    Feedback on Library and Learning Resources (LLR) services and support at the University of the Arts London (UAL) is received from a very extensive range of sources. However, although a considerable quantity of information is available for analysis, it remains very difficult for LLR staff to extract meaningful data from these numerous sources, which can reveal, in depth, the true, individual student experience of LLR services. LLR is aware that there is a lot that is not known, or is not being asked of our students, about their individual experience, which could prove extremely helpful for effective decision-making and service design and delivery. In particular, LLR is interested in identifying and resolving issues of access and support for students currently studying at UAL who are from under represented groups in higher education. Make the numbers counts has enabled the Fellowship Team to move beyond looking at usage figures, gate counts, numbers of issue and renewal transactions, borrower numbers and percentage satisfaction levels, and to extend and add to our knowledge-base of what students at UAL really think and feel about academic libraries. It has enabled us to explore how individual students make use of the services and support provided by LLR. The qualitative data collected through this project has been compared to existing sources of information and to staff experience and understanding of the issues raised, to see if the findings of our research challenge or correlate with other evidence which relates to LLR use and non-use. The focus of the Fellowship has been to explore the particular experience of students who are the first in their family to go to university and who are currently studying at Camberwell, Chelsea and Wimbledon (CCW) and the London College of Communication. Research has shown that this group of students is important amongst the range of students who are now entering higher education through the expansion of participation in university and tertiary-level study. Talking to first generation students was a key element of the project and the greatest source of learning for the Project Team

    The main goal of this article is to describe the investigation conducted in themasters’ thesis project: Digital Medellín – communities of practice and informationand communication technology for organizational development. This is done by givinga description of the background, problem area, the method and theories suchas ethnography, a socio-cultural perspective and the concept of communitiesof practice. Two case studies are presented and discussed. The findings of theresearch are stated in the form of three principal conclusions

    Structural Comparison between Sucrose and Trehalose in Aqueous Solution

    The two sugar molecules sucrose and trehalose are both considered as stabilizing molecules for the purpose of preserving biological materials during, for example, lyophilization or cryo-preservation. Although these molecules share a similar molecular structure, there are several important differences in their properties when they interact with water, such as differences in solubility, viscosity, and glass transition temperature. In general, trehalose has been shown to be more efficient than other sugar molecules in preserving different biological molecules against stress, and thus by investigating how these two disaccharides differ in their water interaction, it is possible to further understand what makes trehalose special in its stabilizing properties. For this purpose, the structure of aqueous solutions of these disaccharides was studied by using neutron and X-ray diffraction in combination with empirical potential structure refinement (EPSR) modeling. The results show that there are surprisingly few differences in the overall structure of the solutions, although there are indications for that trehalose perturbs the water structure slightly more than sucrose

    Is it all about culture? A study on frustration with respect to the work situation in dispersed, global IT projects at a merged, multinational company

    This article reports on the difficulties, peculiar to dispersed global projects, which may be a source of frustration to project members. Our study was carried out within a multinational pharmaceutical company, which following a merger reorganized its IT organization into global organisation. Members of the Swedish part of its IT organization reported severe problems after the reorganization, and called for an investigation. The reported problems were global projects struggling with cultural differences and, as a consequence, overconsuming their allotted resources. However, previous research regarding merged organizations has found, that complaints about cultural differences might be a mask for other problems. Our findings do include cultural differences being an obstacle to project performance. However, we identified project complexity and geographical distance as two additional, important factors explaining frustration and low performance in the global, dispersed projects. Thus, our study supports the earlier theory that practitioners overload the concept cultural differences, ignoring that global projects typically involve more stakeholders, and that it is more challenging to create the trust among the dispersed team members necessary to create a high-performing team. Global projects can be expected to reach a climate of high-performing team later than a local project, leaving its members to performing less during a longer time. Consequently, and putting other advantages aside, if management fail to develop a successful global team strategy, such projects can be expected to be more costly to the company, and more frustrating to team members being used to quickly reaching a high-performing state. Such a strategy would need to include ways of motivating project members to actively build trustful relations

    Stabilization of proteins embedded in sugars and water as studied by dielectric spectroscopy

    In many products proteins have become an important component, and the long-term properties of these products are directly dependent on the stability of their proteins. To enhance this stability it has become common to add disaccharides in general, and trehalose in particular. However, the mechanisms by which disaccharides stabilize proteins and other biological materials are still not fully understood, and therefore we have here used broadband dielectric spectroscopy to investigate the stabilizing effect of the disaccharides trehalose and sucrose on myoglobin, with the aim to enhance this understanding in general and to obtain specific insights into why trehalose exhibits extraordinary stabilizing properties. The results show the existence of three or four clearly observed relaxation processes, where the three common relaxations are the local (ÎČ) water relaxation below the glass transition temperature (Tg), the structuralα-relaxation of the solvent, observed aboveTg, and an even slower protein relaxation due to large-scale conformational protein motions. For the trehalose containing samples with less than 50 wt% myoglobin a fourth relaxation process was observed due to a ÎČ-relaxation of trehalose belowTg. This latter process, which was assigned to intramolecular rotations of the monosaccharide rings in trehalose, could not be detected for high protein concentrations or for the sucrose containing samples. Since sucrose has previously been found to form more intramolecular hydrogen bonds at the present hydration levels, it is likely that this rotation becomes too slow to be observed in the case of sucrose. However, this sugar relaxation has probably less influence on the protein stability belowTg, where the better stabilizing effect of trehalose on proteins can be explained by our observation that trehalose slows down the water relaxation more than sucrose does. Finally, we show that the α-relaxation of the solvent and the large-scale protein motions exhibit similar temperature dependences, which suggests that these protein motions are slaved by the α-relaxation. Furthermore, the α-relaxation of the trehalose solution is slower than for the corresponding sucrose solution, and thereby also the protein motions become slower in the trehalose solution, which explains the more efficient stabilizing effect of trehalose on proteins aboveT
