    Get PDF
    This paper explores some fundamental tasks associated with corporate governance: manager appraisal and compensation. Most of the empirical research in this area has been centered on Anglo-Saxon countries. Some European countries, such as Spain, have a very different governance tradition. Given this context, the work presented here has two objectives: 1.- To describe existing appraisal and compensation practices in Spain, comparing them with those used in the USA. 2.- To study the determinants of CEO compensation, and the relationship between CEO compensation and certain Board practices, using agency theoryAppraisal; compensation; agency

    Transgender people are constantly fighting for their rights, to be seen for who they are, and to be respected. When don’t ask, don’t tell was repealed on September 20, 2011, so many gays, lesbians, and bisexuals in the military celebrated their freedom to serve openly in the U.S. Armed Forces. In the years to come, Secretary of Defense Ash Carter stated June 2016, “We can’t allow barriers unrelated to a person’s qualifications to prevent us from recruiting and retaining those who can best accomplish the mission” (Gritz, 2019). Unfortunately, the ending of DADT did not include transgender soldier. If it had, would transgender people have been protected to serve openly? I will explore the many myths in why transgender people can’t serve in the military, but the focus will always be active-duty military and non-military perception on transgender people serving in the military. As I break down barriers for transgenders people to service openly in the military, I can expect an inclusive policy for transgender people.

    The Chandra Dust Scattering Halo of Galactic Center transient Swift J174540.7-290015

    We report the detection of a dust scattering halo around a recently discovered X-ray transient, Swift J174540.7-290015, which in early February of 2016 underwent one of the brightest outbursts (F_X ~ 5e-10 erg/cm^2/s) observed from a compact object in the Galactic Center field. We analyze four Chandra images that were taken as follow-up observations to Swift discoveries of new Galactic Center transients. After adjusting our spectral extraction for the effects of detector pileup, we construct a point spread function for each observation and compare it to the GC field before the outburst. We find residual surface brightness around Swift J174540.7-290015, which has a shape and temporal evolution consistent with the behavior expected from X-rays scattered by foreground dust. We examine the spectral properties of the source, which shows evidence that the object transitioned from a soft to hard spectral state as it faded below L_X ~ 1e36 erg/s. This behavior is consistent with the hypothesis that the object is a low mass X-ray binary in the Galactic Center.Comment: Accepted for publication in Ap

    A gradient-forming MipZ protein mediating the control of cell division in the magnetotactic bacterium Magnetospirillum gryphiswaldense

    Cell division needs to be tightly regulated and closely coordinated with other cellular processes to ensure the generation of fully viable offspring. Here, we investigate division site placement by the cell division regulator MipZ in the alphaproteobacterium Magnetospirillum gryphiswaldense, a species that forms linear chains of magnetosomes to navigate within the geomagnetic field. We show that M. gryphiswaldense contains two MipZ homologs, termed MipZ1 and MipZ2. MipZ2 localizes to the division site, but its absence does not cause any obvious phenotype. MipZ1, by contrast, forms a dynamic bipolar gradient, and its deletion or overproduction cause cell filamentation, suggesting an important role in cell division. The monomeric form of MipZ1 interacts with the chromosome partitioning protein ParB, whereas its ATP-dependent dimeric form shows non-specific DNA-binding activity. Notably, both the dimeric and, to a lesser extent, the monomeric form inhibit FtsZ polymerization in vitro. MipZ1 thus represents a canonical gradient-forming MipZ homolog that critically contributes to the spatiotemporal control of FtsZ ring formation. Collectively, our findings add to the view that the regulatory role of MipZ proteins in cell division is conserved among many alphaproteobacteria. However, their number and biochemical properties may have adapted to the specific needs of the host organism

    CYGNUS X-3: ITS LITTLE FRIEND’S COUNTERPART, THE DISTANCE TO CYGNUS X-3, AND OUTFLOWS/JETS

    Chandra observations have revealed a feature within 16'' of Cygnus X-3 that varied in phase with Cygnus X-3. This feature was shown to be a Bok globule that is along the line of sight to Cygnus X-3. We report on observations made with the Submillimeter Array to search for molecular emission from this globule, also known as Cygnus X-3's "Little Friend." We have found a counterpart in both [superscript 12]CO (2-1) and [superscript 13]CO (2-1) emission. From the velocity shift of the molecular lines we are able to find two probable distances based on the Bayesian model of Milky Way kinematics of Reid et al. For the LF velocity of −47.5 km s[superscript −1], we find distances of 6.1 ± 0.6 kpc (62% probability) and 7.8 ± 0.6 kpc (38% probability). This yields distances to Cyg X-3 of 7.4 ± 1.1 kpc and 10.2 ± 1.2 kpc, respectively. Based on the probabilities entailed, we take 7.4 ± 1.1 kpc as the preferred distance to Cyg X-3. We also report the discovery of bipolar molecular outflow, suggesting that there is active star formation occurring within the Little Friend

    How strength asymmetries shape multi-sided conflicts

    Get PDF
    Governments and multilateral organisations often attempt to influence multi-sided violent conflicts by supporting or undermining one of the conflicting parties. We investigate the (intended and unintended) consequences of strengthening or weakening an agent in a multi-sided conflict. Using a conflict network based on Franke and ÖztĂŒrk (J Public Econ 126:104–113, 2015), we study how changing the strength of otherwise symmetric agents creates knock-on effects throughout the network. Increasing or decreasing an agent’s strength has the same unintended consequences. Changes in the strength of an agent induce a relocation of conflict investments: Distant conflicts are carried out more fiercely. In line with previous results, asymmetry reduces aggregate conflict investments. In the case of bipartite networks, with two conflicting tacit groups with aligned interests, agents in the group of the (now) strong or weak agent face more intense conflicts. Furthermore, in conflicts where the (now strong or weak) agent is not involved, the probabilities of winning remain unchanged compared to the symmetric case.</p

    The VoiceApp System: Speech Technologies to Access the Semantic Web

    Proceedings of: 14th Conference of the Spanish Association for Artificial Intelligence, CAEPIA 2011, La Laguna, Spain, November 7-11, 2011Maximizing accessibility is not always the main objective in the design of web applications, specially if it is concerned with facilitating access for disabled people. In this paper we present the VoiceApp multimodal dialog system, which enables to access and browse Internet by means of speech. The system consists of several modules that provide different user experiences on the web. Voice Dictionary allows the multimodal access to the Wikipedia encyclopedia, Voice Pronunciations has been developed to facilitate the learning of new languages by means of games with words and images, whereas Voice Browser provides a fast and effective multimodal interface to the Google web search engine. All the applications in the system can be accessed multimodally using traditional graphic user interfaces such as keyboard and mouse, and/or by means of voice commands. Thus, the results are accessible also for motorhandicapped and visually impaired users and are easier to access by any user in small hand-held devices where graphical interfaces are in some cases difficult to employ.Research funded by projects CICYT TIN 2008-06742-C02-02/TSI, CICYT TEC 2008-06732-C02-02/TEC, CAM CONTEXTS (S2009/TIC-1485), and DPS 2008-07029-C02-02.Publicad

    El presente trabajo se ha centrado en el anĂĄlisis de la terra sigillata hispĂĄnica elaborada en los talleres malagueños, documentada en las excavaciones realizadas en el Teatro romano de MĂĄlaga y su entorno. La identificaciĂłn de las pastas de los materiales analizados han permitido aproximarnos a los distintos puntos de origen de la sigillata hispĂĄnica hallada en el principal edificio pĂșblico de Ă©poca romana excavado en la ciudad de MĂĄlaga, con un significativo porcentaje de las producciones elaboradas en los talleres de T.S.H. malagueñosThis article is based on terra sigillata hispanica analysis which taken place at MĂĄlaga workshops and it has been researched on MĂĄlaga Roman Theatre and its surroundings. Thanks to the identification of the pastes of the materials analysed, we have been able to come closer to SH points of origin which were found in the main public building, belonging to the Roman period, excavated in the city of malaga. We emphasize the high percentage of pieces made in MĂĄlaga T.S.H workshop
