    Supply chains are under pressure to meet performance expectations under conditions in which access to the global network of suppliers and customers is fluid. Most studies accept the importance of agility to enhance performance using flexibility as a key dimension. Moreover, based on literature and empirical implications, it is essentially noticeable that there is an agreement on the need for flexibility in manufacturing to address both internal changes at the manufacturing echelon (e.g., a variation of process times) and external uncertainties (e.g., availability of ingredients, delivery schedules).However, there is a lack of adoptable metrics of manufacturing flexibility that can be used to evaluate manufacturing flexibility’s impact to enhance TH and reduce cost, both at the manufacturing echelon and the supply chain as a system as well as its impact on other echelons. Therefore, focusing on manufacturing flexibility as a competitive strategy induces a driving force for the success of the performance of supply chains. The purpose of this research is to present an applicable methodology for the evaluation of flexibility in a supply chain called Flexible Discrete Supply Chain (FDSC). The FDSC structure consists of a supplier, manufacturer, distributor, and customer as its conceptual model. Two main performance indicators – TH and cost are used to study the FDSC performance. This study utilizes four dimensions: volume, delivery, mix, and innovation (VDMI) flexibility. Quality function deployment is used to translate the dimensions of flexibility to key metrics that can be controlled in a discrete-event simulation (DES) model. The DES model is used to generate data, and for configuring VDMI metrics. The data is used for further sensitivity analysis. The developed methodology is verified and validated using data from a real case study. It is applicable to all supply chains within the FDSC criteria. This study contributes to the body of knowledge of supply chain flexibility through technical, methodical, and managerial implications. It clearly illustrated scenarios and provided guidelines for operations managers, to test among VMDI flexibility to maximize TH constrained by cost. Key directions for future research are identified

    Being-blind-in-the-world: a phenomenological analysis of blindness and a formulation of new objectives in rehabilitation

    Get PDF
    This work contains a phenomenological analysis of blindness, providing a basis for the evaluation of rehabilitation practice in South Africa and the formulation of future objectives in the field. Stereotypes of blindness associated with the perspectives of consumerism, scientific research, and social casework are analysed. Theories of blindness proposed by Braverman, Carroll, Monbeck, Foulke, Jernigan, and Scott are critically examined. The findings give substance to the claim that professional workers with the blind are guided in their attitudes and actions by images and meanings originating from these sources. All such preconceptions are rejected in favour of a description of blindness in terms of actual experience. An in-depth study of experience reveals how the nature of perception determines the blind person's relationship with the physical environment, with other people, and with the welfare system. In each sphere limitations arise which are overcome by specific responses and appropriate techniques. These observations lead to the formulation of a set of basic principles of rehabilitation, stressing the importance of individualization, self-reliance, assertiveness, versatility, and a personal interpretation of blindness. The relevance of traditional modalities is explained, while the need to expand rehabilitation teaching to include assertive skills training and various types of vocational instruction is emphasized. Current rehabilitation practice in South Africa is evaluated, comparisons being drawn with programmes offered by Beit Halochem in Tel Aviv, Arkansas Enterprises for the Blind, and the Center for Independent Living of the New York Infirmary. South African training is characterized as fostering the independence of the individual. Negative features are the lack of an effective delivery system and failure to meet the priority needs of certain groups. This prepares the way for a case study in which the redevelopment of rehabilitation services for the blind in South Africa .is discussed, beginning with the establishment of a new national rehabilitation centre. Amongst other matters, the study deals with negotiations to circumvent restrictive legislation, funding through a system of corporate sponsorship, and purposeful architectural design. The rehabilitation centre is viewed as the first component of a broader strategy to provide rehabilitation training to all blind people in South Africa, incorporating national, urban, rural, and specialized services. The successful implementation of any action plan will require the participation of blind people themselves by way of a disability rights movement. Finally, attention is focused on the effect of South African racial policies on welfare work. The principle of equal opportunity cannot be practised under present legislation

    AN EXPLORATION INTO ADDICTIONS COUNSELLOR TURNOVER IN MANITOBA: A NARRATIVE INQUIRY

    Get PDF
    Addiction is a growing concern particularly in Manitoba where the rate is higher than the national average. Individuals are accessing addictions services at steadily increasing rates therefore Counsellors will be needed to deal with this increase. International literature reports high turnover among addictions counsellors, with detrimental effects on service delivery. This thesis aims to enhance an understanding of the ways in which contextual features influence how and when counsellors leave the field of addiction. A critical narrative approach was adopted that aligned with a constructivist paradigm. Two semi structured narrative interviews were conducted with four participants. Common themes that emerged were: education playing a major role in the difficulties experienced by the participants, the impact of centralized decision-making, lack of support from management and coworkers, systemic constraints making work in addictions challenging, as well as each participant being uncertain about entering, leaving and returning to the field of addictions. Findings indicate that turnover is non-linear and contextually situated

    Psychological approaches to understanding and promoting recovery in psychosis and bipolar disorder:a mixed-methods approach

    Get PDF
    BackgroundRecovery in mental health is a relatively new concept, but it is becoming more accepted that people can recover from psychosis. Recovery-orientated services are recommended for adult mental health, but with little evidence base to support this. ObjectivesTo facilitate understanding and promotion of recovery in psychosis and bipolar disorder (BD), in a manner that is empowering and acceptable to service users. MethodThere were six linked projects using qualitative and quantitative methodologies: (1) developing and piloting a service user-defined measure of recovery; (2) a Delphi study to determine levels of consensus around the concept of recovery; (3) examination of the psychological factors associated with recovery and how these fluctuate over time; (4) development and evaluation of cognitive–behavioural approaches to guided self-help including a patient preference trial (PPT); (5) development and evaluation of cognitive–behavioural therapy (CBT) for understanding and preventing suicide in psychosis including a randomised controlled trial (RCT); and (6) development and evaluation of a cognitive–behavioural approach to recovery in recent onset BD, including a RCT of recovery-focused cognitive–behavioural therapy (RfCBT). Service user involvement was central to the programme. ResultsMeasurement of service user-defined recovery from psychosis (using the Subjective Experience of Psychosis Scale) and BD (using the Bipolar Recovery Questionnaire) was shown to be feasible and valid. The consensus study revealed a high level of agreement among service users for defining recovery, factors that help or hinder recovery and items which demonstrate recovery. Negative emotions, self-esteem and hope predicted recovery judgements, both cross-sectionally and longitudinally, whereas positive symptoms had an indirect effect. In the PPT, 89 participants entered the study, three were randomised, 57 were retained in the trial until 15-month follow-up (64%). At follow-up there was no overall treatment effect on the primary outcome (Questionnaire about the Process of Recovery total; p = 0.82). In the suicide prevention RCT, 49 were randomised and 35 were retained at 6-month follow-up (71%). There were significant improvements in suicidal ideation [Adult Suicidal Ideation Questionnaire; treatment effect = –12.3, 95% confidence interval (CI) –24.3 to –0.14], Suicide Probability Scale (SPS; treatment effect = –7.0, 95% CI –15.5 to 0) and hopelessness (subscale of the SPS; treatment effect = –3.8, 95% CI –7.3 to –0.5) at follow-up. In the RCT for BD, 67 participants were randomised and 45 were retained at the 12-month follow-up (67%). Recovery score significantly improved in comparison with treatment as usual (TAU) at follow-up (310.87, 95% CI 75.00 to 546.74). At 15-month follow-up, 32 participants had experienced a relapse of either depression or mania (20 TAU vs. 12 RfCBT). The difference in time to recurrence was significant (estimated hazard ratio 0.38, 95% CI 0.18 to 0.78; p < 0.006). ConclusionsThis research programme has improved our understanding of recovery in psychosis and BD. Key findings indicate that measurement of recovery is feasible and valid. It would be feasible to scale up the RCTs to assess effectiveness of our therapeutic approaches in larger full trials, and two of the studies (CBT for suicide prevention in psychosis and recovery in BD) found significant benefits on their primary outcomes despite limited statistical power, suggesting definitive trials are warranted.

    Supporting older adults to STAY ACTIVE AT HOME:process, effect and economic evaluation of a reablement training program for homecare staff

    Get PDF
    Many older adults prefer to continue living at home for as long and as independently as possible. Promoting independence increasingly received attention in Dutch homecare, but appears quite a challenge. Homecare staff is traditionally accustomed to focusing on what older adults can no longer do and, with the best of intentions, tends to take over activities. Reablement - or 'helping people help themselves (again)' - is an innovative approach to improving a person's (physical) functioning and increasing his or her independence in meaningful activities. This thesis evaluates the reablement training program 'Stay Active at Home'. About 300 nurses and domestic workers were trained in reablement. The staff and their clients were compared to a group who did not receive training. Although staff were positive about the training, no effects of the training were found in clients (sedentary behavior, functioning, falls, and quality of life) and staff (self-efficacy and outcome expectations) and in terms of costs. The lessons from this study contribute to the further development of programs to promote independence in older adults

    STRATEGIC DECISION-MAKING IN A TURBULENT BUSINESS ENVIRONMENT: A DYNAMIC CAPABILITIES FRAMEWORK FOR QUANTITY SURVEYING PROFESSIONAL SERVICE FIRMS IN IRELAND

    Get PDF
    The construction industry contributes significantly to the socio-economic development of nations through infrastructure development, and job creation culminating into the growth of Gross Domestic Product (GDP). Quantity Surveying Professional Service Firms (QSPSFs) play a critical role in the construction industry by ensuring that projects are delivered within cost, required quality and duration by providing technical and knowledge-intensive services to clients, contractors and stakeholders. Irish QSPSFs are facing challenges such as tender price inflation, intense competition, a skills shortage and disruptive technology. These challenges coupled with the cyclicality of the sector create a turbulent business environment for Irish QSPSFs, yet there remains a paucity of empirical evidence pertaining to how strategic decisions are made by these firms. Strategic planning is critical to addressing the challenges confronting business organisations such as the Irish QSPSFs; however, to date strategic planning has focused to a greater extent on manufacturing, oil and gas, retail, consumer products and light manufacturing, whereas there remains limited empirical investigation within the construction industry. This study aims to address this gap by examining the strategic decision-making process of Irish QSPSFs operating in the changing environment of the construction industry. What sets the research apart is that a Dynamic Capabilities (DC) perspective has been used with focus on sensing; seizing; and transformation, culminating into its integration into the development of a strategic decision-making framework. This study is entrenched in the pragmatist philosophical stance with emphasis on the positivist and interpretivist position and adopts mixed method by using quantitative and qualitative approaches over two phases. The first phase involves a survey administered with support from the Society of Chartered Surveyors Ireland (SCSI) to 350 member practices whereby a single senior Quantity Surveyors (QS) in each practice was invited to participate. Seventy-two usable survey questionnaires completed by respondents were prepared for data analysis. The second phase of the research comprised of interview with ten chief executives or managing directors of Irish QSPSFs. The study found the most preferred strategic choice at the corporate level of QSPSFs as the expansion of services to new markets and sectors. At the business level, the investigation discovered the differentiation of services as the main strategic choice of QSPSFs. Furthermore, participation in strategic decision-making is very critical to the success of strategy formulation in organisations. This study identifies the factors that drive participation in strategic decision-making as the knowledge and competence of staff; personality traits; and the ability of people to make decision at the operational level of the organisation. The investigation also found that strategic change has occurred in QSPSFs over the past ten years. This strategic change is attributable to turbulent environmental conditions such as economic recession, in particular reference to the prolong economic recession 2008-2013. The investigation identified the specific strategic changes that occurred in QSPSFs as growth and expansion into new markets; agglomeration, and changes in the ownership and management structure. The negative and positive impacts of economic recession on QSPSFs have also been identified in this investigation. For instance, a radical shift in strategic response from being proactive to reactive; and self-preservation of ownership structure are the ii adverse effects of economic recession identified by the study while knowledge acquisition; and risk profiling for identification and capturing of opportunities are the positive impacts of economic recession. The study found significant statistical evidence to confirm a strong relationship between the turbulent business environment and the strategic decision-making process characteristics of QSPSFs. A strategic decision-making framework was developed on the basis of field work undertaken which was subsequently validated by respondent practices. The framework is the first of its kind pertaining to construction PSFs
