Ser y parecer profesionales. La construcción de la imagen pública de mujeres futbolistas de dos clubes platenses (Argentina)
Authors: Arambuena Rita Lorena 
Published: June 2024

En el contexto de un exponencial crecimiento del fútbol como mercancía global, la consecución y exhibición de una “imagen profesional” se avizoran como una necesidad de la etapa de desarrollo que atraviesa el fútbol femenino en Argentina. Asimismo, como un imperativo para las futbolistas en relación al lugar subalterno y los prejuicios que circulan sobre su supuesta “falta de rentabilidad” en este deporte. En el artículo busco aproximarme a algunos sentidos que mis interlocutoras construyen sobre el profesionalismo, desde el punto de vista de la construcción de su propia imagen en el espacio público y en las redes sociales. Para ello, me baso en entrevistas en profundidad a un grupo de futbolistas de Primera División de dos clubes de la ciudad de La Plata (región metropolitana de Buenos Aires) y en observaciones de campo de mi investigación doctoral en curso sobre el proceso de profesionalización de la disciplina en el país. El propósito del artículo es visualizar algunas transformaciones que se están produciendo en este campo y problematizar ciertas implicancias que el ingreso al profesionalismo tiene sobre las subjetividades y modos de identificación de las mujeres futbolistas.

Authors: Mishra Shambhu Nath , Kumar Rahul , Panwar Vijender Pal 
Published: June 2024

Aims: This study is significant as it elucidates the relationship between floristic composition and soil nutrient availability of India's Saranda Sal (Shorea robusta Gaertn.) forest.
Study Design: Vegetation sampling was done following a grid of 5 km x 5 km, and soil sampling was done in each sampling plot using a Z-pattern.
Place and Duration of Study: The study was conducted in Saranda Forest of West Singhbhum district, Jharkhand, Eastern India, during 2021-2022
Methodology: Sampling has been designed as grid methods (5 km X 5 km) following a forest survey of India, and vegetation sampling was done by quadrat method. The soil samples were collected from three depths (i.e., surface: 0–30 cm, sub-surface: 30–60 cm and inner: 60-90 cm from each selected site. ANOVAs were used to compare the chemical properties of soil samples from various forests. Pearson correlation analyses to examine the effects of climatic variables on chemical properties of the soil of selected Sal forest as well as their relation with plant diversity.
Results: A comprehensive analysis of 5432 vascular plants from 65 species and 34 families was conducted across the 17 sites. Fabaceae is the most dominant family with 07 species. The study also examined soil chemical parameters and micronutrients in different sites and established their relations with vegetation dynamics. Notably, tree density showed a significant positive correlation with soil pH (r=0.59, p<0.05), but a significant negative correlation with Shannon diversity (H') (r=-0.53, p<0.05). Similarly, there was a significant positive correlation of Organic carbon with copper (r=0.59, p<0.05) and iron (r=0.61, p<0.00); however, there was a significant negative correlation with Available Phosphorus (r=-0.52, p<0.05).
Conclusion: Research findings underscore the importance of soil nutrients in promoting forest health and growth. Importantly, they can guide the formulation of practical and effective soil-forest management strategies for S. robusta and its associated forests, directly benefiting the forestry and environmental science community.

An experimental study was carried out to assess the toxicological aspects of methanolic extract of leaves and stems of Trema orientalis (METO) in rats. Repeated dose 28-day oral toxicity study of METO was performed in male Wistar albino rats as per the OECD guidelines 407. In total, 24 rats were assigned in four groups of six in each group. Group I served as control, while Group II, III and IV rats were orally gavaged with METO daily at dose levels of 250, 500 and 1000 mg/kg respectively for 28 days. The experimental rats were apparently healthy throughout the experimental period with respect to feed intake and body weight gain. Haematological parameters such as total erythrocytes count (TEC), total leukocyte count (TLC), haemoglobin (Hb) and packed cell volume (PCV) were assessed from blood on day 14 and day 28 in the repeated dose oral toxicity study. Also, certain biochemical parameters like AST, ALT, ALP, BUN and creatinine from serum were estimated. TLC was reduced significantly (p < 0.05) in group IV of METO treated rats. The significant (p < 0.05) increase in creatinine values of group IV on 28th day, associated with occurrence of various phytochemicals. Other haematological and biochemical parameters showed no significant changes in METO treated groups. The study concluded that the doses of T. orientalis resulted in pulmonary, hepatic and renal damage in experimental rats and might be toxic to the domestic animals also, which need to be investigated in future.

Efficient One‐step Synthesis and Properties of Photochromic Diarylethenes Having an Indene Bridging Unit
Authors: Jin Jiayu , Zou Lei 
Published: November 2011

AbstractTwo novel isomeric photochromic diarylethenes with an indene bridging unit have been prepared by a simple and efficient one‐step synthesis method. Their properties, including photochromic behavior, fluorescent properties and fatigue resistance, have been investigated. These two isomeric compounds showed photochromic back‐and‐forth reactions with ultraviolet and visible light both in solution and in PMMA film. Their ring‐open forms exhibited appreciable fluorescence, which was quenched by the ring‐closed forms. All results indicated that diarylethenes derivatives with indene‐aryl bridges exhibited rather high fatigue resistance and good thermally irreversible photochromic properties.

Published: November 2011

AbstractColorectal cancer (CRC) is the third commonest malignancy cancer worldwide. Clear understandings of global metabolic profiling of the normal mucosa and cancer tissues are vitally important to aid optimizing the clinical management strategy and understanding CRC biology. We studied metabolic characteristics of 20 CRC and 20 distant normal mucosa tissues extracts from 20 patients using high resolution 1H NMR spectroscopy in conjunction with multivariate analyses, such as principal component analysis (PCA). Compared with distant normal mucosa tissues, lactate, taurine, ornithine and polyamine were present at significantly higher levels in CRC tissue extracts whereas myo‐inositol was present at significantly lower level. Two metabolites ratios such as myo‐inositol/taurine and myo‐inositol/(ornithine+polyamine) appear to be the most valuable biomarkers for the differentiation CRC from normal mucosa tissues. Our data suggested that HR 1H NMR spectroscopy combined with multivariate analyses is a potentially useful technology for detecting malignant changes in the normal mucosa tissues, the technique may be further exploited for future CRC biomarker research or identification of targets for therapeutic manipulations.
Voltage endurance characteristics of epoxy/silica nanocomposites
Authors: Iizuka Tomonori , Uchida Katsumi , Tanaka Toshikatsu 
Published: November 2011

AbstractTwo kinds of epoxy/silica nanocomposites, specifically Aerosil and Nanopox specimens, were prepared to clarify the effect of nano‐filler dispersion and of coupling agents on electric field endurance. According to SEM observation, nano‐fillers were well dispersed in the former specimens, while some agglomeration was found in the latter specimens. This difference caused different characteristics for partial discharge resistance and treeing resistance. Partial discharge resistance was improved only by adding nano‐fillers, and treeing resistance was improved not only by adding nano‐fillers but also by uniformly dispersing the nano‐fillers. Coupling agents were also effective for treeing resistance in both kinds of specimens. It was then clarified that nano‐fillers and coupling agents could improve partial discharge and treeing resistance, but that treeing resistance could be upgraded or degraded depending on the level of nano‐filler dispersion. © 2011 Wiley Periodicals, Inc.

Psychiatric diagnosis in the elderly referred to a consultation‐liaison psychiatry service in a general geriatric hospital in Japan
Authors: Yamada Kenshi , Hosoda Masuhiro , Nakashima Sayaka , Furuta Kou , Awata Shuichi 
Published: November 2011

Aim:  Because depression is a common disorder in later life, elderly patients with delirium can be misdiagnosed as having depression. This study aimed to compare psychiatric diagnoses in the elderly made by referring doctors and psychiatrists.Method:  Consecutive non‐psychiatric inpatients aged 65 years or older that were referred to a consultation‐liaison (C‐L) psychiatry service of a general hospital in Japan were enrolled. An attending psychiatrist recorded the physical and psychiatric diagnoses of the referring doctors, reason for referral, psychotropic medication and sociodemographics. The psychiatrist recorded the psychiatric diagnosis after discussion with another psychiatrist in the C‐L psychiatry service. A researcher categorized the diagnoses of the referring physicians and psychiatrists as F0 (organic brain syndrome), F1 (mainly alcoholism), F2/3 (mainly depression) and F4/5 (neurosis/insomnia) using The International Classification of Mental and Behavioural Disorders, Tenth Revision (ICD‐10). The degree of agreement between doctors' and psychiatrists' diagnoses was estimated for each F category using kappa statistics.Results:  Of the 192 referred inpatients, 172 were enrolled (79 [45.9%] men; mean age 81.6 ± 7.8 years). Concordance of diagnosis between doctors and psychiatrists was achieved for F0, F1, F2/3 and F4/5, resulting in kappa statistics of 0.47, 0.27, 0.28 and 0.32, respectively. The psychiatrists in this survey diagnosed 12 cases of delirium and four cases of psychoactive substance‐use disorders in 23 cases of depression diagnosed by the referring doctors.Conclusion:  The referring doctors in this survey had an insufficient level of diagnostic accuracy for psychiatric disorders. Delirium and psychoactive substance‐use disorders were often misdiagnosed as depression. Geriatr Gerontol Int 2012; 12: 304–309.
Dementia on the Byzantine throne (ad 330–1453)

Published: November 2011

Aim:  To present the consequences of the prolonged age of the emperors, especially if combined with symptoms of dementia, during the Byzantine period (ad 330–1453).Methods:  A review of the original historical and literal sources referring to the life and political course of all the aged Byzantine emperors (a range of 87 total persons who ascended the throne).Results:  Seven Byzantine emperors out of 87 reached older age and showed symptoms that are attributed to dementia, as well as other manifestations of prolonged life. Most of the Byzantine medical authors attempted to connect dementia with certain multifactor agents and some of them interpreted the symptoms as being influenced by the brain's pathogenic humor or focused on the role of vascular diseases. However, an elderly leader afflicts his personal destiny, as well as the succession of the throne and the history of the whole nation. Sometimes, a delay in diagnosis and recognition of the loss of the somatic and mental ability of the emperor made scientific intervention useless and the patient's behavior was dangerous for the citizens of the state.Conclusion:  Even in contemporary societies, extended life expectancy results in leaders of older age, suffering from various diseases connected with gerontology. Loss of mental skills is considered dangerous and remains a problem from antiquity to the modern day. Byzantium handled all these cases with diplomacy. Geriatr Gerontol Int 2012; 12: 405–412.
Multi‐touch tables and collaborative learning
Authors: Higgins Steve , Mercier Emma , Burd Liz , Joyce‐Gibbons Andrew 
Published: November 2011

AbstractThe development of multi‐touch tables, an emerging technology for classroom learning, offers valuable opportunities to explore how its features can be designed to support effective collaboration in schools. In this study, small groups of 10‐ to 11‐year‐old children undertook a history task where they had to connect various pieces of information about a mining accident to reach a consensus about who had been responsible. Their interaction using traditional resources was compared with their interaction when using a multi‐touch table. Analysis suggests that the design and capabilities of the multi‐touch technology offers some key features that supported the collaboration and interaction of the participants, particularly in the early stages of the task. Some of these features appear to provide new opportunities for collaboration and interaction, which were different from the interactions observed in the paper‐based groups. These features of the multi‐touch surface therefore appear to support effective interaction between the pupils.Practitioner NotesWhat is already known about this topic
Research suggests that collaborative interaction supports learning.
Features such as the nature of the task and the social interaction influence these outcomes.
What this paper adds
This paper looks specifically at the possibilities when a large multi‐touch table is used to support collaboration.
It compares paper‐based and multi‐touch versions of the same activity involving school pupils.
Implications for practice and/or policy
Multi‐touch surfaces can support collaborative interaction.
The initial stages of the task were significantly different.
Pupils should be encouraged to reach a consensus about what they have to do and how they are going to do it as well as encouraged to produce a joint solution.
Productivity and Producer Welfare in the Presence of Production Risk
Authors: Orea Luis , Wall Alan 
Published: November 2011

AbstractProduction risk is an inherent characteristic of agriculture and changes in production risk will affect the welfare of risk‐averse producers. Using standard concepts from the literature on uncertainty, we introduce a welfare measure which comprises total factor productivity (TFP), production risk and farmer risk preferences, and which reflects the impact on producer welfare of changes in production technology. An empirical application is carried out using data from a sample of Spanish dairy farms which shows how the positive impact of increases in TFP on welfare can be offset by increases in the risk premium (‘cost of risk’) to the point where welfare may decrease.
The Polyketide Pks1 Contributes to Biofilm Formation in Mycobacterium tuberculosis
Authors: Pang Jennifer M. , Layre Emilie , Sweet Lindsay , Sherrid Ashley , Moody D. Branch , Ojha Anil , Sherman David R. 
Published: November 2011

ABSTRACT

Infections caused by biofilms are abundant and highly persistent, displaying phenotypic resistance to high concentrations of antimicrobials and modulating host immune systems. Tuberculosis (TB), caused by
Mycobacterium tuberculosis
, shares these qualities with biofilm infections. To identify genetic determinants of biofilm formation in
M. tuberculosis
, we performed a small-scale transposon screen using an
in vitro
pellicle biofilm assay. We identified five
M. tuberculosis
mutants that were reproducibly attenuated for biofilm production relative to that of the parent strain H37Rv. One of the most attenuated mutants is interrupted in
pks1
, a polyketide synthase gene. When fused with
pks15
, as in some
M. tuberculosis
isolates,
pks1
contributes to synthesis of the immunomodulatory phenolic glycolipids (PGLs). However, in strains such as H37Rv with split
pks15
and
pks1
loci, PGL is not produced and
pks1
has no previously defined role. We showed that
pks1
complementation restores biofilm production independently of the known role of
pks1
in PGL synthesis. We also assessed the relationship among biofilm formation, the
pks15/1
genotype, and
M. tuberculosis
phylogeography. A global survey of
M. tuberculosis
clinical isolates revealed surprising sequence variability in the
pks15/1
locus and substantial variation in biofilm phenotypes. Our studies identify novel
M. tuberculosis
genes that contribute to biofilm production, including
pks1
. In addition, we find that the ability to make pellicle biofilms is common among
M. tuberculosis
isolates from throughout the world, suggesting that this trait is relevant to TB propagation or persistence.
