Self-initiated self-repairs of connected speech and novel vocabulary learning during the first year of recovery from aphasia: four longitudinal case studies

ABSTRACT Background Self-initiated self-repair of problems in speech production has been suggested to be associated with aphasia treatment gains and recovery, but the topic has been little studied. Similarly, the ability to learn novel words has been associated with anomia treatment benefits, although longitudinal data on such learning is lacking. Aims The present study’s aim was to examine whether and how self-initiated self-repairs in connected speech and the ability to learn novel vocabulary reflected recovery from aphasia as measured with cognitive-linguistic tests. Additionally, our aim was to explore whether self-initiated repair and novel word learning changed in parallel during recovery. Methods & Procedures Four people with aphasia (PWA) (2 anomic, 1 Wernicke, and 1 global aphasia) were tested in the subacute (11 to 68 days post stroke) and chronic (12 months post stroke) phases of recovery with cognitive-linguistic tests, connected speech tasks, and a computerized learning task. In the learning task, PWA associated 6 pseudowords with 6 unfamiliar referents. The associations were learned from an ambiguous setup with feedback. At both time points, learning was measured as correct immediate recognition of the items and recognition maintenance one week post-training. The proportion of self-initiated self-repairs and the proportion of unrepaired problems in connected speech were used as measures of self-repair behavior. Outcomes & Results All participants initiated self-repairs both in the subacute and chronic phases, and their self-repairs were most often related to aphasic difficulties in speech production. Between the subacute and chronic phases, self-repairs changed both in quality and quantity. The proportion of self-repair elements decreased in 4/4 participants and the proportion of unrepaired problem segments decreased in 3/4 participants. Of the participants, 3/4 showed significant novel word learning and/or maintenance already in the subacute phase and 4 /4 in the chronic phase. Conclusion Reduction in self-initiated self-repairs of speech reflected recovery from aphasia. Novel word learning improved during aphasia recovery from the subacute to the chronic phase. Novel word learning was possible even in subacute, severe aphasia and even in an ambiguous task set-up with no explicitly provided word-referent connections. Novel word learning and self-initiated self-repairs did not change in a clearly parallel manner; however, these findings need to be tested with a larger sample.

Manufacturers managing complexity during the digital servitization journey

PurposeManufacturers face various challenges and risks during their digital servitization (DS), due to the complexity caused by introducing breakthrough technologies, increasingly complex product-service solutions and new stakeholders in the business network. The process necessitates the implementation of various changes that usually happen over a long period of time. Using complexity management as a theoretical lens, this paper delves into manufacturers’ DS journeys and explores how manufacturers manage the associated complexities.Design/methodology/approachThis paper investigates the DS journey of two manufacturers in a longitudinal case study from 2014 to 2021.FindingsThree main complexity management actions during the DS journey were identified: shaping the digital service system, shaping the organization and shaping the network. Tied to different types of complexities, these actions demonstrate how manufacturers navigate their journey. The findings also reveal different complexity management approaches used at the different stages of this journey.Originality/valueThis paper offers a comprehensive framework for understanding complexity management in the DS journey, including the types of complexities, complexity management actions and complexity management approaches and their rationale. This paper shows that different requirements are created during emerge, consolidate and evolve stages of the DS journey. Manufacturers need a dynamic approach that considers changes in complexities and actions over time.

How secure memorization promotes expression: A longitudinal case study of performing Chopin’s Barcarolle, Op. 60

Experienced musicians can perform reliably from memory because they prepare performance cues (PCs) that allow them to recover when performance is disrupted. We describe a longitudinal case study in which a pianist (the second author) learned and performed Chopin’s Barcarolle, Op. 60, over a 12-year period. The pianist provided PC reports for 28 performances, starting a month before her first public performance. Shortly after each performance, she marked the features of the music that guided her playing (PCs) on a clean copy of the score, distinguishing five types of PC: structural, Schenkerian (tonal elaborations), expressive, interpretive, and basic. Structural PCs predominated at first and were later replaced by expressive and Schenkerian PCs. PCs were more frequent at structural boundaries than at other locations. This boundary effect was larger under typical, compared to atypical performance conditions, and increased over time, suggesting that the main function of PCs was promoting expression rather than guarding against mistakes. Although the pianist’s initial purpose in learning to use PCs was to have a safety net in case of memory failure, she was surprised to find that she enjoyed playing with PCs and believed they helped her to play more expressively.

Quality assurance dysfunctions

This article presents findings from a longitudinal case study of academic audit as enacted at a typical New Zealand university between 1994 and 2019. Academic audit is a higher education quality assurance methodology applied to New Zealand universities. The longitudinal study yielded findings that could not have been detected in a single, five-year audit cycle, in particular, that very similar recommendations were given more than once. Three sets of recurrent recommendations were studied in detail: closing the student feedback loop; monitoring PhD students’ progress and ‘quality assurance infrastructure and leadership’. The issues emerging from these three topics are ‘audit dysfunctions’, some of which are attributable to the institution and some of which belong to the external quality assurance agency. The audit dysfunctions are intended as a heuristic for improving the rigour and effectiveness of higher education quality assurance.

A dynamic view of strategic innovation for sustainability: A longitudinal case study of a luxury fashion engineering company

In this article, we study how a luxury fashion engineering company strategically introduced sustainability‐oriented innovations (SOIs) over time through an in‐depth longitudinal analysis of a leading Italian business‐to‐business (B2B) firm. We apply a strategic management perspective to this first‐tier engineering manufacturer to bring new insights into how upstream firms deploy SOIs and to what effect, thus determining long‐term technological choices in the industry. We observe that such innovations evolved dynamically from the process dimension to the supply chain and, lastly, to the product dimension, thereby spanning explorational, procedural and communicational practices. We find that the company sustained significant growth over a decade while implementing its sustainability transition, thanks to three elements: a broad and wide‐ranging experimentation in all areas of the company, a continuous dynamic process of learning‐by‐doing and a commitment of the top management to prioritize new sustainable practices. The propositions developed from this case study can inform future strategic analysis and management of SOIs in other firms/industrial sectors.

Who, what, where? The influence of the Integral Care Agreement (IZA) on established regional networks in Dutch healthcare

AbstractHealth and welfare organizations are encouraged to collaborate in regional, cross-domain networks. Although the literature has shown that policy changes can influence the effectiveness of existing networks, the impact of the Dutch Integral Care Agreement (Integraal ZorgAkkoord, IZA) is not yet known. We investigated this in a longitudinal qualitative case study of a network that has been in existence for a long time. The results show that after implementation of the IZA, a new overarching network at the healthcare administrative regional level was established. This led to uncertainty regarding the objective, composition, and sustainability of the existing network. A division emerged in the existing network between members who participated in the new network and those who did not. Organizations that participated in the new network questioned their participation in the existing network, to reduce administrative pressure. Organizations that only participated in the existing network doubted their participation because they lost sight of the network’s purpose and experienced a lack of transparency regarding decisions made in the new network. The Dutch national government and policymakers would do well to seek close alignment with practice when further developing the IZA.

The Hierarchical Configurations of Policy Networks: A Study of Decision-Making Processes in Urban Transport

This study sheds light on a commonly overlooked aspect in network literature: the potential for hierarchized behavior within networks. Providing a longitudinal case study of decision-making behavior in urban transport policy networks, the study also adds to calls for longitudinal studies in the field of public administration. By analyzing documents and interviews, the study reveals the gradual shift towards hierarchical decision-making within networked structures. Furthermore, it highlights how organizational variables shape networked behavior over time, both facilitating and constraining hierarchized behavior. Consequently, this article suggests that hierarchized and collaborative dynamics co-exist and co-evolve within policy networks.

Comparing Several P300-Based Visuo-Auditory Brain-Computer Interfaces for a Completely Locked-in ALS Patient: A Longitudinal Case Study

A Longitudinal Mixed Methods Case Study Investigation of the Academic, Athletic, Psychosocial and Psychological Impacts of Being of a Sport School Student Athlete.

Sport schools are popular environments for simultaneously delivering education and sport to young people. Previous research suggests sport school involvement to have impact (i.e. the positive/negative, intended/unintended and long/short-term outcomes, results and effects) on student athlete's holistic (i.e. academic, athletic, psychosocial and psychological) development. However, previous research is limited by (1) cross-sectional methods, (2) limited multidimensional assessments, (3) lack of consideration for athlete characteristics (e.g. sex) and (4) failure to evaluate how sport school features affect student-athlete impacts. The study, using a mixed methods case study approach, aims to (1) longitudinally evaluate the impact of sport school involvement on the holistic development of student athletes, (2) evaluate the impact on holistic development by student-athlete characteristics and (3) explore the features and processes of the sport-school programme that drive/facilitate holistic impacts. A longitudinal mixed methods design was employed across one full academic school year (33weeks). Six data-collection methods (i.e. online questionnaire, physical fitness testing battery, academic assessment grades, log diaries, field notes/observation and timeline diagram/illustration) were used to assess the academic, athletic, psychosocial and psychological impacts for 72 student athletes from one sport school in the United Kingdom (UK). Student athletes developed positive long-term holistic overall impacts (i.e. academically, athletically and personally), including maintaining stable and relatively high levels of sport confidence, academic motivation, general recovery, life skills, resilience and friends, family and free time scores. Despite positive impacts, juggling academic and sport workload posed challenges for student athletes, having the potential to lead to negative holistic impacts (e.g. fatigue, stress and injury). Positive and negative impacts were linked to many potential features and processes of the sport school (e.g. academic and athletic support services versus insufficient training load build-up, communication, coordination, flexibility and planning). Furthermore, when considering student-athlete characteristics, females had lower sport confidence, higher general stress and body image concerns and less general recovery than males and student athletes who played sport outside the school had lower general recovery. This mixed method, longitudinal study demonstrated sport school involvement resulted in many positive academic (e.g. good grades), athletic (e.g. fitness development), psychosocial (e.g. enhanced confidence) and psychological (e.g. improved resilience) impacts attributed to the academic and athletic support services provided. However, juggling heavy academic and athletic workloads posed challenges leading to negative impacts including fatigue, pressure, stress and injury. Furthermore, holistic impacts may be sex dependent and further support may be required for female student athletes in sport school environments. Overall, these findings demonstrate the complex nature of combining education and sport commitments and how sport schools should manage, monitor and evaluate the features of their programme to maximise the holistic impacts of sport-school student athletes.

A landscape of practice approach to enhance employability: insights from domestic and international postgraduates

PurposeDrawing on a theoretical framework of sustainable career ecosystem theory, our paper aims to consider how domestic and international postgraduates can enhance their employability through participation in a landscape of practice.Design/methodology/approachThe study employed an exploratory, longitudinal case study design to capture students' lived experiences on an 18-month Master of Professional Practice course at a higher education institution in New Zealand. The data collection procedure involved field note observations (months 1–4), a focus group (month 13) and narrative frames (months 16–18). The sample was domestic students from New Zealand (n = 2) and international students from Asia (n = 5).FindingsOne’s participation in multiple communities of practice represents their landscape of practice and a commitment to lifewide learning. Through participation in various communities of practice, domestic and international students can enhance their employability in three ways: (1) boundary encounters to develop social capital, (2) transcending contexts to enhance cultural capital, and (3) acknowledging the development of psychological capital and career agency.Originality/valueOur work offers one of the earliest empirical validations of sustainable career ecosystem theory. Expressly, communities of practice represent various contexts whereby employability capital is developed over time. Additionally, the postgraduate students themselves are portrayed as interconnected and interdependent actors, presenting a novel framing of such dependencies at the micro-level of the ecosystem. The practical implications come from informing universities of the value of a landscape of practice to enhance the employability of domestic and international students in preparation for sustainable careers and to promote the sustainability of the career ecosystem.

[Diffuse interstitial lung disease of possible occupational origin treated at the Navarra Health Service. Navarra, Spain, 2017-2022].

Diffuse interstitial lung disease (ILD) describes a broad group of pulmonary inflammatory and fibrosis disorders. Asbestosis and silicosis are the main causes linked to occupational exposure. The aim of this study was to estimate the proportion of cases with possible occupational origin and describe their exposure, clinical, and occupational status. We conducted a retrospective longitudinal study of ILD cases between 2017 - 2022 at the University Hospital of Navarra was conducted. Information was supplemented with interviews of cases with possible occupational origin. The occupational proportion was calculated, labor and clinical characteristics analyzed, by statistical comparison of percentages and means. Out of 1067 ILD cases, 56 had a possible occupational origin 5,2% (95% CI 3,9-6,6%). 36 (64,3%) corresponded to asbestosis, 15 (26,8%) to silicosis, and 5 (8,9%) to unspecified pneumoconiosis. The most frequent activities in silicosis were "stone cutting-carving" and in asbestosis "manufacture of iron products". The average age of asbestosis cases was higher than that of silicosis cases (78,2 vs. 67,3 years), as well as their clinical manifestation. Five cases (8,9%) had been recognized as occupational diseases. The implementation of a computer tool in medical records has made it possible to estimate the magnitude and assess the evolution of occupational ILD treated in the Public Health Service. Economic activities reflect the economic risk structure of the region. However, there is a lack of recognition of these diseases as occupational illnesses and they represent a preventable burden of respiratory disease.

Beyond lean production practices and Industry 4.0 technologies toward the human-centric Industry 5.0

PurposeBoth technological and human-centric perspectives need to be acknowledged when combining lean production practices and Industry 4.0 (I4.0) technologies. This study aims to explore and explain how lean production practices and I4.0 technologies may coexist to enhance the human-centric perspective of manufacturing operations in the era of Industry 5.0 (I5.0).Design/methodology/approachThe research approach is an explorative and longitudinal case study. The qualitative data collection encompasses respondents from different job functions and organizational levels to cover the entire organization. In total, 18 interviews with 19 interviewees and five focus groups with a total of 25 participants are included.FindingsIdentified challenges bring forth that manufacturing organizations must have the ability to see beyond lean production philosophy and I4.0 to meet the demand for a human-centric perspective in socially sustainable manufacturing in the era of Industry 5.0.Practical implicationsThe study suggests that while lean production practices and I4.0 practices may be considered separately, they need to be integrated as complementary approaches. This underscores the complexity of managing simultaneous organizational changes and new digital initiatives.Social implicationsThe research presented illuminates the elusive phenomena comprising the combined aspects of a human-centric perspective, specifically bringing forth implications for the co-existence of lean production practices and I4.0 technologies, in the transformation towards I5.0.Originality/valueThe study contributes to new avenues of research within the field of socially sustainable manufacturing. The study provides an in-depth analysis of the human-centric perspective when transforming organizations towards Industry 5.0.

Integrated Reporting and the experience of the Pilot Programme: perspective of an Italian pioneer company over ten years

Purpose This study aims to propose a longitudinal analysis of motivations for Integrated Reporting (IR) adoption, internal changes, the benefits of IR implementation and compliance challenges. Design/methodology/approach The authors analyse a longitudinal case study of an Italian-listed company (Eni) participating in the IR-Pilot Programme (PP) and covering 10 years of IR adoption. The analysis was based on a mixed-method approach that included semi-structured interviews, content analysis of annual reports and triangulation with other data sources. Results are discussed regarding institutional theory, legitimacy theory and diffusion of innovation theory. Findings The study suggests that motivations for adopting IR change over time and participation in the IR-PP helps Eni acquire a comprehensive and substantial integrated view of value creation over time, makes integrated culture a key factor for strategic business sustainability and confirms the readiness of early adopters to comply with the non-financial Directive (NFD). Originality/value This study, among the few longitudinal case studies, provides organisations, regulators and academics with insights into the motivations driving the successful adoption and implementation of IR and the NFD. The results may help companies consider one of the tools currently deemed to bring sustainability into action and participation in pilot groups.

Adopting, implementing and assimilating coproduced health and social care innovations involving structurally vulnerable populations: findings from a longitudinal, multiple case study design in Canada, Scotland and Sweden

BackgroundInnovations in coproduction are shaping public service reform in diverse contexts around the world. Although many innovations are local, others have expanded and evolved over time. We know very little, however, about the process of implementation and evolution of coproduction. The purpose of this study was to explore the adoption, implementation and assimilation of three approaches to the coproduction of public services with structurally vulnerable groups.MethodsWe conducted a 4 year longitudinal multiple case study (2019–2023) of three coproduced public service innovations involving vulnerable populations: ESTHER in Jönköping Region, Sweden involving people with multiple complex needs (Case 1); Making Recovery Real in Dundee, Scotland with people who have serious mental illness (Case 2); and Learning Centres in Manitoba, Canada (Case 3), also involving people with serious mental illness. Data sources included 14 interviews with strategic decision-makers and a document analysis to understand the history and contextual factors relating to each case. Three frameworks informed the case study protocol, semi-structured interview guides, data extraction, deductive coding and analysis: the Consolidated Framework for Implementation Research, the Diffusion of Innovation model and Lozeau’s Compatibility Gaps to understand assimilation.ResultsThe adoption of coproduction involving structurally vulnerable populations was a notable evolution of existing improvement efforts in Cases 1 and 3, while impetus by an external change agency, existing collaborative efforts among community organizations, and the opportunity to inform a new municipal mental health policy sparked adoption in Case 2. In all cases, coproduced innovation centred around a central philosophy that valued lived experience on an equal basis with professional knowledge in coproduction processes. This philosophical orientation offered flexibility and adaptability to local contexts, thereby facilitating implementation when compared with more defined programming. According to the informants, efforts to avoid co-optation risks were successful, resulting in the assimilation of new mindsets and coproduction processes, with examples of how this had led to transformative change.ConclusionsIn exploring innovations in coproduction with structurally vulnerable groups, our findings suggest several additional considerations when applying existing theoretical frameworks. These include the philosophical nature of the innovation, the need to study the evolution of the innovation itself as it emerges over time, greater attention to partnered processes as disruptors to existing power structures and an emphasis on driving transformational change in organizational cultures.

Heterogeneity in families with ATTRV30M amyloidosis: a historical and longitudinal Portuguese case study impact for genetic counselling

Background Hereditary transthyretin amyloidosis (ATTRv amyloidosis) is an inherited disease, where the study of family history holds importance. This study evaluates the changes of age-of-onset (AOO) and other age-related clinical factors within and among families affected by ATTRv amyloidosis. Methods We analysed information from 934 trees, focusing on family, parents, probands and siblings relationships. We focused on 1494 female and 1712 male symptomatic ATTRV30M patients. Results are presented alongside a comparison of current with historical records. Clinical and genealogical indicators identify major changes. Results Overall, analysis of familial data shows the existence of families with both early and late patients (1/6). It identifies long familial follow-up times since patient families tend to be diagnosed over several years. Finally, results show a large difference between parent-child and proband-patient relationships (20–30 years). Conclusions This study reveals that there has been a shift in patient profile, with a recent increase in male elderly cases, especially regarding probands. It shows that symptomatic patients exhibit less variability towards siblings, when compared to other family members, namely the transmitting ancestors’ age of onset. This can influence genetic counselling guidelines.

Implementing Digital Innovations: Overcoming Organizational Challenges

While real estate owners play a significant role in advancing digitalization and sustainability within the sector, there's limited understanding of their innovation processes. This article aims to increase understanding on the innovation processes and dynamic capabilities in real estate owner organizations. The article examines a longitudinal case study within a prominent Swedish real estate owner known for significant investments in smart building technologies. Despite these investments, practical benefits face hurdles, reflecting broader challenges in real estate sector digitalization projects. These obstacles include top-down innovation focus, limited cross-functional and user-centric innovation, innovation process discontinuities, ambiguous innovator roles, hierarchical communication, resource constraints, and uncertainties in technology implementation. The study emphasizes the inclusion of diverse perspectives in innovation processes and suggests further research on organizational and user-centric aspects. It contributes to real estate and facility management literature by proposing potential solutions to innovation processes, offering valuable insights for industry practitioners and researchers alike.

Change in a project-based organization: The mutual shaping of institutional logics and change programs

Modern organizational transformations increasingly rely on change programs led by the introduction of new information technology. Managing these information technology-based change programs within project-based organizations presents unique challenges due to the division between ongoing business processes and temporary project activities. This study uses an institutional logics perspective to understand how a project-based organizational context shaped and was shaped by an information technology-based change program. Through a three-year longitudinal case study on the interaction between a project-based organization and its information technology program, our findings reveal that institutional logics prevailing in the project-based organization significantly influenced the program's implementation. In turn, the information technology program acted as a catalyst for change, creating a competitive environment where two primarily segmented logics—a project organizing logic and an asset management logic—competed for dominance. The conflict between these logics led to new beliefs, values, and practices being dominant, marking a shift in balance between the two logics. Our findings contribute to increasing understanding of the dynamic interplay between project-based organizations and information technology-based change programs, shedding light on their mutual evolution over time and offering a deeper understanding of transformative change within project-based organizations.
