Thermal analysis and synergistic tools for the development of a semi-permanent hair straightening technology
No full textThis research was carried out with the objective to develop a thermal analysis protocol into a method of damage assessment and claims support for a new semi-permanent hair straightening technology. The investigation determined the effects of the treatment on hair fibre composition and properties using Modulated Differential Scanning Calorimetry (MDSC) [1], Fourier Transform Infrared Spectroscopy (FTIR) [2], Gel Electrophoresis (SDS-PAGE) [3] and curl retention tests [4]. The effects of the new cysteamine treatment are compared with effects of a standard thioglycolate treatment and the daily use of straightening irons. Virgin, Caucasian hair was treated once with each chemical treatment and washed every day for 84 days. In a parallel study, hair was washed and straightened repeatedly using a standardised protocol at 190oC for 84 days. Samples were taken after 2, 28, 56 and 84 days for analysis by MDSC in water, ATR- and Trans-FTIR. Separate samples were treated once and subjected to curl retention tests and protein analysis. DSC measurements in water yield the keratin denaturation enthalpy (ΔHD), which relates to the thermal stability of the keratin intermediate filaments (KIFs), and the denaturation temperature (TD), which relates to the properties of the keratin associated-proteins (KAPs). The results show that chemical and thermal straightening cause a reduction in α-helix content and matrix viscosity. FTIR measurements give information on the formation of cysteic acid in the cuticle cells and the cortex. ATR-FTIR showed that the cysteamine–based treatment produces less cysteic acid in the cuticle layers than the standard treatment. Curl retention and SDS-PAGE were used to show the variability in the efficacy of the cysteamine treatment related to the heterogeneity of human hair. The results from both tests show that an individual’s hair will react with the product to a different extent, depending on the extractability of the keratin protein groups.In conclusion, we deduce that all straightening techniques, chemical and thermal, have a pronounced effect on the structural and chemical properties of hair fibres. These effects can be used to further develop and optimize this and related products. DSC has been shown to be an integral synergistic technique for the investigation of changes to hair morphology.This research was supported by the UK Technology Strategy Board under the Knowledge Transfer Partnership scheme.Cyril Keattch Award, Thermal Methods Group, Royal Society of Chemistry, 2014.[1] F.J.

Probleme und Potenziale gendermedizinischer Operationalisierung von Geschlecht
No full textWortmann L. Probleme und Potenziale gendermedizinischer Operationalisierung von Geschlecht. GENDER – Zeitschrift für Geschlecht, Kultur und Gesellschaft. 2023;15(1):104-118.Die Gendermedizin hat in den letzten Jahrzehnten zunehmend an Bedeutung gewonnen. Kritik an androzentrischen Wissenspraktiken, vergeschlechtlichte Objekt-Subjekt-Relationen und der Gender Data Gap bildeten den Keim gendermedizinischer Forschung. Die Geschlechterperzeption kann als eine Schlüsselfrage der Gendermedizin verstanden werden, welche die Operationalisierung von Geschlecht intradisziplinär verhandelt. Bislang scheitert sie dabei an einer homogenen Definition und hält an Paradigmen quantitativer Wissenspraktiken fest. Die Komplexität der Kategorie Geschlecht verlangt jedoch nach vielschichtigen Betrachtungen, die über disziplinäre Grenzen hinausgehen. Insgesamt bieten die in den Wissenspraktiken, der Geschlechterperzeption und dem inter-/transdisziplinären Verständnis verorteten Forschungsfelder um die Operationalisierung von Geschlecht Räume, in denen sich die Gendermedizin, Feminist Science Studies, Gender Studies und weitere treffen können und müssen
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
