Organization politics and the role of accounting

This paper views the organization as an open political system. The way that organizations are structured makes inevitable the creation of sectional interests and differentiates the understanding of organizational goals. Decision-making is viewed as a power game between competing interest groups over the control of organizational resources. Power relations are generated and power is accumulated to the divisions that have control of scarce organizational resources or to those who cope most successfully with uncertainty. Accounting information is used as an argument that justifies demands from organizational actors or for the rationalization of decisions made.peer-reviewe

Heterofunctional Linking Agents for the Synthesis of Well-Defined Block Copolymers of Dimethylsiloxane and tert-Butyl Methacrylate or 2-Vinylpyridine

Heterofunctional linking agents for the synthesis of block copolymers of dimethylsiloxane and tert-butyl methacrylate or 2-vinylpyridine were studied. Addition and removal of the reagents were performed using break-seals and constrictions. Results indicated that the molecular and compositional homogeneity was high which was supported by the narrow molecular and compositional peaks obtained by size exclusion chromatography (SEC)

Evaluation of Gas Generation Potential Using Thermal Maturity Modelling—The Katakolo Case: A Probable Pathway to Energy Transition

It is evident that the increased focus on energy transition, will increase the demand for gas as it is the transitional fuel to the net zero CO2 emission era. The West Katakolo field is the only oil and gas discovery in Western Greece, and it is operated by Energean. The three offshore West Katakolo wells have defined both the oil and the gas zones, while onshore exploration wells have penetrated biogenic gas-saturated Plio-Pleistocene sands. This study assesses the gas generation potential of the local Plio-Pleistocene and Triassic sources using thermal maturity modelling based on the available legacy data, with limitations being addressed by running several case-scenarios. In conclusion, this study supports the generation of thermogenic and biogenic gas from the Triassic and Plio-Pleistocene sources respectively, demonstrating the importance of maturity modelling in hydrocarbon exploration, applied on the Katakolo case; a potential gas source to facilitate the energy transition in Greece

Unbiased Plasmonic-Assisted Integrated Graphene Photodetectors.

Photonic integrated circuits (PICs) for next-generation optical communication interconnects and all-optical signal processing require efficient (∼A/W) and fast (≥25 Gbs-1) light detection at low (<pJbit-1) power consumption, in devices compatible with Si processing, so that the monolithic integration of electro-optical materials and electronics can be achieved consistently at the wafer scale. Graphene-based photodetectors can meet these criteria, thanks to their broadband absorption, ultra-high mobility, ultra-fast electron interactions, and strong photothermoelectric effect. High responsivities (∼ 1 A/W), however, have only been demonstrated in biased configurations, which introduce dark current, noise, and power consumption, while unbiased schemes, with low noise and zero consumption, have remained in the ∼ 0.1 A/W regime. Here, we consider the unbiased asymmetric configuration and show that optimized plasmonic enhanced devices can reach for both transverse-electric and transverse-magnetic modes (at λ = 1550 nm), ∼A/W responsivity, and ∼ 100 GHz operation speed at zero power consumption. We validate the model and material parameters by simulating experimental devices and derive analytical expressions for the responsivity. Our comprehensive modeling paves the way for efficient, fast, and versatile optical detection in PICs with zero power consumption

Timescale dependent sign of amorphous titanium dioxide thermo-optic coefficient

We report on the thermo-optic properties of electron-beam evaporated amorphous titanium dioxide (TiO 2 ) at different timescales. We investigate the thermo-optic response of TiO 2 from static regime down to the micro-second regime by applying Joule heating on hybrid metallo-dielectric integrated Mach-Zehnder interferometers. We show that amorphous TiO 2 exhibits a very large negative thermo-optical coefficient in the range of -6.5×10 −4 K −1 at 1550 nm at typical timescales of a few seconds. Such a slow thermo-optic response is consistent with an organic origin of amorphous TiO 2 negative thermo-optic coefficient. However, when observed at the micro-second timescale, we show that the same amorphous TiO 2 has a positive thermo-optic coefficient, just like many other materials. Based on our results, TiO 2 can be conveniently deployed in energy-effective integrated optic devices by taking into account the specific multi-timescale thermo-optic properties of this material
