The ShaRInK framework: a holistic perspective on key categories of influences shaping individual perceptions of knowledge sharing

Purpose – This paper aims to present a holistic framework, termed ShaRInK (Sharer, Relations, Institution, Knowledge), that depicts key categories of influences that shape individual perceptions of knowledge sharing within an organisational setting. Design/methodology/approach – An exploratory and qualitative case study strategy in which empirical data were gathered from 24 interviewees that were based in four different branches (i.e. China, The Netherlands, the UK and the USA) of a single information technology services organisation. Findings – The findings led to a holistic framework that depicts four key categories of influences that shape knowledge sharing from an individual perspective: attitudes and characteristics of the sharers, relations between the sharers, institutions which act as a united entity on sharer perceptions and knowledge itself. Furthermore, the four key influences not only shape knowledge sharing independently but are intertwined and have a synergistic effect. The ShaRInK framework is formed by combining these. Originality/value – The findings indicate that knowledge sharing from an individual-level perspective is a more complex phenomenon than currently portrayed in the literature. All four key influences, each being fundamentally different in nature, and their relationships should be taken into account. Equally, the ShaRInK framework can be applied by organisations when developing a knowledge-sharing strategy or auditing existing strategies

Absorptive capacity: a process and structure approach

The aim of this study is to understand and explain different dimensions of absorptive capacity and the strategies used in practice to realise it. The theoretical and conceptual contribution of the study lies in the adoption of a dual process and structure approach, aiming at identifying, respectively, how learning takes place and what learning takes place. The study is based upon a case study research design to explore the manifestation of absorptive capacity processes and its relationship to knowledge structures in four company case studies. The findings of the research indicate that knowledge acquisition, transformation and integration involve successive iterations of codification, abstraction and diffusion of knowledge in relation to product concepts, process requirements and problem-solving approaches. This relates to the capability to adopt, simultaneously, different trajectories in terms of knowledge exploration and knowledge exploitation strategies. The combined adoption of these different strategies enables both strategic and operational flexibility and underlies the successful realisation of absorptive capacity

Bletchley Park : an untold story in Information Science

This paper explores the view of Bletchley Park (BP) as an untold story in Information Science. While a substantial amount of literature relating to the site and its operations has been published, these primarily focus on military and intelligence history, or technical and mathematical subjects, with limited coverage in information science. We argue that there is an untold story of BP as a complex information arena

Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements

Beyond Histones: Unveiling the Functional Roles of Protein Acetylation in Prokaryotes and Eukaryotes

Lysine acetylation plays a crucial role in cellular processes and is found across various evolutionary organisms. Recent advancements in proteomic techniques revealed the presence of acetylation in thousands of non-histone proteins. Here, we conducted extensive meta-analysis of 48 acetylomes spanning diverse organisms, including archaea, bacteria, fungi, protozoa, worms, plants, insects, crustacea, fish, and mammals. Our analyzes revealed a predominance of a single acetylation site in a protein detected in all studied organisms, and proteins heavily acetylated, with > 5–10 acetylated-sites, were represented by Hsp70, histone, or transcription GTP-biding domain. Moreover, using gene enrichment approaches we found that ATP metabolic processes, glycolysis, aminoacyl-tRNA synthetase pathways and oxidative stress response are among the most acetylated cellular processes. Finally, to better explore the regulatory function of acetylation in glycolysis and oxidative stress we used aldolase and superoxide dismutase A (SODA) enzymes as model. For aldolase, we found that K147 acetylation, responsible to regulate human enzyme, conserved in all phylogenic clade, suggesting that this acetylation might play the same role in other species; while for SODA, we identified many lysine residues in different species present in the tunnel region, which was demonstrated for human and Trypanosoma cruzi, as negative regulator, also suggesting a conserved regulatory mechanism. In conclusion, this study provides insights into the conservation and functional significance of lysine acetylation in different organisms emphasizing its roles in cellular processes, metabolic pathways, and molecular regulation, shedding light in the extensive function of non-histone lysine acetylation

A search for resonances decaying into a Higgs boson and a new particle X in the XH → qqbb final state with the ATLAS detector

A search for heavy resonances decaying into a Higgs boson (H) and a new particle (X) is reported, utilizing 36.1 fb−1 of proton–proton collision data at collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. The particle X is assumed to decay to a pair of light quarks, and the fully hadronic final state is analysed. The search considers the regime of high XH resonance masses, where the X and H bosons are both highly Lorentz-boosted and are each reconstructed using a single jet with large radius parameter. A two-dimensional phase space of XH mass versus X mass is scanned for evidence of a signal, over a range of XH resonance mass values between 1 TeV and 4 TeV, and for X particles with masses from 50 GeV to 1000 GeV. All search results are consistent with the expectations for the background due to Standard Model processes, and 95% CL upper limits are set, as a function of XH and X masses, on the production cross-section of the resonance

Qualidade do azeite e sua relação com a cultivar e o clima em Portugal

A qualidade do azeite pode ser um elemento diferenciador, permitindo a prática de melhores preços num mercado cada vez mais competitivo. Os constituintes que mais têm sido apontados como tendo propriedades benéficas para a saúde são a composição acídica elevada em monoinsaturados, os valores elevados de tocoferóis, nomeadamente do atocoferol (vitamina E), e de polifenóis. A cultivar, a temperatura e o índice de maturação são variáveis que influenciam alguns dos parâmetros que estão associados à qualidade do azeite. No âmbito do projeto Futurolive, financiado pela FCT, as cultivares Arbequina, Cobrançosa, Galega, Picual e Verdeal foram ensaiadas em Mirandela, Santarém, Elvas e/ou Moncarapacho (Algarve) durante 2 anos. Fizeram-se medições nas plantas, na atmosfera e no solo. No azeite extraído em todas as localizações e olivais, fizeram-se análises detalhadas (análise sensorial, acidez, índice de peróxidos, espectrofotometria, horas rancimat, tocoferóis, polifenóis, esteróis, ácidos gordos totais, e triglicéridos). Todas as amostras foram classificadas como azeite Virgem Extra, obtiveram na análise sensorial uma classificação final igual ou superior a 6,5 e índices de peróxidos, na generalidade dos casos, muito inferiores a 20 meq 0 2 kg· 1 . As cultivares Picual e Verdeal distinguiram-se por valores muito superiores de horas de rancimat, A 'Cobrançosa' e 'Galega' apresentam os valores mais elevados de a-tocoferol. A concentração de polifenóis e de ácido oleico foi mais elevada na 'Verdeal' e 'Picual'. A localização parece ter influência nos teores de a-tocoferol, sendo que em Mirandela estes teores foram consistentemente mais elevados. Os teores de polifenóis são muito influenciados pelo índice de maturação. Relações entre a temperatura durante a maturação e as concentrações dos principais parâmetros associados à qualidade são apresentadas e discutidas. Consequências do aumento da temperatura devido às alterações climáticas são discutidas
