Climatologically significant effects of space-time averaging in the North Atlantic sea - air heat flux fields

Differences between “classical” and “sampling” estimates of mean climatological heat fluxes and their seasonal and interannual variability are considered on the basis of individual marine observations from the Comprehensive Ocean–Atmosphere Data Set. Calculations of fluxes were done for intramonthly averaging and for 1°–5° spatial averaging. Sampling estimates give in general 10% to 60% higher values of fluxes than do classical estimates. Spatial averaging has a larger effect than temporal averaging in the Tropics and subtropics, and temporal averaging is more effective than spatial averaging in midlatitudes. The largest absolute differences between sampling and classical estimates of fluxes are observed in middle latitudes, where they are 15 to 20 W m−2 for sensible heat flux and 50 to 70 W m−2 for latent heat flux. Differences between sampling and classical estimates can change the annual cycle of sea–air fluxes. There is a secular tendency of increasing “sampling- to-classical” ratios of 1% to 5% decade−1 over the North Atlantic. Relationships between sampling-to-classical ratios and parameters of the sea–air interface, the number of observations, and the spatial arrangement of samples are considered. Climatologically significant differences between sampling and classical estimates are analyzed in terms of the contribution from different covariances between individual variables. The influence of different parameterizations of the transfer coefficients on sampling minus classical differences is considered. Parameterizations that indicate growing transfer coefficients with wind speed give the larger sampling minus classical differences in comparison with those based on either constant or decreasing with wind coefficients. Nevertheless, over the North Atlantic midlatitudes, all parameterizations indicate significant sampling minus classical differences of about several tens of watts per square meter. The importance of differences between sampling and classical estimates for the evaluation of meridional heat transport shows that differences between sampling and classical estimates can lead to 0.5–1-PW differences in meridional heat transport estimates

The International Headquarters–Subsidiary Relationship: Projecting Economic Cultural Influences on Management within Selected EU Countries

Through the recent European Union (EU) enlargement it is now supposed that there exists significant divergence within European economic cultures that can negatively impact international managerial functions. This article systematically investigates two dimensions through which economic culture can be measured and compared between four EU countries: Slovenia, a new Central European entrant into the EU, and Germany, Austria and Denmark, three westernized EU members, and projects their respective impacts onto several international management functions. The findings suggest that there exists a strong link between highly interpersonal and institutional trust driven economic cultures (IITDEC) to induce increased horizontal knowledge sharing. Further evidence was found, although statistically weaker, that IITDEC is negatively correlated to expatriate utilization. Results were also obtained regarding authority driven economic cultures (ADEC). A negative correlation between ADEC and decentralization was established as well as a negative correlation between ADEC and vertical knowledge flows.economic culture, headquarter–subsidiary relationship, international management

Report on the 19th SPACE Conference

The 19th international space (European Network for Business Studies and Languages) conference that recently took place in Spain provided valuable insight into several areas of interest. Most notably, methods on how to successfully enhance the internationalization of higher learning institutions were shared through mobility and joint degrees programs. Furthermore, the conference provided an academic forum for a highly professional and earnest discourse on pertinent topics of relevance for higher learning institutions, which this year pivoted around intercultural awareness and dialogue. In sum, the space network provides a wealth of academic and administrative advantages that the academic sphere could greatly benefit from.mobility, internationalization of higher learning institutions, intercultural awareness

Are National and Organizational Cultures Isomorphic? Evidence from a Four Country Comparative Study

This pilot study investigates whether organizational practices as observed through differing organizational cultures systematically replicate or reject national values. It is among the first to project delineated, narrow national cultural portrayals of Germany, Austria, Slovenia and Denmark against pattern-specific organizational cultures. Through country cluster analysis and correlation tests, the results achieve significance along all three dimensions. Trust allocations, authority perceptions and independence assertions were significant predictors for organizational traits of knowledge sharing practices, structure and control utilization, respectively. This demonstrates the value of assessing national values in conjunction with organizational culture in order to further understand the origins of corporate behaviour and the mechanisms that can help promote organizational effectiveness.national culture, organizational culture, multinational corporations, Europe

Variability of the winter wind waves and swell in the North Atlantic and North Pacific as revealed by the Voluntary Observing Ship data

This paper analyses secular changes and interannual variability in the wind wave, swell, and significant wave height (SWH) characteristics over the North Atlantic and North Pacific on the basis of wind wave climatology derived from the visual wave observations of voluntary observing ship (VOS) officers. These data are available from the International Comprehensive Ocean–Atmosphere Data Set (ICOADS) collection of surface meteorological observations for 1958–2002, but require much more complicated preprocessing than standard meteorological variables such as sea level pressure, temperature, and wind. Visual VOS data allow for separate analysis of changes in wind sea and swell, as well as in significant wave height, which has been derived from wind sea and swell estimates. In both North Atlantic and North Pacific midlatitudes winter significant wave height shows a secular increase from 10 to 40 cm decade−1 during the last 45 yr. However, in the North Atlantic the patterns of trend changes for wind sea and swell are quite different from each other, showing opposite signs of changes in the northeast Atlantic. Trend patterns of wind sea, swell, and SWH in the North Pacific are more consistent with each other. Qualitatively the same conclusions hold for the analysis of interannual variability whose leading modes demonstrate noticeable differences for wind sea and swell. Statistical analysis shows that variability in wind sea is closely associated with the local wind speed, while swell changes can be driven by the variations in the cyclone counts, implying the importance of forcing frequency for the resulting changes in significant wave height. This mechanism of differences in variability patterns of wind sea and swell is likely more realistic than the northeastward propagation of swells from the regions from which the wind sea signal originates

Role of the ocean in climate changes

The present program aimed at the study of ocean climate change is prepared by a group of scientists from State Oceanographic Institute, Academy of Science of Russia, Academy of Science of Ukraine and Moscow State University. It appears to be a natural evolution of ideas and achievements that have been developed under national and international ocean research projects such as SECTIONS, WOCE, TOGA, JGOFS and others. The two primary goals are set in the program ROCC. (1) Quantitative description of the global interoceanic 'conveyor' and it's role in formation of the large scale anomalies in the North Atlantic. The objectives on the way to this goal are: to get the reliable estimates of year-to-year variations of heat and water exchange between the Atlantic Ocean and the atmosphere; to establish and understand the physics of long period variations in meridianal heat and fresh water transport (MHT and MFWT) in the Atlantic Ocean; to analyze the general mechanisms, that form the MHT and MFWT in low latitudes (Ekman flux), middle latitudes (western boundary currents) and high latitudes (deep convection) of the North Atlantic; to establish and to give quantitative description of the realization of global changes in SST, surface salinity, sea level and sea ice data. (2) Development of the observational system pointed at tracing the climate changes in the North Atlantic. This goal merges the following objectives: to find the proper sites that form the inter annual variations of MHT; to study the deep circulation in the 'key' points; to develop the circulation models reflecting the principle features of interoceanic circulation; and to define global and local response of the atmosphere circulation to large scale processes in the Atlantic Ocean

Knowledge Resources and Competitive Advantage

The paper discusses some definitions of knowledge as a potential source of competitive advantage. It reviews the literature pertaining to the assessment of knowledge assets. According to the resource-based view, which links the competitive advantage of organizations with resources and capabilities that are firm-specific, and difficult to imitate or substitute, a firm’s competitive advantage is built on a set of strategically relevant resources (Barney 1991; Grant 1991; Peteraf 1993). When firms have access to similar resources, it is those companies that are able to maximize the utilization of those resources that attain a competitive advantage. Among various strategic resources and capabilities that help determine the extent of competitive advantages, a pivotal role is often assigned to knowledge – as both a resource in itself and an integrating factor that makes other resources and capabilities effective – especially in complex and dynamic environments.knowledge, competitiveness, firm performance, knowledge-based theory
