    Berch, Daniel B

    2016-07-18

    In this commentary, I examine some of the distinctive, foundational difficulties in learning fractions and other types of rational numbers encountered by students with a mathematical learning disability and how these differ from the struggles experienced by students classified as low achieving in math. I discuss evidence indicating that students with math disabilities exhibit a significant delay or deficit in the numerical transcoding of decimal fractions, and I further maintain that they may face unique challenges in developing the ability to effectively translate between different types of fractions and other rational number notational formats-what I call conceptual transcoding I also argue that characterizing this level of comprehensive understanding of rational numbers as rational number sense is irrational, as it misrepresents this flexible and adaptive collection of skills as a biologically based percept rather than a convergence of higher-order competencies that require intensive, formal instruction.

    Today's global communities of users expect quality of service from distributed Grid systems equivalent to that their local data centers. This must be coupled to ubiquitous access to the ensemble of processing and storage resources across multiple Grid infrastructures. We are still facing significant challenges in meeting these expectations, especially in the underlying security, a sustainable and successful economic model, and smoothing the boundaries between administrative and technical domains. Using the Open Science Grid as an example, I examine the status and challenges of Grids operating in production today.

    Full Text Available The ESP teacher has to face certain challenges in his profession: One of the biggest challenges of the ESP teacher is the fact that he/she lacks the necessary knowledge of the subject to teach Business English, for instance, some researchers believing that such courses should be taught by subject teachers. The task of teaching ESP by ESL teachers is not an easy one. Dudley- Evans and St. John pointed out its complexity, identifying five key roles of the ESP practitioner: teacher, course designer and materials provider, collaborator, researcher and evaluator and this is probably the biggest challenge of the profession. The ESP practitioner has also to be aware of the fact that using a foreign language for workplace or study purposes requires not only linguistic proficiency and knowledge but also knowledge of work –related and disciplinary concepts.Last but not least, another challenge for the ESP practitioner is the use of technology in class, a valuable tool for helping with traditional forms of teaching and for creating new forms of communicating.Thus, the ESP practitioner has many things in common with the teacher of general English: he has to be familiar with linguistic development and teaching theories ,he has to be aware of contemporary ideas related to his position and role and he has to become familiar with the new technologies which can be used to improve his methodology.However,his role is more complex than that of a General English teacher.

  7. Facing the challenge of multimorbidity

    Full Text Available Abstract Multimorbidity is a major public health challenge that is rising up the political and health agenda at an accelerated rate. Although the prevalence of multimorbidity increases with age, more than half of the population with multimorbidity are under the age of 65 years [1], with social deprivation a key determinant of multimorbidity in young and middle-aged adults [2,3]. From an individual’s perspective, multimorbidity reduces life expectancy [4–6], decreases physical functioning and quality of life [7], and increases the risk of depression and other mental health disorders [3]. From a healthcare provider’s perspective, multimorbidity is associated with increased health service use, a high risk of emergency and other hospital admissions, high rates of polypharmacy, and spiralling costs [8]. Current health systems, which are typically built around a single-disease framework, are poorly adapted to cope with patients with multimorbidity, who typically experience fragmented healthcare services, leading to potentially inefficient and ineffective care. It is increasingly clear that we need to change our perspective on multimorbidity in order to address it as a specific condition that requires tailored solutions and approaches. The urgent need to tackle multimorbidity in a more strategic, holistic, and cost-effective manner was evident at the 18th European Health Forum Gastein, a leading annual health policy event in the European Union (EU, held in the autumn of 2015. This Forum attracted policymakers, clinicians, health service managers, patients, and a broad range of other stakeholders, all of whom were invited to attend a session entitled “Facing the Challenge of Multimorbidity”.

    This study aims to identify other challenges besides those already faced by students, in seven polytechnics in Malaysia as a continuation to the previous research that had identified 52 main challenges faced by students using the Rasch Model. The explorative study focuses on the challenges that are not included in the Mooney Problem Checklist (MPCL). A total of 121 polytechnic students submitted 183 written responses through the open questions provided. Two hundred fifty two students had responded from a students' perspective on the dichotomous questions regarding their view on the challenges faced. The data was analysed qualitatively using the NVivo 8.0. The findings showed that students from Politeknik Seberang Perai (PSP) gave the highest response, which was 56 (30.6%) and Politeknik Metro Kuala Lumpur (PMKL) had the lowest response of 2 (1.09%). Five dominant challenges were identified, which were the English language (32, 17.5%), learning (14, 7.7%), vehicles (13, 7.1%), information technology and communication (ICT) (13, 7.1%), and peers (11, 6.0%). This article, however, focus on three apparent challenges, namely, English language, vehicles, as well as computer and ICT, as the challenges of learning and peers had been analysed in the previous MPCL. The challenge of English language that had been raised was regarding the weakness in commanding the aspects of speech and fluency. The computer and ICT challenge covered the weakness in mastering ICT and computers, as well as computer breakdowns and low-performance computers. The challenge of vehicles emphasized the unavailability of vehicles to attend lectures and go elsewhere, lack of transportation service in the polytechnic and not having a valid driving license. These challenges are very relevant and need to be discussed in an effort to prepare polytechnics in facing the transformational process of polytechnics.

    Full Text Available Purpose and Objective: The South African automotive component industry faces huge challenges in a very competitive global market. The primary focus of this research article is to determine the challenges facing exporters within this industry with special reference to selected sub-sectors. The challenges are approached from a supply chain perspective only. Problem Investigated: The research problem of this study was to identify these unique challenges and ascertain whether the implementation of a 'philosophy of continuous improvement' could be used as a strategic tool to address the challenges they face in the market. Methodology: This study included a combination of literature review, interviews with managers in the selected sub-groups and questionnaires sent out to determine the challenges facing automotive component exporters. In order to test the content validity and the reliability of the questionnaire, a pilot study was conducted at two organisations that are the main suppliers of automotive filters for passenger vehicles. The non-probability convenience sample technique was used to select the sample and consisted of selected sub-sectors that contribute 64,1% of the total value of automotive component exports in South Africa. Out of twenty-seven questionnaires sent out, twenty (74% response rate were duly completed by the respondents and returned to the researcher. Findings: South Africa faces unique challenges and these are listed and ranked according to priority from most to least important as follows: 1. The reduction of production costs; 2. R/US$ exchange rate effect on the respondent's export sales and profit margin; 3. Exchange rate fluctuations; 4. Threats to the local automotive component market; and 5. Increased competition by way of manufactured imports being sold in the South African market. Value of Research: The study provides recommendations that can be used within the automotive component industry.

  17. Supreme Court rejects challenge to FACE.

    Science.gov (United States)

    1996-10-25

    On October 7, the US Supreme Court declined to hear Skott vs. US, a case challenging the Freedom of Access to Clinic Entrances Act (FACE). The 1994 law makes it a federal crime to use or attempt to use force, threat of force, or physical obstruction to injure, intimidate, or interfere with reproductive health care providers and their patients. The case came to the High Court after the US Court of Appeals for the Seventh Circuit overturned an earlier district court ruling and upheld the constitutionality of the federal statute in December 1995. Six Wisconsin anti-choice protestors, who had been arrested in September 1994 after participating in a blockade of a Milwaukee women's health facility, had successfully petitioned the US District Court for the Eastern District of Wisconsin to dismiss criminal charges based on FACE. While the district court held that Congress had no authority under the Commerce Clause or under the Fourteenth Amendment of the US Constitution to enact FACE, the appellate panel found that the lower court had not given sufficient consideration to congressional findings that the activities restricted by FACE substantially affect interstate commerce and are subject to the regulatory power of Congress. FACE has been upheld by the US Courts of Appeal for the Fourth, Eighth, and Eleventh Circuits and eleven federal district courts. Two district courts have found the law invalid. This marks the third time the High Court has refused to hear a challenge to the law.

  19. The Face Management Challenges of Sport Celebrity

    Directory of Open Access Journals (Sweden)

    Diana-Luiza DUMITRIU

    2015-03-01

    Full Text Available While gaining centrality within the sport field, media accelerated its commodification process and facilitated sport actors becoming competitive on the celebrity market. The aim of this paper is to discuss the reconfiguration that the celebrity logic brought in terms of the mere condition of the sport actor and the face management challenges and remedial strategies that he has to cope with. I will thus focus on two main dimensions that I find to be constitutive for the celebrity status: one related to the augmented media exposure that sport stars are subject to and to the corollary symbolic reconfiguration of the boundaries between his public and his private life, and the second one related to the vulnerability that comes along with the new visibility of the complex repertoire of identities and social roles performed by the sport actors. Within this last dimension of the sport-related celebrity cycle of promotion, I will lay stress not only on the face threatening aspects for the sport stars, but also on the vulnerability transfer within the affinal branding network and the challenges it could bring for the brands that chose to associate their image with a sport celebrity. Thus, I argue that the kaleidoscopic public figures of sport celebrities requires high impression management involvement on their part, as well as more caution on the marketeers part.

  2. Four Challenges That Global Health Networks Face

    Directory of Open Access Journals (Sweden)

    Jeremy Shiffman

    2017-04-01

    Full Text Available Global health networks, webs of individuals and organizations with a shared concern for a particular condition, have proliferated over the past quarter century. They differ in their effectiveness, a factor that may help explain why resource allocations vary across health conditions and do not correspond closely with disease burden. Drawing on findings from recently concluded studies of eight global health networks—addressing alcohol harm, early childhood development (ECD, maternal mortality, neonatal mortality, pneumonia, surgically-treatable conditions, tobacco use, and tuberculosis—I identify four challenges that networks face in generating attention and resources for the conditions that concern them. The first is problem definition: generating consensus on what the problem is and how it should be addressed. The second is positioning: portraying the issue in ways that inspire external audiences to act. The third is coalition-building: forging alliances with these external actors, particularly ones outside the health sector. The fourth is governance: establishing institutions to facilitate collective action. Research indicates that global health networks that effectively tackle these challenges are more likely to garner support to address the conditions that concern them. In addition to the effectiveness of networks, I also consider their legitimacy, identifying reasons both to affirm and to question their right to exert power.

It is characterized by a craving for physical training, resulting in uncontrollable excessive exercise behavior with harmful consequences, such as injuries and impaired social relations. It has not been accepted as a mental disorder in either International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders. The aim of this literature review was to critically examine the research on links (comorbidity, risks (negative consequences, and challenges faced (problems in a treatment context. This review found that compulsive exercise is associated with eating disorder pathology, perfectionism, neuroticism, narcissism, and obsessive compulsive traits. The most prominent negative consequences were injuries, social impairment, and depression, but more research is needed to uncover the potential dysfunction resulting from compulsive exercise. As the condition is not recognized as a psychiatric disorder, studies on treatment interventions are sparse. Problems with compliance have been reported; therefore, motivational interviewing has been proposed as a treatment approach, in combination with cognitive behavioral therapy. This review summarizes and discusses findings on links/comorbidity, risks/negative consequences, and treatment challenges. We suggest that future studies should pay attention to both prevention and counseling in sports settings, where compulsive exercise

  5. Droughts and water scarcity: facing challenges

    Science.gov (United States)

    Pereira, Luis S.

    2014-05-01

    Water scarcity characterizes large portions of the world, particularly the Mediterranean area. It is due to natural causes - climate aridity, which is permanent, and droughts, that are temporary - and to human causes - long term desertification and short term water shortages. Droughts aggravate water scarcity. Knowledge has well developed relative to all processes but management tools still are insufficient as well as the tools required to support appropriate planning and management. Particularly, new approaches on tools for assessing related impacts in agriculture and other economic and social activities are required. Droughts occur in all climates but their characteristics largely differ among regions both in terms frequency, duration and intensity. Research has already produced a large number of tools that allow appropriate monitoring of droughts occurrence and intensity, including dynamics of drought occurrence and time evolution. Advances in drought prediction already are available but we still are far from knowing when a drought will start, how it will evolve and when it dissipates. New developments using teleconnections and GCM are being considered. Climate change is a fact. Are droughts occurrence and severity changing with global change? Opinions are divided about this subject since driving factors and processes are varied and tools for the corresponding analysis are also various. Particularly, weather data series are often too short for obtaining appropriate answers. In a domain where research is producing improved knowledge and innovative approaches, research faces however a variety of challenges. The main ones, dealt in this keynote, refer to concepts and definitions, use of monitoring indices, prediction of drought initiation and evolution, improved assessment of drought impacts, and possible influence of climate change on drought occurrence and severity.

  9. Next-generation proteomics faces new challenges in environmental biotechnology.

    Science.gov (United States)

    Armengaud, Jean

    2016-04-01

    Environmental biotechnology relies on the exploration of novel biological systems and a thorough understanding of the underlying molecular mechanisms. Next-generation proteomics based on the latest generation of mass analyzers currently allows the recording of complete proteomes from any microorganism. Interpreting these data can be straightforward if the genome of the organism is established, or relatively easy to perform through proteogenomics approaches if a draft sequence can be obtained. However, next-generation proteomics faces new, interesting challenges when the organism is distantly related to previously characterized organisms or when mixtures of organisms have to be analyzed. New mass spectrometers and innovative bioinformatics tools are reshaping the possibilities of homology-based proteomics, proteogenomics, and metaproteomics for the characterization of biological systems. Novel time- and cost-effective screening strategies are also possible with this methodology, as exemplified by whole proteome thermal profiling and subpopulation proteomics. The complexity of environmental samples allows for unique developments of approaches and concepts.

    Full Text Available Photosynthetic organisms, and especially cyanobacteria, hold great promise as sources of renewably-produced fuels, bulk and specialty chemicals, and nutritional products. Synthetic biology tools can help unlock cyanobacteria’s potential for these functions, but unfortunately tool development for these organisms has lagged behind that for S. cerevisiae and E. coli. While these organisms may in many cases be more difficult to work with as ‘chassis’ strains for synthetic biology than certain heterotrophs, the unique advantages of autotrophs in biotechnology applications as well as the scientific importance of improved understanding of photosynthesis warrant the development of these systems into something akin to a ‘green E. coli’. In this review, we highlight unique challenges and opportunities for development of synthetic biology approaches in cyanobacteria. We review classical and recently developed methods for constructing targeted mutants in various cyanobacterial strains, and offer perspective on what genetic tools might most greatly expand the ability to engineer new functions in such strains. Similarly, we review what genetic parts are most needed for the development of cyanobacterial synthetic biology. Finally, we highlight recent methods to construct genome-scale models of cyanobacterial metabolism and to use those models to measure properties of autotrophic metabolism. Throughout this paper, we discuss some of the unique challenges of a diurnal, autotrophic lifestyle along with how the development of synthetic biology and biotechnology in cyanobacteria must fit within those constraints.

    The path of society evolution has long been associated with a growing demand for natural resources and continuous environmental degradation. During the last decades, this pace has accelerated considerably, despite the general concern with the legacy being left for the next generations. Looking ahead, the predicted growth of the world population, and the improvement of life conditions in most regions, point to an increasing demand for energy generation, resulting in additional pressure on the Earth's sustainability. Materials have had a key role in decreasing the use of natural resources, by either improving efficiency of existing technologies or enabling the development of radical new ones. The greenhouse effect (CO2 emissions) and the energy crisis are global challenges that can benefit from the development of new materials for the successful implementation of promising technologies and for the imperative replacement of fossil fuels by renewable sources.

    Full Text Available Point of view, preferences and priorities of quality inspection in modern production systems have changed. Quality inspection in its activities is no longer limited only to the documentation of the past, nor is it seen solely as a tool for the detection of nonconformity. Nowadays, the most important quality inspection function is prevention, whose most important goal is to make it before nonconformity. What is expected from modern quality inspection is that it actively improves the production and quality as well as reduces the costs. The aim of the article is to present requirements, guidelines and challenges in the organization of modern quality inspection in a manufacturing company. The role of quality inspection in the classical model and modern model of quality improvement was presented. Determinants of effective quality inspection were presented, as well. The quality inspection methods that best fit into the paradigm of modern quality inspection, that is source inspection, together with visual management were pointed out.

  4. Challenges facing the development of cancer vaccines.

    Fishman, Mayer

    2014-01-01

    Just like any other effective immunization in medicine, cancer vaccines need to have antigens with particular specificity and immunostimulatory features, the immune responses to be elicited in the body, and therapeutic effect-regression or prevention of the cancer-must be meaningful and clinically observable. There are many choices for cancer antigens, such as tissue-specific proteins, cancer-specific proteins, class I- or class II-restricted peptides derived from those, or in situ and whole-cell-derived products are some examples. Another translational issue is that cancer patients are heterogeneous with respect to the extent to which the immune system is already activated with potential to impact the tumor growth or, conversely, the extent to which the immune system has been impaired through a prior and ongoing interaction with the tumor. Conventional or immunologic tests have potential to define a subset of patients with better chance or response, so that particular vaccines can be tested. Treatment of cancer patients is expensive, and trials are slow. To meet these challenges in practical terms will require not only careful scientific technical work for product development, coordination with clinicians to define patient subsets with diseases that can show responses, but also a comprehensive, practical implementation so that we can unlock the full potential of anticancer vaccines.

  5. The art museum facing the memory challenge

    2012-04-01

    Full Text Available Museums have emerged as a representative synthesis of a reality, so a question rises about the preservation of the memories inherent to the functional and symbolic objects. In the particular case of art museums, the goal was to build a heritage repository which would contribute to the creation of a cultural identity. So, the objects were mainly evaluated in terms of aesthetic excellence of its parameters, to the detriment of other meanings. On the other hand, also the historiography of art favored formal aspects, establishing authorities and styles. These circumstances determined the decontextualization of the object in the museum. In return, from mid-twentieth century onwards, the studies of the public, as a plural and diversified entity, and the theoretical debates around the meaning of the object, contributed to a redefinition of the museological speech. The museum had to offset losses due to the musealisation through a set of procedures and tools that recontextualize the meanings of the object in their multiple valences. Between the two vectors, decontextualization and recontextualization, the museum challenges our personal and collective memory.

    While the potential of patient-centered medical homes (PCMH) is promising, little is known empirically about the frontline challenges that primary care (PC) leaders face before making the decision to implement PCMH, let alone in making it a reality. Prior to the design and implementation of the Veterans Health Administration's (VA) national PCMH model--Patient Aligned Care Teams (PACT)--we identified the top challenges faced by PC directors and examined the organizational and area level factors that influenced those challenges. A national cross-sectional key informant organizational survey was fielded to the census of PC directors at VA medical centers and large community-based outpatient clinics (final sample n = 229 sites). PC directors were asked to rate the degree to which they faced 48 management challenges in eight PCMH-related domains (access, preventive care, chronic diseases requiring care in PC, challenging medical conditions, mental health/substance abuse, special populations, PC coordination of care, and clinical informatics). Responses were dichotomized as moderately-to-extremely challenging versus somewhat-slightly-not at all challenging. Items were rank ordered; chi square or regression techniques were used to examine variations in facility size, type, urban/rural location, and region. On average, VA PC directors reported 16 moderate-to-extreme challenges, and the top 20 challenges spanned all eight PCMH domains. Four of the top 20 challenges, including the top two challenges, were from the clinical informatics domain. Management of chronic non-malignant pain requiring opiate therapy was the third most reported challenge nationwide. Significant organizational and area level variations in reported challenges were found especially for care coordination. Better understanding of PC challenges ahead of PCMH implementation provides important context for strategic planning and redesign efforts. As a national healthcare system, the VA provides a unique

    Full Text Available Higher education refers to the subsequent training to high school education; that is undergraduate and graduate; whose mission is to preserve; develop and disseminate culture. Throughout the history of higher education it has undergone a process of transformation; mainly due to the development of knowledge and the transformation of society. In the process they highlighted two great moments; in the first; which culminated in the mid-twentieth century; it conceived the higher education institution encompassing all knowledge of society; and who graduated was ready to perform professionally throughout life; the second time; after those dates; it is conceivable that knowledge is no longer exclusive to the institution of higher education; and there can be no efficient performance without continuous training and continuous updating of knowledge. The objective of this work is to point out the general goals and some strategies of the students’ formation of superior education; to confront the big challenges that it faces today the society. To define this goals and strategies four challenge levels are considered: a physical; structural and politicalideological challenges; b challenges around the scientifictechnician and of the knowledge advances; c challenges of the internal structure of the formative process and the access to the superior education; and d challenges in the formation of values in the students. 

  3. A Variety of Diversity: Facing Higher Education's Educational Challenges

    First among the many important challenges facing American higher education is the need to improve the effectiveness of our educational programs. Public concern has heightened the sense of urgency for colleges and universities to make progress on improving and measuring educational outcomes, which is made more challenging by the varieties of diversity facing us. Diversity is not just an issue related to student recruitment or experience, but rather it is one that also relates to institutions and their faculties. New educational methods must address such diversity to be effective, and one possible example can be found in ongoing research at the University of Michigan that explores the educational implications of implementing a web-based lecture capture system in large lecture courses. Student use of and reactions to such systems is important, as is the potential to influence course performance for students in general, but also for underrepresented and at-risk student subpopulations. In addition to helping bring our current landscape into focus, this paper will identify effective practices as well as continuing challenges to improving educational practice for undergraduate students.

The transition of IMGs into the health care system in the UK is accompanied by significant sociocultural and educational challenges. This study aims to explore the views of IMGs in medical training on the educational challenges they face.Methods: This study was conducted in the Kent, Surrey and Sussex region in 2015. All IMGs who work in medical (physicianly training programs were included. Data were collected through a questionnaire and semi-structured interviews. Thematic approach was used to analyze the qualitative data.Results: Of the total 61 IMGs included, 17 responded to the survey and 3 were interviewed. The common educational barriers faced by IMGs were related to lack of appreciation of the values and structure of the National Health Service (NHS, ethical and medicolegal issues, receiving feedback from colleagues and the different learning strategies in the UK. IMGs suggested introduction of a mandatory dedicated induction program in the form of formal teaching sessions. They also believed that a supervised shadowing period prior in the first job in the UK would be beneficial. Further assessment areas should be incorporated into the prequalifying examinations to address specific educational needs such as NHS structure and hospital policies. Other measures such as buddying schemes with senior IMGs and educating NHS staff on different needs of IMGs should also be considered.Conclusion: This study highlighted important educational challenges faced by IMGs and generated relevant solutions. However, the opinions of the supervisors and other health care professionals need to be explored. Keywords: international medical graduates, IMG, educational barriers

  5. Mentoring during residency education: a unique challenge for the surgeon?

    Science.gov (United States)

    Pellegrini, Vincent D

    2006-08-01

    A mentor serves as role model, counselor, and advocate for an understudy or protégé. The art and science of mentoring have been investigated most thoroughly in the educational literature, yet there are unique situational and individual considerations in the surgical arena that may warrant special consideration. The general attributes of successful mentors are not foreign to academic surgeons but may require deliberate cultivation to optimize mentorship in the context of academic medicine. Moreover, the stages of productive mentoring may be counter to the learned adaptive behaviors and instinctive personality traits of some accomplished surgeon educators. Indeed, examples of failed mentorship are common in our medical centers and, specifically, in surgical training programs. The behavioral adaptation that supports surgical decision-making under conditions of incomplete data and unusual stress often devalues succession planning and derivation of satisfaction from the success of other members of the team. Accordingly, fostering effective mentoring relationships in academic surgery will require a concerted effort to develop appropriate behaviors conducive to the mentoring process. The personal and professional growth of our students as well as the succession planning for our specialty are dependent upon the successful creation of an environment conducive to mentoring in academic orthopaedics.

    Ross, Lars A; Olson, Ingrid R

    2012-09-01

    Famous people and artifacts are referred to as "unique entities" (UEs) due to the unique nature of the knowledge we have about them. Past imaging and lesion experiments have indicated that the anterior temporal lobes (ATLs) as having a special role in the processing of UEs. It has remained unclear which attributes of UEs were responsible for the observed effects in imaging experiments. In this study, we investigated what factors of UEs influence brain activity. In a training paradigm, we systematically varied the uniqueness of semantic associations, the presence/absence of a proper name, and the number of semantic associations to determine factors modulating activity in regions subserving the processing of UEs. We found that a conjunction of unique semantic information and proper names modulated activity within a section of the left ATL. Overall, the processing of UEs involved a wider left-hemispheric cortical network. Within these regions, brain activity was significantly affected by the unique semantic attributes especially in the presence of a proper name, but we could not find evidence for an effect of the number of semantic associations. Findings are discussed in regard to current models of ATL function, the neurophysiology of semantics, and social cognitive processing.

  7. Breast cancer: unique communication challenges and strategies to address them.

    Parker, Patricia A; Aaron, Joann; Baile, Walter F

    2009-01-01

    Women with breast cancer have become increasingly more involved on a national and local level in advocating for resources to fight cancer. However, in the context of the relationship with their physicians and other cancer caregivers, much remains to be done in providing them with adequate support. In this paper, we highlight the difficulties in communication related to breast cancer and describe strategies and approaches that may be helpful in improving the communication throughout the cancer trajectory. Specifically, breast cancer patients have high unmet information needs relevant to health information and dissatisfaction with the actual information they receive from their providers. These needs seem even more pronounced when patients are older, of lower socio-economic class and from differing cultural backgrounds which may affect their ability to express their desires for information and desire to be involved in decision-making about their treatment. Other communication challenges can be envisioned as occurring at key points across the cancer trajectory: diagnosis disclosure, treatment failure, transition to palliative care, and end of life discussions. These involve techniques as basic as how to establish trust and rapport and determine a patient's information and decision-making preferences and as complex as giving bad news. These strategies are now viewed as essential skills in that they can affect patient distress and quality of life, satisfaction, and malpractice litigation as well as practitioner stress and burnout.

  8. The Challenges Faced by New Science Teachers in Saudi Arabia

    Science.gov (United States)

    Alsharari, Salman

    Growing demand for science teachers in the Kingdom of Saudi Arabia, fed by increasing numbers of public school students, is forcing the Saudi government to attract, recruit and retain well-qualified science teachers. Beginning science teachers enter the educational profession with a massive fullfilment and satisfaction in their roles and positions as teachers to educating children in a science classroom. Nevertheless, teachers, over their early years of practice, encounter numerous challenges to provide the most effective science instruction. Therefore, the current study was aimed to identify academic and behavioral classroom challenges faced by science teachers in their first three years of teaching in the Kingdom of Saudi Arabia. In addition, new science teacher gender, school level and years of teaching experience differences in perceptions of the challenges that they encountered at work were analyzed. The present study also investigated various types of support that new science teachers may need to overcome academic and behavioral classroom challenges. In order to gain insights about ways to adequately support novice science teachers, it was important to examine new science teachers' beliefs, ideas and perceptions about effective science teaching. Three survey questionnaires were developed and distributed to teachers of both sexes who have been teaching science subjects, for less than three years, to elementary, middle and high school students in Al Jouf public schools. A total of 49 novice science teachers responded to the survey and 9 of them agreed to participate voluntarily in a face-to-face interview. Different statistical procedures and multiple qualitative methodologies were used to analyze the collected data. Findings suggested that the top three academic challenges faced by new science teachers were: poor quality of teacher preparation programs, absence of appropriate school equipment and facilities and lack of classroom materials and instructional

  9. Unique Challenges for Modeling Defect Dynamics in Concentrated Solid-Solution Alloys

    Science.gov (United States)

    Zhao, Shijun; Weber, William J.; Zhang, Yanwen

    2017-07-01

    Recently developed concentrated solid solution alloys (CSAs) are shown to have improved performance under irradiation that depends strongly on the number of alloying elements, alloying species, and their concentrations. In contrast to conventional dilute alloys, CSAs are composed of multiple principal elements situated randomly in a simple crystalline lattice. As a result, the intrinsic disorder has a profound influence on energy dissipation pathways and defect evolution when these CSAs are subjected to energetic particle irradiation. Extraordinary irradiation resistance, including suppression of void formation by two orders of magnitude at an elevated temperature, has been achieved with increasing compositional complexity in CSAs. Unfortunately, the loss of translational invariance associated with the intrinsic chemical disorder poses great challenges to theoretical modeling at the electronic and atomic levels. Based on recent computer simulation results for a set of novel Ni-containing, face-centered cubic CSAs, we review theoretical modeling progress in handling disorder in CSAs and underscore the impact of disorder on defect dynamics. We emphasize in particular the unique challenges associated with the description of defect dynamics in CSAs.

    2015-09-21

    Strong economic development in China has led to a surge in status consumption as a means of gaining face. In Eastern culture, people interpret uniqueness as status distinction rather than separateness or deviance. This type of uniqueness can be used to meet others' expectations and gain social approval. Thus its relationship with face consciousness and status consumption is to be expected. This study investigates 2 hypotheses: (a) Face consciousness has a positive effect on status consumption and (b) Consumer need for uniqueness mediates the relationship between face consciousness and status consumption. Two-hundred and forty-six working respondents in eastern China completed a survey. Regression analysis of the results supported both hypotheses.

    This study examines challenges faced by refugee new parents from Africa in Canada. Refugee new parents from Zimbabwe (n = 36) and Sudan (n = 36) were interviewed individually about challenges of coping concurrently with migration and new parenthood and completed loneliness and trauma/stress measures. Four group interviews with refugee new parents (n = 30) were subsequently conducted. Participants reported isolation, loneliness, and stress linked to migration and new parenthood. New gender roles evoked marital discord. Barriers to health-related services included language. Compounding challenges included discrimination, time restrictions for financial support, prolonged immigration and family reunification processes, uncoordinated government services, and culturally insensitive policies. The results reinforce the need for research on influences of refugees' stressful experiences on parenting and potential role of social support in mitigating effects of stress among refugee new parents. Language services should be integrated within health systems to facilitate provision of information, affirmation, and emotional support to refugee new parents. Our study reinforces the need for culturally appropriate services that mobilize and sustain support in health and health related (e.g., education, employment, immigration) policies.

    2005-12-01

    One of the main tasks of a problem-based learning (PBL) tutor is to facilitate group discussion. Group facilitation is about process rather than content. In this process, a tutor helps the group increase their skills and progress in their discussion. Several studies have highlighted strategies and training used in preparing PBL tutors. However, PBL tutors usually feel that it is not that easy to change their teaching style to the PBL format.

    Full Text Available This article focuses on one of the main challenges that Central Asian armies face, that is, the problem of training and formation. Having rapidly increased since 2007, Central Asian military budgets have been able to multiply the purchases of equipment and weapons from foreign partners (Russia, western countries, Israel, China, South Korea, etc.. Money is not enough, however, to get the military institution back on its feet in its most human aspect, that of formation. In fact, the teaching institutions and the training possibilities provided to conscripts and professional soldiers on contract are generally of inadequate quality and impede the overall military capacities of the Central Asian states. This article will examine the main problems of the Central Asian military institutions and will discuss the means that have been implemented by Central Asian governments to reduce the negative impact of difficulties in promoting human capital.

    2015-07-01

    Craniofacial anomalies are among the most common human birth defects and have considerable functional, aesthetic, and social consequences. The early developmental origin as well as the anatomical complexity of the head and face render these tissues prone to genetic and environmental insult. The establishment of craniofacial clinics offering comprehensive care for craniofacial patients at a single site together with international research networks focused on the origins and treatment of craniofacial disorders has led to tremendous advances in our understanding of the etiology and pathogenesis of congenital craniofacial anomalies. However, the genetic, environmental, and developmental sources of many craniofacial disorders remain unknown. To overcome this problem and further advance craniofacial research, we must recognize current challenges in the field and establish priority areas for study. We still need (i) a deeper understanding of variation during normal development and within the context of any disorder, (ii) improved genotyping and phenotyping and understanding of the impact of epigenetics, (iii) continued development of animal models and functional analyses of genes and variants, and (iv) integration of patient derived cells and tissues together with 3D printing and quantitative assessment of surgical outcomes for improved practice. Only with fundamental advances in each of these areas will we be able to meet the challenge of translating potential therapeutic and preventative approaches into clinical solutions and reduce the financial and emotional burden of craniofacial anomalies.

    Full Text Available At present face recognition has wide area of applications such as security, law enforcement. Imaging conditions, Orientation, Pose and presence of occlusion are huge problems associated with face recognition. The performance of face recognition systems decreases due to these problems. Discriminant Analysis (LDA or Principal Components Analysis (PCA is used to get better recognition results. Human face contains relevant information that can extracted from face model developed by PCA technique. Principal Components Analysis method uses eigenface approach to describe face image variation. A face recognition technique that is robust to all situations is not available. Some techniques are better in case of illumination, some for pose problem and some for occlusion problem. This paper presents some algorithms for face recognition.

    2009-12-15

    This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems. (author)

  1. Challenges facing academic urology training programs: an impending crisis.

    Gonzalez, Chris M; McKenna, Patrick

    2013-03-01

    To determine the most pressing issues facing academic urology training centers. The supply of urologists per capita in the United States continues to decrease. Stricter resident requirements, restriction of resident duty hours, and a Graduate Medical Education (GME) funding cap on resident education has led to significant challenges for academic centers. A 32-question survey was sent to Society of University Urologists members. Respondents defined themselves as academic faculty tenure track, program director, academic chair, program director and academic chair, clinical faculty nontenure track, and community faculty member. A total of 143 of 446 members(32%) responded. A lack of funding was indicated as an obstacle to adding new residency positions (65% respondents) and recruiting new faculty (60% respondents). Residency positions not funded by GME (40% respondents) required either clinical or hospital dollars to support these slots. Most respondents (51%) indicated resident research rotations are funded with clinical dollars. Surgical skills laboratories are commonly used (85% respondents) and are supported mostly with hospital or clinical dollars. The majority of respondents (84%) indicated they would expand simulation laboratories if they had better funding. Other than urodynamics and ultrasound, urology residency training programs reported little income from ancillary dollars. There is a significant workforce shortage within urology training programs. Clinical revenue and hospital funding seem to be the main financial support engines to supplement the GME funding shortage, proficiency training, and faculty salary support for teaching. The current system of GME funding for urology residency programs is not sustainable. Published by Elsevier Inc.

    The U.S. Department of Energy (DOE) and the U.S. automotive industry are working cooperatively under the auspices of the Partnership for a New Generation of Vehicles (PNGV) to develop a six-passenger automobile that can achieve up to 80 mpg. while meeting customer needs and all safety and emission requirements. These partners are continuing to invest heavily in the research and development of polymer electrolyte membrane (PEM) fuel cells as a clean and efficient energy conversion system for the PNGV. A critical challenge facing fuel cell systems for the PNGV is the development of efficient, compact, cost-effective air management systems. The U.S. Department of Energy has been exploring several compressor/expander options for pressurized fuel cell systems, including scroll, toroidal intersecting vane, turbine, twin screw, and piston technologies. Each of these technologies has strengths and weaknesses regarding efficiency, pressure ratio over turndown, size and weight, and cost. This paper will present data from the U.S. Department of Energy's research and development efforts on air management systems and will discusses recent program developments resulting from an independent peer review evaluation.

    2006-12-01

    The Alaska Satellite Facility (ASF) of the Geophysical Institute, University of Alaska Fairbanks, has just celebrated its 15th year of experience in satellite remote sensing. ASF is involved in a wide range of activities - - from downlinking satellite data to developing data analysis tools, value-added products, and training for Synthetic Aperture Radar (SAR) users. Satellite remote sensing data are acquired, processed, analyzed, and archived by ASF from several satellites; ASF has built expertise in handling and manipulating the data, SAR in particular. SAR is the only satellite imagery in the world today that can be acquired at any time of the day or night and during adverse weather conditions. It can be used to develop value-added products to aid in global climate change research. Examples include the SAR-derived coastal winds in the Gulf of Alaska and Bering Sea; monitoring of the major ice shelves in the Arctic and Antarctic; and examining the impact on sea level from the Greenland ice sheets and glaciers. The challenges facing the use of remote-sensing data in climate change research can be divided into three major categories: economical, political, and technical. The expense of designing, building, and launching a satellite is substantial. The costs of the ground segment including data management can be substantial and should not be neglected. The US agency funding climate often has the research community pushing for new missions against declining federal budgets in direct competition with ongoing missions. On the political front, data policy, data ownership, and cost recovery are issues often perceived as insurmountable by the user community. The technical issues, while challenging, are often the easiest to solve. The Japan Aerospace Exploration Agency, with the successful launch of the Advanced Land Observing System (ALOS), has embarked on a new way of handling the ground segment with the introduction of international data nodes. ASF will serve with NOAA

  4. A personal perspective on challenges that face women scientists

    2016-04-01

    Gender equality has been a topic of discussion throughout my long (now three decade) career. This alone illustrates the complex nature of the issue, and the lack of a simple solution, particularly as many of the daily challenges that women face are institution or discipline-specific. For this reason, I will summarize some of the issues that appear to me to be more general, and therefore ones that may have general solutions. The first and foremost relates to demands on women's time. One way that academic institutions have sought to overcome gender bias has been to require that every university committee have a female member; in departments, schools and faculties where women represent a minority, this necessarily means that women shoulder an inequitable share of the service duties. I have experienced this myself, seen it in promotion files at all levels, and observed it with regard to my female colleagues. Clearly time spent doing service is time not spent doing science. There is also an easy solution to this problem, which is to re-think the underlying assumption that men are necessarily gender-biased if they don't have a woman sitting in the room! Additional time demands can come from informal mentoring of both students and younger colleagues, particularly in cases where senior male colleagues are viewed as too important, or too intimidating, to be consulted on personal issues. Although I suspect that this problem may also be widespread, it is more difficult to quantify, and is therefore more difficult to factor into time allotments of departmental duties. A final thought relates to hiring practices. I have now worked in both the US and UK educational systems, which have very different interview and hiring protocols. I will review both, highlighting components that I think are most likely to promote equitable hiring practices.

    Sigall (1997) asserted that the bogus pipeline (BPL) methodology is not a uniquely deceptive technique and, therefore, does not pose unique ethical challenges for social psychology researchers. We argue that empirical research is needed to clarify the controversial issue of the ethics of using the BPL. Results of such a research program will provide guidance for researchers as well as institutional review boards regarding conditions under which the use of the BPL may or may not be ethically justified.

    Campbell, Karen M

    2013-01-01

    The purpose of this case report was to describe oral findings and outline challenges and considerations for general anesthetic (GA) and dental management of 4-year-old female craniopagus (cranially conjoined) twins, at high risk for medical comorbidity, who presented for treatment of severe early childhood caries. This hospital-based procedure required good interdisciplinary communication, cooperation, and presurgical planning to address unique challenges and ensure positive postoperative outcomes. Two separate anesthesia teams delivered GA simultaneously to each twin. To minimize anesthetic exposure, two pediatric dental teams completed dental care concurrently. Extensive plaque accumulation and unusual "mirror-image" caries distribution were attributed to frequency and postural pooling during feeding. The rehabilitation objective was to provide definitive dental management, minimizing future need for dental retreatment under GA. Two-month follow-up revealed intact dental restorations, good oral hygiene, and weight gain. For these unique twins however, the challenge of long-term oral health maintenance remains.

  9. Tolerance for distorted faces: challenges to a configural processing account of familiar face recognition.

    Science.gov (United States)

    Sandford, Adam; Burton, A Mike

    2014-09-01

    Face recognition is widely held to rely on 'configural processing', an analysis of spatial relations between facial features. We present three experiments in which viewers were shown distorted faces, and asked to resize these to their correct shape. Based on configural theories appealing to metric distances between features, we reason that this should be an easier task for familiar than unfamiliar faces (whose subtle arrangements of features are unknown). In fact, participants were inaccurate at this task, making between 8% and 13% errors across experiments. Importantly, we observed no advantage for familiar faces: in one experiment participants were more accurate with unfamiliars, and in two experiments there was no difference. These findings were not due to general task difficulty - participants were able to resize blocks of colour to target shapes (squares) more accurately. We also found an advantage of familiarity for resizing other stimuli (brand logos). If configural processing does underlie face recognition, these results place constraints on the definition of 'configural'. Alternatively, familiar face recognition might rely on more complex criteria - based on tolerance to within-person variation rather than highly specific measurement.

    Biofield therapies (BTs) are increasingly employed in contemporary healthcare. In this white paper, we review specific challenges faced by biofield practitioners resulting from a lack of (1) a common scientific definition of BT; (2) common educational standards for BT training (including core competencies for clinical care); (3) collaborative team care education in complementary and alternative medicine (CAM) and in integrative health and medicine (IHM); (4) a focused agenda in BT research; and (5) standardized devices and scientifically validated mechanisms in biofield research. We present a description of BT and discuss its current status and challenges as an integrative healthcare discipline. To address the challenges cited and to enhance collaboration across disciplines, we propose (1) standardized biofield education that leads to professional licensure and (2) interprofessional education (IPE) competencies in BT training required for licensed healthcare practitioners and encouraged for other practitioners using these therapies. Lastly, we discuss opportunities for growth and a potential strategic agenda to achieve these goals. The Academy of Integrative Health and Medicine (AIHM) provides a unique forum to facilitate development of this emerging discipline, to facilitate IPE, and to further increase the availability of BT to patients.

    The future information systems are expected to be more intelligent and will take human queries in natural language as input and answer them promptly. To develop a chatbot or a computer program that can chat with humans in realistic manner to extent that human get impressions that he/she is talking with other human is a challenging task. To make such chatbots, different technologies will work together ranging from artificial intelligence to development of semantic resources. Sophisticated chatbots are developed to perform conversation in number of languages. Arabic chatbots can be helpful in automating many operations and serve people who only know Arabic language. However, the technology for Arabic language is still in its infancy stage due to some challenges surrounding the Arabic language. This paper offers an overview of the chatbot application and the several obstacles and challenges that need to be resolved to develop an effective Arabic chatbot.

    2016-01-01

    Full Text Available Political leadership is a concept central to understanding political processes and outcomes, yet its definition is elusive. The study of political leadership has a long history. Many disciplines have contributed to this study, including history, philosophy, political theory, psychology etc. Leadership is a process in which leaders and followers interact dynamically in a particular situation or context. Leaders must be able to connect with followers to understand their mood and their initiative. There are essential and operational differences between a leader and a manager. Managerial effectiveness is related to an emphasis on rationality and organizational structure. Leadership effectiveness is linked to symbols and culture. The interactive nature of leader-followers-situation can help us better understand the changing nature of the leaderfollower relationship and the increasingly greater complexity of situations leaders and followers face in contemporary world. Good leadership makes a difference, and it can be enhanced through greater awareness of the important factors influencing the leadership process. The changes we are facing in today’s world demand a new breed of political leaders, new forms and mechanisms of leader-follower interaction that provide effective leadership. 

  6. From Toques to Tokes: Two challenges facing nationwide legalization of cannabis in Canada.

    Science.gov (United States)

    Bear, Daniel

    2017-04-01

    In 2015, a new Liberal Government came to power in Canada, elected on a platform that included legalization and regulation of cannabis for recreational purposes. Their legislation, based on recommendations from a Federal Task Force on Marijuana Legalization and Regulation, is due in early April 2017. This commentary utilizes Canadian Federal policy papers, previous literature, and internal and international agreements to examine two key areas critical to the development of a nationwide regulated market for cannabis in Canada; the need to overcome restrictions to legalizing cannabis in United Nations' drug control treaties, and the unique challenges that non-medical cannabis creates for navigating interprovincial trade policies in Canada. Irrespective of UN conventions that appear to prohibit legalization of cannabis the Government is preparing to bring forward legislation as this article goes to print. At the same time significant squabbles impede the selling of even beer and wine inter-provincially in Canada. This paper identifies the challenges facing Canadian legalization efforts, but also shows how the legalization legislation may provide opportunities to engender significant change beyond the simple legalization of a specific drug. This commentary does not argue for any specific course of action for Canada, but rather explores the nuance of legalization absent from the declaration in the Liberal party platform. The paper argues that Canada's efforts may hasten the dismantling of the UN drug control structure, and provide renewed opportunities for intern-provincial trade in Canada.

Scarcity of organs for transplantation necessitates formulation of just and fair allocation policies as well as ethically viable solutions to bridging the vast gap between organ supply and demand. The concept of "triage" provides a useful paradigm in which to contextualize the organ shortage issue. This entails subjugating the welfare of the individual patient for the benefit of the wider community as an ethically justified response to the challenge of scarcity.

    The United States Food and Drug Administration (FDA) has proposed creating a unique device identification (UDI) system for medical devices to facilitate postmarket surveillance, quality improvement, and other applications. Although a small number of health care institutions have implemented initiatives comparable with the proposed UDI system by capturing data in electronic health record (EHR) systems, it is unknown whether institutions with fewer resources will be able to similarly implement UDI. This paper calls attention to organizational, workflow, and technological challenges in UDI system implementation by drawing from the literature on EHR and clinical research systems implementation. Organizational challenges for UDI system implementation include coordinating multiple stakeholders to define UDI attributes and characteristics for use in EHRs, guiding organizational change within individual institutions for integrating UDI with EHRs, and guiding organizational change for reusing UDI data captured in EHRs. Workflow challenges include capturing UDI data in EHRs using keyboard entry and barcode scanning. Technological challenges involve interfacing UDI data between EHRs and surgical information systems, transforming UDI and related patient data from EHRs for research, and applying data standards to UDI within and beyond EHRs. We provide recommendations for regulations, organizational sharing, and professional society engagement to raise awareness of and overcome UDI system implementation challenges. Implementation of the UDI system will require integration of people, process, and technology to achieve benefits envisioned by FDA, including improved postmarket device surveillance and quality of care.

    Full Text Available BACKGROUND: Clinical teaching is an important component of clinical education. In nursing, clinical teaching is ensured by clinical nurse educators (CNEs. This study aimed at describing the major challenges faced by CNEs in Cameroon. METHODS: In a qualitative study, supplemented with quantitative methods, CNEs were enrolled from three health districts to represent their frequency in Cameroon’s health delivery system. RESULTS: A total of 56 CNEs participated in the study, of whom, as many as 58.9% acknowledged always facing challenges in clinical teaching and supervision. The major challenges identified were the lack of opportunities to update knowledge and skills, students’ lack of preparedness and the CNEs not being prepared for clinical teaching. CNEs attributed these challenges in major part to the lack of incentives and poor health policies. CONCLUSION: CNEs in Cameroon do indeed face major challenges which are of diverse origins and could adversely affect teaching in clinical settings

    Full Text Available The project of the European construction has been subject to constant contradictions since the time of its first steps of implementation. Beyond the ideal of economic and political unification, the European Union has to manage more and more cultural, social, and economic challenges, which aren’t at all negligible, and all the more pressing in the context of recent years marked by the global financial crisis and the assault of asylum seekers from Africa and Middle East. Therefore we can launch a series of interrogations: What is the citizens’ level of trust in the European construction project? How does the European Union proceed in order to integrate immigrants? What is the link between good immigrant integration and consolidation of the European construction project? These three interrogations represent the axes of analysis of this article, which aims to highlight some theoretical aspects of the effects of current migration on the structuring or restructuration of the European Union. As a conclusion, we may say that the current challenges of migration have opened the path to a new phase of the European construction project, and the consensus of state actors and the direct involvement of the Community institutions can be decisive in shaping the medium and long term evolution of the European Union.

    Full Text Available Problem statement: The nature of sustainable development requires new paradigms for education. Issues of sustainability are ‘wicked problems’ that do not lend themselves to conventional didactic approaches. The challenge for higher education is to examine interdisciplinary approaches to global societal responsibility and, within this, issues of education for sustainable development. Approach: A project, sponsored by the Royal Academy of Engineering, developed a course unit in sustainable development across several disciplines. The approach was initially pedagogic in nature, with a strong evaluative theme. At the same time, a Delphi study was undertaken by the same team and this inter-relates with the main project. The focus of the action research was a series of ‘wicked’ problems that would provide real-world challenges with no simple answers. Results: The project was evaluated in a number of ways, not least the pre-and post-testing of students’ attitudes and approaches, but also using nominal group techniques. The project demonstrated that an interdisciplinary PBL approach succeeded in deepening the learning of the students as well as developing key skills. Conclusion: The use of collaborative, group-based approaches, notably PBL, offers a key way of approaching the design of curricula for sustainable development and other areas of global societal responsibility that hinge on ‘wicked problems’.

    Bernat, James L

    2014-09-30

    Challenges to ethics and professionalism that can harm neurologists and their patients include the commercialization of medicine, poorly designed Medicare regulations, conflicts of interest, physician employment by hospitals, faulty measurement of medical quality care, electronic health records, electronic communications with patients, and the demotion of the role of physician beneficence. These threats can lead to inaccurate medical record-keeping, unnecessary medical care, a decline in the primacy of patients' interests, and damage to the sanctity of the patient-physician relationship. The increasing frequency of physician burnout can be attributed at least partially to unmitigated stresses on practicing physicians, particularly the growing time pressures for patient visits, the mounting daily requirements of documentation, and the increasing burden of time-consuming but unproductive tasks. Recommended correctives include reforming billing documentation regulations, improving electronic health records, designing proper quality indicators integrating physician wellness, and incorporating reasonable physician workflows in the design of accountable care organizations.

    2015-01-01

    The Solar Updraft Power Plant technology addresses a very challenging idea of combining two kinds of renewable energy: wind and solar. The working principle is simple: a Solar Updraft Power Plant (SUPP) consists of a collector area to heat the air due to the wide-banded ultra-violet solar radiation, the high-rise solar tower to updraft the heated air to the atmosphere, and in between the power conversion unit, where a system of coupled turbines and generators transforms the stream of heated air into electric power. A good efficiency of the power plant can only be reached with extra-large dimensions of the tower and/or the collector area. The paper presents an up-to-date review of the SUPP technology, focusing on the multi-physics modeling of the power plant, on the structural behavior of the tower and, last but not least, on the modeling of the stochastic wind loading process.

It aims to motivate research and its funding regarding digital threats and vulnerabilities related, in particular, to anticipating unintended, undesirable rebound effects, tipping points, critically fast evolutionary change rates, trade-offs, etc. A brief analysis of the history of the mind and technology reveals slow technological development over tens of thousands of years (including the invention of a place-value digital number system. Then, a small series of groundbreaking ideas (e.g., binary logic, Shannon’s symbolic analysis of relay and switching circuits, architectures of computing enabled the industry-driven invention of programmable computing machines. Ultimately, the mastery of electron and semiconductor physics allowed for economical and seemingly unlimited storage capacity that made digital tools available to all domains of society. Based on the historical analysis, a coupled human-environment systems perspective (that includes a hierarchy assumption ranging from the human cell to the human species enables the identification of several potential challenges to society and science. First, digital nano-engineering promotes genetic modifications (i.e., directed evolution, and synthetic biology enables a new level of the appropriation of nature. The understanding of cell-based biocomputers may call for new forms of logic. These and other challenges require thorough sustainability research in order to anticipate major changes on all levels of human systems. Second, the human individual is exposed to new forms of vulnerability. In particular, the potential epigenetic effects resulting from the excessive use of digital information of historically unknown speed, density, and contents and the loss of (the Western common-law right to privacy resulting from big data (whose ownership is often unknown should become subjects of

    The human resources crisis in humanitarian health care parallels that seen in the broader area of health care. This crisis is exacerbated by the lack of resources in areas in which humanitarian action is needed--difficult environments that often are remote and insecure--and the requirement of specific skill sets is not routinely gained during traditional medical training. While there is ample data to suggest that health outcomes improve when worker density is increased, this remains an area of critical under-investment in humanitarian health care. In addition to under-investment, other factors limit the availability of human resources for health (HRH) in humanitarian work including: (1) over-reliance on degrees as surrogates for specific competencies; (2) under-development and under-utilization of national staff and beneficiaries as humanitarian health workers; (3) lack of standardized training modules to ensure adequate preparation for work in complex emergencies; (4) and the draining of limited available HRH from countries with low prevalence and high need to wealthier, developed nations also facing HRH shortages. A working group of humanitarian health experts from implementing agencies, United Nations agencies, private and governmental financiers, and members of academia gathered at Hanover, New Hampshire for a conference to discuss elements of the HRH problem in humanitarian health care and how to solve them. Several key elements of successful solutions were highlighted, including: (1) the need to develop a set of standards of what would constitute "adequate training" for humanitarian health work; (2) increasing the utilization and professional development of national staff; (3) "training with a purpose" specific to humanitarian health work (not simply relying on professional degrees as surrogates); (4) and developing specific health task-based competencies thereby increasing the pool of potential workers. Such steps would accomplish several key goals, such as

    Full Text Available The search for electroceramic materials with enhanced ferro-pyro-piezoelectric properties and revealing the perovskite type structure has been the objective of a significant number of manuscripts reported in the literature. This has been usually carried out by proposing the synthesis and processing of new compounds and solid solution series. In this work, several methods to obtain ferro-pyro-piezoelectric families of materials featuring the well-known ABO3 perovskite structure (or related such as BaTiO3, Ba1–xCaxTi1–yZryO3, (Bi0.5Na0.5TiO3, (K0.5Na0.5NbO3 and their solid solutions with different cations either in the A or B positions, are presented. For this kind of materials, the challenge for obtaining a single phase compound with a specific grain size and morphology and, most importantly, with the adequate stoichiometry, will also be discussed. The results reviewed herein will be discussed in terms of the tendency of working with softer conditions, i.e., lower temperature and shorter reaction times, also referred to as soft-chemistry.

Abnormal anxiety levels are found in up to 40% of patients with IBD. Anxiety symptoms are often related to flares of IBD but may persist in times of remission. Detection of anxiety disorder (AD in patients with IBD can be challenging. Patients with anxiety may also exhibit symptoms in keeping with functional gastrointestinal disorders (FGID. Evidence for the effectiveness of pharmacological and psychological therapies for anxiety stems from patients without IBD. Studies in patients with IBD have either been small or shown negative results. In light of this, a combined approach involving IBD physicians to improve disease control and psychologists or psychiatrists to treat anxiety is advised. This review examines the evidence of anxiety issues in IBD with a focus on extent of the problem, risk factors for anxiety, and the effectiveness of interventions.

    Full Text Available One of the challenges of teaching pre-teens about the internet is their varying degrees and levels of involvement. The juvenile police officer brings a solid understanding of the laws as well as a strong knowledge of safety issues to the classroom, making them an excellent educational resource. Officers can utilize an educational approach with parents and students in which they define what cyber bullying is and, importantly, demonstrate that definition by describing real cases that I and other officers have addressed. This approach focused both on the effect that cyber bullying has on the victims and the impact of the online behavior on the atmosphere and climate at the school. Students and parents also need to learn about the potential consequences for the perpetrator. Finally, an important method for bridging varying degrees of involvement in bullying is to emphasize that all students play a role in cyber bullying prevention-not merely those who perpetrate it or are victimized by it. That lesson is accomplished through discussions about strategies that bystanders can use to intervene."

  6. Representative Delay Measurements (RDM: Facing the Challenge of Modern Networks

    2015-02-01

    Full Text Available Network access technologies have evolved significantly in the last years. They deploy novel mechanisms like reactive capacity allocation and time-slotted operation to optimize overall network capacity. From a single node's perspective, such optimizations decrease network determinism and measurement repeatability. Evolving application fields like machine to machine (M2M communications or real-time gaming often have strict real-time requirements to operate correctly. Highly accurate delay measurements are necessary to monitor network compliance with application demands or to detect deviations of normal network behavior, which may be caused by network failures, misconfigurations or attacks. This paper analyzes factors that challenge active delay measurements in modern networks. It introduces the Representative Delay Measurement tool (RDM that addresses these factors and proposes solutions that conform to requirements of the recently published RFC7312. Delay measurement results acquired using RDM in live networks confirm that advanced measurement methods can significantly improve the quality of measurement samples by isolating systematic network behavior. The resulting high-quality samples are one prerequisite for accurate statistics that support proper operation of subsequent algorithms and applications.

It is coauthored by academic researchers and senior service providers so as to embrace the multidimensional issues impacting on this subject. If lean thinking is to be implemented in relation to health visiting, it is important to understand how it is likely to be viewed by practitioners and line managers in settings where it is used. In order to contextualize the discussion, an introduction to the roles, systems, and structures of health visiting are provided. The literature on what lean implementation is, what it means, and in particular the application and potential of the approach to primary care and public health services is reviewed. The process and findings from a focus group convened within a large primary care organization in the National Health Service during their lean implementation is reported. The paper concludes that it is important for staff at all levels to see a clear link between strategic aims and objectives and the planning processes operated by providers and commissioners. It appears that the successful introduction of lean thinking should focus more on productive working and thereby reducing waste. This has the potential to refresh workforce models to ensure that health visiting and other practitioners liberate the use of their specialist knowledge and skills. In a context of enhanced partnership working, the stage is then set for providers to add value to the whole

    2014-05-01

    This paper demonstrates the importance of proper model specification when analyzing time-series count data in political communication studies. It is common for scholars of media and politics to investigate counts of coverage of an issue as it evolves over time. Many scholars rightly consider the issues of time dependence and dynamic causality to be the most important when crafting a model. However, to ignore the count features of the outcome variable overlooks an important feature of the data. This is particularly the case when modeling data with a low number of counts. In this paper, we argue that the Poisson autoregressive model (Brandt and Williams, 2001) accurately meets the needs of many media studies. We replicate the analyses of Flemming et al. (1997), Peake and Eshbaugh-Soha (2008), and Ura (2009) and demonstrate that models missing some of the assumptions of the Poisson autoregressive model often yield invalid inferences. We also demonstrate that the effect of any of these models can be illustrated dynamically with estimates of uncertainty through a simulation procedure. The paper concludes with implications of these findings for the practical researcher.

    Along the nearly 3,200 kilometers (almost 2,000 miles) of the United States–Mexican border, in an area known as the Borderlands, we are witnessing the expression of the challenges of the 21st century. This circular identifies several challenge themes and issues associated with life and the environment in the Borderlands, listed below. The challenges are not one-sided; they do not originate in one country only to become problems for the other. The issues and concerns of each challenge theme flow in both directions across the border, and both nations feel their effects throughout the Borderlands and beyond. The clear message is that our two nations, the United States and Mexico, face the issues in these challenge themes together, and the U.S. Geological Survey (USGS) understands it must work with its counterparts, partners, and customers in both countries.Though the mission of the USGS is not to serve as land manager, law enforcer, or code regulator, its innovation and creativity and the scientific and technical depth of its capabilities can be directly applied to monitoring the conditions of the landscape. The ability of USGS scientists to critically analyze the monitored data in search of signals and trends, whether they lead to negative or positive results, allows us to reach significant conclusions—from providing factual conclusions to decisionmakers, to estimating how much of a natural resource exists in a particular locale, to predicting how a natural hazard phenomenon will unfold, to forecasting on a scale from hours to millennia how ecosystems will behave.None of these challenge themes can be addressed strictly by one or two science disciplines; all require well-integrated, cross-discipline thinking, data collection, and analyses. The multidisciplinary science themes that have become the focus of the USGS mission parallel the major challenges in the border region between Mexico and the United States.

    competitiveness, measured in terms of scientific yield and citations, primarily affects fields where articles and citations are not the traditional outputs, such as the humanities and social sciences in general and planning-related disciplines in particular. When discussing planning, it has to be stressed out that research has a merely societal value and is not aimed at developing products that can foster economic growth or delivering scientific articles that profoundly change the theoretical perspectives. Simply put, research in planning aims at increasing the safety and welfare of people. As a consequence, planning research topics have shifted from providing scientific grounds to regional development policies, to addressing research quality and social responsibility or producing research guidelines. This article looks at the particular case of Romanian planning research based on SCImago data, in an attempt to assess whether this field is able to meet these global challenges, especially after the consistent, albeit uneven, in terms of goal and pace, application of new research policies designed after joining the European Union, which were aimed at increasing its article output and its international visibility. The findings indicate that the numerical growth of articles and publications is spectacular in Romania for most fields, and even more so within the humanities, the social sciences and planning. However, the question remains whether this impressive growth is supported by an increase in quality. We have therefore left aside matters such as the globalization of authors, topics or citations. These aspects require a more in-depth research effort.

    Clark, David J.; Dakin, Brian V. [Amec Oil and Gas Americas, Houston, TX (United States)

    2012-07-01

    In early 2010, PETROBRAS accepted bids for the design, fabrication, installation and operation of the P-63 FPSO for the first three years of production starting in 2013. The field is to be produced using dry tree wells located at the adjacent P-61 tension leg platform (TLP) and subsea wells flowing to the P-63 floating production storage and offloading (FPSO) vessel. Production processing facilities are located primarily on the FPSO with multiple fluid transfer lines directing raw produced fluids from P-61 to P-63 for processing. The oil is a heavy crude with low associated gas, high viscosity, and emulsion forming tendency, all of which had significant impact on the equipment and piping design. The low GOR, relatively high power consumption, and location of the facility required the generators and ships boilers be capable of operating with stabilised crude as one of the fuel sources. In addition to the design issues noted, supply chain management challenges had to be overcome due to a contractual stipulation that required 65% Brazilian content. This paper will discuss some of the significant challenges that were faced and the solutions implemented to meet them including: Effects of heavy, high viscosity crude and emulsion on equipment selection and sizing, and piping sizing and layout; limited gas availability as production declines and the effect on power generation/drivers; use of reciprocating engine drivers for power generation; material selection; and interface management among the contractors involved.

    Full Text Available Abstract Background There are numerous ethical challenges that can impact patients and families in the health care setting. This paper reports on the results of a study conducted with a panel of clinical bioethicists in Toronto, Ontario, Canada, the purpose of which was to identify the top ethical challenges facing patients and their families in health care. A modified Delphi study was conducted with twelve clinical bioethicist members of the Clinical Ethics Group of the University of Toronto Joint Centre for Bioethics. The panel was asked the question, what do you think are the top ten ethical challenges that Canadians may face in health care? The panel was asked to rank the top ten ethical challenges throughout the Delphi process and consensus was reached after three rounds. Discussion The top challenge ranked by the group was disagreement between patients/families and health care professionals about treatment decisions. The second highest ranked challenge was waiting lists. The third ranked challenge was access to needed resources for the aged, chronically ill, and mentally ill. Summary Although many of the challenges listed by the panel have received significant public attention, there has been very little attention paid to the top ranked challenge. We propose several steps that can be taken to help address this key challenge.

    Full Text Available Despite the various efforts to enable Kiswahili usage in Information and Communication Technologies (ICT, users of Kiswahili language in ICT have continued to face various challenges. This paper discusses the various challenges that face Kiswahili usage in ICT in two New Partnership for Africa’s Development (NEPAD sponsored schools in Kenya that use Microsoft software’s: Chavakali and Maranda Boy’s secondary schools. This study is guided by a model developed from a combination of two theories: Use and Gratification theory and Symbolic Interaction theory. Data from the two schools are analyzed using qualitative and quantitative analysis. The Data for this work came from 120 students selected through random sampling and 8 teachers of Kiswahili selected through saturated sampling technique. From the analysis of the responses from the study it is evident that Kiswahili usage in ICT is faced by various challenges. Major challenges included negative attitude towards Kiswahili language, difficult technological terms, limited number of those using Kiswahili in ICT, wrong usage of Kiswahili in ICT, English preference and limited research work written in Kiswahili in the internet. Others were limited Kiswahili programs, being forced to use correct Kiswahili, and Kiswahili not being accepted by English programs. The study notes that these challenges need to be addressed. Therefore, recommendations are made on how to overcome the challenges.

    Developing countries like India require a huge infrastructure to facilitate needs of the people. Construction industry provides several opportunities to the individuals. Construction manager work is to supervise and organize the construction activities in construction projects. Now a day construction manager facing challenges. This paper aimed to study the challenges facing by the construction manager in the perception of construction professionals. 39 variables were taken from the literature review which found to be severe impact on construction managers’ performance. Construction manager, project manager and site engineers are the respondents for this survey. Using SPSS, regression analysis was done and recognized significant challenges. These challenges were classified into 5 domains. In management challenges, resource availability and allocation, risks and uncertainties existing in the project onsite, top management support and cost constraints are the most significant variables. In skills requirement of a construction manager challenges, technical skills required to learn and adapt new technology in the project, decision making and planning according to the situation in site are the most significant variables. In performance challenges, implementation of tasks according to the plan is the important variable whereas in onsite challenges, manage project risks, develop project policies and procedures are the most important.

    Ethics is key to the integrity of the veterinary profession. Despite its importance, there is a lack of applied research on the range of ethical challenges faced by veterinarians. A three round Policy Delphi with vignette methodology was used to record the diversity of views on ethical challenges faced by veterinary professionals in Ireland. Forty experts, comprising veterinary practitioners, inspectors and nurses, accepted to participate. In round 1, twenty vignettes describing a variety of ethically challenging veterinary scenarios were ranked in terms of ethical acceptability, reputational risk and perceived standards of practice. Round 2 aimed at characterising challenges where future policy development or professional guidance was deemed to be needed. In round 3, possible solutions to key challenges were explored. Results suggest that current rules and regulations are insufficient to ensure best veterinary practices and that a collective approach is needed to harness workable solutions for the identified ethical challenges. Challenges pertaining mostly to the food chain seem to require enforcement measures whereas softer measures that promote professional discretion were preferred to address challenges dealing with veterinary clinical services. These findings can support veterinary representative bodies, advisory committees and regulatory authorities in their decision making, policy and regulation. British Veterinary Association.

    Bernardes, Margarida Maria Rocha; Lopes, Gertrudes Teixeira

    2007-01-01

    This historic-sociologic study aims to analyse the challenges faced by the Brazilian Expeditionary Force's Air Transportation Nurses of the Army with the Theatre of Operations on the course of World War II. The primary source was comprised of a photograph from this time period and oral testimonies of those who participated in the conflict. Ideas by sociologist Pierre Bourdieu support the discussion. Results suggest that Brazilian nurses were challenged to transport the wounded without medical advice. We conclude that the challenge to fulfill the task imposed, which led to independent decision-making, gave confidence and autonomy to the ones already responsible for the transportation of the wounded.

    Full Text Available Background: Until recently, procurement was seen as a necessity only. In fact, in many developing economies the profession is still being treated as a ‘back-office’ function. However, not much has been done to explore and address challenges facing procurement professionals in developing economies.Objectives: The purpose of this article was to examine the critical role played by the procurement function in business and to reveal the challenges faced by procurement professionals in developing economies as well as to suggest solutions to these challenges.Method: A sequential literary analysis was used, complemented by cross-country qualitative data gathered from one hundred diverse procurement practitioners from Botswana, Namibia and Zimbabwe. These were primarily participants in a series of procurement workshops run by the researchers from January to June 2014.Results: Findings suggested that limited recognition, increasing unethical behaviour, poor supplier service delivery, poor regulatory environment, varying supplier standards and poor corporate governance are the main challenges faced by the procurement profession in these countries.Conclusion: The study’s findings imply that there is limited understanding regarding the role procurement plays in both government and non-government institutions in developing economies. The article suggests solutions which procurement professionals and organisations can implement in order to unlock the potential value in the procurement function.

The main elements of our study are: the relationship between the audit committee and regulatory authority; quality of financial reporting for financial market entities. The auditor plays an important role in financial markets because it certifies the financial statements in accordance with European Union practice . It is also interesting to note potential interference that can occur in single regulation between compliance audit and financial stability and return on investment between performance audit and financial markets.In this case, financial regulation can coexist with compliance audit. EU legislation recommends that the auditor discuss with the audit committee the quality and acceptability of the financial reporting process.This recommendation is what should constitute a possible consensus to be highly unlikely between audit committees would align auditors in financial reporting disputes with management financial entities. In this regard, auditors should identify the factors we consider important in determining the quality of financial reporting. .We conducted this research in an effort to identify the possible divergence between the type of regulations that can emit single regulatory authority and the audit process. New regulator will operate on two levels, issue general regulations apply to all three categories of financial markets, capital market, insurance market and private pensions market, but in the same time and in greater extent will issue specific regulations of each market in

    deformation in Earth's crust, Earth's response to moderate sized earthquakes occurring hundreds of kilometers away, and further new software development to handle these new, massive, datasets provided by the EarthScope program. The culmination of these efforts allowed me a much smoother path toward tenure, given that the CAREER grant enabled new directions and production through integration of my teaching and research (as well as my national service to the EarthScope program). The challenges to this integration were quite modest given that I was able to fold my group's research directly into some of my teaching. Finally, while the program is very good at present, I will present a few ideas for program improvement. For example, it is essential that NSF continue to fully inform and educate peer reviewers of the special nature of CAREER awards, since it is a major challenge for most reviewers to fully and adequately judge both research and teaching. Further, because of the unique nature of the CAREER proposal, NSF might consider extending the length of the proposal by 2-3 pages to provide additional room for extended project timelines, etc.

  15. Natural glide slab avalanches, Glacier National Park, USA: A unique hazard and forecasting challenge

    In a museum of avalanche phenomena, glide cracks and glide avalanches might be housed in the “strange but true” section. These oddities are uncommon in most snow climates and tend to be isolated to specific terrain features such as bedrock slabs. Many glide cracks never result in avalanches, and when they do, the wide range of time between crack formation and slab failure makes them highly unpredictable. Despite their relative rarity, glide cracks and glide avalanches pose a regular threat and complex forecasting challenge during the annual spring opening of the Going-to-the-Sun Road in Glacier National Park, U.S.A. During the 2006 season, a series of unusual glide cracks delayed snow removal operations by over a week and provided a unique opportunity to record detailed observations of glide avalanches and characterize their occurrence and associated weather conditions. Field observations were from snowpits, crown profiles and where possible, measurements of slab thickness, bed surface slope angle, substrate and other physical characteristics. Weather data were recorded at one SNOTEL site and two automated stations located from 0.6-10 km of observed glide slab avalanches. Nearly half (43%) of the 35 glide slab avalanches recorded were Class D2-2.5, with 15% Class D3-D3.5. The time between glide crack opening and failure ranged from 2 days to over six weeks, and the avalanches occurred in cycles associated with loss of snow water equivalent and spikes in temperature and radiation. We conclude with suggest ions for further study.

    Full Text Available Background: Parenting children with learning disabilities requires a high level of knowledge and access to resources, information and services. In developing countries, however, these resources and services are not always available. Parents in Namibia, a developing country, therefore face challenges addressing children’s learning and other developmental disabilities, including challenges related to preventative and supportive interventions.Objective: This research focuses on challenges faced by parents as they parent children with learning disabilities in Opuwo, Namibia.Method: In-depth interviews were conducted with eight parents regarding the challenges they face in parenting their children with learning disabilities. Thematic analysis enabled the researchers to identify, analyse and report on themes that emerged from the qualitative interview data.Results: Analysis of the interviews indicated that some participants had only a vague understanding of learning disabilities, as they did not have access to essential knowledge about this phenomenon. They also lacked an awareness of the availability of programmes, services and policies meant to benefit their children with learning disabilities. Participants voiced that they, their children with learning disabilities and community members have stereotypes and prejudices regarding learning disabilities. In this study, most of the children with learning disabilities were raised by single, unemployed parents who seemed to have access to less support from external sources than married couples parenting children with learning disabilities. These single parents are usually not married and because of lack of financial support from the other parent, the majority of them indicated that they struggle to meet the financial and material needs of their children.Conclusion: The researchers concluded that the participants in this study experience a range of challenges in parenting their children with learning

    Warfare takes a profound toll of all layers of society, creating multiple and multilevel challenges that impinge on the psychosocial well-being of affected individuals. This study aims to assess the scope and salience of challenges confronting former child soldiers and at identifying additional challenges they face compared to non-recruited young people in war-affected northern Uganda. The study was carried out with a stratified random sample of northern Ugandan adolescents (n = 1,008), of whom a third had formerly been recruited (n = 330). The mixed-method comparison design consisted of a constrained free listing task to determine the challenges; a free sorting task to categorize them into clusters; and statistical analysis of their prevalence among formerly recruited youth and of how they compare with those of nonrecruited youth. Altogether, 237 challenges were identified and clustered into 15 categories, showing that formerly recruited participants mainly identified "emotional" and "training and skills"-related challenges. Compared with nonrecruited counterparts, they reported significantly more "emotional" and fewer "social and relational" challenges, with the exception of stigmatization. Overall, there was similarity between the challenges reported by both groups. The challenges confronting formerly recruited youths reach well beyond the effects of direct war exposure and emerge mainly from multiple influence spheres surrounding them. These challenges are largely shared in common with nonrecruited youths. This multidimensional and collective character of challenges calls for comprehensive psychosocial interventions through which healing the psychological wounds of war is complemented by mending the war-affected surroundings at all levels and in all life areas.

    Estimating the anthropogenic component of carbon dioxide emissions from direct atmospheric measurements is difficult, due to the large natural carbon dioxide fluxes. One way of determining the fossil fuel component of atmospheric carbon dioxide is the use of radiocarbon measurements. Whilst carbon reservoirs with a reasonably fast carbon exchange rate all have a similar radiocarbon content, fossil fuels are completely devoid of radiocarbon due to their age. Previous studies have 14CO2 (UK) this approach is compromised by the high density of 14CO2 emitting nuclear power plants. Of the 16 nuclear reactors in the UK, 14 are advanced gas cooled reactors, which have one of the highest 14CO2 emission rates of all reactor types. These radiocarbon emissions not only lead to a serious underestimation of the recently added fossil fuel CO2, by masking the depletion of 14C in CO2, but can in fact overshadow the depletion by a factor of 2 or more. While a correction for this enhancement can be applied, the emissions from the nuclear power plants are highly variable, and an accurate correction is therefore not straightforward. We present the first attempt to quantify UK fossil fuel CO2 emissions through the use of 14CO2. We employ a sampling strategy that makes use of a Lagrangian particle dispersion model, in combination with nuclear industry emission estimates, to forecast "good" sampling times, in an attempt to minimize the correction due to emissions from the nuclear industry. As part of the Greenhouse gAs Uk and Global Emissions (GAUGE) project, 14CO2measurements are performed at two measurement sites in the UK and Ireland, as well as during science flights around the UK. The measurement locations have been chosen with a focus on high emitting regions such as London and the Midlands. We discuss the unique challenges that face the determination of fossil fuel emissions through radiocarbon measurements in the UK and our sampling strategy to deal with them. In addition we

    Full Text Available Background: Despite the relatively high expenditure on healthcare in Saudi Arabia, its health system remains highly centralized in the main cities with its primary focus on secondary and tertiary care rather than primary care. This has led to numerous ethical challenges for the healthcare providers. This article reports the results of a study conducted with a panel of practitioners, and non-clinicians, in Saudi Arabia, in order to identify the top ten ethical challenges for healthcare providers, patients, and their families. Materials and Methods: The study design was a cross-sectional, descriptive, and qualitative one. The participants were asked the question: "What top ten ethical challenges are Saudis likely to face in health care?" The participants were asked to rank the top ten ethical challenges throughout a modified Delphi process, using a ranking Scale. A consensus was reached after three rounds of questions and an experts′ meeting. Results: The major 10 ethical issues, as perceived by the participants in order of their importance, were: (1 Patients′ Rights, (2 Equity of resources, (3 Confidentiality of the patients, (4 Patient Safety, (5 Conflict of Interests, (6 Ethics of privatization, (7 Informed Consent, (8 Dealing with the opposite sex, (9 Beginning and end of life, and (10 Healthcare team ethics. Conclusion: Although many of the challenges listed by the participants have received significant public and specialized attention worldwide, scant attention has been paid to these top challenges in Saudi Arabia. We propose several possible steps to help address these key challenges.

    Because the faces and eyes of primates convey a rich array of social information, the way in which primates view faces and eyes reflects species-specific strategies for facial communication. How are humans and closely related species such as great apes similar and different in their viewing patterns for faces and eyes? Following previous studies comparing chimpanzees (Pan troglodytes) with humans (Homo sapiens), this study used the eye-tracking method to directly compare the patterns of face and eye scanning by humans, gorillas (Gorilla gorilla), and orangutans (Pongo abelii). Human and ape participants freely viewed pictures of whole bodies and full faces of conspecifics and allospecifics under the same experimental conditions. All species were strikingly similar in that they viewed predominantly faces and eyes. No particular difference was identified between gorillas and orangutans, and they also did not differ from the chimpanzees tested in previous studies. However, humans were somewhat different from apes, especially with respect to prolonged eye viewing. We also examined how species-specific facial morphologies, such as the male flange of orangutans and the black-white contrast of human eyes, affected viewing patterns. Whereas the male flange of orangutans affected viewing patterns, the color contrast of human eyes did not. Humans showed prolonged eye viewing independently of the eye color of presented faces, indicating that this pattern is internally driven rather than stimulus dependent. Overall, the results show general similarities among the species and also identify unique eye-viewing patterns in humans.

    Schmidt, Reiner

    1999-01-01

    An upgraded safety concept for CMS has been adapted to the size of the project and its organisational challenges under today's budgetary constraints, as well as to the increasing levels of risk. Strong magnetic fields and high radiation levels, including neutrons, pose additional hazards to materials, to operators, to maintenance and to ultimate deposit of activated materials. CMS also fits the insurer's risk-description for modern facilities, i.e. characterised by "higher energy density, more combustible materials and unattended operation". The regulatory environment, consisting essentially of CERN's autonomous regulations as well as of those of its host countries, also need to be satisfied with much attention. To face this challenge, seven distinct safety management tools have been identified, which are described in some detail, namely clear safety objectives, documented safety requirements, open items list, safety ( and design)reviews, safety risk analysis, enforcement of compliance and quality management....

    Objective. This study explores the challenges faced by the research implementation team in engaging new mothers in a community oral health prevention intervention in an American Indian (AI) reservation community. Methods. Qualitative methods in the form of in-depth interviews were used in the study. Qualitative data were collected from research staff workers at a field site, who were involved in the implementation of a culturally tailored, randomized controlled trial of a behavioral intervention utilizing Motivational Interviewing (MI). Results. Several challenges were described by the field staff in engaging new mothers, including low priority placed on oral health, lack of knowledge, and distractions that reduced their ability to engage in learning about oral health of their child. Other difficulties faced in engaging the mothers and the AI community at large were distrust related to racial differences and physical and environmental barriers including poor road conditions, lack of transportation and communication, and remoteness of data collection sites. The field staff developed and applied many strategies, including conducting home visits, applying new communication strategies, and interacting with the community at various venues. Conclusion. Prevention interventions for ECC need to target AI mothers. Strategies developed by the field staff were successful for engaging mothers in the study.

    Full Text Available There is mounting evidence of the rising incidence and prevalence of non-communicable diseases in developing countries. Governments are facing serious challenges in health care due to the rising trends in non-communicable diseases as a result of demographic and epidemiological changes, as well as economic globalization. Cardiovascular disease, cancers, diabetes, respiratory disease, obesity andother non-communicable conditions now account for 59 percent of the 56.5 million global deaths annually, and almost half, or 46 percent, of the global burden of disease. It is estimated that by 2020, non-communicable diseases will account for 60% of the global burden of disease. The burden of non-communicable diseases in sub-Saharan Africa is already substantial, and patients with these conditions make significant demands on health resources. How do these changes affect physiotherapists? This paper aims to highlight the need for physiotherapists to shift their focus from curative to preventive care in order to face the challenge of non-communicable diseases.

    Full Text Available Although the maternal mortality ratio has descended in Bolivia from 416 (1989 to 229 deaths (DHS 2003 per one hundred thousand live births, it is one of the highest in the region. As a national average, the ratio conceals the rural-urban, socio-economics differences and the reality of the indigenous population. Maternal mortality is one of the major challenges at national level. Reduction of maternal mortality, in addition of technical-medical measures offering health services, requires to focus on socio-cultural aspects that hamper the access to health services. This article examines challenges faced by indigenous mothers accessing the health services. In addition to the geographic, economic and administrative barriers that generate delays in access to the health services, there are others that are presented in the context of multiculturalism resulting from discriminatory attitudes exercised in health centers. The testimonies of indigenous mothers show delays faced in health centers because of prejudice and discrimination suffered, threatening the lives of mothers and their babies. The study also suggests the need to deepen the concept of multiculturalism as a successful strategy in health, in order to promote equity and social justice on the horizon of more inclusive societies.

    Chronic Kidney Disease disproportionately affects the poor in Low and Middle Income Countries (LMICs). Mexico exemplifies the difficulties faced in supporting Renal Replacement Therapy (RRT) and providing equitable patient care, despite recent attempts at health reform. The objective of this study is to document the challenges faced by uninsured, poor Mexican families when attempting to access RRT. The article takes an ethnographic approach, using interviewing and observation to generate detailed accounts of the problems that accompany attempts to secure care. The study, based in the state of Jalisco, comprised interviews with patients, their caregivers, health and social care professionals, among others. Observations were carried out in both clinical and social settings. In the absence of organised health information and stable pathways to renal care, patients and their families work extraordinarily hard and at great expense to secure care in a mixed public-private healthcare system. As part of this work, they must navigate challenging health and social care environments, negotiate treatments and costs, resource and finance healthcare and manage a wide range of formal and informal health information. Examining commonalities across pathways to adequate healthcare reveals major failings in the Mexican system. These systemic problems serve to reproduce and deepen health inequalities. A system, in which the costs of renal care are disproportionately borne by those who can least afford them, faces major difficulties around the sustainability and resourcing of RRTs. Attempts to increase access to renal therapies, therefore, need to take into account the complex social and economic demands this places on those who need access most. This paper further shows that ethnographic studies of the concrete ways in which healthcare is accessed in practice provide important insights into the plight of CKD patients and so constitute an important source of evidence in that effort.

    A proportion of trauma patients present for evaluation in a delayed fashion after injury, likely due to a variety of medical and nonmedical reasons. There has been little investigation into the characteristics and outcomes of trauma patients who present delayed. We hypothesize that trauma patients who present in a delayed fashion are a unique population at risk of increased trauma-related complications. This was a retrospective review from 2010-2015 at a Level I trauma center. Patients were termed delayed if they presented >24 hours after injury. Patients admitted within 24 hours of their injury were the comparison group. Charts were reviewed for demographics, mechanism, comorbidities, complications and outcomes. A subgroup analysis was done on patients who suffered falls. During the 5-y period, 11,705 patients were admitted. A total of 588 patients (5%) presented >24 h after their injury. Patients in the delayed group were older (65 versus 55 y, P fashion have unique characteristics and are more likely to suffer negative outcomes including substance withdrawal. Future goals will include exploring strategies for early intervention, such as automatic withdrawal monitoring and social work referral for all patients who present in a delayed fashion.

    Full Text Available Objectives:Despite the advent of antiretroviral therapy (ART, many children, particularly in the rural communities of Zimbabwe, remain vulnerable. The purpose of this study was to determine the factors and challenges facing children on antiretroviral therapy (ART in Brunapeg area of Mangwe District, Zimbabwe.Methods:A mixed-method approach involving interviewer-guided focus group discussions and piloted semi-structured questionnaires was utilized to collect data from different key population groups. The data obtained were analyzed through content coding procedures based on a set of predetermined themes of interest.Results:A number of challenges emerged as barriers to the success of antiretroviral therapy for children. Primary care givers were less informed about HIV and AIDS issues for people having direct impact on the success of antiretroviral therapy in children whilst some were found to be taking the antiretroviral drugs meant for the children. It also emerged that some primary care givers were either too young or too old to care for the children while others had failed to disclose to the children why they frequently visited the Opportunistic Infections (OI clinic. Most primary care givers were not the biological parents of the affected children. Other challenges included inadequate access to health services, inadequate food and nutrition and lack of access to clean water, good hygiene and sanitation. The lack of community support and stigma and discrimination affected their school attendance and hospital visits. All these factors contributed to non-adherence to antiretroviral drugs.Conclusions and Public Health Implications:Children on ART in rural communities in Zimbabwe remain severely compromised and have unique problems that need multi-intervention strategies both at policy and programmatic levels. Effective mitigating measures must be fully established and implemented in rural communities of developing countries in the fight for

  19. Rural teachers' views: What are gender-based challenges facing Free Primary Education in Lesotho?

    2013-01-01

    Full Text Available This paper gives prominence to rural teachers' accounts of gender-based challenges facing Free Primary Education in Lesotho. It draws on feminist interpretations of social constructionism to discuss factors within the Basotho communities that affect gender equality in the schools. The inductive analysis offered makes use of the data generated from semi-structured interviews with 12 teachers in three primary schools. Basotho culture, superstitious symbolism, and family dynamics are found to be some of the factors that reinforce inequitable gender relations. The findings indicate how teachers exploited these factors to promote the polarisation of gender qualities, and to exalt masculinities at the expense of femininities. The paper argues for the promotion of counter-hegemonic discourses of gender, with an emphasis on conceptions of gender as multiple and fluid human qualities. It explains how paying attention to the cultural architecture of gender formations in localised contexts could become an effective strategy in promoting gender equality in schools.

    Underdevelopment of bond markets is one of the factors contributing to the vulnerability of financial systems in Asian countries. Due to over-reliance on bank loans, it has not been possible for savings in Asia to be invested directly in enterprises rather than being funneled to international financial centers in theU.S, and Europe and then back to Asia. When there is a crisis, enterprises and financial institutions are faced with both “mismatch in maturity of loans” and “mismatch in currency denomination” in their funding positions. The risks inherent in the dual mismatches are sources offinancial instability in Asia. Therefore there has been a consensus among major Asian countries to foster Asian bond markets in order to reduce these risks. For China, developing its domestic bond market has become an important part of effort to participate in fostering Asian bond markets. Based on proposals and recent development of Asian bond markets, this paper discusses the problems and challenges faced by China in developing domestic bond markets.

  1. Supply constraints : Australia and Canada coal industry face logistics and capacity challenges

    Australia and Canada are benefiting from a global increase in coal consumption, but face challenges regarding coal and coal export capacity. Coal is Australia's biggest export commodity, accounting for over 50 percent of world coking coal exports, with almost 75 percent of those exports destined for Asian markets, primarily Japan. However, the number of ships delayed at Australian ports hit a record of 223 bulk carriers in early 2010. Compared to Canada, Australia faces greater logistical issues getting coal into port and onto ships at its 9 loading terminals. Two of Canada's 3 major shipping terminals, Westshore and Neptune, have some additional capacity. Its third terminal, Ridley Island, has considerable potential to carry more coal. With 98 percent of all coal moved by rail in Australia, rail issues also hinder growth. A national approach to planning freight transport on both roads and rail is being developed. While infrastructure issues remain the single greatest barrier to export growth for Australia's coal sector, Canada's most immediate issues pertain to mine permitting and mine-site expansion. In 2009, Canada exported 28 million tonnes of coal, 90 percent of it metallurgical. With approximately 70 million tonnes of annual production, mostly in British Columbia and Alberta, coal remains the number one commodity in Canada carried by rails and shipped from ports. 1 fig.

  2. Challenges of microtome-based serial block-face scanning electron microscopy in neuroscience.

    2015-08-01

    Serial block-face scanning electron microscopy (SBEM) is becoming increasingly popular for a wide range of applications in many disciplines from biology to material sciences. This review focuses on applications for circuit reconstruction in neuroscience, which is one of the major driving forces advancing SBEM. Neuronal circuit reconstruction poses exceptional challenges to volume EM in terms of resolution, field of view, acquisition time and sample preparation. Mapping the connections between neurons in the brain is crucial for understanding information flow and information processing in the brain. However, information on the connectivity between hundreds or even thousands of neurons densely packed in neuronal microcircuits is still largely missing. Volume EM techniques such as serial section TEM, automated tape-collecting ultramicrotome, focused ion-beam scanning electron microscopy and SBEM (microtome serial block-face scanning electron microscopy) are the techniques that provide sufficient resolution to resolve ultrastructural details such as synapses and provides sufficient field of view for dense reconstruction of neuronal circuits. While volume EM techniques are advancing, they are generating large data sets on the terabyte scale that require new image processing workflows and analysis tools. In this review, we present the recent advances in SBEM for circuit reconstruction in neuroscience and an overview of existing image processing and analysis pipelines.

    Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. Both junior and senior mission control personnel have had to find ways to address the cultural challenges inherent in such work, but neither have had systematic training in how to do so. The goals of this study were to identify and evaluate the major cultural challenges faced by ISS mission control personnel and to highlight the approaches that they have found most effective to surmount these challenges. We pay particular attention to the approaches successfully employed by the senior personnel and the training needs identified by the junior personnel. We also evaluate the extent to which the identified approaches and needs are consistent across the two samples. METHODS: Participants included a sample of 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers. All participants were mission operations specialists chosen on the basis of having worked extensively with international partners. Data were collected using a semi-structured qualitative interview and content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. RESULTS: The senior respondents had substantial consensus on several cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Data from the junior respondents will be presented for the first time at the meeting. DISCUSSION: Although specific to American ISS personnel, our results are consistent with recent management, cultural, and aerospace research on other populations. We aim to use our results to improve training for current and future mission control personnel working in international or multicultural mission operations teams.

  4. Acoustic environment challenges for the unique communication conditions in group learning classes in elementary school classrooms

    2005-04-01

    Unlike the traditional ``sage-on-the-stage'' configuration of many K-12 classrooms, the group learning or ``guide-on-the-side'' configuration does not involve communication between a teacher in front of a seated class of 20 to 30 students. Instead, it can involve, most of the time, communication between the teacher and each of several small groups of students interacting, aurally, with each other. To maintain the desired 15 dB signal-to-noise ratio intended as the rationale for the ANSI standard, S12.60-2002 on classroom acoustics, the ``noise'' heard by participants in one of the groups is likely to include the speech levels generated by the participants in the other groups as well as the background noise in the unoccupied classroom. Thus, specification of the speech level within (i.e. the ``signal''), and between (i.e. part of the ``noise'') the learning groups, must be considered. Data available to evaluate these speech levels are reviewed and possible models considered to account for the Lombard effect for voice levels of both the teacher and the students. Some of the gaps in these data are suggested as a challenge to stimulate further studies on speech levels of teachers and students in a wide range of communication conditions.

    Full Text Available The Professional Executive Secretary has been occupying space increasingly evident in the labor market and organizational structure, both because of market demand, the needs of dynamism in the modern administration that demonstrates the growth of the reference to it. It has sought in his field vision and attitude of performance excellence with fulfilling its role with its own characteristics. This study aims to investigate the general challenges for the Executive Secretariat professional male in contemporary organizations. We defined the following objectives: to analyze the insertion of the male in the profession of Executive Secretary and identify the challenges faced by the Executive Secretary of the males to their development and professional growth. To this end, we performed a literature search, followed by a field survey. It is a qualitative research because data collected, and then make a qualitative analysis of results from selected literature. The survey was conducted in organizations from the public and private, state of Ceará. The sample was represented by professional male graduates in the executive secretariat at the Federal University of Ceará and working in the area. After analyzing the data it was concluded that despite the obstacles to be overcome, the tendency is that these opportunities work for the professional male grow, requiring that all actors in the field to seek gender equity in the profession.

  6. Are we facing new health challenges and diseases in reindeer in Fennoscandia?

    Full Text Available A large number of semi-domesticated reindeer is lost every year. Predators are the single most important factor for these losses, whereas restrictions on food availability some years also may cause high mortality. In the past, reindeer herding was challenged by severe infectious diseases, killing hundreds and thousands of animals, and having huge economic and social impact on reindeer herding in Fennoscandia. The general zoo-sanitary situation in Fennoscandia is very favourable for the time being, but reindeer herding is sometimes challenged by disease outbreaks, and diseases play an important role for survival and fitness of reindeer. Reindeer herding is also facing changes and challenges, which also may impact reindeer health and the disease status. Introduction of infectious agents not commonly present in the reindeer population may take place through import of animals, as well as by contact between reindeer, livestock and wildlife. Further, changes in the herding, such as increased feeding, transport, size of herds, animal density and stress load on the animals, may affect the animals ability to cope with infectious diseases. Also changes in weather conditions and climate, such as increased precipitation and mean temperature, may over time lead to restricted availability of pastures, changes in vegetation and changed conditions for parasites and insect vectors. These changes might be especially important for the reproductive success, including fitness of the calves during their first winter. To be able to cope with these changes and their potential impact on reindeer health, increased efforts should be made to gather reference data on health and disease parameters from the different reindeer herding districts, along with epidemiological risk factor analysis. This would increase the ability for the reindeer herding to cope with changes and to continue to produce quality meat products for the market.

    The literature outlines many challenges faced by Student-Teacher-Scientist Partnerships (STSPs) including cultural differences between the scientific research and education communities. For example, shared vocabulary terms with dissimilar definitions can create communication problems. Other issues include accuracy in data collection, meeting the needs of a very diverse group of partners, connecting students with research science in a meaningful way, and maintaining the infrastructure necessary to develop and maintain these partnerships. Additionally, evidence, other than anecdotal, of the success of these partnerships is limited, especially as school year and research cycles are often on different schedules or have very different goals. Students, Teachers, and Rangers & Research Scientists: Investigating Systems at Mammoth Hot Springs in Yellowstone National Park (STaRRS) was an STSP developed to address some of these challenges, model some solutions within an STSP, and identify some possible outcomes for participating teachers and their students. Three strategies used to address some of these challenges that will be discussed briefly in this presentation include: (a) embedding the STSP in an already existing National Park Service environmental education program; (b) development of three types of research activities connecting teachers, students, and scientists to the research, and (c) a professional development (PD) model that included all partners in an on-going year-long process. Results from an accompanying research study will also be presented. Using a pretest-intervention-posttest design, this study revealed significant changes in attitude regarding science and scientists of participating STaRRS teachers. Student data gathered using a quasi-experimental pretest-intervention-posttest treatment and comparison group design also demonstrated significant changes in their attitudes and gains in earth science content knowledge.

    Bioenergy is increasingly used to help meet greenhouse gas (GHG) and renewable energy targets. However, bioenergy's sustainability has been questioned, resulting in increasing use of life cycle assessment (LCA). Bioenergy systems are global and complex, and market forces can result in significant changes, relevant to LCA and policy. The goal of this paper is to illustrate the complexities associated with LCA, with particular focus on bioenergy and associated policy development, so that its use can more effectively inform policymakers. The review is based on the results from a series of workshops focused on bioenergy life cycle assessment. Expert submissions were compiled and categorized within the first two workshops. Over 100 issues emerged. Accounting for redundancies and close similarities in the list, this reduced to around 60 challenges, many of which are deeply interrelated. Some of these issues were then explored further at a policy-facing workshop in London, UK. The authors applied a rigorous approach to categorize the challenges identified to be at the intersection of biofuels/bioenergy LCA and policy. The credibility of LCA is core to its use in policy. Even LCAs that comply with ISO standards and policy and regulatory instruments leave a great deal of scope for interpretation and flexibility. Within the bioenergy sector, this has led to frustration and at times a lack of obvious direction. This paper identifies the main challenge clusters: overarching issues, application and practice and value and ethical judgments. Many of these are reflective of the transition from application of LCA to assess individual products or systems to the wider approach that is becoming more common. Uncertainty in impact assessment strongly influences planning and compliance due to challenges in assigning accountability, and communicating the inherent complexity and uncertainty within bioenergy is becoming of greater importance. The emergence of LCA in bioenergy governance is

    2007-12-15

    A national survey was made at the 2008 la Baule Symposium 'nuclear medicine facing major public health challenges'. The aim was to evaluate the activity in the fields of clinical specialities involved in these challenges : cancerology, cardiology and neurology. The response rate was 62%. The total number of PET scans performed in France during the year 2007 was about 100,000 including 97.5% of cancer indications. The mean number of PET scans per center was 1285, with a maximum of 3500 scans. The first indications were lung cancer (27%), lymphoma (20%) and colorectal cancer (14%). The registered number of cardiac examinations was 170,387 extrapolated to a total number of about 250,000 examinations in one year. The number of registered brain SPECT was 11,215 corresponding to about 100 examinations per center in one year. The survey pointed out large variations of PET activity between centers and suggested potentialities in extending and diversifying the field of PET. Brain scintigraphy appeared as a minor sector out of proportion with the challenge of degenerative brain pathology. Performing again these evaluations in the next years should allow to better describe the capabilities of nuclear medicine to face the major challenges and the evolution of public health.

    Through the interplay of a stabilising cold-water coral framework and a dynamic sedimentary environment, cold-water coral carbonate mounds create distinctive centres of bio-geological accumulation in often complex (continental margin) settings. The IODP Expedition 307 drilling of the Challenger Mound (eastern Porcupine Seabight; NE Atlantic) not only retrieved the first complete developmental history of a coral carbonate mound, it also exposed a unique, Early-Pleistocene sedimentary sequence of exceptional resolution along the mid-latitudinal NE Atlantic margin. In this study, a comprehensive assessment of the Challenger Mound as an archive of Quaternary palaeo-environmental change and long-term coral carbonate mound development is presented. New and existing environmental proxy records, including clay mineralogy, planktonic foraminifer and calcareous nannofossil biostratigraphy and assemblage counts, planktonic foraminifer oxygen isotopes and siliciclastic particle-size, are thereby discussed within a refined chronostratigraphic and climatic context. Overall, the development of the Challenger Mound shows a strong affinity to the Plio-Pleistocene evolution of the Northern Hemisphere climate system, albeit not being completely in phase with it. The two major oceanographic and climatic transitions of the Plio-Pleistocene - the Late Pliocene/Early Pleistocene intensification of continental ice-sheet development and the mid-Pleistocene transition to the more extremely variable and more extensively glaciated late Quaternary - mark two major thresholds in Challenger Mound development: its Late Pliocene (>2.74 Ma) origin and its Middle-Late Pleistocene to recent decline. Distinct surface-water perturbations (i.e. water-mass/polar front migrations, productivity changes, melt-water pulses) are identified throughout the sequence, which can be linked to the intensity and extent of ice development on the nearby British-Irish Isles since the earliest Pleistocene.

    Small geoscience departments with 5 faculty members or less in undergraduate institutions are facing serious challenges that will have a profound impact on their future, as well as the future of geoscience education. In addition to past and future budget cuts that affect all departments, small departments are more vulnerable to such problems as (i) decreased enrollments in introductory level classes, (ii) small number of geology majors, (iii) small number of graduates per year (iv) lack or paucity of equipment necessary for faculty and student research, (v) limited opportunities for external funding, (vi) need to offer upper division classes on an alternate year basis, (vii) difficulty in recruiting and retaining students, (viii) high teaching loads for faculty, and (ix) designing rigorous curricula based on 120 credit hours with a significant component of liberal art classes. These problems pose new challenges for faculty, department chairs and administrators. Faculty need to design curricula tailored to the need of the job market, without compromising rigor or the quality of the program. New classes/ concentrations in environmental science, hydrogeology and geographical information systems should be offered, and traditional classes in petrology, geophysics and tectonics should be maintained. Classes in Physics, Chemistry and Math should be core requirements. Student involvement in research should be encouraged at an early stage (sophomore/ junior levels). Department chairs need to assign duties in their department carefully to capitalize on the strengths of their faculty: faculty with strong research backgrounds should be helped in their efforts to pursue external funding opportunities, whereas those with strong teaching abilities should be evaluated primarily on their performance in the classroom. Student credit hour production should not be used as a criterion for evaluating faculty. Administrators should evaluate programs and departments based on the success

    The provision of veterinary clinical services is known to elicit a range of challenges which require an ethical appraisal. In a recent Policy Delphi study, referrals/second opinions and 24 h emergency care were identified as matters of key concern by veterinary professionals in Ireland. In this case study (the first in a series of three resulting from a research workshop exploring challenges facing the veterinary profession in Ireland; the other two case studies investigate the on-farm use of veterinary antimicrobials and emergency/casualty slaughter certification) we aim to provide a value-based reflection on the constraints and possible opportunities for two prominent veterinary clinical services in Ireland: referrals/second opinions and 24 h emergency care. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely referral and referring veterinarians, clients, animal charities, and the regulatory body. Six overarching, interrelated constraints emerged from the thematic analysis: the need to improve current guidance, managing clients' expectations, concerns with veterinarian well-being, financial issues, timeliness of referral, and conflicts between veterinary practices. Possible solutions to improve veterinary referral and out-of-hours clinical services included clarifying the terms used in current norms and regulations (namely 'referral', 'second opinion', '24 h emergency care' and '24 h cover'), improved communication (making the client aware of the different levels of veterinary care that are being offered, and transparent and full disclosure of clinical records), and the promotion of Continuing Veterinary Education in communication, business management and ethical decision-making. These findings may help inform the Veterinary Council of Ireland about future recommendations and regulatory measures.

    Full Text Available Innovations in Information technology have changed the way financial transactions are done in banking industry globally. Online banking uses today’s computer technology to give user the ability to manage their finances more quickly and efficiently, from anywhere around the world, and with just a click of the mouse. Banks perceive online banking as a powerful ‘value-added’ tool to attract and retain new customers while helping to eliminate costly paper handling and teller interactions. Online banking has managed to provide customers the convenience, efficiency, effe ctiveness, and most importantly, the speed needed in today’s dynamic world. As more banks around the world are offering online banking to its customers, it is becoming a rather popular trend. Online banking is an asset both to the bank and the customer. However, countries like Sudan are yet to join the frenzy of this new innovation in an effective manner. This paper will investigate what are the challenges faced by Sudanese banks in implementing online banking.

However, for those in the adolescent and young adult (AYA age-group of 15–30 years with ALL, there has not been the same degree of improvement. Historically, pediatric and adult providers have utilized different treatment approaches based on clinical trials. However, studies that have compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have generally shown substantially better outcomes for this patient population treated with the pediatric trials. Additionally, hematopoietic stem cell transplantation has been considered as part of intensified therapy for AYA patients with ALL. Herein, we review the outcomes with chemotherapy alone and with hematopoietic stem cell transplantation, and explore the challenges faced in determining the ideal therapy for the AYA population of patients.

    Veterinarians are faced with significant conflicts of interest when issuing certificates for the transport and slaughter of acutely injured and casualty livestock. In a recent Policy Delphi study, emergency and casualty slaughter certification was a key concern identified by veterinary professionals in Ireland. In this case study (the third in a series of three resulting from a research workshop exploring challenges facing the veterinary profession in Ireland; the other two case studies investigate clinical veterinary services and the on-farm use of veterinary antimicrobials), we aim to provide a value-based reflection on the constraints and opportunities for best practice in emergency and casualty slaughter certification in Ireland. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely a representative from the regulatory body, local authority veterinarians with research experience in emergency slaughter, an animal welfare research scientist, official veterinarians from the competent authority, a private veterinary practitioner, and a member of a farming organisation. Results revealed a conflict between the responsibility of private veterinary practitioners (PVPs) to safeguard the welfare of acutely injured bovines on-farm and the client's commercial concerns. As a consequence, some PVPs may feel under pressure to certify, for example, an acutely injured animal for casualty slaughter instead of recommending either on-farm emergency slaughter or disposal by the knackery service. Among Official Veterinarians, there are concerns about the pressure within processing plants to accept acutely injured livestock as casualty animals. Confusion pertaining to legislation and definition of fitness to travel also contribute to these dilemmas. Conflicts of interest arise due to the gap between governance and provision to facilitate on-farm emergency slaughter of livestock. Increased availability and acceptance of on

    People who leave their country of origin, or the country of habitual residence, to establish themselves permanently in another country are usually referred to as migrants. Over half of all births in Montreal, Canada are to migrant women. To understand healthcare professionals' attitudes towards migrants that could influence their delivery of care, our objective was to explore their perspectives of challenges newly-arrived migrant women from non-Western countries face when needing maternity care. In this qualitative multiple case study, we conducted face-to-face interviews with 63 health care professionals from four teaching hospitals in Montreal, known for providing maternity care to a high volume of migrant women. Interviews were transcribed and thematically analysed. Physicians, nurses, social workers, and therapists participated; 90% were female; and 17% were themselves migrants from non-Western countries. According to participants, newly-arrived migrant women face challenges at two levels: (a) direct care (e.g., understanding Canadian health care professionals' expectations, communicating effectively with health care professionals), and (b) organizational (e.g., access to appropriate health care). Challenges women face are strongly influenced by the migrant woman's background as well as social position (e.g., general education, health literacy, socio-cultural integration) and by how health care professionals balance women's needs with perceived requirement to adhere to standard procedures and regulations. Health care professionals across institutions agreed that maternity care-related challenges faced by newly-arrived migrant women often are complex in that they are simultaneously driven by conflicting values: those based on migrant women's sociocultural backgrounds versus those related to the implementation of Canadian guidelines for maternity care in which consideration of migrant women's particular needs are not priority.

    At present, poor medical service availability, high health care costs and inefficient of public health spending are exsiting in many countries, and health care reform still faces big challenges. To improve people's health and to make a control of the costs are dilemma of health-care reform, and thus improving the efficiency of public health expenditure is the optimal choice to improve social health. The forms of government intervention and the level of public health expenditure are different due to different countries and period. Emerging economies should expand basic health care coverage on the premise of fiscal sustainable development while developed economies should pay attention to improve the public health spending efficiency and limit the spending growth.%当前,许多国家仍存在医疗服务可得性差、医疗成本高昂、公共卫生支出效率低下等问题,医保改革面临重大挑战。医保改革目标存在两难—既要改善人们的健康状况,又要控制支出成本,因而提高公共卫生支出效率是改善社会健康状况的最优选择。各国政府的干预形式和公共卫生支出水平因国别、时间等的不同而变化。财政状况较好的新兴经济体需在保证财政可持续的前提下扩大基本医保覆盖面;发达经济体则应注重提升公共卫生支出的效率并限制支出增长速度。

    Persistent smoking after a cancer diagnosis has adverse effects. Most smoking cessation interventions focus on individual behaviors; however, family members who smoke are major barriers to success. This article describes challenges and lessons learned related to recruitment and retention to a longitudinal, dyadic-centered smoking cessation intervention study for individuals confronting a new diagnosis of thoracic cancer and their family members who smoke. A prospective, one-group repeated measures, mixed-method feasibility study measured recruitment, retention, adherence, and acceptability over a 6-month period in a thoracic surgery clinic at a university cancer center. A multidisciplinary, multi-component decision aid-"Tobacco Free Family"-was used to intervene with the dyads. Study recruitment occurred preoperatively with a thoracic surgery team member assessing smoking status. During the 6-month recruitment period, 50 patients who smoked were screened, and 18 eligible families were approached to participate. Sixteen participants (8 dyads) enrolled. Patients were all male, and participating family members were all female-either spouses or long-term girlfriends. Others types of family members declined participation. Recruitment was lower than anticipated (44%), retention was high (100%), and maximizing convenience was the most important retention strategy. Oncology nurses can assess the smoking status of patients and family members, facilitate understanding about the benefits of cessation, refer those willing to stop to expert resources, and help motivate those unwilling to quit. Research is needed to continue developing strategies to help patients with thoracic cancer and their families facing surgery as an impetus for stopping smoking. Novel intervention delivery and communication need further exploration. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Antimicrobial resistance has emerged in recent years as a significant public health threat, which requires both an ethical and a scientific approach. In a recent Policy Delphi study, on-farm use of antimicrobials was a key concern identified by veterinary professionals in Ireland. In this case study (the second in a series of three resulting from a research workshop exploring the challenges facing the veterinary profession in Ireland; the other two case studies investigate clinical veterinary services and emergency/casualty slaughter certification) we aim to provide a value-based reflection on the constraints and possible opportunities for responsible use of veterinary antimicrobials in Ireland. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely veterinarians working in public and private organisations, a representative from the veterinary regulatory body, a dairy farmer and a general medical practitioner. Three overarching constraints to prudent on-farm use of veterinary antimicrobials emerged from the thematic analysis: 'Defective regulations', 'Lack of knowledge and values' regarding farmers and vets and 'Farm-centred concerns', including economic and husbandry concerns. Conversely, three main themes which reflect possible opportunities to the barriers were identified: 'Improved regulations', 'Education' and 'Herd health management'. Five main recommendations arose from this study based on the perspectives of the study participants including: a) the potential for regulatory change to facilitate an increase in the number of yearly visits of veterinarians to farms and to implement electronic prescribing and shorter validity of prescriptions; b) a 'One Health' education plan; c) improved professional guidance on responsible use of veterinary antimicrobials; d) improved on-farm herd health management practices; and e) the promotion of a 'One Farm-One Vet' policy.

    As an EFL Student teachers’ advisor, I had constantly perceived that they regarded using the target language with their pupils inside their classroom as a challenge. That is why I became interested in investigating how thirteen student teachers in Tunja public schools faced this issue. While participants were involved in a reflective teaching preparation model, I used field notes, interviews and their portfolios to explore their attitudes and strategies. Findings revealed that their history as learners, their teaching context and preparation influenced their decisions. Moreover, it was possible to identify the strategies they implemented to interact in English with their students.

    Exclusive breastfeeding (EBF) has been identified as the optimal nutrition and critical behavior in attaining human immunodeficiency virus (HIV)-free infant survival in resource-limited settings. Health-care providers (HCPs) in clinic- and community-settings throughout sub-Saharan Africa (sSA) provide infant-feeding counseling. However, rates of EBF at 6 months of age are suboptimal. HCPs are uniquely positioned to educate HIV-positive mothers and provide support by addressing known barriers to EBF. However, limited evidence exists on the experiences faced by HCPs in providing counseling on infant feeding to HIV-positive women. Our objective is to describe experiences faced by HCPs when delivering infant-feeding counseling in the context of HIV in program settings in sSA. We searched a range of electronic databases, including PubMed, CINAHL, and PsycINFO from January 1990 to February 2013, in addition to hand-searching, cross-reference searching, and personal communications. The search was limited to publications in English. Empirical studies of HCP experiences providing infant-feeding counseling in the prevention of mother-to-child transmission (PMTCT) of HIV programs in sSA were selected. We identified 10 peer-reviewed articles reporting HCP challenges in infant-feeding counseling that met inclusion criteria. Articles included qualitative, cross-sectional and mixed-method studies, and cumulatively reported 31 challenges faced by HCPs. Among the challenges identified, the most commonly reported were personal beliefs held by the HCPs toward infant feeding in the context of HIV, contradictory messages, staff workload, directive counseling styles, and a lack of practical strategies to offer mothers, often leading to improvised counseling approaches. Counseling strategies need to be developed that are relevant, meaningful, and responsive to the needs of both HCPs and mothers.

  11. Facing policy challenges with inter- and transdisciplinary soil research focused on the UN Sustainable Development Goals

    Our current information society, populated by increasingly well-informed and critical stakeholders, presents a challenge to both the policy and science arenas. The introduction of the UN Sustainable Development Goals (SDGs) offers a unique and welcome opportunity to direct joint activities towards these goals. Soil science, even though it is not mentioned as such, plays an important role in realizing a number of SDGs focusing on food, water, climate, health, biodiversity, and sustainable land use. A plea is made for a systems approach to land use studies, to be initiated by soil scientists, in which these land-related SDGs are considered in an integrated manner. To connect with policy makers and stakeholders, two approaches are functional. The first of these is the policy cycle when planning and executing research, which includes signaling, design, decision making, implementation, and evaluation. Many current research projects spend little time on signaling, which may lead to disengagement of stakeholders. Also, implementation is often seen as the responsibility of others, while it is crucial to demonstrate - if successful - the relevance of soil science. The second approach is the DPSIR approach when following the policy cycle in land-related research, distinguishing external drivers, pressures, impact, and responses to land use change that affect the state of the land in the past, present, and future. Soil science cannot by itself realize SDGs, and interdisciplinary studies on ecosystem services (ESs) provide an appropriate channel to define contributions of soil science in terms of the seven soil functions. ESs, in turn, can contribute to addressing the six SDGs (2, 3, 6, 12, 13, and 15) with an environmental, land-related character. SDGs have a societal focus and future soil science research can only be successful if stakeholders are part of the research effort in transdisciplinary projects, based on the principle of time-consuming "joint learning".

    Full Text Available Background: Women with disabilities in Zimbabwe face numerous challenges in accessing sexual and reproductive health. Cultural belief still regards them as not sexually active. The government has also failed to promote policies that facilitate access to sexual and reproductive services by women with disabilities.Objectives: The reseach objectives were to explore the challenges faced by women with disabilities in accessing sexual and reproductive health in Zimbabwe.Method: The data were gathered using in-depth interviews with 23 purposively selected respondents. Thirteen women had physical disabilities, five were visually impaired, three were deaf and two were stammering. The respondents with physical disabilities were using wheelchairs, walking frames, prosthesis, crutches and caliper shoes. The participants’ ages ranged from 18 to 45 years. All interviews were transcribed and translated verbatim into English, and passages were extracted from the transcripts. Key themes and concepts were identified and coded to offer a rich framework for analysis, comparisons and presentation of the data.Results: Negative perceptions of health personnel towards people with disabilities, disability-unfriendly infrastructure at health facilities and absence of trained personnel for people with disabilities (sign language are some of the challenges involved.Conclusion: The government, in partnership with other stakeholders, should address challenges faced by women with disabilities when accessing sexual and reproductive health services. Non-government, private hospitals and profit-making organisations should join hands with government in funding health requirements for women with disabilities.

Intertextual analysis of the data suggests that traditional product-based approaches to helping students develop academic literacy might not be very effective. However, to be able to take a different approach, such as the one suggested by genre scholars, both faculty teaching content subjects and writing tutors would need appropriate training. Key words: ESL writing, academic writing, academic voice, disciplinary writing Con base en teorías críticas, socioculturales y sociolingüísticas sobre escritura académica, texto y voz, este estudio etnográfico explora los retos que enfrentan una estudiante hablante de inglés como segunda lengua y sus profesores de un curso de Medios de Comunicación en Lengua Española al construir conjuntamente los conceptos de literacias académicas y de voz en un curso de pregrado en estudios generales ofrecido por una universidad en Massachusetts. El análisis intertextual de los datos recogidos muestra que algunos métodos tradicionales dirigidos a la elaboración de productos pueden resultar poco efectivos para apoyar el desarrollo de la escritura académica. Sin embargo, se concluye que para usar metodologías más efectivas, como las propuestas por las teorías de género, es indispensable que tanto los profesores de las diferentes materias como los tutores reciban el entrenamiento adecuado.

    Full Text Available Abstract Background Infant feeding is a subject of worry in prevention of mother to child transmission (pMTCT programmes in settings where breastfeeding is normative. Nurse-counsellors, expected to counsel HIV-positive women on safer infant feeding methods as defined in national/international guidelines, are faced with a number of challenges. This study aims to explore the experiences and situated concerns of nurses working as infant feeding counsellors to HIV-positive mothers enrolled in pMTCT programmes in the Kilimanjaro region, northern Tanzania. Methods A qualitative study was conducted using in-depth interviews and focus group discussions (FGDs with 25 nurse-counsellors at four pMTCT sites. Interviews were handwritten and FGDs were tape-recorded and transcribed, and the programme Open Code assisted in sorting and structuring the data. Analysis was performed using 'content analysis.' Results The findings revealed a high level of stress and frustration among the nurse-counsellors. They found themselves unable to give qualified and relevant advice to HIV-positive women on how best to feed their infants. They were confused regarding the appropriateness of the feeding options they were expected to advise HIV-positive women to employ, and perceived both exclusive breastfeeding and exclusive replacement feeding as culturally and socially unsuitable. However, most counsellors believed that formula feeding was the right way for an HIV-positive woman to feed her infant. They expressed a lack of confidence in their own knowledge of HIV and infant feeding, as well as in their own skills in assessing a woman's possibilities of adhering to a particular method of feeding. Moreover, the nurses were in general not comfortable in their newly gained role as counsellors and felt that it undermined the authority and trust traditionally vested in nursing as a knowledgeable and caring profession. Conclusion The findings illuminate the immense burden placed on

    Full Text Available This paper examines the Nigerian economy and the tendency for its growth in the face of several socio-political challenges facing the country, which have hampered the rate of economic development in spite of the tremendous human and material resources inherent. The paper identifies the socio-political challenges to include corruption, poverty, unemployment, insecurity, politics and governance, among others. The central argument of the paper is that steady economic growth can be achieved and financial crisis mitigated in Nigeria, if the effects of socio-political challenges, which are the key factors that have contributed to the high poverty, unemployment and economic instability in the country, are minimised. To ensure economic growth and move the country forward politically and economically, government must be more accountable in managing the nation’s resources in order to avoid wastage, poverty and unemployment. Close attention should be given to those socio-political challenges in the formulation of policies that aimed at maintaining economic growth at a level commensurate with the country’s growth rate. This study put forward that government must be proactive in all issues relating to the socio-political challenges to prevent resource mismanagement, poverty, unemployment, insecurity and slow economic growth in future.

    The presentation will introduce a french national project : CONVERGENCE that has been funded for four years. This project will tackle big data and computational challenges faced by climate modeling community in HPC context. Model simulations are central to the study of complex mechanisms and feedbacks in the climate system and to provide estimates of future and past climate changes. Recent trends in climate modelling are to add more physical components in the modelled system, increasing the resolution of each individual component and the more systematic use of large suites of simulations to address many scientific questions. Climate simulations may therefore differ in their initial state, parameter values, representation of physical processes, spatial resolution, model complexity, and degree of realism or degree of idealisation. In addition, there is a strong need for evaluating, improving and monitoring the performance of climate models using a large ensemble of diagnostics and better integration of model outputs and observational data. High performance computing is currently reaching the exascale and has the potential to produce this exponential increase of size and numbers of simulations. However, post-processing, analysis, and exploration of the generated data have stalled and there is a strong need for new tools to cope with the growing size and complexity of the underlying simulations and datasets. Exascale simulations require new scalable software tools to generate, manage and mine those simulations ,and data to extract the relevant information and to take the correct decision. The primary purpose of this project is to develop a platform capable of running large ensembles of simulations with a suite of models, to handle the complex and voluminous datasets generated, to facilitate the evaluation and validation of the models and the use of higher resolution models. We propose to gather interdisciplinary skills to design, using a component-based approach, a

    The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

  5. 21st century challenges faced by nursing faculty in educating for compassionate practice: embodied interpretation of phenomenological data.

    Science.gov (United States)

    Curtis, Katherine

    2013-07-01

    Nursing faculty are facing challenges in facilitating student learning of complex concepts such as compassionate practice. Compassion is a stated expectation of Registered Nurse (RN) and student nurse practice, and yet how it is enabled and learned within the challenging environments of university and health service provider organisations are not yet understood. There is currently an international concern that student nurses are not being adequately prepared for compassion to flourish and for compassionate practice to be sustained upon professional qualification. In order to investigate the experiences of nursing faculty in their preparation of student nurses for compassionate practice, an exploratory aesthetic phenomenological research study was undertaken using in depth interviews with five nurse teachers in the North of England. Findings from this study were analysed and presented using embodied interpretation, and indicate that nurse teachers recognise the importance of the professional ideal of compassionate practice alongside specific challenges this expectation presents. They have concerns about how the economically constrained and target driven practice reality faced by RNs promotes compassionate practice, and that students are left feeling vulnerable to dissonance between learned professional ideals and the RNs' practice reality they witness. Nurse teachers also experience dissonance within the university setting, between the pressures of managing large student groups and the time and opportunity required for small group discussion with students that enables compassion to develop in a meaningful and emotionally sustainable way. Teachers also express discomfort due to a perceived promotion of an 'unachievable utopia' within practice, identifying how the constraints within practice could be better managed to support professional ideals. The nurse teachers within this exploratory study identify the need for strong nurse leadership in practice to challenge

    On October 23, 2011, a M7.2 earthquake caused damage in a widespread area in the Van province located in eastern Turkey. This strong earthquake was followed by a M5.7 earthquake on November 9, 2011. This sequence of damaging earthquakes led to 644 fatalities. The management during and after these earthquake disaster imposed many critical challenges. In this article, an overview of these challenges is presented based on the observations by the authors in the aftermath of this disaster. This article presents the characteristics of 2011 Van earthquakes. Afterward, the key information related to the four main phases (ie, preparedness, mitigation, response, and recovery) of the disaster in Van is presented. The potential strategies that can be taken to improve the disaster management practice are identified, and a set of recommendations are proposed to improve the existing situation.

  7. The changing face of nanomaterials: Risk assessment challenges along the value chain.

    Science.gov (United States)

    Mattsson, Mats-Olof; Simkó, Myrtill

    2017-03-01

    Risk assessment (RA) of manufactured nanomaterials (MNM) is essential for regulatory purposes and risk management activities. Similar to RA of "classical" chemicals, MNM RA requires knowledge about exposure as well as of hazard potential and dose response relationships. What makes MNM RA especially challenging is the multitude of materials (which is expected to increase substantially in the future), the complexity of MNM value chains and life cycles, the accompanying possible changes in material properties over time and in contact with various environmental and organismal milieus, and the difficulties to obtain proper exposure data and to consider the proper dose metric. This article discusses these challenges and also critically overviews the current state of the art regarding MNM RA approaches. Copyright © 2016 Elsevier Inc. All rights reserved.

    Science.gov (United States)

    Whiting, Demian

    2007-01-01

    The author outlines a number of reasons why morally inappropriate attitudes may give rise to concerns about fitness to practise. He argues that inappropriate attitudes may raise such concerns because they can lead to harmful behaviours (such as a failure to give proper care or treatment), and because they are often themselves harmful (both because of the offence that they can cause and because of the unhealthy pall that they may cast over relations between healthcare practitioners and patients). He also outlines some of the challenges that the cultivation and assessment of attitudes in students raise for medical educators and some of the ways in which those challenges may be approached and possibly overcome.

    2013-10-01

    Full Text Available The Ministry of Education in Thailand is currently distributing tablets to all first year primary (Prathom 1 school children across the country as part of the government’s “One Tablet Per Child” (OTPC project to improve education. Early indications suggest that there are many unexplored issues in designing and implementing tablet activities for such a large and varied group of students and so far there is a lack of evaluation on the effectiveness of the tablet activities. In this article, the authors propose four challenges for the improving Thailand’s OTPC project, consisting of: developing contextualised content, ensuring usability, providing teacher support, and assessing learning outcomes. A case study on developing science activities for first year primary school children on the OTPC devices is the basis for presenting possible solutions to the four challenges. In presenting a solution to the challenge of providing teacher support, an architecture is described for collecting data from student interactions with the tablet in order to analysis the current progress of students while in a live classroom setting. From tests in three local Thai schools, the authors evaluate the case study from both student and teacher perspectives. In concluding the paper, a framework for guiding mobile learning innovation is utilised to review the qualities and shortcomings of the case study.

    Several challenges make it difficult to simultaneously investigate central and autonomous nervous system correlates of conditioned stimulus (CS) processing in classical conditioning paradigms. Such challenges include, for example, the discrepant requirements of electroencephalography (EEG) and electrodermal activity (EDA) recordings with regard to multiple repetitions of conditions and sufficient trial duration. Here, we propose a MultiCS conditioning set-up, in which we increased the number of CSs, decreased the number of learning trials, and used trials of short and long durations for meeting requirements of simultaneous EEG-EDA recording in a differential aversive conditioning task. Forty-eight participants underwent MultiCS conditioning, in which four neutral faces (CS+) were paired four times each with aversive electric stimulation (unconditioned stimulus) during acquisition, while four different neutral faces (CS-) remained unpaired. When comparing after relative to before learning measurements, EEG revealed an enhanced centro-posterior positivity to CS+ vs. CS- during 368-600 ms, and subjective ratings indicated CS+ to be less pleasant and more arousing than CS-. Furthermore, changes in CS valence and arousal were strong enough to bias subjective ratings when faces of CS+/CS- identity were displayed with different emotional expression (happy, angry) in a post-experimental behavioral task. In contrast to a persistent neural and evaluative CS+/CS- differentiation that sustained multiple unreinforced CS presentations, electrodermal differentiation was rapidly extinguished. Current results suggest that MultiCS conditioning provides a promising paradigm for investigating pre-post-learning changes under minimal influences of extinction and overlearning of simple stimulus features. Our data also revealed methodological pitfalls, such as the possibility of occurring artifacts when combining different acquisition systems for central and peripheral

    Data about patients are available from diverse sources, including those routinely collected as individuals interact with service providers, and those provided directly by individuals through surveys. Linking these data can lead to a more complete picture about the individual, to inform either care decision making or research investigations. However, post-linkage, differences in data recording systems and formats present barriers to achieving these aims. This paper describes an approach to combine linked GP records with study observations, and reports initial challenges related to semantic and syntactic interoperability issues.

    Martinez, M N; Hunter, R P

    2010-10-01

    Despite the pharmacological and statistical advances that have occurred since the early days of bioequivalence assessments, there remain many unresolved issues associated with the bioequivalence evaluation of human and veterinary pharmaceuticals. While many of these issues are common to both human and veterinary medicine, there are also challenges specific to veterinary drug products. Examples of complex problems that remain to be resolved include the assessment of drugs associated with complex kinetics (e.g., sustained release formulations that produce multiple peaks), the evaluation of intramammary formulations, uncertainty associated with conditions under which specific enantiomers of metabolites need to be factored into the bioequivalence evaluation, the study design for products and active pharmaceutical ingredients that exhibit highly variable kinetics, equivalence of biomass products, methods for evaluating topical formulations or formulations with very long duration of release, the evaluation of products where destructive sampling is necessary (e.g., aquaculture products), and the evaluation of bioequivalence for Type A medicated articles. This manuscript highlights many of the unresolved challenges currently impacting the evaluation of product bioequivalence in veterinary medicine, and provides a summary of the associated scientific complexities with each of these issues. © 2010 Blackwell Publishing Ltd.

    Full Text Available Vee P Prasher, Hassan Mahmood, Madhumanti Mitra Birmingham Learning Disability Service, Birmingham Community Healthcare NHS Foundation Trust, Birmingham, UK Abstract: Dementia in Alzheimer’s disease (DAD is more common in adults with Down syndrome (DS, with characteristically an earlier onset. The treatment of DAD is not too dissimilar in the general population and in people with intellectual disabilities. However, the underlying intellectual disability can make the management of DAD more challenging in older adults with DS. This literature review aimed to look at the management of DAD in people with DS. The management of dementia is holistic. This includes treating reversible factors, aiming to slow the cognitive decline, psychological therapies, ensuring that the environment is appropriate, and use of psychotropic medication when necessary to manage behavioral problems, psychotic symptoms, depressive symptoms, and sleep difficulty. Antidementia medications have a role to play but remain limited. The management of DAD in the DS population can be at times challenging, but good clinical practice should involve accurate diagnosis of dementia, treating any reversible additional factors, consideration of psychological and behavioral management, use of antidementia medication, and a multidisciplinary team approach.

  1. A Cross-Cultural Perspective on Challenges Facing Comparative Cancer Survivorship Research

    Directory of Open Access Journals (Sweden)

    Astri Syse

    2011-01-01

    Full Text Available Cancer survivorship research includes the study of physical, psychosocial, and economic consequences of cancer diagnosis and treatment among pediatric and adult cancer survivors. Historically, the majority of cancer survivorship studies were from the United States, but survivorship issues are increasingly being addressed in other developed countries. Cross-cultural studies remain, however, scarce. The degree to which knowledge attained may or may not be transferred across cultures, countries, or regions is not known. Some important challenges for comparative research are therefore discussed in a cross-cultural perspective. Several substantive and methodological challenges that complicate the execution of cross-cultural cancer survivorship research are presented with examples and discussed to facilitate comparative research efforts in the establishment of new survivorship cohorts and in the planning and implementation of survivorship studies. Comparative research is one key to understanding the nature of cancer survivorship, distinguishing modifiable from nonmodifiable factors at individual, hospital, societal, and system levels and may thus guide appropriate interventions. Lastly, suggested future courses of action within the field of comparative cancer survivorship research are provided.

    Full Text Available This paper analyzes weaknesses faced by the carbon neutrality initiative proposed by the Costa Rican government due to metrics and highlights some of the technical improvements that will be required in order to achieve greater comparability, applicability and confidence from the results obtained. Technical gaps are found not only in the assessment of greenhouse gas emissions but when accounting for biogenic carbon capture and storage, where global reference values, usually those reported by the IPCC, are commonly used. We then make reference to problems associated with their use, mainly related to the uncertainty (accuracy and precision that results from any estimate. At the national level there is a lack of information for biomass and carbon for some ecosystems as well as few complete studies that consider all carbon pools at the ecosystem level. We give examples for some of the most studied species. Finally, we compare results using global reference values against those developed from local studies a the national level.

    This report identifies underlying economic and electricity market factors that have led to early retirements of U.S. operating nuclear power plants, assesses the Gap between operating revenues and operating costs for selected nuclear power plants, and discusses a range of actions that might be taken to stop early retirement of operating nuclear power plants. The Kewaunee and Vermont Yankee nuclear power plants were retired early for economic and financial reasons. Early retirement has been announced or proposed for Clinton and Quad Cities in Illinois, Fitzpatrick and Ginna in New York, Fort Calhoun in Nebraska. Other nuclear power plants, including Palisades, Davis-Besse, Prairie Island, and Three Mile Island Unit 1, have been identified as facing financial stress that might lead to early retirement. The early retirement of operating nuclear power plants will mean the loss of a large amount of zero-emission electricity, inconsistent with the goal of reducing carbon emissions in the electricity sector. This report provides a high-level view of the major factors driving early retirement: • The U.S. market and private ownership approach to the electricity sector; • Low electricity market prices resulting from low natural gas prices, low demand growth, increased penetration of renewable generation, and negative electricity market prices; and • No compensation to nuclear power plants for public benefits including zero-emission electricity.

    The design of the Gelugor Mainline pipeline in Malaysia faced several obstacles of major importance. The Gelugor Mainline is part of the Peninsular Gas Utilization Project - Stage III. This NPS 24 gas pipeline is approximately 7 km in length and runs from Tenaga National Berhad (TNB) Prai Power Plant of the main line to TNB Gelugor Power Plant on Penang Island. Operating at high pressure, the route runs through complex terrain with varied seabed lithology with depth up to 16 m. It will cross active shipping lanes, zones of live electrical cables, an extensive system of submarine pipeline, mudbank and areas susceptible to mass gravity flows. The development of a Light Rapid Transportation system and the proposed development of a Vision City are both within a few meters of the route of the pipeline. In addition, the pipeline traverses an environmentally sensitive region which includes the rearing of caged fishing activities. A risk assessment study was performed to determine the mitigation actions required and appropriate evasion procedures. The busy shipping strait became the site of a detailed survey of its activities. The different phases of the design process were explained in the presentation as well as an outline of the techniques employed in the design of the pipeline. 7 refs., 2 tabs., 6 figs.

    The purposes of this article are: (a) to describe and analyze the accrual and retention patterns in a longitudinal randomized clinical trial with prostate cancer patients and their partners, and (b) to discuss strategies that were used to overcome challenges in conducting this family-based study. Initially, 429 dyads were referred to the study. Of these, 166 were not enrolled due to refusal (n = 120) or ineligibility (n = 46), 21 of whom did not meet one or more of the inclusion criteria, and 25 of whom could not be reached within the 2-month window of eligibility. Of the 383 eligible dyads, 263 dyads were enrolled (enrollment rate of 68.7%). Accrual and retention patterns differed by research site, referral procedures, and phase of prostate cancer. The retention rate was very good with the majority of dyads (n = 218) completing all three follow-up assessments at 4, 8, and 12 months (82.9%).

  6. Cyber crime: can a standard risk analysis help in the challenges facing business continuity managers?

    Science.gov (United States)

    Vande Putte, Danny; Verhelst, Marc

    Risk management has never been easy. Finding efficient mitigating measures is not always straightforward. Finding measures for cyber crime, however, is a really huge challenge because cyber threats are changing all the time. As the sophistication of these threats is growing, their impact increases. Moreover, society and its economy have become increasingly dependent on information and communication technologies. Standard risk analysis methodologies will help to score the cyber risk and to place it in the risk tolerance matrix. This will allow business continuity managers to figure out if there is still a gap with the maximum tolerable outage for time-critical business processes and if extra business continuity measures are necessary to fill the gap.

    The purpose of this study was to describe child health centre (CHC) nurses' views of managing parental groups during early childhood. All 311 CHC nurses working within the Swedish CHC system in one county were asked to complete a web-based questionnaire. Findings showed that although the CHC nurses were experienced, several found group leadership challenging and difficult. The need for specialized groups for young parents, single parents and parents whose first language was not Swedish was identified by 57% of the nurses. The CHC nurses found the participation of fathers in their parental groups to be low (an estimate of 10-20%), and 30% of the nurses made special efforts to make the fathers participate. Education in group dynamics and group leadership can strengthen CHC nurses in managing parental groups. It is recommended that specialized parental groups are organized by a few family centres so CHC nurses can develop their skill in managing such groups.

  8. Perception Challenges Faced by Al-Qaeda on the Battlefield of Influence Warfare

    2012-03-01

    Full Text Available Many kinds of entities—including terrorists and insurgents—seek to influence perceptions and behavior among various target audiences, and have become increasingly reliant on the Internet in their efforts, incorporating social media, blogging, public video sharing and other online tools. This article is focused on the ideological messages that terrorist groups use to convey with these tools. Drawing from a study of Al-Qaeda, this discussion illustrates how ideologies of violence have certain vulnerabilities that can be exploited in order to degrade a terrorist group’s ability to achieve its objectives. While crafting and disseminating counter-narratives can be a critical part of a counterterrorism strategy, it is also important to identify ways in which terrorists undermine their own central narratives and exacerbate pre-existing “influence warfare” challenges

    Anthropogenic impacts are endangering many long-lived species and lineages, possibly leading to a disproportionate loss of existing evolutionary history (EH) in the future. However, surprisingly little is known about the loss of EH during major extinctions in the geological past, and thus we do not know whether human impacts are pruning the tree of life in a manner that is unique in the history of life. A major impediment to comparing the loss of EH during past and current extinctions is the conceptual difference in how ages are estimated from paleontological data versus molecular phylogenies. In the former case the age of a taxon is its entire stratigraphic range, regardless of how many daughter taxa it may have produced; for the latter it is the time to the most recent common ancestor shared with another extant taxon. To explore this issue, we use simulations to understand how the loss of EH is manifested in the two data types. We also present empirical analyses of the marine bivalve clade Pectinidae (scallops) during a major Plio-Pleistocene extinction in California that involved a preferential loss of younger species. Overall, our results show that the conceptual difference in how ages are estimated from the stratigraphic record versus molecular phylogenies does not preclude comparisons of age selectivities of past and present extinctions. Such comparisons not only provide fundamental insights into the nature of the extinction process but should also help improve evolutionarily informed models of conservation prioritization.

    The farm animal veterinary profession in the UK has faced a number of challenges in recent decades related to the withdrawal of government funding and a contraction of the agricultural sector. They have come under pressure to respond by developing skills and focusing on disease prevention advisory services. However, this puts veterinarians in competition with other providers of these services, and moves in this direction have only been partial. Failure to respond to these challenges puts the veterinary profession at risk of de-professionalisation-a loss of their monopoly over knowledge, an erosion of client beliefs in their service ethos and a loss of work autonomy. This paper explores how farm animal veterinarians in England perceive these challenges and are responding to them. Semi-structured qualitative interviews were carried out with 28 veterinarians from Royal College of Veterinary Surgeon farm accredited practices. Veterinarians were chosen from high, medium and low density cattle farming regions. Interviews were recorded, transcribed and themes identified through the constant comparison method. The majority of respondents recognised the challenges facing the veterinary profession. Most believed their role had changed, moving towards that of a disease prevention adviser who was part of the farm management team. In terms of maintaining and redefining their professional status, farm animal veterinarians do have a defined body of knowledge and the ability to develop trusting relationships with clients, which enhances their competitiveness. However, while they recognise the changes and challenges, moves towards a disease prevention advisory model have only been partial. There seem to be little effort towards using Farm accreditation status or other strategies to promote their services. They do not appear to be finding effective strategies for putting their knowledge on disease prevention into practice. Disease prevention appears to be delivered on farm on an ad

    Along the United States–Mexican border, the health of communities, economies, and ecosystems is inextricably intertwined with the availability and quality of water, but effective water management in the Borderlands is complicated. Water users compete for resources, and their needs are increasing. Managers are faced with issues such as finding a balance between agriculture and rapidly growing cities or maintaining public supplies while ensuring sufficient resources for aquatic ecosystems. In addition to human factors, the dry climate of the Borderlands, as compared to more temperate regions, also increases the challenge of balancing water supplies between humans and ecosystems. Warmer, drier, and more variable conditions across the southwestern United States—the projected results of climate change (Seager and others, 2007)—would further stress water supplies.

    Along the nearly 3,200 kilometers (almost 2,000 miles) of the United States–Mexican border, we are witnessing the expression of the challenges of the 21st century. The Borderlands have become a microcosm for the entire United States and Mexico; the issues faced in that region are felt throughout both nations—water availability and quality, ecosystem health, natural resource needs, safety from natural hazards, and human socioeconomic well-being. If these issues were not challenging enough, we now recognize that the difficulties of addressing them are exacerbated by the onset of climate change, and as we come to better understand the complexities of the components of these challenge themes, we discover that each part is inextricably intertwined with other overarching issues. Further, because we are a creative and progressive society, we all seek to understand and appreciate the natural environments associated with the Borderlands while at the same time benefitting from the region’s many social and economic values. It is little wonder that we as a society find it increasingly difficult to ask the right questions, much less find suitable answers to the questions we do ask. For the many scientists who have worked in the Borderlands and contributed to the preceding chapters, this circular is a way to describe to the two nations of the region the capabilities the U.S. Geological Survey can provide to assist in that quest for knowledge and understanding in preparation for the future.

    Detect plant responses to environmental changes across tropical systems, especially in the Southern Hemisphere, is an important question in the global agenda, since few studies have addressed trends related to global warming. Traditional on-the-ground direct, manned phenological observations preclude large areas of study, are laborious and time consuming and restricts frequency of observations to large time-intervals (usually monthly). Near-surface remote phenology using digital cameras or phenocams set up at the top of towers have reduced the temporal and labor constraints of on-the-ground human observations, and eliminates the uncertainty of cloud cover, enhancing the resolution of information at individual tree, species, and community scales. Phenocams have reduced considerably manpower, since images are taken sequentially at reduced time-scales. Furthermore, Phenocams have proven to be an important tool for monitoring several species and ecosystems, accurately accessing leaf changes daily or several times a day and the relation to climate drivers but it is still area-limited. Here we propose to apply new technologies to enhance the capabilities near-surface remote phenological observations by integrating at time and space to detect changes on vegetation phenology at various scales, from leaves to ecosystems. Our studies have been carried out in the rupestrian grassland (campos rupestres) a rare, unique Brazilian mountain ecosystem, distinguished by a highly species rich, heterogeneous herbaceous/shrub vegetation and high number of endemic species. We discuss how the combination of cutting-edge technologies collected and framed within a e-science research project has been used to increase our observational capabilities in space by integrating phenology to cutting-edge technologies of environmental and phenology monitoring systems, based on the combination of two near-surface remote phenology monitoring systems: digital and hyperspectral sensors at three scales

    In order for the U.S. Geological Survey (USGS) to respond to evolving national and global priorities, it must periodically reflect on, and optimize, its strategic directions. This report is the first comprehensive science strategy since the early 1990s to examine critically major USGS science goals and priorities. The development of this science strategy comes at a time of global trends and rapidly evolving societal needs that pose important natural-science challenges. The emergence of a global economy affects the demand for all resources. The last decade has witnessed the emergence of a new model for managing Federal lands-ecosystem-based management. The U.S. Climate Change Science Program predicts that the next few decades will see rapid changes in the Nation's and the Earth's environment. Finally, the natural environment continues to pose risks to society in the form of volcanoes, earthquakes, wildland fires, floods, droughts, invasive species, variable and changing climate, and natural and anthropogenic toxins, as well as animal-borne diseases that affect humans. The use of, and competition for, natural resources on the global scale, and natural threats to those resources, has the potential to impact the Nation's ability to sustain its economy, national security, quality of life, and natural environment. Responding to these national priorities and global trends requires a science strategy that not only builds on existing USGS strengths and partnerships but also demands the innovation made possible by integrating the full breadth and depth of USGS capabilities. The USGS chooses to go forward in the science directions proposed here because the societal issues addressed by these science directions represent major challenges for the Nation's future and for the stewards of Federal lands, both onshore and offshore. The six science directions proposed in this science strategy are listed as follows. The ecosystems strategy is listed first because it has a dual nature

    Recent and rapidly evolving progress on high-throughput measurement techniques and computational performance has led to the emergence of new disciplines, such as systems medicine and translational systems biology. At the core of these disciplines lies the desire to produce multiscale models: mathematical models that integrate multiple scales of biological organization, ranging from molecular, cellular and tissue models to organ, whole-organism and population scale models. Using such models, hypotheses can systematically be tested. In this review, we present state-of-the-art multiscale modelling of bacterial and fungal infections, considering both the pathogen and host as well as their interaction. Multiscale modelling of the interactions of bacteria, especially Mycobacterium tuberculosis, with the human host is quite advanced. In contrast, models for fungal infections are still in their infancy, in particular regarding infections with the most important human pathogenic fungi, Candida albicans and Aspergillus fumigatus. We reflect on the current availability of computational approaches for multiscale modelling of host-pathogen interactions and point out current challenges. Finally, we provide an outlook for future requirements of multiscale modelling. © The Author 2016. Published by Oxford University Press.

    Therapeutic monoclonal antibodies have become an important class of modern medicines.The established technologies for therapeutic antibody discovery such as humanization of mouse antibodies,phage display of human antibody libraries and transgenic animals harboring human IgG genes have been practiced successfully so far,and many incremental improvements are being made constantly.These methodologies are responsible for currently marketed therapeutic antibodies and for the biopharma industry pipeline which are concentrated on only a few dozen targets.A key challenge for wider application of biotherapeutic approaches is the paucity of truly validated targets for biotherapeutic intervention.The efforts to expand the target space include taking the pathway approach to study the disease correlation.Since many new targets are multi-spanning and multimeric membrane proteins there is a need to develop more effective methods to generate antibodies against these difficult targets.The pharmaceutical properties of therapeutic antibodies are an active area for study concentrating on biophysical characteristics such as thermal stability and aggregation propensity.The immunogenicity of biotherapeutics in humans is a very complex issue and there are no truly predictive animal models to rely on.The in silico and T-cell response approaches identify the potential for immunogenicity;however,one needs contingency plans for emergence of antiproduct antibody response for clinical trials.

    The discourse of leaderism in health care has been a subject of much academic and practical debate. Recently, distributed leadership (DL) has been adopted as a key strand of policy in the UK National Health Service (NHS). However, there is some confusion over the meaning of DL and uncertainty over its application to clinical and non-clinical staff. This article examines the potential for DL in the NHS by drawing on qualitative data from three co-located health-care organisations that embraced DL as part of their organisational strategy. Recent theorising positions DL as a hybrid model combining focused and dispersed leadership; however, our data raise important challenges for policymakers and senior managers who are implementing such a leadership policy. We show that there are three distinct forms of disconnect and that these pose a significant problem for DL. However, we argue that instead of these disconnects posing a significant problem for the discourse of leaderism, they enable a fantasy of leadership that draws on and supports the discourse.

    In the 21st Conference of the Parties held in Paris in December 2015, China pledged to peak its carbon emissions and increase non-fossil energy to 20% by 2030 or earlier. Expanding renewable capacity, especially wind power, is a central strategy to achieve these climate goals. Despite greater capacity for wind installation in China compared to the US (145.1 versus 75.0 GW), less wind electricity is generated in China (186.3 versus 190.9 TWh). Here, we quantify the relative importance of the key factors accounting for the unsatisfactory performance of Chinese wind farms. Different from the results in earlier qualitative studies, we find that the difference in wind resources explains only a small fraction of the present China-US difference in wind power output (-17.9% in 2012); the curtailment of wind power, differences in turbine quality, and delayed connection to the grid are identified as the three primary factors (respectively -49.3%, -50.2%, and -50.3% in 2012). Improvements in both technology choices and the policy environment are critical in addressing these challenges.

    Advances in medicine have increased the life expectancy resulting in an increase in the geriatric population all over the world, and their proportion will only continue to rise in the coming years. It is known that the elderly bear a significant burden of morbidity, which is why health systems globally spearheaded by the WHO are waking up to the need for better geriatric health services. This includes India, whose health system continues to grapple with the health challenges of communicable and noncommunicable diseases. This article enumerates the various government policies and programs, constitutional and legal provisions available for the care of the elderly, and concludes that they are grossly inadequate to deal with the various physical, psychological, and emotional needs of the aging population. Mainstreaming of geriatric health to address the health needs of the elderly at all levels of health care, both in the public and the private sectors, giving due importance to multidimensional rehabilitative services and terminal care, involving NGOs and voluntary organizations, and stepping up social security in old age are the recommended measures for improving geriatric health in India.

  5. Networked Social Enterprises: A New Model of Community Schooling for Disadvantaged Neighborhoods Facing Challenging Times

    Full Text Available Community schools have long been accepted as an institutional mechanism for intervening in the relationship between poverty, poor educational outcomes, and limited life chances. At a time when public services are being retracted, and disadvantaged places are being increasingly left to struggle, community schools are poised to become more important in offering a response to the needs of children, families, and communities in these places. Yet, despite their apparent promise, community schools remain badly under-conceptualized. As an international field, research on community schooling has rarely articulated or questioned how—by providing additional learning and leisure opportunities and personal and social supports—community schools might create a viable intervention in the relationship between poverty and poor outcomes. This paper explicitly addresses this significant challenge. Conceptualizing empirical findings emerging from a research-practice partnership, it identifies the core features of a new institutional design for community schools which can help to clarify their potential contribution to addressing disadvantage. Marking a considerable shift from a traditional design of simply adding new services to the school day, it argues that community schools will need to operate as social enterprises with networked governance arrangements, and to develop strategies which engage with children’s social ecologies, and are risk-reducing and resilience-building within these. This, in turn, sets a new agenda for significantly advancing the field of community schooling by further defining—conceptually and empirically—the core elements of a new institutional design as identified here.

    Full Text Available Despite a record-breaking 14.5 per cent increase in world merchandise exports, the effects of the financial crisis and global recession are still hampering faster economic recovery. Relatively high oil prices combined with persistent unemployment and measures designed to reduce budget deficits have undermined short-term growth prospects. While South–South trade continues to explode, trade imbalances – i.e. the gap between exports and imports – widened in 2010 compared to 2009 (though smaller than pre-crisis levels. Meanwhile, trade negotiations under the Doha Round have reached an impasse, generating uncertainties about the future of the World Trade Organization (WTO as a negotiating forum. Under these circumstances, should the system rethink its decision-making process founded upon the predominance of member states, the principle of consensus and the notion of single undertaking, as some critics have suggested? And, if so, how could such a reform agenda be initiated at the WTO? Moreover, beyond the negotiating function of the WTO, the paralysis of the system also raises urgent questions about the ability of the system to respond to pressing challenges of our times, such as trade and climate change, or food security and price volatility.

    This paper is in response to an invitation to address the topic of advocacy and diversity from the perspective of past and present transcultural nursing. With origins in nursing, with its philosophy of active intervention, and in anthropology, where relativism proposes merit in diverse (including non-interventive) approaches to health and illness, transcultural nursing grapples with potential epistemological conflict as it helps shape health care in highly industrialized, multicultural societies and even more varied global contexts. As a developing subdiscipline, transcultural nursing continuously reexamines dialectical relationships between change and preservation and between health care needs and the risk of imposition. Whereas advocacy is viewed as a moral imperative in nursing, diversity (which can be used to argue against acknowledgement of differences and to promote the pretense that everything is the same for everyone) remains better developed conceptually than operationally, while universality too often falls prey to misuse as an argument against acknowledgement of diversity. Within a framework constructed from the juxtaposition of advocacy with diversity/universality (Leininger, 1988c, 1991), this article appraises the accomplishments and challenges of transcultural nursing as it moves into its second quarter century. It is proposed that the future of transcultural nursing should emphasize development of realistic nursing roles that include a confluence of advocacy and diversity/universality and negotiation of responsible social conceptualizations of cultural issues such as "race" and diversity.

    Much progress has been made in understanding the pathophysiology and treatment of atypical hemolytic uremic syndrome (aHUS). Plasma therapy is the mainstay of treatment for aHUS. The availability of the first effective anti-complement therapeutic agent, eculizumab, has dramatically changed the outlook of this disease. However, its use in clinical practice raises important questions, such as who should receive the drug, when to start such therapy, and is it safe to stop treatment once the disease is controlled. We describe here for the 1st time in India, use of eculizumab in a 12-year-old boy with aHUS. We also describe in this report challenges faced in procuring the drug, and an ideal, evidence-based method of treating aHUS in children. PMID:28182046

    The Tanzania informal sector is growing fast, with precarious working conditions and particular hazards for women and children in agriculture. Hazardous agricultural chemicals including pesticides are mostly imported and have been used for many years. Despite the role played by pesticides in food security and vector control, these chemicals are responsible for acute and chronic illnesses among communities. The availability of obsolete persistent organic pesticides on the open market indicates existence of an inadequate regulatory system. People who get injured or ill in the agriculture sector in Tanzania receive health services in primary health care facilities where professionals have little or no knowledge of pesticides. We are presenting the pesticide health and safety challenges faced by small-scale farmers who fall in the informal sector. Achievements that have been made by the government and other players to reduce and prevent pesticide exposures and poisoning are also outlined.

    Full Text Available Background Thalassemia is considered an important public health problem worldwide, especially in developing and poor countries. Although several advanced techniques have been developed for prevention of thalassemia in the recent years, many adolescents and youths are still living with this disease. Independence from parents, decisions about high-risk behaviors, uncovering the identity, and adapting to mental and physical effects of the disease occur together in adolescents. Objectives This study was conducted to explore challenges of self-management empowerment in adolescents and youths with major thalassemia. Materials and Methods This was a descriptive-exploratory study. The study population consisted of adolescents and youths with major thalassemia who had medical records in the Bushehr Thalassemia Center, affiliated with Bushehr University of Medical Sciences. The study samples were purposively selected. Demographic information questionnaire and empowerment questionnaire were used to collect data from the semistructured interview. We analyzed qualitative data by content analysis method and quantitative data by descriptive (mean, standard deviation and analytical (Student's t-test, ANOVA and Pearson’s correlation coefficient statistical methods, using the statistical software SPSS 18. Results In qualitative part of the study, data from semistructured in-depth interviews with 15 participants were coded and summarized in five themes including: 1 awareness of personal changes; 2 need for adaptation; 3 maintaining independence and self-management; 4 uncovering the identity and role playing; and 5 sense of control and satisfaction. Results of the quantitative part showed that the overall score of participants on empowerment was 92.46 of 149 scores, which showed a moderate situation in the empowerment of these individuals. In addition, the empowerment score showed no statistically significant correlation with demographic characteristics

    Full Text Available With broad distributions, diadromous fishes can be exposed to multiple threats at different stages of development. For the primarily catadromous eels of the family Anguillidae, there is growing international concern for the population abundance and escapement trends of some of these species and yet incomplete knowledge of their remarkable life-histories hampers management and conservation. Anguillids experience a suite of pressures that include habitat loss/modification, migration barriers, pollution, parasitism, exploitation, and fluctuating oceanic conditions that likely have synergistic and regionally variable impacts, even within species. In beginning to redress this rather fragmented picture, we evaluated the extinction risk of these species using the IUCN Red List of Threatened Species Categories and Criteria to infer population-wide trends from catch and monitoring data. Here we consolidate and build upon these species assessments by presenting an overview of the current state of global eel data and conservation, categorising the knowledge gaps and geographic regions where resources are needed and discussing future recommendations to improve our understanding of anguillids. We find stark disparity between the quality and length of data available to assess population trends and conservation priorities in temperate and tropical anguillids. Of the 13 species assessed, four were listed as ‘Threatened’ (Vulnerable, Endangered or Critically Endangered; four were Near Threatened, three were Data Deficient and two were deemed Least Concern. Comparing with other diadromous species, we examine the multiple threats that impact eels during their different life-history stages, highlighting the challenges of applying the Red List Categories and Criteria to geographically-expansive, catadromous and panmictic groups of species.

    2013-01-01

    Historically, international borders were located far from the major political and economic capitals of their countries and rarely received adequate planning or infrastructure development. Today, as a result of global economics and increased movement of goods between nations, border regions play a much greater role in commerce, tourism, and transportation. For example, Mexico is the second largest destination for United States exports (Woodrow Wilson Center Mexico Institute, 2009). The rapid population and economic growth along the United States–Mexican border, undocumented human border crossings, and the unique natural diversity of resources in the Borderlands present challenges for border security and environmental protection. Assessing risks and implementing sustainable growth policies to protect the environment and quality of life greatly increase in complexity when the issues cross an international border, where social services, environmental regulations, lifestyles, and cultural beliefs are unique for each country. Shared airsheds, water and biological resources, national security issues, and disaster management needs require an integrated binational approach to assess risks and develop binational management strategies.

    Oman contains diverse and abundant reef coral communities that extend along a coast that borders three environmentally distinct water bodies, with corals existing under unique and often stressful environmental conditions. In recent years Oman's reefs have undergone considerable change due to recurrent predatory starfish outbreaks, cyclone damage, harmful algal blooms, and other stressors. In this review we summarize current knowledge of the biology and status of corals in Oman, particularly in light of recent stressors and projected future threats, and examine current reef management practices. Oman's coral communities occur in marginal environmental conditions for reefs, and hence are quite vulnerable to anthropogenic effects. We recommend a focus on developing conservation-oriented coral research to guide proactive management and expansion of the number and size of designated protected areas in Oman, particularly those associated with critical coral habitat.

  16. Challenges Women with Disability Face in Accessing and Using Maternal Healthcare Services in Ghana: A Qualitative Study.

    Directory of Open Access Journals (Sweden)

    John Kuumuori Ganle

    Full Text Available While a number of studies have examined the factors affecting accessibility to and utilisation of healthcare services by persons with disability in general, there is little evidence about disabled women's access to maternal health services in low-income countries and few studies consult disabled women themselves to understand their experience of care and the challenges they face in accessing skilled maternal health services. The objective of this paper is to explore the challenges women with disabilities encounter in accessing and using institutional maternal healthcare services in Ghana.A qualitative study was conducted in 27 rural and urban communities in the Bosomtwe and Central Gonja districts of Ghana with a total of 72 purposively sampled women with different physical, visual, and hearing impairments who were either lactating or pregnant at the time of this research. Semi-structured in-depth interviews were used to gather data. Attride-Stirling's thematic network framework was used to analyse the data. Findings suggest that although women with disability do want to receive institutional maternal healthcare, their disability often made it difficult for such women to travel to access skilled care, as well as gain access to unfriendly physical health infrastructure. Other related access challenges include: healthcare providers' insensitivity and lack of knowledge about the maternity care needs of women with disability, negative attitudes of service providers, the perception from able-bodied persons that women with disability should be asexual, and health information that lacks specificity in terms of addressing the special maternity care needs of women with disability.Maternal healthcare services that are designed to address the needs of able-bodied women might lack the flexibility and responsiveness to meet the special maternity care needs of women with disability.

    Journalists who cover scientific research, including chemistry research, have an obligation to report on alleged cases of research misconduct when knowledge of these surface. New Government definitions of research misconduct, beginning in the late 1990s with the Clinton Administration, have helped scientists, policymakers, as well as journalists sort out and make sense of alleged research misconduct. Journalistic reporting on research misconduct includes many challenges: gathering information from sources who are intimidated or afraid to speak, strict adherence to journalist ethics that take on a new dimension when careers, reputations, and research funding are at stake; efforts by government and institutional bureaucrats to dampen or thwart legitimate news coverage. The Internet, blogging, and social media have added still more complexity and ethical quandaries to this blend. The author, News Editor of Chemical & Engineering News published by the American Chemical Society, provides examples from his own career and that of colleagues. He suggests that an enhanced spirit of understanding and cooperation between journalists and members of the scientific community can lead to avenues of open discussion of research misconduct--discussions that might prevent and mitigate the very real damage caused by bad actors in science who betray themselves, their peers, and the body of modern day scientific knowledge when they make the decision to march into the darkness of dishonesty, plagiarism, or falsification.

    2010-01-01

    Full Text Available A recent survey by Meyer (2009 on the need for the training of general library workers revealed that employers in library services are often not aware of the conditions affecting the ability of library and information science (LIS educators at South African tertiary institutions to deliver ‘work ready’ general workers to the LIS industry. Simultaneously, LIS educators are not aware of the extent to which changes to learning programmes can affect the appointment and promotions of library staff in practice. The objectives of the study were to determine the need for a formal learning programme for general library workers and how existing study material can be adapted to develop a formal learning programme suitable for general library workers countrywide. Data was collected by means of a self-administered questionnaire directed at supervisory staff of provincial and municipal libraries in South Africa, interviews with supervisors, and consultation of relevant internal documentation on job descriptions and legislation. The findings revealed that there is a definite need for training general library workers, whether formally or informally. This article, the first of two parts, considers the challenges facing LIS educators of which employers in the LIS industry are seldom aware of. The discussion is based on a literature study regarding training of general library workers in South Africa, as well as personal experience of the impact of various conditions on the relevant learning programmes of the Department of Information Science, University of South Africa before and after merging with the former Technikon SA. It considers the implementation of legislation and policies with regard to LIS training and how LIS educators, involved in open distance learning (ODL cope with the specific challenges for delivering ‘work ready’ general library workers.

    Difficulties faced by visually disabled people when using medicines, self-adopted coping strategies, and medicine-related mishaps have been under-explored locally and internationally. The objective of this study was to gain insight regarding this long-neglected issue. A descriptive cross-sectional study, using an interviewer administered questionnaire on 63 visually disabled adults was carried out at a vocational training centre and a school for visually disabled students in Sri Lanka. Among 63 participants, 71% wanted to be independent in medicine use and 79% in spite of difficulties had self-administered medicines. They had difficulty in locating medicines (25.39%), identifying medicines and medicine containers (17.46%), and administering liquid medications (25.39%). These difficulties led to inaccurate dosing (14.28%), missed doses (39.68%), and discontinuation of treatment prematurely (28.57%). Self-adopted coping strategies to overcome these difficulties included using different sized and shaped containers, tying medicines to the attire, and dipping their finger into a measuring cup while measuring liquid medicines. Mishaps related to medicines such as taking vinegar instead of gripe mixture and, putting ear drops into eyes were disclosed. There were many challenges for visually disabled people in taking medicines and some self-adopted coping strategies were inadequate to overcome these.

    Efforts to achieve effective and meaningful patient and public involvement (PPI) in healthcare have existed for nearly a century, albeit with limited success. This brief commentary discusses a recent paper by Carter and Martin exploring the "Challenges Facing Healthwatch, a New Consumer Champion in England," and places these challenges in the context of the broader struggle to give a voice to healthcare consumers and citizens. With an overview of what can go right and-perhaps more importantly-what can go wrong, the question remains: will Healthwatch-and other PPI efforts in healthcare-represent the voice of consumers or citizens and will it matter?

    Background Human immunodeficiency virus (HIV) remains a global public health problem. Sub-Saharan Africa is the region most affected by HIV/AIDS in the world. Globally, and in Tanzania in particular, women are more affected by HIV/AIDS than men. Tanzania has been reported to be among the countries with the highest burden of intimate partner violence (IPV). This study explored the challenges facing women living with HIV/AIDS (LWHA) attending the care and treatment clinic (CTC) in Singida Regional Hospital in Tanzania. Design A qualitative study was performed in which data were collected through in-depth interviews with 35 women LWHA who also experienced IPV. Content analysis was used to analyse the data. Results The study findings showed that women LWHA experienced challenges from their male partners in the form of lack of fare to attend CTC, delayed attendance to CTC, verbal threats and intimidation, mistrust partner resulting in changed antiretroviral (ARV) dosing time. Also, systemic challenges such as malfunction of CD4 count testing apparatus contributed to mistrust from their male partners which led to IPV. Conclusion In this study, women LWHA experienced IPV challenges that resulted in poor adherence to ARV medication and CTC attendance, as well as insufficient time to collect ARV medication. It is recommended that the government address systemic challenges faced by women LWHA, introduce multiple approaches to address the needs of women LWHA experiencing IPV, and develop strong policies to prevent IPV against women in Tanzania, regardless of their HIV status.

    Bolsinger, V; Schmelcher, P

    2016-01-01

    Exploring the impact of dimensionality on the quantum dynamics of interacting bosons in traps including particle correlations is an interesting but challenging task. Due to the different participating length scales the modelling of the short-range interactions in three dimensions plays a special role. We review different approaches for the latter and elaborate that for multi-configurational computational strategies finite range potentials are adequate resulting in the need of large grids to resolve the relevant length scales. This results in computational challenges which include also the exponential scaling of complexity with the number of atoms. We show that the recently developed ab-initio Multi-Layer Multi-Configurational Time- Dependent Hartee method for Bosons (ML-MCTDHB) [J. Chem. Phys. 139, 134103 (2013)] can face both numerical challenges and present an efficient numerical implementation of ML-MCTDHB in three spatial dimensions, particularly suited to describe the quantum dynamics for elongated traps...

    2015-12-01

    Full Text Available Participation in tourism brings individuals, families and communities together, making it an important social inclusion strategy. Negative perceptions about persons with disabilities could make it difficult for them to access public places. Therefore, this study served to examine tourism challenges for persons with disabilities (PwDs in the Ashanti region of Ghana. A cross sectional study with quantitative data collection was conducted with PwDs. Structured questionnaires were administered to 120 PwDs using a convenience sampling technique. Descriptive statistics were explored using SPSS version 20. The study found that PwDs faced barriers to facilities and structures at tourist destinations. The barriers to tourism included lack of income, negative attitudes of the public and physical barriers such as a lack of adapted toilet facilities, tables and chairs, inaccessible routes for wheel chair users, inability to climb walkways and an absence of canopy walk-ways. The study supports the evidence of challenges faced by PwDs at tourism destinations. Redesigning and resourcing tourism facilities to be more PwD friendly could remove barriers faced by PwDs in tourism, creating greater social inclusion for this population.

    2016-03-01

    Full Text Available Transportation is a key to the economy and social welfare; it makes mobility more accessible and enhances the social and economic interactions. On the other hand, the increase of urban population, pollution and other negative impacts has directly affected the existing transportation system in Dar es Salaam City - Tanzania. As the transportation challenges cannot be overcome simultaneously due to the scarcity of financial resources, a decision support tool is needed to prioritize these challenges. In this study, a composite model of Vague Set Theory (VST and Analytical Hierarchy Process (AHP is applied to appraise the challenges. The Vague Analytical Hierarchy Process (VAHP uses opinions of experts collected from a survey questionnaire. The computational results reveal the ranking in descending order of the urban transportation challenges as poor traffic management, inadequacy of proper public transit service and inadequacy of road transport infrastructure. The results also depict that the VAHP model is a useful decision support tool for transport planners, transport policy makers and other industry stakeholders.

    This study explores the emotional challenges faced by staff working on a sex offender treatment programme for people with an intellectual disability. Semi-structured interviews were carried out with eight participants working on a treatment programme for sex offenders with an intellectual disability. Interviews were analysed using interpretative phenomenological analysis. Staff experienced a range of negative emotions that they dealt with in a variety of ways including through the use of humour and various emotional defences. Empathy was a challenging and complex issue with individuals taking a variety of positions. Staff awareness and understanding of the role of emotions in relation to their own well-being and in relation to therapeutic processes varied. Emotional intelligence was associated with greater therapeutic understanding. Recommendations are made in relation to personal and professional characteristics and need for clinical supervision to support staff well-being and the development of therapeutic competence and effectiveness. © 2012 Blackwell Publishing Ltd.

    Cervical cancer is a leading cause of death among women in Ethiopia, affecting them at a time of their life when they are critical to social and economic stability. This study was mainly focused on assessing different socioeconomic and cultural related factors that make women vulnerable to cervical cancer and challenges women face in the process of diagnosis and treatment. To achieve the objective of the study both qualitative and quantitative methods were utilized.198 participants were enrolled in a cross- sectional survey and 10 in-depth interviews were conducted with patients in Tikur Anbessa Hospital. A consecutive sampling method was used to select participants in the survey while purposive sampling was employed to select participants in the qualitative design. For the population covered in the study, poverty along with other socio-cultural practices such as early marriage, high parity and to certain extent polygamy were identified as factors that increased the vulnerability of women to cervical cancer. In addition, the study has uncovered several challenges faced by cervical cancer patients in the diagnosis and treatment process. Three types of challenges that include, health care based, psychological and economic were identified. System and practitioner delay were found as the main hurdles within the variable of health care related challenges. What's more, the psychological challenges identified included, fear of recurrence, negative social attitude and distress associated with the side effects from treatments such as fecal & urinary leakage. Furthermore, inability of bearing costs related to treatment and accommodation were cited as the main economic challenges. The study showed various socio-economic and cultural vulnerabilities that expose women to cervical cancer and the challenges encountered by cervical cancer patients after their diagnosis. Addressing this issue largely lies in strengthening primary and secondary preventive mechanisms, providing

    2010-03-01

    In a prisoner's dilemma, constructed narratives are used to demonstrate problems within individual rationality and decision-making. Performing artists can be seen as facing a type of prisoner's dilemma in their careers: they must practice repeated movements for long periods in order to improve, yet despite the short-term perception of gained artistic benefit, the long-term consequences may be playing-related musculoskeletal disorders and injury. To help avoid such an outcome, educators and health and wellness practitioners must function as negotiators, engaging in discussions of artistry as part of establishing credibility and encouraging behaviors that keep artists in efficient, healthy behaviors. By setting practice time limits that are considerate of the intensity of each specific task, performers can improve their performance on a daily basis and become more skilled at planning their future training.

  19. Phenotypic plasticity in the common garden snail: big guts and heavier mucus glands compete in snails faced with the dual challenge of poor diet and coarse substrate.

    Munn, Adam J; Treloar, Marguerite

    2016-12-26

    Phenotypic plasticity allows animals to manage environmental challenges. Studies aimed at quantifying plasticity often focus on one challenge, such as diet, and one organ system, such the gastrointestinal tract, but this approach may not adequately reflect how plasticity could buffer multiple challenges. Thus, we investigated the outcomes of a dual challenge experiment that fed land snails either a high-fibre (low quality) or a low-fibre (high quality) diet, and simultaneously exercised them daily over 1.2 m on either a smooth surface of polyvinyl chloride (PVC) or a rough sandpaper. By the end of 20 days, snails fed the poor quality diet had a longer crop and oesophagus and a heavier intestine and rectum than those offered a low-fibre diet. Additionally, high-fibre fed snails had a smaller spermoviduct and oviduct. When also exercised on sandpaper, high-fibre fed snails had a smaller digestive gland, a main energy store, than those exercised on PVC. All snails exercised on sandpaper had a heavier pedal mucus gland, used a loping gait and used less mucus than those on PVC plastic, but there was no difference in the average speed of snails on either surface, supporting the conclusion that loping is a mucus conserving gait. Notably, snails faced with both a diet and substrate challenge had a smaller kidney, which could directly effect fecundity. This demonstrates that our dual challenge approach has potential for evaluating the costs and limits of the plasticity necessary to fully appreciate the evolutionary significance of plasticity in snails and other species.

    Full Text Available Background: Shortages of Human Resources for Health (HRH in rural areas are often driven by poor working and living conditions, inadequate salaries and benefits, lack of training and career development opportunities amongst others. The South African government has adopted a human resource strategy for the health sector in 2011 aimed at addressing these challenges.Aim: This study reviews the challenges faced by health personnel against government strategies aimed at attracting and retaining health personnel in these underserved areas.Setting: The study was conducted in six primary health care service sites in the Hlabisa sub-district of Umkhanyakude, located in northern KwaZulu-Natal, South Africa.Methods: The study population comprised 25 health workers including 11 professional nurses, 4 staff nurses and 10 doctors (4 medical doctors, 3 foreign medical doctors and 3 doctors undertaking community service. Qualitative data were collected from semi-structured interviews and analysed using thematic analysis.Results: Government initiatives including the rural allowance, deployment of foreign medical doctors and the presence of health personnel undertaking their community service in rural areas are positively viewed by health personnel working in rural health facilities. However, poor living and working conditions, together with inadequate personal development opportunities, remain unresolved challenges. It is these challenges that will continue to dissuade experienced health personnel from remaining in these underserved areas.Conclusion: South Africa’s HRH strategy for the Health Sector 2012/13–2015/16 had highlighted the key challenges raised by respondents and identified strategies aimed at addressing these challenges. Implementation of these strategies is key to improving both living and working conditions, and providing health personnel with opportunities for further development will require inter-ministerial collaboration if the HRH 2030

    Natural hazards such as earthquakes, landslides and debris flows, wildfires, hurricanes, and intense storm-induced flash floods threaten communities to varying degrees all along the United States–Mexican border. The U.S. Geological Survey (USGS) collaborates with Federal, State, and local agencies to minimize the effects of natural hazards by providing timely, unbiased science information to emergency response officials, resource managers, and the public to help reduce property damage, injury, and loss of life. The USGS often mobilizes response efforts during and after a natural hazard event to provide technical and scientific counsel on recovery and response, and it has a long history of deploying emergency response teams to major disasters in both domestic and international locations. This chapter describes the challenges of natural hazards in the United States–Mexican border region and the capabilities of the USGS in the fields of hazard research, monitoring, and assessment, as well as preventative mitigation and post-disaster response.

  2. Idiotypes as immunogens: facing the challenge of inducing strong therapeutic immune responses against the variable region of immunoglobulins.

    Directory of Open Access Journals (Sweden)

    Alejandro eLopez-Requena

    2012-11-01

    Full Text Available Idiotype (Id-based immunotherapy has been exploited as cancer treatment option. Conceived as therapy for malignancies bearing idiotypic antigens, it has been also extended to solid tumours because of the capacity of anti-idiotypic antibodies to mimick Id-unrelated antigens. In both these two settings, efforts are being made to overcome the poor immune responsiveness often experienced when using self immunoglobulins as immunogens. Despite bearing a unique gene combination, and thus particular epitopes, it is normally difficult to stimulate the immune response against antibody variable regions. Different strategies are currently used to strengthen Id immunogenicity, such as concomitant use of immune-stimulating molecules, design of Id-containing immunogenic recombinant proteins, specific targeting of relevant immune cells and genetic immunization. This review focuses on the role of anti-Id vaccination in cancer management and on the current developments used to foster anti-idiotypic B- and T-cell responses.

    Self-regulatory efficacy (SRE) should influence persistence towards goals. Mothers attempting to exercise while managing work and young children (N = 49, M(age) = 35.69, M(children) = 1.88) were stratified into high or low concurrent SRE groups, then randomized to read a hypothetical scenario detailing numerous or minimal exercise barrier conditions. Consistent with self-efficacy theory, when exercise barriers were numerous, mothers with higher concurrent SRE demonstrated greater persistence towards exercise goals, and perceived concurrent management of exercise with their other valued goals as more positively challenging, than mothers with lower concurrent SRE.

    Airway remodeling (AR) is a prominent feature of asthma and other obstructive lung diseases that is minimally affected by current treatments. The goals of this Official American Thoracic Society (ATS) Research Statement are to discuss the scientific, technological, economic, and regulatory issues that deter progress of AR research and development of therapeutics targeting AR and to propose approaches and solutions to these specific problems. This Statement is not intended to provide clinical practice recommendations on any disease in which AR is observed and/or plays a role. An international multidisciplinary group from within academia, industry, and the National Institutes of Health, with expertise in multimodal approaches to the study of airway structure and function, pulmonary research and clinical practice in obstructive lung disease, and drug discovery platforms was invited to participate in one internet-based and one face-to-face meeting to address the above-stated goals. Although the majority of the analysis related to AR was in asthma, AR in other diseases was also discussed and considered in the recommendations. A literature search of PubMed was performed to support conclusions. The search was not a systematic review of the evidence. Multiple conceptual, logistical, economic, and regulatory deterrents were identified that limit the performance of AR research and impede accelerated, intensive development of AR-focused therapeutics. Complementary solutions that leverage expertise of academia and industry were proposed to address them. To date, numerous factors related to the intrinsic difficulty in performing AR research, and economic forces that are disincentives for the pursuit of AR treatments, have thwarted the ability to understand AR pathology and mechanisms and to address it clinically. This ATS Research Statement identifies potential solutions for each of these factors and emphasizes the importance of educating the global research community as to the

    The prediction of global climate change in response to both natural forces and human activity is one of the defining issues of our times. The unprecedented observational capacity of modern earth-orbiting satellites coupled with the development of robust computational representations (models) of the Earth’s weather and climate systems afford us the opportunity to observe and investigate how these systems work now, how they have worked in the past, and how they will work in the future when forced in specific ways. In the most recent report on global climate change by the Intergovernmental Panel on Climate Change (IPCC; Solomon and others, 2007), analyses using multiple climate models support recent observations that the Earth’s climate is changing in response to a combination of natural and human-induced causes. These changes will be significant in the United States–Mexican border region, where the process of climate change affects all of the Borderlands challenge themes discussed in the preceding chapters. The dual possibilities of both significantly-changed climate and increasing variability in climate make it challenging to take full measure of the potential effects because the Borderlands already experience a high degree of interannual variability and climatological extremes.

    Bryophytes are a group of early land plants, whose specific ecophysiological and biological features, including poikilohydry, sensitivity to moderately high temperature and high dispersal ability, make them ideal candidates for investigating the impact of climate changes. Employing a combined approach of species distribution modelling (SDM) and molecular phylogeography in the temperate moss Homalothecium sericeum, we explore the significance of the Mediterranean refugia, contrasting the southern and northern refugia hypotheses, determine the extent to which recolonization of previously glaciated areas has been facilitated by the high dispersal ability of the species and make predictions on the extent to which it will be impacted by ongoing climate change. The Mediterranean areas exhibit the highest nucleotidic diversities and host a mixture of ancestral, endemic and more recently derived haplotypes. Extra-Mediterranean areas exhibit low genetic diversities and Euro-Siberian populations display a significant signal of expansion that is identified to be of Euro-Siberian origin, pointing to the northern refugia hypothesis. The SDMs predict a global net increase in range size owing to ongoing climate change, but substantial range reductions in southern areas. Presence of a significant phylogeographical signal at different spatial scales suggests, however, that dispersal limitations might constitute, as opposed to the traditional view of spore-producing plants as efficient dispersers, a constraint for migration. This casts doubts about the ability of the species to face the massive extinctions predicted in the southern areas, threatening their status of reservoir of genetic diversity.

    Along the nearly 3,200 kilometers (almost 2,000 miles) of the United States–Mexican border, we are witnessing the expression of the challenges of the 21st century. The Borderlands have become a microcosm for the entire United States and Mexico; the issues faced in that region are felt throughout both nations—water availability and quality, ecosystem health, natural resource needs, safety from natural hazards, and human socioeconomic well-being. If these issues were not challenging enough, we now recognize that the difficulties of addressing them are exacerbated by the onset of climate change, and as we come to better understand the complexities of the components of these challenge themes, we discover that each part is inextricably intertwined with other overarching issues. Further, because we are a creative and progressive society, we all seek to understand and appreciate the natural environments associated with the Borderlands while at the same time benefitting from the region’s many social and economic values. It is little wonder that we as a society find it increasingly difficult to ask the right questions, much less find suitable answers to the questions we do ask. For the many scientists who have worked in the Borderlands and contributed to the preceding chapters, this circular is a way to describe to the two nations of the region the capabilities the U.S. Geological Survey can provide to assist in that quest for knowledge and understanding in preparation for the future.

    Exploring the impact of dimensionality on the quantum dynamics of interacting bosons in traps including particle correlations is an interesting but challenging task. Due to the different participating length scales, the modelling of the short-range interactions in three dimensions plays a special role. We review different approaches for the latter and elaborate that for multi-configurational computational strategies, finite-range potentials are adequate resulting in the need for large grids to resolve the relevant length scales. This results in computational challenges, which include the exponential scaling of complexity with the number of atoms. We show that the recently developed ab initio multi-layer multi-configurational time-dependent Hartee method for bosons (ML-MCTDHB) (2013 J. Chem. Phys. 139 134103) can face both numerical challenges and present an efficient numerical implementation of ML-MCTDHB in three spatial dimensions, particularly suited to describe the quantum dynamics for elongated traps. The beneficial scaling of our approach is demonstrated by studying the tunnelling dynamics of bosonic ensembles in a double well. Comparing three-dimensional with quasi-one dimensional simulations, we find dimensionality-induced effects in the density. Furthermore, we study the crossover from weak transversal confinement, where a mean-field description of the system is sufficient, towards tight transversal confinement, where particle correlations and beyond mean-field effects are pronounced.

    Full Text Available In the paper, divided into two parts, a problem of advancements in maritime education and research facing the 21st century challenges, based on the case study of the Gdynia Maritime University (GMU experience is discussed. Part I is devoted to the advances in the maritime education and research towards the challenges in a global meaning. The maritime education challenges are focused on contribution of the University’s representatives in full implementation of the STCW 1978 as amended in 2010 convention, and on the flexible adoption of the academic specializations and programmes to the European and National Qualifications Frameworks, as well as to the needs of a global and local labour market. The research advancements in the maritime universities are basically oriented to marine transport problems, and their main focus is concentrated on the implementation of new technologies, effective and reliable technical and organizational solutions, friendly for users and environment. Part II is dedicated to the Gdynia Maritime University experiencing the 21st century challenges. In this part, firstly the education and research potential of the Gdynia Maritime University, as the one of the world-leading maritime universities, is shortly presented. And next, the GMU’s contribution and good practices concerning the participation in modification of the processes of the IMO STCW 78/2010 convention, adoption of programmes into the international and national qualification frameworks’ standards and procedures, as well as the development of research addressed to a new technological and organizational solution are described and analyzed.

    Full Text Available Poor people with disabilities who live in poor rural societies experience unique problems in accessing health services. Their situation is influenced by multiple factors which unfold and interplay throughout the person’s life course. The difficulties do not only affect the person with a disability and his or her family, but also impact on the relevant care unit. The barriers are rooted in a life in poverty, upheld and maintained by poverty-reinforcing social forces of the past and the present, and reinforced by the lack of the person’s perspective of the health services. This article explores how difficulties may interact and influence access to and utilisation of health services, and how this may render health services out of reach even when they are available. The study reveals that non-compliance is not necessarily about neglect but could as well be a matter of lived poverty. The study was based on in-depth interviews with people with disabilities and family members, and semi-structured interviews with health personnel. The data analysis is contextual and interpretive. When offering health services to people with disabilities living in resource-poor settings, services should take into consideration the person’s history, the needs, and the resources and abilities of the family group. Rethinking access to health services should transcend a narrow medical institutionalization of health professional’s training, and include a patient’s perspective and a social vision in understanding and practice. Such rethinking requires health service models that integrate the skills of health professionals with the skills of disabled people and their family members. Such skills lie dormant at community level, and need to be recognized and utilized.

    Full Text Available In Human Resource Management (HRM, Recruitment is the first and foremost issue to be considered with full of sincerity, because its role is to create a positive impression about the employer in the job market by ensuring effective stimuli for the job seekers. At the beginning, the study sets a picture that focuses on the importance of effective recruitment in the hospitality sector of Bangladesh and then the study details obligatory determinants of attracting efficient human resource for the development of this sector. The main objective of the paper is to study the status and the scopes of recruitment function in hospitality industry with focus towards star rated residential hotels. This study is based on primary data collection through a formal questionnaire. The questionnaire was of mixed mode with most questions in likert-type scale and few were dichotomous in nature. The key finding of the study is that recruitment is a highly challenging task in hospitality and it is quite evident that attractive compensation package is the key factor to attract potential employees. The need and scope to modernize the recruitment practices along with the line of company and employer branding ideas are also recommended in details. There is a long way to go on the way of conceptualizing and actualizing recruitment functions and practices. A paper like this can help to discuss and debate on the necessity of developing better recruitment cultural and conceptual change in these sectors.

    The complexity of providing healthcare to people with HIV/Aids requires investment in comprehensive action and care, constituting a challenge for the multidisciplinary work teams to build an interdisciplinary practice. This study sought to analyze comprehensive healthcare in the Specialized Assistance Services for HIV/Aids (SAE-HIV/Aids) in Recife, in the State of Pernambuco, starting with the process and organization of team work. This is a case study developed in three SAE-HIV/Aids units, based on a qualitative approach using different research techniques. The results show that SAE-HIV/Aids have complied with most of the Brazilian Health Ministry recommendations in terms of basic infrastructure, though none of them had a team of appropriate size. These services have shown signs of fragmentation and difficulty in establishing a systematic intersectorial and interdisciplinary practice, with failings in ensuring the reference and counter-reference flow. It was seen that there was little appreciation of the role of the manager as team leader. The need to perceive the user as a whole was identified, as well as for the team to work in a coordinated manner in order to ensure communicative and relational activities.

    2015-01-01

    An overview is presented of the space radiation environment and its effects on electrical, electronic, and electromechanical parts. Relevant test standards and guidelines are listed. Test standards and guidelines are necessary to ensure best practices, minimize and bound systematic and random errors, and to ensure comparable results from different testers and vendors. Test standards are by their nature static but exist in a dynamic environment of advancing technology and radiation effects research. New technologies, failure mechanisms, and advancement in our understanding of known failure mechanisms drive the revision or development of test standards. Changes to standards must be weighed against their impact on cost and existing part qualifications. There must be consensus on new best practices. The complexity of some new technologies exceeds the scope of existing test standards and may require development of a guideline specific to the technology. Examples are given to illuminate the value and limitations of key radiation test standards as well as the challenges in keeping these standards up to date.

    Full Text Available This article analyses the various challenges facing use of energy for sustainable tourism development in Zimbabwe on the backdrop of Zimbabwe’s reliance mainly on non-renewable energy sources such as fossil fuels and wood whilst very little use is being made of the abundant renewable sources of energy for instance the sun and wind technologies. It is based on the research carried out with the objective of establishing policies that can promote the sustainable use of renewable energy sources in the country. The findings reveal that stakeholders in the tourism and hospitality industry are largely in favour of formulating and expanding policies that encourage use of solar and wind technologies, at the same time mitigating environmental degradation. The article summarises the findings and duly recommends policies than can be used in Zimbabwe to promote the sustainable use of renewable energy employing solar and wind among others for tourism development.

    2016-03-01

    Full Text Available The current “Barrio Antiguo” (Old Quarter of Monterrey (Mexico, formerly known as "Cathedral Quarter", is a postmodern product arising from the intervention between 1988 and 1994 in a sector called First Square, shortly after the construction of the “Macroplaza” (1979-1985 destroyed a significant part of that same sector. Thus, “Barrio Antiguo” became an example of consciousness cleansing experience. The area is a part of what would become the center of Monterrey, whose physical and conceptual boundaries are still undefined. After a harsh period of degradation in the quarter, especially profound in the context of organized crime and its resulting violence in recent years, the Municipal Institute for Planning and Coexistence of Monterrey (IMPLANC has undertaken the task of regenerating the area. The aim of this lecture is to reveal the difficulties faced by the previously mentioned regeneration, starting with the "inferiority complex" that stirs up among the Monterrey population –traditionally-identified with the official discourse of "greatness"– due to the humility of both the architecture and the vernacular northeastern atmosphere of the quarter, especially when comparisons are made with national historic centers which are World Heritage Sites. El actual Barrio Antiguo de Monterrey, antaño conocido como “Barrio de Catedral”, es un producto posmoderno que surge de la intervención realizada entre 1988 y 1994 en un sector del llamado Primer Cuadro de la ciudad, poco después de que las obras de la Macroplaza (1979-85 destruyeran una parte importante de ese mismo sector. Barrio Antiguo vino a ser así una especie de lavado de conciencia. La zona es una parte de lo que sería el centro histórico de Monterrey, cuyos límites físicos y conceptuales aún están sin definir.

    Full Text Available Relative to healthy controls, anxiety-disorder patients show anomalies in classical conditioning that may either result from, or provide a risk factor for, clinically relevant anxiety. Here, we investigated whether healthy participants with enhanced anxiety vulnerability show abnormalities in a challenging affective-conditioning paradigm, in which many stimulus-reinforcer associations had to be acquired with only few learning trials. Forty-seven high and low trait-anxious females underwent MultiCS conditioning, in which 52 different neutral faces (CS+ were paired with an aversive noise (US, while further 52 faces (CS- remained unpaired. Emotional learning was assessed by evaluative (rating, behavioral (dot-probe, contingency report, and neurophysiological (magnetoencephalography measures before, during, and after learning. High and low trait-anxious groups did not differ in evaluative ratings or response priming before or after conditioning. High trait-anxious women, however, were better than low trait-anxious women at reporting CS+/US contingencies after conditioning, and showed an enhanced prefrontal cortex activation towards CS+ in the M1 (i.e., 80 to 117 ms and M170 time intervals (i.e., 140 to 160 ms during acquisition. These effects in MultiCS conditioning observed in individuals with elevated trait anxiety are consistent with theories of enhanced conditionability in anxiety vulnerability. Furthermore, they point towards increased threat monitoring and detection in highly trait-anxious females, possibly mediated by alterations in visual working memory.

    Along the United States–Mexican border, the health of communities, economies, and ecosystems is inextricably intertwined with the availability and quality of water, but effective water management in the Borderlands is complicated. Water users compete for resources, and their needs are increasing. Managers are faced with issues such as finding a balance between agriculture and rapidly growing cities or maintaining public supplies while ensuring sufficient resources for aquatic ecosystems. In addition to human factors, the dry climate of the Borderlands, as compared to more temperate regions, also increases the challenge of balancing water supplies between humans and ecosystems. Warmer, drier, and more variable conditions across the southwestern United States—the projected results of climate change (Seager and others, 2007)—would further stress water supplies.

    Historically, international borders were located far from the major political and economic capitals of their countries and rarely received adequate planning or infrastructure development. Today, as a result of global economics and increased movement of goods between nations, border regions play a much greater role in commerce, tourism, and transportation. For example, Mexico is the second largest destination for United States exports (Woodrow Wilson Center Mexico Institute, 2009). The rapid population and economic growth along the United States–Mexican border, undocumented human border crossings, and the unique natural diversity of resources in the Borderlands present challenges for border security and environmental protection. Assessing risks and implementing sustainable growth policies to protect the environment and quality of life greatly increase in complexity when the issues cross an international border, where social services, environmental regulations, lifestyles, and cultural beliefs are unique for each country. Shared airsheds, water and biological resources, national security issues, and disaster management needs require an integrated binational approach to assess risks and develop binational management strategies.

    Relying on a niche inheritance perspective, this paper discusses the long-term spatial and temporal dynamics of land-use management, agricultural decision making and patterns of resource availability in the tropical lowlands of Central America. We introduce and describe ongoing research that addresses a series of long standing questions about coupled natural and human history dynamics in the Central Maya lowlands, emphasizing the role of landscape and region to address these questions. First, we summarize the results of a CNH pilot study focused on the evolution of the regional landscape of Tikal, Guatemala. Particular attention is centered on how we integrated landscape survey, traditional archaeology and soil studies to understand the spatial and temporal dynamics of agricultural land use and intensification over a two thousand period. Additionally, we discuss how these results were integrated into remote sensing, hydrological and erosion models to better understand how past changes in available water and productive land compare to what we know about settlement patterns in the Tikal Region over that same time period. We not only describe how the Maya transformed this landscape, but also how the region influenced changing patterns of settlement and land use. We finish this section with a discussion of some of the unique challenges integrating archaeological information to study CNH dynamics during this pilot study. Second, we introduce a new project designed to `scale up' the pilot study for a macro-regional analysis of the lowland Maya landscape. The new project leverages a uniquely sampled LIDAR data set designed to refine measurements of above ground carbon storage. Our new project quantitatively examines these data for evidence for past human activity. Preliminary results offer a promising path for tightly integrating archaeology, natural science, remote sensing and modeling for studying CNH dynamics in the deep and recent past.

    Full Text Available European cities and regions are facing the crucial challenge of greening their economy towards more sustainable patterns. Politicians and policy-makers should promote new policies for sustainable growth including renewables, greenhouse gas emissions, energy efficiency and biodiversity. All of these aspects can be considered as a boost for local and regional economy. In this regard, European countries and regions can benefit from the Europe 2020 Strategy which is defined as Europe’s blueprint for a smart, sustainable and inclusive future, providing a ten year roadmap for growth and jobs. EU2020S was designed as a European exit strategy from the global economic and financial crisis in view of new European economic governance. This study discusses the above issues regarding Italy and intends to provide some answers on the perspectives of the new EU2020S. It draws from a research project supported by ESPON, the S.I.E.S.T.A. Project, focused on the territorial dimension of the EU2020S. Therefore, this paper aims at analyzing Italian regional patterns on climate change, green economy and energy within the context of EU2020S and at providing policy recommendations for better achieving the goals of the Strategy.

    Continuous increase of elderly patients with multimorbidity and Emergency Department (ED) overcrowding are great challenges for modern medicine. Traditional hospital organizations are often too rigid to solve them without consistently rising healthcare costs. In this paper we present a new organizational model achieved at Internal Medicine and Critical Subacute Care Unit of Parma University Hospital, Italy, a 106-bed internal medicine area organized by intensity of care and specifically dedicated to such patients. The unit is partitioned into smaller wards, each with a specific intensity level of care, including a rapid-turnover ward (mean length of stay principles. In 2012-2014, this organizational model, compared with other peer units of the hospital and of other teaching hospitals of the region, showed a better performance, efficacy and effectiveness indexes calculated on Regional Hospital Discharge Records database system, allowing a capacity to face a massive (+22 %) rise in medical admissions from the ED. Further studies are needed to validate this model from a patient outcome point of view.

    Full Text Available Aim: Both brain tumors and their treatments have a major negative impact on the quality of life (QoL. EORTC BN20 and Functional Assessment of Cancer Therapy-Brain (FACT-BR are the most commonly used tools to assess QoL. The FACT-BR is a 23-item questionnaire, especially about the psychosocial aspects of QoL. This paper describes the challenges we faced during the process of translation and validation of the FACT-BR into Malayalam. Methods: We first screened the patients to ensure their mental status was satisfactory and that they could communicate well in both languages. According to the Functional Assessment of Chronic Illness Therapy methodology, there were two forward translations from English to Malayalam by two independent translators, a reconciliation of the two forward translations, a back-translation into English, a review/finalization by a fifth translator, proofreading, and then testing on a small cohort of patients. Results: The whole process of translation was fraught with small and large hurdles – from small technical issues to the gaps in sociocultural norms. The sub item BR 7, due to the lack of an exact equivalent word, had issues that persisted up to the validation phase. The postquestionnaire debriefing interviews confirmed that the translations were well understood and conceptually equivalent to the original English one. Conclusions: Translation of the FACT-BR into Malayalam nearly completely reproduced the concepts of the original English questionnaire, as proved in the subsequent validation process.

    Egypt which has more advanced higher education in the Arab world has cultivated several Nobel Prize winners. The last century in the late 1980s, Egypt had early realized higher education popularity while many serious problems and challenges are facing its higher education system. Such as the contradiction between centralized management system of higher education and University autonomy, as well as the confusion and inequality which are brought about by two paralleling education system: the secular system and the religious ,or Al-Azhar system. Facing its history and current situation of higher education, Egyptian government persists in implementing the education development strategy to explore the way to cope with and get rid of dilemma. However, it is still a difficult problem for Egyptian government to realize the coordination between education and economy society.%埃及是阿拉伯世界高等教育比较发达的国家,相继培养出多位诺贝尔奖获得者.20世纪八十年代中后期,在埃及较早进入高等教育大众化阶段的同时,其高等教育系统也面临着许多严重的问题与挑战,如高等教育中央集权管理体制与大学自治的矛盾,以世俗教育和宗教教育为中心的双轨教育体制所带来的不平等和混乱等.针对其高等教育的历史与现状,埃及政府坚持实施教育兴国的现代化发展战略,积极探索应对之道,努力摆脱困境.但如何使教育和经济社会协调发展,依然是摆在埃及政府面前的一道难题.

    Full Text Available BACKGROUND/AIMS: HBV has been classified into ten genotypes (A-J and multiple subgenotypes, some of which strongly influence disease outcome and their distribution also correlate with human migration. HBV infection is highly prevalent in India and its diverse population provides an excellent opportunity to study the distinctiveness of HBV, its evolution and disease biology in variegated ethnic groups. The North-East India, having international frontiers on three sides, is one of the most ethnically and linguistically diverse region of the country. Given the paucity of information on molecular epidemiology of HBV in this region, the study aimed to carry out an in-depth genetic characterization of HBV prevailing in North-East state of Tripura. METHODS: From sera of chronically HBV infected patients biochemical/serological tests, HBV DNA quantification, PCR-amplification, sequencing of PreS/S or full-length HBV genomes were done. HBV genotype/subgenotype determination and sequence variability were assessed by MEGA5-software. The evolutionary divergence times of different HBV subgenotypes were estimated by DNAMLK/PHYLIP program while jpHMM method was used to detect any recombination event in HBV genomes. RESULTS: HBV genotypes D (89.5%, C (6.6% and A (3.9% were detected among chronic carriers. While all HBV/A and HBV/C isolates belonged to subgenotype-A1 and C1 respectively, five subgenotypes of HBV/D (D1-D5 were identified including the first detection of rare D4. These non-recombinant Indian D4 (IndD4 formed a distinct phylogenetic clade, had 2.7% nucleotide divergence and recent evolutionary radiation than other global D4. Ten unique amino acids and 9 novel nucleotide substitutions were identified as IndD4 signatures. All IndD4 carried T120 and R129 in ORF-S that may cause immune/vaccine/diagnostic escape and N128 in ORF-P, implicated as compensatory Lamivudine resistance mutation. CONCLUSIONS: IndD4 has potential to undermine vaccination

    Full Text Available Abstract Introduction Nausea and vomiting in an adolescent, though common presenting symptoms, often pose a diagnostic and therapeutic challenge to the physician. When the diagnosis involves both medical and psychiatric components, management can be complex, especially in the current healthcare system in the United States. To the best of our knowledge, there have been no previous publications detailing successful management of a patient with anorexia nervosa and superior mesenteric artery syndrome. Case presentation We report the case of a 16-year-old Caucasian girl who presented to our emergency department with nausea, abdominal pain, diminished appetite and vomiting. Her history and examination were notable for a 15 kg weight loss and diffuse abdominal tenderness. A barium swallow X-ray with small bowel follow-through and computed tomography scan demonstrated remarkable duodenal narrowing between the superior mesenteric artery and the aorta, consistent with superior mesenteric artery syndrome. Initial management focused on relieving the obstruction and supporting the nutritional needs of the patient. Further history confirmed a diagnosis of anorexia nervosa, requiring intensive psychiatric and medical management, and necessitating a multifaceted approach to patient care involving social work, multiple primary care physicians and subspecialists, insurance company representatives, and the patient's immediate family. Conclusion This case illustrates important points regarding the pathogenesis of superior mesenteric artery syndrome in the setting of anorexia, and it highlights the complexities that arise when managing an adolescent with both medical and psychiatric needs, as well as outlining a viable solution. While superior mesenteric artery syndrome is an uncommon cause of small bowel obstruction, the general pediatrician and child psychiatrist should be aware of this complication of anorexia nervosa.

In order to prevent morbidity and mortality due to opportunistic infections in children, the World Health Organization recommends the use of prophylaxis using co-trimoxazole. However, the challenges affecting effective implementation of this policy in Tanzania have not been documented.Aim: In this study, we assessed the challenges facing the provision of co-trimoxazole prophylaxis among children born to HIV-infected mothers in the public hospitals of Dar es Salaam, Tanzania.Methodology: Four hundred and ninety-eight infants' PMTCT (Prevention of Mother-to-Child Transmission of HIV register books for the past 2 years were reviewed to obtain information regarding the provision of co-trimoxazole prophylaxis. One hundred and twenty-six health care workers were interviewed to identify success stories and challenges in the provision of co-trimoxazole prophylaxis in children. In addition, 321 parents and guardians of children born to HIV-infected mothers were interviewed in the health facilities.Results: Approximately 80% of children were initiated with co-trimoxazole prophylaxis within 2 months after birth. Two hundred and ninety-one (58.4% children started using co-trimoxazole within 4 weeks after birth.

    Abstract Background  There is interest in interventions that provide support for patients facing challenging decisions, such as the choice between mastectomy and breast conservation surgery for breast cancer. However, it is difficult to implement these interventions. One potential source of resistance is the attitudes of clinicians. Objective  To examine specialist breast clinicians’ opinions about the provision of decision support interventions (DesIs) for patients. Methods  As part of the development of a web‐based DesI (BresDex), semi‐structured interviews were conducted with specialist clinicians [breast surgeons, breast care nurses (BCNs) and oncologists] from four breast units in a UK region, and speciality national opinion leaders. Interviews were recorded, transcribed and analysed using the Framework approach. Results  A majority of the 24 clinicians interviewed did not have a working knowledge of DesIs and were ambivalent or sceptical. Many expressed conflicting opinions: they noted the potential benefits, but at the same time expressed reservations about information overlap, overload and about content that they considered inappropriate. Many wanted access to DesIs to be always under clinical supervision. In particular, they were uncertain as regards how DeSIs could be tailored to individual patients’ needs and also accommodate clinical practice variation. BCNs were particularly concerned that DesIs might induce patient anxiety and replace their role. Conclusions  The concept of providing interventions to support patients in decision‐making tasks generated concern, defensiveness and scepticism. These attitudes will be a significant barrier. Implementation efforts will need to recognize and address these issues if these interventions are to become embedded in clinical practice. PMID:21029281

    The Space Launch System (SLS) is the new NASA heavy lift launch vehicle and is scheduled for its first mission in 2017. The goal of the first mission, which will be uncrewed, is to demonstrate the integrated system performance of the SLS rocket and spacecraft before a crewed flight in 2021. SLS has many of the same logistics challenges as any other large scale program. Common logistics concerns for SLS include integration of discreet programs geographically separated, multiple prime contractors with distinct and different goals, schedule pressures and funding constraints. However, SLS also faces unique challenges. The new program is a confluence of new hardware and heritage, with heritage hardware constituting seventy-five percent of the program. This unique approach to design makes logistics concerns such as commonality especially problematic. Additionally, a very low manifest rate of one flight every four years makes logistics comparatively expensive. That, along with the SLS architecture being developed using a block upgrade evolutionary approach, exacerbates long-range planning for supportability considerations. These common and unique logistics challenges must be clearly identified and tackled to allow SLS to have a successful program. This paper will address the common and unique challenges facing the SLS programs, along with the analysis and decisions the NASA Logistics engineers are making to mitigate the threats posed by each.

Moreover, the sediment stabilising capacities of a dense coral cover facilitated sediment accumulation on Challenger Mound in the general erosive/non-depositional Pliocene environment present along the NE Atlantic continental margin. A unique, higher resolution record is hence preserved in the lower mound sequence. Overall, the potential of cold-water coral carbonate mounds as intermediate water depth, continental margin, Plio-Pleistocene palaeo-archives is showcased.

  7. Decoding of faces and face components in face-sensitive human visual cortex

    Directory of Open Access Journals (Sweden)

    David F Nichols

    2010-07-01

    Full Text Available A great challenge to the field of visual neuroscience is to understand how faces are encoded and represented within the human brain. Here we show evidence from functional magnetic resonance imaging (fMRI for spatially distributed processing of the whole face and its components in face-sensitive human visual cortex. We used multi-class linear pattern classifiers constructed with a leave-one-scan-out verification procedure to discriminate brain activation patterns elicited by whole faces, the internal features alone, and the external head outline alone. Furthermore, our results suggest that whole faces are represented disproportionately in the fusiform cortex (FFA whereas the building blocks of faces are represented disproportionately in occipitotemporal cortex (OFA. Faces and face components may therefore be organized with functional clustering within both the FFA and OFA, but with specialization for face components in the OFA and the whole face in the FFA.

    A hybrid course formally integrates the best pedagogical practices in a face-to-face class with the unique opportunities and flexibility inherent in an on-line class. I will describe a general astronomy course "The Universe in Ten Weeks" that was developed as a hybrid astronomy course at Cal Poly Pomona. Students interacted on a daily basis in discussions and observations. Class meetings were enormously productive and active. The instructor has daily feedback and came to class knowing the issues and questions that the students faced in their reading and on-line discussions. He knew before the face-to-face class meetings what conceptual challenges the students faced and what they wanted to research further. I will describe many of the techniques as well as the syllabus that made this class so successful for student learning.

    大气二氧化碳浓度升高、温度上升、降雨分布不均、灾害性天气出现频次增加等全球气候变化,深刻改变着农林生态系统昆虫群落的组成结构、功能和演替,使昆虫分布区域扩大、发生世代增多、生态适应性变异,从而影响了原有的植物-害虫-天敌间内在联系和各营养层间的固有平衡格局,最终导致一些害虫暴发成灾,一些昆虫种群数量下降,甚至一些昆虫物种灭绝.本文在综述昆虫对温度升高、干旱、温室气体(CO2、O3)变化响应研究的基础上,提出我国未来应围绕害虫对全球气候变化的响应特征、适应机制及其控制新方法3个关键的科学问题,通过长期监测、控制试验和模型预测结合,重点开展4个领域的研究工作,以应对全球气候变化下昆虫发生、控制与保护的新挑战.%Global climate change, such as elevated CO2 and O3 concentrations, rising temperature and the uneven distribution of rainfall has a profound impact on insect community composition and the interaction between host plants, and pest insects and their natural enemies. Insect responses to global climate change are frequently "species-specific" and can be negative, positive or neutral. Global climate change has been associated with an increase in the number of pest insect outbreaks, a decline in some insect populations, and even the extinction of some insect species. This review examines the effects of climate change including those in temperature, rainfall and greenhouse gases (CO2, O3), on insects. There are still many challenges facing entomologists in predicting and monitoring the impacts of climate change on insects. Future research needs to focus on the response characteristics and adaptive mechanisms of insects, and developing new control methods for insect pests through long - term monitoring, control experiments and predictive modeling.

    Variance pose is an important research topic in face recognition. The alteration of distance parameters across variance pose face features is a challenging. We provide a solution for this problem using perspective projection for variance pose face recognition. Our method infers intrinsic camera parameters of the image which enable the projection of the image plane into 3D. After this, face box tracking and centre of eyes detection can be identified using our novel technique to verify the virtual face feature measurements. The coordinate system of the perspective projection for face tracking allows the holistic dimensions for the face to be fixed in different orientations. The training of frontal images and the rest of the poses on FERET database determine the distance from the centre of eyes to the corner of box face. The recognition system compares the gallery of images against different poses. The system initially utilises information on position of both eyes then focuses principally on closest eye in order to gather data with greater reliability. Differentiation between the distances and position of the right and left eyes is a unique feature of our work with our algorithm outperforming other state of the art algorithms thus enabling stable measurement in variance pose for each individual.

    2015-08-01

    Full Text Available Face veins based personal identification is a challenging task in the field of identity verification of a person. It is because many other techniques are not identifying the uniqueness of a person in the universe. This research paper finds the uniqueness of a person on the basis of face veins based technique. In this paper five different persons face veins images have been used with different rotation angles (left/right 900 to 2700 and 3150 . For each person, eight different images at different rotations were used and for each of these images the same minimum cost minutiae tree (MCMT is obtained. Here, Prim‟s or Kruskal‟s algorithm is used for finding the MCMT from a minutiae graph. The MCMT is traversed in pre-order to generate the unique string of vertices and edge lengths. We deviated the edge lengths of each MCMT by five pixels in positive and negative directions for robustness testing. It is observed in our experiments that the traversed string which consists of vertices and edge lengths of MCMT is unique for each person and this unique sequence is correctly identifying a person with an accuracy of above 95%. Further, we have compared the performance of our proposed technique with other standard techniques and it is observed that the proposed technique is giving the promising result.

    morango do DF mais eficiente e seletivo.In this article, I had highlighted the results of a survey carried out in 2009 on the situation and difficulties faced by strawberry growers, characterized as smallholders, in the Federal District (DF, Brazil. In addition, I discuss some alternatives to mitigate these problems. The most cited challenges identified by smallholders were, in order of importance: (1 incidence of pests and diseases; (2 strawberry plantlet acquisition; (3 packing costs; (4 need of intensive labor; and (5 high production costs. Based on these information, some possible measures to improve the social and economic status of the smallholders involved in the strawberry production in DF are: (a local production of plantlets, with sanitary quality and affordable costs, to reduce the dependence on other Brazilian States; (b a more intensive use of the several public and private universities, science and technology institutions and rural extension services available in DF to support the sector; (c creation of an association or cooperative to scale up production, access distinct market niches and strengthen the political influence of the sector; (d improve the postharvest handling system by adopting modern packing materials and refrigeration; (e adopt modern traceability tools, so as to increase the local strawberry added value and, therefore, access more demanding markets; (f implement and join the "Strawberry Integrated Production Program (PIMo", officially launched by the Brazilian Ministry of Agriculture, Livestock and Food Supply in 2006; (g survey the local strawberry market and consumer demands to develop a strategic marketing plan to serve the distinct market segments. The increasing consumers' demand for fruit quality and certified and residue free products will surely push the strawberry production system in DF into a scenario of efficiency and excellence.

    rsons of interest among the billions of shared photos on these websites. Despite significant progress in face recognition, searching a large collection of unconstrained face images remains a difficult problem. To address this challenge, we propose a face search system which combines a fast search procedure, coupled with a state-of-the-art commercial off the shelf (COTS) matcher, in a cascaded framework. Given a probe face, we first filter the large gallery of photos to find the top-k most similar faces using features learned by a convolutional neural network. The k retrieved candidates are re-ranked by combining similarities based on deep features and those output by the COTS matcher. We evaluate the proposed face search system on a gallery containing 80 million web-downloaded face images. Experimental results demonstrate that while the deep features perform worse than the COTS matcher on a mugshot dataset (93.7% vs. 98.6% TAR@FAR of 0.01%), fusing the deep features with the COTS matcher improves the overall performance (99.5% TAR@FAR of 0.01%). This shows that the learned deep features provide complementary information over representations used in state-of-the-art face matchers. On the unconstrained face image benchmarks, the performance of the learned deep features is competitive with reported accuracies. LFW database: 98.20% accuracy under the standard protocol and 88.03% TAR@FAR of 0.1% under the BLUFR protocol; IJB-A benchmark: 51.0% TAR@FAR of 0.1% (verification), rank 1 retrieval of 82.2% (closed-set search), 61.5% FNIR@FAR of 1% (open-set search). The proposed face search system offers an excellent trade-off between accuracy and scalability on galleries with millions of images. Additionally, in a face search experiment involving photos of the Tsarnaev brothers, convicted of the Boston Marathon bombing, the proposed cascade face search system could find the younger brother's (Dzhokhar Tsarnaev) photo at rank 1 in 1 second on a 5M gallery and at rank 8 in 7

    It is widely accepted that emotion processing difficulties are involved in Autism Spectrum Conditions (ASC). An increasing number of studies have focused on the development of training programs and have shown promising results. However, most of these programs are appropriate for individuals with high-functioning ASC (HFA) but exclude individuals with low-functioning ASC (LFA). We have developed a computer-based game called JeStiMulE based on logical skills to teach emotions to individuals with ASC, independently of their age, intellectual, verbal and academic level. The aim of the present study was to verify the usability of JeStiMulE (which is its adaptability, effectiveness and efficiency) on a heterogeneous ASC group. We hypothesized that after JeStiMulE training, a performance improvement would be found in emotion recognition tasks. A heterogeneous group of thirty-three children and adolescents with ASC received two one-hour JeStiMulE sessions per week over four weeks. In order to verify the usability of JeStiMulE, game data were collected for each participant. Furthermore, all participants were presented before and after training with five emotion recognition tasks, two including pictures of game avatars (faces and gestures) and three including pictures of real-life characters (faces, gestures and social scenes). Descriptive data showed suitable adaptability, effectiveness and efficiency of JeStiMulE. Results revealed a significant main effect of Session on avatars (ANOVA: F (1,32) = 98.48, P < .001) and on pictures of real-life characters (ANOVA: F (1,32) = 49.09, P < .001). A significant Session × Task × Emotion interaction was also found for avatars (ANOVA: F (6,192) = 2.84, P = .01). This triple interaction was close to significance for pictures of real-life characters (ANOVA: F (12,384) = 1.73, P = .057). Post-hoc analyses revealed that 30 out of 35 conditions found a significant increase after training. JeStiMulE appears

  9. Important Role of FTO in the Survival of Rare Panresistant Triple-Negative Inflammatory Breast Cancer Cells Facing a Severe Metabolic Challenge.

    Directory of Open Access Journals (Sweden)

    Balraj Singh

    Full Text Available We have previously shown that only 0.01% cells survive a metabolic challenge involving lack of glutamine in culture medium of SUM149 triple-negative Inflammatory Breast Cancer cell line. These cells, designated as SUM149-MA for metabolic adaptability, are resistant to chemotherapeutic drugs, and they efficiently metastasize to multiple organs in nude mice. We hypothesized that obesity-related molecular networks, which normally help in cellular and organismal survival under metabolic challenges, may help in the survival of MA cells. The fat mass and obesity-associated protein FTO is overexpressed in MA cells. Obesity-associated cis-acting elements in non-coding region of FTO regulate the expression of IRX3 gene, thus activating obesity networks. Here we found that IRX3 protein is significantly overexpressed in MA cells (5 to 6-fold as compared to the parental SUM149 cell line, supporting our hypothesis. We also obtained evidence that additional key regulators of energy balance such as ARID5B, IRX5, and CUX1 P200 repressor could potentially help progenitor-like TNBC cells survive in glutamine-free medium. MO-I-500, a pharmacological inhibitor of FTO, significantly (>90% inhibited survival and/or colony formation of SUM149-MA cells as compared to untreated cells or those treated with a control compound MO-I-100. Curiously, MO-I-500 treatment also led to decreased levels of FTO and IRX3 proteins in the SUM149 cells initially surviving in glutamine-free medium as compared to MO-I-100 treatment. Interestingly, MO-I-500 treatment had a relatively little effect on cell growth of either the SUM149 or SUM149-MA cell line when added to a complete medium containing glutamine that does not pose a metabolic challenge. Importantly, once selected and cultured in glutamine-free medium, SUM149-MA cells were no longer affected by MO-I-500 even in Gln-free medium. We conclude that panresistant MA cells contain interconnected molecular networks that govern

    Despite the growth of the IT industry and the high demand for IT skills university departments seem unable to attract enough student to cater for the needs of the profession. There seems to be a misconception about the difference between IT user skills and the discipline of Computing. This article attempts to do three things: 1) reinforce the view that a crisis of IT skills shortage is looming; 2) reiterate the fact that computing science is an exciting discipline that is central to the knowledge economy and that career prospects in IT-related jobs are very good despite the fears surrounding outsourcing and 3) suggest that HE computing departments must be flexible enough to embrace a two-facetted challenge: a) the changing landscape of IT Skills and b) the high hopes and aspirations of the first generation of our digital-native student community.

    Full Text Available A study of both face recognition and detection techniques is carried out using the algorithms like Principal Component Analysis (PCA, Kernel Principal Component Analysis (KPCA, Linear Discriminant Analysis (LDA and Line Edge Map (LEM. These algorithms show different rates of accuracy under different conditions. The automatic recognition of human faces presents a challenge to the pattern recognition community. Typically, human faces are different in shapes with minor similarity from person to person. Furthermore, lighting condition changes, facial expressions and pose variations further complicate the face recognition task as one of the difficult problems in pattern analysis.

    Full Text Available This report, based on clinical practice on a children’s ward in New Zealand, examines the role of short-term music therapy in supporting children and their parents[1] facing the difficulties of hospitalisation. It endeavours to explore three questions. How might music therapy support hospitalised children? How can it support parents of hospitalised children? Is it important/valuable for music therapists working in a paediatric ward to involve parent(s in music therapy sessions? Three hospitalised children (aged 11 months, 5 and 7 years, who were accompanied by a parent, participated in a single individual music therapy session. From the clinical notes, semi-structured interviews with the children’s parents and a staff member, and my own reflective journal it was indicated that music therapy supported the psychosocial needs of the paediatric patients and their parents in many ways. For the children music therapy: 1 promoted normalisation; and 2 provided emotional/psychological support. For parents, it: 1 elicited positive changes in mood; 2 reduced anxiety; and 3 supported parental learning/parenting. Furthermore, the findings suggested that the wellbeing of the parent-child relationship can be supported during music therapy. The importance of parental involvement varied for each case, and highlighted different views between therapist, staff member and parents regarding this. Factors that may determine parental involvement and the benefits of both parental presence and absence during sessions were elicited. The report suggests that music therapy has the potential positively to support paediatric wards in New Zealand to provide an environment that is responsive to the psychosocial needs of hospitalised children and their parents

    Full Text Available Introduction: This study aimed to identify the challenges of risk management in the context of clinical governance in selected hospitals of Tehran University of Medical Sciences. Materials and Methods:This study was implemented in two phases: qualitative step and quantitative step (survey. The first step was conducted using in-depth interviews and the second was carried out through a survey by questionnaire. Data were collected in hospitals through in-depth interviews with hospitals managers and the experts involved in clinical governance who had been introduced by the hospital manager. All professionals affiliated with clinical governance in Baharloo, Firoozgar, Farabi, Shahid Rajai, Ziaeian, Motahari and Sina hospitals were selected. Results: 35 experts involved in clinical governance were interviewed. According to these experts, the main obstacles in hospital risk management were: Lack of an error reporting culture, exaggerated fear of the consequences, and physicians' lack of interest in this domain. High workloads in this area have led to a reduction in employees' contributions. Conclusion: Establishing clinical governance in health care organizations has had many benefits, such as improving patient care, increased level of patients' satisfaction, establishment of a risk management system, improvement in staff and health-care personnel cooperation, and achieving a more successful organizational management. Appropriate changes in the organizational culture are necessities for the successful establishment of risk management. Human and cultural obstacles that hinder the implementation of risk management in hospitals are evident; thus, major actions are necessary to implement risk management properly in a disciplined manner.

  1. The church’s pastoral role concerning challenges faced by teachers in South-African public schools: Some practical theological perspectives

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Teaching used to be a well-respected profession, which many people used to love in the past.Many children, when asked what they wanted to be when growing up, indicated that theywanted to be teachers. This is why – even when children were play-acting – most of them likedto play the role of a teacher. It is disturbing to learn that this profession has grown to be hated bymany people today. This is evidenced by the mass resignations of teachers from many publicschools over the past few years in South Africa. This exodus had been researched by differentscholars from different disciplines who have also made their recommendations as to how thesituation can be reversed. The fact that teachers, who are disappointed and demotivated tocontinue with the career, are the creation of God and are teaching the creation of God, calls forthe church through its pastoral theological services to play its role in trying to compose guidelinesfor the elimination of the problem. The purpose of this article is to search for possible ways inwhich the church can theologically play its role in addressing the problem of the teachers’dissatisfaction as well as giving some guidelines on how this challenge can be eliminated.

  2. Super-Sonograms and graphical seismic source locations: Facing the challenge of real-time data processing in an OSI SAMS installation

    Science.gov (United States)

    Joswig, Manfred

    2010-05-01

    The installation and operation of an OSI seismic aftershock monitoring system (SAMS) is bound by strict time constraints: 30+ small arrays must be set up within days, and data screening must cope with the daily seismogram input. This is a significant challenge since any potential, single ML -2.0 aftershock from a potential nuclear test must be detected and discriminated against a variety of higher-amplitude noise bursts. No automated approach can handle this task to date; thus some 200 traces of 24/7 data must be screened manually with a time resolution sufficient to recover signals of just a few sec duration, and with tiny amplitudes just above the threshold of ambient noise. Previous tests confirmed that this task can not be performed by time-domain signal screening via established seismological processing software, e.g. PITSA, SEISAN, or GEOTOOLS. Instead, we introduced 'SonoView', a seismic diagnosis tool based on a compilation of array traces into super-sonograms. Several hours of cumulative array data can be displayed at once on a single computer screen - without sacrifying the necessary detectability of few-sec signals. Then 'TraceView' will guide the analyst to select the relevant traces with best SNR, and 'HypoLine' offers some interactive, graphical location tools for fast epicenter estimates and source signature identifications. A previous release of this software suite was successfully applied at IFE08 in Kasakhstan, and supported the seismic sub-team of OSI in its timely report compilation.

  3. Post-Socialist Fathers ‘At Home’ and ‘Away from Home’ in ‘Old Europe’: Facing the Challenge through Masculine Identity Talk

    Directory of Open Access Journals (Sweden)

    Marion Pajumets

    2012-06-01

    Full Text Available This article focuses on those Estonian male migrants to ‘Old Europe’ who spend most of their time in the domestic realm as caring fathers and supportive spouses to their wives, who are meanwhile advancing their transnational careers. In this context, masculine identity talk can be understood in terms of strategies employed in response to the challenge to the men’s masculinity that this atypical life choice is likely to entail. Identity is viewed in this article as a processual phenomenon that is relentlessly, although not always deliberately, (reformulated in discourse, rather than determined by the assigned social roles. Analysis of in-depth interviews reveals that there are varied discourses in use that efficiently reconstruct the interviewees’ sense of personal significance. Interestingly, men predominantly combine ‘alternative’ discourses (‘caring father’, ‘supportive spouse’, ‘civilised adult’, which potentially undermine Estonian idealised masculinity, with the ‘conservative’ discourses (‘professional man’, the ‘well-off’, that reinforce the Estonian male norm. Men draw on a range of potentially oppositional and conflicting resources for constructing masculinity, without much reflexive selection from their part. Hence, the discourses men engage in position the men as much as the men appear to consciously position themselves in the discourses. This poststructuralist account of identity is located within a more structural historical context of transition and change in contemporary Europe.

    Undergraduate research at small schools is becoming the norm rather than the exception that it was years ago. Faculties are now faced with the challenges of incorporating students with varying degrees of academic preparedness and motivation in their research. This coupled with the students' own constraints within the academic schedule can make undergraduate research a challenge for both students and faculty. Like many small undergraduate schools, VMI's faculty and students are faced with these obstacles when engaging in undergraduate research. However, such difficulties can lead to creative solutions that lead to multiple benefits for students and faculty mentors. We present our unique perspective and experiences for this challenging yet rewarding experience as related to thin film research performed at VMI.

    What does it mean to look into the face of a patient who looks back? Face-to-face encounters are at the heart of the patient-clinician relationship but their singular significance is often lost amid the demands of today's high-tech, metric-driven health care systems. Using the framework provided by the philosopher and Holocaust survivor Emmanuel Levinas, the authors explore the unique responsibility and potential for hope found only in face-to-face encounters. Revisiting this most fundamental attribute of medicine is likely our greatest chance to reclaim who we are as clinicians and why we do what we do. © 2017 Annals of Family Medicine, Inc.

    Fung, Ronald K F; Kerridge, Ian H

    2013-02-01

    The discovery of induced pluripotent stem (iPS) cells in 2006 was heralded as a major breakthrough in stem cell research. Since then, progress in iPS cell technology has paved the way towards clinical application, particularly cell replacement therapy, which has refueled debate on the ethics of stem cell research. However, much of the discourse has focused on questions of moral status and potentiality, overlooking the ethical issues which are introduced by the clinical testing of iPS cell replacement therapy. First-in-human trials, in particular, raise a number of ethical concerns including informed consent, subject recruitment and harm minimisation as well as the inherent uncertainty and risks which are involved in testing medical procedures on humans for the first time. These issues, while a feature of any human research, become more complex in the case of iPS cell therapy, given the seriousness of the potential risks, the unreliability of available animal models, the vulnerability of the target patient group, and the high stakes of such an intensely public area of science. Our paper will present a detailed case study of iPS cell replacement therapy for Parkinson's disease to highlight these broader ethical and epistemological concerns. If we accept that iPS cell technology is fraught with challenges which go far beyond merely refuting the potentiality of the stem cell line, we conclude that iPS cell research should not replace, but proceed alongside embryonic and adult somatic stem cell research to promote cross-fertilisation of knowledge and better clinical outcomes.

    2016-04-01

    While guidelines outlining the appropriate management of sport-related concussion have been developed and adapted for use within community sport, it remains unknown how they are experienced by those responsible for implementing them. Longitudinal study. 111 coaches and sports trainers from community-level Australian Football and Rugby League teams completed pre- and post-season surveys assessing their attitudes towards using concussion guidelines. Participants also provided post-season feedback regarding their experiences in using the guidelines. 71% of participants reported using the guidelines in the preceding season. Post-season attitude was related to pre-season attitude (p=0.002), football code (p=0.015), and team role (p=0.045). An interaction between team role and guideline use (p=0.012) was also found, with coaches who had used the guidelines, and sports trainers who had not, reporting more positive post-season attitudes towards using the concussion guidelines. Implementation challenges included disputing of decisions about return-to-play by players, parents, and coaches, and a perceived lack of time. Recommendations for improved guideline materials included using larger fonts and providing for witnessing of advice given to players. This is the first study to examine the implementation of concussion guidelines in community sport. Training of coaches/sports trainers needs enhancement. In addition, new education should be developed for parents/players about the importance of the return-to-play advice given to them by those who follow these guidelines. Information provided by those who attempted to use the guidelines will assist the refinement of implementation and dissemination processes around concussion guidelines across sports.

    Shakeshaft, Nicholas G; Plomin, Robert

    2015-10-13

    Specific cognitive abilities in diverse domains are typically found to be highly heritable and substantially correlated with general cognitive ability (g), both phenotypically and genetically. Recent twin studies have found the ability to memorize and recognize faces to be an exception, being similarly heritable but phenotypically substantially uncorrelated both with g and with general object recognition. However, the genetic relationships between face recognition and other abilities (the extent to which they share a common genetic etiology) cannot be determined from phenotypic associations. In this, to our knowledge, first study of the genetic associations between face recognition and other domains, 2,000 18- and 19-year-old United Kingdom twins completed tests assessing their face recognition, object recognition, and general cognitive abilities. Results confirmed the substantial heritability of face recognition (61%), and multivariate genetic analyses found that most of this genetic influence is unique and not shared with other cognitive abilities.

    This letter presents a face normalization algorithm based on 2-D face model to recognize faces with variant postures from front-view face. A 2-D face mesh model can be extracted from faces with rotation to left or right and the corresponding front-view mesh model can be estimated according to the facial symmetry. Then based on the inner relationship between the two mesh models, the normalized front-view face is formed by gray level mapping. Finally, the face recognition will be finished based on Principal Component Analysis (PCA). Experiments show that better face recognition performance is achieved in this way.

    It has been previously established that extraverts who are skilled at interpersonal interaction perform significantly better than introverts on a face-specific recognition memory task. In our experiment we further investigate the relationship between extraversion and face recognition, focusing on famous face recognition and face matching. Results indicate that more extraverted individuals perform significantly better on an upright famous face recognition task and show significantly larger face inversion effects. However, our results did not find an effect of extraversion on face matching or inverted famous face recognition.

    The human face conveys emotional and social information, but it is not well understood how these two aspects influence face perception. In order to model a group situation, two faces displaying happy, neutral or angry expressions were presented. Importantly, faces were either facing the observer, or they were presented in profile view directed towards, or looking away from each other. In Experiment 1 (n = 64), face pairs were rated regarding perceived relevance, wish-to-interact, and displayed interactivity, as well as valence and arousal. All variables revealed main effects of facial expression (emotional > neutral), face orientation (facing observer > towards > away) and interactions showed that evaluation of emotional faces strongly varies with their orientation. Experiment 2 (n = 33) examined the temporal dynamics of perceptual-attentional processing of these face constellations with event-related potentials. Processing of emotional and neutral faces differed significantly in N170 amplitudes, early posterior negativity (EPN), and sustained positive potentials. Importantly, selective emotional face processing varied as a function of face orientation, indicating early emotion-specific (N170, EPN) and late threat-specific effects (LPP, sustained positivity). Taken together, perceived personal relevance to the observer-conveyed by facial expression and face direction-amplifies emotional face processing within triadic group situations. © The Author (2017).

    2016-05-01

    Recognizing the identity of a face is computationally challenging, because it requires distinguishing between similar images depicting different people, while recognizing even very different images depicting a same person. Previous human fMRI studies investigated representations of face identity in the presence of changes in viewpoint and in expression. Despite the importance of holistic processing for face recognition, an investigation of representations of face identity across different face parts is missing. To fill this gap, we investigated representations of face identity and their invariance across different face halves. Information about face identity with invariance across changes in the face half was individuated in the right anterior temporal lobe, indicating this region as the most plausible candidate brain area for the representation of face identity. In a complementary analysis, information distinguishing between different face halves was found to decline along the posterior to anterior axis in the ventral stream.

    1999-01-01

    Survey findings pointing to the worsening health situation for children in Kenya that were highlighted during the National Dissemination Seminar for the 1998 Kenya Demographic and Health Survey (KDHS). The survey indicates that currently, 1 in 9 Kenyan children does not live to his or her 5th birthday. Under-five mortality stands at 112 deaths per 1000 live births, a 24% increase over the last decade. The high prevalence of childhood mortality is associated with a short preceding birth interval, a low level of maternal education, and rural location (under-five mortality is 23% higher in rural than in urban areas). Moreover, the risk of children dying varies greatly across provinces. A comparison between the results of the 1993 and 1998 KDHS also indicates recent setbacks in the fight against vaccine preventable diseases. Full vaccination coverage has fallen from 79% in 1993 to 65% in 1998. One of the more positive findings is the continuing decline in total fertility rate from 8.1 children per woman in the mid-1970s to current levels of 4.7 children per woman. In addition, knowledge and use of family planning has continued to rise in Kenya. Lastly, participants in the seminar also discussed the need for further dissemination of findings and further analysis of projects.

    2016-01-01

    Faces drive our social interactions. A vast literature suggests an interaction between gender and emotional face perception, with studies using different methodologies demonstrating that the gender of a face can affect how emotions are processed. However, how different is our perception of affective male and female faces? Furthermore, how does our current affective state when viewing faces influence our perceptual biases? We presented participants with a series of faces morphed along an emotional continuum from happy to angry. Participants judged each face morph as either happy or angry. We determined each participant’s unique emotional ‘neutral’ point, defined as the face morph judged to be perceived equally happy and angry, separately for male and female faces. We also assessed how current state affect influenced these perceptual neutral points. Our results indicate that, for both male and female participants, the emotional neutral point for male faces is perceptually biased to be happier than for female faces. This bias suggests that more happiness is required to perceive a male face as emotionally neutral, i.e., we are biased to perceive a male face as more negative. Interestingly, we also find that perceptual biases in perceiving female faces are correlated with current mood, such that positive state affect correlates with perceiving female faces as happier, while we find no significant correlation between negative state affect and the perception of facial emotion. Furthermore, we find reaction time biases, with slower responses for angry male faces compared to angry female faces. PMID:27733839

    Prosopagnosia has largely been regarded as an untreatable disorder. However, recent case studies using cognitive training have shown that it is possible to enhance face recognition abilities in individuals with developmental prosopagnosia. Our goal was to determine if this approach could be effective in a larger population of developmental prosopagnosics. We trained 24 developmental prosopagnosics using a 3-week online face-training program targeting holistic face processing. Twelve subjects with developmental prosopagnosia were assessed before and after training, and the other 12 were assessed before and after a waiting period, they then performed the training, and were then assessed again. The assessments included measures of front-view face discrimination, face discrimination with view-point changes, measures of holistic face processing, and a 5-day diary to quantify potential real-world improvements. Compared with the waiting period, developmental prosopagnosics showed moderate but significant overall training-related improvements on measures of front-view face discrimination. Those who reached the more difficult levels of training ('better' trainees) showed the strongest improvements in front-view face discrimination and showed significantly increased holistic face processing to the point of being similar to that of unimpaired control subjects. Despite challenges in characterizing developmental prosopagnosics' everyday face recognition and potential biases in self-report, results also showed modest but consistent self-reported diary improvements. In summary, we demonstrate that by using cognitive training that targets holistic processing, it is possible to enhance face perception across a group of developmental prosopagnosics and further suggest that those who improved the most on the training task received the greatest benefits.

    Accelerating the development and deployment of energy technologies is a pressing challenge. Doing so will require policy reform that improves the efficacy of public research organizations and strengthens the links between public and private innovators. With their US$14 billion annual budget and unique mandates, the US National Laboratories have the potential to critically advance energy innovation, yet reviews of their performance find several areas of weak organizational design. Here, we discuss the challenges the National Laboratories face in engaging the private sector, increasing their contributions to transformative research, and developing culture and management practices to better support innovation. We also offer recommendations for how policymakers can address these challenges.

    The visual system is tuned for rapid detection of faces, with the fastest choice saccade to a face at 100ms. Familiar faces have a more robust representation than do unfamiliar faces, and are detected faster in the absence of awareness and with reduced attentional resources. Faces of family and close friends become familiar over a protracted period involving learning the unique visual appearance, including a view-invariant representation, as well as person knowledge. We investigated the effect of personal familiarity on the earliest stages of face processing by using a saccadic-choice task to measure how fast familiar face detection can happen. Subjects made correct and reliable saccades to familiar faces when unfamiliar faces were distractors at 180ms—very rapid saccades that are 30 to 70ms earlier than the earliest evoked potential modulated by familiarity. By contrast, accuracy of saccades to unfamiliar faces with familiar faces as distractors did not exceed chance. Saccades to faces with object distractors were even faster (110 to 120 ms) and equivalent for familiar and unfamiliar faces, indicating that familiarity does not affect ultra-rapid saccades. We propose that detectors of diagnostic facial features for familiar faces develop in visual cortices through learning and allow rapid detection that precedes explicit recognition of identity.

  1. Age-invariant face recognition.

    Science.gov (United States)

    Park, Unsang; Tong, Yiying; Jain, Anil K

    2010-05-01

    One of the challenges in automatic face recognition is to achieve temporal invariance. In other words, the goal is to come up with a representation and matching scheme that is robust to changes due to facial aging. Facial aging is a complex process that affects both the 3D shape of the face and its texture (e.g., wrinkles). These shape and texture changes degrade the performance of automatic face recognition systems. However, facial aging has not received substantial attention compared to other facial variations due to pose, lighting, and expression. We propose a 3D aging modeling technique and show how it can be used to compensate for the age variations to improve the face recognition performance. The aging modeling technique adapts view-invariant 3D face models to the given 2D face aging database. The proposed approach is evaluated on three different databases (i.g., FG-NET, MORPH, and BROWNS) using FaceVACS, a state-of-the-art commercial face recognition engine.

  2. Human faces are slower than chimpanzee faces.

    Directory of Open Access Journals (Sweden)

    Anne M Burrows

    Full Text Available BACKGROUND: While humans (like other primates communicate with facial expressions, the evolution of speech added a new function to the facial muscles (facial expression muscles. The evolution of speech required the development of a coordinated action between visual (movement of the lips and auditory signals in a rhythmic fashion to produce "visemes" (visual movements of the lips that correspond to specific sounds. Visemes depend upon facial muscles to regulate shape of the lips, which themselves act as speech articulators. This movement necessitates a more controlled, sustained muscle contraction than that produced during spontaneous facial expressions which occur rapidly and last only a short period of time. Recently, it was found that human tongue musculature contains a higher proportion of slow-twitch myosin fibers than in rhesus macaques, which is related to the slower, more controlled movements of the human tongue in the production of speech. Are there similar unique, evolutionary physiologic biases found in human facial musculature related to the evolution of speech? METHODOLOGY/PRINICIPAL FINDINGS: Using myosin immunohistochemistry, we tested the hypothesis that human facial musculature has a higher percentage of slow-twitch myosin fibers relative to chimpanzees (Pan troglodytes and rhesus macaques (Macaca mulatta. We sampled the orbicularis oris and zygomaticus major muscles from three cadavers of each species and compared proportions of fiber-types. Results confirmed our hypothesis: humans had the highest proportion of slow-twitch myosin fibers while chimpanzees had the highest proportion of fast-twitch fibers. CONCLUSIONS/SIGNIFICANCE: These findings demonstrate that the human face is slower than that of rhesus macaques and our closest living relative, the chimpanzee. They also support the assertion that human facial musculature and speech co-evolved. Further, these results suggest a unique set of evolutionary selective pressures on

    The ever increasing adoption of mobile technologies and ubiquitous services allows to sense human behavior at unprecedented levels of details and scale. Wearable sensors are opening up a new window on human mobility and proximity at the finest resolution of face-to-face proximity. As a consequence, empirical data describing social and behavioral networks are acquiring a longitudinal dimension that brings forth new challenges for analysis and modeling. Here we review recent work on the representation and analysis of temporal networks of face-to-face human proximity, based on large-scale datasets collected in the context of the SocioPatterns collaboration. We show that the raw behavioral data can be studied at various levels of coarse-graining, which turn out to be complementary to one another, with each level exposing different features of the underlying system. We briefly review a generative model of temporal contact networks that reproduces some statistical observables. Then, we shift our focus from surface ...

    Full Text Available Face Recognition (FR under various illuminations is very challenging. Normalization technique is useful for removing the dimness and shadow from the facial image which reduces the effect of illumination variations still retaining the necessary information of the face. The robust local feature extractor which is the gray-scale invariant texture called Local Binary Pattern (LBP is helpful for feature extraction. K-Nearest Neighbor classifier is utilized for the purpose of classification and to match the face images from the database. Experimental results were based on Yale-B database with three different sub categories. The proposed method has been tested to robust face recognition in various illumination conditions. Extensive experiment shows that the proposed system can achieve very encouraging performance in various illumination environments.

    2007-10-01

    Human face transplantation is now a clinical reality. The surgical techniques necessary to perform these procedures have been used routinely in reconstructive microsurgery for many years. From an immunological standpoint since face and hand contain mostly the same tissues it is reasonable to assume that the same immunosuppressive regimen found to be effective in human hand transplants should also work in face transplantation. It is the ethical issues associated with the risks and benefits of performing facial transplantation that have posed the greatest challenges leading up to performing this new procedure. In this editorial, we will review some of the main events that have led to the recently performed human face transplants, specifically focusing on the key ethical issues at the center of this debate. We will discuss how the research and clinical experience in human hand transplantation laid the foundation for performing face transplantation and describe the research and the ethical guidelines upon which a team at the University of Louisville based their position "to move ahead" in spite of much criticism. Finally we will outline some of the key arguments against face transplantation, and conclude with a discussion on what comes next now that the first human face transplants have been performed.

    2016-01-01

    Full Text Available Faces are highly challenging and dynamic objects that are employed as biometrics evidence in identity verification. Recently, biometrics systems have proven to be an essential security tools, in which bulk matching of enrolled people and watch lists is performed every day. To facilitate this process, organizations with large computing facilities need to maintain these facilities. To minimize the burden of maintaining these costly facilities for enrollment and recognition, multinational companies can transfer this responsibility to third-party vendors who can maintain cloud computing infrastructures for recognition. In this paper, we showcase cloud computing-enabled face recognition, which utilizes PCA-characterized face instances and reduces the number of invariant SIFT points that are extracted from each face. To achieve high interclass and low intraclass variances, a set of six PCA-characterized face instances is computed on columns of each face image by varying the number of principal components. Extracted SIFT keypoints are fused using sum and max fusion rules. A novel cohort selection technique is applied to increase the total performance. The proposed protomodel is tested on BioID and FEI face databases, and the efficacy of the system is proven based on the obtained results. We also compare the proposed method with other well-known methods.

    Full Text Available Drawing on critical, socio-cultural and sociolinguistic theories of writing, text and voice, this ethnographic study examines the challenges that a mature ESL student and her instructors in a university course on Spanish Language Media face as they co-construct a common understanding of academic literacy and voice in an undergraduate General Studies Program offered by a university in Western Massachusetts. Intertextual analysis of the data suggests that traditional product-based approaches to helping students develop academic literacy might not be very effective. However, to be able to take a different approach, such as the one suggested by genre scholars, both faculty teaching content subjects and writing tutors would need appropriate training.Con base en teorías criticas, socioculturales y sociolingüísticas sobre escritura académica, texto y voz, este estudio etnográfico explora los retos que enfrentan una estudiante hablante de inglés como segunda lengua y sus profesores de un curso de Medios de Comunicación en Lengua Española al construir conjuntamente los conceptos de literacias académicas y de voz en un curso de pregrado en estudios generales ofrecido por una universidad en Massachusetts. El análisis intertextual de los datos recogidos muestra que algunos métodos tradicionales dirigidos a la elaboración de productos pueden resultar poco efectivos para apoyar el desarrollo de la escritura académica. Sin embargo, se concluye que para usar metodologías mas efectivas, como las propuestas por las teorías de genero, es indispensable que tanto los profesores de las diferentes materias como los tutores reciban el entrenamiento adecuado.

    2012-04-01

    Full Text Available Women involved in all aspects of the United States Armed Forces face mental health needs that are unique from women in the general population. Because the most recent wars in Iraq and Afghanistan are involving more women in combat situations, social workers encounter female clients who are increasingly experiencing post-traumatic stress disorder, substance misuse, and sexual violence. Special attention must be paid particularly to women who serve in the National Guard or Reserves, as they have different concerns than enlisted active duty women. These concerns include less social support and fewer resources upon return from deployment. Thus, it is imperative for social workers in the community to be aware of these military women’s experiences and unique mental health challenges in order to effectively treat their needs.

    2016-01-01

    This research investigates a key concept in East Asia, face, and represents the first attempt to empirically examine the concept of face at the national level. Controlling for the level of national identification, Study 1 employed the scenario experiment method among samples of native Chinese and Taiwanese populations and revealed that national face exhibits patterns reverse of personal face. Using the experimental method, Study 2 replicated the findings of Study 1 and provided support for the different mechanisms underneath national face and personal face. Study 3 replicated the findings of Study 2 and additionally showed that national face exerts a significant inhibitory effect on face process. Findings are discussed in terms of possible implications for intergroup and international relations. Expanding on extant scholarship on face and across three studies with different experimental paradigms, this research turns our attention from face at the personal level to face at the national level by introducing the construct of national face and examining its manifestations in East Asia. The results advance our understanding of the psychological mechanism driving face concern in East Asia. They make a strong and unique case for the psychological existence of national face as an empirically distinct construct and an important psychological resource for East Asians. PMID:27774081

    Connor, Ann; Layne, Laura; Thomisee, Karen

    2010-04-01

    This article highlights the Farm Worker Family Health Program's (FWFHP) strategies for providing care to migrant farm workers residing within a unique social and cultural context. The care provided by health professions students from a variety of disciplines extends and augments the work of the local migrant farm worker clinic that is pushed beyond capacity during peak growing and harvest times. Nursing's social responsibility to care for underserved populations is a guiding principle of the FWFHP and shapes how the work is translated into action. The FWFHP is a community-academic partnership that began in the rural southeastern United States in 1993. Challenges facing migrant farm worker families include access to health care, language, health literacy, housing and sanitation, family and community integrity, and workplace safety. The nursing practice strategies used to address these health challenges may be adapted to strengthen health programs serving other populations who live in poverty or reside in low-resource settings.

    高校女生的发展状况主要从学业与能力表现、职业准备、社会交往、政治和社会事务参与、婚恋状况、身心健康和社会性别观念等七个方面衡量。研究发现,高校女生在学习表现上并不落后于男生;绝大部分女生赞同女性也应该有自己的一番事业;通过寻找兼职及获得职业证书的方式为自己积累求职资本;更偏好与初级群体建立联系,和其他人建立起情感性的密切关系;在政治活动和参与社团活动等方面并不落后,有更多的女生加入社会公益组织;在平衡学业和情感关系上,高校女生表现出一定的优势;高校女生的社会性别观念日趋理性、平等。高校女生有着良好的发展状况和发展环境的同时,也面临着挑战和处于不利的发展环境。%The development status of women college students is measured in these ways: academic performance and ability; vocational preparation; social interactions; political and social engagement; romantic relationships and marital status; mental and physical health; gender consciousness. The research demonstrates women college students do well in their academic outcomes compared to men college students. Most of the researchers hold the opinion that women should have their own careers; accumulating career capital by way of doing part-time work and acquiring professional qualifications; women prefer to establish close relationships with grass-roots groups; many women students take part in volunteer and community service organizations; they also perform better in balancing learning and romantic relationships. The gender consciousness of women students is more rational and equal. On the other hand, they also face challenges and unfavorable environment.

    Full Text Available Bajo el enfoque del Modelo Ecotecnológico observado en las comunidades artesanales de Galapa y Usiacurí del Departamento de Atlántico; Colombia, se presentan las dimensiones que caracterizan lo artesanal. En ambas comunidades se elaboran máscaras en madera y artesanías en palma de iraca, respectivamente, las cuales han persistido a los retos de la globalización. Sin embargo, la capacidad de estos artesanos ha sido perturbada por la dinámica económica basada en el mercado, que les exige niveles de producción y utilización excesiva de recursos naturales, conduciéndolos a una ruptura entre el patrimonio cultural material, la memoria tecnológica y el balance ecológico de recursos naturales utilizados. El modelo se construye a partir de datos cualitativos obtenidos mediante instrumentos participativos sistematizados en una matriz de análisis estructural, para dar cuenta de las relaciones de incidencia y dependencia de las dimensiones del modelo. Los resultados se sintetizan en un instrumento que permite tomar decisiones sobre la productividad cultural, tecnológica y ecológica de la producción artesanal.An eco-technological model was used to determine aspects of artisanal production in the rural communities of Galapa and Usiacurí, located in the Department of Atlántico, Colombia. Galapa produces wooden masks and Usiacurí, handcrafts made with the Iraca palm. Both communities are facing the challenges of globalization and the capacity of their artisans has been affected by market economy dynamics, which demand high levels of production and excessive use of natural resources. This has led to a rupture between material cultural patrimony, technological memory, and ecological balance of natural resources used. The model draws from qualitative data obtained through participatory instruments, which are then systematized in a structural analysis matrix to determine the impact and inter-dependency of the different aspects covered in the

    We highlight the operational challenges and planned solutions faced by an optical observatory taking advantage of the superior astronomical observing potential of the Antarctic plateau. Unique operational aspects of an Antarctic optical observatory arise from its remoteness, the polar environment and the unusual observing cycle afforded by long continuous periods of darkness and daylight. PILOT is planned to be run with remote observing via satellite communications, and must overcome both limited physical access and data transfer. Commissioning and lifetime operations must deal with extended logistics chains, continual wintertime darkness, extremely low temperatures and frost accumulation amidst other challenging issues considered in the PILOT operational plan, and discussed in this presentation.

    We propose a quantitative network description on the function of uniqueness in a competition system. Two statistical parameters, competition ability and uniqueness are defined, and their relationship in ordinary cases is analytically discussed. The competition between Chinese regional universities is taken as an example. The empirical investigation results show that the uniqueness of a university is really important in competition. Also,uniqueness is very helpful in the promotion of the university overall quality.

  13. Psychological aspects of human cloning and genetic manipulation: the identity and uniqueness of human beings.

    Science.gov (United States)

    Morales, N M

    2009-01-01

    Human cloning has become one of the most controversial debates about reproduction in Western civilization. Human cloning represents asexual reproduction, but the critics of human cloning argue that the result of cloning is not a new individual who is genetically unique. There is also awareness in the scientific community, including the medical community, that human cloning and the creation of clones are inevitable. Psychology and other social sciences, together with the natural sciences, will need to find ways to help the healthcare system, to be prepared to face the new challenges introduced by the techniques of human cloning. One of those challenges is to help the healthcare system to find specific standards of behaviour that could be used to help potential parents to interact properly with cloned babies or children created through genetic manipulation. In this paper, the concepts of personality, identity and uniqueness are discussed in relationship to the contribution of twin studies in these areas. The author argues that an individual created by human cloning techniques or any other type of genetic manipulation will not show the donor's characteristics to the extent of compromising uniqueness. Therefore, claims to such an effect are needlessly alarmist.

    2017-01-03

    As a highly social species, humans are equipped with a powerful tool for social communication-the face. Although seemingly simple, the human face can elicit multiple social perceptions due to the rich variations of its movements, morphology, and complexion. Consequently, identifying precisely what face information elicits different social perceptions is a complex empirical challenge that has largely remained beyond the reach of traditional methods. In the past decade, the emerging field of social psychophysics has developed new methods to address this challenge, with the potential to transfer psychophysical laws of social perception to the digital economy via avatars and social robots. At this exciting juncture, it is timely to review these new methodological developments. In this article, we introduce and review the foundational methodological developments of social psychophysics, present work done in the past decade that has advanced understanding of the face as a tool for social communication, and discuss the major challenges that lie ahead.

  19. Multiple Face Location Using Motion Information

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Face location is a difficult problem for face recognition and multiple face location is more challenging. In this paper, two new methods are presented for multiple face location via motion analysis techniques. The first method is based on motion segmentation. The authors introduce a new segmentation method by computing optical flow only on the Motion Zero-Crossing Boundary (MZCB) followed by a simple clustering method to segment each person. Then an intuitive but effective location algorithm is applied to locate each face. The second method is derived from the Hough Transform (HT). After modeling a head outline as a curve consisting of circle segments, a modified HT is used to find the center of each face. Finally, the two methods are compared and the future research directions are given.

  20. Panel workload assessment in US primary care: accounting for non-face-to-face panel management activities.

    2014-01-01

    An understanding of primary care provider (PCP) workload is an important consideration in establishing optimal PCP panel size. However, no widely acceptable measure of PCP workload exists that incorporates the effort involved with both non-face-to-face patient care activities and face-to-face encounters. Accounting for this gap is critical given the increase in non-face-to-face PCP activities that has accompanied electronic health records (EHRs) (eg, electronic messaging). Our goal was to provide a comprehensive assessment of perceived PCP workload, accounting for aspects of both face-to-face and non-face-to-face encounters. Internal medicine, family medicine, and pediatric PCPs completed a self-administered survey about the perceived workload involved with face-to-face and non-face-to-face panel management activities as well as the perceived challenge associated with caring for patients with particular biomedical, demographic, and psychosocial characteristics (n = 185). Survey results were combined with EHR data at the individual patient and PCP service levels to assess PCP panel workload, accounting for face-to-face and non-face-to-face utilization. Of the multiple face-to-face and non-face-to-face activities associated with routine primary care, PCPs considered hospital admissions, obstetric care, hospital discharges, and new patient preventive health visits to be greater workload than non-face-to-face activities such as telephone calls, electronic communication, generating letters, and medication refills. Total workload within PCP panels at the individual patient level varied by overall health status, and the total workload of non-face-to-face panel management activities associated with routine primary care was greater than the total workload associated with face-to-face encounters regardless of health status. We used PCP survey results coupled with EHR data to assess PCP workload associated with both face-to-face as well as non-face-to-face panel management
