During the last decade, the scope of IT outsourcing arrangements evolved from a dyadic client vendor relationship to a multi-sourcing environment characterized by sourcing inter-dependent services from multiple vendors. This study addresses the journey of a large client firm in the retail sector who experienced that managing a multi-sourcing arrangement differs significantly from managing bilateral (i.e. dyadic) relationships. The journey describes various obstacles that the retailer faced in managing an IT multi-sourcing arrangement, their improvement initiatives, and subsequently a strategic transformation towards a digital ecosystem.
Sector coupling has traditionally been a rather narrow concept to analyze synergies of urban system integration with particular focus on transport, energy and waste systems. The evolution of the fifth generation (5G) networks with its fixed and mobile convergence fundamentally enlarges the potentials of sector coupling in network industries. 5G has the character of an application-agnostic General-Purpose Technology (GPT) building a critical input for a large and open set of downstream Internet of Things (IoT) applications. Due to this vertical relationship vertical sector coupling gains particular relevance in all network industries and beyond in many areas of the App economy. Moreover, the potentials of 5G based horizontal sector coupling increases.

Spinal cord Injury can have a debilitating and traumatic effect on affected individuals. The impact is far reaching, including emotional, physical, economic, and social. This impact id not only on the affected individuals, but also their family members, caregivers and the society as well. Prevalence of pressure ulcers was found to be 33.9% in patients with quadriplegia, 47.4% in patients with paraplegia, and 9.6% in patients who had hemiplegia. Pressure ulcers are a debilitating and undesirable complication of traumatic spinal cord injury that can be prevented using wearable sensors and mobile devices. Weight offloading is one of the recommended solutions to prevent pressure ulcers. Our team designed and developed a mobile application that was tied to a pressure sensor mat, used to track and monitor weight offloading. Our sensor-based system was designed to measure two outcomes-one, verify weight offloading and two-to investigate if prompting an individual can help them remember to weight offload. Our analysis showed that most patients remember to perform weight offloading exercises with initial assistance of technology. We designed a new threshold-based algorithm for our sensor-based system to detect weight offload called COMpredict. The prediction accuracies of the algorithm are relatively high with approximately 90% of accuracy for most weight shifting tests and 70.49% for wheelchair push up test.

With the increasing demand to efficiently deploy DNNs on mobile edge devices, it becomes much more important to reduce unnecessary computation and increase the execution speed. Prior methods towards this goal, including model compression and network architecture search (NAS), are largely performed independently and do not fully consider compiler-level optimization which is a must-do for mobile acceleration. In this work, we propose NPAS, a compiler-aware unified network pruning and architecture search and the corresponding comprehensive compiler optimizations supporting different DNNs and different pruning schemes, which bridge the gap of weight pruning and NAS. Our framework achieves 6.7 ms, 5.9 ms, and 3.9 ms ImageNet inference times with 78%, 75% (MobileNet-V3 level), and 71% (MobileNet-V2 level) Top-1 accuracy respectively on an off-the-shelf mobile phone, consistently outperforming prior work.

Serverless computing is an emerging event-driven programming model that accelerates the development and deployment of scalable web services on cloud computing systems. Though widely integrated with the public cloud, serverless computing use is nascent for edge-based, IoT deployments. In this work, we present STOIC (Serverless Tele Operable Hybrid Cloud), an IoT application deployment and offloading system that extends the serverless model in three ways. First, STOIC adopts a dynamic feedback control mechanism to precisely predict latency and dispatch workloads uniformly across edge and cloud systems using a distributed serverless framework. Second, STOIC leverages hardware acceleration (e.g. GPU resources) for serverless function execution when available from the underlying cloud system. Third, STOIC can be configured in multiple ways to overcome deployment variability associated with public cloud use. We overview the design and implementation of STOIC and empirically evaluate it using real-world machine learning applications and multi-tier IoT deployments (edge and cloud). Specifically, we show that STOIC can be used for training image processing workloads (for object recognition) – once thought too resource-intensive for edge deployments. We find that STOIC reduces overall execution time (response latency) and achieves placement accuracy that ranges from 92% to 97%.

It is widely asserted that emerging technologies, innovation, and technological disruption lead to increased volatility among stock markets. At first glance, this might appear contradictory since, by definition, novel developments, information technology for example, should surely help to make firm-specific information available on a timelier basis. Starting from the economic theory that defines innovation as long-term, in the light of financial markets shortening investment time horizons to optimize returns and empirical evidence, this article reviews current research on the interplay between emerging technologies, innovation, and volatility. Since risk is commonly used as a proxy for uncertainty, and innovation is an example of true uncertainty, we explore emerging technologies and innovation in the context of return and volatility. We observe that idiosyncratic risk and, indeed, overall risk have increased as a result of emerging technologies. The main drivers of risk in the aforesaid inter play are the use of more complex methods to calculate the fundamental value of assets, over-enthusiasm with regard to innovation fuelling over-expectations that are nourished by herding behavior, asymmetric information and the world economy shifting towards one that is driven by intangible assets. Additionally, some properties of emerging technology and innovation can be defined as diffusive, persistent, heterogeneous, and momentum-oriented, which brings us back to the historical implications of technology bubbles.
