Ethylene glycol poisoning

A 40-year-old man was admitted to the emergency department after a suicide attempt. The patient was found at home unconscious, with an open bottle of antifreeze near him. The patient was in a coma on admission, but neurological examination excluded intracranial changes. Results of initial urine and serum toxicological screening tests were negative. Laboratory values indicated metabolic acidosis, leukocytosis, urinalysis revealed hematuria and unrecognized crystals. Osmolality and osmol gap were not determined on patient admission. Treatment with ethanol as an antidote and hemodialysis were started because of metabolic acidosis, anamnestic data and clinical status of the patient, and subsequently led to improvement of his condition. Further toxicological analyses of glycolic and oxalic acids in serum and urine samples were performed by ion-chromatography (IC) method and showed high values in spot urine and serum ultrafiltrate at admission, but during therapy the values progressively decreased. Treatment of poisoned patient for 3 weeks resulted in complete recovery.     

Chemical, physical and mineralogical characterization of soils from the Curitiba Metropolitan Region for forensic purpose

The objective of this paper is to propose a soil characterization methodology for forensic use, based on physical (textural and spectroscopic analyses), chemical (extractions with hydrofluoric acid, ammonium oxalate, sodium dithionite-citrate-bicarbonate and NaOH solution) and mineralogical (thermal analyses and X-ray diffraction) analyses. The study was carried out in the State of Paraná, Brazil, in three neighborhoods of Curitiba city and in two cities within the Curitiba Metropolitan Region. In order to verify the similarity between samples, four composite samples (repetitions) were prepared in each of the five studied sites. It was obtained a great number of quantitative variables (56) from a reduced amount of soil sample (1g). The variables selected from the chemical extractions (16) were more precise in grouping similar samples (same horizon and sampling site) as well as in separating samples collected in different horizons or sites. Seven distinct groups were formed, each with high intragroup similarity, but the unexpected dispersion of two samples (from a total of 40 samples) reduced the distinction of three other studied groups. The placement of the two samples in a different group and the higher dispersion (24 samples) for samples collected in the city of Curitiba are due to the great pedological homogeneity of this area (physical-chemical horizon characteristics, soil color and parent material). The methodology used in this work (analytical method and data treatment) presents high potential for forensic studies and can be easily validated for other areas.     

Britain’s Choice: Polarisation or Cohesion

Britain’s Choice, a report published by More in Common, develops a new segmentation of the British public based on their core beliefs, values and identities. Identifying seven segments, the report aims to better understand the British public, the goal being to work out how to build a more cohesive Britain—the choice facing Britain being a path to further division and polarisation or one to greater solidarity and shared values. The report strikes a broadly optimistic turn and highlights the shared values across the seven groups, but there are warning signs in the data that there are still many issues on which these groups could be divided, the overlap between them, for now, limiting the success of attempts to do so and throwing up a ‘kaleidoscopic’ pattern that changes from issue to issue.     

G. A. Cohen’s historical materialism: a feminist critique

ABSTRACT

Forty years on, G. A. Cohen’s reconstruction and defence of Marx’s theory of history is still widely, and justifiably, considered the best of its kind, and it remains unsurpassed in clarity, argumentation and textual support. This article presents an under-explored critique of the theory that arises once we recognize that it is meant to apply to the circumstances of women as well as men. The article argues that, when extended to women, the reconstructed theory’s predictions fail to materialize, its characterizations of historical stages fall apart, and its functional explanations appear implausible. In addition, although the theory claims to be able to explain the emergence and diffusion of different ideologies by their effects on productive development, it cannot plausibly explain the presence of sexist ideologies despite their pervasive and profound impact across history. The article concludes by showing that these flaws highlight the many respects in which Cohen’s orthodox version of Marxism is a conservative ideology, and one that egalitarians in particular should view with suspicion. Once we analyse the different components of the theory, the idea of a right-wing Marxism no longer seems as odd as it sounds.

Grant N. Havers,Leo Strauss and Anglo-American Democracy: A Conservative Critique

Grant Havers's Leo Straus and Anglo-American Democracy: A Conservative Critique seriously misrepresents Strauss's thought, largely as a result of Havers's determination to use the history of political philosophy for partisan purposes of his own, unlike Strauss's determined and meticulous effort to learn fromthe greatest philosophic writers both ancient and modern.?
