TL;DR: Two-particle correlations in relative azimuthal angle and pseudorapidity are measured using the ATLAS detector at the LHC and the resultant Δø correlation is approximately symmetric about π/2, and is consistent with a dominant cos2Δø modulation for all ΣE(T)(Pb) ranges and particle p(T).
Abstract: Two-particle correlations in relative azimuthal angle (Delta phi) and pseudorapidity (Delta eta) are measured in root S-NN = 5.02 TeV p + Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1 mu b(-1) of data as a function of transverse momentum (p(T)) and the transverse energy (Sigma E-T(Pb)) summed over 3.1 < eta < 4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2 < vertical bar Delta eta vertical bar < 5) "near-side" (Delta phi similar to 0) correlation that grows rapidly with increasing Sigma E-T(Pb). A long-range "away-side" (Delta phi similar to pi) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small Sigma E-T(Pb), is found to match the near-side correlation in magnitude, shape (in Delta eta and Delta phi) and Sigma E-T(Pb) dependence. The resultant Delta phi correlation is approximately symmetric about pi/2, and is consistent with a dominant cos2 Delta phi modulation for all Sigma E-T(Pb) ranges and particle p(T).

17 Mar 2003TL;DR: It is argued that such modularisation makes it possible to establish early trade-offs between aspectual requirements hence providing support for negotiation and subsequent decision-making among stakeholders.
Abstract: An effective requirements engineering (RE) approach must harmonise the need to achieve separation of concerns with the need to satisfy broadly scoped requirements and constraints. Techniques such as use cases and viewpoints help achieve separation of stakeholders' concerns but ensuring their consistency with global requirements and constraints is largely unsupported. In this paper we propose an approach to modularise and compose such crosscutting, aspectual requirements. The approach is based on separating the specification of aspectual requirements, non-aspectual requirements and composition rules in modules representing coherent abstractions and following welldefined templates. The composition rules employ informal, and often concern-specific, actions and operators to specify how an aspectual requirement influences or constrains the behaviour of a set of non-aspectual requirements. We argue that such modularisation makes it possible to establish early trade-offs between aspectual requirements hence providing support for negotiation and subsequent decision-making among stakeholders. At the same time early separation of crosscutting requirements facilitates determination of their mapping and influence on artefacts at later development stages. A realisation of the proposed approach, based on viewpoints and the eXtensible Markup Language (XML), supported by a tool called ARCaDe and a case study of a toll collection system is presented.

TL;DR: This article explored associations between ownership and management profiles and the performance and objectives of family firms using data from privately held family firms in the United Kingdom, and found that the management rather than the ownership structure of a family firm was generally associated with selected firm-performance indicators and non-financial company objectives.
Abstract: Agency and stewardship theories are used to explore associations between ownership and management profiles and the performance and objectives of family firms. Using data from privately held family firms in the United Kingdom, a range of performance measures and objectives were examined. Multivariate regression analysis detected that closely held family firms did not report superior firm performance. The results show that the management rather than the ownership structure of a family firm was generally associated with selected firm-performance indicators and nonfinancial company objectives. Although family CEOs were associated with lower propensity to export, presented evidence generally fails to suggest that private family firms should avoid employing family members in management roles.

TL;DR: Phloem sap analysis revealed that unlike Gln, Asn is not efficiently transported to developing kernels, apparently causing reduced kernel production, and Cytoimmunochemistry and in situ hybridization revealed that GS1-3 is present in mesophyll cells, whereasGS1-4 is specifically localized in the bundle sheath cells.
Abstract: The roles of two cytosolic maize glutamine synthetase isoenzymes (GS1), products of the Gln1-3 and Gln1-4 genes, were investigated by examining the impact of knockout mutations on kernel yield. In the gln1-3 and gln1-4 single mutants and the gln1-3 gln1-4 double mutant, GS mRNA expression was impaired, resulting in reduced GS1 protein and activity. The gln1-4 phenotype displayed reduced kernel size and gln1-3 reduced kernel number, with both phenotypes displayed in gln1-3 gln1-4. However, at maturity, shoot biomass production was not modified in either the single mutants or double mutants, suggesting a specific impact on grain production in both mutants. Asn increased in the leaves of the mutants during grain filling, indicating that it probably accumulates to circumvent ammonium buildup resulting from lower GS1 activity. Phloem sap analysis revealed that unlike Gln, Asn is not efficiently transported to developing kernels, apparently causing reduced kernel production. When Gln1-3 was overexpressed constitutively in leaves, kernel number increased by 30%, providing further evidence that GS1-3 plays a major role in kernel yield. Cytoimmunochemistry and in situ hybridization revealed that GS1-3 is present in mesophyll cells, whereas GS1-4 is specifically localized in the bundle sheath cells. The two GS1 isoenzymes play nonredundant roles with respect to their tissue-specific localization.

TL;DR: It is suggested that the narrow view of contingency that relies on responses to generally applicable questionnaires needs to be replaced by a more tailored approach that takes into account the context of specific organizations.
