Developing and using tasks for the assessment of speaking
2019
This article provides an overview of the development and use of tasks for the assessment of speaking. It first addresses the key role of the assessment of the skill of speaking within language assessment in general and in the context of teaching and learning foreign languages. Then, it discusses how social changes and research have reshaped the way speaking is defined and operationalized, and focuses on how speaking can be assessed more validly and reliably today. The central role of tasks is also discussed, together with the importance of taking into consideration the implications and impact of different task characteristics. Some recommendations for the development of useful and meaningfu…
Project Selection by Constrained Fuzzy AHP
2004
The selection of a project among a set of possible alternatives is a difficult task decision makers have to face. Difficulties in selecting a project arise because of the different goals involved and because of the large number of attributes to consider. Our approach is based upon a fuzzy extension of the Analytic Hierarchy Process (AHP). This paper focuses on the constraints that have to be considered within fuzzy AHP in order to take in account all the available information. This study demonstrates that by considering all the information deriving from the constraints better results in terms of certainty and reliability can be achieved.
Linguistic Approach to Support Human Reliability Analysis and Validation Work in Advanced Radiotherapy Technologies
2019
An integrated methodology, that combines Hierarchical Task Analysis (HTA), Cognitive Task Analysis (CTA) and a modified Human Error Assessment and Reduction Technique (HEART), is proposed to identify safety-relevant human actions in innovative and advanced facilities. It is suggested to use in HEART the concept of linguistic expressions for proportion assessment factors. To prove its applicability, a case study is presented. The validation work has related to safety analyses of accidental events that can involve radiological over-exposure of patients during proton therapy treatments carried out by CATANA (Centro di AdroTerapia Applicazioni Nucleari Avanzate) centre, Italy. CATANA is the fir…
Focusing in Depth: Post-Task Accommodation Shifts After Sustained Near Work with Volumetric Multi-Planar Display
2018
Post-task refraction shifts were evaluated with eccentric photorefraction technique to better understand response of visual system and eye accommodation to sustained near work with 3D image formed by volumetric display.
Retrieving Quantum Information with Active Learning
2019
Active learning is a machine learning method aiming at optimal design for model training. At variance with supervised learning, which labels all samples, active learning provides an improved model by labeling samples with maximal uncertainty according to the estimation model. Here, we propose the use of active learning for efficient quantum information retrieval, which is a crucial task in the design of quantum experiments. Meanwhile, when dealing with large data output, we employ active learning for the sake of classification with minimal cost in fidelity loss. Indeed, labeling only 5% samples, we achieve almost 90% rate estimation. The introduction of active learning methods in the data a…
Three-Way Interactions Among Interruptions/Multitasking Demands, Occupational Age, and Alertness: A Diary Study
2015
In this study, we examined the within-person relationships between workday “cognitive” stressors (multitasking demands and workflow interruptions) and strain (situational well-being throughout the day and irritation in the evening). We hypothesized that occupational age, in terms of job tenure and an indicator of functional age (alertness), would moderate these relationships in that employees with low experience and low alertness would suffer most from the stressors. We conducted a 5-day diary study in a sample of 123 nurses, with 4 measurements per day (3 taken during the work shift and 1 taken in the evening), and 1 survey (occupational age) and computer-based cognitive performance test b…
Coping with Burnout Symptoms through Task Significance in Professionals Working with Individuals with Intellectual Disability
2021
ABSTRACT This study examined an intervention that links task significance (one’s job has a positive impact on other people) to burnout symptoms of professionals working in organizations for individuals with intellectual disability. Professionals assigned to the experimental condition participated in teams designed to enhance the positive impact of their work on others (task significance). To do so, teams focused on a task to improve the quality of life of individuals with intellectual disability. Professionals assigned to the control condition did not participate in these teams, and they continued with their usual work. All the participating professionals answered a questionnaire abou…
Unusual business or business as usual: An investigation of meeting support requirements in multilateral diplomacy
1993
Abstract The concept of supporting meetings at the same time and at the same place with computers raises the problem of how salient features of group behaviors are understood in meetings. In this paper we critically examine some aspects of meeting behaviors. We point out that the idea of small, cohesive business teams is not necessarily a valid starting point in thinking of all meeting support. In particular, beliefs that relate to user aspects, group features such as composition, structure and protocols, and task characteristics such as nature, importance, and goals in meetings may need deliberation in many group decision support systems (GDSS) interventions. To demonstrate the credibility…
Investigating the impacts of team type and design on virtual team processes
2017
While much is known about virtual team processes and outcomes, the literature relies on a variety of team configurations and types (including student versus organizational samples, short-term versus long-term teams, functional versus project-based teams, and teams with various task types) yet has not systematically examined how these differences impact team processes. This is important because much of the virtual teams research has been based on student samples, which are easier to access and control, with the implicit assumption that the findings from student samples will generalize to organizational virtual teams. This manuscript reviews the last 15 years of research on virtual teams and …
An Emergent Taxonomy of Public Personnel Management: Exploring the Task Environment of Human Resource Managers in Spanish Local Government
2018
This study presents a taxonomy for public personnel management based on emergent profiles of local human resource managers in Spain. The analysis focuses on the task environments of managers defined by three salient constructs from strategic human resources management research. Specifically, this study looks at the level of participation of human resource managers in strategic-level policy-making processes, vertical and horizontal policy integration, and the flexibility of human resource managers in interpreting and implementing key functions of personnel management (i.e., recruitment, hiring, and remuneration). The results yield five distinct profiles that describe different approaches of…
