CT, e-government and electronic participation have become increasingly important in the public sector and the social sphere in recent years.This book presents 53 of the papers accepted for the dual IFIP EGOV-ePart conference 2016, which took place in Guimarães, Portugal, in September 2016. This conference, which consisted of five partially intersecting tracks, presented advances in the socio technological domain of the public sphere demonstrating cutting edge concepts, methods, and styles of investigation by multiple disciplines. The conference has been a premier academic forum for over 15 years and has a worldwide reputation as one of the top two conferences in the research domains of electronic, open and smart government, policy and electronic participation. The papers in this joint proceedings of the 2016 IFIP EGOV-ePart conference comprise accepted submissions from all categories and all tracks (with the exception of some 38 papers which are published separately).The book is divided into 9 sections: eParticipation, e-Government Evaluation, Open Data and Open Government, Governance, Smart Cities, e-Government Implementation and Adoption, Ph.D. Colloquium Papers, Posters, and Workshops.Offering a comprehensive overview of research and practice on electronic government and electronic participation, this book will be of interest to all those involved in the socio-technological domain of the public sphere.

While governments and researchers often focus on the opening of data through open data infrastructures, the adoption and use of open data infrastructures has received less attention, despite the fact that this use should result in the envisioned benefits. This study aims to examine to which extent and by which factors the acceptance and use of open data infrastructures by researchers can be influenced. For this purpose we use an integrated model of the Unified Theory of Acceptance and Use of Technology (UTAUT) and the two-stage Expectation Confirmation Theory of Information Systems continuance (ECT). Our research confirms the hypothesis that Perceived Usefulness (PU), Effort Expectancy (EE), Social Influence (SI) and Trust (T) in the pre-usage stage can be used to predict PU, EE, SI and T in the post-usage stage, which may subsequently influence the acceptance and use of open data infrastructures. Nevertheless, not all of our findings show support for applying the combined UTAUT-ECT model, and the findings suggest that the model needs to be specified and adapted for the domain of open data. We recommend future research to develop models for the acceptance and use of technologies that are more specific to the context of open data.

We present new results for the amplitude $A_2$ for a kaon to decay into two pions with isospin $I=2$: Re$A_2 = 1.50(4)_\mathrm{stat}(14)_\mathrm{syst}\times 10^{-8}$ GeV; Im$A_2 = -6.99(20)_\mathrm{stat}(84)_\mathrm{syst}\times 10^{-13}$ GeV. These results were obtained from two ensembles generated at physical quark masses (in the isospin limit) with inverse lattice spacings $a^{-1}=1.728(4)$ GeV and $2.358(7)$ GeV. We are therefore able to perform a continuum extrapolation and hence largely to remove the dominant systematic uncertainty from our earlier results, that due to lattice artefacts. The only previous lattice computation of $K\to����$ decays at physical kinematics was performed using an ensemble at a single, rather coarse, value of the lattice spacing ($a^{-1}\simeq 1.37(1)$ GeV). We confirm the observation that there is a significant cancellation between the two dominant contributions to Re$A_2$ which we suggest is an important ingredient in understanding the $��I=1/2$ rule, Re$A_0$/Re$A_2\simeq 22.5$, where the subscript denotes the total isospin of the two-pion final state. Our result for $A_2$ implies that the electroweak penguin contribution to $��^\prime/��$ is Re($��^\prime/��)_\textrm{EWP}=-(6.6\pm 1.0)\times 10^{-4}$., 46 pages, 12 figures

There has been much speculation as to the origin of the ΔI = 1/2 rule (ReA0/ReA2 ~ 22.5). We find that the two dominant contributions to the ΔI = 3/2, K → π π correlation functions have opposite signs, leading to a significant cancelation. This partial cancelation occurs in our computation of ReA2 with physical quark masses and kinematics (where we reproduce the experimental value of A2) and also for heavier pions at threshold. For ReA0, although we do not have results at physical kinematics, we do have results for pions at zero momentum with mπ ~ 420 MeV [ReA0/ReA2 = 9.1 (2.1)] and mπ ~ 330 MeV [ReA0/ReA2 = 12.0 (1.7)]. The contributions which partially cancel in ReA2 are also the largest ones in ReA0, but now they have the same sign and so enhance this amplitude. The emerging explanation of the ΔI = 1/2 rule is a combination of the perturbative running to scales of O (2 GeV), a relative suppression of ReA2 through the cancelation of the two dominant contributions, and the corresponding enhancement of ReA0. QCD and electroweak penguin operators make only very small contributions at such scales.

We review the status of recent calculations by the RBC-UKQCD collaboration of the complex amplitude $A_2$, corresponding to the decay of a kaon to a two pion state with total isospin 2. In particular, we present preliminary results from two new ensembles: $48^3 \times 96$ with $a^{-1}=1.73$ GeV and $64^3 \times 128$ with $a^{-1}=2.3$ GeV, both at physical kinematics. Both ensembles were generated Iwasaki gauge action and domain wall fermion action with 2+1 flavours. These results, in comparison to our earlier ones on a $32^3$ DSDR lattice with $a^{-1}=1.36$ GeV, enable us to significantly reduce the discretization errors. The partial cancellation between the two dominant contractions contributing to Re($A_2$) has been confirmed and we believe that this cancellation is a major contribution to the $��I=1/2$ rule., 7 pages, presented at the 31st International Symposium on Lattice Field Theory (Lattice 2013), 29 July - 3 August 2013, Mainz, Germany

There has been much speculation as to the origin of the ��I = 1/2 rule (Re A_0/Re A_2 \simeq 22.5). We find that the two dominant contributions to the ��I=3/2, K \to ���� correlation functions have opposite signs leading to a significant cancellation. This partial cancellation occurs in our computation of Re A_2 with physical quark masses and kinematics (where we reproduce the experimental value of A_2) and also for heavier pions at threshold. For Re A_0, although we do not have results at physical kinematics, we do have results for pions at zero-momentum with m_�� \simeq 420 MeV (Re A_0/Re A_2=9.1(2.1)) and m_�� \simeq 330 MeV (Re A_0/Re A_2=12.0(1.7)). The contributions which partially cancel in Re A_2 are also the largest ones in Re A_0, but now they have the same sign and so enhance this amplitude. The emerging explanation of the ��I=1/2 rule is a combination of the perturbative running to scales of O(2 GeV), a relative suppression of Re A_2 through the cancellation of the two dominant contributions and the corresponding enhancement of Re A_0.
