In the title compound, C(9)H(10)FN(3)O, the semicarbazone group is nearly planar, with the maximum deviation of 0.044 (1) Å for one of the N atoms. The mean plane of semicarbazone group forms a dihedral angle of 30.94 (4)° with the benzene ring. The mol-ecules are linked into a supra-molecular chain by N-H⋯O hydrogen bonds formed along the c axis. The crystal structure is further stabilized by ...

Abstract This paper argues that Gareth Matthews’ writing on developmental psychology is both a central part of his philosophical legacy and contribution enduring interest. Although he engages with figures, such as Piaget Kohlberg, who are no longer influential they once were, critique the ‘deficit conception childhood’ retains its relevance today. While deficit model holds any capacity, aptitud...

A reaction of equimolar equivalents 2-naphthaldehyde (1) and 1-(5-methyl-1-(4-nitrophenyl)-1H-1,2,3-triazol-4-yl)ethan-1-one (2) in ethanolic sodium hydroxide at 20 °C for 4 h gave (E)-1-(5-methyl-1-(4-nitrophenyl)-1H-1,2,3-triazol-4-yl)-3-(naphthalen-2-yl)prop-2-en-1-one (3) 92% yield. Nuclear magnetic resonance spectroscopy single-crystal X-ray diffraction were used to establish the structure...

In the title compound, [Cu(C₇H₇N₂O)(C₇H₈N₂O)(H₂O)]ClO₄·H₂O, the Cu(II) ion is five-coordinated by the N atoms from the 1-(pyridin-2-yl)ethanone oximate and 1-(pyridin-2-yl)ethan-one oxime ligands and by the water O atom in a distorted square-pyramidal geometry. The two organic ligands are linked by an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules and ions are linked by O-H⋯O h...

As empirical work in identifying social effects becomes more prevalent, researchers are beginning to struggle with identifying the composition of social interactions within any given reference group. In this paper, we present a simple econometric methodology for the separate identification of multiple social interactions. The setting under which we achieve separation is special, but is likely t...

The stochastic iterated prisoner’s dilemma is a kind of iterated prisoner’s dilemma game where the strategies of the players are specified in terms of cooperation probabilities. In particular, if both players use finitememory strategies, then the game can be modeled by a Markov chain. The purpose of this paper is to discuss several important types of strategies related to such a game, especiall...
