THE effects of ageing on driving related performance
No full textAccording to one estimate, about 40 percent of the driving population will be over the age of 60by the year 2020 in the UK and currently, several hundred thousand drivers with dementia holddriving licenses. The number of motor vehicle crashes per unit distance of automobile travel is“U”-shaped, with risk increasing slightly between the ages of 55 and 60, but risk increasing witheach successive five-year interval. Some individuals who have mild dementia possess sufficientdriving skills to be designated as fit drivers. The most challenging assessment and decision for thephysician/licensing authority as regards fitness to drive lies in drivers who are questionablydemented or are in a state of very mild dementia.In the absence of a reliable standard protocol, some clinicians make judgment based on selfreporting,which has risks associated with it as lack of insight and judgment are potential commontraits of the population experiencing cognitive decline. Seldom is recourse made by healthprofessionals to on-road assessment as a first alternative as it requires a fee and such testingcenters are not readily available everywhere. This research addresses this issue of theidentification of cognitive tests that can be used to assess an individual’s ability to drive andespecially of those individuals that are questionably demented and are the most difficult toidentify. A younger and an older group consisting of 56 drivers in total were administered ninedifferent cognitive tests and two drives (Drive-I and Drive-II) on the STISIM driving simulator.The cognitive test ufov3 (involving the identification of a central target and simultaneously theradial localization of a peripheral target embedded in distracter triangles), which is the thirdsubtest of the UFOV (Useful Field of View) test showed the highest discriminating ability inseparating “poor-drivers” from “not-poor-drivers”, with 92.86 % of the drivers correctlyclassified. The next best discriminating ability in decreasing order of strength was that of dichoticlistening test, trail making test, rey-copy test and paper folding test. Also, age was found to be anexcellent discriminator of “poor-drivers” and “not-poor-drivers” with 91.07 % of the driverscorrectly classified. A composite cognitive measure consisting of the sum of all nine cognitivetests was not a better predictor than the ufov3 test alone; overall it was still an excellentdiscriminator, classifying 89.29 % of drivers correctly. The commonly recommended ClockDrawing test and the Trail Making test did not emerge as significant predictors of driving ability.A general driving skills linear model for prediction purposes was derived that explained 59 % ofthe variation in a general driving performance index with the ufov3 test, the dichotic listening testand the rey-recall test as significant predictors. Recommendations are made as to how this testshould be used to screen potentially at risk drivers
Quarantine Practices during Covid-19: Current Experiences and Strategic Prevention from Future Pandemics
No full textThis century has faced various pandemics within the couple of decades. These pandemics knocked global public health systems and opened up the gaps to grasp these outbreaks. Quarantine or isolation of the susceptible individuals is an ancient technique that has been proven very effective. This technique is however not practiced accurately for current pandemic of COVID-19, due to which the COVID-19 infection is re-occurring in most part of the world
The use of neuropsychological tests to study the effects of aging on driving performance in the UK
No full textResearch was conducted to identify a series of neuropsychological tests to assess the ability to drive. Driving performance of young and old UK drivers was modeled through multiple linear regression and univariate logistic regression tools. The UFOV3 test (i.e. the third subtest of the UFOV test) had comparatively high discriminating ability in separating poor-drivers from not-poor-drivers, with 92.86% of the drivers correctly classified; the UFOV3 test resulted in a Sensitivity of 62.5%. Age and a composite cognitive measure were also found to be sound discriminators of poor-drivers and not-poor-drivers with 91.07% and 89.28% of the drivers correctly classified respectively; both age and the composite cognitive measure resulted in a Sensitivity of 50%. It was found that the commonly recommended Clock Drawing Test and the Trail Making-B test were insignificant predictors of driving ability. Results suggest that for a score greater than 220 on the UFOV3 test, the driver may be further evaluated by a driving specialist to ascertain questionable driving behavior. Also, drivers above the age of 77 were more susceptible to exhibiting unusual driving behavior; if such drivers have UFOV3 scores greater than 220 it would be more appropriate to evaluate driving behavior through a driving specialist.</p
REGIONAL INTEGRATION IN SOUTH ASIA: UTOPIA OR REALITY?
Full text linkSouth Asia comprises almost one-quarter of the world’s population. It faces a host of disputes of varying natures, including armed conflicts, proxy wars, and religious and ethnic strife. Despite its deplorable state of human security and impoverished people, South Asia is considered the least integrated region globally. Approximately 1.99 billion people suffer in terms of energy, food, water and health security due to conflicts and hostile interstate relationships. This paper analyses the socio-political and security environment of the region and explores the impediments to regional integration. Focusing on the South Asian Association for Regional Cooperation, it highlights that the idea of regional integration cannot be realized without resolving core issues. Economic cooperation between regional countries can only be achieved if integration models like the European Union and Association of South East Asian Nations are considered with necessary deviations.

Analyzing the nexus of COVID-19 and natural resources and commodities: Evidence from time-varying causality
No full textDogan, Eyup/0000-0003-0476-5177; Luni, Tania/0000-0002-7022-1920; Majeed, Muhammad Tariq/0000-0001-9374-5025Even though a few studies have focused on natural resources and commodity sectors by considering the pandemic, they have only compared their status in pre-COVID19 to post-COVID19. None of the studies has directly examined the causal relationship between the pandemic, and natural resource index and the primary commodity-related sector indices. This study fills the gap of exploring the dynamic association between them by analyzing the causal relationship between the COVID19, and natural resources index and the primary commodity-related sectors (i.e., agribusiness, energy, and metals & mining) by applying a novel time-varying causality test on daily data from January 23, 2020, to November 12, 2021. The empirical results support the presence of time-varying causality from COVID19 to natural resources, agribusiness, energy and metals & mining. The results obtained from the rolling window algorithm support causal linkages between the variables however at several points it fails to capture the dynamics of linkages between the variables which is captured by the recursive window algorithm. The outcome is robust when the pandemic is proxied by either number of cases or deaths. Similarly, the findings obtained from heteroskedastic-robust specification also validate our findings. Several policy implications are further discussed in the study
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
DYNAMICS OF REGIONAL INTEGRATION IN SOUTH ASIA: LESSONS FROM THE EUROPEAN UNION
Full text linkRegional integration is aimed at promoting socioeconomic growth and development in a region through economic cooperation among the member states. The European Union (EU) was established to promote economic and political cooperation among member countries. EU’s unprecedented success in regional integration offers lessons for other regions. Unlike the EU, SAARC has not been successful in achieving significant economic integration among member states. Despite its potential, SAARC has been plagued by political and economic differences among member states, especially between Pakistan and India. South Asian countries are unable to boost regional integration not only because of their political differences but also due to other sub-regional and trans-regional initiatives that run anti to the spirit of regional integration under the umbrella of SAARC. India’s role towards regional integration in South Asia is considered significant being the leading nation in the region. This paper first identifies the economic and political factors that hinder regional integration in South Asia. Then, it focuses on the dynamics of successful regional integration in Europe intending to underline the lessons to be learned by the South Asian countries to boost their regional cooperation.
