EFFECTS OF TELESHOPPING ON THE USE OF TIME AND SPACE

Developments in teleshopping offer many possible uses. As a supplement and alternative to transportation, teleshopping may have effects on traffic and physical planning. The use of time (both by point in time and by time budget) and the use of space (location and infrastructure) will change. These ideas have been elaborated in an investigation into a teleshopping service that examined the effects of teleshopping on the use of time and space. A sample of teleshoppers noted shopping trips during a number of days. With the aid of these diaries and the answers to a number of background questions, insight was obtained into the group, their motives, their shopping behavior, and the changes that occurred in the use of time and space. Teleshopping saved time, but most people did not mention any new activity. There was a change in shopping times. Some shopping trips could be scheduled to avoid the rush hour. Teleshopping also had effects on the use of space. A change in travel behavior occurred. Telecommunication was substituted for some consumer trips, and the modal split of some trips changed.
Organizing for Sustainability

A large literature has been generated about sustainability, and many organizations, governments, communities and citizens have focused on it. Yet, given how quickly the limits of the current models of the global economy are being approached, we must accelerate the rate at which we learn to operate differently. This first volume of the Emerald series Organizing for Sustainable Effectiveness learns from some of the pioneers articulating these challenges and organizing to address them. There is an urgent need to grow the knowledge bases to guide the transition. Each chapter in this volume, crafted to bring together the knowledge of practice and theory, is based on rich empirical data about particular cases in which organizations are, individually or collectively, working to build a more sustainable future. Contributors bring theoretical knowledge to bear on these case examples and test the applicability of the formal knowledge base about management and organizations, while refining, modifying, and extending it to increase its usefulness in addressing the challenges of organizing for sustainable effectiveness.
Arbeiten und Lernen im Wandel: Teil V: Die Codierung der offenen Angaben zur beruflichen Tätigkeit, Ausbildung und Branche

"The IAB-ALWA study (Work and Learning in a Changing World) was conducted between September 2007 and March 2008 on behalf of the IAB. The aim of this representative telephone survey was to collect systematically educational and employment histories of 10,000 adults who were between 18 and 50 years old. The aim of the coding process was to generate codes from the open text answers of questions about occupations, occupational ambition, vocational training and economic sector. First the theoretical basis of the coding process of the open text answer of the occupation with the help of the Dokumentationskennziffer (documentation figure (DKZ) from the Frederal Employment Agency will be outlined. Next the technical implementation is described which can be organized into several steps: an automatic coding, a manual coding and the handling of problematic cases. Afterwards the coding process for vocational training and courses is described. Additionally, the coding process for economic sectors with the help of the German classification WZ08 (Klassifikation der Wirtschaftszweige, Ausgabe 2008) is illustrated. Finally, the coder training and the quality assurance of the coding is explained and a conclusion is drawn.

Features Based on Thin-section Computed Tomography Identify the Typeof lung Adenocarcinoma

Background: To investigate whether thin-section computed tomography (TSCT) features may efficiently guide the invasiveness basedclassification of lung adenocarcinoma. Methods: Totally, 316 lung adenocarcinoma patients (from 2011-2015) were divided into three groups: 56 adenocarcinoma in situ (AIS), 98 minimally invasive adenocarcinoma (MIA), and 162 invasive adenocarcinoma (IAC) according their pathological results. Their TSCT features, including nodule pattern, shape, pleural invasion, solid proportion, border, margin, vascular convergence, air bronchograms, vacuole sign, pleural indentation, diameter, solid diameter, and CT values of ground-glass nodules (GGN) were analyzed. Pearson’s chi-square test, Fisher’s exact test and One-way ANOVA were adopted tocomparebetweengroups. Receiver operating characteristic (ROC) analysis wereperformedto assess its value for prediction and diagnosis. Results: Patients with IAC were significantly elder than those in AIS or MIA group,and more MIA patients had a smoking history than AIS and IAC. No recurrence happened in the AIS and MIA groups, while 4.3% recurrences were confirmed in the IAC group. As for TSCT variables, we found AIS group showed dominantly higher 91.07%PGGN pattern and 87.50% round/oval nodules than that in MIA and IAC group. In contrast, MIA group showed more cases with undefined border and vascular convergence than AIS and IAC group. Importantly, IAC group uniquely showed higher frequency of pleural invasion compared with MIA and AIS group. The majority of patients (82.1%) in IAC group showed ≥ 50% solid proportion. We found diameter and solid diameter of the lesions were notably larger in the IAC group compared with AIS and MIA groupin quantitative aspect. In addition, for MGGNs, the CT values of ground-glass opacity (GGO) and ground-glass opacity solid portion (GGO-solid) were both higher in the IAC group than AIS and MIA. Finally, we also observed that smooth margin took a dominant proportion in the AIS group while most cases in the IAC group had a lobulate margin. Patients in MIA and IAC group shared higher level of air bronchograms and vacuole signs than AIS group. Conclusions: The unique features in different groups identified by TSCT had diagnosis value for lung adenocarcinoma.
THE WAGENINGEN B-SCREW SERIES

The Wageningen B-screw series have been extended gradually to 21 screw series having blade numbers ranging from 2 to 7 and blade-area ratios between 0.30 and 1.05. Recently, the existing screw series were correlated with the new screw series with an up-to-date fairing technique. This correlation was made by means of a regression analysis. Further, the influence of the Reynolds number ( scale effect ) on the test results was taken into account. For ship maneuvering studies, it is necessary to know the propeller thrust and torque characteristics over a wider range of operating conditions. Therefore, open-water tests with B-series screws over the entire region of operation were carried out. In order to obtain systematic knowledge on the cavitation characteristics of the B-screw series in a uniform flow, tests have been conducted. The curves for cavitation inception were established and the influence of cavitation on propeller thrust and torque was determined.
Symptom profiles in patients with Alzheimer’s disease with and without concomitant cerebrovascular disease: an observational study

Background: Diagnostic criteria of Alzheimer’s disease (AD) and vascular cognitive impairment (VCI) describe different cognitive profiles. AD patients often have concomitant cerebrovascular disease (CVD) and these patients could therefore be expected to display symptoms of both AD and VCI. AD patients with concomitant CVD display symptoms of cognitive impairment with less AD pathology than those without CVD. Medial temporal atrophy (MTA) on magnetic resonance imaging (MRI) is a biomarker of neurodegeneration in AD, and we would expect less MTA in AD patients with CVD. The first aim was to examine whether there were differences in the results of cognitive tests for memory, executive function, and processing speed, or in depressive symptoms, between AD patients with and without CVD. Secondly, to assess whether MTA on MRI is more pronounced among AD patients without CVD. Methods: A total of 192 AD patients with amnestic mild cognitive impairment or mild dementia underwent cognitive assessment and depression screening. Cerebral MRIs were assessed for MTA, white matter hyperintensities, and lacunar and cortical infarcts. CVD was defined as the presence of white matter hyperintensities Fazekas scale ≥2 or any infarct. To study the effect of CVD, several multiple linear regression analyses were carried out using CVD adjusted for age and sex as the independent variable, and cognitive test scores, depression scores, and MTA as dependent variables. Results: Mean age was 72.2 (SD 8.3) years. The number of AD patients with and without concomitant CVD was 121 and 71, respectively. The group with CVD scored significantly lower on tests of attention, executive function and immediate recall compared with the group without CVD. In analyses controlled for age and sex, concomitant CVD was not associated with significant differences in any cognitive test nor in depressive symptoms. A statistically significant association between AD with concomitant CVD and more pronounced MTA was identified. Conclusions: The results indicate that cognitive test profiles, depressive symptoms, and MTA scores cannot be used to distinguish AD patients with and without CVD.
Optimisation of Catalytic Converter Gas Flow Distribution by CFD Prediction

Performance improvements, of catalytic converters, and longer service life can be achieved by improving the flow distribution of exhaust gases. Computational Fluid Dynamics (CFD) is an excellent and relatively inexpensive technique for rapid and efficient optimization of the flow. Studies indicate that a 3D representation is necessary because 2D is insufficient. The computations are confirmed by measurements of steady flow. A number of design parameters are systematically investigated and their effects on an index of flow uniformity established. The parameters include the geometry of the inlet tube and inlet cone, the geometry and placement of the monoliths, and the shape of the exit cone. The difficult flow conditions in close coupled converters are examined. The flow path is improved and the best location of the HEGO-sensor found. (A) For the covering abstract see IRRD 858138.
CORROSION OF BARE CONCENTRIC NEUTRALS IN URD SYSTEMS: A REVIEW

This paper reviews reports that have been written from 1961 to 1974 on the corrosion of the concentric neutrals on buried cable in URD systems. An attempt is made to clarify some misunderstandings such as the growing tendency to catalog the failure of concentric neutrals as ac corrosion, or refer to rectification as the cause of the failures. From this review, it appears that a number of causes exist, working separately or collectively, and that each field situation has its own peculiarities. Several factors which result in concentric neutral corrosion, as identified by the author's own experience, are presented.
Cause of Death and Factors Associated With 5-Year Mortality After Hip Fracture Surgery

Aim: the aims of this study were to identify the 5-year mortality rate after hip fracture, identify factors associated with this mortality, and identify the cause of death in these patients.Materials and Methods: A retrospective cohort study of geriatric patients (≥60 years of age) undergoing a hip fracture surgical procedure admitted to our institution between the 1 January 2012 and 31 December 2016 was performed. Demographic and clinical characteristics were collected. Patients or their careers were contacted by telephone or outpatient to ascertain their vital status, and cause of death if they had died at 5-year post-surgery. According to whether they were alive or death at 5-year post-surgery, patients were divided into survivor or non-survivor group. All variables including demographic data and clinical characteristics were compared for both survivors and non-survivors. Cox proportional hazards were used to determine independent risk factors for 5-year mortality. All cause of 5-year mortality in hip fracture were recorded.Result: A total of 327 patients with a median age of 80.00 years were included. 5-year mortality was 40.1%, and the death peak was concentrated during 6 months after surgery. The final multivariate model included 4 independent mortality risk factors: advanced age, stroke, albumin, delayed surgery, with an HR (95% confidence interval) 1.052(1.025-1.080), 1.612(1.104-2.353), 0.940(0.900-0.982), 1.638(1.072-2.498), respectively. Pulmonary infection, and cardiovascular disease were the most common cause of 5-year death.Conclusion: Our results showed that 5-year mortality was 40.1%. Advanced age, stroke, low albumin, and delayed surgery were associated with 5-year mortality after hip fracture surgery. Pulmonary infection, and cardiovascular disease were the most common cause of death.
Force Optimization and Flow Field Characterization from a Flapping Wing Mechanism

Force Optimization and Flow Field Characterization from a Flapping Wing Mechanism Nathaniel Stephen Naegle Department of Mechanical Engineering Master of Science Flapping flight shows promise for micro air vehicle design because flapping wings provide superior aerodynamic performance than that of fixed wings and rotors at low Reynolds numbers. In these flight regimes, unsteady effects become increasingly important. This thesis explores some of the unsteady effects that provide additional lift to flapping wings through an experiment-based optimization of the kinematics of a flapping wing mechanism in a water tunnel. The mechanism wings and flow environment were scaled to simulate the flight of the hawkmoth (Manduca sexta) at hovering or near-hovering speeds. The optimization was repeated using rigid and flexible wings to evaluate the impact that wing flexibility has on aerodynamic performance of flapping wings. The trajectories that produced the highest lift were compared using particle image velocimetry to characterize the flow features produced during the periods of peak lift. A leading edge vortex was observed with all of the flapping trajectories and both wing types, the strength of which corresponded to the measured amount of lift of the wing. This research furthers our understanding of the lift-generating mechanisms used in nature and can be applied to improve the design of micro air vehicles.
Knowledge workers and their relationships with organisations

The programme of research examines knowledge workers, their relationships with organisations, and perceptions of management practices through the development of a theoretical model and knowledge worker archetypes. Knowledge worker and non-knowledge worker archetypes were established through an analysis of the extant literature. After an exploratory study of knowledge workers in a small software development company the archetypes were refined to include occupational classification data and the findings from Study 1. The Knowledge Worker Characteristics Model (KWCM) was developed as a theoretical framework in order to analyse differences between the two archetypes within the IT sector. The KWCM comprises of the variables within the job characteristics model, creativity, goal orientation, identification and commitment. In Study 2, a global web based survey was conducted. There were insufficient non-knowledge worker responses and therefore a cluster analysis was conducted to interrogate the archetypes further. This demonstrated, unexpectedly, that that there were marked differences within the knowledge worker archetypes suggesting the need to granulate the archetype further. The theoretical framework and the archetypes were revised (as programmers and web developers) and the research study was refocused to examine occupational differences within knowledge work. Findings from Study 2 identified that there were significant differences between the archetypes in relation to the KWCM. 19 semi-structured interviews were conducted in Study 3 in order to deepen the analysis using qualitative data and to examine perceptions of people management practices. The findings from both studies demonstrate that there were significant differences between the two groups but also that job challenge, problem solving, intrinsic reward and team identification were of importance to both groups of knowledge workers. This thesis presents an examination of knowledge workers’ perceptions of work, organisations and people management practices in the granulation and differentiation of occupational archetypes.
Contrasting Scenarios: Embracing Speech Recognition

The purpose of this chapter is to describe the use of caricatured contrasting scenarios (Bodker, 2000) and how they can be used to consider potential designs for disruptive technologies. The disruptive technology in this case is Automatic Speech Recognition (ASR) software in workplace settings. The particular workplace is the Magistrates Court of the Australian Capital Territory. ----- Caricatured contrasting scenarios are ideally suited to exploring how ASR might be implemented in a particular setting because they allow potential implementations to be “sketched” quickly and with little effort. This sketching of potential interactions and the emphasis of both positive and negative outcomes allows the benefits and pitfalls of design decisions to become apparent. ----- A brief description of the Court is given, describing the reasons for choosing the Court for this case study. The work of the Court is framed as taking place in two modes: Front of house, where the courtroom itself is, and backstage, where documents are processed and the business of the court is recorded and encoded into various systems. ----- Caricatured contrasting scenarios describing the introduction of ASR to the front of house are presented and then analysed. These scenarios show that the introduction of ASR to the court would be highly problematic. ----- The final section describes how ASR could be re-imagined in order to make it useful for the court. A final scenario is presented that describes how this re-imagined ASR could be integrated into both the front of house and backstage of the court in a way that could strengthen both processes.
Dynamic Flashing Yellow Arrow (FYA): A Study on Variable Left Turn Mode Operational and Safety Impacts

Accommodating left turns at signalized intersections has been a challenge for traffic engineers as they seek balance between two conflicting goals; capacity and safety. The use of a four-section head for the left-turn lane only with a flashing yellow arrow indication for permissive left turns has been deemed to be the new standard for signalization. With the advent of this new signal configuration, there was the opportunity to take the protected-permitted left-turn mode to a new level of operation. Although numerous studies have developed warrants and guidelines for selecting left-turn control types, to date there are no clear or uniform standards for the implementation of a variable left-turn mode, changing by time-of-day. Hence, there is a need to develop an interactive and efficient framework to serve as a decision support system (DSS) for the evaluation of left-turn phasing alternative based on intersection conditions. This framework will allow (1) an interactive evaluation of left-turn phasing and ultimately recommend phasing mode by time-of-day and (2) Traffic Management Center (TMC) data to be fed into the DSS so that intersections requiring attention/modification of left-turn mode can be flagged. The current study develops an interactive DSS for assessing the likely benefits of warranting a permitted left-turn phase using custom design approach. The developed DSS is designed to predict these benefits based on multilevel factorial parameters that are practical and applicable to assist TMCs in evaluating the efficiency of a permitted left-turn phase by time of day.
The effect of pavement material on road lighting performance

The recommended design method for road lighting in the UK uses data for characterising the reflection properties of road surfaces (BS5489-1:2003) called the representative British road surface (C2), which is modified for concrete roads. A reduced reflection coefficient table, an r-table, is used to give the reflection properties of a road surface. This gives the distribution of two metrics: Q0 (a metric of the diffuse reflection) and S1 (a metric of specular reflection). Research was conducted to investigate the applicability of the C2 design method to new pavement materials including porous asphalt. The effects of using the r-tables for the new and established materials rather than the representative British road surface on the capital cost, energy cost and life cycle cost of the road lighting were considered. It was shown that C2 surfaces overestimated the average road surface luminances produced for both new and established pavement materials. Using r-tables better matched to the reflection properties of pavement materials increased costs. Six actions were recommended.
