Anopheles mosquitoes are key malaria vectors, their high diversity influences transmission competence. Accurate species identification is crucial for understanding malaria epidemiology and implementing effective vector control strategies. The COX1 gene is a widely used DNA barcoding marker for Anopheles due to its high mutation rate and species-specific variations. This study evaluates the consistency of morphological and molecular identification using COX1, analyzes phylogenetic relationships, and explores the implications of these findings for malaria vector control strategies. Anopheles mosquitoes were collected from Bangsring, Banyuwangi, and Hargowilis, Kulonprogo, Indonesia, two geographically distinct sites with a history of malaria outbreaks. Mosquitoes were collected using human landing catches. Identification was performed morphologically and confirmed by molecular analysis based on COX1 sequences. Phylogenetic tree and genetic distances were analyzed in MEGA11 using the Neighbor-Joining method with the Kimura-2 Parameter model. Morphological and COX1-based identification were mostly consistent; however, specimens identified as Anopheles (An.) aconitus and An. minimus from Hargowilis were molecularly confirmed as An. flavirostris. Phylogenetic analysis revealed eight monophyletic clades with strong bootstrap support (≥99% for six), confirming species groupings. Genetic distance analysis showed An. minimus from Hargowilis clustering more closely with An. flavirostris than with An. minimus from other Asian regions. The dominance of An. sundaicus (68%) in Bangsring and An. flavirostris (13%) in Hargowilis highlights the need for targeted vector control strategies. Misidentification of cryptic Anopheles species may lead to ineffective vector control in specific epidemiological settings. Integrating molecular tools into malaria surveillance can support more accurate species identification and contribute to informed disease prevention strategies.

Zusammenfassung Evaluation und Prognose von Schülerleistungen sind zentrale diagnostische Anforderungen an Lehrkräfte und eine unverzichtbare Voraussetzung für die Individualisierung von Lernprozessen. Hierbei müssen Lehrkräfte gezeigte Leistungen von Schüler:innen bewerten (Evaluation) und zukünftige Leistungen einschätzen können (Prognose). Im Unterrichtsfach Musik gilt dies insbesondere in musikpraktischen Unterrichtssituationen. Die vorliegende Studie geht der Frage nach, wie gut Studierende als angehende Musiklehrkräfte Einzelgesangsleistungen von Schüler:innen einschätzen können und in welchem Maße eine größere Vielfalt an Informationen über deren bisherige Leistung die Genauigkeit der Einschätzungen der Studierenden erhöhen kann. Außerdem wurde untersucht, inwieweit den angehenden Musiklehrkräften die Einschätzung des Anforderungsniveaus ausgewählter Musikstücke in ihrem Prognoseurteil gelingt. Dazu führten wir ein Experiment mit Lehramtsstudierenden durch ( N = 98), bei dem die Niveau‑, Differenzierungs- und Rangkomponente der Urteilsgenauigkeit erfasst wurde. Es zeigte sich, dass ihre Urteilsgenauigkeit im Durchschnitt vergleichbar ist mit derjenigen im Beruf stehender Lehrkräfte anderer Fachrichtungen bei allerdings großer Heterogenität ihrer Urteilsgenauigkeit. Die Variation der Vielfalt der Informationen verbesserte die Genauigkeit der Leistungsprognose nur bei der Rangkomponente.

This study examined the acceptance, feasibility, and sustainability of an individualized family coaching intervention designed to promote behavior modification among children and adolescents with obesity and persons accompanying them during inpatient rehabilitation. The primary aim was to enhance motivation for behavior modification in both patients and their accompanying persons, and to improve the sustainability of rehabilitation outcomes by increasing the involvement of the accompanying persons.This qualitative study was conducted within a single-group pre-post-follow-up design. The study included 31 patients (ages 10-13, 61% female, BMI percentile≥97) and their caregivers. The intervention consisted of three 60-minute family coaching sessions based on the principles of Motivational Interviewing. Thirteen post-intervention focus group interviews with experts, accompanying persons, and patients as well as coaching protocols were analyzed using qualitative content analysis.The coaching was positively evaluated by all participants. Experts perceived that supplementary family coaching helped reduce resistance within families and foster greater personal responsibility compared to group education alone. The accompanying persons reported improved communication with their children and clearer goal setting. Patients appreciated the opportunity to address difficult topics, such as obesity-related behaviors and family conflicts. In the course of the coaching, the accompanying persons demonstrated increasing levels of mobilizing change talk and active engagement. Patients showed an increased intention for behavior change in the course of the coaching.The qualitative findings support the acceptance and feasibility of family coaching in inpatient rehabilitation settings. Implementing a standardized coaching approach could help to sustain rehabilitation outcomes in pediatric obesity. However, sustainable integration requires structural adjustments to ensure frictionless implementation within rehabilitation routines. Future controlled studies should investigate the short- and long-term rehabilitation success of family coaching.

This study explores the potential of solar tracking technologies to enhance South Africa’s energy transition, focusing on their role in supporting green hydrogen production for domestic use and export. Using the Global Energy System Model (GENeSYS-MOD), it evaluates four solar tracking technologies—horizontal axis, tilted horizontal axis, vertical axis, and dual-axis—across six scenarios: tracking and non-tracking versions of a Business-as-Usual (BAU) scenario, a 2 °C scenario, and a high hydrogen demand and export (HighH2) scenario. The results identify horizontal axis tracking as the most cost-effective option, followed by tilted horizontal axis tracking, which is particularly prominent in the HighH2 scenario. Tracking systems enhance hydrogen production by extending power output and increasing electrolyzer full-load hours. In the HighH2 scenario they reduce hydrogen production costs in 2050 from 1.47 €/kg to 1.34 €/kg and system cost by 0.66%, positioning South Africa competitively in the global hydrogen market. By integrating tracking technologies, South Africa can align hydrogen production ambitions with renewable energy growth while mitigating grid and financial challenges. The research underscores the need for targeted energy investments and policies to maximize renewable energy and hydrogen potential, ensuring a just energy transition that supports export opportunities, domestic energy security, and equitable socio-economic growth.

Internate als eine Sozialisationsinstanz gelten bis heute im deutschsprachigen Forschungsdiskurs als Forschungsdesiderat. Allerdings bildet die Rahmung des Aufwachsens von Heranwachsenden im Internat eine prägnante Grundlage für die weitere Entwicklung und die damit verbundene Sozialisation von Kindern und Jugendlichen. Dieser Beitrag nimmt daher die Frage in den Fokus, wie sich sozialisatorische Interaktionen in den Internaten aus Perspektive der Bewohner*innen gestalten. Die Rekonstruktionen zeigen, dass insbesondere die Funktion der Peers als Sozialisationsinstanz und die damit verbundene Konstruktion von Zugehörigkeit bzw. Kollektivismus innerhalb des Internates eine besondere Bedeutung einnimmt. Ausgangspunkt für die Analyse bilden zwei Fallstudien, die an Internaten mit unterschiedlichen Schwerpunkten durchgeführt wurden. Erhoben wurden die Daten durch biographisch-narrative Interviews, Expert*inneninterviews sowie Gruppendiskussionen.

ABSTRACT Participatory processes have become central to environmental governance, particularly in regions undergoing socio-economic transformations due to phase-outs. We examine how power dynamics shape civil society participation in decision-making processes within the context of the German coal phase-out. In the coal region Lusatia, local actor participation is a key factor in selecting projects to be funded with the federal states’ share of the structural reorientation funds. Drawing on semi-structured interviews, we analyze how power was exercised in participatory governance processes in Lusatia and the implications for civil society actors. Findings reveal discrepancies between the rhetoric and implementation of participation: public actors dominate decision-making, relegating non-state actors to a passive role in approving proposals. By highlighting the challenges of participatory governance in contexts characterized by historical economic decline, top-down management, and public disillusionment, our findings contribute to broader debates about the role of power in environmental governance and the politics of phase-out.

Despite evidence indicating that sustainability cannot be achieved without overcoming the economic growth paradigm, current societies continue to pursue destructive growth pathways. Theories on economic growth dependencies and imperatives (GDI) provide explanations for this behaviour by describing mechanisms that cause negative consequences for agents under conditions of zero economic growth. However, conflicting theories exist, impeding concerted efforts to make societal wellbeing independent from economic growth. To address this challenge, we provide a systematic review of 248 publications covering key theories of GDI. The review identifies 112 mechanisms, sorted into 21 clusters and six themes. We provide synthetic conceptual accounts of the diverse dimensions of GDI for each mechanism, such as how harm occurs without growth. We find that GDI mechanisms are more numerous and heterogeneous than previously thought. The analysis of conflicts between the theories shows that disagreements emerge from contradictory perceptions of the neutrality of fundamental social structures. These structures include the monetary economy, market competition, private property and the state. Furthermore, conflicts centre the specific roles of ideology, knowledge and culture. The findings of this comprehensive review highlight the importance of further theoretical and empirical research that deepens our understanding of GDI. • A lack of comprehensive literature reviews on theories of growth dependencies exists. • We cover 248 publications yielding 112 mechanisms in 21 clusters and six themes. • Mechanisms are more numerous and heterogeneous than previously thought. • Conflicts concern the neutrality of fundamental social structures, e.g. private property. • Conflicts also concern the roles of ideology, knowledge and culture.

Kokoomateos sisältää filosofisia esseitä analyyttisen filosofian kolmesta keskeisestä aiheesta: todellisuuden, kielen ja totuuden luonteesta. Lisäksi teos tuo esiin uutta filosofista pohdintaa filosofian perusluonteesta. Teos on omistettu Tampereen yliopiston filosofian professori Panu Raatikaiselle, joka on tuotannossaan käsitellyt edellä mainittuja teemoja ja jolta monet kirjoittajista ovat saaneet oppia ja inspiraatiota. Kokoelma kerää yhteen kirjoituksia merkittäviltä filosofeilta, jotka ovat kohdanneet Raatikaisen erilaisissa akateemisissa yhteyksissä, sekä hänen entisiltä ja nykyisiltä kollegoiltaan. Artikkeleissa käydään kriittistä, rakentavaa vuoropuhelua Raatikaisen keskeisten ajatusten ja argumenttien kanssa.
