    Full Text Available There has been some acknowledgement in the published literature that reflection is a crucial element of the evidence based library and information practice (EBLIP model we have adopted (Booth 2004, 2006; Grant 2007; Helliwell 2007. As we work through a problem and try to incorporate the best available evidence into our decision making, reflection is required at several stages, including the very identification of the problem through to our assessment of the process itself and what we have learned in order to inform future practice. However, reflection and reflective writing have not fully been integrated into the process we espouse, and very little has been done to look more closely at this element of the model and how it can be integrated into professional learning.In a recently published research article, Sen (2010 confirms the relationship between reflection and several aspects of professional practice. These include critical review and decision making, two aspects that are tied closely to the evidence based process. Sen notes: Students were more likely to show evidence of learning, self‐development, the ability to review issues crucially, awareness of their own mental functions, ability to make decision [sic] and being empowered when they had mastered the art of reflective practice and the more deeply analytical reflective writing. (p.84 EBLIP (the journal tries to incorporate elements of reflection within the articles we publish. While we clearly believe in the need for our profession to do quality research and publish that research so that it can be accessible to practitioners, we also know that research cannot be looked at in isolation. Our evidence summaries are one way of reflecting critically on previously published research, and in the same vein, our classics bring older research studies back to the foreground. This work needs to continue to be discussed and looked at for its impact on our profession.More directly, the Using

    A preliminary attempt is made to understand the thought process and the evolution of the nervous system on the same footing as regeneration processes obeying certain recursive algebraic rules which possibly economize the information content of the increasingly complex structural-functional correlate of the evolving and thinking nervous system.

  6. 'It's everywhere!' young Swedish people's thoughts and reflections about pornography.

    2006-12-01

    Pornography is one of the most sought-after topics on the Internet, and is easily available for anyone, including children and adolescents. At youth centres, nurse-midwives have noticed that young people have different kinds of questions about sexual practices compared with a few years ago. The aim of this study was to gain an understanding of thoughts and reflections about pornography consumption, and its possible influence on sexual practices, among young women and men. The staff at a youth centre in a city in central Sweden asked the visitors if they had seen pornography and if they wanted to be interviewed about their experiences. Ten young women and eight men, aged 16-23 years, participated. In-depth interviews were performed and open-ended questions about pornography and sexuality were posed. The interviews were tape-recorded and transcribed verbatim. Data were analysed according to grounded theory. The core category 'Living with the current sexual norm' depicted how pornography created sexual expectations and demands, for instance, to perform certain sexual acts. The informants expressed contradictory feelings towards pornography and felt that sexuality was separated from intimacy. A moral attitude was described and examples of stereotypic gender roles were given. To deal with the current sexual norm, informants had different individual handling strategies and attitudes to pornography, namely liberal, normalization, distance, feminist or conservative. Limitations of this study were the small sample size and that results from a qualitative research study cannot be generalized. The results contribute to an understanding of how pornographic material can influence young peoples' thoughts, reflections and sexual behaviour. This indicates the importance, for personnel at youth centres and schools, to discuss sexual behaviour and how sexuality is portrayed in pornographic material with young people.

    2009-04-16

    Reflective thought (critical thinking) is essential to the medical student who hopes to become an effective physician. John Dewey, one of America's foremost educators in the early twentieth century, revolutionized critical thinking and its role in education. In the mid twentieth century Hannah Arendt provided profound insights into the problem of diminishing human agency and political freedom. Taken together, Dewey's insight regarding reflective thought, and Arendt's view of action, speech, and power in the public realm, provide mentors and teachers of medical students guidance in the training of thought and the need for its effective projection at the patient's bedside and in the community.

    Work in hospice and palliative medicine can be stressful. A variety of methods have been used to mitigate workplace stress including mindfulness mediation, reflective writing, and physical activity. An intervention implemented at our institution is a "Thought for the Day," a short reflection on a piece of poetry, music, or religious writing. Although this practice may be commonplace in the field of hospice and palliative medicine, no literature has been published about its perceived utility by team members with various competing demands on their time. This study's objective was to obtain a better understanding about the perception and utility of a Thought for the Day held by clinicians rounding on an academic palliative medicine consult service. A survey, containing qualitative and quantitative elements was sent to faculty, staff, and learners who participated in a Thought for the Day over the 18 months between March 2013 and October 2014. Twenty-eight responses were returned and analyzed. Most participants (23 of the 28) felt that the Thought for the Day was an important use of their time on the academic consult service. Differences were seen by gender and team role. Additionally, it was reported that the Thought for the Day improved the participants' perception of teamwork. The use of a Thought for the Day reflection may be beneficial and constructive even for a busy academic consult service.

  10. Formulation of the verbal thought process based on generative rules

    Energy Technology Data Exchange (ETDEWEB)

    Suehiro, N; Fujisaki, H

    1984-01-01

    As assumption is made on the generative nature of the verbal thought process, based on an analogy between language use and verbal thought. A procedure is then presented for acquiring the set of generative rules from a given set of concept strings, leading to an efficient representation of verbal knowledge. The non-terminal symbols derived in the acquisition process are found to correspond to concepts and superordinate concepts in the human process of verbal thought. The validity of the formulation and the efficiency of knowledge representation is demonstrated by an example in which knowledge of biological properties of animals is reorganized into a set of generative rules. The process of inductive inference is then defined as a generalization of the acquired knowledge, and the principle of maximum simplicity of rules is proposed as a possible criterion for such generalization. The proposal is also tested by an example in which only a small part of a systematic body of knowledge is utilized to make interferences on the unknown parts of the system. 6 references.

  11. Art and Liturgy Thoughts and Reflections on Beuronense Art in São Paulo

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available We will present some thoughts and reflections on art and liturgy that will help us in understanding the new sacred artistic trends that emerged in the mid-19th century in Europe. The writings of Luigi Pareyson, Etienne Gilson and Albert Rouet were chosen for this exercise because their works contain questions about the relationship between art and aesthetics, sacred art and liturgy. We will continue with a brief study of the postulates of Peter Lenz about the Beuron aesthetics and their assimilation by other monasteries, as well as religious brotherhoods in São Paulo in the early 20th century.

  12. The neural basis of temporal order processing in past and future thought.

    Although growing evidence has shown that remembering the past and imagining the future recruit a common core network of frontal-parietal-temporal regions, the extent to which these regions contribute to the temporal dimension of autobiographical thought remains unclear. In this fMRI study, we focused on the event-sequencing aspect of time and examined whether ordering past and future events involve common neural substrates. Participants had to determine which of two past (or future) events occurred (or would occur) before the other, and these order judgments were compared with a task requiring to think about the content of the same past or future events. For both past and future events, we found that the left posterior hippocampus was more activated when establishing the order of events, whereas the anterior hippocampus was more activated when representing their content. Aside from the hippocampus, most of the brain regions that were activated when thinking about temporal order (notably the intraparietal sulcus, dorsolateral pFC, dorsal anterior cingulate, and visual cortex) lied outside the core network and may reflect the involvement of controlled processes and visuospatial imagery to locate events in time. Collectively, these findings suggest (a) that the same processing operations are engaged for ordering past events and planned future events in time, (b) that anterior and posterior portions of the hippocampus are involved in processing different aspects of autobiographical thought, and (c) that temporal order is not necessarily an intrinsic property of memory or future thought but instead requires additional, controlled processes.

    Critical thinking skills are essential for the successful dentist, yet few explicit skillsets in critical thinking have been developed and published in peer-reviewed literature. The aims of this article are to 1) offer an assessable critical thinking teaching model with the expert's thought process as the outcome, learning guide, and assessment instrument and 2) offer three critical thinking skillsets following this model: for geriatric risk assessment, technology decision making, and situation analysis/reflections. For the objective component, the student demonstrates delivery of each step in the thought process. For the subjective component, the student is judged to have grasped the principles as applied to the patient or case. This article describes the framework and the results of pilot tests in which students in one year at this school used the model in the three areas, earning scores of 90% or above on the assessments. The model was thus judged to be successful for students to demonstrate critical thinking skillsets in the course settings. Students consistently delivered each step of the thought process and were nearly as consistent in grasping the principles behind each step. As more critical thinking skillsets are implemented, a reinforcing network develops.

  15. Thought probes during prospective memory encoding: Evidence for perfunctory processes

    For nearly 50 years, psychologists have studied prospective memory, or the ability to execute delayed intentions. Yet, there remains a gap in understanding as to whether initial encoding of the intention must be elaborative and strategic, or whether some components of successful encoding can occur in a perfunctory, transient manner. In eight studies (N = 680), we instructed participants to remember to press the Q key if they saw words representing fruits (cue) during an ongoing lexical decision task. They then typed what they were thinking and responded whether they encoded fruits as a general category, as specific exemplars, or hardly thought about it at all. Consistent with the perfunctory view, participants often reported mind wandering (42.9%) and hardly thinking about the prospective memory task (22.5%). Even though participants were given a general category cue, many participants generated specific category exemplars (34.5%). Bayesian analyses of encoding durations indicated that specific exemplars came to mind in a perfunctory manner rather than via strategic, elaborative mechanisms. Few participants correctly guessed the research hypotheses and changing from fruit category cues to initial-letter cues eliminated reports of specific exemplar generation, thereby arguing against demand characteristics in the thought probe procedure. In a final experiment, encoding duration was unrelated to prospective memory performance; however, specific-exemplar encoders outperformed general-category encoders with no ongoing task monitoring costs. Our findings reveal substantial variability in intention encoding, and demonstrate that some components of prospective memory encoding can be done “in passing.” PMID:29874277

First, we explain how the dominating role of the human body in nursing textbooks disappears in the mid-20th century. This transformation can of course be attributed......In this article, we address how the professionalization process is reflected in the way Danish nursing textbooks present 'nursing' to new members of the profession during the 20th century. The discussion is based on a discourse analysis of seven Danish textbooks on basic nursing published between...... and not causes. The second part of the analysis shows that along with 'the disappearance of the body', a second discursive change appears: the role of doctors and medicine changes fundamentally from about mid-20th century. Finally, we argue that this discursive reorganization enabling new patterns of thought...

    Weighting patterns for loudness obtained using the reverse correlation method are thought to reveal the relative contributions of different frequency regions to total loudness, the equivalent of specific loudness. Current models of loudness assume that specific loudness is determined by peripheral...... processes such as compression and masking. Here we test this hypothesis using 20-tone harmonic complexes (200Hz f0, 200 to 4000Hz, 250 ms, 65 dB/Component) added in opposite phase relationships (Schroeder positive and negative). Due to the varying degree of envelope modulations, these time-reversed harmonic...... processes and reflect a central frequency weighting template....

  19. THOUGHTS ON THE REGIONALIZATION PROCESS IN COMPARATIVE LAW

    2013-05-01

    Full Text Available Regionalization is a complex and smooth process in terms of territorial organization of the states which chose this form of organization, but also from the perspective of how the regional systems understood to exercise their competences. The regionalization process did not only yield profit for the inhabitants of those administrative entities, but it also caused problems to national governors (e.g. demands for the federalization of the state in question, proposals to gain independence from the state they are part of, issues related to state security – terrorists attacks etc.. Our paper shall conduct an assessment over two states which chose this form of regionalization: The United Kingdom of Great Britain and North Ireland and Spain. Given the context of the upcoming constitutional and legislative changes envisaged by the Romanian government, we consider that our research can be regarded as a useful tool, designed to develop certain constitutional directives, which are intended to acquire the best solutions from European experiences.

  20. Food for thought: Conditions for discourse reflection in the light of environmental assessment

    2010-01-01

    People tend to take notice of what is happening around them selectively. Discourses-frames through which actors give meaning to aspects of the world-act as built-in filters that distinguish relevant from irrelevant data. Use of knowledge generated by environmental assessments (EAs) in decision-making may be understood from this perspective. Environmental knowledge that is inconsistent with dominant discourses runs the risk of being ignored. Discourses on the value of EA as a tool for decision-making may have a similar effect. Stimulating decision-makers and stakeholders to critically reflect on and reconsider their discourses in the light of EAs-also known as frame reflection or policy learning-may enhance the probability that these assessments and the knowledge that they generate impact upon decision-making. Up to now little has been written about how discourse reflection in the context of EA can be promoted. Valuable inputs are fragmented over different bodies of literature. In this paper we draw from these bodies to identify favourable conditions for discourse reflection.

    2005-08-01

    This document is to report the results of existing seismic data re-processing around Horonobe town, Hokkaido, Japan, which is a part of the Horonobe Underground Research Project. The main purpose of this re-processing is to recognize the subsurface structure of Omagari Fault and fold system around Omagari Fault. The seismic lines for re-processing are TYHR-A3 line and SHRB-2 line, which JAPEX surveyed in 1975. Applying weathering static correction using refraction analysis and noise suppression procedure, we have much enhanced seismic profile. Following information was obtained from seismic re-processing results. TYHR-A3 line: There are strong reflections, dipping to the west. These reflections are corresponding western limb of anticline to the west side of Omagari Fault. SHRB-2 line: There are strong reflections, dipping to the west, at CDP 60-140, while there are reflections, dipping to the east, to the east side of CDP 140. These reflections correspond to the western limb and the eastern limb of the anticline, which is parallel to Omagari FAULT. This seismic re-processing provides some useful information to know the geological structure around Omagari Fault. (author)

  2. Mental Representation in The Thought of Sidney Blatt: Developmental Processes.

    Science.gov (United States)

    Auerbach, John S; Diamond, Diana

    2017-06-01

    Mental representation was a central construct in Sidney Blatt's contributions to psychology and psychoanalysis. This brief review demonstrates that Blatt's understanding of representation was always informed by basic psychoanalytic concepts like the centrality of early caregiver-infant relationships and of unconscious mental processes. Although Blatt's earlier writings were informed by psychoanalytic ego psychology and Piagetian cognitive developmental psychology, they focused nonetheless on how an individual uses bodily and relational experiences to construct an object world; they also consistently presented object representations as having significant unconscious dimensions. From the mid-1980s onward, Blatt's contributions, in dialogue with his many students, moved in an even more experiential/relational direction and manifested the influence of attachment theory, parent-infant interaction research, and intersubjectivity theory. They also incorporated contemporary cognitive psychology, with its emphasis on implicit or procedural, rather than explicit, dimensions as a means of accounting for aspects of object representations that are not in conscious awareness. Throughout his career, however, Blatt regarded mental representation as the construct that mediates between the child's earliest bodily and relational experiences and the mature adult's symbolic, most emotionally profound capacities.

  3. The borderlands of waking: Quantifying the transition from reflective thought to hallucination in sleep onset.

    Speth, Clemens; Speth, Jana

    2016-04-01

    We lose waking consciousness spontaneously and regularly over the circadian cycle. It seems that every time we fall asleep, reflective thinking gradually gives way to our interactions with an imaginary, hallucinatory world that brings multimodal experiences in the absence of adequate external stimuli. The present study investigates this transition, proposing a new measure of hallucinatory states. Reflective thinking and motor imagery were quantified in 150 mentation reports provided by 16 participants after forced awakenings from different physiology-monitored time intervals after sleep onset. Cognitive agency analysis and motor agency analysis--which are objective (grammatical-semantic) tools derived from linguistic theories--show (i) a decrease in reflective thinking which sleepers would need to acknowledge the hallucinatory quality of their state, and (ii) an increase in motor imagery, indicating interactions with a hallucinatory world. By mapping these spontaneous changes in human consciousness onto physiology, we can in the long run explore the conditions of its decline, and possibilities for treatment.

    Science.gov (United States)

    Blanco Men ndez, R; Aguado Balsas, A M

    Reasoning and logical thought processes have traditionally been attributed to frontal lobe function or,on the other hand, have been considered as diffuse functions of the brain. However, there is today evidence enough about the possibility to find dissociations in thought processes, depending on logical structure of the experimental tasks and referring to different areas of the brain, frontal and post rolandic ones. To study possible dissociations between thought structures corresponding to categorical and relational logic, on one hand, and propositional logic on the other hand. The case of a brain injured patient with vascular etiology, localized in left frontal parietal cortex, is presented. A specific battery of reasoning tests has been administered. . A differential performance at some reasoning experimental tasks has been found depending on such logical conceptual structures. The possibility of establishing dissociations among certain logical thought and intelectual functions depending on localization of possible brain lesion (frontal versus temporal) is discussed.

  6. The default network and self-generated thought: component processes, dynamic control, and clinical relevance

    2014-01-01

    Though only a decade has elapsed since the default network was first emphasized as being a large-scale brain system, recent years have brought great insight into the network’s adaptive functions. A growing theme highlights the default network as playing a key role in internally-directed—or self-generated—thought. Here, we synthesize recent findings from cognitive science, neuroscience, and clinical psychology to focus attention on two emerging topics as current and future directions surrounding the default network. First, we present evidence that self-generated thought is a multi-faceted construct whose component processes are supported by different subsystems within the network. Second, we highlight the dynamic nature of the default network, emphasizing its interaction with executive control systems when regulating aspects of internal thought. We conclude by discussing clinical implications of disruptions to the integrity of the network, and consider disorders when thought content becomes polarized or network interactions become disrupted or imbalanced.

    Lucena, Marcela Adriana da Silva; Bezerra, Adriana Falangola Benjamin

    2012-09-01

    This study addresses mental health and, based on a conceptual review, offers considerations on the management of deinstitutionalization processes regarding individuals interned in long-stay psychiatric institutions. Elements concerning asylum formation and logic are discussed, along with the mechanisms necessary for the effective change in paradigm and practices, with deinstitutionalization and psychosocial rehabilitation as the core issues. Reflections are offered regarding management actions committed to the psychosocial model, linking such actions to the application of the components of care and going beyond the articulation of the tools of mental health policy. Theoretical reflection offers suggestions referring to the qualification processes of mental health professionals, deinstitutionalization in the management of the Unified Health System and tripartite action with co-accountability in actions and financing. The final considerations recognize the bureaucratic obstacles in the public realm and propose facing these challenges as a management challenge, along with processes of change that can radically commit to the lives of people, thereby broadening the discussion to the ethical realm.

  11. Autonomous dynamics in neural networks: the dHAN concept and associative thought processes

    Science.gov (United States)

    Gros, Claudius

    2007-02-01

    The neural activity of the human brain is dominated by self-sustained activities. External sensory stimuli influence this autonomous activity but they do not drive the brain directly. Most standard artificial neural network models are however input driven and do not show spontaneous activities. It constitutes a challenge to develop organizational principles for controlled, self-sustained activity in artificial neural networks. Here we propose and examine the dHAN concept for autonomous associative thought processes in dense and homogeneous associative networks. An associative thought-process is characterized, within this approach, by a time-series of transient attractors. Each transient state corresponds to a stored information, a memory. The subsequent transient states are characterized by large associative overlaps, which are identical to acquired patterns. Memory states, the acquired patterns, have such a dual functionality. In this approach the self-sustained neural activity has a central functional role. The network acquires a discrimination capability, as external stimuli need to compete with the autonomous activity. Noise in the input is readily filtered-out. Hebbian learning of external patterns occurs coinstantaneous with the ongoing associative thought process. The autonomous dynamics needs a long-term working-point optimization which acquires within the dHAN concept a dual functionality: It stabilizes the time development of the associative thought process and limits runaway synaptic growth, which generically occurs otherwise in neural networks with self-induced activities and Hebbian-type learning rules.

  13. Thought disorder in schizophrenia: impairment in contextual processing via integrative failures in cognition.

    Science.gov (United States)

    Patniyot, Nicholas S

    2011-10-01

    Formal thought disorder is a critical dysfunction in schizophrenia whose cause remains uncertain, but whose explanation may greatly further our understanding of the disease. Thought disorder in patients with schizophrenia has been hypothesized to involve a disturbance in the internal representation of context. Positive symptoms of schizophrenia attributable to thought disorder display a lack of organization that may be accounted for by an absence of normal contextual processing occurring within the operations of the executive system. But the precise nature and pervasiveness of the deficient cognitive operation remain undistinguished. It is proposed here that the assimilatory functions of the brain appear to lack the ability to perform a particular type of integrative operation when presented with heterogeneous information. This deficit involves committing cognitive misattributions through a confusion of mental terms via a process in thought analogous to a linguistic failure to correctly interpret deictic referents. Both proposed deficits in mental deixis and analogous "metarepresentational" deficits in schizophrenia potentially involve a failure to draw information for a conclusion from a separate framework of relations in integrative fashion. These deficits appear to involve a failure to take an interpreted piece of information as an output from a particular mental task and incorporate it into a new operational scheme, and a central attribute to the deficit is that there is a loss of an effective or adequate integration of separate strata of information. Potential neurobiological correlates to such a system based on current knowledge about schizophrenia neurocircuitry, as well as implications for testing, are also discussed.

  14. Signal processing issues in reflection tomography

    2001-12-01

    This dissertation focuses on signal modeling and processing issues of the following problems in reflection tomography: synthetic aperture radar (SAR) imaging of a runway and surroundings from an aircraft approaching for landing, acoustic imaging of objects buried in soil, and lidar imaging of underwater objects. The highly squinted geometry of runway imaging necessitates the incorporation of wavefront curvature into the signal model. We investigate the feasibility of using the wavenumber-domain (ω - k) SAR inversion algorithm, which models the actual curvature of the wavefront, for runway imaging. We demonstrate the aberrations that the algorithm can produce when the squint angle is close to 90° and show that high-quality reconstruction is still possible provided that the interpolation is performed accurately enough, which can be achieved by increasing the temporal sampling rate. We compare the performance with that of a more general inversion method (GIM) that solves the measurement equation directly. The performances of both methods are comparable in the noise- free case. Being inherently robust to noise, GIM produces superior results in the noisy case. We also present a solution to the left-right ambiguity of runway imaging using interferometric processing. In imaging of objects buried in soil, we pursue an acoustic approach primarily for detection and imaging of cultural artifacts. We have developed a mathematical model and associated computer software in order to simulate the signals acquired by the actual experimental system, and a bistatic SAR-type algorithm for reconstruction. In the reconstructions from simulated data, objects were detectable, but near-field objects suffered from shifts and smears. To account for wavefront curvature, we formulated processing of the simulated data using the 3-D version of the monostatic ω - k algorithm. In lidar imaging of underwater objects, we formulate the problem as a 3-D tomographic reconstruction problem. We have

Employing a 200-ms-long broadband noise burst as input signal, the critical delay separating these two binaural phenomena was found to be 7–10 ms. It was suggested that the critical delay refers to a temporal window that is employed......, resulting in a critical delay of about 2–3 ms for 20-ms-long stimuli. Hence, for very short stimuli the temporal window or critical delay exhibits values similar to the auditory temporal resolution as, for instance, observed in gap-detection tasks. It is suggested that the larger critical delay observed...

    The catechol-O-methyltransferase (COMT) enzyme is a major determinant of prefrontal dopamine levels. The Val(158)Met polymorphism affects COMT enzymatic activity and has been associated with variation in executive function and affective processing. This study investigated the effect of COMT genotype on the flexible modulation of the balance between processing self-generated and processing stimulus-oriented information, in the presence or absence of affective distractors. Analyses included 124 healthy adult participants, who were also assessed on standard working memory (WM) tasks. Relative to Val carriers, Met homozygotes made fewer errors when selecting and manipulating self-generated thoughts. This effect was partly accounted for by an association between COMT genotype and visuospatial WM performance. We also observed a complex interaction between the influence of affective distractors, COMT genotype and sex on task accuracy: male, but not female, participants showed a sensitivity to the affective distractors that was dependent on COMT genotype. This was not accounted for by WM performance. This study provides novel evidence of the role of dopaminergic genetic variation on the ability to select and manipulate self-generated thoughts. The results also suggest sexually dimorphic effects of COMT genotype on the influence of affective distractors on executive function. © The Author (2014). Published by Oxford University Press.

  1. Desirable and undesirable future thoughts call for different scene construction processes.

    2015-01-01

    Despite the growing interest in the ability of foreseeing (episodic future thinking), it is still unclear how healthy people construct possible future scenarios. We suggest that different future thoughts require different processes of scene construction. Thirty-five participants were asked to imagine desirable and less desirable future events. Imagining desirable events increased the ease of scene construction, the frequency of life scripts, the number of internal details, and the clarity of sensorial and spatial temporal information. The initial description of general personal knowledge lasted longer in undesirable than in desirable anticipations. Finally, participants were more prone to explicitly indicate autobiographical memory as the main source of their simulations of undesirable episodes, whereas they equally related the simulations of desirable events to autobiographical events or semantic knowledge. These findings show that desirable and undesirable scenarios call for different mechanisms of scene construction. The present study emphasizes that future thinking cannot be considered as a monolithic entity.

    2017-01-01

    This study explores thought patterns of Jewish Ashkenazi Ultra-Orthodox pedophiles in Israel and how they resolve the contradiction between their commitment to Jewish Law and having committed sexual offenses against minors. Ten adult men participated in this study. Using open semistructured interviews, their cognitive distortions before, during, and after the abuse were examined. Content analysis revealed that participants used cognitive distortions based on their own world of Jewish Law and social-cultural values. The insular nature of Ultra-Orthodox society and its many prohibitions, especially regarding sexuality, tempted offenders to test boundaries. When sexual drive was high, internal control mechanisms were ineffective even in presence of external control mechanisms. Some participants recognized the contradiction between their behaviors and being Ultra-Orthodox Jews, and others did not. Based on the findings, a flow chart was devised describing the cognitive processes of Jewish Ultra-Orthodox pedophiles. Theoretical and practical implications of the results were examined.

    2011-12-01

    The objective of this qualitative, exploratory-descriptive study was to analyze the group process of a nursing team at Hospital de Clínicas de Porto Alegre (HCPA), under the light of Pichon-Rivière's Operative Group Theory. Data collection took place in 2008, using a semi-structured questionnaire and focal group. The group work concept is one of the four categories that resulted from the study, and is the object of approach in the present article. It was found that the knowledge about the group process must be shared, disseminated and discussed since the undergraduate studies and developed across the professional career. As the team learns and is able to identify the main indicators of the group process, it becomes possible to improve operatively, considering not only the outcomes but mainly the course covered until achieving the goal, aiming at group learning.

    2016-06-01

    This paper examines the name as an issue of interest in the psychology field. In thinking about the role played by names for some of the most important approaches on the psychology panorama, it has been found that the analysis of names can be used as an instrument for the investigation of thought formation processes, or as an element in the process of constructing personal identity. In the first case, the focus is on the so-called "common" names, which designate objects; in the second case, instead, it is on people's given names and on the way they are perceived by their bearers and those who surround them. We have examined both domains, since it is essential to understand how the psychological concepts related to names develop in children's minds, if we aim to grasp their importance as designators of people's internal and external realities. Lastly, we have proposed our own view of the person's name, linked to the relational systems perspective which essentially sees the name as a signifier or "representative" of the child-parent relationship, while the "relationship" is the signified.

    A study was conducted to examine the role of concrete and formal operations in a young and old population. In addition, the present study explored the relation between operational thought and Cattell's concept of fluid and crystallized intelligence, as well as the role of differential living arrangements in maintaining operational thought. Eighty females from three age groups (18-20 years, 60-70 years and 70-80 years of age) were tested on a series of Piagetian tasks and indices of fluid and crystallized intelligence. The findings supported the notion that age-related performance differences occur in the area of formal operational thought prior to the time they occur in concrete operational thought. Except for the young sample, the operational tasks were found to be unrelated to fluid intelligence at the age levels represented in this study. Living independently as opposed to living in an old age home did not appear to be a significant factor in maintaining operational thought. Discussion focused on the necessity of identifying those factors which influence the developmental course of formal operational thought across the life span.

  12. Evidence for skill level differences in the thought processes of golfers during high and low pressure situations.

    Directory of Open Access Journals (Sweden)

    Amy Elizabeth Whitehead

    2016-01-01

    Full Text Available Two studies examined differences in the cognition of golfers with differing levels of expertise in high and low pressure situations. In study 1, six high skill and six low skill golfers performed six holes of golf, while verbalizing their thoughts using Think Aloud (TA protocol. Higher skilled golfers’ cognitive processes centered more on planning in comparison to lower skilled golfers. Study 2 investigated whether thought processes of golfers changed in response to competitive pressure. Eight high skill and eight moderate skilled golfers, completed a practice round and a competition round whilst verbalizing thoughts using TA. To create pressure in the competition condition, participants were instructed that monetary prizes would be awarded to the top three performers and scores of all golfers would be published in a league table in the club house. When performing under competitive pressure, it was found that higher skilled golfers were more likely to verbalize technical rules compared to practice conditions, especially during putting performance. This shift in cognition toward more technical aspects of motor performance was strongly related to scores on the Decision Specific Reinvestment Scale, suggesting individuals with a higher propensity for reinvestment show the largest changes in cognition under pressure. From a practical perspective, TA can aid a player, coach or sport psychologist by allowing thought processes to be identified and investigate a performer’s thoughts when faced with the pressure of a competition.

    The mental control of mood and mood-related thought was investigated. In Experiment 1, Ss reminiscing about a happy or sad event were asked to make their mood positive, were given no instructions, or were asked to make their mood negative. Ss attempting mood control without an imposed cognitive load were successful, whereas those who attempted control while rehearsing a 9-digit number not only failed to control their moods but also showed self-reported mood change opposite the mood they intended to create. In Experiment 2, Ss attempting to control mood-related thoughts under cognitive load showed increased accessibility of those thoughts contrary to the direction of intended control in a Stroop-type color-naming task.

    2016-06-01

    Reflection positivity originates from one of the Osterwalder-Schrader axioms for constructive quantum field theory. It serves as a bridge between euclidean and relativistic quantum field theory. In mathematics, more specifically, in representation theory, it is related to the Cartan duality of symmetric Lie groups (Lie groups with an involution) and results in a transformation of a unitary representation of a symmetric Lie group to a unitary representation of its Cartan dual. In this article we continue our investigation of representation theoretic aspects of reflection positivity by discussing reflection positive Markov processes indexed by Lie groups, measures on path spaces, and invariant gaussian measures in spaces of distribution vectors. This provides new constructions of reflection positive unitary representations.

    Within Deaf classrooms there is often a disconnect between academic areas and writing curriculums that develop in both common and academic language, where often classrooms focus solely on writing as a skill rather than as a method for producing language through an academic area. This work focuses on the development of academic language in ASL and English print of science. The curriculum is written to be implemented as a bilingual academic curriculum to support Deaf and Hard of Hearing students in various self contained classroom settings. Lessons are conducted in three Units, A B and C. Unit A focuses on research, thought and writing of preparatory materials in small groups. Unit B is comprised of procedural lessons on conducting x experiments and the evaluation of those experiments through mathematics. Unit C is a group of lessons that ties together Units A and B through writing and peer teaching as a method of concluding the work and presenting information in an effective manner. The success of the project was evaluated on the basis of student work, rubrics, and final works from the students. The results showed promise in aspects of Critical Thinking, writing development, and expression of new concepts in both ASL and English.

    2013-01-15

    The ability to comprehend and represent the temporal properties of an occurrence is a crucial aspect of human language and cognition. Despite advances in neurolinguistic research into semantic processing, surprisingly little is known regarding the mechanisms which support the comprehension of temporal semantics. We used fMRI to investigate neural activity associated with processing of concrete and abstract sentences across the three temporal categories: past, present, and future. Theories of embodied cognition predict that concreteness-related activity would be evident in sensory and motor areas regardless of tense. Contrastingly, relying upon construal level theory we hypothesized that: (1) the neural markers associated with concrete language processing would appear for past and present tense sentences, but not for future sentences; (2) future tense sentences would activate intention-processing areas. Consistent with our first prediction, the results showed that activation in the parahippocampal gyrus differentiated between concrete and abstract sentences for past and present tense sentences, but not for future sentences. Not consistent with our second prediction, future tense sentences did not activate most of the regions that are implicated in the processing of intentions, but only activated the vmPFC. We discuss the implications of the current results to theories of embodied cognition and tense semantics. Copyright © 2012 Elsevier Inc. All rights reserved.

    A growing number of nurses are concerned with / participate in public affairs, politics, and policymaking processes. In particular, nursing leaders are actively leveraging their collective power to create interdisciplinary alliances aimed at encouraging the media and government to confront key nursing issues and implement healthcare reform. This article highlights the political participation and policy-making process to address the meaning and essence of politics, politics and nursing, training and strategies of public affairs and political participation, the shift from academia to health policy, and facilitation of important health policies. It is hoped that nurses may appropriately use their status and influence to actively participate in political campaigns and the policymaking process. By using their professional knowledge and skills, nurses may not only protect patient safety and public health but also facilitate nursing professional development and promote the professional image of nursing.

  13. A dual-process model of defense against conscious and unconscious death-related thoughts: an extension of terror management theory.

    Science.gov (United States)

    Pyszczynski, T; Greenberg, J; Solomon, S

    1999-10-01

    Distinct defensive processes are activated by conscious and nonconscious but accessible thoughts of death. Proximal defenses, which entail suppressing death-related thoughts or pushing the problem of death into the distant future by denying one's vulnerability, are rational, threat-focused, and activated when thoughts of death are in current focal attention. Distal terror management defenses, which entail maintaining self-esteem and faith in one's cultural worldview, function to control the potential for anxiety that results from knowing that death is inevitable. These defenses are experiential, are not related to the problem of death in any semantic or logical way, and are increasingly activated as the accessibility of death-related thoughts increases, up to the point at which such thoughts enter consciousness and proximal threat-focused defenses are initiated. Experimental evidence for this analysis is presented.

    Full Text Available Patricia Waugh defined metafiction as ‘fictional writing which self-consciously and systematically draws attention to its status as an artefact in order to pose questions about the relationship between fiction and reality’ . Metafictional works, she suggested, are those which ‘explore a theory of writing fiction through the practice of writing fiction’. They are characterised by a tendency to self-reflexivity or, in other words, by a tendency to call attention to the writing process itself. In actual fact, even in dedicated critical works, it is not easy to find a clear and all-encompassing definition of metafiction. Generally, various types of texts are mentioned under this term: texts recounting their origin and birth, dealing with the history of narrative, recounting stories of writers. Metafiction is generally considered an important feature of postmodern literature. In the postmodern era pure realistic writing is perceived as a limitation and an unsuitable device to render the complexity of the contemporary world. As Baudrillard said, we no longer live in a world made of unequivocal meanings, we live in a world of signs. In this context authors, by reflecting on the writing process, foreground the fictional nature of their narratives. Because of this, the role of metafiction (which obviously cannot be considered as an innovation introduced by postmodernism has become predominant in the postmodern era. Metafiction can follow different paths to reach its aims: its experimental component can be evident and radical or can be limited to a few pages or lines, without unduly affecting the perception of the story. In some cases, the reader will find no reflections on the structure or on the textual functions of the novel, but on its artistic and intellectual meaning. Within the history of Hindi literature (referring here to Khari Boli Hindi only probably the most famous example of metafictional novel is Suraj ka Satvan Ghoda (The Sun

I had planned to write the first draft the evening after my clinic on Tuesday, September 11. It didn't get done that night or during the next week. Somehow, the topic that I had originally chosen just didn't seem that important anymore as I, along my friends and colleagues, reflected on the changes that the events of that day were likely to have on our lives.

  18. Third thoughts

    CERN Document Server

    Weinberg, Steven

    2018-01-01

    A wise, personal, and wide-ranging meditation on science and society by the Nobel Prize–winning author of To Explain the World. For more than four decades, one of the most captivating and celebrated science communicators of our time has challenged the public to think carefully about the foundations of nature and the inseparable entanglement of science and society. In Third Thoughts Steven Weinberg casts a wide net: from the cosmological to the personal, from astronomy, quantum mechanics, and the history of science to the limitations of current knowledge, the art of discovery, and the rewards of getting things wrong. Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls, or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public...

    1980-01-01

    The Magicote C process developed by S.M. Thompsen was evaluated for use in applying an antireflective coating to the cover plates of solar panels. The process uses a fluosilicic acid solution supersaturated with silica at elevated temperature to selectively attack the surface of soda-lime glass cover plates and alter the physical and chemical composition of a thin layer of glass. The altered glass layer constitutes an antireflective coating. The process produces coatings of excellent optical quality which possess outstanding resistance to soiling and staining. The coatings produced are not resistant to mechanical abrasion and are attacked to some extent by glass cleansers. Control of the filming process was found to be difficult.

    Recent research demonstrated structural overlap between reward and self processing, but the functional relationship that explains how self processing influences reward processing remains unclear. The present study used an experimentally constrained reflection task to investigate whether individuals' outcome evaluations in a gambling task are modulated by task-unrelated self- and other-reflection processes. The self- and other-reflection task contained descriptions of the self or others, and brain event-related potentials (ERPs) were recorded while 16 normal adults performed a gambling task. The ERP analysis focused on the feedback-related negativity (FRN) component. We found that the difference wave of FRN increased in the self-reflection condition compared with the other-reflection condition. The present findings provide direct evidence that self processing can influence reward processing. Copyright © 2015 Elsevier B.V. All rights reserved.

  4. Beauty Requires Thought.

    Brielmann, Aenne A; Pelli, Denis G

    2017-05-22

    The experience of beauty is a pleasure, but common sense and philosophy suggest that feeling beauty differs from sensuous pleasures such as eating or sex. Immanuel Kant [1, 2] claimed that experiencing beauty requires thought but that sensuous pleasure can be enjoyed without thought and cannot be beautiful. These venerable hypotheses persist in models of aesthetic processing [3-7] but have never been tested. Here, participants continuously rated the pleasure felt from a nominally beautiful or non-beautiful stimulus and then judged whether they had experienced beauty. The stimuli, which engage various senses, included seeing images, tasting candy, and touching a teddy bear. The observer reported the feelings that the stimulus evoked. The time course of pleasure, across stimuli, is well-fit by a model with one free parameter: pleasure amplitude. Pleasure amplitude increases linearly with the feeling of beauty. To test Kant's claim of a need for thought, we reduce cognitive capacity by adding a "two-back" task to distract the observer's thoughts. The distraction greatly reduces the beauty and pleasure experienced from stimuli that otherwise produce strong pleasure and spares that of less-pleasant stimuli. We also find that strong pleasure is always beautiful, whether produced reliably by beautiful stimuli or just occasionally by sensuous stimuli. In sum, we confirm Kant's claim that only the pleasure associated with feeling beauty requires thought and disprove his claim that sensuous pleasures cannot be beautiful.

    The development of cancer drugs is time-consuming and expensive. In particular, failures in late-stage clinical trials are a major cost driver for pharmaceutical companies. This puts a high demand on methods that provide insights into the success chances of new potential medicines. In this study, we systematically analyze publication patterns emerging along the drug discovery process of targeted cancer therapies, starting from basic research to drug approval - or failure. We find clear differences in the patterns of approved drugs compared with those that failed in Phase II/III. Feeding these features into a machine learning classifier allows us to predict the approval or failure of a targeted cancer drug significantly better than educated guessing. We believe that these findings could lead to novel measures for supporting decision making in drug development. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Canal, Margarita

    In her doctoral thesis, Margarita Canal explores the value of self-reflection to facilitate the learning process of collaborative negotiation skills as well as how self-reflection as a mental capacity functions. She draws on theories of self-reflection from the higher and management education...... that reflection makes learning evident to both teachers and students. Moreover, the research sheds light on the understanding of reflection as a mental capacity, based on the conceptualization of the six psychic characteristics connected to it, namely: 1) making contact with oneself, 2) connecting to others, 3......) reality perspective, 4) understanding and expressing emotions, 5) balanced narcissism, and 6) change process. This knowledge constitutes a contribution that allows management teachers who use journaling, self-reflection, or learning portfolios to take into account students’ psychic characteristics...

  9. Reflective processes of practitioners in head and neck cancer rehabilitation: a grounded theory study.

    Caty, Marie-Ève; Kinsella, Elizabeth Anne; Doyle, Philip C

    2016-12-01

    This study systematically examined how experienced Speech-Language Pathologists (SLPs) use the processes of reflection to develop knowledge relevant for practice in the context of head and neck cancer (HNC) rehabilitation. In-depth, semi-structured interviews were conducted with 12 SLPs working in HNC rehabilitation in North America. Grounded theory methodology was adopted for data collection and analysis. The findings inform a preliminary reflective practice model that depicts the processes of reflection used by practitioners interviewed. Nine categories of reflective processes were identified by participant SLPs in terms of the processes of reflection: ongoing questioning, experimenting through trial and error, integrating knowledge from past cases, embracing surprise, thinking out of the box, being in the moment, consulting with colleagues, putting oneself in the patients' shoes, and discerning ethical issues. These findings provide empirical evidence that supports Schön's theory of reflective practice and contribute to knowledge about the ways in which SLPs use processes of reflection in the context of HNC rehabilitation. The findings of this study have implications for how SLPs perceive and consider their role as knowledge-users and knowledge producers in their day-to-day clinical work, as well as for building capacity for reflective practice.

  10. From intrusive to oscillating thoughts.

    Science.gov (United States)

    Peirce, Anne Griswold

    2007-10-01

    This paper focused on the possibility that intrusive thoughts (ITs) are a form of an evolutionary, adaptive, and complex strategy to prepare for and resolve stressful life events through schema formation. Intrusive thoughts have been studied in relation to individual conditions, such as traumatic stress disorder and obsessive-compulsive disorder. They have also been documented in the average person experiencing everyday stress. In many descriptions of thought intrusion, it is accompanied by thought suppression. Several theories have been put forth to describe ITs, although none provides a satisfactory explanation as to whether ITs are a normal process, a normal process gone astray, or a sign of pathology. There is also no consistent view of the role that thought suppression plays in the process. I propose that thought intrusion and thought suppression may be better understood by examining them together as a complex and adaptive mechanism capable of escalating in times of need. The ability of a biological mechanism to scale up in times of need is one hallmark of a complex and adaptive system. Other hallmarks of complexity, including self-similarity across scales, sensitivity to initial conditions, presence of feedback loops, and system oscillation, are also discussed in this article. Finally, I propose that thought intrusion and thought suppression are better described together as an oscillatory cycle.

    2010-01-01

    Full Text Available Founded on practical rationality, this qualitative case study aimed to explore the teaching practice at university, focusing on teacher's reflections and competencies. To this end, teaching practices were described, analyzed, and interpreted. These interactions with students on a course in the pharmacy program, brought about situations involving dilemmas and learning opportunities for problem-solving and decision-making skills. Throughout the study, students were encouraged to use knowledge-in-action, reflection-in-action, and reflection-on-action, and these processes were also experienced by the teacher. Analysis of the records from classroom observation and the interviews with students and the teacher showed the fundamental role of such reflective processes, which led to attainment of the intended objectives. In this sense, the teacher's reflective practice was essential for supporting the application of each curricular component of the course.

    2014-01-01

    Debates continue over shared factors in therapy processes between different theoretical orientations. By seeking the opinions of practicing clinicians, this study aimed to elucidate the similarities and differences between cognitive-behavioural (CBT), psychodynamic (PDT), and schema therapy (ST) approaches. Forty-eight practitioners aligning with one of the three approaches were asked to identify crucial processes in their therapy using a modified online version of the Psychotherapy Process Q-set. Distinct differences between each theoretical orientation with few shared common factors were found. A comparison with ratings from previous studies indicated that CBT therapists have not changed over the last 20 years, whereas PDT therapists have changed and the differences appeared consistent with modern PDT theory. The differences between the therapy approaches were consistent with theories underlying each model. PDT therapists valued a neutral relationship, CBT therapists emphasized a didactic interaction, and therapists form a ST orientation placed a greater emphasis on emotional involvement.

    A spectral image processing algorithm that allows the illumination of the scene with different illuminants together with the reconstruction of the scene's reflectance is presented. Color checker spectral image and CIE A (warm light 2700 K), D65 (cold light 6500 K) and Cree TW Series LED T8 (4000 K) are employed for scene illumination. Illuminants used in the simulations have different spectra and, as a result of their illumination, the colors of the scene change. The influence of the illuminants on the reconstruction of the scene's reflectance is estimated. Demonstrative images and reflectance showing the operation of the algorithm are illustrated.

  20. The Influence of Effortful Thought and Cognitive Proficiencies on the Conjunction Fallacy: Implications for Dual-Process Theories of Reasoning and Judgment.

    Science.gov (United States)

    Scherer, Laura D; Yates, J Frank; Baker, S Glenn; Valentine, Kathrene D

    2017-06-01

    Human judgment often violates normative standards, and virtually no judgment error has received as much attention as the conjunction fallacy. Judgment errors have historically served as evidence for dual-process theories of reasoning, insofar as these errors are assumed to arise from reliance on a fast and intuitive mental process, and are corrected via effortful deliberative reasoning. In the present research, three experiments tested the notion that conjunction errors are reduced by effortful thought. Predictions based on three different dual-process theory perspectives were tested: lax monitoring, override failure, and the Tripartite Model. Results indicated that participants higher in numeracy were less likely to make conjunction errors, but this association only emerged when participants engaged in two-sided reasoning, as opposed to one-sided or no reasoning. Confidence was higher for incorrect as opposed to correct judgments, suggesting that participants were unaware of their errors.

  5. Aging and repeated thought suppression success.

    Directory of Open Access Journals (Sweden)

    Ann E Lambert

    Full Text Available Intrusive thoughts and attempts to suppress them are common, but while suppression may be effective in the short-term, it can increase thought recurrence in the long-term. Because intentional suppression involves controlled processing, and many aspects of controlled processing decline with age, age differences in thought suppression outcomes may emerge, especially over repeated thought suppression attempts as cognitive resources are expended. Using multilevel modeling, we examined age differences in reactions to thought suppression attempts across four thought suppression sequences in 40 older and 42 younger adults. As expected, age differences were more prevalent during suppression than during free monitoring periods, with younger adults indicating longer, more frequent thought recurrences and greater suppression difficulty. Further, younger adults' thought suppression outcomes changed over time, while trajectories for older adults' were relatively stable. Results are discussed in terms of older adults' reduced thought recurrence, which was potentially afforded by age-related changes in reactive control and distractibility.

    2009-03-01

    Self-reflection is a tool of instruction that has been used in the science classroom. Research has shown great promise in using video as a learning tool in the classroom. However, the integration of self-reflective practice using video in the general chemistry laboratory to help students develop process skills has not been done. Immediate video feedback and direct instruction were employed in a general chemistry laboratory course to improve students' mastery and understanding of basic and advanced process skills. Qualitative results and statistical analysis of quantitative data proved that self-reflection significantly helped students develop basic and advanced process skills, yet did not seem to influence the general understanding of the science content.

    2013-05-01

    Learning circles are an enabling process to critically examine and reflect on practices with the purpose of promoting individual and organizational growth and change. The authors adapted and developed a learning circle strategy to facilitate open discourse between registered nurses, clinical leaders, clinical facilitators and students, to critically reflect on practice experiences to promote a positive learning environment. This paper reports on an analysis of field notes taken during a critical reflection process used to create an effective learning community in the workplace. A total of 19 learning circles were conducted during in-service periods (that is, the time allocated for professional education between morning and afternoon shifts) over a 3 month period with 56 nurses, 33 students and 1 university-employed clinical supervisor. Participation rates ranged from 3 to 12 individuals per discussion. Ten themes emerged from content analysis of the clinical learning issues identified through the four-step model of critical reflection used in learning circle discussions. The four-step model of critical reflection allowed participants to reflect on clinical learning issues, and raise them in a safe environment that enabled topics to be challenged and explored in a shared and cooperative manner.

    2014-05-01

    Full Text Available Background: Dual process models suggest that the development of addictive behaviors is the result of interplay between impulsive and reflective processes, modulated by boundary conditions such as individual or situational factors. Empirical support for this model has been repeatedly demonstrated in adult samples (for a meta-analysis see Rooke, Hine, & Thorsteinsson, 2008. The purpose of this study was to test these processes as they relate to emerging alcohol use in adolescents. Specifically, the interactive effects of several measures of impulsive and reflective processes and working memory capacity are examined as predictors of changes in alcohol use among adolescents. It was expected that measures of reflective processes would better predict changes in alcohol use than measures of impulsive processes. Moreover, it was anticipated that working memory capacity would moderate the relation between alcohol-specific impulsive and reflective processes and changes in adolescent alcohol use. Methods: The sample consisted of 427 adolescents (47.7% male between 12 and 16 years of age (M = 13.96, SD = .78 who reported drinking alcohol at least once. Four measures of impulsive processes were included. Attentional bias for alcohol was assessed with a Visual Probe Test; approach bias toward alcohol was assessed with a Stimulus Response Compatibility Test (SRC; and memory associations with alcohol were assessed with an Implicit Association Test (IAT and a Word Association Test (WAT. Two measures of reflective measures were included: positive and negative expectancies. Working memory capacity was measured using a Self-Ordered Pointing Task (SOPT.Results: Results showed that positive expectancies predicted changes in alcohol use, but this effect was qualified by an interaction with IAT scores. Moreover, SRC scores predicted changes in alcohol use only when negative expectancies were low. Attentional bias and word association scores did not predict changes in

However, it is not well investigated if and how explicitly these functions and the dynamics of a participatory process are reflected by modeling projects in particular. In this review study, I explore participatory modeling projects from a functional-dynamic process perspective. The main differences among projects relate to the functions of participation-most often, more than one per project can be identified, along with the degree of explicit reflection (i.e., awareness and anticipation) on the dynamic process perspective. Moreover, two main approaches are revealed: participatory modeling covering diverse approaches and companion modeling. It becomes apparent that the degree of reflection on the participatory process itself is not always explicit and perfectly visible in the descriptions of the modeling projects. Thus, the use of common protocols or templates is discussed to facilitate project planning, as well as the publication of project results. A generic template may help, not in providing details of a project or model development, but in explicitly reflecting on the participatory process. It can serve to systematize the particular project's approach to stakeholder collaboration, and thus quality management.

    Yeats, Rowena M; Yeats, Martyn F

    2007-11-01

    Resolution of a critical organizational problem requires the use of carefully selected techniques. This is the work of a management consultant: facilitating a business change process in an organizational setting. Here, an account is provided of a practitioner's reflections on one such case study that demonstrates a structure for a business change process. The reflective account highlights certain affective states and social behaviors that were extracted from participants during the business change process. These affective states and social behaviors are mediated by specific neural networks in the brain that are activated during organizational intervention. By breaking down the process into the affective states and social behaviors highlighted, cognitive neuroscience can be a useful tool for investigating the neural substrates of such intervention. By applying a cognitive neuroscience approach to examine organizational change, it is possible to converge on a greater understanding of the neural substrates of everyday social behavior.

  19. Seismic 2D reflection processing and interpretation of shallow refraction data

    Posiva Oy takes care of the final disposal of spent nuclear fuel in Finland. In year 2001 Olkiluoto was selected for the site of final disposal. Currently construction of the underground research facility, ONKALO, is going on at the Olkiluoto site. The aim of this work was to use two-dimensional reflection seismic processing methods to refraction seismic data collected from the ONKALO area in year 2002, and to locate gently dipping reflectors from the stacked sections. Processing was done using mainly open source software Seismic Unix. After the processing, the most distinct two-dimensional reflectors were picked from seismic sections using visualization environment OpendTect. After picking the features from crossing lines were combined into three-dimensional surfaces. Special attention was given for the detection of possible faults and discontinuities. The surfaces were given coordinates and their orientation was adjusted using a geometric procedure, which corresponds roughly a 3D migration, transferred to 3D presentation utility and compared to available geological information. The advantage of this work is to be able to get three-dimensional reflection seismic results from existing data set at only processing costs. Survey lines are also partly located in ONKALO area where extensive surface seismic surveys may not be possible to perform. The applied processing method was successful in detecting the reflectors. Most significant steps were the refraction and residual statics, and deconvolution. Some distinct reflectors can be seen at times 20-200 ms (vertical depths 50-500 m). The signal gets noisier below 200 ms. Reflectors are best visible as coherent phase between the adjacent traces, but do not raise much above the surrounding noise level. Higher amount of traces to be stacked would emphasis the reflections and their continuity more. Reflectors picked on crossing lines match well to borehole observations (KR4, KR7, KR24 and KR38) of fracture zones, and get

    Except in the specific case of end-of-life care, the law says nothing about the way in which health professionals must carry out ethical reflection regarding the treatment of their patients. A problem-solving methodology called the "ethical reflection approach" performed over several stages can be used. The decision-making process involves the whole team and draws on the ability of each caregiver to put forward a reasoned argument, in the interest of the patient.

    Beck extended his original cognitive theory of depression by suggesting that mania was a mirror image of depression characterized by extreme positive cognition about the self, the world, and the future. However, there were no suggestions what might be special regarding cognitive features in bipolar patients (Mansell & Scott, 2006). We therefore used different indicators to evaluate cognitive processes in bipolar patients and healthy controls. We compared 19 remitted bipolar I patients (BPs) without any Axis I comorbidity with 19 healthy individuals (CG). All participants completed the Beck Depression Inventory, the Dysfunctional Attitude Scale, the Automatic Thoughts Questionnaire, the Emotional Stroop Test, and an incidental recall task. No significant group differences were found in automatic thinking and the information-processing styles (Emotional Stroop Test, incidental recall task). Regarding dysfunctional attitudes, we obtained ambiguous results. It appears that individuals with remitted bipolar affective disorder do not show cognitive vulnerability as proposed in Beck's theory of depression if they only report subthreshold levels of depressive symptoms. Perhaps, the cognitive vulnerability might only be observable if mood induction procedures are used.

    Full Text Available Philosophy plays a key role in growth of sciences through the human history. Thought liberalizes within communities in which philosophy develops and enlightenment of the community gains acceleration. There are significant contributions in civilization by not only philosophy but also literary thought. In due course philosophic and literary understandings form a complementary structure. Naturally it has positive effect on science. The west substitutes rationalism rather than scholastic understanding. Rationalism accompanies enlightenment. Efficiency of the individual is improved during such period beginning with Descartes. In time, a need to philosophize appears in any person. Change of mentality within Turkish society appears following Tanzimat (reorganization of Ottoman Empire unlikely from western society. Change of mentality within Turkish society takes up a long time and is rough. For us, there is no experience of an “age of enlightenment” as in the west. Turkish intellectual realizes the change and transition occurring throughout the world as contacts with the west. The imperial edict of Gülhane (Tanzimat Fermanı is confronted us as an indication of that change and transition. In this study, relationship between philosophy and literature as well as reflections of positivist and materialist understandings to our culture in parallel to such relationship were sought to be evaluated.

  5. NONLINEAR REFLECTION PROCESS OF LINEARLY POLARIZED, BROADBAND ALFVÉN WAVES IN THE FAST SOLAR WIND

    Using one-dimensional numerical simulations, we study the elementary process of Alfvén wave reflection in a uniform medium, including nonlinear effects. In the linear regime, Alfvén wave reflection is triggered only by the inhomogeneity of the medium, whereas in the nonlinear regime, it can occur via nonlinear wave–wave interactions. Such nonlinear reflection (backscattering) is typified by decay instability. In most studies of decay instabilities, the initial condition has been a circularly polarized Alfvén wave. In this study we consider a linearly polarized Alfvén wave, which drives density fluctuations by its magnetic pressure force. For generality, we also assume a broadband wave with a red-noise spectrum. In the data analysis, we decompose the fluctuations into characteristic variables using local eigenvectors, thus revealing the behaviors of the individual modes. Different from the circular-polarization case, we find that the wave steepening produces a new energy channel from the parent Alfvén wave to the backscattered one. Such nonlinear reflection explains the observed increasing energy ratio of the sunward to the anti-sunward Alfvénic fluctuations in the solar wind with distance against the dynamical alignment effect.

  6. Visual Short-Term Memory Activity in Parietal Lobe Reflects Cognitive Processes beyond Attentional Selection.

    Visual short-term memory (VSTM) and attention are distinct yet interrelated processes. While both require selection of information across the visual field, memory additionally requires the maintenance of information across time and distraction. VSTM recruits areas within human (male and female) dorsal and ventral parietal cortex that are also implicated in spatial selection; therefore, it is important to determine whether overlapping activation might reflect shared attentional demands. Here, identical stimuli and controlled sustained attention across both tasks were used to ask whether fMRI signal amplitude, functional connectivity, and contralateral visual field bias reflect memory-specific task demands. While attention and VSTM activated similar cortical areas, BOLD amplitude and functional connectivity in parietal cortex differentiated the two tasks. Relative to attention, VSTM increased BOLD amplitude in dorsal parietal cortex and decreased BOLD amplitude in the angular gyrus. Additionally, the tasks differentially modulated parietal functional connectivity. Contrasting VSTM and attention, intraparietal sulcus (IPS) 1-2 were more strongly connected with anterior frontoparietal areas and more weakly connected with posterior regions. This divergence between tasks demonstrates that parietal activation reflects memory-specific functions and consequently modulates functional connectivity across the cortex. In contrast, both tasks demonstrated hemispheric asymmetries for spatial processing, exhibiting a stronger contralateral visual field bias in the left versus the right hemisphere across tasks, suggesting that asymmetries are characteristic of a shared selection process in IPS. These results demonstrate that parietal activity and patterns of functional connectivity distinguish VSTM from more general attention processes, establishing a central role of the parietal cortex in maintaining visual information. SIGNIFICANCE STATEMENT Visual short-term memory (VSTM) and

    A transmission and reflection coupled ultrasonic process tomography has been developed, which is characterized by a proposed dual-mode (DM) reconstruction algorithm, as well as an adaptive search approach to determine an optimal image threshold during the image binarization. In respect of hardware, to improve the accuracy of time-of-flight (TOF) and extend the lowest detection limit of particle size, a cylindrical miniaturized transducer using polyvinylidene fluoride (PVDF) films is designed. Besides, the development of range-gating technique for the identification of transmission and reflection waves in scanning is discussed. A particle system with four iron particles is then investigated numerically and experimentally to evaluate these proposed methods. The sound pressure distribution in imaging area is predicted numerically, followed by the analysis of the relationship between the emitting surface width of transducer and particle size. After the processing of experimental data for effective waveform extraction and fusion, the comparison between reconstructed results from transmission-mode (TM), reflection-mode (RM), and dual-mode reconstructions is carried out and the latter manifests obvious improvements from the blurring reduction to the enhancement of particle boundary.

    Attention-deficit/hyperactivity disorder (ADHD) is associated with performance deficits across a broad range of tasks. Although individual tasks are designed to tap specific cognitive functions (e.g., memory, inhibition, planning, etc.), these deficits could also reflect general effects related to either inefficient or impulsive information processing or both. These two components cannot be isolated from each other on the basis of classical analysis in which mean reaction time (RT) and mean accuracy are handled separately. Seventy children with a diagnosis of combined type ADHD and 50 healthy controls (between 6 and 17 years) performed two tasks: a simple two-choice RT (2-CRT) task and a conflict control task (CCT) that required higher levels of executive control. RT and errors were analyzed using the Ratcliff diffusion model, which divides decisional time into separate estimates of information processing efficiency (called "drift rate") and speed-accuracy tradeoff (SATO, called "boundary"). The model also provides an estimate of general nondecisional time. Results were the same for both tasks independent of executive load. ADHD was associated with lower drift rate and less nondecisional time. The groups did not differ in terms of boundary parameter estimates. RT and accuracy performance in ADHD appears to reflect inefficient rather than impulsive information processing, an effect independent of executive function load. The results are consistent with models in which basic information processing deficits make an important contribution to the ADHD cognitive phenotype.

    To describe the importance of supervisors working together in supporting the learning process of nurse students through reflective caring science supervision. A supervision model has been developed in order to meet the need for interweaving theory and practice. The model is characterized by learning reflection in caring science. A unique aspect of the present project was that the student groups were led by a teacher and a nurse. Data were collected through interviews with the supervisors. The analysis was performed with a phenomenological approach. The results showed that theory and practice can be made more tangible and interwoven by using two supervisors in a dual supervision. The essential structure is built on the constituents 'Reflection as Learning Support', 'Interweaving Caring Science with the Patient's Narrative', 'The Student as a Learning Subject' and 'The Learning Environment of Supervision'. The study concludes that supervision in pairs provides unique possibilities for interweaving and developing theory and practice. The supervision model offers unique opportunities for cooperation, for the development of theory and practice and for the development of the professional roll of nurses and teachers. © 2012 Blackwell Publishing Ltd.

  12. Hippocampal Theta-Gamma Coupling Reflects State-Dependent Information Processing in Decision Making.

    2018-03-20

    During decision making, hippocampal activity encodes information sometimes about present and sometimes about potential future plans. The mechanisms underlying this transition remain unknown. Building on the evidence that gamma oscillations at different frequencies (low gamma [LG], 30-55 Hz; high gamma [HG], 60-90 Hz; and epsilon, 100-140 Hz) reflect inputs from different circuits, we identified how changes in those frequencies reflect different information-processing states. Using a unique noradrenergic manipulation by clonidine, which shifted both neural representations and gamma states, we found that future representations depended on gamma components. These changes were identifiable on each cycle of theta as asymmetries in the theta cycle, which arose from changes within the ratio of LG and HG power and the underlying phases of those gamma rhythms within the theta cycle. These changes in asymmetry of the theta cycle reflected changes in representations of present and future on each theta cycle. Copyright © 2018 The Author(s). Published by Elsevier Inc.

  14. Popper's Thought Experiment Reinvestigated

    Science.gov (United States)

    Richardson, Chris; Dowling, Jonathan

    2012-02-01

    Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

    Controversy has attended the relationship between risk-adjusted mortality and process-of-care. There would be advantage in the establishment, at the data-base level, of global quantitative indices subsuming the diversity of process-of-care. A retrospective, cohort study of patients identified in the Australian and New Zealand Intensive Care Society Adult Patient Database, 1993-2003, at the level of geographic and ICU-level descriptors (n = 35), for both hospital survivors and non-survivors. Process-of-care indices were established by analysis of: (i) the smoothed time-hazard curve of individual patient discharge and determined by pharmaco-kinetic methods as area under the hazard-curve (AUC), reflecting the integrated experience of the discharge process, and time-to-peak-hazard (TMAX, in days), reflecting the time to maximum rate of hospital discharge; and (ii) individual patient ability to optimize output (as length-of-stay) for recorded data-base physiological inputs; estimated as a technical production-efficiency (TE, scaled [0,(maximum)1]), via the econometric technique of stochastic frontier analysis. For each descriptor, multivariate correlation-relationships between indices and summed mortality probability were determined. The data-set consisted of 223129 patients from 99 ICUs with mean (SD) age and APACHE III score of 59.2(18.9) years and 52.7(30.6) respectively; 41.7% were female and 45.7% were mechanically ventilated within the first 24 hours post-admission. For survivors, AUC was maximal in rural and for-profit ICUs, whereas TMAX (>or= 7.8 days) and TE (>or= 0.74) were maximal in tertiary-ICUs. For non-survivors, AUC was maximal in tertiary-ICUs, but TMAX (>or= 4.2 days) and TE (>or= 0.69) were maximal in for-profit ICUs. Across descriptors, significant differences in indices were demonstrated (analysis-of-variance, P variance, for survivors (0.89) and non-survivors (0.89), was maximized by combinations of indices demonstrating a low correlation with

    Full Text Available Objective. Activation of semantic networks is indexed by the N400 effect. We used a twin study design to investigate whether N400 effect abnormalities reflect genetic/trait liability or are related to psychopathological processes in schizophrenia. Methods. We employed robust linear regression to compare N400 and behavioral priming effects across 36 monozygotic twin pairs (6 pairs concordant for schizophrenia/schizoaffective disorder, 11 discordant pairs, and 19 healthy control pairs performing a lexical decision task. Moreover, we examined the correlation between Brief Psychiatric Rating Scale (BPRS score and the N400 effect and the influence of medication status on this effect. Results. Regression yielded a significant main effect of group on the N400 effect only in the direct priming condition (p=0.003. Indirect condition and behavioral priming effect showed no significant effect of group. Planned contrasts with the control group as a reference group revealed that affected concordant twins had significantly reduced N400 effect compared to controls, and discordant affected twins had a statistical trend for reduced N400 effect compared to controls. The unaffected twins did not differ significantly from the controls. There was a trend for correlation between reduced N400 effect and higher BPRS scores, and the N400 effect did not differ significantly between medicated and unmedicated patients. Conclusions. Reduced N400 effect may reflect disease-specific processes in schizophrenia implicating frontotemporal brain network in schizophrenia pathology.

  19. Acting in Good Time – Conceptual Reflections on the Sequencing of Political Reform Processes

    Directory of Open Access Journals (Sweden)

    Jürgen Beyer

    2012-12-01

    Full Text Available Thus far, the sequencing of political reform processes has been discussed on a separate basis in the context of different scientific debates. Existing analysis in macroeconomics and democracy theory focuses on shock-therapeutic versus gradual reform policies, the succession of specific reform steps or the right timing of reforms. An analytical approach to sequences has been elaborated. Theoretical concepts of social change, which refer to path dependence or the punctuated development of historical sequences, have evolved in the context of institutionalist research. The present article summarises the state of research and extends it with conceptual reflections on the motivation of sequential political action, which can then serve as a starting point for differentiation between sequencing processes in further research.

  4. On the origins of endogenous thoughts.

    Endogenous thoughts are thoughts that we activate in a top-down manner or in the absence of the appropriate stimuli. We use endogenous thoughts to plan or recall past events. In this sense, endogenous thinking is one of the hallmarks of our cognitive lives. In this paper, I investigate how it is that we come to possess endogenous control over our thoughts. Starting from the close relation between language and thinking, I look into speech production-a process motorically controlled by the inferior frontal gyrus (IFG). Interestingly, IFG is also closely related to silent talking, as well as volition. The connection between IFG and volition is important given that endogenous thoughts are or at least greatly resemble voluntary actions. Against this background, I argue that IFG is key to understanding the origins of conscious endogenous thoughts. Furthermore, I look into goal-directed thinking and show that IFG plays a key role also in unconscious endogenous thinking.

    Arweiler and Buchholz [J. Acoust. Soc. Am. 130, 996-1005 (2011)] showed that, while the energy of early reflections (ERs) in a room improves speech intelligibility, the benefit is smaller than that provided by the energy of the direct sound (DS). In terms of integration of ERs and DS, binaural...... listening did not provide a benefit from ERs apart from a binaural energy summation, such that monaural auditory processing could account for the data. However, a diffuse speech shaped noise (SSN) was used in the speech intelligibility experiments, which does not provide distinct binaural cues...... to the auditory system. In the present study, the monaural and binaural benefit from ERs for speech intelligibility was investigated using three directional maskers presented from 90° azimuth: a SSN, a multi-talker babble, and a reversed two-talker masker.

    1994-01-01

    An apparatus and process are disclosed for removal of a stripe of soft reflective material of uniform width from the surface of a mirror by using a blade having a large included angle to inhibit curling of the blade during the cutting operation which could result in damage to the glass substrate of the mirror. The cutting blade is maintained at a low blade angle with respect to the mirror surface to produce minimal chipping along the cut edge and to minimize the force exerted on the coating normal to the glass surface which could deform the flat mirror. The mirror is mounted in a cutting mechanism containing a movable carriage on which the blade is mounted to provide very accurate straightness of the travel of the blade along the mirror.

    Nursing students on clinical placements as part of their professional training are routinely faced with situations involving ethical conflicts. The initial act of perceiving a situation as causing an ethical dilemma is the result of both the students' personal values, drawn from their culture and families, and of the professional knowledge and values that they have acquired through training and experience. Nursing students' experiences on clinical placements in primary care settings were investigated in order to identify situations that they perceived as involving ethical conflict and describe the elements they took into consideration during their decision-making processes in these situations. The research design was qualitative descriptive case study. Around 50 students from three different intakes to a nursing degree answered a questionnaire and discussed it in focus groups. The study was designed in accordance with the principles guiding research with human beings and was approved by the Human Research Ethics Committee. Synthesised into two principal axes: (a) ethical conflicts in primary care, linked with the domains of working processes, professional nursing ethics and human and social rights and (b) students' decision-making processes - realisation, reflection and intervention. The student nurses saw themselves both as actors and spectators in situations involving ethical problems and demanding moral deliberation, demonstrating the ability to base their arguments soundly. They tended to emphasise the possibilities offered by dialogue and that different ethical values must be respected to find fair solutions to ethical problems. © The Author(s) 2014.

    Modern bioprocesses demand for a careful definition of the critical process parameters (CPPs) already during the early stages of process development in order to ensure high-quality products and satisfactory yields. In this context, online monitoring tools can be applied to recognize unfavorable changes of CPPs during the production processes and to allow for early interventions in order to prevent losses of production batches due to quality issues. Process analytical technologies such as the dielectric spectroscopy or focused beam reflectance measurement (FBRM) are possible online monitoring tools, which can be applied to monitor cell growth as well as morphological changes. Since the dielectric spectroscopy only captures cells with intact cell membranes, even information about dead cells with ruptured or leaking cell membranes can be derived. The following chapter describes the application of dielectric spectroscopy on various virus-infected and non-infected cell lines with respect to adherent as well as suspension cultures in common stirred tank reactors. The adherent mammalian cell lines Vero (African green monkey kidney cells) and hMSC-TERT (telomerase-immortalized human mesenchymal stem cells) are thereby cultured on microcarrier, which provide the required growth surface and allow the cultivation of these cells even in dynamic culture systems. In turn, the insect-derived cell lines S2 and Sf21 are used as examples for cells typically cultured in suspension. Moreover, the FBRM technology as a further monitoring tool for cell culture applications has been included in this chapter using the example of Drosophila S2 insect cells.

    Researchers and quality improvement advocates sometimes use review of chart-documented pain care processes to assess the quality of pain management. Studies have found that primary care providers frequently fail to document pain assessment and management. To assess documentation of pain care processes in an academic primary care clinic and evaluate the validity of this documentation as a measure of pain care delivered. Prospective observational study. 237 adult patients at a university-affiliated internal medicine clinic who reported any pain in the last week. Immediately after a visit, we asked patients to report the pain treatment they received. Patients completed the Brief Pain Inventory (BPI) to assess pain severity at baseline and 1 month later. We extracted documentation of pain care processes from the medical record and used kappa statistics to assess agreement between documentation and patient report of pain treatment. Using multivariable linear regression, we modeled whether documented or patient-reported pain care predicted change in pain at 1 month. Participants' mean age was 53.7 years, 66% were female, and 74% had chronic pain. Physicians documented pain assessment for 83% of visits. Patients reported receiving pain treatment more often (67%) than was documented by physicians (54%). Agreement between documentation and patient report was moderate for receiving a new pain medication (k = 0.50) and slight for receiving pain management advice (k = 0.13). In multivariable models, documentation of new pain treatment was not associated with change in pain (p = 0.134). In contrast, patient-reported receipt of new pain treatment predicted pain improvement (p = 0.005). Chart documentation underestimated pain care delivered, compared with patient report. Documented pain care processes had no relationship with pain outcomes at 1 month, but patient report of receiving care predicted clinically significant improvement. Chart review measures may not accurately

  16. Separation of irradiance and reflectance from observed color images by logarithmical nonlinear diffusion process

    Science.gov (United States)

    Saito, Takahiro; Takahashi, Hiromi; Komatsu, Takashi

    2006-02-01

    The Retinex theory was first proposed by Land, and deals with separation of irradiance from reflectance in an observed image. The separation problem is an ill-posed problem. Land and others proposed various Retinex separation algorithms. Recently, Kimmel and others proposed a variational framework that unifies the previous Retinex algorithms such as the Poisson-equation-type Retinex algorithms developed by Horn and others, and presented a Retinex separation algorithm with the time-evolution of a linear diffusion process. However, the Kimmel's separation algorithm cannot achieve physically rational separation, if true irradiance varies among color channels. To cope with this problem, we introduce a nonlinear diffusion process into the time-evolution. Moreover, as to its extension to color images, we present two approaches to treat color channels: the independent approach to treat each color channel separately and the collective approach to treat all color channels collectively. The latter approach outperforms the former. Furthermore, we apply our separation algorithm to a high quality chroma key in which before combining a foreground frame and a background frame into an output image a color of each pixel in the foreground frame are spatially adaptively corrected through transformation of the separated irradiance. Experiments demonstrate superiority of our separation algorithm over the Kimmel's separation algorithm.

  17. Big-data reflection high energy electron diffraction analysis for understanding epitaxial film growth processes.

    Vasudevan, Rama K; Tselev, Alexander; Baddorf, Arthur P; Kalinin, Sergei V

    2014-10-28

    Reflection high energy electron diffraction (RHEED) has by now become a standard tool for in situ monitoring of film growth by pulsed laser deposition and molecular beam epitaxy. Yet despite the widespread adoption and wealth of information in RHEED images, most applications are limited to observing intensity oscillations of the specular spot, and much additional information on growth is discarded. With ease of data acquisition and increased computation speeds, statistical methods to rapidly mine the data set are now feasible. Here, we develop such an approach to the analysis of the fundamental growth processes through multivariate statistical analysis of a RHEED image sequence. This approach is illustrated for growth of La(x)Ca(1-x)MnO(3) films grown on etched (001) SrTiO(3) substrates, but is universal. The multivariate methods including principal component analysis and k-means clustering provide insight into the relevant behaviors, the timing and nature of a disordered to ordered growth change, and highlight statistically significant patterns. Fourier analysis yields the harmonic components of the signal and allows separation of the relevant components and baselines, isolating the asymmetric nature of the step density function and the transmission spots from the imperfect layer-by-layer (LBL) growth. These studies show the promise of big data approaches to obtaining more insight into film properties during and after epitaxial film growth. Furthermore, these studies open the pathway to use forward prediction methods to potentially allow significantly more control over growth process and hence final film quality.

    The results of the investigation of the inelastic interaction of 300-3000 eV electrons with the Ni and Au surfaces by the analysis of absolute reflection electron energy loss spectroscopy (REELS) spectra were described. The present analysis enables the inelastic mean free path (IMFP), surface excitation parameter (SEP) and differential SEP (DSEP) to be obtained simultaneously from an absolute REELS spectrum. The obtained IMFPs for Ni and Au showed a good agreement with those calculated using the TPP-2M predictive equation. The present SEPs determined for Ni and Au were fitted to the Chen's formula describing the dependence of the SEP on the electron energy, and material parameters for Ni and Au in Chen's formula were proposed. The present DESPs were compared with the theoretical results, and a reasonable agreement between the experimentally determined DSEPs and theoretical results was confirmed. The MC modeling of calculating the REELS spectrum, in which energy loss processes due to surface excitations are taken into account, was also described. The IMFP, SEP and DSEP determined by the present absolute REELS analysis were employed to describe energy loss processes by inelastic scattering in the proposed MC simulation. The simulated REELS spectra were found to be in a good agreement with the experimental spectra for both Ni and Au.

  19. Solution-processable MoOx nanocrystals enable highly efficient reflective and semitransparent polymer solar cells

    KAUST Repository

    Jagadamma, Lethy Krishnan

    2016-09-09

    Solution-manufacturing of organic solar cells with best-in-class power conversion efficiency (PCE) will require all layers to be solution-coated without compromising solar cell performance. To date, the hole transporting layer (HTL) deposited on top of the organic bulk heterojunction layer in the inverted architecture is most commonly an ultrathin (<10 nm) metal oxide layer prepared by vacuum-deposition. Here, we show that an alcohol-based nanocrystalline MoOx suspension with carefully controlled nanocrystal (NC) size can yield state of the art reflective and semitransparent solar cells. Using NCs smaller than the target HTL thickness (∼10 nm) can yield compact, pinhole-free films which result in highly efficient polymer:fullerene bulk heterojunction (BHJ) solar cells with PCE=9.5%. The solution processed HTL is shown to achieve performance parity with vacuum-evaporated HTLs for several polymer:fullerene combinations and is even shown to work as hole injection layer in polymer light emitting diodes (PLED). We also demonstrate that larger MoOx NCs (30–50 nm) successfully composite MoOx with Ag nanowires (NW) to form a highly conducting, transparent top anode with exceptional contact properties. This yields state-of-the-art semitransparent polymer: fullerene solar cells with PCE of 6.5% and overall transmission >30%. The remarkable performance of reflective and semitransparent OPVs is due to the uncommonly high fill factors achieved using a carefully designed strategy for implementation of MoOx nanocrystals as HTL materials. © 2016 Elsevier Ltd

  20. Brain reflections: A circuit-based framework for understanding information processing and cognitive control.

    Science.gov (United States)

    Gratton, Gabriele

    2018-03-01

    Here, I propose a view of the architecture of the human information processing system, and of how it can be adapted to changing task demands (which is the hallmark of cognitive control). This view is informed by an interpretation of brain activity as reflecting the excitability level of neural representations, encoding not only stimuli and temporal contexts, but also action plans and task goals. The proposed cognitive architecture includes three types of circuits: open circuits, involved in feed-forward processing such as that connecting stimuli with responses and characterized by brief, transient brain activity; and two types of closed circuits, positive feedback circuits (characterized by sustained, high-frequency oscillatory activity), which help select and maintain representations, and negative feedback circuits (characterized by brief, low-frequency oscillatory bursts), which are instead associated with changes in representations. Feed-forward activity is primarily responsible for the spread of activation along the information processing system. Oscillatory activity, instead, controls this spread. Sustained oscillatory activity due to both local cortical circuits (gamma) and longer corticothalamic circuits (alpha and beta) allows for the selection of individuated representations. Through the interaction of these circuits, it also allows for the preservation of representations across different temporal spans (sensory and working memory) and their spread across the brain. In contrast, brief bursts of oscillatory activity, generated by novel and/or conflicting information, lead to the interruption of sustained oscillatory activity and promote the generation of new representations. I discuss how this framework can account for a number of psychological and behavioral phenomena. © 2017 Society for Psychophysiological Research.

  1. Virtual logistics as a support for decomposition process of supply chain (conceptual reflections

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Background: Traditionally the concept of the "supply chain" is connected with various forms of the technical, organizational and economic integration. The integration deals mainly with multilateral relations among firms, thus constituting subsequent links of products flows in supply chains and creating complex networks of business connections. Due to social and economic factors, and mainly outsourcing and resulting accent on logistics services, traditional supply chains become decomposed. Therefore, there is a need to reconsider some concepts connected with this process. Methods: The description and analysis of present and decomposing supply chains were presented and discussed. The analysis of reasons and possibilities to give up the processes of the absolute integration of supply chains in the direction of decomposed structures and the indication of possibilities to use the concept of a virtual logistics as a concept, which allows essentially such actions, was conducted. Results: The disintegration of traditional value chains is one of these kinds' concepts, which are reflected also in classic supply chains. Probably the commonly used methods of the research and analysis of these supply chains do not conduce to make decisions under conditions of the lack of the continuity of business processes. Old methods and techniques of the management do not fit fully to modern business requirements, which are probably not even fully highlighted and properly understood. Conclusions: The saturation of modern supply chains with services caused significant modifications of the logic and many mechanisms of their functioning, which in turn can lead to changes of a paradigm of the management of these more and more complex business structures. The aspirations of companies to achieve the competitive advantage on modern markets help to change the structure and the nature of supply chains, which operate on these markets, in the direction of their virtualization.

  5. Thinking and writing at Masters level: a reflective passage.

    Science.gov (United States)

    Fowler, John

    This article identifies key characteristics of Masters level writing and the underpinning relationship of these characteristics to reflective thought. Classical models of reflective writing are reviewed and their focus on reflection as a progressive process is debated. A linear model of reflection is proposed and its application to reflective writing for Masters level assessments is examined. The classical authors tend to present reflection as a process in which the outcomes of reflection becomes deeper at advanced levels. While this is an appropriate application of the concept of reflection for the traditional academic essay, it might not always be so appropriate for other more applied aspects of thinking and writing particularly in the development of advanced nursing practice. A linear model of reflective writing which offers a more pragmatic perspective on reflection is developed.

    Diagnostic decision-making is made through a combination of Systems 1 (intuition or pattern-recognition) and Systems 2 (analytic) thinking. The purpose of this study was to use the Cognitive Reflection Test (CRT) to evaluate and compare the level of Systems 1 and 2 thinking among medical students in pre-clinical and clinical programs. The CRT is a three-question test designed to measure the ability of respondents to activate metacognitive processes and switch to System 2 (analytic) thinking where System 1 (intuitive) thinking would lead them astray. Each CRT question has a correct analytical (System 2) answer and an incorrect intuitive (System 1) answer. A group of medical students in Years 2 & 3 (pre-clinical) and Years 4 (in clinical practice) of a 5-year medical degree were studied. Ten percent (13/128) of students had the intuitive answers to the three questions (suggesting they generally relied on System 1 thinking) while almost half (44%) answered all three correctly (indicating full analytical, System 2 thinking). Only 3-13% had incorrect answers (i.e. that were neither the analytical nor the intuitive responses). Non-native English speaking students (n = 11) had a lower mean number of correct answers compared to native English speakers (n = 117: 1.0 s 2.12 respectfully: p System 2 answers increased and the percentage of intuitive answers decreased in both the pre-clinical and clinical students. Up to half of the medical students demonstrated full or partial reliance on System 1 (intuitive) thinking in response to these analytical questions. While their CRT performance has no claims to make as to their future expertise as clinicians, the test may be used in helping students to understand the importance of awareness and regulation of their thinking processes in clinical practice.

    First, I would bike to thank ENRESA and the Municipality for the work in organizing this workshop. The visit to the Vandellos power station and the economic development zone, combined with the speeches, lectures, and discussions we have had here at L'Hospitalet have offered a well-rounded perspective on the inclusion of stakeholders in decision making. Even more important was that the atmosphere of the meetings was conducive to an honest and open exchange of ideas. The structure of the workshop offered ample opportunities for people to talk and listen to each other. On the whole, I believe the workshop established a learning atmosphere. In response to my charge as a rapporteur, I have endeavored to he inquisitive and to explore explanations and interpretations that may be different - although not necessarily contradictory - to those offered outright. I have been asked to participate and observe during the course of this workshop and also to comment from the perspective of a scholar who does research in the area of stakeholder involvement. I have arranged my comments as follows. First, I present some recent findings from the literature on public participation in environmental policy and decision-making. I have elected to focus on 'criteria for success'. Second, I examine the strengths of the AMA-led COWAM-2 process emerging in Spain now in the context of these criteria for success. Finally, I reflect on some of the possible shortcomings that may loom on the horizon in order to alert process planners to anticipate the unexpected. (author)

    Full Text Available Patricia L Hardré,1 Mikio Nihira,2 Edgar L LeClaire3 1Department of Educational Psychology, University of Oklahoma College of Education, Norman, 2Department of Obstetrics and Gynecology, University of Oklahoma College of Medicine, Oklahoma City, OK, 3Department of Obstetrics and Gynecology, University of Kansas College of Medicine, Kansas City, KS, USA Abstract: Research in medical education does not provide a clear understanding of how professional expertise develops among surgeons and what experiential factors contribute to that development. To address this gap, the researchers interviewed 16 international experts in female pelvic medicine and reconstructive surgery to assess their reflective perceptions of what specific opportunities and experiences initiated and supported their development toward expertise in their field. Characteristics and influences explaining the speed and quality of expertise development were sorted into the following themes: the dynamic process of expertise development, internal and personal characteristics, general aptitudes and preparatory skills, role modeling and interpersonal influences, opportunities to learn and practice, and roles and reference points. Across the narratives and perspectives of these expert surgeons, both individual characteristics and choices, and contextual activities and opportunities were necessary and important. Experiences with greatest impact on quality of expertise development included those provided by the environment and mentors, as well as those sought out by learners themselves, to elaborate and supplement existing opportunities. The ideal combination across experts was interaction and integration of individual characteristics with experiential opportunities. Grounded in theory and research in expertise development, these findings can support improvement of medical education, both for individual mentors and strategic program development. As surgery evolves at a continuously

    Face recognition by normal subjects depends in roughly equal proportions on shape and surface reflectance cues, while object recognition depends predominantly on shape cues. It is possible that developmental prosopagnosics are deficient not in their ability to recognize faces per se, but rather in their ability to use reflectance cues. Similarly, super-recognizers' exceptional ability with face recognition may be a result of superior surface reflectance perception and memory. We tested this possibility by administering tests of face perception and face recognition in which only shape or reflectance cues are available to developmental prosopagnosics, super-recognizers, and control subjects. Face recognition ability and the relative use of shape and pigmentation were unrelated in all the tests. Subjects who were better at using shape or reflectance cues were also better at using the other type of cue. These results do not support the proposal that variation in surface reflectance perception ability is the underlying cause of variation in face recognition ability. Instead, these findings support the idea that face recognition ability is related to neural circuits using representations that integrate shape and pigmentation information.

  13. Low-effort thought promotes political conservatism.

    2012-06-01

    The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants' endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. Together these data suggest that political conservatism may be a process consequence of low-effort thought; when effortful, deliberate thought is disengaged, endorsement of conservative ideology increases.

    2017-05-01

    Full Text Available Black coloured materials and consumer goods are known to be heating up more, because they absorb sun radiation more than light colours. This heating is a problem for the users for black automotive or motorcycle leathers and also for dark shoes and boots which are exposed to sun heat. Human vision system can distinguish visible colours between the wavelengths of 390-700 nm. So reflecting the sun radiation in the infrared area of radiation spectrum higher than 700nm, is a solution for heating problem without affecting the visible colour. For this reason IR reflective dyes and pigments are designed. A leading Leather Chemical Company has developed an IR reflecting dyeing system for leather keeping the dark coloured leathers cooler under sun radiation. Additionally in theory, fat and water content of leather affects its heating properties. In this study, effect of natural, synthetic and waterproof fatliquoring systems on heating properties of leathers coloured with IR reflective dyes and pigments are investigated.

    Jones, Jeannie

    This is a reflective account of an ethical dilemma encountered while on placement on a cardiology ward. Reflection is a process which allows practitioners to reveal and expose thoughts, behaviours and feelings that are present at a particular time. All reflective models are based on the principle that purposeful reflection results in a better understanding and awareness, thus enhancing clinical practice (Driscoll and Teh 2001). The Gibbs' Reflective Cycle has been selected for its simplicity and ease of use to aid personal development. The dilemma was identified and analysed from a professional, ethical and legal perspective. Pseudonyms are used to maintain confidentiality and protect the identities of all parties involved.

    Steel tape scale grating of a reflective incremental linear encoder has a key impact on the measurement accuracy of the optical encoder. However, it is difficult for conventional manufacturing processes to fabricate scale grating with high-resolution grating strips, due to process and material problems. In this paper, self-assembly technology was employed to fabricate high-resolution steel tape scale grating for a reflective incremental linear encoder. Graphene oxide nanoparticles were adopted to form anti-reflective grating strips of steel tape scale grating. They were deposited in the tape, which had a hydrophobic and hydrophilic grating pattern when the dispersion of the nanoparticles evaporated. A standard lift-off process was employed to fabricate the hydrophobic grating strips on the steel tape. Simultaneously, the steel tape itself presents a hydrophilic property. The hydrophobic and hydrophilic grating pattern was thus obtained. In this study, octafluorocyclobutane was used to prepare the hydrophobic grating strips, due to its hydrophobic property. High-resolution graphene oxide steel tape scale grating with a pitch of 20 μ m was obtained through the self-assembly process. The photoelectric signals of the optical encoder containing the graphene oxide scale grating and conventional scale grating were tested under the same conditions. Comparison test results showed that the graphene oxide scale grating has a better performance in its amplitude and harmonic components than that of the conventional steel tape scale. A comparison experiment of position errors was also conducted, demonstrating an improvement in the positioning error of the graphene oxide scale grating. The comparison results demonstrated the applicability of the proposed self-assembly process to fabricate high-resolution graphene oxide scale grating for a reflective incremental linear encoder.

    Extracellular matrix (ECM) proteins, such as collagen type I and elastin, and intermediate filament (IMF) proteins, such as vimentin are modified and dysregulated as part of the malignant changes leading to disruption of tissue homeostasis. Noninvasive biomarkers that reflect such changes may have a great potential for cancer. Levels of matrix metalloproteinase (MMP) generated fragments of type I collagen (C1M), of elastin (ELM), and of citrullinated vimentin (VICM) were measured in serum from patients with lung cancer (n = 40), gastrointestinal cancer (n = 25), prostate cancer (n = 14), malignant melanoma (n = 7), chronic obstructive pulmonary disease (COPD) (n = 13), and idiopathic pulmonary fibrosis (IPF) (n = 10), as well as in age-matched controls (n = 33). The area under the receiver operating characteristics (AUROC) was calculated and a diagnostic decision tree generated from specific cutoff values. C1M and VICM were significantly elevated in lung cancer patients as compared with healthy controls (AUROC = 0.98, P < 0.0001) and other cancers (AUROC = 0.83 P < 0.0001). A trend was detected when comparing lung cancer with COPD+IPF. No difference could be seen for ELM. Interestingly, C1M and VICM were able to identify patients with lung cancer with a positive predictive value of 0.9 and an odds ratio of 40 (95% CI = 8.7–186, P < 0.0001). Biomarkers specifically reflecting degradation of collagen type I and citrullinated vimentin are applicable for lung cancer patients. Our data indicate that biomarkers reflecting ECM and IMF protein dysregulation are highly applicable in the lung cancer setting. We speculate that these markers may aid in diagnosing and characterizing patients with lung cancer

    2015-11-01

    The practice of community based participatory research (CBPR) has evolved over the past 20 years with the recognition that health equity is best achieved when academic researchers form collaborative partnerships with communities. This article theorizes the possibility that core principles of CBPR cannot be realistically applied unless unequal power relations are identified and addressed. It provides theoretical and empirical perspectives for understanding power, privilege, researcher identity and academic research team composition, and their effects on partnering processes and health disparity outcomes. The team's processes of conducting seven case studies of diverse partnerships in a national cross-site CBPR study are analyzed; the multi-disciplinary research team's self-reflections on identity and positionality are analyzed, privileging its combined racial, ethnic, and gendered life experiences, and integrating feminist and post-colonial theory into these reflections. Findings from the inquiry are shared, and incorporating academic researcher team identity is recommended as a core component of equalizing power distribution within CBPR.

    Mitchell, Neil C

    2012-12-13

    Much progress has been made in the UK in characterizing the internal structures of major physiographic features in the oceans and in developing understanding of the geological processes that have created or shaped them. UK researchers have authored articles of high impact in all areas described here. In contrast to terrestrial geoscience, however, there have been few instrumented observations made of active processes by UK scientists. This is an area that could be developed over the next decades in the UK. Research on active processes has the potential ability to engage the wider public: Some active processes present significant geo-hazards to populations and offshore infrastructure that require monitoring and there could be commercial applications of technological developments needed for science. Some of the suggestions could involve studies in shallow coastal waters where ship costs are much reduced, addressing tighter funding constraints over the near term. The possibilities of measuring aspects of volcanic eruptions, flowing lava, turbidity currents and mass movements (landslides) are discussed. A further area of potential development is in greater collaboration between the ocean sciences. For example, it is well known in terrestrial geomorphology that biological agents are important in modulating erosion and the transport of sediments, ultimately affecting the shape of the Earth's surface in various ways. The analogous effect of biology on large-scale geomorphology in the oceans is also known but remains poorly quantified. Physical oceanographic models are becoming increasingly accurate and could be used to study further the patterns of erosion, particle transport and deposition in the oceans. Marine geological and geophysical data could in turn be useful for further verification of such models. Adapting them to conditions of past oceans could address the shorter-period movements, such as due to internal waves and tides, which have been barely addressed in

    Klein, Stanley B

    2014-01-01

    In a recent paper Hart and Burns (2012) presented evidence that conditions that prime thoughts of one's mortality benefit recall. Drawing on the conceptual relation between thoughts of death and thoughts of survival, Hart and Burns interpret their findings as suggestive of the possibility that death-related thoughts function in manner similar to survival-related thoughts in enhancing recall. In the present study I draw on evolutionary arguments to question whether a conceptual relation between thoughts of death and thoughts of survival translates into a functional relation. I then present data showing that while death-related thoughts can promote high levels of recall, (a) the level achieved does not match that produced by survival processing and (b) survival and death cognition likely rely on different mechanisms to achieve their effects.

    2011-01-01

    This article investigates 2 possible antecedents of thought confidence and explores the effects of confidence induced before or during ad exposure. The results of the experiments indicate that both consumers' dispositional optimism and spokesperson attractiveness have significant effects on consumers' confidence in thoughts that are generated after viewing the advertisement. Higher levels of thought confidence will influence the quality of the thoughts that people generate, lead to either positively or negatively polarized message processing, and therefore induce better or worse advertising effectiveness, depending on the valence of thoughts. The authors posit the belief-polarization hypothesis to explain these findings.

    Pronin, Emily; Jacobs, Elana; Wegner, Daniel M

    2008-10-01

    Six experiments found that manipulations that increase thought speed also yield positive affect. These experiments varied in both the methods used for accelerating thought (i.e., instructions to brainstorm freely, exposure to multiple ideas, encouragement to plagiarize others' ideas, performance of easy cognitive tasks, narration of a silent video in fast-forward, and experimentally controlled reading speed) and the contents of the thoughts that were induced (from thoughts about money-making schemes to thoughts of five-letter words). The results suggested that effects of thought speed on mood are partially rooted in the subjective experience of thought speed. The results also suggested that these effects can be attributed to the joy-enhancing effects of fast thinking (rather than only to the joy-killing effects of slow thinking). This work is inspired by observations of a link between "racing thoughts" and euphoria in cases of clinical mania, and potential implications of that observed link are discussed.

  8. Reflections on the renewed significance of Huguenot thought

    Directory of Open Access Journals (Sweden)

    Marie P. Charles

    1983-03-01

    Full Text Available Traditional Huguenot values might be usefully employed in the planning of political objectives for the future. In rejecting the views which have rendered wan a mere object, a new form of spiritual humanism is advocated. In contrast to the merely “structural'' and the “communicative” a form of philosophy which allows for an essentialist participation should be encouraged. The present situation in South Africa, within the framework o f post-colonial Africa, is discussed, and certain parallels drawn between the Afrikaners and the bourgeoisie in France following the Revolution of 1789. It is pointed out that the Afrikaner “bourgeois” people can be regarded as being perhaps the only remaining bourgeois people still in a progressive period o f their civilization. This makes them a powerful force. The question now to be considered is to what extent the labouring classes could be drawn into the mainstream - and it is not impossible that this could be achieved without upheaval if old Huguenot values were to be respected. Certain writers like Ellul, Brun, and Aron suggest creatively ways in which, in contrast to the Saussurean principle of the arbitrariness of the linguistic sign, forms of unity may be attained. The arbitrariness of the linguistic sign and its consequences should be avoided at all levels. It is therefore suggested that the original Huguenot values could help contemporary scholars and politicians lo plan ahead in a deductive rather than an inductive n a y for a more just and credible future. What has to be sought, as had been the ease with Calvin too, is the deduction of Cod rather than the inductions of man.

    This study sought to replicate and extend investigations of current models of sexual dysfunction (Barlow, 2002; Janssen, Everaerd, Spiering, & Janssen, 2000) which implicate factors such as spectatoring, failure to use ameliorative strategies, and information processing biases in the development and persistence of sexual difficulties. A sample of 165 (n = 71 men) undergraduates completed measures of sexual dysfunction and relationship satisfaction, and reported on the content and frequency of non-erotic thoughts during sex with a partner (i.e., spectatoring), the emotional impact of non-erotic thoughts, and the strategies used to manage them. They also reported on their main sexual functioning difficulties and the strategies they used to manage those difficulties. Finally, participants were presented with a series of hypothetical sexual scenarios and were asked to report their immediate interpretation of events in the scenario. The content of non-erotic thoughts was similar to previous work (Purdon & Holdaway, 2006), although gender differences in thought content were less pronounced. As in previous research, greater frequency of, and anxiety evoked by, non-erotic thoughts was associated with poorer sexual functioning, but we found that this was over and above relationship satisfaction. Participants both high and low in sexual functioning reported using a variety of strategies to manage their non-erotic thoughts, thought suppression being the least effective, and also used a variety of strategies to manage sexual difficulties. Poorer sexual functioning was associated with more negative interpretations of ambiguous sexual scenarios, but this was mediated by relationship satisfaction. However, positive interpretations were predicted by sexual functioning. Results were discussed in terms of their theoretical and clinical implications.

  11. Some thoughts about risk

    International Nuclear Information System (INIS)

    Jennekens, J.H.

    1986-05-01

    The author discusses how the concept of risk is perceived differently by the scientist and the man in the street, and mentions the problems that this can sometimes pose for the regulator. He also gives examples of inconsistencies and contradictions in various areas of risk management. He concludes by noting that so-called accidents usually do not occur by chance, but that system or component failures are always due to some form of human error. The objective of risk management is to ensure, by a process of rigorous analysis, that both the probability and consequences of such failures are minimized

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

    Full Text Available The rehabilitation process is a continuum of actions, changes obtained on its individual stages are the key to the success of the next step, a prisoner’s commitment in the process of changing is a very important part of rehabilitation. The prisoners may choose whether they actively participate in the rehabilitation process or not. If they decide, the completed tasks are evaluated by the staff. Currently it is still being looked for effective work with prisoners, how to change their behavior and the way of thinking. The stuff should build a specific interpersonal relationships with the prisoners because it creates opportunities to motivate the prisoners and let them see their strong points.

    2015-01-01

    In 1983, a group of 14 prominent psychotherapy process researchers attended a workshop sponsored by the US National Institute of Mental Health. Although the previous decade had seen a marked emphasis on psychotherapy outcome research, there had also been several major advances in the field of process research. The goals of the workshop were to review the current state of the field, address methodological and conceptual issues, and provide recommendations to advance scholarship in this area. In this paper, we summarize the major themes of the workshop and consider the degree to which its recommendations have come to fruition via subsequent developments in the field. Although 30 years have passed since the workshop was held, its insights remain highly relevant to psychotherapy process research today.

    Slowed information processing speed is commonly reported in persons with multiple sclerosis (MS), and is typically investigated using clinical neuropsychological tests, which provide sensitive indices of mean-level information processing speed. However, recent studies have demonstrated that within-person variability or intra-individual variability (IIV) in information processing speed may be a more sensitive indicator of neurologic status than mean-level performance on clinical tests. We evaluated the neural basis of increased IIV in mildly affected relapsing-remitting MS patients by characterizing the relation between IIV (controlling for mean-level performance) and white matter integrity using diffusion tensor imaging (DTI). Twenty women with relapsing-remitting MS and 20 matched control participants completed the Computerized Test of Information Processing (CTIP), from which both mean response time and IIV were calculated. Other clinical measures of information processing speed were also collected. Relations between IIV on the CTIP and DTI metrics of white matter microstructure were evaluated using tract-based spatial statistics. We observed slower and more variable responses on the CTIP in MS patients relative to controls. Significant relations between white matter microstructure and IIV were observed for MS patients. Increased IIV was associated with reduced integrity in more white matter tracts than was slowed information processing speed as measured by either mean CTIP response time or other neuropsychological test scores. Thus, despite the common use of mean-level performance as an index of cognitive dysfunction in MS, IIV may be more sensitive to the overall burden of white matter disease at the microstructural level. Furthermore, our study highlights the potential value of considering within-person fluctuations, in addition to mean-level performance, for uncovering brain-behavior relationships in neurologic disorders with widespread white matter pathology.

    Full Text Available Recognizing the importance of nutrition as part of the grand challenges faced by humanity—the current epidemic of non-communicable diseases (NCDs, sustainability and maintenance of Planetary Health—the United Nations (UN has declared 2016–2025 the Decade of Nutrition. Research continues to underscore the extent to which ultra-processed foods dominate the contemporary nutritional landscape. Moreover, the dual role played by food technology and marketing in the expansion of ultra-processed foods is under increased scrutiny. As public health experts and clinicians contend with a crisis of NCDs, attempting to untangle a knotted assortment of interrelated strands of causation, an examination of the early origins of highly-marketed ultra-processed foods can provide valuable lessons. Here, we illuminate a little-known piece of history in the annals of ultra-processed nutritional science and childhood welfare. Astrofood was a commercially-marketed, collaborative government-industry effort that brought soy protein-enriched Twinkies as a nutritive breakfast cake to disadvantaged children; its concept and delivery demonstrated an unwillingness to deal with root-cause challenges. Although its official tenure was only about 7 years, we argue that Astrofood and its total food engineering still resonate throughout the global ultra-processed nutritional landscape. New scientific advances in nutritional psychiatry and the microbiome are on a collision course with the profits, marketing and intellectual dishonesty of the ultra-processed food industry. Solutions to the grand challenges of the Decade of Nutrition may be found in lessons from Astrofood. They provide clues to undoing the tangled knots which otherwise maintain an untenable status quo.

    2005-01-01

    As business processes and information transactions have become an inextricably intertwined with the Web, the importance of assignment, registration, discovery, and maintenance of identifiers has increased. In spite of this, integrated frameworks for managing identifiers have been slow to emerge. Instead, identification systems arise (quite naturally) from immediate business needs without consideration for how they fit into larger information architectures. In addition, many legacy identifier systems further complicate the landscape, making it difficult for content managers to select and deploy identifier systems that meet both the business case and long term information management objectives. This presentation will outline a model for evaluating identifier applications and the functional requirements of the systems necessary to support them. The model is based on a layered analysis of the characteristics of identifier systems, including: * Functional characteristics * Technology * Policy * Business * Social T...

    Full Text Available This study was conducted to investigate the data about the Bologna Process on the websites of universities’ undergraduate nursing programs in Turkey. In this descriptive study, all state and private universities which have BSc Nursing Programs and are within the scope of the Council of Higher Education of Turkey were included. Data were collected between May 1st and June 1st, 2015 by searching the websites of universities that were included in this study. An Evaluation Form that was developed by the researchers was used to collect data. Data were analyzed by using frequencies and percentages. We found that 77.2% of the universities included in the study were state universities and information about the Bologna Process could be found by using the website link on the main page in 65.3% of these universities. The majority of the universities (87.1% had general information about their program but 44% did not take the European Credit Transfer System into consideration on compulsory lessons and 41% of them on elective lessons. It was found that the majority of essential nursing lessons held by eight departments in BSc of Nursing programs had an Information Package of Lessons (68.1%-77.6% and that this package contained information on the European Credit Transfer System Credits in 72.3%-82.7% and calculations of student workload in 54.2%-65.6%. In conclusion, the universities with BSc Nursing Program did not have full information about the Bologna Process on their websites. We recommend making the necessary updates on these websites according to the standard format of the Council of Higher Education of Turkey to avoid giving inadequate and false information about the Bologna Process.

  12. Low-Frequency Cortical Entrainment to Speech Reflects Phoneme-Level Processing.

    Science.gov (United States)

    Di Liberto, Giovanni M; O'Sullivan, James A; Lalor, Edmund C

    2015-10-05

    The human ability to understand speech is underpinned by a hierarchical auditory system whose successive stages process increasingly complex attributes of the acoustic input. It has been suggested that to produce categorical speech perception, this system must elicit consistent neural responses to speech tokens (e.g., phonemes) despite variations in their acoustics. Here, using electroencephalography (EEG), we provide evidence for this categorical phoneme-level speech processing by showing that the relationship between continuous speech and neural activity is best described when that speech is represented using both low-level spectrotemporal information and categorical labeling of phonetic features. Furthermore, the mapping between phonemes and EEG becomes more discriminative for phonetic features at longer latencies, in line with what one might expect from a hierarchical system. Importantly, these effects are not seen for time-reversed speech. These findings may form the basis for future research on natural language processing in specific cohorts of interest and for broader insights into how brains transform acoustic input into meaning.

    2013-02-01

    Fluidized bed granulation is a commonly used unit operation in the pharmaceutical industry. But still to obtain and control the desired granule size is challenging due to many process variables affecting the final product. Focused beam reflectance measurement (FBRM, Mettler-Toledo, Switzerland) is an increasingly popular particle growth analysis technique. FBRM tool was installed in two different locations inside a fluidized bed granulator (GPCG2, Glatt, Binzen) in order to monitor the granulation growth kinetics. An experimental design was created to study the effect of process variables using FBRM probe and comparing the results with the one's measured by sieve analysis. The probe location is of major importance to get smooth and robust curves. The excess feeding of binder solution might lead to agglomeration and thus to process collapse, however this phenomenon was clearly detected with FBRM method. On the other hand, the process variables at certain levels might affect the FBRM efficiency by blocking the probe window with sticky particles. A good correlation was obtained (R(2) = 0.95) between FBRM and sieve analysis mean particle size. The proposed in-line monitoring tool enables the operator to select appropriate process parameters and control the wet granulation process more efficiently.

The social work class seeks new foundations that allow within the context of structural change, the strengthening of professional identity and challenge of the vestiges of intellectual segregation that historical constraints have left. This paper seeks to outline a research strategy for reconciliation and coordination of intellectual and professional work in order to give visibility to new and different domains of interpretation and action, while claiming that considering pluri-perspectives potentiates the knowledge transformation process. Underlining this confluence of complex thinking elements, this article incorporates the space-time dimension and discusses and recognizes the unavoidable circularity as a way to interrogate knowledge that is compartmentalized and fragmented, placing an emphasis both on knowledge and on the interrelationship between knowing, doing, being and relating. In addition, examines the recognition of the nature of those relationships among various disciplines and perspectives.

    Full text: Infrared reflection absorption spectroscopy (IRRAS) was applied to study the regularities of radiation conversion of hexane on the surface of aluminum. The research object was the thin polished aluminum plate by mark of AD-00 with reflection coefficient R=0.8†0.85 in infrared range λ=2.2†15 μ . As adsorbate unsaturated vapors of spectroscopy clear hexane were used. The absorption of hexane (C 2 H 14 ) was being studied manometric at pressures P=(0.1†1.0)·10 2 Pa , what corresponded to monolayer value of 1-10. The samples were irradiated with γ-quanta of 60 Co with D=1.03 Gy·s -1 doze rate. Infrared reflection spectrum when linear-polarized radiation fall on the sample under angle ψ=10 o was measured by spectrophotometer 'Specord 71 JR' in diapason of 4000-650cm -1 at the temperature by mean of special reflecting arrangements. Formation of molecular hydrogen (H 2 ) and other gaseous products of decomposition were controlled by chromotographical and infrared spectroscopical methods. The analysis of hexane infrared absorption spectra after radiation-stimulated adsorption on the surface of aluminum, points out the formation of H-bonded hydrocarbon complex ( ν∼2680cm -1 ) with much loosening of C-H bond (the molecular form of absorption) and the possibility of proceeding dissociative absorption with formation of metal-alkyls (ν∼2880, 2920, 2970 cm -1 ). Probability of the last mentioned process, which proceeds in the most defective centers, increases with increasing of γ-radiation doze. It was established that the radiation processes in hetero system Al-ads.C 6 H 14 accelerate the radiolysis of hexane. At all these the radiation decomposition of hexane in hetero system Al-ads.C 6 H 14 is accompanied by formation the surface hydrides (ν∼1700-2000 cm -1 ), acetylene (ν∼3200-3300 cm -1 ), ethylene (ν∼980 cm -1 ), and also gaseous products of molecular hydrogen decomposition (H 2 ) and hydrocarbons C 1 -C 5 (bands with maxima 770, 790

  1. The Formation of Chimeric Nanomorphologies, as a Reflection of Naturally Occurring Thermodynamic Processes

    Science.gov (United States)

    Naziris, N.; Demetzos, C.

    2017-11-01

    The self-assembly process of different in nature biomaterials leads to the morphogenesis of various nano-structures, where the individual molecule properties (e.g. hydrophilic-to-hydrophobic balance and elasticity), profoundly affect the intermediate surfaces’ interfacial thermodynamics. Herein, the mixing of a phospholipid and an amphiphilic block copolymer, through the thin-film hydration method, gave different morphologies, among which there were vesicles (i.e. liposomes and polymersomes), micelles and worm-like structures. The formation of such variety of structures is attributed to divergent entropic pathways, which are determined by a number of parameters, such as the lipid:polymer molar ratio and the polymer composition. The developed nanosystems are considered as chimeric/mixed, because of the two different in type biomaterials that compose them. The vesicles also exhibited membrane “irregularities”, which are connected with their biophysical behavior. Nature has “chosen” vesicular forms to be the thermodynamically stable “biological apartments”, in which life was enclosed and additionally, vesicles provided compartmentalized systems, where the intracellular environment was built. Phospholipid properties result in membranes/bilayers that harmonically assimilate other molecules, like proteins and retain their integrity and functionality, while gaining additional features. A cause that alters this relationship might induce changes in the membrane composition and morphology, with respect to lipid rafts/domains, what has been linked with the activation and development of certain human disorders/diseases. The self-assembly of two different biomaterials into various structures that present distinct membrane phenomena is believed to simulate these natural processes.

    Plasma oxytocin (OT) and arginine vasopressin (AVP) are associated with individual differences in emotional responses and behaviors. The amygdala is considered to be an important brain region for regulating emotion-based behavior, with OT and AVP modulating activity in the amygdala during the processing of negative emotions. In particular, increased OT levels may diminish amygdala activation (anxiolytic effects) and enhanced AVP levels may augment amygdala activation (anxiogenic effects) when negative emotions are processed. A growing body of research has shown that the effects of OT and AVP are modulated by sex: the aforementioned anxiolytic effects of OT and the anxiogenic effects of AVP occur in men, but not in women. However, we have little knowledge regarding the biological mechanisms underlying OT and AVP plasma levels or their respective anxiogenic and anxiolytic effects; similarly, little is known about the causes and nature of sex differences related to these neuropeptides and their effects on emotional processing. In the current study, we focused on the neural functions associated with the biological mechanisms underlying such effects. We hypothesized that amygdala activation would correlate with trait plasma OT (anxiolytic effects) and AVP (anxiogenic effects) levels because the amygdala is thought to affect the coordinated release of these neuropeptides following affective experiences. We further hypothesized that the effects would be modulated by sex. We assessed 51 participants (male and female) using a paradigm involving negative emotion in conjunction with functional magnetic resonance imaging and measurements of plasma OT and AVP levels. We determined that increased plasma AVP levels were positively associated with amygdala activation (anxiogenic effects) in men, but not in women. These findings highlight the potential underlying neural mechanisms of plasma AVP levels in men.

    Results: Ten percent (13/128 of students had the intuitive answers to the three questions (suggesting they generally relied on System 1 thinking while almost half (44% answered all three correctly (indicating full analytical, System 2 thinking. Only 3-13% had incorrect answers (i.e. that were neither the analytical nor the intuitive responses. Non-native English speaking students (n = 11 had a lower mean number of correct answers compared to native English speakers (n = 117: 1.0 s 2.12 respectfully: p < 0.01. As students progressed through questions 1 to 3, the percentage of correct System 2 answers increased and the percentage of intuitive answers decreased in both the pre-clinical and clinical students. Conclusions: Up to half of the medical students demonstrated full or partial reliance on System 1 (intuitive thinking in response to these analytical questions. While their CRT performance has no claims to make as to their future expertise as clinicians, the test may be used in helping students to understand the importance of awareness and regulation of their thinking processes in clinical practice.

    Biochemical and structural leaf properties such as chlorophyll content (Chl), nitrogen content (N), leaf water content (LWC), and specific leaf area (SLA) have the benefit to be estimated through nondestructive spectral measurements. Current practices, however, mainly focus on a limited amount of wavelength bands while more information could be extracted from other wavelengths in the full range (400-2500nm) spectrum. In this research, leaf characteristics were estimated from a field-based multi-species dataset, covering a wide range in leaf structures and Chl concentrations. The dataset contains leaves with extremely high Chl concentrations (>100μgcm(-2)), which are seldom estimated. Parameter retrieval was conducted with the machine learning regression algorithm Gaussian Processes (GP), which is able to perform adaptive, nonlinear data fitting for complex datasets. Moreover, insight in relevant bands is provided during the development of a regression model. Consequently, the physical meaning of the model can be explored. Best estimates of SLA, LWC and Chl yielded a best obtained normalized root mean square error of 6.0%, 7.7%, 9.1%, respectively. Several distinct wavebands were chosen across the whole spectrum. A band in the red edge (710nm) appeared to be most important for the estimation of Chl. Interestingly, spectral features related to biochemicals with a structural or carbon storage function (e.g. 1090, 1550, 1670, 1730nm) were found important not only for estimation of SLA, but also for LWC, Chl or N estimation. Similar, Chl estimation was also helped by some wavebands related to water content (950, 1430nm) due to correlation between the parameters. It is shown that leaf parameter retrieval by GP regression is successful, and able to cope with large structural differences between leaves. Copyright © 2014 Elsevier B.V. All rights reserved.

  8. The N400 and Late Positive Complex (LPC Effects Reflect Controlled Rather than Automatic Mechanisms of Sentence Processing

    Full Text Available This study compared automatic and controlled cognitive processes that underlie event-related potentials (ERPs effects during speech perception. Sentences were presented to French native speakers, and the final word could be congruent or incongruent, and presented at one of four levels of degradation (using a modulation with pink noise: no degradation, mild degradation (2 levels, or strong degradation. We assumed that degradation impairs controlled more than automatic processes. The N400 and Late Positive Complex (LPC effects were defined as the differences between the corresponding wave amplitudes to incongruent words minus congruent words. Under mild degradation, where controlled sentence-level processing could still occur (as indicated by behavioral data, both N400 and LPC effects were delayed and the latter effect was reduced. Under strong degradation, where sentence processing was rather automatic (as indicated by behavioral data, no ERP effect remained. These results suggest that ERP effects elicited in complex contexts, such as sentences, reflect controlled rather than automatic mechanisms of speech processing. These results differ from the results of experiments that used word-pair or word-list paradigms.

    Human information processing is sensitive to aversive stimuli, in particular to negative cues that indicate a threat to physical integrity. We investigated the extent to which these findings can be transferred to stimuli that are associated with a social rather than a physical threat. Event-related potentials were recorded during silent reading of neutral, positive, physically threatening, and socially threatening words, whereby socially threatening words were represented by swear words. We found facilitated processing of positive and physically threatening words in contrast to both neutral and socially threatening words at a first potential that emerged at about 120 ms after stimulus onset. At a semantic processing stage reflected by the N400, processing of all classes of affective words, including socially threatening words, differed from neutral words. We conclude that socially threatening words as well as neutral words capture more attentional resources than positive and physically threatening words at early stages. However, social threatening words are processed in a manner similar to other emotional words and different from neutral words at higher levels.

  10. Propositions toward the development of a psychological theory of thought

    Full Text Available Thought is considered a psychological concept associated with an individual’s mental ex- istence. It is apparent that a great deal of research has been focused on thought as an area of study. however, there is no psychological theory of thought which provides an expla- nation for its nature and structural organization. So far, researchers have mainly looked at the ways this concept is expressed, rather than investigating what it actually is. In this study, however, based on studies of the functions of the psyche, mental processes, and the neurophysiological bases of mental activity, thought is identified as a need-emotion- intentional substance existing in the human being’s inner world. In keeping with this understanding of thought, the hypothesis that thought generation is caused by desire and experience (feeling and emotion is put forward. An individual’s thought is linked to his behavior or motivation for activity, and is followed by an emotional experience. The process of thought generation is regarded through the mechanism of behavioral motiva- tion. The primary purpose of this mechanism is to define the qualities of the external objects that serve for need satisfaction and functionality in individuals. The ability to generate thoughts is a feature of thinking related to an individual’s mental ability or frame of mind. From this standpoint, a person’s mentality is considered to be the capacity of the individual to generate thoughts and work through thoughts. It is shown that the abil- ity to generate thoughts and establish relationships within a stream of consciousness is characteristic of human intelligence. Some basic propositions toward a development of a psychological theory of thought are introduced.

  12. 024 PP: MEANINGFUL AND ENGAGING, OR TOKENISTIC? REFLECTIONS ON COLLABORATIVE ENGAGEMENT IN THE PROCESS OF DESIGNING SEXUAL HEALTH INTERVENTIONS

    Science.gov (United States)

    Boydell, N; McDaid, L

    2017-01-01

    Working with non-academic partners and including participants, and other stakeholders, in the design and delivery of research is emerging as a critical element in the field of health research. As researchers based in an interdisciplinary team with a focus on the development of sexual health interventions, we have long recognised that engagement with individuals and communities is a critical part of the research process, and actively sought out opportunities to collaborate with non-academic partners with a view to ensuring that our work is relevant in the ‘real-world’. While the increasing call for ‘collaboration’, ‘patient and public involvement’ and ‘co-production’ is welcome, we recognise the possibility that without critical reflection on the part of the research team, such engagement can lack meaning for those being asked to participate, potentially reducing its value and risking it being perceived as tokenistic. In this paper we reflect on our experiences as qualitative researchers for whom a key role in interdisciplinary research teams has been undertaking a number of ‘patient public involvement’ projects with both young people and gay, bisexual and other men who have sex with men (MSM) to inform the development of sexual health interventions. We critically reflect on some of the challenges and opportunities involved in this form of ‘consultation’, and explore the ethical implications of engaging stakeholders in identifying issues they consider important as part of the design and delivery of future interventions, but which may not be considered either a priority or feasible.

  14. Access is mainly a second-order process: SDT models whether phenomenally (first-order) conscious states are accessed by reflectively (second-order) conscious processes.

    Access can either be first-order or second-order. First order access concerns whether contents achieve representation in phenomenal consciousness at all; second-order access concerns whether phenomenally conscious contents are selected for metacognitive, higher order processing by reflective consciousness. When the optional and flexible nature of second-order access is kept in mind, there remain strong reasons to believe that exclusion failure can indeed isolate phenomenally conscious stimuli that are not so accessed. Irvine's [Irvine, E. (2009). Signal detection theory, the exclusion failure paradigm and weak consciousness-Evidence for the access/phenomenal distinction? Consciousness and Cognition.] partial access argument fails because exclusion failure is indeed due to lack of second-order access, not insufficient phenomenally conscious information. Further, the enable account conforms with both qualitative differences and subjective report, and is simpler than the endow account. Finally, although first-order access may be a distinct and important process, second-order access arguably reflects the core meaning of access generally.

  15. Impulsivity, impulsive and reflective processes and the development of alcohol use and misuse in adolescents and young adults

    Full Text Available This paper contrasts dual-process and personality approaches in the prediction of addictive behaviors and related risk behaviors. In dual-process models, behavior is described as the joint outcome of qualitatively different “impulsive” (or associative and “reflective” processes. There are important individual differences regarding both types of processes, and the relative strength of both in a specific situation is influenced by prior behavior and state variables (e.g., fatigue, alcohol use. From this perspective, a specific behavior (e.g., alcohol misuse can be predicted by the combined indices of the behavior-related impulsive processes (e.g., associations with alcohol, and reflective processes, including the ability to refrain from a motivationally salient action. Personality approaches have reported that general traits such as impulsivity predict addictive behaviors. Here we contrast these two approaches, with supplementary analyses on four datasets. We hypothesized that trait impulsivity can predict specific risky behaviors, but that its predictive power disappears once specific behavior-related associations, indicators of executive functioning, and their interaction are entered into the equation. In all four studies the observed interaction between specific associations and Executive Control (EC was robust: trait impulsivity did not diminish the prediction of alcohol use by the interaction. Trait impulsivity was not always related to alcohol use, and when it was, the predictive power disappeared after entering the interaction between behavior-specific associations and EC in one study, but not in the other. These findings are interpreted in relation to the validity of the measurements used, which leads to a more refined hypothesis.

  16. What can other animals tell us about human social cognition?An evolutionary perspective on reflective and reflexive processing

    Directory of Open Access Journals (Sweden)

    Erin E Hecht

    2012-07-01

    Full Text Available Human neuroscience has seen a recent boom in studies on reflective, controlled, explicit social cognitive functions like imitation, perspective‐taking, and empathy. The relationship of these higher‐level functions to lower‐level, reflexive, automatic, implicit functions is an area of current research. As the field continues to address this relationship, we suggest that an evolutionary, comparative approach will be useful, even essential. There is a large body of research on reflexive, automatic, implicit processes in animals. A growing perspective sees social cognitive processes as phylogenically continuous, making findings in other species relevant for understanding our own. One of these phylogenically continuous processes appears to be self‐other matching or simulation. Mice are more sensitive to pain after watching other mice experience pain; geese experience heart rate increases when seeing their mate in conflict; and infant macaques, chimpanzees, and humans automatically mimic adult facial expressions. In this article, we review findings in different species that illustrate how such reflexive processes are related to (higher order reflexive processes, such as cognitive empathy, theory of mind, and learning by imitation. We do so in the context of self‐other matching in three different domains – in the motor domain (somatomotor movements, in the perceptual domain (eye movements and cognition about visual perception, and in the autonomic/emotional domain. We also review research on the developmental origin of these processes and their neural bases across species. We highlight gaps in existing knowledge and point out some questions for future research. We conclude that our understanding of the psychological and neural mechanisms of self‐other mapping and other functions in our own species can be informed by considering the layered complexity these functions in other species.

    Innovative educational strategies can provide variety and enhance student learning while addressing complex logistical and financial issues facing modern anatomy education. Observe-Reflect-Draw-Edit-Repeat (ORDER), a novel cyclical artistic process, has been designed based on cognitivist and constructivist learning theories, and on processes of critical observation, reflection and drawing in anatomy learning. ORDER was initially investigated in the context of a compulsory first year surface anatomy practical (ORDER-SAP) at a United Kingdom medical school in which a cross-over trial with pre-post anatomy knowledge testing was utilized and student perceptions were identified. Despite positive perceptions of ORDER-SAP, medical student (n = 154) pre-post knowledge test scores were significantly greater (P learning methods (3.26, SD = ±2.25) than with ORDER-SAP (2.17, ±2.30). Based on these findings, ORDER was modified and evaluated in the context of an optional self-directed gross anatomy online interactive tutorial (ORDER-IT) for participating first year medical students (n = 55). Student performance was significantly greater (P  0.05) to those students without these characteristics. These findings will be of value to anatomy instructors seeking to engage students from diverse learning backgrounds in a research-led, innovative, time and cost-effective learning method, in the context of contrasting learning environments.

    The value of collaborative concept mapping in assisting students to develop an understanding of complex concepts across a broad range of basic and applied science subjects is well documented. Less is known about students' learning processes that occur during the construction of a concept map, especially in the context of clinical cases in veterinary medicine. This study investigated the unfolding collaborative learning processes that took place in real-time concept mapping of a clinical case by veterinary medical students and explored students' and their teacher's reflections on the value of this activity. This study had two parts. The first part investigated the cognitive and metacognitive learning processes of two groups of students who displayed divergent learning outcomes in a concept mapping task. Meaningful group differences were found in their level of learning engagement in terms of the extent to which they spent time understanding and co-constructing knowledge along with completing the task at hand. The second part explored students' and their teacher's views on the value of concept mapping as a learning and teaching tool. The students' and their teacher's perceptions revealed congruent and contrasting notions about the usefulness of concept mapping. The relevance of concept mapping to clinical case-based learning in veterinary medicine is discussed, along with directions for future research.

    As part of a cooperative effort among the U.S. Geological Survey (USGS), the U.S. Department of Energy, and the U.S. Department of the Interior Bureau of Ocean Energy Management, two grids of two-dimensional multichannel seismic reflection data were acquired in the Gulf of Mexico over lease blocks Green Canyon 955 and Walker Ridge 313 between April 18 and May 3, 2013. The purpose of the data acquisition was to fill knowledge gaps in an ongoing study of known gas hydrate accumulations in the area. These data were initially processed onboard the recording ship R/V Pelican for more quality control during the recording. The data were subsequently processed in detail by the U.S. Geological Survey in Denver, Colorado, in two phases. The first phase was to create a “kinematic” dataset that removed extensive noise present in the data but did not preserve relative amplitudes. The second phase was to create a true relative amplitude dataset that included noise removal and “wavelet” deconvolution that preserved the amplitude information. This report describes the processing techniques used to create both datasets.

    2017-10-01

    Full Text Available Studying the problems related to the process of the Azerbaijanian people formation requires a comprehensive analysis of mutual relations of the Turkic tribes – the Huns, the Sabirs and the Khazars – with the local population of Azerbaijan in the early Middle Ages. The article is devoted to the process of penetration of the Huns, the Sabirs and the Khazars to Azerbaijan, their role in the formation of the Azerbaijanian people and the reflection of this process in the country’s toponymy. In the early Middle Ages the process of penetration of Turkic tribes in Azerbaijan from the north, through the Derbent passage, intensified. Primary sources indicate that over the centuries the Huns (3rd – 4th centuries, the Sabirs (5th – 6th centuries and the Khazars (7th – 8th centuries made continuous attacks on Azerbaijan and neighboring countries from the north. Upon the arrival of the Turkic tribes in Azerbaijan from the north in the 3rd – 4th centuries, the Turkic language in the country was extensively spread. Just since then the ethnotoponyms “Hun”, “Suvar” and “Khazar” became consolidated in the toponymy of Azerbaijan. Revealing the meaning of toponyms, ethnonyms, town names, hydronyms, introduced in language use in the 3rd – 8th centuries and associated with the aforementioned tribes, has exceptional value for recreating the ethnic view of Azerbaijan of the studied epoch. They let us come to the conclusion that the Huns, the Sabirs and the Khazars were important ethnic elements in the process of ethnogenesis of the Azerbaijanian people.

    Introduction: It is generally accepted that metabolic inflammation in the liver is an important driver of disease progression in NASH and associated matrix remodeling/fibrosis. However, the exact molecular inflammatory mechanisms are poorly defined in human studies. Investigation of key pathogenic mechanisms requires the use of pre-clinical models, for instance for time-resolved studies. Such models must reflect molecular disease processes of importance in patients. Herein we characterized inflammation in NASH patients on the molecular level by transcriptomics and investigated whether key human disease pathways can be recapitulated experimentally in Ldlr -/- .Leiden mice, an established pre-clinical model of NASH. Methods: Human molecular inflammatory processes were defined using a publicly available NASH gene expression profiling dataset (GSE48452) allowing the comparison of biopsy-confirmed NASH patients with normal controls. Gene profiling data from high-fat diet (HFD)-fed Ldlr -/- .Leiden mice (GSE109345) were used for assessment of the translational value of these mice. Results: In human NASH livers, we observed regulation of 65 canonical pathways of which the majority was involved in inflammation (32%), lipid metabolism (16%), and extracellular matrix/remodeling (12%). A similar distribution of pathways across these categories, inflammation (36%), lipid metabolism (24%) and extracellular matrix/remodeling (8%) was observed in HFD-fed Ldlr -/- .Leiden mice. Detailed evaluation of these pathways revealed that a substantial proportion (11 out of 13) of human NASH inflammatory pathways was recapitulated in Ldlr -/- .Leiden mice. Furthermore, the activation state of identified master regulators of inflammation (i.e., specific transcription factors, cytokines, and growth factors) in human NASH was largely reflected in Ldlr -/- .Leiden mice, further substantiating its translational value. Conclusion: Human NASH is characterized by upregulation of specific

    Full Text Available Many curriculums assume that the new generation of students are digital natives and information literate. However, studies show that this is not often the case. From these studies and our own experiences working with multidisciplinary students in the Health Sciences we found that students were not as information literate as required in the curriculum. Using Design Based Research as a method (following the four phases below, we developed a new information search process and a web-based tool with feedback opportunities from teachers and librarians in order to qualify the students competencies. Problem identification: Despite earlier initiatives from library and department, the students didn’t achieve higher levels of information literacy. Prototyping: Requirements and educational material were merged and tested while gathering feedback. Iterations: The prototype and feedback were evaluated and developed into a new information search process, which was tested and evaluated. Reflection and generalization: Initiative was taken to develope a web-based application visualizing the steps with the learning points: self-feedback, peer-feedback and counselor feedback. The result of the project is a new information search process model and a web-based learning environment called B!NKO 2.0. The evaluations have shown positive feedback on both the process and the web tool. The project has opened up new possibilities that go beyond the Health multidisciplinary students. A new project concerning the Humanities and Social Sciences is incipient. In this project new functionalities are also expected. B!NKO 2.0 has to a great extent shown its worth to help Health multidisciplinary students to get a deeper understanding of information literacy, and how to develop and change searches to get better results. B!NKO 2.0 has also given a positive "side effect” on the librarians work. Time spend on the "Book a Librarian” service have decreased for the librarians using

    In this article we present preliminary findings from a research program designed to investigate the value of alliance-focused training (AFT), a supervision approach designed to enhance therapists' ability to work constructively with negative therapeutic process. In the context of a multiple baseline design, all therapists began treating their patients using cognitive therapy and then joined AFT supervision groups at either session 8 or 16 of a 30 session protocol. Study I investigated the impact of AFT on patient and therapist interpersonal process as assessed through the Structural Analysis of Social Behavior (SASB). Study 2 investigated the impact of AFT on therapists' tendency to reflect on their relationships with their patients in an experientially grounded fashion, as assessed via the Experiencing Scale (EXP). Since one of the goals of AFT is to train therapists to use their own emerging feelings as important clues regarding what may be taking place in the therapeutic relationship, we hypothesized that they would show increased levels of EXP after undergoing AFT. The results of both studies 1 and 2 were for the most part consistent with hypotheses. Implications and future research directions are discussed.

    In creating the value-added product in not distant future, it is necessary and inevitable to establish a holistic and though-evoking approach to the engineering problem, which should be at least associated with the inter-disciplinary knowledge and thought processes across the whole engineering spheres. It is furthermore desirable to integrate it with trans-disciplinary aspects ranging from manufacturing culture, through liberal-arts engineering, and industrial sociology.   The thought-evoking approach can be exemplified and typified by representative engineering problems: unveiling essential features in ‘Tangential Force Ratio and Interface Pressure’, prototype development for ‘Bio-mimetic Needle’ and application of ‘Water-jet Machining to Artificial Hip Joint’, product innovation in ‘Heat Sink for Computer’, application of ‘Graph Theory’ to similarity evaluation of production systems, leverage among reciprocity attributes in ‘Industrial and Engineering Designs for Machine Enclosure’,...

    Peptide profiles of different drinking milk samples were examined to study how the peptide fingerprint of milk reflects processing conditions. The combination of a simple and fast method for peptide extraction using stage tips and MALDI-TOF-MS enabled the fast and easy generation and relative quantification of peptide fingerprints for high-temperature short-time (HTST), extended shelf life (ESL) and ultra-high temperature (UHT) milk of the same dairies. The relative quantity of 16 peptides changed as a function of increasing heat load. Additional heating experiments showed that among those, the intensity of peptide β-casein 196-209 (m/z 1460.9Da) was most heavily influenced by heat treatment indicating a putative marker peptide for milk processing conditions. Storage experiments with HTST- and UHT milk revealed that the differences between different types of milk samples were not only caused by the heating process. Relevant was also the proteolytic activity of enzymes during storage, which were differently influenced by the heat treatment. These results indicate that the peptide profile may be suitable to monitor processing as well as storage conditions of milk. In the present study, peptide profiling of different types of milk was carried out by MALDI-TOF-MS after stage-tip extraction and relative quantification using an internal reference peptide. Although MALDI-TOF-MS covers only part of the peptidome, the method is easy and quick and is, therefore, suited for routine analysis to address several aspects of food authenticity. Using this method, 16 native peptides were detected in milk that could be modulated by different industrial processes. Subsequent heating and storage experiments with pasteurized and UHT milk confirmed that these peptides are indeed related to the production or storage conditions of the respective products. Furthermore, the heating experiments revealed one peptide, namely the β-casein-derived sequence β-casein 196-209, which underwent

  14. Positive Stress and Reflective Practice Among Entrepreneurs

    Full Text Available While heavy stress loads seem an unavoidable aspect of entrepreneurship, the positive side of stress (often referred to as ‘eustress’ remains a neglected area of research. This paper contributes to entrepreneurship research by linking the research streams of eustress and reflective practice. As a tool for analysing and developing thoughts and actions, reflective practice plays an important role in the interpretative work essential to positive stress experiences. Following an overview of approaches to stress at work, eustress and reflective practice, the paper explores how entrepreneurs experience the role of positive stress and reflective practice in their work and describes the reflective tools utilized by entrepreneurs in promoting eustress. The research process was designed to support reflective dialogue among the 21 Finnish entrepreneurs from different fields who participated in the study, with results based mainly on qualitative interviews. Nine of the interviewed entrepreneurs also kept a positive stress diary, including a three-day physiological measurement analysing their heartbeat variability. The findings suggest that positive stress and reflective practice are intertwined in the experiences of entrepreneurs and illustrate the role of reflective practice as a crucial toolset for promoting positive stress, comprising six reflective tools: studying oneself, changing one’s point of view, putting things into perspective, harnessing a feeling of trust, regulating resources and engaging in dialogue. Individual reflective capabilities vary, and a theory-driven division of reflective practice into individual, social and contextual dimensions is considered useful in understanding those differences. The research offers a starting point for exploring how eustress and reflective practice affect the well-being of entrepreneurs

    The mere thought effect is defined in part by the tendency of self-reflective thought to heighten the generation of and reflection on attitude-consistent thoughts. By focusing on individuals' fears of invalidity, we explored the possibility that the mere opportunity for thought sometimes motivates reflection on attitude-inconsistent thoughts. Across three experiments, dispositional and situational fear of invalidity was shown to heighten reflection on attitude-inconsistent thoughts. This heightened reflection, in turn, interacted with individuals' thought confidence to determine whether attitude-inconsistent thoughts were assimilated or refuted and consequently whether individuals' attitudes and behavioral intentions depolarized or polarized following a sufficient opportunity for thought, respectively. These findings emphasize the impact of motivational influences on thought reflection and generation, the importance of thought confidence in the assimilation and refutation of self-generated thought, and the dynamic means by which the mere thought bias can impact self-persuasion.

  16. The Transference of Gender-based Norms in the Law Reform Process: A Reflection on my Work in Thailand

    Full Text Available In 2008, I spent a year as a Rule of Law specialist in Thailand with the International Rescue Committee (IRC, as part of a fellowship program for human rights lawyers. I was assigned the task of facilitating the development of a comprehensive legal code for the refugee camps along the border between Thailand and /Burma. As part of my work, I also sought to increase gender-based protection under the law through the incorporation of Thai and international human rights norms. This paper is a reflection on the processes that occurred during my time at IRC. The reform project approached the transference of contentious international norms for protection of women and girls in two ways: a through the inclusive design of the law reform process and b the establishment of a prohibition on rules that clearly violated international or national law. By forming a representative drafting committee and placing an emphasis on community consultation as a precursor to code finalisation, refugee perspectives, particularly female perspectives, were given scope to inform interpretations of national and international legal standards. By requiring international and national legal compliance and placing an emphasis on explanation and clarification of international and national standards in discussions, the project supported downward transference of international norms to a specific community context. We hoped that, as a product of these two normative flows, the resulting legal code would be a sustainable mechanism for gender-based protection and redress in cases of sexual and gender-based violence. During negotiations, it became evident that the inclusive design of the law reform process had a more positive impact on the success of norms transference than the actual substance of the norm. The norms that were most readily accepted were those introduced by law reform committee members themselves. Local norm translators played a pivotal role in the norms diffusion process

    2016-11-01

    Full Text Available I show that there are good arguments and evidence to boot that support the language as an instrument of thought hypothesis. The underlying mechanisms of language, comprising of expressions structured hierarchically and recursively, provide a perspective (in the form of a conceptual structure on the world, for it is only via language that certain perspectives are available to us and to our thought processes. These mechanisms provide us with a uniquely human way of thinking and talking about the world that is different to the sort of thinking we share with other animals. If the primary function of language were communication then one would expect that the underlying mechanisms of language will be structured in a way that favours successful communication. I show that not only is this not the case, but that the underlying mechanisms of language are in fact structured in a way to maximise computational efficiency, even if it means causing communicative problems. Moreover, I discuss evidence from comparative, neuropathological, developmental, and neuroscientific evidence that supports the claim that language is an instrument of thought.

    Full Text Available The Campanian volcanism develops near the sea. Therefore, the geophysical study of the marine environment is a key to a better understanding of the tectonic evolution and the origin of volcanism in the area. An abundance of high quality seismic data in the marine sector, where little direct information is available, is critical to the study of Campanian volcanism. This paper concerns the reprocessing of a seismic reflection dataset acquired in Naples Bay and processed during 1973. Even though the overall data quality was high for that time, of course their acquisition technological limits have been overcome by the new processing. Our reprocessing aimed at: 1 reduction of random noise in the data; 2 removal of unwanted coherent events; 3 reduction of spatial aliasing by means of trace interpolation on Commod Shot Point (CSP gathering; 4 improvement of resolution of the seismic wavelet with spiking deconvolution algorithms and finally 5 reposition of reflectors in their correct locations in the space-TWT domain by means of dip moveout and post-stack time migration. A comparison between the new and old data shows that the new sections are characterized by a much higher S/N ratio. Diffraction hyperbole has been collapsed. Reverberations, ghosts and multiples have been removed or greatly attenuated, especially between the reflectors of interest, allowing us to follow them with more detail and with greater continuity. Furthermore, data resolution has been boosted by the reprocessing, allowing the interpreter to evaluate reflector position and continuity in greater detail. The reinterpretation phase of such lines, that is already in an advanced stage, will therefore allow us to gain new insights into the structural setting of the bay, with the aim of exploring the connection between tectonics and volcanism.

    Preparing practitioners for this rapidly changing and demanding health care environment is challenging. A surge in knowledge development and scientific advancement has placed a priority on technical skill and a focus on content driven educational processes that prepare students for evidence-based practice. However, the most difficult health care scenarios require thinking-in-action and thoughtfulness as well as didactic knowledge. It is our contention that interpretive educational methods, like narrative pedagogy, will promote judgment-based practice that includes use of evidence and delivery of thoughtful care. In this article, we describe and interpret a narrative approach to addictions content and teaching thoughtful practice. We present our pedagogical process, including observations and field notes, to show how interpretive pedagogies can be introduced into nursing curricula. By presenting this process, the reader is invited to consider interpretive methods as a way to inspire and habituate thoughtful practice and judgment-based care. Copyright 2009 Elsevier Ltd.

    Covering both the history of mathematics and of philosophy, Descartes's Mathematical Thought reconstructs the intellectual career of Descartes most comprehensively and originally in a global perspective including the history of early modern China and Japan. Especially, it shows what the concept of "mathesis universalis" meant before and during the period of Descartes and how it influenced the young Descartes. In fact, it was the most fundamental mathematical discipline during the seventeenth century, and for Descartes a key notion which may have led to his novel mathematics of algebraic analysis.

    Petty, Richard E; Briñol, Pablo; Tormala, Zakary L

    2002-05-01

    Previous research in the domain of attitude change has described 2 primary dimensions of thinking that impact persuasion processes and outcomes: the extent (amount) of thinking and the direction (valence) of issue-relevant thought. The authors examined the possibility that another, more meta-cognitive aspect of thinking is also important-the degree of confidence people have in their own thoughts. Four studies test the notion that thought confidence affects the extent of persuasion. When positive thoughts dominate in response to a message, increasing confidence in those thoughts increases persuasion, but when negative thoughts dominate, increasing confidence decreases persuasion. In addition, using self-reported and manipulated thought confidence in separate studies, the authors provide evidence that the magnitude of the attitude-thought relationship depends on the confidence people have in their thoughts. Finally, the authors also show that these self-validation effects are most likely in situations that foster high amounts of information processing activity.

  7. Hydrogen isotope analysis of amino acids and whole cells reflects biosynthetic processing of nutrient- and water-derived hydrogen

    2011-12-01

    Hydrogen (H) isotopes serve as sensitive tracers of biochemical processes that can be exploited to answer critical questions in biogeochemistry, ecology, and microbiology. Despite this apparent utility, relatively little is known about the specific mechanisms of H isotope fractionation involved in biosynthesis. In order to understand how organisms incorporate hydrogen from their chemical milieu into biomass, we have cultured the model bacterium E. coli MG1655 in a variety of media composed of deuterium-labeled nutrients and waters. Isotopic analysis of bulk cell mass reveals that the H fractionation between media water and cell material varies as a function of the nutrient source, with commonly used organic food sources (glucose and tryptone) leading to far smaller fractionation signals than non-standard ones (such as formamide, adenine, and urea). In addition, we have completed compound specific isotope analysis of amino acids using combined GC-IRMS. Amino acids harvested from E. coli cultured on glucose in water of varied D/H composition posses an extraordinary range of isotopic compositions (400-600 %). Furthermore, these amino acids follow a systematic distribution of D/H where proline is always heaviest and glycine is always lightest. However, when the short-chain peptide tryptone is used in place of glucose, only the non-essential amino acids reflect media water D/H values, suggesting the direct incorporation of some media-borne amino acids into cellular protein. These observations provide a foundation for understanding the cellular routing of hydrogen obtained from food and water sources and indicate that D/H analysis can serve as a powerful probe of biological function.

  9. Project governance: "Schools of thought"

    Michiel Christiaan Bekker

    2014-02-01

    Full Text Available The terminology, definition and context of project governance have become a focal subject for research and discussions in project management literature. This article reviews literature on the subject of project governance and categorise the arguments into three schools of thought namely the single-firm school, multi-firm school and large capital school. The single-firm school is concerned with governance principles related to internal organisational projects and practice these principles at a technical level. The multi-firm school address the governance principles concerned with two of more organisations participating on a contractual basis on the same project and focus their governance efforts at the technical and strategic level. The large capital school consider projects as temporary organisations, forming their own entity and establishing governance principles at an institutional level. From these schools of thought it can be concluded that the definition of project governance is dependent on the type of project and hierarchical positioning in the organisation. It is also evident that further research is required to incorporate other governance variables and mechanisms such as transaction theory, social networks and agency theory. The development of project governance frameworks should also consider the complexity of projects spanning across international companies, across country borders and incorporating different value systems, legal systems, corporate governance guidelines, religions and business practices.

    Reflective writing in medical training has been shown to be most effective when combined with some form of personal meeting or dialog. During a course in medical psychology for medical students, reflective texts were followed up by an individual personal talk with a teacher from the course. Thematic analysis of the texts revealed four separate sub-themes: 1) the course has enabled me and the class to develop, which is good albeit arduous; 2) understanding myself is a resource in understanding people as well as knowing psychology; 3) the course provided me with new, purely intellectual skills as well as eye-openers; and 4) the receiving teacher is an integral part of my reflective writing. The main theme, capturing the students' writing process, concluded that students perceive the course as "Learning psychology as a challenging process towards development" as well as "studies as usual". Ethical, psychological, and pedagogical aspects are discussed in the paper.

    To propose the Trial-Based Thought Record, a modified, 7-column thought record addressing core beliefs by sentence reversion and the analogy to a trial. Clients (n = 30) participated in a simulation of a trial and exhibited shifts in their adherence to core beliefs and in the intensity of corresponding emotions after each step (investigation, prosecutor s plea, defense attorney s plea, prosecutor s second plea, defense attorney s second plea, and jury verdict) during a session. Significant mean reductions existed between percent values after investigation (taken as baseline) and defense attorney s plea (p < 0.001), and after the jury s verdict, either in beliefs (p < 0.001) or in intensity of emotions (p < 0.001). Significant differences also emerged between the defense attorney s first and second pleas (p = 0.009) and between the defense attorney s second plea and jury s verdict concerning core beliefs (p = 0.005) and emotions (p = 0.02). Trial-Based Thought Record may at least temporarily help patients constructively reduce attachment to negative core beliefs and corresponding emotions.

    Reflective learning entails a thoughtful learning process through which one not only learns a particular piece of knowledge or skill, but better understands "how" one learned it--knowledge that can then be transferred well beyond the scope of the specific learning experience. This type of thinking empowers learners by making them more…

    Reports on a study of the impact of metacognition among 10 middle school-aged British students with learning difficulties. Finds that student awareness and subsequent control over thought processes were enhanced through self-reporting and self-appraisal. Examines this kind of reflection on enhanced learning capabilities and self-esteem. (CFR)

  1. The neural evidence of the reflected appraisal process as a main path for learning about one's self-knowledge of personality.

    Self-knowledge has been defined as the accurate self-perceptions about how one typically thinks, feels, and behaves, and awareness of how those patterns are interpreted by others. Previous research has noted that the introspection and the reflected appraisal processes are two main avenues for learning about the self and that self-knowledge might be fully realized through the use of reflected appraisal from close others. However, due to the methodological difficulty in linking people's ratings on a trait to their behaviors, accuracy research using a behavioral criterion is quite limited. The current work examined the main source of learning about one's self-knowledge by investigating the time course of attention deployment both in the process of introspection and that of reflected appraisal. Twenty-five college students were first asked to rate their impressions of their classmates as well as a familiar other using personality-trait adjectives. Their electrophysiological data were then collected using the event-related potential (ERP) technology while they judged to which extent (1) an adjective can describe the self, (2) an adjective can describe a familiar other, (3) they agree with an adjective that their classmates believe can describe the self, and (4) they agree with an adjective that their classmates believe can describe a familiar other. Our electrophysiological data showed that classmates' positive evaluation of one's own trait elicited larger P2 than the positive self-evaluation of one's own trait. Further, classmates' negative evaluation of one's own trait elicited larger late positive component (LPC) than the negative self-evaluation of one's own trait. Results suggest that people allocate more attention to the process of reflected appraisal compared to the process of introspection, which further suggests that the reflected appraisal process might be the main source in learning about one's self-knowledge of personality.

  2. Psychopathology and Thought Suppression: A Quantitative Review

    Science.gov (United States)

    Magee, Joshua C.; Harden, K. Paige; Teachman, Bethany A.

    2012-01-01

    Recent theories of psychopathology have suggested that thought suppression intensifies the persistence of intrusive thoughts, and proposed that difficulty with thought suppression may differ between groups with and without psychopathology. The current meta-analytic review evaluates empirical evidence for difficulty with thought suppression as a function of the presence and specific type of psychopathology. Based on theoretical proposals from the psychopathology literature, diagnosed and analogue samples were expected to show greater recurrence of intrusive thoughts during thought suppression attempts than non-clinical samples. However, results showed no overall differences in the recurrence of thoughts due to thought suppression between groups with and without psychopathology. There was, nevertheless, variation in the recurrence of thoughts across different forms of psychopathology, including relatively less recurrence during thought suppression for samples with symptoms of Obsessive-Compulsive Disorder, compared to non-clinical samples. However, these differences were typically small and provided only mixed support for existing theories. Implications for cognitive theories of intrusive thoughts are discussed, including proposed mechanisms underlying thought suppression. PMID:22388007

    You can’t really prepare an abstract of a concluding-remarks talk, but having spent 19 years, 8 months as a full time student (Sept. 1948, Toluca Lake Grammar School kindergarten to April 1968 Caltech Ph.D.), most of the ensuing 48 years as a teacher, and about 51 years as some sort of astronomer, I find myself woefully ignorant of astronomy education and therefore well prepared to bring a fresh and vacant mind to the ideas presented by our colleagues here. Several thoughts, however, intrude. First, as Cecilia Payne Gaposchkin said, “a woman should do astronomy only if nothing else will satisfy her, for nothing else is what she will get.” Make that “person” and “science” and it still carries much truth. Second, it is better to be a professional astronomer and an amateur alto than the converse. And third, it is better to be a professional dentist and an amateur astronomer than the converse. This, I think, leaves room for all of us to work in areas that we find attractive and that we turn out to be reasonably good at. The latter is at least as important as the former. There is a great deal of pleasure to be found as a second-rate singer or artist, but not, I hope, as a lousy astronomer or teacher.

  6. Thoughts on the nude body

    2016-07-01

    Full Text Available The image of nude appears to have ‘moved’, both because of the shift in our gaze and its point of reference. That is, unless this ‘negative emphasis’ is seen only as the uncri­ti­cal acceptance of that ‘polarizing question’ that declared the end of Clas­sical art and the decisive advent of modernity or as the effect of an hermeneutic excess ‒ of a philosophical definition of the nude impli­cit in our figurative culture – is it now the moment to go beyond the observation of the canonic nude and to develop new approaches to nudity? Despite its obviousness, the nude, too, is difficult to define. Where does the garment begin and the gown end? The skin and the flesh? How are we to describe the for­ces, movements and gestures of the body and its involucres? I will argue that the nude should be neither a pictorial genre nor a philosophical concept, but a «thought of the body» (De Chirico. It is an aesthetic figure with the power of affection and perception, but also a conceptual figure. It is not a ‘critical operator’ ‒ a cognitive ‘walk-on’ or extra ‒ but an actor with the power of speech, capable of forming and transforming new relationships with observers.

    2016-06-01

    Full Text Available Education for youngsters and adults (in Spanish, EPJA has reached prominence in the Chilean educational system. It has had to give a new chance to a large number of young people who, for one reason or another, did not complete their studies in traditional training. In this scenario, it explores pedagogical practices developed by teachers working with youngsters and adults, especially those who refer to learning assessment. Therefore, the purpose of this study is to present the results of a reflection carried out by a group of teachers from a comprehensive adult education center, in order to improve their practices to evaluate their students’ learning. The research model is based on the qualitative approach with a case study design. It makes a comprehensive diagnostic of teaching practices, conducted through discussion groups. The analysis of the results shows that most teachers working at this educational center follow traditional assessment practices. They tend to copy conceptions of assessment centered around products that can be scored in order to check goal achievement, rather than around providing feedback that promotes self-regulated learning. However, the reflection also shows that teachers are willing to participate in pedagogical reflection sessions that guide them to improve their assessment practices.

    Let n>=2 be identical rockets: R1 ,R2 , ..., Rn. Each of them moving at constant different velocities respectively v1, v2, ..., vn on parallel directions in the same sense. In each rocket there is a light clock, the observer on earth also has a light clock. All n + 1 light clocks are identical and synchronized. The proper time Δt' in each rocket is the same. Let's focus on two arbitrary rockets Ri and Rjfrom the previous n rockets. Let's suppose, without loss of generality, that their speeds verify virocket Rj is contracted with the factor C(vj -vi) , i.e. Lj =Lj' C(vj -vi) .(2) But in the reference frame of the astronaut in Rjit is like rocket Rjis stationary andRi moves with the speed vj -vi in opposite direction. Therefore, similarly, the non-proper time interval as measured by the astronaut inRj with respect to the event inRi is dilated with the same factor D(vj -vi) , i.e. Δtj . i = Δt' D(vj -vi) , and rocketRi is contracted with the factor C(vj -vi) , i.e. Li =Li' C(vj -vi) .But it is a contradiction to have time dilations in both rockets. (3) Varying i, j in {1, 2, ..., n} in this Thought Experiment we get again other multiple contradictions about time dilations. Similarly about length contractions, because we get for a rocket Rj, n-2 different length contraction factors: C(vj -v1) , C(vj -v2) , ..., C(vj -vj - 1) , C(vj -vj + 1) , ..., C(vj -vn) simultaneously! Which is abnormal.

During a course in medical psychology for medical students, reflective texts were followed up by an individual personal talk with a teacher from the course. Thematic analysis of the texts revealed four separate sub-themes: 1 the course has enabled me and the class to develop, which is good albeit arduous; 2 understanding myself is a resource in understanding people as well as knowing psychology; 3 the course provided me with new, purely intellectual skills as well as eye-openers; and 4 the receiving teacher is an integral part of my reflective writing. The main theme, capturing the students’ writing process, concluded that students perceive the course as “Learning psychology as a challenging process towards development” as well as “studies as usual”. Ethical, psychological, and pedagogical aspects are discussed in the paper. Keywords: reflective writing, self-knowledge, individual personal talks, thematic analysis, medical education

    Using fMRI, we investigated the functional organization of prefrontal cortex (PFC) as participants briefly thought of a single just-experienced item (i.e., refreshed an active representation). The results of six studies, and a meta-analysis including previous studies, identified regions in left dorsolateral, anterior, and ventrolateral PFC associated in varying degrees with refreshing different types of information (visual and auditory words, drawings, patterns, people, places, or locations). In addition, activity increased in anterior cingulate with selection demands and in orbitofrontal cortex when a nonselected item was emotionally salient, consistent with a role for these areas in cognitive control (e.g., overcoming "mental rubbernecking"). We also found evidence that presenting emotional information disrupted an anterior component of the refresh circuit. We suggest that refreshing accounts for some neural activity observed in more complex tasks, such as working memory, long-term memory, and problem solving, and that its disruption (e.g., from aging or emotion) could have a broad impact.

    During 1984, over 2300 km of multichannel seismic-reflection data were recorded by the U.S. Geological Survey in the western Ross Sea and Iselin Bank regions.  A temporary loss and sinking of the streamer led to increasing the streamer tow depth to 20 m, which resulted in some attenuation of frequencies in the 30-50 Hz range but no significant difference in resolution of the stacked data.  Severe water bottom multiples were encountered and removed by dip-filtering, weighted stacking, and severe post-NMO muting.

    Regardless of the area of deficiency, be it in knowledge, skills or attitudes, residents requiring remediation are rarely self-identified. This illustrates a diminished ability for self-reflection. Self-reflection is a cornerstone of adult education. During the remediation process, the remediation curriculum needs to emphasize self-reflection. How can one structure self-reflection in a remediation curriculum? This article describes how to adapt and apply environmental scanning for remedial residents. Environmental scanning is a rigorous and well-developed business approach that can be adapted for personal continuous quality improvement to foster self-reflection in medical trainees. There are often already existing tools which can form the foundation for regular reflection in medical education using an environmental scanning structure. Environmental scanning can be thought of as a structured approach to internal and external reflections.

    Many objectification phenomena can be understood from a mind-body dualism perspective in which the more people focus on their bodies, the less they focus on their minds. Instead of viewing mind and body in opposition to each other, we advocate for a more reciprocal view in which mind and body work in conjunction. Consistent with an integrated mind-body approach, we begin our review by describing research on embodied persuasion revealing that focusing on our own body can reduce but also increase thinking (elaboration), as well as affecting the use of thoughts in forming evaluations (validation). Next, we extend our integrated view to a new domain and suggest that physical objects can influence thoughts and that one's thoughts can also be objectified. The first portion of this section focuses on research on enclothed cognition revealing that wearing physical objects can operate through the same processes of elaboration (increasing and decreasing thinking) and validation (increasing and decreasing thought usage) as the body. The second portion reveals that thoughts can be understood and treated as if they were physical objects affecting evaluative processes by influencing elaboration and validation processes. The final section provides some practical guidance relevant to campaigns designed to reduce the objectification of women and the infrahumanization of stigmatized groups. © 2017 The British Psychological Society.

    As part of an ongoing study, seismic-reflection profiles were collected over the Blake Ridge in 1992 and 1995, in order to map the volume and distribution of methane hydrate. Faulting and seafloor instabilities appear to be related to methane hydrate processes at the Blake Ridge. Seismic profiles display a prominent collapse structure at the crest, which is inferred to have resulted from the mobilization of sediment that was associated with methane hydrate dissociation.

    A photovoltaic module includes colorized reflective photovoltaic cells that act as pixels. The colorized reflective photovoltaic cells are arranged so that reflections from the photovoltaic cells or pixels visually combine into an image on the photovoltaic module. The colorized photovoltaic cell or pixel is composed of a set of 100 to 256 base color sub-pixel reflective segments or sub-pixels. The color of each pixel is determined by the combination of base color sub-pixels forming the pixel. As a result, each pixel can have a wide variety of colors using a set of base colors, which are created, from sub-pixel reflective segments having standard film thicknesses.

    Full Text Available In cognitive science, the discussion about the relations between language and thought is very heterogeneous. It involves developments on linguistics, philosophy, psychology, etc. Carruthers and Boucher (1998 identify different criteria that would organize the diversity of positions about language and thought assumed in linguistics, philosophy and psychology. One of them is the constitution thesis (CT, which establishes that language is constitutively involved in thought. In this paper I would like to show some problems of CT in order to understand the relation between language and thought in cognitive science.

    2013-11-01

    Full Text Available A core aspect of human cognition involves overcoming the constraints of the present environment by mentally simulating another time, place, or perspective. Although these self-generated processes confer many benefits, they can come at an important cost, and this cost is greater for some individuals than for others. Here we explore the possibility that the costs and benefits of self-generated thought depend, in part, upon its phenomenological content. To test these hypotheses, we first developed a novel thought sampling paradigm and explored normative ratings of multiple thought content variables (i.e. valence, specificity, self-relevance, etc. across a large sample of young adults. Next, we examined multi-level relationships among these content variables, and used a hierarchical clustering approach to partition self-generated thought into multiple dimensions. Finally, we investigated whether these content dimensions predicted individual differences in the costs and benefits of the experience, assessed with questionnaires measuring emotional health and wellbeing. Individuals who characterized their thoughts as more negative and more personally-significant exhibited scored higher on constructs associated with Depression and Trait Negative Affect, whereas those who characterized their thoughts as less specific scored higher on constructs linked to Rumination. In contrast, individuals who characterized their thoughts as more positive, less personally-significant, and more specific scored higher on constructs linked to improved wellbeing (Mindfulness. Collectively, these findings suggest that the content of people’s inner thoughts can 1 be productively examined, 2 be distilled into several major dimensions, and 3 account for a large portion of variability in their functional outcomes.

    Full Text Available Theoretical, computational and experimental studies have converged to a model of decision-making in which sensory evidence is stochastically integrated to a threshold, implementing a shift from an analog to a discrete form of computation. Understanding how this process can be chained and sequenced - as virtually all real-life tasks involve a sequence of decisions - remains an open question in neuroscience. We reasoned that incorporating a virtual continuum of possible behavioral outcomes in a simple decision task- a fundamental ingredient of real-life decision making – should result in a progressive sequential approximation to the correct response. We used real-time tracking of motor action in a decision task, as a measure of cognitive states reflecting an internal decision process. We found that response trajectories were spontaneously segmented into a discrete sequence of explorations separated by brief stops (about 200 ms – which remained unconscious to the participants. The characteristics of these stops were indicative of a decision process - a moment of thought: their duration correlated with the difficulty of the decision and with the efficiency of the subsequent exploration. Our findings suggest that simple navigation in an abstract space involves a discrete sequence of explorations and stops and, moreover, that these stops reveal a fingerprint of moments of thought.

    Full Text Available The Aristotelic Logic, which is characterized by four laws, is commonly accepted as being representative of normal though, when considered in its formal aspect. Arieti defends the existence of another logic, one that he has designated "Paleological", which was dominant in human beings in the beginning of their evolution, and that also occurs in certain characteristics of infantile thought, as well as in the primary process (manner in which the unconscious operates. The same author considers that this logic, whoch is quiescent, emerges in schizophrenic thought, dominating and overlapping the Aristotelian logic. In order to escape from anguish, the shizophrenic patient abandons Aristotelian norms of thought and adopts the Paleological form, because by interpreting reality, in light of Aristotelian logic, it's felt to be threatening and unbearable. Finally, Arieti explains that the principles of Paleological thought don't explain the phenomenon dynamically, merely formally. The study of psychodinamic mechanisms reveals what and why (content and motivation, while the study of formal mechanims reveal how, thoughts and feelings are processed.

  7. Disruption of visual awareness during the attentional blink is reflected by selective disruption of late-stage neural processing

    2015-01-01

    Any information represented in the brain holds the potential to influence behavior. It is therefore of broad interest to determine the extent and quality of neural processing of stimulus input that occurs with and without awareness. The attentional blink is a useful tool for dissociating neural and behavioral measures of perceptual visual processing across conditions of awareness. The extent of higher-order visual information beyond basic sensory signaling that is processed during the attentional blink remains controversial. To determine what neural processing at the level of visual-object identification occurs in the absence of awareness, electrophysiological responses to images of faces and houses were recorded both within and outside of the attentional blink period during a rapid serial visual presentation (RSVP) stream. Electrophysiological results were sorted according to behavioral performance (correctly identified targets versus missed targets) within these blink and non-blink periods. An early index of face-specific processing (the N170, 140–220 ms post-stimulus) was observed regardless of whether the subject demonstrated awareness of the stimulus, whereas a later face-specific effect with the same topographic distribution (500–700 ms post-stimulus) was only seen for accurate behavioral discrimination of the stimulus content. The present findings suggest a multi-stage process of object-category processing, with only the later phase being associated with explicit visual awareness. PMID:23859644

    Full Text Available The Colegio Pedro II was equated to Federal Institutes of Education, Science and Technology by Law 12677 Publication of June 25, 2012. If, on the one hand, this equalization resulted in an expressive organizational restructuring, with growth of the number of educational units, in addition to the incorporation of new educational levels, on the other, this institutional growth was dissociated from efforts of standardization of administrative processes, notably, under the academic departments of different units – where it shows a variation of the process of launching notes/concepts. In order to contribute with improvements to the operation of the institution, the present article aims to map and analyse comparatively the launch process of notes/concepts in three campus of the Colegio Pedro II. Methodologically, are held in-person interviews with professionals responsible for the academic departments of the following units, Engenho Novo I, Humaita I and Realengo I, in order to obtain the necessary subsidies to support the design of the processes performed by these academic departments units. As a result, it can be verified that the processes of the academic departments are not aligned to any system of performance indicators, which motivated the proposal of a standard process for the launching of notes/concepts, as well as a performance indicators panel (KPIs.

Studying T Tauri stars is important for understanding the early stages of star formation and how planetary systems are created. Remarkably, this complex of nebulae has also changed significantly in the last ten years. In February 2004 the experienced amateur observer Jay McNeil took an image of this region with a 75 mm telescope and was surprised to see a bright nebula - the prominent fan shaped feature near the bottom of this picture - where nothing was seen on most earlier images. This object is now known as McNeil's Nebula and it appears to be a highly variable reflection nebula around a young star. This colour picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through an H-alpha filter that shows light from glowing hydrogen gas. The total exposure times were 9, 9, 17.5 and 15.5 minutes per filter, respectively. Notes [1] Igor Chekalin from Russia uncovered the raw data for this image of Messier 78 in ESO's archives in the competition Hidden Treasures (eso1102). He processed the raw data with great skill, claiming first prize in the contest for his final image (Flickr link). ESO's team of in-house image processing experts then independently processed the raw data at full resolution to produce the image shown here.

    ABSTRACT ADHD can be considered an internationally recognized framework for understanding children’s restlessness. In this context, children’s restlessness is understood as a symptom of neurodevelopmental disorder. However, there are other possible understandings of children’s restlessness. In this article, we explore four boys’ collaborative and creative process as it is described and understood by three adults. The process is framed by a community music therapy project in a Norwegian kindergarten, and we describe four interrelated phases of this process: Exploring musical vitality and cooperation, Consolidating positions, Performing together, and Discovering ripple effects. We discuss these results in relation to seven qualities central to a community music therapy approach: participation, resource orientation, ecology, performance, activism, reflexivity and ethics. We argue that in contrast to a diagnostic approach that entails a focus on individual problems, a community music therapy approach can shed light on adult and systemic contributions to children’s restlessness.

  3. Formal Thought Disorder and language impairment in schizophrenia

    Directory of Open Access Journals (Sweden)

    Marcia Radanovic

    2013-01-01

    Full Text Available Schizophrenia is a psychiatric illness in which disorders of thought content are a prominent feature. The disruption of normal flow of thought, or “Formal Thought Disorder” (FTD, has been traditionally assessed through the content and form of patients’ speech, and speech abnormalities in schizophrenia were considered as a by-product of the disruption in conceptual structures and associative processes related to psychosis. This view has been changed due to increasing evidence that language per se is impaired in schizophrenia, especially its semantic, discursive, and pragmatic aspects. Schizophrenia is currently considered by some authors as a “language related human specific disease” or “logopathy”, and the neuroanatomical and genetic correlates of the language impairment in these patients are under investigation. Such efforts may lead to a better understanding about the pathophysiology of this devastating mental disease. We present some current concepts related to FTD as opposed to primary neurolinguistic abnormalities in schizophrenia.

  4. Brain mechanisms for loss of awareness of thought and movement

    Abstract Loss or reduction of awareness is common in neuropsychiatric disorders and culturally influenced dissociative phenomena but the underlying brain mechanisms are poorly understood. fMRI was combined with suggestions for automatic writing in 18 healthy highly hypnotically suggestible individuals in a within-subjects design to determine whether clinical alterations in awareness of thought and movement can be experimentally modelled and studied independently of illness. Subjective ratings of control, ownership, and awareness of thought and movement, and fMRI data were collected following suggestions for thought insertion and alien control of writing movement, with and without loss of awareness. Subjective ratings confirmed that suggestions were effective. At the neural level, our main findings indicated that loss of awareness for both thought and movement during automatic writing was associated with reduced activation in a predominantly left-sided posterior cortical network including BA 7 (superior parietal lobule and precuneus), and posterior cingulate cortex, involved in self-related processing and awareness of the body in space. Reduced activity in posterior parietal cortices may underlie specific clinical and cultural alterations in awareness of thought and movement. Clinically, these findings may assist development of imaging assessments for loss of awareness of psychological origin, and interventions such as neurofeedback. PMID:28338742

    Full Text Available This paper is based on the development and results of the research project ‘School ecosystems for the development of children’s creative thought’, which has been being implemented under Action Research parameters since 2010. Its purpose is to design and carry out some pedagogical strategies leading to creative thought development in third, fourth and fifth grade children belonging to Technical School Rafael Uribe, Leonera headquarters, in the municipality of Toca, Department of Boyaca. The project is based on the Ecological Model for Human Development formulated by Urie Bronfenbrenner, Eduard de Bono´s creative thought basis, George Polya’s problem solving method, and the Philosophy for Children proposal stated by Matthew Lipman and promoted in Colombia by Diego Pineda. Those approaches are understood as cross-wise themes leading children to a reflection, creation, argumentation, and analysis process when facing the designed settings (ideas inventor, Math and recreation, Technological Curiosity, and Life Crops established individually in terms of time and actions, which have made possible to transform the ways of thinking and acting of those taking part in the pedagogical process through questions that guide the everyday duties and the scope of education aims.

  6. The solonetzic process in surface soils and buried paleosols and its reflection in the mineralogical soil memory

    The development of the solonetzic process in paleosols buried under kurgans and in the modern surface soils has been studied on the basis of the analysis of the clay (memory“ of the solid-phase soil components. The mineralogical characteristics show that the solonetzic process in the modern background soil is more developed. The mineralogical approach allows us to reveal the long-term changes in the soil status; it is less useful for studying the effect of short-term bioclimatic fluctuations. In the latter case, more labile soil characteristics should be used. The mineralogical method, combined with other methods, becomes more informative upon the study of soil chronosequences. Our studies have shown that the data on the clay minerals in the buried paleosols may contain specific information useful for paleoreconstructions that is not provided by other methods.

    Despite the fact that physical health and cognitive abilities decline with aging, the ability to regulate emotion remains stable and in some aspects improves across the adult life span. Older adults also show a positivity effect in their attention and memory, with diminished processing of negative stimuli relative to positive stimuli compared with younger adults. The current paper reviews functional magnetic resonance imaging studies investigating age-related differences in emotional processing and discusses how this evidence relates to two opposing theoretical accounts of older adults’ positivity effect. The aging-brain model [Cacioppo et al. in: Social Neuroscience: Toward Understanding the Underpinnings of the Social Mind. New York, Oxford University Press, 2011] proposes that older adults’ positivity effect is a consequence of age-related decline in the amygdala, whereas the cognitive control hypothesis [Kryla-Lighthall and Mather in: Handbook of Theories of Aging, ed 2. New York, Springer, 2009; Mather and Carstensen: Trends Cogn Sci 2005;9:496–502; Mather and Knight: Psychol Aging 2005;20:554–570] argues that the positivity effect is a result of older adults’ greater focus on regulating emotion. Based on evidence for structural and functional preservation of the amygdala in older adults and findings that older adults show greater prefrontal cortex activity than younger adults while engaging in emotion-processing tasks, we argue that the cognitive control hypothesis is a more likely explanation for older adults’ positivity effect than the aging-brain model.

  10. Consciousness across Sleep and Wake: Discontinuity and Continuity of Memory Experiences As a Reflection of Consolidation Processes

    Directory of Open Access Journals (Sweden)

    Caroline L. Horton

    2017-09-01

    Full Text Available The continuity hypothesis (1 posits that there is continuity, of some form, between waking and dreaming mentation. A recent body of work has provided convincing evidence for different aspects of continuity, for instance that some salient experiences from waking life seem to feature in dreams over others, with a particular role for emotional arousal as accompanying these experiences, both during waking and while asleep. However, discontinuities have been somewhat dismissed as being either a product of activation-synthesis, an error within the consciousness binding process during sleep, a methodological anomaly, or simply as yet unexplained. This paper presents an overview of discontinuity within dreaming and waking cognition, arguing that disruptions of consciousness are as common a feature of waking cognition as of dreaming cognition, and that processes of sleep-dependent memory consolidation of autobiographical experiences can in part account for some of the discontinuities of sleeping cognition in a functional way. By drawing upon evidence of the incorporation, fragmentation, and reorganization of memories within dreams, this paper proposes a model of discontinuity whereby the fragmentation of autobiographical and episodic memories during sleep, as part of the consolidation process, render salient aspects of those memories subsequently available for retrieval in isolation from their contextual features. As such discontinuity of consciousness in sleep is functional and normal.

    When completed, the National Ignition Facility (NIF) will provide laser energies in the Mega-joule range. Successful pulse amplification to these extremely high levels requires that all small optics, found earlier in the beamline, have stringent surface and laser fluence requirements. In addition, they must operate reliably for 30 years constituting hundreds of thousands of shots. As part of the first four beamlines, spherical and aspherical lenses were required for the beam relaying telescopes. The magneto-rheological technique allows for faster and more accurate finishing of aspheres. The spherical and aspherical lenses were final figured using both conventional-pitch polishing processes for high quality laser optics and the magneto-rheological finishing process. The purpose of this paper is to compare the surface properties between these two finishing processes. Some lenses were set aside from production for evaluation. The surface roughness in the mid-frequency range was measured and the scatter was studied. Laser damage testing at 1064 nm (3-ns pulse width) was performed on surfaces in both the uncoated and coated condition.

    In this paper the replication qualities of periodically and randomly arranged micro-features molded in the injection molding process and their effects on surface properties are studied. The features are molded in PC, PMMA and PP at different mold wall temperatures in order to point out the necessity and profitability of a variotherm mold wall temperature control system. A one-dimensional heat conduction model is proposed to predict the cycle times of the variotherm injection molding processes. With regard to these processes, the molding results are compared to the molded surface feature heights using an atomic force microscope. In addition, the effects of the molded surface features on macroscopic surfaces are characterized in terms of light reflection using a spectrometer and in terms of water wettability by measuring the static contact angle. Furthermore, due to the sensitivity of the surface features on the molded parts, their durability is compared in a scratch test with a diamond tip. This leads to successful implementation in applications in which the optical appearance, in terms of gloss and reflection, and the water repellence, in terms of drag flow and adhesion, are of importance.

    This is a report of an interview between the 'Energia Nucleara' reporter and Mr David S. Harris, the AECL project director for Cernavoda NPP Unit 2. The following items were addressed during the interview: the status of the Cernavoda NPP Unit 2 project; the differences in the project between Unit 1 and Unit 2; the Romanian infrastructure and industrial contributions to the Unit 2 project; the cooperation with Romanian design team; the Canadian authorities support to Unit 2 completion; Unit 3 project and AECL possible involvement. Following the Romanian Government's decision to complete Cernavoda Unit 2 in late 2002 work was recommenced in the key areas of engineering, procurement of equipment and materials signing of major supply contracts and construction, such that the total project is now 52% complete. actual construction activities are now 41% complete, and the number of key milestones have recently been achieved, such as: Closure of the Reactor Building 'B' Opening; commencement of rolling in of 45,000 main turbine condenser tubes; commencement of post-tensioning works on the Reactor Building structure and the completion of various infrastructure civil works. Structures and equipment already delivered, and installed or stored are in good conditions and ready for construction continuation. The following changes were implemented in Unit 2 as compared to Unit 1: design changes to meet new regulations and provide increases in the margin of safety; changes due to development of nuclear technology, particularly those improving performance and reliability of operation; design changes to replace equipment affected by obsolescence to allow purchasing of spare parts in the future. Concerning the future, AECL is willing to cooperate with the Romanian SNN on the Unit 3 completion process

    One appears in the communication as one resorts for the social mobilization, towards the political pretensions of the messianic environmental thought, to symbiologies of body, psychic character and society of skeptical or relativist character. For the analysis of the symbiologies, we start from the criterion that when they are used politically in the environmental thought it is not done necessarily with an intention of strategic use I specify, but that its use can be by the implicit valuations that have these symbiologies in the world of the daily life, where the systems of environmental thought also interact of messianic type

    2017-09-01

    Choice is a behavioral act that has a variety of well-documented motivational consequences-it fosters independence by allowing people to simultaneously express themselves and influence the environment. Given the link between independence and analytic thinking, the current research tested whether choice also leads people to think in a more analytic rather than holistic manner. Four experiments demonstrate that making choices, recalling choices, and viewing others make choices leads people to think more analytically, as indicated by their attitudes, perceptual judgments, categorization, and patterns of attention allocation. People who made choices scored higher on a subjective self-report measure of analytic cognition compared to whose did not make a choice (pilot study). Using an objective task-based measure, people who recalled choices rather than actions were less influenced by changes in the background when making judgments about focal objects (Experiment 1). People who thought of others' behaviors as choices rather than actions were more likely to group objects based on categories rather than relationships (Experiment 2). People who recalled choices rather than actions subsequently allocated more visual attention to focal objects in a scene (Experiment 3). Together, these experiments demonstrate that choice has important yet previously unexamined consequences for basic psychological processes such as attention and cognition.

    Full Text Available Two experiments examined the benefits of unconscious thought on complex decisions (Dijksterhuis, 2004. Experiment 1 attempted to replicate and extend past research by examining the effect of providing reasons prior to rating the options. Results indicated no significant differences between the conditions. Experiment 2 attempted to replicate the findings of Dijksterhuis, Bos, Nordgren, and van Baaren (2006 and determine if a memory aid could overcome the limitations of conscious thought on complex tasks. Results revealed that a memory aid improved decisions compared to the conscious thought condition. Participants in the unconscious thought condition did not perform significantly better than did participants in the conscious thought condition.

    Full Text Available Here are some loud thoughts that reflect upon the relationship that had long existed amidst philosophy, religion and economics in the so-called ‘grand’ civilizations (that had existed during 3100 BC to the beginning of Christian era. Historically, the visions of intellectuals, rulers, men of faiths, and business people have helped drive these civilizations to their zenith. The philosophies, religions, and economics of the time were deeply involved in this process of development, and seem to have acted in unison. Here is an attempt to provoke some fresh thinking on the subject by re-examining this triad relationship of the fundamental spheres of human life. The logic of this paper attempts to raise doubts, if the relationship was ideal and was based on ethical and moral values, as it was proclaimed by the philosophers, pontiffs, politicians and the business leaders of the time.

    Full Text Available We proposed a low-cost and highly reflective liquid organic sheet silver conductor using back contact reflectors in amorphous silicon (a-Si single junction superstrate configuration thin-film solar cells produced using a nonvacuum screen printing process. A comparison of silver conductor samples with vacuum-system-sputtered silver samples indicated that the short-circuit current density (Jsc of sheet silver conductor cells was higher than 1.25 mA/cm2. Using external quantum efficiency measurements, the sheet silver conductor using back contact reflectors in cells was observed to effectively enhance the light-trapping ability in a long wavelength region (between 600 nm and 800 nm. Consequently, we achieved an optimal initial active area efficiency and module conversion efficiency of 9.02% and 6.55%, respectively, for the a-Si solar cells. The results indicated that the highly reflective sheet silver conductor back contact reflector layer prepared using a nonvacuum process is a suitable candidate for high-performance a-Si thin-film solar cells.

    Full Text Available The available data on well-studied areas of the Turan platform (as an example are reviewed and analyzed to reveal the role of con-sedimentation and post-sedimentation tectonic movements in formation of dislocations of the sedimentary cover. At the background of the long-term (tens and hundreds of million years quiet evolution of the territory under study, short-term intervals are distinguished, which duration amounts to the first millions of years (typically manifested in one or two stratigraphic layers; in such time intervals, tectonic movements were dramatically boosted and accompanied by land uplifting, sea regression, erosion of sediments accumulated earlier and manifestation of deformation processes.The paleotectonic reconstructions show that during such ‘revolutionary’ stages, large tectonic elements occurred along with local uplifts that added to their complexity. In the region under study, the Pre-Jurassic, Pre-Cretaceous (Late Okoma, Pre-Danish and the Pre-Middle Miocene gaps in sedimentation are studied in detail. It is shown that only during the above four periods of sedimentation gaps and accompanying erosion-denudation processes, the regional structures gained from 50 to 80% of their current amplitudes at the bottom of the cover, and the Pre-Danish and Pre-Middle Miocene washout periods were most important.Local uplift also developed impulsively and primarily due to the post-sedimentation movements. Cross-sections of anticlines studied in detail (Figures 1 to 3 are discussed as examples that clearly show the increase of erosional shearing of the sediments accumulated earlier towards domes of uplifts without any con-sedimentation decrease of their thicknesses. During these periods of the geologic history, regardless of their short duration, folded dislocation gained up to 65–90% of their current amplitudes. The periods of activation were separated by long relatively quiescent tectonic periods with the gradually slowing down

    It has been suggested that some aspects of mental state understanding recruit a rudimentary, but fast and efficient, processing system, demonstrated by the obligatory slowing down of judgements about what the self can see when this is incongruent with what another can see. We tested the social nature of this system by investigating to what extent these altercentric intrusions are elicited under conditions that differed in their social relevance and, further, how these related to self-reported social perspective taking and empathy. In Experiment 1, adult participants were asked to make "self" or "other" perspective-taking judgements during congruent ("self" and "other" can see the same items) or incongruent conditions ("self" and "other" cannot see the same items) in conditions that were social (i.e., involving a social agent), semisocial (an arrow), or nonsocial (a dual-coloured block). Reaction time indices of altercentric intrusion effects were present across all conditions, but were significantly stronger for the social than for the less social conditions. Self-reported perspective taking and empathy correlated with altercentric intrusion effects in the social condition only. In Experiment 2, the significant correlations for the social condition were replicated, but this time with gaze duration indices of altercentric intrusion effects. Findings are discussed with regard to the degree to which this rudimentary system is socially specialized and how it is linked to more conceptual understanding.

    2006-01-01

    Objective: To introduce the process of journal writing to promote reflection and discuss the techniques and strategies to implement journal writing in an athletic training education curriculum. Background: Journal writing can facilitate reflection and allow students to express feelings regarding their educational experiences. The format of this writing can vary depending on the students' needs and the instructor's goals. Description: Aspects of journal writing assignments are discussed, including different points to take into account before assigning the journals. Lastly, various factors to contemplate are presented when providing feedback to the students regarding their written entries. Clinical Advantages: Journal writing assignments can benefit students by enhancing reflection, facilitating critical thought, expressing feelings, and writing focused arguments. Journal writing can be adapted into a student's clinical course to assist with bridging the gap between classroom and clinical knowledge. In addition, journals can assist athletic training students with exploring different options for handling daily experiences. PMID:16791310

    This chapter presents psychological issues and processes in adolescent patients who have also migrated or relocated from one country to another. Theoretical perspectives related to attachment processes illumine both migration and adolescence as changes for which secure bases are most needed, lost, and sometimes rediscovered. The psychodynamic processes underlying the difficulties encountered by such adolescents, and their meaning, are presented. Relationships with parents, which normally go through separation-individuation and renegotiation of the oedipal crisis, both of which are central to adolescence, are disrupted by migration. Migration poses new challenges and choices while identity formation is evolving during adolescence. These include adopting a new identity, embracing and letting go of the old, and accepting and integrating the new. The dual relationship with identity finds expression, for example, in language. Fluctuations in understanding and not understanding the new and the old language represent the ambivalence toward the new and the old. The developmental roller-coaster of adolescence, which involves more intense use of defense mechanisms, is heightened during immigration. Processes of idealization (of parents, therapist, old country, new culture) rapidly fade with the devaluation of the same targets. Mechanisms of splitting between good and bad, as well as massive repression of issues that are too hard to deal with at this crossroad, are profuse. Hopeful fantasies of rebirth are concurrent with despair, depression, and, in some cases, suicidal thoughts and attempts. Excerpts from a case in psychodynamic psychotherapy are presented, focusing on the evolving new balances: integrating the old and the new by maintaining attachments to the one while forming attachments to the other; relinquishing and mourning the lost paradise of childhood, as well as the old country, friends, culture, smells, and tastes; accepting disappointments when the shining new

    The phenomena preceding the Coronal Mass Ejections (CMEs) and observed in the radio-frequency band represent a lot of sporadic components of the emission, that cover the wide frequency range. The study of these phenomena composes the new, prevailing for the last ten years direction. This is caused by the fact that solar radioastronomy possesses the developed network of observant tools, by the sensitive methods of observations. It makes possible in a number of cases to obtain information from the layers of solar atmosphere, inaccessible for the studies by other methods of observations. The purpose of this work is analysis of information about the CMEs preceding radio-events and their dynamics in the centimeter and decimeter radio emission in 1998. We use the data of the worldwide network of solar observatories in the radio-frequency band, the data about the CMEs phenomena and the characteristics are taken from Internet: http://sdaw.gsfc.nasa.gov./CME_list}. From great number of the CMEs we select only such, before which there were no more recorded events in the time interval of 8 hours, and before which sporadic radio emission was observed on 2-hours interval. The selection of this interval was caused by available study about the mean lifetime of precursors before CMEs and powerful flares, as a rule, accompanying CMEs, in the optical, X-ray and radio emissions. It constitutes, on the average, about 30 min. The total volume of data composed 68 analyzed events of CMEs in 1998. The analysis of the spectral- temporary characteristics of sporadic radio emission in the dependence on the CMEs parameters is carried out. The nature of processes at the stage of formation and initial propagation of CMEs, such as floating up of new magnetic fluxes, the development of instabilities, the characteristic scales of phenomena, that have an effect upon the observed radio emission is analyzed. The work is carried out with the support of Russian Fund of Basic Research (grant 03

    It is well recognized that the default mode network (DMN) is involved in states of imagination, although the cognitive processes that this association reflects are not well understood. The DMN includes many regions that function as cortical "hubs", including the posterior cingulate/retrosplenial cortex, anterior temporal lobe and the hippocampus. This suggests that the role of the DMN in cognition may reflect a process of cortical integration. In the current study we tested whether functional connectivity from uni-modal regions of cortex into the DMN is linked to features of imaginative thought. We found that strong intrinsic communication between visual and retrosplenial cortex was correlated with the degree of social thoughts about the future. Using an independent dataset, we show that the same region of retrosplenial cortex is functionally coupled to regions of primary visual cortex as well as core regions that make up the DMN. Finally, we compared the functional connectivity of the retrosplenial cortex, with a region of medial prefrontal cortex implicated in the integration of information from regions of the temporal lobe associated with future thought in a prior study. This analysis shows that the retrosplenial cortex is preferentially coupled to medial occipital, temporal lobe regions and the angular gyrus, areas linked to episodic memory, scene construction and navigation. In contrast, the medial prefrontal cortex shows preferential connectivity with motor cortex and lateral temporal and prefrontal regions implicated in language, motor processes and working memory. Together these findings suggest that integrating neural information from visual cortex into retrosplenial cortex may be important for imagining the future and may do so by creating a mental scene in which prospective simulations play out. We speculate that the role of the DMN in imagination may emerge from its capacity to bind together distributed representations from across the cortex in a

    We establish an analogy between superconductor-metal interfaces and the quantum physics of a black hole, using the proximity effect. We show that the metal-superconductor interface can be thought of as an event horizon and Andreev reflection from the interface is analogous to the Hawking radiation in black holes. We describe quantum information transfer in Andreev reflection with a final state projection model similar to the Horowitz-Maldacena model for black hole evaporation. We also propose the Andreev reflection analogue of Hayden and Preskill's description of a black hole final state, where the black hole is described as an information mirror. The analogy between crossed Andreev reflections and Einstein-Rosen bridges is discussed: our proposal gives a precise mechanism for the apparent loss of quantum information in a black hole by the process of nonlocal Andreev reflection, transferring the quantum information through a wormhole and into another universe. Given these established connections, we conjecture that the final quantum state of a black hole is exactly the same as the ground state wave function of the superconductor/superfluid in the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity; in particular, the infalling matter and the infalling Hawking quanta, described in the Horowitz-Maldacena model, forms a Cooper pairlike singlet state inside the black hole. A black hole evaporating and shrinking in size can be thought of as the analogue of Andreev reflection by a hole where the superconductor loses a Cooper pair. Our model does not suffer from the black hole information problem since Andreev reflection is unitary. We also relate the thermodynamic properties of a black hole to that of a superconductor, and propose an experiment which can demonstrate the negative specific heat feature of black holes in a growing/evaporating condensate.

    Full Text Available This research was carried out with the aim to analyze the methodological strategy adopted by the coach of the Brazilian youth man volleyball team during training sessions in the preparation period. As a data gathering method, 45 videos were taken during sessions, 28 in Belo Horizonte and 17 in Poços de Caldas. A semi-structured interview was also held with the coach and the coaching staff . The results of the research indicated that the coach’s pedagogical practice was strongly influenced by technical, developmental and systemic methodological conceptions. This practice was developed through a combination of different methodologies, such as analytic, synthetic, structuralist, dynamic and progressive. The relationship between the coaching staff and the athletes was harmonious and respectful. It was shown that, besides to anthropometric, conditioning, technical-coordinating, tactical-cognitive and psychological factors, the twelve athletes who represented Brazil in the World Youth Championshipwere also chosen for other qualities. Among the qualities to be mentioned are the capacity for leadership, group cohesion, courage and determination . The research pointed out that the preparation process of the Brazilian team was carried out with great competence, through a correct division of training time and a careful selection of the athletes, following international standard criteria such as height, strength and individual technical skills.

    Supervision is a basic part of training and ongoing education in cognitive behavioural therapy. Self-reflection is an important part of supervision. The conscious understanding of one's own emotions, feelings, thoughts, and attitudes at the time of their occurrence, and the ability to continuously follow and recognize them are among the most important abilities of both therapists and supervisors. The objective of this article is to review aspects related to supervision in cognitive behavioural therapy and self-reflection in the literature. This is a narrative review. A literature review was performed using the PubMed, SciVerse Scopus, and Web of Science databases; additional references were found through bibliography reviews of relevant articles published prior to July 2011. The databases were searched for articles containing the following keywords: cognitive behavioural therapy, self-reflection, therapeutic relationship, training, supervision, transference, and countertransference. The review also includes information from monographs referred to by other reviews. We discuss conceptual aspects related to supervision and the role of self-reflection. Self-reflection in therapy is a continuous process which is essential for the establishment of a therapeutic relationship, the professional growth of the therapist, and the ongoing development of therapeutic skills. Recognizing one's own emotions is a basic skill from which other skills necessary for both therapy and emotional self-control stem. Therapists who are skilled in understanding their inner emotions during their encounters with clients are better at making decisions, distinguishing their needs from their clients' needs, understanding transference and countertransference, and considering an optimal response at any time during a session. They know how to handle their feelings so that these correspond with the situation and their response is in the client's best interest. The ability to self-reflect increases the

    A classical description of the one dimensional radiative transfer treatment of vegetation canopies was completed and the results were tested against measured prairie (blue grama) and agricultural canopies (soybean). Phase functions are calculated in terms of directly measurable biophysical characteristics of the canopy medium. While the phase functions tend to exhibit backscattering anisotropy, their exact behavior is somewhat more complex and wavelength dependent. A Monte Carlo model was developed that treats soil surfaces with large periodic variations in three dimensions. A photon-ray tracing technology is used. Currently, the rough soil surface is described by analytic functions and appropriate geometric calculations performed. A bidirectional reflectance distribution function is calculated and, hence, available for other atmospheric or canopy reflectance models as a lower boundary condition. This technique is used together with an adding model to calculate several cases where Lambertian leaves possessing anisotropic leaf angle distributions yield non-Lambertian reflectance; similar behavior is exhibited for simulated soil surfaces.

  15. Readiness for self-directed change in professional behaviours: factorial validation of the Self-Reflection and Insight Scale.

    Self-reflection, the practice of inspecting and evaluating one's own thoughts, feelings and behaviour, and insight, the ability to understand one's own thoughts, feelings and behaviour, are central to the self-regulation of behaviours. The Self-Reflection and Insight Scale (SRIS) measures three factors in the self-regulation cycle: need for reflection; engagement in reflection, and insight. We used structural equation modelling to undertake a confirmatory factor analysis of the SRIS. We re-specified our model to analyse all of the data to explain relationships between the SRIS, medical student characteristics, and responses to issues of teaching and learning in professionalism. The factorial validity of a modified SRIS showed all items loading significantly on their expected factors, with a good fit to the data. Each subscale had good internal reliability (> 0.8). There was a strong relationship between the need for reflection and engagement in reflection (r = 0.77). Insight was related to need for reflection (0.22) and age (0.21), but not to the process of engaging in reflection (0.06). Validation of the SRIS provides researchers with a new instrument with which to measure and investigate the processes of self-reflection and insight in the context of students' self-regulation of their professionalism. Insight is related to the motive or need for reflection, but the process of reflection does not lead to insight. Attending to feelings is an important and integral aspect of self-reflection and insight. Effective strategies are needed to develop students' insight as they reflect on their professionalism.

    Thought suppression has spurred extensive research in clinical and preclinical fields, particularly with regard to the paradoxical aspects of this behavior. However, the involvement of the brain's inhibitory system in the dynamics underlying the continuous effort to suppress thoughts has yet to be clarified. This study aims to provide a unified perspective for the volitional suppression of internal events incorporating the current understanding of the brain's inhibitory system. Twenty healthy volunteers underwent functional magnetic resonance imaging while they performed thought suppression blocks alternating with visual imagery blocks. The whole dataset was decomposed by group-independent component analysis into 30 components. After discarding noise components, the 20 valid components were subjected to further analysis of their temporal properties including task-relatedness and between-component residual correlation. Combining a long task period and a data-driven approach, we observed a right-side-dominant, lateral frontoparietal network to be strongly suppression related. This network exhibited increased fluctuation during suppression, which is compatible with the well-known difficulty of suppression maintenance. Between-network correlation provided further insight into the coordinated engagement of the executive control and dorsal attention networks, as well as the reciprocal activation of imagery-related components, thus revealing neural substrates associated with the rivalry between intrusive thoughts and the suppression process.

    Reflection is a fuzzy concept. In this article we reveal the paradoxes involved in studying the nature of reflection. Whereas some scholars emphasize its discursive nature, we go further and underline its resemblance to the self-biased dialogue Socrates had with the slave in Plato's Meno . The individual and internal nature of the reflection process creates difficulty for studying it validly and reliably. We focus on methodological issues and use Hans Linschoten's view of coupled systems to identify, analyze, and interpret empirical research on reflection. We argue that researchers and research participants can take on roles in several possible system couplings. Depending on who controls the manipulation of the stimulus, who controls the measuring instrument, who interprets the measurement and the response, different types of research questions can be answered. We conclude that reflection may be validly studied by combining different couplings of experimenter, manipulation, stimulus, participant, measurement, and response.

    This study examined differences in the appraisal and thought control strategies associated with the perceived control of unwanted sexual and non-sexual intrusive thoughts. Eleven appraisal dimensions, subjective physiological arousal and 10 thought control strategies were measured in 171 university students who were administered the Revised Obsessive Intrusions Inventory-Sex Version, a self-report measure of unwanted intrusive thoughts. Thought-action fusion (TAF) likelihood was a significant unique predictor of the perceived controllability of respondents' most upsetting sexual and non-sexual intrusive thought. Moreover greater subjective physiological arousal was a significant predictor of reduced control over sexual intrusions, whereas worry that one might act on an intrusive thought and greater effort to control the intrusion were significant unique predictors of the control of non-sexual intrusive thoughts. Various thought control strategies were more often used in response to non-sexual than sexual cognitions. The results are discussed in terms of the differential role of various appraisal processes in the control of unwanted sexual and non-sexual thoughts.

    A central question in cognitive science is whether natural language provides combinatorial operations that are essential to diverse domains of thought. In the study reported here, we addressed this issue by examining the role of linguistic mechanisms in forging the hierarchical structures of algebra. In a 3-T functional MRI experiment, we showed that processing of the syntax-like operations of algebra does not rely on the neural mechanisms of natural language. Our findings indicate that processing the syntax of language elicits the known substrate of linguistic competence, whereas algebraic operations recruit bilateral parietal brain regions previously implicated in the representation of magnitude. This double dissociation argues against the view that language provides the structure of thought across all cognitive domains.

    Different psychotherapeutic approaches claim positive changes in patients as a result of therapy. Explanations related to the change process led to different change models. Some of the change models are experimentally oriented whereas some are theoretical. Apart from the core models of behavioral, psychodynamic, humanistic, cognitive and spiritually oriented models there are specific models, within psychotherapy that explains the change process. Integrative theory of a person as depicted in Indian thought provides a common ground for the integration of various therapies. Integrative model of change based on Indian thought, with specific reference to psychological concepts in Upanishads, Ayurveda, Bhagavad Gita and Yoga are presented. Appropriate psychological tools may be developed in order to help the clinicians to choose the techniques that match the problem and the origin of the dimension. Explorations have to be conducted to develop more techniques that are culturally appropriate and clinically useful. Research has to be initiated to validate the identified concepts.

    Full Text Available Stories are powerful aids to reflection. Thus, the use of stories may be a pathway to enhanced reflective practice and clinical reasoning skills. The aim of this study was to evaluate whether and how digital storytelling can contribute to occupational therapy (OT students’ learning through reflections on experiences from placement education. A cohort of OT students (n = 57 participated in a 2-day workshop to create digital stories. Data were generated through a questionnaire with a response rate of 100% of students who completed the workshop (n = 34. Quantitative analysis methods were used to reveal a level of agreement in the questionnaire statements, and qualitative content analysis was performed for the open-ended questions. The results show that the students learned through reflection on placement experiences in the digital storytelling process as they emphasized reflection as a main outcome. They highlighted the importance of sharing thoughts and reflections with peers. The students confirmed that this happens through the creative process and the use of multimodality in poetic reflection, but they were less convinced by the use of the narrative approach as a dramatic structure. The students experienced reflection and sharing as important elements in the digital storytelling process. However, investigations are needed into the use of a narrative approach to enhance reflection with larger cohorts as well as more thematic analyses.

    In two experiments, we tested for a causal link between thought speed and risk taking. In Experiment 1, we manipulated thought speed by presenting neutral-content text at either a fast or a slow pace and having participants read the text aloud. In Experiment 2, we manipulated thought speed by presenting fast-, medium-, or slow-paced movie clips that contained similar content. Participants who were induced to think more quickly took more risks with actual money in Experiment 1 and reported greater intentions to engage in real-world risky behaviors, such as unprotected sex and illegal drug use, in Experiment 2. These experiments provide evidence that faster thinking induces greater risk taking.

    Satellite in the Jovian and Saturnian system exhibit differences in reflectivity between their 'leading' and 'trailing' surfaces which can affect the local vapor pressure. Since these differences are thought to be due to differences in the flux of bombarding magnetospheric ions, the influence of ion impact on the UV-visible reflectance of water ice surfaces (20-90 K) by keV ion bombardment was studied. An observed decrease in reflectance in the UV is attributed to rearrangement processes that affect the physical microstructure and surface 'roughness'. The ratio in reflectance of bombarded to freshly deposited films is compared to the ratio of the reflectance of the leading and trailing hemispheres for Europa and Ganymede.

    2017-11-01

    Current research into mind-wandering is beginning to acknowledge that this process is one of heterogeneity. Following on from previous findings highlighting the role of self-focus during mind wandering, the present study aimed to examine individual differences in rumination and self-reflection and the impact such styles of self-focus may have on mind-wandering experiences. Thirty-three participants were required to complete the Sustained Attention Response Task (SART), aimed at inducing mind-wandering episodes, whilst also probing the content of thought in terms of temporal focus. Self-report questionnaires were also administered after the SART to measure dispositional differences in style and beliefs regarding mind-wandering and assessments of individual differences in rumination and self-reflection. Those individuals with reflective self-focus showed a strong positive association with positive and constructive thoughts. Critically, ruminative self-focus was positively associated with a tendency for the mind to wander towards anguished fantasies, failures and aggression, but it was also positively associated with positive and constructive thoughts. Furthermore, while dispositional differences in self-focus showed no relationship with the temporal perspective of thoughts when probed during a cognitive task, performance on the task itself was related to whether participants were thinking about the past, present or future during that activity. Such findings are discussed in line with previous research, and provide a further step towards accounting for the heterogeneous nature of mind-wandering.

    Full Text Available The purpose of this paper is to highlight some difficulties of Neil Sinhababu’s Humean theory of agency, which depend on his radically reductivist approach, rather than to his Humean sympathies. The argument is that Sinhababu’s theory builds upon a critique of reflective agency which is based on equivocation and misunderstandings of the Kantian approach. Ultimately, the objection is that his reductivist view is unequipped to address the rclassical problems of rational deliberation and agential authority.

    The relationship between culture, language, and thought has long been one of the most important topics for those who wish to understand the nature of human cognition. This issue has been investigated for decades across a broad range of research disciplines. However, there has been scant communication across these different disciplines, a situation largely arising through differences in research interests and discrepancies in the definitions of key terms such as 'culture,' 'language,' and 'thought.' This article reviews recent trends in research on the relation between language, culture and thought to capture how cognitive psychology and cultural psychology have defined 'language' and 'culture,' and how this issue was addressed within each research discipline. We then review recent research conducted in interdisciplinary perspectives, which directly compared the roles of culture and language. Finally, we highlight the importance of considering the complex interplay between culture and language to provide a comprehensive picture of how language and culture affect thought.

    The aim of the present study was to evaluate the effects of gastric pH on the oral absorption of poorly water-soluble drugs using an in vitro system. A dissolution/permeation system (D/P system) equipped with a Caco-2 cell monolayer was used as the in vitro system to evaluate oral drug absorption, while a small vessel filled with simulated gastric fluid (SGF) was used to reflect the gastric dissolution phase. After applying drugs in their solid forms to SGF, SGF solution containing a 1/100 clinical dose of each drug was mixed with the apical solution of the D/P system, which was changed to fasted state-simulated intestinal fluid. Dissolved and permeated amounts on applied amount of drugs were then monitored for 2h. Similar experiments were performed using the same drugs, but without the gastric phase. Oral absorption with or without the gastric phase was predicted in humans based on the amount of the drug that permeated in the D/P system, assuming that the system without the gastric phase reflected human absorption with an elevated gastric pH. The dissolved amounts of basic drugs with poor water solubility, namely albendazole, dipyridamole, and ketoconazole, in the apical solution and their permeation across a Caco-2 cell monolayer were significantly enhanced when the gastric dissolution process was reflected due to the physicochemical properties of basic drugs. These amounts resulted in the prediction of higher oral absorption with normal gastric pH than with high gastric pH. On the other hand, when diclofenac sodium, the salt form of an acidic drug, was applied to the D/P system with the gastric phase, its dissolved and permeated amounts were significantly lower than those without the gastric phase. However, the oral absorption of diclofenac was predicted to be complete (96-98%) irrespective of gastric pH because the permeated amounts of diclofenac under both conditions were sufficiently high to achieve complete absorption. These estimations of the effects of

    A 3 kW single stage all-fiber Yb-doped single-mode fiber laser with bi-directional pumping configuration has been demonstrated. Our newly developed high-power LD modules are employed for a high available pump power of 4.9 kW. The length of the delivery fiber is 20 m which is long enough to be used in most of laser processing machines. An output power of 3 kW was achieved at a pump power of 4.23 kW. The slope efficiency was 70%. SRS was able to be suppressed at the same output power by increasing ratio of backward pump power. The SRS level was improved by 5dB when 57% backward pump ratio was adopted compared with the case of 50%. SRS was 35dB below the laser power at the output power of 3 kW even with a 20-m delivery fiber. The M-squared factor was 1.3. Single-mode beam quality was obtained. To evaluate practical utility of the 3 kW single-mode fiber laser, a Bead-on-Plate (BoP) test onto a pure copper plate was executed. The BoP test onto a copper plate was made without stopping or damaging the laser system. That indicates our high power single-mode fiber lasers can be used practically in processing of materials with high reflectivity and high thermal conductivity.

    This study tests the relation between eye-movements and thought processing. Subjects were given specific modality tasks (visual, gustatory, kinesthetic) and assessed on whether they responded with distinct eye-movements. Some subjects' eye-movements reflected ongoing thought processing. Instead of a universal pattern, as suggested by the neurolinguistic programming hypothesis, this study yielded subject-specific idiosyncratic eye-movements across all modalities. Included is a discussion of the neurolinguistic programming hypothesis regarding eye-movements and its implications for the eye-movement desensitization and reprocessing theory.

  2. Early maladaptive schemas and social anxiety in adolescents: the mediating role of anxious automatic thoughts.

    Cognitive models state that cognitions are organized hierarchically, so that the underlying schemas affect behavior via more automatic, superficial cognitive processes. This study aimed to demonstrate that early maladaptive schemas predict anxious automatic thoughts, and to show that such automatic thoughts act as mediators between schemas and prospective changes in social anxiety symptoms. The study also examined an alternative reverse model in which schemas acted as mediators between automatic thoughts and social anxiety. A total of 1052 adolescents (499 girls and 553 boys; M(age)=13.43; SD(age)=1.29) completed measures of early maladaptive schemas, socially anxious automatic thoughts, and social anxiety symptoms at Times 1, 2, and 3. The results revealed bidirectional longitudinal relationships among schemas and automatic thoughts that were consistent in content (e.g., the disconnection/rejection schemas and automatic thoughts of negative self-concept). Furthermore, the automatic thoughts of anticipatory negative evaluation by others at Time 2 mediated the relationship between the other-directedness schemas at Time 1 and social anxiety symptoms at Time 3. These findings are consistent with hierarchical cognitive models of social anxiety given that deeper schemas predict more surface-level thoughts. They also support that these more surface-level thoughts contribute to perpetuating schemas. Finally, results show that early maladaptive schemas of the other-directedness domain play a relevant role in the development and maintenance of social anxiety. Copyright © 2013 Elsevier Ltd.

  6. Thoughts in flight: automation use and pilots' task-related and task-unrelated thought.

    2014-05-01

    The objective was to examine the relationship between cockpit automation use and task-related and task-unrelated thought among airline pilots. Studies find that cockpit automation can sometimes relieve pilots of tedious control tasks and afford them more time to think ahead. Paradoxically, automation has also been shown to lead to lesser awareness. These results prompt the question of what pilots think about while using automation. A total of 18 airline pilots flew a Boeing 747-400 simulator while we recorded which of two levels of automation they used. As they worked, pilots were verbally probed about what they were thinking. Pilots were asked to categorize their thoughts as pertaining to (a) a specific task at hand, (b) higher-level flight-related thoughts (e.g.,planning ahead), or (c) thoughts unrelated to the flight. Pilots' performance was also measured. Pilots reported a smaller percentage of task-at-hand thoughts (27% vs. 50%) and a greater percentage of higher-level flight-related thoughts (56% vs. 29%) when using the higher level of automation. However, when all was going according to plan, using either level of automation, pilots also reported a higher percentage of task-unrelated thoughts (21%) than they did when in the midst of an unsuccessful performance (7%). Task-unrelated thoughts peaked at 25% when pilots were not interacting with the automation. Although cockpit automation may provide pilots with more time to think, it may encourage pilots to reinvest only some of this mental free time in thinking flight-related thoughts. This research informs the design of human-automation systems that more meaningfully engage the human operator.

  7. Neutron reflectivity

    2015-01-01

    Full Text Available The specular neutron reflectivity is a technique enabling the measurement of neutron scattering length density profile perpendicular to the plane of a surface or an interface, and thereby the profile of chemical composition. The characteristic sizes that are probed range from around 5 Å up 5000 Å. It is a scattering technique that averages information on the entire surface and it is therefore not possible to obtain information within the plane of the interface. The specific properties of neutrons (possibility of tuning the contrast by isotopic substitution, sensitivity to magnetism, negligible absorption, low energy of the incident neutrons makes it particularly interesting in the fields of soft matter, biophysics and magnetic thin films. This course is a basic introduction to the technique and does not address the magnetic reflectivity. It is composed of three parts describing respectively its principle and its formalism, the experimental aspects of the method (spectrometers, samples and two examples related to the materials for energy.

    This experiment found that the speed of thought affects mood. Thought speed was manipulated via participants' paced reading of statements designed to induce either an elated or a depressed mood. Participants not only experienced more positive mood in response to elation than in response to depression statements, but also experienced an independent increase in positive mood when they had been thinking fast rather than slow--for both elation and depression statements. This effect of thought speed extended beyond mood to other experiences often associated with mania (i.e., feelings of power, feelings of creativity, a heightened sense of energy, and inflated self-esteem or grandiosity).

    Subjects were shown a short film fragment. Following this, one group of subjects (n = 26) was instructed to suppress their thoughts about the film, while the other group (n = 24) received no instructions. After 5 hrs subjects returned to the laboratory and completed a questionnaire testing their memory about the film. Results showed that suppression subjects reported a higher frequency of thoughts about the film than control subjects. No evidence was obtained for Wegner, Quillian, and Houston's (1996; Journal of Personality and Social Psychology, 71, 680-691) claim that suppression has an undermining effect on memory for chronology. Possible causes for the differences between the results as obtained by Wegner et al., and those found in the present study are discussed. These causes may pertain to the experimental design, but also to differences in emotional impact of the stimulus material that was used in both studies.

    2012-01-01

    Full Text Available Poetry of Momcilo Nastasijevic gives us undoubted motive to talk about him as a consistent religious poet, a poet of orthodox religious inspiration. He approached towards words as sanctity, he endeavoured to measure each word, reach it, and clean it from accumulated dust of everyday’s blather. His attitude towards poetical locution, his personal law of poetical perfection, represents, brought up to the last consequences, principles of symbolist poetics. He thought of words as magic of sound and rhythm and examines all the effects we can get from it. To him, poetry was identical to crucial and the purest flickering of what he called human soul. The thought of our poet come down to essence of his poetry: who has understood his poems, can be sure that will understand Nastasijevic as a poet.

  11. Globalising the classical foundations of IPE thought

    2015-12-01

    Full Text Available Abstract Current efforts to teach and research the historical foundations of IPE thought in classical political economy in the 18th, 19th and early 20th centuries centre largely on European and American thinkers. If a more extensive 'global conversation' is to be fostered in the field today, the perspectives of thinkers in other regions need to be recognised, and brought into the mainstream of its intellectual history. As a first step towards 'globalising' the classical foundations of IPE thought, this article demonstrates some ways in which thinkers located beyond Europe and the United States engaged with and contributed to debates associated with the three well-known classical traditions on which current IPE scholarship often draws: economic liberalism, economic nationalism and Marxism. It also reveals the extensive nature of 'global conversations' about IPE issues in this earlier era.

  12. Ethical reflection and psychotherapy.

    Science.gov (United States)

    Vyskocilová, Jana; Prasko, Jan

    2013-01-01

    Theories of ethics and ethical reflection may be applied to both theory and practice in psychotherapy. There is a natural affinity between ethics and psychotherapy. Psychotherapy practice is concerned with human problems, dilemmas and emotions related to both one's own and other people's values. Ethics is also concerned with dilemmas in human thinking and with how these dilemmas reflect other individuals' values. Philosophical reflection itself is not a sufficient basis for the ethics of psychotherapy but it may aid in exploring attitudes related to psychotherapy, psychiatry and health care. PubMed, Web of Science and Scopus databases were searched for articles containing the keywords "psychotherapy", "ethics", "therapeutic relationship" and "supervision". The search was conducted by repeating the terms in various combinations without language or time restrictions. Also included were data from monographs cited in reviews. The resulting text is a review with conclusions concerning ethical aspects of psychotherapy. The ability to behave altruistically, sense for justice and reciprocity and mutual help are likely to be genetically determined as dispositions to be later developed by upbringing or to be formed or deformed by upbringing. Early experiences lead to formation of ethical attitudes which are internalized and then applied to both one's own and other people's behavior. Altruistic behavior has a strong impact on an individual's health and its acceptance may positively influence the pathophysiological mechanisms underlying numerous diseases. Ethical theory and reflection, however, may be applied to both theory and practice of psychotherapy in a conscious, targeted and thoughtful manner. In everyday practice, psychotherapists and organizations must necessarily deal with conscious conflicts between therapeutic possibilities, clients' wishes, their own as well as clients' ideas and the real world. Understanding one's own motives in therapy is one of the aims of a

  15. The geological thought process: A help in developing business instincts

    Energy Technology Data Exchange (ETDEWEB)

    1995-09-01

    Since the beginning of modern-day geology it has been understood that the present is the key to the past. However, when attempting to apply current geological models one discovers that there are no exact look-alikes. Thus, the geological discipline inherently accepts modifications, omissions, and relatively large margins of error compared with engineering. Geologists are comfortable in a world of non-unique solutions. Thus the experience in working with numerous geological settings is extremely critical in selecting the most reasonable geological interpretations, often by using a composite of specific models. One can not simply replace a dynamic geologist`s life-time of experiences and geologic instinct with simply a book-smart young upstart. Petroleum corporations accept geologic risk and manage it by drilling numerous wells in various geological provenances. Oil corporations have attempted to quantify and manage risk by using Monte Carlo simulations, thus invoking a formal discipline of risk. The acceptance of risk, results in an asset allocation approach to investing. Asset allocators attempt to reduce volatility and risk, inherently understanding that in any specific time interval anything can happen. Dollar cost averaging significantly reduces market risk over time, however it requires discipline and commitment. The single most important ingredient to a successful investing plan is to assign a reasonable holding period. Historically, a majority of the investment community demands instant gratification causing unneeded anxiety and failure. As in geology nothing can replace experience.

  17. The evolution of language and thought.

    Lieberman, Philip

    2016-06-20

    Language primarily evolved as a vocal medium that transmits the attributes of human culture and the necessities of daily communication. Human language has a long, complex evolutionary history. Language also serves as an instrument of thought since it has become evident that in the course of this process neural circuits that initially evolved to regulate motor control, motor responses to external events, and ultimately talking were recycled to serve tasks such as working memory, cognitive flexibility linguistic tasks such as comprehending distinctions in meaning conveyed by syntax. This precludes the human brain possessing an organ devoted exclusively to language, such as the Faculty of Language proposed by Chomsky (1972, 2012). In essence like Fodor's (1983) modular model, a restatement of archaic phrenological theories (Spurzheim, 1815). The subcortical basal ganglia can be traced back to early anurans. Although our knowledge of the neural circuits of the human brain is at a very early stage and incomplete, the findings of independent studies over the past 40 years, discussed here, have identified circuits linking the basal ganglia with various areas of prefrontal cortex, posterior cortical regions and other subcortical structures. These circuits are active in linguistic tasks such as lexical access, comprehending distinctions in meaning conferred by syntax and the range of higher cognitive tasks involving executive control and play a critical role in conferring cognitive flexibility. The cingulate cortex which appeared in Therapsids, transitional mammal-like reptiles who lived in age of the dinosaurs, most likely enhanced mother-infant interaction, contributing to success in the Darwinian (1859) "Struggle for Existence" - the survival of progeny. They continue to fill that role in present-day mammals as well as being involved in controlling laryngeal phonation during speech and directing attention (Newman & MacLean, 1983; Cummings, 1993".

    This thesis argues that Nietzsche’s thought takes two paths toward overcoming the nihilism of modern culture. It shows that affirmation is alternatively conceived as a revaluation of life and as a transfiguration of it, introducing an ambiguity at the heart of Nietzsche’s philosophy. Nietzsche’s aspiration to cultural regeneration prevents him from recognising the implications of affirmation as it is best conceived, as transfiguration, an aesthetic condition that cannot be imposed or designed...

    Portfolio learning enables students to collect evidence of their learning. Component tasks making up a portfolio can be devised that relate directly to intended learning outcomes. Reflective tasks can stimulate students to recognise their own learning needs. Assessment of portfolios using a rating scale relating to intended learning outcomes offers high content validity. This study evaluated a reflective portfolio used during a final-year attachment in general practice (family medicine). Students were asked to evaluate the portfolio (which used significant event analysis as a basis for reflection) as a learning tool. The validity and reliability of the portfolio as an assessment tool were also measured. 81 final-year medical students completed reflective significant event analyses as part of a portfolio created during a three-week attachment (clerkship) in general practice (family medicine). As well as two reflective significant event analyses each portfolio contained an audit and a health needs assessment. Portfolios were marked three times; by the student's GP teacher, the course organiser and by another teacher in the university department of general practice. Inter-rater reliability between pairs of markers was calculated. A questionnaire enabled the students' experience of portfolio learning to be determined. Benefits to learning from reflective learning were limited. Students said that they thought more about the patients they wrote up in significant event analyses but information as to the nature and effect of this was not forthcoming. Moderate inter-rater reliability (Spearman's Rho .65) was found between pairs of departmental raters dealing with larger numbers (20-60) of portfolios. Inter-rater reliability of marking involving GP tutors who only marked 1-3 portfolios was very low. Students rated highly their mentoring relationship with their GP teacher but found the portfolio tasks time-consuming. The inter-rater reliability observed in this study should

    2009-07-01

    Full Text Available This study follows two aims: one to review some late views on the relations among language, thought, and culture; and the other, to offer a new strategy, in a novel model, based on last achievements in the minimalist approach. Studying views and arguments, three dichotomies are discussed: 1 the views which confirm the relation between culture and language in opposition to the views that deny this; 2 distinguishing the symmetry-procedural view and the transforming views of language; and 3 distinction among the social-communicational, and the biological-genetic motivations of language. The hypothesis for the novel strategy is that considering what the minimalist program has offered, especially from 2000 onwards, it is possible that language affects thought, while coding the and that culture affects language (which is called ethno-grammar . This is in addition to the biological-genetic base. From this point of view, language’s main function is neither to provide communication, nor to express thought, but to connect cognitive and socio-cultural terminals together.

    To examine the significance of thought-action fusion (TAF) and thought suppression tendencies, the present study obtained pre- and post-treatment questionnaire data on these constructs in a sample of OCD patients (n=24) and non-OCD anxiety patients (n=20). Results indicate that TAF and suppression are correlated with severity of psychopathology. Yet, the associations between TAF and psychopathology are not typical for OCD, but do also occur in other anxiety disorders (e.g., panic disorder, post traumatic stress disorder, and social phobia). As well, mean scores on the TAF and thought suppression measures dropped significantly from pre- to post-treatment, indicating that TAF and thought suppression are susceptible to change during psychotherapy.

    Although an inflated sense of responsibility, thought-action fusion, and thought suppression are influential factors in cognitive models of obsessive-compulsive disorder (OCD), their impact on OCD has generally been demonstrated in samples from Western countries. The aim of the present study is to evaluate these cognitive factors in Turkish patients with OCD, other anxiety disorders, and community controls. Group comparisons showed that responsibility based on self-dangerousness and thought suppression significantly distinguished OCD patients from patients with other anxiety disorders and controls. Moreover, correlation and discriminant function analyses indicated that thought-action fusion in morality and likelihood was also associated with OCD symptoms. The present findings provide support for the international validity and specificity of cognitive factors and model for OCD.

    Life science has a need for detection methods that are label-free and real-time. In this paper, we have selected staphylococcal protein A (SPA) and swine immunoglobulin G (IgG), and monitor the bindings between SPA and swine IgG with different concentrations, as well as the dissociations of SPA-swine IgG complex in different pH values of phosphate buffer by oblique-incidence reflectivity difference (OIRD) in a label-free and real-time fashion. We obtain the ON and OFF reaction dynamic curves corresponding to the bindings and dissociations of SPA and swine IgG. Through our analysis of the experimental results, we have been able to obtain the damping coefficients and the dissociation time of SPA and swine IgG for different pH values of the phosphate buffer. The results prove that the OIRD technique is a competing method for monitoring the dynamic processes of biomolecule interaction and achieving the quantitative information of reaction kinetics.

    In casual conversations, words often lack segments. This study investigates whether listeners rely on their experience with reduced word pronunciation variants during the processing of single segment reduction. We tested three groups of listeners in a lexical decision experiment with French words produced either with or without word-medial schwa (e.g., /ʀvy/ and /ʀvy/ for revue). Participants also rated the relative frequencies of the two pronunciation variants of the words. If the recognition accuracy and reaction times (RTs) for a given listener group correlate best with the frequencies of occurrence holding for that given listener group, recognition is influenced by listeners' exposure to these variants. Native listeners' relative frequency ratings correlated well with their accuracy scores and RTs. Dutch advanced learners' accuracy scores and RTs were best predicted by their own ratings. In contrast, the accuracy and RTs from Dutch beginner learners of French could not be predicted by any relative frequency rating; the rating task was probably too difficult for them. The participant groups showed behaviour reflecting their difference in experience with the pronunciation variants. Our results strongly suggest that listeners store the frequencies of occurrence of pronunciation variants, and consequently the variants themselves.

    Full Text Available Background and context: I have been working as a practice developer in the Australian healthcare system for more than 10 years. For the last seven of those I was a lead facilitator for a practice development programme that is being implemented across a large statewide health service. The programme’s purpose is to create person-centred care environments that enable patient and staff empowerment. My role was in a small team that supported facilitators predominantly at local health district and state levels. The intent was to phase out the team over time as capacity increased and local teams gained the required skills and knowledge to continue implementing the programme. During the two-year final transition phase, a strategic plan was implemented to guide the development of systems and capacity that would support the programme once the team had exited. A decision was made to shorten the phasing-out period and during this transition period I found myself facing an unknown and unpredictable future, for the first time in my career promoting something other than my clinical nursing skills. As I transitioned into an independent facilitator role I wanted to consolidate my expertise as a facilitator, to gain further learning in specific areas and to achieve recognition of the facilitation skill set I had honed over time, and which has now become my way of working. Given that my experience was limited to the healthcare context, diverse though it is, I pondered which of my skills would stand me in good stead to enable groups and organisations as an independent professional facilitator and what additional skills I’d need. I was encouraged to become a certified professional facilitator by colleagues who were using process facilitation and person-centredness more broadly. This paper reflects my experience of the preparation, assessment and accreditation process, the feedback I received from my international assessors and how these are influencing my

  9. Some thoughts on power: International context

    2014-01-01

    Full Text Available This is a polemical essay that enters into broad dialogue with the contemporary literature concerning the dynamic of power. It refers to the appropriate material and results from the research of different theories. It proposes the constitutive position of the power in the international situation. In contrast to some current theories, we emphasize the importance of the politicoeconomical approach, denoting that only the methodology based on the logics of political economy can explain the dynamics of power in the international context. The main thread of this essay is that the international constellation is not a neutral environment, but a framework that is deeply determined by the power-relations. The central idea is that these relations should be explicated by the complex relationships between freedom and order. We analyze the interaction between the politics and economy as the constitutive feature of the structure of international context. This essay is divided into three sections. First, we are treating the meaning of order in an international context, in respect to the political-economic aspects of late capitalism. The notion of this order has a great importance in the economic reflections. The dynamic of the interconnectedness of global capitalism is examined considering the systematic aspects of power. After that we are analyzing different, and selected, aspects of the international sphere including: the spatiality of the world order, that is, the spatial aspects of the international dynamics in the context of globalization, the convergence or divergence between the capitalist and territorial logic, the “legaleconomic nexus” in international “chain”, the processes of the modification of the forms of competition within recent globalization, and the political-economic conflicts in relation to the regime of economic measurement. Starting with these considerations we explain the current debates on “demondialization”, or the

    This article traces the history of the concept of dignity in Western thought, arguing that it became a formal Catholic theological concept only in the late nineteenth century. Three uses of the word are distinguished: intrinsic, attributed, and inflorescent dignity, of which, it is argued, the intrinsic conception is foundational. The moral norms associated with respect for intrinsic dignity are discussed briefly. The scriptural and theological bases for adopting the concept of dignity as a Christian idea are elucidated. The article concludes by discussing the relevance of this concept of dignity to the spiritual and ethical care of the dying.

  12. Principles of shape from specular reflection

    KAUST Repository

    Balzer, Jonathan

    2010-12-01

    The reconstruction of (partially) specular object by means of deflectometric methods is a challenging task. It has a long and fairly branched history within the metrology and machine vision communities. We are not aware of any scientific publication surveying the state of the art in a unifying manner and thus stimulating further research. This contribution is intended to close this gap, bringing together prominent ideas from both fields. In avoidance of unnecessary technicality, we lay out the basic theory, including all known forward models of the reflection process. The corresponding inverse problem is ill-posed, so that special emphasis is put on the question of regularization. We embed some novel results on the uniqueness problem and the effectiveness of regularization approaches. Also an overview of numerical methods related to Shape from Specular Reflection is given. For the sake of completeness, we share some thoughts on the construction of an actual measurement system and discuss a practical example. © 2010 Elsevier Ltd. All rights reserved.

    Manufacturing the solid dosage form of an orally administered drug requires lubrication to enhance manufacturability, ensuring that critical quality attributes such as disintegration and dissolution of the drug product are maintained during manufacture. Here, to evaluate lubrication performance during manufacture, we used terahertz attenuated total reflection (THz-ATR) spectroscopy to detect differences in the physical characteristics of the lubricated powder. We applied a simple formulation prepared by blending granulated lactose as filler with magnesium stearate as lubricant. A flat tablet was prepared using the lubricated powder to acquire sharp THz-ATR absorption peaks of the samples. First, we investigated the effects of lubricant concentration and compression pressure on preparation of the tablet and then determined the effect of the pressure applied to samples in contact with the ATR prism on sample absorption amplitude. We focused on the differences in the magnitudes of spectra at the lactose-specific frequency. Second, we conducted the dynamic lubrication process using a 120-L mixer to investigate differences in the magnitudes of absorption corresponding to the lactose-specific frequency during lubrication. In both studies, enriching the lubricated powder with a higher concentration of magnesium stearate or prolonging blending time correlated with higher magnitudes of spectra at the lactose-specific frequency. Further, in the dynamic lubrication study, the wettability and disintegration time of the tablets were compared with the absorption spectra amplitudes at the lactose-specific frequency. We conclude that THz-ATR spectroscopy is useful for detecting differences in densities caused by a change in the physical properties of lactose during lubrication.

  15. A Marked Poisson Process Driven Latent Shape Model for 3D Segmentation of Reflectance Confocal Microscopy Image Stacks of Human Skin

    Segmenting objects of interest from 3D datasets is a common problem encountered in biological data. Small field of view and intrinsic biological variability combined with optically subtle changes of intensity, resolution and low contrast in images make the task of segmentation difficult, especially for microscopy of unstained living or freshly excised thick tissues. Incorporating shape information in addition to the appearance of the object of interest can often help improve segmentation performance. However, shapes of objects in tissue can be highly variable and design of a flexible shape model that encompasses these variations is challenging. To address such complex segmentation problems, we propose a unified probabilistic framework that can incorporate the uncertainty associated with complex shapes, variable appearance and unknown locations. The driving application which inspired the development of this framework is a biologically important segmentation problem: the task of automatically detecting and segmenting the dermal-epidermal junction (DEJ) in 3D reflectance confocal microscopy (RCM) images of human skin. RCM imaging allows noninvasive observation of cellular, nuclear and morphological detail. The DEJ is an important morphological feature as it is where disorder, disease and cancer usually start. Detecting the DEJ is challenging because it is a 2D surface in a 3D volume which has strong but highly variable number of irregularly spaced and variably shaped “peaks and valleys”. In addition, RCM imaging resolution, contrast and intensity vary with depth. Thus a prior model needs to incorporate the intrinsic structure while allowing variability in essentially all its parameters. We propose a model which can incorporate objects of interest with complex shapes and variable appearance in an unsupervised setting by utilizing domain knowledge to build appropriate priors of the model. Our novel strategy to model this structure combines a spatial Poisson process

  16. The point of no return: A fundamental limit on the ability to control thought and action.

    Science.gov (United States)

    Logan, Gordon D

    2015-01-01

    Bartlett (1958. Thinking. New York: Basic Books) described the point of no return as a point of irrevocable commitment to action, which was preceded by a period of gradually increasing commitment. As such, the point of no return reflects a fundamental limit on the ability to control thought and action. I review the literature on the point of no return, taking three perspectives. First, I consider the point of no return from the perspective of the controlled act, as a locus in the architecture and anatomy of the underlying processes. I review experiments from the stop-signal paradigm that suggest that the point of no return is located late in the response system. Then I consider the point of no return from the perspective of the act of control that tries to change the controlled act before it becomes irrevocable. From this perspective, the point of no return is a point in time that provides enough "lead time" for the act of control to take effect. I review experiments that measure the response time to the stop signal as the lead time required for response inhibition in the stop-signal paradigm. Finally, I consider the point of no return in hierarchically controlled tasks, in which there may be many points of no return at different levels of the hierarchy. I review experiments on skilled typing that suggest different points of no return for the commands that determine what is typed and the countermands that inhibit typing, with increasing commitment to action the lower the level in the hierarchy. I end by considering the point of no return in perception and thought as well as action.

    The current study examined the effects of a psychoeducational intervention designed to target thought-action fusion (TAF) on TAF, thought suppression, and responsibility cognitions. 139 undergraduate students (25 male; 114 female) who were relatively high in TAF with respect to their peers served as participants. Immediately following intervention, individuals who had received psychoeducation regarding TAF reported significantly lower morality TAF scores than individuals who had received psychoeducation regarding thoughts in general and individuals in the control group. At the two-week follow-up assessment, the likelihood TAF scores of those who had received psychoeducation regarding TAF were significantly lower than those of the control group. In addition, the group that received psychoeducation regarding TAF was the only group that did not experience a significant increase in thought suppression from baseline to post-intervention, and was also the only group to experience an increase in both frequency of and belief in low-responsibility thoughts from baseline to follow-up. Implications are discussed. (c) 2010 Elsevier Ltd. All rights reserved.

    The aim of this paper is to present Finnish employees' opinions on continuing work until retirement pension and after the age of 63, and to find out if physical workload is related to these opinions. Altogether 39% of men and 40% of women had never had thoughts of early retirement, and 59% claimed (both men and women) that they would consider working beyond the age of 63. Own health (20%); financial gain such as salary and better pension (19%); meaningful, interesting and challenging work (15%); flexible working hours or part-time work (13%); lighter work load (13%); good work community (8%); and good work environment (6%) were stated as factors affecting the decision to continue working after the age of 63. Employees whose work involved low physical workload had less thoughts of early retirement and had considered continuing work after the age of 63 more often than those whose work involved high physical loads. Own health in particular was stated as a reason to consider continuing work by employees whose work was physically demanding.

    Full Text Available Love is a basic subject of Islamic mysticism. It is apparently the hallmark of Eynolghozat's thought as well. Hence, Mystics pronounce him as "Sheikh-al-Asheghin", "Sultan-al-oshshagh", and so on. Eynalghozat considers love as a common faith between God, human beings, and the whole universe by which enmity changes to friendship. He also considers love as a perfect leader who guides the lovers through the way ending to the eminent God. In his opinion, Love which can never be spoken of except by symbolic language is of three main types Great Love, e, middle love, and lower love. Like other mystics figurative (platonic love id of considerable importance for him. However, the first and second types of love -mentioned above- are much more prevalent in his works. In this article, the writer tries to supply a brief definition of love in Eynolghozat's opinion, as well as a comparison of his thoughts with his master that is, Ahmad Ghazali.

    The Nominalists of the XIV century, precursors of modern science, thought that science's object was not the general, vague and indeterminate but the particular, which is real and can be known directly. About the middle of the XVII Century the bases of the modern science became established thanks to a revolution fomented essentially by Galileo, Bacon and Descartes. During the XVIII Century, parallel to the development of the great current of English Empiricism, a movement of scientific renewal also arose in continental Europe following the discipline of the Dutch Physicians and of Boerhaave. In the XIX Century, Claude Bernard dominated the scientific medicine but his rigorous determinism impeded him from taking into account the immense and unforeseeable field of the random. Nowadays, we approach natural science and medicine, from particular groups of facts; that is, from the responses of Nature to specific questions, but not from the general laws. Furthermore, in recent epistemology, the concept that experimental data are not pure facts, but rather, facts interpreted within a hermeneutical context has been established. Finally a general tendency to retrieve philosophical questions concerning the understanding of essence and existence can frequently be seen in scientific inquiry. In the light of the evolution of medical thought, it is possible to establish the position of scientific medicine within the movement of ideas dominating in our time.

    This article looks at the theme of order in Thomas De Quincey’s Suspiria de Profundis (1845). Although chaos is easily noticeable in De Quincey’s digressional style, order is also a recurring motif in the narrative of this mature work. Indeed, for the Protestant and Romantic author plagued by suffering, chaos and order are the starting points for broader reflections. De Quincey discovers that chaos in the outer and inner worlds is but apparent, and that deciphering these worlds enables him to...

    Models of cognitive processing in anxiety disorders state that socially anxious children display several distorted cognitive processes that maintain their anxiety. The present study investigated the role of social threat thoughts and social skills perception in relation to childhood trait and state social anxiety. In total, 141 children varying in their levels of social anxiety performed a short speech task in front of a camera and filled out self-reports about their trait social anxiety, state anxiety, social skills perception and social threat thoughts. Results showed that social threat thoughts mediated the relationship between trait social anxiety and state anxiety after the speech task, even when controlling for baseline state anxiety. Furthermore, we found that children with higher trait anxiety and more social threat thoughts had a lower perception of their social skills, but did not display a social skills deficit. These results provide evidence for the applicability of the cognitive social anxiety model to children.

    Full Text Available The need to appreciate the interconnectedness of all life on Earth has never been more important than it is today, as our own species, mostly through ignorance, threatens to unravel the rich biological tapestry of which we are a part, and upon which we ultimately depend. Art, and especially imagery, can play a crucial role in reestablishing the profound and vital link between ourselves as individuals and the natural world. Recognizing this, conservationists are making ever more use of illustration in education campaigns worldwide on behalf of endangered wildlife and ecosystems. In this article I have tried to articulate my own feelings about nature, to trace the path that led me to work in this specialized area of art, and to relate some of the lessons I have learned applying illustration to conservation.

    2016-01-01

    Dysphoria is associated with persistence of attention on mood-congruent information. Longer time attending to mood-congruent information for dysphoric individuals (DIs) detracts from goal-relevant information processing and should reduce working memory (WM) capacity. Study 1 showed that DIs and non-DIs have similar WM capacities. Study 2 embedded depressive information into a WM task. Compared to non-DIs, DIs showed significantly reduced WM capacity for goal-relevant information in this task. Study 3 replicated results from Studies 1 and 2, and further showed that DIs had a significantly greater association between processing speed and recall on the depressively modified WM task compared to non-DIs. The presence of inter-task depressive information leads to DI-related decreased WM capacity. Results suggest dysphoria-related WM capacity deficits when depressive thoughts are present. WM capacity deficits in the presence of depressive thoughts are a plausible mechanism to explain day-to-day memory and concentration difficulties associated with depressed mood.

    2009-11-01

    Full Text Available This paper provides an insight into an e-learning design approach that has been used by the author in a wide range of contexts in Higher Education as part of an ongoing enquiry into transforming online teaching and learning within sustainable 'real' courses. A key driver has been the need to engage learners in Higher Education in moving from consumers to producers of knowledge and to engage in communities of practice through the use of online tools for learning. These developments use an analytic framework to support thoughtful e-learning design and insights into the way his framework has been applied are presented through a number of case studies. This work is shaping Web2.0 technologies to match a learning rather than a social agenda by casting them in particular learning activities within specific contexts for particular learning purposes.Keywords: e-learning, activity theory

With two EEG electrodes placed on the scalp of the user, EEG signals are amplified and digitised directly using a ProComp+ encoder and transferred to the host computer through the RS232 interface. Using a real-time multilayer neural network, the actual classification for the control of a powered wheelchair has a very fast response. It can detect changes in the user's thought pattern in 1 second. Using only two EEG electrodes at positions O(1) and C(4) the system can classify three mental commands (forward, left and right) with an accuracy of more than 79 %

    2004-06-01

    The cognitive bias of "Thought Action Fusion" (TAF) has received significant research attention in the past decade. The review addresses the assessment of TAF, its place in cognitive theories of obsessional difficulties, and the evidence demonstrating that TAF is relevant to disorders beyond Obsessive Compulsive Disorder (OCD). Data on the components of TAF, its extension to positive outcomes and its role in the aetiology, maintenance and treatment of OCD are reviewed. It is concluded that the moral form of TAF is less robust than the likelihood form and that scales may be best used as a starting point in identifying beliefs and conducting experimental investigations. It is also suggested that the scales be amended to include harm avoidance, which would also increase their clinical utility.

    The goal of this study was to investigate whether or not a brief educational intervention delivered prior to engaging in an anxiety-provoking task (writing a sentence about hoping that a friend/relative was in a car accident) would be effective in offsetting anxiety in college students with a strong propensity to endorse statements of thought action fusion (TAF). As hypothesized, individuals receiving the educational intervention were less anxious than a placebo intervention control group at post task; they were also less likely to endorse statements of TAF after receiving the educational intervention. Also, those who chose to neutralize after writing the sentence (regardless of experimental group) were more likely to report feeling guiltier, more immoral and a greater sense of responsibility about writing the sentence prior to neutralizing than those who did not subsequently neutralize. These results are discussed in relation to the cognitive theory of obsessive-compulsive disorder and implications for prevention programs.

In Experiment 1, imagining a specific scenario in which meaning is preserved beyond death reduced DTA relative to a standard mortality salience prime; moreover, these effects were not due to changes in self-esteem. In Experiment 2, imagining a meaningful life when mortality is salient elicited greater DTA, whereas imagining meaning in death elicited less DTA. Imbuing death with meaning attenuates DTA, whereas meaning in life increases DTA. © 2017 The British Psychological Society.

    Full Text Available For more than 14 centuries, history has proved that Islamic teachings come with a variety of thoughts, social cultural backgrounds, periods through which the development and the dynamics evolved. The primary mission of mankind as the khalifah fil ardh (the caliph of the earth, is to practice the Islamic teachings (Shariah in accordance with the provisions of the primary source of Islam itself, i.e. the Qur’an and Hadith. At least, a long history of Islam as a religion of revelation suggests that the existence of Islamic teachings can grow and develop in every corner of the world, with a variety of spreading patterns that give the nuances and the mosaics in the development of the religion the present day.

    In 2012, 22 days of beam time will be allocated for LHC MDs. In this paper, after recalling the 2011 LHC MD experience, the MD rrequests for 2012 are reviewed. Three primary MD themes for 2012 can be identified: 1)pushing performance in 2012, 2)preparing for 2014/15, and 3)towards maximum luminosity. Example topics include emittance growth in collision or enhanced satellites for theme 1), 25 ns operation for 2), and ATS optics for 3). Structures lists of MD requests and topics for each theme as well as some initial thoughts on the MD priorities are presented. For certain topics, "start-of-fill MDs" are proposed in order to most efficiently use of the available beam time.

  19. RETHINKING THE ANIMATE, RE-ANIMATING THOUGHT

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

  1. It Could Have Been True: How Counterfactual Thoughts Reduce Condemnation of Falsehoods and Increase Political Polarization.

    Science.gov (United States)

    Effron, Daniel A

    2018-05-01

    This research demonstrates how counterfactual thoughts can lead people to excuse others for telling falsehoods. When a falsehood aligned with participants' political preferences, reflecting on how it could have been true led them to judge it as less unethical to tell, which in turn led them to judge a politician who told it as having a more moral character and deserving less punishment. When a falsehood did not align with political preferences, this effect was significantly smaller and less reliable, in part because people doubted the plausibility of the relevant counterfactual thoughts. These results emerged independently in three studies (two preregistered; total N = 2,783) and in meta- and Bayesian analyses, regardless of whether participants considered the same counterfactuals or generated their own. The results reveal how counterfactual thoughts can amplify partisan differences in judgments of alleged dishonesty. I discuss implications for theories of counterfactual thinking and motivated moral reasoning.

  2. Stand-alone polarization-modulation infrared reflection absorption spectroscopy instrument optimized for the study of catalytic processes at elevated pressures

    This paper describes the design and construction of a compact, "user-friendly" polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS) instrument at the Center for Functional Nanomaterials (CFN) of Brookhaven National Laboratory, which allows studying surfaces at pressures ranging from ultra-high vacuum to 100 Torr. Surface infrared spectroscopy is ideally suited for studying these processes as the vibrational frequencies of the IR chromophores are sensitive to the nature of the bonding environment on the surface. Relying on the surface selection rules, by modulating the polarization of incident light, it is possible to separate the contributions from the isotropic gas or solution phase, from the surface bound species. A spectral frequency range between 1000 cm-1 and 4000 cm-1 can be acquired. While typical spectra with a good signal to noise ratio can be obtained at elevated pressures of gases in ˜2 min at 4 cm-1 resolution, we have also acquired higher resolution spectra at 0.25 cm-1 with longer acquisition times. By way of verification, CO uptake on a heavily oxidized Ru(0001) sample was studied. As part of this test study, the presence of CO adsorbed on Ru bridge sites was confirmed, in agreement with previous ambient pressure X ray photoelectron spectroscopy studies. In terms of instrument performance, it was also determined that the gas phase contribution from CO could be completely removed even up to pressures close to 100 Torr. A second test study demonstrated the use of the technique for studying morphological properties of a spin coated polymer on a conductive surface. Note that this is a novel application of this technique. In this experiment, the polarization of incident light was modulated manually (vs. through a photoelastic modulator). It was demonstrated, in good agreement with the literature, that the polymer chains preferentially lie parallel with the surface. This PM-IRRAS system is small, modular, and easily

    The evolution history of Central Asian Orogen Belt (CAOB) is still the main tectonic problems in northeastern Asia. The Siberia Craton (NC), North China Craton (NCC) and several blocks collided, and the resulting tectonic collage formed as the Paleo-Asian Ocean disappeared. Concerning the northern margin of North China Craton, many different geological questions remain unanswered, such as: the intracontinental orogenic process in the Yanshan orogen and the nature and location of the suture between the southern NC and the northern NCC. In Dec 2009, a 400 km long seismic refraction and wide-angle reflection profile was completed jointly by Institute of Geology, CAGS and University of Oklahoma. The survey line extended from the west end of the Yanshan orogen, across a granitoid belt to the Solonker suture zone. The recording of seismic waves from 8 explosions (500~1500 kg each) was conducted in four deployments of 300 Reftek125 (Texan) seismic recorders, with an average spacing of 1 km. For the calculations, we used the Rayinvr, Vmed and Zplot programs for ray tracing, model modification and phase picking. The initial result show that: 1)the depth of low velocity sediment cover ranges from 0.6 to 2.7 km (velocity: 2.8~5.6 km/s); 2)the depth of basement is 5.6~10 km (the depth of basement under the granitoid belt deepens to 10 km and velocity increases to 6.2 km/s); 3)the upper crust extends to a depth of 15.5~21 km and has the P-wave velocities between 5.6 and 6.4 km/s; 4)the thickness of the lower crust ranges from 22~28 km(velocity: 6.4~6.9 km/s); and 5)the depth of Moho varies from 39.5 km under the granitoid belt to 49 km under the Yanshan orogen. Based on these results, we can preliminarily deduce that: 1) the concave depression of the Moho observed represents the root of the Yanshan orogen, and it may prove that the orogen is dominated by thick-skinned tectonics; 2) the shape of velocity variations under the granitoid belt is suggestive of a magma conduit.

    Full Text Available This article looks at the theme of order in Thomas De Quincey’s Suspiria de Profundis (1845. Although chaos is easily noticeable in De Quincey’s digressional style, order is also a recurring motif in the narrative of this mature work. Indeed, for the Protestant and Romantic author plagued by suffering, chaos and order are the starting points for broader reflections. De Quincey discovers that chaos in the outer and inner worlds is but apparent, and that deciphering these worlds enables him to see a unifying or organizing force beneath contraries and paradoxes. As a consequence, in his hermeneutics based on the scandal of suffering, De Quincey introduces the notion of obliqueness operating through the masks behind which God acts, thus retracing the very paths taken by God and disclosing his own theology.

    1978-06-01

    The effects of mood upon imaginal thought were explored with a highly trained undergraduate female hypnotic subject. She was hypnotically programmed to experience free-floating anxiety or pleasure in varying degrees just before the exposure of combinations of three Blacky Pictures, and to produce dreamlike imagery in response to the Blacky stimuli while under sway of the mood. Data from 98 dream trials, separated by amnesia, indicated that the affective states clearly influenced imaginal processes. Blind ratings by a psychoanalyst showed anxiety moods to be more closely associated with primary-process features characteristic of nocturnal dreams, whereas pleasure had a relatively higher incidence of daydreamlike ratings. Empirical analysis of themes yielded significant relationships of anxiety to physical injury to the self and verbal aggression toward others; pleasure was associated with circular movements and overt sex themes.

  6. Medial prefrontal cortex subserves diverse forms of self-reflection.

    2011-01-01

    The ability to think about oneself--to self--reflect--is one of the defining features of the human mind. Recent research has suggested that this ability may be subserved by a particular brain region: the medial prefrontal cortex (MPFC). However, although humans can contemplate a variety of different aspects of themselves, including their stable personality traits, current feelings, and physical attributes, no research has directly examined the extent to which these different forms of self-reflection are subserved by common mechanisms. To address this question, participants were scanned using functional magnetic resonance imaging (fMRI) while making judgments about their own personality traits, current mental states, and physical attributes as well as those of another person. Whereas some brain regions responded preferentially during only one form of self-reflection, a robust region of MPFC was engaged preferentially during self-reflection across all three types of judgment. These results suggest that--although dissociable--diverse forms of self-referential thought draw on a shared cognitive process subserved by MPFC.

    The aim of this paper is to explore the diversity and progress in psychoanalysis and psychotherapy post-Sigmund Freud from the perspective of Western art. Since 1900 the shift from one-person psychology to the more contemporary two-person psychology is reflected in the creativity of artists, particularly in their depiction of the mother-infant relationship. An alternative perspective in understanding the evolution of Man's nature can be drawn from a discourse between art, history and psychoanalytic thought. Using art as evidence that reflects concurrent changes in psychoanalytic thought is a stimulating way to engage trainee psychiatrists and psychiatrists in their exploration of human nature.

    Full Text Available Objective – To explore student thought on both reflection and reflective writing as a process, and to analyze the writing by the application of clearly defined and identifiable outcomes.Design – Mixed method approach consisting of a qualitative analysis of 116 written reflections from master’s level students as well as a quantitative statistical analysis.Setting –The University of Sheffield masters-level librarianship program’s course INF6005, “Management for LIS.”Subjects – Of the 31 students registered the course during the 2007-2008 academic year, 22 (71%, allowed their reflections to be used for the purposes of research. Of these, 7 students identified themselves as male, and 15 were female. All students included were over 21 years of age and had previous library experience, with varying degrees of management experience in supervisory roles. Not all supervisory experience was gathered within the library domain.Methods –A total of 116 reflective journal entries were submitted by the participating students during the eight month period from October 2008 to May 2009. In order to identify themes, qualitative analysis was applied to the reflective writing responses. Descriptive statistics were also applied to test the hypothesis, illustrate the relationships between reflective writing and outcomes, and locate identifiable outcomes.Main Results – Practising reflection demonstrated benefits for individuals groups both in and outside of the workplace. On the whole, individuals gained the most from reflection and saw it in the most positive light when it was practised as a daily activity. Quantitatively, when students began to master the practice of reflection, they demonstrated an increase in their ability to learn and an overall improvement of self-development and critical thinking skills, and gained a defined awareness of personal mental function. When decision making became easier, students understood they had begun to master

  10. Hannah Arendt, evil and the eradication of thought.

    2012-10-01

    Evil deeds may be committed intentionally or out of madness, but it is those who follow orders that present us with the most complex moral, philosophical and psychological questions. In writing about the banality of evil, Hannah Arendt argues that "in granting pardon, it is the person and not the crime that is forgiven; in rootless evil there is no person left whom one could ever forgive." Arendt postulates that "being a person" necessarily entails the acts of memory and thought. This paper explores Arendt's ideas on memory and thought and how these processes can become subverted in the service of a higher order. Clinical material illustrates Whitmer's idea of dissociation as an "impairment of subjectivity" as distinct from Freud's view of dissociation as a form of repression. This shift in theoretical perspective sheds new light on our understanding of the totalitarian state of mind, i.e. of the mind of a "nobody", and the conditions within which evil is committed.

  12. No Evidence for a Food-Related Attention Bias after Thought Suppression

    2008-01-01

    Full Text Available The aim of this study was to investigate whether food-related thought suppression results in an attention bias for food cues. Fifty-nine female students took part in the experiment. All completed a modified exogenous cueing task containing pictures of foods and toys with a similar valence (presentation duration: 250 ms and 1050 ms. Half of the participants were instructed to suppress thoughts about food and the other half was given control instructions, prior to completing the exogenous cueing task. No evidence was found for an enhanced cue validity effect for food cues after food-related thought suppression. Hence, the preliminary results do not provide support for the hypothesis that thought suppression is sufficient to yield an attention bias. Since the study was the first to employ an exogenous cueing task to study the attentional processing of food cues, replication is warranted.

    Endo, Hiroko; Yukawa, Shintaro

    2013-12-01

    Endo and Yukawa (2012) investigated the process of maintaining anger and demonstrated that a sense of unintegration of thoughts maintained anger by promoting recurrent thinking and avoidance behavior. Our present study examined how personality characteristics and situational factors affected the process of maintaining anger. Undergraduates (N=713) wrote about an anger episode, and completed questionnaires assessing their sense of unintegration of thoughts, recurrent thinking, avoidance behaviors, and maintaining anger. The questionnaires also assessed personality characteristics such as difficulty in identifying feelings, and situational factors such as the need for maintaining relationships, anger arousability, and meaning-making for the anger episode. The results of covariance structure analysis indicated that difficulties in identifying feelings and anger arousability contributed to maintaining anger by increasing the sense of unintegration of thoughts just after the episode. However, the need for maintaining relationships directly reduced the sense of unintegration of thoughts just after the episode, and indirectly decreased the present sense of unintegration of thoughts by meaning-making. Moreover, although recurrent thinking promoted the current sense of unintegration of thoughts, it also provided meaning.

  14. Some thoughts on psychoanalysis and ethics.

    Science.gov (United States)

    Szpilka, Jaime

    2002-10-01

    The author attempts to establish a framework for understanding the contribution of psychoanalysis to ethics through examining the work of certain philosophers, especially Kant. After reviewing the development of Freudian thought and going beyond the 'psychoanalysis and/or psychiatry?' question, he asserts that the space of the psychoanalytical cure revolves around an ethical problem. Thus, the limits of analysis should be determined by the subject's capacity for developing a structure of belief in the unconscious, with the concomitant capacity to go beyond equivocation in respect of an ethical conflict that underlies all cases where psychical suffering is manifested. Indeed, only human beings are called upon to deal with an ethical paradox-equally a logical one-which could be stated thus: there is Good in Evil and Evil in Good. This ethical paradox is the consequence of human subjection to the constituent laws of the Oedipus complex, which distances the human being, in his/her dealings with Evil and with Good, from any naturalist stance. In respect of the cure, then, we must take into account that Evil does not proceed from any particular drive-based characteristic, but is rather the expression of specific subjection to an unconscious Other, towards which it directs its affects. Finally, the author proposes a principle that emerges from the preceding discussion: let us not impute to or place in the Other our own subjective splitting or pain at existing.

The author assumes that the analysis of the folklore stories might allow defining the archetypes, which in a certain manner affect the contemporary political thought in Russia. The author demonstrates the way in which the national cultural archetypes relate to the common cultural ones (Greek myths, on the one hand, and, on the other hand, contain their specific national modification. Thus, the Hero Archetype in Russian epos appears to be nationally marked (its Russianness is particularly stressed as well as the image of an enemy, filling in the Shadow Archetype. Russian ‘bogatyr’ is traditionally on a state service and remains faithful to his grand duke, notwithstanding the injustice of the latter. The characters of fairy tales wage “preventive wars” in which they become the winners. The contemporary Russian political discourse inherits, to a certain extent, the value as well as the worldview aspects of the Russian epos.

    Full Text Available Scientific normativity of law conceived as a character inherent in legal science as a sui generis. Jurisprudence basically studies the law, something that initially emerged from the dogmatic belief in philosophy. Dogmatism refuse to alter beliefs one iota. The teachings of dogmatic philosophy stem from the teachings of Plato and reflected in the legal enforceability. Dogmatism in the law is reflected in the Corpus Juris Civilis. Along with the development of post Era Scholastic philosophical thinking, the philosophy synthesizes thought between dogmatic thinking and skeptic has appeared in the Age of Enlightenment. This idea is reflected in Transcendental Idealist philosophy thought of Immanuel Kant. The core idea is that real human beings are given the ability to understand based on empirical experience and actually also able to gain an understanding of the human being that is the essence of symptoms. Transcendental Idealist, thus dynamic, moving to look for values that are useful for life. Transcendental Idealist thought then be adopted Kelsen in the teaching of normativity in legal positivism. Normativity in the teachings of Hans Kelsen’s legal positivism derived from the integration of empirical positivism and idealistic empiricism.

    With the discovery of the Aristotelian works on "natural philosophy" the philosophical discourse expands its subject of study to the physical and material dimension of men's nature. This philosophical tendency would also influence the reflections on musical topics. This paper shows how the physiological and physical view of the human being had influenced the theory of music. From a terminological and a conceptual perspective Pietro de Abano moves away from the Boethian authority. Comparing the musical theory of Pietro de Abano with the traditional "musica theorica" it becomes evident that there is no opposition between sensitiveness and intellect.

    Lyons, Kristen E; Zelazo, Philip David

    2011-01-01

    While an abundance of research has investigated the development of the automatic and controlled processes through which individuals control their thoughts, emotions, and actions, less research has emphasized the role of the self in self-regulation. This chapter synthesizes four literatures that have examined the mechanisms through which the individual acts in a managerial role, evaluating the current status of the system and initiating regulatory actions as necessary. Taken together, these literatures (on executive function, error monitoring, metacognition, and uncertainty monitoring) suggest that self-reflection plays a critical role in self-regulation, and that developmental improvements in self-reflection (via increasing levels of conscious awareness and enhanced calibration of monitoring systems) may serve as driving forces underlying developmental improvement (and temperamental individual differences) in children's ability to control their thoughts and actions.

    Hendricks-Thomas, J; Patterson, E

    1995-09-01

    A critical analysis of nurse education programmes has revealed an overt and covert curriculum; the overt being the one underpinned by values which espouse humanism and critical thought; the covert being the one which reflects the patriarchal system and is directed by a means-end rationality. In response to this dilemma the 'curriculum revolution' mandate for change, which occurred in the latter half of the last decade, called for nurse educators to unveil, understand and criticize the assumptions and values which guided their practice, so that they, and consequently their students, could be more responsive to the needs of society, value subjective experience, acknowledge theoretical pluralism, and share an egalitarian relationship. This paper explores the formation of a 'critical collective' of nurse academics who came together believing that, 'if you always do what you've always done, you'll always get what you've already got'. The major concern of this collective was to facilitate change within their work environment, through the development of strategies, so that the ideas of the 'revolution' were not lost to the mere rhetoric of curriculum documents.

  1. Thought insertion as a self-disturbance: An integration of predictive coding and phenomenological approaches

    Directory of Open Access Journals (Sweden)

    Philipp Sterzer

    2016-10-01

    Full Text Available Current theories in the framework of hierarchical predictive coding propose that positive symptoms of schizophrenia, such as delusions and hallucinations, arise from an alteration in Bayesian inference, the term inference referring to a process by which learned predictions are used to infer probable causes of sensory data. However, for one particularly striking and frequent symptom of schizophrenia, thought insertion, no plausible account has been proposed in terms of the predictive-coding framework. Here we propose that thought insertion is due to an altered experience of thoughts as coming from nowhere, as is already indicated by the early 20th century phenomenological accounts by the early Heidelberg School of psychiatry. These accounts identified thought insertion as one of the self-disturbances (from German: Ichstörungen of schizophrenia and used mescaline as a model-psychosis in healthy individuals to explore the possible mechanisms. The early Heidelberg School (Gruhle, Mayer-Gross, Beringer first named and defined the self-disturbances, and proposed that thought insertion involves a disruption of the inner connectedness of thoughts and experiences, and a becoming sensory of those thoughts experienced as inserted. This account offers a novel way to integrate the phenomenology of thought insertion with the predictive coding framework. We argue that the altered experience of thoughts may be caused by a reduced precision of context-dependent predictions, relative to sensory precision. According to the principles of Bayesian inference, this reduced precision leads to increased prediction-error signals evoked by the neural activity that encodes thoughts. Thus, in analogy with the prediction-error related aberrant salience of external events that has been proposed previously, internal events such as thoughts (including volitions, emotions and memories can also be associated with increased prediction-error signaling and are thus imbued with

  2. Medical humanities in nursing: thought provoking?

    Robb, A J; Murray, R

    1992-10-01

    Medical humanities is an innovative way of learning. Discussing literary texts of nursing practice has been used to help students analyse attitudes, values and ethics; it has also been used to help practitioners review and reflect on their own experience and philosophy of nursing. In nursing education, it has been used to explore difficult issues in a safe environment. The value of this approach in nursing education and practice is that it can encourage reflection, promote self-awareness and stimulate debate on difficult issues: for example, death and dying, power and institutionalization (of patients and staff) and pain. This paper gives a detailed worked example of how a literary text can be used in this way, the aim being to provide a resource which readers can then use with a group of students or colleagues. Finally, the authors explore the question of where medical humanities might have a place in the curriculum: as a lecture/tutorial in a course (e.g. Ethics), as a module in the curriculum, as a method of teaching nursing subjects (e.g. communication skills), as a discussion group (outside the curriculum), as a study guide, using literary texts alongside nursing text books. Any of these strategies can be a powerful vehicle for preserving the 'human factor' in both nursing education and continuing professional development.

    Quéré, Louis

    2010-01-01

    For George Herbert Mead, thinking amounts to holding an "inner conversation of gestures ". Such a conception does not seem especially original at first glance. What makes it truly original is the "social-behavioral" approach of which it is a part, and, particularly, two ideas. The first is that the conversation in question is a conversation of gestures or attitudes, and the second, that thought and reflexive intelligence arise from the internalization of an external process supported by the social mechanism of communication: that of conduct organization. It imports then to understand what distinguishes such ideas from those of the founder of behavioral psychology, John B. Watson, for whom thinking amounts to nothing other than subvocal speech.

    A thought analysis on the self-organization theories of dissipative MHD plasma is presented to lead to three groups of theories that lead to the same relaxed state of ∇ x B = λB, in order to find an essential physical picture embedded in the self-organization phenomena due to nonlinear and dissipative processes. The self-organized relaxed state due to the dissipation by the Ohm loss is shown to be formulated generally as the state such that yields the minimum dissipation rate of global auto-and/or cross-correlations between two quantities in j, B, and A for their own instantaneous values of the global correlations.

Four factors contributing to the changed viewpoint are: First, deepwater reservoirs have proved to have excellent productive capacity, distribution, and continuity when compared to correlative-age shelf deltaic sands. Second, improved technologies and lower perceived risks have lowered the cost of floating production systems (FPSs). Third, projects now get on-line quicker. Fourth, a collection of other important factors are: Reduced geologic risk and associated high success rates for deepwater GOM wells due primarily to improved seismic imaging and processing tools (3D, AVO, etc.); absence of any political risk in the deepwater GOM (common overseas, and very significant in some international areas); and positive impact of deepwater federal royalty relief. This article uses hypothetical reserve distributions and price forecasts to illustrate indicative economics of deepwater prospects. Economics of Shell Oil Co.'s three deepwater projects are also discussed

    The use of journaling or journal writing in clinical education is one of the strategies used to develop critical thinking. Reflective journal writing, as it is commonly known, can nurture many qualities of a critical thinker and promote thoughtful nursing practice. Using a quasi-experimental design in this study, reflective journaling was introduced to a sample of first year Bridging Course student nurses at a Private Nursing Education Institution, to assess its effectiveness in reflective learning. The study design enabled comparisons between two groups: one group of students assigned to do journaling (experimental group) and another group of students (control group) who did not journal. The students in the experimental group were given a period of eight weeks to journal their clinical experiences. At the end of this period, both groups were given an exercise, based on a clinical situation, to analyse reflectively and a comparison made on their performance. Descriptive statistics were used to analyse data and Fisher's Exact Test was used to determine the significance of differences observed within and between groups. The results showed that students in the experimental group performed better in exploring alternatives of action (p < 0.10) and formulating responses in similar future situations (p < 0.05) during the process of reflection. There was no significant difference between the groups' scores with regard to their ability to describe the clinical experience, to explore their related feelings, to evaluate the experience and to interpret/create meaning for themselves. Recommendations are made for continued student support and guidance during clinical education if reflection is considered to enhance reflective, thoughtful nursing practice.

    According to unconscious thought theory (UTT), unconscious thought is more adept at complex decision-making than is conscious thought. Related research has mainly focused on the complexity of decision-making tasks as determined by the amount of information provided. However, the complexity of the rules generating this information also influences decision making. Therefore, we examined whether unconscious thought facilitates the detection of rules during a complex decision-making task. Participants were presented with two types of letter strings. One type matched a grammatical rule, while the other did not. Participants were then divided into three groups according to whether they made decisions using conscious thought, unconscious thought, or immediate decision. The results demonstrated that the unconscious thought group was more accurate in identifying letter strings that conformed to the grammatical rule than were the conscious thought and immediate decision groups. Moreover, performance of the conscious thought and immediate decision groups was similar. We conclude that unconscious thought facilitates the detection of complex rules, which is consistent with UTT.

    Full Text Available Medicine and literature have always been connected over the ages. William Shakespeare (1564-1616 is no exception. There are plenty of references to medicine and diseases in the works of Shakespeare. The knowledge which Shakespeare has of medical conditions is much more than is expected of a common man. This is attributed to his association with practitioners of his time and reading of contemporary texts in medicine. Also his son in law Dr. John Hall who married Susanna, Shakespeare's eldest daughter would have contributed substantially to the knowledge of medicine in Shakespeare's compositions. Surgery at the Elizabethan times was well known and is reflected to a large extent in his plays.

  11. Some wicked thoughts on nursing leadership.

    Nursing is everywhere in healthcare and at all levels, and is among other things numerically dominant. Yet it arguably plays a less prominent role in charting the future course of the system than it should. As in any complex system, power matters in health, and the history of healthcare and gender relations explains a good deal of why nursing's influence has not rivaled that of medicine. But society has progressed immensely in the last century and nursing has both contributed to and benefited from these broader social trajectories. If the profession is to expand its leadership role in healthcare, it will have to reflect on its internal politics, its culture of representation and decision-making, and how to translate its diversity into a coherent change agenda. Perhaps above all it must champion and focus on the public interest to avoid being defined as just another interest group.

    According to dual processing theory there are two types, or modes, of thinking: system 1, which involves intuitive and nonreflective thinking, and system 2, which is more deliberate and requires conscious effort and thought. The Cognitive Reflection Test (CRT) is a widely used and robust three item instrument that measures the tendency to override…

  13. Faulty Suppression of Irrelevant Material in Patients with Thought Disorder Linked to Attenuated Frontotemporal Activation

    Full Text Available Formal thought disorder is a feature schizophrenia that manifests as disorganized, incoherent speech, and is associated with a poor clinical outcome. The neurocognitive basis of this symptom is unclear but it is thought to involve an impairment in semantic processing classically described as a loosening of meaningful associations. Using a paradigm derived from the n400 event-related, potential, we examined the extent to which regional activation during semantic processing is altered in schizophrenic patients with formal thought disorder. Ten healthy control and 18 schizophrenic participants (9 with and 9 without formal thought disorder performed a semantic decision sentence task during an event-related functional magnetic resonance imaging experiment. We employed analysis of variance to estimate the main effects of semantic congruency and groups on activation and specific effects of formal thought disorder were addressed using post-hoc comparisons. We found that the frontotemporal network, normally engaged by a semantic decision task, was underactivated in schizophrenia, particularly in patients with FTD. This network is implicated in the inhibition of automatically primed stimuli and impairment of its function interferes with language processing and contributes to the production of incoherent speech.

    Full Text Available Abstract Background Suicidal thought is a risk factor and a stage in the suicidal process from planning to attempting and dying by suicide. To date, studies on suicidal thought in the general population, especially in Asian communities, have been limited. Method The WHO SUPRE-MISS (the multisite intervention study on suicidal behaviours community survey questionnaire was filled in for 2,280 randomly selected residents of the DongDa district of Hanoi, Vietnam by means of face-to-face interviews. This multi-factor questionnaire includes such variables as sociodemographic information, suicidal thought and history of suicide attempts, physical health, alcohol consumption and medication. Results Prevalence rates for life time suicidal thoughts, suicide plans and suicide attempts were 8.9%, 1.1% and 0.4% respectively. Suicidal thoughts are associated with multiple characteristics, such as female gender, single/widowed/separated/divorced marital status, low income, lifestyle (use of alcohol, sedatives and pain relief medication, but not with low education or employment status. Having no religion and being a Buddhist appear to be protective factors for suicidal thought. The ratio of suicidal thoughts, suicide plans and suicide attempts on a lifetime basis is 22.3:2.8:1. Conclusion In Vietnam, as in Western and other Asian countries, suicidal thoughts are associated with similar negative psychosocial risk factors, lifestyle and emotional problems, which implies that suicide preventive measure developed elsewhere can be adjusted to Vietnamese condition. Understanding the unique and common risks in a culture may assist in prediction and control.

  15. Nonconscious processes and health.

    Health behavior theories focus on the role of conscious, reflective factors (e.g., behavioral intentions, risk perceptions) in predicting and changing behavior. Dual-process models, on the other hand, propose that health actions are guided not only by a conscious, reflective, rule-based system but also by a nonconscious, impulsive, associative system. This article argues that research on health decisions, actions, and outcomes will be enriched by greater consideration of nonconscious processes. A narrative review is presented that delineates research on implicit cognition, implicit affect, and implicit motivation. In each case, we describe the key ideas, how they have been taken up in health psychology, and the possibilities for behavior change interventions, before outlining directions that might profitably be taken in future research. Correlational research on implicit cognitive and affective processes (attentional bias and implicit attitudes) has recently been supplemented by intervention studies using implementation intentions and practice-based training that show promising effects. Studies of implicit motivation (health goal priming) have also observed encouraging findings. There is considerable scope for further investigations of implicit affect control, unconscious thought, and the automatization of striving for health goals. Research on nonconscious processes holds significant potential that can and should be developed by health psychologists. Consideration of impulsive as well as reflective processes will engender new targets for intervention and should ultimately enhance the effectiveness of behavior change efforts.

    Full Text Available It is hard to provide an unequivocal answer to the question of whether or not thought suppression is effective. Two thought suppression paradigms - the “white bear” paradigm and the think/no-think paradigm - give mixed results. Generally, “white bear” experiments indicate that thought suppression is counterproductive, while experiments in the think/no-think paradigm suggest that it is possible to effectively suppress a thought. There are also alternative methods used to study thought suppression, for instance the directed forgetting paradigm or the Stroop task. In the article, I describe the research methods used to explore thought suppression efficacy. I focus on the “white bear” and the think/no-think paradigms and discuss theories proposed to explain the results obtained. I also consider the internal and external validity of the methods used.

  18. Reflections on the fundamentals of Geoethics

    Tinti, Stefano; Armigliato, Alberto

    2017-04-01

    Geoethics is a relatively new entry in the world of geosciences and in the last years has found a receptive forum in scientific congresses and publications, since there is an increasing recognition that it raises important and crucial issues. In spite of this growth of interest, there is a lack of foundational concepts defining its role and scope. This work presents thoughts ad reflections on the foundation of Geoethics, and proposes answers to basic issues such as: Has it to be viewed as an independent science, at the border between geosciences and ethics? Is it one of the many branches of geosciences, or rather a branch of ethics? Is it a social science? What are the main themes of Geoethics? There is a need for a systematization of Geoethics, avoiding that different experts speak different languages or use the same words with different meanings. To answer the above questions, it is useful to consider the development of Bioethics, that is a discipline that had its foundation well before Geoethics and that at the beginning of its history was affected by analogous problems of disordered growth. While waiting for a definition of the status of Geoethics, here it is stressed, that Geoethics has to mark a cultural progress in the way geoscientists see their role and their responsibilities, at a scale from local to global, to ensure that today's and future societies are built and grow with the knowledge and awareness of opportunities and constraints provided by the basic processes of Nature.
