Engaging parents in positive education: Results from a pilot program
Abstract: Positive education aims to contribute to the optimal functioning of students, staff, and school communities. Parents play a vital role in school communities, and finding effective ways to engage parents with positive education is therefore critical. This small-scale pilot study aimed to provide preliminary insights into the impact of a 3-day intensive positive education program for parents, which focused on teaching positive psychology strategies, such as gratitude and use of character strengths, to the parent population. A mixed methodology non-randomized control group design was used to assess pre- to post-intervention change in 24 intervention participants and 16 waitlist control participants. An online survey assessed parentsâ mental health and wellbeing, knowledge and use of character strengths, feelings of connection with the school, and beliefs about child wellbeing. Results revealed significant increases in parental wellbeing and parent-school connection among the intervention participants, as compared to controls. Qualitative results indicated that parents also perceived a positive impact on their communication with their child. Overall, the study findings provide promising preliminary evidence for the benefits of strategically engaging parents in positive education. Replication is now needed in further larger-scale studies.
Ordinary People, Extraordinary Actions
What motivates âordinary peopleâ to support refugees emotionally and financially? This is a timely question considering the number of displaced people in todayâs world is at an all-time high. To help counter this crisis, it is imperative for the Canadian government to determine which policies encourage volunteers to welcome asylum seekers, and which ones must be reviewed. Ordinary People, Extraordinary Actions relates the story of the St. Josephâs Parish Refugee Outreach Committee over its thirty years in action, revealing how seemingly small decisions and actions have led to significant changes in policies and in peopleâs livesâand how they can do so again in the future. By helping readersâyoung and old, secular and faith-orientedâunderstand what drives individuals and communities to welcome refugees with open hearts and open arms, the authors hope to inspire people across Canada and beyond its borders to strengthen our collective willingness and ability to offer refuge as a lifesaving protection for those who need it
The evolution of stable silicon isotopes in a coastal carbonate aquifer on Rottnest Island, Western Australia
Dissolved silicon (dSi) is a key nutrient in the oceans, but data regarding Si isotopes in coastal aquifers are not widely available. Here we investigate the Si isotopic composition of 12 fresh and 16 saline groundwater samples from Rottnest Island, Western Australia, which forms part of the world's most extensive aeolianite deposit (the Tamala Limestone formation). In total, two bedrock samples were also collected from Rottnest Island for Si isotope analysis. The δ30Si values of groundwater samples ranged from â0.4ââ° to +3.6ââ° with an average +1.6ââ°, and the rock samples were â0.8ââ° and â0.1ââ°. The increase in δ30Si values in fresh groundwater is attributed to the removal of the lighter Si isotopes into secondary minerals and potentially also adsorption onto Fe (oxy)hydroxides. The positive correlations between δ30Si values and dSi concentrations (Ďâ=â0.59; pâ=â0.02) and δ30Si values and Cl, but not dSi and Cl concentrations, are consistent with vertical mixing between the younger fresh groundwater and the deeper groundwater, which have undergone a greater degree of waterârock interactions. This has produced a spatial pattern in δ30Si across the aquifer due to the local hydrogeology, resulting in a correlation between δ30Si and tritium activities when considering all groundwater types (Ďâ=ââ0.68; pâ=â0.0002). In the deeper aquifer, the inverse correlation between dSi and Cl concentrations (Ďâ=ââ0.79; pâ=â0.04) for the more saline groundwater is attributed to groundwater mixing with local seawater that is depleted in dSi (<â3.6âÂľM). Our results from this well-constrained island aquifer system demonstrate that stable Si isotopes usefully reflect the degree of waterâaquifer interactions, which is related to groundwater residence time and local hydrogeology. Our finding that lithogenic Si dissolution occurs in the freshwater lens and the freshwaterâseawater transition zone on Rottnest Island appears to supports the recent inclusion of a marineâsubmarine groundwater discharge term in the global dSi mass balance. Geologically young carbonate aquifers, such as Rottnest Island, may be an important source of dSi in coastal regions with low riverine input and low oceanic dSi concentrations
Characterization of the subsurface architecture and identification of potential groundwater paths in a clay-rich floodplain using multi-electrode resistivity imaging
The interaction between surface water and groundwater in clay-rich fluvial environments can be complex and is generally poorly understood. Airborne electromagnetic surveys are often used for characterizing regional groundwater systems, but they are constrained by the resolution of the method. A resistivity imaging survey has been carried out in the Macquarie Marshes (New South Wales, Australia) in combination with water chemical sampling. The results have enabled the identification of buried palaeochannels and the location of potential recharge points. The data have been compared with previously published airborne electromagnetic data in the same area. Deeper less conductive features suggest that there is a potential connection between the Great Artesian Basin and groundwater contained within the shallow sand aquifer. Even though the chemistry of the groundwater samples does not indicate interaction with the Great Artesian Basin, the observed discontinuity in the saprolite implies potential for this to happen in other locations
Risks of introduction and economic consequences associated with African swine fever, classical swine fever and foot-and-mouth disease: A review of the literature
African swine fever (ASF), classical swine fever (CSF) and foot-and-mouth disease (FMD) are considered to be three of the most detrimental animal diseases and are currently foreign to the U.S. Emerging and re-emerging pathogens can have tremendous impacts in terms of livestock morbidity and mortality events, production losses, forced trade restrictions, and costs associated with treatment and control. The United States is the world\u27s top producer of beef for domestic and export use and the world\u27s third-largest producer and consumer of pork and pork products; it has also recently been either the world\u27s largest or second largest exporter of pork and pork products. Understanding the routes of introduction into the United States and the potential economic impact of each pathogen are crucial to (a) allocate resources to prevent routes of introduction that are believed to be more probable, (b) evaluate cost and efficacy of control methods and (c) ensure that protections are enacted to minimize impact to the most vulnerable industries. With two scoping literature reviews, pulled from global data, this study assesses the risk posed by each disease in the event of a viral introduction into the United States and illustrates what is known about the economic costs and losses associated with an outbreak
Emerging biological archives can reveal ecological and climatic change in Antarctica
Anthropogenic climate change is causing observable changes in Antarctica and the Southern Ocean including increased air and ocean temperatures, glacial melt leading to sea-level rise and a reduction in salinity, and changes to freshwater water availability on land. These changes impact local Antarctic ecosystems and the Earth's climate system. The Antarctic has experienced significant past environmental change, including cycles of glaciation over the Quaternary Period (the past similar to 2.6 million years), Understanding Antarctica's paleoecosystems, and the corresponding paleoenvironments and climates that have shaped them, provides insight into present day ecosystem change, and importantly, helps constrain model projections of future change. Biological archives such as extant moss beds and peat profiles, biological proxies in lake and marine sediments, vertebrate animal colonies, and extant terrestrial and benthic marine invertebrates, complement other Antarctic paleoclimate archives by recording the nature and rate of past ecological change, the paleoenvironmental drivers of that change, and constrain current ecosystem and climate models. These archives provide invaluable information about terrestrial ice-free areas, a key location for Antarctic biodiversity, and the continental margin which is important for understanding ice sheet dynamics. Recent significant advances in analytical techniques (e.g., genomics, biogeochemical analyses) have led to new applications and greater power in elucidating the environmental records contained within biological archives. Paleoecological and paleoclimate discoveries derived from biological archives, and integration with existing data from other paleoclimate data sources, will significantly expand our understanding of past, present, and future ecological change, alongside climate change, in a unique, globally significant region
A new conceptual framework for the transformation of groundwater dissolved organic matter
Groundwater comprises 95% of the liquid fresh water on Earth and contains a diverse mix of
dissolved organic matter (DOM) molecules which play a significant role in the global carbon
cycle. Currently, the storage times and degradation pathways of groundwater DOM are
unclear, preventing an accurate estimate of groundwater carbon sources and sinks for global
carbon budgets. Here we reveal the transformations of DOM in aging groundwater using
ultra-high resolution mass spectrometry combined with radiocarbon dating. Long-term
anoxia and a lack of photodegradation leads to the removal of oxidised DOM and a build-up
of both reduced photodegradable formulae and aerobically biolabile formulae with a strong
microbial signal. This contrasts with the degradation pathway of DOM in oxic marine, river,
and lake systems. Our findings suggest that processes such as groundwater extraction and
subterranean groundwater discharge to oceans could result in up to 13 Tg of highly photolabile and aerobically biolabile groundwater dissolved organic carbon released to surface
environments per year, where it can be rapidly degraded. These findings highlight the
importance of considering groundwater DOM in global carbon budgets.Ye
Tracking down carbon inputs underground from an arid zone Australian calcrete.
Freshwater ecosystems play a key role in shaping the global carbon cycle and maintaining the ecological balance that sustains biodiversity worldwide. Surficial water bodies are often interconnected with groundwater, forming a physical continuum, and their interaction has been reported as a crucial driver for organic matter (OM) inputs in groundwater systems. However, despite the growing concerns related to increasing anthropogenic pressure and effects of global change to groundwater environments, our understanding of the dynamics regulating subterranean carbon flows is still sparse. We traced carbon composition and transformations in an arid zone calcrete aquifer using a novel multidisciplinary approach that combined isotopic analyses of dissolved organic carbon (DOC) and inorganic carbon (DIC) (δ13CDOC, δ13CDIC, 14CDOC and 14CDIC) with fluorescence spectroscopy (Chromophoric Dissolved OM (CDOM) characterisation) and metabarcoding analyses (taxonomic and functional genomics on bacterial 16S rRNA). To compare dynamics linked to potential aquifer recharge processes, water samples were collected from two boreholes under contrasting rainfall: low rainfall ((LR), dry season) and high rainfall ((HR), wet season). Our isotopic results indicate limited changes and dominance of modern terrestrial carbon in the upper part (northeast) of the bore field, but correlation between HR and increased old and 13C-enriched DOC in the lower area (southwest). CDOM results show a shift from terrestrially to microbially derived compounds after rainfall in the same lower field bore, which was also sampled for microbial genetics. Functional genomic results showed increased genes coding for degradative pathways-dominated by those related to aromatic compound metabolisms-during HR. Our results indicate that rainfall leads to different responses in different parts of the bore field, with an increase in old carbon sources and microbial processing in the lower part of the field. We hypothesise that this may be due to increasing salinity, either due to mobilisation of Cl- from the soil, or infiltration from the downstream salt lake during HR. This study is the first to use a multi-technique assessment using stable and radioactive isotopes together with functional genomics to probe the principal organic biogeochemical pathways regulating an arid zone calcrete system. Further investigations involving extensive sampling from diverse groundwater ecosystems will allow better understanding of the microbiological pathways sustaining the ecological functioning of subterranean biota
XAF1 as a modifier of p53 function and cancer susceptibility
Cancer risk is highly variable in carriers of the common TP53-R337H founder allele, possibly due to the influence of modifier genes. Whole-genome sequencing identified a variant in the tumor suppressor XAF1 (E134*/Glu134Ter/rs146752602) in a subset of R337H carriers. Haplotype-defining variants were verified in 203 patients with cancer, 582 relatives, and 42,438 newborns. The compound mutant haplotype was enriched in patients with cancer, conferring risk for sarcoma (P = 0.003) and subsequent malignancies (P = 0.006). Functional analyses demonstrated that wild-type XAF1 enhances transactivation of wild-type and hypomorphic TP53 variants, whereas XAF1-E134* is markedly attenuated in this activity. We propose that cosegregation of XAF1-E134* and TP53-R337H mutations leads to a more aggressive cancer phenotype than TP53-R337H alone, with implications for genetic counseling and clinical management of hypomorphic TP53 mutant carriers.Fil: Pinto, Emilia M..
