Critical social research in enterprise social network studies: a systematised overview and analysis
… on the internal use of Enterprise Social Networks (ESNs) within organizations, focusing on their impact on employee well-being and internal communication. It differentiates between critical social research (CSR) and administrative research (AR) on ESN use. CSR looks at power dynamics and …

DYNAMIC FUNCTIONAL CONNECTIVITY NETWORKS: NEW ANALYSIS AND INTERPRETATION STRATEGIES
Traditional brain network studies have implicitly assumed that functional connectivity between distinct brain regions is static over the recording period of resting state scans. Brain network organization must dynamically recognize, integrate and respond to internal and external stimuli across …

Diversity measurement for the email content of information workers
… workers are still understudied. Some social network studies claim that diverse information that passes through workers in the positions with diverse sources of information drives performance. However, such claims are rarely verified by empirical data. This study develops a measurement …

Community detection on urban street networks : a segmentation model for urban logistics policy and planning
… the community detection methods employed by network studies in a wide variety of contexts and adapts their use to the segmentation of an urban street network. In order to form partitions of urban street networks that are manageable as delivery territories or similar units of spatial …

Social Network Size: The Effect of Construal Priming on Social Groups
Four studies examined how people group their relationships with other people and how social groups are structured. Study 1 provided a baseline for the number and types of social groups that individuals construct as their social network. Studies 2 and 3 examined whether construal mindset changes the …

Overlapping communities on social networks : a self-falsifiable hierarchical detection algorithm
Community detection is a central topic in network studies, whereas no community detection algorithm can be optimal for all possible networks; thus it is important to identify whether the algorithm is suitable for a given network. We propose a multi-step algorithmic solution scheme for overlapping …

Assessment of geographical based load forecast approach in distribution planning
… a case study method was followed. Real network studies that were compiled in 2006 and 2007 were used. These network studies were based on GLF method and the legacy method. The load forecasts from the case studies were evaluated on forecast accuracy, how they influenced the planning of …

The Effect Of Hyperparameters In The Activation Layers Of Deep Neural Networks
Deep neural networks (DNNs), and artificial neural networks (ANNs) in general, have recently received a great amount of attention from both the media and the machine learning community at large. DNNs have been used to produce world-class results in a variety of domains, including image recognition, …

Inside The Lines: Essays on the Performance of Whole Organizational Networks
… is focused on the study of heterogeneous network performance. For decades, most strategy and organizational research has focused on understanding how networks influence a single “node,” typically an organization or individual. In contrast, I shift my perspective to view a whole network as …

Community at a distance: Ray Johnson's correspondence art network, 1955-75
… process, Johnson and his collaborators built a network of correspondence artists that challenged conventional modes of artistic production, distribution, and reception. My dissertation analyzes this form of artistic production as well as the model of community Johnson engendered through its …

Game Theoretical Approach for Joint Relay Selection and Resource Allocation in Mobile Device Networks
… due to the limited radio bandwidth, wireless network performance becomes a critical issue. Common mobile solutions are based on the centralized structure, which require an access point to handle all the communication requirement in the work area. The transmission performance of centralized …

Formation of branching angles at bifurcations of ant trail networks
Ants form dendritic trail networks around the nest to search for and exploit food sources located at the periphery of the network. Studies found these trail networks to be very efficient for the ants in terms of time and energy, which later was found stored in the bifurcation angle ([theta]) of the …

Integrate-and-fire modelling of neuronal systems with modulatory properties
… a simulation of an excitatory-inhibitory (E-I) network. The results show the potential of the application of the integrate-and-fire model in network studies.

“To try the speed": adventures in the development of Massachusetts railroads, 1826-1850
… made railroads the basis of organizational and network studies and measured their support by the allocation of public funds. They have overlooked rural capitalism and early rail technology. This project eschews economic and scientific determinism in favor of a humanistic approach influenced by …

Induction and Maintenance of Synaptic Plasticity
… states of a single synapse. The biochemical network involving calcium/calmodulin-dependent protein kinase II (CaMKII) and its regulating protein signaling cascade has been hypothesized to durably maintain the synaptic state in form of a bistable switch. Furthermore, it has been shown …

Network Analysis of the Financial Sector: A Comprehensive Perspective with Adaptive Joint LASSO Method
… Specifically, shock transmissions in financial network settings warrant attention to support regulatory or policy interventions for effectively mitigating or preventing the transmission of systemic risk. The thesis focuses on this important topic from various angles to answer the following …

Duality derived topological model of single phase four limb transformers for GIC and DC bias studies
… of transformers and through power transmission networks. The flow of these currents causes the magnetic cores of transformers to half-wave saturate. Saturated transformers pose problems for power system operators since they can cause harmonics, transformer heating, mal-operation of protection …

A historical view and proposal analysis of the strategic role of the transportation sector in the economic development of post-war Liberia
… to rebuilding the country's transportation network. Studies must be conducted to understand the cost benefit of rebuilding road network throughout the country. Once these studies are completed, a diligent effort to execute a plan must be initiated. For each policy to serve its significance, …

Macroscopic insights from mechanistic ecological network models in a data void
… of components at lower levels of organization. Network modeling and analysis, being a powerful tool that can capture the interconnections that embody complex behaviour, has therefore been at the forefront of complexity science. In ecology, the network paradigm is relatively young and there …

Prediction and measurement of special core analysis petrophysical parameters in the Nubian sandstone of the North Africa
… applicability and accuracy of artificial neural networks for estimating special core analysis (SCAL) parameters from minimal core training data and wireline logs. The SCAL data was obtained from measurements on core plugs undertaken at the Libyan Petroleum Institute (L.P.I). Previous neural …
