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. Keywords: fatigue, fatigability, MS, alertness, employment status, prognostic factor

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:

Purpose Entrepreneurial alertness is a key factor in business opportunity identification. Scholars have determined that successful entrepreneurs have high levels of entrepreneurial alertness, but only a limited number of studies are available on the concept. One of the major reasons identified is the fragmented constituents and less knowledge of the components determining the level of alertness. The present study aims to integrate the varied research on entrepreneurial alertness, identify its core components and develop the understanding of the concept of entrepreneurial alertness. Design/methodology/approach The study is based on a systematic review of secondary research. The first stage involved identifying relevant publications and applying practical screening. In the second stage, the resources were screened for the inclusion criteria, and in the final stage, the articles meeting the inclusion criteria were read in detail for the final analysis. Findings The review resulted in identification of the following core components of the alertness construct – sensing and searching information, cognitive ability, personality factors (like creativity and self-efficacy), environment, social networks, knowledge and experience. The review also highlighted that cognitive ability plays a central role in alertness. Originality/value Based on the review of literature, the study proposes a model of the alertness construct, which attempts to draw a relationship between the identified components. The review also uncovers several unexplored areas, which still need to be addressed in the area of entrepreneurial alertness.

Abstract:

This paper critically examines Tomlin and Villa's (1994) fine-grained analysis of attention and Leow's (1998) attempt to operationalize their model. Our position is that whereas Tomlin and Villa have moved the attention research forward by describing the nature of attentional processes and by pointing out that detection is a critical function of SLA, their claim that alertness and orientation are not necessary for detection to occur is currently unsupportable and does not reflect the complex nature of SLA. We argue that Leow's efforts to provide empirical support for this model fall short of that goal. Additionally, we cast doubt on Tomlin and Villa's position that awareness is not required for the detection of L2 data by arguing that the issue of awareness as well as the role of attentional functions must be viewed from a more interactive perspective in terms of the nature of the task, the nature of the linguistic item, and individual learner differences. We conclude by proposing research orientations that may help advance the discussion on this topic.

Abstract:

With today’s fast paced lifestyles, 24*7 activity and an increasing screen-time at night, sleep disorders are widespread. Indians are not getting enough sleep in both urban as well as rural India. Sleep loss and related disorders are a silent epidemic affecting adults as well as children. The objective of the current study was to investigate the overall impact of hours of sleep and sleep quality on the cognitive alertness of the research scholars and the psychomotor vigilance Test (PVT) was used to measure the cognitive alertness. The final results of the study show that even though the research scholars are getting the required amount of sleep, their cognitive alertness is still affected and they are indeed suffering from sleepiness.

Abstract:

Entrepreneurial alertness can play a vital role in the identification and creation of opportunities involving early-stage ventures. However, the strategic function of entrepreneurial alertness in more mature organizations has not been explored. In a field study of organizations responding to an environmental disruption, we explore if entrepreneurial alertness influences decisions involving the creation and maintenance of competitive advantage. We find a direct effect of entrepreneurial alertness on strategic change decisions and organizational performance. Moreover, we find a synergistic influence of entrepreneurial alertness and other cognitions, including issue categorization and assessments of uncertainty, on strategic decisions. Findings demonstrate that managerial decision makers can take multiple, reinforcing pathways when heeding change.

Abstract:

This article uses theoretical approaches from cognitive psychology to examine the basis for entrepreneurial alertness and to connect it to existing theories of attention in strategic management and decision-making. It thereby provides a theoretical basis for understanding how entrepreneurial alertness leads the individual to pay attention to new opportunities. A model is developed to show how attention and entrepreneurial alertness work together to support the recognition or creation of opportunities. Entrepreneurial alertness is believed to be a manifestation of differences in the schemata and cognitive frameworks that individuals use to make sense of changes in the environment. This suggests that entrepreneurial alertness mediates the impact of observed phenomena upon the situated attention of individual decision-makers.

Abstract:

Light is known to elicit non–image-forming responses, such as effects on alertness. This has been reported especially during light exposure at night. Nighttime results might not be translatable to the day. This article aims to provide an overview of (1) neural mechanisms regulating alertness, (2) ways of measuring and quantifying alertness, and (3) the current literature specifically regarding effects of different intensities of white light on various measures and correlates of alertness during the daytime. In general, the present literature provides inconclusive results on alerting effects of the intensity of white light during daytime, particularly for objective measures and correlates of alertness. However, the various research paradigms employed in earlier studies differed substantially, and most studies tested only a limited set of lighting conditions. Therefore, the alerting potential of exposure to more intense white light should be investigated in a systematic, dose-dependent manner with multiple correlates of alertness and within one experimental paradigm over the course of day.

Abstract:

Background: Alertness and ability to perform vary as functions of homeostatic factors such as sleep duration, sleep quality, and time awake. As far as medical students are concerned, alertness during the lectures is important due to their vast curriculum, and their alertness aids in the development of better doctors in their future. Though the importance of sleep is known, there is scarcity of studies on how adequate sleep among medical students affects their alertness during lecture classes. The aim was to study effect of sleep duration on alertness among medical students from a tertiary care hospital in Thrissur district, Kerala.Methods: A cross-sectional study was conducted among undergraduate medical students and alertness was assessed following afternoon lecture classes, using a Stanford sleepiness scale questionnaire. The sample size was calculated with a formula 4PQ/d2 and total 202 undergraduate students were included. The data regarding overnight sleep duration and post lunch nap was also collected using a semi-structured questionnaire.Results: Based on stanford sleepiness scale 66.3% of students were alert and responsive, 29.2% were not alert and only 4.5% of students were sleepy following afternoon lecture classes. Out of total 202 undergraduate students 43.6% of them had poor overnight sleep and only 32.7% had taken post lunch nap. There was a statistically significant association between alertness and post lunch nap (p=0.01).Conclusions: Those students who had good overnight sleep and post lunch nap had better alertness during lecture classes.

Abstract:

Opportunity recognition has been widely viewed as a key step in the entrepreneurial process. Two major perspectives that address opportunity recognition offer diametrically opposed predictions: systematic search versus entrepreneurial alertness employed to identify opportunities. Instead of treating alertness and search as contradictory concepts, the current research uses a traditional Chinese philosophy and folklore, the yin and yang perspective and its competing yet reconciling forces, to suggest that the dynamic interaction between alertness and systematic search will increase the chances and improve the effectiveness of opportunity discovery. An alertness/search typology of innovations is also proposed.

Abstract:

Alertness is a foundational concept in current understandings of the spotting and exploitation of entrepreneurial opportunities. In this paper its two broad aspects from psychology have been explored and a model has been generated; reflecting the hierarchical relation between alertness aspects and mindfulness factors. Results show that mindfulness mediates the relationship between alertness and novelty creation. We use Interpretive Structure Modeling (ISM) to create the model of entrepreneurial alertness and mindfulness. The model is generated on the basis of ten technological entrepreneurs in the ISM session in Iran. They voted on the mutual relations of the elements. The results showed that mindfulness fosters alertness, which then leads to the creation of novel things. This also shows that mindfulness deserves more investigation for its potential role in other parts of entrepreneurial process.

Abstract:

The influence of Chinese university students' entrepreneurial experience, alertness, and prior knowledge on opportunity recognition was examined using the novice–experienced entrepreneurs contrast paradigm. After viewing a self-made opportunity situation, 94 entrepreneurial university students and 114 nonentrepreneurial university students were instructed to complete via email or paper and pencil tests measures of opportunity recognition, entrepreneurial alertness, and prior knowledge. The results showed that entrepreneurial alertness significantly and directly predicted opportunity recognition, whereas prior knowledge significantly and indirectly affected opportunity recognition through its impact on entrepreneurial alertness. The entrepreneurial alertness of nonentrepreneurial university students significantly influenced their opportunity recognition; in contrast, the prior knowledge of entrepreneurial university students greatly influenced their opportunity recognition. Practical implications for entrepreneurial training and future directions for research on opportunity recognition are discussed.

Abstract:

The relation between college students' entrepreneurial intention and college entrepreneurial education has long been concerned. Entrepreneurial alertness is the psychological basis for entrepreneur to identify entrepreneurial opportunities. Entrepreneurial intention and entrepreneurial alertness are two key focuses in entrepreneurship research. It is of great significance to explore and investigate the role of entrepreneurial alertness in arousal process of entrepreneurial intention by entrepreneurial education.However, there are very few researches reported on the relation among entrepreneurial education, entrepreneurial alertness and entrepreneurial intention. Entrepreneurial education was measured by theBenefits from EntrepreneurialEducation Programes(BEEP). By collecting data (N=672) from colleges and universities in Zhejiang and Fujian where entrepreneurship is relatively active in China, empirical study was carried out to investigate the relation among the three variables.. The results showed that:entrepreneurial alertness plays a significant mediating and regulating role between entrepreneurial education and entrepreneurial intention. The cultivation of entrepreneurial alertness should be a key purpose of entrepreneurial education. Finally, this paper presents discussion on how to conduct targeted entrepreneurial education in order to guide college students' entrepreneurship more efficiently.

Abstract:

Broad-spectrum light applied during the night has been shown to affect alertness in a dose-dependent manner. The goal of this experiment was to investigate whether a similar relationship could be established for light exposure during daytime. Fifty healthy participants were subjected to a paradigm (0730-1730 h) in which they were intermittently exposed to 1.5 h of dim light (<10 lux) and 1 h of experimental light (24-2000 lux). The same intensity of experimental light was used throughout the day, resulting in groups of 10 subjects per intensity. Alertness was assessed with subjective and multiple objective measures. A significant effect of time of day was found in all parameters of alertness ( p < 0.05). Significant dose-response relationships between light intensity and alertness during the day could be determined in a few of the parameters of alertness at some times of the day; however, none survived correction for multiple testing. We conclude that artificial light applied during daytime at intensities up to 2000 lux does not elicit significant improvements in alertness in non-sleep-deprived subjects.

Abstract:

Alertness is a foundational concept in current understandings of the spotting and exploitation of entrepreneurial opportunities. Yet, despite being identified as a key theoretical construct of individual entrepreneurs, its cognitive features are not fully described in the literature. And as a result, the existing instruments for measuring this cognitive feature of entrepreneurs do not fully reflect the broad nature of this concept. In this study, the cognitive theoretical basis of alertness is reviewed and a new scale, which better reflects the broader cognitive features of entrepreneurial alertness, is presented. This may assist the validity of future empirical studies that involve entrepreneurial alertness.

Abstract:

While alertness is widely acknowledged as one of the most important preconditions for learning and development, individuals with profound intellectual and multiple disabilities (PIMD) experience a wide range of difficulties in the contact with their environment. The aim of the present study was to identify aspects of stimulation situations that influence the alertness levels of individuals in the target population.Based on video recordings of 24 participants, alertness levels and environmental conditions were scored. Descriptive analyses and multilevel logistic regression analysis were used to identify the aspects of the stimulation situation that were related to occurrence of alertness.The results show that visual stimuli (optimally in combination with auditory stimuli) produced the highest alertness levels. Furthermore, the effects of stimuli outweighed the effect of time. The role of direct support persons is thus especially important in alertness stimulation of individuals with PIMD.

Abstract:

Funktionelle Reorganisation nach Alertness-Training bei zwei Patienten mit Läsionen der rechten Hemisphere Zusammenfassung: Bei Patienten mit Alertness-Defiziten nach rechtshemisphärischer vaskulärer Schädigung wurde die individuelle Veränderung des funktionellen Netzwerkes für Alertness nach einem spezifischen Training in einer PET-Aktivierungsstudie untersucht. Die Patienten wurden mit dem Unterprogram Alertness aus dem computergestützten AIXTENT Aufmerksamkeitstraining behandelt. Vor und nach dem Training erfolgte jeweils eine PET- und eine neuropsychologische Untersuchung zur Erfassung von Aufmerksamkeitsstörungen und Hemineglect. In dieser Arbeit präsentieren wir zwei Patienten, von denen einer signifikante Leistungsverbesserungen nach dem Training erzielte. Bei diesem Patienten zeigte sich nach dem Training eine teilweise Restitution des rechtshemisphärischen funktionellen Netzwerks, welches sich bei Gesunden als relevant für die intrinsische Alertness-Kontrolle erwiesen hat. Bei dem zweiten Patienten, der keine Verbesserung zeigte, ergab sich nach dem Training lediglich eine deutliche linkshemisphärische Aktivierung im PET.

Abstract:

One of the benefits of physical activity in people with profound intellectual and multiple disabilities (PIMD) is an increase in alertness. This study investigated the effect of a power-assisted exercise intervention on alertness and the relationship of this effect to the level of additional motor and visual impairments in people with PIMD. A randomized controlled trial design (N = 37) was used with five measurements. Using individual plots and multilevel analysis, differences in change of alertness over time were analyzed between the intervention and control group, as was the relationship of changes to additional impairments. Considerable variation in alertness over time was found. The results showed no difference between the control and intervention groups in terms of alertness. No relationship with additional impairments was found. This study underlines the importance of looking at the effectiveness of interventions for people with PIMD because those interventions may not be as effective as expected.

Abstract:

This paper extends the conventional wisdom of social networks and entrepreneurship by clarifying the relationship between network diversity and venture growth as well as by studying the mediation effect of entrepreneurial alertness on network diversity. It highlights the importance of diverse networks for providing heterogeneous information and resources, which is the antecedent of entrepreneurial alertness. In this paper, Global Entrepreneurship Monitor (GEM) data from 44 countries are used in our analysis, considering the country’s impact. Overall, we concluded that network diversity can significantly predict entrepreneurial alertness, and a venture’s growth. Furthermore, an entrepreneur’s educational level and entrepreneurial experience have positive moderating effects on the relationship between network diversity and entrepreneurial alertness.

Abstract:

In this study, we investigated whether alertness training in healthy older adults increases visual processing speed (VPS) and whether functional connectivity in the cingulo-opercular network predicts training gain. Using the theory of visual attention, we derived quantitative estimates of VPS before and after training. In Study 1, 75 healthy older adults participated in alertness training, active-control training, or no training ( n = 25 each). A significant Group × Session interaction indicated an increase in VPS in the alertness-training group but not in the control group, despite VPS not differing significantly between groups before training. In Study 2, 29 healthy older adults underwent resting-state functional MRI and then participated in alertness training. Pretraining functional connectivity in the cingulo-opercular network correlated with the individual training-induced change in VPS. In conclusion, results indicate that alertness training improves visual processing in older adults and that functional connectivity in the cingulo-opercular network provides a neural marker for predicting individual training gain.

Abstract:

Twenty-four subjects with normal vestibular function underwent horizontal sinusoidal harmonic acceleration (SHA) and step-velocity rotational chair assessment twice, first in a heightened state-of-alertness, and second, in a low state-of-alertness. The effects of alertness on vestibulo-ocular reflex gain and time-constant (Tc) were then examined. Although the negative effect on SHA gain had previously been widely reported, the effect on the Tc had not been studied. It was found that SHA gain and step-velocity Tc were significantly and artificially reduced with decreased alertness. On average, SHA gain was reduced by 0.1 at each test frequency and the Tc was reduced from 15.8 seconds to 10.5 seconds. Whilst on average, step-velocity initial gain was only a little affected reducing from 0.53 to 0.49. This very small difference of 0.04 was significant, however, it suggested that this measurement is less affected by patient alertness than SHA gain and Tc.

Abstract:

In this paper, the pulse wave feature alertness detection system based on computer software technology is researched. First, the computer software technology designs the alertness detection system and then conducts the system alertness test experiment using a system that can not affect the subjects’ alertness, a portable multichannel physiological signal acquisition system that measures the subjects’ ECG signal, skin resistance, blood oxygen saturation, and other physiological signals in the case of a degree task experiment. The multichannel physiological signal acquisition system collects the signals during the vigilance task experiment. At the same time, before, during, and after the experiment, subjects are required to fill in the Stanford Sleepiness Scale (SSS) and evaluate the level of individual alertness through subjective self-evaluation. The relevant experimental data show that, 10 minutes before the experiment, the pulse amplitude increased rapidly, then slowly decreased at the beginning, reached a peak in about 25 minutes, and then began to rise.

Abstract:

In order to learn how mine equipment operators view numerous factors which may affect their alertness, two groups of operators (N = 57 and N = 73) were surveyed through the administration of questionnaires. It was of particular interest to use survey questions which would elucidate the hypothetical links between shift rotation, alertness, and accident causation. Based on the information and impressions obtained during this project, it seems apparent that alertness is greatly influenced by the necessity to work three shifts on a rotating schedule, by the physical and mental stimulation afforded by the task, and by the physical environment. It is also apparent that alertness can be maintained or at least restored by incorporating certain changes in the way tasks are performed and by modifying shift rotation schedules. Future Bureau of Mines research will utilize this information in designing improved shift rotation schedules and in deriving coping strategies which shiftworking mine equipment operators can use to maintain alertness on the job.

Abstract:

The purpose of the current study was to evaluate the effectiveness of different alertness maintaining tasks on driver performance. Twelve professional truck drivers participated in five sessions of simulated driving. The first session consisted of driving without any alertness-maintaining tasks. In the following three sessions, three different alertness maintaining tasks were given during the drive. The fifth session consisted of driving while listening to music. The analysis of the driving performance measures shows that overall alertness-maintaining tasks may have a positive effect on driving, by slowing performance deterioration and maintaining a higher level of alertness (measured by standardized HRV). Yet, not all tasks were equally demanding. Of the three tasks evaluated, the choice reaction time task was the least demanding and failed to prevent performance deterioration. A working memory task caused a decrement in longitudinal speed, perhaps indicating that it was too demanding for most drivers to perform while driving, and was subjectively evaluated by the drivers as the most detrimental task to the driving. A trivia game task did not show any advantage in preventing performance deterioration, but was preferred by 50% of the drivers over the other two tasks.

Abstract:

Purpose The purpose of this study is to examine how human, social and psychological capital influences women’s entrepreneurial alertness and discover if these influences are moderated by job complexity. Design/methodology/approach This is a quantitative research study using a purposive sampling method where data are gathered from a self-report survey. The hypotheses are tested using a sample of 274 female middle managers using a hierarchical moderated regression analysis. Findings The results support that women’s human and psychological capital are positively related to each dimension of their entrepreneurial alertness, and that these relationships are moderated by job complexity. Results also indicate that women’s social capital is not related to their entrepreneurial alertness. Research limitations/implications The most important limitation of this study is that it only considers women who work as middle managers in established firms without considering the specific responsibilities or duties that influence their entrepreneurial alertness and thus generalizability for other contexts may be limited. Practical implications The results show that entrepreneurial alertness represents a capability that can be learned and improved and may offer guidance to aspiring women middle managers in how to mindfully discover opportunities with business potential. Originality/value This study adds new empirical evidence that contributes to a better understanding of how women, within the context of established firms, enhance the occurrence of entrepreneurial behavior by being alert to entrepreneurial opportunities.

Abstract:

We examined the relationship between entrepreneurs' social networks and opportunity identification, and the moderating roles of entrepreneurial passion and entrepreneurial alertness in this relationship. Results from 142 entrepreneurs supported the hypothesis that both their business ties and their political ties would be positively related to opportunity identification, and these relationships would be moderated by entrepreneurial passion and entrepreneurial alertness. Entrepreneurial passion weakened the relationship between business ties and opportunity identification, but amplified the relationship between political ties and opportunity identification. Further, entrepreneurial alertness strengthened the relationship between business ties and opportunity identification. The results suggest that the effect of entrepreneurs' social ties on opportunity identification depends on the level of the individual's entrepreneurial passion and entrepreneurial alertness.

Abstract:

Background Ambulatory surgical patients are advised to refrain from driving for 24 h postoperatively. However, currently there is no strong evidence to show that driving skills and alertness have resumed in patients by 24 h after general anesthesia. The purpose of this study was to determine whether impaired driver alertness had been restored to normal by 2 and 24 h after general anesthesia in patients who underwent ambulatory surgery. Methods Twenty patients who underwent left knee arthroscopic surgery were studied. Their driving simulation performance, electroencephalographically verified parameters of sleepiness, subjective assessment of sleepiness, fatigue, alertness, and pain were measured preoperatively and 2 and 24 h postoperatively. The same measurements were performed in a matched control group of 20 healthy individuals. Results Preoperatively, patients had significantly higher attention lapses and lower alertness levels versus normal controls. Significantly impaired driving skills and alertness, including longer reaction time, higher occurrence of attention lapses, and microsleep intrusions, were found 2 h postoperatively versus preoperatively. No significantly differences were found in any driving performance parameters or electroencephalographically verified parameters 24 h postoperatively versus preoperatively. Conclusions Patients showed lower alertness levels and impaired driving skills preoperatively and 2 h postoperatively. Based on driving simulation performance and subjective assessments, patients are safe to drive 24 h after general anesthesia.

Abstract:

This paper analyzes internet banking fraud alertness to the general public by the South African banking institutions. The study is centered on routine activity theory, which is a criminology theory. A qualitative content analysis was used as the research technique for the interpretation of the text data from each bank’s website through the systematic classification process of coding and identifying themes or patterns to provide an in-depth understanding of internet banking fraud alertness in the banking sector. A sample size of 13 out of 16 locally and foreign controlled retail banks in South Africa was used. The findings report that banks are not adequately providing internet fraud alertness information to the general public on their websites notwithstanding that most banks they do provide such information to log-in users and the use of that information is doubtful. This study suggests a need to augment internet banking fraud alertness information and passably inform internet banking users of the types of internet banking fraud perpetrated by internet fraudsters before they log-in for transacting. Considering the current and widespread quandary of internet banking fraud, the information of this paper is important for internet banking users to improve their aptitude in identifying fraudulent schemes and circumvent them, and for the banking institutions to invest more in the provision of internet banking fraud information to the general public.
