Tremblay, Junior A., Jacques Ibarzabal, and Jean-Pierre L. Savard. "Foraging ecology of black-backed woodpeckers (Picoides arcticus) in unburned eastern boreal forest stands." Canadian Journal of Forest Research 40, no. 5 (May 2010): 991–99. http://dx.doi.org/10.1139/x10-044.
Full textAbstract:
Managed coniferous forest dominates much of the black-backed woodpecker’s ( Picoides arcticus Swainson) breeding range. Despite this, little is known about the fine-scale foraging behaviour of this focal species in unburned managed forest stands in the absence of insect outbreaks. To investigate the foraging substrates used in such a habitat, we employed radio-telemetry to track a total of 27 black-backed woodpeckers. During two successive summers (2005–2006), 279 foraging observations were recorded, most of which were on dying trees, snags, and downed woody debris. Individuals frequently foraged by excavation, suggesting that in the absence of insect outbreaks the black-backed woodpecker forages mainly by drilling. The majority of foraging events occurred on recently dead snags with a mean dbh (±SE) of 18.3 ± 0.4 cm. Our results suggest that in unburned boreal forest stands, substrate diameter and decay class are important predictors of suitable foraging substrates for black-backed woodpeckers. We suggest that conservation efforts aimed at maintaining this dead-wood dependent cavity nesting species within the landscape, should endeavour to maintain 100 ha patches of old-growth coniferous forest. This would ensure the continuous production of a sufficient quantity of recently dead or dying trees to meet the foraging needs of this species.

Full textAbstract:
The current paper attempts to examine the various aspects of the discussion method of teaching at university and its role in enhancing students’ linguistic and academic skills as well as its shortcomings. In Oman, research on English language teaching at universities and colleges show that a considerable number of students who move from secondary schools and join higher education institutions would confront difficulties in using the English language to meet their personal, social, academic, and career needs efficiently and appropriately. The discussion method allows establishing a rapport with students, stimulating their critical thinking and articulating ideas clearly (McKeachie & Svinicki, 2006). It is relatively acceptable among university academics who use it to promote active learning and long-term retention of information (Bonwell, 2000). It could provide students with a platform to contribute to their own learning and would offer the lecturer an opportunity to check students’ understanding of the material (Craven & Hogan, 2001). Critics argue that some problems may show up such as that several participants dominate the discussion sessions while other students may remain passive, and often, resentful (Brookfield & Perskill, 2005). The discussion could also include other signs of limitation such as that it may get off track or that only few students may dominate it during the whole session (Howard, 2015). Hence, the objectives of this research study are to identify students’ views and opinions of the use of the discussion method in teaching English as well as its strengths and weaknesses. The findings showed that majority of respondents indicated that a good opportunity to interact is provided during the discussion and that the lecturer is not the sole authority in class. The implications of this research could be reflected on students’ learning through their participation in class discussion.

Full textAbstract:
Background: Globally, cancer is the second leading cause of death. Low- and middle-income countries (LMICs) especially lack the sufficient healthcare and oncology workforces needed to screen, diagnose and treat individuals with cancer. While traditional academic and training programs designed to produce healthcare professionals in these countries fill a critical role, few programs exist that maintain, develop, and increase the knowledge, skills, and professional performance of current healthcare and oncology workforces. Mentoring partnerships and twinning programs can provide ongoing education and training that strengthen and build workforce capacity and capability for the full scope of cancer care. Aim: The goal is to achieve resource-appropriate multimodality cancer-care using guideline- and protocol-based education and training and also to develop the capability to conduct world quality research. The model utilizes in-person, in-country site visits lasting from several weeks to months and ongoing connectivity through weekly telemedicine video conferences. Methods: The International Cancer Expert Corps (ICEC) and partner organizations are establishing a network of global and multisectoral partnerships that builds human capacity and capability needed to establish sustainable cancer programs that function at world-class standards. The three-fold mentor-mentee approach ( www.iceccancer.org ) is built by 1) enlisting hubs of expertise to include academic medical centers/universities, private practices and an ICEC Central Hub, 2) enrolling the breadth of expert-mentors needed from a university, practice, professional society and interested individuals, and 3) identifying centers in LMICs - clinics/hospitals/and other care delivery sites in underserved areas, and associates - physicians/allied healthcare workers- seeking mentoring and education. Results: Recent implementation of the ICEC 5-Step Progression Plan provides guidance and serves as an assessment tool for measuring progress between the hubs-centers programs and expert-associate. Twinning programs (hubs-ICEC centers) have been established in multiple sites worldwide including in Africa, Asia and Eurasia. Conclusion: Implementation of the ICEC 5-Step Progression Plan provides a platform from which to track the current stages and progress of twinning mentor-mentee programs, and to evaluate new programs. This information guides the programs and also provides metric-based investment in global health. Critically as the skills in associates and ICEC centers grows, they achieve expert-mentor status and centers become hubs to serve the surrounding regions, thereby enabling geometric growth in cancer care to meet the needs of the growing global burden of cancer.

Purpose – The ultimate objective of the any e-Learning system is to meet the specific need of the online learners and provide them with various features to have efficacious learning experiences by understanding their complexities. Any e-Learning system could be much more improved by tracking students commitment and disengagement on that course, in turn, would allow system to have personalized involvements at appropriate times in order to re-engage learners. Motivations play a important role to get back the learners on the track could be done by analyzing of several attributes of the log files. This paper aims to analyze the multiple attributes which cause the learners to disengage from an online learning environment. Design/methodology/approach – For this improvisation, Web based learning system is researched using data mining techniques in education. There are various attributes characterized for the disengagement prediction using web log file analysis. Though, there have been several attempts to include motivating characteristics in e-Learning systems are adapted, presently influence on cognition is acknowledged mostly. Findings – Classification is one of the predictive data mining technique which makes prediction about values of data using known results found from different data sets. To find out the optimal solution for identifying disengaged learners in the online learning systems, Naive Bayesian (NB) classifier with Particle Swarm Optimization (PSO) algorithm is used which will classify the data set and then perform the independent analysis. Originality/value – The experimental results shows that the use of unrelated variables in the class attributes will reduce the accuracy and reliability of a any classification model. However, the hybrid PSO algorithm is clearly more apt to find minor subsets of attributes than the PSO with NB classifier. The NB classifier combined with hybrid PSO feature selection method proves to be the best feature selection capability without degrading the classification accuracy. It is further proved to be an effective method for mining large structural data in much less computation time.

The emergence of the middle class in the Arab world, was different from the emergence of this class in Europe. The difference was not limited to the beginning of this existence, but also extends to its transformations. In the wake of the Arab Spring revolutions, there was considerable debate on the role of the middle class in these revolutions, and this motivated the research on which this paper is based, during the period from February 2011 until May 2013. The paper aims to track civilizational transformations (economic, political, social and cultural) that affect the structure of the Arab middle class since independence until the present, with a focus on the past decade.

Full textAbstract:
Context: Track-cycling team pursuit (TP) is a highly technical effort involving 4 athletes completing 4 km from a standing start, often in less than 240 s. Transitions between athletes leading the team are obviously of utmost importance. Purpose: To perform qualitative video analyses of transitions of world-class athletes in TP competitions. Methods: Videos captured at 100 Hz were recorded for 77 races (including 96 different athletes) in 5 international track-cycling competitions (eg, UCI World Cups and World Championships) and analyzed for the 12 best teams in the UCI Track Cycling TP Olympic ranking. During TP, 1013 transitions were evaluated individually to extract quantitative (eg, average lead time, transition number, length, duration, height in the curve) and qualitative (quality of transition start, quality of return at the back of the team, distance between third and returning rider score) variables. Determination of correlation coefficients between extracted variables and end time allowed assessment of relationships between variables and relevance of the video analyses. Results: Overall quality of transitions and end time were significantly correlated (r = .35, P = .002). Similarly, transition distance (r = .26, P = .02) and duration (r = .35, P = .002) were positively correlated with end time. Conversely, no relationship was observed between transition number, average lead time, or height reached in the curve and end time. Conclusion: Video analysis of TP races highlights the importance of quality transitions between riders, with preferably swift and short relays rather than longer lead times for faster race times.

Full textAbstract:
The aim of this study was to quantify peak age and improvements over the preceding years to peak age in elite athletic contestants according to athlete performance level, sex, and discipline. Individual season bests for world-ranked top 100 athletes from 2002 to 2016 (14,937 athletes and 57,049 individual results) were downloaded from the International Association of Athletics Federations’ website. Individual performance trends were generated by fitting a quadratic curve separately to each athlete’s performance and age data using a linear modeling procedure. Mean peak age was typically 25–27 y, but somewhat higher for marathon and male throwers (∼28–29 y). Women reached greater peak age than men in the hurdles and middle- and long-distance running events (mean difference, ±90% CL: 0.6, ±0.3 to 1.9, ±0.3 y: small to moderate). Male throwers had greater peak age than corresponding women (1.3, ±0.3 y: small). Throwers displayed the greatest performance improvements over the 5 y prior to peak age (mean [SD]: 7.0% [2.9%]), clearly ahead of jumpers, long-distance runners, hurdlers, middle-distance runners, and sprinters (3.4, ±0.2% to 5.2, ±0.2%; moderate to large). Similarly, top 10 athletes showed greater improvements than top 11–100 athletes in all events (1.0, ±0.9% to 1.8, ±1.1%; small) except throws. Women improved more than men in all events (0.4, ±0.2% to 2.9, ±0.4%) except sprints. This study provides novel insight on performance development in athletic contestants that are useful for practitioners when setting goals and evaluating strategies for achieving success.

Full textAbstract:
The purpose of this study was to determine whether world class skiers were alike in their mechanical power outputs (normalized for body mass and velocity and called mechanical cost, MTC) and body segment energy transfers when skiing in competition on level and uphill terrain using the diagonal technique. Eleven competitors were analyzed from film taken during a 15-km World Championship race on a level (1.6°) and uphill (9.0°) section of the course. Metabolic rates were estimated from assumptions concerning the efficiencies of positive and negative work and calculations, from the film, of the mechanical power produced by the skiers. The results showed that skiing on the slope was 2.2 times more demanding mechanically than skiing on a level track (MTC of 4.0 vs. 1.8 J • kg−1• m−1, respectively). Skiers who had high MTC had low energy transfers (r = −0.9). Even in this presumably homogeneous group of elite skiers there were large individual differences in MTC and other mechanical variables, suggesting technique problems for some. Furthermore, on flat terrain the estimated metabolic rate was only about 76% of an MV02of 80 ml • kg−1• min−1. This suggests that speed, using the diagonal stride, may be limited by constraints on body segment utilization and not by the physiological energy delivery system of these highly trained athletes.

Full textAbstract:
As part of an ongoing project to evaluate elite track and field throwers in the United States, the javelin competition was filmed during the 1983 Pepsi Invitational Track Meet. A high-speed video camera (Spin Physics SP2000) was positioned orthogonal to the javelin runway to record the release of all throws. During this competition, Tom Petranoff’s world record (99.72 m) was filmed at 200 fields per second. Subsequent frame-by-frame digitization yielded results consistent with reports in the literature. Release velocity was 32.3 m/s and represents one of the highest values ever reported. Angle of release was .57r, javelin attitude at release was .64r» and angle of attack was .07r. While optimum values for these release parameters, in light of published results, remain open to discussion, the results presented here represent unique information on a world record performance and can serve as a basis of comparison for future performances.

Full textAbstract:
Purpose: Nitrate supplementation can increase tolerance to high-intensity work rates; however, limited data exist on the recovery of performance. The authors tested whether 5 d of nitrate supplementation could improve repeated time-trial performance in speed skating. Methods: Using a double-blind, placebo-controlled, crossover design, 9 international-level short-track speed skaters ingested 1 high (juice blend, ∼6.5 mmol nitrate; HI) or low dose (juice blend, ∼1 mmol nitrate; LO) per day on days 1–4. After a double dose of either HI or LO on day 5, athletes performed 2 on-ice 1000-m time trials, separated by 35 min, to simulate competition races. Differences between HI and LO were compared with the smallest practically important difference. Results: Salivary [nitrate] and [nitrite] were higher in HI than LO before the first (nitrate: 81%, effect size [ES]: 1.76; nitrite: 72%, ES: 1.73) and second pursuits (nitrate: 81%, ES: 1.92; nitrite: 71%, ES: 1.78). However, there was no difference in performance in the first (LO: 90.92 [4.08] s; HI: 90.95 [4.06] s, ES: 0.01) or the second time trial (LO: 91.16 [4.06] s; HI: 91.55 [4.40] s, ES: 0.09). Plasma [lactate] measured after the trials (LO: 14.8 [1.1] mM; HI: 14.8 [1.2] mM, ES: 0.01) and at the end of the recovery period (LO: 9.8 [2.1] mM; HI: 10.2 [1.9] mM, ES: 0.05) was not different between treatments. Conclusion: Five days of high-dose nitrate supplementation did not change physiological responses and failed to improve single and repeated time-trial performances in world-class short-track speed skaters. These data suggest that nitrate ingestion up to 6.5 mmol does not enhance recovery from supramaximal exercise in world-class athletes.

Increasingly, new librarians graduate to face a world of changing technology and new ways of interacting with information. The anxiety of this shifting environment is compounded for tenure-track librarians who must also meet scholarship and instruction requirements that may be unfamiliar to them. One way that librarians can navigate the transition to tenure-track professional positions is to participate in mentoring programs for new academic librarians. This study examines the effectiveness of mentoring programs for novice tenure-track libraries in a variety of library settings, and provides examples of successful academic library mentoring programs already in place with the intent that librarians use the data and findings to construct or improve their own library mentoring programs.

Full textAbstract:
World-class runner Steve Prefontaine died May 30, 1975, at the age of 24. Running during a time of unparalleled track and field popularity, he was a favorite media focus. Incredibly, he regained media attention in the 1990s. Using a critical cultural studies approach, this article explores media accounts of Prefontaine. A 1970s working-class “rebel with a cause,” Prefontaine served as an ideal of White working-class masculinity and as a voice calling for structural changes to the track and field governing body. In the 1990s, with the Nike funded reemergence of Prefontaine, that rebelliousness was recontextualized and co-opted, shifting Prefontaine into a commodified maverick celebrity, embodying the changing ideals of White, classless masculinity and supporting the ideology of individualism in late consumer capitalism.

The article explores the issues of academic excellence in higher education to pursue a position in world-class universities. Two universities in Pakistan have been chosen for the site of this qualitative study, one which has achieved the status, and the other still aspiring. The triangulation has been reached by a document analysis of the quality reports submitted by the two universities, semi-structured interviews with the senior and middle management of the universities, deans, and director for Quality Enhancement Cells, and head of the departments of the selected universities. The primary data obtained have been compared and contrasted with the quality characteristics marked by standards for academic excellence. Research findings inform us that unawareness of the international quality standards, and its potential benefits, the disinterest of university leadership are the main problems, due to which Pakistani universities are lagging behind. The study proposes if proper understanding and meaningfulness is created through quality professionalism, it would become much easier to pursue quality assurance process to meet international standards. The findings of the study will be a unique contribution to the body of literature creating a point of interest to policymakers and quality assurance practitioners of the developing countries who are concerned about the academic excellence of Higher Education Institutions (HEIs) to accentuate in the significant areas which make any university, a world-class university.

Full textAbstract:
This article focuses on the two national internment programs developed in the United States during World War I from the vantage point of Portland, Oregon, and argues that they unfolded locally. Both the male enemy aliens at risk of internment and the girls and women who experienced confinement due to sexual activity tended to be poor. Authorities deemed that they were, or were likely to become, radicals or prostitutes—but that they were not to be prosecuted as such. Officials could banish or track them more easily as threats to the war effort, rather than as threats to urban social stability and economic development. Scholars of the home front have ignored the evolution of local-federal partnerships to track or intern these two groups and have so far failed to establish how local perceptions of the dangerous poor shaped cooperation with wartime federal authority.

Full textAbstract:
Combined with the reconstruction of the existing railway line with speed of 200km/h, a calculation model of bridge-subgrade transition section was developed by the theory of vehicle-track-bridge/subgrade coupling dynamics. The simulation program was compiled, which could be used to calculate and evaluate the dynamic characteristics of transition section in speed-up line. The results of field reconnaissance operations and calculations show that the track structure stiffness in transition section is uneven, or even part of the function fails, which can not meet the requirements of speed-raising. Some measures, such as transition section database establishment, class-based management implementation, separate design and separate reinforcement adoption, can be used for the transition sections, which are listed as the objects of emphatic assessment. In addition, the evaluation system will provide theoretical support and references for design and construction in reconstruction project of transition section.

This paper examines the cyborg identities of 7 elite track and field athletes using a paradigmatic analysis of narratives (Polkinghorne, 1995, 1997). Following a discussion of philosophical and cultural studies conceptualizations of technology, and a brief overview of various types of sport technologies, I present several themes that emerged through an analysis of the collection of stories told by participants during in-depth interviews. In general, while participants engaged with a range of technologies, their stories dealt predominately with the tensions within world-class athletics between modernist notions of the “natural” body and postmodern conceptualizations of corporeality. The paper concludes with comments about the ongoing politics of sporting cyborg bodies and the increasing relevance of cyborg theory to critical sport studies work.

Full textAbstract:
Differences in the utilization of body segment movements between world-class and recreational cross-country skiers which result in a longer stride of the elite were studied using mechanical energy analyses. Nine world-class racers and six recreational skiers (novices) were filmed, the latter while they executed their fastest possible stable diagonal stride on a level track, and the former during competition. A 15-member linked segment model was digitized, the coordinate data filtered at 4.5 Hz and body segment energy curves; mechanical work output and mechanical energy transfers were calculated using the method described by Pierrynowski, Winter, and Norman (1980). The elite skiers exhibited larger exchanges between potential and kinetic energy in all segments during swing phases and all but the upper arm segment during pushing phases. Step-wise discriminant function analysis showed significant differences in the swinging foot, pushing foot, and pushing shank. The differences appear to be largely attributable to the higher leg swings of the experts, who prolong the glide and enhance step length, probably at a relatively lower metabolic cost by exploiting gravity to augment muscular force by generating pendulum-like movements.

The results of this study by using a number of criteria indicate that LPTK has shown dynamics to strive towards world universities. Yet the dynamics are still small and limited, because faced with a certain number of constraints, namely (1) the lack of academic qualifications of teaching staff come from overseas graduates, as required as one of the criteria towards WCU; (2) improving the quality of lecturers is often hindered by foreign language skills, the elderly, funding, and limited provider institution quality graduate programs; (3) sending lecturers to continue their studies abroad are still hanging from the directorate Higher Education; (4) the submission of budgetary limitations that do not provide the flexibility to call / use a guest lecturer / adjunct lecturer who come from abroad; (5) there are many new courses that achieve accreditation status B / C in the assessment of BAN PT, so they concentrated on improving the status of accreditation of the study programs; (6) the reliance fund / budget delivery of education LPTK against the government (APBN), so the lack of flexibility in allocating funds specifically aimed at supporting the WCU program; (7) the appointment of a lecturer / lecturer in LPTK are insufficient to meet the needs, especially in terms of the angle ratio of the number of faculty and students; and (8) lack of journals in college container itself or else outside an accredited institution of national / international lecturers publish scientific papers.

Foreign language is one of the fundamental elements in creating the world class university. To realize a world class university, the excellent Arabic language learning program is necessary to meet the needs of international communication in the internal and external environment of the campus. This study aimed to explore and analyze the Arabic language learning program at UIN Maliki Malang. The research data were obtained from the interview with campus governance and direct observation of Arabic learning program activities and the documentation of strategic planning of Arabic language learning programs to create a world class university. The interviews were conducted with 10 people of campus institution governance. The results showed that Arabic language learning program in realizing a world class university is an implementation of the university's vision which is contained in the development of an integrated curriculum and ulul albab character. The curriculum is designed in the form of a "tree of knowledge" construction. To form solid scientific roots, linguistic strengthening is needed so that its branches and its twigs are strong too. Language strengthening is manifested in the form of the Special Arabic Language Class Program (PKPBA), Ma'had al-jami'ah program and intensive training for educators and educational staff. These findings indicate that the integration of Arabic language learning programs between internal campus institutions is a measure of success in realizing a world class university. The recommendation for further research was to measure the effectiveness of each program at UIN Maliki Malang.

AbstractThe National Oceanic and Atmospheric Administration's Office of National Marine Sanctuaries employs constantly evolving marine technologies to meet its requirements for observing and tracking changing ocean conditions and resource qualities. Vessels, submersibles, and a host of unmanned platforms, including satellites, buoys, remotely operated vehicles, and in-water instrument arrays, are providing information that helps us better understand and manage activities that affect the ocean, Great Lakes, and adjacent coasts. Platforms and sensors track animals and ship traffic, send alerts to at-sea operators, map the seabed and its natural and archaeological resources, track spills, sample water, and define ocean soundscapes. Technologies are also employed to support complex diving operations, record marine life, document shipwrecks, log data, produce map products, and broadcast live feeds to the world. The sanctuaries frequently work with commercial, federal, academic, and nonprofit partners to focus a broad range of observing assets on the many issues of concern to marine conservation and protection.

Full textAbstract:
In recent criticism, arguments about whether domesticity in The Wide, Wide World (1850) empowered or disempowered women, and whether it was embraced or critiqued by Warner and her contemporaries, have been founded upon, or at least buttressed by, readings of horses and horsemanship. The interpretation of Ellen Montgomery's riding lessons as a metaphor for her disempowerment, and the ubiquitous denunciation of John Humphreys as "brutal horse-beater," however, have little grounding in the nineteenth-century horsemanship on which Warner drew. While for centuries horses in Western culture had been associated with human passions and horsemanship with their forcible domination, a combination of new methods for disciplining equines and new forms of recreational riding rendered the equine body, in the nineteenth century, discursively situated to communicate the internalized discipline and self-regulation that was necessary to make a human body middle class. Through horseback riding and other lessons, Ellen attains the particular mental and bodily development necessary for her to become a proper, sentimental, middle-class woman who is inserted into a network of power relations-a network in which Ellen attains power over other kinds of women who fail to meet the standards that she does. Historical contextualization also reveals that John's horsemanship accords quite well with nineteenth-century standards and would not have been seen as abusive by his contemporaries. As nearly all arguments about The Wide, Wide World's resistance to domestic ideology have been predicated upon John's propensity for horse-beating, this essay calls for a reexamination of what has become a principal claim of Warner criticism.

Full textAbstract:
This paper addresses the question of how traditional institutions interact with the forces of globalization to shape the economic mobility and welfare of particular groups of individuals in the new economy. We explore the role of one such traditional institution—the caste system—in shaping career choices by gender in Bombay using new survey data on school enrollment and income over the past 20 years. We find that male working-class—lower-caste—networks continue to channel boys into local language schools that lead to the traditional occupation, despite the fact that returns to nontraditional white-collar occupations rose substantially in the 1990s, suggesting the possibility of a dynamic inefficiency. In contrast, lower-caste girls, who historically had low labor market participation rates and so did not benefit from the network, are taking full advantage of the opportunities that became available in the new economy by switching rapidly to English schools.

A teaching methodology was employed to use gardeners in the community to help in the teaching of a Herbaceous Perennial Plant Identification class (8 weeks, about 160 taxa). Most universities do not have a diverse collection of herbaceous perennials planted on campus, nor do most campuses have horticultural or botanical gardens for students. Teaching plant materials with photos alone or trying to force materials in the greenhouse is not only a horticultural challenge but seldom provides students with the important identification characteristics (habit, fragrance, fruit) of the taxon. Approximately six gardeners in the community agreed to open their private gardens to the students. Plants are evaluated 2 days before class time, and a list of plants is published on WebCT each week All gardens chosen must be within 15 minutes driving time from campus. Students were able to drive to the gardens, meet the gardeners and were exposed to the plants in garden setting. Potential problems of being unable to drive to gardens, or not being able to return to the gardens to study were not realized. Gardeners embraced the program and students were enriched by studying plants in a natural garden environment. The final examination is conducted in one of the gardens visited by the class. The use of gardeners in the community has been an important part of the class for 10 years.

Full textAbstract:
Tuberculosis remains the top 10 causes of death worldwide in 2015, with the largest number of new tuberculosis cases occurring in Asia. Singapore, a high-income Asian country, still has an intermediate tuberculosis burden. This study is to determine Singapore’s tuberculosis policy with regard to achieving tuberculosis elimination goals. This is a case study of tuberculosis elimination policy in Singapore. Data were collected by policy review and literature review. Policy documents and reports were gathered from the websites of the Ministry of Health and the World Health Organization for policy review. The literature review was carried out through PubMed and Google Scholar to identify articles on epidemiology, treatment, and prevention of tuberculosis in Singapore. Data analysis of policy reports revealed that despite the overall downwards trend in the tuberculosis incidence rates between 2000 and 2015, the tuberculosis incidence rates reversed in 2008. Singapore tuberculosis policies are mostly consistent with the World Health Organization Stop TB Strategy, although over half of the performance indicators were not achieved by 2015. After screening 1014 articles, 18 studies were included in the literature review. The rapidly ageing population, great population mobility, and continuous community transmission were found to be major obstacles to achieving Millennium Development Goals in Singapore. Singapore is lagging in achieving the targets. Scaling up the existing tuberculosis programme to accelerate the tuberculosis decline is required to meet Sustainable Development Goals 2030. Unlike other high-income countries with an intermediate tuberculosis burden in Asia, Singapore has increasing tuberculosis incidence rates. While other countries face the burden of an ageing population, Singapore faces an additional burden of an influx of migrants from high-incidence countries. Singapore will need to control tuberculosis in both these demographic groups to reverse the increasing incidence trend.

FATF is such an organization that has been formed in order to scrutinize and control the menace of money laundering and that of the terror financing. In a third world state like Pakistan where there is dearth of transparent mechanisms of money transfers and where there is no rule of law, it has become easy for the individuals to carry out the illicit activities like money laundering (Dube and Vargas, 2013). Pakistan has been in the grey list from the last few years and it has dramatically affected the economy of Pakistan. Pakistan has established a number of centralized mechanisms that are, without a doubt, on the correct track for monitoring the financial transaction system, which is currently very near to meet the certain much needed criteria for finding and freezing the founded and highlighted money laundering cases and that of the terrorist financing.

Full textAbstract:
AbstractPentecostalism first appeared as a global movement, built with both modern and antimodern materials provided by the American holiness missionary movement. On the anti-modern side, radical holiness spirituality and theology infused the worldviews of its advocates with supernaturalism, primitivism, and an apocalyptic eschatology. It resisted modern trends toward systematization, bureaucratization, and centralized control. Furthermore, radical holiness minimized the significance of modern categories of nation, ethnicity, race, and civilization. On the other side, radical holiness depended on the modern disintegration of traditional religious deference, used modern techniques for promoting audiencedriven or democratized patterns of authority, and effectively equipped its followers for the pragmatic methodologies of modernity by skillfully making use of transportation networks, fund-raising techniques, and mass media to reach large audiences.American holiness missionaries carried these characteristics overseas, where non-American advocates adapted them to their particular circumstances. Both American and non-American adherents promoted radical holiness in ways that confounded reigning categories of identity, power relations, and conceptions of East and West. Radical holiness granted religious authority to Chinese men, Indian girls, spirit-filled Zulus, working-class Chileans, female evangelists, and African-American leaders, as well as white American males, without consciously mobilizing its followers along lines of national, ethnic, gendered, racial, or class identity. It demanded that its followers leave "heathenism," but it did so without utilizing the imperialist era discourse of civilization that upheld western cultural superiority and non-western cultural inferiority. In terms of its national or racial characteristics, then, early leaders from diverse backgrounds used tools from the American holiness movement to bring a non-American movement, world Pentecostalism, into existence.

"Tourmaline as a Tracer of Late-Magmatic to Hydrothermal Fluid Evolution: The World-Class San Rafael Tin (-Copper) Deposit, Peru." Economic Geology 115, no. 8 (August 18, 2020): 1665–97. http://dx.doi.org/10.5382/econgeo.4762.
Full textAbstract:
Abstract The world-class San Rafael tin (-copper) deposit (central Andean tin belt, southeast Peru) is an exceptionally large and rich (>1 million metric tons Sn; grades typically >2% Sn) cassiterite-bearing hydrothermal vein system hosted by a late Oligocene (ca. 24 Ma) peraluminous K-feldspar-megacrystic granitic complex and surrounding Ordovician shales affected by deformation and low-grade metamorphism. The mineralization consists of NW-trending, quartz-cassiterite-sulfide veins and fault-controlled breccia bodies (>1.4 km in vertical and horizontal extension). They show volumetrically important tourmaline alteration that principally formed prior to the main ore stage, similar to other granite-related Sn deposits worldwide. We present here a detailed textural and geochemical study of tourmaline, aiming to trace fluid evolution of the San Rafael magmatic-hydrothermal system that led to the deposition of tin mineralization. Based on previous works and new petrographic observations, three main generations of tourmaline of both magmatic and hydrothermal origin were distinguished and were analyzed in situ for their major, minor, and trace element composition by electron microprobe analyzer and laser ablation-inductively coupled plasma-mass spectrometry, as well as for their bulk Sr, Nd, and Pb isotope compositions by multicollector-inductively coupled plasma-mass spectrometry. A first late-magmatic tourmaline generation (Tur 1) occurs in peraluminous granitic rocks as nodules and disseminations, which do not show evidence of alteration. This early Tur 1 is texturally and compositionally homogeneous; it has a dravitic composition, with Fe/(Fe + Mg) = 0.36 to 0.52, close to the schorl-dravite limit, and relatively high contents (10s to 100s ppm) of Li, K, Mn, light rare earth elements, and Zn. The second generation (Tur 2)—the most important volumetrically—is pre-ore, high-temperature (>500°C), hydrothermal tourmaline occurring as phenocryst replacement (Tur 2a) and open-space fillings in veins and breccias (Tur 2b) and microbreccias (Tur 2c) emplaced in the host granites and shales. Pre-ore Tur 2 typically shows oscillatory zoning, possibly reflecting rapid changes in the hydrothermal system, and has a large compositional range that spans the schorl to dravite fields, with Fe/(Fe + Mg) = 0.02 to 0.83. Trace element contents of Tur 2 are similar to those of Tur 1. Compositional variations within Tur 2 may be explained by the different degree of interaction of the magmatic-hydrothermal fluid with the host rocks (granites and shales), in part because of the effect of replacement versus open-space filling. The third generation is syn-ore hydrothermal tourmaline (Tur 3). It forms microscopic veinlets and overgrowths, partly cutting previous tourmaline generations, and is locally intergrown with cassiterite, chlorite, quartz, and minor pyrrhotite and arsenopyrite from the main ore assemblage. Syn-ore Tur 3 has schorl-foititic compositions, with Fe/(Fe + Mg) = 0.48 to 0.94, that partly differ from those of late-magmatic Tur 1 and pre-ore hydrothermal Tur 2. Relative to Tur 1 and Tur 2, syn-ore Tur 3 has higher contents of Sr and heavy rare earth elements (10s to 100s ppm) and unusually high contents of Sn (up to >1,000 ppm). Existence of these three main tourmaline generations, each having specific textural and compositional characteristics, reflects a boron-rich protracted magmatic-hydrothermal system with repeated episodes of hydrofracturing and fluid-assisted reopening, generating veins and breccias. Most trace elements in the San Rafael tourmaline do not correlate with Fe/(Fe + Mg) ratios, suggesting that their incorporation was likely controlled by the melt/fluid composition and local fluid-rock interactions. The initial radiogenic Sr and Nd isotope compositions of the three aforementioned tourmaline generations (0.7160–0.7276 for 87Sr/86Sr(i) and 0.5119–0.5124 for 143Nd/144Nd(i)) mostly overlap those of the San Rafael granites (87Sr/86Sr(i) = 0.7131–0.7202 and 143Nd/144Nd(i) = 0.5121–0.5122) and support a dominantly magmatic origin of the hydrothermal fluids. These compositions also overlap the initial Nd isotope values of Bolivian tin porphyries. The initial Pb isotope compositions of tourmaline show larger variations, with 206Pb/204Pb(i), 207Pb/204Pb(i), and 208Pb/204Pb(i) ratios mostly falling in the range of 18.6 to 19.3, 15.6 to 16.0, and 38.6 to 39.7, respectively. These compositions partly overlap the initial Pb isotope values of the San Rafael granites (206Pb/204Pb(i) = 18.6–18.8, 207Pb/204Pb(i) = 15.6–15.7, and 208Pb/204Pb(i) = 38.9–39.0) and are also similar to those of other Oligocene to Miocene Sn-W ± Cu-Zn-Pb-Ag deposits in southeast Peru. Rare earth element patterns of tourmaline are characterized, from Tur 1 to Tur 3, by decreasing (Eu/Eu*)N ratios (from 20 to 2) that correlate with increasing Sn contents (from 10s to >1,000 ppm). These variations are interpreted to reflect evolution of the hydrothermal system from reducing toward relatively more oxidizing conditions, still in a low-sulfidation environment, as indicated by the pyrrhotite-arsenopyrite assemblage. The changing textural and compositional features of Tur 1 to Tur 3 reflect the evolution of the San Rafael magmatic-hydrothermal system and support the model of fluid mixing between reduced, Sn-rich magmatic fluids and cooler, oxidizing meteoric waters as the main process that caused cassiterite precipitation.

A regional policy is one of the important tools of supporting the state territorial integrity. Approaches and principles applied, and methods and tools employed are directly dependent on the historical track and socio-economic reality within a country, as well as on the geopolitical situation in the world. A regional policy of any contemporary state, including the Russian State, should take into account the challenges engendering threats to the national safety and territorial integrity of a country under the turbulent conditions and in the situation of the world order re-formatting. The basic concepts of a regional policy in the geopolitical turbulence circumstances should be guided by the strategic goal of preserving the national unity. Use of affirmative action within the regional policy of contemporary states, according to the authors’ opinion, engenders some threat to the territorial integrity because it generates certain prerequisites for separatism. The analysis of the cases of affirmative action used by some foreign states within the framework of their regional policy helps to estimate potential threats that the Russian State can meet with while realizing its regional policy.

Anemia is a multifactorial condition, with a complex etiology that involves nutritional and non-nutritional factors. The misconception that iron deficiency is equivalent to anemia may mask the need to address other potential causative factors. This review paper aims to (1) assess the burden of anemia vs. iron deficiency anemia (IDA) amongst women of reproductive age (WRA), pregnant women (PW), and children under five years old (underfive children, U5C) in the Eastern Mediterranean region (EMR); (2) evaluate trends in anemia prevalence and whether countries are on track towards meeting the World Health Assembly (WHA) target for 2025; and (3) characterize anemia reduction efforts and provide a road map for future programs. A search of pertinent literature and databases was conducted. Anemia prevalence in the EMR ranged between 22.6% and 63% amongst PW, 27% and 69.6% amongst WRA, and 23.8% and 83.5% amongst U5C. Data showed that the EMR is not on course towards meeting the WHA target. The contribution of IDA to anemia was found to be less than half. Other potential contributors to anemia in the region were identified, including micronutrient deficiencies, parasitic infestations, and poor sanitation. A framework of action was proposed as a roadmap to meet the targets set by the WHA.

Internships have been shown to be impactful tools to connect students’ learning in academia with real-world industrial needs. To help the students to get more out of their internship experience, some universities provide a summer internship class in which students do class assignments based on their experiences during their internship. There have been numerous studies on the benefits of internships. However, the benefits of a potential internship class for students in construction management (CM) programs at universities have not yet been investigated. This paper demonstrates the structure of an interview-based internship class and investigates its effectiveness. We have focused on the CM program at the University of Nebraska-Lincoln (UNL) as a case study. We sent online questionnaires to the intern students who took the class, students’ mentors, and the professors who taught the class. The results indicate that despite some challenges to meet the requirements of the class, the students, their mentors, and the professor found the class beneficial. The results of this paper are expected to help CM programs with the establishment and improvement of internship classes in their curriculum.

Full textAbstract:
GNSS information is vulnerable to external interference and causes failure when unmanned aerial vehicles (UAVs) are in a fully autonomous flight in complex environments such as high-rise parks and dense forests. This paper presents a pan-tilt-based visual servoing (PBVS) method for obtaining world coordinate information. The system is equipped with an inertial measurement unit (IMU), an air pressure sensor, a magnetometer, and a pan-tilt-zoom (PTZ) camera. In this paper, we explain the physical model and the application method of the PBVS system, which can be briefly summarized as follows. We track the operation target with a UAV carrying a camera and output the information about the UAV’s position and the angle between the PTZ and the anchor point. In this way, we can obtain the current absolute position information of the UAV with its absolute altitude collected by the height sensing unit and absolute geographic coordinate information and altitude information of the tracked target. We set up an actual UAV experimental environment. To meet the calculation requirements, some sensor data will be sent to the cloud through the network. Through the field tests, it can be concluded that the systematic deviation of the overall solution is less than the error of GNSS sensor equipment, and it can provide navigation coordinate information for the UAV in complex environments. Compared with traditional visual navigation systems, our scheme has the advantage of obtaining absolute, continuous, accurate, and efficient navigation information at a short distance (within 15 m from the target). This system can be used in scenarios that require autonomous cruise, such as self-powered inspections of UAVs, patrols in parks, etc.

Full textAbstract:
To effectively mitigate global greenhouse gas emissions, both industrialized and developing countries should participate in the energy transition that to replace fossil fuels with renewable energy. Multilateral development banks (MDBs) have been scaling up their renewable energy finance to developing countries to help them achieve their renewable energy targets. This study examines the evolution of energy financing of the World Bank, the oldest and largest MDB, by reviewing and estimating its sector-specific energy investments made over the last 35 years (1985–2019). The results confirm that the World Bank is on the right track supporting energy transition in developing countries, overall; however, limitations exist. While the share of investments in non-hydro renewable energy (NHRE) in the World Bank’s total energy finance was expanded from 1% (1985–1990) to 16.5% (2011–2019), the share of fossil fuels contracted from 51.8% (1985–1990) to 15.2% (2011–2019). However, commitments to fossil fuels have been sustained, but financing for NHRE—US$1.2 billion per year after the adoption of the Paris Agreement—is still insufficient to meet demand. Moreover, NHRE finance tended to be concentrated in middle-income developing countries. To accelerate the energy transition in developing countries, the World Bank needs to increase NHRE finance with more support for low-income countries while reducing fossil fuel finance.

Delay tolerant networks (DTNs) represent a class of intermittently connected networks. In such networks, messages are hard to track since they are transmitted by opportunistic encounters between mobile nodes. This feature makes DTN an appropriate masking channel for information hiding systems. However, the DTN often has poor communication quality, given that it suffers from frequent disruptions. In order to improve the communication quality of DTN and meet the needs of information hiding system, an efficient routing strategy is proposed in this article. On the other hand, in information hiding systems, a relatively long Time-To-Live (TTL) of messages will increase the risk of the message being exposed. To achieve a balance between delivery ratio and concealment, the sensitivity of message TTL is analyzed and a suitable value of lifetime is given. Finally, the simulation results show that the proposed algorithm can improve the effectiveness of message transmission, and the DTN can be used as masking channel to realize information hiding system.

Full textAbstract:
Background: Injury surveillance systems have been implemented at world championships, yet no previous work has determined the burden of injuries during the United States Track and Field Olympic Trials. Additionally, the type of medical service providers utilized throughout the meet has not been reported, leaving it unclear whether optimal staffing needs are being met. Purpose: To describe the incidence of injuries presenting to the medical team at the 2016 US Track and Field Olympic Trials (Eugene, Oregon) by event type and competitor demographics. Study Design: Descriptive epidemiology study. Methods: A retrospective review was performed of all documented injuries and treatments recorded from June 28 through July 10, 2016. Descriptive statistics and the prevalence of newly incurred injuries were calculated for registered athletes and nonathlete (ie, support) staff. The incidence of acute injuries was analyzed for registered athletes, as stratified by athlete sex and event type. Results: A total of 514 individuals were seen during the trials: 89% were athletes and 11% were supporting staff. Physicians treated 71 injuries and 14 illnesses. Of diagnosed injuries, 85% (n = 60) occurred among athletes, with hamstring strains (16.7%, n = 10) being the most prevalent. A mean of 124 medical services (median, 137; interquartile range, 65.5-179.5) were provided each day of the trials. Among medical services, 41.8% were attributed to massage therapists for athletes, while chiropractic services were the most utilized service (47.1%) by the support staff. There was an overall incidence of 59.7 injuries per 1000 registered athletes, with jumpers (109.4 per 1000) and long-distance athletes (90.4 per 1000) being the most commonly seen athletes. Conclusion: Throughout the trials, athletes participating in jumping and long-distance events were the most commonly seen by physicians, creating the potential need for an increase in staffing of physicians during meet periods when these events occur. The provided medical services appeared to follow the number of athletes competing during the trials and the need for recovery treatments after competition. Findings from this study should inform future strategy for staffing and policy development at Olympic Trials and other elite-level track and field events in the United States.

Auckland Town Hall, one of New Zealand's premier heritage buildings, was constructed around 1911 to provide Auckland with a world class concert venue and Civic Centre. Constructed of unreinforced masonry the building does not meet with today's seismic protection standards, particularly as a place of assembly. The owner of the building, Auckland City Council, determined that the building should be strengthened as part of an overall restoration programme. This paper describes the standards of strengthening adopted, the analysis and the strengthening systems utilised and is presented and published with the courtesy of Auckland City Council.

The need to inculcate generic skills into graduates to meet the demands of the ever dynamic workplace has been of concern to stakeholders in education and the world of work. This concept of a global competitiveness, and generic skills were reviewed and discussed. This paper also examined the importance of generic skills; and factors influencing generic skills development among graduates were highlighted. This factors calls for different approaches and shift in pedagogy in developing generic skills for global competitiveness which include: change in instructional delivery, from the traditional method of instruction to cooperative learning model. It also involves integration and contextualized learning, creating world class spaces for learning, enhanced utilization of technology and inclusive learning and teaching environment for producing global workers in building technology.
