Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space mi...

This study investigated the relations between maternal and paternal rearing practices and adolescents' depressive symptoms, and whether time perspective in adolescence explains these links. The sample included 306 students (158 girls), aged between 10.83 and 14.42 years. Adolescents completed questionnaires assessing their perceptions of maternal and paternal acceptance and psychological control, and of their future time perspective and depressive symptoms. Adolescents who rated their mothers as more accepting and those who rated their fathers as less psychologically controlling also reported lower levels of depressive symptoms and greater future time perspective. Further, adolescents who had greater future time perspective reported lower levels of depressive symptoms. Finally, time perspective partially mediated the relations of maternal and paternal acceptance, and paternal control with depressive symptoms in adolescence. The findings highlight the unique relations of maternal acceptance and paternal psychological control with adolescents' depressive symptoms, and that future time perspective is one mechanism that might explain why parenting strategies are linked with depressive symptoms in adolescence.

This article identifies different stakeholder perspectives on future flood management in the downstream parts of the Rhine basin in Germany and The Netherlands. The perspectives were identified using Q methodology, which proved to be a good, but time-intensive, method for eliciting and analyzing stakeholder perspectives in a structured and unbiased way. Three shared perspectives were found: A) "Anticipation and institutions", B) "Space for flooding" and C) "Knowledge and engineering". These three perspectives share a central concern for the provision of safety against flooding, but disagree on the expected autonomous developments and the preferred measures. In perspective A, the expected climate change and economic growth call for fast action. To deal with the increasing flood risk, mostly institutional measures are proposed, such as the development of a stronger basin commission. In perspective B, an increasing spatial pressure on the river area is expected, and the proposed measures are focused on mitigating damage, e.g., through controlled flooding and compartmentalization. In perspective C, the role of expert knowledge and technological improvements is emphasized. Preferred strategies include strengthening the dikes and differentiation of safety standards. An overview of stakeholder perspectives can be useful in natural resources management for 1) setting the research agenda, 2) identifying differences in values and interests that need to be discussed, 3) creating awareness among a broad range of stakeholders, and 4) developing scenarios.

Attentional bias for emotional information in older adults: the role of emotion and future time perspective.

Research suggests that older adults display a positivity bias at the level of information processing. However, because studies investigating attentional bias for emotional information in older adults have produced mixed findings, research identifying inter-individual differences that may explain these inconsistent results is necessary. Therefore, we investigated whether mood, symptoms of depression, symptoms of anxiety and future time perspective are related to attentional bias in older adults. Thirty-seven healthy older adults and 25 healthy middle-aged adults completed questionnaires to assess mood, symptoms of depression, symptoms of anxiety and future time perspective. Attentional bias towards happy, sad and neutral information was measured using a modified exogenous cueing paradigm with long cue presentations, to measure maintained attention versus avoidance of emotional stimuli. Older adults showed attentional avoidance for all emotional faces, whereas no attentional biases were found in the middle-aged group. Moreover, in the older adult group, avoidance for negative information was related to anxiety. Future time perspective was unrelated to attentional bias. These findings suggest that anxiety may lead to inter-individual differences in attentional bias in older adults, and that avoidance from negative information may be an emotion regulation strategy.

An interest exists in understanding why adolescents partake in risky sexual behaviours, as well as the risk and protective practices associated with risky sexual behaviour. The aim of this study was to investigate the moderator effect of future time perspective in the relationship between self-efficacy and risky sexual behaviour. A random cluster consisting of 467 learners from English medium high schools of central South Africa participated in this study. The participants' risky sexual behaviour, self-efficacy and future time perspective were measured with the Perceptions of HIV/AIDS Risk Survey, Generalised Perceived Self-efficacy Scale and the Zimbardo Time Perspective Inventory, respectively. Product term regression analysis was performed. It was found that both self-efficacy and future time perspective were negatively related to risky sexual behaviour. No moderating effect was found for future time perspective in the relationship between self-efficacy and risky sexual behaviour. Self-efficacy and future time perspective were identified as qualities that protect adolescents from engaging in risky sexual behaviours. This finding can be useful in developing prevention programmes. Intervention programmes aimed at the youth should foster a sense of hope and possibility about the future and the development of goals and aspirations to prevent risky behaviour.

Perspectives on the future of the electric utility industry

This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ''business as usual,'' ''technotopia future,'' and ''fortress state'' -and three electric utility scenarios- ''frozen in headlights,'' ''megaelectric,'' and ''discomania.'' The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest

Career maturity is an important parameter as nursing undergraduates prepare for their future careers. However, little is known regarding the relationships between attributions, future time perspective and career maturity among nursing undergraduates. The purpose of this study was to investigate the degree of career maturity and its relationship with attributions and future time perspective. A cross-sectional survey was designed. This survey was administered to 431 Chinese nursing undergraduates. Independent-sample t-tests and one-way ANOVA were performed to examine the mean differences between categories of binary and categorical demographic characteristics, respectively. Pearson correlations and multiple linear regressions were used to test the relationships between attributions, future time perspective and career maturity. The degree of career maturity was moderate among nursing undergraduates and that internal attributions of academic achievement, future efficacy and future purpose consciousness were positively associated with career maturity (all p time perspective and to facilitate their transition from school to clinical practice.

Full Text Available Previous research (Omar, 2005; Omar, Uribe Delgado & Maltaneres, 2005, had showed a clear relationship between subjective well-being and resilience. In those opportunities, however, resilience was considered as a global construct. This study aims at exploring the possible relationships among resilience components, subjective well-being, and future perspectives. Method: Sample integrated by 198 (105 girls & 93 boys Argentinean high school students, 14- to 19-yr.-old. All sample participants answered a booklet that included Wagnild and Young’s Resilience Scale (1993; Nagpal and Sell’s Subjective Well-being Scale (1992, and three items specially developed to explore academic, labor, and family future perspectives. Development: correlation analysis indicated positive significant associations between resilience’s components (Personal realization; Self- determination, and Adaptation, and specific well-being dimensions. Likewise, resilience’s components and subjective well being dimensions showed significant correlations with positive future perspectives. No gender-specific differences were observed in any of the variables under analysis. Results: findings showed that adolescent resilience would be associated to familiar emotional support and positive social interchanges. Future orientations could be considered a new resilience protective factor. Social, familiar, and educational implications of these finding are discussed. A research agenda designed to further our understanding of resilience, well-being, and future perspectives linkages is proposed.

Medical curricula should focus on the future of health care. Contemporary competency frameworks for curriculum design such as Canadian Medical Education Directions for Specialists (CanMEDS), ACGME and Tomorrow's Doctors share this vision by stressing generic competencies. The objective of this study was to investigate how well a contemporary competency framework fits in with clinicians' perspectives on future health care. Using a strategic planning approach, a semi-structured open-ended questionnaire on the future of their profession was sent to 102 Dutch gynecologists. Through inductive analysis, a future perspective and its needed competencies were identified and compared to the CanMEDS framework. The 62 responses showed content validity for the CanMEDS roles. Additionally, two roles were identified: advanced technology user and entrepreneur. Within the role Communicator, the focus will change through more active patient participation. The roles Collaborator and Manager are predicted to change in focus because of an increase of complex interdisciplinary teamwork and leadership roles. By studying the Dutch gynecologists' perspective of the future in a strategic planning approach, two additional roles and focus areas within a contemporary competency framework were identified. The perspective of clinicians on future health care provides valuable messages on how to design future-proof curricula.

Adolescent boys are characterised by increased risk-taking behavior, including a relatively high propensity to develop problem gambling habits. The association between gambling and sensitivity to immediately available rewards is well-established, suggesting that gamblers are less influenced by potential future consequences than non-gamblers. Nevertheless, existing studies have considered present- and future-orientation as two ends of the same continuum, and have not investigated the possibility that present and future perspectives might make independent contributions to gambling behavior. In the current study, we adopted Zimbardo's multidimensional approach, which discriminates between not only present and future perspectives, but also between a hedonistic and fatalistic present-orientation (in addition to positive and negative orientations towards the past). The participants were 223 male adolescents (mean age = 16.7 years). We investigated the effects of time perspectives on gambling frequency and gambling problem severity, after taking into account the effects of age, sensation seeking, and gambling-related cognitive distortions. Gambling frequency was significantly predicted by the present fatalistic perspective, and problem gambling was significantly (negatively) related to the future perspective. The present hedonistic and past negative perspectives were also significantly related to both gambling frequency and gambling problems, although they did not explain additional variance in gambling behavior when the effects of the other factors were controlled. Overall, these results offer a fresh perspective on the role of time perspectives in gambling behavior, with potential implications for understanding the origins of gambling problems and the development of novel interventions.

A core construct in the lifespan theory of socioemotional selectivity, future time perspective (FTP) refers to individuals’ perceptions of their remaining time in life. Its adaptation to the work context, occupational future time perspective (OFTP), entails workers’ perceptions of remaining time and opportunities in their careers. Over the past decade, several quantitative studies have investigated antecedents and consequences of general FTP and OFTP in the work context (i.e., FTP at work). We systematically review and critically discuss this literature on general FTP (k = 17 studies) and OFTP (k = 16 studies) and highlight implications for future research and practice. Results of our systematic review show that, in addition to its strong negative relationship with age, FTP at work is also associated with other individual (e.g., personality traits) and contextual variables (e.g., job characteristics). Moreover, FTP at work has been shown to mediate and moderate relationships of individual and contextual antecedents with occupational well-being, as well as motivational and behavioral outcomes. As a whole, findings suggest that FTP at work is an important variable in the field of work and aging, and that future research should improve the ways in which FTP at work is measured and results on FTP at work are reported.

2007-01-01

We discuss the ability of the nation's measurement system to meet future metrology needs of the semiconductor industry. Lacking an acceptable metric for assessing the health of metrology for the semiconductor industry, we identify a limited set of unmet measurement needs. Assuming that this set of needs may serve as proxy for the galaxy of semiconductor measurement needs, we examine it from the perspective of what will be required to continue the semiconductor industry's powerful impact in the world's macro-economy and maintain its exceptional record of numerous technological innovations. This paper concludes with suggestions about ways to strengthen the measurement system for the semiconductor industry.

Are larks future-oriented and owls present-oriented? Age- and sex-related shifts in chronotype-time perspective associations.

Science.gov (United States)

Nowack, Kati; van der Meer, Elke

2013-12-01

The chronotype (morningness/eveningness) relates to individual differences in circadian preferences. Time perspective (past, present, future) refers to the preference to rely on a particular temporal frame for decision-making processes and behavior. First evidence suggests that future time perspective is associated with greater morningness and present time perspective with greater eveningness. However, little is known about how chronotype-time perspective relationships may alter over the life span. This present study investigated links between chronotype and time perspective more thoroughly by taking age and sex into account as well. Seven hundred six participants aged between 17 and 74 completed German adaptations of the Morningness--Eveningness Questionnaire (MEQ) and Zimbardo Time Perspective Inventory (ZTPI). Controlling for age and sex, relationships between morningness and future time perspective as well as between eveningness and present time perspective were replicated. These findings were supported by significant associations between time perspective and midpoint of sleep. Future time perspective was linked to earlier midpoints of sleep, indicating an early chronotype. Present time perspective was associated with later midpoints of sleep, indicating a late chronotype. However, age and sex had an impact on the chronotype-time perspective relationships. In all age groups, male larks were more future-oriented and less present-oriented, male owls more present-oriented and less future-oriented. The same conclusion could be drawn for female adolescents and young adults. For female adults above 30, there was no interrelationship between morningness and future time perspective but between eveningness and past time perspective. Female adult owls were more present-oriented as well as more past-oriented. Female adult larks were less present-oriented and less past-oriented. Findings are discussed in the light of neuroendocrine and serotonergic functioning.

Mobile Device Security: Perspectives of Future Healthcare Workers.

Hewitt, Barbara; Dolezel, Diane; McLeod, Alexander

2017-01-01

Healthcare data breaches on mobile devices continue to increase, yet the healthcare industry has not adopted mobile device security standards. This increase is disturbing because individuals are often accessing patients' protected health information on personal mobile devices, which could lead to a data breach. This deficiency led the researchers to explore the perceptions of future healthcare workers regarding mobile device security. To determine healthcare students' perspectives on mobile device security, the investigators designed and distributed a survey based on the Technology Threat Avoidance Theory. Three hundred thirty-five students participated in the survey. The data were analyzed to determine participants' perceptions about security threats, effectiveness and costs of safeguards, self-efficacy, susceptibility, severity, and their motivation and actions to secure their mobile devices. Awareness of interventions to protect mobile devices was also examined. Results indicate that while future healthcare professionals perceive the severity of threats to their mobile data, they do not feel personally susceptible. Additionally, participants were knowledgeable about security safeguards, but their knowledge of costs and problems related to the adoption of these measures was mixed. These findings indicate that increasing security awareness of healthcare professionals should be a priority.

Göllner, Lars M; Ballhausen, Nicola; Kliegel, Matthias; Forstmeier, Simon

2017-01-01

The delay of gratification (DoG) in children is widely investigated with an experimental procedure originally called the "marshmallow test," whereas the studies on self-regulation (SR) in adolescents and adults usually use self-report questionnaires. Delay discounting (DD) measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences in DoG and DD from childhood to old age using a test that is suitable for both children and adults. Furthermore, investigations were conducted on the association between DoG/DD and two future orientation constructs [future time perspective (FTP) and episodic future thinking (EFT)] as well as age differences in these constructs. Participants from five age groups (9-14, 18-25, 35-55, 65-80, 80+) participated in the study ( N = 96). While we found no age difference for DoG, DD was the lowest [i.e., self-control (SC) was the highest] in young/middle adults; however, it was the highest (i.e., SC was the lowest) in children and old/oldest adults. Furthermore, we found significant age differences for DD and FTP. As predicted, there were strong correlations between DoG and FTP and between DD and FTP, but not between DoG/DD and EFT. These results indicate that age differences in SR vary across the measures used. Individuals who generally think and act in a future-oriented manner have a stronger ability to delay gratification.

Full Text Available Maritime transportation is one of the indicator and determining sectors of state economies. It’s shaped in parallel with the economic structure of the coastal countries in increasing or decreasing volumes. Especially with a significant advantage in international trade, sea transport is increasingly been competitive with other modes of transport. Considering the geographic location of Turkey, evaluating from criticial perspectives and developing meaningful proposals for effective solutions to such issues as strenghtening the alternative routes in seaborne trade and privitazing the ports that are to make further technological investments will enable to take effective and proactive measures concerning the future of this industry. In this study, the existing and likely expansions in the structure of shipping industry both in Turkey and in the world have been examined. In this examination, certain secondary data sets, such as the relevant literature and the recent statistical data, have been used.

The Subjective Health Horizon Questionnaire (SHH-Q): Assessing Future Time Perspectives for Facets of an Active Lifestyle.

A wider subjective time horizon is assumed to be positively associated with longevity and vitality. In particular, a lifestyle with exposure to novel and varied information is considered beneficial for healthy cognitive aging. At present, measures that specifically assess individuals' perceived temporal extension to engage in active lifestyles in the future are not available. We introduce and validate a new self-report measure, the Subjective Health Horizon Questionnaire (SHH-Q). The SHH-Q assesses individuals' future time perspectives in relation to four interrelated but distinct lifestyle dimensions: (1) novelty-oriented exploration (Novelty), (2) bodily fitness (Body), (3) work goals (Work), and (4) goals in life (Life Goals). The present study aims at: (a) validating the hypothesized factor structure of the SHH-Q, according to which the SHH-Q consists of four interrelated but distinct subscales, and (b) testing the hypothesis that the Novelty and Body subscales of the SHH-Q show positive and selective associations with markers of cognition and somatic health, respectively. Using structural equation modeling, we analyzed data from 1,371 healthy individuals (51% women) with a mean age of 70.1 years (SD = 3.6) who participated in the Berlin Aging Study II (BASE-II) and completed the SHH-Q. As predicted, the SHH-Q formed four correlated but distinct subscales: (1) Novelty, (2) Body, (3) Work, and (4) Life Goals. Greater self-reported future novelty orientation was associated with higher current memory performance, and greater future expectations regarding bodily fitness with better current metabolic status. The SHH-Q reliably assesses individual differences in four distinct dimensions of future time perspective. Two of these dimensions, Novelty and Body, show differential associations with cognitive status and somatic health. The SHH-Q may serve as a tool to assess how different facets of future time perspective relate to somatic health, cognition, motivation, and

Science.gov (United States)

Krücken, R.

2001-07-01

The recoil distance method (RDM) for measuring pico-second nuclear level lifetimes and its use in nuclear structure studies is reviewed and perspectives for the future are presented. High precision measurements in the mass-130 region, studies of multi-phonon states in rare earth nuclei, the investigation of shape coexistence and the recently discovered phenomenon of "magnetic rotation" are reviewed. Prospects for lifetime measurements in exotic regions of nuclei such as the measurement of lifetimes in neutron rich nuclei populated via spontaneous and heavy-ion induced fission are discussed. Other prospects include the use of the RDM technique in conjunction with recoil separators. The relevance of these techniques for experiments with radioactive ion beams will be discussed.

CT myocardial perfusion imaging: current status and future perspectives.

Science.gov (United States)

Yang, Dong Hyun; Kim, Young-Hak

2017-07-01

Computed tomography myocardial perfusion (CTP) combined with coronary computed tomography angiography (CCTA) may constitute a "1-stop shop" for the noninvasive diagnosis of hemodynamically significant coronary stenosis during a single CT examination. CTP shows high diagnostic performance and provides incremental value over CCTA for the detection of hemodynamically significant coronary stenosis in patients with a high Agatston calcium score or coronary artery stents. Future studies should determine the optimal protocol and clinical value of CTP for guiding revascularization strategy and prognostication. In this article, we review the current status and future perspectives of CTP, focusing on technical considerations, clinical applications, and future research topics.

Future versus present: time perspective and pupillary response in a relatedness judgment task investigating temporal event knowledge.

Science.gov (United States)

Nowack, Kati; Milfont, Taciano L; van der Meer, Elke

2013-02-01

Mental representations of events contain many components such as typical agents, instruments, objects as well as a temporal dimension that is directed towards the future. While the role of temporal orientation (chronological, reverse) in event knowledge has been demonstrated by numerous studies, little is known about the influence of time perspective (present or future) as source of individual differences affecting event knowledge. The present study combined behavioral data with task-evoked pupil dilation to examine the impact of time perspective on cognitive resource allocation. In a relatedness judgment task, everyday events like raining were paired with an object feature like wet. Chronological items were processed more easily than reverse items regardless of time perspective. When more automatic processes were applied, greater scores on future time perspective were associated with lower error rates for chronological items. This suggests that a match between a strong focus on future consequences and items with a temporal orientation directed toward the future serves to enhance responding accuracy. Indexed by pupillary data, future-oriented participants invested more cognitive resources while outperforming present-oriented participants in reaction times across all conditions. This result was supported by a principal component analysis on the pupil data, which demonstrated the same impact of time perspective on the factor associated with more general aspects of cognitive effort. These findings suggest that future time perspective may be linked to a more general cognitive performance characteristic that improves overall task performance. Copyright © 2012 Elsevier B.V.

Delay of Gratification, Delay Discounting and their Associations with Age, Episodic Future Thinking, and Future Time Perspective

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available The delay of gratification (DoG in children is widely investigated with an experimental procedure originally called the “marshmallow test,” whereas the studies on self-regulation (SR in adolescents and adults usually use self-report questionnaires. Delay discounting (DD measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences in DoG and DD from childhood to old age using a test that is suitable for both children and adults. Furthermore, investigations were conducted on the association between DoG/DD and two future orientation constructs [future time perspective (FTP and episodic future thinking (EFT] as well as age differences in these constructs. Participants from five age groups (9–14, 18–25, 35–55, 65–80, 80+ participated in the study (N = 96. While we found no age difference for DoG, DD was the lowest [i.e., self-control (SC was the highest] in young/middle adults; however, it was the highest (i.e., SC was the lowest in children and old/oldest adults. Furthermore, we found significant age differences for DD and FTP. As predicted, there were strong correlations between DoG and FTP and between DD and FTP, but not between DoG/DD and EFT. These results indicate that age differences in SR vary across the measures used. Individuals who generally think and act in a future-oriented manner have a stronger ability to delay gratification.

The present study aimed to investigate the moderating effect of age on the relationship between future time perspective (FTP) and future-oriented coping. A total of 1,915 participants aged 9-84 years completed measures of FTP and future-oriented coping. Moderation analyses were conducted to examine whether age played a role in the association between FTP and future-oriented coping (proactive and preventive). Results showed that proactive and preventive coping were negatively correlated with age, and age moderated the association between FTP and preventive coping but not proactive coping. Furthermore, the strength of the positive association between FTP and preventive coping was strongest among the older participants, moderate among the middle-aged participants, and weakest among the younger participants. These results suggest that the association between FTP and preventive coping varies across the lifespan. © 2017 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Hour Glass Half-Full or Half-Empty? Future Time Perspective and Preoccupation with Negative Events Across the Life Span

According to socioemotional selectivity theory, older adults' emotional well-being stems from having limited future time perspective that motivates them to maximize well-being in the “here and now.” Presumably, then, older adults' time horizons are associated with emotional competencies that boost positive affect and dampen negative affect, but little research has addressed this. Using a US national adult life-span sample (N= 3,933, 18-93 yrs), we found that a two-factor model of future time perspective (focus on future opportunities; focus on limited time) fit the data better than a one-factor model. Through middle age, people perceived the life-span hourglass as half full—they focused more on future opportunities than limited time. Around age 60, the balance changed to increasingly perceiving the life-span hourglass as half empty—they focused less on future opportunities and more on limited time. This pattern held even after accounting for perceived health, self-reported decision-making ability, and retirement status. At all ages, women's time horizons focused more on future opportunities compared to men's, and men's focused more on limited time. Focusing on future opportunities was associated with reporting less preoccupation with negative events, whereas focusing on limited time was associated with reporting more preoccupation. Older adults reported less preoccupation with negative events and this association was stronger after controlling for their perceptions of limited time and fewer future opportunities, suggesting that other pathways may explain older adults' reports of their ability to disengage from negative events. Insights gained and questions raised by measuring future time perspective as two dimensions are discussed. PMID:27267222

Gellert, Paul; Ziegelmann, Jochen P; Lippke, Sonia; Schwarzer, Ralf

2012-04-01

Limitations in perceived lifetime can undermine long-term goal striving. Planning is supposed to translate intentions into health behaviors and to operate as a compensatory strategy to overcome goal striving deficits associated with a limited time perspective. Two longitudinal studies were conducted examining the compensatory role of planning: an online survey on fruit and vegetable consumption (N = 909; 16-78 years; follow-up at 4 months) and a questionnaire study on physical exercise in older adults (N = 289; 60-95 years, over a half-year period). Intentions, planning, and behavior were measured in a behavior-specific, future time perspective in a generic manner. Planning mediated between intentions and both health behaviors. Time perspective operated as a moderator, indicating that in individuals with a more limited time perspective, a stronger effect of planning on health behaviors emerged. Planning as a self-regulatory strategy may compensate for a limited time perspective.

Goell, Edgar

2012-02-15

During the last decade there have been several distinct activities and efforts with regards to future research in Egypt. Several institutions and capacities have been created. Although these capacities do not always meet high scientific standards, their results and studies offer important and well-grounded elements for future-oriented discussions and political decisions. Not least because of the Egypt revolt which started in January 2011 and the ongoing complex and conflicting societal struggles in Egypt the objective needs as well as the demand for systematic future thinking and future studies will very likely increase further. For that reason this report presents an overview about the context conditions, experiences and forms of future research in Egypt. The major challenges as well as the major issues are described. The main part is the description of the most important institutions, which are conducting future research, their projects and in addition two concrete projects, which try to practice Sustainable Development in different ways. Finally, several (self-)critical assessments and perspectives from selected experts of the future research community in Egypt will be presented.

Future perspectives of resin-based dental materials.

Jandt, Klaus D; Sigusch, Bernd W

2009-08-01

This concise review and outlook paper gives a view of selected potential future developments in the area of resin-based biomaterials with an emphasis on dental composites. A selection of key publications (1 book, 35 scientific original publications and 1 website source) covering the areas nanotechnology, antimicrobial materials, stimuli responsive materials, self-repairing materials and materials for tissue engineering with direct or indirect relations and/or implications to resin-based dental materials is critically reviewed and discussed. Connections between these fields and their potential for resin-based dental materials are highlighted and put in perspective. The need to improve shrinkage properties and wear resistance is obvious for dental composites, and a vast number of attempts have been made to accomplish these aims. Future resin-based materials may be further improved in this respect if, for example nanotechnology is applied. Dental composites may, however, reach a completely new quality by utilizing new trends from materials science, such as introducing nanostructures, antimicrobial properties, stimuli responsive capabilities, the ability to promote tissue regeneration or repair of dental tissues if the composites were able to repair themselves. This paper shows selected potential future developments in the area of resin-based dental materials, gives basic and industrial researchers in dental materials science, and dental practitioners a glance into the potential future of these materials, and should stimulate discussion about needs and future developments in the area.

D'Argembeau, Arnaud; Ortoleva, Claudia; Jumentier, Sabrina; Van der Linden, Martial

2010-09-01

This study sought to investigate the component processes underlying the ability to imagine future events, using an individual-differences approach. Participants completed several tasks assessing different aspects of future thinking (i.e., fluency, specificity, amount of episodic details, phenomenology) and were also assessed with tasks and questionnaires measuring various component processes that have been hypothesized to support future thinking (i.e., executive processes, visual-spatial processing, relational memory processing, self-consciousness, and time perspective). The main results showed that executive processes were correlated with various measures of future thinking, whereas visual-spatial processing abilities and time perspective were specifically related to the number of sensory descriptions reported when specific future events were imagined. Furthermore, individual differences in self-consciousness predicted the subjective feeling of experiencing the imagined future events. These results suggest that future thinking involves a collection of processes that are related to different facets of future-event representation.

Lifetime measurements in the picosecond range: Achievements and Perspectives

International Nuclear Information System (INIS)

Kruecken, Reiner

1999-01-01

This contribution will review the recoil distance method (RDM), its current range of applications as well as future perspectives for the measurement of lifetimes in the picosecond range of excited nuclear levels. Recent Doppler-shift lifetime experiments with large gamma-ray spectrometers have achieved a new level of precision and sensitivity, providing new insights into nuclear structure physics. High precision RDM measurements of near-yrast states in various mass regions have revealed dynamic shape effects beyond the framework of collective models and have also allowed to study the interaction between coexisting shapes. The measurement of lifetimes in superdeformed bands has shown that lifetimes can be measured for nuclear excitations, which are only populated with a few percent of the production cross-section of a nucleus. These experiments have also enabled us to study the mechanism of the decay-out of superdeformed bands. Another example for the need of precise lifetime measurements is the recent verifications of the concept of 'magnetic rotation' in nuclei by the experimental observation of the characteristic drop of B(M1) values as a function of angular momentum. These recent breakthroughs have also opened new perspectives for the use of the RDM technique for more exotic regions of nuclei and nuclear excitations. Here the measurement of lifetimes in neutron rich nuclei, which are not accessible with conventional nuclear reactions using stable beams and targets, is of special interest. Possible experimental approaches and simple estimates for the feasibility of such experiments will be presented. (author)

Negotiations between health and social goals over the lifespan: The role of future time perspective.

Science.gov (United States)

Li, Kin-Kit

2017-02-01

The interplay between health and social goals in relation to age and future time perspective was examined among 131 older and 131 younger adults via surveys and future time manipulations (limited, unchanged, and expansive). Being older was associated with weaker physical activity intentions and social activity intentions as mediated by a limited future time perspective. Physical activity intentions decreased in the limited condition and increased in the expansive condition, social activity intentions increased in all conditions, and preference toward health (over social) goals decreased in both the limited and expansive conditions. The results suggest that anticipated endings may become salient in all conditions and favor social goals, which are emotionally relevant.

Self-control mediates the relationship between time perspective and BMI.

Science.gov (United States)

Price, Menna; Higgs, Suzanne; Lee, Michelle

2017-01-01

Trait future time perspective measures the extent to which behaviour is dominated by a striving for future goals and rewards. Trait present time perspective measures orientation towards immediate pleasure. Previous research has explored the relationship between future and present time perspective and BMI with mixed findings. In addition, the psychological mechanism underlying this relationship is unclear. Self-control is a likely candidate, as it has been related to both BMI and time perspective, but the relationship between all of these concepts has not been examined in a single study. Therefore, the aim of this study was to examine if trait self-control mediates the relationship between time perspective (future and present) and BMI. Self-report time perspective (ZTPI), self-control (SCS) and height/weight data were collected using an online survey from a mixed student and community sample (N = 218) with wide ranging age (mean 29, SD 11, range 18-73 years) and BMI (mean 24, SD 4, range 15-43). The results of a structural equation model including both facets of time perspective suggested that the traits are related yet distinct measures that independently predict BMI through changes in self-control. Bootstrap mediation analysis showed that self-control mediated the relationship between both future time perspective (95% CI, -0.10 to -0.02) and present time perspective (95% CI, 0.03 to 0.17), and BMI in opposite directions. Participants with higher future time perspective scores (higher present time perspective scores) had higher (lower) self-control, which predicted lower (higher) BMI. These results are consistent with previous research suggesting an important role for time perspective in health outcomes. Self-control likely mediates the relationship between temporal perspectives and BMI, suggesting that time perspective may be a target for individualised interventions. Copyright © 2016 Elsevier Ltd.

Li, Tianyuan; Tsang, Vivian Hiu-Ling

2016-12-01

Individuals' understanding of wealth and power largely determines their use of resources. Moreover, the age range of wealth and power holders is increasing in modern societies. Thus, the current study examines how people of different ages understand wealth and power. As varying future time perspective is related to changes in prioritised life goals, it was tested as a potential mediator of the age differences. A total of 133 participants aged 18-78 years were asked 8 open-ended questions regarding their understanding of the possible use and desired use of wealth and power, after which they reported their future time perspective. Compared with possible use, the participants mentioned relatively more prosocial elements when they talked about their desired use of the resources, especially power. The older adults expressed more prosocial understanding in regard to the desired use of wealth and the possible use of power compared to their younger counterparts. The age differences were fully mediated by future time perspective. The results suggest that age is a critical factor that influences individuals' conceptualisation of wealth and power. Life-span developmental stage and future time perspective are important factors to consider for explaining individual differences in the exercise of wealth and power and for promoting their prosocial usage.

Time counts: future time perspective, goals, and social relationships.

Lang, Frieder R; Carstensen, Laura L

2002-03-01

On the basis of postulates derived from socioemotional selectivity theory, the authors explored the extent to which future time perspective (FTP) is related to social motivation, and to the composition and perceived quality of personal networks. Four hundred eighty German participants with ages ranging from 20 to 90 years took part in the study. In 2 card-sort tasks, participants indicated their partner preference and goal priority. Participants also completed questionnaires on personal networks and social satisfaction. Older people, as a group, perceived their future time as more limited than younger people. Individuals who perceived future time as being limited prioritized emotionally meaningful goals (e.g., generativity, emotion regulation), whereas individuals who perceived their futures as open-ended prioritized instrumental or knowledge-related goals. Priority of goal domains was found to be differently associated with the size, composition, and perceived quality of personal networks depending on FTP. Prioritizing emotion-regulatory goals was associated with greater social satisfaction and less perceived strain with others when participants perceived their future as limited. Findings underscore the importance of FTP in the self-regulation of social relationships and the subjective experience associated with them.

Future perspectives of transgender youth and their caregivers may be shaped by knowledge of discrimination and adverse mental health among transgender adults. Qualitative data from the Trans Youth Family Study were used to examine how transgender and gender nonconforming (TGN) youth and their caregivers imagine the youth's future. A community-based sample of 16 families (16 TGN youth, ages 7-18 years, and 29 caregivers) was recruited from two regions in the United States. Participants completed in-person qualitative interviews and surveys. Interview transcripts were analyzed using grounded theory methodology for coding procedures. Analyses yielded 104 higher order themes across 45 interviews, with eight prominent themes: comparing experiences with others, gender affirming hormones, gender affirming surgery, gender norms, questioning whether the youth is really transgender, expectations for romantic relationships, uncertainty about the future, and worries about physical and emotional safety. A conceptual model of future perspectives in TGN youth and caregivers is presented and clinical implications are discussed. PMID:28068129

Future energy perspectives: 1) The global energy consumption will continue to grow primarily in developing countries, their share of global energy consumption will grow from approx. 35% in 1990 to 60% in 2050. 2) Policy focus will be primarily on environmental concerns in the industrial countries and on energy for development and access to energy for the poor in developing countries. 3) With global climate concerns and the implementation of the Kyoto protocol, global environment issues will have increased prominence in energy sector priorities. 4) Fossil fuel resources are on a global level still abundant and prices are expected to be relatively low in the short to medium term. 5) Energy supply security has for geopolitical reasons become an increasing concern especially in the US and the EU. 6) Significant investments are required to ensure development of new clean energy technologies for introduction in the medium to long term. 7) Market reforms are being implemented in almost all regions of the world changing both the investment and policy regimes. 8) International studies (IPCC and WEC) have analysed several alternative energy scenarios Alternative policies and priorities can lead to a wide range of different energy futures. 9) WEC middle scenario B, from 1990 to 2050; predicts growth in GDP 3.5 times and primary energy consumption 2.2 times and CO{sub 2} 1.5 times. This scenario is expecting supply to be dominated by fossil fuel (80% in 1990 and still 65% in 2050), with high share of natural gas and nuclear with slow growth in renewable energy. 10) A more radical scenario (C1) is expecting renewable energy such as biomass, solar and wind to contribute 27% in 2050; declining oil and coal; increased use of natural gas and a minor contribution from nuclear. A development path like this require significant near-term investments in technology research and development. 11) The large increase in global energy demand in the next century will require large investments

We explore a new distinction between the future, prospective memory system being investigated in current neuroscience and the past, retrospective memory system, which was the original theoretical foundation of therapeutic hypnosis, classical psychoanalysis, and psychotherapy. We then generalize a current evolutionary theory of sleep and dreaming, which focuses on the future, prospective memory system, to conceptualize a new evolutionary perspective on therapeutic hypnosis and brief psychotherapy. The implication of current neuroscience research is that activity-dependent gene expression and brain plasticity are the psychobiological basis of adaptive behavior, consciousness, and creativity in everyday life as well as psychotherapy. We summarize a case illustrating how this evolutionary perspective can be used to quickly resolve problems with past obstructive procrastination in school to facilitate current and future academic success.

Four studies tested the prediction that positive affect (PA) would relate more strongly to meaning in life (MIL) as a function of perceived time limitations. In Study 1 (N = 360), adults completed measures of PA and MIL. As predicted, PA related more strongly to MIL for older, compared to younger, participants. In Studies 2 and 3, adults (N = 514) indicated their current position in their life span, and rated their MIL. PA, whether naturally occurring (Study 2) or induced (Study 3), was a stronger predictor of MIL for individuals who perceived themselves as having a limited amount of time left to live. Finally, in Study 4 (N = 98) students completed a measure of PA, MIL, and future time perspective (FTP). Results showed that PA was more strongly linked to MIL for those who believed they had fewer opportunities left to pursue their goals. Overall, these findings suggest that the experience of PA becomes increasingly associated with the experience of MIL as the perception of future time becomes limited. The contribution of age related processes to judgments of well-being are discussed.

The future role of photovoltaics: A learning curve versus portfolio perspective

International Nuclear Information System (INIS)

Albrecht, Johan

2007-01-01

The current cost disadvantage of photovoltaics (PV) risks to reduce its relevance in climate policy strategies. Depending on the used assumptions, electricity from PV can become competitive between 2015 and 2040. Cost competitiveness is, however, a conditional criterion and as an alternative to the learning curve perspective, the future role of PV in electricity production is assessed from a portfolio theory or Capital Asset Pricing Model perspective. In this analysis, the focus is on the input price risks. Fossil fuel price volatility can strongly reduce the financial return of conventional generating technologies. From a welfare perspective, energy planners should try to minimise this risk by adding risk-neutral or no-risk technologies to their portfolio. With an analysis for the year 2025, we illustrate how the addition of renewable capacity to an existing portfolio can lower total portfolio risk without a significant reduction of profitability. PV then emerges as an attractive technology, especially once the best locations for wind energy are already developed

A perspective on the future public health practitioner.

In the centuries following the Enlightenment, scientific and technological developments gave 'modern people' an unprecedented ability to understand, predict and control the natural world. This has brought health and social benefits unimaginable to our ancestors and sets us apart from all previous generations. Yet there is a wide-ranging body of evidence that suggests that modernity is now in decline, largely because its methods and mindset are increasingly recognized as unsustainable. Problems are manifest in the emergence of new public health epidemics such as obesity and addictive behaviours, the loss of well-being and increase in anxiety and depression in affluent society, and the persistence of ever-widening health and social inequalities at national and global levels. Still larger problems now confront us, such as climate change, peak oil and the loss of biodiversity, all of which are linked to the 'modern' way of life. We are potentially faced with the collapse of certain aspects of modern society: we are certainly faced with the prospect of inevitable change. While the broad public health community has an important role to play in developing workable solutions to such daunting problems, we argue that some profound changes will be needed in order for us to cope successfully. No blueprints for dealing with change exist, which means that we will need to learn our way into the future. In this paper we take a perspective on the role and nature of the future practitioner in public health and health promotion. We argue that future practitioners will need to develop new ways of thinking, being and doing; new perspectives and new forms of understanding the world. We believe our discipline - and people generally - to be capable of such development, as insights from multiple sources tell us that human nature is malleable, not fixed. We use this analysis to trace, as examples, the imagined lives of five women living in different eras over the course of history in a

Future time perspective and promotion focus as determinants of intraindividual change in work motivation.

In the near future, workforces will increasingly consist of older workers. At the same time, research has demonstrated that work-related growth motives decrease with age. Although this finding is consistent with life span theories, such as the selection optimization and compensation (SOC) model, we know relatively little about the process variables that bring about this change in work motivation. Therefore, we use a 4-wave study design to examine the mediating role of future time perspective and promotion focus in the negative association between age and work-related growth motives. Consistent with the SOC model, we found that future time perspective was negatively associated with age, which, in turn, was associated with lower promotion focus, lower work-related growth motive strength, and lower motivation to continue working. These findings have important theoretical implications for the literature on aging and work motivation, and practical implications for how to motivate older workers.

Choices for A Brighter Future: Perspectives on Renewable Energy

Energy Technology Data Exchange (ETDEWEB)

NREL

1999-09-30

The report discusses the perspectives on the evolving U.S. electricity future, the renewable electric technology portfolio, the regional outlook, and the opportunities to move forward. Renewables are at a critical juncture as the domestic electricity marketplace moves toward an era of increased choice and greater diversity. The cost and performance of these technologies have improved dramatically over the past decade, yet their market penetration has stalled as the power industry grapples with the implications of the emerging competitive marketplace. Renewable energy technologies already contribute to the global energy mix and are ready to make an even greater contribution in the future. However, the renewables industry faces critical market uncertainties, both domestically and internationally, as policy commitments to renewables at both the federal and state levels are being reshaped to match the emerging competitive marketplace. The energy decisions that we make, or fail to make, today will have long-lasting implications. We can act now to ensure that renewable energy will play a major role in meeting the challenges of the evolving energy future. We have the power to choose.

Background. Previous studies have established a link between how people relate to their past, present, and future (i.e., time perspective) and subjective well-being (i.e., life satisfaction, positive and negative affect). Time perspective comprises five dimensions: Past Positive, Past Negative, Present Hedonistic, Present Fatalistic, and Future. Life satisfaction can also be evaluated in relation to different time frames. Moreover, approach related positive affect is associated to a different concept of well-being labeled psychological well-being. In the present study we extend previous findings by investigating the effect of time perspective on the time frame of evaluations of life satisfaction (past, present, future) and by investigating the relationship between time perspective and psychological well-being. Method. Questionnaires on time perspective (Zimbardo’s Time Perspective Inventory), temporal life satisfaction (Temporal Satisfaction with Life Scale), affect (Positive Affect and Negative Affect Schedule), and psychological well-being (Scales of Psychological Well-Being—short version) were answered by 453 individuals. Two different structural equation models were tested, one of the relationship between time perspective and temporal life satisfaction, and the other of the relationship between time perspective, affect and psychological well-being. Results. Time perspective affected life satisfaction depending on the time scale on which it was evaluated—memory of a negative past influenced life satisfaction in all time frames, and a positive view of the past influenced both past and future life satisfaction. Moreover, less rumination about past negative events (i.e., low score on Past Negative), the tendency to take risks in the present to achieve happy feelings and/or avoid boredom (i.e., high scores on Present Hedonistic), and a less hopeless and pessimistic view about the present (low scores on Present Fatalistic) were associated with higher levels of

The High Flux Isotope Reactor (HFIR) is a vital national and international resource for neutron science research, production of radioisotopes, and materials irradiation. While HFIR is expected to continue operation for the foreseeable future, interest is growing in understanding future research reactors features, needs, and requirements. To clarify, discuss, and compile these needs from the perspective of Oak Ridge National Laboratory (ORNL) research and development (R&D) missions, a workshop, titled “Needs and Requirements for Future Research Reactors”, was held at ORNL on May 12, 2015. The workshop engaged ORNL staff that is directly involved in research using HFIR to collect valuable input on the reactor’s current and future missions. The workshop provided an interactive forum for a fruitful exchange of opinions, and included a mix of short presentations and open discussions. ORNL staff members made 15 technical presentations based on their experience and areas of expertise, and discussed those capabilities of the HFIR and future research reactors that are essential for their current and future R&D needs. The workshop was attended by approximately 60 participants from three ORNL directorates. The agenda is included in Appendix A. This document summarizes the feedback provided by workshop contributors and participants. It also includes information and insights addressing key points that originated from the dialogue started at the workshop. A general overview is provided on the design features and capabilities of high performance research reactors currently in use or under construction worldwide. Recent and ongoing design efforts in the US and internationally are briefly summarized, followed by conclusions and recommendations.

Recently the psychological effects of space flight have gained in attention. In uncovering the psychological challenges that individuals and teams can face, we need research options that integrate psychosocial aspects with behavioral, performance, technical and environmental issues. Future perspectives in Space Psychology and Human Spaceflight are reviewed in this paper. The topics covered include psychosocial and neurobehavioural aspects, neurocognitive testing tools, decision making, autonomy and delayed communications, well being, mental health, situational awareness, and methodology. Authors were members of a European Space Agency (ESA) Research Topical Team on Psychosocial and Behavioral Aspects of Human Spaceflight. They discuss the different topics under a common perspective of a theoretical and practical framework, showing interactions, relationships and possible solutions for the different aspects and variables in play. Recommendations for every topic are offered and summarized for future research in the field. The different proposed research ideas can be accomplished using analogs and simulation experiments, short- and long-duration bed rest, and in-flight microgravity studies. These topics are especially important for future Moon and Mars mission design and training.

Future potential country doctor: the perspectives of German GPs.

Science.gov (United States)

Natanzon, Iris; Szecsenyi, Joachim; Ose, Dominik; Joos, Stefanie

2010-01-01

There is a shortage of general practitioners (GPs) in many countries, especially in rural areas. There are several reasons for this shortage. Over the last decade, fewer medical students in Germany have decided to work in patient care, even fewer in general practice and fewer still in general practice in rural areas. The aim of this study was to explore the 'pros and cons' of GPs' work in rural areas and to identify from GPs' perspective possible measures for counteracting future GP shortages. Within a qualitative approach, 16 semi-structured interviews were conducted with GPs. Data analysis was carried out using qualitative content analysis. The results were categorized into three main inductively-derived categories: personal, professional and regional/structural level. A higher level of self-confidence and a higher 'feel-good' factor due to GPs originating from rural areas were positive aspects at the personal level. Regarding the professional level, a low level of competition and varied work made a GP's profession attractive in rural areas. Negative aspects were mostly apparent at the regional/structural level, such a low earnings and few leisure facilities. Measures to counter the lack of GPs in rural areas were explored on all three levels: on the personal level, more optimism and resulting satisfaction on the part of doctors in rural areas could be improved by enhancing the benefits of being a doctor in a rural area. Regarding the professional level, more group practices are required to make working as a GP in a rural area more attractive. At a regional/structural level, young physicians who originate from rural areas should be recruited to work in rural areas. Financial incentives are regarded as not sufficient to attract enough young physicians to open practices in rural areas. Future action will be required at the personal, professional and regional/structural levels. The origin of medical students (urban or rural) should be considered a relevant

2012-10-01

Increased utilization of medical imaging in the early part of the last decade has resulted in numerous efforts to reduce associated spending. Recent initiatives have focused on managing utilization with radiology benefits managers and real-time order entry decision support systems. Although these approaches might seem mutually exclusive and their application to radiology appears unique, the historical convergence and broad acceptance of both programs within the pharmacy sector may offer parallels for their potential future in medical imaging. In this second installment of a two-part series, anticipated trends in radiology utilization management are reviewed. Perspectives on current and future potential roles of radiologists in such initiatives are discussed, particularly in light of emerging physician payment models.

Perception of effort in Exercise Science: Definition, measurement and perspectives.

Science.gov (United States)

Pageaux, Benjamin

2016-11-01

Perception of effort, also known as perceived exertion or sense of effort, can be described as a cognitive feeling of work associated with voluntary actions. The aim of the present review is to provide an overview of what is perception of effort in Exercise Science. Due to the addition of sensations other than effort in its definition, the neurophysiology of perceived exertion remains poorly understood. As humans have the ability to dissociate effort from other sensations related to physical exercise, the need to use a narrower definition is emphasised. Consequently, a definition and some brief guidelines for its measurement are provided. Finally, an overview of the models present in the literature aiming to explain its neurophysiology, and some perspectives for future research are offered.

Future perspectives of nutrigenomics foods: benefits vs. risks.

Science.gov (United States)

Ghosh, Dilip

2009-02-01

Nutrigenomics, defined as the application of high-throughput genomics tools in nutrition research is now past its incubation phase. The poorly understood associations of diet and disease prevention in particular will likely be the single most important catalyst to its accelerated and continued growth. Whether the goal of matching foods to individual genotypes to improve the health of those individuals can be attained, and personalised nutrigenomic foods enter the world's food markets, depends on numerous hurdles being overcome: some scientific in nature, some' technical and others related to consumer, market or ethical issues. Public adoption of new technologies is an important determinant for their success. Many of the drivers behind the trend in personalisation of food are now known, particularly ethical, legal, and social issues (ELSI) are the major drivers. Future development in the field of nutrigenomics undoubtedly will place its seemingly huge potential in better perspective. From the scientific responsibility point of view, one hopes that the new perspectives to be gained and progress to be made in this field will be so managed as to take the public at large on board, if we are to avoid another nutrition education disaster of the genetically modified organism type and dimension.

The aim of this report is to give basic notions on electromagnetic hadron form factors (FFs), as they are understood at the present time, to summarize and analyze the present experimental results and available theoretical models and to open a view on future perspectives. FFs are fundamental quantities, which describe the internal, dynamical structure of hadrons. Although the theoretical formalism was settled in the middle of last century, as well as the first experiments in electron–proton elastic scattering for which R. Hofstadter got the Nobel prize in 1961, a renewed activity is due to recent, surprising results and to the opening of new experimental possibilities. An elegant formalism was built on the assumption of a hadron electromagnetic interaction based on the exchange of a virtual photon of four-momentum q{sup 2}. In this case FFs are analytic functions of only one variable, q{sup 2}, and the electromagnetic vertex γ{sup ∗}hh (h is any hadron) is defined by two structure functions, which, in turn, are expressed in terms of (2S+1) FFs, S being the hadron spin, assuming parity and time-invariance. Our aim is to anticipate the potentiality contained in the future data, combined with the present knowledge, to point out the relevant observables and the most significative measurements, and to give predictions to be compared to the data when they will be available.

An elegant formalism was built on the assumption of a hadron electromagnetic interaction based on the exchange of a virtual photon of four-momentum q 2 . In this case FFs are analytic functions of only one variable, q 2 , and the electromagnetic vertex γ ∗ hh (h is any hadron) is defined by two structure functions, which, in turn, are expressed in terms of (2S+1) FFs, S being the hadron spin, assuming parity and time-invariance. Our aim is to anticipate the potentiality contained in the future data, combined with the present knowledge, to point out the relevant observables and the most significative measurements, and to give predictions to be compared to the data when they will be available

The Physics Perspectives at the Future Accelerator Facility FAIR

CERN Document Server

Stroth, J

2004-01-01

The physics perspective of the approved future international accelerator Facility for Anti-proton and Ion Research (FAIR) near Darmstadt, Germany will be outlined. The physics programme will comprise many body aspects of matter ranging from macroscopic system like highly correlated plasmas down to the properties of baryons and nuclear matter at high baryon densities. Through fragmentation of intense ion beams investigations with beams of short-lived radioactive nuclei far from stability will be possible. The addressed physics questions concern nuclear structure at the drip-lines, areas of astrophysics and nucleo-synthesis in supernovae and other stellar processes, as well as tests of fundamental symmetry. The structure of baryons and their limits of their existence is the interest of the two large experimental set-ups PANDA and CBM. Finally QED will be studied in extremely strong field effects and also the interaction of ions with matter. The future facility will feature a double-ring synchrotron SIS100/300 a...

Ophthalmology's future in the next decade: a historical and comparative perspective.

Science.gov (United States)

Day, S H

1999-01-01

To gain a historical and comparative perspective about the future of ophthalmology within the profession of medicine. A literature search is made of disciplines other than medicine (history, sociology, philosophy, economics, and ethics) in order to assess factors responsible for survival and healthiness of a profession. The "learned" professions (medicine, law, and theology) are assessed. Other "professional" careers valued by society (sports and classical music) are reviewed. From the perspective of other disciplines, the future of ophthalmology is seen as vulnerable and fragile. Survival of professions, be they classically or economically defined, is linked to societal needs, a profession's unique commitment and ability to provide services to society, and the profession's maintenance of knowledge as well as skill-based services. Historical evidence has shown erosion of a profession's power consequent to capitalist influences, government influences, access of skills by less trained individuals, and elitist posturing by a profession. Comparative evidence has shown societal acceptance of an escalation of salaries for designated superstars, increasing roles and influence of managerial personnel, and trivialization of values other than economic ones. Attention to historical and comparative trends by individual ophthalmologists as well as associations representing ophthalmologists is mandatory if ophthalmology as we know it is to survive within the profession of medicine.

2016-01-01

The High Flux Isotope Reactor (HFIR) is a vital national and international resource for neutron science research, production of radioisotopes, and materials irradiation. While HFIR is expected to continue operation for the foreseeable future, interest is growing in understanding future research reactors features, needs, and requirements. To clarify, discuss, and compile these needs from the perspective of Oak Ridge National Laboratory (ORNL) research and development (R&D) missions, a workshop, titled ''Needs and Requirements for Future Research Reactors'', was held at ORNL on May 12, 2015. The workshop engaged ORNL staff that is directly involved in research using HFIR to collect valuable input on the reactor's current and future missions. The workshop provided an interactive forum for a fruitful exchange of opinions, and included a mix of short presentations and open discussions. ORNL staff members made 15 technical presentations based on their experience and areas of expertise, and discussed those capabilities of the HFIR and future research reactors that are essential for their current and future R&D needs. The workshop was attended by approximately 60 participants from three ORNL directorates. The agenda is included in Appendix A. This document summarizes the feedback provided by workshop contributors and participants. It also includes information and insights addressing key points that originated from the dialogue started at the workshop. A general overview is provided on the design features and capabilities of high performance research reactors currently in use or under construction worldwide. Recent and ongoing design efforts in the US and internationally are briefly summarized, followed by conclusions and recommendations.

Future time perspective (FTP) modulates individuals' temporal orientation in selecting their motivations and goals, which widely influences their cognitions and behaviors. However, it remains unclear how FTP exactly affects intertemporal choice. To clarify the effect of FTP on intertemporal choice, 90 college students ( M age = 21.70, SD = 1.23) were randomly assigned to the limited FTP condition (16 males, 29 females) and the open-ended FTP condition (17 males, 28 females). In the limited FTP condition, participants were instructed to imagine their states of being 70 years old, whereas in the open-ended FTP condition, they were instructed to describe their current states. All participants then completed a series of intertemporal choice tasks, in which they chose from gain- and loss-related choices occurring at various time points. Results showed that the participants who received the future-imagining manipulation had more limited FTP compared with those who did not receive the manipulation, which confirmed the validity of the FTP manipulation. A 2 (FTP: limited vs. open-ended) × 2 (type of choice: gain vs. loss) repeated measures ANOVA on discount rate revealed a significant interaction between these two factors. The participants in the limited FTP condition had higher discount rates on gain-related choices but showed no difference on loss-related choices compared with the participants under the open-ended FTP condition. The results suggest that limited FTP could lower individuals' future orientation (i.e., willingness to delay an outcome) on gain-related, but not on loss-related, intertemporal decision-making.

Global perspectives on future nuclear energy utilisation

International Nuclear Information System (INIS)

Watts, G.L.

1998-01-01

This paper is presented as an overview of the nuclear sector from a global perspective. The aim is to show that nuclear power does have a future but that this will only be fully realised when the industry is able to demonstrate that it is part of the solution to the world's energy and environmental difficulties rather than part of the problem. The paper looks at the projected world energy demand as the population increases and countries develop, showing that nuclear power is required to meet this demand. In presenting nuclear power as a solution, the paper addresses the challenges facing us such as public confidence, environmental opposition, political issues and finance. It addresses the debate over reprocessing and direct disposal of irradiated nuclear fuel and looks at the competition from other fuels. The paper suggests how the industry might approach these issues such that nuclear power is indeed regarded globally as a solution to some of the worlds most pressing problems. (author)

2018-01-01

As robotics are becoming more integrated into the medical field, robotic training is becoming more crucial in order to overcome the lack of experienced robotic surgeons. However, there are several obstacles facing the development of robotic training programs like the high cost of training and the increased operative time during the initial period of the learning curve, which, in turn increase the operative cost. Robotic-assisted laparoscopic prostatectomy is the most commonly performed robotic surgery. Moreover, robotic surgery is becoming more popular among urologic oncologists and pediatric urologists. The need for a standardized and validated robotic training curriculum was growing along with the increased number of urologic centers and institutes adopting the robotic technology. Robotic training includes proctorship, mentorship or fellowship, telementoring, simulators and video training. In this chapter, we are going to discuss the different training methods, how to evaluate robotic skills, the available robotic training curriculum, and the future perspectives.

2015-10-01

Full Text Available Purpose – The purpose of this paper is to put forward the argument that New Zealand�s tourism industry generally fails to acknowledge the importance of the access market. Despite anecdotal evidence of the market's value and strong legislation, New Zealand�s access market arguably remains underserviced and misunderstood. The current research sought to explore social and business rationales to support a future for accessible tourism in New Zealand, from the perspectives of its key stakeholders. It sought to uncover contemporary issues in the tourism industry, to examine the capacity and context for which issues can be addressed and overcome, to achieve a future for accessible tourism in New Zealand. Design/methodology/approach – Under the interpretive paradigm, original, exploratory research was conducted. Semi-structured interviews were carried out with ten key New Zealand tourism industry stakeholders who agreed to participate in the research. Qualitative data were thematically analysed. The following five key themes inductively emerged from the data: "Accessibility as a human right: Developing a culture of accessibility"; "Accessible tourism: Good for business?"; "Bottom-up, market-led approach"; "Leadership from the top: Moving from apathy to action"; and "Meeting somewhere in the middle". The five themes correspond to themes evidenced in the wider literature and present propositions for the future development of accessible tourism in New Zealand. Findings – Findings revealed stakeholder opinions of an industry exemplifying minimal awareness and consideration for accessibility. Accessibility was perceived to be an issue of social change, requiring the achievement of a cultural shift where accessibility is envisioned as a cultural norm necessary for the future. Whilst top-down leadership and support were deemed pertinent, ownership and accountability were seen to be crucial at the lower, operational levels of the industry. A "meeting

Perspectives on Emerging/Novel Computing Paradigms and Future Aerospace Workforce Environments

Science.gov (United States)

Noor, Ahmed K.

2003-01-01

The accelerating pace of the computing technology development shows no signs of abating. Computing power reaching 100 Tflop/s is likely to be reached by 2004 and Pflop/s (10(exp 15) Flop/s) by 2007. The fundamental physical limits of computation, including information storage limits, communication limits and computation rate limits will likely be reached by the middle of the present millennium. To overcome these limits, novel technologies and new computing paradigms will be developed. An attempt is made in this overview to put the diverse activities related to new computing-paradigms in perspective and to set the stage for the succeeding presentations. The presentation is divided into five parts. In the first part, a brief historical account is given of development of computer and networking technologies. The second part provides brief overviews of the three emerging computing paradigms grid, ubiquitous and autonomic computing. The third part lists future computing alternatives and the characteristics of future computing environment. The fourth part describes future aerospace workforce research, learning and design environments. The fifth part lists the objectives of the workshop and some of the sources of information on future computing paradigms.

With its diverse, living marine resources and rapidly growing educational and research infrastructure, the Sultanate of Oman is well-positioned to take advantage of the commercial opportunities presented by marine biotechnology. In recognition of potential development, an international symposium, Marine Biotechnology-Emerging Opportunities and Future Perspectives, was held in Muscat, November 12-13, 2013. Three keynote addresses were given, 23 oral presentations made, and a poster exhibition held. The final session reviewed national and regional issues, and the delegates agreed informally on a number of future actions. The potential for future development of marine biotechnology was recognized by all delegates, and following the symposium, they were surveyed for their views on how best to sustain and develop new activities. One hundred percent of respondents found the meeting useful and would support future symposia in the region. Fifty-one percent of Omani respondents recognized major organizational challenges and obstacles to the development of marine biotechnology compared with 23 % of overseas respondents. The need for greater collaboration between research institutions within the GCC region was recognized by 98 % of all respondents. The presentations and survey outcomes are reviewed in this paper.

Problematic Internet use, maladaptive future time perspective and school context.

Spain is among the European countries with the highest prevalence of adolescents at risk of Internet addiction, a problem that could be linked to youth unemployment and leaving education early. This research evaluated the role of three variables relative to school context on Problematic Internet Use (PIU) and on the relationship between PIU and Maladaptive Future Time Perspective (MFTP, defined as an excessive focus on the present and a fatalistic attitude towards the future, a variable that had not previously been studied in terms of its relationship to adolescents' PIU). The study was carried out with 1288 adolescents, aged 12 to 16 years old, enrolled at 31 secondary schools in Madrid, Spain. As expected, we found that MFTP and hostile treatment by teachers were associated with an increase in PIU, whereas school appreciation was associated with a decrease in PIU. In addition, hostile treatment by teachers had a moderate effect on the MFTP-PIU relationship. In order to prevent PIU it is important to foster confidence in adolescents in their own potential to build the future from the present through positive interaction with teachers, stimulating an appreciation of school within these digital natives' peer group culture.

Future time perspective (FTP) may predict individual attitudes and behaviors. However, FTP research includes different FTP conceptualizations and outcomes which hinder generalizing its findings. To solve the inconsistencies in FTP research and generalize the magnitude of FTP as a driver of motivation and behavior, we conducted the first systematical synthesis of FTP relationships in three crucial life domains. Our meta-analyses of FTP studies in education (k = 28), work (k = 17), and health (k = 32) involved N = 31,558 participants, and used a conceptual model for grouping FTP constructs. To address different outcome types, we applied the Theory of Planned Behavior when coding the studies. FTP relationships with outcomes were small-to-medium, were generalizable across domains, and were strongest when the FTP construct included a mixture of cognition, behavioral intention, and affect and, in education, when the FTP measure was domain specific rather than general. There were cross-cultural differences in FTP-outcome relationships. The strength of the FTP-outcome types relationship varied for attitudes, perceived behavioral control, behavioral intention, and behaviors. The lowest effect sizes were found for FTP predicting actual behaviors in education, work, and health and between FTP and health attitudes. Theoretical implications of the findings and future research directions are discussed.

Can the Stark-Einstein law resolve the measurement problem from an animate perspective?

Science.gov (United States)

Thaheld, Fred H

2015-09-01

Analysis of the Stark-Einstein law as it applies to the retinal molecule, which is part of the rhodopsin molecule within the rod cells of the retina, reveals that it may provide the solution to the measurement problem from an animate perspective. That it represents a natural boundary where the Schrödinger equation or wave function automatically goes from linear to nonlinear while remaining in a deterministic state. It will be possible in the near future to subject this theory to empirical tests as has been previously proposed. This analysis provides a contrast to the many decades well studied and debated inanimate measurement problem and would represent an addition to the Stark-Einstein law involving information carried by the photon.

Unraveling the plant microbiome: looking back and future perspectives

Directory of Open Access Journals (Sweden)

Gabriele eBerg

2014-06-01

Full Text Available Most eukaryotes develop close interactions with microorganisms that are essential for their performance and survival. Thus, eukaryotes and prokaryotes in nature can be considered as meta-organisms or holobionts. Consequently, microorganisms that colonize different plant compartments contain the plant’s second genome. In this respect, many studies in the last decades have shown that plant-microbe interactions are not only crucial in understanding plant growth and health, but also for sustainable crop production in a changing world. This mini-review acting as editorial presents retrospectives and future perspectives for plant microbiome studies as well as information gaps in this emerging research field. In addition, the contribution of this research topic to the solution of various issues is discussed.

1999-06-01

Self-handicapping motivation refers to the likelihood a person will project personal ambition into the future, make a pessimistic judgement, and then mobilise effort in the present to avoid an anticipated negative outcome. It should, therefore, be a correlate of future time perspective. This study showed for a sample of 120 first-year students that, whilst future time perspective did strongly predict scores on a measure of self-handicapping motivation, neither variable was a useful predictor of outcome.

Barthelmess, Erin K.; Naz, Rajesh K.

2015-01-01

Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed. PMID:24389146

Time perspective describes how individuals conceptualize and value future events, and may be related to health behaviours. Research to date has focused on addictive behaviours, used a variety of different measures of time perspective, and not explored the role of personality. This work aimed to: explore the relationships between: five previously used measures of time perspective; time perspective and the broad domains of the five-factor model of personality; and time perspective and smoking, body mass, and physical activity after controlling for socio-demographics and personality. Cross-sectional self-report data were collected using a web based survey. Participants (N=423) were recruited via local community internet message boards in US urban areas. The survey collected information on: delay discount rate, the Consideration of Future Consequences Scale (CFCS), the future scale of the Zimbardo Time Perspective Inventory (ZTPI), subjective probability of living to age 75, and time period for financial planning, the five-factor personality inventory, smoking, body mass index (BMI), and physical activity. After controlling for socio-demographics, most markers of time perspective were significantly correlated with each other, but the strength of correlations was rarely strong. Conscientiousness, Neuroticism, Agreeableness, and Openness were associated with some markers of time perspective. After controlling for socio-demographic and personality domains, only CFCS score was associated with smoking status and BMI. There is some overlap between previously used markers of time perspective and the five-factor personality domains but this is neither strong nor consistent. Smoking and BMI, but not physical activity, are associated with CFCS, but not other measures of time perspective.

Prospects for future measurements of Deeply Virtual Compton Scattering are studied using different simple models for parameterizations of generalized parton distributions (GPDs). Measurements of the lepton charge and lepton beam helicity asymmetry will yield important input for theoretical models towards the future extraction of GPDs. The kinematics of the HERMES experiment, complemented with a recoil detector, was adopted to arrive at realistic projected statistical uncertainties. (orig.)

Guthrie, Lori C; Butler, Stephen C; Lessl, Kristen; Ochi, Onyinyechukwu; Ward, Michael M

2014-01-01

Time perspective, a psychological construct denoting subjective orientation to either present or future concerns, has been inconsistently associated with healthy behaviors in adults. We hypothesized that associations would be stronger in young adults, who are first developing independent attitudes, than in older adults. Cross-sectional survey. The study was conducted in three cities in the Mid-Atlantic region. Subjects were 790 patrons of barber and beauty shops. Measures used were the Zimbardo Time Perspective Inventory future, present-fatalistic, and present-hedonistic subscales and current smoking, days per week of recreational exercise, and height and weight, by self-report. We tested if associations between time perspective and exercise, obesity, and current smoking differed by age group (18-24 years, 25-34 years, and 35 years and older) using analysis of variance and logistic regression. Higher future time perspective scores, indicating greater focus on future events, was associated with more frequent exercise, whereas higher present-fatalistic time perspective scores, indicating more hopelessness, was associated with less frequent exercise in 18- to 24-year-olds, but not in older individuals. Lower future time perspective scores, and higher present-hedonistic time perspective scores, indicating interest in pleasure-seeking, were also associated with obesity only in 18- to 24-year-olds. Current smoking was not related to time perspective in any age group. Time perspective has age-specific associations with exercise and obesity, suggesting stages when time perspective may influence health behavior decision making.

Brothers, Allyson; Gabrian, Martina; Wahl, Hans-Werner; Diehl, Manfred

2016-09-01

This study examined how 2 distinct facets of perceived personal lifetime-future time perspective (FTP) and awareness of age-related change (AARC)-are associated with another, and how they may interact to predict psychological well-being. To better understand associations among subjective perceptions of lifetime, aging, and well-being, we tested a series of models to investigate questions of directionality, indirect effects, and conditional processes among FTP, AARC-Gains, AARC-Losses, and psychological well-being. In all models, we tested for differences between middle-aged and older adults, and between adults from the United States and Germany. Analyses were conducted within a structural equation modeling framework on a cross-national, 2.5-year longitudinal sample of 537 community-residing adults (age 40-98 years). Awareness of age-related losses (AARC-Losses) at Time 1 predicted FTP at Time 2, but FTP did not predict AARC-Gains or AARC-Losses. Furthermore, future time perspective mediated the association between AARC-Losses and well-being. Moderation analyses revealed a buffering effect of awareness of age-related gains (AARC-Gains) in which perceptions of more age-related gains diminished the negative effect of a limited future time perspective on well-being. Effects were robust across age groups and countries. Taken together, these findings suggest that perceived age-related loss experiences may sensitize individuals to perceive a more limited future lifetime which may then lead to lower psychological well-being. In contrast, perceived age-related gains may function as a resource to preserve psychological well-being, in particular when time is perceived as running out.

Future of Atmospheric Neutrino Measurements

International Nuclear Information System (INIS)

Choubey, Sandhya

2013-01-01

Discovery of large θ 13 has opened up the possibility of determining the neutrino mass hierarchy and θ 23 octant through earth matter effects. The atmospheric neutrinos pick up large earth matter effects both in the ν e and ν μ channels, which if observed could lead to the determination of the mass hierarchy and θ 23 octant using this class of experiments in the near future. In this talk I review the status and prospects of future atmospheric neutrino measurements in determining the mass hierarchy and octant of θ 23

Inequality measures for wealth distribution: Population vs individuals perspective

Science.gov (United States)

Pascoal, R.; Rocha, H.

2018-02-01

Economic inequality is, nowadays, frequently perceived as following a growing trend with impact on political and religious agendas. However, there is a wide range of inequality measures, each of which pointing to a possibly different degree of inequality. Furthermore, regardless of the measure used, it only acknowledges the momentary population inequality, failing to capture the individuals evolution over time. In this paper, several inequality measures were analyzed in order to compare the typical single time instant degree of wealth inequality (population perspective) to the one obtained from the individuals' wealth mean over several time instants (individuals perspective). The proposed generalization of a simple addictive model, for limited time average of individual's wealth, allows us to verify that the typically used inequality measures for a given snapshot instant of the population significantly overestimate the individuals' wealth inequality over time. Moreover, that is more extreme for the ratios than for the indices analyzed.

Background. Previous studies have established a link between how people relate to their past, present, and future (i.e., time perspective) and subjective well-being (i.e., life satisfaction, positive and negative affect). Time perspective comprises five dimensions: Past Positive, Past Negative, Present Hedonistic, Present Fatalistic, and Future. Life satisfaction can also be evaluated in relation to different time frames. Moreover, approach related positive affect is associated to a different...

A critical evaluation of the validity of episodic future thinking: A clinical neuropsychology perspective.

Science.gov (United States)

Ward, Amanda M

2016-11-01

Episodic future thinking is defined as the ability to mentally simulate a future event. Although episodic future thinking has been studied extensively in neuroscience, this construct has not been explored in depth from the perspective of clinical neuropsychology. The aim of this critical narrative review is to assess the validity and clinical implications of episodic future thinking. A systematic review of episodic future thinking literature was conducted. PubMed and PsycInfo were searched through July 2015 for review and empirical articles with the following search terms: "episodic future thinking," "future mental simulation," "imagining the future," "imagining new experiences," "future mental time travel," "future autobiographical experience," and "prospection." The review discusses evidence that episodic future thinking is important for adaptive functioning, which has implications for neurological populations. To determine the validity of episodic future thinking, the construct is evaluated with respect to related constructs, such as imagination, episodic memory, autobiographical memory, prospective memory, narrative construction, and working memory. Although it has been minimally investigated, there is evidence of convergent and discriminant validity for episodic future thinking. Research has not addressed the incremental validity of episodic future thinking. Practical considerations of episodic future thinking tasks and related constructs in a clinical neuropsychological setting are considered. The utility of episodic future thinking is currently unknown due to the lack of research investigating the validity of episodic future thinking. Future work is discussed, which could determine whether episodic future thinking is an important missing piece in standard clinical neuropsychological assessment.

Li, Zhaoqin; Xu, Dandan; Guo, Xulin

2014-11-07

Maintaining a healthy ecosystem is essential for maximizing sustainable ecological services of the best quality to human beings. Ecological and conservation research has provided a strong scientific background on identifying ecological health indicators and correspondingly making effective conservation plans. At the same time, ecologists have asserted a strong need for spatially explicit and temporally effective ecosystem health assessments based on remote sensing data. Currently, remote sensing of ecosystem health is only based on one ecosystem attribute: vigor, organization, or resilience. However, an effective ecosystem health assessment should be a comprehensive and dynamic measurement of the three attributes. This paper reviews opportunities of remote sensing, including optical, radar, and LiDAR, for directly estimating indicators of the three ecosystem attributes, discusses the main challenges to develop a remote sensing-based spatially-explicit comprehensive ecosystem health system, and provides some future perspectives. The main challenges to develop a remote sensing-based spatially-explicit comprehensive ecosystem health system are: (1) scale issue; (2) transportability issue; (3) data availability; and (4) uncertainties in health indicators estimated from remote sensing data. However, the Radarsat-2 constellation, upcoming new optical sensors on Worldview-3 and Sentinel-2 satellites, and improved technologies for the acquisition and processing of hyperspectral, multi-angle optical, radar, and LiDAR data and multi-sensoral data fusion may partly address the current challenges.

Veterinary education in Africa: current and future perspectives.

Science.gov (United States)

Swan, G E; Kriek, N P J

2009-03-01

Veterinary education commenced in South Africa in 1920 at the Onderstepoort Veterinary Institute in South Africa in association with the Transvaal University College, now the University of Pretoria. Sir Arnold Theiler, Director of Veterinary Research and Education, was the first Dean. Today there are 46 veterinary training institutions in Africa of which 21 are in sub-Saharan Africa. Veterinary services are indispensable to the sustained health and wellbeing of animals and humans, and agricultural economies of countries worldwide. Veterinary education, postgraduate training, and research, and adequate numbers of veterinarians, are essential to satisfy the millennium development goals, the objectives of NEPAD and the African Union, and the agreements regulating international trade. The relevance of the veterinary profession internationally is currently subject to profound scrutiny. Its contributions are assessed against major environmental, demographic, political, disease, technological and economic needs. The scope of veterinary training in future will have to emphasise veterinary public health, food safety, emerging diseases, international trade, bioterrorism, and biomedical research, within the context of a one-health system focusing on the interface between wildlife, domesticated animals, humans, and their environment. Within the context of time available, it would mean reducing the time allocated to training in the field of companion animals. A brief history and scope of veterinary education; current international trends in veterinary education and provisioning; and some perspectives on future veterinary training and initiatives applicable to Africa are provided.

In an ageing world, maintaining good health and independence for as long as possible is essential. Instead of hospitalization or institutionalization, the elderly and disabled can be assisted in their own environment 24h a day with numerous 'smart' devices. The concept of the smart home is a promising and cost-effective way of improving home care for the elderly and the disabled in a non-obtrusive way, allowing greater independence, maintaining good health and preventing social isolation. Smart homes are equipped with sensors, actuators, and/or biomedical monitors. The devices operate in a network connected to a remote centre for data collection and processing. The remote centre diagnoses the ongoing situation and initiates assistance procedures as required. The technology can be extended to wearable and in vivo implantable devices to monitor people 24h a day both inside and outside the house. This review describes a selection of projects in developed countries on smart homes examining the various technologies available. Advantages and disadvantages, as well as the impact on modern society, are discussed. Finally, future perspectives on smart homes as part of a home-based health care network are presented.

2016-07-01

Recently, the concept of interfascial planes has become the prevalent theory among radiologists for understanding the retroperitoneal anatomy, having replaced the classic tricompartmental theory. However, it is a little known fact that the concept remains incomplete and includes embryological errors, which have been revised on the basis of our microscopic study. We believe that the concept not only provides a much clearer understanding of the retroperitoneal anatomy, but it also allows further development for diagnosis and treatment of retroperitoneal injuries and diseases, should it become an accomplished theory. We explain the history and outline of the concept of interfascial planes, correct common misunderstandings about the concept, explain the unconsciously applied therapeutic procedures based on the concept, and present future perspectives of the concept using our published and unpublished data. This knowledge could be essential to acute care physicians and surgeons sometime soon.

Micronutrient bioavailability: Dietary Reference Intakes and a future perspective1234

Science.gov (United States)

2010-01-01

This article provides a review of how the challenge of bioavailability was approached in establishing the Dietary Reference Intakes, with a special focus on folic acid, vitamin B-12, β-carotene, iron, selenium, and zinc, the targeted micronutrients for this workshop. In a future perspective, the necessity of having a clear working definition of bioavailability is emphasized. The bioavailability of micronutrients should be considered, with advantage, under subheadings determined by the broad factors that affect bioavailability. Special emphasis is given to giving greater and specific attention to factors involved in the maintenance of homeostasis. These factors, it is argued, are best considered separately from even a broad definition of bioavailability and have the potential to provide new insights into some micronutrient requirements.

Sansbury, Brittany; Dasgupta, Abhijit; Guthrie, Lori; Ward, Michael

2014-04-01

The study determined if time perspective was associated with medication adherence among people with hypertension and diabetes. Using the Health Beliefs Model, we used path analysis to test direct and indirect effects of time perspective and health beliefs on adherence among 178 people who participated in a community-based survey near Washington, D.C. We measured three time perspectives (future, present fatalistic, and present hedonistic) with the Zimbardo Time Perspective Inventory and medication adherence by self-report. The total model demonstrated a good fit (RMSEA=0.17, 90% CI [0.10, 0.28], p=0.003; comparative fit index=0.91). Future time perspective and age showed direct effects on increased medication adherence; an increase by a single unit in future time perspective was associated with a 0.32 standard deviation increase in reported adherence. There were no significant indirect effects of time perspective with reported medication adherence through health beliefs. The findings provide the first evidence that time perspective plays an under-recognized role as a psychological motivator in medication adherence. Patient counseling for medication adherence may be enhanced if clinicians incorporate consideration of the patient's time perspective. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

[Diagnosis and Treatment of Peptic Ulcer Disease: Present and Future Perspective].

Science.gov (United States)

Kim, Byung Wook

2016-06-25

Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

PET/MRI of central nervous system: current status and future perspective

2016-01-01

Imaging plays an increasingly important role in the early diagnosis, prognosis prediction and therapy response evaluation of central nervous system (CNS) diseases. The newly emerging hybrid positron emission tomography/magnetic resonance imaging (PET/MRI) can perform ''one-stop-shop'' evaluation, including anatomic, functional, biochemical and metabolic information, even at the molecular level, for personalised diagnoses and treatments of CNS diseases. However, there are still several problems to be resolved, such as appropriate PET detectors, attenuation correction and so on. This review will introduce the basic physical principles of PET/MRI and its potential clinical applications in the CNS. We also provide the future perspectives for this field. (orig.)

2015-02-01

Researchers have investigated the implications of social change for human development from different perspectives. The studies published in this special section were conducted within Greenfield's theoretical framework (2009). The findings concerning links between specific sociodemographic features (e.g., commercial activities, schooling) and individual cognition and social behaviour are particularly interesting because they tap the underlying forces that drive human development. To further understand the issues in these studies and in the field, a pluralist-constructive perspective is discussed, which emphasises the integration of diverse values and practices in both Western and non-Western societies and its effects on the development of sophisticated competencies in individual adaptation to the changing global community. In addition, several issues are highlighted and some suggestions are provided for future explorations in this field. © 2014 International Union of Psychological Science.

Magnetic tomography - newer picture techniques and perspectives for the future

International Nuclear Information System (INIS)

Gjesdal, Kjell-Inge; Smith, Hans-Joergen

2000-01-01

Background: From the very introduction of MRI into medicine, the modality has presented the user a long list of theoretical tissue contrast parameters. The development of MRI has been aimed at turning these theoretical possibilities into practical options. Material and method: We give an overview of the new MRI techniques and perspectives for the future based on literature search and our own experience. Results: Today, the modality offers state-of-the-art anatomical details as well as visualisation of several functional parameters such as perfusion, diffusion, blood oxygen saturation and tissue temperature. In the near future, MRI may provide absolute quantification of regional perfusion and rate of oxygen consumption in a clinical setting. New vascular and gastrointestinal contrast media will further increase the sensitivity and specificity of MRI. A continuous increase in imaging speed has made MRI capable of providing adequate ''fluoroscopic'' guidance during interventional procedures and real-time diagnostic imaging is only few years ahead. Interpretation: The spread of MRI installations will increase as a result of increasing demand for the best and least harmful diagnostic procedure. The main challenge to the MRI community will be to exploit the vast diagnostic possibilities

The aim of this article is to explore the future of qualitative research as seen from a students' perspective. This exploration will initially be incited through a discussion of the use of the term 'qualitative research', and the risks associated with the use of such an umbrella term. It is discussed that the use of an overarching umbrella term can lead to an overhomogenized understanding of qualitative research, that fails to represent the diversity and variety of methodological and epistemological approaches that exist within this research paradigm. It is also discussed that this overhomogenization reinforces the idea of qualitative research as an anti-doctrine to quantitative research, which is argued to discourage interparadigmatic integration. Lastly, it is considered how these (mis)conceptions of qualitative research influence how psychology students are taught about research methodology and how this education could affect these (mis)conceptions. We advocate that the future for qualitative research in psychology should be ensured through a restructure and a refocus on an educational level. This change should overall be centered around teaching students how to be reflective research practitioners based on an in-depth understanding of the variety of epistemologies within both meta-research-paradigms.

Fusion-fission dynamics and perspectives of future experiments

International Nuclear Information System (INIS)

Zagrebaev, V.I.; Itkis, M.G.; Oganessian, Yu.Ts.

2003-01-01

The paper is focused on reaction dynamics of superheavy-nucleus formation and decay at beam energies near the Coulomb barrier. The aim is to review the things we have learned from recent experiments on fusion-fission reactions leading to the formation of compound nuclei with Z ≥ 102 and from their extensive theoretical analysis. Major attention is paid to the dynamics of formation of very heavy compound nuclei taking place in strong competition with the process of fast fission (quasifission). The choice of collective degrees of freedom playing a fundamental role and finding the multidimensional driving potential and the corresponding dynamic equation regulating the whole process are discussed. A possibility of deriving the fission barriers of superheavy nuclei directly from performed experiments is of particular interest here. In conclusion, the results of a detailed theoretical analysis of available experimental data on the 'cold' and 'hot' fusion-fission reactions are presented. Perspectives of future experiments are discussed along with additional theoretical studies in this field needed for deeper understanding of the fusion-fission processes of very heavy nuclear systems

Time perspective and socioeconomic status: a link to socioeconomic disparities in health?

Guthrie, Lori C; Butler, Stephen C; Ward, Michael M

2009-06-01

Time perspective is a measure of the degree to which one's thinking is motivated by considerations of the future, present, or past. Time perspective has been proposed as a potential mediator of socioeconomic disparities in health because it has been associated with health behaviors and is presumed to vary with socioeconomic status. In this cross-sectional community-based survey of respondents recruited from hair salons and barber shops in a suburb of Washington DC, we examined the association between time perspective and both education level and occupation. We asked participants (N=525) to complete a questionnaire that included three subscales (future, present-fatalistic, and present-hedonistic) of the Zimbardo Time Perspective Inventory. Participants with more formal education and those with professional occupations had higher scores on the future time perspective subscale, and lower scores on the present-fatalistic subscale, than participants with less formal education or a non-professional occupation. Present-fatalistic scores were also higher among participants whose parents had less formal education. Present-hedonistic scores were not associated with either education level or professional occupation. Time perspective scores were not independently associated with the likelihood of obesity, smoking, or exercise. In this community sample, future time perspective was associated with current socioeconomic status, and past-fatalistic time perspective was associated with both current and childhood socioeconomic status.

Performance measurement for information systems: Industry perspectives

Science.gov (United States)

Bishop, Peter C.; Yoes, Cissy; Hamilton, Kay

1992-01-01

Performance measurement has become a focal topic for information systems (IS) organizations. Historically, IS performance measures have dealt with the efficiency of the data processing function. Today, the function of most IS organizations goes beyond simple data processing. To understand how IS organizations have developed meaningful performance measures that reflect their objectives and activities, industry perspectives on IS performance measurement was studied. The objectives of the study were to understand the state of the practice in IS performance techniques for IS performance measurement; to gather approaches and measures of actual performance measures used in industry; and to report patterns, trends, and lessons learned about performance measurement to NASA/JSC. Examples of how some of the most forward looking companies are shaping their IS processes through measurement is provided. Thoughts on the presence of a life-cycle to performance measures development and a suggested taxonomy for performance measurements are included in the appendices.

Differing perspectives of major oil firms on future energy developments: An illustrative framework

International Nuclear Information System (INIS)

Chang Youngho; Yong Jiayun

2007-01-01

This study develops a framework to analyse the perspectives of major oil firms in terms of their perceptions of current energy developments and projections of future energy potentials, and illustrates their views on the possibility of a paradigm shift in fuel use. The three A's themes-availability of resource (AV), applicability of technology (AP) and acceptability by society (AC)-make up the analytical framework. Divergence in oil firms' behaviour and perspectives are captured by the 3-A triangle that illustrates how the four largest oil firms in the world balance their stakes among the three A's. ExxonMobil's position is markedly skewed towards the theme of AV, whilst BP has the most balanced approach among the four. Shell and Total both share a similarly shaped 3-A triangle with more stakes placed on the theme of AP. The results would imply that a paradigm shift in resource use or a full-scale transition to a backstop technology is unlikely in the coming decades

Imaging plays an increasingly important role in the early diagnosis, prognosis prediction and therapy response evaluation of central nervous system (CNS) diseases. The newly emerging hybrid positron emission tomography/magnetic resonance imaging (PET/MRI) can perform ''one-stop-shop'' evaluation, including anatomic, functional, biochemical and metabolic information, even at the molecular level, for personalised diagnoses and treatments of CNS diseases. However, there are still several problems to be resolved, such as appropriate PET detectors, attenuation correction and so on. This review will introduce the basic physical principles of PET/MRI and its potential clinical applications in the CNS. We also provide the future perspectives for this field. (orig.)

Measurement trends for future safeguards systems

International Nuclear Information System (INIS)

Baloga, S.M.; Hakkila, E.A.

1980-01-01

Safeguards for future commercial-scale nuclear facilities may employ three materials control and accounting concepts: classical accounting, dynamic materials balancing, and independent verification of inventories and materials balances. Typical measurement needs associated with the implementation of these concepts at high-throughput facilities are discussed. Promising measurement methods for meeting these needs are described and recent experience is cited. General directions and considerations for meeting advanced safeguards systems needs through measurement technology development over the next decade are presented

Emittance Measurements For Future LHC Beams Using The PS Booster Measurement Line

CERN Document Server

Abelleira, Jose; Mikulec, Bettina; Di Giovanni, Gian Piero; CERN. Geneva. ATS Department

2017-01-01

The CERN PS Booster measurement line contains three pairs of SEM grids separated by drift space that measures the beam size in both planes. The combined analysis of these grids allows calculating a value for the transverse beam emittances. The precision of such a measurement depends on the ratio of RMS beam size and wire spacing. Within the LIU-PSB upgrade the extraction kinetic energy of the PSB will be increased from the current 1.4 GeV to 2.0 GeV. This will result in smaller transverse beam sizes for some of the future beams. The present layout of the transverse emittance measurement line is reviewed to verify if it will satisfy future requirements.

Mcintyre, Robert M.

1990-01-01

The present research effort was the first phase of a study to forecast whether technological obsolescence will be a problem for the engineers, scientists, and technicians at NASA Langley Research Center (LaRC). There were four goals of the research: to review the literature on technological obsolescence; to determine through interviews of division chiefs and branch heads Langley's perspective on future technological obsolescence; to begin making contacts with outside industries to find out how they view the possibility of technological obsolescence; and to make preliminary recommendations for dealing with the problem. A complete description of the findings of this research can be reviewed in a technical report in preparation. The following are a small subset of the key findings of the study: NASA's centers and divisions vary in their missions and because of this, in their capability to control obsolescence; research-oriented organizations within NASA are believed by respondents to keep up to date more than the project-oriented organizations; asked what are the signs of a professional's technological obsolescence, respondents had a variety of responses; top performing scientists were viewed as continuous learners, keeping up to date by a variety of means; when asked what incentives were available to aerospace technologists for keeping up to data, respondents specified a number of ideas; respondents identified many obstacles to professionals' keeping up to date in the future; and most respondents expressed some concern for the future of the professionals at NASA vis a vis the issue of professional obsolescence.

Using Balanced Time Perspective to Explain Well-Being and Planning in Retirement

Mooney, Anna; Earl, Joanne K.; Mooney, Carl H.; Bateman, Hazel

2017-01-01

The notion of whether people focus on the past, present or future, and how it shapes their behavior is known as Time Perspective. Fundamental to the work of two of its earliest proponents, Zimbardo and Boyd (2008), was the concept of balanced time perspective and its relationship to wellness. A person with balanced time perspective can be expected to have a flexible temporal focus of mostly positive orientations (past-positive, present-hedonistic, and future) and much less negative orientations (past-negative and present-fatalistic). This study measured deviation from balanced time perspective (DBTP: Zhang et al., 2013) in a sample of 243 mature adults aged 45 to 91 years and explored relationships to Retirement Planning, Depression, Anxiety, Stress, Positive Mood, and Negative Mood. Results indicate that DBTP accounts for unexplained variance in the outcome measures even after controlling for demographic variables. DBTP was negatively related to Retirement Planning and Positive Mood and positively related to Depression, Anxiety, Stress, and Negative Mood. Theoretical and practical implications regarding balanced time perspective are discussed. PMID:29081757

Tobacco Control Measures to Reduce Socioeconomic Inequality in Smoking: The Necessity, Time-Course Perspective, and Future Implications.

Science.gov (United States)

Tabuchi, Takahiro; Iso, Hiroyasu; Brunner, Eric

2018-04-05

Previous systematic reviews of population-level tobacco control interventions and their effects on smoking inequality by socioeconomic factors concluded that tobacco taxation reduce smoking inequality by income (although this is not consistent for other socioeconomic factors, such as education). Inconsistent results have been reported for socioeconomic differences, especially for other tobacco control measures, such as smoke-free policies and anti-tobacco media campaigns. To understand smoking inequality itself and to develop strategies to reduce smoking inequality, knowledge of the underlying principles or mechanisms of the inequality over a long time-course may be important. For example, the inverse equity hypothesis recognizes that inequality may evolve in stages. New population-based interventions are initially primarily accessed by the affluent and well-educated, so there is an initial increase in socioeconomic inequality (early stage). These inequalities narrow when the deprived population can access the intervention after the affluent have gained maximum benefit (late stage). Following this hypothesis, all tobacco control measures may have the potential to reduce smoking inequality, if they continue for a long term, covering and reaching all socioeconomic subgroups. Re-evaluation of the impact of the interventions on smoking inequality using a long time-course perspective may lead to a favorable next step in equity effectiveness. Tackling socioeconomic inequality in smoking may be a key public health target for the reduction of inequality in health.

Although several previous studies have shown that individuals' attitude towards time could affect their intertemporal preference, little is known about the neural basis of the relation between time perspective (TP) and delay discounting. In the present study, we quantified the gray matter (GM) cortical volume using voxel-based morphometry (VBM) methods to investigate the effect of TP on delay discounting (DD) across two independent samples. For group 1 (102 healthy college students; 46 male; 20.40 ± 1.87 years), behavioral results showed that only Future TP was a significant predictor of DD, and higher scores on Future TP were related to lower discounting rates. Whole-brain analysis revealed that steeper discounting correlated with greater GM volume in the ventromedial prefrontal cortex (vmPFC) and ventral part of posterior cingulate cortex (vPCC). Also, GM volume of a cluster in the vmPFC was correlated with Future TP. Interestingly, there was an overlapping region in vmPFC that was correlated with both DD and Future TP. Region-of-interest analysis further indicated that the overlapping region of vmPFC played a partially mediating role in the relation between Future TP and DD in the other independent dataset (Group 2, 36 healthy college students; 14 male; 20.18±1.80 years). Taken together, our results provide a new perspective from neural basis for explaining the relation between DD and future TP. Copyright © 2017 Elsevier Ltd. All rights reserved.

Measuring workload in collaborative contexts: trait versus state perspectives.

Helton, William S; Funke, Gregory J; Knott, Benjamin A

2014-03-01

In the present study, we explored the state versus trait aspects of measures of task and team workload in a disaster simulation. There is often a need to assess workload in both individual and collaborative settings. Researchers in this field often use the NASATask Load Index (NASA-TLX) as a global measure of workload by aggregating the NASA-TLX's component items. Using this practice, one may overlook the distinction between traits and states. Fifteen dyadic teams (11 inexperienced, 4 experienced) completed five sessions of a tsunami disaster simulator. After every session, individuals completed a modified version of the NASA-TLX that included team workload measures.We then examined the workload items by using a between-subjects and within-subjects perspective. Between-subjects and within-subjects correlations among the items indicated the workload items are more independent within subjects (as states) than between subjects (as traits). Correlations between the workload items and simulation performance were also different at the trait and state levels. Workload may behave differently at trait (between-subjects) and state (within-subjects) levels. Researchers interested in workload measurement as a state should take a within-subjects perspective in their analyses.

Full Text Available Purpose: To facilitate futures business research by proposing a novel way to combine business models as a conceptual tool with futures research techniques. Design: A futures perspective is adopted to foresight business models of the Internet of Things (IoT enabled healthcare sector by using business models as a futures business research tool. In doing so, business models is coupled with one of the most prominent foresight methodologies, Causal Layered Analysis (CLA. Qualitative analysis provides deeper understanding of the phenomenon through the layers of CLA; litany, social causes, worldview and myth. Findings: It is di cult to predict the far future for a technology oriented sector like healthcare. This paper presents three scenarios for short-, medium- and long-term future. Based on these scenarios we also present a set of business model elements for different future time frames. This paper shows a way to combine business models with CLA, a foresight methodology; in order to apply business models in futures business research. Besides offering early results for futures business research, this study proposes a conceptual space to work with individual business models for managerial stakeholders. Originality / Value: Much research on business models has offered conceptualization of the phenomenon, innovation through business model and transformation of business models. However, existing literature does not o er much on using business model as a futures research tool. Enabled by futures thinking, we collected key business model elements and building blocks for the futures market and ana- lyzed them through the CLA framework.

1996-01-01

After a brief description of the broad and comprehensive knowledge base in incipient failure detection and on-line diagnostics at Institut fuer Sicherheitstechnologie ISTec, the international situation is reflected, and the operational needs as known from all the regular services of ISTec are discussed. ISTec has been involved in signal analyses, diagnosis support, and surveillance services. Long-term trending of signatures and features are performed, signature data banks with reference and fault-effected signatures were built up, a diagnosis center with advanced support tools has been established. The emphasis is placed on the development necessary in future to cope with the operator's interests. Most of the recent R and D work, aimed at the implementation of new information processing tools and techniques, will need time to be accepted in practice (long-term perspectives). Therefore, the actions and developments described under short-term perspectives should be pushed in order to progress in on-line NPP early failure diagnostics. (author)

Human factors measurement for future air traffic control systems.

Langan-Fox, Janice; Sankey, Michael J; Canty, James M

2009-10-01

This article provides a critical review of research pertaining to the measurement of human factors (HF) issues in current and future air traffic control (ATC). Growing worldwide air traffic demands call for a radical departure from current ATC systems. Future systems will have a fundamental impact on the roles and responsibilities of ATC officers (ATCOs). Valid and reliable methods of assessing HF issues associated with these changes, such as a potential increase (or decrease) in workload, are of utmost importance for advancing theory and for designing systems, procedures, and training. We outline major aviation changes and how these relate to five key HF issues in ATC. Measures are outlined, compared, and evaluated and are followed by guidelines for assessing these issues in the ATC domain. Recommendations for future research are presented. A review of the literature suggests that situational awareness and workload have been widely researched and assessed using a variety of measures, but researchers have neglected the areas of trust, stress, and boredom. We make recommendations for use of particular measures and the construction of new measures. It is predicted that, given the changing role of ATCOs and profound future airspace requirements and configurations, issues of stress, trust, and boredom will become more significant. Researchers should develop and/or refine existing measures of all five key HF issues to assess their impact on ATCO performance. Furthermore, these issues should be considered in a holistic manner. The current article provides an evaluation of research and measures used in HF research on ATC that will aid research and ATC measurement.

Adults' future time perspective predicts engagement in physical activity.

Stahl, Sarah T; Patrick, Julie Hicks

2012-07-01

Our aim was to examine how the relations among known predictors of physical activity, such as age, sex, and body mass index, interact with future time perspective (FTP) and perceived functional limitation to explain adults' engagement in physical activity. Self-report data from 226 adults (range 20-88 years) were collected to examine the hypothesis that a more expansive FTP is associated with engagement in physical activity. Results indicated a good fit of the data to the model χ(2) (4, N = 226) = 7.457, p = .14 and accounted for a moderate amount of variance in adults' physical activity (R(2) = 15.7). Specifically, results indicated that perceived functional limitation (β = -.140) and FTP (β = .162) were directly associated with physical activity. Age was indirectly associated with physical activity through its association with perceived functional limitation (β = -.264) and FTP (β = .541). Results indicate that FTP may play an important role in explaining engagement in health promoting behaviors across the life span. Researchers should consider additional constructs and perhaps adopt socioemotional selectivity theory when explaining adults' engagement in physical activity.

Full Text Available Background: Trusts have long been used as an estate planning mechanism, including the avoidance of estate duty and donations tax. In the 2016 National Budget the Minister of Finance indicated that Government was proposing several legislative measures during 2016/2017 to prevent individuals from using a trust to avoid estate duty (and donations tax to a certain extent. Unexpectedly, the 2016 draft Taxation Laws Amendment Bill and the final Amendment Bill did not give effect to any of these proposals, but introduced other less drastic measures to control the abuse of trusts for tax purposes, albeit with the same stated purpose. Aim: The main aim of the study was to clarify the reform proposals (albeit unclear and consequently based on certain assumptions and to compare the reform proposals with the final amendments. This comparison will shed some light on the fairness and appropriateness of the final amendments and, more importantly, on the possibility that the reform proposals published by National Treasury in February 2016 not included in the final amendments will be enacted in the future. This investigation will assist tax practitioners and taxpayers in effective tax and estate planning, given that the reform proposals and final amendments have a possible impact on the future of discretionary trusts in South Africa. Setting: This article examines existing literature in a South African income tax environment. Methods: In order to meet this objective a qualitative approach based on a literature study of pure theoretical aspects was used. Results and conclusion: It was found that should the reform proposals become law, many trusts would become ineffective from a tax-planning perspective and these changes might erode other benefits trusts offer, jeopardising the future of discretionary trusts in South Africa.

Cancer is a major threat to public health in the 21st century because it is one of the leading causes of death worldwide. The mechanisms of carcinogenesis, cancer invasion, and metastasis remain unclear. Thus, the development of a novel approach for cancer detection is urgent, and real-time monitoring is crucial in revealing its underlying biological mechanisms. With the optical and chemical advantages of quantum dots (QDs), QD-based nanotechnology is helpful in constructing a biomedical imaging platform for cancer behavior study. This review mainly focuses on the application of QD-based nanotechnology in cancer cell imaging and tumor microenvironment studies both in vivo and in vitro, as well as the remaining issues and future perspectives

To summarize current training guidelines for cardiac imaging and provide recommendations for future guidelines. The current structure of training in cardiac imaging is largely dictated by modality-specific guidelines. While there has been debate on how to define the advanced cardiac imager for over a decade, a uniform consensus has not emerged. We report the perspectives of three key stakeholders in this debate: a senior faculty member-former fellowship program director, a cardiology fellow, and an academic junior faculty imaging expert. The observations of these stakeholders suggest that there is no consensus on the definition of advanced cardiac imaging, leading to ambiguity in training guidelines. This may have negative impact on recruitment of fellows into cardiac imaging careers. Based on the current status of training in cardiac imaging, the authors suggest that the relevant professional groups reconvene to form a consensus in defining advanced cardiac imaging, in order to guide future revisions of training guidelines.

This study tested whether time perspective, a central tenant of socioemotional selectivity theory (Carstensen, 2006), moderates positivity effects in emotional memory. To provide measures of time perspective, young (YA; M = 22.48 years), young-old (YO; M = 67.56 years), old-old adults (OO; M = 80.24 years), and participants with moderate severity Alzheimer's disease (PAD; M = 84.28 years) completed a line task and reported subjective age. As expected, YA, YO, and OO reported successively more constrained future time perspectives. PAD showed distortion in time perspective, envisioning a future comparable with the YO, although closer matched in chronological age to OO adults. To evince positivity effects, participants were oriented to pairs of emotional images and were then tested for memory (recall and recognition) of the images. Recall and recognition memory for the images indicated an age-related advantage for positive over negative material (positivity effects). Time perspective, however, did not moderate these age effects. In memory performance, PAD were more comparable with OO adults with whom they shared a similar chronological age, rather than YO adults, who had a corresponding time perspective. These results suggest that age correlates that are shared by PAD and OO, such as reduced processing resources, rather than time perspective, may drive the age associated positivity effects.

2003-01-01

The neutron environment inside spacecraft has been of interest from a scientific and radiation protection perspective since early in the history of manned spaceflight. With 1:.1e exception of a few missions which carried plutonium-fueled radioisotope thermoelectric generators, all of the neutrons inside the spacecraft are secondary radiations resulting from interactions of high-energy charged particles with nuclei in the Earth's atmosphere, spacecraft structural materials, and the astronaut's own bodies. Although of great interest, definitive measurements of the spacecraft neutron field have been difficult due to the wide particle energy range and the limited available volume and power for traditional techniques involving Bonner spheres. A multitude of measurements, however, have been made of the neutron environment inside spacecraft. The majority of measurements were made using passive techniques including metal activation fo ils, fission foils, nuclear photoemulsions, plastic track detectors, and thermoluminescent detectors. Active measurements have utilized proton recoil spectrometers (stilbene), Bonner Spheres eRe proportional counter based), and LiI(Eu)phoswich scintillation detectors. For the International Space Station (ISS), only the plastic track! thermoluminescent detectors are used with any regularity. A monitoring program utilizing a set of active Bonner spheres was carried out in the ISS Lab module from March - December 200l. These measurements provide a very limited look at the crew neutron exposure, both in time coverage and neutron energy coverage. A review of the currently published data from past flights will be made and compared with the more recent results from the ISS. Future measurement efforts using currently available techniques and those in development will be also discussed.

2016-01-01

The number of computed tomography examinations has continuously increased over the last decades and accounts for a major part of the collective radiation dose from medical investigations. For purposes of quality assurance in modern radiology a systematic monitoring and analysis of dose related data from radiological examinations is mandatory. Various ways of collecting dose data are available today, for example the Digital Imaging and Communication in Medicine - Structured Report (DICOM-SR), optical character recognition and DICOM-modality performed procedure steps (MPPS). The DICOM-SR is part of the DICOM-standard and provides the DICOM-Radiation Dose Structured Report, which is an easily applicable and comprehensive solution to collect radiation dose parameters. This standard simplifies the process of data collection and enables comprehensive dose monitoring. Various commercial dose monitoring software devices with varying characteristics are available today. In this article, we discuss legal obligations, various ways to monitor dose data, current dose monitoring software solutions and future perspectives in regard to the EU Council Directive 2013/59/EURATOM.

Effects of occupational future time perspective on managing stressful work situations.

Ho, Henry C Y; Yeung, Dannii Y

2016-08-01

According to the socioemotional selectivity theory (SST; Carstensen, 2006), older adults perceive their future time as increasingly limited, which motivates them to focus more on emotional goals and prefer passive emotion-focused strategies. This study aims to investigate the effect of occupational future time perspective (OFTP) on the use of problem-solving strategies in stressful work situations and to examine the effectiveness of these strategies on psychological well-being. A sample of 199 Chinese clerical workers responded to a structured questionnaire on problem-solving strategy use in relation to hypothetical work scenarios. Results revealed that relative to those with limited OFTP, workers with expansive OFTP preferred problem-focused and proactive strategies in both low- and high-emotionally salient scenarios. Workers with limited OFTP consistently preferred passive strategies irrespective of emotional salience. OFTP moderated the effect of problem-focused strategies on psychological distress. In particular, there was a significant negative relationship between problem-focused strategies and psychological distress among workers with expansive OFTP, but such pattern of relationship was not observed among workers with limited OFTP. Findings of this study inform the training strategies employed by practitioners to fit the developmental goals of workers in order to maximise their strengths at work. © 2015 International Union of Psychological Science.

Full Text Available The purpose of the present study was to examine the present fatalistic time perspective as a mechanism that may partially account for age differences in purpose in life and personal growth. An additional purpose of this study was to explore the relations among age, time perspective, and psychological well-being. Seventy-five older adults (M=73.43, SD=7.91 and 77 younger adults (M=19.58, SD=1.19 completed surveys measuring time perspective (past positive, past negative, present fatalistic, present hedonistic, future and psychological well-being (autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance. Hierarchical regression analyses revealed that the present fatalistic time perspective predicted purpose in life and personal growth above and beyond age and income. Several significant correlations were found among the time perspective and psychological well-being variables. Results showed that age was positively correlated with the past negative and present fatalistic time perspectives, but negatively correlated with the future time perspective. Results showed that age negatively correlated with purpose in life and personal growth, but positively correlated with autonomy. Results are discussed in light of socioemotional selectivity theory, theory of time perspective, and implications for incorporating time perspective into mental health counseling.

Measuring retrograde autobiographical amnesia following electroconvulsive therapy: historical perspective and current issues.

Science.gov (United States)

Semkovska, Maria; McLoughlin, Declan M

2013-06-01

Retrograde amnesia following electroconvulsive therapy (ECT) is a major concern for both patients and clinicians. In contemporary ECT research, retrograde autobiographical amnesia (RAA) is commonly measured with instruments assessing autobiographical memory (AM) consistency over time. However, normal AM recall loses in consistency with the passage of time, and time has a differential effect on stability of personal memories. In addition, experiencing depression is associated with a decreased ability to recall specific AMs, and this difficulty may persist in the euthymic phase of recurrent depression. Despite these scientific facts, relatively few attempts have been made to accurately measure the specific effect of ECT on AM independent of both normal and mood-associated forgetting over time. This major gap in our knowledge prevents us at present from objectively quantifying the nature and extent of RAA associated with ECT. In turn, this hinders our identifying and implementing strategies for prevention or remediation of AM deficits. The present article aims to provide an up-to-date review and historical perspective of this major methodological conundrum for ECT research, highlight current issues in retrograde amnesia assessment following ECT, and propose directions for future studies. In conclusion, we suggest methods to reliably and specifically measure the extent and progression over time of ECT-associated RAA independently from persistent depressive symptoms' contribution and normal loss in AM consistency over time.

The CERN n_TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron energies, from thermal to a few GeV. These characteristics provide a unique possibility to perform high-accuracy measurements of neutron-induced reaction cross-sections and angular distributions of interest for fundamental and applied Nuclear Physics. Since 2001, the n_TOF Collaboration has collected a wealth of high quality nuclear data relevant for nuclear astrophysics, nuclear reactor technology, nuclear medicine, etc. The overall efficiency of the experimental program and the range of possible measurements has been expanded with the construction of a second experimental area (EAR-2), located 20 m on the vertical of the n_TOF spallation target. This upgrade, which benefits from a neutron flux 30 times higher than in EAR-1, provides a substantial extension in measurement capabilities, opening the possibility to collect data on neutron cross-section of isotopes with short half-lives or available in very small amounts. This contribution will outline the main characteristics of the n_TOF facility, with special emphasis on the new experimental area. In particular, we will discuss the innovative features of the EAR-2 neutron beam that make possible to perform very challenging measurements on short-lived radioisotopes or sub-mg samples, out of reach up to now at other neutron facilities around the world. Finally, the future perspectives of the facility will be presented.

Children, adolescents, and young adults (children/youth) with differences/disorders of sex development (DSD) face challenges related to future fertility; this may be due to variations in gonadal development, and, for some, gonadectomy performed to reduce the risk of malignancy. Childhood may be the only time for preservation of biological fertility potential for children/youth who undergo gonadectomy or have early gonadal failure. Fertility-related decision-making for these patients is particularly complicated, due to the need for parental proxy decision-making, potential discordance between gender identity and gonadal type, and uncertain future assisted reproductive technologies. This study aimed to assess: (1) attitudes regarding future fertility, and (2) healthcare needs for fertility-related decision-making among parents of children/youth with DSD. Semi-structured qualitative interviews about future fertility were conducted with parents of children/youth with DSD. Parents who had never discussed fertility with a healthcare provider were excluded. Grounded theory methodology was used to identify emergent themes and patterns. Demographics and clinical characteristics were assessed via survey and medical chart review. Nineteen parents were interviewed (participation rate: 60%, 14 mothers/5 fathers, median patient age at diagnosis 6 months (range 0-192), eight DSD diagnoses). The most common emergent themes are summarized in the Summary Table. Most parents identified fertility as a key concern, both at time of diagnosis and throughout development. Parents expressed difficulty with timing of disclosure about potential infertility to their children. Multiple preferences related to medical decision-making about future fertility and fertility preservation were expressed, including: a desire for step-by-step decision-making, and use of medically vetted information and research to guide decisions. This qualitative study provided new information about the perspectives of

Perceived Stress in Adults Aged 65 to 90: Relations to Facets of Time Perspective and COMT Val158Met Polymorphism.

Rönnlund, Michael; Åström, Elisabeth; Adolfsson, Rolf; Carelli, Maria G

2018-01-01

This study examined the relation between perceived stress and time perspective (views of past, present, future) in a population-based sample of older adults (65-90 years, N = 340). The Perceived Questionnaire (PSQ index) was used to measure stress and the Swedish version of the Zimbardo Time Perspective Inventory (S-ZTPI) was used to operationalize time perspective. Unlike the original inventory, S-ZTPI separates positive and negative aspects of a future time perspective and we hypothesized that the Future Negative (FN) scale would be important to account for variations in stress. Additionally, associations with Catechol-O-methyltransferase ( COMT ) Val 158 Met polymorphism were examined, motivated by prior associations of this single nucleotide polymorphism (SNP) with stress (or "anxiety") related personality traits. In line with the hypotheses, FN was the strongest predictor of PSQ index scores in multiple regression analyses. In a related vein, the dichotomization of the unitary Future scale increased the association between PSQ scores and a measure of deviations from a balanced time perspective, i.e., the difference between a proposed optimal and observed ZTPI profile. Finally, higher levels of stress as well as higher scores on FN were observed in COMT Val/Val carriers, at least among men. This suggests a shared dopaminergic genetic influence on these variables. Collectively, the results demonstrate that perceived stress is closely linked to time perspective and highlight the need to take negative aspects of a future temporal orientation into account to understand this relation.

Toth, Sheree L.; Gravener-Davis, Julie A.; Guild, Danielle J.; Cicchetti, Dante

2014-01-01

It is well established that child maltreatment has significant deleterious effects for the individual as well as for society. We briefly review research regarding the impact of child maltreatment on the attachment relationship, highlighting the need for relational interventions for maltreated children and their families to effectively thwart negative developmental cascades that are so often observed in the context of child maltreatment. Next, historical and contemporaneous perspectives on relational interventions for individuals with histories of child maltreatment are discussed with attention to the empirical evidence for and the current evidence-based status of several relationally based interventions for child maltreatment. Differential sensitivity to the environment is then discussed as a theoretical framework with important implications for interventions for individuals who have been reared in maltreating environments. Current research on neurobiology and maltreatment is then reviewed, with an emphasis on the need for future investigations on genetic variants, epigenetics, and the efficacy of relational interventions for maltreated children. We conclude with a discussion of the tenets of developmental psychopathology, their implications for relational interventions for child maltreatment, and recommendations for advancing the development, provision, and evaluation of relational interventions for individuals with histories of child maltreatment.

Full Text Available Background Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients’ life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. Method A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. Results A t-test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but

Impact of chronotype and time perspective on the processing of scripts.

Nowack, Kati; van der Meer, Elke

2014-05-01

Little is known about the impact of temporal orientation (chronotype; time perspective) on cognitive performance. This study adopted a psychophysiological approach to explore how chronotype (morningness-eveningness) and time perspective (present; future) influence time succession as another aspect of psychological time that is entailed within script knowledge. In a temporal judgment task, participants decided which of the two presented sub-events (e.g., get new batteries-set right time on alarm clock) comes earlier (or later) within a given script (e.g., changing batteries in an alarm clock). Behavioral and pupillary data suggest a differential impact of chronotype and time perspective on script knowledge and cognitive performance. The impact of time perspective on the processing of temporal information entailed in script knowledge appears linked to match or mismatch conditions between a strong focus on future outcomes associated with future time perspective and the task of identifying either the later (future-oriented) or the earlier (past-oriented) sub-event. Concerning the chronotype, evening types process items in which chronological time succession is violated (i.e., reversely presented items) more accurately than morning types. Indexed by pupillary data, the impact of chronotype may relate to more general cognitive abilities. The psychophysiological data derived in this study suggests that evening types typically outperform morning types in various measures such working memory capacity and verbal intelligence simply because they invest more cognitive resources than morning types.

Leishmaniasis is a complex of diseases with numerous clinical manifestations for instance harshness from skin lesions to severe disfigurement and chronic systemic infection in the liver and spleen. So far, the most classical leishmaniasis therapy, despite its documented toxicities, remains pentavalent antimonial compounds. The arvailable therapeutic modalities for leishmaniasis are overwhelmed with resistance to leishmaniasis therapy. Mechanisms of classical drug resistance are often related with the lower drug uptake, increased efflux, the faster drug metabolism, drug target modifications and over-expression of drug transporters. The high prevalence of leishmaniasis and the appearance of resistance to classical drugs reveal the demand to develop and explore novel, less toxic, low cost and more promising therapeutic modalities. The review describes the mechanisms of classical drug resistance and potential drug targets in Leishmania infection. Moreover, current drug-delivery systems and future perspectives towards Leishmaniasis treatment are also covered.

Assessment of lung ventilation by MR imaging: current status and future perspectives

Kauczor, Hans-Ulrich; Hanke, Alexander; Beek, Edwin J.R. van

2002-01-01

The aim of this paper is to review the present status of novel MRI techniques as a new important instrument for functional ventilation imaging. The current status and future perspectives in research and clinical applications are summarized. Morphological lung imaging is based on chest radiography and computed tomography, whereas scintigraphy is used for ventilation imaging. During recent years, MRI has emerged as a new means for functional imaging of ventilation. Aerosolized contrast agents and oxygen are used in proton imaging, whereas non-proton imaging relies on fluorine compounds, such as sulfur hexafluoride and perfluorcarbons, or on hyperpolarized noble gases, such as helium-3 or xenon-129. All the gases are administered as inhaled ''contrast agents'' for imaging of the airways and airspaces. In general, straightforward images demonstrate the homogeneity of ventilation in a breath-hold and allow for determination of ventilated lung. The different properties of the different compounds enable the measurement of additional functional parameters. They comprise airspace size, regional oxygen partial pressure, and analysis of ventilation distribution, ventilation/perfusion ratios, and gas exchange, including oxygen uptake. Novel MRI techniques provide the potential for functional imaging of ventilation. The next steps include definition of the value and the potential of the different contrast mechanisms as well as determination of the significance of the functional information with regard to physiological research and patient management in chronic obstructive pulmonary disease and others.

We report a history of the developments of the Monte Carlo shell model (MCSM). The MCSM was proposed in order to perform large-scale shell-model calculations which direct diagonalization method cannot reach. Since 1999 PC clusters were introduced for parallel computation of the MCSM. Since 2011 we participated the High Performance Computing Infrastructure Strategic Program and developed a new MCSM code for current massively parallel computers such as K computer. We discuss future perspectives concerning a new framework and parallel computation of the MCSM by incorporating conjugate gradient method and energy-variance extrapolation

Alternative Measures of Self-Rated Health for Predicting Mortality Among Older People: Is Past or Future Orientation More Important?

Science.gov (United States)

Ferraro, Kenneth F; Wilkinson, Lindsay R

2015-10-01

The purpose of this study was to compare the prognostic validity of alternative measures of health ratings, including those that tap temporal reflections, on adult mortality. The study uses a national sample of 1,266 Americans 50-74 years old in 1995, with vital status tracked through 2005, to compare the effect of 3 types of health ratings on mortality: conventional indicator of self-rated health (SRH), age comparison form of SRH, and health ratings that incorporate temporal dimensions. Logistic regression was used to estimate the odds of mortality associated with alternative health ratings while adjusting for health conditions, lifestyle factors, and status characteristics and resources. Self-rated health was a consistent predictor of mortality, but the respondent's expected health rating-10 years in the future-was an independent predictor. Future health expectations were more important than past (recalled change) in predicting mortality risk: People with more negative expectations of future health were less likely to survive. The findings reveal the importance of future time perspective for older people and suggest that it is more useful to query older people about their future health expectations than about how their health has changed. © The Author 2013.

McLain, David L; Kefallonitis, Efstathios; Armani, Kimberly

2015-01-01

Ambiguity tolerance is an increasingly popular subject for study in a wide variety of fields. The definition of ambiguity tolerance has changed since its inception, and accompanying that change are changes in measurement and the research questions that interest researchers. There is a wealth of opportunity for research related to ambiguity tolerance and recent advances in neuroscience, measurement, trait research, perception, problem solving, and other fields highlight areas of interest and point to issues that need further attention. The future of ambiguity tolerance research is promising and it is expected that future studies will yield new insights into individual differences in reactions to the complex, unfamiliar, confusing, indeterminate, and incomplete stimuli that fall within the conceptual domain of ambiguity.

The effect of future time perspective on procrastination: the role of parahippocampal gyrus and ventromedial prefrontal cortex.

2018-05-09

Procrastination is an almost universal affliction, which occurs across culture and brings serious consequences across multiple fields, such as finance, health and education. Previous research has showed procrastination can be influenced by future time perspective (FTP). However, little is known about the neural basis underlying the impact of FTP on procrastination. To address this question, we used voxel-based morphometry (VBM) based on brain structure. In line with previous findings, the behavioral result indicated that FTP inventory scores were significantly negatively correlated with procrastination inventory scores (r = -0.63, n = 160). The whole-brain VBM results showed that FTP scores were significantly negatively correlated with the grey matter (GM) volumes of the parahippocampal gyrus (paraPHC) and ventromedial prefrontal cortex (vmPFC) after the multiple comparisons correction. Furthermore, mediation analyses revealed that the effect of GM volumes of the paraPHC and vmPFC on procrastination was mediated by FTP. These results suggested that paraPHC and vmPFC, the critical brain regions about episodic future thinking, could be the neural basis responsible for the impact of FTP on procrastination. The present study extends our knowledge on procrastination, and provides a novel perspective to understand the relationship between FTP and procrastination.

Michael Rönnlund

2018-03-01

Full Text Available This study examined the relation between perceived stress and time perspective (views of past, present, future in a population-based sample of older adults (65–90 years, N = 340. The Perceived Questionnaire (PSQ index was used to measure stress and the Swedish version of the Zimbardo Time Perspective Inventory (S-ZTPI was used to operationalize time perspective. Unlike the original inventory, S-ZTPI separates positive and negative aspects of a future time perspective and we hypothesized that the Future Negative (FN scale would be important to account for variations in stress. Additionally, associations with Catechol-O-methyltransferase (COMT Val158Met polymorphism were examined, motivated by prior associations of this single nucleotide polymorphism (SNP with stress (or “anxiety” related personality traits. In line with the hypotheses, FN was the strongest predictor of PSQ index scores in multiple regression analyses. In a related vein, the dichotomization of the unitary Future scale increased the association between PSQ scores and a measure of deviations from a balanced time perspective, i.e., the difference between a proposed optimal and observed ZTPI profile. Finally, higher levels of stress as well as higher scores on FN were observed in COMT Val/Val carriers, at least among men. This suggests a shared dopaminergic genetic influence on these variables. Collectively, the results demonstrate that perceived stress is closely linked to time perspective and highlight the need to take negative aspects of a future temporal orientation into account to understand this relation.

Wittmann, Marc; Rudolph, Tina; Linares Gutierrez, Damisela; Winkler, Isabell

2015-12-17

Hardly any empirical work exists concerning the relationship between the intra-individually stable time perspective relating to the past, present, and future and the subjective speed of time passing in everyday life. Moreover, studies consistently show that the subjective passage of time over the period of the last ten years speeds up as we get older. Modulating variables influencing this phenomenon are still unknown. To investigate these two unresolved issues, we conducted an online survey with n = 423 participants ranging in age between 17 and 81 assessing trait time perspective of the past, present, and future, and relating these subscales with a battery of measures pertaining to the subjective passage of time. Moreover, the subjective passage of time as an age-dependent variable was probed in relationship to emotion awareness, appraisal and regulation. Results show how present hedonism is linked with having fewer routines in life and a faster passage of the last week; the past negative perspective is related to time pressure, time expansion and more routine; a pronounced future perspective is related to a general faster passage of time. Importantly, increased emotion regulation and a balanced time perspective are related to a slower passage of the last ten years. These novel findings are discussed within models of time perception and the time perspective.

Heat Shock Proteins in Vascular Diabetic Complications: Review and Future Perspective

Directory of Open Access Journals (Sweden)

Stefania Bellini

2017-12-01

Full Text Available Heat shock proteins (HSPs are a large family of proteins highly conserved throughout evolution because of their unique cytoprotective properties. Besides assisting protein refolding and regulating proteostasis under stressful conditions, HSPs also play an important role in protecting cells from oxidative stress, inflammation, and apoptosis. Therefore, HSPs are crucial in counteracting the deleterious effects of hyperglycemia in target organs of diabetes vascular complications. Changes in HSP expression have been demonstrated in diabetic complications and functionally related to hyperglycemia-induced cell injury. Moreover, associations between diabetic complications and altered circulating levels of both HSPs and anti-HSPs have been shown in clinical studies. HSPs thus represent an exciting therapeutic opportunity and might also be valuable as clinical biomarkers. However, this field of research is still in its infancy and further studies in both experimental diabetes and humans are required to gain a full understanding of HSP relevance. In this review, we summarize current knowledge and discuss future perspective.

Heavy alcohol consumption is associated with significant morbidity and mortality. Levels of alcohol consumption among students and young people are particularly high. Time perspective describes the varying value individuals place on outcomes in the present and future. In general, it has been found that individuals prefer to receive a gain today rather than in the future. There is evidence that time perspective is associated with addictive health behaviours, including alcoholism and cigarette smoking, but less evidence of its association with non-addictive, but hazardous, levels of alcohol consumption. The objective was to determine if there is an association between time perspective and hazardous alcohol consumption. A cross-sectional survey using a self-completion questionnaire was administered to willing undergraduate students attending a convenience sample of lectures in two university faculties. Hazardous alcohol consumption was defined as a score of ≥8 on the Alcohol Use Disorders Identification Test (AUDIT) and time perspective was measured using the Consideration of Future Consequences Scale (CFCS). Participants were 322 undergraduate university students in two faculties at a university in Northern England, UK. Hazardous alcohol consumption was reported by 264 (82%) respondents. After controlling for potential confounding by socio-demographic variables, greater consideration of future consequences was associated with lower odds of reporting hazardous drinking [odds ratio = 0.28; 95% confidence interval 0.15-0.54]. Interventions aimed at increasing future orientated time perspective may be effective in decreasing hazardous alcohol consumption in students.

Prophylactic and Therapeutic Vaccination against Hepatitis C Virus (HCV: Developments and Future Perspectives

Full Text Available Studies in patients and chimpanzees that spontaneously clear Hepatitis C Virus (HCV have demonstrated that natural immunity to the virus is induced during primary infections and that this immunity can be cross protective. These discoveries led to optimism regarding prophylactic HCV vaccines and a number of studies in the chimpanzee model have been performed, all of which resulted in modified infections after challenge but did not always prevent persistence of the virus. Therapeutic vaccine strategies have also been pursued in an effort to reduce the costs and side effects associated with anti-viral drug treatment. This review summarizes the studies performed thus far in both patients and chimpanzees for prophylactic and therapeutic vaccination, assesses the progress made and future perspectives.

Estimation of perspective errors in 2D2C-PIV measurements for 3D concentrated vortices

Science.gov (United States)

Ma, Bao-Feng; Jiang, Hong-Gang

2018-06-01

Two-dimensional planar PIV (2D2C) is still extensively employed in flow measurement owing to its availability and reliability, although more advanced PIVs have been developed. It has long been recognized that there exist perspective errors in velocity fields when employing the 2D2C PIV to measure three-dimensional (3D) flows, the magnitude of which depends on out-of-plane velocity and geometric layouts of the PIV. For a variety of vortex flows, however, the results are commonly represented by vorticity fields, instead of velocity fields. The present study indicates that the perspective error in vorticity fields relies on gradients of the out-of-plane velocity along a measurement plane, instead of the out-of-plane velocity itself. More importantly, an estimation approach to the perspective error in 3D vortex measurements was proposed based on a theoretical vortex model and an analysis on physical characteristics of the vortices, in which the gradient of out-of-plane velocity is uniquely determined by the ratio of the maximum out-of-plane velocity to maximum swirling velocity of the vortex; meanwhile, the ratio has upper limits for naturally formed vortices. Therefore, if the ratio is imposed with the upper limits, the perspective error will only rely on the geometric layouts of PIV that are known in practical measurements. Using this approach, the upper limits of perspective errors of a concentrated vortex can be estimated for vorticity and other characteristic quantities of the vortex. In addition, the study indicates that the perspective errors in vortex location, vortex strength, and vortex radius can be all zero for axisymmetric vortices if they are calculated by proper methods. The dynamic mode decomposition on an oscillatory vortex indicates that the perspective errors of each DMD mode are also only dependent on the gradient of out-of-plane velocity if the modes are represented by vorticity.

Today’s building energy codes focus on prescriptive requirements for features of buildings that are directly controlled by the design and construction teams and verifiable by municipal inspectors. Although these code requirements have had a significant impact, they fail to influence a large slice of the building energy use pie – including not only miscellaneous plug loads, cooking equipment and commercial/industrial processes, but the maintenance and optimization of the code-mandated systems as well. Currently, code compliance is verified only through the end of construction, and there are no limits or consequences for the actual energy use in an occupied building. In the future, our suite of energy regulations will likely expand to include building efficiency, energy use or carbon emission budgets over their full life cycle. Intelligent building systems, extensive renewable energy, and a transition from fossil fuel to electric heating systems will likely be required to meet ultra-low-energy targets. This paper lays out the authors’ perspectives on how buildings may evolve over the course of the 21st century and the roles that codes and regulations will play in shaping those buildings of the future.

A short review is made of molecular magnetism, trying to discuss what is alive and well, with perspectives for the future. All the main fields of activity are mentioned, ranging from the so-called spin cross-over systems to the quest for organic (molecular) ferromagnets. Particular attention is devoted to some of the recent advances in these fields, highlighting also the opportunities for the development of applications. Low dimensional magnets are perhaps the best opportunity to use molecules, and the status of single-molecule and single chain magnets is discussed. The last part is devoted to the organization of magnetic molecules and to the development of techniques which allow to measure the magnetic properties of thin layers and, in perspective, of single molecules.

Social and ethical perspectives of landslide risk mitigation measures

Kalsnes, Bjørn; Vangelsten, Bjørn V.

2015-04-01

Landslide risk may be mitigated by use of a wide range of measures. Mitigation and prevention options may include (1) structural measures to reduce the frequency, severity or exposure to the hazard, (2) non-structural measures, such as land-use planning and early warning systems, to reduce the hazard frequency and consequences, and (3) measures to pool and transfer the risks. In a given situation the appropriate system of mitigation measures may be a combination of various types of measures, both structural and non-structural. In the process of choosing mitigation measures for a given landslide risk situation, the role of the geoscientist is normally to propose possible mitigation measures on basis of the risk level and technical feasibility. Social and ethical perspectives are often neglected in this process. However, awareness of the need to consider social as well as ethical issues in the design and management of mitigating landslide risk is rising. There is a growing understanding that technical experts acting alone cannot determine what will be considered the appropriate set of mitigation and prevention measures. Issues such as environment versus development, questions of acceptable risk, who bears the risks and benefits, and who makes the decisions, also need to be addressed. Policymakers and stakeholders engaged in solving environmental risk problems are increasingly recognising that traditional expert-based decision-making processes are insufficient. This paper analyse the process of choosing appropriate mitigation measures to mitigate landslide risk from a social and ethical perspective, considering technical, cultural, economical, environmental and political elements. The paper focus on stakeholder involvement in the decision making process, and shows how making strategies for risk communication is a key for a successful process. The study is supported by case study examples from Norway and Italy. In the Italian case study, three different risk mitigation

Parkinson's disease (PD) is a neurodegenerative disorder resulting from the loss of dopaminergic neurons of the substantia nigra as well as degeneration of motor and nonmotor basal ganglia circuitries. Typically known for classical motor deficits (tremor, rigidity, bradykinesia), early stages of the disease are associated with a large nonmotor component (depression, anxiety, apathy, etc.). Currently, there are no definitive biomarkers of PD, and the measurement of dopamine metabolites does not allow for detection of prodromal PD nor does it aid in long-term monitoring of disease progression. Given that PD is increasingly recognized as complex and heterogeneous, involving several neurotransmitters and proteins, it is of importance that we advance interdisciplinary studies to further our knowledge of the molecular and cellular pathways that are affected in PD. This approach will possibly yield useful biomarkers for early diagnosis and may assist in the development of disease-modifying therapies. Here, we discuss preanalytical factors associated with metabolomics studies, summarize current mass spectrometric methodologies used to evaluate the metabolic signature of PD, and provide future perspectives of the rapidly developing field of MS in the context of PD.

Despite the availability of more than 15 new "antiepileptic drugs", the proportion of patients with pharmacoresistant epilepsy has remained constant at about 20-30%. Furthermore, no disease-modifying treatments shown to prevent the development of epilepsy following an initial precipitating brain injury or to reverse established epilepsy have been identified to date. This is likely in part due to the polyetiologic nature of epilepsy, which in turn requires personalized medicine approaches. Recent advances in imaging, pathology, genetics, and epigenetics have led to new pathophysiological concepts and the identification of monogenic causes of epilepsy. In the context of these advances, the First International Symposium on Personalized Translational Epilepsy Research (1st ISymPTER) was held in Frankfurt on September 8, 2016, to discuss novel approaches and future perspectives for personalized translational research. These included new developments and ideas in a range of experimental and clinical areas such as deep phenotyping, quantitative brain imaging, EEG/MEG-based analysis of network dysfunction, tissue-based translational studies, innate immunity mechanisms, microRNA as treatment targets, functional characterization of genetic variants in human cell models and rodent organotypic slice cultures, personalized treatment approaches for monogenic epilepsies, blood-brain barrier dysfunction, therapeutic focal tissue modification, computational modeling for target and biomarker identification, and cost analysis in (monogenic) disease and its treatment. This report on the meeting proceedings is aimed at stimulating much needed investments of time and resources in personalized translational epilepsy research. This Part II includes the experimental and translational approaches and a discussion of the future perspectives, while the diagnostic methods, EEG network analysis, biomarkers, and personalized treatment approaches were addressed in Part I [1].

In the treatment of stable coronary artery disease (CAD) the identification of patients who may gain the highest benefit from further invasive treatments is of pivotal importance for the healthcare system. In this setting, it has been established that an ischemia-guided revascularization strategy yields improved clinical outcomes in a cost-effective fashion compared with anatomy-guided revascularization alone. Invasive fractional flow reserve (FFR) is considered the gold standard, especially in the intermediate-range atherosclerotic lesions, for assessing lesion specific ischemia at the time of invasive coronary angiography and has now become the standard of reference for studies assessing the diagnostic performance of the various non-invasive stress tests. Coronary computed tomography angiography (cCTA) is an increasingly utilized non-invasive test that enables direct anatomical visualization of CAD in the epicardial coronary arteries with excellent sensitivity and negative predictive value. However, cCTA alone has poor specificity with FFR. With advances in computational fluid dynamics, it is possible to derive FFR from cCTA datasets improving its positive predictive value and specificity. The aim of this review is to summarize the technical aspects of FFR-CT, clinical evidence and limitations behind the novel technology, with a special focus on the recent PLATFORM Trial analyzing the effectiveness, clinical outcomes and resource utilization of FFR-CT. Finally, the future perspective of FFR-CT will be presented.

Chemicals from anthropogenic and natural origins enter animal feed, human food and water either as undesirable contaminants or as part of the components of a diet. Over the last five decades, considerable efforts and progress to develop methodologies to protect humans and animals against potential risks associated with exposure to such potentially toxic chemicals have been made. This special issue presents relevant methodological developments and examples of risk assessments of undesirable substances in the food chain integrating the animal health and the human health perspective and refers to recent Opinions of the Scientific Panel on Contaminants in the Food Chain (CONTAM) of the European Food Safety Authority (EFSA). This introductory review aims to give a comparative account of the risk assessment steps used in human health and animal health risk assessments for chemicals in the food chain and provides a critical view of the data gaps and future perspectives for this cross-disciplinary field.

Fung, Helene H; Isaacowitz, Derek M

2016-09-01

There currently appears to be a general consensus on the relationship between time perspective and aging, such that (a) future time is perceived as more limited with age and (b) older people are more present-focused and less future-focused than younger people. At the same time, there are debates about whether these age differences are positively related to well-being and to what extent there are boundary conditions beyond which these age differences would cease to occur. The 8 manuscripts included in this Special Issue attempt to shed light on these debates. In doing so, they refine the dominant theoretical perspective on the topic-socioemotional selectivity theory-and introduce new theoretical perspectives. New measures and methodologies for studying time perspective and aging are also discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Sweden's Future Climate in the short- and medium-term perspective. Basis for development of climate adaptation tools; Sveriges framtida klimat paa kort och medellaang sikt. Underlag foer utveckling av verktyg foer klimatanpassning

Energy Technology Data Exchange (ETDEWEB)

Carlsen, Henrik; Parmhed, Oskar

2008-12-15

This report studies two questions - how the actual amount of greenhouse gas emissions has changed over time in comparison with previous assumptions and what will happen to Sweden's climate from short and medium term perspectives given the future development of the climate in general. The content of this report shall be used as the basis for continued work in the development of climate adaptation tools that can be used primarily in Sweden. The first section of this report presents the development of actual greenhouse gas emissions in recent years. Eight years have passed since IPCC published its emissions scenarios (SRES) and for this reason a comparison between the emissions levels from the report and the experimental data from observations made in recent years is well due. Measurements show that current levels of emissions of carbon dioxide from fossil fuels exceed the average of the SRES families as a whole. Among other implications, this means that emission levels are significantly higher than the levels assumed in the climate scenarios of the Swedish Commission on Climate and Vulnerability (Klimat- och saarbarhetsutredningen). There is little support from the experimental data to indicate that this rate of increase will subside. In addition, studies are indicating that the increased emissions are not solely attributable to a rise in population levels and increased wealth (GNP/capita). Another aspect is that the carbon intensity, measured as the amount of carbon dioxide per unit production price, has been declining since 2000. This is entirely contrary to the assumptions made in all of the emissions scenarios in SRES that carbon dioxide efficiency would continue to increase. The report therefore concludes that work with climate adaptation in Sweden must take into consideration to a greater extent than is currently done today the consequences of emissions levels that are in line with or exceed the highest SRES levels. The second section of this report takes

End-User Attitudes towards Location-Based Services and Future Mobile Wireless Devices: The Students’ Perspective

Full Text Available Nowadays, location-enabled mobile phones are becoming more and more widespread. Various players in the mobile business forecast that, in the future, a significant part of total wireless revenue will come from Location-Based Services (LBS. An LBS system extracts information about the user’s geographical location and provides services based on the positioning information. A successful LBS service should create value for the end-user, by satisfying some of the users’ needs or wants, and at the same time preserving the key factors of the mobile wireless device, such as low costs, low battery consumption, and small size. From many users’ perspectives, location services and mobile location capabilities are still rather poorly known and poorly understood. The aim of this research is to investigate users’ views on the LBS, their requirements in terms of mobile device characteristics, their concerns in terms of privacy and usability, and their opinion on LBS applications that might increase the social wellbeing in the future wireless world. Our research is based on two surveys performed among 105 students (average student age: 24 years from two European technical universities. The survey questions were intended to solicit the youngsters’ views on present and future technological trends and on their perceived needs and wishes regarding Location-Based Services, with the aim of obtaining a better understanding of designer constraints when building a location receiver and generating new ideas related to potential future killer LBS applications.

The impact of shifting vantage perspective when recalling and imagining positive events.

Science.gov (United States)

Vella, Nicholas C; Moulds, Michelle L

2014-01-01

The vantage perspective from which memories are recalled influences their emotional impact. To date, however, the impact of vantage perspective on the emotions elicited by positive memories and images of positive future events has been minimally explored. We experimentally manipulated the vantage perspective from which a sample of undergraduate students (n =80) recalled positive memories and imagined positive future events. Participants who naturally recalled their positive memories from a field perspective reported decreased vividness and positive affect (i.e., happiness, optimism, hopefulness) when they were instructed to shift to an observer perspective. The same pattern of emotionality ratings was observed when participants' vantage perspective of imagined future events was manipulated. In contrast, shifting participants from observer to field perspective recall of positive memories did not result in changes in ratings of memory-related emotion, although we found an unexpected trend towards reduced vividness. For positive future events, shifting from an observer to a field perspective resulted in decreased vividness but did not lead to any changes in positive emotion. Our findings confirm that vantage perspective plays a key role in determining the emotional impact of positive memories, and demonstrate that this relationship is also evident for images of future positive events.

Stem Cells as New Agents for the Treatment of Infertility: Current and Future Perspectives and Challenges

Directory of Open Access Journals (Sweden)

Vladislav Volarevic

2014-01-01

Full Text Available Stem cells are undifferentiated cells that are present in the embryonic, fetal, and adult stages of life and give rise to differentiated cells that make up the building blocks of tissue and organs. Due to their unlimited source and high differentiation potential, stem cells are considered as potentially new therapeutic agents for the treatment of infertility. Stem cells could be stimulated in vitro to develop various numbers of specialized cells including male and female gametes suggesting their potential use in reproductive medicine. During past few years a considerable progress in the derivation of male germ cells from pluripotent stem cells has been made. In addition, stem cell-based strategies for ovarian regeneration and oocyte production have been proposed as future clinical therapies for treating infertility in women. In this review, we summarized current knowledge and present future perspectives and challenges regarding the use of stem cells in reproductive medicine.

Siloe and Osiris are two new general purpose research reactors of the 'Commissariat a l'energie Atomique'. Siloe, located within the 'Centre d'Etudes Nucleaires' of Grenoble is a swimming pool reactor of the same type as Melusine and Triton. It operates, at a nominal power of 15 MW thermal and has reached the peak power of 20 MW thermal with two thirds of its cooling system working. The fast flux above 1 MeV, which is maximum at the center of the core at 15 MW thermal is 1,2. 10 14 . The core, quite open, is downward cooled. Average specific power is 159 kW/l. Osiris is under construction at Saclay. Designed for 50 MW thermal, this reactor is upward cooled. The fast flux at the center of the core above 1 MeV is calculated to be 2, 5.10 14 . The average designed specific power is 280 kW/l. A fixed zircaloy gamma shield makes a box round the core. Future perspectives open to non-pressurised swimming-pool reactors are examined. Ways are suggested for neutronic; thermal and shielding modifications which make possible further improvements in the performances and economy of these devices. (authors) [fr

This review illustrates the state of the art clinical applications and the future perspectives of ultrasound elastographic methods for the evaluation of chronic liver diseases, including the most widely used and validated technique, transient elastography, followed by shear wave elastography and strain imaging elastography. Liver ultrasound elastography allows the non-invasive evaluation of liver stiffness, providing information regarding the stage of fibrosis, comparable to liver biopsy which is still considered the gold standard; in this way, it can help physicians in managing patients, including the decision as to when to start antiviral treatment. The characterization of focal liver lesions and the prognostic role of the elastographic technique in the prediction of complications of cirrhosis are still under investigation.

Status of nuclear regulatory research and its future perspectives

Lee, J. I.; Kim, W. S.; Kim, M. W.

1999-01-01

A comprehensive investigation of the regulatory research comprising an examination of the research system, its areas and contents, and the goals and financial resources is undertaken. As a result of this study, the future direction of regulatory research and its implementation strategies are suggested to resolve the current issues emerging from this examination. The major issues identified in the study are; (a) an insufficient investment in nuclear regulatory and safety research, (b) an interfacial discrepancy between similar research areas, and (c) a limitation of utilizing research results. To resolve these issues, several measures are proposed : (1) developing a lead project to establish a comprehensive infrastructure for enhancing research cooperation between nuclear organizations including institutes, industry, and universities, with an aim to improve cooperation between projects and to strengthen overall coordination functions among research projects, (2) introducing a certification system on research outcome to promote the proliferation of both research results themselves and their application with a view to enhancing the research quality, (3) strengthening the cooperative system to promote the international cooperative research, and (4) digitalizing all documents and materials relevant to safety and regulatory research to establish KIMS (knowledge and information based management system). It is expected that the aforementioned measures suggested in this study will enhance the efficiency and effectiveness of both nuclear regulatory and safety research, if they are implemented after deliberating with the government and related nuclear industries in the near future

Perspectives on future high energy physics

International Nuclear Information System (INIS)

Samios, N.P.

1996-01-01

The author states two general ways in which one must proceed in an attempt to forecast the future of high energy physics. The first is to utilize the state of knowledge in the field and thereby provide theoretical and experimental guidance on future directions. The second approach is technical, namely, how well can one do in going to higher energies with present techniques or new accelerator principles. He concludes that the future strategy is straightforward. The present accelerator facilities must be upgraded and run to produce exciting and forefront research. At the same time, the theoretical tools should be sharpened both extrapolating from lower energies (100 GeV) to high (multi TeV) and vice versa. The US should be involved in the LHC, both in the accelerator and experimental areas. There should be an extensive R and D program on accelerators for a multi-TeV capability, emphasizing e + e - and μ + μ - colliders. Finally, the international cooperative activities should be strengthened and maintained

Present status and future perspective of R and D on lead heavy metal-cooled fast reactors

International Nuclear Information System (INIS)

Takahashi, Minoru

2007-01-01

Since a lead heavy metal (lead-bismuth eutectic) is chemically inert and has higher boiling point compared to a sodium, a lead heavy metal-cooled fast reactor can be inherently safe and has good nuclear characteristics and is so suitable to a medium-small size of the reactor. R and D on corrosion of a lead heavy metal has been carried out in the world and this issue might be solved to choose specific corrosion resistant alloys for structural materials and fuel cans of a lead heavy metal-cooled reactor. This article reviews present status and future perspective on lead heavy metal-cooled fast reactors. (T. Tanaka)

Roncancio, Angelica M; Ward, Kristy K; Fernandez, Maria E

2014-12-01

To develop effective interventions to increase cervical cancer screening among Latinas, we should understand the role of cultural factors, such as time perspective, in the decision to be screened. We examined the relation between present time orientation, future time orientation, and self-reported cervical cancer screening among Latinas. A group of 206 Latinas completed a survey measuring factors associated with screening. Logistic regression analyses revealed that future time orientation was significantly associated with self-reported screening. Understanding the influence of time orientation on cervical cancer screening will assist us in developing interventions that effectively target time perspective and screening. © The Author(s) 2013.

An Experimental Evaluation of Competing Age-Predictions of Future Time Perspective between Workplace and Retirement Domains.

Science.gov (United States)

Kerry, Matthew J; Embretson, Susan E

2017-01-01

Future time perspective (FTP) is defined as "perceptions of the future as being limited or open-ended" (Lang and Carstensen, 2002; p. 125). The construct figures prominently in both workplace and retirement domains, but the age-predictions are competing: Workplace research predicts decreasing FTP age-change, in contrast, retirement scholars predict increasing FTP age-change. For the first time, these competing predictions are pitted in an experimental manipulation of subjective life expectancy (SLE). A sample of N = 207 older adults (age 45-60) working full-time (>30-h/week) were randomly assigned to SLE questions framed as either 'Live-to' or 'Die-by' to evaluate competing predictions for FTP. Results indicate general support for decreasing age-change in FTP, indicated by independent-sample t -tests showing lower FTP in the 'Die-by' framing condition. Further general-linear model analyses were conducted to test for interaction effects of retirement planning with experimental framings on FTP and intended retirement; While retirement planning buffered FTP's decrease, simple-effects also revealed that retirement planning increased intentions for sooner retirement, but lack of planning increased intentions for later retirement. Discussion centers on practical implications of our findings and consequences validity evidence in future empirical research of FTP in both workplace and retirement domains.

2017-04-01

The aim of this study was to predict acute postsurgical pain and coping with pain following surgery based on preoperative time perspectives. Time perspective is a basic dimension of psychological time. It is a tendency to focus on a particular time area: the past, the present and the future. Seventy-six patients completed measures of time perspective and pain 24 h before abdominal surgery. During the 3 days after surgery, measures of pain and coping with pain were completed. We performed hierarchical regression analyses to identify predictors of acute postsurgical pain and how patients cope with it. These analyses suggested that a preoperative past-negative time perspective can be a predictor of postoperative pain level and catastrophizing after surgery. The findings of our study indicate the importance of time perspective, especially the past perspective, in dealing with postoperative pain. Our research indicates that a preoperative past-negative time perspective is a significant predictor of acute postsurgical pain intensity and the strongest predictor of pain catastrophizing. © 2016 European Pain Federation - EFIC®.

Advocacy: Perspectives of Future Nurse Administrators.

Science.gov (United States)

OʼConnor, Mary

Advocacy is a core competency of the nurse, and especially the nurse leader. It is a multidimensional concept that requires knowledge, experience, self-confidence, and above all, courage. This article describes and illustrates the perspectives of nursing administration graduate students, as they depict advocacy in many relationships. These include advocacy for the patient, family, self, community, organization, profession, and society. The themes that emerged from narratives written by these nurse leaders were the development of courage and the finding of their voices. Stories demonstrate participants' courage to speak up despite feeling conflicted due to issues of autonomy, moral distress, or fear of retribution. Implications for nurse administrators to support advocacy at all levels are presented.

For or Against the Eurozone? Romanian Students’ Perspective on the Economic Crisis and Their Future as European Citizens

2014-10-01

Full Text Available In the context of globalization and of the aftermath of the economic crisis, the pillars on which the EU stands no longer satisfy the demands and necessities of the European citizens (Van Ham, 2005; Habermas, 2012.  The euro crisis has generated, on one hand, a gap between the “center” and the “periphery” that can be correlated with the fragmentation both of the EU’s spheres of influence and of the European financial market (Dobrescu & Palada, 2012; EFCR, 2013.  On the other hand, the euro crisis has generated a lack of solidarity and confidence in the European project. At this point, the major challenge for the European Union is not only the Euro-zone crisis, but also the level of confidence amongst young people. Recent polls (Gallup, 2013; Pew Research Center, 2013 indicate a dramatic rise in pessimism among Europe’s young people that have been labeled as “the Lost Generation” (European Commission, 2012. This paper explores the impact of the economic crisis on Romanian students’ attitudes towards the future of the European project and towards their European identity. The study aims at identifying the major concerns of Romanian students in terms of their future as European citizens. Our approach of this subject covers two perspectives: the first one is the utilitarian perspective, that is taking into consideration the actual advantages of the Europeanization process and the sustainability of the European social and economic model in the current national economic context; the second one is the identity perspective, that is taking into account the impact of the economic crisis on the Romanian students’ sense of belonging to the European community. The results of our study indicate that, overall, the Romanian youth holds an optimistic view concerning the EU, however they express some concerns in terms of lack of solidarity and fear of national identity loss.

RACK1 is a scaffolding protein and a member of the WD repeat family of proteins. These proteins have a unique architectural assembly that facilitates protein anchoring and the stabilisation of protein activity. A large body of evidence is accumulating which is helping to define the versatile role of RACK1 in assembling and dismantling complex signaling pathways from the cell membrane to the nucleus in health and disease. In this commentary, we first provide a historical perspective on RACK1. We also address many of the pertinent and topical questions about this protein such as its role in transcription, epigenetics and translation, its cytoskeletal contribution and the merits of targeting RACK1 in disease.

Unique food products constitute a very important element of European food business, culture, identity and heritage. Understanding the uniqueness of food in Europe from a research-based interdisciplinary perspective will be a critical factor in promoting the competitiveness of artisanal food industries going forward both locally and internationally. Success will support the competitiveness of the European food industry, in particular, small and medium enterprises, by enabling substantial product differentiation potential for producers and providing ample variety in food choice for the consumer. In addition, it will contribute to promotion of sustainable agriculture and development of rural areas, protecting them from depopulation. In order to meet the demands of a developing fundamental shift in European Union agricultural focus to greener, sustainable farming practices and wider rural development and to ensure success for local small-scale producers, this paper discusses the future direction of research in the field of unique European foods. The paper presents a perspective which promotes optimisation and innovation in unique food products in Europe through the integration of advanced knowledge and technologies. A framework is presented covering location, identity, perception and well-being as research areas needing synergy to bridge the research knowledge deficit in determination and specification of food identity in the European Union. The ultimate aim being promotion of sustainable agriculture and rural development, particularly in territories across the European Union where unique food is strategically and scientifically under-defined. © 2013 Society of Chemical Industry.

I think of Ronald Reagan: future selves in the present.

Science.gov (United States)

Roberts, P

1992-01-01

A nonlinear perspective on time (where the future exists in and affects the present) has been described by several theorists but there is little research on the extent, quality or origins of the personal future perspective. The present study examined the existence and origin of the future in the present by asking adults aged nineteen to eighty-three to: 1) project themselves into the oldest age imaginable, 2) describe their hopes and fears for that age, and 3) name role models for those hopes and fears. Data analysis revealed that length of future perspective, number of hopes and number of role models for the distant future declined with age. In addition, types of fears for the future varied with age, with older adults stressing dependency issues while younger adults reported concerns about personality and mental health. Despite age differences, most participants could name role models for both their hopes and fears for aging, but specific models were identified more often for hopes than for fears. Personalized hopes and fears for the distant future as motivators for the present are discussed.

Time perspective as a determinant of smoking cessation in four countries: Direct and mediated effects from the International Tobacco Control (ITC) 4-Country Surveys.

Science.gov (United States)

Hall, Peter A; Fong, Geoffrey T; Meng, Gang

2014-07-01

Future oriented time perspective predicts a number of important health behaviors and outcomes, including smoking cessation. However, it is not known how future orientation exerts its effects on such outcomes, and no large scale cross-national studies have examined the question prospectively. The aim of the current investigation was to examine the relationship between time perspective and success in smoking cessation, and social cognitive mediators of the association. The ITC-4 is a multi-wave, four country survey (Australia, Canada, United States, United Kingdom) of current smokers (N=9772); the survey includes baseline measurements of time perspective, intentions, quit attempts, and self-reported quit status at follow-up over 8 years. We examined the predictive power of time perspective for smoking cessation, as mediated through strength of quit intentions and prior history of quit attempts. Findings indicated that those smokers with a stronger future orientation at baseline were more likely to have successfully quit at follow-up. This effect was partially explained by intention-mediated effects of future orientation on quit attempts. Future orientation predicts smoking cessation across four English-speaking countries; the cessation-facilitating effects of future orientation may be primarily due to future oriented individuals' motivated and sustained involvement in the quit cycle over time.

Alexander, J W; Kroposki, M

2001-09-01

The aims of this paper are to discuss the uses of the concept of technology from the medical science and the management perspectives; to propose a clear definition of nursing technology; and to present a study applying the use of the concept of nursing technology on nursing units. Nurse managers must use management terms correctly and the term technology may be misleading for some. A review of the nursing literature shows varied uses of the concept of technology. Thus a discussion of the dimensions, attributes, consequences, and definitions of nursing technology from the management perspective are given. A longitudinal study to measure the dimensions of nursing technology on nursing units 10 years apart. The findings suggest that the dimensions of nursing technology change over time and support the need for nurse managers to periodically assess nursing technology before making management changes at the level of the nursing unit. This study helps health care providers understand the unique role of nurses as healthcare professionals by identifying and measuring nursing technology on the nursing unit.

A European Perspective on Auditory Processing Disorder-Current Knowledge and Future Research Focus

Directory of Open Access Journals (Sweden)

Vasiliki (Vivian Iliadou

2017-11-01

Full Text Available Current notions of “hearing impairment,” as reflected in clinical audiological practice, do not acknowledge the needs of individuals who have normal hearing pure tone sensitivity but who experience auditory processing difficulties in everyday life that are indexed by reduced performance in other more sophisticated audiometric tests such as speech audiometry in noise or complex non-speech sound perception. This disorder, defined as “Auditory Processing Disorder” (APD or “Central Auditory Processing Disorder” is classified in the current tenth version of the International Classification of diseases as H93.25 and in the forthcoming beta eleventh version. APDs may have detrimental effects on the affected individual, with low esteem, anxiety, and depression, and symptoms may remain into adulthood. These disorders may interfere with learning per se and with communication, social, emotional, and academic-work aspects of life. The objective of the present paper is to define a baseline European APD consensus formulated by experienced clinicians and researchers in this specific field of human auditory science. A secondary aim is to identify issues that future research needs to address in order to further clarify the nature of APD and thus assist in optimum diagnosis and evidence-based management. This European consensus presents the main symptoms, conditions, and specific medical history elements that should lead to auditory processing evaluation. Consensus on definition of the disorder, optimum diagnostic pathway, and appropriate management are highlighted alongside a perspective on future research focus.

Egan, Paul A; van der Kooy, Frank

2013-10-01

Species of the carnivorous genus Drosera L. have long been a source of valuable natural products. The various phytochemicals characteristic of these species, particularly 1,4-naphthoquinones and flavonoids, have contributed to the diverse utilization of sundews in traditional medicine systems worldwide. A growing number of studies have sought to investigate the comparative phytochemistry of Drosera species for improved sources of pharmaceutically important compounds. The outcomes of these studies are here collated, with emergent trends discussed in detail. Important factors which affect production of secondary metabolites in plants are critically examined, such as environmental influences and in vitro culture, and recommendations subsequently presented based on this. Explicitly, the current review aims to i) present an updated, comprehensive listing of the phytochemical constituents of the genus (including quantitative data where available), ii) summarize important factors which may influence the production of phytopharmaceuticals in plants, and iii) recommend guidelines for future research based on the above, including improved standardization and quality control. We have also included a section discussing future perspectives of research on Drosera spp. based on three different research lines i) the potential to produce much needed lead compounds for treatment of tuberculosis, ii) the potential role of anthocyanins in nitrogen transport, and iii) research into 'Natural Deep Eutectic' solvents produced by Drosera spp. in the droplets or 'dew' employed to capture insect prey.

Tonn, Bruce; Healy, K.C.; Gibson, Amy; Ashish, Ashutosh; Cody, Preston; Beres, Drew; Lulla, Sam; Mazur, Jim; Ritter, A.J.

2009-01-01

This paper presents United States energy portfolios for the year 2030, developed from seven different Perspectives. The Perspectives are characterized by different weights placed on fourteen defining values (e.g., cost, social acceptance). The portfolios were constructed to achieve three primary goals, energy independence, energy security, and greenhouse gas reductions. The portfolios are also evaluated over a comprehensive set of secondary criteria (e.g., economic growth, technical feasibility). It is found that very different portfolios based on very different defining values can achieve the three primary goals. Commonalities among the portfolios include reliance upon cellulosic ethanol, nuclear power, and energy efficiency to meet year 2030 energy demands. It is concluded that the US energy portfolio must be diverse and to achieve national energy goals will require an explicit statement of goals, a strong role for government, and coordinated action across society

Cancer is a common disease that is a leading cause of death worldwide. Currently, early detection and novel therapeutic strategies are urgently needed for more effective management of cancer. Importantly, protein profiling using clinical proteomic strategies, with spectacular sensitivity and precision, offer excellent promise for the identification of potential biomarkers that would direct the development of targeted therapeutic anticancer drugs for precision medicine. In particular, clinical sample sources, including tumor tissues and body fluids (blood, feces, urine and saliva), have been widely investigated using modern high-throughput mass spectrometry-based proteomic approaches combined with bioinformatic analysis, to pursue the possibilities of precision medicine for targeted cancer therapy. Discussed in this review are the current advantages and limitations of clinical proteomics, the available strategies of clinical proteomics for the management of precision medicine, as well as the challenges and future perspectives of clinical proteomics-driven precision medicine for targeted cancer therapy.

Veltri, Stefania; Bronzetti, Giovanni; Sicoli, Graziella

2011-01-01

This article analyzes the concept of intellectual capital (IC) in the health sector sphere by studying the case of a major nonprofit research organization in this sector, which has for some time been publishing IC reports. In the last few years, health care organizations have been the object of great attention in the implementation and transfer of managerial models and tools; however, there is still a lack of attention paid to the strategic management of IC as a fundamental resource for supporting and enhancing performance improvement dynamics. The main aim of this article is to examine the IC reporting model used by the Center of Molecular Medicine (CMM), a Swedish health organization which is an outstanding benchmark in reporting its IC. We also consider the specifics of IC reporting for health organizations, the lessons learned by analyzing CMM's IC reporting, and future perspectives for research.

Developing a measure for student perspectives on institutional effectiveness in higher education

Full Text Available Orientation: This study outlines institutional effectiveness (IE in higher education (HE and interrogates its underlying elements from a student perspective. Following a review of contemporary perspectives on student educational outcomes, the study identifies and explores the importance of four pertinent indicators of IE in the context of a South African (SA higher education institution (HEI.   Research purpose: This study aimed to explore the structural validity and reliability of the Student Educational Outcomes Effectiveness Questionnaire (SEEQ, administered to students at an SA HEI, collecting data on their perceptions of IE.   Motivation for the study: Institutional effectiveness is a contested concept in HE and several approaches to define it, using various sets of underpinning elements, can be found. The conceptualisation and measuring of IE within the SA HE sector is a hugely neglected area of research. This study therefore attempted to delineate and to gauge IE, utilising the perceptions and preferences of students at an SA HEI.   Research design, approach and method: Data for this study were collected using a self-selection sample (N = 807 of students from four schools at the selected HEI. Reliability and exploratory factor analyses were performed to explore the internal consistency and structural validity of the above-mentioned SEEQ.   Main findings: The reliability of SEEQ is deemed to be acceptable and the validity of the four theoretical constructs (or dimensions hypothesised in respect of IE from a student perspective were supported.   Practical/managerial implications: Preliminary empirical evidence suggests that SEEQ could be employed in a cautious manner by HEIs (especially in SA, with a view to gauge IE, as well as to promoting the scholarship and management of institutional performance and student success.   Contribution or value-add: This article presents a multidimensional approach to the depiction and

Adding Perspective: Predicting Adolescent Sunscreen Use with an Extended Health Action Process Approach.

2016-07-01

Diseases such as skin cancer often have a very long latency period. For adolescents, especially, it may be difficult to grasp that current risk behavior is related to future health outcomes. This study examines the role of health-related time perspective (i.e. the degree to which short-term outcomes are discounted over long-time health benefits) within the Health Action Process Approach (HAPA). More specifically, based on expectancy*value theory, we tested whether time perspective interacts with self-efficacy, the central variable in this approach. A longitudinal study with three measurement points across one year assessed 156 high school students. Data were analyzed using structural equation models. While time perspective had no direct association with sunscreen use intentions, there was an interaction effect with self-efficacy; the shorter the time perspective, the smaller the association of self-efficacy with intention. Intention in turn predicted planning and sunscreen use at Time 3 (one year later). In order to maximise the impact of early onset measures for skin cancer prevention targeting the motivation for sunscreen use in adolescents, time perspective should be addressed in comprehensive sun protection interventions. © 2016 The International Association of Applied Psychology.

1984-01-01

The authors have analyzed different methods for long term energy prognoses, in particular energy consumption forecasts. Energy supply and price prognoses are also treated, but in a less detailed manner. After defining and discussing the various methods/models used in forecasts, a generalized discussion of the influence on the prognoses from the perspectives (background factors, world view, norms, ideology) of the prognosis makers is given. Some basic formal demands that should be asked from any rational forecast are formulated and discussed. The authors conclude that different forecasting methodologies are supplementing each other. There is no best method, forecasts should be accepted as views of the future from differing perspectives. The primary prognostic problem is to show the possible futures, selecting the wanted future is a question of political process.

2018-06-01

Socioemotional selectivity theory proposes that, with more limited future time perspective (FTP), the meaning of individual life goals shifts from instrumental and long-term goals, such as autonomy, to emotionally meaningful and short-term life goals, especially concerning meaningful social relationships. Adverse side effects of cancer therapy may conflict with the realization of emotionally meaningful goals leading to nonadherence. In line with the theoretical assumptions, this study aimed to investigate (a) associations among disease symptoms, physical and cognitive limitations, and FTP and (b) among FTP, family network size, striving for autonomy, and treatment adherence. One hundred fifty-seven patients (43-90 years; 75% male) with head and/or neck cancer of a German University Medical Centre completed a questionnaire measuring FTP, age, disease symptoms, physical and cognitive functioning, family network size, and treatment adherence. Autonomy was assessed with a card sort task. A structural equation model yielded an acceptable fit χ 2 (28) = 44.41, P = .025, χ 2 /df = 1.59, root mean square error of approximation = 0.06 (90% CI = 0.02, 0.09), Tucker-Lewis Index = 0.92, and Comparative Fit Index = 0.96. An increased level of disease symptoms and physical and cognitive limitations was related to a shorter subjective FTP. Furthermore, individuals with a limited FTP reported a smaller family network, a lowered quest for autonomy, and lower treatment adherence. Hypotheses derived from socioemotional selectivity theory were supported by the data. Longitudinal investigations should follow to corroborate findings and to focus on underlying mechanisms as improving patients FTP may play a crucial role in future disease management programs.

Nuclear power has made a huge contribution to the quality of life for millions, providing electrical power without emitting green house gasses to the environment. Its safety record is sterling when compared to any major industrial undertaking by any measure. Yet the much of the public and many policy makers remain skeptical of nuclear power, if not down right frightened of it or opposed to it. 'The Future of Nuclear Power' examines what must be achieved by nuclear power itself to attain public support. Dr. John Sackett, a world leader in nuclear reactor safety, examines the four areas which must be addressed as this technology moves into the future proliferation of weapons material; waste management; safety; and, economics and concludes that the key to success in each of these areas is United States leadership in determining how nuclear power is developed and applied

Expectations strongly influence future employment outcomes and social networks seem to mediate employment success of young adults with intellectual and developmental disabilities. The aim of this study is to examine the expectations of young adults with intellectual and developmental disabilities from special needs education, their parents and their school teachers regarding future work and the extent to which these expectations predict work outcome. Data on 341 young adults with intellectual or developmental disabilities, coming from special needs education, aged 17-20 years, and with an ability to work according to the Social Security Institute were examined. The school teacher's expectation was the only perspective that significantly predicted entering competitive employment, with a complementary effect of the expectation of parents and a small additional effect of the expectation of the young adult. Expectations of school teachers and parents are valuable in predicting work outcome. Therefore, it is important for professionals working with the young adult in the transition from school to work to incorporate the knowledge of school teachers and parents regarding the abilities of the young adult to enter competitive employment as a valuable source of information.

The use of albumin in the complications of cirrhosis: evidence and future perspectives

Directory of Open Access Journals (Sweden)

Alessandra Tovoli

2013-07-01

Full Text Available The therapeutic use of albumin in cirrhosis dates back to the 50s, when hypoalbuminemia was thought to play a crucial role in the pathophysiology of ascites. Today, while its efficacy in the treatment of ascites is still under investigation, it has been proved that albumin is able to improve patient outcome and survival in some specific complications of cirrhosis, such as the prevention of post-paracentesis circulatory dysfunction and the treatment of spontaneous bacterial peritonitis and hepatorenal syndrome. Beside its oncotic power, albumin carries other biological properties, the so called non-oncotic properties, including transportation and detoxification of several molecules, free radical scavenging, modulation of vascular permeability, activity on the immune system and on the haemostatic balance. Some experimental evidences indicate that not only albumin concentration but also its function is reduced in patients with cirrhosis. However, the clinical implications of such functional abnormalities is still unclear. We here present the available evidence on the use of albumin in cirrhosis and future perspectives.http://dx.doi.org/10.7175/rhc.v4i3.659

Blomgren, Anna-Sara; Svahn, Kajsa; Åström, Elisabeth; Rönnlund, Michael

2016-01-01

The authors investigated adolescents' use of coping strategies in relation to attachment to parents and time perspective. Adolescents in Grade 3 upper secondary school (M age = 18.3 years, SD = 0.6 years; n = 160) completed the Inventory of Parent and Peer Attachment, the Zimbardo Time Perspective Inventory, and the Brief COPE. Correlational analyses showed that attachment to parents was associated with a more favorable view of the past (higher past positive and lower past negative), a less fatalistic view of the present, and a more favorable view of the future (higher future positive and lower future negative). Parental attachment accounted for significant variance in composite coping scores (adaptive and maladaptive) when entered before, but not after, time perspective subscales in hierarchical regression analyses. However, time perspective (mainly present hedonistic and positive or negative future) predicted adaptive or maladaptive coping over and beyond attachment. The results are consistent with the hypothesis that most of the relationship between adolescents' attachment to parents and coping is mediated by individual differences in time perspective. By contrast, factors other than attachment to parents (e.g., temperament) must be considered to fully account for the relationship between time perspective and coping.

Perspectives on Energy Security

International Nuclear Information System (INIS)

Carlsson-Kanyama, Annika; Holmgren, Aake J.; Joensson, Thomas; Larsson, Robert L.

2007-05-01

A common notion of 'Energy Security' is that it includes access to energy resources without risking the the survival of the state. 'Security of supply' is most often the concept emphasized in the political discourse on energy security and it includes both production as well as secure and safe delivery of energy to the end consumers. Another aspect of energy security is the need for reducing energy consumption by improving energy efficiency. In this report, eight chapters covering these and other perspectives on energy security are presented. Six of the chapters deal with the supply perspective. Included topics cover power politics and geopolitical perspectives regarding large infrastructure projects and the ambitions of the EU in this regard. Further, methods and approaches for conducting risk analyses of electricity supply systems as well as for improving the security of digital control systems are discussed. As climate change will affect the supply and distribution of energy, one chapter presents an overview of this topic. The consumption perspective is discussed against the backdrop of research about household consumption practices and the role of climate change for future consumption levels. Finally, the role of armed forces as a large energy users is touched upon, as well as how so-called 'future studies' have dealt with energy as a topic

2016-01-01

With the opening up of the economy and the proliferation of mall culture, the economic relevance of impulsive buying behaviour has assumed significance. Impulsive buying behaviour is better understood by examining the impulsive buying tendency that shapes such behaviour, and since consumer behaviour differs across cultures, by incorporating an indigenous perspective in understanding and measuring the tendency. Studies were conducted to develop an Indian scale for measuring impulsive buying te...

Time perspective and environmental engagement: a meta-analysis.

Milfont, Taciano L; Wilson, Jessie; Diniz, Pollyane

2012-01-01

Environmental issues entail both a social conflict (private vs. public interests) and a temporal conflict (short- vs. long-term interests). This paper focuses on the role temporal concerns play in influencing environmental engagement by quantitatively integrating results of studies that assessed the associations between time perspective and proenvironmental attitudes and behaviors. The meta-analysis included a total of 19 independent samples and 6,301 participants from seven countries (Australia, Brazil, Germany, Mexico, New Zealand, Norway, and the United States). Results showed that the associations between time perspective and proenvironmental behaviors were higher than those for proenvironmental attitudes. Supporting predictions, the associations between future time perspective and proenvironmental behaviors were strong and nontrivial compared to those for the combined past-present time perspective. The findings indicate that future time perspective seems to play an important role in influencing individuals' attitudes and behaviors towards the environment. Implications of the findings for theory and practice are discussed.

Results from space have been unexpected and not predictable from the results of ground-based simulations. Therefore, the concept of how weightlessness and gravity modulates the regulation of body fluids must be revised and a new simulation model developed. The main questions to ask in the future...... are the following: Does weightlessness induce a diuresis and natriuresis during the initial hours of space flight leading to an extracellular and intravascular fluid volume deficit? Can sodium in excess be stored in a hitherto unknown way, particularly during space flight? Why are fluid and sodium retaining systems...

Regulatory compliance for a Yucca Mountain Repository: A performance assessment perspective

International Nuclear Information System (INIS)

Dyer, J.R.; Van Luik, A.E.; Gil, A.V.; Brocoum, S.J.

1997-01-01

The U.S. Department of Energy's Yucca Mountain Site Characterization Project is scheduled to submit a License Application in the year 2002. The License Application is to show compliance with the regulations promulgated by the U.S. Nuclear Regulatory Commission which implement standards promulgated by the U.S. Environmental Protection Agency. These standards are being revised, and it is not certain what their exact nature will be in term of either the performance measure(s) or the time frames that are to be addressed. This paper provides some insights pertaining to this regulatory history, an update on Yucca Mountain performance assessments, and a Yucca Mountain Site Characterization Project perspective on proper standards based on Project experience in performance assessment for its proposed Yucca Mountain Repository system. The Project's performance assessment based perspective on a proper standard applicable to Yucca Mountain may be summarized as follows: a proper standard should be straight forward and understandable; should be consistent with other standards and regulations; and should require a degree of proof that is scientifically supportable in a licensing setting. A proper standard should have several attributes: (1) propose a reasonable risk level as its basis, whatever the quantitative performance measure is chosen to be, (2) state a definite regulatory time frame for showing compliance with quantitative requirements, (3) explicitly recognize that the compliance calculations are not predictions of actual future risks, (4) define the biosphere to which risk needs to be calculated in such a way as to constrain potentially endless speculation about future societies and future human actions, and (5) have as its only quantitative requirement the risk limit (or surrogate performance measure keyed to risk) for the total system

Objective of this study is to provide an evidence-based analysis of the current status and future perspectives of scarless urological surgery. A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). In addition, experience with LESS and NOTES at our own institution has been considered. All clinical and investigative reports for LESS and NOTES procedures in the urological literature have been considered. A wide variety of clinical procedures in urology have been successfully completed by using LESS techniques. Thus far, experience with NOTES has largely been investigational, although early clinical reports are emerging. Further development of instrumentation and platforms is necessary for both techniques to become more widely adopted throughout the urological community.

Present and future perspectives on immunotherapy for advanced renal cell carcinoma: Going to the core or beating around the bush?

Directory of Open Access Journals (Sweden)

Hidenori Kawashima

2015-03-01

Full Text Available Metastatic lesions of renal cell carcinoma (RCC occasionally regress spontaneously after surgical removal of the primary tumor. Although this is an exceptionally rare occurrence, RCC has thus been postulated to be immunogenic. Immunotherapies, including cytokine therapy, peptide-based vaccines, and immune checkpoint inhibitors have therefore been used to treat patients with advanced, metastatic RCC. We review the history, trends, and recent progress in immunotherapy for advanced RCC and discuss future perspectives, with consideration of our experimental work on galectin 9 and PINCH as promising specific immunotherapy targets. 

Questions of time and affect: a person's affectivity profile, time perspective, and well-being.

Garcia, Danilo; Sailer, Uta; Nima, Ali Al; Archer, Trevor

2016-01-01

Background. A "balanced" time perspective has been suggested to have a positive influence on well-being: a sentimental and positive view of the past (high Past Positive), a less pessimistic attitude toward the past (low Past Negative), the desire of experiencing pleasure with slight concern for future consequences (high Present Hedonistic), a less fatalistic and hopeless view of the future (low Present Fatalistic), and the ability to find reward in achieving specific long-term goals (high Future). We used the affective profiles model (i.e., combinations of individuals' experience of high/low positive/negative affectivity) to investigate differences between individuals in time perspective dimensions and to investigate if the influence of time perspective dimensions on well-being was moderated by the individual's type of profile. Method. Participants (N = 720) answered to the Positive Affect Negative Affect Schedule, the Zimbardo Time Perspective Inventory and two measures of well-being: the Temporal Satisfaction with Life Scale and Ryff's Scales of Psychological Well-Being-short version. A Multivariate Analysis of Variance (MANOVA) was conducted to identify differences in time perspective dimensions and well-being among individuals with distinct affective profiles. Four structural equation models (SEM) were used to investigate which time perspective dimensions predicted well-being for individuals in each profile. Results. Comparisons between individuals at the extreme of the affective profiles model suggested that individuals with a self-fulfilling profile (high positive/low negative affect) were characterized by a "balanced" time perspective and higher well-being compared to individuals with a self-destructive profile (low positive/high negative affect). However, a different pattern emerged when individuals who differed in one affect dimension but matched in the other were compared to each other. For instance, decreases in the past negative time perspective

The present experiment aimed to investigate the differences in time perception and time perspective between subjects representing two developmental stages, namely adolescence and middle adulthood. Twenty Chinese adolescents aged 15-25 and twenty Chinese adults aged 35-55 participated in the study. A time discrimination task and a time reproduction task were implemented to measure the accuracy of their time perception. The Zimbardo Time Perspective Inventory (Short-Form) was adopted to assess their time orientation. It was found that adolescents performed better than adults in both the time discrimination task and the time reproduction task. Adolescents were able to differentiate different time intervals with greater accuracy and reproduce the target duration more precisely. For the time reproduction task, it was also found that adults tended to overestimate the duration of the target stimuli while adolescents were more likely to underestimate it. As regards time perspective, adults were more future-oriented than adolescents, whereas adolescents were more present-oriented than adults. No significant relationship was found between time perspective and time perception. Copyright © 2014 Elsevier B.V. All rights reserved.

In the rapidly growing economies of Asia and Oceania, food security has become a primary concern. With the rising population, growing more food at affordable prices is becoming even more important. In addition, the predicted climate change will lead to drastic changes in global surface temperature and changes in rainfall patterns that in turn would pose a serious threat to plant vegetation worldwide. As a result, understanding how plants will survive in a changing climate will be increasingly important. Such challenges require integrated approaches to increase agricultural production and cope with environmental threats. Proteomics can play a role in unravel the underlying mechanisms for food production to address the growing demand for food. In this review, the current status of food crop proteomics is discussed, especially in regards to the Asia and Oceania regions. Furthermore, the future perspective in relation to proteomic techniques for the important food crops is highlighted.

Saleem, Muhammad

2013-01-01

A biosensor is an analytical device which can be used to convert the existence of a molecule or compound into a measurable and useful signal. Biosensors use stimulus to translate changes to recognisable signals and have great importance to society. Applications include diagnosis tools for diseases, security appliances, and other biomedical equipments. Biosensors can also be used in the detection of pathogens and other microbes in foodstuffs, drugs and processing industries. Enormous progress and advancement has been witnessed in this area. Research and development in micro level systems serves to interface biology with novel materials such as nanomaterial. Development of high speed and accurate electronic devices tfor use in medicine and energy storage (such as biofuel cells) is one of the target areas. This paper discusses the importance, use and current and future trend in the application of biosensors

Conceptualizing and Measuring the Quality of Democracy: The Citizens’ Perspective

Directory of Open Access Journals (Sweden)

Dieter Fuchs

2018-03-01

Full Text Available In recent years, several measurements of the quality of democracy have been developed (e.g. Democracy Barometer, Varieties of Democracy Project. These objective measurements focus on institutional and procedural characteristics of democracy. This article starts from the premise that in order to fully understand the quality of democracy such objective measurements have to be complemented by subjective measurements based on the perspective of citizens. The aim of the article is to conceptualize and measure the subjective quality of democracy. First, a conceptualization of the subjective quality of democracy is developed consisting of citizens’ support for three normative models of democracy (electoral, liberal, and direct democracy. Second, based on the World Values Survey 2005–2007, an instrument measuring these different dimensions of the subjective quality of democracy is suggested. Third, distributions for different models of democracy are presented for some European and non-European liberal democracies. They reveal significant differences regarding the subjective quality of democracies. Fourth, the subjective quality of democracy of these countries is compared with the objective quality of democracy based on three indices (electoral democracy, liberal democracy and direct popular vote developed by the Varieties of Democracy (V-Dem Project. Finally, further research questions are discussed.

Reasons for low participation of ethnic minorities in genetic studies are multifactorial and often poorly understood. Based on published literature, participation in genetic testing is low among Black African immigrants/refugees although they are purported to bear disproportionate disease burden. Thus, research involving Black African immigrant/refugee populations that examine their perspectives on participating in genetic studies is needed. This report examines and describes the knowledge of medical genetics, group-based medical mistrust, and future expectations of genetic research and the influence of these measures on the perceived disadvantages of genetic testing among Black African immigrants/refugees. Using a cross-sectional survey design, a nonprobability sample (n = 212) of Black African immigrants/refugees was administered a questionnaire. Participants ranged in age from 18 to 61 years (mean = 38.91, SD = 9.78). The questionnaire consisted of 5 instruments: (a) sociodemographic characteristics, (b) Knowledge of Medical Genetics scale, (c) Group-Based Medical Mistrust Scale, (d) Future Expectations/Anticipated Consequences of Genetics Research scale, and (e) Perceived Disadvantages of Genetic Testing scale. Participants were concerned that genetic research may result in scientists 'playing God,' interfering with the natural order of life. In multivariate analyses, the perceived disadvantages of genetic testing increased as medical mistrust and anticipated negative impacts of genetic testing increased. Increase in genetic knowledge contributed to a decrease in perceived disadvantages. Our findings suggest that recruitment of Black African immigrants/refugees in genetic studies should address potential low knowledge of genetics, concerns about medical mistrust, the expectations/anticipated consequences of genetic research, and the perceived disadvantages of genetic testing.

Shaller, Dale

2004-01-01

The objective of this study was to identify issues, obstacles, and priorities related to implementing and using child health care quality measures from the perspectives of 4 groups: 1) funders of quality-measurement development and implementation; 2) developers of quality measures; 3) users of quality measures (including Medicaid and the State Children's Health Insurance Program, employer coalitions, and consumer groups); and 4) health plans and providers (in their role as both subjects and users of quality measures). A series of semistructured interviews was conducted with approximately 40 opinion leaders drawn from these 4 groups. The interviews were conducted by telephone between September and December of 2001. Major topic areas covered in the interviews were similar across the groups. Topic areas included 1) strategic vision and/or objectives for funding, developing, or using quality measures for children's health care; 2) a brief summary of the specific quality measures funded, developed, or used; 3) issues and challenges facing funders and developers of measures; 4) major successes achieved; 5) obstacles to implementation and use of measures; and 6) priority needs for future funding. Leaders from all 4 groups acknowledge the importance of developing a robust set of quality measures that can serve multiple objectives and multiple audiences. Standardization of measures is viewed as a critical feature related to all objectives. An assessment of specific quality measures funded, developed, or used by strategic objective shows a high correlation between the uses intended by funders and developers and the actual applications of the various users. The most commonly cited measures across all groups are the Consumer Assessment of Health Plans Survey and Health Plan Employer Data and Information Set, followed by the Child and Adolescent Health Measurement Initiative and special topic studies to support quality-improvement applications (eg, asthma, diabetes, etc).

Environmental change is monitored in North America through repeated measurements of weather, stream and river flow, air and water quality, and most recently, soil properties. Some skepticism remains, however, about whether repeated soil sampling can effectively distinguish between temporal and spatial variability, and efforts to document soil change in forest ecosystems through repeated measurements are largely nascent and uncoordinated. In eastern North America, repeated soil sampling has begun to provide valuable information on environmental problems such as air pollution. This review synthesizes the current state of the science to further the development and use of soil resampling as an integral method for recording and understanding environmental change in forested settings. The origins of soil resampling reach back to the 19th century in England and Russia. The concepts and methodologies involved in forest soil resampling are reviewed and evaluated through a discussion of how temporal and spatial variability can be addressed with a variety of sampling approaches. Key resampling studies demonstrate the type of results that can be obtained through differing approaches. Ongoing, large-scale issues such as recovery from acidification, long-term N deposition, C sequestration, effects of climate change, impacts from invasive species, and the increasing intensification of soil management all warrant the use of soil resampling as an essential tool for environmental monitoring and assessment. Furthermore, with better awareness of the value of soil resampling, studies can be designed with a long-term perspective so that information can be efficiently obtained well into the future to address problems that have not yet surfaced.

Role of gamma knife radiosurgery in neurosurgery. Past and future perspectives

International Nuclear Information System (INIS)

Koga, Tomoyuki; Shin, Masahiro; Saito, Nobuhito

2010-01-01

The gamma knife was the first radiosurgical device developed at the Karolinska Institute in 1967. Stereotactic radiosurgery using the gamma knife has been widely accepted in clinical practice and has contributed to the development of neurosurgery. More than 500,000 patients have been treated by gamma knife stereotactic radiosurgery so far, and the method is now an indispensable neurosurgical tool. Here we review long-term outcomes and development of stereotactic radiosurgery using the gamma knife and discuss its future perspectives. The primary role of stereotactic radiosurgery is to control small well-demarcated lesions such as metastatic brain tumors, meningiomas, schwannomas, and pituitary adenomas while preserving the function of surrounding brain tissue. The gamma knife has been used as a primary treatment or in combination with surgery, and some applications have been accepted as standard treatment in the field of neurosurgery. Treatment of cerebral arteriovenous malformations has also been drastically changed after emergence of this technology. Controlling functional disorders is another role of stereotactic radiosurgery. There is a risk of radiation-induced adverse events, which are usually mild and less frequent. However, especially in large or invasive lesions, those risks are not negligible and pose limitations. Advancement of irradiation technology and dose planning software have enabled more sophisticated and safer treatment, and further progress will contribute to better treatment outcomes not only for brain lesions but also for cervical lesions with less invasive treatment.

Helium Energetic Neutral Atoms from the Heliosphere: Perspectives for Future Observations

Observations of energetic neutral atoms (ENAs) allow for remote sensing of plasma properties in distant regions of the heliosphere. So far, most of the observations have concerned only hydrogen atoms. In this paper, we present perspectives for observations of helium energetic neutral atoms (He ENAs). We calculated the expected intensities of He ENAs created by the neutralization of helium ions in the inner heliosheath and through the secondary ENA mechanism in the outer heliosheath. We found that the dominant source region for He ENAs is the inner heliosheath. The obtained magnitudes of intensity spectra suggest that He ENAs can be observed with future ENA detectors, as those planned on Interstellar Mapping and Acceleration Probe . Observing He ENAs is most likely for energies from a few to a few tens of keV/nuc. Estimates of the expected count rates show that the ratio of helium to hydrogen atoms registered in the detectors can be as low as 1:10{sup 4}. Consequently, the detectors need to be equipped with an appropriate mass spectrometer capability, allowing for recognition of chemical elements. Due to the long mean free paths of helium ions in the inner heliosheath, He ENAs are produced also in the distant heliospheric tail. This implies that observations of He ENAs can resolve its structure, which seems challenging from observations of hydrogen ENAs since energetic protons are neutralized before they progress deeper in the heliospheric tail.

Family Resiliency: A Neglected Perspective in Addressing Obesity in Young Children.

Science.gov (United States)

Sigman-Grant, Madeleine; Hayes, Jenna; VanBrackle, Angela; Fiese, Barbara

2015-12-01

Traditional research primarily details child obesity from a risk perspective. Risk factors are disproportionately higher in children raised in poverty, thus negatively influencing the weight status of low-income children. Borrowing from the field of family studies, the concept of family resiliency might provide a unique perspective for discussions regarding childhood obesity, by helping to identify mediating or moderating protective mechanisms that are present within the family context. A thorough literature review focusing on (1) components of family resiliency that could be related to childhood obesity and (2) factors implicated in childhood obesity beyond those related to energy balance was conducted. We then conceptualized our perspective that understanding resiliency within an obesogenic environment is warranted. Both family resiliency and childhood obesity prevention rely on the assumptions that (1) no one single answer can address the multifactorial nature involved with adopting healthy lifestyle behaviors and (2) the pieces in this complex puzzle will differ between families. Yet, there are limited holistic studies connecting family resiliency measures and childhood obesity prevention. Combining mixed methodology using traditional measures (such as general parenting styles, feeding styles, and parent feeding behaviors) with potential family resiliency measures (such as family routines, family stress, family functioning, and family structure) might serve to broaden understanding of protective strategies. The key to future success in child obesity prevention and treatment may be found in the application of the resiliency framework to the exploration of childhood obesity from a protective perspective focusing on the family context.

Participants (N = 720) answered to the Positive Affect Negative Affect Schedule, the Zimbardo Time Perspective Inventory and two measures of well-being: the Temporal Satisfaction with Life Scale and Ryff’s Scales of Psychological Well-Being-short version. A Multivariate Analysis of Variance (MANOVA) was conducted to identify differences in time perspective dimensions and well-being among individuals with distinct affective profiles. Four structural equation models (SEM) were used to investigate which time perspective dimensions predicted well-being for individuals in each profile. Results. Comparisons between individuals at the extreme of the affective profiles model suggested that individuals with a self-fulfilling profile (high positive/low negative affect) were characterized by a “balanced” time perspective and higher well-being compared to individuals with a self-destructive profile (low positive/high negative affect). However, a different pattern emerged when individuals who differed in one affect dimension but matched in the other were compared to each other. For instance, decreases in the past negative time

2001-01-01

The RIKEN-BNL Research Center workshop on ''Future Transversity Measurements'' was held at BNL from September 18-20, 2000. The main goal of the workshop was to explore future measurements of transversity distributions. This issue is of importance to the RHIC experiments, which will study polarized proton-proton collisions with great precision. One of the workshop's goals was to enhance interactions between the DIS community at HERA and the spin community at RHIC in this field. The workshop has been well received by the participants; the number of 69 registered participants demonstrates broad interest in the workshop's topics. The program contained 35 talks and there was ample time for lively discussions. The program covered all recent work in the field and in addition some very elucidating educational talks were given. At the workshop the present status of the field was discussed and it has succeeded in stimulating new experimental and theoretical studies (e.g. model calculations for interference fragmentation functions (IFF), IFF analysis at DELPHI). It also functioned to focus attention on the open questions that need to be resolved for near future experiments. In general, the conclusions were optimistic, i.e. measuring the transversity functions seems to be possible, although some new experimental hurdles will have to be taken

Essential severe accident mitigation measures for operating and future PWR's

Severe Accident mitigation measures are a constituent of the safety concept in Europe not only for operating but also for future light water reactors. While operating reactors mainly have been backfitted with such measure, for future reactors Severe Accident mitigation measures already have to be considered in the design phase. Severe Accident measures are considered as the 4{sup th} level of defense for future reactors. This difference has consequences also on the kind of measures proposed to be introduced. While in operating plants Severe Accident mitigation measures are considered for further risk reduction, in future reactors an explicit higher level of safety is required resulting in additional design measures. This higher safety level is expressed in the requirement that there must be no need for evacuation of surrounding populations except in the immediate vicinity of the plant and for long-term restrictions with regard to the consumption of locally grown food. Because of the potential hazard posed by radioactive releases to the environment in the event of an Severe Accident situation depends largely on the airborne material in the containment atmosphere and on the containment integrity, new system features to prevent loss of containment integrity have been introduced in the design of the NPP's. For these tasks it has been necessary to develop and qualify new system technologies and implement them finally into NPP's, e.g. like systems for containment atmosphere H{sub 2}-control, filtered venting, core retention devices and atmosphere sampling. The following systems are introduced for operating as well as for future plants: {center_dot} The Hydrogen Control System is based on the Passive Autocatalytic Recombiner (PAR) technology. There is no need for any operator actions because of the self-starting feature of the catalyst if hydrogen is released. {center_dot} In situ Post Accident Sampling System (In situ-PASS) are introduced for the purpose of

[The future of vocational rehabilitation--vocational rehabilitation for the future. An explanation with the federal government's austerity measures].

Science.gov (United States)

Wittwer, U

1997-02-01

Under the law on enhancing growth and employment (Wachstums- und Beschäftigungsförderungsgesetz-WFG), the legal entitlement to vocational rehabilitation hitherto stipulated in the employment promotion act (Arbeitsförderungsgesetz-AFG), has been restricted to a narrowly defined population; and pension insurance scheme spending in the entire rehabilitation field been "capped" to the 1993 level minus some 600 million DM. Moreover, the transitional allowance applicable for pension insurance rehabilitees will be lowered. In addition, economies amounting to some 500 million DM have been imposed on the federal employment service Bundesanstalt für Arbeit. These measures are placing persons with disability at a disadvantage, accept exclusion of entire groups of disabled persons, and endanger the very existence of numerous rehabilitation facilities previously established with significant amounts of public funding. A blind eye is being turned on the high level of demand for qualification measures, on the overall economic benefits of rehabilitation measures, and on the fact that measures of this kind are disabled persons' only chance to hold their own in the face of labour market competitiveness. Also, poor awareness seems to exist of the fact that, in the longer run, meaningful contributions to greater economy will more likely be generated by structural adjustment, increased effectiveness, and greater flexibility. The future of vocational rehabilitation is being placed at risk--notwithstanding that vocational rehabilitation for the future is imperative.

Kunzmann, Ute; Nowak, Jana; Thomas, Stefanie; Nestler, Steffen

2017-12-18

There has been mixed evidence for age differences in wisdom-related knowledge across the adult life span. This study investigated two potential moderators of the link between age and wisdom-related knowledge: the wisdom criteria and the wisdom tasks. To test these moderators, 40 younger and 40 older participants completed four wisdom tasks differing in context-richness. Independent trained raters coded the resulting think-aloud protocols in terms of value relativism, as defined in the Berlin wisdom paradigm, and perspective taking, as defined by Grossmann. The type of task did not show any main or interaction effects on the present two wisdom criteria. However, age differences in the two wisdom criteria were multidirectional: whereas perspective taking did not differ by age group, value relativism was lower in older than younger adults. In addition, value relativism, but not perspective taking, was related to measures of fluid and crystallized intelligence, whereas perspective taking, but not value relativism, was related to a measure of life investment. This study provides evidence for the idea that value relativism and perspective taking are two distinct facets of wisdom-related knowledge. Implications for future age-comparative research interested in wisdom are discussed. © The Author(s) 2017. Published by Oxford University Press on behalf of The Gerontological Society of America.

Emphasis will be put on the experimental installations addressing nuclear physics with relevance for astrophysics. (author)

Future HEP Accelerators: The US Perspective

Energy Technology Data Exchange (ETDEWEB)

Bhat, Pushpalatha [Fermilab; Shiltsev, Vladimir [Fermilab

2015-11-02

Accelerator technology has advanced tremendously since the introduction of accelerators in the 1930s, and particle accelerators have become indispensable instruments in high energy physics (HEP) research to probe Nature at smaller and smaller distances. At present, accelerator facilities can be classified into Energy Frontier colliders that enable direct discoveries and studies of high mass scale particles and Intensity Frontier accelerators for exploration of extremely rare processes, usually at relatively low energies. The near term strategies of the global energy frontier particle physics community are centered on fully exploiting the physics potential of the Large Hadron Collider (LHC) at CERN through its high-luminosity upgrade (HL-LHC), while the intensity frontier HEP research is focused on studies of neutrinos at the MW-scale beam power accelerator facilities, such as Fermilab Main Injector with the planned PIP-II SRF linac project. A number of next generation accelerator facilities have been proposed and are currently under consideration for the medium- and long-term future programs of accelerator-based HEP research. In this paper, we briefly review the post-LHC energy frontier options, both for lepton and hadron colliders in various regions of the world, as well as possible future intensity frontier accelerator facilities.

In the face of escalating spending, measuring and maximizing the value of health services has become an important focus of health reform. Recent initiatives aim to incentivize high-value care through provider and hospital payment reform, but the role of the emergency department (ED) remains poorly defined. To achieve an improved understanding of the value of emergency care, we have developed a framework that incorporates the perspectives of stakeholders in the delivery of health services. A pragmatic review of the literature informed the design of this framework to standardize the definition of value in emergency care and discuss outcomes and costs from different stakeholder perspectives. The viewpoint of patient, provider, payer, health system, and society is each used to assess value for emergency medical conditions. We found that the value attributed to emergency care differs substantially by stakeholder perspective. Potential targets to improve ED value may be aimed at improving outcomes or controlling costs, depending on the acuity of the clinical condition. The value of emergency care varies by perspective, and a better understanding is achieved when specific outcomes and costs can be identified, quantified, and measured. Using this framework can help stakeholders find common ground to prioritize which costs and outcomes to target for research, quality improvement efforts, and future health policy impacting emergency care.

A Review of Visual Perspective taking in Autism Spectrum Disorder

Directory of Open Access Journals (Sweden)

Amy ePearson

2013-10-01

Full Text Available Impairments in social cognition are a key symptom of Autism Spectrum Disorder. People with autism have great difficulty with understanding the beliefs and desires of other people. In recent years literature has begun to examine the link between impairments in social cognition and abilities which demand the use of spatial and social skills, such as visual perspective taking (VPT. Flavell (1977 defined two levels of perspective taking: VPT level 1 is the ability to understand that other people have a different line of sight to ourselves, whereas VPT level 2 is the understanding that two people viewing the same item from different points in space may see different things. So far, literature on whether either level of VPT is impaired or intact in autism is inconsistent. Here we review studies which have examined VPT levels 1 and 2 in people with autism with a focus on the methods that have been used to measure perspective taking. We conclude the review with an evaluation of the findings into VPT in autism and give recommendations for future research which may give a clearer insight into whether perspective taking is truly impaired in autism.

Time Perspective and Age: A Review of Age Associated Differences.

Laureiro-Martinez, Daniella; Trujillo, Carlos A; Unda, Juliana

2017-01-01

We investigate the relationship between age and the five dimensions of time perspective measured by the Zimbardo Time Perspective Inventory (ZTPI) (past negative, past positive, present hedonistic, present fatalistic, and future). Time perspective is related to well-being, decision-making, level of development, and many other psychological issues. Hence, the existence of a systematic relationship between time perspective and age should be considered in all studies for which time is a relevant variable. However, no specific research about this has been conducted. We collected 407 papers that referenced the ZTPI between 2001 and 2015. From those, 72 studies met our inclusion criteria. They included 29,815 participants from 19 countries whose age spans most phases of adulthood (from 13.5 to 75.5 years, mean 28.7). We analyzed these studies adapting meta-analytical techniques. We found that present hedonistic and past negative dimensions are negatively related to aging with partial eta squared effect sizes of roughly 0.15. Our results have implications for the design of studies related to time as our findings highlight the importance of taking into account the differences associated with age.

Both because of the large number of women undergoing surgery and a high cure rates, psychological rehabilitation of the consequences of breast cancer and side effects of their treatment is a major challenge of modern psychooncology. Aim. The study analyzed the quality of life in women with breast cancer, with particular emphasis on indicators of sexual satisfaction, future perspectives and body image, depending on the method of surgery. The study included 42 women aged 35-70 years, 3 months after surgery due to early breast cancer, treated with adjuvant chemotherapy. The following research tools were used in the study: two EORTC questionnaires: QLQ-C30, BR23, and sexual function questionnaire: PL-FSFI. There was no significant difference in the overall quality of life, depending on the type of surgery. The greatest local complaints were reported by patients after breast conserving surgery (BCT) with axillary lymphadenectomy. A higher level of cognitive functioning but a greater severity of systemic side effects was found in women undergoing mastectomy compared to BCT-patients. Women who underwent surgery of the right breast reported increased problems in sexual functioning (p = 0.034). Multiple regression analysis showed a positive correlation of the emotional functioning variable with the assessment of future perspectives (p = 0.01) and body image (p = 0.007). The type of surgical technique does not affect the overall quality of life and sexual satisfaction. Problems with memory and attention do not correlate directly with the side effects, and as such require an independent diagnostics. Women undergoing treatment of the dominant-side breast should be the candidates for sexology consultation. There is a risk of disturbances in the body image and in the assessment of future perspectives in patients with emotional disorders observed within 3 months after surgery.

Despite the centrality of time to the aging process, the well-being consequences of different temporal orientations for optimal aging are poorly understood. We investigate one underexamined area of temporal orientation, namely a balanced time perspective, in a large, lifespan sample from the Netherlands. Participants consisted of 512 Dutch adults ranging in age from 17 to 92 years (Mage = 46.46, SD = 21.37), including 186 male and 326 females. Participants completed a measure of balanced time perspective, mental health, and wisdom. RESULTS indicated that a balanced time perspective uniquely predicted both mental health and wisdom even after controlling for demographic, physical health, and personality variables. Younger adults tended to be more future-oriented relative to older adults while older adults tended to be more past-oriented relative to younger adults. Further, both midlife and younger adults were more likely to have a balanced time perspective relative to older adults. A balanced time perspective is associated with higher well-being and wisdom across the adult age span.

Neuroscience in the residency curriculum: the psychoanalytic psychotherapy perspective.

Watson, Brendon O; Michels, Robert

2014-04-01

Educators of future psychiatrists tend to teach an array of approaches to the mind and brain, including among them the neurobiologic perspective and the psychoanalytic perspective. These may be considered at opposite ends of many spectra, including the fact that psychoanalysis takes a large-scale and treatment-oriented perspective and has helped countless patients over the years, while neuroscience has tended to be reductionistic, focused on understanding, and has helped very few people. A tension, therefore, exists for the educator in teaching neuroscience: is it wise to spend valuable time and energy teaching this interesting but, thus far, impractical field to future practitioners? Here, we argue that neuroscience is re-orienting itself towards more psychoanalytically relevant questions and is likely, in future years, to give new insights into the nature of basic drives and social relations. We additionally argue for balance on the part of providers in both acknowledging biologic underpinnings for clinical phenomena and yet continuing to take a stance oriented towards appropriate change. Given the burgeoning new focus within neuroscience on topics directly relating to the human internal experience and the novel challenges in both understanding those advances and appropriately using them, we encourage educators to continue to give future psychiatrists the educational foundation they need to follow neuroscientific discoveries into the future.

Therefore, it describes in detail the process of creating the reduced Basque version of the CDS scale (Children's Depression Scale; Lang and Tisher, 1978, which measures depression in children and adolescents. In a first study, the items that make up the reduced version of the CDS (CDS-R are selected from a set of analysis conducted on a sample of 886 children and adolescents who were administered the extensive version of the CDS adapted to the Basque language (Balluerka, Gorostiaga, and Haranburu, 2012. Subsequently, the CDS-R is validated on a sample of 2,165 participants. This second study examines the factorial structure, the internal consistency and the temporal stability of the instrument, as well as the relationship between its dimensions and gender, academic performance, emotional intelligence and attachment. Thus, evidence is obtained on the reliability and validity of the reduced version of the instrument, which guarantees suitable evaluation of the construct the instrument is intended to measure.

The Renewable Electricity Futures Study (RE Futures) provides an analysis of the grid integration opportunities, challenges, and implications of high levels of renewable electricity generation for the U.S. electric system. The study is not a market or policy assessment. Rather, RE Futures examines renewable energy resources and many technical issues related to the operability of the U.S. electricity grid, and provides initial answers to important questions about the integration of high penetrations of renewable electricity technologies from a national perspective. RE Futures results indicate that a future U.S. electricity system that is largely powered by renewable sources is possible and that further work is warranted to investigate this clean generation pathway.

The connection of time perspective with personality traits and subjective well-being

Full Text Available The aim of our study was to research the connection of the six time perspective dimensions and of balanced time perspective with personality traits and subjective well-being. Our starting point was the assumption that time perspective is closely connected to personality traits and subjective well-being. It has been theorized that so called balanced time perspective is optimal in the Western cultures. It is defined by moderately high scores on present-hedonistic and future, high scores on past-positive and low scores on past-negative and present-fatalistic, with an emphasis on individual's ability of flexible adjusting in given situations. People with balanced time perspective profile have many positive memories of the past, find enough opportunity for relaxation and pleasure in the present, and seek new challenges in the future, which gives them motivation for hard work. They are supposed to handle daily life more efficiently and to be happier than people with other time perspective profiles. Therefore we have hypothesized positive connection of balanced time perspective with positive personality traits and high scores on subjective well-being. 279 students studying different subjects at the Faculty of arts, University in Ljubljana, whose mean age was 21.2 years, participated in the study. The results reveal connections of positive time perspective dimensions (including transcendental-future and of balanced time perspective with extraversion, agreeableness, conscientiousness and higher level of subjective well-being, and connections of negative time perspective dimensions with neuroticism, lower level of subjective well-being and higher level of depression. It turned out that balance of time perspective is an important predictor of individual's level of satisfaction with life, and it also explains some variance in positive emotionality and depression.

Value of information analysis from a societal perspective: a case study in prevention of major depression.

Productivity losses usually have a considerable impact on cost-effectiveness estimates while their estimated values are often relatively uncertain. Therefore, parameters related to these indirect costs play a role in setting priorities for future research from a societal perspective. Until now, however, value of information analyses have usually applied a health care perspective for economic evaluations. Hence, the effect of productivity losses has rarely been investigated in such analyses. The aim of the current study therefore was to investigate the effects of including or excluding productivity costs in value of information analyses. Expected value of information analysis (EVPI) was performed in cost-effectiveness evaluation of prevention from both societal and health care perspectives, to give us the opportunity to compare different perspectives. Priorities for future research were determined by partial EVPI. The program to prevent major depression in patients with subthreshold depression was opportunistic screening followed by minimal contact psychotherapy. The EVPI indicated that regardless of perspective, further research is potentially worthwhile. Partial EVPI results underlined the importance of productivity losses when a societal perspective was considered. Furthermore, priority setting for future research differed according to perspective. The results illustrated that advise for future research will differ for a health care versus a societal perspective and hence the value of information analysis should be adjusted to the perspective that is relevant for the decision makers involved. The outcomes underlined the need for carefully choosing the suitable perspective for the decision problem at hand.

This study investigated the joint effect of message framing and time perspective in adherence-promoting communication targeting patients with chronic diseases. Based on previous framing and time perspective research, it was hypothesized that the gain frame would show an advantage over the loss frame among future-oriented patients; for present-oriented patients, it was hypothesized that the framing effect would be relatively indistinct. In total, 1,108 currently nonadherent patients with chronic disease participated in an experiment where they were randomly assigned to either gain- or loss-framed messages addressing key beliefs underlying their nonadherence or a no-message control condition. Intention and attitude regarding future adherence as well as message perceptions were measured after message presentation. Results of this study generally supported the hypotheses. Message topics-whether the messages addressed patients' perceived need for medications or concerns about side effects-did not moderate the effect of framing or the interaction between framing and time perspective. Theoretical and practical implications are discussed.

This study investigated the role of present and future time perspectives, and their relationships with subjective norms and beliefs regarding violence, in predicting violent behaviors among urban middle school students in the Midwestern United States. Although present time perspective covaried with subjective norms and beliefs, each made a unique prediction of self-reported violent behaviors. Future time perspective was not a significant predictor when accounting for these relationships. In addition, present orientation moderated the relationship between subjective norms and beliefs and rates of violent behaviors; those with higher present orientations exhibited stronger associations. We replicated this pattern of results in data from new participants in a subsequent wave of the study. Interventions that explicitly address issues related to time perspective may be effective in reducing early adolescent violence.

Full Text Available The aim of this paper is to describe and discuss some perspectives on definitions, constructs and outcome parameters of physical behaviour. The paper focuses on the following constructs: Physical activity & active lifestyle vs. sedentary behaviour & sedentary lifestyle; Amount of physical activity vs. amount of walking; Detailed body posture & movement data vs. overall physical activity data; Behavioural context of activities; Quantity vs. quality; Physical behaviour vs. physiological response.Subsequently, the following outcome parameters provided by data reduction procedures are discussed: Distribution of length of bouts; Variability in bout length; Time window; Intensity and intensity threshold.The overview indicates that physical behaviour is a multi-dimensional construct, and it stresses the importance and relevance of constructs and parameters other than total amount of physical activity.It is concluded that the challenge for the future will be to determine which parameters are most relevant, valid and responsive. This is a matter for physical behaviour researchers to consider, that is critical to multi-disciplinary collaboration.

Cross-sectional survey. To examine caregivers' perspectives on the effectiveness of rehabilitative support experienced by youth with spinal cord injury (SCI) during acute rehabilitation and after community reintegration in terms of their community participation. Data collection took place at the three Shriners SCI hospitals: Chicago, Philadelphia, and Northern California. A total of 132 primary caregivers of youth with SCI completed a survey on what their child had experienced during and after rehabilitation to enhance their community participation. Caregivers found technical support from staff (41%), motivation and encouragement from staff (25%), and education (17%) to be the most important factors during rehabilitation for encouraging their child's future participation in school or community activities. Caregivers found involvement in activities (30%), personal resilience (22%) and interactions with others with disabilities (13%) to be important experiences since rehabilitation in terms of their child's participation in school and community activities. Caregivers who responded that something they experienced during rehabilitation was helpful to participation had children who had been injured longer and who were older at time of injury. In addition, caregivers who reported that something they have experienced since their child's rehabilitation has been helpful in terms of participation also had children who were older at time of injury. Findings from this study can be used to help professionals tailor rehabilitation programs to better meet the needs of youth with SCI and their families, thereby increasing chances of successful reintegration back into their communities.

Proton electromagnetic form factors: present status and future perspectives at PANDA

Directory of Open Access Journals (Sweden)

Tomasi-Gustafsson E.

2015-01-01

Full Text Available Data and models on electromagnetic proton form factors are reviewed, highlighting the contribution foreseen by the PANDA collaboration. Electromagnetic hadron form factors contain essential information on the internal structure of hadrons. Precise and surprising data have been obtained at electron accelerators, applying the polarization method in electron-proton elastic scattering. At electron-positron colliders, using initial state radiation, BABAR measured proton time-like form factors in a wide time-like kinematical region and the BESIII collaboration will measure very precisely proton and neutron form factors in the threshold region. In the next future an antiproton beam with momentum up to 15 GeV/c will be available at FAIR (Darmstadt. Measurements of the reaction p̅ + p → e+ + e− by the PANDA collaboration will contribute to the individual determination of electric and magnetic form factors in the time-like region of momentum transfer squared, as well as to their first determination in the unphysical region (below the kinematical threshold, through the reaction p̅ + p → e+ + e− + π0. From the discussion on feasibility studies at PANDA, we focus on the consequences of such measurements in view of an unified description of form factors in the full kinematical region. We present models which have the necessary analytical requirements and apply to the data in the whole kinematical region.

Clustering Measurements of broad-line AGNs: Review and Future

Directory of Open Access Journals (Sweden)

Mirko Krumpe

2014-12-01

Full Text Available Despite substantial effort, the precise physical processes that lead to the growth of super-massive black holes in the centers of galaxies are still not well understood. These phases of black hole growth are thought to be of key importance in understanding galaxy evolution. Forthcoming missions such as eROSITA, HETDEX, eBOSS, BigBOSS, LSST, and Pan-STARRS will compile by far the largest ever Active Galactic Nuclei (AGNs catalogs which will allow us to measure the spatial distribution of AGNs in the universe with unprecedented accuracy. For the first time, AGN clustering measurements will reach a level of precision that will not only allow for an alternative approach to answering open questions in AGN and galaxy co-evolution but will open a new frontier, allowing us to precisely determine cosmological parameters. This paper reviews large-scale clustering measurements of broad line AGNs. We summarize how clustering is measured and which constraints can be derived from AGN clustering measurements, we discuss recent developments, and we briefly describe future projects that will deliver extremely large AGN samples which will enable AGN clustering measurements of unprecedented accuracy. In order to maximize the scientific return on the research fields of AGN and galaxy evolution and cosmology, we advise that the community develops a full understanding of the systematic uncertainties which will, in contrast to today’s measurement, be the dominant source of uncertainty.

Temporal orientation refers to individual differences in the relative emphasis one places on the past, present, or future, and it is related to academic, financial, and health outcomes. We propose and evaluate a method for automatically measuring temporal orientation through language expressed on social media. Judges rated the temporal orientation of 4,302 social media messages. We trained a classifier based on these ratings, which could accurately predict the temporal orientation of new messages in a separate validation set (accuracy/mean sensitivity = .72; mean specificity = .77). We used the classifier to automatically classify 1.3 million messages written by 5,372 participants (50% female; ages 13-48). Finally, we tested whether individual differences in past, present, and future orientation differentially related to gender, age, Big Five personality, satisfaction with life, and depressive symptoms. Temporal orientations exhibit several expected correlations with age, gender, and Big Five personality. More future-oriented people were older, more likely to be female, more conscientious, less impulsive, less depressed, and more satisfied with life; present orientation showed the opposite pattern. Language-based assessments can complement and extend existing measures of temporal orientation, providing an alternative approach and additional insights into language and personality relationships. © 2015 Wiley Periodicals, Inc.

Time under control: time perspective and desire for control in substance use.

2010-08-01

To investigate the role of time perspective and desire for control in self-reported substance use and to test for a moderating effect of desire for control in the relation between time perspective and substance use. A random sample of 240 persons, aged 15 years and over, selected in various public spaces in an urban region in central France. Time perspective was measured using subscales of the Zimbardo Time Perspective Inventory (ZTPI, Zimbardo & Boyd, 1999), Desire for control was measured using a translated version of the Desire for Control Scale (DCS, Burger & Cooper, 1979), and substance use was self-reported. After controlling for age and gender, significant links were found between time perspective and substance use. Desire for control did not appear to be directly related to substance use. The interaction effect between TP and desire for control appeared to be related to substance use. There was evidence that the relation between TP and substance use is buffered by low desire for control. This study converges with previous studies demonstrating the relation between TP and substance use, but provides evidence of the moderating role played by desire for control. Desire for control thus appears as worthy of interest in the analysis of self-regulatory process, and further research on the links between TP and various aspects of control is required. In order to be more effective, the design of future studies and interventions based on time-related issues should consider how desire for control plays a part in establishing vulnerability profiles.

Tsuzuki, Manabu

2015-03-30

This study investigated types of career choice in high school students and examined the effects of career paths on time perspective development. The participants were 4,756 third grade students from nine public high schools in Tokyo. The high school questionnaire survey was conducted throughout autumn of 2008, 2009, and 2010. One year later, 962 graduates participated in the follow-up questionnaire survey by post. Distinguishing gender difference among career paths was found. Girls tend to choose significantly shorter learning careers (p time perspective than other groups (p time perspective between "school to school transition" and "school to work transition". It is suggested that the "school to work transition" tends to be more critical for adolescents and has negative effects on time perspective. These results suggest that the goal content in careers may promote or inhibit the formation of time perspectives during the graduation transition.

A Comparison of the Social-Adaptive Perspective and Functionalist Perspective on Guilt and Shame

Directory of Open Access Journals (Sweden)

Heidi L. Dempsey

2017-12-01

Full Text Available Within the field of guilt and shame two competing perspectives have been advanced. The first, the social-adaptive perspective, proposes that guilt is an inherently adaptive emotion and shame is an inherently maladaptive emotion. Thus, those interested in moral character development and psychopathology should work to increase an individual’s guilt-proneness and decrease an individual’s shame-proneness. The functionalist perspective, in contrast, argues that both guilt and shame can serve a person adaptively or maladaptively—depending on the situational appropriateness, duration, intensity, and so forth. This paper reviews the research conducted supporting both positions; critiques some issues with the most widely used guilt- and shame-proneness measure in the social-adaptive research (the TOSCA and discusses the differences in results found when assessing guilt and shame at the state versus trait level. The conclusion drawn is that although there is broad support for the functionalist perspective across a wide variety of state and trait guilt/shame studies, the functionalist perspective does not yet have the wealth of data supporting it that has been generated by the social-adaptive perspective using the TOSCA. Thus, before a dominant perspective can be identified, researchers need to (1 do more research assessing how the social-adaptive perspective compares to the functionalist perspective at the state level and (2 do more trait research within the functionalist perspective to compare functionalist guilt- and shame-proneness measures with the TOSCA.

In this paper, we use the current and future cosmic microwave background (CMB) experiments to test the Charge-Parity-Time Reversal (CPT) symmetry. We consider a CPT-violating interaction in the photon sector L{sub cs}∼p{sub μ}A{sub ν} F-tilde {sup μν}, which gives rise to a rotation of the polarization vectors of the propagating CMB photons. By combining the 9 yr WMAP, BOOMERanG 2003, and BICEP1 observations, we obtain the current constraint on the isotropic rotation angle α-bar =−2.12±1.14 (1σ), indicating that the significance of the CPT violation is about 2σ. Here, we particularly take the systematic errors of CMB measurements into account. Then, we study the effects of the anisotropies of the rotation angle [Δα( n-hat )] on the CMB polarization power spectra in detail. Due to the small effects, the current CMB polarization data cannot constrain the related parameters very well. We obtain the 95% C.L. upper limit of the variance of the anisotropies of the rotation angle C {sup α}(0) < 0.035 from all of the CMB data sets. More interestingly, including the anisotropies of rotation angle could lower the best-fit value of r and relax the tension on the constraints of r between BICEP2 and Planck. Finally, we investigate the capabilities of future Planck polarization measurements on α-bar and Δα( n-hat ). Benefited from the high precision of Planck data, the constraints of the rotation angle can be significantly improved.

Present and perspective roles of soft X-ray tomography in tokamak plasma position measurements

This paper shows the importance and feasibility of real-time tomography in fusion experiments for the example of soft X-ray (SXR) position measurements. The requirement of non-magnetic real-time diagnostics in low frequencies for ITER is discussed. This is illustrated by recent results of rapid tomographic inversion of SXR measurements on tokamak TCV. Comparison with the magnetic reconstruction data has not only shown the valuable resolution capabilities of both techniques, but also revealed a slight dependence of magnetic measurements on toroidal magnetic field and an unnoticed drift of plasma position observer. A feasibility study using current hardware capacities for programmable real-time tomographic system with plasma position feedback output was carried out. A compact solution is found to be tractable opening wide perspectives for development

Progress on incorporating the patient perspective in outcome assessment in rheumatology and the emergence of life impact measures at OMERACT 9.

LENUS (Irish Health Repository)

Kirwan, John R

2009-09-01

The Patient Perspective Workshop included over 100 researchers and 18 patient participants from 8 countries. Following preconference reading and short plenary presentations, breakout groups considered work undertaken on measurement of sleep, assessing interventions to develop the effective consumer, and assessing psychological and educational interventions. The workshop explored the best way to identify other outcome domains (and instruments) that should be measured in observational or interventional studies with broader intentions than simply altering outcomes captured in the traditional "core set" plus fatigue. Four sleep questionnaires showed promise and will be the subject of further study. The Effective Consumer scale (EC-17) was reviewed and the concept Effective Consumer was well received. Participants thought it worthwhile to measure the skills and attributes of an effective consumer and develop an intervention that would include education in all of the scale\\'s categories. Assessment of educational and psychological interventions requires a wider set of instruments than is currently used; these should relate to the purpose of the intervention. This principle was extended to include wider measures of the impact of disease on life, as indicated in the International Classification of Functioning, Disability and Health. Life impact measure sets covering domains appropriate to different rheumatic conditions and focused on different interventions might be defined by future OMERACT consensus. Measurement instruments within these domains that are valid for use in rheumatic conditions can then be identified and, in the case of psychological and educational interventions, chosen to fit with the purpose of the intervention.

Full Text Available The purpose of this study is to discuss the current state and future of auditing. Expert consensus is used as a basis to examine the current state of auditing and generate modifications both needed and likely to occur in the audit profession. This study contributes to the literature by using the Delphi method to develop predictions as to the direction of the audit industry and discuss the implications associated with these predictions. If auditors can better understand where the profession stands and where it is headed, then they can better prepare for the future. Some predictions emerging from this study relative to future audit practices include increasing automation of audit procedures, more predictive financial statements, continuous auditing of financial statements and transactions, and an increasingly global perspective regarding audit activities.

In the pursuance of equality, behavioural scientists disagree about distinct motivators, that is, consideration of others and prospective calculation for oneself. However, accumulating data suggest that these motivators may share a common process in the brain whereby perspectives and events that did not arise in the immediate environment are conceived. To examine this, we devised a game imitating a real decision-making situation regarding redistribution among income classes in a welfare state. The neural correlates of redistributive decisions were examined under contrasting conditions, with and without uncertainty, which affects support for equality in society. The dorsal anterior cingulate cortex (dACC) and the caudate nucleus were activated by equality decisions with uncertainty but by selfless decisions without uncertainty. Activation was also correlated with subjective values. Activation in both the dACC and the caudate nucleus was associated with the attitude to prefer accordance with others, whereas activation in the caudate nucleus reflected that the expected reward involved the prospective calculation of relative income. The neural correlates suggest that consideration of others and prospective calculation for oneself may underlie the support for equality. Projecting oneself into the perspective of others and into prospective future situations may underpin the pursuance of equality.

Curcumin use in pulmonary diseases: State of the art and future perspectives.

Lelli, Diana; Sahebkar, Amirhossein; Johnston, Thomas P; Pedone, Claudio

2017-01-01

Curcumin (diferuloylmethane) is a yellow pigment present in the spice turmeric (Curcuma longa). It has been used for centuries in Ayurveda (Indian traditional medicine) for the treatment of several diseases. Over the last several decades, the therapeutic properties of curcumin have slowly been elucidated. It has been shown that curcumin has pleiotropic effects, regulating transcription factors (e.g., NF-kB), cytokines (e.g., IL6, TNF-alpha), adhesion molecules (e.g., ICAM-1), and enzymes (e.g., MMPs) that play a major role in inflammation and cancerogenesis. These effects may be relevant for several pulmonary diseases that are characterized by abnormal inflammatory responses, such as asthma or chronic obstructive pulmonary disease, acute respiratory distress syndrome, pulmonary fibrosis, and acute lung injury. Furthermore, some preliminary evidence suggests that curcumin may have a role in the treatment of lung cancer. The evidence for the use of curcumin in pulmonary disease is still sparse and has mostly been obtained using either in vitro or animal models. The most important issue with the use of curcumin in humans is its poor bioavailability, which makes it necessary to use adjuvants or curcumin nanoparticles or liposomes. The aim of this review is to summarize the available evidence on curcumin's effectiveness in pulmonary diseases, including lung cancer, and to provide our perspective on future research with curcumin so as to improve its pharmacological effects, as well as provide additional evidence of curcumin's efficacy in the treatment of pulmonary diseases.

Connections Between Future Time Perspectives and Self-Regulated Learning for Mid-Year Engineering Students: A Multiple Case Study

Science.gov (United States)

Chasmar, Justine

This dissertation presents multiple studies with the purpose of understanding the connections between undergraduate engineering students' motivations, specifically students' Future Time Perspectives (FTPs) and Self-Regulated Learning (SRL). FTP refers to the views students hold about the future and how their perceptions of current tasks are affected by these views. SRL connects the behaviors, metacognition, and motivation of students in their learning. The goals of this research project were to 1) qualitatively describe and document engineering students' SRL strategies, 2) examine interactions between engineering students' FTPs and SRL strategy use, and 3) explore goal-setting as a bridge between FTP and SRL. In an exploratory qualitative study with mid-year industrial engineering students to examine the SRL strategies used before and after an SRL intervention, results showed that students intended to use more SRL strategies than they attempted. However, students self-reported using new SRL strategies from the intervention. Students in this population also completed a survey and a single interview about FTP and SRL. Results showed perceptions of instrumentality of coursework and skills as motivation for using SRL strategies, and a varied use of SRL strategies for students with different FTPs. Overall, three types of student FTP were seen: students with a single realistic view of the future, conflicting ideal and realistic future views, or open views of the future. A sequential explanatory mixed methods study was conducted with mid-year students from multiple engineering majors. First a cluster analysis of survey results of FTP items compared to FTP interview responses was used for participant selection. Then a multiple case study was conducted with data collected through surveys, journal entries, course performance, and two interviews. Results showed that students with a well-defined FTP self-regulated in the present based on their varied perceptions of

Current quests in nucleosynthesis: present and future neutron-induced reaction measurements

2014-03-01

Full Text Available We present some open questions in nucleosynthesis focused on the measurement of relevant neutron capture cross-sections and on new experimental methods. We review the recent 63Ni(n,γ experiment carried out at the n_TOF facility at CERN and its astrophysical implications as well as future experiments and opportunities at n_TOF. We argue some improvements in the measurement of cross-sections by activation arising from a new method for the generation of stellar neutron spectra. We show preliminary results of the experimental validation of the method. We discuss the astrophysical implications of the 181Ta(n,γ stellar cross-section measured with this method. Finally, we describe challenging experiments consisting of in situ radioactive ion beams and stellar neutron beams.

Evolution of Altimetry Calibration and Future Challenges

Science.gov (United States)

Fu, Lee-Lueng; Haines, Bruce J.

2012-01-01

Over the past 20 years, altimetry calibration has evolved from an engineering-oriented exercise to a multidisciplinary endeavor driving the state of the art. This evolution has been spurred by the developing promise of altimetry to capture the large-scale, but small-amplitude, changes of the ocean surface containing the expression of climate change. The scope of altimeter calibration/validation programs has expanded commensurately. Early efforts focused on determining a constant range bias and verifying basic compliance of the data products with mission requirements. Contemporary investigations capture, with increasing accuracies, the spatial and temporal characteristics of errors in all elements of the measurement system. Dedicated calibration sites still provide the fundamental service of estimating absolute bias, but also enable long-term monitoring of the sea-surface height and constituent measurements. The use of a network of island and coastal tide gauges has provided the best perspective on the measurement stability, and revealed temporal variations of altimeter measurement system drift. The cross-calibration between successive missions provided fundamentally new information on the performance of altimetry systems. Spatially and temporally correlated errors pose challenges for future missions, underscoring the importance of cross-calibration of new measurements against the established record.

Drug-eluting stents (DES) have reached a high safety and efficacy profile, becoming the best option for percutaneous coronary interventions (PCI) based revascularization. However, despite their optimal performance, a few concerns remain regarding their use, mainly due to permanent caging of the vessels and its consequences, first of all late stent thrombosis (ST). Bioresorbable scaffolds (BRS) aim to overcome these issues. The results achieved in randomized controlled trials (RCT) by the first generation of poly-L-lactic acid (PLLA) based scaffolds were promising at 1 year, but the first long term reports (albeit flawed by non-optimal implantation technique) have been disappointing, showing, for instance, an increased risk of ST and target vessel myocardial infarction (TV-MI). In such a scenario the advent of a newer generation magnesium (Mg) based BRS is welcome, mainly because of its innovative mechanical and chemical features coupled with well proven biocompatibility. Despite being in its infancy, this technology seems to promise a great potential. In our article, we review the Magmaris (Biotronik AG, Bülach, Switzerland) Mg BRS development from animal models to human use, underscore its best qualities and weaknesses, and provide hints of its possible future perspectives.

2015-05-01

Full Text Available The date palm can adapt to extreme drought, to heat, and to relatively high levels of soil salinity. However, excessive amounts of salt due to irrigation with brackish water lead to a significant reduction in the productivity of the fruits as well as marked decrease in the viable numbers of the date palm trees. It is imperative that the nature of the existing salt adaptation mechanism be understood in order to develop future date palm varieties that can tolerate excessive soil salinity. In this perspective article, several research strategies, obstacles, and precautions are discussed in light of recent advancements accomplished in this field and the properties of this species. In addition to a physiological characterization, we propose the use of a full range of OMICS technologies, coupled with reverse genetics approaches, aimed towards understanding the salt-adaption mechanism in the date palm. Information generated by these analyses should highlight transcriptional and posttranscriptional modifications controlling the salt-adaptation mechanisms. As an extremophile with a natural tolerance for a wide range of abiotic stresses, the date palm may represent a treasure trove of novel genetic resources for salinity tolerance.

Recreational 3,4-methylenedioxymethamphetamine or 'ecstasy': Current perspective and future research prospects.

Science.gov (United States)

Parrott, Andrew C; Downey, Luke A; Roberts, Carl A; Montgomery, Cathy; Bruno, Raimondo; Fox, Helen C

2017-08-01

The purpose of this article is to debate current understandings about the psychobiological effects of recreational 3,4-methylenedioxymethamphetamine (MDMA or 'ecstasy'), and recommend theoretically-driven topics for future research. Recent empirical findings, especially those from novel topic areas were reviewed. Potential causes for the high variance often found in group findings were also examined. The first empirical reports into psychobiological and psychiatric aspects from the early 1990s concluded that regular users demonstrated some selective psychobiological deficits, for instance worse declarative memory, or heightened depression. More recent research has covered a far wider range of psychobiological functions, and deficits have emerged in aspects of vision, higher cognitive skill, neurohormonal functioning, and foetal developmental outcomes. However, variance levels are often high, indicating that while some recreational users develop problems, others are less affected. Potential reasons for this high variance are debated. An explanatory model based on multi-factorial causation is then proposed. A number of theoretically driven research topics are suggested, in order to empirically investigate the potential causes for these diverse psychobiological deficits. Future neuroimaging studies should study the practical implications of any serotonergic and/or neurohormonal changes, using a wide range of functional measures.

Current perspectives of 14C-isotope measurement in biomedical accelerator mass spectrometry

International Nuclear Information System (INIS)

Lappin, Graham; Garner, R.Colin

2004-01-01

Accelerator mass spectrometry (AMS) is an extremely sensitive nuclear physics technique developed in the mid-70's for radiocarbon dating of historical artefacts. The technique centres round the use of a tandem Van de Graaff accelerator to generate the potential energy to permit separation of elemental isotopes at the single atom level. AMS was first used in the early 90's for the analysis of biological samples containing enriched 14 C for toxicology and cancer research. Since that time biomedical AMS has been used in the study of (1) metabolism of xenobiotics in animals and humans (2) pathways of drug metabolism (3) biomarkers (4) metabolism of endogenous molecules including vitamins (5) DNA and protein binding studies and (6) clinical diagnosis. A new drug development concept which relies on the ultrasensitivity of AMS known as human microdosing (Phase 0) is being used to obtain early human metabolism information of candidate drugs arising out of discovery. These various aspects of AMS are reviewed in this article and a perspective on future applications of AMS provided. (orig.)

Hirsch, Jameson K; Molnar, Danielle; Chang, Edward C; Sirois, Fuschia M

Temporal perspective, including views about future goals, may influence motivational processes related to health. An adaptive sense of future orientation is linked to better health, but little research has examined potential underlying factors, such as vitality. In a sample of 101 primary care patients, we examined whether belief in the changeability of the future was related to mental and physical energization and, in turn, to health-related quality of life. Participants were working, uninsured primary care patients, who completed self-report measures of future orientation, vitality, and health-related quality of life. Mediation models, covarying age, sex, and race/ethnicity indicated that vitality significantly mediated the association between future orientation and the outcomes of general health, mental health, social functioning, bodily pain, and role limitations due to emotional and physical reasons. Vitality exerted an indirect-only effect on the relation between future orientation and physical functioning. Our findings suggest that adaptive beliefs about the future may promote, or allow access to, physical and mental energy and, in turn, may result in better mental and physical health functioning. Individual-level and public health interventions designed to promote future orientation and vitality may beneficially influence quality of life and well-being.

In vivo microrobots for natural orifice transluminal surgery. Current status and future perspectives.

Science.gov (United States)

Forgione, A

2009-06-01

The possibility to operate inside the peritoneal cavity through small holes performed in hollow organs that is presented by Natural Orifice Transluminal Endoscopic Surgery (NOTES) represents a major paradigm shift in general surgery. While this new approach seems very appealing from patients' perspectives because it eliminates completely abdominal wall aggression and promises to reduce postoperative pain, it is very challenging for surgeons because of the major constraints imposed by both the mode of access and the limited technology currently available. For this reason NOTES applications at the present time are performed by only a few surgeons and mainly to perform non-complex procedures. While new devices are under development, many of them are trying mainly to simply improve current endoscopic platforms and seem not to offer breakthrough solutions. The numerous challenges introduced by natural orifice approaches require a radical shift in the conception of new technologies in order to make this emerging operative access safe and reproducible. The convergence of several enabling technologies in the field of miniaturization, communication and micro-mechatronics brings the possibility to realize on a large scale the revolutionary concept of miniature in vivo co-operative robots. These robots provide vision and task assistance without the constraints of the entry incision and have been shown in experimental settings to possess many qualities that could be ideal to partner with Natural Orifice Surgery. This article explores the current status of microrobotics as well as presents potential future scenarios of their applications in NOTES.

Informatics in clinical research in oncology: current state, challenges, and a future perspective.

Chahal, Amar P S

2011-01-01

The informatics landscape of clinical trials in oncology has changed significantly in the last 10 years. The current state of the infrastructure for clinical trial management, execution, and data management is reviewed. The systems, their functionality, the users, and the standards available to researchers are discussed from the perspective of the oncologist-researcher. Challenges in complexity and in the processing of information are outlined. These challenges include the lack of communication and information-interchange between systems, the lack of simplified standards, and the lack of implementation and adherence to the standards that are available. The clinical toxicology criteria from the National Cancer Institute (CTCAE) are cited as a successful standard in oncology, and HTTP on the Internet is referenced for its simplicity. Differences in the management of information standards between industries are discussed. Possible future advances in oncology clinical research informatics are addressed. These advances include strategic policy review of standards and the implementation of actions to make standards free, ubiquitous, simple, and easily interpretable; the need to change from a local data-capture- or transaction-driven model to a large-scale data-interpretation model that provides higher value to the oncologist and the patient; and the need for information technology investment in a readily available digital educational model for clinical research in oncology that is customizable for individual studies. These new approaches, with changes in information delivery to mobile platforms, will set the stage for the next decade in clinical research informatics.

Development of quantum perspectives in modern physics

Directory of Open Access Journals (Sweden)

Charles Baily

2009-03-01

Full Text Available Introductory undergraduate courses in classical physics stress a perspective that can be characterized as realist; from this perspective, all physical properties of a classical system can be simultaneously specified and thus determined at all future times. Such a perspective can be problematic for introductory quantum physics students, who must develop new perspectives in order to properly interpret what it means to have knowledge of quantum systems. We document this evolution in student thinking in part through pre- and post-instruction evaluations using the Colorado Learning Attitudes about Science Survey. We further characterize variations in student epistemic and ontological commitments by examining responses to two essay questions, coupled with responses to supplemental quantum attitude statements. We find that, after instruction in modern physics, many students are still exhibiting a realist perspective in contexts where a quantum-mechanical perspective is needed. We further find that this effect can be significantly influenced by instruction, where we observe variations for courses with differing learning goals. We also note that students generally do not employ either a realist or a quantum perspective in a consistent manner.

Even though the definition of the Joint Director of Laboratories (JDL) "fusion levels" were established in 1987, published 1991, revised in 1999 and 2004, the meaning, effects, control and optimization of interactions among the fusion levels have not as yet been fully explored and understood. Specifically, this is apparent from the abstract JDL definitions of "Levels 2/3 Fusion" - situation and threat assessment (SA/TA), which involve deriving relations among entities, e.g., the aggregation of object states (i.e., classification and location) in SA, while TA uses SA products to estimate/predict the impact of actions/interactions effects on situations taken by the participant entities involved. Given all the existing knowledge in the information fusion and human factors literature, (both prior to and after the introduction of "fusion levels" in 1987) there are still open questions remaining in regard to implementation of knowledge representation and reasoning methods under uncertainty to afford SA/TA. Therefore, to promote exchange of ideas and to illuminate the historical, current and future issues associated with Levels 2/3 implementations, leading experts were invited to present their respective views on various facets of this complex problem. This paper is a retrospective annotated view of the invited panel discussion organized by Ivan Kadar (first author), supported by John Salerno, in order to provide both a historical perspective of the evolution of the state-of-the-art (SOA) in higher-level "Levels 2/3" information fusion implementations by looking back over the past ten or more years (before JDL), and based upon the lessons learned to forecast where focus should be placed to further enhance and advance the SOA by addressing key issues and challenges. In order to convey the panel discussion to audiences not present at the panel, annotated position papers summarizing the panel presentation are included.

Measuring the perceived quality of ophthalmology services in private organizations. A marketing perspective

2018-01-01

Nowadays, the competition registered on the Romanian markets regarding the activity of private ophthalmology organizations has raised their interest in developing consumer-oriented strategies. The key factor that assures a differentiation as well as a competitive advantage is the service quality from a marketing perspective. Objectives: From a marketing perspective, service quality is measured as a perceived discrepancy between the consumers’ expectations and was actually performed in health care services. The most widely and validated measurement is the SERVQUAL scale. However, a variety of SERVQUAL scales have been applied in different health care environments without taking into consideration the specialty of the health care service. Thus, the objective of this paper was to measure the service quality in the Romanian ophthalmology private organizations using the SERVQUAL measurement, by identifying the SERVQUAL dimensions, which register the highest and the lowest gap scores. Materials and methods: The instrument for data collection was the SERVQUAL self-administered questionnaire that consisted of 22 items measured on a 5-point Likert scale. The sample size encompassed 100 participants and the sampling technique was the snowball. The internal consistency, validity and the reliability of the SERVQUAL scale was determined by the Cronbach’s alpha coefficients and factor analysis. The SERVQUAL questionnaire focused on 5 dimensions (tangibles, reliability, assurance, empathy and responsiveness) and each dimension, in its turn, was characterized by different items. Results: The mean age of the participants was 49.52 years, with a mean income of 3031 Romanian Currency and the mean period of wearing eyeglasses was 5 years (±2). Further, there were 47% females and 53% males. The overall internal consistency of the SERVQUAL scale, as well as the dimensions’ internal consistency were all above 0.7 and the factor analysis revealed that the items loaded properly on
