Adambekov, Shalkar; Kaiyrlykyzy, Aiym; Igissinov, Nurbek; Linkov, Faina

2016-01-01

The Central Asian region, which encompasses Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan and Kyrgyzstan, is an interesting geographic region with a rich history dating back to the Silk Road, Mongol conquests and expansion of the Russian Empire. However, from a public health viewpoint, the Central Asian region is under-investigated, and many public health challenges exist, as countries of Central Asia inherited the centralised medical systems practiced in the Soviet Union, and are currently undergoing rapid transitions. A large number of low and middle-income countries around the world, including countries of Central Asia, face a double burden of chronic and infectious disease. This essay focuses on the exploration of the most important public health challenges in the Central Asian region, including limited scientific productivity, the double burden of chronic and infectious disease, the need for healthcare reform and the reduction in care variation. Central Asia has a large number of medical schools, medical centres, and emerging research institutes that can be used to foster a change in medical and public health practice in the region.

Rainfall Induced Natural Disaster in Central America, a challenge for Regional Risk Management

NASA Astrophysics Data System (ADS)

Estuardo Guinea Barrientos, Héctor; Swain, Ashok

2013-04-01

Rainfall induced natural disasters rank first among all natural disasters in Central America. According to the records of the EM-DAT international database, 248 out of 486 disasters registered in Central America were disasters triggered by rainfall invents, in countries like Belize and Honduras, rainfall-induced natural disasters, mainly floods and landslides, account for more than 90% of the total number of casualties as well as the economic damage of all the disasters. Due to the natural conditions of the Central American Isthmus, precipitation events often struck more than one country at the time, for example Hurricane Mitch in 1998 affected the entire Central American region causing more than 18,000 casualties. In this context, the Central America countries have been working on joint programs and policies aiming transboundary cooperation and management of natural disasters, a clear example of this effort is CEPREDENAC which is the intergovernmental body with the mandate of promoting activities, projects and programs towards reduction of the risks to disasters in order to avoid loss of life and economic assets in the Central America, however, transnational management face several challenges that fall mostly in the political, economical and technical areas. In this paper we described and analyzed the rainfall induced natural disasters, their impacts and the inherent management challenges in the Central American context. Key words: Central America, Natural Disasters, Risk Management, International Cooperation

Facing Challenges in Differential Classical Conditioning Research: Benefits of a Hybrid Design for Simultaneous Electrodermal and Electroencephalographic Recording.

PubMed

Pastor, M Carmen; Rehbein, Maimu Alissa; Junghöfer, Markus; Poy, Rosario; López, Raul; Moltó, Javier

2015-01-01

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 psychophysiological measures.

Autonomic responses to exercise: where is central command?

PubMed

Williamson, J W

2015-03-01

A central command is thought to involve a signal arising in a central area of the brain eliciting a parallel activation of the autonomic nervous system and skeletal muscle contraction during exercise. Although much of the neural circuitry involved in autonomic control has been identified, defining the specific higher brain region(s) serving in a central command capacity has proven more challenging. Investigators have been faced with redundancies in regulatory systems, feedback mechanisms and the complexities ofhuman neural connectivity. Several studies have attempted to address these issues and provide more definitive neuroanatomical information. However, none have clearly answered the question, "where is central command?"

Addressing global change challenges for Central Asian socio-ecosystems

NASA Astrophysics Data System (ADS)

Qi, Jiaguo; Bobushev, Temirbek S.; Kulmatov, Rashid; Groisman, Pavel; Gutman, Garik

2012-06-01

Central Asia is one of the most vulnerable regions on the planet earth to global climate change, depending on very fragile natural resources. The Soviet legacy has left the five countries (Kazakhstan, Tajikistan, Kyrgyzstan, Turkmenistan, and Uzbekistan) with a highly integrated system but they are facing great challenges with tensions that hinder regional coordination of food and water resources. With increasing climate variability and warming trend in the region, food and water security issues become even more crucial now and, if not addressed properly, could affect the regional stability. The long-term drivers of these two most critical elements, food and water, are climate change; the immediate and probably more drastic factors affecting the food and water security are land uses driven by institutional change and economic incentives. As a feedback, changes in land use and land cover have directly implications on water uses, food production, and lifestyles of the rural community in the region. Regional and international efforts have been made to holistically understand the cause, extent, rate and societal implications of land use changes in the region. Much of these have been understood, or under investigation by various projects, but solutions or research effort to develop solutions, to these urgent regional issues are lacking. This article, serves as an introduction to the special issue, provides a brief overview of the challenges facing the Central Asian countries and various international efforts in place that resulted in the publications of this special issue.

New challenges for palliative nursing.

PubMed

Aranda, Sanchia

1997-05-02

Editorials by Jeanette Webber and Libby White (IJPN 2(3)) explored threats to both the nursing profession and palliative nursing as the health system faces the reality of limited resources and expanding client needs. I wish to pick up on these issues in the light of changes proposed for palliative care in one Australian state, Victoria. My central argument is that to secure the future of palliative nursing, efforts must focus on demonstrating clearly the value and contribution of nurses to client and family outcomes. Why do I think we are challenged to do this?

The negotiation and maintenance of professional boundaries is a central developmental challenge for medical students in clinical training. The purpose of this study is to assess problem solving strategies, decisions made, level of confidence, and language used by beginning third year medical students when faced with professional boundary challenges. Forty-two students in the first quarter of their third year at Harvard Medical School viewed three brief audiovisual "trigger" tapes, each depicting a medical student faced with a boundary challenge (the offer of a gift, a personal question from a patient, an errand request by a supervisor). There was a high degree of agreement and confidence among students about how to negotiate a monetary gift (reject) and how to respond to a patient's "too personal" question (not answer and/or redirect). However, the students were less confident and more divided on the issue of whether or not to run a personal errand for the team at the request of a superior. Our findings have implications for medical professionalism curricula, especially regarding the importance of mentorship and role modeling in medical education. Effective professional boundaries curricula allow the student to problem solve and practice communication skills in boundary challenging situations.

The Psychology of Working Theory.

2016-03-01

In the current article, we build on research from vocational psychology, multicultural psychology, intersectionality, and the sociology of work to construct an empirically testable Psychology of Working Theory (PWT). Our central aim is to explain the work experiences of all individuals, but particularly people near or in poverty, people who face discrimination and marginalization in their lives, and people facing challenging work-based transitions for which contextual factors are often the primary drivers of the ability to secure decent work. The concept of decent work is defined and positioned as the central variable within the theory. A series of propositions is offered concerning (a) contextual predictors of securing decent work, (b) psychological and economic mediators and moderators of these relations, and (c) outcomes of securing decent work. Recommendations are suggested for researchers seeking to use the theory and practical implications are offered concerning counseling, advocacy, and public policy. (c) 2016 APA, all rights reserved).

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.

The role of external features in face recognition with central vision loss: A pilot study

PubMed Central

Bernard, Jean-Baptiste; Chung, Susana T.L.

2016-01-01

Purpose We evaluated how the performance for recognizing familiar face images depends on the internal (eyebrows, eyes, nose, mouth) and external face features (chin, outline of face, hairline) in individuals with central vision loss. Methods In Experiment 1, we measured eye movements for four observers with central vision loss to determine whether they fixated more often on the internal or the external features of face images while attempting to recognize the images. We then measured the accuracy for recognizing face images that contained only the internal, only the external, or both internal and external features (Experiment 2), and for hybrid images where the internal and external features came from two different source images (Experiment 3), for five observers with central vision loss and four age-matched control observers. Results When recognizing familiar face images, approximately 40% of the fixations of observers with central vision loss were centered on the external features of faces. The recognition accuracy was higher for images containing only external features (66.8±3.3% correct) than for images containing only internal features (35.8±15.0%), a finding contradicting that of control observers. For hybrid face images, observers with central vision loss responded more accurately to the external features (50.4±17.8%) than to the internal features (9.3±4.9%), while control observers did not show the same bias toward responding to the external features. Conclusions Contrary to people with normal vision who rely more on the internal features of face images for recognizing familiar faces, individuals with central vision loss show a higher dependence on using external features of face images.

Groundwater is an increasingly important source of freshwater, especially where surface water resources are fully or over-allocated or becoming less reliable due to climate change. Groundwater reliance has created new challenges for sustainable management. This article examines how regional groundwater users coordinate and collaborate to manage shared groundwater resources, including attention to what drives collaboration. To identify and illustrate these facets, this article examines three geographically diverse cases of groundwater governance and management from the United States Sun Belt: Orange County Water District in southern California; Prescott Active Management Area in north-central Arizona; and the Central Florida Water Initiative in central Florida. These regions have different surface water laws, groundwater allocation and management laws and regulations, demographics, economics, topographies, and climate. These cases were selected because the Sun Belt faces similar pressures on groundwater due to historical and projected population growth and limited availability of usable surface water supplies. Collectively, they demonstrate groundwater governance trends in the United States, and illustrate distinctive features of regional groundwater management strategies. Our research shows how geophysical realities and state-level legislation have enabled and/or stimulated regions to develop groundwater management plans and strategies to address the specific issues associated with their groundwater resources. We find that litigation involvement and avoidance, along with the need to finance projects, are additional drivers of regional collaboration to manage groundwater. This case study underscores the importance of regionally coordinated and sustained efforts to address serious groundwater utilization challenges faced by the regions studied and around the world.

The political economy of noncompliance in China: The case of industrial energy policy

2015-03-18

One of the greatest challenges facing China today is the central government's ability to ensure that policies are implemented effectively at the local level, particularly policies that seek to make China's economic growth model more sustainable. These policies face resistance from local authorities and enterprises that benefit from the status quo. This raises a key research question: why do some provinces more fully implement these central policies? We argue the extent of local implementation is best conceptualized as a rational balance between economic and political incentives: localities with regulatory autonomy, low regulatory capacity and alternative interests will not fully implementmore » policies that are at odds with local economic imperatives. By examining a critical case of central policy implementation—industrial energy intensity reduction in the eleventh five-year plan—this article demonstrates that, regardless of industrial makeup or economic development, provinces that have greater regulatory autonomy for noncompliance coupled with alternative economic interests do not, on average, perform as well. As a result, using a nested analysis approach this study illustrates this argument with both quantitative analysis and original case study evidence from fieldwork interviews.« less

The Central Command for Maritime Emergencies was founded in Germany in 2003 triggered by the fire on board of the cargo ship "Pallas" in 1998. Its mission is to coordinate and direct measures at or above state level in maritime emergency situations in the North Sea and the Baltic Sea. A special task in this case is to provide firefighting and medical care. To face these challenges at sea emergency doctors and firemen have been specially trained. This form of organization provides a concept to counter mass casualty incidents and peril situations at sea. Since the foundation of the Central Command for Maritime Emergencies there have been 5 operations for firefighting units and 4 for medical response teams. Assignments and structure of the Central Command for Maritime Emergencies are unique in Europe.

The role of the amygdala and the basal ganglia in visual processing of central vs. peripheral emotional content.

PubMed

Almeida, Inês; van Asselen, Marieke; Castelo-Branco, Miguel

2013-09-01

In human cognition, most relevant stimuli, such as faces, are processed in central vision. However, it is widely believed that recognition of relevant stimuli (e.g. threatening animal faces) at peripheral locations is also important due to their survival value. Moreover, task instructions have been shown to modulate brain regions involved in threat recognition (e.g. the amygdala). In this respect it is also controversial whether tasks requiring explicit focus on stimulus threat content vs. implicit processing differently engage primitive subcortical structures involved in emotional appraisal. Here we have addressed the role of central vs. peripheral processing in the human amygdala using animal threatening vs. non-threatening face stimuli. First, a simple animal face recognition task with threatening and non-threatening animal faces, as well as non-face control stimuli, was employed in naïve subjects (implicit task). A subsequent task was then performed with the same stimulus categories (but different stimuli) in which subjects were told to explicitly detect threat signals. We found lateralized amygdala responses both to the spatial location of stimuli and to the threatening content of faces depending on the task performed: the right amygdala showed increased responses to central compared to left presented stimuli specifically during the threat detection task, while the left amygdala was better prone to discriminate threatening faces from non-facial displays during the animal face recognition task. Additionally, the right amygdala responded to faces during the threat detection task but only when centrally presented. Moreover, we have found no evidence for superior responses of the amygdala to peripheral stimuli. Importantly, we have found that striatal regions activate differentially depending on peripheral vs. central processing of threatening faces. Accordingly, peripheral processing of these stimuli activated more strongly the putaminal region, while central processing engaged mainly the caudate nucleus. We conclude that the human amygdala has a central bias for face stimuli, and that visual processing recruits different striatal regions, putaminal or caudate based, depending on the task and on whether peripheral or central visual processing is involved. © 2013 Elsevier Ltd.

Over the past 5 years, using European and North American biobanks as models, the grass-roots establishment of independently operating biobanks has occurred virtually simultaneously in large Israeli teaching hospitals. The process of establishing a national biorepository network in Israel has progressed slowly, sustained mainly by a few proponents working together on a personal level. Slow progress has been due to limited funding and the lack of a legal framework specific to biobanking activities. Recently, due to increasing pressure from the scientific community, the government has earmarked funds for a national biorepository network, and the structure is now being established. In forming a network, Israel's biobanks face certain difficulties, particularly lack of support. Additional challenges include harmonization of standard operating procedures, database centralization, and use of a common informed consent form. In this article, we highlight some of the issues faced by Israel's biobank managers in establishing and sustaining a functional biobank network, information that could provide guidance for other small countries with limited resources.

Meanings, Mechanisms, and Measures of Holistic Processing

PubMed Central

Richler, Jennifer J.; Palmeri, Thomas J.; Gauthier, Isabel

2012-01-01

Few concepts are more central to the study of face recognition than holistic processing. Progress toward understanding holistic processing is challenging because the term “holistic” has many meanings, with different researchers addressing different mechanisms and favoring different measures. While in principle the use of different measures should provide converging evidence for a common theoretical construct, convergence has been slow to emerge. We explore why this is the case. One challenge is that “holistic processing” is often used to describe both a theoretical construct and a measured effect, which may not have a one-to-one mapping. Progress requires more than greater precision in terminology regarding different measures of holistic processing or different hypothesized mechanisms of holistic processing. Researchers also need to be explicit about what meaning of holistic processing they are investigating so that it is clear whether different researchers are describing the same phenomenon or not. Face recognition differs from object recognition, and not all meanings of holistic processing are equally suited to help us understand that important difference. PMID:23248611

Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures. The Commission on Social Determinants of Health (2005-2008) strengthened the case for SPHs in LMICs as key stakeholders in efforts to reduce global health inequities. This scoping review groups text into public health challenges faced by LMICs and the role of SPHs in addressing these challenges. The challenges faced by LMICs include rapid urbanization, environmental degradation, unfair terms of global trade, limited capacity for equitable growth, mass displacements associated with conflicts and natural disasters, and universal health coverage. Poor governance and externally imposed donor policies and agendas, further strain the fragile health systems of LMICs faced with epidemiological transition. Moreover barriers to education and research imposed by limited resources, political and economic instability, and unbalanced partnerships additionally aggravate the crisis. To address these contextual challenges effectively, SPHs are offering broad based health professional education, conducting multidisciplinary population based research and fostering collaborative partnerships. SPHs are also looked upon as the key drivers to achieve sustainable development goals (SDGs). SPHs in LMICs can contribute to overcoming several public health challenges being faced by LMICs, including achieving SDGs. Most importantly they can develop cadres of competent and well-motivated public health professionals: educators, practitioners and researchers who ask questions that address fundamental health determinants, seek solutions as agents of change within their mandates, provide specific services and serve as advocates for multilevel partnerships. Funding support, human resources, and agency are unfortunately often limited or curtailed in LMICs, and this requires constructive collaboration between LMICs and counterpart institutions from high income countries.

Decentralized approaches to wastewater treatment and management: applicability in developing countries.

PubMed

Massoud, May A; Tarhini, Akram; Nasr, Joumana A

2009-01-01

Providing reliable and affordable wastewater treatment in rural areas is a challenge in many parts of the world, particularly in developing countries. The problems and limitations of the centralized approaches for wastewater treatment are progressively surfacing. Centralized wastewater collection and treatment systems are costly to build and operate, especially in areas with low population densities and dispersed households. Developing countries lack both the funding to construct centralized facilities and the technical expertise to manage and operate them. Alternatively, the decentralized approach for wastewater treatment which employs a combination of onsite and/or cluster systems is gaining more attention. Such an approach allows for flexibility in management, and simple as well as complex technologies are available. The decentralized system is not only a long-term solution for small communities but is more reliable and cost effective. This paper presents a review of the various decentralized approaches to wastewater treatment and management. A discussion as to their applicability in developing countries, primarily in rural areas, and challenges faced is emphasized all through the paper. While there are many impediments and challenges towards wastewater management in developing countries, these can be overcome by suitable planning and policy implementation. Understanding the receiving environment is crucial for technology selection and should be accomplished by conducting a comprehensive site evaluation process. Centralized management of the decentralized wastewater treatment systems is essential to ensure they are inspected and maintained regularly. Management strategies should be site specific accounting for social, cultural, environmental and economic conditions in the target area.

The "Batman flap": a novel technique to repair a large central glabellar defect.

PubMed

Puviani, Mario; Curci, Marco

2018-04-01

Given the critical position of central glabella among the frontal, nasal, and supraorbital aesthetic subunits of the face, the reconstruction of large defects in this area represents a surgical challenge. We describe a surgical technique based on a modified, curved, A-T flap to repair a large glabellar defect. Our modification is useful for large glabellar defects because it enables the distribution of the tension all over the reconstruction sides, avoiding a stressed central area and the subsequent risk of necrosis; functionally, it respects the eyebrows position and since the advancement is parallel to their major axes, it avoids the reduction of the distance between them. The "Batman flap" enables reconstructing a glabellar defect, with a good aesthetical result and the respect of the relevant aesthetical subunits. © 2017 The International Society of Dermatology.

Studies are needed to inform the preparation of community nurses to address patient behavioral and social factors contributing to unnecessary readmissions to hospital. This study uses nurses' input to understand challenges faced during home care, to derive a framework to address the challenges. Semistructured interviews were conducted to saturation with 16 community nurses in Singapore. Interviews were transcribed verbatim and transcripts independently coded for emergent themes. Themes were interpreted using grounded theory. Seven major themes emerged from 16 interviews: Strained social relationships, complex care decision-making processes within families, communication barriers, patient's or caregiver neglect of health issues, building and maintaining trust, trial-and-error nature of work, and dealing with uncertainty. Community nurses identified uncertainty arising from complexities in social-relational, personal, and organizational factors as a central challenge. Nursing education should focus on navigating and managing uncertainty at the personal, patient, and family levels.

Mapping Multiplex Hubs in Human Functional Brain Networks

PubMed Central

De Domenico, Manlio; Sasai, Shuntaro; Arenas, Alex

2016-01-01

Typical brain networks consist of many peripheral regions and a few highly central ones, i.e., hubs, playing key functional roles in cerebral inter-regional interactions. Studies have shown that networks, obtained from the analysis of specific frequency components of brain activity, present peculiar architectures with unique profiles of region centrality. However, the identification of hubs in networks built from different frequency bands simultaneously is still a challenging problem, remaining largely unexplored. Here we identify each frequency component with one layer of a multiplex network and face this challenge by exploiting the recent advances in the analysis of multiplex topologies. First, we show that each frequency band carries unique topological information, fundamental to accurately model brain functional networks. We then demonstrate that hubs in the multiplex network, in general different from those ones obtained after discarding or aggregating the measured signals as usual, provide a more accurate map of brain's most important functional regions, allowing to distinguish between healthy and schizophrenic populations better than conventional network approaches.

2015-01-01

Summary While Principlism is a widely accepted consensus statement for ethics, the moral theory that underpins it faces serious challenges. This two-part paper proposes a version of virtue theory as a more grounded system of moral analysis. Part 2 examines the role of basic moral theory as the foundation to ethics and suggests how virtue theory can be used as a central framework for ethics while being inclusive of insights from deontology and consequentialism.

Challenges for nursing education in Angola: the perception of nurse leaders affiliated with professional education institutions

PubMed Central

2013-01-01

Background Angola is one of the African countries with the highest morbidity and mortality rates and a devastating lack of human resources for health, including nursing. The World Health Organization stimulates and takes technical cooperation initiatives for human resource education and training in health and education, with a view to the development of countries in the region. The aim in this study was to identify how nurses affiliated with nursing education institutions perceive the challenges nursing education is facing in Angola. Methods After consulting the National Directory of Human Resources in Angola, the nurse leaders affiliated with professional nursing education institutions in Angola were invited to participate in the study by email. Data were collected in February 2009 through the focus group technique. The group of participants was focused on the central question: what are the challenges faced for nursing education in your country? To register and understand the information, besides the use of a recorder, the reporters elaborated an interpretative report. Data were coded using content analysis. Results Fourteen nurses participated in the meeting, most of whom were affiliated with technical nursing education institutions. It was verified that the nurse leaders at technical and higher nursing education institutions in Angola face many challenges, mainly related to the lack of infrastructure, absence of trained human resources, bureaucratic problems to regularize the schools and lack of material resources. On the opposite, the solutions they present are predominantly centered on the valuation of nursing professionals, which implies cultural and attitude changes. Conclusions Public health education policies need to be established in Angola, including action guidelines that permit effective nursing activities. Professional education institutions need further regularizations and nurses need to be acknowledged as key elements for the qualitative enhancement of health services in the country. PMID:23866740

The aim of this report is to describe the challenges, successes and patterns of enrolment in the Strategic Timing of AntiRetroviral Treatment (START) study. START is a collaboration of many partners with central coordination provided by the protocol team, the statistical and data management centre (SDMC), the International Network for Strategic Initiatives in Global HIV Trials (INSIGHT) network leadership, international coordinating centres and site coordinating centres. The SDMC prepared reports on study accrual, baseline characteristics and site performance that allowed monitoring of enrolment and data quality and helped to ensure the successful enrolment of this large international trial. We describe the pattern of enrolment and challenges faced during the enrolment period of the trial. An initial pilot phase began in April 2009 and established feasibility of accrual at 101 sites. In August 2010, funding approval for an expanded definitive phase led to the successful accrual of 4688 participants from 215 sites in 35 countries by December 2013. Challenges to accrual included regulatory delays (e.g. national/local ethics approval and drug importation approval) and logistical obstacles (e.g. execution of contracts with pharmaceutical companies, setting up of a central drug repository and translation of participant materials). The personal engagement of investigators, strong central study coordination, and frequent and transparent communication with site investigators, community members and participants were key contributing factors to this success. Accrual into START was completed in a timely fashion despite multiple challenges. This success was attributable to the efforts of site investigators committed to maintaining study equipoise, transparent and responsive study coordination, and community involvement in problem-solving. © 2015 British HIV Association.

The role of farming and rural development as central to our diets.

PubMed

Fanzo, Jessica

2018-05-21

Farming and rural development are central to the diversity of global food systems and diets, both significant factors in determining the nutrition and health outcomes of the world's population. Diets are not static and indeed are changing due to globalization, urbanization and demographic shifts. In addition, multiple burdens of malnutrition (both undernutrition and overweight and obesity) are not improving fast enough and in some cases, reversing for the worse. Unhealthy diets are major contributors to these burdens. Rural people and particularly smallholder farmers, are critical in delivering the key nutrients in the global food supply that make up our diets for human health. However, rural populations in some parts of the world are often poor, and suffer burdens of malnutrition on both ends of the spectrum - undernourished or overweight. They are also faced with significant challenges, often due to poor investment towards rural development. Challenges include natural resource declines, climate change risk, women disempowerment, conflict, and urbanization; which wreak havoc on these populations. If actions are not taken and their livelihoods are not prioritized, it will be a challenge to achieve sustainable development in these rural places that are so essential for future food systems.

The Human Face as a Dynamic Tool for Social Communication.

PubMed

Jack, Rachael E; Schyns, Philippe G

2015-07-20

As a highly social species, humans frequently exchange social information to support almost all facets of life. One of the richest and most powerful tools in social communication is the face, from which observers can quickly and easily make a number of inferences - about identity, gender, sex, age, race, ethnicity, sexual orientation, physical health, attractiveness, emotional state, personality traits, pain or physical pleasure, deception, and even social status. With the advent of the digital economy, increasing globalization and cultural integration, understanding precisely which face information supports social communication and which produces misunderstanding is central to the evolving needs of modern society (for example, in the design of socially interactive digital avatars and companion robots). Doing so is challenging, however, because the face can be thought of as comprising a high-dimensional, dynamic information space, and this impacts cognitive science and neuroimaging, and their broader applications in the digital economy. New opportunities to address this challenge are arising from the development of new methods and technologies, coupled with the emergence of a modern scientific culture that embraces cross-disciplinary approaches. Here, we briefly review one such approach that combines state-of-the-art computer graphics, psychophysics and vision science, cultural psychology and social cognition, and highlight the main knowledge advances it has generated. In the light of current developments, we provide a vision of the future directions in the field of human facial communication within and across cultures. Copyright © 2015 Elsevier Ltd.

A study was performed to examine the correlation between maxillary central incisor tooth form and face form in males and females in an Indian population. The selection of prosthetic teeth for edentulous patients is a primary issue in denture esthetics, especially in the case of maxillary central incisors, which are the most prominent teeth in the arch. Two hundred dental students of Indian origin comprising 79 males and 121 females aged 18-28 years studying at Bapuji Dental College and Hospital were randomly selected as the study subjects. A standardized photographic procedure was used to obtain images of the face and the maxillary central incisors. The outline forms of the face and the maxillary right central incisor tooth were determined using a standardized method. The outline forms obtained were used to classify both face form and tooth form on the basis of visual and William's methods. The means were considered after evaluation by five prosthodontists, and the results were tabulated. Statistical analysis was performed using the chi-squared test for association and Z-test for equality of proportions. A correlation greater than 50% was observed between tooth form and face form by the visual method, compared with one of 31.5% by William's method. There was no highly defined correlation between maxillary central incisor tooth form and face form among the male and female Indian subjects studied.

Moving to a Soft Path for Water: Integrated Research and Management Needs

NASA Astrophysics Data System (ADS)

Gleick, P. H.

2011-12-01

Water on Earth in its three fundamental phases is integral to the functioning, dynamics, and variability of the global climatological and biological support systems. From a purely scientific point of view, understanding the complexity of the hydrological cycle is of paramount interest and central to our understanding of other planetary geological, atmospheric, chemical, and physical processes. But water is more than that: water is key to economic, social, and political issues as well, including some of the core challenges of our time such central to issues of poverty, health, environmental sustainability, conflict, and economic prosperity. The more society seeks to solve these challenges, the more obvious it becomes that we must improve more than just our understanding of the fundamental science of the hydrological cycle and its links with related global processes; we must also improve our understanding of the complex social, economic, and structural challenges facing water managers and users. We must move to a different paradigm where water is managed in a far more integrated way - what I call the "soft path for water." Central to our basic science needs are (1) an expansion of the frequency and nature of the data we collect, (2) the development of systems for managing, sharing, and analyzing those data, and (3) improvements in our ability to model and forecast the hydrological cycle together with other climatological, geophysical, and biochemical systems. These improvements would lead to a far better understanding of the local, regional, and global details of the water balance on timescales from minutes to millennia. These needs are increasingly well understood in the research community and extensive efforts in these areas are underway under the auspices of national research centers, universities, and international scientific collaborations. But it is also becoming increasingly apparent that many of the current water challenges facing society are not going to be resolved solely through improvements in scientific understanding. Many water challenges lie at the intersection between pure science and applied science, or between the sciences and economics and policy. Any effort to summarize future needs must therefore also acknowledge the urgent need to improve our understanding of how humans are increasingly influencing and changing the hydrologic cycle and the ultimate consequences of those changes for societal well-being. Such efforts would be greatly enhanced by interdisciplinary research and policy efforts involving the scientific community and a broader range of engineers, economists, utility managers, irrigators, and local communities. For example, as one measure of the recognition of these challenges, the Hydrology Section of the American Geophysical Union has just constituted a new Technical Committee on Water and Society to broaden the issues addressed by AGU members and to develop alternative paths - including "soft paths" to addressing a wide range of water-related challenges.

Meeting the increasing demand for clean, affordable, and secure energy is arguably the most important challenge facing the world today. Fossil fuels can play a central role in a portfolio of carbon-neutral energy options provided CO{sub 2} emissions can be dramatically reduced by capturing CO{sub 2} and storing it safely and effectively. Fossil energy industry faces the challenge of meeting aggressive design goals for next-generation power plants with CCS. Process designs will involve large, highly-integrated, and multipurpose systems with advanced equipment items with complex geometries and multiphysics. APECS is enabling software to facilitate effective integration, solution, and analysis of high-fidelitymore » process/equipment (CFD) co-simulations. APECS helps to optimize fluid flow and related phenomena that impact overall power plant performance. APECS offers many advanced capabilities including ROMs, design optimization, parallel execution, stochastic analysis, and virtual plant co-simulations. NETL and its collaborative R&D partners are using APECS to reduce the time, cost, and technical risk of developing high-efficiency, zero-emission power plants with CCS.« less

Social change or business as usual at city hall? Examining an urban municipal government's response to neighbourhood-level health inequities.

Cahuas, Madelaine C; Wakefield, Sarah; Peng, Yun

2015-05-01

There is a renewed interest in the potential of municipal governments working collaboratively with local communities to address health inequities. A growing body of literature has also highlighted the benefits and limitations of participatory approaches in neighbourhood interventions initiated by municipal governments. However, few studies have investigated how neighbourhood interventions tackling health inequities work in real-time and in context, from the perspectives of Community Developers (CDs) who promote community participation. This study uses a process evaluation approach and semi-structured interviews with CDs to explore the challenges they face in implementing a community development, participatory process in the City of Hamilton's strategy to reduce health inequities - Neighbourhood Action. Findings demonstrate that municipal government can facilitate and suppress community participation in complex ways. CDs serve as significant but conflicted intermediaries as they negotiate and navigate power differentials between city and community actors, while also facing structural challenges. We conclude that community participation is important to bottom-up, resident-led social change, and that CDs are central to this work. Copyright © 2014 Elsevier Ltd. All rights reserved.

Central Appalachia residents present unique healthcare challenges. This vulnerable population faces poor health status and low access to health care. 'The Health Wagon' was established to innovatively enhance access to health care for the poor and marginalized rural population of Central Appalachia. This article describes the operations of the Health Wagon, a full mobile medical clinic, in delivering free health care to those in rural Southwest Virginia in Central Appalachia. The Health Wagon provides a wide range of comprehensive healthcare services, such as acute and chronic disease management, laboratory and diagnostic services, medication assistance, dental and eye care and specialty clinics for marginalized, poor and disenfranchised patients living in the mountains of that region. In 2009, a total of 157 clinics were provided and 2900 patients were seen (3165 patient encounters) in addition to 268 telemedicine specialty consultations at no cost to the patients. The work of the Health Wagon has broken down a financial barrier to healthcare access and offers unique and profound opportunities to improve health and expand health care in rural Central Appalachia.

In 1996, Jim Allison demonstrated that blocking the immune regulatory molecule CTLA-4 with anit-CTLA4 antibody led to enhance tumor responses in mice. It would take an additional 15 years for human studies to confirm the potency and clinical efficacy of anti-CTLA4, ultimately leading to US FDA approval of the first checkpoint inhibitor, ipilimumab. Now with a plethora of immune-modulating agents demonstrating single agent safety and benefit across many tumor types, investigation on the optimal combination of immune-based therapies has begun in earnest. While there are many challenges, a central one is how to select which combination for which patient is the best. Here we review the current approaches that a practitioner can use to achieve this therapeutic goal.

Sustainability appraisals produce evidence for how well water governance regimes operate and where problems exist. This evidence is particularly relevant for regions that face water scarcity and conflicts. In this study, we present a criteria-based and participatory sustainability appraisal of water governance in a region with such characteristics-the dry tropics of NW Costa Rica. Data collection included 47 interviews and three stakeholder workshops. The appraisal was conducted through a collaborative and iterative process between researchers and stakeholders. Out of the 25 sustainability criteria used, seven posed a significant challenge for the governance regime. We found challenges faced by the governance regime primarily clustered around and were re-enforced by failing coordination related to the use, management, and protection of groundwater resources; and inadequate leadership to identify collective goals and to constructively deliberate alternative ways of governing water with diverse groups. The appraisal yielded some positive impact in the study area, yet we found its application provided only limited strategic information to support broader problem-solving efforts. Insights from this study suggest key starting points for sustainable water governance in the Central American dry tropics, including investing in increasingly influential collective organizations that are already active in water governance; and leveraging policy windows that can be used to build confidence and disperse more governing authority to regional and local governing actors that are in-tune with the challenges faced in the dry tropics. We conclude the article with reflections on how to produce research results that are actionable for sustainable water governance.

The recent development of ultra-high intensity laser facilities is finally opening up the possibility of studying high-field quantum electrodynamics in the laboratory. Arguably, one of the central phenomena in this area is that of quantum radiation reaction experienced by an ultra-relativistic electron beam as it propagates through the tight focus of a laser beam. In this paper, we discuss the major experimental challenges that are to be faced in order to extract meaningful and quantitative information from this class of experiments using existing and near-term laser facilities.

Today, 24-hour operations are necessary to meet the demands of our society and the requirements of our industrialized global economy. These around-the-clock demands pose unique physiological challenges for the humans who remain central to safe and productive operations. Optimal alertness and performance are critical factors that are increasingly challenged by unusual, extended, or changing work/rest schedules. Technological advancements and automated systems can exacerbate the challenges faced by the human factor in these environments. Shift work, transportation demands, and continuous operations engender sleep loss and circadian disruption. Both of these physiological factors can lead to increased sleepiness, decreased performance, and a reduced margin of safety. These factors can increase vulnerability to incidents and accidents in operational settings. The consequences can have both societal effects (e.g., major destructive accidents such as Three Mile Island, Exxon Valdez, Bhopal) and personal effects (e.g., an accident driving home after a night shift).

Individuals who are Deaf face challenges both similar and unique from those faced by hearing individuals when a family member is dying. This study was guided by the question “What are the challenges faced by a Deaf family member when a loved one is dying?” Methods - This qualitative study is guided by critical theory and an interpretive perspective. Robert, a college-educated older adult who has been Deaf from birth was interviewed in American Sign Language using a death history format. Results – There are challenges for Deaf family members that affect communication with both the dying person and health care professionals. Patient-family communication issues included physical challenges and financial challenges. Lack of cultural competence concerning the Deaf community created challenges communicating with professionals. Decision-making was also a challenge. Conclusions These findings provide a framework for future research concerning the needs of Deaf individuals facing the end of life and provide guidance for clinicians. PMID:19910395

Re-Thinking the Role of the Family in Medical Decision-Making.

PubMed

Cherry, Mark J

2015-08-01

This paper challenges the foundational claim that the human family is no more than a social construction. It advances the position that the family is a central category of experience, being, and knowledge. Throughout, the analysis argues for the centrality of the family for human flourishing and, consequently, for the importance of sustaining (or reestablishing) family-oriented practices within social policy, such as more family-oriented approaches to consent to medical treatment. Where individually oriented approaches to medical decision-making accent an ethos of isolated personal autonomy family-oriented approaches acknowledge the central social and moral reality of the family. I argue that the family ought to be appreciated as more than a mere network of personal relations and individual undertakings; the family possesses a being that is social and moral such that it realizes a particular structure of human good and sustains the necessary conditions for core areas of human flourishing. Moreover, since the family exists as a nexus of face-to-face relationships, the consent of persons, including adults, to be members of a particular family, subject to its own respective account of family sovereignty, is significantly more amply demonstrated than the consent of citizens to be under the authority of a particular state. As a result, in the face of a general Western bioethical affirmation of the autonomy of individuals, as if adults and children were morally and socially isolated agents, this paper argues that social space must nevertheless be made for families to choose on behalf of their own members. © The Author 2015.

To explore nurses' challenges in managing pain among ill patients in critical care. Pain can lead to many adverse medical consequences and providing pain relief is central to caring for ill patients. Effective pain management is vital since studies show patients admitted to critical care units still suffer from significant levels of acute pain. The effective delivery of care in clinical areas remains a challenge for nurses involved with care which is dynamic and constantly changing in critically ill. Qualitative prospective exploratory design. This study employed semi structured interviews with nurses, using critical incident technique. Twenty-one nurses were selected from critical care settings from a large acute teaching health care trust in the UK. A critical incident interview guide was constructed from the literature and used to elicit responses. Framework analysis showed that nurses perceived four main challenges in managing pain namely lack of clinical guidelines, lack of structured pain assessment tool, limited autonomy in decision making and the patient's condition itself. Nurses' decision making and pain management can influence the quality of care given to critically ill patients. It is important to overcome the clinical problems that are faced when dealing with pain experience. There is a need for nursing education on pain management. Providing up to date and practical strategies may help to reduce nurses' challenges in managing pain among critically ill patients. Broader autonomy and effective decision making can be seen as beneficial for the nurses besides having a clearer and structured pain management guidelines. © 2011 Blackwell Publishing Ltd.

The Global Initiative for Cancer Registry Development partnership, led by the International Agency for Research on Cancer (IARC), was established in response to an overwhelming need for high-quality cancer incidence data from low-income and middle-income countries. The IARC Regional Hub for cancer registration in North Africa, Central and West Asia was founded in 2013 to support capacity building for cancer registration in each of the countries in this region. In this Series paper, we advocate the necessity for tailored approaches to cancer registration given the rapidly changing cancer landscape for this region, and the challenges faced at a national level in developing data systems to help support this process given present disparities in resources and health infrastructure. In addition, we provide an overview of the status of cancer surveillance and activities country-by-country, documenting tailored approaches that are informing local cancer-control policy, and potentially curbing the growing cancer burden across the region.

Phytoextraction has a promising potential as an environmentally friendly clean-up method for soils contaminated with toxic metals. To improve the development of efficient phytoextraction strategies, better knowledge regarding metal uptake, translocation and detoxification in planta is a prerequisite. This review highlights our current understanding on these mechanisms, and their impact on plant growth and health. Special attention is paid to the central role of glutathione (GSH) in this process. Because of the high affinity of metals to thiols and as a precursor for phytochelatins (PCs), GSH is an essential metal chelator. Being an important antioxidant, a direct link between metal detoxification and the oxidative challenge in plants growing on contaminated soils is observed, where GSH could be a key player. In addition, as redox couple, oxidized and reduced GSH transmits specific information, in this way tuning cellular signalling pathways under environmental stress conditions. Possible improvements of phytoextraction could be achieved by using transgenic plants or plant-associated microorganisms. Joined efforts should be made to cope with the challenges faced with phytoextraction in order to successfully implement this technique in the field. © 2011 Blackwell Publishing Ltd.

Spatial-frequency cutoff requirements for pattern recognition in central and peripheral vision

PubMed Central

Kwon, MiYoung; Legge, Gordon E.

2011-01-01

It is well known that object recognition requires spatial frequencies exceeding some critical cutoff value. People with central scotomas who rely on peripheral vision have substantial difficulty with reading and face recognition. Deficiencies of pattern recognition in peripheral vision, might result in higher cutoff requirements, and may contribute to the functional problems of people with central-field loss. Here we asked about differences in spatial-cutoff requirements in central and peripheral vision for letter and face recognition. The stimuli were the 26 letters of the English alphabet and 26 celebrity faces. Each image was blurred using a low-pass filter in the spatial frequency domain. Critical cutoffs (defined as the minimum low-pass filter cutoff yielding 80% accuracy) were obtained by measuring recognition accuracy as a function of cutoff (in cycles per object). Our data showed that critical cutoffs increased from central to peripheral vision by 20% for letter recognition and by 50% for face recognition. We asked whether these differences could be accounted for by central/peripheral differences in the contrast sensitivity function (CSF). We addressed this question by implementing an ideal-observer model which incorporates empirical CSF measurements and tested the model on letter and face recognition. The success of the model indicates that central/peripheral differences in the cutoff requirements for letter and face recognition can be accounted for by the information content of the stimulus limited by the shape of the human CSF, combined with a source of internal noise and followed by an optimal decision rule.

It is well known that facial beauty is dictated by facial type, and harmony between the eyes, nose, and mouth. Furthermore, facial impression is judged according to the overall facial contour and the relationship between the facial structures. The aims of the present study were to determine the optimal criteria for the assessment of gathering or separation of the facial structures and to define standardized ratios for centralization or decentralization of the facial structures.Four different lengths were measured, and 2 indexes were calculated from standardized photographs of 551 volunteers. Centralization and decentralization were assessed using the width index (interpupillary distance / facial width) and height index (eyes-mouth distance / facial height). The mean ranges of the width index and height index were 42.0 to 45.0 and 36.0 to 39.0, respectively. The width index did not differ with sex, but males had more decentralized faces, and females had more centralized faces, vertically. The incidence rate of decentralized faces among the men was 30.3%, and that of centralized faces among the women was 25.2%.The mean ranges in width and height indexes have been determined in a Korean population. Faces with width and height index scores under and over the median ranges are determined to be "centralized" and "decentralized," respectively.

In 1856, an appeal went out to nurses in both England and Ireland, and especially to religious nurses, to care for the troops fighting in the Crimean War. The Sisters of Mercy, founded in 1831 by Venerable Catherine McAuley, answered that call. This article describes the enormous challenges the Sisters faced in that mission, which was a test of their nursing skills, flexibility, organizational ability, and their spirit of mercy. The challenges they faced professionally and as religious Sisters, the manner in which they faced those challenges, and their spiritual lives as religious women shaped their ability to give comprehensive care. Some applications are made to the challenges which religious communities and organizations working in health care face in our country at this time. Summary: This article describes the challenges faced by a group of Sisters of Mercy from England and Ireland who volunteered to serve as nurses in the Crimean War from 1856 to 1858. Applications are made to challenges which are faced by religious communities and organizations in the current secular healthcare environment. PMID:28392597

An optical power splitter for the distribution of high-power light energy has a plurality of prisms arranged about a central axis to form a central channel. The input faces of the prisms are in a common plane which is substantially perpendicular to the central axis. A beam of light which is substantially coaxial to the central axis is incident on the prisms and at least partially strikes a surface area of each prism input face. The incident beam also partially passes through the central channel.

Dynamic Eye Tracking Based Metrics for Infant Gaze Patterns in the Face-Distractor Competition Paradigm

Objective To develop new standardized eye tracking based measures and metrics for infants’ gaze dynamics in the face-distractor competition paradigm. Method Eye tracking data were collected from two samples of healthy 7-month-old (total n = 45), as well as one sample of 5-month-old infants (n = 22) in a paradigm with a picture of a face or a non-face pattern as a central stimulus, and a geometric shape as a lateral stimulus. The data were analyzed by using conventional measures of infants’ initial disengagement from the central to the lateral stimulus (i.e., saccadic reaction time and probability) and, additionally, novel measures reflecting infants gaze dynamics after the initial disengagement (i.e., cumulative allocation of attention to the central vs. peripheral stimulus). Results The results showed that the initial saccade away from the centrally presented stimulus is followed by a rapid re-engagement of attention with the central stimulus, leading to cumulative preference for the central stimulus over the lateral stimulus over time. This pattern tended to be stronger for salient facial expressions as compared to non-face patterns, was replicable across two independent samples of 7-month-old infants, and differentiated between 7 and 5 month-old infants. Conclusion The results suggest that eye tracking based assessments of infants’ cumulative preference for faces over time can be readily parameterized and standardized, and may provide valuable techniques for future studies examining normative developmental changes in preference for social signals. Significance Standardized measures of early developing face preferences may have potential to become surrogate biomarkers of neurocognitive and social development. PMID:24845102

Upright face-preferential high-gamma responses in lower-order visual areas: evidence from intracranial recordings in children

PubMed Central

2015-01-01

Behavioral studies demonstrate that a face presented in the upright orientation attracts attention more rapidly than an inverted face. Saccades toward an upright face take place in 100-140 ms following presentation. The present study using electrocorticography determined whether upright face-preferential neural activation, as reflected by augmentation of high-gamma activity at 80-150 Hz, involved the lower-order visual cortex within the first 100 ms post-stimulus presentation. Sampled lower-order visual areas were verified by the induction of phosphenes upon electrical stimulation. These areas resided in the lateral-occipital, lingual, and cuneus gyri along the calcarine sulcus, roughly corresponding to V1 and V2. Measurement of high-gamma augmentation during central (circular) and peripheral (annular) checkerboard reversal pattern stimulation indicated that central-field stimuli were processed by the more polar surface whereas peripheral-field stimuli by the more anterior medial surface. Upright face stimuli, compared to inverted ones, elicited up to 23% larger augmentation of high-gamma activity in the lower-order visual regions at 40-90 ms. Upright face-preferential high-gamma augmentation was more highly correlated with high-gamma augmentation for central than peripheral stimuli. Our observations are consistent with the hypothesis that lower-order visual regions, especially those for the central field, are involved in visual cues for rapid detection of upright face stimuli.

Russell, Anthony P

2009-09-01

The current challenges (increasing levels of integration in the biological sciences) facing the teaching of zoology and the structure of the zoology curriculum are explored herein. General context is provided and a more focused scrutiny of the situation in North America is presented. The changing emphases in more broadly-based biological sciences programs in North America are outlined, and their influence on the role of zoology as part of fundamental biological training is considered. The longer term impact of such changes in emphasis on the teaching of zoology is discussed, and the central role that zoology can play in dealing with both science content and science education is advanced. Based upon a focal workshop on the future of the zoology curriculum in Canada, a perspective on the challenges facing curriculum evolution is provided. Extensive curriculum redesign is called for to ensure that zoology provides a broad-scale integrative approach to the understanding of biodiversity in evolutionary, ecological and functional contexts. Barriers to, and drivers of change are identified and the need for collaborative approaches to curricular evolution is emphasized. © 2009 ISZS, Blackwell Publishing and IOZ/CAS.

The role of eye movements in decision making and the prospect of exposure effects.

PubMed

Bird, Gary D; Lauwereyns, Johan; Crawford, Matthew T

2012-05-01

The aim of the current study was to follow on from previous findings that eye movements can have a causal influence on preference formation. Shimojo et al. (2003) previously found that faces that were presented for a longer duration in a two alternative forced choice task were more likely to be judged as more attractive. This effect only occurred when an eye movement was made towards the faces (with no effect when faces were centrally presented). The current study replicated Shimojo et al.'s (2003) design, whilst controlling for potential inter-stimuli interference in central presentations. As per previous findings, when eye movements were made towards the stimuli, faces that were presented for longer durations were preferred. However, faces that were centrally presented (thus not requiring an eye movement) were also preferred in the current study. The presence of an exposure duration effect for centrally presented faces casts doubt on the necessity of the eye movement in this decision making process and has implications for decision theories that place an emphasis on the role of eye movements in decision making.

Although a relatively recent epidemic, HIV is now increasing in Eastern Europe faster than anywhere else in the world. In the study reported in this paper, we interviewed 511 business people and health professionals in five Central and Eastern European nations: Estonia, Georgia, Hungary, Poland and Russia, deriving our questions primarily from a Social Representations perspective. Respondents also freely completed their associations with the stimulus word 'AIDS'. Our findings indicate that, although there is considerable agreement about the threat posed by the epidemic, there are also notable cultural differences in attributions about the origin and spread of the virus and the nature of those groups at risk of infection. These findings are interpreted in the light of the historical legacies of the Communist era, as well as the real economic and social challenges faced by the population of this region.

Why primary care practices should become digital health information hubs for their patients.

PubMed

Baird, Aaron; Nowak, Samantha

2014-11-25

Two interesting health care trends are currently occurring: 1) patient-facing technologies, such as personal health records, patient portals, and mobile health apps, are being adopted at rapid rates, and 2) primary care, which includes family practice, is being promoted as essential to reducing health care costs and improving health care outcomes. While these trends are notable and commendable, both remain subject to significant fragmentation and incentive misalignments, which has resulted in significant data coordination and value generation challenges. In particular, patient-facing technologies designed to increase care coordination, often fall prey to the very digital fragmentation issues they are supposed to overcome. Additionally, primary care providers are treating patients that may have considerable health information histories, but generating a single view of such multi-source data is nearly impossible. We contribute to this debate by proposing that primary care practices become digital health information hubs for their patients. Such hubs would offer health data coordination in a medically professional setting with the benefits of expert, trustworthy advice coupled with active patient engagement. We acknowledge challenges including: costs, information quality and provenance, willingness-to-share information and records, willingness-to-use (by both providers and patients), primary care scope creep, and determinations of technical and process effectiveness. Even with such potential challenges, we strongly believe that more debate is needed on this topic prior to full implementation of various health information technology incentives and reform programs currently being designed and enacted throughout the world. Ultimately, if we do not provide a meaningful way for the full spectrum of health information to be used by both providers and patients, especially early in the health care continuum, effectively improving health outcomes may remain elusive. We view the primary care practice as a central component of digital information coordination, especially when considering the current challenges of digital health information fragmentation. Given these fragmentation issues and the emphasis on primary care as central to improving health and lower overall health care costs, we suggest that primary care practices should embrace their evolving role and should seek to become digital health information hubs for their patients.

Challenges faced by caregivers of children on antiretroviral therapy at Mutale Municipality selected healthcare facilities, Vhembe District, Limpopo Province.

Children depend solely on caregivers who can be either parents or guardians for drug administration to enhance adherence to antiretroviral treatment (ART), which might pose any number of challenges. The purpose of this study was to explore and describe the challenges faced by caregivers of children on ART at Mutale Municipality, Vhembe District, Limpopo Province. The research design was qualitative, explorative, descriptive and contextual in nature. The population consisted of 16 caregivers who were 18 years of age and above, and mentally capable, irrespective of educational qualifications, caring for children aged between 0 and 15 years who were on ART between April 2013 and October 2014. Non-probability, purposive sampling was used to select the 16 caregivers. Required permission, approval and ethical clearance were obtained from the University of Venda Higher Degree Committee, Limpopo Provincial Health Department and relevant institutions. An in-depth, individual, unstructured interview method was used to collect data. One central question was asked: 'What are the challenges you experience when caring for a child on antiretroviral treatment?' Subsequent questions were based on the participants' responses to the central question. Qualitative data were analysed by means of Tesch's open-coding method. The findings of this study revealed that participants, that is, caregivers of children on ART, experienced financial burdens because of transport costs needed to comply with follow-up dates and insufficient of money for food, clothing the child in need of care, pocket money for lunch boxes during school hours and time lost while waiting for consultations. Participants reported some level of stigmatisation against children on ART by family members, especially the husbands or in-laws of the secondary caregivers. Many primary and secondary caregivers seemed to have given up seeking support from government and community structures. The conclusions drawn from this research are that caregivers hardly receive any support from family members or the community. Fear of disclosing the HIV-positive status of children resulted in the delay of financial support from the government, thus leading to serious financial burden on the caregivers.

Local visual perception bias in children with high-functioning autism spectrum disorders; do we have the whole picture?

While local bias in visual processing in children with autism spectrum disorders (ASD) has been reported to result in difficulties in recognizing faces and facially expressed emotions, but superior ability in disembedding figures, associations between these abilities within a group of children with and without ASD have not been explored. Possible associations in performance on the Visual Perception Skills Figure-Ground test, a face recognition test and an emotion recognition test were investigated within 25 8-12-years-old children with high-functioning autism/Asperger syndrome, and in comparison to 33 typically developing children. Analyses indicated a weak positive correlation between accuracy in Figure-Ground recognition and emotion recognition. No other correlation estimates were significant. These findings challenge both the enhanced perceptual function hypothesis and the weak central coherence hypothesis, and accentuate the importance of further scrutinizing the existance and nature of local visual bias in ASD.

Health Professionals Facing Burnout: What Do We Know about Nursing Managers?

Objective. To address the degree of burnout in nursing managers in hospitals of Western Switzerland, including comparison with medical managers, and its relationship with personal, work-related, and organizational characteristics. Methods. Statistical analysis of the scores of the Maslach Burnout Inventory-Human Services Survey from 257 nursing managers who answered a standardized electronic questionnaire. Results. Nursing managers showed a low degree of burnout, which was similar to that of medical managers. Most of them had a low level of emotional exhaustion and a low level of depersonalization, while personal accomplishment was contrasted. Only 2.3% had a high degree of burnout. These findings challenge the hypothesis of high stress being associated with high burnout, as nursing managers can be supposed to have a highly demanding job due to their intermediary position within the hospital hierarchy. Variations of burnout by personal, work-related, and organizational characteristics mainly concerned emotional exhaustion. Conclusion. Though nursing managers face a highly demanding job, they may benefit from resources (including coping strategies and empowerment) which help counterbalance job stress. Unequal distribution of resources may play a central role when facing burnout.

The face plays a central role in interpersonal communication and aesthetic perception. Moreover, due to the heavy dependence of ocular function on lid anatomy, the treatment of periocular injuries, particularly those involving soft tissue loss, requires profound knowledge of both anatomy and reconstructive plastic surgery. Numerous surgical procedures are described in the literature. The aim of these procedures is to achieve an optimal functional and aesthetic result according to injury localization and extent. Against this background, treating eyelid injuries presents certain challenges. Close collaboration between all areas of head surgery is required particularly in the case of large defects.

Merging software from 36 independent work packages into a coherent, unified software system with a lifespan of twenty years is the challenge faced by the Magdalena Ridge Observatory Interferometer (MROI). We solve this problem by using standardized interface software automatically generated from simple highlevel descriptions of these systems, relying only on Linux, GNU, and POSIX without complex software such as CORBA. This approach, based on gigabit Ethernet with a TCP/IP protocol, provides the flexibility to integrate and manage diverse, independent systems using a centralized supervisory system that provides a database manager, data collectors, fault handling, and an operator interface.

Psychocentricity and participant profiles: implications for lexical processing among multilinguals

Libben, Gary; Curtiss, Kaitlin; Weber, Silke

2014-01-01

Lexical processing among bilinguals is often affected by complex patterns of individual experience. In this paper we discuss the psychocentric perspective on language representation and processing, which highlights the centrality of individual experience in psycholinguistic experimentation. We discuss applications to the investigation of lexical processing among multilinguals and explore the advantages of using high-density experiments with multilinguals. High density experiments are designed to co-index measures of lexical perception and production, as well as participant profiles. We discuss the challenges associated with the characterization of participant profiles and present a new data visualization technique, that we term Facial Profiles. This technique is based on Chernoff faces developed over 40 years ago. The Facial Profile technique seeks to overcome some of the challenges associated with the use of Chernoff faces, while maintaining the core insight that recoding multivariate data as facial features can engage the human face recognition system and thus enhance our ability to detect and interpret patterns within multivariate datasets. We demonstrate that Facial Profiles can code participant characteristics in lexical processing studies by recoding variables such as reading ability, speaking ability, and listening ability into iconically-related relative sizes of eye, mouth, and ear, respectively. The balance of ability in bilinguals can be captured by creating composite facial profiles or Janus Facial Profiles. We demonstrate the use of Facial Profiles and Janus Facial Profiles in the characterization of participant effects in the study of lexical perception and production. PMID:25071614

Central Role of the Trehalose Biosynthesis Pathway in the Pathogenesis of Human Fungal Infections: Opportunities and Challenges for Therapeutic Development

PubMed Central

Thammahong, Arsa; Puttikamonkul, Srisombat; Perfect, John R.; Brennan, Richard G.

2017-01-01

SUMMARY Invasive fungal infections cause significant morbidity and mortality in part due to a limited antifungal drug arsenal. One therapeutic challenge faced by clinicians is the significant host toxicity associated with antifungal drugs. Another challenge is the fungistatic mechanism of action of some drugs. Consequently, the identification of fungus-specific drug targets essential for fitness in vivo remains a significant goal of medical mycology research. The trehalose biosynthetic pathway is found in a wide variety of organisms, including human-pathogenic fungi, but not in humans. Genes encoding proteins involved in trehalose biosynthesis are mechanistically linked to the metabolism, cell wall homeostasis, stress responses, and virulence of Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus. While there are a number of pathways for trehalose production across the tree of life, the TPS/TPP (trehalose-6-phosphate synthase/trehalose-6-phosphate phosphatase) pathway is the canonical pathway found in human-pathogenic fungi. Importantly, data suggest that proteins involved in trehalose biosynthesis play other critical roles in fungal metabolism and in vivo fitness that remain to be fully elucidated. By further defining the biology and functions of trehalose and its biosynthetic pathway components in pathogenic fungi, an opportunity exists to leverage this pathway as a potent antifungal drug target. The goal of this review is to cover the known roles of this important molecule and its associated biosynthesis-encoding genes in the human-pathogenic fungi studied to date and to employ these data to critically assess the opportunities and challenges facing development of this pathway as a therapeutic target.

Expanded Transposition Flap Technique for Total and Subtotal Resurfacing of the Face and Neck

PubMed Central

Spence, Robert J.

2007-01-01

Background: The reconstruction of major burn and other deformities resulting from significant soft tissue deficits of the face and neck is a continuing challenge for surgeons who wish to reliably restore facial function and aesthetic appearance. A primary problem is deficiency of well-matched donor skin. Other problems include the unique characteristics of facial skin, the fine anatomic nuances, and the unique functional demands placed on the face. This article describes an expanded shoulder transposition flap that can provide a large amount of both flap and full-thickness skin graft for total and subtotal reconstruction of the face. Methods: An expanded shoulder transposition flap has been used since 1986 for head and neck resurfacing 58 times in 41 patients ranging in age from 2 to 62 years. The details of the technique and the results of the flap including complications are described. Results: The flap proved remarkably reliable and reproducible in resurfacing the peripheral facial aesthetic units. The pedicle skin is often used for grafting of the central face with its finer features. The donor site of the flap is closed primarily. Conclusions: Twenty years' experience with expanded transposition flaps has shown it to be reliable and versatile in the reconstruction of major soft tissue deficits of the face and neck. It is a technique that provides economy of tissue, versatility, and is well within the skill, patience, and courage of most reconstructive surgeons. PMID:17534420

The Lockheed Blackbirds hold a unique place in the development of aeronautics. In their day, the A-12, YF-12, M-21, D-21, and SR-71 variants outperformed all other jet airplanes in terms of altitude and speed. Now retired, they remain the only production aircraft capable of sustained Mach 3 cruise and operational altitudes above 80,000 feet. In this paper the author describes the design evolution of the Blackbird from Lockheed's early Archangel studies for the Central Intelligence Agency through Senior Crown, production of the Air Force's SR-71. He describes the construction and materials challenges faced by Lockheed, the Blackbird's performance characteristics and capabilities, and the National Aeronautics and Space Administration's role in using the aircraft as a flying laboratory to collect data on materials, structures, loads, heating, aerodynamics, and performance for high-speed aircraft.

Fluid flow enhances the effectiveness of toxin export by aquatic microorganisms: a first-passage perspective

NASA Astrophysics Data System (ADS)

Licata, Nicholas; Clark, Aaron

2014-03-01

Aquatic microorganisms face a variety of challenges in the course of development. One central challenge is efficiently regulating the export of toxic molecules inside the developing embryo. The strategies employed should be robust with respect to the variable ocean environment and limit the chances that exported toxins are reabsorbed. In this talk we consider the first-passage problem for the uptake of exported toxins by a spherical embryo. A perturbative solution of the advection-diffusion equation reveals that a concentration boundary layer forms in the vicinity of the embryo, and that fluid flow enhances the effectiveness of toxin export. We highlight connections between the model results and recent experiments on the development of sea urchin embryos.

Changing societies and four tasks of schooling: Challenges for strongly differentiated educational systems

NASA Astrophysics Data System (ADS)

2014-05-01

Changing labour markets, increased calls for selection and excellence, and increased diversity and individualisation have repercussions on how educational systems can prepare youth for work, optimise knowledge production, achieve equality of opportunity, and socialise students into active civic engagement. This paper discusses four central tasks of schooling and examines to what extent societal developments challenge education policy to deliver on the tasks at hand. Particular attention is given to the challenges Europe's strongly diversified educational systems are currently facing. Both the Netherlands and Germany, for example, have been offering vocationally-oriented pathways alongside traditional academic higher education for some time. But today's ongoing changes in job descriptions, mainly due to ever-accelerating technological developments, are causing a risk of skills obsolescence which can only be avoided by continuous upskilling and/or reskilling of a sufficiently flexible workforce. Overcoming differences of intelligence as well as differences of diverse socioeconomic, ethnic and linguistic backgrounds by way of education is another challenge, as is fostering "soft" skills and political awareness. This paper investigates the effectiveness of current education systems in preparing citizens for a functioning modern society.

The Challenges of Participant Photography: A Critical Reflection on Methodology and Ethics in Two Cultural Contexts.

PubMed

Murray, Linda; Nash, Meredith

2017-05-01

Photovoice and photo-elicitation are two common methods of participant photography used in health research. Although participatory photography has many benefits, this critical reflection provides fellow researchers with insights into the methodological and ethical challenges faced when using such methods. In this article, we critically reflect on two studies that used participatory photography in different cultural contexts. The first study used photo-elicitation to investigate mothers' experiences of infant settling in central Vietnam. The second study used photovoice to explore pregnant embodiment in Australia. Following a discussion of the literature and a detailed overview of the two studies, we examine the methodological challenges in using participant photography before, during and after each study. This is followed by a discussion of ethical concerns that arose in relation to the burden of participation, confidentiality, consent, and the photographing of families and children. To conclude, we highlight implications for using participatory photography in other settings.

We conducted a cross-sectional study involving completion of self-report measures. Individuals who acquire a spinal cord injury (SCI) face numerous physical and psychological challenges, with the former receiving considerable less attention during the rehabilitation process. In this article, we examined event centrality as a unique predictor of psychological outcomes in a sample of individuals receiving rehabilitation for SCI. Event centrality refers to the extent to which individuals construe a stressful experience as a core part of their identity. In samples of individuals exposed to psychological traumas (for example, sexual assault or military combat), event centrality has emerged as a consistent and powerful predictor of posttraumatic stress symptoms (PTSSs). This is the first study to examine event centrality in an SCI sample. Inpatient rehabilitation program in a large urban city in the Southwestern United States. A sample of 55 participants in rehabilitation for a recent SCI completed measures of event centrality, PTSS, depressed mood and perceived disability. Event centrality was significantly related to perceived disability (r=0.48) and PTSS (r=0.31) and accounted for unique variance in these two outcomes after controlling for demographics and depressed mood. Event centrality is common among individuals with SCI and may be a unique contributor to worse psychological and functional outcomes. We hope our findings will alert health-care professionals to the importance of event centrality. This study was supported by a grant from the Danish National Research Foundation (DNRF89).

Examining the structural challenges to communication as experienced by nurse managers in two US hospital settings.

PubMed

Marx, Marcia

2014-11-01

This study examined the structural barriers to communication for first-line nurse managers with their staff nurses. The delivery of quality care depends on effective communication in hospital units. First-line nurse managers are central figures in networks whose responsibility is to communicate information from the senior management to staff nurses. The data were collected using face-to-face interviews with first-line managers at two US hospitals The interviews were transcribed and coded with limited use of the qualitative software atlas Interview questions focused on work experiences of managers with special emphases on communication. Structural barriers that influenced managers' communication included the amount of face-to-face interaction with nurses, the amount of information to communicate, levels of formalization, outreach to all nurses, time constraints and nurses' subcultural networks These factors compromised managers' ability to communicate effectively with nurses. Managers should carefully examine how structure affects communication recognizing that some dynamics of structure cannot be changed but that they can influence others, such as formalization and communication networks. Managers should examine their own positioning within nurses' networks and demonstrate to nurses that their expertise contributes to the collaborative capital upon which nursing practice depends. © 2013 John Wiley & Sons Ltd.

Acquisition of the spatial temperature distribution of rock faces by using infrared thermography

NASA Astrophysics Data System (ADS)

Beham, Michael; Rode, Matthias; Schnepfleitner, Harald; Sass, Oliver

2013-04-01

Rock temperature plays a central role for weathering and therefore influences the risk potential originating from rockfall processes. So far, for the acquisition of temperature mainly point-based measuring methods have been used and accordingly, two-dimensional temperature data is rare. To overcome this limitation, an infrared camera was used to collect and analyse data on the spatial temperature distribution on 10 x 10 m sections of rock faces in the Gesäuse (900m a.s.l.) and in the Dachsteingebirge (2700m a.s.l.) within the framework of the research project ROCKING ALPS (FWF-P24244). The advantage of infrared thermography to capture area-wide temperatures has hardly ever been used in this context. In order to investigate the differences between north-facing and south-facing rock faces at about the same period of time it was necessary to move the camera between the sites. The resulting offset of the time lapse infrared images made it necessary to develop a sophisticated methodology to rectify the captured images in order to create matching datasets for future analysis. With the relatively simple camera used, one of the main challenges was to find a way to convert the colour-scale or grey-scale values of the rectified image back to temperature values after the rectification process. The processing steps were mainly carried out with MATLAB. South-facing rock faces generally experienced higher temperatures and amplitudes compared to the north facing ones. In view of the spatial temperature distribution, the temperatures of shady areas were clearly below those of sunny ones, with the latter also showing the highest amplitudes. Joints and sun-shaded areas were characterised by attenuated diurnal temperature fluctuations closely paralleled to the air temperature. The temperature of protruding rock parts and of loose debris responded very quick to changes in radiation and air temperatures while massive rock reacted more slowly. The potential effects of temperature on weathering could only be assessed in a qualitative way by now. However, the variability of temperatures and amplitudes on a rather small and homogeneous section of a rockwall is surprisingly high which challenges any statements on weathering effectiveness based on point measurements. In simple terms, the use of infrared thermography has proven its value in the presented pilot study and is going to be a promising tool for research into rock weathering.

This paper provides the first report of the invasive Asian fish tapeworm, Bothriocephalus acheilognathi Yamaguti, 1934, in Honduras. The cestode was found in Profundulus portillorum (Cyprinodontiformes: Profundulidae), which represents a new host record, and which is a member of a genus faced with a variety of conservation challenges, now potentially complicated by the presence of this pathogenic cestode. Nearly complete sequence data from the ITS-1 5.8S and ITS-2 regions corroborate the determination based on morphological characteristics. Several species of carp were introduced to Honduras for aquaculture purposes in the early 1980s and the presence of the Asian fish tapeworm in Honduras may be related to these introductions. In addition, this report documents the currently known geographical distribution of this parasite in Central America, first recorded from Panamá and now from Honduras. PMID:25654444

Theobald, Sally; Tolhurst, Rachel; Elsey, Helen; Standing, Hilary; Standing, Helen

2005-05-01

The increasing ascendancy of 'gender mainstreaming' as the central approach to improving gender equity has largely determined strategies to integrate a gender focus in sector-wide approaches (SWAps). This paper explores the impetus for and process of gender mainstreaming in SWAps in the Ministries of Health in Uganda, Ghana, Malawi and Mozambique, and outlines some achievements and challenges. The shifting and contested relationships between the Ministry of Health, donors and other government ministries (such as Ministries of Finance and Ministries of Women's Affairs/Gender) are important in shaping the opportunities and constraints faced in gender mainstreaming. The refocusing of resource allocation to different sectors has led to changes in the balance of power between the various actors at the national level, with diverse implications for promoting gender equity in health. Some of the achievements to date and ongoing challenges are explored through concrete examples from different countries. These include: the development of structures for mainstreaming, including the dilemmas of the 'focal points' approach and the role of national gender mainstreaming machinery; the need for training and building capacity to identify and address gender issues, which involves engaging with new languages and concepts, and developing new skills; building alliances, consensus and momentum; integrating gender concerns into policy and planning documents; and promoting gender equity in human resources in the health sector. Cross-cutting themes underlying these challenges are the need for gender-specific information and ways to finance mainstreaming strategies. Implications are drawn for ways forward, without losing sight of the challenge of translating discourses of gender mainstreaming, and its central ideal of social transformation, into pragmatic strategies in the bureaucratic environment.

The upsurge in the uptake of antiretroviral therapy (ART) has led to a significant increase in the survival of vertically acquired HIV infected children, many of whom are currently living into adolescence and early adulthood. However little if anything is known of the lived experiences and the challenges faced by HIV positive adolescents in the African context. We set out to investigate psychosocial challenges faced by HIV infected adolescents on the Kenyan coast. A total of 44 participants (12 HIV-infected adolescents, 7 HIV uninfected adolescents, and 25 key informants) took part in this qualitative study, using individually administered in-depth interviews. A framework approach was used to analyze the data using NVIVO software. We observed that the challenges faced by adolescents in rural Kenya could be placed into six major themes: poverty, poor mental and physical health, the lack of a school system that is responsive to their needs, challenges in how to disclose to peers and family members, high levels of stigma in its various forms, and challenges of medical adherence leading to the need for close monitoring. In this African community, vertically acquired HIV-infected adolescents face a complex set of social, economic and medical challenges. Our study points to the urgent need to develop multisectorial intervention support programmes to fully address these challenges.

to explore midwifery leaders' narratives of identity, within the context of one region of England. a qualitative study using narrative identity theory. Data were collected using in-depth, loosely structured narrative interviews. the study was undertaken in the Midlands region of England, in the context of a midwifery-specific leadership development programme. Participants were located in local NHS organisations and higher education institutions. the interviewees were midwives currently in one of a variety of formal leadership roles, who had recently completed a midwifery leadership development programme. Nine leaders were interviewed for the study. two central themes emerged: 'I am still a midwife' showed interviewees' continued self-identification according to their professional identity, despite the majority no longer holding a clinical role; 'Between a rock and a hard place' showed the challenges of maintaining a professionally-based identity narrative in the face of group and organisational discourses. among the midwifery leaders interviewed, narratives centred on a continued midwife self-identification. However, participants faced a number of challenges in maintaining this narrative, within the context of wider professional group and organisational discourses. midwifery leaders require the support of their professional group and organisational structures if they are to maintain a positive self- and social-identity.

McKenzie, Shanice A; Rasmussen, Kathleen M; Garner, Christine D

2018-01-01

Women face societal and cultural barriers to breastfeeding. These challenges have been investigated in international studies and U.S. public opinion polls; however, mothers' experiences with breastfeeding in public in the United States remain unexplored. Research aim: The aim of this study was to describe the experiences of obese and normal-weight women with breastfeeding in public in central New York. Pregnant women ( N = 26) in central New York who intended to breastfeed and were either normal weight or obese were enrolled during their third trimester. A longitudinal, qualitative study was conducted to obtain information about women's experiences from birth through 3 to 6 months postpartum. Interviews were audio recorded, transcribed, and verified for accuracy. Transcripts were analyzed iteratively using conventional content analysis. The concept of "public" was situational rather than a set of physical places; women experienced challenges while breastfeeding around others in private locations that were indistinguishable from those they encountered in places typically considered public. Women experienced social and physical awkwardness including perceived lack of acceptability, fear of confrontation, exposure, and positioning difficulties. They used strategies to reduce awkwardness, for example, being "discreet" and minimizing breastfeeding around other people. Obese women experienced similar challenges but to a greater degree than normal-weight women. "Breastfeeding around others" described mother's experiences more accurately than "breastfeeding in public" and was experienced as awkward both socially and physically, particularly by obese women. Strategies are needed to normalize breastfeeding in the United States and to prepare mothers for the challenges of breastfeeding around others.

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.

Growth of the Asian health-care market: global implications for the pharmaceutical industry.

2007-10-01

The global economy is being transformed by an explosion of information unleashed by the internet, the digital revolution, communications and increased international mobility. This transformation is manifesting in many ways, including rapid development of countries such as China, commoditization of public services, mobilization of workforces, shifting of market control from suppliers to consumers, interlinked rises in product demand and customer expectations, and problems regulating international business competition. As Asia is home to half of the world's population, and offers both a large relatively low-cost workforce in some countries and a potentially huge retail market, this region could be central to the future of the global economy. Like other industries, the pharmaceutical industry faces a new array of Asia-specific opportunities and challenges. Success in meeting these challenges will go to those pharmaceutical companies that best understand the unique strengths and constraints of Asia's diverse cultures, talents and markets.

Conceptual Challenges of the Systemic Approach in Understanding Cell Differentiation.

PubMed

Paldi, Andras

2018-01-01

The cells of a multicellular organism are derived from a single zygote and genetically identical. Yet, they are phenotypically very different. This difference is the result of a process commonly called cell differentiation. How the phenotypic diversity emerges during ontogenesis or regeneration is a central and intensely studied but still unresolved issue in biology. Cell biology is facing conceptual challenges that are frequently confused with methodological difficulties. How to define a cell type? What stability or change means in the context of cell differentiation and how to deal with the ubiquitous molecular variations seen in the living cells? What are the driving forces of the change? We propose to reframe the problem of cell differentiation in a systemic way by incorporating different theoretical approaches. The new conceptual framework is able to capture the insights made at different levels of cellular organization and considered previously as contradictory. It also provides a formal strategy for further experimental studies.

ABSTRACT The “invisible army” of clinical microbiologists is facing major changes and challenges. The rate of change in both the science and technology is accelerating with no end in sight, putting pressure on our army to learn and adapt as never before. Health care funding in the United States is undergoing dramatic change which will require a new set of assumptions about how clinical microbiology is practiced here. A major challenge facing the discipline is the replacement of a generation of clinical microbiologists. In my opinion, it is incumbent on us in the invisible army to continue to work with the American Society for Microbiology (ASM) in meeting the future challenges faced by our discipline. In this commentary, I will first discuss some recent history of clinical microbiology within ASM and then some current challenges we face. PMID:28659316

Challenges in the management of community pharmacies in Malaysia

PubMed Central

2017-01-01

Background: The provision of professional pharmacy services by community pharmacists continues to be limited, particularly in low and middle income countries. It was postulated that multiple management challenges faced by community pharmacists contribute to this situation. Objective: The primary aim of the research was to determine the challenges faced in the management of community pharmacies in Sarawak (the largest state in Malaysia), and practical strategies to cope and overcome the challenges. Methods: Semi-structured interviews were carried out with community pharmacists practising in Sarawak. Purposive and snowball sampling were employed to ensure a diverse group of informants. The interviews were audio-recorded and transcribed verbatim, with the resultant data analysed using thematic analysis. Data collection, coding, interpretation were carried out iteratively until theoretical saturation. Results: Twenty respondents from different demographic characteristics were recruited. Six major themes were identified. Management challenges faced by community pharmacists traverse five major domains: market competition, legislative issues, customers’ knowledge and expectations, macroeconomic impacts and operational challenges. Most of these challenges require government intervention to be resolved. In the meantime, improving customer service and expanding the range of professional services were seen as the most viable strategies to cope with existing challenges. The main concern is that current legislative and economic landscape may hinder these strategies. Enactment of dispensing separation and more protective measures against market competition were suggested to alleviate the challenges faced. Conclusion: Numerous management challenges faced by community pharmacists that distract them from delivering professional pharmacy services have been highlighted. Urgent affirmative actions by the government are warranted in supporting community pharmacists to realise and maximise their potentials. PMID:28690697

Central Role of the Trehalose Biosynthesis Pathway in the Pathogenesis of Human Fungal Infections: Opportunities and Challenges for Therapeutic Development.

Invasive fungal infections cause significant morbidity and mortality in part due to a limited antifungal drug arsenal. One therapeutic challenge faced by clinicians is the significant host toxicity associated with antifungal drugs. Another challenge is the fungistatic mechanism of action of some drugs. Consequently, the identification of fungus-specific drug targets essential for fitness in vivo remains a significant goal of medical mycology research. The trehalose biosynthetic pathway is found in a wide variety of organisms, including human-pathogenic fungi, but not in humans. Genes encoding proteins involved in trehalose biosynthesis are mechanistically linked to the metabolism, cell wall homeostasis, stress responses, and virulence of Candida albicans , Cryptococcus neoformans , and Aspergillus fumigatus . While there are a number of pathways for trehalose production across the tree of life, the TPS/TPP (trehalose-6-phosphate synthase/trehalose-6-phosphate phosphatase) pathway is the canonical pathway found in human-pathogenic fungi. Importantly, data suggest that proteins involved in trehalose biosynthesis play other critical roles in fungal metabolism and in vivo fitness that remain to be fully elucidated. By further defining the biology and functions of trehalose and its biosynthetic pathway components in pathogenic fungi, an opportunity exists to leverage this pathway as a potent antifungal drug target. The goal of this review is to cover the known roles of this important molecule and its associated biosynthesis-encoding genes in the human-pathogenic fungi studied to date and to employ these data to critically assess the opportunities and challenges facing development of this pathway as a therapeutic target.

Towards Global Transdisciplinary Research: Lessons Learned from the Belmont Forum

2014-12-01

The Belmont Forum was initiated in 2009 by a sub group of the International Group of Funding Agencies for Global Change Research. The Belmont Challenge embodies the Forum's central goal: to deliver knowledge needed for societies to take action to mitigate and adapt to detrimental environmental change. This is fostered through collaboration among scientists across the globe and by stressing the importance of co-production of knowledge associated with coupled natural and social systems. The Belmont Challenge was clearly aligned with other collective thinking processes within the research community and key knowledge users from intergovernmental bodies. Convergence of these efforts gave rise to the S&T Alliance for Global Sustainability and its initiative - Future Earth. Collaborative Research Actions, consisting primarily of multilateral research calls to address topics relevant to Future Earth, have been the main tool developed to address the Belmont Challenge and some early lessons emerged. First, obstacles faced by the Belmont Forum are similar to those met by scientists collaborating across traditional boundaries. Building shared languages and interests between various disciplines and across global cultures, remains difficult; this results in a persistent underestimation of the transformation required to move knowledge creation towards a truly global inter- and transdisciplinary science. Second, the diversity of organizations, cultures and practices within the Belmont Forum is the main source of its creativity and its challenges. While some convergence is needed to build coherent strategies and work efficiently together, diversity is necessary to design actions suitable for all partners regardless of their national research system and science-policy priorities. Finding the right trade-offs is a learning process that Future Earth is also facing; thus both initiatives are not only linked through funding relations but also through strongly intertwined learning curves.

The aim of the present study was to evaluate the lay perception of the effect of the buccal corridor and amount of tooth-gingival display on the attractiveness of a smile in different facial types. Using Adobe Photoshop CS3 software, frontal facial images of two smiling Iranian female subjects (one short-faced and one long-faced) were altered to create different magnitudes of buccal corridor display (5, 10, 15, 20 and 25%) and tooth-gingival display (2 mm central incisor show, 6 mm central incisor show, total central incisor show, total tooth show with 2 mm gingival show and total tooth show with 4 mm gingival show). Sixty Iranians (30 males and 30 females) rated the attractiveness of the pictures on a 1-5 point scale. Narrower smiles were preferred in long-faced subjects compared with short-faced subjects. Minimal tooth show was more attractive than excessive gingival display in short-faced subjects. There were no gender specific, statistically significant differences found in the ratings given by the lay assessors. Harmonious geometry of the smile and face in both the vertical and transverse dimensions influences smile attractiveness and this should be considered in orthodontic treatment planning.

Patients with head and neck cancer face a number of challenges in terms of treatment, cure of their underlying malignant condition, and quality of survivorship. This presentation will focus on the patient perception of both the quality of care and the empathy and availability of the head and neck oncology team. It has become evident that the quality of survivorship plays a central role in the patient's decision-making process. The process of decision making by the patient facing head and neck cancer and the impact on treatment choices will be explored. The ability of the patient and her or his support system to navigate through the increasingly complicated health care system will be considered, with an emphasis on strategies for success. Finally, the role of the of the head and neck surgeon, and the need for physician wellness in predicating successful patient outcomes will be considered. The ultimate goal of achieving optimal care, superior patient outcomes, and patient satisfaction is the true objective of the concept of living in a patient-centric universe.

Obtaining Reimbursement in France and Italy for New Diabetes Products

Schaefer, Elmar; Sonsalla, Jessica

2015-01-01

Manufacturers launching next-generation or innovative medical devices in Europe face a very heterogeneous reimbursement landscape, with each country having its own pathways, timing, requirements and success factors. We selected 2 markets for a deeper look into the reimbursement landscape: France, representing a country with central decision making with defined processes, and Italy, which delegates reimbursement decisions to the regional level, resulting in a less transparent approach to reimbursement. Based on our experience in working on various new product launches and analyzing recent reimbursement decisions, we found that payers in both countries do not reward improved next-generation products with incremental reimbursement. Looking at innovations, we observe that manufacturers face a challenging and lengthy process to obtain reimbursement. In addition, requirements and key success factors differ by country: In France, comparative clinical evidence and budget impact very much drive reimbursement decisions in terms of pricing and restrictions, whereas in Italy, regional key opinion leader (KOL) support and additional local observational data are key.

2017-05-31

Early diagnosis and treatment of breast cancer results in an increasing number of survivors, some of whom face new challenges in their transition to daily life. Based on these experiences, the aim of this study was to describe the everyday life in breast cancer survivors experiencing challenges. Eleven women recruited from a follow-up study of breast cancer patients participated in qualitative interviews about their everyday occupations seven years after ending treatment. The inductive analysis revealed ten categories that were organized into five subthemes under the two main themes 'bodily and mental loneliness' and 'new center of gravity in everyday life'. Findings showed how relevant information and guidance; active support to the client and their relatives; and a balance between occupations at home and at work were important matters to handle their everyday life challenges. By assisting these women in finding new patterns of meaningful occupations that positively affect their everyday life, the study suggests some central elements to be included in future follow-up practice for breast cancer survivors. Approaching this goal, occupational therapists should contribute to more involvement assisting cancer survivors and their partners in finding new patterns of meaningful occupations that positively affect their everyday life.

Horton-Deutsch, Sara; Young, Patricia K; Nelson, Kristine A

2010-05-01

The aim of the present study was to explore the experience of becoming a nurse faculty leader. In a recent interpretation of 23 interviews conducted with nurse faculty leaders from across the United States about their experiences of becoming a leader three themes were identified: being thrust into leadership, taking risks and facing challenges. This interpretive phenomenological study further explicates three aspects of how nurse educators faced challenges in becoming and serving as a leader. Facing challenges meant reflecting, persevering through difficulties and learning to relate to others in new ways. Exemplars of participant experiences are provided for concreteness, to assist readers in determining how findings resonate with their own experience and how they can actualize this resonance in their own leadership practice. In the present study, reflecting, persevering through difficulties and learning to relate with others in a new way was how leaders faced challenges. Leadership development opportunities that facilitate self-exploration, caring and thoughtful interactions with others and values clarification serve as the foundation for becoming a nurse faculty leader who is, in turn, able to build leadership capacity in other individuals and organizations.

Local, regional and national interoperability in hospital-level systems architecture.

PubMed

Mykkänen, J; Korpela, M; Ripatti, S; Rannanheimo, J; Sorri, J

2007-01-01

Interoperability of applications in health care is faced with various needs by patients, health professionals, organizations and policy makers. A combination of existing and new applications is a necessity. Hospitals are in a position to drive many integration solutions, but need approaches which combine local, regional and national requirements and initiatives with open standards to support flexible processes and applications on a local hospital level. We discuss systems architecture of hospitals in relation to various processes and applications, and highlight current challenges and prospects using a service-oriented architecture approach. We also illustrate these aspects with examples from Finnish hospitals. A set of main services and elements of service-oriented architectures for health care facilities are identified, with medium-term focus which acknowledges existing systems as a core part of service-oriented solutions. The services and elements are grouped according to functional and interoperability cohesion. A transition towards service-oriented architecture in health care must acknowledge existing health information systems and promote the specification of central processes and software services locally and across organizations. Software industry best practices such as SOA must be combined with health care knowledge to respond to central challenges such as continuous change in health care. A service-oriented approach cannot entirely rely on common standards and frameworks but it must be locally adapted and complemented.

2009-01-01

To evaluate the supply cycle of antiretroviral (ARV) drugs, overseen by the National Program to Combat Human Retroviruses, AIDS, and STDs, through its order fulfillment indicators, and to obtain input from supply chain stakeholders. A study was carried out from April-September 2005 in the pharmacies of two hospitals in Rosario, Argentina, involving both a quantitative analysis of indicators and secondary sources and a qualitative evaluation using semistructured interviews. The indicators reveal the impact that interruptions in ARV supply stream from the Program (central level) have and the overstocking that takes place at the pharmacies (local level) to manage the shortages. Changes in ARV treatment account for over 50% of the prescriptions. Fulfillments fall short of the reference value. The interviewees shared possible strategies for overcoming the communication gaps between levels, for building-up stock, for guaranteeing availability, and for shortening waiting times; reached informal agreements to deal with the lack of policies and the shortage of staff; acknowledged the challenges facing the jurisdictions (central, intermediate, and local/community); and recognized local efforts to improve management. These challenges could be the starting point for building teams to work on effectively decentralizing the entire supply chain and allowing the Program to fulfill its much-needed oversight role.

2017-11-22

To report a case of central retinal vein occlusion resulting in a perivenular pattern of paracentral acute middle maculopathy lesions best identified with en face optical coherence tomography (OCT). Retrospective case report. Optos ultra-widefield fluorescein angiography, spectral domain OCT, en face OCT, and OCT angiography were performed. A 41-year-old man presented with decreased vision in the right eye for 2 weeks. Funduscopic examination of the affected right eye was notable for subtle retinal whitening in the macula, mild retinal venous dilation and tortuosity, and few scattered retinal dot and blot hemorrhages consistent with an acute central retinal vein occlusion. Widefield fluorescein angiography demonstrated delayed arterial and venous filling but no evidence of significant peripheral retinal vascular ischemia. En face OCT segmented at the inner nuclear layer illustrated a remarkable and precise perivenular distribution of fern-like paracentral acute middle maculopathy with periarterial sparing, whereas en face OCT segmented at the outer nuclear layer demonstrated florid cystoid macular edema. At 6-week follow-up, OCT demonstrated patchy areas of atrophic inner nuclear layer and spontaneous resolution of the cystoid macular edema. Optical coherence tomography angiography at the level of the deep capillary plexus illustrated remarkable flow reduction of the deep capillary plexus in mainly a perivenular distribution. The authors report a case of a central retinal vein occlusion with mild retinal findings associated with a remarkable perivenular pattern of paracentral acute middle maculopathy with en face OCT. Follow-up OCT angiography demonstrated significant flow reduction of the deep capillary plexus in a perivenular pattern. The perivenular pattern of paracentral acute middle maculopathy lesions with en face OCT can be an important finding suggestive of a central retinal vein occlusion.

To explore the challenges facing pharmacovigilance in Saudi Arabia and formulate recommendations to improve it from the perspective of healthcare professionals in Saudi Arabia. This was a qualitative study of 4 focus group discussions with pharmacists, physicians, and academicians held under the auspices of the King Saud University School of Pharmacy and the Center for Medicine in the Public Interest, Riyadh, Saudi Arabia. A total of 29 eligible healthcare professionals were invited to participate in the discussion. The predefined themes of the study were the current practice and major challenges facing pharmacovigilance in regulatory bodies, hospitals, the community, and academia, as well as recommendations to improve pharmacovigilance practice.  Of the 29 participants invited, 27 attended the discussion. Challenges facing regulatory bodies included complicated adverse drug reactions (ADR) reporting forms, lack of feedback on ADRs submitted to the Saudi Food and Drug Authority, lack of decisions from the local authority to withdraw medications, and lack of data on pharmacovigilance. The challenges to pharmacovigilance in hospitals included the lack of knowledge of the significance of ADR reporting, workload, blaming culture, and lack of collaboration between regulatory bodies and hospitals. However, challenges facing pharmaceutical industries included the lack of drug manufacturers in Saudi Arabia and lack of interest in pharmacovigilance. Recommendations to improve pharmacovigilance included the need for communication, stronger regulatory requirements, the need for research, the need for unified ADRs reporting, and continuous education and training.  The study has identified the challenges facing pharmacovigilance in Saudi Arabia and made certain recommendations to overcome them. These recommendations might be helpful for regulatory bodies to enhance spontaneous reporting and promote pharmacovigilance.

Modern-Day Demographic Processes in Central Europe and Their Potential Interactions with Climate Change

NASA Astrophysics Data System (ADS)

Bański, Jerzy

2013-01-01

The aim of this article is to evaluate the effect of contemporary transformations in the population of Central European countries on climate change, in addition to singling out the primary points of interaction between demographic processes and the climate. In analyzing the interactions between climate and demographics, we can formulate three basic hypotheses regarding the region in question: 1) as a result of current demographic trends in Central Europe, the influence of the region on its climate will probably diminish, 2) the importance of the "climatically displaced" in global migratory movements will increase, and some of those concerned will move to Central Europe, 3) the contribution of the region to global food security will increase. In the last decade most of what comprises the region of Central Europe has reported a decline in population growth and a negative migration balance. As a process, this loss of population may have a positive effect on the environment and the climate. We can expect ongoing climate change to intensify migration processes, particularly from countries outside Europe. Interactions between climate and demographic processes can also be viewed in the context of food security. The global warming most sources foresee for the coming decades is the process most likely to result in spatial polarization of food production in agriculture. Central Europe will then face the challenge of assuring and improving food security, albeit this time on a global scale.

Toward a Social Psychophysics of Face Communication.

PubMed

Jack, Rachael E; Schyns, Philippe G

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.

Climate Change Adaptation Challenges and EO Business Opportunities

Lopez-Baeza, Ernesto; Mathieu, Pierre-Philippe; Bansal, Rahul; Del Rey, Maria; Mohamed, Ebrahim; Ruiz, Paz; Signes, Marcos

Climate change is one of the defining challenges of the 21st century, but is no longer a matter of just scientific concern. It encompasses economics, sociology, global politics as well as national and local politics, law, health and environmental security, etc. The challenge of facing the impacts of climate change is often framed in terms of two potential paths that civilization might take: mitigation and adaptation. On the one hand, mitigation involves reducing the magnitude of climate change itself and is composed of emissions reductions and geoengineering. On the other hand and by contrast, adaptation involves efforts to limit our vulnerability to climate change impacts through various measures. It refers to our ability to adjust ourselves to climate change -including climate variability and extremes, to moderate potential damage, to take advantage of opportunities, or to cope with the consequences. Therefore, we are now faced with a double challenge: next to deep cuts in greenhouse gas emissions, we also need to adapt to the changing climate conditions. The use of satellites to monitor processes and trends at the global scale is essential in the context of climate change. Earth Observation has the potential to improve our predictive vision and to advance climate models. Space sciences and technologies constitute a significant issue in Education and Public Awareness of Science. Space missions face the probably largest scientific and industrial challenges of humanity. It is thus a fact that space drives innovation in the major breakthrough and cutting edge technological advances of mankind (techniques, processes, new products, … as well as in markets and business models). Technology and innovation is the basis of all space activities. Space agencies offer an entire range of space-related activities - from space science and environmental monitoring to industrial competitiveness and end-user services. More specifically, Earth Observation satellites have a unique global view of planet Earth, providing us -with better data- with consistent and frequent information on the state of our environment at the regional and global scale, also in important but remote areas. Climate Knowledge and Innovation Communities (Climate-KIC), a relatively new initiative from the European Institute of Innovation & Technology (EIT), provides the innovations, entrepreneurship, education and expert guidance needed to shape Europe's climate change agenda. This paper shows some initiatives that the University of Valencia Climate-KIC Education Group is carrying out in collaboration with the Climate-KIC Central Education Lead in the field of space education to foster and encourage students and entrepreneurs to endevour in these new space business opportunities offered by this step forward towards climate change adaptation challenges.

Pose-Invariant Face Recognition via RGB-D Images.

PubMed

Sang, Gaoli; Li, Jing; Zhao, Qijun

2016-01-01

Three-dimensional (3D) face models can intrinsically handle large pose face recognition problem. In this paper, we propose a novel pose-invariant face recognition method via RGB-D images. By employing depth, our method is able to handle self-occlusion and deformation, both of which are challenging problems in two-dimensional (2D) face recognition. Texture images in the gallery can be rendered to the same view as the probe via depth. Meanwhile, depth is also used for similarity measure via frontalization and symmetric filling. Finally, both texture and depth contribute to the final identity estimation. Experiments on Bosphorus, CurtinFaces, Eurecom, and Kiwi databases demonstrate that the additional depth information has improved the performance of face recognition with large pose variations and under even more challenging conditions.

The organization of organ procurement.

PubMed

Prottas, J M

1989-01-01

The American organ procurement system has improved and matured in the last five years. At the same time, the basic challenges facing it have remained substantially the same because the moral and legal framework of the system has not changed. Success at organ procurement continues to depend on the voluntary cooperation of medical professionals and the families of potential organ donors. The generosity of the American public is so great that the primary challenge facing organ procurement agencies is obtaining cooperation from hospitals and medical professionals. This calls for a "marketing" orientation aimed at those hospitals and professionals who are most likely to treat potential donors. The last five years have seen a more general acceptance of this appreciation of the central task of organ procurement. As a result, the overall effectiveness of the system has improved, as measured by the number of organs procured on a per capita basis and by the number of multiorgan donors obtained. Much of this improvement can be attributed to the diffusion of organizational techniques and approaches, and this diffusion has been encouraged by the involvement of national organizations and public bodies in the organ procurement community. The system remains uneven in its effectiveness and further improvement is possible. It is also possible that the next general round of improvement will result from the application of businesslike information management and marketing techniques.

The CMS Remote Analysis Builder (CRAB) is a distributed workflow management tool which facilitates analysis tasks by isolating users from the technical details of the Grid infrastructure. Throughout LHC Run 1, CRAB has been successfully employed by an average of 350 distinct users each week executing about 200,000 jobs per day. CRAB has been significantly upgraded in order to face the new challenges posed by LHC Run 2. Components of the new system include 1) a lightweight client, 2) a central primary server which communicates with the clients through a REST interface, 3) secondary servers which manage user analysis tasks and submit jobs to the CMS resource provisioning system, and 4) a central service to asynchronously move user data from temporary storage in the execution site to the desired storage location. The new system improves the robustness, scalability and sustainability of the service. Here we provide an overview of the new system, operation, and user support, report on its current status, and identify lessons learned from the commissioning phase and production roll-out.

Challenges for nurses who work in community mental health centres in the West Bank, Palestine.

Marie, Mohammad; Hannigan, Ben; Jones, Aled

2017-01-01

Nurses in Palestine (occupied Palestinian territory) work in a significantly challenging environment. The mental health care system is underdeveloped and under-resourced. For example, the total number of nurses who work in community mental health centres in the West Bank is seventeen, clearly insufficient in a total population of approximately three million. This research explored daily challenges that Palestinian community mental health nurses (CMHNs) face within and outside their demanding workplaces. An interpretive qualitative design was chosen. Face-to-face interviews were completed with fifteen participants. Thirty-two hours of observations of the day-to-day working environment and workplace routines were conducted in two communities' mental health centres. Written documents relating to practical job-related policies were also collected from various workplaces. Thematic analysis was used across all data sources resulting in four main themes, which describe the challenges faced by CMHNs. These themes consist of the context of unrest, stigma, lack of resources, and organisational or mental health system challenges. The study concludes with a better understanding of challenges in nursing which draws on wider cultural contexts and resilience. The outcomes from this study can be used to decrease the challenges for health professionals and enhance the mental health care system in Palestine.

Monitoring tropical deforestation and forest degradation is one of the central elements for the Reduced Emissions from Deforestation and Forest Degradation in developing countries (REDD+) scheme. Current arrangements for monitoring are based on remote sensing and field measurements. Since monitoring is the periodic process of assessing forest stands properties with respect to reference data, adopting the current REDD+ requirements for implementing monitoring at national levels is a challenging task. Recently, the advancement in Information and Communications Technologies (ICT) and mobile devices has enabled local communities to monitor their forest in a basic resource setting such as no or slow internet connection link, limited power supply, etc. Despite the potential, the use of mobile device system for community based monitoring (CBM) is still exceptional and faces implementation challenges. This paper presents an integrated data collection system based on mobile devices that streamlines the community-based forest monitoring data collection, transmission and visualization process. This paper also assesses the accuracy and reliability of CBM data and proposes a way to fit them into national REDD+ Monitoring, Reporting and Verification (MRV) scheme. The system performance is evaluated at Tra Bui commune, Quang Nam province, Central Vietnam, where forest carbon and change activities were tracked. The results show that the local community is able to provide data with accuracy comparable to expert measurements (index of agreement greater than 0.88), but against lower costs. Furthermore, the results confirm that communities are more effective to monitor small scale forest degradation due to subsistence fuel wood collection and selective logging, than high resolution remote sensing SPOT imagery.

Focused Ultrasound Immunotherapy for Central Nervous System Pathologies: Challenges and Opportunities

PubMed Central

Curley, Colleen T.; Sheybani, Natasha D.; Bullock, Timothy N.; Price, Richard J.

2017-01-01

Immunotherapy is rapidly emerging as the cornerstone for the treatment of several forms of metastatic cancer, as well as for a host of other pathologies. Meanwhile, several new high-profile studies have uncovered remarkable linkages between the central nervous and immune systems. With these recent developments, harnessing the immune system for the treatment of brain pathologies is a promising strategy. Here, we contend that MR image-guided focused ultrasound (FUS) represents a noninvasive approach that will allow for favorable therapeutic immunomodulation in the setting of the central nervous system. One obstacle to effective immunotherapeutic drug delivery to the brain is the blood brain barrier (BBB), which refers to the specialized structure of brain capillaries that prevents transport of most therapeutics from the blood into brain tissue. When applied in the presence of circulating microbubbles, FUS can safely and transiently open the BBB to facilitate the delivery of immunotherapeutic agents into the brain parenchyma. Furthermore, it has been demonstrated that physical perturbations of the tissue microenvironment via FUS can modulate immune response in both normal and diseased tissue. In this review article, we provide an overview of FUS energy regimens and corresponding tissue bioeffects, followed by a review of the literature pertaining to FUS for therapeutic antibody delivery in normal brain and preclinical models of brain disease. We provide an overview of studies that demonstrate FUS-mediated immune modulation in both the brain and peripheral settings. Finally, we provide remarks on challenges facing FUS immunotherapy and opportunities for future expansion in this area. PMID:29109764

The purpose of this study was to explore challenges faced by patients with systemic sclerosis, also called scleroderma, in coping with their disease and the strategies they used to face those challenges. Five focus groups were held with scleroderma patients (4 groups, n = 34) and health care professionals who have experience treating scleroderma (1 group, n = 8). Participants' discussions were recorded, transcribed and analyzed using thematic analysis. Participants reported challenges accessing information (e.g., knowledgeable specialists), dealing with negative emotions (e.g., stress due to misunderstandings with loved ones), and accessing resources (e.g., helpful products or devices). Strategies for overcoming challenges were also discussed (e.g., advocating for own needs). When faced with significant challenges while coping with scleroderma, patients develop strategies to manage better and improve their quality of life. To help them cope, patients would benefit from easier access to supportive interventions, including tailored scleroderma self-management programs. Although the challenges experienced by patients with scleroderma are unique, findings from this study might help better understand patients' perspectives regarding coping and disease management for other chronic diseases as well. Implications for Rehabilitation People living with rare diseases, including the rare autoimmune disease scleroderma, face unique challenges and often do not have access to disease-specific educational or other support resources. People with scleroderma report that they face challenges in accessing information, including knowledgeable healthcare providers; managing difficult social interactions and negative emotions; and accessing resources. Strategies employed by scleroderma patients to overcome these challenges include seeking connections to other people with scleroderma or scleroderma patient organizations, actively seeking out local resources, and learning to communicate and advocate more effectively. Rehabilitation professionals can support people with scleroderma by providing them with information on connecting with scleroderma patient organizations or by facilitating local patient support networks.

Challenges newly-arrived migrant women in Montreal face when needing maternity care: Health care professionals' perspectives.

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.

Looking at faces from different angles: Europeans fixate different features in Asian and Caucasian faces.

PubMed

Brielmann, Aenne A; Bülthoff, Isabelle; Armann, Regine

2014-07-01

Race categorization of faces is a fast and automatic process and is known to affect further face processing profoundly and at earliest stages. Whether processing of own- and other-race faces might rely on different facial cues, as indicated by diverging viewing behavior, is much under debate. We therefore aimed to investigate two open questions in our study: (1) Do observers consider information from distinct facial features informative for race categorization or do they prefer to gain global face information by fixating the geometrical center of the face? (2) Does the fixation pattern, or, if facial features are considered relevant, do these features differ between own- and other-race faces? We used eye tracking to test where European observers look when viewing Asian and Caucasian faces in a race categorization task. Importantly, in order to disentangle centrally located fixations from those towards individual facial features, we presented faces in frontal, half-profile and profile views. We found that observers showed no general bias towards looking at the geometrical center of faces, but rather directed their first fixations towards distinct facial features, regardless of face race. However, participants looked at the eyes more often in Caucasian faces than in Asian faces, and there were significantly more fixations to the nose for Asian compared to Caucasian faces. Thus, observers rely on information from distinct facial features rather than facial information gained by centrally fixating the face. To what extent specific features are looked at is determined by the face's race. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

International involvement and national health governance: the basic benefit package in Tajikistan.

Rechel, Bernd; Khodjamurodov, Ghafur

Tajikistan, a Central Asian state of 7.4 million inhabitants, is facing particular health policy challenges: not only is the country the poorest of the former Soviet republics, but its capacity to deal with post-communist transition and economic crisis has been further undermined through civil war and large-scale migration. This paper, examining the introduction of the basic benefit package and formal co-payments, elucidates how international involvement in Tajikistan's health sector has impacted on national health governance. Based on documentary sources and information provided by key informants, we find that external agencies have both strengthened and weakened national health governance. Although they have played a major part in supporting Tajikistan's health sector, these efforts have often been fragmented, as donor coordination was at times less than optimal. A key challenge for national health governance is the limited technical and institutional capacity of the Ministry of Health and further efforts are needed to build national capacity.

Theranostic quantum dots for crossing blood–brain barrier in vitro and providing therapy of HIV-associated encephalopathy

PubMed Central

2013-01-01

The blood–brain barrier (BBB) is a complex physiological checkpoint that restricts the free diffusion of circulating molecules from the blood into the central nervous system. Delivering of drugs and other active agents across the BBB is one of the major technical challenges faced by scientists and medical practitioners. Therefore, development of novel methodologies to address this challenge holds the key for both the diagnosis and treatment of brain diseases, such as HIV-associated encephalopathy. Bioconjugated quantum dots (QDs) are excellent fluorescent probes and nano-vectors, being designed to transverse across the BBB and visualize drug delivery inside the brain. This paper discusses the use of functionalized QDs for crossing the blood–brain barrier and treating brain disease. We highlight the guidelines for using in vitro BBB models for brain disease studies. The theranostic QDs offers a strategy to significantly improve the effective dosages of drugs to transverse across the BBB and orientate to the targets inside the brain. PMID:24298256

Teng, T; Shao, Y

2011-04-01

The HIV epidemic in China started among intravenous drug users in the late 1980s. The second wave of the epidemic was caused by an outbreak in the paid plasma donors in central China in the mid-1990s. Sexually transmitted HIV cases have steadily increased and comprised more than half the reported HIV/AIDS infections since 2007. In the last 5 years, there has been a sharp increase of HIV infection in men who have sex with men. The HIV epidemic in China has expanded from high-risk groups to the general population and from rural regions to urban areas. This brief article discusses the history of HIV epidemics in China and the challenges facing the current AIDS control efforts in the country. It explains that only scientific approaches can sustain the national AIDS control programs and introduce the type of research needed to address those challenges. The selected research areas include molecular epidemiology, drug resistance surveillance, and the Chinese HIV vaccine research.

Multilevel water governance and problems of scale: setting the stage for a broader debate.

PubMed

Moss, Timothy; Newig, Jens

2010-07-01

Environmental governance and management are facing a multiplicity of challenges related to spatial scales and multiple levels of governance. Water management is a field particularly sensitive to issues of scale because the hydrological system with its different scalar levels from small catchments to large river basins plays such a prominent role. It thus exemplifies fundamental issues and dilemmas of scale in modern environmental management and governance. In this introductory article to an Environmental Management special feature on "Multilevel Water Governance: Coping with Problems of Scale," we delineate our understanding of problems of scale and the dimensions of scalar politics that are central to water resource management. We provide an overview of the contributions to this special feature, concluding with a discussion of how scalar research can usefully challenge conventional wisdom on water resource management. We hope that this discussion of water governance stimulates a broader debate and inquiry relating to the scalar dimensions of environmental governance and management in general.

Pilates and pregnancy.

PubMed

Balogh, Adi

2005-05-01

Pregnancy is associated with a number of musculoskeletal problems. It is important to educate all mothers, as well as those involved in ante- and postnatal care with advice on bras and exercises that are safe in pregnancy (in particular pelvic floor exercises). There is not much that can be done to alter the inevitable physiological and hormonal changes of pregnancy. However, by strengthening the core stabilising muscles around the pelvis and spine, and improving the breathing pattern, it is hoped that one can optimise the body for the challenges it may face. Pilates is based on the principle that a central core is developed and then movements are introduced to challenge this core stability. This philosophy is clearly applicable in pregnancy--a significant test both mentally and physically on the mother's body. By maximising the mother's core stability before and during pregnancy, it should be possible to limit any potential harm. Returning to exercise soon after the birth is important for the mother's physical and mental wellbeing--she looks after her baby's body for nine months, who cares for hers?

Urban infrastructure and water management—Science capabilities of the U.S. Geological Survey

Fisher, Shawn C.; Fanelli, Rosemary M.; Selbig, William R.

2016-04-29

Managing the urban-water cycle has increasingly become a challenge for water-resources planners and regulators faced with the problem of providing clean drinking water to urban residents. Sanitary and combined sanitary and storm sewer networks convey wastewater to centralized treatment plants. Impervious surfaces, which include roads, parking lots, and buildings, increase stormwater runoff and the efficiency by which runoff is conveyed to nearby stream channels; therefore, impervious surfaces increase the risk of urban flooding and alteration of natural ecosystems. These challenges will increase with the expansion of urban centers and the probable effects of climate change on precipitation patterns. Understanding the urban-water cycle is critical to effectively manage water resources and to protect people, infrastructure, and urban-stream ecosystems. As a leader in water-supply, wastewater, and stormwater assessments, the U.S. Geological Survey has the expertise and resources needed to monitor, model, and interpret data related to the urban-water cycle and thereby enable water-resources managers to make informed decisions.

The New Challenges of China's South to North Water Diversion Project

NASA Astrophysics Data System (ADS)

Liu, X.

2017-12-01

Water shortage has restricted the economic and social development of Beijing during recent years. The central route of China's South to North Water Diversion Project is planned to divert water from the Danjiangkou Reservoir to Beijing. Currently, the main local surface water source for Beijing is the Miyun Reservoir. We found that annual runoffs in both of the Danjiangkou Reservoir Basin and Miyun Reservoir Basin decreased significantly from 1956 to 2015. The decrease in runoff represents a decrease in available water resources. We classified each year between 1956 and 2015 as either a wet, normal or dry year based on the Pearson-III probability distribution of annual runoff. The probability of a simultaneous dry year in the two basins was about 8.8% during 1956 to 1989, while it increased to 33.7% during 1990 to 2015. The increase in probability of a simultaneous dry year could threaten the success of the water diversion project. We suggest that urgent adaptive measures are implemented in advance to face this challenge.

Threshold concepts in finance: conceptualizing the curriculum

2015-08-01

Graduates with well-developed capabilities in finance are invaluable to our society and in increasing demand. Universities face the challenge of designing finance programmes to develop these capabilities and the essential knowledge that underpins them. Our research responds to this challenge by identifying threshold concepts that are central to the mastery of finance and by exploring their potential for informing curriculum design and pedagogical practices to improve student outcomes. In this paper, we report the results of an online survey of finance academics at multiple institutions in Australia, Canada, New Zealand, South Africa and the United Kingdom. The outcomes of our research are recommendations for threshold concepts in finance endorsed by quantitative evidence, as well as a model of the finance curriculum incorporating finance, modelling and statistics threshold concepts. In addition, we draw conclusions about the application of threshold concept theory supported by both quantitative and qualitative evidence. Our methodology and findings have general relevance to the application of threshold concept theory as a means to investigate and inform curriculum design and delivery in higher education.

This pilot study used the framework of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) to understand the challenges faced by Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans as they reintegrate into the community. We conducted semistructured interviews with 14 injured veterans, 12 caregivers, and 14 clinicians. We used ICF taxonomy to code data and identify issues. We identified challenges in the following ICF domains: learning and applying knowledge; general tasks and demands; communication; mobility; self-care; domestic life; interpersonal interactions, major life areas; and community, social, and civic life. We found many similarities between the challenges faced by veterans with and without polytraumatic injuries, although veterans with polytraumatic injuries faced challenges of greater magnitude. Identifying community reintegration challenges early and promoting reintegration are important mandates for the Department of Veterans Affairs. The findings of this study are useful in understanding the needs of OEF/OIF veterans.

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. PMID:27613779

The aims of this research were to determine extra-organisational challenges (e.g. market competition, governing policies) faced by community pharmacies in Sarawak, the coping strategies employed to deal with these challenges and explore potential legislative changes that can attenuate the intensity of these challenges. Survey questionnaires (n = 184) were posted to all eligible community pharmacies in Sarawak, Malaysia. The questionnaire included sections on participants' demographic data, extra-organisational challenges faced, coping strategies employed and proposals to improve community pharmacy legislations. Items were constructed based on the findings of a prior qualitative research supplemented with relevant literature about these issues. High levels of homogeneity in responses were recorded on various extra-organisational challenges faced, particularly those economy-oriented. Strategic changes to counter these challenges were focused on pricing and product stocked, rather than services provision. Highly rated strategies included increasing discounts for customers (n = 54; 68%) and finding cheaper suppliers (n = 70; 88%). Legislative changes proposed that might increase their share of the pharmaceutical market were strongly supported by respondents, particularly about making it compulsory for general practitioners to provide patients the option to have their medicines dispensed in community pharmacies (n = 72; 90%). Current legislative conditions and Malaysian consumer mindset may have constrained the strategic choices of community pharmacies to deal with the strong extra-organisational challenges. A long-term multipronged approach to address these issues and increased involvement of community pharmacists themselves in this agenda are required to influence practice change. © 2018 Royal Pharmaceutical Society.

Addressing HIV/AIDS challenges in Uganda: does social capital generation by NGOs matter?

Muriisa, Roberts Kabeba; Jamil, Ishtiaq

2011-01-01

HIV/AIDS has had devastating impacts in many countries, Uganda in particular. However, Uganda is depicted as one of the most successful countries in fighting HIV/AIDS. Among others, Uganda's success story is attributed to the open general environment which allows open discussions surrounding HIV/AIDS when other countries such as South Africa and Kenya denied the existence of the disease in their countries. In addition, the success is attributed to the policy which allowed many actors to participate in the fight against the disease. The primary focus of this article is to map the process of social capital generation by NGOs and how social capital benefits enhance mitigation of HIV/AIDS challenges in Uganda. The key to social capital is nurturing relationships. In this regard, HIV/AIDS NGOs play a central role in the way individuals, groups and communities interact, and how various kinds of social relations are forged with people living with HIV/AIDS and especially for those who are HIV infected. NGOs' success in reducing the number of HIV/AIDS cases in Uganda is based on their abilities to generate social capital. This involves inclusion and building social networks and empowerment at the individual and community levels, and disseminating information to reduce social stigma as well as discrimination. We used a mixed-method strategy to collect data for this study. We used a structured questionnaire having quantitative and qualitative question sets which focused on different social capital measurement indicators. We used observations and in-depth face-to-face interviews. A major finding of the study is that the ways individuals and groups are connected and interact with each other are important mechanisms for alleviating HIV/AIDS challenges in Uganda.

This article presents the scientific evidence for the merits of telemedicine interventions in primary care. Although there is no uniform and consistent definition of primary care, most agree that it occupies a central role in the healthcare system as first contact for patients seeking care, as well as gatekeeper and coordinator of care. It enables and supports patient-centered care, the medical home, managed care, accountable care, and population health. Increasing concerns about sustainability and the anticipated shortages of primary care physicians have sparked interest in exploring the potential of telemedicine in addressing many of the challenges facing primary care in the United States and the world. The findings are based on a systematic review of scientific studies published from 2005 through 2015. The initial search yielded 2,308 articles, with 86 meeting the inclusion criteria. Evidence is organized and evaluated according to feasibility/acceptance, intermediate outcomes, health outcomes, and cost. The majority of studies support the feasibility/acceptance of telemedicine for use in primary care, although it varies significantly by demographic variables, such as gender, age, and socioeconomic status, and telemedicine has often been found more acceptable by patients than healthcare providers. Outcomes data are limited but overall suggest that telemedicine interventions are generally at least as effective as traditional care. Cost analyses vary, but telemedicine in primary care is increasingly demonstrated to be cost-effective. Telemedicine has significant potential to address many of the challenges facing primary care in today's healthcare environment. Challenges still remain in validating its impact on clinical outcomes with scientific rigor, as well as in standardizing methods to assess cost, but patient and provider acceptance is increasingly making telemedicine a viable and integral component of primary care around the world.

Abstract Introduction: This article presents the scientific evidence for the merits of telemedicine interventions in primary care. Although there is no uniform and consistent definition of primary care, most agree that it occupies a central role in the healthcare system as first contact for patients seeking care, as well as gatekeeper and coordinator of care. It enables and supports patient-centered care, the medical home, managed care, accountable care, and population health. Increasing concerns about sustainability and the anticipated shortages of primary care physicians have sparked interest in exploring the potential of telemedicine in addressing many of the challenges facing primary care in the United States and the world. Materials and Methods: The findings are based on a systematic review of scientific studies published from 2005 through 2015. The initial search yielded 2,308 articles, with 86 meeting the inclusion criteria. Evidence is organized and evaluated according to feasibility/acceptance, intermediate outcomes, health outcomes, and cost.

Optimal web investment in sub-optimal foraging conditions.

Harmer, Aaron M T; Kokko, Hanna; Herberstein, Marie E; Madin, Joshua S

2012-01-01

Orb web spiders sit at the centre of their approximately circular webs when waiting for prey and so face many of the same challenges as central-place foragers. Prey value decreases with distance from the hub as a function of prey escape time. The further from the hub that prey are intercepted, the longer it takes a spider to reach them and the greater chance they have of escaping. Several species of orb web spiders build vertically elongated ladder-like orb webs against tree trunks, rather than circular orb webs in the open. As ladder web spiders invest disproportionately more web area further from the hub, it is expected they will experience reduced prey gain per unit area of web investment compared to spiders that build circular webs. We developed a model to investigate how building webs in the space-limited microhabitat on tree trunks influences the optimal size, shape and net prey gain of arboricolous ladder webs. The model suggests that as horizontal space becomes more limited, optimal web shape becomes more elongated, and optimal web area decreases. This change in web geometry results in decreased net prey gain compared to webs built without space constraints. However, when space is limited, spiders can achieve higher net prey gain compared to building typical circular webs in the same limited space. Our model shows how spiders optimise web investment in sub-optimal conditions and can be used to understand foraging investment trade-offs in other central-place foragers faced with constrained foraging arenas.

Vu Gia- Thu Bon (VGTB) River Basin, located in the Central Coastal zone of Viet Nam currently faces water shortage. Climate change is expected to exacerbate the challenge. Therefore, there is a need to study the impacts of climate change on water shortage in the river basin. The study adopts a combined top-down and bottom-up climate change impact assessment to address the impacts of climate change on water shortage in the VGTB River Basin. A MIKE BASIN water balance model for the river basin was established to simulate the response of the hydrological system. Simulations were performed through parametrically varying temperature and precipitation to determine the vulnerability space of water shortage. General Circulation Models (GCMs) were then utilized to provide climate projections for the river basin. The output from GCMs was then mapped onto the vulnerability space determined earlier. In total, 9 out of 55 water demand nodes in the simulation are expected to face problematic conditions as future climate changes. Copyright © 2018 Elsevier B.V. All rights reserved.

Trade-off between light availability and soil fertility determine refugial conditions for the relict light-demanding species in lowland forests

2017-11-01

Identifying potential refugial habitats in the face of rapid environmental change is a challenge faced by scientists and nature conservation managers. Relict populations and refugial habitats are the model objects in those studies. Based on the example of Actaea europaea from Central Poland, we analyse the habitat factors influencing relict populations of continental, light-demanding species in lowland forests and examine which habitats of studied species corresponding most closely to ancient vegetation. Our results indicate that the current refugial habitats of Actaea europaea include not only communities which are very similar to ancient open forest but also forests with a closed canopy. Although the populations are influenced by nitrogen and light availability, the co-occurrence of these two factors in forest communities is limited by dense canopy formation by hornbeam and beech trees on fertile soils and in more humid conditions. Our findings indicate that the future survival of relict, light-demanding communities in lowland forests requires low-intensity disturbances to be performed in tree-stands, according to techniques, which imitate traditional forests management.

Within the last decade, abstract argumentation has emerged as a central field in Artificial Intelligence. Besides providing a core formalism for many advanced argumentation systems, abstract argumentation has also served to capture several non-monotonic logics and other AI related principles. Although the idea of abstract argumentation is appealingly simple, several reasoning problems in this formalism exhibit high computational complexity. This calls for advanced techniques when it comes to implementation issues, a challenge which has been recently faced from different angles. In this survey, we give an overview on different methods for solving reasoning problems in abstract argumentation and compare their particular features. Moreover, we highlight available state-of-the-art systems for abstract argumentation, which put these methods to practice. PMID:25737590

External occulters, otherwise known as starshades, have been proposed as a solution to one of the highest priority yet technically vexing problems facing astrophysics-the direct imaging and characterization of terrestrial planets around other stars. New apodization functions, developed over the past few years, now enable starshades of just a few tens of meters diameter to occult central stars so efficiently that the orbiting exoplanets can be revealed and other high-contrast imaging challenges addressed. In this paper, an analytic approach to the analysis of these apodization functions is presented. It is used to develop a tolerance analysis suitable for use inmore » designing practical starshades. The results provide a mathematical basis for understanding starshades and a quantitative approach to setting tolerances.« less

Integrating bioethics into postgraduate medical education: the University of Toronto model.

PubMed

Howard, Frazer; McKneally, Martin F; Levin, Alex V

2010-06-01

Bioethics training is a vital component of postgraduate medical education and required by accreditation organizations in Canada and the United States. Residency program ethics curricula should ensure trainees develop core knowledge, skills, and competencies, and should encourage lifelong learning and teaching of bioethics. Many physician-teachers, however, feel unprepared to teach bioethics and face challenges in developing and implementing specialty-specific bioethics curricula. The authors present, as one model, the innovative strategies employed by the University of Toronto Joint Centre for Bioethics. They postulate that centralized support is a key component to ensure the success of specialty-specific bioethics teaching, to reinforce the importance of ethics in medical training, and to ensure it is not overshadowed by other educational concerns.

A reflection on whether to expose, determine and clarify the effects of marijuana on pregnant adolescents and their fetus is a determining factor to consider more judiciously the tendency to legalize marijuana in Mexico. We emphasize alterations in the central nervous system, immune system and some genetic aspects of the fetus and its potential expressions at different stages of a child's life. Should pediatricians and parents allow, in addition to the difficulties that their patients and children face today, the risk that is the affordability of marijuana? That is the challenge to overcome. Copyright © 2014 Hospital Infantil de México Federico Gómez. Publicado por Masson Doyma México S.A. All rights reserved.

Designing molecular p-n heterojunction structures, i.e., electron donor-acceptor contacts, is one of the central challenges for further development of organic electronic devices. In the present study, a well-defined p-n heterojunction of two representative molecular semiconductors, pentacene and C60, formed on the single-crystal surface of pentacene is precisely investigated in terms of its growth behavior and crystallographic structure. C60 assembles into a (111)-oriented face-centered-cubic crystal structure with a specific epitaxial orientation on the (001) surface of the pentacene single crystal. The present experimental findings provide molecular scale insights into the formation mechanisms of the organic p-n heterojunction through an accurate structural analysis of the single-crystalline molecular contact.

Measuring and modeling the integrated behavior of biomolecular-cellular networks is central to systems biology. Over several decades, systems biology has been shaped by quantitative biologists, physicists, mathematicians, and engineers in different ways. However, the basic and applied versions of systems biology are not typically distinguished, which blurs the separate aspirations of the field and its potential for real-world impact. Here, we articulate an engineering approach to systems biology, which applies educational philosophy, engineering design, and predictive models to solve contemporary problems in an age of biomedical Big Data. A concerted effort to train systems bioengineers will provide a versatile workforce capable of tackling the diverse challenges faced by the biotechnological and pharmaceutical sectors in a modern, information-dense economy.

Neonatal Neurobehavioral and Neuroanatomic Correlates of Prenatal Cocaine Exposure

Complex methodologic challenges face researchers studying the effects of prenatal cocaine exposure on infant outcome. These include unavoidable imprecision in ascertaining the gestational timing and dose of cocaine to which the fetus was exposed and difficulties in identifying and quantifying the confounding, mediating, and moderating variables. Review of research on neonatal behavioral and cranial ultrasound findings following in utero cocaine exposure is used to illustrate these issues. We conclude that there are measurable but not dramatic dose-related effects of prenatal cocaine exposure on infant central nervous system structure and function. The effects of dose of prenatal cocaine exposure on later child development remain to be determined. Such research would be facilitated by a scientific consensus delineating relative doses of prenatal cocaine exposure. PMID:9668396

Potential effects of drought on carrying capacity for wintering waterfowl in the Central Valley of California

Petrie, Mark J.; Fleskes, Joseph P.; Wolder, Mike A.; Isola, Craig R.; Yarris, Gregory S.; Skalos, Daniel A.

2016-01-01

We used the bioenergetics model TRUEMET to evaluate potential effects of California's recent drought on food supplies for waterfowl wintering in the Central Valley under a range of habitat and waterfowl population scenarios. In nondrought years in the current Central Valley landscape, food supplies are projected to be adequate for waterfowl from fall through early spring (except late March) even if waterfowl populations reach North American Waterfowl Management Plan goals. However, in all drought scenarios that we evaluated, food supplies were projected to be exhausted for ducks by mid- to late winter and by late winter or early spring for geese. For ducks, these results were strongly related to projected declines in winter-flooded rice fields that provide 45% of all the food energy available to ducks in the Central Valley in nondrought water years. Delayed flooding of some managed wetlands may help alleviate food shortages by providing wetland food resources better timed with waterfowl migration and abundance patterns in the Central Valley, as well as reducing the amount of water needed to manage these habitats. However, future research is needed to evaluate the impacts of delayed flooding on waterfowl hunting, and whether California's existing water delivery system would make delayed flooding feasible. Securing adequate water supplies for waterfowl and other wetland-dependent birds is among the greatest challenges facing resource managers in coming years, especially in the increasingly arid western United States.

2013-01-01

Background During the 1990s, the government of Tanzania introduced the decentralization by devolution (D by D) approach involving the transfer of functions, power and authority from the centre to the local government authorities (LGAs) to improve the delivery of public goods and services, including health services. Objective This article examines and documents the experiences facing the implementation of decentralization of health services from the perspective of national and district officials. Design The study adopted a qualitative approach, and data were collected using semi-structured interviews and were analysed for themes and patterns. Results The results showed several benefits of decentralization, including increased autonomy in local resource mobilization and utilization, an enhanced bottom-up planning approach, increased health workers’ accountability and reduction of bureaucratic procedures in decision making. The findings also revealed several challenges which hinder the effective functioning of decentralization. These include inadequate funding, untimely disbursement of funds from the central government, insufficient and unqualified personnel, lack of community participation in planning and political interference. Conclusion The article concludes that the central government needs to adhere to the principles that established the local authorities and grant more autonomy to them, offer special incentives to staff working in the rural areas and create the capacity for local key actors to participate effectively in the planning process.

As the next generation of scientists enters the field of environmental health, it is imperative that they view their contributions in the context of global environmental stewardship. In this commentary, a group of international graduate students facilitated by three experienced environmental health scientists present their views on what they consider to be the global environmental health concerns of today. This group convened initially in October 2004 at an international health conference in Prague, Czech Republic. In this report we identify perceived environmental health concerns that exist around the world, with a focus on Central and Eastern Europe. Additionally, we address these perceived problems and offers some potential solutions. At the meeting, students were invited to participate in two panel discussions. One group of young international scientists identified several significant global environmental health concerns, including air pollution, occupational hazards, and risk factors that may exacerbate current environmental health issues. The second panel determined that communication, education, and regulation were the mechanisms for addressing current environmental challenges. In this commentary we expand on the views presented at the meeting and represent the concerns of young investigators from nine different countries. We provide ideas about and support the exchange of information between developed and developing countries on how to handle the environmental health challenges that face the world today.

Missed Opportunities for Science Learning: Unacknowledged Unscientific Arguments in Asynchronous Online and Face-to-Face Discussions

2018-02-01

We explored the scientific argumentation that occurs among university biology students during an argumentation task implemented in two environments: face-to-face in a classroom and online in an asynchronous discussion. We observed 10 student groups, each composed of three students. Our analysis focused on how students respond to their peers' unscientific arguments, which we define as assertions, hypotheses, propositions, or explanations that are inaccurate or incomplete from a scientific perspective. Unscientific arguments provide opportunities for productive dissent, scientific argumentation, and conceptual development of scientifically desirable conceptions. We found that students did not respond to the majority of unscientific arguments in both environments. Challenges to unscientific arguments were expressed as a question or through explanation, although the latter was more common online than face-to-face. Students demonstrated significantly more epistemic distancing in the face-to-face environment than the online environment. We discuss the differences in discourse observed in both environments and teaching implications. We also provide direction for future research seeking to address the challenges of engaging students in productive scientific argumentation in both face-to-face and online environments.

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

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. More disability-related cultural competence and patient-centred training for healthcare providers as well as the provision of disability-friendly transport and healthcare facilities and services are needed.

Background 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. Methods and Findings 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. Conclusions 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.

Boulder, Colorado is a central hub of climate research and education resources, yet teachers less than two hours away struggle to find relevant climate curriculum and meaningful connections to climate scientists. Learn More About Climate (LMAC), an initiative of the CU-Boulder Office for Outreach and Engagement was created to provide access to the most up-to-date scientific research in a user-friendly way that raises awareness and inspires an informed dialogue about climate change among Coloradans. LMAC produces classroom ready videos highlighting CU climate scientists, offers classroom visits and Skype sessions with scientists, and serves as a hub for the most recent climate news. LMAC recently formed a Teacher Advisory Board made up of eleven K12 teachers from across Colorado spanning rural, suburban, and urban school districts. Given different locations, demographics, and grade levels, each teacher faces different challenges teaching climate. Here we present our work to identify the primary challenges that our teacher advisors have encountered while teaching climate science in their classrooms. Furthermore, we are working to co-create dynamic solutions with the teachers to address these problems using the LMAC platform.

Masking with faces in central visual field under a variety of temporal schedules.

PubMed

Daar, Marwan; Wilson, Hugh R

2015-11-01

With a few exceptions, previous studies have explored masking using either a backward mask or a common onset trailing mask, but not both. In a series of experiments, we demonstrate the use of faces in central visual field as a viable method to study the relationship between these two types of mask schedule. We tested observers in a two alternative forced choice face identification task, where both target and mask comprised synthetic faces, and show that a simple model can successfully predict masking across a variety of masking schedules ranging from a backward mask to a common onset trailing mask and a number of intermediate variations. Our data are well accounted for by a window of sensitivity to mask interference that is centered at around 100 ms. Copyright © 2015 Elsevier Ltd. All rights reserved.

Challenges in healthcare delivery in an economic downturn, in the Republic of Ireland.

PubMed

Carney, Marie

2010-07-01

The purpose of the present study was to discuss some of effects of the downturn in the Irish economy and to demonstrate that in the face of economic difficulties innovation in health care is still occurring. Staff that are managing and delivering healthcare need to know the challenges facing them and have an awareness of the importance of maintaining interest in innovative practice in turbulent times. Information obtained from several sources including government papers, the nursing regulatory board and quality authority documents and current best practice articles. Information was evaluated based on the study's aim. Issues emerging were that current challenges facing Irish health care delivery relate mainly to economic, clinical management, education and information technology factors and further reductions in the cost base of health care delivery remains focused on value for money. In the face of the economic downturn Ireland is achieving health targets and is now sitting in 13th place on the European health index, down from number 28 in 2008. This improvement in position has resulted from several new innovative work practices. As a result of cost reduction measures in place nurse managers will face greater challenges than ever before in meeting the objectives of the healthcare transformation programme.

To correlate clinical manifestations with choroidal morphology in pachychoroid disorders, including central serous chorioretinopathy, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, and polypoidal choroidal vasculopathy, using en face swept-source optical coherence tomography (OCT). Patients with pachychoroid spectrum diagnoses were identified nonconsecutively through a review of charts and multimodal imaging. Each eye was categorized as uncomplicated pachychoroid, pachychoroid pigment epitheliopathy, central serous chorioretinopathy, pachychoroid neovasculopathy, or polypoidal choroidal vasculopathy. All patients included in this series then underwent bilateral swept-source OCT. Sixty-six eyes of 33 patients were included. Numbers assigned to diagnostic categories were 8 uncomplicated pachychoroid, 13 pachychoroid pigment epitheliopathy, 27 central serous chorioretinopathy, 15 pachychoroid neovasculopathy, and 3 polypoidal choroidal vasculopathy. One eye was classified as normal. Swept-source OCT choroidal thickness maps confirmed increased thickness under the areas of pachychoroid pigment epitheliopathy, central serous chorioretinopathy, type 1 NV (pachychoroid neovasculopathy), or polyps (polypoidal choroidal vasculopathy). En face swept-source OCT showed dilated outer choroidal vessels in all eyes. In several eyes with a chronic disease, focal choriocapillaris atrophy with inward displacement of deep choroidal vessels was noted. Although clinical manifestations of pachychoroid spectrum disorders vary considerably, these entities share morphologic findings in the choroid, including increased thickness and dilated outer choroidal vessels. En face swept-source OCT localizes these changes to disease foci and shows additional findings that may unify our understanding of disease pathogenesis.

The ethics of health service delivery: a challenge to public health leadership.

PubMed

DeLuca, D M

1989-01-01

The ethical distribution of health care is a central issue now that AIDS has started to be a drain on health care resources. If the worst predictions are true, the next half century will be capitalized by a great stress of the health care delivery system in the Pacific. The critical challenges that face the current leadership are: sustaining commitment to all levels of administration to reduce social and health inequities; making sound decisions on policies, priorities and goals that are based on valid information; strengthen health infrastructure, based on the principle of primary health care, including appropriate distribution of staffing, skills, technology and resources. The goals of the Pacific Health Promotion and Development center must not focus exclusively on AIDs. Hepatitis B control measures, hypertension and diabetes, primary care in remote areas, and rehabilitation initiatives must be kept in place. Humanitarian interests for AIDs patients must be balanced with the pragmatic reality of saving children's hearing, or extending useful lives. The attributes of respect, accountability, leadership, judgement, fairness, integrity and honesty controlled by principles of social justice must be part of the administrative decision making process. The 2 major issues facing public health professional are: (1) the financial considerations involved with increasingly expensive technology, services and research, contrasted against the need to prioritize their use and development; (2) pragmatic and ideological needs must be balanced to maximize preventative and curative services and make them available to those who can benefit from them.

The precautionary principle in environmental science.

Environmental scientists play a key role in society's responses to environmental problems, and many of the studies they perform are intended ultimately to affect policy. The precautionary principle, proposed as a new guideline in environmental decision making, has four central components: taking preventive action in the face of uncertainty; shifting the burden of proof to the proponents of an activity; exploring a wide range of alternatives to possibly harmful actions; and increasing public participation in decision making. In this paper we examine the implications of the precautionary principle for environmental scientists, whose work often involves studying highly complex, poorly understood systems, while at the same time facing conflicting pressures from those who seek to balance economic growth and environmental protection. In this complicated and contested terrain, it is useful to examine the methodologies of science and to consider ways that, without compromising integrity and objectivity, research can be more or less helpful to those who would act with precaution. We argue that a shift to more precautionary policies creates opportunities and challenges for scientists to think differently about the ways they conduct studies and communicate results. There is a complicated feedback relation between the discoveries of science and the setting of policy. While maintaining their objectivity and focus on understanding the world, environmental scientists should be aware of the policy uses of their work and of their social responsibility to do science that protects human health and the environment. The precautionary principle highlights this tight, challenging linkage between science and policy. PMID:11673114

Doing implementation research on health governance: a frontline researcher's reflexive account of field-level challenges and their management.

Implementation Research (IR) in and around health systems comes with unique challenges for researchers including implementation, multi-layer governance, and ethical issues. Partnerships between researchers, implementers, policy makers and community members are central to IR and come with additional challenges. In this paper, we elaborate on the challenges faced by frontline field researchers, drawing from experience with an IR study on Village Health Sanitation and Nutrition Committees (VHSNCs). The IR on VHSNC took place in one state/province in India over an 18-month research period. The IR study had twin components; intervention and in-depth research. The intervention sought to strengthen the VHSNC functioning, and concurrently the research arm sought to understand the contextual factors, pathways and mechanism affecting VHSNC functions. Frontline researchers were employed for data collection and a research assistant was living in the study sites. The frontline research assistant experienced a range of challenges, while collecting data from the study sites, which were documented as field memos and analysed using inductive content analysis approach. Due to the relational nature of IR, the challenges coalesced around two sets of relationships (a) between the community and frontline researchers and (b) between implementers and frontline researchers. In the community, the frontline researcher was viewed as the supervisor of the intervention and was perceived by the community to have power to bring about beneficial changes with public services and facilities. Implementers expected help from the frontline researcher in problem-solving in VHSNCs, and feedback on community mobilization to improve their approaches. A concerted effort was undertaken by the whole research team to clarify and dispel concerns among the community and implementers through careful and constant communication. The strategies employed were both managerial, relational and reflexive in nature. Frontline researchers through their experiences shape the research process and its outcome and they play a central role in the research. It demonstrates that frontline researcher resilience is very crucial when conducting health policy and systems research.

Thermal-to-visible face recognition using partial least squares.

PubMed

Hu, Shuowen; Choi, Jonghyun; Chan, Alex L; Schwartz, William Robson

2015-03-01

Although visible face recognition has been an active area of research for several decades, cross-modal face recognition has only been explored by the biometrics community relatively recently. Thermal-to-visible face recognition is one of the most difficult cross-modal face recognition challenges, because of the difference in phenomenology between the thermal and visible imaging modalities. We address the cross-modal recognition problem using a partial least squares (PLS) regression-based approach consisting of preprocessing, feature extraction, and PLS model building. The preprocessing and feature extraction stages are designed to reduce the modality gap between the thermal and visible facial signatures, and facilitate the subsequent one-vs-all PLS-based model building. We incorporate multi-modal information into the PLS model building stage to enhance cross-modal recognition. The performance of the proposed recognition algorithm is evaluated on three challenging datasets containing visible and thermal imagery acquired under different experimental scenarios: time-lapse, physical tasks, mental tasks, and subject-to-camera range. These scenarios represent difficult challenges relevant to real-world applications. We demonstrate that the proposed method performs robustly for the examined scenarios.

Threats to family planning services in Michigan: organizational responses to economic and political challenges.

PubMed

Dalton, Vanessa K; Jacobson, Peter D; Berson-Grand, Julie; Weisman, Carol S

2005-01-01

Title X is the only federal funding specifically for contraception and family planning services. This study identifies the threats and challenges Title X family planning organizations face in Michigan, and examines organizational responses to these challenges. We hypothesized that organizational responses to current challenges, including recent legislation, would differ between organizational types. We used a multiple case study design to examine safety net providers that received Title X funding in 2001. Cases were selected to represent economic and geographic diversity and included a mix of population densities. Key informants at each organization participated in face-to-face, semistructured interviews. Interviews collected data on current challenges, organizational planning processes, and organizational responses. All Title X organizations reported significant challenges, including rising costs, increasing need, and inadequate funding. Private organizations were more concerned about political challenges, especially recent Michigan legislation, than health departments. Organizational type was associated with the type of response. Health departments tended to close clinics or cut services, whereas private organizations recruited insured populations and increased patient fees. Based on these findings, the family planning safety net in Michigan appears to be undergoing significant change. These changes may decrease the availability of affordable family planning services in Michigan.

The organisational and human resource challenges facing primary care trusts: protocol of a multiple case study

2001-01-01

Background The study is designed to assess the organisational and human resource challenges faced by Primary Care Trusts (PCTs). Its objectives are to: specify the organisational and human resources challenges faced by PCTs in fulfilling the roles envisaged in government and local policy; examine how PCTs are addressing these challenges, in particular, to describe the organisational forms they have adopted, and the OD/HR strategies and initiatives they have planned or in place; assess how effective these structures, strategies and initiatives have been in enabling the PCTs to meet the organisational and human resources challenges they face; identify the factors, both internal to the PCT and in the wider health community, which have contributed to the success or failure of different structures, strategies and initiatives. Methods The study will be undertaken in three stages. In Stage 1 the key literature on public sector and NHS organisational development and human resources management will be reviewed, and discussions will be held with key researchers and policy makers working in this area. Stage 2 will focus on detailed case studies in six PCTs designed to examine the organisational and human resources challenges they face. Data will be collected using semi-structured interviews, group discussion, site visits, observation of key meetings and examination of local documentation. The findings from the case study PCTs will be cross checked with a Reference Group of up to 20 other PCG/Ts, and key officers working in organisational development or primary care at local, regional and national level. In Stage 3 analysis of findings from the preparatory work, the case studies and the feedback from the Reference Group will be used to identify practical lessons for PCTs, key messages for policy makers, and contributions to further theoretical development.

Parents play an important role in the successful implementation of AAC. Previous research has indicated that parents in different countries have varying perceptions about the use of AAC and face different challenges in its implementation. To date, there is limited information about the use of AAC by children in Malaysia or parents' views about its use. The aim of this study was to explore Malaysian parents' perception of AAC and their experience when supporting their children who use AAC. For this study, 12 parents of children with autism spectrum disorder and cerebral palsy were involved in semi-structured individual interviews. Qualitative content analysis was used to analyze interview data. Following analysis, three themes were identified: (a) impact of the use of AAC, (b) challenges faced, and (c) hopes and expectations. Participants reported that the use of AAC had a positive impact on their children, but that they faced challenges related to the child, the settings, and the system itself, as well as a lack of time and support. Findings from this study provide an insight for Malaysian speech therapists about the challenges faced by parents when supporting their children who use AAC, and how important it is to overcome these challenges to ensure successful implementation of AAC.

2014-03-01

The use of smartphones in Intelligent Transportation Systems is gaining popularity, yet many challenges exist in developing functional applications. Due to the dynamic nature of transportation, vehicular social applications face complexities such as developing robust sensor management, performing signal and image processing tasks, and sharing information among users. This study utilizes a multimodal sensor analysis framework which enables the analysis of sensors in multimodal aspect. It also provides plugin-based analyzing interfaces to develop sensor and image processing based applications, and connects its users via a centralized application as well as to social networks to facilitate communication and socialization. With the usage of this framework, an on-road anomaly detector is being developed and tested. The detector utilizes the sensors of a mobile device and is able to identify anomalies such as hard brake, pothole crossing, and speed bump crossing. Upon such detection, the video portion containing the anomaly is automatically extracted in order to enable further image processing analysis. The detection results are shared on a central portal application for online traffic condition monitoring.

Given the distributed nature of the Worldwide LHC Computing Grid and the way CPU resources are pledged and shared around the globe, Virtual Organizations (VOs) face the challenge of monitoring the use of these resources. For CMS and the operation of centralized workflows, the monitoring of how many production jobs are running and pending in the Glidein WMS production pools is very important. The Dashboard Site Status Board (SSB) provides a very flexible framework to collect, aggregate and visualize data. The CMS production monitoring team uses the SSB to define the metrics that have to be monitored and the alarms that have to be raised. During the integration of CMS production monitoring into the SSB, several enhancements to the core functionality of the SSB were required; They were implemented in a generic way, so that other VOs using the SSB can exploit them. Alongside these enhancements, there were a number of changes to the core of the SSB framework. This paper presents the details of the implementation and the advantages for current and future usage of the new features in SSB.

The Challenges of Pharmacy Education in Yemen

PubMed Central

2014-01-01

Pharmacy education in Yemen has faced many challenges since its introduction in the 1980s. Most Yemeni pharmacy schools, especially private ones, are experiencing difficulties in providing the right quality and quantity of clinical educational experiences. Most of these challenges are imbedded in a teaching style and curricula that have failed to respond to the needs of the community and country. The slow shift from traditional drug-dispensing to a patient-centered or focused approach in pharmacy practice requires a fundamental change in the roles and responsibilities of both policymakers and educators. The purpose of this paper is twofold: (1) to discuss the challenges facing the pharmacy education in Yemen; (2) to provided recommendations to overcome challenges. PMID:25386011

BDNF in schizophrenia, depression and corresponding animal models.

PubMed

Angelucci, F; Brenè, S; Mathé, A A

2005-04-01

Understanding the etiology and pathogenesis schizophrenia and depression is a major challenge facing psychiatry. One hypothesis is that these disorders are secondary to a malfunction of neurotrophic factors. Inappropriate neurotrophic support during brain development could lead to structural disorganisation in which neuronal networks are established in a nonoptimal manner. Inadequate neurotrophic support in adult individuals could ultimately be an underlying mechanism leading to decreased capacity of brain to adaptive changes and increased vulnerability to neurotoxic damage. Brain-derived neurotrophic factor (BDNF) is a mediator involved in neuronal survival and plasticity of dopaminergic, cholinergic, and serotonergic neurons in the central nervous system (CNS). In this review, we summarize findings regarding altered BDNF in schizophrenia and depression and animal models, as well as the effects of antipsychotic and antidepressive treatments on the expression of BDNF.

Clinician Educators (CEs) play an essential role in the education and patient care missions of academic medical centers. Despite their crucial role, academic advancement is slower for CEs than for other faculty. Increased clinical productivity demands and financial stressors at academic medical centers add to the existing challenges faced by CEs. This perspective seeks to provide a framework for junior CEs to consider with the goal of maximizing their chance of academic success. We discuss six action areas that we consider central to flourishing at academic medical centers: 1. Clarify what success means and define goals; 2. Seek mentorship and be a responsible mentee; 3. Develop a niche and engage in relevant professional development; 4. Network; 5. Transform educational activities into scholarship; and 6. Seek funding and other resources.

To describe challenges faced by low-middle income countries (LMICs) across the cancer spectrum, with specific focus on gynecologic cancers. MEDLINE was searched for research articles published in English between January 1, 2000 and February 1, 2015 which reported on global health efforts in LMICs. An estimated 80% of global cancer burden and only 5% of global cancer spending affect LMICs. The overwhelming majority of cervical cancer cases and related deaths occur in LMICs. The charge to close this cancer divide is at the center of global health efforts. Prevention is central to global health efforts to close the cancer divide. The gynecologic oncology community is well positioned to lead efforts in global health by partnering with institutions, professional societies and advocacy groups. Copyright © 2015 Elsevier Inc.

Locating object knowledge in the brain: comment on Bowers's (2009) attempt to revive the grandmother cell hypothesis.

PubMed

Plaut, David C; McClelland, James L

2010-01-01

According to Bowers, the finding that there are neurons with highly selective responses to familiar stimuli supports theories positing localist representations over approaches positing the type of distributed representations typically found in parallel distributed processing (PDP) models. However, his conclusions derive from an overly narrow view of the range of possible distributed representations and of the role that PDP models can play in exploring their properties. Although it is true that current distributed theories face challenges in accounting for both neural and behavioral data, the proposed localist account--to the extent that it is articulated at all--runs into more fundamental difficulties. Central to these difficulties is the problem of specifying the set of entities a localist unit represents.

Abnormal GABAergic function and face processing in schizophrenia: A pharmacologic-fMRI study.

PubMed

Tso, Ivy F; Fang, Yu; Phan, K Luan; Welsh, Robert C; Taylor, Stephan F

2015-10-01

The involvement of the gamma-aminobutyric acid (GABA) system in schizophrenia is suggested by postmortem studies and the common use of GABA receptor-potentiating agents in treatment. In a recent study, we used a benzodiazepine challenge to demonstrate abnormal GABAergic function during processing of negative visual stimuli in schizophrenia. This study extended this investigation by mapping GABAergic mechanisms associated with face processing and social appraisal in schizophrenia using a benzodiazepine challenge. Fourteen stable, medicated schizophrenia/schizoaffective patients (SZ) and 13 healthy controls (HC) underwent functional MRI using the blood oxygenation level-dependent (BOLD) technique while they performed the Socio-emotional Preference Task (SePT) on emotional face stimuli ("Do you like this face?"). Participants received single-blinded intravenous saline and lorazepam (LRZ) in two separate sessions separated by 1-3weeks. Both SZ and HC recruited medial prefrontal cortex/anterior cingulate during the SePT, relative to gender identification. A significant drug by group interaction was observed in the medial occipital cortex, such that SZ showed increased BOLD signal to LRZ challenge, while HC showed an expected decrease of signal; the interaction did not vary by task. The altered BOLD response to LRZ challenge in SZ was significantly correlated with increased negative affect across multiple measures. The altered response to LRZ challenge suggests that abnormal face processing and negative affect in SZ are associated with altered GABAergic function in the visual cortex, underscoring the role of impaired visual processing in socio-emotional deficits in schizophrenia.

There is an extreme health workforce shortage in Eastern, Central, and Southern Africa. Shortage of eye care workers impedes effective implementation of prevention of blindness programs. The World Health Organization has identified education, partnership, leadership, financing, and policy as intertwined interventions that are critical to resolving this crisis on the long term. The VISION 2020 LINK between the College of Ophthalmology of Eastern, Central, and Southern Africa and the Royal College of Ophthalmologists in the United Kingdom aims to increase the quantity and quality of eye care training in East, Central, and Southern Africa through a focus on five strategic areas: fellowship examination for ophthalmologists, training the trainers, curriculum development for residents in ophthalmology and ophthalmic clinical officers, continuous professional development (CPD), and mentoring program for young ophthalmologists. This study examined how education and partnership can be linked to improve eye care, through an evaluation of this north-south link based on its own targets and established frameworks to guide north-south links. An exploratory qualitative case study design was used. Twenty-nine link representatives were recruited through purposive sampling and snowballing. Face-to-face interviews were conducted using a semi-structured interview schedule that incorporated the components of a successful link from an existing framework. Documents pertaining to the link were also examined. Thematic analysis was used for data analysis. The findings revealed that the perception to the contribution of the link to eye care in the region is generally positive. Process indicators showed that the targets in three strategic objectives of the link have been achieved. Framework-based evaluation also showed that the link is successful. Mutual learning and development of friendships were the most commonly identified success factors. Inadequate awareness of the link by college members is a key challenge. The study concludes that the link is active and evolving and has achieved most of its targets. Further developments should be directed to influence health system strengthening in Eastern, Central, and Southern Africa more strategically. The study recommends expansion of the scope of collaboration to involve multiple health system building blocks.

Background U-CARE is a multidisciplinary eHealth research program that involves the disciplines of caring science, clinical psychology, health economics, information systems, and medical science. It was set up from scratch in a university setting in 2010, funded by a governmental initiative. While establishing the research program, many challenges were faced. Systematic documentation of experiences from establishing new research environments is scarce. Objective The aim of this paper was to describe the challenges of establishing a publicly funded multidisciplinary eHealth research environment. Methods Researchers involved in developing the research program U-CARE identified challenges in the formal documentation and by reflecting on their experience of developing the program. The authors discussed the content and organization of challenges into themes until consensus was reached. Results The authors identified 15 major challenges, some general to establishing a new research environment and some specific for multidisciplinary eHealth programs. The challenges were organized into 6 themes: Organization, Communication, Implementation, Legislation, Software development, and Multidisciplinarity. Conclusions Several challenges were faced during the development of the program and several accomplishments were made. By sharing our experience, we hope to help other research groups embarking on a similar journey to be prepared for some of the challenges they are likely to face on their way. PMID:28536090

Taxonomy of Challenges for Digital Forensics.

PubMed

Karie, Nickson M; Venter, Hein S

2015-07-01

Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well-defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area. © 2015 American Academy of Forensic Sciences.

Hyperspectral face recognition with spatiospectral information fusion and PLS regression.

PubMed

Uzair, Muhammad; Mahmood, Arif; Mian, Ajmal

2015-03-01

Hyperspectral imaging offers new opportunities for face recognition via improved discrimination along the spectral dimension. However, it poses new challenges, including low signal-to-noise ratio, interband misalignment, and high data dimensionality. Due to these challenges, the literature on hyperspectral face recognition is not only sparse but is limited to ad hoc dimensionality reduction techniques and lacks comprehensive evaluation. We propose a hyperspectral face recognition algorithm using a spatiospectral covariance for band fusion and partial least square regression for classification. Moreover, we extend 13 existing face recognition techniques, for the first time, to perform hyperspectral face recognition.We formulate hyperspectral face recognition as an image-set classification problem and evaluate the performance of seven state-of-the-art image-set classification techniques. We also test six state-of-the-art grayscale and RGB (color) face recognition algorithms after applying fusion techniques on hyperspectral images. Comparison with the 13 extended and five existing hyperspectral face recognition techniques on three standard data sets show that the proposed algorithm outperforms all by a significant margin. Finally, we perform band selection experiments to find the most discriminative bands in the visible and near infrared response spectrum.

Aptel, Florent; Attye, Arnaud; Guyader, Nathalie; Boucart, Muriel; Chiquet, Christophe; Peyrin, Carole

2018-01-01

Primary open-angle glaucoma (POAG) firstly mainly affects peripheral vision. Current behavioral studies support the idea that visual defects of patients with POAG extend into parts of the central visual field classified as normal by static automated perimetry analysis. This is particularly true for visual tasks involving processes of a higher level than mere detection. The purpose of this study was to assess visual abilities of POAG patients in central vision. Patients were assigned to two groups following a visual field examination (Humphrey 24–2 SITA-Standard test). Patients with both peripheral and central defects and patients with peripheral but no central defect, as well as age-matched controls, participated in the experiment. All participants had to perform two visual tasks where low-contrast stimuli were presented in the central 6° of the visual field. A categorization task of scene images and human face images assessed high-level visual recognition abilities. In contrast, a detection task using the same stimuli assessed low-level visual function. The difference in performance between detection and categorization revealed the cost of high-level visual processing. Compared to controls, patients with a central visual defect showed a deficit in both detection and categorization of all low-contrast images. This is consistent with the abnormal retinal sensitivity as assessed by perimetry. However, the deficit was greater for categorization than detection. Patients without a central defect showed similar performances to the controls concerning the detection and categorization of faces. However, while the detection of scene images was well-maintained, these patients showed a deficit in their categorization. This suggests that the simple loss of peripheral vision could be detrimental to scene recognition, even when the information is displayed in central vision. This study revealed subtle defects in the central visual field of POAG patients that cannot be predicted by static automated perimetry assessment using Humphrey 24–2 SITA-Standard test.

Partelow, Stefan; von Wehrden, Henrik; Horn, Olga

2015-11-15

Marine protected areas (MPAs) face many challenges in their aim to effectively conserve marine ecosystems. In this study we analyze the extent of pollution exposure on the global fleet of MPAs. This includes indicators for current and future pollution and the implications for regionally clustered groups of MPAs with similar biophysical characteristics. To cluster MPAs into characteristic signature groups, their bathymetry, baseline biodiversity, distance from shore, mean sea surface temperature and mean sea surface salinity were used. We assess the extent at which each signature group is facing exposure from multiple pollution types. MPA groups experience similar pollution exposure on a regional level. We highlight how the challenges that MPAs face can be addressed through governance at the appropriate scale and design considerations for integrated terrestrial and marine management approaches within regional level networks. Furthermore, we present diagnostic social-ecological indicators for addressing the challenges facing unsuccessful MPAs with practical applications. Copyright © 2015 Elsevier Ltd.

Successes, challenges and needs regarding rural health medical education in continental Central America: a literature review and narrative synthesis.

PubMed

Colon-Gonzalez, Maria C; El Rayess, Fadya; Guevara, Sara; Anandarajah, Gowri

2015-01-01

Central American countries, like many others, face a shortage of rural health physicians. Most medical schools in this region are located in urban areas and focus on tertiary care training rather than on community health or primary care, which are better suited for rural practice. However, many countries require young physicians to do community service in rural communities to address healthcare provider shortages. This study aimed to: (a) synthesize what is known about the current state of medical education preparing physicians for rural practice in this region, and (b) identify common needs, challenges and opportunities for improving medical education in this area. A comprehensive literature review was conducted between December 2013 and May 2014. The stepwise, reproducible search process included English and Spanish language resources from both data-based web search engines (PubMed, Web of Science/Web of Knowledge, ERIC and Google Scholar) and the grey literature. Search criteria included MeSH terms: 'medical education', 'rural health', 'primary care', 'community medicine', 'social service', in conjunction with 'Central America', 'Latin America', 'Mexico', 'Guatemala', 'Belize', 'El Salvador', 'Nicaragua', 'Honduras', 'Costa Rica' and 'Panama'. Articles were included in the review if they (1) were published after 1984; (2) focused on medical education for rural health, primary care, community health; and (3) involved the countries of interest. A narrative synthesis of the content of resources meeting inclusion criteria was done using qualitative research methods to identify common themes pertaining to the study goals. The search revealed 20 resources that met inclusion criteria. Only four of the 20 were research articles; therefore, information about this subject was primarily derived from expert opinion. Thematic analysis revealed the historical existence of several innovative programs that directly address rural medicine training needs, suggesting that expertise is present in this region. However, numerous challenges limit sustainability or expansion of successful programs. Common challenges include: (a) physicians' exposure to rural medicine primarily takes place during social service commitment time, rather than during formal medical training; (b) innovative educational programs are often not sustainable due to financial and leadership challenges; (c) the majority of physician manpower is in urban areas, resulting in few rural physician role models and teachers; and (d) there is insufficient collaboration to establish clinical and educational systems to meet rural health needs. Recurring suggestions for curricular changes include: (a) making primary care training a core component of medical school education; and (b) expanding medical school curricula in cross-cultural communication and social determinants of disease. Suggestions for health system changes include: (a) improving living and working conditions for rural physicians; and (b) establishing partnerships between educational, governmental and non-governmental organizations and rural community leadership, to promote rural health training and systems. Expertise in rural medicine and training exists in continental Central America. However, there are numerous challenges to improving medical education to meet the needs of rural communities. Overcoming these challenges will require creative solutions, new partnerships, and evaluation and dissemination of successful educational programs. There is a great need for further research on this topic.

The objective of the study is to use social network analysis to examine the acceptability of a youth-led, hybrid face-to-face and online social networking HIV prevention program for homeless youth.Seven peer leaders (PLs) engaged face-to-face homeless youth (F2F) in the creation of digital media projects (e.g. You Tube videos). PL and F2F recruited online youth (OY) to participate in MySpace and Facebook communities where digital media was disseminated and discussed. The resulting social networks were assessed with respect to size, growth, density, relative centrality of positions and homophily of ties. Seven PL, 53 F2F and 103 OY created two large networks. After the first 50 F2F youth participated, online networks entered a rapid growth phase. OY were among the most central youth in these networks. Younger aged persons and females were disproportionately connected to like youth. The program appears highly acceptable to homeless youth. Social network analysis revealed which PL were the most critical to the program and which types of participants (younger youth and females) may require additional outreach efforts in the future.

Science education in urban settings: Seeking new ways of praxis through critical ethnography

NASA Astrophysics Data System (ADS)

Calabrese Barton, Angela

2001-10-01

The challenges faced in urban science education are deeply rooted in the ongoing struggle for racial, class and gender equity. Part of this struggle is tied to huge differences in class and involves making more equitable the distribution of resources. Another part of this struggle is tied to the rich diversity of children who attend urban schools and involves generating new ways of understanding, valuing, and genuinely incorporating into school-based practices the culture, language, beliefs, and experiences that these children bring to school. Thus, this article argues that to address these two challenges - and indeed to achieve a more just science education for all urban students - explicitly political research methodologies must be considered and incorporated into urban education. One potential route for this is critical ethnography, for this kind of methodology emerges collaboratively from the lives of the researcher and the researched and is centrally about praxis and a political commitment to the struggle for liberation and in defense of human rights. In making this argument, I have drawn from stories from my own research with homeless children.

Labor-Force Participation, Policies & Practices in an Aging America: Adaptation Essential for a Healthy & Resilient Population

Berkman, Lisa F.; Börsch-Supan, Axel; Avendano, Mauricio

2016-01-01

Population aging in the United States poses challenges to societal institutions while simultaneously creating opportunities to build a more resilient, successful, and cohesive society. Work organization and labor-force participation are central to both the opportunities and challenges posed by our aging society. We argue that expectations about old age have not sufficiently adapted to the reality of aging today. Our institutions need more adaptation in order to successfully face the consequences of demographic change. Although this adaptation needs to focus especially on work patterns among the “younger elderly,” our society has to change its general attitudes toward work organization and labor-force participation, which will have implications for education and health care. We also show that work’s beneficial effects on well-being in older ages are often neglected, while the idea that older workers displace younger workers is a misconception emerging from the “lump of labor” fallacy. We conclude, therefore, that working at older ages can lead to better quality of life for older people and to a more productive and resilient society overall. PMID:28042166

Is the "flipped" pedagogical model the answer to the challenges of rural nursing education?: A discussion paper?

PubMed

Anolak, Helena; Coleman, Andrew; Sugden, Paul

2018-07-01

Rural Australian health services face significant challenges such as aging populations, access and retention of services and health practitioners as well as difficulties with staff training due to geographic isolation. Educational pedagogy, through a 'flipped' or 'flipped' classroom method has become popular in nursing literature whereby discussion surrounding its effectiveness, ability to increase performance, address learning outcomes and resolve the education-clinical practice divide is currently being explored. Several reviews that look specifically at the validity and implementation of the flipped classroom pedagogy into nursing education demonstrate a need for further scientific research. Current literature examines the in-class on campus implementation of the methodology but rarely does it consider the advantages or ways of implementing such a method in a rural off campus nursing learning environment. The use of technology is not the solution unless supported by interaction to develop practical situational skills. The authors consider advantages and disadvantages and identify central problems for the effective implementation of 'flipped' in off-campus rural nursing education. Copyright © 2018 Elsevier Ltd.

Systems biology aims to integrate multiple biological data types such as genomics, transcriptomics and proteomics across different levels of structure and scale; it represents an emerging paradigm in the scientific process which challenges the reductionism that has dominated biomedical research for hundreds of years. Systems biology will nevertheless only be successful if the technologies on which it is based are able to deliver the required type and quality of data. In this review we discuss how well positioned is proteomics to deliver the data necessary to support meaningful systems modelling in parasite biology. We summarise the current state of identification proteomics in parasites, but argue that a new generation of quantitative proteomics data is now needed to underpin effective systems modelling. We discuss the challenges faced to acquire more complete knowledge of protein post-translational modifications, protein turnover and protein-protein interactions in parasites. Finally we highlight the central role of proteome-informatics in ensuring that proteomics data is readily accessible to the user-community and can be translated and integrated with other relevant data types.

The importance of living botanical collections for plant biology and the “next generation” of evo-devo research

Dosmann, Michael; Groover, Andrew

2012-01-01

Living botanical collections include germplasm repositories, long-term experimental plantings, and botanical gardens. We present here a series of vignettes to illustrate the central role that living collections have played in plant biology research, including evo-devo research. Looking toward the future, living collections will become increasingly important in support of future evo-devo research. The driving force behind this trend is nucleic acid sequencing technologies, which are rapidly becoming more powerful and cost-effective, and which can be applied to virtually any species. This allows for more extensive sampling, including non-model organisms with unique biological features and plants from diverse phylogenetic positions. Importantly, a major challenge for sequencing-based evo-devo research is to identify, access, and propagate appropriate plant materials. We use a vignette of the ongoing 1,000 Transcriptomes project as an example of the challenges faced by such projects. We conclude by identifying some of the pinch points likely to be encountered by future evo-devo researchers, and how living collections can help address them. PMID:22737158

Challenges faced by China compared with the US in developing wind power

2016-06-01

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.

Perceptual and Gaze Biases during Face Processing: Related or Not?

Samson, Hélène; Fiori-Duharcourt, Nicole; Doré-Mazars, Karine; Lemoine, Christelle; Vergilino-Perez, Dorine

2014-01-01

Previous studies have demonstrated a left perceptual bias while looking at faces, due to the fact that observers mainly use information from the left side of a face (from the observer's point of view) to perform a judgment task. Such a bias is consistent with the right hemisphere dominance for face processing and has sometimes been linked to a left gaze bias, i.e. more and/or longer fixations on the left side of the face. Here, we recorded eye-movements, in two different experiments during a gender judgment task, using normal and chimeric faces which were presented above, below, right or left to the central fixation point or on it (central position). Participants performed the judgment task by remaining fixated on the fixation point or after executing several saccades (up to three). A left perceptual bias was not systematically found as it depended on the number of allowed saccades and face position. Moreover, the gaze bias clearly depended on the face position as the initial fixation was guided by face position and landed on the closest half-face, toward the center of gravity of the face. The analysis of the subsequent fixations revealed that observers move their eyes from one side to the other. More importantly, no apparent link between gaze and perceptual biases was found here. This implies that we do not look necessarily toward the side of the face that we use to make a gender judgment task. Despite the fact that these results may be limited by the absence of perceptual and gaze biases in some conditions, we emphasized the inter-individual differences observed in terms of perceptual bias, hinting at the importance of performing individual analysis and drawing attention to the influence of the method used to study this bias.

When children have special health care needs, parents assume the roles of care coordinator, medical expert, and systems advocate as well as their typical parenting roles. They face many challenges in managing their child's chronic condition in the context of everyday life. Health care providers are uniquely positioned to assist parents in meeting those challenges and to promote parent competency and confidence in their child's care. The data for this analysis were collected during classes for parents of children with chronic conditions who took part in a randomized controlled study of a curriculum's effectiveness. During facilitated discussions, parents discussed challenges they faced and generated strategies they found helpful. Qualitative data analysis revealed dominant themes across subject areas. Challenges included social isolation, strained relationships and ongoing frustrations with health care and educational systems. Helpful strategies focused on being prepared, connecting with peers, becoming an advocate, developing partnerships and caring for one's self. Implications for health care providers include: understanding common challenges parents face; promoting parent-to-parent connections; and building partnerships with parents and their children with special needs.

Enhanced facial texture illumination normalization for face recognition.

PubMed

Luo, Yong; Guan, Ye-Peng

2015-08-01

An uncontrolled lighting condition is one of the most critical challenges for practical face recognition applications. An enhanced facial texture illumination normalization method is put forward to resolve this challenge. An adaptive relighting algorithm is developed to improve the brightness uniformity of face images. Facial texture is extracted by using an illumination estimation difference algorithm. An anisotropic histogram-stretching algorithm is proposed to minimize the intraclass distance of facial skin and maximize the dynamic range of facial texture distribution. Compared with the existing methods, the proposed method can more effectively eliminate the redundant information of facial skin and illumination. Extensive experiments show that the proposed method has superior performance in normalizing illumination variation and enhancing facial texture features for illumination-insensitive face recognition.

Ranking fluctuating asymmetry in a dot figure and the significant impact of imagining a face.

PubMed

Neby, Magne; Ivar, Folstad

2013-01-01

Fluctuating asymmetry and averageness is correlated with our perception of beauty in human faces. Yet, whether deviations of centrality in the positioning of the eyes, the nose, and the mouth have different effects on our perception of asymmetry in a holistic human face, is still uncertain. In this study we aimed to test the relative effect of decentralising the horizontal position of three sets of paired dots representing eyes, nostrils, or mouth from the vertical midline of ambiguous dot figures, vaguely resembling a face. The figures were ranked according to perceived asymmetry by human observers. When associating the figures with non-facial objects (eg a butterfly), none of the figures' rank distribution differed from each other. However, when observers imagined the figures to represent a human face, the figure with the decentralised pair of dots representing the nostrils was significantly ranked as more asymmetric than the other figures. This result provides indications that the brain may deal with information about facial asymmetry and averageness heavily depending on the centrality of the nasal region.

One of the grand challenges currently facing engineering, life sciences, and medicine is the development of fully functional nanorobots capable of sensing, decision making, and actuation. These nanorobots may aid in cancer therapy, site-specific drug delivery, circulating diagnostics, advanced surgery, and tissue repair. In this paper, we will discuss, from a bioinspired perspective, the challenges currently facing nanorobotics, including core design, propulsion and power generation, sensing, actuation, control, decision making, and system integration. Using strategies inspired from microorganisms, we will discuss a potential bioengineered nanorobot for cancer therapy.

Scientists and entrepreneurs who contemplate developing nanomedicine products face several unique challenges in addition to many of the traditional hurdles of product development. In this review we analyze the major physicochemical, biologic and functional characteristics of several nanomedicine products on the market and explore the question of what made them unique. What made them successful? We also focus on the regulatory challenges faced by nanomedicine product developers. Based on these analyses, we propose the factors that are most likely to contribute to the success of nanomedicine products.

Lee, Dong-Su; Woo, Yong-Hyun; Yeom, Seokwon; Kim, Shin-Hwan

2012-06-01

Face identification at a distance is very challenging since captured images are often degraded by blur and noise. Furthermore, the computational resources and memory are often limited in the mobile environments. Thus, it is very challenging to develop a real-time face identification system on the mobile device. This paper discusses face identification based on frequency domain matched filtering in the mobile environments. Face identification is performed by the linear or phase-only matched filter and sequential verification stages. The candidate window regions are decided by the major peaks of the linear or phase-only matched filtering outputs. The sequential stages comprise a skin-color test and an edge mask filtering test, which verify color and shape information of the candidate regions in order to remove false alarms. All algorithms are built on the mobile device using Android platform. The preliminary results show that face identification of East Asian people can be performed successfully in the mobile environments.

Chronic Disease and Depression Among Hispanic Americans: Reconceptualizing the Masculine Self.

PubMed

Chan, Isabella; Corvin, Jaime A

2016-11-01

Hispanic Americans are the fastest growing minority group in the United States. They face a distinct set of health challenges, resulting in persistent health disparities. Chronic disease self-management programs hold promise in addressing individual-level, behavioral risks factors, such as dietary habits and physical activity patterns. In light of the unique barriers Hispanic men face, including low participation in evidence-based health intervention research, this article argues for a gendered perspective when approaching Hispanic men's physical and mental health needs. Through the analysis of data collected from male-only focus groups (N = 3, n = 15) with Hispanic Americans in west central Florida, this study identified that masculine identity is influenced by chronic disease and comorbid depression status. Diagnosis with a chronic disease and/or depression is accompanied by lifestyle adaptations, activity restrictions, and changes in income and health care demands that can undermine traditional notions of Hispanic masculinity. Consequently, masculine identity is associated with self-management strategies in complex ways. Public health interventions aimed at addressing comorbid chronic disease and depression among Hispanic men must take into consideration the role of gender identity and relevant conceptualizations of masculinity in order to better serve this underserved and understudied population. © The Author(s) 2015.

Scott, Veronica M; Mottarella, Karen E; Lavooy, Maria J

2006-12-01

This study examined the levels of intimacy reported by individuals in face-to-face and computer-mediated (or "virtual") romantic relationships. As suggested by the media and promised by online dating services, some degree of intimacy was reported in computer-mediated relationships, but stronger intimacy was reported in all participants' face-to-face relationships. Results also indicated that individuals who had online, virtual relationships reported less intimacy in their own face-to-face relationships compared to individuals who had engaged exclusively in face-to-face relationships, suggesting that people may turn to virtual relating after challenges in their face-to-face experiences.

The study reported in this article had three objectives: 1) identify the challenges faced by authors of dental systematic reviews (SR) during the process of literature search and selection; 2) determine whether dental SR authors' responses to survey questions about their study methodology were consistent with the reported published methodology; and 3) assess whether dental SR authors' evidence-based publication experience was associated with reported methodology. Seventy-eight authors (53 percent) of dental SRs out of 147 potential authors published from 2000 to 2006 responded to an online survey. According to the respondents, the most challenging aspects of literature search and selection were the initial design and performing extended literature searches. Agreement between the protocol identified by SR authors on the survey and the actual protocol described in their publications was fair to moderate. There were virtually no correlations between authors' publication experience, systematic review literature search, and selection thoroughness except for the number of past SRs published, and no differences in thoroughness between SRs written by clinicians (dental practitioners in the community) and dental school faculty members. Dental SR authors do not appear to fully appreciate the importance of extensive literature searches as central to the validity of their systematic review methods and potential findings.

Modeling and replicating statistical topology and evidence for CMB nonhomogeneity

PubMed Central

Agami, Sarit

2017-01-01

Under the banner of “big data,” the detection and classification of structure in extremely large, high-dimensional, data sets are two of the central statistical challenges of our times. Among the most intriguing new approaches to this challenge is “TDA,” or “topological data analysis,” one of the primary aims of which is providing nonmetric, but topologically informative, preanalyses of data which make later, more quantitative, analyses feasible. While TDA rests on strong mathematical foundations from topology, in applications, it has faced challenges due to difficulties in handling issues of statistical reliability and robustness, often leading to an inability to make scientific claims with verifiable levels of statistical confidence. We propose a methodology for the parametric representation, estimation, and replication of persistence diagrams, the main diagnostic tool of TDA. The power of the methodology lies in the fact that even if only one persistence diagram is available for analysis—the typical case for big data applications—the replications permit conventional statistical hypothesis testing. The methodology is conceptually simple and computationally practical, and provides a broadly effective statistical framework for persistence diagram TDA analysis. We demonstrate the basic ideas on a toy example, and the power of the parametric approach to TDA modeling in an analysis of cosmic microwave background (CMB) nonhomogeneity. PMID:29078301

Education as an intergenerational process of human learning, teaching, and development.

PubMed

Cole, Michael

2010-11-01

In this article I argue that the future of psychological research on educational processes would benefit from an interdisciplinary approach that enables psychologists to locate their objects of study within the cultural, social, and historical contexts of their research. To make this argument, I begin by examining anthropological accounts of the characteristics of education in small, face-to-face, preindustrial societies. I then turn to a sample of contemporary psychoeducational research that seeks to implement major, qualitative changes in modern educational practices by transforming them to have the properties of education in those self-same face-to-face societies. Next I examine the challenges faced by these modern approaches and briefly describe a multi-institutional, multidisciplinary system of education that responds to these challenges while offering a model for educating psychology students in a multigenerational system of activities with potential widespread benefits.

Industrial Development and Challenges of Water Pollution in Coastal Areas: The Case of Surat, India

NASA Astrophysics Data System (ADS)

Bansal, Neeru

2018-03-01

Industrialisation plays an important role in the economic development of a country, however, pollution is the inevitable price paid for this development. Surat, a major industrial hub in western India, is located on the bank of the river Tapi and extends up to the Arabian Sea. The city is characterised by the presence of a number of creeks (known as ‘khadis’ in local language). This paper focusses on the industrial development in Surat and the challenges faced by the city due to water pollution. A constant deterioration in the quality of surface water resources has been observed due to discharge of treated or partially treated effluents from the industries. The problem of water pollution becomes critical due to increase in frequency of flooding, risks faced by the city due to climate change and the ineffective environmental governance. The paper provides insights into the challenges faced by the city and the learnings can lead to adoption of policy initiatives and other measures which can effectively address these challenges.

USGS Science: Addressing Our Nation's Challenges

USGS Publications Warehouse

Larson, Tania M.

2009-01-01

With 6.6 billion people already living on Earth, and that number increasing every day, human influence on our planet is ever more apparent. Changes to the natural world combined with increasing human demands threaten our health and safety, our national security, our economy, and our quality of life. As a planet and a Nation, we face unprecedented challenges: loss of critical and unique ecosystems, the effects of climate change, increasing demand for limited energy and mineral resources, increasing vulnerability to natural hazards, the effects of emerging diseases on wildlife and human health, and growing needs for clean water. The time to respond to these challenges is now, but policymakers and decisionmakers face difficult choices. With competing priorities to balance, and potentially serious - perhaps irreversible - consequences at stake, our leaders need reliable scientific information to guide their decisions. As the Nation's earth and natural science agency, the USGS monitors and conducts scientific research on natural hazards and resources and how these elements and human activities influence our environment. Because the challenges we face are complex, the science needed to better understand and deal with these challenges must reflect the complex interplay among natural and human systems. With world-class expertise in biology, geology, geography, hydrology, geospatial information, and remote sensing, the USGS is uniquely capable of conducting the comprehensive scientific research needed to better understand the interdependent interactions of Earth's systems. Every day, the USGS helps decisionmakers to minimize loss of life and property, manage our natural resources, and protect and enhance our quality of life. This brochure provides examples of the challenges we face and how USGS science helps decisionmakers to address these challenges.

2012-01-01

Introduction In 2003, an ICRC-SFD Ponseti program was introduced in southern Vietnam. Additional programs were introduced by the Prosthetics Outreach Foundation and independently by physicians trained at our center. The purpose of this study was to evaluate the impact, progress and challenges facing Ponseti practitioners and patients' family members in Vietnam. In addition, web-conferencing (Ponseti Virtual Forum) for continued medical education in the method was also assessed. Methods Multiple questionnaires were developed to conduct face-to-face practitioner interviews, focus group interviews, and parental interviews. Observation was done at multiple site clinics to determine or confirm additional challenges faced by practitioners. Web conferencing was introduced to sites in Ho Chi Minh City and Da Nang City. Results The number of clubfoot patients treated with the Ponseti method has increased over time with approximately 1,252 infants treated between 2003 and 2010. Specific challenges were identified relating to communication, networking, distance and transportation, and finances for both practitioners and parents. The PVF was not only found to facilitate rapid, relevant dissemination of medical knowledge – thus increasing physician and patient satisfaction – but it may also be found to act as an interface in which medical culture, insight, and compassion are shared benefiting all virtual forum participants. Conclusion The identified progress and challenges mirrored that of similar studies done in other countries with several factors affecting progress. Focusing on improving communication channels and networking while working with the ministry of health may improve the facilitation of the Ponseti method in Vietnam. Further implementation and evaluation of the PVF may act as a guide for current and future programs in Vietnam or other countries. PMID:23576933

Recommendations on Arresting Global Health Challenges Facing Adolescents and Young Adults.

PubMed

Lassi, Zohra S; Salam, Rehana A; Bhutta, Zulfiqar A

The health challenges faced by young people are more complex than adults and can compromise their full growth and development. Attention must be paid to the health of this age group, yet adolescents and youth remain largely invisible and often disappear from the major global datasets. The aim of this paper is to discuss the global health challenges faced by adolescents and youth, global legislations and guidelines pertaining to this particular age group, recommendations to arrest these challenges, and research priorities. Major direct and indirect global health risks faced by adolescents include early pregnancy and childbirth, femicide, honor killing, female genital mutilation, nutritional habits and choices, social media, and peer pressure. There are no standard legal age cut-offs for adulthood; rather, the age varies for different activities, such as age of consent or the minimum age that young people can legally work, leave school, drive, buy alcohol, marry, be held accountable for criminal action, and make medical decisions. This reflects the fact that the existing systems and structures are focused on either children or adults, with very few investments and interventions directed specifically to young people. Existing legislation and guidelines need transformation to bring about a specific focus on adolescents in the domains of substance use and sexual behaviors, and the capacity for adolescent learning should be exploited through graduated legal and policy frameworks. Sustainable development goals provide an opportunity to target this neglected and vulnerable age group. A multisectoral approach is needed to bring about healthy change and address the challenges faced by adolescents and youth, from modifications at a broader legislative and policy level to ground-level (community-level) implementations.

Ooi, Khim Lynn; Ong, Yin Sin; Jacob, Sabrina Anne; Khan, Tahir Mehmood

2016-01-01

Background The lifelong nature of autism in a child has deep implications on parents as they are faced with a range of challenges and emotional consequences in raising the child. The aim of this meta-synthesis was to explore the perspectives of parents in raising a child with autism in the childhood period to gain an insight of the adaptations and beliefs of parents toward autism, their family and social experiences, as well as their perceptions toward health and educational services. Methods A systematic search of six databases (PubMed, EMBASE, PsychInfo, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Database of Abstracts of Reviews of Effects [DARE]) was conducted from inception up to September 30, 2014. Full-text English articles of qualitative studies describing parents’ perceptions relating to the care of children younger than 12 years of age and diagnosed with a sole disorder of autism were included. Results A total of 50 eligible articles were appraised and analyzed, identifying four core themes encompassing all thoughts, emotions, and experiences commonly expressed by parents: 1) The Parent, 2) Impact on the Family, 3) Social Impact, and 4) Health and Educational Services. Findings revealed that parents who have a child with autism experienced multiple challenges in different aspects of care, impacting on parents’ stress and adaptation. Conclusion Health care provision should be family centered, addressing and supporting the needs of the whole family and not just the affected child, to ensure the family’s well-being and quality of life in the face of a diagnosis of autism.

Comparative psychology and the grand challenge of drug discovery in psychiatry and neurodegeneration.

PubMed

Brunner, Dani; Balcı, Fuat; Ludvig, Elliot A

2012-02-01

Drug discovery for brain disorders is undergoing a period of upheaval. Faced with an empty drug pipeline and numerous failures of potential new drugs in clinical trials, many large pharmaceutical companies have been shrinking or even closing down their research divisions that focus on central nervous system (CNS) disorders. In this paper, we argue that many of the difficulties facing CNS drug discovery stem from a lack of robustness in pre-clinical (i.e., non-human animal) testing. There are two main sources for this lack of robustness. First, there is the lack of replicability of many results from the pre-clinical stage, which we argue is driven by a combination of publication bias and inappropriate selection of statistical and experimental designs. Second, there is the frequent failure to translate results in non-human animals to parallel results in humans in the clinic. This limitation can only be overcome by developing new behavioral tests for non-human animals that have predictive, construct, and etiological validity. Here, we present these translational difficulties as a "grand challenge" to researchers from comparative cognition, who are well positioned to provide new methods for testing behavior and cognition in non-human animals. These new experimental protocols will need to be both statistically robust and target behavioral and cognitive processes that allow for better connection with human CNS disorders. Our hope is that this downturn in industrial research may represent an opportunity to develop new protocols that will re-kindle the search for more effective and safer drugs for CNS disorders.

Dissemination and Exploitation: Project Goals beyond Science

NASA Astrophysics Data System (ADS)

Hamann, Kristin; Reitz, Anja

2017-04-01

Dissemination and Exploitation are essential parts of public funded projects. In Horizon 2020 a plan for the exploitation and dissemination of results (PEDR) is a requirement. The plan should contain a clear vision on the objectives of the project in relation to actions for dissemination and potential exploitation of the project results. The actions follow the basic idea to spread the knowledge and results gathered within the project and face the challenge of how to bring the results into potentially relevant policy circle and how they impact the market. The plan follows the purpose to assess the impact of the project and to address various target groups who are interested in the project results. Simply put, dissemination concentrates on the transfer of knowledge and exploitation on the commercialization of the project. Beyond the question of the measurability of project`s impact, strategies within science marketing can serve purposes beyond internal and external communication. Accordingly, project managers are facing the challenge to implement a dissemination and exploitation strategy that ideally supports the identification of all partners with the project and matches the current discourse of the project`s content within the society, politics and economy. A consolidated plan might unite all projects partners under a central idea and supports the identification with the project beyond the individual research questions. Which applications, strategies and methods can be used to bring forward a PEDR that accompanies a project successfully and allows a comprehensive assessment of the project afterwards? Which hurdles might project managers experience in the dissemination process and which tasks should be fulfilled by the project manager?

At a Crossroads: Family Medicine Education in China.

PubMed

Wu, Dan; Lam, Tai Pong

2017-02-01

China is engaged in efforts to train 300,000 family doctors by 2020 to meet its population's health care needs. This Article discusses the family doctor shortage, compares family medicine training programs, examines the distributional challenges faced by these programs, and proposes directions for further experimentation. Despite an increasing number of family doctors, they represented only 5.6% of all doctors in 2013. Currently, three training programs run concurrently-the post-transfer training, residency training, and designated family medicine undergraduate education programs. These programs face several challenges. First, the educational qualifications of primary care practitioners (PCPs) vary greatly between rural and urban regions. From 2005 to 2013, the percentage of PCPs with three or more years of medical training in urban areas was at least 20.0% higher than in rural areas. Second, regional disparities in the number of family doctors for every 10,000 people exist. The richer eastern part of China has a ratio of 1.51 family doctors for every 10,000 people, nearly double that of central (0.70) and western China (0.86). Third, better-educated doctors are most likely going to prefer to work in hospitals, which offer a lucrative career path with higher pay and social status. Intervention packages that combine student selection policies that look at place of origin and career intent with other incentive strategies are worth implementing. Adequate clinical exposure and regular, rigorous evaluations are crucial for enhancing training quality. China should strike a balance in the distribution of family doctors between the richer and poorer areas to ensure equity.

This article describes and discusses the challenges faced by researchers who conducted a qualitative interview study on attitudes toward suicide among the Baganda, Uganda. Many of the challenges addressed in this article have not been described earlier in suicide research conducted in the developing world. The aim of this study was to explore attitudes and cultural responses toward suicide among the Baganda, Uganda. Data were collected and analyzed using grounded theory. A total of 28 focus group discussions and 30 key informant interviews were conducted. The findings of this study are organized under two broad categories: community access challenges and expectation challenges. Community access challenges entailed cultural, legal, rapport, informed consent, language, and other research process related issues that could hinder effective access to the study respondents. Expectation challenges concerned how to deal with the immediate and strategic needs of the study communities. This study demonstrates that culturally sensitive approaches to data collection can reduce ethical challenges and, through innovative approaches, practical challenges faced during data collection can be minimized.

Common Challenges Faced by Women of Color in Physics, and Actions Faculty Can Take to Minimize Those Challenges

NASA Astrophysics Data System (ADS)

Johnson, Angela; Ong, Maria; Ko, Lily T.; Smith, Janet; Hodari, Apriel

2017-09-01

Women of color are deeply underrepresented in physics. Between 2002 and 2012, only 1% of graduating physics majors were Black women and another 1% were Latinas; only 61 American Indian women total completed degrees in physics in those years (out of 48,000 physics majors). This isolation can lead to additional obstacles that women of color majoring in physics must face above and beyond the challenging material. In this article we draw on qualitative findings to describe common obstacles women of color face. However, departments can take deliberate steps so that underrepresentation need not turn into loneliness and isolation. We describe the characteristics of a department where women of color report that they are thriving. We end with concrete steps physics faculty can take to support women physics majors of color.

Not-for-profit hospitals fight tax-exempt challenges.

Hudson, T

1990-10-20

The message being sent by local tax boards, state agencies, and the Internal Revenue Service is clear: Not-for-profit hospitals will have to justify their tax-exempt status. But complying with this demand can be a costly administrative burden. Just ask the executives who have been through the experience. CEO Richard Anderson, of St. Luke's Hospital, Bethlehem, PA, is luckier than some executives who have faced tax-exempt challenges. He won his hospital's case. But he still faces a yearly battle: The hospital must prove its compliance annually to the county board of assessors. Other executives report similar experiences. Our cover story takes an in-depth look at how administrators faced challenges to their hospital's tax status and what they learned about their relationship with their communities, as well as a complete state and federal legislative outlook for future developments.

While global programs targeting the control or elimination of five of the neglected tropical diseases (NTDs)-lymphatic filariasis, onchocerciasis, soil-transmitted helminthiasis, schistosomiasis and trachoma-are well underway, they still face many operational challenges. Because of the urgency of 2020 program targets, the Bill & Melinda Gates Foundation and the U.S. Agency for International Development devised a novel rapid research response (RRR) framework to engage national programs, researchers, implementers and WHO in a Coalition for Operational Research on NTDs. After 2 years, this effort has succeeded as an important basis for the research response to programmatic challenges facing NTD programs. © The Author 2016.

Tracking and recognition face in videos with incremental local sparse representation model

NASA Astrophysics Data System (ADS)

Wang, Chao; Wang, Yunhong; Zhang, Zhaoxiang

2013-10-01

This paper addresses the problem of tracking and recognizing faces via incremental local sparse representation. First a robust face tracking algorithm is proposed via employing local sparse appearance and covariance pooling method. In the following face recognition stage, with the employment of a novel template update strategy, which combines incremental subspace learning, our recognition algorithm adapts the template to appearance changes and reduces the influence of occlusion and illumination variation. This leads to a robust video-based face tracking and recognition with desirable performance. In the experiments, we test the quality of face recognition in real-world noisy videos on YouTube database, which includes 47 celebrities. Our proposed method produces a high face recognition rate at 95% of all videos. The proposed face tracking and recognition algorithms are also tested on a set of noisy videos under heavy occlusion and illumination variation. The tracking results on challenging benchmark videos demonstrate that the proposed tracking algorithm performs favorably against several state-of-the-art methods. In the case of the challenging dataset in which faces undergo occlusion and illumination variation, and tracking and recognition experiments under significant pose variation on the University of California, San Diego (Honda/UCSD) database, our proposed method also consistently demonstrates a high recognition rate.

The Inventory of College Challenges for Ethnic Minority Students (ICCEMS) is a newly developed instrument that assesses challenges faced by ethnic minority college students across a range of cultural, academic, social, and practical domains. The present study tested the ICCEMS among Chinese American students in an attempt to identify its factor structure and assess its psychometric properties. A total of 13 factor domains emerged. The Cronbach's alpha and 1-month test-retest reliability of the subscales and the overall scale supported their reliability. Both criterion and construct validities were also demonstrated. Chinese American college students faced the greatest challenges in terms of unclear career direction and academic demands. 2004 APA

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.

During the creation of a university digital library and press intended to serve as a medical reference and education tool for health care providers and their patients, six distinct and complex digital publishing challenges were encountered. Over nine years, through a multidisciplinary approach, solutions were devised to the challenges of digital content ownership, management, mirroring, translation, interactions with users, and archiving. The result is a unique, author-owned, internationally mirrored, university digital library and press that serves as an authoritative medical reference and education tool for users around the world. The purpose of this paper is to share the valuable digital publishing lessons learned and outline the challenges facing university digital libraries and presses. PMID:10833161

Cross-cultural healthcare challenges: an insight into small American community hospitals.

The healthcare industry in the United States is faced with many strategic challenges, because of the nation's growing culturally diverse population. Growing cultural diversity now calls for better trained medical staff that is capable of handling language, religious and cultural differences. In the rural communities, where cultural diversity is rapidly becoming a demographic fact, small hospitals with limited resources are especially confronted with medical challenges for which they seem to be least prepared. Based on an exploratory research that includes a study of small town hospitals, this paper provides insights into cross-cultural problems facing healthcare professionals in small communities. The paper highlights also the ways in which hospitals are responding to such challenges.

Face-space: A unifying concept in face recognition research.

PubMed

Valentine, Tim; Lewis, Michael B; Hills, Peter J

2016-10-01

The concept of a multidimensional psychological space, in which faces can be represented according to their perceived properties, is fundamental to the modern theorist in face processing. Yet the idea was not clearly expressed until 1991. The background that led to the development of face-space is explained, and its continuing influence on theories of face processing is discussed. Research that has explored the properties of the face-space and sought to understand caricature, including facial adaptation paradigms, is reviewed. Face-space as a theoretical framework for understanding the effect of ethnicity and the development of face recognition is evaluated. Finally, two applications of face-space in the forensic setting are discussed. From initially being presented as a model to explain distinctiveness, inversion, and the effect of ethnicity, face-space has become a central pillar in many aspects of face processing. It is currently being developed to help us understand adaptation effects with faces. While being in principle a simple concept, face-space has shaped, and continues to shape, our understanding of face perception.

Tolerance to spatial-relational transformations in unfamiliar faces: A further challenge to a configural processing account of identity recognition.

PubMed

Lorenzino, Martina; Caminati, Martina; Caudek, Corrado

2018-05-25

One of the most important questions in face perception research is to understand what information is extracted from a face in order to recognize its identity. Recognition of facial identity has been attributed to a special sensitivity to "configural" information. However, recent studies have challenged the configural account by showing that participants are poor in discriminating variations of metric distances among facial features, especially for familiar as opposed to unfamiliar faces, whereas a configural account predicts the opposite. We aimed to extend these previous results by examining classes of unfamiliar faces with which we have different levels of expertise. We hypothesized an inverse relation between sensitivity to configural information and expertise with a given class of faces, but only for neutral expressions. By first matching perceptual discriminability, we measured tolerance to subtle configural transformations with same-race (SR) versus other-race (OR) faces, and with upright versus upside-down faces. Consistently with our predictions, we found a lower sensitivity to at-threshold configural changes for SR compared to OR faces. We also found that, for our stimuli, the face inversion effect disappeared for neutral but not for emotional faces - a result that can also be attributed to a lower sensitivity to configural transformations for faces presented in a more familiar orientation. The present findings question a purely configural account of face processing and suggest that the role of spatial-relational information in face processing varies according to the functional demands of the task and to the characteristics of the stimuli.
