Alignment of Multi-Tiered Support Systems Following a School-Based Suicide Risk Assessment: Exploring the Lived Experiences of School-Based Mental Health Professionals

The purpose of this study was to explore the experiences of school-based mental health professionals (SBMHP) alignment of multi-tiered systems of support (MTSS) with completed suicide risk assessments (SRA). This qualitative, phenomenological study investigated the experiences of SBMHP with school-based SRA and MTSS. The experiences of SBMHP regarding aligning MTSS with completed SRA prior to this study were unknown. The social ecological model (SEM) provided the framework as it outlines the multiple systems that SBMHP should consider when aligning interventions within a MTSS when working with students, while Joiner’s interpersonal theory of suicide (ITS) provided the grounding for suicidal behavior. Using these theoretical guidelines and the over-arching question, “What are the experiences of SBMHP when aligning MTSS with a completed school-based SRA ,” the research sought to answer: (1) What are the experiences of SBMHP with students’ risk factors when selecting tiered interventions, and (2) What are the experiences of SBMHP with protective factors when conducting SRA? SBMHP who had delivered SRA within five years and informed of multi-tiered interventions were the target population. A purposive sample of SBMHP was interviewed using semi-structured open-ended questions, focus groups, and a reflective journal entry. Transcriptions were coded and analyzed for patterns and recurrent themes. Three themes were evident from the analysis: (1) SRA within an MTSS, (2) Risk and Protective Factors, and (3) Belongingness and the Importance of Connections. This study provided a viewpoint on how to effectively support students with suicidal behavior and recommendations for graduate training. The findings address the lack of research with SRA and MTSS and insights into SBMHP, which can enhance the alignment and implementation of interventions within an MTSS

Relationship between solid state structure and solution stability of copper(ii)-hydroxypyridinecarboxylate complexes

The complementary solid state/solution studies of the systematic series of bioactive ligands 3-hydroxy- 1-methyl-4-pyridinecarboxylate (L1), 3-hydroxy-1,2,6-trimethyl-4-pyridinecarboxylate (L2), 4-hydroxy-1- methyl-3-pyridinecarboxylate (L3), 4-hydroxy-1,6-dimethyl-3-pyridinecarboxylate (L4), 4-hydroxy-1-(2- hydroxyethyl)-6-methyl-3-pyridinecarboxylate (L5) and 4-hydroxy-1-(2-carboxyethyl)-6-methyl-3- pyridinecarboxylate (L6) with copper(II) have been performed in order to design efficient chelating drugs for the treatment of metal overloading conditions. Single crystals of [Cu(L1)2(H2O)]3H2O (1) (monomer) with axial water coordination, [Cu2(L2)4]6H2O (2) and [Cu2(L3)4]4H2O (3) (cyclic dimers), where pyridinolato and carboxylato oxygens, respectively, act as linkers between adjacent copper complexes, [Cu(L4)2]n3H2O (4) (1D polymer) and [Cu3(L5)6]18H2O (5) (trimer), constructed using two square-pyramidal and one elongated octahedral Cu(II) complexes have been determined by SXRD. The bidentate coordination mode of the ligands has been found preferentially with cis arrangements in 1 and 2 and trans arrangements in 3\u20135. The solution speciation and complex stability of aqueous solutions have been studied by pH-dependent electron paramagnetic resonance spectroscopy resulting in the detection of solely monomeric [CuL]+ and [CuL2] complexes. The stability order obtained for the [CuL]+ complexes could be correlated with the deprotonation constants of their hydroxyl group (log bLH) reflecting that the higher acidity increases the complex stability in the order L2 o L1 E L6 o L4 E L5 o L3. This stability order elucidates the different axial linkers in the cyclic dimers 2 and 3. DFT quantum-chemical calculations support the effect of the electron distribution on the established stability order

Simulations of Weighted Tree Automata

Simulations of weighted tree automata (wta) are considered. It is shown how such simulations can be decomposed into simpler functional and dual functional simulations also called forward and backward simulations. In addition, it is shown in several cases (fields, commutative rings, Noetherian semirings, semiring of natural numbers) that all equivalent wta M and N can be joined by a finite chain of simulations. More precisely, in all mentioned cases there exists a single wta that simulates both M and N. Those results immediately yield decidability of equivalence provided that the semiring is finitely (and effectively) presented.Comment: 17 pages, 2 figure

Operadic formulation of topological vertex algebras and Gerstenhaber or Batalin-Vilkovisky algebras

We give the operadic formulation of (weak, strong) topological vertex algebras, which are variants of topological vertex operator algebras studied recently by Lian and Zuckerman. As an application, we obtain a conceptual and geometric construction of the Batalin-Vilkovisky algebraic structure (or the Gerstenhaber algebra structure) on the cohomology of a topological vertex algebra (or of a weak topological vertex algebra) by combining this operadic formulation with a theorem of Getzler (or of Cohen) which formulates Batalin-Vilkovisky algebras (or Gerstenhaber algebras) in terms of the homology of the framed little disk operad (or of the little disk operad).Comment: 42 page

Influence of Arbuscular Mycorrhizal Fungi on Growth and Heavy Metal (Cd & Hg) Uptake of Pinto Peanut (Arachis pintoi)

The pollution of the ecosystem by heavy metals is a real threat to the environment because metals cannot be naturally degraded like organic pollutants and persist in the ecosystem having accumulated in different parts of the food chain. Due to the acute toxicity of heavy metal contaminants, an urgent need to develop low-cost, effective, and sustainable methods to remove or detoxify them from the environment. A study to investigate the growth and heavy metal (Cd and Hg) absorption capacity of Arachis pintoi associated with arbuscular mycorrhizal fungi (AMF) was conducted. The heavy metal (Cadmium and Mercury) uptake of A. pintoi inoculated with arbuscular mycorrizal fungi was also determined and compared by quantifying the heavy metal absorbed by the plants through Atomic Spectrophotometry. Randomized Complete Block Design (RCBD) was used as the experimental design with four treatments replicated three times each for Cadmium and mercury were made. The analysis of variance suggests a highly significant difference in the main effect of treatments, the main effect in weeks and their interaction in cadmium and mercury set-up. The results have found out that Treatment 3 (Heavy metal without AMF) in heavy metal cadmium and mercury has the highest heavy metal uptake. The study further recommend that A. pintoi, a widely available and abundant plant species with mycorrhyzal fungi interaction will be a beneficial procedure in reducing heavy metal pollution in soil

Energy-scales convergence for optimal and robust quantum transport in photosynthetic complexes

Underlying physical principles for the high efficiency of excitation energy transfer in light-harvesting complexes are not fully understood. Notably, the degree of robustness of these systems for transporting energy is not known considering their realistic interactions with vibrational and radiative environments within the surrounding solvent and scaffold proteins. In this work, we employ an efficient technique to estimate energy transfer efficiency of such complex excitonic systems. We observe that the dynamics of the Fenna-Matthews-Olson (FMO) complex leads to optimal and robust energy transport due to a convergence of energy scales among all important internal and external parameters. In particular, we show that the FMO energy transfer efficiency is optimum and stable with respect to the relevant parameters of environmental interactions and Frenkel-exciton Hamiltonian including reorganization energy $\lambda$, bath frequency cutoff $\gamma$, temperature $T$, bath spatial correlations, initial excitations, dissipation rate, trapping rate, disorders, and dipole moments orientations. We identify the ratio of \lambda T/\gamma\*g as a single key parameter governing quantum transport efficiency, where g is the average excitonic energy gap.Comment: minor revisions, removing some figures, 19 pages, 19 figure

Novel technique to extract experimental symmetry free energy information of nuclear matter

A new method of accessing information on the symmetry free energy from yields of fragments produced in Fermi-energy heavy-ion collisions is proposed. Furthermore, by means of quantum fluctuation analysis techniques, correlations between extracted symmetry free-energy coefficients with temperature and density were studied. The obtained results are consistent with those of commonly used isoscaling techniques.Comment: 6 pages, 3 figures Heavy-ion nuclear reactions at Fermi energies, Nuclear equation of State, Fragmentatio
