Uncovering recruitment as a strategic lever for various forms of organizational capital

Whereas the structuring and growth of the firm have long been central to conceptual development in strategy research, the literature has largely ignored how a fundamental practice such as recruitment can be of strategic importance for the sustenance of the firm’s growth. The present study introduces recruitment as a strategic practice and elaborates on how this practice is crucial in creating and editing social and economic capital of the firm and how this interplays with its growth. It suggests three entrenchments – vertical, horizontal, and lateral – for striking a balance between the firm’s explorative (diversification) and exploitative (specialization) activities for creating and modifying its competence base through strategic recruitment.

Multi-Parameter Fluctuation Effects on InGaAsP/InP Geiger-Mode Avalanche Photodiodes

For Geiger-mode avalanche photodiodes, a statistical method is advanced to establish the quantitative correlation between the controllability of structure parameters and the homogeneity of device properties. Setting many parameters fluctuating independently and simultaneously, the collective effect of multi-parameters can be straightly obtained. For a typical InGaAsP/InP single- photon avalanche diode, it is seen that device homogeneity with excess bias fluctuation within 50% requires uncertainty in layer thickness and doping level better than ~3%.
Basic exclusivity graphs in quantum correlations

A fundamental problem is to understand why quantum theory only violates some noncontextuality (NC) inequalities and identify the physical principles that prevent higher-than-quantum violations. We prove that quantum theory only violates those NC inequalities whose exclusivity graphs contain, as induced subgraphs, odd cycles of length five or more, and/or their complements. In addition, we show that odd cycles are the exclusivity graphs of a well-known family of NC inequalities and that there is also a family of NC inequalities whose exclusivity graphs are the complements of odd cycles. We characterize the maximum noncontextual and quantum values of these inequalities, and provide evidence supporting the conjecture that the maximum quantum violation of these inequalities is exactly singled out by the exclusivity principle.
The Political Economy of Trade Policy: Empirical Approaches

In order to explain the prevalence and persistence of trade protection, a large body of work that departs from the notion of welfare maximizing governments and emphasizes instead political-economic determinants of policy has recently emerged. This survey paper summarizes and evaluates analytically the empirical component of this literature. We discuss a broad set of empirical findings which provide a convincing confirmation of the presence and significance of political economy influences. We also discuss some puzzles and controversies that have emerged in recent work.
Bargained Wages in Decentralized Wage-Setting Regimes

Collective wage agreements still play an important role in the German wage bargaining system. However, there is a critical debate in Germany whether collective agreements deliver the flexibility needed by firms to adjust to the needs of international competition and technological change. In recent years, the social partners in some industries have responded to this possible lack of flexibility by introducing so called opening clauses into their collective bargaining agreements. These allow firms to deviate from their collective agreement under certain conditions. The aim of this paper is to empirically analyze the prevalence of opening clauses in the German manufacturing sector and their impact on the wage structure. To provide a basis for the empirical analyses, a survey on the existence and intensity of opening clauses in central collective agreements has been conducted. Thereby, these sectoral data about opening clauses are exactly combined with those from the German Structure of Earnings Survey 1995 and 2001, a linked employer-employee dataset from German official statistics. The results show the number of collective bargaining agreements containing opening clauses increasing remarkably since 1991. Furthermore, the implementation of opening clauses into collective contracts creates significant effects on wages.
Faber polynomials and Poincar\'e series

In this paper we consider weakly holomorphic modular forms (i.e. those meromorphic modular forms for which poles only possibly occur at the cusps) of weight $2-k\in 2\Z$ for the full modular group $\SL_2(\Z)$. The space has a distinguished set of generators $f_{m,2-k}$. Such weakly holomorphic modular forms have been classified in terms of finitely many Eisenstein series, the unique weight 12 newform $\Delta$, and certain Faber polynomials in the modular invariant $j(z)$, the Hauptmodul for $\SL_2(\Z)$. We employ the theory of harmonic weak Maass forms and (non-holomorphic) Maass-Poincar\'e series in order to obtain the asymptotic growth of the coefficients of these Faber polynomials. Along the way, we obtain an asymptotic formula for the partial derivatives of the Maass-Poincar\'e series with respect to $y$ as well as extending an asymptotic for the growth of the $\ell$-th repeated integral of the Gauss error function at $x$ to include $\ell\in \R$ and a wider range of $x$.
Envelope tracking amplification with reduced slew-rate and bandwidth envelopes

This paper presents an Envelope Tracking Pow- er Amplifier whose architecture includes a Hybrid Envelope Amplifier (HEA) and an algorithm to adapt the envelope’s characteristics to the HEA’s limitations. The HEA attempts to combine the high efficiency of a switched amplifier with the wide band capabilities of a linear amplifier. A modified Slew Rate (SR) reduction algorithm cope with the bandwidth and SR limitations of the HEA. On the other hand, the non-linearities introduced by this Envelope Amplifier (EA) and by the dynamic supply are compensated using Digital Pre-Distortion. Results show that these non-linearities are compensable and that the architecture offers higher efficiency figures compared to the conventional linear EA
DISTRIBUTED MODELING FOR ROAD AUTHORITIES

A great challenge for road authorities is to improve the effectiveness and efficiency of their core processes by improving data exchange and sharing using new technologies such as building information modeling (BIM). BIM has already been successfully implemented in other sectors, such as architecture. But the civil infrastructure sector still lags behind. This paper reports the core findings of the research undertaken in an FP7 project called V-Con, Virtual Construction for Roads. In this EU-funded project, BIM technologies are being implemented at road authorities. Typical interest areas of the road authorities are the programming phase, in which requirements management and systems engineering play a key role, as well as the use and maintenance phase, in which asset management is essential. These processes require special attention in information management for road authorities. Furthermore, road authorities are interested in standardized “as designed” road information. IFC would be a good standard for this, but there is no “IFC for roads” yet. But road authorities are also interested in information about the context of the road, as usually defined in GIS. So GIS should be linked to the envisaged system as well. Finally, it was observed that there is a need in the infrastructure sector for so-called concept libraries, libraries with objects and concepts that can be located and managed on different levels (from project-specific to national and global). It was found that the support of such libraries requires changes in the way information modeling and exchange is commonly approached. The new approach is called “distributed modeling” and will be elaborated in this paper.
Self-reported psychopathy and its association with criminal cognition and antisocial behavior in a sample of university undergraduates.

The present study examined the construct of psychopathy (as assessed via self-report) and its relation to criminal attitudes, criminal thinking styles, and self-reported antisocial behavior in a sample of 248 Canadian university undergraduate students. Participants completed 3 forensic self-report measures (Self-Report Psychopathy: Short Form; Criminal Sentiments Scale–Modified; Criminal Thinking Profile), and a measure of self-reported antisocial behaviour. Moderate to large positive correlations were observed among the 3 forensic self-report measures. Self-reported antisocial behaviours, organized into 2 groups reflecting serious infrequent antisocial behaviours and more frequent but generally less serious rule violations, were significantly positively correlated with several indexes of psychopathy and criminal cognition. Multiple regression analyses revealed that, controlling for Criminal Thinking Profile and Criminal Sentiments Scale–Modified scales, the Self-Report Psychopathy: Short Form Antisocial scale uniquely predicted serious self-reported antisocial behaviour while its Lifestyle scale uniquely predicted more frequent and less severe antisocial behaviour. The present study supports the construct validity of self-report forensic measures in a university undergraduate sample and the relations of self-reported psychopathic traits to criminal cognition and antisocial behaviour.
Das Fourierspektrum von Gesichtsbildern in Photographie und Kunst und dessen Einfluss auf die Gesichtswahrnehmung

When artists portray human faces, they generally endow their portraits with properties that render the faces esthetically more pleasing. To obtain insight into the changes introduced by artists, we compared Fourier power spectra in photographs of faces and in portraits by artists. Our analysis was restricted to a large set of monochrome or lightly colored portraits from various Western cultures and revealed a paradoxical result. Although face photographs are not scale-invariant, artists draw human faces with statistical properties that deviate from the face photographs and approximate the scale-invariant, fractal-like properties of complex natural scenes. This result cannot be explained by systematic differences in the complexity of patterns surrounding the faces or by reproduction artifacts. In particular, a moderate change in gamma gradation has little influence on the results. Moreover, the scale-invariant rendering of faces in artists’ portraits was found to be independent of cultural variables, such as century of origin or artistic techniques. We suggest that artists have implicit knowledge of image statistics and prefer natural scene statistics (or some other rules associated with them) in their creations. Fractal-like statistics have been demonstrated previously in other forms of visual art and may be a general attribute of esthetic visual stimuli.
The Co-movement between Non-GM and GM Soybean Price in China: Evidence from China Futures Market

The price variability of agricultural commodities reached record levels in 2008, and again more recently in 2010, raising concerns about this increased price volatility would be temporal or structural. The Chinese soybean futures market is the second largest in the world in terms of trading volume. There are two soybean futures contracts in China: non-GM and GM. This study examines the volatility determinants as well as seasonality of non-GM and GM soybean futures prices traded in Dalian Commodity Exchange from 2005 to 2014. Also, we test the co-movement between these two soybeans markets. We analyze the volatility by incorporating changes in important economic variables into the Dynamic Conditional Correlation-Generalized Autoregressive Conditional Heteroskedastic (DCC-GARCH) model. This research provides statistical evidence that the futures prices of soybeans in China are being influenced by the increasing consumption of soybeans, the import quantity of soybean, the trading volume in futures market and weather.
Compact Modified Swastika Shape Patch Antenna for WLAN/WiMAX Applications

A compact simple structure modified Swastika shape multiband patch antenna is designed and investigated. The antenna, which occupies an overall dimension of 0. 305λ × 0. 305λ × 0. 012λ at lower frequency, has a simple structure which comprises of a planar wide square slot in the ground with four slits and Swastika shape radiation patch with a rectangular slot. The proposed Swastika shape antenna was designed and analyzed by using a finite element method based high frequency structural simulator HFSS. The experimental and numerical results exhibit that the antenna operates over the frequency ranges 950 MHz (2.28–3.23 GHz), 660 MHz (3.28–3.94 GHz), and 1120 MHz (5.05–6.17 GHz) suitable for WLAN (2.4/5.2/5.8 GHz) and WiMAX 2.5/3.5/5.5 GHz applications. It has a good omnidirectional radiation pattern and reaches 3.97 dBi at 2.44 GHz, 4.04 dBi at 3.5 GHz, and 3.25 dBi at the band of 5.98 GHz. A prototype is fabricated and then measured. The experimental and simulation results show good impedance bandwidth, radiation pattern, and stable gain across the operating bands.
Progress from 1989 to 1992 in understanding the circulation of the western mediterranean-sea

The present paper describes the major results obtained from 1989 to 1992 by the EUROMODEL group in studying the circulation in the Western Mediterranean Sea. Particular emphasis has been given to the physical processes responsible for seasonal and mesoscale variabilities. Observations (in situ and satellite), together with theoretical, physical and numerical models, have been widely used in the course of these studies. Attention has been focused on the dynamics of the northern basin (deep water formation, dynamics of the Northern Mediterranean Current, circulation and shelf/slope interaction in the Balearic Sea) and of the southern basin (Alboran Sea circulation, instabilities of the Algerian Current). The straits dynamics have been studied with particular reference to the Corsica channel. Preliminary runs of a basin-scale circulation model of the Western Mediterranean Sea forced by the straits are also presented. They are shown to be capable of generating a cyclonic circulation in the western basin.
ThunderKAT: The MeerKAT Large Survey Project for Image-Plane Radio Transients

ThunderKAT is the image-plane transients programme for MeerKAT. The goal as outlined in 2010, and still today, is to find, identify and understand high-energy astrophysical processes via their radio emission (often in concert with observations at other wavelengths). Through a comprehensive and complementary programme of surveying and monitoring Galactic synchrotron transients (across a range of compact accretors and a range of other explosive phenomena) and exploring distinct populations of extragalactic synchrotron transients (microquasars, supernovae and possibly yet unknown transient phenomena) - both from direct surveys and commensal observations - we will revolutionise our understanding of the dynamic and explosive transient radio sky. As well as performing targeted programmes of our own, we have made agreements with the other MeerKAT large survey projects (LSPs) that we will also search their data for transients. This commensal use of the other surveys, which remains one of our key programme goals in 2016, means that the combined MeerKAT LSPs will produce by far the largest GHz-frequency radio transient programme to date.
Formulation and evaluation of Tobramycin Sulphate In situ gel for conjunctivitis.

The poor bioavailability and therapeutic response exhibited by the conventional eye drops due to rapid precorneal elimination of the drug may be overcome by the use of in situ gelling systems that are instilled as drops into the eye and undergo a sol-togel transition in the cul-de-sac. The present study was designed to prepare and investigate the sustained release in situ ocular gels of Tobramycin sulphate using gelrite as gel forming polymer, which is used in the treatment of various bacterial infections. The formulations were evaluated with various parameters like clarity, pH, gelling capacity, rheological study, in vitro studies, sterility and isotonicity. All the formulations were transparent, having consistency and drug content was found to be in acceptable range. Among all the formulations, F3 was selected as the best formulation. The best selected F3 formulation was found to be stable at short term stability studies as per ICH guidelines. The overall results of this study supports that the Gelrite based vehicle could be used for controlled drug release that exhibits a greater potential for conjunctivitis. It also contributes to a great extent to patient compliance as the dosage is regulated as one drop of the solution to be instilled into the eye once a day.
De-westernising research methodologies: Alternative approaches to research for higher education curricula in developing countries

This paper looks at research quality from a society's or a region's specific knowledge needs, placing attention on external factors such as the value of western education, knowledge and research methods and the role of foreign research training. The paper, theoretically informed through emerging literature from different parts of the world, examines the existence of or the potential for developing alternative ways of learning and distinctive understandings of local knowledge and the need to make them part of formal educational curricula.
Assessment of reinforced embankment on soft soil with PET and PP Geotextile

A parametric study is carried out to investigate the applicability of limit equilibrium method for analyzing reinforced embankment on soft soil in this paper. The effect of vertical spacing of geotextile layers, slope inclination, and tensile strength of PET (Polyester) and PP (Polypropylene) geotextile behavior on reinforced flyash and clay mixed embankment, over a soft clay layer is studied. For present investigation study, a 8 m high embankment with 20 m crest width and slopes of 58°, 64°, 72°, and 78° are considered. Analysis was performed using the GEO5 – slope stability software version 12 after modeling the above standard geometry. Results divulge that use of full length of geotextile covering whole width of embankment can increase factor of safety (F.S) at steeper slope inclination. Also decreasing the slope inclination and vertical spacing of geotextile gives safer designs. From this study it is seen that reinforced embankment with PET geotextile gives economical and safe design, compared to PP geotextile when the creep phenomenon is considered as a governing factor.
Working memory performance differentiated by physical functional capacity in late-adulthood

The aim of this study was to examine whether working memory performance is differentiated by higher and lower physical functional capacities in the elderly. Forty-six healthy, active older males aged 65-75 years were assigned into either a Higher-capacity group (HC group; n = 23) or Lower-capacity group (LC group; n = 23) based on the median split of their distance walked in the 6-min walking test, an assessment tool for physical functional capacity. The Sternberg working memory paradigm was employed to measure working memory performance, where data on reaction times (RT) and response accuracy were collected as performance indices. Results demonstrated that the HC group had faster RT compared with the LC group. No group difference in response accuracy was observed. Overall, the study indicated that working memory performance may be differentiated by physical functional capacity in healthy, active older males.
Variance Ratio Tests of the Random Walk in the BRVM

The hypothesis that a stock market price index follows a random walk is tested for the regional stock market of the West African Economic and Monetary Union called the Bourse R¨¦gionale des Valeurs Mobili¨¨res (BRVM) using the Lo and MacKinlay (1988), the Chow and Denning (1993), and the Wrighti¯s (2000) rank-based variance ratio tests. The tests are applied to daily stock price index over the period January 2, 2002 to December 31, 2004, and all three tests reveals that the null hypothesis of random walk can not be rejected in the BRVM. This result is an indication that the BRVM is weak form efficiency and has various implications for investors and regulators. The first would engage their savings into productive investments opportunities and the second will limit their intervention as securities are fairly priced.
Atomistic calculation of the thickness and temperature dependence of exchange coupling through a dilute magnetic oxide

The exchange coupling of two magnetic layers via a diffuse oxide interlayer is studied with an atomistic spin model. We investigate the effect of magnetic concentration and oxide layer thickness on the effective exchange coupling strength and find an exponential dependence of the coupling strength on the oxide thickness without the need for magnetic pinholes. Furthermore we show that exchange coupling has a strong temperature dependence which is significant for the reversal dynamics during heat assisted magnetic recording.
Automated number plate recognition from low quality video-sequences

The commercially used automated number plate recognition (ANPR) systems constitute a mature technology which relies on dedicated industrial cameras capable of capturing high-quality still images. In contrast, the problem of ANPR from low-quality video sequences has been so far severely under-explored. This thesis proposes a trainable convolutional neural network (CNN) with a novel architecture which can efficiently recognize number plates from low-quality videos of arbitrary length. The proposed network is experimentally shown to outperform several existing approaches dealing with video-sequences, state-of-the-art commercial ANPR system as well as the human ability to recognize number plates from low-resolution images. The second contribution of the thesis is a semi-automatic pipeline which was used to create a novel database containing annotated sequences of challenging low-resolution number plate images. The third contribution is a novel CNN based generator of super-resolution number plate images. The generator translates the input low-resolution image into its high-quality counterpart which preserves the structure of the input and depicts the same string which was previously predicted from a video-sequence.
Modelling of fast neutral Li beams for fusion edge plasma diagnostics

We present an experimental and theoretical study on the modelling of fast Li beams which are used for diagnostics of fusion edge plasmas. The atomic collision database utilized for modelling the Li beam attenuation has been revised and extended by detailed investigations of populations resulting from ion impact excitation. We obtain good agreement between measured and calculated Li(nl) populations for an Li beam passing the edge plasma region of the ASDEX Upgrade tokamak and WENDELSTEIN 7 AS stellarator, respectively, at IPP Garching.
