Dopamine signaling occurs on a subsecond timescale, and its dysregulation is implicated in pathologies ranging from drug addiction to Parkinson’s disease. Anatomic evidence suggests that some dopamine neurons have cross-hemispheric projections, but the significance of these projections is unknown. Here we report unprecedented interhemispheric communication in the midbrain dopamine system of awake and anesthetized rats. In the anesthetized rats, optogenetic and electrical stimulation of dopamine cells elicited physiologically relevant dopamine release in the contralateral striatum. Contralateral release differed between the dorsal and ventral striatum owing to differential regulation by D2-like receptors. In the freely moving animals, simultaneous bilateral measurements revealed that dopamine release synchronizes between hemispheres and intact, contralateral projections can release dopamine in the midbrain of 6-hydroxydopamine–lesioned rats. These experiments are the first, to our knowledge, to show cross-hemispheric synchronicity in dopamine signaling and support a functional role for contralateral projections. In addition, our data reveal that psychostimulants, such as amphetamine, promote the coupling of dopamine transients between hemispheres. PMID:27298371

According to the Milankovitch theory, changes in summer insolation in the high-latitude Northern Hemisphere caused glacial cycles through their impact on ice-sheet mass balance. Statistical analyses of long climate records supported this theory, but they also posed a substantial challenge by showing that changes in Southern Hemisphere climate were in phase with or led those in the north. Although an orbitally forced Northern Hemisphere signal may have been transmitted to the Southern Hemisphere, insolation forcing can also directly influence local Southern Hemisphere climate, potentially intensified by sea-ice feedback, suggesting that the hemispheres may have responded independently to different aspects of orbital forcing. Signal processing of climate records cannot distinguish between these conditions, however, because the proposed insolation forcings share essentially identical variability. Here we use transient simulations with a coupled atmosphere-ocean general circulation model to identify the impacts of forcing from changes in orbits, atmospheric CO(2) concentration, ice sheets and the Atlantic meridional overturning circulation (AMOC) on hemispheric temperatures during the first half of the last deglaciation (22-14.3 kyr BP). Although based on a single model, our transient simulation with only orbital changes supports the Milankovitch theory in showing that the last deglaciation was initiated by rising insolation during spring and summer in the mid-latitude to high-latitude Northern Hemisphere and by terrestrial snow-albedo feedback. The simulation with all forcings best reproduces the timing and magnitude of surface temperature evolution in the Southern Hemisphere in deglacial proxy records. AMOC changes associated with an orbitally induced retreat of Northern Hemisphere ice sheets is the most plausible explanation for the early Southern Hemisphere deglacial warming and its lead over Northern Hemisphere temperature; the ensuing rise in atmospheric CO(2

Secondary Teacher and University Partnerships: Does Being in a Partnership Create Teacher Partners?

Science.gov (United States)

Burrows, Andrea C.

The purpose of this research was to understand how individuals, specifically secondary teachers and graduate engineering students, developed a working relationship in a grant funded project. I investigated three interrelated research questions about partnerships including: 1) What is the meaning of partnership to each individual? 2) How do the individuals negotiate the work in their partnership? and 3) Do the individual conceptions of partnership change as a result of their interactions? I used a qualitative descriptive case study methodology. I conducted nine interviews, four focus groups, 33 classroom field note observations, and collected emails. I detailed each of the three cases, and I conducted a cross case analysis of the three schools. I compared the similarities and differences between the cases in order to understand the partnership themes that defined a specific case and those that were generalized to several cases. Using grounded theory, my overall findings showed that each case generated six themes. These themes included product, perspective, expectations, decision making, relationships, and habit. I explored all six themes in current literature, and five of the six themes were prevalent there. In my study, habit was the core phenomenon but was not as common in the literature. It was related to the socio-cognitive theory of knowledge construction and Bourdieu's habitus. Additionally, it was connected to the concept of change in partnerships.

Split-brain, the right hemisphere, and art: fact and fiction.

Zaidel, Dahlia W

2013-01-01

The research studies of complete commissurotomy patients (split-brain) in Roger W. Sperry's psychobiology laboratory at Caltech, Pasadena, galvanized the scientific and intellectual world in the 1960s and 1970s. The findings had an important and enduring impact on brain research in countless areas. Interest in hemispheric specialization in particular was sparked by these studies and paved the way for countless discoveries. Right hemisphere specialization for visuospatial functions and facial processing was confirmed with these patients. The further unraveling of right-hemisphere cognition, the "mute" hemisphere, was a major goal in Sperry's laboratory, and much factual knowledge was learned that was not known previously. However, the linking of art and creativity with the right hemisphere was a nonempirically based inference made not by Sperry's lab but rather by others wishing to "assign" functional hemisphericity. The general assumption was that "art" is anchored in spatial cognition, that it is a nonverbal activity requiring imagery and thus must be controlled by the right, nonlanguage hemisphere. To this day, robust evidence that the right specializes in art expression or art perception is yet to be shown, if for no other reason than that art is not a single, unitary form of expression or cognition. The conjectured right hemisphere-art link turned into a popular story that filtered back into science, shaped future research of brain and art, and overlooked other avenues for insights.

Kang, Moon Jung; Park, Jihyoun

2013-01-01

The clean development mechanism (CDM) is a global collaborative action proposed at the Kyoto Protocol in response to climate change issues. The CDM contributes to cost-efficient reduction of greenhouse gas emissions in industrialized countries and promotes sustainable development in developing countries. Its fundamental framework is based on partnerships between industrialized and developing countries. This study employs social network analysis to investigate the dynamics of the partnership networks observed in 3816 CDM projects registered in the database of the United Nations Framework Convention on Climate Change over the period of 2005 to 2011. Our three main findings can be summarized as follows. First, the CDM partnership network is a small world; however, its density tends to decrease as the number of participants for a CDM project decreases. Second, the partnership networks’ leading groups tend to shift from partner countries into host countries. Third, a host country that pursues more partnership-based projects takes better control of resources and knowledge-flow in the ego-network formed around that country, and can thus better utilize global resources for its CDM projects. - Highlights: ► We investigate dynamics of the international partnership networks of CDM projects. ► The density of CDM networks tends to decrease by time. ► The partnership networks’ leading groups tend to shift into host countries. ► A host country with more partnerships better utilizes global knowledge resources.

Research funding is increasingly supporting collaborations between knowledge users and researchers. Partnering Healthy@Work (pH@W), an inaugural recipient of funding through Australia's Partnership for Better Health Grants scheme, was a 5-year partnership between the Menzies Institute for Medical Research, University of Tasmania and the Tasmanian State Service (TSS). The partnerships purpose was to evaluate a comprehensive workplace health promotion programme (Healthy@Work) targeting 30 000 public sector employees; generating new knowledge and influencing workplace health promotion policy and decision-making. This mixed methods study evaluates the partnership between policy-makers and academics and identifies strategies that enabled pH@W to deliver key project outcomes. A pH@W document review was conducted, two partnership assessment tools completed and semi-structured interviews conducted with key policy-makers and academics. Analysis of the partnership assessment tools and interviews found that pH@W had reached a strong level of collaboration. Policy-relevant knowledge was generated about the health of TSS employees and their engagement with workplace health promotion. Knowledge exchange of a conceptual and instrumental nature occurred and was facilitated by the shared grant application, clear governance structures, joint planning, regular information exchange between researchers and policy-makers and research student placements in the TSS. Flexibility and acknowledgement of different priorities and perspectives of partner organizations were identified as critical factors for enabling effective partnership working and research relevance. Academic-policy-maker partnerships can be a powerful mechanism for improving policy relevance of research, but need to incorporate strategies that facilitate regular input from researchers and policy-makers in order to achieve this. © The Author 2016.

Effective knowledge management as basis for holistic knowledge engineering – Knowledge as the key asset of an organization

Directory of Open Access Journals (Sweden)

Svetlana Lazović

2013-03-01

Full Text Available In knowledge management , human resources are in the foreground and their value is constantly rising. In the eyes of modern managers knowledge is the key asset of an organization. Effective management and management of knowledge processes are central preoccupations of modern managers and, at the same time, the most prominent feature of a knowledge-based organization. Like innovation and creativity, knowledge needs to be encouraged and treated with due care. Commitment to acquisition of new knowledge depends on how the interpersonal relationships are managed in an organization, therefore, those responsible for knowledge processes, the so-called modern knowledge managers, will develop partnership relation- ships with all members of their organization. In the core of such partnerships lie competences of individual employees and their creative application of knowledge. By encouraging learning, discussions and opinion exchange as well as personal and professional growth of their employees, management in knowledge-based organizations is improving the quality of work, and consequently, generation of new knowledge and their organization’s competitive advantage.

Communicating facts through third-party partnerships

Every day in the United States people are making decisions about the future of nuclear energy, while it continues to be one of our most controversial issues. How these decisions turn out and whether they are based on fact and need or fear and misconceptions will depend in large part on how active a role knowledgeable people choose to play in the public arena. The participation of scientists and engineers, industry employees, and operators is particularly important because of the respect the public has for their knowledge of the issues. There are a number of very successful programs in which individuals participate through meaningful partnerships with larger national public information efforts. This paper reviews two such partnership programs and makes generalized conclusions about their success and their importance

The non-linear development of the right hemispheric specialization for human face perception.

Lochy, Aliette; de Heering, Adélaïde; Rossion, Bruno

The developmental origins of human adults' right hemispheric specialization for face perception remain unclear. On the one hand, infant studies have shown a right hemispheric advantage for face perception. On the other hand, it has been proposed that the adult right hemispheric lateralization for face perception slowly emerges during childhood due to reading acquisition, which increases left lateralized posterior responses to competing written material (e.g., visual letters and words). Since methodological approaches used in infant and children typically differ when their face capabilities are explored, resolving this issue has been difficult. Here we tested 5-year-old preschoolers varying in their level of visual letter knowledge with the same fast periodic visual stimulation (FPVS) paradigm leading to strongly right lateralized electrophysiological occipito-temporal face-selective responses in 4- to 6-month-old infants (de Heering and Rossion, 2015). Children's face-selective response was quantitatively larger and differed in scalp topography from infants', but did not differ across hemispheres. There was a small positive correlation between preschoolers' letter knowledge and a non-normalized index of right hemispheric specialization for faces. These observations show that previous discrepant results in the literature reflect a genuine nonlinear development of the neural processes underlying face perception and are not merely due to methodological differences across age groups. We discuss several factors that could contribute to the adult right hemispheric lateralization for faces, such as myelination of the corpus callosum and reading acquisition. Our findings point to the value of FPVS coupled with electroencephalography to assess specialized face perception processes throughout development with the same methodology.

Onsite-effects of dual-hemisphere versus conventional single-hemisphere transcranial direct current stimulation

Science.gov (United States)

Kwon, Yong Hyun; Jang, Sung Ho

2012-01-01

We performed functional MRI examinations in six right-handed healthy subjects. During functional MRI scanning, transcranial direct current stimulation was delivered with the anode over the right primary sensorimotor cortex and the cathode over the left primary sensorimotor cortex using dual-hemispheric transcranial direct current stimulation. This was compared to a cathode over the left supraorbital area using conventional single-hemispheric transcranial direct current stimulation. Voxel counts and blood oxygenation level-dependent signal intensities in the right primary sensorimotor cortex regions were estimated and compared between the two transcranial direct current stimulation conditions. Our results showed that dual-hemispheric transcranial direct current stimulation induced greater cortical activities than single-hemispheric transcranial direct current stimulation. These findings suggest that dual-hemispheric transcranial direct current stimulation may provide more effective cortical stimulation than single-hemispheric transcranial direct current stimulation.

The neural mechanisms underlying recovery of language after left hemisphere stroke remain elusive. Although older evidence suggested that right hemisphere language homologues compensate for damage in left hemisphere language areas, the current prevailing theory suggests that right hemisphere engagement is ineffective or even maladaptive. Using a novel combination of support vector regression-based lesion-symptom mapping and voxel-based morphometry, we aimed to determine whether local grey matter volume in the right hemisphere independently contributes to aphasia outcomes after chronic left hemisphere stroke. Thirty-two left hemisphere stroke survivors with aphasia underwent language assessment with the Western Aphasia Battery-Revised and tests of other cognitive domains. High-resolution T1-weighted images were obtained in aphasia patients and 30 demographically matched healthy controls. Support vector regression-based multivariate lesion-symptom mapping was used to identify critical language areas in the left hemisphere and then to quantify each stroke survivor’s lesion burden in these areas. After controlling for these direct effects of the stroke on language, voxel-based morphometry was then used to determine whether local grey matter volumes in the right hemisphere explained additional variance in language outcomes. In brain areas in which grey matter volumes related to language outcomes, we then compared grey matter volumes in patients and healthy controls to assess post-stroke plasticity. Lesion–symptom mapping showed that specific left hemisphere regions related to different language abilities. After controlling for lesion burden in these areas, lesion size, and demographic factors, grey matter volumes in parts of the right temporoparietal cortex positively related to spontaneous speech, naming, and repetition scores. Examining whether domain general cognitive functions might explain these relationships, partial correlations demonstrated that grey matter

The need for better partnerships between Aboriginal organisations and mainstream agencies demands attention on process and relational elements of these partnerships, and improving partnership functioning through transformative or iterative evaluation procedures. This paper presents the findings of a literature review which examines the usefulness of existing partnership tools to the Australian Aboriginal-mainstream partnership (AMP) context. Three sets of best practice principles for successful AMP were selected based on authors' knowledge and experience. Items in each set of principles were separated into process and relational elements and used to guide the analysis of partnership assessment tools. The review and analysis of partnership assessment tools were conducted in three distinct but related parts. Part 1- identify and select reviews of partnership tools; part 2 - identify and select partnership self-assessment tool; part 3 - analysis of selected tools using AMP principles. The focus on relational and process elements in the partnership tools reviewed is consistent with the focus of Australian AMP principles by reconciliation advocates; however, historical context, lived experience, cultural context and approaches of Australian Aboriginal people represent key deficiencies in the tools reviewed. The overall assessment indicated that the New York Partnership Self-Assessment Tool and the VicHealth Partnership Analysis Tools reflect the greatest number of AMP principles followed by the Nuffield Partnership Assessment Tool. The New York PSAT has the strongest alignment with the relational elements while VicHealth and Nuffield tools showed greatest alignment with the process elements in the chosen AMP principles. Partnership tools offer opportunities for providing evidence based support to partnership development. The multiplicity of tools in existence and the reported uniqueness of each partnership, mean the development of a generic partnership analysis for AMP

The process of joint evaluation involving several actors is criss-crossed by a process of negotiation and adjustment between different concerns, responsibilities and interests. How can we encourage a dialogue between knowledge from expertise and knowledge from experience, in order to produce knowledge that is scientifically based and useful for those who are involved in the programs? Far from being a mechanical process, this involves the delicate task of striking a balance, which relies on a negotiated partnership framework. The implementation of an advisory committee, organized by an interface function between the stakeholders of the intervention under study, has increasingly become recognized as a necessary condition for success in partnership-based research. These conditions enable the deployment of a reflexive system that can support social innovation--when the formulation of the problem and its resulting actions become enriched, as knowledge about the intervention develops.

The FTAA and hemispheric integration: building a triple-win strategy for trade and sustainability in the hemisphere

International Nuclear Information System (INIS)

2001-04-01

The concept of a trade and sustainability agenda for the Americas is explained and a historical account of the process of making this concept a reality is discussed in a background paper for the Hemispheric Trade and Sustainability Symposium held on April 18, 2001 in Quebec City. The Symposium was held in conjunction with the Third Summit of the Americas, where heads of 34 American nations discussed ways and means to encourage hemispheric cooperation. The object of the Symposium was to provide a constructive, policy-oriented, and knowledge-based open forum for dialogue on trade and sustainability issues; to identify policy options that can be mutually beneficial to trade, environment and development, and to increase public support for trade liberalisation in the Americas. The strategy aims to build a sustainable FTAA through the identification of a series of environmental provisions to be incorporated in the Agreement; strengthen environmental cooperation in the Americas, especially in trade-sensitive, or trade-related sectors, and create a high level hemispheric expert group on trade and sustainability for continuous and constructive dialogue with civil society and industry on these issues. The backgrounder provides a precis of the fundamental aspect of building a sustainable FTAA, explains the origin of the prevailing fear of unilateral environment-related trade sanctions by the United States, the fear of protectionist measures by Canada and the United States based on environmental provisions in the FTAA, and the fear that higher environmental standards and regulations would undermine the competitiveness of Latin American and Caribbean businesses. The paper attempts to dispel these fears by explaining the mechanism envisaged to be predominant in creating the triple-win strategy, namely impact assessment, transparency, participation and dispute resolution processes. The eventual agreement should also mention sustainable development as an overarching objective of

Issue addressed Partnerships were used to increase healthy eating and active living in children for the Obesity Prevention and Lifestyle (OPAL) program, a systems-wide, community-based childhood obesity prevention program in South Australia. This part of the multi-component evaluation examines stakeholders' perceptions of how OPAL staff worked in partnership and factors contributing to strong partnerships. Methods Pre- and post-interviews and focus groups with multi-sector stakeholders (n=131) across six OPAL communities were analysed using NVivo8 qualitative data analysis software. Results Stakeholders reflected positively on projects developed in partnership with OPAL, reporting that staff worked to establish co-benefits. They identified several factors that contributed to the strengthening of partnerships: staff skills, visibility, resources and sustainability. Conclusions Rather than implementing projects with stakeholders with shared organisational goals, local shared projects were implemented that included a breadth of co-benefits, allowing multi-sector stakeholders to meet their own organisational goals. Practitioners who have the capacity to be flexible, persistent, knowledgeable and skilled communicators are required to negotiate projects, achieving benefit for both health and stakeholders' organisational goals. So what? Engaging in partnership practice to broker co-benefits at the micro or program level has been an effective model for community engagement and change in OPAL. It foregrounds the need for the inclusion of value to partners, which differs from situations in which organisations come together around common goals.

Reorganization of syntactic processing following left-hemisphere brain damage: does right-hemisphere activity preserve function?

2010-11-01

The extent to which the human brain shows evidence of functional plasticity across the lifespan has been addressed in the context of pathological brain changes and, more recently, of the changes that take place during healthy ageing. Here we examine the potential for plasticity by asking whether a strongly left-lateralized system can successfully reorganize to the right-hemisphere following left-hemisphere brain damage. To do this, we focus on syntax, a key linguistic function considered to be strongly left-lateralized, combining measures of tissue integrity, neural activation and behavioural performance. In a functional neuroimaging study participants heard spoken sentences that differentially loaded on syntactic and semantic information. While healthy controls activated a left-hemisphere network of correlated activity including Brodmann areas 45/47 and posterior middle temporal gyrus during syntactic processing, patients activated Brodmann areas 45/47 bilaterally and right middle temporal gyrus. However, voxel-based morphometry analyses showed that only tissue integrity in left Brodmann areas 45/47 was correlated with activity and performance; poor tissue integrity in left Brodmann area 45 was associated with reduced functional activity and increased syntactic deficits. Activity in the right-hemisphere was not correlated with damage in the left-hemisphere or with performance. Reduced neural integrity in the left-hemisphere through brain damage or healthy ageing results in increased right-hemisphere activation in homologous regions to those left-hemisphere regions typically involved in the young. However, these regions do not support the same linguistic functions as those in the left-hemisphere and only indirectly contribute to preserved syntactic capacity. This establishes the unique role of the left hemisphere in syntax, a core component in human language.

Workshop: Western hemisphere network of bird banding programs

Purpose: To promote collaboration among banding programs in the Americas. Introduction: Bird banding and marking provide indispensable tools for ornithological research, management, and conservation of migratory birds on migratory routes, breeding and non-breeding grounds. Many countries and organizations in Latin America and the Caribbean are in the process of developing or have expressed interest in developing national banding schemes and databases to support their research and management programs. Coordination of developing and existing banding programs is essential for effective data management, reporting, archiving and security, and most importantly, for gaining a fuller understanding of migratory bird conservation issues and how the banding data can help. Currently, there is a well established bird-banding program in the U.S.A. and Canada, and programs in other countries are being developed as well. Ornithologists in many Latin American countries and the Caribbean are interested in using banding and marking in their research programs. Many in the ornithological community are interested in establishing banding schemes and some countries have recently initiated independent banding programs. With the number of long term collaborative and international initiatives increasing, the time is ripe to discuss and explore opportunities for international collaboration, coordination, and administration of bird banding programs in the Western Hemisphere. We propose the second ?Western Hemisphere Network of Bird Banding Programs? workshop, in association with the SCSCB, to be an essential step in the progress to strengthen international partnerships and support migratory bird conservation in the Americas and beyond. This will be the second multi-national meeting to promote collaboration among banding programs in the Americas (the first meeting was held in October 8-9, 2006 in La Mancha, Veracruz, Mexico).

Pre- or perinatally acquired ("congenital") left-hemispheric brain lesions can be compensated for by reorganizing language into homotopic brain regions in the right hemisphere. Language comprehension may be hemispherically dissociated from language production. We investigated the lesion characteristics driving inter-hemispheric reorganization of language comprehension and language production in 19 patients (7-32years; eight females) with congenital left-hemispheric brain lesions (periventricular lesions [n=11] and middle cerebral artery infarctions [n=8]) by fMRI. 16/17 patients demonstrated reorganized language production, while 7/19 patients had reorganized language comprehension. Lesions to the insular cortex and the temporo-parietal junction (predominantly supramarginal gyrus) were significantly more common in patients in whom both, language production and comprehension were reorganized. These areas belong to the dorsal stream of the language network, participating in the auditory-motor integration of language. Our data suggest that the integrity of this stream might be crucial for a normal left-lateralized language development. Copyright © 2017. Published by Elsevier Inc.

Communication Impairments in Patients with Right Hemisphere Damage

Directory of Open Access Journals (Sweden)

Abusamra, Valeria

2009-06-01

Full Text Available Right brain damages can manifest deficits of communicative skills, which sometimes cause an important inability.The communication impairments following a right hemisphere damage are distinct from those in aphasia and may affect discursive, lexico-semantic, pragmatic, and prosodic components of communication. It is calculated that this troubles affect almost a 50% of this patients.However, these impairments have essentially been studied separately and their possible coexistence in a same individual is still unknown. Moreover, the clinical profiles of communication impairments following a right hemisphere damage, including their correlation with underlying cognitive deficits, are still unreported. The goal of this article is to offer an overview of the verbal communication deficits that can be found in right-hemisphere-damaged individuals. These deficits can interfere, at different levels, with prosody, the semantic processing of words and discourse and pragmatic abilities. In spite of the incapability that they produce, communicational impairments in right brain damaged are usually neglected. Probably, the sub-diagnostic is due to the lack of an appropriate classification or to the absent of adequate assessment tools. In fact, patients with right brain damages might present harsh communicational deficits but perform correctly on aphasia tests because the last ones are not designed to detect this kind of deficit but left brain damaged impairments. Increasing our knowledge about the role of the right-hemisphere in verbal communication will have major theoretical and clinical impacts; it could facilitate the diagnosis of right brain patients in the clinical circle and it will help to lay the foundations to elaborate methods and strategies of intervention.

Despite the quantity of research on child and adolescent mental health being done in schools, little output has focused on the practical aspects of recruiting schools and students into a study. Furthermore, there is limited knowledge on how to develop and sustain productive and mutually beneficial partnerships with schools after the project finishes. A large study examining prevalence of mental health problems in young people involving nine schools is used as an example for the procedure of recruitment and carrying out a research project, while developing and sustaining partnerships with schools. While recruiting the schools, a three-stage model was developed that corresponded closely to the school's needs and existing demands. The suggested procedure for the study, thus, closely reflected the varying existing cultures of participating schools. Partnerships, developed as a result of the project, were used in developing further projects and interventions for promoting good mental health in schools. Rather than a blanket research recruitment and procedural approach with an end to school involvement at the end of the project, the paper advocates for a deeper understanding of the schools' internal culture for improved recruitment and study outcomes. Developed partnerships, when sustained past the completion of research, prove to be a useful tool in applying the findings in promoting good mental health in schools and continuing research further.

An Investigation of the Dayton Regional STEM School Public-Private Partnerships

Science.gov (United States)

Poole, Kimberly S.

This dissertation study documents in-depth the exploration of the Public Private Partnerships (PPPs) between the Dayton Regional STEM School (DRSS) and their industry partners as well as the establishment of a framework for evaluating and assessing PPPs. The public-private partnership agreements were studied in order to answer the over-arching research question: How is an effective public-private partnership established, assessed, and evaluated in education? A descriptive case study methodology was used to study DRSS' public-private partnership agreements to determine if goals and objectives were established and whether or not the partnerships met those goals and objectives. This case study also included the development and testing of a proposed evaluation framework that will allow for consistent, systematic inquiry that can produce defensible assertions regarding the assessment and evaluation of public-private partnerships in education. Results of the case study support the findings that utilization of an evaluation framework can serve to make public-private partnerships more successful. Results also indicated that establishment of goals and objectives enable effective evaluation for informal partnerships but could not be definitively stated for formal partnerships due to the lack of data points. The data from this case study revealed many emergent themes that should be considered in the development of future public-private partnerships. Overall this study contributes to the growing body of knowledge for public-private partnerships in education.

Hemispheric processing asymmetries: implications for memory.

Science.gov (United States)

Funnell, M G; Corballis, P M; Gazzaniga, M S

2001-01-01

Recent research has demonstrated that memory for words elicits left hemisphere activation, faces right hemisphere activation, and nameable objects bilateral activation. This pattern of results was attributed to dual coding of information, with the left hemisphere employing a verbal code and the right a nonverbal code. Nameable objects can be encoded either verbally or nonverbally and this accounts for their bilateral activation. We investigated this hypothesis in a callosotomy patient. Consistent with dual coding, the left hemisphere was superior to the right in memory for words, whereas the right was superior for faces. Contrary to prediction, performance on nameable pictures was not equivalent in the two hemispheres, but rather resulted in a right hemisphere superiority. In addition, memory for pictures was significantly better than for either words or faces. These findings suggest that the dual code hypothesis is an oversimplification of the processing capabilities of the two hemispheres.

Globalization is creating an interdependent space-faring world and new opportunities for international partnerships that strengthen space knowledge development and transfer. These opportunities have been codified in the Global Exploration Strategy, which endorses the "inspirational and educational value of space exploration" [1]. Also, during the 2010 Heads of Space Agencies Summit celebrating the International Academy of Astronautics' (IAA) 50th Anniversary, space-faring nations from across the globe issued a collective call in support of robust international partnerships to expand the frontiers of space exploration and generate knowledge for improving life on Earth [2]. Educators play a unique role in this mission, developing strategic partnerships and sharing best educational practices to (1) further global understanding of the benefits of space exploration for life on Earth and (2) prepare the next generation of scientists required for the 21st Century space workforce. Educational Outreach (EO) programs use evidence-based, measurable outcomes strategies and cutting edge information technologies to transfer space-based science, technology, engineering and mathematics (STEM) knowledge to new audiences; create indigenous materials with cultural resonance for emerging space societies; support teacher professional development; and contribute to workforce development initiatives that inspire and prepare new cohorts of students for space exploration careers. The National Space Biomedical Research Institute (NSBRI), the National Aeronautics and Space Administration (NASA) and Morehouse School of Medicine (MSM) have sustained a 13-year space science education partnership dedicated to these objectives. This paper briefly describes the design and achievements of NSBRI's educational programs, with special emphasis on those initiatives' involvement with IAA and the International Astronautical Congress (IAC). The IAA Commission 2 Draft Report, Space for Africa, is discussed

Echevarria, Mercedes

A knowledge translation project involving an academic-practice partnership and guided by action-oriented research was used for exploring barriers that impact management of homebound heart failure patients. The intervention process followed an action research model of interaction, self-reflection, response, and change in direction. External facilitators (academia) and internal facilitators (practice) worked with clinicians to identify a topic for improvement, explore barriers, locate the evidence compare current practice against evidence-based practice recommendations, introduce strategies to "close the gap" between actual practice and the desired practice, develop audit criteria, and reevaluate the impact.

Choosing words: left hemisphere, right hemisphere, or both? Perspective on the lateralization of word retrieval

Science.gov (United States)

Ries, Stephanie K.; Dronkers, Nina F.; Knight, Robert T.

2015-01-01

Language is considered to be one of the most lateralized human brain functions. Left hemisphere dominance for language has been consistently confirmed in clinical and experimental settings and constitutes one of the main axioms of neurology and neuroscience. However, functional neuroimaging studies are finding that the right hemisphere also plays a role in diverse language functions. Critically, the right hemisphere may also compensate for the loss or degradation of language functions following extensive stroke-induced damage to the left hemisphere. Here, we review studies that focus on our ability to choose words as we speak. Although fluidly performed in individuals with intact language, this process is routinely compromised in aphasic patients. We suggest that parceling word retrieval into its sub-processes—lexical activation and lexical selection—and examining which of these can be compensated for after left hemisphere stroke can advance the understanding of the lateralization of word retrieval in speech production. In particular, the domain-general nature of the brain regions associated with each process may be a helpful indicator of the right hemisphere's propensity for compensation. PMID:26766393

PHARMACEUTICAL PARTNERSHIPS IN THE DEVELOPMENT OF NEW PHARMACEUTICALS

Directory of Open Access Journals (Sweden)

A. L. Bulgakov

2018-01-01

Full Text Available This article examines the causes for creating alliances between manufacturers and drug developers. The attention has also been paid to the classification of such partnerships depending on the level of integration. The classification is necessary for further study of relations in the alliances. It is important to understand how economically effective and justified such partnerships are. The aim of the study is to determine the reasons for creating partnerships between drug developers and manufacturers, and to work out a classification of partnerships in the field of pharmacology. Materials and methods. The study analyzes existing alliances, partnerships of Big Pharma companies such as Bayer AG, Merck & Co, Pfizer. Results and discussion. The variety of forms of partnerships allows all participants in this market to get from cooperation the benefits they need. Some seek to reduce risk, others look forward to gaining access to new research opportunities, the third seek to share knowledge for greater productivity. However, there is always the opposite side, they have to sacrifice something to get a market advantage. For example, increased integration leads to a reduction in the risk of drug creation, but also leads to a decrease in the company’s independence. Conclusion. The results of this study can be used later in the study of the financial effectiveness of pharmaceutical partnerships, as well as in exploring the causes of alliances’ collapses. Any partnership has its value and can be considered as an intangible asset of the company. However, at the moment, there is no universal way of assessing this type of active assets, therefore, classification is a key step in creating a model for determining the value of a partnership. 

A critical evaluation of partnerships in municipal waste management in England

Partnership working is becoming popular as a strategic and operational approach to developing sustainable waste management. However, the evidence base to support partnership working is poor and the impact and potential of partnerships in the waste sector has not been analysed and assessed. This paper starts to address the gap in knowledge. It focuses on partnership working for the management of municipal waste, and identifies and characterises a range of different types including partnerships between local authorities and between local authorities and their service providers. Five models of partnerships are presented and illustrated through case studies. The paper is novel in applying an analytical framework for partnership working developed in healthcare [Hudson B, Hardy B. What is 'successful' partnership and how can it be measured? In: Glendinning C, Powell M, Rummery K, editors. Partnerships, New labour and the governance of welfare. Bristol: The Policy Press; 2002] to the public service delivery of waste and recycling services. The theoretical concepts of synergy and governance are used to inform this analysis and discuss the implications arising from emerging trends. Partnerships have defined members, a written understanding, a shared vision and a joint commitment to work together towards common objectives. Findings suggest successful partnerships have developed over the long-term, a partnership lifecycle exists where motivations, characteristics and activities change over time. Current partnerships appear to be primarily concerned with meeting targets and delivering efficiencies, which can lead towards more centralised decision making and aggregated services. We suggest that policy rhetoric promoting partnerships for delivering sustainable resource management and as a local governance mechanism is not borne out in practice and should be treated with caution.

2012-04-01

Throughout the world, climate services are required to address urgent needs for climate-informed decision-making, policy and planning. These needs were explored in detail at the first International Conference on Climate Services (ICCS), held in New York in October 2011. After lengthy discussions of needs and capabilities, the conference culminated in the creation of the Climate Services Partnership (CSP). The CSP is an informal interdisciplinary network of climate information users, providers, donors and researchers interested in improving the provision and development of climate services worldwide. Members of the Climate Services Partnership work together to share knowledge, accelerate learning, develop new capacities, and establish good practices. These collaborative efforts will inform and support the evolution and implementation of the Global Framework for Climate Services. The Climate Services Partnership focuses its efforts on three levels. These include: 1. encouraging and sustaining connections between climate information providers, users, donors, and researchers 2. gathering, synthesizing and disseminating current knowledge on climate services by way of an online knowledge management platform 3. generating new knowledge on critical topics in climate service development and provision, through the creation of focused working groups on specific topics To date, the Climate Services Partnership has made progress on all three fronts. Connections have been fostered through outreach at major international conferences and professional societies. The CSP also maintains a website and a monthly newsletter, which serves as a resource for those interested in climate services. The second International Conference on Climate Services (ICCS2) will be held in Berlin in September. The CSP has also created a knowledge capture system that gathers and disseminates a wide range of information related to the development and provision of climate services. This includes an online

To support reduction of racial disparities in mental health diagnosis and treatment, mental health researchers and black community-based organization (CBO) leaders need training on how to engage in collaborative research partnerships. In this study, we pilot tested a series of partnership skills training modules for researchers and CBO leaders in a collaborative learning format. Two different sets of three modules, designed for separate training of researchers and CBO leaders, covered considering, establishing and managing mental health research partnerships and included instructions for self-directed activities and discussions. Eight CBO leaders participated in 10 sessions, and six researchers participated in eight sessions. The effectiveness of the training content and format was evaluated through standardized observations, focus group discussions, participant evaluation forms and retrospective pre-/posttests to measure perceived gains in knowledge. Participants generally were satisfied with the training experience and gained new partnership knowledge and skills. Although the CBO leaders were more engaged in the cooperative learning process, this training format appealed to both audiences. Pilot testing demonstrated that: 1) our modules can equip researchers and CBO leaders with new partnership knowledge and skills and 2) the cooperative learning format is a well-received and suitable option for mental health research partnership training.

Unilateral Hemispheric Encephalitis

Full Text Available A 10 year old boy presented with history of mild fever and upper respiratory symptoms followed by recurrent seizures and loss of consciousness on the next day. Normal blood counts and abnormal hepatic transaminases were noted. MRI of the brain, done on the fourth day of illness, showed extensive involvement of the cortex in the right hemisphere. Lumbar CSF was normal. The EEG showed bilateral slowing with frontal sharp wave discharges and marked attenuation over the entire right hemisphere. The patient succumbed to the illness on the ninth day. A similar pattern of acute unilateral hemispheric cortical involvement is described in the hemiconvulsion-hemiplegia-epilepsy (HHE syndrome, which is typically described to occur in children below 4 years of age. This case of fulminant acute unilateral encaphilitic illness could represent the acute phase of HHE syndrome.

Onsite-effects of dual-hemisphere versus conventional single-hemisphere transcranial direct current stimulation: A functional MRI study.

Science.gov (United States)

Kwon, Yong Hyun; Jang, Sung Ho

2012-08-25

We performed functional MRI examinations in six right-handed healthy subjects. During functional MRI scanning, transcranial direct current stimulation was delivered with the anode over the right primary sensorimotor cortex and the cathode over the left primary sensorimotor cortex using dual-hemispheric transcranial direct current stimulation. This was compared to a cathode over the left supraorbital area using conventional single-hemispheric transcranial direct current stimulation. Voxel counts and blood oxygenation level-dependent signal intensities in the right primary sensorimotor cortex regions were estimated and compared between the two transcranial direct current stimulation conditions. Our results showed that dual-hemispheric transcranial direct current stimulation induced greater cortical activities than single-hemispheric transcranial direct current stimulation. These findings suggest that dual-hemispheric transcranial direct current stimulation may provide more effective cortical stimulation than single-hemispheric transcranial direct current stimulation.

A study of a museum-school partnership

Science.gov (United States)

Wojton, Mary Ann

Partnerships between museums and schools never have been more important than they are today. Schools, especially urban schools, are facing challenges, including low student achievement and difficulty obtaining funding. Partners can help schools overcome these challenges by sharing educational and financial resources. Nearly 11,000 American museums spend more than $1 billion annually to provide over 18 million instructional hours for k-12 educational programs such as professional development for teachers, guided field trips, and staff visits to schools. Museums would seem like natural partners for challenged urban schools. Yet museums and schools struggle to establish and maintain effective partnerships. This study examined a partnership between a science center and an urban elementary school to provide additional knowledge and resources for those in the field to overcome these challenges in order to create relationships that help students. Using qualitative methods with interpretive descriptive purposes (Erickson, 1986; Glesne, 1999; Lincoln & Guba, 2000), the research design is based on several methods of data collection, including face-to-face, semi-structured interviews; observations; written text; and field notes. Participants in this study included students, parents, teachers, school administrators and museum educators. In addition, adult representatives of community organizations were interviewed to determine the impact of the partnership on the community. The study found that an effective partnership will have four basic elements: mutual goals, communication plan, key leader support, planning and research, and four interpersonal elements: personal responsibility, honesty, communication at the intimate level, and trust. Partners may have difficulty developing these to their fullest extent due to time limitations. No partnership is perfect. By creating strong interpersonal relationships, partners can mitigate challenges caused by limited basic elements and

Quantifying the Comprehensive and Progressive Agreement for Trans-Pacific Partnership

Dan Ciuriak

2017-12-01

Full Text Available We assess the outcomes for the negotiating parties in the Trans-Pacific Partnership if the remaining eleven parties go ahead with the agreement as negotiated without the United States, as compared to the outcomes under the original twelve-member agreement signed in October 2016. We find that the eleven-party agreement, now renamed as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP, is a much smaller deal than the twelve-party one, but that some parties do better without the United States in the deal, in particular those in the Western Hemisphere-Canada, Mexico, Chile, and Peru. For the politically relevant medium term, the United States stands to be less well-off outside the TPP than inside. Since provisional deals can be in place for a long time, the results of this study suggest that the eleven parties are better off to implement the CPTPP, leaving aside the controversial governance elements, the implications of which for national interests are unclear and which, in any event, may be substantially affected by parallel bilateral negotiations between individual CPTPP parties and the United States.

Youth in Community Decision-Making: A Study of Youth-Adult Partnerships

Shelley Murdock

2008-03-01

Full Text Available Involving youth in community and organizational decision-making is widely believed to lead to stronger communities. A promising strategy to foster decision-making is youth-adult partnerships in which youth and adults work collaboratively, sharing their strengths, collective knowledge, and decision-making power. A qualitative study of eight youth organizations showed that those organizations employing youth-adult partnership strategies were most effective in increasing youth's contributions to their communities. This article explores the elements of youth-adult partnership that were evident among successful organizations including: mutual respect, meaningful roles for youth, unique contributions of adults and youth, and shared decision-making and implications for youth development programs.

Interaction of cerebral hemispheres and artistic thinking

Science.gov (United States)

Nikolaenko, Nikolay N.

1998-07-01

Study of drawings by patients with local lesions of the right or left hemisphere allows to understand how artistic thinking is supported by brain structures. The role of the right hemisphere is significant at the early stage of creative process. The right hemisphere is a generator of nonverbal visuo-spatial thinking. It operates with blurred nonverbal images and arrange them in a visual space. With the help of iconic signs the right hemisphere reflects the world and creates perceptive visual standards which are stored in the long-term right hemisphere memory. The image, which appeared in the `inner' space, should be transferred into a principally different language, i.e. a left hemispheric sign language. This language operates with a number of discrete units, logical succession and learned grammar rules. This process can be explained by activation (information) transfer from the right hemisphere to the left one. Thus, natural and spontaneous creative process, which is finished by a conscious effort, can be understood as an activation impulse transfer from the right hemisphere to the left one and back.

Aspects of Equality in Mandatory Partnerships - From the Perspective of Municipal Care in Norway.

Science.gov (United States)

Kirchhoff, Ralf; Ljunggren, Birgitte

2016-05-18

This paper raises questions about equality in partnerships, since imbalance in partnerships may effect collaboration outcomes in integrated care. We address aspects of equality in mandatory, public-public partnerships, from the perspective of municipal care. We have developed a questionnaire wherein the Norwegian Coordination Reform is an illustrative example. The following research question is addressed: What equality dimensions are important for municipals related to mandatory partnerships with hospitals? Since we did not find any instrument to measure equality in partnerships, an explorative design was chosen. The development of the instrument was based on the theory on partnership and knowledge about the field and context. A national online survey was emitted to all 429 Norwegian municipalities in 2013. The response rate was in total 58 percent (n = 248). The data were mainly analysed using Principal component analysis. It seems that the two dimensions "learning and expertise equality" and "contractual equality" collects reliable and valid data to measure aspects of equality in partnerships. Partnerships are usually based on voluntarism. The results indicate that mandatory partnerships, within a public health care system, can be appropriate to equalize partnerships between health care providers at different care levels.

Academic and service institutions involve with many challenges. Partnership programs are a golden opportunity to achieve mutual benefits to overcome these challenges. Identifying mutual benefits is the cornerstone of forming a successful partnership and guarantee to its continuity. There are definitions and instances of mutual benefits in the literature related to partnership programs, but there is no coherent evidence and clear picture of these benefits. This study is conducted to identify mutual benefits in academic-service partnership by analyzing the definitions and instances of it in the literature. An integrative review of key papers regarding mutual benefits in academic-service partnership was undertaken. This review was guided by the framework described by Whittemore and Knafl. Search of the following databases was conducted: MEDLINE, ERIC, Google Scholar, Emerald Insight and Science Direct. The search terms were mutual benefits, mutual gains, mutual interest, mutual expectations, mutual goals, mutual demand, partnership, collaboration, academic-service partnership and academic service collaboration. Cooper's five-stage integrative review method was used. Quality evaluation of articles was conducted. Data were abstracted from included articles. The analysis was conducted based on the qualitative content analysis of the literature suggested by Zhang and Wildemuth. 28 articles were included in this review. Mutual benefits are described in four categories include: synergy in training and empowerment of human resources, education improvement, access to shared resources, facilitate production and application of beneficial knowledge into practice. Mutual benefits in the academic-service partnership include a range of goals, interests, expectations, and needs of partner organizations that is achievable and measurable through joint planning and collaboration. We suggest academic and service policymakers to consider these benefits in the planning and evaluating

The isoprenoid pathway produces an endogenous membrane Na+-K+ ATPase inhibitor, digoxin, which can regulate neurotransmitter and amino acid transport. Digoxin synthesis and neurotransmitter patterns were assessed in eating disorders. The patterns were compared in those with right hemispheric and left hemispheric dominance. The serum HMG CoA reductase activity, RBC membrane Na+-K+ ATPase activity, serum digoxin, magnesium, tryptophan catabolites (serotonin, quinolinic acid, strychnine, and nicotine), and tyrosine catabolites (morphine, dopamine, and noradrenaline) were measured in anorexia nervosa, bulimia nervosa, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. Digoxin synthesis was increased with upregulated tryptophan catabolism and downregulated tyrosine catabolism in those with anorexia nervosa and right hemispheric chemical dominance. Digoxin synthesis was reduced with downregulated tryptophan catabolism and upregulated tyrosine catabolism in those with bulimia nervosa and left hemispheric chemical dominance. The membrane Na+-K+ ATPase activity and serum magnesium were decreased in anorexia nervosa and right hemispheric chemical dominance while they were increased in bulimia nervosa and left hemispheric chemical dominance. Hypothalamic digoxin and hemispheric chemical dominance play a central role in the regulation of eating behavior. Anorexia nervosa represents the right hemispheric chemically dominant/hyperdigoxinemic state and bulimia nervosa the left hemispheric chemically dominant/hypodigoxinemic state.

Accurate knowledge of infrared emissivity is important in applications such as surface temperature measurements by infrared thermography or thermal balance for building walls. A comparison of total hemispherical emissivity measurement was performed by two laboratories: the Laboratoire National de Métrologie et d'Essais (LNE) and the Centre d'Études et de Recherche en Thermique, Environnement et Systèmes (CERTES). Both laboratories performed emissivity measurements on four samples, chosen to cover a large range of emissivity values and angular reflectance behaviors. The samples were polished aluminum (highly specular, low emissivity), bulk PVC (slightly specular, high emissivity), sandblasted aluminum (diffuse surface, medium emissivity), and aluminum paint (slightly specular surface, medium emissivity). Results obtained using five measurement techniques were compared. LNE used a calorimetric method for direct total hemispherical emissivity measurement [1], an absolute reflectometric measurement method [2], and a relative reflectometric measurement method. CERTES used two total hemispherical directional reflectometric measurement methods [3, 4]. For indirect techniques by reflectance measurements, the total hemispherical emissivity values were calculated from directional hemispherical reflectance measurement results using spectral integration when required and directional to hemispherical extrapolation. Results were compared, taking into account measurement uncertainties; an added uncertainty was introduced to account for heterogeneity over the surfaces of the samples and between samples. All techniques gave large relative uncertainties for a low emissive and very specular material (polished aluminum), and results were quite scattered. All the indirect techniques by reflectance measurement gave results within ±0.01 for a high emissivity material. A commercial aluminum paint appears to be a good candidate for producing samples with medium level of emissivity

The HIV epidemic spreads among men who have sex with men (MSM) in China. The objective of this study was to examine and compare HIV/AIDS knowledge and sexual risk for HIV between MSM who engaged in concurrent sexual partnerships and MSM who did not. A cross-sectional study using respondent driven sampling was conducted among 351 MSM in Shenzhen, China. About half (49%) of respondents reported having concurrent sexual partnerships during the past 6 months. Among MSM with concurrent sexual partnerships, 62% had only male partners and 38% had both male and female partners. The proportion of inconsistent condom use was 42% among MSM with concurrent partners and 30% among MSM without. These 2 groups reported a similar level of self-perceived risk for HIV. Compared to MSM without concurrent sexual partners, those with such partners were more likely to work in entertainment venues and had a lower level of HIV/AIDS knowledge. The large number of MSM engaging in concurrent sexual partnerships and the high prevalence of bisexuality could accelerate the spread of HIV to the general population unless effective HIV interventions for MSM are implemented in China.

Global health partnership for student peer-to-peer psychiatry e-learning: Lessons learned.

Science.gov (United States)

Keynejad, Roxanne C

2016-12-03

Global 'twinning' relationships between healthcare organizations and institutions in low and high-resource settings have created growing opportunities for e-health partnerships which capitalize upon expanding information technology resources worldwide. E-learning approaches to medical education are increasingly popular but remain under-investigated, whilst a new emphasis on global health teaching has coincided with university budget cuts in many high income countries. King's Somaliland Partnership (KSP) is a paired institutional partnership health link, supported by Tropical Health and Education Trust (THET), which works to strengthen the healthcare system and improve access to care through mutual exchange of skills, knowledge and experience between Somaliland and King's Health Partners, UK. Aqoon, meaning knowledge in Somali, is a peer-to-peer global mental health e-learning partnership between medical students at King's College London (KCL) and Hargeisa and Amoud Universities, Somaliland. It aims to extend the benefits of KSP's cross-cultural and global mental health education work to medical students and has reported positive results, including improved attitudes towards psychiatry in Somaliland students. The process of devising, piloting, evaluating, refining, implementing, re-evaluating and again refining the Aqoon model has identified important barriers to successful partnership. This article describes lessons learned during this process, sharing principles and recommendations for readers wishing to expand their own global health link beyond qualified clinicians, to the healthcare professionals of the future.

Sleep Spindles in the Right Hemisphere Support Awareness of Regularities and Reflect Pre-Sleep Activations.

The present study explored the sleep mechanisms which may support awareness of hidden regularities. Before sleep, 53 participants learned implicitly a lateralized variant of the serial response-time task in order to localize sensorimotor encoding either in the left or right hemisphere and induce implicit regularity representations. Electroencephalographic (EEG) activity was recorded at multiple electrodes during both task performance and sleep, searching for lateralized traces of the preceding activity during learning. Sleep EEG analysis focused on region-specific slow (9-12 Hz) and fast (13-16 Hz) sleep spindles during nonrapid eye movement sleep. Fast spindle activity at those motor regions that were activated during learning increased with the amount of postsleep awareness. Independently of side of learning, spindle activity at right frontal and fronto-central regions was involved: there, fast spindles increased with the transformation of sequence knowledge from implicit before sleep to explicit after sleep, and slow spindles correlated with individual abilities of gaining awareness. These local modulations of sleep spindles corresponded to regions with greater presleep activation in participants with postsleep explicit knowledge. Sleep spindle mechanisms are related to explicit awareness (1) by tracing the activation of motor cortical and right-hemisphere regions which had stronger involvement already during learning and (2) by recruitment of individually consolidated processing modules in the right hemisphere. The integration of different sleep spindle mechanisms with functional states during wake collectively supports the gain of awareness of previously experienced regularities, with a special role for the right hemisphere. © Sleep Research Society 2017.

The right hemisphere is predominantly involved in tasks associated with spatial attention. However, left hemispheric dominance for spatial attention can be found in healthy individuals, and both spatial attention and language can be lateralized to the same hemisphere. Little is known about the underlying regional distribution of neural activation in these 'atypical' individuals. Previously a large number of healthy subjects were screened for hemispheric dominance of visuospatial attention and language, using functional Doppler ultrasonography. From this group, subjects were chosen who were 'atypical' for hemispheric dominance of visuospatial attention and language, and their pattern of brain activation was studied with functional magnetic resonance imaging during a task probing spatial attention. Right-handed subjects with the 'typical' pattern of brain organization served as control subjects. It was found that subjects with an inverted lateralization of language and spatial attention (language right, attention left) recruited left-hemispheric areas in the attention task, homotopic to those recruited by control subjects in the right hemisphere. Subjects with lateralization of both language and attention to the right hemisphere activated an attentional network in the right hemisphere that was comparable to control subjects. The present findings suggest that not the hemispheric side, but the intrahemispheric pattern of activation is the distinct feature for the neural processes underlying language and attention.

Hypothalamic digoxin, hemispheric chemical dominance and sarcoidosis.

Science.gov (United States)

Ravi Kumar, A; Kurup, Parameswara Achutha

2004-06-01

The isoprenoid pathway produces three key metabolites: endogenous digoxin (membrane sodium-potassium ATPase inhibitor, immunomodulator and regulator of neurotransmitter/amino acid transport), dolichol (regulates N-glycosylation of proteins) and ubiquinone (free radical scavenger). The role of the isoprenoid pathway in the pathogenesis of sarcoidosis in relation to hemispheric dominance was studied. The isoprenoid pathway-related cascade was assessed in patients with systemic sarcoidosis with pulmonary involvement. The pathway was also assessed in patients with right hemispheric, left hemispheric and bihemispheric dominance for comparison to find out the role of hemispheric dominance in the pathogenesis of sarcoidosis. In patients with sarcoidosis there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in the cholesterol:phospholipid ratio and a reduction in the glycoconjugate level of red blood cell (RBC) membrane in this group of patients. The same biochemical patterns were obtained in individuals with right hemispheric dominance. In individuals with left hemispheric dominance the patterns were reversed. Endogenous digoxin, by activating the calcineurin signal transduction pathway of T cells, can contribute to immune activation in sarcoidosis. An altered glycoconjugate metabolism can lead to the generation of endogenous self-glycoprotein antigens in the lung as well as other tissues. Increased free radical generation can also lead to immune activation. The role of a dysfunctional isoprenoid pathway and endogenous digoxin in the pathogenesis of sarcoidosis in relation to right hemispheric chemical dominance is discussed. All the patients with sarcoidosis were right-handed/left hemispheric dominant according to the dichotic listening test, but their biochemical patterns

Forging School-Scientist Partnerships: A Case of Easier Said than Done?

Science.gov (United States)

Falloon, Garry

2013-12-01

Since the early 1980s, a number of initiatives have been undertaken worldwide which have involved scientists and teachers working together in projects designed to support the science learning of students. Many of these have attempted to establish school-scientist partnerships. In these, scientists, teachers, and students formed teams engaged in mutually beneficial science-based activities founded on principles such as equal recognition and input, and shared vision, responsibility and risk. This article uses two partnership programmes run by a New Zealand Science Research Institute, to illustrate the challenges faced by scientists and teachers as they attempted to forge meaningful and effective partnerships. It argues that achieving the theorised position of a shared partnership space at the intersection of the worlds of scientists and teachers is problematic, and that scientists must instead be prepared to penetrate deeply into the world of the classroom when undertaking any such interactions. Findings indicate epistemological differences, curriculum and school systems and issues, and teacher efficacy and science knowledge significantly affect the process of partnership formation. Furthermore, it is argued that a re-thinking of partnerships is needed to reflect present economic and education environments, which are very different to those in which they were originally conceived nearly 30 years ago. It suggests that technology has an important role to play in future partnership interactions.

Factors Influencing Right Hemisphere Engagement During Metaphor Comprehension

Science.gov (United States)

Diaz, Michele T.; Eppes, Anna

2018-01-01

Although the left hemisphere is critical for language, clinical, behavioral, and neuroimaging research suggest that the right hemisphere also contributes to language comprehension. In particular, research has suggested that figurative language may be one type of language that preferentially engages right hemisphere regions. However, there is disagreement about whether these regions within the right hemisphere are sensitive to figurative language per se or to other factors that co-vary with figurativeness. In this article, we will review the neuroimaging literature on figurative language processing, focusing on metaphors, within the context of several theoretical perspectives that have been proposed about hemispheric function in language. Then we will examine three factors that may influence right hemisphere engagement: novelty, task difficulty, and context. We propose that factors that increase integration demands drive right hemisphere involvement in language processing, and that such recruitment is not limited to figurative language. PMID:29643825

The long-term hemispheric variation of the flare index is investigated. It is found that, (1) the phase difference of the flare index between the northern and southern hemispheres is about 6–7 months, which is near the time delay between flare activity and sunspot activity; (2) both the dominant and phase-leading hemisphere of the flare index is the northern hemisphere in the considered time interval, implying that the hemispheric asynchrony of solar activity has a close connection with the N-S asymmetry of solar activity.

Aspects of Equality in Mandatory Partnerships – From the Perspective of Municipal Care in Norway

Science.gov (United States)

Ljunggren, Birgitte

2016-01-01

Introduction: This paper raises questions about equality in partnerships, since imbalance in partnerships may effect collaboration outcomes in integrated care. We address aspects of equality in mandatory, public-public partnerships, from the perspective of municipal care. We have developed a questionnaire wherein the Norwegian Coordination Reform is an illustrative example. The following research question is addressed: What equality dimensions are important for municipals related to mandatory partnerships with hospitals? Theory/methods: Since we did not find any instrument to measure equality in partnerships, an explorative design was chosen. The development of the instrument was based on the theory on partnership and knowledge about the field and context. A national online survey was emitted to all 429 Norwegian municipalities in 2013. The response rate was in total 58 percent (n = 248). The data were mainly analysed using Principal component analysis. Results: It seems that the two dimensions “learning and expertise equality” and “contractual equality” collects reliable and valid data to measure aspects of equality in partnerships. Discussion: Partnerships are usually based on voluntarism. The results indicate that mandatory partnerships, within a public health care system, can be appropriate to equalize partnerships between health care providers at different care levels.

2003-04-01

The isoprenoid path way produces endogenous digoxin, a substance that can regulate neurotransmitter and amino acid transport. Digoxin synthesis and neurotransmitter patterns were assessed in individuals with chronic insomnia. The patterns were compared in those with right hemispheric and left hemispheric dominance. The activity of HMG GoA reductase and serum levels of digoxin, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in individuals with chronic insomnia and in individuals with differing hemispheric dominance. Digoxin synthesis was increased with upregulated tryptophan catabolism (increased levels of serotonin, strychnine, and nicotine), and downregulated tyrosine catabolism (decreased levels of dopamine, noradrenaline, and morphine) in those with chronic insomnia and right hemispheric chemical dominance. Digoxin synthesis was reduced with downregulated tryptophan catabolism (decreased levels of serotonin, strychnine, and nicotine) and upregulated tyrosine catabolism (increased levels of dopamine, noradrenaline, and morphine) in those with normal sleep patterns and left hemispheric chemical dominance. Hypothalamic digoxin plays a central role in the regulation of sleep behavior. Hemispheric chemical dominance in relation to digoxin status is also crucial.

Hypothalamic digoxin, hemispheric chemical dominance, and spirituality.

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-03-01

The isoprenoid pathway was assessed in atheistic and spiritually inclined individuals. The pathway was also assessed in individuals with differing hemispheric dominance to assess whether hemispheric dominance has a correlation with spiritual and atheistic tendency. HMG CoA reductase activity, serum digoxin, RBC membrane Na(+)-K+ ATPase activity, serum magnesium, and tyrosine/tryptophan catabolic patterns were assessed in spiritual/atheistic individuals and in those differing hemispheric dominance. In spiritually-inclined individuals, there was increased digoxin synthesis, decreased membrane Na(+)-K+ ATPase activity, increased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and decreased tyrosine catabolites (dopamine, noradrenaline, and morphine). The pattern in spiritually-inclined individuals correlated with right hemispheric chemical dominance. In atheistic individuals there was decreased digoxin synthesis, increased membrane Na(+)-K+ ATPase activity, decreased tryptophan catabolities (serotonin, quinolinic acid, and nicotine), and increased tyrosine catabolites (dopamine, noradrenaline, and morphine). This pattern in atheistic individuals correlated with that obtained in left hemispheric chemical dominance. Hemispheric chemical dominance and hypothalamic digoxin could regulate the predisposition to spirituality or atheism.

Southeast Regional Carbon Sequestration Partnership (SECARB)

2005-09-30

The Southeast Regional Carbon Sequestration Partnership (SECARB) is a diverse partnership covering eleven states involving the Southern States Energy Board (SSEB) an interstate compact; regulatory agencies and/or geological surveys from member states; the Electric Power Research Institute (EPRI); academic institutions; a Native American enterprise; and multiple entities from the private sector. Figure 1 shows the team structure for the partnership. In addition to the Technical Team, the Technology Coalition, an alliance of auxiliary participants, in the project lends yet more strength and support to the project. The Technology Coalition, with its diverse representation of various sectors, is integral to the technical information transfer, outreach, and public perception activities of the partnership. The Technology Coalition members, shown in Figure 2, also provide a breadth of knowledge and capabilities in the multiplicity of technologies needed to assure a successful outcome to the project and serve as an extremely important asset to the partnership. The eleven states comprising the multi-state region are: Alabama; Arkansas; Florida; Georgia; Louisiana; Mississippi; North Carolina; South Carolina; Tennessee; Texas; and Virginia. The states making up the SECARB area are illustrated in Figure 3. The primary objectives of the SECARB project include: (1) Supporting the U.S. Department of Energy (DOE) Carbon Sequestration Program by promoting the development of a framework and infrastructure necessary for the validation and deployment of carbon sequestration technologies. This requires the development of relevant data to reduce the uncertainties and risks that are barriers to sequestration, especially for geologic storage in the SECARB region. Information and knowledge are the keys to establishing a regional carbon dioxide (CO{sub 2}) storage industry with public acceptance. (2) Supporting the President's Global Climate Change Initiative with the goal of reducing

Hemispheric specialization in dogs for processing different acoustic stimuli.

Directory of Open Access Journals (Sweden)

Marcello Siniscalchi

Full Text Available Considerable experimental evidence shows that functional cerebral asymmetries are widespread in animals. Activity of the right cerebral hemisphere has been associated with responses to novel stimuli and the expression of intense emotions, such as aggression, escape behaviour and fear. The left hemisphere uses learned patterns and responds to familiar stimuli. Although such lateralization has been studied mainly for visual responses, there is evidence in primates that auditory perception is lateralized and that vocal communication depends on differential processing by the hemispheres. The aim of the present work was to investigate whether dogs use different hemispheres to process different acoustic stimuli by presenting them with playbacks of a thunderstorm and their species-typical vocalizations. The results revealed that dogs usually process their species-typical vocalizations using the left hemisphere and the thunderstorm sounds using the right hemisphere. Nevertheless, conspecific vocalizations are not always processed by the left hemisphere, since the right hemisphere is used for processing vocalizations when they elicit intense emotion, including fear. These findings suggest that the specialisation of the left hemisphere for intraspecific communication is more ancient that previously thought, and so is specialisation of the right hemisphere for intense emotions.

A pedagogical framework for facilitating parents' learning in nurse-parent partnership.

Hopwood, Nick; Clerke, Teena; Nguyen, Anne

2018-04-01

Nursing work increasingly demands forms of expertise that complement specialist knowledge. In child and family nursing, this need arises when nurses work in partnership with parents of young children at risk. Partnership means working with parents in respectful, negotiated and empowering ways. Existing partnership literature emphasises communicative and relational skills, but this paper focuses on nurses' capacities to facilitate parents' learning. Referring to data from home visiting, day-stay and specialist toddler clinic services in Sydney, a pedagogical framework is presented. Analysis shows how nurses notice aspects of children, parents and parent-child interactions as a catalyst for building on parents' strengths, enhancing guided chance or challenging unhelpful constructs. Prior research shows the latter can be a sticking point in partnership, but this paper reveals diverse ways in which challenges are folded into learning process that position parents as agents of positive change. Noticing is dependent on embodied and communicative expertise, conceptualised in terms of sensory and reported channels. The framework offers a new view of partnership as mind-expanding for the parent and specifies the nurse's role in facilitating this process. © 2017 John Wiley & Sons Ltd.

Using a partnership between academic faculty and a physical therapist liaison to develop a framework for an evidence-based journal club: a discussion.

Austin, Tricia M; Richter, Randy R; Frese, Tracy

2009-12-01

Evidence-based practice (EBP) in rehabilitation is increasingly recognized as important. Despite the importance of EBP, physical therapists' knowledge of EBP varies. Journal clubs have been used to educate clinicians about EBP. This discussion paper describes the partnership between academic faculty members and a physical therapist at a community hospital, and the process used to develop a framework to implement an evidence-based journal club. The partnership blended the expertise of academic faculty members and a physical therapist with knowledge of EBP who served as the liaison between members of the partnership team and the clinicians at the community hospital. The three-step framework developed enabled the clinicians to learn about critical appraisal, participate in guided practice of critical appraisal with the liaison, and lead critical appraisal of a paper with the assistance of the liaison as needed. This process could be easily replicated by other partnerships between academic faculty members and clinicians. Developing partnerships like the one described enables academicians to provide service to the profession, may enhance physical therapists' knowledge of the principles of EBP and may encourage EBP.

Institutional Health Partnerships are long-term, institution to institution partnerships between high income and low and middle income countries which seek to build capacity and strengthen health institutions in order to improve health service delivery and outcomes. Funding for Institutional Health Partnerships has increased in recent years. This paper outlines a rapid evidence review on the effectiveness of this modality. A rapid evidence review of published and grey literature was conducted. Content relating to the effectiveness of working in partnership and methods and frameworks used were extracted and analysed. The results of this analysis were used to structure a discussion regarding the next steps to strengthen the evidence base for the effectiveness of institutional health partnerships. The evidence review, including citation mapping, returned 27 published papers and 17 grey literature documents that met all of the inclusion criteria. Most of the literature did not meet the high standards of formal academic rigour and there was no original research amongst this literature that specifically addressed the effectiveness of institutional health partnerships. This was not surprising given institutional health partnerships do not lend themselves easily to case control studies and randomised control trials due to their high level of diversity and operation in complex social systems. There was, however, a body of practice based knowledge and experience. Evidence for the effectiveness of Institutional Health Partnerships is thin both in terms of quantity and academic rigour. There is a need to better define and differentiate Institutional Health Partnerships in order to measure and compare effectiveness across such a diverse group. Effectiveness needs to be measured at the level of individual partnerships, the bodies that facilitate partnership programmes and the level of health service delivery. There is a need to develop indicators and frameworks that specifically

Five years of partnership programme between German and East European nuclear power plant operators

International Nuclear Information System (INIS)

Kraemer, P.

1995-01-01

In a jointly adopted communique in August 1992 the regulations governing the partnerships were laid down. The following principles are given priority: bilateral exchange of operating experience on the basis of equal partnership; the knowledge gained from the exchange of experience is used to improve the operation and safety of the respective partner plant; the partnership programme is free from commercial interests and does not include transfer of funds. Since the establishment of the first partnership relations (Biblis) with an east european nuclear power plant (Balakowo) late in April 1990, a total of 126 reciprocal visits was paid, 82 of which to German nuclear power plants. The balance of the efforts made by German nuclear power plant operators to integrate east european nuclear plant operators can be considered positive. (orig./HP) [de

Managing partnerships and impact on decision-making: the example of health technology assessment in genetics.

Science.gov (United States)

Blancquaert, Ingeborg

2006-01-01

For an emerging field such as Public Health Genetics, the partnerships that will be developed with stakeholders are of strategic importance, since they may affect long-term impact on policy-making. A concrete example in the field of health technology assessment in genetics was chosen to illustrate how the context in which scientific advisory bodies operate and the nature of partnerships developed over time influence the impact on decision-making at different levels, from the micro (professional) level through the meso (institutional) level to the macro (policy) level. As pointed out in the knowledge transfer literature, impact is not only reflected by instrumental use of knowledge, but also by problem-framing and strategic use of knowledge. Solid partnerships at the micro level, with researchers and health care professionals, are essential to build credibility and trust, and they lay the groundwork for contextualized and relevant advice and potential impact at the policy level. Even though maintaining the necessary critical distance with respect to all stakeholders is easier for institutions that are at arm's length from government, achieving the right balance between an institution's independence and service relationship is a real challenge.

Hemispherical Resonator Gyroscope Accuracy Analysis Under Temperature Influence

Directory of Open Access Journals (Sweden)

Boran LI

2014-06-01

Full Text Available Frequency splitting of hemispherical resonator gyroscope will change as system operating temperature changes. This phenomenon leads to navigation accuracy of hemispherical resonator gyroscope reduces. By researching on hemispherical resonator gyroscope dynamical model and its frequency characteristic, the frequency splitting formula and the precession angle formula of gyroscope vibrating mode based on hemispherical resonator gyroscope dynamic equation parameters are derived. By comparison, gyroscope precession angle deviation caused by frequency splitting can be obtained. Based on analysis of temperature variation against gyroscope resonator, the design of hemispherical resonator gyroscope feedback controller under temperature variation conditions is researched and the maximum theoretical fluctuation of gyroscope dynamical is determined by using a numerical analysis example.

Hemispheric asymmetry of electroencephalography-based functional brain networks.

Jalili, Mahdi

2014-11-12

Electroencephalography (EEG)-based functional brain networks have been investigated frequently in health and disease. It has been shown that a number of graph theory metrics are disrupted in brain disorders. EEG-based brain networks are often studied in the whole-brain framework, where all the nodes are grouped into a single network. In this study, we studied the brain networks in two hemispheres and assessed whether there are any hemispheric-specific patterns in the properties of the networks. To this end, resting state closed-eyes EEGs from 44 healthy individuals were processed and the network structures were extracted separately for each hemisphere. We examined neurophysiologically meaningful graph theory metrics: global and local efficiency measures. The global efficiency did not show any hemispheric asymmetry, whereas the local connectivity showed rightward asymmetry for a range of intermediate density values for the constructed networks. Furthermore, the age of the participants showed significant direct correlations with the global efficiency of the left hemisphere, but only in the right hemisphere, with local connectivity. These results suggest that only local connectivity of EEG-based functional networks is associated with brain hemispheres.

Hemispheric resource limitations in comprehending ambiguous pictures.

White, H; Minor, S W

1990-03-01

Ambiguous pictures (Roschach inkblots) were lateralized for 100 msec vs. 200 msec to the right and left hemispheres (RH and LH) of 32 normal right-handed males who determined which of two previously presented words (an accurate or inaccurate one) better described the inkblot. Over the first 32 trials, subjects receiving each stimulus exposure duration were less accurate when the hemisphere receiving the stimulus also controlled the hand used to register a keypress response (RH-left hand and LH-right hand trials) than when hemispheric resources were shared, i.e., when one hemisphere controlled stimulus processing and the other controlled response programming. These differences were eliminated when the 32 trials were repeated.

Southwest Regional Partnership on Carbon Sequestration

The Southwest Partnership on Carbon Sequestration completed its Phase I program in December 2005. The main objective of the Southwest Partnership Phase I project was to evaluate and demonstrate the means for achieving an 18% reduction in carbon intensity by 2012. Many other goals were accomplished on the way to this objective, including (1) analysis of CO{sub 2} storage options in the region, including characterization of storage capacities and transportation options, (2) analysis and summary of CO{sub 2} sources, (3) analysis and summary of CO{sub 2} separation and capture technologies employed in the region, (4) evaluation and ranking of the most appropriate sequestration technologies for capture and storage of CO{sub 2} in the Southwest Region, (5) dissemination of existing regulatory/permitting requirements, and (6) assessing and initiating public knowledge and acceptance of possible sequestration approaches. Results of the Southwest Partnership's Phase I evaluation suggested that the most convenient and practical ''first opportunities'' for sequestration would lie along existing CO{sub 2} pipelines in the region. Action plans for six Phase II validation tests in the region were developed, with a portfolio that includes four geologic pilot tests distributed among Utah, New Mexico, and Texas. The Partnership will also conduct a regional terrestrial sequestration pilot program focusing on improved terrestrial MMV methods and reporting approaches specific for the Southwest region. The sixth and final validation test consists of a local-scale terrestrial pilot involving restoration of riparian lands for sequestration purposes. The validation test will use desalinated waters produced from one of the geologic pilot tests. The Southwest Regional Partnership comprises a large, diverse group of expert organizations and individuals specializing in carbon sequestration science and engineering, as well as public policy and outreach.

2014-09-01

The study on structural brain asymmetries in healthy individuals plays an important role in our understanding of the factors that modulate cognitive specialization in the brain. Here, we used fiber tractography to reconstruct the left and right hemispheric networks of a large cohort of 346 healthy participants (20-86 years) and performed a graph theoretical analysis to investigate this brain laterality from a network perspective. Findings revealed that the left hemisphere is significantly more "efficient" than the right hemisphere, whereas the right hemisphere showed higher values of "betweenness centrality" and "small-worldness." In particular, left-hemispheric networks displayed increased nodal efficiency in brain regions related to language and motor actions, whereas the right hemisphere showed an increase in nodal efficiency in brain regions involved in memory and visuospatial attention. In addition, we found that hemispheric networks decrease in efficiency with age. Finally, we observed significant gender differences in measures of global connectivity. By analyzing the structural hemispheric brain networks, we have provided new insights into understanding the neuroanatomical basis of lateralized brain functions.

Atoms for food - A global partnership

International Nuclear Information System (INIS)

Wedekind, L.

2008-10-01

The International Atomic Energy Agency (IAEA) and Food and Agriculture Organization of the United Nations (FAO) have been partners for nearly half a century, contributing to efforts toward shared goals of food security. Their mission - through a Joint Division headquartered at the IAEA in Austria - is to help countries effectively use nuclear science and related technologies for food and agricultural development. Millions of people today look to a better future because of the foresight and longstanding investment of FAO and IAEA Member States in the 'Atoms for Food' partnership. Worldwide, more than 100 countries are working together through the Joint Division to increase their harvests, combat animal and plant diseases and pests, and protect the lands, water resources, and environments on which food and agricultural production depend. This century's stark realities of hunger, poverty, climate change, and environmental degradation bring an unprecedented scale of challenges to the fields of food and agriculture. Action requires the research, expertise, and experience of the FAO/IAEA partnership and other effective alliances worldwide to help countries achieve and sustain higher levels of food security for their people. The two organizations are well matched. FAO brings to the table its comprehensive knowledge and networks on food and agriculture. The IAEA, in turn, contributes technical know-how, specifically in agricultural and related applications of nuclear science and technology. The partnership's potential builds on decades of experience

Right-hemispheric processing of non-linguistic word features

-hemispheric homologues of classic left-hemispheric language areas may partly be due to processing nonlinguistic perceptual features of verbal stimuli. We used functional MRI (fMRI) to clarify the role of the right hemisphere in the perception of nonlinguistic word features in healthy individuals. Participants made...... perceptual, semantic, or phonological decisions on the same set of auditorily and visually presented word stimuli. Perceptual decisions required judgements about stimulus-inherent changes in font size (visual modality) or fundamental frequency contour (auditory modality). The semantic judgement required......, the right inferior frontal gyrus (IFG), an area previously suggested to support language recovery after left-hemispheric stroke, displayed modality-independent activation during perceptual processing of word stimuli. Our findings indicate that activation of the right hemisphere during language tasks may...

In 2004, the Responsive Neutron Generator Product Deployment department embarked upon a partnership with the Systems Engineering and Analysis knowledge management (KM) team to develop knowledge management systems for the neutron generator (NG) community. This partnership continues today. The most recent challenge was to improve the current KM system (KMS) development approach by identifying a process that will allow staff members to capture knowledge as they learn it. This 'as-you-go' approach will lead to a sustainable KM process for the NG community. This paper presents a historical overview of NG KMSs, as well as research conducted to move toward sustainable KM.

2017-06-01

This review provides background on the formation of the Partnership for a Healthier America (PHA), that was created in conjunction with the Let's Move! initiative, and an overview of its work to date. To encourage industry to offer and promote healthier options, PHA partners with the private sector. Principles that guide PHA partnerships include ensuring that partnerships represent meaningful change, partners sign a legally binding contract and progress is monitored and publicly reported. Since 2010, PHA has established private sector partnerships in an effort to transform the marketplace to ensure that every child has the chance to grow up at a healthy weight. Many agreements between PHA and its industry partners align with the White House Task Force Report on Childhood Obesity. The reach and impact of over 200 partnerships attest to the success of this initiative.

Hypothalamic digoxin, hemispheric chemical dominance, and creativity.

Science.gov (United States)

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-04-01

The human hypothalamus produces an endogenous membrane Na(+)-K+ ATPase inhibitor, digoxin, which regulates neuronal transmission. The digoxin status and neurotransmitter patterns were studied in creative and non-creative individuals, as well as in individuals with differing hemispheric dominance, in order to find out the role of cerebral dominance in this respect. The activity of HMG CoA reductase and serum levels of digoxin, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in creative/non-creative individuals, and in individuals with differing hemispheric dominance. In creative individuals there was increased digoxin synthesis, decreased membrane Na(+)-K+ ATPase activity, increased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and decreased tyrosine catabolites (dopamine, noradrenaline, and morphine). The pattern in creative individuals correlated with right hemispheric dominance. In non-creative individuals there was decreased digoxin synthesis, increased membrane Na(+)-K+ ATPase activity, decreased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and increased tyrosine catabolites (dopamine, noradrenaline, and morphine). This pattern in non-creative individuals correlated with that obtained in left hemispheric chemical dominance. Hemispheric chemical dominance and hypothalamic digoxin could regulate the predisposition to creative tendency.

Enhanced activation of the left hemisphere promotes normative decision making.

Science.gov (United States)

Corser, Ryan; Jasper, John D

2014-01-01

Previous studies have reported that enhanced activation of the left cerebral hemisphere reduces risky-choice, attribute, and goal-framing effects relative to enhanced activation of the right cerebral hemisphere. The present study sought to extend these findings and show that enhanced activation of the left hemisphere also reduces violations of other normative principles, besides the invariance principle. Participants completed ratio bias (Experiment 1, N = 296) and base rate neglect problems (Experiment 2, N = 145) under normal (control) viewing or with the right or left hemisphere primarily activated by imposing a unidirectional gaze. In Experiment 1 we found that enhanced left hemispheric activation reduced the ratio bias relative to normal viewing and a group experiencing enhanced right hemispheric activation. In Experiment 2 enhanced left hemispheric activation resulted in using base rates more than normal viewing, but not significantly more than enhanced right hemispheric activation. Results suggest that hemispheric asymmetries can affect higher-order cognitive processes, such as decision-making biases. Possible theoretical accounts are discussed as well as implications for dual-process theories.

What progress prevention research has made comes through strategic partnerships with communities and institutions that host this research, as well as professional and practice networks that facilitate the diffusion of knowledge about prevention. We discuss partnership issues related to the design, analysis, and implementation of prevention research and especially how rigorous designs, including random assignment, get resolved through a partnership between community stakeholders, institutions, and researchers. These partnerships shape not only study design, but they determine the data that can be collected and how results and new methods are disseminated. We also examine a second type of partnership to improve the implementation of effective prevention programs into practice. We draw on social networks to studying partnership formation and function. The experience of the Prevention Science and Methodology Group, which itself is a networked partnership between scientists and methodologists, is highlighted. PMID:22160786

National nanotechnology partnership to protect workers

Howard, John; Murashov, Vladimir

2009-10-01

Nanotechnology is predicted to improve many aspects of human life. By 2015, it is estimated to represent 3.1 trillion in manufactured goods. Data is emerging that exposure to nanomaterials may pose a health risk to workers. If the economic promise of nanotechnology is to be achieved, ways need to be found to protect nanotechnology workers now. The Occupational Safety and Health Act of 1970 (OSHAct) gave the responsibility to protect workers to the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) through research, standards adoption, and standards enforcement. Since 1980, adopting new occupational health standards has grown more complex. The increased complexity has greatly slowed efforts to adopt protective standards for toxic agents that are well-known to pose significant risks. The likelihood of rapidly adopting standards to protect workers from nanomaterials, whose risks are just emerging, seems even more unlikely. Use of the OSHAct's general duty clause to protect workers also seems uncertain at this time. In the interim, a national partnership led by NIOSH involving nanotech manufacturers and downstream users, workers, academic researchers, safety, and health practitioners is proposed. A National Nanotechnology Partnership would generate knowledge about the nature and the extent of worker risk, utilize that knowledge to develop risk control strategies to protect nanotechnology workers now, and provide an evidence base for NIOSH recommendations to OSHA for a nanotechnology program standard at a future date.

Knowledge about Sounds – Context-Specific Meaning Differently Activates Cortical Hemispheres, Auditory Cortical Fields and Layers in House Mice

Directory of Open Access Journals (Sweden)

Diana B. Geissler

2016-03-01

Full Text Available Activation of the auditory cortex (AC by a given sound pattern is plastic, depending, in largely unknown ways, on the physiological state and the behavioral context of the receiving animal and on the receiver's experience with the sounds. Such plasticity can be inferred when house mouse mothers respond maternally to pup ultrasounds right after parturition and naïve females have to learn to respond. Here we use c-FOS immunocytochemistry to quantify highly activated neurons in the AC fields and layers of seven groups of mothers and naïve females who have different knowledge about and are differently motivated to respond to acoustic models of pup ultrasounds of different behavioral significance. Profiles of FOS-positive cells in the AC primary fields (AI, AAF, the ultrasonic field (UF, the secondary field (AII, and the dorsoposterior field (DP suggest that activation reflects in AI, AAF, and UF the integration of sound properties with animal state-dependent factors, in the higher-order field AII the news value of a given sound in the behavioral context, and in the higher-order field DP the level of maternal motivation and, by left-hemisphere activation advantage, the recognition of the meaning of sounds in the given context. Anesthesia reduced activation in all fields, especially in cortical layers 2/3. Thus, plasticity in the AC is field-specific preparing different output of AC fields in the process of perception, recognition and responding to communication sounds. Further, the activation profiles of the auditory cortical fields suggest the differentiation between brains hormonally primed to know (mothers and brains which acquired knowledge via implicit learning (naïve females. In this way, auditory cortical activation discriminates between instinctive (mothers and learned (naïve females cognition.

Delusions are beliefs that remain fixed despite evidence that they are incorrect. Although the precise neural mechanism of delusional belief remains to be elucidated, there is a predominance of right-hemisphere lesions among patients with delusional syndromes accompanied by structural pathology, suggesting that right-hemisphere lesions, or networks with key nodes in the right hemisphere, may be playing a role. The authors discuss the potential theoretical basis and empiric support for a specific right-hemisphere role in delusion production, drawing on its roles in pragmatic communication; perceptual integration; attentional surveillance and anomaly/novelty detection; and belief updating.

Effect of Knowledge Sharing on Success of IT Outsourcing

فرج‌اله رهنورد

2009-02-01

Full Text Available Nowadays, Outsourcing relationship in the area of information technology for local organizations is not an option, but a necessity strategy. By outsourcing, organizations can focus on core functions, decrease their operational costs and technology risk, and to use external sources to achieve the organizational objectives. In this research, local organizations in Zanjan province which have outsourcing experience in the area of information technology, were selected as statistical population, to study the effect of knowledge sharing based on outsourcing with regards to contingency approach. Findings of this research showed that knowledge sharing with regards to situational variables, leads to influence success of IT outsourcing. To put it in other words, relationship between knowledge sharing as independent variable and success of IT outsourcing as a dependent variable, is influenced by partnership and organizational capabilities. Therefore, IT outsourcing is a successful strategy if partners through partnership to share their organizational knowledge and by enhancing their organizational capabilities to use the transferred knowledge in an effective way.

Hemispheric asymmetry and theory of mind: is there an association?

Herzig, Daniela A; Sullivan, Sarah; Evans, Jonathan; Corcoran, Rhiannon; Mohr, Christine

2012-01-01

In autism and schizophrenia attenuated/atypical functional hemispheric asymmetry and theory of mind impairments have been reported, suggesting common underlying neuroscientific correlates. We here investigated whether impaired theory of mind performance is associated with attenuated/atypical hemispheric asymmetry. An association may explain the co-occurrence of both dysfunctions in psychiatric populations. Healthy participants (n=129) performed a left hemisphere (lateralised lexical decision task) and right hemisphere (lateralised face decision task) dominant task as well as a visual cartoon task to assess theory of mind performance. Linear regression analyses revealed inconsistent associations between theory of mind performance and functional hemisphere asymmetry: enhanced theory of mind performance was only associated with (1) faster right hemisphere language processing, and (2) reduced right hemisphere dominance for face processing (men only). The majority of non-significant findings suggest that theory of mind and functional hemispheric asymmetry are unrelated. Instead of "overinterpreting" the two significant results, discrepancies in the previous literature relating to the problem of the theory of mind concept, the variety of tasks, and the lack of normative data are discussed. We also suggest how future studies could explore a possible link between hemispheric asymmetry and theory of mind.

Limited restoration of function is known to occur spontaneously after an ischemic injury to the primary motor cortex. Evidence suggests that Pre-Motor Areas (PMAs) may "take over" control of the disrupted functions. However, little is known about functional reorganizations in PMAs. Forelimb movements in mice can be driven by two cortical regions, Caudal and Rostral Forelimb Areas (CFA and RFA), generally accepted as primary motor and pre-motor cortex, respectively. Here, we examined longitudinal changes in functional coupling between the two RFAs following unilateral photothrombotic stroke in CFA (mm from Bregma: +0.5 anterior, +1.25 lateral). Local field potentials (LFPs) were recorded from the RFAs of both hemispheres in freely moving injured and naïve mice. Neural signals were acquired at 9, 16 and 23 days after surgery (sub-acute period in stroke animals) through one bipolar electrode per hemisphere placed in the center of RFA, with a ground screw over the occipital bone. LFPs were pre-processed through an efficient method of artifact removal and analysed through: spectral,cross-correlation, mutual information and Granger causality analysis. Spectral analysis demonstrated an early decrease (day 9) in the alpha band power in both the RFAs. In the late sub-acute period (days 16 and 23), inter-hemispheric functional coupling was reduced in ischemic animals, as shown by a decrease in the cross-correlation and mutual information measures. Within the gamma and delta bands, correlation measures were already reduced at day 9. Granger analysis, used as a measure of the symmetry of the inter-hemispheric causal connectivity, showed a less balanced activity in the two RFAs after stroke, with more frequent oscillations of hemispheric dominance. These results indicate robust electrophysiological changes in PMAs after stroke. Specifically, we found alterations in transcallosal connectivity, with reduced inter-hemispheric functional coupling and a fluctuating dominance

Model Youth Programs: A Key Strategy for Developing Community-University Partnerships Using a Community Youth Development Approach

Directory of Open Access Journals (Sweden)

Yolanda Anyon

2008-06-01

Full Text Available Universities across the nation face the charge of enhancing their intellectual capital as a learning institution while also contributing to the greater social good. While there is great potential for university-community partnerships to generate lessons for youth workers and policy makers, create powerful new knowledge for the academic field, and provide transformative experiences for community members, partnerships often fail to produce such meaningful results. In the San Francisco Bay Area, community residents who have been involved in such unsuccessful initiatives frequently perceived that university partners spent insufficient time learning about the community context, prioritized research objectives over community needs and did not make long-term commitments. Despite these challenges, community-university partnerships can be useful strategies for advancing the field of youth development by strengthening research and practice in local contexts. This paper presents how the design and implementation of model youth programs served as an effective strategy in developing a partnership between a university-based center and two local communities over a 5-year period. It also describes essential lessons that other communities, research institutions or universities may use to launch, implement, expand and sustain their own successful partnerships to build local capacity to implement youth development practices, promote positive outcomes for young people, and generate knowledge about the impact of youth development approaches.

Reorganization of syntactic processing following left-hemisphere brain damage: does right-hemisphere activity preserve function?

2010-01-01

The extent to which the human brain shows evidence of functional plasticity across the lifespan has been addressed in the context of pathological brain changes and, more recently, of the changes that take place during healthy ageing. Here we examine the potential for plasticity by asking whether a strongly left-lateralized system can successfully reorganize to the right-hemisphere following left-hemisphere brain damage. To do this, we focus on syntax, a key linguistic function considered to b...

As globalization progressively connects and impacts the health of people across the world, collaborative research partnerships provide mutual advantages by sharing knowledge and resources to address locally and globally relevant scientific and public health questions. Partnerships undertaken for scientific research are similar to business collaborations in that they require attention to partner systems, whether local, international, political, academic, or non-academic. Scientists, like diplomats or entrepreneurs, are representatives of their field, culture, and country and become obligatory agents in health diplomacy. This role significantly influences current and future collaborations with not only the immediate partner but with other in country partners as well. Research partnerships need continuous evaluation of the collaboration's productivity, perspectives of all partners, and desired outcomes for success to avoid engaging in "research tourism", particularly in developing regions. International engagement is a cornerstone in addressing the impact of infectious diseases globally. Global partnerships are strategically aligned with national, partner and global health priorities and may be based on specific requests for assistance from the partnering country governments. Here we share experiences from select research collaborations to highlight principles that we have found key in building long-term relationships with collaborators and in meeting the aim to address scientific questions relevant to the host country and strategic global health initiatives.

A dual task priming investigation of right hemisphere inhibition for people with left hemisphere lesions

Directory of Open Access Journals (Sweden)

Smith-Conway Erin R

2012-03-01

Full Text Available Abstract Background During normal semantic processing, the left hemisphere (LH is suggested to restrict right hemisphere (RH performance via interhemispheric suppression. However, a lesion in the LH or the use of concurrent tasks to overload the LH's attentional resource balance has been reported to result in RH disinhibition with subsequent improvements in RH performance. The current study examines variations in RH semantic processing in the context of unilateral LH lesions and the manipulation of the interhemispheric processing resource balance, in order to explore the relevance of RH disinhibition to hemispheric contributions to semantic processing following a unilateral LH lesion. Methods RH disinhibition was examined for nine participants with a single LH lesion and 13 matched controls using the dual task paradigm. Hemispheric performance on a divided visual field lexical decision semantic priming task was compared over three verbal memory load conditions, of zero-, two- and six-words. Related stimuli consisted of categorically related, associatively related, and categorically and associatively related prime-target pairs. Response time and accuracy data were recorded and analyzed using linear mixed model analysis, and planned contrasts were performed to compare priming effects in both visual fields, for each of the memory load conditions. Results Control participants exhibited significant bilateral visual field priming for all related conditions (p Conclusions The results from the control group are consistent with suggestions of an age related hemispheric asymmetry reduction and indicate that in healthy aging compensatory bilateral activation may reduce the impact of inhibition. In comparison, the results for the LHD group indicate that following a LH lesion RH semantic processing can be manipulated and enhanced by the introduction of a verbal memory task designed to engage LH resources and allow disinhibition of RH processing.

2004-01-01

A PET activation study was designed to investigate hemispheric specialization during speech comprehension and production in right- and left-handed subjects. Normalized regional cerebral blood flow (NrCBF) was repeatedly monitored while subjects either listened to factual stories (Story) or covertly generated verbs semantically related to heard nouns (Gener), using silent resting (Rest) as a common control condition. NrCBF variations in each task, as compared to Rest, as well as functional asymmetry indices (FAI = right minus left NrCBF variations), were computed in anatomical regions of interest (AROIs) defined on the single-subject MNI template. FAIs were predominantly leftward in all regions during both tasks, although larger FAIs were observed during Gener. Subjects were declared "typical" for language hemispheric specialization based on the presence of significant leftward asymmetries (FAI Gener, and in the middle and inferior temporal AROIs during Story. Six subjects (including five LH) showed an atypical language representation. Among them, one presented a right hemisphere specialization during both tasks, another a shift in hemispheric specialization from production to comprehension (left during Gener, right during Story). The group of 14 typical subjects showed significant positive correlation between homologous left and right AROIs NrCBF variations in temporal areas during Story, and in temporal and inferior frontal areas during Gener, almost all regions presenting a leftward FAI. Such correlations were also present in deactivated areas with strong leftward asymmetry (supramarginalis gyrus, inferior parietal region). These results suggest that entry into a language task translates into a hemispheric reconfiguration of lateral cortical areas with global NrCBF increase in the dominant hemisphere and decrease in the minor hemisphere. This can be considered as the setting up of a "language mode", under the control of a mechanism that operates at a perisylvian

Discourse skills - in which the right hemisphere has an important role - enables verbal communication by selecting contextually relevant information and integrating it coherently to infer the correct meaning. However, language research in epilepsy has focused on single word analysis related mainly to left hemisphere processing. The purpose of this study was to investigate discourse abilities in patients with right lateralized medial temporal lobe epilepsy (RTLE) by comparing their performance to that of patients with left temporal lobe epilepsy (LTLE). 74 pharmacoresistant temporal lobe epilepsy (TLE) patients were evaluated: 34 with RTLE and 40 with LTLE. Subjects underwent a battery of tests that measure comprehension and production of conversational and narrative discourse. Disease related variables and general neuropsychological data were evaluated. The RTLE group presented deficits in interictal conversational and narrative discourse, with a disintegrated speech, lack of categorization and misinterpretation of social meaning. LTLE group, on the other hand, showed a tendency to lower performance in logical-temporal sequencing. RTLE patients showed discourse deficits which have been described in right hemisphere damaged patients due to other etiologies. Medial and anterior temporal lobe structures appear to link semantic, world knowledge, and social cognition associated areas to construct a contextually related coherent meaning.

Bernard, Florian; Lemée, Jean-Michel; Ter Minassian, Aram; Menei, Philippe

2018-05-12

The nondominant hemisphere (usually the right) is responsible for primary cognitive functions such as visuospatial and social cognition. Awake surgery using direct electric stimulation for right cerebral tumor removal remains challenging because of the complexity of the functional anatomy and difficulties in adapting standard bedside tasks to awake surgery conditions. An understanding of semiology and anatomic bases, along with an analysis of the available cognitive tasks for visuospatial and social cognition per operative mapping allow neurosurgeons to better appreciate the functional anatomy of the right hemisphere and its relevance to tumor surgery. In this article, the first of a 2-part review, we discuss the anatomic and functional basis of right hemisphere function. Whereas part II of the review focuses primarily on semiology and surgical management of right-sided tumors under awake conditions, this article provides a comprehensive review of knowledge underpinning awake surgery on the right hemisphere.

2015-03-01

There is limited research surrounding academic partnerships and more research is needed to educate universities, and the private, public and third sectors about the benefits and limitations of such partnerships. The aim of this study was to outline the unique partnership between Macmillan Cancer Support and De Montfort University and to evaluate the progress of this partnership. A qualitative approach was employed which involved interviews with nine members of the partnership's steering group. Interviews were transcribed and analysed using thematic analysis. The results showed that a partnership between a university and a third sector charity can have mutual benefits for all those involved, particularly for students and those affected by cancer. Furthermore, the module to develop volunteering among families affected cancer, created through this partnership is now being considered by other universities as a way of providing holistic and non-traditional lecture based learning experiences. Recommendations are made for future partnerships between third sector charities and universities. Copyright © 2014 Elsevier Ltd. All rights reserved.

Radioactive fallout in the southern hemisphere from nuclear weapons tests

Moroney, J.R.

1979-11-01

Fallout in the southern hemisphere, and its origins in the national programs of atmospheric nuclear weapons testing in both hemispheres, are reviewed. Of the 390 nuclear tests conducted in the atmosphere to date, 53 were carried out in the southern hemisphere and it is the second phase of these, between 1966 and 1974, that is seen to have been responsible for the main fallout of short-lived fission products in the southern hemisphere. In contrast to this, the programs of atmospheric nuclear testing in the northern hemisphere up to 1962 are shown to have been the main source of long-lived fission products in fallout in the southern hemisphere. The course followed by this contamination through the environment of the southern hemisphere is traced for the national programs of nuclear testing after 1962 taken separately (France, China) and for the earlier national programs taken together (U.S.S.R., U.S.A. and U.K.). The impact on populations in the southern hemisphere of fallout from atmospheric nuclear weapons tests to date is assessed

Full Text Available Background: The KwaZulu-Natal Sandstone Sourveld (KZNSS Research Programme is part of a collaborative, transdisciplinary research partnership between the University of KwaZulu-Natal and the eThekwini Municipality (EM, aimed at bridging the science-policy-practice gap. The research programme focuses on generating knowledge and capacity to support local land-use planning, management and policy development related to biodiversity and climate change issues. Objectives: The objectives were (1 to describe how a continuous reflective evaluation approach helped to better understand the research programme and its outcomes; and (2 to assess research outputs and outcomes, relevance of outcomes to the requirements of EM, and participants’ perceptions of the programme (both the outcomes and the process. Methods: The evaluation took a mixed methods approach, combining various quantitative and qualitative methods such as anonymous individual questionnaires, reflective exercises and group reflections. Results: The KZNSS programme was successful in capacity building and establishing a long-term partnership, but had lower scientific publication output and practice uptake than expected. Participants’ perceptions changed over time, with a decrease in the perceived success of addressing tangible research outcomes, and an increase in the perceived success of collaborative relationships in the partnership. Conclusion: Transdisciplinary partnerships can be a means of integrating research into policy and practice through knowledge exchange. An important lesson in the early stages of this partnership was to pay attention to the process and not only the outputs. The study highlights the importance of continuous participatory reflection and evaluation in such partnerships.

Kurup, Ravi Kumar; Kurup, Paramesware Achutha

2003-12-01

The role of the isoprenoid pathway in vascular thrombosis, especially mesenteric artery occlusion and its relation to hemispheric dominance, was assessed in this study. The following parameters were measured in patients with mesenteric artery occlusion and individuals with right hemispheric, left hemispheric, and bihemispheric dominance: (1) plasma HMG CoA reductase, digoxin, dolichol, ubiquinone, and magnesium levels; (2) tryptophan/tyrosine catabolic patterns; (3) free radical metabolism; (4) glycoconjugate metabolism; and (5) membrane composition. In patients with mesenteric artery occlusion there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, low ubiquinone, and elevated free radical levels. The RBC membrane Na(+)-K+ ATPase activity and serum magnesium were decreased. There was also an increase in tryptophan catabolites and reduction in tyrosine catabolites in the serum. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in these patients. The biochemical patterns obtained in mesenteric artery occlusion is similar to those obtained in left-handed/right hemispheric dominant individuals by the dichotic listening test. But all the patients with mesenteric artery occlusion were right-handed/left hemispheric dominant by the dichotic listening test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Mesenteric artery occlusion occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function. Hemispheric chemical dominance may thus control the risk for developing vascular thrombosis in individuals.

Hypothalamic digoxin, hemispheric chemical dominance, and the tridosha theory.

2003-05-01

Ayurveda, the traditional Indian System of Medicine, deals with the theory of the three tridosha states (both physical and psychological): Vata, Pitta, and Kapha. They are the three major human constitutional types that both depend on psychological and physical characteristics. The Pitta state is described as a critical, discriminative, and rational psychological state of mind, while the Kapha state is described as being dominant for emotional stimuli. The Vata state is an intermediate unstable shifting state. The Pitta types are of average height and built with well developed musculature. The Vata types are thin individuals with low body mass index. The Kapha types are short stocky individuals that tend toward obesity, and who are sedentary. The study assessed the biochemical differences between right hemispheric dominant, bihemispheric dominant, and left hemispheric dominant individuals, and then compared this with the patterns obtained in the Vata, Pitta, and Kapha states. The isoprenoid metabolites (digoxin, dolichol, and ubiquinone), glycoconjugate metabolism, free radical metabolism, and the RBC membrane composition were studied. The hemispheric chemical dominance in various systemic diseases and psychological states was also investigated. The results showed that right hemispheric chemically dominant/Kapha state had elevated digoxin levels, increased free radical production and reduced scavenging, increased tryptophan catabolites and reduced tyrosine catabolites, increased glycoconjugate levels and increased cholesterol: phospholipid ratio of RBC membranes. Left hemispheric chemically dominant/Pitta states had the opposite biochemical patterns. The patterns were normal or intermediate in the bihemispheric chemically dominant/Vata state. This pattern could be correlated with various systemic and neuropsychiatric diseases and personality traits. Right hemispheric chemical dominance/Kapha state represents a hyperdigoxinemic state with membrane sodium

The isoprenoid pathway produces three key metabolites--endogenous digoxin (membrane sodium-potassium ATPase inhibitor, immunomodulator, and regulator of neurotransmitter/amino acid transport), dolichol (regulates N-glycosylation of proteins), and ubiquinone (free radical scavenger). This was assessed in patients with chronic bronchitis emphysema. The pathway was also assessed in patients with right hemispheric, left hemispheric, and bihemispheric dominance to find the role of hemispheric dominance in the pathogenesis of chronic bronchitis emphysema. All the 15 patients with chronic bronchitis emphysema were right-handed/left hemispheric dominant by the dichotic listening test. In patients with chronic bronchitis emphysema there was elevated digoxin synthesis, increased dolichol, and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate levels of RBC membrane in patients with chronic bronchitis emphysema. The same biochemical patterns were obtained in individuals with right hemispheric dominance. Endogenous digoxin by activating the calcineurin signal transduction pathway of T-cell can contribute to immune activation in chronic bronchitis emphysema. Increased free radical generation can also lead to immune activation. Endogenous synthesis of nicotine can contribute to the pathogenesis of the disease. Altered glycoconjugate metabolism and membranogenesis can lead to defective lysosomal stability contributing to the disease process by increased release of lysosomal proteases. The role of an endogenous digoxin and hemispheric dominance in the pathogenesis of chronic bronchitis emphysema and in the regulation of lung structure/function is discussed. The biochemical patterns obtained in chronic bronchitis emphysema is similar to those obtained in left

The "Creative Right Brain" Revisited: Individual Creativity and Associative Priming in the Right Hemisphere Relate to Hemispheric Asymmetries in Reward Brain Function.

Science.gov (United States)

Aberg, Kristoffer Carl; Doell, Kimberly C; Schwartz, Sophie

2017-10-01

The idea that creativity resides in the right cerebral hemisphere is persistent in popular science, but has been widely frowned upon by the scientific community due to little empirical support. Yet, creativity is believed to rely on the ability to combine remote concepts into novel and useful ideas, an ability which would depend on associative processing in the right hemisphere. Moreover, associative processing is modulated by dopamine, and asymmetries in dopamine functionality between hemispheres may imbalance the expression of their implemented cognitive functions. Here, by uniting these largely disconnected concepts, we hypothesize that relatively less dopamine function in the right hemisphere boosts creativity by releasing constraining effects of dopamine on remote associations. Indeed, participants with reduced neural responses in the dopaminergic system of the right hemisphere (estimated by functional MRI in a reward task with positive and negative feedback), displayed higher creativity (estimated by convergent and divergent tasks), and increased associative processing in the right hemisphere (estimated by a lateralized lexical decision task). Our findings offer unprecedented empirical support for a crucial and specific contribution of the right hemisphere to creativity. More importantly our study provides a comprehensive view on potential determinants of human creativity, namely dopamine-related activity and associative processing. © The Author 2016.

Transcultural nursing and a care management partnership project.

Lazure, G; Vissandjée, B; Pepin, J; Kérouac, S

1997-09-01

This paper aims to illustrate how Leininger's Theory of Culture Care Diversity and Universality has influenced the research process of a study that emerged from a care management partnership between Canadian nursing teachers and Tunisian nurses. The purpose of the study was to investigate the meanings of care as viewed by university hospital-based Tunisian nurses. The qualitative analysis of data gathered through observation-participation and interviews highlights recurrent patterns and reveals three major professional care themes. For Tunisian nurses care means to secure the patient's cooperation towards the medical regimen within established rules in the hospital; to contribute to curing the patient by using current technology as well as by maintaining their technical skills and improving their medical knowledge; to take charge of the patient to assist the physician in treating disease. This study showed that Tunisian nurses emphasize curing rather than widely shared community values such as interdependence, intercommunication, understanding, presence and responsibility for others. Discussion of the study's findings draws upon the perspective provided by Freire's Oppressed Group Theory. In order to promote cultural congruence within the Care Management Partnership Project in Tunisia, the three predicted modes of care within Leininger's theory guide the decisions and actions for future nursing research and partnership activities.

Inhibition of motor cortex excitability of the contralesional hemisphere may improve dexterity of the affected hand after stroke. 40 patients (17 dominant hemispheric stroke, 23 non-dominant hemispheric stroke) with a mild to moderate upper limb motor impairment were enrolled in a double-blind, randomized, placebo-controlled trial with two parallel-groups. Both groups received 15 daily sessions of motor training preceded by either 1 Hz rTMS or sham rTMS. Behavioral and neurophysiological evaluations were performed at baseline, after the first week and after the third week of treatment, and after a 6 months follow-up. In both groups motor function of the affected hand improved significantly. Patients with stroke of the non-dominant hemisphere made a similar improvement, regardless of whether the motor training was preceded by sham or 1 Hz rTMS. Patients with stroke of the dominant hemisphere had a less favorable improvement than those with stroke of the non-dominant hemisphere after motor training preceded by sham rTMS. However, when 1 Hz rTMS preceded the motor training, patients with stroke of the dominant hemisphere made a similar improvement as those with stroke of the non-dominant hemisphere. Motor recovery of the affected upper limb after stroke is determined by dominance of the affected hemisphere. Stroke of the dominant hemisphere is associated with per se poorer improvement of the affected hand. 1 Hz rTMS over the contralesional M1 significantly improves dexterity of the affected hand in patients with stroke of the dominant hemisphere, but not in those with stroke of the non-dominant hemisphere.

Ng, Wan; Fergusson, Jennifer

2017-07-01

The issue of student disengagement in school science continues to pose a threat to lifting the participation rates of students undertaking STEM courses and careers in Australia and other countries globally. In Australia, several science initiatives to reverse the problem have been funded over the last two decades. Many of these initiatives involve partnerships with scientists, science educators and with industries, as is the case in this paper. The research in this paper investigated a recent partnership initiative between secondary science teachers, scientists and an educational technology company to produce science e-modules on adaptive learning platforms, enabling students to engage in personalised, inquiry-based learning and the investigation of real-world problems. One of the objectives of the partnership project was to build theoretical and pedagogical skills in teachers to deliver science by exposing them to new ways of engaging students with new digital tools, for example analytics. Using a mixed methods approach, the research investigated science teachers' pedagogical involvement in the partnership project and their perceptions of the project's impact on their teaching and students' learning. The findings indicate that the teachers believed that new technology could enhance their teaching and students' learning and that while their students were motivated by the online modules, there was still a need for scaffolding for many of the students. The effectiveness of this would depend on the teachers' ability to internalise the new technological and content knowledge resulting from the partnership and realign them with their existing pedagogical framework. The research is significant in identifying elements for successful partnership projects as well as challenges that need to be considered. It is significant in facilitating continuous discourse about new evidence-based pedagogical approaches to science education in engaging students to learn STEM subjects in a

Methods of dichotic listening as a research methodology for hemispheric interaction.

Kovyazina M.S.

2014-07-01

Full Text Available Experimental data was obtained from a dichotic listening test by patients with unilateral brain lesions and corpus callosum pathology (agenesis, cysts, degenerative changes, etc. Efficiency index analysis shows that interhemispheric interaction in the audioverbal sphere depends to a greater extent on the right hemisphere state. The dichotic listening technique is not an informative means of studying hemispheric interaction, since it does not allow a clear distinction between hemispheric symptoms and symptoms of pathology of the corpus callosum. Thus, violations of hemispheric relations caused by disorders of the corpus callosum and cerebral hemispheres change worth more right hemisphere activity.

Hemispheric biases and the control of visuospatial attention: an ERP study

Directory of Open Access Journals (Sweden)

Banich Marie T

2005-08-01

Full Text Available Abstract Background We examined whether individual differences in hemispheric utilization can interact with the intrinsic attentional biases of the cerebral hemispheres. Evidence suggests that the hemispheres have competing biases to direct attention contralaterally, with the left hemisphere (LH having a stronger bias than the right hemisphere. There is also evidence that individuals have characteristic biases to utilize one hemisphere more than the other for processing information, which can induce a bias to direct attention to contralateral space. We predicted that LH-biased individuals would display a strong rightward attentional bias, which would create difficulty in selectively attending to target stimuli in the left visual field (LVF as compared to right in the performance of a bilateral flanker task. Results Consistent with our hypothesis, flanker interference effects were found on the N2c event-related brain potential and error rate for LH-biased individuals in the Attend-LVF condition. The error rate effect was correlated with the degree of hemispheric utilization bias for the LH-Bias group. Conclusion We conclude that hemispheric utilization bias can enhance a hemisphere's contralateral attentional bias, at least for individuals with a LH utilization bias. Hemispheric utilization bias may play an important and largely unrecognized role in visuospatial attention.

2003-10-01

The isoprenoid pathway produces three key metabolites--endogenous digoxin, dolichol, and ubiquinone. This was assessed in patients with idiopathic pulmonary fibrosis and in individuals of differing hemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of idiopathic pulmonary fibrosis. All 15 cases of interstitial lung disease were right-handed/left hemispheric dominant by the dichotic listening test. The isoprenoidal metabolites--digoxin, dolichol, and ubiquinone, RBC membrane Na(+)-K+ ATPase activity, serum magnesium, tyrosine/tryptophan catabolic patterns, free radical metabolism, glycoconjugate metabolism, and RBC membrane composition--were assessed in idiopathic pulmonary fibrosis as well as in individuals with differing hemispheric dominance. In patients with idiopathic pulmonary fibrosis there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in patients with idiopathic pulmonary fibrosis. Isoprenoid pathway dysfunction con tributes to the pathogenesis of idiopathic pulmonary fibrosis. The biochemical patterns obtained in interstitial lung disease are similar to those obtained in left-handed/right hemispheric chemically dominant individuals by the dichotic listening test. However, all the patients with interstitial lung disease were right-handed/left hemispheric dominant by the dichotic listening test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Interstitial lung disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

A vision of graded hemispheric specialization.

Science.gov (United States)

Behrmann, Marlene; Plaut, David C

2015-11-01

Understanding the process by which the cerebral hemispheres reach their mature functional organization remains challenging. We propose a theoretical account in which, in the domain of vision, faces and words come to be represented adjacent to retinotopic cortex by virtue of the need to discriminate among homogeneous exemplars. Orthographic representations are further constrained to be proximal to typically left-lateralized language-related information to minimize connectivity length between visual and language areas. As reading is acquired, orthography comes to rely more heavily (albeit not exclusively) on the left fusiform region to bridge vision and language. Consequently, due to competition from emerging word representations, face representations that were initially bilateral become lateralized to the right fusiform region (albeit, again, not exclusively). We review recent research that describes constraints that give rise to this graded hemispheric arrangement. We then summarize empirical evidence from a variety of studies (behavioral, evoked response potential, functional imaging) across different populations (children, adolescents, and adults; left handers and individuals with developmental dyslexia) that supports the claims that hemispheric lateralization is graded rather than binary and that this graded organization emerges dynamically over the course of development. Perturbations of this system either during development or in adulthood provide further insights into the principles governing hemispheric organization. © 2015 New York Academy of Sciences.

Recognizing that partnership is both a process and a practice, the authors bring attention to the role of one’s relationship with self in the partnership model. Ways in which domination thinking becomes internalized and how it functions in our own inner lives is demonstrated. Through a close examination of seven key ways to cultivate a relationship of respect, peace, care, and compassion with self, the authors offer a simple tool to support the practice of partnership values from the inside out.

Strategic plans to conserve migratory species require detailed knowledge on species distribution, abundance, and habitat use over the annual cycle, but such data are lacking for most species. We developed a hemispheric approach to planning using spatiotemporally explicit species abundance models to prioritize land needed to conserve ≥17% of the global populations of 109 species of Neotropical migratory birds. The efficiency of annual cycle plans was evaluated in comparisons to single-season p...

The Civil Partnership Act 2004, which came into force in December 2005 allowing same-sex couples in the UK to register their relationship for the first time, celebrated its fifth anniversary in December 2010. This article examines civil partnership in England and Wales, five years on from its introduction. The characteristics of those forming civil partnerships between 2005 and 2010 including age, sex and previous marital/civil partnership status are examined. These are then compared with the characteristics of those marrying over the same period. Further comparisons are also made between civil partnership dissolutions and divorce. The article presents estimates of the number of people currently in civil partnerships and children of civil partners. Finally the article examines attitudes towards same-sex and civil partner couples both in the UK and in other countries across Europe.

Hypothalamic digoxin, hemispheric chemical dominance, and peptic ulcer disease.

Science.gov (United States)

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-10-01

The isoprenoid pathway produces three key metabolites--endogenous digoxin-like factor (EDLF) (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), ubiquinone (free radical scavenger), and dolichol (regulator of glycoconjugate metabolism). The pathway was assessed in peptic ulcer and acid peptic disease and its relation to hemispheric dominance studied. The activity of HMG CoA reductase, serum levels of EDLF, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in acid peptic disease, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. All the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listening test. The pathway was upregulated with increased EDLF synthesis in peptic ulcer disease (PUD). There was increase in tryptophan catabolites and reduction in tyrosine catabolites in these patients. The ubiquinone levels were low and free radical production increased. Dolichol and glycoconjugate levels were increased and lysosomal stability reduced in patients with acid peptic disease (APD). There was increase in cholesterol:phospholipid ratio with decreased glyco conjugate levels in membranes of patients with PUD. Acid peptic disease represents an elevated EDLF state which can modulate gastric acid secretion and the structure of the gastric mucous barrier. It can also lead to persistence of Helicobacter pylori infection. The biochemical pattern obtained in peptic ulcer disease is similar to those obtained in left-handed/right hemispheric chemically dominant individuals. But all the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listen ing test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Peptic ulcer disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

Health partnerships often use health professional training to change practice with the aim of improving quality of care. Interventions to change practice can learn from behavioural science and focus not only on improving the competence and capability of health professionals but also their opportunity and motivation to make changes in practice. We describe a project that used behavioural scientist volunteers to enable health partnerships to understand and use the theories, techniques and assessments of behavioural science. This paper outlines how The Change Exchange, a collective of volunteer behavioural scientists, worked with health partnerships to strengthen their projects by translating behavioural science in situ. We describe three case studies in which behavioural scientists, embedded in health partnerships in Uganda, Sierra Leone and Mozambique, explored the behaviour change techniques used by educators, supported knowledge and skill development in behaviour change, monitored the impact of projects on psychological determinants of behaviour and made recommendations for future project developments. Challenges in the work included having time and space for behavioural science in already very busy health partnership schedules and the difficulties in using certain methods in other cultures. Future work could explore other modes of translation and further develop methods to make them more culturally applicable. Behavioural scientists could translate behavioural science which was understood and used by the health partnerships to strengthen their project work.

When One Hemisphere Takes Control: Metacontrol in Pigeons (Columba livia)

Science.gov (United States)

Adam, Ruth; Güntürkün, Onur

2009-01-01

Background Vertebrate brains are composed of two hemispheres that receive input, compute, and interact to form a unified response. How the partially different processes of both hemispheres are integrated to create a single output is largely unknown. In some cases one hemisphere takes charge of the response selection – a process known as metacontrol. Thus far, this phenomenon has only been shown in a handful of studies with primates, mostly conducted in humans. Metacontrol, however, is even more relevant for animals like birds with laterally placed eyes and complete chiasmatic decussation since visual input to the hemispheres is largely different. Methodology/Principal Findings Homing pigeons (Columba livia) were trained with a color discrimination task. Each hemisphere was trained with a different color pair and therefore had a different experience. Subsequently, the pigeons were binocularly examined with two additional stimuli that combined the positive color of one hemisphere with a negative color that had been shown to the other, omitting the availability of a coherent solution and confronting the pigeons with a conflicting situation. Some of the pigeons responded to both stimuli, indicating that none of the hemispheres dominated the overall preference. Some birds, however, responded primarily to one of the conflicting stimuli, showing that they based their choice on the left- or right-monocularly learned color pair, indicating hemispheric metacontrol. Conclusions/Significance We could demonstrate for the first time that metacontrol is a widespread phenomenon that also exists in birds, and thus in principle requires no corpus callosum. Our results are closely similar to those in humans: monocular performance was higher than binocular one and animals displayed different modes of hemispheric dominance. Thus, metacontrol is a dynamic and widely distributed process that possibly constitutes a requirement for all animals with a bipartite brain to confront the

The canopy is the most direct and active interface layer of the interaction between plant and environment, and has important influence on energy exchange, biodiversity, ecosystem matter and climate change. The measurement about canopy structure of plant is an important foundation to analyze the pattern, process and operation mechanism of forest ecosystem. Through the study of canopy structure of plant, solar radiation, ambient wind speed, air temperature and humidity, soil evaporation, soil temperature and other forest environmental climate characteristics can be evaluated. Because of its accuracy and effectiveness, canopy structure measurement based on hemispherical photography has been widely studied. However, the traditional method of canopy structure hemispherical photogrammetry based on SLR camera and fisheye lens. This method is expensive and difficult to be used in some low-cost occasions. In recent years, smartphone technology has been developing rapidly. The smartphone not only has excellent image acquisition ability, but also has the considerable computational processing ability. In addition, the gyroscope and positioning function on the smartphone will also help to measure the structure of the canopy. In this paper, we present a smartphone based hemispherical photography system. The system consists of smart phones, low-cost fisheye lenses and PMMA adapters. We designed an Android based App to obtain the canopy hemisphere images through low-cost fisheye lenses and provide horizontal collimation information. In addition, the App will add the acquisition location tag obtained by GPS and auxiliary positioning method in hemisphere image information after the canopy structure hemisphere image acquisition. The system was tested in the urban forest after it was completed. The test results show that the smartphone based hemispherical photography system can effectively collect the high-resolution canopy structure image of the plant.

The effects of left and right monocular viewing on hemispheric activation.

Science.gov (United States)

Wang, Chao; Burtis, D Brandon; Ding, Mingzhou; Mo, Jue; Williamson, John B; Heilman, Kenneth M

2018-03-01

Prior research has revealed that whereas activation of the left hemisphere primarily increases the activity of the parasympathetic division of the autonomic nervous system, right-hemisphere activation increases the activity of the sympathetic division. In addition, each hemisphere primarily receives retinocollicular projections from the contralateral eye. A prior study reported that pupillary dilation was greater with left- than with right-eye monocular viewing. The goal of this study was to test the alternative hypotheses that this asymmetric pupil dilation with left-eye viewing was induced by activation of the right-hemispheric-mediated sympathetic activity, versus a reduction of left-hemisphere-mediated parasympathetic activity. Thus, this study was designed to learn whether there are changes in hemispheric activation, as measured by alteration of spontaneous alpha activity, during right versus left monocular viewing. High-density electroencephalography (EEG) was recorded from healthy participants viewing a crosshair with their right, left, or both eyes. There was a significantly less alpha power over the right hemisphere's parietal-occipital area with left and binocular viewing than with right-eye monocular viewing. The greater relative reduction of right-hemisphere alpha activity during left than during right monocular viewing provides further evidence that left-eye viewing induces greater increase in right-hemisphere activation than does right-eye viewing.

It's hard to play ball: A qualitative study of knowledge exchange and silo effects in public health.

Johnson, Rebecca; Grove, Amy; Clarke, Aileen

Partnerships in public health form an important component of commissioning and implementing services, in England and internationally. In this research, we examine the views of staff involved in a City-wide health improvement programme which ran from 2009 to 2013 in England. We examine the practicalities of partnership work in community settings, and we describe some of barriers faced when implementing a large, multi-organisation health improvement programme. Qualitative, semi-structured interviews were performed. Purposive sampling was used to identify potential participants in the programme: programme board of directors, programme and project managers and intervention managers. Interviews were conducted one-to-one. We conducted a thematic analysis using the 'one sheet of paper' technique. This involved analysing data deductively, moving from initial to axial coding, developing categories and then identifying emerging themes. Fifteen interviews were completed. Three themes were identified. The first theme reflects how poor communication approaches hindered the ability of partnerships to deliver their aims and objectives in a range of ways and for a range of reasons. Our second theme reflects how a lack of appropriate knowledge exchange hindered decision-making, affected trust and contributed to protectionist approaches to working. This lack of shared, and communicated, understanding of what type of knowledge is most appropriate and in which circumstance made meaningful knowledge exchange challenging for decision-making and partnership-working in the City-wide health improvement programme. Theme three demonstrates how perceptions about silos in partnership-working could be problematic, but silos themselves were at times beneficial to partnerships. This revealed a mismatch between rhetoric and a realistic understanding of what components of the programme were functional and which were more hindrance than help. There were high expectations placed on the concept of

Motivation, affect, and hemispheric asymmetry: power versus affiliation.

Science.gov (United States)

Kuhl, Julius; Kazén, Miguel

2008-08-01

In 4 experiments, the authors examined to what extent information related to different social needs (i.e., power vs. affiliation) is associated with hemispheric laterality. Response latencies to a lateralized dot-probe task following lateralized pictures or verbal labels that were associated with positive or negative episodes related to power, affiliation, or achievement revealed clear-cut laterality effects. These effects were a function of need content rather than of valence: Power-related stimuli were associated with right visual field (left hemisphere) superiority, whereas affiliation-related stimuli were associated with left visual field (right hemisphere) superiority. Additional results demonstrated that in contrast to power, affiliation primes were associated with better discrimination between coherent word triads (e.g., goat, pass, and green, all related to mountain) and noncoherent triads, a remote associate task known to activate areas of the right hemisphere.

Evaluating fMRI methods for assessing hemispheric language dominance in healthy subjects.

Science.gov (United States)

Baciu, Monica; Juphard, Alexandra; Cousin, Emilie; Bas, Jean François Le

2005-08-01

We evaluated two methods for quantifying the hemispheric language dominance in healthy subjects, by using a rhyme detection (deciding whether couple of words rhyme) and a word fluency (generating words starting with a given letter) task. One of methods called "flip method" (FM) was based on the direct statistical comparison between hemispheres' activity. The second one, the classical lateralization indices method (LIM), was based on calculating lateralization indices by taking into account the number of activated pixels within hemispheres. The main difference between methods is the statistical assessment of the inter-hemispheric difference: while FM shows if the difference between hemispheres' activity is statistically significant, LIM shows only that if there is a difference between hemispheres. The robustness of LIM and FM was assessed by calculating correlation coefficients between LIs obtained with each of these methods and manual lateralization indices MLI obtained with Edinburgh inventory. Our results showed significant correlation between LIs provided by each method and the MIL, suggesting that both methods are robust for quantifying hemispheric dominance for language in healthy subjects. In the present study we also evaluated the effect of spatial normalization, smoothing and "clustering" (NSC) on the intra-hemispheric location of activated regions and inter-hemispheric asymmetry of the activation. Our results have shown that NSC did not affect the hemispheric specialization but increased the value of the inter-hemispheric difference.

The solar northern and southern hemispheres exhibit differences in their intensities and time profiles of the activity cycles. The time variation of these properties was studied in a previous article covering the data from Cycles 12–23. The hemispheric phase lags exhibited a characteristic variation: the leading role was exchanged between hemispheres every four cycles. The present work extends the investigation of this variation using the data of Staudacher and Schwabe in Cycles 1–4 and 7–10 as well as Spörer’s data in Cycle 11. The previously observed variation cannot be clearly recognized using the data of Staudacher, Schwabe, and Spörer. However, it is more interesting that the phase lags of the reversals of the magnetic fields at the poles follow the same variations as those of the hemispheric cycles in Cycles 12–23, i.e., one of the hemispheres leads in four cyles and the leading role jumps to the opposite hemisphere in the next four cycles. This means that this variation is a long-term property of the entire solar dynamo mechanism, for both the toroidal and poloidal fields, which hints at an unidentified component of the process responsible for the long-term memory.

CMB-S4 and the hemispherical variance anomaly

Science.gov (United States)

O'Dwyer, Márcio; Copi, Craig J.; Knox, Lloyd; Starkman, Glenn D.

2017-09-01

Cosmic microwave background (CMB) full-sky temperature data show a hemispherical asymmetry in power nearly aligned with the Ecliptic. In real space, this anomaly can be quantified by the temperature variance in the Northern and Southern Ecliptic hemispheres, with the Northern hemisphere displaying an anomalously low variance while the Southern hemisphere appears unremarkable [consistent with expectations from the best-fitting theory, Lambda Cold Dark Matter (ΛCDM)]. While this is a well-established result in temperature, the low signal-to-noise ratio in current polarization data prevents a similar comparison. This will change with a proposed ground-based CMB experiment, CMB-S4. With that in mind, we generate realizations of polarization maps constrained by the temperature data and predict the distribution of the hemispherical variance in polarization considering two different sky coverage scenarios possible in CMB-S4: full Ecliptic north coverage and just the portion of the North that can be observed from a ground-based telescope at the high Chilean Atacama plateau. We find that even in the set of realizations constrained by the temperature data, the low Northern hemisphere variance observed in temperature is not expected in polarization. Therefore, observing an anomalously low variance in polarization would make the hypothesis that the temperature anomaly is simply a statistical fluke more unlikely and thus increase the motivation for physical explanations. We show, within ΛCDM, how variance measurements in both sky coverage scenarios are related. We find that the variance makes for a good statistic in cases where the sky coverage is limited, however, full northern coverage is still preferable.

Knowledge exchange in the UK CLAHRCs.

Science.gov (United States)

Racko, Girts

2018-04-09

Purpose The purpose of this paper is to examine how knowledge exchange between academics and clinicians in Collaborations for Leadership in Applied Health Research and Care (CLAHRCs) is influenced by their social position based on their symbolic and social capitals, that is, their personal professional status and connections to high-status professional peers, knowledge brokers, and unfamiliar professional peers. Design/methodology/approach Using an online survey, the author triangulates the cross-sectional measurement of the effects of academic and clinicians' social position in the initial and later phases of CLAHRCs with the longitudinal measurement of these effects over a two-year period. Findings First, academics and clinicians with a higher personal professional status are more likely to develop joint networks and decision making both in the early and later phases of a CLAHRC. Second, academics and clinicians who are more connected to higher status occupational peers are more likely to develop joint networks in the early phase of a knowledge exchange partnership but are less likely to become engaged in joint networks over time. Third, involvement of knowledge brokers in the networks of academics and clinicians is likely to facilitate their inter-professional networking only in the later partnership phase. Practical implications Academics and clinicians' capitals have a distinctive influence on knowledge exchange in the early and later phases of CLAHRCs and on a change in knowledge exchange over a two-year period. Originality/value Prior research on CLAHRCs has examined how knowledge exchange between academics and clinicians can be encouraged by the creation of shared governance mechanisms. The author advances this research by highlighting the role of their social position in facilitating knowledge exchange.

Holocene sea-level fluctuation in the southern hemisphere

Science.gov (United States)

Isla, Federico Ignacio

If rising sea levels dominate in the northern hemisphere (NH), falling or fluctuating sea levels predominate in the southern hemisphere (SH). Endogenic processes (tectonics, isostasy or geoidal changes) could explain local or regional mean sea level (MSL) fluctuations but not an hemispherical one. Evidence from South America, Africa, Antarctica, Australia and the Pacific and Indian Oceans suggest that the Holocene transgression rose above the present MSL, in higher latitudes before the tropics. By plotting latitude against the age of MSL arrival at present coasts, good correlation is observed. Oceanic salinity mixing has been already proposed to explain this mid-Holocene sea-level fluctuation. Climate could be the only factor responsible for this hemisphere-wide behavior of MSL. It has been suggested previously that the climate of the SH precedes that of the NH by 3000 years. The climatic optimum, or maximum warmth, occurred predominantly about 6000 BP in the NH, but about 10-9000 BP in the SH. Short-term climatic effects on the sea level (monsoons, southern oscillation/El Niño phenomena) should have significant occurrences during the past in the windiest oceanic hemisphere. This latitudinal trend in former MSL should be considered when using shorelines as reference points for measuring vertical crustal movements.

Investment in the Western Hemisphere energy market

International Nuclear Information System (INIS)

Gillam, P.J.

1991-01-01

This paper reports that the main characteristics of Western Hemisphere energy markets are well known to those in the energy industry. The United States sits in the northern half of the hemisphere, importing more and more oil from the rest of the world. Brazil, with a market one-tenth of the size of the United Sates, sits in the southern half of the hemisphere, importing less and less oil from the rest of the world. Venezuela sits in the center with an eye to the future as a long-term player in the world petroleum industry. Venezuela has 6 or 7 percent of the world's known conventional petroleum reserves, plus an uncountable bitumen resource which is now being commercialized as Orimulsion, a low-emission substitute for coal. The United States is circled by major producing countries with smaller exports, such as Mexico and Canada, and there are smaller producing or consuming countries of which Colombia is the largest exporter and Argentian the largest importer. The United States dominates the numbers. Half of British Petroleum's (BP) investments have been in the energy industry of the Western Hemisphere. We are maintaining that proportion, but opportunities are becoming more difficult to find

Hypothalamic-mediated model for systemic lupus erythematosis: relation to hemispheric chemical dominance.

Science.gov (United States)

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-11-01

The isoprenoid pathway including endogenous digoxin was assessed in systemic lupus erythematosis (SLE). All the patients with SLE were right-handed/left hemispheric dominant by the dichotic listening test. This was also studied for comparison in patients with right hemispheric and left hemispheric dominance. The isoprenoid pathway was upregulated with increased digoxin synthesis in patients with SLE and in those with right hemispheric dominance. In this group of patients (i) the tryptophan catabolites were increased and the tyrosine catabolites reduced, (ii) the dolichol and glycoconjugate levels were elevated, (iii) lysosomal stability was reduced, (iv) ubiquinone levels were low and free radical levels increased, and (v) the membrane cholesterol:phospholipid ratios were increased and membrane glycoconjugates reduced. On the other hand, in patients with left hemispheric dominance the reverse patterns were obtained. The biochemical patterns obtained in SLE is similar to those obtained in left-handed/right hemispheric chemically dominant individuals. But all the patients with SLE were right-handed/left hemispheric dominant by the dichotic listening test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. SLE occurs in right hemispheric chemically dominant individuals, and is a reflection of altered brain function. The role of the isoprenoid pathway in the pathogenesis of SLE and its relation to hemispheric dominance is discussed.

Persistent gaps in the availability of essential medicines have slowed the achievement of global health targets. Despite the supply chain knowledge and expertise that ministries of health might glean from other industries, limited empirical research has examined the process of knowledge transfer from other industries into global public health. We examined a partnership designed to improve the availability of medical supplies in Tanzania by transferring knowledge from The Coca-Cola system to Tanzania's Medical Stores Department (MSD). We conducted a process evaluation including in-depth interviews with 70 participants between July 2011 and May 2014, corresponding to each phase of the partnership, with focus on challenges and strategies to address them, as well as benefits perceived by partners. Partners faced challenges in (1) identifying relevant knowledge to transfer, (2) translating operational solutions from Coca-Cola to MSD, and (3) maintaining momentum between project phases. Strategies to respond to these challenges emerged through real-time problem solving and included (1) leveraging the receptivity of MSD leadership, (2) engaging a boundary spanner to identify knowledge to transfer, (3) promoting local recognition of commonalities across industries, (4) engaging external technical experts to manage translation activities, (5) developing tools with visible benefits for MSD, (6) investing in local relationships, and (7) providing time and space for the partnership model to evolve. Benefits of the partnership perceived by MSD staff included enhanced collaboration and communication, more proactive orientations in managing operations, and greater attention to performance management. Benefits perceived by Coca-Cola staff included strengthened knowledge transfer capability and enhanced job satisfaction. Linking theoretical constructs with practical experiences from the field, we highlight the challenges, emergent strategies, and perceived benefits of a partnership

1995-01-01

Activities of the United States Energy Association were reviewed, as well as the manner in which its members are benefitting from the Association's programs. The principal cooperative program set up is the Utility Partnership Program, which was described. Through this program the Association is matching US companies, both electric utilities and gas utilities, with counterparts in Eastern Europe or the former Soviet Union. So far, about 25 partnerships were signed, e.g. in the Czech Republic, in Kazakhstan, in Poland, and in Slovakia. It was estimated that the return to the United States from the investments made by the American government in these Utility Partnership Programs has been well over 100-fold

2013-01-01

Full Text Available Background. Collaborative nursing research across academic and practice settings is imperative to generate knowledge to improve patient care. Models of academic/practice partnerships for nursing research are lacking. This paper reports data collected before and during a one-day retreat for nurse researchers and administrators from local universities and health care organizations designed to establish a regional nursing research partnership. Methods. Quantitative and qualitative methods were used to address the study aims: (1 to assess research involvement and institutional research resources; (2 to assess interest in and concerns regarding cross-institutional collaborations; and (3 to describe perceptions of the purpose of a partnership and resources needed to ensure success. Results. Participants (n=49 had differing perceptions of accessibility to resources; participants in practice settings reported less accessibility to resources, notably grant development, informatics, and research assistant support. Participants were interested in collaboration although concerns about conflict of interest were expressed. Four themes related to partnering were identified: harnessing our nursing voice and identity; developing as researchers; staying connected; and positioning for a collaborative project. Conclusion. Academic-practice research collaborations will become increasingly important with health care system changes. Strategies to develop and sustain productive partnerships should be supported.

Reversible hemispheric hypoperfusion in two cases of SMART syndrome.

Science.gov (United States)

Wai, Karmen; Balabanski, Anna; Chia, Nicholas; Kleinig, Timothy

2017-09-01

Stroke-like migraine attacks after radiation therapy (SMART) syndrome manifests as prolonged episodes of cortical dysfunction, years after cranial irradiation. We present two cases demonstrating reversible hemispheric hypoperfusion. Case 1 presented with left hemispheric symptoms following previous similar episodes. CT perfusion (CTP) demonstrated reversible hemispheric hypoperfusion; subsequent investigations were consistent with SMART syndrome. Case 2 presented following the third episode of a hemispheric syndrome with near-identical CTP abnormalities. L-arginine was administered with rapid reversal of clinical and CTP abnormalities. We conclude that SMART syndrome may demonstrate significant hypoperfusion on hyperacute CTP without subsequent infarction. Impaired cerebrovascular autoregulation probably contributes to cortical dysfunction in SMART syndrome. L-arginine warrants investigation as a potential treatment. Copyright © 2017 Elsevier Ltd.

Clinical Focus on Prosodic, Discursive and Pragmatic Treatment for Right Hemisphere Damaged Adults: What's Right?

Directory of Open Access Journals (Sweden)

Perrine Ferré

2011-01-01

Full Text Available Researchers and clinicians acknowledge today that the contribution of both cerebral hemispheres is necessary to a full and adequate verbal communication. Indeed, it is estimated that at least 50% of right brain damaged individuals display impairments of prosodic, discourse, pragmatics and/or lexical semantics dimensions of communication. Since the 1990's, researchers have focused on the description and the assessment of these impairments and it is only recently that authors have shown interest in planning specific intervention approaches. However, therapists in rehabilitation settings still have very few available tools. This review of recent literature demonstrates that, even though theoretical knowledge needs further methodological investigation, intervention guidelines can be identified to target right hemisphere damage communication impairments in clinical practice. These principles can be incorporated by speech and language pathologists, in a structured intervention framework, aiming at fully addressing prosodic, discursive and pragmatic components of communication.

We evaluated two methods for quantifying the hemispheric language dominance in healthy subjects, by using a rhyme detection (deciding whether couple of words rhyme) and a word fluency (generating words starting with a given letter) task. One of methods called 'flip method' (FM) was based on the direct statistical comparison between hemispheres' activity. The second one, the classical lateralization indices method (LIM), was based on calculating lateralization indices by taking into account the number of activated pixels within hemispheres. The main difference between methods is the statistical assessment of the inter-hemispheric difference: while FM shows if the difference between hemispheres' activity is statistically significant, LIM shows only that if there is a difference between hemispheres. The robustness of LIM and FM was assessed by calculating correlation coefficients between LIs obtained with each of these methods and manual lateralization indices MLI obtained with Edinburgh inventory. Our results showed significant correlation between LIs provided by each method and the MIL, suggesting that both methods are robust for quantifying hemispheric dominance for language in healthy subjects. In the present study we also evaluated the effect of spatial normalization, smoothing and 'clustering' (NSC) on the intra-hemispheric location of activated regions and inter-hemispheric asymmetry of the activation. Our results have shown that NSC did not affect the hemispheric specialization but increased the value of the inter-hemispheric difference.

Classification of hemispheric monthly mean stratospheric potential vorticity fields

Directory of Open Access Journals (Sweden)

R. Huth

Full Text Available Monthly mean NCEP reanalysis potential vorticity fields at the 650 K isentropic level over the Northern and Southern Hemispheres between 1979 and 1997 were studied using multivariate analysis tools. Principal component analysis in the T-mode was applied to demonstrate the validity of such statistical techniques for the study of stratospheric dynamics and climatology. The method, complementarily applied to both the raw and anomaly fields, was useful in determining and classifying the characteristics of winter and summer PV fields on both hemispheres, in particular, the well-known differences in the behaviour and persistence of the polar vortices. It was possible to identify such features as sudden warming events in the Northern Hemisphere and final warming dates in both hemispheres. The stratospheric impact of other atmospheric processes, such as volcanic eruptions, also identified though the results, must be viewed at this stage as tentative. An interesting change in behaviour around 1990 was detected over both hemispheres.

Community-based participatory research and integrated knowledge translation: advancing the co-creation of knowledge.

Jull, Janet; Giles, Audrey; Graham, Ian D

2017-12-19

Better use of research evidence (one form of "knowledge") in health systems requires partnerships between researchers and those who contend with the real-world needs and constraints of health systems. Community-based participatory research (CBPR) and integrated knowledge translation (IKT) are research approaches that emphasize the importance of creating partnerships between researchers and the people for whom the research is ultimately meant to be of use ("knowledge users"). There exist poor understandings of the ways in which these approaches converge and diverge. Better understanding of the similarities and differences between CBPR and IKT will enable researchers to use these approaches appropriately and to leverage best practices and knowledge from each. The co-creation of knowledge conveys promise of significant social impacts, and further understandings of how to engage and involve knowledge users in research are needed. We examine the histories and traditions of CBPR and IKT, as well as their points of convergence and divergence. We critically evaluate the ways in which both have the potential to contribute to the development and integration of knowledge in health systems. As distinct research traditions, the underlying drivers and rationale for CBPR and IKT have similarities and differences across the areas of motivation, social location, and ethics; nevertheless, the practices of CBPR and IKT converge upon a common aim: the co-creation of knowledge that is the result of knowledge user and researcher expertise. We argue that while CBPR and IKT both have the potential to contribute evidence to implementation science and practices for collaborative research, clarity for the purpose of the research-social change or application-is a critical feature in the selection of an appropriate collaborative approach to build knowledge. CBPR and IKT bring distinct strengths to a common aim: to foster democratic processes in the co-creation of knowledge. As research

Kral, Andrej; Heid, Silvia; Hubka, Peter; Tillein, Jochen

2013-01-01

The present study investigates the hemispheric contributions of neuronal reorganization following early single-sided hearing (unilateral deafness). The experiments were performed on ten cats from our colony of deaf white cats. Two were identified in early hearing screening as unilaterally congenitally deaf. The remaining eight were bilaterally congenitally deaf, unilaterally implanted at different ages with a cochlear implant. Implanted animals were chronically stimulated using a single-channel portable signal processor for two to five months. Microelectrode recordings were performed at the primary auditory cortex under stimulation at the hearing and deaf ear with bilateral cochlear implants. Local field potentials (LFPs) were compared at the cortex ipsilateral and contralateral to the hearing ear. The focus of the study was on the morphology and the onset latency of the LFPs. With respect to morphology of LFPs, pronounced hemisphere-specific effects were observed. Morphology of amplitude-normalized LFPs for stimulation of the deaf and the hearing ear was similar for responses recorded at the same hemisphere. However, when comparisons were performed between the hemispheres, the morphology was more dissimilar even though the same ear was stimulated. This demonstrates hemispheric specificity of some cortical adaptations irrespective of the ear stimulated. The results suggest a specific adaptation process at the hemisphere ipsilateral to the hearing ear, involving specific (down-regulated inhibitory) mechanisms not found in the contralateral hemisphere. Finally, onset latencies revealed that the sensitive period for the cortex ipsilateral to the hearing ear is shorter than that for the contralateral cortex. Unilateral hearing experience leads to a functionally-asymmetric brain with different neuronal reorganizations and different sensitive periods involved.

Hypothalamic digoxin, hemispheric chemical dominance, and inflammatory bowel disease.

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-09-01

The isoprenoid pathway produces three key metabolites--endogenous digoxin, dolichol, and ubiquinone. It was considered pertinent to assess the pathway in inflammatory bowel disease (ulcerative colitis and regional ileitis). Since endogenous digoxin can regulate neurotransmitter transport, the pathway and the related cascade were also assessed in individuals with differing hemispheric dominance to find out the role of hemispheric dominance in its pathogenesis. All the patients with inflammatory bowel disease were right-handed/left hemispheric dominant by the dichotic listening test. The following parameters were measured in patients with inflammatory bowel disease and in individuals with differing hemispheric dominance: (1) plasma HMG CoA reductase, digoxin, dolichol, ubiquinone, and magnesium levels; (2) tryptophan/tyrosine catabolic patterns; (3) free-radical metabolism; (4) glycoconjugate metabolism; and (5) membrane composition and RBC membrane Na+-K+ ATPase activity. Statistical analysis was done by ANOVA. In patients with inflammatory bowel disease there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in these groups of patients. Inflammatory bowel disease is associated with an upregulated isoprenoid pathway and elevated digoxin secretion from the hypothalamus. This can contribute to immune activation, defective glycoprotein bowel antigen presentation, and autoimmunity and a schizophreniform psychosis important in its pathogenesis. The biochemical patterns obtained in inflammatory bowel disease is similar to those obtained in left-handed/right hemispheric dominant individuals by the dichotic listening test. But all the patients with peptic ulcer disease were right

2011-01-01

Full Text Available The purpose of the study was to examine university-school partnerships in the process of teacher education. The research question that guided the study was how teacher educators partner with schools in teacher training. A qualitative study was preferred because the aim was to gather information and opinions on how teacher educators trained student teachers as well as to provide a forum for pre-service student teachers to air their views about how they were trained. Twenty- six lecturers and nine student focus groups, purposively sampled, participated in the study. An interview was used for data collection and Holliday's thematic approach was used to analyse the data. The research revealed that there was a weak partnership between teacher education and schools. The study recommends the creation of third spaces in teacher education which involve an "equal and more dialectical relationship between academic and practitioner knowledge" in support of student teachers' learning.

Hemispheric asymmetry in the influence of language on visual perception.

Science.gov (United States)

Sun, Yanliang; Cai, Yongchun; Lu, Shena

2015-07-01

Many studies have shown that language can affect visual perception; however, our understanding of the neural basis of linguistic influence is inadequate. This can be investigated by examining the hemispheric asymmetry of linguistic influence. The left and right hemispheres are dominant in close and distant semantic processing, respectively. In this study, we investigated whether the hemispheric asymmetry of semantic processing led to hemispheric asymmetry for concept priming on the detection of objects degraded by continuous flash suppression. We combined a priming paradigm with the divided visual field paradigm and used continuous flash suppression, which renders objects invisible. The results indicated that the hemispheric asymmetry of semantic processing led to a right lateralization in the influence of more abstract concepts on visual perception. The lateralization of brain connectomes may be the underlying neural basis of this effect. Copyright © 2015 Elsevier Inc. All rights reserved.

During the period of October 1, 2003, through September 30, 2005, the Plains CO2 Reduction (PCOR) Partnership, identified geologic and terrestrial candidates for near-term practical and environmentally sound carbon dioxide (CO2) sequestration demonstrations in the heartland of North America. The PCOR Partnership region covered nine states and three Canadian provinces. The validation test candidates were further vetted to ensure that they represented projects with (1) commercial potential and (2) a mix that would support future projects both dependent and independent of CO2 monetization. This report uses the findings contained in the PCOR Partnership's two dozen topical reports and half-dozen fact sheets as well as the capabilities of its geographic information system-based Decision Support System to provide a concise picture of the sequestration potential for both terrestrial and geologic sequestration in the PCOR Partnership region based on assessments of sources, sinks, regulations, deployment issues, transportation, and capture and separation. The report also includes concise action plans for deployment and public education and outreach as well as a brief overview of the structure, development, and capabilities of the PCOR Partnership. The PCOR Partnership is one of seven regional partnerships under Phase I of the U.S. Department of Energy National Energy Technology Laboratory's Regional Carbon Sequestration Partnership program. The PCOR Partnership, comprising 49 public and private sector members, is led by the Energy & Environmental Research Center at the University of North Dakota. The international PCOR Partnership region includes the Canadian provinces of Alberta, Saskatchewan, and Manitoba and the states of Montana (part), Wyoming (part), North Dakota, South Dakota, Nebraska, Missouri, Iowa, Minnesota, and Wisconsin.

Konsynski, B R; McFarlan, F W

How can one company gain access to another's resources or customers without merging ownership, management, or plotting a takeover? The answer is found in new information partnerships, enabling diverse companies to develop strategic coalitions through the sharing of data. The key to cooperation is a quantum improvement in the hardware and software supporting relational databases: new computer speeds, cheaper mass-storage devices, the proliferation of fiber-optic networks, and networking architectures. Information partnerships mean that companies can distribute the technological and financial exposure that comes with huge investments. For the customer's part, partnerships inevitably lead to greater simplification on the desktop and more common standards around which vendors have to compete. The most common types of partnership are: joint marketing partnerships, such as American Airline's award of frequent flyer miles to customers who use Citibank's credit card; intraindustry partnerships, such as the insurance value-added network service (which links insurance and casualty companies to independent agents); customer-supplier partnerships, such as Baxter Healthcare's electronic channel to hospitals for medical and other equipment; and IT vendor-driven partnerships, exemplified by ESAB (a European welding supplies and equipment company), whose expansion strategy was premised on a technology platform offered by an IT vendor. Partnerships that succeed have shared vision at the top, reciprocal skills in information technology, concrete plans for an early success, persistence in the development of usable information for all partners, coordination on business policy, and a new and imaginative business architecture.

We used a Support Vector Machine (SVM) classifier to assess hemispheric pattern of language dominance of 47 individuals categorized as non-typical for language from their hemispheric functional laterality index (HFLI) measured on a sentence minus word-list production fMRI-BOLD contrast map. The SVM classifier was trained at discriminating between Dominant and Non-Dominant hemispheric language production activation pattern on a group of 250 participants previously identified as Typicals (HFLI strongly leftward). Then, SVM was applied to each hemispheric language activation pattern of 47 non-typical individuals. The results showed that at least one hemisphere (left or right) was found to be Dominant in every, except 3 individuals, indicating that the "dominant" type of functional organization is the most frequent in non-typicals. Specifically, left hemisphere dominance was predicted in all non-typical right-handers (RH) and in 57.4% of non-typical left-handers (LH). When both hemisphere classifications were jointly considered, four types of brain patterns were observed. The most often predicted pattern (51%) was left-dominant (Dominant left-hemisphere and Non-Dominant right-hemisphere), followed by right-dominant (23%, Dominant right-hemisphere and Non-Dominant left-hemisphere) and co-dominant (19%, 2 Dominant hemispheres) patterns. Co-non-dominant was rare (6%, 2 Non-Dominant hemispheres), but was normal variants of hemispheric specialization. In RH, only left-dominant (72%) and co-dominant patterns were detected, while for LH, all types were found, although with different occurrences. Among the 10 LH with a strong rightward HFLI, 8 had a right-dominant brain pattern. Whole-brain analysis of the right-dominant pattern group confirmed that it exhibited a functional organization strictly mirroring that of left-dominant pattern group.

Elizabeth Chinomona

2016-11-01

Full Text Available Corporate social responsibility (CSR is crucial for competitive advantage and survival of firms globally. In the pursuit of excellence, many firms have embarked on CSR programs, considering that it is not a financial burden but a strategic roadmap to increase and maintain their brand reputation, to overcome competitive pressures successfully and to efficiently and effectively lower operating cost with profit maximisation through innovation and supply chain partnership. However, in the process of becoming good players of CSR to society, innovative dimension for sustainability as well as an organisation’s supply chain partnership may be essential determinants to enhance good firm business processes and performance activities. In other words, to realise CSR, firms should have a strong environmental measure and well-integrated supply chain practices closely related to their business objectives and structures. The purpose of this paper, therefore, is to examine the influence of CSR on innovation, supply chain partnership and firm competitiveness on firms around Vanderbijlpark, South Africa. Through a quantitative method using smart PLS, this study tested the relationships among the four variables, which are CSR, innovation, supply chain partnership and firm competitiveness. The results showed that there is a positive relationship between the four proposed hypotheses. H1: There is a positive relationship between CSR and innovation; H2: There is a positive relationship between CSR and supply chain partnership; H3: There is a positive relationship between innovation and firm competitiveness; H4: There is a positive relationship between supply chain partnership and firm competitiveness. The proposed study is expected to have practical and theoretical implications to policy makers and managers. In addition, it will provide added insights and new knowledge to the existing body of literature hitherto not studied extensively in South African firms

Given the importance of partnership in improving health care outcomes among children, there is a substantial need to understand better what partnership means to parents and physicians. The goal of this study was to develop a partnership survey that was based on parents' and pediatricians' opinions about the key concepts of partnership. Parents of patients visiting an affluent suburban private practice and a federally qualified health center, and 2 groups of pediatricians, were asked to review 61 partnership concepts and identify those they considered as being important to partnership. Parents and pediatricians from both practices agreed that 42 (68.9%) of the concepts were important to partnership. Sixteen of these concepts were dropped because they were redundant. Parents from both the suburban practice and health center identified 5 (8.2%) concepts that they believed contributed to partnership. Seven (11.5%) concepts were viewed as important to parents and pediatricians from the suburban practice but not to parents from the health center. Significant socioeconomic differences between the 2 parent groups suggested factors that explained the differences between parent groups. The 38 concepts endorsed by parents and pediatricians provided a nuanced view of partnership and formed the Parent Pediatrician Partnership Survey. © Copyright 2016 by the American Board of Family Medicine.

Providing nursing students with an opportunity for hands on use of advanced healthcare technology is critical to the development of highly competent nurses who are prepared not only to fully interact in the healthcare domain, but to also participate in its re-engineering via IT. The academic institution with an integrated IT solution in clinical simulation labs can become a place where students can learn the skills, understand the potential, participate in the selection and evaluation of software systems and eventually help to craft IT solutions that benefit both the patient and the practice of nursing and medicine. As the healthcare environment continues to change - pushing curricular redesign, the expectation that educators will increase the integration of IT into coursework and clinical experiences is increasing. The challenge however, is not only to educate the students, but to also educate faculty who often possess limited amounts of IT knowledge. Faculties, like students, have limited time and learning outcomes are enhanced when hands-on and practical educational opportunities are available. This presentation therefore will not only focus on the student; instead, the gestalt of integrated teaching/learning from faculty and student perspectives will be addressed. The challenges, including identifying partnership opportunities, identifying financial resources to support such partnerships, gaining institutional support, determining criteria to evaluate student performance, and strategies for engendering faculty support will be discussed, along with solutions on how they can be overcome. The presentation will also highlight the benefits of the partnership for both the institution and the industry vendor. The institution can benefit from the access to the vendor's software, hardware, and expertise. By using advanced clinical solutions in the classroom and hospital setting

An Earth System Scientist Network for Student and Scientist Partnerships

Successful student and scientist partnerships require that there is a mutual benefit from the partnership. This means that the scientist needs to be able to see the advantage of having students work on his/her project, and the students and teachers need to see that the students contribute to the project and develop the skills in inquiry and the content knowledge in the geosciences that are desired. Through the Earth System Scientist Network (ESSN) for Student and Scientist Partnerships project we are working toward developing scientific research projects for the participation of high school students. When these research projects are developed they will be posted on the ESSN web site that will appear in the Digital Library for Earth System Education (DLESE). In DLESE teachers and students who are interested in participating in a research program will be able to examine the criteria for each project and select the one that matches their needs and situation. In this paper we will report on how the various ESSN research projects are currently being developed to assure that both the scientist and the students benefit from the partnership. The ESSN scientists are working with a team of scientists and educators to 1) completely define the research question that the students will be addressing, 2) determine what role the students will have in the project, 3) identify the data that the students and teachers will work with, 4) map out the scientific protocols that the students will follow, and 5) determine the background and support materials needed to facilitate students successfully participating in the project. Other issues that the team is addressing include 1) identifying the selection criteria for the schools, 2) identifying rewards and recognition for the students and teacher by the scientist, and 3) identifying issues in Earth system science, relevant to the scientists data, that the students and teachers could use as a guide help develop students investigative

Full Text Available Since 1997 universities in South Africa have been encouraged to be responsive to the needs of communities, to encourage broader participation and to address issues of access in higher education (Department of Education 1997. This transformative agenda was found to be especially compelling in the case of rural-based South African universities, which often serve historically disadvantaged black populations in areas that are both under-resourced and underdeveloped (Nkomo & Sehoole 2007, pp. 235–36. In 2006 the traditional leadership of a local community approached the University of Venda to propose a partnership. This prompted the researcher to conduct a qualitative study, which sought to explore and describe community members’ views of what they understood to be a quality partnership. Thirty-seven community representatives were engaged in individual as well as focus group interviews. These representatives were identified first through a stakeholder analysis procedure that sought to determine who in the community would have valuable input for the university-community partnership. As a point of departure, the following two questions were asked consecutively: What are your needs and expectations of a partnership with the university and what would you regard as a quality partnership between the HEI and the community? The sample selection was purposive, utilising the snowball technique. Data was transcribed and analysed using Tesch’s eight-step method (Tesch 1990, in Creswell 1994, p. 155. Interview data and field notes were co-coded, crosschecked and triangulated. Feedback workshops were conducted with the community to confirm the findings. A consensus was reached that four main requirements emerged from the data: —Balance the partnership objectives of both parties —Ensure an unexploitative partnership —Share power and control in the partnership —Maintain and monitor the partnership. This article provides a brief overview of the national

To identify the intangible elements that characterize the successful effort to fight Chagas disease in the Americas, determine how they contributed to the overall success of the partnership, and learn lessons from the experience that could be applied to other programs. This study was based on the Partnership Assessment Tool (PAT) developed by the Nuffield Institute for Health ("the Institute") at the University of Leeds (London). The PAT draws heavily on scientific literature and the extensive experience of sociologists and health experts working for the Institute. The Pan American Health Organization (PAHO) modified the tool slightly to adapt it to its needs and provide a general structure for the study. The six key principles of the PAT framework were applied in the design of the research questionnaires. The findings show that a successful collaboration requires a clear objective; a good-quality pool of data; and comprehensive qualitative and quantitative knowledge of the problem, its dimensions, and its impact. The collaboration was elaborated from a common idea and a shared, quantified plan based on data gathered by independent scientists plus a strategy with explicit milestones. The clarity of purpose allowed for an improved synergy of efforts and made it possible to resolve differences in opinions and approaches. PAHO's experience with effective collaborations such as the joint initiative to fight Chagas disease provides a rich knowledge base for analysis of the advantages, limitations, and paradigms of community involvement, collaborative practices, and partnerships.

The use of a dyadic lens to assess and leverage academic and community partners' readiness to conduct community-based participatory research (CBPR) has not been systematically investigated. With a lack of readiness to conduct CBPR, the partnership and its products are vulnerable. The purpose of this qualitative study was to explore the dimensions and key indicators necessary for academic and community partnership readiness to conduct CBPR. Key informant interviews and focus groups (n = 36 participants) were conducted with academic and community participants who had experiences with CBPR partnerships. A 'framework analysis' approach was used to analyze the data and generate a new model, CBPR Partnership Readiness Model. Antecedents of CBPR partnership readiness are a catalyst and mutual interest. The major dimensions of the CBPR Partnership Readiness Model are (i) goodness of fit, (ii) capacity, and (iii) operations. Preferred outcomes are sustainable partnership and product, mutual growth, policy and social and health impact on the community. CBPR partnership readiness is an iterative and dynamic process, partnership and issue specific, influenced by a range of environmental and contextual factors, amenable to change and essential for sustainability and promotion of health and social change in the community.

Hemispheric specialization is reliably demonstrated in patients with unilateral lesions or disconnected hemispheres, but is inconsistent in healthy populations. The reason for this paradox is unclear. We propose that functional hemispheric specialization in healthy participants depends upon functional brain states at stimulus arrival (FBS). Brain activity was recorded from 123 surface electrodes while 22 participants (11 women) performed lateralized lexical decisions (left hemisphere processi...

Full Text Available Background: In political and other debates much of attention is paid to public – private partnerships (PPPs. These partnerships are perceived as a tool of meeting public demand by private supply. In theory there are at least four different forms of contract partnerships according to the amount of risks transferred to the private sector.Conclusions: Public – private partnerships are neither the only neither the preferred way of providing public service. On one hand they tend to lower financial burden of the public sector but on the other hand PPPs require complex ways of management and monitoring. It is highly important to consider specific circumstances of individual projects in question.

Community-academic research partnerships aim to build stakeholder trust in order to improve the reach and translation of health research, but there is limited empirical research regarding effective ways to build trust. This multisite study was launched to identify similarities and differences among stakeholders' perspectives of antecedents to trust in research partnerships. In 2013-2014, we conducted a mixed-methods concept mapping study with participants from three major stakeholder groups who identified and rated the importance of different antecedents of trust on a 5-point Likert-type scale. Study participants were community members ( n = 66), health care providers ( n = 38), and academic researchers ( n = 44). All stakeholder groups rated "authentic communication" and "reciprocal relationships" the highest in importance. Community members rated "communication/methodology to resolve problems" ( M = 4.23, SD = 0.58) significantly higher than academic researchers ( M = 3.87, SD = 0.67) and health care providers ( M = 3.89, SD = 0.62; p importance of issues related to "sustainability." The importance of communication and relationships across stakeholders indicates the importance of colearning processes that involve the exchange of knowledge and skills. The differences uncovered suggest specific areas where attention and skill building may be needed to improve trust within partnerships. More research on how partnerships can improve communication specific to problem solving and sustainability is merited.

Uddin, Lucina Q; Rayman, Jan; Zaidel, Eran

2005-09-01

To assess the ability of the disconnected cerebral hemispheres to recognize images of the self, a split-brain patient (an individual who underwent complete cerebral commissurotomy to relieve intractable epilepsy) was tested using morphed self-face images presented to one visual hemifield (projecting to one hemisphere) at a time while making "self/other" judgments. The performance of the right and left hemispheres of this patient as assessed by a signal detection method was not significantly different, though a measure of bias did reveal hemispheric differences. The right and left hemispheres of this patient independently and equally possessed the ability to self-recognize, but only the right hemisphere could successfully recognize familiar others. This supports a modular concept of self-recognition and other-recognition, separately present in each cerebral hemisphere.

Middle atmospheric thermal structures in Eastern and Western hemispheres over a solar cycle

Temperature variations of the 25-60 km region of the atmosphere over stations in the Eastern and Western Hemispheres were compared for an 11-year solar cycle period (1971-1981). The temperature of the two hemispheres did not show similar variations at the same height and time. A cross-correlation analysis between the variations in temperature of the two hemispheres showed insignificant correlation, except at 30 km over the tropics and at 40 km over the midlatitude. Up to 40 km, the temperature changes in the two hemispheres are identical. At higher levels, Western Hemispheric temperatures were higher than those of the Eastern Hemisphere. The diurnal variation of minor constituents and their vertical transport in the middle atmosphere might be responsible for the differences in temperature observed in the two hemispheres. (author)

In 2006, the federal government committed funding of $250 million over 5 years for the Canadian Partnership Against Cancer Corporation to begin implementation of the Canadian Strategy for Cancer Control (CSCC). The Partnership was established as a not-for-profit corporation designed to work actively with a broad range of stakeholders and organizations that had been engaged in the development of the CSCC and with the public more broadly. A policy experiment unto itself, the Partnership was the first disease-based organization funded at the federal level outside of government. It was charged with a mandate to enable transfer of knowledge and to catalyze coordinated and accelerated action across the country to reduce the burden of cancer. Implementation has involved establishing shared goals, objectives, and plans with participating partners. Knowledge management-incorporating pan-Canadian approaches to the identification of content, processes, technology, and culture change-was used to enable that work across the federated health care delivery system. Evaluation of the organization through independent review, the ability to achieve initiative-level targets by 2012, and progress measured using indicators of system performance was used to examine the effectiveness of the strategy and approach overall. Evaluation findings support the conclusions that Canada has made progress in achieving immediate outcomes (achievable in 25 years) impact on cancer. The mechanism of funding the Partnership to develop collaboration among stakeholders in cancer control to achieve coordinated action has been possible and has been enabled through the Partnership's knowledge-to-action mandate. Opportunities are available to further engage and clarify the roles of stakeholders in action, to clearly define outcomes, and to further quantify the economic benefits that have resulted from a coordinated approach. With the ongoing funding commitment to support coordinated action within a federated

Asymmetry in intra-hemispheric intrinsic connectivity, and its association with handedness and hemispheric dominance for language, were investigated in a sample of 290 healthy volunteers enriched in left-handers (52.7%). From the resting-state FMRI data of each participant, we derived an intra-hemispheric intrinsic connectivity asymmetry (HICA) matrix as the difference between the left and right intra-hemispheric matrices of intrinsic correlation computed for each pair of the AICHA atlas ROIs. We defined a similarity measure between the HICA matrices of two individuals as the correlation coefficient of their corresponding elements, and computed for each individual an index of intra-hemispheric intrinsic connectivity asymmetry as the average similarity measure of his HICA matrix to those of the other subjects of the sample (HICAs). Gaussian-mixture modeling of the age-corrected HICAs sample distribution revealed that two types of HICA patterns were present, one (Typical_HICA) including 92.4% of the participants while the other (Atypical_HICA) included only 7.6% of them, mostly left-handers. In addition, we investigated the relationship between asymmetry in intra-hemispheric intrinsic connectivity and language hemispheric dominance, including a potential effect of handedness on this relationship, thanks to an FMRI acquisition during language production from which an hemispheric functional lateralization index for language (HFLI) and a type of hemispheric dominance for language, namely leftward, ambilateral, or rightward, were derived for each individual. There was a significant association between the types of language hemispheric dominance and of intra-hemispheric intrinsic connectivity asymmetry, occurrence of Atypical_HICAs individuals being very high in the group of individuals rightward-lateralized for language (80%), reduced in the ambilateral group (19%) and rare in individuals leftward-lateralized for language (less than 3%). Quantitatively, we found a

A hemispherical configuration for scintillation detectors, is introduced so as to minimize the dispersion in light collection by reducing the number of reflexions. Better results in the process of light collection appear explicitly in the gain in the amplitude of the pulse and a better resolution in time and energy when a comparative analysis is made between the cylindrical and hemispherical geometries. The measurements were made using NE102, a plastic scintillator with cylindrical and hemispherical forms, comparing the results of pulse amplitude and energy resolution. The results were quite significant showing a 13% improvement in pulse amplitude and more than 10% in energy resolution for some values of energies from 511 KeV to 1275 KeV. (Author) [pt

The study used topographic brain mapping of visual evoked potentials to investigate emotion-related hemisphere asymmetries. The stimulus material consisted of color photographs of human faces, grouped into two emotion-related categories: normal faces (neutral stimuli) and faces deformed by dermatological diseases (emotional stimuli). The pictures were presented tachistoscopically to 20 adult right-handed subjects. Brain activity was recorded by 30 EEG electrodes with linked ears as reference. The waveforms were averaged separately with respect to each of the two stimulus conditions. Statistical analysis by means of significance probability mapping revealed significant differences between stimulus conditions for two periods of time, indicating right hemisphere superiority in emotion-related processing. The results are discussed in terms of a 2-stage-model of emotional processing in the cerebral hemispheres.

Elements of a strong and healthy interagency partnership

International Nuclear Information System (INIS)

Boucher, Laurel

2013-01-01

In an era of budget cuts and declining resources, an increased need exists for government agencies to develop formal and informal partnerships. Such partnerships are a means through which government agencies can use their resources to accomplish together what they cannot accomplish on their own. Interagency partnerships may involve multiple government agencies, private contractors, national laboratories, technology developers, public representatives, and other stakeholders. Four elements of strong and healthy interagency partnerships are presented as well as three needs that must be satisfied for the partnership to last. A diagnostic tool to measure the strength of these building blocks within an existing partnership is provided. Tools, techniques, and templates to develop these fundamental elements within a new partnership or to strengthen those within an already existing partnership are presented. This includes a comprehensive template for a partnership agreement along with practical suggestions as membership, operations, and decisions-making. (authors)

We have fabricated polycrystalline diamond hemispheres by hot-filament CVD (HFCVD) in spherical cavities wet-etched into a high temperature glass substrate CTE matched to silicon. Hemispherical resonators 1.4 mm in diameter have a Q of up to 143 000 in the fundamental wineglass mode, for a ringdown time of 2.4 s. Without trimming, resonators have the two degenerate wineglass modes frequency matched as close as 2 Hz, or 0.013% of the resonant frequency (∼16 kHz). Laser trimming was used to match resonant modes on hemispheres to 0.3 Hz. Experimental and FEA energy loss studies on cantilevers and hemispheres examine various energy loss mechanisms, showing that surface related losses are dominant. Diamond cantilevers with a Q of 400 000 and a ringdown time of 15.4 s were measured, showing the potential of polycrystalline diamond films for high Q resonators. These resonators show great promise for use as hemispherical resonant gyroscopes (HRGs) on a chip. (paper)

Taxonomic and ad hoc categorization within the two cerebral hemispheres.

Shen, Yeshayahu; Aharoni, Bat-El; Mashal, Nira

2015-01-01

A typicality effect refers to categorization which is performed more quickly or more accurately for typical than for atypical members of a given category. Previous studies reported a typicality effect for category members presented in the left visual field/right hemisphere (RH), suggesting that the RH applies a similarity-based categorization strategy. However, findings regarding the typicality effect within the left hemisphere (LH) are less conclusive. The current study tested the pattern of typicality effects within each hemisphere for both taxonomic and ad hoc categories, using words presented to the left or right visual fields. Experiment 1 tested typical and atypical members of taxonomic categories as well as non-members, and Experiment 2 tested typical and atypical members of ad hoc categories as well as non-members. The results revealed a typicality effect in both hemispheres and in both types of categories. Furthermore, the RH categorized atypical stimuli more accurately than did the LH. Our findings suggest that both hemispheres rely on a similarity-based categorization strategy, but the coarse semantic coding of the RH seems to facilitate the categorization of atypical members.

Emotion-related hemisphere asymmetry: subjective emotional responses to laterally presented films.

Science.gov (United States)

Wittling, W; Roschmann, R

1993-09-01

To investigate whether the cerebral hemispheres differ in their subjective emotional responses 54 adult subjects were presented two films of different emotion-related qualities (positive and negative film) either to their left or right hemisphere. The films were exposed by means of a technique for the lateralization of visual input that allows prolonged viewing while permitting free ocular scanning. Subjective emotional responses were assessed by means of a continuous rating of emotional arousal experienced during the movie as well as by retrospective ratings of ten different emotional qualities. Presenting both films to the right hemisphere resulted in stronger subjective responses in the continuous emotion rating as well as in some retrospectively assessed ratings compared to left-hemispheric presentation. The effects were more pronounced for the negative film. Taken together, the findings suggest a higher responsiveness of the right hemisphere in subjective emotional experience.

Building Sustainable Capacity with University Partnerships

Science.gov (United States)

Harris, J. M.

2013-05-01

Universities can play an important role in building scientific and technical capacity by providing educational opportunities for local and regional populations in developing countries. These opportunities may be short term or long term through for example faculty exchanges, student exchanges, and collaborative teaching and research activities. As the demand for talented graduates expands in developing countries, local universities face competition for students, lecturers, and professors from the same industries and communities they serve. This competition is in many ways counterproductive to building the sustainable human resource that is needed to support local development, management, and governance. Such competition is particularly evident for top science and engineering students in energy rich countries. University partnerships, e.g., in particular those between universities in OECD countries and universities in developing countries, have an important role to play in bridging the gap between today's lack of capacity and a sustainable human resource for the future. Such university partnerships, however, face many challenges, some of which can be traced to organizational and cultural differences In this presentation, I will discuss how university partnerships are formed, some of the benefits to partners, and some pitfalls to avoid during implementation of university partnerships. The examples are taken from Stanford partnerships that involve geoscience and engineering, and will include representative goals and content of the example partnerships. These partnerships I'll describe are actually trilateral, with partners from two or more universities and a private company or government agency. I conclude the presentation with a brief discussion on multiculturalism, perhaps the most important consideration when planning a partnership between diverse organizations. Organizers of partnerships must recognize the fact that multiculturalism and diversity are assets that

2013-01-01

Background: Strong and sustained community–university partnerships are necessary for community-based participatory translational research. Little attention has been paid to understanding the trajectory of research partnerships from a developmental perspective. Objective: To propose a framework describing partnership development and maturation based on Erikson’s eight stages of psychosocial development and describe how our collaboration is moving through those stages. Methods: Collaborators engaged in three rounds of iterative reflection regarding characteristics and contributors to the maturation of the Padres Informados/Jovenes Preparados (Informed Parents/Prepared Youth [PI/JP]) partnership. Lessons Learned: Each stage is characterized by broad developmental partnership tasks. Conflict or tension within the partnership is often a part of achieving the associated tasks. The strengths developed at each stage prepare the partnership for challenges associated with subsequent stages. Conclusions: This framework could provide a means for partnerships to reflect on their strengths and challenges at a given time point, and to help understand why some partnerships fail whereas others achieve maturity.

The Southern Oscillation and northern hemisphere temperature variability

International Nuclear Information System (INIS)

Ropelewski, C.F.; Halpert, M.S.

1990-01-01

The Southern Oscillation (SO) is the best defined and understood mode of interannual climate variability. The extreme phases of the SO have been identified with global-scale variations in the atmosphere/ocean circulation system and with the modulation of monsoon precipitation on the global scale. While SO-related precipitation has been the subject of several studies, the magnitude of the SO-related temperature variability on the global scale has not been well documented. In this paper the authors provide an estimate of the SO-related temperature variability in the context of monitoring global warming related to the increase in greenhouse gases. This analysis suggested that traditional time series of hemispheric and global temperature anomalies for the calendar year may confuse interannual temperature variability associated with the SO and perceived climate trend. Analyses based on calendar-year data are likely to split the effects of the SO-related temperature variability over two years. The Northern Hemisphere cold season (october through March) time series may be more appropriate to separate the SO-related effects on the hemispheric temperature from other modes of variability. mean interannual temperature anomaly differences associated with the extremes of the So are estimated to be 0.2 C for the October-to-March season in the Northern Hemisphere. In areas directly linked to the SO, the mean interannual differences amount to over 0.5 C. The So cannot account for all the variability in the hemispheric times series of surface temperature estimates, but the SO signal must be properly accounted for if these time series are to be understood

Exploring Universal Partnerships and Putative Marriages as Tools for Awarding Partnership Property in Contemporary Family Law

Directory of Open Access Journals (Sweden)

Elsje Bonthuys

2016-12-01

Full Text Available Following upon the Supreme Court of Appeal's judgment in Butters v Mncora 2012 4 SA 1 (SCA, which broadened the criteria and consequences of universal partnerships in cohabitation relationships, this article investigates the potential of universal partnerships and putative marriages to allocate rights to share in partnership property in other intimate relationships. It traverses several instances in which marriages are not recognised - bigamous marriages, Muslim and Hindu religious marriages and invalid customary marriages – examining whether the wives in these marriages could use universal partnerships and putative marriages to claim a share in property. It then considers the use of universal partnerships to obtain a share of property in civil marriages out of community of property. It concludes by pointing out several issues which are in need of clarification and where the common law should be developed to give effect to fundamental constitutional rights.

A group of heterogeneous agents may form partnerships in pairs. All single agents as well as all partnerships generate values. If two agents choose to cooperate, they need to specify how to split their joint value among one another. In equilibrium, which may or may not exist, no agents have incentives to break up or form new partnerships. This paper proposes a dynamic competitive adjustment process that always either finds an equilibrium or exclusively disproves the existence of any equilibri...

Holistic processing has been regarded as a hallmark of face perception, indicating the automatic and obligatory tendency of the visual system to process all face parts as a perceptual unit rather than in isolation. Studies involving lateralized stimulus presentation suggest that the right hemisphere dominates holistic face processing. Holistic processing can also be shown with other categories such as words and thus it is not specific to faces or face-like expertize. Here, we used divided visual field presentation to investigate the possibly different contributions of the two hemispheres for holistic word processing. Observers performed same/different judgment on the cued parts of two sequentially presented words in the complete composite paradigm. Our data indicate a right hemisphere specialization for holistic word processing. Thus, these markers of expert object recognition are domain general.

Motivation and motor control: hemispheric specialization for approach motivation reverses with handedness.

Brookshire, Geoffrey; Casasanto, Daniel

According to decades of research on affective motivation in the human brain, approach motivational states are supported primarily by the left hemisphere and avoidance states by the right hemisphere. The underlying cause of this specialization, however, has remained unknown. Here we conducted a first test of the Sword and Shield Hypothesis (SSH), according to which the hemispheric laterality of affective motivation depends on the laterality of motor control for the dominant hand (i.e., the "sword hand," used preferentially to perform approach actions) and the nondominant hand (i.e., the "shield hand," used preferentially to perform avoidance actions). To determine whether the laterality of approach motivation varies with handedness, we measured alpha-band power (an inverse index of neural activity) in right- and left-handers during resting-state electroencephalography and analyzed hemispheric alpha-power asymmetries as a function of the participants' trait approach motivational tendencies. Stronger approach motivation was associated with more left-hemisphere activity in right-handers, but with more right-hemisphere activity in left-handers. The hemispheric correlates of approach motivation reversed between right- and left-handers, consistent with the way they typically use their dominant and nondominant hands to perform approach and avoidance actions. In both right- and left-handers, approach motivation was lateralized to the same hemisphere that controls the dominant hand. This covariation between neural systems for action and emotion provides initial support for the SSH.

Research on the intimate partnerships of female sex workers (FSWs) tends to focus on the risks associated with these relationships. This paper takes as its starting point that the situation of FSWs is better understood by including knowledge of the benefits of their intimate partnerships. Specifically, we employ the conceptual framework provided by emergent research examining intimacy as a complex fusion of affective and instrumental dimensions among sex workers. This perspective allows us to frame information about FSWs' intimate partnerships within a behaviour-structural approach that is helpful for identifying how intimate partnerships can be a source of both benefit as well as increased risk to FSWs. Our results are based on a mixed-methods study carried out in the summer of 2011 in Kibera, Kenya. We conducted face-to-face interviews (n=30) with a non-probability sample of FSWs stratified by age who self-identified as Human Immune Virus positive (HIV+). We asked about participants' involvement in current and past intimate partnerships, and whether these relationships had a positive or negative impact on their health and well‒being. Participants currently in intimate partnerships had fewer clients and thus lower incomes than those without intimate partnerships. Participants presently with partners were also more likely to receive some financial support from partners, to report lower intimate partner violence, and to narrate higher partner emotional support and greater assistance with medications. These participants were also more likely to have disclosed their sex work and HIV+ statuses to their partners. Intimate partnerships, on the other hand, showed increased risk of economic vulnerability and emotional dependence for FSWs. This became especially problematic for those participants in fragile relationships. Despite these variations, none of the differences between the two groups were statistically significant. Intimacy and transactional relations are bound

Hemispheric differences in the mesostriatal dopaminergic system

2014-06-01

Full Text Available The mesostriatal dopaminergic system, which comprises the mesolimbic and the nigrostriatal pathways, plays a major role in neural processing underlying motor and limbic functions. Multiple reports suggest that these processes are influenced by hemispheric differences in striatal dopamine (DA levels, DA turnover and its receptor activity. Here, we review studies which measured the concentration of DA and its metabolites to examine the relationship between DA imbalance and animal behavior under different conditions. Specifically, we assess evidence in support of endogenous, inter-hemispheric DA imbalance; determine whether the known anatomy provides a suitable substrate for this imbalance; examine the relationship between DA imbalance and animal behavior; and characterize the symmetry of the observed inter-hemispheric laterality in the nigrostriatal and the mesolimbic DA systems. We conclude that many studies provide supporting evidence for the occurrence of experience-dependent endogenous DA imbalance which is controlled by a dedicated regulatory/compensatory mechanism. Additionally, it seems that the link between DA imbalance and animal behavior is better characterized in the nigrostriatal than in the mesolimbic system. Nonetheless, a variety of brain and behavioral manipulations demonstrate that the nigrostriatal system displays symmetrical laterality whereas the mesolimbic system displays asymmetrical laterality which supports hemispheric specialization in rodents. The reciprocity of the relationship between DA imbalance and animal behavior (i.e. the capacity of animal training to alter DA imbalance for prolonged time periods remains controversial, however, if confirmed, may provide a valuable noninvasive therapeutic means for treating abnormal DA imbalance.

Apraxia and spatial inattention dissociate in left hemisphere stroke.

Science.gov (United States)

Timpert, David C; Weiss, Peter H; Vossel, Simone; Dovern, Anna; Fink, Gereon R

2015-10-01

Theories of lateralized cognitive functions propose a dominance of the left hemisphere for motor control and of the right hemisphere for spatial attention. Accordingly, spatial attention deficits (e.g., neglect) are more frequently observed after right-hemispheric stroke, whereas apraxia is a common consequence of left-hemispheric stroke. Clinical reports of spatial attentional deficits after left hemisphere (LH) stroke also exist, but are often neglected. By applying parallel analysis (PA) and voxel-based lesion-symptom mapping (VLSM) to data from a comprehensive neuropsychological assessment of 74 LH stroke patients, we here systematically investigate the relationship between spatial inattention and apraxia and their neural bases. PA revealed that apraxic (and language comprehension) deficits loaded on one common component, while deficits in attention tests were explained by another independent component. Statistical lesion analyses with the individual component scores showed that apraxic (and language comprehension) deficits were significantly associated with lesions of the left superior longitudinal fascicle (SLF). Data suggest that in LH stroke spatial attention deficits dissociate from apraxic (and language comprehension) deficits. These findings contribute to models of lateralised cognitive functions in the human brain. Moreover, our findings strongly suggest that LH stroke patients should be assessed systematically for spatial attention deficits so that these can be included in their rehabilitation regime.

Modeling the Influence of Hemispheric Transport on Trends in ...

Science.gov (United States)

We describe the development and application of the hemispheric version of the CMAQ to examine the influence of long-range pollutant transport on trends in surface level O3 distributions. The WRF-CMAQ model is expanded to hemispheric scales and multi-decadal model simulations were recently performed for the period spanning 1990-2010 to examine changes in hemispheric air pollution resulting from changes in emissions over this period. Simulated trends in ozone and precursor species concentrations across the U.S. and the northern hemisphere over the past two decades are compared with those inferred from available measurements during this period. Additionally, the decoupled direct method (DDM) in CMAQ is used to estimate the sensitivity of O3 to emissions from different source regions across the northern hemisphere. The seasonal variations in source region contributions to background O3 is then estimated from these sensitivity calculations and will be discussed. A reduced form model combining these source region sensitivities estimated from DDM with the multi-decadal simulations of O3 distributions and emissions trends, is then developed to characterize the changing contributions of different source regions to background O3 levels across North America. The National Exposure Research Laboratory (NERL) Computational Exposure Division (CED) develops and evaluates data, decision-support tools, and models to be applied to media-specific or receptor-specific problem areas

Full Text Available In the present study we investigate hemispheric processing of conventional and unconventional visual stimuli in the context of visual and verbal creative ability. In Experiment 1, we studied two unconventional visual recognition tasks – Mooney face and objects' silhouette recognition – and found a significant relationship between measures of verbal creativity and unconventional face recognition. In Experiment 2 we used the split visual field paradigm to investigate hemispheric processing of conventional and unconventional faces and its relation to verbal and visual characteristics of creativity. Results showed that while conventional faces were better processed by the specialized right hemisphere, unconventional faces were better processed by the non-specialized left hemisphere. In addition, only unconventional face processing by the non-specialized left hemisphere was related to verbal and visual measures of creative ability. Our findings demonstrate the role of the non-specialized hemisphere in processing unconventional stimuli and how it relates to creativity.

Hemispherically asymmetric trade wind changes as signatures of past ITCZ shifts

Science.gov (United States)

McGee, David; Moreno-Chamarro, Eduardo; Green, Brian; Marshall, John; Galbraith, Eric; Bradtmiller, Louisa

2018-01-01

The atmospheric Hadley cells, which meet at the Intertropical Convergence Zone (ITCZ), play critical roles in transporting heat, driving ocean circulation and supplying precipitation to the most heavily populated regions of the globe. Paleo-reconstructions can provide concrete evidence of how these major features of the atmospheric circulation can change in response to climate perturbations. While most such reconstructions have focused on ITCZ-related rainfall, here we show that trade wind proxies can document dynamical aspects of meridional ITCZ shifts. Theoretical expectations based on angular momentum constraints and results from freshwater hosing simulations with two different climate models predict that ITCZ shifts due to anomalous cooling of one hemisphere would be accompanied by a strengthening of the Hadley cell and trade winds in the colder hemisphere, with an opposite response in the warmer hemisphere. This expectation of hemispherically asymmetric trade wind changes is confirmed by proxy data of coastal upwelling and windblown dust from the Atlantic basin during Heinrich stadials, showing trade wind strengthening in the Northern Hemisphere and weakening in the Southern Hemisphere subtropics in concert with southward ITCZ shifts. Data from other basins show broadly similar patterns, though improved constraints on past trade wind changes are needed outside the Atlantic Basin. The asymmetric trade wind changes identified here suggest that ITCZ shifts are also marked by intensification of the ocean's wind-driven subtropical cells in the cooler hemisphere and a weakening in the warmer hemisphere, which induces cross-equatorial oceanic heat transport into the colder hemisphere. This response would be expected to prevent extreme meridional ITCZ shifts in response to asymmetric heating or cooling. Understanding trade wind changes and their coupling to cross-equatorial ocean cells is key to better constraining ITCZ shifts and ocean and atmosphere dynamical

The Integrated Landscape Modeling partnership - Current status and future directions

2016-01-28

The Integrated Landscape Modeling (ILM) partnership is an effort by the U.S. Geological Survey (USGS) and U.S. Department of Agriculture (USDA) to identify, evaluate, and develop models to quantify services derived from ecosystems, with a focus on wetland ecosystems and conservation effects. The ILM partnership uses the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) modeling platform to facilitate regional quantifications of ecosystem services under various scenarios of land-cover change that are representative of differing conservation program and practice implementation scenarios. To date, the ILM InVEST partnership has resulted in capabilities to quantify carbon stores, amphibian habitat, plant-community diversity, and pollination services. Work to include waterfowl and grassland bird habitat quality is in progress. Initial InVEST modeling has been focused on the Prairie Pothole Region (PPR) of the United States; future efforts might encompass other regions as data availability and knowledge increase as to how functions affecting ecosystem services differ among regions.The ILM partnership is also developing the capability for field-scale process-based modeling of depressional wetland ecosystems using the Agricultural Policy/Environmental Extender (APEX) model. Progress was made towards the development of techniques to use the APEX model for closed-basin depressional wetlands of the PPR, in addition to the open systems that the model was originally designed to simulate. The ILM partnership has matured to the stage where effects of conservation programs and practices on multiple ecosystem services can now be simulated in selected areas. Future work might include the continued development of modeling capabilities, as well as development and evaluation of differing conservation program and practice scenarios of interest to partner agencies including the USDA’s Farm Service Agency (FSA) and Natural Resources Conservation Service (NRCS).

Acquired dysgraphia in adults following right or left-hemisphere stroke

Directory of Open Access Journals (Sweden)

Jaqueline de Carvalho Rodrigues

Full Text Available OBJECTIVE: This study aimed to assess the strengths and difficulties in word and pseudoword writing in adults with left- and right-hemisphere strokes, and discuss the profiles of acquired dysgraphia in these individuals.METHODS: The profiles of six adults with acquired dysgraphia in left- or right-hemisphere strokes were investigated by comparing their performance on word and pseudoword writing tasks against that of neurologically healthy adults. A case series analysis was performed on the patients whose impairments on the task were indicative of acquired dysgraphia.RESULTS: Two patients were diagnosed with lexical dysgraphia (one with left hemisphere damage, and the other with right hemisphere damage, one with phonological dysgraphia, another patient with peripheral dysgraphia, one patient with mixed dysgraphia and the last with dysgraphia due to damage to the graphemic buffer. The latter patients all had left-hemisphere damage (LHD. The patterns of impairment observed in each patient were discussed based on the dual-route model of writing.CONCLUSION: The fact that most patients had LHD rather than right-hemisphere damage (RHD highlights the importance of the former structure for word processing. However, the fact that lexical dysgraphia was also diagnosed in a patient with RHD suggests that these individuals may develop writing impairments due to damage to the lexical route, leading to heavier reliance on phonological processing. Our results are of significant importance to the planning of writing interventions in neuropsychology.

Goal four is met by ongoing meetings through-out the school year, classroom visits by YSU faculty and fieldtrips to the YSU Campus by classes led by OPFERST teachers. Evaluation of OPFERST includes demographic and classroom practice data, pre- and post-tests of participants, journals, homework and the administration of evaluation instruments with some OPFERST participants' students.

Reading the Wrong Way with the Right Hemisphere

Full Text Available Reading is a complex process, drawing on a variety of brain functions in order to link symbols to words and concepts. The three major brain areas linked to reading and phonological analysis include the left temporoparietal region, the left occipitotemporal region and the inferior frontal gyrus. Decreased activation of the left posterior language system in dyslexia is well documented but there is relatively limited attention given to the role of the right hemisphere. The current study investigated differences in right and left hemisphere activation between individuals with dyslexia and non-impaired readers in lexical decision tasks (regular words, irregular words, pseudowords during functional Magnetic Resonance Imaging (fMRI. Results revealed the expected hypo-activation in the left posterior areas in those with dyslexia but also areas of overactivation in the right hemisphere. During pseudoword decisions, for example, adults with dyslexia showed more right inferior occipital gyrus activation than controls. In general the increased activation of left-hemisphere language areas found in response to both regular and pseudowords was absent in dyslexics. Laterality indices showed that while controls showed left lateralised activation of the temporal lobe during lexical decision making, dyslexic readers showed right activation. Findings will inform theories of reading and will have implications for the design of reading interventions.

Wave-current generated turbulence over hemisphere bottom roughness

2018-03-01

The present paper explores the effect of wave-current interaction on the turbulence characteristics and the distribution of eddy structure over artificially crammed rough bed prepared with hemispheres. The effect of the surface wave on temporal and spatial-averaged mean velocity, intensity, Reynolds shear stress over, within cavity and above the hemispherical bed are discussed. Detailed three-dimensional time series velocity components were measured in a tilting flume using 3-D Micro-Acoustic Doppler Velocimeter (ADV) at a Reynolds number, 62 × 103. This study reports the fractional contributions of burst-sweep cycles dominating the total shear stress near hemispherical rough surface both for current only flow as well as for wave-induced cases. Wavelet analysis of the fluctuating velocity signal shows that the superimposed wave of frequency 1 Hz is capable of modulating the energy containing a range of velocity fluctuations at the mid-depth of the cavity region (formed due to the crammed arrangement of the hemispheres). As a result, the large-scale eddies (with large values of wavelet coefficients) are concentrated at a pseudo-frequency which is equal to the wave oscillating frequency. On the other hand, it is observed that the higher wave frequency (2 Hz) is incapable of modulating the eddy structures at that particular region.

Mapping hemispheric symmetries, relative asymmetries, and absolute asymmetries underlying the auditory laterality effect.

Functional hemispheric differences for speech and language processing have been traditionally studied by using verbal dichotic-listening paradigms. The commonly observed right-ear preference for the report of dichotically presented syllables is taken to reflect the left hemispheric dominance for speech processing. However, the results of recent functional imaging studies also show that both hemispheres - not only the left - are engaged by dichotic listening, suggesting a more complex relationship between behavioral laterality and functional hemispheric activation asymmetries. In order to more closely examine the hemispheric differences underlying dichotic-listening performance, we report an analysis of functional magnetic resonance imaging (fMRI) data of 104 right-handed subjects, for the first time combining an interhemispheric difference and conjunction analysis. This approach allowed for a distinction of homotopic brain regions which showed symmetrical (i.e., brain region significantly activated in both hemispheres and no activation difference between the hemispheres), relative asymmetrical (i.e., activated in both hemispheres but significantly stronger in one than the other hemisphere), and absolute asymmetrical activation patterns (i.e., activated only in one hemisphere and this activation is significantly stronger than in the other hemisphere). Symmetrical activation was found in large clusters encompassing temporal, parietal, inferior frontal, and medial superior frontal regions. Relative and absolute left-ward asymmetries were found in the posterior superior temporal gyrus, located adjacent to symmetrically activated areas, and creating a lateral-medial gradient from symmetrical towards absolute asymmetrical activation within the peri-Sylvian region. Absolute leftward asymmetry was also found in the post-central and medial superior frontal gyri, while rightward asymmetries were found in middle temporal and middle frontal gyri. We conclude that dichotic

2007-01-01

Nuclear knowledge is characterized by high-complexity and variety of the component topics and long duration required by the build-up of individual competence. At organizational level, these characteristics made the power of an organization or institution to be determined by the capital accumulated of existing knowledge. Furthermore, the capacity of an organization to re-generate and raise the knowledge capital according to the specific processes it is running according to the existing demand decides its position/ranking in the economy of nuclear field. Knowledge management emphasizes re-utilization of existing practice and experience, upgrade, enrich and re-value of accumulated knowledge. The present paper identifies and classifies the nuclear knowledge steps, namely: tacit knowledge, explicit knowledge, preserving, transfer, knowledge capture etc. On this basis there are identified the existing problems of nuclear knowledge management in Romania such as: difficulties to keep within the country the existing expertise, lack of interest in nuclear education, low level of organization of existing knowledge due to a small number of data bases, an insufficient integration of existing knowledge in IT systems, lack of ontology and taxonomy or an average structuralism. Nuclear knowledge in Romania is facing a major challenge which is generated by the future development of nuclear facilities. It is related to the rising demand of expertise and experts. This challenge is better solved by partnership between end users and institutions of Research and Development and university organization as well which could ensure the generation, transfer and preservation of nuclear knowledge.

Mercury is a toxic element of serious concern for human and environmental health. Understanding its natural cycling in the environment is an important goal towards assessing its impacts and the effectiveness of mitigation strategies. Due to the unique chemical and physical properties of mercury, the atmosphere is the dominant transport pathway for this heavy metal, with the consequence that regions far removed from sources can be impacted. However, there exists a dearth of long-term monitoring of atmospheric mercury, particularly in the tropics and Southern Hemisphere. This paper presents the first 2 years of gaseous elemental mercury (GEM) measurements taken at the Australian Tropical Atmospheric Research Station (ATARS) in northern Australia, as part of the Global Mercury Observation System (GMOS). Annual mean GEM concentrations determined at ATARS (0.95 ± 0.12 ng m-3) are consistent with recent observations at other sites in the Southern Hemisphere. Comparison with GEM data from other Australian monitoring sites suggests a concentration gradient that decreases with increasing latitude. Seasonal analysis shows that GEM concentrations at ATARS are significantly lower in the distinct wet monsoon season than in the dry season. This result provides insight into alterations of natural mercury cycling processes as a result of changes in atmospheric humidity, oceanic/terrestrial fetch, and convective mixing, and invites future investigation using wet mercury deposition measurements. Due to its location relative to the atmospheric equator, ATARS intermittently samples air originating from the Northern Hemisphere, allowing an opportunity to gain greater understanding of inter-hemispheric transport of mercury and other atmospheric species. Diurnal cycles of GEM at ATARS show distinct nocturnal depletion events that are attributed to dry deposition under stable boundary layer conditions. These cycles provide strong further evidence supportive of a multi-hop model of GEM

Background Understanding of interhemispheric interactions in stroke patients during motor control is an important clinical neuroscience quest that may provide important clues for neurorehabilitation. In stroke patients bilateral overactivation in both hemispheres has been interpreted as a poor prognostic indicator of functional recovery. In contrast, ipsilesional patterns have been linked with better motor outcomes. Aim We investigated the pathophysiology of hemispheric interactions during limb movement without and with contralateral restraint, to mimic the effects of constraint-induced movement therapy. We used neuroimaging to probe brain activity with such a movement-dependent interhemispheric modulation paradigm. Methods We used a functional magnetic resonance imaging block design during which the plegic/paretic upper limb was recruited/mobilized to perform unilateral arm elevation, as a function of presence versus absence of contralateral limb restriction (n = 20, with balanced left/right lesion sites). Results Analysis of 10 right hemispheric stroke participants yielded bilateral sensorimotor cortex activation in all movement phases in contrast with the unilateral dominance seen in the 10 left hemispheric stroke participants. Superimposition of contralateral restriction led to a prominent shift from activation to deactivation response patterns, in particular in cortical and basal ganglia motor areas in right hemispheric stroke. Left hemispheric stroke was, in general, characterized by reduced activation patterns, even in the absence of restriction, which induced additional cortical silencing. Conclusion The observed hemispheric-dependent activation/deactivation shifts is novel and these pathophysiological observations suggest short-term neuroplasticity that may be useful for hemisphere-tailored neurorehabilitation.

The effect of dual-hemisphere breeding on stallion fertility.

Walbornn, S R; Love, C C; Blanchard, T L; Brinsko, S P; Varner, D D

2017-05-01

Breeding records were analyzed from 24 Thoroughbred stallions that were subjected to dual-hemisphere breeding (DH), including novice (first-year; NOV; n = 11) and experienced (EXP; n = 13) stallions. Fertility variables included seasonal pregnancy rate, pregnancy rate per cycle, and first-cycle pregnancy rate. In addition, values for book size, total number of covers, distribution of mare type (maiden, foaling, and barren) within a stallion's book, cycles per mare, and mare age were examined. Some data were also categorized by mare type (maiden-M, foaling-F, and barren-B). Five separate analyses of the data were performed. For Analyses 1-3, the effects of hemisphere (northern hemisphere [NH] vs. southern hemisphere [SH]) and breeding order (refers to the first [O1] or second [O2] season within the first year of dual-hemisphere breeding) were examined for all stallions (combined group [CG]), NOV stallions only, and EXP stallions only, respectively. Fertility values were generally higher in the SH than the NH (P fertility of O1 was generally similar to O2 (P > 0.05). For Analysis 4, fertility of DH breeding seasons was compared to single hemisphere (SIN) breeding seasons within the same 16 stallions and was found to be similar between the two groups (P > 0.05). For Analysis 5, the effect of the number of consecutive DH breeding seasons on fertility was examined and was found to remain unchanged (P > 0.05). In summary, no adverse effects of DH breeding on fertility were detected. Fertility was higher when stallions were bred in the SH, as compared to the NH. Potential reasons for higher fertility achieved in the SH were smaller book sizes and better mare reproductive quality. Copyright © 2017. Published by Elsevier Inc.

Callosal tracts and patterns of hemispheric dominance: a combined fMRI and DTI study.

Häberling, Isabelle S; Badzakova-Trajkov, Gjurgjica; Corballis, Michael C

2011-01-15

Left-hemispheric dominance for language and right-hemispheric dominance for spatial processing are distinctive characteristics of the human brain. However, variations of these hemispheric asymmetries have been observed, with a minority showing crowding of both functions to the same hemisphere or even a mirror reversal of the typical lateralization pattern. Here, we used diffusion tensor imaging and functional magnetic imaging to investigate the role of the corpus callosum in participants with atypical hemispheric dominance. The corpus callosum was segmented according to the projection site of the underlying fibre tracts. Analyses of the microstructure of the identified callosal segments revealed that atypical hemispheric dominance for language was associated with high anisotropic diffusion through the corpus callosum as a whole. This effect was most evident in participants with crowding of both functions to the right. The enhanced anisotropic diffusion in atypical hemispheric dominance implies that in these individuals the two hemispheres are more heavily interconnected. Copyright © 2010 Elsevier Inc.

Samuel, Peter

2013-01-01

The purpose of this book is to evaluate the debate on partnership, using original research data. Samuel provides a novel categorisation with which to synthesise and clarify a highly diverse literature on labour-management partnership, thus helping to refine the contemporary partnership debate. Secondly, he clarifies the circumstances under which 'effective' labour-management partnership is possible, while simultaneously elaborating why the achievement of 'mutual gains' is highly improbable in a liberal-market context. Thirdly, the book presents an integrated analysis of the interplay between macro-, meso- (industry) and micro-level factors. Fourthly, the research design enables the study to go beyond the case studies to make defendable empirical generalizations at the level of the industry. Finally, it advances a theoretical explanation of labour-management partnerships in 'liberal market' economies by bridging two opposing neo-institutional positions in the social sciences.

Stuttering is a complex speech disorder. Previous studies indicate a tendency towards elevated motor threshold for the left hemisphere, as measured using transcranial magnetic stimulation (TMS). This may reflect a monohemispheric motor system impairment. The purpose of the study was to investigate the relative side-to-side difference (asymmetry) and the absolute levels of motor threshold for the hand area, using TMS in adults who stutter (n = 15) and in controls (n = 15). In accordance with the hypothesis, the groups differed significantly regarding the relative side-to-side difference of finger motor threshold (p = 0.0026), with the stuttering group showing higher motor threshold of the left hemisphere in relation to the right. Also the absolute level of the finger motor threshold for the left hemisphere differed between the groups (p = 0.049). The obtained results, together with previous investigations, provide support for the hypothesis that stuttering tends to be related to left hemisphere motor impairment, and possibly to a dysfunctional state of bilateral speech motor control.

2012-01-01

Following the '911' attack on the USA in 2001 the international community under Canada's G8 leadership established a $20 billion Global Partnership initiative in 2002 to collaboratively address threats to global security posed by the proliferation and potential terrorist use of Weapons and Materials of Mass Destruction (WMMD) and related materials and knowledge. This major international initiative addressed four priority areas: (1) Chemical Weapon Destruction (2) Nuclear powered submarine eliminations (3) Nuclear and radiological security; and (4) Employment for former weapon scientists. Additionally the initiative has addressed Biological Non- Proliferation. Canada's execution of all these program areas has resulted in substantial environmental benefits aside from the eradication and securing of WMMD. This paper reviews the environmental and radiological remediation achievements of the four primary Global Partnership program areas addressed under Canadian funding 2004 through 2011. (author)

Trends in Northern Hemisphere surface cyclone frequency and intensity

McCabe, G.J.; Clark, M.P.; Serreze, Mark C.

2001-01-01

One of the hypothesized effects of global warming from increasing concentrations of greenhouse gases is a change in the frequency and/or intensity of extratropical cyclones. In this study, winter frequencies and intensities of extratropical cyclones in the Northern Hemisphere for the period 1959-97 are examined to determine if identifiable trends are occurring. Results indicate a statistically significant decrease in midlatitude cyclone frequency and a significant increase in high-latitude cyclone frequency. In addition, storm intensity has increased in both the high and midlatitudes. The changes in storm frequency correlate with changes in winter Northern Hemisphere temperature and support hypotheses that global warming may result in a northward shift of storm tracks in the Northern Hemisphere.

The outcomes of partnerships with mental health service users in interprofessional education: a case study.

Barnes, Di; Carpenter, John; Dickinson, Claire

2006-09-01

This paper reports findings from a 5-year evaluation (1998-2003) of a postqualifying programme in community mental health in England which made a sustained attempt to develop partnerships with service users. Users were involved in the commissioning of the programme and its evaluation, as trainers and as course members. The evaluation employed mixed methods to assess: learners' reactions to user-trainers and users as course members; changes in knowledge, attitudes and skills; and changes in individual and organisational practice. Data were collected from participant observation of training, 23 individual and 18 group interviews with students and their managers (n=13), and student ratings of knowledge and skills at the beginning and end of the programme (n=49). The quality of care provided by students was rated by service users (n=120) with whom they worked, using a user-defined questionnaire. The quality of care, and mental health and quality of life outcomes were compared to those for two comparison groups (n=44) in areas where no training had taken place. In general, the students reported positive learning outcomes associated with the partnership orientation of the programme, and learning directly from and with service users. A higher proportion of programme users reported good user-centred assessment and care planning, and showed greater improvement in life skills compared to the comparators. This case study provides evidence of the value of partnership working with service users in interprofessional postqualifying education in mental health. The success is attributed to the design of the programme and the responsiveness of the programme board, which included service users. It may provide a useful model for programmes elsewhere and for other user groups. The case study itself provides a possible model for the systematic evaluation of partnerships with users in education and training.

Studies with diffusion tensor imaging (DTI) analysis have produced conflicting information about the involvement of the cerebellar hemispheres in Parkinson's disease (PD). We, thus, used a new approach for the analysis of DTI parameters in order to ascertain the involvement of the cerebellum in PD. We performed a fiber tract-based analysis of cerebellar peduncles and cerebellar hemispheres in 16 healthy subjects and in 16 PD patients with more than 5 years duration of disease, using a 3T MRI scanner and a constrained spherical deconvolution (CSD) approach for tractographic reconstructions. In addition, we performed statistical analysis of DTI parameters and fractional anisotropy (FA) XYZ direction samplings. We found a statistically significant decrement of FA values in PD patients compared to controls (p < 0.05). In addition, extrapolating and analyzing FA XYZ direction samplings for each patient and each control, we found that this result was due to a stronger decrement of FA values along the Y axis (antero-posterior direction) (p < 0.01); FA changes along X and Z axes were not statistically significant (p > 0.05). We confirmed also no statistically significant differences of FA and apparent diffusion coefficient (ADC) for cerebellar peduncles in PD patients compared to healthy controls. The DTI-based cerebellar abnormalities in PD could constitute an advance in the knowledge of this disease. We demonstrated a statistically significant reduction of FA in cerebellar hemispheres of PD patients compared to healthy controls. Our work also demonstrated that the use of more sophisticated approaches in the DTI parameter analysis could potentially have a clinical relevance. (orig.)

Fu, Yu; McNichol, Elaine; Marczewski, Kathryn; Closs, S José

2016-05-01

Chronic back pain is common, and its self-management may be a lifelong task for many patients. While health professionals can provide a service or support for pain, only patients can actually experience it. It is likely that optimum self-management of chronic back pain may only be achieved when patients and professionals develop effective partnerships which integrate their complementary knowledge and skills. However, at present, there is no evidence to explain how such partnerships can influence patients' self-management ability. This review aimed to explore the influence of patient-professional partnerships on patients' ability to self-manage chronic back pain, and to identify key factors within these partnerships that may influence self-management. A systematic review was undertaken, aiming to retrieve relevant studies using any research method. Five databases were searched for papers published between 1980 and 2014, including Cochrane Library, CINAHL, Medline, EMBASE and PsycINFO. Eligible studies were those reporting on patients being supported by professionals to self-manage chronic back pain; patients being actively involved for self-managing chronic back pain; and the influence of patient-professional partnerships on self-management of chronic back pain. Included studies were critically appraised for quality, and findings were extracted and analysed thematically. A total of 738 studies were screened, producing 10 studies for inclusion, all of which happened to use qualitative methods. Seven themes were identified: communication, mutual understanding, roles of health professionals, information delivery, patients' involvement, individualised care and healthcare service. These themes were developed into a model suggesting how factors within patient-professional partnerships influence self-management. Review findings suggest that a partnership between patients and professionals supports patients' self-management ability, and effective communication is a

An overview of Fukushima radionuclides measured in the northern hemisphere

The Great East Japan Earthquake and tsunami on March 11, 2011 resulted in the tragic accident at the Fukushima Nuclear Power Plant (NPP) and subsequently uncontrolled release of radioactive contaminants into the atmosphere. This review article attempts to compile and interpret data collected by various national and international monitoring networks in response to the Fukushima releases across the northern hemisphere. The majority of the releases occurred during the period March 12–22 with a maximum release phase from March 14–17, 2011. The radioactivity released was dominated by volatile fission products including isotopes of the noble gases (xenon and krypton), iodine, cesium, and tellurium. The radioactive gases and particles released in the accident were dispersed over the middle latitudes of the entire northern hemisphere and for the first time also measured in the southern Hemisphere. Isotopes of iodine and cesium were detected in air, water, milk and food samples collected across the entire northern hemisphere. Elevated levels of fission products were detected from March to May 2011 at many locations over the northern hemisphere. This article focuses on the most prevalent cesium and iodine isotopes, but other secondary isotopes are also discussed. Spatial and temporal patterns and differences are contrasted. The activity ratios of 131 I/ 137 Cs and 134 Cs/ 137 Cs measured at several locations are evaluated to gain an insight into the fuel burn-up, the inventory of radionuclides in the reactor and the isotopic signature of the accident. It is important to note that all of the radiation levels detected outside of Japan have been very low and are well below any level of public and environmental hazard. - Graphical abstract: The trace levels of radioactivity in air, water, and milk samples collected across the northern hemisphere between March–May, 2011 from the damaged Fukushima Daiichi nuclear power plant, Japan are discussed.

Speech processing: from peripheral to hemispheric asymmetry of the auditory system.

Science.gov (United States)

Lazard, Diane S; Collette, Jean-Louis; Perrot, Xavier

2012-01-01

Language processing from the cochlea to auditory association cortices shows side-dependent specificities with an apparent left hemispheric dominance. The aim of this article was to propose to nonspeech specialists a didactic review of two complementary theories about hemispheric asymmetry in speech processing. Starting from anatomico-physiological and clinical observations of auditory asymmetry and interhemispheric connections, this review then exposes behavioral (dichotic listening paradigm) as well as functional (functional magnetic resonance imaging and positron emission tomography) experiments that assessed hemispheric specialization for speech processing. Even though speech at an early phonological level is regarded as being processed bilaterally, a left-hemispheric dominance exists for higher-level processing. This asymmetry may arise from a segregation of the speech signal, broken apart within nonprimary auditory areas in two distinct temporal integration windows--a fast one on the left and a slower one on the right--modeled through the asymmetric sampling in time theory or a spectro-temporal trade-off, with a higher temporal resolution in the left hemisphere and a higher spectral resolution in the right hemisphere, modeled through the spectral/temporal resolution trade-off theory. Both theories deal with the concept that lower-order tuning principles for acoustic signal might drive higher-order organization for speech processing. However, the precise nature, mechanisms, and origin of speech processing asymmetry are still being debated. Finally, an example of hemispheric asymmetry alteration, which has direct clinical implications, is given through the case of auditory aging that mixes peripheral disorder and modifications of central processing.

We report the indications and outcomes of awake right hemispheric brain surgery, as well as a rare patient with crossed aphasia. Awake craniotomies are often performed to protect eloquent cortex. We reviewed the medical records for 35 of 96 patients, in detail, who had awake right hemisphere brain operations. Intraoperative cortical mapping of motor and/or language function was performed in 29 of the 35 patients. A preoperative speech impairment and left hand dominance were the main indicators for awake right-sided craniotomies in patients with right hemisphere lesions. Four patients with lesion proximity to eloquent areas underwent awake craniotomies without cortical mapping. In addition, one patient had a broncho-pulmonary fistula, and another had a recent major cardiac procedure that precluded awake surgery. An eloquent cortex representation was identified in 14 patients (48.3%). Postoperatively, seven of 17 patients (41.1%) who presented with weakness, experienced improvements in their motor functions, 11 of 16 (68.7%) with seizures became seizure-free, and seven of nine (77.7%) with moderate to severe headaches and one of two with a visual field deficit improved significantly. There were also improvements in speech and language functions in all patients who presented with speech difficulties. A right sided awake craniotomy is an excellent option for left handed patients, or those with right sided cortical lesions that result in preoperative speech impairments. When combined with intraoperative cortical mapping, both speech and motor function can be well preserved. Copyright © 2015 Elsevier Ltd. All rights reserved.

The Southwest Partnership Region includes six whole states, including Arizona, Colorado, Kansas, New Mexico, Oklahoma, and Utah, roughly one-third of Texas, and significant portions of adjacent states. The Partnership comprises a large, diverse group of expert organizations and individuals specializing in carbon sequestration science and engineering, as well as public policy and outreach. The main objective of the Southwest Partnership project is to achieve an 18% reduction in carbon intensity by 2012. The Partnership made great progress in this first year. Action plans for possible Phase II carbon sequestration pilot tests in the region are almost finished, including both technical and non-technical aspects necessary for developing and carrying out these pilot tests. All partners in the Partnership are taking an active role in evaluating and ranking optimum sites and technologies for capture and storage of CO{sub 2} in the Southwest Region. We are identifying potential gaps in all aspects of potential sequestration deployment issues.

The clinical partnership as strategic alliance.

Novotny, Jeanne M; Donahue, Moreen; Bhalla, Bharat B

2004-01-01

The purpose of this article is to describe a renewed partnership between a collegiate school of nursing and a community hospital. Universities and hospitals are searching for creative solutions to increase the number of registered nurses available to meet the demand for nursing care. An affiliation agreement had been in existence for many years, but health care system imperatives made it necessary to redesign the partnership between nursing education and nursing service. The model used to develop this new partnership is based on the work done in the field of management and is in the form of a strategic alliance. The success of a strategic alliance depends on two key factors: the relationship between partners and partnership performance. Identified outcomes show that this partnership is helping to meet the increasing demand for nursing care by building student capacity, satisfying mutual needs of faculty and clinical staff, and removing economic barriers. This article describes the development of the strategic alliance, its current status, and strategies for the future.

Experiments were conducted on heat transfer from internally heated ZnSO 4 -H 2 O pools to the walls of hemispherical containers. This experimental technique provides data for a heat transfer system that has to date been only theoretically treated. Three different sizes of copper hemispherical containers were used: 240, 280, 320 mm in diameter. The pool container served both as a heat transfer surface and as an electrode. The opposing electrode was a copper disk, 50 mm in diameter located at the top of the pool in the center. The top surface of the pool was open to the atmosphere

Caffeine improves left hemisphere processing of positive words.

Science.gov (United States)

Kuchinke, Lars; Lux, Vanessa

2012-01-01

A positivity advantage is known in emotional word recognition in that positive words are consistently processed faster and with fewer errors compared to emotionally neutral words. A similar advantage is not evident for negative words. Results of divided visual field studies, where stimuli are presented in either the left or right visual field and are initially processed by the contra-lateral brain hemisphere, point to a specificity of the language-dominant left hemisphere. The present study examined this effect by showing that the intake of caffeine further enhanced the recognition performance of positive, but not negative or neutral stimuli compared to a placebo control group. Because this effect was only present in the right visual field/left hemisphere condition, and based on the close link between caffeine intake and dopaminergic transmission, this result points to a dopaminergic explanation of the positivity advantage in emotional word recognition.

The experience with cortical localization (BA 44, 45, 22) of language (Broca, Wernicke and others) in the left hemisphere has been repeatedly tested over the last 150 years and is now generally accepted. A single case report with autopsy findings (Leborgne, Tan tan), has enabled to localize the seat of spoken language in the left third frontal convolution. As music and language have a lot in common and even share the same hearing system, it is logical to try to localize the cognitive centers for music too. The disabling neurological disease illness of Maurice Ravel (1875-1937), a French impressionist composer, is not the right example to localize music center as that of Broca's language center, but it demonstrates the role of the right hemisphere in music production. In the last five years of his life, Ravel suffered from an unknown disease that affected the left hemisphere causing aphasia, apraxia, alexia, agraphia and amusia. It was the reason why Ravel could not compose during the last years of his life. In contrast to Ravel, Shebalin and Britten continued writing music works of their own although aphasic after having sustained two strokes to the left hemisphere. While lacking clinical cases with selective ablative brain lesions, research into the music localization can be done using modern imaging technologies such as fMRI and PET. Exercising music (professionally) develops analytical process in the left hemisphere whereas other individuals process music in their right hemisphere. There is right ear (left hemisphere) predominance in musicians and vice versa in musical amateurs. Music lateralization towards the right hemisphere is seen in women and in inattentive listeners. It can be subject to cultural influence, so the Japanese process their traditional popular music in the left hemisphere, whereas Westerners process the same music in the right hemisphere. Music and language are processed separately; they are localized in homologous regions of the opposite

Radioiodine (131I) in animal thyroids during nuclear tests in both hemispheres

Van Middlesworth, L.

1975-01-01

In mid-1974 a small increase of 131 I was observed in animal thyroids following a nuclear test in China. In late 1974 there was no public announcement of an atmospheric nuclear test in the Northern Hemisphere, but 131 I was readily measured in animal thyroids. This latter increase occurred while animals in the Southern Hemisphere accumulated 131 I from nuclear tests in the Southern Hemisphere. It is suggested that in late 1974 the Northern Hemisphere was contaminated by either late fallout from tests in June or by interhemispheric mixing or by a combination of these sources. (author)

Developing Partnerships between Higher Education Faculty, K-12 Science Teachers, and School Administrators via MSP initiatives: The RITES Model

Science.gov (United States)

Caulkins, J. L.; Kortz, K. M.; Murray, D. P.

2011-12-01

The Rhode Island Technology Enhanced Science Project (RITES) is a NSF-funded Math and Science Partnership (MSP) project that seeks to improve science education. RITES is, at its core, a unique partnership that fosters relationships between middle and high school science teachers, district and school administrators, higher education (HE) faculty members, and science education researchers. Their common goal is to enhance scientific inquiry, increase classroom technology usage, and improve state level science test scores. In one of the more visible examples of this partnership, middle and high school science teachers work closely with HE science faculty partners to design and teach professional development (PD) workshops. The PD sessions focus on technology-enhanced scientific investigations (e.g. use of probes, online simulations, etc.), exemplify inquiry-based instruction, and relate expert content knowledge. Teachers from these sessions express substantial satisfaction in the program, report increased comfort levels in teaching the presented materials (both via post-workshop surveys), and show significant gains in content knowledge (via pre-post assessments). Other benefits to this kind of partnership, in which K-12 and HE teachers are considered equals, include: 1) K-12 teachers are empowered through interactions with HE faculty and other science teachers in the state; 2) HE instructors become more informed not only about good pedagogical practices, but also practical aspects of teaching science such as engaging students; and 3) the PD sessions tend to be much stronger than ones designed and presented solely by HE scientists, for while HE instructors provide content expertise, K-12 teachers provide expertise in K-12 classroom practice and implementation. Lastly, the partnership is mutually beneficial for the partners involved because both sides learn practical ways to teach science and inquiry at different levels. In addition to HE faculty and K-12 science teacher

Cardiac asystole associated with seizures of right hemispheric onset

Full Text Available Ictal asystole is frequently underrecognized despite being a potentially lethal condition. We report two cases of ictal asystole with right hemispheric onset. These cases are unique since previous literature reports that seizures associated with bradyarrhythmias typically arise from left hemispheric foci. These cases further underscore the importance of clinical vigilance and the need of an enhanced diagnostic biomarker.

Hemispheric lateralization of linguistic prosody recognition in comparison to speech and speaker recognition.

Science.gov (United States)

Kreitewolf, Jens; Friederici, Angela D; von Kriegstein, Katharina

2014-11-15

Hemispheric specialization for linguistic prosody is a controversial issue. While it is commonly assumed that linguistic prosody and emotional prosody are preferentially processed in the right hemisphere, neuropsychological work directly comparing processes of linguistic prosody and emotional prosody suggests a predominant role of the left hemisphere for linguistic prosody processing. Here, we used two functional magnetic resonance imaging (fMRI) experiments to clarify the role of left and right hemispheres in the neural processing of linguistic prosody. In the first experiment, we sought to confirm previous findings showing that linguistic prosody processing compared to other speech-related processes predominantly involves the right hemisphere. Unlike previous studies, we controlled for stimulus influences by employing a prosody and speech task using the same speech material. The second experiment was designed to investigate whether a left-hemispheric involvement in linguistic prosody processing is specific to contrasts between linguistic prosody and emotional prosody or whether it also occurs when linguistic prosody is contrasted against other non-linguistic processes (i.e., speaker recognition). Prosody and speaker tasks were performed on the same stimulus material. In both experiments, linguistic prosody processing was associated with activity in temporal, frontal, parietal and cerebellar regions. Activation in temporo-frontal regions showed differential lateralization depending on whether the control task required recognition of speech or speaker: recognition of linguistic prosody predominantly involved right temporo-frontal areas when it was contrasted against speech recognition; when contrasted against speaker recognition, recognition of linguistic prosody predominantly involved left temporo-frontal areas. The results show that linguistic prosody processing involves functions of both hemispheres and suggest that recognition of linguistic prosody is based on

ERP evidence for hemispheric asymmetries in exemplar-specific explicit memory access.

Science.gov (United States)

Küper, Kristina; Zimmer, Hubert D

2015-11-02

The right cerebral hemisphere (RH) appears to be more effective in representing visual objects as distinct exemplars than the left hemisphere (LH) which is presumably biased towards coding objects at the level of abstract prototypes. As of yet, relatively little is known about the role that asymmetries in exemplar-specificity play at the level of explicit memory retrieval. In the present study, we addressed this issue by examining hemispheric asymmetries in the putative event-related potential (ERP) correlates of familiarity (FN400) and recollection (LPC). In an incidental study phase, pictures of familiar objects were presented centrally. At test, participants performed a memory inclusion task on identical repetitions and different exemplars of study items as well as new items which were presented in only one visual hemifield using the divided visual field technique. With respect to familiarity, we observed exemplar-specific FN400 old/new effects that were more pronounced for identical repetitions than different exemplars, irrespective of the hemisphere governing initial stimulus processing. In contrast, LPC old/new effects were subject to some hemispheric asymmetries indicating that exemplar-specific recollection was more extensive in the RH than in the LH. This further corroborates the idea that hemispheric asymmetries should not be generalized but need to be distinguished not only in different domains but also at different levels of processing.

Effects of memory load on hemispheric asymmetries of colour memory.

Clapp, Wes; Kirk, Ian J; Hausmann, Markus

2007-03-01

Hemispheric asymmetries in colour perception have been a matter of debate for some time. Recent evidence suggests that lateralisation of colour processing may be largely task specific. Here we investigated hemispheric asymmetries during different types and phases of a delayed colour-matching (recognition) memory task. A total of 11 male and 12 female right-handed participants performed colour-memory tasks. The task involved presentation of a set of colour stimuli (encoding), and subsequent indication (forced choice) of which colours in a larger set had previously appeared at the retrieval or recognition phase. The effect of memory load (set size), and the effect of lateralisation at the encoding or retrieval phases were investigated. Overall, the results indicate a right hemisphere advantage in colour processing, which was particularly pronounced in high memory load conditions, and was seen in males rather than female participants. The results suggest that verbal (mnemonic) strategies can significantly affect the magnitude of hemispheric asymmetries in a non-verbal task.

Presentation of words to separate hemispheres prevents interword illusory conjunctions.

Science.gov (United States)

Liederman, J; Sohn, Y S

1999-03-01

We tested the hypothesis that division of inputs between the hemispheres could prevent interword letter migrations in the form of illusory conjunctions. The task was to decide whether a centrally-presented consonant-vowel-consonant (CVC) target word matched one of four CVC words presented to a single hemisphere or divided between the hemispheres in a subsequent test display. During half of the target-absent trials, known as conjunction trials, letters from two separate words (e.g., "tag" and "cop") in the test display could be mistaken for a target word (e.g., "top"). For the other half of the target-absent trails, the test display did not match any target consonants (Experiment 1, N = 16) or it matched one target consonant (Experiment 2, N = 29), the latter constituting true "feature" trials. Bi- as compared to unihemispheric presentation significantly reduced the number of conjunction, but not feature, errors. Illusory conjunctions did not occur when the words were presented to separate hemispheres.

Poole JL, Sadek J, Haaland KY. Ipsilateral deficits in 1-handed shoe tying after left or right hemisphere stroke. To examine 1-handed shoe tying performance and whether cognitive deficits more associated with left or right hemisphere damage differentially affect it after unilateral stroke. Observational cohort comparing ipsilesional shoe tying, spatial and language skills, and limb praxis. Primary care Veterans Affairs and private medical center. Not applicable. Volunteer right-handed sample of adults with left or right hemisphere damage and healthy demographically matched adults. The number of correct trials and the total time to complete 10 trials tying a shoe using the 1-handed method. Both stroke groups had fewer correct trials and were significantly slower tying the shoe than the control group. Spatial skills predicted accuracy and speed after right hemisphere damage. After left hemisphere damage, accuracy was predicted by spatial skills and limb praxis, while speed was predicted by limb praxis only. Ipsilesional shoe tying is similarly impaired after left or right hemisphere damage, but for different reasons. Spatial deficits had a greater influence after right hemisphere damage, and limb apraxia had a greater influence after left hemisphere damage. Language deficits did not affect performance, indicating that aphasia does not preclude using this therapy approach. These results suggest that rehabilitation professionals should consider assessment of limb apraxia and ipsilesional skill training in the performance of everyday tasks.

This discussion will recount some historical observations about establishing partnerships with the customer. It suggests that such partnerships are established as the natural evolutionary product of a continuous improvement culture. Those are warm, ethereal terms about a topic that some people think already suffers from an excess of hot air. We will focus on some real-world activities and workplace artifacts to show there are substantive concepts behind the TQM buzzwords.

2012-01-01

Mental planning and carrying out a plan provoke specific cerebral hemodynamic responses. Gender aspects of hemispheric laterality using rapid cerebral hemodynamics have not been reported. Here, we applied functional transcranial Doppler sonography to examine lateralization of cerebral hemodynamics of the middle cerebral arteries of 28 subjects (14 women and 14 men) performing a standard planning task. There were easy and difficult problems, and mental planning without motor activity was separated from movement execution. Difficult mental planning elicited lateralization to the right hemisphere after 2 or more seconds, a feature that was not observed during movement execution. In females, there was a dominance to the left hemisphere during movement execution. Optimized problem solving yielded an increased laterality change to the right during mental planning. Gender-related hemispheric dominance appears to be condition-dependent, and change of laterality to the right may play a role in optimized performance. Results are of relevance when considering laterality from a perspective of performance enhancement of higher cognitive functions, and also of psychiatric disorders with cognitive dysfunctions and abnormal lateralization patterns such as schizophrenia.

Age-related shifts in hemispheric dominance for syntactic processing.

Science.gov (United States)

Leckey, Michelle; Federmeier, Kara D

2017-12-01

Recent ERP data from young adults have revealed that simple syntactic anomalies elicit different patterns of lateralization in right-handed participants depending upon their familial sinistrality profile (whether or not they have left-handed biological relatives). Right-handed participants who do not have left-handed relatives showed a strongly lateralized response pattern, with P600 responses following left-hemisphere-biased presentations and N400 responses following right-hemisphere-biased presentations. Given that the literature on aging has documented a tendency to change across adulthood from asymmetry of function to a more bilateral pattern, we tested the stability of this asymmetric response to syntactic violations by recording ERPs as 24 older adults (age 60+) with no history of familial sinistrality made grammaticality judgments on simple two-word phrases. Results showed that the asymmetric pattern observed in right-handed adults without familial sinistrality indeed changes with age, such that P600 responses come to be elicited not only with left-hemisphere-biased but also with right-hemisphere-biased presentations in older adults. These findings suggest that, as with many other cognitive functions, syntactic processing becomes more bilateral with age. © 2017 Society for Psychophysiological Research.

Hushie, Martin

2016-09-13

The last few decades have seen a dramatic increase in public-non-governmental organisation (NGO) partnerships in the health sector of many low- and middle- income countries (LMICs) as a means of improving the public's health. However, little research has focused to date on the nature, facilitators and barriers of these partnerships. In-depth qualitative interviews were conducted with 17 participants from five different NGOs and their collaboration with state partners in the Ghanaian health sector at the national and local levels in four regions of the country (Northern, Upper East, Greater Accra, and Eastern) to explore the drivers and nature of these partnerships and their advantages and disadvantages in the effort to improve the public's health. Major findings reveal that: 1) each collaboration between civil society organisations (CSOs) and the state in the health sector demands different partnerships; 2) partnership types can range from equal, formal contractual, decentralized to advocacy ones; 3) commitment by the state and NGOs to work in collaboration lead to improved service delivery, reduced health inequities and disparities; 4) added value of NGOs lies in their knowledge, expertise, community legitimacy, ability to attract donor funding and implementation capacity to address health needs in geographical areas or communities where the government does not reach and for services, which it does not provide and 5) success factors and challenges to be considered, moving forward to promote such partnerships in other LMICs. Recommendations are offered for NGOs, governments, donors, and future research including studying the organisational effectiveness and sustainability of these partnerships to deliver effective and efficient health outcomes to recommend universal best practices in health care.

Many examples of partnerships between academic and service settings were thoroughly described and best practices suggested, most often, however, without formal evaluation of outcomes. Nursing leaders in both settings have a long tradition of partnering with very little replicable evidence to support their efforts. It is critical that future initiatives evaluate the effectiveness of these partnerships, not only to ensure quality of patient outcomes but also to maximize efforts at building capacity for tomorrow's workforce.

Functional magnetic resonance imaging to determine hemispheric language dominance prior to carotid endarterectomy.

Science.gov (United States)

Smits, M; Wieberdink, R G; Bakker, S L M; Dippel, D W J

2011-04-01

We describe a left-handed patient with transient aphasia and bilateral carotid stenosis. Computed tomography (CT) arteriography showed a 90% stenosis of the right and 30% stenosis of the left internal carotid artery. Head CT and magnetic resonance imaging (MRI) of the brain showed no recent ischemic changes. As only the symptomatic side would require surgical intervention, and because hemispheric dominance for language in left-handed patients may be either left or right sided, a preoperative assessment of hemispheric dominance was required. We used functional MRI to determine hemispheric dominance for language and hence to establish the indication for carotid endarterectomy surgery. Functional MRI demonstrated right hemispheric dominance for language and right-sided carotid endarterectomy was performed. We propose that the clinical use of functional MRI as a noninvasive imaging technique for the assessment of hemispheric language dominance may be extended to the assessment of hemispheric language dominance prior to carotid endarterectomy.

Hemispheric metacontrol and cerebral dominance in healthy individuals investigated by means of chimeric faces.

Science.gov (United States)

Urgesi, Cosimo; Bricolo, Emanuela; Aglioti, Salvatore M

2005-08-01

Cerebral dominance and hemispheric metacontrol were investigated by testing the ability of healthy participants to match chimeric, entire, or half faces presented tachistoscopically. The two hemi-faces compounding chimeric or entire stimuli were presented simultaneously or asynchronously at different exposure times. Participants did not consciously detect chimeric faces for simultaneous presentations lasting up to 40 ms. Interestingly, a 20 ms separation between each half-chimera was sufficient to induce detection of conflicts at a conscious level. Although the presence of chimeric faces was not consciously perceived, performance on chimeric faces was poorer than on entire- and half-faces stimuli, thus indicating an implicit processing of perceptual conflicts. Moreover, the precedence of hemispheric stimulation over-ruled the right hemisphere dominance for face processing, insofar as the hemisphere stimulated last appeared to influence the response. This dynamic reversal of cerebral dominance, however, was not caused by a shift in hemispheric specialization, since the level of performance always reflected the right hemisphere specialization for face recognition. Thus, the dissociation between hemispheric dominance and specialization found in the present study hints at the existence of hemispheric metacontrol in healthy individuals.

Water. Unresolved emergency of the Southern hemisphere

International Nuclear Information System (INIS)

Lotti, C.

2001-01-01

Among the serious dramas in the Southern hemisphere, the most serious relates to health, and the most serious health problem is dysentery among the rural population, caused by the lack of unpolluted water. Bad management frustrates much of the aid sent to this part of the world, including projects to help the water crisis. In view of the success, it would appear that a concrete solution could be found within a decade, at a cost that can easily be sustained by the rich world, so long as funds are managed honestly. Much more ambitious and, at least for the moment, beyond all concrete possibility, is the project to provide a barrel of water per head to each person in the southern hemisphere. Providing unpolluted water and facilitating farming development through minor irrigation and family cattle-raising schemes is an idea that appears entirely Utopian. The conclusion provides a critical analysis of the major hydraulic works essential for true development, but effective only if the human environment is ready to receive them, whereas minor works are useful in any case - at village level - to resolve the thirst of the southern hemisphere [it

Hemispheric asymmetry of liking for representational and abstract paintings.

Science.gov (United States)

Nadal, Marcos; Schiavi, Susanna; Cattaneo, Zaira

2017-10-13

Although the neural correlates of the appreciation of aesthetic qualities have been the target of much research in the past decade, few experiments have explored the hemispheric asymmetries in underlying processes. In this study, we used a divided visual field paradigm to test for hemispheric asymmetries in men and women's preference for abstract and representational artworks. Both male and female participants liked representational paintings more when presented in the right visual field, whereas preference for abstract paintings was unaffected by presentation hemifield. We hypothesize that this result reflects a facilitation of the sort of visual processes relevant to laypeople's liking for art-specifically, local processing of highly informative object features-when artworks are presented in the right visual field, given the left hemisphere's advantage in processing such features.

Proportional feedback control of laminar flow over a hemisphere

2016-08-15

In the present study, we perform a proportional feedback control of laminar flow over a hemisphere at Re = 300 to reduce its lift fluctuations by attenuating the strength of the vortex shedding. As a control input, blowing/suction is distributed on the surface of hemisphere before the separation, and its strength is linearly proportional to the transverse velocity at a sensing location in the centerline of the wake. The sensing location is determined based on a correlation function between the lift force and the time derivative of sensing velocity. The optimal proportional gains for the proportional control are obtained for the sensing locations considered. The present control successfully attenuates the velocity fluctuations at the sensing location and three dimensional vertical structures in the wake, resulting in the reduction of lift fluctuations of hemisphere.

A Sociomaterial Account of Partnership, Signatures and Accountability in Practice

Directory of Open Access Journals (Sweden)

Nick Hopwood

2014-06-01

Full Text Available Professional work is often heralded as undergoing radical transformation. This paper focuses on partnership between health professionals and families as a specific instance of changes aimed at delivering shared responsibility and joint knowledge work. An ethnographic study of a residential child and family health services provides the empirical basis for a detailed examination of what is signed, by whom, and with what effects. I show how signing and signatures provide fertile starting points for sociomaterial analysis, a rich empirical reference point for what Nicolini calls “zooming in” on particular instances, and “zooming out” to understand their connections to other practices. Schatzki’s practice theory is used as a theoretical basis, drawing also on Kemmis’ notions of practice architectures and ecologies of practices to elaborate such connections. I trace how acts of signing and signatures as artefacts are produced through and reflect partnership, indeed pointing to significant changes in professional work. However I also show that wider ecologies of practices present architectures that challenge diffuse accountability and shared epistemic work.

Community–University Partnerships: Using Participatory Action Learning and Action Research (PALAR

Directory of Open Access Journals (Sweden)

Judith Kearney

2013-09-01

Full Text Available This article positions participatory action learning and action research (PALAR as a preferred methodology for community-university partnerships to achieve a holistic outcome that benefits the common interest. Evidence for this claim is illustrated through case studies of two community engagement programs, one in South Africa and the other in Australia. The South African study explains how relationships, reflection and recognition (the three R’s of PALAR are important elements that promote a truly participatory approach to knowledge creation and practical improvement in social circumstances. The Australian study then highlights what can be achieved. It does this by showing the potential for PALAR participants to learn how to design and implement a community engagement program, and how to cascade their own learning into their community to improve educational opportunities. Both studies demonstrate PALAR’s potential to disrupt traditional understandings of the research process, particularly in terms of researcher–participant relationships. At the same time, both studies identify the challenges arising from the theoretical and practical implications of PALAR as an approach to community development. This article is therefore significant for universities and funding organisations engaging in community-based research and development through partnerships, specifically in contexts of disadvantage. Keywords: Participatory action learning and action research, PALAR, community development, community engagement, community partnerships, disadvantaged communities, higher education.

Vestibulo-cortical Hemispheric Dominance: the link between Anxiety and the Vestibular System?

Science.gov (United States)

Bednarczuk, Nadja F; Casanovas Ortega, Marta; Fluri, Anne-Sophie; Arshad, Qadeer

2018-05-16

Vestibular processing and anxiety networks are functionally intertwined, as demonstrated by reports of reciprocal influences upon each other. Yet whether there is an underlying link between these two systems remains unknown Previous findings have highlighted the involvement of hemispheric lateralisation in processing of both anxiety and vestibular signals. Accordingly, we explored the interaction between vestibular cortical processing and anxiety by assessing the relationship between anxiety levels and the degree of hemispheric lateralisation of vestibulo-cortical processing in 64 right-handed, healthy individuals. Vestibulo-cortical hemispheric lateralisation was determined by gaging the degree of caloric-induced nystagmus suppression following modulation of cortical excitability using trans-cranial direct current stimulation targeted over the posterior parietal cortex, an area implicated in the processing of vestibular signals. The degree of nystagmus suppression yields an objective biomarker, allowing the quantification of the degree of right vestibulo-cortical hemisphere dominance. Anxiety levels were quantified using the Trait component of the Spielberger State-Trait Anxiety Questionnaire. Our findings demonstrate that the degree of an individual's vestibulo-cortical hemispheric dominance correlates with their anxiety levels. That is, those individuals with greater right hemispheric vestibulo-cortical dominance exhibited lower levels of anxiety. By extension, our results support the notion that hemispheric lateralisation determines an individual's emotional processing, thereby linking cortical circuits involved in processing anxiety and vestibular signals respectively.

Genskow, Kenneth D.

2009-03-01

Experience with collaborative approaches to natural resource and environmental management has grown substantially over the past 20 years, and multi-interest, shared-resources initiatives have become prevalent in the United States and internationally. Although often viewed as “grass-roots” and locally initiated, governmental participants are crucial to the success of collaborative efforts, and important questions remain regarding their appropriate roles, including roles in partnership initiation. In the midst of growing governmental support for collaborative approaches in the mid-1990s, the primary natural resource and environmental management agency in Wisconsin (USA) attempted to generate a statewide system of self-sustaining, collaborative partnerships, organized around the state’s river basin boundaries. The agency expected the partnerships to enhance participation by stakeholders, leverage additional resources, and help move the agency toward more integrated and ecosystem-based resource management initiatives. Most of the basin partnerships did form and function, but ten years after this initiative, the agency has moved away from these partnerships and half have disbanded. Those that remain active have changed, but continue to work closely with agency staff. Those no longer functioning lacked clear focus, were dependent upon agency leadership, or could not overcome issues of scale. This article outlines the context for state support of collaborative initiatives and explores Wisconsin’s experience with basin partnerships by discussing their formation and reviewing governmental roles in partnerships’ emergence and change. Wisconsin’s experience suggests benefits from agency support and agency responsiveness to partnership opportunities, but cautions about expectations for initiating general-purpose partnerships.

Revitalizing a Dying School-Business Partnership

The notion of business involvement in helping to improve public schools is not new. Although business involvement faded somewhat in the 1960s and 1970s, a resurgence in business involvement began in the late seventies and early eighties. School-business partnerships have been steadily on the rise from around 40,000 in 1983 to over 200,000 by the mid-1990's. When schools and businesses become involved in partnerships certain conditions must be present for the partnerships to succeed. Th...

Big Sky Carbon Sequestration Partnership

2005-11-01

The Big Sky Carbon Sequestration Partnership, led by Montana State University, is comprised of research institutions, public entities and private sectors organizations, and the Confederated Salish and Kootenai Tribes and the Nez Perce Tribe. Efforts under this Partnership in Phase I fall into four areas: evaluation of sources and carbon sequestration sinks that will be used to determine the location of pilot demonstrations in Phase II; development of GIS-based reporting framework that links with national networks; designing an integrated suite of monitoring, measuring, and verification technologies and assessment frameworks; and initiating a comprehensive education and outreach program. The groundwork is in place to provide an assessment of storage capabilities for CO2 utilizing the resources found in the Partnership region (both geological and terrestrial sinks), that would complement the ongoing DOE research agenda in Carbon Sequestration. The region has a diverse array of geological formations that could provide storage options for carbon in one or more of its three states. Likewise, initial estimates of terrestrial sinks indicate a vast potential for increasing and maintaining soil C on forested, agricultural, and reclaimed lands. Both options include the potential for offsetting economic benefits to industry and society. Steps have been taken to assure that the GIS-based framework is consistent among types of sinks within the Big Sky Partnership area and with the efforts of other DOE regional partnerships. The Partnership recognizes the critical importance of measurement, monitoring, and verification technologies to support not only carbon trading but all policies and programs that DOE and other agencies may want to pursue in support of GHG mitigation. The efforts in developing and implementing MMV technologies for geological sequestration reflect this concern. Research is also underway to identify and validate best management practices for soil C in the

This initiative provides fleets with specialized resources, expertise, and support to successfully incorporate alternative fuels and fuel-saving measures into their operations. The National Clean Fleets Partnership builds on the established success of DOE's Clean Cities program, which reduces petroleum consumption at the community level through a nationwide network of coalitions that work with local stakeholders. Developed with input from fleet managers, industry representatives, and Clean Cities coordinators, the National Clean Fleets Partnership goes one step further by working with large private-sector fleets.

The effect of cognitive load on hemispheric asymmetries in true and false memory.

Science.gov (United States)

Tat, Michael J; Azuma, Tamiko

2016-01-01

Studies examining hemispheric asymmetries in false memory have shown that the right hemisphere (RH) is more susceptible to false memories compared to the left hemisphere (LH). Theories suggest that hemispheric asymmetries in true and false memory may be due to differences in representational coding and the use of top-down mechanisms in each hemisphere. In the current study, the Deese-Roediger-McDermott false memory paradigm was used in conjunction with divided visual field presentation to examine the role of top-down mechanisms in hemispheric asymmetries of true and false memory. In Experiment 1, participants studied lists of related words while completing secondary cognitive load tasks. In Experiment 2, the secondary tasks were administered during memory retrieval instead of memory encoding. Results revealed that cognitive loads imposed during the study phase influenced veridical memory in the LH more than the RH, but cognitive loads imposed during retrieval did not influence veridical memory in either hemisphere. Surprisingly, false memory rates were not influenced by cognitive loads and were higher in the LH. These data provide evidence that, at least for veridical memory, top-down control mechanisms are used more readily for the encoding of information into memory in the LH compared to the RH.

Elasto-plastic impact of hemispherical shell impacting on hard rigid sphere

Raftopoulos, D. D.; Spicer, A. L.

1976-01-01

An analysis of plastic stress waves for cylindrical metallic projectile in impact is extended to an analysis of a hemispherical shell suffereing plastic deformation during the process of impact. It is assumed that the hemispherical shell with a prescribed launch velocity impinges a fixed rigid sphere of diameter equal to the internal diameter of the shell. The dynamic biaxial state of stress present in the shell during deformation is investigated. The analysis is valuable for studying the state of stress during large plastic deformation of a hemispherical shell.

Right-hemisphere lesions (RHL) may impair inference comprehension. However, comparative studies between left-hemisphere lesions (LHL) and RHL are rare, especially regarding reading comprehension. Moreover, further knowledge of the influence of cognition on inferential processing in this task is needed. To compare the performance of patients with RHL and LHL on an inference reading comprehension task. We also aimed to analyze the effects of lesion site and to verify correlations between cognitive functions and performance on the task. Seventy-five subjects were equally divided into the groups RHL, LHL, and control group (CG). The Implicit Management Test was used to evaluate inference comprehension. In this test, subjects read short written passages and subsequently answer five types of questions (explicit, logical, distractor, pragmatic, and other), which require different types of inferential reasoning. The cognitive functional domains of attention, memory, executive functions, language, and visuospatial abilities were assessed using the Cognitive Linguistic Quick Test (CLQT). The LHL and RHL groups presented difficulties in inferential comprehension in comparison with the CG. However, the RHL group presented lower scores than the LHL group on logical, pragmatic and other questions. A covariance analysis did not show any effect of lesion site within the hemispheres. Overall, all cognitive domains were correlated with all the types of questions from the inference test (especially logical, pragmatic, and other). Attention and visuospatial abilities affected the scores of both the RHL and LHL groups, and only memory influenced the performance of the RHL group. Lesions in either hemisphere may cause difficulties in making inferences during reading. However, processing more complex inferences was more difficult for patients with RHL than for those with LHL, which suggests that the right hemisphere plays an important role in tasks with higher comprehension demands

Moral judgement by the disconnected left and right cerebral hemispheres: a split-brain investigation.

Science.gov (United States)

Steckler, Conor M; Hamlin, J Kiley; Miller, Michael B; King, Danielle; Kingstone, Alan

2017-07-01

Owing to the hemispheric isolation resulting from a severed corpus callosum, research on split-brain patients can help elucidate the brain regions necessary and sufficient for moral judgement. Notably, typically developing adults heavily weight the intentions underlying others' moral actions, placing greater importance on valenced intentions versus outcomes when assigning praise and blame. Prioritization of intent in moral judgements may depend on neural activity in the right hemisphere's temporoparietal junction, an area implicated in reasoning about mental states. To date, split-brain research has found that the right hemisphere is necessary for intent-based moral judgement. When testing the left hemisphere using linguistically based moral vignettes, split-brain patients evaluate actions based on outcomes, not intentions. Because the right hemisphere has limited language ability relative to the left, and morality paradigms to date have involved significant linguistic demands, it is currently unknown whether the right hemisphere alone generates intent-based judgements. Here we use nonlinguistic morality plays with split-brain patient J.W. to examine the moral judgements of the disconnected right hemisphere, demonstrating a clear focus on intent. This finding indicates that the right hemisphere is not only necessary but also sufficient for intent-based moral judgement, advancing research into the neural systems supporting the moral sense.

Hemispheric differences in electrical and hemodynamic responses during hemifield visual stimulation with graded contrasts.

Science.gov (United States)

Si, Juanning; Zhang, Xin; Zhang, Yujin; Jiang, Tianzi

2017-04-01

A multimodal neuroimaging technique based on electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) was used with horizontal hemifield visual stimuli with graded contrasts to investigate the retinotopic mapping more fully as well as to explore hemispheric differences in neuronal activity, the hemodynamic response, and the neurovascular coupling relationship in the visual cortex. The fNIRS results showed the expected activation over the contralateral hemisphere for both the left and right hemifield visual stimulations. However, the EEG results presented a paradoxical lateralization, with the maximal response located over the ipsilateral hemisphere but with the polarity inversed components located over the contralateral hemisphere. Our results suggest that the polarity inversion as well as the latency advantage over the contralateral hemisphere cause the amplitude of the VEP over the contralateral hemisphere to be smaller than that over the ipsilateral hemisphere. Both the neuronal and hemodynamic responses changed logarithmically with the level of contrast in the hemifield visual stimulations. Moreover, the amplitudes and latencies of the visual evoked potentials (VEPs) were linearly correlated with the hemodynamic responses despite differences in the slopes.

Homotopic organization of essential language sites in right and bilateral cerebral hemispheric dominance.

Science.gov (United States)

Chang, Edward F; Wang, Doris D; Perry, David W; Barbaro, Nicholas M; Berger, Mitchel S

2011-04-01

Language dominance in the right hemisphere is rare. Therefore, the organization of essential language sites in the dominant right hemisphere is unclear, especially compared with cases involving the more prevalent left dominant hemisphere. The authors reviewed the medical records of 15 patients who underwent awake craniotomy for tumor or epilepsy surgery and speech mapping of right hemisphere perisylvian language areas at the University of California, San Francisco. All patients were determined to have either complete right-sided or bilateral language dominance by preoperative Wada testing. All patients but one were left-handed. Of more than 331 total stimulation sites, 27 total sites were identified as essential for language function (14 sites for speech arrest/anarthria; 12 for anomia; and 1 for alexia). While significant interindividual variability was observed, the general pattern of language organization was similar to classic descriptions of frontal language production and posterior temporal language integration for the left hemisphere. Speech arrest sites were clustered in the ventral precentral gyrus and pars opercularis. Anomia sites were more widely distributed, but were focused in the posterior superior and middle temporal gyri as well as the inferior parietal gyrus. One alexia site was found over the superior temporal gyrus. Face sensory and motor cortical sites were also identified along the ventral sensorimotor strip. The prevalence and specificity of essential language sites were greater in unilateral right hemisphere-dominant patients, compared with those with bilateral dominance by Wada testing. The authors' results suggest that the organization of language in right hemisphere dominance mirrors that of left hemisphere dominance. Awake speech mapping is a safe and reliable surgical adjunct in these rare clinical cases and should be done in the setting of right hemisphere dominance to avoid preventable postoperative aphasia.

Inclusion of American Indian and Alaska Native (AI/AN) populations in pharmacogenetic research is key if the benefits of pharmacogenetic testing are to reach these communities. Community-based participatory research (CBPR) offers a model to engage these communities in pharmacogenetics. An academic-community partnership between the University of Montana (UM) and the Confederated Salish and Kootenai Tribes (CSKT) was established to engage the community as partners and advisors in pharmacogenetic research. A community advisory committee, the Community Pharmacogenetics Advisory Council (CPAC), was established to ensure community involvement in the research process. To promote bidirectional learning, researchers gave workshops and presentations about pharmacogenetic research to increase research capacity and CPAC members trained researchers in cultural competencies. As part of our commitment to a sustainable relationship, we conducted a self-assessment of the partnership, which included surveys and interviews with CPAC members and researchers. Academic and community participants agree that the partnership has promoted a bidirectional exchange of knowledge. Interviews showed positive feedback from the perspectives of both the CPAC and researchers. CPAC members discussed their trust in and support of the partnership, as well as having learned more about research processes and pharmacogenetics. Researchers discussed their appreciation of CPAC involvement in the project and guidance the group provided in understanding the CSKT community and culture. We have created an academic-community partnership to ensure CSKT community input and to share decision making about pharmacogenetic research. Our CBPR approach may be a model for engaging AI/AN people, and other underserved populations, in genetic research.

Experimental Study on Critical Power in a Hemispherical Narrow Gap

International Nuclear Information System (INIS)

Park, Rae-Joon; Ha, Kwang-Soon; Kim, Sang-Baik; Kim, Hee-Dong; Jeong, Ji-Hwan

2002-01-01

An experimental study of critical heat flux in gap (CHFG) has been performed to investigate the inherent cooling mechanism in a hemispherical narrow gap. The objectives of the CHFG test are to measure critical power from a critical heat removal rate through the hemispherical narrow gap using distilled water with experimental parameters of system pressure and gap width. The CHFG test results have shown that a countercurrent flow limitation (CCFL) brings about local dryout at the small edge region of the upper part and finally global dryout in a hemispherical narrow gap. Increases in the gap width and pressure lead to an increase in critical power. The measured values of critical power are lower than the predictions made by other empirical CHF correlations applicable to flat plate, annuli, and small spherical gaps. The measured data on critical power in the hemispherical narrow gaps have been correlated using nondimensional parameters with a range of approximately ±20%. The developed correlation has been expanded to apply the spherical geometry using the Siemens/KWU correlation

The GLOBE Program is a worldwide science and education partnership endeavor designed to increase scientific understanding of Earth as a system, support improved student achievement in science and math, and enhance environmental awareness through inquiry-based learning activities. GLOBE began on the premise that teachers and their students would partner with scientists to collect and analyze environmental data using specific protocols in five study areas - atmosphere, soils, hydrology, land cover, and phenology. As the GLOBE network grew, additional partnerships flourished making GLOBE an unprecedented collaboration of individuals worldwide - primary, secondary, and tertiary students, teachers and teacher educators, scientists, government officials, and others - to improve K-12 education. Since its inception in 1994, more than one million students in over 14,000 schools around the world have taken part in The GLOBE Program. The GLOBE Web site (http://www.globe.gov) is the repository for over 11 million student-collected data measurements easily accessible to students and scientists worldwide. Utilizing the advantages of the Internet for information sharing and communication, GLOBE has created an international community. GLOBE enriches students by giving them the knowledge and skills that they will need to become informed citizens and responsible decision-makers in an increasingly complex world. Understanding that all members of a community must support change if it is to be sustainable, GLOBE actively encourages the development of GLOBE Learning Communities (GLCs) which are designed to get diverse stakeholder groups involved in a local or regional environmental issue. Central to the GLC is the engagement of local schools. GLCs go beyond individual teachers implementing GLOBE in the isolation of their classrooms. Instead, the GLC brings multiple teachers and grade levels together to examine environmental issues encouraging the participation of a broad range of

Hypothalamic digoxin, hemispheric dominance, and neurobiology of love and affection.

Science.gov (United States)

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-05-01

The human hypothalamus produces an endogenous membrane Na+-K+ ATPase inhibitor, digoxin, which can regulate neuronal transmission. The digoxin status and neurotransmitter patterns were studied in individuals with a predilection to fall in love. It was also studied in individuals with differing hemispheric dominance to find out the role of cerebral dominance in this respect. In individuals with a predilection to fall in love there was decreased digoxin synthesis, increased membrane Na+-K+ ATPase activity, decreased tryptophan catabolites (serotonin, quinolinic acid, and nicotine), and increased tyrosine catabolites (dopamine, noradrenaline, and morphine). This pattern correlated with that obtained in left hemispheric chemical dominance. Hemispheric dominance and hypothalamic digoxin could regulate the predisposition to fall in love.

Hemispherical reflectance model for passive images in an outdoor environment.

Kim, Charles C; Thai, Bea; Yamaoka, Neil; Aboutalib, Omar

2015-05-01

We present a hemispherical reflectance model for simulating passive images in an outdoor environment where illumination is provided by natural sources such as the sun and the clouds. While the bidirectional reflectance distribution function (BRDF) accurately produces radiance from any objects after the illumination, using the BRDF in calculating radiance requires double integration. Replacing the BRDF by hemispherical reflectance under the natural sources transforms the double integration into a multiplication. This reduces both storage space and computation time. We present the formalism for the radiance of the scene using hemispherical reflectance instead of BRDF. This enables us to generate passive images in an outdoor environment taking advantage of the computational and storage efficiencies. We show some examples for illustration.

Handedness results from Complementary Hemispheric Dominance, not Global Hemispheric Dominance: Evidence from Mechanically Coupled Bilateral Movements.

Two contrasting views of handedness can be described as 1) complementary dominance, in which each hemisphere is specialized for different aspects of motor control, and 2) global dominance, in which the hemisphere contralateral to the dominant arm is specialized for all aspects of motor control. The present study sought to determine which motor lateralization hypothesis best predicts motor performance during common bilateral task of stabilizing an object (e.g. bread) with one hand while applying forces to the object (e.g. slicing) using the other hand. We designed an experimental equivalent of this task, performed in a virtual environment with the unseen arms supported by frictionless air-sleds. The hands were connected by a spring, and the task was to maintain the position of one hand, while moving the other hand to a target. Thus, the reaching hand was required to take account of the spring load to make smooth and accurate trajectories, while the stabilizer hand was required to impede the spring load to keep a constant position. Right-handed subjects performed two task sessions (right hand reach and left hand stabilize; left hand reach and right hand stabilize) with the order of the sessions counterbalanced between groups. Our results indicate a hand by task-component interaction, such that the right hand showed straighter reaching performance while the left showed more stable holding performance. These findings provide support for the complementary dominance hypothesis and suggest that the specializations of each cerebral hemisphere for impedance and dynamic control mechanisms are expressed during bilateral interactive tasks.

Agricultural regions in the United States are experimenting with sustainability partnerships that, among other goals, seek to improve growers' ability to manage their vineyards sustainably. In this paper, we analyze the association between winegrape grower participation in sustainability partnership activities and practice adoption in three winegrowing regions of California. Using data gathered from a survey of 822 winegrape growers, we find a positive association between participation and adoption of sustainable practices, which holds most strongly for practices in which the perceived private benefits outweigh the costs, and for growers with relatively dense social networks. We highlight the mechanisms by which partnerships may catalyze sustainable farm management, and discuss the implications of these findings for improving sustainability partnerships. Taken together, we provide one of the most comprehensive quantitative analyses to date regarding the effectiveness of agricultural sustainability partnerships for improving farm management.

European and Developing Countries Clinical Trials Partnership (EDCTP) was founded in 2003 by the European Parliament and Council. It is a partnership of 14 European Union (EU) member states, Norway, Switzerland, and Developing Countries, formed to fund acceleration of new clinical trial interventions to fight the human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS), malaria and tuberculosis (TB) in the sub-Saharan African region. EDCTP seeks to be synergistic with other funding bodies supporting research on these diseases. EDCTP promotes collaborative research supported by multiple funding agencies and harnesses networking expertise across different African and European countries. EDCTP is different from other similar initiatives. The organisation of EDCTP blends important aspects of partnership that includes ownership, sustainability and responds to demand-driven research. The Developing Countries Coordinating Committee (DCCC); a team of independent scientists and representatives of regional health bodies from sub-Saharan Africa provides advice to the partnership. Thus EDCTP reflects a true partnership and the active involvement and contribution of these African scientists ensures joint ownership of the EDCTP programme with European counterparts. The following have been the major achievements of the EDCTP initiative since its formation in 2003; i) increase in the number of participating African countries from two to 26 in 2008 ii) the cumulative amount of funds spent on EDCTP projects has reached 150 m euros, iii) the cumulative number of clinical trials approved has reached 40 and iv) there has been a significant increase number and diversity in capacity building activities. While we recognise that EDCTP faced enormous challenges in its first few years of existence, the strong involvement of African scientists and its new initiatives such as unconditional funding to regional networks of excellence in sub-Saharan Africa is envisaged to

Full Text Available The article examines tendencies of the development of new organizational forms of partnership and marks several problems of their usage in Russian conditions by the example of the Novosibirsk region. Modern forms of networking and partnership of commercial companies and universities, research institutes and other organizations, such as clusters, strategic alliances, technology platforms, business ecosystems and other, are focused on the development of new market opportunities and gaining competitive advantage through the sharing of assets and expertise. Two groups of strategic partnership initiatives in the business were emphasized: some initiatives are shown by the state, while some come from the companies. It has been shown that the development of digital technologies, which allows to establish connection between geographically separated participants, promotes the formation of new partnership tools, such as the technology platforms and business ecosystems built on their basis.

Pledges of Commitment and Cooperation in Partnerships

Directory of Open Access Journals (Sweden)

Full Text Available We use experimental methods to investigate whether pledges of commitment can improve cooperation in endogenously-formed partnerships facing a social dilemma. Treatments vary in terms of the individual’s: (1 opportunity to commit to their partner; (2 the cost of dissolving committed partnerships; and (3 the distribution of these dissolution costs between partners. Our findings show that pledges of commitment alone can increase cooperation and welfare in committed partnerships. The introduction of relatively large and equally split costs yields similar gains. In contrast, when costs to dissolve committed partnerships fall solely on the individual choosing to break up, pledges of commitment fail to improve cooperation and welfare.

Crossed Aphasia in a Patient with Anaplastic Astrocytoma of the Non-Dominant Hemisphere.

Science.gov (United States)

Prater, Stephanie; Anand, Neil; Wei, Lawrence; Horner, Neil

2017-09-01

Aphasia describes a spectrum of speech impairments due to damage in the language centers of the brain. Insult to the inferior frontal gyrus of the dominant cerebral hemisphere results in Broca's aphasia - the inability to produce fluent speech. The left cerebral hemisphere has historically been considered the dominant side, a characteristic long presumed to be related to a person's "handedness". However, recent studies utilizing fMRI have shown that right hemispheric dominance occurs more frequently than previously proposed and despite a person's handedness. Here we present a case of a right-handed patient with Broca's aphasia caused by a right-sided brain tumor. This is significant not only because the occurrence of aphasia in right-handed-individuals with right hemispheric brain damage (so-called "crossed aphasia") is unusual but also because such findings support dissociation between hemispheric linguistic dominance and handedness.

The right hemisphere supports but does not replace left hemisphere auditory function in patients with persisting aphasia.

In this study, we used magnetoencephalography and a mismatch paradigm to investigate speech processing in stroke patients with auditory comprehension deficits and age-matched control subjects. We probed connectivity within and between the two temporal lobes in response to phonemic (different word) and acoustic (same word) oddballs using dynamic causal modelling. We found stronger modulation of self-connections as a function of phonemic differences for control subjects versus aphasics in left primary auditory cortex and bilateral superior temporal gyrus. The patients showed stronger modulation of connections from right primary auditory cortex to right superior temporal gyrus (feed-forward) and from left primary auditory cortex to right primary auditory cortex (interhemispheric). This differential connectivity can be explained on the basis of a predictive coding theory which suggests increased prediction error and decreased sensitivity to phonemic boundaries in the aphasics' speech network in both hemispheres. Within the aphasics, we also found behavioural correlates with connection strengths: a negative correlation between phonemic perception and an inter-hemispheric connection (left superior temporal gyrus to right superior temporal gyrus), and positive correlation between semantic performance and a feedback connection (right superior temporal gyrus to right primary auditory cortex). Our results suggest that aphasics with impaired speech comprehension have less veridical speech representations in both temporal lobes, and rely more on the right hemisphere auditory regions, particularly right superior temporal gyrus, for processing speech. Despite this presumed compensatory shift in network connectivity, the patients remain significantly impaired.

West, Florence; Dawson, Angela; Homer, Caroline S E

2017-07-01

Midwifery educators play a critical role in strengthening the midwifery workforce globally, including in low and lower-middle income countries (LMIC) to ensure that midwives are adequately prepared to deliver quality midwifery care. The most effective approach to building midwifery educator capacity is not always clear. The aim of this study was to determine how one capacity building approach in Papua New Guinea (PNG) used international partnerships to improve teaching and learning. A qualitative exploratory case study design was used to explore the perspectives of 26 midwifery educators working in midwifery education institutions in PNG. Seven themes were identified which provide insights into the factors that enable and constrain midwifery educator capacity building. The study provides insights into strategies which may aid institutions and individuals better plan and implement international midwifery partnerships to strengthen context-specific knowledge and skills in teaching. Further research is necessary to assess how these findings can be transferred to other contexts. Copyright © 2017 Elsevier Ltd. All rights reserved.

An Innovative Approach to Addressing Childhood Obesity: A Knowledge-Based Infrastructure for Supporting Multi-Stakeholder Partnership Decision-Making in Quebec, Canada

Directory of Open Access Journals (Sweden)

Nii Antiaye Addy

2015-01-01

Full Text Available Multi-stakeholder partnerships (MSPs have become a widespread means for deploying policies in a whole of society strategy to address the complex problem of childhood obesity. However, decision-making in MSPs is fraught with challenges, as decision-makers are faced with complexity, and have to reconcile disparate conceptualizations of knowledge across multiple sectors with diverse sets of indicators and data. These challenges can be addressed by supporting MSPs with innovative tools for obtaining, organizing and using data to inform decision-making. The purpose of this paper is to describe and analyze the development of a knowledge-based infrastructure to support MSP decision-making processes. The paper emerged from a study to define specifications for a knowledge-based infrastructure to provide decision support for community-level MSPs in the Canadian province of Quebec. As part of the study, a process assessment was conducted to understand the needs of communities as they collect, organize, and analyze data to make decisions about their priorities. The result of this process is a “portrait”, which is an epidemiological profile of health and nutrition in their community. Portraits inform strategic planning and development of interventions, and are used to assess the impact of interventions. Our key findings indicate ambiguities and disagreement among MSP decision-makers regarding causal relationships between actions and outcomes, and the relevant data needed for making decisions. MSP decision-makers expressed a desire for easy-to-use tools that facilitate the collection, organization, synthesis, and analysis of data, to enable decision-making in a timely manner. Findings inform conceptual modeling and ontological analysis to capture the domain knowledge and specify relationships between actions and outcomes. This modeling and analysis provide the foundation for an ontology, encoded using OWL 2 Web Ontology Language. The ontology is developed

EDITORIAL: Northern Hemisphere high latitude climate and environmental change

Science.gov (United States)

Groisman, Pavel; Soja, Amber

2007-10-01

High Northern Hemisphere latitudes are undergoing rapid and significant change associated with climate warming. Climatic change in this region interacts with and affects the rate of the global change through atmospheric circulation, biogeophysical, and biogeochemical feedbacks. Changes in the surface energy balance, hydrologic cycle, and carbon budget feedback to regional and global weather and climate systems. Two-thirds of the Northern Hemisphere high latitude land mass resides in Northern Eurasia (~20% of the global land mass), and this region has undergone sweeping socio-economic change throughout the 20th century. How this carbon-rich, cold region component of the Earth system functions as a regional entity and interacts with and feeds back to the greater global system is to a large extent unknown. To mitigate the deficiencies in understanding these feedbacks, which may in turn hamper our understanding of the global change rates and patterns, an initiative was formed. Three years ago the Northern Eurasia Earth Science Partnership Initiative (NEESPI) was established to address large-scale and long-term manifestations of climate and environmental change in this region. The NEESPI Science Plan and its Executive Summary have been published at the NEESPI web site (neespi.org). Since 2004, NEESPI participants have been able to seed several waves of research proposals to international and national funding agencies and institutions and also contribute to the International Polar Year. Currently, NEESPI is widely recognized and endorsed by several Earth System Science Partnership (ESSP) programmes and projects: the International Geosphere and Biosphere Programme, the World Climate Research Programme through the Global Energy and Water Cycle Experiment and Climate and Cryosphere Projects, the Global Water System Project, Global Carbon Project, Global Land Project, and the Integrated Land Ecosystem—Atmosphere Processes Study.

Full Text Available This article explores the current debate around family-school partnerships. Traditional family-school partnership theories do not account for the intended voices of Cambodian families. This article draws from existing research on Southeast Asian families more generally in order to develop a research-based, data-driven family-school partnership conceptual framework for Cambodian American families. It is believed that a pro-ethnic, voice-centric family-school partnership fosters an inclusive, supportive learning environment for Cambodian children. The logic undergirding that belief assumes that this partnership is likelyto increase cultural awareness between critical home-school partners. At the very least, the proposed concept model serves as a theoretical building block upon which an empirical research study can be built. That study is encouraged to explore the implications of establishing a family-school partnership that reflects the sense and sensibilities of Cambodian families, particularly those stemming from lower income backgrounds. Implicit in the review is the premium placed on challenging Eurocentric, middle-class partnership paradigms to account for the authentic voices of ethnic minorities, and the utility of disaggregating data for Southeast Asians, given the array of cultural and linguistic differences spanningthe Asian American community.

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-08-01

The isoprenoid pathway produces three key metabolites--digoxin (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), dolichol (regulator of N-glycosylation of proteins), and ubiquinone (free radical scavenger). The isoprenoid pathway was assessed in patients with bronchial asthma. The pathway was also assessed in patients with right hemispheric, left hemispheric, and bihemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of bronchial asthma. The pathway was upregulated with increase in digoxin synthesis in bronchial asthma. There was an increase in tryptophan catabolites and a reduction in tyrosine catabolites in patients with bronchial asthma. The ubiquinone levels were low and lipid peroxidation increased in these patients. There was increase in dolichol and glycoconjugate levels and reduction in lysosomal stability in these patients. The cholesterol:phospholipid ratio was increased and glycoconjugate levels were reduced in the membranes of these patients. The patterns noticed in bronchial asthma were similar to those in patients with right hemispheric chemical dominance. Bronchial asthma occurs in right hemispheric chemically dominant individuals. Ninety percent of the patients with bronchial asthma were right-handed and left hemispheric dominant by the dichotic listening test. But their biochemical patterns were similar to those obtained in right hemispheric chemical dominance. Hemispheric chemical dominance is a different entity and has no correlation with handedness or the dichotic listening test.

Creation of Real Estate Based on Public Private Partnership and Municipal Private Partnership Agreements in the Russian Federation

Voronina, M. D.

2017-11-01

The article considers individual questions connected with the application of the legislation on public private partnership and municipal private partnership agreements as new types of contracts at the newly built property development. Public private partnership and municipal private partnership agreements are contracts at the initial development stage. Their objective is to attract investments in the Russian economy including for the creation of separate real estate types (capital facilities). The Law enables one to build the relationship in such a way that joint efforts result in the grounds for the accrual of the ownership right to the built (reconstructed) asset. This circumstance certainly influences the infrastructural development of the Russian Federation and its municipal units, the rather that it occurs due to the attraction of extra-budgetary sources

Full Text Available The partnership between the farmers and PT Galih Estetika Indonesia as the exporter company in the field of sweet potato processing is expected to support the development of sweet potato agribusiness in Kuningan Regency and become one of the solutions for farmers’ problems. Termination of partnership contracts undertaken by the farmers will have an impact on the implementation of partnerships, company operations as well as the value chain. This study aims to analyze the pattern of partnership, degree of partnership, value chain structure, value chain governance, farmers’ income (partner and non-partner and margin. The method of data processing and data analysis used the descriptive analysis qualitative and quantitative descriptive analysis. The results showed that the pattern of partnership that is formed is a centralized pattern with the degree value of partnership of 716 (madya pattern. The structure of the value chain by mapping the actors and their activities result in relationships and coordination between the parties. Farmers with companies belong to the modular type in VCG. Economic benefits indicate that net income of partner farmers is Rp22,157,828/Ha, while non-partner farmers obtain Rp12,306,789/Ha and the smallest margin is obtained by the coordinator. The analysis shows that farmers' incomes are larger, but partnership planning has not been ideal. Therefore, the roles of farmers, companies and related agencies are required in the running of the ideal sweet potato partnership program.Keywords: sweet potato partnership, partnership pattern, value chain, value chain governance, revenue

Hemispheric dominance underlying the neural substrate for learned vocalizations develops with experience.

Chirathivat, Napim; Raja, Sahitya C; Gobes, Sharon M H

2015-06-22

Many aspects of song learning in songbirds resemble characteristics of speech acquisition in humans. Genetic, anatomical and behavioural parallels have most recently been extended with demonstrated similarities in hemispheric dominance between humans and songbirds: the avian higher order auditory cortex is left-lateralized for processing song memories in juvenile zebra finches that already have formed a memory of their fathers' song, just like Wernicke's area in the left hemisphere of the human brain is dominant for speech perception. However, it is unclear if hemispheric specialization is due to pre-existing functional asymmetry or the result of learning itself. Here we show that in juvenile male and female zebra finches that had never heard an adult song before, neuronal activation after initial exposure to a conspecific song is bilateral. Thus, like in humans, hemispheric dominance develops with vocal proficiency. A left-lateralized functional system that develops through auditory-vocal learning may be an evolutionary adaptation that could increase the efficiency of transferring information within one hemisphere, benefiting the production and perception of learned communication signals.

2011-06-01

Full Text Available Abstract Background The extent to which partnership synergy is created within quality improvement programmes in the Netherlands is unknown. In this article, we describe the psychometric testing of the Partnership Self-Assessment Tool (PSAT among professionals in twenty-two disease-management partnerships participating in quality improvement projects focused on chronic care in the Netherlands. Our objectives are to validate the PSAT in the Netherlands and to reduce the number of items of the original PSAT while maintaining validity and reliability. Methods The Dutch version of the PSAT was tested in twenty-two disease-management partnerships with 218 professionals. We tested the instrument by means of structural equation modelling, and examined its validity and reliability. Results After eliminating 14 items, the confirmatory factor analyses revealed good indices of fit with the resulting 15-item PSAT-Short version (PSAT-S. Internal consistency as represented by Cronbach's alpha ranged from acceptable (0.75 for the 'efficiency' subscale to excellent for the 'leadership' subscale (0.87. Convergent validity was provided with high correlations of the partnership dimensions and partnership synergy (ranged from 0.512 to 0.609 and high correlations with chronic illness care (ranged from 0.447 to 0.329. Conclusion The psychometric properties and convergent validity of the PSAT-S were satisfactory rendering it a valid and reliable instrument for assessing partnership synergy and its dimensions of partnership functioning.

Brown, Louis D; Redelfs, Alisha H; Taylor, Thomas J; Messer, Reanna L

2015-09-01

Youth partnerships are a promising but understudied strategy for prevention and health promotion. Specifically, little is known about how the functioning of youth partnerships differs from that of adult partnerships. Accordingly, this study compared the functioning of youth partnerships with that of adult partnerships. Several aspects of partnership functioning, including leadership, task focus, cohesion, participation costs and benefits, and community support, were examined. Standardized partnership functioning surveys were administered to participants in three smoke-free youth coalitions (n = 44; 45 % female; 43 % non-Hispanic white; mean age = 13) and in 53 Communities That Care adult coalitions (n = 673; 69 % female; 88 % non-Hispanic white; mean age = 49). Multilevel regression analyses showed that most aspects of partnership functioning did not differ significantly between youth and adult partnerships. These findings are encouraging given the success of the adult partnerships in reducing community-level rates of substance use and delinquency. Although youth partnership functioning appears to be strong enough to support effective prevention strategies, youth partnerships faced substantially more participation difficulties than adult partnerships. Strategies that youth partnerships can use to manage these challenges, such as creative scheduling and increasing opportunities for youth to help others directly, are discussed.

Partnership duration, concurrency, and HIV in sub-Saharan Africa.

Science.gov (United States)

Sawers, Larry; Isaac, Alan

2017-07-01

A widely accepted explanation for the exceptionally high HIV prevalence in sub-Saharan Africa is the practice of long-term overlapping heterosexual partnering. This article shows that long-duration concurrent partnering can be protective against HIV transmission rather than promoting it. Monogamous partnering prevents sexual transmission to anyone outside the partnership and, in an initially concordant-seronegative partnership, prevents sexual acquisition of HIV by either partner. Those protections against transmission and acquisition last as long as the partnership persists without new outside partnerships. Correspondingly, these two protective effects characterise polygynous partnerships, whether or not the polygyny is formal or informal, until a partner initiates a new partnership. Stable and exclusive unions of any size protect against HIV transmission, and more durable unions provide a longer protective effect. Survey research provides little information on partnership duration in sub-Saharan Africa and sheds no light on the interaction of duration, concurrency, and HIV. This article shows how assumptions about partnership duration in individual-based sexual-network models affect the contours of simulated HIV epidemics. Longer mean partnership duration slows the pace at which simulated epidemics grow. With plausible assumptions about partnership duration and at levels of concurrency found in the region, simulated HIV epidemics grow slowly or not at all. Those results are consistent with the hypothesis that long-duration partnering is protective against HIV and inconsistent with the hypothesis that long-term concurrency drives the HIV epidemics in sub-Saharan Africa.

2018-06-01

The Rover Environmental Monitoring Station (REMS) on the Curiosity Rover is operating in the Southern Hemisphere of Mars and is detecting synoptic period oscillations in the pressure data that we attribute to Northern Hemisphere transient eddies. We base this interpretation on the similarity in the periods of the eddies and their seasonal variations with those observed in northern midlatitudes by Viking Lander 2 (VL-2) 18 Mars years earlier. Further support for this interpretation comes from global circulation modeling which shows similar behavior in the transient eddies at the grid points closest to Curiosity and VL-2. These observations provide the first in situ evidence that the frontal systems often associated with "Flushing Dust Storms" do cross the equator and extend into the Southern Hemisphere.

Hemispheric dominance and cell phone use.

A thorough understanding of why we hold a cell phone to a particular ear may be of importance when studying the impact of cell phone safety. To determine if there is an obvious association between sidedness of cell phone use and auditory hemispheric dominance (AHD) or language hemispheric dominance (LHD). It is known that 70% to 95% of the population are right-handed, and of these, 96% have left-brain LHD. We have observed that most people use their cell phones in their right ear. An Internet survey was e-mailed to individuals through surveymonkey.com. The survey used a modified Edinburgh Handedness Inventory protocol. Sample questions surveyed which hand was used to write with, whether the right or left ear was used for phone conversations, as well as whether a brain tumor was present. General community. An Internet survey was randomly e-mailed to 5000 individuals selected from an otology online group, patients undergoing Wada testing and functional magnetic resonance imaging, as well as persons on the university listserv, of which 717 surveys were completed. Determination of hemispheric dominance based on preferred ear for cell phone use. A total of 717 surveys were returned. Ninety percent of the respondents were right handed, and 9% were left handed. Sixty-eight percent of the right-handed people used the cell phone in their right ear, 25% in the left ear, and 7% had no preference. Seventy-two of the left-handed respondents used their left ear, 23% used their right ear, and 5% had no preference. Cell phone use averaged 540 minutes per month over the past 9 years. An association exists between hand dominance laterality of cell phone use (73%) and our ability to predict hemispheric dominance. Most right-handed people have left-brain LHD and use their cell phone in their right ear. Similarly, most left-handed people use their cell phone in their left ear. Our study suggests that AHD may differ from LHD owing to the difference in handedness and cell phone ear use

Hypothalamic digoxin and hemispheric chemical dominance: relation to speech and language dysfunction.

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-06-01

The isoprenoid pathway produces three key metabolites--endogenous digoxin, dolichol, and ubiquinone. Since endogenous digoxin can regulate neurotransmitter transport and dolichols can modulate glycoconjugate synthesis important in synaptic connectivity, the pathway was assessed in patients with dyslexia, delayed recovery from global aphasia consequent to a dominant hemispheric thrombotic infarct, and developmental delay of speech milestone. The pathway was also studied in right hemispheric, left hemispheric, and bihemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of speech disorders. The plasma/serum--activity of HMG CoA reductase, magnesium, digoxin, dolichol, ubiquinone--and tryptophan/tyrosine catabolic patterns, as well as RBC (Na+)-K+ ATPase activity, were measured in the above mentioned groups. The glycoconjugate metabolism and membrane composition was also studied. The study showed that in dyslexia, developmental delay of speech milestone, and delayed recovery from global aphasia there was an upregulated isoprenoidal pathway with increased digoxin and dolichol levels. The membrane (Na+)-K+ ATPase activity, serum magnesium and ubiquinone levels were low. The tryptophan catabolites were increased and the tyrosine catabolites including dopamine decreased in the serum contributing to a speech dysfunction. There was an increase in carbohydrate residues of glycoproteins, glycosaminoglycans, and glycolipids levels as well as an increased activity of GAG degrading enzymes and glyco hydrolases in the serum. The cholesterol:phospholipid ratio of RBC membrane increased and membrane glycoconjugates showed a decrease. All of these could contribute to altered synaptic inactivity in these disorders. The patterns correlated with those obtained in right hemispheric chemical dominance. Right hemispheric chemical dominance may play a role in the genesis of these disorders. Hemispheric chemical dominance has no correlation with handedness

The resection of left-sided perisylvian brain lesions harbors the risk of postoperative aphasia. Because it is known that language function can shift between hemispheres in brain tumor patients, the preoperative knowledge of the patient's language dominance could be helpful. We therefore investigated the hemispheric language dominance by repetitive navigated transcranial magnetic stimulation (rTMS) and surgery-related deficits of language function. We pooled the bicentric language mapping data of 80 patients undergoing the resection of left-sided perisylvian brain lesions in our two university neurosurgical departments. We calculated error rates (ERs; ER = errors per stimulations) for both hemispheres and defined the hemispheric dominance ratio (HDR) as the quotient of the left- and right-sided ER (HDR >1= left dominant; HDR right dominant). The course of the patient's language function was evaluated and correlated with the preoperative HDR. Only three of 80 patients (4%) presented with permanent surgery-related aphasia and 24 patients (30%) with transient surgery-related aphasia. The mean HDR (± standard deviation) of patients with new aphasia after five days was significantly higher (1.68±1.07) than the HDR of patients with no new language deficit (1.37±1.08) (p=0.0482). With a predefined cut-off value of 0.5 for HDR, we achieved a sensitivity for predicting new aphasia of 100%. A higher preoperative HDR significantly correlates with an increased risk for transient aphasia. Moreover, the intensive preoperative workup in this study led to a considerably low rate of permanent aphasia. Copyright © 2016 Elsevier Ltd. All rights reserved.

Teachers and their K-12 students lack firsthand experience in science research and often harbor misconceptions about science practices and the nature of science. To address this challenge, the NOAA-funded Student-Teacher-Researcher (STAR) partnership that provides rural high school students with authentic research experiences investigating the amount and sources of nitrate in schoolyard runoff. Teachers received training, guiding curricular materials aligned with NGSS and in-classroom support. With a focus on evidence-based reasoning skills, students actively participate in the research process through sample collection, data analysis, and an in-person discussion of conclusions and implications with our scientist team. As a member of this team, I assisted with refining the study design, analyzing nitrate isotope runoff samples, and sharing insights and feedback with students during the in-person discussion session. Assessment results indicate student gained an understanding of nitrate pollution and of science practices. As a graduate student, young scientist, and possessor of a B.S. in Science Education, I already recognized the value of involving K-12 students and teachers in authentic research experiences, as these experiences expose students to the nature of science while also improving content knowledge. During the STAR partnership, I learned firsthand some of the obstacles presented during outreach involving partnerships between a research institution and schools, such as inflexibility of school scheduling and the need for flexibility with research questions requiring complex lab analysis. Additionally, I discovered the challenge of working systemically across a school district, which can have broad impact but limit student experiences. Highlights of my experience included interactions with students and teachers, especially when students have unexpected answers to my questions, providing novel explanations for patterns observed in the data.

Full Text Available BACKGROUND: The existence and function of unilateral hemispheric projections within foveal vision may substantially affect foveal word recognition. The purpose of this research was to reveal these projections and determine their functionality. METHODOLOGY: Single words (and pseudowords were presented to the left or right of fixation, entirely within either foveal or extrafoveal vision. To maximize the likelihood of unilateral projections for foveal displays, stimuli in foveal vision were presented away from the midline. The processing of stimuli in each location was assessed by combining behavioural measures (reaction times, accuracy with on-line monitoring of hemispheric activity using event-related potentials recorded over each hemisphere, and carefully-controlled presentation procedures using an eye-tracker linked to a fixation-contingent display. PRINCIPAL FINDINGS: Event-related potentials 100-150 ms and 150-200 ms after stimulus onset indicated that stimuli in extrafoveal and foveal locations were projected unilaterally to the hemisphere contralateral to the presentation hemifield with no concurrent projection to the ipsilateral hemisphere. These effects were similar for words and pseudowords, suggesting this early division occurred before word recognition. Indeed, event-related potentials revealed differences between words and pseudowords 300-350 ms after stimulus onset, for foveal and extrafoveal locations, indicating that word recognition had now occurred. However, these later event-related potentials also revealed that the hemispheric division observed previously was no longer present for foveal locations but remained for extrafoveal locations. These findings closely matched the behavioural finding that foveal locations produced similar performance each side of fixation but extrafoveal locations produced left-right asymmetries. CONCLUSIONS: These findings indicate that an initial division in unilateral hemispheric projections occurs in

During the past decade active ageing has been positioned as a solution to the problem of global ageing. While the scientific, economic and even moral arguments for pursuing a more active old age has been many, the integration of active ageing in everyday practices face challenges. This chapter...... explores the ways that active ageing policies become part of everyday practices, by proposing the concept of active ageing technologies. Active ageing technologies are material and immaterial condensations of knowledge that form old age in specific ways. Through the cases of an innovation partnership, two...... activity centres and a billiards table, the author explores how active ageing policies are transformed in practice. The chapter draws on an ethnographic study of active ageing conducted at the two activity centres, as well as the author’s participation in the innovation partnership. The author uses...

Bulk stable isotope analysis provides information regarding food web interactions, and has been applied to several cetacean species for the study of migration ecology. One limitation in bulk stable isotope analysis arises when a species, such as Southern hemisphere humpback whales, utilises geographically distinct food webs with differing isotopic baselines. Migrations to areas with different baselines can result in isotopic changes that mimic changes in feeding relations, leading to ambiguous food web interpretations. Here, we demonstrate the novel application of radiocarbon measurement for the resolution of such ambiguities. Radiocarbon was measured in baleen plates from humpback whales stranded in Australia between 2007 and 2013, and in skin samples collected in Australia and Antarctica from stranded and free-ranging animals. Radiocarbon measurements showed lower values for Southern Ocean feeding than for extra-Antarctic feeding in Australian waters. While the whales mostly relied on Antarctic-derived energy stores during their annual migration, there was some evidence of feeding within temperate zone waters in some individuals. This work, to our knowledge, provides the first definitive biochemical evidence for supplementary feeding by southern hemisphere humpback whales within temperate waters during migration. Further, the work contributes a powerful new tool (radiocarbon) for tracing source regions and geographical feeding.

How to build science-action partnerships for local land-use planning and management: lessons from Durban, South Africa

Directory of Open Access Journals (Sweden)

Jessica Cockburn

2016-03-01

Full Text Available The gap between scientific knowledge and implementation in the fields of biodiversity conservation, environmental management, and climate change adaptation has resulted in many calls from practitioners and academics to provide practical solutions responding effectively to the risks and opportunities of global environmental change, e.g., Future Earth. We present a framework to guide the implementation of science-action partnerships based on a real-world case study of a partnership between a local municipality and an academic institution to bridge the science-action gap in the eThekwini Municipal Area, South Africa. This partnership aims to inform the implementation of sustainable land-use planning, biodiversity conservation, environmental management, and climate change adaptation practice and contributes to the development of human capacity in these areas of expertise. Using a transdisciplinary approach, implementation-driven research is being conducted to develop several decision-making products to better inform land-use planning and management. Lessons learned through this partnership are synthesized and presented as a framework of enabling actions operating at different levels, from the individual to the interorganizational. Enabling actions include putting in place enabling organizational preconditions, assembling a functional well-structured team, and actively building interpersonal and individual collaborative capacity. Lessons learned in the case study emphasize the importance of building collaborative capacity and social capital, and paying attention to the process of transdisciplinary research to achieve more tangible science, management, and policy objectives in science-action partnerships. By documenting and reflecting on the process, this case study provides conceptual and practical guidance on bridging the science-action gap through partnerships.

Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. © 2015 John Wiley & Sons, Ltd.

Diaci, J.; Kolar, U.

2000-01-01

Hemispherical photography represents one of the most appropriate methods of estimating averages of solar radiation over extended periods of time. This method is based upon the use of extremely wide-angle fisheye lenses, which produce large projection distortion. To correctly interpret hemispherical photography we have to know the projection characteristics of the fisheye lens in combination with a camera body. This can be achieved through lens calibration. The first part of the article explains in detail the calibration method for fisheye lenses which are used to assess the solar radiation in forest ecology research. In the second part the results of calibration for fisheye lens Sigma 8 mm, f/4 (MF, N) are presented. The lens was used on a Nikon F50 camera body

Co-production of knowledge: An Inuit Indigenous Knowledge perspective

Science.gov (United States)

Daniel, R.; Behe, C.

2017-12-01

A "co-production of knowledge" approach brings together different knowledge systems while building equitable and collaborative partnerships from `different ways of knowing.' Inuit Indigenous Knowledge is a systematic way of thinking applied to phenomena across biological, physical, cultural and spiritual systems; rooted with a holistic understanding of ecosystems (ICC Alaska 2016). A holistic image of Arctic environmental change is attained by bringing Indigenous Knowledge (IK) holders and scientists together through a co-production of knowledge framework. Experts from IK and science should be involved together from the inception of a project. IK should be respected as its own knowledge system and should not be translated into science. A co-production of knowledge approach is important in developing adaptation policies and practices, for sustainability and to address biodiversity conservation (Daniel et al. 2016). Co-production of knowledge is increasingly being recognized by the scientific community at-large. However, in many instances the concept is being incorrectly applied. This talk will build on the important components of co-production of knowledge from an Inuit perspective and specifically IK. In this presentation we will differentiate the co-production of knowledge from a multi-disciplinary approach or multi-evidence based decision-making. We underscore the role and value of different knowledge systems with different methodologies and the need for collaborative approaches in identifying research questions. We will also provide examples from our experiences with Indigenous communities and scientists in the Arctic. References: Inuit Circumpolar Council of Alaska. 2016.

Wang, Jiabao; Kim, Hye-Mi; Chang, Edmund K. M.

2018-03-01

Storm tracks, defined as the preferred regions of extratropical synoptic-scale disturbances, have remarkable impacts on global weather and climate systems. Causes of interannual storm track variation have been investigated mostly from a troposphere perspective. As shown in this study, Northern Hemisphere winter storm tracks are significantly modulated by the tropical stratosphere through the quasi-biennial oscillation (QBO). The North Pacific storm track shifts poleward during the easterly QBO winters associated with a dipole change in the eddy refraction and baroclinicity. The North Atlantic storm track varies vertically with a downward shrinking (upward expansion) in easterly (westerly) QBO winters associated with the change of the tropopause height. These results not only fill the knowledge gap of QBO-storm track relationship but also suggest a potential route to improve the seasonal prediction of extratropical storm activities owing to the high predictability of the QBO.

Variations and Regularities in the Hemispheric Distributions in Sunspot Groups of Various Classes

The present study investigates the variations and regularities in the distributions in sunspot groups (SGs) of various classes in the northern and southern hemispheres from Solar Cycles (SCs) 12 to 23. Here, we use the separation scheme that was introduced by Gao, Li, and Li ( Solar Phys. 292, 124, 2017), which is based on A/U ( A is the corrected area of the SG, and U is the corrected umbral area of the SG), in order to separate SGs into simple SGs (A/U ≤ 4.5) and complex SGs (A/U > 6.2). The time series of Greenwich photoheliographic results from 1875 to 1976 (corresponding to complete SCs 12 - 20) and Debrecen photoheliographic data during the period 1974 - 2015 (corresponding to complete SCs 21 - 23) are used to show the distributions of simple and complex SGs in the northern and southern hemispheres. The main results we obtain are reported as follows: i) the larger of the maximum annual simple SG numbers in the two hemispheres and the larger of the maximum annual complex SG numbers in the two hemispheres occur in different hemispheres during SCs 12, 14, 18, and 19; ii) the relative changing trends of two curves - cumulative SG numbers in the northern and southern hemispheres - for simple SGs are different from those for complex SGs during SCs 12, 14, 18, and 21; and iii) there are discrepancies between the dominant hemispheres of simple and complex SGs for SCs 12, 14, 18, and 21.

the aim of this study was to investigate specific activation patterns and potential gender differences during mental rotation and to investigate whether functional magnetic resonance imaging (fMRI) and functional transcranial Doppler sonography (fTCD) lateralize hemispheric dominance concordantly. regional brain activation and hemispheric dominance during mental rotation (cube perspective test) were investigated in 10 female and 10 male healthy subjects using fMRI and fTCD. significant activation was found in the superior parietal lobe, at the parieto-occipital border, in the middle and superior frontal gyrus bilaterally, and the right inferior frontal gyrus using fMRI. Men showed a stronger lateralization to the right hemisphere during fMRI and a tendency toward stronger right-hemispheric activation during fTCD. Furthermore, more activation in frontal and parieto-occipital regions of the right hemisphere was observed using fMRI. Hemispheric dominance for mental rotation determined by the 2 methods correlated well (P= .008), but did not show concordant results in every single subject. the neural basis of mental rotation depends on a widespread bilateral network. Hemispheric dominance for mental rotation determined by fMRI and fTCD, though correlating well, is not always concordant. Hemispheric lateralization of complex cortical functions such as spatial rotation therefore should be investigated using multimodal imaging approaches, especially if used clinically as a tool for the presurgical evaluation of patients undergoing neurosurgery.

Responsibilities and ethics is where organizations on bothsides would take on and accept their own norms, tasks, obligations and be aware that in a relationship there is a need to give explanations and justify one’s actions, such partnerships will be long and prosperous. This requires a great deal of knowledge and maturity together with a very important personal characteristic that is care. This study examines whether the creation of long term partnerships through responsible and more personal (friendlyrelations brings the organization to greater success.Purpose: The purpose of this research is to determine how important it is for organizations in the tourism industry to build long term relationships, what it should be based on and whether companies are willing to change the current methods of operations.Method: The method of research was an interview with individuals that had a certain position within a tourism company and had contacts with partners and were obligated to see out new ones. A paradigm model was built and the responses analysed.Results: The survey results are encouraging. The interviews showed that respondents were aware that it is necessary to have long term and responsible partnerships. They recognized that in today’s world there is a lack of collaboration that is based on understanding andthat there should be more relations on a personal level. It isrequired that this changes in the future. The participants specifically highlight financial irresponsibility in many companies that destroys collaboration.Organization: With the help of this study, the author attempts to contribute ideas to organizations on how to create solid collaboration with partners, as

2010-11-01

Full Text Available Previous analyses of the Earth’s annual cycle and its trends have utilized surface temperature data sets. Here we introduce a new analysis of the global and hemispheric annual cycle using a satellite remote sensing derived data set during the period 1979–2009, as determined from the lower tropospheric (LT channel of the MSU satellite. While the surface annual cycle is tied directly to the heating and cooling of the land areas, the tropospheric annual cycle involves additionally the gain or loss of heat between the surface and atmosphere. The peak in the global tropospheric temperature in the 30 year period occurs on 10 July and the minimum on 9 February in response to the larger land mass in the Northern Hemisphere. The actual dates of the hemispheric maxima and minima are a complex function of many variables which can change from year to year thereby altering these dates.Here we examine the time of occurrence of the global and hemispheric maxima and minima lower tropospheric temperatures, the values of the annual maxima and minima, and the slopes and significance of the changes in these metrics.  The statistically significant trends are all relatively small. The values of the global annual maximum and minimum showed a small, but significant trend. Northern and Southern Hemisphere maxima and minima show a slight trend toward occurring later in the year. Most recent analyses of trends in the global annual cycle using observed surface data have indicated a trend toward earlier maxima and minima.

Although conceptual definitions of person-centred care (PCC) vary, most models value the involvement of patients through patient-professional partnerships. While this may increase patients' sense of responsibility and control, research is needed to further understand how this partnership is created and perceived. This study aims to explore the realities of partnership as perceived by patients and health professionals in everyday PCC practice. Qualitative study employing a thematic analysis of semistructured interviews with professionals and patients. Four internal medicine wards and two primary care centres in western Sweden. 16 health professionals based at hospital wards or primary care centres delivering person-centred care, and 20 patients admitted to one of the hospital wards. Our findings identified both informal and formal aspects of partnership. Informal aspects, emerging during the interaction between healthcare professionals and patients, without any prior guidelines or regulations, incorporated proximity and receptiveness of professionals and building a close connection and confidence. This epitomised a caring, respectful relationship congruent across accounts. Formal aspects, including structured ways of sustaining partnership were experienced differently. Professionals described collaborating with patients to encourage participation, capture personal goals, plan and document care. However, although patients felt listened to and informed, they were content to ask questions and felt less involved in care planning, documentation or exploring lifeworld goals. They commonly perceived participation as informed discussion and agreement, deferring to professional knowledge and expertise in the presence of an empathetic and trusting relationship. In our study, patients appear to value a process of human connectedness above and beyond formalised aspects of documenting agreed goals and care planning. PCC increases patients' confidence in professionals who are

Who has a stake? How stakeholder processes influence partnership sustainability

Full Text Available As universities attempt to expand their relevance by engaging with local and regional societal challenges, various kinds of partnerships are emerging. A broad range of stakeholders, from both the university and the community, are typically engaged in and influence the development, implementation and perpetuation of these partnerships. This paper juxtaposes analysis of three community-university partnerships in Worcester, Massachusetts, USA, paying particular attention to the partnerships’ stakeholders, and to their relative importance. This research builds upon current understandings of critical factors in partnership sustainability, as these three partnerships have different goals, involve different university and community stakeholders, and are at different points in their organisational history. The fact that they share the same context – the same city – offers a unique opportunity for comparative case study analysis. The theory of stakeholder salience is used to explain findings about partnership sustainability and to make suggestions for strengthening existing partnerships. Specifically, we argue that stakeholder power and legitimacy, along with stakeholder urgency, are key factors in sustaining community-university partnerships.

Schell, M.C.; DeLuca, P.M. Jr.; Pearson, D.W.; Attix, F.H.

1980-01-01

A detector for the direct measurement of the Linear Energy Transfer (LET) in cylindrical geometry was developed by Brandan and DeLuca. The detector successfully measured the LET of protons and a fraction of the heavy charged particles generated in cylindrical A150 plastic and graphite walls by 14.8 MeV neutrons. In this report, we present design tests for the hemispherical LET detector which will measure the LET of charged particles in spherical geometry and allow comparison with calculated LET spectra. The hemispherical LET detector will also provide a data base for radiobiological predictions with the Track Structure Model by Katz. A comparison of predictions of radiobiological effects by the Theory of Dual Radiation Action and the Track Structure Model by Edwards and the authors indicate that the Track Structure Model predicts cell survival as a function of dose more accurately and hence an additional motivation for the present construction of the hemispherical LET detector

Experimental Study on CHF in a Hemispherical Narrow Gap

1999-01-01

As a part of the SONATA-IV program, KAERI is conducting an experimental investigation of critical heat flux(CHF) in hemispherical narrow gaps. A visualization experiment, VISU-II, was done as the first step to get a visual observation of the flow behaviour inside a hemispherical gap and to understand the CHF-triggering mechanism. It was observed that the counter-current flow limitation (CCFL) phenomenon prevented water from wetting the heater surface and induced CHF. The CHFG (Critical Heat Flux in Gap) test is now being performed to measure the CHF and to investigate the inherent cooling mechanism in hemispherical narrow gaps. Temperature measurements over the heater surface show that the two-phase flow behaviour inside the gaps could be quite different from the other usual CHF experiments. The measured CHF points are lower than the predictions by existing empirical correlations based on the data measured with small-scale horizontal plates and vertical annulus. (authors)

Full Text Available Abstract This paper examines the challenges and opportunities in establishing and sustaining north–south research partnerships in Africa through a case study of the UK-Africa Academic Partnership on Chronic Disease. Established in 2006 with seed funding from the British Academy, the partnership aimed to bring together multidisciplinary chronic disease researchers based in the UK and Africa to collaborate on research, inform policymaking, train and support postgraduates and create a platform for research dissemination. We review the partnership’s achievements and challenges, applying established criteria for developing successful partnerships. During the funded period we achieved major success in creating a platform for research dissemination through international meetings and publications. Other goals, such as engaging in collaborative research and training postgraduates, were not as successfully realised. Enabling factors included trust and respect between core working group members, a shared commitment to achieving partnership goals, and the collective ability to develop creative strategies to overcome funding challenges. Barriers included limited funding, administrative support, and framework for monitoring and evaluating some goals. Chronic disease research partnerships in low-income regions operate within health research, practice, funding and policy environments that prioritise infectious diseases and other pressing public health and developmental challenges. Their long-term sustainability will therefore depend on integrated funding systems that provide a crucial capacity building bridge. Beyond the specific challenges of chronic disease research, we identify social capital, measurable goals, administrative support, creativity and innovation and funding as five key ingredients that are essential for sustaining research partnerships.

Right-hemispheric processing of non-linguistic word features: implications for mapping language recovery after stroke.

Verbal stimuli often induce right-hemispheric activation in patients with aphasia after left-hemispheric stroke. This right-hemispheric activation is commonly attributed to functional reorganization within the language system. Yet previous evidence suggests that functional activation in right-hemispheric homologues of classic left-hemispheric language areas may partly be due to processing nonlinguistic perceptual features of verbal stimuli. We used functional MRI (fMRI) to clarify the role of the right hemisphere in the perception of nonlinguistic word features in healthy individuals. Participants made perceptual, semantic, or phonological decisions on the same set of auditorily and visually presented word stimuli. Perceptual decisions required judgements about stimulus-inherent changes in font size (visual modality) or fundamental frequency contour (auditory modality). The semantic judgement required subjects to decide whether a stimulus is natural or man-made; the phonologic decision required a decision on whether a stimulus contains two or three syllables. Compared to phonologic or semantic decision, nonlinguistic perceptual decisions resulted in a stronger right-hemispheric activation. Specifically, the right inferior frontal gyrus (IFG), an area previously suggested to support language recovery after left-hemispheric stroke, displayed modality-independent activation during perceptual processing of word stimuli. Our findings indicate that activation of the right hemisphere during language tasks may, in some instances, be driven by a "nonlinguistic perceptual processing" mode that focuses on nonlinguistic word features. This raises the possibility that stronger activation of right inferior frontal areas during language tasks in aphasic patients with left-hemispheric stroke may at least partially reflect increased attentional focus on nonlinguistic perceptual aspects of language.

[Sex differences in relationship between creativity and hemispheric information processing in global and local levels].

Razumnikova, O M; Vol'f, N V

2012-01-01

Sex differences in creativity related global-local hemispheric selective processing were examined by hierarchical letter presenting in conditions of their perception and comparison. Fifty-six right-handed males and 68 females (aged 17-22 years) participated in the experiments. Originality-imagery was assessed by a computer-based Torrance 'Incomplete Figures' test software. Verbal creativity was valued by original sentence using of three nouns from remote semantic categories. The results show that irrespectively of the sex factor and the type of creative thinking, its originality is provided by high speed of right-hemispheric processes of information selection on the global level and delay in the interhemispheric communication. Relationships between originality of ideas and hemispheric attentional characteristics are presented mostly in men while verbal creative problem solving, and in women while figurative original thinking. Originality of verbal activity in men is more associated with success of selective processes in the left hemisphere, but in women--with selective functions of both hemispheres. Figurative thinking in men is less related to hemispheric characteristics of attention compared with women. Increase of figurative originality in women is accompanied acceleration of processes of selection of the information in the right hemisphere, and also higher efficiency of local attention as well as speeds ofglobal processing in the left hemisphere.

A major goal of the Medical Education Partnership Initiative (MEPI) is to improve local health systems by strengthening medical education in Sub-Saharan Africa. A new approach to collaboration was intended to overcome the one-sided nature of many partnerships that often provide more rewards to institutions from wealthy countries than to their Sub-Saharan African counterparts. The benefits of this MEPI approach are reflected in at least five positive outcomes. First, effective partnerships have been developed across a diverse group of MEPI stakeholders. Second, a "community of practice" has been established to continue strengthening medical education in Sub-Saharan Africa. Third, links have been strengthened among MEPI health science schools in Sub-Saharan Africa, their communities, and ministries of both health and education. Fourth, respect among partners in the United States for a culture of ownership and self-determinism among their African counterparts committed to improving education has been enhanced. And finally, performance metrics for strengthening of health science education in Sub-Saharan Africa have been advanced. Meanwhile, partner medical schools in the United States have witnessed the benefits of collaborating across traditional disciplinary boundaries, such as physicians working within highly functioning community-based health care teams with many of the participating schools in Sub-Saharan Africa. MEPI demonstrates that North-South as well as South-South partnerships, with an explicit focus on improving local health systems through better education, can be designed to empower partners in the South with support from collaborators in the North.

NASA senior management has identified the need to develop a strategy for increased contracting with the historically black colleges and universities (HBCUs) and other minority universities (OMUs). The benefits to the institutions, by partnering with NASA, include developing their industrial base via NASA-industry partnerships, strong competitive advantage in technology-based research opportunities, and improved research capabilities. NASA gains increased contributed value to the Agency missions and programs as well as potential future recruits from technology-trained students who also constitute a pool for the nation s workforce. This report documents synergistic links between Glenn Research Center research and technology programs and faculty expertise at HBCUs and OMUs. The links are derived, based on Glenn technologies in the various directorates, program offices, and project offices. Such links readily identify universities with faculty members who are knowledgeable or have backgrounds in the listed technologies for possible collaboration. Recommendations are made to use the links as opportunities for Glenn and NASA, as well as industry collaborators, to cultivate stronger partnerships with the universities. It is concluded that Glenn and its partners and collaborators can expect to mutually benefit from leveraging NASA s cutting-edge and challenging research and technologies; industry's high technology development, research and development facilities, system design capabilities and market awareness; and academia s expertise in basic research and relatively low overhead cost. Reduced cost, accelerated technology development, technology transfer, and infrastructure development constitute some of the derived benefits.

The study of risk preference has become a widely investigated area of research. The current study is designed to investigate the relationship between handedness, hemispheric predominance and valence imposition in a risky-choice decision task. Research into the valence hypothesis (e.g., Ahern & Schwartz, 1985; Davidson, 1984) has shown that the left hemisphere is more active in processing positively valenced stimuli, whereas the right hemisphere is more active in processing negatively valenced stimuli. A total of 520 individuals (343 female, 117 male) participated in a self-imposed framing task and took a degree of handedness questionnaire. The results of the framing task and handedness questionnaire showed that participants' degree of handedness significantly influenced the positive/negative valence they imposed onto the framing task as well as their level of risk preference.

Exploring educational partnerships: a case study of client provider technology education partnerships in New Zealand primary schools

Science.gov (United States)

Weal, Brenda; Coll, Richard

2007-04-01

This paper explores the notion of educational partnerships and reports on research on client provider partnerships between full primary schools and external technology education providers for Year 7 and 8 New Zealand students (age range approx. 12 to 13 years). Educational reforms in New Zealand and the introduction of a more holistic technology education curriculum in 1995 changed the nature of the relationship between the technology education partners. The research sought to identify, from the perspective of the primary schools (clients), factors that contribute to successful partnerships between them and their technology education provider. A mixed methods approach consisting of a survey of client schools, in-depth interviews and a series of four in-depth case studies (drawing on issues derived from the survey) was employed. Issues relating to teacher subculture, leadership roles and inflexibility of official processes all surfaced. The research points to an absence of commitment, shared understanding, shared power, leadership, communication and accountability in many educational partnerships that were the focus of this work.

2017-07-01

To investigate the ability of transcranial magnetic stimulation (TMS) outcomes in the chronic stroke population to (i) track individual plastic changes and (ii) detect differences between individuals. To this end, intrarater "test-retest" reliability (relative and absolute) was tested for the ipsilesional and contralesional hemispheres. Thirteen participants with a unilateral stroke (≥6months ago) and sensorimotor impairments were enrolled. Single and paired-pulse TMS outcomes were obtained from the primary motor cortex (M1) representation of the tibialis anterior muscle in both hemispheres and at two sessions separated by one week. The standard error of the measurement (SEM eas ), minimal detectable change (MDC) and intraclass correlation coefficient (ICC) were studied. Active motor threshold and latency of motor evoked potentials provided the lowest SEM eas and highest ICCs for both ipsi- and contralesional hemispheres. However, MDC were generally large, thus questioning the use of TMS outcomes to track individual plastic changes of M1. Our study provided supporting evidence of good to excellent intrarater reliability for a few TMS outcomes and proposed recommendations on the interpretation and the use of that knowledge in future work. Psychometric properties of TMS measures should be further addressed in order to better understand how to refine their use in clinical settings.

Hemispherical photography to estimate biophysical variables of cotton

Directory of Open Access Journals (Sweden)

Ziany N. Brandão

Full Text Available ABSTRACT The Leaf Area Index (LAI is a key parameter to evaluate the vegetation spectral response, estimating plant nutrition and water requirements. However, in large fields is difficult to obtain accurate data to LAI determination. Therefore, the objective of this study was the estimation of LAI, biomass and yield of irrigated cotton through digital hemispherical photography. The treatments consisted of four nitrogen doses (0, 90, 180 and 270 kg ha-1 and four phosphorus doses (0, 120, 240 and 360 kg ha-1. Digital hemispherical photographs were collected under similar sky brightness conditions at 60 and 75 days after emergence (DAE, performed by the Digital Plant Canopy Imager - CI-110® of CID Inc. Biomass and LAI measurements were made on the same dates. LAI was also determined by destructive and non-destructive methods through a leaf area integrator (LI-COR® -LI-3100C model, and by measurements based on the midrib length of all leaves, respectively. The results indicate that the hemispherical images were appropriate to estimate the LAI and biomass production of irrigated cotton, while for the estimation of yield, more research is needed to improve the method.
