Institutional imperatives versus emergent dynamics: a case study on continuous change in higher education

This qualitative case study examines continuous change in a higher education organization (HEO). Both real time and retrospective data covering a 6-year period of the case were collected. The findings suggest that, in order to meet institutional imperatives the HEO defined several managerial and academic domains when the internationalization process was launched. When organizational members activate these domains they confronted with local needs, problems, and opportunities, which enable them to modify, update or extend the defined domains. In addition, throughout time the members constantly realize the missing parts and incorporate them into the process. These findings suggest several insights on the adaptability of higher education organizations.     

A cross-national comparison of perceived strategic importance of RFID for CIOs in Germany and Italy

Purpose

Drawing from literature on innovation, strategy and culture the objective of this study is to explore the role of perceived potentials and perceived strategic importance on CIOs’ perspective on RFID technology in two different cultural settings.

Methodology

Based on survey responses from 463 German and 157 Italian IT decision makers we analyzed the data with PLS structural equation modeling.

Findings

We show that perceived potentials of RFID influence the perceived strategic importance which positively influences CIOs’ intention to invest in RFID. The composition of perceived potentials affecting the strategic importance of RFID differs significantly in both cultures. In Germany, potentials attributed to RFID are improving quality, automating manpower, reducing counterfeits, and improving customer service. Italian CIOs value reducing stock inconsistencies, optimizing stock keeping, and improving customer service as RFID potentials. Regardless of culture, findings show that company size hardly has impact on perceived strategic importance.

Originality/value

This research shows on a large empirical basis cultural differences in the perception of RFID in two countries using PLS.

Can the inerter be a successful shock-absorber? The case of a ball-screw inerter with a variable thread lead

This paper investigates an application of a ball-screw inerter for mitigation of impact loadings. The problem of impact absorption is to provide a minimum reaction force that optimally decelerates and eventually stops an impacting object within the available absorber stroke. It significantly differs from vibration mitigation problems which are typical application of inerters. The paper demonstrates that the optimum absorption can be achieved by fully passive means. For known values of the object mass and inerter parameters, the obtained solution is independent of the impact velocity. The optimum passive absorption is achieved by employing a variable thread lead. As a result, two force components emerge, the typical inertance-related force and a damping-like term, and sum up to provide the optimum constant deceleration force. This result is relatively unique: conventional absorbers do not provide a constant force even with complex active control systems. Finally, an optimization problem is formulated to reduce the influence of process uncertainties (range of possible mass values, unknown friction). The results are verified and analyzed in a numerical example.     

Improved determination of mechanical power output in rowing: Experimental results

In rowing, mechanical power output is a key parameter for biophysical analyses and performance monitoring and should therefore be measured accurately. It is common practice to estimate on-water power output as the time average of the dot product of the moment of the handle force relative to the oar pin and the oar angular velocity. In a theoretical analysis we have recently shown that this measure differs from the true power output by an amount that equals the mean of the rower’s mass multiplied by the rower’s center of mass acceleration and the velocity of the boat. In this study we investigated the difference between a rower’s power output calculated using the common proxy and the true power output under different rowing conditions. Nine rowers participated in an on-water experiment consisting of 7 trials in a single scull. Stroke rate, technique and forces applied to the oar were varied. On average, rowers’ power output was underestimated with 12.3% when determined using the common proxy. Variations between rowers and rowing conditions were small (SD = 1.1%) and mostly due to differences in stroke rate. To analyze and monitor rowing performance accurately, a correction of the determination of rowers’ on-water power output is therefore required.     

Football practice with youth players in the “Footbonaut”

In today’s leading football training centres, state-of-the-art performance diagnostic systems such as the “Footbonaut” allow controlled and standardized assessments of physical and mental components of agility, e.g. speed of action and ball control, that are considered to be decisive for talent identification and development. However, effects of induced physical and mental strain on performing football-specific practice patterns remain to be elucidated, particularly in youth players, and, thus, characterize the purpose of this study. 33 randomly assigned competitive football players (U14 to U16) performed a standardized Footbonaut practice pattern (i.e. 20 balls randomly drawn at 50?km/h each), prior to and immediately after either mentally demanding tasks (MDT; n?=?11; continuous Vienna Test System’s Stroop task and determination test), physically demanding tasks (PDT; n?=?11; consisted of 4?×?4?min of football-specific high-intensity intervals with 3?min of active recovery in between) or a control condition (CON; n?=?11). Continuous heart rates (HR) as well as self-perceptions of fatigue were assessed. Main findings revealed performances for speed of action (p?=?0.44; f?=?0.01) and ball control (p?=?0.15; f?=?0.03) that were not modulated in the face of induced physical and mental strain as indicated by increased HR following PDT (p?<?0.001; d?>?0.8), or in the face of increased self-perceptions of fatigue following PDT and MDT (both p?<?0.001; both d?>?0.8) compared to CON. This is in line with a suggested talent factor and previous reports on motivational trade-off aspects in youth players. However, the present study’s short-timed practice patterns make it difficult to reliably compare a measuring sensitivity to complex football-specific movement behavioural and technical proficiencies with respect to mental and physical strain of longer-lasting football games and, thus, need further investigation in favour of improving talent identification and development using the Footbonaut.     

Rethinking agency as an assemblage from change management to collaborative work

The movement towards inclusion comes together with a neoliberal audit mentality whereby individuals are held responsible for the transformations. The Special Educational Needs Coordinators (SENCOs) are seen as ‘change agents’ whose task it is, to support teachers in adapting their approach to optimise the chances for children with special needs in regular schools. In this paper, we want to problematise the ‘responsibility-blame discourse’ and look differently at agency. By using a diffractive methodology based on collaborative work, in which we have used material images of the workplace of the SENCO, and read-the-data-while-thinking-with-theory, we deconstruct the individualisation of agency. The SENCOs are no longer seen as separate individual humanist subjects where agency is solely lodged in the body of an individual agent [Barad, K. 2007. Meeting the Universe Halfway: Quantum Physics and the Entanglement of Matter and Meaning. Durham: Duke University Press] but the SENCOs are part of the intra-active entanglement of multiple agencies, of an assemblage. This re-conceptualisation of agency leads to a different approach to inclusion, in which the participants in any encounter can work as part of the assemblage to develop communities capable of re-thinking practice and transforming it into a place where children with special needs become legitimate members of the school.     

More Effective Consolidation of Episodic Long‐Term Memory in Children Than Adults—Unrelated to Sleep

Abilities to encode and remember events in their spatiotemporal context (episodic memory) rely on brain regions that mature late during childhood and are supported by sleep. We compared the temporal dynamics of episodic memory formation and the role of sleep in this process between 62 children (8–12 years) and 57 adults (18–37 years). Subjects recalled “what–where–when” memories after a short 1‐hr retention interval or after a long 10.5‐hr interval containing either nocturnal sleep or daytime wakefulness. Although children showed diminished recall of episodes after 1 hr, possibly resulting from inferior encoding, unlike adults, they showed no further decrease in recall after 10.5 hr. In both age groups, episodic memory benefitted from sleep. However, children's more effective offline retention was unrelated to sleep.     

At school with the avant-garde: European architects and the modernist project in England

‘New people create new buildings, but new buildings also create New people’, so wrote the German art critic Fritz Wichhert in The New Building: Art as Educator in 1928. The social and psychological legacy of the First World War was deeply profound and affected how people thought about the future. Children were seen to symbolise a new and better future and Modernist architects saw their role as helping to build a new society, a society where the design of schools was seen as an agent of social change. The focus of this article is on the role of the avant-garde in this reforming social project and its impact on school design. It is organised into four sections. The first section introduces the terms modernism and avant-garde in relation to (school) architecture, particularly British modernism. The second section focuses in on the experiences of émigré architects in conservative 1930s England, and in particular the support they received from refugee organisations and their treatment by the state as war in Europe became a reality. The third section discusses the role of these architects in the construction of modernist schools in England. In the fourth and final section the impact of émigré architects on modernist schools in England is discussed along with the concepts of transnational history and cultural transfer.     

Developmental Links between Teacher-Child Closeness and Disobedience for Boys Placed in Special Education

The aim of this study was to examine developmental links between disobedience and teacher-child closeness in a sample of boys with psychiatric disorders (i.e., emotional and behavioral disorders (EBD) and autism spectrum disorders (ASD)) and special educational needs who are placed in special education. More specifically, this study examined whether developmental links were different between boys with EBD (n = 150) versus boys with ASD (n = 122). Developmental links between disobedience and teacher-child closeness were investigated by incorporating a multi-informant perspective using teacher, child, and peer ratings and analyzed using autoregressive cross-lagged models across three waves within one school year. Results showed that in general, developmental links between teacher-child closeness and disobedience were stronger for boys with EBD than for boys with ASD. Specifically, boys with EBD experiencing less teacher-child closeness showed more disobedience, which in turn negatively affected their relationship development according to teacher ratings. Surprisingly, for boys with ASD, higher levels of disobedience predicted higher levels of teacher-rated teacher-child closeness during the school year. Our results offer more insight into the differential impact of teacher-child closeness on the behavioral problems for children with EBD and ASD.
