Opis:
The paper offers a secondary analysis from a grounded theory doctoral study that reconsiders its “grounded systemic design” (Mitchell, 2005, 2007). While theorists across multiple disciplines fiercely debate the ontological implications of Niklas Luhmann’s autopoietic systems theory (Deflem 1998; Graber and Teubner 1998; King and Thornhill 2003; Mingers 2002; Neves 2001; O’Byrne 2003; Verschraegen 2002, for example), few investigators have yet to adopt his core constructs empirically (see Gregory, Gibson and Robinson 2005 for an exception). Glaser’s (1992, 2005) repeated concerns for grounded theorists to elucidate a “theoretical code” has provided an additional entry point into this project of integrating grounded theory with Luhmann’s abstract conceptual thinking about how global society operates. The author argues that this integration of methodology and systems thinking provides an evolution of grounded theory – rather than its ongoing “erosion” as Greckhamer and Koro-Ljungberg (2005) have feared – and a transportable set of methodological and analytical constructs is presented as a basis for further grounded study.

Opis:
We present the hole-related electrical activity of the InAs quantum dots embedded in the n-type GaAs. We performed our experiments with the use of the Laplace and conventional deep level transient spectroscopies combined with the above GaAs band-gap illumination. We observed that depending on temperature and electric field the hole emission process is an interplay between the pure thermal emission and tunnelling processes. The tunnelling was quantitatively described by a simple model of the potential barrier.

Opis:
The space-time dynamics of chlorophyll a concentration and seawater excess viscosity has been investigated in the hydrographically contrasting inshore and offshore water masses of the eastern English Channel. This was done during the phytoplankton spring bloom dominated by Phaeocystis globosa before and after the very large-scale formation of foam induced by an increase in wind-driven turbulence and the related wave breakings. The results suggest that the dynamics of chlorophyll a concentration and seawater excess viscosity are differentially controlled by the formation of foam through the intensity of the spring bloom and wind-generated turbulence.

Opis:
In order to demonstrate that silicate (SiO3-Si) can be used as an indicator to study upwelling in the northern South China Sea, hierarchical cluster analysis (CA) and principle component analysis (PCA) were applied to analyse the metrics of the data consisting of 14 physical-chemical-biological parameters at 32 stations. CA categorized the 32 stations into two groups (low and high nutrient groups). PCA was applied to identify five Principal Components (PCs) explaining 78.65% of the total variance of the original data. PCA found important factors that can describe nutrient sources in estuarine, upwelling, and non-upwelling areas. PC4, representing the upwelling source, is strongly correlated to SiO3-Si. The spatial distribution of silicate from the surface to 200 m depth clearly showed the upwelling regions, which is also supported by satellite observations of sea surface temperature.
