Normal Speech

SummaryPrevious research suggests, though by no means consistently, that schizophrenic patients may be less able than normals to predict the speech of other people, and that schizophrenic speech is less predictable than normal speech. The present experiment tests these two suggestions and also a third possibility, that the difference between schizophrenic and normal speech is less marked for schizophrenics asked to make the predictions than for normals. Twelve schizophrenic patients recently admitted to hospital, and twelve comparable, psychiatrically normal, orthopaedic patients, were asked to predict both schizophrenic and normal speech, using Cloze Procedure, under both fourth-word and fifth-word deletion. The first hypothesis was upheld, but the second and third received only very limited support. The findings are discussed in the light of previous work, and suggestions are made for future research.

Normal Speech

SummaryPrevious research has suggested that schizophrenic speech is less predictable than normal speech. Two experiments designed to test the suggestion are reported, both of them based on Cloze Procedure. In the first, raters were asked to predict ten passages of schizophrenic speech and ten passages of normal speech under fourth-word deletion. No difference between the two types of passage was found. In the second, a modified form of presentation was introduced which prevented raters making use of the text which follows a blank. Once again, no difference was revealed between the schizophrenic and normal passages, and this was true for both the new and traditional forms of presentation, and for both fourth-word and fifth-word deletion patterns. The investigation is discussed in the light of previous findings, and a number of suggestions concerning methodology and forms of analysis are made for future research.

SummaryPrevious research has resulted in inconsistent findings regarding the predictability of schizophrenic speech samples. It was hypothesized that the predictability of schizophrenic speech varies as a function of clinically manifest thought disorder. In an experiment based on the Cloze procedure, raters were asked to predict ten passages of schizophrenic speech and eight passages of normal speech under conditions of fourth- and fifth-word deletion. Differences emerged between the samples only for the fifth-word deletion procedure. When the schizophrenic samples were grouped according to the presence of thought disorder, thought-disordered speech was significantly less predictable than normal and non-thought disordered schizophrenic speech. Furthermore, non-thought-disordered schizophrenic speech was no less predictable than normal speech. It is concluded that schizophrenia should be more carefully defined and that thought disorder should be routinely assessed in future investigations.

The Difference

Purpose Augmentative and alternative communication (AAC) is an intervention approach that can promote communication and language in children with multiple disabilities who are beginning communicators. While a wide range of AAC technologies are available, little is known about the comparative effects of specific technology options. Given that engagement can be low for beginning communicators with multiple disabilities, the current study provides initial information about the comparative effects of 2 AAC technology options—high-tech visual scene displays (VSDs) and low-tech isolated picture symbols—on engagement. Method Three elementary-age beginning communicators with multiple disabilities participated. The study used a single-subject, alternating treatment design with each technology serving as a condition. Participants interacted with their school speech-language pathologists using each of the 2 technologies across 5 sessions in a block randomized order. Results According to visual analysis and nonoverlap of all pairs calculations, all 3 participants demonstrated more engagement with the high-tech VSDs than the low-tech isolated picture symbols as measured by their seconds of gaze toward each technology option. Despite the difference in engagement observed, there was no clear difference across the 2 conditions in engagement toward the communication partner or use of the AAC. Conclusions Clinicians can consider measuring engagement when evaluating AAC technology options for children with multiple disabilities and should consider evaluating high-tech VSDs as 1 technology option for them. Future research must explore the extent to which differences in engagement to particular AAC technologies result in differences in communication and language learning over time as might be expected.

Summary141 patients with an ICD-9 diagnosis of schizophrenic psychosis were followed up prospectively for 3 years in 7 Italian centres, representative of the different degrees of application of the psychiatric reform law (Law 180) passed in 1978. It was agreed that each centre would treat the patients according to its routine, and that all contacts with the patients and each intervention performed would be carefully recorded in an ad hoc schedule. The baseline evaluation of psychosocial adjustment was performed by the Disability Assessment Schedule (DAS), and this assessment was then repeated every 6 months during the follow-up period. At the end of this period, the rating on the DAS section 5 was taken as a global measure of patients’ psychosocial outcome. On a stepwise logistic regression analysis, 2 variables were found to be significantly predictive of psychosocial outcome, that is the use of social and/or vocational skills training (associated with a favourable outcome) and the number of days/year of full hospitalization (associated with a poor outcome). Trieste and Arezzo were the only centres in which a significant improvement of the score on some DAS subscales (namely, “occupational role, interest” and “social withdrawal”) was detected. In the whole patient sample, the difference between the final and the baseline score on these subscales correlated significantly with the number/year of outpatient contacts and of home visits. These findings confirm the favourable impact of the community-oriented care provided in some Italian centres on the Psychosocial outcome of schizophrenic patients.

The purpose of this article was to demonstrate the difference between a pandemic plan’s textual prescription and its effective processing using graphical notation. Before creating a case study of the Business Process Model and Notation (BPMN) of the Czech Republic’s pandemic plan, we conducted a systematic review of the process approach in pandemic planning and a document analysis of relevant public documents. The authors emphasized the opacity of hundreds of pages of text records in an explanatory case study and demonstrated the effectiveness of the process approach in reengineering and improving the response to such a critical situation. A potential extension to the automation and involvement of SMART technologies or process optimization through process mining techniques is presented as a future research topic.

AbstractThe purpose of this study was to compare the effectiveness of three methods used to assist in teaching molecular geometry to college chemistry students. A pre- and post-test quasi-experiment was used to collect data about students’ performance in a given chemistry exercise. One research question was intended to evaluate and compare the effectiveness of the three methods in assisting students to understand the topic and carry out the exercise correctly, and a second research question addressed students’ attitudes towards the use of Virtual Reality (VR) in chemistry education. Results show a positive attitude towards the use of VR as an assisting tool to aid in understanding chemistry concepts. While the difference among the three methods was not significant, the results show that the VR brought more enthusiasm and positive attitudes toward the topic of molecular geometry among the students. Educational implications and recommendations for future research are presented as well.

Abstract How can one assess which countries select more experienced leaders for the highest office? There is wide variation in prior career paths of national leaders within, and even more so between, regime types. It is therefore challenging to obtain a truly comparative measure of political experience; empirical studies have to rely on proxies instead. This article proposes PolEx, a measure of political experience that abstracts away from the details of career paths and generalizes based on the duration, quality and breadth of an individual's experience in politics. The analysis draws on a novel data set of around 2,000 leaders from 1950 to 2017 and uses a Bayesian latent variable model to estimate PolEx. The article illustrates how the new measure can be used comparatively to assess whether democracies select more experienced leaders. The authors find that while on average they do, the difference with non-democracies has declined dramatically since the early 2000s. Future research may leverage PolEx to investigate the role of prior political experience in, for example, policy making and crisis management.

As an effective tool to unify discrete and continuous analysis, time scale calculus have been widely applied to study dynamic systems in both theoretical and practical aspects. In addition to such a classical role of unification, the dynamic equations on time scales have their own unique features which the difference and differential equations do not possess and these advantages have been highlighted in describing some complicated dynamical behavior in the hybrid time process. In this review article, we conduct a survey of abstract analysis and applied dynamic equations on hybrid time scales, some recent main results and the related developments on hybrid time scales will be reported and the future research related to this research field is discussed. The results presented in this article can be extended and generalized to study both pure mathematical analysis and real applications such as mathematical physics, biological dynamical models and neural networks, etc.

This study aims to investigate the literature in product distribution and channel competition. In this study, past work related to the product distribution through different channels is extensively reviewed. Based on the channel differentiation, channel competition is also reviewed. Finally, the study proposes that the future research may focus on helping the producer make a decision whether to sell the product through its own direct channel (online) through a physical channel or both based on the difference between these two channels.

In the operating theatre, anesthesiologists monitor an anesthetized patient’s oxygen saturation (SpO2) with a visual display but also with an auditory tone, or sonification. However, if the anesthesiologist must divide their attention across tasks, they may be less effective at recognising their patient’s SpO2 level. Previous research indicates that a sonification enhanced with additional sound dimensions of tremolo and brightness more effectively supports participants’ identification of SpO2 ranges than a conventional sonification does. This laboratory study explored the effect of a secondary task on participants’ ability to identify SpO2 range when using a conventional sonification (LogLinear sonification) versus an enhanced sonification (Stepped Effects sonification). Nineteen non-clinician participants who used the Stepped Effects sonification were significantly more effective at identifying SpO2 range ( Md = 100%) than were 18 participants using the LogLinear sonification ( Md = 80%). Range identification performance of participants using the Stepped Effects sonification tended to be less disrupted by a concurrent arithmetic task (drop from Md = 100% to 95%) than it was for participants using the LogLinear sonification (drop from Md = 80% to 73%). However, the disruption effect in each case was small, and the difference in disruption across sonifications was not statistically significant. Future research will test the sonifications under more intense cognitive load and in the presence of ambient noise.
