Company Growth and Its Main Factors

Analyzing factors exerting in fluence on the company growth being expressed in production in crease the author divide them into direct factors: manpower resources used in production, their size and qualifications, quality and quantity of work done by those employed in material production, end in direct factors: quality and quantity of means of labour employed in production, fixed and turnover funds employed in production. Further analysis deals with the Influence exerted by lebour productivity (efficiency) on the company growth. While defining the essence of productivity the author comes to the conclusion that the importance of productivity growth lies in the fact that as a main factor of production volume growth, through reduction of costs end price and through in crease of individual incomes it ensures improvement of living standards. The author proceeds next to discussing coefficients used in measuring labour productivity. Further analysis encompasses labour productivity at the national and sectional levels. The article ends with presentation of some indices used for measuring labour productivity.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę

Observation of same-sign WW production from double parton scattering in proton-proton collisions at s\sqrt{s} = 13 TeV

International audienceThe first observation of the production of W$^\pm$W$^\pm$ bosons from double parton scattering processes using same-sign electron-muon and dimuon events in proton-proton collisions is reported. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ recorded at a center-of-mass energy of 13 TeV using the CMS detector at the CERN LHC. Multivariate discriminants are used to distinguish the signal process from the main backgrounds. A binned maximum likelihood fit is performed to extract the signal cross section. The measured cross section for production of same-sign W bosons decaying leptonically is 80.7 $\pm$ 11.2 (stat) $^{+9.5}_{-8.6}$ (syst) $\pm$ 12.1 (model) fb, whereas the measured fiducial cross section is 6.28 $\pm$ 0.81 (stat) $\pm$ 0.69 (syst) $\pm$ 0.37 (model) fb. The observed significance of the signal is 6.2 standard deviations above the background-only hypothesis
