Why Listen? Student Voice Work Defended: Students as ‘Expert Witnesses’ to Their Experiences in Schools and Other Sites of Learning
Authors: Groundwater-Smith Susan 
Published: February 2023

AbstractThis chapter makes the case for educative practice in which teachers and learners unite in a form of participative inquiry with an emphasis upon inclusion and social justice. It will demonstrate that taking this stance acts as an interruption to pedagogical power relations and hierarchical governance leading to a reconsideration of the typical assemblages of engagement on the part of all participating in the dance of education. The chapter honours the capability of young people to witness the manner in which educative practices can and should take place in a world worth living in. It will illuminate its assertions by offering a range of examples varying in levels of participation and the scale of the engagement in participative inquiry with a focus upon mutual learning that attends to a variety of voices including those often marginalised, even silenced.
The Heart of the Small Finnish Rural School: Supporting Roots and Wings, Solidarity and Autonomy
Authors: Karlberg-Granlund Gunilla 
Published: February 2023

AbstractThe aim of this chapter is to explore the cultural, educational, and social environment and characteristics of small rural schools, laying a foundation for understanding the possibilities, challenges, and constraints that teachers and pupils may face in these contexts. Questions about what educational quality and equity mean in the rural context underpin the narrative. The inquiry builds on research in some of the smallest rural schools in Finland, schools that might not even exist anymore due to demographic and political reasons. A figure, in the symbolic form of a candle, sums up the pedagogical thinking of rural village school teachers. The candle also illustrates the double purpose of education for living well in a world worth living in. What the small village school teachers articulate as being important in their work and what they wish their pupils would carry with them from the school into their future lives, involves roots and wings, relatedness and autonomy, in coexistence. The culture and education of the small school comprises both the optimal development of the individual and social participation. The small rural school has got a double function as a mediator of education and of community life, i.e. pedagogy and culture.
Elements of spin Hurwitz theory: closed algebraic formulas, blobbed topological recursion, and a proof of the Giacchetto–Kramer–Lewański conjecture
Authors: Alexandrov Alexander , Shadrin Sergey 
Published: February 2023

AbstractIn this paper, we discuss the properties of the generating functions of spin Hurwitz numbers. In particular, for spin Hurwitz numbers with arbitrary ramification profiles, we construct the weighed sums which are given by Orlov’s hypergeometric solutions of the 2-component BKP hierarchy. We derive the closed algebraic formulas for the correlation functions associated with these tau-functions, and under reasonable analytical assumptions we prove the loop equations (the blobbed topological recursion). Finally, we prove a version of topological recursion for the spin Hurwitz numbers with the spin completed cycles (a generalized version of the Giacchetto–Kramer–Lewański conjecture).
Auf dem Weg zur Demokratie – der Transformationsprozess 1990/91 und die Rolle der Gesellschaft für Psychiatrie und Nervenheilkunde in der DDR
Authors: Kumbier Ekkehardt , Haack Kathleen 
Published: February 2023

Zusammenfassung
Ziel
Der Übergang von der sozialistischen Diktatur zu einer liberalen Demokratie in der DDR war mit politischen und gesellschaftlichen Umbrüchen verbunden. Die mit dem demokratisch-gesellschaftspolitischen Prozess einhergehende Transformation wird am Beispiel der Gesellschaft für Neurologie und Psychiatrie der DDR untersucht, die zur Vereinigung mit der Deutschen Gesellschaft für Psychiatrie und Nervenheilkunde (DGPN) führte.

Methodik
Für die historische Untersuchung wurden Archivalien aus dem Archiv der DGPPN wie auch dem persönlichen Besitz damaliger Protagonisten genutzt und Zeitzeugeninterviews geführt.

Ergebnisse
Der Transformationsprozess lässt sich auch für die Gesellschaft für Psychiatrie und Neurologie der DDR feststellen. Wie auf der politischen Ebene kam es 1990 auch auf der Vorstandsebene der Gesellschaft für Psychiatrie und Neurologie zu einem Legitimationsverlust. Das neue Demokratieverständnis erforderte die Beteiligung aller Mitglieder. Der Sprecherrat und die DGPN (Ost) waren zuständig für die Etablierung und Konsolidierung demokratischer Strukturen.

Schlussfolgerung
Über den Transformationsprozess hinaus, ist bisher wenig über das Zusammenwachsen bekannt. Die Phase der Neuorientierung zu Beginn der 1990er-Jahre sollte für die DGPN ebenso untersucht werden wie die Frage nach dem Umgang mit dem vermuteten politischen Missbrauch der Psychiatrie in der DDR.

Abstract
Background
Substance use remains a barrier to recovery for young people accessing early intervention services for psychosis. While correlates of use have been explored in populations experiencing a first episode of psychosis (FEP), sample sizes have been small and less research assesses cohorts at ultrahigh risk of psychosis (UHR).

Methods
This study uses data from a naturalistic cohort including UHR and FEP participants (N = 1252) to elucidate clinical correlates of use in the past 3 months of any illicit substance, amphetamine-type stimulants (ATS), cannabis, and tobacco. Moreover, network analysis based on use of these substances and additionally alcohol, cocaine, hallucinogens, sedatives, inhalants, and opioids was completed.

Results
Young people with FEP used substances at significantly higher rates than those at UHR. High concurrence of use was seen between substances. In the FEP group, participants who had used any illicit substance, ATS, and/or tobacco had increased positive symptoms and decreased negative symptoms. Young people with FEP who used cannabis had increased positive symptoms. In the UHR group, participants who had used any illicit substance, ATS, and/or cannabis in the past 3 months showed decreased negative symptoms compared to those who had not.

Conclusion
A distinct clinical picture of more florid positive symptoms and alleviated negative symptoms seen in those who use substances in the FEP group appears muted in the UHR cohort. Treating young people at UHR in early intervention services represents the earliest opportunity to address substance use early to improve outcomes.

Published: February 2023

Abstract
Objectives
The aim of this study was to compare the prevalence of oral diseases (caries, periodontal disease, enamel defects) between patients with phenylketonuria (PKU), their siblings, and a matched control group.

Materials and methods
A total of 109 patients with PKU, 14 siblings of PKU patients, and 100 healthy individuals aged 6 to 68 years were recruited. All participants completed a questionnaire based on their health status. The patients’ decayed/missing/filled teeth index (dmft/DMFT), gingival bleeding index (GBI), plaque control record (PCR), periodontal screening and recording index (PSR), and developmental enamel defects index (DDE) were recorded. Descriptive statistics and regression modeling were used to examine potential associations between the exposure and the outcomes of interest.

Results
Patients with PKU had 1.6 times more caries (95% confidence interval (CI) 1.22 to 2.20; p = 0.001), seven times more enamel defects (95% CI 3.94 to 14.21; p < 0.001), and four times higher PSR values (95% CI 2.26 to 7.15; p < 0.001) than the control group. The siblings had significantly fewer enamel defects but no significant differences in caries and periodontal parameters compared to the PKU patients.

Conclusions
The results showed a higher risk for the development of caries, periodontitis, and enamel defects in PKU patients.

Clinical relevance
Implementation of preventive measures and regular dental care is necessary for patients with PKU.
COVID-19 and EQ-5D-5L health state valuation
Authors: Webb Edward J. D. , Kind Paul , Meads David , Martin Adam 
Published: February 2023

Abstract
Background
We investigate whether and how general population health state values were influenced by the initial stages of the COVID-19 pandemic. Changes could have important implications, as general population values are used in health resource allocation.

Data
In Spring 2020, participants in a UK general population survey rated 2 EQ-5D-5L states, 11111 and 55555, as well as dead, using a visual analogue scale (VAS) from 100 = best imaginable health to 0 = worst imaginable health. Participants answered questions about their pandemic experiences, including COVID-19’s effect on their health and quality of life, and their subjective risk/worry about infection.

Analysis
VAS ratings for 55555 were transformed to the full health = 1, dead = 0 scale. Tobit models were used to analyse VAS responses, as well as multinomial propensity score matching (MNPS) to create samples balanced according to participant characteristics.

Results
Of 3021 respondents, 2599 were used for analysis. There were statistically significant, but complex associations between experiences of COVID-19 and VAS ratings. For example, in the MNPS analysis, greater subjective risk of infection implied higher VAS ratings for dead, yet worry about infection implied lower ratings. In the Tobit analysis, people whose health was affected by COVID-19 rated 55555 higher, whether the effect on health was positive or negative.

Conclusion
The results complement previous findings that the onset of the COVID-19 pandemic may have impacted EQ-5D-5L health state valuation, and different aspects of the pandemic had different effects.

Abstract
Objective
Quantitative extracellular volume fraction (ECV) mapping with MRI is commonly used to investigate in vivo diffuse myocardial fibrosis. This study aimed to validate ECV measurements against ex vivo histology of myocardial tissue samples from patients with aortic valve stenosis or hypertrophic cardiomyopathy.

Materials and methods
Sixteen patients underwent MRI examination at 3 T to acquire native T1 maps and post-contrast T1 maps after gadobutrol administration, from which hematocrit-corrected ECV maps were estimated. Intra-operatively obtained myocardial tissue samples from the same patients were stained with picrosirius red for quantitative histology of myocardial interstitial fibrosis. Correlations between in vivo ECV and ex vivo myocardial collagen content were evaluated with regression analyses.

Results
Septal ECV was 30.3% ± 4.6% and correlated strongly (n = 16, r = 0.70; p = 0.003) with myocardial collagen content. Myocardial native T1 values (1206 ± 36 ms) did not correlate with septal ECV (r = 0.41; p = 0.111) or with myocardial collagen content (r = 0.32; p = 0.227).

Discussion
We compared myocardial ECV mapping at 3 T against ex vivo histology of myocardial collagen content, adding evidence to the notion that ECV mapping is a surrogate marker for in vivo diffuse myocardial fibrosis.

Published: February 2023

AbstractThe aim of this study was to measure and model the fuel consumption of cut-to-length (CTL) logging machinery in cutting and forwarding under Nordic harvesting conditions, and to clarify which factors had the greatest effect on the fuel consumption. In addition, the total annual fuel consumption and CO2eq emissions were calculated for CTL logging operations in Finland in 2020. The data were collected during a long-term follow-up study on the fuel consumption of harvesters and forwarders conducted between March 2018 and April 2019. The fuel consumption data were obtained from a total of 16 harvesters and 13 forwarders equipped with digital flow metres featuring an accuracy of ± 1% of the fuel volume measured. The engine power of the forest machines explained most of the hour-based fuel consumption. Correspondingly, the harvesting conditions of the forest stand best explained the cubic-metre-based fuel consumption. The fuel consumption of CTL logging operations (cutting and forwarding) averaged 1.4 L m−3 in final felling, and 3.1 and 2.2 L m−3 in first and later thinning, respectively. There was a large variation in the cubic-metre-based fuel consumption between individual machines, both for harvesters and forwarders. The total calculated fuel consumption in Finnish CTL operations in 2020 was 126.6 million L, with the calculated CO2eq emissions totalling 334,209 t (i.e. 5.7 kg m−3). Several measures to accelerate fuel and energy efficiency and reduce CO2eq emissions in CTL logging operations are discussed in the paper.
Secular trends of birthweight in a population of live-born, singletons, without congenital anomalies in Queensland, Australia
Authors: Vilcins Dwan , Baker Peter , Jagals Paul , Sly Peter D. 
Published: February 2023

Abstract
Objectives and importance
Maternal and family patterns are changing, and these changes can influence birthweight. Past research and organisational reports focus on short temporal timelines or broad trends, but trends across a longer temporal period are important. The aim of this study is to assess the trends in birthweight and maternal characteristics across a 19-year period using descriptive statistics.

Study type and methods
Birth records (n = 1,166,055) were obtained for a 19-year period (2000–2019) and a descriptive secular trend analysis was performed.

Results and conclusions
Mean birthweight trended down across the study period, while rates of large for gestational age births increased. This appears to be driven by a decrease in gestational age across the period. Maternal factors, such as smoking, BMI and Indigenous status, were found to be linked with changes in mean birthweight and the proportion of small for gestational age or large for gestational age. More babies were born to older women by the end of the study period. There was a sharp rise in gestational diabetes, and more large for gestational age births to these women. Over time, the large for gestational age births started to decline, suggesting better care practices for women with gestational diabetes.

Published: February 2023

AbstractLow-cost interventions are needed to reduce alcohol use among persons with HIV (PWH) in low-income settings. Brief alcohol interventions hold promise, and technology may efficiently deliver brief intervention components with high frequency. We conducted a costing study of the components of a randomized trial that compared a counselling-based intervention with two in-person one-on-one sessions supplemented by booster sessions to reinforce the intervention among PWH with unhealthy alcohol use in southwest Uganda. Booster sessions were delivered twice weekly by two-way short message service (SMS) or Interactive Voice Response (IVR), i.e. via technology, or approximately monthly via live calls from counsellors. We found no significant intervention effects compared to the control, however the cost of the types of booster sessions differed. Start up and recurring costs for the technology-delivered booster sessions were 2.5 to 3 times the cost per participant of the live-call delivered booster intervention for 1000 participants. These results suggest technology-based interventions for PWH are unlikely to be lower cost than person-delivered interventions unless they are at very large scale.
Moments of Meeting in DMT: Characteristics and Implications from the Subjective Experience of Therapists
Authors: de la Parra López Victoria , Panhofer Heidrun 
Published: February 2023

AbstractMoments of meeting (MoM) are characterized by instances of special intersubjective connection between the therapist and patient which causes a change in the implicit relational knowing (IRK) of both individuals. MoM have been widely described for non-creative arts therapies, but there is little information about their characteristics in dance/movement therapy (DMT). This study seeks to explore and characterize the MoM in DMT from the perception of professional therapists. Nine dance/movement therapists (dmts) were consulted using a multimodal approach that travels between writing and movement (Panhofer, 2011) and data were examined using qualitative content analysis. The results show that the characteristics of MoM can be grouped into three categories: (1) relationship (shared experience, experience of fusion, security and kinesthetic empathy) (2) emotion (emotional intensity and genuine affection) and (3) movement (physical closeness, eye contact, emergency, irruption of the present and release of the flow). These results are contrasted with what was originally proposed by the Boston Group (Lyons-Ruth et al in Infant Ment Health J 19(3):282–289, https://doi.org/10.1002/(sici)1097-0355(199823)19:3<282::aid-imhj3>3.0.co;2-o, 1998) and recently by Duarte et al. (Psychother Res 31:1–14, https://doi.org/10.1080/10503307.2021.1948138, 2021) and Lauffenburger (Am J Dance Ther 42(1):16–32, https://doi.org/10.1007/s10465-020-09321-y, 2020), finding similarities and new elements exclusive to DMT. This work contributes to a deeper understanding and conceptualization of MoM in the specific field of DMT and its clinical practice.
Determination of the doubly symmetric periodic orbits in the restricted three-body problem and Hill’s lunar problem
Authors: Xu Xingbo 
Published: February 2023

AbstractWe review some recent progress on the research of the periodic orbits of the N-body problem, and numerically study the spatial doubly symmetric periodic orbits (SDSPs for short). Both comet- and lunar-type SDSPs in the circular restricted three-body problem are computed, as well as the Hill-type SDSPs in Hill’s lunar problem. Double symmetries are exploited so that the SDSPs can be computed efficiently. The monodromy matrix can be calculated by the information of one fourth period. The periodicity conditions are solved by Broyden’s method with a line-search, and some numerical examples show that the scheme is very efficient. For a fixed period ratio and a given acute angle, there exist sixteen cases of initial values. For the restricted three-body problem, the cases of “Copenhagen problem” and the Sun–Jupiter–asteroid model are considered. New SDSPs are also numerically found in Hill’s lunar problem. Though the period ratio should be small theoretically, some new periodic orbits are found when the ratio is not too small, and the linear stability of the searched SDSPs is numerically determined.
Assessing Writing Motivation: a Systematic Review of K-5 Students' Self-Reports
Authors: Alves-Wold Aline , Walgermo Bente Rigmor , McTigue Erin , Uppstad Per Henning 
Published: February 2023

Abstract
For attaining success in writing, motivation is essential. Crucially, instruction is dependent on knowing the student’s capabilities and inner drives. To date, research on writing has yet to establish a consistent framework for assessing writing motivation, and often fails to acknowledge students’ self-reports, rather favoring evaluations of students’ writing motivation made by others, such as teachers and researchers. This limbo state originates partly from a general skepticism towards the trustworthiness of elementary students’ self-reports. Nonetheless, the validity of such self-reports has been acknowledged in adjacent fields, such as reading. Aiming to establish a knowledge base from studies addressing students’ voices, the present study adopts the method of a systematic review and investigates how writing motivation has been assessed in empirical studies (1996–2020) through K-5 students’ self-reports. Of the 7047 studies identified through database search, 56 met the inclusion criteria and are examined in this review. Results indicate that (a) storytelling is the genre most used to operationalize writing in the investigations, (b) surveys and interview questions measuring students’ attitude towards writing are the most common type of self-report used, and (c) students’ voices are weighted differently across the studies. Findings suggest that future research should (1) work to counteract existing biases in writing tasks, (2) provide a rationale for their choice/design of measure of motivation, and (3) report clearly whose voices are being heard (e.g., students’, teachers’, or researchers’) and the appropriateness of this choice regarding study purpose, design, and findings.
Environmental risk associated with accumulation of toxic metalloids in soils of the Odra River floodplain—case study of the assessment based on total concentrations, fractionation and geochemical indices
Authors: Kawałko Dorota , Karczewska Anna , Lewińska Karolina 
Published: February 2023

AbstractThe floodplain soils are often heavily enriched in metal(loid)s released from the industrial areas. A related environmental risk depends on their total concentrations and the forms and conditions conducive to mobilization. This study was aimed to examine the concentrations of metal(loid)s in the Odra floodplain soils and to assess the risk associated with their possible contamination. In this study, topsoil and deeper soil layer samples were collected from the inter- and out-of-embankment zones. Total concentrations of Pb, Zn, Cu, As, Mn and Fe, and their extractable fractions were determined in 1 M NH4NO3 (actual solubility) and by BCR sequential extraction. The environmental risk was assessed based on total concentrations, according to legal regulations, geochemical enrichment indices and extractability of elements, with considering soil morphological features. Some topsoil samples from the inter-embankment zone turned out considerably enriched in Pb, Zn, Cu, and As, as confirmed by geochemical indices. Zn and As concentrations in some samples exceeded the permissible values defined by Polish law. Zn and Mn showed a high actual solubility, but a simple experiment proved that it can be efficiently reduced by liming. BCR fractionation showed that all the elements occurred mainly in reducible forms. Therefore, the risk of their release from the layers that do not indicate redoximorphic features was assessed as negligible. The study showed that such a complementary approach is needed to assess the real environmental risk in the case of soils considerably enriched in potentially toxic elements.
