LOCATION CHOICE DETERMINANTS OF FOREIGN AFFILIATES IN DEVELOPING COUNTRIES : EVIDENCE FROM SPANISH MNEs

In this paper, we examine how different host country characteristics affect the location decision of Spanish MNEs in developing and transition countries, paying particular attention to the sectoral composition of FDI between manufactures and services. The study focusses on a broad firm-level dataset of 4,177 Spanish affiliates established in 52 countries during the period 1990 to 2010. The results, obtained by the estimation of a set of discrete choice models, provide empirical support to the predictions of the recent FDI literature, suggesting that the Spanish MNEs location choice is driven by both market-seeking and efficiency-seeking factors. Market potential and agglomeration forces are clearly presented in the location decision of Spanish multinational firms in developing economies, although the intensity of agglomeration externalities relies on both the sort of activity and the nationality of competitors. Our findings also confirm the existence of differences between manufactures and services in other local factors, such as human capital or per capita income. The macroeconomic stability and the quality of infrastructures also appear to influence the location of FDI in these economies, what corroborates the importance of local conditions for the investment decisions. Finally, the outcomes from the nested and mixed logit models reveal that MNEs investing in services are risk adverse and contemplate those recipient countries with similar business environments as closest substitutes.
Building the Evolvable Web Encyclopedia by Information-gathering Agents 藤井 敦

The World Wide Web, which contains a surprisingly much volume of up-to-date information, is a promising source to obtain encyclopedic knowledge for new and technical terms. In this project, we developed a system (software agents) to produce encyclopedias from the Web. Our system first searches the Web for pages containing a term in question, and analyzes HTML layout of pages to extract paragraph-style fragments that describe the term. Finally, only high-quality fragments are selected and organized based on domains in a resultant encyclopedia. We used our system to build an encyclopedia including approximately 200,000 entries. We also performed a number of experiments, in which human assessors and a large number of anonymous subjects evaluated the quality of our encyclopedia. The results showed that our project potentially rivals existing hand-crafted encyclopedias and Web search services.
ACOUSTIC BEAMFORMING BY NON-SYNCHRONOUS MICROPHONE ARRAY MEASUREMENTS

Acoustic beamforming consists in measuring the sound field by the microphone array and infers the source strength in conjunction with the propagation model. A fundamental limitation of acoustic beamforming is determined by the aperture size of the array and the microphone density. In order to extend the working frequency range of conventional phased array beamforming, the sound sources are scanned by moving sequentially a small prototype array, resulting in a large array and high microphone density measurements, which is referred to as non-synchronous measurements beamforming. The main issue of nonsynchronous measurements beamforming is that the phase relationships between consecutive snapshots of non-synchronous measurements are missing and result in missing entries in the spectral matrix, however, complete spectral matrix information is crucial for high quality image of beamforming. Thus, non-synchronous measurements beamforming boils down to a spectral matrix completion problem which is modeled by a structured low rank model and solved by designed fast iteration algorithm. In particular, the structured low rank model is constructed by two ingredients: (1) the low rank property of the spectral matrix and (2) the continuity of the acoustic field. The simulation results show the nonsynchronous measurements beamforming extended the working frequency range of given small phased array from 2−2.8 kHz to 1.6−4.5 kHz with only 9 times non-synchronous measurements.
Challenges of Low-to-Moderate Seismicity in India

India is a vast country that is growing even faster. Particularly over the last decade, there has been a sudden spurt in the construction activity in the country, especially in the large low-to-moderate seismic regions of the country. But, no systems are in place to regulate these massive constructions to ensure seismic safety. This paper raises the challenges in the current practice and provides measures to overcome them. In particular, the paper argues for separate provisions for the design and construction of structures in low-tomoderate seismic regions.
A Summary of the TribeFlow Model for Music Discovery Applications

How can we determine which artist a given user will listen to next? Is it possible to create interpretable representations of listening trajectories? In this paper, we present an overview of a recently proposed method, called TribeFlow, developed to tackle questions like these. In music streaming datasets, TribeFlow has been shown to be more accurate than other approaches. Also, TribeFlow is able to represent user behavior in an interpretable and probabilistic latent space.
Regulatory T cells constrain the TCR repertoire of antigen-stimulated conventional CD 4 T cells

To analyze the potential role of Tregs in controlling the TCR repertoire breadth to a non-self-antigen, a TCRb transgenic mouse model (EF4.1) expressing a limited, yet polyclonal naïve T-cell repertoire was used. The response of EF4.1 mice to an I-Abassociated epitope of the F-MuLV envelope protein is dominated by clones expressing a Va2 gene segment, thus allowing a comprehensive analysis of the TCRa repertoire in a relatively large cohort of mice. Control and Treg-depleted EF4.1 mice were immunized, and the extent of the Va2-bearing, antigen-specific TCR repertoire was characterized by high-throughput sequencing and spectratyping analysis. In addition to increased clonal expansion and acquisition of effector functions, Treg depletion led to the expression of a more diverse TCR repertoire comprising several private clonotypes rarely observed in control mice or in the pre-immune repertoire. Injection of anti-CD86 antibodies in vivo led to a strong reduction in TCR diversity, suggesting that Tregs may influence TCR repertoire diversity by modulating costimulatory molecule availability. Collectively, these studies illustrate an additional mechanism whereby Tregs control the immune response to non-self-antigens.
Effects of Media Use on Mental Health Among Adolescents and Emerging Adults

Media, such as the use of the internet and watching television, allows for quick communication between people, but overexposure to such media is correlated with social anxiety and clinical depression (Becker, Alzahabi, & Hopwood, 2013; Dalbudak et al., 2013; Dittmar, 1994; McNaughton-Cassill, 2001). Media usage is pervasive in our society, especially among adolescents and college students (Dittmar, 1994; Rideout, Foehr, & Roberts, 2010; Romer, Bagdasarov, & More, 2013). Symptoms of these mental illnesses are correlated with all forms of media, and can be influenced by the content of the media as well (Madan, Mrug, & Wright, 2013). Excess use of such media among adolescents and college students correlates with this rising surge of mental illnesses. This literature review discusses (a) the correlation between overexposure to media and depression and anxiety, (b) the content of such media and its effects on behavior, and (c) preventative treatments to such illnesses due to media.

Management of Meloidogyne incognita on cowpea ( Vigna unguiculata L . Walp ) with three powdered Aloe species leaves

In vitro nematicidal efficacy of some Aloe species on Meloidogyne incognita are known, but their effectiveness in the management of nematodes of field crops is scant. Pot and field experiments were laid out in completely randomized design and randomized complete block design, respectively, to determine the effects of three powdered Aloe species leaves of Aloe keayi (AKY), Aloe succrotina (AST), and Aloe vera (AVR) compared with carbofuran in the management of M. incognita on cowpea. Two-week old cowpea seedlings were inoculated with 10,000 eggs of M. incognita. A week after inoculation, powdered leaves of AKY, AST, AVR at 20 kg/ha, 40 kg/ha, 60 kg/ha, 80 kg/ha and carbofuran at 1 kg and 2 kg a.i/ha were applied. Data were collected on Vegetative Growth (VG), Grain Yield (GY), Gall Index (GI), Nematode Population (NP), and Reproductive Factor (RF). Data were analyzed using standard procedures. Carbofuran at 2 kg a.i/ha, A. keayi at 80 kg/ha, A. vera at 80 kg/ha, and A. succrotina improved VG by 185.2%, 146.3%, 127%, and 84.5%, respectively. Carbofuran-treated plants at 2 kg a.i/ha, AKY at 80 kg/ha, carbofuran at 1 kg a.i/ha, AVR at 80 kg/ha and AST at 80 kg/ha improved cowpea yield by 317.9%, 296.8%, 253.3% and 235.7%, respectively. All treated plants with carbofuran and powdered Aloe leaves reduced GI, NP and RF, but AKY at 80 kg/ha compared effectively with carbofuran at 2 kg a.i/ha. Powdered AKY, AVR and AST leaves at rates of 40-80 kg/ha can be used to manage M. incognita on cowpea, but best in A. keayi treatments at 80 kg/ha.
Improved methods of modification of spectral shape for speech under the noisy environment

This paper describes the spectral modification method for the signals polluted with noise. Modification of the shape of spectral envelopes is effective for the enhancement of speech. However, there are some problems of the stableness of the modified envelopes. In this paper,, two kinds of threshold functions are presented as the improvement of the stability of the intersection point between threshold functions. These functions are used step by step and plural valleys are added to noisy spectral envelopes. The position of the bottom of valleys is controlled using other function. Next, non-linear threshold functions are defined instead of the linear functions used above. The aim of this function is the improvement of the illegal valleys obtained on high frequency domain. Several functions are defined and evaluated using the performance of the digits recognition system. Using these functions, the recognition rate improved comparing with conventional modification methods. The effect of these functions is remarkable in case that the environment is poor.

Graz – Austria DETECTION OF AUDIBLE RESONANCES

The paper discusses the problem of the detection of audible resonances. The basic psychoacoustic researches have shown that the threshold of resonance detection can be classified by resonance level and Q-factor. In this work a third criteria is introduced. It is the energy of the resonance. By analyzing the influence of resonances on the frequency response and group delay, it is shown that it is almost impossible to detect resonances that are near the threshold of audibility. Finally, three common techniques for resonance detection are compared: the cumulative spectral decay, the shaped sine burst decay and the transfer function pole–zero identification. In the conclusion suggestions for the use of the particular method are given.
Panning with Height on 2 , 3 , and 4 Loudspeakers

A phantom source is typically created by two loudspeakers playing the same signal. In the horizontal plane, phantom source localization can be explained by binaural localization cues, i.e. the inter-aural time and level differences. Three-dimensional sound systems based on amplitude panning such as Vector-Base Amplitude Panning (VBAP) and Ambisonics assume the existence of vertical phantom sources. Obviously, vertical phantom sources cannot be explained by inter-aural differences, since cues that decode elevation are spectral modifications caused by pinna, head, and torso. Indeed studies exist which imply that localization of vertical phantom sources for multichannel loudspeaker arrays is possible, even though the localization is intersubjective and therefore phantom sources are localized individually. The ICSA 2011 was the starting point for a discussion that raised the question if and how such localization works. Since then, studies were presented that confirm the existence of amplitude-panned phantom sources created by two loudspeakers placed in the median plane. This article examines the localization of amplitude-panned phantom sources created by horizontal and vertical loudspeaker pairs, as well as loudspeaker triangles and rectangles. The results are compared to existing vector models yielding a conclusive proposal for three-dimensional amplitude panning.
Influence of Adiponectin Gene Polymorphisms on Adiponectin Level and Insulin Resistance in Non-Diabetic Obese Egyptians

We investigated potential association of adiponectin gene +45T>G and +276G>T single nucleotide polymorphisms (SNPs) with circulating adiponectin, insulin resistance, markers of obesity, systolic and diastolic blood pressure in non-diabetic obese Egyptians. The study included 318 subjects (126 children and 192 adults). Serum total adiponectin, body composition variables, fasting glucose, lipid profile parameters and HOMA-IR were assayed. Genotyping of adiponectin gene at +45 and +276 were analyzed by Real-Time PCR in 155 subjects. Genotyping results showed that at position +45, all subjects were homozygous for the common T allele. At position +276, 30.6% were homozygous for the common G allele, 12.6% were heterozygous for T allele, and 56.5% were homozygous for T allele. In adults, +276 T/G and T/T genotypes were associated with higher LDL and serum adiponectin levels, but that was not statistically significant. No significant association between the +276G>T SNP and serum adiponectin, HOMA-IR or any of obesity markers were found in either pediatric or adult subjects. In conclusion, adiponectin gene +45 and +276 SNPs are not associated with serum adiponectin, IR, and markers of obesity in non diabetic obese Egyptians.
Public Relations Performance for Promoting Italian Wines in Foreign Countries

The promotion activities of Italian wines have been increased, especially after the 2008 reform of EU wine policy where actions for promoting wine in third countries have been encouraged and financially supported. Accordingly, the Federdoc (Italian Confederation of Voluntary Associations for the protection of denomination origin wines) supports promotional projects in foreign countries both within and outside Europe. These actions are mostly public relations (PR) activities such as press conferences, tasting sessions and courses, consumer surveys. Recently, an experimental PR activity, namely Top of the Top, has been started and it consists of a joint promotional activity involving Italian high quality wines and “salami”, a specialty Italian sausage enjoying the UE protected denomination of origin. This promotional experiment, focused on food pairing wines, is aimed to: i) enrich the appeal of Italian wines through a joint tasting a specialty food; ii) educate consumers in wine pairing food experience; iii) take advantage of promotional synergies between wine and food; iv) improve the knowledge and appreciation of Italian gastronomy. Studies on food promotion on international markets may be useful in designing wine promotion campaigns at the international level. Some authors have shown that local country’s features affect the consumer perception on products having strong regional features (Bilkey and Nes, 1982; Romeo and Roth, 1992; Maheswaran, 1994). Other researchers argue that when regional communication is managed at the country level (O'Shaughnessy and O'Shaughnessy, 2000; Gilmore, 2000; Endzina and Luneva, 2004; Olins, 2002) positive effects may be shown as an increase of exports, a growth of tourism, an better attraction of foreign investments, etc. (Paoli, 1999; Van Ham, 2000; Latusi, 2002). Accordingly, the wine promotion may be more efficient when it is focused on regional wines (Schamel, 2009) and it is managed at regional/country level. This paper evaluates factors affecting the appreciation of wines with Geographical Indication (GI) by European consumers, i.e., to what extend the design of promotional actions can impact the consumer’s awareness and perception while encouraging the consumption of wines with GI in different European market . Specifically, well-known PR activities focused on wine only (tasting sessions and courses) are compared winefood ones. Data have been collected through survey questionnaires where information about wine tasting, sensory satisfaction and preferences about Italian wine have been collected together with socio-demographical aspects of foreign users. The sample survey collects preferences of wine market operators in European countries. This work is actually an extension of a previous study mostly focused on measuring the Customer Based Brand Equity (CBBE) model through PR activities (tasting course and knowledge of Italian wines) (Barisan et al., 2015). By mean of a decision-tree methodology, the variables that segment potential consumers of wine with GI are determined (Biggs et al., 1991).
Application for Automatic Measuring of Objects in Augmented Reality

This article describes the technology for automatic measurement of overall dimensions of a generic object using a commercially available mobile phone. The user only has to go around the measured object and scan it by the mobile phone’s camera. The measurement uses computer vision algorithms for scene reconstruction in order to obtain the object’s point cloud. This paper proposes algorithms for processing the point cloud and for estimating the dimensions of the object. It focuses on collecting and filtering points where the biggest challenge is to recognize and separate points belonging to the measured object from the rest. Proposed algorithms were tested on an implemented Android application using ARCore technology. The result of measurement on a cuboid object had the error about 1cm. An object with other shapes achieves measurement error from 3 to 5cm. The measurement error was independent on object size. This implies that the algorithm is more accurate for larger objects with the shape approaching cuboid.
Airborne Visual Tracking and Re-identification & Obstacle Avoidance Using Deep Reinforcement Learning for UAV ’ s Kunal Saini

Visual tracking and person re-identification has gathered a lot of attention in computer vision due to its challenging nature and importance in surveillance applications. In this work, we explore the on-board visual tracking and re-identification of person from moving camera such as a drone. We first detect the humans in the scene, then re-identify potential target and then track. In order to achieve real time tracking, we use Kernelized Correlation Filter (KCF) tracker. To perform long term tracking, we apply re-identification algorithm using deep 3DConvNet. The 3D ConvNet model is reliable in learning the spatio-temporal features with high discriminative power. We develop an android application to realize this system. The application receives frames as input in real time and transmits roll, pitch and vertical upthrust instructions to drone to follow the object being tracked. In addition, our system can handshake with multiple drones and transfer the tasks between them. Our system is fully autonomous In an extreme surveillance scenario, we need obstacle avoidances for drone following the target. To this end, we detect an obstacle and perform actions to avoid it by using deep reinforcement learning. (The algorithm is currently being trained and we expect the results to be obtained before the BTP presentation)
Comparative study of link analysis web page ranking algorithms based on weights of links to extract pertinent links

Ranking is a key factor meant for information retrieval. The web is a huge set of pages to provide an unlimited source of information, which consist of myriad hyperlinks. Search engine database includes the huge quantity of web pages so the ranking of web page is a crucial for satisfying the user requirements. Hypertext Induced Topic Search (HITs) computes hubs and authority scores and Page rank algorithm computes the rank of particular web page. In this paper, the analysis of the significance of web page is compared by utilizing ranking algorithms. The modified weighted HITs(WHITs) algorithm is proposed and its superiority has been compared with existing algorithms like Hypertext Induced Topic Search (HITs), Page Rank, Norm (p) and sNorm (p) to help the search engine to extract a pertinent and valuable link. The algorithms are tested over various short term queries.
