Pedestrian Crossing

Although concepts of the continuous flow intersection (CFI) have been around for approximately four decades, minimal or no literature describing studies that have analyzed pedestrian traffic performance at these intersections is available. Several studies have reported on the qualitative and quantitative benefits for the vehicular traffic performance of CFIs in comparison with the benefits for the vehicular traffic performance of conventional intersections but have provided minimal or no discussion about pedestrian traffic performance. As a novel intersection design, many important considerations are required to design pedestrian accesses and crossings at CFIs without compromising pedestrian safety and vehicular traffic performance. In this paper, the design methodologies for providing pedestrian access and related pedestrian signal timings are discussed. Modeling was conducted on three typical geometries for CFIs with base signal timings optimized for vehicular traffic performance. The results indicate an acceptable pedestrian level of service of B or C on the basis of the average delay per stop experienced by any pedestrian for pedestrian crossings at the typical CFI geometries modeled. All pedestrians served at the CFIs are accommodated within two cycles for a typical signal cycle length ranging from 60 to 100 s.

Purpose This paper aims to examine the principles that underpin library assessment, methods used for impact and performance evaluation and how academic libraries should use the findings, and it discusses how value frameworks help. Design/methodology/approach This is a literature review covering aspects of value (value propositions, value co-creation), value frameworks (including the 2015 ACRL framework, Holbrook typology with worked example), data analytics and collaborative projects including LibQUAL+ initiatives and the use of balanced scorecard principles (including a values scorecard). Findings The use of data analytics in library assessment requires collaboration among library services to develop reliable data sets. Scorecards help ongoing impact and performance evaluation. Queries that arise may require a framework, or logic model, to formulate suitable questions and assemble evidence (qualitative and quantitative) to answer new questions about the value of library services. The perceived value framework of Holbrook’s typology, the values scorecard and the ACRL framework all support the deeper level of inquiry required. Research limitations/implications Includes examples of possible application of frameworks. Practical implications A value framework might help data analytic approaches in combining qualitative and quantitative data. Social implications Impact assessment may require assessing how value is co-created with library users in use of e-resources and open data. Originality/value The study contrasts the varying approaches to impact evaluation and library assessment in academic libraries, and it examines more in-depth value frameworks.

The Voice

Specific problems in the professional life of opera singers were examined in an exploratory study with both a qualitative and quantitative approach. Semi-structured interviews involved 15 opera singers who were asked to report problems related to their professional work, coping strategies, motivational factors, and, particularly, strongly emotional singing experiences. Psychological problems were most frequent: the opera singers’ preoccupation with the risk of vocal indisposition, i.e., not being able to sing and worry about others’ opinions about their performance. A specific habit of singers involved testing the voice (vocalizing) regularly to prove its quality and mere existence. Concern with physical problems centered on respiratory tract symptoms that could cause vocal indisposition. Psychosocial problems concerned mostly difficulties in maintaining a family life due to travel and irregular working hours. A questionnaire was designed to collect qualitative data and sent to 36 permanently employed and 36 freelance opera singers. Response rate was 67%. Differences regarding singers’ ages, genders, and occupational situations were examined. Significant positive correlations were found between worry about others’ opinions and a number of variables: somatic problems, testing the voice, depression, and performance anxiety.

And Task

An ecological model of motor behavior presented by Davis and Burton (12) suggests that the qualitative and quantitative aspects of motor behavior for all persons emerge from three sets of constraints: performer, environmental, and task. The involvement and performance of movement activities by children with physical impairments may be optimized by carefully manipulating one or more of these three types of constraints, and by recognizing and accepting that the optimal movement patterns used by these children with unique performer constraints may differ from those exhibited by other children.

Previous studies demonstrate that plants played a significant role in the edible garden plantings. Therefore, this study aims to analyse and evaluate the practicality and performance of plants selected in composing the recycle edible garden at Masjid As-Siddiq. This paper discusses the issues, challenges and imperatives of how a successful plants selection would lead towards survival and sustenance food for the community. The data derived from qualitative and quantitative method through photo and images recorded throughout the implementation period. The results will interpret relevant information about the plants potential in surviving and becoming sustenance towards the sustainable community.

Knowledge management and knowledge assets have gained much prominence in recent years and are said to improve organizational performance. Knowledge capture and acquisition mechanisms enhance organizational memory and performance. However, knowledge capture and acquisition mechanisms in higher education institutions are not well known. The aim of this study was to investigate the knowledge capture and acquisition mechanisms at Kisii University. This was a case study in which data were collected through interviews and questionnaires. Purposive sampling was used to determine interview participants while questionnaire respondents were selected through stratified random sampling. Qualitative and quantitative data were analysed using SPSS® student version 14; it revealed that there were various knowledge capture and acquisition mechanisms at Kisii University. It was also established that the University encountered various challenges in knowledge capture and acquisition and lacked some essential knowledge capture and acquisition mechanisms. In this regard, this study proposed knowledge capture and acquisition guidelines that may be adopted by the University to enhance its organizational memory and performance.
