Enhancing organizational performance with social media use: the catalysing effect of corporate entrepreneurship

Social Media use has become pervasive and firms are increasingly relying on it, not only to relate to customers, but also to leverage internal processes like innovation. The strategic use of these tools can facilitate also the entrepreneurial orientation of the firm, as it provides useful knowledge which can make the firm more entrepreneurial, stimulating it to find new opportunities or innovative ideas where other companies do not recognize them. However, despite the relevance of the phenomenon in current hyper-competitive environments, empirical research on the topic remains scarce. To shed some light on the issue, the main purpose of the paper is to examine how Social Media use impacts the different dimensions of corporate entrepreneurship (new business venturing, innovativeness, proactiveness and self-renewal), enhancing also organizational performance. The study is intended to extend knowledge on this topic, by providing understanding of the path firms should take to benefit from Social Media use to become more entrepreneurial and achieve higher organizational performance, developing and nurturing competitive advantages. The paper analyses data obtained from a sample of 201 technological firms located in Spain. The methodology used is Structural equation modelling with LISREL analysis. Findings confirms how the use of Social Media tools positively impacted all the different dimensions of corporate entrepreneurship, translating also in enhanced performance. This paper contributes to the literature by empirically confirming in a structural model how Social Media use helps to create business value, by enhancing proactive behaviours, promoting strategic renewal inside the firm and increasing innovativeness and new business venturing and displaying the internal and sequential relationships among these dimensions.Universidad de Málaga.

Magnetic Collapse of a Neutron Gas: No Magnetar Formation

A degenerate neutron gas in equilibrium with a background of electrons and protons in a magnetic field exerts its pressure anisotropically, having a smaller value perpendicular than along the magnetic field. For critical fields the magnetic pressure may produce the vanishing of the equatorial pressure of the neutron gas, and the outcome could be a transverse collapse of the star. This fixes a limit to the fields to be observable in stable pulsars as a function of their density. The final structure left over after the implosion might be a mixed phase of nucleons and meson ($\pi^{\pm,0},\kappa^{\pm,0}$) condensate (a strange star also likely) or a black string, but no magnetar at all.Comment: 5 pages, 1 latex file, 1 encapsulated figure.

Let\u27s Be Cautious Friends: The Ethical Implications of Social Networking for Members of the Judiciary

In recent advisory opinions, courts and ethics committees have considered whether and to what extent judges may use social networking sites such as Facebook without violating the applicable code of judicial conduct. While the committees agree that judges may generally use social networking sites, they disagree as to whether judges may use those sites to connect with lawyers who have appeared or may appear in a proceeding before them. Four states—California, Florida, Massachusetts, and Oklahoma—forbid judges frombecoming online “friends” with attorneys who may appear before them in court, while four states—Ohio, Kentucky, New York, and South Carolina—allow it, albeit with caution. This Article examines the recent trend in advisory opinions governing the use of social media by members of the judiciary and provides practical advice for judges to conform to the code of judicial conduct

Discovery of Breathalyzer Source Code in DUI Prosecutions

In driving under the influence (DUI) cases, prosecutors habitually rely on the results from breathalyzer tests as proof of the defendant’s blood alcohol level at the time of arrest. In response, DUI defendants often attempt to compel discovery of the source code contained in the test device, which can reveal whether the breath test at issue was performed accurately. Despite the popularity of this strategy, nearly all states to consider the issue have denied the defendant’s motion for discovery of breathalyzer source code. The majority of courts construe state and federal rules of criminal procedure to limit discovery orders to information within the “possession, custody or control” of the prosecution and summarily hold that breathalyzer source code is not in the State’s possession or control. Absent a contractual agreement granting the State proprietary rights to the code, the courts have failed to articulate a clear definition of what it means to be in possession, custody, or control of breathalyzer source code. This Article explores the classification of breathalyzer source code, the discovery rules surrounding its disclosure, and the implications of its protected legal status

The Gospel According to Andrei: Biblical Narrative in the Films of Andrei Tarkovsky

Although Soviet-era Russian filmmaker Andrei Tarkovksy may be known primarily for the tactile quality of his filmmaking, the thematic grandeur of his storytelling, and his abstract, poetic understanding of time, it is also worth noting the overt intertextuality of his cinematic portfolio. My senior project examines the ways in which Tarkovsky layers different reference points toward three biblical narratives: beginning with the Crucifixion, moving to the Binding of Isaac, and ending with the Return of the Prodigal Son. Tarkovsky applies biblical allusion, as well as the reconstruction of biblical narratives in a modern setting, in order to examine the structure of these classic stories, and ultimately reconsider our understanding of Christian Apocalypse

Chromosomal instability in Afrotheria: fragile sites, evolutionary breakpoints and phylogenetic inference from genome sequence assemblies

Background: Extant placental mammals are divided into four major clades (Laurasiatheria, Supraprimates, Xenarthra and Afrotheria). Given that Afrotheria is generally thought to root the eutherian tree in phylogenetic analysis of large nuclear gene data sets, the study of the organization of the genomes of afrotherian species provides new insights into the dynamics of mammalian chromosomal evolution. Here we test if there are chromosomal bands with a high tendency to break and reorganize in Afrotheria, and by analyzing the expression of aphidicolin-induced common fragile sites in three afrotherian species, whether these are coincidental with recognized evolutionary breakpoints. Results: We described 29 fragile sites in the aardvark (OAF) genome, 27 in the golden mole (CAS), and 35 in the elephant-shrew (EED) genome. We show that fragile sites are conserved among afrotherian species and these are correlated with evolutionary breakpoints when compared to the human (HSA) genome. Inddition, by computationally scanning the newly released opossum (Monodelphis domestica) and chicken sequence assemblies for use as outgroups to Placentalia, we validate the HSA 3/21/5 chromosomal synteny as a rare genomic change that defines the monophyly of this ancient African clade of mammals. On the other hand, support for HSA 1/19p, which is also thought to underpin Afrotheria, is currently ambiguous. Conclusion: We provide evidence that (i) the evolutionary breakpoints that characterise human syntenies detected in the basal Afrotheria correspond at the chromosomal band level with fragile sites, (ii) that HSA 3p/21 was in the amniote ancestor (i.e., common to turtles, lepidosaurs, crocodilians, birds and mammals) and was subsequently disrupted in the lineage leading to marsupials. Its expansion to include HSA 5 in Afrotheria is unique and (iii) that its fragmentation to HSA 3p/21 + HSA 5/21 in elephant and manatee was due to a fission within HSA 21 that is probably shared by all Paenungulata

Analyzing the drivers of knowledge management processes in spanish hotels

La gestión del conocimiento y la gestión de relaciones con clientes (CRM) han surgido como iniciativas estratégicas claves en el entorno competitivo actual. A pesar de que hoteles de todo el mundo están implementando tales iniciativas con objeto de personalizar su servicio y mejorar así sus resultados, la investigación sobre la temática es aún limitada. Los estudios existentes no muestran resultados concluyentes, ni describen claramente qué factores determinan el éxito a la hora de poner en marcha dichas iniciativas estratégicas. Con objeto de cubrir este gap, usando una muestra de 93 hoteles españoles, analizamos cuáles son los determinantes del éxito de los procesos de gestión del conocimiento y cuál es su impacto real en el desempeño organizativo, usando una metodología de ecuaciones estructurales (PLS). Los resultados subrayan el papel determinante que juegan las variables organizativas y la disposición tecnológica como determinantes significativos de la gestión del conocimiento.Universidad de Málaga.
