Repeating the Errors of Our Parents? Family-of-Origin Spouse Violence and Observed Conflict Management in Engaged Couples

Based on a developmental social learning analysis, it was hypothesized that observing parental violence predisposes partners to difficulties in managing couple conflict. Seventy-one engaged couples were assessed on their observation of parental violence in their family of origin. All couples were videotaped discussing two areas of current relationship conflict, and their cognitions during the interactions were assessed using a video-mediated recall procedure. Couples in which the male partner reported observing parental violence (male-exposed couples) showed more negative affect and communication during conflict discussions than couples in which neither partner reported observing parental violence (unexposed couples). Couples in which only the female partner reported observing parental violence (female- exposed couples) did not differ from unexposed couples in their affect or behavior. Female-exposed couples reported more negative cognitions than unexposed couples, but male-exposed couples did not differ from unexposed couples in their reported cognitions

Effect of mean void fraction correlations on a shell-and-tube evaporator dynamic model performance

In this paper, the influence of different mean void fraction correlations on a shell-and-tube evaporator dynamic model performance has been evaluated. The model proposed is based on the moving boundary approach and includes the expansion valve modelling. Several transient tests, using R134a as working fluid, have been carried out varying refrigerant mass flow, inlet enthalpy and secondary fluid flow. Then, the model performance, using different mean void fractions, is analysed from the system model outputs (evaporating pressure, refrigerant outlet temperature and condensing water outlet temperature). The slip ratio expressions selected are: homogenous, momentum flux model, Zivi's, Chisholm's and Smith's correlations. The results of the comparison between experimental and model predictions depend on the transient characteristics and there is not a single slip ratio correlation that provides the best performance in all the cases analysed.Navarro-Esbrí, J.; Milián Sánchez, V.; Mota Babiloni, A.; Molés Ribera, F.; Verdú Martín, GJ.

Dynamic analysis of repetitive decision-free discreteevent processes: The algebra of timed marked graphs and algorithmic issues

A model to analyze certain classes of discrete event dynamic systems is presented. Previous research on timed marked graphs is reviewed and extended. This model is useful to analyze asynchronous and repetitive production processes. In particular, applications to certain classes of flexible manufacturing systems are provided in a companion paper. Here, an algebraic representation of timed marked graphs in terms of reccurrence equations is provided. These equations are linear in a nonconventional algebra, that is described. Also, an algorithm to properly characterize the periodic behavior of repetitive production processes is descrbed. This model extends the concepts from PERT/CPM analysis to repetitive production processes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44155/1/10479_2005_Article_BF02248590.pd

Todas as criaturas do mundo: a arte dos mapas como elemento de orientação geográfica

Vague in the outlines and abounding in figures of real or fabulous creatures, the iconography of medieval maps played a significant role in helping users to recognize lands that were virtually unknown to Christendom. In a world with no reliable latitudes and longitudes, the land contours, inhabitants and even certain elements of fauna and flora could become variables of utmost importance for geographic orientation. Notwithstanding the higher levels of precision achieved in their efforts to represent geographic space, the considerable advancements made in latitude determination, and their continuous pursuit of a practical method for the establishment of longitudes, the cartographers of the Age of Discoveries still went to the trouble of depicting notable elements - whether real or imaginary - to help travelers get their bearings around different regions of the globe. As the presence of Europeans continued to expand and an authentic scientific revolution took place in the 17th century, the lengthy notes and eye¿catching representations of nature and local inhabitants soon lost their utility as points of reference on 17th-century maps to become mere accessories of aesthetic and commercial value. The advent of the 18th century consolidated, once and for all, the transformation of such illustrations into essentially decorative elements with no other relevant role to play in mapmaking. In addition to decreasing in number, the figures became more stylized and moved to the borders of the maps as ornamental motifs. Although they often maintained some sort of relation with the geographic space depicted on the map, the motifs chosen could also constitute a rather independent element. In fact, allegories, compositions with a variety of mythological figures, and historical representations were often used to underscore the power of certain political agents

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.
