The role of market orientation in the business success of the MNC’s foreign subsidiaries

In recent discussions over the contribution of marketing to the strategy dialogue, market orientation has been singled out as being of particular importance in relation to the understanding of competitive advantage (Day et al 1992, Hunt and Lamb 2000). Research in the past has focused primarily on firms operating in domestic markets. As such, despite the recent progress, it is unclear of relevancy of market orientation as a construct in the context of multinational corporations (MNC) and their foreign subsidiaries. In this study, we set out to explore the role of market orientation in the subsidiary business performance. An investigation of a sample of 252 foreign subsidiaries in the UK revealed that except for “receptive? subsidiaries (Taggart 1998), market orientation has significant positive relationships with a number of business performance measures in all three other types of subsidiaries, suggesting that market orientation is a key driver for business performance at foreign subsidiaries.

The vibrational spectra of rectangular plates

The wire drive pulse-echo system has been extensively used to excite and measure modes of vibration of thin rectangular plates. The frequency spectra of different modes have been investigated as a function of the material elastic moduli and the plate geometry. Most of the work was carried out on isotropic materials. For square plates a wide selection of materials were used. These were made isotropic in their in-plane dimensions where the displacements are taking place. The range of rnaterials enabled the dependence on Poisson's ratio to be investigated. A method of determining the value of Poisson's ratio resulted from this investigation. Certain modes are controlled principally by the shear modulus. Of these the fundamental has two nodal lines across the plate surface. One of them, which has nodes at the corners, (the Lame mode) is uniquely a pure shear mode where the diagonal is a full wave length. One controlled by the Young's modulus has been found. The precise harmonic relationship of the Lame mode series in square and rectangular plates was established. Use of the Rayleigh-Lamb equation has extended the theoretical support. The low order modes were followed over a wide range of sides ratios. Two fundamental types of modes have been recognised; These are the longitudinal modes where the frequency is controlled by the length of the plate only and the 2~f product has an asymptotic value approaching the rod velocity. The other type is the in-plane flexural modes (in effect a flexurally vibrating bar where the -2/w is the geometrical parameter). Where possible the experimental work was related to theory. Other modes controlled by the width dimension of the plate were followed. Anisotropic materials having rolled sheet elastic symmetry were investigated in terms of the appropriate theory. The work has been extended to examine materials from welds in steel plates.

Glycogen, the preferred energy source for extracellular protein formation and growth of Aeromonas salmonicida

A study was made of the effect of supplementing a rich 3% (w/v) tryptone soya broth (TSB) medium and a poorer 1.7% (w/v) tryptone-based medium with glucose, maltose and glycogen, as carbon sources, on growth and exoprotein formation by Aeromonas salmonicida. In TSB, glucose inhibited growth and repressed exoprotein formation whilst maltose and glycogen had little effect, up to 20 h, when compared with an unsupplemented control. By contrast, in the poorer medium, over a 24-h incubation period, growth was stimulated three-fold by glycogen, and whilst exoprotein formation was low in comparison with that observed in TSB, the greatest production was observed in the presence of glycogen. Extracellular alpha-amylase was measured in the tryptone medium in the presence of the three carbon sources and the highest level, produced in the presence of glycogen, was 1.6 times that with added maltose whilst none was detectable with glucose present. This pattern was repeated in the case of the maltose-inducible porin, LamB, of the outer membrane.

Teaching and learning German language and culture in higher education in Britain:problems, challenges and didactical implications. A case study

The aim of this thesis is to explore key aspects and problems of the institutionalised teaching and learning of German language and culture in the context of German Studies in British Higher Education (HE). This investigation focuses on teaching and learning experiences in one department of German Studies in the UK, which is the micro-context of the present study, in order to provide an in-depth insight into real-life problems, strengths and weaknesses as they occur in the practice of teaching and learning German. Following Lamb (2004) and Holliday (1994), the present study acts on the assumption that each micro-context does not exist in vacuo but is always embedded in a wider socio-political and education environment, namely the macro-context, which largely determines how and what is taught. The macro-analysis of the present study surveys the socio-political developments that have recently affected the sector of modern languages and specifically the discipline of German Studies in the UK. It demonstrates the impact they have had on teaching and learning German at the undergraduate level in Britain. This context is interesting inasmuch as the situation in Britain is to a large extent a paradigmatic example of the developments in German Studies in English-speaking countries. Subsequently, the present study explores learning experiences of a group of thirty-five first year students. It focuses on their previous experiences in learning German, exposure to the target language, motivation, learning strategies and difficulties encountered, when learning German at the tertiary level. Then, on the basis of interviews with five lecturers of German, teaching experience in the context under study is explored, problems and successful teaching strategies discussed.

Vibration analysis of submerged rectangular microplates with distributed mass loading

This paper investigates the vibration characteristics of the coupling system of a microscale fluid-loaded rectangular isotropic plate attached to a uniformly distributed mass. Previous literature has, respectively, studied the changes in the plate vibration induced by an acoustic field or by the attached mass loading. This paper investigates the issue of involving these two types of loading simultaneously. Based on Lamb's assumption of the fluid-loaded structure and the Rayleigh–Ritz energy method, this paper presents an analytical solution for the natural frequencies and mode shapes of the coupling system. Numerical results for microplates with different types of boundary conditions have also been obtained and compared with experimental and numerical results from previous literature. The theoretical model and novel analytical solution are of particular interest in the design of microplate-based biosensing devices.

A prototype bone screw design for osteoporotic bone

Poster. Introduction: One in five menand one half of women over the age of 50 will experience a bone fracture, whichis frequently accompanied by poor bone health. This combination of poor bonehealth and fracture is a two edge sword, because not only does poor bone healthmake fractures more likely, it also reduces the efficacy of standard fracturetreatments. Currently available surgical fixation devices that were originallydeveloped for healthy bone, such as pins, plates and bone screws, are often noteffective for patients with osteoporosis, resulting in unsatisfactory outcomesor longer and more painful recovery times. One major issue is the design ofbone screws, which can loosen or pull-out from osteoporotic bone. Osteopenicscrews with larger outer thread diameters have been developed to try andaddress this problem. The larger diameter screws have been shown to be 60–70 %stronger in lab tests of individual screws but the larger diameter screwscannot be used with the standard spacing in fixation plates without the risk ofcausing fractures between the screws. In addition, many fractures occur nearjoints where there is not room to increase the spacing between screws.Therefore, new bone screws are needed for treatment of fractures in osteoporoticbone. Materials and Methods: Afterdeveloping a novel bone screw design, we fabricated screws using rapidprototyping methods. Screws were inserted into 10 pcf density sawbones polyurethanefoam as a model for osteoporotic bone. Pull-out tests were conducted using theprototype bone screw design and the standard screw design for comparison inaccordance with ASTM 543-13. Results and Discussion: Ourprototype screws have the same outer diameter as standard bone screws, but haveoptimised threads. For pull-out tests in 10 psf density sawbones poly-urethanefoam, the prototype screw design was 60 % stronger than the standard bone screwdesign (p<0.01). Conclusion: Our novel bonescrew design provides significant improvement in standard tests with syntheticbone material. Additional tests are needed to determine if the bone screwswould be suitable for human trials.

Inspection of parts with complex geometry and welds with structural health monitoring techniques

Structural Health Monitoring (SHM) systems were developed to evaluate the integrity of a system during operation, and to quickly identify the maintenance problems. They will be used in future aerospace vehicles to improve safety, reduce cost and minimize the maintenance time of a system. Many SHM systems were already developed to evaluate the integrity of plates and used in marine structures. Their implementation in manufacturing processes is still expected. The application of SHM methods for complex geometries and welds are two important challenges in this area of research. This research work started by studying the characteristics of piezoelectric actuators, and a small energy harvester was designed. The output voltages at different frequencies of vibration were acquired to determine the nonlinear characteristics of the piezoelectric stripe actuators. The frequency response was evaluated experimentally. AA battery size energy harvesting devices were developed by using these actuators. When the round and square cross section devices were excited at 50 Hz frequency, they generated 16 V and 25 V respectively. The Surface Response to Excitation (SuRE) and Lamb wave methods were used to estimate the condition of parts with complex geometries. Cutting tools and welded plates were considered. Both approaches used piezoelectric elements that were attached to the surfaces of considered parts. The variation of the magnitude of the frequency response was evaluated when the SuRE method was used. The sum of the square of the differences was calculated. The envelope of the received signal was used for the analysis of wave propagation. Bi-orthogonal wavelet (Binlet) analysis was also used for the evaluation of the data obtained during Lamb wave technique. Both the Lamb wave and SuRE approaches along with the three methods for data analysis worked effectively to detect increasing tool wear. Similarly, they detected defects on the plate, on the weld, and on a separate plate without any sensor as long as it was welded to the test plate.

Database of the GLAMAP project

A uniform chronology for foraminifera-based sea surface temperature records has been established in more than 120 sediment cores obtained from the equatorial and eastern Atlantic up to the Arctic Ocean. The chronostratigraphy of the last 30,000 years is mainly based on published d18O records and 14C ages from accelerator mass spectrometry, converted into calendar-year ages. The high-precision age control provides the database necessary for the uniform reconstruction of the climate interval of the Last Glacial Maximum within the GLAMAP-2000 project.

Avaliação da suplementação de vitamina E sobre a concentração de alfa-tocoferol no leite materno em mulheres com partos prematuros

The term vitamin E refers to a group of eight molecular compounds which differ in structure and bioavailability, and the RRR-alpha-tocopherol more biologically active form. The composition of vitamin E in breast milk undergoes variations during lactation, colostrum and milk richer in this micronutrient compared to transitional and mature milk. Newborns, especially premature infants are more susceptible to vitamin E deficiency and to prevent the damage caused by this deficiency has been proposed supplementation of neonates with this micronutrient, however, there is no consensus to carry out this intervention. Thus, maternal supplementation with RRRalpha-tocopherol in the postpartum period can be a good alternative to try to raise the alpha-tocopherol levels in breast milk and therefore provide the premature newborn adequate amounts of vitamin E. This study to evaluate the effect of supplementation with 400 UI acetate RRR-alpha-tocopherol in women with premature births, on the concentration of alpha-tocopherol in breast milk colostrum, transitional and mature. The study included 89 healthy adult women were enrolled in the control group (n = 51) and supplemented group (n = 38). Blood samples were collected and milk colostrum soon after birth (0h milk) twenty-four hours, new rate of colostrum milk was collected (24h milk). The transitional and mature milk were collected in seven days (7d milk) and thirty days (30d milk) after delivery, respectively. Supplementation in the supplemented group was held after the collection of blood and 0h milk. The alpha-tocopherol analyzes were performed by high-performance liquid chromatography. Serum levels of alpha-tocopherol less than 516 μg/dL were considered indicative of nutritional deficiency. The average concentration of alphatocopherol in the serum of the control group mothers was 1159.8 ± 292.4 μg/dL and the supplemented group was 1128.3 ± 407.2 μg/dL (p = 0.281). All women had nutritional status in vitamin E suitable. In both groups, it was observed that the concentration of vitamin E in colostrum milk was higher compared to transitional and mature milk. In the supplemented group, the concentration of alpha-tocopherol in the milk increased 60 % after supplementation, from 1339.3 ± 414.2 μg/dL (0h milk) to 2234.7 ± 997.3 μg/dL (24h milk). While the control group values in colostrum 0h and colostrum 24h were similar (p = 0.681). In the control group the follow-on milk alphatocopherol value was 875.3 ± 292.4 μg/dL and in the group supplemented 1352.8 ± 542.3 μg/dL, an increase of 35% in the supplemented group compared to control (p <0.001). In mature milk alpha-tocopherol concentrations between the control group (426.6 ± 187.5 μg/dL) and supplemented (416.4 ± 214.2 μg/dL) were similar (p = 0.853). Only 24h milk supplemented group answered the nutritional requirement of alpha-tocopherol (4 mg/day) of the newborn. These results show that the transport of this micronutrient for milk occurs in a controlled and limited way. Thus, the native vitamin E supplementation increases the concentration of alpha-tocopherol in colostrum and milk and transition does not influence the concentration in mature milk. Only the increase in colostrum milk was sufficient to meet the nutritional requirement of premature newborns.

Event layer chronology from Lake Suigetsu (Japan, SG06 Project) for the last 40 kyr

Event layers in lake sediments are indicators of past extreme events, mostly the results of floods or earthquakes. Detailed characterisation of the layers allows the discrimination of the sedimentation processes involved, such as surface runoff, landslides or subaqueous slope failures. These processes can then be interpreted in terms of their triggering mechanisms. Here we present a 40 kyr event layer chronology from Lake Suigetsu, Japan. The event layers were characterised using a multi-proxy approach, employing light microscopy and µXRF for microfacies analysis. The vast majority of event layers in Lake Suigetsu was produced by flood events (362 out of 369), allowing the construction of the first long-term, quantitative (with respect to recurrence) and well dated flood chronology from the region. The flood layer frequency shows a high variability over the last 40 kyr, and it appears that extreme precipitation events were decoupled from the average long-term precipitation. For instance, the flood layer frequency is highest in the Glacial at around 25 kyr BP, at which time Japan was experiencing a generally cold and dry climate. Other cold episodes, such as Heinrich Event 1 or the Late Glacial stadial, show a low flood layer frequency. Both observations together exclude a simple, straightforward relationship with average precipitation and temperature. We argue that, especially during Glacial times, changes in typhoon genesis/typhoon tracks are the most likely control on the flood layer frequency, rather than changes in the monsoon front or snow melts. Spectral analysis of the flood chronology revealed periodic variations on centennial and millennial time scales, with 220 yr, 450 yr and a 2000 yr cyclicity most pronounced. However, the flood layer frequency appears to have not only been influenced by climate changes, but also by changes in erosion rates due to, for instance, earthquakes.

Theoretical modeling and experimental validation of fluid-loaded micro rectangular plates

This paper presents a theoretical model on the vibration analysis of micro scale fluid-loaded rectangular isotropic plates, based on the Lamb's assumption of fluid-structure interaction and the Rayleigh-Ritz energy method. An analytical solution for this model is proposed, which can be applied to most cases of boundary conditions. The dynamical experimental data of a series of microfabricated silicon plates are obtained using a base-excitation dynamic testing facility. The natural frequencies and mode shapes in the experimental results are in good agreement with the theoretical simulations for the lower order modes. The presented theoretical and experimental investigations on the vibration characteristics of the micro scale plates are of particular interest in the design of microplate based biosensing devices.
