The Intricate Relationship between Psychotic-Like Experiences and Associated Subclinical Symptoms in Healthy Individuals
The interplay between subclinical psychotic, negative, and affective symptoms
has gained increased attention regarding the etiology of psychosis spectrum
and other mental disorders. Importantly, research has tended to not
differentiate between different subtypes of psychotic-like experiences (PLE)
although they may not have the same significance for mental health. In order
to gain information on the subclinical interplay between specific PLE and
other symptoms as well as the significance of PLE for mental health, we
investigated their specific associations in 206 healthy individuals (20–60
years, 73 females) using correlational and linear regression analyses. PLE
were assessed with the Magical Ideation Questionnaire, the revised Exceptional
Experiences Questionnaire, and subscales of the Schizotypal Personality
Questionnaire (SPQ). The revised Symptom Checklist 90, the SPQ, and the
Physical Anhedonia Scale were used to measure subclinical negative symptoms,
affective symptoms, and other symptoms such as, emotional instability. As
hypothesized, we found that (1) most affective symptoms and all other
subclinical symptoms correlated positively with all PLE, whereas we found only
partial associations between negative symptoms and PLE. Notably, (2) magical
ideation and paranormal beliefs correlated negatively with physical anhedonia.
In the regression analyses we found (3) similar patterns of specific positive
associations between PLE and other subclinical symptoms: Suspiciousness was a
specific predictor of negative-like symptoms, whereas ideas of reference,
unusual perceptual experiences, and dissociative anomalous perceptions
specifically predicted anxiety symptoms. Interestingly, (4) ideas of reference
negatively predicted physical anhedonia. Similarly, paranormal beliefs were
negatively associated with constricted affect. Moreover, odd beliefs were a
negative predictor of depression, emotional instability, and unspecific
symptoms. Our findings indicated that subtypes of PLE are differentially
implicated in psychological functioning and should therefore not be
categorized homogeneously. Moreover, paranormal beliefs, odd beliefs, and
partly ideas of reference might also contribute to subjective well being in
healthy individuals. Our results might serve as a starting point for
longitudinal studies investigating the interplay of subtypes of subclinical
symptoms along a psychopathological trajectory leading to mental disorders.
Importantly, this research might help to improve therapeutic strategies for
psychosis prevention
Learning together through international collaboration in teacher education in Malaysia. Report of a project to develop a Bachelor of Education (Honours) in Primary Mathematics
Copyright University of Hertfordshire, School of Education 2011Learning together through international collaboration in teacher education in Malaysia is the report of an enterprising partnership between the University of Hertfordshire, UK, the Ministry of Education Malaysia and two Institutes of Teacher Education in Malaysia. Working collaboratively with colleagues in Malaysia, the University of Hertfordshire School of Education designed, validated, supported and quality assured a Bachelor of Education (Honours) degree programme for initial teacher training for a single cohort of 120 students over four years. All the students graduated in 2010. Learning together through international collaboration in teacher education in Malaysia provides a record of the project itself. It also documents in-depth insights from contributors to the project in two main areas: the collaborative approach to working together and issues relating to learning and teaching, including the Action – Reflection – Modelling (ARM) pedagogical approach, which underpinned the degree programme. Senior managers, teacher educators and lecturers share some of their learning from working together to develop and implement the new degree programme. Student teachers voice some experiences from their school placements. They describe how they used ARM; highlight some of the benefits of the approach and identify some of the challenges associated with introducing a different pedagogy in schools as they were 'learning to teach'. There are glimpses of 'lively and attractive' classes in which 'pupils enjoy and feel comfortable to learn' and 'are eager to answer my questions'. School mentors provide additional insights into the student teachers' learning and teaching practice. The richness of the contributions is reflected in the many quotations included in the report. The successful completion of this project was due to the dedication and expertise of many contributors. The findings documented in this report are relevant for all those engaged in international collaboration and teacher education.Final Published versio
Dose–response between frequency of interruption of sedentary time and fasting glucose, the dawn phenomenon and night-time glucose in Type 2 diabetes
Aim: To explore the dose-response between frequency of interruption of sedentary time and basal glucose (fasting glucose, the dawn phenomenon and night-time glucose) in Type 2 diabetes.
Methods: In a randomized three-treatment, two-period balanced incomplete block trial, 12 people with Type 2 diabetes (age, 60.0 +/- 3.2 years; BMI, 30.2 +/- 1.4 kg/m(2)) completed two of three conditions: sitting for 7 h interrupted every 60 min (Condition 1), 30 min (Condition 2), and 15 min (Condition 3) by 3-min light-intensity walking breaks. The activPAL3 and FreeStyle Libre were used to assess physical activity/sedentary behaviour and continuous glucose profile. Standardized meals were provided, and changes in basal glucose of the nights and early mornings before and after treatment conditions were calculated (mean +/- SE).
Results: After treatment conditions, fasting glucose and duration of the dawn phenomenon were lower for Condition 3 (-1.0 +/- 0.2 mmol/l, P < 0.02; -3.1 +/- 1.3 h, P = 0.004) compared with Condition 1 (-0.1 +/- 0.2 mmol/l; 1.9 +/- 1.2 h). The magnitude of the dawn phenomenon was reduced in Condition 3 (-0.6 +/- 0.4 mmol/l, P = 0.041) compared with Condition 2 (0.6 +/- 0.3 mmol/l). Night-time glycaemic variability (coefficient of variation) was reduced in Condition 3 (-9.7 +/- 3.9%) relative to Condition 2 (6.1 +/- 4.8%, P < 0.03) and Condition 1 (2.5 +/- 1.8%, P = 0.02). There was no change in night-time mean glucose.
Conclusions: Frequent interruptions of prolonged sitting with 3 min of light-intensity walking breaks every 15 min improves fasting glucose, the dawn phenomenon and night-time glycaemic variability, and this might be a simple therapeutic intervention to improve glucose control.

Phase transitions during formation of Ag nanoparticles on In2S3 precursor layers
Phase transitions have been investigated for silver deposition onto In2S3
precursor layers by spray chemical vapor deposition from a trimethylphosphine
(hexafluoroacetylacetonato) silver (Ag(hfacac)(PMe3)) solution. The formation
of Ag nanoparticles (Ag NPs) on top of the semiconductor layer set on
concomitant with the formation of AgIn5S8. The increase of the diameter of Ag
NPs was accompanied by the evolution of orthorhombic AgInS2. The formation of
Ag2S at the interface between Ag NPs and the semiconductor layer was observed.
Surface photovoltage spectroscopy indicated charge separation and electronic
transitions in the ranges of corresponding band gaps. The phase transition
approach is aimed to be applied for the formation of plasmonic nanostructures
on top of extremely thin semiconducting layers
Beyond national climate action : the impact of region, city, and business commitments on global greenhouse gas emissions
This article quantifies the net aggregate impact in 2030 of commitments by individual non-state and subnational actors (e.g. regions, cities and businesses, collectively referred to as ‘NSAs’) to reduce greenhouse gas (GHG) emissions. The analysis was conducted for NSAs operating within ten major emitting economies that together accounted for roughly two-thirds of global GHG emissions in 2016. Our assessment includes 79 regions (e.g. subnational states and provinces), approximately 6,000 cities, and nearly 1,600 companies with a net emissions coverage of 8.1 GtCO2e/year, or a quarter of the ten economies’ total GHG emissions in 2016. The analysis reflects a proposed methodology to aggregate commitments from different subnational (i.e. regional and city government) and non-state (i.e. business) actors, accounting for overlaps. If individual commitments by NSAs in the ten high-emitting economies studied are fully implemented and do not change the pace of action elsewhere, projected GHG emissions in 2030 for the ten economies would be 1.2–2.0 GtCO2e/year or 3.8%–5.5% lower compared to scenario projections for current national policies (31.6–36.8 GtCO2e/year). On a country level, we find that the full implementation of these individual commitments alone could result in the European Union and Japan overachieving their nationally determined contributions (NDCs), while India could further overachieve its unconditional NDC target. In the United States, where the national government has rolled back climate policies, NSAs could become a potential driving force for climate action. Key policy insights Full implementation of reported and quantifiable individual commitments by regions, cities and businesses (NSAs) in ten major economies could reduce emissions by 3.8%–5.5% in 2030 below current national policies scenario projections. National governments’ mitigation targets could be more ambitious if they would take NSA commitments into account. With full implementation of such action, the European Union and Japan would overachieve their NDC targets. For the United States such action could help meeting its original 2025 NDC target in spite of rollbacks in national climate policies. The full universe of NSA climate action expands far beyond the subset of commitments analysed in this study; NSAs could become a strong driving force for enhanced action towards the Paris climate goals.</p
Association of male hypogonadism with risk of hospitalization for COVID-19
Importance: Male sex is associated with severe COVID-19. It is not known whether the risk of hospitalization differs between men with hypogonadism, men with eugonadism, and those receiving testosterone therapy (TTh).
Objective: To compare COVID-19 hospitalization rates for men with hypogonadism who were not receiving TTh, men with eugonadism, and men receiving TTh.
Design, Setting, and Participants: This cohort study was conducted in 2 large academic health systems in St Louis, Missouri, among 723 men with a history of COVID-19 who had testosterone concentrations measured between January 1, 2017, and December 31, 2021.
Exposures: The primary exposure was gonadal status (hypogonadism, eugonadism, and TTh). Hypogonadism was defined as a total testosterone concentration below the limit of normal provided by the laboratory (which varied from 175 to 300 ng/dL [to convert to nanomoles per liter, multiply by 0.0347]).
Main Outcomes and Measures: The primary outcome was rate of hospitalization for COVID-19. Statistical adjustments were made for group differences in age, body mass index, race and ethnicity, immunosuppression, and comorbid conditions.
Results: Of the 723 study participants (mean [SD] age, 55 [14] years; mean [SD] body mass index, 33.5 [7.3]), 116 men had hypogonadism, 427 had eugonadism, and 180 were receiving TTh. Men with hypogonadism were more likely than men with eugonadism to be hospitalized with COVID-19 (52 of 116 [45%] vs 53 of 427 [12%]; P \u3c .001). After multivariable adjustment, men with hypogonadism had higher odds than men with eugonadism of being hospitalized (odds ratio, 2.4; 95% CI, 1.4-4.4; P \u3c .003). Men receiving TTh had a similar risk of hospitalization as men with eugonadism (odds ratio, 1.3; 95% CI, 0.7-2.3; P = .35). Men receiving inadequate TTh (defined as subnormal testosterone concentrations while receiving TTh) had higher odds of hospitalization compared with men who had normal testosterone concentrations while receiving TTh (multivariable adjusted odds ratio, 3.5; 95% CI, 1.5-8.6; P = .003).
Conclusions and Relevance: This study suggests that men with hypogonadism were more likely to be hospitalized after COVID-19 infection compared with those with eugonadism, independent of other known risk factors. This increased risk was not observed among men receiving adequate TTh. Screening and appropriate therapy for hypogonadism need to be evaluated as a strategy to prevent severe COVID-19 outcomes among men
