Changing with the time: New ventures’ quest for innovation
New ventures are often based on new ideas and innovation. For creating and improving the innovation new ventures can draw on internal and external resources, to which they often have limited access. Our study analyses how new ventures can improve their innovation search by entering collaborative workspaces, so-called co-working spaces. In our qualitative study, we use participative observation and analyze 8 cases of new ventures operating in a coworking-space. Key findings are that forms of innovation search differ with respect to the venture’s life cycle. The new ventures search focus alternates between internal and external search, depending on the current stage of the venture. In general, the co-location of ventures in collaborative workspaces offers rich opportunities for social interactions, information exchange, and collaboration which are especially important for early-stage ventures

Office design and health: a systematic review
Aim: To carry out a systematic review of recent research into the effects of workplace design, comparing individual with shared workspaces, on the health of employees.
Methods: The research question was "Does workplace design (specifically individual offices compared with shared workspaces) affect the health of workers?" A literature search limited to articles published between 2000 and 2017 was undertaken. A systematic review was carried out, and the findings of the reviewed studies grouped into themes according to the primary outcomes measured in the studies.
Results: The literature search identified 15 relevant studies addressing health effects of shared or open-plan offices compared with individual offices. Our systematic review found that, compared with individual offices, shared or open-plan office space is not beneficial to employees' health, with consistent findings of deleterious effects on staff health, wellbeing and productivity. Our findings are also consistent with those of earlier reviews.
Conclusion: These findings have public health implications for the New Zealand workforce. Decisions about workplace design should include weighing the short-term financial benefits of open-plan or shared workspaces against the significant harms, including increased sickness absence, lower job satisfaction and productivity, and possible threats to recruitment and retention of staff
Space-Time Trade-offs for Stack-Based Algorithms
In memory-constrained algorithms we have read-only access to the input, and
the number of additional variables is limited. In this paper we introduce the
compressed stack technique, a method that allows to transform algorithms whose
space bottleneck is a stack into memory-constrained algorithms. Given an
algorithm \alg\ that runs in O(n) time using variables, we can
modify it so that it runs in time using a workspace of O(s)
variables (for any ) or time using variables (for any ). We also show how the technique
can be applied to solve various geometric problems, namely computing the convex
hull of a simple polygon, a triangulation of a monotone polygon, the shortest
path between two points inside a monotone polygon, 1-dimensional pyramid
approximation of a 1-dimensional vector, and the visibility profile of a point
inside a simple polygon. Our approach exceeds or matches the best-known results
for these problems in constant-workspace models (when they exist), and gives
the first trade-off between the size of the workspace and running time. To the
best of our knowledge, this is the first general framework for obtaining
memory-constrained algorithms
Developing front-end Web 2.0 technologies to access services, content and things in the future Internet
The future Internet is expected to be composed of a mesh of interoperable web services accessible from all over the web. This approach has not yet caught on since global user?service interaction is still an open issue. This paper states one vision with regard to next-generation front-end Web 2.0 technology that will enable integrated access to services, contents and things in the future Internet. In this paper, we illustrate how front-ends that wrap traditional services and resources can be tailored to the needs of end users, converting end users into prosumers (creators and consumers of service-based applications). To do this, we propose an architecture that end users without programming skills can use to create front-ends, consult catalogues of resources tailored to their needs, easily integrate and coordinate front-ends and create composite applications to orchestrate services in their back-end. The paper includes a case study illustrating that current user-centred web development tools are at a very early stage of evolution. We provide statistical data on how the proposed architecture improves these tools. This paper is based on research conducted by the Service Front End (SFE) Open Alliance initiative
Mirror, Mirror, On The Wall: Collaborative Screen-Mirroring for Small Groups
Screen mirroring has been available to consumers for some time, however if every mobile device in the room supports screen mirroring to the main display (e.g. a shared TV), this necessitates a mechanism for managing its use. As such, this paper investigates allowing users in small intimacy groups (friends, family etc.) to self-manage mirrored use of the display, through passing/taking/requesting the display from whomever is currently mirroring to it. We examine the collaborative benefits this scheme could provide for the home, compared to existing multi-device use and existing screen mirroring implementations. Results indicate shared screen mirroring improves perceived collaboration, decreases dominance, preserves independence and has a positive effect on a group's activity awareness
The Social Web Cockpit
The Social Web Cockpit integrates different services that have been developed in the Social Web research programme at GMD-FIT to support a knowledge sharing community. This includes a web-search based on recommendations, a concept index to develop a community vocabulary, shared workspaces for knowledge sharing, and an awareness service
Supporting End-User Development through a New Composition Model: An Empirical Study
End-user development (EUD) is much hyped, and its impact has outstripped even the most optimistic forecasts. Even so, the vision of end users programming their own solutions
has not yet materialized. This will continue to be so unless we in both industry and the research community set ourselves the ambitious challenge of devising end to end an end-user application development model for developing a new age of EUD tools. We have embarked on this venture, and this paper presents the main insights and outcomes of our research and development efforts as part of a number of successful EU research projects. Our proposal not only aims to reshape software engineering to meet the needs of EUD but also to refashion its components as solution building blocks instead of programs and software developments. This
way, end users will really be empowered to build solutions based on artefacts akin to their expertise and understanding of ideal solution
