The Coloniality of Language: Race, Expressivity, Power, and the Darker Side of Modernity

This article presents a new framework to analyze linguistic relations of power that examines the linguistic effects of what Aníbal Quijano has theorized as “the coloniality of power.” The argument is organized in two sections. The first section introduces “the coloniality of language,” an expression the author uses to refer to the process of racialization of colonized populations as communicative agents beginning in the sixteenth century and continuing until today. This section includes an account of the language and communication paradigm being developed at the time of the Conquest, which, the author argues, contains the coloniality inside. In the second section, the author proposes to shift paradigms to get outside the “conceptual and social prison” of modernity/coloniality and understand colonized-colonialized languages and colonized- colonialized speakers differently. The conclusion illustrates some ideas and concerns about accessing and fostering decolonial alternatives that come forth from the article’s critical analysis

The focal attention window size explains letter substitution errors in reading

Acquired Neglect Dyslexia is often associated with right-hemisphere brain damage and is mainly characterized by omissions and substitutions in reading single words. Martelli et al. proposed in 2011 that these two types of error are due to different mechanisms. Omissions should depend on neglect plus an oculomotor deficit, whilst substitutions on the difficulty with which the letters are perceptually segregated from each other (i.e., crowding phenomenon). In this study, we hypothesized that a deficit of focal attention could determine a pathological crowding effect, leading to imprecise letter identification and consequently substitution errors. In Experiment 1, three brain-damaged patients, suffering from peripheral dyslexia, mainly characterized by substitutions, underwent an assessment of error distribution in reading pseudowords and a T detection task as a function of cue size and timing, in order to measure focal attention. Each patient, when compared to a control group, showed a deficit in adjusting the attentional focus. In Experiment 2, a group of 17 right-brain-damaged patients were asked to perform the focal attention task and to read single words and pseudowords as a function of inter-letter spacing. The results allowed us to confirm a more general association between substitution-type reading errors and the performance in the focal attention task

Cholesterol metabolism after bariatric surgery in grade 3 obesity : differences between malabsorptive and restrictive procedures

OBJECTIVEdMalabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the changes of cholesterol metabolism induced by malabsorptive and restrictive surgery independent of weight loss. RESEARCH DESIGNANDMETHODSdIn a nonrandomized, self-selected, unblinded, active-comparator, bicenter, 6-month study, glucose metabolism (blood glucose and serum insulin levels and homeostasis model assessment of insulin resistance [HOMA-IR] index) and cholesterol metabolism (absorption: serum campesterol and sitosterol levels; synthesis: serum lathosterol levels; catabolism: rate of appearance and serum concentrations of serum 7-a- and serum 27-OH-cholesterol after infusions of deuterated 7-a- and 27-OH-cholesterol in sequence) were assessed in grade 3 obesity subjects undergoing BIBP (n = 10) and AGB (n = 10). Evaluations were performed before and 6 months after surgery. RESULTSdSubjects had similar values at baseline.Weight loss was similar in the two groups of subjects, and blood glucose, insulin levels, HOMA-IR, and triglycerides decreased in a similar way. In contrast, serumcholesterol, LDL cholesterol, non-HDL cholesterol, serum sitosterol, and campesterol levels decreased and lathosterol levels increased only in BIBP subjects, not in AGB subjects. A significant increase in 7-a-OH-cholesterol occurred only with BIBP; serum 27-OHcholesterol decreased in both groups. CONCLUSIONSdMalabsorptive surgery specifically affects cholesterol levels, independent of weight loss and independent of glucose metabolism and insulin resistance. Decreased sterol absorption leads to decreased cholesterol and LDL cholesterol levels, accompanied by enhanced cholesterol synthesis and enhanced cholesterol catabolism. Compared with AGB, BIBP provides greater cholesterol lowering

Ontogenetic Profile of the Expression of Thyroid Hormone Receptors in Rat and Human Corpora Cavernosa of the Penis

Introduction. In the last few years, various studies have underlined a correlation between thyroid function and male sexual function, hypothesizing a direct action of thyroid hormones on the penis. Aim. To study the spatiotemporal distribution of mRNA for the thyroid hormone nuclear receptors (TR) alpha 1, alpha 2 and beta in the penis and smooth muscle cells (SMCs) of the corpora cavernosa of rats and humans during development. Methods. We used several molecular biology techniques to study the TR expression in whole tissues or primary cultures from human and rodent penile tissues of different ages. Main Outcome Measure. We measured our data by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) amplification, Northern blot and immunohistochemistry. Results. We found that TR alpha 1 and TR alpha 2 are both expressed in the penis and in SMCs during ontogenesis without development-dependent changes. However, in the rodent model, TR beta shows an increase from 3 to 6 days post natum (dpn) to 20 dpn, remaining high in adulthood. The same expression profile was observed in humans. While the expression of TR beta is strictly regulated by development, TR alpha 1 is the principal isoform present in corpora cavernosa, suggesting its importance in SMC function. These results have been confirmed by immunohistochemistry localization in SMCs and endothelial cells of the corpora cavernosa. Conclusions. The presence of TRs in the penis provides the biological basis for the direct action of thyroid hormones on this organ. Given this evidence, physicians would be advised to investigate sexual function in men with thyroid disorders.

Detection of rubella antibodies in human serum by the indirect fluorescent antibody technique

Antibodies for rubella virus were detected in human serum and titrated by the indirect method of immunofluorescence using a chronically infected, continuous line of monkey kidney cells as antigen. Positive reactions were obtained with convalescent or post-exposure specimens while acute sera and those from unexposed individuals were negative.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41678/1/705_2005_Article_BF01253854.pd
