The curved contour of the road creates blind spots which increase the risk of traffic accidents. Throughout 2019, there were 107,500 accident cases recorded in Indonesia. Therefore, efforts are needed to provide road infrastructure that supports driving safety, such as traffic signs to reduce the risk of accidents in blind spot areas. This research aims to design a smart safety light warning system that is integrated with solar-based street lighting. The design uses a design-based research approach referring to several established standards including Indonesia National Standard (SNI) 7931: 2008, SNI IEC 60529:2014, Regulation of the Minister of Transportation of the Republic of Indonesia Number PM 13 of 2014, Manual on Uniform Traffic Control Devices (MUTCD) issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT), and Article 115 of Minister of Transportation Republic of Indonesia Regulation PM 27 of 2018. This study used Design-Based Research (DBR) as a research methodology. The result of this study is a prototype design and development of smart safety light warning system which can be optimized. Validation of the design and circuit is conducted using prototyping modeling 1:20 from the original dimensions to measure the function and performance of the circuit. The prototype is capable of turning on warning lights and siren notifications when detecting objects with a maximum distance of 350 cm as measured by the HC – SR04 sensor. Charging the stored solar panels via the accumulator allows the technology to continue working for 45 hours without charging. For power efficiency purposes, the technology is equipped with an LDR (Light Dependent Resistor) sensor with a minimum limit of 341-lux which regulates the lighting. The development of these safety lights will increase driver awareness when passing through blind spot areas and have positive implications for reducing the number of accidents in Indonesia.

To understand the neural mechanisms of perceptual filling-in at the blind spot (BS), we analyzed neural activity in the region representing the visual field corresponding to the BS (BS region) in the primary visual cortex (V1) of the macaque monkey. We inserted a linear array electrode into the BS region or surrounding region and recorded the multiunit activities (MUAs) and local field potential (LFP). We examined the responses of MUAs and LFP to a large visual stimulus that entirely covered the BS (surface stimuli) while the monkey performed a visual fixation task in either the monocular condition without receiving direct retinal input or the binocular condition receiving retinal information. We observed clear MUA responses in the deep layers within the BS region under monocular conditions, confirming previous reports that V1 neurons in the BS region are activated when perceptual filling-in occurs. Current source density analysis using LFP showed that MUA responses were mainly observed in layer 5. Although LFP responses were generally stronger in the binocular condition than in the monocular condition, a notable exception was observed in the BS region. LFP responses in the low-beta band in the superficial layers were stronger in the monocular condition than in the binocular condition. These results suggest that low-beta activity in the superficial layer is related to the occurrence of perceptual filling-in in the BS. The origin of this activity is considered to be feedback signals from the extrastriate areas to the V1. NEW & NOTEWORTHY Two characteristic activities were induced in the blind spot (BS) region in response to the stimulus, causing perceptual filling-in: 1) beta-band LFP responses in the superficial layers and 2) neuronal responses in the deep layers, mainly in layer 5. These data suggest that the feedback signal from the extrastriate areas to the BS region in V1 is involved in perceptual filling-in. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of our study was to identify the locations at which hip and pelvic fractures are commonly missed on radiographs. Methods: A retrospective study was performed at four non-Level 1 trauma center emergency departments. IRB approval was obtained. All emergency department hip or pelvic radiographs with subsequent CT performed within 48 h were identified from 2017 to 2022. Reports for each radiograph and CT were scored for the presence or the absence of fracture in the following locations: ilium, sacrum, superior pubic ramus, inferior pubic ramus, pubis, acetabulum, subcapital femoral, femoral neck, greater trochanter, lesser trochanter, intertrochanteric, and subtrochanteric. The CT report was used as the gold standard. The false-negative radiography cases were reviewed on a PACS workstation to determine whether the case had an "unexpected miss" of a fracture, a subtle fracture, radiographically occult fracture, or exam was limited by artifact. The percentage of missed fractures at each location was calculated. Results: Nine hundred seventy-five radiography cases with subsequent CT were identified. One hundred forty-six cases did not meet entry criteria; therefore, 829 cases were analyzed further. Seventy-four percent of patients were female with age of 74 ± 16 (mean ± standard deviation) years (range 1–103). Three hundred fifty-two cases had at least one fracture, and many cases had multiple fractures. There were 68 false-negative cases. The most commonly missed fractures by percentage were pubis, ilium, and greater trochanter. The most common unexpectedly missed fractures were greater trochanter and femoral subcapital. Conclusion: A careful systematic evaluation of hip and pelvic radiographs, with particular attention to the pubis, ilium, greater trochanter, and subcapital region, may improve radiographic fracture detection and decrease delays in diagnosis.

Interest in advanced driver assistance systems (ADAS) is booming in recent years. One of the most effervescent ADAS features is blind spot detection (BSD), which uses radar sensors or cameras to detect vehicles in the blind spot area and alerts the driver to avoid a collision when changing lanes. However, this kind of BSD system fails to notify nearby vehicle drivers in this blind spot of the possible collision. The goal of this research is to design a proactive bus blind spot warning (PBSW) system that will immediately notify motorcyclists when they enter the blind spot or the area of the inner wheel difference of a target vehicle, i.e., a bus. This will increase the real-time functionality of BSD and can have a significant impact on enhancing motorcyclist safety. The proposed hardware is placed on the motorcycle and consists of a Raspberry Pi 3B+ and a dual-lens stereo camera. We use dual-lens cameras to capture and create stereoscopic images then transmit the images from the Raspberry Pi 3B+ to an Android phone via Wi-Fi and to a cloud server using a cellular network. At the cloud server, we use the YOLOv4 image recognition model to identify the position of the rear-view mirror of the bus and use the lens imaging principle to estimate the distance between the bus and the motorcyclist. Finally, the cloud server returns the estimated distance to the PBSW app on the Android phone. According to the received distance value, the app will display the visible area/blind spot, the area of the inner wheel difference of the bus, the position of the motorcyclist, and the estimated distance between the motorcycle and the bus. Hence, as soon as the motorcyclist enters the blind spot of the bus or the area of the inner wheel difference, the app will alert the motorcyclist immediately to enhance their real-time safety. We have evaluated this PBSW system implemented in real life. The results show that the average position accuracy of the rear-view mirror is 92.82%, the error rate of the estimated distance between the rear-view mirror and the dual-lens camera is lower than 0.2%, and the average round trip delay between the Android phone and the cloud server is about 0.5 s. To the best of our knowledge, this proposed system is one of few PBSW systems which can be applied in the real world to protect motorcyclists from the danger of entering the blind spot and the area of the inner wheel difference of the target vehicle in real time.

Purpose: To report the clinical and anatomical features of an unusual case of acute idiopathic blind spot enlargement syndrome (AIBSES) with retinal vasculitis. Observations: A 39-year-old patient, who was a known case of chronic headache with nonspecific visual symptoms for nine years, developed scotomas in her right eye. She was initially diagnosed with AIBSES which had been stable, but later worsened with symptoms of subsequent blind spot enlargement and photopsia on the left eye a year later. Increase in the size of the blind spot over the left eye and stability of the blind spot enlargement over the right eye was documented on Humphrey visual field (HVF) testing. Due to the rapid onset and severity of symptoms, an inflammatory etiology was entertained and this prompted referral to our clinic. At initial presentation, fluorescein angiogram (FA) revealed moderate diffuse vasculitis and disc leakage in the left eye, which existed alongside the enlarged blind spot. Corticosteroid treatment was suggested and initiated. The patient was found to have a reduction in the size of her blind spot and a decrease in severity of retinal vasculitis a month later. Unfortunately, the patient was then lost to follow up and had stopped steroid treatment of her own accord. After nine months without treatment, the patient's blind spot increased to a larger size than her initial presentation, as documented on HVF, with recurrence of vasculitis in the left eye. Conclusion and Importance: This is an unusual case of AIBSES which presented with vasculitis and rapid progression and has responded to steroids. Though monocular AIBSES has been shown to later affect the contralateral eye, concurrent vasculitis with AIBSES has not previously been reported. Furthermore, the response to treatment with reduction in blind spot enlargement is unusual for AIBSES. These findings stress the need for regular monitoring in cases of AIBSES.

The physiological blind spot is a naturally occurring scotoma corresponding with the optic disc in the retina of each eye. Even during monocular viewing, observers are usually oblivious to the scotoma, in part because the visual system extrapolates information from the surrounding area. Unfortunately, studying this visual field region with neuroimaging has proven difficult, as it occupies only a small part of retinotopic cortex. Here, we used functional magnetic resonance imaging and a novel data‐driven method for mapping the retinotopic organization in and around the blind spot representation in V1. Our approach allowed for highly accurate reconstructions of the extent of an observer's blind spot, and out‐performed conventional model‐based analyses. This method opens exciting opportunities to study the plasticity of receptive fields after visual field loss, and our data add to evidence suggesting that the neural circuitry responsible for impressions of perceptual completion across the physiological blind spot most likely involves regions of extrastriate cortex—beyond V1.

The essay is concentrated on emotional affects caused by representation of violence in the case of Russia's war against Ukraine and beyond. Instant accessibility to first-hand visual information created fertile soil for planting and then multiplying manipulative strategies of one or another political interest. Meanwhile, the demand for shocking content continues to steadily rise because it guarantees popularity, spectacle and even a form of pleasure. This, in turn, supports a very propagandistic version of reality where violence plays a central role in the overall design and transmission of contents, which is driven by shock as an affective medium. Blind Spot, Gradual Loss of Vision and Speck in the Eye represent a body of works by Mykola Ridnyi, address the question of what potential response(s) could be given by artistic interventions understood as a dialectical and critical framework able to face and make visible the problem of dehumanization through violence?

During perceptual rivalry, an observer's perceptual experience alternates over time despite constant sensory stimulation. Perceptual alternations are thought to be driven by conflicting or ambiguous retinal image features at a particular spatial location and modulated by global context from surrounding locations. However, rivalry can also occur between two illusory stimuli-such as two filled-in stimuli within the retinal blind spot. In this "filling-in rivalry," what observers perceive in the blind spot changes in the absence of local stimulation. It remains unclear if filling-in rivalry shares common mechanisms with other types of rivalry. We measured the dynamics of rivalry between filled-in percepts in the blind spot, finding a high degree of exclusivity (perceptual dominance of one filled-in percept, rather than a perception of transparency), alternation rates that were highly consistent for individual observers, and dynamics that closely resembled other forms of perceptual rivalry. The results suggest that mechanisms common to a wide range of rivalry situations need not rely on conflicting retinal image signals.

Background: The lesion detection rate of esophagogastroduodenoscopy (EGD) varies depending on the degree of experience of the endoscopist and anatomical blind spots. This study aimed to identify gaze patterns and blind spots by analyzing the endoscopist's gaze during real-time EGD. Methods: Five endoscopists were enrolled in this study. The endoscopist's eye gaze tracked by an eye tracker was selected from the esophagogastric junction to the second portion of the duodenum without the esophagus during insertion and withdrawal, and then matched with photos. Gaze patterns were visualized as a gaze plot, blind spot detection as a heatmap, observation time (OT), fixation duration (FD), and FD-to-OT ratio. Results: The mean OT and FD were 11.10 ± 11.14 min and 8.37 ± 9.95 min, respectively, and the FD-to-OT ratio was 72.5%. A total of 34.3% of the time was spent observing the antrum. When observing the body of the stomach, it took longer to observe the high body in the retroflexion view and the low-to-mid body in the forward view. Conclusions: It is necessary to minimize gaze distraction and observe the posterior wall in the retroflexion view. Our results suggest that eye-tracking techniques may be useful for future endoscopic training and education. [ABSTRACT FROM AUTHOR]

In Europe, heavy goods vehicles (HGVs) are disproportionately involved in serious and fatal collisions with vulnerable road users (VRUs). An interrogation of 2019 national crash data for Great Britain (Stats19) suggested that detection of cyclists and pedestrians in the nearside and front blind spots of HGVs is still a significant problem during forward or left-turn manoeuvres of the HGV. To improve detection, Transport for London introduced Direct Vision and Safe System Standards in 2021 for HGVs entering the Greater London area. This research assessed the efficacy of one of the Safe System requirements—the fitment of sensors to detect vulnerable road users on the nearside of the vehicle. A physical testing procedure was developed to determine the performance of a sensor system meeting the Transport for London Safe System requirements. Overall, the Safe System compliant sensor system missed 52% of expected detection nodes on the nearside of the vehicle. A total of 56% of the "stop vehicle" nodes, 45% of the "slow down" and 48% of the "proceed with caution" nodes were not recognised. The most forward sensor did not fully cover the front-left corner blind spot, missing 70% of the desired detection nodes. Nearside sensor systems fitted to Safe System requirements may cover a reasonable area but could still leave many undetected zones to the left and front of the vehicle. Standardising sensor range and location could help to eliminate sensor blind spots. Mandating additional front sensors would help cover the blind spot at the front-left corner of the HGV.

"Blind Spot--Staring Down the Void" is a French-English dialogue between Carole Nadeau and Karen Kipphoff in which they reflect on their collaboration to create a performance with four other unknown-to-each-other artists of different artistic disciplines and cultural and linguistic backgrounds. The performance was developed through workshops and presented at the Norwegian Theatre Academy, Østfold University College, in Fredrikstad, and at the 2017 Meteor Festival in Bergen, Norway. The dialogue addresses the process, outcome, and complications of the production with a focus on encounters with cultural and physical blind spots; the creation of material for a performance in a non-hierarchical, non-directed process; decision-making in a devised process; creative languages; use of devices; new materialism; drawing as performative gestures; and documentation. The performance was the first part of three--the other two being an exhibition and a publication--of the artistic research project Blind Spot: Staring Down the Void undertaken between 2016 and 2020.

Abstract Owing to its high mortality rate, the prevention of colorectal cancer is of particular importance. The resection of colorectal polyps is reported to drastically reduce colorectal cancer mortality, and examination by endoscopists who had a high adenoma detection rate was found to lower the risk of colorectal cancer, highlighting the importance of identifying lesions. Various devices, imaging techniques, and diagnostic tools aimed at reducing the rate of missed lesions have therefore been developed to improve detection. The distal attachments and devices for improving the endoscopic view angle are intended to help avoid missing blind spots such as folds and flexures in the colon, whereas the imaging techniques represented by image‐enhanced endoscopy contribute to improving lesion visibility. Recent advances in artificial intelligence‐supported detection systems are expected to supplement an endoscopist's eye through the instant diagnosis of the lesions displayed on the monitor. In this review, we provide an outline of each tool and assess its impact on the reduction in the incidence of missed colorectal polyps by summarizing previous clinical research and meta‐analyses. Although useful, the many devices, image‐enhanced endoscopy, and artificial intelligence tools exhibited various limitations. Integrating these tools can improve their shortcomings. Combining artificial intelligence‐based diagnoses with wide‐angle image‐enhanced endoscopy may be particularly useful. Thus, we hope that such tools will be available in the near future.

The purpose of this research is to determine the organizational fit and organizational myopia levels of employees, to examine whether there is a significant relationship between these levels, to examine how organizational fit affects organizational myopia if there is a significant relationship, and to determine whether organizational myopia differs significantly from demographic factors. In line with this purpose, data has been obtained from medium-sized business employees operating in the private sector by applying a survey method. These data has been analyzed with reliability analysis, factor analysis, normality analysis, correlation, regression, Independent Sample T Test and One-Way ANOVA Test. As a result of the analysis; a positive and highly significant relationship has been found between organizational fit and organizational myopia, and the factor that increased organizational myopia most has been found to be person-organization fit. It has been determined that organizational myopia does not show a significant difference according to demographic factors. [ABSTRACT FROM AUTHOR]

This study aims to investigate the contributing factors affecting the occurrence of crashes while lane-changing maneuvers of drivers. Two different data sets were used from the same drivers' population. The first data set was collected from the traffic police crash reports and the second data set was collected through a questionnaire survey that was conducted among 429 drivers. Two different logistic regression models were developed by employing the two sets of the collected data. The results of the crash occurrence model showed that the drivers' factors (gender, nationality and years of experience in driving), location and surrounding condition factors (non-junction locations, light and road surface conditions) and roads feature (road type, number of lanes and speed limit value) are the significant variables that affected the occurrence of lane-change crashes. About 57.2% of the survey responders committed that different sources of distractions were the main reason for their sudden or unsafe lane change including 21.2% was due to mobile usage. The drivers' behavior model results showed that drivers who did sudden lane change are more likely to be involved in traffic crashes with 2.53 times than others. The drivers who look towards the side mirrors and who look out the windows before lane-change intention have less probability to be involved in crashes by 4.61 and 3.85 times than others, respectively. Another interesting finding is that drivers who reported that they received enough training about safe lane change maneuvering during issuing the driving licenses are less likely to be involved in crashes by 2.06 times than other drivers.

The introduction presents the key concerns and arguments of Critical Perspectives on Teju Cole. Introducing the essays of this volume, it offers insight into Cole's genre-crossing oeuvre and its critical study. It also broadens the outlook of this project by pointing to areas for further research. [ABSTRACT FROM AUTHOR]

From collaborative experiments on Twitter to creative projects in word and image, Teju Cole's work is characterised by connectivity and plasticity. Within the tradition of the public intellectual, it comes into focus as a mode of artistic activism, because it creates new publics through the use of social media and affords new insights in its protean erudition. Cole's distinctive positionality as a public intellectual is theorised as an amalgam of Achille Mbembe's Afropolitanism and Bruce Robbins' cosmopolitanism. Characterised by "distant belongings," this Afrocosmopolitanism informs Cole's Tweets and contributions to other social media. It also infuses the essays in Known and Strange Things and the photographs and texts in Blind Spot and Human Archipelago with thoughtful reflection on and incisive questioning of the most pressing issues of our time. Cole's aesthetic praxis is thus integral to his political stance as a public intellectual. [ABSTRACT FROM AUTHOR]

A significant trend within journalism is the growth of the commentary genre. Another trend is the regional withdrawal within news journalism. News media are closing down district offices, which raises concerns over media shadows and blind spots in coverage. This article addresses both of these trends through a case analysis of the Norwegian newspaper Nordlys. Launching its commentary innovation Nordnorsk debatt, Nordlys aims to exceed its geographical area within these columns, facilitating a regional public sphere in the Arctic region. The article discusses the role of opinion-based journalism in the regional public sphere, within the theoretical perspective of media ecology and institutional theory. We argue that covering the regional level in society is a vital part of journalism’s institutional role. In addition, from an ecological perspective, the role of being a regional voice is important in the national public sphere.

The pupil can be used as an objective measure for testing sensitivities across the visual field (pupil perimetry; PP). The recently developed gaze-contingent flicker PP (gcFPP) is a promising novel form of PP, with improved sensitivity due to retinotopically stable and repeated flickering stimulations, in a short time span. As a diagnostic tool gcFPP has not yet been benchmarked in healthy individuals. The main aims of the current study were to investigate whether gcFPP has the sensitivity to detect the blind spot, and upper versus lower visual field differences that were found before in previous studies. An additional aim was to test for the effects of attentional requirements and background luminance. A total of thirty individuals were tested with gcFPP across two separate experiments. The results showed that pupil oscillation amplitudes were smaller for stimuli presented inside as compared to outside the blind spot. Amplitudes also decreased as a function of eccentricity (i.e., distance to fixation) and were larger for upper as compared to lower visual fields. We measured the strongest and most sensitive pupil responses to stimuli presented on dark- and mid-gray backgrounds, and when observers covertly focused their attention to the flickering stimulus. GcFPP thus evokes pupil responses that are sensitive enough to detect local, and global differences in pupil sensitivity. The findings further encourage (1) the use of a gray background to prevent straylight without affecting gcFPPs sensitivity and (2) the use of an attention task to enhance pupil sensitivity.

Risk associated with vehicle blind spot is a critical concern for road traffic safety that poses a serious threat to drivers as well as vulnerable road users. While driving on the road, it is necessary for drivers to check their mirrors before attempting lane changing, overtaking, turning, or any kind of manoeuvring pattern. But still, there remains some areas around the vehicle that are not visible to driver's peripheral vision even through checking mirrors, known as vehicle blind spots. In this systematic literature, an overview of the blind spot of vehicles along with the associated risks are explained thoroughly by emphasising its importance by focusing on safety aspects. The considered factors included size and visibility of blind spot, demographic factors that influence drivers' awareness and behaviour in blind spot; vehicle characteristics associated with design of different components, and also the efficacy of mirrors in enhancing visibility of blind spots. A quick and concise summary of the literature is highlighted in the current review, and finally, some future directions are proposed to not only help the researchers for a better understanding of blind spot-related driver behavioural issues but also benefit the automotive industry and policymakers to make roads safer.

In his critique of Theory U, Kühl suggests that this approach resembles a management fashion based on four specific characteristics and claims, namely: (1) The simultaneous transformation of nearly everything, (2) The suspension of the differences between science, economics, politics, and religion, (3) Resolving conflicts of interest according to a community ideology, and (4) Reliance on purposive-rational thinking. The first part of this response to Kühl's critique argues that these four claims are unfounded or misguided and outlines why that is the case. The second part explores the questions not raised by Kühl. Finally, the third part of this response explores the blind spots of the framework that underlies Kühl's critique (Luhmann-inspired autopoietic social systems theory) and ways in which Theory U actually addresses these. Reflecting on the origins of Luhmann's approach in the early work of Humberto Maturana and Francisco Varela [1987. The tree of knowledge: The biological roots of human understanding. Shambhala Publications, Inc.], the question is asked what an alternative approach to social systems theory might look like if it were instead grounded in the more evolved and later work of both Maturana and Varela – which in fact turns out to be the case for Theory U.

The temporal monocular crescent (TMC) is the most peripheral portion of the visual field whose perception relies solely on input from the ipsilateral eye. According to a handful of post-mortem histological studies in humans and non-human primates, the TMC is represented visuotopically within the most anterior portion of the primary visual cortical area (V1). However, functional evidence of the TMC visuotopic representation in human visual cortex is rare, mostly due to the small size of the TMC representation (~6% of V1) and due to the technical challenges of stimulating the most peripheral portion of the visual field inside the MRI scanner. In this study, by taking advantage of custom-built MRI-compatible visual stimulation goggles with curved displays, we successfully stimulated the TMC region of the visual field in eight human subjects, half of them right-eye dominant, inside a 3 ​T MRI scanner. This enabled us to localize the representation of TMC, along with the blind spot representation (another visuotopic landmark in V1), in all volunteers, which match the expected spatial pattern based on prior anatomical studies. In all hemispheres, the TMC visuotopic representation was localized along the peripheral border of V1, within the most anterior portion of the calcarine sulcus, without any apparent extension into the second visual area (V2). We further demonstrate the reliability of this localization within/across experimental sessions, and consistency in the spatial location of TMC across individuals after accounting for inter-subject structural differences.

Autonomous driving is evolving through the convergence of object recognition using multiple sensors in the fourth industrial revolution. In this paper, we propose a system that utilizes data logging to control the functions of micro e-mobility vehicles (MEVs) and to build a database for autonomous driving with a gesture recognition algorithm for use in an IoT environment. The proposed system uses multiple sensors installed in an MEV to log driving data as the vehicle operates and to recognize objects surrounding the MEV to remove blind spots. In addition, the proposed system is capable of multi-sensor control and data logging for the MEV based on a gesture recognition algorithm, and it can provide safety information to allow the system to address blind spots or unexpected situations by recognizing the appearances or gestures of pedestrians around the MEV. The proposed system can be applied and extended in various fields, such as 5G communication, autonomous driving, and AI, which are the core technologies of the fourth industrial revolution.

• Technical standards do not consider the implications of on-ramp terminals located along curves. • Effects of radius, ramp-terminal connection type, terminal length, and traffic volume were investigated. • Speed of entering vehicles is mainly influenced by motorway radius and connection type. • Ramp-terminal connection has an impact on longitudinal and transversal driver behaviour. • Unlike linear ones, longer curved terminals may counteract the problems associated with the blind angle. Problem statement . To promote safe and comfortable driving operations, design manuals and policies call for merging terminal ramps to be built along straight roadway sections. However, this prescription may need to be overlooked when there is no alternative to terminals being designed along curves. This study aims to assess the impact of design factors on driver behaviour along curved acceleration terminals with continue or reverse curvature prior to joining the motorway. Methodology. A driving simulation experiment was conducted to observe longitudinal and transversal driver behaviour when certain factors (i.e., radius, ramp length, motorway curve direction, and traffic conditions along the motorway segment) were manipulated. The forty-eight drivers involved were separated into groups based on age and gender. Results. The motorway radius has a significant impact on longitudinal performance, while traffic volume impacts on the merging point where vehicles enter the adjoining motorway lane. Compared to linear terminals, the merging abscissa need to be longer on curved ones so as to compensate for the blind spot and enable drivers to identify and accept gaps between vehicles in the traffic flow. The ramp-terminal connection type influences the speed at the beginning of the terminal, the position of the merging point and transversal driver behaviour. Conclusions. Although some limitations in the study were necessary to limit their impact on the experimental design, the results here may prove useful when considering the adoption of appropriate engineering countermeasures at the design stage of entry terminals along curved motorway segments.

This is a text-experiment of thinking simultaneously intentional implication and transitive intentionality, with a focus on the affective side of perceptions harmonized in subjectivity. Kinesthetic activity is a permanent immanent transcendence. The technique thrown outside is the 'blind spot', the 'point of the gaze' behind the 'point of view'. The exteriority of technique is not objective, we touch or see it when we touch or see the image: we see the invisible and touch the untouchable on the surface - this is the contact with the impossible possibility of the image. In technique, recognition and conceding by anonymous others is an inseparable part of our own kinesthetic organization: a permanent, intrinsic transition within ourselves as something other than ourselves. Our horizons of expectations do not remain unaffected by indexical analogies, by the 'pinning' of a related to habitually assimilated context 'blind spot' in the midst of 'doing-work-as-if'. The affective tissue that accompanies the indexical analogy in mimesis, inscribes into the 'scene' of space the 'scene' of its own habitualized space, and thus a change of optics and perspective becomes possible, decentering becomes possible. This decentering makes the image fluctuating by analogy - "indexical analogies of experience" - with the indexical history. [ABSTRACT FROM AUTHOR]

The aim of this study is to identify the blind points that may arise in intrapreneurship and to propose solutions for these blind points. The study was conducted in October 2019 with 98 whitecollar workers randomly selected from 86 enterprises registered in Adana Chamber of Commerce. The qualitative research method was adopted and a phenomenological research method was used in the research. According to the results, the blind spots of intrapreneurship were determined regarding the dimensions of new initiatives and new businesses, competitive aggression, proactivity, self-renewal risk dimensions. Research results demonstrated that intrapreneurship was the leading factor in the development of entrepreneurship within the organization. The creation and development of new initiatives and businesses can be made possible by eliminating blind spots caused by leaders and employees taking risks, government incentives and supports, education, tax burdens, deficiencies in leader incentives, and problems with information sharing. Economic conditions in the enterprise's intrapreneurial behavior, the problem of adaptation to changing conditions, and insecurity pose significant obstacles in terms of risktaking, besides, these factors were determined as blind spots in intrapreneurship.

The aim of the study is to determine the blind spots of women's entrepreneurship. This study was conducted with 46 women entrepreneurs registered to Adana Chamber of Industry in Turkey in September 2019. A phenomenological research method was adopted in this research. The coding process (conceptualization, classification, component analysis) proposed by Miles and Huberman (1994) was used respectively in data analysis. Findings revealed that the blind spot in entrepreneurship is the dead spot in entrepreneurship according to the field of view of the entrepreneur, which can be prevented with a different perspective and proactive behaviors, which prevents the predicting of unexpected results. A second eye is required to identify the blind spots. In addition, teamwork, transparent management, outsourcing, increasing employee-leader interaction, and referring to external stakeholder opinions can make the blind spot visible. Arrogance and unflexible personality traits, transform the desire of self-realization into an irrepressible ambition, excessive self-confidence are other factors that cause the blind spot. A second eye (consultant, coach, CEO, etc.) is needed to reduce the negative impact of the blind spot on entrepreneurship success. In addition, referring to the ideas of the stakeholders, suppliers, customers, consumers, employees about the success and path of entrepreneurship, teamwork, transparent management, are crucial issues for determining the blind spots.
