Organizational Dynamics and Adoption of Innovations: A Study within the Context of Software Firms in Sri Lanka

This paper examines the effect of organizational dynamics on innovation focus using the residual dominant and emergent theoretical framework (RDE) and the empirical evidence of four case studies. The findings revealed that different types of innovation coexist, but one type becomes dominant over other types at a certain time as the innovation focus is changed in line with the strategic priorities of firms. We found that innovation focus takes the form of product, process, and organizational innovation pattern over time when the firms move from an entrepreneurial organization to a more formal business corporation. More importantly, the RDE framework provides an appropriate lens for practitioners, in identifying the enablers and barriers of innovation.
Bioherbicidal Potential of Leaf-residue of Hyptis suaveolens on the Growth and Physiological Parameters of Parthenium hysterophorus L.

The effects of dry leaf-residues of Hyptis suaveolens L. on the growth and physiological parameters of Parthenium hysterophorus L. was studied in pot culture. Different growth parameters of Parthenium such as size and number of the leaves, height, branches, capitula and seeds/plant were inhibited by leaf residues of H. suaveolens. The amount of chlorophyll and protein was decreased with increased amount of residue. The inhibition in growth parameters of Parthenium hysterophorus was due to decrease in chlorophyll, sugar, protein and lipid contents while organic and amino acids were increased in treatments. The accumulation of organic acid reveals that respiration was hampered in test plant and increase in the amino acids might be the adaptation strategy of Parthenium to avoid environmental stress generated by the allelochemicals present in leaf residues of Hyptis. The decrease in the amount of lipids was proportional to the quantity of dry leaf residues used. The altered physiological parameters result in inhibited growth of Parthenium and the leaf residues of Hyptis suaveolens may be used as potent bioherbicide to control the spread of Parthenium.
Effect of growing season and variety on quality of spring two-rowed barley

Quality of barley consists of precisely defined grain quality attributes (grain weight, grading, grain protein concentration, etc.) and malt quality attributes (extract, viscosity, Kolbach index, etc.). Barley quality attributes are quantitatively inherited and greatly affected by environmental factors such as temperature, available water, nitrogen fertilizer and soil type. The main objective of this study was to determine the effects of genotype and growing conditions (year) on grain and malt quality attributes in barley grown under field conditions in the Pannonian zone. The eight spring two-row barley varieties were studied during a seven growing seasons (1998-2004) on the location Novi Sad (45°20'N, 15°51'E, 86 m asl). The growing season predominantly affected variation of the all studied grain and malt quality attributes of spring barley where its percentage of variance was 35.2%, 20.2%, 32.5%, 25.4%, 30.9%, 31.2%, and 38.5% for grain weight (GW), grading (GRA), grain protein content (GPC), viscosity (VIS), Kolbach index (KOL), Hartong number (HAR) and extract content (EXT), respectively. The interaction of GxE comprised of 28.4%, 64.5%, 38.2%, 54.0%, 39.6%, 41.2% and 23.7% of variation for GW, GRA, GPC, VIS, KOL, HAR and EXT, respectively. The genetic component of variance ranged from 11.1% for GRA to 35.0% for EXT. The heritability was the lowest for GRA-0.54 and the highest for EXT-0.91. Across growing seasons GW ranged from 39.6 to 46.1g, GRA from 76.7 to 91.1%, GPC from 12.1 to 13.5g 100-1g dm, VIS from 1.44 till 1.61m. Ps, KOL from 32.5 to 42,9%, HAR from 31.9 to 45.9VZ 45°C and EXT from 76.3 to 80.3% dm. Out of seven growing seasons EXT was acceptable in four ranging from79.2 to 81.4% dm. Although growing conditions in the Pannonian zone are less favorable for malting barley production in relation to western Europe it does not exclude malting barley production with acceptable quality in the Pannonian zone environments. The varieties Scarlett and Viktor performed quite acceptable quality in the Pannonian zone and may be recommended for commercial production in this region for malt industry.
The "Creative Dolphin" Revisited: What Do Dolphins Do When Asked to Vary their Behavior?

Abstract - The variability of dolphin behavior is evident in their communication, foraging, and play. Dolphins can also vary their behavior when asked to do so by humans. Following the work of Karen Pryor and her colleagues, this ability is commonly referred to as creative behavior, a bit of a misnomer since dolphins need not always create a new behavior to succeed on this task. Nonetheless, when given a task in which success depends on not repeating what one has already done, dolphins are able to remember what they have done and successfully produce a new behavior, sometimes even a completely novel one. In this paper, we report similarities and differences in the performance of three bottlenose dolphins ( Tursiops truncatus ) given such a task, the results highlighting the need for continued investigation of individual differences in cognitive style and performance. Keywords - Innovation, creativity, bottlenose dolphin, Tursiops truncatus , variability, novelty, memory
Histomorphometric Assessment of Bilaterality from the Cadaveric Femurs: Implications for Guidance of Field Practice for Anthropological Age Estimation

Abstract The aim of the present study was to assess bilateral differences in the histomorphometry with osteonal remodeling rate of the femur, which has potential implications for methods of age estimation. Thirty-three femoral samples (18 males and 15 females) were obtained from Korean cadavers and used to analyze the histomorphometric parameters. The thin sections (< 100 mm thick) were prepared by manual grinding. Most of the parameters showed no significant differences between the sides using paired-samples t-tests (p = 0.05), except for the average osteon area (OA) and diameter (OD) of males (p = 0.029 and 0.033, respectively). However, the histomorphometric parameters derived from them eventually did not show significant differences between the sides in both sexes. From the Bland- Altman plot, = 95% of the data points were located within ± 1.96 SD of the mean difference, so all of the histomorphometric parameters showed a high degree of agreement between the sides.
Design of Novel Wideband Monopole Antenna with a Tunable Notched-Band for 2.4 GHz WLAN and UWB Applications

In this article, a novel wideband planar monopole antenna for applications in 2.4GHz WLAN and UWB bands is presented and investigated. The proposed antenna is composed of a gourd-like radiation element fed by a 50Ohm microstrip line and a step-shaped ground plane. A pair of slot lines is etched symmetrically on the ground plane to obtain the 5GHz band-notched characteristic, and the notched band can be tuned. The proposed antenna is successfully simulated, designed, and measured. The measured results agree reasonably with the simulated ones. According to the measured results, the proposed antenna yields a wide bandwidth ranging from 2.2 to 11GHz for VSWR less than 2, except the notched band of 5.1{6.2GHz for 5GHz WLAN. Moreover, it exhibits nearly omnidirectional radiation patterns, stable gain, and small group delay variation across the operation band, which meets the requirements of 2.4GHz WLAN and UWB applications.
TECHNOLOGY, FACTOR ENDOWMENTS, AND SPECIALIZATION IN OECD COUNTRIES: THE ROLE OF VARIABLE CAPITAL UTILIZATION

This paper studies how specialization, measured by industry shares in GDP, is affected by technology and factor endowments. The empirical methodology takes into account variable factor utilization with capital utilization calculated from the consumption of electricity. Estimation results show that ignoring variable capital utilization overstates the effects of technology on specialization. The model is used to explain the differential changes in specialization that occurred in Korea and Turkey between 1975 and 1995. The results show that capital rather than technology accumulation was the most important determinant of this differential.
Balancing London? A Preliminary Investigation of the “Core Cities” and “Northern Way” Spatial Policy Initiatives Using Multi-City Corporate and Commercial Law Firms

This paper reports a preliminary investigation into the economic efficacy of two spatial frameworks—English Core Cities and the Northern Way—recently promoted by national policy makers. We ask whether they are consistent with contemporary economic process in the UK space economy through analyses of commercial multi-city law firms. The latter are treated as an “indicator sector” to define the contemporary UK space economy as practised by law firms. Within this new space of flows, the location strategies of the law firms do confirm the salience of the Northern Way (as trans-Pennine corridor) and Core Cities as part of a larger UK metropolitan space of flows. Conflating the two spatial frameworks leads us to identify hints of a rebalancing of London within a metropolitan UK space. A Manchester polycentric mega-city region is found to be the likely candidate for this role. This finding in no way impinges on London's dominant global role, and we conclude that perhaps mutuality between London and provincial cities is beginning to replace past negative dependency relations.
Evaluation of an operational ocean model configuration at 1 / 12 ◦ spatial resolution for the Indonesian seas ( NEMO 2 . 3 / INDO 12 ) – Part 1 : Ocean physics

INDO12 is a 1/12 regional version of the NEMO physical ocean model covering the whole Indonesian EEZ (Exclusive Economic Zone). It has been developed and is now running every week in the framework of the INDESO (Infrastructure Development of Space Oceanography) project implemented by the Indonesian Ministry of Marine Affairs and Fisheries. The initial hydrographic conditions as well as openboundary conditions are derived from the operational global ocean forecasting system at 1/4 operated by Mercator Océan. Atmospheric forcing fields (3-hourly ECMWF (European Centre for Medium-Range Weather Forecast) analyses) are used to force the regional model. INDO12 is also forced by tidal currents and elevations, and by the inverse barometer effect. The turbulent mixing induced by internal tides is taken into account through a specific parameterisation. In this study we evaluate the model skill through comparisons with various data sets including outputs of the parent model, climatologies, in situ temperature and salinity measurements, and satellite data. The biogeochemical model results assessment is presented in a companion paper (Gutknecht et al., 2015). The simulated and altimeter-derived Eddy Kinetic Energy fields display similar patterns and confirm that tides are a dominant forcing in the area. The volume transport of the Indonesian throughflow (ITF) is in good agreement with the INSTANT estimates while the transport through Luzon Strait is, on average, westward but probably too weak. Compared to satellite data, surface salinity and temperature fields display marked biases in the South China Sea. Significant water mass transformation occurs along the main routes of the ITF and compares well with observations. Vertical mixing is able to modify the South and North Pacific subtropical water-salinity maximum as seen in T –S diagrams. In spite of a few weaknesses, INDO12 proves to be able to provide a very realistic simulation of the ocean circulation and water mass transformation through the Indonesian Archipelago. Work is ongoing to reduce or eliminate the remaining problems in the second INDO12 version.
Psychobiological responses at the beginning and the end of an academic year in teachers

Evidence shows that work stress increases risk of cardiovascular disease. Emotional, cardiovascular and endocrine responses are affected by day-to-day experience. Perceived stress, negative mood, heart rate (HR) and blood pressure (BP) increase in working periods. Cortisol (C) response is not so clear, there being contradictory results. The main purpose is to study stress markers in two working days in teachers. Moreover, we evaluate the role of gender in stress markers in 49 school teachers. Perceived stress, mood, BP, HR, and C were measured at the beginning and at the end of an academic year. Results show that psychological and heart rate responses to a working day were different at the end of the year, increasing, especially in men. BP and C responses descended at the end of the year. In conclusion, an academic year could affect negatively to the emotional state and heart rate of teachers. rcadorf� eePr�`�rante dos jornadas laborales. Ademas se evaluo el papel del genero en la respuesta de estres en 49 profesores. Para ello, se midio la percepcion de estres, el estado de animo, la PA, la FC y el C al inicio y al final de un curso escolar. Los resultados muestran que las respuestas psicologicas y de FC fueron mayores al final de curso, especialmente en hombres. La PA y el C descendieron al final de curso. En conclusion, un curso academico podria afectar negativamente al estado emocional y a los niveles de FC de los profesores.
Estimating the Impact of Trade Facilitation on Global Trade Flows

In this paper we study the role of NTBs on trade flows in South Asia by using a modified global gravity model. We extend the existing literature in several ways: (i) we use improved (high quality) data for bilateral trade flows, tariffs, trade facilitation and other NTB’s; (ii) investigation of the effects of trade facilitation across sectors, with special emphasis on the textile, and automobile and parts, sectors; (iii) incorporation of the estimates into a GTAP-based CGE model to simulate the effects of reducing NTBs on employment by gender, factor earnings across sectors, poverty and income distribution in Bangladesh; (iv) incorporation of robustness checks such as accounting for reverse causality and spurious correlation and also usage of alternative econometric estimation techniques.
Effects of Feeding Wastes from Brassica Species on Growth of Goats and Pesticide/Insecticide Residues in Goat Meat

The effects of feeding Brassica vegetable market wastes on intake, body weight changes and pesticide/insecticide residues in products of goats were evaluated in two experiments. In the first experiment (Exp. 1) 16 goats (Bach Thao, 9 to 10 kg, 3 months old, 9 males and 7 females) were fed four diets with leaves either from cabbage (Brassica oleracea var. capitata), cauliflower (Brassica oleracea var. botrytis) or Chinese cabbage (Brassica campestris subsp. pekinensis) with 30% of Para grass. The control group was fed 100% Para grass. All diets contained soybean waste as a supplement and the experiment lasted for 136 days. In the second experiment (Exp. 2) 24 goats (Bach Thao, 12 to 14 kg, all males) were assigned to three treatments in a completely randomised block design based on initial body weight. The goats were fed cabbage waste supplemented with 200 g or 100 g DM (dry matter) of concentrate. Para grass with 100 g DM concentrate supplementation was used as a control group. The experiment lasted for 90 days and at the end of the study, 12 goats were slaughtered for pesticide/insecticide analysis. Due to low DM content (5.3 and 3.7%, respectively) feed intakes of cabbage and Chinese cabbage groups were lower than those of other groups in the experiment. The highest feed intake and body weight gain was obtained when the goats were fed cauliflower (529 g DM/day and 87.5 g/day, respectively). In Exp. 2 total intake of cabbage and concentrate was similar (484 g and 453 g DM/day) whether the goats were fed 100 or 200 g concentrate/day but lower than that of Para grass and concentrate probably due to the low DM content of the cabbage (5.9%). Crude protein intake (79 g to 86 g/day) and body weight gain (70 g to 88 g/day) was not significantly different between treatments. Adding concentrate consequently resulted in higher DM intake than in Exp. 1 but did not result in any higher growth rate. Three of the pesticide/insecticide residues tested were found in cabbage, Alpha-Cypermethrin, Bassa-Fenobucarb and Dimethoate with levels of 0.175, 0.074 and 0.028 mg/kg fresh cabbage respectively. Weight of livers from goats fed cabbage was about 90 g higher than from goats fed Para grass but no pesticide/herbicide residues were found in meat or liver.
Candidate Classroom Teachers’ Perceptions about being Scientific in the Context of Pseudoscience

The current study, aiming at investigating the perceptions of candidate classroom teachers for being scientific and examining the effect of the intervention comprising particular characteristics of demarcation on those perceptions, was interpretative in nature. Two data sources were utilized in order to determine their pre and post perceptions. Candidates performed poorly in the process of concluding on the status of pseudoscientific knowledge claims. But, after the intervention that based on pre-determined characteristics, the guided participants were seemed to reason more validly and able to evaluate the status of the cases they investigated for being scientific or not.
Behavioural response of eastern wolves (Canis lycaon) to disturbance at homesites and its effects on pup survival

Human disturbance at wolf dens and rendezvous sites (homesites) may have direct effects on pup survival and could result in the alteration of homesite-use characteristics. During a demographic study of eastern wolves (Canis lycaon) in Algonquin Provincial Park, Ontario, we entered active homesites to tag pups with VHF radio transmitters. Homesite attendance and pup survival data collected in 2003–2005 were used to determine (i) the immediate response of wolves to disturbance at homesites, (ii) whether distance moved between homesites was influenced by disturbance, (iii) if pup survival was compromised by researcher disturbance, and (iv) whether reuse in subsequent years differed between disturbed and undisturbed den sites. Packs tended to relocate pups after a disturbance, though we did not detect a difference in distances travelled between natural homesite shifts and those following disturbance. Disturbed homesites were reused in following years at a similar frequency as undisturbed homesites (6 of 15 vs.
Bioaccumulation of Heavy Metals in Clarias gariepinus and Oreochromis spirulus niger from Masinga Reservoir, Kenya

The pollution of aquatic ecosystems with heavy metals has become a worldwide concern. This is because of their ability to bioaccumulate in aquatic organisms and especially in fish which is a source of livelihood for human populations. Therefore, an assessment of heavy metal contamination (Cu, Zn, Pb, Cr and Mn) in two selected food fish species, Clarias gariepinus and Oreochromis spirulus niger in Masinga reservoir was carried out between January 2013 and December 2013. Heavy metal Concentrations were determined using atomic absorption spectrophotometer. The data obtained was analyzed using one way analysis of variance and significant differences accepted at p ≤ 0.05. Post Hoc Turkeys' test was used to separate means. In Clarias gariepinus, mean metal concentrations (mg/kg) in muscles were Cu (0.677 - 0.974), Zn (32.929 - 37.205), Pb (0.643 - 1.078), Cr (0.516 - 0.858) and Mn (0.452 - 0.990). Pb exhibited a significance difference between the sites (p < 0.05). Mean values for heavy metals in Oreochromis spirulus niger (mg/kg) for different sites were Cu (0.515 - 0.782), Zn (29.645 - 37.999), Pb (0.552 - 0.765), Cr (0.559 - 0.791) and Mn (0.183 - 1.480). Only Mn showed significant differences between the sites (p < 0.05). Heavy metal concentrations in the two fish species were lower than World Health Organization (WHO) set limit except for Cr. Results from this study demonstrate the need for an ecosystem approach towards sustainable management of reservoirs. This will curb aquatic pollution which is a health risk for people consuming aquatic resources contaminated with heavy metals.
Micro-optodes in sea ice: A new approach to investigate oxygen dynamics during sea ice formation

Oxygen micro-optodes were used to measure oxygen dynamics directly within the microstructure of sea ice by freezing the sensors into the ice during its formation. The experiment was conducted in a 4 m 3 mesocosm filled with artificial seawater and inoculated with a unialgal culture of the common Antarctic ice diatom Fragilariopsis cylindrus (Bacillariophyceae) to a final chlorophyll a (chl a) concentration of 11 µg l -1 . Ice growth was initiated 7 d after inoculation by reducing the air temperature to -10 ± 2°C and terminated 17 d later. The final ice thickness was 27 cm. One optode was frozen into grease ice and 2 others into the skeletal layer of the growing ice sheet. Increasing oxygen concentrations during ice crystal formation at the water surface and the ice-water interface revealed a strong inclusion of oxygen, which was either physically trapped and/or the result of photosynthesising diatoms. The major portion of oxygen was present as gas bubbles due to super- saturation as a result of increasing salinity and oxygen production by diatoms. An increase in salinity due to a concurrent decrease in ice temperatures during subsequent sea ice development reduced the maximum concentration of dissolved oxygen within brine. Thus, dissolved oxygen concentrations decreased over time, whereas gaseous oxygen was released to the atmosphere and seawater. The sensors are a significant advance on more conventional microelectrodes, because the recordings can be temperature and salinity compensated in order to obtain precise measurements of oxygen dynam- ics with regard to total (dissolved and gaseous) and dissolved oxygen in sea ice. Optodes do not consume oxygen during measurement over a long period under extreme conditions, which is another advantage for long-term deployment in the field.
PREDICTING THE ACOUSTICS OF ANCIENT OPEN-AIR THEATRES: THE IMPORTANCE OF CALCULATION METHODS AND GEOMETRICAL DETAILS

For more than a decade now, computer simulations of sound fields in rooms have been widely adopted in research and for consulting purposes. Most computer simulations are either based on geometrical room acoustics or statistical methods, hereby neglecting diffraction and interference effects. The calculation algorithms in this type of simulations often combine the image-source method and the ray-tracing technique. In this paper, the acoustics of an open-air roman theatre are investigated. This is a special case which sets up a challenge to these prediction methods. The absence of a roof and therefore of a reverberant field, demands high accuracy in predicting the early reflections. The energy dissipates quickly in this type of enclosures and there is little masking effect of the reverberation. The inverse cone shape of these theatres also puts serious limitations to the image-source method, where great areas are in the shadow zone of the mirroring surface. Another aspect that has been shown to give very different results in this case study, is the geometrical detailing of the models. Although it has been pointed out in several studies that models with a limited number of surfaces give more accurate results, in this particular case the opposite is shown to be true. The aim of this paper is to clarify some of the problems that can arise in this type of constructions, and give guidelines for how they can be overcome / avoided. Another objective is to emphasize that room acoustic computer simulations although very useful need careful consideration about the underlying calculation methods.
