Semantic coherence in psychometric schizotypy: An investigation using Latent Semantic Analysis

Technological advancements have led to the development of automated methods for assessing semantic coherence in psychiatric populations. Latent Semantic Analysis (LSA) is an automated method that has been used to quantify semantic coherence in schizophrenia-spectrum disorders. The current study examined whether: 1) Semantic coherence reductions extended to psychometrically-defined schizotypy and 2) Greater cognitive load further reduces semantic coherence. LSA was applied to responses generated during category fluency tasks in baseline and cognitive load conditions. Significant differences between schizotypy and non-schizotypy groups were not observed. Findings suggest that semantic coherence may be relatively preserved at this point on the schizophrenia-spectrum

Measuring patient's expectation and the perception of quality in LASIK services

<p>Abstract</p> <p>Background</p> <p>LASIK is the use of excimer lasers to treat therapeutic and refractive visual disorders, ranging from superficial scars to nearsightedness (myopia), and from astigmatism to farsightedness (hyperopia). The purposes of this study are to checking the applicability and psychometric properties of the SERVQUAL on Lasik surgery population. Second, use SEM methods to investigate the loyalty, perceptions and expectations relationship on LASIK surgery.</p> <p>Methods</p> <p>The method with which this study was conducted was questionnaire development. A total of 463 consecutive patients, attending LASIK surgery affiliated with Chung Shan Medical University Eye Center, enrolled in this study. All participants were asked to complete revised SERVQUAL questionnaires. Student t test, correlation test, and ANOVA and factor analyses were used to identify the characters and factors of service quality. Paired t test were used to test the gap between expectation and perception scores and structural equation modeling was used to examine relationships among satisfaction components.</p> <p>Results</p> <p>The effective response rate was 97.3%. Validity was verified by several methods and internal reliability Cronbach's alpha was > 0.958. The results from patient's scores were very high with an overall score of 6.41(0.66), expectations at 6.68(0.47), and perceptions at 6.51(0.57). The gap between expectations and perceptions was significant, however, (t = 6.08). Furthermore, there were significant differences in the expectation scores among the different jobs. Also, the results showed that the higher the education of the patient, the lower their perception score (r = -0.10). The factor loading results of factor analysis showed 5 factors of the 22 items of the SERVQUAL model. The 5 factors of perception explained 72.94% of the total variance there; and on expectations it explained 77.12% of the total variance of satisfaction scores.</p> <p>The goodness-of-fit summary, of structure equation modeling, showed trends in concept on expectations, perceptions, and loyalty.</p> <p>Conclusion</p> <p>The results of this research appear to show that the SERVQUAL instrument is a useful measurement tool in assessing and monitoring service quality in LASIK service, and enabling staff to identify where improvements are needed, from the patients' perspective. There were service quality gaps in the reliability, assurance, and empathy. This study suggested that physicians should increase their discussions with patients; which has, of course, already been proven to be an effective way to increase patient's satisfaction with medical care, regardless of the procedure received.</p

The Science Performance of JWST as Characterized in Commissioning

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

Anti-Poverty Medicine Through Medical-Financial Partnerships: A New Approach to Child Poverty.

Poverty threatens child health. In the United States, financial strain, which encompasses income and asset poverty, is common with many complex etiologies. Even relatively successful antipoverty programs and policies fall short of serving all families in need, endangering health. We describe a new approach to address this pervasive health problem: antipoverty medicine. Historically, medicine has viewed poverty as a social problem outside of its scope. Increasingly, health care has addressed povertys downstream effects, such as food and housing insecurity. However, strong evidence now shows that poverty affects biology, and thus, merits treatment as a medical problem. A new approach uses Medical-Financial Partnerships (MFPs), in which healthcare systems and financial service organizations collaborate to improve health by reducing family financial strain. MFPs help families grow assets by increasing savings, decreasing debt, and improving credit and economic opportunity while building a solid foundation for lifelong financial, physical, and mental health. We review evidence-based approaches to poverty alleviation, including conditional and unconditional cash transfers, savings vehicles, debt relief, credit repair, financial coaching, and employment assistance. We describe current national MFPs and highlight different applications of these evidence-based clinical financial interventions. Current MFP models reveal implementation opportunities and challenges, including time and space constraints, time-sensitive processes, lack of familiarity among patients and communities served, and sustainability in traditional medical settings. We conclude that pediatric health care practices can intervene upon poverty and should consider embracing antipoverty medicine as an essential part of the future of pediatric care
