Research methods in business: Quantitative and qualitative comparative analysis
2020
[EN] Research in the social sciences is built on either quantitative or qualitative analysis, depending on the research context. Using both quantitative and qualitative analyses in the same study presents major obstacles. In the real business world, empirical studies could benefit from using multiple research methodologies. Thus, this editorial presents an overview of the literature on quantitative and qualitative research methods in business research to clarify some key issues on the subject. The following section introduces the papers included in the special issue on "Research Methods in Business: Quantitative and Qualitative Comparative Analysis" and highlights several novel ideas, emerg…
Development of Customer-Orientation, Brand-Orientation and Business Performance within the First Ten Years of the Firm
2017
The business performance of young firms is significantly influenced by customer- and brand-oriented capabilities. These capabilities can be sustained competitive advantages for firms from an early age on and managers need to consciously develop them over time. In the first years, the development of these firms is still highly dependent on their environment. The products and services are still under development, and there are only little resources and market information available. Therefore, the development of customer-orientation, brand-orientation and their impact on business performance at this age is crucial to be understood for founders to appropriately manage these capabilities. The pu…

Correction of Matrix Effect in Multielemental Quantitative Analysis by X-Ray Fluorescence Spectroscopy Using the Linear Behavior in the Analytical Ra…
2002
This paper is an analytical study of the possibility of applying the linear range of the substitution-dilution method to correct the matrix effect in quantitative analysis by X-ray fluorescence (XRF) spectroscopy. The analytical range is obtained from a series of samples prepared in the form of glass discs by substituting the unknown sample with a standard sample (substitution factor, h) including a diluent-melt. In general, the substitution-dilution method is hyperbolic in character and therefore the diluent is required to ensure linear behavior between If vs. h in the experimental range. The linear range is located between the concentrations of standard and unknown for each element analy…
Quantitative analysis of localized surface plasmons based on molecular probing
2010
International audience; We report on the quantitative characterization of the plasmonic optical near-field of a single silver nanoparticle. Our approach relies on nanoscale molecular molding of the confined electromagnetic field by photoactivated molecules. We were able to directly image the dipolar profile of the near-field distribution with a resolution better than 10 nm and to quantify the near-field depth and its enhancement factor. A single nanoparticle spectral signature was also assessed. This quantitative characterization constitutes a prerequisite for developing nanophotonic applications.
Quantification of low levels of amorphous content in maltitol
2004
A method for the quantification of low levels of amorphous content of maltitol with hyper-DSC (high speed DSC) was developed. The method is based on the fact that the change of specific heat ( � Cp) at the glass transition is linearly proportional to the amorphous content. Twelve synthetic mixtures with various degrees of crystalline and amorphous maltitol were prepared. � Cp was determined at both fictive and
QUANTITATIVE ANALYSIS OF SPATIAL INDICATORS IN THE CASE OF VARYING ADMINISTRATIVE BOUNDARIES
2021
The aim of the research is to develop methods that would allow comparingthe statistical parameters of Latviaat differing administrative divisions, thereby solvingthe problems that arise in the case of discrepancy of borders. As part of thework, the developed method was implemented in order to assess the suitabilityof the created tool for mathematical analysis of statistical parameters on Latvia. Theterritory examined in the work is Latvia; the discrepancy of borderswas examined by comparing the parish borders of 1935 with the parishes of 2000.Therefore it was necessary to create a transfer matrix in order to link theadministrative borders of both periods. The transfer matrix was prepared in…
Stability of Morphine, Morphine-3-Glucuronide, and Morphine-6-Glucuronide in Fresh Blood and Plasma and Postmortem Blood Samples
2001
The present study was designed to determine the stability of morphine and its glucuronides in spiked fresh blood and plasma from live individuals as well as in four authentic postmortem blood specimens for a time interval of up to six months. The samples were stored in glass vials at -20 degrees C, 4 degrees C, and 20 degrees C. Additionally, spiked samples were exposed to light through window glass and subjected to a forced-degradation study at 40 degrees C. Data were established using solid-phase extraction and high-performance liquid chromatography coupled to atmospheric pressure ionization mass spectrometry for isolation and quantitation, providing a sensitive and specific detection met…
Concentration of Potentially Toxic Elements in Various Berries Grown in Allotment Gardens of Rīga City, Latvia
2017
Abstract Concentration of trace and major elements is an important indicator of nutritional value of food, also regarding cultivated food crops like fruits, berries, and vegetables. Concentration of elements differs regionally and is influenced by various factors. Nevertheless, some chemical elements (As, Cd, Hg, Ni, Pb, Zn, etc.) are known as environmental pollutants and may affect the quality and safety of crops and food products. The aim of the study was to determine the concentration of potentially toxic elements like Cd, Cr, Cu, Fe, Ni, Pb, and Zn in samples of berries grown in allotment gardens of Rīga city. Dried and homogenised samples of raspberries, strawberries, red currants, bla…
