Constraining the (Low-Energy) Type-I Seesaw
The type-I seesaw Lagrangian yields a non-generic set of active-sterile
oscillation parameters - the neutrino mass eigenvalues and the physical
elements of the full mixing matrix are entwined. For this reason one is able
to, in principle, test the model by performing enough measurements which are
sensitive to neutrino masses and lepton mixing. We point out that for light
enough right-handed neutrino masses - less than 10 eV - next-generation
short-baseline neutrino oscillation experiments may be able to unambiguously
rule out (or "rule in") the low energy seesaw as the Lagrangian that describes
neutrino masses. These types of searches are already under consideration in
order to address the many anomalies from accelerator neutrino experiments
(LSND, MiniBooNe), reactor neutrino experiments (the "reactor anomaly") and
others. In order to test the low-energy seesaw, it is crucial to explore
different oscillation channels, including nu_e and nu_mu disappearance and
nu_mu to nu_tau appearance.Comment: 15 pages, five figure
Management of e-technology in China
"e" technology is bringing about many challenges for companies, in particular for their managers. This concerns a vast range of business processes in many sectors of the economy and in nearly every country of the world. In rapidly industrializing China, companies and other organizations are actively finding their way by adapting, developing and exploiting new e-technologies. The paper's focus is the identification of the management issues in implementing e-technology in China. The paper reports on research into difficulties of establishing and operating e-business in China. In particular, it discusses management related to e-technology sharing and application. A brief review of literature is followed by the analysis of three recent case studies: an international IT services alliance, a financial services provider and an international manufacturing joint venture. All case companies are applying e-technology in China, but the role of e-technology differs in the three cases: adding a service line to the existing business processes; developing a new business process; and increasing efficiency and effectiveness in business processes. The conclusions present the emerging management issues: cooperation is a key asset in networking; the choice of business models plays an important role; adequate management attention for details such as a training program is require
