Some work has been carried out in the past on statistically deriving priorities in Analytic Hierarchy Process (AHP). In AHP, the aggregated worths of the alternatives, when compared with respect to several criteria, are estimated in a hierarchical comparisons model introduced by Saaty. In this setup, statistical models are used for Saaty's method of scaling in paired comparisons experiments in any level of the hierarchy. At the end, the final priority weights of the alternatives and related inferences are developed with appropriate statistical methods. Existing statistical methods in the literature assume independence of the entries of the paired comparison matrix. However, these entries are highly dependent among themselves. In this article, we propose a statistical method that allows for the dependence among the entries of the pairwise comparisons matrix. The proposed method is then illustrated with a numerical example.

Language production has been found to be lateralized in the left hemisphere (LH) for 95% of right-handed people and about 75% of left-handers. The prevalence of atypical right hemispheric (RH) or bilateral lateralization for reading and colateralization of production with word reading laterality has never been tested in a large sample. In this study, we scanned 57 left-handers who had previously been identified as being clearly left (N = 30), bilateral (N = 7) or clearly right (N = 20) dominant for speech on the basis of fMRI activity in the inferior frontal gyrus (pars opercularis/pars triangularis) during a silent word generation task. They were asked to perform a lexical decision task, in which words were contrasted against checkerboards, to test the lateralization of reading in the ventral occipitotemporal region. Lateralization indices for both tasks correlated significantly (r = 0.59). The majority of subjects showed most activity during lexical decision in the hemisphere that was identified as their word production dominant hemisphere. However, more than half of the sample (N = 31) had bilateral activity for the lexical decision task without a clear dominant role for either the LH or RH, and three showed a crossed frontotemporal lateralization pattern. These findings have consequences for neurobiological models relating phonological and orthographic processes, and for lateralization measurements for clinical purposes. 相似文献

This article offers a limited defense of metaphysical “infinitism,” the view that there are, or might be, infinite chains of ontological dependence. According to a widespread presupposition, there must be an ultimate ground of being—most likely, a plurality of fundamental atoms. Contrary to this view, this article shows that metaphysical infinitism is internally coherent. In particular, a parallel with the debate concerning infinitism about epistemic justification is suggested, and an “emergence model” of being is put forward. According to the emergence model, the being of any given entity gradually arises out of an infinite series of progressively less dependent entities—it is not wholly transmitted, as it were, from a basic, ungrounded level to all the dependent ones in a step‐by‐step fashion. Some objections are considered and rebutted. 相似文献

探讨肾上腺区局限性Castleman病的临床特点及诊治方法。回顾性分析4例经术后病理证实的肾上腺区局限性 Castle-man病患者的临床资料,并结合文献复习讨论Castleman病的临床特点及诊治方法。结果4例肾上腺区局限性Castleman病均顺利手术切除,术后随访1个月~22个月,未见肿瘤复发。Castleman病临床上少见,表现为不明原因的淋巴结肿大,临床表现无特异性,最终确诊依靠病理诊断。病变可发生在淋巴组织的任何部位,肾上腺区罕见,手术切除为首选治疗。 相似文献

Did you visit the Neuronus conferences in the years 2012 and 2013 in Kraków?
If not, then you certainly should have a close examination of this special issue
including this introduction to at least have a glimpse of an idea of the highly
interesting topics in the field of cognitive neuroscience that were presented at
these conferences. If you were there, it is for sure a good choice to focus on
this special issue as well, first to refresh your minds (we know our memories
are far from perfect), but especially to see what happened with research of the
presenters at these conferences. 相似文献

Abstract The number of occupational therapists and students choosing to practice in the area of mental health continues to decline. A longitudinal comparative study was conducted using a class of 27 Bachelor's and 20 Master's students, to examine the factors that influence the students' practice area preference at three points from pre-admission to job selection. The major influential factors were similar for both groups. At pre-admission, observation, volunteer work or a job in OT or a related field was reported to be the most influential factor in choosing a practice area preference. At level II fieldwork, positive influences on practice area preference were generally higher for physical disabilities, and negative influences were higher for mental health. At job selection, availability of a job and patient population were the most important influencing factors. Pre-admission experiences, level II fieldwork, and professionally challenging aspects of the practice area preference were the most important retrospective experiences influencing preference for practice area. In order to maintain or increase a presence in mental health the profession may need to expand OT students' pre-admission experiential expectations, professional mental health supports, and job opportunities in mental health. 相似文献

Qualitative approaches were used to understand the experience of pregnancy in a group of young Xhosa women (N =10, M age = 19.70, SD = 3.20). Data is provided on their retrospective accounts of factors which contributed towards unwanted pregnancy. Thematic content analysis revealed a range of influences on pregnancy including: background, parenting and restrictions; stigma towards contraception; carelessness and ignorance; power and pressure from the partner; and shifting responsibility. 相似文献

Anomalies of movement are observed both clinically and experimentally in schizophrenia. While the basal ganglia have been implicated in its pathogenesis, the nature of such involvement is equivocal. The basal ganglia may be involved in bimanual coordination through their input to the supplementary motor area (SMA). While a neglected area of study in schizophrenia, a bimanual movement task may provide a means of assessing the functional integrity of the motor circuit. Twelve patients with chronic schizophrenia and 12 matched control participants performed a bimanual movement task on a set of vertically mounted cranks at different speeds (1 and 2 Hz) and phase relationships. Participants performed in-phase movements (hands separated by 0 degrees ) and out-of-phase movements (hands separated by 180 degrees ) at both speeds with an external cue on or off. All participants performed the in-phase movements well, irrespective of speed or cueing conditions. Patients with schizophrenia were unable to perform the out-of-phase movements, particularly at the faster speed, reverting instead to the in-phase movement. There was no effect of external cueing on any of the movement conditions. These results suggest a specific problem of bimanual coordination indicative of SMA dysfunction per se and/or faulty callosal integration. A disturbance in the ability to switch attention during the out-of-phase task may also be involved. 相似文献
