Abstract
In this chapter, we discuss health-related physical fitness and motor development assessments for students with physical disabilities or other health impairments in special education using traditional and innovative techniques. Traditional assessment techniques are those that are more standardized and formalized, while innovative assessment techniques refer to new variations or ways (alternative/authentic) to assess the abilities of students with physical disabilities and other health impairments. According to the United States Department of Education (2009), students with disabilities must be included in State and local assessments. Even though there has been significant growth in numbers, diversity and academic orientation of persons with physical disabilities, assessments practices have largely remained the same over the years. Adopting innovative pedagogies and emerging innovative assessment techniques may address some unmet needs of current students with disabilities faced with assessment biases.

Abstract
Purpose
The purpose of this paper is to ascertain overall system health and maintenance needs with degree of certainty using condition‐monitoring data with hierarchical fuzzy inference system.
Design/methodology/approach
In process plants, equipment condition is ascertained using condition‐monitoring data for each condition indicator. For large systems with multiple condition indicators, estimating the overall system health becomes cumbersome. The decision of selecting the equipment for an overhaul is mostly determined by generic guidelines, and seldom backed up by condition‐monitoring data. The proposed approach uses a hierarchical system health assessment using fuzzy inference on condition‐monitoring data collected over a period. Each subsystem health is ascertained with degree of certainty using degree of match operation performed on fuzzy sets of condition‐monitoring data and expert opinion. Fuzzy sets and approximate reasoning are used to handle the uncertainty/imprecision in data and subjectivity/vagueness of expert domain knowledge.
Findings
The proposed approach has been applied to a large electric motor (> 500kW), which is treated as four subsystems i.e. power transmission system, electromagnetic system, ventilation system and support system. Fuzzy set of condition‐monitoring data of each condition indicator on each subsystem is used to ascertain the degree of match with the expert opinion fuzzy set, thus inferring the need for periodical overhaul. Subjective expert opinion and quantitative condition‐monitoring data have been evaluated using hierarchical fuzzy inference system with a rule base. It is found that the certainty of each subsystem's health is not the same at the end of 600 days of monitoring and can be classified as “very good”, “good”, “marginal” and “sick”. Degree of certainty has helped in taking a managerial decision to avoid “over‐maintenance” and to ensure reliability. Large volumes of condition‐monitoring data not only helped in assessing motor overhaul health, but also guide the maintenance engineer to suitably review maintenance/monitoring strategy on similar systems to achieve desired reliability goals.
Practical implications
Condition‐monitoring data collected for long periods can be utilized to understand the degree of certainty of degradation pattern in the longer time frame with reference to domain knowledge to improve effectiveness of predictive maintenance towards reliability.
Originality/value
The paper gives an opportunity to evaluate quantitative condition‐monitoring data and subjective/qualitative domain expertise using fuzzy sets. The predictive maintenance cycle “Monitor‐analyse‐plan‐repair‐restore‐operate” is scientifically regulated with a degree of certainty. Approach is generic and can be applied to a variety of process equipment to ensure reliability through effective predictive maintenance.

Abstract
Purpose
When induction motors are considered, there is no specific cost model for net savings per year due to condition-based maintenance (CBM) covering various parameters such as downtime, energy, quality, etc. The purpose of this paper is to develop a cost model for the financial viability of the implementation of CBM for induction motors.
Design/methodology/approach
A literature review has been carried out to identify the existing failure modes of motor, available condition monitoring techniques, the usefulness of CBM and different maintenance models available. Then, a cost model considering all parameters has been proposed.
Findings
A cost model has been proposed for the maintenance of induction motors. Method for the economic evaluation of the model has also been suggested in the paper. The application of the model has been illustrated through a case study of a steel plant, which suggests that investment in the condition monitoring of induction motors increases the net profit of the organization.
Research limitations/implications
The proposed model is specifically designed for induction motors. All the motors under consideration are assumed to be of the same specifications, and fault in any motor is supposed to have the same effect on quality, cost, criticality, etc., of the operation and end product.
Practical implications
This paper will help the maintenance manager in decision making when maintenance action has to be carried out for a given motor under CBM for the better utilization of the equipment and resources. This paper also shows how to compute ROI on CBM investment.
Originality/value
The paper provides a cost model for the economic evaluation of implementing CBM for induction motors which will be useful to researchers and maintenance managers in effective decision making and maintenance planning. The methodology and the cost models are the original contribution of the authors.

Abstract
This study investigated the use of self‐assessments in predicting assessment centre outcome, looking at the difference between raw self‐assessments and self‐assessment accuracy scores. The subjects for the study were 60 engineers who attended a one‐day assessment centre in 1991‐1992 selecting trainers for an automotive manufacturer’s training programme. The measures used in the study were the assessor and candidate global exercise ratings, and it was found that self‐assessment accuracy was a better predictor of assessment centre outcome than the raw self‐assessment scores. It is suggested that if self‐assessments are to be used in assessment centres then they need to be thought of in conjunction with assessor ratings, and that self‐assessments may have a use in delivering feedback to candidates.

Abstract
Purpose
The assessment of fitness to drive after stroke is an emerging area of occupational therapy practice in Ireland. Despite this, little is known about occupational therapists’ evaluation practices, and there are no internationally agreed clinical guidelines to inform best practice. The purpose of this paper is to investigate occupational therapy evaluation practices for fitness to drive after stroke in Ireland.
Design/methodology/approach
This is a cross-sectional study design targeting occupational therapists working with people after stroke using an online survey. Summary and descriptive statistics were used to analyse the returned surveys.
Findings
In total, 47 occupational therapists participated. Off-road driving assessment was completed by 68 per cent of respondents. Functional assessment and non-driving-specific assessments were most widely used and perceived to be the most useful in informing the off-road assessment. A total of 89 per cent referred clients for on-road assessments; however, some referred without first completing an off-road assessment. The therapists who completed formal post graduate education/training in driving assessment reported greater confidence and competence in their skills and ability to assess fitness to drive. A vast majority of participants agreed that clinical guidelines regarding best practice in this area would be beneficial.
Research limitations/implications
A majority of occupational therapists are assessing fitness to drive after stroke in Ireland with non-driving-specific assessments and functional observations; however, there are many gaps and wide variations between services. Education/training in evaluating fitness to drive after stroke is recommended. The development of clinical guidelines to inform practice would facilitate a consistent approach nationally.
Originality/value
This is the first study completed in Ireland to investigate occupational therapy evaluation practices for fitness to drive after stroke.

This study aims to determine elements of telehealth that have the potential to increase costs for the health system in the short to medium term.
Abstract
Purpose
This study aims to determine elements of telehealth that have the potential to increase costs for the health system in the short to medium term.
Design/methodology/approach
A search of PubMed, EMBASE and Scopus databases was performed in May 2018 using broad terms for telehealth and economics. Articles were included if they identified and explained reasons for an increase in cost for telehealth services. Studies were categorised by economic analysis type for data extraction and descriptive synthesis.
Findings
Fourteen studies met inclusion criteria and were included in the review. These studies identified that increased health system costs were due to implementation costs (e.g. for equipment, software or staff training), increased use of other healthcare services (e.g. pharmaceutical services) and ongoing service costs (including staff salaries) resulting from telehealth being additive to traditional service (e.g. increased frequency of contact).
Originality/value
Telehealth is often assumed to be a cost-effective method of delivering healthcare, even to the point where direct cost savings are expected by decision makers as a result of implementation. However, this investigation suggests it does not routinely reduce costs for the health system and can actually increase costs at both implementation and ongoing service delivery stages. Health services considering implementing telehealth should be motivated by benefits other than cost reduction such as improved accessibility, greater patient centricity and societal cost–benefit.

Abstract
Purpose
The strategic importance of the purchasing function increases, as its task become more dynamic in various interfaces with different suppliers. Changes in these customer–supplier interfaces pose specific challenges. The purpose of this study is to investigate how the purchasing function handles the interplay of interface changes.
Design/methodology/approach
This study applies a qualitative single case study design. Data are collected through observations and interviews conducted before, during and after a concrete change of interface taking place between a buying firm and its suppliers and customers.
Findings
Three main findings are identified to redefine the tasks of the purchasing function. The first concerns the new ways of defining the purchasing tasks. The main issue is to balance tasks with the simultaneous changes influencing other interfaces and relationships. The second is the division and alignment of tasks in intra- and inter-organizational networks with regards to who decides and coordinates what. Third, the inter-connected performance relates to how other actors perform their tasks. For the purchasing function, managing supplier interfaces influences and is influenced by how the firm simultaneously manages its user interface.
Practical implications
For management, a new way to evaluate the performance of the purchasing function is needed by including relationship management and interactive capabilities.
Originality/value
This study contributes with new insights into how managing the dynamics of changing interfaces requires interactively defined purchasing tasks, division and alignment of tasks and inter-connected performance vis-à-vis others in the wider network setting.

Abstract
Purpose
This study aims to explore social and motor impairments of children with autism through the perspectives of their caregivers. Social and motor deficits among people with autism are well documented. There is support to suggest a reciprocal relationship between social and motor deficits among people with autism, in that social deficits can act as a barrier to motor skill development and motor deficits can act as a barrier to social skill development.
Design/methodology/approach
This study explored social and motor impairments of children with autism through the perspectives of eight caregivers of children with autism.
Findings
Many salient findings emerged from the interviews conducted with caregivers, particularly concerning the social and motor development of their children. The relationships between their children’s social and motor deficits were also highlighted.
Research limitations/implications
It is important that health-care professionals educate parents about the consequences of motor impairments or delays and their associations with the development of social skills. As such, routine motor skill monitoring and assessments by caregivers and health-care professionals should be encouraged.
Originality/value
To the best of authors’ knowledge, this is the first paper to investigate motor and social deficits of children with autism from the caregivers’ perspectives.

Abstract
Occupational therapists are concerned with how people perform across the various daily activities that are important to them. It is recognised within occupational therapy that the presence of illness or disability might affect this performance.In order to assess how a person complete a task and identify what is making it unsatisfying, the occupational therapist will observe the person engaged in familiar activities. The Assessment of Motor and Process Skills (AMPS) provides a standardised framework within which to make these observations. We have found the AMPS to be useful in assessing the performance of people with learning disabilities generally, as well as in assessing those with additional mental illness.We recognise that occupational therapy assessment plays a useful part in a wider multi‐professional, multi‐agency approach to identifying and managing the needs of people with learning disabilities.
