In this article we deal with Glivenko type theorems for intuitionistic modal logics over Prior's MIPC. We examine the problems which appear in proving Glivenko type theorems when passing from the intuitionistic propositional logic Intto MIPC. As a result we obtain two different versions of Glivenko's theorem for logics over MIPC. Since MIPCcan be thought of as a one-variable fragment of the intuitionistic predicate logic Q-Int, one of the versions of Glivenko's theorem for logics over MIPCis closely related to that for intermediate predicate logics obtained by Umezawa [27] and Gabbay [15]. Another one is rather surprising.  相似文献

IntroductionThe use of EMDR – Eye Movement Desensitization and Reprocessing – being innovative in the area of chronic pain. If his efficiency as show in the specific litterature, the way its work it is really different than usual therapy.ObjectiveThe main objective of this work is to compare the speech of patients during the use of EMDR vs. supportive therapy in a supported unit of chronic pain to the hospital.MethodsForty-five patients divided into three groups received EMDR therapy (standard protocol), EMDR therapy (pain protocol) as well as supportive therapy. All interviews were transcribed and analyzed using the software Alceste.ResultsThe results show that the semantic classes differ between the three forms of therapy, as well as passive or active posture of the patient during the therapy.ConclusionThese results give us an additional insights into what happens in fine in different types of therapy.  相似文献

Molecular dynamics simulations have been conducted to study implantation of boron with a low kinetic energy (E k in the range 5 eV) into the silicon surface. The bombarded surface has a realistic stepped structure and the geometry of the step edge is taken from the theory of Chadi (1987, Phys. Rev. Lett., 59, 1691). It is found that reflection is the more common event. However subsurface implants and adatom formations are also observed. The effect of the step morphology is important and different trajectories are observed if the ions hit steps of different shapes.  相似文献

Objective: While high levels of dietary restraint do not appear to reflect actual caloric restraint, it has been found to be a risk factor for a wide array of maladaptive eating patterns. These findings raise the question what, if not caloric restriction, dietary restraint entails. We propose that the very finding that restrained eaters do not eat less than they intend to do can provide an answer. Based on this disparity between the intention to restrain oneself and actual behaviour, we therefore hypothesised that high levels of restraint are associated with eating-related guilt.

Method: Three studies (N?=?148) using unobtrusive measures of food intake; different restraint scales; and different measures of guilt tested whether restraint is related to eating-related guilt.

Results: Results indicated that restraint was not associated with food intake, but instead was associated with increased levels of guilt after eating. Guilt was explicitly related to food intake. Moreover, the observed guilt could not be attributed to a general increase in negative affect.

Conclusion: The results of these studies suggest that restraint is not an indicator of actual restricted food intake, but rather a reflection concerns about food and eating manifested in eating-related guilt.  相似文献

Background: There are many professional psychotherapists, but no psychotherapy profession. The psychotherapists’ professions vary between countries, the most frequent being psychiatry and clinical psychology.

Aim: As these professions have different basic training and also may be impacted differently by other factors, we wanted to study potential differences as to perceived influences on their development as psychotherapists across career level, theoretical orientation, and gender.

Methods: More than 2500 Norwegian and German psychiatrists and psychologists reported data on their professional development in the DPCCQ/2000, a lengthy multi-part survey instrument developed within the ‘Collaborative Research Network’ of the Society for Psychotherapy Research. The four groups were compared for differences, and a series of multiple regression analyses were conducted to examine the impact of profession on a variety of aspects of therapist experiences.

Results: Although a few therapist experiences (e.g. teaching, treating patients, institutional conditions) had a significantly different impact between the two professions, as a main effect, they only accounted for less than 1% or the variance.

Conclusion: Profession seems to have little influence on perceived development as a psychotherapist, and it is reasonable to conclude that other therapist qualities, often personal qualities, are more important for therapeutic processes and outcomes.  相似文献

ObjectivesWe used a cognitive load perspective to investigate the effects of levels of learner expertise and different forms of segmentation in learning from animated soccer scenes.MethodExpert and novice players (N = 48) completed a recall reconstruction-test and rated their invested mental effort after studying a continuous animation, a macro-step and a micro-step segmented animation.ResultsFindings demonstrated an expertise reversal effect for segmentation. It positively affected learning outcomes of novices but not experts (even though they still invested less mental effort and repeated the animation less often in the two segmented conditions). Additionally, novices benefited more from micro-step segmentation than from macro-step segmentation, while experts performed at the same level with both forms of segmentation.ConclusionsStudy results suggested that adapting instructional animation formats to players with different levels of expertise should be a crucial part of successful training.  相似文献

In this paper, we compare several cut-free sequent systems for propositional intuitionistic logic Intwith respect to polynomial simulations. Such calculi can be divided into two classes, namely single-succedent calculi (like Gentzen's LJ) and multi-succedent calculi. We show that the latter allow for more compact proofs than the former. Moreover, for some classes of formulae, the same is true if proofs in single-succedent calculi are directed acyclic graphs (dags) instead of trees. Additionally, we investigate the effect of weakening rules on the structure and length of dag proofs.The second topic of this paper is the effect of different embeddings from Int to S4. We select two different embeddings from the literature and show that translated (propositional) intuitionistic formulae have sometimes exponentially shorter minimal proofs in a cut-free Gentzen system for S4than the original formula in a cut-free single-succedent Gentzen system for Int. Moreover, the length and the structure of proofs of translated formulae crucially depend on the chosen embedding.  相似文献

Abstract

Psychology is approached as a storytelling discipline Various narrative devices used in many formal psychological tales are identified. George Kelly's approach to telling is claimed to be very different, implying a different attitude to knowing and a different approach to knowledge. Following from this a proposal is made concerning the kind of psychology Kelly was, perhaps, reaching toward  相似文献

Statement of problemA variety of conceptions of qualitative research exist. This leads to a situation in which there are competing claims as to what counts as good-quality work. These competing claims revolve around the issue of criteria and how they are used to pass judgment on qualitative research. Those involved in sport and exercise sciences need to reflect on this issue with a view to generating further dialogue and a greater understanding of difference within the research community.MethodTwo ideal types of researcher, one a criteriologist the other a relativist, are constructed to illustrate how each might judge qualitative studies of different kinds.ResultsA comparison of the ways in which the criteriologist and the relativist draw on different assumptions to judge qualitative studies illustrates the constraining nature of the former and the expansive possibilities of the latter.ConclusionsCriteria should be viewed as lists of characterizing traits that are open to reinterpretation as times, conditions, and purposes change. Researchers need to adopt the role of connoisseur in order to pass judgment on different kinds of study in a fair and ethical manner.  相似文献

ObjectivesIt has been theorized that happiness is derived from three major, unique sets of life experience: pleasure, engagement, and meaning. The present study examined the mental processes by which individuals combined five information cues (relatedness, autonomy, competence, mental vitality and physical vitality) when judging the degree of happiness felt by a trail runner during a run.Design/methodThe participants (104 adult male athletes; Mage = 32.70; SD = 10.86) rated pleasure, engagement, and meaning in 32 scenarios built from combinations of these cues.ResultsThe results of multivariate and univariate analyses of variance indicated that all five cues had a positive effect on judgments of pleasure, engagement, and meaning. The participants used three different information integration rules, depending on the pathway to happiness being probed.ConclusionsThe information integration and the integration rules highlighted the different contributions of pleasure, engagement, and meaning in cognitive building of happiness.  相似文献

IntroductionTeachers tend to develop negative expectations and behaviours towards students coming from low socioeconomic backgrounds.ObjectiveThe objective of this study was to test the influence of teacher political orientation, as well as their attachment to power and universalism values, on their predictions of academic success towards students from different socioeconomic backgrounds.MethodEighty-eight high school teachers (Mage = 38.04 years; 44.3% men) responded to a questionnaire of political ideology and values, as well as to a questionnaire evaluating their prediction of success towards male high school students from different socioeconomic backgrounds.ResultsTeachers predicted a better academic success for students coming from a high socioeconomic background. Despite relatively small effect size, political ideology, as well as attachment to power and universalism values, predicted the bias of judgment.ConclusionTaking into consideration teachers’ ideology and values would deepen understanding of processes underlying expectations development.  相似文献

IntroductionResearch has shown that lay people, and even psychologists, may have distorted knowledge about memory functioning. May different study programs in psychology influence their ideas?Objective(s)The study was aimed at evaluating psychology students’ and psychology professors’ knowledge about memory and factors potentially affecting the accuracy of episodic memory reports in clinical and legal contexts.MethodA questionnaire was administered to introductory and advanced students of psychology enrolled at different curricula – experimental psychology and clinical psychology with a psychoanalytical orientation – and to professors teaching the courses in the same curricula.ResultsResults showed that advanced students and professors in experimental psychology have higher general knowledge of factors influencing memory performance than their peers, including memory issues of particular relevance to clinical psychology; no difference between the curricula was found for the introductory students.ConclusionThe results are discussed in terms of the risks that the lack of knowledge on memory functioning of the psychologists with a psychodynamic orientation may have in producing wrong reports in forensic contexts.  相似文献

ObjectivesSport developmental models contend that participating in different sports promotes expertise development, implying positive skill transfer between sports. This study conceptualizes and examines how specific and general transfer occur and interact between sports in the short- (skill transfer) and long-term (learning transfer). Specific transfer is predicated on the perception and utilisation of specifying information in a transfer task, while general transfer relies on non-specifying, "general" information. Furthermore, the study examined how certain conditions (affordance similarity, perceptual-motor exploration and expertise) promote the transfer process.DesignSystematic literature review.MethodsAn electronic search was performed on SPORTDiscuss, Pubmed/MEDLINE, and Scopus. Studies were included if participants performed a transfer task in a sport different to the sport they learned a skill in.ResultsA total of 17 studies of low-to-moderate quality were included. Most studies showed specificity of transfer between sports with overlapping affordances and generality of transfer between sports with no overlapping affordances (for a given skill). Only 2 studies examined how perceptual-motor exploration supported specific transfer, and 2 examined transfer for (subsequent) learning with contrasting results. Six studies indicated an expertise effect, showing higher transfer in skilled vs less-skilled athletes.ConclusionsThis review provides a conceptualization of specificity and generality of transfer, and initial evidence on how transfer emerges between sports in the short-term. It provides little information on the general-specific interaction in the short-term, and does not provide any insights on how transfer emerges in mid- and long-term. As such, no inference regarding sport developmental models can be made. The low-to-moderate quality of the studies requires caution in interpreting these findings. We encourage future research to investigate general and specific transfer longitudinally, recruiting populations with different expertise levels to further advance our current understanding.  相似文献

ObjectiveThe aim of this study was to examine the influence of a defender on the performance of a motor skill from an invasion sport.DesignHighly skilled basketball players performed different variations of basketball shots using a randomised test schedule.MethodParticipants completed a total of 30 test trials comprising 6 trials of 5 different shot types in both defended and undefended conditions.ResultsThe presence of a defender led to significant changes in several behavioral measures including faster shot execution times, longer jump times, and an increase in the amount of time that the ball spent in the air as it travelled to the basket after being released from the shooter's hand. These behavioral changes were accompanied by an overall decline in shooting accuracy of over 20%. Defended shots also tended to elicit greater amounts of movement variability which, when interpreted in conjunction with the other findings, suggests that participants were attempting to adapt their movements to accommodate for the changing demands of the performance environment. Comparisons across different shot types revealed that the influence of the defender was generally context and task dependent.ConclusionsThe results have important implications for representative task design, and highlight how the manipulation of key information sources can have a marked effect upon behavioral responses.  相似文献

ObjectivesThe purpose of the present study was to explore possible multiple motives for participation in different adventure sports.DesignQualitative design, specifically an inductive-deductive approach informed by reversal theory, was used to analyze participation motivation data.MethodData was collected using the Scanlan Collaborative Interview Method (SCIM; Scanlan, Russell, Wilson, & Scanlan, 2003). Participants were very experienced adventure sport participants involved in riversurfing, mountain biking, kayaking, mountain climbing and hang gliding.ResultsThe results indicated that the participants' motivation was multifaceted. While some participants shared common motives, these were often described in different orders of importance by different participants. The range of motives for adventure sport participation found included: goal achievement, risk taking, social motivation, escape from boredom, pushing personal boundaries and overcoming fear, as well as connecting with the natural environment, and pleasurable kinaesthetic bodily sensations from moving in water or air.ConclusionsThe authors argue for a continuation of a recent trend to provide a more comprehensive picture of the complexities of human motivation for participation in adventure sports which go beyond excitement- or thrill-seeking behaviour.  相似文献

IntroductionThe Object Spatial Imagery and Verbal Questionnaire (OSIVQ) measures individual differences in Visual-Verbal cognitive style and distinguishes between spatial and object visual imagery.ObjectiveThe aim of this study was to evaluate the psychometric properties of a French version of the OSIVQ.MethodSeven hundred fifty-two participants completed the French OSIVQ and 144 of them also completed a paper-and-pencil assessment to evaluate spatial imagery, object imagery and verbal abilities.ResultsPrincipal component analyses of the OSIVQ showed good internal construct validity. Results also revealed pronounced individual differences and a significant gender effect. Confirmatory factorial analyses gave support to a three-dimensional model of cognitive style. Furthermore, correlations were observed across the different dimensions of the questionnaire and specific paper-and-pencil tasks.ConclusionOur results highlight the good psychometric properties of the French version of the OSIVQ.  相似文献

Background/ObjectiveThe aims of this study were to explore the heterogeneity of resources, as described by the Conservation of Resources (COR) theory, in a sample of cancer and psoriatic patients and to investigate whether heterogeneity within resources explains differences in Posttraumatic Growth (PTG) level within each of these clinical samples and in a non-clinical control group.MethodThe sample consisted of 925 participants, including 190 adults with a clinical diagnosis of gastrointestinal cancer, 355 adults with a medical diagnosis of psoriasis, and 380 non-clinical (without any chronic illnesses) adults, all of whom had suffered various adverse and traumatic events. The participants completed a COR evaluation questionnaire and a posttraumatic growth inventory.ResultsA latent profile analysis revealed four different classes of psoriatic patients and five classes of cancer patients, all with different resources levels. Clinical subsamples differed substantially with PTG levels compared to healthy controls.ConclusionsOur study did not find a sole pattern of PTG that fit all the individuals, even for those who experienced the same type of traumatic event. Psychological counseling, in chronic illness particularly, should focus on the heterogenetic profiles of patients with different psychosocial characteristics.  相似文献

Background and Objectives: The present research examined the underlying factor structure of posttraumatic stress disorder (PTSD) as conceptualized in the recently published fifth edition of the Diagnostic and statistical manual of mental disorders (DSM-5). Design: Participants were 258 trauma-exposed Iraq/Afghanistan war veterans. Methods: A self-report measure of PTSD symptoms was administered to all participants and confirmatory factor analysis (CFA) was used to compare several different models of PTSD. Results: CFA revealed that the best-fitting model was a six-factor model in which symptoms loaded onto the factors of intrusion, avoidance, negative affect, anhedonia, dysphoric arousal, and anxious arousal. Conclusions: These findings have important implications for ongoing conceptualization of PTSD and suggest that additional modifications to the diagnostic criteria for PTSD may still be warranted to more accurately reflect the underlying structure of PTSD symptoms.  相似文献

ObjectiveTo determine the profile of high-performing college soccer teams through the use of exploratory hierarchical linear modeling (HLM) based on a socio-cognitive approach.DesignA correlational design was employed in this study. The sample consisted of 340 college soccer players of both genders (178 female and 162 male), representing 17 different teams (8 female and 9 male) ranked in the top-32 of the National Association of Intercollegiate Athletics (NAIA).MethodsNumerous demographic and soccer-related variables represented level-1 in the HLM model. Group Environment Questionnaire and Team Assessment Diagnostic Measure were entered as level-2 variables, representing cohesion and team mental models, respectively. Perceived performance potential (PPP) served as the dependent variable. Objective performance scores were correlated with PPP, attesting a moderate to high-level of criterion related validity (r = .78).ResultsThe final model suggested that: (a) International athletes perceive their performance lower than others, (b) different field positions share different covariance coefficients with PPP, and (c) perception of social cohesion from a group, rather than individual, standpoint is positively associated with perceptions of team performance.ConclusionsHigh performing teams have clearly defined task-related and team-related goals. Accordingly, social rather than task related factors may represent a competitive edge, further energizing the interactions and performance of top-ranked teams. International athletes perceive team performance lower than locals, perhaps due to differences in preferred game-style and acculturation experiences. Players from different field positions (i.e., goalkeepers, defensive, and offensive players) relate differently to team performance in college soccer.  相似文献

Introduction. This study examines differences in students’ perceived value of three artmaking modalities (poetry, comics, masks) and whether the resulting creative projects offer similar or different insights into medical students’ professional identity formation. Methods. Mixed-methods design using a student survey, student narrative comments and qualitative analysis of students’ original work. Results. Poetry and comics stimulated insight, but masks were more enjoyable and stress-reducing. All three art modalities expressed tension between personal and professional identities. Discussion. Regardless of type of artmaking, students express concern about encroachments of training on personal identity but hoped that personal and professional selves could be integrated.
