The role of social capital in fostering entrepreneurship in established organizations

This study investigates social behavior of employees and its effect on entrepreneurial activities. Social capital is a strategic resource available through the network of relationships may be exploited in the direction of organizational and individual objectives. The study posited that this powerful asset may be leveraged in fostering entrepreneurial orientation of employees, which is an antecedent for improving the performance. A developed survey was sent to a selected sample of academic staff in five public univer sities in Victoria. The collected data were subject to statistical analysis and the result was derived. The findings indicated that there is a positive and significant relationship between social behavior and entrepreneurial orientation of academics. The predictability of entrepreneurial activities by social relationships was tested.
IRSL and post-IR IRSL residual doses recorded in modern dust samples from the Chinese Loess Plateau

Using a set of modern/young (0 to about 200 years old) dust samples collected from the Chinese Loess Plateau the bleachability of IRSL measured at 50°C (IR50) and post-IR50 elevated temperature IRSL (measured at 225°C and at 290°C) is investigated by measuring the apparent (residual) doses recorded by these signals. Doses recorded by quartz OSL are used as a reference. Allowing for differences in dose rates it seems that both IRSL and post-IR IRSL signals yield residual doses that are significantly larger than the doses measured in quartz. These residual doses can be largely explained by thermal transfer caused by preheating. Nevertheless, we advise against the use of a low temperature preheat (<200°C) with IR50 to date loess samples because, as has been reported before, the signal appears to be thermally unstable. In general, we conclude that it may not be advisable to apply post-IR IRSL dating to Chinese loess samples where residuals of up to ∼20 Gy are a significant fraction of the total dose. However, these residuals quickly become unimportant when dating older samples, and this is the age range in which post-IR IRSL dating is likely to be most useful.
Taxonomic Probability Matrix for Use With Slowly Growing Mycobacteria

A probability matrix for identification was developed from data derived from a series of cooperative studies of slowly growing mycobacteria. The matrix includes feature frequencies exhibited by 14 numerical taxonomy clusters in 34 tests. The clusters correspond to 13 defined species. The matrix is designed primarily to screen strains either for membership in 1 of the 14 taxa or for exclusion from these taxa and, thus, to determine whether the strains are in need of further characterization. The matrix was used in the analysis of 298 strains. Two related parameters were used as decision thresholds. First, the probability of the most likely taxon must be 99 times greater than that of the second most likely taxon. Second, the absolute likelihood of the strain being in the most likely taxon must be at least 0.01 times that of a “perfect” strain of the taxon. By using these thresholds and additional judgments, 83 strains were found to be appropriate for further study, with a likelihood that 53% of these strains belong to unrepresented taxa.
Advances in Smart Technologies for Structural Health Monitoring of Cable-stayed Bridges

This study deals with the general problem of developing smart technologies for vibration and impedance-based structural health monitoring (SHM) of cable-stayed bridges. The following approaches are implemented to achieve the objective. Firstly, vibration- and impedance-based SHM methods suitable for cable-stayed bridge are briefly outlined. Secondly, smart sensors are designed for vibration- and impedance-based SHM. Thirdly, the practicality of the smart sensor system is evaluated on a real cable-stayed bridge, Hwamyung Bridge in Korea. The system's performance is experimentally analyzed under various cable forces and weather conditions. Finally, the experimental modal parameters are identified by numerical modal analyses of the target bridge. Also, its structural parameters are estimated from the vibration-based structural identification using experimental modal parameters.
Evaluation of the influence of transport and adaptation stress on chosen immune and oxidative parameters and occurrence of respiratory syndrome in feedlot calves

Abstract Immune and oxidative parameters were evaluated as indicators of the influence of stress on the occurrence of respiratory syndrome in feedlot calves. The study was carried out on 60 2 and a half-month-old Simmentaler calves transported at feedlot. Mean daily feed consumption, daily weight gain, and behavioural activity were evaluated. Blood was collected on days 1, 3, 7, 14, 21, and 28 of feedlot. Serum NO ions, lipid peroxidation, acute phase proteins, IgG, and IgM were determined. The calves showed a decrease in feed consumption during the first 7 d of the feedlot. Sporadic stereotypies were noted. NO concentration showed a significant (P < 0.05) increase on days 7 and 14. Concentration of thiobarbituric acid reactive substances (TBARS) increased (P < 0.05) on days 1 and 3. IgM concentration was found to be considerably lower on days 14 and 28. Serum haptoglobin level showed a significant increase in stressed calves on days 1, 3, 7, and 14 of the feedlot. Based on these results, it can be suggested that stressors associated with transport and adaptation to the feedlot induce a stress reaction in calves, resulting in behavioural disorders, reduced weight gain, suppression of the humoral immunity and increased morbidity during the first weeks. These parameters seem to be crucial in evaluating the animals' health and welfare.
Factors influencing consumer behavior relating to the purchase of honey part 2. Product quality and packaging

Abstract Research surveys were conducted from August through December 2011 and March through July 2012, in the regions of Lower Silesia, Opole, Silesia, and Wielkopolska, Poland. Respondents were chosen randomly and a sample of 540 respondents were surveyed. The first aim of this study was to investigate the quality and aesthetic factors expected of honey and its packaging in order to establish their influence on decisions related to the purchase of honey. The second aim was to determine the importance of the aesthetic factors of honey and its packaging in the process of influencing consumer behavior related to the purchase of honey. As many as 78% of respondents said that the honey from a beekeeper was better than that offered in the stores. A large number of respondents, 88.3%, choose honey produced domestically. However, our study showed that for 43.4% of the respondents, packaging and visual features did not affect the purchase of the product. Only for 23% of respondents, the origin of the honey and quality which was guaranteed with certificates were the most important factors taken into account when deciding on the place or form of a honey purchase. The varieties of honey most often indicated by the respondents were: multifloral honey 46.9%, linden honey 42.5%, rapeseed honey 16.2%, and acacia honey 12.8%. The selection of honey varieties was primarily determined by psychological factors, social factors, and only later by convenience of consumption or financial situation.
Low-Fat, Light, and Reduced in Calories: Do These Claims Really Lead to an Increase in Consumption?

Recent experimental research has shown that light, low-fat and other claims that signal low calorie content can increase consumption and hence can be counter-effective. In this article we use detailed data from the Dutch National Food Consumption survey to determine the extent to which this increase in consumption can also occur outside an experimental setting. We investigate consumption of 36 different products, including dairy products, fats, and non-alcoholic beverages. Looking at both the consumption amount in grams per eating occasion and the consumption frequency over a period of two days, we find almost no evidence that more is consumed of “light” variants than of regular variants. For only 5 of the 36 products we find a consistent and significant higher consumption in grams of the “light” variant, while for 8 products, consumption frequency of the “light” variant is significantly higher. Moreover, for almost all of these products, we observe that in terms of calories, still less is consumed of the “light” variant than of the regular variant. We conclude that in real-life non-experimental settings “light” claims do not lead to increased consumption of the “light” products.
Financing the need for infrastructure in WAEMU countries through public debt

This paper proposes an assessment of the non-linear relationship between public deficit and public investment in debt situation. We use an endogenous growth model, with productive public spending, that we test empirically using the interaction model of Brambor and al. (2006), over the period 1980-2017, in WAEMU countries. The results of the estimates show a change in the regime of the relationship between public investment and public deficit for public debt level equal to 75% of GDP. When public debt is below this threshold, any increase in the deficit has an expansive effect on public infrastructure spending. When public debt is above the threshold of 75% of GDP, an increase in the deficit has a recessive effect on public investment.
Studies on Haematological and Serum Biochemical Characteristics of Weaner Rabbits Fed Different Levels of Wild Sunflower ( Tithonia diversifolia Hemsl A. Gray) Leaf- Blood Meal Mixture

A 59 day -feeding trial involving thirty-two, 5-& weeks old, weaner rabbits of mixed breeds and sex with initial weight of between 594 and 608g was conducted to examine the effect of feeding different levels of wild sunflower leaf- blood meal mixture (WSFLBM) as a iron- conventional feedstuff on the haematological and serum biochemical indices of weaner rabbits. The rabbits were allocated into 4 treatment groups of 8 rabbits per group. Each rabbit served as a replicate in a completely randomized design experiment. The four treatment groups had diets containing WSFLBld at 0,5. 10 and 20% dietary inclusion levels. All the haematological parameters evaluated: White blood cell count(WBC), Red blood cell count(RBC'), Mean corpuscular haemoglobin concentration (MCHC), Mean corpuscular haemoglobin (MCH), Mean corpuscular volume(MCV)were not significantly (P > 0.05) affected by the inclusion of WSFLBM. Significant influences were not observed for total protein, albumin, globulin and alkaline phosphatase. However, the serum biochemical indices evaluated, showed that cholesterol, SGPT and SCOT were significantly (P < 0.05) affected as the level of WSFLBM increased. It was concluded based on data from WBC, RBC, MCV, MCH MCHC and those from serum biochemical indices evaluated that wild sunflower leaf- blood meal mixture could be incorporated up to 20% level in weaner rabbit ration.
Effects of age and sex on meat quality of Turkish native geese raised under a free-range system.

Summary This study was conducted to determine the effects of sex and age on meat quality characteristics of Turkish native geese raised under a free-range system. The range of least squares means for age and sex subgroups in terms of ultimate pH, water holding capacity (WHC), drip loss (DL), cooking loss (CL) and Warner-Bratzler shear force (SF) were 5.74-5.88, 8.99-9.69%, 3.36-3.63%, 27.67-29.97% and 3.15-3.38 kg/cm2, respectively. Least squares means for colour characteristics of breast skin were 61.97-62.60 for lightness (L*), 5.11-5.84 for redness (a*) and 11.18-12.26 for yellowness (b*) according to age and sex groups. Colour variables of breast meat were 40.15-40.59 for L*, 12.30-13.61 for a* and 0.83-1.16 for b* parameters. While the effect of age on breast meat quality characteristics were not significant (P>0.05), sex affected on ultimate pH and a* parameter significantly ( P 0.05).
The Impact of Value Added of Intellectual Capital to Firms Profitability and Productivity

The changes in business environment which lead by globalization have force the companies to enhance their competitiveness. Previous researches have found that intellectual capital (IC), as one of intangible assets, enable the companies to have value added for profit creation. This research will examine the value added of intellectual capital to firms#65533 profitability, Asset Turnover ratio (ATO) and employee productivity. The object of this research is banking companies listed in Indonesian Stock Exchange (IDX) over the period of 2007 to 2011. The banking firm is a unique industry since, as a service industry this sector has high dependency on the intellectuality of its human resources. Using regression analysis, this study has found that value added intellectual capital (VAIC (TM) ) is important in developing firm#65533s profitability and employee productivity. The insignificant influence of intellectual capital is found its relationship to assets turnover. Capital employed efficieny, as the variable of VAIC, is the most consistent variable in influencing profitability, employee productivity and assets turnover.
Black-capped chickadee dawn choruses are interactive communication networks

Summary The dawn chorus of songbirds provides an ideal opportunity to study communication networks because multiple singers are within signalling range of each other, permitting eavesdropping by both males and females. Using an Acoustic Location System, we examined the dawn chorus singing behaviour of male black-capped chickadees (Poecile atricapillus )i n 15 neighbourhoods to determine whether singing behaviour is consistent with the communication network model. We calculated levels of frequency matching for 19 focal males and all of their neighbours. The observed level of frequency matching was greater than expected by chance. All males were involved in multi-way matching at dawn and often matched two or three neighbours simultaneously. The identity of individuals involved in three-way matches was related to both previous winter-flock membership and the relative dominance rank of the interacting males. We show that male black-capped chickadee dawn choruses are interactive communication networks where males are involved in high levels of matching with neighbours, and they match multiple individuals both simultaneously and sequentially. Additionally, the existence of multi-way matching and the identities of individuals involved suggest that individual males may eavesdrop at dawn. This is the first study to quantify network communication during the dawn chorus in multiple neighbourhoods.
Structural Social Capital and Economic Performance: Findings of Empirical Farm Data in the Czech Republic

With the change of the political regime in Central and Eastern Europe, both managers of corporate farms and newly established private farmers had to adjust to the rules of the market economy. Among both groups, some are economically more successful than others. In general, a varying adoption of production factors is identified as being of influence. Whether their ability to collaborate with other farms is an additional factor which has been discussed under the concept of social capital since quite some time will be analyzed in this paper. Based on the findings of a survey among a sample of 62 farms in the Czech Republic it can be shown by adopting factor and multiple regression analysis that social capital is indeed a significant factor determining the level of agricultural income.
Three-dimensional photonic crystals based on macroporous silicon with modulated pore diameter

We report on the fabrication and optical characterization of a three-dimensional (3D) photonic crystal on the basis of macroporous silicon. The structure consists of a 2D array of air pores in silicon whose diameter is varied (modulated) periodically with depth. The bandstructure of the resulting 3D hexagonal photonic crystal is calculated and compared with transmission measurements. The described structure allows to adjust the dispersion relation along the pore axis almost independently from the dispersion relation in the plane perpendicular to the pore axis.

REFLECTANCE COMPARISON BETWEEN SCIAMACHY AND A RADIATIVE TRANSFER CODE IN THE UV

SCIAMACHY, onboard Envisat, is an Earth-monitoring spectrometer over the wavelength range 240–2400 nm. We compare its reflectance measurements in the UV with calculations by a polarised radiative transfer code for a cloud-free state over the Sahara desert. The SCIAMACHY reflectance between 240 and 400 nm is found to be too low by about 15–25%. The estimated error on this is less than 5%. The comparison method we present here can also be helpful for the in-flight calibration of other UV satellite spectrometers (like OMI, or GOME-2).
Integrated waveguide device for picosecond pulse amplification and spectral shaping

Pulsed lasers with a coherent broad optical spectrum are attractive sources for use in arbitrary waveform generators [1], dense wavelength division multiplexing systems, optical code-division multiple-access (O-CDMA) systems [2] and frequency comb generation. Such systems can be realized on a single photonic integrated circuit when semiconductor mode-locked lasers (MLLs) are used as the pulsed source. Nowadays monolithic MLLs are able to produce pulses with durations down to 1-2ps, having a corresponding spectral width of up to 2nm [3]. By changing the design or operating conditions the spectrum can be broadened, leading to non-transform limited pulses [4,5]. To increase the optical bandwidth of picosecond pulses further, amplification and highly non-linear fibers are often used. In a photonic integrated circuit a semiconductor optical amplifier (SOA) is a possible option, though at the expense of increasing the noise in a system and the broadening that can be achieved is limited. In this paper we present our IRIS device [6] which we have designed to add bandwidth to an optical picosecond pulse, for applications as mentioned above. We compare the performance of a number of configurations of the IRIS device with an SOA of the same length, both theoretically and experimentally.
BJRS BRAZILIAN JOURNAL OF RADIATION SCENCES

In the clinical practice PET imaging provides semi-quantitative information about metabolic activities in human body, using the Standardized Uptake Value (SUV). The SUV scale, by itself, does not to establish thresholds between benign and malignant uptake in high-level analyses, such as pattern recognition. The objective of this work is to investigate in PET image volume with high-uptake regions, two additional descriptors, besides the SUV measurements: the amount of information given by the Hartley function (IHartley) and its expected value, the Shannon entropy (H). To estimate these descriptors, two models of the probability distribution were obtained from a high-uptake region of interest (ROI): (i) the normalized grayscale histogram from SUV intensity levels (Pi), which provides global IHG and HG; and (ii) the normalized gray level co-occurrence matrix (GLCM) of these graylevels Vieira, I.F. et. al. ● Braz. J. Rad. Sci. ● 2015 2 International Joint Conference RADIO 2014 Gramado, RS, Brazil, August 26-29, 2014 SOCIEDADE BRASILEIRA DE PROTEÇÃO RADIOLÓGICA SBPR (Pg,k) at the same range, which provides local IHL and HL. The beginning results have shown that for the ROI (12x12 pixels) and for mean SUV ranging of 6.6213±0. 5196 g/ml, with SUVMax = 14,7372 g/ml, the global entropy (2,3778±0,0364) has a higher average uncertainty that local entropy (2,2069±0,0758), with a confidence interval of 99.95% (pvalue < 0,05%). This can be explained by analysing the sample from the amount of information, IHartley, noting that on average local Pg,k provides up to 90,55±9,18% more information when compared to the amount of information given by global Pi. Therefore, these initial results suggest that, for build algorithms for PET image segmentations using threshold based in entropy measures, it is more appropriate to use a distribution functions estimator which considers the local information of the pixels intensities. The main application of this approach will be for, among other things, to construct pathological phantoms from PET images for dosimetry applications.
Environmental Controls on the Diversity, Growth, and Activity of Ammonia-Oxidizing Microorganisms in Temperate Forest Soils

The goal of my dissertation research was to investigate the structure and function of ammonia-oxidizing microbial communities in temperate forest soils. Accomplishing this goal required a hybrid approach: I used modern molecular biology techniques alongside soil biogeochemical measurements and framed my research using ecological theory largely developed in plant systems. All of my field work was done at Coweeta Hydrologic Laboratory, a Forest Service Station and Long Term Ecological Research Site near Otto, NC. Watershed-level land use manipulations have been performed at Coweeta since the 1930s, including clear-cutting, fertilizing, liming, burning, grazing by cattle, and replanting entire watersheds in white pine. While these treatments were originally imposed to assess the effects of land use on water yield, they have resulted in changes in soil characteristics as well. Working at Coweeta has therefore allowed me to sample ammonia-oxidizer communities across a gradient of soil variables, such as pH and nitrogen (N) availability, within the geographically-constrained area of the Coweeta Basin. First, I used amplicon-based pyrosequencing to independently assess the diversity of ammonia-oxidizing archaea (AOA) and bacteria (AOB) at several sites within Coweeta. I found that AOA and AOB diversity were a function of both resource availability (i.e. N availability) and environmental harshness (i.e. soil pH) in line with general ecological theory developed for plant systems by Tilman and Grime, respectively. Next, I tested whether AOA and AOB were substrate or nutrient limited in this system by adding either N or a nutrient solution containing both potassium and phosphorus to soil incubations and assessing the growth response of AOA and AOB using quantitative polymerase chain reaction (qPCR). I found strong evidence for substrate limitation by AOB and a marginally-significant positive effect of nutrient
