Electrochemistry nanometric patterning of MOF particles: Anisotropic metal electrodeposition in Cu/MOF
2006
Abstract Electrodeposition of copper from Cu/MOF immersed into acetate buffer produces a quasi-periodic series of 10–20 nm sized laminae sandwiched within the pristine MOF lattice as monitored by voltammetry of microparticles/atomic force microscopy. This anisotropic patterning can be qualitatively described in terms of a highly orientation-dependent diffusion of electrons and charge-balancing electrolyte counterions in the MOF network.
Minimization of childhood maltreatment is common and consequential: results from a large, multinational sample using the childhood trauma questionnai…
2016
Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent struc…
A Metaphor for Identities in Transition through Urbanization and Globalization: Tofu and One Hundred Surnames
2019
The Chinese artist Chen Qiulin has been taking displacement and the resulting unrest in people’s identity as her persistent theme since the early 1990s. Focusing on a series of her works made since 2004 dealing explicitly with tofu and Chinese surnames, this paper examines her exploration of identities in transition in the context of China’s mass urbanization and globalization. By showing the artist’s conceptual evolution, her preference for materials and mediums, and her exhibition strategy, this paper explores two issues. First, it illuminates how the artist has transformed “tofu” and “surname” into a metaphor for the dilemma of identity under the urbanization in China. Second, it discuss…
Improved sample preparation for the testosterone hydroxylation assay using disposable extraction columns
1992
The preparation of samples for injection into a high-performance liquid chromatograph from assay mixtures for the determination of cytochrome P-450-dependent testosterone hydroxylation has been substantially facilitated. By replacing the multiple cumbersome extraction steps of the conventional method with a single column extraction the time for sample preparation was reduced from hours to minutes. The new procedure also yields better recoveries for most of the testosterone metabolites than the original protocol. The use of extraction columns for sample preparation allows the simultaneous treatment of a large number of samples or even the automation of the whole assay procedure. The modified…
Diurnal changes in the perception of emotions in music: Does the time of day matter?
2014
According to the Hindustani music tradition, the ability of a song to induce certain emotions depends on the time of day: playing a song at the right time is said to maximise its emotional effect. The present exploratory study investigated this claim by combining findings in chronobiology, mood research and music perception. It has already been established that some aspects of our mood fluctuations follow a cyclical pattern. Besides, it is a known fact that our current mood influences our perception and assessment of emotions. However, these elements have never been linked together in a study examining the effect of mood cyclicity on perceived emotions in music. To test the hypothesis of a…
Estudio sobre la cicatrización de la zona donante de injerto de piel parcial en pacientes quemados tras aplicación de plasma rico en plaquetas o plas…
2019
La técnica más empleada para la restauración de la barrera cutánea en los pacientes quemados es el injerto de piel autólogo de espesor parcial. Su obtención conlleva generar un área cruenta a nivel de otra localización cutánea del mismo paciente, conocida como zona donante. Esta área cura generalmente en un período de entre 7 y 14 días mediante un proceso de cicatrización dirigida. Cuando existen grandes defectos que requieren cobertura, como es el caso de los grandes quemados en los que la extensión de la quemadura limita la disponibilidad de área donante, pueden ser necesarias varias tomas de la misma zona. Por lo tanto, la opción terapéutica global en este tipo de pacientes va a depender…
Beyond BMI : waist circumference and social environment is associated with motor performance ability in kindergartners
2020
Abstract Background The aim of the current study was to examine the relationship between anthropometric characteristics (i.e. body height, body weight, body mass index [BMI] and waist circumference [WC]) with motor performance ability [MPA], social environmental factors of the district (i.e. employment status/working life, education, social situation/heterogeneity and home environment), where the respective kindergarten was located, as well as other potential health determinants in a representative sample of kindergartners. Methods We analyzed data of 434 children aged 3 to 6 years which were obtained from a community-based cross-sectional health study conducted in the city of Mainz, German…
A Proposal for an Automatic Stabilizer in Social Justice
2019
Abstract Generally, social justice has two sides which are intercorrelated and inter-dependend: a) constitutive social justice (for example, the so called commutative social justice); b) regulative social justice (for example, the so called distributive social justice). The paper approaches the regulative social justice, more exactly, an automatic mechanism to get it. To this end, an automatic stabilizer to provide distributive social justice, according to the Rawlsian principle of difference. Such an automatic stabilizer is grounded on the wealth, more precise, on the share of the wealth which is not invested in order to benefit to the more disadvantaged class of the society. Paper does no…
Extended music education enhances the quality of school life
2013
The claim of whether music education can create social benefits in the school environment was tested in 10 Finnish schools with an extended music curricular class and control classes. The quality of school life (QSL) was assessed by a representative sample (N=735) of pupils at years 3 and 6 (9- and 12-years-olds). The results showed that extended music education enhances the QSL, particularly in areas related to general satisfaction about the school and a sense of achievement and opportunity for students. Differences related to the schools and gender did not account for the results. A follow-up study examined whether the increase in critical QSL variables was related to music. This analysis…
Reframing Climate Justice : A Three-dimensional View on Just Climate Negotiations
2016
This article proposes reframing the justice discourse in climate negotiations. In so doing, it makes two claims. First, global climate negotiations deserve to be addressed as an issue of justice on their own due to their peculiar characteristics. Second, a multidimensional theory of justice is superior to distributional theories for this task. To support these arguments, I apply the multidimensional theory of justice to global climate negotiations. This analysis reveals that injustice in the negotiations is multidimensional and irreducible to distributional questions. Furthermore, it shows how promoting justice in this broad sense would have significant effect on the negotiation procedures …
