Abstract:
Baseline alertness as the strongest predictor of employment status in patients with MS 6 months after rehabilitationS. Marchione, C. Dettmers, A. Weimer-Jaekel, B. Godde, M. JoebgesAbstractIntroduction: Fatigue is a dominant impairment in multiple sclerosis, which often also limits the professional performance of patients with MS (PwMS). In clini-cal practice fatigue is often difficult to assess. The question of our study was whether the objective cognitive fatigability – measured as reaction time or tonic alertness – or the subjective self-assessment of the patient – recorded by the Fatigue Scale for Motor and Cognitive Functions (FSMC) – predicts employment status 6 months after discharge from rehabilitation.Methods: PwMS whose rehabilitation measures were paid for by the government pension fund, and who had doubts about maintaining their professional per-formance in terms of their workload, underwent further testing. Tonic alertness from the test battery TAP-M was used as an indicator of cognitive fatigability. Participants were tested in the morning at 8:00 a.m., after standardized exer-cise at 11:00 a.m., and in the afternoon at 2:00 p.m. In addition, fatigue was determined using a self-assessment questionnaire (FSMC). Six months after discharge from neurological rehabilitation, their employment status was classi-fied through a telephone interview and also compared with our socio-medical performance assessment. Results: A complete data set was collected from 64 patients (43 female; age 48.9 ± 8.7 years; duration of illness 14.7 ± 9.5 years; EDSS 3.8 ± 1.3; 67 % relapsing remitting, 16 % secondary progressive, 17 % primary progressive). According to the International Standard Classification of Occupations (ISCO) code, 86 % were “white collar” workers, for example, in service, office and non-manual jobs. Six months after discharge from the rehabilitation clinic, 15 (23 %) out of 64 PwMS reported working less than 3 hours per day, 35 (55 %) PwMS reported 3 to 6 hours, and the remaining 14 (22 %) PwMS were full-time employees. The mean total value of the FSMC questionnaire for cognition was 38.9 ± 7.4, which was equivalent to severe cognitive fatigue. Eleven of the 14 full-time employees had severe fatigue. The morning alert-ness measurement (alertness1) (β = -.985; p= .003) and, the decline in alert-ness from morning to noon (alertness difference21; β = -.590; p= .033) and from noon to afternoon (alertness difference32; β =-.709; p= .020) were sig-nificant predictors for employment status. A reduction in alertness (increase in reaction time) by 1 SD on the alertness scale increases the probability of not working full-time by a factor of 2.67. Likewise, the probability of not working full-time increases by a factor of 1.80 if fatigability is increased by 1 SD from morning to noon. If fatigability increases by 1 SD from noon to eve-ning, the probability of not working full-time increases by a factor of 2.03. Discussion: The FSMC has no prognostic value for employment status 6 months after discharge from rehabilitation. The morning alertness measurement has the highest predictive value. However, an above average decline in alertness over the course of the day also reduces the probability of working full-time.

Abstract:
Drowsy driving is one of the major problems which has led to many road accidents. Electroencephalography (EEG) is one of the most reliable sources to detect sleep on-set while driving as there is the direct involvement of biological signals. The present work focuses on detecting driver’s alertness using the deep neural network architecture, which is built using ResNets and encoder-decoder based sequence to sequence models with attention decoder. The ResNets with the skip connections allow training the network deeper with a reduced loss function and training error. The model is built to reduce the complex computations required for feature extraction. The ResNets also help in retaining the features from the previous layer and do not require different filters for frequency and time-invariant features. The output of ResNets, the features are input to encoder-decoder based sequence to sequence models, built using Bi-directional long-short memories. Sequence to Sequence model learns the complex features of the signal and analyze the output of past and future states simultaneously for classification of drowsy/sleepstage-1 and alert stages. Also, to overcome the unequal distribution (class-imbalance) data problem present in the datasets, the proposed loss functions help in achieving the identical error for both majority and minority classes during the raining of the network for each sleep stage. The model provides an overall-accuracy of 87.92% and 87.05%, a macro-F1-core of 78.06%, and 79.66% and Cohen's-kappa score of 0.78 and 0.79 for the Sleep-EDF 2013 and 2018 data sets respectively.

Abstract:
The emergence of opportunity is based on the intentions which are the result of people’s belief and the way of thinking. Entrepreneurial alertness is considered vital for identifying the opportunity which can have an impact on mindset for exploiting the opportunities. The objective of this study was to analyze the connection between opportunity identification and intentions formation through entrepreneurial alertness based on the theory of planned behavior. The data was collected from the 499 final year business students of nine universities from Sindh, Pakistan using cross-sectional survey. The results of this study revealed that entrepreneurial alertness has positive and significant effect on attitude, subjective norms, perceived behavioral control and entrepreneurial intentions. The findings of this study contributed to the theory of planned behavior by taking entrepreneurial alertness as a predictor of entrepreneurial intentions. The findings also have implication for increasing the supply of entrepreneurial capital into the society.

Abstract:
Unilateral neglect, a common consequence of a stroke, involves a difficulty with detecting and responding to contralesional stimuli. It has been shown to be a heterogeneous syndrome, involving a cluster of deficits in both spatial and nonspatial functions. Studies have shown that patients with neglect can suffer from problems with sustained attention, spatial working memory, temporal processing, and alertness, as well as the more obvious deficits in spatial orienting. One of the most intriguing features of neglect is the widely observed hemisphere lateralisation of the disorder. Neglect is more common, and more persistent, after right hemisphere lesions. Attempts to explain this lateralisation have generally focussed on hemispheric differences in the control of spatial attention. Kinsbourne (1987), for example, suggests that the right hemisphere controls the ability to orient attention to both sides of space, whilst the left hemisphere is only able to orient attention to the right side of space. An alternative theory is that the right hemisphere is specialised for the control of certain nonspatial functions, and it is the presence of deficits in these right hemisphere-lateralised functions which exacerbates spatial orienting in patients with unilateral neglect. This thesis explores this latter hypothesis and its implications, using a variety of techniques, including psychophysiology, neuropsychology, functional neuroimaging, and psychopharmacology. The central hypothesis of the thesis is that there is a direct link between nonspatial factors and spatial awareness, such that declining alertness or reduced cognitive resources may be sufficient to induce a rightward shift in spatial bias.

Abstract:
In this study, the relationship between age, sleep, and health in a group of shiftworking nurses was investigated. The study forms part of a larger study into the health and well-being of shiftworking nurses and midwives in England and Wales (Department of Health, 1993). First the importance of the relation between age and sleep was considered. Next, the impact of two important moderating variables, shiftwork and gender (roles), was examined. The nurses worked two very different shift systems: permanent night shifts or rotating shifts. The gender distribution in the sample was very skewed, which resulted in the inclusion of gender roles as variables. Having established the relative importance of the three variables, the next step was to investigate effects of the relation between the variables. Reduced alertness was the most important acute effect considered. Health and well-being complaints were considered as the main chronic effects. It was concluded that age has an important impact on sleep. The results however contradicted the dominant view in the literature that with age sleep always deteriorates. It was important to distinguish between sleep quantity and sleep quality. Both shiftwork and gender (roles) moderated the negative impact of age. Alertness was affected in a counterintuitive manner: older nurses reported feeling more alert compared to younger nurses. With regard to health and well-being, again results were surprising: health and well-being appeared to be more affected by reported sleep quality than by sleep duration. The results from this study were more varied and less linear than could have been assumed on the basis of the literature. It is argued that research should beware of unjust generalisations and move away from simple dichotomies and allow for a more varied and colourful picture.

Full text
Abstract:
Chewing gum has previously been found to reduce chronic stress and enhance alertness, but effects on attention have been less reliable. The aim of this thesis was to investigate possible mechanisms for such effects, and to study the reliability and timing of effects in greater detail. Two surveys provided detailed information about habitual gum consumption. Two intervention studies involved chewing gum during a workday and reporting well-being and performance at work; the second intervention also assessed physiological variables. Six experiments studied the timing of and mechanisms for acute chewing gum effects. Two of these experiments studied the prevalence of time-on-task trends in gum effects on attention and mood. A further experiment studied the effects of gum on mood in the absence of attention tasks. The final three experiments examined possible mechanisms for consistent effects of gum on alertness and variable effects on attention: the first concerned psychophysiology, the second concerned demand characteristics, and the third concerned rate of chewing and task order. The results of this thesis suggest that chewing gum can reliably maintain alertness and enhance reported performance at work. Chewing gum also moderated decrements in vigilance, although the direction of this effect depended on length of prior performance. A reduction of stress and anxiety was observed in some cases, but this finding was less reliable. Under experimental conditions, heart rate increased while chewing gum and began to slow following chewing, suggesting a physiological mechanism for both enhanced alertness and reduced stress. However, heart rate did not differ over the course of a workday. Salivary cortisol was higher during the morning when chewing gum, suggesting an endocrine response associated with higher alertness. Demand characteristics moderated reported alertness, but did not explain any effects on attention. Neither rate of chewing nor task order moderated chewing gum effects.

Abstract:
A novel approach for estimating alertness levels from speech and tagging them with a reliability component has been developed. The Fatigue Quotient and Believability are both derived from the time series analysis of the speech signal in the communication between the operator and dispatch. Operator attention is the most important human factor element for safe transportation operations. In addition to substance abuse, illness and intoxication fatigue is a major contributing factor to the decrease of attention. The goal of this study was to develop a means to detect and estimate fatigue levels of railroad operating personnel during on-duty hours. This goal continues to gain importance with new efforts from the government to expand rail transportation operations as a tool for high speed mass transportation in urban areas. Previous research has shown that sleeping disorders, reduced hours of rest and disrupted circadian rhythms lead to significantly increased fatigue levels which manifest themselves in alterations of speech patterns as compared to alert states of mind. In this study vocal indicators of fatigue are extracted from the speech signal and Fuzzy Logic is used to generate an estimate of the cognitive state of the train conductor. The output is tagged with a believability metric based on its behavior with respect to previous outputs and a fully alert state. Communication between the conductor and dispatch over radio provides an unobtrusive way of accessing the speech signal through existing speech infrastructure. The speech signal is discretized and processed through a digital signal processing algorithm, which extracts speech metrics from the signal that were determined to be indicative of fatigue levels. Speech metrics include, but are not limited to, speech duration, silence duration, word production rate, phrase gap duration, number of words per phrase and speech intensity. A fuzzy logic minimum inference engine maps the inputs to an output through an empirically determined rule base. The rule base and the associated membership functions were derived from batch mode and real time testing and the subsequent tuning of parameters to refine the detection of changes in patterns. To increase the validity and transparency of the output time series analysis is used to create the believability metric. A moving average filter eliminates the short term fluctuations and determines the long term trend of the output. A moving standard deviation estimation quantifies instantaneous fluctuations and provides a measure of the difference to a nominal alertness state. A real time version of the algorithm was developed and prototyped on a generic, low cost and scalable hardware platform. Rapid Prototyping was realized through the Matlab/Simulink xPC Target toolbox which allowed for instant real time code generation, testing and modification. This testing environment together with batch mode testing was used to extensively test and fine tune parameters to improve the performance of the algorithm. A testing procedure was developed and standardized to collect data and tune the parameters of the algorithm. As a high level goal it was proven that the concept of digital signal processing and Fuzzy Logic can be utilized to detect changes in speech and estimate alertness levels from it. Furthermore, this study has proven that the framework to run such an analysis continuously as a monitoring function in locomotive cabins is feasible and can be realized with relatively inexpensive hardware. The development, implementation and testing process conducted for this project is explained and results are presented here.

Abstract:
Almost 100 years ago, Jersild (1927) published his article “Mental Set and Shift”. He borrowed this title from a book of Hollingworth and Poffenberger (1919), according to whom “shifting back and forth from one mental set, one attitude or one task to another, is a relatively ineffective mode of work.” As pointed out by Jersild, the cost of switching between activities or mental sets is, for instance, the reason for Taylor’s model of industrialization and the trend in industry toward specialization. Through specialization, the element of switch is reduced to its minimum because “the cost of shift is loss in efficiency” (Jersild, 1927). However, outside of the factory, switching between multiple tasks is a crucial part of human life and the cost of switching, consequently, impacts our everyday functioning.The main topic of this doctoral dissertation is cognitive flexibility and task switching. The task-switching paradigm requires participants to switch frequently between tasks. Therefore, it measures the capacity of our brain to adapt rapidly according to tasks and goals. Dynamic adaptation according to context and goals is encompassed in cognitive psychology and neurosciences under the term cognitive control. Consequently, the ability to switch between tasks constitutes the part of cognitive control that is needed when the current goal changes and the cognitive system has to adapt. Our experimental contribution aimed at investigating how this task-goal switching can be modulated by factors such as time, language, alertness and expertise. In this introduction, we succinctly review the vast literature about attentional systems, cognitive control and task switching. In the experimental section, we describe the cued match-to-sample task that we developed to investigate task-goal switching and present five experimental studies that address the impact of several factors on task-goal switching. In the general discussion, we summarize our results and consider their implications for cognitive-control and task-switching literatures.

The present study investigated the performance and alertness of 8 healthy male participants between the age of 31 years and 65 years old in nighttime, long duration simulated train operation. Participants completed the simulator tasks twice, once alone (single run) and once with another person in the cab (paired run), on two different nights. Various simulator tasks were used to provide measurement of performance. Objective (percentage eyelid closure and psychomotor reaction time) and subjective (self reported fatigue, workload, and stress) were used to provide measurement of alertness. No significant result was found when comparing the performance and alertness measures between single and paired runs. The result showed significant correlation between the subjective measures and also between the subjective and objective measures. A significant difference in the temporal trend of performance decrement was found between the youngest and the oldest participants.

Abstract:
Converging evidences from neurophysiological, neuropsychological and functional neuroimaging literature suggested the involvement of a large-scale fronto-parietal network in the volitional and reflexive attentional control, which enables the biological systems to select relevant portions of the input stream for facilitating processing, in order to flexibly guide behavior on the basis of internal or external goals. This system acts in tight interplay with lateralized structures deputed to the achievement and maintenance of an adequate level of arousal, and with medial frontal structures responsible for the on-line modification of action and thought in response to an ever-changing external world. This project aims at clarifying the spatio-temporal dynamics of the recruitment of these three tightly related systems (alertness, orienting and executive control) and at a better explanation of integrative effects previously reported, by means of a series of high-density electrophysiological recording experiments combined with source localization methods. Experiment 1 combined a spatial cueing paradigm with a flanker task, showing early occipital and parietal activations in response to valid cues, and a lateralized pattern of sources for the responses of the phasic alertness system to both spatially valid and spatially neutral cues; additionally, we reported behavioral, electrophysiological and functional indexes of a modulation exerted by the orienting system upon the executive control one. Experiment 2 compared lateralized shifts of attention elicited by centrally and peripherally presented spatially valid and neutral cues, in a combined cueing and go/no-go task. The results again suggested an early involvement of the selective attention system in response to the task-relevant cues, as expressed in occipito-temporal enhanced responses to the valid cues as compared to the neutral ones; additionally, lateralized superior parietal and frontal activations were recorded, concurrently with attentional shifts. Again, a modulation of the conflict monitoring/response inhibition system was observed in case of validly cued stimuli, as indexed by anticipations of the fronto-central NoGoN2 in response to non-targets preceded by valid warning signals. Experiment 3 tested the hypothesis of bidirectional modulations between the attention and control systems, by means of an integrated stop-signal/flanker task. The results showed that the selective response inhibition, required in case of incompatible flankers in the primary stimuli, interfered with the attentional switch towards the relevant stop-signals, as reflected in dimmed auditory responses to the stop-tones. All in all, the present results point toward a complex interplay among the three systems, and suggest that any interpretation of the scientific results obtained in paradigms addressing the attentional networks should account also for alertness and executive control effects, which are indirectly manipulated when capitalizing on cueing/switching paradigms.

Abstract:
A Fuzzy Logic-based algorithm has been developed for processing a series of speech metrics with the ultimate goal of estimating train conductor alertness. The output is a single metric, which directly quantifies the alertness level of the conductor. The metrics were selected based on their correlation to alertness through processed speech, but without any interpretation of the spoken words or phrases. Metrics that are used include: speech duration, silence duration, word production rate and word intensity. The assessment of these metrics is an experience and human knowledge based task, which generates the need for a mathematical model to accommodate this special circumstance. The algorithm developed here uses Fuzzy Logic to cast the human knowledge base into a mathematical framework for the alertness estimation analysis. The core of this fuzzy system is a rule base consisting of fuzzy IF-THEN rules, which are derived from the existing knowledge about the effects of sleep deprivation on alertness such as Furthermore, the rules were inferred from actual voice recordings that were taken on board a train. This data was then used to create a classification scheme to determine which pattern in the speech indicates different levels of alertness from anxiety to fatigue. The simplicity of the underlying mathematical model in this approach enables this system to compute and output an alertness metric in real-time. The nature of this algorithm allows for the use of an arbitrary number of rules to classify the alertness level and therefore provides the ability to continuously develop and extend the rule base as new knowledge emerges. The resulting algorithm is a fast, multi-input, single-output system that is able to quantify the train conductor’s alertness level anytime speech is produced.

Abstract:
This paper proposes a solution for improving the safety of rail and other mass transportation systems through operator alertness monitoring. A non-invasive method of alertness monitoring through speech processing is presented. Speech analysis identifies measurable vocal tract changes due to fatigue and decreased speech rate due to decreased mental ability. Enabled by existing noise reduction technology, a system has been designed for measuring key speech features that are believed to correlate to alertness level. The features of interest are pitch, word intensity, pauses between words and phrases, and word rate. The purpose of this paper is to describe the overall alertness monitoring system design and then to show some experimental results for the core processing algorithm which extracts features from the speech. The feature extraction algorithm proposed here uses a new and simple technique to parse the continuous speech signal coming from the communication signal without using computationally demanding and error-prone word recognition techniques. Preliminary results on the core feature extraction algorithm indicate that words, phrases, and rates can be determined for relatively noise-free speech signals. Once the remainder of the overall alertness monitoring system is complete, it will be applied to real life recordings of train operators and will be subjected to clinical testing to determine alert and non-alert levels of the speech features of interest.

Abstract:
With the latest initiative of the government to develop a high speed passenger rail system in the United States the first and most important strategic transportation goal is to “Ensure safe and efficient transportation choices. A key element of safe railroad operation is to address the issue of fatigue among railroad operating employees and how to fight it. In this paper, we are presenting a novel approach to estimating fatigue levels of train conductors by analyzing the speech signal in the communication between the conductor and dispatch. We extract vocal indicators of fatigue from the speech signal and use Fuzzy Logic to generate an estimate of the mental state of the train conductor. Previous research has shown that sleeping disorders, reduced hours of rest and disrupted circadian rhythms lead to significantly increased fatigue levels which manifest themselves in alterations of speech patterns as compared to alert states of mind. To make a decision about the level of fatigue, we are proposing a Fuzzy Logic algorithm which combines inputs such as word production rate and speech intensity to generate a Fatigue Quotient at any moment in time when speech is present. The computation of the Fatigue Quotient relies on a rule base which draws from existing knowledge about fatigue indicators and their relation to the level of fatigue of the subject. For this project, the rule base and the membership functions associated with it were derived from real time testing and the subsequent tuning of parameters to refine the detection of changes in patterns. It was successfully shown that Fuzzy Logic can be implemented to estimate alertness levels from speech metrics in real-time and that the membership functions for this purpose can be found empirically through iterative testing. Furthermore, this study has proven that the framework to run such an analysis continuously as a monitoring function in locomotive cabins is feasible and can be realized with relatively inexpensive hardware.

Abstract:
Review question / Objective: The objective the current review is to delineate the cognitive profile of SCT, particularly where it is similar to or different from ADHD-related inattention. In addition, the review will provide an analysis of methodological factors that might account for discrepancies in research findings and guidance for future studies. Condition being studied: Sluggish cognitive tempo (SCT) is a constellation of symptoms originally identified among children with the inattentive subtype of attention deficit hyperactivity disorder (ADHD-I). These symptoms include daydreaming, inconsistent alertness, hypoactivity and lethargy. Although there is considerable overlap with ADHD-I, factor analytic and convergent and discriminant validity studies suggest that SCT is a distinct construct. Moreover, there is evidence that SCT may be common in a number of other disorders, including depression and autism - suggesting that SCT might represent an important transdiagnostic construct.
