Interview In pursuit of communication An interview with

There was a time when all science was carried out with brain and hands. Far from huge investments and large organizations, people would build up equipment, manipulate animals and do experiments. The process took place on a single-individual scale. This prompted people to think that they were able to emulate scientists and to develop the drive to become a scientist. Science is still an individual issue, but it is also true that today, it is more heavily dependent on complex technology, organization and managing structures than it was 50 years ago. No regret, this is merely descriptive. Indeed, modern science becomes more and more a labor of teams, in which the individual becomes an integral part. There is also a tradition in life sciences in which basic biology attracts physicians to research. They want to know in order to cure, of course, but many get more involved due to their interest in knowledge and many even become basic scientists. So they walk far away from the immediacy of so-called “applied research” and similar euphemisms and dedicate their professional lives to scientific research. Not forgetting that they want to cure disease and alleviate suffering, they become firm supporters of the benefits of basic science. These two ideas are perhaps incarnated in Robert J. Ruben, a born New Yorker who won a scientific prize while at high school for breeding at home a mutant mouse with audiogenic seizures. He obtained his undergraduate degree from Princeton University in 1955 and went on to study medicine at the Johns Hopkins School of Medicine. He then did his post graduate medical training at the Johns Hopkins Hospital, spent two years Int. J. Dev. Biol. 51: 439-445 (2007) doi: 10.1387/ijdb.072379fg
Mating Behavior in Three Species of the Drosophila hypocausta SubgrouplBehavior Biologyr

Courtship behavior was evaluated to investigate the degree of sexual isolation in three related species, Drosophila hypocausta, D. neohypocausta and D. siamana. Patterns of male courtship behavior and the nature of courtship sounds using an oscilloscope were compared among these species. D. siamana was ethologically isolated incompletely from D. hypocausta; D. siamana females were highly receptive to D. hypocausta males, giving the average rate of insemination of 67.1%, although the reciprocal crosses gave only 13.4%. The nature of the courtship behavior and courtship sounds emitted by males showed species-specific patterns. Results of crossability tests and behavioral analyses suggested that D. siamana is a good species of the D. hypocausta subgroup of the D. immigrans species group.

AN ASYMMETRIC JET-LAUNCHING MODEL FOR THE PROTOPLANETARY NEBULA CRL 618

We propose an asymmetrical jet-ejection mechanism in order to model the mirror symmetry observed in the lobe distribution of some protoplanetary nebulae (pPNs), such as the pPN CRL 618. Three-dimensional hydrodynamical simulations of a precessing jet launched from an orbiting source were carried out, including an alternation in the ejections of the two outflow lobes, depending on which side of the precessing accretion disk is hit by the accretion column from a Roche lobe-filling binary companion. Both synthetic optical emission maps and position–velocity diagrams were obtained from the numerical results with the purpose of carrying out a direct comparison with observations. Depending on the observer's point of view, multipolar morphologies are obtained that exhibit a mirror symmetry at large distances from the central source. The obtained lobe sizes and their spatial distributions are in good agreement with the observed morphology of the pPN CRL 618. We also obtain that the kinematic ages of the fingers are similar to those obtained in the observations.
Capacité de mémoire dans le modèle de Hopfield

Nous considerons le modele de Hopfield de memoire associative [2]. Designons par N le nombre de neurones et par m celui de prototypes.

Isolation and characterization of residual lignins in kraft pulps

Des lignines residuelles ont ete isolees de diverses pâtes kraft de resineux a l'aide d'un procede discontinu d'acidolyse des dioxanes et de reacteurs a circulation directe. Les lignines ont ete par la suite caracterisees a l'aide de diverses techniques spectroscopiques et de traitements chimiques par voie humide. Nous avons trouve que les lignines isolees a l'aide du reacteur etaient composees d'elements et de groupements fonctionnels similaires, comparativement aux lignines de l'acidolyse obtenues a partir des memes pâtes a l'aide du procede discontinu. Les donnees obtenues viennent confirmer l'hypothese que la structure de la lignine residuelle dans les pâtes kraft n'est pas modifiee de facon significative pendant le procede d'isolation de l'acidolyse des dioxanes. Nous avons aussi decouvert que lors de la cuisson kraft classique, parmi les changements structurels majeurs survenant dans la lignine residuelle, on trouve l'enrichissement graduel des acides carboxyliques et des groupements d'hydroxyles phenoliques condenses. Vers la fin de la cuisson, kraft, la lignine residuelle contient trois fois plus de groupements hydroxyles phenoliques condenses C 5 que ceux presents dans l'echantillon de bois de depart. Nous avons trouve que les unites hydroxyles phenoliques condensees C 5 et C 6 etaient toutes deux relativement stables pour la delignification a l'oxygene. Ces resultats viennent confirmer la notion que la teneur plus elevee en unites condensees de la lignine residuelle est partiellement responsable de la resistance accrue de cette lignine a une delignification plus poussee. Une comparaison de la structure de la lignine residuelle d'une pâte kraft classique avec une structure produite selon un protocole modifie (EMCC) a demontre que cette derniere contenait une quantite moindre de phenoliques condenses et une quantite plus elevee d'acides carboxyliques et d'unite phenoliques non condensees. Ces differences confirment que les procedes de cuisson modifies modernes sont plus efficaces en matiere de delignification que leurs contreparties classiques. Il a aussi ete demontre que les pâtes kraft de pruche sont en general plus difficiles a blanchir que les pâtes kraft d'epinette.
Geology, petrology and geochemistry of the dome complex of Huequi volcano, southern Chile.

El volcan Huequi es poco conocido, que se ubica en la provincia sur de la zona Volcanica Sur de los Andes (ZVSS). Sus tipos de erupcion y caracteristicas mineralogicas y geoquimicas son poco comunes a nivel regional. El volcan presenta multiples domos poco erosionados. Las erupciones estuvieron acompanadas por una actividad explosiva secundaria, siendo las mas recientes las ocurridas entre los anos 1890 y 1920. Los magmas del Huequi son de composicion andesitico-basaltica a dacitica. Si se las compara con rocas eruptadas por otros centros volcanicos de la ZVSS de los Andes, las del Huequi se caracterizan por ser pobres en K, ricas en Al y por presentar fenocristales euhedrales de anfibola. Las composiciones totales sugieren una fuente magmatica rica en H2O, que se desarrolla a traves de niveles de cristalizacion fraccionada y desgasificacion subsecuente, que producen domos volcanicos andesiticos altamente porfiricos. Sin embargo, la causa ultima que genera magmas ricos en H2O, en esta parte de los Andes, sigue aun sin explicacion.
Title of Paper : Do finance constraints affect inventory investment decisions of firms ? Evidence for the Portuguese manufacturing sector

In recent years there has been an increasing debate on the determinants of a firm’s investment decisions. In fact, according to the investment models that assume perfect capital markets (e.g. Q-Tobin model), the availability of internal funds does not affect investment decisions. Investment outlays in each period are determined in perfectly functioning capital markets. Financial factors are only considered in the cost of capital, which, in turn, is independent of the way in which a firm finances itself (Bond and Meghir, 1994). On the other hand, the finance constraints model rejects the independence between investment and finance decisions of a firm due to problems of asymmetric information in financial markets. In fact, this model assumes that the participants in financial markets do not share the same information. For example, managers of a particular firm have better information on its future perspectives than potential lenders. As consequence, there is no perfect substitution between a firm’s internal and external funds, and this leads to a hierarchy of finance (Myers, 1984), where the cost of internal funds becomes cheaper than the cost of external funds. Therefore, the finance constraints model concludes that the financial status of a firm is a determinant of its investment decisions. The aim of this paper is to analyse the existence of finance constraints on inventory investment decisions of Portuguese manufacturing firms. To test this impact, a modified version of Lovell’s model (1961) was used. The model was extended to include financial variables that are a proxy to the financial position of a firm. The data used related to the period between 1990 and 2000, and was split into subsamples based on size, age, and interest coverage ratio to reflect expected differences in the degrees of asymmetric information problems. Furthermore, an econometric inventory investment equation was estimated for each group of firms. The results of this study showed that, as the finance constraints hypothesis indicates, financial variables have a greater impact on inventory investment decisions of firms that are more subject to information problems in financial markets (e.g., small and young),.
Testing dynamical vacuum models with CMB power spectrum from Planck

The cosmic expansion is computed for various dynamical vacuum models $\Lambda(H)$ and confronted to the Cosmic Microwave Background (CMB) power spectrum from Planck. We also combined CMB in a joint analysis with other probes in order to place constraints on the cosmological parameters of the dynamical vacuum models. We find that all $\Lambda(H)$ models are very efficient and in very good agreement with the data. Considering that the interaction term of the dark sector is given in terms of matter and radiation densities, we find that the corresponding $\Lambda(H)$ model shows a small but non-zero deviation from $\Lambda$ cosmology, nevertheless the confidence level is close to $\sim 2.4\sigma$.

Complex acylation of Angiotensin II by N-Hydroxysulfosuccinimide linked biotin reagents

N-Hydroxysulfosuccinimide-linked biotins (sulfoNHS-biotins) are water soluble biotin tags commonly used to conjugate a biotin moiety to proteins by rapid N-acylation of primary amines. Unexpected O-acylation by sulfoNHSbiotin on tyrosine of Angiotensin II (Ag-II) and an acylation on third site unable to characterize were identified by LC-MS in addition to the expected N-acylation on the N-terminal of Ag-II. The N-acylation only undergoes incomplete hydrolysis in 0.1% formic acid not at pH 7.2 and 8.0, while two unexpected acylation hydrolyze at both conditions, but their hydrolysis in 0.1% formic acid was much more rapid. Dithiothreitol treatment selectively catalyzed hydrolysis of both of the unexpected acylation but not the N-acylation of Ag-II. The maximum yield of O-acylation of the Ag- II tyrosine was 99% at pH 7.2 and 95% at pH 8.0 as compared N-acylation of lysine when reacted with excess sulfoNHS-biotin with these yields of 94% at pH 7.2 and 96% at pH 8.0. Acylation of the third uncharacterized site of Ag-II showed maximum yield of approximately 17% at pH 7.2, but higher yield (≥ 47%) at pH 8.0 within 30 min. The unexpected O-acylation of the Ag-II tyrosine occurred within 1 min at either pH 7.2 or pH 8.0, as rapidly as the N-acylation, while the other unexpected acylation required more time to complete at pH 8.0.
Prevention of Hearing Disorders: Neonatal Causes of Hearing Loss

Reprint requests: Dr. Wilkening, Section of Neonatology, University of Colorado Health Sciences Center, 4200 East Ninth Avenue, Denver, CO 80267. Prompted by research findings in the late 1970s and early 1980s and incidence figures for moderate to profound hearing loss of 2 to 5 percent among high-risk infants, the American Academy of Pediatrics published a position statement from the Joint Committee on Hearing in 1982. Seven risk criteria were given for identifying infants at risk for hearing loss (see Table 1). Recommendations were made for screening such infants by 3 to 6 months of age without specifying any particular screening device. Guidelines for habilitation services were also given. Since 1982, a number of studies have been published that demonstrate the incidence of moderate to profound hearing loss to be 2 to 10 percent in graduates of intensive care nurseries (ICN). Within certain high-risk groups of ICN graduates, the incidence is even higher. In this article we focus on the neonatal causes of hearing loss, especially those among ICN graduates. The seven risk criteria given by the Joint Committee on Infant Hearing will be addressed. Additional concerns among specific groups of newborns also will be discussed.
Student evaluation of their learning: differences in male and female students' perception of their units

This paper reports an investigation into differences between undergraduate male and female students’ perceptions of their learning using eVALUate, an online unit evaluation survey. The sample included unit survey feedback from all semesters from Semester 1 2006 onwards. Aggregated percentage agreement was calculated for each survey item for undergraduate females and males for the university, by year of study and in four de-identified courses. The investigation found that females reported higher percentage agreement than males but there were smaller differences between males and females in more recent semesters. Differences between males and females by year of study also decreased over time with both reporting the same overall satisfaction in their first year of study in the latest semester’s data. Differences over four different courses with varying ratios of males and females showed that results varied widely between courses and males reported higher percentage agreement than females in one of the four courses. The findings showed that caution is needed when generalising results and interpreting differences in feedback between male and female students.
Second Language Speech Learning

My research focuses on perceptual approaches to second language speech learning, or pronunciation training. Two main approaches to perceptual training have been investigated in the literature: (1) perceptual fading in which learners are presented stimuli from opposite ends of a synthetic continuum in which the differences between the members of the non-native phonemic contrast have been exaggerated (Jamieson and Morosan, 1986), and (2) High-Variability Pronunciation Training (HVPT) in which learners are presented minimal pairs containing the non-native phonemic contrasts in forced-choice identification format (Logan et al., 1991). While these techniques, in particular HVPT, have been demonstrated to be effective in lab-based studies, they typically involve just one simple task, e.g. forced-choice identification, which the learner is required to repeat ad nauseum. To ensure that learners persist with training when a wider variety of phonemic contrasts are to be trained, I believe that a greater variety of tasks is required. In this poster, I present an experiment which compared two versions of HVPT, one employing an identification task and one employing a discrimination task. Future research will explore a wider variety of tasks in combination with the use of synthetic continua.
Can We Institute Medical Trust? An exploratory case study of patient-staff relations at a community health center in the Mississippi Delta

The purpose of this study was to use the concept of the patient-centered medical home (PCMH) model and the case of the community health center (CHC) to explore social interaction and trust between patients and medical providers. While the PCMH model is being championed as revolutionizing and improving healthcare delivery, little evidence has yet to support the formation of basic social and health mechanisms, such as trust, that would result in positive health outcomes. The model’s guidelines focus more on healthcare organization and information technology than developing interpersonal relationships and adapting services to meet the specific needs of diverse populations. Utilizing participant observation and informal interviews, qualitative evidence suggests that context-specific details may have more impact on healthcare delivery than methods currently addressed in the PCMH guidelines themselves.
