Morir y volver a nacer: el cuerpo masculino entre la tortura y la victoria épica en el cine político argentino de los 70

Este trabajo pretende analizar las escenas vinculadas a la tortura, en dos filmes del denominado Cine Político producido en la década del 70 en Argentina: Los Traidores de Raymundo Gleyzer y Los hijos de Fierro de Fernando ?Pino? Solanas. Corriéndonos de cualquier interpretación que entienda dichas escenas como meras denuncias a las prácticas represivas por parte del Estado de la época, nos proponemos descifrar y valorar dichas escenas en relación a la trama romántica que organiza los sucesos en ambos filmes. En la trama romántica propuesta por ambas películas se narran las luchas populares en pos del cambio social, forjándose representaciones masculinas vinculadas al trabajo y la militancia cuya virilidad es puesta a prueba explícita o implícitamente por las escenas de torturas. El presente artículo complementa dicho análisis con un acercamiento al problema de la recepción y la vinculación entre figura masculina y espectador modelo.Fil: Navone, Santiago.

Models of cuspy triaxial stellar systems. II. Regular orbits

In the first paper of this series we used the N--body method to build a dozen cuspy (gamma ~ 1) triaxial models of stellar systems, and we showed that they were highly stable over time intervals of the order of a Hubble time, even though they had very large fractions of chaotic orbits (more than 85 per cent in some cases). The models were grouped in four sets, each one comprising models morphologically resembling E2, E3, E4 and E5 galaxies, respectively. The three models within each set, although different, had the same global properties and were statistically equivalent. In the present paper we use frequency analysis to classify the regular orbits of those models. The bulk of those orbits are short axis tubes (SATs), with a significant fraction of long axis tubes (LATs) in the E2 models that decreases in the E3 and E4 models to become negligibly small in the E5 models. Most of the LATs in the E2 and E3 models are outer LATs, but the situation reverses in the E4 and E5 models where the few LATs are mainly inner LATs. As could be expected for cuspy models, most of the boxes are resonant orbits, i.e., boxlets. Nevertheless, only the (x, y) fishes of models E3 and E4 amount to about 10 per cent of the regular orbits, with most of the fractions of the other boxlets being of the order of 1 per cent or less.Comment: Accepted for publication in the Monthly Notices of the Royal Astronomical Societ

Models of cuspy triaxial stellar systems. III: The effect of velocity anisotropy on chaoticity

In several previous investigations we presented models of triaxial stellar systems, both cuspy and non cuspy, that were highly stable and harboured large fractions of chaotic orbits. All our models had been obtained through cold collapses of initially spherical $N$--body systems, a method that necessarily results in models with strongly radial velocity distributions. Here we investigate a different method that was reported to yield cuspy triaxial models with virtually no chaos. We show that such result was probably due to the use of an inadequate chaos detection technique and that, in fact, models with significant fractions of chaotic orbits result also from that method. Besides, starting with one of the models from the first paper in this series, we obtained three different models by rendering its velocity distribution much less radially biased (i.e., more isotropic) and by modifying its axial ratios through adiabatic compression. All three models yielded much higher fractions of regular orbits than most of those from our previous work. We conclude that it is possible to obtain stable cuspy triaxial models of stellar systems whose velocity distribution is more isotropic than that of the models obtained from cold collapses. Those models still harbour large fractions of chaotic orbits and, although it is difficult to compare the results from different models, we can tentatively conclude that chaoticity is reduced by velocity isotropy.Comment: 11 pages, 14 figures.

Investors' distraction and strategic repricing decisions

In this paper I analyze investors' reactions to changes in the expense ratios of equity mutual funds. I show that investment flows' response to fees cannot be fully explained by looking at investors' performance sensitivity. While performance sensitivity monotonically increases with past performance, price sensitivity does not: investors who buy top past performers seem to be "distracted" by the fund's previous return and pay relatively little attention to the expense ratios. Moreover price sensitivity increases with fund visibility while performance sensitivity decreases, and while looking at data from 1986 to 2006 no discernible trend can be observed in the average performance sensitivity, price sensitivity strongly increases due to the dramatic increase in the availability of mutual funds' information for retail investors. Finally I show that investment companies strategically time their repricing decisions in order to exploit time variations in price and performance sensitivities, and that fund governance quality affects the degree to which investment companies engage in this opportunistic behavior

The Grace and Call of the Hospitable God

John Navone explains how human hospitality “images the tri-personal God of Christians who is love.” He also discusses how Jesus’s parables invite us to participate in God’s hospitality and call us to be hospitable to others. Beauty is an important part of God’s hospitality because it is the aspect of the good that attracts us. Three moments of divine and human hospitality in salvation history are identified; in each, the human hosts meet God in the form of a stranger or strangers. Since the hospitality is freely given, it is reflective of grace and of our creation. We are given life out of “God sharing his bounty,” and therefore we must be generous. As Navone describes it, hospitality in the City of God “demand[s] a profound conversion of the heart and a conscious commitment to the quest for the common good.” Scriptural passages on hospitality are included

Cloning and expression of a human kinesin heavy chain gene: interaction of the COOH-terminal domain with cytoplasmic microtubules in transfected CV-1 cells.

To understand the interactions between the microtubule-based motor protein kinesin and intracellular components, we have expressed the kinesin heavy chain and its different domains in CV-1 monkey kidney epithelial cells and examined their distributions by immunofluorescence microscopy. For this study, we cloned and sequenced cDNAs encoding a kinesin heavy chain from a human placental library. The human kinesin heavy chain exhibits a high level of sequence identity to the previously cloned invertebrate kinesin heavy chains; homologies between the COOH-terminal domain of human and invertebrate kinesins and the nonmotor domain of the Aspergillus kinesin-like protein bimC were also found. The gene encoding the human kinesin heavy chain also contains a small upstream open reading frame in a G-C rich 5' untranslated region, features that are associated with translational regulation in certain mRNAs. After transient expression in CV-1 cells, the kinesin heavy chain showed both a diffuse distribution and a filamentous staining pattern that coaligned with microtubules but not vimentin intermediate filaments. Altering the number and distribution of microtubules with taxol or nocodazole produced corresponding changes in the localization of the expressed kinesin heavy chain. The expressed NH2-terminal motor and the COOH-terminal tail domains, but not the alpha-helical coiled coil rod domain, also colocalized with microtubules. The finding that both the kinesin motor and tail domains can interact with cytoplasmic microtubules raises the possibility that kinesin could crossbridge and induce sliding between microtubules under certain circumstances

Firm Opacity Lies in the Eye of the Beholder

We classify and test empirical measures of firm opacity and document theoretical and empirical inconsistencies across these proxies by testing the relative opacity of banks versus non-banks. We evaluate the effectiveness of these proxies by observing the effect of two cleanly identified shocks to firm-specific information: credit rating initiation and inclusion in the S&P 500 index. Using a difference-in-difference approach, we compare firms that are newly rated and firms that are included in the S&P 500 index with a propensity matched sample of “unchanged” firms. We find that only the number of analysts and Amihud's illiquidity ratio provide consistent patterns across different estimation specifications and different econometric settings. These two proxies show that banks are more opaque than non-banks. Based on our tests, we recommend that these proxies be used as the primary measures of firm opacity
