First implications of LHCb data on models beyond the Standard Model

We discuss the theoretical and experimental details of two of the main results obtained by LHCb with the 2011 data, namely the measurement of the mixing-induced CP-violation in the decay B_s -> J/psi phi and the upper limits on the decays B_(s) -> mu+ mu-. Then we describe the possible strategies to obtain new constraints on two different New Physics models in the light of these results.Comment: 5 pages, Proceedings of "QCD@Work 2012" - June 18-21, 2012 - Lecce (Italy

Measurements of charged-particle distributions with the ATLAS detector

Inclusive charged-particle measurements probe the low-energy region of the non-perturbative quantum chromodynamics. The ATLAS collaboration has recently measured the charged-particle multiplicity and its dependence on transverse momentum and pseudorapidity in special data sets with low LHC beam currents, recorded at centre-of-mass energies of 8 TeV and 13 TeV. The measurements at 8 TeV cover a wide spectrum using charged-particle selections with minimum transverse momentum of both 100 MeV and 500 MeV and in various phase space regions of low and high charged-particle multiplicities, some of which are studied for the first time by ATLAS. The measurements at 13 TeV also present detailed studies with a minimum transverse momentum of both 100 MeV and 500 MeV. The measurements are compared with predictions of various tuned Monte Carlo generators and are found to provide strong constraints on these. None of the Monte Carlo generators with their respective tunes are able to reproduce all the features of the data.Comment: Proceedings of Low-x Meeting 201

The determinants of regional specialisation in business services: agglomeration economies, vertical linkages and innovation

The article accounts for the determinants of sectoral specialisation in business services (BS) across the EU-27 regions as determined by: (i) agglomeration economies (ii) the region-specific structure of intermediate linkages (iii) technological innovation and knowledge intensity and (iv) the presence of these factors in neighbouring regions. The empirical analysis draws upon the REGIO panel database over the period 1999–2003. By estimating a Spatial Durbin Model, we find significant spatial effects in explaining regional specialisation in BS. Our findings show that, besides urbanisation economies, the spatial structure of intermediate sectoral linkages and innovation, in particular Information and Communication Technologies (ICTs), are important determinants of specialisation in BS. The article contributes to the debate on the global versus local determinants of regional specialisation in BS by restating the importance of the regional sectoral structure besides that of urbanisation. We draw policy implications by rejecting the ‘footloose hypothesis’ for BS

Microbiome-gut-brain axis and toll-like receptors in parkinson\u2019s disease

Parkinson’s disease (PD) is a progressively debilitating neurodegenerative disease characterized by α-synucleinopathy, which involves all districts of the brain-gut axis, including the central, autonomic and enteric nervous systems. The highly bidirectional communication between the brain and the gut is markedly influenced by the microbiome through integrated immunological, neuroendocrine and neurological processes. The gut microbiota and its relevant metabolites interact with the host via a series of biochemical and functional inputs, thereby affecting host homeostasis and health. Indeed, a dysregulated microbiota-gut-brain axis in PD might lie at the basis of gastrointestinal dysfunctions which predominantly emerge many years prior to the diagnosis, corroborating the theory that the pathological process is spread from the gut to the brain. Toll-like receptors (TLRs) play a crucial role in innate immunity by recognizing conserved motifs primarily found in microorganisms and a dysregulation in their signaling may be implicated in α-synucleinopathy, such as PD. An overstimulation of the innate immune system due to gut dysbiosis and/or small intestinal bacterial overgrowth, together with higher intestinal barrier permeability, may provoke local and systemic inflammation as well as enteric neuroglial activation, ultimately triggering the development of alpha-synuclein pathology. In this review, we provide the current knowledge regarding the relationship between the microbiota-gut–brain axis and TLRs in PD. A better understanding of the dialogue sustained by the microbiota-gut-brain axis and innate immunity via TLR signaling should bring interesting insights in the pathophysiology of PD and provide novel dietary and/or therapeutic measures aimed at shaping the gut microbiota composition, improving the intestinal epithelial barrier function and balancing the innate immune response in PD patients, in order to influence the early phases of the following neurodegenerative cascade

Phenomenological tests of the Two-Higgs-Doublet Model with MFV and flavour-blind phases

In the context of a Two-Higgs-Doublet Model in which Minimal Flavour Violation (MFV) is imposed, one can allow the presence of flavour-blind CP-violating phases without obtaining electric dipole moments that overcome the experimental bounds. This choice permits to accommodate the hinted large phase in the $B_s$ mixing and, at the same time, to soften the observed anomaly in the relation between $\epsilon_K$ and $S_{\psi K_S}$.Comment: 8 pages, 2 figures, Proceedings of "DISCRETE 2010" - December 6-11, 2010 - Rome (Italy

Role of spontaneous plants as a reservoir of alternative hosts for Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan) (Hymenoptera, Eulophidae) in citrus groves

The role spontaneous plants could eventually play towards populations of two exotic parasitoids, Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan), was investigated in five Sicilian citrus groves. Both species were obtained from two herbs typically living beneath the citrus trees in the period of scarce availability of P. citrella larvae on citrus plants, and precisely: S. petiolatus was reared from Cosmopterix pulcherimella Chambers, leafminer on Parietaria diffusa M. et K., while C. phyllocnistoides on the same species and on a Liriomyza species associated to Mercurialis annua L., these last two host records being new for the parasitoid. Vegetational diversity can then enhance survival and maintenance of populations of exotic parasitoids in citrus agroecosystem, providing them with alternative hosts. The incidence of parasitism of S. petiolatus and C. phyllocnistoides on non-target hosts was, however, so low (2.8% for S. petiolatus on C. pulcherimella, and 8.3% and 3.3% for C. phyllocnistoides on C. pulcherimella and Liriomyza sp. respectively) that a negative impact on both native leafminer and autochthonous parasitoid populations can be excluded

ABSTRACT MARIA VALENTINA. The Influence Self Efficacy and Motivation Toward Job Perfomance on Employee PT Surya Mustika Nusantara. Skripsi, Jakarta: Study Program of Economic Education, Concentration in Office Administration Education, Department of Economics and Administration, Faculty Economics, State University of Jakarta 2015. This research conducted to find out if there is Influence Self Efficacy and Motivation of Job Perfomance on Employee PT Surya Mustika Nusantara. This research was conducted for two months starting November until December 2014. The research method used is survey method with causality approach. This is the entire population of affordable employee research is part of the marketing of 75 people. The sample used as many as 65 people using simple random sampling technique. Job Perfomance data achieved from sekunder data performance appraisal directed from PT Surya Mustika Nusantara for period of December 2014, X variabel (Self Efficacy) using replica New General Self Efficacy (NGSE) and X2 1 variabel (Motivation) using skala Likert. Techniques of data analysis using SPSS 17.0. from the result of F-test, found that Self Efficacy and Motivation simultaneously influence to Job Perfomance seen from F count (30.294) > F tabel (3,15). T-test result in t count of X (Self Efficacy) registration 4,497 and –t tabel of 1,67, because 4,497 t then it can be inferred that there was a significant direct influence between motivation of the job performance. Based on the research path analysis, the magnitude of the influence of self efficacy (X1) which directly on job performance (Y) is 0,202 or 20,2% and the effect was moderated by motivation (X2tabel) is 0,275% or 27,5%. In addition to the magnitude of the effect of motivation (X2) which is directly on job performance (Y) is 0,147 or 14,7%. Conclussions of this study is that there are influences between self efficacy and motivation to job performance of PT. Surya Mustika Nusantara
