There is growing literature on the application of Dialectical Behaviour Therapy (DBT) with adults with intellectual disabilities (IDs). To draw upon the evidence-base from mainstream approaches, adapted interventions must remain true to their theoretical foundations and retain key components. The purpose of this paper was to establish the extent to which DBT has been adapted for adults with ID, and whether existing adapted protocols can still be considered DBT.

The theoretical underpinnings and key components of DBT were identified. Six DBT studies were critiqued according to these criteria.

In terms of content, only one intervention comprised all necessary elements. All of the remaining interventions included a skills group; two included individual therapy and another two included group consultation. None of the remaining interventions provided 24-h telephone support. Furthermore, none of the studies explicitly described using dialectical strategies.

To the best of the authors’ knowledge, this is the first paper to critically examine the evidence-base for the use of DBT in ID, particularly its fidelity.

In providing specialized care for older individuals the skills of many disciplines are often needed to provide the most effective care. At the time of referral, it is not always clear which patients are best served by a medical approach and which ones require psychiatric input. When patients are referred to the less appropriate service, diagnosis and treatment may be delayed to the detriment of the patient. A wide spectrum of specialized services for the elderly is offered at the Hamilton Health Sciences Corporation, a four‐site teaching hospital in Ontario. The authors describe the development of a common intake process which provides rapid triage to the most appropriate services, and facilitates a combined medical and psychiatric approach where indicated. The end result is a single entry point for referrals, more efficient triage and a net reduction in the number of staff needed to accept and process referrals.

Although there is a lack of research on instruction that aims at facilitating students’ use of questioning with peers, many early childhood social studies textbooks and resources, include activities and lessons recommending students conduct interviews with an explicit assumption that young students are capable of formulating and using questions in the context of an interview. In these instances, no suggestions or ideas are given to teachers regarding instruction that will encourage and facilitate students’ questioning. The purpose of this study was to determine if the levels of social studies interview questions second graders formulate and use can be increased with questioning instruction in terms of quality, which is defined as depth of response, and in terms of quantity. This study generated research hypotheses that could be investigated in future research on instruction aimed at increasing young children’s questioning abilities as demonstrated in social studies.

In response to the call for research on customer experience across the customer journey, this study aims to analyze and compare the effects of perceived quality on customer satisfaction among the different stages of search, experience and credence services.

This paper constructs a formation model of customer satisfaction based on service stages. Data on perceived quality and customer satisfaction in different stages of search, experience and credence services was collected through experiments and practical survey and the model was empirically tested through multiple linear regression.

The results show that perceived quality in the preparation and departure stages of search and credence services has a greater influence on customer satisfaction than in the delivery stage. While compared to the preparation stage, the perceived quality in the delivery and departure stages of experience service has a greater influence on customer satisfaction.

This research will help service firms optimize the allocation of service resources according to the importance of different service stages within the three indicated service types, promoting customer satisfaction.

This is the first study of its kind to compare the effects of perceived quality on customer satisfaction among the stages of search, experience and credence services.

A survey of project scheduling problems since 1973 limited to work done specifically in the project scheduling area (although several techniques developed for assembly line balancing and job‐shop scheduling can be applicable to project scheduling): the survey includes the work done on fundamental problems such as the resource‐constrained project scheduling problem (RCPSP); time/cost trade‐off problem (TCTP); and payment scheduling problem (PSP). Also discusses some recent research that integrates RCPSP with either TCTP or PSP, and PSP with TCTP. In spite of their practical relevance, very little work has been done on these combined problems to date. The future of the project scheduling literature appears to be developing in the direction of combining the fundamental problems and developing efficient exact and heuristic methods for the resulting problems.

For many applications, including space applications, the usability and performance of a component is dependent on the surface topology of the additively manufactured part. The purpose of this paper is to present an investigation into minimizing the residual surface roughness of direct metal laser sintering (DMLS) samples by manipulating the input process parameters.

First, the ability to manipulate surface roughness by modifying processing parameters was explored. Next, the surface topography was characterized to quantify roughness. Finally, microthruster nozzles were created both additively and conventionally for flow testing and comparison.

Surface roughness of DMLS samples was found to be highly dependent on the laser power and scan speed. Because of unintended partially sintered particles adhering to the surface, a localized laser fluence mechanism was explored. Experimental results show that surface roughness is influenced by the varied parameters but is not a completely fluence driven process; therefore, a relationship between laser fluence and surface roughness can be incorporated but not completely assumed.

This paper serves as an aid in understanding the importance of surface roughness and the mechanisms associated with DMLS. Rather than exploring a more common global energy density, a localized laser fluence was initiated. Moreover, the methodology and conclusions can be used when optimizing parts via metal additive manufacturing.

The purpose of this paper is to detail the design and first use of a force transducer device to study the development of forces during the laser-powder bed fusion (L-PBF) process from which residual stresses can be inferred.

The proposed novel device consists of an array of load cells for in-situ measurement of forces over time during the L-PBF additive manufacturing process. Measurements of the developed forces layer by layer were recorded in a first build using a 67-degree rotating scan strategy using Inconel 625 build material.

Preliminary experimental results from in-situ measurements using a 67-degree rotating scan strategy showed that the forces induced in the first five layers represented approximately 80% of the maximum on completion of the build and were distributed such as to induce concave deformation of the part, i.e. tension in the centre and compression at the edges of the part.

This paper describes a novel device for in-process measurement of the spatial distribution and time-varying nature of the forces induced during the L-PBF process as well as an evaluation of the residual forces following the completion of the build.

This paper aims to analyze the political background of the Hawthorne criticisms, positing that the political atmosphere of the 1940s, influenced by the decline of the new deal liberalism and the rise of the conservative coalition, stimulated scholars to challenge the Hawthorne studies.

Primary sources used in the guise of archival commentaries, journal articles and other published works (books and book chapters). Secondary sources are offered to provide additional insight and context.

The findings show that politics unnecessarily discredited Mayo. As a result, contemporary scholars failed to recognize Mayo’s work as an important part of the basis for modern management theory.

The purpose of the research is to look into the political context of the Hawthorne studies to understand how management practice and research is impacted by ongoing political issues.

To date, no work has fully accounted for or understood the political climate of the time in considering the criticisms of the Hawthorne studies. By more fully understanding the political context, scholars can reevaluate the weight they place on the then criticisms of the Hawthorne studies.

The winter 1991 issue of Reference Services Review featured an annotated bibliography of literature on Christopher Columbus from 1970 to 1989. That literature covered such topics as Columbus' ancestry, heraldry, and the locations of both his American landfall and burial site. This annotated checklist focuses mainly on Columbus' legacy, on works that offer a dissenting point of view from most previous writings about Columbus (and on works that react to the dissenters), on material written by Native American and other non‐European authors, and on materials published by small and noncommercial presses.

Developing ambidexterity as a dynamic capability is important for firms to sustain their competitive advantage. Moreover, this capability allows firms to build the resiliency to mitigate enterprise risks. The purpose of this paper is to apply two main theoretical frames from the strategy literature, dynamic capabilities, and organizational ambidexterity, to supply chain management (SCM) to examine mitigation strategies for supply chain (SC) disruptions. The authors empirically investigated how the firm’s SC ambidexterity is developed through a dynamic capability-building process and how this, in turn, can mitigate the negative impact of SC disruptions and improve business performance.

This study conducted a field survey to answer the research questions as there exists no archival database with detailed information on ambidextrous SC strategies and dynamic capability. A total of 316 usable responses were received from managers working in the SC area. Confirmatory factor analysis and structural equation modeling were run on SPSS (version 16.0) and AMOS (version 18.0) to test the hypotheses to answer research questions.

Overall, the results of the study confirmed that a dynamic SC capability-building process is an antecedent of SC ambidexterity, and that SC ambidexterity is important to firms as it mitigate the negative impact of SC disruptions and enhance business performance. To take advantage of an ambidextrous SC, through minimizing the negative impact of SC disruptions and maximizing firm performance, firms should continually search for creative ways to satisfy new market needs and adapt to the fast changing business environment.

This study applied a dynamic capability-building process and ambidexterity to SCM. From the resilient SC perspective, the study found that the ability to effectively utilize existing resources and create novel strategies for problem solving plays a critical role in addressing SC disruptions.
