Papers in Evolutionary Economic Geography # 11 . 02 The Dynamics of the Inventor Network in German Biotechnology : Geographical Proximity versus Triadic Closure

Economic geography has developed a stronghold analysing how geography impacts innovation. Yet, despite increased interest in networks, a critical assessment of the role of geography in the evolution of networks is still lacking. This paper juxtaposes geographical proximity with the network of prior ties as alternative mechanisms for tie formation. Analysing the evolution of inventor networks in German biotechnology, the paper theoretically argues and empirically demonstrates that as the technological regime of an industry changes over time inventors increasingly rely on network resources by forming links to partners of partners, whilst the direct impact of geographical proximity on tie formation decreases. K eywords: network evolution, geographical proximity, triadic closure, inventor networks JE L codes: D85, L14, L65, R11 Acknowledgements: An earlier version of this paper was published as a chapter in my PhD thesis at the Department of Economic Geography at Utrecht University.

COMPARATIVE ANALYSIS OF THE EU-27 COUNTRIES LABOUR MARKETS' CONVERGENCE

Convergence is one of the most developing research fields in the frameworks of economic growth's theory. The degree of real convergence has impact on projecting and management of relevant economic and regional policy in the EU. The empirical researches conducted by authors demonstrate that the speed of δ-convergence is low. In 1999-2007 we found δ-convergence in unemployment rates between EU regions NUTS 2, but in 2008-2009 data indicated divergence in regional unemployment rates in EU–27. In conducted analysis only the β-convergence of regional unemployment rates is significant and negative. This shows a convergence process where regions NUTS 2 in EU-27 with higher unemployment rates catch-up on the other ones with lower unemployment rates. Analysies of β-convergence indicate that within the period 1999–2009 the dispersion of labour productivity, labour force participation rates, employment rates between regions NUTS 2 in EU-27 was reduced. However, this relationship was not statistically significant. DOI: http://dx.doi. org/10.5755/j01.em. 17.1. 2270
Exploring the Impacts of Food Technology Beliefs, Evaluations, and Media Consumption on Attitudes Toward Nanofood in Singapore

This paper aims to explore factors influencing people’s attitudes toward nanofood in Singapore. Drawing on expectancy-value theories, this paper conducted a web-based survey (N=1,001) to measure the influences of beliefs of food technology, evaluations of food naturalness, and media consumption about food safety on attitudes toward nanofood and willingness to purchase nanofood products. Results suggested that attitudes toward nanofood are directly shaped by beliefs of food technology, whose influence is partially mediated by media consumption. Attitudes toward nanofood were also positively related to willingness to purchase nanofood. However, our study found no significant effect of food naturalness evaluations on attitudes toward nanofood. This paper helps to elucidate the significance of favorable perceptions of food technology and informative media messages in encouraging positive attitudes toward nanofood.

Properties of high heliolatitude solar energetic particle events and constraints on models of acceleration and propagation

We analyse 9 large solar energetic particle (SEP) events detected by the Ulysses spacecraft at high heliolatitudes during the recent solar maximum polar passes. Properties of time intensity profiles from the Ulysses/COSPIN instrument are compared with those measured by SOHO/COSTEP and Wind/3DP near Earth. We find that onset times and times to maximum at high latitude are delayed compared to in‐ecliptic values. We show that the parameter which best orders these characteristics of time profiles is the difference in latitude between the associated flare and the spacecraft. We find that the presence of a shock is not necessary for the establishing of near equal intensities at Ulysses and in the ecliptic during the decay phase. The model of SEP acceleration by coronal mass ejection driven shocks does not appear to account for our observations, which would more easily be explained by particle diffusion across the interplanetary magnetic field.
Feed substitution and economies of scale in Irish beef production systems

We use a short-run translog cost function to model Irish beef production over the period 2000-2011. Similar to other countries Irish beef farmers operate in various production systems with many farmers specializing in calf rearing, and other farmers specializing in beef fattening or other production systems. In order to identify potential technological differences and differences in scale economies across beef systems we estimate scale economies, own- and cross-price elasticities, and Morishima elasticities of substitution between purchased cattle, purchased feed, home-grown feed and veterinary services for three beef systems. Results suggest that all inputs are substitutes in the cow-calf, calf-to-finish, and other beef systems (store-to-finish and mixed beef systems) whereas extensive economies of scale exist in the cow-calf and calf-to-finish systems. The same trend is observed for other beef systems until 2005 although post-decoupling these systems operate under decreasing returns to scale.
A Social Priming Data Set With Troubling Oddities

ABSTRACT A recent paper by Chatterjee, Rose, and Sinha (2013) reported impressively large “money priming” effects: incidental exposure to concepts relating to cash or credit cards made participants much less generous with their time and money (after cash primes) or much more generous (after credit card primes ). Primes also altered participants’ choices in a word-stem completion task. To explore these effects, we carried out re-analyses of the raw data. A number of strange oddities were brought to light, including a dramatic similarity of the filler word-stem completion responses produced by the 20 subjects who contributed most to the priming effects. We suggest that these oddities undermine the credibility of the paper and require further investigation.
AGE APPROPRIATE HEDONIC SCALES TO MEASURE FOOD PREFERENCES OF YOUNG CHILDREN

Seventy-nine children ages 36-71 months evaluated 2% commercial UHT milk and 2 % commercial pasteurized milk for taste, color and mouthfeel with age appropriate facial hedonic scales with Peryam and Kroll verbal descriptors. Children significantly preferred the pasteurized milk over UHT milk for taste and mouthfeel attributes. Descriptive analysis of milks with an adult trained panel showed a significantly higher cooked note in UHT milk products which may explain the difference in preference. The results also showed that children 36-47 months were able to use the 3-point scale; children 47-59 months the 5-point scale; and children 60-71 months the 7-point scale to score preferences for food. Data transformation for a 0 to 100 point scale provided ease of comparison between age groups. Using the appropriate testing instruments, young children were able to provide valid food preference information.
Tribological Investigation of RBD Palm Olein in Different Sliding Speeds using Pin-on-disk Tribotester

A tribological investigation, in terms of the coeficient of friction and wear resistance of refined, bleached and deodorized palm olein, was conducted using a pin-on-disk tribotester. Palm oil was selected as a candidate due to its superior tribological properties and its large production, which can lead to the mass production of bio-lubricant. The material of the pin and the disk is Titanium (Ti6Al4V). The experiments were conducted following the ASTM G99. The normal load was 9.8 N and the observation time was 1 hour. The sliding speeds were 0.25 m/s and 1 m/s. In this research, only 5 ml of the test lubricant was applied at the beginning of the experiment to investigate the capability of the lubricant to maintain its function. To make sure the lubricant does not subside due to the centrifugal force from the rotating disk; a groove was crafted on the disk. In this research, the coeficient of friction and wear rate were calculated. From the analyses, the coeficient of friction calculated for palm olein was the lowest for both sliding speed conditions, while the wear rate obtained showed that it was eficient lubricating oil at low speed, with a high wear rate at high speed.
Characterization of Temporal Changes in Rainfall, Temperature, Flooding Hazard and Dry Spells over Zambia

Zambian rural communities are vulnerable to climate change because most farmers depend on rainfed agriculture. While efforts on adaptation are being spearheaded, information on the extent of climatic shifts and occurrence of extreme climatic events is limited. Therefore, a study was undertaken to assess changes in climatic variables of rainfall and temperature in Zambia's Agro-ecological zones. The objective of the study was to assess the extent of change in rainfall and temperature and to ascertain the occurrence pattern of extreme climatic events. Daily climatic data records were obtained from the Meteorological department in Zambia. Time series plots were prepared for trend detection in the inter-annual mean rainfall and temperature. A five year moving average was used to obtain the regression equations. Floods were defined to extremes greater than 40 mm in a day and to obtain their return period (T) in year, the cumulative probabilities, F, was transformed by using T=1/(1-F) or T = 100/(100-P) for percentages. A distribution free approach was fitted for estimation of return periods of dry spells in cases where rainfall totals may be zero. Results among the five stations (Choma, Petauke, Mpika, Serenje and Chipepo) considered, indicated that mean temperatures had an increasing trend which was statistically significant only for Choma district. Rainfall trends were variable with some stations (Mpika and Chipepo) showing increasing trends while others (Petauke and Serenje) showing decreasing trends. Floods were frequent in all stations analysed from January to March rather than October to November. Dry spell of 4 days duration were much more frequent than those of 7 and 10 days. Choma was found to be the most susceptible to dry spells while Mpika was the least affected. The study further revealed that the optimal planting widow was the last week of November up to the first week of December for rainfed crop production.
Vibronic dephasing model for coherent-to-incoherent crossover in DNA

In this work we investigate the interplay between coherent and incoherent charge transport in cytosine-guanine (GC) rich DNA molecules. Our objective is to introduce physically grounded approach to dephasing in large molecules and to understand the length dependent charge transport characteristics and especially the crossover from coherent tunneling to incoherent hopping regime at different temperatures. Therefore, we apply the vibronic dephasing model and compare the results to the B\"uttiker probe model which is commonly used to describe decoherence effects in charge transport. Using the full ladder model and simplified 1D model of DNA, we consider molecular junctions with alternating and stacked GC sequences and compare our results to recent experimental measurements.
Effect of administering a diet contamined with fumonisins on the kidneys of wistar rats

Fumonisins (FBs) are mycotoxins produced by Fusarium molds. Several works have shown contamination of maize by this toxin. Fumonisin B1 (FB-1) is found in greatest proportion (about 70%), resistant to several industrialization processes. In that context, the objective of this work was to analyze the effect of administering a diet contaminated with FB-1 on the morphophysiology of the kidneys of 21-day old male Wistar rats. The animals were divided into 2 groups: G0 (with animals receiving feed free of FBs) and G6 (6mg of FB1 kg -1 of feed). The diet was administered during 42 days. After that period, the animals were placed in metabolic cages for urine collection, blood was collected for analysis of plasma creatinine, and the kidneys were fixed and stained with Masson's trichrome. We observed that FB1 administration did not affect feed intake, body weight gain and animal growth. The normal levels of plasma creatinine suggest that the toxin did not lead to glomerular lesion. There was also no change in water intake, osmolarity and excretion of sodium in urine. However, there was a significant increase in urine volume and potassium excretion in urine, with mild tubulointerstitial changes in the outer cortex for the group receiving the mycotoxin.
Determining the flux of methane into Hudson Canyon at the edge of methane clathrate hydrate stability

Methane seeps were investigated in Hudson Canyon, the largest shelf‐break canyon on the northern U.S. Atlantic Margin. The seeps investigated are located at or updip of the nominal limit of methane clathrate hydrate stability. The acoustic identification of bubble streams was used to guide water column sampling in a 32 km2 region within the canyon's thalweg. By incorporating measurements of dissolved methane concentration with methane oxidation rates and current velocity into a steady state box model, the total emission of methane to the water column in this region was estimated to be 12 kmol methane per day (range: 6–24 kmol methane per day). These analyses suggest that the emitted methane is largely retained inside the canyon walls below 300 m water depth, and that it is aerobically oxidized to near completion within the larger extent of Hudson Canyon. Based on estimated methane emissions and measured oxidation rates, the oxidation of this methane to dissolved CO2 is expected to have minimal influences on seawater pH.
IMPULSES AND GROUND REACTION FORCES AT PROGRESSIVE INTENSITIES OF WEIGHTLIFTING VARIATIONS

Five Division-I athletes who routinely performed the hang clean and hang snatch performed a single repetition of each at loads of 50, 60, 70, 80, and 90% of their 1 RM, with 5 minutes rest between each repetition. Movement impulses and peak GRF were evaluated on an AMTI force plate. Two-way ANOVA indicated impulses and peak GRF at 50% 1RM were lower than all other reps (p O.05). These results suggest other variables such as exercise form and movement velocity mediate the amount of impulse and/or force developed.
Young EFL students’ reliance on path-breaking verbs in the use of English argument structure constructions

This study investigates the extent to which young EFL students rely on pathbreaking verbs in the comprehension and production of English argument structure constructions. In a sentence-sorting task, Korean EFL learners in grades 7 and 10 sorted English sentences, which were created by crossing four verbs with four constructions, into same groups according to overall sentence meaning and form. The results showed dominant verb-oriented sorting in grade 7, and more construction-biased sorting in grade 10 when the sentence included a path-breaking verb. In a written production task, Korean EFL students from grades 4 to 7 wrote a book report in English after a 4-week extensive reading program. The results demonstrated the more dominant use of path-breaking verbs in the ditransitive and resultative constructions than in the caused-motion construction. We discuss these findings in terms of usage-based perspectives of constructional learning.
On the Usefulness of the Diebold-Mariano Test in the Selection of Prediction Models: Some Monte Carlo Evidence

Abstract: In evaluating prediction models, many researchers flank comparative ex-ante prediction experiments by significance tests on accuracy improvement, such as the Diebold-Mariano test. We argue that basing the choice of prediction models on such significance tests is problematic, as this practice may favor the null model, usually a simple benchmark. We explore the validity of this argument by extensive Monte Carlo simulations with linear (ARMA) and nonlinear (SETAR) generating processes. For many parameter constellations, we find that utilization of additional significance tests in selecting the forecasting model fails to improve predictive accuracy. ;
SUPERMASSIVE BLACK HOLES AND THEIR HOST SPHEROIDS. II. THE RED AND BLUE SEQUENCE IN THE MBH–M*,SPH DIAGRAM

In our first paper, we performed a detailed (i.e., bulge, disks, bars, spiral arms, rings, halo, nucleus, etc.) decomposition of 66 galaxies, with directly measured black hole masses, MBH, imaged at 3.6 &mgr; m ? > with Spitzer. Our sample is the largest to date and, for the first time, the decompositions were checked for consistency with the galaxy kinematics. We present correlations between MBH and the host spheroid (and galaxy) luminosity, Lsph (and Lgal), and also stellar mass, M * , sph . > While most previous studies have used galaxy samples that were overwhelmingly dominated by high-mass, early-type galaxies, our sample includes 17 spiral galaxies, half of which have M BH < 10 7 M ⊙ , ? > and allows us to better investigate the poorly studied low-mass end of the M BH – M * , sph ? > correlation.

External Debt, Internal Debt and Economic Growth Bound in Nigeria using a Causality Approach

The study examined the causal nexus between external debt, domestic debt and economic growth in Nigeria between 1970 and 2009 using a Vector Autoregressive (VAR) and a Vector Error Correction (VEC) models. The variables used in the study were tested for stationarity using the Augmented Dickey Fuller and Philip Perron test. The result showed that the variables are stationary at first differencing. Co-integration test was also performed and the result revealed the absence of co-integration between domestic debt and economic growth while the result also revealed the presence of co-integration between external debt and economic growth. The co-integration results determined the appropriateness of methodological test for causality. The findings of the VAR model revealed that there is a bi-directional causality between domestic debt and economic growth while that of the VEC model revealed a unidirectional causality from economic growth to external debt in Nigeria. The study recommends that government should rely more on domestic debt in stimulating growth than on external debt.
FORS2/VLT survey of Milky Way globular clusters II. Fe and Mg abundances of 51 Milky Way globular clusters on a homogeneous scale

(ABRIDGED) Globular clusters trace the formation and evolution of the Milky Way and surrounding galaxies, and outline their chemical enrichment history. To accomplish these tasks it is important to have large samples of clusters with homogeneous data and analysis to derive kinematics, chemical abundances, ages and locations. We obtain homogeneous metallicities and alpha-element enhancement for over 800 red giant stars in 51 Galactic bulge, disc, and halo globular clusters that are among the most distant and/or highly reddened in the Galaxy's globular cluster system. We observed R ~ 2000 spectra in the wavelength interval 456-586 nm and applied full spectrum fitting technique. We compared the mean abundances of all clusters with previous work and with field stars. We used the relation between mean metallicity and horizontal branch morphology defined by all clusters to select outliers for discussion. We find our metallicities are comparable to those derived from high-resolution data to within sigma = 0.08 dex over the interval -2.5 < [Fe/H] < 0.0. We also find that the distribution of [Mg/Fe] and [alpha/Fe] with [Fe/H] for the 51 clusters follows the general trend exhibited by field stars. It is the first time that the following clusters have been included in a large sample of homogeneous stellar spectroscopic observations and metallicity derivation: BH 176, Djorg 2, Pal 10, NGC 6426, Lynga 7, and Terzan 8. In particular, only photometric metallicities were available previously for the first three clusters, and the available metallicity for NGC 6426 was based on integrated spectroscopy and photometry. Two other clusters, HP 1 and NGC 6558, are confirmed as candidates for the oldest globular clusters in the Milky Way. The technique used here can also be applied to globular cluster systems in nearby galaxies with current instruments and to distant galaxies with the advent of ELTs.
