Public Policy Influences on Academia in the European Union: A Snapshot of the Convergences Among HRM–Industrial Relations and CSR–Stakeholder Approach

The aim of this research is to examine the public policy influences on academic investigations that contain a substantial convergence among human resource management–industrial relations and corporate social responsibility–stakeholder approach by means of using bibliometric and content analyses of relevant publications in the Scopus and ScienceDirect databases. Totally, 160 publications were subject to bibliometric, cluster, and summative content analyses. In this context, this study claims that public policy in the EU influences academic investigations and scholars. The investigation draws attention to the importance of active participation of different public institutions and key stakeholders (e.g., trade unions, works councils, academic associations) that prepare a basis for collaboration, solidarity, and communication for strengthening EU social model, social dialogue, collective bargaining, and the protection of social rights. The research findings illuminate the fact that European public policies have significant effects on shaping and encouraging investigations that are considered within the scope of IR–HRM and CSR–SA. One of the most crucial recommendations of this study is that the investigations which are out of this framework can be considered quite idealistic. Therefore, researchers may attempt to publish more scientific investigations in frame of IR–HRM and CSR–SA to enhance the comprehensiveness and depth of these two clusters

Cold ultrarelativistic pulsar winds as potential sources of galactic gamma-ray lines above 100 GeV

The evidence of a line-like spectral feature at 130 GeV recently reported from some parts of the galactic plane poses serious challenges for any interpretation of this surprise discovery. It is generally believed that the unusually narrow profile of the spectral line cannot be explained by conventional processes in astrophysical objects, and, if real, is likely to be associated with Dark Matter. In this paper we argue that cold ultrarelativistic pulsar winds can be alternative sources of very narrow gamma-ray lines. We demonstrate that Comptonization of a cold ultrarelativistic electron-positron pulsar wind in the deep Klein-Nishina regime can readily provide very narrow distinct gamma-ray line features. To verify this prediction, we produced photon count maps based on the Fermi LAT data in the energy interval 100 to 140 GeV. We confirm earlier reports of the presence of marginal gamma-ray line-like signals from three regions of the galactic plane. Although the maps show some structure inside these regions, unfortunately the limited photon statistics do not allow any firm conclusion in this regard. The confirmation of 130 GeV line emission by low-energy threshold atmospheric Cherenkov telescope systems, in particular by the new 27 m diameter dish of the H.E.S.S. array, would be crucial for resolving the spatial structure of the reported hotspots, and thus for distinguishing between the Dark Matter and Pulsar origins of the `Fermi Lines'.Comment: 5 pages. 4 figure

Study of correlation among ploidy level and steroid glycoalkaloids content in resistance in cultivated and uncultivated potato species from an in vitro genebank

The present research was carried out with the aim to determine the correlation between ploidy level, steroid glycoalkaloids (SGAs) content and resistance against Late blight (Phytophthora infestans (Mont.) de Bary), and Colorado potato beetle (Leptinotarsa decemlineata (Say)) in cultivated and wild Solanum species preserved in the Potato Gene Bank of Czech Republic. In this study 27 species were included which consist of five cultivated and 22 wild species, with a total of 31 genotypes (four species represented by two accessions). In this study 70.97% of genotypes were evaluated as diploid, 3.23% were triploid, 19.35% tetraploid and 6.45% hexaploid as depicted from counting of chromosomes. The highest concentration, of foliage α-solanine (5,450 mg kg-1 ) and α-chaconine (9,420 mg kg-1 ) of dry matter was found in the specie S. yungasense 00070, whereas lowest 1.1 mg kg-1 and 2.3 mg kg-1 in S. pinnatisectum 00051, respectively, Tukey’s test of one way anova was performed for getting significance from the data obtained and found significant variation among species of steroid glycoalkaloids (SGA) content in dry weight at level of P ≤ 0.01. Leaf damages by Leptinotarsa decemlineata under field experiment circumstances were also recorded. In vitro study, S. bulbocastanum PIS 06-17 and S. bulbocastanum 00240 shown resistant to P. infestans upon inoculation of aggressive isolates and strong resistance was observed in S. stoloniferum 00295, S. sucrense 0062 and S. yungasense 0070. Nevertheless, there was no correlation of ploidy level, SGA contents and resistance to the CPB (r = 0.00) and late blight (r = 0.076) found in the investigated Solanum species

Towards the development of a community-based model for promoting cervical cancer prevention among Yoruba women in Ibadan Nigeria: Application of PEN-3 model

Through the identification of the barriers to the uptake of prevention services for cervical cancer and ways topromote prevention of cervical cancer in the community, this research study purposed the development of a community-based model for promoting cervical cancer prevention among Yoruba women living in Ibadan, Nigeria. An exploratory, descriptive design was used to collect data from 20 health workers and four policy makers using semi-structured interviews and key informant interviews respectively. The PEN-3 cultural model developed by Airhenbuwa in 1998guided the exploration of the barriers to the uptake of available prevention services for cervical cancer, and the ways topromote the prevention of cervical cancer. Three interrelated and interdependent primary domains, namely cultural identity,relationships and expectations, and cultural empowerment, form the basis of the PEN-3 model. Cultural identity emphasisesthe subjective responses in relation to the community and cervical cancer prevention

A novel design of multi-epitope based vaccine against Escherichia coli

Background: Multi-valent based vaccines have advantage over conventional vaccines because of its multi-faceted action targeted at antigen; thereby raising hope of a more sustained actions against allergens. Escherichia coli (E. coli) is a bacterium that is commonly found in the gut of humans and warm-blooded animals. An increasing number of outbreaks are associated with the consumption of fruits and vegetables (including sprouts, spinach, lettuce, coleslaw, and salad) thereby contamination may be due to contact with faeces from domestic or wild animals at some stages during cultivation or handling. Due to the reported increase in resistance to antibiotics used for Escherichia coli control; an effective vaccine is a would-be alternative of proven interest. Hence, a need for a rational, strategic, and efficient vaccine candidate against E.coli is of paramount necessity by the use of the most current bioinformatics tools to achieve this task. Method: In this study, immunoinformatics tools mined from diverse molecular databases were used  for a novel putative epitope based oral vaccine against E.coli. The prospective vaccine proteins were carefully screened and validated to achieve a high thorough-put three-dimensional protein structure. The eventual propsective vaccine candidate proteins was evaluated for its non-allergenicity, antigenicity, solubility, appropriate molecular weight testing and isoelectric point evaluation. Conclusion: The resultant vaccine candidate could serve as a promising anti-E.coli vaccine candidate. Immunoinformatics is a new field over pharmaco-therapeutics; this newest technology should continue to be a rescue from age-long traditional approach in vaccine developments

Detection of Extended VHE Gamma Ray Emission from G106.3+2.7 with VERITAS

We report the detection of very-high-energy (VHE) gamma-ray emission from supernova remnant (SNR) G106.3+2.7. Observations performed in 2008 with the VERITAS atmospheric Cherenkov gamma-ray telescope resolve extended emission overlapping the elongated radio SNR. The 7.3 sigma (pre-trials) detection has a full angular extent of roughly 0.6deg by 0.4deg. Most notably, the centroid of the VHE emission is centered near the peak of the coincident 12CO (J = 1-0) emission, 0.4deg away from the pulsar PSR J2229+6114, situated at the northern end of the SNR. Evidently the current-epoch particles from the pulsar wind nebula are not participating in the gamma-ray production. The VHE energy spectrum measured with VERITAS is well characterized by a power law dN/dE = N_0(E/3 TeV)^{-G} with a differential index of G = 2.29 +/- 0.33stat +/- 0.30sys and a flux of N_0 = (1.15 +/- 0.27stat +/- 0.35sys)x 10^{-13} cm^{-2} s^{-1} TeV^{-1}. The integral flux above 1 TeV corresponds to ~5 percent of the steady Crab Nebula emission above the same energy. We describe the observations and analysis of the object and briefly discuss the implications of the detection in a multiwavelength context.Comment: 5 pages, 2 figure

A new, very massive modular Liquid Argon Imaging Chamber to detect low energy off-axis neutrinos from the CNGS beam. (Project MODULAr)

The paper is considering an opportunity for the CERN/GranSasso (CNGS) neutrino complex, concurrent time-wise with T2K and NOvA, to search for theta_13 oscillations and CP violation. Compared with large water Cherenkov (T2K) and fine grained scintillators (NOvA), the LAr-TPC offers a higher detection efficiency and a lower backgrounds, since virtually all channels may be unambiguously recognized. The present proposal, called MODULAr, describes a 20 kt fiducial volume LAr-TPC, following very closely the technology developed for the ICARUS-T60o, and is focused on the following activities, for which we seek an extended international collaboration: (1) the neutrino beam from the CERN 400 GeV proton beam and an optimised horn focussing, eventually with an increased intensity in the framework of the LHC accelerator improvement program; (2) A new experimental area LNGS-B, of at least 50000 m3 at 10 km off-axis from the main Laboratory, eventually upgradable to larger sizes. A location is under consideration at about 1.2 km equivalent water depth; (3) A new LAr Imaging detector of at least 20 kt fiducial mass. Such an increase in the volume over the current ICARUS T600 needs to be carefully considered. It is concluded that a very large mass is best realised with a set of many identical, independent units, each of 5 kt, "cloning" the technology of the T600. Further phases may foresee extensions of MODULAr to meet future physics goals. The experiment might reasonably be operational in about 4/5 years, provided a new hall is excavated in the vicinity of the Gran Sasso Laboratory and adequate funding and participation are made available.Comment: Correspondig Author: C.

Seesaw Mass Matrix Model of Quarks and Leptons with Flavor-Triplet Higgs Scalars

In a seesaw mass matrix model M_f = m_L M_F^{-1} m_R^\dagger with a universal structure of m_L \propto m_R, as the origin of m_L (m_R) for quarks and eptons, flavor-triplet Higgs scalars whose vacuum expectation values v_i are proportional to the square roots of the charged lepton masses m_{ei}, i.e. v_i \propto \sqrt{m_{ei}}, are assumed. Then, it is investigated whether such a model can explain the observed neutrino masses and mixings (and also quark masses and mixings) or not.Comment: version accepted by EPJ

Prospects for Observations of Pulsars and Pulsar Wind Nebulae with CTA

The last few years have seen a revolution in very-high gamma-ray astronomy (VHE; E>100 GeV) driven largely by a new generation of Cherenkov telescopes (namely the H.E.S.S. telescope array, the MAGIC and MAGIC-II large telescopes and the VERITAS telescope array). The Cherenkov Telescope Array (CTA) project foresees a factor of 5 to 10 improvement in sensitivity above 0.1 TeV, extending the accessible energy range to higher energies up to 100 TeV, in the Galactic cut-off regime, and down to a few tens GeV, covering the VHE photon spectrum with good energy and angular resolution. As a result of the fast development of the VHE field, the number of pulsar wind nebulae (PWNe) detected has increased from one PWN in the early '90s to more than two dozen firm candidates today. Also, the low energy threshold achieved and good sensitivity at TeV energies has resulted in the detection of pulsed emission from the Crab Pulsar (or its close environment) opening new and exiting expectations about the pulsed spectra of the high energy pulsars powering PWNe. Here we discuss the physics goals we aim to achieve with CTA on pulsar and PWNe physics evaluating the response of the instrument for different configurations.Comment: accepted for publication in Astroparticle Physic

Gamma-rays from millisecond pulsars in Globular Clusters

Globular clusters (GCs) with their ages of the order of several billion years contain many final products of evolution of stars such as: neutron stars, white dwarfs and probably also black holes. These compact objects can be at present responsible for the acceleration of particles to relativistic energies. Therefore, gamma-ray emission is expected from GCs as a result of radiation processes occurring either in the inner magnetosperes of millisecond pulsars or in the vicinity of accreting neutron stars and white dwarfs or as a result of interaction of particles leaving the compact objects with the strong radiation field within the GC. Recently, GeV gamma-ray emission has been detected from several GCs by the new satellite observatory Fermi. Also Cherenkov telescopes reported interesting upper limits at the TeV energies which start to constrain the content of GCs. We review the results of these gamma-ray observations in the context of recent scenarios for their origin.Comment: 20 pages, 9 figures, will be published in Astrophysics and Space Science Series (Springer), eds.
