This research was focused on increasing the efficiency of aircraft ground handling at the airport. The main goal of the research was to improve the individual processes that are part of the aircraft ground handling in order to speed up this operation, as well as improve the turnaround time between individual flights to enhance the overall throughput of airport stands. The objective of the research was to measure the times of standard airport processes that are part of the aircraft handling, measure the turnaround time between individual flights at the selected airport and increase the efficiency of each process that was measured. After the measurements had been taken, changes were introduced, and the times were measured again. The changes were mainly focused on the following aspects: the position of ground handling equipment before the arrival of the aircraft, the deployment of staff, and the routes taken by ground handling equipment. The measurements were taken during the summer on a fixed stand, with a standard number of employees and with the same type of aircraft. In total, 78 measurements were taken in which 2340 partial times were measured during the entire course of aircraft ground handling before departure to the next destination. After the changes were implemented, the same measurements were taken again to see if the changes that had been implemented could speed up the overall process of the aircraft ground handling. Subsequently, all data were evaluated using statistical methods. All measurements were done at the Košice airport.

Background Turnaround time can be defined as the time from receipt of a sample by the laboratory to the validation of the result. The Royal College of Pathologists recommends that a number of performance indicators for turnaround time should be agreed with stakeholders. The difficulty is in arriving at a goal which has some evidence base to support it other than what may simply be currently achievable technically. This survey sought to establish a professional consensus on the goals and meaning of targets for laboratory turnaround time. Methods A questionnaire was circulated by the National Audit Committee to 173 lead consultants for biochemistry in the UK. The survey asked each participant to state their current target turnaround time for core investigations in a broad group of clinical settings. Each participant was also asked to provide a professional opinion on what turnaround time would pose an unacceptable risk to patient safety for each departmental category. A super majority (2/3) was selected as the threshold for consensus. Results The overall response rate was 58% ( n = 100) with a range of 49–72% across the individual Association for Clinical Biochemistry and Laboratory Medicine regions. The consensus optimal turnaround time for the emergency department was <1 h with >2 h considered unacceptable. The times for general practice and outpatient department were <24 h and >48 h and for Wards <4 h and >12 h, respectively. Conclusions We consider that the figures provide a useful benchmark of current opinion, but clearly more empirical standards will have to develop alongside other aspects of healthcare delivery.

Buildings are rated in five main categories according to the LEED standard to receive an environment-friendly design certificate. Sustainability, water efficiency, material properties, energy consumption, and the quality of indoor spaces are main criteria which confirm the proper function of a building in terms of optimal energy consumption. However, the role of residents and behavioral aspects in the consumption of energy and the decent application of energy standards are neglected. It is beyond doubt that the residents’ behavior is one of the most important factors in performance-based building design. Moreover, the individual mistakes, which most of the times cause energy dissipation, cannot be ignored. This research proposes "Integrated Interactive System" as a human-centered approach with the aim of minimizing energy consumption. A survey is conducted, and this system is evaluated as a case study in Tehran.

This paper presents the procedures developed and used in the individual treatment programs for a group of preschool, postrubella, hearing-impaired children. A case study illustrates the systematic fashion in which the clinician plans programs for each child on the basis of the child’s progress at any given time during the program. The clinician’s decisions are discussed relevant to (1) the choice of a mode(s) for the child and the teacher, (2) the basis for selecting specific target behaviors, (3) the progress of each program, and (4) the implications for future programming.

John Rae, a Scottish antiquarian collector and spirit merchant, played a highly prominent role in the local natural history societies and exhibitions of nineteenth-century Aberdeen. While he modestly described his collection of archaeological lithics and other artefacts, principally drawn from Aberdeenshire but including some items from as far afield as the United States, as a mere ‘routh o’ auld nick-nackets' (abundance of old knick-knacks), a contemporary singled it out as ‘the best known in private hands' (Daily Free Press 4/5/91). After Rae's death, Glasgow Museums, National Museums Scotland, the University of Aberdeen Museum and the Pitt Rivers Museum in Oxford, as well as numerous individual private collectors, purchased items from the collection. Making use of historical and archive materials to explore the individual biography of Rae and his collection, this article examines how Rae's collecting and other antiquarian activities represent and mirror wider developments in both the ‘amateur’ antiquarianism carried out by Rae and his fellow collectors for reasons of self-improvement and moral education, and the ‘professional’ antiquarianism of the museums which purchased his artefacts. Considered in its wider nineteenth-century context, this is a representative case study of the early development of archaeology in the wider intellectual, scientific and social context of the era.

This paper demonstrates how a range of linguistic methods can be harnessed in pursuit of a deeper understanding of the ‘lived experience’ of psychological disorders. It argues that such methods should be applied more in medical contexts, especially in medical humanities. Key extracts from The Unabridged Journals of Sylvia Plath are examined, as a case study of the experience of depression. Combinations of qualitative and quantitative linguistic methods, and inter- and intra-textual comparisons are used to consider distinctive patterns in the use of metaphor, personal pronouns and (the semantics of) verbs, as well as other relevant aspects of language. Qualitative techniques provide in-depth insights, while quantitative corpus methods make the analyses more robust and ensure the breadth necessary to gain insights into the individual experience. Depression emerges as a highly complex and sometimes potentially contradictory experience for Plath, involving both a sense of apathy and inner turmoil. It involves a sense of a split self, trapped in a state that one cannot overcome, and intense self-focus, a turning in on oneself and a view of the world that is both more negative and more polarized than the norm. It is argued that a linguistic approach is useful beyond this specific case.

In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes. Using the partial proportional odds model, the paper investigates determinants of personal disaster preparedness measured as the number of preparedness actions taken. Controlling for village effects, we find that formal education, measured at the individual, household, and community levels, has a positive relationship with taking preparedness measures. For the survey group without past disaster experience, the education level of household members is positively related to disaster preparedness. The findings also show that disaster related training is most effective for individuals with high educational attainment. Furthermore, living in a community with a higher proportion of women who have at least a secondary education increases the likelihood of disaster preparedness. In conclusion, we found that formal education can increase disaster preparedness and reduce vulnerability to natural hazards.

This study is designed to assess the macroeconomic performance of fund-supported programs, and the sequencing and ordering of macroeconomic policies in the context of the Pakistan economy. The generalized evaluation estimator technique has been used to assess the macroeconomic impacts of the IMF supported programs. GDP growth, inflation rate, current account balance, fiscal balance and unemployment are used as the target variables in order to gauge economic performance during the program years. The vector of policy variables (that might have been adopted in the absence of programs) and the vector of foreign exogenous variables are also taken as explanatory variables in the model, so that the individual effect of the IMF supported programs could be assessed. The result suggests that as the IMF prescriptions were applied, the current account balance has worsened, the unemployment rate has significantly increased, and the inflation rate has increased during the years of fund-supported programs. Only the budget balance has shown signs of improvement. Furthermore an inadequate sequencing of reforms has contributed to the further worsening of the economic scenario during the program period.
