Business Models and Technological Innovation
Business models are fundamentally linked with technological innovation, yet the business model construct is essentially separable from technology. We define the business model as a system that solves the problem of identifying who is (or are) the customer(s), engaging with their needs, delivering satisfaction, and monetizing the value. The framework depicts the business model system as a model containing cause and effect relationships, and it provides a basis for classification. We formulate the business model relationship with technology in a two-way manner. First, business models mediate the link between technology and firm performance. Secondly, developing the right technology is a matter of a business model decision regarding openness and user engagement. We suggest research questions both for technology management and innovation, as well as strategy

UPC++ v1.0 Programmer’s Guide, Revision 2020.3.0
UPC++ is a C++11 library that provides Partitioned Global Address Space (PGAS) programming. It is designed for writing parallel programs that run efficiently and scale well on distributed-memory parallel computers. The PGAS model is single program, multiple-data (SPMD), with each separate constituent process having access to local memory as it would in C++. However, PGAS also provides access to a global address space, which is allocated in shared segments that are distributed over the processes. UPC++ provides numerous methods for accessing and using global memory. In UPC++, all operations that access remote memory are explicit, which encourages programmers to be aware of the cost of communication and data movement. Moreover, all remote-memory access operations are by default asynchronous, to enable programmers to write code that scales well even on hundreds of thousands of cores
A UPC++ Actor Library and Its Evaluation on a Shallow Water Proxy Application
Programmability is one of the key challenges of Exascale Computing. Using the actor model for distributed computations may be one solution. The actor model separates computation from communication while still enabling their over-lap. Each actor possesses specified communication endpoints to publish and receive information. Computations are undertaken based on the data available on these channels. We present a library that implements this programming model using UPC++, a PGAS library, and evaluate three different parallelization strategies, one based on rank-sequential execution, one based on multiple threads in a rank, and one based on OpenMP tasks. In an evaluation of our library using shallow water proxy applications, our solution compares favorably against an earlier implementation based on X10, and a BSP-based approach

Sparrow therapeutics exit strategy
The case focuses on Ken Powers, cofounder and chief executive officer of Sparrow Therapeutics, whose young biotechnology company has reached a critical stage where he has to decide whether or not to sell. The company's three main sets of investors have different priorities: (1) a quick cash sale now, (2) delay sale for about a year if returns are greater, and (3) delay sale for 2 years, build company value, and retain autonomy. What choice would be best for the company, for its investors-and for Ken himself? And when would be the best time to implement the exit strategy

Strategies for Competing in the Automotive Industry’s Software Ecosystem: Standards and Bottlenecks
The automotive industry includes many actors engaged in software that span small and large companies within old and new sectors. This paper focuses on the controlling position of car manufacturers in the automotive software ecosystem and suggests three strategies for participating software innovators – contesting, cooperating and circumventing. The strategies are exemplified with current cases: Tesla as contestation, Bosch cooperation with a car manufacturer in a data collection project as a basis for future services, and circumventing in a project based on the mobile Internet

The relational antecedents of project-entrepreneurship: Network centrality, team composition and project performance
The relational antecedents of project-based enterprises have not yet received systematic investigation. These ventures are typically created by individual freelancers who are usually embedded in networks of collaborative relationships that convey the information and resources required to carry out new projects. Using a relational perspective of entrepreneurial discovery and team composition, we analyze the performance determinants of project-entrepreneurs, namely the individuals who are responsible for launching and carrying out those projects. We argue that project-entrepreneurs’ performance is related to their degree of centrality within the social network, and their familiarity with the selected project-team as captured by the distribution of ties among team members. We test our hypotheses within the Hollywood Film Industry over the period 1992–2003. The findings point to the existence of diminishing returns to centrality and performance benefits from assembling teams that combine old-timers and newcomers. The theoretical contributions and implications of the study are discussed
Student perceptions and experiences of problem-based learning in first year undergraduate sports therapy
Problem-based learning (PBL) has long been used as a means to foster critical thinking and student autonomy. However, few studies have investigated the effectiveness of PBL in Sports Therapy. The aim of this study was to examine first year Sports Therapy students' perceptions of PBL. Results revealed that students perceived PBL as vocationally relevant, by enabling them to work in and across groups, whilst also engaging with a wider range and depth of information compared to more traditional methods of curriculum delivery. External observations of the lecturers input sessions were made by an impartial re- searcher. The implications of the study are that PBL appears to be a professionally suitable and appropriate learning modality for Sports Therapy students

Business Models and Value
We identify the business model as the mechanism that explains how a firm engages with consumers to create and capture value. We look into the literatures of marketing, strategy, entrepreneurship to identify 4 important – mutually exclusive - theoretical types: dyadic product; dyadic solutions; triadic matchmaking; and triadic multi-sided. Each of these business model types implies a different set of behaviors by the consumer; different actions by the firm; and give rise to differences in value for the consumer; profit opportunities for the firm; different organizational designs and corresponding entrepreneurial pathways. Our paper draws on and extends the current literature on the demand side perspective and effectuation
Neighborhood dynamics and price effects of Superfund site clean-up
Numerous hedonic price analyses estimate price effects associated with hazardous waste site remediation or other environmental variation. This paper estimates a neighborhood transition model to capture the direct price effect from Superfund site clean-up and the indirect price effects arising from residential sorting and changes in investment in the housing stock following clean-up. First-difference models of neighborhood change and a national sample are used. This approach fails to find consistent positive direct price effects. Positive indirect effects, however, may arise through residential sorting and neighborhood investment spurred by remediation. The findings can be sensitive to policy endogeneity and model specification
