A positive stigma for child labor ?
The authors introduce a simple empirical model that assumes a positive stigma (or norm) toward child labor that is common in some developing countries. They illustrate the positive stigma model using data from Guatemala. Controlling for several child and household-level characteristics, the analysis uses two instruments for measuring stigma: a child's indigenous background and the household head's childhood work experience.Street Children,Youth and Governance,Children and Youth,Labor Policies,Primary Education
(3S,4Z)-3-Chloro-1-methyl-4-[(2E)-(3-methylbenzylidene)hydrazinylidene]-3,4-dihydro-1H-2,1-benzothiazine 2,2-dioxide
In the title compound, C17H16ClN3O2S, the dihedral angle between the benzene rings is 7.75 (13)°. The thiazine ring adopts an envelope conformation with the S atom as the flap at a distance of 0.813 (2) Å from the plane through the other five atoms. In the crystal, C—H⋯O hydrogen bonds link the molecules into chains propagating in [100]
6-Bromo-3,3-dichloro-1-methyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide
The monomeric title compound, C9H6BrCl2NO3S, has an envelope-shaped thiazine ring with the S atom 0.879 (9) Å out of the mean square plane of the envelope. The π–π distances between the centroids of the heterocyclic rings are 4.191 (5) and 4.110 (5) Å. The closest intermolecular interactions between the O atoms of the carbonyl and sulfonyl groups with Br and Cl atoms are 2.987 (7) and 2.992 (8) Å, respectively
2-{(E)-[(2Z)-(3-Chloro-1-methyl-2,2-dioxo-3,4-dihydro-1H-2,1-benzothiazin-4-ylidene)hydrazinylidene]methyl}phenol
In the title compound, C16H14ClN3O3S, the thiazine ring adopts a sofa (half-chair) conformation, with an r.m.s. deviation from the mean plane of 0.23 Å. The S atom and S-bonded C atom exhibit the maximum deviations from the thiazine mean plane [−0.3976 (12) and 0.3179 (14) Å, respectively]. The conformations around the double bonds in the R
2C=N—N=CHR unit are Z and E. An intramolecular O—H⋯N hydrogen bond with the hydroxy group as donor generates an S(6) ring motif. In the crystal, pairs of weak C—H⋯O interactions connect the molecules, forming inversion dimers
Methyl 2-[(methylsulfonyl)(propyl)amino]benzoate
The asymmetric unit of the title compound, C12H17NO4S, contains two molecules, both of which show disorder of the two terminal C atoms of the propyl chain over two sets of sites with an occupancy ratio of 0.581 (6):0.419 (6). Intramolecular C—H⋯O interactions help to establish the molecular conformations: in one molecule, the dihedral angle between the methyl ester group and the benzene ring is 41.0 (2)°, whereas in the other molecule it is 36.12 (17)°. In the crystal, molecules are linked by intermolecular C—H⋯O and C—H⋯π interactions
N′-[(E)-1-(5-Chloro-2-hydroxyphenyl)ethylidene]pyridine-3-carbohydrazide monohydrate
In the title compound, C14H12ClN3O2·H2O, the benzene ring and the pyridine rings are oriented at a dihedral angle of 57.73 (12)° and an intramolecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal, the water molecule forms O—H⋯O and O—H⋯N hydrogen bonds to the organic molecule, leading to chains containing R

4(16) loops. In addition, weak aromatic π–π stacking interactions between the centroids of pyridine rings [at distance of 3.864 (2) and 4.013 (2) Å] and C—H⋯π interactions occur
