Tailored charge-neutral self-assembled L2Zn2 container for taming oxalate.

Dicarboxylic acids and their derivatives play crucial roles in various biological processes, necessitating the development of effective receptors for their detection. In particular, the smallest dicarboxylate, oxalate, presents a significant importance due to its widespread presence in nature and its association with various diseases. Yet, very little attention was devoted to the recognition of oxalate with metal-driven self-assemblies like cages or containers while numerous classic organic receptors for oxalate exist. This discrepancy is astonishing because metallocontainers or metallocages have advantages over classic macrocycles or organocages like a higher modularity and good preorganization paired with a ready receptor preparation by metal complexation. The reason for the underrepresentation is the competitive nature and excellent ligand properties of oxalate which not only is associated with the aforementioned diseases but also poses a serious hazard for metal-driven self-assemblies because the dianion can easily replace ligand strands leading to a partial or full receptor decomposition. Herein, we present a charge-neutral zinc(II)-based metallocontainer which was tuned to contest oxalate as most competitive dicarboxylate. The dianion is bound in a 1:1 fashion with a binding constant of log K = 4.39 selectively over other dicarboxylates by maintaining the receptor stability. This study highlights the importance of a highly modular receptor design so that tailored hosts can be designed to tackle the recognition of challenging competitive analytes.

Practitioners’ Experiences of School Readiness in Rural Early Childhood Centres in QwaQwa Free State, South Africa

The analysis of the school preparation experiences of rural early childhood practitioners. Multiple complex issues exist regarding school preparedness in South Africa. Research has found that many South African children are unprepared for formal schooling. Some of the challenges experienced by these young learners were low reading strength, learning setbacks and complications, and sluggish general development. As a result of these issues, young children face long-term repercussions. These include the inability to escape the cycle of poverty, lack of educational support, and poor socioeconomic conditions within their environment. Therefore, it can be argued that teaching within the South African public schooling context is marred with difficulties and unforeseen challenges. It is difficult to imagine how to modify South African infrastructure so all children can reach their full potential. Given that our ancient past is still rife with historical and power changes, the government must consider several factors while developing ways to aid transformation. This study investigated the perspectives of practitioners on school preparedness. At the same time, it investigates the significant learning at the grass-roots level that emerged from participation in a critical paradigm-based participatory action research project. The study is anchored in a philosophical methodology that leverages Practitioners’ idea that early childhood learners are ready for formal school. They do not emphasize play as a pedagogy for learning in preparation for school readiness. This paper is grounded in constructivism, which helps comprehend how school readiness knowledge improves formal education for young students. The author used the qualitative research approach with an interpretive paradigm to explore practitioners’ school readiness experiences. The author developed a semi-structured interview schedule to collect data from six practitioners in the Thabo-Mofutsanyana district in the Free State Province. The findings revealed practitioners lacked appropriate training and support in preparing young learners in ECD centres. Furthermore, practitioners lacked appropriate pedagogical skills to strengthen teaching and learning. The study recommended that practitioners receive ongoing professional teacher development in school readiness and use various teaching and learning strategies such as play pedagogy.

Comparing efficiencies of population control methods for responding to introductions of transboundary animal diseases in wild pigs

Introductions of transboundary animal diseases (TADs) into free-ranging wildlife can be difficult to control and devastating for domestic livestock trade. Combating a new TAD introduction in wildlife with an emergency response requires quickly limiting spread of the disease by intensely removing wild animals within a contiguous area. In the case of African swine fever virus (ASFv) in wild pigs (Sus scrofa), which has been spreading in many regions of the world, there is little information on the time- and cost-efficiency of methods for intensively and consistently culling wild pigs and recovering carcasses in an emergency response scenario. We compared the efficiencies of aerial operations, trapping, experimental toxic baiting, and ground shooting in northcentral Texas, USA during two months in 2023. Culling and recovering carcasses of wild pigs averaged a rate of 0.15 wild pigs/person hour and cost an average of $233.04/wild pig ($USD 2023) across all four methods. Aerial operations required the greatest initial investment but subsequently was the most time- and cost-efficient, costing an average of $7266 to reduce the population by a standard measure of 10 %, including recovering carcasses. Aerial operations required a ground crew of ∼7 people/helicopter to recover carcasses. Costs for reducing the population of wild pigs using trapping were similar, although took 13.5 times longer to accomplish. In cases where carcass recovery and disposal are needed (e.g., response to ASFv), a benefit of trapping was immediate carcass recovery. Toxic baiting was less efficient because both culling and carcass recovery required substantial time. We culled very few wild pigs with ground shooting in this landscape. Our results provide insight on the efficiencies of each removal method. Strategically combining removal methods may increase overall efficiency. Overall, our findings inform the preparation of resources, personnel needs, and deployment readiness for TAD responses involving wild pigs.

Strategies of Kindergarten Teachers and Parents in Preparing Children's School Readiness: Academic, Social, and Emotional Perspectives

Purpose – This study aims to investigate the strategies employed by kindergarten teachers and parents in preparing children's school readiness in the Batang Angkola District, considering the local context and related social dynamics. Design/methods/approach – Utilizing a qualitative descriptive method, the research combines a descriptive approach to outline existing phenomena with a qualitative approach to explore the meanings and interpretations of the strategies used. Data were collected through direct interviews with several kindergarten teachers and parent representatives in kindergartens and surrounding areas in the Batang Angkola District. Additionally, secondary data related to supporting theories on children's school readiness were utilized. Findings – The findings reveal that both kindergarten teachers and parents are not fully prepared for children's school readiness. This is evidenced by the non-alignment of teachers' educational backgrounds with early childhood education and the parents' primary focus on academic readiness, often neglecting other critical aspects such as social and emotional development. Furthermore, the strategies implemented by kindergarten teachers and parents fail to holistically address the needs of children during the transition process. Research implications/limitations – The study is limited to the Batang Angkola District and may not be generalizable to other regions. These findings highlight areas in educational practices that require improvement and suggest the need for further research to develop more effective strategies for holistic school readiness preparation. Practical implications – The insights gained from this study provide guidance for the development of more holistic and integrated school readiness preparation programs that can better support children during their transition to school. These programs should aim to balance academic learning with social, emotional, and physical development to ensure well-rounded preparedness. Originality/value – This research sheds light on the specific challenges faced by kindergarten teachers and parents in the Batang Angkola District, emphasizing the importance of a holistic approach to school readiness that includes academic, social, and emotional aspects. By addressing these challenges, the study contributes to the broader understanding of effective strategies for early childhood education in similar contexts. Paper type Case study

Design and Synthesis of Cofacially-Arrayed Polyfluorene Wires for Electron and Energy Transfer Studies.

A study of cofacially arrayed π-systems is of particular importance for the design of functional materials for efficient long-range intra-chain charge transfer through the bulk semiconducting materials in the layers of photovoltaic devices. The effect of π-stacking between a pair of aromatic rings has been mainly studied in the form of cyclophanes, where aromatic rings are forced into a sandwich-like geometry, which extensively deforms the aromatic rings from planarity. The synthetic difficulties associated with the preparation of cyclophane-like structures has prevented the synthesis of many examples of their multi-layered analogues. Moreover, the few available multi-layered cyclophanes are not readily amenable to the structural modification required for the construction of D-spacer-A triads needed to explore mechanisms of electron and energy transfer. In this review, we recount how a detailed experimental and computational analysis of 1,3-diarylalkanes led to the design of a new class of cofacially arrayed polyfluorenes that retain their π-stacked structure. Thus, efficient synthetic strategies have been established for the ready preparation of monodisperse polyfluorenes with up to six π-stacked fluorenes, which afford ready access to D-spacer-A triads by linking donor and acceptor groups to the polyfluorene spacers via single methylenes. Detailed 1H NMR spectroscopy, X-ray crystallography, electrochemistry, and He(I) photoelectron spectroscopy of F2-F6 have confirmed the rigid cofacial stacking of multiple fluorenes in F2-F6, despite the presence of rotatable C-C bonds. These polyfluorenes (F2-F6) form stable cation radicals in which a single hole is delocalized amongst the stacked fluorenes, as judged by the presence of intense charge-resonance transition in their optical spectra. Interestingly, these studies also discern that delocalization of a single cationic charge could occur over multiple fluorene rings in F2-F6, while the exciton is likely localized only onto two fluorenes in F2-F6. Facile synthesis of the D-spacer-A triads allowed us to demonstrate that efficient triplet energy transfer can occur through π-stacked polyfluorenes; the mechanism of energy transfer crosses over from tunneling to hopping with increasing number of fluorenes in the polyfluorene spacer. We suggest that the development of rigidly held π-stacked polyfluorenes, described herein, with well-defined redox and optoelectronic properties provides an ideal scaffold for the study of electron and energy transfer in D-spacer-A triads, where the Fn spacers serve as models for cofacially stacked π-systems.

Characterizing the molecular impact of KMT2D variants on the epigenetic and transcriptional landscapes in kabuki syndrome.

Kabuki Syndrome (KS) is a rare, multisystem disorder with a variable clinical phenotype. The majority of KS is caused by dominant loss-of-function mutations in KMT2D (lysine methyltransferase 2D). KMT2D mediates chromatin accessibility by adding methyl groups to lysine residue 4 of histone 3, which plays a critical role in cell differentiation and homeostasis. The molecular underpinnings of KS remain elusive partly due to a lack of histone modification data from human samples. Consequently, we profiled and characterized alterations in histone modification and gene transcription in peripheral blood mononuclear cells (PBMCs) from 33 patients with KMT2D mutations and 36 unaffected healthy controls. Our analysis identified unique enhancer signatures in H3K4me1 and H3K4me2 in KS compared to controls. Reduced enhancer signals were present for promoter-distal sites of immune-related genes for which co-binding of PBMC-specific transcription factors was predicted; thirty-one percent of super-enhancers of normal blood cells overlapped with disrupted enhancers in KS, supporting an association of reduced enhancer activity of immune-related genes with immune deficiency phenotypes. In contrast, increased enhancer signals were observed for promoter-proximal regions of metabolic genes enriched with EGR1 and E2F2 motifs, whose transcriptional levels were significantly increased in KS. Additionally, we identified approximately 100 de novo enhancers in genes, such as in MYO1F and AGAP2. Together, our results underscore the effect of KMT2D haploinsufficiency on dysregulation of enhancer states and gene transcription and provide a framework for the identification of therapeutic targets and biomarkers in preparation for clinical trial readiness.

Providing Quality Work-Based Learning Training for Secondary Family & Consumer Sciences Educators

Families and community members are challenging secondary schools to improve career readiness preparation. Family and consumer sciences (FCS) educators can be instrumental in helping students prepare effectively for a career with school-to-work transitions through work-based learning (WBL). This article presents the implementation of a 2-day FCS educator training designed to guide and build sustainable high-quality WBL experiences for students through a continuum of WBL options.

A polymer library enables the rapid identification of a highly scalable and efficient donor material for organic solar cells.

The dramatic improvement of the PCE (power conversion efficiency) of organic photovoltaic devices in the past few years has been driven by the development of new polymer donor materials and non-fullerene acceptors (NFAs). In the design of such materials synthetic scalability is often not considered, and hence complicated synthetic protocols are typical for high-performing materials. Here we report an approach to readily introduce a variety of solubilizing groups into a benzo[c][1,2,5]thiadiazole acceptor comonomer. This allowed for the ready preparation of a library of eleven donor polymers of varying side chains and comonomers, which facilitated a rapid screening of properties and photovoltaic device performance. Donor FO6-T emerged as the optimal material, exhibiting good solubility in chlorinated and non-chlorinated solvents and achieving 15.4% PCE with L8BO as the acceptor (15.2% with Y6) and good device stability. FO6-T was readily prepared on the gram scale, and synthetic complexity (SC) analysis highlighted FO6-T as an attractive donor polymer for potential large scale applications.

Cu-catalysed enantioselective radical heteroatomic S-O cross-coupling.

The transition-metal-catalysed cross-coupling reaction has established itself as one of the most reliable and practical synthetic tools for the efficient construction of carbon-carbon/heteroatom (p-block elements other than carbon) bonds in both racemic and enantioselective manners. In contrast, development of the corresponding heteroatom-heteroatom cross-couplings has so far remained elusive, probably due to the under-investigated and often challenging heteroatom-heteroatom reductive elimination. Here we demonstrate the use of single-electron reductive elimination as a strategy for developing enantioselective S-O coupling under Cu catalysis, based on both experimental and theoretical results. The reaction manifests its synthetic potential by the ready preparation of challenging chiral alcohols featuring congested stereocentres, the expedient valorization of the biomass-derived feedstock glycerol, and the remarkable catalytic 4,6-desymmetrization of inositol. These results demonstrate the potential of enantioselective radical heteroatomic cross-coupling as a general chiral heteroatom-heteroatom formation strategy.

School Readiness and Community-Based Early Childhood Development (ECD) Centres in Low-Income Communities: Examining The Case of Gugulethu, Western Cape Province, South Africa

A child must be exposed to early learning situations and assisted in developing the skills and ways of functioning to develop, thrive, and be ready for school. It is established that poor school readiness preparation (SRP) negatively impacts subsequent learning outcomes. A qualitative study was conducted in Gugulethu, a poor community in the Western Cape province in South Africa, to determine how Early Childhood Development centres in a poor community prepare children for schooling. The study involved a sample of 12 community-based ECD centres. Interviews and focus group discussions were conducted with direct role-players, including principals, practitioners, and ECD industry key informants. Data was enriched through direct observation of operations at each facility. The study found that all the community-based ECD centres struggle to provide quality SRP. Contributing factors include limited ECD practitioner training, education resources, infrastructure, and facility management. Because these conditions relate to poverty, they affect the SRP of most children in poorer communities, such as Gugulethu, who tend to only have access to under-resourced ECD centres. The study concludes that, given the appalling performance of South Africa’s basic education system, the government has to accept that improving its learning outcomes begins with vastly improving the SRP of children from birth

Towards REDD+ implementation: Deforestation and forest degradation drivers, REDD+ financing, and readiness activities in participant countries

This study provides an assessment of dominant drivers of deforestation and forest degradation across 29 REDD+ participant countries and total funds disbursed from the Forest Carbon Partnership Facility to 15 participant countries since they signed their respective Readiness Preparation Proposals (R-PPs), as well as what they spent the grants on. This study aims to provide information for policymakers and donors on the need to invest in REDD+, as well as the need for participant countries to channel funds to key activities for effectively and efficiently implementing REDD+. The assessment is based on participant countries’ R-PPs and FCPF readiness fund progress reports, using a content analysis approach. The expansion of agriculture, which includes both commercial and subsistence agriculture, was the predominant driver of deforestation, while logging, such as industrial and small-scale exploitation, was the main driver of forest degradation in most participating countries. In addition, we observed that the 15 participant countries received a total of USD 702.36 million for REDD+ readiness preparation. However, most countries have received less than USD 10 million for their readiness-related activities. We observed a huge disparity regarding the funds received between countries from sub-Saharan Africa and their Asian and Latin American counterparts, particularly Indonesia and Peru, respectively. Furthermore, almost all countries have spent their funds on policy and strategy development, stakeholder and consultation events, and public awareness creation. Relatively small amounts have been spent on capacity building and training. Thus, international donors need to focus on strengthening institutional capacities and building effective forest governance structures in countries participating in REDD+, and they should also provide platforms to engage with participant countries to tackle the main deforestation and forest degradation drivers. We suggest further studies to identify high-performing countries that have received lower-than-average funding, consider their deforestation pressures, the size of forests, and the emission reduction potential.

National REDD+ initiatives in Caribbean SIDS to enhance NDC implementation

The objective of this paper is to explore the potential of Reducing Emissions from Deforestation and Forest degradation, and Foster conservation, Sustainable management of forests, and Enhancement of forest carbon stocks (REDD+) to support Caribbean Small Island Developing States (SIDS) efforts in achieving their Nationally Determined Contributions (NDCs) under the 2015 Paris Climate Agreement. A comprehensive overview of the region's perspective on REDD+ in meeting their climate targets in the forestry sector was conducted. The methodology adopted a content analysis of Caribbean countries' NDCs and REDD+ Readiness Preparation Proposals (R-PP). The data used for the content analysis were obtained from initial and updated NDCs for sixteen Caribbean SIDS and REDD+ R-PP for four countries. The results demonstrate that Caribbean countries have high interest in adopting deforestation and forest degradation into their NDC targets. However, REDD+ does not appear to be a high priority in these countries and has been adopted in only four countries. REDD+ systems and mechanisms including measurement, reporting and verification (MRV) in forests, forest and land governance and land rights, and safeguards and financing for REDD+ are hardly considered in Caribbean SIDS NDCs except for the four countries that have already adopted REDD+. These four countries have paid considerable attention to adhere to REDD+ rules as demonstrated in their R-PPs. They are however still in the process of developing MRV forest systems and yet to develop national forest monitoring systems, and details on financing REDD+ and implementation are scarce.

Design, Synthesis, Electronic Properties, and X-ray Structural Characterization of Various Modified Electron-Rich Calixarene Derivatives and Their Conversion to Stable Cation Radical Salts.

We have designed and synthesized electron-rich calixarene derivatives, which undergo reversible electrochemical oxidation in a well-accessible potential range that allows the ready preparation and isolation of the corresponding cation radicals. Preparation of mono- or tetra-radical cation can be achieved by using stable aromatic cation-radical salts such as MA+•, MB+•, and NAP+• as selective organic oxidants. The cation radicals of calixarenes are stable indefinitely at ambient temperatures and can be readily characterized by UV-vis-NIR spectroscopy. These cation radicals bind a single molecule of nitric oxide within its cavity with remarkable efficiency.

Serum Hormone Concentrations and Body Composition in Brazilian Air Force Cadets During Rainforest Survival Training.

Physiological adaptations in military jungle survival training have not yet been studied. Knowledge about the relationship between the insulin-like growth factor type I (IGF-I)/insulin-like growth factor binding protein type 3 (IGFBP-3) system and survival activities in a jungle environment can improve readiness and prepare Brazilian Air Force cadets for this kind of battlefield. Our goal was to assess changes in body composition and serum concentrations of the IGF-I/IGFBP-3 system in Brazilian Air Force cadets during five-day Amazon rainforest survival training and whether differences in sex influence these variations. In the five-day survival training, variations in body composition and serum levels of IGF-I and IGFBP-3 were observed. The sample consisted of 14 male cadets (21.71 ± 1.64 years) and 6 female cadets (22.00 ± 1.41 years). Changes were assessed before and immediately after the survival training. The male cadets' body mass (pre: 73.89 ± 8.79 kg; post: 69.57 ± 8.44 kg), body fat (pre: 11.43 ± 4.15%; post: 10.16 ± 4.19%), IGF-I serum concentrations (pre: 252 ± 72 ng/mL; post: 140 ± 42 ng/mL), and IGFBP-3 serum concentrations (pre: 4.90 ± 0.67 ng/mL; post: 4.22 ± 0.73 ng/mL) were significantly reduced (P < .01). In the female cadets, the mean body mass values (pre: 60.98 ± 8.82 kg; post: 57.91 ± 9.01 kg), body fat (pre: 19.20 ± 5.03%; post: 17.19 ± 4.77%), and IGF-I serum concentrations (pre: 202 ± 50 ng/mL; post: 108 ± 29 ng/mL) also decreased significantly (P < .01) after survival training. Finally, the cadet's sex does not affect the variations of IGF-I (P = .46) and IGFBP-3 (P = .205) serum concentrations. These findings all suggest that changes in body mass and body fat, as well as variations in the IGF-I/IGFBP-3 system, corroborate the need for military readiness preparation. Equivalent changes in both sexes indicate probable equal recovery intervals after survival training.
