G.H. Mead

G.H. Mead (1863-1931) oriented much of his intellectual efforts around three unavoidable questions for anyone living in a modern society: how are selfhood, knowledge, and politics understood and organized in such a society? Modern individuals continually seek answers to questions although nobody has ever come up with a definitive answer to them. Modernity, in other words, confronts us with inevitable problematics that fundamentally shape the way in which we think about certain topics. For the purposes of my discussion of Mead, I focus upon three of these modern problematics: science, selfhood, and democratic politics. But before I discuss Mead’s treatment of these problem areas, allow me to briefly situate Mead as a pragmatist in relation to Dewey and James within pragmatism.

Sex-specific disruption of murine midbrain astrocytic and dopaminergic developmental trajectories following antenatal GC treatment

The mammalian midbrain dopaminergic systems arising in the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) are critical for coping behaviours and are implicated in neuropsychiatric disorders where early life challenges comprise significant risk factors. Here, we aimed to advance our hypothesis that glucocorticoids (GCs), recognised key players in neurobiological programming, target development within these systems, with a novel focus on the astrocytic population. Mice received antenatal GC treatment (AGT) by including the synthetic GC, dexamethasone, in the mothers' drinking water on gestational days 16-19; controls received normal drinking water. Analyses of regional shapes and volumes of the adult SNc and VTA demonstrated that AGT induced long-term, dose-dependent, structural changes that were accompanied by profound effects on astrocytes (doubling/tripling of numbers and/or density). Additionally, AGT induced long-term changes in the population size and distribution of SNc/VTA dopaminergic neurons, confirming and extending our previous observations made in rats. Furthermore, glial/neuronal structural remodelling was sexually dimorphic and depended on the AGT dose and sub-region of the SNc/VTA. Investigations within the neonatal brain revealed that these long-term organisational effects of AGT depend, at least in part, on targeting perinatal processes that determine astrocyte density and programmed cell death in dopaminergic neurons. Collectively, our characterisation of enduring, AGT-induced, sex-specific cytoarchitectural disturbances suggests novel mechanistic links for the strong association between early environmental challenge (inappropriate exposure to excess GCs) and vulnerability to developing aberrant behaviours in later life, with translational implications for dopamine-associated disorders (such as schizophrenia, ADHD, autism, depression), which typically show a sex bias

Analysis of UV spectral bands using multidimensional scaling

This study describes the change of the ultraviolet spectral bands starting from 0.1 to 5.0 nm slit width in the spectral range of 200–400 nm. The analysis of the spectral bands is carried out by using the multidimensional scaling (MDS) approach to reach the latent spectral background. This approach indicates that 0.1 nm slit width gives higher-order noise together with better spectral details. Thus, 5.0 nm slit width possesses the higher peak amplitude and lower-order noise together with poor spectral details. In the above-mentioned conditions, the main problem is to find the relationship between the spectral band properties and the slit width. For this aim, the MDS tool is to used recognize the hidden information of the ultraviolet spectra of sildenafil citrate by using a ShimadzuUV–VIS 2550, which is in theworld the best double monochromator instrument. In this study, the proposed mathematical approach gives the rich findings for the efficient use of the spectrophotometer in the qualitative and quantitative studies.

Application of continuous wavelet transform to the analysis of the modulus of the fractional Fourier transform bands for resolving two component mixture

In this paper, the fractional Fourier transform (FrFT) is applied to the spectral bands of two component mixture containing oxfendazole and oxyclozanide to provide the multicomponent quantitative prediction of the related substances. With this aim in mind, the modulus of FrFT spectral bands are processed by the continuous Mexican Hat family of wavelets, being denoted by MEXH-CWT-MOFrFT. Four modulus sets are obtained for the parameter a of the FrFT going from 0.6 up to 0.9 in order to compare their effects upon the spectral and quantitative resolutions. Four linear regression plots for each substance were obtained by measuring the MEXH-CWT-MOFrFT amplitudes in the application of the MEXH family to the modulus of the FrFT. This new combined powerful tool is validated by analyzing the artificial samples of the related drugs, and it is applied to the quality control of the commercial veterinary samples.

Analysis of financial indices by means of the windowed Fourier transform

The goal of this study is to analyze the dynamical properties of financial data series from nineteen worldwide stock market indices (SMI) during the period 1995–2009. SMI reveal a complex behavior that can be explored since it is available a considerable volume of data. In this paper is applied the window Fourier transform and methods of fractional calculus. The results reveal classification patterns typical of fractional order systems.

Introducing the fractional-order Darwinian PSO

One of the most well-known bio-inspired algorithms used in optimization problems is the particle swarm optimization (PSO), which basically consists on a machinelearning technique loosely inspired by birds flocking in search of food. More specifically, it consists of a number of particles that collectively move on the search space in search of the global optimum. The Darwinian particle swarm optimization (DPSO) is an evolutionary algorithm that extends the PSO using natural selection, or survival of the fittest, to enhance the ability to escape from local optima. This paper firstly presents a survey on PSO algorithms mainly focusing on the DPSO. Afterward, a method for controlling the convergence rate of the DPSO using fractional calculus (FC) concepts is proposed. The fractional-order optimization algorithm, denoted as FO-DPSO, is tested using several well-known functions, and the relationship between the fractional-order velocity and the convergence of the algorithm is observed. Moreover, experimental results show that the FO-DPSO significantly outperforms the previously presented FO-PSO.

Seroprevalence of hepatitis e virus in domestic pigs and wild boars in Switzerland.

Hepatitis E is considered an emerging human viral disease in industrialized countries. Studies from Switzerland report a human seroprevalence of hepatitis E virus (HEV) of 2.6-21%, a range lower than in adjacent European countries. The aim of this study was to determine whether HEV seroprevalence in domestic pigs and wild boars is also lower in Switzerland and whether it is increasing and thus indicating that this zoonotic viral infection is emerging. Serum samples collected from 2,001 pigs in 2006 and 2011 and from 303 wild boars from 2008 to 2012 were analysed by ELISA for the presence of HEV-specific antibodies. Overall HEV seroprevalence was 58.1% in domestic pigs and 12.5% in wild boars. Prevalence in domestic pigs was significantly higher in 2006 than in 2011. In conclusion, HEV seroprevalence in domestic pigs and wild boars in Switzerland is comparable with the seroprevalence in other countries and not increasing. Therefore, prevalence of HEV in humans must be related to other factors than prevalence in pigs or wild boars.

Causas posibles de la drástica disminución de la longitud media de la merluza peruana en 1992

La drástica disminución de la longitud media de la merluza en 1992 fue hasta cierto punto inesperada para los biólogos pesqueros peruanos, acostumbrados a manejar esta población como un stock unitario controlando el rendimiento y la longitud mínima en las capturas. Durante toda la década de los años ochenta, el esfuerzo pesquero no fue muy alto y afectó principalmente a los grupos de edades IV+. Menos del 10% de los desembarques fueron de tallas menores a la longitud media de desove (35 cm). Por esto, la gran ocurrencia de tallas pequeñas de merluza a partir de marzo de 1992 en las capturas de todas las flotas dedicadas a esta especie, parecía deberse a las condiciones oceanográficas, ya que un evento El Niño Oscilación Sur (ENOS) se estaba desarrollando. Sin embargo, igual que en anteriores ENOS, se hubiera esperado un cambio de sitio de toda la población hacia el sur y lejos de la costa. Esto significaría que las merluzas jóvenes de tamaño mediano estarían mas al sur fuera del alcance de la flota de Paita. Contrario a lo esperado, durante El Niño 1991-93, debido a una intrusión de aguas oceánicas subtropicales, las merluzas grandes migraron hacia el norte. Mientras que El Niño podría haber actuado como un disparador, la causa fundamental de los cambios estructurales en la población fue la desaparición de la sardina como especie de presa principal para las merluzas grandes a partir de 1987, y la falta de pequeños Sciaenidae (bereche) durante El Niño, para las merluzas de tamaño medio. Lo primero podría deberse al alto esfuerzo pesquero sobre la sardina, en conjunto, probablemente, con una presión depredadora alta de una población sana de merluza a partir de mediados de la década de los años 80. Estudios futuros deben incluir las relaciones entre predador y presa en el ecosistema. Estas relaciones, que se desarrollaron durante largos períodos, probablemente soportan la estabilidad del sistema, y las pesquerías, que actúan como un fuerte depredador, deben ser incluidas en un modelo multiespecífico.
