The Effect of Active and Passive Control on Air Traffic Controller Dynamic Memory

The purpose of this study was to investigate the effect of automated and passive control on air traffic controller dynamic memory. The study consisted of two experiments, each involving a realistic ATC scenario for radar approach control with a mix of arriving and departing traffic. In Experiment I, the subjects performed manual control of the traffic while, in Experiment II, the scenario was highly automated and the subjects were tasked with only monitoring the situation. The dynamic memory performance was measured by interrupting the scenario and having the subjects recall the traffic situation at the moment of simulation interruption. The accuracy of recall was compared between the manual and automated scenarios. It was anticipated that subjects exercising manual control would have superior recall ability and a picture. This would have significant implications on the design of automated systems for ATC and the role of the human controller within the ATC system

Psychophysiological measurements in programming task:guidelines for conducting EMG research

Abstract. Programming languages have been studied and developed throughout history of programming. There are lots of different programming languages that are being used in software development, but only core languages are taught in Universities. Programming languages usually have their own syntax, which may differ greatly from each other. Using different programming languages for same task may provoke different emotions in programmers, depending their knowledge on the language. Research on programming and programming languages have generally focused on technical and exterior aspects. More recently, there has been some research on the programmers and their emotions during the programming tasks. This master’s thesis focuses on latter and aims to provide new information of programmers experienced emotions during the programming tasks by using EMG-recordings. This master thesis’ main study focus is in psychophysiology, which combines psychology to physiological research, by finding correlation between physiological activity and emotional phenomenon. This study assessed university students experienced emotions when conducting programming tasks with C and Python programming languages. EMG measurement device was used on the test participants to record signal data from facial based muscles for smiling and frowning activity, which are linked to positive and negative emotions. This study’s results showed small differences with emotional experiences during the programming tasks, but the overall results were not statistically significant. Therefore, more research on this topic is needed for more consistent results. Additionally, this research has provided guidelines on how EMG studies are conducted on laboratory setting and suggestions for future studies

Human Reliability Analysis in Healthcare

The problem of human error in healthcare is well documented. Other domains (such as transportation and energy) have used techniques and methods from the engineering disciplines to analyze and ultimately reduce instances of error. In New York State (NYS), the Department of Health (DOH) requires the use of one such method, Root Cause Analysis (RCA), in investigating and reporting the occurrence of and response to sentinel events by hospitals. Despite the use of the RCA technique in an attempt to identify and mitigate the root causes of error, the problem of human error contributing to sentinel events persists. Experts in Human Reliability Analysis (HRA) contend that human performance is too complex to be represented by models used in engineering systems reliability. A method to analyze human erroneous actions was created that considers operator context and control based on a model of human cognition. The technique, called the Cognitive Reliability and Error Analysis Method (CREAM), was used to reanalyze 58 sentinel event cases Rochester General Hospital previously analyzed using RCA. Despite serious data limitations, our results reveal an apparent gap between RCA and CREAM analyses. We suggest that the gap highlights incomplete RCA that minimizes or does not appreciate the role that organizational factors play in contributing to the sentinel events. Due to data limitations, we cannot identify specific interventions to mitigate risk for sentinel events. However, we make several recommendations for improving the RCA process at Rochester General Hospital in an effort to improve the validity of the analyses data for further study

Experimental investigation of contamination prevention techniques to cryogenic surfaces on board orbiting spacecraft

Within the simulation limitations of on-orbit conditions, it was demonstrated that a helium purge system could be an effective method for reducing the incoming flux of contaminant species. Although a generalized purge system was employed in conjunction with basic telescope components, the simulation provided data that could be used for further modeling and design of a specific helium injection system. Experimental telescope pressures required for 90% attenuation appeared to be slightly higher (factor of 2 to 5). Cooling the helium purge gas and telescope components from 300 to 140 K had no measurable effect on stopping efficiency of a given mass flow of helium from the diffuse injector

The skill gap and polarization of the software labour force: Early signs of the War of Talents between software professionals and how it threatens wellbeing

The demand for high-skill and deep knowledge is a key characteristic for modern-day software business. In addition, the whole impact of information and communication technology (ICT) is seen as a cross-cutting element in different industries. The software industry in Finland is suffering from a severe labour shortage and the estimations of needed labour are ranging from 7,000 to 15,000 software professional. However, despite all development and research done, the question, whether the software companies are requesting more employers or are they looking for more diverse skills, remains unanswered. Furthermore, previously there has little if any discussion, on whose responsibility is to ensure that future software experts have the right kinds of skills and competencies to secure their successful work career. This study focuses on the skill polarization between software professionals, referred to as the ‘War of Talents’ in this study, by using data collected by a survey (n=90) from Finnish software businesses. The results reveal some indication of ongoing skill polarization in the field and its possible impacts are discussed. Furthermore, the potential threatening impacts of the polarization process on the well-being in the information society are observed and reported. In addition, the paper proposes adding skill development applications among the offering of eWellbeing services due to the importance of work-related competencies to the self-image – and therefore also wellbeing – of individuals.The demand for high-skill and deep knowledge is a key characteristic for modern-day software business.

Effects of alternative soy sources on growth performance in early-weaned pigs

A total of 144 pigs (initial body wt of 10.4 lb) was used in a 56-d growth assay to determine the effects of different soybean preparations on growth performance and cost of gain in nursery pigs. Experimental diets were fed in three phases from d 0 to 35 postweaning (Le., d 0 to 7, 7 to 21, and 21 to 35). Treatments were a soybean meal-based regimen; a dry-extruded whole soybeans (mill-run) regimen; and a specially processed soy products regimen (Le., soy isolate in Phase I, soy concentrate in Phase 11, and extruded soy flour in Phase Ill). All diets were formulated to 1. 55, 1. 25, and 1.15% lysine for Phases I, 11, and III, respectively. Fat additions to the soybean meal and specialty soy product treatments were 2, 2, and 3%, for Phases I, 11, and III, respectively. The diets with extruded soybeans had more total fat (2.5, 3.8, and 4.8% greater percentage ether extract in Phases I, 11, and III, respectively) than the soybean meal-based control. On d 35 postweaning, the pigs were switched to the same soybean meal-based grower diet (.9% lysine) for a period of 3 wk. During Phase I (d 0 to 7 postweaning), pigs fed soybean meal gained 25% less and were 22% less efficient than those fed extruded soybeans and the specially processed soy products. Average daily feed intake was not affected by dietary treatment; however, pigs fed the specially processed soy product had the greatest ADG of any treatment, and numerically, the best efficiencies of gain. No statistical differences were found for ADG, ADFI, or F/G among treatments from d 7 to 21, 21 to 35, or 35 to 56 of the experiment. Thus, overall (from d 0 to 56 postweaning), pigs fed the various soybean protein sources had similar growth performance. However, overall costs per pound of gain were $.33,$.34, and $.42 for pigs fed extruded soybeans, soybean meal, and the specialty soy products, respectively. In conclusion, although the specially processed soy products regimen (Le., soy isolate) supported the greatest growth performance immediately after weaning (d 0 to 7), the best cost of gain was achieved by feeding extruded soybeans. However, the additional fat provided by extruded soybeans did not influence pig performance in this experiment.; Swine Day, Manhattan, KS, November 17, 199

Ethical Governance of eGovernment Ecosystems

Digitisation of governmental services has become a common approach to make governing more effective and efficient. The eGovernment services can be built on top of a variety of information systems and supplied to and between individuals and organisations on both national and international levels. This results in a complex organisational and sociotechnical ecosystem containing a vast amount of variables affecting the privacy and safety of citizens. Thus, achieving these better societies relies strongly on common trust between the citizens and governments. This calls for ‘governance of governance’, which can prove to be difficult to manage. Even in this challenging environment, it is crucial that ethical principles are applied to the highest possible degree. Yet, in current research, the citizens are often neglected. In order to develop a better society for all, we should objectively consider the ends and means of eGovernment. In this paper, we study the relation of the citizens and eGovernment systems from an ethical perspective in order to represent which ethical considerations should be made if one wishes to truly aim for a better society
