description: Ring polymers remain a major challenge to our current understanding of polymer dynamics. Experimental results are difficult to interpret because of the uncertainty in the purity and dispersity of the sample. Using both equilibrium and non-equilibrium molecular dynamics simulations we have systematically investigated the structure, dynamics and rheology of perfectly controlled ring/linear polymer blends with chains of such length and flexibility that the number of entanglements is up to about 14 per chain, which is comparable to experimental systems examined in the literature. The smallest concentration at which linear contaminants increase the zero-shear viscosity of a ring polymer melt of these chain lengths by 10% is approximately one-fifth of their overlap concentration. When the two architectures are present in equal amounts the viscosity of the blend is approximately twice as large as that of the pure linear melt. At this concentration the diffusion coefficient of the rings is found to decrease dramatically, while the static and dynamic properties of the linear polymers are mostly unaffected. Our results are supported by a primitive path analysis.

It is too hot in here! A performance, energy and heat aware scheduler for Asymmetric multiprocessing processors in embedded systems.
Creators: name: Wolff, Willy
Publisher: name: Lancaster University
Year: 2023

description: Modern architecture present in self-power devices such as mobiles or tablet computers proposes the use of asymmetric processors that allow either energy-efficient or performant computation on the same SoC. For energy efficiency and performance consideration, the asymmetry resides in differences in CPU micro-architecture design and results in diverging raw computing capability. Other components such as the processor memory subsystem also show differences resulting in different memory transaction timing. Moreover, based on a bus-snoop protocol, cache coherency between processors comes with a peculiarity in memory latency depending on the processors operating frequencies. All these differences come with challenging decisions on both application schedulability and processor operating frequencies. In addition, because of the small form factor of such embedded systems, these devices generally cannot afford active cooling systems. Therefore thermal mitigation relies on dynamic software solutions. Current operating systems for embedded systems such as Linux or Android do not consider all these particularities. As such, they often fail to satisfy user expectations of a powerful device with long battery life. To remedy this situation, this thesis proposes a unified approach to deliver high-performance and energy-efficiency computation in each of its flavours, considering the memory subsystem and all computation units available in the system. Performance is maximized even when the device is under heavy thermal constraints. The proposed unified solution is based on accurate models targeting both performance and thermal behaviour and resides at the operating systems kernel level to manage all running applications in a global manner. Particularly, the performance model considers both the computation part and also the memory subsystem of symmetric or asymmetric processors present in embedded devices. The thermal model relies on the accurate physical thermal properties of the device. Using these models, application schedulability and processor frequency scaling decisions to either maximize performance or energy efficiency within a thermal budget are extensively studied. To cover a large range of application behaviour, both models are built and designed using a generative workload that considers fine-grain details of the underlying microarchitecture of the SoC. Therefore, this approach can be derived and applied to multiple devices with little effort. Extended evaluation on real-world benchmarks for high performance and general computing, as well as common applications targeting the mobile and tablet market, show the accuracy and completeness of models used in this unified approach to deliver high performance and energy efficiency under high thermal constraints for embedded devices.

description: Ibata et al. reported evidence for density and kinematic cusps in the Galactic globular cluster M54, possibly due to the presence of a 9400 solar-mass black hole. Radiative signatures of accretion onto M54's candidate intermediate-mass black hole (IMBH) could bolster the case for its existence. Analysis of new Chandra and recent Hubble Space Telescope astrometry rules out the X-ray counterpart to the candidate IMBH suggested by Ibata et al. If an IMBH exists in M54, then it has an Eddington ratio of L(0.3-8 keV) / L(Edd) < 1.4 x 10^(-10), more similar to that of the candidate IMBH in M15 than that in G1. From new imaging with the NRAO Very Large Array, the luminosity of the candidate IMBH is L(8.5 GHz) < 3.6 x 10^29 ergs/s (3 sigma). Two background active galaxies discovered toward M54 could serve as probes of its intracluster medium.

Investment Volatility: A Critique of Standard Beta Estimation and a Simple Way Forward

description: Beta is a widely used quantity in investment analysis. We review the common interpretations that are applied to beta in finance and show that the standard method of estimation - least squares regression - is inconsistent with these interpretations. We present the case for an alternative beta estimator which is more appropriate, as well as being easier to understand and to calculate. Unlike regression, the line fit we propose treats both variables in the same way. Remarkably, it provides a slope that is precisely the ratio of the volatility of the investment's rate of return to the volatility of the market index rate of return (or the equivalent excess rates of returns). Hence, this line fitting method gives an alternative beta, which corresponds exactly to the relative volatility of an investment - which is one of the usual interpretations attached to beta.

description: We study the historical process that led to the worldwide adoption, throughout mathematical research papers and textbooks, of the denomination "Vandermonde determinant". The mathematical object can be related to two passages in Vandermonde's writings, of which one inspired Cauchy's definition of determinants. Influential citations of Cauchy and Jacobi may have initiated the naming process. It started during the second half of the 19\textsuperscript{th} century as a pedagogical practice in France. The spread in textbooks and research journals began during the first half of 20\textsuperscript{th} century, and only reached full acceptance after the 1960's. The naming process is still ongoing, in the sense that the volume of publications using the denomination grows significantly faster than the overall volume of the field.

description: The scattering parameter extraction method of metamaterial homogenization is reviewed to show that the only ambiguity is the one related to the choice of the branch of the complex logarithmic function (or the complex inverse cosine function), whereas it has no ambiguity for the sign of the wave number and intrinsic impedance. While the method indeed yields two signs of the intrinsic impedance, and thus the wave number, the signs are dependent, and moreover, both sign combinations lead to the same permittivity and permeability, and are thus permissible. This observation is in distinct contrast to a number of statements in the literature where the correct sign of the intrinsic impedance and wave number, resulting from the scattering parameter method, is chosen by imposing additional physical requirements such as passivity. The scattering parameter method is reviewed through an investigation of a uniform plane wave normally incident on a planar slab in free-space, and the severity of the branch ambiguity is illustrated through simulations of a known metamaterial realization. Several approaches for proper branch selection are reviewed and their suitability to metamaterial samples is discussed.

Factors influencing the fluid flow and heat transfer in electron beam melting of Ti-6Al-4V
Creators: name: Meng, Tao
Publisher: name: University of British Columbia
Year: 2009

description: Electron Beam Cold Hearth Remelting (EBCHR) and its associated casting process is an important consolidation technique for the treatment of virgin titanium sponge and scrap. The development of robust models to describe the casting process hinge on accurately capturing heat transfer phenomena within the ingot and fluid flow phenomena within the liquid pool. The flow field that develops within the liquid pool is influenced by several factors including buoyancy driven flow due to thermal gradients within the pool, surface tension, or Marangoni, driven flow due to the large thermal gradients induced on the surface by the Electron Beam and the ability of the mushy, or semi-solid, zone to attenuate the flow. A mathematical model describing fluid flow and heat transfer in a Ti6Al4V button sample during electron beam melting has been developed to examine the relative contribution of the three factors cited above on the pool profile and flow field within the pool. The model has also been used to compare the steady state solution for a time averaged circular beam pattern with a transient solution obtained for the case where the beam pattern is comprised of a series of discrete points scribing the same circle. The latter, in which the beam spot is periodically stationary for small but finite periods, is intended to more closely mimic the industrial process. The model is also used to examine the sensitivity of the predictions to changes in numerical and process parameters. The results indicate that the electron beam power and heat transfer coefficient have the largest influence on the liquid pool profile while the surface tension coefficient has little effect (i.e. 25% change in electron beam power results in ~25% liquid pool profile while 100% change in time step results in less than 1% in prediction).

Cultural-Historical Activity Theory (CHAT)

description: Abstract: All over the world, there is a tendency for a child to study mathematics at an increasingly young age. However, in all studies of this issue, the mathematical development of a preschooler is understood as the assimilation of the ordering of numbers and their operations. Research conducted in line with the CHAT revealed the possibility of forming a different, more reasonable idea of numbers; as a means of measuring quantities. This raises the question of the prerequisites and conditions for its development in older preschool children. The purpose of our study was to investigate the conditions for introducing the idea of numbers as a means of measuring quantities to older preschool children, taking into account specific requirements of this age group. We created four programs aimed at the formation of this basic mathematical concept (20 classes, 20 minutes each). They were similar with regards to representation and the actions performed by the children but differed by teaching method (visual example in two cases, model, and symbol). A diagnostic toolkit also was developed. This was aimed at the assessment of the levels of development in the understanding of the mathematical concept. Approbation was performed on a sample of 60 6–7-year-old preschoolers (mean age 6.4). The main outcome was that the type of training didn’t play a major role as long as the process was organized in an age-appropriate fashion. The mathematical skills of the participants improved with all four programs using all methods.
Identification and characterization of CIS-acting regulatory elements for human x-inactive specific transcript
Creators: name: Chang, Chia-Yu
Publisher: name: University of British Columbia
Year: 2009

description: Dosage compensation in female mammals is achieved by XIST/Xist RNA mediated transcriptional silencing of one of the two X chromosomes. Several developmental specific cis-acting regulatory elements for mouse XIST have been demonstrated. One of these regulatory elements is the mouse Tsix locus, which is transcribed antisense to Xist and represses Xist on one of the X chromosomes at the onset of X inactivation. A transcript antisense to human XIST has been shown; however, its functional significance has been repeatedly challenged. My thesis aims to uncover cis-acting regulatory elements for human XIST and determine whether the elements are comparable to those found in mice. Currently, multi-copy integrations of a transgene containing human XIST into male mouse embryonic stem (ES) cells or into male human fibrosarcoma cells are the model systems of choice for studying the initiation of human X inactivation because the transcription antisense to human XIST can be detected by RT-PCR from the transgenes. Using DNase I hypersensitivity (HS) mapping, I found one HS site on the human transgene in mouse ES cells located approximately 11 kb downstream of XIST3’ end. While this HS site does not correspond to the transcription starts of TSIX previously described, it encompasses a small cluster of CTCF binding sites based on in silico search. Besides the downstream HS site, I discovered two HS sites in differentiated cell lines. One of the HS sites is immediately upstream of the XlST transcription start site. The other HS site (HS 101), located approximately 65 kb upstream of human XIST transcription start, resides within a region that shares above 70% sequence identity with cow and dog but not mouse. I analyzed these upstream HS sites and found that HS 101 exhibits bi-directional promoter and enhancer activity. My thesis revealed three previously unidentified HS sites flanking the human XIST locus; the presence of only one ES cell specific HS site downstream of XIST3’ end is in sharp contrast to the seven sites reported in mouse. The results suggest that mouse Xist and human XIST are regulated differently. To account for the differences in regulatory elements, I propose an alternative model for human XIST regulation.

Daily stress and health symptoms : The mediating and moderating roles of biopsychosocial factors
Creators: name: Hanson, Margaret D.
Publisher: name: University of British Columbia
Year: 2009

description: Psychological stress has been cited as a risk factor for poor health across the lifespan, in many cultures, and in both the human and animal literatures. In this program of research we tested potential psychological and biological mediators linking daily stressful life experiences to daily health symptoms. Namely, we tested whether the psychological factors of coping or emotional responses to stress, as well as biological responses of daily cortisol or sleep, mediated the daily stress-health association. A second goal of this research was to test whether stress-biology associations varied according to the individuals’ childhood psychosocial environment. 87 healthy undergraduate students (Mage=21.51, 66.7% female, 27.6% Caucasian) participated in the study. Participants provided information on characteristics of their childhood family environment (conflict, parental warmth). For one week they completed a daily stress checklist via electronic diary, and noted their coping and emotional responses to the most serious stressor of their day. As well, they provided salivary cortisol samples 4 times/day, and wore an Actiwatch to measure sleep (minutes, efficiency). Using hierarchical linear modeling techniques, we found that, on days when individuals reported more severe stressors, they also reported more health symptoms (β = .24, p =.04). Emotional responses to stress significantly mediated the relation between daily stress and daily health symptoms, such that when emotional responses to stress were controlled, the relationship between daily stress and health symptoms became non-significant (β = -.001, p =.99). In contrast, coping and biological profiles did not mediate the daily stress-health relationship. Furthermore, some evidence emerged that the childhood psychosocial environment moderated the relationship between daily stress and biological outcomes; among individuals from risky childhood environments, on days when they experienced a greater number of stressors, they slept for fewer minutes (β =-12.10, p=.02). As well, individuals from childhoods characterized as low in parental warmth, on days when they experienced more severe daily stressors, they had greater daily cortisol output (β =-0.16, p=.04). Overall, findings suggest that individuals may be more susceptible to the negative effects of stress on health if they are from difficult childhood environments and have negative emotional responses to stressors.

description: There is growing evidence that the flow of driven amorphous solids is not homogeneous, even if the macroscopic stress is constant across the system. Via event driven molecular dynamics simulations of a hard sphere glass, we provide the first direct evidence for a correlation between the fluctuations of the local volume-fraction and the fluctuations of the local shear rate. Higher shear rates do preferentially occur at regions of lower density and vice versa. The temporal behavior of fluctuations is governed by a characteristic time scale, which, when measured in units of strain, is independent of shear rate in the investigated range. Interestingly, the correlation volume is also roughly constant for the same range of shear rates. A possible connection between these two observations is discussed.

description: Abstract: One of the priority areas of child and adolescent clinical psychology is the prevention of deviant behavior. In the conditions of the digitalization of society, deviant behavior of a teenager is the result of a complex interaction of various factors. These factors are often defects in school and family education, revealing the unfavorable features of his immediate environment in the family. The purpose of the work: to determine the psychological characteristics, emotional state, and suicidal risk of adolescents in the conditions of the digitalization of society. Research methods. Questionnaire of suicide risk. Pathocharacterological diagnostic questionnaire (PDO) for adolescents A.E. Lichko (1970). Questionnaire of suicidal risk by A.G. Shmelev, modified by T.N. Razuvaeva. Methodology for diagnosing socio-psychological adaptation by K. Rogers and R. Diamond. Sample: 50 adolescents from secondary school No. 37 in Samara, aged 14 to 16 years (29 boys and 21 girls). The main results of the study. Adolescents with a high suicidal risk had high rates of affectivity, failure, social pessimism, breaking down cultural barriers, maximalism, and negative time perspective. Characteristics such as labile, psychasthenic and sensitive prevailed. Adolescents were dominated by a negative attitude towards the past (rS= 0.644*), towards themselves (rS= 0.696*) and towards superior persons (rS= 0.774**). Values of sincerity were also at a low level (rS= 0.698*). In the conditions of the digitalization of society, the prevention of suicidal risk is aimed at early diagnosis and screening of socio-psychological factors of significance. The mathematical regression model revealed: SR = 3.952 + (0.593*D) + (0.585*SP) + (0.391*M) (0.179*C) + (1.087*IS) (0.096*A) + (1.517*НВС), for demonstrativeness, pessimism, maximalism, sensitive type of accentuation. Currently, the behavior of a teenager is the result of a complex interaction of socio-psychological factors. The digital socialization of a teenager plays a significant role as it facilitates interactions with a combination of factors that impede social and psychological adaptation. Psychotherapeutic work with adolescents is a complex undertaking that requires specialist knowledge and skills in the field of clinical and psychological diagnostics and individual, group, and family psychotherapy.

description: Spin transport in magnetic tunnel junctions comprising a single magnetic layer in the presence of interfacial spin-orbit interaction (SOI) is investigated theoretically. Due to the presence of interfacial SOI, a current-driven spin torque can be generated at the second order in SOI, even in the absence of an external spin polarizer. This torque possesses two components, in-plane and perpendicular to the plane of rotation, that can induce either current-driven {\em magnetization switching} from in-plane to out-of-plane configuration or {\em magnetization precessions}, similarly to Spin Transfer Torque in spin-valves. Consequently, it appears that it is possible to control the magnetization steady state and dynamics by either varying the bias voltage or electrically modifying the SOI at the interface.

description: Abstract: The paper aims to present a theoretical reference framework to support the actions of the sectoral project (Ministry of Education in Cuba) entitled “Promotion of an audiovisual culture for children and families in early childhood”. The theoretical reference framework is structured in relation to the three dimensions determined by Gallego (2018) from a dialectical materialist position: contextual, conceptual, and methodological history. Early childhood is recognized as an indispensable stage for the appropriation of culture, which is an essential factor for development. From this perspective, such appropriation must be conceived not as a process in which the child is a mere recipient, but as an active process in which their participation is essential. In this way, they will not only interact with material and cultural objects, but be immersed in a process of active interrelation with the subjects, adults, and contemporaries that surround them. This study defends the idea that audiovisual consumption should be recognized as an activity that influences the psychological development of children in early childhood, hence forming part of the Social Situation of Development of most Cuban children. It is important to point out that this activity will stimulate development when there is a mediation process (either direct or indirect) between the child and multiple screens, as well as between the child and the audiovisual.

description: We analyze a class of supersymmetric SO(10) grand unified theories with type II seesaw for neutrino masses, where the contribution to PMNS matrix from the neutrino sector has an exact tri-bi-maximal (TBM) form, dictated by a broken S_4 symmetry. The Higgs fields that determine the fermion masses are two 10 fields and one 126 field, with the latter simultaneously contributing to neutrino as well as charged fermion masses. Fitting charged fermion masses and the CKM mixings lead to corrections to the TBM mixing that determine the final PMNS matrix with the predictions theta_{13} ~ 4-6 degrees and the Dirac CP phase to be between -10 and +15 degrees. We also show correlations between various mixing angles which can be used to test the model.

description: Abstract: Proportionality is a topic for research on the formation of concepts and misconceptions. It is both an interesting and challenging domain, especially for studies concerning the transition period between primary and secondary education. The complexity of the concept stems from the contradictions of changing values within the proportion, and changes to the proportion itself, which cannot be performed directly. Our aim is to reconstruct the origin of the proportionality concept as we design an appropriate computerized scaffold for the initial step of the concept's acquisition. The "Make it float!" simulation introduces students to a special digital space: the "shipyard" with water of different salinity, which allows testing of ships that students combine from sinking and floating units. The simulation challenges students to accommodate their actions to control the state of the object under construction. Coordination of the magnitudes' transformations, which focuses on the preservation of buoyancy, leads to comprehension of proportionality between heterogeneous magnitudes of interest (such as mass and volume). Both partners that share the control over the ship's construction must suggest the exact way to coordinate their efforts, as there is no way for them to achieve the desired result individually. Our pilot teaching experiments were carried out with groups of students (8-12 years old). They proved this approach to be effective for the acquisition of the proportionality concept through the meaningful coordination of joint actions. Analysis of students' progress within the designed computer-supported 17 educational module allowed us to outline feasible ways to include digital methods to the learning process.

description: Abstract: This report analyzes the risk of decreasing physical and mental health of adolescents. The research situation in which the rapid development of technologies outpaces the research protocol and methods of psychological diagnostics being developed by scientists to study an objective picture of adolescents' functioning and development in the digital environment are discussed. Assessing the negative effects of the impact of the digital environment on the developing personality requires a particular set of research tasks. Internet overuse refers to excessive time spent online at the expense of other things. Such a behavioral addiction, according to DSM-5, is currently considered a direct threat to the psychological wellbeing of adolescents. PsychoDiagnostic Tools and/or scales traditionally used for diagnostics of various aspects of internet addiction were employed. We used 15 internet addiction tests as empirical material for an overview of the typical criteria of internet addiction. An analysis of the PsychoDiagnostic tools shows the criteria most likely to pose a threat to mental and physical health. The symptoms of internet addiction are: 1) social isolation; 2) emotional problems (depression, anxiety, irritability, etc.); 3) depression / apathy; 4) lack of self-regulation; 5) loss of control over their own behavior. The study results can help create a heuristic model for the study of internet addiction among adolescents, taking into account the research tasks, age of respondents, environmental and individual psychological factors. The pragmatic significance of the results is the possibility of their applicaiton in the design of psychological programs to address teen internet use.

description: Meaning in life is a summative cognition of valuable goals, life purpose, and relationships with things and people. A central feature of meaning in life is the broad consideration of something beyon or more than oneself. We extend this logic to suggest that people with higher in meaning in life will engage in more prosocial behaviors than others. Further extension of this idea led to the longitudinal testing of the hypothesis that one of the important yet overlooked mechanisms that mediate the association between life meaning and prosocial behavior among university students is psychological capital (PsyCap). A total of 913 Chinese university students (25.6% males; 70.3% females; Mage = 19.63, SDage 3 = 1.04) completed a Meaning in Life Questionnaire (MLQ), a Prosocial Tendencies Measure (PTM), and a Positive Psychological Capital Questionnaire (PPQ) at three different times. The results showed that the association between T1 meaning in life and T3 prosocial behavior was significant before adding the mediator variables into the model (β = 0.10, p < 0.001). T2 PsyCap significantly mediated the influence of T1 meaning in life on T3 prosocial behavior (indirect effect = 0.10; 95% CI [0.06, 0.14]). We concluded that meaning in life in university students can influence subsequent prosocial behaviors, both directly and through PsyCap.

description: On the basis of observations of solar granulation obtained with the New Solar Telescope (NST) of Big Bear Solar Observatory, we explored proper motion of bright points (BPs) in a quiet sun area, a coronal hole, and an active region plage. We automatically detected and traced bright points (BPs) and derived their mean-squared displacements as a function of time (starting from the appearance of each BP) for all available time intervals. In all three magnetic environments, we found the presence of a super-diffusion regime, which is the most pronounced inside the time interval of 10-300 seconds. Super-diffusion, measured via the spectral index, $γ$, which is the slope of the mean-squared displacement spectrum, increases from the plage area ($γ=1.48$) to the quiet sun area ($γ=1.53$) to the coronal hole ($γ=1.67$). We also found that the coefficient of turbulent diffusion changes in direct proportion to both temporal and spatial scales. For the minimum spatial scale (22 km) and minimum time scale (10 sec), it is 22 and 19 km$^{2}$ s$^{-1}$ for the coronal hole and the quiet sun area, respectively, whereas for the plage area it is about 12 km$^{2}$ s$^{-1}$ for the minimum time scale of 15 seconds. We applied our BP tracking code to 3D MHD model data of solar convection (Stein et al. 2007) and found the super-diffusion with $γ=1.45$. An expression for the turbulent diffusion coefficient as a function of scales and $γ$ is obtained.

Better Than Their Reputation? On the Reliability of Relevance Assessments with Students

description: During the last three years we conducted several information retrieval evaluation series with more than 180 LIS students who made relevance assessments on the outcomes of three specific retrieval services. In this study we do not focus on the retrieval performance of our system but on the relevance assessments and the inter-assessor reliability. To quantify the agreement we apply Fleiss' Kappa and Krippendorff's Alpha. When we compare these two statistical measures on average Kappa values were 0.37 and Alpha values 0.15. We use the two agreement measures to drop too unreliable assessments from our data set. When computing the differences between the unfiltered and the filtered data set we see a root mean square error between 0.02 and 0.12. We see this as a clear indicator that disagreement affects the reliability of retrieval evaluations. We suggest not to work with unfiltered results or to clearly document the disagreement rates.

description: Abstract: The contemporary epoch is often called a digital age. The perception of this epoch and of its opportunities differs between the generation of psychotherapists (in the research literature they are often referred to as “digital emigrants”) and today’s children (who may be called “digital autochthones”). In the digital age, communication forms and language have undergone transformations, causing changes in the development of children and adolescents. In this new situation, one needs to understand a) how the digital culture influences the development of self-awareness and sense of self in adolescents, and b) which restrictions should be implemented on the usage of smartphones (and other gadgets) during the individual psychotherapy sessions and which of their psychological functions can contribute to the psychotherapeutical process. The paper, thus, discusses whether the usage of a smartphone could become productive for therapy and open a window into the inner world of an adolescent. Based on the cases from the psychotherapeutical practice and using the methodology of functional-structural analysis of psychotherapy (Burlakova, 1996), the paper describes and analyzes both negative functions of usage of smartphones during psychotherapy sessions (resistance; attempts to avoid living through uncomfortable or difficult relations with themselves and/or others, etc.) and positive ones (a means to understand disorders in evolvement of self, compensation of vulnerability, search for new forms of recognition, etc.). The discussed functions provide a basis for reevaluation of this practice and demonstrate potential new opportunities.
Die Explikation beruflichen Wissens in Know-how-Landkarten: Eine empirische Untersuchung mit Anwendern in einem Pilotprojekt

description: Die folgende Untersuchung geht von der Annahme aus, dass Wissensmanagement (WM) in Organisationen eine individuelle Interventionsebene benötigt. Die technischen Voraussetzungen zur Realisierung von WM-Lösungen sind auf der Basis von Datenbank- und Intranet-Technologien weitgehend gegeben. Dass diese Möglichkeiten im Alltag bisher nicht ausreichend genutzt werden, mag daran liegen, dass soziale, organisationale und individuelle Voraussetzungen nicht gleichwertig beachtet und gestaltet werden. Dabei wird regelmäßig darauf verwiesen, dass ohne eine aktive Beteiligung der Mitarbeiter kein WM-Projekt funktionieren kann (Sveiby 1997; Schüppel 1996; Schneider 1996). Die personale Ebene des Themas wird bisher programmatisch in einer veränderten Situation der Beschäftigten bei abnehmender Arbeitsplatzsicherheit gesehen. Beschäftigte sollten demnach ihr Wissen entwickeln, um ihre Beschäftigungsfähigkeit auch über das aktuelle Arbeitsverhältnis hinaus zu erhalten (von Krogh & Venzin 1997; Willke 2000). Eine operationale Umsetzung findet diese Position in Ansätzen, die persönliche Arbeitstechniken und individuelle Arbeitsorganisation, insbesondere den Umgang mit Informationen, auf individueller Ebene verbessern wollen (Reinmann-Rothmeier & Mandl 2000). Da Beschäftigte jedoch Teil einer sozialen Praxisgemeinschaft im organisatorischen Gesamtgefüge sind, reicht die Anpassung individueller Leistungsfähigkeit oder Leistungsbereitschaft an veränderte ökonomische und organisatorische Rahmenbedingungen für ein lebendiges WM nicht aus. Es gilt, das Verhältnis zwischen Individuum und Organisation mit zu reflektieren, wenn der Umgang mit Wissen in Organisationen systematisch gemanagt werden soll (Wehner & Dick 2001). Anders ausgedrückt: Wenn Wissen die entscheidende Ressource zukünftigen Wirtschaftens ist, dann muss der Wandel zur Wissensorganisation von den Beschäftigten nicht nur nachvollzogen sondern auch mitgestaltet werden. Ein Pilotprojekt in einem Industrieunternehmen, das genau diesen Anspruch verfolgte, gab uns die Gelegenheit, die Haltung, das Problembewusstsein und die Vorschläge der Mitarbeiter zu WM von Beginn an bis zur Realisierung eines ersten Tools (Yellow Pages) begleitend zu erforschen. Dieser Beitrag dokumentiert eine der begleitenden Untersuchungen, in der es darum ging, die Mitarbeiter bei der Codierung ihres Wissens und dem Ausfüllen vorbereiteter Dateneingabemasken zu unterstützen.
