Corporate social responsibilities of Indian public sector enterprises-a case study of Bharat Heavy Electricals Limited (BHEL)

The high level of public accountability attached to Public Sector Enterprises as a result of public ownership makes them socially responsible. The Committee of Public Undertakings in 1992 examined the issue relating to social obligations of Central Public Sector Enterprises and observed that ``being part of the `State', every Public Sector enterprise has a moral responsibility to play an active role in discharging the social obligations endowed on a welfare state, subject to the financial health of the enterprise''. It issued the Corporate Social Responsibility Guidelines in 2010 where all Central Public Enterprises, through a Board Resolution, are mandated to create a CSR budget as a specified percentage of net profit of the previous year. This paper examines the CSR activities of the biggest engineering public sector organization in India, Bharath Heavy Electricals Limited. The objectives are twofold, one, to develop a case study of the organization about the funds allocated and utilized for various CSR activities, and two, to examine its status with regard to other organizations, the 2010 guidelines, and the local socio-economic development. Secondary data analysis results show three interesting trends. One, it reveals increasing organizational social orientation with the formal guidelines in place. Two, Firms can no longer continue to exploit environmental resources and escape from their responsibilities by acting separate entities regardless of the interest of the society and Three the thrust of CSR in public sector is on inclusive growth, sustainable development and capacity building with due attention to the socio-economic needs of the neglected and marginalized sections of the society.

Alcohol attention bias in adolescent social drinkers: an eye tracking study

Rationale
Previous research on attention bias in nondependent social drinkers has focused on adult samples with limited focus on the presence of attention bias for alcohol cues in adolescent social drinkers.
Objectives
The aim of this study was to examine the presence of alcohol attention bias in adolescents and the relationship of this cognitive bias to alcohol use and alcohol-related expectancies.
Methods
Attention bias in adolescent social drinkers and abstainers was measured using an eye tracker during exposure to alcohol and neutral cues. Questionnaires measured alcohol use and explicit alcohol expectancies.
Results
Adolescent social drinkers spent significantly more time fixating to alcohol stimuli compared to controls. Total fixation time to alcohol stimuli varied in accordance with level of alcohol consumption and was significantly associated with more positive alcohol expectancies. No evidence for automatic orienting to alcohol stimuli was found in adolescent social drinkers.
Conclusion
Attention bias in adolescent social drinkers appears to be underpinned by controlled attention suggesting that whilst participants in this study displayed alcohol attention bias comparable to that reported in adult studies, the bias has not developed to the point of automaticity. Initial fixations appeared to be driven by alternative attentional processes which are discussed further.

Bright’s Wines Limited fonds, 1983-1989

One of the oldest wineries in Ontario, Bright’s Wines is now a part of Vincor International Inc. and still producing wines today. In the year 1874 Thomas G. Bright and Francis A. Shirriff came together in a partnership and formed a wine company in Toronto, Ontario. As the company began to prosper the gentlemen decided to move the location to Niagara, Ontario. Sixteen years later the Niagara Falls Wine Company opened on Dorchester Road. In 1911, Bright bought out all of Shirriff’s shares in the company and the name became the T. G. Bright and Co. Limited. A few years later in 1933 Harry C. Hatch bought the wine company from the Bright family and began changing how Bright’s operated through greater, more diverse wine production, as well as research and development. Bright’s leadership in wine research and development in Canada helped bring Canadian wines to their position of respect around the world. In 1934 Bright’s began a viticultural and vinicultural program, changing the way the Canadian wine industry worked. They put more money into research and development than any other winery in all of Canada. Soon, gold medals and “best of class” international designations were being awarded to Bright’s wines. As a result of their success, the founders soon discovered that they needed additional money to develop their business. So they borrowed money from a local bank and other lenders, or creditors, and used the funds to expand the business. Subsequent acquisition of other companies and consolidations in the wine industry led to the creation of Vincor International in 1993. Today, Vincor has established itself as a major participant in the North American super-premium wine market. By acquiring other companies, Vincor has fuelled growth in its sales from $114 million in 1995 to $654 million in 2005. The company’s success attracted the attention of its competitors. On September 27, 2005, Constellation Brands, Inc. announced its intention to buy Vincor and subsequently acquired the company in June 2006.

La caractérisation neuromagnétique de l'attention sans réflexion chez les méditants zen dans un contexte d'images visuelles négatives.

L’état d’attention sans réflexion, aussi appelé « mindfulness », a démontré des effets positifs en clinique pour les désordres émotionnels associés à diverses conditions. Le nombre d’études portant sur la caractérisation des substrats neuronaux de cet état attentionnel croît, mais il importe d’investiguer davantage à ce chapitre pour éventuellement améliorer les interventions cliniques. La présente étude compte aider à déterminer, par la magnétoencéphalographie, quelles régions cérébrales sont en corrélation avec le mindfulness chez des experts, i.e. des méditants Zen. Ces derniers cultivent un état dans lequel ils s’abstiennent de rechercher ou de rejeter les phénomènes sensoriels, ce qui en fait d’excellents candidats à la présente étude. Dans un contexte de stimulations visuelles émotionnelles, il fut demandé aux méditants tantôt d’observer les images dans un état de mindfulness (condition expérimentale), tantôt dans un état dit normal (condition contrôle) où aucun effort particulier d’attention n’était requis. Les résultats d’analyse suggèrent que les participants expérimentèrent une intensité émotionnelle moins importante en mindfulness : les cotes subjectives ainsi qu’une réponse magnétique cérébrale reliée aux émotions nommée Potentiel Positif Tardif magnétique (PPTm) suggèrent cela. Cependant, le résultat le plus statistiquement probant dépasse la nature affective des stimuli. Il s’agit d’une diminution temporellement soutenue de l’activité de fréquence gamma au niveau des zones visuelles associatives du lobe temporal droit, sans égard à la nature des images. Également, une suppression de l’activité gamma d’une zone du cortex préfrontal latéral gauche fut observée. Ceci pourrait indiquer une diminution de la conceptualisation des stimuli reliée au langage et aux processus réflectifs du soi.

Attention! Prêt? On s’enTraine! Étude d’efficacité d’un programme d’entraînement intensif des processus attentionnels chez des jeunes ayant subi un traumatisme craniocérébral

Les dysfonctions attentionnelles suivant un traumatisme craniocérébral (TCC) compliquent souvent la reprise des activités de la vie quotidienne et influencent négativement le pronostic de réinsertion socio-académique et professionnelle. Or, les cliniciens de réadaptation disposent d’un nombre limité d’outils de remédiation cognitive dont l’efficacité est démontrée et qui sont adaptés à une population francophone. Cette étude vise à démontrer l’efficacité d’un protocole d’entrainement intensif des fonctions attentionnelles : « Attention! Prêt? On s’enTraine! » (Séguin, Lahaie & Beauchamp, 2012), basé sur une adaptation française de l’« Attention Process Training-I » (APT-I; Sohlberg & Mateer, 1987). Dix-sept participants ayant subi un TCC et présentant des déficits attentionnels ont reçu 15 séances d’entrainement attentionnel avec le programme « Attention! Prêt? On s’enTraine! » (n = 8) ou de l’aide aux devoirs (n = 9). Suite à l’intervention, les participants du groupe expérimental ont amélioré leur rendement dans plusieurs fonctions ciblées par l’intervention attentionnelle, notamment au niveau du balayage visuel, de l’attention sélective et de l’alternance attentionnelle. De plus, les gains se sont généralisés à des fonctions connexes, puisqu’une meilleure performance a été retrouvée dans des tâches de mémoire de travail, d’inhibition, de flexibilité cognitive et de planification visuoconstructive. La démonstration de l’effet positif d’un entrainement intensif sur le rendement attentionnel pourrait inciter les cliniciens et chercheurs à développer et à valider d’autres protocoles de remédiation cognitive francophones, pour les fonctions attentionnelles ou d’autres sphères de la cognition. Par le fait même, le pronostic fonctionnel de la clientèle pédiatrique en traumatologie en sera potentialisé.

Limited sampling strategies for estimation of cyclosporine exposure in pediatric hematopoietic stem cell transplant recipients : methodological improvement and introduction of sampling time deviation analysis.

Le suivi thérapeutique est recommandé pour l’ajustement de la dose des agents immunosuppresseurs. La pertinence de l’utilisation de la surface sous la courbe (SSC) comme biomarqueur dans l’exercice du suivi thérapeutique de la cyclosporine (CsA) dans la transplantation des cellules souches hématopoïétiques est soutenue par un nombre croissant d’études. Cependant, pour des raisons intrinsèques à la méthode de calcul de la SSC, son utilisation en milieu clinique n’est pas pratique. Les stratégies d’échantillonnage limitées, basées sur des approches de régression (R-LSS) ou des approches Bayésiennes (B-LSS), représentent des alternatives pratiques pour une estimation satisfaisante de la SSC. Cependant, pour une application efficace de ces méthodologies, leur conception doit accommoder la réalité clinique, notamment en requérant un nombre minimal de concentrations échelonnées sur une courte durée d’échantillonnage. De plus, une attention particulière devrait être accordée à assurer leur développement et validation adéquates. Il est aussi important de mentionner que l’irrégularité dans le temps de la collecte des échantillons sanguins peut avoir un impact non-négligeable sur la performance prédictive des R-LSS. Or, à ce jour, cet impact n’a fait l’objet d’aucune étude. Cette thèse de doctorat se penche sur ces problématiques afin de permettre une estimation précise et pratique de la SSC. Ces études ont été effectuées dans le cadre de l’utilisation de la CsA chez des patients pédiatriques ayant subi une greffe de cellules souches hématopoïétiques. D’abord, des approches de régression multiple ainsi que d’analyse pharmacocinétique de population (Pop-PK) ont été utilisées de façon constructive afin de développer et de valider adéquatement des LSS. Ensuite, plusieurs modèles Pop-PK ont été évalués, tout en gardant à l’esprit leur utilisation prévue dans le contexte de l’estimation de la SSC. Aussi, la performance des B-LSS ciblant différentes versions de SSC a également été étudiée. Enfin, l’impact des écarts entre les temps d’échantillonnage sanguins réels et les temps nominaux planifiés, sur la performance de prédiction des R-LSS a été quantifié en utilisant une approche de simulation qui considère des scénarios diversifiés et réalistes représentant des erreurs potentielles dans la cédule des échantillons sanguins. Ainsi, cette étude a d’abord conduit au développement de R-LSS et B-LSS ayant une performance clinique satisfaisante, et qui sont pratiques puisqu’elles impliquent 4 points d’échantillonnage ou moins obtenus dans les 4 heures post-dose. Une fois l’analyse Pop-PK effectuée, un modèle structural à deux compartiments avec un temps de délai a été retenu. Cependant, le modèle final - notamment avec covariables - n’a pas amélioré la performance des B-LSS comparativement aux modèles structuraux (sans covariables). En outre, nous avons démontré que les B-LSS exhibent une meilleure performance pour la SSC dérivée des concentrations simulées qui excluent les erreurs résiduelles, que nous avons nommée « underlying AUC », comparée à la SSC observée qui est directement calculée à partir des concentrations mesurées. Enfin, nos résultats ont prouvé que l’irrégularité des temps de la collecte des échantillons sanguins a un impact important sur la performance prédictive des R-LSS; cet impact est en fonction du nombre des échantillons requis, mais encore davantage en fonction de la durée du processus d’échantillonnage impliqué. Nous avons aussi mis en évidence que les erreurs d’échantillonnage commises aux moments où la concentration change rapidement sont celles qui affectent le plus le pouvoir prédictif des R-LSS. Plus intéressant, nous avons mis en exergue que même si différentes R-LSS peuvent avoir des performances similaires lorsque basées sur des temps nominaux, leurs tolérances aux erreurs des temps d’échantillonnage peuvent largement différer. En fait, une considération adéquate de l'impact de ces erreurs peut conduire à une sélection et une utilisation plus fiables des R-LSS. Par une investigation approfondie de différents aspects sous-jacents aux stratégies d’échantillonnages limités, cette thèse a pu fournir des améliorations méthodologiques notables, et proposer de nouvelles voies pour assurer leur utilisation de façon fiable et informée, tout en favorisant leur adéquation à la pratique clinique.

Attention to health cues on product packages

The objectives of the study were (a) to examine which information and design elements on dairy product packages operate as cues in consumer evaluations of product healthfulness, and (b) to measure the degree to which consumers voluntarily attend to these elements during product choice. Visual attention was measured by means of eye-tracking. Task (free viewing, product healthfulness evaluation, and purchase likelihood evaluation) and product (five different yoghurt products) were varied in a mixed within-between subjects design. The free viewing condition served as a baseline against which increases or decreases in attention during product healthfulness evaluation and purchase likelihood evaluation were assessed. The analysis revealed that the only element operating as a health cue during product healthfulness evaluation was the nutrition label. The information cues used during purchase likelihood evaluation were the name of the product category and the nutrition label. Taken together, the results suggest that the only information element that consumers consistently utilize as a health cue is the nutrition label and that only a limited amount of attention is devoted to read nutrition labels during purchase likelihood evaluations. The study also revealed that the probability that a consumer will read the nutrition label during the purchase decision process is associated with gender, body mass index and health motivation.

Who knows best? Awareness of divided attention difficulty in a neurological rehabilitation setting

Objective: To explore whether patients relearning to walk after acquired brain injury and showing cognitive-motor interference were aware of divided attention difficulty; whether their perceptions concurred with those of treating staff. Design: Patients and neurophysiotherapists (from rehabilitation and disabled wards) completed questionnaires. Factor analyses were applied to responses. Correlations between responses, clinical measures and experimental decrements were examined. Results: Patient/staff responses showed some agreement; staff reported higher levels of perceived difficulty; responses conformed to two factors. One factor (staff/patients alike) reflected expectations about functional/motor status and did not correlate with decrements. The other factor (patients) correlated significantly with dual-task motor decrement, suggesting some genuine awareness of difficulty (cognitive performance prioritized over motor control). The other factor (staff) correlated significantly with cognitive decrement (gait prioritized over sustained attention). Conclusions: Despite some inaccurate estimation of susceptibility; patients and staff do exhibit awareness of divided attention difficulty, but with a limited degree of concurrence. In fact, our results suggest that patients and staff may be sensitive to different aspects of the deficit. Rather than 'Who knows best?', it is a question of 'Who knows what?.

Polymorphisms in dopamine system genes are associated with individual differences in attention in infancy

Knowledge about the functional status of the frontal cortex in infancy is limited. This study investigated the effects of polymorphisms in four dopamine system genes on performance in a task developed to assess such functioning, the Freeze-Frame task, at 9 months of age. Polymorphisms in the catechol-O-methyltransferase (COMT) and the dopamine D4 receptor (DRD4) genes are likely to impact directly on the functioning of the frontal cortex, whereas polymorphisms in the dopamine D2 receptor (DRD2) and dopamine transporter (DAT1) genes might influence frontal cortex functioning indirectly via strong frontostriatal connections. A significant effect of the COMT valine158methionine (Val158Met) polymorphism was found. Infants with the Met/Met genotype were significantly less distractible than infants with the Val/Val genotype in Freeze-Frame trials presenting an engaging central stimulus. In addition, there was an interaction with the DAT1 3′ variable number of tandem repeats polymorphism; the COMT effect was present only in infants who did not have two copies of the DAT1 10-repeat allele. These findings indicate that dopaminergic polymorphisms affect selective aspects of attention as early as infancy and further validate the Freeze-Frame task as a frontal cortex task.

Thinking about a limited future enhances the positivity of younger and older adults’ recall: support for socioemotional selectivity theory

Compared with younger adults, older adults have a relative preference to attend to and remember positive over negative information. This is known as the “positivity effect,” and researchers have typically evoked socioemotional selectivity theory to explain it. According to socioemotional selectivity theory, as people get older they begin to perceive their time left in life as more limited. These reduced time horizons prompt older adults to prioritize achieving emotional gratification and thus exhibit increased positivity in attention and recall. Although this is the most commonly cited explanation of the positivity effect, there is currently a lack of clear experimental evidence demonstrating a link between time horizons and positivity. The goal of the current research was to address this issue. In two separate experiments, we asked participants to complete a writing activity, which directed them to think of time as being either limited or expansive (Experiments 1 and 2) or did not orient them to think about time in a particular manner (Experiment 2). Participants were then shown a series of emotional pictures, which they subsequently tried to recall. Results from both studies showed that regardless of chronological age, thinking about a limited future enhanced the relative positivity of participants’ recall. Furthermore, the results of Experiment 2 showed that this effect was not driven by changes in mood. Thus, the fact that older adults’ recall is typically more positive than younger adults’ recall may index naturally shifting time horizons and goals with age.

Strategies to develop divided attention skills through video game training

Research .over the past two decades has confirmed the learning opportunities that video games can offer. The objectives of the current study were to investigate the ability of video games to enhance divided attention skills and compare these skills based on individuals' level of expertise in video game playing. Female participants aged between 17-25 years categorised as experts or novices, were divided into experimental and control groups. All participants completed the pre and post-test of divided attention between which only the experimental group received video game training. Results indicate that participants who received video game practice achieved an increase in their dual-attention skills compared to those who did not receive any training, with novices displaying a greater
enhancement in perfonnance. Implications include the provision of video game training to enhance divided attention skills in air pilot training, driving, and heavyequipment operation apart from other tasks necessitating dual-task efficiency.

Training divided attention and memory skills of older adults

The study examined whether divided attention and memory skills of older adults could be improved through video game training. The findings show that limited training with the games cannot enhance these skills. However, greater amounts of training could improve these vital skills amongst older adults.

Repetitive transcranial magnetic stimulation of the dorsolateral prefrontal cortex affects divided attention immediately after cessation of stimulation

Transcranial magnetic stimulation has evolved into a powerful neuroscientific tool allowing to interfere transiently with specific brain functions. In addition, repetitive TMS (rTMS) has long-term effects (e.g. on mood), probably mediated by neurochemical alterations. While long-term safety of rTMS with regard to cognitive functioning is well established from trials exploring its therapeutic efficacy, little is known on whether rTMS can induce changes in cognitive functioning in a time window ranging from minutes to hours, a time in which neurochemical effects correlated with stimulation have been demonstrated. This study examined effects of rTMS on three measures of executive function in healthy subjects who received one single rTMS session (40 trains of 2 s duration 20 Hz stimuli) at the left dorsolateral prefrontal cortex (DLPFC). Compared to a sham condition one week apart, divided attention performance was significantly impaired about 30-60 min after rTMS, while Stroop-interference and performance in the Wisconsin Card Sorting Test was unaffected after rTMS. Repetitive TMS of the left DLPFC, at stimulation parameters used in therapeutic studies, does not lead to a clinically relevant impairment of executive function after stimulation. However, the significant effect on divided attention suggests that cognitive effects of rTMS are not limited to the of acute stimulation, and may possibly reflect known neurochemical alterations induced by rTMS. Sensitive cognitive measures may be useful to trace those short-term effects of rTMS non-invasively in humans.

Intra-subject variability in attention-deficit hyperactivity disorder

BACKGROUND: This study is based on a comprehensive survey of the neuropsychological attention-deficit hyperactivity disorder (ADHD) literature and presents the first psychometric analyses of different parameters of intra-subject variability (ISV) in patients with ADHD compared to healthy controls, using the Continuous Performance Test, a Go-NoGo task, a Stop Signal Task, as well as N-back tasks. METHODS: Data of 57 patients with ADHD and 53 age- and gender-matched controls were available for statistical analysis. Different parameters were used to describe central tendency (arithmetic mean, median), dispersion (standard deviation, coefficient of variation, consecutive variance), and shape (skewness, excess) of reaction time distributions, as well as errors (commissions and omissions). RESULTS: Group comparisons revealed by far the strongest effect sizes for measures of dispersion, followed by measures of central tendency, and by commission errors. Statistical control of ISV reduced group differences in the other measures substantially. One (patients) or two (controls) principal components explained up to 67% of the inter-individual differences in intra-individual variability. CONCLUSIONS: Results suggest that, across a variety of neuropsychological tests, measures of ISV contribute best to group discrimination, with limited incremental validity of measures of central tendency and errors. Furthermore, increased ISV might be a unitary construct in ADHD.
