multi‐functionality in agriculture, that is Network of the Territorial Multi‐functionality. It was formalized by making use of a set of theories and of a Matrix Organization Model. The adoption of the Metadistrict perspective as the territorial strategy may play a key role to revitalize the primary sector, through the increase of economic and productive opportunities due to the implementation of a common and shared strategy and organization.

Limited by the various inherent energy losses from multiple channels, organic solar cells show inferior device performance compared to traditional inorganic photovoltaic techniques, such as silicon and CuInGaSe. To alleviate these fundamental limitations, an integrated multiple strategy is implemented including molecular design, interfacial engineering, optical manipulation, and tandem device construction into one cell. Considering the close correlation among these loss channels, a sophisticated quantification of energy-loss reduction is tracked along with each strategy in a perspective to reach rational overall optimum. A novel nonfullerene acceptor, 6TBA, is synthesized to resolve the thermalization and V OC loss, and another small bandgap nonfullerene acceptor, 4TIC, is used in the back sub-cell to alleviate transmission loss. Tandem architecture design significantly reduces the light absorption loss, and compensates carrier dynamics and thermalization loss. Interfacial engineering further reduces energy loss from carrier dynamics in the tandem architecture. As a result of this concerted effort, a very high power conversion efficiency (13.20%) is obtained. A detailed quantitative analysis on the energy losses confirms that the improved device performance stems from these multiple strategies. The results provide a rational way to explore the ultimate device performance through molecular design and device engineering. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The aim of this study was to evaluate our results of treatment for acute type IIIb aortic dissection associated with malperfusion of abdominal organs, and to consider the therapeutic strategies. Between December 1997 and August 2005, 123 patients with acute type IIIb aortic dissection were treated at our hospital. Of those, 11 patients (8.9%) required emergency treatment for malperfusion of abdominal organ. In our hospital, the indication of emergency treatment for acute type IIIb aortic dissection was any symptom of acute abdomen plus insufficiency of visceral arterial circulation on computed tomography or angiography. All of the 11 patients (100%) had cul-de-sac of a false lumen, 8 (72.7%) had at least one symptom of acute abdomen, and 3 (27.3%) had metabolic acidosis before surgical treatment. In 7 patients of the ''true lumen stenosis type,'' 5 patients who were treated with open stent grafting are alive. The other two patients, who were treated with transluminally placed endovascular stent grafting (TPEG) or with superior mesenteric artery (SMA) bypass, died. Of the 2 ''visceral arterial dissection type'' patient, one was treated with transluminal stenting of the celiac artery and the other was treated with resection of the intestine and ileocolic artery bypass, and both are alive. Two ''mixed type'' patients who were treated with open stent grafting died. The mortality rate of this series was 36.4%. In conclusion, to improve the prognosis of acute type IIIb aortic dissection associated with malperfusion of abdominal organ, it is important that we obtain early diagnosis of organ ischemia caused by cul-de-sac of a false lumen and choose the correct treatment based on understanding of the mechanism of organ ischemia.

Medical physicists face numerous challenges that create stress in the professional workplace. The modern work environment contains multiple communications channels, such as email, smart phones, text and instant messaging, voice mail, pagers, and more. These media make it difficult to organize incoming information, set priorities, and move important work forward in the face of rapid change and the requirement to fulfill multiple responsibilities. Medical physicists in particular are likely to feel acute stress due to off-peak work hour requirements, varied responsibilities including clinical duties, research, teaching, and regulatory matters, and the complexity of supervising other staff members. Many medical physicists also work in multiple physical locations, adding complexity to the task of organizing information and resources. Another common difficulty is that medical physicists' responsibilities typically include some duties that render them subject to frequent and urgent interruption, such as emergency response coverage for radiation safety. The real challenges in the current medical physics work environment differ from those encountered while taking courses and conducting research, as well as from earlier periods when medical physicists faced fewer varied responsibilities, slower-paced change, or both. Today's practicing physicist can benefit greatly from developing a formal framework and skill set to manage their personal workflow. This greatly increases the individual's effectiveness and reduces feelings of stress, while improving the effectiveness of teams or groups in which they participate. In this session, participants will learn about a number of techniques and strategies to manage their own personal workflow. Examples familiar to the medical physicist will be provided to illustrate methods to capture, organize, and act on important information, to delegate effectively, and to handle inevitable interruptions. 1.

The objective of the study was to understand and characterize the involvement of Portuguese NGOs, or of those based in Portugal, in the field of the environment, identifying and evaluating the relationships they have established with external partners, namely with regard to the following: privileged countries; types of partners; intervention areas; methodologies and tools. The study was based on the concepts of development cooperation, including players and tools, partnership in international relations, and social and environmental sustainability, taking also into account the Millennium Development Goals, in particular as regards the Seventh Target: Guaranteeing Environmental Sustainability. Given the broad scope of the study, a short questionnaire was built following the principle of guaranteed anonymity and made available online. After making a list of NGOs (ENGOs and DNGOs, the questionnaire was sent to many of these organizations, requesting them to respond to the questionnaire (N=43. From the data analysis and by confronting it with the concepts previously explored, it emerged that the majority undertake joint activity in Portugal and in partner countries, mostly with other similar organizations after the establishment of partnerships. The activity focuses on social and environmental projects of local relevance, with mixed funding that is mostly international in nature, and has clear objectives for promoting development.

Research was conducted among 200 managers at the top, middle and operational levels of management (200 companies operating in Poland implementing innovations - innovative companies. Conditions leading to innovations are described as the combination of processes, which result from the internal and external dynamics of a given entity. The analysis assumed that the assessment of company innovativeness would be based on an assessment of whether the company is a leader in the industry in terms of new products (the higher the rating, the more innovative the company is considered to be. The relationship between the dimensions of the company's functioning and the degree of its innovativeness was rated on the basis of two measures: the Spearman's rank correlation coefficient and the chi-square coefficient. It was assumed that the most innovative companies have structures similar to organic ones, with a weak influence of the elements of mechanistic structures. This assumption was proven in relation to features of organizations considered important for innovativeness.

Implementation of the Affordable Care Act (ACA) creates both environmental uncertainties and opportunities for substance use disorder (SUD) treatment providers. One managerial response to uncertainties and emergent opportunities is strategic diversification of various dimensions of organizational activity. This paper explored organizational outcomes related to diversification of funding sources, services offered, and referral sources in a national sample of 590 SUD treatment organizations. Funding diversification was related to higher average levels of census, organization size, and recent expansion of operations. Service diversification was related to higher average levels of use of medication-assisted treatment (MAT), organization size, and expansion. Referral source diversification was related only to greater average use of MAT. Overall, strategic diversification in the three areas explored was related to positive organizational outcomes. Considering alternative strategies of diversification may help position SUD treatment centers to deliver more innovative treatments such as MAT as well as enhance capacity to satisfy current unmet treatment needs of individuals with behavioral health coverage provided under the ACA.

Full Text Available What most sensed about Technical High School (known as SMK students is their lack of analytical capability. As their nature of academic orientation is aimed at job fullfillment, the students are enhanced to follow Standard Operational Procedure (SOP without questioning why such SOP should be followed. As for automotive students, they simply following the steps of doing things related to any activities of repairing car and other mechanical work required just because the job will be done well when the procedure completed. This kind of mentality “following order or SOP” fits to those who only want to be workers not the men who take higher responsibilities. The progress of automotive technology demand on understanding the concept of how some system used in a car. Failure to comprehend to concept will jeopardize the performance of a car. At the same time, the progress of automotive technology is also propelled by the progress of information technology which provides more open resources that can be used to promote the quality of instuctional process. Realizing that having analysis compentence is terribly important to run higher responsibilites and continuing education to a university, automotive students need to learn how to analyze. To promote this, teacher can use some automotive movies or animations and then chop them into many fragments related to instructional objectives. The way how the teachers arrange and present the fragments can be combined into power point and ended up with an interactive test with different model of methods, strategies, or techniques. Movies, movie cutter application, interactive test Creator , paint into fragments can be obtained freely from the internet. The using of movie fragments integrated into power point, arrange the fragment into various strategies, ended up with interactive test will likely focus the students into more realistic understanding toward the concept taught in the classroom.

Organic contaminants in shale gas flowback and produced water (FPW) are traditionally expressed as total organic carbon (TOC) or chemical oxygen demand (COD), though these parameters do not provide information on the toxicity and environmental fate of individual components. This review addresses identification of individual organic contaminants in FPW, and stresses the gaps in the knowledge on FPW composition that exist so far. Furthermore, the risk quotient approach was applied to predict the toxicity of the quantified organic compounds for fresh water organisms in recipient surface waters. This resulted in an identification of a number of FPW related organic compounds that are potentially harmful namely those compounds originating from shale formations (e.g., polycyclic aromatic hydrocarbons, phthalates), fracturing fluids (e.g., quaternary ammonium biocides, 2-butoxyethanol) and downhole transformations of organic compounds (e.g., carbon disulfide, halogenated organic compounds). Removal of these compounds by FPW treatment processes is reviewed and potential and efficient abatement strategies are defined. PMID:28376616

This is a case study in the municipality of Rio de Janeiro about management in the Family Health Strategy based on the Social Organizations model. The aims were to characterize and analyze aspects of the governance system adopted by the Rio de Janeiro Municipal Health Department and identify limits and possibilities of this model as a management option in Brazil's Unified Health System. A qualitative study was performed based on a literature review, document analysisand interviews with key informants. This management model facilitated the expansion of access to primary healthcare through the Family Health Strategy in Rio - where the population covered increased from 7.2% of the population in 2008 to 45.5% in 2015. The results showthat some practices in the contractual logic need to be improved, including negotiation and accountability with autonomywith the service suppliers. Evaluation and control has focus on processes, not results, and there has not been an increase in transparency and social control. The system of performance incentives has been reported as inducing improvements in the work process of the health teams. It is concluded that the regulatory capacity of the municipal management would need to be improved. On the other hand, there is an important and significant process of learning in progress.

Clinical transplant tolerance has been most successfully achieved combining hematopoietic chimerism with kidney transplantation. This review outlines this strategy in animal models and human transplantation, and possible clinical challenges. Kidney transplant tolerance has been achieved through chimerism in several centers beginning with Massachusetts General Hospital's success with mixed chimerism in human leukocyte antigen (HLA)-mismatched patients and the Stanford group with HLA-matched patients, and the more recent success of the Northwestern protocol achieving full chimerism. This has challenged the original view that stable mixed chimerism is necessary for organ graft tolerance. However, among the HLA-mismatched kidney transplant-tolerant patients, loss of mixed chimerism does not lead to renal-graft rejection, and the development of host Foxp3+ regulatory T cells has been observed. Recent animal models suggest that graft tolerance through bone marrow chimerism occurs through both clonal deletion and regulatory immune cells. Further, Tregs have been shown to improve chimerism in animal models. Animal studies continue to suggest ways to improve our current clinical strategies. Advances in chimerism protocols suggest that tolerance may be clinically achievable with relative safety for HLA-mismatched kidney transplants.

Full Text Available Abstract Background The rates of antimicrobial-resistant organisms (ARO continue to increase for both hospitalized and community patients. Few resources have been allocated to reduce the spread of resistance on global, national and local levels, in part because the broader economic impact of antimicrobial resistance (i.e. the externality is not fully considered when determining how much to invest to prevent AROs, including strategies to contain antimicrobial resistance, such as antimicrobial stewardship programs. To determine how best to measure and incorporate the impact of externalities associated with the antimicrobial resistance when making resource allocation decisions aimed to reduce antimicrobial resistance within healthcare facilities, we reviewed the literature to identify publications which 1 described the externalities of antimicrobial resistance, 2 described approaches to quantifying the externalities associated with antimicrobial resistance or 3 described macro-level policy options to consider the impact of externalities. Medline was reviewed to identify published studies up to September 2016. Main body An externality is a cost or a benefit associated with one person’s activity that impacts others who did not choose to incur that cost or benefit. We did not identify a well-accepted method of accurately quantifying the externality associated with antimicrobial resistance. We did identify three main methods that have gained popularity to try to take into account the externalities of antimicrobial resistance, including regulation, charges or taxes on the use of antimicrobials, and the right to trade permits or licenses for antimicrobial use. To our knowledge, regulating use of antimicrobials is the only strategy currently being used by health care systems to reduce antimicrobial use, and thereby reduce AROs. To justify expenditures on programs that reduce AROs (i.e. to formally incorporate the impact of the negative externality of

Large-scale fabrication of organic solar cells requires an active layer with high thickness tolerability and the use of environment-friendly solvents. Thick films with high-performance can be achieved via a ternary strategy studied herein. The ternary system consists of one polymer donor, one small molecule donor, and one fullerene acceptor. The small molecule enhances the crystallinity and face-on orientation of the active layer, leading to improved thickness tolerability compared with that of a polymer-fullerene binary system. An active layer with 270 nm thickness exhibits an average power conversion efficiency (PCE) of 10.78%, while the PCE is less than 8% with such thick film for binary system. Furthermore, large-area devices are successfully fabricated using polyethylene terephthalate (PET)/Silver gride or indium tin oxide (ITO)-based transparent flexible substrates. The product shows a high PCE of 8.28% with an area of 1.25 cm 2 for a single cell and 5.18% for a 20 cm 2 module. This study demonstrates that ternary organic solar cells exhibit great potential for large-scale fabrication and future applications. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The acceptability of financial incentives for organ donation is contentious. This study sought to determine (1) the acceptability of expense reimbursement or financial incentives by the general public, health professionals involved with organ donation and transplantation, and those with or affected by kidney disease and (2) for the public, whether financial incentives would alter their willingness to consider donation. Web-based survey administered to members of the Canadian public, health professionals, and people with or affected by kidney disease asking questions regarding acceptability of strategies to increase living and deceased kidney donation and willingness to donate a kidney under various financial incentives. Responses were collected from 2004 members of the Canadian public October 11-18, 2011; responses from health professionals (n=339) and people with or affected by kidney disease (n=268) were collected during a 4-week period commencing October 11, 2011. Acceptability of one or more financial incentives to increase deceased and living donation was noted in >70% and 40% of all groups, respectively. Support for monetary payment for living donors was 45%, 14%, and 27% for the public, health professionals, and people with or affected by kidney disease, respectively. Overall, reimbursement of funeral expenses for deceased donors and a tax break for living donors were the most acceptable. The general public views regulated financial incentives for living and deceased donation to be acceptable. Future research needs to examine the impact of financial incentives on rates of deceased and living donors.

In view of the high biotoxicity and trace concentration of mercury (Hg) in environmental water, developing simple, ultra-sensitive and highly selective method capable of simultaneous determination of various Hg species has attracted wide attention. Here, we present a novel catalysis-reduction strategy for sensing inorganic and organic mercury in aqueous solution through the cooperative effect of AuNP-catalyzed properties and the formation of gold amalgam. For the first time, a new AuNP-catalyzed-organic reaction has been discovered and directly used for sensing Hg 2+ , Hg 2 2+ and CH 3 Hg + according to the change of the amount of the catalytic product induced by the deposition of Hg atoms on the surface of AuNPs. The detection limit of Hg species is 5.0pM (1 ppt), which is 3 orders of magnitude lower than the U.S. Environmental Protection Agency (EPA) limit value of Hg for drinking water (2 ppb). The high selectivity can be exceptionally achieved by the specific formation of gold amalgam. Moreover, the application for detecting tap water samples further demonstrates that this AuNP-based assay can be an excellent method used for sensing mercury at very low content in the environment.

A significant and ongoing challenge in materials chemistry and furthermore solid state chemistry is to design materials with the desired properties and characteristics. The field of Metal-Organic Frameworks (MOFs) offers several strategies to address this challenge and has proven fruitful at allowing some degree of control over the resultant materials synthesized. Several methodologies for synthesis of MOFs have been developed which rely on use of predetermined building blocks. The work presented herein is focused on the utilization of two of these design principles, namely the use of molecular building blocks (MBBs) and supermolecular building blocks (SBBs) to target MOF materials having desired connectivities (topologies). These design strategies also permit the introduction of specific chemical moieties, allowing for modification of the MOFs properties. This research is predominantly focused on two platforms (rht-MOFs and ftw-MOFs) which topologically speaking are edge transitive binodal nets; ftw being a (4,12)-connected net and rht being a (3,24)-connected net. These highly connected nets (at least one node having connectivity greater than eight) have been purposefully targeted to increase the predictability of structural outcome. A general trend in topology is that there is an inverse relationship between the connectivity of the node(s) and the number of topological outcomes. Therefore the key to this research (and to effective use of the SBB and MBB approaches) is identification of conditions which allow for reliable formation of the targeted MBBs and SBBs. In the case of the research presented herein: a 12-connected Group IV or Rare Earth based hexanuclear MBB and a 24-connected transition metal based SBB were successfully targeted and synthesized. These two synthetic platforms will be presented and used as examples of how these design methods have been (and can be further) utilized to modify existing materials or develop new materials for gas storage and

The polymerase chain reaction (PCR) is the current state of the art technique for DNA-based detection of Genetically Modified Organisms (GMOs). A typical control strategy starts by analyzing a sample for the presence of target sequences (GM-elements) known to be present in many GMOs. Positive findings from this "screening" are then confirmed with GM (event) specific test methods. A reliable knowledge of which GMOs are detected by combinations of GM-detection methods is thus crucial to minimize the verification efforts. In this article, we describe a novel platform that links the information of two unique databases built and maintained by the European Union Reference Laboratory for Genetically Modified Food and Feed (EU-RL GMFF) at the Joint Research Centre (JRC) of the European Commission, one containing the sequence information of known GM-events and the other validated PCR-based detection and identification methods. The new platform compiles in silico determinations of the detection of a wide range of GMOs by the available detection methods using existing scripts that simulate PCR amplification and, when present, probe binding. The correctness of the information has been verified by comparing the in silico conclusions to experimental results for a subset of forty-nine GM events and six methods. The JRC GMO-Matrix is unique for its reliance on DNA sequence data and its flexibility in integrating novel GMOs and new detection methods. Users can mine the database using a set of web interfaces that thus provide a valuable support to GMO control laboratories in planning and evaluating their GMO screening strategies. The platform is accessible at http://gmo-crl.jrc.ec.europa.eu/jrcgmomatrix/ .

Full Text Available The reason why the Trayvon Martin murder trial and similar court cases create a philosophical rift in our nation is due in part to flaws in the delivery of multicultural education. Traditional multicultural instruction does not prepare citizens for the subtleties and complexities of race relations. This study investigates critical strategies and practices that address multicultural missing gaps. I also seek to fill a void in the literature created by a lack of student input regarding teaching strategies that encourage lifelong learning. Students (N = 337 enrolled at a Midwestern university were asked to rate the efficacy of selected instructional strategies. Utilizing a 9-point Likert-type scale, students gave themselves a personal growth rating of 7.15 (SD = 1.47. Variables important to predicting that growth (R2 = .56, p < .0005 were a six-factor variable known as a non-color-blind instructional approach (t = 10.509, p ≤ .0005, allowing students an opportunity to form their own opinions apart from the instructor (t = 4.797, p ≤ .0005, and a state law that mandated multicultural training (t = 3.234, p = .001. Results demonstrated that utilizing a 35% traditional and 65% critical pedagogy mixture when teaching multicultural education helped promote win/win scenarios for education candidates hoping to become difference makers.
Full Text Available We can find the first anticipation of the World Wide Web hypertextual structure in Bush paper of 1945, where he described a “selection” and storage machine called the Memex, capable of keeping the useful information of a user and connecting it to other relevant material present in the machine or added by other users. We will argue that Vannevar Bush, who conceived this type of machine, did it because its involvement with analogical devices. During the 1930s, in fact, he invented and built the Differential Analyzer, a powerful analogue machine, used to calculate various relevant mathematical functions. The model of the Memex is not the digital one, because it relies on another form of data representation that emulates more the procedures of memory than the attitude of the logic used by the intellect. Memory seems to select and arrange information according to association strategies, i.e., using analogies and connections that are very often arbitrary, sometimes even chaotic and completely subjective. The organization of information and the knowledge creation process suggested by logic and symbolic formal representation of data is deeply different from the former one, though the logic approach is at the core of the birth of computer science (i.e., the Turing Machine and the Von Neumann Machine. We will discuss the issues raised by these two “visions” of information management and the influences of the philosophical tradition of the theory of knowledge on the hypertextual organization of content. We will also analyze all the consequences of these different attitudes with respect to information retrieval techniques in a hypertextual environment, as the web. Our position is that it necessary to take into accounts the nature and the dynamic social topology of the network when we choose information retrieval methods for the network; otherwise, we risk creating a misleading service for the end user of web search tools (i.e., search engines.
Full Text Available The gradual elimination of chromium from wood preservative formulations results in higher Cu leaching and increased susceptibility to wood decay fungi. Finding a sustainable strategy in wood protection has become of great interest among researchers. The objective of these in vitro studies was to demonstrate the effect of T-720-enriched organic charcoal (biochar against five wood decay basidiomycetes isolated from strongly damaged poles. For this purpose, the antagonistic potential of Trichoderma harzianum (strain T-720 was confirmed among other four Trichoderma spp. against five brown-rot basidiomycetes in dual culture tests. T-720 was genetically transformed and tagged with the green fluorescent protein (GFP in order to study its antagonistic mechanism against wood decay basidiomycetes. It was also demonstrated that T-720 inhibits the oxalic acid production by basidiomycetes, a well-known mechanism used by brown-rot fungi to detoxify Cu from impregnated wood. Additionally, this study evaluated the effect of biochar, alone or in combination with T-720, on Cu leaching by different preservatives, pH stabilization and prevention of wood decay caused by five basidiomycetes. Addition of biochar resulted in a significant Cu binding released from impregnated wood specimens. T-720-enriched biochar showed a significant reduction of wood decay caused by four basidiomycetes. The addition of T-720-enriched biochar to the soil into which utility poles are placed may improve the efficiency of Cr-free wood preservatives.

HLA matching provides numerous benefits in organ transplantation including better graft function, fewer rejection episodes, longer graft survival, and the possibility of reduced immunosuppression. Mismatches are attended by more frequent rejection episodes that require increased immunosuppression that, in turn, can increase the risk of infection and malignancy. HLA mismatches also incur the risk of sensitization, which can reduce the opportunity and increase waiting time for a subsequent transplant. However, other factors such as donor age, donor type, and immunosuppression protocol, can affect the benefit derived from matching. Furthermore, finding a well-matched donor may not be possible for all patients and usually prolongs waiting time. Strategies to optimize transplantation for patients without a well-matched donor should take into account the immunologic barrier represented by different mismatches: what are the least immunogenic mismatches considering the patient’s HLA phenotype; should repeated mismatches be avoided; is the patient sensitized to HLA and, if so, what are the strengths of the patient’s antibodies? This information can then be used to define the HLA type of an immunologically optimal donor and the probability of such a donor occurring. A probability that is considered to be too low may require expanding the donor population through paired donation or modifying what is acceptable, which may require employing treatment to overcome immunologic barriers such as increased immunosuppression or desensitization. Thus, transplantation must strike a balance between the risk associated with waiting for the optimal donor and the risk associated with a less than optimal donor. PMID:28003816

The students assigned to the experimental group learnt about and acquired literary theory concepts and special characteristics of literary genres within their 'zones of proximal development,' while the lessons taught to the control group were structured to suit an average or imaginary student. The same requirements were set on all students in the control group, regardless of their individual level of familiarity with literary theory notions and concepts and the degree to which they were capable of comprehending and experiencing a literary text. The results of the experiment carried out with such parallel groups show that the achievement of the students included in the experimental group, who were taught according to individualized instruction plans, was better in a way that was statistically significant, in comparison with both their knowledge of the subject matter before the experiment and the control group, whose members attended classes organized in a predominantly traditional, non-individualistic way.

The Health Services, not only the Italian one, is under pressure because of request for improving treatment quality and the financial need for reorganization and cost-saving. It's required a rationalization of intervention, together with a careful choice of the best and cheapest techniques and the demonstration of their efficacy. The anaesthesia service activity, in a period of cost rationalization and funds restriction should be aimed to appropriate outcome measures corrected by both patient's risk factors and surgical-anaesthesiological case-mix. The development of a complete strategy for surgical pain management might run into two phases. The first phase, internal and mono-specialistic, should develop like the creation of an Acute Pain Team. The main processes are: focusing the problem (charge of the care), training, information, teaching methodology (timing, methods, drugs, techniques, etc.) and the audit (before and after changes). The main aims are the evaluation of the level of analgesia and pain relief or patient's satisfaction which are partial endpoints useful to demonstrate the improvement and the efficacy of the new pain management strategies. The second phase, multidisciplinary, is directed toward the creation of a Postoperative Evaluation Team. The main objective is to set up a collaborative clinical group able to identify the criteria for quality, efficacy and safety. The major purpose is the evaluation of major outcome measures: surgical outcome, morbidity, mortality and length of hospitalization. The improvement in the quality of postoperative pain treatment goes through a better organization and a progressive increase of the already available therapy. The achievement of the result and the quality projects depend on the interaction among staff members with different behaviours and settings.

Full Text Available In this research, we use Hofstede method and Noble’s framework in strategy execution to evaluate the effect of organization culture on the successful implementation of strategies in a case study of Payam-e-Noor University of Iran. Data Collection is performed with the standard Hofstede survey, an evaluation tool for organization culture, and researchers’ survey tool to evaluate the effective implementation of strategies. The reliability coefficient was calculated as 0.846 using the Cronbach alpha. The target population includes 600 senior managers of Payam-e-Noor university of Iran at the time of data collection Cochran formula was used to calculate the required sample number of 120 individuals. The results show that according to the Hofstede dimensions, the dominant cultural aspects of high power distance, uncertainty avoidance, collectivism, and femininity were identified. The first two have a direct influence on effectiveness of strategies. While individualism is known to have an invert effect on effectiveness of strategies, no connection was identified between masculinity and effectiveness of strategies, and thus, this theory was not confirmed in this research.

With the discovery of MCM-41 by Mobil researchers in 1992 the journey of the research on mesoporous materials started and in the 21st century this area of scientific investigation have extended into numerous branches, many of which contribute significantly in emerging areas like catalysis, energy, environment and biomedical research. As a consequence thousands of publications came out in large varieties of national and international journals. In this review, we have tried to summarize the published works on various synthetic pathways and formation mechanisms of different mesoporous materials viz. inorganic, organic-inorganic hybrid and purely organic solids via soft templating pathways. Generation of nanoscale porosity in a solid material usually requires participation of organic template (more specifically surfactants and their supramolecular assemblies) called structure-directing agent (SDA) in the bottom-up chemical reaction process. Different techniques employed for the syntheses of inorganic mesoporous solids, like silicas, metal doped silicas, transition and non-transition metal oxides, mixed oxides, metallophosphates, organic-inorganic hybrids as well as purely organic mesoporous materials like carbons, polymers etc. using surfactants are depicted schematically and elaborately in this paper. Moreover, some of the frontline applications of these mesoporous solids, which are directly related to their functionality, composition and surface properties are discussed at the appropriate places.

An improved strategy of quantitative structure-property relationship (QSPR) studies of diverse and inhomogeneous organic datasets has been proposed. A molecular connectivity term was successively corrected for different structural features encoded in fragmental descriptors. The so-called solvation index 1chis (a weighted Randic index) was used as a "leading" variable and standardized molecular fragments were employed as "corrective" class-specific variables. Performance of the new approach was illustrated by modelling a dataset of experimental normal boiling points of 833 organic compounds belonging to 20 structural classes. Firstly, separate QSPR models were derived for each class and for eight groups of structurally similar classes. Finally, a general model formed by combining all the classes together was derived (r2=0.957, s=12.9degreesC). The strategy outlined can find application in QSPR analyses of massive, highly diverse databases of organic compounds.
The Bechtel Hanford, Inc. facility transition instruction was initiated in response to the need for a common, streamlined process for facility transitions and to capture the knowledge and experience that has accumulated over the last few years. The instruction serves as an educational resource and defines the process for transitioning facilities to long-term surveillance and maintenance (S and M). Generally, these facilities do not have identified operations missions and must be transitioned from operational status to a safe and stable configuration for long-term S and M. The instruction can be applied to a wide range of facilities--from process canyon complexes like the Plutonium Uranium Extraction Facility or B Plant, to stand-alone, lower hazard facilities like the 242B/BL facility. The facility transition process is implemented (under the direction of the US Department of Energy, Richland Operations Office [RL] Assistant Manager-Environmental) by Bechtel Hanford, Inc. management, with input and interaction with the appropriate RL division and Hanford site contractors as noted in the instruction. The application of the steps identified herein and the early participation of all organizations involved are expected to provide a cost-effective, safe, and smooth transition from operational status to deactivation and S and M for a wide range of Hanford Site facilities
Full Text Available Those organizations developing team activities need to use new methods of analysis, recruitment and socializing activities. Thus, more concern for human resources (HR management implications upon labour force diversity is generated. The impact of organization structure upon HR management is more obvious within international and multinational organizations. Developing knowledge, abilities and skills becomes a long term task of the organization's employees and managers. Continuous development helps both employees and organizations to reach the targets. HR development is a key factor in motivating and keeping the good employees. It will give the employees the chance to hold high level responsabilities, to have more authority, to set targets and measurement indicators and to work in teams. HR development delegates the employees and increases their loyalty. Globalization and fast exchange of working environment determine organizations to invest more money in HR development. Knowing that HR are the fundamental element in the organization success, it has been considered that by analyzing the strategies of recruitment, selection, employment and integration of the new comers into organization, we will find the solution to acquire and keep the most suitable persons for organization in order to get organizational and individual performances.

Instructor immediacy has been positively associated with many desirable academic outcomes including increased student learning. This study extends existing understanding of instructional immediacy behaviours in elearning by describing postgraduate nursing students' reflections on their own experience. An exploratory, descriptive survey design was used to collect qualitative data. Participants were asked what behaviours or activities help to create rapport or a positive interpersonal connection (immediacy) between students and their online teacher(s). Thematic analysis of the data revealed three main themes: acknowledging and affirming student's personal and professional responsibilities; providing clear and timely information; and utilising rich media. These findings give lecturers insight into instructional strategies they may adopt to increase immediacy in elearning and hence improve student learning outcomes.

The availability of health services in French is not only weak but also inexistent in some regions in Canada. As a result, estimated 78% of more than a million of Francophones living in a minority situation in Canada experience difficulties accessing health care in French. To promote the delivery of health services in French, publicly funded organizations are encouraged to take measures to ensure that French-language services are clearly visible, available, easily accessible, and equivalent to the quality of services offered in English. This study examines the reorganization and management strategies taken by health care organizations in Ontario that provide health services in French. Review and analysis of designation plans of a sample of health care organizations. Few health care organizations providing services in French have concrete strategies to guarantee availability, visibility, and accessibility of French-language services. Implementation of the active offer of French-language services is likely to be difficult and slow. The Ontario government must strengthen collaboration with health care organizations, Francophone communities, and other key actors participating in the designation process to help health care organizations build capacities for the effective offer of French-language services.

Organic-based molecular switches (OMS) are essential components for the ultimate miniaturization of nanoscale electronics and devices. For practical applications, it is often necessary for OMS to be incorporated into functional solid-state materials. However, the switching characteristics of OMS in solution are usually not transferrable to the solid state, presumably because of spatial confinement or inefficient conversion in densely packed solid phase. A promising way to circumvent this issue is harboring the functional OMS within the robust and porous environment of metal-organic frameworks (MOFs) as their organic components. In this feature article, recent research progress of OMS-based MOFs is briefly summarized. The switching behaviors of OMS under different stimuli (e.g., light, redox, pH, etc.) in the MOF state are first introduced. After that, the technological applications of these OMS-based MOFs in different areas, including CO 2 adsorption, gas separation, drug delivery, photodynamic therapy, and sensing, are outlined. Finally, perspectives and future challenges are discussed in the conclusion. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Both prior literature and reported managerial practices have claimed that the Balanced Scorecard is a management tool that can help organizations to effectively implement strategies. In this article, we examine some of the contributions, dilemmas, and limitations of Balanced Scorecards in health care organizations. First, we describe the evolution of Balanced Scorecards from multidimensional performance measurement systems to causal representations of formulated strategies, and analyze the applicability of Balanced Scorecards in health care settings. Next, we discuss several issues under debate regarding Balanced Scorecard adoption in health care organizations. We distinguish between issues related to the design of Balanced Scorecards and those related to the use of these tools. We conclude that the Balanced Scorecard has the potential to contribute to the implementation of strategies through the strategically-oriented performance measurement systems embedded within it. However, effective adoption requires the adaptation of the generic instrument to the specific realities of health care organizations. Full English text available from:www.revespcardiol.org.

Summary Organ transplantation has developed over the past 50 years to reach the sophisticated and integrated clinical service of today through several advances in science. One of the most important of these has been the ability to apply organ preservation protocols to deliver donor organs of high quality, via a network of organ exchange to match the most suitable recipient patient to the best available organ, capable of rapid resumption of life-sustaining function in the recipient patient. This has only been possible by amassing a good understanding of the potential effects of hypoxic injury on donated organs, and how to prevent these by applying organ preservation. This review sets out the history of organ preservation, how applications of hypothermia have become central to the process, and what the current status is for the range of solid organs commonly transplanted. The science of organ preservation is constantly being updated with new knowledge and ideas, and the review also discusses what innovations are coming close to clinical reality to meet the growing demands for high quality organs in transplantation over the next few years.

This report describes the results from application of the Risk-Based Decision Management Approach for Justifying Characterization of Hanford Tank Waste to the organic-nitrate safety issue in Hanford single-shell tanks (SSTs). Existing chemical and physical models were used, taking advantage of the most current (mid-1997) sampling and analysis data. The purpose of this study is to make specific recommendations for planning characterization to help ensure the safety of each SST as it relates to the organic-nitrate safety issue. An additional objective is to demonstrate the viability of the Risk-Based Strategy for addressing Hanford tank waste safety issues

Thin films of self-organized quantum wells of inorganic-organic hybrid perovskites of (C6H9C2H4NH3)2PbI4 are formed from a simple intercalation strategy to yield well-ordered uniform films over centimeter-size scales. These films compare favorably with traditional solution-chemistry-synthesized thin films. The hybrid films show strong room-temperature exciton-related absorption and photoluminescence, which shift with fabrication protocol. We demonstrate the potential of this method for electronic and photonic device applications.

Ordered π-columns and open nanochannels found in covalent organic frameworks (COFs) could render them able to store electric energy. However, the synthetic difficulty in achieving redox-active skeletons has thus far restricted their potential for energy storage. A general strategy is presented for converting a conventional COF into an outstanding platform for energy storage through post-synthetic functionalization with organic radicals. The radical frameworks with openly accessible polyradicals immobilized on the pore walls undergo rapid and reversible redox reactions, leading to capacitive energy storage with high capacitance, high-rate kinetics, and robust cycle stability. The results suggest that channel-wall functional engineering with redox-active species will be a facile and versatile strategy to explore COFs for energy storage. © 2015 WILEY-VCH Verlag GmbH & Co.

Barrier-free (Ohmic) contacts are a key requirement for efficient organic optoelectronic devices, such as organic light-emitting diodes, solar cells, and field-effect transistors. Here, we propose a simple and robust way of forming an Ohmic hole contact on organic semiconductors with a high ionization energy (IE). The injected hole current from high-work-function metal-oxide electrodes is improved by more than an order of magnitude by using an interlayer for which the sole requirement is that it has a higher IE than the organic semiconductor. Insertion of the interlayer results in electrostatic decoupling of the electrode from the semiconductor and realignment of the Fermi level with the IE of the organic semiconductor. The Ohmic-contact formation is illustrated for a number of material combinations and solves the problem of hole injection into organic semiconductors with a high IE of up to 6 eV.
The production, certification, and marketing of organic agriculture developed slowly in the West as a nongovernmental, community-based response to concerns over food safety and the environmental impacts of chemical agriculture. The current emergence of organic agriculture in less-developed nations is following a very different trajectory owing to the presence of an established global market for organic products and the developmental goals of interventionist states. In this paper I examine the...

Hand hygiene has the biggest impact and is the least expensive way to prevent and control health care-associated infections. In this study, we assessed the effectiveness of the multimodal strategy of the World Health Organization to improve health care-associated infection rates, hand hygiene compliance, and the related knowledge of health care professionals in a Brazilian university hospital. We observed the necessity for an alternative approach in hospitals with high staff turnover and low attendance of educational sessions.
