Microswitch technology and contingent stimulation to promote adaptive engagement in persons with minimally conscious state: a case evaluation

This study assessed whether a post-coma woman functioning at the lower end of the minimally conscious state would (a) develop adaptive responding through the use of microswitch technology and contingent stimulation, (b) consolidate and maintain her responding over time, and (c) show evidence of response-consequences awareness (learning and discrimination). The study involved an ABABB¹CB¹ sequence in which the A represented baseline phases, the B and B¹ intervention phases, and the C a control phase with continuous stimulation. Results indicated that the woman developed adaptive responding and consolidated it over the intervention phases of the study. The woman also showed evidence of being aware of response-consequences links. Potential implications and limitations of these findings are discussed.     

On the time course of exogenous cueing effects in bilinguals: higher proficiency in a second language is associated with more rapid endogenous disengagement

Previous investigations have demonstrated a bilingual advantage on various aspects of executive control. It remains unclear how the language proficiency of bilinguals might relate to the mechanisms involved in attentional disengagement. In the present investigation, we tested the hypothesis that high bilingual proficiency would lead to a more rapid endogenous disengagement of attention from task-irrelevant peripheral cues. We predicted that more rapid attentional disengagement would result in an earlier appearance of inhibition of return (IOR). In this study Hindi-English bilinguals who differed in their L2 (English) proficiency participated in a target detection task. Visual targets were preceded by uninformative peripheral cues at various stimulus onset asynchronies (SOAs) allowing for us to visualize the time course of cue-related facilitation and inhibition. High-proficient Hindi-English bilinguals showed an earlier appearance of IOR than did low-proficient bilinguals, suggesting increased efficiency in disengagement of attention from task-irrelevant inputs. Furthermore, consistent with the "global" advantage that characterizes bilinguals in many tasks, the high-proficient group outperformed low-proficient bilinguals in overall reaction time.

Socio-Demographic Variables Affecting Well-Being: A Study on Indian Rural Women

The women in Indian villages perform multiple roles that include looking after the various needs of the family members, participating in home bound income generating activities (e.g. animal husbandry, agricultural activities) and holding jobs outside the home. Against this backdrop this study addressed two related goals: (a) to understand the perception of the dual role by the rural women, their work status and preferences and the attitude of their families and society towards women and (b) to explore variation in their well-being as a function of chronological age, level of education and work status. A large sample of 221 rural women (age range 18 to 56 years) drawn from villages of Haryana participated in the study. The relevant data were obtained through interview and observation. The findings showed that family and society appreciated the efforts of the rural women. Age and level of education emerged as significant factors in determining the experience of well-being.     

Condoms,Sex, and Sexually Transmitted Diseases: Exploring Sexual Health Issues Among Asian-Indian College Students

Sexually transmitted infections (STIs) continue to pose a serious risk to college students in the US. According to the Centers for Disease Control, the highest rates of STIs are among college students and adolescents. Specifically regarding Asian-Indian students, more research is needed to thoroughly understand the knowledge, attitudes and sexual behaviors of this population. A comprehensive review of the literature found a paucity of studies involving Asian-Indian involvement in sexual activity. Therefore, the present study was undertaken to fill gaps in the research. The present study examined Asian-Indian college students’ involvement in sexual behaviors, overall STI knowledge, condom use rate, perceived benefits and barriers to condom use, and history of STIs and STI testing. A five page survey was completed by 122 Asian-Indian college students. Results indicated that overall STI knowledge was low. Females, students who perceived fewer barriers to condom use and students who had lived in the US for at least 3 years held significantly higher STI knowledge levels than their counterparts. Such findings could be used by community and university-based health educators to more effectively serve the needs of Asian-Indian students.     

Effects of hearing and vision impairments on the Montreal Cognitive Assessment

Many standardized measures of cognition include items that must be seen or heard. Nevertheless, it is not uncommon to overlook the possible effects of sensory impairment(s) on test scores. In the current study, we investigated whether sensory impairments could affect performance on a widely used screening tool, the Montreal Cognitive Assessment (MoCA). Three hundred and one older adults (mean age = 71 years) completed the MoCA and also hearing and vision tests. Half of the participants had normal hearing and vision, 38% impaired hearing, 5% impaired vision, and 7% had dual-sensory impairment. More participants with normal sensory acuity passed the MoCA compared to those with sensory loss, even after modifying scores to adjust for sensory factors. The results suggest that cognitive abilities may be underestimated if sensory problems are not considered and that people with sensory loss are at greater risk of cognitive decline.     

Research Agenda to Facilitate Community Participation In HIV Vaccine Research: A Participatory Approach

This article reports on a participatory process to generating a research agenda to guide research on community participation in HIV vaccine research. Community members representing stakeholder parties involved in the HIV vaccine research enterprise were invited to participate in the process. Fourty-five participants participated in the process and we used interactive techniques to stimulate discussion and interaction between community members at different levels of the HIV vaccine research enterprise. Through the process we generated a locally grounded research agenda to guide research on community participation in HIV vaccine research that originates out of the experiences, challenges and concerns of community members.     

Facing the third millennium: An evolutionary crisis

We are witnessing the birth of the first global civilization on our planet earth due to the accelerative progress of science and technology. This is also accompanied by a crisis in health care, pollution and other environmental disasters, a rising wave of violence and crime, stresses due to globalization, and so on. Recently, we formulated “An Action Plan for Human Survival” (Reference 24).

This article explores in depth the challenges in bringing about a peaceful transition to a global civilization. It explores global civilization, environmental crisis and population. It reveals that the stresses generated by globalization and environmental crisis cannot be resolved by dualistic thought, or concepts, or ideals, or intellectual constructions; as these are sterile in bringing mutation in the human psyche. We see that the emergence of global consciousness is not keeping pace with the globalization, and it is feared that globalization may turn out to be abortive and ultimately self‐destructive.

The crisis is not political, or economic, or social. It is evolutionary in character. We have to explore nature's evolutionary impulse. The challenge is to resolve the “crisis of perception,” or to allow the mutation to happen in the mind‐brain system. The only technology for radical transformation or mutation of human psyche is purification or deconditioning of the human psyche. This leads to new relationship between man and man, and between man and environment. It ends all pain, sorrow and travails and ushers a new era of freedom, peace and bliss. This is the key to human survival, progress and fulfillment.     

Ductility enhancement in nanoglass: role of interaction stress between flow defects

Using a thermodynamically consistent non-local plasticity model, the mechanistic origin of enhancement in ductility and suppression of dominant shear banding in nanoglasses (NGs) is analysed. It is revealed that the interaction stress between flow defects plays a central role in promoting global plasticity of NGs. Specifically, we find that the intrinsic length associated with this stress provides a scaling for the shear band width and its coupling with grain size governs the level of enhancement in the deformation behaviour of NGs. The present work may provide useful insights in developing highly ductile NGs for practical engineering applications.
