Control and cost accounting practices in the Spanish Royal Tobacco Factory

Abstract: The aim of this paper is to analyse the cost accounting system implemented in 1773 by a large, state owned, tobacco factory in Spain (the Royal Tobacco Factory, RTF) which operated as a monopolist. Drawing on data extracted from original archives, the paper examines the characteristics of the cost system within the broader context of a strict control system. One of the main roles of the cost accounting system was to buttress a set of structural measures instituted in the RTF with the aim of minimising the scope for tobacco theft. Another aim was to impart visibility upon the various activities undertaken in the RTF. The paper also examines the role of the cost accounting practices as a disciplinary regime. A combination of physical measures, reflecting the rates and mixes of resource utilization and monetary measures were developed to facilitate monitoring and surveillance of the activities of the factory employees. These measures were used to establish a powerful regime of calculation which rendered human accountability visible. Such emphasis upon calculation created an environment at the RTF in which management could compare, differentiate, hierarchize, homogenize, and even exclude individuals.

hpttg, a human homologue of rat pttg, is overexpressed in hematopoietic neoplasms. Evidence for a transcriptional activation function of hPTTG.

Abstract: We have isolated a human cDNA clone encoding a novel protein of 22 kDa that is a human counterpart of the rat oncoprotein PTTG. We show that the corresponding gene (hpttg) is overexpressed in Jurkat cells (a human T lymphoma cell line) and in samples from patients with different kinds of hematopoietic malignancies. Analysis of the sequence showed that hPTTG has an amino-terminal basic domain and a carboxyl-terminal acidic domain, and that it is a proline-rich protein with several putative SH3-binding sites. Subcellular fractionation studies show that, although hPTTG is mainly a cytosolic protein, it is partially localized in the nucleus. In addition we demonstrate that the acidic carboxyl-terminal region of hPTTG acts as a transactivation domain when fused to a heterologous DNA binding domain, both in yeast and in mammalian cells.

New Evidence on Breastfeeding and Postpartum Depression: The Importance of Understanding Women's Intentions

Abstract: This study aimed to identify the causal effect of breastfeeding on postpartum depression (PPD), using data on mothers from a British survey, the Avon Longitudinal Study of Parents and Children. Multivariate linear and logistic regressions were performed to investigate the effects of breastfeeding on mothers’ mental health measured at 8 weeks, 8, 21 and 32 months postpartum. The estimated effect of breastfeeding on PPD differed according to whether women had planned to breastfeed their babies, and by whether they had shown signs of depression during pregnancy. For mothers who were not depressed during pregnancy, the lowest risk of PPD was found among women who had planned to breastfeed, and who had actually breastfed their babies, while the highest risk was found among women who had planned to breastfeed and had not gone on to breastfeed. We conclude that the effect of breastfeeding on maternal depression is extremely heterogeneous, being mediated both by breastfeeding intentions during pregnancy and by mothers’ mental health during pregnancy. Our results underline the importance of providing expert breastfeeding support to women who want to breastfeed; but also, of providing compassionate support for women who had intended to breastfeed, but who find themselves unable to.

A Unified Analysis of the Fault Tolerance Capability in Six-Phase Induction Motor Drives

Abstract: The fault tolerance of electric drives is highly appreciated at industry for security and economic reasons, and the inherent redundancy of six-phase machines provides the desired fault-tolerant capability with no extra hardware. For this reason some recent research efforts have been focused on the fault-tolerant design, modeling, and control of six-phase machines. Nevertheless, a unified and conclusive analysis of the postfault capability of six-phase machine is still missing. This paper provides a full picture of the postfault derating in generic six-phase machines and a specific analysis of the fault-tolerant capability of the three mainstream six-phase induction machines (asymmetrical, symmetrical, and dual three phase). Experimental results confirm the theoretical post fault current limits and allow concluding, which is the best six-phase machine for each fault scenario and neutral arrangement.

Conocimiento profesional y epistemología de los profesores I: teoría, métodos e instrumentos

Abstract: We present in this article the theoretic and methodological frame of the studies carried out by the authors on teacher’s professional knowledge and epistemological conceptions, taking as a reference the bases of the Model of Investigation at the School and the IRES curricular project. In a latter article we will analyse the data there obtained.
