Understanding the cognitive aspects of human error will increase the usability of user interfaces.

Understanding the cognitive aspects of human error will increase the usability of user interfaces. It is important to study the cognitive aspects of human error because many disasters have been attributed to operator errors. Creating usable interfaces that reduce the likelihood of error will save industries a great deal of money and may even save human lives. A greater understanding of human errors can be obtained by examining the psychological basis of errors, the methods used to study errors, some of the problems associated with studying errors and different types of errors. Next, the current research findings can then be applied to user interfaces to reduce the probability of user errors. Then, a web survey system, phpESP, will be analyzed based on the guidelines for reducing human error in user interfaces. The analysis of the survey system can server as a guide to help designers reduce potential user errors

Assessing readiness for implementation of prognostics and health management in small and medium enterprises

Prognostics and Health Management (PHM) refers to using robust sensing, monitoring, and control to detect, assess, and track system health degradation and failure modes, allowing for enhanced management and operational decisions. The need for PHM within a manufacturing facility has increased due to a variety of reasons, such as the increasing complexity of manufacturing equipment. A lack of readiness for digital implementations is linked to failure. The literature highlights certain barriers and enablers that can signal whether a technology implementation will be successful, such as management and maintenance employees’ desire to change the existing process, an understanding and willingness to take risks with technology, and having employees with the right competencies and motivations. This thesis identifies barriers and enablers related a successful PHM implementation and develops an assessment tool to identify a company’s readiness level as well as recommendations for increasing the probability of success

De-centering transitions : Low-carbon innovation from the peripheries

Altres ajuts: Acord transformatiu CRUE-CSICUnidad de excelencia María de Maeztu CEX2019-000940-MSocio-technical transitions have garnered significant attention in recent years. Both in theory and practice, however, concerns have been raised about the elitist character of low-carbon transitions. Such dynamics are predominantly imagined through core-periphery relationships. More recently, calls to 'decentre' transitions draw attention to the social and spatial dynamics of transitions in the peripheries. recognizing and fostering transitions from the peripheries offers important opportunities for progressing low-carbon innovation in practice and opens the door to deeper structural transformations. This perspective must nevertheless acknowledge the risk of transitions creating new core-periphery dependencies and reinforcing the strength of elites

Climate justice and global cities: Mapping the emerging discourses

Ever since climate change came to be a matter of political concern, questions of justice have been at the forefront of academic and policy debates in the international arena. Curiously, as attention has shifted to other sites and scales of climate change politics matters of justice have tended to be neglected. In this paper, we examine how discourses of justice are emerging within urban responses to climate change. Drawing on a database of initiatives taking place in 100 global cities and qualitative case-study research in Philadelphia, Quito and Toronto, we examine how notions of distributive and procedural justice are articulated in climate change projects and plans in relation to both adaptation and mitigation. We find that there is limited explicit concern with justice at the urban level. However, where discourses of justice are evident there are important differences emerging between urban responses to adaptation and mitigation, and between those in the north and in the south. Adaptation responses tend to stress the distribution of ‘rights’ to protection, although those in the South also stress the importance of procedural justice. Mitigation responses also stress ‘rights’ to the benefits of responding to climate change, with limited concern for ‘responsibilities’ or for procedural justice. Intriguingly, while adaptation responses tend to stress the rights of individuals, we also find discourses of collective rights emerging in relation to mitigation

A Benefit-Cost Analysis of Tulsa Pre-K, Based on Effects on High School Graduation and College Attendance

This paper presents new benefit-cost estimates for the Tulsa universal preschool program. These calculations are based on estimated effects from previous papers of Tulsa pre-K on high school graduation rates and college attendance rates of students who were enrolled in kindergarten in Tulsa Public Schools in the fall of 2006. In this paper, educational effects from these prior papers are used to infer lifetime earnings effects and are compared with program costs. Our conservative estimates of earnings effects suggest that per pre-K participant, the present value of earnings effects in 2021 dollars is $25,533, compared with program costs of$9,628, for a benefit-cost ratio of 2.65. Compared to prior benefit-cost studies of Tulsa pre-K, this benefit-cost ratio is below what was predicted from Tulsa pre-K’s estimated effects on kindergarten test scores, but above what was predicted from Tulsa pre-K’s estimated effects on grade retention by ninth grade. This fading and recovery of predicted pre-K effects as children go through K–12 and then enter adulthood is consistent with prior research. It attests to the importance of the “soft skill” effects of pre-K and reminds us that short-term studies of pre-K provide useful information for public-policy decisions

SURGICAL SITE INFECTIONS OF PATIENTS FOLLOWING AN ABDOMINAL HYSTERECTOMY: A LITERATURE REVIEW

Surgical site infections (SSIs) are the most common complication resulting from surgical procedures. As they impact patient recovery, well-being, and the health care system, SSIs cost time and money. Researchers have identified a number of factors influencing the causation and prevention of SSIs. The purpose of this paper is to examine the literature in regard to factors that have an impact on the incidence of SSI. A review of the literature was guided by the following PICO question: "In women undergoing abdominal hysterectomy, what are the most effective interventions to be used in a standardized care plan, when compared to current practice with varied and undefined interventions, in reduction of surgical site infection?". Four key variables were identified that either influence the incidence of SSI, or are important in shaping policy concerns regarding SSI. The most evident interventions were prophylactic antibiotics and preoperative washing. The findings from literature regarding dressings remain inconclusive in the reduction of SSI incidence. Furthermore, the findings for obese women showing a higher risk for SSI remain inconclusive, but specialized interventions can be used for this group. These findings help to bring further attention to how research in these key areas can improve future nursing practice

Gate control of sensory neurotransmission in peripheral ganglia by proprioceptive sensory neurons

Melzak and Wall's gate control theory proposed that innocuous input into the dorsal horn of the spinal cord represses pain-inducing nociceptive input. Here we show that input from proprioceptive parvalbumin-expressing sensory neurons tonically represses nociceptor activation within dorsal root ganglia. Deletion of parvalbumin-positive sensory neurons leads to enhanced nociceptor activity measured with GCaMP3, increased input into wide dynamic range neurons of the spinal cord and increased acute and spontaneous pain behaviour, as well as potentiated innocuous sensation. Parvalbumin-positive sensory neurons express the enzymes and transporters necessary to produce vesicular GABA that is known to be released from depolarized somata. These observations support the view that gate control mechanisms occur peripherally within dorsal root ganglia
