General attitudes towards marriage scale: psychometric properties in Malaysian adolescents of divorced families

Attitudes towards marriage in adolescence may influence the relationship quality in later years. There exist many measures of attitudes towards marriage which were validated among adolescents from two-parent family in the Western context. There is a need to validate measure of attitudes towards marriage in different countries. This study examined the psychometric properties of the Malay version of general attitudes towards marriage scale in a sample of 480 adolescents from divorced families in Malaysia. Exploratory factor analysis yielded a two-factor structure of general attitudes towards marriage scale, which explained for 60% of the variance. Additionally, the two-factor structure of general attitudes towards marriage scale demonstrated good fit to data in the confirmatory factor analysis (non-normed fit index = .941, comparative fit index = .958, root mean square error of estimation = .087, and χ 2/df = 4.615). Overall, the general attitudes towards marriage scale exhibited good internal consistency (α = .901), which supports the reliability of the instrument. The significant relationships between general attitudes towards marriage scale and other constructs also provided evidences to the convergent validity (r = .761, p < .001 with intent to marry, r = −.170, p < .001 with overt inter-parental conflict, and r = .523, p < .001 with mother–adolescent relationship). Significant gender difference was found in the report of general attitudes towards marriage scale (t = −2.265, p < .05). Thus, the translated general attitudes towards marriage scale is a reliable, valid, and practical instrument to measure attitudes towards marriage among Malaysian adolescents in divorced family setting

Proper-motion age dating of the progeny of Nova Scorpii AD 1437.

'Cataclysmic variables' are binary star systems in which one star of the pair is a white dwarf, and which often generate bright and energetic stellar outbursts. Classical novae are one type of outburst: when the white dwarf accretes enough matter from its companion, the resulting hydrogen-rich atmospheric envelope can host a runaway thermonuclear reaction that generates a rapid brightening. Achieving peak luminosities of up to one million times that of the Sun, all classical novae are recurrent, on timescales of months to millennia. During the century before and after an eruption, the 'novalike' binary systems that give rise to classical novae exhibit high rates of mass transfer to their white dwarfs. Another type of outburst is the dwarf nova: these occur in binaries that have stellar masses and periods indistinguishable from those of novalikes but much lower mass-transfer rates, when accretion-disk instabilities drop matter onto the white dwarfs. The co-existence at the same orbital period of novalike binaries and dwarf novae-which are identical but for their widely varying accretion rates-has been a longstanding puzzle. Here we report the recovery of the binary star underlying the classical nova eruption of 11 March AD 1437 (refs 12, 13), and independently confirm its age by proper-motion dating. We show that, almost 500 years after a classical-nova event, the system exhibited dwarf-nova eruptions. The three other oldest recovered classical novae display nova shells, but lack firm post-eruption ages, and are also dwarf novae at present. We conclude that many old novae become dwarf novae for part of the millennia between successive nova eruptions
