This study investigated temporal changes in movement strategy and performance during fatiguing short-cycle work. Eighteen participants performed six 7-min work blocks with repetitive reaching movements at 0.5 Hz, each followed by a 5.5-min rest break for a total duration of 1 h. Electromyography (EMG) was collected continuously from the upper trapezius muscle, the temporal movement strategy and timing errors were obtained on a cycle-to-cycle basis, and perceived fatigue was rated before and after each work block. Clear signs of fatigue according to subjective ratings and EMG manifestations developed within each work block, as well as during the entire hour. For most participants, timing errors gradually increased, as did the waiting time at the near target. Changes in temporal movement strategy were negatively correlated with changes in the level and variability of EMG, suggesting that an adaptive temporal strategy offset the development of unstable motor solutions in this fatiguing, short-cycle work.Practitioner Summary: Sustained performance of operators is essential to maintain competitiveness. In this study of repetitive work, participants gradually changed their temporal movement strategy, for possibly alleviating the effects of fatigue. This suggests that in order to effectively counteract fatigue and sustain performance, industrial production should allow extensive spatial and temporal flexibility.

The capacity to deal with digital transformation is a valuable asset for established organizations, and employees play a crucial role in this process. This study contributes to the understanding of employees’ sensemaking of digital transformation in the tour operating industry. Using prior digital transformation research, construal-level theory (CLT), and dynamic change perspectives, our scholarly work focuses on the complexities of organizational change in a digital transformation context. Although employees generally support digital transformation, our findings show that their perceptions change over time across a range of specific challenges experienced during the employee change journey. Our findings stress the importance of adopting a social exchange lens in digital transformation knowledge as this represents deep structure change that might cause well-designed transformation processes to fail. Implications for hospitality and tourism management are discussed.

The aim of this paper is to understand how employees, in their role of follower of change, frame upcoming change by studying the prospective stories they tell (n=110). This study complements the dominant retrospective approach to the research of employees’ change sensemaking. We incorporate forward-looking awareness into organization theories and add to the scholarly interest in prospection (Gioia & Patvardhan, 2018). This could lead to a better understanding of followers’ adaptation- or rejection intentions in response to change initiatives (Konlechner et al., 2018). Theoretical background Employees experience continuous shifts in relationships and organizational roles (Van der Smissen et al., 2013). This ‘turbulence’ triggers intensive sensemaking (Weick, 1995) of what is going on and how to respond. In uncertain times, employees often form expectations towards the future based on their remembered experiences from the past, and organizational change literature has traditionally taken a retrospective approach to understand followers’ change sensemaking (Boje, 2008). However, traditional literature neither provides elaborate insight in followers’ attempts to build scenarios for their future, nor do they add to the understanding of followers’ hopes, dreams, concerns, or fears (which all have a future time orientation) in the context of upcoming change. Scholars suggested that the current radical changes employees face cannot be anticipated easily from a mere retrospective approach (MacKay & Chia, 2013). In reality, employees think as often about their future as they do about their past and tend to create complex, temporal ranges of future orientations (Klein, 2013). Hence, researchers have critiqued the omission of the possible impact of beliefs and expectations about the future (e.g., Kaplan & Orlikowski, 2013), and have developed complementary notions to develop temporal sensemaking to challenge us to “mentally reverse the arrow of time” (Lord et al., 2013, p. 4) by focusing on expected futures to understand the present. The acknowledgement of prospective sensemaking directing attitudes and behaviors today (Maitlis & Christianson, 2014), expectedly offers novel insights to those interesting in understanding employees’ change behaviors. Design/Methodology/Approach/Intervention. A narrative approach is used to capture 110 individuals’ idiosyncratic and cultural sensemaking efforts (Pentland, 1999). We created a digital research set-up in which participants were guided to write a narrative that resembles a biographical account about a fictive colleague. Participants were introduced to the task by a video message from the fictive focal actor “Jim” and a video announcement of upcoming change by a fictive CEO in a Zoom-call for the entire organization. By means of the Story Completion Method, participants were asked “how does the story end?” and invited to write subsequent chapters on how they expected this story to continue, and how the roles and responses of the different actors would unfold along the way. Research context is provided by the Dutch travel industry in which organizations are dealing with heavy consequences of the COVID19 pandemic. Results will be available by November 2021. Limitations Qualitative research is less generalizable given the sample size and scope. Besides, the method requires specific skills and a level of empathy with the scenario, this proved to be difficult for some of the participants. In our analysis we therefore have to account for a difference between prospective sensemaking efforts and mere extrapolations of past experiences. Research/Practical Implications This study reveals potentialities that are considered to be available in the future. For change leaders, it is helpful to understand these potentialities as they reveal explanations for differences in followers’ prospective change strategies, and diverse anticipative responses to change efforts. We extend the concept of prospective sensemaking, and explore its use in a follower-based, dynamic context of organizational change. Originality/Value Advancing the concept of follower-based prospective sensemaking is important as it could provide explorative notions that illustrate the formation and use of expectations. Especially interesting is the context Dutch travel industry context as employees at the time of data collection experienced a ‘cosmology episode’ triggering sudden loss of meaning and coherence. This is perceived to be a critical trigger for sensemaking in the absence of past empirical experience (as no one experienced a pandemic and resulting business challenges before, but rather relies on transcendent belief systems in the face of future uncertainty (Weick, 1993)).

PurposeThe purpose of this paper is to develop a framework to understand organisational rhythm as a stimulus for further study into organisational change.Design/methodology/approachThis paper studies the experiences of the medical discipline colleges in the Netherlands as they underwent significant reorganisation and transfer of ministerial authority. The data set consists of correspondence, reports and tapes of the meetings over 14 months and interviews with 26 employees.FindingsThis research identified five sub-themes of rhythm (emphasis, intonation, pace, period and repetition). Putting these together, the authors present a framework to understand organisational rhythm during organisational change.Research limitations/implicationsThis study begins to develop understanding of how rhythms function but the authors did not compare multiple rhythms in this study.Practical implicationsThe authors argue that by unpacking and exploring in more detail the sub-themes of rhythm (emphasis, intonation, pace, period and repetition), the authors can help to explain why complex change management initiatives may stall or fail to gain traction. By understanding the concept of rhythm as movement, the authors can offer recommendations to organisations about how to move forward and overcome challenges associated with progress.Originality/valueIn this paper, the authors make an important distinction between rhythm in terms of movement and flow of activity, which has often been overlooked by research, which focusses on the temporal aspects of organisations, which the authors classify as frequency – relating to the sequencing and duration of change.

Global climate change (CC) affects marine mammals, such as cetaceans, by exposing them to an altered marine environment. Cetaceans are indirectly influenced by CC (e.g. through their prey, warmer environment). They are indicator species, significant to marine ecosystems and one of the most endangered vertebrate groups on this planet. Since oceanic water temperatures have increased, a noticeable shift in diversity of cetaceans present in marine hotspots is expected. In this paper, the community structure (occurrence) of cetacean species present around São Miguel Island, Portugal were investigated to contribute to the current understanding of the effects of CC on cetaceans.

Background: Everyday exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from wireless devices such as mobile phones and base stations, radio and television transmitters is ubiquitous. Some people attribute non-specific physical symptoms (NSPS) such as headache and fatigue to exposure to RF-EMF. Most previous laboratory studies or studies that analyzed populations at a group level did not find evidence of an association between RF-EMF exposure and NSPS. Objectives: We explored the association between exposure to RF-EMF in daily life and the occurrence of NSPS in individual self-declared electro hypersensitive persons using body worn exposimeters and electronic diaries. Methods: We selected seven individuals who attributed their NSPS to RF-EMF exposure. The level of and variability in personal RF-EMF exposure and NSPS were determined during a three-week period. Data were analyzed using timeseries analysis in which exposure as measured and recorded in the diary was correlated with NSPS. Results: We found statistically significant correlations between perceived and actual exposure to wireless internet (WiFi - rate of change and number of peaks above threshold) and base stations for mobile telecommunications (GSM+UMTS downlink, rate of change) and NSPS scores in four of the seven participants. In two persons a higher EMF exposure was associated with higher symptom scores, and in two other persons it was associated with lower scores. Remarkably, we found no significant correlations between NSPS and timeweighted average power density, the most commonly used exposure metric. Conclusions: RF-EMFexposure was associated either positively or negatively with NSP Sinsome but not all of the selected self-declared electro hypersensitive persons. https://doi.org/10.1016/j.envint.2018.08.064

This article provides a description of the emergence of the Spanish ‘Occupy’ movement, Democracia real ya. The aim is to analyse the innovative discursive features of this movement and to connect this analysis to what we consider the innovative potential of the critical sciences. The movement is the result of a spontaneous uprising that appeared on the main squares of Madrid and Barcelona on 15 May 2011 and then spread to other Spanish cities. This date gave it its name: 15M. While the struggle for democracy in Spain is certainly not new, the 15M group shows a series of innovative features. These include the emphasis on peaceful struggle and the imaginary of a new democracy or worldview, transmitted through innovative placards and slogans designed by Spanish citizens. We consider these innovative not only due to their creativity, but also because of their use as a form of civil action. Our argument is that these placards both functioned as a sign of protest and, in combination with the demonstrations and the general dynamics of 15M, helped to reframe the population’s understanding of the crisis and rearticulate the identity of the citizens from victims to agents. In order to analyse the multimodal character of this struggle, we developed an interdisciplinary methodology, which combines socio-cognitive approaches that consider ideological proposals as socio-cognitive constructs (i.e. the notion of narrative or cognitive frame), and Critical Discourse Analysis (CDA) in the analysis of discourses related to processes of social imagination and transformation. The socio-constructivist perspective is used to consider these discourses in relation to their actors, particular contexts and actions. The use of CDA, which included a careful rhetoric analysis, helped to analyse the process of deconstruction, transformation and reconstruction that 15M uses to maintain its struggle. The narrative analysis and the discursive theoretical concept of articulation helped to methodologically show aspects of the process of change alluded to above. This change was both in terms of cognition and in the modification of identity that turned a large part of the Spanish population from victims to indignados and to the neologism indignadanos, which is a composition of indignado and ciudadano (citizen).

Background: For patients with coronary artery disease (CAD), smoking is an important risk factor for the recurrence of a cardiovascular event. Motivational interviewing (MI) may increase the motivation of the smokers to stop smoking. Data on MI for smoking cessation in patients with CAD are limited, and the active ingredients and working mechanisms of MI in smoking cessation are largely unknown. Therefore, this study was designed to explore active ingredients and working mechanisms of MI for smoking cessation in smokers with CAD, shortly after a cardiovascular event. Methods: We conducted a qualitative multiple case study of 24 patients with CAD who participated in a randomized trial on lifestyle change. One hundred and nine audio-recorded MI sessions were coded with a combination of the sequential code for observing process exchanges (SCOPE) and the motivational interviewing skill code (MISC). The analysis of the cases consisted of three phases: single case analysis, cross-case analysis, and cross-case synthesis. In a quantitative sequential analysis, we calculated the transition probabilities between the use of MI techniques by the coaches and the subsequent patient statements concerning smoking cessation. Results: In 12 cases, we observed ingredients that appeared to activate the mechanisms of change. Active ingredients were compositions of behaviors of the coaches (e.g., supporting self-efficacy and supporting autonomy) and patient reactions (e.g., in-depth self-exploration and change talk), interacting over large parts of an MI session. The composition of active ingredients differed among cases, as the patient process and the MI-coaching strategy differed. Particularly, change talk and self-efficacy appeared to stimulate the mechanisms of change “arguing oneself into change” and “increasing self-efficacy/confidence.”

Artikel proefschrift Jos Dobber verschenen in Frontiers in Psychiatry 24 maart 2020: Background: Trials studying Motivational Interviewing (MI) to improve medication adherence in patients with schizophrenia showed mixed results. Moreover, it is unknown which active MI-ingredients are associated with mechanisms of change in patients with schizophrenia. To enhance the effect of MI for patients with schizophrenia, we studied MI's active ingredients and its working mechanisms. Methods: First, based on MI literature, we developed a model of potential active ingredients and mechanisms of change of MI in patients with schizophrenia. We used this model in a qualitative multiple case study to analyze the application of the active ingredients and the occurrence of mechanisms of change. We studied the cases of fourteen patients with schizophrenia who participated in a study on the effect of MI on medication adherence. Second, we used the Generalized Sequential Querier (GSEQ 5.1) to perform a sequential analysis of the MI-conversations aiming to assess the transitional probabilities between therapist use of MI-techniques and subsequent patient reactions in terms of change talk and sustain talk. Results: We found the therapist factor “a trusting relationship and empathy” important to enable sufficient depth in the conversation to allow for the opportunity of triggering mechanisms of change. The most important conversational techniques we observed that shape the hypothesized active ingredients are reflections and questions addressing medication adherent behavior or intentions, which approximately 70% of the time was followed by “patient change talk”. Surprisingly, sequential MI-consistent therapist behavior like “affirmation” and “emphasizing control” was only about 6% of the time followed by patient change talk. If the active ingredients were embedded in more comprehensive MI-strategies they had more impact on the mechanisms of change. Conclusions: Mechanisms of change mostly occurred after an interaction of active ingredients contributed by both therapist and patient. Our model of active ingredients and mechanisms of change enabled us to see “MI at work” in the MI-sessions under study, and this model may help practitioners to shape their MI-strategies to a potentially more effective MI.

Permanent grassland soils can act as a sink for carbon and may therefore positively contribute to climate change mitigation and adaptation. We compared young (5–15 years since latest grassland renewal) with old (>20 years since latest grassland renewal) permanent grassland soils in terms of carbon stock, carbon sequestration, drought tolerance and flood resistance. The research was carried out on marine clay soil at 10 dairy farms with young and old permanent grassland. As hypothesized, the carbon stock was larger in old grassland (62 Mg C ha−1) topsoil (0–10 cm) than in young grassland topsoil (51 Mg C ha−1). The carbon sequestration rate was greater in young (on average 3.0 Mg C ha−1 year−1) compared with old grassland (1.6 Mg C ha−1 year−1) and determined by initial carbon stock. Regarding potential drought tolerance, we found larger soil moisture and soil organic matter (SOM) contents in old compared with young grassland topsoils. As hypothesized, the old grassland soils were more resistant to heavy rainfall as measured by water infiltration rate and macroporosity (at 20 cm depth) in comparison with the young grassland soils. In contrast to our hypothesis we did not find a difference in rooting between young and old permanent grassland, probably due to large variability in root biomass and root tip density. We conclude that old grasslands at dairy farms on clay soil can contribute more to the ecosystem services climate change mitigation and climate change adaptation than young grasslands. This study shows that under real farm conditions on a clay topsoil, carbon stock increases with grassland age and even after 30 years carbon saturation has not been reached. Further study is warranted to determine by how much extending grassland age can contribute to climate change mitigation and adaptation.
