Development and validation of Vietnam teachers' resilience scale instrument: A four-factor model.

Existing studies on resilience measures tailored explicitly to teachers are relatively scarce, and the development of teacher resilience scales in developing Asian nations is lacking. To address this gap, we developed the Vietnam Teachers' Resilience Scale (VITRS), drawing on the Teachers' Resilience Scale (Daniilidou & Platsidou, 2018) and the Multidimensional Teachers' Resilience Scale (Mansfield & Wosnitza, 2015; Peixoto et al., 2020). The VITRS comprises 20 items across four dimensions (Social, Professional, Emotional, and Motivational resilience), demonstrating psychometric properties. The VITRS exhibits high reliability and validity and can serve as a significant assessment tool for high school and university teachers. This enables them to measure their resilience and prepare effectively to face and adapt to adversity. Despite these limitations, this study opens new avenues for future research.

Green synthesis and crystal structure of 3-(benzo-thia-zol-2-yl)thio-phene.

The title compound, C11H7NS2, was prepared in high yield (87%) using a solvent-free microwave-assisted synthesis. The structure shows whole-mol-ecule disorder with occupancies for two orientations (A and B) of 0.4884 (10) and 0.5116 (10), respectively. The thio-phene and benzo-thia-zole rings are almost planar and make dihedral angles of 10.02 (18) and 12.54 (19)° for orientations A and B, respectively. Slipped π-π stacking between the aromatic rings, together with C-H⋯π, C-H⋯S and C-H⋯N inter-actions, result in a herringbone motif in the crystal packing.

Crystal structure of 4-amino-3-(thio-phen-3-ylmeth-yl)-1H-1,2,4-triazole-5(4H)-thione.

In the title compound, C7H8N4S2, the thio-phene ring shows rotational disorder over two orientations in a 0.6957 (15):0.3043 (15) ratio. The plane of the 1,2,4-triazole ring makes a dihedral angle of 75.02 (17)° with the major-disorder component of the thiophene ring. In the crystal, two types of inversion dimers, described by the graph-set motifs R22(8) and R22(10), are formed by N-H⋯S inter-actions. Chains of mol-ecules running in the [101] direction are linked by weaker N-H⋯N inter-actions. The thio-phene ring is involved in π-π and C-H⋯π inter-actions.

Crystal structure of N-(4-oxo-2-sulfanyl-idene-1,3-thia-zolidin-3-yl)-2-(thio-phen-3-yl)acetamide.

The title compound, C9H8N2O2S3, crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209 Å) and are linked by an N-H⋯O hydrogen bond. In both mol-ecules, the thio-phene rings show orientational disorder, with occupancy factors of 0.6727 (17) and 0.3273 (17) for mol-ecule A, and 0.7916 (19) and 0.2084 (19) for mol-ecule B. The five-membered rings make an angle of 79.7 (2)° in mol-ecule A and an angle of 66.8 (2)° in mol-ecule B. In the crystal, chains of mol-ecules running along the a-axis direction are linked by N-H⋯O hydrogen bonds. The inter-action of adjacent chains through N-H⋯O hydrogen bonds leads to two types of ring structures containing four mol-ecules and described by the graph-set motifs R44(18) and R42(14).

Bipodal acylthiourea ligands as building blocks for Bi-, tetra-, and polynuclear oxorhenium(V) complexes.

Reactions of (NBu4)[ReOCl4] and 3,3,3',3'-tetraalkyl-1,1'-isophthaloylbis(thioureas), H2phth(R2tu)2 where R = Et, i-Bu, in hot MeOH with the addition of Et3N give red products of the composition [ReO(OMe){phth(R2tu)2}]2 (8a, R = Et; 8b, R = i-Bu). X-ray structures of 8 reveal symmetric binuclear complexes containing two almost coplanar organic ligands, each of which coordinates to two rhenium centers via the two bidentate-O,S moieties. The octahedral coordination spheres of the rhenium atoms are completed by each one oxo and one methoxido ligand which are directed perpendicular to the plane defined by the {phth(R2tu)2}(2-) ligands. While in 8a, both methoxido ligands point to the same side of the described plane and form a syn isomer, the MeO(-) ligands in 8b are located at opposite sides and form an anti isomer. Studies in solution show that there exists a reversible equilibrium between the anti and syn isomers. Dimerization/condensation of complexes 8 with the formation of tetranuclear complexes of the composition [{ReO{phth(R2tu)2}}2O]2 (9) and/or polynuclear species is observed in solutions, which do not contain MeOH.
