Internal marketing and talent management as integral elements of employer branding strategies
The paper presents internal marketing and talent management as key elements determining effective introduction of employer branding strategy. Nowadays tendencies to interdisciplinarity force organizations to search for concepts from different areas of science and combine them for most effective market performance. That is the reason for presentation of two aspects of employer branding – from HRM and marketing perspectives, in the paper. The paper is aimed at presentation and discussion of internal marketing and talent management as elements of overall strategy of organisation in the scope of its competitive advantage gaining.

A Reconfigurable Gate Architecture for Si/SiGe Quantum Dots
We demonstrate a reconfigurable quantum dot gate architecture that
incorporates two interchangeable transport channels. One channel is used to
form quantum dots and the other is used for charge sensing. The quantum dot
transport channel can support either a single or a double quantum dot. We
demonstrate few-electron occupation in a single quantum dot and extract
charging energies as large as 6.6 meV. Magnetospectroscopy is used to measure
valley splittings in the range of 35-70 microeV. By energizing two additional
gates we form a few-electron double quantum dot and demonstrate tunable tunnel
coupling at the (1,0) to (0,1) interdot charge transition.Comment: Related papers at http://pettagroup.princeton.ed
Food Webs in Long Island Sound: Review, Synthesis and Potential Applications
Understanding food web structure and dynamics of ecological systems is a key element in the development of more effective environmental assessment and management procedures. Although various components of the Long Island Sound (LIS) ecosystem have been studied in some detail, a framework for food web based research has been lacking. The objectives of this study were to: a) collect and review all pertinent data available in the scientific literature and technical reports on food web components and interactions in different sections of Long Island Sound; b) based on this review, refine initial conceptual food web models and extract pertinent data as available for input into the trophic modeling system Ecopath; c) using the Ecopath models constructed, identify apparent critical food web components and functional groups (particularly those influenced by human activities and management decisions) in LIS, their potential influence on ecosystem dynamics, important linkages along the food web, and the nature of the food web dynamics; and d) make an overall assessment of the gaps in our knowledge and recommendations as to how the work can be built on, and how information from food web analyses such as these and the models themselves, can be used to support management efforts focused on the vital resources of Long Island Sound
Investigation of Mobility Limiting Mechanisms in Undoped Si/SiGe Heterostructures
We perform detailed magnetotransport studies on two-dimensional electron
gases (2DEGs) formed in undoped Si/SiGe heterostructures in order to identify
the electron mobility limiting mechanisms in this increasingly important
materials system. By analyzing data from 26 wafers with different
heterostructure growth profiles we observe a strong correlation between the
background oxygen concentration in the Si quantum well and the maximum
mobility. The highest quality wafer supports a 2DEG with a mobility of 160,000
cm^2/Vs at a density 2.17 x 10^11/cm^2 and exhibits a metal-to-insulator
transition at a critical density 0.46 x 10^11/cm^2. We extract a valley
splitting of approximately 150 microeV at a magnetic field of 1.8 T. These
results provide evidence that undoped Si/SiGe heterostructures are suitable for
the fabrication of few-electron quantum dots.Comment: Related papers at http://pettagroup.princeton.ed
Collective Quadrupole Excitations in Transitional Nuclei
The generalized Bohr Hamiltonian was used to describe the low-lying collective excitations in even-even isotopes of Ru, Pd, Te, Ba and Nd. The Strutinsky collective potential and cranking inertial functions were obtained using the Nilsson potential. The effect of coupling with the pairing vibrations is taken into account approximately when determining the inertial functions. The calculation does not contain any free parameter
Social media actions and interactions: The role of the Facebook and Twitter during the 2014 European Parliament elections in the 28 EU nations.
Most political parties across the democratic sphere have created their own spaces within social media. While ostensibly studies show that social media is being utilized by political parties to further their electoral goals, the uses of their social media profiles by visitors is largely beyond official control without devoting significant resources to moderation. This study will be the first to gather data that allows us to detect patterns of participation within and potentially across nations, but in particular within nations and across parties to determine the extent that visitors use social media to promote parties (through liking and sharing) or for entering comments on party posts or for entering into discussions with other visitors. We specifically seek to understand whether we can detect evidence of a political ecosystem in which visitors visit multiple party profiles, enter debates across differing profiles and so contribute to something that might resemble an informed and engaged public sphere
Molecular Imaging of Petroleum Asphaltenes by Scanning Tunneling Microscopy: Verification of Structure from 13C and Proton Nuclear Magnetic Resonance Data
Scanning tunneling microscopy (STM) was used to verify the molecular structure of Maya asphaltene which had been derived from combined 13C and proton nuclear magnetic resonance (NMR) experiments. Petroleum asphaltenes are known to contain large polynuclear aromatic centers with aliphatic sidechains. Average molecular models of Maya asphaltenes were derived using studies which included combined proton and 13C NMR data to determine total aromatic carbon content and the ratio of peripheral to internal aromatic ring carbons. These parameters permitted estimating the average number of aromatic rings per condensed cluster.
These Maya asphaltenes were imaged by scanning tunneling microscopy (STM) in a dilute solution of tetrahydrofuran on highly oriented pyrolytic graphite. The sizes and structures of the asphaltenes as observed by STM are in reasonable agreement with these average molecular models. We observed asymmetric structures whose largest dimension averaged 10.4 Å ± 1.9 Å from 24 separate images. The condensed ring portions of three representative NMR derived molecular models yielded an average dimension of 11.1 Å ± 1.4 Å
