Sleep, Well-Being and Academic Performance: A Study in a Singapore Residential College
No full textWe examined the relationship between sleep and the affective components of subjective well-being as well as psychological well-being, and between sleep and academic performance, of full-time undergraduate students in a residential college at the National University of Singapore. The aspects of sleep considered were self-reported sleep duration, sleep efficiency, frequency of sleep disturbances, daytime dysfunction, sleep latency and overall sleep quality, as measured by the Pittsburgh Sleep Quality Index. Academic performance was measured using self-reported cumulative average point scores, typically known as grade point average in other institutions. Psychological well-being and the affective components of subjective well-being were assessed using the Flourishing Scale and the Scale of Positive and Negative Experience, respectively. With the exception of sleep latency, our univariate analysis revealed significant associations between the abovementioned facets of sleep, and the affective components of subjective well-being. The analysis also revealed significant associations between the above sleep variables and psychological well-being, except sleep latency and frequency of sleep disturbances. Only daytime dysfunction was found to be significantly correlated with academic performance in our univariate analysis. In addition, our multivariate analysis shows that psychological well-being, affect balance and academic performance each has a direct effect on overall sleep quality. The relationship between overall sleep quality and psychological well-being is U-shaped, while that between overall sleep quality and affect balance is linear and moderated by psychological well-being. The relationship between overall sleep quality and academic performance is either U-shaped or an inverted-U, depending on the level of psychological well-being, which moderates the relationship. These nonlinear relationships indicate that individuals with the highest levels of psychological well-being are not the best sleepers (in terms of overall sleep quality), neither are the highest academic achievers necessarily the best sleepers
Exploring ChatGPT's communication behaviour in healthcare interactions: A psycholinguistic perspective
No full textObjectives: Conversational artificial agents such as ChatGPT are commonly used by people seeking healthcare information. This study investigates whether ChatGPT exhibits distinct communicative behaviors in healthcare settings based on the nature of the disorder (medical or psychological) and the user communication style (neutral vs. expressing concern). Method: Queries were conducted with ChatGPT to gather information on the diagnosis and treatment of two conditions (arthritis and anxiety) using different styles (neutral vs. expressing concern). ChatGPT's responses were analyzed using Linguistic Inquiry and Word Count (LIWC) to identify linguistic markers of the agent's adjustment to different inquiries and interaction modes. Statistical analyses, including repeated measures ANOVA and k-means cluster analysis, identified patterns in ChatGPT's responses. Results: ChatGPT used more engaging language in treatment contexts and psychological inquiries. It exhibited more analytical thinking in neutral contexts while demonstrating higher levels of empathy in psychological conditions and when the user expressed concern. Wellness-related language was more prevalent in psychological and treatment contexts, whereas illness-related language was more common in diagnostic interactions for physical conditions. Cluster analysis revealed two distinct patterns: high empathy and engagement in psychological/expressing-concern scenarios, and lower empathy and engagement in neutral/physical disease contexts. Conclusions: These findings suggest that ChatGPT's responses vary according to disorder type and interaction context, potentially improving its effectiveness in patient engagement. Practice implications: Through context and user-concern language adaptation, ChatGPT can enhance patient engagement
STUDY OF CHARMONIUM RESONANCES IN THE GAMGAM -> K0S K+PI- AND GAMGAM -> K+K-PI+PI-PI0 PROCESSES
No full textWe study charmonium resonances produced via two-photon interactions and decaying to the K0S K+ PI- and K+ K- PI+ PI- PI0 final states, using data collected by the BaBar experiment, located at the PEP-II asymmetric e+e- storage ring at SLAC National Accelerator Laboratory.
We observe the eta_c(1S), chi_c0(1P) and
eta_c(2S) resonances produced in two-photon interactions and
decaying to K+ K- PI+ PI- PI0, with significances of 18.1, 5.4 and
5.3 standard deviations (including
systematic errors), respectively, and report 4.0sigma evidence of
the chi_c2(1P) decay to this final state.
We measure the eta_c(2S)mass and width in K0S K+ PI- decays, and
obtain the values m(eta_c(2S))= 3638.5 +/- 1.5 +/- 0.8 MeV/c^2 and
Gamma(eta_c(2S)) = 13.4 +/- 4.6 +/- 3.2 MeV, where
the first uncertainty is statistical and the second is systematic.
We measure the two-photon width times branching
fraction for the reported resonance signals, and search for
the chi_c2(2P) resonance, but no significant signal
is observed
Travel Experience and Reasons for the Use and Nonuse of Local Public Transport: A Case Study within the Community Interregional Project SaMBA (Sustainable Mobility Behaviors in the Alpine Region)
No full textKnowing the reasons for mobility choices, how users evaluate the characteristics of public transport and how satisfied they are with their travel experience is essential to promote the use of LPT (local public transport), especially in rural or suburban areas where the use of private cars is often prevalent. The present study aimed to investigate the mobility experience and the reasons for use and nonuse of the LPT in a suburban area by the people traveling to a large hospital center in a province of the north-east of Italy. An anonymous questionnaire was completed by people from different categories traveling to the hospital (students, employees, clients), who were user and nonusers of the LPT. The results showed that insufficient hourly coverage and accessibility of the service are the primary reasons for opting not to use LPT and, together with reliability and comfort, these factors contribute to user satisfaction with their travel experience. The perceived sustainability of LPT contributes to overall travel satisfaction. However, perceived sustainability alone does not appear to influence the choice of LPT if the service lacks adequate accessibility and does not meet the needs of travelers in terms of hourly coverage
SDDs for high-rate and high-resolution electron spectroscopy
No full textSilicon Drift Detectors (SDDs) are a promising technology for electron spectroscopy, due to their excellent energy resolution and capability to sustain high interaction rate. We present a model based on a Geant4 simulation for the electron response. We then investigate the possibility to use a SDD as a versatile and compact spectrometer that can be operated with standard technologies
High-resolution transmission spectroscopy of the hot-Saturn HD 149026b
No full textAdvances in modern technology have enabled the characterization of exoplanetary atmospheres, which can be achieved by exploitation of the transmission spectroscopy technique. We performed visible (VIS) and near-infrared (NIR) high-resolution spectroscopic observations of one transit of HD 149026b, a close-in orbit sub-Saturn exoplanet by using the GIARPS configuration at the Telescopio Nazionale Galileo (TNG). We first analyzed the radial-velocity data, refining the value of the projected spin-orbit obliquity (λ). We then performed transmission spectroscopy, looking for absorption signals from the planetary atmosphere. We find no evidence for Hα, Na
Molecular picture of community- and healthcare-associated methicillin-resistant Staphylococcus aureus circulating in a teaching hospital in Milan
No full textThe epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) has dramatically changed over the past 10 y with the emergence of community-associated MRSA (CA-MRSA). Recent studies have reported a frequent association of these strains with hospital outbreaks, and an incidence varying over time and by region. In order to evaluate the MRSA lineages circulating in our area of Italy, we performed a molecular characterization of CA-MRSA isolates prospectively collected from April 2006 to July 2007 at the San Paolo Hospital of Milan. We investigated the protein A-encoding gene (spa-typing), the staphylococcal chromosomal cassette SCCmec, the presence of Panton–Valentine leukocidin (PVL), and 3 adhesin genes. Twenty-five CA-MRSA isolates cultured from 25 patients were collected; an equal number of healthcare-associated (HA)-MRSA strains, from 25 patients hospitalized in various wards, were collected for comparison purposes. SCCmec type IV emerged as the most frequent genotype in both CA- and HA-MRSA. Seventeen different spa types were identified: t515 was the most common (36%), followed by t008 (20%). We detected 3 PVL-positive strains, only among the CA-MRSA. On the whole, our local MRSA epidemiology appears to be heterogeneous, with a predominant t515 spa type, only recently considered to belong to clonal EMRSA-15
